The invention discloses a low-impact self-locking space hinge mechanism, and relates to the technical field of spaceflight, and the low-impact self-locking space hinge mechanism is characterized by comprising an upper hinge, a lower hinge and a rotary liquid damper, the side wall of the upper hinge is provided with two rotating arms, a center shaft is arranged in the two rotating arms in a penetrating mode, one end of the center shaft is provided with an adjusting disc, and the adjusting disc is connected with the lower hinge; the center shaft is sleeved with a torsional spring, one end of the torsional spring is arranged in the rotating arm, the other end of the torsional spring is arranged in the adjusting disc, a coupler is arranged at the other end of the center shaft, and the coupler is connected with the center shaft and the output end of the rotary liquid damper. The low-impact self-locking space hinge mechanism has the characteristics of integrating self-driving, self-locking, low impact, small size, no energy consumption, no leakage in orbit, high reliability and the like, so that the problems of high unfolding speed, large in-place impact and the like due to the fact that an unfolding mechanism does variable-acceleration motion in the unfolding process in the prior art are solved.

    本发明公开了一种低冲击自锁定空间铰链机构,涉及航天技术领域,其技术方案要点是:包括上铰链、下铰链以及旋转式液体阻尼器,上铰链的侧壁设置有两个转动臂,两个转动臂的内部贯穿设置有中心轴,中心轴的一端部设置有调整盘,中心轴上套接设置有扭簧,扭簧的一端部设置于转动臂的内部,扭簧的另一端部设置于调整盘的内部,中心轴的另一端部设置有联轴器,联轴器连接中心轴与旋转式液体阻尼器的输出端连接。本发明的低冲击自锁定空间铰链机构具有集自驱、自锁、低冲击、体积小,无需耗能,在轨无泄漏可靠性高等特点,以解决现有技术中在展开过程中,展开机构做变加速度运动,存在展开速度快,到位冲击大等问题。
