A door hinge apparatus of a vehicle may include a slide unit including a slide body and a main slider where the slide body is provided on one side of a vehicle body corresponding to an end portion of a door in the vehicle and the main slider is movable in a width direction of the vehicle with respect to the slide body, and a door hinge bracket engaged with the end portion of the door and operably coupled to the main slider.

A system for exerting torque on a shaft includes: a spring assembly having; a spring; a companion member to the spring, wherein at least one of the spring and the companion member is in compression and the other of the spring and companion member is in tension; connecting structure for transmitting a force associated with the spring outside of the gear assembly; and a gear train for connecting the connecting structure to the shaft to apply torque to the shaft. A method of exerting torque on a shaft includes: arranging a plurality of spring assemblies arranged in an array around the shaft, each spring assembly having; a spring; connecting structure for transmitting a force associated with the spring; attaching a gear train to the connecting structure; and configuring the gear train to apply the force associated with the spring to the shaft in the form of torque on the shaft.

A drive arrangement configured to pivot a tailgate pivotally coupled to a vehicle body, between an open position and a closed position and including a freewheel mechanism, a drive shaft, and a motor. The freewheel mechanism may be rotatably coupled to the vehicle body and defining an opening provided with an inner periphery that includes a first cam element and a second cam element. The drive shaft may be fixed to the vehicle body and extending into the opening. The drive shaft may define an outer periphery that includes a third cam element and a fourth cam element. A motor may be coupled to the freewheel mechanism and may be configured to rotate the freewheel mechanism so that the first cam element engages the third cam element to pivot the tailgate from the closed position towards the open position.

An unmanned aerial vehicle airport, an unmanned aerial vehicle system, a tour inspection system and an unmanned aerial vehicle cruise system. The unmanned aerial vehicle airport comprises a support base, a parking apron, a protective cover and a protective cover opening and closing driving device. The parking apron is installed on the top of the support base; the protective cover covers the top of the apron; the protective cover opening and closing driving device is installed between the support base and the protective cover, and the protective cover opening and closing driving device is configured to cause a bar linkage mechanism to drive the protective cover to switch between an open position and a closed position. The unmanned aerial vehicle airport is provided with the protective cover for the parking apron. If the protective cover is open, the unmanned aerial vehicle is parked on the parking apron, and takes off from the parking apron.

The motorized drive according to the application is particularly suitable for auxiliary or emergency drives and is configured to open or close a wing of a barrier such as a door. The motorized drive includes a motor and a reduction unit through which the motor can open or close the wing, an auxiliary motor including a helical spring which is able to absorb mechanical energy during the opening of the wing and release it during the closing of the same, a reduction unit connecting the auxiliary motor to the wing. A first and a second toothed profile realize a gear with a variable transmission ratio. The first and/or the second toothed profile form at least one toothing having a pitch profile which is substantially non-circular or not formed by a simple arc of a circle or a straight line.

A sliding door for a vehicle, which is applicable to a door portion to which a straight rail is difficult to be applied, may include a door rail mounted in a door which is configured to be closed to a vehicle body in a vertical direction of the vehicle; a vehicle body rail mounted in the vehicle body to which the door is configured to be closed in a longitudinal direction of the vehicle; and a moving arm having one end portion which is movably coupled along the door rail in the vertical direction to open or close the door in a transverse direction of the vehicle body during moving, and the other end portion which is movably coupled along the vehicle body rail in a longitudinal direction to allow the door to be slidingly moved in a longitudinal direction of the vehicle body during moving.

A dimmer mechanism is movable by a motor that is powered by solar-charged supercapacitors between a first configuration, in which the dimmer mechanism blocks little of the interior of a skylight tube to maximize light throughput into a room, and a second configuration, in which the dimmer mechanism blocks more of the interior of a skylight tube to reduce light throughput into the room.

A firearm safe box comprising a housing having sides defining an interior volume and an opening. A container is slidably received in the opening of the housing, the container being movable between a closed position preventing access to the container and an open position allowing access to the container. In this embodiment, the container carries a configured insert adapted to cradle a firearm. A lock mechanism is operative to retain the container in the closed position. An opening mechanism is operative to automatically move the container to the open position when the lock mechanism is released.

A drive assembly for motorized adjustment of an adjusting element of a motor vehicle. The drive assembly includes a drive having a rotational motor unit and a feed gearing drivingly arranged downstream of the motor unit for generating drive movements along a feed gearing axis in first and second adjusting directions, the drive includes a clutch having a first clutch element, rotationally fixed to a driveshaft of the drive, and a second clutch element, rotationally fixed to an output shaft of the drive, in a state in which they are drivingly coupled to one another, the clutch elements transmit rotational movements from the driveshaft to the output shaft, to generate the drive movements of the feed gearing. The clutch is designed as a curved tooth coupling.
