In order to achieve the optimum depth of the pit, the thickness of the entire car floor must be reduced. The traditional car floor adopts a layered and superimposed structure of upper car floor 100, anti-vibration rubber, and car floor frame 200, resulting in a relatively large thickness of the car floor. , affecting the pit depth. In this embodiment, a "C" shaped side beam with a smaller upper bending edge is adopted, so that the anti-vibration rubber of the car bottom and the upper car bottom 100 can avoid the bending part 213 with a smaller bending edge on the side beam, so that The anti-vibration rubber of the car bottom and the upper car bottom 100 are embedded to form an embedded car bottom. Compared with the traditional car bottom structure, this form is conducive to reducing the thickness of the car bottom, thereby further reducing the depth of the pit. Because the main function of the beam body is bending resistance, the bending resistance part 213 on the "C" beam body can greatly increase the bending resistance section coefficient of the beam body without increasing the thickness of the plate, which has a great impact on the overall weight and cost The way to improve the bending interface coefficient.
