TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mounting structure of a grill filler panel disposed between left and right fender panels provided at a front portion of a vehicle body of an automobile and an upper surface of a front bumper.
[0002]
[Prior art]
As is well known, four parts, such as the left and right fender panels, the front bumper on the lower surface, and the radiator grill and the like on the upper surface are arranged on the left and right sides of the grill filler panel of the automobile.
The grille filler panel and the four components are fixed to the vehicle body via a bracket or the like welded to a front portion of the vehicle body of the vehicle. -164871.
[0003]
In the technique described in Japanese Patent Application Laid-Open No. H8-164871, the bottom of a bracket formed in a U-shape on the left and right of the front part of the vehicle body is welded to the vehicle body side so as to extend in the vertical direction of the vehicle body.
The bracket includes a first support portion protruding forward of the vehicle body from one side edge of the bottom portion extending in a vertical direction of the vehicle body, and a vehicle body of the vehicle body from a lower edge of the first support portion. A second support portion extending horizontally in the width direction, and a third support portion projecting from the other side edge of the bracket to the front of the vehicle body and provided in parallel with the first support portion. It is configured.
[0004]
Further, a grill filler panel is disposed between the radiator grill provided at the front of the vehicle body and the front bumper so as to be elongated between the left and right fenders.
A grill filler mounting end surface having a side surface bent rearward of the vehicle body from the front surface of both ends in the vehicle width direction of the grill filler panel is disposed so as to overlap with the first support member in the vehicle width direction. Further, the fender mounting end face bent from the front surface of the front end of the fender panel to the rear of the vehicle body and provided so as to extend in parallel with the grille filler mounting end face is formed by combining the above-described first support member and the grille filler mounting end face with each other. It is arranged so as to be inserted in between, and the three members are overlapped in the vehicle width direction, and screwed to a weld nut provided on the first support member with a bolt from the vehicle width direction. It is to be concluded.
[0005]
An elongated hole extending in the front-rear direction of the vehicle body is provided in a lower mounting piece extending downward from a front portion of the fender panel, and is fixed to a third support member of the bracket by a bolt.
Also, the inner diameter of the mounting hole of the upper mounting portion of the bumper is formed to be larger than the outer diameter of the stepped bolt, and the upper mounting portion is overlapped by the second support member in the vertical direction of the vehicle body to form the stepped portion. It is configured so that it can be fastened by adjusting the position in the horizontal direction with bolts.
[0006]
[Problems to be solved by the invention]
However, as described above, since the grill filler mounting end face and the fender panel mounting end face only extend in the front-rear direction of the vehicle body, the positioning is not determined, and the mounting positional relationship in the vehicle body front-rear direction is managed. This is difficult, and a gap or a step may occur when the positions of the grill filler panel and the fender panel are shifted in the front-rear direction at the adjacent portion.
[0007]
Furthermore, since the front end of the fender panel and both ends of the grille filler panel are constituted by, for example, arcuate curved lines following the contours of a round or elliptical headlamp, the grille filler panel and the fender are arranged at the curved lines. If a position shift occurs in a portion adjacent to the panel, the above-described line becomes discontinuous, and the design appearance around the grill filler panel is significantly reduced, which may reduce the value as a product.
[0008]
In addition, as described above, before the coating, the grill filler panel mounting end face, the fender panel mounting end face, and the first support member are overlapped and fastened and fixed by bolts. However, since the gap between each of the grille filler panel mounting end face, the fender panel mounting end face, and the first support member is extremely small, there is a portion where the paint for the electrodeposition coating cannot enter and is not coated.
[0009]
If the vehicle is used in this state, rust is generated from a portion where the paint does not adhere, and the rust may come out to the front side and impair the aesthetic appearance.
In the above-mentioned conventional mounting structure, there is a possibility that rust may be generated at the above-mentioned portion. To prevent this, rust-proof steel plates are used, but the cost is high.
Further, the workability for arranging the three members of the grill filler panel mounting end face, the fender panel mounting end face, and the first support member and tightening the bolts is very inefficient.
[0010]
That is, after the side surface of the first support member of the bracket attached to the lower part of the headlamp at the vehicle interior side and the grille filler panel mounting end surface are overlapped, the front end is the vehicle body. In order to insert and mount the fender panel having the fender panel mounting end face bent rearward between the grille filler panel mounting end face and the first support member, the fender panel must go over the first support member and be brought down. The assembly work must be performed between the end face of the grille filler panel and the first support member, and this assembling operation is very difficult, requiring man-hours and manpower to automate this assembling line. Also in this case, a sensor or a complicated structure is required, and the cost is increased.
[0011]
The present invention has been made in view of these problems, and in a mounting structure of a grill filler panel disposed between left and right fender panels provided at a front portion of a vehicle body of an automobile, the left and right fender panels face each other. A fender panel mounting flange that is bent from the front end and extends inward in the vehicle width direction from the rear of the folded surface that extends rearward of the vehicle, and a mounting surface that overlaps the fender panel mounting flange. A grill filler panel bracket which is joined to left and right ends of the grill filler panel is provided, and a mounting surface of the grill filler bracket and the fender panel mounting flange are overlapped and mounted on the vehicle body by the mounting means, Provided is a grill filler panel mounting structure that prevents the generation of rust from a mounting portion and facilitates the above assembling work. For the purpose of theft.
