The invention relates to the technical field of vehicles, in particular to a lightweight cavity beam type vehicle frame of an electric vehicle. The lightweight cavity beam type vehicle frame comprises a front cavity body assembly, a center cavity, a back cavity body assembly, a vertical and horizontal beam frame and an auxiliary vehicle frame, wherein the front cavity body assembly comprises front saddle cavities, a front luggage cavity and front hanging cavities; the center cavity is positioned in the center of a chassis and in glue connection with the vertical and horizontal beam frame so as to form a whole, and the center cavity as a main bearing component of the structure is the mounting base of a power package and a battery package; the back cavity body assembly comprises back saddle cavities, a back luggage cavity and back hanging cavities; the vertical and horizontal beam frame is divided into two layers, an upper-layer vertical and horizontal beam frame is in glue connection with the front cavity body assembly and the back cavity body assembly through cap-shaped components, and a lower-layer vertical and horizontal beam frame is in glue connection with the center cavity through the cap-shaped components. The lightweight cavity beam type vehicle frame disclosed by the invention adopts a structure compositing a carbon fiber cavity body and an aluminum alloy beam, under the conditions that the structural strength and the structural rigidity are guaranteed, the weight lightening of the vehicle is realized, besides the vehicle frame is divided into five modules, the vehicle frame is convenient to efficiently design and rapidly manufacture, and the structure is further easy to mount and quickly replace the power package and the battery package.
