[0038] Specifically, the rotating shaft 4 refers to a columnar component with a certain length, and the rotating shaft 4 can be rotatably set on the frame, and its function is to connect the handlebars and the front fork. The frame refers to the supporting part of the entire vehicle, and the rotating shaft 4 is rotatably connected to the frame through the shell. The shell 5 refers to the part of the frame where the rotating shaft 4 is installed, which can be cylindrical, block-shaped or other shapes and is set at the front end of the frame. The rotating shaft 4 is rotatably set in the shell 5, and the shell 5 can be connected to the frame of the entire shared vehicle.

[0039] The first connecting member 1 refers to a component with a certain volume. The shape of the first connecting member 1 can be annular, cylindrical, plate-shaped or block-shaped. The shape of the first connecting member 1 can also be a combination of multiple shapes. The second connecting member 2 refers to a component with a certain volume.

Both the first connecting member 1 and the second connecting member 2 can be sleeved on the outside of the rotating shaft 4, wherein the first connecting member 1 is sleeved on the outside of the rotating shaft 4 with a gap, and a small gap sleeve is adopted. On the basis of the gap sleeve, the first connecting member 1 can be relatively fixed with the rotating shaft 4 through the connecting column 8, for example, the connecting column 8 can penetrate the rotating shaft 4 along the radial direction of the rotating shaft 4, and one end or both ends of the connecting column 8 are protruding from the surface of the rotating shaft 4. A clamping structure that cooperates with the end of the connecting column 8 is also provided on the first connecting member 1, so that the first connecting member 1 can rotate with the rotating shaft 4. The first connecting member 1 can also achieve relative fixation between the first connecting member 1 and the rotating shaft 4 by providing a protruding structure on the surface of the rotating shaft 4 and providing a clamping structure that cooperates with the protruding structure on the first connecting member 1. The first connecting member 1 can also achieve relative fixation between the first connecting member 1 and the rotating shaft 4 by other structures, which will not be described here. The inner wall of the second connecting member 2 can be connected with the outer wall of the rotating shaft 4 by clearance fit, so that the second connecting member 2 has the freedom to rotate around the axis of the rotating shaft 4 relative to the rotating shaft 4, and the second connecting member 2 can also slide along the axis direction of the rotating shaft 4.

[0040] The first action part 11 refers to a structure provided on the first connecting member 1, and the first action part 11 may be a convex structure or a groove structure, etc. The second action part 21 refers to a structure provided on the second connecting member 2, and the second action part 21 may also be a convex structure or a groove structure, etc. When the first action part 11 is a groove structure, the second action part 21 may be a convex structure, and at this time, the convex structure extends into the groove structure, and the outer wall of the convex structure and the inner wall of the groove structure abut against each other, so that the first connecting member 1 and the first connecting member 1 can be kept fixed. In addition, the first action part 11 may also adopt a convex structure, and at this time, the second action part 21 may adopt a groove structure. Its working principle is the same as when the first action part 11 adopts a groove and the second action part 21 is a convex structure. Please refer to the above content and will not be repeated here.

[0041] The slip structure 12 refers to a structure for enabling the first acting part 11 and the second acting part 21 to be disengaged. The slip structure 12 may be a guide surface structure, or a notch structure. The slip structure 12 is arranged on the first acting part 11 and / or the second acting part 21, including at least the following situations: the first situation is that the slip structure 12 is arranged on the first acting part 11; the second situation is that the slip structure 12 is arranged on the second acting part 21; the third situation is that a part of the slip structure 12 is arranged on the first acting part 11, and the other part is arranged on the second acting part 21. The above-mentioned preset threshold value refers to the friction value between the second acting part 21 and the slip structure 12 in the first situation, the friction value between the first acting part 11 and the slip structure 12 in the second situation, and the friction value between the two parts of the slip structure 12 arranged on the first acting part 11 and the second acting part 21 in the third situation.

[0042] The slip mechanism provided by the embodiment of the utility model is provided by sleeve-mounting the first connecting member 1 on the outside of the rotating shaft 4 and movably setting the second connecting member 2. Meanwhile, the first connecting member 1 has a first acting portion 11, and the second connecting member 2 has a second acting portion 21, the second acting portion 21 is used to interact with the first acting portion 11 so that the first connecting member 1 and the second connecting member 2 remain fixed, and the first acting portion 11 and / or the second acting portion 21 are provided with a slip structure 12, the slip structure 12 is used to disengage the first acting portion 11 from the second acting portion 21 when the first connecting member 1 is subjected to an external force exceeding a preset threshold, so that the first connecting member 1 and the second connecting member 2 can move relative to each other. Compared with the locking device in the prior art, when the rotating shaft 4 is locked, the second connecting member 2 and the housing 5 can be fixed by the switch lock mechanism 3, at which time the first connecting member 1 and the second connecting member 2 remain relatively fixed under the action of the first acting portion 11 and the second acting portion 21, so that the rotating shaft 4 and the housing 5 remain relatively fixed to achieve the locking of the handlebar. However, when the handlebar is forcibly twisted, the rotating shaft 4 and the first connecting member 1 will be subjected to a large impact force. At this time, the first connecting member 1 and the second connecting member 2 can move relative to each other to cause the rotating shaft 4 to slip, thereby avoiding the impact force from being transmitted to the contact part between the switch lock mechanism 3 and the second connecting member 2, thereby avoiding damage to the internal structure of the locking device.

[0043] In one embodiment, see Figure 2 , the second connecting member 2 also has a degree of freedom along the axial direction of the rotating shaft 4 relative to the rotating shaft 4, and the sliding mechanism also includes a first elastic member 6. The first elastic member 6 is located on the side of the second connecting member 2 away from the first connecting member 1, and is used to be sleeved on the outside of the rotating shaft 4. The first elastic member 6 is also used to apply a force toward the first connecting member 1 to the second connecting member 2 so that the second connecting member 2 abuts against the first connecting member 1. Specifically, the first elastic member 6 refers to an elastic component with a certain length, and the first elastic member 6 can be a spring, a rubber member, or a spring. The first elastic member 6 is provided on the side of the second connecting member 2 away from the first connecting member 1, and the second connecting member 2 also has a degree of freedom along the axial direction of the rotating shaft 4 relative to the rotating shaft 4. The first elastic member 6 can be used to apply a force toward the first connecting member 1 to the second connecting member 2, so that the cooperation between the first action portion 11 and the second action portion 21 is more stable. At the same time, when the rotating shaft 4 and the first connecting member 1 are subjected to a large impact force, the first elastic member 6 can shrink, so that the second connecting member 2 moves away from the first connecting member 1, so that the first acting part 11 and the second acting part 21 can be separated more conveniently, making the use of the entire vehicle locking device safer.

[0044] In an alternative embodiment, see Figure 2 The first elastic member 6 includes a spring or a rubber sleeve, and the first elastic member 6 is sleeved on the outside of the rotating shaft 4, so that the installation of the first elastic member 6 is more stable.

[0045] In one embodiment, see Figures 3 to 5 The first action portion 11 includes a receiving groove 111 disposed on the side of the first connector 1 facing the second connector 2, and the second action portion 21 includes a limiting protrusion 211 disposed on the side of the second connector 2 facing the first connector 1. The limiting protrusion 211 is used to be plugged and matched with the receiving groove 111 to keep the first connector 1 and the second connector 2 fixed, and at least part of the slip structure 12 is disposed on the side wall of the receiving groove 111. Specifically, the receiving groove 111 refers to a groove structure with a certain depth, and the limiting protrusion 211 refers to a protrusion structure with a certain height. By providing an accommodating groove 111 on the side of the first connecting member 1 close to the second connecting member 2 and a limiting protrusion 211 on the side of the second connecting member 2 close to the first connecting member 1, the limiting protrusion 211 can be extended into the accommodating groove 111 when the first connecting member 1 and the second connecting member 2 are close to each other, and the first connecting member 1 and the second connecting member 2 can be kept fixed by the mutual abutment between the outer wall of the limiting protrusion 211 and the inner wall of the accommodating groove 111, and when the first connecting member 1 is subjected to excessive external force, the limiting protrusion 211 can be disengaged from the accommodating groove 111 through the sliding structure 12 provided on the side wall of the accommodating groove 111, so that the first connecting member 1 and the second connecting member 2 can move relative to each other. The first action portion 11 and the second action portion 21 respectively adopt the method of accommodating the groove 111 and the limiting protrusion 211, which can make the first connecting member 1 and the second connecting member 2 more stable when not impacted by external force, and more smooth and convenient to disengage when impacted by external force, and can also make the overall structure of the first connecting member 1 and the second connecting member 2 simpler.

[0046] Also, see Figure 4 and Figure 5 The number of the accommodating grooves 111 can be multiple, and the multiple accommodating grooves 111 can be arranged at intervals around the axis of the rotating shaft 4, and the number of the corresponding limiting protrusions 211 is also multiple, and the number and position of the limiting protrusions 211 and the accommodating grooves 111 match each other. By providing multiple accommodating grooves 111 and limiting protrusions 211, the first connecting member 1 can be kept fixed with the first connecting member 1, so that the force between the first connecting member 1 and the first connecting member 1 is more even and balanced.

[0047] In one embodiment, see Figure 4The slip structure 12 includes a first guiding bevel 121 provided on the side wall of the accommodating groove 111, and the first guiding bevel 121 is used to guide the limiting protrusion 211 to slide out of the accommodating groove 111 when the first connecting member 1 is subjected to an external force exceeding a preset threshold. Specifically, the first guiding bevel 121 refers to a guiding surface structure of the surface of the first connecting member 1 connected to the bottom surface of the accommodating groove 111. The first guiding bevel 121 may be an inclined plane, or an inclined arc surface. By providing the first guiding bevel 121 on the side of the accommodating groove 111, when the rotating shaft 4 is forcibly twisted and the first connecting member 1 is subjected to a large impact, the limiting protrusion 211 can be conveniently detached from the accommodating groove 111 through the first guiding bevel 121, making it easier for the limiting protrusion 211 to disengage from the accommodating groove 111.

[0048] See also Figure 4 The first guiding inclined surface 121 can be arranged on both sides of the accommodating groove 111 in the rotation direction of the rotating shaft 4, or the first guiding inclined surface 121 can be arranged on one side of the accommodating groove 111 in the rotation direction of the rotating shaft 4. When the first guiding inclined surface 121 is arranged on one side of the accommodating groove 111, the limiting protrusion 211 can be separated from the accommodating groove 111 from one side, and the handlebar can be twisted in one direction. When the first guiding inclined surface 121 is arranged on both sides of the accommodating groove 111, the limiting protrusion 211 can be separated from the accommodating groove 111 from both sides, and the handlebar can be twisted in both directions.

[0049] In one embodiment, see Figure 5 The slip structure 12 also includes a second guiding slope 212, which is arranged on the side of the limiting protrusion 211 facing the first guiding slope 121, and the second guiding slope 212 is used to slide with the first guiding slope 121. Specifically, the second guiding slope 212 refers to a guiding surface structure used to connect the top surface of the limiting protrusion 211 and the surface of the second connecting member 2. The second guiding slope 212 can be an inclined plane, or an inclined arc surface. The second guiding slope 212 is provided to slide with the first guiding slope 121 at the same time, which can make it easier for the limiting protrusion 211 to escape from the accommodating groove 111, thereby making the sliding mechanism safer to use.

[0050] In one embodiment, see Figure 2The sliding mechanism further includes a support structure 7, which is located on the side of the second connecting member 2 away from the first connecting member 1 and is spaced apart from the second connecting member 2. The support structure is used to be fixed to the rotating shaft 4, and one end of the first elastic member 6 abuts against the support structure 7, and the other end of the first elastic member 6 abuts against the second connecting member 2. Specifically, the support structure 7 refers to a component with a certain volume, and the support structure 7 can be a support frame, a support cylinder or a protruding structure. By arranging the support structure 7 on the rotating shaft 4, and abutting one end of the first elastic member 6 against the support structure 7 and the other end against the second connecting member 2, it is more convenient for the first elastic member 6 to push the second connecting member 2.

[0051] In an alternative embodiment, see Figure 2 The support structure 7 includes a support sleeve 71 sleeved on the outside of the rotating shaft 4, and an abutment member 72 extending in the radial direction of the rotating shaft 4 is also provided on the support sleeve 71. The abutment member 72 and the second connecting member 2 are spaced apart along the axial direction of the rotating shaft 4. The abutment member 72 can increase the area of ​​the entire support structure 7 in the radial direction of the rotating shaft 4 by setting the abutment member 72, providing a larger contact area for the abutment of the first elastic member 6, and the abutment member 72 is connected to the rotating shaft 4 through the support sleeve 71, so that the abutment member can be fixed more firmly and the installation of the entire support structure 7 can be more stable.

[0052] In one embodiment, see Figure 2 and Figure 3 The sliding mechanism also includes a connecting column 8, which is used to be fixed on the rotating shaft 4 and plugged with the first connecting member 1 to prevent the first connecting member 1 from rotating relative to the rotating shaft 4, and the connecting column 8 is also used to prevent the first connecting member 1 from moving along the axial direction of the rotating shaft 4, so that the first connecting member 1 and the second connecting member 2 are kept in contact with each other under the action of the first elastic member 6. Specifically, the connecting column 8 refers to a component with a certain length, and the connecting column 8 can be arranged along the radial direction of the rotating shaft 4 to penetrate the entire rotating shaft 4, so that at least one end of the connecting column 8 protrudes from the surface of the rotating shaft 4, and a limiting structure for accommodating the connecting column 8 can also be arranged on the first connecting member 1, and the end of the connecting column 8 extends into the limiting structure, so as to prevent the first connecting member 1 from rotating relative to the rotating shaft 4, and at the same time, it is also used to prevent the first connecting member 1 from moving along the axial direction of the rotating shaft 4, so that the first connecting member 1 and the second connecting member 2 are kept in contact with each other under the action of the first elastic member 6, so that the installation of the first connecting member 1 is more stable and firm, and the use of the sliding mechanism is more stable and reliable.

Specifically, the switch lock mechanism 3 refers to a mechanical device for fixing or keeping a certain component in a specific position to prevent it from moving when it is not needed. The switch lock mechanism 3 is used to lock the second connecting member 2 with the housing 5, thereby achieving the locking of the entire rotating shaft 4. It can be understood that the beneficial effects of the above-mentioned second aspect can be referred to the relevant description in the above-mentioned first aspect, and will not be repeated here.

The driving component 34 can be an electric push rod, a cam 342 structure or a linear motor, etc. The main housing 31 is fixed on the housing 5, and a movable locking member 32 is movably provided on the main housing 31. When the rotating shaft 4 needs to be locked, the movable locking member 32 can contact the second connecting member 2 under the action of the second elastic member 33 to lock the second connecting member 2, so that the second connecting member 2 cannot rotate, thereby locking the rotating shaft 4. When it is necessary to unlock, the movable locking member 32 is pushed away from the second connecting member 2 by the driving component 34, so that the movable locking member 32 is separated from the second connecting member 2. At this time, the second connecting member 2 can rotate with the rotating shaft 4, so that the rotating shaft 4 is in an unlocked state that can rotate freely. The switch lock mechanism 3 has a simple overall structure, which can save installation space, and the simple operation makes the locking of the rotating shaft 4 faster and more convenient.

[0055] In one embodiment, see Figure 7 , the side of the movable locking member 32 close to the second connecting member 2 is provided with a first locking portion 35, and the second connecting member 2 is provided with a second locking portion 22, and the first locking portion 35 cooperates with the second locking portion 22 to lock the second connecting member 2.

When the first locking portion 35 is a slot structure, the second locking portion 22 can be a convex structure that cooperates with the slot structure, and when the first locking portion 35 is a convex structure, the second locking portion 22 can be a slot structure that cooperates with the slot structure. When the movable locking member 32 is close to the second connecting member 2. The convex structure can be inserted into the slot structure, so that the position between the second connecting member 2 and the movable locking member 32 remains relatively fixed, making the locking of the second connecting member 2 more stable and more convenient and quick.

[0056] In an alternative embodiment, see Figure 7 The first locking portion 35 includes a locking slot 351, and the second locking portion 22 includes a locking rib 221. Specifically, the locking slot 351 refers to a slot structure with a certain depth, and the locking rib 221 refers to a protruding structure with a certain height. When the second connecting member 2 is locked, the movable locking member 32 moves toward the direction close to the second connecting member 2, so that the locking rib 221 can be inserted into the locking slot 351, so that the position between the second connecting member 2 and the movable locking member 32 remains relatively fixed, making the structure of the movable locking member 32 and the second connecting member 2 simpler.

[0057] In one embodiment, see Figure 7 , one end of the movable locking member 32 is hinged to the main housing 31 and the other end is a free end, and the driving assembly 34 contacts the free end. Specifically, by hingedly connecting one end of the movable locking member 32 to the main housing 31 and the other end being a free end, the movable locking member 32 can swing in the main housing 31, which can reduce the space occupied by the movable locking member 32 while ensuring the movement of the movable locking member 32, and also keep the movement of the movable locking member 32 stable, thereby improving the overall stability of the switch lock mechanism 3 and making the use of the switch lock mechanism 3 safer and more reliable.

[0059] In an optional embodiment, the main shell 31 may include an upper shell and a lower shell that are interlocked, wherein the movable locking member 32 can be hinged on the lower shell, and a support member for maintaining the stable movement of the movable locking member 32 is also provided on the upper shell, which can contact the movable locking member 32 after the upper shell and the lower shell are interlocked, thereby maintaining the stable movement of the movable locking member 32.

[0060] In one embodiment, see Figure 7 The driving assembly 34 includes a cam 342 and a power unit 341. The cam 342 is rotatably arranged on the main housing 31.

Specifically, the cam 342 refers to a component whose edge and the rotation axis are changed. Through the swing or rotation of the cam 342, the follower can provide a preset movement. The power unit 341 refers to a component that can output torque. The power unit 341 can be a motor, etc. By making the circumference of the cam 342 movably abut against the free end of the movable locking member 32, and then the power unit 341 drives the cam 342 to rotate. When the cam 342 rotates, the movable locking member 32 will be pushed away from the second connecting member 2 as the shape of the cam 342 changes. When the cam 342 rotates to stop acting on the movable locking member 32, the movable locking member 32 will move toward the direction close to the second connecting member 2 under the action of the second elastic member 33. By using the cam 342 to cooperate with the power unit 341, the use of the driving component 34 is made more convenient.

[0061] In an alternative embodiment, see Figure 7 , the power unit 341 can be a motor, and the switch lock mechanism 3 can also include a control unit, which is electrically connected to the motor. In the locked state, the rotating shaft 4 is locked. When the unlock command is transmitted to the control unit by scanning the code from the outside, the control unit will control the motor to rotate, so that the cam 342 starts to rotate. When the protruding end of the cam 342 gradually approaches the free end of the movable locking member 32 to abut against it, the movable locking member 32 moves away from the second connecting member 2, so that the locking rib 221 is separated from the locking slot 351, and the unlock state is achieved. In the unlocked state, the rotating shaft 4 is in an unlocked state. When the lock command is transmitted to the control unit by scanning the code from the outside, the control unit drives the motor to rotate, so that the cam 342 starts to rotate. When the protruding end of the cam 342 gradually moves away from the free end of the movable locking member 32, the movable locking member 32 will gradually approach the second connecting member 2 under the action of the second elastic member 33, so that the locking rib 221 is inserted into the locking slot 351, and the position of the second connecting member 2 is locked, and the locked state is achieved.

[0062] In another alternative embodiment, see Figure 7, a transmission unit is provided between the power unit 341 and the cam 342. Specifically, the transmission unit refers to a component responsible for transmitting force and motion, and the transmission unit may be a gear transmission, a chain transmission, or a belt transmission, etc. By providing a transmission unit between the power unit 341 and the cam 342, the speed ratio of the power unit 341 and the cam 342 can be adjusted, and the output torque of the power unit 341 can be increased; and the power unit 341 does not need to be directly connected to the cam 342, so that the setting of the power unit 341 is more flexible.
