Background
Electric automatic door locks have been widely used in some office spaces and hotel rooms. A conventional electric automatic door lock usually uses a position sensing device to provide position information of a door leaf to control a motor to operate for locking. The mechanical structure of the door lock is relatively simple, but a relatively complex information collecting and judging circuit is required, and particularly, continuous power supply is required in use, so that the manufacturing cost and the use cost of the door lock are relatively high.
In the prior art, chinese patent document CN1851214A discloses an electric motor lock, which includes a lock body, a lock catch, a lock tongue, a key, a knob, and a micro-motor, wherein the lock body is composed of a main housing and a cover, the knob penetrates through the cover and extends into the lock body, the lock is driven by the micro-motor, a pinion drives a large gear, a shift lever shaft drives a connecting rod, the connecting rod drives the lock tongue, the lock tongue retracts to a proper position, a card is inserted into a groove specially provided for the turntable under the action of a pagoda spring to make the turntable not rotate, thereby achieving the purpose of opening the door; the magnetic steel A is clamped in the inner hole of the step of the push rod, the magnetic steel B is fixed in the lock catch and is opposite to the center of the magnetic steel A and homopolar, under the mutually repulsive acting force, the push rod is pushed to touch the card again to enable the pagoda spring to contract, the card is pulled out from the groove specially arranged for the rotary disc, and the door is automatically locked under the action of the torsion spring. However, in the prior art, when the door leaf does not leave the door frame, the mutual repulsion effect of the magnetic steel B and the magnetic steel a enables the lock tongue to retract in place in the door opening process, and the clamping piece cannot be inserted into the groove specially designed for the turntable under the action of the pagoda spring. But the motor is required to keep the force application state, the bolt can not be retracted to the right position until the door leaf leaves the door frame, and the clamping piece is inserted into the groove specially designed for the turntable under the action of the pagoda spring, so that the turntable can not rotate. As is known, in the case that the driven member cannot move, the state that the motor keeps applying force is actually an overload state, and the long-term overload operation of the motor is a damage to the motor, which reduces the service life of the motor.
Chinese patent document CN202970131U discloses a lock-out control mechanism of an automatic door lock, which includes a latch member, a trigger assembly disposed in an accommodating space in the lock case or the latch, and a locking assembly acting between the lock case and the latch member for locking. The trigger assembly comprises a contact rod, one end of the contact rod penetrates through the front panel of the lock shell to form an actuating head, the other end of the contact rod is a trigger part, the actuating head moves to a trigger effective position or a trigger ineffective position under the action of acting force on the door frame in the opposite direction of closing or opening the door, and the locking assembly releases the locking of the lock tongue component to enable the lock tongue to automatically pop out to lock the door or keep the lock tongue in a locked state.
The locking control mechanism of the automatic door lock disclosed in the chinese patent document CN202970131U is applied to a mechanism composed of magnetic steel, a push rod, a spring and a card in the motor lock disclosed in the chinese patent document CN1851214A, and can solve the above technical problems in the technical scheme disclosed in the chinese patent document CN 1851214A. However, in the actual manufacturing process, since the space inside the lock case is very small, the structure added to the lock-out control mechanism in the limited space requires small and delicate parts, so that the processing precision and requirements of the corresponding parts are greatly improved, and in addition, the assembly of many small parts is laborious.
