The invention belongs to the technical field of high-speed trains, and particularly relates to a stepless telescopic lift wing of a high-speed train. Comprising a skin assembly, a supporting assembly and a telescopic assembly, and the telescopic assembly is arranged in the supporting assembly and used for stretching and retracting of the movable wing rib and the movable skin; the telescopic assembly comprises at least two electric telescopic push rods which are symmetrically arranged on the two sides of the fixed wing rib, one end of each electric telescopic push rod is fixed to the movable wing rib on the outermost side, and the other end of each electric telescopic push rod is hinged to the fixed wing rib. One end of each crossed connecting rod assembly is hinged to the movable wing rib on the outermost side, the other end of each crossed connecting rod assembly is hinged to the fixed wing rib, the electric telescopic push rods can achieve precise stretching and retracting and have the load braking function, and the crossed connecting rod assemblies can achieve synchronous translation of the movable wing ribs on one side or the movable wing ribs on the two sides. And stretching is conducted according to the external running environment and running requirements of the train, and the influence of airflow on train running in different running environments is reduced.
