The invention discloses a large-area flexible solar cell wing capable of being secondarily unfolded step by step. The large-area flexible solar cell wing comprises a lifting mechanism, a stretching mechanism, a secondary unfolding flexible solar cell array, a pressing and releasing device and a box unfolding and locking mechanism. The two secondary unfolding flexible solar cell arrays are arranged at the two ends of the top of the stretching mechanism respectively, and the box body unfolding locking mechanism is arranged at the connecting position of the secondary unfolding flexible solar cell arrays and the stretching mechanism for connection. The top of the lifting mechanism is connected with the bottom of the stretching mechanism; the stretching mechanism and the secondary unfolding flexible solar cell array are respectively provided with a plurality of pressing points, the pressing and releasing devices are respectively arranged at the corresponding pressing points, and pressing force is applied to the pressing points to press the stretching mechanism and the secondary unfolding flexible solar cell array. The flexible solar cell wing has the advantages of being small in folding envelope, capable of being unfolded step by step, large in unfolding area and stable in unfolding configuration, and is suitable for a high-power spacecraft platform with a high load requirement or a high control requirement.

    本发明公开了一种可分步二次展开的大面积柔性太阳电池翼,包括:抬升机构、伸展机构、二次展开柔性太阳电池阵、压紧释放装置和箱体展开锁定机构;两个二次展开柔性太阳电池阵分别设置在伸展机构的顶部两端,二次展开柔性太阳电池阵与伸展机构的连接位置处设置有箱体展开锁定机构连接;抬升机构的顶部与伸展机构的底部连接;伸展机构和二次展开柔性太阳电池阵上分别设置有多个压紧点,各压紧释放装置分别设置在相应的压紧点位置处,通过在压紧点处施加压紧力,实现对伸展机构和二次展开柔性太阳电池阵的压紧。本发明所述柔性太阳电池翼具有收拢包络小、可分步展开、展开面积大、展开构型稳定的优点,适用于载荷要求高或控制要求高的大功率航天器平台。
