Description

[Detailed description of the invention] (Industrial application field) This invention is a retainer temporary fixing structure for automobile exterior parts,
Specifically, when attaching an automobile exterior product such as an automobile bumper or an air spoiler to the vehicle body, it is recommended that a retainer, which serves as a deformation prevention material for the automobile exterior product, be temporarily fixed in advance to facilitate the next process of attaching the vehicle body. The present invention relates to a retainer temporary fixing structure for automobile exterior parts.

(Prior art) Automotive exterior parts such as bumpers and air spoilers are mainly made of polyurethane elastic materials, and because they lack relative rigidity and are highly deformed due to heat shrinkage, they are attached to the car body with bolts. It is common to attach it via a retainer. For example, when an automobile bumper is attached to a backing member of a vehicle body, it is attached via a retainer with bolts, as disclosed in Japanese Utility Model Application Publication No. 53-26044. In this case, the retainer with bolts is temporarily fixed with bolts hooked into holes provided in the outer skin of the bumper in consideration of subsequent processes.

As another example, a method has been proposed in which the bolts of the retainer are inserted into the outer skin member and then fixed with clips.

(Problem that the invention aims to solve) However, if the retainer with bolts is simply inserted into the hole of the external member, slight vibrations may occur when the molded product is moved on a conveyor line, or if it is touched by a worker. The retainer could sometimes fall due to a slight movement of the retainer.

Further, in order to prevent this, a separate member such as a clip has been attached, but in this case, the installation requires many man-hours and has the drawback of increasing costs. Another major problem is that when inserting retainer bolts into the outer skin member, there are multiple holes for temporary fixing, so there is no standard for positioning the retainer, so positioning must be done manually. It was the current situation.

The present invention aims to improve these problems.First of all, it is possible to easily attach a retainer with bolts to a molded object, and the next attachment process can be carried out accurately without the retainer falling off easily. It is an object of the present invention to provide a structure for temporarily fixing a retainer of an automobile exterior product, which can be carried out and the retainer can be installed in a short time.

(Means for Solving the Problems) That is, the present invention is characterized in that the retainer is a plate-like body on which bolts are erected at predetermined intervals, while the automobile exterior parts are connected to other members. The mounting rib has a locking hole with a guide hole open at one end into which the bolt of the retainer is inserted, and at least one of the locking holes is connected to the other end. The shape of the reinforcing rib is different from that of the locking hole, and it is a reference hole for determining the mounting position of the retainer. The retainer is a retainer temporary structure for automobile exterior parts in which the bolt is inserted into the locking hole and the retainer is placed between the mounting rib and the reinforcing rib with the tip of the bolt protruding from the surface of the reinforcing rib. .

(Example) Next, an example of the present invention will be described with reference to the accompanying drawings.

Fig. 1 is a rear perspective view of the retainer temporary fixing structure portion of a bumper, which is an automobile exterior product of the present invention, and Fig. 2 is an A--
A sectional view, Fig. 3 is a BB sectional view of Fig. 2, Fig. 4
The figure is an enlarged plan view of the locking hole in Figure 1, and Figure 5 is an enlarged plan view of the locking hole in Figure 1.
An enlarged plan view of the reference hole shown in the figure, and FIG. 6 show the structure of the part where the above automobile exterior parts are attached to the car body. It is made of a molded product made of polymer, ABS resin, etc., and has a mounting rib 2 on its upper end for attaching the vehicle body or other parts, such as an air spoiler, and reinforcing ribs in its longitudinal and vertical directions. 3, 3 are provided, and these ribs are integrally molded with the bumper 1.

Locking holes 4 with one end open are arranged at predetermined intervals in the mounting rib 2, and a retainer having a shape different from that of the locking hole 4 is placed in the locking hole 4 at a predetermined position. A reference hole 5 is provided as a guide for positioning. The locking hole 4 and the reference hole 5 are elongated holes having a guide hole 6 open at one end, and are shaped so that retainers 8 to which bolts 7 are attached at predetermined intervals can be easily mounted. In addition, the shape of the reference hole 5 is particularly different from that of the locking hole 4, so that the installation position of the retainer 8 can be easily determined.

On the other hand, reinforcing ribs 3 are arranged below and parallel to the mounting ribs 2 as described above, but the spacing between them is not particularly limited, and the bolts 7 of the retainer 8 can be easily inserted. It's fine as long as it's possible. The reinforcing ribs 3 are integrally or separately molded with supporting members 9 having various shapes such as semicircular, elliptical, triangular, and quadrangular in cross section and protruding from the surface of the ribs 3 at predetermined intervals. , the distance a between the supporting member 9 and the reinforcing rib 3 is at least the height of the bolt 7 or less, and even if the retainer 8
The above-mentioned interval is not limited as long as it is held by the supporting member 9 even if it falls, and the bolt 7 attached to the retainer 8 protrudes from the surface of the mounting rib 2.

When inserting and installing the retainer 8 with bolts into the locking hole 4 and reference hole 5 provided in the mounting rib 2, slide the retainer 8 onto the support member 9 and insert the bolt 7 of the retainer 8 into the two holes 4 and 5. The retainer 8 is inserted through the opening of the bumper 1 and moved from the guide hole 6 to the end of the hole to prevent the retainer 8 from falling in the thickness direction of the bumper 1.

As shown in FIG. 6, the bumper 1 is equipped with the bolted retainer 8 temporarily fixed in the locking hole 4 and the reference hole 5 of the mounting rib 2. As shown in FIG. Reinforcement member 1
It is inserted into a through hole provided at 0 and fixed with a nut 11.

Incidentally, in the present invention, even when an air spoiler is attached to the bumper 1, the retainer 8 with bolts is temporarily fixed in the same manner as described above. In the embodiments described above, a structure in which a protruding support member 9 is provided upright on the surface of the reinforcing rib 3 and the retainer 8 is held on the support member 9 has been disclosed.

If the retainer 8 is held on the support member 9 in this manner, the fingers can fit between the retainer and the reinforcing ribs 3, and the retainer can be attached while being pinched with the fingers and moved freely. Therefore, there is an advantage unique to this embodiment that the bolt of the retainer can be easily attached to a locking hole that is curved in a hook shape like the locking hole of this embodiment.

(Effects of the invention) As described above, the retainer temporary fixing structure for automobile exterior parts of the present invention has locking holes with one end open into which retainer bolts are inserted at predetermined intervals in the mounting rib to which the vehicle body or other parts are attached. Since a reference hole having a shape different from the reference hole is provided, positioning of the retainer is extremely easy.

Furthermore, in the retainer temporary fixing structure for automobile exterior parts of the present invention, a reinforcing rib is provided on the underside of the mounting rib with a spacing smaller than the total height of the retainer relative to the mounting rib, so even if the retainer falls, The bolts of the retainer are received by the reinforcing ribs and protrude from the surface of the mounting ribs.
Therefore, even if the retainer comes off the locking hole due to vibrations from the conveyor or other equipment, the bolts can be tightened, resulting in extremely high assembly work efficiency.
