Aluminum alloy integrated die-casting rear floor structure of new energy automobile

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 framew
