Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a wingspan control structure of an inspection unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicles, or UAVs for short, are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by onboard computers. Compared with manned aircraft, drones are often more suitable for tasks that are too "dull, dirty or dangerous". Drones can be divided into military and civilian applications according to their application areas. In the military, drones are divided into reconnaissance aircraft and target aircraft. In the civilian sector, drones + industry applications are the real rigid demand for drones; their applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the use of drones themselves, and developed countries are also actively expanding industry applications and developing drone technology.

[0003] Inspection UAVs often need to cross narrow spaces during inspection and monitoring missions. The wingspan of existing inspection UAVs does not have an adjustable function, which means that the adaptability of the UAV in different flight scenarios is poor. When it is necessary to change the flight performance or respond to emergencies, the lack of wingspan adjustment will limit the flexibility of the UAV and its performance in different flight missions. In view of the above problems, a wingspan control structure of an inspection UAV is proposed to solve them. Utility Model Content

When it is necessary to change the flight performance or respond to emergencies, the lack of wingspan adjustment will limit the flexibility of the drone and limit the performance of the drone in different flight missions.

[0005] To achieve the above objectives, the technical solution adopted by the utility model is: a wingspan control structure of an inspection unmanned aerial vehicle, including a body, a mounting groove is opened through the middle of the body, a wingspan control component is installed inside the mounting groove, and the wingspan control component includes a base, the base is fixedly connected to the left side wall of the mounting groove, the front and rear ends of the right side of the base are fixedly connected to guide rods, two second fixing seats are slidably connected to the surfaces of the two guide rods, the left and right sides of the two second fixing seats are fixedly connected to threaded seats, the right ends of the two guide rods are fixedly connected to the first fixing seats, the two first fixing seats are rotatably connected to the first connecting rods, the bottom of the first connecting rod is fixedly connected to the wing by a pin, the two second fixing seats are rotatably connected to the second connecting rods, and the end of the second connecting rod is rotatably connected to the middle part of the first connecting rod through a rotating shaft.

[0006] Preferably, a driving motor is fixedly installed on the right side inside the installation groove, and a threaded screw is fixedly connected to the output end of the driving motor. The left end of the threaded screw is rotatably connected to the right side of the base, and the middle parts of the two threaded seats are threadedly connected to the surface of the threaded screw.

DETAILED DESCRIPTION

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] Reference Figure 1-3 As shown, a wingspan control structure of an inspection unmanned aerial vehicle comprises a body 1, a mounting slot 2 is provided through the middle of the body 1, a wingspan control assembly 3 is installed inside the mounting slot 2, the wingspan control assembly 3 comprises a base 301, the base 301 is fixedly connected to the left side wall of the mounting slot 2, guide rods 304 are fixedly connected to the front and rear ends of the right side of the base 301, two second fixing seats 309 are slidably connected to the surfaces of the two guide rods 304, threaded seats 308 are fixedly connected to the left and right sides of the two second fixing seats 309, the right ends of the two guide rods 304 are fixedly connected to the first fixing seats 305, the two first fixing seats 305 are rotatably connected to the first connecting rod 306, the bottom of the first connecting rod 306 is fixedly connected to the wing 307 by a pin, the two second fixing seats 309 are rotatably connected to the second connecting rod 310, and the end of the second connecting rod 310 is rotatably connected to the middle part of the first connecting rod 306 through a rotating shaft.

[0020] Specifically, a driving motor 303 is fixedly installed on the right side inside the mounting groove 2, and a threaded screw 302 is fixedly connected to the output end of the driving motor 303. The left end of the threaded screw 302 is rotatably connected to the right side of the base 301. The middle parts of the two threaded seats 308 are threadedly connected to the surface of the threaded screw 302. The output end of the driving motor 303 is connected to the threaded screw 302 through a coupling, serving as a power source for adjusting the entire wingspan control assembly 3.

[0021] Specifically, the front and rear ends of the left side of the bottom of the machine body 1 are fixedly connected with the first supporting legs 4, and the ends of the two first supporting legs 4 are rotatably connected with the first casters 6.

[0022] Specifically, a second supporting leg 5 is fixedly connected to the right side of the bottom of the body 1, and second casters 7 are rotatably connected to the front and rear sides of the bottom of the second supporting leg 5. The arrangement of the first caster 6 and the second caster 7 allows the UAV to be easily moved and operated on the ground, facilitating takeoff, landing and ground operations. It can also serve as a buffer device for the landing of the UAV, reducing the impact force during landing and protecting the structure and load of the UAV.

[0023] Preferably, a plurality of tail wings 9 are fixedly connected to the left side of the fuselage 1. The design and adjustment of the tail wings 9 can affect the stability of the drone, making it more susceptible to external disturbances and able to quickly adjust itself and maintain a stable flight state.

[0024] The right side of the body 1 is rotatably connected to a propeller blade 8, which is a propulsion device of the UAV. The propeller blade 8 generates a propulsion force by rotating to push the UAV forward. The propeller blade 8 can also generate lift to help the UAV maintain its flight altitude in the air.

[0025] It is worth noting that the height of the mounting groove 2 is equal to the sum of the heights of the first connecting rod 306, the second connecting rod 310 and the wing 307. This design allows the first connecting rod 306, the second connecting rod 310 and the wing 307 to be stored in the mounting groove 2 when the wingspan is retracted, thereby reducing the space volume occupied and making it more convenient to transport.

[0026] Working principle: When adjusting the wingspan, the drive motor 303 drives the threaded screw 302 to rotate, so that the threaded seat 308 moves left or right along the threaded screw 302, and the threaded seat 308 drives the second fixed seat 309 to slide on the surface of the guide rod 304, so that the second connecting rod 310 pushes the first connecting rod 306 to rotate around the first fixed seat 305. The threaded seat 308 moves to the left and then realizes the counterclockwise rotation of the first connecting rod 306 to achieve the contraction of the wingspan. The threaded seat 308 moves to the right and then realizes the clockwise rotation of the first connecting rod 306 to achieve the expansion of the wingspan.

[0027] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
