参照图3，为叶脉式两级展开太阳能电池在二级展开状态下的对应示意图。其结构主要包括薄膜单元(10)、折叠可展开结构(20)和叶脉状气路(30)。Referring to Figure 3, it is a corresponding schematic diagram of a leaf vein type two-stage unfolding solar cell in a second stage unfolding state. Its structure mainly includes a film unit (10), a foldable unfoldable structure (20) and a leaf vein shaped air path (30).
参照图4，为叶脉式两级展开太阳能电池的基本折叠结构(21)的折叠纹理示意图，图中折叠单元为和正方形单元(11)和等腰直角三角形单元(12)。4 , which is a schematic diagram of the folding texture of the basic folding structure ( 21 ) of a leaf-vein-type two-stage unfolded solar cell, wherein the folding units are a square unit ( 11 ) and an isosceles right triangle unit ( 12 ).
参照图5，为叶脉式两级展开太阳能电池的基本折叠结构(21)和折叠可展开结构(20)的整体示意图，图中，(210)为示例基本折叠结构的中心单元(回转中心)，(22)为中心单元的一顶点，(23)为与该顶点连接的峰谷线。Referring to Figure 5, it is an overall schematic diagram of the basic folding structure (21) and the foldable and expandable structure (20) of the leaf-vein type two-stage unfolding solar cell. In the figure, (210) is the central unit (rotation center) of the example basic folding structure, (22) is a vertex of the central unit, and (23) is the peak-to-valley line connected to the vertex.
参照图6，为叶脉式两级展开太阳能电池的叶脉状气路(30)分布图，叶脉状气路(30)包括连接各回转中心气路接口的中心矩形边线部分(301)和各基本折叠结构(21)中沿着中心单元(210)向四周展开的四条斜向峰谷线部分(302)。整个叶脉式气路的充气过程根据这两部分的充气顺序((301)为第一阶段充气，(302)为第二阶段充气)，对应着相应的展开状态。Referring to Fig. 6, it is a distribution diagram of the vein-shaped air path (30) of the vein-shaped two-stage unfolding solar cell. The vein-shaped air path (30) includes a central rectangular edge line portion (301) connecting each rotating central air path interface and four oblique peak-valley line portions (302) in each basic folding structure (21) that unfold to the surroundings along the central unit (210). The inflation process of the entire vein-shaped air path corresponds to the corresponding unfolding state according to the inflation sequence of these two parts ((301) is the first stage inflation, (302) is the second stage inflation).
工作原理：首先通过对中心刚性回转中心主单元(211)进行充气，该单元在得到充气后，气体沿着中心矩形边线部分(301)将气体依次传递到其他回转中心单元(212～214)，此过程中，整个太阳能电池完成一级展开；之后，随着气体不断输入，气体将沿着各回转中心向四周展开的四条斜向峰谷线部分(302)进行传输，充满对应的气路，完成刚化过程。Working principle: First, the central rigid rotation center main unit (211) is inflated. After the unit is inflated, the gas is transferred to other rotation center units (212-214) in sequence along the central rectangular edge line part (301). During this process, the entire solar cell completes the first-level expansion; thereafter, as the gas is continuously input, the gas is transmitted along the four oblique peak and valley line parts (302) that are expanded around each rotation center, filling the corresponding gas path and completing the rigidification process.
