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: A deadbolt lock device includes a housing having an inner case covered by an outer case, and an adaptor connected to the inner case. The inner case has an annular flange projecting inwardly from an open end thereof in a direction toward the adaptor, and an annular rib projecting transversely from the annular flange. The annular rib defines a through hole receiving a key-operated lock unit. The annular rib has an annular edge surrounding the lock unit and extends inclinedly from the juncture of the annular rib and the annular flange to the annular edge along directions inclining toward the open end. The annular rib is inclined with respect to a plane intersecting perpendicularly an axis of the lock case. The inclined annular rib provides an increased resistance to destructive forces.

Abstract: A lock core cylinder includes a key plug having a first pin hole, a plug case receiving the key plug and having a notch, and a ring sleeved around the key plug adjacent to the plug case, and having a lug projecting axially and forwardly and extending into the notch, a second pin hole formed in the lug, and a radially and outwardly projecting protrusion movable between an engaging position and a disengaging position and engageable with a lock housing that receives the lock core cylinder.
