The invention relates to a light and small multi-layer unfoldable thin film light shield based on a composite material hinge. The light and small multi-layer unfoldable thin film light shield is composed of the composite material hinge, a lens ring, a thin film and the like. A compression load is applied to the light shield, the composite material hinge deforms and stores strain energy, and the folding function of the light shield is achieved; and when the external compression load is removed, the strain energy stored by the composite material hinge can enable the light shield to quickly recover to the initial configuration, so that the unfolding function of the film light shield is realized. The mechanism is simple in structure, low in cost, small in overall mass, small in size after being folded, high in rigidity and high in reliability, and can provide stable optical and thermal environments for an optical system.
本发明是一种基于复合材料铰链的轻小型多层可展开式薄膜遮光罩,由复合材料铰链、镜环、薄膜等部分组成。对遮光罩施加压缩载荷,复合材料铰链产生变形储存应变能,实现遮光罩的折叠功能;当撤去外部压缩载荷时,复合材料铰链储存的应变能将使遮光罩迅速恢复至初始构型,实现薄膜遮光罩展开功能。本发明的结构简单、成本低、整体质量小、折叠后体积小、刚度大、可靠性高,能够为光学系统提供稳定的光学、热学坏境。
