Abstract

A main battery and an auxiliary battery are both mounted on a hybrid vehicle without narrowing a cargo room.

A floor panel 102 includes a rising portion 102c that rises upward and extends in a widthwise direction of a vehicle 101, and a front portion 102a extending forward from the rising portion 102c. A rear seat 109 is mounted above the floor panel 102 in such a manner that a seat portion 109a is parallel to the front portion. The front portion 102a, the seat portion 109a of the rear seat 109, and the rising portion 102c form a housing space SP for mounting a main battery 110 and an auxiliary battery 111 side by side in the widthwise direction of the vehicle.

Claims

1. A hybrid vehicle comprising:

a floor panel including a rising portion that rises upward and extends in a widthwise direction of a vehicle, and a front portion that extends in a forward direction of the vehicle from the rising portion;

a fuel tank that is mounted below the floor panel, and that stores liquid fuel burned in an engine serving as a power source of the vehicle;

a rear seat provided above the floor panel with a seat portion that supports a hip of a passenger being opposite to the front portion;

a first mounting portion that is formed in a housing space enclosed by the front portion, the seat portion, and the rising portion, so as to mount a first battery which stores driving power of an electric motor serving as the power source of the vehicle; and

a second mounting portion that is formed in the housing space as being side by side with the first mounting portion in the widthwise direction of the vehicle so as to mount a second battery which assists a power supply by the first battery.

2. The hybrid vehicle according claim 1, further comprising:

rear wheel houses arranged at sides of the vehicle in the widthwise direction and at the rear of the rear seat,

wherein each of the side members has a first portion extending in the longitudinal direction of the vehicle along the inside of the rear wheel house in the widthwise direction of the vehicle, a second portion extending around from the first portion toward the outer direction of the vehicle along the shape of a front portion of the rear wheel house, and a third portion extending from the second portion toward the front part as making close to the outer direction of the vehicle.

3. The hybrid vehicle according to claim 1, further comprising:

a center cross member that is provided below the floor panel, and extends in the widthwise direction of the vehicle so as to support the first battery mounted in the first mounting portion through the floor panel.

4. The hybrid vehicle according to claim 1, further comprising:

a cover that is mounted in front of the first mounting portion and the second mounting portion for covering a front of the housing space.

5. The hybrid vehicle according to claim 4,

wherein a portion of the cover at a front of the second mounting portion can be opened and closed.

6. The hybrid vehicle according to claim 1,

wherein the side members project forward from a front surface of the rising portion.
