The invention discloses a rotary hinge device for mounting a solar panel. The rotary hinge device comprises a hinge body and a panel fixer, hinge tables are arranged at the two ends of the hinge body, connecting tables are arranged at the two ends of the sailboard fixing device, the hinge tables and the connecting tables are connected through rotating joints, so that the sailboard fixing device can rotate around the hinge tables, and the rotating joints are sleeved with hinge torsion springs matched with the hinge tables and the connecting tables. When in use, the device is fixedly mounted on the side surface of a satellite structure frame and can be reliably connected with a sailboard; and meanwhile, the rotary joint for rotationally connecting the sailboard is arranged in the hinge main body, so that the flexible rotary connection between the sailboard and the satellite body is realized, and the secondary unfolding requirement of the sailboard is met. A time sequence control structure is further arranged in the hinge to prevent interference and collision in the unfolding process, and the phenomenon of over-unfolding or under-unfolding is prevented.
本发明公开了一种太阳能帆板安装旋转铰链装置,包括铰链本体和帆板固定器;所述铰链本体两端设有铰接台,帆板固定器两端设有连接台,铰接台与连接台之间通过旋转接头连接,使帆板固定器能够绕铰接台旋转,旋转接头上套有与铰接台和连接台配合的铰链扭簧;其中一连接台外端还设有时序扭簧,本发明使用时固定安装于卫星结构架侧面能够与帆板可靠连接;同时用于转动连接帆板的旋转接头内置于铰链主体中,实现帆板与卫星本体之间的灵活旋转连接,支持帆板的二次展开需求。铰链内还设有时序控制结构防止展开过程中的干涉与碰撞,防止过展或欠展现象的发生。
