The invention belongs to the technical field of automobile interior structures, and particularly relates to a structure of PET foam on an automobile roof. Comprising an upper shell and a lower shell, first skylight through holes are symmetrically formed in the upper shell, second skylight through holes corresponding to the first skylight through holes are formed in the lower shell, and a PET foam forming embedded assembly is arranged between the upper shell and the lower shell in a matched mode. Through installation of the upper shell body and the lower shell body, rapid installation and fixation of the ceiling structure are achieved, and the upper shell body and the lower shell body which are separated are arranged so that the ceiling structure can be disassembled more easily when a vehicle needs to be maintained in the later period; after the upper shell body and the lower shell body are installed, the PET foam is filled through the material injection holes, in this way, the space between the upper shell body and the lower shell body can be fully filled, the overall integrity is better, the characteristics of the PET foam are fully played, and the performance of the automobile roof is more excellent.

    本发明属于汽车内饰结构技术领域,具体涉及一种PET泡沫在汽车顶棚结构。包括上壳体和下壳体,所述上壳体上对称设有天窗通孔一,所述下壳体对应天窗通孔一设有天窗通孔二,所述上壳体和下壳体之间配合设有PET泡沫成型内嵌组件。本发明通过上壳体和下壳体的安装,实现了顶棚结构的快速安装和固定,在设置分开的上壳体和下壳体是方便后期车辆需要维修时能够更加简单的进行拆卸;在安装好上壳体和下壳体后,通过注料孔进行PET泡沫的填充,这样的填充方式,能够获得上壳体和下壳体之间充分的填充,使得整体的一体性更好,充分发挥PET泡沫的特性,汽车顶棚的性能更加优秀。
