The invention discloses a flexible hinge unfolding mechanism for a spacecraft solar array, and belongs to the field of spaceflight instruments. A flexible hinge unfolding mechanism for a spacecraft solar array comprises a connecting plate and further comprises a cross connecting rod which rotates on one side of the connecting plate through a rotating shaft, and a driving assembly is rotationally connected between the connecting plate and the cross connecting rod through the rotating shaft. The unfolding plates are arranged on the two sides of the cross connecting rod; the flexible solar panel can be stored for protection according to requirements, the situation that the impact area is easily increased due to the too large unfolding angle is prevented, meanwhile, protection oil can be sprayed in the unfolding process of the flexible solar panel, the problem that protection measures on the surface of the flexible solar panel are reduced due to long-time use is solved, the service life is further prolonged, and the practicability is high. In addition, protective oil on the surface of the flexible solar panel can be evenly scraped, the situation that the protective oil cannot be sprayed on the local surface of the flexible solar panel is avoided, and waste of the protective oil is further reduced.

    本发明公开了一种用于航天器太阳能阵列的柔性铰链展开机构,属于航天器械领域。一种用于航天器太阳能阵列的柔性铰链展开机构,包括连接板,还包括通过转轴转动在连接板一侧的交叉连杆,且连接板和交叉连杆之间通过转轴转动连接驱动组件,还包括;展开板,设置在交叉连杆的两侧;本发明本发明可以根据需求进行收纳进行保护,防止因展开的角度过大容易增大撞击的面积,同时可以对柔性太阳板展开的过程中进行喷涂保护油,防止柔性太阳板长时间使用表面的保护措施降低的问题,进一步延长了使用寿命,并且可以均匀的对柔性太阳板的表面保护油进行刮平,防止了柔性太阳板局部表面无法喷涂保护油,进一步减少了保护油的浪费。
