The invention relates to a rear floor assembly structure and an automobile, the rear floor assembly structure comprises two rear longitudinal beams, two rear longitudinal beam rear parts and a rear floor cross beam, the two rear longitudinal beams are distributed at intervals, and each rear longitudinal beam comprises a rear longitudinal beam main body part and a rear part joint connected with the rear longitudinal beam main body part; the rear longitudinal beam main body part and the rear joint are integrally cast and formed by aluminum alloy; the two rear longitudinal beam rear parts are connected to the two rear longitudinal beam rear part connectors respectively, the rear longitudinal beam rear parts are subjected to the aluminum extrusion technology, and protruding parts are formed on middle ribs in the rear longitudinal beam rear parts; the rear floor cross beam comprises a rear cross beam body, and the two ends of the rear cross beam body are connected to the rear longitudinal beam main body parts of the two rear longitudinal beams respectively. The rear portion of the rear longitudinal beam can improve the impact resistance and energy absorption effect of the whole vehicle during collision, the weight of the whole vehicle can be reduced, production procedures are reduced, the damage probability of a floor after integrated die casting is reduced, and therefore after-sales maintenance cost is reduced.
本申请涉及一种后地板总成结构及汽车,其包括两个后纵梁、两个后纵梁后部和后地板横梁,两个所述后纵梁间隔分布,所述后纵梁包括后纵梁主体部以及与所述后纵梁主体部连接的后部接头,所述后纵梁主体部与后部接头由铝合金一体铸造成型;两个所述后纵梁后部分别连接在两个所述后纵梁的后部接头上,所述后纵梁后部为铝挤出工艺,且内部的中间筋上形成有凸起部;所述后地板横梁包括后横梁,所述后横梁的两端分别连接于两个所述后纵梁的后纵梁主体部上。本申请后纵梁后部能够提升碰撞时整车抗冲击能力及吸能效果,本申请能够减轻整车重量,减少生产工序,降低一体压铸后地板损坏几率,从而减少售后维修成本。
