[0002] A drone is an aircraft that does not require a pilot and is controlled remotely or autonomously. It combines advanced achievements from multiple fields such as aviation technology, electronic technology, and computer technology, and has wide applications in military, civilian, and scientific research fields.

[0003] Small training drones are a type of drone, mainly used for flight skills teaching, scientific research experiments, and industry simulation training. They allow operators to master basic drone flight operation skills through training. However, some small training drones have fixed wings, which means that the wings are always in the extended state. This results in the small training drone taking up a lot of space, making it inconvenient for operators to carry and transport it.

[0004] Therefore, this invention provides a portable foldable small training drone wing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a portable foldable small training drone wing device, which aims to solve the problem that in the prior art, the wings of some existing small training drones are fixed when in use, which causes the wings of the small training drone to always be in an unfolded state, resulting in the small training drone occupying a large space and making it inconvenient for operators to carry and transport the small training drone.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable foldable small training drone wing device, comprising a drone body, with mounting seats connected to the outer surfaces of the four corners of the drone body. A folding groove is formed on one side surface of the mounting seat, and one end of the wing body is connected to the inner surface of the folding groove. A rotating shaft is connected through the top surface of the mounting seat, with one end of the rotating shaft slidingly passing through a through hole in the top surface of the wing body and the other end of the rotating shaft extending into a slot. The slot is formed on the bottom surface inside the folding groove. A connecting plate is connected to the top surface of the rotating shaft, and the bottom surface of the connecting plate contacts the top surface of the mounting seat. A butterfly bolt is connected through the top surface of the mounting seat on one side of the connecting plate, with one end of the butterfly bolt passing through a limiting hole in the top surface of the wing body and the other end of the butterfly bolt forming a threaded connection with a first fixing hole. The butterfly bolt can also pass through the limiting hole and form a threaded connection with a second fixing hole.

[0007] As a preferred embodiment of the portable foldable small training drone wing device of this utility model, the wing body is slidably connected to the mounting base through a folding groove.

[0008] As a preferred embodiment of the portable foldable small training drone wing device of this utility model, the wing body is rotatably connected to the pivot through a through hole.

[0009] As a preferred embodiment of the portable foldable small training drone wing device of this utility model, the position and size of the through hole match the position and size of the slot, and the rotating shaft forms a sliding connection with the mounting base through the slot.

[0010] As a preferred embodiment of the portable foldable small training drone wing device of this utility model, the first fixing hole is opened on the bottom surface inside the folding groove, and the second fixing hole is opened on the top surface inside the folding groove. The position and size of the first fixing hole and the second fixing hole match the position and size of the limiting hole.

[0011] As a preferred embodiment of the portable foldable small training drone wing device of this utility model, the top surface of the connecting plate is symmetrically connected with bolts, and the other end of the bolts forms a threaded connection with the threaded holes, which are symmetrically opened on the top surface of the mounting base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes the cooperation of a mounting base, folding groove, pivot, butterfly bolt, limiting hole, first fixing hole, and second fixing hole. When the operator twists the butterfly bolt, allowing one end of the butterfly bolt to separate sequentially from the first fixing hole and the limiting hole, the wing body can slide in the folding groove through the pivot, allowing the wing body to fold onto the outside of the drone body. Then, the butterfly bolt is screwed through the limiting hole into the second fixing hole to fix the position of the folded wing body. In this way, the operator can reduce the space occupied by the drone body by folding and fixing the wing body, thus making it more convenient to carry and transport the drone body.

[0014] This invention utilizes the interplay of a connecting plate, bolts, and threaded holes. By tightening the bolts, one end of the bolt is disengaged from the threaded hole. Then, by pulling the connecting plate, the connecting plate, along with the rotating shaft, is disengaged from the slot and through hole in sequence. At this point, the rotating shaft no longer restricts one end of the wing body, allowing that end of the wing body to be disengaged from the folding groove. This enables the wing body to be detached independently from the mounting base, thus facilitating the maintenance of the wing body. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a portable foldable small training drone wing device, including a drone body 1, with mounting seats 2 connected to the outer surfaces of the four corners of the drone body 1. A folding groove 3 is opened on one side surface of the mounting seat 2, and one end of the wing body 4 is connected to the inner surface of the folding groove 3. A rotating shaft 5 is connected through the top surface of the mounting seat 2. One end of the rotating shaft 5 slides through a through hole 6 opened on the top surface of one end of the wing body 4, and the other end of the rotating shaft 5 extends into a slot 7. The slot 7 is opened on the bottom surface inside the folding groove 3. A connecting plate 12 is connected to the top surface of the rotating shaft 5. The bottom surface of the connecting plate 12 contacts the top surface of the mounting seat 2. A butterfly bolt 8 is connected through the top surface of the mounting seat 2 on one side of the connecting plate 12. One end of the butterfly bolt 8 passes through a limiting hole 9 opened through the top surface of one end of the wing body 4, and the other end of the butterfly bolt 8 is threadedly connected to a first fixing hole 10. The butterfly bolt 8 can also be threadedly connected to a second fixing hole 11 through the limiting hole 9.

[0023] It should be noted that the connecting wires in the drone body 1 can be connected to the internal components of the wing body 4 by opening matching through slots on the wing body 4, so that the internal components of the wing body 4 can be used normally, and the drone body 1 is a small drone.

[0024] Preferably, the wing body 4 is slidably connected to the mounting base 2 through the folding groove 3, and the wing body 4 is rotatably connected to the rotating shaft 5 through the through hole 6.

[0025] In practical use, when the wing body 4 rotates on the rotating shaft 5, the wing body 4 will also slide in the folding groove 3 on the mounting base 2, so that the wing body 4 can be unfolded or folded on the mounting base 2 through the folding groove 3.

[0026] Preferably, the position and size of the through hole 6 match the position and size of the slot 7, and the rotating shaft 5 forms a sliding connection with the mounting base 2 through the slot 7.

[0027] In practical use, when one end of the wing body 4 is slidably placed into the folding groove 3 on the mounting base 2, the position of the through hole 6 on the wing body 4 can be aligned with the position of the slot 7. At this time, one end of the rotating shaft 5 can slide through the through hole 6 and be inserted into the slot 7, so that the rotating shaft 5 can restrict one end of the wing body 4. By pulling the rotating shaft 5 upward, the rotating shaft 5 can be slid out of the slot 7 and the through hole 6, and the rotating shaft 5 can be separated.

[0028] Preferably, the first fixing hole 10 is formed on the bottom surface inside the folding groove 3, and the second fixing hole 11 is formed on the top surface inside the folding groove 3. The position and size of the first fixing hole 10 and the second fixing hole 11 match the position and size of the limiting hole 9.

[0029] In practical use, when the wing body 4 is unfolded in the folding groove 3 away from the drone body 1, the limiting hole 9 on the wing body 4 will move to the position of the first fixing hole 10. At this time, the butterfly bolt 8 is inserted through the limiting hole 9 and screwed into the first fixing hole 10 to fix the unfolded wing body 4. When the wing body 4 is folded in the folding groove 3 and closes to the drone body 1, the limiting hole 9 on the wing body 4 will move to the position of the second fixing hole 11. At this time, the butterfly bolt 8 is inserted through the limiting hole 9 and screwed into the second fixing hole 11 to fix the retracted wing body 4.

[0030] Preferably, bolts 13 are symmetrically connected through the top surface of the connecting plate 12, and the other end of the bolt 13 forms a threaded connection with the threaded hole 14. The threaded hole 14 is symmetrically opened on the top surface of the mounting base 2.

[0031] In practical use, when one end of the wing body 4 is slidably placed into the folding groove 3 on the mounting base 2, and one end of the rotating shaft 5 is inserted into the slot 7 through the through hole 6 on the wing body 4, the connecting plate 12 will come into contact with the mounting base 2. The bolt 13 is then screwed through the connecting plate 12 into the threaded hole 14 on the mounting base 2, which will fix the position of the connecting plate 12. At this time, the position of the rotating shaft 5 will also be fixed, so that the wing body 4 can rotate normally on the rotating shaft 5.

[0032] Working principle: When using this portable foldable small training drone wing device, the operator can operate the drone body 1 via a controller wirelessly connected to the drone body 1. The operator can drive the propeller on the wing body 4 to rotate, allowing the drone body 1 to take off or land, enabling the operator to practice drone control. When the operator needs to transport the drone body 1, the butterfly bolt 8 can be turned first, causing one end of the butterfly bolt 8 to separate from the first fixing hole 10 and the limiting hole 9. At this time, the butterfly bolt 8 no longer restricts the position of the wing body 4, allowing the wing body 4 to slide in the folding groove 3 via the pivot 5. The wing body 4 will then move towards the drone body 1, folding. When the wing body 4 can no longer slide in the folding groove 3, the second fixing hole 11 on the top inner side of the folding groove 3 will coincide with the limiting hole 9 on the wing body 4. Then, the butterfly bolt 8 is screwed through the limiting hole 9 into the second fixing hole 11, allowing the folded wing body 4 to... By fixing the position, the other wing bodies 4 can be folded sequentially, reducing the space occupied by the small training drone and making it easier to carry and transport. When the drone body 1 needs to be used again, the butterfly bolt 8 can be unscrewed, allowing the wing body 4 to slide again in the folding slot 3 via the pivot 5, enabling the wing body 4 to unfold. When the wing body 4 can no longer slide in the folding slot 3, the position of the first fixing hole 10 will move to the limiting hole 9. At this time, the butterfly bolt 8 is inserted through the limiting hole 9 and screwed into the first fixing hole 10. This can fix the unfolded wing body 4 in place, allowing the wing body 4 to be used normally. Secondly, when a wing body 4 is damaged, the bolt 13 can be loosened to allow one end of the bolt 13 to separate from the threaded hole 14. At this time, the connecting plate 12 can be pulled, allowing the connecting plate 12 and the rotating shaft 5 to separate from the slot 7 and the through hole 6 in sequence. At this time, the rotating shaft 5 no longer restricts one end of the wing body 4, allowing one end of the wing body 4 to separate from the folding groove 3, so that the wing body 4 can be removed from the mounting base 2, thus bringing convenience to the maintenance of the wing body 4.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
