Description

Technical Field

[0001] This invention relates to the field of assembly technology, and more specifically, to a brake assembly method and system. Background Technology

[0002] During the assembly of the brake, the installation of the caliper, bracket, brake pads, and return spring is generally done manually. The operator must first insert the brake pads (inner and outer pads) into the slots or claws of the bracket, then install the return spring, hooking its two ends into the insertion holes of the brake pads. Finally, the caliper with piston and seal is fitted onto the bracket and aligned with the mounting holes to complete the installation.

[0003] The sequential assembly of the aforementioned components still relies heavily on manual force applied by operators, revealing significant difficulties in actual production. Due to the compact space and complex fit between the calipers, brackets, brake pads, and return springs, and the considerable elasticity of the return springs, assembly is extremely difficult. This results in a time-consuming brake assembly process, a high degree of dependence on operator skill, and difficulty in ensuring assembly consistency, directly impacting the brake's return performance and driving safety. Summary of the Invention

The pre-installed reset unit includes a pair of insertion parts of the reset unit that are respectively inserted into the first and second brake pads, and a spring-loaded part of the reset unit that abuts against the limiting groove. The reset unit includes a pair of insertion parts, a pair of connecting parts, and a spring-loaded part. The two ends of the connecting parts are respectively connected to the insertion parts and the spring-loaded part, and the pair of connecting parts are respectively connected to the two ends of the spring-loaded part.

[0008] Based on the pre-installation of the reset unit, the drive assembly drives the first brake pad and the second brake pad to abut against the opposite sides of the pad limiting block, and at the same time drives the reset unit to deform, and the spring limiting block restricts the rebound part within the limiting groove.

[0009] The spring-limiting block restricts the rebound part within the limiting groove, thus completing the assembly of the bracket and caliper;

[0010] Once the bracket and caliper are assembled, the brake is detached from the base assembly.

[0013] Based on the pre-assembly of the bracket and the caliper, the first brake pad and the second brake pad are inserted into the bracket.

[0014] Optionally, based on the pre-installation of the reset unit, the drive assembly drives the first and second brake pads to abut against the opposite sides of the pad limiting block, while simultaneously deforming the reset unit. The spring limiting block restricts the rebound portion within the limiting groove, including:

[0015] Once the reset unit is pre-installed, the drive assembly drives the first brake pad to move to the first position and drives the second brake pad to move to the second position.

[0022] Optionally, the assembly of the bracket and caliper is completed by limiting the spring-loaded portion within the limiting groove based on the spring-loaded limiting block:

[0023] Based on the spring limit block restricting the rebound part within the limit groove, the caliper rotates around the pre-installed end of the caliper and presses against the bracket;

[0024] The caliper is pressed onto the bracket, and the caliper end to be assembled and the bracket end to be assembled are assembled to complete the assembly of the bracket and the caliper.

[0025] Optionally, based on the completion of the bracket and caliper assembly, the brake disengagement from the base assembly includes:

[0026] The brake disengages from the base assembly in a direction opposite to the insertion direction of the reset unit, causing the spring-loaded part to move along the first groove wall and disengage from the limiting groove. Under the action of the first groove wall, the insertion part moves relative to the first brake pad and the second brake pad in the insertion direction of the insertion part. The first groove wall is the side of the limiting groove away from the pad limiting block.

[0027] In a second aspect, the present invention also provides a brake assembly system applicable to any of the brake assembly methods in the first aspect, the brake assembly system comprising:

[0033] Optionally, the driving assembly includes a first driving unit and a second driving unit disposed on the base assembly; the first driving unit and the second driving unit are respectively disposed on both sides of the sheet limiting block and are spaced apart from the sheet limiting block;

[0034] The assembly state includes: the second drive unit drives the second brake pad to abut against one side of the pad limiting block, and the first drive unit drives the first brake pad to abut against the other side of the pad limiting block.

[0035] Optionally, the assembly state also includes: the pre-installed end of the caliper is assembled to the pre-installed end of the bracket;

[0036] The contact area between the second brake pad and the second drive unit is the output area. The minimum distance between the output area and the pre-installed end of the second brake pad near the bracket is greater than the minimum distance between the output area and the pre-installed end of the second brake pad away from the bracket.

[0037] Optionally, the assembly state includes: the second drive unit drives the second brake pad to move along the direction close to the pad limiting block, and the moving distance of the end of the second brake pad close to the pre-installed end of the bracket is greater than the moving distance of the end of the second brake pad away from the pre-installed end of the bracket.

[0057] The brake 40 requires multiple components, including the caliper 44, bracket 41, first brake pad 42, second brake pad 43, and reset unit 45, to work together to complete the braking function during operation. However, these parts have different material properties, manufacturing processes, and service lives—brake pads are consumable parts that need to be replaced periodically, while the caliper 44 and bracket 41 are metal structural components that can be used for a long time, and the reset unit needs to have specific elastic properties—therefore, they cannot be integrally molded and must be manufactured separately and then assembled into an assembly. For the brake 40 of this application, if... Figure 4 , Figure 6 , Figure 7As shown, the assembly consists of a bracket 41, a caliper 44, a first brake pad 42, a second brake pad 43, and a reset unit 45. During assembly, the first brake pad 42 and the second brake pad 43 are slidably mounted into the grooves on both sides of the bracket 41 for holding the brake pads. Then, the two ends of the reset unit 45 are inserted into the insertion holes in the first brake pad 42 and the second brake pad 43, respectively. Finally, the caliper 44 is pressed onto the bracket 41, completing the assembly of the caliper 44 and the bracket 41. When inserting the reset unit 45 into the insertion holes of the first brake pad 42 and the second brake pad 43, the reset unit 45 has a large elastic force. Manual assembly requires considerable force to compress the reset unit 45 to ensure smooth insertion. Furthermore, after the reset unit 45 is inserted, removing the applied force easily causes the reset unit 45 to release its compressed elastic potential energy, resulting in it detaching from the insertion hole. This makes assembly very difficult and time-consuming.

[0058] Example 1:

[0059] In this embodiment, as Figure 1 As shown, in order to solve the above problems, this application discloses a brake 40 assembly method, including steps S10, S20, S30, S40 and S50.

[0060] In step S10, based on the positioning and clamping of the bracket 41 on the base assembly 10, the first brake pad 42 and the second brake pad 43 are inserted into the bracket 41. The first brake pad 42 and the second brake pad 43 are not installed in one step, but are only inserted into the bracket 41 from the area between the drive assembly 20 and the limiting assembly 30 to complete the preliminary pre-installation, which reduces the difficulty of operation. When the brake pad is first inserted, it does not need to be precisely aligned with the final working position. Only the preliminary pre-installation needs to be completed, which reduces the positioning accuracy requirements of a single operation.

[0061] Specifically, the positioning clamping bracket 41 abuts against the base assembly 10. One side of the bracket 41 is located between one side of the limiting assembly 30 and the driving assembly 20, and the other side of the bracket 41 is located between the other side of the limiting assembly 30 and the driving assembly 20. That is, the bracket 41 is fitted on the limiting assembly 30 and locked on the base assembly 10.

[0062] Furthermore, such as Figure 3 As shown, the base assembly 10 includes a base body 11 and a fixing unit 12; the fixing unit 12, the limiting component 30 and the driving component 20 are all disposed on the base body 11, and the fixing unit 12 fixes the bracket 41 to the base body 11.

[0063] Furthermore, such as Figure 7As shown, the fixing unit 12 includes a fixing member 121 and a fixing part 122. The fixing part 122 is fixed on the base 11, and the fixing member 121 is installed on the fixing part 122. The fixing member 121 passes through the locking hole on the bracket 41 to lock and fix the bracket 41.

[0064] Step S20: Based on the first brake pad 42 and the second brake pad 43 being inserted into the bracket 41, the reset unit 45 is pre-installed.

[0065] Specifically, the pre-installed reset unit 45 refers to a reset unit 45 whose pair of insertion portions 451 are respectively inserted into the first brake pad 42 and the second brake pad 43, and the spring-loaded portion 453 of the reset unit 45 abuts against the limiting groove 33; since the first brake pad 42 and the second brake pad 43 are not directly installed in place, the gap between the first brake pad 42 and the second brake pad 43 is relatively large, so the reset unit 45 can be inserted into the first brake pad 42 and the second brake pad 43 without applying a large force to compress it; the limiting groove 33 provides a space for the spring-loaded portion 453 and prevents the reset unit 45 from being dislodged from the first brake pad 42 and the second brake pad 43 by subsequent forces; Figure 8 , Figure 10 and Figure 11 As shown, the reset unit 45 includes a pair of plug-in portions 451, a pair of connecting portions 452, and a spring-loaded portion 453; the two ends of the connecting portion 452 are respectively connected to the plug-in portions 451 and the spring-loaded portion 453, and the pair of connecting portions 452 are respectively connected to the two ends of the spring-loaded portion 453; the pair of plug-in portions 451 are respectively inserted into the first brake pad 42 and the second brake pad 43, and the connecting portion 452 is used to connect the plug-in portions 451 and the spring-loaded portion 453; specifically, the reset unit 45 can be a figure-eight spring.

[0066] In step S30, based on the pre-installation of the reset unit 45, the drive assembly 20 drives the first brake pad 42 and the second brake pad 43 to abut against the opposite sides of the pad limiting block 31. As the distance between the first brake pad 42 and the second brake pad 43 gradually decreases, the reset unit 45 is compressed. Due to the presence of the drive assembly 20, the first brake pad 42 and the second brake pad 43 can stably maintain contact with the pad limiting block 31 without being bounced off by the compression force of the reset unit 45. At the same time, the reset unit 45 undergoes compression deformation, specifically: a pair of insertion parts 451 and a pair of connecting parts 452 close together, and the spring-loaded part 453 arches upward. The spring limiting block 32 restricts the spring-loaded part 453 within the limiting groove 33 and applies a force to it along the insertion direction of the reset unit 45, thereby preventing the spring-loaded part 453 from being squeezed out or detached from the limiting groove 33.

[0067] In step S40, the spring-limiting block 32 restricts the spring-rebound part 453 within the limiting groove 33, completing the assembly of the bracket 41 and the caliper 44. After the first brake pad 42, the second brake pad 43, and the reset unit 45 are all assembled, the caliper 44 covers the bracket 41 for assembly, restricting the first brake pad 42, the second brake pad 43, and the reset unit 45 between the bracket 41 and the caliper 44.

[0068] In step S50, based on the completion of the assembly of bracket 41 and caliper 44, brake 40 is detached from base assembly 10. The completion of the assembly of bracket 41 and caliper 44 means that the overall assembly of brake 40 is completed. Brake 40 needs to be removed from base assembly 10 for the next process.

[0069] Further, step S10 may include steps S11 to S12, and the brake assembly method executes steps S11, S12, S20, S30, S40 and S50 in sequence.

[0070] Step S11: Position and clamp the bracket 41 on the base assembly 10, and pre-assemble the pre-assembled end of the bracket 41 with the pre-assembled end of the caliper 44. It should be noted that the caliper 44 and the bracket 41 share two ends that need to be aligned and assembled. For ease of subsequent description, these two ends are defined as the first end and the second end, with the first end defined as the pre-assembled end. First, pre-align and assemble the first end of the bracket 41 and the caliper 44, then align and assemble the second end. Compared to aligning and assembling both ends simultaneously, this method of pre-assembling the first end is simpler, less prone to interference with the brake pads due to space constraints, and improves assembly efficiency.

[0071] In step S12, based on the pre-assembly of the pre-installed end of the bracket 41 and the pre-installed end of the caliper 44, the first brake pad 42 and the second brake pad 43 are inserted into the bracket 41.

[0072] Further, step S30 includes steps S31 to S34, and the brake assembly method sequentially executes steps S11, S12, S20, S31, S32, S33, S34, S40 and S50.

[0073] In step S31, based on the pre-assembly of the reset unit 45, the drive assembly 20 drives the first brake pad 42 to move to the first position and drives the second brake pad 43 to move to the second position. The first position is where the first brake pad 42 has moved a certain distance but has not yet abutted against the pad limiting block 31; the second position is where the second brake pad 43 has moved a certain distance but has not yet abutted against the pad limiting block 31. In other words, the drive assembly 20 does not directly push the first brake pad 42 and the second brake pad 43 to the final abutting position all at once, but rather uses a multi-stage, gradual driving method. This design avoids the reset unit 45 being forced out of the limiting groove 33 due to excessive compressive force instantaneously, providing a buffer adaptation process for the reset unit 45, thereby ensuring the stability and reliability of the assembly.

[0074] In step S32, based on the first brake pad 42 moving to the first position and the second brake pad 43 moving to the second position, the second drive unit 22 drives the second brake pad 43 to abut against one side of the pad limiting block 31; as Figure 6 As shown, the drive assembly 20 includes a first drive unit 21 and a second drive unit 22; the contact area between the second brake pad 43 and the second drive unit 22 is defined as the output area. The minimum distance between the output area and the end of the second brake pad 43 near the pre-installed end of the bracket 41 is greater than the minimum distance between the output area and the end of the second brake pad 43 away from the pre-installed end of the bracket 41. That is, the second drive unit 22 is eccentrically positioned relative to the second brake pad 43. Generally, in order to apply a more uniform force to the brake pad, the output end of the drive unit is aligned with the center of the brake pad, so that the minimum distance from the contact area to both ends of the brake pad is equal. However, since the first end of the caliper 44 is pre-installed in this solution, the caliper 44 needs to be flipped around the first end and pressed onto the bracket 41. If a conventional centered setting is used, the caliper 44 will interfere with the output end of the second drive unit 22 during the flipping process. Therefore, the above-mentioned eccentric setting is adopted to effectively avoid interference.

[0075] Because the second drive unit 22 is eccentrically positioned, the driving force applied to both ends of the second brake pad 43 is uneven, causing the end of the second brake pad 43 near the pre-installed end to tend to warp outward.

[0076] To solve this problem, the movement distance of the second brake pad 43 driven by the second drive unit 22 near the pre-installed end of the bracket 41 is greater than the movement distance of the second brake pad 43 away from the pre-installed end of the bracket 41; that is, the side of the contact surface between the pad limiting block 31 and the second brake pad 43 near the pre-installed end is gradually thinned, and this contact surface is set as a slope. In this way, when the second drive unit 22 drives the second brake pad 43 to abut against the pad limiting block 31, the end of the second brake pad 43 near the pre-installed end is guided by the slope and will not warp outward, ensuring a flat contact of the brake pad.

[0077] In step S33, the second driving unit 22 drives the second brake pad 43 to abut against one side of the pad limiting block 31, and the first driving unit 21 drives the first brake pad 42 to abut against the other side of the pad limiting block 31. Since the forces on both ends of the second brake pad 43 are unbalanced, the second brake pad 43 is driven into position first, and then the first brake pad 42 is driven into position. This avoids mutual interference caused by the force difference when the two brake pads move at the same time, and ensures that the second brake pad 43 completes the attitude adjustment independently under the eccentric drive first, thereby providing a stable reference for the subsequent abutment of the first brake pad 42 and improving the smoothness and reliability of the overall assembly.

[0078] In step S34, the first driving unit 21 drives the first brake pad 42 to abut against the other side of the pad limiting block 31, while simultaneously driving the reset unit 45 to deform, and the spring limiting block 32 restricts the springback part 453 within the limiting groove 33.

[0079] Further, step S33 includes steps S331 and S332, and the brake assembly method sequentially executes steps S11, S12, S20, S31, S32, S331, S332, S34, S40 and S50.

[0080] Step S331: Based on the second drive unit 22 driving the second brake pad 43 to abut against one side of the pad limiting block 31, the external drive module 212 of the first drive unit 21 drives the first brake pad 42 to abut against the other side of the pad limiting block 31 on the side away from the pre-installed end of the bracket 41; as Figure 7 As shown, the first drive unit 21 includes an inner drive module 211 and an outer drive module 212, with the inner drive module 211 located near the first end and the outer drive module 212 located near the second end.

[0081] In step S332, the external drive module 212 drives the first brake pad 42 to abut against the other side of the pad limiting block 31, and the internal drive module 211 of the first drive unit 21 drives the side of the first brake pad 42 near the pre-installed end of the bracket 41 to abut against the other side of the pad limiting block 31. Since the second brake pad 43 has already abutted against the inclined structure pad limiting block 31, its posture is determined as follows: the side near the thin end of the inclined surface is relatively rearward, and the side near the thick end of the inclined surface is relatively forward. The reset unit 45 is inserted into the first brake pad 42 and the second brake pad 43. To prevent the reset unit 45 from being twisted and extruded due to localized instantaneous overload and to ensure the first brake pad 42 is smoothly positioned, the outer drive module 212, which is closer to the thicker end of the inclined surface, should be driven first. This causes the side of the first brake pad 42 near the second end to first abut against the pad limiting block 31, and the reset unit 45 near the second end is compressed uniformly to establish a stable fulcrum. Then, the inner drive module 211, which is closer to the thinner end of the inclined surface, should be driven to gradually close the side of the first brake pad 42 near the first end into place, and the reset unit 45 is uniformly compressed as a whole. If the inner drive module 211 is driven first, the side of the reset unit 45 near the first end will be subjected to instantaneous extreme pressure, generating a torsional torque, which may cause the reset unit 45 to be extruded from the limiting groove 33, and the first brake pad 42 to lose its posture.

[0082] Further, step S40 includes steps S41 and S42, and the brake assembly method sequentially executes steps S11, S12, S20, S30, S41, S42 and S50.

[0083] In step S41, based on the spring limiting block 32 restricting the springback part 453 within the limiting groove 33, the caliper 44 rotates around the pre-installed end of the caliper 44 and presses onto the bracket 41.

[0084] Step S42: Based on the caliper 44 pressing onto the bracket 41, the end of the caliper 44 to be assembled and the end of the bracket 41 to be assembled are assembled, thus completing the assembly of the bracket 41 and the caliper 44; since the first end of the caliper 44 and the bracket 41 has been pre-assembled, the caliper 44 rotates and presses onto the bracket 41 with the first end as the rotation center, and the remaining second end is assembled.

[0085] Furthermore, step S50 includes step S51, which is an optimization of step S50. The brake assembly method executes steps S10, S20, S30, S40 and S51 in sequence.

[0086] In step S51, based on the completion of the assembly of the bracket 41 and the caliper 44, the brake 40 disengages from the base assembly 10 in a direction opposite to the insertion direction of the reset unit 45, causing the spring portion 453 to move along the first groove wall and disengage from the limiting groove 33. Under the action of the first groove wall, the insertion portion 451 moves relative to the first brake pad 42 and the second brake pad 43 in the insertion direction of the insertion portion 451. The first groove wall is the side of the limiting groove 33 away from the pad limiting block 31, formed by the bottom of the limiting groove 33 extending away from the pad limiting block 31. One end of the first groove wall is connected to the bottom of the limiting groove 33, and the other end is connected to the spring limiting block 32, with the other end closer to the second end of the bracket 41 than the first end. Therefore, when the spring portion 453 moves relative to the first groove wall, the first groove wall applies a reaction force to the spring portion 453, thereby driving the reset unit 45 to insert more deeply into the first brake pad 42 and the second brake pad 43. Specifically, the first groove wall can adopt an arc surface or a sloped surface structure, preferably a sloped surface, so that the springback part 453 can smoothly disengage from the limiting groove 33.

[0087] Example 2:

[0088] In this embodiment, as Figure 2 and Figure 5 As shown, a brake 40 assembly system is disclosed, which is applied to any of the brake 40 assembly methods in Embodiment 1. The brake 40 assembly system includes: a base assembly 10, which provides overall support and positioning.

[0089] like Figure 3 As shown, the limiting component 30 includes a sheet limiting block 31, a spring limiting block 32, and a limiting groove 33; the sheet limiting block 31 is disposed on the base component 10, the spring limiting block 32 is fixed to the end of the sheet limiting block 31 away from the base component 10, and the limiting groove 33 is formed on the spring limiting block 32.

[0090] The drive component 20 is disposed on the base component 10;

[0091] like Figure 4 and Figure 7 As shown, the brake 40 includes a bracket 41, a caliper 44, a first brake pad 42, a second brake pad 43, and a reset unit 45; as Figure 8 , Figure 10 and Figure 11 As shown, the reset unit 45 includes a pair of plug-in portions 451, a pair of connecting portions 452, and a spring-loaded portion 453; the two ends of the connecting portion 452 are respectively connected to the plug-in portion 451 and the spring-loaded portion 453, and the pair of connecting portions 452 are respectively connected to the two ends of the spring-loaded portion 453; specifically, the reset unit 45 is a figure-eight spring.

[0092] The assembly state of the brake 40 includes: a bracket 41 is mounted on the base assembly 10 and sleeved on the pad limiting block 31, and is fixed on the base assembly 10 to ensure assembly stability; the first brake pad 42 and the second brake pad 43 are inserted into the bracket 41, inserted into the bracket 41 from the area between the drive assembly 20 and the pad limiting block 31; a pair of insertion parts 451 are respectively inserted into the first brake pad 42 and the second brake pad 43, and the spring part 453 abuts against the limiting groove 33 to position the spring part 453; the drive assembly 20... The first brake pad 42 and the second brake pad 43 are driven to abut against the opposite sides of the pad limiting block 31, thereby reducing the gap between the first brake pad 42 and the second brake pad 43. This causes the reset unit 45, which is inserted into the first brake pad 42 and the second brake pad 43, to be compressed. At the same time, the reset unit 45 is deformed, specifically, a pair of insertion parts 451 and a pair of connecting parts 452 close together, the spring part 453 arches up, and the spring limiting block 32 restricts the spring part 453 in the limiting groove 33 to prevent the spring part 453 from being squeezed out of the limiting groove 33.

[0093] Furthermore, such as Figure 3 As shown, the drive assembly 20 includes a first drive unit 21 and a second drive unit 22 disposed on the base assembly 10; the first drive unit 21 and the second drive unit 22 are respectively disposed on both sides of the pad limiting block 31 and spaced apart from the pad limiting block 31; the gap between the first drive unit 21 and the pad limiting block 31 provides a receiving space for one side of the bracket 41 and the first brake pad 42, and the gap between the second drive unit 22 and the pad limiting block 31 provides a receiving space for the other side of the bracket 41 and the second brake pad 43; the assembly state includes: the second drive unit 22 drives the second brake pad 43 to abut against one side of the pad limiting block 31, and the first drive unit 21 drives the first brake pad 42 to abut against the other side of the pad limiting block 31; that is, the first drive unit 21 and the second drive unit 22 drive the corresponding brake pads independently, and the two do not interfere with each other.

[0094] Furthermore, such as Figure 7 As shown, the second drive unit 22 includes a second mounting part 221 and a second drive part 222. The second mounting part 221 is fixed on the base 11, and the second drive part 222 is disposed on the second mounting part 221 and can extend and retract relative to the second mounting part 221. The second drive part 222 is used to drive the second brake pad 43 to abut against the pad limiting block 31.

[0095] Furthermore, the assembly state also includes: the pre-installed end of the caliper 44 is assembled to the pre-installed end of the bracket 41; such as Figure 6As shown, the contact area between the second brake pad 43 and the second drive unit 22 is the output area. The minimum distance between the output area and the end of the second brake pad 43 near the pre-installed end of the bracket 41 is greater than the minimum distance between the output area and the end of the second brake pad 43 away from the pre-installed end of the bracket 41. When the caliper 44 is pre-installed at one end, the output end of the second drive unit 22 is eccentrically set to prevent interference between the second drive unit 22 and the caliper 44.

[0096] Further, the assembly state includes: the second drive unit 22 drives the second brake pad 43 to move along the direction close to the pad limiting block 31, and the moving distance of the end of the second brake pad 43 near the pre-installed end of the bracket 41 is greater than the moving distance of the end of the second brake pad 43 away from the pre-installed end of the bracket 41; specifically, the contact surface between the pad limiting block 31 and the second brake pad 43 is defined as surface A, and the plane where the output end of the second drive unit 22 is located is defined as surface B. The distance from the side of surface A near the pre-installed end to surface B is greater than the distance from the side of surface A away from the pre-installed end to surface B. When the output end of the second drive unit 22 is eccentrically set, the driving force applied to both ends of the second brake pad 43 is unbalanced, which will cause the side of the second brake pad 43 near the pre-installed end to tend to lift up. By setting surface A to the above-mentioned unequal spacing structure (i.e., the side near the pre-installed end is relatively far away from surface B), the lifting up of the second brake pad 43 can be effectively prevented. Preferably, the contact surface between the pad limiting block 31 and the second brake pad 43 is set as an inclined surface.

[0097] Furthermore, such as Figure 3 , Figure 8 and Figure 9 As shown, the bottom of the limiting groove 33 extends away from the plate limiting block 31 to form a first groove wall; one end of the first groove wall is connected to the bottom of the limiting groove 33, and the other end of the first groove wall is located between the bottom of the limiting groove 33 and the insertion part 451, where the projection line on the spring limiting plate limiting block 32 is located; when the spring part 453 moves relative to the first groove wall, the first groove wall applies a reaction force to the spring part 453, thereby causing the reset unit 45 to be inserted deeper into the first brake pad 42 and the second brake pad 43. Specifically, the first groove wall can be an arc surface or a slope, preferably a slope, so that the spring part 453 can smoothly disengage from the limiting groove 33. In another embodiment, the limiting groove 33 is a V-shaped groove, and the side of the groove wall near the plate limiting block 31 is also set as a slope to fit the connecting part 452 in the reset unit 45.

[0098] The assembly state also includes: the brake 40 disengaging from the base assembly 10 in a direction opposite to the insertion direction of the reset unit 45, causing the spring-loaded part 453 to move along the first groove wall and disengage from the limiting groove 33, and the insertion part 451 moving relative to the first brake pad 42 and the second brake pad 43 in the insertion direction of the insertion part 451 under the action of the first groove wall.

[0099] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
