ELECTROMECHANICAL LOCK Russian patent published in 2020 - IPC E05B47/00 

FIELD: locks.

SUBSTANCE: invention relates to locks for doors, safes and cabinets of electromechanical type with remote control. Invention objective is to increase reliability and burglar resistance of the lock during opening and closing. Solving said tasks is achieved in an electromechanical lock comprising a housing, inside which there is a deadbolt, having a working part connected to an electric motor, entering when closing in the opening of the mating plate, characterized in that a reversible DC motor is used, comprising a stator with excitation winding and a rotor, which shaft is connected through a conversion device to a deadbolt, excitation winding is connected by electric wires to control unit, to which low-voltage wires is connected power supply unit, and working section of deadbolt is made with external thread, on mating plate coaxially to hole there is hollow cylinder with internal thread corresponding to external thread of working section of deadbolt. Electromechanical lock can have deadbolt with working part on its entire surface, and conversion device is made inside latch. Conversion device can be made in the form of a gearbox containing a housing, gears and an output shaft connected to a mechanism for conversion of rotary motion into rotary and translational motion. Reduction gear can be made planetary, multi-stage. Control unit may contain a receiving antenna connected to a receiving device, the output of which is connected to the input to the controller, the output of which is connected to the input to the electronic switch, the output of which is connected to the excitation winding. At least one additional power cable with plug connector can be connected to electric wires in front of the power supply unit. Plug connector can be a MicroUSB connector. Controller may contain a central processor and operational and long-term memory units connected to it.

EFFECT: higher reliability and crack resistance of the lock during opening and closing.
