[0115] The application provides a vehicle lock assembly arranged in a tire of a vehicle, which comprises a driving mechanism, an output mechanism and a self-locking transmission mechanism; the driving mechanism is mounted on a tire shaft and coaxially arranged with the tire shaft at an output end; the output mechanism is fixedly mounted on the tire; the self-locking transmission mechanism is mounted on the tire shaft, and an input end of the self-locking transmission mechanism is connected with the output end of the driving mechanism, and an output end of the self-locking transmission mechanism is connected with the output mechanism; the self-locking transmission mechanism is used to transmit the driving force provided by the driving mechanism to the output mechanism to drive the tire to rotate; and after the driving mechanism stops running, the self-locking transmission mechanism can lock the output mechanism through self-locking. The vehicle lock assembly is provided with the self-locking transmission mechanism, and the driving force of the driving mechanism can be transmitted to the output mechanism through the transmission of the self-locking transmission mechanism, so as to drive the tire to normally rotate. When an unexpected situation occurs, after the driving mechanism is powered off, the self-locking transmission mechanism can lock the tire through the self-locking function of the self-locking transmission mechanism, so that an additional locking structure is not needed, the locking of the tire can be realized through the self-locking of the transmission component, the structural components needed to be arranged on the tire are reduced, the installation space needed by the overall structure of the vehicle lock assembly is smaller, and the vehicle lock assembly can be arranged in the tire. The vehicle lock assembly is arranged in the tire of the vehicle and forms an integral structure with the tire, so that the overall structure is more compact, and the overall structure size of the tire part after installation is reduced.

[0116] Please refer to Figures 1 to 4 and Figure 12The embodiment provides a vehicle lock assembly 100 arranged in a tire 200 of a vehicle, the vehicle lock assembly 100 comprising a driving mechanism 10, an output mechanism 20 and a self-locking transmission mechanism 30, the driving mechanism 10 is arranged on a tire shaft 300, and the output end of the driving mechanism 10 is coaxially arranged with the tire shaft 300, that is, the central axis of the output end of the driving mechanism 10 is located on the same straight line as the central axis of the tire shaft 300, so that the volume space required by the driving mechanism 10 can be further compressed. The output mechanism 20 is fixedly arranged on the tire 200, the self-locking transmission mechanism 30 is arranged on the tire shaft 300, the input end of the self-locking transmission mechanism 30 is connected with the output end of the driving mechanism 10, and the output end of the self-locking transmission mechanism 30 is connected with the output mechanism 20. It should be noted that the input end of a component refers to that when the component is regarded as a whole, the end through which the driving force flows into the component is the input end of the component, and the output end of a component refers to that when the component is regarded as a whole, the end through which the driving force flows out of the component is the output end of the component. In addition, it should be noted that a component is fixedly arranged on another component refers to that when the component is driven to operate, the component can synchronously drive the other component to operate, and the connecting structure actually adopted can be a non-detachable structure or a detachable structure, which can be selected according to actual requirements.

[0117] The self-locking transmission mechanism 30 is used for transmitting the driving force provided by the driving mechanism 10 to the output mechanism 20, so as to drive the tire 200 to rotate. That is, the driving mechanism 10 is used for providing the driving force to the self-locking transmission mechanism 30, the driving force is transmitted to the output mechanism 20 through the self-locking transmission mechanism 30, and since the output mechanism 20 is fixedly arranged on the tire 200, the driving force drives the output mechanism 20 to rotate and simultaneously drives the tire 200 to rotate, so that the running of the tire 200 is realized.

[0118] When the driving mechanism 10 stops operating, the self-locking transmission mechanism 30 locks the output mechanism 20 through self-locking. That is, when the driving mechanism 10 stops operating, the self-locking transmission mechanism 30 can lock the whole structure through self-locking between the transmission units in the self-locking transmission mechanism 30, so as to lock the output mechanism 20, so that the output mechanism 20 cannot rotate any more, and since the output mechanism 20 is fixedly arranged on the tire 200, the tire 200 is simultaneously locked, so that the locking function of the vehicle lock assembly 100 is realized.

[0119] It can be understood that the driving device of the tire and the locking device of the tire in the prior art are two independent devices, and the locking device of the tire is connected and arranged outside the tire, and the locking of the tire is realized by additionally arranging the corresponding locking structure. Since the locking device of the tire is independently arranged, an independent locking structure and an unlocking structure need to be arranged, the installation space required by the whole is large, so that the existing locking device of the tire can only be installed outside the tire. This structure also leads to the overall structure of the tire part of the vehicle being large.

[0120] The vehicle lock assembly 100 provided by the embodiment can realize driving and locking of the tire 200. The driving device and the locking device of the tire are integrated, the components required to be arranged are reduced, the output end of the driving mechanism 10 is coaxially arranged with the tire shaft 300, the volume space required to be occupied is further reduced, the overall structure is simplified, the overall structure is more compact and small, and the vehicle lock assembly 100 can be installed in the tire 200. The vehicle lock assembly 100 is directly installed by using the tire shaft 300, and the components required to be arranged can be further reduced, so that the installation space required to be occupied is smaller. After the vehicle lock assembly 100 is installed in the tire 200, the overall structure is further compact and small, and the integration degree is higher. The self-locking transmission mechanism 30 is used for transmission, when the vehicle needs to run, the driving mechanism 10 can provide driving force, and the self-locking transmission mechanism 30 can be used for transmission to realize running of the tire 200; when the vehicle needs to be locked, the tire can be locked by self-locking of the self-locking transmission mechanism 30, and no additional locking structure is needed, so that the overall structure is further simplified.

[0121] When the vehicle lock assembly 100 is applied to the vehicle, when the vehicle normally runs, the driving mechanism 10 is powered on and runs to provide driving force, the driving force is transmitted to the output mechanism 20 through the self-locking transmission mechanism 30 driven by the driving mechanism 10, the tire 200 is driven to rotate by the output mechanism 20, and the vehicle runs; when an unexpected situation occurs, the driving mechanism 10 is powered off, the driving mechanism 10 no longer provides driving force to the self-locking transmission mechanism 30, the transmission units in the self-locking transmission mechanism 30 are self-locked, the output mechanism 20 is locked, the tire 200 cannot run any more, and the vehicle is locked.

When the driving mechanism 10 is powered, the stator 11 drives the rotor 12 to rotate on the tire shaft 300, so as to transmit the rotating driving force to the self-locking transmission mechanism 30 and drive the self-locking transmission mechanism 30 to operate. Through such a structure, the driving mechanism 10 can more stably provide driving force to the self-locking transmission mechanism 30.

The third steering transmission unit 3226 is connected with the second steering transmission unit 3225 to change the transmission direction in cooperation with the second steering transmission unit 3225. In this embodiment, when the driving mechanism 10 provides driving force, the driving force is transmitted to the first transmission unit 3222 via the input unit 31, then synchronously transmitted to the second steering transmission unit 3225 by the first transmission shaft 3221, the transmission direction is changed by cooperation between the second steering transmission unit 3225 and the third steering transmission unit 3226, at the same time the third steering transmission unit 3226 drives the second transmission shaft 3224 to rotate, and then transmitted to the output unit 33, and the driving force is transmitted to the output mechanism 20 through the output unit 33.

[0129] Specifically, in one embodiment, the second steering transmission unit 3225 and the third steering transmission unit 3226 are bevel gears, and the second steering transmission unit 3225 meshes with the third steering transmission unit 3226. More specifically, in one embodiment, the output unit 33 is a spur gear, and the output mechanism 20 is an inner ring gear, and the output unit 33 meshes with the output mechanism 20, thereby forming a three-stage speed reduction structure to realize the transmission of driving force.

Preferably, in another embodiment, the connecting structure between the output unit 33 and the output mechanism 20, and the specific structure of the transmission transmission structure 3223 can also be: the output unit 33 is a steering transmission unit, and the output unit 33 is used to change the transmission direction in cooperation with the output mechanism 20. The power transmission unit group 322 further includes a third transmission shaft 3224', which is rotatably mounted to the mounting bracket 321 and corresponds to the output unit 33. The power transmission structure 3223 includes a second transmission unit 3225' and a third transmission unit 3226', the second transmission unit 3225' is fixedly mounted to the first transmission shaft 3221, the third transmission unit 3226' is fixedly mounted to the third transmission shaft 3224', and the third transmission unit 3226' is connected with the second transmission unit 3225'. In this embodiment, when the driving mechanism 10 provides driving force, the driving force is transmitted to the first transmission unit 3222 through the input unit 31, and then synchronously transmitted to the second transmission unit 3225' through the first transmission shaft 3221; then transmitted to the third transmission unit 3226' through the second transmission unit 3225', and then transmitted to the output unit 33 through the third transmission shaft 3224', and the transmission direction is changed through the cooperation between the output unit 33 and the output mechanism 20. That is, in this embodiment, the change of the driving force transmission direction is specifically realized by the cooperation between the output unit 33 and the output mechanism 20. Specifically, in this embodiment, the specific structure of the mounting bracket 321 can be changed accordingly, so that the installation of the third transmission shaft 3224', the second transmission unit 3225' and the third transmission unit 3226' can be better adapted.

[0131] Specifically, in one embodiment, the second transmission unit 3225' and the third transmission unit 3226' are spur gears, and the second transmission unit 3225' meshes with the third transmission unit 3226'. The output mechanism 20 is a gear ring, and the teeth of the output mechanism 20 are arranged on the side surface, and the output unit 33 is a bevel gear, and the output unit 33 meshes with the output mechanism 20, thereby forming a three-stage speed reduction structure to realize the transmission of driving force. Through this structure, the components can be installed and used by standard parts, which can better reduce the cost and ensure the stability during transmission.

[0132] Preferably, in another embodiment, the connecting structure between the output unit 33 and the output mechanism 20, and the specific structure in the transmission unit group 322 can also be that the output unit 33 is a steering transmission unit, and the output unit 33 is used to change the transmission direction in cooperation with the output mechanism 20. The transmission unit group 322 includes a transmission shaft and a transmission unit, the transmission shaft is rotatably installed on the mounting bracket 321 and corresponds to the output unit 33. The transmission unit is fixedly installed on the transmission shaft, and the transmission unit is connected with the input unit 31 and is used to cooperate with the input unit 31 to realize the self-locking of the self-locking transmission mechanism 30. Specifically, the transmission unit and the input unit 31 can adopt a worm gear structure. That is, in this embodiment, the change of the driving force transmission direction is specifically realized by the cooperation between the output unit 33 and the output mechanism 20, and in this embodiment, only one transmission shaft is provided in the transmission unit group 322, and the driving force transmitted by the transmission unit is directly transmitted to the output unit 33 through the transmission shaft.

[0133] Please refer to Figures 5 to 10 and Figure 14 . Preferably, in an embodiment, the output end of the transmission unit group 322 is provided with a clutch 323, and the clutch 323 is used in combination with the output unit 33 to transmit the driving force to the output unit 33. That is, in an embodiment, the transmission unit group 322 transmits the driving force to the output unit 33 specifically through the clutch 323. By providing the clutch 323, the connection and separation between the transmission unit group 322 and the output unit 33 can be realized, so that by controlling the position of the clutch 323, the power transmission path between the output unit 33 and the transmission unit group 322 can be disconnected. Through this structure, the output unit 33 can independently and autonomously operate, and when the driving mechanism 10 stops running and the self-locking transmission mechanism 30 is self-locked, the output unit 33 can be rotated by force by controlling the position of the clutch 323, so as to realize the unlocking of the vehicle lock assembly 100. For example, when the vehicle lock assembly 100 is applied to a vehicle, in the event of an emergency, the driving mechanism 10 is powered off, the vehicle lock assembly 100 locks the tire 200, and manual pushing of the vehicle is required, the clutch 323 can be driven to move, so that the output unit 33 is disconnected from the transmission assembly 32, so that the tire 200 can be unlocked, and the vehicle can be manually pushed to move.

[0134] Specifically, in an embodiment, the clutch 323 is arranged on the output shaft of the transmission unit group 322, and the clutch 323 can move along the axial direction of the output shaft. By moving the clutch 323 along the axial direction of the output shaft, the clutch 323 and the output unit 33 are combined and separated. For example, the clutch 323 can be arranged on the second transmission shaft 3224 or the third transmission shaft 3224' or the transmission shaft.

[0135] Specifically, in an embodiment, the specific combination structure of the clutch 323 and the output unit 33 can be that the clutch 323 is provided with a combination protrusion 3231 on the side close to the output unit 33, the output unit 33 is provided with a combination groove 331 on the side close to the clutch 323, and the combination groove 331 corresponds to the combination protrusion 3231. When combined, the combination protrusion 3231 is inserted into the combination groove 331, and the combination of the clutch 323 and the output unit 33 is achieved.

[0136] Preferably, in an embodiment, the vehicle lock assembly 100 further comprises a manual unlocking mechanism 40, which is installed on the mounting bracket 321 and corresponds to the clutch 323, and is used to drive the clutch 323 to move. The manual unlocking mechanism 40 has an initial state and an unlocking state. When the manual unlocking mechanism 40 is in the initial state, the clutch 323 is combined with the output unit 33; when the manual unlocking mechanism 40 is in the unlocking state, the clutch 323 is separated from the output unit 33. That is, the manual unlocking mechanism 40 is used to drive the clutch 323 to change the position of the clutch 323. When the vehicle lock assembly 100 is in the locked state, the state of the manual unlocking mechanism 40 can be changed by manually driving the manual unlocking mechanism 40, so that the clutch 323 moves and separates from the output unit 33, thereby achieving manual unlocking of the vehicle lock assembly 100, and facilitating manual unlocking operation.

[0137] Specifically, in an embodiment, the specific connection structure between the manual unlocking mechanism 40 and the clutch 323 can be that a ring groove 3232 is formed on the clutch 323, and part of the components of the manual unlocking mechanism 40 is located in the ring groove 3232, and the manual unlocking mechanism 40 drives the clutch 323 to move by abutting against the groove wall of the ring groove 3232.

[0138] Please refer to Figure 10 and Figure 11Preferably, in an embodiment, the manual unlocking mechanism 40 comprises a spring body 41, a control part 42, and a limiting part 43. The spring body 41 is connected with the mounting bracket 321, the control part 42 is connected with the spring body 41, and the control part 42 is arranged corresponding to the clutch 323, and the control part 42 is used to separate the clutch 323 from the output unit 33. The limiting part 43 is connected with the spring body 41, and is used to cooperate with the limiting structure 3211 on the mounting bracket 321 to keep the manual unlocking mechanism 40 in the unlocked state. In this embodiment, by applying force to the spring body 41, the control part 42 and the limiting part 43 can be driven to move synchronously, and during the movement, the control part 42 drives the clutch 323 to move, so that the clutch 323 is separated from the output unit 33; at the same time, during the movement, the limiting part 43 can cooperate with the limiting structure 3211 on the mounting bracket 321 to limit the whole manual unlocking mechanism 40, so as to ensure that the manual unlocking mechanism 40 can remain in the unlocked state. Through this structure, the position of the manual unlocking mechanism 40 can be better maintained, the separation between the clutch 323 and the output unit 33 is ensured, and the accidental locking of the vehicle lock assembly 100 after unlocking is avoided.

[0139] Preferably, in an embodiment, the limiting structure 3211 comprises a limiting groove 3212 and a limiting block 3213, and the limiting groove 3212 is arranged on the mounting bracket 321. The limiting part 43 is inserted into the limiting groove 3212, and the limiting part 43 can slide in the limiting groove 3212. The limiting block 3212 is arranged in the limiting groove 3212 to limit the limiting part 43, so as to keep the manual unlocking mechanism 40 in the unlocked state. That is, in an embodiment, the limiting part 43 is located at different positions in the limiting groove 3212 when the manual unlocking mechanism 40 is in different states. And when the manual unlocking mechanism 40 is in the unlocked state, the limiting block 3213 limits the limiting part 43, so as to keep the manual unlocking mechanism 40 in the unlocked state. Through this structure, the limiting of the limiting structure 3211 on the limiting part 43 can be better guaranteed, and the state of the manual unlocking mechanism 40 can be better maintained.

[0140] Preferably, in an embodiment, the limiting groove 3212 comprises a limiting groove body 3214 and a reset groove 3215 which are in communication with each other. The limiting block 3213 is arranged on the bottom wall of the limiting groove body 3214, and the reset groove 3215 is arranged on one side of the limiting block 3213. When the limiting portion 43 is limited by the limiting block 3213, it can slide into the reset groove 3215 after being stressed, and can slide into the initial position in the limiting groove body 3214 through the reset groove 3215, so as to switch the manual unlocking mechanism 40 to the initial state. That is, in an embodiment, during the switching of the manual unlocking mechanism 40 from the initial state to the unlocked state, the limiting portion 43 slides in the limiting groove body 3214, and when the limiting portion 43 slides to the limiting block 3213, the position of the limiting portion 43 is maintained by limiting the limiting portion 43 by the limiting block 3213, so as to keep the unlocked state of the manual unlocking mechanism 40; and when the manual unlocking mechanism 40 is switched from the unlocked state to the initial state, the limiting portion 43 slides into the reset groove 3215, and the limiting portion 43 is guided by the reset groove 3215 to slide into the initial position in the limiting groove body 3214 again, so as to switch the manual unlocking mechanism 40 to the initial state again. Through this structure, the switching of the manual unlocking mechanism 40 is smoother, and the use experience is improved.

[0141] Preferably, in an embodiment, the limiting groove body 3214 comprises a first portion 3216 and a second portion 3217 which are in communication with each other. When the manual unlocking mechanism 40 is in the initial state, the limiting portion 43 is located in the first portion 3216; when the manual unlocking mechanism 40 is in the unlocked state, the limiting portion 43 is located in the second portion 3217. The reset groove 3215 is in communication with the first portion 3216 and the second portion 3217 respectively, and the bottom wall height of the reset groove 3215 is lower than the bottom wall height of the limiting groove body 3214. That is, the recess depth of the reset groove 3215 is greater than the recess depth of the limiting groove body 3214, so that there is a height difference between the bottom wall of the reset groove 3215 and the bottom wall of the limiting groove body 3214. The bottom wall of the reset groove 3215 and the bottom wall of the second portion 3217 are in step transition, so that there is a step surface 3218 between the bottom wall of the reset groove 3215 and the bottom wall of the second portion 3217. The bottom wall of the reset groove 3215 and the bottom wall of the first portion 3216 are in inclined surface transition, so that there is a transition inclined surface 3219 between the bottom wall of the reset groove 3215 and the bottom wall of the first portion 3216. When the manual unlocking mechanism 40 is switched from the unlocked state to the initial state, the limiting portion 43 first slides into the reset groove 3215 from the second portion 3217, and due to the presence of the step surface 3218, the limiting portion 43 sliding into the reset groove 3215 can be blocked, avoiding the limiting portion 43 from sliding back into the second portion 3217. And due to the presence of the transition inclined surface 3219 between the bottom wall of the reset groove 3215 and the bottom wall of the first portion 3216, the limiting portion 43 can slide into the first portion 3216 along the transition inclined surface 3219. Through this structure, the reliability of the process of switching the manual unlocking mechanism 40 from the unlocked state to the initial state is better guaranteed, ensuring that the state switching of the manual unlocking mechanism 40 can be completed.

[0142] That is, the limiting portion 43 will be subjected to a force towards the bottom wall of the limiting groove 3212 during the sliding process of the limiting groove 3212, so that when the limiting portion 43 slides into the reset groove 3215, it can be blocked by the step surface 3218. The force towards the bottom wall of the limiting groove 3212 that the limiting portion 43 is subjected to can be realized by the assembly connection structure between the components, for example, by the assembly connection structure between the mounting bracket 321 and the manual unlocking mechanism 40.

[0143] Specifically, the manual unlocking mechanism 40 is elastic, such as Figure 11 As shown, the limiting portion 43 is elastic in the left-right direction, and the initial position of the limiting portion 43 is located at the center line Y of the limiting groove 3212, so that the limiting portion 43 can reset towards the center line Y after being subjected to a force. That is, when the manual unlocking mechanism 40 is in the initial state or the unlocked state, the limiting portion 43 is located on the center line Y, which can better balance the force and guarantee the stability of state maintenance.

[0144] Please refer toFigure 14 、 Figure 15 、 Figure 16 In another embodiment, the specific connection structure between the manual unlocking mechanism 40 and the mounting bracket 321 is that one end of the manual unlocking mechanism 40 is rotatably mounted on the mounting bracket 321, and the manual unlocking mechanism 40 switches between the initial state and the unlocking state by swinging. For example, the other end of the manual unlocking mechanism 40 can be connected with an external driving mechanism, and the swinging of the manual unlocking mechanism 40 is driven by the external driving mechanism, so that the clutch 323 is brought to different positions by swinging the manual unlocking mechanism 40 to different positions.

[0145] Please refer to Figure 8 In one embodiment, the clutch 323 includes a clutch body 3233 and a reset elastic member 3234. The clutch body 3233 is arranged corresponding to the output unit 33, and the reset elastic member 3234 is connected with the clutch body 3233, and the reset elastic member 3234 is used to provide a driving force to maintain the state of the clutch body 3233. Wherein, the elastic member refers to a component that can elastically deform after being stressed, and can restore the initial state when the stress is reduced or eliminated. Wherein, the reset elastic member 3234 used to provide a driving force to maintain the state of the clutch body 3233 refers to that the reset elastic member 3234 is used to provide a driving force to combine the clutch body 3233 with the output unit 33, so as to maintain the combined state of the clutch body 3233; or the reset elastic member 3234 is used to provide a driving force to separate the clutch body 3233 from the output unit 33, so as to maintain the separated state of the clutch body 3233. When the reset elastic member 3234 is used to provide a driving force to combine the clutch body 3233 with the output unit 33, the reset elastic member 3234 can make the clutch body 3233 more stably combined with the output unit 33, and in some embodiments, it can also make the manual unlocking mechanism 40 switch from the unlocking state to the initial state more simply and conveniently. When the reset elastic member 3234 is used to provide a driving force to separate the clutch body 3233 from the output unit 33, the reset elastic member 3234 can make the clutch body 3233 more stably separated from the output unit 33, which can ensure the reliability of the unlocking, and also make the manual operation more simple. That is, the reset elastic member 3234 is used to provide a force in one direction to the clutch body 3233, so that the clutch body 3233 can maintain a stable state without external force, which can ensure the stability of the state maintenance, and in some embodiments, it can also make the manual operation more simple.

[0146] For example, in one embodiment, when the limiting portion 43 slides into the reset slot 3215, the clutch body 3233 can be moved by the reset elastic member 3234, so that the clutch body 3233 can move the control portion 42, and then the limiting portion 43 slides into the first portion 3216. Specifically, in one embodiment, the reset elastic member 3234 can be a spring. The reset elastic member 3234 can be installed on the mounting bracket 321 or the output shaft of the transmission unit group 322.

[0147] Please refer to Figures 1 to 4 and Figure 12 . Meanwhile, in one embodiment, a tire assembly 1000 is also provided, which includes a tire shaft 300, a tire 200, and the lock assembly 100 according to any one of the above embodiments. The tire 200 is rotatably installed on the tire shaft 300, and the lock assembly 100 is installed on the tire shaft 300 and arranged in the tire 200. In the tire assembly 1000 provided by the present embodiment, the lock assembly 100 is installed by using the tire shaft 300, and the lock assembly 100 is arranged in the tire 200, so that the overall structure is more compact and small, and the space required by the overall structure is reduced.

[0148] Preferably, in one embodiment, the tire 200 includes a tire body 210, a shell 220, and an end cover 230. The shell 220 is connected to the tire body 210, and the end cover 230 is arranged at one end of the shell 220. The lock assembly 100 is arranged in the space surrounded by the tire body 210, the shell 220, and the end cover 230. Through this structure, the lock assembly 100 can be better protected.

[0149] Preferably, in an embodiment, the tire assembly 1000 further comprises a manual control mechanism 400 movably mounted on the end cover 230 and corresponding to the manual unlocking mechanism 40 in the lock assembly 100, the manual control mechanism 400 being used to drive the manual unlocking mechanism 40. Wherein, the manual control mechanism 400 is movably mounted on the end cover 230 means that the manual control mechanism 400 is mounted on the end cover 230 and the manual control mechanism 400 can move relative to the end cover 230, specifically, the manual control mechanism 400 can move along the axial direction of the tire shaft 300 relative to the end cover 230. Thus, the movement of the manual control mechanism 400 can correspondingly drive the manual unlocking mechanism 40 to switch the state of the manual unlocking mechanism 40. That is, in an embodiment, when the lock assembly 100 needs to be manually unlocked, the operator can apply force to the manual control mechanism 400, and then the manual control mechanism 400 moves to drive the manual unlocking mechanism 40, so that the manual unlocking mechanism 40 drives the clutch 323, so that the output unit 33 is separated from the clutch 323, and the manual unlocking of the lock assembly 100 is realized. Mounting the manual control mechanism 400 on the end cover 230 can make the overall structure more compact and simple, and also facilitate the operation of the manual control mechanism 400.

[0150] Preferably, in an embodiment, the manual control mechanism 400 comprises a driving member 410 and a control member 420. The driving member 410 is movably mounted on the end cover 230, and the control member 420 is located between the driving member 410 and the manual unlocking mechanism 40. The driving member 410 is used to drive the control member 420 to move to drive the manual unlocking mechanism 40 through the control member 420. That is, in an embodiment, when the manual control mechanism 400 is controlled, the operator directly applies force to the driving member 410, and then the driving member 410 drives the control member 420 to move, thereby driving the manual unlocking mechanism 40.

[0151] Please refer to Figures 2 to 4Preferably, in an embodiment, the driving member 410 is a driving button, and a driving member reset spring is further arranged between the driving member 410 and the end cover 230. That is, in this embodiment, the control movement of the driving member 410 can be realized by pressing the driving member 410. It can be understood that in the prior art, the control mechanism of the manual unlocking usually needs to be manually operated by the operator. Since the tire is located at the bottom of the vehicle, the operator needs to bend down to operate the control every time. In this embodiment, by setting the driving member 410 as a press type structure, the operator can kick the driving member 410 when operating, so as to realize the operation control of the driving member 410, and make the operation control more convenient and simple. When the manual unlocking mechanism 40 is switched to the initial state, the driving member reset spring can drive the reset. Specifically, in an embodiment, the driving member reset spring can be a spring.

[0152] Please refer to Figure 12 Preferably, in an embodiment, the specific connection structure of the driving member 410 can also be that the driving member 410 is threadedly connected with the end cover 230. Thus, in this embodiment, the operation control of the driving member 410 can be realized by screwing the driving member 410. It can be understood that since the driving member 410 is threadedly connected with the end cover 230, during the movement of the tire 200 after the vehicle lock assembly 100 is unlocked, the end cover 230 will rotate synchronously with the tire 200, at this time, the driving member 410 and the end cover 230 can exist relative rotation, and the driving member 410 exists the risk of falling off. The falling of the driving member 410 can be avoided by improving the cooperation structure between the manual unlocking mechanism 40 and the manual control mechanism 400. For example, in the embodiment as shown in Figure 14 When the driving member 410 is screwed to the outside of the mounting groove on the end cover 230, the manual unlocking mechanism 40 is in the unlocked state, the clutch 323 is separated from the output unit 33, at this time, since the driving member 410 is located outside the mounting groove on the end cover 230, the driving member 410 is easy to fall off from the end cover 230 during the movement of the tire 200; and in the embodiment as shown in Figure 15In the shown embodiment, when the driving member 410 is screwed into the inside of the mounting groove on the end cover 230, the driving member 410 presses down the control member 420 to unlock the manual unlocking mechanism 40, and the clutch 323 is separated from the output unit 33. At this time, because the driving member 410 is in the position inside the mounting groove on the end cover 230, the driving member 410 is limited from falling off the end cover 230 by the cooperation between the threads during the movement of the tire 200. That is, the matching relationship between the position state of the driving member 410 on the end cover 230 and the state of the manual unlocking mechanism 40 can be improved, and when the driving member 410 is screwed into the inside of the mounting groove on the end cover 230, the manual unlocking mechanism 40 is controlled to be in the unlocked state, so that the risk of the driving member 410 falling off during the movement of the tire 200 by manual pushing can be reduced.

[0153] It can be understood that the force exertion direction of the reset elastic member 3234 on the clutch 323 can be different in Figure 14 and Figure 15 , that is, the reset elastic member 3234 in one embodiment is used to maintain the state that the clutch 323 is separated from the output unit 33, and the reset elastic member 3234 in another embodiment is used to maintain the state that the clutch 323 is combined with the output unit 33.

[0154] Please refer to Figures 17 to 20 . Preferably, in one embodiment, the specific connection structure of the driving member 410 can also be that the driving member 410 is rotatably installed on the end cover 230 through the rotating shaft 430, and the setting direction of the rotating shaft 430 is perpendicular to the setting direction of the tire shaft 300. The driving member 410 has a first state and a second state after rotating around the rotating shaft 430. When the driving member 410 is converted from the first state to the second state, the driving member 410 abuts against and presses the control member 420 to drive the control member 420 to drive the manual unlocking mechanism 40 through the control member 420. That is, in this embodiment, the driving member 410 can adopt a wrench structure, and the operator can drive the control member 420 by turning the driving member 410. Specifically, in one embodiment, the driving member 410 includes a turning member 4100 and a pressing member 4200 connected with the turning member 4100, and the cam surface of the pressing member 4200 cooperates with the end surface of the control member 420. During the rotation of the driving member 410, the cam surface of the pressing member 4200 corresponds to and presses the control member 420, thereby driving the control member 420 to move.

[0155] Preferably, in an embodiment, the control member 420 is further provided with a control member reset elastic member. When the driving member 410 is in the first state, the control member reset elastic member drives the control member 420 to reset. Through the provision of the control member reset elastic member, the automatic reset of the control member 420 can be realized, and the operation is simplified. The control member reset elastic member can be mounted on the end cover 230 and sleeved on the outer periphery of the control member 420. Specifically, in an embodiment, the control member reset elastic member can adopt a spring.

[0156] Preferably, in an embodiment, the driving member 410 is further connected with a torsion spring 440, one end of the torsion spring 440 is connected with the end cover 230, and the other end is connected with the driving member 410. The torsion spring 440 is used to push the driving member 410 from the first state to the second state, and through the provision of the torsion spring 440, the difficulty of the operator to pull the driving member 410 can be further reduced.

[0157] Preferably, in an embodiment, the mounting bracket 321 for mounting the self-locking transmission mechanism 30 on the tire shaft 300 is provided with an anti-rotation structure. Specifically, the anti-rotation structure can be a square shaft, and the mounting hole on the tire shaft 300 for mounting the mounting bracket 321 is a square hole corresponding to the square shaft, so that through the cooperation between the square hole and the square shaft, the rotation of the mounting bracket 321 can be better prevented, and the reliability of the transmission can be better ensured.

[0158] At the same time, in an embodiment, a vehicle is also provided, which is applied with the vehicle lock assembly 100 in any of the above embodiments or applied with the tire assembly 1000 in any of the above embodiments. Specifically, in an embodiment, the vehicle can be a wheelchair, a walker for the elderly, a supermarket cart, etc.

[0159] The above only describes the embodiments of the present application, and it should be noted that for those skilled in the art, improvements can be made without departing from the inventive concept, and these all belong to the protection scope of the present application.
