Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for a molded article, and particularly to a mounting structure for a decorative synthetic resin molded article such as an exterior part for a vehicle.

2. Description of the Related Art Devices for attaching decorative synthetic resin molded products to car body panels, such as rear panels as exterior parts of automobiles, include devices that are designed to prevent the attached parts from being exposed to the outside and damaging the appearance. 1st
The figure is a perspective view showing the rear body of a car, and 1 is a rear panel attached to the car body panel;
It is molded from synthetic resin so that it has a shallow interior space, and its outer surface is decorated. 3 is a bumper.

FIG. 2 is a vertical sectional view showing the conventional mounting structure of the rear panel 2. The rear panel 2 includes a molded product main body 4, an adhesive flange 5 formed on the upper part, an engaging flange 6 formed on the lower part, and a locking protrusion. 7, and the adhesive flange 5 is adhered to the vehicle body panel 1 with an adhesive 8. The engaging flange 6 is held by a retainer 9 which is held by a retaining protrusion 7, and is inserted into the mounting hole of the vehicle body panel 1 through a sponge washer 11 by a bolt 10 welded to the retainer 9. It is attached to 12.

In the conventional mounting structure for a molded product configured as described above, the bolt 10 is welded to the retainer 9, the engagement flange 6 of the molded product is clamped and locked with the locking protrusion 7, and then the bolt 10 is welded to the retainer 9. Insert the sponge washer 11 into the mounting hole 12, and insert the bolt 10 into the mounting hole 12.
Insert and tighten with nuts from the back side of vehicle body panel 1.

However, such a conventional mounting structure has the following problems.

Since there are many parts, the cost is high and the number of assembly steps is large.

Since the holding portion of the retainer 9 requires spring performance, it is necessary to use stainless steel, which increases the material cost.

Since the mounting hole 12 is provided in the vehicle body panel 1, a sealing washer is required to prevent water from entering.

Since the mounting hole 12 is provided inside the edge of the vehicle body panel 1, floating of the molded product body 4 at the edge of the vehicle body panel 1 cannot be prevented.

This invention was made by focusing on such conventional problems, and includes providing a clip insertion hole and a clip locking portion on the rising side of a molded product, and forming a U-shape in the clip insertion hole. The purpose of this invention is to solve the above-mentioned problems by inserting and locking the insertion part of the clip, and sandwiching the end of the vehicle body panel between the folded part of the clip and the folded part of the clip.

The present invention provides a mounting structure for attaching a molded product to a part to be attached, which includes: a clip insertion hole provided on a rising side of the molded product; a clip locking portion formed at an end of the clip insertion hole; an insertion portion that is inserted into the clip insertion hole in a compressed state and is locked to the clip locking portion by spring back;
and a mounting clip having a folded part that clamps the end of the mounting part using elasticity between the insertion part and the mounting part.

The present invention will be explained below based on the drawings. FIG. 3 is a vertical sectional view showing a mounting structure for a molded product according to an embodiment of the present invention, FIGS. 4 to 6 are partially exploded perspective views, and FIG. 7 is a partially exploded perspective view. The same reference numerals as in FIG. 1 and FIG. 2 indicate the same or corresponding parts.

The molded product main body 4 is made of an injection molded product such as ASB resin, and a clip insertion hole 14 is provided on the rising side of the lower end between it and the clamping part 13.
The lower end of the molded product body 4 and the clamping part 13 are in communication with each other through a clip locking part 15 formed at the end of the clip insertion hole 14. Mounting clip 16 is U
It has a structure in which a metal plate such as an elastic steel plate formed in a shape of a letter doubles into a U-shape.
A plate-shaped insertion section 17 divided into two parts, this insertion section 17
It consists of a locking part 18 that protrudes outward from the tip of the inserting part 17, and a concentric folding part 20 that is folded back from the insertion part 17 via a bending part 19. The insertion portion 17 has elasticity in the width direction, and the insertion portion 17 and the folded portion 20 have elasticity in the thickness direction. Reference numeral 21 denotes a stud bolt whose head is embedded in the upper back surface of the molded product main body 4.

In the molded product mounting structure constructed as described above, the rear panel 2 is set on the vehicle body panel 1 using the stud bolts 21, the lower end of the molded product body 4 is aligned with the height of the lower end of the vehicle body panel 1, and the rear panel 2 is clamped. Part 13
is superimposed on the lower edge of the vehicle body panel 1,
The insertion portion 17 of the attachment clip 16 is inserted into the clip insertion hole 14 in a compressed state, and the folded portion 20 is slid between the insertion portion 17 and the clamping portion 13 and the lower edge of the vehicle body panel 1. Insertion part 17
When the clip is completely inserted into the clip insertion hole 14, the locking part 18 passes through the clip insertion hole 14, is pushed outward by the spring back, and is engaged with the clip locking part 15 and locked. .
The rear panel 2 is thus attached to the lower end of the vehicle body panel 1 by the attachment clips 16.

FIG. 8 is a cross-sectional view of a mold showing the state of molding the lower part of the rear panel 2, in which 22 is a cavity mold, 23 is a cavity mold;
24 is a core mold, 24 is a slide core mold, and 25 is a parting surface. The slide core mold 24 slides in the direction of arrow A to form a clip insertion hole 14 in the rising side of the lower end of the molded product body 4.

FIGS. 9 and 10 are perspective views of alternative embodiment mounting clips. The one in FIG. 9 is an example in which a metal rod such as a steel rod is used instead of the metal plate of the previous embodiment, and the surface of each rod is preferably coated with a nylon coat or the like to protect the paint film. The overall structure and mounting method are similar to the previous embodiment. The one in Figure 10 is polyacetal,
It is made of an elastic injection molded product of nylon, polypropylene, etc. In this case, a protective coating is not required. The structure is almost the same as the previous embodiment except that the insertion portion 17 is not divided.
The mounting method is also almost the same.

Note that the shape, structure, material, etc. of the mounting clip 16 can be changed in other ways.
The structure etc. can also be changed.

Furthermore, the object to be attached according to the present invention is not limited to the rear panel, but includes other resin molded products for automobiles and other molded products.

As explained above, according to this invention,
A clip insertion hole and a clip locking part are provided in the molded product, the insertion part of the mounting clip is inserted into the clip insertion hole, and the vehicle body panel is held between the clip insertion part and the folded part of the clip. You can get the following effect.

It is possible to eliminate the gap between the molded product and the vehicle body panel, which is the mounting part.

Sealing performance is improved because no holes are drilled into the vehicle body panel.

Since the number of parts is small, parts costs and assembly costs are reduced.

Since it can fit in a small space, there are no restrictions on modeling.

The mounting part is not visible from the surface, improving the appearance.

Even those with small upright sides can be installed.
