[0015] The technical solution of the present utility model has the following advantages compared with the prior art:

[0016] 1. In the electric lock plate provided by the present utility model, the return mechanism is composed of a return protrusion, a guide groove and a spring structure, and the spring structure is arranged on the movement path of the return protrusion. With this structural arrangement, when the driving wheel drives the lock hook to complete unlocking, since the motor is still running, the driving wheel will drive the return protrusion to squeeze the spring structure, and at the same time, the driving gear and the transmission gear are disengaged from meshing. At this time, the spring structure is squeezed and in an energy storage state. Therefore, as long as the motor stops running, the spring structure uses its elastic force to drive the driving wheel and the driving gear to rotate back a certain stroke, so that the driving gear coincides and meshes with the transmission gear after a short period of tooth disengagement. The gear biting force is released during the tooth disengagement period to prevent tooth jamming, effectively protecting the motor.

When the locking hook needs to be unlocked, the driving wheel rotates forward under the drive of the motor, and the locking hook is pushed by the driving block to separate from the lock catch to complete the unlocking operation. At the same time, the convex rod structure is driven into the guiding groove to squeeze one end of the arc-shaped spring. After the motor stops, the driving wheel will drive the driving gear to rotate back under the action of the arc-shaped spring, so that the disengaged driving gear and the transmission gear are re-engaged. Such a design enables the driving gear and the transmission gear to both experience the process of first disengaging and then re-engaging during the locking and unlocking of the product. This not only solves the problem that the gear cannot return to its position when disengaged, protects the motor well, but also avoids the situation of gear meshing transmission failure, making it safe and reliable to use, thereby improving the service life and performance of the product.

[0030] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Embodiment

[0032] The following is a specific description of this embodiment in conjunction with the accompanying drawings:

[0033] The present utility model provides as Figures 1-7The electric lock plate 1 shown in the figure comprises a lock plate 1, an electric control assembly, and a lock catch 11 and a lock hook 12 which are respectively rotatably arranged on the lock plate 1, wherein the lock hook 12 has a locking position which is rotatably engaged with the lock catch 11, and an unlocking position which is rotatably separated from the lock catch 11; the electric control assembly comprises an electric control box 2 and a motor 3 which is connected to the electric control box 2, a gear assembly and a driving wheel 6, wherein the gear assembly comprises a meshing transmission gear 4 and a driving gear 5, wherein the driving gear 5 is a semi-tooth structure and is coaxially arranged with the driving wheel 6 , the pushing wheel 6 pushes the lock hook 12 to unlock under the drive of the driving gear 5, a push-back protrusion 7 deviating from its axis is provided at the bottom of the pushing wheel 6, and a guide groove extending along the movement trajectory of the push-back protrusion 7 is provided on the electric control box 2, and a spring structure 8 is provided in the guide groove; when the pushing wheel 6 drives the lock hook 12 to unlock, the push-back protrusion 7 squeezes the spring structure 8, and the spring structure 8 applies an elastic force to the pushing wheel 6 to drive the driving gear 5 to rotate a certain stroke.

[0034] The above implementation is the core technical solution of this embodiment. A push-back mechanism is formed by the push-back protrusion 7, the guide groove and the spring structure 8. The spring structure 8 is arranged on the movement path of the push-back protrusion 7. With this structural arrangement, when the driving wheel 6 drives the lock hook 12 to complete the unlocking, since the motor 3 is still running, the driving wheel 6 will drive the push-back protrusion 7 to squeeze the spring structure 8, and at the same time, the driving gear 5 and the transmission gear 4 will be disengaged. At this time, the spring structure 8 is squeezed and is in an energy storage state. Therefore, as long as the motor stops running, the spring structure 8 uses its elastic force to drive the driving wheel 6 and the driving gear 5 to rotate a certain stroke, so that the driving gear 5 overlaps and meshes with the transmission gear 4 after a short tooth disengagement, and the gear bite force is released during the tooth disengagement to prevent the gear from getting stuck, which effectively protects the motor 3. The push-back mechanism of this technical solution solves the problem of the difficulty of returning the gear after tooth disengagement, ensures the stability and reliability of the transmission between the motor, the gear assembly and the driving wheel, and avoids the situation where the gear meshing transmission fails when the motor is started next time. It has a simple structure, good safety in use, and a wide range of applications.

[0035] Combine the following Figures 2-6 The specific setting method of the push-back mechanism is described in detail:

[0036] The backward pushing protrusion 7 moves along an arc trajectory driven by the driving wheel 6. The guiding groove is an arc groove provided in the electric control box body 2. The spring structure 8 is an arc-shaped spring fitted in the arc groove. During the rotation of the driving wheel 6, the backward pushing protrusion 7 squeezes the two ends of the arc-shaped spring respectively. Specifically, the backward pushing protrusion 7 is a convex rod structure offset from the center axis and arranged at the bottom of the driving wheel 6. The convex rod structure is arc-shaped. The driving wheel 6 includes a driving protrusion offset from the center axis and arranged at its top. The locking hook 12 is located on the movement path of the driving protrusion. The driving protrusion drives the locking hook 12 to complete the unlocking movement under the drive of the driving wheel 6. With this structural arrangement, during the unlocking operation of the electric lock plate 1, the motor 3 drives the driving wheel 6 to rotate forward, so that the driving wheel 6 drives the locking hook 12 to rotate to the unlocking position. When the driving wheel 6 rotates forward, it drives the convex rod structure to enter one end of the guiding groove and squeeze one end of the arc-shaped spring. At this time, the arc-shaped spring will exert a reverse pushing force on the driving wheel 6 and the driving gear 5. Correspondingly, during the locking operation of the electric lock plate 1, the motor 3 drives the driving wheel 6 to rotate backward, so that the driving wheel 6 rotates away from the locking hook 12 to make way for the locking movement of the locking hook 12. When the driving wheel 6 rotates backward, it drives the convex rod structure to enter the other end of the guiding groove and squeeze the other end of the arc-shaped spring. At this time, the arc-shaped spring also exerts a reverse pushing force on the driving wheel 6 and the driving gear 5. It can be seen that the motor 3 can rotate forward and backward. The driving wheel 6 can drive the backward pushing protrusion 7 to squeeze the spring structure 8 whether it rotates forward or backward under the drive of the motor 3, so as to use the acting force of the spring structure 8 to realize the re-engagement of the driving gear 5 and the transmission gear 4 after tooth disengagement. The forward and backward rotations mentioned in this article refer to the two rotation directions of a certain part being opposite to each other.

[0037] An installation groove 21 suitable for installing the driving wheel is provided on the electric control box body 2. The guiding groove is arranged in the installation groove 21. The driving wheel 6 covers the upper side of the guiding groove and the spring structure 8. Two groups of limiting convex platforms that cooperate with and abut against the two ends of the arc-shaped spring are provided at the two ends of the guiding groove. With this structural arrangement, the top-side opening of the guiding groove is covered by the driving wheel 6, which restricts the arc-shaped spring from detaching from the top-side opening position of the guiding groove. And the two groups of limiting convex platforms are used to limit the two ends of the arc-shaped spring from extending out of the guiding groove, which plays a role in limiting the installation of the arc-shaped spring in the guiding groove and also prevents the arc-shaped spring from being exposed. The installation is stable and reliable. At the same time, according to the convex rod structure, it is installed in the installation groove 21 together with the driving wheel 6, and the backward pushing mechanism is composed of the convex rod structure, the arc-shaped spring and the guiding groove. This backward pushing mechanism has a simple structure, occupies a small installation space, is convenient to install, has reliable cooperation and low cost, and uses the elastic force of the arc-shaped spring under compression deformation to push the driving wheel 6 and the driving gear 5 to achieve the purpose of rotation.

[0038] To prevent the driving wheel 6 from disengaging and falling out of the installation groove 21, as shown in combination with Figures 3-5 、 Figure 7 An arc-shaped limiting chute 22 is provided on the groove wall of the installation groove 21. The limiting chute 22 is arranged higher than the guiding chute. A circular ring convex edge 62 rotatably connected to the limiting chute 22 is provided on the outer periphery of the driving wheel. Further, a slot opening 23 communicating with the limiting chute 22 is formed on the side of the installation groove 21 away from the arc-shaped spring. The driving wheel 6 is inserted into the installation groove 21 from the slot opening 23. A blocking portion 13 inserted into the slot opening 23 is provided on the lock plate 1. The blocking portion 13 has an arc edge arranged around the outer periphery of the driving wheel 6. With this structural arrangement, the limiting cooperation formed by the circular ring convex edge 62 and the limiting chute 22 can prevent the driving wheel 6 from disengaging from the top opening of the installation groove 21, and the blocking portion can limit the driving wheel 6 from disengaging from the position of the slot opening 23, thereby limiting and installing the driving wheel 6 in the installation groove 21. Among them, the motor 3 and the gear assembly are installed in the electric control box body 2. A through hole communicating with the inner cavity of the electric control box body 2 is provided at the bottom of the installation groove 21. An arc-shaped wall is formed between the guiding chute and the through hole. A keyway structure 63 is provided at the center of the bottom of the driving wheel 6. A key block structure 51 coaxially provided on the driving gear 5 and passing through the through hole and connected to the keyway structure 63 to form a linkage fit is provided. The key block structure 51 is a spline block, and the keyway structure 63 is correspondingly designed as a spline groove. According to the installation groove 21 being arranged on the outer side surface of the electric control box body 2, the key block structure 51 passes through the through hole and is matched and connected with the keyway structure 63, so as to realize the transmission of torque between the driving gear 5 and the driving wheel 6.

[0039] A plurality of positioning grooves 24 are provided on the same side of the electric control box body 2. A plurality of positioning blocks inserted into the plurality of positioning grooves 24 are correspondingly provided on one side edge of the lock plate 1. The opening direction of the slot opening 23 is the same as the opening direction of the positioning grooves 24. The blocking portion is one of the positioning blocks. With this structural arrangement, the relative position between the lock plate 1 and the electric control box body 2 is positioned through the cooperation of the positioning grooves 24 and the positioning blocks, and then the two are fixedly connected through a fastening structure. The fastening structure is preferably a screw structure. With such an installation design, the lock plate 1 does not need to limit and block the position of the rotating wheel, that is, the lock plate does not need to cover the entire surface of the electric control box body where the driving wheel is provided. Therefore, the installation contact area between the lock plate 1 and the electric control box body 2 can be reduced, and thus the area of the lock plate can be made smaller, which is beneficial to cost reduction.

[0040] A tension spring structure is connected between the locking hook 12 and the locking latch 11. That is, when unlocking, the locking latch 11 and the locking hook 12 can be quickly rotated and separated through the tension spring structure. A detection switch 10 for detecting whether the locking hook 12 and the locking latch 11 are in the unlocked state or the locked state is provided on the locking plate 1 or the electric control box 2. As Figure 1 shown, the detection switch 10 has a trigger piece that extends obliquely on the movement path of the locking latch 11. The trigger piece is an elastic structure. The detection switch is preferably a micro switch. The bottom end of the locking latch 11 presses against the trigger piece during rotation. The detection switch 10 sends an indication signal for indicating the unlocking or locking of the electric locking plate when the trigger piece is pressed.

[0041] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
