The invention discloses a double-layer wind resistance braking device, a double-layer cab structure and a high-speed train. The double-layer wind resistance braking device comprises an outer-layer wind resistance braking plate and an inner-layer wind resistance braking plate which are installed in a variable cross-section area of the train, the outer-layer wind resistance braking plate comprises aplurality of outer-layer braking unit plates which are transversely arranged along the outer contour of the variable cross-section area, the inner-layer wind resistance braking plate comprises a plurality of inner-layer braking unit plates which are transversely arranged along the outer contour of the variable cross-section area, an opening and closing driving mechanism is installed on a high-speed train cab, and when the outer-layer wind resistance braking plate and the inner-layer wind resistance braking plate are opened, the inner-layer braking unit plates are located on the inner side ofthe outer-layer braking unit plate and located in gaps between adjacent outer-layer braking unit plates. The double-layer wind resistance braking device, the double-layer cab structure and the high-speed train are simple in structure, convenient to install and high in reliability, the requirement of the high-speed train for braking force in the emergency braking state can be met, and the problem that the braking force is insufficient when the high-speed train is braked emergently is solved.
