Definitions

  • the invention relates to an assembly for opening and closing a liftgate of a motor vehicle. More specifically, the invention relates to an automated assembly designed to move a liftgate of a motor vehicle between an open position and a closed position.
  • Motor vehicles commonly include a liftgate typically connected to the rear of the vehicle. These liftgates are pivotal between an open position and a closed position to selectively provide access to the rear compartment of the vehicle. These liftgates are typically manually operated by pivoting the liftgate about a pair of hinges between the open and closed positions. A pair of hydraulic or pneumatic cylinders are often connected between the liftgate and the vehicle to assist in the opening of the liftgate and in maintaining the liftgate in the open position.
  • US-A-3 716 945 discloses a power liftgate drive assembly allowing the manual opening or closing of the vehicle liftgate.
  • a slot in the driving gear accomodates lost motion between the driving gear and the driven arm.
  • the driving gear returns, after every powered actuation, to a middle position such that the pin will be able to slide in the slot in case of manual actuation or will be driven by an end portion of the slot in case of power mode.
  • US-A-3 716 945 describes all the features of the preamble of claim 1.
  • a power liftgate drive assembly moves a liftgate of a motor vehicle between an open position and a closed position.
  • the power liftgate assembly includes a bracket that is mounted to the motor vehicle adjacent the liftgate.
  • the drive mechanism is fixedly secured to the bracket.
  • the drive mechanism provides a bidirectional rotational force.
  • a gear is pivotally secured to the bracket.
  • the gear is coupled to the drive mechanism to receive the bidirectional rotational force to pivot the gear with respect to the bracket.
  • the gear defines a slot extending between first and second ends.
  • the power liftgate drive assembly also includes a striker bar coupled to the gear. The striker bar slides through the slot.
  • a guide rod connects the striker bar to the liftgate.
  • the power liftgate drive assembly also includes a latch secured to the gear and operable between a latched position and an unlatched position.
  • the latch engages the striker bar when in the latched position. This prevents the striker bar from moving along the slot.
  • the striker bar moves through movement of the gear which is moved to power the liftgate between the open and closed positions.
  • the latch disengages the striker bar when in the unlatched position allowing the striker bar to move along the slot allowing the liftgate to be moved manually between the open and closed positions.
  • the motor vehicle 10 includes a rear portion defining a rear access opening 12.
  • the rear access opening 12 provides access into the compartment immediately adjacent thereto.
  • a liftgate, or tailgate, 14 is pivotally secured to the rear portion of the motor vehicle 10 by a pair of gooseneck-shaped hinges 16.
  • the liftgate 14 pivots about the hinges 16 between an open position, shown in Figure 1, and a closed position covering the rear access opening 12 in a conventional manner.
  • a bracket 18 is mounted to a portion of the ceiling 19 of the motor vehicle 10 adjacent the rear access opening 12.
  • a headliner 20 covers the bracket 18 and the rest of the assembly 22, discussed in greater detail subsequently.
  • a portion of the headliner 20 is shown cut away to view the assembly 22. While the assembly 22 is shown secured to the ceiling 19 under the headliner 20, it should be appreciated by those skilled in the art that the assembly 22 may be mounted to a pillar or another structural element of the motor vehicle 10 other than the ceiling 19 thereof.
  • the assembly 22 is a sector gear power liftgate assembly.
  • the sector gear power liftgate assembly 22 includes a gear, generally shown at 24. While any gear may be used, including a linear rack, the gear shown in the embodiments is a sector gear 24.
  • a pivot axle 26 is used to mount the sector gear 24 to the mounting bracket 18 to allow the sector gear 24 to pivot thereabout. As is shown in the Figures, the sector gear 24 is positioned in a plane generally parallel to the mounting bracket 18.
  • the sector gear 24 includes a rack of gear teeth 28 on an arcuate edge thereof opposite the pivot axle 26.
  • the sector gear 24 defines a slot 30.
  • the slot 30 extends along a line in the embodiment shown in Figures 1 through 5.
  • the slot 30 is arcuate in the embodiment shown in Figure 6. This embodiment will be discussed in greater detail subsequently.
  • the slot 30 extends between a first end 32 and a second end 34 in a chord-like manner.
  • the slot 30 is between the pivot axle 26 and the rack of gear teeth 28.
  • a drive mechanism is fixedly secured to the bracket 18.
  • the drive mechanism 36 provides a bidirectional rotational force to drive the sector gear 24 between its two extreme positions.
  • the drive mechanism 36 includes a motor 38 that is powered through the electrical power system of the motor vehicle (not shown).
  • the motor 38 drives an output shaft 39 to rotate in either a clockwise or counter clockwise direction, depending on whether the liftgate 14 is to be opened or closed.
  • the output shaft 39 drives a toothed drive gear 40.
  • the toothed drive gear 40 meshes with the rack of gear teeth 28 and drives the sector gear 24 between its two extreme positions.
  • the toothed drive gear 40 acts as a pinion as it moves the rack of gear teeth 28.
  • the sector gear power liftgate assembly 22 also includes a striker bar 42.
  • the striker bar 42 is slideably retained within the slot 30 between the first 32 and second 34 ends.
  • An elongated guide rod 44 is connected to the striker bar 42.
  • the guide rod 44 extends between a first end 44, connected to the striker bar 42, and a second end 48.
  • the second end 48 is connected to the hinge 16 and, hence, the liftgate 14. Therefore, the guide rod 44 moves the liftgate 14 when the striker bar 42 is moved by the desires of the operator of the liftgate 14.
  • the hinge 16 includes a distal end 50 connected to the liftgate 14 and a proximal end 52.
  • the hinge 16 has a first pivot 54 pivotally connected to the mounting bracket 18 adjacent the rear access opening 12.
  • the hinge 16 also includes a second pivot 56 disposed adjacent to and offset from the first pivot 54. Both the first 54 and second 56 pivots are disposed adjacent the proximal end 52.
  • An arcuate hinge plate 58 interconnects the second end 48 of the guide rod 44 and the second pivot 56 of the hinge 16.
  • the hinge plate 58 provides the relationship between the hinge 16 and the guide rod 44 so that the hinge 16 pivots about the first pivot 54.
  • the hinge plate 58 and second end 48 of the guide rod 44 are connected by a shaft 60.
  • the power liftgate assembly 22 further includes a latch mechanism, generally shown at 62.
  • the latch 62 is secured to the sector gear 24.
  • the latch 62 operates between a latched position and an unlatched position.
  • the latch 62 engages the striker bar 42 to prevent it from moving relative to the sector gear 24.
  • the latch 62 engages the striker bar 24 to prevent the striker bar 42 from moving along the slot 30.
  • the movement of the sector gear 24 will translate into movement of the striker bar 42. This will result in the movement of the guide rod 44, hinge 16 and the liftgate 14.
  • the striker bar 42 is free to move through the slot 30 in the sector gear 24 providing the freedom to manually open and close the liftgate 14.
  • the latch 62 includes a latch bracket 64 that is fixedly secured to the sector gear 24.
  • the latch 62 also includes a generally U-shaped latch plate 66 that is pivotally connected to the latch bracket 64.
  • the striker bar 42 is received within the latch plate 66 when the latch plate is in the latched position.
  • a latch pawl 68 is pivotally coupled to the bracket 64 for engaging and pivoting the latch plate 66 between the latched position and the unlatched position.
  • a coil spring 70 is connected to the latch pawl 68 to bias the latch plate 68 in the unlatched position.
  • An actuator 72 is also fixedly secured to the sector gear 24.
  • the actuator 72 is powered to move the latch plate 68 between the latched and unlatched positions.
  • the actuator is solenoid driven.
  • the power liftgate drive assembly 22' is configured to have an arcuate slot 30'.
  • the arcuate slot 30' extends through the same arc that the rack of gear teeth 28' extend.
  • the solenoid actuator 72' is removed from the sector gear 24'.
  • the cover, headliner or otherwise does not have to extend out as far because the solenoid actuator 72' and solenoid 74 do not travel through an arcuate path with the sector gear 24'. This reduces the amount of space consumed in the compartment by the power liftgate drive assembly 22'.
  • the powered liftgate drive assembly 22 enables both powered and manual opening and closing of the liftgate 14 of the motor vehicle 10 to provide selective access to the rear compartment of the motor vehicle 10.
  • the power liftgate drive assembly 22 allows the liftgate 14 to be manually pivoted between the open and closed positions.
  • the striker bar 42 is positioned along the slot 30 toward the first and 32 by the force of the guide rod 44 connected to the hinge 16.
  • the hinges 16 pivot about the first pivot 54 and, thus, rotate the second offset pivot 56.
  • the guide rod 44 which is connected between the hinge 16 of the striker bar 42 forces the striker bar 42 to slide along the slot 30 from the second end 34, as shown in Figure 5, to the first end 32, as shown in Figure 4.
  • the latch plate 66 remains in the unlatched position disengaged from the striker bar 42 and the sector gear 24 remain stationary about the pivot axle 26.
  • the reverse movement occurs when the liftgate is manually pivoted about its hinges 16 back to the closed position. More specifically, the guide rod 44 is pulled by the hinges 16 to slide the striker bar 42 along the slot 30 from the first end 32 to the second end 34.
  • the liftgate 14 may be automatically pivoted between the open and closed positions by the power liftgate drive assembly 22.
  • the operator activates a switch within the motor vehicle 10, a key fob, or controller (not shown) to actuate the latch mechanism 62 and drive mechanism 36.
  • the solenoid actuator 72 engages the latch pawl 68 to pivot the latch plate 66 from the unlatched position to the latched position to engage the striker bar 42.
  • the motor 38 is then powered, or energized, to drive the drive gear 40.
  • the drive gear 40 which is matched with the rack of gear teeth 28, drives or pivots the sector gear 24 about the pivot axle 26 in the counterclockwise direction.
  • the guide rod 44 pulls on the second offset pivot 56 to pivot the hinge 16 about the pivot 54 to close liftgate 14.
  • the motor 38 is reversed so that the drive gear 40 pivots the sector gear 24 in a clockwise direction about the pivot axle 26.
  • the guide rod 44 forces the hinge 16 to pivot about the first pivot 54 and open liftgate 14.
  • the actuator 72 of the latch mechanism 62 may be controlled such that the latch plate 66 is returned to the unlatched position, or parked position, when the liftgate 14 is in either the open or closed positions to enable manual operation of the liftgate 14.
  • the motor 38 includes a hall effect sensor which acts as a position sensor to identify the position of the sector gear 24 for alignment and engagement between the striker bar 42 and the latch plate 66.
  • the sector gear 24 may be pivoted about the axle 26 to position the latch mechanism 62 with the striker bar 42 for actuation of the latch plate 66 from the unlatched position to the latched position engaged with the striker bar 42 for power operation of the liftgate 14.
  • a capacitor is charged to the voltage of the vehicle battery (not shown) and is electrically isolated from a coil (not shown) of the solenoid actuator 72.
  • the voltage is applied to the coil in a specific polarity. This causes the solenoid piston to be drawn in towards the coil. Once the piston is completely retracted into the coil, a permanent magnet maintains the piston in position.
  • the capacitor is discharged through the solenoid in the reverse polarity to that used for engagement.
  • the capacitor need only charge the solenoid enough to counterbalance the magnetic field generated by the permanent magnet, since a mechanical spring is used to assist the disengage process.
  • the capacitor is electrically on such that, in the event of a mid-cycle power failure, the capacitor will discharge through the solenoid and disengage the solenoid. Once disengaged, the power liftgate assembly 22 is returned to the manual operation condition.
  • assembly 22 being mounted on the roof panel. However, it is now apparent to those skilled in the art that assembly 22 may also be mounted in the quarter panel of the vehicle 10.
