Foldable unmanned aerial vehicle with propeller protection mechanism

Abstract

The foldable unmanned aerial vehicle with the propeller protection mechanisms comprises an unmanned aerial vehicle body and driving rotors, movable arms and folding rods are arranged between the driving rotors and the unmanned aerial vehicle body, and reinforcing sliding rods are arranged between the movable arms and the folding rods in a penetrating mode; and the reinforcing sliding rods form a sliding structure in the movable arms and the folding rods, the driving rotors are installed at the outer ends of the folding rods, thickened protective air bags are arranged on the outer sides of the driving rotors, compressed air bags are arranged in the folding rods, and the reinforcing sliding rods form an attaching and extruding structure for the side ends of the compressed air bags. A reinforcing sliding rod for reinforcing a folding part is arranged while a movable arm and a folding rod folding mechanism are provided, the reinforcing sliding rod is matched with equipment to be integrally unfolded and folded, the reinforcing sliding rod can play a role of a piston to push and extrude a compressed air bag in a linkage mode to drive a thickened protective air bag to inflate and protect a driving rotor, folding is convenient, and meanwhile the folding efficiency is improved. And the structure protection safety is good.

Description

technical field [0001] The invention relates to the technical field related to unmanned aerial vehicles, in particular to a foldable unmanned aerial vehicle equipped with a propeller protection mechanism. Background technique [0002] UAV is an aircraft controlled by radio remote control equipment and corresponding programs. Since there is no need to consider issues such as manned space, the structure is quite different from ordinary aircraft. Especially for some small UAVs, many of them use multi-rotor cooperation. The drive structure, each rotor and the corresponding drive motor equipment are installed and supported by the externally extended support arm, and the purpose of stable flight drive is achieved through the cooperation of multiple small rotors; [0003] However, when the existing rotor structure UAV is in use, there are still certain problems: [0004] 1. The support arm structure used to install the rotor is mostly an integrated structure with fixed support. Al...
