Abstract: An electronic lock includes a deadbolt, a driver mechanism, a transmission mechanism and a control mechanism. The transmission mechanism includes a transmission gear that is driven by the driver mechanism to rotate, a resilient unit that is mounted to and co-rotatable with the transmission gear, and a rotary member that is operable to rotate relative to the transmission gear between a locking position and an unlocking position, and that is connected to the deadbolt. The control mechanism is connected to the rotary member, and ceases operation of the driver mechanism when detecting that the rotary member has been rotated to one of the locking and unlocking positions.

Abstract: A bi-directional electronic lock device includes a lock mechanism and a control unit. The control unit includes a position determining component driven by the lock mechanism to rotate, a sensor configured to generate a specific sensing signal for each of three positions with respect to the position determining component, a direction determining module that actuates the lock mechanism to move from a locked state toward an unlocked state, and that generates a directional signal based on the sensing signals, and a control module that is configured to, in response to receipt of the directional signal, set the lock mechanism, based on the directional signal, to operate in one of a left setting and a right setting.

Abstract: An electronic lock includes an input apparatus. The input apparatus includes a keypad module and a processor module. The keypad module includes plural button devices arranged in plural rows and in plural columns. The processor module includes a signal-processing unit configured to, when operating in a work mode, repeatedly perform an emission process of inputting a detection signal to each column of button devices, and repeatedly perform a scan process to detect, for each row of button devices, the detection signal outputted from any row of button devices. The detection signal includes a pulse wave composed of plural pulses. The signal-processing unit is further configured to generate and output an input signal corresponding to one of the button devices when detecting the detection signal.

Abstract: An electronic lock includes an electric locking unit, a touch panel, and a control module. The control module stores a plurality of touch condition sets which are related to human contact. The control module executes an input scan operation on each touch switch of the touch panel, charges a self capacitor with a scan signal, and charges a mutual capacitor with a driving signal. The control module determines whether an electric change conforms with any one of the touch conditions. Through a structural design of the touch panel and a scan function design of the control module, the electronic lock can more accurately determine whether the touch panel is operated by human touch and can also normally operate in a humid environment.

Abstract: An electronic lock includes a lock mechanism operable to change a state thereof between a lock state and an unlock state, and an electric control device including a motor module and a controller. The motor module is electrically operable to perform a lock operation or an unlock operation on the lock mechanism. The controller is configured to, when the lock mechanism changes the state thereof, determine whether a driving current provided to drive operation of the motor module satisfies a predetermined current condition. The controller stops driving operation of the motor module after determining at least that the driving current satisfies the predetermined current condition.

Abstract: In a door lock, a locking mechanism includes an outer wheel, an inner wheel disposed inside the outer wheel and operable to rotate relative to the outer wheel, a clutch member disposed in the inner wheel and normally biased to radially extend from the inner wheel into the outer wheel to interengage the inner and outer wheels, and an arm plate sleeved around the inner wheel. When the inner wheel rotates in a first direction, the arm plate is driven by the inner wheel to actuate the deadbolt. When the inner and outer wheels are interengaged, the inner wheel drives the outer wheel by rotating in a second direction. When the inner wheel disengages from the outer wheel, rotation of the inner wheel in the first or second direction is idle relative to the outer wheel.

Abstract: A method of mounting an electronic door lock on a door includes: a manual operation to rotate a protrusion of a rotational actuator to initially press a switch; and an operating procedure implemented by the electronic lock for determining a correct mounting direction of the electronic door lock. The operating procedure includes controlling, in response to a signal sent by the switch that is initially pressed, a driving unit to rotate the protrusion in a direction from the initially pressed switch to the other initially un-pressed switch and to drive a latch to move from an unlatched position toward a latched position, followed by stopping and subsequently controlling the driving unit to rotate the protrusion in a reverse direction and to drive the latch to move toward the unlatched position.
