Lightweight self-locking type large-angle opening and closing cover plate structure
The invention belongs to the technical field of railway vehicles, and relates to a light-weight self-locking type large-angle opening and closing cover plate structure which comprises a cover plate, a sliding groove and a connecting rod type hinge. Wherein the sliding groove is fixed to the inner side of the cover plate, and the connecting rod type hinge comprises a first mounting base, a second mounting base, a main lifting arm, an auxiliary lifting arm, a main rotating rod and an auxiliary rotating rod; the first mounting seat is fixedly mounted on a vehicle body, the second mounting seat is fixedly mounted on a sliding groove, the upper ends of the main lifting arm and the auxiliary lifting arm are hinged to the first mounting seat, the upper ends of the main rotating rod and the auxiliary rotating rod are hinged to the second mounting seat, and the lower end of the main lifting arm is hinged to the lower end of the auxiliary rotating rod. The lower end of the auxiliary lifting arm is hinged to the lower end of the main rotating rod, and the main rotating rod is hinged to the main lifting arm, so that the connecting rod type hinge forms two quadrilateral structures. The cover plate structure is light in weight and high in impact load resistance, a larger (120-degree) opening angle can be achieved, the maintenance space is increased, and the maintenance efficiency is improved.
本发明属于轨道车辆技术领域，涉及一种轻量化自锁式大角度的开闭罩板结构，该罩板结构包括罩板、滑槽、连杆式铰链；其中，所述滑槽固定在罩板的内侧，所述连杆式铰链包括第一安装座、第二安装座、主吊臂、辅助吊臂、主转杆、副转杆；所述第一安装座安装固定在车体上，所述第二安装座安装固定在滑槽上，所述主吊臂、辅助吊臂的上端与第一安装座铰接，所述主转杆、副转杆的上端与第二安装座铰接，所述主吊臂的下端与副转杆的下端铰接，所述辅助吊臂的下端与主转杆的下端铰接，所述主转杆与主吊臂之间铰接，使连杆式铰链形成2个四边形结构。该罩板结构重量轻、抗冲击载荷能力强，且能实现更大(120度)的打开角度，增加检修空间，提高检修效率。
