Abstract

A keyless lock system includes not only an electromagnetic switch system, a fingerprint identification system, but also included a combination code system though a Bluetooth wireless connection to a smart phone or external device. The electromagnetic switch system can secure a cabinet or any lock. The system can mainly be secured by the force and vibration from outside of cabinet. The fingerprint identification provides the lock device an easy operation without a key. The combination code can be used on the device of the keypad and used on the smartphone though a wireless Bluetooth connection. The combination code can be reset by smart phone or external device. A changeable battery and power supply system will keep the system information at date without losing the memory if the system lost power.

Dependent claims

A lock comprising:

(A) a locking mechanism case body
(B) a locking mechanism switching between a locking position and an unlocking position and including a locking part, a disc and a knob or lever mounted on an axle core;
(C) a locking block connected to the case body with a spring switching between an immobile state in which the locking mechanism is immobile in a locking position and a mobile state in which the locking mechanism is mobile under an external force;
(D) a major electromagnetic switch system controlling the movement of the locking block and including
(1) a body comprising a solenoid and a magnet;
(2) an actuator movable inside the solenoid between a first actuator position in which the locking block is immobilized and a second actuator position in which the locking block is mobile;
(3) an actuator block mounted flexibly on the actuator of the major electromagnetic switch stabilizing the locking blocking and reducing the force from the locking block on the actuator of the major switch;
(E) a minor electromagnetic switch system including
(1) a solenoid body;
(2) a rod movable inside the solenoid;
(3) a stop plate mounted on the case body, and the slot of the stop plate floated on the rod of the minor electromagnetic switch with a spring;
the stop plate is movable between a first plate position in which the actuator of the major electromagnetic switch system is immobilized and a second plate position in which the actuator of the major electromagnetic system is mobile;
(F) a return switch applies a locking signal to the major electromagnetic switch when acted by the disc;
(G) a power source from which the power should be shut off if no operation within a predetermined amount of time.
