The invention provides a space unfolding mechanism. The space unfolding mechanism comprises a mounting base plate; the two elastic mounting pieces are symmetrically arranged on the mounting substrate; the flexible array surface is configured between the two elastic mounting pieces; the two elastic mounting pieces are configured to be capable of winding under the action of external force, so that the whole flexible array surface is in a vortex shape; the space unfolding mechanism further comprises a locking assembly used for being correspondingly matched with the elastic installation piece. And the locking assembly is configured to lock and position the wound elastic mounting piece, so that the flexible array plane is kept in a vortex shape. The space unfolding mechanism can achieve winding, pressing and unfolding of a space load product, and has the advantages that extra energy is not needed during unfolding, self-stiffening is achieved, and the unfolding process is reversible.
本发明提供一种空间展开机构,包括安装基板;两个对称配置于安装基板上的弹性安装件;以及配置于两个弹性安装件之间的柔性阵面;两个弹性安装件被配置为可在外力作用下卷绕,使得柔性阵面整体呈涡旋状;所述空间展开机构还包括用以与弹性安装件对应配合的锁定组件;所述锁定组件被配置为可将卷绕后的弹性安装件锁紧定位,以使得柔性阵面保持涡旋状。该空间展开机构能够实现空间载荷产品的卷绕压紧和展开,具备展开时不需额外能量、自刚化、展开过程可逆的特点。
