The invention discloses an over-travel springback type stretching mechanism locking method, which is applied to a stretching mechanism of a solar wing, and comprises the following steps: S1, unfolding the stretching mechanism, and driving a solar wing array plane to be unfolded to a limit position; and S2, tension is provided for the solar wing array plane through the uniform load system for folding, the solar wing array plane is driven to be folded to the limiting point, and therefore locking is achieved. The stretching mechanism can be reliably locked after being unfolded, no extra locking device needs to be arranged, the locking function of the stretching mechanism is provided by the uniform load system, and therefore the whole structure has the high integration degree and has the great advantage in the weight aspect. In addition, the device can be applied to deployable mechanism products of various solar wings, and has the advantages of being high in practicability and wide in applicability.

    本发明公开了一种超行程回弹式伸展机构锁定方法,应用于太阳翼的伸展机构,包括如下步骤:S1:对伸展机构进行展开,带动太阳翼阵面展开至极限位置;S2:通过均载系统向太阳翼阵面提供张紧力进行收拢,带动太阳翼阵面收拢至限位点,从而实现锁定。本发明可以实现对伸展机构可靠的展开后锁定,且不需要额外设置锁定装置,其锁定功能由均载系统提供,因此整体结构具有较高的集成度,在重量方面具有较大的优势。另外本发明可以应用于各类太阳翼的可展机构产品中,实用性强,适用性广的优点。
