[0047] The principle of the present invention is:

[0048] When the present invention is in use, the tripod 3 is unfolded and then fixedly installed under the frame 1 through the fastener 33. After use, the tripod 3 can be disassembled, thereby facilitating the reduction of the size of the folded drone of the present invention. At the same time, the tripod 3 is also foldable. When the tripod 3 is not in use, it can be folded and placed in a backpack, which also helps to reduce the size of the folded drone of the present invention.

[0049] When the present invention is used, the arm 5 needs to be unfolded, and the drone of the present invention can be folded as shown in the attached figure. Fig.13 As shown, the first arm 51 is as shown Figure 1As shown on the outside, it is folded counterclockwise at the innermost side, the second arm 52 is folded clockwise in the middle, and the third arm 53 is folded counterclockwise at the outermost side. At this time, the second clamp 82 in the second locking mechanism 8 is pressed down or lifted, so the clamp head 821 will be lifted. When the clamp head 821 is separated from the clamp head matching part 91, the arms can be unfolded in sequence. At this time, the battery 4 can be installed for use. After use, the battery 4 is removed and the arm 5 and the propeller 6 are folded. It should be noted that in the present invention, the structural design of the second locking mechanism 8 at each position is slightly different. It is adapted to the outer shell 2 and is convenient for use in actual operation. Although there are some differences in structure, the principle is the same. It is not difficult for technicians in the field of this invention to understand, so it will not be explained separately.

[0050] During the use of the drone of the present invention, different types of parachutes can be adapted, such as cylindrical and rectangular types, but only one type can be configured at a time. The parachute matching part 23 on the shell 2 is ABS plastic. When the parachute is equipped, this part is adaptively cut according to the type of the parachute to facilitate the ejection of the parachute.

[0051] In an application example of the present invention, the empty weight is 23kg, the wheelbase is 2200mm; the layout is 6-axis and 6-propeller, the standard load is 50kg; the empty-load endurance is 70min, and the 50kg endurance is 25min; it can withstand wind level 6, the operating temperature is -20 to 60℃; the maximum flight speed is 20m / s, and the maximum operating altitude is 5000m.

[0052] In this example, the drone of the present invention is 1140 mm long, 860 mm wide and 350 mm high after being folded, and has an extremely small storage size. At the same time, the tripod 3 is 820 mm long, 630 mm wide and 115 mm high after being folded, and the tripod 3 is 430 mm high before being folded, which effectively reduces the size of the tripod 3 and also facilitates storage, bringing convenience to use.

[0053] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
