A side opening type front cabin door system belongs to the field of cabin doors of unmanned aerial vehicles and comprises a front cabin door skin, a nose bulkhead, a front fuselage bulkhead, a foldable two-connecting-rod mechanism, an air supporting rod assembly and a locking assembly. The foldable two-connecting-rod mechanism comprises connecting rod mechanisms, a rotating shaft and connecting rod supports, the first connecting rod mechanism is connected with the second connecting rod mechanism through a first rotating shaft, the other end of the first connecting rod mechanism is connected with the first connecting rod support through a second rotating shaft, and the other end of the second connecting rod mechanism is connected with the second connecting rod support through a locking shaft. The first connecting rod support is connected to the front machine body bulkhead through two bolts, similarly, the second connecting rod support is connected to the machine head bulkhead through two bolts, the foldable two-connecting-rod mechanism moves forwards in the initial stage of opening of the front cabin door, the foldable two-connecting-rod mechanism moves around a rotating shaft subsequently, and the structural interference problem is avoided. The side opening type front cabin door is opened and closed, the structure is simple, the force transmission path is short, the weight is small, and extra driving force and control systems are not needed.

    一种侧开式前舱门系统,属于无人机舱门领域,包括前舱门蒙皮、机头隔框、前机身隔框、可折叠二连杆机构、气撑杆组件、锁闭组件。所述的可折叠二连杆机构包括连杆机构,转动轴,连杆支座,第一连杆机构与第二连杆机构通过第一转轴相连接,第一连杆机构另一端与第一连杆支座通过第二转轴相连接,第二连杆机构另一端与第二连杆支座通过锁定轴相连接,第一连杆支座通过2个螺栓连接于前机身隔框,同样,第二连杆支座通过2个螺栓连接于机头隔框,可折叠二连杆机构在前舱门打开的初始阶段为前移运动,后续为绕转轴运动,避免了结构上的干涉问题。本发明实现了侧开式前舱门的打开与关闭,结构简单,传力路径短,重量小,无需额外的驱动力和控制系统。
