The invention provides a damping unfolding locking joint with on-orbit adjustable unfolding speed and a spacecraft, and relates to the field of spacecraft structures and mechanisms. The damping unfolding locking joint comprises a first double-wing driving constant-torque unfolding hinge, a rotary damping mechanism and a second double-wing driving constant-torque unfolding hinge, the first double-wing driving constant-torque unfolding hinge, the rotating damping mechanism and the second double-wing driving constant-torque unfolding hinge are connected to the unfolding structure, and spherical rotating pairs of the first double-wing driving constant-torque unfolding hinge and the second double-wing driving constant-torque unfolding hinge form an unfolding locking joint rotating shaft. A rotating shaft of the unfolding locking joint is coaxial with a rotating shaft of the rotating damping mechanism. The damping unfolding locking joint with the on-orbit adjustable unfolding speed has the beneficial effects that the system is simplified, the on-orbit adjustable unfolding speed is achieved, and the locking impact is small, and better application adaptability and expansibility are achieved.

    本发明提供了一种涉及航天器结构与机构领域的展开速度在轨可调的阻尼展开锁定关节及航天器,包括第一双翼驱动恒扭矩展开铰链、转动阻尼机构以及第二双翼驱动恒扭矩展开铰链,第一双翼驱动恒扭矩展开铰链、转动阻尼机构以及第二双翼驱动恒扭矩展开铰链分别连接于展开结构上,第一双翼驱动恒扭矩展开铰链和第二双翼驱动恒扭矩展开铰链的球形转动副形成展开锁定关节转轴,展开锁定关节转轴与转动阻尼机构的转轴同轴。本发明提出的展开速度在轨可调的阻尼展开锁定关节,具有系统精简、展开速度在轨可调、锁定冲击小等有益效果,具有更好的应用适应性和拓展性。
