Abstract

A vehicle lower section structure includes, a suspension member; a contactless charging module attached to the suspension member and configured to receive power from a power supply module without contact; and an electrically conductive under-cover disposed adjacent to the contactless charging module in a vehicle front-rear direction at a vehicle lower side of the suspension member, and covering the suspension member from the vehicle lower side.

First claim

What is claimed is:

1. A vehicle lower section structure, comprising:
a suspension member;
a contactless charging module attached to the suspension member and configured to receive power from a power supply module without contact; and
an electrically conductive under-cover disposed adjacent to the contactless charging module in a vehicle front-rear direction at a vehicle lower side of the suspension member, and covering the suspension member from the vehicle lower side.

2. The vehicle lower section structure of claim 1 , wherein an end portion of the under-cover at a side of the contactless charging module is attached to the contactless charging module from the vehicle lower side.

3. The vehicle lower section structure of claim 1 , wherein an end portion of the contactless charging module at a side of the under-cover is attached to the under-cover from the vehicle lower side.

4. The vehicle lower section structure of claim 1 , wherein the contactless charging module comprises:
a contactless charging module body; and
a cover bracket that is provided at an end portion of the contactless charging module body at a side of the under-cover, and that is coupled to the under-cover.

5. The vehicle lower section structure of claim 2 , wherein the contactless charging module comprises:
a contactless charging module body; and
a cover bracket provided at an end portion of the contactless charging module body at a side of the under-cover,
wherein the end portion of the under-cover at the side of the contactless charging module is coupled to the cover bracket from the vehicle lower side.

6. The vehicle lower section structure of claim 5 , wherein a step is formed between a lower face of the cover bracket and a lower face of the end portion of the contactless charging module body at the side of the under-cover.

7. The vehicle lower section structure of claim 5 , wherein a lower face of the end portion of the under-cover, at the side of the contactless charging module, is disposed in the same plane as the lower face of the end portion of the contactless charging module body at the side of the under-cover.

8. The vehicle lower section structure of claim 5 , wherein the end portion of the under-cover, at the side of the contactless charging module, is attached to the cover bracket using a clip or a bolt.

9. The vehicle lower section structure of claim 8 , wherein:
the end portion of the under-cover at the side of the contactless charging module comprises an attachment recess that is recessed toward a vehicle upper side and that is superimposed on a lower face of the cover bracket; and
the clip comprises:
a clip body configured to be fitted into a through hole formed in the attachment recess and a through hole formed in the cover bracket; and
a flange provided at the clip body and including a lower face disposed in the same plane as the lower face of the end portion of the under-cover at the side of the contactless charging module, in a housed state of the flange within the attachment recess.

10. The vehicle lower section structure of claim 1 , wherein a lower face of the contactless charging module is configured as a flat planar face.

11. The vehicle lower section structure of claim 1 , wherein a lower face of the under-cover is configured as a flat planar face.

12. The vehicle lower section structure of claim 1 , wherein the contactless charging module comprises an electrically conductive power-receiving coil configured to receive power supply from a power supply module without contact.

13. The vehicle lower section structure of claim 1 , further comprising an electric motor disposed at a vehicle upper side of the suspension member, wherein the under-cover is disposed at the vehicle lower side of the electric motor.

14. The vehicle lower section structure of claim 1 , wherein an upper face of the under-cover is covered by an electrically conductive layer.

15. The vehicle lower section structure of claim 1 , wherein:
the contactless charging module is attached to a vehicle rear portion of the suspension member; and
the under-cover is attached to a vehicle front portion of the suspension member.
