The invention relates to an unlocking principle redundant annular effective load separating mechanism. The mechanism comprises a belt body, a motor driving unlocking assembly and a fire work point type connecting and separating device. During installation, flanges of a payload lower end frame and a payload support upper end frame are embedded into V-shaped grooves of the belt body, a protruding connecting structure is arranged on the outer side of the end of the belt body, the connecting structure is connected in series through a motor driving unlocking assembly and a firing point type connecting and separating device, the belt body is stretched, and the end of the belt body is folded; the belt body hoops and is connected with the effective load lower end frame and the effective load bracket upper end frame; the motor-driven unlocking assembly adopts a motor-driven mechanical limiting relieving principle to realize unlocking; the pyrotechnic point type connection and separation device is unlocked by adopting a pyrotechnic point explosion structure damage principle; the motor drives any one of the unlocking assembly and the fire work point type connecting and separating device to be unlocked normally, the belt body contracts in the annular direction and expands outwards in the radial direction, and separation of the effective load lower end frame and the effective load support upper end frame is completed.

    本发明涉及一种解锁原理冗余的环形有效载荷分离机构,该机构包括带体、电机驱动解锁组件、火工点式连接分离装置;安装时,有效载荷下端框、有效载荷支架上端框的凸缘嵌入带体V形槽内,带体的端头外侧设置突出的连接结构,连接结构采用电机驱动解锁组件和火工点式连接分离装置串联方式连接,拉伸带体并将带体端头收拢,带体箍紧并连接有效载荷下端框、有效载荷支架上端框;电机驱动解锁组件采用电机驱动解除机械限位原理实现解锁;火工点式连接分离装置采用火工点爆结构破坏原理实现解锁;电机驱动解锁组件、火工点式连接分离装置两者中任意一个正常解锁,带体沿环向收缩并沿径向向外扩张,完成有效载荷下端框、有效载荷支架上端框分离。
