A portable and collapsible spherical drone

Abstract

The invention discloses a portable foldable spherical drone. Aiming at the problems that the traditional multi-rotor UAV cannot be folded and takes up a lot of space, this UAV proposes a portable and collapsible spherical UAV solution. The UAV is divided into two states, namely the folded state and the unfolded state, and the two states can be converted to each other. Compared with the prior art, the technical solution adopted by the present invention has the following technical effects: the unique foldable spherical design makes the drone introduce some artistic elements, and the drone has a certain artistic appreciation; the compact self-locking The structural design ensures that the position of the arm and the fuselage of the UAV is relatively fixed when flying, and the UAV does not add additional mass; the unique folding structure and spherical structure design greatly improve the portability of the UAV. It is easy for users to carry it when going out and individual soldiers; when it is unfolded, the UAV is in quadrotor mode, with stable flight and simple operation.

Description

technical field [0001] The invention relates to the technical field of aviation systems, in particular to a portable and foldable spherical unmanned aerial vehicle. Background technique [0002] UAVs are widely used in aerial surveying and mapping, film and television shooting, enemy situation survey, disaster detection, power inspection and other fields, and are the best in the aircraft family. In particular, the multi-rotor UAV is a vertical take-off and landing aircraft with novel structure and superior performance. It has the characteristics of simple operation and strong load carrying capacity, and has extremely important military and civilian values. [0003] However, when the traditional multi-rotor drone is parked, the rotor is directly exposed, the cantilever is long, it cannot be folded, and it takes up a lot of space. It needs a special storage box, which is not easy to carry; The rotor of the UAV is easily damaged when an accident occurs, and sometimes the rotor...

AI Technical Summary

Problems solved by technology

[0003] However, when the traditional multi-rotor drone is parked, the rotor is directly exposed, the cantilever is long, it cannot be folded, and it takes up a lot of space. It needs a special storage box, which is not easy to carry; When an accident occurs to a UAV, the rotor is easily damaged, and sometimes the high-speed rotating rotor can cause personal injury to personnel

In view of the above problems of being non-foldable and taking up a large space, although the existing multi-rotor UAVs also have foldable design elements, in the folded state, the space occupied by the quad-rotor UAV is still large, and the folding mechanism is relatively complicated. prone to mechanical failure

Aiming at the problem that the high-speed rotating rotors of UAVs are directly exposed to the outside, the existing quadrotor UAVs are equipped with propeller covers on each rotor, but the detachability of the propeller covers is poor, and the UAV is added. number of parts

Although some multi-rotor UAVs are equipped with integrated non-detachable paddle covers, this greatly reduces the folding performance of the UAV.
