Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement in a fender structure for an automobile, which is composed of a combination of a side panel and a wheel house.

(Prior Art) Conventionally, as a vehicle fender structure of this kind, there is one as shown in FIG. 5 and FIG.

That is, the fender structure B of the automobile A has a side panel C and an inner wall (outer wheel house) D.
And an inner wheel house E, and a wheel house F is formed by the outer wheel house D and the inner wheel house E.

In this case, in the arc portion B1 of the fender structure B, the end portions of the side panel C and the outer wheel house D are bent at right angles toward the central portion (inward) of the automobile A, respectively. Forming flanges G and H, side panel C
The flange portion H of the outer wheel house D is brought into contact with the flange portion G of the above, and both flange portions G and H are spot-welded. At this time, since the assembling width dimension of the side panel C is finished according to the design drawing, the front surface D1 of the portion just above the flange portion H of the outer wheel house D is used for positioning thereof.
Is attached so as to contact the back surface C1 of the side panel C. That is, the side panel C and the outer wheel house D are formed by the flange portions G and H and the two mating surfaces of the back surface C1 and the front surface D1.

Further, as another conventional example, there is a device shown in FIGS. 7 and 8 disclosed in Japanese Utility Model Laid-Open No. 61-125877.

That is, in the structure of an automobile fender part in which the end portions of the fender panel A and the tire house B are overlapped and spot welded, the end portion of the fender panel A is bent toward the vehicle body center side (inward) to form a bent end portion C. Then, the tip of the bent end portion C is further bent upward to form the flange portion D, and the upper surface of the bent end portion C is slightly shorter than the bent end portion C and is centered in the vehicle body. Between the tip of the bent end portion E of the tire house B and the flange portion D of the fender panel A by overlapping the bent end portion E of the tire house B bent to the side and spot welding the both C and E. The pool portion F is formed on the tire house B, and the heat-softening sealing material G placed on the bent end portion E of the tire house B is used for the bent end portion E of the tire house B and the pool portion at the time of heating and drying in the coating process. It is designed to be adhered to F and

(Problems to be solved by the invention) However, in the former conventional example, there are two mating surfaces, a mating surface for spot welding and a mating surface for positioning. If the front surface of the wheel house F is not completely in close contact with the side panel C for positioning, it is difficult to obtain and manage the accuracy of the surface. Furthermore, since the electrodeposition liquid does not adhere to the mating surfaces, rust is likely to occur.

Further, in the latter conventional example, as in the above-described conventional example, there are two mating surfaces, a mating surface for spot welding and a mating surface for positioning. Also, the biasing and softening sealing material G placed on the bent end E of the tire house B is adhered to the bent end E and the pool F of the tire house B during the heating and drying in the coating process. However, there is a drawback in that only this processing work is additionally required.

(Means for Solving Problems) The present invention has been made to solve the above-described drawbacks. The arcuate end portions of the side panel and the wheel house are bent inward to form the flange portion. When it is formed, by forming a protrusion that contacts the back surface of the side panel near the flange of the wheel house, it is easy to manufacture and modify the press die, and it is possible to perform positioning during assembly. Moreover, it is an object of the present invention to provide a fender structure for an automobile that produces less low-grade sound and has an anticorrosive effect.

(Structure of Embodiment) The present invention will be described in detail below based on an embodiment shown in FIGS. 1 to 4. 1 is a perspective view of an automobile to which the fender structure according to the present invention is applied, and FIG. 2 is a perspective view of FIG.
II-II line sectional view, FIG. 3 is a III-III line sectional view of FIG. 1, and FIG. 4 is an exploded perspective view of a fender structure portion.

In the drawings, reference numeral 1 is an automobile, and although a pickup truck is shown in the drawing, it may be a wagon, a bus, an ordinary passenger car or the like. Reference numeral 2 denotes a fender portion, which is composed of a side panel 3, an inner wall (outer wheel house) 4, and an inner wheel house 5.

The end portions of the arc portion 6 of the side panel 3 and the inner wall 4 are bent toward the center of the automobile 1 in an orthogonal shape to form flange portions 7 and 8, respectively, and the flange portion 8 of the inner wall 4 is formed. On the circular arc surface 9 immediately above, the protrusions 10 that come into contact with the back surface of the side panel 3 are formed at predetermined intervals along the flange portion 8. Therefore, the arcuate surface 9 other than the protruding portion 10 does not contact the back surface of the side panel 3 and a gap 11 is formed.

In addition, the upper end of the side panel 3 is bent horizontally and vertically toward the center of the automobile 1 to form the upper end 13 of the luggage carrier 12, and the upper end of the arc surface 9 of the inner wall 4 is perpendicular to the upper part. Plates 14 are continuously provided, and an upper edge portion thereof is bent horizontally and vertically to form an upper edge portion 15.

Further, on the outer peripheral portion of the arc surface 9 of the inner wall 4,
The outer end of the inner wheel house 5 is welded, and the lower part of the inner wall 4 and the inner wheel house 5 form a wheel house 16. The inner end of the inner wheel house 5 is the floor board 17 of the cargo bed 12.
Is welded to.

(Operation of Embodiment) Therefore, upon assembly, the flange portion 8 of the inner wall 4 is placed on the flange portion 7 of the side panel 3, and both are fixed by spot welding. Further, the upper edge portion 15 of the inner wall 4 is inserted into the upper edge portion 13 of the side panel 3, and the vertical portions of both upper edge portions 13 and 15 are fixed by spot welding.

On the other hand, the end faces of the protrusions 10 formed on the circular arc surface 9 of the inner wall 4 are brought into contact with the back surface of the side panel 3 for positioning, and a gap 11 is formed between the protrusions 10. Further, the electrodeposition liquid enters from the gap 11 and adheres to the back surface of the side panel 3 and the outer surface of the inner wall 4.

(Effect of the Invention) As described above, according to the present invention, the end portions of the side panel 3 and the arc portion 6 of the wheel house 16 are bent inward to form the flange portions 7 and 8, respectively. Since the protrusion 10 that abuts on the rear surface of the side panel 3 is formed in the vicinity 9 of the flange portion 8 of the house 16 by contacting the side panel 3 with the protrusion 10 of the wheel house 16, 3 and the wheel house 16 can be positioned in the left-right direction during assembly.

Further, when manufacturing the press die for the wheel house 16, it is sufficient to manage the mating surface only on the end face of the protruding portion 10, so that the work of correcting the press die by the mating surface and the cost can be significantly reduced.

Furthermore, since the contact surface of the wheel house 16 with respect to the side panel 3 is as small as the protruding portion 10, the generation of low-grade sound due to poor contact can be significantly reduced. Gap on mating surface 11
As a result, the electrodeposition liquid easily penetrates, which is effective as a rust preventive measure.
