Description

The present invention relates to a deflector device for a vehicle that regulates traveling wind that tends to flow into a wheel house in which tires are accommodated.

    Conventionally, it is known that it is effective to restrict the running wind that flows into the wheel house to reduce the air resistance of the vehicle. As a conventional deflector device, for example, there is a structure shown in FIG. . That is, in the traveling wind coming toward the vehicle A from the traveling direction of the vehicle A, the lower surface of the vehicle body is placed in front of the tire B so as to regulate the traveling wind F ′ that tends to flow into the wheel house 5 that houses the tire B. A deflector plate E projecting substantially vertically downward from C is disposed.

    According to the prior art shown in FIG. 15, the deflector plate E is disposed in front of the wheel house 5 so as to extend in the vehicle width direction, thereby restricting the traveling wind F ′ from flowing into the wheel house 5. The air resistance of the vehicle can be reduced. As described above, the device for providing the deflector plate in front of the tire B and restricting the traveling wind F ′ to flow into the wheel house 5 increases the vertical height of the deflector plate E projecting from the lower surface C of the vehicle body to the road surface. It is known that the regulation effect increases as it gets closer, and the regulation effect increases as it gets closer to the tire B.

However, in such a structure, if the deflector plate E protrudes long downward from the lower surface C of the vehicle body, there is a risk that the deflector plate E may come into contact with obstacles such as curbs on the road surface and be damaged. There was a problem that the vertical height could not be sufficiently extended, and the regulation effect could not be sufficiently obtained for the traveling wind flowing into the wheel house.

    Further, as a similar technique, for example, as shown in Patent Document 1, an arrangement in which the airflow receiving surface is inclined with respect to the tire to improve the crosswind stability when the vehicle receives a crosswind is known. ing.

According to Patent Document 1, the airflow receiving surface is extended downward from the lower surface of the vehicle body, and the airflow around the tire flowing from the diagonally forward side of the vehicle body toward the tire is weakened so as to hit the tire.

  However, Patent Document 1 has the same problem as the conventional technique shown in FIG.

On the other hand, even if it touches obstacles such as curbs on the road surface, the spoiler that rotates and prevents breakage (Patent Document 2), the flexible spoiler that prevents breakage by bending, etc. Has been proposed (Patent Document 3).
