Abstract

A vehicle floor lower structure comprising a fuel tank that is disposed under a floor of a vehicle, and a battery pack that is disposed under the floor of the vehicle and at a vehicle body rear side of the fuel tank, and the battery pack is configured to be a power source to drive a traction motor installed in the vehicle.

Claims

1. A vehicle floor lower structure comprising:

a fuel tank under a floor of a vehicle;

a battery pack under the floor of the vehicle and at a vehicle body rear side of the fuel tank, and that is configured to be a power source to drive a traction motor installed in the vehicle, a front surface of the battery pack directly facing a rear surface of the fuel tank;

a fuel supply port for supplying fuel to the fuel tank at a vehicle body upper rear side of the battery pack; and

an inlet pipe that links the fuel tank and the fuel supply port at a vehicle body upper side of the battery pack, and that is overlapped with respect to the battery pack when viewed from above the vehicle in a vehicle up-down direction.

2. The vehicle floor lower structure of claim 1, wherein an upper recessed section is at an upper face of the battery pack, the upper recessed section including a portion of the inlet pipe.

3. The vehicle floor lower structure of claim 2, further comprising:

an exhaust pipe, wherein

a lower recessed section is at a lower face of the battery pack, and a portion of the exhaust pipe, that extends from an engine toward a vehicle body rear side, is in the lower recessed section, and

the upper recessed section and the lower recessed section are separated by a distance from each other in the vehicle plan view.

4. The vehicle floor lower structure of claim 3, further comprising:

a thermal insulation member between the battery pack and the exhaust pipe.

5. The vehicle floor lower structure of claim 3, wherein fuel tank includes a recessed portion on a bottom face of the fuel tank and an outlet of the recessed portion of the fuel tank is aligned with an inlet of the lower recessed section of the battery pack.

6. The vehicle floor lower structure of claim 1, further comprising:

an exhaust pipe that extends from an engine toward a vehicle body rear side is routed at a vehicle body lower side of the battery pack.

7. The vehicle floor lower structure of claim 6, wherein a lower recessed section is at a lower face of the battery pack, the lower recessed section including a portion of the exhaust pipe.

8. The vehicle floor lower structure of claim 6, further comprising:

a thermal insulation member between the battery pack and the exhaust pipe.
