Description

[Detailed description of the invention] (Industrial application field) This invention is a retainer temporary fixing structure for automobile exterior parts,
For more information, please refer to Automotive Bumper, Bumper Face,
When attaching an automobile exterior product such as an air spoiler to the vehicle body, for example, a reinforcing plate that serves as a thermal deformation prevention material for the automobile exterior product is temporarily fixed in advance to facilitate the next vehicle body attachment process. This 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 they are relatively lacking in rigidity and deform due to heat shrinkage, so they are not suitable for car bodies etc. It is generally attached via a retainer with bolts. 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 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 fall due to a slight movement in the retainer.

In particular, a shock-absorbing material mainly made of polyurethane foam is inserted inside the outer skin of a bumper, that is, the bumper face, which is formed by rim molding (RIM: Reaction, Injection, Molding), etc., and further shape-retaining material is used. In an automobile bumper that has a structure in which a backing member is attached to the back surface of the bumper face via a retainer in order to provide durability, it is necessary to push the back surface widely when inserting the shock absorber into the bumper face. However, the retainer often falls out or falls into the interior during bolt tightening, and the assembly process is laborious and time-consuming, and requires considerable skill.

In addition, separate members such as clips have been bonded to prevent this, but in this case, the installation process requires many man-hours and has the drawback of increasing costs. Furthermore, when inserting the retainer bolt into the outer skin member, there are multiple holes for temporary fixing, so there is no standard for positioning the retainer, and therefore the positioning must be done manually. It was the current situation.

The present invention aims to improve these problems.First of all, the retainer with bolts can be easily attached to the molded body, and the next attachment process can be carried out accurately without the retainer falling off easily. can be executed,
It is an object of the present invention to provide manufacturing of automobile exterior parts that allows positioning and installation of a retainer in a short time.

(Means for solving the problem) The features of the present invention for achieving the above purpose are as follows:
A locking hole having a guide hole with one end open for inserting a retainer bolt at a predetermined interval is provided in a mounting rib provided on an automobile exterior component, and
At least one reference hole is provided in the center to determine the mounting position of the retainer, which has a different shape from the above-mentioned locking hole, and a hook-shaped support member is attached to the back of the mounting rib to temporarily fix the retainer for an automobile exterior product. It's in the structure.

(Example) Hereinafter, specific examples of the present invention will be further described. Fig. 1 is the back side of the bumper face, which is an automotive exterior product of the present invention, Fig. 2 is a partially enlarged perspective view of the section A-A in Fig. 1, and Fig. 3 is the locking part shown in Fig. 1. Figure 4 is an enlarged plan view of the reference hole in Figure 1, and Figure 5 is a perspective view in direction B of Figure 1 with the reinforcing plate attached to the bumper in Figure 1. 6 is a partially enlarged view of a modified embodiment.

1 in FIG. 1 indicates the bumper face body.
Bumper face 1 is made of a molded product of polyurethane, foam, rubber, vinyl chloride, ethylene vinyl acetate copolymer, ABS resin, etc. It has a groove shape to insert a shock absorber inside, and a retainer is attached to the upper part of the back side. A long strip-shaped mounting rib 2 is provided.

The mounting rib 2 has locking holes 3 arranged at regular intervals in the longitudinal direction, and some of the locking holes 3 serve as a guide for positioning the retainer, which differs in shape from the locking hole 3. One reference hole 4 is provided in the center, and an L-shaped hook-shaped support member 5 is provided integrally with the mounting rib 2 on the back surface. The locking hole 3 and the reference hole 4 are elongated holes each having an open end at one end and a guide hole 6 having an L-shaped planar shape. The reference hole 4 has a size and shape that can be moved in the longitudinal direction, and the reference hole 4 has a size and shape that can generally restrict the movement of the bolt 8 of the retainer in the longitudinal direction and the height direction of the mounting rib 2 so that the retainer 7 can be positioned. It is desirable to do so. The distance between the L-shaped hook-shaped support member 5 and the mounting rib 2 is at least equal to or less than the height of the bolt 8,
Even if the tips of the bolts 8 of the retainer 7 are held down, the bottom surface of the retainer 7 is held by the support member 5, and if the bolts 8 attached to the retainer 7 protrude from the surface of the mounting rib, the above-mentioned interval is It is not limited.

When the retainer 7 with bolts is inserted into the locking hole 3 and the reference hole 4 provided in the mounting rib 2, the bolt 8 provided in the retainer 7 is inserted into the corresponding guide hole of the locking hole 3 and the reference hole 4. 6 along the guide hole 6, and insert the retainer 7 between the mounting rib 2 and the support member 5.
Furthermore, the bolts 8 provided on the retainer 7 are moved to the respective locking holes 3 and reference holes 4. By doing so, the retainer 7 is prevented from falling downward in FIG.
This is prevented by the wall surface of the bolt 8 coming into contact with the bolt 8.

Furthermore, the retainer 7 is prevented from falling into the bumper face 1, that is, from escaping to the left in FIG. 5, because the bottom of the retainer 7 hits the support member 5.

As shown in FIG. 5, the bumper face 1 is equipped with the bolted retainer 7 that is locked in the locking hole 3 and the reference hole 4 of the mounting rib 2, and a shock absorbing member 9 is inserted inside the bumper face 1, as shown in FIG. After that, insert the retainer 7 and the bolt 8 into the through hole 1 provided in the reinforcing plate 10.
1 and fixed with a nut 12. The shapes of the locking hole 3, the reference hole 4, and the guide hole 6 are not limited to the above example, and the locking hole is a locking hole 3' having a straight guide hole 6' as shown in FIG. A structure has also been considered in which the lower part of the rib 2' is L-shaped to prevent it from falling to the lower part.

(Effects) In this way, 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 bonded. Moreover, a reference hole with a different shape is provided in the center,
This makes it extremely easy to position the retainer, and furthermore, a support member is provided on the back side of the mounting rib with a gap that allows the retainer to be easily inserted, so it can be used when assembling automotive exterior parts, or Even if strong vibrations or shocks are applied during assembly to a car, or the bolts of the retainer are held down by nuts, the support member holds the bottom of the retainer and prevents the retainer from slipping out of the locking hole. In addition, since the bolts of the retainer have a distance from the mounting rib support member such that they protrude from the surface of the mounting rib, the retainer can be securely locked and the next step can be carried out.
