Protecting device for unmanned aerial vehicle falling preventing

Abstract

The invention discloses a protecting device for unmanned aerial vehicle falling preventing. The protecting device comprises a device body; a fixing box is welded to the outer wall of the bottom of thedevice body, and a sliding ring sliding groove is formed in the outer wall of one side of the fixing box; a sliding ring is slidably connected to the inner wall of the sliding ring sliding groove, and a connecting rod is connected to the outer wall of the sliding ring through hinges; the outer wall of one end of the connecting rod and the outer wall of one side of the device body are connected with the same rotating rod through hinges, and the same wind resisting cloth is fixed to the outer wall of the top of the rotating rod and the outer wall of one side of the device body through screws; and a mounting groove is formed in the outer wall of the bottom of the device body, and a magnetic conductive column is welded to the inner wall of the mounting groove. Wind resistance borne by the device body during falling can be increased, the falling speed and acceleration of the device body are decreased advantageously, collision force generated when the device body falls and then makes contact with the ground is decreased advantageously, reverse impact force borne by the device body is decreased through the elastic buffering effect of two damping springs, and thus the protective effect onthe device body is improved advantageously.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a protective device for preventing falling of drones. Background technique [0002] UAVs are widely used in aerial photography, agriculture, express transportation, disaster rescue and other fields. If the UAV fails and the UAV falls, the parts on the UAV will be damaged by strong impact. If there is no anti-fall protection, it will cause to serious economic losses. [0003] After searching, the Chinese Patent Publication No. is CN207374688U, which discloses a UAV fall protection device, including a protective bar, wing clips, support plates, sponge pads, springs, fixing bolts, partitions, and elastic cloth. In this device, the UAV is protected by the buffering effect of the protective bar, the sponge pad and the spring, and the impact force on the UAV body is reduced when the UAV falls. Larger, directly falling to the ground will produce a huge impact force, the buffer effect o...

Problems solved by technology

In this device, the UAV is protected by the buffering effect of the protective bar, the sponge pad and the spring, and the impact force on the UAV body is reduced when the UAV falls. Larger, directly falling to the ground will produce a huge impact force, the buffer effect of the protective rod, sponge pad and spring is limited, and the protection effect on the fuselage is insufficient, and the protective rod is easily damaged by a strong impact, which reduces the use of the device life
