The operator takes out the buffer structure and the fastening screw 12, and threadedly connects the fastening screw 12 through the mounting frame 8 and the threaded seat 10. This allows it to be installed. When the UAV body 1 starts up and needs to descend, the bottom buffer plate 30, rubber plate 16, and rubber pad 17 contact the ground first, while the support frame 27 and the shock-absorbing pad 29 contact the plane. Then the telescopic rod 14 moves into the telescopic sleeve. The return spring 23 is installed, and the high elasticity material ensures that the stamping can achieve precise return. Therefore, the buffer structure has a strong buffering effect when in use.

[0028] A slot 19 is provided at the bottom of the buffer plate 30, and a slot 21 is provided inside the slot 19. Since there is a slot 19 and a slot 21, it is convenient to insert the card block 20 into the slot 21 and insert the insert plate 18 into the slot 19.

[0029] The rubber plate 16 is provided with an insert plate 18 on the outside, and a locking block 20 is provided on the outside of the insert plate 18. The insert plate 18 is embedded in the slot 19, and the locking block 20 is embedded in the slot 21. Because of the insert plate 18 and the slot 19, it is convenient to install the rubber plate 16 and the rubber pad 17 at the bottom of the buffer plate 30.

[0030] The bottom of the outer ring body 6 is provided with support rods 26, which are symmetrically distributed. The bottom of the support rods 26 is provided with support frame 27. The support rods 26 facilitate the installation of support frame 27 at the bottom of the outer ring body 6.

[0031] The bottom of the support frame 27 is provided with a rubber block 28, and the other side of the rubber block 28 is provided with a shock-absorbing pad 29.

[0032] The mounting bracket 8 has a through hole 11 inside, and a fastening screw 12 is embedded inside the through hole 11. Because of the through hole 11, it is convenient for the fastening screw 12 to pass through the interior of the mounting bracket 8 and be threadedly connected to the threaded seat 10 on the outside of the top plate 9.

[0033] The working principle of this large-capacity drone with a landing buffer structure is as follows: When using this device, a support frame 2 is first installed at the bottom of the drone body 1. An inner ring 4 is installed on the outside of the support frame 2, and a connecting plate 5 is installed on the outside of the inner ring 4. A load-bearing frame 3 is installed on the top of the connecting plate 5 with the help of straps to support the load. An outer ring 6 is installed on the outside of the inner ring 4, and a support frame 27 is connected to the outside of the outer ring 6 by a support rod 26. The bottom of the support frame 27 is connected to the shock-absorbing foot pad 29 by a rubber block 28. However, in order to raise the bottom of the drone body 1... The buffering effect is achieved by installing a threaded seat 10 and a fastening screw 12 on the side of the top plate 9, and by providing a telescopic rod 14 and a fixing sleeve 15 on the side of the top plate 9. The outer side of the top plate 9 is connected to a return spring 23 through a first tube, and a rubber column 22 is installed inside the return spring 23. The other side of the rubber column 22 is connected to a buffer plate 30 through a second block 25. A rubber plate 16 and a rubber pad 17 are installed at the bottom of the buffer plate 30. Before using the UAV body 1, the operator removes the buffer structure and the fastening screw 12, and then initially inserts the fastening screw 12 through the mounting frame 8. The internal perforation 11 is then tightened, and the fastening screw 12 is screwed into the threaded seat 10 for threaded connection, thus enabling installation. Next, the rubber plate 16 and rubber pad 17 are removed again. The insert plate 18 on the side of the rubber plate 16 is then inserted into the slot 19, and the locking block 20 is inserted into the slot 21, which serves to limit and fix the position. The items to be transported are then placed into the load-bearing frame 3. After that, the drone body 1 is restarted for transportation. When the drone body 1 reaches the designated position and descends, the buffer plate 30, rubber plate 16, and rubber pad at its bottom will engage. 17 is the first to contact the ground, while the support frame 27 and the shock-absorbing pad 29 contact the plane. After the rubber pad 17 contacts the ground, the telescopic rod 14 on the side of its top plate 9 moves into the telescopic sleeve. Moreover, a return spring 23 is installed on the outside of the rubber column 22, which can quickly return to its original position after being subjected to pressure. Therefore, the buffer structure has a strong buffering effect during use. Finally, when the rubber plate 16 and the rubber pad 17 are severely deformed after long-term use, the staff can disassemble the rubber plate 16 and replace it with a new rubber plate 16 and rubber pad 17.
