The invention discloses a high-rigidity stretching supporting device which comprises two or more stages of sleeves, a driving mechanism, a locking mechanism and a stretching state indicating device. When the locking mechanism is unlocked, the current sleeve and the inner primary sleeve are locked; the driving mechanism drives the inner-stage sleeve to be unfolded, when the front-stage sleeve is unfolded in place, the locking mechanism locks the front-stage sleeve, the front-stage sleeve and the outer-stage sleeve are locked, the front-stage sleeve and the inner-stage sleeve are unlocked, and the inner-stage sleeve is unfolded stage by stage; when the front sleeve is unfolded in place, the unfolding state indicating device is triggered to feed back an in-place signal, and the unfolding state of the sleeve at the moment is obtained. The main body sleeve structure of the stretching support device can be used as an unfolding part to realize folding, storage, unfolding and the like under a small envelope volume, and the stretching support device has high unfolding rigidity.

    本发明公开了一种高刚度伸展支撑装置,包括两级以上套筒、驱动机构、锁定机构及展开状态指示装置;锁定机构解锁时,当前套筒与内一级套筒锁定;驱动机构带动内级套筒展开,当前套筒展开到位时,锁定机构锁定,当前套筒与外一级套筒锁定,当前套筒与内一级套筒解锁,逐级展开内级套筒;当前套筒展开到位时,触发展开状态指示装置反馈到位信号,得到此时套筒的展开状态。本发明能够将伸展支撑装置的主体套筒结构作为展开部件实现在较小包络体积下的收拢、存储和展开等,且具备较高的展开刚度。
