The invention relates to a flight power device with a blade angle self-adaptive adjustment function. The flight power device is installed in the unmanned aerial vehicle duct body and comprises a paddle supporting cylinder, paddles, a roller bearing, a brushless motor, a base and a paddle angle adjusting mechanism. The plurality of paddles are uniformly arranged on the periphery of the paddle supporting cylinder in the circumferential direction through roller bearings, and the paddle supporting cylinder and the paddles are driven by a brushless motor fixed on the base to do circular motion around the axis of the whole device; a blade inner side boss is arranged in the blade horizontal reference surface of the blade rear end surface and at the position on the same side as the blade rear edge; the blade angle adjusting mechanism drives the boss on the inner side of the blade to move up and down so as to adjust the angle of the blade. The angle of the paddle is adjusted through the paddle angle adjusting mechanism, so that the problem that the paddle angle of an existing electrically-driven unmanned aerial vehicle cannot be changed is solved, and the technical problem that the cruising ability, working noise and stability of the unmanned aerial vehicle in the flight process are affected by the environment can be solved.

    本发明为一种桨叶角自适应调节的飞行动力装置。飞行动力装置安装在无人机涵道本体内,飞行动力装置包括桨叶支撑筒,桨叶,滚子轴承,无刷电机,底座和桨叶角度调节机构;多个桨叶周向上通过滚子轴承均匀的设在桨叶支撑筒的外周,通过固定在底座的无刷电机驱动桨叶支撑筒和桨叶绕整个装置轴线做圆周运动;桨叶后端面的桨叶水平基准面内,且与桨叶后缘为同侧的位置设有桨叶内侧凸台;桨叶角度调节机构通过驱动桨叶内侧凸台上下运动实现桨叶角的调节。本发明通过桨叶角度调节机构调节桨叶的角度,从而解决了现有的电力驱动无人机桨叶角不可改变的问题,可使无人机在飞行过程中续航能力和工作噪音以及稳定性受环境影响影响的技术问题得以解决。
