Description

  The present invention relates to a vehicle door that supports an exterior member disposed along a lower frame portion (side sill) of an entrance / exit.

Some vehicle doors are provided with an exterior member extending to a lower frame portion (side sill) of the entrance / exit.
The exterior member (exterior part) of this door is formed with an inner part through a folded part (thin hinge part) in the lower flange part of the outer part, and the folded part (thin hinge part) is folded into an inner part at the outer part. Are joined to form a closed cross section (see, for example, Patent Document 1).

However, in the prior art (Patent Document 1), in the case of an automobile having a large entrance, the space (gap) between the side sill and the lower part of the door body is larger than the lower part of the door. .
In order to reduce the interval, it is conceivable to arrange the inner part through the folding part (thin hinge part) so that the inner plate of the door body extends downward, but the inner part becomes larger and the weight is increased. To increase.
In addition, when providing a seal member that seals the gap between the door and the vehicle body, it is desirable to provide a seal member on the steel plate used for the door (peripheral edge of the door body). Since it becomes impossible, it cannot provide in a steel plate. As a countermeasure, if a seal member is provided on the inner side of the exterior member facing the side sill, the strength of the inner side becomes a concern with respect to a load such as a force for compressing the seal member.
That is, it has been desired to eliminate the gap with the door opening frame (side sill), increase the strength, and ensure a large door opening (entrance / exit).

Yes.

  As shown in FIGS. 11 to 13, the inner wall 188 is opened on the wall 68 of the closed cross-section 166, the seal backup portion 66, the joining flange 124, and the wall 141, and the clip 141 is inserted. The first seal fixing clip hole 234 and the connecting rib 129 are provided.

  The bent portion 186 is thinner than the non-design portion 184 and the inner wall 188.

As shown in FIG. 13, the connection rib 129 has a length Lr that gradually decreases as the width of the non-design portion 184 gradually decreases.
The height Hr (FIG. 13) of the connection rib 129 is lower than the height of the lower outer surface seal portion 64 and is about 60%. As a result, the lower outer surface seal portion 64 can be pressed and held without impairing weight reduction.

Next, the operation of the vehicle door 12 according to the embodiment will be described.
In the door 12 for the vehicle 11, as shown in FIG. 6, even when the size of the door body 15 is limited, the door 12 is made larger than the door body 15 by the distance α by the exterior member (outer decoration member) 27. It is possible to eliminate the gap with the door opening frame portion 32 forming the door opening portion 161.

  Further, in the vehicle 11 door (front left door) 12, when a load (impact) is input to the door 12 (for example, in the case of a side collision), the exterior member (outside decoration member) 27 that does not overlap the door body 15 is closed. Since the load is transmitted to the cross section 166, the load can be distributed to the closed cross section 166, and the strength of the extension 164 that cannot be directly held by the door body 15 can be increased.

Although the vehicle door of the present invention is a side door such as the front door 12 in the embodiment, it may be a tailgate or a roof door other than the side door.
The exterior member (outer decoration member) is attached to the outside of the lower portion 25 of the door body 15, but is not limited to the lower portion 25. An exterior member (outer decoration member) may be attached to the front end, rear end, upper end, or the like.

Moreover, the material of the exterior member (outside decoration member) is arbitrary.
The embodiment is an example and is not limited to the embodiment.

  The vehicle door of the present invention is suitable for an automobile.
