Abstract

A vehicle battery mounting structure has: a battery frame lower member that is made of resin, and that is disposed at vehicle transverse direction inner sides of energy absorbing members provided at a lower side of a floor panel, and that, together with a battery frame upper member, structures a battery frame that supports a battery; a lower ductile member having a lower main body portion that is joined to vehicle transverse direction outer side end portions of the battery frame lower member, and lower flange portions that are fixed to a bottom surface side of the floor panel; and inclined walls that are formed at vehicle transverse direction outer side end portions of the battery frame lower member, and that are inclined from vehicle transverse direction outer upper sides toward vehicle transverse direction inner lower sides.

First claim

The invention claimed is:

1. A vehicle battery mounting structure, comprising:
a battery frame lower member, the battery frame lower member being made of resin, the battery frame lower member being disposed at vehicle transverse direction inner sides of energy absorbing members provided at a lower side of a floor panel, and the battery frame lower member, together with a battery frame upper member, structuring a battery frame, and the battery frame member supporting a battery;
a lower ductile member having:
a lower main body portion, the lower main body portion being joined to vehicle transverse direction outer side end portions of the battery frame lower member, and
lower flange portions, the lower flange portions being fixed to a bottom surface side of the floor panel; and

inclined walls, the inclined walls being formed at the vehicle transverse direction outer side end portions of the battery frame lower member, and the inclined walls being obliquely inclined relative to a bottom plate of the battery frame lower member toward the lower ductile member.

2. The vehicle battery mounting structure of claim 1 , wherein portions of the lower main body portion are made to be standing portions, the standing portions gradually separate from the inclined walls, and regions between the inclined walls and the standing portions are filled-in and joined by an adhesive.

3. The vehicle battery mounting structure of claim 2 , wherein plate members are provided at the standing portions, the plate members each projecting-out from an end of the standing portions toward the battery frame lower member.

4. The vehicle battery mounting structure of claim 1 , wherein vertical walls that extend upward are formed at vehicle transverse direction outer side end portions of the inclined walls.

5. The vehicle battery mounting structure of claim 1 , further comprising an upper ductile member having an upper main body portion and upper flange portions, the upper main body portion being joined to vehicle transverse direction outer side end portions of the battery frame upper member, and the upper flange portions, together with the lower flange portions, being fixed to the bottom surface side of the floor panel,
wherein inclined portions are formed at the upper main body portion sides of the upper flange portions, and the inclined portions are obliquely inclined relative to the bottom plate of the battery frame lower member toward the lower ductile member.
