The invention relates to the technical field of spacecrafts, and discloses a spacecraft interstage unlocking device and a spacecraft, the spacecraft interstage unlocking device comprises a protection cover, and the protection cover is connected with a first cabin section; the connecting piece penetrates through the second cabin section in a limiting manner and movably penetrates through the first cabin section and the top surface of the protective cover; a limiting groove is formed in the side wall of one end, extending into the protective cover, of the connecting piece; the locking mechanism is arranged in the protective cover and comprises a lock hook and a lock piece, the lock hook is rotationally connected to the inner wall of the protective cover, one end of the lock hook is bent to form a hook part, the lock piece is movably arranged in the protective cover and has a locking position and an unlocking position, and when the lock piece is located at the locking position, the lock piece abuts against the lock hook to limit rotation of the lock hook; when the lock piece is located at the unlocking position, the lock piece is separated from the second cabin section along with the first cabin section, and the connecting piece moves along with the second cabin section and drives the lock hook to rotate till the hook part is separated from the limiting groove. The spacecraft comprises the spacecraft interstage unlocking device. And testability is achieved, and the using impact force is low.

    本发明涉及航天器技术领域,公开一种航天器级间解锁装置及航天器,航天器级间解锁装置包括保护罩,保护罩与第一舱段连接;连接件限位穿过第二舱段并活动穿过第一舱段和保护罩的顶面,连接件伸入保护罩内的一端侧壁设置有限位槽;锁紧机构设置在保护罩内,锁紧机构包括锁钩和锁件,锁钩转动连接在保护罩的内壁,锁钩的一端弯折形成有钩部,锁件可移动设置在保护罩内,并具有锁紧位置和解锁位置,锁件位于锁紧位置时,锁件抵接于锁钩,以限制锁钩转动,且钩部插接于限位槽中,锁件位于解锁位置时,随第一舱段和第二舱段分离,连接件随第二舱段移动并带动锁钩转动至钩部脱离限位槽。航天器包括上述航天器级间解锁装置。具有可测性,使用冲击力较低。
