Abstract

The invention relates to the technical field of automobiles, and discloses a vehicle rear side wall structure, in the scheme, a front protective plate and a threshold reinforcing plate are connected, so that the front end and the rear end of a vehicle are reliably connected, a force transmission path between the front end and the rear end of the vehicle is effectively connected, and when the vehicle collides, the vehicle can be prevented from being damaged. Collision force at the front end or the rear end of the vehicle can be reliably transmitted through the doorsill reinforcing plate and the front protective plate which are connected, the rigidity of the overall structure of the vehicle is improved, and the safety of the vehicle during collision is improved. Meanwhile, the side wall inner plate close to the tail gate is deformed towards the interior of the vehicle to form a concave cavity, a D column is further formed through the D column upper outer plate and the first plate which cover the concave cavity, a closed cavity is formed in the D column, and the structural strength of the tail end of the vehicle is improved.
