Abstract

본 발명은 리어 프레임의 형상을 변경하여 좌우의 리어 프레임의 전단부 간격을 좁게 함으로써, 리어 프레임과 사이드 실 사이에 간격이 생기게 하여, 자동차 측면 하단의 차체 구조에 있어 폐단면을 확대함으로써, 후면 및 측면 충돌 성능이 향상되는 차체 구조에 관한 것이다. 본 발명의 차체 구조는 리어 프레임(21) 하단과 사이드실 내측 패널(11) 하단을 연잇는 스티프너(25)를 포함한다. 한편 본 발명에 의한 리어 프레임(21)은 좌우 방향으로는 굴절되어 있지 않아서 차량 좌측 및 우측의 리어 프레임(21)의 전단수평부(21a)간 간격은 후단수평부(21c) 간격과 동일하다. 이에 따라 후면 및 측면 충돌에 대한 강성이 크게 향상됨과 아울러, 차체의 강성이 높아짐에 따라 소음과 진동이 줄어들고 승차감이 향상되는 효과도 수반된다.The present invention changes the shape of the rear frame to narrow the space between the front and rear ends of the left and right rear frames, thereby creating a gap between the rear frame and the side seals, thereby enlarging the closed section in the vehicle body structure at the lower side of the vehicle, The present invention relates to a body structure in which side impact performance is improved. The vehicle body structure of the present invention includes a stiffener 25 connecting the lower end of the rear frame 21 and the lower end of the side seal inner panel 11. On the other hand, the rear frame 21 according to the present invention is not refracted in the left-right direction, so that the distance between the front horizontal portion 21a of the rear frame 21 on the left and right sides of the vehicle is equal to the rear horizontal portion 21c. Accordingly, the rigidity of the rear and side collision is greatly improved, and as the rigidity of the vehicle body is increased, the noise and vibration are reduced and the riding comfort is improved.
