The invention provides an aircraft airfoil folding and unfolding mechanism which comprises a base, an actuator cylinder, a sliding block and a rotating frame, the actuator cylinder is installed on thebase, and the output end of the actuator cylinder is connected with the middle of the sliding block; rotating frames are hinged to the two ends of the sliding block; the rotating frames are fixedly connected with aircraft wing surfaces and are hinged to the base; hinged shafts of the sliding block and the rotating frames are not coaxial with hinged shafts of the rotating frames and the base. Compared with an existing folding mechanism, the aircraft airfoil folding and unfolding mechanism is light in weight, simple in connector, capable of reducing the mass and size, simplifying the structure,reducing the cost, reliably and synchronously unfolding, capable of being accurately positioned through a limiting and locking device, easy to operate and capable of meeting various working conditions of aircraft parking, aerial flight and the like, and the unfolding time is shorter than 1 s.
本发明提供了一种飞行器翼面折叠展开机构,包括底座、作动筒、滑块和转动架,所述的作动筒安装在底座上,作动筒的输出端连接滑块中部;所述的滑块两端铰接转动架;所述的转动架固连飞行器翼面,铰接在底座上;所述的滑块和转动架的铰接轴与转动架和底座的铰接轴不同轴。本发明重量轻,接口简单,相比现有折叠机构能够减小质量和体积,简化结构,降低成本,能够可靠同步展开,展开时间小于1s,并能利用限位和锁定装置准确定位,易于操作,能够满足飞行器的停放、空中飞行等各种工况。
