Unmanned aerial vehicle shell with omnidirectional anti-collision structure

Abstract

The invention discloses an unmanned aerial vehicle shell with an omnidirectional anti-collision structure. The unmanned aerial vehicle shell with the omnidirectional anti-collision structure comprises an unmanned aerial vehicle. Screw propellers are arranged on four corners of the top part of the unmanned aerial vehicle; a circular groove is concavely arranged in the center of a shell on the top part of the unmanned aerial vehicle; a guide pillar is vertically connected into the circular groove; the bottom end of the guide pillar is in threaded connection with the shell of the unmanned aerial vehicle; an annular rubber sheet is embedded into the circular groove in a way of surrounding the bottom end of the guide pillar; a top plate is fixedly connected to the top end of the guide pillar; a spring is arranged on the guide pillar in a sleeving way; protective screen plates are hinged to two sides of the top plate and cover the screw propellers; semi-circular rings are welded to the lower side faces of the protective screen plates; a movable pipe sleeve is arranged on a position, located under the spring, of the guide pillar in a sleeving way; and lifting blocks are symmetrically arranged on the outer side wall of the lower part of the movable pipe sleeve. According to the unmanned aerial vehicle shell with the omnidirectional anti-collision structure provided by the invention, partial structures of a shell and a support of an existing unmanned aerial vehicle are improved, the protective screen plates are additionally arranged, a support frame of the unmanned aerial vehicle is improved, and a protective frame is arranged, so that the protection on the unmanned aerial vehicle is realized, and the stability of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of UAV safety protection, in particular to an UAV casing with an all-round anti-collision structure. Background technique [0002] Unmanned aircraft, referred to as "drone" for short, and "UAV" for English abbreviation, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned parawing aircraft, etc. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, selfies,...

AI Technical Summary

Problems solved by technology

[0003] When the UAV is used and parked, it is vulnerable to external impact. When the impact force is too large, it is easy to cause damage to the UAV.

Especially when flying, the propeller of the UAV is damaged by impact, which may easily cause the UAV to lose balance or fall, while the existing UAV impact protection device is either lacking, or it is pressed down with the impact force, and there is no buffer, which hinders the propeller. rotation

However, the UAV on the ground is under the impact force of the downward pressure, lacks cushioning and reinforcement, and the UAV is easy to overturn, causing the propeller to collide with the ground and be damaged.

For drones flying in areas where high and low objects are distributed, the camera device is easily hit by protruding objects below, resulting in damage to the camera device and affecting shooting
