The invention discloses a lower front body structure of an electric automobile. The lower front body structure comprises a front floor frame structure, a front longitudinal beam and an anti-collision cross beam, wherein the front floor frame structure comprises a front baffle lower cross beam, a pair of door sill beams and a rear floor front cross beam, the front baffle lower cross beam and rear floor front cross beam are arranged between the pair of door sill beams, and a front frame is formed; the anti-collision cross beam is connected with the front end of the front longitudinal beam through a crash box; the rear end of the front longitudinal beam is connected with the front baffle lower cross beam through a connecting beam; the front baffle lower cross beam, the door sill beams, the rear floor front cross beam, the front longitudinal beam, the crash box and the connecting beam all adopt a hollow aluminum profile structure. All beam structures adopt the hollow aluminum profile structure, the weight is light, the structural strength is high, the crash effect and the weight can be both considered simultaneously, lightweighting of the electric automobile is facilitated, the endurance mileage of the electric automobile can be effectively prolonged, and the use cost is reduced.
