Abstract

A vehicle panel structure that includes a first panel that is provided to a vehicle, the first panel being made from a fiber reinforced resin and including a plurality of first beads extending along one direction, and a second panel that is disposed so as to face the first panel and that includes a plurality of second beads extending along another direction intersecting with the first beads.

First claim

The invention claimed is:

1. A vehicle panel structure comprising:
a first panel that is provided to a vehicle, the first panel being made from a fiber reinforced resin and including a plurality of first beads extending along one direction;
a second panel that is disposed so as to face the first panel and that includes a plurality of second beads extending along another direction intersecting with the first beads; and
a core panel that faces the first panel and is disposed on an opposite side to the second panel, the core panel including a plurality of third beads that extend along the one direction and have the first beads superimposed thereon.

2. The vehicle panel structure of claim 1 , wherein:
each first bead has a sloping face that slopes in a vehicle front-rear direction from a top face of each first bead more gently than a sloping face of each third bead that slopes in the vehicle front-rear direction from a top face of each third bead.

3. The vehicle panel structure of claim 1 , wherein the first beads extend along a vehicle width direction.

4. The vehicle panel structure of claim 3 , wherein:
at a leading end portion of each first bead in the vehicle width direction, a width of each first bead widens on progression toward the leading end.

5. A vehicle panel structure comprising:
a battery case that is provided under a vehicle and houses a battery; and
a stack frame that is configured including a bottom wall configuring a bottom face of the battery case and an upper panel made from fiber reinforced resin and disposed facing the bottom wall, with the stack frame supporting the battery case, wherein
a plurality of first beads extending along one direction are provided to the upper panel,
a plurality of second beads extending along another direction intersecting with the first beads are provided to the bottom wall,
a core panel is provided below the upper panel, the core panel including a plurality of third beads extending along the one direction, and
the third beads and the first beads are disposed superimposed above and below each other.

6. The vehicle panel structure of claim 5 , wherein:
each first bead has a sloping face that slopes in a vehicle front-rear direction from a top face of each first bead more gently than a sloping face of each third bead that slopes in the vehicle front-rear direction from a top face of each third bead.
