The invention discloses a 16-ring pure electric platform vehicle body structure of a passenger vehicle. The 16-ring pure electric platform vehicle body structure comprises a left side wall assembly, aright side wall assembly, a top cover skylight, a lower vehicle body assembly, a front top cross beam assembly, a rear top cross beam assembly, a rear wall outer plate assembly, a left front wheel cover edge beam assembly and a right front wheel cover edge beam assembly. The advanced 16-ring ball cage type vehicle body framework structure is adopted, the weight of the vehicle body is remarkably reduced, and the collision, bending and twisting performance and the like of the whole vehicle are improved. Through the new materials, the new process and the new structure, the steel-aluminum mixed vehicle body is achieved, the vehicle body performance reaches the foreign-invested brand level, the torsional rigidity reaches over 27000 N/mm, the light weight coefficient reaches the excellent levelof 2.81, the whole vehicle safety reaches the five-star collision safety performance of the C_NCAP of the 2018 edition, and the whole vehicle body performance reaches the excellent B-grade vehicle foreign-invested brand level.
