Patent ID: 10808423

Abstract:
An access control system including a locking assembly and a drive assembly operable to actuate the locking assembly. The drive assembly includes an electromechanical actuator, an energy storage device, and a control system. The electromechanical actuator is operable, upon receiving power, to transition the locking assembly between a locked state and an unlocked state. The energy storage device is electrically coupled to the electromechanical actuator, and is configured to store electrical power from the power supply when the drive assembly is coupled to the power supply. The control system is configured to couple the drive assembly to the power supply in response to a first condition, and to thereafter transmit energy only from the energy storage device to power the electromechanical actuator, based at least in part upon a level of energy stored in the energy storage device. The locking assembly may further include a selectable power off function and a controller disposed within a lock housing and operable to control a state of the locking assembly between locked and unlocked positions. The electromechanical actuator is movable between first and second positions corresponding to the locked and unlocked positions, respectively. The locking assembly may further include a selector switch coupled to the controller to define a desired state of the locking assembly between one of an electrically locked (EL) and an electrically unlocked (EU) state in an electric power off condition.
