Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a mounting structure for a mudguard that is mounted on the outer surface of a side sill of an automobile.

BACKGROUND OF THE INVENTION Mudguards for automobiles are known to protect the vehicle body from chipping by covering the outer surface of the side sill from the rear edge of the front wheel arch to the front edge of the rear wheel arch.

An example of this will be explained with reference to FIGS. 10 and II. Reference numeral 1 indicates a side sill, and the lower wall of the side sill 1 has a section approximately U-shaped in cross section from the rear edge of the front wheel arch portion 2 to the rear of the side sill 1. A lower edge flange 3a of the shaped front mudguard 3 is attached by a screw grommet 4.

Further, the upper edge flange 3b of the front mudguard 3 is closely arranged on the outer surface of the side door I with the sole material 5 interposed therebetween.

Then, the insertion part 7a of the rear mudguard 7 that covers the rear part of the side sill I and the front edge of the rear wheel arch part 6 is inserted into the rear end of the front mudguard 3, and this insertion part 7a is inserted into the side sill l of the front mudguard. It is fixed together with 3.

The upper rear end of the rear mudguard 7 is fastened to the rear wheel arch portion 6 with screws 8.

Therefore, the mudguard can protect the rear edge of the front wheel arch portion 2, the outer surface of the side sill 1, and the front edge of the rear wheel arch portion 6, and extend the lower rear end of the rear mudguard 7 downward. This also aims to improve aerodynamic characteristics.

This similar structure is shown in, for example, Japanese Unexamined Patent Publication No. 155175/1982.

Problems to be Solved by the Invention However, with the conventional mudguard mounting structure described above, there is a risk that the rear mudguard 7 and the side sill 1 may be damaged when a rearward input load is applied to the rear mudguard 7 due to a curb or the like. There is a problem with this.

In particular, when the lower rear end of the rear mudguard 7 is extended downward in order to improve aerodynamic characteristics, this portion is likely to come into contact with a curb or the like, making the above problem more pronounced.

Therefore, the present invention provides a mudguard mounting structure that can prevent damage to the rear mudguard due to input from the road surface and improve the appearance quality.

Means for Solving the Problems A mudguard mounting structure in which a cap portion covering the front edge of a rear wheel arch portion is attached to the rear end portion of a mudguard body fixed along a side sill, the cap portion being attached to either one of the mudguard body and the cap portion. An insertion piece is provided along the longitudinal direction of the mudguard body, while a fitting part for receiving the insertion piece is formed on the other side, and a fitting part is formed on either the mudguard body or the cap part in the longitudinal direction of the mudguard body. A mounting piece with a U-shaped mounting part at the tip and a tapered wall thickness is provided along the same line, and a mounting hole that matches the mounting part of the mounting piece is formed on the other side. The mudguard main body and the cap portion are attached by inserting the attachment piece into the fitting portion and tightening the attachment portion of the attachment piece and the attachment hole.

When a rearward input load is applied to the action cap part by a curb or the like, either directly or indirectly through the mudguard body, the engagement between the insertion piece and the fitting part is easily released and the cap part tapers off. The mounting part of the tapered mounting piece and the mounting hole are removed, and the cap part is separated from the mudguard main body without being damaged.

Furthermore, the mudguard body is composed of a mudguard body and a cap part attached to the rear end of the mudguard body, so that the joint between the mudguard body and the cap part is made inconspicuous.

Example An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 9, reference numeral 9 indicates a mudguard, and this mast guard 9 covers the outer surface of the side sill 12 from the rear edge of the front wheel arch portion 1O to the front edge of the front wheel arch portion 11, and covers the mudguard body I3 and the rear end. The cap part I4 is attached to the cap part I4.

As shown in FIGS. 1 to 8, the mudguard main body 13 has a side sill attached to a side wall 13a that covers the side sill 12 from the side.
2 has a flange portion 16 tightened by a screw grommet 15 on the lower wall thereof, and the lower rear end thereof extends downward. As shown in FIGS. 7 and 8, the side wall 13a is fixed to the side sill 12 via a bracket 17 with a clip l8.

The mudguard main body 13 is provided with two fitting ribs 19 as fitting portions on the inner edge of its rear end, and a mounting hole 20 is formed in front of the fitting ribs 19.

On the other hand, the cap portion 14 is formed with a flange portion 2l as an insertion piece that is inserted into the fitting rib 19, and
A U-shaped mounting portion 22 at the tip corresponding to the mounting hole 20 above.
and a mounting piece 23 having a tapered wall thickness.
is provided.

Further, the flange portion 21 of the cap portion 14 and the mounting piece 23 of the mudguard main body 13 are both attached to the mudguard 9.
It is formed along the longitudinal direction.

Here, the lower rear end of the mudguard main body 13 is formed to extend downward and guide air from the front side downward, thereby improving aerodynamic characteristics.

Then, the flange portion 2 of the cap portion I4 is attached to the fitting rib 19 of the mudguard body 13 attached to the side sill 12.
1, align the mounting part 22 of the mounting piece 23 of the cap part 14 with the mounting hole 20 of the mudguard main body l3, and tighten the mounting part 22 of the mounting piece 23 and the mounting hole 20 from below with the screw grommet 15. .

As shown in FIG. 7, the upper end of the cap portion 14 is connected to the sole outer panel of the fender panel 25 and the side sill 12 by a screw grommet 24. 2a.

According to the above embodiment structure, for example, the mudguard body l3
When a curb or the like collides with the lower part of the rear end and a rearward input load F acts on the lower end of the cap part 14, the lower end of the cap part 14 bends rearward around the upper end fixed by the screw grommet 24. to counter this load F.

That is, the attachment piece 23 of the cap part 14 is attached to the mudguard main body l3 by the U-shaped attachment part 22, and the wall thickness of the attachment piece 23 is formed into a tapered shape, and the flange part 21 of the cap part 14 is Mudguard body 13
The lower end of the cap portion 14 easily separates from the mudguard main body 13 due to the load F because the cap portion 14 is simply inserted into the fitting rib l9 of the cap portion 19.

Therefore, there is no possibility that the cap portion l4 is damaged as in the conventional case.

Furthermore, since the mudguard 9 is composed of the mudguard main body 13 and the cap part 14 attached to the rear end, and the joint between the cap part l4 and the mudguard main body l3 is inconspicuous, the mudguard 9 can maintain a sense of unity with the vehicle body. It is possible to improve the appearance quality.

Note that the present invention is not limited to the above embodiments, and for example, the mounting piece 23 may be provided on the mudguard main body l3, the fitting rib 19 may be provided on the cap portion l4, or the fitting rib 19 may be provided on the cap portion l4.
The upper end fixing point may be abolished.

Effects of the Invention As explained above, according to the present invention, the main body of the Masodo Guard and the cap part have a U-shaped attachment part at the tip and the insertion piece is inserted into the fitting part, and the wall thickness is tapered. Since the formed mounting piece is integrated by fixing it to the other mounting part, when a rearward force is applied to the cassop part, for example from a curb, the cap part will separate from the mudguard, and the cap part etc. This has the effect of preventing damage to the product.

Further, since the cap portion is attached to the rear end of the mudguard body, the joint between the cap portion and the mudguard body becomes less noticeable, thereby improving the appearance quality of the vehicle body.
