DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bracket structure in a belt molding, particularly for a rear side door of a vehicle such as a passenger car.

[0002]

2. Description of the Related Art In this type of vehicle, for example, as shown in FIG. 5, a belt molding 3 is laid along an upper edge of a door body 2 of a rear door 1. The belt molding 3 is composed of a main body 4 and a garnish 5 continuously provided at a rear end of the main body 4. FIG. 6 shows an example of a conventional bracket structure in the belt molding 3. In the drawing, reference numeral 6 denotes an assembling bracket for assembling the main body portion 4 and the garnish portion 5 with each other, and reference numeral 7 denotes an attachment collar (or bracket) for attaching the garnish portion 5 to the door panel 8 of the door body 2.

As shown in FIG. 7, one end of the assembling bracket 6 is fastened to the main body 4 by bolts 9 and the other end thereof is joined to the garnish part 5 by welding 10 (marked by “x”). You. As shown in FIG. 8, one end of the mounting collar (or bracket) 7 is fastened to the door panel 8 by bolts 11 and the other end is joined to the garnish part 5 by welding 12 (x mark). .

[0004]

The conventional belt molding 3
In the bracket structure described above, the structure in which two parts, the mounting bracket 6 and the mounting collar 7, are provided as described above is general. However, with such a separate structure, the mounting bracket 6 and the mounting collar 7 are not provided.
It is necessary to arrange the respective parts at predetermined positions, and to perform special welding or the like. At this time, particularly in the mounting collar 7, as shown in FIG. 8, the joining surface 7a with the garnish portion 5 where the welding 12 is to be performed is formed as a slope, so that not only welding becomes difficult, but also Even in this case, it is necessary to ensure the flatness of the joint surface 7a.

As described above, in the conventional bracket structure, 2
Due to the component configuration, the number of components, the arrangement position or space, the number of welding steps thereof, and the like are restricted. As a result, the design of the product must be limited.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a bracket structure for an automobile belt molding that can save space and expand the degree of freedom of the welding position of the bracket.

[0007]

In the bracket structure of the present invention, the upper edge portion of the door body is provided.
A long body laid along and the length of this body
Garniture that is separate from the body that is located at the end in the
A belt molding constituted by Gerhard unit, the Gani'
To the main body while being joined to the
To the door body on the mounting bracket and the other side.
And an integrated bracket in which a mounting bracket portion to be connected is integrally formed .

[0008]

According to the present invention, the integral bracket makes it possible to have both the function of assembling the main body and the garnish part and the function of attaching the garnish part to the door panel. Therefore, the number of parts can be reduced, and the space for the arrangement can be saved. By using a single bracket in this way, the degree of freedom of the welding position can be increased, and the design of the product can be further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a bracket structure for an automobile belt molding according to the present invention will be described below with reference to FIGS.
Also in the present embodiment , as shown in FIG. 5, the long main body 4 and the main body 4 are laid along the upper edge of the door main body 2.
Having a configured belt molding 3 by gas <br/> Nisshu part 5 separate from the main body portion 4 which is arranged at a longitudinal end of 4
You.

As shown in FIG. 1, the integrated bracket 20 according to the present invention comprises an assembling bracket portion 21 for assembling the main body portion 4 and the garnish portion 5 with each other, and a garnish portion 5 of the door main body 2. And a mounting bracket 22 for mounting to the door panel 8. The sectional shape is, for example, a convex shape (or, for example, a substantially hat shape) as shown in the illustrated example.

The integral bracket 20 is joined to the garnish part 5 by welding 24 at a connecting part 23 between the mounting bracket part 21 and the mounting bracket part 22 on both sides. Bolt holes 21a, 22a are formed in the mounting bracket portion 21 and the mounting bracket portion 22,
As shown in FIG. 2, the mounting bracket 22 is attached to the door panel 8 by the bolt 25 inserted into the bolt hole 22 a.
Is concluded. In addition, a bolt (not shown) is inserted through the bolt hole 21a, and the main body 4 and the garnish 5 are inserted.
Are mutually fastened and assembled.

According to the bracket structure of the first embodiment, in a single integral bracket 20, the main body 4 and the garnish 5 are mutually assembled by the assembling bracket 21, and the mounting bracket 22 is mounted. Thereby, the garnish part 5 is attached to the door panel 8. As a result, the number of parts can be reduced, the number of welding steps can be reduced, and the cost can be reduced. Further, space saving for disposing the integral bracket 20 can be achieved. Therefore, the degree of freedom of the welding position (weld 24) of the connecting portion 23 is increased, so that the design of the product can be improved. In addition, since assembly and attachment can be performed only by the integral bracket 20, the precision of parts and the precision of the vehicle can be improved.

FIG. 3 and FIG. 4 show a second embodiment of the bracket structure in the automobile belt molding according to the present invention. As shown in FIG. 3, the integrated bracket 30 according to the second embodiment includes an assembling bracket portion 31 for assembling the main body portion 4 and the garnish portion 5 with each other, and the garnish portion 5 of the door main body 2. A mounting bracket portion 32 for mounting to the door panel 8; and a connecting portion 33 for connecting the mounting bracket portion 31 and the mounting bracket portion 32.
And The integral bracket 30 is joined to the garnish part 5 by welding 34 at the connecting part 33. In this second embodiment, the integrated bracket 30
Has a concave shape (or substantially a C-shape), for example, as shown in the figure.

According to the bracket structure of the second embodiment, it is possible to reduce the number of parts and the number of welding steps as in the case of the first embodiment, thereby realizing cost reduction. In addition, the precision of parts and the precision of the vehicle can be improved. And especially the connecting part 3
By providing 3, it is possible to suppress so-called sink marks of the injection molded portion 5a. Incidentally, in the case of the first embodiment, for this purpose, it is necessary to provide a predetermined spacer S (see FIGS. 1 and 2) between the mounting bracket 21 or the mounting bracket 22 and the garnish 5. is there.

[0015]

As described above, according to the present invention, by providing the integral bracket, the number of parts can be reduced and space can be saved, and the degree of freedom of the welding position can be increased.
It has advantages such as improvement of product design and cost reduction.
