The invention provides a composite structure of a new energy automobile chassis and a battery pack and a new energy automobile. The composite structure comprises a bottom plate, a first supporting structure, a second supporting structure and a battery pack. The battery pack comprises a tray and a cover body; the tray comprises an inner wall plate and an outer wall plate, and a gap between the inner wall plate and the outer wall plate is filled with a foaming layer; the cover body comprises an outer plate, an inner plate and a foaming layer filled between the outer plate and the inner plate, and the inner wall plate, the outer wall plate, the outer plate, the inner plate and the bottom plate are all CFRP plates. Each of the tray and the cover plate is of a sandwich structure formed by two layers of CFRP plates and a middle foaming layer, the battery pack, the first supporting structure and the second supporting structure jointly play a supporting role, the strength and rigidity of the battery pack are good through the CFRP plates, the light weight effect is remarkable, and the weight of the composite structure of the new energy automobile chassis and the battery pack is effectivelyreduced. And the foaming layer can effectively preserve heat and insulate heat, so that the cruising ability of the new energy automobile is improved.
本发明提供了一种新能源汽车底盘和电池包的复合结构及新能源汽车,包括底板、第一支撑结构、第二支撑结构以及电池包;电池包包括托盘以及盖体;托盘包括内壁板和外壁板,内壁板和外壁板之间的间隙内填充有发泡层,盖体包括外板和内板以及填充于外板和内板之间的发泡层,内壁板、外壁板、外板和内板和底板均为CFRP板。托盘和盖板均由两层CFRP板以及中间的发泡层形成“三明治结构”,且电池包与第一支撑结构以及第二支撑结构共同起到支撑作用,CFRP板使得电池包的强度和刚性较好,轻量化效果显著,有效地减轻了新能源汽车底盘和电池包的复合结构的重量,而发泡层能够有效保温隔热,提升了新能源汽车的续航能力。
