Abstract:
A drive mechanism is provided for a door operator, comprising a drive member and a driven member. The drive member includes a protrusion, the edges of the protrusion forming first and second driving surfaces which define a free space of at least about 90° there between. The driven member includes a protrusion, the sides of the protrusion form a first and a second driven surface, respectively. The drive member is adapted to be operably connected to between a motor assembly for rotating the drive member and a door closer assembly rotating with the driven member. The drive member and the driven member are disposed for relative rotation in substantially the same plane such that the driven member protrusion moves in the free space defined by the driving surfaces of the drive member protrusion. Rotation of the drive member from a first angular orientation to a second angular orientation in a direction toward an adjacent driven surface causes rotation of the driven member for powered opening of the door from the closed position to the open position. The driven member protrusion moves in the free space without engaging the protrusion surfaces when the door is opened manually from the closed position and allowed to close.
Abstract:
A door operating apparatus includes a motor bracket that covers a driving shaft of a driving motor; an output shaft that is disposed from the motor bracket toward the supporting bracket so as to be orthogonal to an extending direction of the driving shaft; a first rotational element that is linked with the driving shaft, and disposed on the output shaft; a second rotational element that is linked with a door operating mechanism, and disposed between the first rotational element and the supporting bracket on the output shaft; and a clutch unit including a clutch driving section that supports a rotation of the output shaft. When the first rotational element and the second rotational element are engaged by driving of the clutch driving section, the door operating mechanism is actuated by the driving force.
Abstract:
A drive train for a pivotable flap of a motor vehicle includes a holding device which can hold the flap in at least one open position, a first element which can be driven by a drive motor, and a second element connected to the pivotable flap to pivot the flap in response to movement of the first element. When the second element is moved along a path of motion relative to the first element counter to a specific spring force, a sensor generates a signal indicating relative motion of the elements, and a control device releases the holding device in response to the signal, whereby the flap can be moved manually by applying a force counter to the spring force.
Abstract:
An opening and closing apparatus for an opening and closing body of a vehicle. The opening and closing apparatus includes a reciprocating member connected at its connecting portion to a motor so as to be moved to reciprocate along a plane perpendicular to a hinge shaft, the reciprocating member having a side surface parallel with the plane perpendicular to the hinge shaft. A connecting member is provided having a first end section pivotally attached to an end portion of the reciprocating member, and a second end section fixed to the opening and closing body. A deflection-suppressing device is provided to a stationary body connected to the vehicle body. A part of the side surface of the reciprocating member is slidably contacted with the deflection-suppressing device and is located between the connecting portion of the reciprocating member and the connecting member.
Abstract:
The door-opening/closing apparatus includes a door, a driving unit that drives the door to close the door, a door movement detection unit that detects a movement of the door, an electrostatic switch that is mounted on the door for detecting a human's touching the door, and a judgment unit that judges whether the door is attempted to be closed. When the door movement detection unit detects a movement of the door, and when the electrostatic switch senses a human's touching the door, the judgment unit judges that the door is attempted to be closed, and then the driving unit drives to close the door.
Abstract:
A drive mechanism assembly for enabling driving and manual movement of a sliding side door. The assembly has a track assembly mounted to a vehicle body at a predetermined height and a drive mechanism mounted to the sliding side door so as to be proximate to a door latching mechanism. The drive mechanism has an input drive motor driving an output gear assembly engaging the track assembly and a transmission gear assembly with a sliding gear which selectively couples the input drive motor and an input gear assembly to the output gear assembly between an engaged position for driving movement or disengaged position for manual movement of the sliding side door. In this way, the slide side door may be moved manually between open and closed positions without having to overcome the effort required of rotating the drive motor.
Abstract:
An activating mechanism is provided for use with a four-link hinge of the type typically used for closure of a vehicle movable deck, such as a trunk lid or engine compartment hood. A lower link bracket is secured to the vehicle body and an upper link bracket is secured to the movable deck. Pivoting links may be connected between the upper and lower link brackets.
Abstract:
A drive assembly for a vehicle door, comprising: a motor having a driving member; a housing having a shaft rotatably received therein; an input member being rotatably received upon the shaft, the input member being operatively associated with the driving member, wherein rotation of the driving member causes rotation of the input member; an armature mounted on the input member; a rotor fixedly secured to the shaft, the rotor being cylindrical in shape and has a plurality of teeth positioned along the periphery of the rotor, the teeth being positioned in an equidistant manner; a coil mounted to the housing, the coil providing magnetic flux lines through the rotor to attract the armature when the coil is energized; and an inductance sensor assembly mounted to the housing in a facing spaced relationship with respect to the plurality of teeth of the rotor, wherein rotational speed and direction of the rotor is detected by the inductance sensor assembly.
Abstract:
Provided is a power actuator system for actuating a closure member (1) such as a trunk lid which is compact in size and has a minimized protrusion. A first link (8) is connected to an output shaft of a powered actuator (7), and a free end of the first link is connected to an end of a second link (9). The other end of the second link is pivotally connected to a hinge arm (4) which is fixedly attached to a closure member and pivotally supports the closure member to a fixed part such as a vehicle body. The first link is adapted to extend substantially from the output shaft towards the closure member as the first link swing around the output shaft, and the second link extends substantially perpendicularly with respect to the center line.
Abstract:
A power-operated system for actuating the liftgates of motor vehicles is disclosed. The system includes a controllable strut with internal locking structure that includes a driver and a valve assembly. The controllable strut is typically mounted on one side of the liftgate between the liftgate and the vehicle's frame. Conventional strut may be mounted on the other side of the liftgate. One end of each strut is connected to a powered articulating arm. To move the liftgate between open and closed positions, the articulating arms move the controllable strut and the other strut between positions of greater and lesser mechanical advantage. During the movements, the locking structure in the controllable strut may be activated and deactivated either cyclically or continuously to momentarily to retain the controllable strut as particular lengths.
