The invention relates to a modular light full-bearing passenger car body annular portal frame unit. The modular light full-bearing passenger car body annular portal frame unit comprises annular portal frame frameworks, a car frame, torsion-resistant longitudinal beams and car body structural plates. The two annular portal frame frameworks are symmetrically arranged. The car frame is fixedly connected with the lower ends of the two annular portal frame frameworks. Each annular portal frame framework comprises a top cross beam and lateral vertical beams, wherein the lateral vertical beams are symmetrically arranged at the two ends of the top cross beam, and the two ends of the top cross beam are fixedly connected with the upper ends of the lateral vertical beams at the two ends through connecting pieces respectively. The torsion-resistant longitudinal beams are fixed to the two ends of each top cross beam respectively, are perpendicular to the top cross beams and the lateral vertical beams and connected with the two annular portal frame frameworks. The car body structural plates are fixedly arranged between the top cross beams of the two annular portal frame frameworks as well as between every two opposite lateral vertical beams respectively. According to the modular light full-bearing passenger car body annular portal frame unit, a car body frame is composed of a plurality of annular portal frame units, so that modular production is facilitated, production efficiency is improved, and different types of passenger cars can be spliced according to requirements.
