The invention belongs to the technical field of plastic tail doors, and provides a composite tail door inner plate cavity reinforcing structure which is arranged on the lower portion of a rear windshield area and comprises an inner plate cavity located in a space formed by a tail lamp reinforcing beam area, a supporting rod installation point area, a buffer block installation area and a door lock installation area. The whole layer of the inner plate cavity is in a U shape, at least one set of main body reinforcing beams and at least one door lock reinforcing beam are formed on the inner plate cavity, and the door lock reinforcing beams are located between the side edges of the main body reinforcing beams. The composite material tail door has the advantages that the reinforcing structure of the inner plate cavity is designed, the strength of the tail door is enhanced, meanwhile, the performance of the composite material tail door can be greatly improved, the performance of the composite material tail door is comprehensively better than that of a metal tail door, meanwhile, the development process problems such as the manufacturing process and the cost are considered, the weight is reduced by 30% or above, and the cost is reduced by 15% or above.
本发明属于塑料尾门技术领域,提供了一种复合材料尾门内板腔体加强结构,设置在后风挡区域下部,包括有内板腔体,内板腔体位于尾灯加强梁区域、撑杆安装点区域、缓冲块安装区域以及门锁安装区域所形成的空间内,内板腔体整体层U字型,且内板腔体上形成有至少一组主体加强梁以及至少一条门锁加强梁,门锁加强梁位于主体加强梁侧边之间。本发明的优点在于利用对内板腔体的加强结构进行设计,在增强尾门强度的同时,能够大幅提升复合材料尾门的性能,全面比肩金属尾门性能,同时兼顾制造工艺及成本等开发过程问题,使其重量降低30%以上,成本降低15%以上。
