The invention discloses a passenger car aluminum body side wall framework structure which comprises a left side wall framework, a right side wall framework, a top cover framework, a front wall framework and a rear wall framework. The left side wall framework and the right side wall framework are basically the same in structural form and comprise window stand columns, cross beams, waist beams and cabin stand columns, the waist beams are through front and back, the section of each waist beam is of a truss type structure, the window stand columns are connected above the waist beams, the cabin stand columns are connected below the waist beams, and the window stand columns and the cabin stand columns are not located on the same side wall thickness; the cross beam is connected to the window stand column. The method is particularly suitable for B-level, II-level and III-level passenger cars in M2 and M3 types, the problem that the strength of an upper structure is reduced in the aluminum tempering process is solved, and meanwhile it is guaranteed that a luggage compartment below the side surrounding waist beam is normally arranged.
