[0027] Reference Figure 1 As shown, the utility model provides a technical solution: a UAV landing gear that can adapt to different ground surfaces, including a body 1, and two landing gear bodies 2 are fixedly connected to the side walls of the body 1.

[0028] The following is a detailed description of its overall specific settings and functions.

[0029] Reference Figure 1-Figure 4 As shown, in this embodiment: the side wall of the landing gear body 2 is fixedly connected with two fixing cylinders 3, the side wall of the fixing cylinder 3 is rotatably connected with a support frame 4, and the side wall of the support frame 4 is fixedly connected with a cone rod 5. When the UAV is landing, the cone rod 5 will be inserted into the ground, thereby improving the stability of the body 1 on the ground and preventing the body 1 from tipping over.

[0030] The side wall of the support frame 4 is evenly provided with a plurality of slots 9, the upper side of the fixed cylinder 3 is fixedly connected with a fixed block 7, and the inside of the fixed block 7 is slidably connected with an insert 6, and the size of the insert 6 matches the size of the slot 9. The insert 6 is inserted into the inner wall of the slot 9, and the position of the support frame 4 after rotation can be fixed. The first spring 8 is fixedly connected to the side where the insert 6 and the fixed block 7 are close to each other. The insert 6 is inserted into the inner wall of the slot 9 under the pulling force of the first spring 8 on the fixed block 7.

[0031] Two slide bars 10 are slidably connected inside the support frame 4. A protective ring 11 is fixedly connected to one end of the two slide bars 10 close to each other. The protective ring 11 is located on the outside of the cone rod 5. The sliding protective ring 11 covers the tip of the cone rod 5, thereby covering the tip of the cone rod 5. A circular block 12 is fixedly connected to the other end of the slide bar 10. A second spring 13 is sleeved on the surface of the slide bar 10. The two ends of the second spring 13 are fixedly connected to the support frame 4 and the circular block 12 respectively. The second spring 13 plays a role in buffering the machine body 1 in this process, further improving the safety and stability of the machine body 1 when it lands.

[0032] Specifically, the support frame 4 is slidably connected to the inside with an insert frame 14, and the side wall of the circular block 12 is provided with a rectangular hole, and the size of the insert frame 14 matches the size of the rectangular hole. The insert frame 14 is slidably inserted into the inner wall of the rectangular hole, so as to further stabilize the position of the protective ring 11 covering the cone head. The side wall of the insert frame 14 is glued with an elastic strip 15, and the elastic strip 15 is slidably connected to the inside of the support frame 4. The setting of the elastic strip 15 increases the resistance in the process of moving the insert frame 14, and avoids the shaking of the insert frame 14 inside the support frame 4.

[0033] Working principle: when the body 1 is used on some muddy ground, first pull the insertion strip 6, rotate the support frame 4 on the side wall of the fixed cylinder 3, and point the tapered rod 5 on the support frame 4 toward the ground. After the support frame 4 is rotated to a suitable angle, loosen the insertion strip 6, and the insertion strip 6 will be inserted into the inner wall of the slot 9 by the pulling force of the first spring 8 on the fixed block 7. At this time, the position of the support frame 4 after rotation can be fixed. During the landing of the drone, the tapered rod 5 will be inserted into the ground, thereby improving the stability of the body 1 when it lands and avoiding the body 1 from tipping over. At this time, the protective ring 11 will be lifted up by the gravity when the body 1 lands. The second spring 13 plays a role of buffering the body 1 in this process, further improving the safety and stability of the body 1 when it lands. After the tapered rod 5 is pulled out from the ground, the sliding rod 10 will be driven by the elastic force of the second spring 13 between the support frame 4 and the circular block 12 to drive the protective ring 11 to cover The cover is placed at the tip of the cone rod 5, thereby covering the tip of the cone rod 5. The sliding insertion frame 14 is inserted into the inner wall of the rectangular hole, which can further stabilize the position of the protective ring 11 covering the rear of the cone head. By covering the tip of the cone rod 5, the safety of the machine body 1 during carrying is improved. The setting of the elastic strip 15 increases the resistance during the moving insertion frame 14 and avoids the shaking of the insertion frame 14 inside the support frame 4. The support frame 4 is folded to a position parallel to the bottom of the landing gear, and the machine body 1 can be used on some horizontal cement floors, thereby increasing the scope of use of the landing gear body 2 of the machine body 1. By setting the above structure, the flexible rotation of the support frame 4 on the side of the cone head facilitates the stable landing of the machine body 1 on different grounds, and the bottom structure of the landing gear body 2 can be adjusted according to the terrain, thereby improving the use effect of the landing gear body 2 to a certain extent.
