[0002] As we all know, multi-rotor aircraft is a kind of aircraft, and quad-rotor aircraft is more common, and is widely used in technical fields such as military affairs and civil aerial photography. The two groups of rotors have the same direction of rotation, the two groups of rotors are forward and reverse rotors, and the two groups of rotors rotate in opposite directions to offset the huge torque of the body and maintain the balance of the body. Attitude and position, due to the compact structure and flexible movement of this type of aircraft, it is generally suitable for relatively small spaces or complex terrain environments and positions. Larger, less portable, and more expensive to maintain

Embodiment Construction
[0021] As shown in the figure, a portable foldable quadrotor aircraft includes a body main frame 1, a cantilever 2 and a landing gear 3, and the main body frame 1, the cantilever 2 and the landing gear 3 are all made of ABS. The body main frame 1 comprises a top plate 4, a bottom plate 5 and four support columns 6, and the four support columns 6 are fixed between the top plate 4 and the bottom plate 5 at four corners of the top plate 4 and the bottom plate 5, and the support columns 6 Two first fixing holes 7 are oppositely arranged on the support column 6 of an n-shaped structure, and an equipment compartment is formed between the top plate and the bottom plate, which is used to load the flight control board, data link, power supply and power battery of the aircraft;
[0022] The number of the cantilever 2 is four, the cantilever 2 is an n-shaped structural profile, and the cantilever 2 is respectively provided with two second fixing holes 8, two third fixing holes 9 and two f...

The invention relates to a portable foldable four-rotor aircraft which comprises a main frame of an aircraft body, a cantilever and an undercarriage, wherein the cantilever is fixed on the main frame of the aircraft body in a rotating form through a first fixing shaft and the undercarriage is fixed on the cantilever in a rotating form through a third fixing shaft. The portable foldable four-rotor aircraft has the advantages of compact structure, small size, quick mounting and detaching, easiness in maintenance and low cost, and the assembling efficiency can be improved to the maximum extent.
Description
technical field [0001] The invention relates to a portable aircraft, in particular to a portable foldable quadrotor aircraft structure. Background technique [0002] As we all know, multi-rotor aircraft is a kind of aircraft, and quad-rotor aircraft is more common, and is widely used in technical fields such as military affairs and civil aerial photography. The two groups of rotors have the same direction of rotation, the two groups of rotors are forward and reverse rotors, and the two groups of rotors rotate in opposite directions to offset the huge torque of the body and maintain the balance of the body. Attitude and position, due to the compact structure and flexible movement of this type of aircraft, it is generally suitable for relatively small spaces or complex terrain environments and positions. Larger, not easy to carry, and higher maintenance costs. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention prop...
