[0001] The utility model relates to the technical field of unmanned aerial vehicles, and more specifically, to a large-load unmanned aerial vehicle. Background Art

[0002] A large-load unmanned aerial vehicle is an unmanned aerial vehicle system capable of carrying a relatively large load. It usually has a relatively powerful power system and stable flight control ability, and can carry goods, equipment or sensors for flight missions. However, the prior art has the following deficiencies in use:

[0003] When some unmanned aerial vehicles lift goods, they use a hanging rope and a hook to lift the goods. During the flight of the unmanned aerial vehicle, the goods will swing under the influence of wind, which will affect the stability of the unmanned aerial vehicle during flight, have a certain safety hazard, and have relatively low practicability.

[0004] Therefore, there is an urgent need for a large-load unmanned aerial vehicle to solve the above problems. Summary of the Invention

[0005] The purpose of the utility model is to address the problem that when some existing unmanned aerial vehicles lift goods, they use a hanging rope and a hook to lift the goods. During the flight of the unmanned aerial vehicle, the goods will swing under the influence of wind, which will affect the stability of the unmanned aerial vehicle during flight, have a certain safety hazard, and have relatively low practicability.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A large-load unmanned aerial vehicle to improve the above problems.

[0008] Specifically, this application is as follows:

[0009] A large-load unmanned aerial vehicle, including an unmanned aerial vehicle body. A symmetrically distributed mounting plate is fixedly connected to the bottom of the unmanned aerial vehicle body. A bearing box is fixedly connected to the bottoms of the two mounting plates together. A guiding sliding groove is formed in the mounting plate. A connecting plate is slidably connected in the guiding sliding groove. One end of the connecting plate is fixedly connected to a clamping plate. A fixing plate is fixedly connected to the front of the mounting plate. A rectangular opening is formed in the fixing plate. A threaded rod is fixedly connected to the front of the connecting plate away from the clamping plate. A threaded positioning sleeve is threadedly sleeved on the threaded rod. Symmetrically distributed connecting ears are fixedly connected to the threaded positioning sleeve. A rigid rubber pad is fixedly connected to the front of the fixing plate.

[0010] As a preferred technical solution of this application, a polyurethane anti-slip coating is applied to the clamping plate.

[0011] As a preferred technical solution of this application, the threaded rod is located in the rectangular opening.

[0012] As a preferred technical solution of the present application, the width of the rectangular opening is greater than the diameter of the threaded rod.

[0013] As a preferred technical solution of the present application, the clamping plate is attached to the mounting plate.

[0014] As a preferred technical solution of the present application, the clamping plate is attached to the fixing plate.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the solution of the present application:

[0017] 1. Place the goods to be transported in the carrying box, then push the two connecting plates towards each other. The two clamping plates move respectively following the two connecting plates, and the distance between the two clamping plates decreases. After the two clamping plates are both attached to the goods, the operator rotates the two threaded positioning sleeves through the connecting ears so that the threaded positioning sleeves are in close contact with the hard rubber pads. Through the cooperation of the threaded positioning sleeves and the hard rubber pads, the positions of the connecting plates are fixed, and the two clamping plates are also fixed accordingly.

[0031] Embodiment 1

[0032] As Figures 1-5As shown in the figure, a large-load drone proposed in this embodiment includes a drone body 1. A symmetrically distributed mounting plate 2 is fixedly connected to the bottom of the drone body 1. A bearing box 3 is fixedly connected to the bottoms of the two mounting plates 2. An operator places the goods to be transported in the bearing box 3, making the goods located at the middle position inside the bearing box 3. A guiding chute 4 is provided on the mounting plate 2. A connecting plate 5 is slidably connected in the guiding chute 4. By pushing the two connecting plates 5 towards each other, one end of the connecting plate 5 is fixedly connected to a clamping plate 6. The two clamping plates 6 move along with the two connecting plates 5 respectively, and the distance between the two clamping plates 6 decreases. A fixing plate 7 is fixedly connected to the front of the mounting plate 2. A rectangular opening 8 is provided on the fixing plate 7. One end of the connecting plate 5 away from the clamping plate 6 on the front is fixedly connected to a threaded rod 9. A threaded positioning sleeve 10 is threadedly sleeved on the threaded rod 9. Symmetrically distributed connecting ears 11 are fixedly connected to the threaded positioning sleeve 10. After the two clamping plates 6 are both in contact with the goods, the operator rotates the two threaded positioning sleeves 10 through the connecting ears 11. A hard rubber pad 12 is fixedly connected to the front of the fixing plate 7, making the threaded positioning sleeve 10 closely fit with the hard rubber pad 12. Through the cooperation of the threaded positioning sleeve 10 and the hard rubber pad 12, the position of the threaded rod 9 in the rectangular opening 8 is fixed, and thus the positions of the two connecting plates 5 and the two clamping plates 6 are also fixed. The goods in the bearing box 3 are clamped and limited by the two clamping plates 6.

[0033] As Figure 1 and Figure 2 shown in the figure, a polyurethane anti-slip coating 13 is applied on the clamping plate 6. By providing the polyurethane anti-slip coating 13, the friction between the clamping plate 6 and the goods can be increased, preventing the goods from sliding in the bearing box 3 when the drone body 1 flies subsequently, and ensuring the stability and safety during the process of the drone body 1 transporting the goods.

[0034] As Figure 4 shown in the figure, the threaded rod 9 is located in the rectangular opening 8, and the threaded rod 9 moves along with the connecting plate 5.

[0035] As Figure 4 shown in the figure, the width of the rectangular opening 8 is greater than the diameter of the threaded rod 9. When the connecting plate 5 is moved, the threaded rod 9 will not contact the fixing plate 7.

[0036] As Figure 2 shown in the figure, the clamping plate 6 is in contact with the mounting plate 2.

[0037] As Figure 1 and Figure 2 shown in the figure, the clamping plate 6 is in contact with the fixing plate 7.

[0038] Specifically, when this large-load drone is in use: The operator places the goods to be transported in the carrying box 3, making the goods located at the middle position inside the carrying box 3. Then, the operator pushes the two connecting plates 5 towards each other. The two clamping plates 6 move respectively following the two connecting plates 5, and the distance between the two clamping plates 6 decreases. After the two clamping plates 6 are both in contact with the goods, the operator rotates the two threaded positioning sleeves 10 through the connecting ears 11, making the threaded positioning sleeves 10 closely fit with the hard rubber pads 12. Through the cooperation of the threaded positioning sleeves 10 and the hard rubber pads 12, the position of the threaded rod 9 inside the rectangular opening 8 is fixed. Consequently, the positions of the two connecting plates 5 and the two clamping plates 6 are also fixed accordingly. The goods inside the carrying box 3 are clamped and limited by the two clamping plates 6. Through the provided polyurethane anti-slip coating 13, the friction between the clamping plates 6 and the goods can be increased, preventing the situation where the goods shake and shift inside the carrying box 3 during the subsequent flight of the drone body 1, and ensuring the stability and safety during the process of the drone body 1 transporting goods. In this application, the model of the drone body 1 is: LB-H200.

[0039] The above embodiments are only used to illustrate the present invention rather than to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement to the present invention; and all technical solutions and their improvements that do not deviate from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
