Description

An electronic lock body and its switch lock structure

technical field

The invention relates to the field of locks, in particular to an electronic lock body and a switch lock structure thereof.

Background technique

At present, door locks sold on the market can be roughly divided into two types, namely mechanical door locks and electronic door locks.

The so-called mechanical door lock refers to the mechanical connection between the various parts of the entire lock body. This type of door lock is widely used in life. The usual structure of the unlocking device of the mechanical lock is through the lock cylinder dial on the lock cylinder and the door handle to actuate the main tongue assembly and latch bolt assembly for unlocking and closing.

The electronic door lock is based on the mechanical door lock, adding an electronic unlocking mechanism. The general structure of the electronic lock unlocking device is: the motor drives the main tongue assembly and the oblique tongue assembly through the gear transmission mechanism to unlock. However, many gear transmission mechanisms of existing electronic door locks do not have a clutch function, so that when the emergency key is used to drive the lock cylinder to rotate to manually unlock the key, it is necessary to overcome the self-locking force of the motor and the gear transmission mechanism itself to unlock the lock. When the key is manually unlocked, the resistance is large, and the user experience of unlocking is poor. At the same time, if the motor burns out or is stuck, there may be situations where the key cannot be manually unlocked, and there are certain security risks.

In view of the above problems, it is necessary to study an electronic lock body and its switch lock structure to overcome the shortcomings of the existing electronic door locks.
