A foldable UAV with a propeller protection mechanism

Abstract

The invention discloses a foldable unmanned aerial vehicle equipped with a propeller protection mechanism, comprising an unmanned aerial vehicle body and a driving rotor, a movable arm and a folding rod are arranged between the driving rotor and the unmanned aerial vehicle body, and the movable arm A reinforced sliding rod is arranged between the movable arm and the folding rod, and the reinforced sliding rod forms a sliding structure inside the movable arm and the folding rod. The driving rotor is installed on the outer end of the folding rod, and the outer side of the driving rotor is provided with a thickened protective airbag. The inside of the folding rod is provided with a compressed air bag, and the side end of the reinforced sliding rod forms a sticking extrusion structure to the side end of the compressed air bag. The invention provides a movable arm and a folding rod folding mechanism, and a built-in reinforced sliding rod that reinforces the folding part. The reinforced sliding rod cooperates with the equipment to unfold and fold as a whole, and the reinforced sliding rod can play the role of a piston and push the compressed air bag to drive the thickened protective air bag to inflate. The protective drive rotor is easy to fold and has good structural protection and safety.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a foldable unmanned aerial vehicle with a propeller protection mechanism. Background technique [0002] UAV is an aircraft controlled by radio remote control equipment and corresponding program. Since there is no need to consider manned space and other issues, the structure is quite different from that of ordinary aircraft, especially some small UAVs, many of which are equipped with multi-rotors. Drive structure, each rotor and corresponding drive motor equipment are installed and supported by externally extending support arms, and the purpose of stable flight driving is achieved through the cooperation of multiple small rotors; [0003] However, there are still some problems when the existing rotor structure UAV is used: [0004] 1. The supporting arm structure used for installing the rotor is mostly an integrated structure with fixed support. Although the over...
