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.

A rotational shaft (30) is in operative connection with the housing. A motor (10) extends in the housing interior (64), is in operative rotational connection with shaft (30) and is operative to rotate the shaft (30). 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 disclosure relates to a bi-directional overrunning clutch, electronic door locks having bi-directional overrunning clutches, and methods of using the same. In certain embodiments, the electronic door lock includes a first locking mechanism for driving an inner wheel through a first torque to rotate a rotatable shaft to operate a locking device on a door by a user from outside, a second locking mechanism for driving inner wheel through the first torque to operate the locking device from an inside, a third locking mechanism for driving an outer wheel rotatable coaxially around the rotatable shaft through a second torque to operate the locking device electronically, and the bi-directional overrunning clutch. When outer wheel rotates at second torque, inner wheel and rotatable shaft rotate along with outer wheel, and when inner wheel rotates at first torque, outer wheel does not rotate along with inner wheel and rotatable shaft.

Certain aspects of the technology disclosed herein include an apparatus and method for storing energy in a electromechanical lock. The electromechanical lock can include a main housing and a deadbolt. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door. The deadbolt can have a hollow inner region configured to receive an energy storage device. The energy storage device within the deadbolt can be electrically connected to the main housing. The energy storage device can be used to power an actuator and/or accelerometer in the main housing.

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.

Systems and methods for controlling access to a secured space are disclosed. The system includes a locking device having a body having a rotatable locking cam having a locked paddle and an unlocked paddle. The cam is rotatable between a first position and a second position. The body also has a locking pin and a power supply for supplying electrical power to circuit components of the locking device. The locking device also includes a shackle having two arms. One of the two arms has a groove in a bottom portion thereof configured to engage with the locking pin when the shackle is in a closed position. In the first position, the locked paddle of the rotatable locking cam engages the locking pin in the groove. In the second position, the locked paddle of the rotatable locking cam is disengaged from the locking pin.

A lock mechanism having a bolt movable between a thrown position and a retracted position, and a deadbolt assembly includes a sliding deadbolt configured to slide between a locked position in which the sliding deadbolt inhibits retraction of the bolt and an unlocked position. The sliding deadbolt includes a first anti-thrust cam configured to restrain the sliding deadbolt in the locked position, and a release driver arranged such that, when driven, the release driver releases the first anti-thrust cam from restraining the sliding deadbolt in the locked position and slides the deadbolt to the unlocked position.

A manual/automatic dual-purpose clutching structure includes a driving gear assembly, a reversing clutching assembly and a driven gear assembly. The driving gear assembly includes a first gear, a second gear and a driving module, the first gear being coaxially and fixedly connected to the second gear. The reversing clutching assembly includes a reversing gear and a reset spring, the reversing gear is located on one side of and meshes with the second gear. The driven gear assembly includes an output gear which is located on the other side of and does not make contact with the second gear. The reversing gear rotates around a central axis of the second gear under a driving of the driving module to mesh with the output gear. After power of the driving module disappears, the reversing gear is prompted to be disengaged from the output gear under an action of the reset spring.
