The electronic device 200 of the present invention includes an electronic body and the input device 100 of the present invention. The electronic body is, for example, a laptop, a keyboard, a presentation pen, a mobile phone, a tablet computer, a game joystick or a mouse. In one embodiment of the present invention, the input device 100 can be used as a controller of a mouse cursor, and the user can control the mouse cursor by operating the input device 100, that is, the user can replace a traditional mouse by operating the input device 100. In different embodiments, the electronic device 200 may not include the display 202, and the electronic device 200 only serves as a wireless or wired keyboard. It should be noted that the input device 100 of the present invention can be installed on various electronic devices according to needs, not limited to the above. For example, the input device 100 can also be installed on a mouse, a presentation pen, a tablet computer, a game joystick, and other electronic devices that require direction or cursor control.

The input device 100 of the invention comprises a substrate 1, a supporting structure 2, four magnetic sensors 3, a processor 4, an elastic reset structure 5, a cover 6 and a magnetic member 7. The number of magnetic sensors 3 and magnetic members 7 included in the input device 100 can be varied according to actual needs and is not limited to those shown in the figure.

The substrate 1 serves as a fixed base plate. One end of the support structure 2 is fixed to the fixed base plate. In the present embodiment, the support structure 2 is exemplified by a cylindrical structure, but the appearance of the support structure 2 is not limited thereto. The substrate 1 is, for example, an insulating plate. The substrate 1 includes, for example, a fixed base plate 10 and a flexible circuit board 11. The fixed base plate 10 is, for example, an insulating board. The flexible circuit board 11 is fixedly disposed on the fixed base plate 10. Four magnetic sensors 3 and a processor 4 are fixedly disposed on the flexible circuit board 11. In different embodiments, the substrate 1 may also be a hard printed circuit board, a metal plate or a plastic plate. The processor 4 is electrically connected to the four magnetic sensors 3. Each magnetic sensor 3 is used to sense the change of magnetic force and generate a sensing signal accordingly. The processor 4 can receive the sensing signal transmitted by each magnetic sensor 3. In practical applications, two of the magnetic sensors 3 are located on a first axis L1, and the other two magnetic sensors 3 can be located on a second axis L2. The first axis L1 is not parallel to the second axis L2, and the first axis L1 can be perpendicular to the second axis L2.

In the embodiment where the input device 100 includes only two magnetic sensors 3, one of the magnetic sensors 3 may be located on the first axis L1, and the other magnetic sensor 3 may be located on the second axis L2. In a variation of the embodiment where the input device 100 includes only two magnetic sensors 3, the two magnetic sensors 3 may also be arranged on the same axis.

The elastic return structure 5 is disposed on the substrate 1, and the elastic return structure 5 is sleeved on one end of the support structure 2 fixed to the substrate 1. The elastic return structure 5 is an elastic structure, and when the elastic return structure 5 is compressed, it can be elastically deformed. For example, the elastic return structure 5 can be made of elastic materials such as rubber, silicone, foam, plastic, etc., but not limited thereto. In practice, the shape of the elastic return structure 5 can be, for example, a ring, but not limited thereto.

One side of the cover 6 is fixed to the other end of the support structure 2. A bottom surface 61 of the cover 6 facing the substrate 1 abuts against the elastic return structure 5. When the cover 6 is operated by the user on the side opposite to the side facing the substrate 1 and moves toward the substrate 1, the bottom surface 61 of the cover 6 will exert a force on the elastic return structure 5, thereby causing the elastic return structure 5 to produce a greater elastic deformation. When the cover 6 is no longer operated by the user, the elastic restoring force generated by the pressure on the elastic return structure 5 will restore the cover 6 to the position when it is not operated by the user.

The magnetic member 7 may be, for example, a ring-shaped structure, and the magnetic member 7 may be embedded in the cover 6, and each magnetic sensor 3 is located in the area of the positive projection of the magnetic member 7 in the direction of the substrate 1, that is, the area directly above each magnetic sensor 3 corresponds to at least a portion of the magnetic member 7. The magnetic member 7 and the cover 6 may be manufactured by insert molding.

In different embodiments of the present invention, the input device 100 may also include four magnetic members 7, which are respectively embedded in the cover 6. It should be noted that as long as the top of the four magnetic sensors 3 can correspond to a portion of one of the magnetic members 7, the number of magnetic members 7 can be changed according to demand. For example, in another embodiment, the input device 100 may also include two magnetic members 7, which are embedded in the cover 6, and the top of each magnetic sensor 3 faces a portion of one of the magnetic members 7.

In the above description, the magnetic component 7 is buried in the cover body 6 as an example, but the fixing method of the magnetic component 7 and the cover body 6 is not limited to this. In different embodiments, the bottom surface 61 of the cover body 6 can be concave to form an annular groove, and the width of the annular groove is, for example, slightly smaller than the width of the magnetic component 7, and the magnetic component 7 is snap-fitted and fixed in the annular groove. In different embodiments, the magnetic component 7 can also be fixed to the cover body 6 using adhesive. The appearance and size of each magnetic component 7 can be changed according to actual needs. The position where multiple magnetic components 7 are arranged on the cover body 6 can also be changed according to needs.

When the cover 6 is not operated by the user, there is a gap G between the magnetic member 7 and each magnetic sensor 3 to provide the cover 6 with movement. Specifically, when the cover 6 is fixed to one side of the substrate 1 through the support structure 2, the bottom surface 61 of the cover 6 will abut against the elastic reset structure 5, thereby forming the gap G between the bottom surface 61 of the cover 6 and the magnetic sensor 3.

It is worth mentioning that, in practical applications, the height of the elastic reset structure 5 when not under pressure is a first height. The bottom surface 61 of the cover 6 is at a second height H relative to the substrate 1, the first height is greater than the second height H, and the elastic reset structure 5 is elastically deformed when pressed by the cover 6. In more detail, the support structure 2 may include a head 21 and a neck 22, the outer diameter 21D of the head 21 is greater than the outer diameter 22D of the neck 22. The cover 6 has a snap-fit groove 63, the snap-fit groove 63 includes a first accommodating section 631 and a second accommodating section 632, the inner diameter 631D of the first accommodating section 631 is greater than the inner diameter 632D of the second accommodating section 632. The first accommodating section 631 and the head 21 are engaged with each other, and the second accommodating section 632 and the neck 22 are engaged with each other. Through the design of the first accommodating section 631, the second accommodating section 632, the head 21 and the neck 22, the range of movement of the cover 6 relative to the supporting structure 2 can be limited, and the side of the cover 6 facing the substrate 1 (i.e., the bottom surface 61) presses against the elastic return structure 5, so that the elastic return structure 5 is slightly elastically deformed. In short, when the input device 100 is installed and the cover 6 is not operated by the user, the elastic return structure 5 can be in a slightly elastically deformed state.

When the cover 6 is operated by the user, the magnetic member 7 will move along with the cover 6, and a part of the magnetic member 7 will approach the adjacent magnetic sensor 3, whereby the magnetic sensor 3 will sense the change in magnetic force and generate a sensing signal accordingly. When the processor 4 receives the sensing signal, the processor 4 can generate a corresponding mouse control signal, and the processor 4 can transmit the mouse control signal to a computer, and the computer can control the cursor according to the mouse control signal. In the example where the input device 100 of the present invention does not include the processor 4, each magnetic sensor 3 can directly transmit the sensing signal to the computer, and the application running on the computer can convert the sensing signal into a mouse control signal to move the mouse cursor.

In this embodiment, the input device 100 includes four magnetic sensors 3, which can be used to sense the movement of the cover 6 in the +X axis direction, the -X axis direction, the +Y axis direction and the -Y axis direction, respectively, thereby controlling the cursor to move in the corresponding direction, that is, the input device 100 can control the cursor to move in the X-Y plane. In the example where the input device 100 includes two magnetic sensors 3 arranged on the same axis, the two magnetic sensors 3 can be used to sense the magnetic force changes of the cover 6 in the +X axis direction and the -X axis direction, or the two magnetic sensors 3 can be used to sense the magnetic force changes of the cover 6 in the +Y axis direction and the -Y axis direction. It is worth mentioning that since the magnetic sensor 3 is used to sense changes in magnetic force, the magnetic sensor 3 can generate corresponding sensing signals when the magnetic member 7 approaches or moves away from the magnetic sensor 3. The processor 4 or computer can determine the direction in which the cover 6 is operated based on the sensing signals, thereby controlling the moving direction of the mouse cursor.

In actual application, when the processor 4 determines based on the sensing signal that the cover 6 has been continuously pressed in the same direction for more than a preset time, or when the processor 4 determines based on the sensing signal that the cover has moved a distance exceeding a preset distance, the processor 4 may, for example, generate a corresponding fast movement control signal, and the computer may control the cursor to move quickly in one direction based on the fast movement control signal. The rapid movement referred to here is relative to the normal mouse movement speed; for example, assuming that the processor 4 determines based on the sensing signal that the cover 6 is continuously pressed in the same direction for more than 0.5 seconds (the preset time), the processor 4 will generate a rapid movement control signal, and the cursor will move quickly. Conversely, if the cover 6 is only operated for 0.1 seconds, the cursor will move relatively slowly.

For example, assuming that the processor 4 determines based on the sensing signal that the distance that the cover 6 moves relative to the magnetic sensor 3 exceeds 0.5 mm, the processor 4 may generate a corresponding fast movement control signal, and the cursor will move quickly. Conversely, if the distance that the cover 6 moves relative to the magnetic sensor 3 is less than 0.5 mm, the cursor will move at a normal speed.

As described above, the electronic device 200 and the input device 100 of the present invention, through the design of the cover 6, the elastic reset structure 5, the magnetic member 7 and the magnetic sensor 3, can allow the user to control the mouse cursor by operating the input device 100, and these designs can effectively reduce the overall size of the input device 100, so that the input device 100 can be installed on various keyboards, especially suitable for installation on a laptop keyboard. It should be noted that in the above description, the electronic device 200 mainly controls the mouse cursor according to the control signal transmitted by the input device 100, but it is not limited to this. In different embodiments, the electronic device 200 may also use the control signal as a direction function in a control application. For example, the application may be a game, and the user may control the character in the game to move in any direction such as left or right through the control input device 100 via an electronic device (such as a computer, tablet computer, mobile phone, etc.).

In addition, it should be noted that the input device 100 of the present invention can effectively improve the sensitivity of the magnetic sensor 3 in sensing the magnetic force changes caused by the different distances between the magnetic member 7 and the input device 100 by placing the magnetic sensor 3 in the area of the positive projection of the magnetic member 7 onto the substrate 1. In other words, if the magnetic sensor 3 is not placed in the area of the positive projection of the magnetic member 7 onto the substrate 1, the sensitivity of the magnetic sensor 3 in sensing the magnetic force changes caused by the different distances between the magnetic member 7 and the input device 100 will decrease.

As shown in FIG. 4 , since the input device 100 of the present invention utilizes an elastic return structure 5 to restore the cover 6 to an uncompressed state, and the input device 100 of the present invention is not provided with any compression spring, the vertical height Z between the top of the cover 6 of the input device 100 and the substrate 1 can be less than 4 mm, and the vertical height Z between the top of the cover 6 of the input device 100 and the substrate 1 can be approximately 3 mm.

It should be noted that in practice, the processor 4 may convert different control signals into corresponding ones when receiving different sensing signals, so that after the computer receives the control signal sent by the processor, it can control the cursor to achieve the effect of a single click or double click of a traditional mouse. For example, when the user presses the cover 6, and each magnetic sensor 3 senses a change in magnetic force almost at the same time, and the time for the change in magnetic force sensed by each magnetic sensor 3 is less than a preset time, then after the processor 4 receives the sensing signal transmitted by each magnetic sensor 3, it can be determined that the user is currently pressing the cover 6 briefly, thereby, the processor 4 can generate a corresponding mouse click control signal (for example, it can be equivalent to the control signal generated by a click of a traditional mouse), and after the computer receives the mouse click control signal, it can control the mouse cursor to complete the click action. Similarly, the processor 4 can also generate a mouse double-click control signal according to the sensing signals transmitted by each magnetic sensor 3. After receiving the mouse double-click control signal, the computer can control the mouse cursor to perform a double-click action.

Please refer to FIG. 6 and FIG. 7 , which are schematic top views of the third and fourth embodiments of the input device of the present invention. The embodiment shown in FIG. 6 is most different from the aforementioned embodiments in that the input device 100 includes three magnetic sensors 3, and the three magnetic sensors 3 are disposed at the three vertices of a virtual triangle T, and each magnetic sensor 3 is located within the range of the positive projection of the magnetic member 7 in the direction of the substrate 1. The processor 4 can receive the sensing signals transmitted by the three magnetic sensors 3, and control the movement of the cursor in the X-Y plane accordingly. The embodiment shown in FIG. 7 is most different from the aforementioned embodiments in that the input device 100 includes a plurality of magnetic sensors 3, which are disposed around the supporting structure 2.

Please refer to Fig. 8, which is a top view of the fifth embodiment of the input device of the present invention. The biggest difference between this embodiment and the above embodiments is that the input device 100 includes a single magnetic sensor 3 (located at the upper position in the figure and shown by a dotted line), and the input device 100 can only sense the movement of the cover 6 in a single axis. In actual application, the input device 100 of this embodiment can be installed on a traditional mouse and used to replace the scroll wheel of the traditional mouse; that is, when the user pushes the cover 6 forward, the control signal transmitted by the processor to the computer will be the same as the signal of the scroll wheel of the traditional mouse rolling forward, and vice versa, the control signal transmitted by the processor to the computer will be the same as the signal of the scroll wheel of the traditional mouse rolling backward. It should be noted that in one of the variant embodiments of FIG. 8 , the input device 100 can include two magnetic sensors 3 (located at the lower position in the figure and shown by imaginary lines), which are arranged on the same axis.

Please refer to FIG. 9 , which is a cross-sectional schematic diagram of the sixth embodiment of the input device of the present invention. The biggest difference between this embodiment and the aforementioned embodiments is that the input device 100 further includes an elastic auxiliary reset member 9. The elastic auxiliary reset member 9 is disposed between the cover 6 and the magnetic sensor 3. The elastic auxiliary reset member 9 is, for example, a ring-shaped elastic structure, but is not limited thereto. The elastic auxiliary reset member 9 is a non-magnetic structure.

When the cover 6 is under pressure, the cover 6 will resist the elastic auxiliary reset member 9, and the elastic auxiliary reset member 9 will be elastically deformed; when the cover 6 is no longer under pressure, the elastic restoring force generated by the elastic deformation of the elastic auxiliary reset member 9 will help the auxiliary cover 6 to return to a non-pressurized state. Through the design of the elastic auxiliary reset member 9, the cover 6 can be restored to a non-pressurized state more quickly when it is no longer under pressure. The appearance and number of the elastic auxiliary reset member 9 can be designed according to actual needs and are not limited here.

Please refer to Figure 10, which shows a cross-sectional schematic diagram of the seventh embodiment of the input device of the present invention. One of the differences between this embodiment and the aforementioned first embodiment is that the input device 100 can also be provided with a vertical substrate 10A, and the vertical substrate 10A is provided with a magnetic sensor. For the sake of explanation, the magnetic sensor provided on the vertical substrate 10A is defined as an auxiliary magnetic sensor 3A. The auxiliary magnetic sensor 3A is located in the area of the orthographic projection direction of the magnetic member 7 in the direction of the vertical substrate 10A. The support structure 2 can be a structure with elasticity, and the user can operate the cover 6 to move the cover 6 in a direction close to the auxiliary magnetic sensor 3A. With such a design, after the processor 4 receives the sensing signal transmitted by the auxiliary magnetic sensor 3A, it can determine whether the user moves the cover 6 toward or away from the auxiliary magnetic sensor 3A, thereby generating a corresponding control signal. For example, after the processor 4 receives the sensing signal transmitted by the auxiliary magnetic sensor 3A, the control signal generated can be the same as the control signal generated corresponding to the forward or backward scrolling of the scroll wheel of a traditional mouse. Of course, the number and location of the vertical substrate 10A and the auxiliary magnetic sensor 3A can be changed according to actual needs, and are not limited to the above description and the figures. It should be noted that in different embodiments, the support structure 2 and the substrate 1 can be connected to each other using a sliding structure such as a slide rail, and the user can operate the cover 6 to move the cover 6 toward or away from the auxiliary magnetic sensor 3A.

Please refer to FIG. 11 , which is a partially exploded schematic diagram of the eighth embodiment of the input device of the present invention. The difference between the present embodiment and the aforementioned embodiments is that the magnetic sensor can be an annular magnetic sensor 3B, and the annular magnetic sensor 3B can include at least one magnetic induction coil. By packaging the magnetic induction coil into an annular magnetic sensor 3B, it is easy to assemble, which can reduce the assembly process and time, and can further reduce the overall volume of the input device.

In one variation of the present embodiment, the cover 6 may be provided with a plurality of magnetic members 7 , and the annular magnetic sensor 3B may be provided with a plurality of induction coils at positions corresponding to the plurality of magnetic members 7 .

In summary, the electronic device and input device of the present invention utilize the characteristics of magnetic induction, the closer the distance between the magnetic part and the magnetic sensor, the stronger the signal, and the elastic reset structure, so that the cover that is no longer under pressure is reset, instead of using a compression spring. Therefore, the overall volume of the input device can be greatly reduced, and the overall height of the input device can be less than 4 mm. In addition, by designing that the magnetic sensor is located within the range of the positive projection of the magnetic part onto the substrate, the sensing sensitivity of the magnetic sensor can be effectively improved.

The above is only the best feasible embodiment of the present invention and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the instructions and diagrams of the present invention are included in the protection scope of the present invention.
