For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0027] like Figure 1 、 Figure 2 As shown, a foldable wing drone comprises: a body 1 and blades 5, the body 1 is provided with a folding wing group distributed around the body 1, and the blades 5 are installed at the ends of the folding wing group; the folding wing group comprises a first folding wing 2, a second folding wing 3 and a third folding wing 4 which are hinged in sequence; the first folding wing 2 is rotatably connected to the body 1, the blades 5 are installed at the ends of the third folding wing 4, and an origami wing 6 is provided between one side of the third folding wing 4 and the body 1, and the origami wing 6 is linked with the third folding wing 4 to be able to fly with the body 1. The origami wings 6 automatically unfold when unfolded and synchronously close when closed. The origami wings 6 comprise a cross-shaped first folding wing frame 601, a second folding wing frame 602, a third folding wing frame 603, a fourth folding wing frame 604, and a fifth folding wing frame 605. The first folding wing frame 601 is connected to the second folding wing 3, and the fifth folding wing frame 605 is connected to the body 1. The tops of the first folding wing frame 601, the second folding wing frame 602, the third folding wing frame 603, the fourth folding wing frame 604, and the fifth folding wing frame 605 are covered with a wing membrane. The wing membrane is made of one of silicone film, 210 polyester cloth, kite cloth material, composite film, and polyimide film.

[0028] like Figure 3 and Figure 4As shown, a fixing column 7 is provided at the bottom of the body 1, and a first collar 8 and a support leg 11 are sleeved on the fixing column 7. A spring 10 is fixed to the top of the support leg 11, and the top of the spring 10 abuts against the bottom of the first collar 8. A first bracket 9 is hinged to the first collar 8, and the end of the first bracket 9 is hinged to a second bracket 13 hinged to the first folding wing 2. An anti-trip buckle 12 is provided at the bottom of the fixing column 7. During the process of unfolding the folding wing group, when the first bracket 9 and the second bracket 13 pull the first collar 8 to move, a certain gap will be formed between the first collar 8 and the spring 10. The size of the gap determines the range of motion of the support leg 11.

[0029] like Figure 5 and Figure 6 As shown, the first folding wing frame 601 has the same structure as the fifth folding wing frame 605, and the second folding wing frame 602, the third folding wing frame 603 and the fourth folding wing frame 604 have the same structure. The first folding wing frame 601 and the fifth folding wing frame 605 are respectively provided with the first bearing 6011 with the highest and the lowest height, and the second folding wing frame 602, the third folding wing frame 603 and the fourth folding wing frame 604 are provided with second bearings 6021 with heights decreasing from the second folding wing frame 602 to the fourth folding wing frame 604. The first bearing 6011 and the second bearing 6021 are arranged in sequence from high to low, and a rotating shaft 14 is hinged between the first bearing 6011 and the second bearing 6021 and between each two adjacent second bearings 6021.

[0030] When the drone is in use, the first folding wing 2, the second folding wing 3, and the third folding wing 4 are folded sequentially through the hinge points. Simultaneously, the origami wings 6 are also closed synchronously with the folding of the third folding wing 4. This allows the drone to be significantly reduced in size when not in flight, making it easier to carry and store. This greatly improves the drone's portability and storage convenience, allowing users to easily put the drone into a backpack or suitcase for easy transportation to various usage scenarios.

[0031] When the drone needs to be deployed, the first folding wing 2 begins to unfold, either manually or through an electric drive mechanism. This in turn causes the second and third folding wings 3 and 4 to unfold. Simultaneously, the origami wings 6 automatically unfold as the third folding wings 4 unfold, forming a complete wing surface. This not only improves the drone's deployment efficiency but also ensures the integrity and stability of the wing surface, providing reliable support for the drone's flight.

[0032] When the drone is folded, support legs 11 are compressed by springs 10 and secured to fixed posts 7. There is minimal or no gap between first collar 8 and springs 10. This allows the drone to remain compact and stable in its folded state, avoiding the increased bulk and portability issues caused by dangling or extending support legs 11. The compression of springs 10 also provides the necessary power for the drone to unfold. Furthermore, springs 10 provide a certain cushioning effect for support legs 11 during landing, ensuring a stable landing.

[0033] When the drone unfolds the folding wing assembly, the first bracket 9 and the second bracket 13 pull the first ring 8 upward under the action of the driving mechanism. As the first ring 8 moves, a certain gap is formed between it and the spring 10. The size of this gap determines the range of motion of the support leg 11.

[0034] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
