Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to a structure for improving the wind resistance of UAVs. Background Technology

[0002] Improving the wind resistance of drones refers to optimizing the drone's aerodynamic shape, mechanical design, or control system to maintain stable flight performance in strong wind environments.

[0003] For example, Chinese patent CN222080918U discloses a variable-scale double-layer rotor structure for multi-rotor drones. The second rotor on the upper side of the device has a larger diameter, which can provide more lift during takeoff or when carrying heavy loads, allowing the drone to be flexibly adjusted according to specific flight requirements.

[0004] The drone has a large vertical cross-section, which results in greater wind resistance when it moves, thus reducing its wind resistance. Utility Model Content

[0005] The purpose of this utility model is to provide a structure that improves the wind resistance of drones, thereby solving the problems mentioned in the background art. It is installed on the drone body and includes:

[0006] The wind-resistant component includes two first fixed seats, which are fixedly installed on the drone body. A first connecting rod is rotatably connected inside the first fixed seat. A second fixed seat is rotatably connected to the end of the first connecting rod away from the first fixed seat. A wind guide plate is fixedly connected to the second fixed seat. The wind guide plates are V-shaped.

[0007] Preferably, the edges of the air guide plates that are close to each other are provided with bevels, which can make the air guide plates in close contact when they are in a V-shape.

[0008] Preferably, the first connecting rods are arranged in a figure-eight shape, and an adjustment component is installed on the drone body, which can change the angle between the air guide plates.

[0009] Preferably, the adjustment component includes:

[0010] The drive unit is fixedly mounted on the drone body;

[0011] The mounting plate is capable of being driven and moved by a drive mechanism;

[0012] Two third mounting brackets are fixedly mounted on the mounting plate;

[0013] Two second connecting rods are rotatably connected to the third fixed base;

[0014] Two fourth fixed seats are rotatably connected to the end of the second connecting rod away from the third fixed seat, and the two fourth fixed seats are fixed to the air guide plate respectively.

[0015] Preferably, the driving component is an electric telescopic rod.

[0016] Preferably, the second connecting rods are V-shaped.

[0017] Preferably, the fourth fixing seat is installed near the inclined plane.

[0018] Preferably, the second fixing seat is installed at a position away from the inclined plane.

[0019] Preferably, the adjustment assembly is disposed between the first links.

[0020] Preferably, the mounting plate and the output end of the electric telescopic rod are fixed together.

[0021] This application utilizes a V-shaped wind deflector to guide wind force, reducing wind resistance during drone movement. Simultaneously, a drive mechanism moves a mounting plate, which in turn moves a third fixed base. The third fixed base then moves a second linkage. Since the second linkage has a fixed length, it moves a fourth fixed base, which in turn pushes the wind deflector to rotate via the second fixed base. This changes the angle between the wind deflectors. When the wind deflectors are parallel, vortices are prevented from concentrating near the fan blades, thus making the drone more stable in weak or no wind conditions. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0032] To improve the wind resistance of drones, this embodiment provides a structure to enhance the wind resistance of drones, such as... Figure 1 and Figure 2 As shown, it is installed around the drone body 100 (existing technology, which includes a circular fuselage at the center and four wings surrounding the circular fuselage), and includes: a wind-resistant component 200, which guides wind force to reduce wind resistance.

[0033] Wind-resistant component 200 (e.g.) Figure 3 (As shown) includes two first fixing seats 210 (as shown) Figure 4 As shown, it consists of two symmetrical first plates, each with a first circular hole inside. The two first fixing seats 210 are respectively fixedly installed on the top surface of the UAV body 100 (e.g., Figure 1 (as shown) and bottom surface (as shown) Figure 2 As shown), the first connecting rod 220 is rotatably connected inside the first fixed base 210 (as shown). Figure 4 As shown, it has a first pivot at both ends, which is inserted into the first circular hole of the first plate to complete the rotational connection. At this time, the first connecting rods 220 are parallel to each other, and the first connecting rods 220 are supported by the UAV to maintain stability. The end of the first connecting rod 220 away from the first fixed seat 210 is rotatably connected to the second fixed seat 230 (e.g., Figure 6 As shown, it consists of two symmetrical second plates. The second plates have a second circular hole inside. The first shaft of the first connecting rod 220 is inserted into the second circular hole of the second plate to complete the rotational connection. The second fixed seat 230 is fixedly connected to the air guide plate 240 (rectangular). The air guide plates 240 are V-shaped.

[0034] In use, the V-shaped wind deflector 240 guides the wind force, thereby reducing the wind resistance of the drone body 100 during movement.

[0035] In actual use, when the drone is used in low wind or windless environments, it will sway slightly during movement. Although the wind deflector 240 can guide the wind and reduce wind resistance, when the wind is guided to the edge of the wind deflector 240, eddies are generated due to the concentration of wind force. These eddies are concentrated near the drone's fan blades and affect the drone's movement. To solve this problem, another solution is... Figure 5 As shown, the edges of the close-to-each sides of the air guide plates 240 are provided with inclined surfaces 241 (at a 45° angle with the larger surface of the air guide plate 240). These inclined surfaces 241 allow the air guide plates 240 to be in close contact when they form a V-shape (45°) with each other, while also keeping them separated from each other. Figure 3 As shown, the first connecting rods 220 are arranged in a V-shape (it should be emphasized that the V-shape of the first connecting rods 220 needs to be fixed at this time, otherwise the first connecting rods 220 will not be able to maintain the V-shape due to gravity shifting downwards, because the angle between the air guide plates 240 needs to be adjusted later, that is, at this time the first connecting rods 220 are fixed to the top and bottom of the drone respectively and are in a V-shape). Figure 6 As shown, the second fixing base 230 is installed at a position away from the inclined plane 241. Figure 7 As shown, an adjustment assembly is installed on the drone body 100. This assembly is positioned between the first connecting rods 220 and can change the angle between the air guide plates 240, thereby adjusting the air guide plates 240 to a parallel state. This prevents vortices from concentrating near the fan blades, making the drone more stable. Specifically, the adjustment assembly includes: a drive component 250, a mounting plate 260, two third fixing seats 270, two second connecting rods 280, and two fourth fixing seats 290.

[0036] The driving component 250 is an electric telescopic rod, which is fixedly mounted on the UAV body 100; the mounting plate 260 (square) can be driven and moved by the driving component 250, and the mounting plate 260 is fixed to the output end of the electric telescopic rod; two third fixing seats 270 (e.g. Figure 7 As shown, it consists of two symmetrical third plates (each third plate has a third circular hole inside), and the third fixing seat 270 is fixedly installed on the mounting plate 260; two second connecting rods 280 (as shown) Figure 7 As shown, its two ends have second rotating shafts, which are inserted into the third circular holes of the third plate to complete the rotational connection) and are respectively rotatably connected in the third fixed seat 270. The second connecting rod 280 is V-shaped; the two fourth fixed seats 290 (as shown) Figure 6As shown, it consists of two symmetrical fourth plates. The fourth plate has a fourth circular hole inside. The second shaft of the second connecting rod 280 is inserted into the fourth circular hole of the fourth plate to complete the rotational connection. The second shaft is rotatably connected to the end of the second connecting rod 280 away from the third fixed seat 270. The two fourth fixed seats 290 are fixed to the air guide plate 240 respectively. The fourth fixed seats 290 are installed near the inclined surface 241.

[0037] When the angle between the air guide plates 240 needs to be adjusted, the drive unit 250 is activated to move the mounting plate 260, which in turn moves the third fixed seat 270. The third fixed seat 270 then moves the second connecting rod 280. Since the length of the second connecting rod 280 is fixed, it will move the fourth fixed seat 290. The fourth fixed seat 290 will push the air guide plates 240 to rotate with the help of the second fixed seat 230, thereby changing the angle between the air guide plates 240. When the air guide plates 240 are parallel, vortices will not be generated near the fan blades, thus making the drone more stable in weak wind or no wind conditions.
