Technical Field

Cabinets such as a safe cabinet, an ATM and the like have higher requirements on safety, and the door is locked by adopting a mode of locking a door bolt mechanism by an electronic lock. When the door is locked, the bolt mechanism extends out, the electronic lockset props against the bolt through the lock tongue, and the bolt cannot return. When the door is opened, the electronic lock retracts the lock tongue, and the door can be opened. The locking control of the electronic lock is an important part of the electronic lock. Generally, how long a user closes a door after opening the door is uncertain, and at present, there are three main methods in the lock closing control aspect: firstly, a sensor is arranged on a box door, and after the door is detected to be closed, a controller controls a driving motor to start, so that the locking is closed. This method relies on sensors, control circuitry is complex, and reliability is relatively low. And secondly, a lock closing button or a lock closing knob which is manually controlled is arranged, and after the door is closed, the lock is closed by manually pressing the lock closing button or manually rotating the lock closing knob through a circuit control or mechanism transmission mechanism. This method has the disadvantage that once the user forgets to turn the lock off, the money in the tank is put at risk.

Aiming at the problems of low reliability of a sensor, complete dependence of manual control on user operation and the like, a novel lock closing control method is provided in the industry. After the user unlocks the lock, the controller controls the motor to start in a delayed mode. The motor outputs energy to the energy storage mechanism, when the box door is closed, the energy storage mechanism releases energy, the bolt is pushed out through the lock tongue, and locking is completed.

Detailed Description

The energy storing mechanism of the lock of the present invention is further explained by taking a specific lock structure as an example and combining the drawings.

Referring to fig. 1, the lock shown in the figure is in a locked state, in this example, the lock body of the lock is a square lock body 1 with four smooth corners and round corners, and the bolt 2 and the movable plate 3 are slidably disposed along the center line of the lock body and are in a vertical parallel relationship with each other. The rear part of the lock body is close to the right side and is provided with a motor 6 and a worm gear reduction box 5 connected with the motor. Wherein, the worm is coaxially connected with the output shaft of the motor, the worm wheel is assembled with the screw rod 4, the screw rod 4 is positioned above the movable plate 3, and the screw rod 4 is also arranged along the central line of the lock body. The screw rod is sleeved with a thread bush 7. The movable plate is provided with an assembly square hole 302, the bottom of the threaded sleeve is provided with a bulge, and the bulge at the bottom of the threaded sleeve is embedded in the assembly square hole 302 on the movable plate.
