Electromechanical lock

Abstract

An electromechanical lock includes a lock cylinder having core front and back ends, and an operation knob, coupled with the core front end, enabling a user to rotate the operation knob from an initial knob position so the core front end rotates with the core back end from a locked rear position to a unlocked rear position in an unlocked state of the electromechanical lock. The electromechanical lock further includes a return force mechanism rotating the operation knob towards the initial position after the user first has rotated the operation knob away from the initial knob position and then released the operation knob. The return force mechanism includes first and second magnetic parts coupled with the operation knob and a lock cylinder core body, respectively. An interaction between first and second magnetic force fields of the first and second magnetic parts, respectively, is configured to rotate the operation knob.
