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.

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.

Certain aspects of the technology disclosed herein include an apparatus and method for a extending a deadbolt. The electromechanical lock can include a deadbolt extending device disposed between a main housing and a deadbolt. The deadbolt extension device can be used to adapt the electromechanical lock to doors of various sizes. The deadbolt extension device can include another electrical connection and another attachment mechanism for the deadbolt. The another electrical connection can be configured to electrically connect the deadbolt with the main housing. The another attachment mechanism can be configured to attach the deadbolt a pre-defined distance apart from the main housing.

A theft deterrent system for an electronics cabinet includes a handle cover having through-holes dimensioned to align with a through-hole in a handle of the electronics cabinet. The through-holes of the handle cover may be dimensioned to receive a shackle of a lock. The theft deterrent system further includes a shackle cover dimensioned to receive the shackle of the lock. The shackle cover may include an upper tab and a lower tab, each comprising a respective shackle slot therein dimensioned to receive the shackle of the lock.

A lock structure includes a lock housing defining an accommodating cavity and a lock head. An outer end surface of the lock housing defines a through hole communicated with the accommodating cavity. The lock head is movably arranged in the accommodating cavity. An outer end of the lock head is movably arranged in the through hole to stretch out of or retract into the through hole. Operating ports are defined on sides of the lock housing. The operating ports are communicated with the accommodating cavity. The lock head includes a movable piece and a lock tongue piece, the movable piece is arranged in the accommodating cavity. The lock tongue piece passes through the through hole and extends into the accommodating cavity. The lock tongue piece is detachably connected with the movable piece.

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.

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.

An exemplary strike box is configured for use with a lockset including a bolt operable to move in an extending direction and a retracting direction. The strike box includes a housing having an opening sized and configured to receive the bolt, and further includes a bolt-slowing mechanism mounted in the housing. The bolt-slowing mechanism is configured to engage the bolt as the bolt moves in the extending direction, and to exert a force urging the bolt in the retracting direction. The force exerted by the bolt-slowing mechanism slows the extension speed of the bolt, such that the strike box reduces noise generated during such extension.
