The invention relates to the technical field of hinges for spacecrafts, in particular to a miniature unfolding hinge mechanism and a spacecraft. The hinge mechanism comprises a fixed hinge, a movable hinge assembly, a torsion spring and an anti-rebound assembly. The movable hinge assembly is connected with the fixed hinge through a torsional spring, and the torsional spring can enable the movable hinge assembly to rotate relative to the fixed hinge; the movable hinge assembly comprises a first movable hinge; the first movable hinge is inserted into the fixed hinge, and the two end faces of the second arc-shaped boss of the first movable hinge can abut against or be separated from the two end faces of the first arc-shaped boss on the fixed hinge correspondingly. The anti-springback assembly comprises a reed arranged on the fixed hinge; when the first movable hinge is in a first state, the reed is attached to the outer surface of the second arc-shaped boss; when the first movable hinge rotates to a second state, the side edge of the reed abuts against one end face of the second arc-shaped boss, and the first movable hinge can be prevented from rotating reversely. The hinge mechanism is compact in structure and easy to disassemble and assemble, and can be unfolded under the action of elastic potential energy and locked and positioned at a set position.
本申请涉及航天器用铰链技术领域,特别涉及一种微型展开铰链机构及航天器。所述铰链机构包括定铰、动铰组件、扭簧和防回弹组件;动铰组件与定铰之间通过扭簧连接,扭簧能够使动铰组件相对于定铰旋转;动铰组件包括第一动铰;第一动铰插设于定铰上,且使得第一动铰的第二弧形凸台的两个端面能够分别与定铰上的第一弧形凸台的两个端面抵接或分离;防回弹组件包括设置于定铰上的簧片;在第一动铰处于第一状态时,簧片贴靠于第二弧形凸台的外表面;在第一动铰旋转至第二状态时,簧片的侧边缘抵靠于第二弧形凸台的一个端面上,并能阻止第一动铰反向旋转。该铰链机构结构紧凑,拆装简单,能够在弹性势能的作用下展开并在设定位置被锁止定位。
