Disclosed are embodiments of a tapered bolt receiver for a door lock to accommodate misalignment, between a deadbolt mounted to a door, and an opposing jamb. The tapered bolt receiver can be configured to accommodate misalignment for a deadbolt having a non-tapered bolt, such as for an electromechanical smart lock having a battery stored within a battery compartment that is integrated with an enhanced bolt. Also disclosed are embodiments of a deadbolt plate pivot assembly that is pivotably mountable to a corresponding deadbolt assembly to define a plate pivot system, to accommodate a beveled door edge. An illustrative embodiment of the deadbolt plate pivot assembly includes opposing plate that captures a hinge assembly, which can include plastic plate hinges, which serve to locate the deadbolt plate pivot assembly with respect to a corresponding bolt housing, and can provide a spring force and/or constant torque when mounted to a beveled door.

The disclosure provides a lock with a radially extending cam that can be pivoted electrically or manually by a key. The lock resides in a housing for ease of manufacture and reduction of space, for use, as an example, as a replacement or retrofit for an existing manual cam lock. The cam extends transversely to a first axis and is manually rotatable by a key about the first axis. The cam is also rotatable about a second axis parallel to the first axis by an electrical signal to a motor or a linear actuator connected to a cam mechanism body.

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 driving force transmission mechanism is provided which includes an input switching clutch configured to selectively transmit, to the output shaft (output member), either one of the rotationally driving force applied to the electrically driven input gear (first input member) and the rotationally driving force applied to the manually driven input shaft (second input shaft). A speed reducer having a simple structure and having no self-locking function is attached to the input side of the electrically driven input gear so that the rotation torque necessary to rotate the electrically driven input gear through the input switching clutch from the manually driven input shaft is larger than the rotation torque necessary to rotate the output shaft through the input switching clutch from the manually driven input shaft.

Certain aspects of the technology disclosed herein include an apparatus and method for electrically and mechanically connecting a deadbolt to a main housing of a lock. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door while receiving electrical energy from an energy storage device disposed in the deadbolt. The energy storage device disposed in the deadbolt can be proximate to one or more electrical contacts electrically connected to one or more components in the main housing via conductive components of a bolt carriage. The bolt carriage includes a groove attachable to a male detent connector attached to the deadbolt. The groove in the bolt carriage provides a mechanical connection to the deadbolt and also aligns pogo pins with electrical components of the bolt carriage to enable electrical transmission from the deadbolt to the main housing.

The disclosure provides a lock with a radially extending cam that can be pivoted electrically or manually by a key. The lock resides in a housing for ease of manufacture and reduction of space, for use, as an example, as a replacement or retrofit for an existing manual cam lock. The cam extends transversely to a first axis and is manually rotatable by a key about the first axis. The cam is also rotatable about a second axis parallel to the first axis by an electrical signal to a motor or a linear actuator connected to a cam mechanism body.

Determining a position of a deadbolt used to lock and unlock a door is disclosed. An electromechanical lock can include a deadbolt that can retract or extend along a linear path as the door is to be locked and unlocked. A sensor such as an accelerometer can rotate along a non-linear path as the deadbolt moves along a linear path. The accelerometer can determine a gravity vector that can be indicative of a position of the accelerometer along the non-linear path. A controller can then determine a position of the deadbolt based on the gravity vector.

A latching system and method are configured to selectively latch and unlatch a first component in relation to a second component. The latching system and method include an actuator, a first coupler secured to the actuator, a latch, and a second coupler secured to the latch. The first coupler is configured to couple to the second coupler to couple the actuator to the latch. The first coupler is configured to uncouple from the second coupler to uncouple the actuator from the latch in response to the latch being manually operated.

There is provided an electrical key lock device, including a second gear configured to rotate by driving power received from a motor, a first gear configured to transfer the driving power, received through the rotation of the second gear, to an external rotational element, and a third gear arranged between the second gear and the first gear and configured to transfer the driving power generated by the motor to the first gear. The third gear enables switching between closing and opening of a transfer path of the driving power between the second gear and the first gear.

A gear system for a deadbolt lock including a planetary gear set. The gear system may include a thumb turn direct-drive system to bypass a motor, and an overload protection system to prevent damage to the motor in the event of a jam.
