Definitions

  • the subject invention relates to a power striker mechanism for use with a closure panel of a motor vehicle.
  • a vehicle closure panel such as a door, hood or deck, typically includes a seal to prevent exterior environmental elements from intruding into a passenger compartment.
  • the seal also reduces the amount of exterior noise transmitted into the passenger compartment. Seals with higher stiffness coefficients and greater seal pressures are being used to accommodate consumer demand for a quieter passenger compartment. In other words, new seals are becoming much stiffer than those traditionally used. As appreciated, a stiffer seal translates into an increase in force required to completely close the closure panel.
  • a power striker including the power strikers disclosed in United States patent nos. 5,172,947; 4,739,585; 4,982,984; 5,716,085; 5,755,468; 4,842,313; 4,775,178; 4,707,007; 5,765,886; and 5,066,056.
  • the closure panel is moved to an initial closed position such that the latch engages the striker.
  • the striker is then moved inboard by a power actuator to cinch the closure panel to a final closed position compressing the seals.
  • US-A-4 869 537 discloses a power striker mechanism as defined in the preamble of claim 1.
  • the disadvantages of the prior art may be overcome by providing a power striker that isolates the actuator from slamming loads imparted to the striker assembly.
  • a power striker mechanism having a housing.
  • a striker is mounted on a striker plate that is mounted on the housing for slidable movement between an inboard and an outboard position.
  • a driver plate is mounted to the housing for slidable movement is a direction orthogonal to the striker plate.
  • An actuator effects movement of the driver plate to thereby effect movement of the striker plate between the inboard and outboard positions.
  • the striker plate has a pin and the driver plate has an S-shaped slot defining a camming relation. The pin slidably engages the S-shaped slot.
  • the S-shaped slot has end regions extending in the orthogonal direction and is interconnected by a diagonally extending section.
  • a power striker mechanism there is provided a power striker mechanism.
  • the striker plate and the driver plate are connected together in a camming relation having end phases corresponding to inboard and outboard positions of the striker plate.
  • the striker plate and the driver plate are coupled to the housing of the mechanism.
  • the striker plate and the driver plate are uncoupled from the housing enabling the relative sliding movement of the striker plate and the drive plate.
  • a power closure panel striker mechanism is generally shown at 10 in Figures 1 and 2.
  • the power striker mechanism 10 comprises a striker assembly 12. a driver assembly 14 and an actuator 16.
  • the striker assembly 12 includes a striker plate 20.
  • the striker plate 20 has three aligned holes, with a center hole sized for mounting a driver pin 36.
  • the striker plate 20 is slidingly disposed within a cavity 24 of a striker housing cover 22.
  • the striker correspondingly 18 extends through a rectangular opening 25 in the striker housing cover 22.
  • the striker housing cover 22 fits within a peripheral rim 26 of a backplate 28.
  • the striker housing cover 22 has two countersunk mounting holes 30 through which two mounting screws (not shown) are inserted to secure the striker assembly 12 to the vehicle.
  • the backplate 28 secures the striker housing cover 22 at a top and bottom portion by a lip 32 folded over the striker housing cover 22.
  • the pin driver 36 extends through a slot 38 in the backplate 28. Further, the backplate 28 cooperates with the striker housing plate 22 to define a first cavity therebetween.
  • striker housing cover 22 has a transverse embossment which receives and secures striker bushings 34 above and below the striker plate 20 within the striker housing cover 22 defining a first channel.
  • the striker bushings 34 are held firmly between the striker housing cover 22 and the backplate 28.
  • the striker bushings 34 allow an inboard and outboard sliding movement of the striker plate 20 in the direction of arrows A, B.
  • the driver pin 36 and striker 18 are also limited to horizontal movement along with the striker plate 20.
  • the driver pin 36 fits within a roller 40 disposed within the driver assembly 14, which is also shown in Figure 4.
  • the roller 40 follows within a cam slot 42 of a driver plate 44 in a camming relation.
  • the driver plate 44 is rectangular having the cam slot 42 and a set or series of gear teeth 46.
  • the cam slot 42 has an S-shaped profile defined by three phases.
  • the end phases comprise outboard 41 and inboard 43 ends and an intermediate phase comprising a diagonal connection therebetween.
  • Outboard end 41 and inboard end 43 extend parallel to each other and generally orthogonal to the inboard outboard movement of the striker plate 20.
  • a driver housing plate 48 has rectangular aperture 49 which enables the operative engagement between the actuator 16 and the drive plate 42.
  • driver housing plate 48 has a rectangular embossment.
  • the cover 50 includes upper and lower tabs 54 that are folded over the driver housing plate 48 to secure the driver assembly 14 and define a second cavity therebetween.
  • the cover 50 has an aperture 51 through which the pin 36 extends.
  • a pair of driver bushings 56 are mounted within the second cavity to define a second channel.
  • the driver plate 44 slides within the second channel defined by the driver bushings 56 in a direction perpendicular to the inboard outboard movement of the striker plate 20.
  • the gear teeth 46 of the driver plate 44 engage a sector gear 58.
  • the sector gear 58 is mounted to the support bracket 66 and has a first set of gear teeth 60 that engages the driver plate 44 and a second set of gear teeth 62 that engages a pinion 64 of the actuator 16.
  • the actuator 16 is mounted to an internal support within the vehicle.
  • a support bracket 66 is a rectangular plate having an opening for the drive gear 64 and is secured to the actuator 16 to provide a mounting location for the sector gear 58.
  • the sector gear 58 is pivotally attached to the support bracket 66.
  • the sector gear 58 transmits rotary motion of the drive gear 64 to the driver plate 44 and acts as a lever arm to multiply torque provided by the motor 16.
  • the position of the striker 18 may be adjusted laterally while maintaining engagement of the driver plate 44 to the sector gear 58 due to extra width provided in the driver gear teeth 46.
  • the subject power striker mechanism 10 is configured to prevent transmission of impact forces on the striker 18, by a slammed closure panel, back through the driver assembly 14 and to the gear motor 16. An impact force imparted on the striker 18 will be in an inboard outboard direction.
  • the operation of the power striker mechanism 10 begins once the vehicle closure panel is moved to an initial closed position and the latch on the vehicle closure panel, typically a door, hood or deck, has latched onto the striker 18.
  • the actuator 16 is energized to rotate the drive gear 64 that in turn rotates the sector gear 58.
  • the rotation of the sector gear 58 forces the driver plate 44 to slide.
  • the driver plate 44 engages the roller 40, responsively moves the roller 40 along the outboard end 41 and then diagonally towards the inboard end 43 and then along the inboard end 43.
  • the drive pin 36 which engages the roller, responsively transmits the inboard movement to the striker plate 20 and striker 18, causing the striker 18 to move inboard (Arrow A) and pull the vehicle closure panel to a final closed position.
  • the driver plate 44 and the striker plate are uncoupled from the housing enabling the sliding movement of both and thereby effect the inboard and outboard movement of the striker plate 20. Therefor, forces applied to the striker 18 will not be converted to movement of the driver plate 44.
  • the S-shaped profile of the cam slot 42 prevents impact forces from being transmitted to the actuator 16. Impact loads are ultimately transmitted to the vehicle. The result is the atctuatorl6 being insulated from impact forces exerted on the striker 18.
