The invention discloses a foldable variable-pitch propeller for a fixed-wing unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicles. The foldable variable-pitch propeller comprises a shell, a cavity is formed in the shell, bearings are embedded in the two sides of the shell, the bearings are symmetrically distributed relative to the shell, and the bearings are parallel to each other; propeller clamps are installed on the two sides of the shell in a matched mode, and the two sets of propeller clamps are coaxial; the two ends, close to each other, of the two setsof propeller clamps penetrate through the bearing and extend into the cavity, and clamping grooves are formed in the two ends, away from each other, of the two sets of propeller clamps in the axial direction; and blades are hinged into the clamping grooves in a matched mode. The foldable variable-pitch propeller is novel in structure and simple and reliable in structure, and the problem that thefixed-pitch blades have adverse effects on the flight performance of the fixed-wing unmanned aerial vehicle is effectively solved.

    本发明公开了一种固定翼无人机用可折叠变距螺旋桨,涉及无人机技术领域,其包括壳体,所述壳体内开设有腔体,且所述壳体的两侧均镶嵌有轴承,所述轴承关于壳体呈对称分布,且所述轴承呈互相平行状,所述壳体的两侧均匹配安装有桨夹,且两组所述桨夹呈共轴状,两组所述桨夹互相靠近的两端均贯穿于轴承并延伸至腔体内,且两组所述桨夹互相远离的两端均沿其轴向开设有夹槽,所述夹槽内均匹配铰接有桨叶。本发明结构新颖,且该装置结构简单可靠,有效的解决了固定螺距桨叶对固定翼无人机飞行性能存在不利影响的问题。
