Abstract

To provide a panel whose surface rigidity can be improved appropriately in accordance with a load. Provided is a panel including: a load point to which a load is applied from the outside; and a protrusion that protrudes from a surface of the panel and is formed continuously or discontinuously around the load point. The protrusion intersects, at a plurality of positions, each of a plurality of virtual straight lines extending radially from the load point.

First claim

1 . A panel comprising:
a load point to which a load is applied from the outside; and a protrusion that protrudes from a surface of the panel and is formed continuously or discontinuously around the load point, wherein the protrusion intersects, at a plurality of positions, each of a plurality of virtual straight lines extending radially from the load point.

2 . The panel according to claim 1 ,
wherein the load point is a junction with another member.

3 . The panel according to claim 1 , comprising a plurality of the load points,
wherein at least one of density, a formation range, and a cross-sectional shape of the protrusion differs in accordance with an assumed load applied to the load point.

4 . The panel according to claim 3 ,
wherein, at a boundary portion where the protrusions formed around the corresponding plurality of load points intersect each other, side faces of the protrusions are continuous via a curved surface.

5 . The panel according to claim 1 ,
wherein a ridge line of the protrusion perpendicularly intersects the plurality of virtual straight lines.

6 . The panel according to claim 1 ,
wherein the plurality of virtual straight lines are straight lines connecting the load point and a plurality of vertices of the panel.

7 . The panel according to claim 1 ,
wherein the protrusion includes a top face parallel to the surface of the panel.

8 . The panel according to claim 1 ,
wherein the protrusion includes a plurality of ring-shaped protrusions formed concentrically, and wherein the center of the ring-shaped protrusion coincides with the load point.

9 . The panel according to claim 1 ,
wherein the protrusion includes a spiral-shaped protrusion whose base point is the load point.

10 . The panel according to claim 1 ,
wherein the panel is made of a steel sheet.

11 . The panel according to claim 1 ,
wherein the panel is a floor panel of an automobile.
