The invention relates to a satellite hinge unfolding device. The satellite hinge unfolding device comprises a hinge module connected with a fixed side and a movable side of a satellite structure. The hinge module comprises a hinge fixed end connected with the fixed side of the satellite structure and a hinge movable end connected with the movable side of the satellite structure and rotationally connected with the hinge fixed end. Under the condition that the hinge movable end rotates to a preset angle, a sliding pin arranged in the hinge fixed end pops up towards the direction where the hinge movable end is located, and the hinge movable end is prevented from rebounding in the mode that the end of the sliding pin stretches into a bayonet of a rotary disc arranged at the hinge movable end. And a limiting screw arranged at the movable end of the hinge prevents the movable end of the hinge from continuously rotating in a manner that the limiting screw is propped against the fixed end of the hinge. According to the satellite hinge unfolding device, by arranging the sliding pin and the limiting screw, the functions of preventing the movable end of the hinge from rebounding and excessively rotating are achieved, the fault tolerance of self-locking is improved, and the problem that self-locking fails due to the fact that the sliding pin cannot pop out in time due to the fact that a satellite structure is unfolded too fast is solved.

    本发明涉及一种卫星铰链展开装置,包括与卫星结构固定侧和活动侧连接的铰链模块。铰链模块包括与卫星结构固定侧连接的铰链固定端以及与卫星结构活动侧连接且与铰链固定端转动连接的铰链活动端。在铰链活动端转动至预设角度的情况下,设置于铰链固定端中的滑销向着铰链活动端所在的方向弹出,并以端部伸入设置在铰链活动端的转盘的卡口的方式阻止铰链活动端回弹,且设置于铰链活动端的限位螺钉以其与铰链固定端抵接的形式阻止铰链活动端继续转动。本发明的卫星铰链展开装置通过设置滑销和限位螺钉分别实现了防止铰链活动端回弹和过度旋转的功能,提高了自锁的容错,避免了卫星结构展开过快导致的滑销无法及时弹出进而自锁失败的问题。
