  • Publication number: 20230116243
    Abstract: An electronic lock includes a latch mechanism and a rotation assembly. The rotation assembly includes a rotator, a single sensor and a processor, the rotator can be rotated toward a first direction or a second direction to drive a latch of the latch mechanism to be extended or retracted. The sensor is provided to sense a protrusion, an auxiliary protrusion, a recess and an auxiliary recess of the rotator to output a sensing signal. The processor is electrically connected to the sensor to receive the sensing signal and is provided to distinguish whether an actuation of extension or retraction of the latch is complete according to a potential variation of the sensing signal.

  • Publication number: 20230074135
    Abstract: A method for periodically activating a battery unit applied to an electronic device equipped with the battery unit includes steps as follows. A plurality of intervals are defined, wherein each of the intervals has an initial voltage value and a target voltage value, and the initial voltage value is greater than the target voltage value. An activation strategy for each of the intervals is defined. A voltage value of the battery unit is detected. One of the intervals is selected as a selected interval according to the voltage value of the battery unit, wherein the voltage value of the battery unit is less than or equal to the initial voltage value of the selected interval, and the voltage value of the battery unit is greater than the target voltage value of the selected interval. The battery unit is activated according to the activation strategy of the selected interval.

  • Publication number: 20220341215
    Abstract: A lock device includes a shell, a bolt mechanism, a magnetic member, and a magnetic sensing module. The magnetic member is movable with the bolt mechanism. When the bolt mechanism is moved between a locking position and an unlocking position, the magnetic sensing module senses a magnetic force variation of the magnetic member. The lock device further includes a magnetic force generation member disposed on a wall. When a door located at a door-closed position with the bolt mechanism being moved to the locking position is shaken relative to the wall, the magnetic sensing module senses a magnetic force variation of the magnetic force generation member.

  • Publication number: 20210348418
    Abstract: The installation kit for an electric lock includes a second lock having a rotary part. The rotary part includes a second shaft. A sleeve is driven by the rotary part and includes a passage which forms an opening formed to one end of the sleeve. A latch bolt includes an operation portion. A first lock includes a first shaft which is engaged with the operation portion so as to lock or unlock the latch bolt. The first shaft of the first lock is engaged with the passage of the sleeve and is co-rotated with the sleeve. The opening is a straight linear-shaped opening, a rectangular-shaped opening so as to be cooperated with the first lock. The second lock can be replaced a new one and operates the first lock and the latch bolt by the rotary part of the second lock.
