The invention discloses a space large-scale integrated high-storage stretching mechanism, and particularly relates to the technical field of aerospace. Comprising a bearing plate, an upper center force bearing cylinder, a supporting truss, a lower center force bearing cylinder, a stacking triangular frame, a folding connecting rod, a driving hinge, a slow release assembly, a pressing rod and a firework nut, the upper center force bearing cylinder is connected between the bearing plate and the supporting truss, and the supporting truss is provided with a supporting ring; the lower central bearing cylinder is provided with a fixing plate; the folding connecting rods are rotationally connected to the stacking triangular frame, the free ends of the two folding connecting rods are rotationally connected, and the slow release assembly is used for slowly releasing the folding connecting rods; the pressing rod is arranged on the stacking triangular frame in a penetrating mode, and a disc spring is connected between the firework nut and the pressing rod. According to the technical scheme, the problem that the stretching mechanism cannot provide a bearing function or needs an additional auxiliary supporting structure when the effective load is large in mass is solved, and the small folding size, the light weight and the large unfolding and folding ratio are achieved.

    本发明专利公开了一种空间大型一体化高收纳伸展机构,具体涉及航空航天技术领域。包括承载板、上中心承力筒、支撑桁架、下中心承力筒、堆叠三角框、折叠连杆、驱动铰链、缓释组件、压紧杆和火工螺母,上中心承力筒连接在承载板与支撑桁架之间,支撑桁架设有支撑圈;下中心承力筒设有固定板;折叠连杆转动连接在堆叠三角框上,两根折叠连杆的自由端转动连接,缓释组件用于缓慢释放折叠连杆;压紧杆穿设在堆叠三角框上,火工螺母与压紧杆之间连接有碟簧。本发明技术方案解决了对于质量较大的有效载荷时,伸展机构无法的提供承载功能或者需要额外的辅助支撑结构的问题,实现了较小的收拢体积、较轻的重量和较大的展收比。
