[0023] Furthermore, it should be noted that the directional terms such as left, right, up, and down used in the embodiments of this utility model are only relative concepts or references to the normal use of the product, and should not be considered restrictive. The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Example 1:

[0025] As attached Figure 1 The image shows a shock-absorbing landing support structure for a shared drone airdrop container, as illustrated in this embodiment. It is installed on the cargo container 1 carried by the drone. Figure 2 Appendix Figure 3 As shown, the shock-absorbing landing support structure includes a mounting component 2, a base plate 3, a rotating shaft 11, a tension spring 4, and a torsion spring 5. The mounting component 2 is installed at the four corners of the bottom of the cargo box 1. The bottom of the mounting component 2 has a downwardly extending support rod 6. The end of the support rod 6 near the mounting component 2 has a first spring hole 61, and the end of the support rod 6 away from the mounting component 2 has a first shaft hole. The base plate 3 has supports 7 located on both sides of the support rod 6. The supports 7 have second shaft holes corresponding to the first shaft holes. The rotating shaft 11 passes through the first shaft hole and the second shaft hole to rotatably connect the support rod 6 and the base plate 3. (See attached diagram) Figure 4As shown, the torsion spring 5 includes a middle section 51 that abuts against the support rod 6 and a helical section 52 connected to both ends of the middle section 51 and sleeved on the rotating shaft 11. The outer side of the helical section 52 has a bent section 53 that abuts against the base plate 3. The symmetrical structure of the torsion spring 5 makes the force distribution of the shock-absorbing landing support structure more balanced. The inner side of the support rod 6 has a groove, and the middle section 51 of the torsion spring 5 is stuck in the groove to prevent it from slipping out during rotation and affecting the force distribution. The base plate 3 has a second spring hanging hole 31. In this embodiment, the second spring hanging hole 31 is formed by a protrusion stamped on the base plate 3. The two ends of the tension spring 4 are connected to the first spring hanging hole 61 and the second spring hanging hole 31, respectively. The torsion spring 5 causes the support rod 6 and the base plate 3 to be subjected to a force that opens them apart, while the tension spring 4 causes the support rod 6 and the base plate 3 to be subjected to a force that closes them together. The two are in balance, and can adjust and buffer internally when subjected to vibration, reducing the vibration of the cargo box 1, ensuring the safety and stability of the goods, reducing the pressure on the airdrop container to receive the cargo box 1, and making the docking of the airdrop container and the drone smoother.

[0026] Mounting component 2 includes a bottom wall 21 and two side walls 22 perpendicular to the bottom wall 21 and in contact with the adjacent surfaces of the cargo box 1. The bottom wall 21 has a carrier plate 8 in contact with the bottom surface of the cargo box 1. A compression spring 9 connects the bottom wall 21 and the carrier plate 8. When the cargo box 1 is subjected to vibration, the compression spring 9 absorbs a portion of the force, further improving the overall shock absorption capacity. The side walls 22 have through-holes 23 for strip-shaped objects to pass through. The shock-absorbing landing support structure can be installed at the four corners of the cargo box 1 using straps, making installation and disassembly convenient and facilitating reuse.

[0027] Example 2:

[0028] As attached Figure 5 The diagram shows a shock-absorbing landing support structure for a shared drone airdrop container according to this embodiment. It includes a mounting component 2, a base plate 3, a rotating shaft 11, a tension spring 4, and a torsion spring 5. The mounting component 2 is installed at the four corners of the bottom of the cargo box 1. The bottom of the mounting component 2 has a downwardly extending support rod 6. The end of the support rod 6 near the mounting component 2 has a first spring-hanging hole 61, and the end away from the mounting component 2 has a first shaft hole. The base plate 3 has supports 7 located on both sides of the support rod 6. The supports 7 have second shaft holes corresponding to the first shaft holes. The rotating shaft 11 passes through the first and second shaft holes, rotatably connecting the support rod 6 and the base plate 3. The torsion spring 5 includes a middle section 51 that abuts against the support rod 6 and a helical section 52 connected to both ends of the middle section 51 and sleeved on the rotating shaft 11. The outer side of the helical section 52 has a bent section 53 that abuts against the base plate 3. The base plate 3 has a second spring-hanging hole 31, and the two ends of the tension spring 4 are connected to the first spring-hanging hole 61 and the second spring-hanging hole 31, respectively.

[0029] The end of the support rod 6 furthest from the mounting part 2 is curved, with the axis of the first shaft hole as its center. The curved surface is tangent to the base plate 3, making the rotation of the support rod 6 relative to the base plate 3 more stable, reducing swaying, and providing stronger support when subjected to impact, thus preventing the shaft 11 from breaking due to stress alone. A shock-absorbing pad 10 is installed on the bottom surface of the base plate 3, which reduces vibration and wear, extending its service life.

[0030] Mounting component 2 has mounting holes 24, which facilitates nailing the mounting component to the cargo box 1 with screws. This is commonly used when the cargo box 1 is a wooden box. In contrast, embodiment 2 is more suitable for cases where the cargo box 1 is heavier and a more secure and stable connection of mounting component 2 is required. Embodiment 1 is suitable for cases where the cargo box 1 is slightly lighter and quick assembly and disassembly are required. By adjusting the parameters between the spring and the tension spring according to the load conditions, it has a wider range of applicability.

[0031] This utility model provides a shock-absorbing landing support structure for a shared drone delivery locker, which effectively cushions the delivery end of the drone, ensuring that the goods arrive at their destination intact, reducing damage to the goods, lowering the receiving pressure on the delivery locker, and increasing users' trust in drone delivery.
