The automobile door outer plate comprises the automobile door outer plate body made of plastic, at least one reinforcing plate is arranged on the inner side of the automobile door outer plate body, and the reinforcing plate is of a honeycomb structure composed of a plurality of ribs. The ribs comprise a plurality of transverse ribs which are parallel to one another, and a plurality of left inclined ribs and right inclined ribs which are inclined towards two sides; the transverse ribs, the left inclined ribs and the right inclined ribs are all made of plastics in an integrated injection molding mode, the transverse ribs, the left inclined ribs and the right inclined ribs jointly form a plurality of equilateral triangle structures, and the thickness of the automobile door outer plate is larger than or equal to 3 MM. The beneficial effects of the invention are that the device is light in weight, is easy to shape, and provides more safety protection possibilities for loading electronics; and the honeycomb structure is strictly calculated, so that the honeycomb structure has lower mass density and also has very high rigidity ratio, strength ratio, energy absorption and collapse energy.

    本发明公开了车门外板及车门,包括由塑料制成的车门外板,所述车门外板内侧设置有至少一个加强板,所述加强板是由若干个筋条组成的蜂窝结构,所述筋条包括若干个相互平行的横向筋条、以及若干个向两侧倾斜的左斜筋条和右斜筋条;所述横向筋条、左斜筋条和右斜筋条都是由塑料一体注塑成型的,所述横向筋条、左斜筋条和右斜筋条共同组成若干个等边三角形结构,所述车门外板的厚度大于等于3MM;本发明的有益效果是:重量轻、易塑形、提供更多装载电子安全防护可能;蜂窝结构进行严格的计算,具有更低的质量密度,同时具有很高的刚度比、强度比和吸能及溃能。
