The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to a variable-pitch unmanned aerial vehicle with fixed wings, which comprises an unmanned aerial vehicle body, rack cantilevers are symmetrically mounted at two opposite angles of the unmanned aerial vehicle body, and a power assembly is mounted at one end, far away from the unmanned aerial vehicle body, of each rack cantilever; the power assembly comprises a power mechanism and a variable-pitch mechanism, the power mechanism comprises a rotor wing, the variable-pitch mechanism comprises a fixed disc, a movable disc is arranged on the inner side of the fixed disc, a cavity is formed between the fixed disc and the movable disc, and the movable disc is connected to the rotor wing through a first connecting rod and a second connecting rod; a variable pressure mechanism is arranged at the lower part of the unmanned aerial vehicle body; fixed wings are rotationally mounted on the two sides of the unmanned aerial vehicle body; and fluid media are pumped into the cavities or pumped out of the cavities through the variable-pressure mechanisms, so that the movable disc is driven to stretch out and draw back up and down in the fixed disc, the rotor wings are driven to deflect through the movable disc, and variable-pitch adjustment of the rotor wings is achieved.

    本发明属于无人机技术领域,具体涉及一种带有固定翼的可变桨距式无人机,包括:无人机本体,所述无人机本体的两对角处对称安装有机架悬臂,所述机架悬臂远离所述无人机本体的一端安装有动力组件;所述动力组件包括有动力机构和变距机构,其中,所述动力机构包括有旋翼,所述变距机构包括有定盘,所述定盘的内侧设置有动盘,所述定盘与动盘之间形成有空腔,所述动盘通过连杆一和连杆二连接在旋翼上;所述无人机本体的下部设置有变压机构;所述无人机本体的两侧转动安装有固定翼;利用变压机构向空腔中泵入流体介质或将流体介质从空腔中抽出,从而驱动动盘在定盘中进行上下伸缩,通过动盘带动旋翼进行偏转,实现旋翼的变距调节。
