Problems solved by technology

The rotor and landing gear structures of the quadrotor aircraft in the prior art have been fixed, resulting in a larger volume of the aircraft, which is not conducive to carrying and transportation
In the process of transportation, there are collisions, resulting in damage to the aircraft, causing the aircraft to be unable to fly or flying unbalanced; the large volume of the aircraft leads to high transportation costs, and it is inconvenient for users to carry

Abstract

The invention discloses a four-rotor craft which comprises a craft body; rotor wing racks are arranged on the left and right sides of the craft body; each rotor wing rack is connected with the craft body through a hinge mechanism which is used for folding the rotor wing rack by rotating the rotor wing rack around the craft body; a locking mechanism used for locking the corresponding rotor wing rack in an unfolded state is arranged between each rotor wing rack and the craft body. As the folding function is realized due to the hinge mechanisms, the function of folding the rotor wing racks in the unfolded state is realized due to the locking mechanisms, and the operation processes of folding and unfolding are convenient, the occupied area of the four-rotor craft is reduced, the aircraft is prevented from being damaged by collision, the carrying and the transportation are convenient, the structure is simple, and the performance is stable.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a quadrotor aircraft. Background technique [0002] With the continuous development of technology, aircraft are becoming more and more popular. The quadrotor aircraft is a kind of aircraft. The quadrotor aircraft realizes various actions by changing the speed of the rotor. Compared with other unmanned aerial vehicles, the quadrotor unmanned aerial vehicle is driven by four sets of motors. features such as stop, sideways flight and inverted flight. No turning radius required, flexible. It is suitable for fixed-point reconnaissance, photography, aerial surveying and mapping and other tasks. The rotors and landing gear structures of the quadrotor aircraft in the prior art have been fixed, resulting in a large volume of the aircraft, which is not conducive to carrying and transportation. In the process of transportation, collisions occur, causing damage to the aircraft, causing ...
