[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A drone landing gear includes a mounting plate 1, a servo motor 2 fixedly connected to the bottom of the mounting plate 1, an adjustment disk 3 fixedly connected to the bottom of the servo motor 2, and an adjustment assembly 4 fixedly connected to the bottom of the adjustment disk 3.

[0027] The adjustment assembly 4 includes a hollow plate 401, a motor 402 is bolted to the right side of the hollow plate 401, a bidirectional threaded rod 403 is fixedly connected to the left side of the motor 402, an adjustment groove 404 is provided at the bottom of the hollow plate 401, two adjustment blocks 405 are threadedly connected to the surface of the bidirectional threaded rod 403, and two support frames 406 are fixedly connected to the bottom of the two adjustment blocks 405.

[0028] In this embodiment: A mounting plate 1 is used to fix the entire structure to the bottom of the UAV, providing a mounting base for all subsequent components. A servo motor 2 provides rotational power, which drives the adjustment plate 3 at the bottom to rotate, thereby adjusting the orientation of the adjustment component 4 and the support frame 406 to adapt to different landing angles or ground environments. The adjustment plate 3 connects the servo motor 2 and the adjustment component 4, receiving the rotational power of the servo motor 2 and transmitting it to the adjustment component 4, achieving overall orientation adjustment of the adjustment component 4. The adjustment component 4, the core adjustment structure of the landing gear, includes sub-components such as a hollow plate 401 and a motor 402. Its main function is to adjust the distance between the two support frames 406. The hollow plate 401 serves as the frame carrier for the adjustment component 4, used to install components such as the motor 402 and the bidirectional threaded rod 403, while also providing support for the movement of the adjustment block 405. To provide space, a motor 402 is installed to provide power for spacing adjustment. After starting, it drives the bidirectional threaded rod 403 to rotate, causing the adjusting block 405 to move. The bidirectional threaded rod 403 has reverse threads on its surface and is threadedly connected to the two adjusting blocks 405. When rotating, it can drive the two adjusting blocks 405 to move closer or further away synchronously, realizing the spacing adjustment of the support frame 406. An adjustment groove 404 is provided at the bottom of the hollow plate 401 to provide a channel for the movement of the adjusting block 405 and limit the movement trajectory of the adjusting block 405. The adjusting block 405 is connected to the bidirectional threaded rod 403 and the support frame 406. As the bidirectional threaded rod 403 rotates, it moves along the adjustment groove 404, thereby driving the support frame 406 to adjust its position. The support frame 406 supports the main body and connects to the buffer and grounding components at the bottom to support the weight of the UAV fuselage during take-off, landing and parking.

[0029] Specifically, such as Figure 3 As shown, two bolted plates 5 are bolted to the surface of the hollow plate 401, and a storage rod 6 is bolted to one side of the two bolted plates 5 opposite to each other. Two extension rods 7 are movably connected to the inner wall of the storage rod 6.

[0030] Specifically, such as Figure 3 As shown, the two extension rods 7 are fixedly connected to the inner sides of the two support frames 406 on opposite sides. The top of each of the two extension rods 7 is fixedly connected to an auxiliary block 8. The top of the inner wall of each of the two storage rods 6 is provided with an auxiliary groove 9 that works in conjunction with the auxiliary block 8.

[0031] Specifically, such as Figure 3 As shown, auxiliary frames 10 are fixedly connected to the left and right sides of the bolt plate 5, and both auxiliary frames 10 are bolted to the surface of the storage rod 6.

[0032] In this embodiment: A bolted plate 5 is fixed to the surface of the hollow plate 401, serving as the mounting carrier for the storage rod 6. By bolting it to the storage rod 6, the storage rod 6 is stably fixed to the adjusting assembly 4. The storage rod 6 has a hollow internal structure to house the extension rod 7, allowing it to extend and retract with the movement of the support frame 406, thus helping to maintain the stability of the support frame 406 during movement. The extension rod 7 has one end connected to the support frame 406 and the other end movably placed inside the storage rod 6, extending and retracting within the storage rod 6 as the support frame 406 moves, enhancing the structural stability of the support frame 406 during spacing adjustments. To prevent the support frame 406 from wobbling, an auxiliary block 8 is fixed to the top of the extension rod 7 and cooperates with the auxiliary groove 9 of the storage rod 6 to limit the movement trajectory of the extension rod 7 within the storage rod 6, preventing the extension rod 7 from detaching from or deviating from the storage rod 6. The auxiliary groove 9 is set at the top of the inner wall of the storage rod 6 and is adapted to the auxiliary block 8 to provide a movement channel for the auxiliary block 8, further ensuring the stability of the extension rod 7 during extension and retraction. An auxiliary frame 10 is set to connect the bolt plate 5 and the storage rod 6, forming additional support for the storage rod 6, enhancing the firmness of the connection between the storage rod 6 and the bolt plate 5, and preventing the storage rod 6 from deforming under stress.

[0033] Specifically, such as Figure 4 As shown, the bottom of each of the two support frames 406 is provided with a groove 11, the top of the inner wall of each of the two grooves 11 is fixedly connected with a spring 12, and the bottom of each of the two springs 12 is fixedly connected with an adjusting plate 13 that is movably connected to the groove 11.

[0034] Specifically, such as Figure 4 As shown, the bottom of each of the two adjustment plates 13 is fixedly connected to a base plate 14, and the bottom of each of the two base plates 14 is fixedly connected to an anti-slip plate 15.

[0035] In this embodiment: a groove 11 is provided at the bottom of the support frame 406 to provide installation space for the spring 12 and the adjusting plate 13, while limiting the range of movement of the adjusting plate 13 to prevent it from shifting. The spring 12 is placed in the groove 11, connecting the top of the groove 11 to the adjusting plate 13. During takeoff and landing, it absorbs the impact force from the ground through its own elastic deformation, playing a buffering and shock-absorbing role and protecting the drone fuselage and internal components. The adjusting plate 13 connects the spring 12 to the base plate 14 and can move up and down within the groove 11. The base plate 14 receives the buffering force of the spring 12 and transmits it to the base plate 14. It also adapts to different ground flatness to ensure that the base plate 14 is stably grounded. By setting the base plate 14 and fixing it to the bottom of the adjustment plate 13, the contact area between the landing gear and the ground is increased, the pressure of the drone on the ground is reduced, and the drone is prevented from sinking on soft ground. At the same time, it provides a mounting base for the anti-slip plate 15. By setting the anti-slip plate 15 and fixing it to the bottom of the base plate 14, the material is mostly anti-slip rubber or material with anti-slip texture, which enhances the friction with the ground and prevents the drone from slipping when taking off, landing or parking.

[0036] Specifically, such as Figure 5 As shown, a sliding groove 16 is provided at the top of the inner wall of the adjusting groove 404, and a sliding block 17 that cooperates with the sliding groove 16 is fixedly connected to the top of each of the two adjusting blocks 405.

[0037] Specifically, such as Figure 5 As shown, a sliding rod 18 is fixedly connected to the inner wall of the sliding groove 16, and two sliding blocks 17 are movably connected to the surface of the sliding rod 18.

[0038] In this embodiment: by setting a sliding groove 16 and a sliding block 17, the sliding block 17 is adjusted along the inner wall of the adjusting groove 404 with the adjusting block 405, avoiding the adjusting block 405 from rotating with the bidirectional threaded rod 403, ensuring that the adjusting block 405 moves only in a straight line. By setting a sliding rod 18, which is fixed to the inner wall of the sliding groove 16 and passes through the sliding block 17, the movement trajectory of the sliding block 17 is further limited, enhancing the stability of the sliding block 17 when it moves and preventing the sliding block 17 from deviating within the sliding groove 16.

[0039] Working principle: The entire landing gear is fixed to the bottom of the drone via mounting plate 1. When the spacing of the support frames 406 needs to be adjusted according to the landing position, the motor 402 on the right side of the hollow plate 401 in the adjustment assembly 4 is activated. The motor 402 drives the bidirectional threaded rod 403 to rotate. Since the surface of the bidirectional threaded rod 403 has reverse threads, the two adjusting blocks 405 connected by the threads on its surface will move closer or further away along the adjusting groove 404 at the bottom of the hollow plate 401. At the same time, the sliding block 17 at the top of the adjusting block 405 moves along the sliding rod 18 in the sliding groove 16, ensuring that the adjusting block 405 only makes linear movements, thereby driving the two support frames 406 at the bottom to adjust the spacing. When the support frame 406 moves, the extension rod 7 connected to its inner side will... The storage rod 6 extends and retracts synchronously. The auxiliary block 8 at the top of the extension rod 7 slides along the auxiliary groove 9 on the inner wall of the storage rod 6 to prevent the support frame 406 from shaking. The auxiliary frames 10 on both sides of the bolt plate 5 provide stable support for the storage rod 6. During take-off and landing, the spring 12 in the groove 11 at the bottom of the support frame 406 absorbs the impact force of the ground through elastic deformation. The adjustment plate 13 moves up and down in the groove 11 according to the flatness of the ground. Together with the base plate 14, it increases the ground contact area, and the anti-slip plate 15 enhances the friction, ensuring that the drone takes off, lands, and parks smoothly. If it is necessary to adjust the overall orientation of the landing gear, the servo motor 2 at the bottom of the mounting plate 1 is started. The servo motor 2 drives the adjustment disk 3 to rotate, thereby adjusting the orientation of the adjustment component 4 and the support frame 406 to adapt to different landing angles.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
