The invention is suitable for the technical field of unmanned aerial vehicles, and provides an automatic folding mechanism for a propeller of an unmanned aerial vehicle. First limiting blocks are installed at the opposite angles of the bottom of the machine body, and first sliding plates are slidably connected to the outer portions of the two first limiting blocks in a sleeving mode. According to the automatic folding mechanism for the propeller of the unmanned aerial vehicle, the motor is arranged to drive the first gear and the second gear to rotate synchronously, the two sets of first sliding plates and second sliding plates stretch out and draw back synchronously, and therefore the propeller frame is released or retracted, and the overall occupied area of the unmanned aerial vehicle can be reduced through the folding mode; when the unmanned aerial vehicle is not used, the blades fall under the action of gravity and are attached to the side face of the mounting frame, so that the propeller blades are folded, and when the mounting frame is retracted to the side face of the vehicle body, the two sets of blades can be retracted into the containing grooves in the side face of the vehicle body, so that the blades can be protected; blade breakage caused when the unmanned aerial vehicle is carried is avoided.
本发明适用于无人机技术领域,提供了一种无人机螺旋桨自动折叠机构,包括机体;所述机体的底部对角安装有第一限位块,两组所述第一限位块的外部均滑动套接有第一滑板。本发明提供的一种无人机螺旋桨自动折叠机构,该装置通过设置电机带动上下第一齿轮与第二齿轮同步转动,而两组第一滑板与第二滑板同步伸缩,从而将螺旋桨架放出或者收回,此种折叠方式可降低无人机整体的占地面积,使无人机更易携带使用,当无人机未使用时,叶片在重力的作用下下落并贴合在安装架的侧面,以此来实现螺旋桨叶片的折叠,当安装架收回至机体的侧面时,两组叶片可收入机体侧面的放置槽中,以此可对叶片进行防护,避免无人机携带时造成叶片折断。
