본 발명은 자동차의 센터필러(CENTER PILLAR)구조에 관한 것으로, 더 상세하게는 자동차의 측면 충돌시 센터아웃터패널(CENTER OUTER PANEL)의 전방부에서 충분한 충격흡수를 수행할 수 있도록 하며, 후방부의 센터인너패널(CENTER INNER PANEL)과의 결합강성을 증대시켜 실내의 승객에 전달되는 충격량을 최대한 줄일 수 있도록 한 센터필러구조에 관한 것이다.The present invention relates to a center pillar structure of a vehicle, and more particularly, to sufficiently absorb shock at the front of the center outer panel in the event of a side collision of the vehicle, and to the center of the rear portion. The present invention relates to a center pillar structure that increases the coupling rigidity with the inner panel to minimize the amount of impact transmitted to passengers in the room.
일반적으로 자동차의 충돌사고시 승객의 안전을 확보하기 위한 테스트로는 전방충돌(FRONT IMPACT)과 측면충돌(SIDE IMPACT)이 있으며, 이는 자동차의 안전성을 확보하는 중요한 요소로서 이미 각 나라에서는 이러한 충돌시의 안전치를 법규화하여 수입규제등의 큰 항목으로 이용되고 있다.In general, the tests to ensure the safety of passengers in the event of a car crash include FRONT IMPACT and SIDE IMPACT, which are important factors to ensure the safety of the car. It is used as a large item such as import regulation by legalizing safety value.
그러나 현재 생산되고 있는 자동차는 대부분 전방충돌에 대한 안전치는 어느정도 확보하고 있으나, 측면충돌에 대한 안전치는 미흡한 실정이다.However, most of the cars currently produced have a certain level of safety against forward collisions, but the safety against side collisions is insufficient.
즉 그 원인으로는 제1도에 도시한 바와같이 센터필러(10)의 구조가 취약하기 때문이며, 실제로 타차량과의 측면충돌시 외부로부터 이중충돌벽(MOVING DEFORMABLE BARRIER ; 통상 MDB라 약칭함)이 충돌해 왔을때의 시험조건을 적용할 경우 센터필러(10)부분이 실내로 밀리면서 사이드실도어, 루프상단까지 변형이 오고, 이로 인하여 승객 인체의 상해치중 골반부에 해당하는 펠비스(PELVIS)값이 커지는 문제가 있다.This is because the structure of the center pillar 10 is weak as shown in FIG. 1, and in fact, a double collision wall (MOVING DEFORMABLE BARRIER; commonly abbreviated as MDB) from the outside when the side collision with another vehicle occurs. In case of applying the test condition when the collision occurs, the center pillar 10 is pushed into the room, and the side seal door and the roof top are deformed, which causes the PELVIS value corresponding to the pelvis of the injured body of the passenger. There is a growing problem.
제2도는 종래의 센터필러박스(CENTER PILLAR BOX;10)의 구조를 나타낸 조립단면도로서, 센터아웃터패널(3)과 센터인너패널(2)이 보강부재(4)를 사이에 두고 마주 결합되어 센터필러박스(10)를 구성한다.2 is an assembly cross-sectional view showing the structure of a conventional center pillar box (CENTER PILLAR BOX; 10), the center outer panel (3) and the center inner panel (2) is opposed to each other with the reinforcing member (4) between the center The pillar box 10 is constituted.
따라서 이와같이 구성된 종래의 센터필러구조는, 상술한 바와 같이 센터아웃터패널(3)과 센터인너패널(2)이 마주 결합된 단순구조로 되어 매우 취약하기 때문에 차량의 측면 충돌시 센터필러박스(10)의 센터아웃터패널(3)에서 충분한 흡수가 되지않고 또한 후방의 센터인너패널(2)과의 결합강성이 유지되지 않기 때문에 이로 인하여 상기 각각의 부품들이 실내로 밀리게 되어 사이드실 도어, 루프상단까지 변형이 초래되어 인체상해 중 특히 골반부에 해당하는 펠비스값이 좋지 않은 문제가 있었다.Therefore, the conventional center pillar structure configured as described above has a simple structure in which the center outer panel 3 and the center inner panel 2 face each other as described above, and thus are very fragile. Because of insufficient absorption in the center outer panel (3) of the center and the coupling rigidity with the center inner panel (2) of the rear is not maintained, this causes each of the parts to be pushed into the room to the side seal door, roof top Deformation is caused, there is a problem that the Pelvis value corresponding to the pelvic part, especially of the human injury is not good.
