The present disclosure relates to an automatic locking device, including a locking base and a locking tongue. The locking tongue is slidably mounted on the locking base in an elastically resettable manner. The automatic locking device further includes a force assisting rod. The force assisting rod is rotatably mounted to the locking tongue. The force assisting rod is provided with a first force assisting surface and a second force assisting surface. The automatic locking device can lock the locking point normally and automatically when the locking point moves down.

An apparatus including a chassis assembly having a housing, a spindle rotatably mounted to the housing, a spring collar rotatably mounted to the housing, a first biasing element rotationally urging the spindle toward a spindle home position, and a second biasing element rotationally urging the spring collar toward a spring collar home position. The apparatus may further include a handle mounted on the chassis such that the chassis biases the handle to a handle home position with a return torque. The handle is engaged with the spindle such that the first biasing element contributes to the return torque. In certain embodiments, the handle may further be engaged with the spring collar such that the second biasing element contributes to the return torque.

A wearable electronic device including a body having a first locking recess, a wearable element having a second locking recess and a locking structure disposed in one of the first and the second locking recesses and including a pressing element and a locking element connected with each other is provided. The locking element is adapted to lock another one of the first locking recess and the second locking recess to assemble the body and the wearable element together, and the pressing element is adapted to receive an external force and move along a vertical axial direction into the first locking recess or the second locking recess which the locking structure is located, and drive the locking element to move along a horizontal axial direction into the first locking recess or the second locking recess which the locking structure is located, so as to unlock the body and the wearable element.

A latch including a housing having side members each having an elongated slot, a bolt mounted rotatably to the housing and positioned between the side members of the housing, an adjustment mechanism, and a pin and roller positioned slidably within the elongated slots of the side members of the housing. The adjustment mechanism includes a compression spring, a central cap for receiving the pin and roller therethrough, and a nut for adjusting the load on the compression spring. The bolt is moveable between a first, closed position, in which the pin and roller are engaged with the bolt, and a second open position, in which the pin and roller are disengaged from the bolt. The latch can be opened automatically when a defined load, as adjusted by the adjustment mechanism, is provided on the bolt to disengage the pin and roller from the bolt.

An exemplary electronic actuator assembly is configured for use with a pushbar assembly having a drive assembly operable to retract a latchbolt, and includes an input shaft, a motor, and a boost spring. The motor has a retracting state in which the motor drives the input shaft from a proximal position to a distal position, a holding state in which the motor exerts a holding force to retain the input shaft in the distal position, and a releasing state in which the motor exerts a residual force that resists movement of the input shaft. The boost spring exerts a boost force urging the input shaft in the proximal direction to at least partially counteract the residual force.

The present disclosure provides an electro-mechanical lock assembly which illustratively includes a motor, a gear, a driver, a torque member, a housing, and a bezel. The motor is operable upon selective input. The motor is also coupled to the driver to engage both the gear and the housing when the motor is in operation. The bezel is attached to the gear such that when the driver is engaged with both the gear and the housing, manual rotation of the bezel will rotate the housing. The housing is attached to the torque member which is configured to move a latch such that when the bezel rotates the latch is moved.

A latch including a housing having side members each having an elongated slot, a bolt mounted rotatably to the housing and positioned between the side members of the housing, a trigger mounted rotatably to the housing, and a pin and roller positioned slidably within the elongated slots of the side members of the housing. The bolt is moveable between a first, closed position and a second open position. The trigger is moveable between a first position, in which the pin and roller are engaged with the bolt when the bolt is in its first position, and a second position, in which the pin and roller are disengaged from the bolt. The latch can be opened automatically when a defined load is provided on the bolt, or manually by depressing the trigger to disengage the pin and roller from the bolt.

An automatic locking device is provided. The automatic locking device includes a locking base and a locking tongue. The locking tongue is slidably mounted on the locking base in an elastically resettable manner. The automatic locking device further includes a force assisting lever. The force assisting lever is rotatably mounted to the locking tongue. The force assisting lever is provided with a first force assisting surface and a second force assisting surface. The automatic locking device is configured to lock the locking point normally and automatically when the locking point moves down.

A door lock, including: a lock bolt, a lock catch assembly, a switching control assembly door lock, and a combination lock assembly. The lock bolt is fixedly connected to the inner side. The lock catch assembly includes a fastening state and a releasing state. When the door is closed, the lock catch assembly is in the fastening state, and the lock bolt is fastened by the lock catch assembly. When the door is closed, the switching control assembly switches the lock catch assembly from the fastening state to the releasing state, during a process of switching, the lock bolt automatically pops out of the lock catch assembly and drives the door to rotate to disengage from the closed state. The switching control assembly includes an unlocking state set to operable and a locking state that prohibits operation. The combination lock assembly controls the switching control assembly to switch.

Aspects disclosed herein relate to electrified locking device assemblies and related methods. In some embodiments, a locking device assembly may include a motorized drive assembly for helping return a locking member to its original position following an incomplete door handle actuation. In some embodiments, the drive assembly may include a motor and spring-loaded actuator, which may be permitted to release energy by transferring the stored energy to a pivotable arm of the locking device assembly. In some embodiments, the motorized drive assembly may include two lock springs, each of which may store energy when compressed between a motor-driven shuttle and a proximal wall.
