The invention discloses a cabin door folding and unfolding device for an undercarriage of an aircraft. The aircraft comprises the undercarriage rotatably mounted in a cabin body of the aircraft and two oppositely arranged cabin doors suitable for closing the cabin body when the undercarriage is folded. The cabin door folding and unfolding device of the undercarriage comprises two folding and unfolding mechanisms which are matched with cabin doors respectively, each folding and unfolding mechanism comprises a connecting part, and the first end of each connecting part is rotatably connected with the undercarriage; the base is mounted in the cabin body; the transmission part is mounted on the base, and the second end of the connecting part is rotatably mounted to the transmission part; the first end of the hinge part is connected with the transmission part, the second end of the hinge part is connected with the cabin door, and rotation of the undercarriage in the longitudinal vertical plane drives the hinge part to rotate in the transverse vertical plane relative to the base through the connecting part and the transmission part; the cabin door is switched between an opening state for opening the cabin body and a closing state for closing the undercarriage in the cabin body.

    本发明公开了一种用于飞行器的起落架的舱门收放装置,飞行器包括可转动地安装在飞行器的舱体内的起落架、以及适用于在起落架收起时关闭舱体的两个面对设置的舱门;起落架的舱门收放装置包括两个分别与舱门配合的收放机构,每个收放机构包括:连接部,连接部的第一端与起落架可转动地连接;基座,安装在舱体内部;传动部,安装在基座上,连接部的第二端可转动地安装至传动部;以及铰链部,铰链部的第一端与传动部连接,铰链部的第二端与舱门连接,起落架在纵向竖直面内的转动通过连接部和传动部驱动铰链部相对于基座在横向竖直平面内旋转,使得舱门在打开舱体的打开状态和将起落架封闭在舱体内的关闭状态之间转换。
