Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of a cowl outer panel of a vehicle.

Conventional technology The cowl outer panel of the vehicle was developed in 1986-56417.
As shown in the figure, it has a top plate that faces the cowl louver, and an outside air inlet is formed in this top plate.

Further, below the top plate portion 1, as shown in FIG. 4, a blower suction port 3 is installed at a location away from directly below the outside air inlet 2.

As a result, when the blower motor operates, outside air enters the blower suction port 3 through the cowl louver and the outside air inlet 2 due to the negative pressure, and finally enters the vehicle interior.

Problems to be Solved by the Invention However, since the peripheral edge of the conventional outside air inlet has a substantially geometrically correct shape, water that enters from the cowl louver during rain, etc. becomes water droplets 4 and forms the fourth water droplet. As shown in the figure, the air is transmitted toward the blower suction port 3 by the wind flowing from the outside air introduction port 2 toward the blower suction port 3.

That is, the water droplets 4 fall from the cowl louver onto the top plate 1 of the cowl outer panel, roll on the top plate 1 together with the outside air toward the outside air inlet 2, enter under the periphery of the outside air inlet 2, and enter the outside air inlet 2. As shown in FIG. 5, the air flows along its peripheral edge, reaches below the top plate 1, and is then sucked into the blower suction port 3.

If water droplets 4 enter the blower suction port 3, they will infiltrate into the vehicle interior. This is inconvenient because it impairs the comfort inside the vehicle.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a cowl outer panel of a vehicle having an outside air inlet in the top plate, which comes into contact with the wind flowing from the outside air inlet to the blower inlet in the cowl. A configuration is adopted in which a plurality of notches are provided on the periphery of the outside air inlet.

Function The water droplets that reach the outside air inlet reach one of the notches while flowing along the opening periphery of the outside air inlet, and at that notch they turn into larger water droplets and fall onto the cowl inner panel.

Therefore, there are no water droplets reaching directly above the suction port of the blower, and the inconvenience of water being sucked into the vehicle interior from the blower is eliminated.

Note that water droplets that have fallen onto the cowl inner panel are blocked by the upright wall of the blower suction port, and therefore do not flow into the blower.

Embodiment FIG. 1 shows an embodiment of a cowl outer panel according to the present invention.

In this figure, the same members as in FIG. 4 are designated by the same reference numerals.

The outside air inlet 2 has a substantially rectangular shape, and a large number of notches 5 are provided at equal intervals on the periphery of the outside air inlet 2 at locations where it comes into contact with the head wind from the outside air inlet 2 toward the blower suction port 3. The cutouts may also be provided at irregular intervals.

In this case, the notch 5 has a rectangular shape and is formed along two long sides 6 and 7 at the peripheral edge of the outside air inlet 2 and a short side 8 on the blower suction port 3 side. Of course, they may also be provided along other short sides 9.

Further, the shape of the notch 5 may be triangular as shown in the second figure, or circular as shown in the third figure.

As a result, the water droplet 4 is transferred to the notch 5 as shown in the first diagram.
At this point, the particles are stopped from moving forward, and there they become larger particles and fall downward, failing to reach above the blower suction port 3.

Effects of the Invention Since the present invention has the above-described configuration, it is possible to suitably prevent water from entering the vehicle interior even when the blower motor is started for ventilation during heavy rain or the like.

In addition, ventilation performance is not impaired in this case. Rather, the area of the outside air inlet increases, which is desirable in terms of improving ventilation.
