Description

자동차의 차체보강구조{CAR BODY REINFORCEMENT STRUCTURE OF VEHICLE}Car body reinforcement structure {CAR BODY REINFORCEMENT STRUCTURE OF VEHICLE}

본 발명은 자동차의 차체보강구조에 관한 것으로, 특히 주행중 정면충돌시 실내방향으로 밀려들어오는 전방차체의 변형량을 최소화시켜, 탑승자의 안전을 효과적으로 보호하도록 된 자동차의 차체보강구조에 관한 것이다.The present invention relates to a vehicle body reinforcement structure, and more particularly to a vehicle body reinforcement structure to effectively protect the safety of the occupant by minimizing the amount of deformation of the front vehicle body to be pushed in the room direction during a frontal collision during driving.

일반적으로, 차체의 전방쪽에 설치되면서 프런트윈도우와 연결되는 카울로워패널(1)의 일단에는 도 1과 도 2에 도시된 바와 같이 프런트필러인너패널(2)의 일측면 소정부위가 접합되고, 이 프런트필러인너패널(2)의 타측면에는 사이드아웃터패널(3)이 일정한 사이간격을 두고 접합되어 있다.In general, a predetermined portion of one side of the front pillar inner panel 2 is joined to one end of the cowl panel 1 connected to the front window while being installed at the front side of the vehicle body, as shown in FIGS. 1 and 2. The side outer panel 3 is joined to the other side of the front pillar inner panel 2 at a predetermined interval.

따라서, 주행중 정면충돌사고가 발생되면 충돌시 발생된 충격력은 엔진룸의 형상을 변형시키면서 도시된 화살표 L방향으로 이동되어 카울로워패널(1)로 전달되게 되고, 이 카울로워패널(1)과 프런트필러인너패널(2) 및 사이드아웃터패널(3)은 전달받은 충격력에 의해 그 형상이 변형되면서 충격력을 1차감소시키게 되며, 상기 프런트필러인너패널(2)과 사이드아웃터패널(3)을 통과하여 대시보드로 전달된 충격력은 대시보드의 형상을 변형시키면서 2차감소되게 된다.Therefore, if a frontal collision accident occurs while driving, the impact force generated during the collision is moved in the direction indicated by arrow L while changing the shape of the engine room and transmitted to the cowl panel 1, and the cowl panel 1 and the front Filler inner panel (2) and side outer panel (3) is deformed by the transmitted impact force to reduce the impact force primarily, through the front pillar inner panel (2) and side outer panel (3) The impact force transmitted to the dashboard is secondarily reduced while deforming the shape of the dashboard.

그러나, 상기와 같은 종래의 차체구조에 의하면, 상기 카울로워패널(1)과 프런트필러인너패널(2)의 접합부위가 개구된 단면의 구조로 이루어져 있기 때문에, 즉 상기 카울로워패널(1)의 전장에 비해 카울로워패널(1)과 프런트필러인너패널(2)의 접합부위가 한부위만 서로 접합되어 있기 때문에, 전방충돌사고 발생시 상기 카울로워패널(1)의 변형량이 커지면서 프런트필러인너패널(2)과 사이드아웃터패널(3)의 변형량도 커지게 되어 충격력을 효과적으로 감소시키지 못하게 될 뿐만 아 니라, 이에따라 대시보드로 전달되는 충격력도 커지게 되어 대시보드의 변형량이 커짐으로서 탑승자의 안전이 효과적으로 보호되지 못하는 문제점이 있었다.However, according to the conventional vehicle body structure as described above, since the joint portion of the cowl panel 1 and the front pillar inner panel 2 has an open cross-sectional structure, that is, the cowl panel 1 Compared to the overall length, since only the one joint portion of the cowl panel 1 and the front pillar inner panel 2 is joined to each other, the front pillar inner panel 2 increases as the deformation amount of the cowl panel 1 increases in the event of a frontal collision. ) And the side outer panel (3) also increases the amount of deformation not only to effectively reduce the impact force, but also increases the impact force delivered to the dashboard, thereby increasing the amount of deformation of the dashboard to effectively protect the occupant's safety. There was a problem.

이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 카울로워패널과 프런트필러인너패널의 소정부위를 보강패널부재에 의해 서로 연결되게 결합시켜서 접합부위의 단면구조를 폐단면이 되게 함으로써, 전방충돌사고 발생시 상기 보강패널부재에 의해 카울로워패널 및 프런트필러인너패널과 사이드아웃터패널의 변형량을 최소화시켜 충격력을 효과적으로 감소시키면서 대시보드의 변형량도 최소화시켜 탑승자의 안전을 효과적으로 보호하도록 된 자동차의 차체보강구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by coupling the predetermined portion of the cowl panel and the front filler inner panel to be connected to each other by a reinforcing panel member to make the cross-sectional structure of the joint portion to a closed cross-section, In the case of a frontal collision, the body of the automobile is designed to effectively protect the safety of the occupants by minimizing the deformation of the cowl panel, the front pillar inner panel and the side outer panel by effectively reducing the impact force while minimizing the deformation of the dashboard. The purpose is to provide a reinforcing structure.
