Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a wiper pivot support structure for an air box in an automobile.

[Prior art]

A conventional wiper pivot support structure for an air box in an automobile is, for example, as shown in FIG. 5 (see Japanese Utility Model Laid-Open No. 62-131977).

That is, in the drawings, 1 is a dash upper panel, 2 is a cowl top panel which is joined to the front end of the dash upper panel 1 to form an air box B with the dash upper panel 1, and 4 is an inner rear end portion of the air box B. The vertical cross-section box-shaped reinforcing member is set to the upper end portion 1a of the dash upper panel 1, the upper panel 4a, and the lower panel 4b.
It is formed by.

Reference numeral 5 is a wiper arm, 6 is a wiper pivot attached to a base portion of the wiper arm 5, and the wiper pivot 6 is attached by a bolt 8 to a pivot bracket 7 whose base end portion is fixed to the reinforcing member 4. . Reference numeral 9 is a windshield glass.

[Problems to be solved by the device]

However, in such a conventional support structure,
Since the pivot bracket 7 is cantilevered with respect to the input of the wiper pivot 6, it is necessary to increase the rigidity to increase the plate thickness, and it is difficult to position the pivot bracket 7, and there is a risk that mounting variations will increase. There was a problem that the management man-hours for the

The present invention has been made in view of such conventional problems, and provides a wiper pivot support structure for an air box in an automobile that improves the rigidity of the pivot bracket without increasing the plate thickness and facilitates positioning of the pivot bracket. The purpose is to do.

[Means for solving the problem]

In order to achieve such an object, the present invention has a structure in which an air box is formed by a dash upper panel and a cowl top panel, and a box-shaped reinforcing member having a vertical cross section is provided at the inner rear end of the air box. The attached pivot bracket is bent from the inclined plate-like main body portion, the rear mounting piece portion bent and extended from the rear end of the main body portion and joined and fixed to the reinforcing member, and the front end portion of the main body portion. An extended connecting portion, a front mounting piece bent from the front end of the connecting portion and extending along the cowl top, and an upper end of the cowl top panel provided at the upper end of the front mounting piece It is formed by a positioning flange joined to the flange, and an easily refracting portion is formed at a boundary between the main body portion and the rear mounting piece portion.

[Action]

The pivot bracket is preferably bridged between the cowl top panel and the reinforcing member, and has both ends with respect to the input of the wiper pivot, so that the rigidity can be improved. Further, when mounting the pivot bracket, the positioning can be easily performed by joining the positioning flange to the upper end flange of the cowl top panel.

Further, when the vehicle collides, the pivot bracket is refracted at the front refraction portion, and is also refracted at the rear easy refraction portion to be rotated and escaped, so that the air box is easily collapsed.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings by attaching the same reference numerals to the same parts as those of a conventional example.

1 and 2, 1 is a dash upper panel, 2 is a cowl top panel which is joined to the front end of the dash upper panel 1 to form an air box B with the dash upper panel 1, and 4 is an air box B. A vertical cross-section box-shaped reinforcing member set at the inner rear end portion, and the upper end portion 1a of the dash upper panel 1 and the upper panel 4a,
It is formed with the lower panel 4b.

Reference numeral 5 is a wiper arm, 6 is a wiper pivot attached to the base of the wiper arm 5, and the wiper pivot 6 is attached to a pivot bracket 7 by bolts 8.

The pivot bracket 7 is the wiper pivot 6
And an inclined flat plate-shaped main body portion 7a to which is attached, and a rear mounting piece portion 7b which is bent and extended from the rear end of the main body portion 7a at a substantially right angle and is joined and fixed to the plate surface of the lower panel 4b of the reinforcing member 4. And a horizontal connecting portion 7c which is continuous with the front end of the main body portion 7a and extends horizontally, and a front mounting portion which is bent substantially at a right angle from the front end of the horizontal connecting portion 7c and extends along the cowl top panel 2. It is formed by a piece portion 7d and a positioning flange 7e provided on the upper end of the front attachment piece portion 7d and joined to the upper end flange 2a of the cowl top panel 2.

Although the upper end flange 2a and the positioning flange 7e are fastened together using the attachment clip 12 of the seal member 11 that seals the inside and outside of the hood 10 and the engine room ER in the figure, they may be fixed by spot welding.

Main body 7a of the pivot bracket 7, rear mounting piece
Reinforcing flanges 7f, 7 are provided on both side edges of the horizontal connecting portion 7c and 7b.
f is formed, in the bending portion which is a boundary portion between the main body portion 7a and the rear mounting piece portion 7b in the reinforcing flanges 7f, 7f, a notch 13, which is an easily bending portion for promoting crushing during a vehicle collision, 1
3 is formed.

In addition, 9 is an unshielded glass, 14 is a cowl cover, a penetrating portion of the wiper pivot 6 is a fool hole 14a, and its front end is attached to the upper end flange 2a of the cowl top panel 2 together with the positioning flange 7e. 12
It is fastened together by.

With this configuration, the pivot bracket 7 is ideally bridged between the cowl top panel 2 and the reinforcing member 4 and is both-supported with respect to the input of the wiper pivot 6, so that the rigidity is improved without increasing the plate thickness. be able to. Further, when the pivot bracket 7 is attached, if the positioning flange 7e is joined to the upper end flange 2a of the cowl top panel 2, the positioning can be easily performed, and the man-hour for management for the positioning is significantly reduced.

Further, as shown in FIG. 3, at the time of a frontal collision of the vehicle, the air cleaner 15 and the like existing in the engine room ER press the air box B. In this case, the pivot bracket 7 is attached to the front end portion of the main body portion 7a and the mounting portion. Since it is an easy refraction part at the boundary with the piece 7d, it is easily refracted, while it is also refracted at the notch 13, 13 part which is the easy refraction part, and as a result, the notch 13, 13 part is turned around the fulcrum. It moves and escapes, and at the same time, the dash upper panel 1 is also crushed, and the collision energy is absorbed.

Thus, in the structure of the present invention, the pivot bracket 7 before the vehicle collision is sufficiently rigid, but at the time of a collision, the influence thereof is eliminated and the air box B is easily crushed.

In the above embodiment, the pivot bracket 7 is provided with the horizontal connecting portion 7c, but this is provided for the purpose of downsizing the pivot bracket 7 and may be omitted.

 FIG. 4 shows another embodiment of the present invention.

In this embodiment, long holes 16, 16 are used as the easily refracting portions instead of the notches 13, 13, and the function and effect are exactly the same as in the first embodiment.

〔effect〕

As described above, according to the present invention, in the structure in which the dash upper panel and the cowl top panel form an air box, and the reinforcing member having a vertical cross-section is provided at the inner rear end of the air box, From the front end of the main body part, a tilted flat plate-like main body part, a rear mounting piece part that is bent and extended from the rear end of the main body part, and is joined and fixed to the reinforcing member. The main body is formed by a front mounting piece that is bent and extends along the cowl top, and a positioning flange that is provided at the upper end of the front mounting piece and is joined to the upper end flange of the cowl top panel. Since the easily bendable portion is formed at the boundary between the rear part and the rear mounting piece, the rigidity of the pivot bracket can be improved without increasing the plate thickness, and the pivot bracket Effect that the Me-decided can either easily performed it.
