The invention belongs to the technical field of electric vehicles, and discloses an electric commercial vehicle frame which comprises a front frame, a middle frame and a rear frame, the middle frame is connected with the front frame and comprises a cross beam part and a longitudinal beam part, the cross beam part is connected with the longitudinal beam part through an outer angle mounting piece, and the rear frame is connected with the middle frame through a rear angle mounting piece. The longitudinal beam part forms a frame for accommodating a battery pack, the longitudinal beam part is provided with a plurality of battery pack mounting structures, and the plurality of battery pack mounting structures are sequentially arranged along the extension direction of the longitudinal beam part; and the rear frame is connected with the middle frame. On one hand, the installation space of the battery pack is increased, the occupied space of the whole frame is reduced, and through the multiple battery pack installation structures arranged on the longitudinal beam part, the battery pack can be installed in a multi-point mode, the stress of the battery pack is evenly dispersed on the frame, and therefore the durability of an automobile is improved; and on the other hand, the structure is simpler, the process is simpler, and the bending rigidity and the torsional rigidity are higher.

    本发明属于电动汽车技术领域,公开了一种电动商用车车架,包括:前车架、中车架和后车架,所述中车架与所述前车架连接,所述中车架包括横梁部分和纵梁部分,所述横梁部分与所述纵梁部分通过外角安装件连接,构成用于容纳电池包的框架,所述纵梁部分设有电池包安装结构,多个电池包安装结构沿所述纵梁部分的延伸方向依次设置;所述后车架与所述中车架连接。一方面,提升了电池包的安装空间,缩小了整个车架的占用空间,且通过设置在纵梁部分的多个电池包安装结构,使得电池包能够多点安装,将电池包的应力均匀的分散在车架上,从而提高汽车的耐久度;另一方面,结构更简单,工艺更简单,且弯曲刚度和扭转刚度更高。
