Abstract

본 발명은 자동차 양쪽 중심기둥(center pillar)이 위치되는 부위의 플로어(floor) 보강구조에 관한 것으로서, 중심기둥이 실내로 침입되는 것과 하단부의 회전 변형되려는 것을 효과적으로 억제시켜 주기 위해, 중심부에 전후방향으로 터널(11)이 상부로 돌출되게 형성되고 양측단부가 사이드실(40) 내측면에 연결되는 플로어판넬(10)의 상단면에 소정 간격을 두고 중간멤버(50)가 횡방향으로 설치되어, 상기 중간멤버(50)의 일단부가 사이드실(40)에 연결되는 중심기둥(41)의 내측면에 연결되고, 타단부가 터널(11)의 측면에 부착되도록 하여, 중간멤버(50)의 상부에 의자가 설치되도록 하며, 위자를 지지하는 중간멤버(50)가 중심기둥(41)을 지지하고 플로어판넬(10)과 터널(11)을 통해 외력이 폭넓게 분산되도록 하여, 측면 충돌과 같이 외부에서 중심기둥(41)부위에 충격하중이 절단되면, 중심기둥(41)의 하단부가 회전되려는 것과 실내로 침입하려는 것을 억제하도록 하는 자동차 플로어의 보강구조이다.The present invention relates to a floor reinforcement structure in a location where both center pillars of an automobile are located. In order to effectively suppress the intrusion of the center pillar into the interior and the rotational deformation of the lower end portion, the front and rear directions of the center pillar are effectively prevented. The intermediate member 50 is formed in the transverse direction at a predetermined interval on the upper end surface of the floor panel 10 in which the tunnel 11 protrudes upward and both side ends thereof are connected to the inner surface of the side seal 40. One end of the intermediate member 50 is connected to the inner surface of the central column 41 connected to the side chamber 40, and the other end is attached to the side of the tunnel 11, the upper portion of the intermediate member 50 The chair is installed in the upper part, and the middle member 50 supporting the upper arm supports the central column 41 and allows the external force to be widely distributed through the floor panel 10 and the tunnel 11 from the outside, such as a side collision. Fill the center column (41) When the load is cut, the reinforcing structure of the vehicle floor to be suppressed to as intrusion into the lower end of the center post 41, to become the rotation chamber.
