The invention relates to an outer windshield which is used for being connected with a vehicle body of a rail transit vehicle and comprises an inflatable capsule, a connecting profile, an inflation system and an exhaust system. The inflatable capsule is of an integrated opposite-wave structure, the two ends of the inflatable capsule are connected with the connecting profiles through screws, the connecting profiles are fixedly connected with the vehicle bodies on the two sides respectively, and the middle of the inflatable capsule is of a wavy structure. According to the structure, the stability of gas pressure in the inflatable capsule is effectively guaranteed, and the air tightness between vehicle bodies is improved; due to the opposite wave type structure, the inflatable capsule has enough compression amount and stretching amount, and the overall service life of the inflatable capsule is effectively prolonged. And the inflation ports and the exhaust ports are correspondingly arranged in a staggered manner, so that rapid inflation and exhaust can be realized. And the frame is adopted to shape the waveform, so that the attractiveness is improved, and shaking or resonance in the running process of the rail transit vehicle is prevented. The inflatable capsule is simple in structure, convenient to use and operate and convenient to overhaul, and the failure rate of the outer windshield is greatly reduced.

    本发明涉及一种外风挡,用于连接轨道交通车辆的车体,包括:充气式胶囊,连接型材,充气系统,排气系统;充气式胶囊为一体式对波结构,两端部与连接型材螺钉连接,连接型材分别与两侧车体固定连接,充气式胶囊中部为具有波形的结构。该结构有效保证充气式胶囊内部气体压力的稳定并提高车体与车体之间的气密性;对波式结构使其具有足够的压缩量和拉伸量,有效延长充气式胶囊的整体寿命。充气口和排气口对应并交错布设,能够快速的充气和排气。采用框架以对波形进行定型提高美观度,防止轨道交通车辆运行过程出现抖动或共振的产生。充气式胶囊结构简单,使用操作方便,便于检修,极大的降低了外风挡的故障率。
