Abstract
There is provided a double-skin structure in which it is possible to obtain an aesthetic improvement in addition to restricting an increase in the number of manufacturing steps. The structure includes a connection portion connecting together an end portion of a first projection portion of a first mold member and an end portion of a second projection portion of a second mold member; a cover plate that is provided between the first mold member and the second mold member, and that blocks an upper end side of a recessed portion bounded by a first rib, a second rib, the first projection portion, and the second projection portion; and a bonding portion that bonds the cover plate to the first mold member, and the cover plate to the second mold member.
Claims19
A double-skin structure comprising:
- a first mold member which includes
- a first upper plate including a first upper plate end portion,
- a first lower plate, part of which is disposed to face a lower surface of the first upper plate, and
- a first rib connecting together the first upper plate and the first lower plate, and
- in which the first lower plate includes a first projection portion projecting from a lower end of the first rib in an extension direction of the first lower plate;
- a second mold member which includes
- a second upper plate that includes a second upper plate end portion facing the first upper plate end portion in an extension direction of the first upper plate, and that extends in the extension direction of the first upper plate,
- a second lower plate, part of which is disposed to face a lower surface of the second upper plate, and which extends in the extension direction of the first lower plate, and
- a second rib connecting together the second upper plate and the second lower plate, and
- in which the second lower plate includes a second projection portion projecting from a lower end of the second rib in the extension direction of the first lower plate;
- a connection portion connecting together an end portion of the first projection portion and an end portion of the second projection portion;
- a cover portion that is provided in a recessed portion bounded by the first rib, the second rib, the first projection portion, and the second projection portion, and that blocks an upper end side of the recessed portion;
- and
- a bonding portion that bonds the cover portion to the first mold member, and the cover portion to the second mold member,
- wherein the cover portion includes
- a cover plate extending from the first upper plate to the second upper plate,
- a first side wall plate that is provided in a portion of the cover plate, which is positioned close to the first rib, and that extends from the cover plate to the first lower plate while a first gap is interposed between the first side wall plate and the first rib, and
- a second side wall plate that is provided in a portion of the cover plate, which is positioned close to the second rib, and that extends from the cover plate to the second lower plate while a second gap is interposed between the second side wall plate and the second rib,
- wherein the bonding portion is provided in each of the first gap and the second gap, and bonds the first rib to the first side wall plate and the second rib to the first side wall plate,
- wherein the cover portion includes a bottom plate that is disposed downward of the cover plate so as to face the cover plate, and that connects together a lower end of the first side wall plate and a lower end of the second side wall plate,
- wherein a lower surface of the bottom plate is disposed to face an upper surface of the first projection portion, an upper surface of the second projection portion, and an upper surface of the connection portion, and
- wherein the bonding portion is provided between the bottom plate and the first projection portion, the second projection portion, the connection portion.

A double-skin structure that forms part of a vehicle, and includes a door column and a side structure which are erectly disposed on a floor of the vehicle, the structure comprising:
- a bonding portion bonding together the door column and the side structure which are disposed to face each other in a longitudinal direction of the vehicle,
- wherein the door column includes
- a first side plate,
- a second side plate disposed inward from the first side plate, and facing the first side plate in a width direction of the vehicle,
- a first rib which extends in the width direction of the vehicle and connects together the first side plate and the second side plate, and from which a first projection portion of the first side plate projects to the side structure, and
- a second projection portion that projects to the side structure from a portion of the first rib, which is positioned opposite to one side of the first rib to which the second side plate is connected, and that forms an insertion groove which is interposed between the second projection portion and the first projection portion and into which an end portion of the side structure is inserted,
- wherein the side structure includes
- a third side plate extending to the insertion groove, and facing the first projection portion in the width direction of the vehicle,
- a fourth side plate extending to the insertion groove, and facing the second projection portion in the width direction of the vehicle, and
- a second rib connecting together the third side plate and the fourth side plate, and
- wherein the bonding portion is provided between the first projection portion and the third side plate, and between the fourth side plate and the second projection portion.
