Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumper cover mounting structure in which a horizontal fender panel is screwed from a horizontal flange above a bumper arch of a bumper cover with a retainer having a grommet interposed therebetween.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional mounting structure of this kind, in which a flange 1b of a bumper arch 1a of a corner portion 1 of a synthetic resin bumper cover has a screw through hole 2 and a screw through hole 2.
An elongated escape hole 2a is formed forward of the through hole. An engaging hole 5a formed in the horizontal fender panel 5 that continues from the arch wheel 9 forward.
In the state where the grommet 3a formed in the retainer 3 is engaged, the screw 6 passes through the screw through hole 2 and the grommet 3
screwed into a. Thus, when an impact is applied to the bumper cover 1, the screw 6 moves along the long hole-shaped relief hole 2a.

[0003]

However, when the impact is even greater, the screw 6 is restrained by the front edge of the relief hole 2a and is forcibly moved rearward, as shown in FIG. 5 may be deformed or damaged.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a bumper cover mounting structure of the kind described at the beginning, which can reliably release the shock applied to the bumper cover.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a synthetic resin bumper cover is provided by interposing a retainer having a grommet which is engaged with the fender panel in a horizontal fender panel continuing forward from an arch wheel. In the mounting structure of the bumper cover to be screwed from the horizontal flange on the upper part of the bumper arch at the corner, in order to achieve the above-mentioned object, a flange is provided with a screw through hole corresponding to the screw diameter, and a retainer is provided with a grommet, Behind the grommet, a projection having a downward slope is formed from a position higher than the grommet toward the rear, and the fender panel has a grommet engagement hole and a wide grommet for the engagement hole. When the inclined surface retreats, a protrusion guide hole is formed to abut on the trailing edge, and the grommet is engaged with the engagement hole. Together, characterized in that screwing the screw into the grommet through the screw through-holes in a state of being invading projections protruding guide hole.

[0006]

When a shock is applied to the bumper cover, the projection retreats backward in the projection guide hole with the retraction of the retainer screwed to the flange. When a larger impact is applied, the inclined surface is guided by the trailing edge of the projection guide hole and escapes below the fender panel. Even larger, the slope is
The grommet is guided to the rear surface of the fender panel without contacting the rear edge of the projection guide hole, and the bumper arch is carried away to escape to the rear surface of the fender panel.

[0007]

FIG. 1 shows a mounting structure of a synthetic resin bumper cover according to an embodiment of the present invention.
The same or equivalent parts are denoted by the same reference numerals. Reference numeral 10 denotes a retainer interposed between the horizontal fender panel 5 that continues to the front of the arch wheel 9 and the horizontal flange 1b above the bumper arch 1a of the bumper cover corner 1. The retainer 10 has a grommet 11 and an inclined surface 1 having a downward slope rearward behind the grommet.
2a, and the upper end position of the inclined surface is a grommet 1
The protrusion 12 located higher than 1 is formed integrally.

The fender panel 5 has an engaging hole 15 of the grommet 11 at a position facing the screw through hole 19 of the flange 1b, and is wide so as to communicate with the engaging hole and function as a relief for the grommet 11. Further, a projection guide hole 16 through which the projection 12 enters is formed. Thereby, in the normal state, as shown in FIG. 2A, the screw 18 passes through the screw through hole 19 and the grommet 1 engaged with the locking hole 15.
1, and the projection 12 enters the projection guide hole 16 with a gap S left behind. When an impact is applied to the bumper cover, the projection 12 retreats backward in the projection guide hole 16 with the retraction of the retainer 10 screwed to the flange 1b. When a larger impact is applied, the protrusion 12
When the inclined surface 12a contacts the rear edge 16a of the projection guide hole 16 and escapes downward, and is larger, the inclined surface 12a is moved in the bumper cover corner portion 1 as shown in FIG. And the bumper arch 1a is released to the back surface in a free state. At this time, the height of the inclined surface 12a is adjusted by the screw 1 protruding from the grommet 11.
8 is higher than the front end, and therefore does not come into contact with the trailing edge 16a even if it retreats further.

[0009]

As described above, according to the present invention, even if the bumper cover receives a large impact, the inclined surface of the projection of the retainer is guided along the edge of the projection guide hole of the fender panel, so that the grommet can be mounted on the fender. Instead of abutting against the engagement hole of the panel, squeeze down below to make the bumper cover free. That is, even if the bumper cover comes off the fender panel, it can be easily restored to the normal position by elasticity without being damaged.
