The invention discloses an aircraft back support nacelle lip opening and closing structure and an aircraft. The aircraft back support nacelle lip opening and closing structure comprises two lip skin capable of being opened and closed, a supporting frame, a supporting partition plate, a lip opening and closing connecting rod mechanism and a locking mechanism. The lip skin comprises a first lip skin and a second lip skin; the supporting frame is fixedly arranged on the inner side of the first lip skin; the supporting partition plate is located between the first lip skin and the second lip skin and fixed to the upper surface of the wing. The lip opening and closing connecting rod mechanism is hinged to the supporting frame, and the supporting partition plate is hinged to the second lip skin. The lip opening and closing connecting rod mechanism comprises an elastic component, and the elastic component is located between the first lip skin and the second lip skin. The locking mechanism is in linkage fit with the first lip skin and the second lip skin. According to the lip opening and closing connecting rod mechanism, translation opening and closing of the lip are achieved through cooperation of the elastic component and the connecting rod, and a smoother opening and closing mode is provided for a back supporting type nacelle; the maintenance space of the wing surface can be further expanded through translation opening and closing, the maintenance efficiency can be improved when a nacelle and a lip are maintained, and the maintenance time is saved.

    本发明公开了一种飞机背撑短舱唇口开闭结构及飞机,包括:两个可开闭设置的唇口蒙皮、支撑框、支撑隔板、唇口开闭连杆机构和锁紧机构;唇口蒙皮包括第一唇口蒙皮和第二唇口蒙皮;支撑框固定设置在第一唇口蒙皮的内侧;支撑隔板位于第一唇口蒙皮和第二唇口蒙皮之间,且固定在机翼的上表面;唇口开闭连杆机构分别与支撑框铰接、支撑隔板和第二唇口蒙皮铰接;唇口开闭连杆机构包括弹性部件,弹性部件位于第一唇口蒙皮和第二唇口蒙皮之间;锁紧机构与第一唇口蒙皮和第二唇口蒙皮联动配合。本发明唇口开闭连杆机构的弹性部件和连杆的配合实现了唇口的平移开启和闭合,为背撑式短舱提供了更加顺畅的开闭方式;平移开闭可进一步扩大在机翼翼面维护的空间,在维护短舱、唇口时可以提升维护效率,节省维护时间。
