Title:
VEHICLE UNDER-FLOOR STRUCTURE
Document Type and Number:
Japanese Patent JP2021172226
Kind Code:
A
Abstract:
To provide a vehicle under-floor structure which can reduce the air resistance of a vehicle.SOLUTION: A vehicle under-floor structure 100 is provided under a floor of a vehicle 1 and includes an adjustment member 20 which adjusts a flow of the air. The adjustment member 20 returns the air to the front side by colliding with the air from the front side (see F2 in Fig.2(b)). With this, force, of heading to the rear side, of the air is reduced, therefore, the air does not directly flow to the rear side in the vicinity of a lower end part 20c of the adjustment member 20 and can turn around the lower end part (see F3 in the Fig.2(b)). Therefore, the adjustment member 20 can guide the air to the rear side and make the air head upward (see F4, F5 in the Fig.2(b)). In this case, a direction of the air flowing under the floor is adjusted by the adjustment member 20 to head upward on the rear side of the vehicle. Consequently, an eddy area on the rear side of the vehicle can be reduced and negative pressure of a vehicle rear surface 2 can be reduced.SELECTED DRAWING: Figure 2
