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.

Abstract

The invention discloses a portable foldable spherical unmanned aerial vehicle. The scheme of the portable foldable spherical unmanned aerial vehicle is provided in order to solve the problems that a traditional multi-rotor unmanned aerial vehicle cannot be folded and is large in occupied space and the like. The unmanned aerial vehicle has two states which are the folded state and the unfolded state, and the two states can be switched. By the adoption of the technical scheme, compared with the prior art, the portable foldable spherical unmanned aerial vehicle has the following technical beneficial effects that due to the unique foldable spherical design, certain art elements are introduced into the unmanned aerial vehicle, and the unmanned aerial vehicle has certain artistic ornamental value; exquisite self-locking structural design guarantees that the unmanned aerial vehicle is not heavier on the basis that the positions of vehicle arms and a vehicle body are relatively fixed when the unmanned aerial vehicle flies; the unique folding structural design and spherical structural design are adopted, so that the portability of the unmanned aerial vehicle is greatly improved, and the unmanned aerial vehicle can be conveniently carried by a user outside and carried by a solider; and when in the unfolded state, the unmanned aerial vehicle is in a four-rotor mode, flight is stable, and operation is easy.

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...
