Opening and closing mechanism of electric outward opening type cabin door and aircraft
The invention provides an opening and closing mechanism of an electric outward-opening type cabin door and an aircraft, and belongs to the technical field of aircraft cabin doors. Supports in the opening and closing mechanism of the electric outward-opening type cabin door are fixed to the two sides of a lintel of a door frame structure; concave areas are formed in the two sides of the upper portion of the cabin door, electric rotating actuators and driving supporting arms are arranged in the concave areas, the electric rotating actuators are fixedly connected with torsion shafts, the torsion shafts are fixedly connected with power driving devices, and the power driving devices can drive the torsion shafts and the electric rotating actuators to rotate synchronously; each driving support arm is fixedly connected with a rotating shaft of the electric rotating actuator, and when the electric rotating actuator rotates, the driving support arms can be driven to rotate synchronously; the support double-lug is connected with a fork lug structure at the lower part of the driving support arm through the driven support arm; pollution caused by leakage of a hydraulic system is avoided; the structure is simple, layout is compact, and cargo space is not occupied; the weight is light, operation, installation and maintenance are convenient, and economical efficiency is good; the reliability is high.
本发明提供一种电动外开式舱门的打开关闭机构及飞行器，属于飞机舱门技术领域，该电动外开式舱门的打开关闭机构中支座固定在门框结构的门楣两侧；舱门上部两侧开设有凹陷区域，凹陷区域设有电动旋转作动器和驱动支臂，电动旋转作动器与扭力轴固连，扭力轴与动力驱动装置固连，动力驱动装置能带动扭力轴和电动旋转作动器同步转动；每个驱动支臂与电动旋转作动器的转轴固连，电动旋转作动器转动时，能带动驱动支臂同步转动；支座双耳通过从动支臂与驱动支臂下部叉耳结构连接；本发明避免了液压系统泄漏造成的污染；结构简单，布局紧凑，不占用货舱空间；重量轻，操作和安装维护方便，经济性好；可靠性高。
