Abstract

PURPOSE:To respectively reduce the number of parts and man-hours of mounting work obviate the holder exclusively used for temporary stopping by respectively forming a pawl in either one of a bumper or a body panel further a hole, engaged with the pawl, in the other. CONSTITUTION:A front bumper 10 additionally provides a pawl 20 engaged with a hole 2 drilled in a front body panel 1a, and the front bumper 10, after it is temporarily stopped, is fixed by tightening a bolt not shown. Similarly, a rear bumper 30, after it is temporarily stopped by engaging with a hole 3 drilled in a rear body panel 1b a pawl 37 additionally provided in the rear bumper 30, is also fixed by tightening a bolt not shown. Thereafter, the front bumper 10 coats with a front hood 4 a slide mold hole 21 for forming the pawl 20. Similarly, also the rear bumper 30 coats with a license plate 5 a slide mold hole 38 for forming the pawl 37. Thus eliminating the necessity of any holder in exclusive use for temporary stopping, a number of parts and man-hours of mounting work are respectively decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to a bumper mounting structure, and more particularly to a temporary fixing structure for a bumper to a body panel.

b. Conventional technology In the case of a bumper for an automobile, the bumper is first temporarily attached to the body, and then screwed at appropriate locations to assemble it to the body panel.

FIGS. 4(a) and 4(b) show two examples of general mounting structures for such bumpers.

In the example shown in FIG. 4(a), a boss b is erected on the inner surface of the bumper side a, a holder C is fixed to the boss b with a screw d, and a hole f is formed in the side surface of the body panel e. , the bumper is temporarily fixed to the body panel e by pushing the tip of the holder C into this hole f.

In addition, in the example shown in Fig. 4 Φ), a holder C with a flange-shaped portion g is fixed to a boss b erected on the inner surface of the bumper side a with a screw d, and a body panel e
The bumper is temporarily fixed to the body panel e by fixing a bracket h to the side surface of the platen h with screws d, and fitting the flange g of the holder C to the platen h.

Problems to be Solved by the C0 Invention As described above, in the bumper mounting structure conventionally adopted, it is necessary to fix the holder C to the bumper, which not only makes the work complicated, but also makes it difficult to fix the holder C. Since the boss b is provided upright on the inner surface of the bumper, there is a sink mark l on the bumper surface, which spoils the appearance.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to eliminate the need to fix the holder to the bumper, thereby facilitating the installation work of the bumper.
Another object of the present invention is to provide a bumper mounting structure that can reduce the number of parts.

d. Means for Solving the Problems In the bumper mounting structure of the present invention, a pawl is integrally formed on one of the bumper and the body panel, a hole is formed on the other, and the pawl is engaged with the hole. The bumper is supported by the body panel.

e. Operation FIGS. 1 to 3 show a bumper mounting structure according to the present invention.

The illustrated front bumper 10 is molded from synthetic resin. This bumper 10 has tongue pieces 11.11 and 12.13 formed on the upper and lower edges of the bumper front part A,
A tongue piece 14.14 is formed on the back surface of the bumper side B. Bolt insertion holes 15, 1 are provided at both ends of the tongue pieces 11, 12, 13, 14 and the bumper front surface A.
6.1? , 18.19 are formed. Further, the tongue piece 11 has a claw 20 on its back surface.

Further, the rear bumper 30 is also molded from synthetic resin. In this bumper 30, tongue pieces 31, 32, and 32 are not formed on the upper edge of the bumper side C and on the back surface of the bumper side D, respectively. Bolt insertion holes 33.34° 35 and 36 are formed in the tongue pieces 31 and 32, both ends of the bumper rear surface C, and the license plate mounting portion C'. Further, in this rear bumper 30, a claw 37 is formed on the back surface of the license plate mounting portion C'.

The claws 20.37 of the front bumper IO and the rear bumper 30 are both integrally molded, and the claws 20.3 are attached to the tongue piece 11 and the license plate mounting portion C'.
Slide mold hole 2 for forming undercut part 7
1.38 is formed.

As shown in FIG. 2, the front bumper 10 has claws 2 inserted into holes 2 formed in the front body panel 1a.
0 and temporarily fixed to the front body panel 1a, and then fixed to the front body panel 1a by bolts (not shown) inserted through bolt insertion holes 15, 16, 17, 18° 19. Further, the rear bumper 30 is
As shown in FIG. 3, the pawl 37 is engaged with the hole 3 formed in the rear body panel 1b, and the rear body panel 1b is temporarily secured, and then the bolt insertion holes 33.34, 35.36
It is fixed to the rear body panel lb by a bolt (not shown) inserted through the lb.

In this way, the front bumper 1 installed on the vehicle body 1
0, the slide mold holes 21 formed to form the claws 20 are hidden from the outside by the front hood 4 that covers the upper part of the front bumper 10, and the rear bumper 30 is hidden from the outside.
The license plate 5 attached to the rear bumper 30 hides the slide mold hole 38 formed for forming the claw 37 from the outside.

In the above embodiment, holes 21.38 are formed in the bumpers 10, 3G to form the claws 20.37. Therefore, in the bumpers 10 and 30, the bumper 10.3
It is necessary to form the claws 21 and 38 in such a position that the holes 21.38 are hidden from the outside when the 0 is installed on the vehicle body l. However, the claw 20 without using the hole 21.38
37, the positions of the claws 21, 38 need not be limited to the above locations.

Further, in the above embodiment, the claw 21.38 is connected to the bumper 10.3.
0 and the holes 2 and 3 with which the claws 21 and 38 engage are formed in the body panels la and lb, but the claws are formed in the body panels Ia and lb and the holes are formed in the bumpers 10 and 30. You may.

10 Effects of the Invention As mentioned above, in the bumper mounting structure according to the present invention,
A holder is not required to temporarily fix the bumper to the vehicle body, so the work of assembling the holder to the bumper can be omitted.
This not only improves work efficiency, but also reduces the number of parts, which is advantageous in terms of parts management.
