[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] Please see Figure 1-4 The diagram shows a landing gear for a drone that ensures stable landing. It includes a support structure 1, which consists of two sets. The two sets of support structures 1 can be installed on both sides of the drone body. Each support structure 1 includes a rhomboid block 11 and four mounting tubes 12. Sleeves 14 are fixedly connected to two opposite corners of the front face of the rhomboid block 11 and to the other two opposite corners of the rear face of the rhomboid block 11. The four mounting tubes 12 are arranged in an X-shape. One end of each mounting tube 12 is installed inside the sleeve 14, and the other end is fixedly connected to a mounting plate 13. A mounting cavity 15 is opened at the center of the mounting plate 13. The two mounting plates 13 at the bottom are equipped with anti-vibration structures 2, and the mounting plate 13 at the top can be installed on the drone body with screws.
[0021] It is worth noting that the X-shaped distribution of the rhomboid blocks 11 and the mounting tubes 12 enhances the overall stability of the landing gear, making the drone land more smoothly and reducing the risk of damage caused by instability. Furthermore, the combination of the mounting tubes 12 and the sleeves 14 improves the overall assembly efficiency. If one component is damaged, it can be replaced in time to ensure the overall service life.
[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 One end of the construction tube 12 is slidably inserted into the inside of the sleeve 14. An inclined elastic clamping plate 16 is fixedly connected to the outer circular surface of the sleeve 14. An insertion rod 17 is fixedly connected to the inner side of the elastic clamping plate 16. The bottom end of the insertion rod 17 slides through the sleeve 14. A matching locking hole 102 is opened on the outer circular side of the insertion end of the construction tube 12.
[0023] Before the assembly tube 12 is fully inserted into the sleeve 14, manually lift the elastic clamp 16. The insertion rod 17, under the elastic force of the elastic clamp 16, is precisely inserted into the clamp hole 102, fixing the assembly tube 12 and the sleeve 14. This prevents the impact force generated when the UAV lands from causing the assembly tube 12 and the sleeve 14 to loosen or fall off, further enhancing the stability of the landing gear. At the same time, the setting of the elastic clamp 16 allows the insertion rod 17 to be easily inserted into or removed from the clamp hole 102, facilitating the installation or disassembly of the assembly tube 12 and improving the assembly and maintenance efficiency of the landing gear.
[0024] Please refer to Figure 4 An arc-shaped sliding rod 18 is fixedly connected to the inner wall of the sleeve 14. An arc-shaped sliding groove 101 is provided on the outer circular side wall of the insertion end of the assembly tube 12. The arc-shaped sliding rod 18 is slidably engaged inside the arc-shaped sliding groove 101. When the insertion rod 17 is engaged in the locking hole 102 to fix the assembly tube 12, the arc-shaped sliding rod 18 and the arc-shaped sliding groove 101 can limit and position the assembly tube 12, preventing the assembly tube 12 from rotating inside the sleeve 14, thus further improving the assembly efficiency. The sliding cooperation of the arc-shaped sliding rod 18 and the arc-shaped sliding groove 101 facilitates the quick installation or disassembly of the assembly tube 12 and the sleeve 14, further improving the assembly and maintenance efficiency of the landing gear.
[0025] See Figure 3 The sleeve 14 and the rhombus block 11 are integrally formed, and the mounting tube 12 is welded to the mounting plate 13, which enhances the connection strength between the sleeve 14 and the rhombus block 11, as well as the structural strength between the mounting tube 12 and the mounting plate 13, ensuring the overall stability of the landing gear. The setting of the rhombus block 11 makes the connection between the landing gear and the UAV body more stable, which can effectively disperse the impact force generated when the UAV lands and avoid damage to the UAV body. The rhombus block 11 and the sleeve 14 are made of plastic materials, and the mounting tube 12 is made of aluminum alloy materials. Plastic materials have the characteristics of light weight, corrosion resistance, and easy processing and molding, which can effectively reduce the overall weight of the landing gear. Aluminum alloy materials have the characteristics of low density, high strength, and good corrosion resistance, which allows the mounting tube 12 to have sufficient load-bearing capacity while adopting a lightweight design, which helps to improve the flight performance and endurance of the UAV.
[0026] See Figure 2 and Figure 4 The seismic-resistant structure 2 includes a cylindrical sleeve 21 and an elastic hemisphere 23. The cylindrical sleeve 21 is slidably fitted onto the outside of the mounting plate 13. An oblong cavity 24 is formed on the outer sidewall of the cylindrical sleeve 21. The mounting cavity 15 communicates with the oblong cavity 24, and a bolt 25 is inserted inside it. The other end of the bolt 25 is threaded with a nut 26. The elastic hemisphere 23 is fixedly connected to the bottom of the cylindrical sleeve 21. The elastic hemisphere 23 absorbs the vibrations generated during the landing of the UAV, further enhancing the seismic performance of the landing gear. The sliding fit between the cylindrical sleeve 21 and the mounting plate 13 allows the seismic-resistant structure 2 to adjust according to the... The drone's landing status is adaptively adjusted, improving the adaptability and stability of the landing gear. This allows for fine-tuning of the height of the cylindrical sleeve 21. The height adjustment is achieved through the cooperation of the waist-shaped cavity 24 and the bolt 25. The operator can loosen the nut 26, then move the bolt 25 up and down within the waist-shaped cavity 24 to adjust to the appropriate height. After that, the nut 26 is tightened again to fix the bolt 25, thus achieving precise fine-tuning of the height of the cylindrical sleeve 21. This design not only improves the flexibility and applicability of the landing gear but also helps ensure the smoothness of the drone's landing.
[0027] Please refer to Figure 2 The cylindrical sleeve 21 has two symmetrically arranged storage slots 22 on its outer circular sidewall. The storage slots 22 are connected to the waist-shaped cavity 24. The head of the bolt 25 and the nut 26 are both located in the storage slots 22. This design allows the bolt 25 and nut 26 to be stored in the storage slots 22 when not in use, avoiding the bolt 25 and nut 26 from protruding. The design of the storage slots 22 also keeps the landing gear appearance clean and smooth, which helps to reduce air resistance and ensure the flight efficiency of the UAV.
[0028] 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.
