[0029] Example 1, such as Figure 1-4As shown, a drone landing gear and a drone are provided. The drone body 1 has wings 2 evenly arranged on its side. The drone body 1 has a landing gear 3 at its bottom and a fixing device 4 at its bottom. A protective device 5 is provided on one side of the landing gear 3. When using the drone, the wings 2 carry the drone body 1 into the air, and then the drone can be remotely controlled by remote control. This allows the drone to perform remote monitoring and other functions.

[0030] Reference Figure 2 and Figure 3 The fixing device 4 includes a fixing block 401, which is fixedly connected to the bottom of the UAV body 1. A fixing frame 403 is slidably fitted onto the surface of the fixing block 401. The bottom of the fixing frame 403 is fixedly connected to the top of the landing gear 3. A connecting groove 402 is formed on the surface of the fixing block 401. A connecting strip 404 is slidably connected to the inner wall of the connecting groove 402. The connecting strip 404 is fixedly connected to the inner wall of the fixing frame 403. When using the fixing device 4, the fixing frame 403 is manually slid to the bottom of the fixing block 401, and then the connecting strip 404 is slid into the connecting groove 402. The landing gear 3 is positioned inside the body of the UAV 1, making it easy to replace without tools. A limiting groove 406 is provided on one side of the fixing block 401. A limiting frame 407 is slidably connected to the inner wall of the limiting groove 406. A U-shaped plate 405 is fixedly connected to the bottom of the limiting frame 407. The U-shaped plate 405 is slidably fitted onto the bottom of the fixing block 401. The fixing block 401 is located on one side of the fixing frame 403. The U-shaped plate 405 can be manually slid onto the surface of the fixing block 401, thereby sliding the limiting frame 407 into the limiting groove 406. Internally, the connecting strip 404 is confined within the connecting groove 402 by the U-shaped plate 405. A locking groove 408 is provided on one side of the fixing block 401. A locking plate 409 is slidably connected to the inner wall of the locking groove 408. The locking plate 409 is slidably connected to the inner wall of the limiting frame 407. Sliding the locking plate 409 into the locking groove 408, and then into the limiting frame 407, facilitates confining the limiting frame 407 within the limiting groove 406. This, in turn, confines the U-shaped plate 405 to the surface of the fixing block 401. The locking groove 408... A first damping rod 410 is fixedly connected to one side of the wall. The end of the first damping rod 410 away from the locking groove 408 is fixedly connected to one side of the locking plate 409. A first spring 411 is sleeved on the surface of the first damping rod 410. One end of the first spring 411 is fixedly connected to one side of the inner wall of the locking groove 408. The end of the first spring 411 near the first damping rod 410 is fixedly connected to one side of the locking plate 409. The locking plate 409 is pulled towards the locking groove 408 by the first spring 411, thereby making it easier to restrict the locking plate 409 inside the locking groove 408.

[0031] Reference Figure 4The protective device 5 includes a support rod 507. A fixing strip 504 is fixedly connected to one side of the landing gear 3. A connecting frame 505 is fixedly connected to the side of the fixing strip 504 away from the landing gear 3. A round rod 506 is fixedly connected to the inner wall of the connecting frame 505. The support rod 507 rotates on the surface of the round rod 506. When the protective device 5 is used, if the drone is landing and tilted, the support rod 507 rotates on the surface of the round rod 506, thus supporting the drone and preventing it from tipping over to some extent. A limit strip 508 is fixedly connected to the side of the connecting frame 505 away from the fixing strip 504. The limit strip 508 prevents the support rod 507 from rotating too much and causing the drone to tip over. A third spring 5 is fixedly connected to one side of the fixing strip 504. 09. The end of the third spring 509 away from the fixing bar 504 is fixedly connected to the bottom of the support rod 507. The third spring 509 pulls the support rod 507 towards the fixing bar 504, which facilitates the placement of the support rod 507 on both sides of the landing gear 3. The bottom of the landing gear 3 is evenly fixedly connected to the second damping rod 501. The bottom of the second damping rod 501 is fixedly connected to the connecting plate 503. The surface of the second damping rod 501 is fitted with a second spring 502. The bottom of the second spring 502 is fixedly connected to the top of the connecting plate 503. The top of the second spring 502 is fixedly connected to the bottom of the landing gear 3. The second spring 502 presses the connecting plate 503 away from the bottom of the landing gear 3. This can provide a certain buffer when the landing gear 3 falls to the ground, which can prevent the main body of the UAV 1 from being hit.

[0032] Working principle: When using the drone, the wing 2 carries the drone body 1 into the air, and then the drone can be remotely controlled via remote control. This allows for remote monitoring and other functions. When using the fixing device 4, manually slide the fixing frame 403 to the bottom of the fixing block 401, then slide the connecting strip 404 into the inside of the connecting groove 402. Manually slide the U-shaped plate 405 onto the surface of the fixing block 401, then slide the limiting frame 407 into the inside of the limiting groove 406. Then slide the locking plate 409 into the inside of the locking groove 408. The first spring 411 pulls the locking plate 409 towards the locking groove 408, thus confining the locking plate 409 within the locking groove 408. Then, slide the locking plate 409 into the inside of the limiting frame 407, thus confining the limiting frame 407 within the limiting groove 406. The U-shaped plate 405 is constrained on the surface of the fixing block 401. This allows the connecting strip 404 to be confined inside the connecting groove 402, facilitating the placement of the landing gear 3 at the bottom of the drone body 1. This makes it easy to replace the landing gear 3 without the need for tools. When the protective device 5 is used, if the drone is landing and tilted, the support rod 507 rotates on the surface of the round rod 506. The third spring 509 pulls the support rod 507 towards the fixing strip 504, making it easier to place the support rod 507 on both sides of the landing gear 3. This allows the drone to be supported by the support rod 507, thus preventing it from tipping over to some extent. When the landing gear 3 falls to the ground, it provides a certain degree of cushioning, preventing the drone body 1 from being hit.

[0033] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
