The embodiment of the invention provides a flexible-compensation-type jumper wire structure for a rail vehicle. The flexible-compensation-type jumper wire structure comprises a vehicle hook and two flexible-compensation-type jumper parts, wherein one flexible-compensation-type jumper part is arranged at each of the two ends of the vehicle hook; each flexible-compensation-type jumper part comprisesa mounting part, a rotating part and a movable part; the mounting part is arranged on the vehicle hook; the mounting part and the movable part are rotationally connected with the rotating part respectively; an elastic component is arranged between the movable part and the mounting part; and a wire holder is arranged on the movable part. Jumper wires are connected to the movable parts through thewire holders, and the movable parts rotate clockwise or counterclockwise around the rotating part, so that the problems that in the prior art, because of reduction in the relative distance between theend surfaces on the curved inner sides of trains as well as too small distance between the lower sides of the jumper wires and a rail surface when the vehicle passes through a curve, a certain hiddendanger exists, waste of cables is caused and the design cost and the running energy consumption are increased are avoided.
