The invention provides a height-expandable automobile chassis and an automobile, the automobile chassis comprises a middle-area frame, the middle-area frame comprises a plurality of first automobile body supports and a passenger compartment floor, the first automobile body supports surround the passenger compartment floor to be connected to form a frame structure with a groove-shaped section, and the interior of the frame structure is used for providing a battery pack arrangement area; the mounting longitudinal beams are connected to the two ends, in the X direction, of the middle-area vehicle frame, and the mounting longitudinal beams are connected with the suspension structures; wherein the middle-area frame and the mounting longitudinal beam are arranged in parallel, and the middle-area frame and the mounting longitudinal beam have an adjustable height difference in the Z direction, so that the heights of an automobile chassis and a grounding point are changed according to the type of the whole automobile. The middle-area frame and the mounting longitudinal beam are arranged to have adjustable height difference in the Z direction, so that expansion of various vehicle types with the same bandwidth can be realized. According to the automobile chassis, most complexity can be avoided in design, and development of repeated and expensive extrusion parts and castings is avoided.

    本发明提供了一种高度可拓展的汽车底盘及汽车,汽车底盘包括:中区车架,中区车架包括多个第一车体支架和乘员舱地板,第一车体支架围合乘员舱地板连接呈一截面为槽型的框体结构,框体结构内部用于提供电池包布置区域;多根安装纵梁,安装纵梁连接在中区车架沿X方向上的两端,安装纵梁连接悬架结构;其中,中区车架和安装纵梁平行设置,且中区车架和安装纵梁在Z方向具备可调节的高度差,进而根据整车车型改变汽车底盘和接地点的高度。通过将中区车架和安装纵梁在Z方向设置为具备可调节的高度差,可以同带宽各种车型的拓展。此汽车底盘可在设计避免了大部分的复杂性,避免开发重复昂贵的挤压件和铸件。
