The invention discloses a sealing structure suitable for a double-leaf sliding plug door of an inter-city and urban motor train unit, and belongs to the technical field of sliding plug doors of rail transit vehicles. The sealing frame is fixedly connected with the vehicle body profile; the auxiliary locks are arranged on the two sides of the sealing frame, and the door plate is pressed through the auxiliary locks; wherein rubber strips are distributed in the circumferential direction of the door plates, the rubber strips at the center joint position of the two door plates are in butt joint in an embedded mode, and the sealing frame and the rubber strips are of an integrally-formed structure. The sliding plug door is reliable in structure and good in sealing performance, the airtight index requirement of a whole vehicle at the speed grade of 200 km/h for a sliding plug door system is met, and the requirement of the whole vehicle at the speed grade of 200 km/h for the airtight index of the sliding plug door system under the large passenger flow volume is met. In addition, the sealing structure can adapt to vibration and impact influences caused by the fact that vehicles with the speed grade of 200 km/h run under the working condition AW3.

    本发明公开了一种适用于城际及市域动车组双扇塞拉门的密封结构,属于轨道交通车辆塞拉门技术领域,本发明设置有两扇门板;与车体型材固定连接的密封框;以及设置在所述密封框两侧的辅助锁,通过所述辅助锁压紧所述门板;其中,所述门板周向布设有胶条,且两扇所述门板中缝位置的所述胶条以嵌入的形式对接,所述密封框和所述胶条均为一体成型结构,本发明结构可靠,密封性好,即满足200km/h速度等级整车对塞拉门系统气密指标要求,又满足大客流量下,乘客快速乘降的要求,且密封结构能适应200km/h速度等级车辆AW3工况运行的所带来的振动、冲击影响。
