The invention belongs to the field of design of hinge connection inward and upward opening aircraft cabin door guide structures, and particularly relates to a hinge connection inward and upward opening aircraft cabin door guide structure. In the cabin door opening and closing process, a guide matching assembly and a linear guide groove arranged at the far end of a hinge are used for guiding; the problems of shaking, inaccurate movement position and the like in the opening and closing process of the cabin door can be solved, the structure is simple, the overall weight of the aircraft cannot be greatly increased, limiting can be conducted, opening and closing of the cabin door are prevented from exceeding the limit, the linear guide groove formed in the aircraft body replaces an arc-shaped guide groove, the machining manufacturability is good, and the cost is low. When the cabin door is opened and closed, clamping stagnation between the cabin door and the idler wheel can be avoided, in addition, in the cabin door opening and closing process, the installation shaft track line is designed, the arc-shaped guide groove idler wheel reciprocates in the arc-shaped limiting groove, the structural space can be fully utilized, and the situation that the overall weight of an airplane is greatly increased is avoided.
本申请属于铰链连接向内向上打开飞机舱门导向结构设计领域,具体涉及一种铰链连接向内向上打开飞机舱门导向结构,在舱门打开、关闭过程中,利用在铰链远端设置的导向配合组件、直线导向槽进行导向,可避免舱门打开、关闭过程中发生晃动、运动位置不准确等问题,结构简单,不会较大增加飞机整体的重量,并能够进行限位,避免舱门打开、关闭超限,且以在机体上设置的直线导向槽取代弧形的导向槽,加工工艺性好,可避免在舱门打开、关闭过程中,与滚轮间发生卡滞,此外,在舱门打开、关闭过程中,通过对安装轴轨迹线的设计,使弧形导向槽滚轮在弧形限位槽中做往复运动,可充分利用结构空间,避免使较大增加飞机整体的重量。
