The invention relates to an automatic attitude adjusting device for unmanned aerial vehicle landing in the field of unmanned aerial vehicle attitude control, which comprises a group of undercarriages symmetrically arranged below an unmanned aerial vehicle body, rotating frames rotationally connected with the tops of the undercarriages are nested in the undercarriages, and the upper parts of the rotating frames are connected with first motors for driving the rotating frames to rotate; a lower pressing wing rotationally connected with the side wall of the rotating frame is embedded in the rotating frame, and the lower pressing wing is connected with a second motor driving the lower pressing wing to rotate; by arranging an ultrasonic wind speed sensor and a lower pressing wing capable of being adjusted along with the change of the wind direction, transverse airflow flows through the lower pressing wing, the lower pressing wing provides downward pressure for the unmanned aerial vehicle after the unmanned aerial vehicle makes contact with the ground, and the unmanned aerial vehicle is stably pressed on the ground before and after a propeller motor is closed; the rollover damage condition of the unmanned aerial vehicle caused by crosswind airflow is reduced, stable control over the posture is achieved, and the landing safety of the unmanned aerial vehicle is improved.
本发明涉及无人机姿态控制领域的一种无人机降落用姿态自动调节装置,包括对称设置在无人机本体下方的一组起落架,起落架内嵌套有与其顶部转动连接的转动框,转动框上部连接有带动其转动的第一电机,转动框内嵌套有与其侧壁转动连接的下压翼,下压翼连接有带动其转动的第二电机;通过设有超声波风速传感器以及能够随着风向变化而调节的下压翼,横向气流流过下压翼,下压翼在无人机与地面接触后为无人机提供下压力,在螺旋桨电机关闭前和关闭后将无人机稳定的压制在地面上,降低横风气流造成无人的侧翻损坏情况,实现姿态的稳定控制,提高无人机降落的安全性。
