The invention relates to a cylindrical launching folding four-rotor unmanned aerial vehicle which comprises an upper shell, a lower shell, a front shell, a rear shell and four arms, and further comprises connecting pieces, four V-shaped springs, arm rotating shafts and inclined tables, and the four V-shaped springs, the arm rotating shafts and the inclined tables are arranged in one-to-one correspondence with the arms. According to the unmanned aerial vehicle, the vehicle arms are automatically unfolded under the cooperation of the V-shaped springs and the inclined tables and are locked under the constraint of the connecting pieces, the vehicle arm rotating shafts and one of the upper shell and the lower shell, automatic unfolding and unfolding position locking of the vehicle arms are achieved, and the safety and reliability of flight of the unmanned aerial vehicle are improved. And the unfolded vehicle arms can be quickly folded and recovered only through bare-handed operation of an operator. And the arms are X-shaped when being unfolded, so that the force transmission path is shorter, and the structural rigidity is improved. Receiving parts are machined on the arms to install the springs, and the weight of the arms is reduced. The arms are arranged in the middle of the body, the diameters of the batteries and the propellers can be larger, and the power efficiency of the unmanned aerial vehicle is improved. The electronic equipment is installed in the hollow space of the upper and lower shells, and the space utilization rate of the unmanned aerial vehicle is improved.

    本发明涉及一种筒式发射折叠四旋翼无人机,包括上机壳、下机壳、前机壳、后机壳和四个机臂,还包括连接件以及与机臂一一对应设置的四个V型弹簧、机臂转轴和斜台。机臂在V型弹簧与斜台的配合下自动展开,并且在连接件、机臂转轴以及上机壳和下机壳中的一者的约束下被锁定,实现了机臂的自动展开和展开位置锁死,提高了无人机飞行的安全性和可靠性。展开后的机臂只需要操作人员徒手操作即可快速折叠回收。机臂展开时呈X型,使传力路径更短,提高了结构刚度。机臂上加工接纳部来安装弹簧,机臂重量减轻。机臂置于机体中间部位,电池直径和螺旋桨直径可以更大,提高了无人机动力效率。电子设备安装在上下机壳的空心空间,提高了无人机空间利用率。
