The invention belongs to the technical field of unmanned aerial vehicles, and relates to a multi-rotor unmanned aerial vehicle with arms capable of being automatically folded, the multi-rotor unmanned aerial vehicle comprises an upper cover, mounting seats are mounted at four corners of the top of the upper cover, folding arms are arranged on the four mounting seats, lead screws are rotatably connected to the interiors of the mounting seats, and the lead screws are arranged in the horizontal axis direction of the mounting seats; two connected threaded sections are arranged on the lead screw, the rotation directions of the two threaded sections are the same, the thread pitch of the threaded section away from the middle of the machine body is equal, and the thread pitch of the other threaded section is gradually reduced in the direction close to the middle of the machine body; the first sliding block and the second sliding block are slidably connected to the interior of the mounting base, the end of the folding arm is rotationally arranged on the first sliding block, and the end of the folding arm is clamped and matched with the second sliding block. The unmanned aerial vehicle has the advantages that the folding arms are moved towards the middle of the vehicle body firstly and then rotated upwards, so that the wings are erected upwards, and folding is more thorough.
本发明属于无人机技术领域,涉及一种机臂可自动折叠的多旋翼无人机,包括上盖,所述上盖顶部的四角处均安装有安装座,四个安装座上均设置有折叠臂,所述安装座的内部转动连接有丝杠,丝杠沿安装座的水平轴线方向布设,丝杠上设置有两个相连的螺纹段,两个螺纹段的旋转方向相同,其中远离机身中部的一个螺纹段的螺距相等,另一个螺纹段的螺距随着朝靠近机身中部的方向而逐渐减小,所述丝杠上依次套设有第一滑块和第二滑块,第一滑块和第二滑块均滑动连接于安装座的内部,折叠臂的端部转动设置在第一滑块上,折叠臂的端部与第二滑块卡接配合。优点在于:首先向机身的中部移动折叠臂,移动后再向上转动折叠臂,使机翼向上竖起,使折叠更加彻底。
