本发明公开了一种车身安全结构，包括：座椅支撑架，固定设置在地板上；座椅安装架，通过转轴与所述座椅支撑架可转动地连接；传力杆，设置在所述地板上，一端形成冲击块，朝向所述座椅安装架，在发生撞击时，所述传力杆受撞击移动，推抵所述座椅安装架沿所述转轴转动。本发明的车身安全结构，在车速较大时发生碰撞，大的撞击力通过传力杆传递，使座椅安装架转动，使座椅发生偏移，或者直接将座椅通过转动甩出驾驶舱外，以避免因驾驶舱溃缩带来的人员伤亡。

The invention discloses a vehicle body safety structure, which comprises: a seat support frame fixedly arranged on the floor; A seat mounting frame rotatably connected with the seat support frame through a rotating shaft; The dowel bar is arranged on the floor, one end forms an impact block and faces the seat mounting frame. In case of impact, the dowel bar is moved by impact and pushed against the seat mounting frame to rotate along the rotating shaft. The body safety structure of the invention collides when the vehicle speed is large, and the large impact force is transmitted through the dowel rod to rotate the seat mounting frame and offset the seat, or directly throw the seat out of the cockpit through rotation, so as to avoid personal injury and death caused by cockpit collapse.
