The invention provides a connecting rod mechanism and an undercarriage and an aircraft comprising the connecting rod mechanism, the connecting rod mechanism has an extension state and a contraction state, and the connecting rod mechanism comprises a base, a first connecting rod, a second connecting rod, a third connecting rod, a driving shaft and a locking device. The base is fixedly mounted; the first connecting rod is rotationally connected with a first position of the base; a first limiting structure used for limiting in the stretching state is arranged between the first connecting rod and the base. The second connecting rod is rotationally connected with the first connecting rod; the third connecting rod is rotationally connected with the second connecting rod and the second position of the base; a second limiting structure used for limiting in the stretching state is arranged between the third connecting rod and the second connecting rod. The driving shaft is driven by the power assembly to rotate bidirectionally so as to drive the connecting rod mechanism to be switched between the stretching state and the contracting state. The locking device is driven by the driving shaft so as to lock the connecting rod mechanism in the contraction state and unlock the connecting rod mechanism in the state except the contraction state.
本发明提供一种连杆机构和包含该连杆机构的起落架、飞行器,该连杆机构具有伸展状态和收缩状态,该连杆机构包括:底座、第一连杆、第二连杆、第三连杆、驱动轴和锁止器。底座固定安装;第一连杆与底座的第一位置转动连接;第一连杆与底座之间设置有用于在伸展状态限位的第一限位结构;第二连杆与第一连杆转动连接;第三连杆分别与第二连杆和底座的第二位置转动连接;第三连杆与第二连杆之间设置有用于在伸展状态限位的第二限位结构;驱动轴在动力组件的驱动下双向转动以驱动连杆机构在伸展状态和收缩状态之间转换;锁止器受驱动轴驱动,以在收缩状态时,将连杆机构锁定,并在收缩状态以外的状态时将连杆机构解锁。
