The invention discloses a separating and unlocking mechanism based on a rotating electromagnet and a separating and unlocking method.The separating and unlocking mechanism comprises an upper cylinder, a lower cylinder, a locking device, a rotating device, a pushing device, a driving device, a limiting pin, a loading nut and a microswitch, the lower cylinder is sleeved with the upper cylinder, the rotating device is installed on the driving device and can rotate along with the driving device, and the pushing device is installed on the lower cylinder; the locking device transversely penetrates through the upper cylinder and the lower cylinder and abuts against the rotating device, the upper cylinder and the lower cylinder are locked together, when the driving device receives a satellite separation signal, the rotating device is driven by the driving device to rotate from the abutting position to the disengaging position, abutting between the rotating device and the locking device is relieved, the locking device is disengaged from the upper cylinder, and the upper cylinder and the lower cylinder are locked together. The upper cylinder and the lower cylinder are unlocked, the upper cylinder is ejected out under the action of the pushing device, and satellite-rocket separation is completed. The problems that a satellite-rocket separation mechanism is complex in structure, high in cost, large in envelope size, heavy in weight and the like are solved.

    本发明公开了一种基于旋转电磁铁的分离解锁机构及分离解锁方法,包括上筒、下筒、锁定装置、转动装置、推动装置、驱动装置、限位销、加载螺母以及微动开关,上筒套在下筒上,转动装置安装在驱动装置上,且能够随驱动装置一起转动,锁定装置横穿上筒和下筒并与转动装置抵接,将上筒和下筒锁定在一起,当驱动装置接收到卫星分离信号时,转动装置在驱动装置的驱动下由抵接位置转动至脱离位置,解除转动装置与锁定装置的抵接,锁定装置由上筒中脱出,上筒和下筒解锁,上筒在推动装置作用下顶出,完成星箭分离。本发明解决了星箭分离机构结构复杂、成本高、包络尺寸大、质量重等难题。
