The invention provides an electromagnetically-driven black box throwing and separating mechanism, and the mechanism comprises ejection assemblies and actuating assemblies; the ejection assemblies andthe actuating assemblies are arranged on an adapter seat; the adapter seat is fixed to an aircraft body, the ejection assemblies are arranged in the center of the adapter seat, and the actuating assemblies are evenly arranged on the periphery of the adapter seat; the actuating assemblies compress the periphery of the black box; the ejection assembly comprises a disc spring installation base, a limiting sleeve, a disc spring guide column and a disc spring; the actuation assembly comprises a direct-acting electromagnet, a connecting part, a swing rod, an ejector rod and a rotating shaft; the direct-acting electromagnet is arranged on the outer side of the swing rod, the swing rod is in a T shape, and the horizontal part of the swing rod comprises an inclined section and a horizontal section;the inclined section is matched with the inclined face of the connecting part, the horizontal section makes contact with the side face of the ejector rod, and when the direct-acting electromagnet stretches out, the ejector rod limits swinging of the swing rod. The black box ejection device is compact in structure, the black box is pressed when an airplane flies safely, and after the airplane breaks down, the black box is thrown and ejected quickly and reliably.

    本发明提供了一种电磁驱动的黑匣子抛放分离机构,包括设置在转接座上的弹射组件和作动组件,转接座固定在飞机机体上,弹射组件设置在转接座的中心处,作动组件至少设置两组,且均匀布置在转接座的四周,作动组件压紧黑匣子的周边;弹射组件包括碟簧安装座、限位套、碟簧导柱和碟簧,作动组件包括直动电磁铁、连接件、摆杆、顶杆和转轴,直动电磁铁设置在摆杆外侧,摆杆呈T字型,摆杆的水平部分包括倾斜段和水平段,摆杆的竖直部分通过转轴安装在转接座上,倾斜段与连接件的斜面配合,水平段与顶杆的侧面接触,当直动电磁铁伸出时,顶杆限制摆杆摆动。本发明结构紧凑,飞机安全飞行时,将黑匣子压紧,飞机失事后,抛放弹射黑匣子迅速可靠。
