The invention relates to a locking and unlocking device for satellite docking. The device comprises four auxiliary electromagnets (1), a passive system (2) and an active system (3), wherein the two auxiliary electromagnets and the active system (3) are fixed on the active satellite, the other two auxiliary electromagnets and the passive system (2) are fixed on the passive satellite, the auxiliaryelectromagnets (1) on the active satellite are in one-to-one correspondence with the auxiliary electromagnets of the passive satellite, and the axes of the passive system (2) and the active system (3)coincide; the passive system comprises a locking and unlocking electromagnet (5), a passive system main electromagnet (9), a sliding rail (10), a sliding block (11), a passive system shell (12), a docking sleeve and a passive docking piece (17). The driving system comprises a driving docking piece (18), a fine alignment gear sleeve, a driving system main electromagnet (21) and a driving system shell (22). The docking reliability and the docking precision are improved, and flexible docking and rigid locking are achieved.

    本发明涉及一种卫星对接的锁紧与解锁装置。该装置包括4个辅助电磁铁(1)、被动系统(2)和主动系统(3);2个辅助电磁铁和主动系统(3)固定在主动卫星上,其余2个辅助电磁铁和被动系统(2)固定在被动卫星上,主动卫星上的辅助电磁铁(1)和被动卫星的辅助电磁铁一一对应,被动系统(2)与主动系统(3)轴线重合;被动系统包括锁紧解锁电磁铁(5)、被动系统主电磁铁(9)、滑轨(10)、滑块(11)、被动系统外壳(12)、对接套和被动对接件(17);主动系统包括主动对接件(18)、精对准齿套、主动系统主电磁铁(21)和主动系统外壳(22);本发明提高对接可靠性和对接精准度,实现了柔性对接、刚性锁紧。
