BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front body structure of an automobile, and more particularly to a drainage structure for draining water flowing through a cowl portion of the automobile.

[0002]

2. Description of the Related Art In the front part of an automobile, a cowl portion is arranged along the lower part of the windshield, and water (rain water, washing water, etc.) flowing into the cowl portion is discharged to the outside of the vehicle. Conventionally, various structures have been adopted.

FIG. 3 shows a conventional example of a front body structure of an automobile. This front body structure is located on both sides of a cowl top panel 31 arranged along a lower portion of a windshield 30. That is, the flowing water passage 33 connected to the engine room 32 is provided in the vicinity of the pair of left and right hinge members 34 that rotatably support the front hood 33.

In this case, the windshield 3
The water flowing from 0 to the cowl top panel 31 is
As shown by a broken line a in FIG. 3, the engine room 3 is guided to the running water channels 33 on both sides of the cowl top panel 31.
It is drained onto the suspension strut storage portion 35 in the No. 2.

4 to 6 show another conventional example different from the above. In this example, a pair of left and right hood hinge brackets 36 to which a hinge member 34 of a front hood 33 is rotatably mounted. A hole 37 is formed in the hole 37, water is guided through the hole 37 onto the cowl top lower panel 38, and water is discharged through an outlet 40 provided between the side of the cowl top lower panel 38 and the apron upper panel 39. The water is drained to the outside of 41.

That is, in the case of this conventional example, the water guided to the left and right side portions of the cowl top panel 31 is placed on the tip portion of the apron upper panel 39 as shown by the broken line b in FIGS. 5 and 6. It is dropped onto the attached hood hinge bracket 36, guided through the hole 37 of the hood hinge bracket 36 onto the cowl top lower panel 38, and then drained toward the fender panel 43 through the drain port 40 on the side of the cowl portion 42. It has become so.

In FIG. 5, 44 is a cowl upper panel, 45 is a dash panel, and 46 is an air duct provided between the cowl upper panel 44 and the cowl top lower panel 38 at the upper end portion of the dash panel 45.

However, the conventional structure as described above has the following problems. That is, in the case of the structure shown in FIG. 3, since water is poured into the engine room 32, various automotive electrical components arranged in the engine room 32 may be adversely affected by water. There is. Moreover, since it is necessary to provide the running water channel 33 on the side portion of the cowl top panel 31,
The press work is troublesome. In addition, the water flows into the water channel 33.
However, there is a problem in that it accumulates in the middle of the process (for example, the part indicated by the symbol P in FIG. 3) and causes the generation of rust.

Further, in the case of the structure shown in FIGS. 4 to 6,
Since the water is guided onto the cowl top lower panel 38, water may flow between the cowl top lower panel 38 and the cowl upper panel 44, and the water may enter the air duct 46.

The present invention has been made in order to solve such a problem, and its object is to simplify the construction without the need to form a flowing water channel on the side portion of the cowl top panel. The water can be drained directly to the outside so that it does not adversely affect the electric parts of the vehicle by flowing into the engine room, and it is possible to prevent rusting due to water pools and water from entering the air duct. It is to provide a front body structure of an automobile.

[0011]

In order to achieve the above object, in the present invention, a drain hole is formed in a hood hinge bracket that rotatably supports a front hood, and a through hole is formed in an apron upper panel. The water drain port is formed in such a manner that the water drain port is communicated with the through port so that the water drain port is opened toward the outside of the apron upper panel, and the water guided to the hood hinge bracket is the water. The drainage is configured to drain to the outside of the apron upper panel.

[0012]

[Function] Since the water drain port formed in the hood hinge bracket is opened to the outside of the apron upper panel through the through hole of the apron upper panel, water flows through the water drain port to the outside of the apron upper panel, that is, It will be drained to the outside of the engine room.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will now be described with reference to FIGS.
Will be described with reference to.

1 and 2 show a front body structure of an automobile according to the present invention. In FIG. 1, 1 is a cowl portion, 2 is a front hood, and 3 is a front hood 2 which is rotatable. A hinge member for supporting 4, a hood hinge bracket for attaching the hinge member 3 to the vehicle body, 5 an apron panel, 6 an apron upper panel joined to the upper part of the apron panel 5, and 7 an outside of these panels 5, 6. It is a fender panel that is arranged to face.

The cowl portion 1 described above, as shown in FIG.
The cowl top panel 8, the cowl top upper panel 9, and the cowl top lower panel 10 are joined to each other in a closed cross-sectional shape, and the hood hinge bracket 4 is disposed corresponding to the side portion of the cowl portion 1. Further, the hood hinge bracket 4 is formed with a drain hole 11 formed of a through hole, and the apron upper panel 6 is formed with a through hole 12. The water drainage port 11 of the hood hinge bracket 4 is opened outward through the through hole 12 of the apron upper panel 6 in the following configuration.

That is, as clearly shown in FIG. 2, one end 4a of the hood hinge bracket 4 is joined to the upper end 6a of the apron upper panel 6 and fastened together with the hinge member 3, so that the hood hinge bracket 4 has The other end 4b
Is joined to the side portion 10a of the cowl top lower panel 10. Then, the peripheral portion of the water drainage port 11 of the hood hinge bracket 4 is the through hole 1 of the apron upper panel 6.
The water drainage hole 11 is connected to the through hole 12 by being combined with the peripheral edge of the two in a state of being overlapped with each other, whereby the water drainage port 11 is connected to the through hole 12 and the apron upper panel. 6 is open to the outside.

Therefore, the water drainage port 11 is opened inside the fender panel 7 so as to face the fender panel 7, and the hood hinge bracket 4 itself is configured as a water passage. For this reason, the water passage communicates only with the outside of the apron upper panel 6 through the water draining port 11, and does not communicate with the engine room 13 at all.

Further, the water drainage port 11 is disposed below the side portion 10a of the cowl top lower panel 10, and the location where the drainage port 11 is disposed is the air duct 1 provided inside the cowl portion 1.
It is configured so as to be located at a position more lateral than 4 (see FIG. 2). Therefore, the structure is such that the water flowing into the hood hinge bracket 4 does not enter the air duct 14.

According to the front body structure of the automobile having such a structure, the water flowing along the cowl top panel 8 is guided to the hood hinge bracket 4 and is guided to the outside of the apron upper panel 6 through the drain port 11. Since the water is drained to (the portion between the apron upper panel 6 and the fender panel 7), there is no possibility that water will enter the engine room 13 and impinge on the electric parts of the vehicle.

It is possible to prevent the accumulation of water in the engine room 13 and prevent the generation of rust due to the accumulation of water. further,
There is also no risk of water getting into the air duct 14 provided in the cowl portion 1.

Further, since the running water channel 33 (see FIG. 3) is not provided on the side portion of the cowl top panel 8, the cowl top panel 8 can be simplified in shape, and the cowl top panel 8 can be press-formed. It can be facilitated.

The embodiment of the present invention has been described above.
The present invention is not limited to this embodiment, and various modifications and changes can be made based on the technical idea of the present invention. For example, in the above-described embodiment, the peripheral edge of the water drainage port 11 of the hood hinge bracket 4 is joined to the peripheral edge of the through hole 12 of the apron upper panel 6, but the invention is not limited to this. The water drainage port 11 may be opened toward the outside of the apron upper panel 6 by further extending the peripheral edge portion and arranging it through the through hole 12.

[0023]

As described above, according to the present invention, the water drain port formed on the hood hinge bracket is connected to the through hole formed on the apron upper panel so that the water drain port is located outside the apron upper panel. Open towards
Since the water is drained to the outside of the apron upper panel from the drain port, the water is drained to the outside of the engine room without entering the inside of the engine room. Therefore, according to the present invention, it is possible to avoid a situation where water is splashed on the electric components of the automobile in the engine room to exert an adverse effect.

Moreover, by adopting the construction in which the water is directly drained to the outside, it is possible to prevent the accumulation of water in the inside of the engine room, etc. and prevent the generation of rust due to the water accumulation, and to prevent the water from flowing into the air duct provided in the cowl portion. It is possible to prevent a situation where a person enters.

Further, since it is not necessary to form a flowing water channel on the cowl top panel, the shape of the cowl top panel can be simple and therefore its press molding becomes easy.
