Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door structure for a vehicle in which a corner bracket is installed at a corner portion of a door sash.

[0002]

[Prior Art]

 Conventionally, as disclosed in, for example, Japanese Utility Model Laid-Open No. 63-134814, in a door structure of an automobile having a door body composed of an inner panel and an outer panel and a door sash projectingly provided on an upper end portion thereof, A guide rail is installed at the corner to guide the window glass up and down, and a corner bracket is installed between the guide rail and the door sash.

[0003]

[Problems to be solved by the device]

 The lower end of the above-mentioned corner bracket is fitted and joined in the opening formed in the upper side of the door body, and this joint is located inside the door body, and this portion must be spot welded. Therefore, in the above-mentioned conventional technique, a folding piece for joining is vertically projected at the upper end portions of the outer panel and the inner panel that form the door body, and the lower end portion of the corner bracket is welded to this folding piece. I have to. According to the above configuration, the outer panel and the inner panel of the door body have a special shape in which the shapes of the upper sides of the panels partially change, which complicates the manufacturing work and causes the folded piece to project upward. However, there is a problem that the joint with the corner bracket is exposed above the door body and the appearance deteriorates.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an automobile door structure capable of stably supporting a corner bracket with a simple structure.

[0005]

Means for Solving the Problems The present invention provides a vehicle door structure in which a corner bracket of a door sash is provided with a corner bracket including an outer member and an inner member, and a lower end portion of the outer member and the inner member. The flange portions facing each other are projected, and both flange portions are joined to the belt line reinforcement disposed inside the door body.

[0006]

[Action]

 According to the present invention having the above structure, the lower end of the corner bracket is fitted into the door body through the opening formed in the upper side of the door body, and the flange portion projecting from the lower end of the corner bracket is attached to the belt. It will be supported by being joined to the line force.

【Example】

 FIG. 1 shows an embodiment of a vehicle door structure according to the present invention. This automobile structure includes a door body 1 of a rear door that is attached to a rear portion of a side surface of a vehicle body, a door sash 2 that is erected on an upper side portion of the door body 1, a door sash 2 and an upper side of the door body 1. And a corner bracket 3 installed at a corner portion at the lower rear of the area defined by the section.

As shown in FIGS. 2 and 3, the door body 1 is composed of an outer panel 4 and an inner panel 5 each having a predetermined shape, and an inner side of an upper end portion thereof has a belt line reinforcement extending in the front-rear direction of the vehicle body. 6 are provided. The belt line reinforcement 6 is composed of a joint portion 7 joined to the outer panel 4 of the door body 1 and a substrate portion 8 standing upright on the upper side thereof, and the upper end portion of the substrate portion 8 is the door body described above. 1, which is disposed below an opening 9 for raising and lowering a door window formed on the upper side of the door window 1 to reinforce the belt line portion of the door body 1.

The corner bracket 3 is composed of an outer member 10 and an inner member 11 that are substantially triangular in shape and are installed to face each other. The outer member 10 and the inner member 11 have a rear edge portion having an L-shaped cross section. Shaped portions 12 and 13 are provided. The leading ends of the L-shaped portions 12 and 13 are polymerized and joined to each other to form a connecting portion 14 having a U-shaped cross section, and the connecting portion 14 is formed on the inner surface of the rear portion of the door sash 2. It is configured so that it can be fitted and mounted in the recess.

At the lower end of the outer member 10, a trapezoidal flange portion 15 that is introduced into the door body 1 from the opening 9 of the door body 1 is provided in a protruding manner. Further, at the lower end portion of the inner member 11, there is provided a flange composed of a projecting piece 16 extending outward at a position facing the flange portion 15 of the outer member 10 and a joining piece 17 extending downward from the tip portion thereof. The portion 18 is provided so as to project.

The flange portion 15 of the outer member 10 is brought into contact with the inner surface of the base plate portion 8 of the belt line reinforcement 6, and the flange portion 18 (joint piece 17) of the inner member 11 is attached to the outer member. While being in contact with the inner surface of the flange portion 15 of the member 10, they are integrally joined by means such as spot welding. An opening 20 is formed at the front end of the outer member 10 and the inner member 11 of the corner bracket 3 for installing a guide rail (not shown) that supports the window glass (not shown) so that the window glass can move up and down. There is.

As described above, the outer member 10 and the inner member 11 which form the corner bracket 3 installed in the corner portion of the door sash 2 are provided with flange portions 15 and 18 which are opposed to each other at the lower end portions thereof. Since 15 and 18 are joined to the belt line reinforcement 6 arranged in the door body 1, the lower end portion of the corner bracket 3 can be stably supported by the belt line reinforcement 6.

Further, by attaching the rear connecting portion 14 of the corner bracket 3 whose rigidity is ensured by supporting the lower end portion as described above to the inner surface of the rear portion of the door sash 2, the rear portion of the door sash 2 is attached to the corner portion. It can be reinforced by the bracket 3 and its rigidity can be effectively improved.

Further, since both the flange portions 15 and 16 are configured to be spot-welded to the belt line reinforcement 6 arranged in the door body 1, after the door is manufactured, the door is not manufactured. The outer panel 4 and the inner panel 5 of the main body 1 conceal the welded portion and prevent the exterior of the door from being deteriorated due to the exposed welded portion.

In the above embodiment, the structure of the present invention is applied to the rear door of the automobile, but the corner below the front part of the area defined by the door sash and the upper side of the door body. The configuration of the present invention can also be applied to the front door of a vehicle in which a corner bracket is installed.

[0016]

[Effect of the device]

 As described above, according to the present invention, the outer member and the inner member forming the corner bracket of the corner portion of the door sash are provided with the flange portions facing each other at the lower ends of the outer member and the inner member. Since it is joined to the belt line reinforcement installed inside the main body, the lower end of the corner bracket can be stably supported by the belt line reinforcement, and it is projected on the upper end of the door body. The rear portion of the door sash can be reinforced by the corner bracket, and its rigidity can be effectively improved.

Further, since the both flange portions are joined to the belt line reinforcement provided in the door body by means such as spot welding, the appearance of the door is deteriorated due to the joint portions being exposed to the outside. There is an advantage that it can be prevented.
