Description

Technical Field

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

[0002] In the field of door locks, with the development of intelligent technology, electric unlocking has gradually become the mainstream unlocking method due to its advantages such as ease of operation. Currently, most mainstream electric door locks rely on battery power or an external power source to drive the motor, which in turn drives the lock cylinder to retract or extend through a transmission mechanism to achieve the unlocking or locking function. However, in practical applications, these door locks that rely solely on electric unlocking will fail in situations such as battery depletion without backup power, sudden malfunctions in the electronic control system, forgotten passwords, or biometric authentication failures. Users will often find themselves unable to open the door. To avoid this problem, existing electric door locks typically integrate a mechanical emergency unlocking function. However, in the current design of door locks integrating both electric and mechanical unlocking functions, the integration of mechanical and electric unlocking is relatively low, with both modules containing numerous transmission components, resulting in a complex internal structure.

[0003] Therefore, it is necessary to propose an emergency unlocking structure for the lock body to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved The purpose of this utility model is to provide an emergency unlocking structure for lock bodies, so as to solve the problems of low integration and complex structure of existing mechanical and electric unlocking methods mentioned in the background art.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-4 As shown, an emergency unlocking structure for a lock body includes a base plate 4, a transmission plate 13 slidably connected to the base plate 4, a lock head 5 connected to one end of the transmission plate 13, and a protrusion 6 provided at the other end of the transmission plate 13. A mechanical lock 12 is fixedly connected to the base plate 4 at a position corresponding to the protrusion 6. A paddle 2 is fixedly connected to the rotating bolt of the mechanical lock 12. The paddle 2 cooperates with the protrusion 6 to drive the transmission plate 13 to slide. A limiting groove 10 is provided on the transmission plate 13. A traction block 9 slides in the limiting groove 10 along the sliding direction of the transmission plate 13. A spring 11 is provided on the side of the traction block 9 near the lock head 5. A connecting plate 15 is fixedly connected to the other side of the traction block 9. The connecting plate 15 is driven by a motor 3 to move back and forth.

[0017] During electric unlocking, the motor 3 drives the connecting plate 15 to slide, and the connecting plate 15, through the traction block 9, pulls the transmission plate 13 to slide synchronously, thereby moving the lock head 5 to perform the unlocking action. In case of an unexpected situation where the motor 3 cannot drive the lock head 5 to perform the unlocking action, the mechanical lock 12 drives the lever 2 to rotate. The lever 2 acts on the protrusion 6 to drive the transmission plate 13 to slide, and the transmission plate 13 moves the lock head 5 to perform emergency unlocking. During emergency unlocking, the spring 11 is compressed. When the lever 2 returns to its original position, the lock head 5 automatically returns to its original position under the action of the spring 11, without affecting its normal locking function.

[0018] Specifically, a strip-shaped slot 8 is provided on the connecting plate 15 perpendicular to the sliding direction of the transmission plate 13. A push-button 7 is inserted into the strip-shaped slot 8, and the push-button 7 is driven to rotate by the motor 3. In use, the motor 3 drives the push-button 7 to rotate, and with the cooperation of the push-button 7 and the strip-shaped slot 8, the motor 3 drives the connecting plate 15 to move back and forth. When locked, the position of the push-button 7 is as follows: Figure 2 As shown, under the action of spring 11, the lock head 5 extends as follows. Figure 1 The state shown.

[0019] To provide feedback on the position of the connecting plate 15, a toggle block 18 is fixedly connected to one side of the connecting plate 15, and a limit switch 14 is fixedly connected to the base plate 4 at a position corresponding to the toggle block 18. Both the motor 3 and the limit switch 14 are connected to the controller 1. The limit switch 14 is positioned to limit the position of the insert plate 16 when the protrusion 6 extends, thus triggering the limit switch 14. After the limit switch 14 is triggered, it sends a signal to the controller 1 for status feedback and ensures that the motor 3 stops promptly after reaching the target position to avoid over-rotation.

[0020] To limit the movement of spring 11, spring 11 is positioned within limiting groove 10. A cavity is provided within traction block 9 to accommodate spring 11. Limiting insert plate 16 is fixedly connected to the limiting groove 10 at a position corresponding to spring 11. With the cooperation of the cavity and limiting insert plate 16, both ends of spring 11 are limited to prevent positional deviation.

[0021] Specifically, one end of the mechanical lock 12 with a lock hole extends to the other side of the base plate 4, and a baffle 20 is fixedly connected to the base plate 4 at the position corresponding to the lock hole of the mechanical lock 12. By setting the baffle 20, the mechanical lock 12 is protected, which can prevent dust and other impurities from entering the lock hole of the mechanical lock 12, so as to avoid affecting its normal use and extend its service life.

[0022] To facilitate opening the baffle 20, rotating shafts 21 are fixedly connected to both sides of the baffle 20. The baffle 20 is rotatably connected to the base plate 4 via the rotating shafts 21. A plug 19 is fixedly connected to one end of the baffle 20. A limiting slot 17 is provided on the base plate 4 at the position corresponding to the plug 19. When opening the baffle 20, pressing the end of the baffle 20 without the plug 19 causes the baffle 20 to rotate around the rotating shaft 21, generating elastic deformation that disengages the plug 19 from the limiting slot 17. Then, rotating the baffle 20 exposes the lock hole. Specifically, the outer side of the pressing end of the baffle 20 is provided with anti-slip stripes, and the baffle 20 is made of elastic sheet.

[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.
