Definitions

  • the invention relates to liftgate assemblies for motor vehicles. More specifically, the invention relates to a power drive assembly for a liftgate assembly for providing power to move the liftgate assembly between open and closed positions.
  • a power drive assembly for a motor vehicle is disclosed.
  • the motor vehicle defines an opening and a liftgate that is pivotal between a closed position covering the opening and an open position providing access through the opening.
  • the power drive assembly includes a base that is fixedly secured to the motor vehicle at a position in spaced relation to the opening.
  • a drive mechanism is fixedly secured to the guide.
  • the drive mechanism converts electrical energy into a linear force.
  • the power drive assembly includes a translation linkage connected to the drive mechanism for receiving the linear force and translating it into a nonlinear force to move the liftgate between the open position and the closed position.
  • the liftgate 12 is pivotally mounted to the motor vehicle 10 with a hinge 14.
  • the hinge 14 allows the liftgate 12 to move between its two extreme positions shown in Figures 1 and 2.
  • access is provided to the motor vehicle 10 through an opening 16.
  • a piece of trim 18 extends along the sides
  • the base 24 includes two side flanges 30, 32. Both of the side flanges 30, 32 extend along the longitudinal sides of the base 24 generally perpendicular to a support section 34 of the base 24. The two side flanges 30, 32 and the support section 34 form a generally U-shaped cross section.
  • the second side flange 32 includes a slot 36 extending therealong. The slot 36 is linear and will be discussed in greater detail subsequently.
  • the clutch 46 allows an operator of the liftgate 12 to override the power drive assembly 22 and open or close the liftgate 12 manually. Therefore, the clutch 46 allows the operator to open or close the liftgate 12 at a speed other than that which is set by the power drive assembly 22. It should be appreciated by those skilled in the art that, without adding to the inventive concept shown herein, the clutch 46 may be removed in systems that do not permit manual operation.
  • a transmission 48 receives the output force from the clutch 46 and redirects it.
  • the transmission 48 includes a plurality of gears that are rotatably mounted to the base 24. The transmission 48 also is used to further increase torque output of the drive mechanism 38.
  • Bracketally secured to the bracket end 66 of the translation linkage 58 is a bracket 68.
  • the bracket 68 extends through an arc that terminates with a pivotal connection with the liftgate 12. More specifically, the bracket 68 extends between the translation linkage 58 and the liftgate 12.
  • the arcuate path of the bracket 68 allows an opening 70 in the top trim piece 20 to be smaller. More specifically, the arcuate shape of the bracket 68 defines a constant cross-sectional area as the bracket 68 travels through the opening 70.
