The second drone support base 22 has a second connection mounting position 221, and the first drone support base 21 has a first connection mounting position 211. The second connection mounting position 221 is connected to the first connection mounting position 211, so that the second drone support base 22 can be detachably connected to the first drone support base 21 to improve the convenience of installation.

[0038] Specifically, the first UAV support base 21 is provided with a first UAV support plate 212 and a second UAV support plate 213. The first UAV support plate 212 and the second UAV support plate 213 are arranged opposite to each other to form the first connection mounting position 211 for connection with the second connection mounting position 221. The relative arrangement of the first UAV support plate 212 and the second UAV support plate 213 forms a precisely matched installation space between them, and the installation space is adapted to the shape and size of the second connection mounting position 221, thereby achieving a fast and accurate connection, effectively improving the efficiency and accuracy of UAV assembly, and reducing possible errors during the installation process.

[0039] Furthermore, the second drone support base 22 is provided with a second drone support base one 222 and a second drone support base two 223. The second drone support base one 222 and the second drone support base two 223 are connected to each other at the first connection mounting position 211 for fastening. In this embodiment of the invention, the second drone support base one 222 and the second drone support base two 223 are produced by injection molding. Preferably, each side of the drone is provided with one second drone support base one 222 and one second drone support base two 223. The two second drone support bases one 222 are diagonally connected at the first connection mounting positions 211 on both sides, and the two second drone support bases two 223 are diagonally connected at the first connection mounting positions 211 on both sides, so as to improve the stability of the drone during flight and improve the production convenience of the second drone support base one 222 and the second drone support base two 223.

[0040] Furthermore, the second UAV support base 1 222 and the second UAV support base 223 are respectively provided with second UAV support base mounting positions 1 2221 and 2231. The second UAV support base mounting positions 1 2221 and 2231 are connected to the first connecting mounting position 211 to form the second connecting mounting position 221. The second UAV support base mounting position 1 2221 is provided with a second UAV support base connecting half hole 1, and the second UAV support base mounting position 2231 is provided with a second UAV support base connecting half hole 2. The second UAV support base connecting half hole 1 and the second UAV support base connecting half hole 2 are connected to form a complete second UAV support base connecting hole 1, so that the second UAV support base 1 222 and the second UAV support base 223 can be connected through the second UAV support base connecting hole 1, improving the installation positioning accuracy and facilitating the fastening of the second UAV support base 22 to the first UAV support base 21 through the second connecting mounting position 221, thereby enhancing the stability after connection.

[0041] Furthermore, the second UAV support base 1 222 and the second UAV support base 223 are respectively provided with flight structure mounting positions 1 2222 and 2232. The flight structure mounting position 1 2222 is located at the other end of the second UAV support base 1 222, opposite to the second UAV support base mounting position 1 2221. The flight structure mounting position 2232 is located at the other end of the second UAV support base 223, opposite to the second UAV support base mounting position 2231. The UAV flight structure 3 is fastened to the flight structure mounting position 1 2222 or the flight structure mounting position 2232. This design allows the UAV flight structure 3 to be secured via the flight structure mounting positions 1 2222 and 2232. The drone flight structure 3 is securely connected to the second drone support 22, thereby stably mounting the drone flight structure 3 on the drone support 2, ensuring power transmission and control precision during flight, and improving flight stability and reliability. The flight structure mounting position 2222 is provided with a first flight structure connection hole and a second flight structure connection hole, with the second flight structure connection hole equidistantly surrounding the first flight structure connection hole. The drone flight structure 3 is provided with a flight structure connection seat 31, which has flight structure mating holes corresponding to the second flight structure connection holes, so as to secure the drone flight structure 3 to the flight structure mounting position 2222 through a first threaded connector, thereby improving the tightness of the connection of the drone flight structure 3.

[0042] The second flight structure mounting position 2232 is provided with a third flight structure connection hole and a fourth flight structure connection hole. The fourth flight structure connection hole is equidistantly arranged around the third flight structure connection hole, and the four flight structure connection holes correspond one-to-one with the flight structure mating holes, so as to fasten the UAV flight structure 3 to the second flight structure mounting position 2232 through the second threaded connector, thereby improving the tightness of the connection of the UAV flight structure 3.

[0043] Furthermore, the UAV support structure 2 is also provided with a first support stabilization structure 23 and a second support stabilization structure 24. The second UAV support base 1 222 and the second UAV support base 223 are also provided with a first support stabilization mounting part 2223 and a second support stabilization mounting part 2233. The first support stabilization structure 23 and the second support stabilization structure 24 are respectively connected to the first support stabilization mounting part 2223 and the second support stabilization mounting part 2233 to support the UAV, so as to ensure that the UAV can be stably docked on the ground after the flight, avoiding damage to the UAV by direct docking and improving the safety of UAV docking. At the same time, it ensures the levelness of the second UAV support base 1 222 and the second UAV support base 223 after connection, so as to reduce wear on the connection of the second UAV support base 1 222 and the second UAV support base 223, thereby extending the service life of the UAV.

[0044] Furthermore, the first support and stabilizing structure 23 is provided with a first support limiting groove 231 and a first support and stabilizing protrusion 232. The first support limiting groove 231 is provided with a first support limiting block 2311, and the support and stabilizing mounting part 2223 is provided with a support and stabilizing connecting hole 22231. The first support and stabilizing structure 23 is connected to the first support limiting block 2311 through the support and stabilizing connecting hole 22231, and then connected within the first support limiting groove 231 and supported by the first support limiting block 2311. This provides double limiting for the first support and stabilizing structure 23 through the first support limiting groove 231 and the first support limiting block 2311, thereby ensuring that the grounding stability of the first support and stabilizing structure 23 is enhanced when the first support and stabilizing protrusion 232 abuts against the ground. The contact area between the first support and stabilizing protrusion 232 and the ground is designed as a plane to increase the contact area between the first support and stabilizing protrusion 232 and the ground, thereby enhancing the grounding stability of the first support and stabilizing structure 23.

[0045] The second support and stabilizing structure 24 is provided with a second support limiting groove 241 and a second support and stabilizing protrusion 242. The second support limiting groove 241 is provided with a second support limiting block 2411. The second support and stabilizing mounting part 2233 is provided with a second support and stabilizing connecting hole 22331. The second support and stabilizing structure 24 is connected to the second support limiting block 2411 through the second support and stabilizing connecting hole 22331, and then connected in the second support limiting groove 241. It is supported by the second support and stabilizing protrusion 242, so that the second support and stabilizing structure 24 is doubly limited by the second support limiting groove 241 and the second support limiting block 2411, thereby ensuring that the second support and stabilizing protrusion 242 abuts the ground, thus enhancing the grounding stability of the second support and stabilizing structure 24. The contact area between the second support and stabilizing protrusion 242 and the ground is designed as a plane to increase the contact area between the second support and stabilizing protrusion 242 and the ground, thereby enhancing the grounding stability of the second support and stabilizing structure 24.

[0046] Furthermore, the drone provided in this embodiment of the invention also includes a main control module 4 for controlling the drone's flight and a waterproof layer for waterproofing. The drone shell 1 is connected to the first drone support plate 213 and forms a control structure mounting cavity. The first drone support plate 212 is disposed within the control structure mounting cavity. The second drone support base 222 and the second drone support base 223 are also provided with a second drone support base connecting groove 2224 and a second drone support base connecting groove 2234, which are respectively connected to the first flight structure connecting hole and the third flight structure connecting hole. The main control module 4 is connected to the first UAV support plate 212. The UAV flight structure 3, which is set on the second UAV support base 222 and the second UAV support base 223, is connected to the main control module 4 through connecting lines installed in the second UAV support base connecting cable grooves 2224 and 2234, respectively. The main control module 4 controls the rotation of the UAV flight structure 3, thereby driving the UAV to fly. This design, with the connecting lines installed in the second UAV support base connecting cable grooves 2224 and 2234, effectively improves the stability and safety of the UAV during operation.

[0047] The Pirilin waterproof layer is installed on the main control module 4 and the UAV flight structure 3 for waterproofing. In this embodiment of the invention, the Pirilin waterproof layer is vacuum coated using a Pirilin vacuum coating machine. Pirilin vacuum coating technology is an advanced process that uses parylene material for coating. Pirilin vacuum coating technology deposits and generates a polymer film on the surface of an object through chemical vapor deposition. The specific process includes three steps: vaporization, pyrolysis and polymerization. First, the raw material of Pirilin is vaporized at 150°C, then pyrolyzed into monomers at 650°C, and finally uniformly covered on the surface of the coated object by vapor deposition at room temperature. The entire Parylene vacuum coating process must be carried out under vacuum conditions to ensure uniform coating without dead corners, covering all parts of the object to be coated, including sharp edges, inside gaps, and extremely fine pinholes. This provides waterproof, moisture-proof, dustproof, and insulating protection for electronic components, thereby improving the reliability and lifespan of electronic products. In this embodiment of the invention, the main control module 4, the UAV flight structure 3, and the connecting lines are coated with a nano- to micron-sized Parylene waterproof layer using Parylene vacuum coating technology to enhance applicability to different UAV models, thereby improving the overall waterproof performance of the UAV and extending its lifespan.

[0048] Furthermore, the second drone support base 22 is also provided with connecting support members 226, and both the second drone support base 1 222 and the second drone support base 223 adopt an integral molding structure design to improve the convenience of separately producing the second drone support base 1 222 and the second drone support base 223 using injection molding process; the multiple connecting support members 226 are respectively connected to the second drone support base 1 222 and the second drone support base 223 for support, so as to avoid damage to the second drone support base 1 222 and the second drone support base 223 due to excessive local stress, thereby extending the service life of the second drone support base 1 222 and the second drone support base 223; in this embodiment of the invention, the connecting support members 226 are connected to the second drone support base 1 222 and the second drone support base 223 by glue connection to improve the convenience of connection.

[0049] In this embodiment of the invention, the drone shell 1 is provided with a drone side panel 11 and a GPS mounting position 12. The drone side panel 11 adopts a laser-engraved light-transmitting process, which can enhance the aesthetics and technological feel of the drone, thereby enhancing its market competitiveness. The GPS mounting position 12 is used to install a GPS device. The GPS device is electrically connected to the main control module 4 and is coated with a nano- to micron-level waterproof layer. The origin information can be preset through the main control module 4, so that the drone can automatically return to its home location through GPS positioning in case of an accident, thereby reducing losses.

[0050] The present invention also provides a method for waterproofing drones, for producing the Piriton waterproofing layer as described above, the method comprising the following steps:

[0051] S1. Cleaning: After SMT, the circuit board on the main control module 4 usually has residues such as flux and ink. These residues will affect the adhesion of the phenelzine. Therefore, the circuit board on the main control module 4 after SMT can be cleaned with any of the following cleaning agents: alcohol (such as methanol, ethanol, isopropanol, n-butanol), ether (such as tert-methyl ether, isopropyl ether, ethylene glycol monomethyl ether, ethylene glycol dimethyl ether), ester (such as ethyl acetate, isopropyl acetate, n-butyl acetate), or alkane (n-hexane, n-heptane, n-pentane) to improve the adhesion of the phenelzine during the coating process.

[0052] S2. Shielding: During the coating process, the pads and connectors on the circuit board of the main control module 4, the drone flight structure 3, drone components, connectors and interfaces will be covered, which may lead to poor connection or increased contact resistance. Before coating, one of the following should be used to shield the pads and connectors on the circuit board of the main control module 4, the drone flight structure 3, drone components, connectors and interfaces after cleaning, to ensure that the normal function and performance of all drone components are not affected after coating, and to enhance the connection stability of the drone after coating.

[0053] S3. Plasma Treatment: After shielding all components of the UAV, in order to effectively change the surface state of all components and increase the adhesion of the P-coating on their surfaces, the pads and connectors on the circuit board of the shielded main control module 4, the UAV flight structure 3, UAV components, connectors and interfaces are subjected to plasma treatment using a plasma treatment device. In this invention, argon, oxygen, hydrogen or a combination of argon / oxygen or argon / hydrogen is preferably used for plasma treatment. The treatment power is 300-600W and the treatment time is 100-600S to increase the adhesion of the P-coating on the surface of all components of the UAV.

[0054] S4. Coating: The solder pads and connectors on the circuit board of the plasma-treated main control module 4, the drone flight structure 3, drone components, connectors, and interfaces are placed in a Perylene vacuum coating machine for coating to form a nano- to micron-scale Perylene waterproof layer. In this embodiment of the invention, depending on the usage scenario of the drone under different conditions, the Perylene material can be selected as type C, type F, or type AF4, and the coating thickness can be selected as 10μm-30μm to enhance the applicability of the drone in different environments. Perylene type C: Perylene type C contains chlorine atoms, which gives it better moisture-proof and chemical corrosion-proof properties, effectively preventing moisture from penetrating the drone, and also resisting various chemical substances. With good tolerance, it helps extend the service life of drones in humid environments; Parylene F type: Parylene F type contains fluorine atoms, which gives it better chemical resistance and high temperature resistance, ensuring that drones maintain stable performance at higher temperatures, while also having excellent tolerance to a variety of chemicals, which helps extend the service life of drones in high-temperature environments; Parylene AF4 type: Parylene AF4 type contains fluorine and aromatic ring structures, which gives it even higher high temperature resistance and chemical resistance, ensuring that drones maintain stable performance at higher temperatures, while also having excellent tolerance to a variety of chemicals, which helps extend the service life of drones in high-temperature and harsh environments.

[0055] S5. Post-processing: Deshield the pads and connectors on the circuit board of the main control module 4, the UAV flight structure 3, the UAV components, connectors and interfaces after coating. Preferably, laser cutting, laser etching, or robotic adhesive removal is used for deshielding to ensure that the normal function and performance of the pads and connectors on the circuit board of the main control module 4, the UAV flight structure 3, the UAV components, connectors and interfaces after coating are not affected.
