A damper assembly for a hinge includes a damper unit (10) with a piston arranged to be moveable over a working stroke within a cylinder (15) containing damping fluid. The damper unit (10) is mounted on a bracket (11) and retained in position by a housing (12). A mechanism is provided for converting rotational movement of the hinge in at least part of one direction into actuation of the damper unit (10) on its working stroke. The movement converting mechanism is arranged to act on the cylinder (15) at a position substantially outside the range of movement of the piston on its working stroke. The arrangement minimises the transmission of radial forces from the movement of the door to the cylinder (15).

A vehicle door device includes: a braking control unit applying a braking force to a swing door of a vehicle by controlling an operation of a braking device; an action position detection unit detecting an action position of the swing door; and a vertical displacement detection unit detecting a vertical displacement of the swing door. The braking control unit does not execute braking control in a case where the action position of the swing door changes with the vertical displacement exceeding a predetermined gripping operation determination value, even in a case where an execution condition of braking control for applying the braking force is satisfied.

A double sliding-plug door system includes a fixed frame, a sliding-plug rail arranged in the fixed frame, a cross beam, a driving mechanism, a linkage mechanism, a guide locking piece and a limiting mechanism. The driving mechanism has a screw rod and a motor driven nut assembly having a transmission frame, a nut sleeved in the screw rod and a follow-up member fixed in the nut; the nut mounted in the transmission frame, which itself is connected with an active sleeve assembly; the screw rod drives the nut assembly to reciprocate axially along the screw rod.

A vehicle door apparatus is disclosed. The apparatus comprises a door configured to be pivotably mounted to a body structure of a vehicle and a door locator mechanism. The door locator mechanism comprises a plunger and a retraction device. The plunger is configured to be actuated between extended and retracted positions. The retraction device is disposed on the plunger and configured to engage the body structure magnetically. The apparatus further comprises a controller configured to withdraw the plunger to the retracted position while activating the retraction device electromagnetically connecting the plunger to the door.

A foldable electronic device includes a first base, a second base, a hinge, a brake, an object sensor, and a controller. The hinge pivotally connects the first base to the second base. The brake is disposed in the hinge. When the first base is expanded with respect to the second base, the object sensor senses whether an object is placed on the second base. When the object sensor senses that the object is placed on the second base, the object sensor sends out a sensed signal. The controller selectively switches on the brake in response to the sensed signal, so as to restrain a rotating angle formed by the first base and the second base.

A gate opening apparatus includes an external housing, a main chassis, a motor device, a driving rotor, a plurality of guiding rollers, a transmission chain connecting the driving rotor, the guiding rollers and a door gate, and a gate actuating arrangement. The gate actuating arrangement includes a clutching device supported on the main chassis and connected to the motor device, a limit switch assembly coupled to the clutching device, and a control module. The gate opening apparatus is arranged to operate between a power mode and a manual mode. In the power mode, the clutching device is engaged with the driving rotor for driving a movement thereof by the motor device so as to selectively open and close the door gate. In the manual mode, the clutching device is disengaged from the driving rotor so that the driving rotor is adapted for being rotated manually.

An appliance is installed within a cabinet such that the appliance is not visible from outside the cabinet when a cabinet door of the cabinet is closed. The appliance includes a compartment and an appliance door that selectively seals the compartment. A push-to-open system is coupled to the appliance door. The push-to-open system includes an arm, a push latch and a spring. The arm connects the appliance door to the cabinet door, and the push latch selectively locks the arm in a locked position. The spring causes movement of the arm from the locked position to an unlocked position when the push latch is unlocked.

A system includes a door, an external electrical connection electrically coupled to a charge store, an opening assembly including a controller, an actuator, a gear, and an actuator arm. The actuator arm is mechanically coupled to the actuator and removably coupled to the door such that the actuator arm opens or closes the door upon actuation of the actuator and the external electrical connection electrically couples to a mobile robotic power delivery device that includes a battery to provide electrical power to the actuator and the controller.

A vehicle door control device includes a door braking unit configured to brake opening-closing operation of a door in a vehicle; a door forcibly stopping unit configured to forcibly and mechanically stop the opening-closing operation of the door, an obstacle detection unit configured to detect an obstacle that exists around the vehicle or approaches the vehicle; and a control unit configured to operate the door braking unit and further operate the door forcibly stopping unit according to a status of the opening-closing operation of the door when the obstacle detection unit detects the obstacle.

A vehicle door apparatus is disclosed. The apparatus comprises a door configured to be pivotably mounted to a body structure of a vehicle and a door locator mechanism. The door locator mechanism comprises a plunger and a retraction device. The plunger is configured to be actuated between extended and retracted positions. The retraction device is disposed on the plunger and configured to engage the body structure magnetically. The apparatus further comprises a controller configured to withdraw the plunger to the retracted position while activating the retraction device electromagnetically connecting the plunger to the door.
