The coupling structure of the rear pillar part which added the member (cross member) is related.
스포츠유틸리티 차량(sports utility vehicles, SUV)이란 평상시엔 출퇴근용의 운송수단으로 사용되다가 주말엔 가족들과 야외에 나가 한적한 시간을 보내기에 유용한 레저용 자동차로서, 특히 험로 주행성능 및 구동력이 우수한 자동차를 말한다.A sports utility vehicle (SUV) is a recreational vehicle that is used as a commuter vehicle for daily commute, but it is useful to spend a quiet time outside with the family on weekends. Say.
이러한 스포츠유틸리티 차량의 경우 승용차의 트렁크 공간에 해당되는 러기지룸(luggage room)이 2열 시트 바로 뒤의 차량 후방에 마련되어 있고, 이 러기지룸의 양 측면에는 사이드글라스가 구비된다. 러기지 룸의 사이드글라스는 개폐 가능한 것도 있지만, 통상적으로 여닫을 수 없도록 고정된 픽스드 글라스(fixed glass)가 주류를 이룬다.In the case of such a sports utility vehicle, a luggage room corresponding to a trunk space of a passenger car is provided at the rear of the vehicle immediately behind the second row seats, and side glass is provided on both sides of the luggage room. The side glass of the luggage room can be opened and closed, but usually fixed glass is fixed so that it cannot be opened or closed.
이렇게 사이드글라스가 구비된 차량의 후방은 도1에 도시된 바와 같이 그 사이드글라스(1)가 장착된 공간으로 인하여 리어 필라부가 두 개로 나뉘는데, 상기 사이드글라스(1)의 전방에 있는 기둥을 C필라(C pillar)(2)라고 하고, 그 후방에 있는 기둥을 D필라(D pillar)(3)라고 한다.As shown in FIG. 1, the rear of the vehicle equipped with the side glass is divided into two rear pillars due to the space in which the side glass 1 is mounted. The pillar in front of the side glass 1 is a C-pillar. It is called (C pillar) (2), and the pillar in the back is called D pillar (3).
상기 C필라(2)와 D필라(3)는 사이드글라스(1)가 장착될 공간을 확보함과 동시에 차량의 루프부를 지지하도록 그 상부가 루프사이드멤버(4)와 연결된다.The C-pillar 2 and the D-pillar 3 are connected to an upper portion of the roof side member 4 so as to secure a space in which the side glass 1 is to be mounted and to support a roof portion of the vehicle.
따라서, C필라(2)와 D필라(3)가 이루는 골격구조는 전체적으로 "??"자 형상을 띠게 된다.Therefore, the skeletal structure formed by the C pillar 2 and the D pillar 3 has an overall "??" shape.
그러나 상기와 같은 종래의 리어필라부 결합구조는 C필라와 D필라의 하부가 서로 연결되어 있지 않아서 차체 후방에 가해지는 하중에 매우 취약한 구조를 보이고 있다. 따라서, 지속적으로 차체 후방에 가해지는 비틀림 진동에 의하여 차체 후방에 변형이 발생하고 후방 추돌사고시에도 러기지 룸이 급격히 찌그러지는 등의 문제점이 발생한다.However, the conventional rear pillar coupling structure as described above is very weak to the load applied to the rear of the vehicle since the lower portion of the C pillar and the D pillar is not connected to each other. Therefore, a problem occurs such that deformation occurs at the rear of the vehicle body due to the torsional vibration continuously applied to the rear of the vehicle body, and the luggage room is suddenly distorted even in the rear collision accident.
본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 제안된 것으로서, 그 목적은 차량의 리어 필라부를 형성하고 있는 C필라와 D필라의 결합구조를 개선하여 C필라와 D필라의 결합강성을 증대시키는데 있다.The present invention has been proposed to solve the above problems, and an object thereof is to improve the coupling structure of the C-pillar and the D-pillar forming the rear pillar part of the vehicle, thereby increasing the coupling stiffness of the C-pillar and the D-pillar. .
