Abstract

The present invention discloses a control device and method for unmanned refrigerated cabinet door locks, which relates to the field of electromagnetic lock technology, comprising a door lock. The door lock comprises an installation seat and a cover shell. The surface of the cover shell is provided with bolt holes and the side wall is provided with a lock hook channel. The interior of the cover shell is provided with an opening component and an energy-saving component. When the cabinet door is closed, the electromagnetic push rod is controlled to be powered on to move the moving seat, so that the lock hook at the top of the moving seat locks the lock hook groove of the cabinet door. After the self-locking is completed, the electromagnetic push rod is powered off, and the limit spring is limited by a permanent magnet. At the same time, a copper sheet is set at the end of the electromagnetic push rod to increase the penetration force of the magnet, so that the lock hook remains in a self-locking state and the door lock is reduced The power consumption during this period, when the lock hook enters or extends out of the cover to open and close the door lock, It can be achieved without continuously powering the electromagnetic push rod, thereby improving the service life of the door lock.
