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.

The invention concerns a lock unit, comprising a lock assembly having a locking element and a drive receiving portion operatively associated with the locking element and a drive unit connected to the lock assembly, the drive unit having a motor and being configured to move the locking element of the lock assembly from a locked position to an unlocked position, the drive unit including a driving element that interfaces with the drive receiving portion of the lock assembly to move the locking element from the locked position to the unlocked position, wherein the drive unit is selectively separable from the lock assembly. The invention facilitates fitment of the lock assembly in position, provides a more compact and secure solution, and assists in regard to maintenance.

An apparatus and method for storing energy in a electromechanical lock. The electromechanical lock can include a main housing and a deadbolt. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door. The deadbolt can have a hollow inner region configured to receive an energy storage device. The energy storage device within the deadbolt can be electrically connected to the main housing. The energy storage device can be used to power an actuator and/or accelerometer in the main housing.

An exemplary trim assembly comprises an escutcheon, a drive spindle, a lock mechanism, a cam mechanism, and a driver. The drive spindle is mounted to the escutcheon for rotation about a longitudinal axis. The lock mechanism includes a lock gear movably mounted in the escutcheon. The cam mechanism includes a first cam defined by the escutcheon and a second cam defined by the lock gear. The driver is operable to rotate the lock gear between a first rotational position and a second rotational position. The cam mechanism is configured to longitudinally drive the lock gear from a first longitudinal position to a second longitudinal position as the lock gear rotates from the first rotational position to the second rotational position. Movement of the lock gear between the first longitudinal position and the second longitudinal position transitions the lock mechanism between a locked state and an unlocked state.

A clutch assembly of an electronic cabinet lock includes a cam, a camshaft, a gear disc, a sleeve, a snap ring, and a steel ball. The cam includes a sleeve ring at its inner end and a swing arm at its outer end. The camshaft is sleeved within the sleeve ring by clearance fit, and the sleeve ring is sleeved within the sleeve by clearance fit. The gear disc is sleeved on the outer wall of the sleeve. The steel ball is mounted in a through groove of the side wall of the cam. The steel ball is located between the sleeve and the cam and is tangent to the camshaft. The camshaft is provided with a groove, and the groove allows the steel ball to fall in. The snap ring is engaged in an annular groove of the lower end of the camshaft for restricting the sleeve.

An intelligent lock, overlock, and lock system can be electrically controlled to open and close one or more locks. The lock, lock system, and method may function on a frequency selected to avoid cross talk, which permits numerous locks to function simultaneously on the same central system with little interruption or delay. A lock may be used as an overlock for an existing lock or be a primary lock and may include a pivoting engagement structure that engages a locking mechanism to provide added strength.

An electrically actuated locking mechanism may include a microprocessor for control of the locking mechanism, and the locking mechanism may be used to lock a drawer slide in a closed position. The microprocessor may be in a housing of the locking mechanism, and the microprocessor may command a motor to operate in a first direction to drive lock components to a locked status and command the motor to operate in a second direction to drive the lock components to an unlocked state.

An electronic lock includes a housing, and a locking system within the housing. The locking system includes electronics and a lock. More particularly, the housing contains therein, a controller and at least one electronic input device electrically coupled to the controller, where the controller causes the lock to transition between a locked position to an unlocked position responsive to input from the electronic input device.

A cooler and freezer access control system locks a cooler or freezer when occurrence of an event is detected that requires limiting access to the inside of the cooler or freezer. Examples of such events include the loss of power to the cooler or freezer for a predetermined period of time, the opening of the cooler or freezer door for longer than an allowed time, the loss of functionality of a temperature probe and others. In an embodiment, a service mode is supported wherein the door is left unlocked despite the occurrence of such an event, to allow a stocker or other personnel to leave the cooler or freezer door open while stocking the cooler or freezer with product.

Driven lock systems, fenestration units including the driven lock systems, and methods of operating the driven lock systems are described herein. The driven lock systems as described herein offer a combination of powered or motorized operation in addition to manual operation, with the opportunity for a user to manually switch the lock assembly between its locked and unlocked states as needed. The need for manual operation may arise if, for example, the system loses power, the controls of the system are unavailable, etc.
