Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to the body structure of a cowl portion for an automobile.

[Prior art] In recent years, with the development of expressways, opportunities to drive at high speeds have increased, and the influence of running resistance at high speeds cannot be ignored. Efforts are being made to improve the characteristics.

However, as the inclination angle of the front window panel becomes smaller, the effective space inside the vehicle becomes smaller.
As seen in Publication No. 122972, proposals have been made to improve aerodynamic characteristics while securing effective space within the vehicle interior.

That is, as shown in FIG.
A housing-shaped air box 105 having an air introduction hole 103 is provided directly below the air box 1.
A mounting panel 109 is extended and protruded forward from 05, with which the hood 107 comes into elastic contact when closed. The pivot portion 113 of the hyper 111 is mounted and supported on the mounting panel 109.

[Problems to be solved by the invention] In this structure, since the air box 105 has a supporting function of supporting the hood 107 when closed, it is necessary to arrange it on an extension of the front window glass 101 as shown by the chain line. .

If the air box 105 is placed on the extension line of the front window glass 101, the space L in the engine room becomes narrower, so it is placed in the conventional position (solid line).
An air box 105 is disposed at the air box 105, and the hood 107 is supported by a mounting panel 109 extending from the air box 105.

However, the mounting panel 109 that supports the hood 107 is cantilevered, and the wiper 11
Since the first pivot portion 113 is mounted and supported, this is not desirable in terms of support rigidity.

Therefore, this invention provides a body structure for an automobile cowl part that can ensure support rigidity of the wiper mounting part and at the same time protect auxiliary parts such as wire harnesses routed along the cowl box. There is a particular thing.

[Means for Solving the Problems] In order to achieve the above object, this invention supports the lower end side of the front window panel, and has an intake port for introducing outside air on one side, and an intake port for introducing outside air on the other side. A cowl box with a box-shaped cross section and an outlet leading to the cowl box is provided along the width direction of the vehicle, a pivot portion of the wiper is mounted and supported on the cowl box, and a cowl top grill is provided on the upper surface of the cowl box. An extension protrusion is provided at the front end of the top grill, extending forward from the front end of the cowl box and coming into elastic contact with the hood when closed.
A vertical part is provided on the back surface of the extended protrusion, which has a gap with the front end vertical wall of the cowl box, and whose distal end faces and is close to the vehicle body side member, and the gap is used as an auxiliary component wiring space.

[Embodiment] Hereinafter, an embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 and 2.

In the figure, reference numeral 1 indicates a cowl box that is long in the width direction of the vehicle and supports the lower end of the front window panel 3 (glass).

The cowl box 1 is formed into a box-like cross section by overlapping and joining the ends 9, 9 of the cowl top panel 5 and the dash upper panel 7, and has an intake port 1 on the upper surface of the cowl top panel 5 for introducing outside air.
1 is provided. Further, the dash upper panel 7 is provided with an outlet 13 at a position offset from the intake port 11, and the outlet 13 continues into the vehicle interior.

On the upper surface of the cowl top panel 5 where the intake port 11 is provided, there is a cowl top grille 1 made of synthetic resin that covers the upper surface of the panel in the width direction of the vehicle.
5, and a wiper 17 for wiping the panel surface of the front window panel 3.

The cowl top grill 15 is formed along the width direction of the vehicle, covers the upper surface of the cowl top panel 5, and is provided with a plurality of slits 19 at a portion corresponding to the intake port 11. This allows outside air to be introduced into the cowl box 1 through the slit 19.

Further, the front end 21 of the cowl top brill 15 is provided with an extension projection 40 extending forward and upward from the front end position of the cowl box 1. The extension protrusion 40 functions as a support member for the hood 25, and the upper edge is provided with a support member for the hood 25 when the hood 25 is closed.
A weather strip 23 that makes elastic contact with the weather strip 5 is attached. Further, from the back surface of the extension projection 40, a hanging portion 39 is extended downward with a distance from the vertical wall portion 38 located at the front end of the cowl top panel 5, and the lower end serving as the extension end is a dazzling portion. It is close to the tip of the upper panel 7.

The hanging portion 39 functions as a strength member for the extension projection 40 against input from above, and furthermore, the vertical wall portion 38 of the cowl top panel 5 and the hanging portion 39 are connected to the wire harness 41. This is an auxiliary component wiring space 30 in which auxiliary components such as the following are wired. This allows it to function as a protector at the same time.

On the other hand, the pivot portion 27 of the wiper 17 is fixedly supported at a reasonable angle θ substantially perpendicular to the upper surface of the cowl top panel 5. The upper end side of the pivot portion 27 projects upward from the cowl top grille 15, and an arm 29 is attached to the pivot shaft of the projecting pivot portion 27. The arm 29 is equipped with a blade 31 for wiping the window panel surface.
is installed. Further, the lower end of the rotating shaft is conductively connected to the output shaft of the wiper motor M via a drive mechanism 33.

In addition, 35 indicates a darts lower panel.

With this structure, the wire harness 41 is protected by the vertical portion 39 when a load is input from the outside. Further, since the pivot portion 27 of the wiper 17 is mounted on the upper surface of the box-shaped cowl box 1 with increased support rigidity, a reliable mounting state can be obtained. In addition, since the pivot portion 27 is attached at an angle of 90° perpendicular to the upper surface of the cowl top panel 5, the attachment is not strained.

On the other hand, outside air is taken into the rubbox 1 through the slit 19 and introduced into the vehicle interior through the outlet 13.

Moreover, when the hood 25 is opened, the upper surface of the cowl top panel 5 is covered by the cowl top grill 15, so that the appearance is not spoiled.

[Effects of the Invention] As explained above, according to this invention, the pivot portion of the wiper can be attached to the cowl box with high support rigidity, so that a supported state with high support rigidity can be obtained. Also, as a strong member,
In addition, due to the vertical part that functions as a protector,
Even if a load is input from the outside, damage to the extension protrusion can be prevented, and auxiliary components such as a wire harness can be protected.
