Abstract

PURPOSE:To prevent a pivot and the like from being damaged in case of collision by mounting a wiper pivot onto a cowl panel whereby forming a cut-out section in a recess form at a place corresponding to the mounting position of the wiper pivot in the lower end section of a front window. CONSTITUTION:A mounting hole 1c for a wiper pivot 11 is formed in a window mounting surface 1b located upward from the end surface 5b of a front window 5. On the other hand, a cut-out section 18 is formed at a place corresponding to the mounting hole 1c in the lower end section 5a of the front window 5 fixed onto the cowl panel 1. Owing to this constitution, the wiper pivot 11 can be located upward from the lower end section 5b of the front window 5 even if the lower section 5a is set sufficiently downward not to expose the bonded section. Accordingly, as the wiper pivot 11 is sufficiently separated from a cowl front 2, the destruction of the pivot 11 can be prevented even if the cowl front 2 is deformed afterward in case of collision.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a retractable wiper having a wiper pivot attached to a cowl panel of a vehicle.

This invention relates to a wiper mounting structure for a vehicle in which a wiper pivot mounting portion is provided in the upper part of a cowl panel so that the engine or the like does not directly hit the wiper pivot and damage the front window in the event of a vehicle collision.

(Prior art) Recently, as a wiper device for a vehicle, for example,
As shown in Publication No. 1654, there is a known retractable wiper that is stored in a concave storage space formed in the front part of the front windshield when the wiper is not in use, in order to reduce air resistance while driving and improve its appearance. ing.

That is, in conventional retractable wiper devices.

As shown in FIG. 3, the cowl panel front 2 and the dash panel 3 are combined to create a closed cross-section structure 4.
The lower end 5a of the front window 5 is bonded to the rear end of the cowl panel l via a dam 6 and an adhesive 7. The rear part of the engine hood 8 is in contact with the front end rising i'iIIla of the cowl panel l through a sealing member 9, and the engine hood 8,
The cowl panel l is located and attached below the lower end 5a of the front window 5 in a concave wiper storage i'illlO formed by the cowl panel l, and when the wiper 12 is not in use, the wiper 12 is However, if the adhesive part at the lower end of the front window 5 is exposed to the outside, it will look bad, so the lower end 5a of the front window tends to move downward in the wiper storage part 10. be. Therefore, the wiper pivot 11 located further below the lower end portion 5a approaches the cowl front 2. As a result, the cowl front 2 is deformed by the retreat of the engine 14 during a vehicle collision, and the deformed cowl front 2 collides with the wiper pivot 11, wiper drive crank arm 15, or rod 16, damaging them. , an impact force is applied to the front window 5 via the wiper pivot 11 and the cowl panel 1, causing problems such as damage to the front window 5.

(Object of the Invention) The present invention was made to solve the above-mentioned problems, and has a simple structure that prevents damage to the wiper pivot and the front window in the event of a collision. An object of the present invention is to provide a wiper mounting structure for a vehicle that retains the advantages of a type wiper.

(Structure of the Invention) In order to achieve the above object, the present invention attaches the lower end of the front window to a cowl panel extending in the width direction of the vehicle body, attaches the wiper pivot to the cowl panel, A concave notch is formed at the lower end of the window at a position corresponding to the wiper pivot attachment portion.

According to the wiper mounting structure, the lower end of the front window and the wiper pivot are attached to the cowl panel, so they are not exposed to the outside, and when the wiper is not in use, the wiper itself is retracted and is not exposed to the outside.

In addition, since the position of the wiper pivot can be set above the lower edge of the front window, even if the front cowl is deformed and receives a large impact load, such as when the front cowl moves backward during a vehicle collision, the wiper There is no contact with the pivot.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a perspective view of the front part of a vehicle body showing an embodiment of the present invention;
FIG. 2 shows a sectional view taken along the line H--H in FIG. 1, and in the figure, parts corresponding to those in the conventional example in FIG. 3 are designated by the same reference numerals and will be explained. First, as shown in FIG. 2, the cowl panel l is arranged below the upper surface of the front hood 8, and extends in the width direction of the vehicle body. Together with the dash panel 3, the dash panel upper 15, etc., a closed cross-sectional structure 4 is formed that extends in the vehicle width direction.

Further, the rear end of the engine hood 8 is in contact with the front end rising portion 1a of the cowl panel l via a seal member 9, and the rear end of the engine hood 8 and the cowl panel l are in contact with each other through a seal member 9.
A wiper storage portion 10 is formed by these.

A window mounting surface 1b is formed at the rear of the cowl panel 1, and a mounting hole IC for a wiper pivot 11 is bored at a predetermined position on this window mounting surface 1b, as shown in FIG. .

Here, the mounting hole IC of the wiper pivot 11 is formed in the window mounting surface 1b located above the end surface 5b of the front window 5. On the other hand, a concave 9J notch 18 is formed at the lower end 5a of the front window 5 fixed to the window mounting surface 1b of the cowl panel L at a position corresponding to the mounting hole 1c of the wiper drive (wiper drive) 11. , the lower end 5a of the front window 5 is attached to the window mounting surface 1b of the cowl panel l with double adhesive 7A.
, 7B, and the wiper pivot 11 (FIG. 2) is fixed to the lower edge 5b of the front window 5.
It is attached to the attachment hole IC in the concave notch 18 formed higher up.

- Since the distributed adhesives 7A and 7B are double-layered, even if the lower adhesive 7A has a discontinuous shape due to the presence of the concave notch 5a, the one adhesive 7B can have a continuous shape. ,
Uniform adhesive force can be obtained in different locations.

In the "-2 configuration, the wiper pivot 11 shown in FIG. 2 is located within the concave cutout 18 of the front window 5, so that the lower end 5a of the front window 5, that is, the adhesive part, is not exposed to the outside. Even if the lower end portion 5a is set sufficiently below, the wiper pivot 11 can be placed at a sufficiently high position above the lower edge 5b of the front window 5. Therefore, since the wiper pivot 11 is pre-separated from the cowl front 2, the engine 14 is separated from the cowl front 2 in advance.
By moving backward and hitting the cowl front 2, even if the cowl front 2 deforms significantly backward, there is no risk of it colliding with the wiper pivot ll. Therefore, damage to the wiper pivot 11 is prevented, and damage to the front window 5 due to impact force being applied to the front window 5 via the wiper storage portion 1-11 and the cowl panel 1 is also prevented. . Moreover, the lower end 5a of the front window 5, that is, the adhesive part, is set downward as in the conventional case, and the wiper pivot 11 is not located above the lower end i5a, so that the lower end 5a and the wiper storage area ) 11 is not likely to be exposed to the outside.

(Effects of the Invention) As described above, according to the present invention, since the concave notch is provided at the lower end of the front window and the wiper pivot is positioned in this concave notch, the position of the lower end of the front window is The position of the wiper pivot 11 can be set upward while the wiper pivot 11 is set sufficiently downward. therefore,
This prevents damage to the wiper pivot and front window due to impact loads during a vehicle collision.
