The invention discloses a front floor frame structure of an electric vehicle, which comprises a front baffle lower crossbeam, a pair of threshold beams, and a rear floor front crossbeam; There is a front floor inside, the lower beam of the front baffle, a pair of sill beams, and the front beam of the rear floor are all hollow aluminum profile structures, and the front floor is an aluminum plate structure. The design of the front floor frame structure of the electric vehicle is reasonable, and all the beam structures are made of hollow aluminum profiles, which are light in weight and high in structural strength, which is conducive to the lightweight of the electric vehicle, can effectively extend the mileage of the electric vehicle, and reduce the cost of use.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a front floor frame structure of the electric vehicle. Background technique [0002] As a new energy vehicle, electric vehicles have the advantages of energy saving and environmental protection. Electric vehicles are becoming more and more research hotspots in the automotive field. At present, the common problem in the field of electric vehicles is that the battery life of electric vehicles is limited, which limits the popularization and application of electric vehicles. [0003] The existing frame structure of the upper front floor of the car body is mostly a steel structure, which is heavy, which is not conducive to the lightweight of electric vehicles, and is not conducive to effectively prolonging the cruising range of electric vehicles. Moreover, the manufacturing, assembly and maintenance costs of metal parts are high, which is not conducive to reducing costs. Me...
