The invention belongs to the technical field of airplane cabin door structural design, and particularly relates to a large cabin door motion state indicating device. Comprising a connecting shaft, a first cam, a second cam and a pull rod are arranged on the connecting shaft, and the pull rod is connected with a cabin door; the terminal switch module for indicating the opening state of the cabin door comprises a first terminal switch, a first switch pressing block mechanism and a first support. The terminal switch module for indicating the closed state of the cabin door comprises a second terminal switch, a second switch pressing block mechanism, a second reset spring and a second support. According to the large cabin door motion state indicating device, one set of mechanism and two electric switches are used, three kinds of electric signal combinations are output, and accurate indication of the cabin door motion state and coordinated linkage with other cabin doors can be achieved; compensation measures are adopted in the design, and the problem that structure deformation and vibration in airflow moving at a high speed easily cause false indication of the electric switch is solved.

    本申请属于飞机舱门结构设计技术领域,特别涉及一种大型舱门运动状态指示装置。包括:所述凸轮操控模块包括连接轴,所述连接轴上设置有第一凸轮、第二凸轮以及拉杆,所述拉杆与舱门连接;所述指示舱门开启状态的终点电门模块包括第一终点电门、第一电门压块机构以及第一支架;所述指示舱门关闭状态的终点电门模块包括第二终点电门、第二电门压块机构、第二复位弹簧以及第二支架;本申请的大型舱门运动状态指示装置,使用1套机构,2个电门,输出3种电信号组合,能够实现对舱门运动状态的准确指示及与其他舱门的协调联动;设计中采取了补偿措施,解决了高速运动的气流中结构变形及振动易引起电门误指示的难题。
