The invention belongs to the technical field of spaceflight, and discloses an unfolding locking device for a satellite-borne driving mechanism, the unfolding locking device comprises a first connecting piece, a second connecting piece, a positioning sliding block and a locking mechanism, the first connecting piece is inserted into the second connecting piece, the positioning sliding block is arranged on the circumferential inner wall of the second connecting piece, a first sliding groove is formed in the circumferential side of the first connecting piece, and the locking mechanism is arranged in the first sliding groove; the positioning sliding block is limited in the first sliding groove in a sliding mode, a second sliding groove is formed in the peripheral side of the first connecting piece, a limiting groove is formed in the end, close to the second connecting piece, of the second sliding groove, and the output end of the locking mechanism elastically abuts against the inner wall of the second sliding groove or elastically stretches into the limiting groove. According to the unfolding and locking device for the satellite-borne driving mechanism, the reliability of the unfolding process is improved through guide fit between a positioning sliding block and a first sliding groove, the connecting face of the locking mechanism and a limiting groove can be positioned through insertion fit between a first connecting piece and a second connecting piece, the profile precision is guaranteed, and the safety of the unfolding process is improved. And a good rigidity keeping effect can be achieved for the connection of the extensible mechanism.

    本发明属于航天技术领域,公开了一种用于星载驱动机构的展开锁定装置,包括第一连接件、第二连接件、定位滑块以及锁定机构,第一连接件插接于第二连接件内,定位滑块设置于第二连接件的周向内壁,第一连接件的周侧开设有第一滑槽,定位滑块滑动限位于第一滑槽内,第一连接件的周侧开设有第二滑槽,第二滑槽靠近第二连接件的一端设置有限位槽,锁定机构的输出端弹性抵接于第二滑槽的内壁或者弹性伸入限位槽内。用于星载驱动机构的展开锁定装置通过定位滑块与第一滑槽之间的导向配合,提高展开过程的可靠性,第一连接件与第二连接件的插接配合,能够定位锁定机构和限位槽的连接面,保障形面精度,对于可展机构的连接可以起到很好的刚度保持效果。
