Description

Technical Field

[0001] The present invention relates to vehicle locks, and particularly to a hub lock and a shared vehicle.

Background Art

[0002] To prevent vehicles such as bicycles, electric bicycles, and motorized bicycles from being stolen, people usually use vehicle locks to lock the vehicles. In daily life, the most common vehicle lock is a horseshoe lock. The lock body of the horseshoe lock is usually in a ring shape with an opening provided thereon. When locking the vehicle, inserting a metal rod into the opening of the lock body can prevent the rotation of the wheel hub, thus achieving the effect of locking the vehicle. Such a horseshoe lock is externally mounted on the vehicle body and is very easy to be violently damaged. For example, the metal rod can be cut off by tools to achieve violent unlocking. Therefore, the locking security of this kind of lock needs to be improved.

[0003] Another relatively common vehicle lock is a hub lock. The hub lock uses a locking pin to lock the rotation of the wheel hub to achieve the locking effect. Existing hub locks usually cannot effectively monitor the locked and unlocked states of the vehicle lock. For a shared vehicle system or an intelligent vehicle, it is necessary to monitor the state of the vehicle. Therefore, existing hub locks cannot meet the requirements.

[0004] In addition, existing vehicle locks cannot monitor the vehicle speed. And for shared vehicles, they are often parked outdoors, and there is a relatively high demand for waterproof performance. Therefore, existing vehicle locks still need to be improved to further meet the requirements of waterproofing and state monitoring.

Detailed Implementation Manner

[0027] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation to the present invention.

[0028] As Figures 1 to 3 shown, the hub lock of the present invention includes a hub housing 10, a lock core housing 20, a hub shaft 30, a control board 40, a drive motor 50, a transmission mechanism 60, a lock pin assembly 70, a first switch 81, a second switch 82, and a vehicle motion detection device. Among them, the hub housing 10 and the lock core housing 20 are sleeved on the hub shaft 30, the hub housing 10 can rotate relative to the hub shaft 30, and the lock core housing 20 is stationary relative to the hub shaft 30; the drive motor 50 is used to provide driving force, and the transmission mechanism 60 is arranged between the drive motor 50 and the lock pin assembly 70 for transmission; the lock pin assembly 70 is used to lock the hub housing 10 to achieve locking; the first switch 81 and the second switch 82 are connected to the control board 40, which are used to monitor the locking and unlocking states of the vehicle; the vehicle motion detection device is used to detect the motion state and driving speed of the vehicle.

[0029] As Figures 1 to 3 shown, the hub shaft 30 is used for fixedly connecting to a vehicle. When riding, the vehicle hub rotates while the hub shaft 30 remains stationary, and the vehicle hub rotates around the hub shaft 30 as the rotation center. To facilitate the connection of the hub shell 10 and the lock core shell 20, the hub shaft 30 is provided with a threaded portion 31, a round shaft portion 32, and an anti-rotation portion 33. The anti-rotation portion 33 is located in the middle of the hub shaft 30, which is used to connect the lock core shell 20 and prevent the lock core shell 20 from rotating circumferentially. The shape of the anti-rotation portion 33 can be set as needed, including but not limited to square, oval, irregular shape, etc. In this embodiment, the anti-rotation portion 33 is square. The round shaft portion 32 is located at both ends of the anti-rotation portion 33, which is used to movably sleeved on the hub shell 10 and the gear disk 62, so that the hub shell 10 and the gear disk 62 can rotate around it. The threaded portion 31 is located at both ends of the hub shaft 30, which is used for threadedly connecting nuts 95, thereby restricting the hub shell 10 between the nuts 95 to prevent the hub shell 10 from moving axially along the hub shaft 30.

[0030] As Figure 2 、 Figure 3 shown, to strengthen the waterproof structure, a waterproof wire groove 34 can be provided on the hub shaft 30. The waterproof wire groove 34 is formed by extending along the axial direction from one end of the hub shaft 30. The waterproof wire groove 34 extends to the anti-rotation portion 33, so that the waterproof wire 35 can extend into the lock core shell 20.

[0031] As Figure 1 、 Figure 2 、 Figure 3 shown, the hub shell 10 includes a hub shell main body 11 and a hub shell end cover 12, which are covered together to form a cavity that can accommodate the lock core shell 20.

[0032] As Figure 2As shown, the hub shell body 11 is cylindrical, and a plurality of card slots 111 are provided on its inner wall. The card slots 111 are used to interact with the lock pin assembly 70 to achieve locking. The card slots 111 are arranged along the axial direction of the hub shell body 11 and are evenly distributed on the inner wall of the hub shell body 11. In this embodiment, one end of the hub shell body 11 is open, and the open end is used for mating connection with the hub shell end cover 12. The other end of the hub shell body 11 is rotatably connected to the hub shaft 30. The hub shell body 11 is sleeved on the circular shaft portion 32 of the hub shaft 30 and can rotate around the circular shaft portion 32. The axis of the hub shell body 11 coincides with the axis of the hub shaft 30. To facilitate the rotation of the hub shell body 11 around the hub shaft 30, a first bearing 91 is provided between the hub shaft 30 and the hub shell body 11. The first bearing 91 can be a well-known rolling bearing or the like. The inner ring of the first bearing 91 is connected to the hub shaft 30, and the outer ring of the first bearing 91 is connected to the hub shell body 11.

[0033] As Figure 1 , Figure 2 shown, the hub shell end cover 12 covers the open end of the hub shell body 11 and is used to enclose the hub shell body 11 to enhance the waterproof performance. The shape of the hub shell end cover 12 matches the shape of the open end of the hub shell body 11, and it is fixedly connected to the hub shell body 11 by screws 96. The hub shell end cover 12 is sleeved on the circular shaft portion 32 of the hub shaft 30 and can rotate around the circular shaft portion 32. The axis of the hub shell end cover 12 coincides with the axis of the hub shaft 30. To facilitate the rotation of the hub shell end cover 12 around the hub shaft 30, a second bearing 92 is provided between the hub shaft 30 and the hub shell end cover 12. The second bearing 92 can be a well-known rolling bearing or the like. The inner ring of the second bearing 92 is connected to the hub shaft 30, and the outer ring of the second bearing 92 is connected to the hub shell end cover 12.

[0034] As Figure 2 shown, a relatively enclosed third installation cavity 13 is formed between the hub shell end cover 12 and the hub shell body 11, and this third installation cavity 13 is used to install the lock core housing 20.

[0035] As Figure 3As shown, the lock core housing 20 is fixedly sleeved on the hub shaft 30 and cannot move axially or rotate circumferentially along the hub shaft 30. In other words, when the vehicle is moving, the lock core housing 20 is stationary relative to the hub shaft 30. The lock core housing 20 is used to provide a carrier for the installation of the drive motor 50, the control board 40, the transmission mechanism 60 and the lock pin assembly 70, and is also used to enhance the waterproof performance, and its specific shape is not limited. In this embodiment, the lock core housing 20 includes a lock core housing main body 21, an installation cover 22 and a lock core housing cover plate 23 which are connected in an opposing manner. In other embodiments, the structure of the lock core housing 20 can also be set in other forms, which is subject to facilitating the installation of the drive motor 50, the control board 40, the transmission mechanism 60 and the lock pin assembly 70.

[0036] In this embodiment, as Figure 3 shown, the lock core housing main body 21 is in a cylindrical shape, and a circular installation hole 211 is provided on its circumferential wall, which is used for movably arranging the lock pin assembly 70. A partition portion 212 distributed radially is provided inside the lock core housing main body 21. The partition portion 212 divides the lock core housing main body 21 into two spaces, so as to facilitate the formation of two installation cavities by opposing connection with the installation cover 22 and the lock core housing cover plate 23. A first central shaft hole 213 is provided at the center of the lock core housing main body 21. The shape and size of the first central shaft hole 213 match the anti-rotation portion 33 of the hub shaft 30. The lock core housing main body 21 is sleeved on the anti-rotation portion 33 of the hub shaft 30 through its first central shaft hole 213.

[0037] As Figure 3 shown, the installation cover 22 is oppositely connected to one end of the lock core housing main body 21, and a first installation cavity is formed between it and the lock core housing main body 21. The first installation cavity is used for installing the drive motor 50 and the control board 40. The installation cover 22 is fixedly connected to the lock core housing main body 21 in a known manner, such as being fixed by screws 96. A second central shaft hole 221 is provided at the center of the installation cover 22. The shape of the second central shaft hole 221 matches the anti-rotation portion 33 or the circular shaft portion 32. In this embodiment, the second central shaft hole 221 is a circular hole, and its inner diameter is larger than the outer diameter of the circular shaft portion 32, and a gap is formed therebetween, so as to facilitate the installation of the shaft sleeve.

[0038] As Figure 3As shown, the lock core housing cover plate 23 is joined in alignment to the other end of the lock core housing main body 21 opposite to the mounting cover 22. A second mounting cavity is formed between the lock core housing cover plate 23 and the lock core housing main body 21. The second mounting cavity is used for installing the transmission mechanism 60, the first switch 81, and the second switch 82. The lock core housing cover plate 23 is fixedly connected to the lock core housing main body 21 in a known manner, such as being fixed by screws 96. A third central shaft hole 231 is provided at the center of the lock core housing cover plate 23, and the shape of the third central shaft hole 231 matches that of the anti-rotation portion 33 or the round shaft portion 32. In this embodiment, the third central shaft hole 231 is a square hole, which matches the anti-rotation portion 33.

[0039] As Figure 3 As shown, the lock core housing main body 21, the mounting cover 22, and the lock core housing cover plate 23 are joined in alignment to form the lock core housing 20, which is sleeved on the anti-rotation portion 33 of the hub shaft 30 and cannot rotate circumferentially. The external dimension of the lock core housing 20 is smaller than the internal dimension of the hub housing 10. Therefore, the lock core housing 20 does not affect the rotation of the hub housing 10.

[0040] As Figure 2 As shown, to limit the axial movement of the lock core housing 20, a shaft sleeve is provided between the lock core housing 20 and the hub housing 10 for abutment. Specifically, a first shaft sleeve 93 is provided between the lock core housing cover plate 23 and the first bearing 91, and a second shaft sleeve 94 is provided between the mounting cover 22 and the second bearing 92. The first shaft sleeve 93 is sleeved on the round shaft portion 32 of the hub shaft 30, one end of which abuts against the end face of the first bearing 91, and the other end abuts against the lock core housing cover plate 23. The second shaft sleeve 94 is sleeved on the round shaft portion 32 of the hub shaft 30, one end of the first shaft sleeve 93 abuts against the end face of the second bearing 92, and the other end is inserted into the gap between the mounting cover 22 and the hub shaft 30 and abuts against the end face of the lock core housing main body 21.

[0041] As Figure 2 As shown, through the first shaft sleeve 93 and the second shaft sleeve 94, the axial movement of the lock core housing 20 relative to the hub housing 10 can be restricted. Further, to limit the axial movement of the hub housing 10 along the hub shaft 30, a number of nuts 95 are provided outside both the first bearing 91 and the second bearing 92. The nuts 95 are threadedly connected to the threaded portion 31 of the hub shaft 30 and abut against the first bearing 91 and the second bearing 92, so that the hub housing 10 cannot move axially along the hub shaft 30. Since the lock core housing 20 is restricted by the shaft sleeve and cannot move axially relative to the hub housing 10, the lock core housing 20 also cannot move axially relative to the hub shaft 30.

[0042] The control board 40 is used for control. It can receive the signals of the first switch 81, the second switch 82, and the Hall switch to control the working state of the drive motor 50. As Figure 3 shown, the control board 40 is arranged in the first installation cavity and is fixed in a known manner. For example, it is fixed to the installation cover 22 by screws 96.

[0043] As Figure 3 shown, the drive motor 50 is used to provide power. It is arranged in the first installation cavity and is connected to the control board 40. The drive motor 50 can be a known micro motor. In this embodiment, the drive motor 50 is arranged vertically in the first installation cavity, and its output end passes through the partition part 212 and extends into the second installation cavity, so as to be connected to the transmission mechanism 60.

[0044] As Figure 3 shown, the transmission mechanism 60 is arranged in the second installation cavity and is connected to the drive motor 50 and the lock pin assembly 70. The transmission mechanism 60 includes an output gear 61 and a gear disk 62.

[0045] As Figure 3 shown, the output gear 61 can be a known external gear 6212, which is connected to the output end of the drive motor 50. The axial direction of the output gear 61 is parallel to the axial direction of the hub shaft 30.

[0046] As Figure 3 shown, the gear disk 62 meshes with the output gear 61 and can drive the lock pin assembly 70 to move. The gear disk 62 is provided with an integrally formed gear part 621 and an eccentric part 622.

[0047] As Figure 3 shown, the gear part 621 is in the shape of a round wheel, and a plurality of external teeth 6212 are provided on its outer wall to mesh with the output gear 61. A fourth central shaft hole 6211 is provided at the center of the gear part 621, which is sleeved on the round shaft part 32 of the hub shaft 30 and can rotate around the hub shaft 30.

[0048] As Figure 3 shown, the eccentric part 622 protrudes from one side of the gear part 621. An eccentric chute 6221 is provided on the eccentric part 622. The eccentric chute 6221 is a long groove or through hole. For the convenience of description, the two ends of the eccentric chute 6221 along the sliding direction are respectively called the first end 6222 and the second end 6223. As Figure 4 、 Figure 5As shown, the distance from the first end 6222 of the eccentric chute 6221 to the axis of the gear portion 621 is greater than the distance from the second end 6223 of the eccentric chute 6221 to the axis of the gear portion 621, thus having an eccentric effect. In this way, the eccentric portion 622 can drive the locking pin assembly 70 to move, causing the distance between the locking pin assembly 70 and the hub shaft 30 to change. The shape of the eccentric chute 6221 can be set as required. In this embodiment, the eccentric chute 6221 is arc-shaped, the distance from the first end 6222 to the axis of the gear portion 621 is the largest, the distance from the second end 6223 to the axis of the gear portion 621 is the smallest, and between the first end 6222 and the second end 6223, the distance from the axis of the gear portion 621 gradually decreases.

[0049] As Figure 3 , Figure 4 , Figure 5 shown, the eccentric chute 6221 is used to set the convex column portion 731 of the locking pin assembly 70, so that the movement of the gear disk 62 can drive the locking pin assembly 70 to move.

[0050] As Figure 3 shown, the locking pin assembly 70 includes a latch pin 71, an elastic member 72, and a collar 73.

[0051] As Figure 3 shown, the latch pin 71 is cylindrical, is provided on the lock core housing 20, and is perpendicular to the hub shaft 30. The latch pin 71 can move in the direction of the card slot 111 on the inner wall of the hub housing 10, so as to be inserted into or withdrawn from the card slot 111. When the latch pin 71 is inserted into the card slot 111 of the hub housing 10, the hub housing 10 cannot rotate relative to the hub shaft 30 to achieve the vehicle locking effect. When the latch pin 71 withdraws from the card slot 111 of the hub housing 10, the hub housing 10 loses the limiting effect and can rotate, thus achieving the unlocking effect. In this embodiment, the latch pin 71 is cylindrical, is provided at the mounting hole 211 of the lock core housing 20, and can move along the mounting hole 211. To prevent the latch pin 71 from being withdrawn from the mounting hole 211, a convex edge portion 711 is provided at one end of the latch pin 71 facing the hub shaft 30. The convex edge portion 711 protrudes from the side wall of the latch pin 71, making the end of the latch pin 71 unable to pass through the mounting hole 211.

[0052] As Figure 3 shown, the elastic member 72 is provided between the latch pin 71 and the lock core housing 20. One end of the elastic member 72 abuts against the inside of the latch pin 71, and the other end of the elastic member 72 abuts against the lock core housing main body 21. When the hub lock is in the unlocked state, the elastic member 72 is in a compressed state.

[0053] As Figure 3As shown, the collar 73 is movably sleeved on the latch pin 71 and is located inside the lock core housing 20. A convex column portion 731 integrally formed therewith is provided on the collar 73, and the convex column portion 731 is disposed in the eccentric chute 6221 and can interact with the eccentric portion 622.

[0054] As Figure 3 shown, the latch pin 71, the elastic member 72, and the collar 73 form the latch assembly 70 of this embodiment. The latch assembly 70 is linked with the transmission mechanism 60 through the convex column portion 731 on the collar 73. When the gear disc 62 rotates around the hub shaft 30, the gear disc 62 will drive the collar 73 to move through the convex column portion 731. Since a convex edge portion 711 is provided at the end of the latch pin 71, when the collar 73 moves toward the hub shaft 30, the collar 73 can press the convex edge portion 711 to drive the latch pin 71 to move synchronously toward the hub shaft 30; since the collar 73 is movably sleeved on the latch pin 71, when the collar 73 moves away from the hub shaft 30, the collar 73 will not drive the latch pin 71 to move synchronously away from the hub shaft 30; however, the elastic member 72 in the compressed state can push the latch pin 71 to move away from the hub shaft 30 by its elastic force so that the latch pin 71 is engaged in the card slot 111 of the hub housing 10. If the latch pin 71 is aligned with the card slot 111, the elastic force of the elastic member 72 can push the latch pin 71 into the card slot 111; if the latch pin 71 is not aligned with the card slot 111, the latch pin 71 abuts against the inner wall of the hub housing 10, and when the vehicle is pushed and the hub rotates, the latch pin 71 can be engaged in the card slot 111 under the action of the elastic member 72.

[0055] As Figure 3 、 Figure 4 、 Figure 5 shown, in order to monitor the unlocking and locking states of the hub lock, a first switch 81 and a second switch 82 are provided on both sides of the gear disc 62. The first switch 81 and the second switch 82 are respectively connected to the control board 40. Among them, the first switch 81 is used to detect the unlocking state of the hub lock, and the second switch 82 is used to detect the locking state of the hub lock.

[0056] As Figure 5 shown, the position of the first switch 81 satisfies the following condition: when the gear disc 62 rotates to a position where the second end 6223 of its eccentric chute 6221 faces the convex column portion 731, the gear disc 62 touches the first switch 81.

[0057] As Figure 4 shown, the position of the second switch 82 satisfies the following condition: when the gear disc 62 rotates to a position where the first end 6222 of its eccentric chute 6221 faces the convex column portion 731, the gear disc 62 touches the second switch 82.

[0058] As Figure 5 shown, when the gear disk 62 touches the first switch 81, the lug portion 731 of the locking pin assembly 70 is located at the second end 6223 of the eccentric chute 6221. At this time, the locking pin assembly 70 is closest to the hub shaft 30 and farthest from the hub housing 10. Therefore, the latch 71 cannot extend into the card slot 111. Thus, the wheel hub lock is in the unlocked state;

[0059] As Figure 4 shown, when the gear disk 62 touches the second switch 82, the lug portion 731 of the locking pin assembly 70 is located at the first end 6222 of the eccentric chute 6221. At this time, the locking pin assembly 70 is farthest from the hub shaft 30 and closest to the hub housing 10. At this time, the latch 71 can be engaged into the card slot 111. Thus, the wheel hub lock is in the locked state.

[0060] To detect the vehicle running state and running speed, a vehicle motion detection device is provided on the wheel hub lock. The vehicle motion detection device is connected to the control board 40. When the vehicle is in the running state, the vehicle motion detection device can detect the current running speed and can send a shutdown signal to the control board 40 when detecting that the vehicle is in the running state, so that the control board 40 can control the drive motor 50 to be in the power-off state, thereby avoiding an uncontrollable locking phenomenon of the drive motor 50 during the movement and avoiding potential safety hazards.

[0061] The vehicle motion detection device can select corresponding sensing detection devices as needed. In this embodiment, the vehicle motion detection device includes a Hall switch and a magnetic medium body 83.

[0062] The Hall switch (not shown in the figure) is provided on the lock core housing 20 and is connected to the control board 40. The magnetic medium body 83 is provided on the hub housing 10. In this embodiment, the magnetic medium body 83 is selected as a steel ball. In other embodiments, it can also be selected as a magnet, a ferromagnetic member, etc. The number of the magnetic medium bodies 83 can be set as needed. In this embodiment, as Figure 2As shown, six steel balls are evenly distributed on the hub shell end cover 12. The magnetic medium 83 can be fixed to the hub shell end cover 12 in a known manner. When the vehicle is in motion, the hub shell 10 rotates, and the magnetic medium 83 rotates around the hub axis 30 following the hub shell 10; while the Hall switch is provided on the lock core housing 20 and is stationary relative to the hub axis 30. Therefore, when the vehicle is in motion, the magnetic medium 83 rotates relative to the Hall switch, and the Hall switch can detect the magnetic force signal. Whether the vehicle is in motion can be determined by the generation of the magnetic force signal, and the vehicle's motion speed can be further calculated based on the intensity of the magnetic force signal. In addition, when it is detected by the Hall switch and the magnetic medium 83 that the vehicle is in a moving state, the Hall switch sends a shutdown signal to the control board 40, and the control board 40 cuts off the working circuit of the drive motor 50, putting the drive motor 50 in a power-off state, thus avoiding uncontrollable unlocking phenomena during the movement of the drive motor 50 and eliminating potential safety hazards.

[0063] To enhance the waterproof performance, the first switch 81, the second switch 82, and the drive motor 50 are all selected as waterproof components. In addition, a waterproof wire 35 is provided on the hub axis 30. The waterproof wire 35 is arranged in the waterproof wire groove 34, with one end extending into the lock core housing 20 and the other end extending outside the hub shell 10.

[0064] Thus, the hub lock of the present invention is formed: as Figure 2 , Figure 3 shown, the hub shell 10 is sleeved on the hub axis 30 and can rotate around the hub axis 30; the lock core housing 20 is arranged inside the hub shell 10 and is sleeved on the hub axis 30; the lock core housing 20 is stationary relative to the hub axis 30; a control board 40, a drive motor 50, a transmission mechanism 60, a lock pin assembly 70, a first switch 81, a second switch 82, and a vehicle motion detection device are provided inside the lock core housing 20. The drive motor 50, the first switch 81, the second switch 82, and the vehicle motion detection device are respectively electrically connected to the control board 40. After the first switch 81, the second switch 82, and the vehicle motion detection device detect corresponding signals, they can send signals to the control board 40 to control the working state of the drive motor 50; the drive motor 50 drives the lock pin assembly 70 to move through the transmission mechanism 60, so that the locking pin 71 of the lock pin assembly 70 engages with or disengages from the card slot 111 of the hub shell 10, thereby achieving the unlocking or locking effect. The first switch 81 can detect the unlocking state of the vehicle, the second switch 82 can detect the locking state of the vehicle, and the vehicle motion detection device can detect the vehicle's traveling speed and motion state.

[0065] The hub lock of the present invention is in the locked state by default (as Figure 4As shown), that is, the boss portion 731 of the locking pin assembly 70 corresponds to the first end 6222 of the eccentric slot 6221, and the bayonet 71 of the locking pin assembly 70 is snapped into the bayonet slot 111 of the hub shell 10.

[0066] The wheel hub lock unlocking principle of the present invention is as follows:

[0067] like Figure 4 , Figure 5 As shown, when the vehicle receives a code scanning unlocking or other unlocking signal, the driving motor 50 drives the output gear 61 to rotate. For the convenience of description and understanding, this embodiment is described based on the directions shown in the accompanying drawings. Therefore, the directions involved in this embodiment are not absolute directions, but are relative to the accompanying drawings. Figure 4 As shown, when the driving motor 50 drives the output gear 61 to rotate, the output gear 61 rotates counterclockwise. Since the gear plate 62 is meshed with the output gear 61, the gear plate 62 rotates clockwise, so that the eccentric slot 6221 moves relative to the boss portion 731 of the lock pin assembly 70. Since the distances from the first end 6222 and the second end 6223 of the eccentric slot 6221 to the hub shaft 30 are inconsistent, and the lock pin assembly 70 is movably located in the mounting hole 211, when the gear plate 62 rotates clockwise, the gear plate 62 drives the lock pin assembly 70 to move radially. Since the distance from the first end 6222 of the eccentric slot 6221 to the hub shaft 30 is greater than the distance from the second end 6223 to the hub shaft 30, when the gear plate 62 rotates clockwise, it drives the lock pin assembly 70 to move toward the direction close to the hub shaft 30, so that the bayonet 71 is away from the hub shell 10. When the gear plate 62 rotates clockwise until the second end 6223 thereof faces the boss portion 731, Figure 4 Exercise to Figure 5 In the unlocked state, the latch pin 71 completely withdraws from the slot 111 to achieve the unlocking effect. At this time, the gear plate 62 touches the first switch 81, and the first switch 81 sends an unlocking success signal to the control board 40. At this point, the control board 40 controls the drive motor 50 to stop and determines that the unlocking action is completed.

[0068] The locking principle of the wheel hub lock of the present invention is as follows:

[0069] like Figure 5 As shown, when the vehicle receives the lock signal, the drive motor 50 drives the output gear 61 to rotate clockwise. Since the gear plate 62 is meshed with the output gear 61, the gear plate 62 rotates counterclockwise. Since the distance from the second end 6223 of the eccentric slot 6221 to the hub axle 30 is smaller than the distance from the first end 6222 to the hub axle 30, when the gear plate 62 rotates counterclockwise, it drives the lock pin assembly 70 to move away from the hub axle 30;

[0070] If the latch 71 is facing the slot 111 at this time, the latch 71 will gradually be inserted into the slot 111; when the gear plate 62 rotates counterclockwise until the first end 6222 thereof is opposite to the protruding column portion 731, the Figure 5 Exercise to Figure 4 When in the locked state, the latch pin 71 will be completely inserted into the slot 111 to achieve the locking effect; at this time, the gear plate 62 will touch the second switch 82, and the second switch 82 will send a locking success signal to the control board 40. At this point, the control board 40 controls the drive motor 50 to stop and determines that the locking action is completed.

[0071] If the latch 71 is not facing the latch groove 111 when locked, the latch 71 will press against the inner wall of the hub shaft 30; however, since the collar 73 is movably mounted on the latch 71, when the gear plate 62 rotates counterclockwise, the collar 73 moves toward the hub shell 10 until the gear plate 62 rotates to touch the second switch 82 (such as Figure 4 As shown); when the second switch 82 is touched, the second switch 82 sends a lock success signal to the control board 40, and the control board 40 controls the drive motor 50 to stop, and determines that the lock action is completed. At this time, the bayonet 71 is not inserted into the slot 111, and it is not in a real lock state. However, as long as the vehicle moves, its slot 111 will rotate to a position directly opposite to the bayonet 71. At this time, the elastic member 72 in the compressed state will push the bayonet 71, so that the bayonet 71 is inserted into the slot 111, thereby achieving the lock anti-theft effect. Therefore, although the bayonet 71 is not really inserted into the slot 111 at the beginning, it can be truly locked once the vehicle rotates, so it also has the lock anti-theft effect.

[0072] In addition, the present invention provides a shared vehicle, which includes a vehicle body and the wheel hub lock as described above, wherein the vehicle body is provided with a rotatable wheel hub, and the wheel hub lock is provided at the wheel hub of the vehicle body and can lock the rotation of the wheel hub.

[0073] Although the present invention is disclosed through the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
