[0027] ​​​The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example:

[0030] Reference Figures 1-7 A fixed-wing drone lifting and buffer assembly includes a fixed base 1 and a connecting base 10. A mounting plate 2 is fixedly connected to the bottom of the fixed base 1, and a movable wheel 3 is rotatably connected to the mounting plate 2 for supporting the fixed-wing drone. The movable wheel 3 can make the fixed-wing drone slide smoothly.

[0031] A connection hole is provided on the connector 10 for connecting the machine body.

[0032] A support rod 4 is also installed on the fixed base 1. A support plate 5 is fixedly connected to the support rod 4. A movable rod 11 is installed on the support plate 5. A piston 12 is fixedly connected to the movable rod 11. A damping hole 13 is opened on the piston 12. A damping plate 14 is provided on the top of the piston 12. The damping hole 13 is located below the damping plate 14. A buffer cylinder 8 is fixedly installed at the bottom of the connecting base 10. The buffer cylinder 8 can be filled with damping oil. The movable rod 11 can drive the piston 12 to move against the inner wall of the buffer cylinder 8, so that the damping oil can form a damping effect through the damping hole 13. Two sets of buffer cylinders 8 are symmetrically arranged.

[0033] When the drone lands and is subjected to impact, the fixed base 1 is firmly anchored to the bottom of the drone. The support rod 4 and the support plate 5 jointly support the movable rod 11. Under the influence of the ground impact, the movable rod 11 moves downward accordingly, causing the piston 12 to move on the inner wall of the buffer cylinder 8. During the movement of the piston 12, the damping oil flows through the damping hole 13, forming a liquid damping effect. The movement of the piston 12 also causes the damping oil to generate flow resistance within the buffer cylinder 8, further reducing the transmission of impact force. Furthermore, the setting of the damping plate 14 makes the flow path of the damping oil more complex, further enhancing the damping effect by increasing the flow resistance, ensuring the stability of the drone during takeoff and landing. The damping plate 14 is made of rubber or silicone to improve its service life.

[0034] In addition, with reference to Figure 6 and Figure 7 , the damping effect of the damping hole 13 shown in the figure is moderate, the hole at both ends is larger, but the hole in the middle is smaller. Figure 4

[0035] When the top of the damping hole 13 is small, the flow resistance increases, the speed of the damping oil through the hole slows down, and the damping effect is hard (as shown in Figure 6 When the diameter of the damping hole 13 is larger, the flow resistance of the damping oil decreases, the speed of the oil through the hole increases, and the damping effect is soft (as shown in Figure 7 According to actual needs, the size of the damping hole 13 can be adjusted and the damping oil with appropriate viscosity can be selected to dynamically adjust the softness and hardness of the damping, which makes the fixed-wing unmanned aerial vehicle maintain the best performance under different working conditions and improves the lifting stability of the fixed-wing unmanned aerial vehicle.

[0036] The support rod 4 is fixedly connected to the top of the fixed seat 1, the support disc 5 is fixedly connected to the support rod 4, the sealing cover 9 is threadedly connected to the damping cylinder 8, the damping spring 6 is sleeved on the damping cylinder 8, and the two ends of the damping spring 6 are respectively abutted against the sealing cover 9 and the support disc 5. The damping spring 6 has a certain elasticity, and the two ends of the damping spring 6 are respectively abutted against the sealing cover 9 and the support disc 5. The damping spring 6 provides additional damping effect, and when the damping spring 6 is compressed, it can absorb and buffer most of the impact energy to reduce the impact during landing.

[0037] The damping air bag 7 is sleeved on the movable rod 11, the two ends of the damping air bag 7 are respectively abutted against the damping cylinder 8 and the support disc 5, and the damping air bag 7 is in the shape of a cylinder and has a through hole formed in the middle portion, and the inner wall of the through hole is abutted against the movable rod 11.

[0038] The damping air bag 7 is in the shape of a cylinder and has a through hole formed in the middle portion, the two ends of the damping air bag 7 are respectively abutted against the damping cylinder 8 and the support disc 5, and the inner wall of the damping air bag 7 is abutted against the movable rod 11. When the fixed-wing unmanned aerial vehicle takes off or lands, the damping air bag 7 absorbs and buffers external impact by compression and release of the contained gas, thereby reducing the impact of the ground impact on the unmanned aerial vehicle and preventing strong impact, preventing damage to the data storage device on the fixed-wing unmanned aerial vehicle, thereby protecting data information and improving the protection effect.
