The invention discloses an automobile tail door and an automobile, and relates to the technical field of automobiles. The automobile tail door comprises an inner plate, an outer plate and a reinforcing assembly. The inner side of the inner plate is provided with a lightweight optimization structure used for enhancing the structural rigidity and reducing the material consumption. The outer plate is attached to the outer side of the inner plate to form a tail door main body, and the tail door main body is made of a plastic material; the reinforcing assembly is fixed to the tail door body and used for enhancing the structural rigidity of the tail door body. According to the plastic tail gate structure provided by the invention, an optimized structure, namely an X-shaped lightweight optimized structure, is obtained by adopting a plastic material which is lighter in mass and better in forming freedom degree through an optimal material distribution optimization method, so that the rigidity performance requirement of the tail gate structure is met, and meanwhile, the lightweight effect of the whole tail gate structure is realized.

    本发明公开了一种汽车尾门及汽车,涉及汽车技术领域。该汽车尾门包括内板、外板以及加强组件;内板的内侧上设有用于增强结构刚度并减少材料用量的轻量优化结构;外板贴靠安装于内板的外侧上并构成尾门主体,尾门主体为塑料材质;加强组件固定于尾门主体上,以用于尾门主体增强结构刚度。本发明提出了一种塑料尾门结构,通过采用质量更轻,成型自由度更优的塑料材质,并通过最佳材料分布优化方法获得的优化结构,即“X”字形轻量优化结构,满足了尾门结构刚度性能要求的同时,实现了尾门整体结构的轻量化效果。
