JPS5819967Y2 - Rear wiper mounting structure for glass back door cars - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a rear wiper mounting structure for a vehicle with a glass back door.

Conventionally, this type of wiper installation structure has been either to attach the motor directly to the inside of the glass and place the wiper on the outside, or to install it next to the rear seat using the door hinge metal fittings at the top and the glass surface. It was equipped with wipers.

However, this arrangement reduces rear visibility and
This resulted in a narrow living space, and also had drawbacks such as motor noise, deterioration of the appearance, and the risk of injury to occupants in the event of an accident.

Therefore, the present invention aims to solve the above-mentioned problems and provide a wiper system.

The present invention will be described below with reference to the drawings.

In order to exclude the wiper motor from the rear view, the system of the present invention includes a wiper pivot part that protrudes from the rear end of the car body leaf, which is isolated from noise, a wiper blade that is operatively attached to the pivot part, and a wiper blade that is operatively attached to the pivot part. A wiper drive mechanism disposed within the space formed by the quarter inner panel and the quarter outer panel of the roof side panel is driven and coupled by a flexible cable disposed through the space formed by the roof side inner panel and the outer roof side panel. This is a glass back door wiper device.

The wiper device □ shown in Figs. 1 and 3 shows an example of a conventional model.
As shown in the figure, the motor 1 is mounted directly inside the glass ρ with the wiper pivot protruding outward from the back door glass 2, where 3 is a wiper arm.

In the second structure, as shown in FIG. 4, the motor is supported and fixed to the door glass 2 using the back door hinge part 4.

FIG. 5 is a partially cutaway perspective view showing the outline of the device of the present invention. As is clear from the figure, the motor 1 is located at the rear lower part of the vehicle body.
The wiper pivot portion 5 is disposed within a space formed by a quarter inner panel and a quarter outer panel that serve as outer shell members, while the wiper pivot portion 5 is located between the rear end of the roof panel 6 and the ceiling material 7, as shown in the cross section of FIG. A wiper blade is attached to the tip of the roof panel 6 which protrudes through the space formed between the roof panel 6 and the roof panel 6.

Further, as shown in FIG. 7, a pinion 8 is fixedly installed at the lower end of the pivot, and a rack member 9 attached to the tip of a flexible cable from a drive device is meshed and driven with the pinion 8. .

The above-mentioned pivot portion 5 and the driving device (motor) 1 that is its driving source are connected to the roof side outer panel 10 and the roof side inner panel, as shown in the partial cross-sectional views of FIGS. Pass through the space formed by the panel 11 (Fig. 8), the space between the back door opening frame 12 and the ceiling material 7 (Fig. 6), which has a concave portion protruding outward from the rear of the vehicle body, etc. The wiper drive and interlocking device 1 is driven and connected by a flexible cable 13 that passes through a part of the roof side outer panel 10 and is disposed along the side of the vehicle body without being exposed to the inside or outside of the vehicle body. An example is shown in FIG. 9, in which a gear 14 that is rotationally driven by a motor 1 has a crank arm 15 pivoted on its circumferential side, and a crank arm 15 at its tip that reciprocates within the casing. A piston member 16 is pivotally connected to the other end of which a flexible cable 13 inserted into a cable tube 18 is fixedly extended.

On the other hand, a rack member 9 attached to the end of the cable meshes with the pinion 8 of the wiper pivot mechanism attached to the rear end of the roof, and the rack W is configured to reciprocate within a predetermined guide portion. From there, it makes a reciprocating motion accompanying the reciprocating motion of the cable.

Accordingly, the pinion 8 is rotated repeatedly in two directions, and this movement functions as a wiper blade.

Since the present invention is configured as described above, the flexible cable is routed through the through hole a of the roof side outer panel C member having a closed cross section, and is guided upward while being stored inside the closed collapsible structure. It will be destroyed.

In this state, the cable 13 and motor 1 are both inside the vehicle body.
Since it is arranged between the outer structural members, the inner trim surface d (the eighth
Figure) is not affected.

The cable 13 that comes out from the penetration part 6a (Fig. 5) on the side part of the roof to the indoor side is connected to the back door opening frame 1.
2 (Fig. 6), passing through the concave part protruding outward from the vehicle body,
The pinion 8 of the pivot portion 5 is assembled with the pinion 8 and stored in the recess of the back door opening frame (FIG. 7).

With the above-mentioned structure, the drive unit is housed away from the passenger seat, and the motor, cable, wiper pivot, etc. are all placed outside from the panel-membrane surface without being bothered by motor noise. It is stored and does not protrude into the ceiling material or trim surface, ensuring sufficient passenger space and the rear wall of the back door, and since a heavy motor is attached to the back door, it is easy to open and close the door. .
