Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cover member for a side sill in an automobile.

2. Description of the Related Art In automobiles, a cover made of synthetic resin such as polypropylene, called a scratching plate or scuff, is attached to the upper surface of the side sill facing the lower surface of the side door. Usually, damage such as local wear and rust is prevented (see, for example, Japanese Utility Model Application Publication No. 136862/1986).

Also, the lower surface of the side sill or the outer side surface is susceptible to rust due to muddy water, and when driving on gravel roads, pebbles thrown up by the front wheels may hit the lower surface or outer side surface of the side sill and damage it, or weeds, etc. When driving on rough roads with growing grass, weeds and the like can scrape and damage the lower surface of the side sills. Some models are equipped with side sill covers.

Problems that the invention aims to solve However, in the past, the skirt cover that covers the upper surface of the side sill and the side sill cover that covers the outer and lower surfaces of the side sill were manufactured as independent parts, and each was attached to the side sill separately. The number of parts increases, the cost of parts increases, and the number of man-hours required for mounting the parts on the side sills is tedious.

Means for Solving the Problems In the present invention, a scuff portion that is bonded and fixed to the upper surface of the side sill and a side sill cover portion that is bonded and fixed to the outer surface and lower surface of the side sill side are connected by a thin self-hinge portion, and the side sill cover portion It has a front extension part and a rear extension part that extend forward and backward from the front end and rear end of the tire, respectively, and are joined and fixed to the lower surface of the side sill, and are attached to the lower part of the rear edge of the front tire house at the ends of the front extension part and the rear extension part. The present invention is characterized in that the cover member is integrally formed of a synthetic resin material and has a splash board portion and an air flap portion attached to the lower front edge of the rear tire house.

Function: First, the cover member formed in the developed shape as described above is joined and fixed to the upper surface of the side sill by first joining and fixing its scuff part, and then the side sill cover part is rotated downward about the self-hinge part, and the outer surface of the side sill is rotated. and the lower surface, the front extension part and the rear extension part are respectively joined and fixed to the lower surface of the side sill, and the splash board part and the air flap part are respectively attached to the lower part of the trailing edge of the front tire house and the lower part of the leading edge of the rear tire house. Skatuff part and side sill cover part,
The front and rear extensions prevent the side sills from wear and tear and rust, the splash board functions as a mudguard, and the air flap improves aerodynamic performance during driving.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, 1 is a side sill, 2 is a cover member attached to the surface of the side sill 1, and the cover member 2 is shown in FIGS.
As shown in the figure, a scuff portion 21 that covers the upper surface 11 and inner surface 14 of the side sill 1 and a side sill cover portion 22 that covers the outer surface 12 and lower surface 13 of the side sill 1 are connected by a thin cell hinge portion 23. The side sill cover part 22 is formed in an integrally connected structure, and a part of the side sill cover part 22 that covers the side sill lower surface 13 is extended in the front and back, and the end of the front extension part 24 has a lower front edge of the front tire house 3 of the vehicle body. A splash board section 25 is formed to be attached around the rear extension section 26.
An air flap portion 27 is formed at the end of the vehicle body and is attached to the lower front end of the rear tire house 4 of the vehicle body. The cover member 2 having the above-mentioned components is integrally formed of synthetic resin such as polypropylene resin.

The cover member 2 integrally constructed as described above has a shape at the time of product molding as shown in FIG.
The part of the side sill cover 22 that covers the upper surface 11 of the side sill 1 and the part of the side sill cover 22 that covers the outer surface 12 of the side sill 1 are connected in a nearly flush state. 4
As shown in the figure, the side sill cover part 22 is attached to the upper surface 11 and the inner surface 14 of the side sill 1, and then the side sill cover part 22 is rotated about the self-hinge part 23 as shown by the arrow A in FIG. 12 and the lower surface 13, and as shown in FIG.
By engaging the flange portion 13a formed on the inner edge of the side sill 1, the inner surface 1 of the side sill 1
4. All surfaces of the upper surface 11, outer surface 12, and lower surface 13 can be continuously covered by the cover member 2.

Next, the front and rear extensions 24 and 2 of the cover member 2
6 is attached to the surface of the lower surface 13 of the side sill 1, a splash board part 25 is attached to the lower part of the rear edge of the front tire house 3, and an air flap part 27 is attached by going around the lower part of the front edge of the rear tire house 4.

The above-mentioned cover member 2 is attached by attaching the cover member 2 by attaching screws at a plurality of places, such as the part covering the inner side surface 14 of the side sill of the skirt part 21, etc., and fixing the other parts, for example, by partially attaching the attachment material 5, etc. This may be accomplished by adhesion or engagement using an engaging portion 22a formed on the cover member 2.

In FIG. 4, reference numeral 6 indicates a floor mat laid on the floor 7, 8 indicates a weather stop for a door stop, and 9 indicates a side door. The portion of the scuff portion 21 that covers the side sill inner surface 14 is the floor mat 6 as shown in the fourth figure. It also has the function of processing the side terminal.

FIG. 5 shows a second embodiment of the present invention.
In this example, the scuff portion covering the inner side surface 14 of the side sill of the embodiment shown in FIGS. 2 to 4 is omitted, and the scuff portion 21 is replaced by the weather stop 8
The structure is such that only the upper surface 11 of the side sill on the outer side is covered, and the inner surface 14 of the side sill 1 is structured to cover the side of the floor mat 6 by rising up. The mounting structure etc. of the cover member 2 are the same as those shown in FIGS. 2 to 4 above, and the same reference numerals as in FIGS. 2 to 4 represent the same parts.

Effects of the invention According to the invention configured as described above, the scuff that covers the upper surface of the side sill and the side sill cover that covers the outer surface and lower surface of the side sill, which were conventionally formed as separate parts, are connected by a thin self-hinge part. In addition to integrally forming the side sill cover, the splash board and air flap, which were conventionally manufactured as independent parts and attached to the vehicle body separately, are now integrally formed with the side sill cover, resulting in a significant reduction in the number of parts. In addition to significantly reducing parts costs,
This can also reduce the number of installation steps, and can bring about a great practical effect.
