An appliance latch receives a strike when the appliance lid is closed and provides an electrically activated lock holding the lid closed during portions of the wash cycle that might present a hazard. The strike presents two different surfaces to the latch, the first to activate a lock mechanism and the second to activate an anti-tamper switch before the appliance may be actuated thereby reducing the risk of tampering.

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.

A modular electronic deadbolt includes a bolt module having a first housing defining a first longitudinal axis, a motor disposed in the first housing, and a deadbolt configured to be linearly moveable in relation to the first housing along the first longitudinal axis by the motor. The modular electronic deadbolt also includes a battery module configured to be operatively coupled to the bolt module. The battery module includes a second housing configured to receive a power source, and a face plate coupled to the second housing. The faceplate defines a second longitudinal axis and includes an extension that extends along the second longitudinal axis. The extension is configured to removably couple the bolt module to the battery module such that the first longitudinal axis is substantially orthogonal to the second longitudinal axis.

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.

Mechanically or electromechanically positioning a deadbolt used to lock or unlock a door is disclosed. An electromechanical lock can include a deadbolt to be positioned to lock or unlock a door. The deadbolt can be mechanically positioned based on the rotation of a paddle of the electromechanical lock or electromechanically positioned via a motor being turned on to position the deadbolt. A disengagement mechanism can disengage an engagement cog from a worm gear hub of a gear train of the motor upon the mechanical positioning, but remain engaged upon the electromechanical positioning.

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 invention relates to a motor vehicle door lock, comprising a locking mechanism, an electric drive, a locking unit and a coupling lever, said coupling lever acting on the locking unit. The coupling lever can be actuated by the electric drive counter to the force of the spring. The locking unit has a control contour, the coupling lever cooperating with said control contour.

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.

A modular surface mounted electric strike system is provided. The system comprises a universal base plate having first and second sides, each having first and second mounting points. Each electric strike module includes a header, a keeper assembly, and an actuator assembly configured for moving between a keeper blocking mode and a second mode. When the first and second latches are separated a first distance, the first and second electric strike modules are attached to the first mounting locations on the respective first and second sides of the base plate. When the first and second latches are separated a second distance, the first electric strike module is attached to the second mounting location on either the first or second sides of the base plate, and the second electric strike module is attached to the second mounting location on the other of the first or second side of the base plate.

Provided is a locking/unlocking device that accurately detects an opening/closing state of an opening/closing device and optimizes timing to lock or unlock. The locking/unlocking device includes a drive unit that drives a lock mechanism of the opening/closing device, a magnetic detection unit that detects a change in a magnetic field based on a change in the relative position between a movable section and a fixed section of the opening/closing device, and a control unit that determines an open/closed state of the opening/closing device on the basis of the change in the magnetic field detected by the magnetic detection unit and activates the drive unit to lock or unlock the lock mechanism on the basis of the open/closed state.
