An intelligent lock, overlock, and lock system can be electrically controlled to open and close one or more locks. The lock, lock system, and method may function on a frequency selected to avoid cross talk, which permits numerous locks to function simultaneously on the same central system with little interruption or delay. A lock may be used as an overlock for an existing lock or be a primary lock and may include a pivoting engagement structure that engages a locking mechanism to provide added strength.

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 door locking device including a rotary part including a first rotary part and a second rotary part allowed to be changed into a locked state or an unlocked state through rotation; an elastic rotary part rotated by movement of a locking body moved by a key; a cam lever moved by rotation of the elastic rotary part; a clutch pushed and moved by movement of the cam lever; and an interlocking member inserted into the rotary part by movement of the clutch to interlock the first rotary part and the second rotary part is provided.

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 vehicle door latch device includes: a latch body including: a latch secured by a latch shaft on a rear surface side of the latch body, the latch being configured to engage with a striker; a ratchet secured by a ratchet shaft on the rear surface side of the latch body, the ratchet being configured to engage with the latch; and a striker advancing path into which the striker advances relatively; a motor configured to release the ratchet from the latch; and an actuator case provided continuously on top of the latch body, the actuator case being configured to accommodate the motor.

The electronic actuator of an electronic padlock according to the invention is arranged to turn the cam piece (5) to release the latch parts (7) from a locking state and to turn the cam piece (5) to hold the latch parts (7) in the locking state. The cam piece (5) comprises a cover part (5A) and a shaft part (5B). The cover part has a central hole (12) for the shaft part. The shaft part (5B) has a shaft pin (15), which is set into the central hole (12). The shaft part also has a connecting part 19, which is arranged to be in contact with the electronic actuator 4. The cam piece further comprises a spring (9) which is between the shaft pin (15) and the cover part (5A). The spring comprises a first end (9A) and a second end (9B). The first end 9A is arranged to be in contact with the cover part 5A. The second end 9B is arranged to be in contact with the shaft part 5B. The spring is arranged to transmit turning force of the electronic actuator from the shaft pin 15 to the cover part 5A in the direction of said locking state.

A wirelessly-controlled jamb-mounted access control system can include an in-jamb housing, a lock body at least partially inside the housing and rotatable about a first axis between locked and unlocked positions. The first axis can extend parallel to the jamb, and the lock body can include inner and outer sidewalls that define a latch cavity configured to receive a latch tongue of a door. The wirelessly-controlled j amb-mounted access control system can further include an actuator configured to control release of the lock body from the locked position in response to a control signal.

A rim strike assembly includes a strike body, strike jaw, retaining clutch, locking cam, locking clutch, and a solenoid. The strike jaw, retaining clutch, locking cam, and locking clutch are pivotably coupled to the strike body. The strike body and strike jaw define a latch cavity to receive a latch of a door. The strike jaw includes a jaw follower. The strike jaw is pivotable between a release position and a closed position. The retaining clutch engages the jaw follower and includes a retaining follower. The locking cam includes a retaining notch and a locking notch. The retaining follower engages the retaining notch. The locking clutch includes a locking follower that engages the locking notch of the locking cam. The solenoid includes a plunger coupled to the locking clutch such that movement of the plunger rotates the locking clutch from a locked position to an unlocked position.

A latch module incorporated with an automatic opening function and a secure lock function includes a latch, a spring that applies a force to move the latch in a first direction, a drive to move the latch in a second direction, a cam that transmits power of the drive to the latch, and first and second switches that are turned on and off by the cam. The first and second switches are in a first mode in which the two switches are turned on and the latch is disposed at a manual lock position, a second mode in which the first switch is turned on and the second switch is turned off and the latch is disposed at an opening position, a third mode in which the first switch is turned off and the second switch is turned on and the latch is in a secure lock position.

An electronic cylinder lock has a main body. The main body is provided with a rotary cam. A first shaft is connected to the rotary cam. The first shaft has a first engaging portion. The main body is provided with a second shaft. The second shaft has a second engaging portion. A control lever is connected to the second shaft. A driving source is connected to the control lever. The driving source can drive the control lever to pull the second shaft to approach the first shaft, so that the second engaging portion is engaged with the first engaging portion, thereby improving the joint stability between the second engaging portion and the first engaging portion.
