Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the structure of the front body of an automobile, and more specifically, to the structure of a drain port in the cowl side provided at the front of the automobile body.

(Prior Art) In a conventionally known front body structure of an automobile, that is, a drain port structure in a cowl side, an opening is formed between the outer edge of the cowl side and the outer edge of a dash panel that constitutes the bottom surface of the cowl side. A drainage outlet has already been proposed (for example, see Japanese Utility Model Application No. 57-47573).

(Problems to be solved by the invention) When an opening is formed between the outer edge of the cowl side and the outer edge of the dash panel constituting the bottom surface of the cowl side, as in the above-mentioned known example, the formation of the opening As a result, the strength of the cowl side decreases, so it is necessary to develop a structure that can prevent this decrease in strength.

This invention was made in view of the above points,
The purpose is to improve the strength of the drain structure on the cowl side.

(Means for Solving the Problems) In the present invention, as a means for solving the above problems, an air intake box formed by a cowl panel and a dash panel that extends in the vehicle width direction, and an air intake box that extends in the longitudinal direction of the vehicle body. A first closed section extending in the longitudinal direction of the vehicle body formed between the cowl side outer and the cowl side inner is communicated through an opening formed at the joint between the cowl side inner and the dash panel. 1. A drainage channel is formed in the closed cross section for discharging water flowing from the air intake box, and
A reinforcement consisting of a vertical wall portion and a bottom surface portion is disposed within the first closed cross section to form a second closed cross section extending in the longitudinal direction of the vehicle body between the cowl side outer and the cowl side outer. The upper end of the vertical wall portion and the outer end of the bottom surface portion are respectively joined to the upper end and lower outer end of the cowl side outer, while the bottom surface portion of the reinforcement is provided with a portion that protrudes upwardly in a portion corresponding to the drainage channel and is connected to the outer end of the cowl side outer. A bead portion extending in the width direction is formed.

(Function) In the present invention, the following effects can be obtained by the above means.

That is, the water that has entered the air intake box is discharged to the outside from the drainage channel formed within the first closed cross section, but the water that has entered the air intake box is discharged to the outside from the drainage channel formed within the first closed cross section. The bead portion extending in the vehicle width direction formed in the portion corresponding to the drainage channel reinforces the structure of the drainage channel portion on the cowl side, resulting in an extremely robust cowl side structure.

In addition, by forming a second closed section extending in the longitudinal direction of the vehicle body within the first closed section using reinforcement, the rigidity of the cowl side is improved, and the cross-sectional shape is less likely to collapse due to bending, especially in the event of a head-on collision. .

Furthermore, by forming the bead portion on the bottom surface of the reinforcement, the second closed section and the drainage channel are cut off, and corrosion of the inner wall of the second closed section by water is prevented.

Furthermore, due to the formation of the bead portion, the second closed cross section has a continuous shape without being opened, so that the rigidity of the drainage channel portion where stress concentration is likely to occur is strengthened.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

In this embodiment, the structure of the joint portion between the cowl 2 and the cowl side 3 in the front part of the vehicle body 1 of an automobile will be explained (see FIG. 2).

As shown in FIG. 1, an air intake box 6 extending in the vehicle width direction is formed in the cowl 2 by a cowl panel 4 and a dash panel 5, both of which extend in the vehicle width direction. The air intake box 6 constitutes an air passage for guiding air taken in from an air intake port 7 formed in the cowl panel 4 to the passenger compartment side.

On the other hand, the cowl side 3 is composed of a cowl side outer 8 and a cowl side inner 9, both of which extend in the longitudinal direction of the vehicle body, and a first closed section 10 extending in the longitudinal direction of the vehicle body is formed between them. Note that the bottom surface of the cowl side 3 is constituted by the dash panel 5.

Then, the air intake box 6 and the first
The closed cross section 10 refers to the opening 11 formed at the joint between the dash panel 5 and the cowl side inner 9.
It is communicated by. In this embodiment, the opening 11 is formed by recessing the end of the cowl side inner 9, but it may also be formed by recessing the dash panel 5 side.

Further, in the first closed section 10, there is a drainage channel 12 for discharging water W that enters the air intake box 6 from the air intake port 7 and flows in through the opening 11 to the outside of the cowl side 3. is formed.

Further, within the first closed section 10, a reinforcement 13 extending in the longitudinal direction of the vehicle body is disposed to form a second closed section 14 extending in the longitudinal direction of the vehicle body together with the cowl side outer 8. The reinforcement 13 includes a vertical wall portion 13a and a bottom surface portion 13b, and the upper end of the vertical wall portion 13a and the outer end of the bottom surface portion 13b are connected to the cowl so as to divide the first closed section 10 into two. side outer 8
It is joined to the upper end and outer end of the .

In the bottom portion 13b of the reinforcement 13, a bead portion 15 is formed in a portion corresponding to the drainage channel 12, projecting upward and extending in the vehicle width direction. The bead portion 15 has the function of reinforcing the rigidity of the drain channel 12, particularly the outlet portion of the drain channel 12 (ie, the drain port 12a).

In the drawings, reference numeral 16 indicates a front fender outer, 17 indicates a front fender inner, and 18 indicates a front pillar.

By configuring as above, the air intake port 7
Water that entered air intake box 6 from
is connected to the drain port 12 via the opening 11 and the drain channel 12.
It is discharged to the outside from a.

Since a second closed section 14 extending in the longitudinal direction of the vehicle body is formed within the first closed section 10 by the reinforcement 13 disposed within the first closed section 10, the cowl side 3 itself has rigidity. As a result, the cross-sectional shape is less likely to collapse due to bending, especially in the event of a head-on collision.

In addition, because the second closed section 14 has a continuous shape without being opened due to the bead portion 15 formed in the reinforcement 13, the drainage channel 12, where stress concentration is likely to occur, is also strengthened.
This results in an extremely robust cowl side structure.

Furthermore, by forming the bead portion 15 on the bottom surface portion 13b of the reinforcement 13, the second
The closed section 14 and the drainage channel 12 are blocked, and corrosion of the inner wall of the second closed section 14 due to water is prevented.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that the design can be changed as appropriate without departing from the gist of the invention.

(Effect of the invention) As described above, according to the invention, there is a space between the cowl side outer and the cowl side outer in the first closed section extending in the longitudinal direction of the vehicle body formed between the cowl side outer and the cowl side inner. The second section extends in the longitudinal direction of the vehicle body.
A reinforcement is disposed to form a closed cross section, and a portion of the bottom surface of the reinforcement corresponds to a drainage channel formed within the first closed cross section and communicating with an air intake box extending in the vehicle width direction. Since a bead portion is formed that projects upward and extends in the vehicle width direction, the first closed cross section is divided into two by the rainforment disposed within the first closed cross section, whereby the cowl side itself is divided into two parts. The rigidity is strengthened, and the cross-sectional shape is less likely to collapse due to bending, especially in the event of a head-on collision, increasing the absorbed load.The bead formed on the reinforcement also strengthens the drainage channel. This has the practical effect of providing an extremely robust cowl side structure.

In addition, since the bead portion is formed on the bottom of the reinforcement so that the second closed section and the drainage channel are cut off, corrosion of the inner wall of the second closed section by water is prevented, and durability is improved. It also has the effect of greatly contributing to improvement.

Furthermore, due to the formation of the bead, the second closed cross section has a continuous shape without being opened, so it is necessary to increase the rigidity (especially the cross-sectional rigidity to prevent deformation of the cross-sectional shape) in the drainage channel where stress concentration is likely to occur. ) is strengthened, which also has the effect of preventing a decrease in the rigidity of the cowl side.
