No matter a latch is extended or retracted at initial state, a method for automatically determining the installation direction of an electronic lock is able to determine the electronic lock is installed on left or right hand door by driving a rotation module to rotate in first or second direction and changing the potential of a signal outputted from a micro switch depending on the rotation module whether touches the micro switch. The method is applicable for more convenient to consumer on installation of the electronic lock.

A smart door lock assembly includes a lock cylinder, a lock cylinder mounting block, a driving motor, and a driving control board. A driving gear is arranged on a movable end of the driving motor. The lock cylinder passes through and is mounted in the lock cylinder mounting block. A driven gear coaxial with the lock cylinder is arranged on the lock cylinder mounting block. The driven gear is driven by the driving gear. The driving control board determines whether an external input unlocking command is right and controls the driving motor to unlock the smart door lock assembly when the external input unlocking command is right. The driving motor has a virtual position in a process of driving the driving gear.

An automated gate for robotic mowers may include at least one door that may be sized to receive a robotic mower, and it can be installed in any fence to enable the mower to move between the yards on its own. The at least one door of an automated gate may provide optional capability to lock when not used by the mower and unlock automatically when the mower gets close. By default, the at least one door may remain unlocked, yet closed, thereby providing a cost-effective solution for customers who do not have to worry about pets. An add-on module may be provided that may add a locking mechanism and triggering mechanism, thereby providing end users with the ability to lock the automated gate completely.

A tool box or tool cabinet (hereafter: “tool box”) is provided with a locking mechanism having a locked condition in which it prevents access to tools within the tool box, and an unlocked condition in which it allows access to tools within the tool box. An electric motor has a rotor, and is provided with a microprocessor and control circuit, coupled to the motor for controlling it. The microprocessor is adapted to receive Bluetooth signals when paired to a user's portable Bluetooth-enabled mobile device, The microprocessor and control circuit are effective, when the user's portable Bluetooth-enabled mobile device is sufficiently close to the control circuit to be detected, to energise the motor to rotate the rotor in a first sense, effective to disable the locking mechanism to allow access to the tools.

A method for retrofitting a roll door lock that enables both manual and remote wireless locking and unlocking of a roll door. More specifically, the retrofitted lock comprises an interior plate with a cylinder lock aperture, a motorhead gear coupled to a motor and rotationally secured within the housing, and a controller functionally coupled to the motor, wherein the controller may be commanded to operate the motor to lock the roll door lock by causing a blocking coupler edge to reduce the diameter of a ball-pin aperture, and unlock the roll door lock by withdrawing the blocking coupler edge.

An electronic lock assembly includes an exterior assembly, an interior assembly, and a latch having a deadbolt movable between an extended position and a retracted position, the latch being movable in response to rotation of a torque blade. The electronic lock includes a motor within the interior assembly and operable to rotate the torque blade, and a control circuit operatively connected to the motor and configured to selectively actuate the motor. A mortise insert includes a battery subassembly electrically connectable to the control circuit.

An electronic lockbox uses a rotary actuator with multiple positions to achieve multiple locking states. Multiple positions of the actuator are detected, using optical sensors. The locking mechanism includes an outer sleeve and an inner cylindrical barrel that are coupled with torsion springs. The lockbox has a shackle and a key bin that are retained by the inner barrel when in the locked state, and the barrel can be rotated to either release the shackle or to release the key bin that typically holds a building's key.

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.

An electric lock includes an input switching clutch for selectively transmitting the electric or manual driving force to the output line. The input switching clutch includes an outer ring that rotates together with an electrically driven input gear, and an inner ring which rotates together with an output gear. Wedge-shaped spaces are defined between the outer ring and the inner ring. Two rollers are mounted in each wedge-shaped space and are biased toward the narrow portions of the wedge-shaped space by a coil spring also mounted in the wedge-shaped space. The input switching clutch further includes an unlocking piece having crossbars inserted at both circumferential ends of the respective wedge-shaped spaces, and coupled to a manually driven input shaft so that its rotation can be transmitted thereto; and a torque transmission mechanism for transmitting the rotation of the manually driven input shaft to the inner ring.

A system for a closure lock comprises a battery-powered remote module with a lock mechanism for operating the lock, the remote module communicating with a base station coupled to a closure controller, the base station able to send lock control signals to the remote module to operate the lock. The module is arranged to have an operation mode and a non-operation mode, power consumption in the non-operation mode being lower than that in the operation mode, and is further configured to switch between the modes based on instructions from the base station. In the non-operation mode, the module maintains a communication link with the base station based on a pre-established synchronisation protocol.

The invention provides reliability against interference between base station and remote module, whilst greatly limiting the power consumption of the remote module.
