Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a structure for attaching synthetic resin molding to a vehicle body panel.

BACKGROUND TECHNOLOGY In general, screwing with stud bolts or bonding with double-sided adhesive tape is used to attach moldings to vehicle body panels, but especially in areas such as the door panel 1 that are susceptible to impact forces when opened and closed. Usually, the molding 3 is mechanically screwed and fixed to the vehicle body panel 1 using stud bolts 2 for firm attachment (see FIG. 1).

Conventionally, when the molding 3 is made of synthetic resin, the stud bolt 2 (see Fig. 2 a, b) is fixed to a metal pedestal 4 by welding or the like, and the pedestal 4 is integrated with the back of the molding 3. In addition to fitting into the hollow box 5 which is injection molded,
The bolt shaft is received in a keyhole-shaped notch 6 formed in the plane of the box 5 and is projected and fixed to the back surface of the molding 3. However, since this stud bolt 2 has no freedom at all, it cannot deal with the misalignment of the protruding position of the stopper hole on the vehicle body panel side and the bolt shaft, which often occurs, and even if they match up and are firmly screwed together. Even if it can be stopped, the thermal expansion and contraction of the synthetic resin molding 3 cannot be absorbed, causing distortions such as bulges in the molding body, and furthermore, if the nut 7 is screwed too far into the bolt shaft to securely fasten the molding 3, Molding 3
It is difficult to adjust the degree of tightening because the flat surface of the main body sinks.

DISCLOSURE OF THE INVENTION The present invention provides a mounting structure for a synthetic resin molding that can absorb misalignment with a stop hole on a vehicle body panel side and thermal expansion and contraction of the molding, and that can be easily installed with proper tightening. With the goal.

That is, in the mounting structure of the synthetic resin molding according to the present invention, a hollow box is integrally molded on the back side of the molding body corresponding to the stopper hole on the vehicle body panel side, and a rigid plate is inserted into the box. At the same time, a fixing hole with the same diameter as the car body panel side is formed in the plate surface of the rigid plate, and a relatively large opening is formed in the plane of the box, and an anchor bolt inserted from the car body panel side is inserted into the box. It is configured to fit into the fixing hole of the rigid plate through the opening.

Embodiment This will be explained below based on FIGS. 3 to 6.

This molding body 10 is formed by injection molding of synthetic resin, and a hollow box part 1 is provided on the back side at a position corresponding to a stopper hole on the side of the vehicle body panel 11 (see Fig. 5).
2, 12... are integrally molded at regular intervals. The boxes 12, 12... are for receiving rigid plates 13, 13... made by punching and forming metal plates, etc., and inside the boxes 12, 12, there is a molding body 10.
The rigid plate 13 can be inserted through the opening 12a formed in the rising flange of the flange. The rigid plate 13 is formed to be smaller than the internal space of the box 12, and is loosely inserted so that it can move freely to some extent within the internal space.
Moreover, this rigid plate 13 is connected to the insertion tip side 1.
3a is formed into an arrowhead shape, and a neck 13b cut out in a U-shape is provided so that the tip side 13a protrudes from the opening 12b formed on the deep side of the box 12, and the neck 13b is attached to the edge of the opening 12b. When fitted, the box 12 is press-fitted so that it cannot be removed from the box 12. In the illustrated embodiment, box 1
2 is formed with a relatively large rising dimension in order to separate the plane of the molding body 10 from the plane of the molding body 10,
A rigid plate 13 is inserted therein so that its lower surface is received and supported by a guide rod 12c. The plane of the box 12 and the plate surface of the rigid plate 13 have openings 12d, 1 which are aligned with each other.
3c, of which the opening 1 of the box 12
2d is formed relatively larger than the opening 13c of the rigid plate 13. These openings 12d, 1
Reference numeral 3c is for inserting an anchor bolt 14 (see FIG. 5), which will be described later, and the opening 13c of the rigid plate 13 is used as a stopper hole for locking the anchor bolt 14.

In attaching this molding 10 to the vehicle body panel 11, anchor bolts 14 are used which are inserted from the side of the fixing hole in the vehicle body panel 11. The anchor bolt 14 includes a main body portion 14d having an expanding claw and a bolt shaft 14b that is press-fitted into an insertion hole formed at the center of the axis of the main body portion. In this anchor bolt 14, first, the main body portion 14a is inserted through the fixing hole of the vehicle body panel 11 into the opening 12d formed in the box plane of the molding 10.
through it and insert it into the stopper hole 13c of the rigid plate 13. Next, the bolt shaft 14b is press-fitted into the insertion hole of the main body part 14a, and the expansion claws of the main body part 14a are pushed out and engaged with the edge of the stopper hole of the rigid plate 13. When the anchor bolt 14 is fixed to the rigid plate 13, the anchor bolt 14 cannot be removed, so that the molding 10 can be securely mechanically fixed to the vehicle body panel 11.

In the molding mounting structure configured in this way, the anchor bolt 14 is locked by the rigid plate 13, and the rigid plate 13 is connected to the box 12.
can move freely within the box 12.
Since the opening 12d formed in the plane of the molding is large, there is a misalignment between it and the fixing hole of the vehicle body panel 11, and even if the molding body 10 undergoes thermal expansion and contraction, the rigid plate 13 moves together with the anchor bolt 14. It is possible to absorb them. Further, since the anchor bolts 14 need only be press-fitted into the respective fixing holes, the molding 10 can be attached extremely easily and reliably.

In addition, when removing the molding 10, since the bolt shaft 14b of the anchor bolt 14 is threaded, the bolt shaft 14b can be easily removed by unscrewing it. The body portion 14a that has become worn out can be easily pulled out. In addition, the molding 10 is fixed with anchor bolts at several locations along the longitudinal direction.
The box can be mounted using one of them as a reference. In that case, a hole 12d' with the same diameter as the anchor bolt 14 is provided in the plane of the box at the reference point, and a horizontally elongated hole 12d'' is made in the other box plane. By providing this, the horizontally elongated opening 12d'' may absorb positional displacement and thermal expansion and contraction of the molding 10. In addition, if the molding portion of each box 12, 12... is biased to one side of the molding 10, a rib 15 is integrally molded on the flange portion of the other side, and the rib 15 is fitted into the notch of the vehicle body panel 11. can. Further, if about half of the molding is mechanically fixed with anchor bolts 14, the other half can be attached securely as a whole even if it is attached with double-sided adhesive tape.

Effects of the Invention As described above, according to the molding mounting structure according to the present invention, even if there is a misalignment between the fixing holes on the vehicle body panel side and the molding side, or thermal expansion and contraction occurs in the molding, each can be easily fixed. can be absorbed into
Furthermore, since the rigid plate is fixed with anchor bolts, the degree of tightening of the molding body can be made constant, no sink marks will occur on the surface, and the molding can be installed with simple work.
