Small portable unmanned aerial vehicle with wings capable of being contracted

Abstract

The invention discloses a small portable unmanned aerial vehicle with wings capable of being contracted. The small portable unmanned aerial vehicle comprises an unmanned aerial vehicle assembly and anunmanned aerial vehicle rotor wing assembly, wherein the unmanned aerial vehicle assembly comprises a plane body shell, four rotor wing connecting rods, undercarriages and a camera. The four rotor wing connecting rods are uniformly distributed on the outer side of the plane body shell and the rotor wing connecting rods and the plane body shell are formed integrally, and the undercarriages are located below the plane body shell. Contraction springs are arranged at the joints of blade connecting seats and rotor blades, the rotor blades can be contracted by the contraction springs when not in use to reduce the space occupied by the rotor blades, and the rotor blades can be protected to prevent the rotor blades from being damaged due to accidental impact; and the rotor blades are opened by centrifugal force when in use without affecting normal use, and blade protection frames are arranged below the rotor blades and are contracted together with the rotor blades, so that the size of the unmanned aerial vehicle is smaller.

Description

technical field [0001] The invention belongs to the technical field of drones, and in particular relates to a small portable drone with retractable wings. Background technique [0002] According to the application field, drones can be divided into military and civilian. For military use, drones are divided into reconnaissance aircraft and target drones. For civilian use, the application of drone industry is the real rigid demand of drones; , 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, and romantic applications, greatly expanding the use of the drone itself . [0003] Most of the original UAV rotors are fixed. When the UAV fuselage is small, the rotor will appear relatively large, which takes up more space when placed and is easy to break. It is also relatively large, which is inconvenient...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a small portable unmanned aerial vehicle with retractable wings, to solve the above-mentioned background technology, the original unmanned aerial vehicle rotors are mostly fixed. It will appear relatively large, take up a lot of space when placed, and is easy to break. At the same time, after the rotor protection frame is installed, it also takes up a relatively large space, which is inconvenient to hold and place.
