Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a mounting structure for synthetic resin molded products for vehicles such as moldings and door cover corners.

[Conventional technology]

Fig. 9 is a perspective view of a conventional mounting clip shown in, for example, JP-A-60-183243, Fig. 10 is a perspective view of a synthetic resin molded product, Fig. 11 is a sectional view showing the state during installation, and Fig. FIG. 12 is a sectional view showing the state after installation.

In the figure, reference numeral 1 denotes a mounting clip, which consists of a mounting base 2 and a clip 3. 4 is a synthetic resin molded product,
It has a recess 5 with a protruding edge on the back surface. Mounting stand 2
A clip part 7 that engages with the clip 3 is attached to a spin weld part 6 that is spin welded to the recess 5 of the molded product 4;
and a protrusion 8 are provided. The clip 3 is adapted to elastically engage with a mounting hole 10 in a vehicle body panel 9 to which it is mounted.

In the above configuration, the spin welding part 6 of the mounting base 2
is engaged with the recess 5 of the molded product 4, and when the protrusion 8 is hooked onto a jig and pressed while rotating, one or both of the resins melts due to frictional heat, and the spin welding part 6 is welded to the molded product 4. At the same time, the protrusion 8 softens and separates. Thereafter, as shown in FIG. 11, the clip 3 is engaged with the clip portion 7. and the twelfth
As shown in the figure, the molded product 4 is attached to the vehicle body panel 9 by inserting and engaging the clip 3 into the mounting hole 10 of the vehicle body panel 9. In the attached state, the molded product 4 is stabilized by the opposing effects of the pressing force O of the molded product 4 and the pressing force P of the clip 3.

[Problem that the invention attempts to solve]

However, in such a conventional mounting structure, it is necessary to spin-weld the mounting base 2 so that the distance l from the back surface of the molded product 4 to the vehicle body panel 9 is constant, but spin welding allows for some variation. Therefore, it is difficult to keep the distance l constant. Therefore, if the distance 1 is small, the clip 3 or the molded product 4 may be deformed or cannot be attached, and if the distance 1 is large, the clip 3 or the molded product 4 may become unsteady.

This idea was developed to solve the above problems.The synthetic resin molded product for vehicles can be easily and stably installed by keeping the distance between the synthetic resin molded product and the object to which it is attached constant. The purpose is to obtain a mounting structure for.

[Means for solving the problem]

This idea includes a mounting base that has a spin welded part and a threaded part that are spin welded to a synthetic resin molded product,
A vehicle comprising: a clip having a threaded portion that is screwed into the threaded portion; and a clip portion that engages with a mounting hole of an object to which the clip is attached; and a locking portion that is provided between the mounting base and the clip to prevent rotation. This is a mounting structure for synthetic resin molded products.

[Effect]

In the mounting structure for synthetic resin molded products for vehicles of this invention, the spin welding part of the mounting base is spin welded to a predetermined position on the synthetic resin molded product, and the threaded part of the clip is screwed into the threaded part of the mounting base to a predetermined depth. to prevent the clip from rotating by engaging the locking part. Then, the synthetic resin molded product is attached to the object by engaging the clip portion of the clip with the mounting hole of the object to be attached.

By adjusting the screwing depth of the threaded part,
Since the clip can be attached at any height and the locking portion prevents rotation in this state, the distance between the synthetic resin molded product and the object to be attached can be kept constant. Therefore, the synthetic resin molded article can be stably attached to the object to be attached due to the opposing effects of the pressing force of the molded article and the pressing force of the clip.

〔Example〕

This invention will be explained below with reference to embodiments of the drawings. Fig. 1 is a sectional view of the mounting clip of the embodiment, Fig. 2 is a plan view of the mounting base, Figs. 3 and 4 are sectional views corresponding to A-A in Fig. 1 showing the state during installation, and Fig. 5 The figure is a sectional view corresponding to A-A showing the state after installation, and the same reference numerals as in FIGS. 9 to 12 indicate the same or corresponding parts.

The mounting clip 1 consists of a mounting base 2 and a clip 3. The mounting base 2 is spin-welded to a synthetic resin molded product 4, and the clip 3 is attached to a vehicle body panel 9 to which it is attached.
mounted on. Clip 1 is made of elastic thermoplastic resin such as polyacetal resin or polyamide resin, and molded product 4 is made of ABS resin or PVC.
Molded from thermoplastic resin such as resin. The mounting base 2 has a spin-welded part 6 that is spin-welded to a recessed part 5 from which the edge of the molded product 4 protrudes, and a cylindrical threaded part 11 that projects upward from the center of the spin-welded part 6. A convex portion 12 is formed on the same circumference on the upper surface, and a protrusion 8 is formed on the peripheral edge. The clip 3 is made of a cylindrical body with a conical head, has a threaded part 13 on the inner periphery of the lower part to be screwed into the threaded part 11, and is elastically inserted into the mounting hole 10 of the vehicle body panel 9 on the side wall part. A clip portion 14 that is engaged with the clip portion 14 and a fin portion 15 that sandwiches the vehicle body panel 9 between the clip portion 14 and the clip portion 14 protrude to the outer periphery, and a protrusion 16 that engages with the recess portion 12 protrudes from the lower end. The recess 12 and the protrusion 16 constitute a locking portion.

In the mounting structure for a synthetic resin molded product for a vehicle having the above configuration, as shown in FIG. 4. As shown in Figure 4, screw the threaded part 13 of the clip 3 into the threaded part 11 of the mounting base 2 to a depth such that the distance l from the back surface of the molded product 4 to the vehicle body panel 9 is a predetermined distance. . At this time, if the screw-in depth exceeds a certain level, the protrusion 16 will be screwed in beyond the recess 12, and when screwing is stopped, the protrusion 16 will be locked in the recess 12, causing vibrations during product transportation or while the car is running. Loosening or tightening due to rotation is prevented. Then, as shown in FIG.
is inserted into the mounting hole 10 of the vehicle body panel 9, the clip portion 14 is engaged, and the vehicle body panel 9 is sandwiched between the clip portion 15 and the fin portion 15, and the molded product 4 is attached to the vehicle body panel 9.

When installing, the clip 3 can be installed at any desired height by adjusting the screwing depth of the threaded portion 13.

FIG. 6 is a sectional view of a mounting base of another embodiment, FIG. 7 is a plan view thereof, and FIG. 8 is a sectional view showing a state during installation. In this embodiment, a large number of protrusions 17 are provided on the same circumference on the upper surface of the spin welding part 6 of the mounting base 2 as a locking part, and the protrusions 16 of the clip 3
It is designed to engage with and prevent rotation.

In the above embodiment, the mounting base 2 has a thread, and the clip 3 has a female thread, but the reverse may be used. Further, although the mounting base 2 is provided with a recess or a protrusion and the clip 3 is provided with a protrusion as a locking portion, the opposite may be used, or other structures may be used.

[Effect of idea]

According to the present invention, the mounting base of the mounting clip and the clip are connected by the screw part, and rotation is prevented by the locking part, so the distance from the synthetic resin molded product to the object to be attached becomes large or small. Since the distance can be kept constant without loosening, and the distance does not vary due to external factors, it is possible to easily and stably attach the molded product.
