In the hybrid vehicle according to the present embodiment, as shown in
In a conventional hybrid vehicle, the fuel tank 200 is mounted in the area in which the battery 100 is mounted in the exemplary embodiment, and the battery 100 is mounted in an area defined under a trunk compartment. As a result, the area in the trunk compartment is decreased, whereby marketability with regard to the trunk compartment is reduced, and it is difficult to distribute weight in the trunk compartment.
In the present embodiment, the battery 100 is mounted in the area defined under the body floor 2, on which the double seat 1 is disposed, and the fuel tank 200 is disposed at the upper end portion of the rear-wheel suspension 3 and the rear of the body cross member 4, i.e. between the rear-wheel suspension 3 and a thermal damage prevention muffler 5, improving marketability with regard to the trunk compartment and the distribution of weight in the trunk compartment.
As shown in
The fuel tank band 6 surrounds the external surface of the fuel tank 200 together with the rear-wheel suspension 3 and is fastened to the body to support the fuel tank 200. The fuel tank band 6 includes a steel plate having a predetermined thickness, by which the rigidity of the fuel tank band 6 is increased. In addition, to the present end, ribs may be formed on the fuel tank band 6.
The fuel tank band 6 may extend in the longitudinal direction of the fuel tank 200 to support the fuel tank 200. Alternatively, as shown in
Although not shown, the seating area A is recessed upward from a base surface 7 of the body wherein the top portion surface of the seating area A defines the bottom surface of the trunk compartment, accordingly a trunk board disposed in the trunk compartment extends.
In addition, the rear end portion of the seating area A, the upper part of which is recessed, may be formed to be lower than the base surface 7 of the body wherein spare tools and tires may be loaded in the trunk compartment.
As shown in
In detail, a forward-protruding fastening part 210 of the fuel tank 200 is positioned at a fastening bracket formed at the body cross member 4 in the state in which the fuel tank 200 is disposed in the seating area A, and then the fuel tank 200 may be fixed to the body cross member 4 using a fastening member.
