Abstract:
A power drive system is adapted for a sliding door mounted on at least one side of a vehicle for sliding movement forwardly and rearwardly of the vehicle. The system includes a reversible motor. A bracket is guided within a guide along a fixed path between the opened and closed positions of the door. An elongated drive member is slidably disposed within the guide and connected to the bracket at one end for driving the bracket along the fixed path. A translator mechanism operably engages with the drive member for powering movement of the door. The translator mechanism can include a rotatable hub, operably engageable with the drive member, a gear transmission for driving the hub, and a clutch mechanism for connecting the motor to the transmission. The translator mechanism preferably has sufficient power to pull the sliding door into a primary latch position with respect to the corresponding portions of a latch mechanism attached to the door and frame defining the door opening. A power striker moves the door into and out of sealing engagement with the frame. A lock mechanism selectively maintains the latch in a locked position. At least one sensor provides an input signal to a control system corresponding to movement of the door, position of the lock mechanism, and position of the power striker for controlling the door drive unit, power striker drive unit, and lock mechanism drive unit in accordance with a program stored in memory.
Abstract:
A power operating system for opening and closing a vehicle liftgate has a pair of drive units supported on the vehicle roof and connected to the liftgate for opening and closing the liftgate. Each drive unit includes a housing having a curved track and a curved gear rack that is bodily movable endwise in the housing and guided by the curved track, the rack also serving as the drive link between the housing and the liftgate. The combined rack and drive link is extended and retracted by a pinion gear that is journalled interiorly in the housing and engages the teeth of the curved gear rack. The pinion gear is rotated by the output shaft of the motor, which in turn is fastened to the side of the housing. The motor is a reversible electric motor and is adapted to be operably coupled to the vehicle ECU unit and preferably includes an internal transmission and electrically operated clutch controlled by the ECU unit.
Abstract:
An operating device for operating an automotive pivotal door has the following elements, which are an electric motor of reversible type; a speed reduction device driven by the motor and having an output part formed into an output gear; a rack member having a toothed side edge meshed with the output gear, so that upon energization of the motor, the rack member is moved axially; a motion transmitting member having one end pivotally connected to one end of the rack member and the other end connected to the pivotal door; and a structure which permits a swing movement of the rack member about an axis of the output gear when an external force is applied to the rack member in a direction to swing the same during the axial movement of the rack member. For appropriately controlling the operating device, a computer-aided control unit is employed.
Abstract:
A rotary damper uses a motor to selectively dynamically brake the rotational movement between a housing and a cover of a wireless communications device. A clutch that is moveable between an engaged position and a disengaged position connects the motor to the cover so that the relative rotational movement between the housing and the cover in at least one rotational direction is resisted by the motor when the clutch is in an engaged position. The clutch preferably includes a coupler axially moveable between a deployed position directly engaging the flip cover and a retracted position disengaged from the cover, and an actuator moveable between a first position and a second position so as to cause the coupler to assume the deployed position and the retracted position, respectively. The actuator preferably includes a spring to bias the coupler towards the deployed position. A shaft preferably extends through the motor and connects the actuator to the coupler. The coupler may rotate at a slower speed relative to the shaft or may rotate at the same speed. The rotary damper may also include an eccentric weight attached to the shaft so as to spin therewith. When the clutch is in the disengaged position, the motor may intermittently spin the shaft causing the eccentric weight to spin, thereby imparting a shaking motion to the overall phone.

Abstract:
A power sliding door assembly for a motor vehicle comprising a door structure constructed and arranged to be mounted on a motor vehicle for movement between closed and opened positions and a drive assembly mounted on the door structure. The drive assembly includes a rotatable gear engageable with a gear track provided on the vehicle. The rotatable gear is drivable in a one direction to effect movement of the door towards the opened position and drivable in an opposite direction to effect movement of the door structure towards the closed position. A drive shaft is coupled with the drive assembly and is constructed and arranged to rotatably drive the rotatable gear. A reversible motor is mounted on said door structure and is energizable to drive the drive shaft in a first direction to enable the drive shaft to drive the rotatable gear in the one direction, and energizable to drive the drive shaft in a second direction opposite the first direction to enable the drive shaft to drive the rotatable gear in the opposite direction. A clutch assembly is provided that is constructed and arranged to selectively couple the reversible motor with the drive shaft, so that the reversible motor is coupled to the drive shaft when energized to rotate the drive shaft in either of the first and second directions, and so that the reversible motor is de-coupled from the drive shaft to prevent back-driving of the motor when the door structure is manually moved between the opened and closed positions.
Abstract:
Apparatus for opening and closing a deck lid of a vehicle body. An elongated rack is mounted in a housing for longitudinal movement. A rotatable pinion meshes with the rack to move the rack longitudinally in one direction or the other depending on the direction of rotation of the pinion. A reversible motor rotates the pinion in opposite directions. The deck lid is attached to a pair of arms pivoted to the vehicle body. A link has one end pivoted to the rack and the opposite end pivoted to one of the arms. The deck lid is moved to open position in response to longitudinal movement of the rack in one direction or to closed position in response to longitudinal movement of the rack in the other direction.
Abstract:
One end of a connection wire is connected to a rear vehicle door which can be popped up by an urging force from a user. An apparatus for maintaining the position of the upwardly swinging rear door once it is opened at a desired angle includes a pulley for receiving the other end of the connection wire wound around it. A power spring urges the pulley in a connection wire-winding direction. A one-way clutch includes a rotatable outer ring with an input shaft at the center thereof. The input shaft is connected to the pulley. The input shaft is also connected to the outer ring through multiple rollers interposed between the outer ring and the input shaft so that the pulley is allowed to rotate in the connection wire-winding direction. In maintaining the upwardly swinging rear door at a desired angle once it is opened, a solenoid is energized to move a stopper into an engaging groove on the periphery of the outer ring. When the stopper engages the engaging groove, the rotation of the outer ring is restricted. In opening or closing the rear door, the solenoid is de-energized to disengage the stopper from the engaging groove. Consequently, the outer ring is allowed to rotate freely.
