Description

[Detailed Description of the Invention] This invention relates to the structure of resin parts for automobiles, such as radiator grilles.

Examples of conventional radiator grills include those shown in FIGS. 1 and 2, for example.

That is, a through hole 4a is formed in the vehicle body 4, and the screw grommet 3 is fitted into the through hole 4a, and the screw grommet 3 is inserted through the through hole 1b of the grill body 1a of the radiator grill 1 and the jtM hole 3a of the screw grommet 3. By screwing the tamping screw 1 large knee 24, which is a screwing member, the vehicle body 4
Attach radiator grill 1 to the.

However, in such conventional radiator grills, the grill body 1a and the screw grommets 3 are separate parts, so the screw grommets 3 are required for the number of mounting locations, increasing the cost of purchased parts. .

Further, it is necessary to take the time and effort to insert the required number of grommets 3 into the through holes 4a of the vehicle body 4 in advance.

Furthermore, there was a problem in that it was difficult to center each of the through holes 1b-3a-4a.

This idea was created by focusing on these conventional problems, and solved the above problems by integrally molding the grille body and the screw grommet, and adding the function of the screw grommet to the grille body. With the purpose of (゛).

This invention will be explained below based on the drawings.

FIG. 3 is a diagram showing an embodiment of this invention.

First, to explain the structure, 5 is a radiator grill body, a claw part 6 is molded integrally with the radiator grill body 5, and a tapping screw 2 is inserted into a hole 5a vertically penetrating the center of the claw part 6 and tightened. The claw portion 6 is configured to be pushed and expanded.

That is, the claw portion 6 is connected to the hole 5a, which is provided with a width narrower than the diameter of the screw 2, so as to be pushed and spread by the screw 2 when tightening, and to prevent the screw from falling out of the vehicle body mounting hole 4a when it is pushed and spread. The nail outer wall 5b has a convex shape.

Furthermore, a groove 5c having the same shape as the mounting hole 4a of the vehicle body 4 is provided at the base of the claw portion 6.

Next, the action will be explained.

When attaching the radiator grill 5 to the vehicle body 4, follow the steps below.

First, the mounting hole 4a of the vehicle body 4 is located at a position opposite to the claw portion 6.
It is temporarily attached to the vehicle body 4 by the spring action of the claw portion 6.

Next, use a tool to insert the tapping screw 2 into the screw hole 5.
Insert into a and tighten.

At this time, the integrally molded claw part 6 is pushed and expanded by the screw 2, and the convex part of the claw outer wall 5b is further pushed and spread than when it was inserted, and firmly bites into the attachment hole 4a.

Further, when tightening, the screw 2 is inserted while tapping the inner wall 6a of the claw part 6, and is firmly held by the claw part 6 by the spring action of the claw part 6, thereby preventing loosening.

As described above, the radiator grille main body 5 is firmly attached to the vehicle body 4.

In addition, the radiator grill body 5 may be damaged due to damage such as the claw portion 6 being broken.
If it becomes difficult to attach the radiator grille to the vehicle body 4, press a tool such as a screwdriver with a flat head shape along the groove 5c, and the groove 5c will be cut and the claw portion 6 and the radiator grille will be cut. The radiator grille body 5 can be reattached by making it separate from the main body 5, punching out six claws, and attaching another screw grommet (not shown).

As explained above, according to this invention, the structure is such that a claw part having a screw grommet function is integrally formed on a resin part for an automobile such as a radiator grill, and the claw part itself has a breakable part at the base of the claw part. Since the grooves are formed, there is no need to insert the required number of grommets into the mounting holes of the vehicle body in advance, unlike conventional methods, which reduces work man-hours ( Even if it is damaged by some external force, the claw can be easily punched out of the groove, so it is possible to attach a conventional screw grommet to the punched hole and attach it to the car body without having to discard the resin part itself. It has the effect of becoming.
