The stator assembly 210 of the electromagnetic actuator 1000 according to the embodiment of the present application will be described below with reference to the accompanying drawings.

As shown in Figures 59, 60, 61 and 62, a stator assembly 210 of an electromagnetic actuator 1000 according to an embodiment of the present application includes: a plurality of core assemblies 211, a plurality of winding assemblies 212 and a plurality of insulating frames 213.

The plurality of core assemblies 211 are stacked in sequence along the axial direction of the stator assembly 210 .

The plurality of winding assemblies 212 are disposed on the plurality of core assemblies 211 .

An insulating frame 213 is provided between each core assembly 211 and the winding assembly 212 .

It can be seen from the above structure that the stator assembly 210 of the electromagnetic actuator 1000 of the embodiment of the present application is composed of an iron core assembly 211, a winding assembly 212 and an insulating frame 213, and an insulating frame 213 is provided between each iron core assembly 211 and the winding assembly 212 to ensure the performance of the stator assembly 210, and to make the structure of the stator assembly 210 simple, thereby reducing the difficulty of assembling the stator assembly 210.

In some embodiments, in combination with Figures 41-48, the core assembly 211 includes a stator core 2014, and the stator core 2014 includes: a stator tooth portion 2141 and a stator yoke portion 2142, the stator tooth portion 2141 includes a plurality of first laminations 21411 stacked along the axial direction of the stator assembly 210, the stator yoke portion 2142 is formed in a ring shape and is arranged on the stator tooth portion 2141, at least a portion of the stator yoke portion 2142 is located on one side of the stator tooth portion 2141 so that a winding groove 2133 is formed between the stator tooth portion 2141 and the stator yoke portion 2142, the winding assembly 212 includes a multi-phase winding, and the coils 2123 of the winding (the specific structure of the coil 2123 can be seen in Figure 65) are all placed on the winding groove 2133. Thereby, the winding assembly 212 is arranged on the core assembly 211 to ensure the working performance of the stator assembly 210 and reduce the difficulty of assembling the stator assembly 210 .

It should be noted that, by configuring the stator tooth 2141 to include a plurality of first laminations 21411 stacked along the axial direction of the stator assembly 210, the plurality of first laminations 21411 can effectively reduce the eddy current loss of the stator tooth 2141 compared to configuring the stator tooth 2141 as a whole conductor, thereby improving the thrust and efficiency of the electromagnetic actuator 1000.

In some embodiments, the winding groove 2133 is formed on one axial side of the stator tooth portion 2141 and is located on the radial outer periphery of the stator yoke portion 2142 , so as to facilitate placing the coil 2123 of the winding on the winding groove 2133 .

In some embodiments, as shown in FIGS. 41 to 48 , the stator yoke 2142 is disposed on one axial side of the stator tooth 2141. A winding groove 2133 is formed between the stator tooth 2141 and the stator yoke 2142, so that the coil 2123 of the winding is conveniently placed on the winding groove 2133, and the difficulty of matching the winding assembly 212 with the core assembly 211 is reduced, so as to ensure the working performance of the stator assembly 210.

In some embodiments, as shown in FIGS. 41 to 46 , the stator yoke 2142 includes a plurality of stacked second laminations 21422 , and the plurality of second laminations 21422 are stacked along the radial direction of the stator assembly 210 , so as to effectively reduce the eddy current loss of the stator teeth 2141 .

That is to say, the multiple first laminations 21411 of the stator tooth portion 2141 are stacked along the axial direction of the stator assembly 210, and the multiple second laminations 21422 of the stator yoke portion 2142 are stacked along the radial direction of the stator assembly 210. The axially stacked teeth and the radially stacked yoke portions can significantly weaken the eddy current loss in the stator tooth portion 2141.

In some embodiments, as shown in Figures 41 and 42, the stator teeth 2141 and the stator yoke 2142 are made of one-piece silicon steel sheets stamped and laminated. The one-piece stamping structure can also ensure the thrust and efficiency of the electromagnetic actuator 1000 while weakening the thrust fluctuation of the electromagnetic actuator 1000.

At the same time, the integrated stamping structure also has the advantages of less structural cross-section, less adhesiveness, high assembly accuracy and no influence on the thrust efficiency of the electromagnetic actuator 1000.

Of course, in other embodiments, as shown in Figures 44 and 45, the stator yoke 2142 can also be fixed on the stator teeth 2141 to form the stator core 2014, that is, the stator core 2014 can also be made by fixing independent stator yokes 2142 and stator teeth 2141.

In some embodiments, the stator yoke 2142 is connected to the stator teeth 2141 so that the relative positions of the stator yoke 2142 and the stator teeth 2141 are stable, thereby ensuring the working performance of the stator core 2014 .

In some embodiments, the stator yoke 2142 and the stator teeth 2141 are connected by laser welding.

It should be noted that the above-mentioned assembly method of the stator yoke 2142 and the stator teeth 2141 can make the stator core 2014 have the advantages of separate lamination and mature technology, and the stator core 2014 can be suitable for complex core assembly 211 structure.

In some other embodiments, as shown in Figures 45 and 46, the stator yoke 2142 is axially inserted and fixed in the axially stacked stator teeth 2141. In this way, the stator core 2014 can also be made by fixing the independent stator yoke 2142 and stator teeth 2141.

In some embodiments, the stator yoke 2142 is inserted into the stator teeth 2141 and is reinforced with the stator teeth 2141 by laser welding, which ensures that the stator yoke 2142 and the stator teeth 2141 are firmly connected while ensuring a certain assembly accuracy.

In addition, the above-mentioned matching form can significantly reduce the eddy current loss of the core assembly 211, while also improving the installation accuracy, reducing the impact on the thrust and efficiency of the linear motor, and weakening thrust fluctuations.

In some embodiments, as shown in FIG. 47 and FIG. 48 , the stator yoke 2142 includes a plurality of stacked second laminations 21422, and the plurality of second laminations 21422 are stacked in the axial direction of the stator assembly 210. That is, it is not limited to stacking the plurality of second laminations 21422 in the radial direction of the stator assembly 210, and the plurality of second laminations 21422 may also be stacked in the axial direction of the stator assembly 210. Since the axial stamping and stacking process of silicon steel sheets is very mature, the process feasibility of this technical solution is high.

In summary, the stator core 2014 is made of axially laminated silicon steel sheets fixed on axially laminated silicon steel sheets.

In some embodiments, the stator yoke 2142 and the stator teeth 2141 are connected by laser welding.

Through the above-mentioned matching method, the stator yoke 2142 and the stator tooth 2141 can be separately stacked, with high axial installation accuracy, without affecting the thrust and efficiency of the linear motor, and weakening thrust fluctuations.

In some embodiments, as shown in FIG. 41 to FIG. 46 , the stator yoke 2142 is a winding, and the winding is arranged along the circumference of the stator assembly 210. It should be noted that the winding here means that the stator yoke 2142 is formed by spirally winding a whole piece of silicon steel sheet around the axis, and its function is equivalent to the function of axially stacking silicon steel sheets to weaken the eddy current loss of the stator teeth 2141, that is, the eddy current loss in the stator yoke 2142 can be largely weakened.

In some embodiments, as shown in FIGS. 41 to 46 , a first center hole 21412 is formed on the stator tooth 2141, and the stator yoke 2142 is located in the first center hole 21412. This allows the stator yoke 2142 to be disposed on the stator tooth 2141, thereby reducing the difficulty of matching the stator tooth 2141 with the stator yoke 2142.

In some embodiments, as shown in FIGS. 41 to 46 , a second center hole 21421 is formed on the stator yoke 2142, and both the first center hole 21412 and the second center hole 21421 are formed as mounting holes for the stator core 2014. This facilitates the assembly of the stator core 2014 on the center rod 300, thereby achieving the matching connection between the stator core 2014 and the center rod 300.

In some embodiments, as shown in FIGS. 41 to 48 , at least one of the stator yoke 2142 and the stator tooth 2141 is formed with a positioning protrusion 21415 that cooperates with the center rod 300. In this way, during the assembly process, the stator yoke 2142 and the stator tooth 2141 can form an interference fit with the center rod 300. The combination ensures the connection strength and relative position stability between the core assembly 211 and the center rod 300, avoids the circumferential rotation of the core assembly 211 on the structure of the center rod 300 during movement, and improves the assembly accuracy of the stator yoke 2142 and the center rod 300, and significantly weakens the eddy current loss while reducing the impact on the thrust and efficiency of the linear motor.

In some embodiments, as shown in FIGS. 41 to 48 , positioning protrusions 21415 that cooperate with the center rod 300 are formed on the stator yoke 2142 and the stator teeth 2141 , so that the stator yoke 2142 and the stator teeth 2141 can form a tight fit with the center rod 300 .

In some embodiments, as shown in FIGS. 41-48 , a groove 20111 is formed on the stator tooth 2141 for cross-phase connection between the coils 2123 .

At the same time, by forming positioning protrusions 21415 that cooperate with the center rod 300 on the stator yoke 2142 and the stator tooth 2141, the alignment of the grooves 20111 can be ensured, thereby reducing the difficulty of wiring the coil 2123.

In some embodiments, as shown in Figures 49 to 53, the stator yoke 2142 is formed as an integral piece. That is, the stator yoke 2142 is not limited to being formed as a winding piece, but can also be formed as an integral piece to reduce the difficulty of forming the stator yoke 2142.

In some embodiments, as shown in FIGS. 49 to 53 , the stator yoke 2142 includes a body 21427 and a plug-in portion 21428, and the plug-in portion 21428 is formed on one side of the body 21427 along the axial direction of the stator assembly 210. The plug-in portion 21428 is used to realize the fixed connection between the stator yoke 2142 and the stator tooth 2141, and the connection difficulty between the stator yoke 2142 and the stator tooth 2141 is reduced.

In some embodiments, as shown in Figures 49-53, the stator tooth portion 2141 is made of axially laminated silicon steel sheets, and the stator yoke portion 2142 is machined from solid material, wherein the material of the stator yoke portion 2142 is soft magnetic material, and positioning protrusions 21415 that cooperate with the center rod 300 are formed on the stator yoke portion 2142 and the stator tooth portion 2141, and a groove 20111 is formed on the stator tooth portion 2141 for cross-phase connection between the coils 2123.

In some embodiments, in combination with Figures 49, 50 and 51, the plug-in portion 21428 is formed as a boss on the main body 21427, and a first connecting structure 21416 is formed on the stator tooth portion 2141. The first connecting structure 21416 is formed to be a dovetail groove, and the boss is inserted into the dovetail groove and fixed to the stator tooth portion 2141. At the same time, laser welding is used to further strengthen the connection strength between the stator yoke portion 2142 and the stator tooth portion 2141, thereby achieving a fixed connection between the stator yoke portion 2142 and the stator tooth portion 2141.

At the same time, the above structure can also enable the stator tooth portion 2141 to significantly weaken the eddy current loss in the core assembly 211, while also ensuring the thrust and efficiency of the linear motor.

In some embodiments, the same trapezoidal punch is used to punch out the first connection structure 21416 formed as a dovetail groove, so that the slot of the first connection structure 21416 becomes wider as it is closer to the outer edge of the stator tooth portion 2141. In this way, when the plug-in portion 21428 is inserted into the first connection structure 21416, because the slot width of the dovetail groove is smaller than the bottom width of the dovetail groove, the plug-in portion 21428 can be prevented from slipping out of the first connection structure 21416, thereby strengthening the fixing strength between the stator yoke portion 2142 and the stator tooth portion 2141.

In some embodiments, the opposite ends of the bottom of the dovetail groove are chamfered toward the inside away from the dovetail groove. The chamfer is formed by a punch with chamfered corners. Using a punch with chamfered corners can increase the service life of the punch. At the same time, by setting the chamfer on the dovetail groove, interference between the plug-in portion 21428 and the first connecting structure 21416 during the assembly process can be avoided, thereby ensuring that the plug-in portion 21428 can be normally inserted into the first connecting structure 21416 along the axial direction and complete the fixation of the stator yoke portion 2142 and the stator tooth portion 2141.

In addition, when the plug-in portion 21428 is inserted into the first connecting structure 21416, since the side surface of the plug-in portion 21428 and the bottom end surface of the main body 21427 form a rounded corner, the bottom end surface of the main body 21427 and the end surface of the stator tooth portion 2141 cannot fit together. Therefore, in this embodiment, an inclined surface inclined toward the center line of the plug-in portion 2142 is formed between the bottom end surface of the main body 21427 and the side surface of the plug-in portion 21428. When the side surface of the plug-in portion 21428 and the bottom end surface of the main body 21427 have rounded corners, the stator yoke portion 2142 and the stator tooth portion 2141 can be fit together, thereby ensuring the reliability of the structure.

In some embodiments, in combination with Figures 52 and 53, the stator yoke 2142 includes a main body 21427 and a plug-in portion 21428. The main body 21427 is arranged on the axial side of the plurality of first laminations 21411. The planar size of the main body 21427 is equal to the inner and outer diameters of the first laminations 21411. The plug-in portion 21428 is plugged into the first center hole 21412, thereby achieving a fixed connection between the stator yoke 2142 and the stator tooth portion 2141.

Optionally, in combination with Figures 52 and 53, a second anti-rotation protrusion 21417 is provided on the stator tooth 2141, and an anti-rotation groove 21425 is provided on the stator yoke 2142. The second anti-rotation protrusion 21417 is engaged in the anti-rotation groove 21425 to achieve fixed engagement between the stator tooth 2141 and the stator yoke 2142, preventing the stator tooth 2141 from rotating, further ensuring the alignment of the groove 20111, and reducing the difficulty of wiring the coil 2123.

In some embodiments, after the stator yoke 2142 and the stator teeth 2141 are connected by the second anti-rotation protrusion 21417 and the anti-rotation groove 21425, laser welding is used to further strengthen the connection strength between the stator yoke 2142 and the stator teeth 2141.

In some embodiments, as shown in Figures 52 and 53, a first boss structure 21426 is provided at the connection between the main body 21427 and the plug-in portion 21428 to prevent the connection between the main body 21427 and the plug-in portion 21428 from breaking and further enhance the mechanical strength of the connection.

In some embodiments, as shown in FIGS. 54 to 58 , a first connection structure 21416 and a second connection structure 21423 are formed on the stator yoke 2142 and the stator tooth 2141 , respectively, and the first connection structure 21416 cooperates with the second connection structure 21423 to achieve the cooperative connection between the stator yoke 2142 and the stator tooth 2141 .

In some embodiments, as shown in FIGS. 54 to 58 , the first connection structure 21416 is plugged into the second connection structure 21423. This allows the stator yoke 2142 to be plugged into the stator teeth 2141, reduces the difficulty of fixing the stator yoke 2142 and the stator teeth 2141, ensures the fixing quality, and stabilizes the relative position of the stator yoke 2142 and the stator teeth 2141.

In some embodiments, in combination with Figures 54-58, a plurality of second connection structures 21423 are provided below the stator yoke 2142, and the second connection structure 21423 is formed as a column structure, and the thickness of the column is the same as the thickness of the stator tooth portion 2141, and a plurality of first connection structures 21416 cooperating with the column structure are provided on the stator tooth portion 2141, and the first connection structure 21416 is formed as a dovetail groove, and the column structure is inserted into the dovetail groove at the corresponding position of the stator tooth portion 2141, so as to fix the stator yoke 2142 and the stator tooth portion 2141.

It should be noted that since the coil 2123 surrounds the stator yoke 2142 and is coiled and placed on the stator teeth 2141, when the electromagnetic actuator 1000 is running, the magnetic lines of force mainly move along the radial direction within the stator teeth 2141 and the axial direction within the stator yoke 2142, wherein the stator teeth 2141 can largely weaken the eddy current loss generated in the teeth through the axially stacked silicon steel sheets, and the stator yoke 2142 can weaken the eddy current loss in the stator yoke 2142 through the circumferentially wound silicon steel sheets.

In some embodiments, the stator yoke 2142 is formed by a process of stamping and then winding, wherein the same punch is used for stamping the column, and the punch shape is trapezoidal. If a square punch is used, assembly interference will form at the connection between the column structure and the stator yoke 2142 and the local area of the stator tooth 2141. At the same time, if the chamfered corners are not designed, the life of the punch will be greatly shortened, thereby increasing costs.

Therefore, this embodiment uses the same trapezoidal punch with rounded corners to process the second connection structure 21423, which can reduce the process cost and meet the process assembly requirements.

In addition, when the second connecting structure 21423 cooperates with the first connecting structure 21416, when the second connecting structure 21423 is inserted into the dovetail groove opened in the stator tooth portion 214, since the side surface of the second connecting structure 21423 and the bottom end surface of the stator yoke 2142 form a chamfer, there is a risk that the bottom end surface of the stator yoke 2142 and the end surface of the stator tooth portion 2141 cannot fit together. By adopting a trapezoidal punch, an inclined surface 21424 inclined toward the center line of the second connecting structure 21423 can be formed on the bottom end surface of the stator yoke 2142 and the side surface of the second connecting structure 21423 (as shown in Figure 58). This can ensure that the stator yoke 2142 and the stator tooth portion 2141 can fit together when the second connecting structure 21423 and the bottom end surface of the stator yoke 2142 have chamfers, thereby ensuring the reliability of the structure.

It should also be noted that since the same punch is used during stamping of the second connecting structure 21423, the width of the rolled second connecting structure 21423 will vary radially, wherein the closer to the radial outer edge of the stator yoke 2142, the wider the width of the second connecting structure 21423, thereby forming the stator yoke 2142 into a dovetail trapezoidal shape.

In some embodiments, as shown in Figure 57, the stator tooth portion 2141 is punched out at a fixed position to form a plurality of first connection structures 21416 formed as dovetail grooves. When the second connection structure 21423 is inserted into the first connection structure 21416, because the groove width of the dovetail groove is smaller than the bottom width of the dovetail groove, it can be ensured that the second connection structure 21423 cannot slip out of the first connection structure 21416, thereby strengthening the fixing strength between the stator yoke portion 2142 and the stator tooth portion 2141.

In some embodiments, as shown in Figure 57, the inner corner of the groove of the first connecting structure 21416 is provided with a chamfered corner. If the second connecting structure 21423 is provided with a structure matching the chamfered corner, it can avoid interference between the stator yoke 2142 and the stator tooth 2141 during installation, thereby ensuring that the second connecting structure 21423 on the stator yoke 2142 can be normally inserted into the first connecting structure 21416 of the stator tooth 2141 and complete the fixed connection between the stator yoke 2142 and the stator tooth 2141.

In summary, the stator yoke 2142 and the stator tooth 2141 of this embodiment, combined with the column structure of the second connection structure 21423 and the dovetail groove structure design of the first connection structure 21416, can form a mechanical connection between the spirally wound stator yoke 2142 and the axially stacked stator tooth 2141. At the same time, laser welding is used to further enhance the connection strength between the stator yoke 2142 and the stator tooth 2141.

In some embodiments, as shown in FIG. 59 to FIG. 66 , the core assembly 211 includes a first type of core 2111 and a second type of core 2112. In the axial direction of the stator assembly 210, there are multiple second type of cores 2112, and both ends of the multiple second type of cores 2112 are provided with the first type of core 2111. The end surface of the first type of core 2111 facing the second type of core 2112 is provided with a coil 2123, and both end surfaces of the second type of core 2112 are provided with a coil 2123. The coils 2123 on both sides of the second type of core 2112 have the same number of phases. This achieves the coordinated connection between the core assembly 211 and the winding assembly 212, and reduces the difficulty of connecting the coils 2123 of each phase.

In some embodiments, the coils 2123 at both ends of each second type iron core 2112 are connected in series, and the coils 2123 of the same phase arranged at intervals in the axial direction of the stator assembly 210 are welded and connected by connecting wires 2121. Thus, the welding connection of the coils 2123 of the same phase is achieved, and the performance of the winding assembly 212 is guaranteed.

In some embodiments, in combination with Figures 59-66, this embodiment uses a clever design to configure the core assembly 211 to be composed of a first type of core 2111 and a second type of core 2112. The coils 2123 on the same second type of core 2112 are in-phase coils, and the coils 2123 on the same second type of core 2112 are connected by welding. In this way, the traditional design is fully surpassed in many aspects such as layout space, production efficiency, processing difficulty, maintenance convenience, structural complexity and consistency of parts.

The same-phase coils 2123 are connected in series, and the bilateral coils inside the stator assembly 210 are also connected in series. When the coils 2123 are connected, the lead wires of the coils 2123 are welded to the connecting wires 2121 bent at the end of the coils 2123 to achieve line connection and reduce wiring errors.

In some embodiments, in combination with FIGS. 63, 64 and 65, the first type of iron core 2111 is provided with a first annular groove 21111, a wire arrangement groove 2013 and a groove 20111, and the structure of the insulating skeleton 213 is similar to that of the first type of iron core 2111.

The lead wire 21231 is bent at a right angle and wound from the inside to the outside, and is bent twice at the end of the coil 2123 to form a first lead end 2018. During assembly, the coil 2123 is nested in the first annular groove 21111, and the lead wire 21231 extends through the wire arrangement groove 2013 and the lead channel 2131 to the outside of the first type of iron core 2111 for wiring and power supply. This method has a simple structure, good consistency in processing methods, simple processing technology, fewer operating steps, and a large operating space, which is conducive to reducing costs and improving production efficiency.

Both sides of the second type of iron core 2112 have a first annular groove 21111, a wire arrangement groove 2013 and a groove 20111. The insulating skeleton 213 is nested in the first annular groove 21111, and the same-phase coil 2123 is nested on the insulating skeleton 213, wherein the two wire arrangement grooves 2013 are 180° apart, and the coil 2123 on one side is connected in series with the first wire outlet 2018 of the coil 2123 on the other side at the welding point through the first wire outlet 2018, so that the components have the same structure, the structure is simple, the production and processing efficiency is high, and it is conducive to mass production and cost control.

At the same time, by arranging the coils 2123 on both side end surfaces of the second type iron core 2112, the space utilization rate is high.

In some embodiments, according to the different opening directions of the lead wire channel 2131 of the insulating frame 213, there are two ways to bend the lead wire of the coil 2123. For example, the lead wire 21231 is bent from the top of the coil 2123; or, the lead wire 21231 is bent from the bottom of the coil 2123. The winding method of the coil 2123 is the same, both from the inside to the outside, and the winding method is simple.

In some embodiments, the connection between the coils 2123 of the same phase is also in series, and the connection points are still welded, which has good operability, simple process, and is conducive to production and processing. In addition, the welding points are on the outside, which is more intuitive during assembly and welding, which is conducive to avoiding wiring errors and improving production efficiency. Moreover, this method has a large operating space, is easy to operate, and saves working hours.

In summary, the core assembly 211 of the present embodiment is composed of stacked independent modules, and the module units are separated by insulating paper 2122. The basic components of each module are the core, the insulating frame 213 and the coil 2123. The processing technology of each part is simple, the structure is basically the same, the complexity of the structure is low, and the assembly is convenient.

The insulating frame 213 is provided between the core assembly 211 and the winding assembly 212 to achieve insulation matching between the core assembly 211 and the winding assembly 212, thereby ensuring the performance of the stator assembly 210.

At the same time, a lead channel 2131 extending radially along the core assembly 211 is set on the axial end face of the insulating skeleton 213 to facilitate leading the lead wire 21231 of the coil 2123 to the outside of the core assembly 211, thereby facilitating wiring of the coil 2123 and connecting to the power supply.

In some embodiments, as shown in FIGS. 123 to 127 , the outer peripheral wall of the insulating frame 213 is provided with a plurality of evenly spaced wire grooves 2132 , and at least one wire groove 2132 is connected to the lead-in channel 2131 , so as to facilitate leading out the connecting wire 2121 of the connecting coil 2123 .

It should be noted that by providing the insulating skeleton 213 of the present embodiment, the core assembly 211, the winding assembly 212 and the insulating skeleton 213 can be formed as independent components, thereby reducing the difficulty of designing the core assembly 211, the winding assembly 212 and the insulating skeleton 213. At the same time, the insulating skeleton 213 of the present embodiment has the advantages of low processing difficulty, convenient maintenance, simple structure and high consistency both in terms of layout space and production efficiency.

In some embodiments, as shown in FIGS. 123 to 127 , the insulating skeleton 213 is mainly composed of a lead channel 2131 , a second annular groove 2138 and a wire passing groove 2132 .

In some embodiments, in combination with Figures 123 and 126, the insulating skeleton 213 has six wire passing grooves 2132 in the circumferential direction of the extension, and the positions of the six wire passing grooves 2132 are evenly distributed, that is, the interval between two grooves is 60°, and a second annular groove 2138 is opened on the surface of the insulating skeleton 213, and a winding space is formed between the second annular groove 2138, the inner wall 2136 of the second annular groove 2138 and the outer wall of the second annular groove 2138, and the winding space is used to assemble the coil 2123.

In some embodiments, a second boss structure 2134 formed by the lead channel 2131 and an insulating portion 2135 formed by the wire groove 2132 are provided on the opposite side of the insulating skeleton 213 where the second annular groove 2138 is provided. The second boss structure 2134 and the insulating portion 2135 are mainly used to be nested with structural parts on the core assembly 211, which greatly improves space utilization and reduces the volume occupied by parts. Therefore, the volume of the entire structure can be reduced and the matching strength between the insulating skeleton 213 and the core assembly 211 is ensured.

Through the above-mentioned arrangement, when in use, the core assembly 211, the winding assembly 212 and the insulating skeleton 213 are assembled and combined into a single module (as shown in FIG. 127 ), wherein the insulating skeleton 213 is nested in the first annular groove 21111 on the surface of the core assembly 211, wherein the second boss structure 2134 of the insulating skeleton 213 is combined with the wire arrangement groove 2013 in the first annular groove 21111, and the insulating portion 2135 formed by the wire groove 2132 is aligned with the groove 20111 in the circumferential direction of the core assembly 211, so that the coils 2123 have a larger operating space when connected in series outside the core assembly 211, which is beneficial to the subsequent welding connection between the coils 2123 and facilitates operation.

It should be noted that, in some embodiments, since the stator assembly 210 is stacked up by modules, and the modules are assembled by the core assembly 211, the winding assembly 212 and the insulating frame 213, the module located at the end of the stator assembly 210 has only one side of the winding assembly 212 and the insulating frame 213, and the module located in the axial middle of the stator assembly 210 has both ends of the core assembly 211 provided with the winding assembly 212 and the insulating frame 213.

The lead of the coil 2123 passes through the lead channel 2131 on the insulating frame 213, and then passes through the wire groove 2132 to extend to the outer periphery of the core assembly 211. The series wiring inside the module is carried out at the part where the wire grooves 2132 of the insulating frames 213 on both sides are connected, and the wiring is carried out by welding. The wiring at the wire groove 2132 has a larger operating space.

At the same time, since the lead channel 2131 is provided on the surface of the insulating frame 213, the structure of the insulating frame 213 is unique, which can effectively avoid assembly and wiring errors and improve production efficiency.

In some embodiments, when connected to a three-phase power supply, not only do the winding coils inside the module need to be connected in series, but the modules connected to the same-phase power supply also need to be connected in series. Both the lead spacing angle and the lead and output angle are multiples of 60°. Therefore, six evenly distributed wire grooves 2132 are set along the circumferential direction of the extension on the insulating frame 213, which improves the versatility and utilization of parts, can greatly increase production efficiency, save costs, and facilitate mass production.

In some embodiments, an assembly hole 2137 is provided at the center of the insulating frame 213 to facilitate assembly of the insulating frame 213 and the core assembly 211. In the axial direction of the assembly hole 2137, the outer edge of the insulating frame 213 protrudes from the first annular groove 21111, and the inner edge of the insulating fixture 213 protrudes from the first annular groove 21111, thereby achieving insulation between the coil winding and the stator core.

In some embodiments, the inner wall 2136 is disposed around the outer circumference of the assembly hole 2137 to form a hollow cylinder with a certain wall thickness between the assembly hole 2137 of the insulation frame 213 and the second annular groove 2138 .

In some embodiments, a stepped limit platform is provided on the surface of the hollow cylinder, and two adjacent out-of-phase coils 2123 are separated by insulating paper 2122. The insulating paper 2122 is nested on the hollow cylinder where the wall thickness is thinner to facilitate fixing the insulating paper 2122. The structure is compact and the material utilization rate is high.

It should be noted that the specifications and quantity of the bolts 1016 and the positioning pins 1017 can be reasonably designed according to the actual mechanical strength requirements.

In some embodiments, as shown in Fig. 2, Fig. 3 and Fig. 4, a guide rod 400 is provided on the end cover 1012, and the guide rod 400 is movably matched with the other one of the movable assembly 220 and the stator assembly 210 to guide the moving direction of the housing 100 and one of the movable assembly 220 and the stator assembly 210. That is, one of the movable assembly 220 and the stator assembly 210 is fixedly connected to the housing 100, and the other of the movable assembly 220 and the stator assembly 210 is movably matched with the guide rod 400, so as to avoid the housing 100 from deflecting during the movement process, that is, to ensure that the housing 100 can move in a predetermined direction, and to ensure the accuracy of the movement of the housing 100.

Through the above configuration, when the electromagnetic actuator 1000 is applied to the vehicle 20000, the wheel 2000 can be moved in a predetermined direction, thereby ensuring the stability of the vehicle 20000 when driving.

In some embodiments, as shown in FIGS. 2 , 3 and 4 , a guide bearing 840 is disposed between the guide rod 400 and the other of the mover assembly 220 and the stator assembly 210 .

In some embodiments, the movable assembly 220 is fixedly connected to the housing 100, and the guide rod 400 and the stator assembly 210 move in coordination to guide the movement direction of the housing 100. The verticality and concentricity of the lower end of the stator assembly 210 are determined by the guide rod 400 and the guide bearing 840.

In some embodiments, as shown in FIG. 2 , a bearing mounting slot is provided at the upper end of the cylinder 1011 for assembling the bearing 170 . The bearing 170 positions the upper end of the stator assembly 210 . The verticality and concentricity of the upper end of the stator assembly 210 are determined by the top surface of the cylinder 1011 and the bearing 170 .

In summary, the main structure of the electromagnetic actuator 1000 in this embodiment is composed of a bearing 170 , a cylinder 1011 , a mover assembly 220 , a stator assembly 210 , a guide bearing 840 , and an end cover 1012 . Among them, the inside of the cylinder 1011 is attached with a mover assembly 220, and the bearing 170, the cylinder 1011, the end cover 1012 and the mover assembly 220 constitute the mover part of the electromagnetic actuator 1000. The inside of the stator assembly 210 is a coil winding. When three-phase electricity is passed, a moving magnetic field will be formed. The magnetic field acts on the mover part, and the stator assembly 210 and the mover assembly 220 generate an interaction force to make the casing 100 move up and down. Finally, the electromagnetic actuator 1000 realizes linear motion, and the linear motion of the casing 100 is controlled by adjusting the size and direction of the three-phase electricity to achieve the actual required motion state. In addition, this embodiment solves the problems of installation of the mover assembly 220 and the stator assembly 210, assembly of the mounting bracket 192, and movement and positioning of the casing 100 by reasonably designing the structure between the end cover 1012 and the cylinder 1011.

In some examples, when assembling the electromagnetic actuator 1000, the first step is to install the mover assembly 220 from the bottom of the cylinder 1011 into the inner surface of the cylinder 1011, the second step is to assemble the bearing 170 with the top surface of the cylinder 1011, and the third step is to put the guide bearing 840 into the mounting hole on the lower end surface of the stator assembly 210, then install the stator assembly 210 from the bottom of the cylinder 1011, insert the upper end of the stator assembly 210 into the bearing 170, and finally install the end cover 1011. 12 Install from the lower end of the cylinder 1011 upwards, insert the guide rod 400 into the guide bearing 840, extend the extension part 1014 into the slot 1013, connect the end cover 1012 and the cylinder 1011 through the bolt 1016 and the positioning pin 1017, push and pull the housing 100 to check whether the movement of the housing 100 is smooth. If not, check whether the guide rod 400 is assembled in place, whether the machined dimensions of each part exceed the standard, and finally power on the electromagnetic actuator 1000 to see if the movement is normal.

It is worth noting that the electromagnetic actuator 1000 of this embodiment adopts a split design structure for the cylinder 1011 and the end cover 1012, which is convenient for installing the stator assembly 210 and the mover assembly 220; by integrating the end cover 1012, the guide rod 400 and the mounting bracket 192 into an integrated design, the connection method between the various parts of the electromagnetic actuator 1000 is simplified, the assembly process and assembly time are reduced, the structural reliability is improved, and the weight is reduced; by integrating the guide rod 400 in the end cover 1012 and designing the extension part 1014 on the top surface of the end cover 1012 to cooperate with the inner surface of the cylinder 1011 for installation, it can be ensured that the center of the guide rod 400 and the cylinder 1011 coincide, thereby ensuring that the air gap between the stator assembly 210 and the mover assembly 220 is uniform; by adding a positioning pin 1017 between the end cover 1012 and the cylinder 1011, it is used to locate the installation direction of the end cover 1012 to prevent misinstallation.

In some embodiments, as shown in FIG. 5 , FIG. 6 and FIG. 8 , multiple sub-housings 101 are arranged along the circumferential direction, and the circumferential direction is substantially perpendicular to the axis. In other words, the multiple sub-housings 101 are not limited to being arranged along the axis of the electromagnetic actuator 1000, but can also be arranged along the circumferential direction of the electromagnetic actuator 1000, which can also reduce the difficulty of assembling the housing 100, and at the same time reduce the difficulty of assembling and maintaining the moving subassembly 220 and the stator assembly 210, avoiding the moving subassembly 220 The stator assembly 210 collides with the housing 100 during the assembly process to ensure the working performance of the mover assembly 220 and the stator assembly 210.

In some embodiments, as shown in FIG9, FIG10, FIG11 and FIG12, the plurality of sub-housings 101 include a first sub-housing 110 and a second sub-housing 120, the first sub-housing 110 is formed with a first cavity 115, the second sub-housing 120 is formed with a second cavity 125, and the first sub-housing 110 and the second sub-housing 120 are arranged opposite to each other so that the first cavity 115 and the second cavity 125 are enclosed to form an accommodating cavity 130. This reduces the difficulty of molding the accommodating cavity 130, and facilitates the arrangement of the mover assembly 220 and the stator assembly 210 in the accommodating cavity 130.

In some embodiments, as shown in FIG6 and FIG8 , the first sub-housing 110 and the second sub-housing 120 are rotatably connected. Here, it means that the first sub-housing 110 and the second sub-housing 120 are not only connected but also relatively rotatable, so that during the assembly process of the first sub-housing 110 and the second sub-housing 120, the first sub-housing 110 and the second sub-housing 120 can be firstly rotatably connected, and after being connected in place, at least one of the first sub-housing 110 and the second sub-housing 120 can be rotated to form the housing 100, thereby reducing the difficulty of assembling the housing 100.

That is to say, the casing 100 of the present embodiment is divided into two parts (a first sub-shell 110 and a second sub-shell 120) along its circumference, and the two parts are rotatably connected, so that the first sub-shell 110 and the second sub-shell 120 can rotate around the rotation connection point to open or close the casing 100, thereby reducing the difficulty of opening and closing the casing 100.

Among them, when the first sub-shell 110 and the second sub-shell 120 are rotated to fully open the interior of the casing 100, on the one hand, it is convenient to assemble the movable assembly 220 and the stator assembly 210, and on the other hand, it is also convenient to maintain the movable assembly 220 and the stator assembly 210, and at the same time, it can also avoid the movable assembly 220 and the stator assembly 210 from colliding with the casing 100 during the assembly process to a certain extent; when the first sub-shell 110 and the second sub-shell 120 are rotated to fully close the interior of the casing 100, the casing 100 can be used to support and protect the movable assembly 220 and the stator assembly 210.

It should be noted that when the casing 100 is formed into a cylindrical outer shell, the above-mentioned setting can realize the separation of the casing 100 into a first sub-shell 110 and a second sub-shell 120 in the radial direction of the casing 100, so as to reduce the difficulty of assembling the casing 100 and reduce the difficulty of matching the movable sub-assembly 220 and the stator assembly 210 with the casing 100.

In some embodiments, in combination with FIGS. 9, 10, 11 and 12, the first sub-housing 110 is provided with a first connecting portion 111 protruding therefrom, the second sub-housing 120 is provided with a second connecting portion 121 protruding therefrom, and the first connecting portion 111 and the second connecting portion 121 are rotatably connected. Here, it means that the first sub-housing 110 is provided with a first connecting portion 111 and the first connecting portion 111 protrudes from the first sub-housing 110, and the second sub-housing 120 is provided with a second connecting portion 121 and the second connecting portion 121 protrudes from the second sub-housing 120, so as to facilitate the rotatable connection between the first connecting portion 111 and the second connecting portion 121, so as to reduce the difficulty of connecting the first connecting portion 111 and the second connecting portion 121.

At the same time, after the first connecting portion 111 and the second connecting portion 121 are rotationally connected, the first sub-shell 110 and the second sub-shell 120 can be rotationally connected. In this way, during the assembly process of the second sub-shell 120 and the first sub-shell 110, the second sub-shell 120 and the first sub-shell 110 can be rotationally connected first. After the connection is in place, at least one of the second sub-shell 120 and the first sub-shell 110 is rotated to form the housing 100, thereby reducing the difficulty of assembling the housing 100.

In some embodiments, as shown in FIG. 5 and FIG. 6 , the electromagnetic actuator 1000 further includes a rotating shaft 140. The first sub-housing 110 and the second sub-housing 120 are both provided with shaft holes, and the rotating shaft 140 is disposed in the shaft holes so that the first sub-housing 110 and the second sub-housing 120 can move relative to each other. Thus, the first sub-housing 110 and the second sub-housing 120 can be connected in rotation, and the connection difficulty of the first sub-housing 110 and the second sub-housing 120 can be reduced.

In some embodiments, in combination with Figures 5-12, the first connecting portion 111 includes a plurality of first connecting lugs 1111, and the plurality of first connecting lugs 1111 are arranged at intervals. The second connecting portion 121 includes a plurality of second connecting lugs 1211, and the plurality of second connecting lugs 1211 are arranged at intervals. The plurality of first connecting lugs 1111 and the plurality of second connecting lugs 1211 are arranged alternately. The first connecting lug 1111 is provided with a first connecting hole 1112, and the second connecting lug 1211 is provided with a second connecting hole 1212. The rotating shaft 140 is used to penetrate the plurality of first connecting holes 1112 and the plurality of second connecting holes 1212, so as to facilitate the use of the rotating shaft 140 to realize the rotational connection between the first connecting lug 1111 and the second connecting lug 1211, that is, to realize the rotational connection between the first sub-shell 110 and the second sub-shell 120.

It should be noted that the staggered arrangement mentioned above can be understood as that in the left-right direction shown in Figure 5, the first connecting lug 1111 and the second connecting lug 1211 are not arranged opposite each other, so that multiple first connecting lugs 1111 and multiple second connecting lugs 1211 are arranged alternately, so that after the first sub-shell 110 and the second sub-shell 120 are rotated and docked, the first connecting lug 1111 and the second connecting lug 1211 can be arranged opposite each other in the front-to-back direction of the casing 100. The front-to-back direction mentioned here intersects with the up-down direction and the left-to-right direction in Figure 5, so that the rotating shaft 140 can be simultaneously penetrated by multiple first connecting lugs 1111 and multiple second connecting lugs 1211, so as to facilitate the use of the rotating shaft 140 to realize the connection of multiple first connecting lugs 1111 and multiple second connecting lugs 1211, that is, to realize the rotational connection of the first connecting part 111 and the second connecting part 121.

Among them, the left and right direction shown in Figure 5 can also be understood as the docking direction of the first sub-shell 110 and the second sub-shell 120, that is, during the docking process of the first sub-shell 110 and the second sub-shell 120, the multiple first connecting lugs 1111 and the multiple second connecting lugs 1211 are staggered, so that after the first sub-shell 110 and the second sub-shell 120 are docked, the first connecting lugs 1111 and the second connecting lugs 1211 can be arranged opposite to each other in the front-to-back direction of the casing 100. It can be understood that at this time, the axial holes on the first sub-shell 110 and the second sub-shell 120 are arranged opposite to each other in the front-to-back direction.

In summary, the casing 100 of the present embodiment is divided into two parts along its circumference, and the first sub-shell 110 and the second sub-shell 120 are connected by using the rotating shaft 140, the first connecting part 111 and the second connecting part 121, so that the first sub-shell 110 and the second sub-shell 120 can be rotated around the rotating shaft 140 to open or close the casing 100, so that the interior of the casing 100 can be completely opened, which is conducive to the positioning, installation, fixation, maintenance, etc. of the movable assembly 220 and the stator assembly 210 in the casing 100, and relative to the end opening of the casing 100, it can also prevent the movable assembly 220 and the stator assembly 210 from colliding with the casing 100 during the assembly process.

In some embodiments, as shown in FIG6 , in the axial direction of the housing 100, the end of the first sub-housing 110 is rotatably connected to the end of the second sub-housing 120. In other words, one axial end of the first sub-housing 110 is rotatably connected to one axial end of the second sub-housing 120, thereby realizing the rotational cooperation between the first sub-housing 110 and the second sub-housing 120, and reducing the difficulty of assembling the first sub-housing 110 and the second sub-housing 120.

In some embodiments, as shown in Figures 9, 10, 11 and 12, the first connecting portion 111 is disposed at one axial end of the first sub-shell 110, and the second connecting portion 121 is disposed at one axial end of the second sub-shell 120, so that after the first connecting portion 111 and the second connecting portion 121 are rotationally connected, the first sub-shell 110 and the second sub-shell 120 can be rotationally matched, and the end of the first sub-shell 110 and the end of the second sub-shell 120 can be rotationally connected.

Through the above arrangement, during the assembly of the housing 100, one end of the first sub-housing 110 and one end of the second sub-housing 120 can be firstly rotatably connected, and after the connection is in place, the mover assembly 220 and the stator assembly 210 are assembled between the first sub-housing 110 and the second sub-housing 120 (such as 6 ), and then the other end of the first sub-shell 110 and the other end of the second sub-shell 120 are driven to rotate toward each other to achieve the matching connection between the first sub-shell 110 and the second sub-shell 120.

In other embodiments, as shown in FIG8 , one side of the first sub-housing 110 is rotatably connected to one side of the second sub-housing 120 in the circumferential direction of the housing 100. That is, it is not limited to rotatably connecting the end of the first sub-housing 110 and the end of the second sub-housing 120, and one side of the first sub-housing 110 and one side of the second sub-housing 120 in the circumferential direction of the housing 100 can also be rotatably connected, and the rotational cooperation between the first sub-housing 110 and the second sub-housing 120 can also be achieved, thereby reducing the difficulty of assembling the first sub-housing 110 and the second sub-housing 120.

In some embodiments, as shown in Figure 8, the first connecting portion 111 is arranged on one side of the first sub-shell 110 in the circumferential direction, and the second connecting portion 121 is arranged on one side of the second sub-shell 120 in the circumferential direction, so that after the first connecting portion 111 and the second connecting portion 121 are rotatably connected, the first sub-shell 110 and the second sub-shell 120 can be rotatably matched, and one side of the first sub-shell 110 and one side of the second sub-shell 120 can be rotatably connected.

Through the above-mentioned arrangement, as shown in Figure 8, during the assembly of the casing 100, one side of the first sub-shell 110 in the circumferential direction and one side of the second sub-shell 120 in the circumferential direction can be first rotationally connected. After the connection is in place, the movable sub-assembly 220 and the stator assembly 210 are assembled between the first sub-shell 110 and the second sub-shell 120, and then the other side of the first sub-shell 110 in the circumferential direction and the other side of the second sub-shell 120 in the circumferential direction are driven to rotate toward each other to achieve the mating connection between the first sub-shell 110 and the second sub-shell 120.

In some embodiments, the first sub-housing 110 and the second sub-housing 120 are detachably matched. That is, the first sub-housing 110 and the second sub-housing 120 are not only rotatably connected, but also detachably matched, so that the first sub-housing 110 and the second sub-housing 120 can be fixedly connected, so that the relative position of the first sub-housing 110 and the second sub-housing 120 is stable, thereby ensuring the position stability of the housing 100, facilitating the use of the housing 100 to support and protect the mover assembly 220 and the stator assembly 210, so as to extend the service life of the mover assembly 220 and the stator assembly 210, and improve the position stability of the mover assembly 220 and the stator assembly 210.

At the same time, by arranging the first sub-shell 110 and the second sub-shell 120 to be detachably matched, the difficulty of assembling and disassembling the first sub-shell 110 and the second sub-shell 120 can be reduced, so as to reduce the difficulty of assembling and disassembling the casing 100 and facilitate the maintenance of the movable sub-assembly 220 and the stator assembly 210.

In some embodiments, as shown in Figure 6, one of the first sub-shell 110 and the second sub-shell 120 is provided with a third connecting portion 112, and the other is provided with a fourth connecting portion 122 facing the third connecting portion 112, and the first fastener 150 connects the third connecting portion 112 and the fourth connecting portion 122 to make the first sub-shell 110 and the second sub-shell 120 detachable. What is meant here is that when the third connecting portion 112 is provided on the first sub-shell 110, the fourth connecting portion 122 is provided on the second sub-shell 120; when the third connecting portion 112 is provided on the second sub-shell 120, the fourth connecting portion 122 is provided on the first sub-shell 110, so that when the first fastener 150 is connected to the third connecting portion 112 and the fourth connecting portion 122, the detachable cooperation of the first sub-shell 110 and the second sub-shell 120 can be achieved, and while achieving the fixed connection between the first sub-shell 110 and the second sub-shell 120, the relative position of the first sub-shell 110 and the second sub-shell 120 can be stabilized, thereby ensuring the position stability of the casing 100 and reducing the difficulty of assembling the casing 100.

In some embodiments, in combination with Figures 9, 10 and 12, a third connection hole 1121 is provided on the third connection portion 112, a fourth connection hole 1221 is provided on the fourth connection portion 122, and the first fastener 150 connects the third connection hole 1121 and the fourth connection hole 1221, thereby achieving a fixed connection between the third connection portion 112 and the fourth connection portion 122.

Optionally, the first fastener 150 may be a fastening bolt, a fastening screw, or a rivet.

Optionally, in combination with Figures 5, 6 and 8, a plurality of third connecting parts 112 are provided on the first sub-shell 110, and the plurality of third connecting parts 112 are respectively located on the side wall and the end wall of the first sub-shell 110, and a plurality of fourth connecting parts 122 are provided on the second sub-shell 120 that are opposite to the third connecting parts 112, so that when the first fastener 150 connects the third connecting parts 112 and the fourth connecting parts 122, the side walls and the end walls of the first sub-shell 110 and the second sub-shell 120 can be detachably matched to improve the connection strength between the first sub-shell 110 and the second sub-shell 120, thereby stabilizing the relative positions of the first sub-shell 110 and the second sub-shell 120.

In some embodiments, as shown in FIG. 7 , the housing 100 is provided with a first avoidance through hole 160 , which is connected to the accommodating cavity 130 , and is suitable for avoiding the center rod 300 . A cylindrical bearing 170 is provided in the first avoidance through hole 160 . Among them, by setting a first avoidance through hole 160 that avoids the center rod 300 and is connected to the accommodating cavity 130, it can be ensured that the center rod 300 can extend into the accommodating cavity 130 through the first avoidance through hole 160; by setting a cylindrical bearing 170 in the first avoidance through hole 160, when the center rod 300 moves relative to the accommodating cavity 130, the bearing 170 can be used to guide the center rod 300 to ensure the position accuracy of the center rod 300 when it moves, and at the same time, it can also avoid the center rod 300 from contacting the hole wall of the first avoidance through hole 160 during the movement, thereby avoiding interference between the center rod 300 and the hole wall of the first avoidance through hole 160, so that the center rod 300 can accurately move relative to the accommodating cavity 130.

At the same time, by providing the bearing 170, it is more conducive to ensuring that the air gap between the permanent magnet and the coil is maintained within a reasonable designed range, ensuring the stability of the system structure and improving the system's ability to resist side suction.

It should be noted that, since the first avoidance through hole 160 is formed on the housing 100, during the processing of the first avoidance through hole 160, technical problems such as low smoothness of the hole wall of the first avoidance through hole 160 and poor positional accuracy of the first avoidance through hole 160 are likely to occur. At this time, if the center rod 300 is directly matched with the first avoidance through hole 160, the center rod 300 is likely to interfere with the first avoidance through hole 160 during movement. Therefore, in this embodiment, a cylindrical bearing 170 is arranged in the first avoidance through hole 160. In this way, while the bearing 170 is used to guide the center rod 300, interference between the center rod 300 and the hole wall of the first avoidance through hole 160 during movement can be avoided, so as to ensure the positional accuracy of the center rod 300 during movement.

It should also be noted that the movement of the central rod 300 relative to the accommodating cavity 130 may be movement or rotation.

Optionally, the bearing 170 is detachably disposed in the first avoidance through hole 160 , so that the bearing 170 can be easily processed separately to ensure the structural accuracy of the bearing 170 , thereby ensuring the guiding performance of the bearing 170 .

In some embodiments, as shown in Figures 15 and 16, a protrusion 171 is provided on the outer periphery of the bearing 170, and the protrusion 171 is matched and connected in the first avoidance through hole 160 to achieve the matching connection between the bearing 170 and the first avoidance through hole 160, so as to facilitate the use of the bearing 170 to guide the center rod 300, and make the structure of the bearing 170 simple and easy to install, and at the same time, there is no need to add an additional installation and fixing structure to fix the bearing 170.

In some embodiments, as shown in Figures 6 and 14, a stator assembly 210 is provided on the center rod 300, so that when the center rod 300 is extended into the accommodating cavity 130, the stator assembly 210 can be arranged in the accommodating cavity 130, so that the stator assembly 210 and the mover assembly 220 can cooperate with each other, thereby ensuring the working performance of the electromagnetic actuator 1000.

At the same time, by arranging the stator assembly 210 on the center rod 300 and the mover assembly 220 in the housing 100, an electromagnetic solution with a permanent magnet placed outside and a coil assembly placed inside can be formed. Under the constraints of limited space, a larger air gap diameter can be obtained, thereby providing greater active thrust.

It should be noted that, since the casing 100 of the present embodiment is divided into a first sub-shell 110 and a second sub-shell 120 along its circumferential direction, when the casing 100 is used on the electromagnetic actuator 1000, since the stator assembly 210 needs to be divided into two halves when it is arranged on the first sub-shell 110 and the second sub-shell 120, magnetic flux lines cannot be generated. Therefore, when the casing 100 is used on the electromagnetic actuator 1000, the stator assembly 210 is arranged on the center rod 300, and the mover assembly 220 is arranged on the first sub-shell 110 and the second sub-shell 120 and divided into two parts; when the casing 100 is used on a rotating motor, since the directions of the stator assembly 210 are different, the stator assembly 210 can be arranged on the first sub-shell 110 and the second sub-shell 120 and divided into two parts, or it can be arranged on the center rod 300.

In some embodiments, as shown in FIG6, FIG9 and FIG11, the first sub-housing 110 is provided with a first avoidance groove 113, and the second sub-housing 120 is provided with a second avoidance groove 123, and the first avoidance groove 113 and the second avoidance groove 123 cooperate to define a first avoidance through hole 160. In this way, the first avoidance through hole 160 communicating with the accommodating cavity 130 is formed on the housing 100, and the molding difficulty of the first avoidance through hole 160 and the matching difficulty of the bearing 170, the center rod 300 and the first avoidance through hole 160 are reduced, thereby improving the assembly efficiency of the housing 100.

At the same time, the above arrangement can also facilitate the assembly of the stator assembly 210 on the center rod 300 into the accommodating cavity 130 .

In summary, it can be understood that after the housing 100 is divided into the first sub-housing 110 and the second sub-housing 120 along its circumferential direction, the center dividing plane of the housing 100 is a plane passing through the axis of the bearing 170 .

It should be noted that, for a cylindrical motor housing, the center dividing plane can divide the cylindrical motor housing into two symmetrical parts; for motor housings of other shapes (such as square, pentagonal, etc.), the center dividing plane can divide the housing 100 into two parts but they are asymmetrical.

That is, when the housing 100 is formed into a cylindrical motor housing, the first sub-housing 110 and the second sub-housing 120 are generally symmetrical in structure; when the housing 100 is formed into a motor housing of other shapes, the first sub-housing 110 and the second sub-housing 120 are generally asymmetrical in structure.

In some embodiments, as shown in Fig. 6 and Fig. 7, the housing 100 further includes a guide rod 400, and the other of the movable subassembly 220 and the stator subassembly 210 cooperates with the guide rod 400. This prevents the movable subassembly 220 and the other of the stator subassembly 210 from deviating during the movement, that is, it ensures that the movable subassembly 220 and the other of the stator subassembly 210 can move relative to each other in a predetermined direction, and ensures the accuracy of the movement of the other of the movable subassembly 220 and the stator subassembly 210, so that to a certain extent, the relative axial distance between the housing 100 and the movable subassembly 220 and the other of the stator subassembly 210 remains unchanged during the mutual movement.

In some embodiments, as shown in FIG. 7 , a guide hole 310 is provided at one end of the center rod 300 located in the accommodating cavity 130 , and the guide rod 400 is movably matched with the guide hole 310 so as to utilize the guide rod 400 to guide the moving direction of the center rod 300 and ensure the accuracy of the movement of the center rod 300 .

In some embodiments, as shown in FIG7 , the guide rod 400 is disposed on the rotating shaft 140. Here, it means that when the end of the first sub-housing 110 and the end of the second sub-housing 120 are rotatably connected, the guide rod 400 is disposed on the rotating shaft 140 to achieve a fixed connection between the end of the guide rod 400 and the housing 100, reduce the difficulty of matching the guide rod 400 with the housing 100, thereby facilitating the use of the housing 100 to support the guide rod 400 and improve the position stability of the guide rod 400.

In some embodiments, as shown in combination with FIG. 7 and FIG. 13 , a through hole 411 is provided on the guide rod 400 , and the rotating shaft 140 is passed through the through hole 411 , so that the guide rod 400 is arranged on the rotating shaft 140 .

In summary, the first sub-shell 110, the second sub-shell 120 and the guide rod 400 of the present embodiment are connected together by the rotating shaft 140, and the three can rotate relative to each other around the rotating shaft 140. When the housing 100 is specifically assembled, the rotating shaft 140 is first passed through the plurality of first connecting lugs 1111, the plurality of second connecting lugs 1211 and the end of the guide rod 400 in sequence to achieve the rotational cooperation of the first sub-shell 110, the second sub-shell 120 and the guide rod 400, and then the bearing 170 is sleeved on the center rod 300, and the center rod 300 is sleeved on the guide rod 400, and then the guide rod 400, the bearing 170 and the center rod 300 are rotated around the rotating shaft 140 to make them close to one of the first sub-shell 110 or the second sub-shell 120. And ensure that the bearing 170 is engaged in the third avoidance groove 114 or the fourth avoidance groove 124, and then control the other of the first sub-shell 110 or the second sub-shell 120 to rotate around the rotating shaft 140 to make the first sub-shell 110 and the second sub-shell 120 fit together, and finally use the first fastener 150 to connect the first sub-shell 110 and the second sub-shell 120 to achieve a fixed connection between the first sub-shell 110 and the second sub-shell 120. In the above connection process, the stator assembly 210 on the center rod 300 can be completely avoided from contacting the movable sub-assembly 220 on the first sub-shell 110 and the second sub-shell 120, thereby avoiding damage to the movable sub-assembly 220 and the stator assembly 210 and extending the service life of the movable sub-assembly 220 and the stator assembly 210.

In addition, the above-mentioned arrangement can also enable the guide rod 400 and the housing 100 to form a split and detachable design, which is more conducive to the installation and fixation of the movable subassembly 220 on the inner circumferential surface of the housing 100 without losing the coaxiality of the guide rod 400 and the housing 100. At the same time, it is also convenient to process the guide rod 400 separately to ensure the smoothness of the surface of the guide rod 400, thereby ensuring the guiding performance of the guide rod 400.

In some embodiments, as shown in FIG. 6 , FIG. 7 and FIG. 8 , at least part of the structure of the guide rod 400 extends out of the accommodating cavity 130, and the through hole 411 is provided on the part of the structure of the guide rod 400 extending out of the accommodating cavity 130. That is, the ends of the guide rod 400 extend out of the first sub-shell 110 and the second sub-shell 120, and the ends of the guide rod 400 are connected to the first sub-shell 110 and the second sub-shell 120. This realizes the fixed connection between the guide rod 400 and the housing 100, so that the housing 100 is conveniently used to support the guide rod 400, and the position stability of the guide rod 400 is improved, so as to ensure the working performance of the guide rod 400, and facilitate the use of the guide rod 400 to guide the moving direction of the center rod 300.

At the same time, by extending the end of the guide rod 400 out of the first sub-shell 110 and the second sub-shell 120, the guide rod 400 and the shell 100 can be connected outside the shell 100 to reduce the difficulty of connecting the guide rod 400 and the shell 100, that is, to reduce the difficulty of matching the guide rod 400.

In some embodiments, as shown in Figure 7, the housing 100 is provided with a second avoidance through hole 161, which is connected to the accommodating cavity 130. The second avoidance through hole 161 is used to avoid the guide rod 400, so that the end of the guide rod 400 can extend out of the first sub-shell 110 and the second sub-shell 120 and be connected to the first sub-shell 110 and the second sub-shell 120, so as to reduce the difficulty of connecting the guide rod 400 and the housing 100.

Optionally, as shown in Figures 6, 8, 10 and 12, the first sub-housing 110 is provided with a third avoidance groove 114, the second sub-housing 120 is provided with a fourth avoidance groove 124, and the third avoidance groove 114 and the fourth avoidance groove 124 cooperate to define a second avoidance through hole 161. In this way, the second avoidance through hole 161 communicating with the accommodating cavity 130 is formed on the housing 100, and the molding difficulty of the second avoidance through hole 161 and the matching difficulty of the guide rod 400 and the second avoidance through hole 161 are reduced, thereby improving the assembly efficiency of the housing 100.

Optionally, as shown in Figures 7 and 13, a guide protrusion 430 is provided on the guide rod 400, and the guide protrusion 430 is matched and connected in the second avoidance through hole 161 to achieve the matching connection between the guide rod 400 and the second avoidance through hole 161, and to position the guide rod 400 to ensure the position stability of the guide rod 400.

Here, it means that when one side of the first sub-housing 110 and one side of the second sub-housing 120 are rotatably connected, the end of the guide rod 400 is connected to the axial end of the first sub-housing 110 and the second sub-housing 120, so that the first sub-housing 110 and the second sub-housing 120 are rotatably connected, and the guide rod 400 can also be effectively matched with the center rod 300, so that the moving direction of the center rod 300 is guided by the guide rod 400.

In some embodiments, as shown in Figure 8, in the circumferential direction of the casing 100, one side of the first sub-shell 110 and one side of the second sub-shell 120 are rotatably connected, a mounting plate 420 is set at the end of the guide rod 400, and a fifth connecting hole 421 is provided on the mounting plate 420, and a sixth connecting hole 180 facing the fifth connecting hole 421 is provided on the first sub-shell 110 and the second sub-shell 120, and a second fastener connects the fifth connecting hole 421 and the sixth connecting hole 180 so that the guide rod 400 is fixedly connected to the first sub-shell 110 and the second sub-shell 120, so as to facilitate the use of the casing 100 to support the guide rod 400, improve the position stability of the guide rod 400, and thereby ensure the working performance of the guide rod 400.

Optionally, the second fastener may be a fastening bolt, a fastening screw or a rivet.

In summary, the first sub-shell 110 and the second sub-shell 120 of the present embodiment are connected together by the rotating shaft 140, and the two can rotate relative to each other around the rotating shaft 140. When the housing 100 is specifically assembled, the rotating shaft 140 is first passed through the plurality of first connecting lugs 1111 and the plurality of second connecting lugs 1211 in sequence to achieve the rotational cooperation of the first sub-shell 110 and the second sub-shell 120, and then the center rod 300 is disposed in one of the first sub-shell 110 and the second sub-shell 120, and the bearing 170 is sleeved on the center rod 300 and the center rod 300 is sleeved on the guide rod 400, and then the other of the first sub-shell 110 and the second sub-shell 120 is rotated around the rotating shaft 140 so that it is close to the first sub-shell 110 or the second sub-shell 120. One of the second sub-shells 120, and ensure that the bearing 170 fits in the third avoidance groove 114 and the fourth avoidance groove 124, so that the first sub-shell 110 and the second sub-shell 120 fit together, and finally use the first fastener 150 to connect the first sub-shell 110 and the second sub-shell 120, and use the second fastener to connect the guide rod 400 to achieve a fixed connection between the first sub-shell 110 and the second sub-shell 120. In the above-mentioned connection process, the stator assembly 210 on the center rod 300 can also be completely avoided from contacting the movable sub-assembly 220 on the first sub-shell 110 and the second sub-shell 120, thereby avoiding damage to the movable sub-assembly 220 and the stator assembly 210, and extending the service life of the movable sub-assembly 220 and the stator assembly 210.

In some embodiments, the electromagnetic actuator 1000 of this embodiment is formed as a cylindrical linear motor, which has a relatively closed structure, good sealing and no unilateral magnetic pulling force, so as to ensure the working performance of the electromagnetic actuator 1000.

It should be noted that when the electromagnetic actuator 1000 is formed as a cylindrical linear motor, the first sub-shell 110 and the second sub-shell 120 of the housing 100 are both formed as cylindrical, so that the first sub-shell 110 and the second sub-shell 120 can cooperate to form a complete cylindrical motor housing.

In some embodiments, as shown in FIG. 7 , a spring 600 is disposed on the electromagnetic actuator 1000 , and the spring 600 is used to provide a portion of the damping force and withstand a portion of the vibration impact, so as to improve the working performance of the electromagnetic actuator 1000 , thereby ensuring the comfort of the vehicle 20000 .

Optionally, as shown in FIG7 , the electromagnetic actuator 1000 is further provided with an upper support 500 and a mounting seat 191, the upper support 500 is connected to the side of the center rod 300 away from the accommodating cavity 130, the mounting seat 191 is connected to the outer peripheral wall of the housing 100, and a receiving space for accommodating the spring 600 is formed between the upper support 500 and the mounting seat 191. The spring 600 is placed in the receiving space to achieve the upper support 500 and the mounting seat 191 to cooperate and fix the spring 600, so that when the electromagnetic actuator 1000 is applied to the suspension system 10000 of the vehicle 20000, when the vehicle 20000 is excited by the road surface and the center rod 300 and the housing 100 move relatively, the spring 600 can be used to achieve buffering and vibration absorption, and the spring 600 can also play a certain damping role, thereby improving the vibration reduction effect of the electromagnetic actuator 1000, thereby improving the comfort of the vehicle 20000.

In some embodiments, as shown in Figure 7, the spring 600 is arranged between the upper support 500 and the mounting seat 191, and the upper end of the spring 600 abuts against the upper support 500, and the lower end of the spring 600 abuts against the mounting seat 191. In this way, during the relative movement of the center rod 300 and the housing 100, the spring 600 can be compressed or stretched, so that the spring 600 can provide part of the damping force and withstand part of the vibration impact, thereby improving the comfort of the vehicle 20000.

In some embodiments, as shown in Figure 7, a bushing 700 is provided on the side of the center rod 300 away from the accommodating cavity 130, the bushing 700 is connected to the upper support 500, and buffer blocks 800 are provided on the opposite sides of the upper support 500 and the mounting seat 191, and the spring 600 is arranged between the two buffer blocks 800.

In some embodiments, as shown in FIG. 17 , FIG. 18 , FIG. 19 and FIG. 20 , the mover assembly 220 is connected to the housing 100, and an elastic stopper 1015 is provided between the housing 100 and the stator assembly 210, and the elastic stopper 1015 respectively stops against the housing 100 and the stator assembly 210. This ensures that the electromagnetic actuator 1000 can buffer the vibration of the stator assembly 210 during operation, prolong the service life of the stator assembly 210, and reduce the noise generated by the electromagnetic actuator 1000 during operation.

In some embodiments, the elastic stopper 1015 is formed as a spring 600 and/or a buffer pad. Here, it means that the elastic stopper 1015 is formed as a spring 600; or, the elastic stopper 1015 is formed as a buffer pad; or, the elastic stopper 1015 is formed as a spring 600 and a buffer pad, so that the elastic stopper 1015 can buffer the vibration of the stator assembly 210, extend the service life of the stator assembly 210, and reduce the noise generated by the electromagnetic actuator 1000 during operation.

It should be noted that the specific implementation forms of the elastic limiter 1015 of this embodiment include but are not limited to rubber pads, polyurethane pads, spiral springs, leaf springs, coil springs and other elastic parts. This embodiment has no restrictions on the number and layering of the elastic limiter 1015. For example, the use of multi-layer buffer pads or circumferentially arranged multiple springs are all within the scope of embodiments that can be implemented in this embodiment.

In some embodiments, as shown in FIG. 20 , the elastic limit member 1015 is a coil spring, and the coil spring is arranged between the housing 100 and the stator assembly 210. In actual use, in order to buffer the movement of the stator assembly 210, it is necessary to ensure that the coil spring is in a compressed state after assembly. Therefore, the compression amount of the coil spring can be ensured by pressing the end cover 1012.

In some embodiments, as shown in Figures 17, 10 and 20, the stator assembly 210 is located inside the casing 100 and distributed along the inner radial circumference of the casing 100. The elastic limiter 1015 is located at the lower part of the stator assembly 210 and the upper side of the end cover 1012.

Among them, the stator assembly 210 is composed of a multi-layer magnet assembly, a layer of magnets forms a complete circular ring, all layers of magnets are pasted to the inner wall of the casing 100, and an elastic limiter 1015 is arranged at the bottom of the lowest layer of magnets, and the lower end of the elastic limiter 1015 is connected to the top of the stopper of the end cover 1012. Because the elastic limiter 1015 has a certain elasticity, it can ensure that during the operation of the electromagnetic actuator 1000, the elastic limiter 1015 can buffer the vibration of the magnet.

It should be noted that the size of the elastic limiter 1015 is not fixed and can be adjusted according to the size of the electromagnetic actuator 1000, which has the advantage of high adaptability.

At the same time, the elastic limiting member 1015 of the present embodiment can integrate the function of the sealing module to seal the gap between the end cover 1012 and the housing 100 .

In some examples, during the assembly process, glue is first applied to the outer surface of the stator assembly 210, and then the stator assembly 210 is layered along the axial direction of the electromagnetic actuator 1000. The stator assembly 210 is assembled into the housing 100 . After the stator assembly 210 at the bottom is assembled, the elastic limiter 1015 is assembled, and finally the end cover 1012 is assembled. When the elastic limiter 1015 is a coil spring, the coil spring can be pre-compressed.

It should also be noted that the pre-stress of the helical spring of this embodiment should not be too large to avoid excessive pressure on the magnet. During implementation, the pre-stress can be controlled by the height of the extending portion 1014 on the end cover 1012.

In some embodiments, two adjacent sub-housings 101 of the plurality of sub-housings 101 are rotatably connected. This means that no matter whether the plurality of sub-housings 101 are arranged relative to each other in the circumferential direction of the housing 100 or in the axial direction of the housing 100, two adjacent sub-housings 101 are rotatably connected, so as to further reduce the difficulty of assembling the housing 100, and at the same time reduce the difficulty of assembling the mover assembly 220 and the stator assembly 210, and to a certain extent avoid collision between the mover assembly 220 and the stator assembly 210 and the housing 100 during assembly.

In some embodiments, multiple sub-housings 101 are detachably connected. In this way, multiple sub-housings 101 can be fixedly connected, so that the relative positions of the multiple sub-housings 101 are stable, thereby ensuring the position stability of the housing 100, facilitating the use of the housing 100 to support and protect the mover assembly 220 and the stator assembly 210, thereby extending the service life of the mover assembly 220 and the stator assembly 210, and improving the position stability of the mover assembly 220 and the stator assembly 210.

At the same time, by arranging the multiple sub-housings 101 to be detachably matched, the difficulty of assembling and disassembling the multiple sub-housings 101 can be reduced, so as to reduce the difficulty of assembling and disassembling the casing 100 and facilitate maintenance of the mover assembly 220 and the stator assembly 210.

In some embodiments, as shown in combination with FIG. 22 and FIG. 23 , the center rod 300 is provided with a wire passage 330, and the connecting wire 2121 of the winding assembly 212 passes through the wire passage 330 and extends out of the housing 100. Thus, the connecting wire 2121 of the winding assembly 212 is led from the inside of the housing 100 to the outside of the housing 100, so as to facilitate the leading out of the connecting wire 2121 of the winding assembly 212, thereby reducing the difficulty of electrical connection of the winding assembly 212, and at the same time, the center rod 300 can be used to protect the connecting wire 2121, extend the service life of the connecting wire 2121, and improve the safety of the use of the connecting wire 2121.

In some embodiments, a quick-change connector is provided at the end of the electromagnetic actuator 1000 to enable quick plugging and unplugging of the connecting wire 2121 and the electrical control component.

In some embodiments, in combination with Figures 22, 23 and 26, a wire outlet device 230 is provided in the center rod 300, and a wire passing channel 330 is provided in the wire outlet device 230, thereby realizing the setting of the wire passing channel 330 in the center rod 300 and reducing the difficulty of forming the wire passing channel 330.

It should be noted that the overall structure of the electromagnetic actuator 1000 of this embodiment is based on the traditional hydraulic damping shock absorber, in which the intermediate damper is replaced by a linear motor. According to the structural composition of the electromagnetic actuator 1000, it mainly includes a mover assembly 220 (motor assembly), a stator assembly 210 (stator assembly) and an upper support 500, in which the mover assembly 220 and the stator assembly 210 constitute a linear motor, and the connecting line 2121 of the stator assembly 210 is led to the outside of the casing 100 through the center rod 300.

In some examples, the stator assembly 210 is a part of the stator assembly, which is arranged on the inner side of the entire electromagnetic actuator 1000, and includes a connecting wire 2121, a wire outlet device 230, a detection module 900, a center rod 300, a first limit piece 380, a core assembly 211, a winding assembly 212, a guide bearing 840, a limit nut 850, a bearing 170 and an assembly nut 830, wherein the connecting wire 2121, the limit nut 850, the guide bearing 840, the first limit piece 380, the wire outlet device 230, the bearing 170 and the assembly nut 830 are all assembled on the center rod 300, and together constitute a central assembly, integrating multiple functions such as limiting, positioning, anti-rotation, heat dissipation, guiding, and wire outlet, and the core assembly 211 and the winding assembly 212 constitute the stator assembly 210.

In some embodiments, the core assembly 211 and the winding assembly 212 are both in an annular shape. The stator assembly 210 is composed of a plurality of core assemblies 211 and winding assemblies 212, which are stacked with one layer of winding assembly 212 on top of another layer of core assembly 211 and are sleeved on the center rod 300, eventually forming a cylindrical shape, which is fixed to the center rod 300 by a limiting nut 850. This design facilitates the manufacturing of the core assembly 211 and the winding of the winding assembly 212. The detection module 900 is fixed on the assembly groove 950 of the center rod 300 to accurately locate the relative position between the mover assembly and the stator assembly, thereby achieving accurate control. The connecting wire 2121 is fixed to the center rod 300 via the wire outlet device 230.

In some embodiments, as shown in FIG24 , the outer peripheral wall of the core assembly 211 is provided with a first reinforcing rib 2012, and a wiring channel is provided inside the first reinforcing rib 2012, and the wiring channel is used to guide the connecting wires 2121 of different phases of the winding assembly 212 to the wire passage 330 of the center rod 300. Here, it means that the wiring channel is provided on the inner side of the first reinforcing rib 2012, and the wiring channel is used to facilitate the leading out of the connecting wires 2121 of the winding assembly 212, thereby reducing the difficulty of electrical connection of the winding assembly 212.

At the same time, the difficulty of forming the wiring channel can be reduced by providing the first reinforcing rib 2012 . The wiring channel can also limit the position of the connecting line 2121 , thereby improving the position stability of the connecting line 2121 .

In some embodiments, the first reinforcing rib 2012 protrudes toward the outer periphery of the core assembly 211 to form a wiring channel on the side of the first reinforcing rib 2012 facing the inner periphery of the core assembly 211 .

In some embodiments, as shown in FIG. 24 , a plurality of slots 2019 and a plurality of first reinforcing ribs 2012 that can constrain the direction of the wire output are evenly distributed on the circumference of the core assembly 211 , and connecting wires 2121 of different phases of the winding assembly 212 are output from designated slots 2019 along the wiring channels therein.

At the same time, according to the principle that the three-phase lines of the same phase must be connected together, the connecting lines 2121 of the same phase of the winding assembly 212 are connected from the same slot 2019, so that the connecting lines 2121 of the same phase can be connected from the outside of the core assembly 211 from top to bottom (as shown in Figure 24), the tool operation space is not restricted, and problems can be easily and intuitively found during subsequent maintenance, thereby reducing maintenance costs.

It should be noted that since the slot 2019 limits the wire output direction, and the core assembly 211 and the center rod 300 have cylindrical pins to limit the core assembly 211 from rotating around the center rod 300, the connecting wire 2121 of the winding assembly 212 is relatively fixed, with a small position deviation and a reliable connection.

In some embodiments, in combination with Figures 22, 23, 24 and 25, the three connecting wires 2121 respectively pass through the three wire passing channels 330 on the wire outlet device 230, and the three outlets of the three wire passing channels 330 are evenly distributed in the circumferential direction. Three wire outlets 311 are provided on the center pole 300. The three outlets of the wire passing channels 330, the three wire outlets 311 and the three slots 2019 correspond one to one. During assembly, the wire outlet device 230 is assembled to the center pole 300, and the three connecting wires 2121 pass through the wire outlet device 230, the wire outlets 311 and are connected to the winding assembly 212.

Through the above arrangement, the connecting wire 2121 comes out from the outside of the core assembly 211 and then passes through the inner side of the center rod 300 and reaches the outside of the casing 100 through the wire channel 330. The wire is fixed in the whole process, wherein the wire channel 330 plays a role in fixing and protecting the connecting wire 2121, which effectively solves the problem of the risk of extrusion and scratching in the prior art.

In some embodiments, as shown in FIG. 22 , a first stopper 380 is sleeved on the top of the center rod 300 , and the first stopper 380 and the outlet of the center rod 300 jointly fix the connecting line 2121 .

In some embodiments, the first limiter 380 is made of rubber, which can buffer the impact of surrounding components on the connecting line 2121 under extreme working conditions, thereby protecting the connecting line 2121 and ensuring the reliability of the electrical system.

In this embodiment, the moving subassembly of the electromagnetic actuator 1000 is arranged outside the entire structure, including: a bearing 170, a housing 100, a moving subassembly 220, The second stopper 390, the guide rod 400 and the mounting bracket 192. The mounting bracket 192 is assembled to the wheel end and connected to the housing 100 by a plurality of bolts, and together they form a closed operating environment inside the electromagnetic actuator 1000. The guide rod 400 plays a guiding role. The second stopper 390 is sleeved on the guide rod 400, and can buffer the impact of the mover assembly 220 on the stator assembly 210 under extreme working conditions, thereby protecting the stator assembly 210 well. The mover assembly 220 is evenly distributed on the inner side of the housing 100 to provide a fixed magnetic field. The housing 100 mainly plays a protective role. The local raised features on the housing 100 (such as: the mounting seat 191 and the second reinforcing rib 195) mainly play the role of supporting the spring 600 and overall heat dissipation.

Through the above arrangement, during the movement of the electromagnetic actuator 1000, the mover assembly 220 moves axially up and down along the center line through the bearing 170, the guide bearing 840, the housing 100 and the mounting bracket 192 and the center rod 300. Since the entire interior of the casing 100 is sealed and the casing 100 is moving, the winding assembly 212 needs to pass through the center rod 300 to reach the outside of the casing 100 when it is output, and the outer side of the upper end of the center rod 300 has relative movement with the bearing 170, and the inner side of the lower end is embedded with a guide bearing 840, and the guide bearing 840 has relative movement with the mounting bracket 192. Therefore, as shown in Figure 24, the winding assembly 212 is sleeved under the center rod 300 and the winding assembly 212 is output from the outside, avoiding the relative movement area between the bearing 170 and the mounting bracket 192 under the center rod 300, and the connecting wire 2121 passes through the center rod 300 and reaches the outside of the casing 100 through the output device 230, avoiding the relative movement area between the upper part of the center rod 300 and the bearing 170. This design prevents the connecting wire 2121 from being squeezed or scratched during operation.

In some embodiments, a tower top is provided above the electromagnetic actuator 1000, and the tower top includes an upper support 500, an assembly nut 830, a spring 600, a dust cover 820, and a cooling structure 810. The electromagnetic actuator 1000 is assembled to the tower top by cooperating with the assembly nut 830 through the first threaded section 831 on the center rod 300, and the tower top is fixed to the vehicle body, and the center rod 300 passes through the middle of the upper support 500, and the connecting line 2121 also passes through the vehicle body to reach the front cabin, and is matched with the electronic control end by quickly replacing the connector, so as to connect the motor electronic control, and finally realize the control of the electromagnetic shock absorber.

Among them, the spring 600 can buffer the impact of the road surface, the dust cover 820 can prevent dust from entering the interior of the electromagnetic actuator 1000, the upper support 500 cooperates with the vehicle body to fix one end of the electromagnetic actuator 1000 on the vehicle body, and the cooling structure 810 can perform a heat exchange cycle with the coolant in the center rod 300 to reduce the temperature of the coolant.

In some embodiments, after the winding assembly 212 and the core assembly 211 are assembled to the center rod 300, the limit nut 850 and the second threaded segment 851 cooperate to thread the core assembly 211 onto the center rod 300. This design ensures that the entire core assembly 211 is fixed to the center rod 300 as designed.

In summary, the wire output structure of the electromagnetic actuator 1000 of this embodiment utilizes the relative relationship of the surrounding components and is cleverly designed to solve the problem of wire output difficulties. It has the advantages of safety and reliability, easy disassembly and assembly, and compact space design.

In some embodiments, as shown in FIGS. 21 to 25 , the center rod 300 is provided with a first anti-rotation portion 370, and the housing 100 is provided with a second anti-rotation portion, and the first anti-rotation portion 370 and the second anti-rotation portion cooperate to limit the rotational freedom of the center rod 300. This prevents the center rod 300 and the housing 100 from relatively large rotation, so as to ensure that the center rod 300 and the housing 100 can effectively move relative to each other, and ensure the working performance of the electromagnetic actuator 1000.

In some embodiments, as shown in FIGS. 21 to 25 , the first anti-rotation portion 370 is a long groove extending along the axial direction of the center rod 300, and the second anti-rotation portion is fixed to the housing 100 and extends into the first anti-rotation portion 370. Thus, the purpose of limiting the rotational freedom of the center rod 300 by cooperating with the first anti-rotation portion 370 and the second anti-rotation portion is achieved, so that the center rod 300 and the housing 100 are prevented from rotating relative to each other, and the working performance of the electromagnetic actuator 1000 is ensured.

In some embodiments, as shown in Figure 21, an anti-rotation hole 193 is provided on the housing 100, and the second anti-rotation part is an anti-rotation column. The anti-rotation column passes through the anti-rotation hole 193 and extends into the first anti-rotation part 370 to achieve the cooperation between the first anti-rotation part 370 and the second anti-rotation part, thereby facilitating limiting the rotational freedom of the center rod 300.

In some embodiments, the anti-rotation column is fixed to the anti-rotation hole 193 to ensure the position stability of the anti-rotation column, thereby facilitating the use of the first anti-rotation portion 370 and the second anti-rotation portion to cooperate to limit the rotational freedom of the center rod 300 .

In some embodiments, as shown in FIGS. 27 to 35 , the winding assembly 212 has a first outlet 2018, and at least a portion of the first outlet 2018 is located between the core assembly 211 and the housing 100. This allows the outlet of the wires from the outside of the winding assembly 212, thereby reducing the difficulty of outlet of the winding assembly 212 and the difficulty of arranging the connecting wires 2121.

In addition, the above arrangement frees up space inside the core assembly 211, making cooling design more convenient.

In some embodiments, the first outlet terminal 2018 is connected to the connecting wire 2121 to ensure the working performance of the winding assembly 212 .

It should be noted that the electromagnetic actuator 1000 of the present embodiment belongs to the suspension system 10000 of the vehicle 20000, replaces the conventional vehicle shock absorber, and is installed in the position of the conventional vehicle shock absorber. Its main function is to reduce the vibration transmitted by the road surface and control the energy flow, thereby improving the comfort and energy utilization of the whole vehicle. Compared with the conventional shock absorber, it has a complete linear motor structure, can perform linear motion, and replaces the hydraulic damping structure of the conventional shock absorber.

Among them, the output line structure is for the linear motor part in the electromagnetic actuator 1000. This linear motor is an electric motor in which the mover component 220 and the stator component 210 can perform linear displacement relative to each other, and it includes the mover component and stator component in the usual sense of the motor.

In some embodiments, as shown in FIG. 27 to FIG. 35, the electromagnetic actuator 1000 of this embodiment includes an upper support 500, an assembly nut 830, a center rod 300, a connecting wire 2121, a housing 100, a moving subassembly 220, a stator assembly 210, and a mounting bracket 192. Among them, the upper support 500 is locked with the center rod 300 by the assembly nut 830, the connecting wire 2121 includes three phases A, B, and C, the connecting wire 2121, the center rod 300 and the stator assembly 210 constitute the stator assembly of the electromagnetic actuator 1000, the moving subassembly 220 and the housing 100 constitute the moving subassembly of the electromagnetic actuator 1000, and the mounting bracket 192 plays the role of connecting the suspension system 10000.

In some embodiments, in combination with Figures 28 and 29, the core assembly 211 has a tooth slot, the winding assembly 212 is arranged in the tooth slot, and a wire end outlet groove 2015 is opened on the surface of each tooth slot, which is used for the wire end of the winding assembly 212 in each tooth slot to pass through between the core assembly 211 and the housing 100, so that at least part of the structure of the first outlet head 2018 of the winding assembly 212 can be located between the core assembly 211 and the housing 100, so as to realize the outlet of the wire from the outside of the winding assembly 212, thereby reducing the difficulty of outlet of the winding assembly 212 and the difficulty of arranging the connecting wire 2121.

In some embodiments, as shown in FIG. 28 , a groove 20111 is formed on the outer surface of the core assembly 211 for cross-phase connection between the winding assemblies 212 .

Optionally, as shown in Figure 31, the winding assembly 212 includes a first phase winding 21214, a second phase winding 21215 and a third phase winding 21216. The first phase winding 21214 and the first phase winding 21214, the second phase winding 21215 and the second phase winding 21215, and the second phase winding 21216 and the second phase winding 21216 need to connect the first output terminals 2018 at one end to form a series structure. In this embodiment, a groove 20111 is provided on the outer surface of the core assembly 211, which is beneficial to the passage of the first output terminals 2018 between phases. The first output terminals 2018 need not be welded or crimped. The groove 20111 allows the first output terminals 2018 to be connected without obstruction around them, with a large operating space and low implementation difficulty, which is beneficial to mass production.

In some embodiments, as shown in FIG. 30 , a cable groove 2013 is provided on the top of the core assembly 211. When the wiring between the three first outlet terminals 2018 is completed, the final connecting wire 2121 will reach the upper surface of the core assembly 211, and the three-phase wires will be directly buried in the cable groove 2013 on the upper surface to ensure smooth wiring.

In some embodiments, a wire passage 330 is provided on the central rod 300 , and the connecting wire 2121 passes through the wire passage 330 and extends to the outside of the housing 100 .

In some embodiments, as shown in Figures 28 and 32, the wire passage 330 is formed on the outer wall of the center rod 300. In this way, the connecting wire 2121 does not need to pass inside and outside, and fits perfectly with the outer wall of the center rod 300, reducing the connection difficulty of the connecting wire 2121.

In some embodiments, the connection line 2121 can be fixed by gluing, injection molding, or covered with a protective shell to enhance the fit between the connection line 2121 and the center rod 300, and the operation is convenient and the operating space is sufficient.

In some embodiments, in combination with Figures 30 and 32, the cable duct 2013 can be linear, spiral, or curved, and the cable duct 2013 can be one or multiple, multiple cable ducts can merge into one or one cable duct can branch into multiple, all of which are covered by the present embodiment.

In addition, as shown in FIG. 33 , the arrangement order of the first phase winding 21214 , the second phase winding 21215 , and the third phase winding 21216 can be changed arbitrarily, and there are wiring operations.

At the same time, in combination with Figures 27, 34 and 35, the core assembly 211 and the center rod 300 can be either integral or split, and a groove 20111 is provided on the outer surface of the core assembly 211, and the groove 20111 is used for cross-phase connection between the winding assemblies 212.

In summary, the present embodiment buries the connecting wire 2121 in the outer wall of the core assembly 211, which will not interfere with the mover assembly 220. Similarly, it also avoids the inner wall of the upper support 500 and the assembly nut 830, does not affect the assembly of the upper support 500 and the center rod 300, and will not cause interference problems. This makes the lead inspection of the winding assembly 212 convenient and provides ample operating space. It is friendly to the arrangement of the connecting wire 2121, and at the same time frees up the internal space of the core assembly 211 to facilitate cooling design.

In some embodiments, as shown in FIGS. 36 to 40 , the winding assembly 212 has a second outlet 214, and at least part of the second outlet 214 is located between the core assembly 211 and the center rod 300. This allows the outlet of the wire from the inner side of the winding assembly 212, reduces the outlet difficulty of the winding assembly 212, reduces the occupied space of the stator assembly 210, and reduces the molding difficulty of the stator assembly 210.

In some embodiments, the second outlet terminal 214 is connected to the connecting wire 2121 to ensure the working performance of the winding assembly 212 .

In some embodiments, as shown in Fig. 40, the wire passage 330 includes a radial hole 333 and an axial hole 334, and the radial hole 333 is connected with the axial hole 334. Here, it means that the wire passage 330 includes a radial hole 333 extending radially along the electromagnetic actuator 1000 and an axial hole 334 extending axially along the electromagnetic actuator 1000, and the radial hole 333 is connected with the axial hole 334, so that the connecting wire 2121 can effectively pass through the wire passage 330 and extend out, reducing the difficulty of leading out the connecting wire 2121.

In some embodiments, the connecting wire 2121 passes through the axial hole 334 and the radial hole 333 to connect with the second outlet head 214 of the winding assembly 212 to achieve the connection between the second outlet head 214 and the connecting wire 2121 .

In some embodiments, as shown in FIGS. 36 to 40 , the electromagnetic actuator 1000 of this embodiment includes a center rod 300, a core assembly 211, a winding assembly 212, a mover assembly 220, and a housing 100. The center rod 300, the core assembly 211, and the winding assembly 212 together constitute the stator assembly of the electromagnetic actuator 1000, and the mover assembly 220 and the housing 100 together constitute the mover assembly of the electromagnetic actuator 1000.

In some embodiments, the core assembly 211 is pressed or screwed onto the center rod 300, and the winding assembly 212 is wound or placed on the core assembly 211. The three-phase wires of the winding assembly 212 need to be led out from the core assembly 211 and from the top of the center rod 300 to facilitate connection to the motor controller.

In some embodiments, in combination with Figures 38 and 39, a wire end outlet groove 2015 and a radial hole 333 are respectively opened on the core assembly 211, wherein the outer wire end of the winding assembly 212 passes through the wire end outlet groove 2015 from the outermost edge of the core assembly 211 back to the inside to reach the radial hole 333, and the wire is output internally through the radial hole 333, while the inner wire end of the winding assembly 212 can be directly output through the radial hole 333, thereby realizing that at least part of the structure of the second outlet head 214 is set between the core assembly 211 and the center rod 300.

It should be noted that each core assembly 211 and winding assembly 212 on the stator assembly 210 is connected in this way, and the wiring between the wire ends can be performed according to the design of the three-phase line.

It should also be noted that, compared with arranging at least part of the structure of the outlet head of the winding assembly 212 between the core assembly 211 and the casing 100, the present embodiment occupies less space and does not affect the winding space of the winding assembly 212. The slot fill rate is greatly improved compared with the external outlet method, so that more electromagnetic thrust can be obtained in the same space, which ensures that the performance of the electromagnetic actuator 1000 can be greatly improved to a certain extent.

In some embodiments, the wire outlet groove 2015 can be a straight groove or an inclined groove. The number of wire outlet grooves 2015 can be single or multiple according to needs. Multiple wire outlet grooves 2015 are usually evenly distributed to achieve better results. The width of the wire outlet groove 2015 depends on the diameter of the wire used by the electromagnetic actuator 1000. The groove shape of the wire outlet groove 2015 can be an arc mouth, a square mouth, etc.

In some embodiments, the central rod 300 is provided with a connecting rod end outlet groove 331 and a winding segment outlet groove 332 in the axial direction thereof. The rod end outlet groove 331 and the winding segment outlet groove 332 are both provided on the outer wall surface of the central rod 300. The second outlet ends 214 of the winding assembly 212 are all connected to the winding segment outlet groove 332 for alternate wiring operations, and finally the outlet of the winding segment is completed. By providing the rod end outlet groove 331 on the central rod 300, the connecting wire 214 led out from the winding assembly 212 is connected to the winding segment outlet groove 332. 21 can be directly buried in the center pole 300 without changing the overall direction of the outgoing line, so that the outgoing line operation of the connecting line 2121 is convenient and quick, without changing the natural direction of the connecting line 2121, and there is no need to insert the connecting line 2121 into the internal space of the center pole 300 for outgoing line, thus retaining the natural outgoing line state of the three-phase line, causing little damage to the connecting line 2121 itself, effectively improving the durability of the connecting line 2121, and the internal space of the center pole 300 can be vacated for cooling arrangement, thereby improving the performance of the electromagnetic actuator 1000.

It should be noted that if the diameter of the connecting wire 2121 used in the winding assembly 212 is small, the winding segment outlet groove 332 may not be provided, and the wire can be directly outlet along the outer wall of the center rod 300 .

In some embodiments, as shown in FIG. 40 , when the center rod 300 and the core assembly 211 are an integral part, the core assembly 211 includes a plurality of placement grooves 2119 spaced apart along the axial direction of the center rod 300, and the winding assembly 212 is placed in the plurality of placement grooves 2119 to achieve the matching connection between the winding assembly 212 and the core assembly 211, thereby facilitating the formation of the stator assembly 210.

In some embodiments, as shown in FIG. 40 , a wiring space 2011 is provided in the middle of the core assembly 211 , and each slot 2119 is provided with a radial hole 333 communicating with the wiring space 2011 , so as to realize the internal wiring of the winding assembly 212 .

In summary, the present embodiment can effectively improve the slot fill rate of the electromagnetic actuator 1000, thereby improving the performance of the electromagnetic actuator 1000, and burying the connecting wire 2121 in the wall thickness of the center rod 300, does not occupy additional space, and does not change the natural direction of the connecting wire 2121 itself, which is beneficial to extending the service life of the connecting wire 2121 and is convenient and quick to operate.

In some embodiments, in combination with FIG. 67 to FIG. 71, the iron core assembly 211 of this embodiment is mainly used in the linear motor assembly of the electromagnetic suspension. The core assembly 211 belongs to the stator component. On the one hand, it provides support for the coil 2123, the insulating frame 213, etc. On the other hand, it provides a path for the magnetic field generated by the winding assembly 212 and withstands the interaction force generated between the magnetic field and the power magnetic steel. Multiple core assemblies 211 and winding assemblies 212 are stacked, installed and fixed along the axial direction to form a stator assembly 210.

In some embodiments, in combination with Figures 67 and 68, the core assembly 211 includes a third type of core 2110, and the third type of core 2110 includes a support frame 2016 and a support core 2017. Multiple support cores 2017 are assembled and stacked along the circumferential direction to form an annular core, and the annular core and the support frame 2016 form a laminated third type of core 2110.

In some embodiments, in combination with Figures 68, 69 and 70, a protruding structure is set on the inner end of the support core 2017, and a supporting groove is set on the outer cylindrical surface of the support frame 2016. The support groove cooperates with the protruding structure of the support core 2017 to limit and support the root of the support core 2017, thereby ensuring the structural stability of the third type of core 2110.

It should be noted that, as shown in Figure 71, since the coil 2123 and the support core 2017 are axially overlapped, the support frame 2016 is also used to bear the weight of the support core 2017 and the coil 2123. By providing a support groove on the outer cylindrical surface of the support frame 2016, it is also possible to avoid the weight being directly borne by the third type core 2110, thereby improving the reliability of the third type core 2110.

In some embodiments, the support frame 2016 can be designed as an integral structure, or can be designed as an upper and lower split structure connected by fasteners or the like.

In some examples, the support frame 2016 adopts an integral design solution to reduce the difficulty of molding the support frame 2016 and improve the structural strength of the support frame 2016.

In some embodiments, as shown in FIG. 67 , a groove 20111 may be provided at the outer end of the support core 2017 as required for connection between different coils 2123 .

Among them, the position, shape and number of the grooves 20111 can be adjusted according to needs. It is recommended that the shapes of the grooves 20111 of the same third-type iron core 2110 be unified, which can reduce the specifications of the supporting iron core 2017.

In some embodiments, as shown in Figure 69, the support core 2017 is fan-shaped, thin on the inside and thick on the outside. At the same time, under the premise that the support core 2017 meets the requirements of process and use, the thickness of the support core 2017 needs to be as thin as possible, and the shape of the single-piece support core 2017 can be adjusted according to needs, such as setting a groove 20111, but it is necessary to satisfy the matching relationship between the circular support cores 2017 and meet the requirements of the shape of the third type of core 2110, and the specifications of the support core 2017 should be minimized to facilitate production and assembly.

In some embodiments, the support core 2017 is made of magnetic conductive material, and materials with high resistivity are selected as much as possible. Insulating materials are arranged on the left and right sides along the circumferential lamination direction, such as insulating paint. In addition, adhesive materials are also required to be coated. Different support cores 2017 are reliably connected together by adhesive materials. The coating should be as thin as possible while meeting the requirements to reduce the space occupied and avoid excessive reduction in the magnetic permeability of the third type of core 2110.

In some embodiments, if the adhesive material meets the insulation requirements, there is no need to apply the insulating material.

In some embodiments, as shown in Figure 70, the support frame 2016 is annular, and is made of a magnetic conductive material, and preferably a material with a high resistivity. The thickness of the support frame 2016 should be as thin as possible while meeting the process and use requirements.

In some embodiments, as shown in Figure 70, the inner cylindrical surface of the support frame 2016 is provided with a second positioning portion 350, and the center rod 300 is provided with a first positioning portion 340 (the specific structure of the first positioning portion 340 can be seen in Figure 25), and the first positioning portion 340 and the second positioning portion 350 cooperate to make the center rod 300 and the support frame 2016 relatively stationary, thereby achieving circumferential limitation of the third type of iron core 2110 and the center rod 300, preventing the third type of iron core 2110 from rotating around the center rod 300, and ensuring the working performance of the third type of iron core 2110.

In some embodiments, the first positioning portion 340 is formed as a groove provided on the outer peripheral wall of the center rod 300, the second positioning portion 350 is a positioning groove, and the anti-rotation rod 360 is provided between the first positioning portion 340 and the second positioning portion 350. The positions of the center rod 300 and the support frame 2016 are limited so that the center rod 300 and the support frame 2016 are relatively stationary, and the difficulty of limiting the position of the center rod 300 and the support frame 2016 is reduced.

Optionally, the shape and number of the second positioning portions 350 can be set according to requirements.

In some embodiments, as shown in FIG. 71 , the third type of iron core 2110 is stacked and installed axially along the stator center rod, and coils 2123 are placed between the third type of iron cores 2110. After the electromagnetic actuator 1000 is energized, the coils 2123 will be energized to generate a magnetic field. If the current changes, the magnetic field will also change. This change will cause an induced current, i.e., eddy current, to be generated inside the third type of iron core 2110. The eddy current will generate heat loss and reduce the working efficiency of the electromagnetic actuator 1000. By arranging the third type of iron core 2110 to be divided into a plurality of supporting iron cores 2017 along the circumferential direction and performing insulation design between each supporting iron core 2017, the original longer eddy current circuit can be interrupted, so that it can only pass through a smaller cross-section in the narrow circuit of each supporting iron core 2117, thereby increasing the resistance on the eddy current path, reducing the eddy current and thus reducing the eddy current loss. The selection of materials with high resistivity is also for increasing the resistance on the eddy current path.

In some embodiments, since the support frame 2 is a continuous structure in the circumferential direction, eddy current loss will be generated, and therefore, the thickness of the support frame 2 should be as thin as possible.

In some embodiments, as shown in FIGS. 72 to 118 , the electromagnetic actuator 1000 further includes a wiring assembly 2113, and the coils 2123 of the same phase arranged at intervals in the axial direction of the center rod 300 are electrically connected through the wiring assembly 2113. Thus, the electrical connection of the coils 2123 of the same phase is achieved, and the difficulty of the electrical connection of the coils 2123 of the same phase is reduced.

In some embodiments, as shown in FIGS. 77-86 , the wiring assembly 2113 includes a conductive member 2114 and an insulating layer 2115, wherein the insulating layer 2115 wraps the conductive member 2114, and both ends of the conductive member 2114 are provided with stoppers 2116 for positioning and electrically connecting the coil 2123. In other words, the stoppers 2116 are used to position the coil 2123 and to electrically connect the coil 2123, thereby achieving electrical connection of the coils 2123 in phase and ensuring the position stability of the coil 2123.

At the same time, by providing an insulating layer 2115 to wrap the conductive member 2114, the service life of the conductive member 2114 can be extended and the safety of the conductive member 2114 can be improved.

In some embodiments, as shown in FIGS. 78 to 86 , the stopper 2116 forms a wire clamping groove provided on the conductive member 2114. This facilitates the use of the stopper 2116 to position the coil 2123 and electrically connect the coil 2123, thereby achieving electrical connection of the coils 2123 of the same phase and reducing the difficulty of electrical connection of the coils 2123 of the same phase.

It should be noted that the main innovation of this embodiment is a winding connection method applied to the electromagnetic actuator 1000, which is novel, simple, efficient and reliable.

72 to 77, the electromagnetic actuator 1000 of this embodiment includes a mover assembly and a stator assembly, and the mover assembly and the stator assembly can move linearly relative to each other. The stator assembly includes a center rod 300, a guide bearing 840, a sealing cover 312, a first core unit 21114, a plurality of second-type cores 2112, a second core unit 21115, a wiring assembly 2113, an outlet assembly 216, and a connecting line 2121. The first core unit 21114, Multiple second-type iron cores 2112 and second iron core units 21115 are all sleeved on the outside of the center rod 300, the guide bearing 840 is assembled inside the center rod 300, and the sealing cover 312 is assembled on the top of the center rod 300, which respectively play the role of limiting and sealing.

In some embodiments, as shown in Figure 77, the connecting wire 2121 includes a first phase lead 21211, a second phase lead 21212 and a third phase lead 21213, and there are three outlets 311 on the upper part of the center pole 300. The first phase lead 21211, the second phase lead 21212 and the third phase lead 21213 pass through the three outlets 311 respectively to facilitate the connection between the connecting wire 2121 and the coil 2123.

In some embodiments, as shown in Figures 87-92, the first core unit 21114 includes a first type of core 2111, a coil 2123 and an inner lead-out device 860. The coil 2123 is sleeved on the first type of core 2111, and the coil 2123 is a multi-layer ring wound with a wire, and the radial outer joint is bent outward along the ring winding direction to form a first lead-out head 2018, and the radial inner joint is bent inward along the ring winding direction to form a second lead-out head 214, and the inner lead-out device 860 is embedded in the first type of core 2111 and connected to the second lead-out head 214 of the coil 2123, so as to facilitate the same-phase electrical connection.

In some embodiments, as shown in FIG. 89 , a first internal mounting hole 21116 for assembling the inner wire outlet device 860 is provided in the first type of iron core 2111 , so that the inner wire outlet device 860 can be embedded in the interior of the first type of iron core 2111 .

In some embodiments, the outer layer of the coil 2123 is provided with an insulating paint coating to protect the coil 2123 .

Similar to the first phase structure, the first outlet head 2018 of the upper coil 2123 of the first layer of the second type iron core 2112 is connected to the second phase lead 21212 through the fourth conductor 2164 of the short outlet assembly 2162 to form a second phase winding outlet structure, and the first outlet head 2018 of the lower coil 2123 of the first layer of the second type iron core 2112 is connected to the second phase lead 21212 through the first long conductor 2164.

Thus, the second phase structure of the stator assembly 210 is formed.

In some embodiments, in combination with FIGS. 115-118 , a first core unit 21114, a plurality of second-type cores 2112, a second core unit 21115, and a plurality of long wiring assemblies 21131 constitute a third phase structure of a stator assembly 210. In the third phase structure, a first lead 2018 of each coil 2123 is located in the same direction when viewed from top to bottom, and is staggered with the first phase structure and the second phase structure.

The conductive part 2114 of the first long wiring component 21131 is connected vertically with the first terminal 2018 of the upper coil 2123 of the second layer of the second type iron core 2112, and the first terminal 2018 of the lower coil 2123 of the second layer of the second type iron core 2112 is connected vertically with the first terminal 2018 of the upper coil 2123 of the third layer of the second type iron core 2112 through the conductive part 2114 of the second long wiring component 21131, and so on, until the first terminal 2018 of the lower coil 2123 of the last layer of the second type iron core 2112 is connected vertically with the first terminal 2018 of the coil 2123 of the bottom second iron core unit 21115 through the conductive part 2114 of the long wiring component 21131, and the third phase connector 8823 of the bottom wiring device 880 is connected to the second terminal 214 of the coil 2123, thereby forming the third phase structure of the stator assembly 210.

In summary, the outer edges of the wiring assembly 2113 and the outlet assembly 216 of this embodiment will not exceed the outer boundary of the core assembly 211, and both the wiring assembly 2113 and the outlet assembly 216 have limiting features, which can be positioned during assembly.

In some embodiments, as shown in FIGS. 119 to 122 , the wiring assembly 2113 includes a first connector 2117 and a second connector 2118, which are plugged together, and the first connector 2117 and the second connector 2118 are both provided on the core assembly 211 and electrically connected to the coil 2123. That is, the wiring assembly 2113 is not limited to the manner of forming the above-mentioned embodiment, and the wiring assembly 2113 may also include a first connector 2117 and a second connector 2118, and the first connector 2117 and the second connector 2118 are provided on the core assembly 211 and electrically connected to the coil 2123, so that when the first connector 2117 and the second connector 2118 are connected to the external component, the electrical connection between the coil 2123 and the external structural member can be realized, thereby reducing the connection difficulty of the coil 2123.

In some embodiments, one of the first connector 2117 and the second connector 2118 is a socket and the other is a plug. The socket and the plug are plugged together to facilitate the electrical connection between the coil 2123 and the external structure, thereby reducing the difficulty of connecting the coil 2123.

It should be noted that the lead-out structure of this embodiment refers to the related structure designed for the lead-out of the winding assembly 212 from the inside to the outside of the electromagnetic actuator 1000 .

Among them, the stator assembly 210 is a part of the stator assembly of the electromagnetic actuator 1000. The stator assembly is on the inner side of the entire structure, including a connecting wire 2121, a wire channel 330, a center rod 300, a first limiter 380, a winding assembly 212, an iron core assembly 211, a guide bearing 840 and a limit nut 850, wherein the winding assembly 212 and the iron core assembly 211 constitute the stator assembly 210 (the specific structure of the electromagnetic actuator 1000 can be seen in Figure 22).

In some embodiments, in combination with Figures 119, 120 and 121, the winding assembly 212 and the core assembly 211 are both annular, and the winding assembly 212 is installed on both the upper and lower surfaces of the core assembly 211. The stator assembly 210 is formed by stacking a plurality of winding assemblies 212 and core assemblies 211 one layer at a time (as shown in Figure 122). After stacking, they are put on the center rod 300 to finally become a cylindrical shape.

In some embodiments, three grooves 20111 are evenly distributed on the circumference of the core assembly 211, and the three grooves 20111 respectively correspond to the three-phase lines of the motor. Three second connectors 2118 are provided on the core assembly 211, and the winding of the winding assembly 212 passes through one of the second connectors 2118 and forms a first connector 2117 to realize the first connector 2117 on the core assembly 211, while the other two second connectors 2118 are through-connected, and the other side correspondingly also has a second connector 2118 outlet, and the other two outlets are through-connected. The first connectors 2117 on both sides of the core assembly 211 are respectively formed as raised and recessed female and male end fittings.

In some embodiments, the winding assembly 212 and the core assembly 211 are stacked in sequence according to the three phases A, B, and C, that is, the winding assemblies 212 of the same phase are not adjacent. Therefore, as shown in Figure 122, the first joint 2117 on one side of the core assembly 211 needs to pass through multiple core assemblies 211 assembled with winding assemblies 212 of other phases to be connected to the core assembly 211 assembled with the winding assemblies 212 of the same phase, so the first joint 2117 is longer.

It should be noted that in this embodiment, the connection of the same-phase winding assembly 212 is achieved through the first joint 2117, so that the connection of the same-phase winding does not require welding and is firm and reliable. The first joint 2117 passes through the inner side of the core assembly 211 without affecting the mutual movement of the stator assembly 210 and the movable assembly 220, thereby avoiding damage to the winding due to movement between the stator assembly 210 and the movable assembly 220, thereby ensuring the performance of the coil 2123.

In some embodiments, the connecting line 2121 respectively enters from the top and exits from the bottom of the wire passing channel 330. Three pipe outlets are provided at the bottom of the wire passing channel 330. There are three wire outlets 311 on the center pole 300. The three pipe outlets of the wire passing channel 330, the three wire outlets of the center pole 300 and the three second joints 2118 on the core assembly 211 correspond one to one. During assembly, the wire passing channel 330 is provided on the center pole 300, and the connecting line 2121 respectively passes through the wire passing channel 330 and the wire outlet 311 of the center pole 300.

Through the above-mentioned arrangement, the wire output can be fixed in the whole process, wherein the center rod 300 plays the role of fixing and protecting the wiring, which well solves the problem of the risk of extrusion and scratching in the prior art. In addition, a first limiting member 380 is sleeved on the top of the center rod 300, and the first limiting member 380 and the outlet of the center rod 300 jointly fix the connecting line 2121. At the same time, the first limiting member 380 is made of rubber material, which can buffer the impact of surrounding components on the connecting line 2121 under extreme working conditions, thereby protecting the connecting line 2121 and ensuring the reliability of the electrical system.

In summary, the wire output structure of the electromagnetic actuator 1000 of this embodiment utilizes the relative relationship of the surrounding components and is cleverly designed to solve the problem of wire output difficulties. It has the advantages of safety and reliability, easy disassembly and assembly, and compact space design.

In some embodiments, as shown in FIGS. 132 to 136 , the electromagnetic actuator 1000 further includes a first stopper 380 and a second stopper 390, which are arranged on the center rod 300 at intervals along the axial direction of the center rod 300, and the first stopper 380 and the second stopper 390 are respectively abutted against the core assembly 211 to limit the axial displacement of the core assembly 211. This prevents the core assembly 211 from moving relative to the center rod 300 along the axial direction of the center rod 300, so that the core assembly 211 can be more firmly arranged on the center rod 300, and the magnetic core 211 can be prevented from falling off the center rod 300. This ensures that the core assembly 211 is installed stably and reliably on the center rod 300 .

In some embodiments, as shown in FIGS. 132-136 , the first stopper 380 and the second stopper 390 are respectively adapted to abut against the inner wall of the housing 100 to limit the range of movement of the housing 100. Here, it means that during the movement of the housing 100, the first stopper 380 and the second stopper 390 can abut against the inner wall of the housing 100 respectively, thereby limiting the range of movement of the housing 100, ensuring the position stability of the movement of the housing 100, and thus ensuring the working performance of the electromagnetic actuator 1000.

In some embodiments, as shown in Figures 132-136, one of the first stopper 380 and the second stopper 390 is an integral part with the center rod 300 and the other is a separate part from the center rod 300. The integral part can reduce the number of parts of the electromagnetic actuator 1000 and reduce the complexity of the structure of the electromagnetic actuator 1000.

In some embodiments, as shown in Figures 132 and 133, the first limit member 380 and the center rod 300 are integrally formed. Since the relative position of the first limit member 380 and the center rod 300 is unchanged, when the core assembly 211 is sleeved on the center rod 300, it is convenient to achieve the coordination between the first limit member 380 and the core assembly 211, so as to use the first limit member 380 to limit the position of the core assembly 211 along the axial direction of the center rod 300.

In some embodiments, in combination with Figures 132 and 133, the center rod 300 is provided with a protrusion protruding radially outward to define the first limit member 380, so that the first limit member 380 and the center rod 300 are an integrally formed part, and the connection between the first limit member 380 and the center rod 300 is omitted.

In some embodiments, the other of the first stopper 380 and the second stopper 390 is threadedly engaged with the center rod 300. Here, it means that when one of the first stopper 380 and the second stopper 390 is an integral part with the center rod 300, the other of the first stopper 380 and the second stopper 390 is threadedly engaged with the center rod 300 to achieve a fixed connection between the other of the first stopper 380 and the second stopper 390 and the center rod 300, ensuring the position stability of the other of the first stopper 380 and the second stopper 390, so as to facilitate the first stopper 380 and the second stopper 390 to cooperate with each other to limit the axial displacement of the core assembly 211.

In some embodiments, the second limiting member 390 is formed as a threaded member, and the threaded member is threadedly matched with the central rod 3000 so that the second limiting member 390 can be detachably disposed on the central rod 300 .

In some embodiments, in combination with Figures 132 and 134, the other of the first limit member 380 and the second limit member 390 includes a first part 391 and a second part 392, the first part 391 cooperates with the center rod 300, and in the radial direction of the center rod 300, the second part 392 is located radially outside the first part 391; in the axial direction of the center rod 300, the axial length of the first part 391 is greater than the axial length of the second part 392, a part of the second part 392 stops at the core assembly 211 and the other part is spaced apart from the core assembly 211. Among them, by setting the axial length of the first part 391 to be greater than the axial length of the second part 392, the area of the first part 391 cooperating with the center rod 300 is increased, thereby facilitating the other of the first limit member 380 and the second limit member 390 to be firmly set on the center rod 300. Since the core assembly 211 contains a wire outlet groove and a wiring harness, by setting the axial length of the first part 391 to be greater than the axial length of the second part 392, the axial length of the second part 392 can also be made smaller, which is convenient for avoiding the wiring harness.

At the same time, by positioning the second portion 392 radially outward of the first portion 391, a portion of the second portion 392 can be stopped against the core assembly 211, thereby utilizing the other of the first limiting member 380 and the second limiting member 390 to limit the axial displacement of the core assembly 211.

In addition, by spacing another part of the second portion 392 from the core assembly 211, heat dissipation of the core assembly 211 is facilitated, and a gap exists between another part of the second portion 392 and the core assembly 211, thereby avoiding stress concentration.

It should be explained here that, with respect to the inner and outer sides being the axis of the center rod 300 , the first part 391 is closer to the center rod 300 , and the second part 392 is farther from the center rod 300 . Therefore, in the radial direction of the center rod 300 , the second part 392 is located radially outside the first part 391 .

In some embodiments, in combination with Figures 135 and 136, the other of the first limit member 380 and the second limit member 390 is installed to the end of the center rod 300 and a portion of it extends into the center rod 300, so that the other of the first limit member 380 and the second limit member 390 can be removably set in the center rod 300, so that after the core assembly 211 is axially sleeved on the center rod 300, at least one of the first limit member 380 and the second limit member 390 is installed on the center rod 300, so as to limit the axial displacement of the core assembly 211 along the center rod 300 after the core assembly 211 is installed in place.

In some embodiments, the second portion 392 of the other of the first stopper 380 and the second stopper 390 is formed as a mounting structure with a buffer member. In this way, while the other of the first stopper 380 and the second stopper 390 is fixedly mounted on the center rod 300, the other of the first stopper 380 and the second stopper 390 can also play a buffering role.

In some embodiments, the first limiting member 380 and the second limiting member 390 are made of rubber material so that the first limiting member 380 and the second limiting member 390 can play a buffering role.

In some embodiments, as shown in Figures 135 and 136, the second limit member 390 is installed to the end of the center rod 300 and a portion of it extends into the center rod 300. The second limit member 390 includes a piston portion 393. The piston portion 393 is made of an elastic material. When the piston portion 393 is extended into the center rod 300, the piston portion 393 is elastically deformed and compressed to have an interference fit with the center rod 300 to fix the piston portion 393 on the center rod 300.

Part of the structure of the second limiter 390 protrudes from the piston portion 393 in the radial direction of the center rod 300 , and part of the structure of the second limiter 390 cooperates with the core assembly 211 to limit the displacement of the core assembly 211 along the axial direction of the center rod 300 .

In some embodiments, the first stopper 380 and the second stopper 390 are also formed as stopper components of the stator assembly 210 to limit the relative displacement of the stator assembly 210 .

In some embodiments, during the operation of the electromagnetic actuator 1000, the core assembly 211 and the housing 100 will undergo relative linear motion, and the first limit member 380 can simultaneously serve as a lower limit for limiting the movement of the housing 100, and the second limit member 390 can simultaneously serve as an upper limit for limiting the movement of the housing 100.

In some embodiments, the first limiter 380 serves to limit the press-fitting depth of the core assembly 211. After the press-fitting is completed, the second limiter 390 is connected to the bottom of the center rod 300 to prevent the core assembly 211 from falling off axially downward.

It should be noted that specific implementation forms of the first limit member 380 and the second limit member 390 include but are not limited to a nut, a piston, an integrated step surface, and the like.

In some embodiments, as shown in FIG. 128 , FIG. 129 and FIG. 130 , at least one cooling chamber 320 for accommodating a cooling medium is provided in the center rod 300. The center rod 300 can be filled with a cooling medium, so that the cooling medium can be used to dissipate heat from the core assembly 211, thereby ensuring that the electromagnetic actuator 1000 can operate efficiently for a long time and avoid damaging the components of the internal electromagnetic actuator 1000.

In some embodiments, the inner wall of the center rod 300 is hollow to form a cooling chamber 320, and a cooling medium is added from a filling port 323 before assembly (the filling port 323 is The specific structure can be seen in Figure 25), and then the filling port 323 is sealed to make the cooling chamber 320 a sealed cavity. When the electromagnetic actuator 1000 is running, the heat on the core assembly 211 is transferred to the cooling medium through the center rod 300, and the cooling medium transfers the heat to the air through a heat exchange cycle, thereby ensuring the long-term and efficient operation of the electromagnetic actuator 1000 and avoiding damage to internal components.

At the same time, this design does not require any additional components such as cooling pipes, and the entire cooling solution has a compact structure.

In some embodiments, the radial projection of at least a portion of the cooling chamber 320 is arranged to overlap with the core assembly 211. Thus, at least a portion of the cooling chamber 320 can face the core assembly 211 in the radial direction, so that the cooling medium in the cooling chamber 320 can be used to dissipate heat from the core assembly 211, thereby ensuring that the electromagnetic actuator 1000 can operate efficiently for a long time and avoid damaging the internal parts of the electromagnetic actuator 1000.

In some embodiments, at least part of the cooling chamber 320 is located outside the accommodating chamber 130. This facilitates the delivery of the cooling medium to the cooling chamber 320 and helps cool the cooling medium to ensure the heat dissipation performance of the cooling medium.

In some embodiments, the electromagnetic actuator 1000 further includes a first cooling pipe, which is disposed in the cooling chamber 320, and a first cooling cavity is formed between the first cooling pipe and the cooling chamber 320, and one of the first cooling cavity and the first cooling pipe is adapted to be connected to the first water inlet, and the other is adapted to be connected to the first water outlet (not shown in the example figure). In this way, the cooling medium can circulate between the first cooling cavity and the first cooling pipe, thereby facilitating the use of the cooling medium to dissipate heat from the core assembly 211 and ensuring the heat dissipation performance of the cooling medium.

In some embodiments, the first cooling tube is spaced apart from the inner wall of the cooling chamber 320 so that a connecting channel is formed between the first cooling tube and the cooling chamber 320, and the connecting channel is used to connect the first cooling chamber and the first cooling tube. In this way, when one of the first cooling chamber and the first cooling tube is connected to the first water inlet and the other is connected to the first water outlet, it can be ensured that the cooling medium between the first water inlet and the first water outlet can flow through the first cooling chamber and the first cooling tube in sequence, which is conducive to the circulation of the cooling medium, thereby facilitating the use of the cooling medium to dissipate heat from the core assembly 211.

In some embodiments, as shown in FIGS. 137-140 , the electromagnetic actuator 1000 further includes a second cooling pipe 32111 and a third cooling pipe 32121, both of which are disposed in the cooling chamber 320 and communicate with the cooling chamber 320, and one of the second cooling pipe 32111 and the third cooling pipe 32121 is adapted to communicate with the second water inlet 3211, and the other is adapted to communicate with the second water outlet 3212. In this way, the cooling medium can enter the cooling chamber 320 through the second water inlet 3211 and be discharged from the cooling chamber 320 through the second water outlet 3212, which is conducive to realizing the circulation of the cooling medium.

In some embodiments, in combination with Figures 138 and 139, the second cooling pipe 32111 is connected to the second water inlet 3211, and the third cooling pipe 32121 is connected to the second water outlet 3212, so that the cooling medium can enter the cooling chamber 320 through the second cooling pipe 32111 and be discharged from the cooling chamber 320 through the third cooling pipe 32121, which is conducive to the circulation of the cooling medium.

In some embodiments, as shown in FIG. 139 and FIG. 140, the cooling chamber 320 is multiple and includes a first cooling chamber 321 and a second cooling chamber 322. In the axial direction of the center rod 300, the first cooling chamber 321 is located on one side of the core assembly 211, and at least a portion of the second cooling chamber 322 is arranged directly opposite to the core assembly 211. Thus, at least a portion of the radial projection of the cooling chamber 320 is arranged to overlap with the core assembly 211, so that the cooling medium in the cooling chamber 320 can be used to dissipate heat from the core assembly 211, thereby ensuring that the electromagnetic actuator 1000 can operate efficiently for a long time and avoid damaging the internal components of the electromagnetic actuator 1000.

Through the unfamiliar setting, the first cooling chamber 321 and the second cooling chamber 322 can be used to dissipate heat from different parts of the electromagnetic actuator 1000 respectively, and interact with each other to ultimately ensure that the electromagnetic actuator 1000 maintains efficient operation. The center rod 300 plays a role in rapid heat conduction and heat dissipation during the entire cooling process.

In some embodiments, the second cooling chamber 322 is formed as a closed chamber and is filled with a cooling medium.

In some embodiments, as shown in FIG. 139 and FIG. 140 , there are multiple second cooling chambers 322 that are spaced apart along the circumference of the central rod 300 , and each second cooling chamber 322 includes multiple sub-chambers 3221 spaced apart along the circumference of the central rod 300 , so as to ensure the heat dissipation performance of the cooling chamber 320 .

In some embodiments, in the axial direction of the central rod 300, the ends of the multiple sub-chambers 3221 of each second cooling chamber 322 are connected, so that the cooling medium in each second cooling chamber 322 can circulate between the multiple sub-chambers 3221, thereby ensuring the heat dissipation performance of the second cooling chamber 322.

In some embodiments, at least a portion of the structure of the cooling chamber 320 is formed as a heat pipe, so that the cooling chamber 320 itself has the ability to dissipate heat, thereby reducing the temperature of the cooling medium and ensuring the cooling effect of the cooling medium.

In some embodiments, a cooling structure 810 is provided on the central rod 300 (the specific structure of the cooling structure 810 can be seen in FIG. 22 ), and the cooling structure 810 is provided on the portion of the central rod 300 extending out of the accommodating cavity 130. The cooling structure 810 is used to reduce the temperature of the cooling medium and ensure the cooling effect of the cooling medium.

In some embodiments, the cooling structure 810 includes a heat sink, which improves the heat dissipation performance of the cooling structure 810, thereby utilizing the cooling structure 810 to reduce the temperature of the cooling medium and ensure the cooling effect of the cooling medium.

In some embodiments, the cooling structure 810 includes a cooling pipeline, and a third water inlet and a third water outlet are formed on the cooling pipeline, which are connected to the outside. The third water inlet and the third water outlet are used to transport the cooling medium with a lower external temperature into the cooling structure 810, thereby reducing the temperature of the cooling medium in the cooling structure 810, which can also ensure the heat dissipation performance of the cooling structure 810, so that the cooling structure 810 can effectively reduce the temperature of the cooling medium and ensure the cooling effect of the cooling medium.

In some embodiments, as shown in FIG. 137 , a guide rod 400 is provided on the housing 100, and a guide hole 310 is formed on the center rod 300, and the guide rod 400 cooperates with the guide hole 310. This is to prevent the housing 100 from deflecting during movement, that is, to ensure that the housing 100 can move in a predetermined direction, and to ensure the accuracy of the movement of the housing 100.

In some embodiments, a cooling cavity is provided on the guide rod 400, and the cooling cavity is suitable for containing a coolant, so that the coolant can be used to further dissipate heat from the core assembly 211, thereby ensuring that the electromagnetic actuator 1000 can operate efficiently for a long time and avoid damaging the internal parts of the electromagnetic actuator 1000.

In some embodiments, the volume of the cooling cavity is greater than the volume of the cooling liquid. That is, the cooling liquid does not fill the entire cooling cavity, so that the cooling liquid in the cooling cavity can undergo a gas-liquid conversion process to ensure the cooling performance of the cooling liquid.

In some embodiments, the radial projection of the cooling cavity is at least partially overlapped with the core assembly 211. Thus, the cooling cavity can face the core assembly 211 in the radial direction, so that the cooling liquid in the cooling cavity can be used to dissipate heat from the core assembly 211, further ensuring that the electromagnetic actuator 1000 can operate efficiently for a long time and avoid damaging the internal parts of the electromagnetic actuator 1000.

In some embodiments, the radial projection of the core assembly 211 that overlaps with the cooling cavity partially overlaps with the radial projection of the cooling chamber 320. In other words, part of the core assembly 211 faces both the cooling cavity on the guide rod 400 and the cooling chamber 320 on the center rod 300, maximizing the heat dissipation performance of the core assembly 211.

In some embodiments, as shown in FIG22 , the electromagnetic actuator 1000 further includes a detection module 900, which is used to detect the relative displacement between the housing 100 and the stator assembly 210. In this way, the position of the stator assembly 210 can be accurately determined, the movement of the stator assembly 210 can be controlled, and the position accuracy of the stator assembly 210 after movement can be ensured, thereby improving the working performance of the electromagnetic actuator 1000.

At the same time, using the detection module 900 to detect the relative displacement between the housing 100 and the stator assembly 210 can also reduce the difficulty of detecting the position of the stator assembly 210 and ensure the accuracy of the position detection of the stator assembly 210 .

That is to say, the electromagnetic actuator 1000 of this embodiment ensures the control accuracy of the moving position of the stator assembly 210 by providing the detection module 900, thereby avoiding the technical problem of control accuracy defects.

In some embodiments, the detection module 900 can sense signals corresponding to different positions of the device under test and output position signals to the controller through wires, so as to detect the relative displacement of the housing 100 and the stator assembly 210 .

In some embodiments, as shown in FIGS. 141 to 146 , the detection module 900 includes a laser sensor 910, which is disposed at the top or bottom of the accommodating cavity 130. This facilitates the use of the laser sensor 910 to detect the relative displacement of the housing 100 and the stator assembly 210, thereby ensuring the accuracy of the relative displacement detection of the housing 100 and the stator assembly 210 and reducing the difficulty of detecting the relative displacement of the housing 100 and the stator assembly 210.

In some embodiments, as shown in FIG. 141 and FIG. 142 , the housing 100 is suitable for being fixed to the axle, the electromagnetic actuator 1000 further comprises a mounting bracket 192, the mounting bracket 192 is mounted to the outside of the housing 100 and is suitable for connecting the axle and the housing 100, the laser sensor 910 is arranged in the mounting bracket 192, and the bottom wall of the accommodating cavity 130 is provided with an avoidance hole 131 for avoiding the optical path of the laser sensor 910. Among them, by arranging the laser sensor 910 on the mounting bracket 192, the laser sensor 910 is arranged on the housing 100, so that the housing 100 is conveniently used to support the laser sensor 910, and the position stability of the laser sensor 910 is improved, and because the bottom wall of the accommodating cavity 130 is provided with the avoidance hole 131 for avoiding the optical path of the laser sensor 910, the optical path generated by the laser sensor 910 arranged on the mounting bracket 192 can be projected to the accommodating cavity 130, so that the laser sensor 910 can be used to detect the relative displacement of the housing 100 and the stator assembly 210.

In some embodiments, as shown in FIG. 143 , a first sensor mounting bracket 920 is provided at one end of the mounting bracket 192, and the laser sensor 910 is disposed on the first sensor mounting bracket 920, so that the laser sensor 910 can be disposed on the mounting bracket 192, which facilitates the use of the housing 100 to support the laser sensor 910, improves the position stability of the laser sensor 910, and reduces the difficulty of fixing the laser sensor 910.

The laser sensor 910 and the first sensor mounting bracket 920 may be fixed by bolt connection.

In some embodiments, as shown in FIGS. 142-146 , in the axial direction of the electromagnetic actuator 1000 , the laser sensor 910 is directly opposite to the stator assembly 210 , so that the light path generated by the laser sensor 910 can be projected onto the stator assembly 210 , thereby facilitating the use of the laser sensor 910 to detect the relative displacement between the housing 100 and the stator assembly 210 .

In some examples, the laser sensor 910 mainly determines the position by sensing the reflected light from the object and outputs the displacement signal of the electromagnetic actuator 1000. The working principle is that before the electromagnetic actuator 1000 is started, the height of the laser sensor 910 is first calibrated and the position of the laser sensor 910 is measured. When the housing 100 moves upward relative to the center rod 300 (as shown in FIG. 144 ), the laser sensor 910 projects a visible light spot on the surface of the stator assembly 210. The light reflected from the light spot is imaged on the photosensitive element in the laser sensor 910 through the light receiving system. When the laser sensor 910 and the stator assembly 210 are in contact, the laser sensor 910 and the stator assembly 210 are in contact. 0 changes, the laser reflection angle will also change accordingly, causing the imaging position on the photosensitive element in the laser sensor 910 to change, thereby measuring the current position of the laser sensor 910 and the stator assembly 210. When the housing 100 moves downward relative to the center rod 300 (as shown in FIG. 145 ), the laser sensor 910 measures the current position of the laser sensor 910 and the stator assembly 210 again according to the above method. The relative displacement of the housing 100 and the stator assembly 210 can be obtained by analyzing the changes in the position values before and after the two times, thereby achieving the purpose of detecting the relative displacement of the housing 100 and the stator assembly 210.

Through the above settings, the present embodiment can be formed into an active measurement with a high measurement frequency, and the height parameters of the electromagnetic actuator 1000 can be obtained in real time. Whether it is low-frequency vibration or even the stationary state of the vehicle 20000, it will not affect the measurement parameters, that is, when the vehicle 20000 is stationary, it can still provide information such as the vehicle posture. Therefore, the laser sensor 910 of the present embodiment can not only be used to measure the stroke of the electromagnetic actuator 1000, but also can obtain the movement speed of the electromagnetic actuator 1000 through the functional relationship between the difference in the stroke of the electromagnetic actuator 1000 and time. Taking Figures 144 and 145 as examples, within a reflection receiving cycle time of the laser sensor 910, the position of the housing 100 changes from Figure 144 to Figure 145, so that the average speed of the electromagnetic actuator 1000 within a laser reflection receiving cycle can be calculated. Because the measurement frequency of the laser sensor 910 is high, this speed can reflect the real-time speed of the movement of the electromagnetic actuator 1000 to a certain extent.

In some examples, the loads on different axles of vehicle 20000 can be preliminarily calculated by comparing the initial state of vehicle 20000. The basic principle is to measure the height of the four wheels of vehicle 20000 when vehicle 20000 starts or when vehicle 20000 is about to move. Since vehicle 20000 has no relative motion and road impact at this time, the distance change can be regarded as the load compression damping. Based on this, the empty or fully loaded state of vehicle 20000 can be judged, thereby providing a more accurate reference basis for four-wheel control.

Similarly, the changes in different speeds of the electromagnetic actuator 1000 within a laser reflection and reception cycle can reflect the real-time acceleration of the electromagnetic actuator 1000 to a certain extent. In theory, the number of sensors installed on the vehicle 20000 can be greatly reduced, achieving the purpose of economical design.

It should also be noted that, in this embodiment, the laser sensor 910 is arranged at the bottom of the electromagnetic actuator 1000, and the detection position is the bottom plane of the stator assembly. Since the main movement of the housing 100 and the stator assembly 210 is a linear movement up and down, but in an actual motion scenario, the housing 100 and the stator assembly 210 will also rotate relative to each other around the center rod 300. Through the above arrangement, even if the housing 100 and the stator assembly 210 are deflected, it can be ensured that the top of the mounting bracket 192, the laser sensor 910 and the bottom surface of the stator assembly 210 remain parallel (as shown in FIG. 146), thereby preventing the position data detected by the laser sensor 910 from being affected by the deflection of the housing 100 and the stator assembly 210.

At the same time, since the laser sensor 910 is installed on the mounting bracket 192, the high temperature generated during the movement of the electromagnetic actuator 1000 can be avoided from interfering with the laser sensor 910, thereby ensuring the working performance of the laser sensor 910. At the same time, the laser sensor 910 is installed on the outside of the electromagnetic actuator 1000, which makes it easier to replace and install the laser sensor 910 and more conducive to after-sales replacement and maintenance.

In summary, this embodiment makes full use of the mounting bracket 192 and uses the laser sensor 910 with higher measurement accuracy to make up for the various shortcomings of traditional sensors, and comprehensively surpasses traditional designs in many aspects such as layout space, measurement accuracy, measurement content, service life, and maintenance convenience.

In some embodiments, as shown in FIGS. 150-163, the detection module 900 includes a first detection member 930 and a second detection member 940, the second detection member 940 is coupled to the first detection member 930, and one of the housing 100 and the center rod 300 is provided with the first detection member 930 and the other is provided with the second detection member 940. Thus, the second detection member 940 and the first detection member 930 are used to detect the relative displacement of the housing 100 and the stator assembly 210, so as to ensure the accuracy of the position detection of the stator assembly 210 and reduce the difficulty of the position detection of the stator assembly 210.

In some embodiments, as shown in FIGS. 150-163 , the housing 100 is suitable for being fixed to the axle, and the center rod 300 passes through the top wall of the housing 100 to be connected to the vehicle body; the first detection member 930 is provided on the housing 100, and the second detection member 940 is provided on the center rod 300. The housing 100 is used to support the first detection member 930, and the center rod 300 is used to support the second detection member 940, thereby improving the position stability of the first detection member 930 and the second detection member 940, and facilitating the second detection member 940 to cooperate with the first detection member 930 to detect the relative displacement of the housing 100 and the stator assembly 210.

In some embodiments, as shown in Figures 147-150, the center rod 300 is provided with an assembly groove 950 (the specific structure of the assembly groove 950 can be seen in Figure 25), the second detection member 940 is fixed on the assembly groove 950 of the center rod 300, and the housing 100 is provided with a first detection member installation groove 960 facing the assembly groove 950, and the first detection member 930 is arranged in the first detection member installation groove 960, forming a complete working environment for the first detection member, thereby facilitating the use of the second detection member 940 and the first detection member 930 to detect the relative displacement of the housing 100 and the stator assembly 210.

In some embodiments, as shown in FIG. 148 , the bearing 170 covers the top of the first detection member 930 , protecting the travel of the first detection member 930 and preventing the first detection member 930 from being squeezed when the housing 100 moves upward, thereby ensuring the performance of the first detection member 930 .

In some embodiments, as shown in FIG. 150 , the center rod 300 is provided with a first anti-rotation portion 370, and the housing 100 is provided with an anti-rotation hole 193. The anti-rotation column passes through the anti-rotation hole 193 and extends into the first anti-rotation portion 370 to limit the rotational freedom of the center rod 300 and prevent the center rod 300 and the housing 100 from rotating relative to each other, so that the second detection member 940 located on the center rod 300 can be precisely aligned with the first detection member 930 located on the housing 100, thereby ensuring the detection performance of the detection module 900.

In some embodiments, as shown in FIGS. 151 to 154 , the first detection member 930 is disposed outside the housing 100 , so as to reduce the difficulty of installing the first detection member 930 , and at the same time, it is also convenient to replace and repair the first detection member 930 , thereby reducing the difficulty of maintaining the first detection member 930 .

At the same time, by arranging the first detection component 930 on the outside of the casing 100, the high temperature area of the casing 100 can be effectively avoided, and the first detection component 930 can use natural wind to dissipate heat, which fully protects the first detection component 930 and avoids failure of the first detection component 930 to a certain extent.

In some embodiments, as shown in FIG. 152 , a bearing 170 is disposed between the center rod 300 and the housing 100, and the portion where the radial projection of the first detection member 930 overlaps with the housing 100 partially overlaps with the radial projection of the bearing 170. That is, in the radial direction of the housing 100, the first detection member 930 partially overlaps with the bearing 170, so that under the premise that the extension length of the center rod 300 is certain, it is possible to avoid excessively reducing the extension length of the bearing 170 due to the provision of the first detection member 930, that is, by partially overlapping the first detection member 930 with the bearing 170, the extension length of the bearing 170 can be guaranteed, thereby ensuring the guiding effect of the bearing 170.

In some embodiments, the bearing 170 is provided with a sensor avoidance groove, and the first detection member 930 is provided in the sensor avoidance groove, so that the portion where the radial projection of the first detection member 930 overlaps with the housing 100 partially overlaps with the radial projection of the bearing 170. At the same time, the difficulty of fixing the first detection member 930 can be reduced, and the position stability of the first detection member 930 can be improved, thereby ensuring the working performance of the first detection member 930 to a certain extent.

In some embodiments, a bearing 170 is disposed between the center rod 300 and the housing 100, and the first detection member 930 is spaced apart from the bearing 170. That is to say, it is not limited to partially overlapping the radial projection of the first detection member 930 with the housing 100, and the radial projection of the bearing 170, and the first detection member 930 and the bearing 170 can also be spaced apart, so that the first detection member 930 and the bearing 170 are independent of each other, and the working performance of the first detection member 930 and the bearing 170 is guaranteed.

The interval arrangement mentioned here can be understood as the first detection member 930 and the bearing 170 being arranged at intervals in the axial direction of the center rod 300 so that the first detection member 930 and the bearing 170 are independent of each other.

At the same time, a bearing 170 is provided between the center rod 300 and the housing 100 to limit the movement of the center rod 300. In this way, the center rod 300 moves along the bearing 170, and the center rod 300 is prevented from easily deviating as shown in FIG. 158 during the movement of the vehicle 20000. The greater the deflection angle of the center rod 300, the greater the impact on the detection accuracy of the first detection member 930 and the second detection member 940, and even failure.

Thus, by setting the bearing 170, the first detection member 930 and the second detection member 940 have good alignment during movement and high detection accuracy, thereby ensuring that during normal operation of the detection module 900, the working surface of the first detection member 930 needs to remain parallel to the working surface of the second detection member 940 (as shown in Figure 157), so as to ensure that the second detection member 940 can obtain accurate magnetic field signals, thereby ensuring the working performance of the detection module 900.

In some embodiments, the first detection member 930 forms a magnetic field sensing element, and the second detection member 940 forms a magnetic field output element. As shown in FIG. 155 , the second detection member 940 can obtain displacement within a certain range of travel by sensing the magnetic field of the second detection member 940, and the magnetic field signals at any two different positions within the travel are different, such as a linear relationship; as shown in FIG. 156 , the first detection member 930 can sense the magnetic field signal emitted by the second detection member 940, and then convert it into an electrical signal, and the electrical signals at any two different positions within the travel are different, such as a linear relationship. There are many means of conversion here, such as the Hall principle. Finally, the sensed electrical signal (or converted into other signals, such as digital signals) is transmitted as an output signal to achieve the purpose of using the second detection member 940 and the first detection member 930 to cooperate in detecting the relative displacement of the housing 100 and the stator assembly 210.

In summary, the first detection component 930 mainly detects the relative displacement of the housing 100 and the stator assembly 210 by identifying the magnetic field signal of the second detection component 940. However, the magnetic field intensity emitted by the mover assembly 220 and the stator assembly 210 in the electromagnetic actuator 1000 is very high, which can easily interfere with the detection accuracy of the first detection component 930, resulting in a decrease in the accuracy of the detection module 900 or even failure.

In order to solve the above problem, the center rod 300 and the housing 100 can be supported by non-magnetic materials, as shown in Figure 153. The magnetic field generated by the movable assembly 220 and the stator assembly 210 inside the electromagnetic actuator 1000 is distributed along the center rod 300 and the housing 100, and forms a closed magnetic field loop, so that the magnetic field strength at the position of the second detection member 940 is significantly increased, thereby avoiding the magnetic field generated by the movable assembly 220 and the stator assembly 210 inside the electromagnetic actuator 1000 from forming a divergent shape as shown in Figure 154.

At the same time, the distance between the detection module 900 and the mover assembly 220 and the stator assembly 210 can be increased to improve the magnetic field strength at the position of the second detection member 940, so that the magnetic field strength at the position of the second detection member 940 is significantly increased, thereby ensuring the detection accuracy of the detection module 900.

In some embodiments, as shown in FIGS. 159 to 164, a mounting bracket 192 is provided at the bottom of the housing 100, and a bypass channel 1921 communicating with the accommodating chamber 130 is provided in the mounting bracket 192; at least a portion of the second detection member 940 is located in the bypass channel 1921, and the first detection member 930 can be moved into the bypass channel 1921 to couple with the second detection member 940. This facilitates the use of the second detection member 940 and the first detection member 930 to cooperate in detecting the relative displacement of the housing 100 and the stator assembly 210, thereby ensuring the accuracy of the position detection of the stator assembly 210 and reducing the difficulty of the position detection of the stator assembly 210.

At the same time, by locating at least a portion of the second detection member 940 in the avoidance channel 1921 , it is convenient to reduce the space reserved by the electromagnetic actuator 1000 for the detection module 900 , which is beneficial to the miniaturized design of the electromagnetic actuator 1000 .

In some embodiments, as shown in FIG. 159 , FIG. 160 and FIG. 161 , the first detection member 930 includes a first detection member connecting end 931 , a connecting rod 932 The first detecting member 930 is fixed to the center rod 300 via the first detecting member connecting end 931, which may be a bolted connection. The wiring harness of the first detecting member 930 is arranged inside the connecting rod 932 and connected to the sensing head 933. The sensing head 933 can sense the magnetic field strength at different areas on the second detecting member 940. By analyzing the different magnetic field strengths sensed by the sensing head 933, the relative displacement of the housing 100 and the stator assembly 210 can be determined.

In some embodiments, at least a portion of the second detection member 940 is attached to the avoidance channel 1921. Adhesives may be used for attachment and fixation.

In some embodiments, the second detection component 940 is a magnetic scale, which is a device with its own magnetic field. The first detection component 930 is a Hall sensor, which outputs a displacement signal by sensing the changes in the magnetic field on the surface of the magnetic scale, thereby achieving the purpose of detecting the relative displacement of the housing 100 and the stator assembly 210.

In some embodiments, because both the movable assembly 220 and the stator assembly 210 generate magnetic fields, and when the housing 100 moves upward, as shown in Figures 162 and 163, the second detection component 940 is closer to the movable assembly 220 and the stator assembly 210. Therefore, the housing 100, the center rod 300, the connecting rod 932 and the mounting bracket 192 are all supported by non-magnetic materials, such as aluminum alloy materials. The use of the above materials can effectively shield the magnetic field generated by the movable assembly 220 and the stator assembly 210 around the first detection component 930 and the second detection component 940, thereby ensuring the detection accuracy of the detection module 900.

In some embodiments, the coercive force of the second detection member 940 is higher than the coercive force of the movable subassembly 220 to ensure that the second detection member 940 is not magnetized by the movable subassembly 220 , thereby ensuring the performance of the second detection member 940 .

In some embodiments, as shown in FIGS. 164 to 167 , the second detection member 940 is formed into an arc shape to avoid induction failure between the second detection member 940 and the first detection member 930 when the mover assembly 220 and the stator assembly 210 rotate relative to each other, thereby facilitating the first detection member 930 to stably sense the magnetic field strength at different positions on the second detection member 940 and ensure the detection accuracy of the detection module 900 .

The radius of the arc can be adaptively adjusted according to the radius of the housing 100 , and the angle of the arc can be determined according to the limit angle of relative rotation between the mover assembly 220 and the stator assembly 210 .
