The invention relates to the technical field of unmanned aerial vehicles, and provides a pneumatic ejection foldable unmanned aerial vehicle self-locking device and method.The device comprises a locking baffle, a locking connecting piece, a locking support, a button connecting piece, a button support and a locking button. The locking baffle is used for limiting an unmanned aerial vehicle arm, the locking connecting piece is connected with the locking baffle and the button connecting piece, and meanwhile, the locking connecting piece is connected with the locking support to form a rotating pair; the button connecting piece penetrates through the button support and is connected with the two locking connecting pieces; the button support is coaxially assembled with the locking button, the machine body connecting piece and the locking stand column and connected with the machine body connecting piece through a bolt. A threaded hole is formed in the middle of the machine body connecting piece and fixedly connected with the locking stand column through threads. Two working modes of the self-locking mechanism are realized by adjusting the position of the locking button: when the locking button is in a relaxed state, the arm self-locking function can be realized by folding the arm; when the locking button is in a locking state, the vehicle arms can be automatically unfolded under the action of the springs.

    本发明涉及无人机技术领域,提供了一种气动弹射可折叠无人机自锁装置及方法,该装置包括锁紧挡板、锁紧连接件、锁紧支座、按钮连接件、按钮支座及锁紧按钮。锁紧挡板用于无人机机臂限位,锁紧连接件连接锁紧挡板与按钮连接件,同时与锁紧支座连接并形成转动副;按钮连接件穿过按钮支座,与两个锁紧连接件相连接;按钮支座与锁紧按钮、机身连接件、锁紧立柱同轴装配,且通过螺栓与机身连接件连接;机身连接件中部开有螺纹孔,与锁紧立柱通过螺纹连接固结。本发明通过调节锁紧按钮的位置,实现自锁机构的两种工作模式:当锁紧按钮处于放松状态时,通过折叠机臂可实现机臂自锁功能;当锁紧按钮处于锁紧状态时,机臂可在弹簧作用下自动展开。
