The invention discloses an unmanned aerial vehicle with vibration reduction undercarriages. The unmanned aerial vehicle comprises a vehicle body; vehicle arms which are connected with the vehicle body; rotor wing assemblies which are arranged at the ends, away from the fuselage, of the vehicle arms; an undercarriage which comprises a first pipe fitting and a second pipe fitting, the two axial endsof the first pipe fitting are connected with the second pipe fitting respectively, the second pipe fitting is located above the first pipe fitting, a connecting plate is rotationally installed at theend, away from the first pipe fitting, of the second pipe fitting, the connecting plate is detachably connected with the fuselage, and external threads are arranged on the peripheral wall of the first pipe fitting; sleeves, wherein the first pipe fitting is sleeved with a plurality of spaced sleeves, internal threads are arranged on the inner circumferential walls of the sleeves, and the internalthreads are in threaded fit with the external threads; and a flexible part which is configured to be annular and extend in the axial direction of the sleeve, and the sleeve is detachably sleeved withthe flexible part. The device can adjust the position of the sleeve by rotating the sleeve so as to adjust an abrasion surface and the abrasion position of the flexible part so that the service lifeis prolonged.
本发明公开了一种具有减振起落架的无人机,包括:机身;机臂,机臂与机身相连;旋翼组件,旋翼组件设于机臂的远离机身的一端;起落架,起落架包括第一管件和第二管件,第一管件的轴向两端分别与第二管件相连,第二管件位于第一管件上方,第二管件的远离第一管件的一端转动安装有连接板,连接板与机身可拆卸相连,第一管件的外周壁上设有外螺纹;套筒,第一管件上外套有多个间隔开的套筒,套筒的内周壁上设有内螺纹,内螺纹与外螺纹螺纹配合;和柔性件,柔性件被构造成呈环形且沿套筒的轴向方向延伸,柔性件可拆卸地外套在套筒上。本装置可通过转动套筒,调整套筒的位置进而调整柔性件的磨损面和磨损位置,以延长使用寿命。
