The invention relates to the technical field of unmanned aerial vehicles, and particularly relates to a support arm folding mechanism, an unmanned aerial vehicle support arm and an unmanned aerial vehicle. The support arm folding mechanism comprises a first support arm connecting piece, a second support arm connecting piece and a locking assembly, wherein the first support arm connecting piece isrotationally connected with the second support arm connecting piece, the locking assembly is located on the opposite side of the rotary connecting position of the first support arm connecting piece and the second support arm connecting piece, the locking assembly comprises a first limiting assembly and a second limiting assembly, the second limiting assembly is fixedly connected with the second support arm connecting piece, the first limiting assembly comprises a first locking piece and a rocker arm, the first locking piece is rotationally connected to the rocker arm, the rocker arm and the first support arm connecting piece are arranged in a relative rotating mode, a second locking piece is detachably connected to the first locking piece, and when the first locking piece is locked to thesecond limiting assembly, the second locking piece is used for locking the relative rotating angle of the first locking piece and the rocker arm. The problem that transportation is inconvenient due tothe fact that the size of the unmanned aerial vehicle is increased is solved, and the technical effect that the occupied size of the unmanned aerial vehicle support arm is reduced through folding isachieved.

    本发明涉及无人机的技术领域,尤其涉及一种支臂折叠机构、无人机支臂和无人机。支臂折叠机构包括第一、二支臂连接件和锁合组件,第一、二支臂连接件转动连接,锁合组件位于第一、二支臂连接件的转动连接处的异侧,锁合组件包括第一、二限位组件,第二限位组件与第二支臂连接件固定连接,第一限位组件包括第一锁合件和摇臂,第一锁合件转动连接于摇臂上,摇臂与第一支臂连接件相对转动设置,第一锁合件上可拆卸连接有第二锁合件,当第一锁合件锁合在第二限位组件时,第二锁合件用于锁定第一锁合件与摇臂的相对转动角度。该申请解决了无人机体积增大而导致运输不便的问题,实现了通过折叠来缩小无人机支臂的占用体积的技术效果。
