The invention relates to the technical field of new energy vehicles, and discloses a bottom plate structure of a box chassis, the box chassis, a battery pack and a vehicle. The bottom plate structure of the box chassis comprises a bottom plate (10), two first cross beams (11) and at least one second cross beam (12), and the first cross beams and the second cross beams are attached to the front face of the bottom plate; the bottom plate comprises two first edges and two second edges which are perpendicular to each other, the first cross beam is parallel to the first edges and extends from one second edge to the other second edge, and the second cross beam is parallel to the second edges and extends from one first edge to the other first edge. The two first cross beams are arranged close to the two first edges respectively, gaps are formed between the two first cross beams and the first edges, gaps are formed between the two ends of the first cross beams and the two second edges, and gaps are formed between the two ends of the second cross beams and the two first edges. According to the bottom plate structure of the box body chassis, the production efficiency of the battery pack can be improved, and the production cost is reduced.

    本发明涉及新能源汽车技术领域,公开了一种箱体底盘的底板结构、箱体底盘、电池包和汽车,箱体底盘的底板结构包括底板(10)、两个第一横梁(11)和至少一个第二横梁(12),第一横梁和第二横梁贴合设置在底板的正面,底板包括彼此垂直的两个第一边和两个第二边,第一横梁平行于第一边且从一个第二边延伸至另一个第二边,第二横梁平行于第二边且从一个第一边延伸至另一个第一边,其中,两个第一横梁分别靠近两个第一边设置且和第一边之间具有间隙,第一横梁的两端和两个第二边之间具有间隙,多个第二横梁的两端和两个第一边之间具有间隙。本申请提供的箱体底盘的底板结构能够提高电池包的生产效率,降低生产成本。
