The invention belongs to the technical field of plastic tail doors, and provides a composite tail door inner plate reinforcing structure, stand column reinforcing inserts are arranged between hinge areas and supporting rod mounting point areas at rear windshields on the two sides of a tail door, and the stand column reinforcing inserts and a tail door inner plate are integrally formed in an injection molding mode and connected in a wrapping mode. A post reinforcement insert connects the hinge region and the strut mounting point region. The tail door has the advantages that the reinforcing insert is designed to perfectly solve the problem of performance attenuation of a special area, the reinforcing insert is arranged on the tail door inner plate, performance is met, materials are saved, the comprehensive cost performance is the highest, meanwhile, various coating combination structures can be arranged, combined and used in a matched mode according to the performance and modeling requirements of a tail door system, and the cost performance is high. The static rigidity, the torsional rigidity, the bending rigidity and the like of the integral performance of the tail gate are matched for use, so that the rigidity and the strength of the tail gate are greatly improved.

    本发明属于塑料尾门技术领域,提供了一种复合材料尾门内板加强结构,在尾门两侧后风挡处的铰链区域和撑杆安装点区域之间布置有立柱加强嵌件,立柱加强嵌件与尾门内板一体注塑而成并包覆连接,立柱加强嵌件连接铰链区域与撑杆安装点区域。本发明的优点在于设计了加强嵌件完美的解决了特殊区域性能衰减问题,加强嵌件在尾门内板布置即满足了性能又节省了材料,综合性价比最高,同时可以根据尾门系统性能及造型要求排列组合搭配使用各种包覆组合结构,对尾门整体性能静态刚度、扭转刚度、弯曲刚度等高低搭配使用,大大提升的了尾门的刚度和强度。
