Abstract

The invention discloses a multi-rotor wing aircraft. The multi-rotor wing aircraft comprises a power system and a distance change system. The power system comprises a main rotatable part, multiple driving parts and rotor wings connected respectively to the driving parts. The main rotatable part is provided with a rotatable end. The driving parts are driven by the rotatable end and transmit rotation to the rotor wings so that the rotor wings rotate synchronously. The distance change system comprises multiple distance change units. The distance change units are used respectively for changing incidence angles of the rotor wings. The driving parts are driven by the same rotatable end and the driving parts transmit rotation to the rotor wings so that the rotor wings rotate synchronously. Through distance change of the rotor wings, the multi-rotor wing aircraft can turn over, fly reversely or swing.

Description

technical field [0001] The invention relates to the field of electronic toys, in particular to a multi-rotor aircraft. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, the types of electronic toys are becoming more and more abundant, and the functions are becoming more and more powerful. Among these electronic toys, aircraft, as a high-end electronic toy, is deeply loved by the majority of aircraft model enthusiasts. These aircraft can be controlled wirelessly and remotely. According to their usage and performance, these aircraft can be divided into several categories such as toys, model airplanes, civil and military. Depending on the fuel used, these aircraft can be divided into gasoline-powered and electric-powered. The biggest advantage of gasoline is that it has a long battery life, and it can fly as long as it is refueled in time, and it has strong horsepower. However, the risk f...
