ELECTROMECHANICAL LOCKING DEVICE Russian patent published in 2022 - IPC E05B47/06 

FIELD: electromechanical energy-independent locking devices.

SUBSTANCE: invention relates to electromechanical energy-independent locking devices powered by a key battery and electronically encoding an unlock code. The device contains an electronic key containing a tail section with protrusions, negative and positive contacts, a housing in which a power source and an electronic board for storing an electronic code are located, and a lock containing a body (14) of the lock, containing a front sleeve (3) and a fixed inner sleeve (1), in which the rotating sleeve (7) of the lock is located, containing the input (2) and end (11) parts, while in the input (2) part there are negative and positive contacts (16) of the lock, and the end part (11) connected to the locking mechanism of the lock through a leash (12), a clutch mechanism containing a slider (4) with a return spring, configured to transfer force to compress the trigger spring (5) of the pin (8) when the tail of the electronic key is inserted into the hole of the fixed inner sleeve (1), and fixing the trigger spring (5) of the pin (8) using the locking mechanism (6), the lock opening mechanism containing the electronic control board (15) is performed with the possibility of identifying the electronic code of the electronic key and transmitting a control signal to the electromagnet (13), which is configured to transfer force to the locking mechanism through the leash (12) due to the transfer of force to the end part (11) of the rotating sleeve (7) of the lock when turning electronic key in the input part (2) of the rotating sleeve (7) of the lock after the identification of the electronic code of the electronic key. The transfer of force to the end part (11) of the rotating sleeve (7) of the lock, connected with the driver (12), is carried out by moving the pin (8) into the hole of the end part (11) of the rotating sleeve (7) of the lock after the electromagnet (13) acts on locking mechanism (6), leading to the release of the trigger spring (5) of the pin (8). The slider (4) and the pin (8) are made with the possibility of returning to their original position due to the accumulated energy of the return spring when the tail part of the electronic key is removed from the hole of the stationary inner sleeve (1).

EFFECT: reduced energy costs when opening and closing the lock.
