The invention relates to a spacecraft parking mechanism, and belongs to the field of space station cargo transportation. The spacecraft parking mechanism comprises an active end and a passive end. Theactive end comprises a three-jaw connecting mechanism, a spring push rod separation mechanism, a ball screw transmission mechanism, a worm and gear self-locking mechanism, an active end shell, an active end electric interface, a push disc and a fixed disc; the passive end comprises a passive end shell, a passive end disc spring assembly, a passive end electric interface and a passive end guide directional hole; after the active end is aligned with the active end under the driving of the space mechanical arm, the three-jaw connecting mechanism is rotated outwards to be opened; the active end continues to move towards the driven end until the active end electric interface is inserted into the passive end electric interface and is inserted in place; three clamping jaws of the three-jaw connecting mechanism rotate inwards to be closed, and locking and fixing are achieved. Mechanical connection between carried goods and a space station can be achieved under the assistance of the space mechanical arm, the goods can be parked in the space station, and stable parking can be kept for a long time. When separation is needed, low-impact reliable separation is realized.

    本发明涉及一种航天器停泊机构,属于空间站货物运输领域;包括主动端和被动端;主动端包括三爪式连接机构、弹簧推杆分离机构、滚珠丝杠传动机构、蜗轮蜗杆自锁机构、主动端壳体、主动端电接口、推盘和固定盘;被动端包括被动端壳体、被动端碟簧组件、被动端电接口和被动端导引定向孔;主动端在空间机械臂带动下对准被动端后;三爪式连接机构向外旋转打开;主动端继续向被动端移动;直至主动端电接口插入被动端电接口,直至插接到位;三爪式连接机构的3个夹爪向内旋转关闭,现锁紧固定;本发明能够在空间机械臂协助下实现携带货物与空间站机械连接,能够将货物停靠在空间站,并能长期保持稳定停靠。在需要分离时,实现低冲击可靠分离。
