| description | The invention provides an aircraft cabin door lifting assisting mechanism, belongs to the field of civil aircraft cabin door mechanisms, and particularly relates to a cabin door lifting assisting mechanism which is applied to a civil aircraft cabin door and can provide staged precise assisting force in a certain stage in the cabin door lifting process. The cabin door structure is fixedly connected with a power-assisted roller, the rocker arm is hinged to the cabin door structure, the rocker arm is fixedly connected with a transmission roller, the fork-shaped piece is hinged to the fuselage door frame structure, the fork-shaped piece is provided with a sliding groove and a power-assisted arm, and the lower portion of the fork-shaped piece is connected with a spring assembly. After the fork-shaped piece rotates by a certain angle, the assisting arm makes contact with the assisting roller, and the spring force of the spring assembly provides assisting force for lifting the cabin door.
