The invention relates to the technical field of the structure design of an opening and closing structure of a large curvature curved surface skin, in particular to a opening and closing structure of a large curvature curved surface skin, with an opening frame on the curved surface skin, and two corners fixed inside the curved surface skin, both of which are located on one side of the opening frame; the corners include a fixing part and a supporting part, the fixing part is fixed with the curved surface skin, the supporting part is provided with a sliding groove, and the sliding groove is close The distance between the end and the surface skin is less than that between the end of the sliding groove far from the mouth frame and the surface skin; the rocker arm and the mouth cover are fixed, and the rocker arm includes the rocker arm base, the vertical bar and the rotating shaft. The cross section of the rocker arm base is curved, and the vertical bar is located on both sides of the rocker arm base. One end of the rotating shaft is fixed on the vertical bar, and the other end is extended into the sliding groove; the articulated arm is replaced by a sliding shaft. Meanwhile, the sliding component is set on the inside of the skin to meet the structural scheme with large opening and closing angle and easy sealing of the mouth cover, so as to reduce the space requirement.

大曲率曲面蒙皮的口盖开合结构
本专利技术涉及口盖结构设计
,特别涉及大曲率曲面蒙皮的口盖开合结构。
技术介绍
在大曲率区域设计口盖时,经常面对转轴难以布置、打开角度受曲面限制、开合结构占用空间较大、口盖难以密封等问题,有的口盖开合结构开合角度大、占用空间小,但无法密封,有的示口盖开合结构占用空间小、可以密封,但打开角度不大。
技术实现思路
为克服上述现有技术存在的至少一种缺陷,本专利技术提供了一种大曲率曲面蒙皮的口盖开合结构,曲面蒙皮上开有口框,曲面蒙皮内侧固定有两个角片,两个角片均位于口框的一侧;角片包括固定部和支撑部,固定部与曲面蒙皮相固定,支撑部上开有滑槽,滑槽靠近口框的一端与曲面蒙皮之间的距离小于滑槽远离口框的一端与曲面蒙皮之间的距离;摇臂和口盖相固定,摇臂包括摇臂基体、立筋和转轴,摇臂基体的截面呈弧形,立筋设置在摇臂基体两侧,转轴的一端固定在立筋上,另一端伸入到滑槽内。优选的,滑槽呈弧形,滑槽的弧形向远离曲面蒙皮的方向拱起。优选的,角片位于口框的下方,固定部的截面呈L型,其两条边互相垂直,支撑部呈片状,两个角片的支撑部相平行。优选的,滑槽贯穿支撑部,转 ...
