The invention discloses a thermal forming door ring, a B column reinforcing plate, a vehicle body side wall assembly and a vehicle. The thermal forming door ring comprises an A column reinforcing plate, a doorsill reinforcing plate, the B column reinforcing plate and an A column vertical plate. One end of the B column reinforcing plate is welded with the A column reinforcing plate, the other end of the B column reinforcing plate is welded with the threshold reinforcing plate, and the threshold reinforcing plate and the A column reinforcing plate are oppositely arranged; one end of the A column vertical plate is welded to the end, away from the B column reinforcing plate, of the A column reinforcing plate, the other end of the A column vertical plate is welded to the end, away from the B column reinforcing plate, of the threshold reinforcing plate, the A column vertical plate and the B column reinforcing plate are oppositely arranged, and the B column reinforcing plate is provided with a first transition plate, a second transition plate connected with the first transition plate and a reinforcing plate connected with the second transition plate. The plate thickness of the reinforcing plate is larger than that of the second transition plate and that of the first transition plate. According to the thermal forming door ring disclosed by the embodiment of the invention, the deformation can be resisted, and meanwhile, the light weight of the structure is realized.
