Abstract

A stiffened panel structure includes a panel-shaped component and a wire. The panel-shaped component has a panel body that curves in such a manner as to be convex outward. The wire has a first end portion and a second end portion. The first end portion is bonded to a first point on the inner surface of the panel body. The second end portion is bonded to a second point on the inner surface of the panel body. The wire is strained between the first point and the second point.

First claim

The invention claimed is:

1 . A stiffened panel structure comprising:
a panel-shaped component including a panel body that curves in such a manner as to be convex outward; and a wire having a first end portion and a second end portion, the first end portion being bonded to a first point on an inner surface of an area of the panel body excluding lateral edges of the panel-shaped component by an adhesive and the second end portion being bonded to a second point on the inner surface of the area of the panel body excluding the lateral edges by the adhesive in such a manner that the wire is strained between the first point and the second point, wherein: the panel body includes:
an expected load point onto which a load is expected to be applied from outside; and
a first area and a second area that, without the wire, are expected to be displaced in directions opposite to a loading direction and away from the expected load point when a load is applied to the expected load point from outside;
the second area is opposed to the first area with the expected load point in between; and the first point is in the first area, and the second point is in the second area.

2 . The stiffened panel structure according to claim 1 , wherein the panel-shaped component is made of metal.

3 . The stiffened panel structure according to claim 2 , wherein the panel-shaped component is made of steel.

4 . The stiffened panel structure according to claim 1 , wherein the wire is made of metal.

5 . The stiffened panel structure according to claim 4 , wherein the wire is made of steel.

6 . The stiffened panel structure according to claim 2 , wherein the panel-shaped component and the wire are made of a same kind of material.

7 . The stiffened panel structure according to claim 1 , wherein the wire is a CFRP wire.

8 . The stiffened panel structure according to claim 1 , wherein the panel-shaped component is an outer panel for an automobile.

9 . A stiffened panel structure comprising:
a panel-shaped component including a panel body that is flat or curves in such a manner as to be convex outward; an auxiliary component that is positioned inside the panel-shaped component and integrated with the panel-shaped component; and a wire having a first end portion and a second end portion, the first end portion being bonded to a first point on an inner surface of an area of the panel body excluding lateral edges of the panel-shaped component by an adhesive and the second end portion being bonded to the auxiliary component by the adhesive in such a manner that the wire is strained between the first point and the auxiliary component, wherein: the panel body includes:
an expected load point onto which a load is expected to be applied from outside; and
a first area that, without the wire, is expected to be displaced in a direction opposite to a loading direction and away from the expected load point when a load is applied to the expected load point from outside and
the first point is in the first area.

10 . The stiffened panel structure according to claim 9 , wherein the panel-shaped component is made of metal.

11 . The stiffened panel structure according to claim 9 , wherein the wire is made of metal.

12 . The stiffened panel structure according to claim 9 , wherein the panel-shaped component is an outer panel for an automobile.

13 . A stiffened panel structure comprising:
a panel-shaped component including a panel body that is flat or curves in such a manner as to be convex outward; a supporting member projecting from an inner surface of the panel body; and a wire having a first end portion and a second end portion, the first end portion being bonded to a first point on the inner surface of an area of the panel body excluding lateral edges of the panel-shaped component by an adhesive and the second end portion being bonded to a second point on the inner surface of the area of the panel body excluding the lateral edges by the adhesive, the second point being opposed to the first point with the supporting member in between, in such a manner that the wire is strained between the first point and the second point via the supporting member, wherein: the panel body includes:
an expected load point onto which a load is expected to be applied from outside; and
a first area and a second area that, without the wire, are expected to be displaced in directions opposite to a loading direction and away from the expected load point when a load is applied to the expected load point from outside;
the second area is opposed to the first area with the expected load point in between; the first point is in the first area, and the second point is in the second area; and the supporting member is positioned between the first area and the second area.

14 . The stiffened panel structure according to claim 13 , wherein the panel-shaped component is made of metal.

15 . The stiffened panel structure according to claim 13 , wherein the wire is made of metal.

16 . The stiffened panel structure according to claim 13 , wherein the panel-shaped component is an outer panel for an automobile.
