Definitions
- the subject invention relates to a power st ⁇ ker 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 pre ⁇ ent exterior environmental elements from intruding into a passengei compartment
- the seal also reduces the amount of exterior noise transmitted into the passenger compartment Seals w ith higher stiffness coefficients and greater seal pressures aie 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 m 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 closuie panel to a final closed position compressing the seals
- a power st ⁇ ker mechanism having a housing A st ⁇ ker is mounted on a st ⁇ ker plate that is mounted on the housing for s dable movement between an inboard and an outboard position A driver plate is mounted to the housing for shdable movement is a direction orthogonal to the striker plate An actuator effects movement of the d ⁇ ver plate to thereby effect movement of the striker plate between the inboard and outboard positions
- the st ⁇ ker plate has a pm and the diner plate has an S-shaped slot defining a camming relation The pm shdably engages the S-shaped slot
- the S- shaped slot has end regions extending m the orthogonal direction and is interconnected by a diagonally extending section When the pin is m the end regions of the S-shaped slot, forces imparted
- Figure 1 is an exploded view of a powered striker mechanism of the present invention
- Figure 2 is a perspecti e view of the assembled powered striker mechanism of Figure 1
- Figure 3 is a perspective view, partially in section, of the striker assembly of Figure 1
- Figure 4 is a perspective view , partially m section, of a d ⁇ ver assembly for the powered st ⁇ ker mechanism of Figure 1
- a power closure panel striker mechanism is generally shown at 10 in Figures 1 and 2
- the power striker mechanism 10 comprises a st ⁇ kei assembly 12, a driver assemblv 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 drn er pin 36
- the st ⁇ ker plate 20 is slidingly disposed within a cavity 24 of a striker housing cover 22
- the st ⁇ ker correspondingly 18 extends through a rectangular opening 25 in the striker housing cover 22
- the st ⁇ ker housing cover 22 fits within a pe ⁇ pheral ⁇ m 26 of a backplate 28
- the striker housing cover 22 has tw o counteisunk 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 st ⁇ ker housing cover 22
- the pm dm er 36 extends through a slot 38 m the backplate 28 Further, the backplate 28 cooperates w ith the striker housing plate 22 to define a first cavity therebetw een
- striker housing cover 22 has a transverse embossment which receives and secures st ⁇ ker bushings 34 above and below the striker plate 20 within the striker housing co er 22 defining a first channel
- the striker bushings 34 are held firmly between the st ⁇ ker housing cover 22 and the backplate 28
- the st ⁇ ker bushings 34 allow an inboard and outboard sliding movement of the striker plate 20 in the direction of arrows A, B As appreciated
- the d ⁇ ver pm 36 fits within a roller 40 disposed within the d ⁇ ver assembly 14, which is also shown in Figure 4
- the roller 40 follows within a cam slot 42 of a d ⁇ ver plate 44 in a camming relation
- the d ⁇ ver plate 44 is rectangular having the cam slot 42 and a set or se ⁇ es of gear teeth 46
- the cam slot 42 has an S-shaped profile defined by three phases
- 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
- 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 d ⁇ ver housing plate 48 to secure the d ⁇ ver 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 d ⁇ ver plate 44 slides within the second channel defined by the d ⁇ ver 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 d ⁇ ve 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 d ⁇ ve gear 64 to the d ⁇ ver 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 st ⁇ ker 18, by a slammed closure panel, back through the driver assembly 14 and to the gear motor 16 An impact force imparted on the st ⁇ ker 18 will be in an inboard outboard direction
- the operation of the power st ⁇ ker 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 drn e 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 mo ⁇ es the roller 40 along the outboard end 41 and then diagonally towards the inboard end 43 and then along the inboard end
