An improved automobile seat back plate comprises a shell, the shell is composed of a polypropylene plastic foaming plate, and a first installation structural part, a second installation structural part, a third installation structural part and a fourth installation structural part are arranged on the upper left side, the upper right side, the lower left side and the lower right side of the back face of the shell respectively. The first mounting structural member, the second mounting structural member, the third mounting structural member and the fourth mounting structural member each comprise a bottom plate, each bottom plate is provided with a clamping structure, and reinforcing mesh ribs are embedded in the back face of the shell. The automobile seat back plate is manufactured by adopting an EPP (Expanded Polypropylene) material. The EPP is abbreviation of foamed polypropylene and is a high-crystallinity polymer/gas composite material with excellent performance. The EPP is small in density, light in weight and excellent in physical performance, under the condition that the same structure and the same mechanical performance are met, the seat back plate made of the EPP material is the lightest in weight, and the seat back plate is obviously superior to an injection molding seat back plate in the aspect of light weight of an automobile and is much lighter than a seat back plate made of a natural jute fiber plate material.
一种改进的汽车座椅背板,包括壳体,壳体由聚丙烯塑料发泡板构成,壳体背面的左上侧、右上侧、左下侧、右下侧分别设置有第一安装结构件、第二安装结构件、第三安装结构件和第四安装结构件,第一安装结构件、第二安装结构件、第三安装结构件和第四安装结构件均各自包括一个底板,底板上均各自设置有一个卡接结构,壳体背面嵌设有加强网筋。本发明采用EPP材料制造汽车座椅背板。EPP是发泡聚丙烯的缩写,是一种性能卓越的高结晶聚合物/气体复合材料。EPP密度小,质量轻,物理性能优良,在满足相同结构及力学性能的条件下,采用EPP材料制造的座椅背板质量最轻,在汽车轻量化这方面明显优于注塑座椅背板,比天然麻纤维板材料座椅背板也轻很多。
