Description

Technical Field

[0001] The utility model relates to the technical field of lock bodies, in particular to an electric lock body. Background Art

[0002] The most traditional door locks generally use a mechanical opening method with a manual key. Although it is more reliable to use, it is more difficult to achieve automatic control, and it is not as easy as electric door locks to change the opening and locking conditions. Later, the industry began to adopt electrically controlled door locks, which can be identified by infrared, fingerprint, card swiping, password, etc., and the logic circuit controls the rotation of the motor to drive the lock tongue to open and lock. In order to avoid the situation where the door body cannot be opened or locked due to electric control failure, many electric door locks still retain the mechanism lock structure that is opened and locked by key.

[0003] In the related art, there are usually two types of electric door locks, one using a mechanical lock body with a rear panel motor drive structure, and the other using a built-in motor drive structure. However, the former has poor structural matching accuracy, serious efficiency loss, and unstable output torque; the latter has low power conversion efficiency or small output torque, and the application effect is also poor. Utility Model Content
