Description

Technical Field

[0001] This utility model belongs to the field of locks, and more specifically, it relates to a disc brake lock. This utility model also relates to a disc brake lock assembly system. In addition, this utility model also relates to a two-wheeled vehicle. Background Technology

[0002] Disc brake locks are commonly used anti-theft devices on two-wheeled vehicles, especially motorcycles and electric bicycles. They achieve the purpose of theft prevention by inserting a lock pin into the hole or radial gap on the disc brake disc and mechanically preventing the disc brake disc and wheel from rotating.

[0003] Currently, most electric disc brake locks on the market use a motor-driven gear transmission mechanism to extend the locking pin for locking or retracting it for unlocking. However, this design has significant technical flaws. Traditional transmission mechanisms are mostly rigid connections, meaning the motor's rotation is directly and without buffering converted into the linear motion of the locking pin via the gear set. In actual use, when the locking pin fails to reach the predetermined position due to foreign object jamming, installation misalignment, or thermal deformation of the disc brake disc, or when the motor's power output exceeds its design power, causing the motor to continue driving after the locking pin has reached the set position, the transmission system will experience a huge reverse force. This "stalled" phenomenon can easily cause the motor to overload and burn out, gears to break, or permanent deformation of transmission components, leading to the failure of the entire lock.

[0004] Furthermore, even under normal use, there may be slight misalignment between the locking pin and the disc brake disc hole. Rigid impacts not only generate noise and wear, but also reduce the lifespan of the lock in the long run. Additionally, when encountering abnormal resistance, even if the motor reverses, the rigidly disengaged gears and rack may fail to automatically re-engage, resulting in an awkward situation where the lock "can neither lock nor unlock," posing significant safety risks and inconvenience to users.

[0005] Therefore, there is an urgent need in the existing technology for a disc brake lock solution that can effectively overcome the above-mentioned defects. It must have the ability to protect the drive mechanism under overload, and at the same time ensure that the system can automatically resume reliable operation after the abnormality is resolved. Utility Model Content

[0006] The purpose of this utility model is to provide a disc brake lock to solve the technical problems of existing disc brake locks where the motor is easily damaged and the transmission process of the motor is prone to failure.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a disc brake lock, comprising: The lock housing and the drive gear set and rack that mesh and engage within the lock housing; An elastic clutch assembly is disposed on one side of the rack, comprising a locking pin push block and a rack transmission member that slides with the locking pin push block and is elastically limited thereto. The rack transmission member moves synchronously with the rack to transmit the movement of the rack to the locking pin push block and elastically reciprocates relative to the locking pin push block when the drive gear set rotates under overload, thereby providing clutch protection against the overload rotation of the drive gear set. The locking pin body is located at the power output end of the locking pin push block. As the drive gear set rotates, the locking pin body has a first state of extending out of the lock housing and a second state of retracting into the lock housing.

[0008] Furthermore, the locking pin push block is provided with a connected spring chamber and a slide groove, wherein the radial width of the spring chamber is greater than the radial width of the slide groove, and an elastic element is fitted on the rack transmission component and the elastic element is limited within the spring chamber; When the drive gear set rotates under overload, the rack transmission component slides in the slide groove and is reset by means of the elastic element. The rack transmission component slides and reciprocates in the slide groove, forming a clutch protection for the drive gear set.

[0009] Furthermore, the elastic element is a return spring, and the outer diameter of the return spring is adapted to the radial width of the spring compartment; The bottom of the rack and pinion drive is provided with spring pins for mounting the two ends of the return spring respectively.

[0010] Furthermore, the slide grooves are respectively connected to both ends of the spring housing to provide clutch protection for the drive gear set when the locking pin body is in the first state or the second state.

[0011] Furthermore, the rack and pinion drive component is integrally formed with the rack.

[0012] Furthermore, the drive gear set includes a motor, a worm gear assembled with the output end of the motor, and a gear set meshing with the worm gear; A micro switch is provided on the side of the locking pin push block away from the elastic clutch assembly. The locking pin push block is provided with a touch protrusion corresponding to the micro switch. When the locking pin body is in the unlocking or locking position, the touch protrusion touches or disengages from the micro switch to generate a signal feedback.

[0013] Furthermore, it also includes a plastic encapsulation shell disposed within the lock housing, wherein the drive gear set, the micro switch, and the matching control circuit board are disposed within the plastic encapsulation shell, wherein the final stage gear of the drive gear set, the rack, and the elastic clutch assembly are disposed between the plastic encapsulation shell and the lock housing; A cable outlet box is also provided on the side of the lock housing away from the lock pin body, and the cable outlet box is provided with an S-shaped or bent cable harness groove. An L-shaped reinforcing plate is provided at one end of the lock housing where the locking pin outlet is located. The L-shaped reinforcing plate has a clearance hole, which is adapted to guide the locking pin body.

[0014] Compared with existing technologies, the advantages of the disc brake lock provided by this utility model are as follows: Firstly, this invention utilizes the cooperation of the locking pin body, the elastic clutch assembly, and the drive gear set. The drive gear set meshes with the rack on the elastic clutch assembly. When the drive gear set rotates, the rack drives the locking pin body to move along its own length, causing the locking pin body to move closer to or away from the disc brake disc, thus locking or unlocking. Simultaneously, when the gear rotates and pushes the rack, the elastic clutch assembly undergoes compression or stretching deformation, causing the locking pin to produce axial displacement. When the locking pin reaches its mechanical limit or encounters an obstacle, the elastic clutch assembly allows the rack and gear to maintain elastic contact while disengaging from rigid transmission. This effectively absorbs overload energy and maintains physical contact between the transmission components. Therefore, when the drive gear set rotates more than a preset number of times, the rack and drive gear set disengage but maintain elastic contact, avoiding rigid impact. It can ensure that the locking pin has elastic buffer and overload protection during movement, thereby preventing the drive gear set from being over-rotated due to excessive power output, which could damage the motor. It also ensures that the rack can re-engage when the gear rotates, thus improving the reliability and service life of the disc brake lock and solving the technical problem that traditional disc brake locks are easily damaged due to motor overload or locking pin jamming.

[0015] Furthermore, the return spring is located within the spring housing and is mounted on the rack and pinion drive. When the rack and pinion drive is subjected to force and moves, the return spring is pre-compressed within the rack and pinion drive. Simultaneously, it transmits elastic force to the spring housing through the spring pins at both ends, forming a double elastic support. This transmits the driving force to the rack and pinion drive, thereby driving the locking pin body to move. When the locking pin body is at its maximum stroke, the return spring is compressed to its shortest length, causing the two ends of the rack to press against the drive gear set. This allows the drive gear set to mesh with the rack during rotation, thus facilitating stable meshing between the drive gear set and the rack.

[0016] Furthermore, the nested sliding fit between the locking pin push block and the rack and pinion transmission component allows the sliding block to provide three-dimensional constraint on the movement trajectory of the rack and pinion transmission component. At the same time, the elastic support of the return spring enables the construction of a stable elastic guiding system, thereby ensuring that the elastic deformation is always transmitted in the predetermined direction to eliminate frictional losses caused by lateral load.

[0017] Furthermore, the responsive coordination between the touch-sensitive protrusion and the microswitch utilizes the axial displacement of the locking pin to trigger switch state switching, forming a displacement and electrical signal conversion mechanism. This enables the establishment of a real-time position feedback closed loop, allowing the control system to accurately perceive the actual state of the locking pin, thereby eliminating state misjudgments and achieving the technical effect of obtaining real-time information about the state of the locking pin itself.

[0018] This utility model also proposes a disc brake lock assembly system, which adopts the above-mentioned disc brake lock. The assembly system includes a mounting plate mounted on the wheel hub and a disc brake lock assembly compartment disposed at the front end of the mounting plate. The mounting plate rotates synchronously with the wheel hub and disc brake disc. The outer periphery of the mounting plate has multiple locking grooves evenly arranged around its own axis. The locking grooves are inserted and adapted to the locking pin body. The assembly compartment is an inner groove located on the rear horizontal fork.

[0019] The aforementioned mounting plate rotates synchronously with the wheel hub and disc brake disc, forming a dynamic engagement relationship with the locking pin through circumferentially distributed locking grooves. When the locking pin extends into any locking groove, multi-angle locking is achieved using the inertial torque of the rotating components. This significantly expands the effective locking range, allowing the vehicle to quickly enter the locking state from any stationary position, improving the practicality and response speed of the lock. It eliminates the need for significant wheel hub rotation based on the relative relationship between the locking pin and the wheel hub, thus solving the inconvenience of adjusting wheel angles for single-point locking.

[0020] Another objective of this utility model is to provide a two-wheeled vehicle that uses the disc brake lock or disc brake lock assembly system described above.

[0021] Compared to existing technologies, the two-wheeled vehicle of this invention possesses all the advantages of the aforementioned disc brake locks, which will not be elaborated upon here. Furthermore, this invention integrates the elastic locking mechanism into the vehicle's braking system, forming a mechatronic anti-theft solution. It enables intelligent linkage between the locking action and the status of the two-wheeled vehicle, such as a bicycle, electric bicycle, electric-assisted bicycle, or motorcycle. Moreover, this two-wheeled vehicle is compatible with various power outputs for vehicle locks, improving the compatibility of the two-wheeled vehicle with power supplies and automatic disc brake locks.

Detailed Implementation

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.

[0025] In the description of this utility model, it should be noted that if terms such as "upper", "lower", "inner", "back" or indicating orientation or positional relationship appear, they are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0027] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Please refer to the following: Figures 1 to 3 The disc brake lock provided by this utility model will now be described. The disc brake lock includes a lock housing 6 and a drive gear set 3 and a rack 222 that are meshed and linked within the lock housing 6; an elastic clutch assembly 2 is disposed on one side of the rack 222, which includes a locking pin push block 23 and a rack transmission member 22 that slides with the locking pin push block 23 and is elastically limited, wherein the rack transmission member 22 moves synchronously with the rack 222, is used to transmit the movement of the rack 222 to the locking pin push block 23, and elastically reciprocates relative to the locking pin push block 23 when the drive gear set 3 rotates under overload to form a clutch protection against the overload rotation of the drive gear set 3; the locking pin body 1 is disposed at the power output end of the locking pin push block 23, and as the drive gear set 3 rotates, the locking pin body 1 has a first state of extending out of the lock housing 6 and a second state of retracting into the lock housing 6.

[0029] Compared to existing technologies, this invention, in its specific implementation, utilizes the cooperation of the locking pin body 1, the elastic clutch assembly 2, and the drive gear set 3. The drive gear set 3 meshes with the rack 222 on the elastic clutch assembly 2. When the drive gear set 3 rotates, the rack 222 drives the locking pin body 1 to move along its own length, causing the locking pin body 1 to move closer to or away from the disc brake disc, thus locking or unlocking. Simultaneously, when the gear rotates and pushes the rack 222, the elastic clutch assembly 2 undergoes compression or stretching deformation, causing the locking pin to produce axial displacement. When the locking pin reaches its mechanical limit or encounters an obstacle, the elastic clutch assembly 2 continues to deform, allowing the rack 222 to maintain elastic contact with the gear while disengaging from rigid transmission. This effectively absorbs overload energy and maintains physical contact between transmission components. Thus, when the drive gear set 3 rotates more than a preset number of times, the rack 222 disengages from the drive gear set 3 but maintains elastic contact, avoiding rigid impact. It can ensure that the locking pin has elastic buffer and overload protection during movement, thereby preventing the drive gear set 3 from rotating excessively due to excessive power output, which would damage the motor 5. It also ensures that the rack 222 can re-engage when the gear rotates, thereby improving the reliability and service life of the disc brake lock and solving the technical problem that traditional disc brake locks are easily damaged due to motor 5 overload or locking pin jamming.

[0030] Optionally, the elastic force of the elastic element can be provided by a spring, elastic band, elastic cylinder or magnetic block, and the specific implementation process will not be described here.

[0031] In addition to the feasible implementation methods described above, such as Figures 3-5As shown, the locking pin push block 23 is provided with a connected spring housing 232 and a slide groove 231. The radial width of the spring housing 232 is greater than the radial width of the slide groove 231. An elastic element is fitted on the rack transmission component 22 and the elastic element is limited within the spring housing 232. When the drive gear set 3 rotates under overload, the rack transmission component 22 slides in the slide groove 231 and is reset by means of the elastic element. The rack transmission component 22 slides back and forth in the slide groove 231, forming a clutch protection for the drive gear set 3.

[0032] In the specific implementation of the above embodiment, the return spring 21 is assembled to the rack and pinion drive 22 within the spring housing 232 and through the first receiving groove 221. When the rack and pinion drive 22 is moved by force, the return spring 21 is pre-compressed within the first receiving groove 221 and simultaneously transmits elastic force to the spring housing 232 through the spring pins at both ends, forming a double elastic support and transmitting the driving force to the rack and pinion drive 22, thereby driving the locking pin body 1 to move. When the locking pin body 1 is at its maximum stroke, the return spring 21 is compressed to its shortest length, so that the two ends of the rack 222 press against the drive gear set 3, so that the drive gear set 3 meshes with the rack 222 during rotation, thereby facilitating the stable meshing of the drive gear set 3 and the rack 222.

[0033] Based on the above embodiments, in a more preferred embodiment, the elastic element is a return spring 21, the outer diameter of which is adapted to the radial width of the spring housing 232; spring pins are provided at the bottom of the rack and pinion drive component 22 for respectively mounting the two ends of the return spring 21. The two spring pins can prevent radial displacement of the return spring 21 while maintaining axial elastic freedom, thereby ensuring that the return spring 21 can accurately cooperate with the spring housing 232 and the first receiving groove 221, making the entire movement stroke of the elastic element more stable and reliable.

[0034] Based on the above embodiments, slide grooves 231 are respectively connected to both ends of the spring housing 232 to provide clutch protection for the drive gear set 3 in both the first and second states of the locking pin body 1. This provides redundant space for the elastic sliding of the rack and pinion transmission component 22 and limits the movement path of the locking pin body 1.

[0035] In addition to the feasible implementation methods described above, to improve the space utilization of the entire disc brake lock, the rack and pinion drive component 22 and the rack 222 are integrally formed. Preferably, the rack and pinion drive component 22 and the rack 222 are bent to fully utilize the assembly space of the lock housing 6. In this embodiment, the integrally connected rack 222 and rack and pinion drive component 22 can improve the stability during the force transmission process and prevent excessive loss during the transmission of the driving force of the rack 222 to the lock pin body 1. At the same time, the bent integral connector can maximize the use of the narrow space within the lock housing 6, ensuring the stability and reliability of the transmission structure while improving the compactness and consistency of the entire disc brake lock.

[0036] For the drive gear set 3, it includes a motor 5, a worm gear assembled with the output end of the motor 5, and a gear set meshing with the worm gear; a micro switch 8 is provided on the side of the locking pin push block 23 away from the elastic clutch assembly 2, and a touch protrusion 233 corresponding to the micro switch 8 is provided on the locking pin push block 23. When the locking pin body 1 is in the unlocking or locking position, the touch protrusion 233 touches or disengages from the micro switch 8 to form a signal feedback. Meanwhile, the disc brake lock also includes a plastic-encased shell 7 disposed within the lock housing 6. The drive gear set 3, micro switch 8, and matching control circuit board are disposed within the plastic-encased shell 7. The final gear, rack 222, and elastic clutch assembly 2 of the drive gear set 3 are disposed between the plastic-encased shell 7 and the lock housing 6. A cable outlet box is also provided on the side of the lock housing 6 away from the locking pin body 1, and the cable outlet box has an S-shaped or bent wire harness groove. An L-shaped reinforcing plate 61 is also provided at the end of the lock housing 6 where the locking pin outlet is located. The L-shaped reinforcing plate 61 has an avoidance hole that is adapted to the guide of the locking pin body 1. With the above configuration, this embodiment, through the transmission adaptation of the gear set and worm gear, achieves a preset reduction ratio while optimizing the transmission path of the driving force, solving the problem of poor driving force transmission in narrow spaces. Furthermore, in this embodiment, the touch protrusion 233 and the micro switch 8 cooperate to trigger the switch state switching using the axial displacement of the locking pin, forming a displacement and electrical signal conversion mechanism. A real-time position feedback closed loop is established through the control circuit board, enabling the control system to accurately perceive the actual state of the locking pin, thereby eliminating misjudgments and providing real-time information on the state of the locking pin body 1. Simultaneously, the reinforcing plate 61 strengthens the local structure, preventing damage to the disc brake lock structure caused by the forced movement of the two-wheeled vehicle when the locking pin is in the locked state. The cable tray inside the cable outlet box optimizes the routing path of the cable harness within the disc brake lock, solving the technical problems of excessive space occupied by the cable harness and easy shaking due to vehicle vibration.

[0037] Furthermore, in the disc brake lock of the above embodiments, the axial direction of the locking pin body 1 can be parallel to the axial direction of the disc brake disc, so as to directly insert into the heat dissipation hole or weight reduction hole of the disc brake disc, thereby forming a lock on the disc brake disc. Alternatively, it can extend radially along the disc brake disc. For this embodiment, please refer to the following for details: Based on the same inventive concept, a disc brake lock assembly system equipped with the aforementioned disc brake lock includes a mounting plate 4 mounted on the wheel hub and a disc brake lock assembly compartment located at the front end of the mounting plate 4. The mounting plate 4 rotates synchronously with the wheel hub and the disc brake disc. Multiple locking grooves are evenly arranged around its own axis on the outer periphery of the mounting plate 4, and these locking grooves are fitted into the locking pin body 1. The assembly compartment is an inner groove located on the rear swingarm. The mounting plate 4 rotates synchronously with the wheel hub and the disc brake disc, forming a dynamic engagement relationship with the locking pin through the circumferentially distributed locking grooves. When the locking pin extends into any locking groove, multi-angle locking is achieved using the inertial torque of the rotating components. This significantly expands the effective locking range, allowing the vehicle to quickly enter the locking state from any stopping position, improving the practicality and response speed of the lock. It eliminates the need for significant wheel hub rotation based on the relative relationship between the locking pin body 1 and the wheel hub, thus solving the problem of inconvenient operation requiring adjustment of the wheel angle for single-point locking.

[0038] Of course, directly opening a locking groove on the outer periphery of the disc brake disc is also a feasible implementation method, which will not be elaborated here.

[0039] Based on the same inventive concept, another objective of this utility model is to provide a two-wheeled vehicle that includes the disc brake lock or disc brake lock assembly system mentioned above.

[0040] Compared to existing technologies, the two-wheeled vehicle of this invention possesses all the advantages of the aforementioned disc brake locks, which will not be elaborated upon here. Furthermore, this invention integrates the elastic locking mechanism into the vehicle's braking system, forming a mechatronic anti-theft solution. It enables intelligent linkage between the locking action and the status of the two-wheeled vehicle, such as a bicycle, electric bicycle, electric-assisted bicycle, or motorcycle. Moreover, this two-wheeled vehicle is compatible with various power outputs for vehicle locks, improving the compatibility of the two-wheeled vehicle with power supplies and automatic disc brake locks.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
