[0031] Example 1

[0032] Please refer to Figures 1-6This utility model provides a control component for wearable and walking assistance devices, including a battery box 1, an adjustable bracket 2, and a servo motor 3. One end of the adjustable bracket 2 is movably connected to the battery box 1, and the adjustable bracket 2 is located on both sides of the battery box 1. The servo motor 3 is fixedly connected to the other end of the adjustable bracket 2. The battery box 1 provides power to the servo motor 3. The two ends of the battery box 1 are provided with through grooves 11 and limit buckles 12. One end of the adjustable bracket 2 moves telescopically along the through groove 11. The limit buckle 12 is located on one side of the through groove 11. When width adjustment is required, the limit buckle 12 is opened to retract the adjustable bracket 2 into or out of the through groove 11. When fixation is required, the limit buckle 12 is pressed down to stabilize the adjustable bracket 2.

[0033] Specifically, the limiting buckle 12 includes a mounting base 121, a rotating shaft 122, a lever block 123, and a movable block 124. The rotating shaft 122 passes through the lever block 123 and the mounting base 121, and the rotating shaft 122 houses the lever block 123 within the mounting base 121. The movable block 124 is located on one side of the mounting base 121, and the lever block 123 abuts against the movable block 124. The movable block 124 is movably abutting against the adjustable bracket 2. (Refer to...) Figure 3 An opening is provided between the mounting base 121 and the through groove 11, and the movable block 124 is disposed within the opening; (refer to...) Figure 5 The contact surface between the movable block 124 and the lever block 123 is arc-shaped, the contact surface between the movable block 124 and the adjustable bracket 2 is flat, and the contact part between the lever block 123 and the movable block 124 is an arc surface. The principle is as follows: when the adjustable bracket 2 is fixed, the most convex point on the arc surface of the lever block 123 abuts against the lowest point of the arc of the movable block 124, and the other flat surface of the movable block 124 can press against the adjustable bracket 2; when the adjustable bracket 2 is released, the most convex point on the arc surface of the lever block 123 is located above the lowest point of the arc of the movable block 124, that is, the holding force is released, and the flat surface of the movable block 124 does not need to contact the adjustable bracket 2.

[0034] In addition, regarding the detailed structural description of the servo unit 3: The servo unit 3 includes a permanent magnet synchronous motor 31, a planetary gear reducer 32, and several gears 33. The servo unit 3 is equipped with a power output arm 4. Both the permanent magnet synchronous motor 31 and the planetary gear reducer 32 have output shafts 311. The gears 33 are mounted on the output shafts 311, and the several gears 33 are meshed together. The output shaft 311 of the planetary gear reducer 32 is also connected to the power output arm 4. This structure is an integrated design, which simplifies the transmission structure. The permanent magnet synchronous motor 31 typically has high efficiency, and compared to other types of motors, it can more effectively convert electrical energy into mechanical energy, thereby extending the service life of the equipment. The permanent magnet synchronous motor 31 can provide greater torque within the same volume. Furthermore, it enables precise position, speed, and torque control, resulting in smoother movement of the equipment and improved user comfort and safety. The permanent magnet synchronous motor 31 operates with low noise, enhancing the user experience, especially when a quiet environment is required. Its simple structure, low wear, and relatively durable nature, coupled with low maintenance requirements, reduce the failure rate over long-term use. Due to its high efficiency, the permanent magnet synchronous motor 31 generates less heat, reducing system cooling requirements and improving system stability. Combined with the planetary gear reducer 32, it achieves high output torque within a smaller space, contributing to reduced overall equipment weight, ease of carrying and use, rapid start-up and stop response, real-time feedback to user actions, and improved operational flexibility.

[0035] Specifically, the gear 33 includes a motor gear 331, a transition gear 332, and a reducer gear 333. The motor gear 331 is connected to the output shaft 311 of the permanent magnet synchronous motor 31, and the reducer gear 333 is connected to the output shaft 311 of the planetary gear reducer 32. The transition gear 332 is located between the motor gear 331 and the reducer gear 333, that is, the motor gear 331 first meshes with the transition gear 332 to drive the reducer gear 333, and then the transition gear 332 meshes with the reducer gear 333 to drive the reducer gear 333.

[0036] The servo unit 3 also includes a drive PCB board 34 and a detection PCB board 35. The drive PCB board 34 is located above the motor gear 331, the transition gear 332 and the reducer gear 333. The drive PCB board 34 is electrically connected to the permanent magnet synchronous motor 31 and the planetary gear reducer 32. The detection PCB board 35 is located below the power output arm 4.

[0037] The servo unit 3 also includes a motor speed measuring magnet 36 and a power output arm speed measuring magnet 37. The motor speed measuring magnet 36 is electrically connected to the output shaft 311 of the permanent magnet synchronous motor 31, and the power output arm speed measuring magnet 37 is electrically connected to the output shaft 311 of the planetary gear reducer 32.

[0038] The surface of the servo unit 3 is provided with an assist adjustment button 38, which is electrically connected to the drive PCB board 34. The assist force can be adjusted by the assist adjustment button 38, and the user can adjust the assist force according to their gait and terrain to further meet the user's needs.

[0039] The servo unit 3 also includes a housing 39 and a mounting bracket 310. The motor gear 331, the reducer gear 333, and the transition gear 332 are all mounted on the mounting bracket 310. The mounting bracket 310 has a fixed shaft, and the transition gear 332 is mounted on the fixed shaft. The housing 39 encloses the mounting bracket 310, the motor gear 331, the reducer gear 333, the transition gear 332, the drive PCB board 34, the detection PCB board 35, the motor speed measuring magnet 36, and the power output arm speed measuring magnet 37. The housing 39 is made of high-strength engineering plastic material, which has good protective performance and can effectively prevent dust and moisture from entering, protecting the internal precision components.

[0040] The outer casing 39 is provided with a slot 391, and the power output arm 4 is movably disposed within the slot 391.

[0041] The surface of the battery box 1 is provided with a power button 13, which is used to start the control component.

[0042] Example 2

[0043] The difference from Embodiment 1 is that the limiting buckle 12 can be a spring button, which uses elasticity to extend and retract the button of the adjustable bracket 2, pressing or releasing the adjustable bracket 2.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent.
