The embodiment of the invention provides a novel unlocking separation mechanism, and belongs to the technical field of avionics. The novel unlocking separation mechanism specifically comprises a base,a recorder connecting seat and a spring unlocking mechanism, wherein the base is of a hollow tubular structure, one end of the base is provided with a shape memory alloy power source, and the side wall of the other end of the base is circumferentially provided with a plurality of first through holes; the recorder connecting seat is used for fixing a throwing recorder, and second through holes areformed in the positions, corresponding to the first through holes, of the side wall of the recorder connecting seat in the circumferential direction; and the spring unlocking mechanism comprises a thrust spring arranged on the outer wall of the base in a sleeving mode and a limiting steel ball used for limiting and locking the recorder connecting seat and the base. The novel unlocking separationmechanism can separate the throwing recorder from an aircraft body at the key moment of aircraft accidents, so that the throwing recorder escapes from the severe crash environment, and the survival capacity of the throwing recorder is improved.

    本公开实施例中提供了一种新型解锁分离机构,属于航空电子技术领域,具体包括底座,底座为内部中空的管状结构,底座的一端设置形状记忆合金动力源,另一端的侧壁上周向开设多个第一通孔;记录器连接座,用于固定抛放记录器,记录器连接座的侧壁上对应所述第一通孔的位置周向开设第二通孔;弹簧解锁机构,所述弹簧解锁机构包括套设在所述底座外壁的推力弹簧,以及用于将所述记录器连接座和所述底座限位锁定的限位钢珠。本发明在飞机失事的关键时刻能够将抛放记录器与飞机机体分离,使其脱离恶劣的坠毁环境,提高抛放记录器的幸存能力。
