The invention discloses a vehicle body chassis and an electric vehicle, and belongs to the technical field of vehicle body structures. The vehicle body chassis comprises a chassis body and a plurality of battery components. The chassis body comprises a pair of first longitudinal beams, a pair of second longitudinal beams, a first cross beam and a second cross beam. The pair of second longitudinal beams are arranged on the two sides of the pair of first longitudinal beams, the first cross beams are connected with the same ends of the first longitudinal beams and the second longitudinal beams, and the second cross beams are connected with the other ends of the first longitudinal beams and the second longitudinal beams. The first cross beam, the second cross beam and the pair of first longitudinal beams enclose to form an assembly area, and the first cross beam, the second cross beam, the first longitudinal beams and the second longitudinal beams enclose to form a buffer area. And the plurality of battery components are distributed in the assembly area. The multiple battery components are distributed on the assembly area formed on the chassis body, the whole vehicle height space occupied by the battery components is released, and the space utilization rate of a passenger compartment is increased. The space of the chassis body is large, the battery components are distributed in the assembly area, and the specific energy of the battery space is improved.

    本申请公开了一种车身底盘及电动汽车,属于车身结构技术领域。所述车身底盘包括:底盘本体和多个电池部件。底盘本体包括一对第一纵梁、一对第二纵梁、第一横梁以及第二横梁。一对第二纵梁布设于一对第一纵梁的两侧,第一横梁与第一纵梁和第二纵梁的同一端连接,第二横梁与第一纵梁和第二纵梁的另一端连接。第一横梁、第二横梁以及一对第一纵梁之间围合形成装配区,第一横梁、第二横梁、第一纵梁以及第二纵梁围合形成缓冲区。多个电池部件均分布在装配区内。本申请通过将多个电池部件分布于底盘本体上形成的装配区,释放电池部件占用的整车高度空间,提高乘员舱空间利用率。底盘本体处空间大,电池部件分布于该处的装配区,提高电池空间比能。
