[0039] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0040] As Figures 1-6As shown, the embodiment provides a locking device, which comprises a frame body 1, a locking member 2, a locking elastic member 3, a conversion member 4, a trigger member 5, a blocking member 6 and a reset elastic member 7. The locking member 2 is slidably arranged on one side of the frame body 1 along a first direction. The locking member 2 comprises a locking state and an unlocking state. The locking elastic member 3 is configured to apply a biasing force to the locking member 2, so that the locking member 2 is in the locking state or the unlocking state. The conversion member 4 is rotatably arranged on the frame body 1. The conversion member 4 comprises a locking connecting portion 41, which is in sliding connection with the locking member 2. The trigger member 5 is slidably arranged on the frame body 1 along the first direction. One end of the blocking member 6 is hingedly connected with the trigger member 5, and the other end of the blocking member 6 is movably connected with the conversion member 4. The blocking member 6 comprises a locking position and an unlocking position. The reset elastic member 7 is configured to apply a biasing force to the trigger member 5, so that the trigger member 5 slides away from the blocking member 6 along the first direction, and the blocking member 6 switches between the locking position and the unlocking position. When the blocking member 6 is in the locking position, the blocking member 6 can move with the trigger member 5 and make the conversion member 4 rotate along a first circumferential direction, so that the locking member 2 switches to the locking state. When the blocking member 6 is in the unlocking position, the blocking member 6 can move with the trigger member 5 and make the conversion member 4 rotate along a second circumferential direction, so that the locking member 2 switches to the unlocking state. The first circumferential direction is opposite to the second circumferential direction.

[0041] When the locking member 2 is in the locking state, the biasing force applied by the locking elastic member 3 to the locking member 2 can keep the locking member 2 in the locking state. That is, only when the locking member 2 overcomes the biasing force under the action of an external force, the locking member 2 can be released from the locking state. When the locking member 2 is in the unlocking state, the biasing force applied by the locking elastic member 3 to the locking member 2 can keep the locking member 2 in the unlocking state. That is, only when the locking member 2 overcomes the biasing force under the action of an external force, the locking member 2 can be released from the unlocking state. Exemplarily, the locking elastic member 3 is an eccentric spring. Of course, the locking elastic member 3 can also adopt other structures in the prior art, which are not limited herein.

[0042] When the locking member 2 needs to switch from the unlocking state to the locking state, as shown, the trigger member 5 can be driven to slide along the first direction to the blocking member 6, so as to press the reset elastic member 7 and make the reset elastic member 7 elastically deform. At the same time, the trigger member 5 also drives the blocking member 6 in the locking position to move along the first direction synchronously, so that the blocking member 6 drives the conversion member 4 to rotate along the first circumferential direction, and then the conversion member 4 drives the locking member 2 to slide and extend along the first direction, so as to switch to the locking state. Figure 3 Figure 4 ​As shown, the driving mechanism stops acting, the pushing force of the driving mechanism on the trigger 5 disappears, the trigger 5 slides in the first direction away from the gear 6 under the elastic force of the reset spring 7, on one hand, the gear 6 switches to the unlocking gear, on the other hand, the driving mechanism resets to prepare for the unlocking of the locking member 2.

[0043] When the locking member 2 needs to switch from the locking state to the unlocking state, as shown in FIG. 2, the driving mechanism acts again, and drives the trigger 5 to slide in the first direction towards the gear 6, and further extrudes the reset spring 7 to make the reset spring 7 generate elastic deformation again; at the same time, the trigger 5 drives the gear 6 in the unlocking gear to move synchronously in the first direction, so that the gear 6 drives the conversion member 4 to rotate in the second circumferential direction, and further drives the locking member 2 to slide in the first direction and retract to switch to the unlocking state. Figure 5 Figure 6 As shown, the driving mechanism stops acting again, the pushing force of the driving mechanism on the trigger 5 disappears, the trigger 5 slides in the first direction away from the gear 6 under the elastic force of the reset spring 7, on one hand, the gear 6 switches to the locking gear, on the other hand, the driving mechanism resets again to prepare for the next locking of the locking member 2.

[0044] That is, after the locking member 2 switches from the unlocking state to the locking state each time, the trigger 5 slides in the first direction away from the gear 6 to reset, and at the same time, the gear 6 switches from the locking gear to the unlocking gear. When the locking member 2 needs to switch from the locking state to the unlocking state again, the trigger 5 only needs to slide in the first direction towards the gear 6, so that the gear 6 in the unlocking gear drives the conversion member 4 to rotate in the second circumferential direction, and further drives the locking member 2 to unlock.

[0045] After the locking member 2 switches from the locking state to the unlocking state each time, the trigger 5 slides in the first direction away from the gear 6 to reset, and at the same time, the gear 6 switches from the unlocking gear to the locking gear. When the locking member 2 needs to switch from the unlocking state to the locking state again, the trigger 5 only needs to slide in the first direction towards the gear 6, so that the gear 6 in the locking gear drives the conversion member 4 to rotate in the first circumferential direction, and further drives the locking member 2 to lock.

[0046] ​Compared with the prior art, the locking device of the embodiment only needs to be provided with one driving mechanism, and the driving mechanism only needs to provide driving force in a single direction (i.e. the direction from the trigger 5 to the blocking piece 6 along the first direction) to control the rotation of the conversion piece 4 along the first circumferential direction to make the locking piece 2 slide along the first direction and extend to lock, or to control the rotation of the conversion piece 4 along the second circumferential direction opposite to the first circumferential direction to make the locking piece 2 slide along the first direction and retract to unlock, which not only has a simple structure, but also has the advantages of small size and low cost.

[0047] Exemplarily, the reset elastic member 7 is a spring, such as a torsion spring. Of course, the reset elastic member 7 can also adopt other structures in the prior art, which are not limited herein.

[0048] Optionally, as shown in the figure, one of the conversion piece 4 and the blocking piece 6 is provided with a conversion sliding groove 42, and the other of the conversion piece 4 and the blocking piece 6 is provided with a blocking connecting part 61, which is slidably arranged in the conversion sliding groove 42. Figure 2

[0049] When the blocking connecting part 61 slides in the conversion sliding groove 42, it will abut against the inner wall of the conversion sliding groove 42, thereby pushing the conversion piece 4 to rotate. When the blocking connecting part 61 slides to the two ends of the conversion sliding groove 42, it can also limit the limit position of the rotation of the conversion piece 4. Such a design not only has good processability and is easy to produce, but also is beneficial to improve the movement fluency and connection stability of the conversion piece 4 and the blocking piece 6.

[0050] In the embodiment, the conversion sliding groove 42 is arranged on the conversion piece 4, and the blocking connecting part 61 is arranged on the blocking piece 6. Of course, in other embodiments, the conversion sliding groove 42 can also be arranged on the blocking piece 6, and the blocking connecting part 61 can be arranged on the conversion piece 4.

[0051] Further, the blocking connecting part 61 has a cylindrical structure, and the blocking connecting part 61 is fixedly arranged on the blocking piece 6, which not only has a simple structure and is easy to produce, but also can improve the movement fluency of the conversion piece 4 and the blocking piece 6, and reduce the contact area between the blocking connecting part 61 and the inner wall of the conversion sliding groove 42, thereby reducing the friction.

[0052] In other embodiments, the blocking connecting part 61 can also be arranged in other shapes, and the blocking connecting part 61 can also be rotatably arranged on the blocking piece 6, which are not limited herein.

[0053] Optionally, one of the locking piece 2 and the locking connecting part 41 is provided with a locking sliding groove 21, and the other of the locking piece 2 and the locking connecting part 41 is provided with a locking connecting structure, which is slidably arranged in the locking sliding groove 21.

[0054] ​When the locking connection structure slides in the locking slide groove 21, the locking connection structure can abut against the inner wall of the locking slide groove 21, and then push the locking piece 2 to move in the first direction. When the locking connection structure slides to the two ends of the locking slide groove 21, the locking connection structure can also limit the limit position of the locking piece 2 sliding in the first direction (including the position of the locking piece 2 in the locked state and the position of the locking piece 2 in the unlocked state). In this way, the process is good, easy to produce, and the movement fluency and connection stability of the conversion piece 4 and the locking piece 2 are improved.

[0055] In the embodiment, the locking slide groove 21 is arranged on the locking piece 2, and the locking connection structure is arranged on the locking connection portion 41. Of course, in other embodiments, the locking slide groove 21 can be arranged on the locking connection portion 41, and the locking connection structure can be arranged on the locking piece 2.

[0056] Further, the locking connection structure is a cylindrical structure, and the locking connection structure is fixedly arranged on the locking connection portion 41. The structure is simple, easy to produce, the movement fluency of the conversion piece 4 and the locking piece 2 is improved, and the contact area between the locking connection structure and the inner wall of the locking slide groove 21 is reduced, and the friction is reduced.

[0057] In other embodiments, the locking connection structure can also be arranged in other shapes, and the locking connection structure can also be rotatably arranged on the locking connection portion 41, which is not limited here.

[0058] Optionally, the conversion piece 4 further comprises a frame connection portion 43, and the frame connection portion 43 is in sliding connection with the frame body 1, so as to further support the conversion piece 4 and improve the stability of the rotation of the conversion piece 4.

[0059] Optionally, one of the frame body 1 and the frame connection portion 43 is provided with a frame slide groove 11, and the other of the frame body 1 and the frame connection portion 43 is provided with a frame connection structure, and the frame connection structure is slidably arranged in the frame slide groove 11.

[0060] When the frame connection structure slides in the frame slide groove 11, the frame connection structure can abut against the inner wall of the frame slide groove 11, so as to support the conversion piece 4 and not interfere with the rotation of the conversion piece 4. The structure is simple and easy to produce.

[0061] In the embodiment, the frame slide groove 11 is arranged on the frame body 1, and the frame connection structure is arranged on the frame connection portion 43. Of course, in other embodiments, the frame slide groove 11 can be arranged on the frame connection portion 43, and the frame connection structure can be arranged on the frame body 1.

[0062] Further, the frame connection structure is a cylindrical structure, and the frame connection structure is fixedly arranged on the frame connection portion 43. The structure is simple, easy to produce, the movement fluency of the conversion piece 4 is improved, and the contact area between the frame connection structure and the inner wall of the frame slide groove 11 is reduced, and the friction is reduced.

[0063] In other embodiments, the rack connecting structure can also be provided in other shapes, and the rack connecting structure can also be rotatably arranged in the rack connecting portion 43, which is not limited herein.

[0064] Specifically, the conversion sliding groove 42 is a first arc-shaped groove, the rack sliding groove 11 is a second arc-shaped groove, and the locking sliding groove 21 is a rectangular groove. Further, the center of the first arc-shaped groove and the conversion mounting portion 44 are located on the same side of the first arc-shaped groove, and the center of the second arc-shaped groove and the conversion mounting portion 44 are located on the same side of the second arc-shaped groove. Through the above arrangement, the smoothness of the movement of the gear 6, the conversion piece 4 and the locking piece 2 is improved, and the processing and manufacturing are facilitated.

[0065] Of course, in other embodiments, the conversion sliding groove 42, the rack sliding groove 11 and the locking sliding groove 21 can also be provided in other shapes, which are not limited herein.

[0066] Optionally, the conversion piece 4 further comprises a conversion mounting portion 44, the conversion mounting portion 44 is rotatably connected with the rack body 1, and the locking connecting portion 41, the rack connecting portion 43 and the conversion mounting portion 44 are arranged in a triangular shape, thereby improving the smoothness and stability of the movement of the conversion piece 4 and the gear 6.

[0067] Exemplarily, the conversion mounting portion 44 is rotatably connected with the rack body 1 through a bearing or other rotating support, thereby improving the smoothness of the rotation of the conversion piece 4.

[0068] Optionally, one of the trigger piece 5 and the gear 6 is provided with a hinge shaft 51, the other of the trigger piece 5 and the gear 6 is provided with a hinge hole 62, and the hinge shaft 51 is rotatably arranged in the hinge hole 62, which is simple in structure and facilitates the hinge connection of the trigger piece 5 and the gear 6.

[0069] In this embodiment, the hinge shaft 51 is arranged in the trigger piece 5, and the hinge hole 62 is arranged in the gear 6. Of course, in other embodiments, the hinge shaft 51 can also be arranged in the gear 6, and the hinge hole 62 can be arranged in the trigger piece 5.

[0070] Optionally, the rack body 1 is provided with a trigger sliding groove 12, and the hinge shaft 51 is slidably arranged in the trigger sliding groove 12 along a first direction, thereby supporting the trigger piece 5 and limiting the limit position of the trigger piece 5 along the first direction, which improves the smoothness and stability of the movement of the trigger piece 5.

[0071] In other embodiments, the rack body 1 can also be provided with the trigger sliding groove 12, and the trigger piece 5 can be provided with a trigger connecting portion, which is slidably arranged in the trigger sliding groove 12. Of course, the trigger piece 5 can also be provided with the trigger sliding groove 12, and the rack body 1 can be provided with the trigger connecting portion, which is slidably arranged in the trigger sliding groove 12.

[0072] Optionally, the hinge shaft 51 is provided with a limiting block 511 at one of the hinge holes 62, and the hinge shaft 51 is provided with a limiting groove at the other one of the hinge holes 62, the limiting block 511 is arranged in the limiting groove, so as to prevent the blocking piece 6 and the trigger piece 5 from moving relatively along the hinge shaft 51 in the axial direction.

[0073] In the embodiment, the limiting block 511 is arranged on the hinge shaft 51, for example, the outer circumferential surface of the hinge shaft 51 or the end of the hinge shaft 51, and the limiting groove is arranged on the inner circumferential surface of the hinge hole 62. In other embodiments, the limiting block 511 can also be arranged on the inner circumferential surface of the hinge hole 62, and the limiting groove can be arranged on the outer circumferential surface of the hinge shaft 51.

[0074] Optionally, the locking device further comprises a driving mechanism, and the driving mechanism comprises a rotary driving unit, an output shaft of the rotary driving unit is provided with a pushing part, and the pushing part is connected with the trigger piece 5 to drive the trigger piece 5 to slide in the first direction to the direction close to the blocking piece 6.

[0075] When the output shaft of the rotary driving unit rotates, the pushing part can push the trigger piece 5 to slide in the first direction to the direction close to the blocking piece 6. That is to say, the rotary driving unit only needs to provide a single direction torque to drive the trigger piece 5 to slide in the first direction to the direction close to the blocking piece 6, so as to drive the conversion piece 4 to rotate in the first circumferential direction through the blocking piece 6 in the locking position, and then make the locking piece 2 slide in the first direction and extend to lock, or drive the conversion piece 4 to rotate in the second circumferential direction opposite to the first circumferential direction through the blocking piece 6 in the unlocking position, so as to make the locking piece 2 slide in the first direction and retract to unlock. At the same time, the torque provided by the rotary driving unit to drive the trigger piece 5 to slide is beneficial to improve the control accuracy.

[0076] Optionally, the rotary driving unit comprises a rotary driving piece and a worm and gear assembly, the worm and gear assembly comprises a worm and a gear which are meshed with each other, a rotating shaft of the rotary driving piece is fixedly connected with the worm, and the pushing part is arranged on the gear. Illustratively, the rotary driving piece is a motor. The pushing part rotating with the gear pushes the trigger piece 5 to slide in the first direction to the direction close to the blocking piece 6, and at the same time, the worm and gear assembly can also play a role of speed reduction, so as to improve the control accuracy. Of course, in other embodiments, other transmission mechanisms in the prior art can also be used to replace the worm and gear assembly, which is not limited here.

[0077] Illustratively, the working principle of the locking device in the embodiment is as follows:

[0078] It should be noted that, as shown in Figures 3 to 5 In order to facilitate description, one end of the conversion sliding groove 42 close to the locking piece is recorded as a first end 421, and the other end of the conversion sliding groove 42 is recorded as a second end 422.

[0079] As shown in Figure 3As shown, when the shift connection portion 61 is located at the first end 421 of the conversion slot 42 , the shift member 6 is in the locking position, and the shift member 6 will not continue to rotate relative to the trigger member 5 .

[0080] When the locking member 2 needs to be switched from the unlocked state to the locked state, as shown in FIG. Figure 3 As shown, the trigger member 5 can be driven by the driving mechanism to slide along the first direction toward the direction close to the stop member 6, thereby squeezing the reset elastic member 7 to cause the reset elastic member 7 to produce elastic deformation; at the same time, the trigger member 5 will also drive the stop member 6 in the locking position to move synchronously along the first direction, thereby causing the stop member 6 to drive the conversion member 4 to rotate along the first circumferential direction, and the conversion member 4 drives the locking member 2 to slide and extend along the first direction to switch to the locked state. At this time, under the action of the locking elastic member 3, the locking member 2 remains in the locked state, and the conversion member 4 is also fixed. Then, as shown in FIG. Figure 4 As shown, the driving mechanism stops, and the trigger member 5 slides in the first direction away from the stop member 6 under the elastic force of the reset elastic member 7. At this time, the stop member 6 moves with the trigger member 5, and the stop connection portion 61 slides within the conversion slot toward the second end 422, switching the stop member 6 to the unlocking position. At the same time, the driving mechanism resets, preparing for unlocking the locking member 2.

[0081] like Figure 5 As shown, when the shift connection portion 61 is located at the second end 422 of the conversion slot 42 , the shift member 6 is in the unlocking position, and at this time the shift member 6 will not continue to rotate relative to the trigger member 5 .

[0082] When the locking member 2 needs to be switched from the locked state to the unlocked state, Figure 5 As shown, the driving mechanism is activated again and drives the trigger member 5 to slide again along the first direction toward the shift member 6, thereby squeezing the reset elastic member 7 again to cause the reset elastic member 7 to produce elastic deformation again; at the same time, the trigger member 5 drives the shift member 6 in the unlocked position to move synchronously along the first direction, so that the shift member 6 drives the conversion member 4 to rotate along the second circumferential direction, and the conversion member 4 drives the locking member 2 to slide and retract along the first direction to switch to the unlocked state. At this time, under the action of the locking elastic member 3, the locking member 2 remains in the unlocked state, and the conversion member 4 is also fixed. Then, as shown in FIG. Figure 6 As shown, the driving mechanism stops again, and the trigger member 5 slides in the first direction away from the stop member 6 under the elastic force of the reset elastic member 7. At this time, the stop member 6 moves with the trigger member 5, and the stop connection portion 61 slides within the conversion slot toward the first end 421, switching the stop member 6 to the locking position. At the same time, the driving mechanism resets again to prepare for the next locking of the locking member 2.
