Description
Technical Field
The invention relates to the technical field of compressors, in particular to a foot pad assembly, a compressor and refrigeration equipment.
Background
The compressor is generally mounted on the bottom plate of the refrigerator system through a foot pad at the bottom, so that vibration generated by the compressor during operation is transmitted to the bottom plate of the refrigerator system through the foot pad. At present, a compressor foot pad is usually rubber, and during the working operation process of a compressor, the rubber pad absorbs and releases vibration energy of the compressor, and the rubber pad has high flexibility and hardness, and if the rubber pad has low hardness, the rubber pad has high capacity of inhibiting vibration of a refrigerator system. However, since the mass of the compressor is completely supported by the rubber pad, the excessively soft rubber pad may be deformed or even crushed during the long-term operation of the refrigerator, thereby resulting in a reduction in vibration damping effect of the rubber pad.
Therefore, how to design a foot pad assembly capable of improving the shock absorbing effect is a problem to be solved.
Disclosure of Invention
The invention aims to at least solve the problem of poor damping effect on the compressor.
To this end, a first aspect of the present invention provides a foot pad assembly.
A second aspect of the present invention provides a compressor.
A third aspect of the present invention provides a refrigeration appliance.
In view of the above, a first aspect of the present invention provides a foot pad assembly, which includes a first elastic member having a first accommodating cavity, a second elastic member disposed in the first accommodating cavity and adhered to an inner wall of the first accommodating cavity, and a supporting portion disposed on the first elastic member or the second elastic member for supporting an object to be supported, wherein the first elastic member and the second elastic member are capable of being elastically deformed when the supporting portion supports the object to be supported, and elastic deformation amounts of the first elastic member and the second elastic member are different.
The foot pad assembly comprises a first elastic piece and a second elastic piece. The first elastic piece is provided with a first accommodating cavity, so that the second elastic piece can be arranged in the first accommodating cavity and is attached to the inner wall of the first accommodating cavity. It will be appreciated that the first and second elastic members are similar to a nested arrangement, the first elastic member being disposed on the outside and the second elastic member being disposed on the inside. When the supporting part is stressed to support the supported object, vibration reduction can be realized through the first elastic part and the second elastic part, so that the supported object is prevented from being damaged by strong vibration. Because the first elastic piece and the second elastic piece can elastically deform along the direction of the stress when the first elastic piece and the second elastic piece are stressed, and the elastic deformation amounts generated by the first elastic piece and the second elastic piece are different, tiny displacement can be generated between the first elastic piece and the second elastic piece, namely, one of the first elastic piece and the second elastic piece can elastically deform first, so that tiny friction is generated between the two elastic pieces, and accordingly vibration energy can be dissipated, and the vibration reduction effect is improved. It will be appreciated that the frequency of vibration is relatively high, and therefore the number of friction between the two elastic members is relatively high, so that vibration energy can be effectively reduced by using friction between the two elastic members. Compared with the scheme that the elastic parts of the foot pad assembly are of an integrated structure or the scheme that the reinforcing structure is arranged in the related art, the application utilizes friction generated by mutual movement of two objects, so that vibration energy is reduced by friction resistance, and the energy of vibration is effectively reduced.

Detailed Description
In order that the above-recited objects, features and advantages of the present application will be more clearly understood, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, without conflict, the embodiments of the present application and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
A foot pad assembly, a compressor and a refrigeration device according to some embodiments of the present invention are described below with reference to fig. 1-9.
According to one embodiment of the first aspect of the present invention, as shown in fig. 1, 2, 3, 4,5, 6, 8, 9, the first aspect of the present invention proposes a foot pad assembly 1 comprising a first resilient element 10 and a second resilient element 12. The first elastic member 10 has a first receiving chamber 100. The second elastic member 12 is disposed in the first accommodating cavity 100 and is attached to an inner wall of the first accommodating cavity 100. The support part 102 is arranged on the first elastic member 10 or the second elastic member 12 and is used for supporting the supported object, when the support part 102 supports the supported object, the first elastic member 10 and the second elastic member 12 can elastically deform, and the elastic deformation amounts of the first elastic member 10 and the second elastic member 12 are different.
The present application provides a foot pad assembly 1 comprising a first resilient member 10 and a second resilient member 12. The first elastic member 10 has a first receiving chamber 100 so that the second elastic member 12 can be disposed in the first receiving chamber 100 and is fitted to the inner wall of the first receiving chamber 100. It will be appreciated that the first elastic member 10 and the second elastic member 12 are arranged similarly to a nested arrangement, the first elastic member 10 being arranged on the outside and the second elastic member 12 being arranged on the inside. When the supporting portion 102 is force-supported by the supported object, vibration reduction can be achieved by the first elastic portion 120 and the second elastic portion 122, thereby preventing the supported object from being damaged by strong vibration. Because the first elastic member 10 and the second elastic member 12 can elastically deform in the direction of the stress when they are stressed, and the elastic deformation amounts generated by the first elastic member 10 and the second elastic member 12 are different, a tiny displacement is generated between the first elastic member 10 and the second elastic member 12, that is, one of the first elastic member 10 and the second elastic member 12 is elastically deformed, so that a tiny friction is generated between the two elastic members, and therefore, the energy dissipation of vibration is realized, and the vibration reduction effect is improved. It will be appreciated that the frequency of vibration is relatively high, and therefore the number of friction between the two elastic members is relatively high, so that vibration energy can be effectively reduced by using friction between the two elastic members. Compared with the scheme that the elastic parts of the foot pad assembly 1 are of an integrated structure or the scheme that the reinforcing structure is arranged in the related art, the application utilizes friction generated by mutual movement of two objects, so that vibration energy is reduced by friction resistance, and the energy of vibration is effectively reduced.
Meanwhile, since the supporting part 102 is arranged on the first elastic piece 10 or the second elastic piece 12, one of the first elastic piece 10 and the second elastic piece 12 can be ensured to bear the force generated by vibration, so that the elastic deformation of the one of the first elastic piece 10 and the second elastic piece 12 is ensured, and the tiny displacement can be generated relative to the other of the first elastic piece 10 and the second elastic piece 12, thereby realizing friction reduction of vibration energy.
In some embodiments, optionally, the supported object comprises a compressor 2.
In some embodiments, the first elastic member 10 may optionally have a hardness greater than the second elastic member 12.
In this embodiment, the first elastic member 10 has a hardness greater than that of the second elastic member 12. Therefore, when the first elastic member 10 is stressed and elastically deformed to a certain extent, the second elastic member 12 which is softer can be driven to elastically deform, so that the vibration energy can be reduced more advantageously.
In some embodiments, the second resilient member 12 optionally includes a second receiving chamber 126, and the footpad assembly 1 further includes a securing member 14 disposed within the second receiving chamber 126 for securing the first resilient member 10 and the second resilient member 12 in an installed position.
In this embodiment, the second resilient member 12 includes a second receiving cavity 126. The foot pad assembly 1 includes a fastener 14. Thus, the fixing element 14 can be arranged in the second accommodating cavity 126 and pass through the second accommodating cavity 126 and the first accommodating cavity 100, so that the first elastic element 10 and the second elastic element 12 are fixed at the installation position by using the second fixing element 14, and the installation stability of the foot pad assembly 1 is improved. Further, since the fixing member 14 is disposed in the second accommodating chamber 126, the strength of the second elastic member 12 can be reinforced by the fixing member 14, thereby improving the stability of the second elastic member 12.
In some embodiments, the first receiving chamber 100 may optionally include a first hole section 1000 and a second hole section 1002, the first hole section 1000 having an inner diameter larger than an inner diameter of the second hole section 1002, an inner wall of the second hole section 1002 being abutted against an outer wall of a circumferential side of the fixing member 14, the outer wall of the fixing member 14 and the inner wall of the first hole section 1000 forming the installation space 104, the second elastic member 12 being disposed in the installation space 104.
In this embodiment, the first receiving cavity 100 includes a first bore section 1000 and a second bore section 1002. The inner diameter of the first hole section 1000 is larger than the inner diameter of the second hole section 1002, that is, the first receiving chamber 100 is formed as a stepped hole. When the fixing member 14 is mounted in the second accommodation chamber 126, the inner wall of the second hole section 1002 abuts against the outer wall of the circumferential side of the fixing member 14, that is, the portion of the fixing member 14 which protrudes out of the second accommodation chamber 126 is disposed in the second hole section 1002. Since the inner diameter of the first hole section 1000 is larger than the inner diameter of the second hole section 1002, when the inner wall of the second hole section 1002 abuts against the outer wall of the circumference side of the fixing member 14, the installation space 104 is formed between the inner wall of the first hole section 1000 and the outer wall of the fixing member 14, and the second elastic member 12 can be disposed in the installation space 104. It can be appreciated that by defining the installation space 104, the second elastic member 12 is conveniently disposed, for example, a liquid material can be injected into the installation space 104 in an injection molding manner, and the second elastic member 12 is formed after solidification, so that the second elastic member 12 with various shapes is more beneficial to be formed, and thus, the stress requirement can be met maximally in practical application.
In practice, as shown in fig. 3, the fixing sleeve 140 may be first installed in the first accommodating cavity 100, and after the fixing sleeve 140 is matched with the first elastic member 10, a closed installation space 104 is formed, and liquid silicone rubber may be injected into the closed installation space 104 through an opening above the first elastic member 10, and after the liquid silicone rubber is solidified, a second elastic member 12 is formed in the installation space 104. The second elastic member 12 is not adhered to the inner wall of the cavity, so that a small displacement exists between the first elastic member 10 and the second elastic member 12, and vibration energy generated during operation of the compressor 2 can be dissipated through the small displacement between the first elastic member 10 and the second elastic member 12.
In some embodiments, the second elastic member 12 is optionally an injection molded member, and the shape of the injection molded member is adapted to the shape of the installation space 104.
In this embodiment, the second elastic member 12 may be provided as an injection-molded member. The injection molding piece is easy to process, convenient to set and high in design flexibility, and can form structures in various shapes, so that the actual use requirements can be met to the greatest extent.
In some embodiments, the securing member 14 optionally includes a securing sleeve 140 disposed within the second receiving chamber 126, and a securing screw 142 disposed within the securing sleeve 140.
In this embodiment, the securing member 14 includes a securing sleeve 140 and a securing screw 142. The fixing sleeve 140 is disposed in the second accommodating chamber 126, and is capable of restraining the first elastic member 10 and the second elastic member 12 in a radial direction of the second accommodating chamber 126 to limit the first elastic member 10 and the second elastic member 12. The fixing screw 142 is disposed within the fixing sleeve 140 such that the fixing screw 142 passes through the fixing sleeve 140 to fix the first elastic member 10 and the second elastic member 12 in the mounted position.
As shown in fig. 8 and 9, the lower end surface of the fixing screw 142 contacts with the upper end surface of the fixing sleeve 140, and after the fixing screw 142 is locked on the refrigerator bottom plate 3, the fixing screw 142 fixes the fixing sleeve 140 on the refrigerator bottom plate. The top of the fixing sleeve 140 is 0.2mm higher than the top of the first elastic member 10 and the second elastic member 12, so that the fixing screw 142 does not directly contact the first elastic member 10 and the second elastic member 12 after being locked, and the fixing screw 142 does not generate pressure on the foot pad assembly 1 in the vertical direction. As can be seen from fig. 9, the fixing screw 142 does not directly lock the foot pad assembly 1, the fixing screw 142 only plays a role of locking the fixing sleeve 140, and the fixing sleeve 140 generates a horizontal constraint on the first elastic member 10 and the second elastic member 12, but does not have a constraint on the vertical direction of the first elastic member 10 and the second elastic member 12.
In some embodiments, optionally, in the first direction, the length of the first elastic member 10 and the length of the second elastic member 12 are both smaller than the length of the fixing sleeve 140, and one end of the fixing sleeve 140 protrudes out of the first receiving cavity 100 and the second receiving cavity 126.
In this embodiment, the length of the first elastic member 10 and the length of the second elastic member 12 are smaller than the length of the fixing sleeve 140 in the first direction, and one end of the fixing sleeve 140 extends out of the first accommodating cavity 100 and the second accommodating cavity 126, that is, the fixing sleeve 140 needs to protrude out of the first elastic member 10 and the second elastic member 12, so that when the fixing screw 142 is used for fixing, the fixing sleeve 140 can limit the fixing force, so that the force generated by the fixing screw 142 acts on the first elastic member 10 and the second elastic member 12, and the elasticity of the first elastic member 10 and the second elastic member 12 is ensured.
In some embodiments, optionally, the extension of the fixation sleeve 140 is greater than or equal to 0.2mm.
In this embodiment, the protruding length of the fixing sleeve 140 is 0.2mm or more. This arrangement can ensure that the force generated when the fixing screw 142 is fixed does not act on the first elastic member 10 and the second elastic member 12, and can also avoid waste of materials, thereby reducing the cost.
In some embodiments, the extension of the fixation sleeve 140 is optionally 0.2mm.
In some embodiments, the extension of the fixation sleeve 140 is optionally 0.4mm.
In some embodiments, the extension of the fixation sleeve 140 is optionally 0.6mm.
In some embodiments, the support 102 may be optionally provided on the first elastic member 10, and the support 102 may include a support groove 1020 provided at a circumferential side of an outer surface of the first elastic member 10 for cooperating with the supported object to support the supported object.
In this embodiment, the support 102 is provided on the first elastic member 10, and the support 102 may be a support groove 1020. The support groove 1020 is provided at a circumferential side of the outer surface of the first elastic member 10, and can be engaged with the supported object, thereby supporting the supported object. Specifically, the mounting hole may be provided on the supported object, and then the supporting groove 1020 may be clamped into the mounting hole, thereby achieving the fixation of the foot pad assembly 1 and the supported object.
As shown in fig. 9, the base 20 of the compressor 2 is directly installed on the supporting groove 1020, and vibration generated when the compressor 2 is operated is attenuated by the foot pad assembly 1 and then transferred to the refrigerator bottom plate 3.

Wherein, the second through hole 1262 is disposed on the second elastic portion 122. The first elastic member 10 includes a fixing groove 106. The fixing groove 106 is provided on an inner wall of the first receiving chamber 100, and the first elastic portion 120 and the annular bead 124 are provided in the fixing groove 106. This kind of setting, through setting up second elasticity portion 122 and annular bead 124 to set up in the fixed slot 106 that first holds chamber 100, can make the second elastic component 12 set up more stable, especially when callus on the sole subassembly 1 atress is out of shape, can be more stable, guarantee the stability that first elastic component 10 and second elastic component 12 combination were used.

According to an embodiment of the first aspect of the present invention, a foot pad assembly 1 is provided and will be described taking the foot pad assembly 1 as an example for a refrigerator. The refrigerator includes a compressor 2 and a base plate provided with screw holes for fixing screws 142. The foot pad assembly 1 includes a rubber pad (first resilient member 10), silicone rubber (second resilient member 12), a bushing (fixing sleeve 140), and a fixing screw 142. The inner cavity of the rubber pad contains solidified silicon rubber, and extremely small friction can be carried out between the silicon rubber and the inner wall of the rubber pad cavity. The bushing is arranged in the through holes of the rubber pads and is limited by shrinkage holes between the rubber pads. The set screw 142 is used to lock the metal bushing to the refrigerator bottom plate 3. The compressor 2 vibrates the source, presses the whole on the four foot pad assemblies 1, and is positioned on the bottom plate through the fixing screws 142.
The foot pad assembly 1 is a rubber pad made of two materials, in this embodiment, the outer material is butyl rubber, the inner cavity is made of silica gel, the hardness of the silica gel is smaller than that of the butyl rubber, and in this embodiment, the silica gel in the cavity can be replaced by other materials softer than the outer material.
The inner cavity of the rubber pad is a closed area surrounded by the inner surface of the rubber pad and the outer surface of the metal bushing, liquid silicone rubber is injected into the cavity, and after the silicone rubber in the cavity is solidified, the whole closed area is filled, so that a set of supporting structure is formed in the original rubber pad.
The supporting structure is formed by solidifying liquid silica gel, the shape of the supporting structure is completely attached to the inner cavity of the rubber pad, but no adhesion exists between the supporting structure and the inner cavity of the rubber pad, so that when the external rubber pad is deformed due to vibration, the deformation of the internal silicon rubber is delayed from that of the external rubber, so that the two parts generate tiny displacement at the joint surface, the vibration energy is dissipated, and the technical effects of vibration reduction and noise reduction are realized.
The supporting structure is formed by solidifying liquid silica gel, the hardness of the supporting structure is smaller than that of external butyl rubber, as shown in fig. 7, when the inside of the butyl rubber pad is not filled with the silica gel supporting body, the supporting rigidity of the butyl rubber pad is mainly finished by the thin wall on the side surface of the butyl rubber pad, according to experience and the condition that the refrigerator system is easy to crush and deform under long-distance transportation and long-term operation, the hollow structure of the butyl rubber pad can have the risk of being crushed, and when the inside of the butyl rubber pad is filled with the silica gel supporting body, the axial supporting rigidity of the butyl rubber pad is obviously improved, so that the capability of resisting fatigue deformation and failure of the butyl rubber pad is stronger than that of the original hollow rubber pad.
The key points of the present application are specifically described below:
The application aims at solving the problems of deformation and crushing of an excessively soft foot pad in the long-term operation process of a refrigerator, and provides a foot pad assembly 1 suitable for a refrigerator compressor 2, wherein the foot pad assembly 1 is simple in structure, the installation method is the same as that of a common foot pad, and the vibration reduction and noise reduction capability and the deformation resistance are superior to those of the common rubber pad. The foot pad assembly 1 of the present application performs a glue injection process based on a general foot pad structure, and a cavity formed between an inner wall of a rubber pad (first elastic member 10) and a metal bushing (fixing sleeve 140) is filled with a silica gel material having a softer material. The silica gel material is liquid when not solidifying in the callus on the sole cavity, is soft silicone rubber of texture after solidifying, can keep the original soft characteristic of rubber pad to because rubber pad inside cavity is full of silicone rubber, the whole ability of resisting the deformation of rubber pad improves, consequently the rubber pad after carrying out the injecting glue is difficult for being crushed. And the inner wall of the rubber pad cavity and the silicon rubber in the cavity have tiny gaps, so that vibration energy generated during operation of the compressor 2 can be dissipated through tiny relative movement between the inner wall of the rubber pad cavity and the silicon rubber, and the effect of energy dissipation cannot be realized by a common single-material foot pad.
A second aspect of the present invention proposes a compressor 2 comprising a foot pad assembly 1 as in any of the embodiments of the first aspect.
According to the present application there is provided a compressor 2 comprising a foot pad assembly 1 according to any one of the embodiments of the first aspect. Since the compressor 2 includes the foot pad assembly 1 according to any embodiment of the first aspect, the compressor 2 provided by the present application further has all the beneficial technical effects of the foot pad assembly 1 according to any embodiment of the first aspect, which are not described in detail herein.
In some embodiments, the compressor 2 optionally comprises a reciprocating compressor.
In some embodiments, the reciprocating compressor optionally comprises a high speed reciprocating compressor.
The vibration and noise reduction principle of the compressor 2 will be described in detail as follows:
The compressor 2 is generally mounted on the bottom plate of the refrigerator system as a core component of the refrigerator system through a rubber pad at the bottom, specifically, the feet of the compressor 2 are welded with the shell thereof, and the feet are supported on the rubber pad, and the feet are only in contact and are not locked. The rubber pad generally has a through hole in the middle thereof, in which there is a small step shrinkage cavity for fixing the bushing of the compressor 2. The upper end of the bushing is contacted with a screw, the screw fixes the bushing on the bottom plate of the refrigerator system, and the locked bushing plays a role in positioning the rubber pad, so that the compressor 2 is ensured to keep a correct position in a compressor 2 cabin of the refrigerator system. Since the compressor 2 is operated to generate a dynamic vibration, the vibration is transmitted to the bottom plate of the refrigerator system through the rubber pad, thereby causing vibration and low-frequency noise of the refrigerator system, and fatigue damage of the system structure is also caused under long-term vibration.
Because the mounting structure between the rubber pad and the bushing of the compressor 2 ensures that the metal pieces are not in direct contact, vibration of the compressor 2 is transmitted to the metal bottom plate after being attenuated by the rubber material, and the contact area between the rubber material and the metal material is determined by the shrinkage cavity width in the rubber pad through hole. In the prior art, if the axial rigidity of the rubber pad is low, the rubber pad has strong capability of inhibiting low-frequency noise of the refrigerator system. However, since the mass of the compressor 2 is entirely supported by the rubber pad, the excessively soft rubber pad may be deformed or even crushed during the long-term operation of the refrigerator, thereby resulting in a reduction in vibration and noise reduction effects.
A third aspect of the invention proposes a refrigeration appliance comprising a foot pad assembly 1 as in any of the embodiments of the first aspect, and/or a compressor 2 as in the embodiments of the second aspect.
According to the present application there is provided a refrigeration appliance comprising a footpad assembly 1 in accordance with any of the embodiments of the first aspect and/or a compressor 2 in accordance with the embodiments of the second aspect. Since the refrigeration appliance includes the foot pad assembly 1 of any of the embodiments of the first aspect and/or the compressor 2 of the second aspect. Therefore, the refrigeration equipment provided by the application also has all the beneficial technical effects of the foot pad assembly 1 in any one embodiment of the first aspect and/or the compressor 2 in the embodiment of the second aspect, which are not described in detail herein.
In some embodiments, optionally, the refrigeration device includes a refrigerator, ice bin, or the like.
