A high-speed motor train unit middle train underframe end structure is characterized in that a coupler seat, a draft sill and an underframe connection board are installed and welded to be of an integrated structure; two vertical boards are connected with the rear face of the coupler seat; the rear faces of the two vertical boards are connected with end board assemblies; the coupler seat, the two vertical boards and the end board assemblies define an overall cavity structure; the two sides of the end board assemblies are of an inward concave structure to form an electric connector installation interface; the two sides of a bottom board are welded to side apron boards; the upper surface of the bottom board is welded to the draft sill; two rectangular holes are formed in the bottom board and provide a maintenance space for end inner connectors; the ends of the whole underframe are welded to be of an overall stressed box-type structure. The whole structure is formed in a welding mode, longitudinal force borne on a train coupler is transmitted to a floor through the drift sill, the underframe connection board and the bottom board, force borne on the coupler seat is backwards transmitted through the underframe connection board and the bottom board, the front portion of the coupler seat defines a coupler box through the end board assemblies and the vertical boards to be used for installation of the coupler, the overall type stressed underframe end structure meets the intensity requirement, the welding process is simple, the product structure is achieved through a few tools, and the manufacturing period is shortened.
