However, existing drone designs often suffer from problems such as complex airframe structures and heavy weight, which limit the payload capacity and endurance of drones. In addition, the complex airframe structure not only increases the weight of the drone but also increases its manufacturing cost. Therefore, it is necessary to design a high-payload drone to solve the above technical problems. Utility Model Content

The support mainboard also has four symmetrically arranged support rods in pairs. Above the support mainboard are opposing first and second fixing plates, which are fixedly connected to the support rods. A first mounting cavity is formed between the first and second fixing plates, and a second mounting cavity is formed between the second fixing plate and the support mainboard. The first mounting cavity is used to install a power module, and the second mounting cavity is used to install an electronic control module. Below the support mainboard is a positioning seat connected to an I-shaped support frame, which is used to connect to a storage box.

[0010] Figure 1 This is a schematic diagram of the overall structure of the equipment. Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0012] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0013] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0014] To solve the above technical problems, such as Figure 1As shown, this utility model designs a large-payload unmanned aerial vehicle (UAV), including a support mainboard 1. The support mainboard 1 has four cantilever arms, each with a rotor 2 mounted on it. The four-rotor structure ensures flight stability. The support mainboard 1 has four symmetrically arranged support rods 3. Above the support mainboard 1 are opposing first fixing plates 4 and second fixing plates 5, which are fixedly connected to the support rods 3. A first mounting cavity 6 is formed between the first fixing plates 4 and the second fixing plates 5, and a second mounting cavity 7 is formed between the second fixing plate 5 and the support mainboard 1. The first mounting cavity 6 is used to install a power module, and the second mounting cavity 7 is used to install an electronic control module. The fixed connection between the support rods 3 and the first and second fixing plates 4 and 5 provides structural stability. Simultaneously, the formed mounting cavities provide dedicated installation space for the power module and electronic control module, facilitating installation and maintenance of each module. The compact layout simplifies the airframe structure, reduces weight, and lowers manufacturing costs.

[0015] A positioning seat 8 is provided below the supporting motherboard 1. The positioning seat 8 is connected to an I-shaped support frame 9. The I-shaped support frame 9 is used to connect with the storage box 10. Specifically, hooks 11 are provided on the outer sides of the front and rear crossbars of the I-shaped support frame 9. Hanging ropes are provided on the front and rear sides of the storage box 10. The storage box 10 is hung on the hooks 11 by the hanging ropes. The design of the hooks 11 allows the drone to easily hang the storage box 10 or other equipment. This design makes the drone more flexible during transportation and carrying. The storage box 10 can be easily and quickly docked or disassembled, improving efficiency.

[0016] In this embodiment, it is further preferred that the hook 11 is provided with a Velcro female sticker 12, and the crossbar of the I-shaped support frame 9 is provided with a Velcro female sticker that matches the Velcro female sticker 12. When the Velcro female sticker 12 and the Velcro female sticker are attached together, the opening of the hook 11 can be closed, thereby providing a more secure fixation effect and preventing the hung items from accidentally falling off during flight. Users only need to align the Velcro and press it together to quickly lock the lanyard. When it is necessary to unload, the lanyard can be easily removed by simply tearing open the Velcro, which improves the efficiency of operation.

[0017] In this embodiment, it is further preferred that a support column 13 is provided at each of the four corners of the I-shaped support frame 9, and a rectangular pad 14 is provided at the bottom of each support column 13. The pad 14 increases the contact area at the bottom of the support column 13, which helps to distribute the weight of the UAV during landing, reduce the pressure on the ground, and thus improve the stability of landing. The pad 14, as a buffer layer between the UAV and the ground, can reduce the impact on the ground during landing, reduce the structural damage to the UAV caused by hard landing, and improve landing safety.

[0018] It is worth noting that the technical features of rotor, power module, electronic control module and other related technologies involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and control method and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0019] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
