The invention relates to the technical field of rail train doors, in particular to a large-opening-degree translation train door structure. The structure comprises a pulling mechanism, a door pushing mechanism and a supporting mechanism. Wherein the pulling mechanism comprises a pulling sliding block and a connecting plate; the sliding block is pulled to slide on the carriage; one end of the connecting plate is fixedly connected with the sliding block, and the other end of the connecting plate is fixedly connected with the top end of the vehicle door; the door pushing mechanism comprises a lifting block and a rotating arm; the lifting block slides up and down at the bottom of the carriage; one end of the rotating arm is hinged with the bottom end of the vehicle door, and the other end droops freely; the supporting mechanism comprises a supporting guide rail, a supporting seat, a sliding rod and a spring; the supporting guide rails are fixedly connected with the carriage bottom; the supporting seat slides on the supporting guide rail; one end of the sliding rod is fixedly connected with the lower end of the vehicle door, and the other end of the sliding rod is in sliding connection with the supporting seat; and one end of the spring is fixedly connected with the sliding rod, and the other end is fixedly connected with the supporting seat. The large-opening-degree translation vehicle door structure is provided for overcoming the defects in the prior art, and the cargo loading and unloading efficiency is improved.
