Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a protective device for UAVs. Background Technology

[0002] In recent years, drone technology has rapidly gained popularity in fields such as aerial surveying and mapping, agricultural plant protection, logistics and transportation, and emergency rescue due to its advantages of high flexibility and wide range of applications. However, when drones operate in complex environments (such as sandstorms, rain and snow, strong winds, and tree branch scraping), their core components—especially the high-precision optical lenses (such as aerial cameras, lidar, and infrared sensors)—are highly susceptible to damage from external factors.

[0003] In the prior art, some drones physically isolate their lenses by adding fixed protective covers (such as transparent plastic shells). However, such designs have significant drawbacks. When used in high humidity environments, water vapor easily forms on the lens surface, affecting image clarity. Therefore, a protective device for drones is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a protective device for drones, which has the advantages of protecting the camera and ensuring its clarity during use, and solves the problem of poor protective effect of the protective cover in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for a drone, comprising a body, four arms on the body, a power propulsion unit for providing power at the top of each arm, and a camera and landing gear at the bottom of the body; the camera includes a gimbal camera fixedly mounted at the bottom of the body, a lens on the gimbal camera, and a protective component for protecting the mounting base outside the lens;

[0006] The bottom of the camera is provided with a mounting base, and a transmission component for transmission is provided inside the mounting base. The transmission component is connected to the protective component.

[0007] Furthermore, the protective component includes a protective cover that is rotatably mounted outside the mounting base, and a linkage gear is provided on the outside of the protective cover.

[0008] Furthermore, the transmission component includes a transmission motor installed inside the mounting base, and the output shaft of the transmission motor is fixedly connected to a transmission gear, which meshes with the linkage gear.

[0009] Furthermore, the protective cover is semi-circular and made of transparent acrylic material.

[0010] Furthermore, the protective cover is also provided with a protective shell for protection. The shell has mounting holes that are compatible with the protective cover. The shell covers the outside of the transmission gear and the linkage gear to achieve shielding.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] I. This protective device for drones, by incorporating protective components, provides excellent protection for the lens during use, thus preventing damage caused by external forces. By connecting the transmission component to the lens, it enables the transmission component to rotate, preventing rain, snow, or other impurities from adhering to the outer surface of the transmission component during lens protection, which could affect the clarity of the lens during shooting.

[0013] Second, this protective device for drones, by making the protective cover hemispherical and using transparent acrylic material, further reduces the adhesion of rain and snow during use. When rain and snow fall on the curved outer surface, they can quickly flow away. By using acrylic material, both transparency and good mechanical properties are ensured. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figure 1-4 This embodiment provides a protective device for a drone, comprising a body 1 with four arms 11. Each arm 11 has a power propulsion unit 12 at its top. A camera 2 for shooting is located at the bottom of the body 1. The camera 2 includes a gimbal camera 21 fixedly mounted at the bottom of the body 1, with a lens 23 on the gimbal camera 21. A protective element 24 for protecting a mounting base 22 is located outside the lens 23. A mounting base 22 is located at the bottom of the camera 2, and a transmission element 26 is installed inside the mounting base 22, which is connected to the protective element 24. In actual use, during rain or snow, the operator can control the transmission element 26 to rotate the protective element 24. During rotation, the rain and snow adhering to the protective element 24 are effectively shaken off by centrifugal force, thus ensuring the clarity of the image captured by the mounting base 22.

[0022] The technical effects of the above embodiments are as follows: by providing a protective component 24, the lens 23 can be well protected during use, thereby avoiding damage caused by external forces. By connecting the transmission component 26 to the lens 23, the transmission component 26 can be driven to rotate, thereby preventing rain, snow or other impurities from adhering to the outer surface of the transmission component 26 during the protection of the lens 23, which would affect the clarity of the lens 23 during the shooting process.

[0023] As a preferred technical solution in this embodiment: the protective component 24 includes a protective cover 241 rotatably mounted outside the mounting base 22, and a linkage gear 242 is provided on the outside of the protective cover 241. The transmission component 26 includes a transmission motor 261 installed inside the mounting base 22, and the output shaft of the transmission motor 261 is fixedly connected to the transmission gear 262, which meshes with the linkage gear 242. During use, the operator can control the output shaft of the transmission motor 261 to drive the transmission gear 262 to rotate. During the rotation of the transmission gear 262, the linkage gear 242 can be effectively driven to rotate, thereby driving the protective cover 241 to rotate. This allows the protective cover 241 to effectively shake off rain, snow, and other impurities adhering to its exterior, ensuring its protective effect during use and enabling the drone to adapt to rainy and snowy weather, thus guaranteeing its effectiveness in rainy and snowy weather.

[0024] As a preferred technical solution in this embodiment: the protective cover 241 is hemispherical and made of transparent acrylic material. By setting it to a hemispherical shape, it can further reduce the adhesion of rain and snow during use, and rain and snow can quickly flow away when they fall on the curved outer surface. By making it of acrylic material, both its transparency and good mechanical properties can be guaranteed.

[0025] As a preferred technical solution in this embodiment: the protective cover 241 is further provided with a protective shell 25 for protection. The shell 25 has mounting holes adapted to the protective cover 241, and the shell 25 covers the outside of the transmission gear 262 and the linkage gear 242 to achieve shielding. By providing the protective shell 25, the transmission gear 262 and the linkage gear 242 can be effectively protected, reducing the wear caused by dust or solid impurities adhering to the transmission gear 262 or the linkage gear 242 during use. Furthermore, in actual use, the linkage gear 242 and the transmission gear 262 can preferably be made of stainless steel or have a rust-proof coating to ensure that they can avoid corrosion in rainy weather and increase their durability during use.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
