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.

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.

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.

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.

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.

A guard locking element (4) actuatable by means of an electric drive (6). By means of the electric drive (6), the guard locking element (4) can be brought into a blocking position such that an actuator (2) of a safety switch is locked by said guard locking element. The guard locking element (4) is connected to the electric drive (6) by means of a coupling (11) such that a rotary motion of the electric drive (6) is converted into a purely translatory motion of the guard locking element (4).

Disclosed are a control method for an electronic lock and an electronic lock based on the control method. The electronic lock has a simple structure, and jointly control a snap hole on the handle with a telescopic body of the electromagnet located on the lock body base and a push rod controlled by the unlock mechanism. The telescopic body of the electromagnet has the characteristics of self-holding function when power off through the first permanent magnet, which not only the hidden danger of illegal unlocking through mechanical structure is solved, but also the power consumption of electronic lock in preventing illegal lock opening can be greatly reduced. The market's technical requirements for electronic locks can be met, and high promotion value can be obtained.
