Description

Structure for rear quarter panel {Structure for Rear Quarter Panel}

The present invention relates to a rear quarter panel fastening structure, provides a shock absorber bracket which is fastened to the outside of the wheel house and has a reinforcement integrally positioned to provide a shock absorber, and a package in which the shock absorber bracket is located inside the wheel house. Since it provides a fastening structure with a side assembly, it is a technology related to a new concept rear quarter panel fastening structure in which the number of parts is reduced and rigidity is maintained.

Generally, a vehicle is largely divided into a body and a chassis. The body is the part that forms the exterior of the car, and the chassis is the part that has the minimum amount of machinery necessary for the vehicle to run.

Fillers for supporting the front door and the rear door, forming the overall shape of the vehicle body, and maintaining side rigidity of the vehicle body are fastened to the outer portions of the front door and the rear door disposed on both sides of the vehicle body.

The above-described filler is inclined at a predetermined angle toward the front of the vehicle body so as to support the front door while being in contact with the rear end of the engine compartment in front of the vehicle body, and is disposed between the front pillar, the front door and the rear door. Arranged in the vertical direction to support the front door and the rear door, the center pillar supporting the side of the vehicle body opened by the door and the rear end of the rear door coupled to the rear end are composed of the rear pillar supporting the rear door and the rear body.

In general, these fillers are arranged to increase the structural rigidity of the entire vehicle body by forming an annular structure in combination with a roof rail coupled to the ceiling portion of the vehicle body and a floor cross member coupled to the bottom portion of the vehicle body.

As shown in Fig. 1, the wheelhouse panel and the rear floor connection structure of a conventional vehicle have a rear floor 1 formed on the rear side of the vehicle and have shock absorber brackets 3 on both sides thereof. The panel 2 is joined, and the rear floor cross member 4 and the wheel house cover 6 are coupled to the rear floor 1 and the wheel house panel 2, respectively.

1, the rear floor cross member 4 and the wheel house cover 6 are connected to each other by a connecting member 5, and the rear to form an annular structure of the rear pillar portion of the vehicle. The floor cross member 4, the connecting member 5 and the wheel house cover 6 are arranged in a straight line.

However, as shown in FIG. 1, the rear floor cross member 4, the connecting member 5, and the wheel house cover 6 connected in a straight line have a shock absorber bracket 3 due to space constraints due to the layout of the rear of the vehicle body. And spaced apart from each other, which acts as a cause of weakening the rigidity of the connecting parts of the wheel house panel 2 and the rear floor 1.

That is, the reinforcement of the shock absorber bracket 3, which is a load input part, is insufficient due to the phase difference between the rear floor cross member 4, the connecting member 5, and the wheel house cover 6 and the shock absorber bracket 3 forming an annular shape. Therefore, there is a problem in that the durability of the input point is weak and the stiffness of the input point of the connecting portion of the wheel house panel 2 and the rear floor 1 is weak.

In addition, in order to improve the above problems, when the thickness of the connecting member or the like is increased or a separate reinforcing member is combined, there is a problem in that production cost and body weight increase.
