[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] See also Figure 1-3The utility model provides a technical solution: a fixed-wing UAV lifting buffer component, including a mounting seat 1, a rotating shaft 8 and a connecting column 5. Fixed seats 2 are arranged on both sides of the bottom end of the mounting seat 1. The bottom of the fixed seat 2 is rotatably connected with a connecting column 3. The connecting column 3 is provided with empty grooves distributed along its length direction. The two ends of the rotating shaft 8 can be movably passed through the empty grooves. The connecting column 5 is fixedly connected to the bottom of the surface of the rotating shaft 8 and extends downwardly at an angle. The bottom of the mounting seat 1 is fixedly connected with a buffer component. The bottom end of the buffer component is provided with a semi-cylindrical support sleeve 9 nested in the surface of the rotating shaft 8. A damping buffer 7 is hinged between the surface of the connecting column 3 and the surface close to the connecting column 5.

[0019] In this embodiment, when descending, the connecting column 3 and the connecting column 5 are folded against each other after being subjected to force, and at the same time, the damping buffers 7 on their adjacent surfaces are subjected to force to reduce impact and vibration. At the same time, the rotating shaft 8 in the hollow grooves of the two connecting columns 3 slides upward, so that the buffer assembly is subjected to force at the same time to buffer the impact and vibration generated when subjected to external force.

[0020] The cushioning of fixed-wing drone landing is very important for protecting the drone, improving stability, protecting equipment, extending service life and improving safety. This can ensure that the impact of the drone during landing is minimized, improving the reliability and performance of the entire system.

[0021] Furthermore, the buffer assembly includes a spring 10 and a shock absorber 11 , one end of the spring 10 and the shock absorber 11 is fixedly connected to the top of the rotating shaft 8 , and the other end of the spring 10 and the shock absorber 11 is fixedly connected to the bottom of the mounting seat 1 .

[0022] In this embodiment, the spring 10 and the shock absorber 11 can buffer the impact and vibration generated when subjected to external forces, help reduce damage to equipment and structures, and provide smoother movement, which can protect equipment and structures from damage or fatigue. They can extend the service life of equipment, reduce the cost of maintenance and replacement, and reduce the spread of noise and vibration. They can reduce the vibration amplitude of the structure or equipment, thereby reducing the generation and spread of noise.

[0023] Furthermore, a support sleeve 9 is fixedly connected to the outer surface of the rotating shaft 8, and the support sleeve 9 is slidably connected to the inner cavity of the hollow groove.

[0024] In this embodiment, one end of the connecting column 5 rotates on the supporting sleeve 9, so that the connecting column 5 can be better stressed when descending.

[0025] Furthermore, a connecting seat 4 is fixedly connected to the top surface of the connecting column 3 , and a mounting plate 6 is fixedly connected to the bottom surface of the connecting column 5 .

[0026] In this embodiment, one end of the damping buffer 7 is hinged on the connecting seat 4, and the other end is hinged on the mounting plate 6, so that the damping buffer 7 is more stable and has better fastening performance.

[0027] Furthermore, a connecting block 12 is fixedly connected to the bottom end of the connecting column 5 , and a roller 13 is provided at the bottom end of the connecting block 12 .

[0028] In this embodiment, the roller 13 can make the drone move easily when landing, reduce the friction between the drone and the ground, and make the descent smoother.

[0029] Furthermore, a plurality of threaded holes are provided on the surface of the mounting base 1 , and the mounting base 1 is detachably mounted on the fixed-wing UAV via a plurality of bolts 14 .

[0030] In this embodiment, fixing the mounting base 1 to the drone by bolts 14 can provide a high-strength connection, so that the connected objects can withstand greater tension, pressure or shear force. They can ensure a firm connection between components and improve the stability and safety of the structure.

[0031] The working principle and use process of the utility model are as follows: after the utility model is installed, when the device is used, the mounting seat 1 is first fixed to the bottom of the fixed-wing UAV by bolts 14, and then when descending, the roller 13 first contacts the bottom surface, and the roller 13 first slides with the ground, and at the same time, under the action of the descending force, it is first folded through the connecting column 3 and the connecting column 5, and then the damping buffer hinged between the surface of the connecting column 3 and the surface close to the connecting column 5 first performs buffering to play the role of shock absorption and deceleration, and the rotating shaft 8 in the hollow groove of the two connecting columns 3 slides upward, so that the buffer component is simultaneously subjected to force to buffer the impact and vibration generated when it is subjected to external force, and then the buffer component at the bottom of the mounting seat performs secondary shock absorption and buffering, so that the impact force when the UAV collides with the ground or other objects reduces the risk to the surrounding personnel and environment, and then slowly and steadily lands. The device can improve the safety of the UAV landing, reduce the impact and vibration of the UAV during landing, and prolong the service life of the UAV. The double buffer device helps to reduce the wear and fatigue of mechanical parts and prolong the sustainable use time of the UAV.
