Description

[Detailed Description of the Invention] This invention relates to a ventilation passage structure for an automobile body, and particularly to an exhaust passage structure thereof.

First, an example of an exhaust passage structure in a conventional vehicle ventilation system will be explained with reference to FIGS. 1 and 2.

After the fresh air introduced into the single cabin ventilates the cabin, it normally exits through the inner wall opening at the rear of the cabin and between the inner and outer walls.In the case shown, the side inner panel 1 It passes through a discharge opening 2 drilled in the lower part of the window near the rear end and flows into the layer space 4 sandwiched between the side inner panel 1 and the side outer panel 3.

Therefore, an exhaust opening (not shown) leading from the layer space 4 to the outside is bored in the outer panel near the bottom of the center pillar 5, and it is necessary to prevent lumps etc. Because the outside air contains a lot of swirl,
If the exhaust opening is provided at the rear of the vehicle body, the exhaust opening and the air passage near the opening are likely to become clogged.

Therefore, the air flow that has entered the layered space 4 flows in the layered space 4 toward the front of the vehicle body, and then is exhausted to the outside from the above-mentioned exhaust opening.

However, with the above-mentioned conventional ventilation passage structure, the exhaust opening is easily noticeable from the outside, which not only spoils the appearance of the vehicle body, but also allows foreign matter such as muddy water to enter through the exhaust opening, causing damage to the structure. It has the disadvantage of accelerating deterioration.

The present invention has been made in order to eliminate the above-mentioned drawbacks. Namely, the purpose of the present invention is to provide a ventilation passage structure for an L/vehicle body that does not impair the appearance of the vehicle body and does not adversely affect the vehicle body. It's about doing.

Hereinafter, the present invention will be explained based on one embodiment shown in the drawings.

FIG. 3 is a diagram showing the structure of the embodiment cut along the vertical line of the center pillar 5 portion, that is, the line A-A. As shown in the figure, an exhaust opening 8 is located near the lower end of the inner panel 7 of the center pillar 6.
is opened, and the inner panel 7 is in contact with the opening 8.
A duct 9 that opens upward into the layer space 4 between the center pillar outer panel 10 is welded to the outer surface of the duct 9, and a drain plate 11 is fixedly installed in the middle of the duct 9. .

By the way, the external space 12 that the exhaust opening 8 is in contact with has: (a) its upper surface is the pantry pan 13 (b) its rear surface is the rising part 4a of the floor panel 14 (C) its front surface is the front wheel nozzle・Usu rear plate 1
5, and mat guard 16 (d) The inner surface of the main body is a space 12 that is open at the bottom and surrounded by the shield panel 17 of the engine E room, etc. When the vehicle is running, this space 12 is - Negative pressure is generated.

The rear part of the wheel house to which the front wheel 18 is attached is formed by the front overhang 14b of the floor panel 14, the house rear plate 15, and the seal panel 1γ.

Here, the passage structure of the embodiment includes both the above-mentioned conventional discharge opening 2 and the above-mentioned exhaust opening 8,
Therefore, the air inside the vehicle is sucked by the strong negative pressure generated below the rear of the front wheels, and is
The layer space 4→duct 9→exhaust opening 8→external space 12→external air is flown through the thread path without delay.

Note that the exhaust opening 8 is in direct contact with the outside air as in the conventional structure, so there is no risk of muddy water or dust entering the opening 8.

As described above, according to the ventilation passage structure of the vehicle body according to the present invention, the exhaust opening is provided on the recessed inward panel surface at the rear and lower part of the front wheel house, so that the air inside the vehicle interior is removed while the vehicle is running. In addition to effectively discharging the water to the outside, it has practical effects such as preventing the body structure from being adversely affected by muddy water and the like, and also improving the appearance of the body by making the surface of the body uniform.

Claims (1)

[Scope of utility model registration request] In the car body structure, the layered space sandwiched between the outer and inner panels on the side of the car body is used as a passageway for ventilation of the passenger compartment, and the air coming out of the passenger compartment is guided to the layered space near the center pillar. At the same time, an exhaust opening is drilled near the lower end of the inner panel at this point, so that the air that has passed through the layer space is discharged to the rear and lower part of the front tire house through the opening. A vehicle body ventilation passage structure characterized by being formed in an L shape.
