The embodiment of the invention discloses a flexible solar wing constant-force tensioning mechanism which comprises a tensioning assembly fixed to a satellite cabin in a combined mode and a tensioning rope, the first end of the tensioning rope is fixedly connected with the satellite cabin through the tensioning assembly, and the second end of the tensioning rope penetrates through the end, away from the satellite cabin, of a solar wing extension arm and is fixed to the satellite cabin in a combined mode. The tensioning rope can be tensioned along with unfolding of the solar wing, and the tensioning assembly is configured to provide constant tensioning force for the tensioning rope; the tensioning assembly comprises a support fixed to the satellite cabin in a combined mode, a pull rod erected on the support and a constant force spring connected between the support and the pull rod. The first end of the tensioning rope is connected to the middle of the pull rod, and the pull rod can reciprocate relative to the support in the first direction along with stretching or shortening of the tensioning rope so as to drive the constant-force spring to stretch and deform in the first direction. Constant-force tensioning can be guaranteed in different temperature environments, the reliability of the overall design of the solar wing is improved, and the manufacturing cost is reduced.
本发明实施例公开了一种柔性太阳翼恒力张紧机构,包括结合固定于卫星舱体的张紧组件以及张紧绳,张紧绳的第一端通过张紧组件与卫星舱体连接固定,第二端穿过太阳翼伸展臂远离卫星舱体的一端并结合固定于卫星舱体,张紧绳能够随着太阳翼的展开而张紧,张紧组件被配置为对张紧绳提供恒定张紧力;张紧组件包括结合固定于卫星舱体的支架,架设于支架上的拉杆,以及连接于支架和拉杆之间的恒力弹簧;张紧绳的第一端连接于拉杆的中部,拉杆能够随张紧绳的伸长或者缩短相对于支架沿第一方向往复运动,从而带动恒力弹簧沿第一方向伸缩变形。能够在不同温度环境下保证恒力张紧,提高了太阳翼整体设计的可靠性,降低了制造成本。
