[0058] In a preferred embodiment, as shown in Figures 1 to 5 , Figure 9 The driving assembly includes a motor 410 fixedly arranged on the mounting frame 100, and a worm member 420 fixedly arranged on a power output end of the motor 410.

[0059] The driving assembly further includes a linkage gear 430 and a linkage worm 450 rotatably arranged on the mounting frame 100, the linkage gear 430 is engaged with the worm member 420, and the linkage worm 450 includes a worm transmission section 452 rotatably connected with the mounting frame 100 and a linkage straight tooth portion 451 fixedly arranged on the worm transmission section 452 and coaxial with the worm transmission section 452.

[0061] It can be understood that when the motor 410 drives the worm member 420 to rotate, the linkage gear 430 and the linkage worm 450 can be synchronously driven to rotate, thereby driving the lifting plate 220 to move along the axial direction on the worm transmission section 452, and further driving the locking rod 210 to synchronously move to realize the locking or unlocking action.

[0062] In the embodiment of the present application, the above-mentioned automobile charging gun locking device is adopted, the transmission between the worm member 420 and the locking member 200 is realized through the linkage worm 450, thereby realizing the one-way transmission from the motor 410 to the locking member 200 and the reverse self-locking, and ensuring the locking stability and reliability of the locking member 200 after the locking action is performed.

[0063] It can be understood that in order to prevent the locking lifting plate 220 from following the linkage worm 450 to rotate when the linkage worm 450 is driven to rotate to drive the locking member 200 to move, the rotating limiting structure of the locking member 200 is arranged on the mounting frame 100, which can be specifically arranged as the slide rail structure of the locking member 200 on the mounting frame 100, or the limiting stopper is arranged in the rotating direction of the locking member 200, as long as the moving stability of the locking member 200 can be ensured, and details are not described herein.

When the locking member 200 linearly moves to perform the locking or unlocking action, the relative position between the sensing contact 620 and the control plate 610 changes, and when the relative position between the sensing contact 620 and the control plate 610 reaches the predetermined locking or unlocking position, the control plate 610 can control the motor 410 to stop driving, thereby realizing the accurate positioning of the working position of the locking member 200.

[0068] The support spring 520 is arranged between the sensing contact 620 and the inner wall of the embedding groove of the lifting plate 220.

[0069] It can be understood that the elastic sliding of the inductive contact 620 relative to the locking member 200 can be realized by the supporting spring 520, so that the contact stability of the inductive contact 620 relative to the control plate 610 can be ensured when the locking member 200 moves relative to the control plate 610.

[0073] It can be understood that the transmission gear 440 can drive the toothed plate member 460 to linearly move relative to the mounting frame 100 when the transmission gear 440 rotates, and the toothed plate member 460 can drive the unlocking member 300 to rotate relative to the mounting frame 100 when the toothed plate member 460 linearly moves through the cooperation of the first tooth portion 461 and the driven gear 470; conversely, the toothed plate member 460 can linearly move relative to the mounting frame 100 when the unlocking member 300 is rotated relative to the mounting frame 100 by the operation of an operator, and the transmission gear 440 and the linkage gear 430 can be driven to rotate through the cooperation of the driven gear 470, the first tooth portion 461, the second tooth portion 462, the second transmission gear segment 442 and the linkage gear 430, so that the linear movement of the locking member 200 can be reset and unlocked.

[0076] It can be understood that, by setting the diameters of the first transmission gear segment 441 and the second transmission gear segment 442, the driving torque of the transmission gear 440 on the toothed plate 460 is increased, and at the same time, the driving process of the locking member 200 is decelerated when the manual unlocking is performed by the unlocking member 300, so as to ensure the reliability of the unlocking action and the overall stability of the electronic lock device.

[0077] In a preferred embodiment, as shown in Figures 2 to 5 , Figure 8 The linkage gear 430 includes coaxial and sequentially fixed first linkage gear segment 431, second linkage gear segment 432, and third linkage gear segment 433.

[0082] When the toothed plate 460 moves linearly relative to the mounting frame 100, the reset spring 510 can accumulate the elastic potential energy for resetting the toothed plate 460.

[0083] It can be understood that when the driving assembly drives the locking member 200 to perform the locking action, the unlocking member 300 rotates synchronously, and the toothed plate 460 accumulates the elastic potential energy; when the operator manually unlocks through the unlocking member 300, the toothed plate 460 can drive the unlocking member 300 to reset through the elastic potential energy accumulated by itself, so as to reduce the force required by the operator to operate the unlocking member 300 and reduce the difficulty of manual unlocking of the operator.
