Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) fan blades, in particular to a wind-resistant wing for a UAV. Background Art

[0002] Unmanned aerial vehicle (UAV) is a small aircraft that can be controlled by remote control. Nowadays, it is generally controlled manually to achieve the effect of high-altitude photography. Sometimes people also use UAVs to explore places that are difficult for people to reach. When people use UAVs for shooting, they often need the UAVs to hover in the air. Therefore, UAVs need to have good wind resistance.

[0003] Some existing UAV wind-resistant wings usually install wind guide rings on the surface of the fan blades to protect the fan blades, diverting wind from all sides to reduce the resistance of the UAV. However, most wind-resistant fan blades are directly fixed on the fan blade connecting shaft. Therefore, if the wind-resistant cover is damaged, it is cumbersome to replace it, and its use has certain limitations. Utility Model Content

[0008] In some embodiments, the windproof mechanism includes a windproof cover, a sliding groove is provided under the windproof cover, and the windproof cover is plug-connected to the limit block through the sliding groove.

[0009] In some embodiments, a spring is provided at the outer end of the T-bar, and both ends of the spring are fixedly connected to the limit block, so that the limit block and the slide groove are always in a plug-in state, while preventing the limit block from shaking and improving the stability of the fixation.

[0011] In some embodiments, the plug-in components are provided in multiple groups and are evenly arranged around the windshield to improve the fixing effect. At the same time, the windshield is fixed in multiple directions to improve product stability.

[0012] In some embodiments, a pulling rod is provided inside the moving block, and the multiple pulling rods are interconnected, so that when we pull the pulling rod, multiple plug-in components can be driven to simultaneously remove or fix the windshield.

[0013] (3) Beneficial effects

[0014] Compared with the existing technology, the utility model provides a wind-resistant wing for a UAV, which has the following beneficial effects:

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0026] Combine Figures 1-6 , an embodiment of the present application provides a wind-resistant wing for a drone, comprising a drone body 1; a plurality of connecting shafts 2 are fixedly connected around the drone body 1, and the ends of the connecting shafts 2 are rotatably connected to fan blades 3; it is characterized in that: a plug-in assembly 4 is also provided on the connecting shaft 2, and the plug-in assembly 4 includes a support seat 41, a T-shaped rod 42 is provided on the support seat 41, a moving block 43 is slidably connected to the T-shaped rod 42, and the two sides of the moving block 43 are rotatably connected to connecting rods 44, and the other end of the connecting rod 44 is rotatably connected to a limiting block 45, and the limiting block 45 is slidably connected to the T-shaped rod 42, and a windproof mechanism 5 is slidably connected to the limiting block 45.

[0027] During use, we start the drone body 1 and transmit power to the fan blades 3 through the connecting shaft 2, so that the fan blades 3 rotate to control the flight of the drone. During the flight, if the windproof mechanism 5 is damaged, we can pull down the moving block 43 in the plug-in assembly 4 to make the limit block 45 retract on the T-bar 42 through the connecting rod 44 to cancel the connection of the windproof mechanism 5. Then the windproof mechanism 5 can be disassembled. After the new windproof mechanism 5 is installed, the moving block 43 can be moved up to push the limit block 45 out through the connecting rod 44 to complete the connection of the windproof mechanism 5, making replacement more convenient and quick, thereby improving the practicality of the product.

[0028] Specifically, the UAV controls the rotation of the fan blades to generate lift through the drive member provided in the UAV body 1 and the rotor and stator installed in the connecting shaft to control the flight of the UAV.

[0029] In some embodiments, the windproof mechanism 5 includes a windproof cover 51 , a sliding groove 52 is provided below the windproof cover 51 , and the windproof cover 51 is plug-connected to the limit block 45 through the sliding groove 52 .

[0030] During use, when we control the movement of the limit block 45 in the plug-in assembly 4, the limit block 45 will move in the slide groove 52 opened under the wind shield 51. When the connecting rod 44 on the limit block 45 moves to be close to the T-shaped rod 42, the limit block 45 will slide out of the slide groove 52, and the fixation of the wind shield 51 can be cancelled. Similarly, when the limit block 45 moves to the two ends of the slide groove 52, they will be plugged into each other to fix the wind shield 51.

[0031] In some embodiments, a spring 6 is provided at the outer end of the T-bar 42, and both ends of the spring 6 are fixedly connected to the limit block 45, so that the limit block 45 and the slide groove 52 are always in a plug-in state, while preventing the limit block 45 from shaking and improving the stability of the fixation.

[0032] In some embodiments, a protective shell 7 is provided on the outside of the T-shaped rod 42 , and the protective shell 7 wraps the spring 6 . A fixed ring 71 is fixedly connected to the outside of the limit block 45 , and the connecting rod 44 is rotatably connected to the fixed ring 71 .

[0033] When in use, the protective shell 7 will wrap the spring 6 and the T-bar 42 to prevent the spring 6 from being directly exposed to the outside and affecting its service life. At the same time, the fixed ring 71 can make the moving block 43 abut against the protective shell 7 when we move it, preventing the spring 6 from excessively shrinking and losing its elasticity.

[0034] In some embodiments, the plug-in components 4 are provided in multiple groups and are evenly arranged around the wind shield 51 to improve the fixing effect. At the same time, the wind shield 51 is fixed in multiple directions to improve product stability.

[0035] In some embodiments, a pulling rod 8 is provided inside the moving block 43 , and the multiple pulling rods 8 are interconnected, so that when we pull the pulling rod 8 , multiple plug-in components can be driven to simultaneously remove or fix the windshield 51 .

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
