[0017] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Figure 1 and Figure 2 The cyclone quadcopter shown includes a drone body 1, four lateral connecting arms 2 are fixed on the outer side of the drone body 1, and a flip-folding arm 3 with a motor and a blade installed at the end is movably installed on the outer side of the lateral connecting arm 2. The connecting end of the flip-folding arm 3 and the lateral connecting arm 2 is threadedly connected with an arm folding plastic connecting piece 4, and a tripod connecting tube 5 is fixedly installed on the flip-folding arm 3, and a drone tripod 6 is inserted inside the tripod connecting tube 5. The tripod connecting tube 5 and the drone tripod 6 are fixedly assembled by a tripod locating pin 7.

[0020] In order to improve the stability of the fuselage, the lateral connecting arms 2 are evenly arranged in a circular array on the outside of the drone fuselage 1.

[0021] In order to cooperate with the movable assembly, a lateral connecting frame 8 is fixed on the outer end of the lateral connecting arm 2, and the flip folding arm 3 is inserted into the lateral connecting frame 8 through the assembly block 9 at the connecting end and is movably connected to the assembly axis in the lateral connecting frame 8.

[0022] In order to improve the turning limiting capability, side assembly grooves 10 are symmetrically provided on both side walls of the assembly block 9 .

[0023] For the purpose of positioning, the end of the assembly block 9 has an integral positioning protrusion 11 , and the side wall of the lateral connection frame 8 is provided with a positioning groove 12 matching the positioning protrusion 11 .

[0024] A bottom receiving notch 13 is provided at the lower end of the drone body 1 for conveniently inserting the drone tripod 6 .

[0025] The present invention is composed of a drone body and circuit components. The drone body includes a drone body 1, a flip-folding arm 3, a motor, a rotor blade, a drone tripod 6, a folding arm plastic connector 4 and a tripod connecting pipe 5. The circuit components include a flight control system, an electronic speed controller ESC, a battery, and a remote control signal receiver. The electrical components are integrated and fixed to the inner bottom plate of the drone body 1.

[0026] Connection method: As shown in the figure, the flip folding arm 3 is connected to the drone body 1 through the lateral connecting arm 2, the flip folding arm 3 can rotate counterclockwise with the lateral connecting frame 8, and the flip folding arm 3 and the lateral connecting frame 8 can be fixed through the arm folding plastic connector 4.

[0027] The disassembly and fixation of the UAV tripod 6 and the tripod connecting pipe 5 are achieved through the tripod positioning pin 7.

[0028] Specific implementation of the aircraft folding structure: As shown in the figure, when the aircraft's flip folding arm 3 is unfolded, loosen the arm folding plastic connector 4 with internal threads clockwise, and slide the arm folding plastic connector 4 outward along the flip folding arm 3. At this time, the lateral connection frame 8 and the assembly block 9 are changed from the original fixed state to a rotatable movable part, and this part is respectively connected to the flip folding arm 3 and the lateral connection arm 2, so it can drive the flip folding arm 3 to rotate. Rotate the flip folding arm 3 counterclockwise until it rotates as shown in the figure. Figure 2 Then rotate the wing until it is parallel to the flip folding arm 3. The tripod positioning pin 7 acts as a spring fixing pin to fix the drone tripod 6 to the tripod connecting tube 5 connected to the drone fuselage 1. So press the tripod positioning pin 7 by hand, and the tripod positioning pin 7 will be separated from the fixed circular groove on the tripod connecting tube 5 due to the contraction of the spring force, and the tripod can be pulled out, as shown in FIG. Figure 2 As shown, the aircraft is folded most efficiently at this time. This cyclone folding technology has high folding efficiency and takes up little space when stored.
