The invention provides a carbon fiber composite material automobile rear top cross beam assembly structure which consists of a rear top cross beam body, a back door left hinge reinforcing plate and a back door right hinge reinforcing plate, and the rear top cross beam body is fixedly connected with the lower end surface of an automobile body top cover; the back door left hinge reinforcing plate and the back door right hinge reinforcing plate are fixedly connected to the lower end face of the rear top beam body. The rear top beam body, the back door left hinge reinforcing plate and the back door right hinge reinforcing plate are all made of carbon fiber composite materials. The structure solves the problems that the rigidity and strength performance of a traditional rear top beam assembly of the vehicle body cannot meet the requirements, assembly is complex, rusting is prone to occurring, and the practicability and comfort of the whole vehicle are insufficient.

    一种碳纤维复合材料汽车后顶横梁总成结构,该汽车后顶横梁总成由后顶横梁本体、背门左铰链加强板和背门右铰链加强板组成,所述的后顶横梁本体与车身顶盖的下端面固定连接,所述的背门左铰链加强板和背门右铰链加强板固定连接在后顶横梁本体下端面;所述的后顶横梁本体、背门左铰链加强板和背门右铰链加强板均为碳纤维复合材料。本发明解决了传统的车身后顶横梁总成的刚度、强度性能难以满足要求,装配复杂,易出现锈蚀,整车的实用性和舒适性不足的问题。
