An electronic lock includes a control circuit module and an electromagnetic mechanism. The electromagnetic mechanism is electrically connected to the control circuit module, and the electromagnetic mechanism includes a driving member and a magnet. The driving member is configured to be driven by the control circuit module to be located at one of a first position and a second position. When the driving member is not driven by the control circuit module, the driving member is configured to be held at one of the first position and the second position by the magnet.

A latching structure, a household appliance and a control method for the household appliance are provided. The latching structure has a snapping member, a bracket, a limiting member, and a driving assembly. The snapping member is mounted on a door body and has a hook. The bracket is mounted on a housing and has a limiting portion. The hook can penetrate the bracket. The door body is connected to the housing in an openable and closable manner. The limiting member is rotatably mounted to the bracket and can reciprocate between an unlocked position and a locked position. The driving assembly is configured to engage with or disengage from the limiting member. In the unlocked position, the limiting member avoids the hook, and in the locked position, the limiting member is suitable for fitting the hook to limit a position of the hook.

A control device for a push bar latch, comprising: a base frame having a sliding slot; a control connecting rod, the outer end is combined with an unlocking return unit of the push bar latch and the inner end has a positioning pin, the positioning pin is set through the sliding slot; a locking hook, the outer end has a hook portion relative to the positioning pin; an electromagnet, used for holding the inner end section of the locking hook, so let the hook portion enter a hooking state for the positioning pin; and a release element, used to release the hook portion from the hooking state for the positioning pin when the electromagnet is powered off. Whereby the push bar latch has the enter control function.

A locking mechanism is applicable to an intelligent cabinet system having a first object and a second object movable relative to each other. The second object is configured to be located at one of a retracted position, a predetermined extension position and an open position. The locking mechanism includes a locking member and a driving device. The driving device is configured to drive the locking member to move from a first predetermined position to a second predetermined position. When the second object is moved relative to the first object from the retracted position along a direction and when the locking member is located at the second predetermined position, the locking member is configured to block the second object at the predetermined extension position. The predetermined extension position is located between the retracted position and the open position.

An exemplary electronic actuator assembly is configured for use with a pushbar assembly having a drive assembly operable to retract a latchbolt, and includes an input shaft, a motor, and a boost spring. The motor has a retracting state in which the motor drives the input shaft from a proximal position to a distal position, a holding state in which the motor exerts a holding force to retain the input shaft in the distal position, and a releasing state in which the motor exerts a residual force that resists movement of the input shaft. The boost spring exerts a boost force urging the input shaft in the proximal direction to at least partially counteract the residual force.

Disclosed is a miniature smart lock with an anti-prising function, the miniature smart lock comprises a lock shell, and a magnetic rod, a push head, a bolt, a V-shaped push rod, an anti-prising guide slot, and a positioning guide pin, which are mounted in the lock shell, wherein a magnetic coil is mounted surrounding an outer portion of the magnetic rod; a magnetic rod spring is mounted on the magnetic rod on the left side of the magnetic coil; the push head is mounted at the right end of the magnetic rod; the V-shaped push rod is connected to the right end of the push head by means of a V-shaped push rod connection pin; and the V-shaped push rod is movably connected to the bolt by means of an anti-prising pin.

A door lock facility includes a tongue pivotally attached to a housing with a pivot pin, an elbow is rotatably attached to the housing and includes a limb engageable with and detachable from an inner end portion of the tongue, an anchor is rotatably attached to the housing and includes one end portion located close to the tongue for anchoring a free end portion of the limb between the anchor and the tongue, a follower is slidably engaged in an actuator and movable into and out of the actuator for moving the anchor toward and away from the limb, and the actuator includes a rod slidably engaged in the actuator and moveable out of the actuator in order to rotate the elbow relative to the housing and to move the limb of the elbow from the tongue.

A lockable coupling device comprising: a base member releasably connectable to a release member by interengageble portions, the base and release members configurable between coupled and release configurations; a coupling mechanism for permitting actuation between the coupled and release configurations, and including an actuator operatively connected to at least one of the interengageable portions and moveable between a first state permitting engagement of the interengagable portions in the coupled configurations, and a second state releasing engagement of the interengageable portions; a locking mechanism for locking and releasing the coupled configuration, the locking mechanism comprising: an operator input portion operatively connected to a latch portion and configured to: lock the coupled position by causing the latch to engage with the actuator to prevent the actuator moving from the first state to the second state, and unlock the coupled configuration by permitting movement of the actuator from first to second position.

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.
