Door lock mechanism with redundant design

Abstract

The invention discloses a door lock mechanism with redundant design. The door lock mechanism comprises a lock core body, and a shifting fork is arranged in the middle of the lock core body; an outer unlocking mechanism is connected to the outer side of the lock core body; an inner unlocking mechanism is connected to the inner side of the lock core body; an unlocking device is arranged on the outerunlocking mechanism; an antenna and a sliding block are arranged in the inner unlocking mechanism; the antenna can receive a signal sent by a controller; the antenna is in drive connection with the sliding block; and when the antenna receives an unlocking instruction sent by the controller, the antenna drives the sliding block to rotate. Through adoption of the structure, when the outer unlockingmechanism breaks down, a user can open the door lock through the inner unlocking mechanism, reliability is high, power consumption is low, and the user can enter a room at any time through the double-insurance mechanism.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to a door lock mechanism with redundant design. Background technique [0002] The common mechanical door lock mechanism basically controls the opening and closing of the lock on one side of the door directly through the key. Once the key is lost or there is a mechanical failure inside the lock cylinder, you can only seek a professional lock company to unlock or tamper with it, which is extremely inconvenient to use and may even bring safety hazards. [0003] At present, the unlocking mechanism of most electronic door locks is through an external verification mechanism, such as fingerprint, swipe card or portrait recognition technology, to drive the motor, and through the transmission mechanism such as gears, to realize the unlocking action, or if the external verification mechanism fails, then through random matching A special mechanical key is inserted into the lock hole to unl...

[0003] At present, the unlocking mechanism of most electronic door locks is through an external verification mechanism, such as fingerprint, swipe card or portrait recognition technology, to drive the motor, and through the transmission mechanism such as gears, to realize the unlocking action, or if the external verification mechanism fails, then through random matching The mechanical key is inserted into the lock hole to unlock the lock. This mechanism also cannot solve the problems of mechanical door locks, such as the inconvenience caused by key loss and mechanical failure.
