The invention relates to a rear floor structure, a rear casting of the rear floor structure and a vehicle, the rear floor structure comprises a rear floor front section assembly and the rear casting, the front end of the rear casting forms an accommodating space for accommodating the rear floor front section assembly, and the two transverse sides of the rear casting are respectively connected with threshold boundary beams on the two sides. The bottom of the rear floor front section assembly is provided with a first sealing face used for forming sealing with the battery pack assembly, the bottom of the doorsill edge beam is provided with a second sealing face used for forming sealing with the battery pack assembly, a height difference exists between the first sealing face and the second sealing face, and a sealing reinforcing structure is arranged at the connecting position of the rear casting and the doorsill edge beam. A transition sealing face is formed on the sealing reinforcing structure and is in smooth butt joint with the first sealing face and the second sealing face in the transverse direction. Smooth butt joint between the rear floor sealing face and the doorsill edge beam sealing face with the height difference can be guaranteed, a continuous sealing face is formed, a plurality of sealing reinforcing structures can be arranged in the longitudinal direction to adapt to vehicle types with different wheelbases, and platform generalization is achieved.
本发明涉及一种后地板结构、后地板结构后铸件以及车辆,包括后地板前段总成和后铸件,后铸件的前端形成有容置后地板前段总成的容置空间,后铸件的横向两侧分别连接两侧的门槛边梁,后地板前段总成底部设有用于与电池包总成形成密封的第一密封面,门槛边梁底部设有用于与电池包总成形成密封的第二密封面,第一密封面与第二密封面之间存在高度差,后铸件与门槛边梁的连接处设有密封加强结构,密封加强结构形成有过渡密封面,过渡密封面沿横向平滑对接第一密封面和第二密封面。本发明能够确保存在高差的后地板密封面与门槛边梁的密封面之间平滑对接,形成连续的密封面,并能够通过沿纵向设置多个密封加强结构以应对不同轴距车型,实现平台通用化。
