[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] like Figure 1-6As shown, this embodiment provides a locking device, including a frame 1, a locking member 2, a locking elastic member 3, a conversion member 4, a trigger member 5, a stop member 6 and a reset elastic member 7. The locking member 2 is slidably arranged on one side of the frame 1 along a first direction; the locking member 2 includes a locked state and an unlocked state, and 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 a locked state or an unlocked state; the conversion member 4 is rotatably arranged on the frame 1, and the conversion member 4 includes a locking connection portion 41, and the locking connection portion 41 is slidably connected to the locking member 2; the trigger member 5 is slidably arranged on the frame 1 along the first direction, one end of the stop member 6 is hinged to the trigger member 5, and the stop member 6 The other end is movably connected with the conversion member 4, and the shifting member 6 includes 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 along a first direction away from the shifting member 6 and switches the shifting member 6 between the locking position and the unlocking position; when the shifting member 6 is in the locking position, the shifting member 6 can move with the trigger member 5 and rotate the conversion member 4 along a first circumferential direction so that the locking member 2 switches to the locking state; when the shifting member 6 is in the unlocking position, the shifting member 6 can move with the trigger member 5 and rotate the conversion member 4 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 locked state, the biasing force applied by the locking elastic member 3 to the locking member 2 will keep the locking member 2 in the locked state, that is, only when the locking member 2 overcomes the biasing force under the action of an external force, the locking member 2 will be released from the locked state; when the locking member 2 is in the unlocked state, the biasing force applied by the locking elastic member 3 to the locking member 2 will keep the locking member 2 in the unlocked state, that is, only when the locking member 2 overcomes the biasing force under the action of an external force, the locking member 2 will be released from the unlocked 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 here.

[0042] When the locking member 2 needs to be switched from the unlocked state to the locked state, 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, so that the stop 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 to switch to the locked state. At this time, Figure 4As shown, the driving mechanism stops moving, and the thrust exerted by the driving mechanism on the trigger member 5 disappears. The trigger member 5 will slide along the first direction away from the shift member 6 under the elastic force of the reset elastic member 7, which on the one hand switches the shift member 6 to the unlocking position, and on the other hand resets the driving mechanism to prepare for unlocking the locking member 2.

[0043] When the locking member 2 needs to be switched from the locked state to the unlocked state, such as 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 direction close to the stop member 6, and then squeezes the reset elastic member 7 again, so that the reset elastic member 7 produces elastic deformation again; at the same time, the trigger member 5 drives the stop member 6 in the unlocking position to move synchronously along the first direction, so that the stop member 6 drives the conversion member 4 to rotate along the second circumferential direction, and then the conversion member 4 drives the locking member 2 to slide and retract along the first direction to switch to the unlocking state. At this time, Figure 6 As shown, the driving mechanism stops moving again, and the thrust of the driving mechanism on the trigger member 5 disappears. The trigger member 5 will slide along the first direction away from the shift member 6 under the elastic force of the reset elastic member 7, which on the one hand switches the shift member 6 to the locking position, and on the other hand resets the driving mechanism again to prepare for the next locking of the locking member 2.

[0044] That is to say, each time the locking member 2 switches from the unlocked state to the locked state, the trigger member 5 will slide along the first direction away from the shift member 6 to reset, and at the same time, the shift member 6 will switch from the locked position to the unlocked position. When the locking member 2 needs to switch from the locked state to the unlocked state again, the trigger member 5 only needs to slide along the first direction toward the shift member 6 again, and the shift member 6 in the unlocked position can drive the conversion member 4 to rotate along the second circumferential direction, thereby driving the locking member 2 to be unlocked.

[0045] Each time the locking member 2 switches from the locked state to the unlocked state, the trigger member 5 will slide along the first direction away from the stop member 6 to reset, and at the same time, the stop member 6 will switch from the unlocked position to the locked position. When the locking member 2 needs to switch from the unlocked state to the locked state again, the trigger member 5 only needs to slide along the first direction toward the stop member 6 again, and the stop member 6 in the locked position can drive the conversion member 4 to rotate along the first circumferential direction, thereby driving the locking member 2 to be locked.

[0046] Compared with the prior art, the locking device of this embodiment only needs to set up one driving mechanism, and the driving mechanism only needs to provide a driving force in a single direction (i.e., along the first direction from the trigger member 5 to the shift member 6), so as to control the conversion member 4 to rotate along the first circumferential direction so that the locking member 2 slides along the first direction and extends out to lock, or control the conversion member 4 to rotate along the second circumferential direction opposite to the first circumferential direction so that the locking member 2 slides along the first direction and retracts to unlock. It not only has a simple structure, but also has the advantages of small size and low cost.

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

[0048] Alternatively, if Figure 2 As shown, one of the conversion member 4 and the shifting member 6 is provided with a conversion sliding groove 42 , and the other of the conversion member 4 and the shifting member 6 is provided with a shifting connecting portion 61 , and the shifting connecting portion 61 is slidably disposed in the conversion sliding groove 42 .

[0049] When the gear connection part 61 slides in the conversion slot 42, it will abut against the inner wall of the conversion slot 42, thereby pushing the conversion member 4 to rotate; when the gear connection part 61 slides to the two ends of the conversion slot 42, it can also limit the extreme position of the rotation of the conversion member 4. Such a setting not only has good processability and is easy to produce, but also is conducive to improving the movement smoothness and connection stability of the conversion member 4 and the gear member 6.

[0050] In this embodiment, the conversion chute 42 is provided on the conversion member 4, and the shift connection portion 61 is provided on the shift member 6. Of course, in other embodiments, the conversion chute 42 can also be provided on the shift member 6, and the shift connection portion 61 can also be provided on the conversion member 4.

[0051] Furthermore, the gear connection part 61 is a cylindrical structure, and the gear connection part 61 is fixed to the gear member 6, which not only has a simple structure and is easy to manufacture, but also can improve the movement smoothness of the conversion member 4 and the gear member 6, and reduce the contact area between the gear connection part 61 and the inner wall of the conversion slot 42, thereby reducing friction.

[0052] In other embodiments, the shift connection portion 61 may be configured to have other shapes, and the shift connection portion 61 may be rotatably disposed on the shift member 6 , which is not limited here.

[0053] Optionally, one of the locking member 2 and the locking connection portion 41 is provided with a locking groove 21 , and the other of the locking member 2 and the locking connection portion 41 is provided with a locking connection structure, and the locking connection structure can be slidably disposed in the locking groove 21 .

[0054] When the locking connection structure slides in the locking groove 21, it will abut against the inner wall of the locking groove 21, thereby pushing the locking member 2 to move along the first direction; when the locking connection structure slides to the two ends of the locking groove 21, it can also limit the extreme position of the sliding of the locking member 2 along the first direction (including the position when the locking member 2 is in a locked state and the position when the locking member 2 is in an unlocked state). Such a setting not only has good processability and is easy to produce, but also is conducive to improving the movement smoothness and connection stability of the conversion member 4 and the locking member 2.

[0055] In this embodiment, the locking slot 21 is provided on the locking member 2, and the locking connection structure is provided on the locking connection portion 41. Of course, in other embodiments, the locking slot 21 can also be provided on the locking connection portion 41, and the locking connection structure can be provided on the locking member 2.

[0056] Furthermore, the locking connection structure is a cylindrical structure, and the locking connection structure is fixed to the locking connection part 41. It is not only simple in structure and easy to produce, but also can improve the movement smoothness of the conversion member 4 and the locking member 2, and reduce the contact area between the locking connection structure and the inner wall of the locking groove 21, thereby reducing friction.

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

[0058] Optionally, the conversion member 4 further includes a frame connection portion 43 , and the frame connection portion 43 is slidably connected to the frame body 1 , thereby further supporting the conversion member 4 and improving the rotation stability of the conversion member 4 .

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

[0060] When the frame connection structure slides in the frame slide groove 11, it will abut against the inner wall of the frame slide groove 11, thereby supporting the conversion member 4, and will not interfere with the rotation of the conversion member 4. The structure is simple and easy to produce.

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

[0062] Furthermore, the frame connection structure is a cylindrical structure, and the frame connection structure is fixed to the frame connection part 43. It is not only simple in structure and easy to produce, but also can improve the movement smoothness of the conversion member 4, and reduce the contact area between the frame connection structure and the inner wall of the frame slide groove 11, thereby reducing friction.

[0063] In other embodiments, the frame connection structure may be configured in other shapes, and the frame connection structure may be rotatably disposed on the frame connection portion 43, which is not limited here.

[0064] Specifically, the conversion slot 42 is a first arc slot; the rack slot 11 is a second arc slot; and the locking slot 21 is a rectangular slot. Further, the center of the first arc slot and the conversion mounting portion 44 are both located on the same side of the first arc slot; the center of the second arc slot and the conversion mounting portion 44 are both located on the same side of the second arc slot. The above arrangement is conducive to improving the smoothness of the movement of the shifting member 6, the conversion member 4 and the locking member 2, and is convenient for processing and manufacturing.

[0065] Of course, in other embodiments, the conversion slot 42, the rack slot 11 and the locking slot 21 may also be configured as other shapes, which are not limited here.

[0066] Optionally, the conversion member 4 also includes a conversion mounting portion 44, which is rotatably connected to the frame body 1, and the locking connection portion 41, the frame connection portion 43 and the conversion mounting portion 44 are arranged in a triangle, which is beneficial to improve the movement smoothness and stability of the conversion member 4 and the shifting member 6.

[0067] Exemplarily, the conversion mounting portion 44 is rotatably connected to the frame body 1 via a rotation support such as a bearing, thereby improving the smoothness of the rotation of the conversion member 4 .

[0068] Optionally, one of the trigger member 5 and the shifting member 6 is provided with a hinge shaft 51, and the other of the trigger member 5 and the shifting member 6 is provided with a hinge hole 62, and the hinge shaft 51 is rotatably disposed in the hinge hole 62, which has a simple structure and is convenient for hinge connection between the trigger member 5 and the shifting member 6.

[0069] In this embodiment, the hinge shaft 51 is provided on the trigger member 5, and the hinge hole 62 is provided on the stop member 6. Of course, in other embodiments, the hinge shaft 51 can also be provided on the stop member 6, and the hinge hole 62 can be provided on the trigger member 5.

[0070] Optionally, the frame 1 is provided with a trigger slot 12, and the hinge shaft 51 is slidably arranged in the trigger slot 12 along the first direction, thereby supporting the trigger member 5 and limiting the extreme position of the trigger member 5 sliding along the first direction, which is beneficial to improving the movement smoothness and stability of the trigger member 5.

[0071] In other embodiments, the frame 1 may be provided with a triggering slot 12, the trigger member 5 may be provided with a triggering connection portion, and the triggering connection portion may be slidably disposed in the triggering slot 12. Of course, the trigger member 5 may be provided with a triggering slot 12, the frame 1 may be provided with a triggering connection portion, and the triggering connection portion may be slidably disposed in the triggering slot 12.

[0072] Optionally, one of the hinge shaft 51 and the hinge hole 62 is provided with a limit block 511, and the other of the hinge shaft 51 and the hinge hole 62 is provided with a limit groove, and the limit block 511 is arranged in the limit groove to prevent the blocking member 6 and the trigger member 5 from relative movement along the axial direction of the hinge shaft 51.

[0073] In this embodiment, the limit block 511 is provided on the hinge shaft 51, such as the outer circumference of the hinge shaft 51 or the end of the hinge shaft 51, and the limit groove is provided on the inner circumference of the hinge hole 62. In other embodiments, the limit block 511 can also be provided on the inner circumference of the hinge hole 62, and the limit groove can be provided on the outer circumference of the hinge shaft 51.

[0074] Optionally, the locking device further includes a driving mechanism, which includes a rotation driving unit, and the output shaft of the rotation driving unit is provided with a pushing portion, which is connected to the trigger member 5 to drive the trigger member 5 to slide along the first direction toward the direction close to the shifting member 6.

[0075] When the output shaft of the rotary drive unit rotates, the pusher can push the trigger member 5 to slide along the first direction toward the direction close to the stopper 6. In other words, the rotary drive unit only needs to provide a torque in a single direction to drive the trigger member 5 to slide along the first direction toward the direction close to the stopper 6, and the stopper 6 in the locking position can drive the conversion member 4 to rotate along the first circumferential direction, thereby causing the locking member 2 to slide and extend along the first direction for locking, or the stopper 6 in the unlocking position can drive the conversion member 4 to rotate along the second circumferential direction opposite to the first circumferential direction, thereby causing the locking member 2 to slide and retract along the first direction for unlocking. At the same time, using the rotary drive unit to provide torque to drive the trigger member 5 to slide is conducive to improving control accuracy.

[0076] Optionally, the rotary drive unit includes a rotary drive member and a worm gear assembly, the worm gear assembly includes a worm wheel and a worm that mesh with each other, the rotary shaft of the rotary drive member is fixedly connected to the worm, and the pushing portion is arranged on the worm wheel. Exemplarily, the rotary drive member is a motor. The pushing portion that rotates with the worm wheel pushes the trigger member 5 to slide along the first direction toward the direction close to the shift member 6. At the same time, the worm gear assembly can also play a role of deceleration 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 gear assembly, which is not limited here.

[0077] Exemplarily, the working principle of the locking device of this embodiment is:

[0078] It should be noted that if Figures 3 to 5 As shown, for the convenience of description, one end of the conversion slot 42 close to the locking member is recorded as a first end 421 , and the other end of the conversion slot 42 is recorded as a second end 422 .

[0079] like 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 at this time, 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, 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 along 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 in the conversion slot toward the second end 422, so that the stop member 6 switches to the unlocking position. At the same time, the driving mechanism is reset to prepare 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, such as Figure 5 As shown, the driving mechanism operates again and drives the trigger member 5 to slide again along the first direction toward the direction close to the shift member 6, and then squeezes the reset elastic member 7 again, so that the reset elastic member 7 produces elastic deformation again; at the same time, the trigger member 5 drives the shift member 6 in the unlocking 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 unlocking state. At this time, under the action of the locking elastic member 3, the locking member 2 remains in the unlocking 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 along 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 in the conversion slot toward the first end 421, so that the stop member 6 switches to the locking position. At the same time, the driving mechanism is reset again to prepare for the next locking of the locking member 2.
