Intelligent door lock structure capable of realizing dual unlocking through fingerprint and password

Abstract

The invention discloses an intelligent door lock structure capable of realizing dual unlocking through a fingerprint and a password. The intelligent door lock structure is provided with a door lock case, the middle of the door lock case penetrates through an installation square shaft, a worm gear and a crescent bolt are connected in the square shaft in parallel in a penetrating mode, an unlockingmotor is arranged on the bottom surface of an inner cavity of a door lock case and meshes with the worm gear through a worm, a fingerprint module is arranged in the front surface of the door lock casein an embedded mode through a handle, a password key set is arranged on the other side of the front surface of the door lock case, a control chip, a motor switch and a battery pack are arranged at the top of the inner cavity of the door lock case, the battery pack is electrically connected to the fingerprint module, the password key set and a control chip through a circuit board, a fingerprint identification module and the password key set are electrically connected to the signal input end of the control chip, and the command output end of the control chip is electrically connected to the unlocking motor through the motor switch. According to the intelligent door lock structure, the unlocking motor sequentially drives the crescent bolt to reverse and retract through the worm gear so as torealize unlocking, so that users, relatives and friends can conveniently come in and go out, and the intelligent door lock structure have a very high practical value.

Description

technical field [0001] The invention relates to an intelligent door lock, in particular to an intelligent door lock with fingerprint unlocking and remote control functions. Background technique [0002] Locks can protect the property safety and personal safety of modern people very well. Traditional locks include a lock body, a lock cylinder and a key. The key is inserted into the lock cylinder and the pins in it interfere with each other, so that the lock cylinder can be locked in the lock body. Turn to unlock. With the improvement of science and technology, people have invented and manufactured many smart locks. These smart locks include fingerprint unlocking, combination locks, etc. to replace traditional keys. However, smart door locks unlocked by fingerprints face the following problems in use, such as For password locks, the password is often forgotten and the smart door cannot be opened. However, the accuracy and reliability of fingerprints are not too high when unlo...
