The invention discloses a flexible solar wing unfolding mechanism with a high unfolding-folding ratio. The flexible solar wing unfolding mechanism comprises a bottom plate, a shear fork rod assembly, a top plate and a solar blanket assembly; the unfolding mechanism further comprises a driving assembly integrated on the bottom plate; the driving assembly is provided with a driving motor and a transmission gear, and the transmission gear extends to the upper part of the bottom plate; and the driving assembly is in transmission connection with the shear fork rod assembly through the transmission gear and drives the shear fork rod assembly to be unfolded so as to drive the solar blanket assembly to be unfolded. The unfolding mechanism is simple in structure, high in reliability and small in mass; most structural parts in the mechanism are made of spaceflight-grade hard aluminum alloy and carbon fiber composite materials, the mechanical structure is simple and not numerous and jumbled, and the structural parts are subjected to lightweight design improvement on the premise that the strength and vibration requirements are guaranteed; and the unfolding mechanism is low in manufacturing cost and material price, structural parts are simple in structure and convenient to manufacture, the shear fork rod assembly drives the solar blanket assembly to move, and the unfolding mechanism has the advantages of being light in weight, small in folding size, large in unfolding span and high in unfolding and folding ratio.

    本发明公开了一种高展收比柔性太阳翼展开机构,包括底板、剪叉杆组件、顶板及太阳毯组件;展开机构还包括集成于底板的驱动组件;驱动组件具有驱动电机和传动齿轮,传动齿轮延伸至底板的上部;驱动组件通过传动齿轮与剪叉杆组件传动连接并驱动剪叉杆组件展开以带动太阳毯组件展开。本发明的展开机构结构简单、可靠性较高,且质量较小;机构中大部分结构件采用航天级硬质铝合金及碳纤维复合材料,机械结构简洁不庞杂,且各个结构件在保证强度及振动要求的前提下做了轻量化设计改进;本发明的展开机构制造成本较低、材料的价格较低,结构件结构简单便于制造,以剪叉杆组件带动太阳毯组件运动具有重量轻,收拢体积小,展开跨距大,展收比较高的优点。
