Description

차량의 후방차체 보강구조{Rear Body Reinforcement Structure of Vehicles}Rear Body Reinforcement Structure of Vehicles

본 발명은 차량의 후방 차체를 보강시킨 구조에 관한 것으로, 특히 차량의 후방충돌 또는 추돌시 차체에 가해지는 충격에너지로부터 연료탱크와 같은 부품들의 접촉정도를 감소시킨 차량의 후방차체 보강구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure that reinforces a rear body of a vehicle, and more particularly, to a rear body reinforcement structure of a vehicle that reduces the contact degree of components such as fuel tanks from the impact energy applied to the vehicle body during a rear collision or a collision of the vehicle. .

일반적으로 차량의 후방충돌은 그 대부분(약 70%정도)이 후방의 백판넬과 범퍼에 편향 충돌되는 오프셋(OFFSET)충돌로 이루어지고 있는바, 이러한 후방 오프셋충돌은 충돌시 차체에 가해지는 충돌에너지가 리어 엔드판넬과 리어플로어의 한쪽방향으로 편향되어 전달됨에 따라 차체에 설치되는 연료탱크와 같은 부품파손에 상당한 악영향을 끼치게 된다.In general, the rear collision of the vehicle is composed of offset collisions in which most of the rear collisions (about 70%) are deflected and collided with the rear panel and the bumper. As it is deflected and transmitted in one direction of the rear end panel and the rear floor, there is a significant adverse effect on the damage of parts such as fuel tanks installed in the vehicle body.

즉 종래 차량의 후방충돌시 도 2에 도시된 바와 같이 리어 범퍼스테이(101)가 연결되는 리어 사이드부재(102)를 가로질러 크로스부재(103)가 설치되는 구조로 되어 있기 때문에, 충격에너지는 상기 리어 범퍼스테이(101)와 리어 사이드부재(102)를 통하여 편향 전달됨에 따라 차체 변형과 부품손상, 특히 연료탱크가 리어플로어의 접촉되어 심하게 변형되는 문제점이 있었다.That is, since the cross member 103 is installed across the rear side member 102 to which the rear bumper stay 101 is connected as shown in FIG. As the deflection is transmitted through the rear bumper stay 101 and the rear side member 102, there is a problem in that the vehicle body deformation and component damage, in particular, the fuel tank is severely deformed due to contact of the rear floor.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 차량의 후방 오프셋 충돌시 리어 사이드부재 쪽에 가해지는 충격에너지에 효과적으로 대응하여 연료탱크와 같은 부품의 변형과 차체의 변형을 최소화시킨 차량의 후방차체 보강구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, and the vehicle minimizes the deformation of the components such as fuel tank and the deformation of the vehicle body by effectively responding to the impact energy applied to the rear side member during the rear offset collision of the vehicle. Its purpose is to provide a rear body reinforcement structure.

도 1은 본 발명에 따른 차량의 후방차체 보강구조를 나타낸 부분 분리사시도,1 is a partially separated perspective view showing a rear body reinforcement structure of a vehicle according to the present invention;

도 2는 종래구조로서, 도 1에 대응되는 사시도이다.2 is a perspective view corresponding to FIG. 1 as a conventional structure.

1 : 리어 범퍼스테이2 : 리어 사이드부재1: Rear bumper stay 2: Rear side member

3 : 크로스부재4 : 제 1보강부재3: cross member 4: first reinforcing member

5 : 제 2보강부재5: second reinforcing member

상기와 같은 목적을 달성하기 위한 본 발명은 리어 범퍼스테이가 연결설치되는 리어 사이드부재를 가로질러 크로스부재가 설치되어 이루어진 차량의 후부차체 구조에 있어서, 상기 리어 사이드부재와 크로스부재의 연결부위에 제 1보강부재를 연결부착 시키며, 상기 리어 사이드부재와 리어 범퍼스테이 사이에도 제 2보강부재를 부착시킨 구조로 되어 있다.In order to achieve the above object, the present invention provides a rear body structure of a vehicle in which a cross member is installed across a rear side member to which a rear bumper stay is connected, and is provided at a connection portion of the rear side member and a cross member. A reinforcing member is attached and attached, and a second reinforcing member is attached between the rear side member and the rear bumper stay.

이하 본 발명을 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 차량의 후방차체 보강구조를 나타낸 부분 분리사시도이다.1 is a partially separated perspective view showing a rear body reinforcement structure of a vehicle according to the present invention.

본 발명은 리어 범퍼스테이(1)가 연결 설치되는 리어 사이드부재(2)를 가로질러 크로스부재(3)가 설치되어 이루어진 차량의 후부차체 구조에 있어서, 상기 리어 사이드부재(2)와 크로스부재(3)의 연결부위에 제 1보강부재(4)를 연결부착 시키며, 상기 리어 사이드부재(2)와 리어 범퍼스테이(1)사이에도 제 2보강부재(5)를 부착시킨 구조로 되어 있다.According to the present invention, in the rear body structure of a vehicle in which a cross member 3 is provided across a rear side member 2 to which a rear bumper stay 1 is connected, the rear side member 2 and a cross member ( The first reinforcing member 4 is attached to the connecting portion of 3), and the second reinforcing member 5 is also attached between the rear side member 2 and the rear bumper stay 1.

여기서 상기 제 1,2 보강부재(4,5)는 한쪽 리어 사이드부재(2)뿐만 아니라 대향된 다른쪽 리어 사이드부재(도면에는 도시하지 않았음)에도 동일하게 적용됨은 물론이다.Here, the first and second reinforcing members 4 and 5 are equally applied not only to one rear side member 2 but also to the opposite rear side member (not shown in the drawing).

따라서 상기 제 1,2 보강부재(4,5)는 리어 사이드부재(2)와 이에 각각 연결되는 리어 범퍼스테이(1)및 크로스부재(3)의 연결부위를 보다 강화시킨 구조로 덧붙혀 장착되어 있기 때문에 차량의 후방충돌시 가해지는 충격하중으로부터 차체와 리어플로어의 변형량을 감소시킬 수 있음에 따라 연료탱크의 변형을 최소화시킨다.Therefore, the first and second reinforcing members 4 and 5 are attached to the rear side member 2 and the rear bumper stay 1 and the cross member 3 connected to each other in a reinforced structure. Therefore, the deformation of the body and the rear floor can be reduced from the impact load applied during the rear collision of the vehicle, thereby minimizing the deformation of the fuel tank.

상기와 같이 본 발명에 따른 차량의 후방차체 보강구조는 리어 사이드부제의 강성을 보강시키어 후방 충돌시 연료탱크와 리어플로어의 접촉정도를 감소시킴에 따라 차체와 연료탱크의 변형을 최소화시킨 잇점이 있다.As described above, the rear body reinforcement structure of the vehicle according to the present invention has the advantage of minimizing the deformation of the vehicle body and the fuel tank by reducing the contact between the fuel tank and the rear floor during rear collision by reinforcing the rigidity of the rear side attachment. .
