[Industrial applications]

 The present invention relates to a mudguard assembly structure for an automobile.

[0002]

[Prior Art]

 In order to prevent muddy water or pebbles splashed up by a tire while a vehicle is traveling from hitting a vehicle body or a following vehicle, it is well known that a mud guard is provided on a bumper portion or a vehicle body portion behind the tire.

FIG. 7 is a schematic view showing an example of such a mudguard. Reference numeral 1 is a vehicle body of an automobile, 2 is a bumper arranged at a rear portion of the vehicle body, 3 is a tire, and 3 of the tire 3 is shown. The mudguard 4a is arranged on the rear bumper portion. The bumper 2 is fixed to the vehicle body 1 or a chassis frame (not shown).

FIG. 8 shows how the mudguard 4a is assembled to the bumper 2, and FIG. 9 shows the mudguard 4a after it is assembled. 10 is a cross-sectional view taken along the line AA of FIG. 9, and the reference symbol X in FIGS. 7 to 10 indicates the forward direction of the vehicle, and the reference symbol Y indicates the inside of the vehicle orthogonal to the forward direction X. ..

The mudguard 4a is located behind the tire 3 as shown in FIG. 7, and catches muddy water and pebbles splashed by the tire 3 while the vehicle is running, and hits the vehicle body 1 and the following vehicle. It is to prevent.

In order to mount such a mudguard 4a, as shown in FIGS. 8 and 9, the mudguard 4a is mounted on the bumper 2 behind the tire, and then the mudguard 4a and the vehicle body 1 are mounted. The mudguard 4a is fixed to the vehicle body 1 by inserting the bolt 7 into the mounting holes 5a and 6 formed in the and, and screwing the bolt 7 and a nut (not shown) to the bumper 2. Assemble.

As described above, the mudguard 4a is immovably fixed to the vehicle body 1, but is simply assembled to the bumper 2 and, as shown in FIG. 10, the edge portion 8a of the mudguard 4a. Is in contact with the outer side surface (the outer side surface of the vehicle) 9 of the bumper 2.

However, due to manufacturing variations of the mudguard 4a and the bumper 2, or variations in the assembling thereof, the edge portion 8a of the mudguard 4a does not adhere to the outer side surface 9 of the bumper 2 and is shown by a chain line in FIG. On the other hand, the edge portion 8a may locally rise from the outer side surface 9. When the edge portion 8a rises in this manner, a slight gap G is formed between the edge portion 8a and the outer side surface 9 of the bumper 2, and the appearance thereof is deteriorated.

Further, the edge portion 8a of the mudguard 4a is curved toward the outer side surface 9 of the bumper 2 as shown in FIG. 10 so that the gap G as described above does not occur, and the tip end of the edge portion 8a is the outer side surface. The mudguard 4a is formed so as to be in pressure contact with the inner surface 9 of the mudguard 4a. However, when the edge portion 8a of the mudguard 4a is curved as described above, the outer surface of the mudguard 4a, that is, the outer surface 10a and the outer surface 9 of the bumper 2 are There is a step S between the two and this, which loses the sense of unity between the two and inevitably reduces the appearance.

When assembling the mudguard 4a to the bumper 2 (FIG. 8), the operator positions the mudguard 4a with respect to the bumper 2 by visual inspection. The efficiency is unavoidable.

As described above, the inconvenience when assembling the mudguard 4a to the bumper 2 fixed to the vehicle body 1 has been described. However, even when the mudguard 4a is assembled not to the bumper but to the vehicle body and is fixed to the vehicle body, The same problem occurs just as I did. That is, the edge portion 8a of the mudguard 4a does not adhere to the outer side surface of the vehicle body, and the edge portion 8a floats up from this outer side surface to reduce its appearance, and the edge portion 8a of the curved mudguard is A step is formed between the outer surface of the vehicle body and this also causes a problem that the appearance is deteriorated.

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a state before the mudguard 4 is attached to the bumper 2, and FIG. 2 shows a state after the assembling. The symbol X in these figures indicates the forward direction of the automobile. Reference numeral Y indicates the inside of the vehicle. As can be seen from FIG. 1, FIGS. 1 and 2 show a state in which the bumper 2 is viewed from the inside of the bumper 2, that is, the side of the vehicle body 1.

The bumper 2 and the mudguard 4 assembled to the bumper 2 are made of a plate material such as a synthetic resin or a metal, and the edge portion 8 of the mudguard 4 has at least one, as shown in FIG. The individual engaging protrusions 20, 21, 22 are formed. On the other hand, the edge portion 11 of the bumper 2 is also formed with at least one engaging protrusion 23, 24 in the illustrated example.

In order to assemble the mudguard 4, first, the edge portion 11 of the bumper 2 already fixed to the vehicle body 1 (or chassis frame) and the edge portion 8 of the mudguard 4 are assembled as shown in FIG. wear. At that time, the engaging projections 20, 21, 22 formed on the edge portion 8 of the mudguard 4 are engaged with the inner side surface 25 of the bumper 2, that is, the bumper surface on the inside of the vehicle that cannot be seen from the outside. As shown in FIGS. 3 to 5, the engagement protrusions 21, 22, 23 of the mudguard 4 are engaged with the inner side surface 25 of the bumper 2, respectively. At that time, as shown in FIG. 4, a groove 26 is formed in the engaging projection 20, and the groove portion 26 and the protrusion formed on the edge portion 11 of the bumper 2 are fitted to each other. The side surface 25 may be engaged with the engagement protrusion 20.

After assembling the mudguard 4 to the bumper 2 in this manner, the bolt 7 is inserted into the mounting holes 5 and 6 formed in the mudguard 4 and the vehicle body 1 as before, and the nut 28 is screwed into the bolt. The mudguard 4 is immovably fixed to the vehicle body 1 by wearing and tightening. The overall appearance of the mudguard 4 after installation is substantially the same as that of FIG. 7, and prevents the muddy water and pebbles from hitting the vehicle body 1 or the following vehicle as in the conventional case.

According to the mudguard assembly structure described above, the engagement protrusions 20, 21, 22 of the mudguard 4 engage with the inner side surface 25 of the bumper 2, and the engagement protrusions 23, 24 of the bumper 2 cause the mudguard 4 to move. Since it engages with the inner side surface 27, the edges 8 and 11 of the mudguard 4 and the bumper 2 are assembled so as to be engaged with each other by their engaging projections, thereby preventing a problem that a gap is formed between them. it can. As a result, the edge 8 of the mudguard 4 does not need to be curved as in the conventional case, and the outer surface 9 of the bumper 2 and the outer surface 10 of the mudguard 4 can be formed as shown in FIGS. It is possible to keep them in a single state and enhance the sense of unity between them. In this way, the appearance of the mudguard 4 can be enhanced. Further, since each of the engaging protrusions 20 to 24 is not exposed to the outside of the vehicle, there is no possibility that the appearance is damaged by these protrusions.

When the mudguard 4 is assembled to the bumper 2, the engagement protrusions 20, 21, 22 of the mudguard 4 are engaged with the bumper 2, and the engagement protrusions 23, 24 of the bumper 2 are attached to the mudguard 4. Since they are engaged with each other, the mudguard 4 can be easily and correctly positioned with respect to the bumper 2 without any special care by the operator, and the assembling workability thereof can be improved. Particularly, in the illustrated embodiment, engaging protrusions 20 and 22 are formed on the front and rear portions of the mudguard 4, respectively, and these engage with the bumper 2 to position the mudguard 4 in the vertical direction, so that workability is improved. It is possible to mount the mudguard 4 in a predetermined correct position by remarkably increasing the height.
