The invention belongs to the technical field of automobile tail doors, and provides a composite tail door reinforcing structure which is characterized in that an inner plate is integrally formed by a metal piece and plastic particles, a frame type reinforcing beam and a supporting beam are formed on the inner plate, the frame type reinforcing beam and the inner plate form a triangular frame part, and the supporting beam extends from the bottom of the inner plate to the frame type reinforcing beam; the supporting beam is connected with the side wall of the frame type reinforcing beam. The tail door has the advantages that the frame type reinforcing beam, the supporting beam, the sealing beam, the structural beam and the metal piece which are integrally formed with the inner plate are used, the structures of the frame type reinforcing beam, the supporting beam, the sealing beam, the structural beam, the metal piece and the like are optimized, the weight is reduced, and meanwhile the performance enhancing target of the tail door can be met; the cost performance of the composite material tail door is improved, the whole light-weight tail door can reduce automobile wind resistance, and therefore oil consumption and power consumption are reduced.

    本发明属于汽车尾门技术领域,提供了一种复合材料尾门增强结构,由金属件和塑料粒子一体成型为内板,内板上形成有框式加强梁和支撑梁,框式加强梁与内板形成呈三角形框架部,支撑梁从内板的底部向框式加强梁处延伸,支撑梁与框式加强梁的侧壁连接在一起。本发明的优点在于使用复合材料利用与内板一体成型的框式加强梁、支撑梁、密封梁、结构梁以及金属件,框式加强梁、支撑梁、密封梁、结构梁以及金属件等结构进行优化,减轻重量的同时又可以满足尾门的增强性能目标,提高复合材料尾门的性价比,整个轻量化尾门的能够降低汽车风阻,从而降低油耗和电耗。
