Abstract

A vehicle underfloor structure has: a battery pack that is disposed beneath a floor of a vehicle, and that is a power source that drives a motor for traveling that is installed in the vehicle; and a fuel tank that is disposed beneath the floor of the vehicle, and between a vehicle body front side end portion and a vehicle body rear side end portion of the battery pack as seen in a side view, and between vehicle transverse direction both end portions of the battery pack as seen in a plan view.

First claim

What is claimed is:

1. A vehicle underfloor structure comprising:
a battery pack that is disposed beneath a floor of a vehicle and that is a power source that drives a motor for traveling installed in the vehicle; and
a fuel tank that is disposed beneath the floor of the vehicle, between a vehicle body front side end portion and a vehicle body rear side end portion of the battery pack as seen in a side view, and between vehicle transverse direction both end portions of the battery pack as seen in a plan view.

2. The vehicle underfloor structure of claim 1 , wherein a height of the fuel tank and a height of the battery pack are substantially the same.

3. The vehicle underfloor structure of claim 2 , wherein
the battery pack has a notch-shaped portion that opens in a vehicle body longitudinal direction, and
the fuel tank is disposed in the notch-shaped portion.

4. The vehicle underfloor structure of claim 2 , wherein
the battery pack has an opening portion that opens in a vehicle body vertical direction, and
the fuel tank is disposed in the opening portion.

5. The vehicle underfloor structure of claim 2 , wherein the fuel tank is fastened to the battery pack such that the fuel tank and the battery pack form a single unit.

6. The vehicle underfloor structure of claim 2 , wherein
an engine for generating electricity or for driving is installed in a front portion of the vehicle, and
concave portions, in which are disposed portions of an exhaust pipe that extends from the engine toward a vehicle body rear side, are formed in a lower portion of the battery pack and a lower portion of the fuel tank.

7. The vehicle underfloor structure of claim 1 , wherein
the battery pack has a notch-shaped portion that opens in a vehicle body longitudinal direction, and
the fuel tank is disposed in the notch-shaped portion.

8. The vehicle underfloor structure of claim 7 , wherein the fuel tank is fastened to the battery pack such that the fuel tank and the battery pack form a single unit.

9. The vehicle underfloor structure of claim 7 , wherein
an engine for generating electricity or for driving is installed in a front portion of the vehicle, and
concave portions, in which are disposed portions of an exhaust pipe that extends from the engine toward a vehicle body rear side, are formed in a lower portion of the battery pack and a lower portion of the fuel tank.

10. The vehicle underfloor structure of claim 1 , wherein
the battery pack has an opening portion that opens in a vehicle body vertical direction, and
the fuel tank is disposed in the opening portion.

11. The vehicle underfloor structure of claim 10 , wherein the fuel tank is fastened to the battery pack such that the fuel tank and the battery pack form a single unit.

12. The vehicle underfloor structure of claim 10 , wherein
an engine for generating electricity or for driving is installed in a front portion of the vehicle, and
concave portions, in which are disposed portions of an exhaust pipe that extends from the engine toward a vehicle body rear side, are formed in a lower portion of the battery pack and a lower portion of the fuel tank.

13. The vehicle underfloor structure of claim 1 , wherein the fuel tank is fastened to the battery pack such that the fuel tank and the battery pack form a single unit.

14. The vehicle underfloor structure of claim 1 , wherein
an engine for generating electricity or for driving is installed in a front portion of the vehicle, and
concave portions, in which are disposed portions of an exhaust pipe that extends from the engine toward a vehicle body rear side, are formed in a lower portion of the battery pack and a lower portion of the fuel tank.
