The invention provides an electric automobile chassis frame and an automobile. The chassis frame of the electric automobile comprises a battery module, a front frame and a rear frame. The battery module comprises a battery frame main body, a battery lower shell, a battery upper cover and a battery cell, according to the technical scheme, the novel design of the chassis frame of the electric automobile is provided, the battery frame body of the battery module serves as the structural body of the middle frame, and the four frame side edges of the battery frame body form the front floor rear cross beam, the rear floor front cross beam and the two threshold side beams correspondingly; therefore, the structure of the middle frame does not need to be additionally constructed. Meanwhile, the structural main body of the middle frame can be directly used as the outer frame of the battery module, so that the outer frame of the battery can be saved, the battery cell mounting space is increased, and the effect of improving the battery capacity is achieved.
本发明提供了一种电动汽车底盘车架及汽车。该电动汽车底盘车架包括电池模块、前车架和后车架。电池模块包括电池框架主体、电池下壳体、电池上盖和电芯。本发明的技术方案提供了一种新的电动汽车底盘车架的设计,将电池模块的电池框架主体作为中车架的结构主体,让电池框架主体的四条框架侧边分别构成前地板后横梁、后地板前横梁以及两个门槛边梁,这样就不用额外构建中车架的结构了。同时,也可以理解为中车架的结构主体可以直接作为电池模块的外边框,从而可以省去电池外边框,增大电芯安装空间,从而达到提高电池容量的效果。
