Description

Technical Field

[0001] This application belongs to the technical field of drones, and particularly relates to a vertical takeoff and landing fixed-wing drone. Background Art

[0002] A drone, an unmanned aerial vehicle, is an unpiloted aircraft controlled by a radio remote control device and a self-contained program control device. It usually consists of a fuselage, wings, a power system, a control system, sensors, etc. Most of the existing small drones take off in a vertical takeoff and landing manner.

[0003] The existing utility model with the authorization announcement number CN216140170U discloses a vertical takeoff and landing fixed-wing drone, which is provided with a foldable wing device and a landing assistance device. When the drone is in the transportation process, the wing rod rotates into the inside of the storage groove through the cooperation of the connecting block and the rotating shaft for storage. At the same time, the second bolt is rotated upward to squeeze and fit with the bottom surface of the wing rod, fixing the wing rod inside the storage groove to prevent the wing rod from shaking inside the storage groove due to the vibration of the transport vehicle when driving on a bumpy road section. At the same time, the wing rod is clamped inside the adjustment grooves on the upper and lower sides of the connecting block through the clamping block to prevent the drone body from vibrating with the transport vehicle and causing the bolt slurry to collide with the inner wall surface of the storage groove, facilitating the storage of the wing device and strengthening the fixation of the wing device stored inside the storage groove.

[0004] Adopting the above technical solution, although the wings can be stored, thereby increasing the safety during the transportation process, the disassembly of the wings in the above technical solution is rather troublesome, lacking a quick disassembly and assembly structure for quickly disassembling the wings, resulting in time-consuming and laborious replacement when the wings are damaged and need to be replaced.

[0005] Therefore, we propose a vertical takeoff and landing fixed-wing drone to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve the problem in the prior art that it is time-consuming and laborious to replace the wings when they are damaged, and to propose a vertical takeoff and landing fixed-wing drone.

[0007] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0008] A vertical takeoff and landing fixed-wing unmanned aerial vehicle, comprising a main control body, two brackets are fixedly connected to the bottom surface of the main control body, four arms are arranged inside the main control body, a pull plate is arranged above the main control body, a motor is fixedly connected to the inner wall of each arm, a fan blade is arranged above each arm, a rotating rod is fixedly connected to the output end of each motor, a first electrode plate and a first magnetic disk are respectively fixedly connected to the inner wall of each arm, a limiting groove is formed in the upper surface of each arm, four second electrode plates and four second magnetic disks are respectively fixedly connected to the inner wall of the main control body, four guide rods are fixedly connected to the bottom surface of the pull plate, a limiting disk is fixedly connected to the bottom end of each guide rod, and a return spring is sleeved on the outer surface of each guide rod.

[0009] Preferably, the outer surface of each arm is in contact with the inner wall of the main control body, the bottom surface of the pull plate is in contact with the upper surface of the main control body, the top end of each rotating rod is fixedly connected to the bottom surface of the fan blade, the upper surface of each second electrode plate is in contact with the bottom surface of the first electrode plate, one side surface of each second magnetic disk close to the first magnetic disk is in contact with one side surface of the first magnetic disk close to the second magnetic disk, each motor is electrically connected to the first electrode plate through a wire, each second electrode plate is electrically connected to the main control body through a wire, the outer surfaces of the four guide rods and the outer surfaces of the four limiting disks are slidably connected to the inside of the main control body, the outer surface of each limiting disk is in contact with the inner wall of the limiting groove, both ends of each return spring are respectively in contact with the inner top wall of the main control body and the upper surface of the limiting disk, an anti-slip sleeve is fixedly connected to the outer surface of each arm, and a plurality of identical anti-slip convex columns are fixedly connected to the outer surface of each anti-slip sleeve.

[0010] Preferably, a coupling is fixedly connected to the outer surface of the output end of each motor, and the inner wall of each coupling is fixedly connected to the outer surface of the rotating rod.

[0011] Preferably, an auxiliary bearing is fixedly connected to the inner wall of each arm, and the inner ring of each auxiliary bearing is fixedly connected to the outer surface of the rotating rod.

[0012] Preferably, a handle support is fixedly connected to the upper surface of the pull plate, and a pull rod is fixedly connected to the inner wall of the handle support.

[0013] Preferably, a grip is arranged inside the handle support, and the inner wall of the grip is in contact with the outer surface of the pull rod.

[0014] In summary, the technical effects and advantages of this application:

[0015] By setting the main control body and the robotic arms, each robotic arm can be flexibly inserted and removed from the inside of the main control body. Pulling the pull plate can make the guide rod and the limit disk slide up and down inside the main control body. Then, after the robotic arm is inserted into the main control body, the second magnetic disk can stably attract and engage with the first magnetic disk. And under the resilience of the return spring, the limit disk can stably plug into the corresponding limit slot. At the same time, the docking of the first electrode plate and the second electrode plate can enable the main control body to flexibly control the power-on situation of each motor. Thus, the flight function of the composition structures such as the main control body and the robotic arms can be realized. As a result, the disassembly and assembly of each robotic arm relative to the main control body only require pulling the pull plate and inserting and removing each robotic arm, which can quickly disassemble each robotic arm and avoid the problem that it is time-consuming and laborious to replace the damaged wing due to the lack of a quick disassembly and assembly structure for quickly disassembling the wing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Refer to Figure 1-6, a vertical takeoff and landing fixed-wing UAV, comprising a main control body 1. Two brackets 2 are fixedly connected to the bottom surface of the main control body 1. Four arms 3 are arranged inside the main control body 1. A pull plate 11 is arranged above the main control body 1. A motor 4 is fixedly connected to the inner wall of each arm 3. The outer surface of each arm 3 is in contact with the inner wall of the main control body 1. The bottom surface of the pull plate 11 is in contact with the upper surface of the main control body 1. An anti-slip sleeve 15 is fixedly connected to the outer surface of each arm 3. A number of identical anti-slip convex columns 16 are fixedly connected to the outer surface of each anti-slip sleeve 15. By providing the anti-slip convex columns 16, the anti-slip property of the outer surface of the anti-slip sleeve 15 can be increased. By providing the anti-slip sleeve 15 and the anti-slip convex columns 16, the anti-slip property of the outer surface of the arm 3 can be increased together, thereby facilitating the grasping of the arm 3 and increasing the convenience of installing the arm 3 relative to the main control body 1.

[0025] A fan blade 6 is arranged above each arm 3. A rotating rod 5 is fixedly connected to the output end of each motor 4. The top end of each rotating rod 5 is fixedly connected to the bottom surface of the fan blade 6. A coupling 17 is fixedly connected to the outer surface of the output end of each motor 4. The inner wall of each coupling 17 is fixedly connected to the outer surface of the rotating rod 5. By providing the coupling 17, the connection between the output end of the motor 4 and the rotating rod 5 can be strengthened, thereby increasing the rotational stability of the rotating rod 5.

[0026] A first electrode plate 7 and a first magnetic disk 8 are respectively fixedly connected to the inner wall of each arm 3. A limiting groove 22 is formed in the upper surface of each arm 3. Each motor 4 is electrically connected to the first electrode plate 7 through a wire. An auxiliary bearing 18 is fixedly connected to the inner wall of each arm 3. The inner ring of each auxiliary bearing 18 is fixedly connected to the outer surface of the rotating rod 5. By providing the auxiliary bearing 18, the arm 3 and the rotating rod 5 can be connected, thereby increasing the rotational smoothness of the rotating rod 5.

[0027] Four second electrode plates 9 and four second magnetic disks 10 are respectively fixedly connected to the inner wall of the main control body 1. Four guide rods 12 are fixedly connected to the bottom surface of the pull plate 11. The upper surface of each second electrode plate 9 is in contact with the bottom surface of the first electrode plate 7. Each second electrode plate 9 is electrically connected to the main control body 1 through a wire. One side surface of each second magnetic disk 10 close to the first magnetic disk 8 is in contact with one side surface of the first magnetic disk 8 close to the second magnetic disk 10. A handle support 19 is fixedly connected to the upper surface of the pull plate 11. A pull rod 20 is fixedly connected to the inner wall of the handle support 19. By providing the pull rod 20, a rotating base surface can be provided for the hand-held structure in the handle support 19, thereby increasing the use flexibility of the hand-held structure.

[0028] The bottom end of each guide rod 12 is fixedly connected to a limit plate 13, and the outer surface of each guide rod 12 is sleeved with a return spring 14. The outer surfaces of the four guide rods 12 and the outer surfaces of the four limit plates 13 are slidably connected to the interior of the main control body 1, and the outer surface of each limit plate 13 is in contact with the inner wall of the limit groove 22. The two ends of each return spring 14 are respectively in contact with the inner top wall of the main control body 1 and the upper surface of the limit plate 13. A grip 21 is provided inside the handle support 19, and the inner wall of the grip 21 is in contact with the outer surface of the pull rod 20. By providing the grip 21, it can be rotated inside the handle support 19 and the outer surface of the pull rod 20, and there is a certain damping between the grip 21 and the pull rod 20. The grip 21 is not easy to rotate relative to the pull rod 20 without external force, thereby ensuring the relative stability of the entire UAV structure during flight.

[0029] The working principle of the utility model is: when in use, the main control body 1 is controlled by external remote control equipment to control the power supply of each motor 4 to drive the rotation of the rotating rod 5 and the fan blade 6, thereby controlling the flight state of the flight structure composed of the main control body 1 and the various structures of the arm 3. When it is necessary to splice each arm 3 with the main control body 1, first insert each arm 3 into a part of the inner part of the main control body 1, then hold the handle 21 and pull the pull plate 11 to make the guide rod 12 and the limit plate 13 slide upward inside the main control body 1, and at the same time, the main control body 1 and the limit plate 13 compress the return spring 14 to a certain extent, until each limit plate 13 leaves space for the corresponding arm 3 so that the second magnetic disk 10 can be close to and fit with the first magnetic disk 8, and then each second magnetic disk 10 is aligned with the corresponding first magnetic disk 8. The two arms 21 are connected and magnetically attracted to each other, and then the grip 21 is released. After that, the limit plate 13 is stably plugged into the corresponding limit groove 22 under the rebound of the return spring 14. At the same time, the docking of the first electrode plate 7 and the second electrode plate 9 enables the main control body 1 to flexibly control the power supply status of each motor 4, thereby realizing the flight function of the structure composed of the main control body 1 and the arm 3. When it is necessary to remove a certain arm 3 from the main control body 1, the above-mentioned process can be reversed. As a result, the disassembly and assembly of each arm 3 relative to the main control body 1 only requires pulling the pull plate 11 and plugging and unplugging each arm 3, which plays the role of quickly disassembling each arm 3. The design of the entire vertical take-off and landing fixed-wing UAV effectively solves the problem of the lack of a quick disassembly and assembly structure that can quickly disassemble the wing, which makes it time-consuming and labor-intensive to replace the wing when it is damaged.
