specific Embodiment approach
[0015] The preferred embodiment of the laterally folding quadrotor aircraft of the present invention is:
[0016] It includes a fuselage, the side of the fuselage is provided with a plurality of transverse folding arms, the lower part of the fuselage or the transverse folding arms is provided with a plurality of detachable landing gears, and the ends of the transverse folding arms are provided with Has detachable rotors.
[0017] The horizontal folding support arm includes an inner arm and an outer arm, one side of the inner arm and the outer arm are hinged to each other, the other side of the inner arm is provided with a pin shaft, and the other side of the outer arm is provided with an elastic When the inner arm and the outer arm are unfolded, the protrusion is stuck on the pin shaft, and when the inner arm and the outer arm are folded, the protrusion is separated from the pin shaft.
[0018] The lower part of the fuselage or the transverse folding arm is provided with a so...
specific Embodiment
[0020] Such as Figure 1 to Figure 5b As shown, it includes detachable landing gear 1, fuselage 2, detachable rotor 3, lateral folding arm 4 and other parts.
[0021] Such as figure 1 As shown, the detachable rotor 3 can be quickly folded and supported by the horizontal folding arm 4, and the specific folding method is as follows Figure 2a , 2b , as shown in 2c, its support and fixing methods are as follows Figure 3a , 3b shown. The dismounting and fixing mode of detachable undercarriage 1 are as follows: Figure 4a , 4b As shown, the partially enlarged schematic diagram of the detachable landing gear 1 is shown as Figure 5a , 5b shown.
[0022] Each component is described as follows:
[0023] (1) The four horizontal folding arms of the aircraft can be folded horizontally, and are in the folded state during storage and transportation, such as Figure 2c As shown, the transportation space can be reduced. When working, the arm can be opened, such as Figure 2a sh...

Abstract
The invention discloses a transverse folding type four-rotor aircraft. The transverse folding type four-rotor aircraft comprises an aircraft body, wherein a plurality of transverse folding support arms are arranged at the side parts of the aircraft body, a plurality of detachable undercarriages are arranged at the lower part of the aircraft body or the lower parts of the transverse folding support arms, and detachable rotors are arranged at the end parts of the transverse folding support arms. According to the transverse folding four-rotor aircraft, the problems that traditional four-rotor crosses and undercarriages in a fixed structure are large in occupied area and are inconvenient to store and transport are solved; the transverse folding type four-rotor aircraft is simple in structure, is efficient and is convenient to carry and operate.
Description
technical field [0001] The invention relates to a quadrotor aircraft, in particular to a laterally folding quadrotor aircraft. Background technique [0002] 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, and has the characteristics of stable flight, hovering, side flight and inverted flight. . No turning radius required, flexible. It is suitable for fixed-point reconnaissance, photography, aerial surveying and mapping and other tasks. [0003] The rotors and landing gear structures of the quadrotor aircraft in the prior art have been fixed, which makes the aircraft bring a larger volume during carrying and transportation. Although some quadrotors also adopt a folding structure, such as the MD4-1000 aircraft of Germany, although the folding structure is adopted, the folded volume is still very large, which brings inconve...
