Embodiment 1
[0037] Embodiment one, combining figure 1 and figure 2 Shown:
[0038] A rotor type unmanned aerial vehicle fall protection device, comprising a body 1 and a rotor 19 arranged on the body 1, the body 1 has a front 101 and a back 102, the protection device includes a catapult 2, a high-pressure gas tank 8, an ejection opening and closing Door 11 , attitude sensor 14 and control module 15 .
[0039] There are two ejection tubes 2, and the ejection tube 2 has an opening, a side wall, an inner cavity, and a bottom of the tube. There is a top plate 3, the top plate 3 can be made of rubber material, the top plate 3 can slide axially along the catapult 2, because the top plate 3 has a certain elasticity, the top plate 3 expands tightly in the catapult 2, so that the top plate 3 and the inner wall of the catapult 2 There is a seamless sealing connection between them; wherein, the top plate 3 separates the ejection cylinder 2 into a high-pressure chamber 4 and an ejection chamber 5...
Embodiment 2
[0059] Embodiment two, such as Figure 5 Shown:
[0060] A method for protecting a rotary-wing unmanned aerial vehicle from falling out of control, comprising the steps of:
[0061] S100, detecting the attitude change data of the body 1 in real time, the attitude change data includes the inclination angle of the body 1 and the falling speed of the body 1, wherein the inclination angle of the body 1 placed horizontally with the front 101 facing upward is set to 0°;
[0062] S200, analyze the attitude change data, and judge whether the inclination angle of the body 1 and the falling speed of the body 1 are greater than a threshold, and if so, go to S300;
[0063] S300, judging whether the maintenance time of the inclination angle of the body 1 and the falling speed of the body 1 exceeds a preset time, and if so, proceed to S400;
[0064] S400, setting the threshold value of the inclination angle of the front 101 of the body 1 to ±90°, and judging the angle of the inclination a...
