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.

    本发明公开了一种改善力学性能的塑料尾门结构,包括尾门内板与尾门外板,所述尾门内板的顶部设置有与车厢铰接的铰链部,所述尾门内板的底部设置有与车厢锁定连接的车锁部,所述尾门内板与尾门外板的顶部与底部之间对应设置有玻璃安装部;所述尾门内板上对应铰链部、车锁部、玻璃安装部的周围设置有若干钣金加强部,所述尾门内板与尾门外板之间关于尾门内板的中垂线左右对称设置有若干支撑加强部,所述尾门内板和/或尾门外板上设置有若干功能单元安装部;本发明既能满足车辆尾门结构的力学性能要求,保证车辆尾门结构具有足够的抗弯扭刚度、抗疲劳度、抗凹度,同时又能保证轻量化塑料尾门结构,缩减塑料尾门结构的设计产生周期。
