Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a lock body transmission structure. Background Technology

[0002] Current automatic unlocking mechanisms mostly rely on complex gear transmissions or multi-link combinations. A motor drives multiple transmission components to move sequentially, ultimately causing the lock head to retract and complete the unlocking process.

[0003] Because multi-stage transmission structures involve a large number of parts, they not only result in a large overall size, making it difficult to adapt to the design requirements of miniaturized and lightweight locks, but also increase the precision requirements for parts processing and the complexity of assembly processes.

[0004] Therefore, it is necessary to propose a lock body transmission structure to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figure 1-3As shown, a lock body transmission structure includes a base plate 5, a transmission plate 3 slidably connected to the base plate 5, a lock head 6 connected to one end of the transmission plate 3, a limiting groove 11 on the transmission plate 3, a traction block 10 sliding within the limiting groove 11 along the sliding direction of the transmission plate 3, a return spring 12 on the side of the traction block 10 near the base plate 5, and a connecting plate 4 fixedly connected to the other side of the traction block 10. A strip-shaped slot 9 is formed on the connecting plate 4 perpendicular to the sliding direction of the transmission plate 3, and a push-button 8 driven by a motor 2 is inserted into the strip-shaped slot 9. The push-button 8 cooperates with the strip-shaped slot 9 to drive the connecting plate 4 to reciprocate. Specifically, the motor 2 is fixedly connected to the base plate 5, and the push-button 8 is fixedly connected to the output shaft of the motor 2.

[0019] When the lock head 6 needs to retract, motor 2 drives the latch 8 to rotate clockwise. The latch 8 acts on the strip slot 9, driving the connecting plate 4 to move. The connecting plate 4, through the traction block 10, pulls the transmission plate 3 to move synchronously, thereby causing the lock head 6 to retract and reach the unlocked state. When the lock head 6 needs to extend, motor 2 drives the latch 8 to rotate counterclockwise. The latch 8 acts on the strip slot 9, driving the connecting plate 4 to move. Under the action of the return spring 12, the lock head 6 is pushed out. By setting the return spring 12, the lock head 6 can automatically extend after being retracted by external force, so as to lock. Preferably, motor 2 is a servo motor to achieve precise angle control and locking.

[0020] To provide feedback on the status of the connecting plate 4, a toggle block 14 is fixedly connected to one side of the connecting plate 4. A limit switch 7 is fixedly connected to the base plate 5 at a position corresponding to the toggle block 14. A controller 1 is fixedly connected to the base plate 5, and both the motor 2 and the limit switch 7 are connected to the controller 1. Specifically, the limit switch 7 is positioned at the location of the toggle block 14 when the lock head 6 is extended. When the limit switch 7 is triggered, it sends a signal to the controller 1 to complete the status feedback and ensure that the motor 2 stops in time after reaching the target position to avoid over-rotation.

[0021] To limit the position of the return spring 12, the return spring 12 is arranged in the limiting groove 11. The traction block 10 has a cavity for accommodating the return spring 12. A limiting plate 15 is fixedly connected to the limiting groove 11 at a position corresponding to the return spring 12. With the cooperation of the cavity inside the return spring 12 and the limiting plate 15, both ends of the spring are limited to prevent their position from shifting.

[0022] In some embodiments, a T-shaped block 16 is fixedly connected to one end of the transmission plate 3, and a T-shaped groove 13 adapted to the T-shaped block 16 is provided on one side of the lock head 6. By providing the T-shaped groove 13 and the T-shaped block 16, the assembly of the transmission plate 3 and the lock head 6 is made more convenient. In order to limit the lock head 6 and the traction block 10, a limiting cavity 17 is provided on one side of the base plate 5, and the lock head 6 and the traction block 10 are slidably arranged in the limiting cavity 17. Under the action of the limiting cavity 17, the lock head 6 is prevented from sliding along its length direction, and the traction block 10 is prevented from sliding out of the slot of the limiting slide groove 11. Specifically, a detachable cover plate is connected to the limiting cavity 17 by screws to facilitate the assembly of various structural components.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
