The aluminum alloy integrated die-casting rear floor structure of the new energy automobile comprises an integrally-formed rear floor framework, an opening vertically penetrating through the rear floor framework is formed in the rear floor framework, protrusions are arranged on the left side and the right side of the front end of the rear floor framework, and the protrusions are fixedly connected with a doorsill beam of an automobile body. The left side and the right side of the rear end of the rear floor framework are fixedly connected with rear floor edge beams of a vehicle body, reinforcing rib assemblies and mounting positions are distributed on the rear floor framework, and the rear floor framework is connected with the vehicle body or a shock absorber at the mounting positions. By arranging the integrally-formed rear floor framework, welding spots of the device in the production process are reduced so as to shorten the technological process, meanwhile, various reinforcing ribs are arranged on the framework so as to improve the structural strength of the whole device, and the structural strength of the whole device can be guaranteed while the functions of the whole device can be normally achieved.
本发明涉及一种新能源汽车铝合金一体化压铸后地板结构,包括一体成型的后地板骨架,所述后地板骨架内部开设有上下贯通其的开口,所述后地板骨架前端左右两侧设有凸起,凸起与车体的门槛梁连接固定,所述后地板骨架后端左右两侧与车体的后地板边梁连接固定,所述后地板骨架上分布设有加强筋组件和安装位,所述后地板骨架在安装位处与车体或者减震器相连。通过设置一体成型的后地板骨架,从而减小了装置在生产过程中的焊点,以缩短工艺流程,同时在骨架上设置多种加强筋,以提高整个装置的结构强度,使其能够正常行使功能的同时,保证了其结构强度。
