An exemplary embodiment provides an electric lock, comprising: (a) a knob; (b) a lock body; (c) a rotatable shaft comprising a rotatable-shaft front end and an opposing rotatable-shaft rear end, wherein the rotatable-shaft rear end is fixedly connected to the lock body to control a locking and unlocking of the lock body; (d) a gear assembly comprising a gear and a movable piece with a common axis center; and (e) a motor assembly for driving the gear to rotate. The knob and the rotatable shaft are connected via the movable piece; the movable piece interacts with the gear via a mechanical barrier, such that electrically driving the gear by the motor assembly causes the movable piece to rotate; and the movable piece can pass over the mechanical barrier when a sufficient rotational force is applied to the knob, such that the movable piece is free to rotate relative to the gear, thereby allowing a user to manually control the locking and unlocking of the lock body. In some exemplary embodiments, the provided design of the electric lock structure significantly improves the safety of the electric lock.

Apparatus for unlocking and locking a lock (1′) enabling access to protected areas. The apparatus comprises a housing (5) with a housing interior (64).

A battery cell (9) extends in the housing interior (64) and is in partially surrounding relation of the motor (10). The battery cell is in operative electrical connection with the motor (10). In cross section, the battery cell (9) includes at least two points (34) and (36) such that a line segment (32) joining these two points passes through the motor (10).

A transmission structure of a rotary shaft of an electronic lock contains: a drive unit which includes a holding plate, a motor, a worm, and a driven wheel. The holding plate includes an externally threaded portion and a fixing orifice. The driven wheel includes an internally threaded orifice, two protrusions, two flat zones, two arcuate fringes, and a tooth section. The transmission unit includes a guide element, a movable element, a resilient element, a retainer, and an acting element. The guiding element has a central orifice, the movable element has a guiding orifice, and the acting element has a slidable post. The frame includes a defining orifice and is welded with the holding plate. The connection seat is received in the defining orifice and includes a retaining portion. After the connection seat is received in the defining orifice, the retaining portion is engaged with a fastening ring.

The present invention relates to an electronic lock. The electronic lock includes a turn piece coupled with a cylinder connecting spindle; an electric motor connected with a first bevel gear; and a dislocation transmission mechanism including a first dislocation member coupled with the turn piece and the cylinder connecting spindle and having an arc opening, and a second dislocation member engaged with the first bevel gear and having a protrusion, in which the protrusion is configured to extend into the arc opening, such that when the protrusion is engaged with either a first engaging portion or a second engaging portion at two ends of the arc opening, the first dislocation member is driven by the second dislocation member, and when the first dislocation member is in motion within a void range defined by the arc opening, the first dislocation member fails to drive the second dislocation member.

An electronic lockset assembly is configured to determine whether or not a door is open or closed before the lockset actuates a bolt. In one aspect, a wireless electronic lockset is disclosed. The wireless electronic lockset includes a processing unit, a bolt movable between a locked position and an unlocked position, a motor actuatable by the processing unit to move the bolt between the locked and unlocked positions, and a sensor communicatively connected to the processing unit and configured to detect air pressure. The processing unit is configured to execute instructions to receive, from the sensor, air pressure signals, and determine whether a door is closed based at least in part on a change in the air pressure reflected in the air pressure signals.

An electronic door lock includes a motor having a stator and a rotor that rotates relative to the stator. The rotor is configured to rotate a spindle operatively coupled to a deadbolt lock at a 1:1 drive ratio therewith. The spindle is engaged with the deadbolt lock to cause extension and retraction with rotation of the spindle

A lock state monitoring apparatus, a method, a lock driving apparatus and a lock assembly. The lock state monitoring apparatus includes: a rheostat and a first load, where a movable contact end of the rheostat is connected with a first end of the first load, and a first fixed end of the rheostat and a second end of the first load are configured to bear a first voltage; the movable contact end of the rheostat is configured to be connected with an output axis of a drive motor in the lock; the first fixed end and the movable contact end of the rheostat, or two ends of the first load, are configured to be connected with a main control board in the lock to output a first voltage signal to the main control board, so that the main control board determines a lock state according to the first voltage signal.

A smart lock for securing a door comprising: a housing mountable to the door; an actuator within the housing configured to actuate a lock mechanism between a locked position and an unlocked position, the lock mechanism including a latch bolt with an angled front face, the latch bolt configured to be retractable against a biasing force provided by a biasing means such that the door is closeable when the lock mechanism is in the locked position; and a receiver within the housing configured to wirelessly receive a signal to control operation of the actuator; a sensor mountable exclusively to the door so as to generate a signal indicative of the door beginning to move; a controller arranged to receive the signal indicative of the door beginning to move, the controller configured to control the actuator to actuate the lock mechanism in response to the signal indicative of the door beginning to move.

An intelligent door lock system is coupled to a door at a dwelling. A first sensor is at the dwelling. The first sensor is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at a door. The lock device is coupled to the first sensor and the lock device includes a bolt. An engine, an energy source and a memory are coupled together. A magnetic sensor provides a reading or measurement used to determine a door open or closed status.

Disclosed is a lock actuation assembly for actuating a lock of a door. Prior to first commanding a motor to rotate a key in the key hole a controller of the lock actuation assembly is configured to: receive an indication that a key holder is disposed to have the key at least partially inserted into the key hole; determine a rotational position of a key holder receptacle relative to a mounting portion of the lock actuation assembly from the indication by a position encoder; and store, in an electronic data storage, the rotational position as an initial insertion/extraction position at which the key is insertable to, and extractable from, the key hole.
