The invention discloses a self-unfolding miniature propeller unmanned aerial vehicle which comprises a flight power system, an unmanned aerial vehicle body, a landing system, a folding and unfolding device, a control circuit and a battery. The flight power system comprises propellers and motors, the unmanned aerial vehicle body comprises a fuselage and a vertical fin, the landing system comprises a supporting frame and wheels, and the folding and unfolding device comprises a locking device, an unfolding device and a limiting device. When the unmanned aerial vehicle is not used, propellers in the flight power system, a vertical fin in the unmanned aerial vehicle body and a supporting frame in the landing system are all in a folded state; during use, the vertical fin and the supporting frame are automatically unfolded and fixed in a vertical state through the folding and unfolding device; and the propellers are automatically unfolded under the action of centrifugal force generated by rotation of the motor, and automatically recover to a folded state under the action of the spring after stopping rotating. According to the design, the unmanned aerial vehicle can be automatically unfolded, the folded state of the unmanned aerial vehicle saves a lot of space compared with the unfolded state, and the transportability and portability are greatly improved.

    本发明公开了一种可自展开的微型螺旋桨无人机,包括飞行动力系统、无人机主体、着陆系统、折展装置、控制电路、电池;飞行动力系统包含螺旋桨和电机,无人机主体包含机身和垂尾,着陆系统包含支撑架和轮子,折展装置包含锁扣装置、展开装置和限位装置;无人机在未使用时,飞行动力系统中的螺旋桨、无人机主体中的垂尾、着陆系统中的支撑架均处于折叠状态;使用时,通过折展装置实现垂尾、支撑架自动展开并固定在竖直状态;螺旋桨则在电机转动产生的离心力作用下自动展开,停转后在弹簧作用下自动恢复折叠状态。该设计可实现无人机自动展开,无人机折叠状态较展开状态节省大量空间,大大提高了运输性和便携性。
