The retractable nose landing gear comprises an actuator and a shock absorber, the telescopic end of the shock absorber is connected with a tire, the actuator is rotationally connected with a fuselage, and the output end of the actuator is in transmission connection with the shock absorber through a retractable connecting rod and can drive the shock absorber to rotate relative to the fuselage. The shock absorber comprises an outer cylinder and an inner cylinder capable of sliding and rotating relative to the outer cylinder. According to the shock absorber, the normally-open hole and the one-way through hole are formed in the horizontal section of the inner cylinder, it is guaranteed that forward damping and reverse damping of the shock absorber are achieved through the structure, and the landing buffering function and the sliding damping function are both considered.

    本发明公开了一种无人机可收放前起落架及无人机,包括作动器、减震器,减震器的伸缩端连接有轮胎,作动器与机身转动连接,作动器的输出端通过收放连杆与减震器传动连接,并能够驱动减震器相对机身转动,减震器包括外筒及能够相对外筒滑动和转动的内筒。本发明中,通过在内筒的水平段上开设常开孔和单向导通孔,通过这一结构保证减震器的正向阻尼和反向阻尼实现,兼顾着陆缓冲与滑行减振功能。
