The invention relates to the technical field of unmanned aerial vehicles, and discloses a multi-rotor unmanned aerial vehicle with inclined vehicle arms, the multi-rotor unmanned aerial vehicle comprises a vehicle body and a plurality of rotors, the side wall of the vehicle body is rotatably connected with the plurality of vehicle arms, the number of the vehicle arms is equal to that of the rotors, the rotors are fixedly connected with the vehicle arms, and an adjusting mechanism is arranged in the vehicle body and used for adjusting the inclination angles of the vehicle arms. The inclination angles of the arms can be adjusted through the adjusting mechanisms, when the unmanned aerial vehicle flies forwards, the arms and the rotors are inclined through the adjusting mechanisms, the arms and the rotors are inclined forwards, forward inclination of the vehicle body and inclination of the rotors are replaced, the vertical component and the horizontal component of lift force can be changed, the pitch angle of the vehicle body is reduced, and therefore the inclination angle of the vehicle body is smaller; the windward side of the unmanned aerial vehicle body is smaller, so that the wind resistance of the unmanned aerial vehicle flying forwards is effectively reduced, the flying efficiency is improved, and the problems that the wind resistance is too large and the flying efficiency is reduced due to the too large windward side of the traditional unmanned aerial vehicle when the unmanned aerial vehicle advances are solved.

    本发明涉及无人机技术领域,公开了一种机臂倾斜的多旋翼无人机,包括机体和若干旋翼,机体的侧壁转动连接有若干根机臂,且机臂数量与旋翼数量相等,旋翼与机臂固接,机体内设置有调节机构,调节机构用于调节机臂的倾角,通过调节机构能够对机臂的倾角进行调节,当无人机向前飞时,通过调节机构使机臂以及旋翼倾斜,使机臂以及旋翼前倾,替代机体前倾,旋翼倾斜,可以改变升力的垂直分量和水平分量,减少机身的俯仰角,从而使机体的倾斜角度更小,机体迎风面更小,有效的减小了无人机向前飞的风阻,从而提高了飞行效率,解决了传统无人机前进时无人机的迎风面过大导致风阻过大,飞行效率降低的问题。
