A novel unmanned aerial vehicle frame comprises a fixing frame and vehicle arms, the vehicle arms are distributed on the periphery of the fixing frame and fixedly connected with the fixing frame, thevehicle arms comprise two short vehicle arms, the two short vehicle arms are located on the same axis and located on the two sides of the fixing frame respectively, the two sides of each short vehiclearm are each provided with a long vehicle arm, and the inner ends of the long vehicle arms are close to the inner ends of the corresponding short vehicle arms; the aircraft arms are located in the same plane, the diameter of the same circle where propeller fixing points on the short aircraft arms are located is smaller than that of the same circle where the propeller fixing points on the long aircraft arms are located, and the distances between propeller faces of propellers installed on the adjacent aircraft arms are the same. The short vehicle arms and the long vehicle arms are combined, sothat the long vehicle arms are folded towards the ends of the inner ends of the short vehicle arms, and after the short vehicle arms are folded downwards, the folded frame is small in overall structure and convenient to store; after the long vehicle arms are arranged on the two sides of each short vehicle arm, the distances between the propeller faces, provided with the propellers, of the adjacentvehicle arms are the same, and the flight control requirement is met while it is guaranteed that the large-load capacity is achieved.
一种新型无人机机架,包括固定架和机臂,机臂分布在固定架四周且与固定架固定连接,机臂包括两根短机臂,两根短机臂位于同一轴线上且分别位于固定架的两侧,每根短机臂的两侧均设有一根长机臂,长机臂的内端端头靠近与其相应短机臂的内端端头;机臂位于同一平面内,短机臂上螺旋桨固定点所在同一圆的直径小于长机臂上螺旋桨固定点所在同一圆的直径,相邻机臂上安装螺旋桨的桨面之间的距离相同。将短机臂和长机臂结合设置,使得长机臂向短机臂内端端部折叠,同时短机臂向下折叠后,折叠后机架整体结构较小,便于收纳;在每根短机臂两侧设置长机臂后,相邻所述机臂上安装螺旋桨的桨面之间的距离相同,保证具有大载重能力的同时满足飞控的要求。
