The invention discloses an unmanned aerial vehicle arm folding structure which comprises a motor, a first gear and a plurality of arm folding assemblies, an output shaft of the motor is fixedly connected with the axis of the first gear, and the arm folding assemblies are evenly distributed in the circumferential direction of the first gear; the arm folding assembly comprises a gear transmission assembly, a belt transmission assembly and a connecting piece, one end of the connecting piece is connected to a belt of the belt transmission assembly, the other end of the connecting piece is fixedly connected with the end of the unmanned aerial vehicle arm, and the first gear drives the belt transmission assembly to operate through the gear transmission assembly. Therefore, the vehicle arms extend out of or are stored in the unmanned aerial vehicle body in the running direction of the belt. The first gears can act on the multiple unmanned aerial vehicle arms at the same time, so that the multiple unmanned aerial vehicle arms are folded or unfolded at the same time, and the folding or unfolding length is consistent.

    本发明公开了一种无人机机臂折叠结构,包括电机、第一齿轮以及多个机臂折叠组件,电机输出轴与第一齿轮轴心固定连接,多个机臂折叠组件沿第一齿轮圆周方向均匀分布;机臂折叠组件包括齿轮传动组件、皮带传动组件以及连接件,连接件一端连接在皮带传动组件的皮带上,另一端与无人机机臂端部固定连接,第一齿轮通过齿轮传动组件带动皮带传动组件运行,从而使得机臂沿着皮带运行的方向伸出或收纳至无人机机身中。本发明可以通过第一齿轮同时对多个无人机机臂作用,使得多个机臂同时折叠或展开,并且折叠或展开的长度一致。
