[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an easy-to-disassemble wing connection structure for aerial photography drones. This solves the technical problems of the current method of disassembling and assembling rotors by rotating screws, which requires multiple screw rotations during rotor assembly and disassembly, resulting in low rotor assembly and disassembly efficiency. Furthermore, the screws are prone to falling off and being lost during assembly and disassembly, affecting rotor assembly and disassembly.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a detachable wing connection structure for aerial photography drones is designed, including a lower cover plate and an upper cover plate. Mounting plates are connected to the four corners between the lower cover plate and the upper cover plate. Wings are provided at the four corners between the upper cover plate and the lower cover plate. Each of the four wings is provided with a propeller blade. The wings are hollow and circular. Slots are provided on both sides of the inner cavity of the wings. Support legs are installed at the bottom of the lower cover plate.

[0006] The mounting plate has a hollow structure. One end of the mounting plate near the wing is connected to a connecting cylinder. Both ends of the mounting plate are slidably penetrated by extrusion plates. The inner cavity of the connecting cylinder has a limiting groove. Two limiting blocks are slidably connected in the limiting groove. A movable plate is installed on each of the two limiting blocks. The two movable plates are connected to the two extrusion plates by movable rods. The ends of the two movable plates near the inside of the connecting cylinder are fixedly connected to insert rods. The insert rods slidably penetrate the connecting cylinder and are placed on the outside of the connecting cylinder. A first spring is sleeved on the outside of the insert rod inside the connecting cylinder. The two ends of the first spring are connected to the movable plate and the inner wall of the connecting cylinder, respectively.

[0007] Preferably, the inner cavity of the mounting plate is provided with a movable groove on both sides, and two movable blocks are slidably connected in each of the two movable grooves. Limiting rods are connected between the four movable blocks and the two ends of the two movable plates.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: A detachable wing connection structure for an aerial photography drone, see [link / reference] Figures 1 to 4The system includes a lower cover plate 1 and an upper cover plate 11. Mounting plates 2 are connected to the four corners between the lower cover plates 1 and 1. Wings 31 are installed at the four corners between the upper cover plate 11 and the lower cover plate 1. Each of the four wings 31 has a propeller blade 32. The wings 31 are hollow and circular, with slots 34 on both sides of their inner cavities. Support legs 12 are installed at the bottom of the lower cover plate 1. The mounting plates 2 are hollow, with a connecting cylinder 21 connected to one end of the mounting plate 2 near the wing 31. Both ends of the mounting plate 2 slide through. There is an extrusion plate 24, and a limiting groove 212 is opened in the inner cavity of the connecting cylinder 21. Two limiting blocks 213 are slidably connected in the limiting groove 212. A movable plate 210 is installed on each of the two limiting blocks 213. A movable rod 214 is connected between each of the two movable plates 210 and the two extrusion plates 24. An insertion rod 23 is fixedly connected to one end of each movable plate 210 near the inside of the connecting cylinder 21. The external dimensions of the insertion rod 23 are adapted to the internal dimensions of the slot 34, and the insertion rod 23 slides through the connecting cylinder 21 and is placed in the connecting... On the outside of the connecting cylinder 21, a first spring 211 is sleeved on the outside of the insert rod 23 inside the connecting cylinder 21. The two ends of the first spring 211 are respectively connected to the moving plate 210 and the inner wall of the connecting cylinder 21. During operation, by pushing the pressing plate 24 towards each other, the limiting block 213 moves within the limiting groove 212, thereby cooperating with the moving rod 214 to push the two moving plates 210 towards each other and house them inside the connecting cylinder 21. Then, the wing 31 is aligned with the connecting cylinder 21 and sleeved on the outside of the connecting cylinder 21, and the slot 3 is... 4. Corresponding to the insertion rod 23, the pressing plate 24 is released, and the moving plate 210 is moved by the elastic force of the first spring 211 to insert the insertion rod 23 into the slot 34, thus completing the fixation of the wing 31. When it is necessary to disassemble the wing 31, the insertion rod 23 is disengaged from the slot 34 by pushing the pressing plate 24 in opposite directions, and then the wing 31 is pulled outward, thereby quickly completing the disassembly of the wing 31, thereby improving the efficiency of the disassembly and assembly of the wing 31, and the disassembly and assembly of the wing 31 will not cause the loss of connecting components, which will affect the disassembly and assembly of the wing 31.

[0023] For details, see Figure 3 The inner cavity of the mounting plate 2 has movable grooves 26 on both sides. Two movable blocks 27 are slidably connected in each of the two movable grooves 26. Limiting rods 28 are connected between the four movable blocks 27 and the two ends of the two movable plates 210. Second springs 29 are installed on both sides of the inner cavity of the two movable grooves 26. The other ends of the four second springs 29 are respectively connected to the four movable blocks 27. The movable blocks 27 guide the movement in the movable grooves 26 and limit the movement of the movable plates 210 in conjunction with the limiting rods 28, thereby improving the stability of the movement of the movable plates 210. At the same time, the compression of the second springs 29 can assist the movable plates 210 to reset. When the first spring 211 is damaged, it does not affect the disassembly and assembly of the movable plates.

[0024] Further, see Figure 4The inner cavity of the wing 31 is equipped with a fixing plate 35, and a third spring 36 is installed on the fixing plate 35. When the wing 31 is installed, the third spring 36 is compressed. So when the wing 31 is disassembled, simply press the pressing plate 24 to drive the insertion rod 23 to be stored in the connecting cylinder 21. At this time, the elastic force of the third spring 36 pushes the wing 31 to move on the connecting cylinder 21 and automatically detach, thus making the disassembly of the wing 31 more convenient.

[0025] It is worth noting that, see Figure 2 and Figure 4 Guide grooves 22 are provided on both sides of the outer side of the connecting cylinder 21, and guide blocks 33 are fixedly connected to both sides of the inner cavity of the wing 31. The outer dimensions of the guide blocks 33 are adapted to the inner dimensions of the guide grooves 22. By connecting the guide blocks 33 and the guide grooves 22, not only can the speed at which the insertion rod 23 corresponds to the slot 34 be improved, but the stability of the connection between the wing 31 and the connecting cylinder 21 can also be improved.

[0026] It is worth noting that, see Figure 1 A support block 3 is installed on the outer side of the wing 31. The height of the support block 3 is adapted to the distance between the upper cover plate 11 and the lower cover plate 1. The support block 3 supports the wing 31 between the upper cover plate 11 and the lower cover plate 1, thereby improving the stability of the wing 31 during installation.

[0027] It is worth mentioning that, see Figure 3 A limiting frame 25 is fixedly connected to the outer side of the extrusion plate 24 inside the mounting plate 2. By setting the limiting frame 25, the resetting distance of the extrusion plate 24 can be limited.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
