【Background technique】

With the continuous improvement of people's living standards, intelligent electronic safes have gradually entered people's lives and work, and people have put forward higher and higher requirements for the safety and reliability of safes. The traditional electronic safe cabinet lock consists of a motor, a transmission mechanism, a deadbolt and a mandrel. The transmission ratio between the motor and the transmission mechanism is not high, resulting in a small output force at the deadbolt end. Because the mandrel of the safe cabinet is heavy, the output The strength requirements of the output end are relatively high. Although the lock bolt and mandrel can be driven in normal use, when the safe cabinet is deformed, the cabinet body and the lock bolt or mandrel have contact friction, or even have a tendency to lock, the strength of the output end It is not enough to drive the bolt and the mandrel to withdraw from the pin hole to unlock; secondly, the motor and the transmission mechanism in the traditional electronic safe cabinet lock adopt a worm gear transmission, so that the motor can drive the transmission mechanism through the worm gear, but the transmission mechanism cannot Drive the motor to rotate, there is a self-locking situation, and a spare key unlocking device cannot be provided. When the motor fails or the control part of the control motor fails, and the motor cannot work normally, the locking or unlocking action cannot be performed, which has great disadvantages.
