In the frame and battery compartment integrated chassis structure, two side battery compartments are symmetrically arranged on the outer sides of a left longitudinal beam and a right longitudinal beam, a central battery compartment is arranged between the left longitudinal beam and the right longitudinal beam, and four bottom beams are transversely arranged at the bottoms of the three battery compartments at intervals; the battery compartment assembly is detachably assembled between two longitudinal beams of the frame and on the left side and the right side of the frame through the mounting hole positions at the bottoms of the longitudinal beams of the frame and the mounting hole positions of the four bottom beams; according to the structure, the battery compartment and the frame can be highly integrated, the left longitudinal beam web plate and the right longitudinal beam web plate of the frame serve as one side vertical plate of the two side face battery compartments, the number of parts of the two side face battery compartments is reduced, the light weight of the battery compartment structure is achieved, a power battery system is better protected, and the structural strength and the bending rigidity of the frame are improved; the control stability and safety of the whole vehicle are improved, and overall battery replacement of the battery compartment is facilitated.
本发明公开的一种车架与电池仓一体化集成底盘结构中,两个侧面电池仓对称设置在左右纵梁外侧,中央电池仓设置在左右纵梁之间,四根底梁横向间隔设置在三个电池仓的底部,通过车架纵梁底部的安装孔位和四根底梁的安装孔位将电池仓总成可拆卸地装配在车架的两纵梁之间及其左右两侧;该结构可将电池仓与车架一体化高度集成,把车架左右纵梁腹板作为两个侧面电池仓的一侧立板,减少了两个侧面电池仓的零件数量,实现了电池仓结构轻量化,更好地保护动力电池系统,提高车架的结构强度、弯扭刚度,改善整车操纵稳定性和安全性,便于实现电池仓整体换电。
