A door lock capable of emergency power generation

Abstract

This application provides a door lock capable of generating electricity in an emergency. The door lock includes a lock cylinder, a mounting bracket, a lock cylinder shaft, a power generation module, a power storage module, a lock cylinder cover, and a connecting assembly. The lock cylinder shaft is rotatably mounted on the mounting bracket and has a lock cylinder hole for accommodating the lock cylinder. The power generation module is mounted on the mounting bracket and is drive-connected to the lock cylinder shaft. The power storage module is mounted on the mounting bracket and stores the electrical energy generated by the power generation module. The lock cylinder cover is drive-connected to the lock cylinder shaft via the connecting assembly. When the lock cylinder cover is in the closed state, it is connected to the mounting bracket and covers the lock cylinder; when the lock cylinder cover is in the open state, it separates from the mounting bracket, exposing the lock cylinder; when the lock cylinder cover is in the rotation power generation state, it rotates, thereby driving the lock cylinder shaft to rotate, which in turn drives the power generation module to generate electricity. This solution improves the convenience of emergency unlocking and reduces the space occupied by the door lock.
