At present, the wing of an unmanned aerial vehicle is generally provided with a groove for accommodating a wire along the axial direction of the wing. After the wire is installed in the groove, the groove is closed by a cover. Generally, the cover body is screwed with the groove of the wing by bolts. Therefore, for the connection of the cover body and the wing, a large amount of work of installing screws is required, and the operation is troublesome.
另外，由于机臂的分为凹槽与盖体上下两部分，再通过螺丝对凹槽与盖体进行组装。因此，机臂的强度较小，需要在机臂的内侧壁设有加强柱。加强柱会占用机臂凹槽的内部空间，影响凹槽内线材的走线空间，限制布线。In addition, since the arm is divided into a groove and a cover body, the groove and the cover body are assembled by screws. Therefore, the strength of the arm is small, and it is necessary to provide a reinforcing column on the inner side wall of the arm. The reinforcement column will occupy the internal space of the arm groove, affect the wiring space of the wire in the groove, and limit the wiring.

The plurality of arms 100 are respectively disposed around the central body 11. The plurality of power devices 12 are respectively disposed on the plurality of arms 100. The wire is guided from the flight control system in the center body 11 to the power device 12 through the arm 100, and electrically connects the flight control system and the power device 12.
请参阅图2，本实施方式的机臂100包括管状的主体110。主体110沿其轴向分为用于承载动力装置12的前臂部120及用于连接中心体11的后臂部130。前臂部120与动力装置12连接。后臂部130与中心体11固定连接。Please refer to FIG. 2, the arm 100 of this embodiment includes a tubular body 110. The main body 110 is divided along its axial direction into a forearm portion 120 for carrying the power unit 12 and a rear arm portion 130 for connecting the central body 11. The forearm portion 120 is connected to the power unit 12. The rear arm portion 130 is fixedly connected to the central body 11.
前臂部120的一端为前臂部120的自由端122，另一端为第一连接端121。前臂部120的自由端122与动力装置12连接。One end of the forearm portion 120 is a free end 122 of the forearm portion 120, and the other end is a first connection end 121. The free end 122 of the forearm portion 120 is connected to the power unit 12.
后臂部130的一端与中心体11连接，后壁的另一端为第二连接端131。前臂部120的第一连接端121与后臂部130的第二连接端131相互对插连接。因此，使得前臂部与后臂部相连通，形成用于供线材穿过的穿线通道。线材从中心体11穿入后臂部130经第一连接端121与第二连接端131进入到前臂部120，与动力装置12电连接。在上述机臂100内进行穿线，只需将线材从机臂100的穿线通道内穿过即可。无需进行大量的螺丝拆卸、安装工作，操作方便，提高安装效率。One end of the rear arm portion 130 is connected to the central body 11, and the other end of the rear wall is a second connection end 131.
