Description

Technical Field

[0001] This utility model relates to the field of braking control technology, and in particular to a power controller. Background Technology

[0002] Power controllers are used for vehicle control. They control a joystick connected to a base, which in turn sends power adjustment commands. However, to ensure the joystick remains at the target rotation position, a damping plate is needed between the joystick and the base. The damping force of the plate keeps the joystick relative to the base at the target position. Because the damping plate is secured to the base with screws, the screw tightening pressure can be too high or too low, making it difficult to control the damping force. Some joysticks have excessive damping force, resulting in a heavy feel when turned, while others have insufficient damping force, leading to a light feel and a poor user experience.

The fixing component is fixedly connected to the rotating component and is located inside the housing. The elastic component is disposed inside the housing.

[0005] The fastener has a groove, and the elastic component includes an elastic element and a damping pad. The elastic element is disposed in the groove, and the damping pad is disposed between the elastic element and the housing and abuts against the housing.

[0006] The open end of the groove abuts against the damping pad or the housing to limit the amount of compression of the elastic element within the groove.

[0007] In the aforementioned power controller, by placing the elastic element within a groove and the damping pad between the elastic element and the housing, abutting against the housing, with the open end of the groove abutting against the damping pad or the housing, the compression of the elastic element within the groove is limited. This effectively controls the preload of the elastic element, i.e., effectively controls the damping force of the damping pad, enhancing the damping consistency between the elastic element and the damping pad. It also effectively addresses the issue of some joysticks having excessively large or small rotational damping, ensuring a good feel for joystick operation.

[0016] In some embodiments, the elastic component includes a sealing ring, and the circumferential sidewall of the second fixing part has an annular groove, with the sealing ring disposed within the annular groove.

[0017] In some embodiments, at least two of the sealing ring and the annular groove are provided, and at least two of the annular grooves are spaced apart along the axial direction of the rotating member on the circumferential sidewall of the second fixing part.

[0018] In some embodiments, the second connecting part has a screw hole, one end of the first connecting part is disposed in the screw hole, and the first connecting part is fixedly connected to the second connecting part through the screw hole.

[0034] Please refer to Figures 1 to 4 A power controller 100 according to an embodiment of the present invention includes a rocker arm 10, a rotating member 12, a housing 14, a fixing member 16, and an elastic component 18. One end of the rotating member 12 is fixedly connected to the rocker arm 10, and the other end of the rotating member 12 is rotatably connected to the housing 14 through the fixing member 16. The fixing member 16 is fixedly connected to the rotating member 12 and is located inside the housing 14. The elastic component 18 is disposed inside the housing 14. The fixing member 16 has a groove 20. The elastic component 18 includes an elastic member 22 and a damping pad 24. The elastic member 22 is disposed inside the groove 20, and the damping pad 24 is disposed between the elastic member 22 and the housing 14 and abuts against the housing 14. The open end of the groove 20 abuts against the damping pad 24 or the housing 14 to limit the compression of the elastic member 22 inside the groove 20.

[0035] In the aforementioned power controller 100, by placing the elastic element 22 in the groove 20 and the damping pad 24 between the elastic element 22 and the housing 14 and abutting against the housing 14, the opening end of the groove 20 abuts against the damping pad 24 or the housing 14, limiting the compression amount of the elastic element 22 in the groove 20, thereby effectively controlling the preload of the elastic element 22, that is, effectively controlling the damping force of the damping pad 24, enhancing the damping consistency between the elastic element 22 and the damping pad 24, and effectively ensuring the feel of the joystick 10 operation by preventing the rotation damping of the joystick 10 from being too large or too small.

[0036] Specifically, one end of the rocker arm 10 can be fixedly connected to the rotating member 12, and the other end can be used for user operation. One end of the rotating member 12 is fixedly connected to the rocker arm 10, and the other end of the rotating member 12 is rotatably connected to the housing 14 through the fixing member 16. The fixing member 16 includes screws, and the fixing member 16 is fixedly connected to the rotating member 12. The fixing member 16 can be provided inside the housing 14.

[0037] A groove 20 may be formed on one side of the fixing member 16, with the opening of the groove 20 facing the rotating member 12. The elastic member 22 includes a butterfly-shaped washer, and the elastic member 22 may be disposed within the groove 20. Figure 2 In the illustrated embodiment, a damping pad 24 is disposed between the elastic member 22 and the housing 14. One side of the damping pad 24 abuts against the opening end of the groove 20, and the other side abuts against the housing 14. The opening end of the groove 20 abuts against the damping pad 24, and one end of the elastic member 22 abuts against the bottom of the groove 20, while the other end abuts against the damping pad 24. This limits the compression of the elastic member 22 within the groove 20, thereby effectively controlling the preload of the elastic member 22, i.e., effectively controlling the damping force of the damping pad 24. This enhances the damping consistency between the elastic member 22 and the damping pad 24, effectively preventing the rotational damping of the rocker arm 10 from being too large or too small, and ensuring the feel of the rocker arm 10 during operation. The damping pad 24 includes a POM (polyoxymethylene) pad.

[0038] In other embodiments, the open end of the groove 20 may abut against the housing 14, the elastic member 22 is located in the groove 20, and the damping pad 24 is located in the groove 20, such that one end of the elastic member 22 abuts against the bottom of the groove 20 and the other end abuts against the damping pad 24, thereby limiting the amount of compression of the elastic member 22 in the groove 20.

[0039] Please combine Figure 4 In some embodiments, the length of the elastic element 22 is equal to the depth of the groove 20.

[0040] In this way, the amount of compression of the elastic element 22 within the groove 20 can be limited.

[0041] Specifically, in one embodiment, the damping pad 24 can cover the groove 20, allowing the elastic member 22 to be compressed within the groove 20. One end of the elastic member 22 abuts against the bottom of the groove 20, and the other end abuts against the damping pad 24, such that the length L of the elastic member 22 is equal to the depth H of the groove 20, thereby limiting the amount of compression of the elastic member 22 within the groove 20. The length L of the elastic member 22 is the distance from the end of the elastic member 22 abutting against the bottom of the groove 20 to the end abutting against the damping pad 24 when the elastic member 22 is in the compressed state.

[0042] Please combine Figures 2 to 4 In some embodiments, the fixing member 16 includes a first fixing part 26 and a first connecting part 28. The first fixing part 26 has a groove 20 on the side facing the rotating member 12. The first connecting part 28 is connected to the bottom of the groove 20 and the rotating member 12. The elastic member 22 and the damping pad 24 are both sleeved on the first connecting part 28.

[0043] Thus, by providing the first fixing part 26 and the first connecting part 28, the groove 20 can be formed in the first fixing part 26, and the elastic member 22 and the damping pad 24 can be fitted onto the first connecting part 28.

[0044] Specifically, the first fixing part 26 has a groove 20 on the side facing the rotating part 12, one end of the first connecting part 28 is connected to the bottom of the groove 20, and a thread is provided on the periphery near the other end. The first connecting part 28 can be threaded to the rotating part 12. The elastic member 22 is located in the groove 20, and the damping pad 24 covers the groove 20. Both the elastic member 22 and the damping pad 24 are sleeved on the first connecting part 28.

[0045] Please combine Figure 2 and Figure 3In some embodiments, the housing 14 has a first mounting groove 30 and a second mounting groove 32, which are respectively located on opposite sides of the housing 14. The rotating member 12 includes a second fixing part 34 and a second connecting part 36. The second fixing part 34 is connected to the second connecting part 36. One end of the second fixing part 34 is disposed in the first mounting groove 30, and the other end of the second fixing part 34 is connected to the rocker arm 10. A portion of the second connecting part 36 is located in the first mounting groove 30, and the other portion of the second connecting part 36 extends through the bottom of the first mounting groove 30 into the second mounting groove 32. The elastic member 22, the damping pad 24, and the first fixing part 26 are located in the second mounting groove 32, and the first connecting part 28 is connected to the second connecting part 36.

[0046] Thus, the first mounting groove 30 can be used to connect the rotating part 12 to the housing 14, and the second mounting groove 32 can be used to connect the fixing part 16 to the rotating part 12.

[0047] Specifically, a first mounting groove 30 is provided on the side of the housing 14 facing the rocker arm 10, and a second mounting groove 32 is provided on the side of the housing 14 opposite to the first mounting groove 30. In one embodiment, a second connecting part 36 is connected to the side of the second fixing part 34 facing the housing 14. One end of the second fixing part 34 is disposed in the first mounting groove 30, and the other end of the second fixing part 34 is connected to the rocker arm 10. A portion of the second connecting part 36 is located in the first mounting groove 30, and the other portion of the second connecting part 36 extends through the bottom of the first mounting groove 30 into the second mounting groove 32. The elastic member 22, the damping pad 24, and the first fixing part 26 are located in the second mounting groove 32. The first connecting part 28 is connected to the second connecting part 36. Thus, the connection between the rotating member 12 and the housing 14 can be realized through the first mounting groove 30, and the connection between the fixing member 16 and the rotating member 12 can be realized through the second mounting groove 32.

[0048] Please combine Figure 2 and Figure 3 In some embodiments, the bottom of the first mounting groove 30 has a protrusion 38, the protrusion 38 has a through hole 40, the through hole 40 communicates with the second mounting groove 32, and the second connecting part 36 extends into the second mounting groove 32 through the through hole 40.

[0049] Thus, the second connecting part 36 extends through the through hole 40 into the second mounting groove 32, and the first connecting part 28 can be connected to the second connecting part 36.

[0050] Specifically, a protrusion 38 is provided at the middle position of the first mounting groove 30, and a through hole 40 can be opened at the middle position of the top of the protrusion 38, which connects to the second mounting groove 32. In one embodiment, when one end of the second fixing part 34 is inserted into the first mounting groove 30, one end of the second fixing part 34 can abut against the protrusion 38, and the second connecting part 36 extends into the second mounting groove 32 through the through hole 40, and the first connecting part 28 can be connected to the second connecting part 36.

[0051] Please combine Figure 3 In some embodiments, a connecting groove 42 is provided at one end of the second fixing part 34, and the second connecting part 36 is connected to the bottom of the connecting groove 42.

[0052] Thus, when one end of the second fixing part 34 is inserted into the first mounting groove 30, the protrusion 38 can be located in the connecting groove 42, thereby making the second fixing part 34 and the protrusion 38 fit together.

[0053] Specifically, a connecting groove 42 may be provided on the side of the second fixing part 34 facing the housing 14, and the second connecting part 36 is connected to the bottom of the connecting groove 42. In one embodiment, when one end of the second fixing part 34 is inserted into the first mounting groove 30, the protrusion 38 may be located in the connecting groove 42, thereby making the second fixing part 34 and the protrusion 38 fit together.

[0054] Please combine Figure 3 In some embodiments, the elastic component 18 includes a connecting gasket 44 disposed at the bottom of the connecting groove 42 and fitted onto the second connecting portion 36.

[0055] Thus, by setting the connecting gasket 44, the rotating part 12 and the housing 14 are made to achieve a damped connection.

[0056] Specifically, the connecting gasket 44 includes a POM gasket. In one embodiment, the connecting gasket 44 is disposed at the bottom of the connecting groove 42 and sleeved on the second connecting part 36. When one end of the second fixing part 34 is inserted into the first mounting groove 30, one side of the connecting gasket 44 can be driven to abut against the protrusion 38, thereby enabling the rotating member 12 and the housing 14 to achieve a damped connection.

[0057] Optionally, in Figure 3 In the middle, the top of the protrusion 38 may be provided with a receiving groove 46, and the connecting gasket 44 may be disposed in the receiving groove 46.

[0058] Please combine Figure 3 In some embodiments, the elastic component 18 includes a sealing ring 48, and the circumferential sidewall of the second fixing part 34 is provided with an annular groove 50, and the sealing ring 48 is disposed in the annular groove 50.

[0059] This prevents external debris from entering the first mounting groove 30 through the gap between the second fixing part 34 and the housing 14.

[0060] Specifically, the sealing ring 48 includes a star-shaped ring, and an annular groove 50 can be formed on the circumferential sidewall of the second fixing part 34 near the second connecting part 36, and the sealing ring 48 is disposed in the annular groove 50. In one embodiment, when one end of the second fixing part 34 is inserted into the first mounting groove 30, the sealing ring 48 is located in the annular groove 50 and disposed between the second fixing part 34 and the housing 14, thereby preventing external debris from entering the first mounting groove 30 through the gap between the second fixing part 34 and the housing 14.

[0061] Please combine Figure 3 In some embodiments, at least two sealing rings 48 and annular grooves 50 are provided, and at least two annular grooves 50 are spaced apart on the circumferential sidewall of the second fixing part 34 along the axial direction of the rotating member 12.

[0062] This can further improve the sealing between the rotating part 12 and the housing 14.

[0063] Specifically, the rotating part 12 may be cylindrical, and the circumferential sidewall of the second fixing part 34 is provided with at least two annular grooves 50. The at least two annular grooves 50 are spaced apart along the axial direction of the rotating part 12, and each annular groove 50 is provided with a sealing ring 48, which can further improve the sealing between the rotating part 12 and the housing 14.

[0064] Please combine Figure 3 In some embodiments, the second connecting part 36 is provided with a screw hole 52, and one end of the first connecting part 28 is disposed in the screw hole 52. The first connecting part 28 is fixedly connected to the second connecting part 36 through the screw hole 52.

[0065] Thus, one end of the first connecting part 28 can be placed inside the screw hole 52, thereby achieving a fixed connection with the second connecting part 36.

[0066] Specifically, the second connecting part 36 has a screw hole 52 at one end opposite to the second fixing part 34, and the first connecting part 28 has a thread. One end of the first connecting part 28 can be placed in the screw hole 52, thereby achieving a fixed connection with the second connecting part 36.

[0067] In some embodiments, the power controller 100 also includes a Hall sensor (not shown) and a magnet (not shown) is fixed on the fixture 16. The Hall sensor senses the amount of rotation of the rocker arm 10 by sensing the magnet.

[0068] In this way, the rotation of the sensing joystick 10 can be calculated.

[0069] Specifically, in one embodiment, a Hall sensor can be mounted on the housing 14, and a magnet can be mounted on the first fixing part 26. The Hall sensor can sense the rotation of the rocker arm 10 by sensing the magnet, and thus can calculate the rotation of the rocker arm 10.

[0070] In some embodiments, the power controller 100 further includes a zero-position damping structure (not shown) for positioning the rocker arm 10 in the zero position, when the rocker arm 10 is in the zero position to control the power controller 100 in the neutral state.

[0071] Thus, by setting the zero position through the zero-position damping structure, the power controller 100 can be controlled to be in neutral.

[0072] Specifically, a zero-position damping structure can be provided on the housing 14. In one embodiment, when it is necessary to put the power controller 100 in a neutral state, the rocker arm 10 can be positioned to the zero position, thereby controlling the power controller 100 to be in a neutral state.
