The invention provides a solar wing with a large folding and unfolding ratio. The solar wing comprises an unfolding mechanism and a solar cell substrate assembly which are arranged on a satellite body. The unfolding mechanism comprises an unfolding rod assembly, a guide roller assembly and a driving rope; the unfolding rod assembly comprises a plurality of unfolding rods and a first hinge for connecting the unfolding rods to form an open-loop chain structure, the unfolding rod assembly can realize folding and unfolding, wherein when in a folding state, the side surfaces of adjacent unfolding rods abut against each other, and when in an unfolding state, the end parts of the adjacent unfolding rods abut against each other; and the guide roller assembly comprises guide rollers which are arranged at the hinged positions of the unfolding rods and coaxial with the first hinge. The solar wing with the large folding and unfolding ratio is unfolded in a rope driving mode, the number of parts and components is small, the structure is simple, the occupied space is small, the product weight is low, and mechanism reliability is high; and for different task requirements, a solar cell substrate is unfolded by different lengths by increasing or decreasing the number of the unfolding rods and the rollers without redesigning the structure.
本发明提供了大折展比太阳翼,包括设于卫星星体上的展开机构及太阳能电池基板组件;所述展开机构包括展开杆组件、导向滚轮组件和驱动绳;所述展开杆组件包括多根展开杆和将所述展开杆连接形成开环链状结构的第一铰链,所述展开杆组件可实现折叠和展开,其中,折叠状态时,相邻展开杆的侧面相抵靠,展开状态时,相邻展开杆的端部相抵靠;所述导向滚轮组件包括设于展开杆铰接处与第一铰链同轴的导向滚轮。本发明中的大折展比太阳翼通过绳驱动的方式展开,零、组件较少,结构简单,占用空间小,产品重量轻,机构可靠性较高;针对不同任务需求,可以通过增加或者减少展开杆及滚轮数量,实现展开不同长度的太阳能电池基板,无需对结构重新设计。
