Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an air intake lever of a vehicle, and more particularly to a draining structure thereof.

[Prior Art] In a one-box vehicle or the like, as an air intake means to the engine, an air introduction opening is provided in an outer plate on the side surface of the vehicle body, and a means for communicating this with the engine by a duct is adopted. The air intake louver 2 is attached so as to cover it as shown in FIG. In addition,
In the figure, 1 is an outer plate, E is an engine, and 5 is a duct.

In such an intake structure, rainwater may be sucked in mixed with the intake air. As the rainwater to be sucked in, a relatively large amount of rainwater flows along the vehicle outer plate and flows into the air intake louver (hereinafter, simply referred to as a louver) during rainfall. That is, FIG. 12 shows a mounting structure for the upper part of the louver, in which rainwater flows down from the outer plate 1 to the outer surface of the upper part of the louver 2 and is slit.
It reaches the upper edge of 21 and is sucked into the duct 5 along with the air along the upper surface of the slit 21. 50 in the figure
Is a seal packing, and the end of the duct 5 is used in the illustrated example.

As a means to reduce the mixture of rainwater, there is a means to reduce the air suction pressure by forming a volume expansion part in the middle part of the duct, but there is a problem that it is not possible to significantly reduce it and noise is likely to occur at the expansion part. . Further, a means for bending and deforming the shape of the duct to collide the intake rainwater with the wall of the duct has been taken, but rainwater remains in the duct and cannot be an essential solution.

[Problems to be solved by the present invention] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a louver mounting structure that prevents rainwater that has flowed down a vehicle outer plate from entering the louver. To do.

[Means for Solving the Problems] As shown in FIGS. 3 to 5, the present invention provides an air introduction opening 10 of the vehicle body skin 1 and an outer peripheral portion of the louver 2 which is flush with the general surface of the vehicle body skin 1. An annular seal packing 50 interposed between the seal packing 50 and an outer edge 1 surrounding the seal packing 50 and a louver 2 sandwiches the seal packing 50 to form a rain gutter 4 around the outer periphery of the louver. A rainwater inlet 3 communicating with the upper part of the rain gutter 4 is formed along the rain gutter 4, and the rain water flowing down the vehicle body outer plate 1 is formed in the rain gutter 4 at the upper end of the rain water inlet 3 with an inclined surface that obliquely descends in the vehicle interior direction. It is characterized in that a rib 31 for guiding to is provided.

[Operation and Effect] Rainwater flowing down the vehicle outer plate 1 is provided with ribs 31 of the rainwater inlet 3.
Follow along and enter the upper part of Rain Gutter 4. Then, the rainwater flows along the rain gutter 4 on the outer periphery of the seal packing 50 and is drained downward to be drained.

[Embodiment] As shown in FIG. 1, a side panel 1 of a one-box type vehicle.
A louver 2 is attached to the. An air introduction opening is formed in the outer plate 1 on the back surface side of the louver 2, and the air introduction opening communicates with the engine E through a duct 5.

2 to 6 show an embodiment of the present invention. The louver 2 is made of synthetic resin, and as shown in FIG. 2, intake ports slits 21 are formed in a plurality of upper and lower stages. A rib 22 is formed on the back surface side around the inlet slit 21 as shown in FIGS. 3, 4, and 6. At the top of the louver 2 is a rainwater inlet 3 that has almost the same shape as the inlet slit 21.
Is formed. A rib 31 is formed at the upper edge on the back surface side of the rainwater introduction port 3 so as to incline obliquely downward toward the inside to form a rainwater guide surface 30.

On the other hand, as shown in FIG. 3 to FIG.
An air introduction opening 10 is formed in the. An opening edge 11 of the outer plate 1 around the air introduction opening 10 is concave as compared with a general surface of the outer plate. Along the air introducing opening 10, a terminal 50 of the duct 5 made of rubber or soft synthetic resin is annularly attached. The end 50 of the duct 5 has a large thickness and serves as a seal packing.

The louver 2 is arranged so as to cover the air introduction opening 10 of the outer plate 1, and one side end having a V-shaped cross section is fixed to the door opening edge 12 of the outer plate 1 with a screw. Although not shown, a protrusion is formed on the other side end of the louver 2, and this protrusion is fitted into the recess formed in the outer plate 1. The outer surface of the louver 2 is flush with the general surface of the outer plate 1 in the mounted state.

By attaching the louver 2, the seal packing 50 along the air introduction opening 10 is located at a position surrounding the intake slit 21.
It is pressed against and has a sealing function of blocking the introduction opening 10 from the outer periphery thereof. Then, on the outer periphery of the seal packing 50,
A groove-shaped rain gutter 4 is formed between the louver 2 and the outer plate 1. At the upper end of the louver 2, the outer edge 23 is flush with the outer panel 1 with a slight gap a, and the rainwater inlet 3
Is connected to the upper part of the rain gutter 4 and the rainwater guide surface 30 forming the upper surface of the inlet 3 is an inclined surface descending from the upper end outer surface 23 toward the outer plate concave surface. One side end of the louver 2 which is screwed is covered by the door D when the door is closed as shown in FIG. Then, in the louver 2 attached to the air introduction opening 10 of the outer plate 1 as described above, when the vehicle is traveling in the rain, rainwater flowing down the outer plate 1 will be as shown in FIG. 2, FIG. 4 to FIG. As indicated by an arrow W ₁ , it flows from the outer plate 1 to the outer surface 23 of the edge of the louver 2, and is guided by the rainwater guide surface 30 to flow into the upper part of the rain gutter 4. And the rainwater W ₂ accumulated on the upper part flows down along the rain gutter 4 in the direction of the arrow W ₃ ,
A part of the flow is eliminated as it is along the outer plate 1 as indicated by an arrow W ₄ , and a part of the part is circulated under the rain gutter 4 as indicated by an arrow W ₅ and eliminated.

During rainy weather, a majority of the rainwater flowing into the duct 5 is due to the rainwater flowing down the outer plate 1, and the rainwater flowing into the duct 5 is greatly reduced by the structure of the present invention. Further, since the rain gutter 4 is formed by the groove between the opening edge 11 of the outer plate 1 and the inner peripheral surface of the louver 2 that sandwich the seal packing 50, the general surface of the outer plate 1 and the outer peripheral portion of the louver 2 are flush with each other. It is continuous and looks good.

In a vehicle that has an intake opening to the engine on the outer plate,
Since the majority of the rainwater mixed in the intake air is the rainwater that flows down through the outer plate, the present invention can prevent this runoff rainwater from mixing.
