The invention relates to the technical field of vehicle bodies, in particular to a B-column-free vehicle body structure, a vehicle and an assembling method of the B-column-free vehicle body structure. The B-column-free vehicle body structure comprises a front windshield assembly, a top cover longitudinal beam, a top cover rear assembly, a back door assembly and a lower vehicle body assembly; the front end of the top cover longitudinal beam is fixedly connected with the middle of the upper end of the top cover rear assembly. Gull-wing door installation parts are arranged on the left side and the right side of the middle of the top cover longitudinal beam. The lower end of the front windshield assembly is fixedly lapped with the front part of the lower vehicle body assembly, the lower end of the top cover rear assembly is fixedly lapped with the rear part of the lower vehicle body assembly, and the back door assembly is fixedly connected with the rear sides of the top cover rear assembly and the lower vehicle body assembly; the front windshield assembly, the top cover longitudinal beam, the top cover rear assembly, the back door assembly and the lower automobile body assembly are all aluminum alloy integrally-cast forming parts. The European wing type opening mode of the whole side vehicle door can be met, and on the premise that the performance is met, light-weight and lean design and production of a vehicle body are achieved.
