DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front fender mounting structure.

[0002]

2. Description of the Related Art As a conventional mounting structure for a front fender, for example, the one shown in FIGS. 5 and 6 is known (for a similar technique, see Japanese Utility Model Laid-Open No. 63-173885).

[0003] E is an engine room of an automobile, and a hood ridge 1 having a closed cross section is formed on both left and right sides thereof (only the right side structure is shown in the figure as a representative). A strut housing 2 is formed in a middle part of the hood ridge 1, and an end of a cowl panel 3 along the vehicle width direction is connected to a rear end part. 4 is a front pillar, and 5 is a front window panel.

[0004] Reference numeral 6 denotes an engine hood.
To cover the top of the This engine hood 6
Is supported by a hood hinge 7 so that it can be opened and closed. The hood hinge 7 has a structure in which a hinge bracket 8 attached to the cowl panel 3 and a hinge arm 9 attached to the engine hood 6 are pivotally supported by pins 10.

[0005] A front fender 11 is attached to the outside of the hood ridge 1. The front fender 11 is integrally press-formed with a vertical wall 12 facing downward from an inner upper edge 11a. At the lower end of the vertical wall 12, a drip flange 13 having a rib 13a at an end is formed. Then, the drip flange 13 is spot-welded to the upper surface of the front fender 11 (indicated by a mark * in the figure indicates a spot welding point). The drip flange 13 allows the water flowing between the engine hood 6 and the front fender 11 to be drained. Drip flange 1 of this front fender 11
3 is substantially horizontal, but since the inside upper edge portion 11a is shaped so that the rear is gradually raised, the vertical width of the vertical wall 12 also increases toward the rear, and is the largest at the rear end portion 14 of the front fender 11. The vertical width H is obtained.

[0006]

However, in such a conventional technique, the vertical width H of the rear end portion 14 of the front fender 11 is increased, and
It is difficult to perform deep drawing by press forming of a part, which is disadvantageous in terms of formability. Further, the large vertical width H of the rear end portion 14 is disadvantageous in that the plate removing property (yield) from the material and the positional accuracy of the inner upper edge portion 11a of the front fender 11 are improved.

In addition, if the vehicle body (hood ridge 1, cowl panel 3, etc.) is shared and only the shape of the front fender 11 is changed to obtain a vehicle of a different design, depending on the vehicle type, the vertical wall In some cases, the upper and lower widths H of 12 become too large to allow deep drawing. In such a case, it is necessary to form the vertical wall 12 once with the upper and lower widths H that can be formed, and to attach the vertical wall 12 with a bracket (not shown) of another component between the rear end portion 14 and the hood ridge 1. is there. Accordingly, the necessity of a bracket for another component leads to an increase in the number of components and cost, which is not preferable.

The present invention has been made by paying attention to such conventional technology, and can improve the formability of the front fender and obtain various shapes according to the vehicle type without increasing the number of parts. The present invention provides a mounting structure for a front fender.

[0009]

A drip flange is attached to the embossed portion .

According to the first aspect of the present invention, at least the rear portion of the drip flange is gradually inclined upward toward the rear, so that the vertical width of the vertical wall at the rear end does not increase, and the front portion does not become large. The formability of the fender is improved. Therefore, it is possible to form front fenders of various shapes according to vehicle types without worrying about moldability. Also, by inclining the rear part upward, a gap is created between the rear end of the drip flange and the hood ridge,
Since the upward projection is formed on the hinge bracket, the rear end can be securely attached to the projection. Furthermore, since the rear part of the drip flange is inclined upward, the front side of the drip flange is relatively lowered, and drainage by the drip flange is improved. In addition, it matches the drip flange inclination condition.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. In addition, the same reference numerals are given to portions common to the related art, and overlapping description will be omitted.

The inner upper edge 15a of the front fender 15
, A vertical wall 16 facing downward is formed, and a drip flange 17 having a rib 17a is formed at a lower end of the vertical wall 16. The drip flange 17 has a state in which portions other than the front end portion 18 are gradually inclined upward toward the rear. Therefore, the vertical width h at the rear end 19 of the vertical wall 16 of the front fender 15 is also small. Therefore, when the front fender 15 is press-formed, the degree to which the rear end portion 19 of the vertical wall 16 is deep drawn is reduced, and the forming is greatly facilitated.

On the other hand, a hood hinge 21 for opening and closing the engine hood 20 is provided on the vehicle body.
Is provided. The hood hinge 21 has a structure in which a hinge arm 22 attached to the engine hood 20 and a hinge bracket 24 attached to the rear end of the hood ridge 23 are pivotally supported by pins 25. Food Ridge 2
The hinge bracket 24 attached to 3 has a support piece 26 for supporting the hinge arm 22 on the outside, has a hook piece 27 on the inside, and is formed as a "protruding part" bent upward in a front end at a front end. Mounting piece 28. These support pieces 26, hook pieces 27, and attachment pieces 28 are all integrally formed when the hinge bracket 24 is formed. The upper surface portion 29 of the mounting piece 28 has a height corresponding to the rear end portion 19 of the drip flange 17 and is inclined forward and downward corresponding to the drip flange 17. 30 (see FIG. 2) is also formed. The hook piece 27 can be engaged with the curved edge 22a at the rear end of the hinge arm 22, and the hook piece 27 is attached to the curved edge 2a of the hinge arm 22 during a vehicle collision.
The engagement of 2a prevents the engine hood 20 from retreating.

On the other hand, on the upper surface of the hood ridge 23, two embossed portions 31, 32 are formed in front and rear. The two embossed portions 31 and 32 are connected to the drip flange 17.
The embossed portion 32 on the rear side is formed higher than the embossed portion 21 on the front side, and the upper surfaces of the embossed portions 31 and 32 are in an inclined state corresponding to the drip flange 17. I have.

Then, the drip flange 17 of the front fender 15 is placed on the hood ridge 23, and the front end 18 of the drip flange 17 is spot-welded to the upper surface of the hood ridge 23. Corresponding to the embossed portions 31, 3
Spot welding is performed on the upper surface of No. 2 (* mark in FIG. 1 indicates a spot welding point). Further, the rear end 19 of the drip flange 17 is attached to the upper surface 29 of the attachment piece 28 of the hinge bracket 24 with a bolt 33.

Since the drip flange 17 is gradually inclined upward toward the rear, a gap S is provided between the drip flange 17 and the hood ridge 23 (see FIG. 4).
As described above, since the drip flange 17 is attached to the embossed portions 31 and 32 and the attachment piece 28 of the hinge bracket 24, the attachment state of the front fender 15 is reliable and stable. Moreover, the embossed part 3
Since the reference numerals 1 and 32 are integrally formed with the hood ridge 23 and the mounting piece 28 is also integrally formed with the hinge bracket 24, the number of parts does not particularly increase.

Further, since the drip flange 17 is gradually inclined upward toward the rear, the drip flange 1
7, the front end portion 18 side is relatively lowered, and the drainage by the drip flange 17 is improved more than before. As described above, the front fender 15 in this embodiment has a small vertical height h of the vertical wall 16 at the rear end portion 19, so that not only the formability of the front fender 15 is improved, but also the stripping property from the material (the yield) ) And the position accuracy of the inner upper edge 15a is also improved.
In addition, since the vertical width h does not increase, even if the front fender 15 is changed into various shapes according to the vehicle type,
There is no problem in terms of moldability.

In the above embodiment, substantially the entire drip flange 17 of the front fender 15 is inclined, but, for example, only a part of the rear side of the drip flange 17 (for example, only the rear half) is inclined. It may be in the state where it was set. In addition, as the “projecting portion” of the hinge bracket 24, the mounting piece 28 having a structure in which the front portion of the hinge bracket 24 is bent in an upward crank shape is taken as an example, but the rear end portion 19 of the drip flange 17 can be mounted. Any other shape (for example, a cut-and-raised shape or an embossed shape) may be used as long as it has a shape. In addition, hinge bracket 2
4 is preferably formed integrally with the hinge bracket 24 so as not to increase the number of parts. However, the “projection” of another part is preferably formed on the hinge bracket 24 in advance. They may be attached integrally.

[0025]

According to the first aspect of the present invention, at least the rear portion of the drip flange is gradually inclined upward toward the rear, so that the vertical width of the vertical wall at the rear end does not increase. Thus, the formability of the front fender is improved. Therefore, it is possible to form front fenders of various shapes according to vehicle types without worrying about moldability. Also, by inclining the rear part upward, a gap is created between the rear end of the drip flange and the hood ridge,
Since the upward projection is formed on the hinge bracket, the rear end can be securely attached to the projection. Furthermore, since the rear part of the drip flange is inclined upward, the front side of the drip flange is relatively lowered, and drainage by the drip flange is improved. In addition, it matches the drip flange inclination condition.
