Description

[Detailed description of the invention] This invention relates to a waterproof structure for a cowl panel of an automobile.

Generally, the outside air introduced into the cabin of a car is taken in through a number of slits arranged in parallel in the vehicle width direction in the cowl panel, and passes through a passage provided in the drip guard below the slits.
Furthermore, the vehicle interior is accessed through a ventilator vent provided in the bulkhead below.

Since rainwater and car wash water inevitably enter through the slits in the cowl panel along with outside air, the drip guard prevents this water from entering the ventilator vent.

The present invention is designed to effectively perform air and water separation in such a ventilation structure, and the structure will be explained below with reference to an embodiment shown in the drawings.

The cowl panel 1 is connected to the front lower part of the front window glass 2 and is located at the rear of the front hood 3.

This cowl panel 1 has many ventilation sleeves in the vehicle width direction.
la are drilled in parallel.

A drip guard 4 is arranged below the cowl panel 1, and a duct chamber 5 is formed in the lower part of the drip guard 4.

The duct chamber 5 has a closed section shape with a drip guard 4 at the top, a duct panel 6 at the front, and a front bulkhead 7 from the bottom to the rear. is the provision.

The drip guard 4 is provided opposite to the ventilator ventilation lower a, so as to form an eaves section. However, in the present invention, the opposing portion 4a of the drip guard 4 located above the ventilator ventilation lower a is connected to the vehicle. It has a mid-height shape in the width direction, and extension parts 4b are provided at both ends of the facing part 4a, so that it is long enough to correspond to at least the entire width of the ventilation sleeve (la) provided on the cowl panel 1 in the vehicle width direction. It's a formality.

Furthermore, a louver 4C is provided in the drip guard 4, but this louver 4C is not provided in the opposite part 4a, but in the extended part 4b.
There are an equal number of pieces in parallel.

The cut-off end 4d of the louver 4C is inclined so that the intruding water flows down and scatters in the vehicle width direction.

That is, the infiltrated water 8 entering from the ventilation sleeve Ha hits the drip guard 4.

Since the opposing portion 4a of the drip guard 4 has a mid-height shape, the infiltrating water 8 flows along the upper surface of the opposing portion 4a as a flow 8a in the vehicle width direction.

Then, it falls into the duct chamber 5 from the louver 4e of the louver 4C, which is closest to the opposing portion 4a.

At this time, since the open end 4d of the louver 4e is inclined in the vehicle width direction, the infiltrating water 8 flows along the open end 4d.
The water becomes a flow 8b like a film of water, and is inclined in the vehicle width direction and scattered downward.

Of the louvers 4C, louver 4f is closer to the vehicle width than louver 4e.
The intruding water 8 from the ventilation slit 1a also hits the vent slit 1a, but since the cut-off end 4d of the louver 4f is also inclined in the vehicle width direction, the intruding water 8 flows down in that direction.

Further, when the infiltrating water 8 from the louver 4f hits the film-like flow 8b of water from the louver 4e, it merges with this flow 8b and flows down.

In this way, the infiltrated water 8 always exists on the vehicle width side of the flow 8b in the duct chamber 5 and does not reach the ventilator ventilation lower a, so the infiltrated water 8 does not mix into the outside air entering from the ventilator ventilation lower a. do not have.

As mentioned above, in the present invention, the part of the drip guard that faces the ventilator vent is formed with a medium height, and both ends of the drip guard are extended to correspond to the ventilation slits provided in the cowl panel. Since the louver is bored away from the part facing the opening, and the cut-off end is slanted in the vehicle width direction, intruding water will not enter the ventilator vent, and air and water will be separated sufficiently. It will be done.

In other words, it has the advantage of providing an effective waterproofing effect despite its simple structure.
