The invention discloses a telescopic unfolding mechanism, comprising: a ring group, the ring group comprising a lower ring, an upper ring and a plurality of intermediate rings located between the upper ring and the lower ring, the lower ring, the intermediate rings and the upper ring being coaxially arranged; the multiple folding assemblies are arranged in the circumferential direction of the ring set at intervals and used for connecting the lower ring, the upper ring and the multiple middle rings; when the multiple folding assemblies are unfolded synchronously, all the rings in the ring set are driven to be away from one another, and the telescopic unfolding mechanism is unfolded. When the multiple folding assemblies are folded synchronously, all the rings in the ring set are driven to be close to one another, and the telescopic unfolding mechanism shrinks. The driving device is used for driving the multiple folding assemblies to be unfolded or folded synchronously. The telescopic unfolding mechanism has a large axial telescopic ratio, and the occupied space of the telescopic unfolding mechanism on aerospace equipment can be saved.

    本发明公开了一种伸缩展开机构,包括:环组,该环组包括下环、上环和位于上、下环之间的多个中间环,下环、中间环和上环同轴设置;折叠组件,数量为多个,沿着环组周向间隔设置,用于连接下环、上环和多个中间环;当多个折叠组件同步展开时,带动环组中的各环相互远离,所述伸缩展开机构展开;当多个折叠组件同步折叠时,带动环组中的各环相互靠近,所述伸缩展开机构收缩;驱动装置,用于驱动多个折叠组件同步展开或折叠。本发明具有大的轴向伸缩比,有利于节约伸缩展开机构在航空航天设备上的占用空间。
