METHOD FOR CONTROLLING AN ELECTROMECHANICAL LOCK AND APPARATUS FOR IMPLEMENTATION THEREOF Russian patent published in 2022 - IPC E05B47/02 

FIELD: locks.

SUBSTANCE: claimed invention relates to electromechanical locks with a bevelled bolt applied in security equipment; in particular, to locking apparatus controlled by electronic means. Electromechanical lock comprises a body (1) shaped as a rectangular box with walls (2-5) and a bottom (6). The bolt (7) with a rod (13) is configured to move in the slot (9) of the front wall (2) and in the hole (16) of the L-shaped bracket (14). A compression spring (17) is installed on the rod (13) of the bolt (7), and a bolt pin (18) is installed on the upper surface of the interior (11) of the bolt (7). An L-shaped magnetic core (19) of an electromagnet coil with a core (20), a horizontal part of the magnetic core (21) and a vertical part of the magnetic core (22) is installed at the bottom (6) of the body (1), wherein protrusions (23), (24) are made at the edges of the upper end surface of said coil. The armature (25) is made in the form of a plate with a liner (31) and a pin (32) installed on the upper surface thereof. The lever (33) is made in the form of a corner with a sleeve (36) and a protrusion (37), and is located on an axle (39), configured for rotational movement. A first permanent magnet (38) is installed on the lateral side of the lever (34), opposite the front wall (2). A plate (42) with a slot for the bolt (43) is installed opposite the electromechanical lock installed on the door, on the door frame, aligned with the slot (9) on the front wall (2); and a second permanent magnet (44) is installed on the side of the plate (42) facing the frame, opposite the first permanent magnet (38). When the door is open, the end of the lateral side of the protrusion (37) of the upper side of the lever (35) adjoins the lateral surface of the bolt pin (18) impacted by the compression spring (17), setting the lateral side (34) of the lever (33) parallel to the front wall (2). The armature (25) herein abuts against the surface (35) of the lever (33) through the liner (31), impacted by the extension spring (30). When the door is being closed, as the slot (9) is aligned with the bolt slot (43), the bolt (7) moves into the bolt slot (43) of the plate (42), impacted by the compression spring (17). When the door is closed, the end of the protrusion (37) adjoins the lateral surface of the bolt pin (18), and the end surface of the lever (33), impacted by the interaction force of the fields of permanent magnets (38), (44), abuts against the lateral surface of the pin (32), and the lower surface of the upper side (35) of the lever (33) abuts against the surface of the liner (31). Voltage is applied to the terminals of the coil (20) in order to open the lock. Impacted by the magnetic forces, the armature (25) is rotated, and the end surface of the upper side (35) of the lever (33) disengages from the side surface of the pin (32). Impacted by the forces of the interaction of the fields of the permanent magnets (38), (44), the lever (35) is rotated, and the end of the protrusion (37) of the upper side of the lever (35) abuts against the lateral surface of the bolt pin (18), thereby moving the bolt (7) with the rod (13) until the end of the rod (13) abuts against the back wall (3) of the body (1). Also proposed is a method for controlling an electromechanical lock.

EFFECT: technical implementation of the method for controlling the lock is simplified, and reliability of operation thereof is increased, due to the lock opening force being generated not by means of a spring compressed by a cocking mechanism when the door is being closed, but by the interaction of magnetic fields of the permanent magnets installed on the lock opening mechanism and on the bar of the lock when the door is closed.
