DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front body of an automobile having a grill filler, and more particularly to a mounting structure of the grill filler.

[0002]

2. Description of the Related Art A pair of left and right fender panels, a radiator grill, a front bumper, and the like are mounted on a front portion of an automobile such as a passenger car. Further, depending on the type of vehicle, an elongated member called a grill filler may be mounted between the radiator grill and the bumper. Both ends of the grill filler are adjacent to the fender panel.

A conventional general mounting structure employed for mounting the grille filler on a vehicle body is such that the grille filler is screwed by a pair of left and right grille filler fixing brackets welded to the front of the vehicle body. I have. On the other hand, the front end of the fender panel adjacent to the grill filler is supported on the vehicle body via a fender mounting bracket welded to the vehicle body. Further, the bumper is fixed to the body via a bumper mounting bracket welded to the vehicle body.

[0004]

As described above, the conventional grille filler is assembled separately from the fender panel and the bumper. Therefore, in the case of an elongated member such as a grille filler, the grille filler can be accurately positioned with respect to the fender panel. It is difficult to assemble the grille filler and the fender panel with high accuracy in the position, and there is a case where a step is generated when the positions of the grill filler and the fender panel are vertically displaced in the adjacent portion.

In addition, since there is a limit in controlling the positional relationship between the lower surface of the grille filler and the upper surface of the bumper with high accuracy,
Design gaps were likely to occur, such as a discontinuous gap between the lower surface of the grill filler and the upper surface of the bumper and between the upper surface of the bumper and the fender panel.

Particularly, in the case of a front body employing a round headlamp, an arc-shaped curved line is formed along the contour of the headlamp at the front end of the fender panel and both ends of the grille filler due to the design. If the line becomes discontinuous due to the displacement of the curved line at the adjacent portion between the grill filler and the fender panel, the appearance around the grill is significantly reduced and the commercial value is impaired.

For this reason, it is desired to increase the accuracy of assembling the adjacent portions of the grille filler, the fender panel, and the bumper. However, the positions of the grille filler fixing bracket, the fender mounting bracket, and the bumper mounting bracket can be precisely adjusted. There is a limit in management, and there is a tendency that the above-mentioned problem is exacerbated by the limitation of the shape accuracy of the grill filler, the fender panel and the bumper, and there is room for improvement in this point.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a front body of an automobile having a grille filler capable of assembling a grille filler to a fender panel or a bumper with high accuracy and facilitating the assembly work. It is in.

[0009]

SUMMARY OF THE INVENTION The present invention, which has been developed to achieve the above object, comprises a pair of left and right fender panels mounted on the front left and right vehicle bodies, and a front bumper mounted on the front end of the vehicle body.

A mounting end face of a longitudinal end of the grill filler and a front end mounting portion of the fender panel are mounted on the supporting portion and both are mounted on the first supporting portion, and the bumper is mounted on the second supporting portion of each bracket. Characterized in that the upper end is mounted.

One example of the bracket is formed by bending a sheet metal, and includes a base fixed to the vehicle body, a first support protruding forward from the base, and a horizontal portion extending from a lower portion of the first support. A second support portion extending to the first support portion, and a weld nut provided on the first support portion and a bolt screwed to the weld nut are used to connect the mounting end surface of the grill filler and the front end mounting portion of the fender panel to the first position. It is preferable that the upper end mounting portion of the bumper is fixed to the second support portion by fixing to the first support portion and a weld nut provided on the second support portion and a bolt screwed to the weld nut.

[0011]

According to the grille filler mounting structure of the present invention having the above structure, the end of the grille filler and the front end of the fender panel are fastened together via the first support of the bracket.
At an adjacent portion between the grill filler and the fender panel, the two are assembled while maintaining a precise relative positional relationship with each other.
In addition, since the upper end of the bumper is supported by the second support portion of the bracket, the positional relationship between the lower surface of the grille filler and the lower surface of the fender panel with respect to the bumper is accurate near the portion adjacent to the grille filler and the fender panel. And a gap between the lower surface of the grille filler and the bumper or between the bumper and the fender panel is avoided.

The upper surface wall of both ends 32 in the longitudinal direction of the grill filler 16 is an arc-shaped curved surface 33 so as to follow the contour of the round headlamp 15.

At the ends of both ends 32 of the grill filler 16 in the longitudinal direction, a mounting end face 35 bent rearward is provided, and the mounting end face 35 is provided with a terminal mounting hole 36. An intermediate bracket 40 (shown in FIG. 8) is provided at an intermediate portion in the longitudinal direction of the grill filler 16, and the intermediate bracket 40 is fixed to the front auxiliary frame 42 of the body frame 17 by screws 41.

The upper part and the rear part of the fender panel 11 are:
It is fixed to the body frame 17 by well-known fixing means. The front end 45 of the fender panel 11 is provided with an arcuate curved surface 46 corresponding to the outer shape of the headlamp 15 when viewed from the front, and this curved surface 46 is continuous with the curved surface 33 of the grille filler 16. It is supposed to.

The front end 45 of the fender panel 11 is provided with a tongue-shaped front end mounting portion 50 facing the rear side, and the front end mounting portion 50 is provided with a fender front end mounting hole 51. A lower edge flange 52 facing inward is provided on the lower surface of the front end 45 of the fender panel 11.

A connecting hole 53 is provided at the rear of the lower edge flange 52, and a female screw portion 54 such as a grommet nut is mounted. A tongue-shaped lower mounting piece 55 protruding downward is provided at an intermediate portion of the lower edge flange 52 in the front-rear direction.
Is provided with a fender lower mounting hole 56. The fender lower mounting hole 56 is a long hole that is long in the front-rear direction of the vehicle body.

As shown in FIGS. 6 and 8, a pair of brackets 6 are provided on the left and right sides of the front portion of the body frame 17.
The front end 45 of the fender panel 11, the longitudinal ends 32 of the grille filler 16, and the upper end of the bumper side member 21 are assembled by brackets 61 and 62. Each of the brackets 61 and 62 has a symmetrical shape with respect to each other, and has a common basic structure. Therefore, one of the brackets 61 will be described below as a representative.

As shown in FIG. 1 or FIG. 4, the bracket 61 is a press-formed product of a steel plate formed in a substantially U-shape when viewed from above the vehicle body. That is, the bracket 61 includes a base 70 extending in a substantially vertical direction, and a base 70.
A first support portion 71 and a second support portion 72 projecting forward from the left and right sides of the vehicle body. At the lower edge of the first support portion 71, a third support portion 73 which is bent substantially horizontally toward the inside of the vehicle body is provided. The base 70 is welded to a bracket mounting wall 75 provided on the body frame 17.

Since the first support portion 71 is like a leaf spring, it can flex to some extent in the width direction of the vehicle body (in the horizontal direction in FIG. 3). A pair of upper and lower weld nuts 77 is fixed to the first support portion 71 as an example of a female screw portion. A weld nut 78 is also fixed to the second support portion 72 as an example of a female screw portion. A weld nut 79 is also fixed to the third support portion 73 as an example of a female screw portion. Instead of using a weld nut, the bracket 61 itself may be formed with a threaded hole.

As shown in FIGS. 1 to 5, the bracket 32 fixes the end 32 of the grill filler 16, the front end 45 of the fender panel 11, and the upper end of the bumper side member 21 to each other. That is, the front end mounting portion 50 of the fender panel 11 and the mounting end surface 35 of the grille filler 16 are superimposed on the first support portion 71 of the bracket 61 from the inside of the vehicle body in this order, and the bolt 81 is screwed into the weld nut 77, whereby It is screwed to the first support 71.

Since the inner diameter of the terminal mounting hole 36 of the grille filler 16 and the inner diameter of the front end mounting hole 51 of the fender panel 11 are each slightly larger than the outer diameter of the shaft of the bolt 81, each of the bolts 81 is mounted. By passing through the holes 36 and 51, the positions of the end 32 of the grille filler 16 and the front end 45 of the fender panel 11 with respect to the bracket 61 in the up-down direction and the front-back direction are determined.

That is, the mounting holes 36 and 51 are formed between the end 32 of the grille filler 16 and the front end 4 of the fender panel 11.
5 is used as a reference hole when assembling. First support part 7
1 can bend in the width direction of the vehicle body, so that the end 32 of the grille filler 16 and the front end 45 of the fender panel 11 can be bent.
Can be displaced to some extent in the width direction of the vehicle body even when it is fixed to the first support portion 71.

Further, the upper end mounting portion 25 of the bumper side member 21 is overlapped from the lower surface side of the second support portion 72 of the bracket 61, and the stepped bolt 83 is passed through the upper end mounting hole 27 of the bumper.
The bumper upper end mounting portion 25 is supported by the second support portion 72 by being screwed into the weld nut 78. The stepped bolt 83 has a columnar intermediate shaft portion 84 longer than the thickness of the bumper upper end mounting portion 25.

The inner diameter of the bumper upper end mounting hole 27 is larger than the outer diameter of the intermediate shaft portion 84 of the stepped bolt 83.
Even if the stepped bolt 83 is tightened to the weld nut 78,
A play is provided so that the bumper upper end mounting portion 25 can move in the horizontal direction by the difference between the inner diameter of the mounting hole 27 and the outer diameter of the intermediate shaft portion 84. Then, by tightening the stepped bolt 83 to the weld nut 78, the vertical position of the bumper upper end mounting portion 25 is determined.

The lower mounting piece 55 of the fender panel 11 is superimposed on the third support portion 73 of the bracket 61 from the outside of the vehicle body, and a bolt 86 is passed through the fender lower mounting hole 56 and screwed into the weld nut 79 to thereby mount the lower part. Piece 5
5 is fixed to the third support portion 73.

Terminal mounting portion 26 of bumper side member 21
Is mounted on the lower edge flange 52 of the fender panel 11 from below, and a screw 88 such as a tapping screw is screwed into the terminal mounting hole 2.
The end of the bumper 12 is assembled to the fender panel 11 by passing the bumper 12 through the connection hole 53 and the female screw part 54.

Next, a procedure for assembling the grille filler 16, the fender panel 11, the bumper 12, and the like using the bracket 61 will be described. In addition, bracket 6
1 is previously fixed to the bracket mounting wall 75 of the body frame 17 by fixing means such as welding.

First, the first support portion 71 of the bracket 61
Then, the front end mounting portion 50 of the fender panel 11 and the mounting end surface 35 of the grille filler 16 are overlapped, and both are fixed to the first support portion 71 by bolts 81. By doing so, the front end mounting portion 50 of the fender panel 11 and the grille filler 16
Are restricted in the front-rear direction and the vertical direction.

The mounting end surface 35 and the front end mounting portion 50 can be displaced left and right within a range in which the first support portion 71 can bend in the left and right directions. Therefore, there is flexibility in assembling each part, and furthermore, the fender panel 11 and the grille filler 16 are provided.
Can be accurately matched with the adjacent portion. For this reason, even when the adjacent portion between the fender panel 11 and the grill filler 16 is connected at the curved portions 33 and 46, it is possible to avoid the occurrence of a discontinuous step.

Next, the lower mounting piece 55 of the fender panel 11 is fixed to the third support portion 73 of the bracket 61 with a bolt 86, whereby the fender panel 11 is restrained in the left-right direction and the up-down direction. Since the fender lower mounting hole 56 through which the bolt 86 passes is a long hole that is large in the front-rear direction of the vehicle body, even if the positions of the lower mounting piece 55 and the third support portion 73 are relatively slightly shifted in the vehicle front-rear direction, it is desirable. Can be assembled without any problem.

Next, the upper end mounting portion 25 of the bumper side member 21 is fixed to the bracket 61 by the stepped bolt 83.
, The vertical position of the bumper side member 21 is determined. For this reason, the lower surface of the grille filler 16 and the lower surface of the fender panel 11 can be substantially flush with the upper surface of the bumper side member 21, and a discontinuous gap between them can be avoided. Moreover, since the second support portion 72 can be displaced to some extent in the width direction of the vehicle body in a range where the first support portion 71 can bend in the left-right direction, it is possible to provide flexibility in mounting the bumper side member 21.

Next, the terminal mounting portion 26 of the bumper side member 21 is placed on the lower edge flange 52 of the fender panel 11 and both are fixed by screws 88. Thereby, the position in the left-right direction and the position in the vertical direction between the terminal of the bumper side member 21 and the fender panel 11 are accurately determined. Moreover, since the terminal mounting holes 28 are long holes in the front-back direction,
Even if the position of the connection hole 53 or the terminal position of the bumper side member 21 is slightly shifted in the front-rear direction, it can be assembled without any problem.

The present invention can be applied to a front bumper having no bumper side member 21 or a front bumper made of synthetic resin. Further, grill filler 16 may be an integrally molded product of synthetic resin.

[0037]

According to the present invention, the adjacent portion between the grille filler and the fender panel can be accurately aligned, and the positional relationship with the bumper can be accurately regulated, so that a good appearance can be maintained. it can. In particular, when the grill filler and the fender panel are continuous in a curved shape around the round head lamp, the step of the adjacent portion between the grill filler and the fender panel is easily conspicuous. The grill filler, the fender panel, and the bumper can be assembled in a mutual relationship. Further, these can be assembled to each other by using a common bracket, and since the construction is flexible, the assembling work is easy.
