Description

Technical Field

[0001] The present invention relates to the technical field of vehicle braking, and in particular to a wear compensation mechanism of a braking device, a braking device and a vehicle. Background Art

[0002] Braking systems are devices that stop or slow down a moving vehicle, other transportation, or machinery, or hold a stopped vehicle in place. Because the structure and performance of braking systems are directly related to the safety of vehicles and personnel, they are considered critical safety features and receive widespread attention.

[0003] Conventional braking systems typically consist of a brake and a brake rim. Under normal circumstances, there's a gap between the brake and the rim. When the vehicle needs to brake, the brake actuator rotates, causing the brake to move, resulting in friction between the brake and the rim, generating braking force. Over time, the brake or rim wears, creating a gap.

[0004] However, the existing brake transmission mechanism has a limited rotation angle. After actuation, the brake transmission mechanism returns to its original angle, causing it to rotate within a specified range. The effective braking eccentricity is fixed. For worn brakes and brake rims, the rotation angle cannot be further increased, preventing the brakes from expanding further to compensate for the brake clearance. As a result, the worn brake device cannot effectively brake the vehicle, posing a safety hazard. Furthermore, after a period of use, the brake cable may become loose, which can affect the braking travel and thus the braking effect.

[0005] Furthermore, when a vehicle's brake system wears out, existing technology relies on manual replacement, requiring complex disassembly and assembly of parts and requiring frequent replacement. When shared bikes, electric bikes, and food delivery vehicles experience severe brake wear, the vehicle must be located, the brake system maintained, and then released to the market, resulting in prohibitively high labor costs. Summary of the Invention

At the same time, since an initial deflection angle can be provided for the brake transmission mechanism, when the brake line has a slack problem, the braking stroke of the brake line can be compensated, so that the brake line only needs a shorter stroke to brake the vehicle.

[0072] The present invention provides a wear compensation mechanism for a brake device, comprising an adjustment mechanism, a slide, and a slide slot. The adjustment mechanism is connected to the brake transmission mechanism of the brake device and can drive the brake transmission mechanism to rotate in a braking direction or a reset direction. The slide is provided in correspondence with the adjustment mechanism to limit the swing range of the adjustment mechanism. The slide is mounted in the slide slot, which limits the slide's movement in the reset direction. The adjustment mechanism can drive the slide to move in the braking direction within the slide slot. The wear compensation mechanism of the brake device can compensate for brake clearance, ensure braking effectiveness, and reduce safety hazards.

[0073] Example 1

[0074] Please refer to Figure 1 and Figure 2. This embodiment provides a wear compensation mechanism 10 of a braking device, which is used to compensate for the brake clearance after the brake and / or brake rim of the braking device are worn to produce a brake clearance, to ensure that the brake and the brake rim can fit together and to ensure the braking effect. Specifically, the wear compensation mechanism 10 of the braking device is used to perform angle compensation on the brake transmission mechanism that drives the brake to expand outward. When the braking device is worn, the wear compensation mechanism 10 of the braking device can compensate for an initial deflection angle for the brake transmission mechanism, thereby allowing the brake transmission mechanism to rotate to a larger angle, so that the brake can further expand outward to a larger distance to compensate for the brake clearance.

[0075] The wear compensation mechanism 10 of the braking device includes an adjustment mechanism 11, a slide 12 and a slide groove 13. The adjustment mechanism 11 is connected to the brake transmission mechanism 20 of the braking device and can drive the brake transmission mechanism 20 to rotate along the braking direction or the reset direction. The braking direction refers to when the brake transmission mechanism 20 rotates along this direction, it will cause the brake in the braking device to expand outward. The reset direction is the direction opposite to the braking direction. Specifically, when the brake transmission mechanism 20 rotates along this direction, it will cause the brake in the braking device to retract inward. In this embodiment, the braking direction is along Figure 5 The reset direction is clockwise as shown. Figure 5 Shown counterclockwise.

[0076] The slide 12 is positioned corresponding to the adjustment mechanism 11 to limit the swing range of the adjustment mechanism 11. Specifically, the slide 12 is positioned so that at least a portion of the area overlaps with the adjustment mechanism 11, and the slide 12 is partially inserted into the adjustment mechanism 11, or vice versa. The slide 12 thus limits and blocks the adjustment mechanism 11, ensuring that the relative positions of the adjustment mechanism 11 and the slide 12 remain within a certain range. The adjustment mechanism 11 can only swing within a certain range within the slide 12, or the slide 12 can only move within a certain range within the adjustment mechanism 11.

[0077] The slide 12 is installed in the slide groove 13. The slide groove 13 is used to limit the movement of the slide 12 in the reset direction, and the adjustment mechanism 11 can drive the slide 12 to move in the braking direction in the slide groove 13. Here, moving in the reset direction means moving along the reset direction or moving toward the reset direction, and moving in the braking direction means moving along the braking direction or moving toward the braking direction.

[0078] Therefore, when the brake device is functioning normally, external force is applied to cause the adjustment mechanism 11 to swing about the brake transmission mechanism 20, thereby driving the brake transmission mechanism 20 to rotate. The brake transmission mechanism 20 then causes the brake in the brake device to expand outward, causing the brake to contact and rub against the brake rim, thereby achieving braking. At this time, the swing amplitude of the adjustment mechanism 11 is limited within the slide 12, and the adjustment mechanism 11 does not contact the slide 12, or the adjustment mechanism 11 only slightly contacts the slide 12, preventing the slide 12 from moving within the slide slot 13.

[0079] When the brake or brake rim in the braking device wears out and a brake gap is formed, when force is applied, since the brake and the brake rim are not in contact, no resistance is generated, which increases the movement stroke of the adjustment mechanism 11 and allows the adjustment mechanism 11 to swing with a greater amplitude in the braking direction. This causes the adjustment mechanism 11 to contact the slide 12 and generate a driving force on the slide 12, prompting the slide 12 to move in the braking direction within the slide groove 13. When the adjustment mechanism 11 is reset, the slide 12 is restricted by the slide groove 13 and cannot return to its initial position in the reset direction. The slide 12 blocks the adjustment mechanism 11, preventing the adjustment mechanism 11 from returning to its initial position. This in turn prevents the brake transmission mechanism 20 from returning to its original angle, resulting in an initial deflection angle in the initial state. Therefore, during the next braking action, since the brake transmission mechanism 20 has a deflection angle in its initial state, applying force to the adjustment mechanism 11 can rotate the brake transmission mechanism 20 to a larger angle, compensating for the brake clearance, ensuring braking effectiveness, and reducing safety hazards. Furthermore, since an initial deflection angle can be provided for the brake transmission mechanism 20, even when the brake cable is slack, the braking travel of the brake cable can be compensated, allowing the brake cable to brake the vehicle with a shorter travel. For example, under normal circumstances, the brake cable requires five travels to achieve braking, but when the brake cable is slack, it requires six travels to achieve braking. The wear compensation mechanism 10 of the braking device provided in this embodiment can compensate for the initial deflection angle of the brake transmission mechanism 20. This reduces the required rotation angle of the brake transmission mechanism 20 even after the brake cable is slack, thereby reducing the travel required for the brake cable to achieve braking. Even after the brake cable is slack, only five travels of the brake cable are still required to achieve braking. That is, the initial deflection angle of the brake transmission mechanism 20 is compensated, and the brake line stroke can also be compensated to ensure the braking effect of the vehicle.

[0080] That is to say, the slide groove 13 is a one-way slide groove. After the slide 12 is subjected to force, it can only move toward the braking direction in the slide groove 13, and cannot be reset toward the reset direction. Then, the slide 12 blocks the adjustment mechanism 11, prompting the brake transmission mechanism 20 to obtain an initial deflection angle to achieve compensation for the wear amount.

[0081] In this embodiment, the brake transmission mechanism 20 is specifically a camshaft. The chute 13 is arc-shaped, thereby better matching the deflection of the adjustment mechanism 11. Of course, in other embodiments, the chute 13 can also have other shapes, or even a straight line. In other words, the chute 13 only needs to restrict the slide 12 to move in one direction, thereby achieving deflection angle compensation for the brake transmission mechanism 20.

[0082] Preferably, the slide 13 includes a slot body 131 and a latching slot 132. The latching slots 132 are disposed within the slot body 131, with multiple latching slots 132 spaced sequentially in the braking direction. The slide 12 is at least partially retained within one of the latching slots 132, and the adjustment mechanism 11 is capable of driving the slide 12 to slide into another adjacent latching slot 132 in the braking direction. In other words, the latching slots 132 serve to block and limit the slide 12, preventing it from moving in the reset direction. It will be appreciated that, in this embodiment, by providing multiple, sequentially spaced latching slots 132, wear can be gradually compensated until the slide 12 slides into the last latching slot 132. This gradual compensation approach allows for more accurate and effective wear compensation, while also preventing excessive compensation from causing overly sensitive braking that could affect normal vehicle operation. It should be noted that, in this embodiment, the latching slots 132 are disposed within the slot body 131. Of course, in other embodiments, the latching slot 132 may be provided outside the slot body 131, that is, it is sufficient to provide the slot body 131 to guide the slide 12, and limit the slide 12 via the latching slot 132. In this embodiment, however, the latching slot 132 is provided in the slot body 131, which facilitates the arrangement of the slide 12, simplifies the structure of the slide 12, and facilitates manufacturing.

[0083] Preferably, the engaging slot 132 includes a bottom surface 1321, a first side surface 1322, and a second side surface 1323. The first side surface 1322 is connected to one side of the bottom surface 1321, and the second side surface 1323 is connected to the other side of the bottom surface 1321. The first side surface 1322 is located on the side closer to the braking direction and is an inclined surface. That is, the first side surface 1322 is inclined relative to the bottom surface 1321. Therefore, when the slide 12 is subjected to a force in the braking direction, the first side surface 1322 can guide the portion of the slide 12 within the engaging slot 132, allowing the portion of the slide 12 within the engaging slot 132 to more easily enter the next adjacent engaging slot 132. The inclined surface of the first side surface 1322 facilitates movement of the slide 12 within the slide slot 13, reduces the force required to drive the slide 12, and thus facilitates compensation for wear.

[0084] Preferably, the slide 12 includes a base 121, a limiting post 122, and an elastic member 123. The base 121 is mounted in the slot body 131, the limiting post 122 is disposed on the base 121, and the elastic member 123 is mounted on the base 121 and partially engaged in the engaging slot 132. Two limiting posts 122 are provided, and the two limiting posts 122 are spaced apart to form a limiting space 124. The adjustment mechanism 11 is at least partially located in the limiting space 124. That is, when the slide 12 is subjected to force, the elastic member 123 is deformed, causing the elastic member 123 to slide out of the engaging slot 132 and slide into another adjacent engaging slot 132 in the braking direction. The two limiting posts 122 limit the adjustment mechanism 11 in the limiting space 124. When the swing amplitude of the adjustment mechanism 11 increases, it will be blocked by the limiting posts 122, thereby limiting the position of the adjustment mechanism 11, or the adjustment mechanism 11 drives the slide 12 to move. It should be noted that in this embodiment, by providing the limiting posts 122 on both sides, the adjustment mechanism 11 is partially inserted into the limiting space 124, thereby limiting the swing position of the adjustment mechanism 11 by the slide 12. Of course, in other embodiments, the limiting space 124 can also be provided on the adjustment mechanism 11, specifically, a corresponding slide groove can be provided on the adjustment mechanism 11, and correspondingly, a limiting post can be provided on the slide 12 to be inserted into the slide groove, so that after the limiting post slides a certain distance in the slide groove, it will be blocked by the side walls on both sides of the slide groove, thereby limiting the swing amplitude of the adjustment mechanism 11. In other words, it is only necessary to provide a corresponding limiting structure between the adjustment mechanism 11 and the slide 12 to limit the swing range of the adjustment mechanism 11 relative to the slide 12, thereby driving the slide 12 in the braking direction and limiting the adjustment mechanism 11 from resetting in the resetting direction through the contact between the adjustment mechanism 11 and the slide 12. More preferably, the elastic member 123 is a metal spring, which is less susceptible to damage. More preferably, one end of the adjustment mechanism 11 is inserted into the limiting space 124 and extends out of the limiting space 124, so that the adjustment mechanism 11 can block the slide 12 and prevent the slide 12 from accidentally falling out of the chute 13.

[0085] Preferably, the base 121 includes a main body 1211 and a mounting slot 1212 defined in the main body 1211. The elastic member 123 includes a main body 1231 mounted in the mounting slot 1212, and an elastic member 1232 having one end connected to the main body 1231 and the other end engaged in the engaging slot 132. By securing the main body 1231 in the mounting slot 1212, the stability of the installation is ensured, preventing the elastic member 123 from accidentally falling out.

[0086] Preferably, the slot body 131 is provided with the slot 132 on both sides, and each slot 132 is provided with a corresponding elastic portion 1232. That is, the slot 132 is provided on both side walls of the slot body 131, and at least two elastic portions 1232 are provided, each corresponding to the slot 132 on one side. By providing the slots 132 on both sides and each elastic portion 1232 on each side, the slide 12 is subjected to more balanced force when it is secured in the slide 13, preventing accidental ejection or disengagement due to unidirectional force, and effectively ensuring stability.

[0087] Preferably, the seat body 121 further includes an escape groove 1213, which is recessed from the side of the main body 1211 close to the locking groove 132 toward a direction away from the locking groove 132. The escape groove 1213 is provided corresponding to the elastic portion 1232. Therefore, when the elastic portion 1232 is forced to bend inward, the escape groove 1213 can provide a good deformation space for the elastic portion 1232, thereby making the movement of the slide seat 12 toward the braking direction more labor-saving and convenient.

[0088] Example 2

[0089] Please refer to 1 to Figure 11 . This embodiment provides a braking device 100, which includes a housing 30, a brake rim 40, a brake 50, a brake transmission mechanism 20, a wear compensation mechanism of the braking device and a driving mechanism 60. The brake rim 40 is installed on the wheel of the vehicle, and the brake 50 is movably installed on the housing 30 and is arranged corresponding to the brake rim 40. Specifically, the brake 50 is arranged in the brake rim 40, and the brake transmission mechanism 20 is movably installed on the housing 30 and is arranged corresponding to the brake 50 to drive the brake 50 to fit the brake rim 40. The wear compensation mechanism of the braking device adopts the wear compensation mechanism 10 of the braking device described in Example 1. The driving mechanism 60 is connected to the adjusting mechanism 11 to drive the adjusting mechanism 11 to swing. The brake 50 can specifically be a drum brake, an expansion brake, a follow-up brake, etc.

[0090] Specifically, the brake 50 includes two opposing brake shoes 51. The brake 50 and the brake rim 40 are located on one side of the housing 30, while the brake device's wear compensation mechanism 10 and the drive mechanism 60 are mounted on the other side of the housing 30. The brake transmission mechanism 20 is movably mounted on the housing 30 and inserted between the two brake shoes 51. The movably mounted brake transmission mechanism 20 on the housing 30 means that the brake transmission mechanism 20 can rotate on the housing 30 when subjected to force. Under normal circumstances, the outer edges of the two brake shoes 51 are spaced apart from the brake rim 40. When braking is required, the drive mechanism 60 applies force to the adjustment mechanism 11, causing the adjustment mechanism 11 to rotate the brake transmission mechanism 20. The brake transmission mechanism 20 then squeezes the two brake shoes 51 outward, causing them to contact and rub against the brake rim 40, achieving a braking effect. When the brake shoe 51 and / or the brake rim 40 are worn, the initial deflection angle of the brake transmission mechanism 20 can also be compensated by the wear compensation mechanism 10 of the braking device, thereby compensating for the wear of the brake shoe 51 and / or the brake rim 40 by providing the brake transmission mechanism 20 with an initial deflection angle.

[0091] Preferably, the driving mechanism 60 includes a driving plate 61, a brake line 62 and an adaptive adjustment mechanism 63, the driving plate 61 is hinged to the housing 30, and the brake line 62 is connected to the driving plate 61. One end of the adaptive adjustment mechanism 63 is connected to the driving plate 61 and the other end is connected to the adjustment mechanism 11, and the distance between the two ends can be adjusted according to the position of the slide 12. That is, the driving plate 61, the adaptive adjustment mechanism 63, and the adjustment mechanism 11 together constitute a connecting rod structure, and the length of the adaptive adjustment mechanism 63 can be adaptively adjusted according to actual conditions. Among them, the adaptive adjustment mechanism 63 can adjust the distance between the two ends according to the position of the slide 12 specifically: according to the different positions of the slide 12 in the slide groove 13, the spacing between the two hinges of the adaptive adjustment mechanism 63 can be adaptively adjusted, that is, the length of the adaptive adjustment mechanism 63 itself can be adaptively adjusted. Specifically, in this embodiment, after the adjusting mechanism 11 drives the slide 12 to move a certain distance in the braking direction in the slide groove 13, the adaptive adjusting mechanism 63 is subjected to resistance and adaptively adjusted due to the obstruction of the adjusting mechanism 11 by the slide 12 during resetting, so that the distance between the two hinge points of the adaptive adjusting mechanism 63 is shortened, that is, the overall length of the adaptive adjusting mechanism 63 is shortened, so that the adaptive adjusting mechanism 63 will not always apply a large force to the adjusting mechanism 63 in the resetting direction. That is to say, in this embodiment, the adaptive adjustment mechanism 63 is provided to transmit power. After the wear compensation mechanism 10 of the braking device performs wear compensation, the adaptive adjustment mechanism 63 can self-adjust according to the resistance fed back by the adjustment mechanism 11, thereby reducing its overall length, slowing down or eliminating the force applied by the adaptive adjustment mechanism 63 to the adjustment mechanism 11 in the reset direction, and then slowing down or eliminating the force applied by the adjustment mechanism 11 to the slide 12 in the reset direction, effectively avoiding the slide 12 from accidentally sliding back or falling off in the reset direction in the slide groove 13, further ensuring the compensation effect of the wear compensation mechanism 10 of the braking device on the brake transmission mechanism 20, and also ensuring the stability of the wear compensation mechanism 10 of the braking device.

[0092] Preferably, the braking device 100 further includes a reset member 70, which is disposed on the housing 30 and connected to the drive plate 61. The reset member 70 is used to provide a restoring force to the drive plate 61, thereby driving the adjustment mechanism 11 to move in the reset direction. In this embodiment, the reset member 70 is specifically a reset torsion spring. The brake cable 62 is connected to the brake handle of the vehicle. When the vehicle needs to brake, pressing the brake handle pulls the brake cable 62 against the drive plate 61, causing the reset member 70 to deform under the force. After braking is completed and the brake handle is released, the reset member 70 drives the drive plate 61 back to its original position, thereby driving the brake transmission mechanism 20 to return to its original angle. Of course, in other embodiments, the reset member 70 can be disposed in any other desired location and can also adopt any other structure or device that provides a restoring force. In other words, it is sufficient that the reset member 70 provides a restoring force to the braking device 100, so that the braking device 100 can return to its original state after braking. In this embodiment, the reset member 70 is connected to the drive plate 61, so that after the wear compensation mechanism 10 of the braking device performs angle compensation and the adaptive adjustment mechanism 63 performs adaptive adjustment, the reset member 70 will not continue to apply restoring force to the adjustment mechanism 11, thereby ensuring the stability of the wear compensation mechanism 10 of the braking device.

[0093] Preferably, the adaptive adjustment mechanism 63 includes a connecting member 631, an adjusting screw 632, an adjusting nut 633, and a push-rotating member 634. The connecting member 631 has an internal accommodation space 637. The connecting member 631 is hinged to the drive plate 61 or the adjustment mechanism 11. One end of the adjusting screw 632 is hinged to the adjustment mechanism 11 or the drive plate 61, and the other end is at least partially inserted into the accommodation space 637. That is, the connecting member 631 is provided on either the drive plate 61 or the adjustment mechanism 11, and the adjusting screw 632 is provided on the other. In this embodiment, the connecting member 631 is provided on the drive plate 61, and the adjusting screw 632 is provided on the adjustment mechanism 11. The adjusting nut 633 is threadedly connected to the adjusting screw 632 and is located in the accommodation space 637. The connecting member 631 is used to block the adjusting nut 633. The push-rotating member 634 is fixed to the connecting member 631 to drive the adjusting nut 633 to rotate. In a normal state, the push-rotating member 634 does not contact the adjusting nut 633, so the position of the adjusting nut 633 on the adjusting screw 632 does not change. The adjusting nut 633 is blocked by the connecting member 631, so the distance between the connection point of the connecting member 631 and the driving plate 61 and the connection point of the adjusting screw 632 and the adjusting mechanism 11 (the overall length of the adaptive adjusting mechanism 63) does not change. After the wear compensation mechanism 10 of the brake device has performed compensation, the adjustment mechanism 11 is blocked by the slide 12 when returning, while the drive plate 61, driven by the reset member 70, continues to move in the reset direction, thereby driving the connecting member 631 to move toward the side of the adjustment screw 632, causing the other end of the adjustment screw 632 to gradually extend into the connecting member 631. The push-rotating member 634 contacts the adjustment nut 633, driving the adjustment nut 633 to rotate, and the adjustment nut 633 is laterally displaced toward the side closer to the adjustment mechanism 11, shortening the overall length of the adaptive adjustment mechanism 63. Ultimately, the drive plate 61 is driven by the reset member 70 to return to its initial position, and the adaptive adjustment mechanism 63 is also able to adaptively adjust its length to prevent the slide 12 from sliding back or slipping under force.

[0094] Preferably, the adjusting nut 633 is provided with a sliding groove 635 or a protrusion 636 on one side close to the push-rotating member 634, and the push-rotating member 634 is provided with a corresponding protrusion 636 or sliding groove 635. That is, either the adjusting nut 633 or the push-rotating member 634 is provided with the protrusion 636, and the other is provided with the sliding groove 635. In this embodiment, the sliding groove 635 is provided on the adjusting nut 633, and the protrusion 636 is provided on the push-rotating member 634. The sliding groove 635 includes a bottom surface 6351 and a guide slope 6352 connected to the bottom surface 6351. The protrusion 636 is provided corresponding to the guide slope 6352, and the protrusion 636 can slide on the guide slope 6352 to cause the adjusting nut 633 to rotate. That is, when the push-rotating member 634 contacts the adjusting nut 633, the protrusion 636 abuts against the wall of the sliding groove 635, thereby driving the adjusting nut 633 to rotate under the guidance of the guide bevel 6352, thereby causing the adjusting nut 633 to be laterally displaced on the adjusting screw 632 and move toward the side closer to the adjusting mechanism 11. Of course, in other embodiments, any other structure can be used between the adjusting nut 633 and the pushing member 634 to drive the adjusting nut 633 to rotate, and the protrusion 636 can even be directly provided on the inner wall of the connecting member 631, and the sliding groove 635 can also be provided on the side wall of the adjusting nut 633. In this embodiment, the protrusion 636 and the sliding groove 635 are provided at the end, which not only allows the protrusion 636 to be better aligned and adapted with the sliding groove 635, but also reduces the difficulty of processing and facilitates processing.

[0095] Preferably, a plurality of the protrusions 636 are arranged in sequence along the circumferential direction, and each of the protrusions 636 is provided with at least one corresponding sliding groove 635. In this embodiment, there are three protrusions 636, and the number of the sliding grooves 635 is greater than the protrusions 636, and the plurality of sliding grooves 635 are arranged in sequence along the circumferential direction. By providing a plurality of the protrusions 636 to push the adjusting nut 633, the force applied during the driving process is more balanced, so that the adjusting nut 633 does not deflect. It is understandable that in order to ensure that when the protrusion 636 slides into the bottom of the sliding groove 635, it can smoothly enter the next adjacent sliding groove 635 during the next adjustment process, the positions of the guide slopes 6352 corresponding to the three protrusions 636 may be slightly different. Therefore, after one protrusion 636 slides to the bottom, during the next adjustment, the other protrusion 636 can first contact the guide slope 6352, rotating the adjustment nut 633 to a certain position so that the protrusion 636 can slide smoothly into the adjacent sliding slot 635. Furthermore, corresponding inclined or curved surfaces can be provided at corresponding positions on the protrusion 636 to guide the protrusion 636 into the adjacent sliding slot 635. Specifically, the transition surface 638 between two adjacent sliding slots 635 is a sloped surface, wherein the transition surface 638 is the surface of the adjustment nut 633 on the side closest to the push-rotating member 634. Therefore, after the protrusion 636 slides to the bottom of the sliding slot 635, during the next adjustment, the transition surface 638 effectively guides the protrusion 636 into the next adjacent sliding slot 635, thereby ensuring that the push-rotating member 634 can continue to push the adjustment nut 633.

[0096] Specifically, the adjustment mechanism 11 includes a first plate 111 and an extension plate 112 connected to the end of the first plate 111. The extension plate 112 is inserted into the limiting space 124. The first plate 111 is connected to the brake transmission mechanism 20 on the side away from the extension plate 112. The adjustment screw 632 is hinged to the middle of the adjustment mechanism 11. The drive plate 61 includes a second plate 611 and a brake cable clamping portion 612 provided on the second plate 611. The brake cable 62 is clamped to the brake cable clamping portion 612. One end of the second plate 611 is hinged to the housing 30, and the connector 631 is hinged to the middle of the second plate 611. The housing 30 includes a housing body 31, a first hinge point 32, a second hinge point 33, and a brake cable fixing seat 34 provided on the housing body 31. In this embodiment, the slide 13 is provided on the housing body 31. The adjustment mechanism 11 is hinged to the first hinge point 32, the drive plate 61 is hinged to the second hinge point 33, and the brake wire fixing seat 34 is used to fix and limit the position of the brake wire 62, thereby effectively ensuring the transmission of driving force by the brake wire 62.

[0097] It is understood that when the brake device 100 provided in this embodiment wears out, it is only necessary to apply force to increase the travel of the brake cable 62, thereby providing a driving force to move the slide 12 within the slide groove 13 to compensate for the wear. Complicated disassembly and assembly are not required; simply pressing the brake handle can adaptively compensate for the wear of the brake device 100, effectively reducing labor costs and maintenance time, eliminating the need to search for the vehicle for maintenance.

[0098] Example 3

[0099] This embodiment provides a vehicle, which includes the braking device 100 described in the second embodiment. Specifically, the vehicle can be an electric power-assisted bicycle. Of course, in other embodiments, the braking device 100 can also be applied to any other desired vehicle.

[0100] Compared with the prior art, the adjustment mechanism in the wear compensation mechanism of the braking device provided by the present invention is connected to the braking transmission mechanism of the braking device and can drive the braking transmission mechanism to rotate in the braking direction or the resetting direction; the slide is arranged corresponding to the adjustment mechanism to limit the swing range of the adjustment mechanism; the slide is installed in the slide groove, and the slide groove is used to limit the movement of the slide toward the resetting direction, and the adjustment mechanism can drive the slide groove to move toward the braking direction in the slide groove. During normal braking operation, the brake drive is realized by applying force to the adjusting mechanism, thereby driving the brake transmission mechanism to rotate; when the brake device is worn, force is applied to the adjusting mechanism, and the movement stroke of the adjusting mechanism increases, so that the adjusting mechanism contacts the slide, thereby driving the slide to move in the slide groove; when the force application ends, the position of the slide as a whole in the slide groove moves, and the slide is restricted by the slide groove and cannot be reset, so that when the adjusting mechanism is reset in the reset direction, it is blocked by the slide and cannot return to the initial position, thereby preventing the brake transmission mechanism from returning to the original angle, so that the brake transmission mechanism obtains a deflection angle in the initial state, thereby achieving compensation for the wear amount; in the next braking action, since the brake transmission mechanism obtains a deflection angle in the initial state, after force is applied to the adjusting mechanism, the brake transmission mechanism can be rotated to a larger angle to achieve compensation for the brake clearance, thereby ensuring the braking effect and reducing safety hazards. At the same time, since an initial deflection angle can be provided for the brake transmission mechanism, the braking stroke can be compensated when there is a slack problem in the brake line, so that the brake line only needs a shorter stroke to brake the vehicle.

[0101] Correspondingly, the brake device provided by the present invention can effectively compensate for the brake clearance after wear by adopting the wear compensation mechanism of the brake device, thereby effectively ensuring the braking effect and reducing safety hazards.

[0102] Correspondingly, the vehicle provided by the present invention can effectively ensure the braking effect and reduce safety hazards by adopting the braking device.

[0103] The above description is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the creative concept of the present invention, but these improvements all fall within the scope of protection of the present invention.
