Abstract

A vehicle lower section structure includes: a suspension member, formed in a frame shape, including left and right side-rails extending in a vehicle front-rear direction, and front and rear cross members coupling the left and right side-rails together in a vehicle width direction; a contactless charger fastened to both a left side and a right side of a front portion and a rear portion of the suspension member, and being supported by the suspension member; and an electrical component disposed above the contactless charger and is electrically connected to the contactless charger, the electrical component is fastened to both the left side and the right side of the front portion and the rear portion of the suspension member and is supported by the suspension member.

Claims

1. A vehicle lower section structure comprising:

a suspension member, formed in a frame shape, including left and right side-rails extending in a vehicle front-rear direction, and front and rear cross members coupling the left and right side-rails together in a vehicle width direction;

a contactless charger fastened to both a left side and a right side of a front portion and a rear portion of the suspension member, and being supported by the suspension member; and

an electrical component disposed above the contactless charger and is electrically connected to the contactless charger, the electrical component is fastened to both the left side and the right side of the front portion and the rear portion of the suspension member and is supported by the suspension member.

2. The vehicle lower section structure of claim 1, wherein the contactless charger and the electrical component are co-fastened to the suspension member.

3. The vehicle lower section structure of claim 1, further comprising a suspension including a lower arm, wherein:

the lower arm includes an arm portion extending in the vehicle width direction and overlapping a vehicle axle in plan view, the arm portion being coupled to the suspension member;

the electrical component is fastened to a cross member disposed at a vehicle front-rear direction inner side; and

a coupling portion of the arm portion coupled to the suspension member, the cross member disposed at the vehicle front-rear direction inner side, and an end portion on the vehicle front-rear direction inner side of the electrical component, are arranged at positions aligned in the vehicle front-rear direction.

4. The vehicle lower section structure of claim 3, wherein:

the contactless charger is fastened to the cross member disposed at the vehicle front-rear direction inner side; and

the cross member disposed at the vehicle front-rear direction inner side, and an end portion on the vehicle front-rear direction inner side of the contactless charger, are arranged at positions aligned in the vehicle front-rear direction.

5. The vehicle lower section structure of claim 3, further comprising another electrical component disposed above the electrical component and is supported by the electrical component.
