The invention discloses a solar wing unfolding mechanism, a power supply device and a spacecraft, and the solar wing unfolding mechanism comprises a base; the unfolding assembly comprises an unfolding rod system and an elastic driving part, one end of the unfolding rod system is connected with the base, and the elastic driving part is arranged on the unfolding rod system; the substrate connecting piece is arranged at one end, far away from the base, of the unfolding rod system; the speed regulation assembly is arranged on the base and is matched with the unfolding rod system in a speed regulation manner; wherein the elastic driving piece is used for driving the unfolding rod system to be unfolded by means of the elastic force of the elastic driving piece so that the base plate connecting piece can move in the direction away from the base, and the speed adjusting assembly is used for providing balance force for the unfolding rod system in the unfolding process of the unfolding rod system. The solar wing unfolding mechanism can solve the problems that when the unfolding rod system reaches the maximum unfolding position, large impact can be generated, and large negative effects can be generated on related components and spacecrafts.
本发明公开了一种太阳翼展开机构、供电装置以及航天器,太阳翼展开机构,包括:底座;展开组件,展开组件包括展开杆系以及弹性驱动件,展开杆系的一端与底座连接,弹性驱动件设置于展开杆系上;基板连接件,基板连接件设置于展开杆系远离底座的一端;调速组件,调速组件设置于底座上,并与展开杆系调速配合;其中,弹性驱动件用于依靠其自身的弹力驱动展开杆系展开,以使基板连接件朝远离底座的方向移动,调速组件用于在展开杆系展开过程中为展开杆系提供平衡力。上述的太阳翼展开机构可以解决当展开杆系在到达最大展开位置时会产生较大的冲击,对与之相关的构件及航天器都会产生较大的负面影响的问题。
