ELECTROMAGNETIC LOCKING DEVICE Russian patent published in 2021 - IPC E05B47/02 

FIELD: security systems.

SUBSTANCE: electromagnetic locking device relates to the field of security technology, in particular to locking devices, locks operating using electromagnetic means, and can be used to lock doors for various purposes, including refrigerator doors and safes. The device contains a housing (12), an electromagnetic lock, a coaxial lock housing (15), a movable crossbar (20) interacting with a ball locking mechanism including a catcher (18) and a retainer (2) made with the possibility of sliding in the lock housing (15), an electromagnet with a winding (14) and a core (11). In the retainer (2) on the side facing the electromagnet, a shunt (16) made of magnetic material, a permanent magnet (22) and a disk (23) made of non-magnetic material are installed sequentially in the order from the electromagnet to the crossbar (20). The device contains an electronic control board (4), made with the possibility of connecting to an autonomous power source and communicating with a remote-control device and supplying voltage to the winding (14) of the lock electromagnet.

EFFECT: invention provides a reduction in energy consumption to ensure the possibility of using low-power autonomous power sources, increasing the faultlessness and reliability of the locking device while reducing the dimensions of the product.
