The invention provides a plastic back door inner plate, and belongs to the technical field of automobile parts. The longitudinal beams are arranged in the inner plate main body frame, and the number of the longitudinal beams is at least two; the longitudinal beams are arranged in the inner plate body frame, the transverse beams are arranged in the inner plate body frame, the number of the transverse beams is at least two, and the longitudinal beams and the transverse beams are arranged in a crossed mode. The invention further provides an automobile back door which comprises the plastic back door inner plate and further comprises a plastic back door outer plate, and the plastic back door outer plate is connected with the plastic back door inner plate. The plastic back door inner plate has the beneficial effects that the longitudinal beams and the transverse beams are connected with the inner plate main body frame, the transverse beams can effectively improve the lateral rigidity and the torsional rigidity of the plastic back door inner plate, the longitudinal beams can effectively improve the bending rigidity of the plastic back door inner plate, and under the action of the longitudinal beams and the transverse beams in two different directions, the plastic back door inner plate can be fixed. The overall rigidity of the plastic back door inner plate can be effectively improved.

    本发明提供了一种塑料背门内板,属于汽车零部件技术领域,包括:内板主体框架;纵向梁,其设置于所述内板主体框架内,所述纵向梁的数量至少为两个;横向梁,其设置于所述内板主体框架内,所述横向梁的数量至少为两个,所述纵向梁与所述横向梁交叉设置。还提供了一种汽车背门,包括所述的塑料背门内板,还包括:塑料背门外板,所述塑料背门外板与所述塑料背门内板连接。本发明的有益效果为:纵向梁以及横向梁与内板主体框架相连,横向梁能够有效提升塑料背门内板的侧向刚度和扭转刚度,纵向梁能够有效提高塑料背门内板的弯曲刚度,在纵向梁以及横向梁两个不同方向的作用下,能够有效提升塑料背门内板的整体刚度。
