The embodiment of the invention discloses a solar wing unfolding mechanism. The solar wing unfolding mechanism comprises a plurality of frame assemblies arranged in parallel and folding assemblies arranged between the adjacent frame assemblies. The two ends of the folding assembly are hinged to the two adjacent frame assemblies respectively. The folding assembly comprises two folding arms which are hinged to each other, each folding arm comprises a folding arm body, and each folding arm body is of a honeycomb sandwich structure. By adopting the folding arms with the honeycomb sandwich structures and fully utilizing the characteristic of high flexural rigidity of the honeycomb sandwich structures, the flattening design of the solar wing unfolding mechanism is realized, the enveloping space in a folding state is saved, the weight can be reduced, and the volume can be reduced. In addition, through the structural design of metal materials, the design of a light-weight and high-rigidity stretching mechanism product is achieved.
本发明实施例公开了一种太阳翼展开机构,包括若干个平行设置的框架组件以及配置于相邻框架组件之间的折叠组件;所述折叠组件的两端分别与相邻的两个框架组件铰接;所述折叠组件包括两个相互铰接的折叠臂,所述折叠臂包括折叠臂本体,所述折叠臂本体为蜂窝夹层结构。通过采用蜂窝夹层结构的折叠臂,充分利用蜂窝夹层结构抗弯刚度高的特点,实现太阳翼展开机构的扁平化设计,节省折叠状态下包络空间,既能实现重量的降低,又能保证体积减小。此外,通过金属材料的结构设计实现了轻量化、高刚度的伸展机构产品设计。
