Description

차량용 리어범퍼 설치구조Vehicle Rear Bumper Installation Structure

본 발명은 차량용 리어범퍼 설치구조에 관한 것으로서, 특히 차체의 앤드멤버에 설치되는 리어범퍼에 다수의 고정플랜지를 형성하고, 각 플랜지에는 보강부재에 형성한 플랜지와 차체에 구비된 범퍼레인프 연결브라켓과 대응시켜 파스트너로 고정시키며, 보강부재는 앤드멤버와 용접고정시킴에 따라 리어범퍼의 견고성을 높일 수 있게 한 차량용 리어범퍼 설치구조에 관한 것이다.The present invention relates to a rear bumper mounting structure for a vehicle, and in particular, a plurality of fixing flanges are formed on a rear bumper installed in an end member of a vehicle body, and each flange includes a flange formed on a reinforcing member and a bumper lane connection bracket provided on the vehicle body. The fastener is fastened in correspondence with the reinforcing member, and the reinforcing member is related to the rear bumper mounting structure for the vehicle, which is capable of increasing the rigidity of the rear bumper by welding the end member.

일반적으로 차량의 리어범퍼는 차체의 후방 앤드멤버에 설치하여 차체를 보호하고, 충돌시 충격을 흡수할 수 있게 한 것이다.In general, the rear bumper of the vehicle is installed in the rear end member of the vehicle body to protect the vehicle body and to absorb shocks during a collision.

이와같은 종래의 구조를 설명하면 도 5에서 보는 바와같이 차체의 후방 앤드멤버(EM)의 상부에 트렁크리드(TR)가 구비되고, 앤드멤버(EM)의 후방에는 리테이너(RT)가 구비되며, 리테이너(RT)의 후방과 상부에는 리어범퍼(1)가 파스트너(10)로 고정설치되었다.Referring to the conventional structure, as shown in FIG. 5, the trunk lid TR is provided at an upper portion of the rear end member EM of the vehicle body, and a retainer RT is provided at the rear of the end member EM. The rear bumper 1 was fixed to the rear fastener 10 by the fastener 10.

이러한 리어범퍼(1)는 차체에 별도의 지지구가 배제된 상태로 리어범퍼(1)가 리테이너(RT)에 의해 파스트너(10)로 고정설치됨에 따라 충돌시 리테이너(RT)가 앤드멤버(EM)에 접촉하여 앤드멤버(EM)와 차체가 파손되는 폐단이 있었다.Since the rear bumper 1 is fixed to the fastener 10 by the retainer RT in a state in which a separate support is excluded from the vehicle body, the rear bumper 1 has an end member (RT) at the time of collision. There was a closed end in which the end member (EM) and the car body were damaged in contact with EM).

또한 상기 리어범퍼(1)의 다른 제1실시예에 있어서는 상부에 트링크리드(T)가 구비된 앤드멤버(EM)의 상부를 후방측으로 하향 경사지게 형성하고, 상기 앤드멤버(EM) 의 경사면 상부에 리어범퍼(1)를 스크류(SC)와 그로메트(GR)를 이용하여 체결고정시킨 것이다.In addition, in another first embodiment of the rear bumper 1, the upper part of the end member EM having the link lead T is formed to be inclined downward toward the rear side, and the upper part of the inclined surface of the end member EM. The rear bumper (1) is fastened using screws (SC) and grommet (GR).

이러한 리어범퍼(1)는 앤드멤버(EM)에 직접 체결고정되어 있어 지지결합견고성이 매우 취약하여 충돌시의 파손이 심하였고, 스크류(SC)가 리어범퍼(1)의 외부에 노출되어 외적미감을 저하시키는 폐단이 있다.Since the rear bumper 1 is directly fastened and fixed to the end member EM, it is very vulnerable in the strength of the support coupling, so that it is severely damaged during the collision, and the screw (SC) is exposed to the outside of the rear bumper 1 so that the external aesthetics are sensed. There is a closed end that lowers.

또한 리어범퍼(1)의 다른 제2실시예에 있어서는 앤드멤버(EM)의 내측에 트링크 트림패널(TP)이 구비되고, 앤드멤버(EM)의 후방에는 리어범퍼(1)를 볼트(B)와 너트(N)로 고정시킨 것이다.In another second embodiment of the rear bumper 1, the trim trim panel TP is provided inside the end member EM, and the rear bumper 1 is bolted to the rear of the end member EM. ) And nuts (N).

이러한 리어범퍼(1)는 앤드패널(EM)의 내부에서 공구를 이용하여 리어범퍼(1)에 볼트(B)와 너트(N) 체결에 의해 리어범퍼(1)를 고정시킴에 따라 트림패널(TP)의 간섭으로 이를 제거시킨다음 작업을 시행하므로서, 분해작업성이 용이하지 못하였고, 리어범퍼(1)가 앤드멤버(EM)에 직접 설치되어 있어 충돌시 견고성을 높일 수 있는 문제점이 있었다.The rear bumper 1 fixes the rear bumper 1 by fastening the bolt B and the nut N to the rear bumper 1 by using a tool inside the end panel EM. TP) by removing the interference by the operation, it was not easy to disassemble work, there was a problem that the rear bumper (1) is installed directly in the end member (EM) to increase the robustness in the collision.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 발명한 것으로서, 차체의 앤드멤버에 설치되는 리어범퍼에 다수의 고정플랜지를 형성하고, 각 플랜지에는 보강부재에 형성한 플랜지와 차체에 구비된 범퍼레인프 연결브라켓과 대응시켜 파스트너로 고정시키며, 보강부재는 앤드멤버와 용접고정시킴에 따라 리어범퍼의 조립견고성을 높이고, 충돌시 차체의 손상을 방지할 수 있게 한 것을 목적으로 한다.The present invention is invented to solve the above conventional problems, a plurality of fixing flanges are formed on the rear bumper installed in the end member of the vehicle body, each flange formed on the reinforcing member and the bumper provided on the vehicle body It is designed to be fastened with fasteners in correspondence with the rain connection bracket, and the reinforcing member is welded with the end member to increase the assembly rigidity of the rear bumper and to prevent damage to the vehicle body in the event of a collision.
