The chassis structure comprises a vehicle frame and a power battery system, the vehicle frame is divided into a front vehicle frame section, a middle vehicle frame section and a rear vehicle frame section in the length direction, the front vehicle frame section, the middle vehicle frame section and the rear vehicle frame section are detachably connected through inter-section connecting assemblies, and the middle vehicle frame section is of a frame type multi-layer structure; the frame type multi-layer structure is at least divided into two accommodating spaces in the height direction; the power battery system at least comprises two lithium battery assemblies, and the two lithium battery assemblies are correspondingly arranged in the containing spaces respectively. The three sections of the frame are detachably connected, and the length and the width of the middle section of the frame are changed or increased or decreased, so that the wheelbase change is adjusted, and the size requirements of more battery packs are met; the middle section of the frame is of a frame type multi-layer structure, the battery pack is arranged in a containing space of the frame type multi-layer structure in a side face drawing and placing mode, and the requirements for overhauling equipment and sites are reduced.
本发明公开一种新能源重型汽车底盘结构及车辆,底盘结构包括车架及动力电池系统,车架沿长度方向划分为车架前段、车架中段以及车架后段,三段之间均通过段间连接组件可拆卸连接,车架中段为框架式多层结构,框架式多层结构在高度方向上至少被分隔为两个收容空间;动力电池系统至少包括两个锂电池组件,两个锂电池组件分别对应装设在收容空间内。本发明的三段车架之间可拆卸连接,通过更换增减车架中段的长度、宽度,以调整轴距变化,匹配更多的电池包尺寸需求;车架中段采用框架式多层结构,电池包采用侧面抽放的方式装设在框架式多层结构的收容空间内,减少对检修设备及场地的要求。
