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 an inner support arm mounting piece, an outer support arm mounting piece and a locking assembly, the inner support arm mounting piece is hinged with the outer support arm mounting piece, the locking assembly is located on the opposite side of the hinged position of the inner support arm mounting piece and the outer support arm mounting piece, the locking assembly comprises a first locking assembly and an outer support arm lock catch, the outer support arm lock catch is fixedly connected with the outer support arm mounting piece, the first locking assembly comprises an inner support arm lock catch, a self-locking assembly and a swing arm, the first end of the inner support arm lock catch is used for being locked with the outer support arm lock catch, the inner support arm lock catch is hinged to the swing arm, the swing arm and the inner support arm mounting piece are arranged in a relative rotating mode, the self-locking assembly and the inner support arm mounting piece are arranged in a relative fixing mode, the self-locking assembly comprises a movable locking piece, and when the inner support arm lock catch is locked on the outersupport arm lock catch, the movable locking piece is used for locking the relative rotating angle of the swing arm and the inner support arm mounting piece. The technical effect that the occupied size of the unmanned aerial vehicle supporting arm is reduced through folding is achieved.

    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。支臂折叠机构包括内、外支臂安装件和锁定总成,内、外支臂安装件铰接,锁定总成位于内、外支臂安装件的铰接处的异侧,锁定总成包括第一锁定组件和外支臂锁扣,外支臂锁扣与外支臂安装件固定连接,第一锁定组件包括内支臂锁扣、自锁组件和摆臂,内支臂锁扣的第一端用于与外支臂锁扣锁定,内支臂锁扣铰接于摆臂上,摆臂与内支臂安装件相对旋转设置,自锁组件与内支臂安装件相对固定设置,自锁组件包括活动锁定件,当内支臂锁扣锁定在外支臂锁扣时,活动锁定件用于锁定摆臂与内支臂安装件的相对旋转角度。该申请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。
