The present invention relates to an electromechanical lock assembly (1) comprising a lock body (15), a lock core (17), a lock bolt operating member (19), and an electronic access control device. The electromechanical lock assembly further comprises an annular element (27) which is rotatably and axially displaceably mounted on said lock core (17), a coupling device (25) arranged to communicate with said electronic access control device and, upon the insertion of an appropriate key (65) in a key receptacle (37) of the lock core (17), rotationally lock the annular element (27) to the lock core (17), thereby enabling rotation of the lock core (17) in a first direction and thereby enabling unlocking of a lock (3) with said appropriate key (65), and a blocking arrangement (63) arranged to prevent unauthorized unlocking of said lock (3).

The invention discloses an accidental unlocking prevention electronic lock, in particular an accidental unlocking prevention electronic lock in the field of electronic locks. The accidental unlocking prevention electronic lock of the invention comprises a lock cylinder, a control circuit and a clutch sleeve, wherein the control circuit and a key hole are installed in the lock cylinder, and further comprises a transmission system, a power shaft, a clutch cam, a key cam, a key pin and a suspension, wherein the lock cylinder is internally provided with a clamping jaw, a torsion spring and a clamping jaw motor; one end of the clamping jaw is connected with an output shaft of the clamping jaw motor, one end of the torsion spring is fixed in the suspension and the other end thereof is connected with the clamping jaw; the key cam is provided with a limiting groove and the lock cylinder is provided with a limiting pin. The invention has the advantages of high safety and reliability, low power consumption, small volume and strong impact-resistant performance, and can be protected from accidental unlocking even under the conditions of high-speed impact and severe vibration.
