The invention relates to the technical field of automobiles, in particular to a pure electric automobile chassis system adopting a light-weight coach chassis structure. The pure electric automobile chassis system comprises two longitudinal girders and a plurality of cross beams, wherein the plurality of cross beams are distributed at different-height layer surfaces and different longitudinal positions of the two longitudinal girders and are connected with the two longitudinal girders in a tenoning mode to form an internally-stressed dual-longitudinal-girder multilayer chassis frame; the front part of the dual-longitudinal-girder multilayer chassis frame is connected with a front axle carrier; the front axle carrier is fixed by virtue of the two longitudinal girders; the rear part of the dual-longitudinal-girder multilayer chassis frame is connected with a rear axle carrier which is fixed by virtue of the two longitudinal girders; the front axle carrier is connected with a front axle assembly, and the rear axle carrier is connected with a rear axle assembly; the dual-longitudinal-girder multilayer chassis frame is provided with a drive assembly and an energy assembly. The overall structure of the longitudinal girders is good in rigidity; a processing of assembling the front and rear axle carriers and the chassis frame is simplified, connection is reliable, and integral stress is realized; by virtue of a multilayer floor structure, installation of batteries and motors is convenient and the chassis space is saved.
