An electric vehicle frame system, including two multi-cavity box type longitudinal beams which are arranged symmetrically and are made of an aluminum alloy material, and a multi-cavity transverse beam assembly which is connected between the two multi-cavity box type longitudinal beams and is made of aluminum alloy material, wherein the multi-cavity box type longitudinal beam is provided internally with multiple independent cavities, and the multi-cavity transverse beam assembly includes multiple transverse beams which are provided internally with multiple independent cavities; and further having a front bumper system and a rear bumper system which are respectively provided at both ends of the multi-cavity box type longitudinal beams, and a B pillar holder provided in the middle of the multi-cavity box type longitudinal beams. The multi-cavity box type longitudinal beams and the multi-cavity transverse beam assembly are made of an aluminum alloy profile, such that not only a support structure is formed to support the body of the electric vehicle, but also the overall weight of the frame can be reduced; and the frame has a simple structure, is easy to process and mold, can greatly simplify the production process and reduce production costs, and the independent cavities inside the frame can also be used as cable channels, oil pipelines and other pipelines.
