[0002] This application claims the priority of a Chinese patent application with an application date of September 10, 2024, an application number of 202422213743.9, and an application title of "A Bicycle Hook Lock", the entire content of which is incorporated herein by reference. Technical Field

[0003] This application relates to the field of vehicle technologies, particularly to the field of electric assist bicycles, and specifically to a lock and a bicycle. Background Art

[0004] Due to the need to park bicycles outdoors frequently, bicycle locks are usually provided, which restrict the movement of the vehicle physically or electronically and are the most direct anti-theft means. There are various types of bicycle locks, and different locks have their own advantages and disadvantages in terms of anti-theft performance, portability, and applicable scenarios.

[0005] Among them, setting a lock hole on the wheel hub and locking it is becoming increasingly popular because it does not require additional external space, is convenient for users to operate, and is not easily damaged externally. However, the locks of this solution generally have a strong mechanical alignment dependence, that is, it is required that the lock tongue and the lock hole be strictly aligned to lock. If the wheel rotates without precise alignment, users often need to adjust the position to achieve locking, resulting in poor user experience and potential safety hazards. Especially for electronic locks, they usually use electromagnetic drive to directly lock. If the lock tongue is not aligned with the lock hole at the moment of triggering, it is easy to cause wear of the lock pin or motor stall, reducing reliability during long-term use and possibly causing equipment damage. Especially for electric assist bicycles, due to the extensive use of electric control operations, if manual debugging is required, it will bring great disadvantages to the user experience.

[0045] Referring to Figure 1 , Figure 1 FIG. shows a partial structural schematic diagram of a bicycle 10 in an embodiment of the present application. In an embodiment of the present application, a bicycle 10 is provided, which can be any type of bicycle 10 such as a shared bicycle, an electric assist bicycle, a tricycle, a quadricycle, etc., without limitation. It should be noted that only some components of the bicycle 10 are shown in the drawings of the present application for illustration, and the component structures of other parts of the bicycle 10 are not limited.

[0046] As Figure 1 shown, the bicycle 10 includes a frame 200, a rear wheel 400, a claw 300 and a lock plate 500. Among them, the claw 300 is connected between the frame 200 and the rear wheel 400. It should be noted that in the illustration of the application, only the rotating shaft part of the rear wheel 400 is shown for position indication. Combining Figure 2 shown, the lock plate 500 is coaxially rotatably disposed with the rear wheel 400. As Figure 1 and Figure 2 shown, the bicycle 10 further includes a lock 100 as in any of the following embodiments. The lock 100 is connected to the claw 300. As Figure 1 shown, the lock 100 is located inside the claw 300, and it is difficult to see the lock 100 from the outside, so as to achieve a hidden installation and make the overall appearance of the bicycle 10 more coordinated. As Figure 2 shown, at least one locking hole 510 adapted to a locking tongue 132 in the following lock 100 is provided on the circumferential surface of the lock plate 500. As Figure 2 shown, in this embodiment, the lock plate 500 is provided with a plurality of locking holes 510 distributed circumferentially, and each locking hole 510 extends along the radial direction of the lock plate 500. And in this embodiment, the intervals between adjacent locking holes 510 are equal. In Figure 2 , the case where the lock plate 500 is provided with 6 locking holes 510 is taken as an example for illustration, but it is not limited. The number of locking holes 510 is not limited.

[0047] Combining Figure 3As shown, in one embodiment of the present application, a lock 100 is provided. The lock 100 includes a driving source 110, a driving push block 120, a driven assembly 130, and an elastic transmission member 140. Among them, the driving source 110 is used to provide the power for the movement of the driving push block 120. In this embodiment, the driving source 110 is a driving motor, but it is not limited thereto. In other embodiments, the driving source 110 may also be other mechanisms such as an internal combustion engine, etc.

[0048] The driving push block 120 is in transmission connection with the driving source 110. Combining Figure 3 and Figure 4 As shown, in one embodiment, the lock 100 further includes a transmission gear set 180. The transmission gear set 180 is in transmission connection between the driving source 110 and the driving push block 120. In this embodiment, the transmission gear set 180 includes a plurality of meshing gears, which together form a reduction gear set. As Figure 3 and Figure 4 shown, the driving push block 120 is provided with teeth 123 for meshing and transmitting with the transmission gear set 180, so that the driving source 110 can drive a plurality of secondary gears including a secondary turbine through a worm, and then drive the driving push block 120 to move. In other embodiments, the driving source 110 may also directly connect to the driving push block 120 through other transmission structures.

[0049] Combining Figure 5 and Figure 6 shown, the driving push block 120 is configured to be able to move between a first position as shown in Figure 5 and a second position as shown in Figure 6 under the drive of the driving source 110. The driven assembly 130 includes a driven push block 131 and a lock tongue 132 connected to each other. The driven assembly 130 is configured to be able to move between a locking position as shown in Figure 6 and an unlocking position as shown in Figure 5 .

[0050] As Figure 5 and Figure 6 shown, in one embodiment, the lock 100 further includes a housing 170. The driving push block 120 and the driven push block 131 are both located inside the housing 170. And when the driven push block 131 is in the locking position, at least a part of the lock tongue 132 extends out of the housing 170, so as to be inserted into a locking hole 510 located outside the housing 170. In this embodiment, the driving source 110 and the transmission gear set 180 are also located inside the housing 170, but it is not limited thereto.

[0051] As Figures 3 to 5As shown, the elastic transmission member 140 is drivingly connected between the active push block 120 and the driven push block 131. When the active push block 120 moves, the elastic transmission member 140 deforms. The elastic force formed by the deformation of the elastic transmission member 140 drives the driven push block 131 to move. It can be understood that correspondingly, at this time, the elastic transmission member 140 also has a thrust on the active push block 120. However, since the thrust of the elastic transmission member 140 on the active push block 120 is less than the force of the meshing transmission between the teeth 123 and the transmission gear set 180, during the normal locking and unlocking processes, the elastic transmission member 140 only serves to drive the driven push block 131 to move between the unlocking position and the locking position.

[0052] When the active push block 120 is in the second position as shown in Figure 6 the elastic transmission member 140 has a tendency to drive the driven assembly 130 to move to the locking position. If the locking hole 510 is aligned with the locking tongue 132 at this time, the elastic transmission member 140 can directly drive the driven assembly 130 to move to the locking position. At this time, the locking tongue 132 is partially inserted into the locking hole 510 to lock the bicycle 10. However, if the locking hole 510 is not aligned with the locking tongue 132 at this time, the elastic transmission member 140 maintains its elastic force to drive the driven assembly 130 to move to the locking position until the lock disk 500 rotates to align the locking hole 510 with the locking tongue 132, and then drives the driven assembly 130 to move to the locking position to lock the bicycle.

[0053] In one embodiment, when the active push block 120 moves between the first position as shown in Figure 5 and the second position as shown in Figure 6 the moving direction is the same as the axial direction of the elastic transmission member 140. At this time, the movement of the active push block 120 directly compresses the elastic transmission member 140.

[0054] In one embodiment, when the driven assembly 130 moves between the locking position as shown in Figure 6 and the unlocking position as shown in Figure 5 the moving direction is the same as the axial direction of the elastic transmission member 140. At this time, the force exerted by the elastic transmission member 140 on the driven assembly 130 is consistent with the moving direction of the driven assembly 130.

[0055] As shown in Figures 5 to 8 in one embodiment, the elastic transmission member 140 is located between the first position of the active push block 120 as shown in Figure 5 and the second position as shown in Figure 6On the path of the second position movement shown, and on the path of the active push block 120 moving from the second position to the first position. At the same time, the elastic transmission member 140 is on the path of the active push block 120 moving from the locked position to the unlocked position, and on the path of the active push block 120 moving from the unlocked position to the locked position. When the active push block 120 moves relative to the driven push block 131, regardless of the moving direction, that is, regardless of moving from the first position shown as Figure 5 to the second position shown as Figure 6 or moving from the second position to the first position, the elastic transmission member 140 can be compressed, so that the elastic transmission member 140 generates an elastic force to drive the driven push block 131 to move in the same direction as the active push block 120 or drive the active push block 120 to reset.

[0056] As Figures 7 to 9 shown, in one embodiment, the driven push block 131 is provided with a groove 1311, and a part of the elastic transmission member 140 is placed in the groove 1311. The axial direction of the elastic transmission member 140 is consistent with the moving directions of the driven push block 131 and the active push block 120. And as Figure 7 and Figure 9 shown, the active push block 120 is provided with a placement groove 121 arranged along the axial direction of the elastic transmission member 140 and an abutting groove 122 communicated with the placement groove 121. As Figure 8 and Figure 9 shown, a part of the driven push block 131 is inserted into the placement groove 121, and at least a part of the part of the elastic transmission member 140 protruding from the groove 1311 is located in the abutting groove 122, so that when the active push block 120 moves, the elastic transmission member 140 can be compressed, thereby making the elastic transmission member 140 generate an elastic force.

[0057] As Figure 7 and Figure 9 shown, in one embodiment, the driven push block 131 includes positioning blocks 1312. The two positioning blocks 1312 respectively protrude from the two groove walls of the groove 1311 opposite to each other in the axial direction of the elastic transmission member 140, and the two positioning blocks 1312 are spaced apart in the axial direction of the elastic transmission member 140. The two ends of the elastic transmission member 140 are respectively sleeved on the outer peripheries of the two positioning blocks 1312, so as to facilitate the installation of the elastic transmission member 140 between the two positioning blocks 1312. The installation process is simple, does not hurt the hands, and is unstable after installation and not easy to come out.

[0058] As Figure 7As shown, in one embodiment, each positioning block 1312 tapers in size from the groove wall of the groove 1311 to the direction where the other positioning block 1312 is located, facilitating the installation of the elastic transmission member 140. In this embodiment, the width of the positioning block 1312 tapers in the planes opposite to each other on both sides, so that it forms four sides, and the four sides can be sleeved and contacted with the inner side of the elastic transmission member 140 such as a spring, thus better achieving fixation. In other embodiments, the positioning block 1312 can also be structures such as a cone or a frustum of a cone, which can all achieve the abutment against the inner wall of the elastic transmission member 140, ensuring the connection stability between the elastic transmission member 140 and the positioning block 1312.

[0059] As Figure 3 , Figure 5 and Figure 6 As shown, in one embodiment, the lock 100 further includes a first position detector 151. The first position detector 151 is located on one side of the moving path of the driven assembly 130 and is configured to be triggered when the driven assembly 130 is in the unlocked position, enabling the user to confirm the position of the driven assembly 130 according to the signal of the first position detector 151.

[0060] In one embodiment, the lock 100 further includes a second position detector 152. The second position detector 152 is located on one side of the moving path of the driven assembly 130 and is configured to be triggered when the driven assembly 130 is in the locked position, enabling the user to jointly confirm the state of the lock 100 according to the signal of the second position detector 152 in combination with the signals of the first position detector 151 and the drive source 110.

[0061] For example, when the drive source 110 is activated and drives the active push block 120 to move towards the second position, if the locking hole 510 is aligned with the locking tongue 132 at this time, the elastic transmission member 140 can directly drive the driven assembly 130 to move to the locked position and trigger the second position detector 152. At this time, the drive source 110 is activated and used for locking. The first position detector 151 is not triggered, and the second position detector 152 is triggered, then the lock 100 is in the locked state.

[0062] When the drive source 110 is activated and drives the active push block 120 to move towards the second position, if the locking hole 510 is not aligned with the locking tongue 132 at this time, the elastic transmission member 140 cannot directly drive the driven assembly 130 to move to the locked position, and at this time the first position detector 151 remains in the triggered state. At this time, the drive source 110 is activated and used for locking. The first position detector 151 is triggered, and the second position detector 152 is not triggered, then the lock 100 is in the pre-locked state, that is, when the lock plate 500 rotates to align the locking hole 510 with the locking tongue 132, it automatically switches to the locked state.

[0063] When the driving source 110 is activated and drives the active pushing block 120 to move towards the first position, the elastic transmission member 140 drives the driven assembly 130 to move to the unlocking position. At this time, the first position detector 151 switches to the triggered state. At this time, the driving source 110 is activated and used for unlocking. The first position detector 151 is triggered, and the second position detector 152 is not triggered, then the lock 100 is in the unlocked state.

[0064] It should be noted that the types of the first position detector 151 and the second position detector 152 are not limited. They can be a leaf type limit switch, a Hall induction sensor, or any other object capable of monitoring the position. In the attached drawings of this specification, the case where both the first position detector 151 and the second position detector 152 are leaf type limit switches is taken as an example for illustration, but it is not a limitation. At the same time, it is not limited that the first position detector 151 and the second position detector 152 are of the same type of position detection element.

[0065] Exemplarily, in this embodiment, the second position detector 152 is located below the driven pushing block 131, and the second position detector 152 is a leaf type limit switch. Its leaf is located on the moving path of the driven pushing block 131 moving to the locking position and can trigger a position signal when the driven pushing block 131 is in the locking position.

[0066] Such as Figure 3 、 Figure 5 and Figure 6 shown, in one embodiment, the first position detector 151 is located on the extended path of the moving path of the driven assembly 130 from the locking position as shown in Figure 6 to the unlocking position as shown in Figure 5 . And when the driven assembly 130 is in the unlocking position as shown in Figure 5 , it abuts against the first position detector 151 to limit the position of the driven pushing block 131 through the first position detector 151.

[0067] Such as Figure 3 and Figure 4 shown, in one embodiment, the lock 100 further includes an elastic member 160. The elastic member 160 acts on the driven assembly 130, and the elastic member 160 has a tendency to drive the driven assembly 130 to move to the unlocking position, so as to prevent the driven assembly 130 from accidentally sliding into the lock hole for mislocking (such as the driven pushing block 131 breaking, the lock tongue 132 disengaging from the clamping portion of the driven pushing block 131, etc.), and avoid accidents during driving. In this embodiment, the two ends of the elastic member 160 respectively abut against the driven pushing block 131 and the inner wall of the housing 170, so that the elastic member 160 is compressed when the driven assembly 130 is in the locking position, thereby realizing that the elastic member 160 has a force to drive the driven assembly 130 to move to the unlocking position.

[0068] As Figure 5 shown, in one embodiment, there is a gap between the active push block 120 in the first position and the inner wall of the housing 170. The active push block 120 can continue to move on the extended path of the movement path from the second position to the first position, so that when the active push block 120 has moved to the first position, if the drive source 110 is not timely turned off, the drive source 110 can continue to drive the active push block 120 to move, and the drive source 110 will not be blocked due to the lack of space for the active push block 120 to continue to displace.

[0069] Moreover, in this embodiment, the length and number of the teeth 123 on the active push block 120 that can mesh and drive with the transmission gear set 180 are limited. When the active push block 120 continues to move on the extended path of the movement path from the second position to the first position, the teeth 123 are disengaged from the transmission gear set 180, so that the drive source 110 can continue to rotate without being blocked, achieving the effect of preventing blockage. At the same time, since the active push block 120 continues to move, but the driven push block 131 is limited by the position of the first position detector 151 and cannot move synchronously, the active push block 120 and the driven push block 131 will compress the elastic transmission member 140. When the teeth 123 are disengaged from the transmission gear set 180, the elastic transmission member 140 can drive the active push block 120 to reset to the first position, so that the teeth 123 and the transmission gear set 180 are engaged again, facilitating the lock 100 to switch to the locked state.

[0070] Exemplarily, as Figure 4 、 Figure 7 and Figure 8 shown, in this embodiment, the number of the teeth 123 on the rack provided on the active push block 120 is 4, but this is not a limitation. Preferably, the distance that the transmission gear set 180 can drive the active push block 120 to move when meshing with the teeth 123 is less than the maximum distance that the active push block 120 can move in the housing 170, so that when the active push block 120 exceeds the second position when locked or exceeds the first position when unlocked, the teeth 123 can be timely disengaged from the transmission gear set 180, thereby obtaining a better effect of preventing the drive source 110 from being blocked.

[0071] In one embodiment, there is a gap between the active push block 120 in the second position and the inner wall of the housing 170. The active push block 120 can continue to move on the extended path of the movement path from the first position to the second position, so that when the active push block 120 has moved to the second position, if the drive source 110 is not timely turned off, the drive source 110 can continue to drive the active push block 120 to move, and the drive source 110 will not be blocked due to the lack of space for the active push block 120 to continue to displace.

[0072] Moreover, in this embodiment, the length and number of the teeth 123 on the active push block 120 that can mesh with the transmission gear set 180 are limited. When the active push block 120 continues to move along the extended path of the movement path from the first position to the second position, the teeth 123 disengage from the transmission gear set 180, enabling the drive source 110 to continue rotating without stalling, thus achieving the effect of preventing stalling. At the same time, since the active push block 120 continues to move, but the driven push block 131 has reached the unlocking position and cannot continue to move due to the limitation of the housing 170, the active push block 120 and the driven push block 131 will compress the elastic transmission member 140. After the teeth 123 disengage from the transmission gear set 180, the elastic transmission member 140 can drive the active push block 120 to reset to the second position, thereby enabling the teeth 123 to mesh with the transmission gear set 180 again, facilitating the lock 100 to switch to the unlocked state.

[0073] Combined with Figures 10 to 13 As shown in the figure, in another embodiment of the present application, a lock 100 is provided, which is different from the above embodiment in that: as Figure 11 shown, a limiting groove 1321 is recessed on the circumferential surface of the lock tongue 132. The lock 100 further includes a movable limiting component 191. The limiting component 191 is located in the limiting groove 1321 of the lock tongue 132 in the unlocking position as shown in Figure 11 the figure, and combined with Figure 12 and Figure 13 shown, the limiting component 191 is configured to be able to move relative to the lock tongue 132 to partially insert into and withdraw from the limiting groove 1321. When the limiting component 191 partially inserts into the limiting groove 1321, the limiting component 191 can restrict the movement of the lock tongue 132, keeping the lock tongue 132 in the unlocking position, thus preventing the driven component 130 from being accidentally locked due to abnormalities such as the fracture of the driven push block 131.

[0074] Generally speaking, compared with the rigid connection between the active push block 120 and the driven push block 131, if the situation occurs that the active push block 120 has reached the first position or the second position, but the drive source 110 fails to stop outputting torque in time and continues to rotate, as a transmission component 1912, the elastic transmission member 140 can prevent the transmission gear set 180 and the teeth 123 from being crushed or the drive source 110 from being damaged due to overload. Moreover, after the elastic transmission member 140 is compressed, it can use the elastic force to reset the teeth 123 and the transmission gear set 180 to maintain the meshing transmission state, thereby reducing the damage of the drive source 110 or the mechanical structure and improving the service life.

[0075] As Figures 11 to 13 shown, in one of the embodiments, the bicycle 10 further includes a footrest 600 rotatably connected to the frame 200. The footrest 600 is configured to be able to be in the retracted position as shown by the solid line in Figure 10 and the position as shown by the solid line in Figure 10It can rotate between the support positions shown by the dashed lines. It can be understood that, usually, when the bicycle 10 needs to move, the footrest 600 will be moved to the retracted position. As Figure 13 shown, the limiting component 191 is located on the moving path of the footrest 600 from the self-supporting position to the retracted position. When the footrest 600 moves to the retracted position, the limiting component 191 is driven to partially insert into the limiting groove 1321, so that when the bicycle 10 needs to be ridden, the limiting component 191 can limit the movement of the locking tongue 132, thereby avoiding the effect of accidental locking.

[0076] As Figure 12 and Figure 13 shown, in one embodiment, the lock 100 further includes a first elastic reset member 192. The first elastic reset member 192 acts on the limiting component 191 and has a tendency to drive the limiting component 191 to withdraw from the limiting groove 1321, so that when the footrest 600 is reset to the self-supporting position, the first elastic member 160 can drive the limiting component 191 to withdraw from the limiting groove 1321, and avoid interfering with the movement of the locking tongue 132 to the locking position, thereby avoiding the lock 100 from switching to the locked state.

[0077] As Figure 12 and 13 shown, in this embodiment, the limiting component 191 includes a transmission part 1912 and a limiting part 1911. The transmission part 1912 is located on the moving path of the footrest 600 from the self-supporting position to the retracted position. When the footrest 600 moves to the retracted position, the footrest 600 drives the transmission part 1912 to move towards the direction where the limiting part 1911 is located, and drives the limiting component 191 to move to insert into the limiting groove 1321.

[0078] As Figure 12 and Figure 13 shown, in this embodiment, the lock 100 further includes a connecting shell 193. The connecting shell 193 is connected to the shell 170, and the connecting shell 193 is provided with a guiding hole for the movement of the transmission part 1912, so that the transmission part 1912 moves along a preset direction.

[0079] As Figure 12 and Figure 13 shown, in this embodiment, the lock 100 further includes a second elastic reset member 194. The second elastic reset member 194 acts between the transmission part 1912 and the connecting shell 193, and the second elastic reset member 194 has a tendency to drive the transmission part 1912 to reset to a position where it is partially located on the moving path of the footrest 600 from the self-supporting position to the retracted position, so that when the footrest 600 switches to the retracted position next time, it can still drive the transmission part 1912 to move, and further drive the limiting part 1911 to insert into the limiting groove 1321.

[0080] In the lock 100 provided in the above solution, the elastic transmission member 140 is arranged between the active push block 120 and the driven push block 131 to achieve the transmission connection between the two. On the one hand, the locking timing of the lock 100 is no longer restricted to the alignment of the locking hole 510 and the locking tongue 132. It can achieve pre-locking when the locking hole 510 and the locking tongue 132 are not aligned, and immediately lock the vehicle when the lock disc 500 rotates, improving the convenience of using the lock 100 while ensuring safety. On the other hand, the elastic transmission between the active push block 120 and the driven push block 131, compared with the rigid connection between the active push block 120 and the driven push block 131, if the situation occurs that the active push block 120 has reached the first position or the second position, but the drive source 110 fails to stop outputting torque in time and continues to rotate, the elastic transmission member 140, as the transmission component 1912, can avoid the extrusion and damage of the transmission gear set 180 and the tooth 123 or the overload damage of the drive source 110. Moreover, after the elastic transmission member 140 is compressed, it can use the elastic force to reset the tooth 123 and the transmission gear set 180 to maintain the meshing transmission state, thereby reducing the damage of the drive source 110 or the mechanical structure and improving the service life.
