The rear side door structure comprises a rear inner plate, a first anti-collision beam, a reinforcing pipe beam and a second anti-collision beam, the first anti-collision beam is arranged at the front end of the rear inner plate and matched with the rear inner plate in shape to form a first closed cavity, and the first anti-collision beam is formed by the top of the front end of the rear inner plate, the reinforcing pipe beam and the second anti-collision beam. And the bottom of the rear inner plate extends. The reinforcing tubular beam is arranged on the first anti-collision beam and extends to the bottom of the first anti-collision beam from the top of the front end of the first anti-collision beam, so that the reinforcing tubular beam is in surface contact with a threshold assembly of the vehicle. The second anti-collision beam is in surface contact with the reinforcing tubular beam, and the second anti-collision beam extends along the top of the reinforcing tubular beam, so that the second anti-collision beam is in surface contact with a roof side rail assembly of the vehicle. The rear inner plate, the first anti-collision beam, the reinforcing tubular beam and the second anti-collision beam are integrated to replace a B column, so that the side anti-collision performance of the vehicle is improved, meanwhile, the number of parts of the vehicle is reduced, and the user experience feeling is improved.

    本发明涉及一种后侧门结构、车门组件以及车辆,涉及车辆技术领域,本发明包括后内板、第一防撞梁、加强管梁以及第二防撞梁,第一防撞梁设置于后内板的前端,且与后内板形状配合形成一第一封闭腔体,第一防撞梁由后内板的前端的顶部,延伸至后内板的底部。加强管梁设置于第一防撞梁上,且加强管梁由第一防撞梁的前端的顶部,延伸至第一防撞梁的底部,以使加强管梁与车辆的门槛总成面接触。第二防撞梁与加强管梁面接触,且第二防撞梁沿加强管梁的顶部延伸,以使第二防撞梁与车辆的上边梁总成面接触。综合后内板、第一防撞梁、加强管梁以及第二防撞梁来替代B柱,从而在提高车辆的侧面防碰撞性能的同时,降低车辆的零部件数量和提高用户体验感。
