Abstract

A hybrid vehicle is provided in which a case (14) for housing an electrical component including at least a battery module is disposed underneath a floor of a luggage compartment interposed between left and right rear side frames (12) immediately to the rear of a fuel tank (42) disposed beneath a floor panel (41) of a hybrid vehicle, and a canister (48) is disposed on one of left and right sides of the case (14). Since the canister (48) is disposed further inside than the outer end of the rear side frame (12) in the left-and-right direction and further forward than the rear end of the case (14), when the vehicle is involved in a collision from the side the case (14) and the canister (48) can be protected by the rear side frame (12), and when the vehicle is involved in a collision from the rear the fuel tank (42) and the canister (48) can be protected by the case (14) while guaranteeing the capacity of a luggage compartment of a rear part of a vehicle body.

Claims

1. A hybrid vehicle in which a case for housing an electrical component including at least a battery module is disposed underneath a floor of a luggage compartment interposed between left and right rear side frames immediately to the rear of a fuel tank disposed beneath a floor panel, and a canister is disposed on one side of left and right sides of the case,

the canister being disposed further inside than the outer end of the rear side frame in the left-and-right direction and further forward than the rear end of the case.

2. The hybrid vehicle according to claim 1, comprising an air filter for filtering air that is to be introduced into the canister, the air filter being provided to the rear of the canister, and the air filter being disposed outside the rearward projection range of the canister.

3. The hybrid vehicle according to claim 2, wherein the rear end of the air filter is disposed further rearward than the rear end of the case.

4. The hybrid vehicle according to claim 1 or claim 2, comprising a silencer on the other side in the left-and-right direction of the case, the rear end of the silencer being disposed further rearward than the rear end of the case.

5. The hybrid vehicle according to claim 1 or claim 2, comprising a silencer to the rear of the case, the silencer being disposed within the rearward projection range of the case.

6. The hybrid vehicle according to claim 1 or claim 2, wherein the electrical component includes the battery module disposed in a lower part of the case and an inverter disposed in an upper part of the case, and an intermediate duct for guiding cooling air from the battery module to the inverter is disposed in a rear part of the case.

7. The hybrid vehicle according to claim 6, wherein the rear end of the canister is disposed further forward than the front end of the intermediate duct.

8. The hybrid vehicle according to claim 1 or claim 2, wherein the case is hangingly supported on the left and right rear side frames via a hanger frame, and the electrical component and the canister are disposed further forward than the rear end of the hanger frame.

9. The hybrid vehicle according to claim 1 or claim 2, comprising a reinforcing frame having opposite left and right ends connected to the left and right rear side frames, the reinforcing frame being disposed between the fuel tank and the case.

10. The hybrid vehicle according to claim 1 or claim 2, wherein an item-housing container is provided to the rear of the case.

11. The hybrid vehicle according to claim 1 or claim 2, wherein a spare tire is disposed above the case, a lower face of the spare tire being at a position equal to or higher than an upper face of the fuel tank, and the rear end of the spare tire being positioned further rearward than the rear end of the case.

12. The hybrid vehicle according to claim 11, wherein a bracket is provided on an upper face of the case, the bracket being separated therefrom by an impact, and the spare tire being supported by the bracket.

13. The hybrid vehicle according to claim 11, comprising a rear seat disposed above the fuel tank so as to sandwich the floor panel therebetween, an intake duct for introducing cooling air into the case, and an exhaust duct for discharging cooling air from the case, connecting parts of the intake duct and the exhaust duct connected to the case being disposed between a front part of the spare tire and a seat cushion of the rear seat.

14. The hybrid vehicle according to claim 13, wherein a cross member providing a connection between the left and right rear side frames is disposed between the seat cushion of the rear seat and the connecting parts of the intake duct and the exhaust duct connected to the case.

15. A hybrid vehicle in which a case for housing an electrical component including at least a battery module is disposed underneath a floor of a luggage compartment interposed between left and right rear side frames immediately to the rear of a fuel tank disposed beneath a floor panel, and a canister is disposed on one of left and right sides of the case,

wherein the canister is disposed further inside than the outer end of the rear side frame in the left-and-right direction and further forward than the rear end of the case, an air filter for filtering air that is to be introduced into the canister being disposed outside the rearward projection range of the canister,
