Abstract

In a vehicle air guide path structure, a vertically long air guide path forming member is provided along an outer edge of a side surface portion of a vehicle body on a rear side of a wheel house. A vertically long air guide path is formed at the rear side of the wheel house. The vertically long air guide path suctions air from the wheel house and exhausts air along a side surface of the vehicle body. A partition member partitions the vertically long air guide path so as to form a plurality of sections in an upper-lower direction. A vertically long inclined surface is formed on the side surface portion of the vehicle body at a rear side of the vertically long air guide path. The partition member protrudes to a rear side from the vertically long air guide path.

First claim

What is claimed is:

1. A vehicle air guide path structure in which a vertically long air guide path forming member is provided to be vertically long along an outer edge of a side surface portion of a vehicle body of a vehicle on a rear side of a wheel house of the vehicle, a vertically long air guide path is formed by the vertically long air guide path forming member at the rear side of the wheel house, and the vertically long air guide path is configured to suction air from the wheel house and exhaust air along a side surface of the vehicle body, the vehicle air guide path structure comprising:
a partition member that partitions the vertically long air guide path so as to form a plurality of sections in an upper-lower direction,
wherein a vertically long inclined surface is formed on the side surface portion of the vehicle body at a rear side of the vertically long air guide path, and
wherein the partition member protrudes to a rear side from the vertically long air guide path,
wherein the partition member includes:
an inclined portion that is lowered forward toward an introduction port of the vertically long air guide path; and
a flat portion that extends from a rear end of the inclined portion along a front-rear direction of the vehicle body.

2. The vehicle air guide path structure according to claim 1 ,
wherein the flat portion protrudes to a rear side from the vertically long air guide path.

3. The vehicle air guide path structure according to claim 2 ,
wherein the vertically long air guide path forming member includes:
an inner member located at an inner side of the vertically long air guide path in a vehicle width direction of the vehicle; and
an outer member located at an outer side of the vertically long air guide path in the vehicle width direction,

wherein a facing inclined surface that follows the vertically long inclined surface is formed on a rear end edge portion of the outer member.

4. The vehicle air guide path structure according to claim 3 ,
wherein a wheel house member that forms the wheel house includes:
a through hole formed in a portion overlapping an introduction port of the vertically long air guide path; and
a funnel portion erected along a peripheral edge of the through hole, and

wherein the funnel portion is provided in a state in which the funnel portion enters the introduction port.

5. The vehicle air guide path structure according to claim 3 , wherein the vertically long air guide path is formed from a lower side of an axle center of the wheel house to an upper side of the axle center.

6. The vehicle air guide path structure according to claim 3 ,
wherein the partition member that partitions the vertically long air guide path into sections includes the flat portion extending along a front-rear direction of the vehicle body and the inclined portion that is lowered forward and downward toward an introduction port of an air guide path,
the vertically long air guide path is provided at the side surface portion of the vehicle body that is the rear side of the wheel house.

7. The vehicle air guide path structure according to claim 3 , wherein the vertically long inclined surface inclined outward in a vehicle width direction and a rear end portion of the flat portion of the partition member are exposed at an outlet port,
wherein the flat portion of the partition member protrudes to a rear side of the vehicle from the vertically long air guide path.

8. The vehicle air guide path structure according to claim 3 ,
wherein the vertically long inclined surface is formed at a predetermined angle to provide an airflow that passed through the vertically long air guide path flows in a rearward and outward direction.

9. The vehicle air guide path structure according to claim 3 ,
wherein a surface from the inclined portion to the flat portion is continuously formed on the partition member,
wherein the partition member that partitions the vertically long air guide path into sections includes the flat portion extending along a front-rear direction of the vehicle body and the inclined portion that is lowered forward and downward toward an introduction port of an air guide path.

10. The vehicle air guide path structure according to claim 2 ,
wherein a wheel house member that forms the wheel house includes:
a through hole formed in a portion overlapping an introduction port of the vertically long air guide path; and
a funnel portion erected along a peripheral edge of the through hole, and

wherein the funnel portion is provided in a state in which the funnel portion enters the introduction port.

11. The vehicle air guide path structure according to claim 2 , wherein the vertically long air guide path is formed from a lower side of an axle center of the wheel house to an upper side of the axle center.

12. The vehicle air guide path structure according to claim 1 ,
wherein the vertically long air guide path forming member includes:
an inner member located at an inner side of the vertically long air guide path in a vehicle width direction of the vehicle; and
an outer member located at an outer side of the vertically long air guide path in the vehicle width direction, and

wherein a facing inclined surface that follows the vertically long inclined surface is formed on a rear end edge portion of the outer member.

13. The vehicle air guide path structure according to claim 12 ,
wherein a wheel house member that forms the wheel house includes:
a through hole formed in a portion overlapping an introduction port of the vertically long air guide path; and
a funnel portion erected along a peripheral edge of the through hole, and

wherein the funnel portion is provided in a state in which the funnel portion enters the introduction port.

14. The vehicle air guide path structure according to claim 12 , wherein the vertically long air guide path is formed from a lower side of an axle center of the wheel house to an upper side of the axle center.

15. The vehicle air guide path structure according to claim 1 ,
wherein a wheel house member that forms the wheel house includes:
a through hole formed in a portion overlapping an introduction port of the vertically long air guide path; and
a funnel portion erected along a peripheral edge of the through hole, and

wherein the funnel portion is provided in a state in which the funnel portion enters the introduction port.

16. The vehicle air guide path structure according to claim 1 , wherein the vertically long air guide path is formed from a lower side of an axle center of the wheel house to an upper side of the axle center.

17. The vehicle comprising the vehicle air guide path structure according to claim 1 .

18. The vehicle air guide path structure according to claim 1 , wherein the vertically long air guide path is formed from a lower side of an axle center of the wheel house to an upper side of the axle center.
