[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A drone with a foldable cantilever comprises a drone body 1, an adjustable cantilever 11 is arranged on the surface of the drone body 1, a propeller 12 is fixedly mounted on the surface of the adjustable cantilever 11, a landing gear 13 is fixedly connected to the lower surface of the drone body 1, a folding mechanism is arranged on the surface of the drone body 1, the folding mechanism comprises a rotating seat 2, the rotating seat 2 is fixedly connected to the surface of the drone body 1, a rotating rod 21 is rotatably connected to the surface of the rotating seat 2, the rotating rod 21 is fixedly connected to the surface of the adjustable cantilever 11, a worm gear 22 is fixedly connected to the bottom of the rotating rod 21, a fixing block 23 is fixedly connected to the bottom of the drone body 1, a motor 24 is fixedly connected to the surface of the fixing block 23, a bidirectional worm 25 is fixedly connected to the output shaft of the motor 24, a transmission wheel 26 is fixedly connected to the surface of the bidirectional worm 25, and a transmission belt 27 is transmission-connected to the surface of the transmission wheel 26, and the folding mechanism adopts one motor 24, so that four groups of adjustable cantilevers 11 can be folded simultaneously, and manual folding is not required, thereby improving the folding efficiency and reducing the risk of personnel operating the folding.

[0024] Furthermore, the adjustable cantilever 11 includes a rotating arm 3, an adjusting arm 31 is slidably connected to the surface of the rotating arm 3, all positioning holes 32 are opened on the surface of the adjusting arm 31, a fixing nut 33 is fixedly connected to the surface of the rotating arm 3, and a limiting bolt 34 is threadedly connected to the surface of the fixing nut 33. The adjustable cantilever 11 can be adjusted in length and can be adjusted accordingly according to different needs and environments, thereby improving the adaptability and flexibility of the drone body 1. When long-distance flight is required, the adjustable cantilever 11 can be lengthened; when rapid maneuvering is required, the adjustable cantilever 11 can be shortened.

[0025] Furthermore, the adjustable cantilever 11 rotates on the rotating seat 2 through the rotating rod 21, and the rotating rod 21 drives the worm gear 22 and the adjustable cantilever 11 to rotate synchronously. Two groups of bidirectional worm gears 25 are provided, and each group of bidirectional worm gears 25 is meshed with two groups of worm gears 22 at the same time. The bidirectional worm gear 25 has spiral grooves in two directions and can realize bidirectional transmission. When the bidirectional worm gear 25 rotates, it can drive the two groups of worm gears 22 to rotate in opposite directions at the same time.

[0026] Furthermore, the motor 24 drives the bidirectional worm 25 to rotate through the output shaft, and the bidirectional worm 25 drives the worm wheel 22 to rotate, and the rotation directions of the two sets of worm wheels 22 are opposite. The worm wheel 22 causes the adjustable cantilever 11 to rotate and fold on the rotating seat 2 through the rotating rod 21, so that the folding process of the adjustable cantilever 11 does not require manual operation, avoiding the risk of manual folding of the adjustable cantilever 11.

[0027] Furthermore, two groups of transmission wheels 26 are provided, and the transmission belt 27 is simultaneously connected to the two groups of transmission wheels 26, and the transmission wheels 26 rotate synchronously on the fixed block 23 through the transmission belt 27. At this time, the two groups of bidirectional worm gears 25 rotate synchronously on the fixed block 23 through the transmission wheels 26 and the transmission belt 27, and the two groups of fixed blocks 23 drive the four groups of worm gears 22 to rotate, thereby making the four groups of adjustable cantilevers 11 folded at the same time, thereby improving the folding efficiency of the adjustable cantilever 11.

[0028] Furthermore, a guide groove is opened on the surface of the rotating arm 3, and the adjusting arm 31 slides on the guide groove of the rotating arm 3. The adjusting arm 31 changes the length of the adjustable cantilever 11 by sliding on the rotating arm 3. There are multiple groups of positioning holes 32, which are linearly and evenly arranged on the surface of the adjusting arm 31. The diameter of the positioning holes 32 is the same as the diameter of the limit bolt 34.

[0029] Furthermore, a circular hole is opened on the surface of the rotating arm 3, and the limiting bolt 34 passes through the positioning hole 32 and the circular hole of the rotating arm 3 at the same time. The guide groove of the rotating arm 3 is connected to the circular hole of the rotating arm 3. The limiting bolt 34 passes through the positioning hole 32 on the guide groove of the rotating arm 3. The limiting bolt 34 limits the position of the adjusting arm 31 on the rotating arm 3, and the limiting bolt 34 is fixedly connected to the rotating arm 3 through the fixing nut 33.

[0030] Working principle: the output shaft of the motor 24 drives the bidirectional worm 25 to rotate, and the bidirectional worm 25 drives the transmission wheel 26 to rotate during the rotation. The transmission wheel 26 drives another set of transmission wheels 26 to rotate through the transmission belt 27, and then the transmission wheel 26 drives another set of bidirectional worm 25 to rotate. The two sets of bidirectional worm 25 rotate synchronously at this time. The two sets of bidirectional worm 25 drive the four sets of worm wheels 22 to rotate, and the two sets of worm wheels 22 rotate clockwise, and the two sets of worm wheels 22 rotate counterclockwise. The worm wheel 22 drives the adjustable cantilever 11 to rotate on the rotating arm 3 through the rotating rod 21, so that the four sets of adjustable cantilevers 11 are folded on the drone body 1.

[0031] The adjusting arm 31 is slid on the guide groove of the rotating arm 3 to adjust the length of the adjustable cantilever 11. At this time, the limiting bolt 34 passes through the circular hole of the rotating arm 3, so that the limiting bolt 34 passes through the positioning hole 32, and the limiting bolt 34 is threadedly connected to the fixing nut 33. The limiting bolt 34 is fixed to the rotating arm 3 through the fixing nut 33, and the limiting bolt 34 limits the position of the adjusting arm 31 through the positioning hole 32, thereby completing the adjustment of the length of the adjustable cantilever 11.
