ELECTROMECHANICAL LOCK Russian patent published in 2018 - IPC E05B47/02 

FIELD: locks; electrical equipment.

SUBSTANCE: electromechanical lock relates to the field of security equipment, in particular to the electronic equipment controlled locking devices. Electromechanical lock with the body in the form of U-shaped bracket 1, mounted on the chest body 2 profile, with the motor 4, which shaft 5 is directed into the lock body. On the body bracket 7 second side, coaxially with the motor 4 shaft 5 a hole 8 is made. On the motor 4 shaft 5 a body 10 with the integrated permanent magnet 9 is installed, rotating in the hole 8. On the chest upper door 24 a locking mechanism body in the form of U-shaped bracket 22 is installed, with the threaded bushing 26 installed in the upper door opening and fastened with the nut 27. In the body 22 inner cavity, a rocker 29 is arranged, which is made in the form of the L-shaped bracket 30 with axis 34 in the corner, located in the holes on the body side surfaces. On the bracket external surface a permanent magnet 35 is installed, located opposite to the magnet 9, mounted on the chest body profile 2. At the L-shaped bracket 30 surface 32 end face, an open groove 36 is made, in which a groove 37 is arranged, made at the stem 28 upper end. In the lock open state, the permanent electric drive 9 magnet and the permanent locking mechanism 34 magnet magnetic fields are directed in different directions, and in the closed one, are unidirectionally. In the lock closed state, the magnets 9 and 35 magnetic fields are unidirectional, creating the magnets mutual attraction force. 9 and 35, resulting in the torque generation on the axis 34, the L-shaped bracket 30 end face 32 and the open groove 36 lowering. Stem 28 is lowering blocking the doors 24 and 41 mutual movement. To open the lock, to the motor 4 a voltage is applied, which causes the shaft 5 and the permanent magnet electric drive 9 magnet housing 10 to rotate, until the lock 20 open state sensor tripping moment under the eccentric 19 action, which causes the motor 4 to stop. In this position, the magnets 9 and 35 magnetic fields are unidirectional, the magnets 9 and 35 mutual repulsion causes force the stem 28 to rise. Lock opens, allowing the chest doors 24, 41 movement. To close the lock, to the motor 4 a voltage is applied, causing the shaft 5 and the magnet body 10 to rotate until the lock 21 closed state sensor tripping moment, which causes the motor 4 to stop. During the upper door 24 closing to the initial closed position, the magnets 9 and 35 are aligning, by the magnets 9 and 35 mutual attraction force the stem 28 is moved to the lock locked position.

EFFECT: electromechanical lock can be used for the chests sliding doors locking, to exclude the unauthorized access possibility.
