Kind Code:
A1
Abstract:
A device and method for preventing a door lock from being unlocked by an abnormal method and a door. The device comprises a sensor configured to sense a human body signal, a controller connected to the sensor, and a driving assembly configured to control whether a door handle (1) is in linkage with a lock body (14) or not; when the sensor detects the human body signal, the controller controls the driving assembly to enable the lock body (14) to be in linkage with the door handle (1), and the door lock can be unlocked by rotating the door handle (1); when the sensor does not detect the human body signal, the controller controls the driving assembly to enable the lock body (14) not to be in linkage with the door handle (1), and the door lock cannot be unlocked by rotating the door handle (1). Only when a human body is close to the sensor, the lock body (14) and the door handle (1) can be connected to unlock the door lock, and in a normal state, the lock body (14) and the door handle (1) are in a disconnected state, and the door lock cannot be unlocked under the condition that the door handle (1) is rotated by other tools. The step of pressing a cat eye prevention button switch during door opening is omitted, user experience is improved, and door opening is more convenient and faster.
