Airplane cabin door connecting rod mechanism integrated with safety spring function
The invention provides an aircraft cabin door connecting rod mechanism integrated with a safety spring function, and belongs to the field of civil aircraft cabin door mechanisms. The device comprises a driven crank, an elastic connecting rod, a driving crank, a compression spring and a limiting pin, the driven crank and the driving crank are connected through the elastic connecting rod and then hinged to a cabin door structure, the limiting pin is arranged above the driven crank for limiting, the elastic connecting rod is of a telescopic connecting rod structure formed by sleeving an upper guide rod and a lower guide rod, and the upper guide rod is provided with a long round hole; a stop pin is arranged in the hole and movably connected with the lower guide rod, and a compression spring is installed between the upper guide rod and the lower guide rod to press the elastic connecting rod in the longest state. A safety spring mechanism of the cabin door is integrated into a transmission four-bar mechanism of the cabin door, the number of the mechanisms is reduced, the weight of the cabin door is reduced, the basic reliability of the mechanisms is improved, the space requirement for mechanism layout is lowered, the design difficulty is lowered, the structural part form is simple, and the cabin door mechanism can be widely applied and popularized to design of various types of cabin door mechanisms.
本发明提供了一种集成安全弹簧功能的飞机舱门连杆机构，属于民机舱门机构领域。本发明包括从动曲柄、弹性连杆、主动曲柄、压缩弹簧、限位销，从动曲柄和主动曲柄通过弹性连杆连接后与舱门结构铰接，从动曲柄上方布置限位销限位，弹性连杆由上、下导杆套合形成可伸缩的连杆结构，上导杆制长圆孔，孔内设止动销与下导杆可运动连接，上、下导杆之间安装压缩弹簧，将弹性连杆压紧在长度最长状态。本发明将舱门的安全弹簧机构集成到了舱门的传动四杆机构中，减少了机构数量，降低了舱门重量，提高了机构的基本可靠性，降低机构布局的空间要求，降低设计难度，结构件形式简单，可以广泛推广应用到各种类型的舱门机构设计中。
