The unlocking controller can adopt the existing fingerprint unlocking controller, IC card unlocking controller, retina unlocking controller and the like. The door magnetic switch 9 is connected with the lock plunger driving mechanism and the lock plunger redundant driving mechanism, and triggers and controls the lock plunger driving mechanism and the lock plunger redundant driving mechanism to drive the linkage mechanism to drive the lock plunger mechanism to move forwards to lock the door after the door is closed. The door magnetic switch can be realized by adopting the existing door magnetic switch.
Of course, in order to realize that the door can be automatically sprung open when unlocking, a door spring can also be arranged on the door, so that the door is automatically opened when the lock is opened.
The working principle of the intelligent safety anti-theft door lock of the invention is as follows: when the lock is in a locked state, the lock plunger mechanism moves to a forward stroke position, the lock plunger is inserted into the lock hole, the lock plunger of the world lock is inserted into the lock hole of the world lock, after the unlocking controller receives an unlocking signal, the unlocking controller controls the lock plunger driving mechanism and the lock plunger redundant driving mechanism to drive the linkage mechanism to drive the lock plunger mechanism to move backwards, in the process of the backward movement of the lock plunger mechanism, a poking piece on the lock plunger connecting part contacts with a driving block of the lock plunger driving part to drive the driving block to move backwards, so that the lock plunger is driven to move backwards. Meanwhile, the lock plunger mechanism drives the world lock driving mechanism to move towards the inner side of the lock, and drives the world lock plunger to move towards the inner side of the lock. The driving block moves downward while the driving block moves backward. When the driving block and the toggle piece are about to be separated from contact, the lock bolt and the lock tongue are separated from the lock hole, the lock bolt of the world lock is also separated from the lock hole of the world lock, and the lock is opened, so that the door can be opened at the moment. When the door flickers are arranged, the door is automatically opened under the action of the door flickers. The unlocking controller controls the lock bolt driving mechanism and the lock bolt redundant driving mechanism to drive the linkage mechanism to drive the lock bolt mechanism to move backwards again, the driving block is separated from contact with the poking piece, and under the elastic force of the reset mechanism, the lock bolt driving part is driven to reset to drive the lock bolt to reset. When the lock bolt mechanism moves to the back stroke position, the stroke switch sends out an in-place signal to control the lock bolt driving mechanism and the lock bolt redundant driving mechanism to stop working, and the lock bolt mechanism stops moving.
When the door is locked, the lock tongue moves backwards firstly and then resets under the action of the elastic force of the reset mechanism to be inserted into the lock hole, when the door magnetic switch senses that the door is closed, the door magnetic switch is triggered to control the lock plunger driving mechanism and the lock plunger redundant driving mechanism to drive the linkage mechanism to drive the lock plunger mechanism to move forwards, meanwhile, the lock plunger mechanism drives the world lock driving mechanism to move towards the outer side of the lock, so that the door is locked, when the lock plunger mechanism moves to a front stroke position, the stroke switch sends out a in-place signal to control the lock plunger driving mechanism and the lock plunger redundant driving mechanism to stop working, and the lock plunger mechanism stops moving.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
