Description

Technical Field

[0001] The utility model relates to the technical field of locks, and in particular to a cabinet lock body and a storage cabinet which are unlocked by a motor. Background Art

[0002] With the rapid development of the logistics industry, sending and receiving express parcels has become an indispensable part of people's daily life. However, when delivering parcels, couriers often encounter situations where customers are not at home, which brings great inconvenience to couriers. In order to solve the above problems, many residential areas or communities have installed self-service express lockers for couriers to deliver parcels.

[0003] The express cabinet locks in the prior art generally use electromagnetic drive or motor drive to perform switch lock operations. The express cabinet locks using motor drive mainly realize unlocking operation by driving the thread movement driven by the motor. However, the screw-driven unlocking method has high requirements on the stability of the motor's output power. In the usage scenario with lower temperature, the output power of the motor will be reduced, resulting in insufficient rotation angle of the screw, resulting in the inability to unlock. At the same time, due to the strong limiting effect of the thread on the screw, if the output parameters of the motor are adjusted too large at the beginning, the service life of the motor will be reduced to a certain extent. Therefore, a cabinet lock body and a storage cabinet using motor-driven unlocking are provided to solve the problem that the motor-driven screw movement sometimes cannot unlock normally at low temperatures.
