Abstract
Description
[Technical field]
[0001] The utility model relates to an electronic door lock. [Background technology]
[0002] Electronic locks, especially electronic door locks, usually control the circuit or chip operation through password input, thereby controlling the mechanical unlocking and locking tasks. The password input operation can be performed through traditional mechanical input methods such as key-type and dial-type, or through more advanced electronic keys (which transmit electronic signals to the control circuit inside the electronic door lock through sound, light, electromagnetic waves, etc.) and biometrics (human biological characteristics, such as sound, iris, fingerprints, etc., are input through specific input devices).
[0003] Existing electronic door locks have the following defects: 1. The handle assembly inside the door does not have a privacy anti-lock function, which is inconvenient to use; 2. The clutch pin seat in the handle assembly outside the door and the square rod that cooperates with it rely on the lock body for reset. During installation, the user needs to manually adjust the direction of the square rod before inserting it into the lock body, which is prone to errors; and due to the clearance fit problem, the reset relying on the lock body may sometimes fail to reset correctly, causing the clutch to fail to work properly.
