Lifting power-assisted mechanism for cabin door of airplane
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. The power assisting device has the advantages of segmented precise power assisting, small occupied space, high power assisting efficiency and the like, and stable control over handle force in the cabin door lifting process can be achieved.
本发明提供一种飞机舱门提升助力机构,属于民机舱门机构领域,具体为一种应用于民用飞机舱门上,可以在舱门提升过程中某一阶段提供阶段性精准助力的舱门提升助力机构。舱门结构上固定连接有助力滚轮,摇臂与舱门结构铰接连接,摇臂上固定连接有传动滚轮,叉形件与机身门框结构铰链连接,叉形件上设计有滑槽和助力臂,下方连接有弹簧组件,摇臂转动后带动传动滚轮进入滑槽内部并驱动叉形件转动,叉形件转动一定角度后,助力臂与助力滚轮接触,弹簧组件的弹簧力为舱门提升提供助力。本发明具有可以分段精准助力、占用空间小、助力效率高等优点,可以实现舱门提升过程中手柄力的平稳控制。
