Abstract

PURPOSE:To enable the number of part items of a bumper cover to be reduced by preventing damage to the protected portion of the body of an automobile which makes contact with the bumper cover when the bumper cover is moved under load. CONSTITUTION:A bumper cover 20, made of resin and attached to a body support 22 extending in the cross direction of an automobile body by a plurality of bolts spaced from one another in the cross direction, to cover the protected portion of the body, has a mounting portion 28 disposed above the support 22 and integrated therewith. The mounting portion has the same number of downwardly recessed mounting portions 34 as the bolts. The mounting portions 34 each have two vertical walls 36 and a bottom wall 38 having bolt holes 37 for passing bolts therein and brought into contact with the support 22. The vertical walls 36 are so formed that when the bolts are passed through the bolt holes and held in position, the heads of the bolts do not protrude.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumper cover for an automobile, and more particularly to a bumper cover formed of resin and attached to a support portion of a vehicle body by a plurality of bolts.

[0002]

2. Description of the Related Art As shown in FIG. 5, a plurality of bolts 11 (one shown in the drawing) 11 which are spaced in the width direction are attached to a support portion 10 of the vehicle body which extends in the width direction of the vehicle body. There is a resin bumper cover 13 that covers the protected portion 12. In the bumper cover 13, since the mounting portion 14 of the bumper cover is substantially flat, the bolt 11 is passed from above the mounting portion 14 to the mounting portion 14 and the support portion 10,
When the bumper cover is fixed by being screwed into the nut 15 welded to the support portion 10, the head of the bolt 11 projects above the mounting portion 14. As a result, as shown in FIG. 6B, when the bumper cover 13 moves from the position of the phantom line toward the vehicle body by the load applied to the bumper cover 13, the head of the bolt 11 hits a part of the protected portion 12 of the vehicle body. ,
The protected portion 12 of the vehicle body is damaged like a dent.

A spacer having a so-called hat-shaped cross-section is interposed between the upper portion of the bumper cover and the support portion of the vehicle body, the upper portion of the bumper cover and the spacer are joined together, and the spacer and the support portion are bolted. If the bolts are housed in the spacers as in the structure (see Japanese Utility Model Laid-Open No. 62-120052), the contact between the heads of the bolts and the protected parts of the vehicle body can be prevented.

[0004]

However, in the above structure, since the spacer is made of a steel plate, the spacer eventually moves together with the bumper cover and comes into contact with the protected portion of the vehicle body. It is impossible to prevent damage to the parts. In addition, the same number of spacers as the bolts is required, which increases the number of parts.

An object of the present invention is to provide a bumper cover for an automobile which can prevent damage to a protected portion of the vehicle body that comes into contact with the bumper cover when the bumper cover moves under load and reduce the number of parts. .

[0006]

SUMMARY OF THE INVENTION The present invention is a resin bumper cover which is attached to a support portion of a vehicle body extending in the width direction of the vehicle body by a plurality of bolts spaced in the width direction and covers a protected portion of the vehicle body. In addition, a mounting portion disposed above the support portion is integrally provided, and the mounting portion has the same number of mounting portions as the bolts that are recessed downward, and each mounting portion has two vertical walls. And a plurality of mounting portions having a bottom wall that is in contact with the supporting portion and has a bolt hole that allows each of the bolts to pass therethrough, and the vertical wall is in a fixed state in which the bolt penetrates the bolt hole. The head of the bolt is formed so as not to protrude.

[0007]

[Operation and Effect] The mounting portion of the bumper cover is mounted on the support portion of the vehicle body by the bolts penetrating the bolt holes of the respective mounting portions, and the bumper cover is put into use. Even if the bumper cover moves toward the protected portion of the vehicle body due to the load applied to the bumper cover and contacts the protected portion, the head of the bolt does not contact the protected portion of the vehicle body.

Since the head portion of the bolt does not come into direct contact with the protected portion of the vehicle body, damage to the protected portion due to the head portion of the bolt can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a bumper cover 20 includes a plurality of bumper covers (one shown in FIG. 2) spaced apart from each other in a support portion 22 of the vehicle body extending in the width direction of the vehicle body. It is made of resin, which is attached by the bolt 24 and covers the protected portion 26 of the vehicle body, and integrally includes an attaching portion 28 arranged above the support portion 22.

In the illustrated embodiment, the support portion 22 is a rear upper retainer and the protected portion 26 is a rear panel of the luggage room. The support portion 22 brings the luggage lid 30 covering the opening of the luggage room to the closed position, as shown in phantom in FIG.
It is arranged at a position close to the rear of the protected portion 26 so as to be covered with the luggage lid 30 when brought into close contact with.
Due to the close position and the portion 27 of the protected portion 26 that projects rearward, the movement of the bumper cover causes interference, which causes the above problem.

The bumper cover 20 is obtained by molding polypropylene, for example, and as shown in FIG.
The planar shape is approximately a U shape, and the mounting portion 28 is
The bumper cover 20 is provided at a front portion above the central portion.

The mounting portion 28 has the same number of mounting portions 34 as the bolts 24, which are recessed downward. As shown in FIG. 1, each mounting portion 34 has two vertical walls 36 and a bottom wall 38 having a bolt hole 37 through which each bolt 24 passes.
And the bottom wall 38 is arranged in contact with the support 22. As shown in FIG. 2, the vertical wall 36 is formed so that the head of the bolt 24 does not project when the bolt 24 is in a fixed state of penetrating the bolt hole. That is, the height and size of the vertical wall 36 are determined so that the head of the bolt 24 does not protrude from the vertical wall 36 when the head of the bolt 24 and the vertical wall 36 are projected from the side surface onto a vertical surface. ing. The vertical wall 36 is attached to the mounting portion 28 so as to satisfy this relationship.
From a horizontal portion 40 of the to the bottom wall 38.

In the illustrated embodiment, the mounting portion 28 is integral with the vertical wall 42 and is located in front of the vertical wall 42. The vertical wall 42 serves to prevent the lower end of the luggage lid 30 and the bumper cover 20 when the luggage lid 30 is in the closed position.
Even if there is a gap between the bumper cover 20 and the bumper cover 20
To increase the rigidity of the bumper cover 20.

The attachment portion 28 of the bumper cover 20 is attached to the support portion 22 by screwing the bolt 24 penetrating through the bolt hole 37 of each mounting portion 34 into the nut 44 previously welded to the support portion 22. Bumper cover 20
In addition to the attachment portion 28, the is attached to the vehicle body by clips at two positions on the left and right sides as is known per se.

As shown in FIG. 4a, the bumper cover 20
When the bumper cover 20 is attached to the support portion 22,
Is located rearwardly from the protected portion 26 of the vehicle body. As a result of the load being applied to the bumper cover 20, the bumper cover 20 moves toward the protected portion 26 of the vehicle body and, as shown in FIG. 4B, the vertical wall 3 of the mounting portion of the bumper cover 20.
Even if 6 comes into contact with the protected portion 26 of the vehicle body, the head of the bolt 24 does not contact the protected portion 26. As a result, damage to the protected portion 26 can be prevented.
