Abstract

A solar battery mounting structure including a solar battery module which frame includes a light transmissive plate member, an adhesive portion by which a lower surface of a side end portion of the light transmissive plate member is adhered to an adhesive surface of a vehicle body frame member, and a fixation portion which is fixed to a lower surface of the light transmissive plate member through a sealing material layer, and is fixed to a fixation surface of the vehicle body frame member facing the lower surface, a protrusion portion in contact with the lower surface of the light transmissive plate member through the sealing material layer is fainted in the fixation portion, and frame a step portion is formed between the adhesive surface and the fixation surface.

First claim

What is claimed is:

1. A solar battery mounting structure comprising:
a vehicle body including a vehicle body frame member; and
a solar battery module including:
a light transmissive plate member which is arranged along the upper surface of the vehicle body;
an adhesive portion by which a lower surface of a side end portion of the light transmissive plate member is adhered to an adhesive surface of the vehicle body frame member;
a fixation portion which is fixed to a lower surface of the light transmissive plate member through a sealing material layer, and is fixed to a fixation surface of the vehicle body frame member facing the lower surface; and
a protrusion portion which is in contact with the lower surface of the light transmissive plate member through the sealing material layer is formed in the fixation portion;

wherein the solar battery module is disposed in an upper surface of the vehicle body;
wherein the solar battery module is fixed to the vehicle body frame member;
wherein a step portion is formed in the vehicle body frame member between the adhesive surface and the fixation surface; and
wherein the fixation surface is separated from the lower surface of the light transmissive plate member compared to the adhesive surface.

2. The solar battery mounting structure according to claim 1 ,
wherein the vehicle body frame member includes a body bracket protruding toward the fixation portion, and
the fixation surface is formed in the body bracket.

3. The solar battery mounting structure according to claim 1 ,
wherein the fixation portion includes a resin member in which a nut is embedded,
the fixation surface has a bolt hole opened therein, and
the fixation portion is fixed to the fixation surface by a bolt screwed into the nut through the bolt hole.

4. The solar battery mounting structure according to claims 1 ,
wherein a plurality of positioning pins for positioning the fixation portion at the time of manufacturing the solar battery module are disposed in the lower surface of the light transmissive plate member.

5. The solar battery mounting structure according to claims 1 , further comprising:
a back sheet which is disposed on a side of the sealing material layer opposite to the light transmissive plate member.
