The invention discloses an unmanned aerial vehicle with the falling self-protection function; the unmanned aerial vehicle comprises a vehicle body and rotor wings, cavities are symmetrically formed in the inner wall of the vehicle body, vibration parts are fixedly connected to the inner walls of the cavities, a groove is formed in the inner wall of the top of the vehicle body, and a thermal expansion ball is elastically connected to the inner wall of the groove through a spring; a heating cavity is formed in the inner wall of the groove, a metal core rod is fixedly connected in the heating cavity, an electrified coil is wound on the side wall of the metal core rod, a sliding cavity is formed in the inner wall of the bottom of the vehicle body, a plurality of piezoelectric ceramics are symmetrically and fixedly connected to the inner wall of the sliding cavity, and a power component is slidably connected in the sliding cavity in a sealed mode. The unmanned aerial vehicle has the advantages that by arranging the thermal expansion ball, the metal core plate, the electrified coil and other structures, under the action of the spring, the expanded thermal expansion ball extends out of the vehicle body, on one hand, the falling speed of the vehicle body can be reduced, and on the other hand, when the vehicle body makes contact with the ground, the thermal expansion ball abuts against the ground, and the good buffering protection effect is achieved.

    本发明公开了一种具有坠落自保护功能的无人机,包括机体和旋翼,所述机体内壁对称开设有空腔,所述空腔内壁固定连接有振动部件,所述机体的顶部内壁开设有凹槽,所述凹槽的内壁通过弹簧弹性连接有热膨胀球,所述凹槽的内壁开设有加热腔,所述加热腔内固定连接有金属芯棒,所述金属芯棒侧壁绕设有通电线圈,所述机体的底部内壁开设有滑腔,所述滑腔内壁对称固定连接有多个压电陶瓷,所述滑腔内密封滑动连接有动力部件。优点在于:通过设置热膨胀球、金属芯板和通电线圈等结构,在弹簧的作用下,膨胀后的热膨胀球伸出机体外界,一方面可以降低机体坠落速度,另一方面可在机体与地面接触时,热膨胀球和地面相抵,起到较好的缓冲保护作用。
