摘　　要：传统汽车顶盖具有曲面面积大、表面质量要求高、成型工序复杂等特点。文章主要针对采用旋塑工艺的全塑车身结构,综合传统的汽车顶盖和汽车顶棚结构设计特点,提出一种采用"三明治"复合材料的车身顶盖结构,以达到集成零部件功能,精简了工艺步骤,减少了冲模制造成本的效果。The traditional car roof had many characteristics, such as a large area, a high-surface-quality requirement and a complex molding process. Based on the structure of all-plastic car body produced by rotational molding, a car roof structure with the ＂sandwich＂ composite was proposed by synthesizing structural design features of the traditional ear roof and car ceiling in order to achieve integration of components, simplification of process steps and reduction of manufacturing cost of dies.
