The invention discloses a helicopter undercarriage with the protection function; the undercarriage comprises a skid and an arch-shaped beam, the arch-shaped beam is connected to the top wall of the skid, a first supporting rod and a second supporting rod are connected to the inner wall of the arch-shaped beam, and a first supporting plate is rotatably connected to the outer wall of the first supporting rod; a first shock absorber body is connected to the top wall of the first supporting plate, a sleeve is connected to the bottom wall of the first supporting plate, a buffer shock absorption mechanism is arranged in the sleeve, the output end of the buffer shock absorption mechanism penetrates through the sleeve and is connected with a rotating shaft, a machine wheel is connected to the outer wall of the rotating shaft, and a connecting base is connected to the top wall of the arched beam. A supporting beam is connected to the inner wall of the connecting base, and a second buffer damping mechanism is connected to the top wall of the supporting beam; according to the helicopter undercarriage, a good buffering and damping effect can be effectively achieved on the helicopter body during landing, the situation that the helicopter is damaged due to the fact that the helicopter is subjected to high impact force during landing is avoided, and then a good protection effect is effectively achieved on the helicopter body.

    本发明公开了一种带有防护功能的直升机起落架,包括滑撬和弓形梁,弓形梁连接在滑撬顶壁上,弓形梁内壁上分别连接有第一支撑杆和第二支撑杆,第一支撑杆外壁上转动连接有第一支撑板,第一支撑板顶壁上连接有连接有第一减震器本体,第一支撑板底壁上连接有套筒,套筒内部设置有缓冲减震机构,缓冲减震机构输出端穿过套筒并连接有转动轴,转动轴外壁上连接有机轮,弓形梁顶壁上连接有连接座,连接座内壁上连接有支撑梁,支撑梁顶壁上连接有第二缓冲减震机构;本发明能够有效的对直升机本体在降落时起到良好的缓冲减震效果,避免直升机在降落时受到较强的冲击力,而发生损坏的情况,进而有效的对直升机本体起到良好的保护效果。
