The plastic tail door structure with the improved mechanical property comprises a tail door inner plate and a tail door outer plate, the top of the tail door inner plate is provided with a hinge part hinged to a carriage, and the bottom of the tail door inner plate is provided with a vehicle lock part connected with the carriage in a locked mode. Glass mounting parts are correspondingly arranged between the tops and the bottoms of the tail door inner plate and the tail door outer plate; a plurality of metal plate reinforcing parts are arranged on the positions, corresponding to the hinge part, the vehicle lock part and the glass installation part, of the tail door inner plate, a plurality of supporting reinforcing parts are arranged between the tail door inner plate and the tail door outer plate in a bilateral symmetry mode relative to the perpendicular bisector of the tail door inner plate, and a plurality of functional unit installation parts are arranged on the tail door inner plate and/or the tail door outer plate. The mechanical property requirement of the vehicle tail door structure can be met, it is guaranteed that the vehicle tail door structure has enough anti-bending-torsional rigidity, fatigue resistance and concavity resistance, meanwhile, the light-weight plastic tail door structure can be guaranteed, and the design generation period of the plastic tail door structure is shortened.
