The first airbag 23 is arranged on both sides inside the cross frame 22. The support rod 24 is slidably connected in the cross frame 22 and supported on the surface of the first airbag 23. The support foot 25 is fixedly connected to the bottom of the support rod 24. A clamping assembly for clamping a rod-shaped object is arranged in the middle of the bottom end of the cross frame 22.

[0028] The main body 1 of the flapping-wing aircraft includes a frame 11 and wings 12 arranged on the main body 1 of the flapping-wing aircraft. A tail 13 is also arranged at the tail of the frame 11.

[0029] It should be noted that the main body 1 of the flapping-wing aircraft mainly includes a frame 11, wings 12 designed to imitate the shape of bird wings are installed on the frame 11, and a tail 13 located at the tail of the frame 11, which is used to improve the stability during flight. The frame 11 is made of a lightweight and high-strength material to ensure that the aircraft has sufficient strength while maintaining light weight.

[0030] The soft landing mechanism is located at the bottom of the flapping-wing aircraft body 1 and is used to reduce the impact force when the aircraft lands. The landing bracket 21 is fixedly connected to the bottom of the flapping-wing aircraft body 1 and serves as the support basis for the entire soft landing system. The cross frame 22 is fixed below the landing bracket 21 and is used as an installation platform for other internal components. The first airbag 23 is located on both sides inside the cross frame 22 and absorbs the impact energy during landing by inflating and deflating. The support rod 24 can slide inside the cross frame 22, with one end contacting the first airbag 23 and the other end connected to the support foot 25.

[0031] In an alternative embodiment: The support foot 25 includes a mounting shell and a support rubber strip. The support rubber strip is fixedly connected to the mounting shell, and the mounting shell is fixedly connected to the bottom of the support rod 24.

[0032] It should be noted that the support foot 25 includes a mounting shell and a support rubber strip, where the support rubber strip is fixed to the mounting shell, and the mounting shell is fixed to the lower end of the support rod 24 to directly contact the ground and provide additional cushioning.

[0033] In an alternative embodiment: The clamping assembly includes a two-way hydraulic rod 26, a sliding clamping plate 27, and a clamping member 28. The two-way hydraulic rod 26 is fixedly installed in the cross frame 22. The output ends of the two-way hydraulic rod 26 are fixedly connected to the sliding clamping plates 27, and the clamping member 28 is slidably connected to a groove at one end of the sliding clamping plate 27.

[0034] It should be noted that the two-way hydraulic rod 26 is fixed inside the cross frame 22, and its two ends are respectively connected to the sliding clamping plates 27. The position of the sliding clamping plates 27 is adjusted through hydraulic control. The sliding clamping plates 27 are connected to the two-way hydraulic rod 26 and can move under its drive. The clamping member 28 is slidably connected to a groove at one end of the sliding clamping plate 27 and is used to clamp the rod-shaped object to ensure that the aircraft can imitate a bird staying on an object such as a branch.

[0035] In an alternative embodiment: A second airbag 29 is arranged in the groove, and the clamping member 28 is supported at one end of the second airbag 29.

[0036] It should be noted that the second airbag 29 is located in the groove of the sliding clamping plate 27 to provide additional cushioning for the clamping member 28 and ensure the effect of soft landing.

[0037] In an alternative embodiment: Both sides at one end of the groove are fixedly connected with mounting springs 30, and the other ends of the mounting springs 30 are fixedly connected to both sides at one end of the clamping member 28.

[0038] It should be noted that the mounting spring 30 is fixed on both sides of one end of the groove, and the other end is connected to the clamping member 28. When the clamping member 28 is subjected to an external force, it can undergo elastic deformation, first achieving the effect of soft landing, and then performing clamping and fixing.

[0039] In an alternative embodiment: a clamping groove is provided on the clamping end face of the clamping member 28.

[0040] It should be noted that the clamping groove is provided on the clamping end face of the clamping member 28 to increase the friction force between the clamping member and the ground or other contact objects, ensuring that the aircraft can stay stably on the ground.

[0041] Among them, the frame 11 is made of a lightweight and high-strength material, ensuring that the aircraft has both sufficient strength and remains lightweight, improving the stability and safety during flight.

[0042] Working principle: The support rod 24 slides downward as the aircraft descends, squeezing the first airbag 23. The first airbag 23 absorbs part of the impact energy, reducing the impact on the aircraft body. The support rubber strip on the support foot 25 contacts the ground, providing further buffering. If the aircraft attempts to dock on an object such as a tree branch, the clamping assembly will act. The double-acting hydraulic rod 26 drives the sliding clamping plate 27 to move, causing the clamping member 28 to approach the rod-shaped object. The second airbag 29 and the mounting spring 30 on the clamping member 28 absorb the impact force during contact. Finally, the clamping groove on the clamping member 28 tightly grips the rod-shaped object to complete the docking action.

[0043] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
