The invention discloses a rotor soft protection device for a multi-rotor unmanned aerial vehicle. The rotor soft protection device structurally comprises an upper inflatable soft protection half ring, a lower inflatable soft protection half ring, an upper protection half ring connecting frame, a lower protection half ring connecting frame and a fuselage connecting support. The up-down inflatable soft protection half ring is composed of two hollow plastic half rings. The plastic half ring is thin in wall thickness and can be filled with hydrogen or air, and the buffering effects of the soft protection ring are different when the inflation air pressure is different. The upper and lower protective ring connecting frame is composed of upper and lower semicircular frames, a middle connecting rod and a semicircular clamping groove. The machine body connecting support is composed of an inclined connecting rod, a mounting support, a connecting bolt and a nut. And the mounting bracket is clamped into the tail end of the rotor wing arm and is fixed on the rotor wing arm through the bolt connecting piece. The rotor wing soft protection devices are installed on all rotor wing arms of the multi-rotor wing unmanned aerial vehicle. When the rotor wing soft protection device collides with other objects, the inflatable protection half rings make contact with the collided objects, the effect of protecting the rotor wings and the good buffering effect are achieved, and the lift force of the unmanned aerial vehicle can be improved when the protection half rings are inflated with hydrogen.
本发明公开了一种多旋翼无人机旋翼软体防护装置,其结构包括上下充气式软体防护半圈、上下防护半圈连接架和机身连接支架。上下充气式软体防护半圈是由两个中空的塑料半圈组成。塑料半圈壁厚较薄,可充氢气或空气,充气气压不同,软体防护圈的缓冲效果不同。上下防护圈连接架由上下半圆形框、中间连接杆和半圆形的卡槽组成。机身连接支架由斜连接杆、安装支架、连接螺栓和螺母组成。安装支架卡入旋翼臂末端,并通过螺栓连接件固定于旋翼臂。旋翼软体防护装置安装在多旋翼无人机的各个旋翼臂上。当旋翼软体防护装置与其他物体碰撞时,充气式防护半圈接触碰撞物体,具有保护旋翼的作用和较好的缓冲效果,防护半圈充入氢气时还能提高无人机的升力。
