Fingerprint recognition cabinet lock

Abstract

The invention discloses a fingerprint recognition cabinet lock which comprises a lock shell assembly, a fingerprint recognition assembly, a drive assembly, a control assembly and a power assembly. Thelock shell assembly comprises a basic shell, a bottom plate and panels. The panels are packaged on the two sides of the basic shell. The upper portion of the basic shell penetrates through the panelto be provided with a lock barrel. The fingerprint recognition module comprises a fingerprint collection sensor and a light guide ring. The drive assembly comprises a drive motor and a transmission assembly. The drive motor is in engaged connection with a transmission rod through a gear arranged on a shaft of the drive motor. A controller, a storer and an input and output port are arranged on theupper portion of a master control circuit board. The power assembly is electrically connected with the control assembly. The fingerprint recognition cabinet lock is small in size, simple in structureand easy to mount, the phenomena of motor stalling and shutdown can be prevented from being generated to the lock, the battery replacement possibility can be reduced, the insufficient battery electricquantity is handled with through simple operation, and high popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a fingerprint identification cabinet lock. Background technique [0002] At present, most of the cabinet locks used for bags, bookcases, wardrobes, drawers, etc. on the market are mainly mechanical locks and electronic locks, and electronic locks include coded locks, which can be verified and unlocked through wireless communication methods such as wifi, mobile cellular network, and Bluetooth. A common problem in these locks is that they need to keep the unlocking conditions specially. Mechanical locks need to keep keys, combination locks and wireless verification locks need to remember passwords, keys and passwords are the unlocking conditions, once the unlocking conditions are lost or forgotten, it will cause great trouble to unlock. [0003] For electronic locks that use batteries as power sources and are driven by motors, most of the existing technologies control the operating ...

Problems solved by technology

Mechanical locks need to keep keys, combination locks and wireless verification locks need to remember passwords, keys and passwords are the unlocking conditions, once the unlocking conditions are lost or forgotten, it will cause great trouble to unlock

[0003] For electronic locks that use batteries as power sources and are driven by motors, most of the existing technologies control the operating state of the motor by setting sensors, travel switches or monitoring the number of motor revolutions, and feeding back the state of the lock through electrical signals. The control structure is relatively complicated. ;When the battery power is low, it is difficult to ensure the accuracy of the electrical signal transmission, and the motor drive can make the lock bolt in place; through the electrical signal feedback status, it is also easy to maintain the torque output of the motor when the lock bolt has moved in place Due to the inability to smoothly drive the transmission module connected to the deadbolt, the phenomenon of motor stalling and dullness will be caused, which will affect the operating life of the motor and even affect the normal use of the electronic lock. Most of the electronic locks in the prior art use batteries as power. Ordinary batteries for permanent use, the battery volume is large, resulting in a large volume of electronic locks, which does not meet the market demand for cabinet locks that need to be as small as possible; when the battery power is low or over-discharged, the battery needs to be replaced after unlocking, and the battery replacement process is more complicated. , it may even happen that the lock cannot be unlocked due to insufficient battery power if it is not used for a long time, and the user experience is poor

Most of the electronic locks in the prior art adopt a split structure, the installation is complicated, the reliability and security are insufficient, and the user's experience in unlocking is not good, and it needs to be equipped with an external key. It is not easy to promote the product and increase the customer base.
