Description

[Detailed description of the invention] This invention is a mounting structure for synthetic resin molded parts for automobiles.
In particular, it relates to the setting of gaps when a plurality of divided molded products are integrated.

Conventionally, synthetic resin molded products for automobiles such as rear finishers are constructed in a longitudinal shape by combining three molded product bodies 1 and 2 with each other, as shown in FIG. As shown in Fig. 2, the molded product bodies 1, 1 on both end sides are made up of a channel-shaped outer frame 3 with an inner frame 5 with a portion 4 protruding outward, and a cushioning material is attached to the edge. 6 is provided. Also, a boss 7 is made to protrude from the inner side of the outer frame 3, and a bolt 8 is attached to this boss 7.
After fitting and fixing the head 9 of the bolt 8 into the mounting hole 11 provided in the automobile panel 10,
It is fixed by tightening in step 2. Center side molded product body 2
has the same configuration as the element body 1 except that the inner frame 5 is omitted. In this case, the element body 2 has gaps l1 and l2 of a constant width between the element bodies 1 and 1 on both sides, and this gap l
It is attached so as to partially cover 4 at both ends of the element body 2 so as to maintain the angles 1 and 12.

However, according to the above configuration, the diameter of the hole 11 is set large in order to facilitate the insertion of the bolt 8, and therefore, when the molded article body 2 is attached, it is easy to cause a positional shift in the lateral direction, and the gaps l1 and l2 are This has the disadvantage that the size is fixed in a different state as shown in the figure.

An object of the present invention is to eliminate the above-mentioned drawbacks by providing a regulating member that regulates the lateral movement of the molded article body, and will be described in detail below using examples.

4 to 9 are configuration diagrams showing an embodiment of the mounting structure for an automotive molded product according to the present invention,
In each figure, a protrusion 21 that enters the inner surface of the molded product element 2 on the center side is provided at the end of the molded product element 1, 1 via a step 22, and a through hole 23 is formed in the protrusion 21. An elastically deformable protrusion 24 is integrally formed on the inner peripheral edge of the through hole 23. The projecting piece 24 may be provided on the inner surface of the protrusion 21, or may be provided on the outer surface as shown in FIG. 10, or may be provided in the middle thereof. In short, this protruding piece 24 is attached to the molded article body 1, 1
It is sufficient if the mold structure is the simplest when injection molding is carried out integrally with the
As shown in the figure, the ease of assembly is best if it is provided on the inner side. In addition, the protruding piece 24 is tapered,
It is also desirable to set the inclination angle to 45 degrees or more. On the other hand, a cylindrical projection 41 is integrally formed at a position corresponding to the hole 23 on the inner surface of the end of the molded article body 2 on the central side. The protrusion 41 has an outer shape similar to that of the hole 2.
The diameter of the hole 23 is set to be smaller than the diameter of the hole 23, and the height thereof is set to be larger than the depth of the hole 23.

As shown in FIGS. 7 and 8, the molded product elements 1, 1 and the molded product element 2 configured in this way are first assembled into a boss 2 formed on the inner surface of the elements 1, 1 on both sides.
The mounting bolts 26, 36 fixed to the body panels 5, 35 are inserted into holes formed in the body panels P1, P2, and firmly fixed with nuts or the like from the inner surface of the body panels.

After that, the molded product body 2 on the center side is first placed in such a way that the protrusion 41 molded on the end thereof fits into the hole 23, and the attachment part of the attachment bottle formed on the inner side enters the hole provided in the panel. When one side is pushed in, the protrusion 41 comes into contact with the protruding piece 24 as shown in FIG. 6, and the molded article body 2 on the center side is inserted in a state where it is shifted to the right side in the figure. Next, when the left side of the element body 2 is inserted in the same way, the element body 2 as a whole is drawn to the left side as shown in FIG. 6, and the center part is fixed with a nut from the inner side of the panel with the left and right projections 24 balanced against each other. do. In this way, the molded article body 2 is uniformly applied with force in the direction of the body 1 by the projecting pieces 24, 24, so that a constant gap l1, l2 is maintained. In other words, the positions of the molded element 2 are accurately and evenly distributed on the left and right sides due to the tension between the two projecting pieces 24, so that the gaps l1 and l2 on the left and right sides are the same, and the molded element 2 can be attached without any care. Also, loss of aesthetic appearance due to non-uniformity of the left and right gaps l1 and l2 can be prevented. This is because, as shown in FIG. 6, the dimension m1 of the end portion of the element body 1 is approximately 50 mm at most, and the dimension m2 of the element body 2 is also similar. Since the molded article bodies 1, 1 and the molded article body 2 are injection molded, the dimensions of these parts do not vary significantly at about 50 mm. Further, when the angle of the protruding piece 24 is set to 45 degrees or more, for example about 60 degrees,
The force with which the projecting piece 24 tries to push back the molded product body 2 until it is fixed with bolts is weak, so the operator does not have to keep pressing the molded product body 2 one by one during the installation work, and the tapered shape When it is made to be, the protrusion 2
4 can be prevented from being fundamentally damaged and no longer functioning.

The present invention can also be applied to side shields for bumpers, and combination parts of front grilles and left and right headlamp bezels. In addition, the protruding piece 24
may be directed toward the central molded article body.
