Abstract

A generator is provided at a front portion of an engine provided between a pair of front side frames at an offset position on one side, in a vehicle width direction, of a vehicle, and an electricity-storage device, a convertor, and a battery are provided on the other side, in the vehicle width side, of the vehicle. Accordingly, the electricity-storage device, the convertor, and the battery can be restrained from receiving any improper heat influence from the engine, and the length of harnesses coupling the generator, the electricity-storage device, the convertor, and the battery can be shortened as shorter as possible.

Claims

1. An electric component arrangement structure of a vehicle, comprising:

a right-and-left pair of front side frames extending in a vehicle longitudinal direction;

an engine provided between the pair of front side frames at an offset position on one side, in a vehicle width direction, of the vehicle;

a generator driven by the engine to generate electricity;

an electricity-storage device to store the electricity generated by the generator;

a convertor to convert the electricity from the electricity-storage device;

a battery, to which the electricity converted by the convertor is supplied; and

harnesses coupling the generator, the electricity-storage device, the convertor and the battery,

wherein said generator is provided at a front portion of said engine, and said electricity-storage device, said convertor, and said battery are provided on the other side, in the vehicle width side, of the vehicle.

2. The electric component arrangement structure of a vehicle of claim 1, wherein said electricity-storage device is provided on an outside, in the vehicle width direction, of one of said front side frames which is positioned on said other side, in the vehicle width side, of the vehicle.

3. The electric component arrangement structure of a vehicle of claim 1, wherein said electricity-storage device is provided in front of one of front wheels which is positioned on said other side, in the vehicle width side, of the vehicle, said convertor is provided in back of said one of the front wheels which is positioned on said other side, in the vehicle width side, of the vehicle, and a harness coupling said electricity-storage device and said convertor is arranged along a wheel arch which is formed above said one of the front wheels which is positioned on said other side, in the vehicle width side, of the vehicle.

4. The electric component arrangement structure of a vehicle of claim 2, wherein said electricity-storage device is provided in front of one of front wheels which is positioned on said other side, in the vehicle width side, of the vehicle, said convertor is provided in back of said one of the front wheels which is positioned on said other side, in the vehicle width side, of the vehicle, and a harness coupling said electricity-storage device and said convertor is arranged along a wheel arch which is formed above said one of the front wheels which is positioned on said other side, in the vehicle width side, of the vehicle.

5. The electric component arrangement structure of a vehicle of claim 1, wherein said convertor is provided between one of front seats which is positioned on said other side, in the vehicle width side, of the vehicle and a floor panel.

6. The electric component arrangement structure of a vehicle of claim 2, wherein said convertor is provided between one of front seats which is positioned on said other side, in the vehicle width side, of the vehicle and a floor panel.

7. The electric component arrangement structure of a vehicle of claim 3, wherein said convertor is provided between one of front seats which is positioned on said other side, in the vehicle width side, of the vehicle and a floor panel.

8. The electric component arrangement structure of a vehicle of claim 1, wherein crash cans are provided at respective front ends of said pair of front side frames, and said electricity-storage device is provided in back of one of said crash cans which is positioned on said other side, in the vehicle width side, of the vehicle.

9. The electric component arrangement structure of a vehicle of claim 2, wherein crash cans are provided at respective front ends of said pair of front side frames, and said electricity-storage device is provided in back of one of said crash cans which is positioned on said other side, in the vehicle width side, of the vehicle.

10. The electric component arrangement structure of a vehicle of claim 3, wherein crash cans are provided at respective front ends of said pair of front side frames, and said electricity-storage device is provided in back of one of said crash cans which is positioned on said other side, in the vehicle width side, of the vehicle.

11. The electric component arrangement structure of a vehicle of claim 1, further comprising a suspension cross member supporting both front wheels at both end portions thereof, wherein said suspension cross member includes a forward extension portion which extends forward below and substantially along one of said front side frames which is positioned on said other side, in the vehicle width direction, of the vehicle, and said electricity-storage device is located at the same position as a portion of said forward extension portion in the vehicle longitudinal direction, a lower end of which is located above a level of a lower end of the forward extension portion.

12. The electric component arrangement structure of a vehicle of claim 2, further comprising a suspension cross member supporting both front wheels at both end portions thereof, wherein said suspension cross member includes a forward extension portion which extends forward below and substantially along one of said front side frames which is positioned on said other side, in the vehicle width direction, of the vehicle, and said electricity-storage device is located at the same position as a portion of said forward extension portion in the vehicle longitudinal direction, a lower end of which is located above a level of a lower end of the forward extension portion.

13. The electric component arrangement structure of a vehicle of claim 3, further comprising a suspension cross member supporting both front wheels at both end portions thereof, wherein said suspension cross member includes a forward extension portion which extends forward below and substantially along one of said front side frames which is positioned on said other side, in the vehicle width direction, of the vehicle, and said electricity-storage device is located at the same position as a portion of said forward extension portion in the vehicle longitudinal direction, a lower end of which is located above a level of a lower end of the forward extension portion.

14. The electric component arrangement structure of a vehicle of claim 1, wherein said engine is provided laterally with an output shaft extending in the vehicle width direction, an air-intake duct is provided at a front portion of the engine, and said generator is provided beside said air-intake duct at the front portion of the engine.

15. The electric component arrangement structure of a vehicle of claim 1, wherein a transmission is provided on said other side, in the vehicle width direction, of the vehicle relative to said engine, and said battery is provided above said transmission.
