Portable unmanned aerial vehicle with anti-drop function

Abstract

The invention relates to a portable unmanned aerial vehicle with an anti-drop function. The portable unmanned aerial vehicle comprises a main body, four flying mechanisms, a retracting mechanism and four protection mechanisms. The retracting mechanism comprises a driving component and four retracting components. Each retracting component comprises a cover plate, a connecting line, a connecting rod, two sliding sleeves, two first springs and two sliding rods. Each protection mechanism comprises a storage box, a gas delivery pipe, a landing gear, an air bag and a trigger component. Each triggercomponent comprises a storage tank, a slider, a permanent magnet, an electromagnet, a second spring, a feed port and a limit ring. The portable unmanned flight device with the anti-drop function has the advantages that a propeller is retractable through the retracting mechanism, the unmanned aerial vehicle is downsized, and accordingly, the portability of the unmanned aerial vehicle is improved; through the protection mechanisms, the air bags are inflated when the unmanned aerial vehicle fails, and accordingly, the anti-drop performance of the unmanned aerial vehicle is improved under the buffer action of the air bags.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a portable unmanned flying device with an anti-drop function. Background technique [0002] Unmanned aircraft are unmanned aircraft operated by radio-controlled equipment and self-contained program controls, or operated completely or intermittently autonomously by on-board computers, and are often more suitable than manned aircraft for those Dirty or dangerous tasks, UAVs can be divided into military and civilian use according to the application field. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. Just needed, currently in aerial photography, agriculture, plant protection, micro selfie, express transportation, disaster relief, observing wild animals, monitoring infectious diseases, surveying and mapping, news reports, power inspections, disaster relief, film and television shooting, creating romance, etc. The use of UAV itsel...

Problems solved by technology

[0003] Nowadays, with the development of drone technology, drones have brought great convenience to users' lives. The drones in the prior art take up a lot of space, making it difficult to store, thus reducing the cost of carrying drones. Not only that, when the UAV is in flight, if it breaks down, the UAV needs to make a forced landing. When the UAV is in contact with the ground, it will generate a large impact force, resulting in no Damage to the man and machine reduces the usefulness of the drone
