The invention discloses a rear floor assembly, belongs to the technical field of automobile design, and adopts a high vacuum die casting process to integrate a plurality of sheet metal parts of an automobile rear floor into one piece, so that the weight of the rear floor is reduced, and the performance of a whole body in white is improved. A plurality of sheet metal parts are integrated into one die casting through an integrated design, so that production is facilitated, assembly of a vehicle is reduced, and light weight can be realized. The integrated cast aluminum middle and rear floor is designed on the basis of sheet metal data under the condition of ensuring no interference with surrounding environment parts in the process of synchronous development with the sheet metal, and according to the advantages of the cast aluminum structure, the performance of the whole body in white is ensured, the parts are reduced, the light weight of the body can be reflected, the torsional rigidity of the body can be improved, and the service life of the body is prolonged. And modes and the like. After integrated die casting is adopted, production places are reduced, meanwhile, the whole production period is shortened, and production cost is saved.

    本发明公开了一种后地板总成,属于汽车设计技术领域,本发明采用高真空压铸工艺将汽车后地板的多个钣金件集成一个件,降低后地板的重量,提升整个白车身的性能。通过集成设计将多个钣金件集成一个压铸件,不仅方便生产和减少车的组装,而且可以实现轻量化。本发明在跟钣金同步开发的过程中,保证不跟周围环境件的干涉条件下,在钣金数据的基础上设计一体化铸铝中后地板,根据铸铝结构的优势,保证整个白车身的性能,实现少件化,还能体现车身的轻量化,还能提升车身的扭转刚度,模态等各种性能。采用一体化压铸后,不仅减少了生产产地,同时降低了整个生产周期,节约生产成本。
