The invention relates to a high-speed train windshield mounting structure which comprises a windshield bottom frame, a windshield and a pressing plate frame. The bottom of the windshield bottom frame is adhered to a vehicle body through glue, the outer side wall of the windshield bottom frame and the vehicle body are sealed through glue, and a first groove and a second groove are machined in the windshield bottom frame. A third groove is machined in the periphery of the windshield, the periphery of the windshield is wrapped by a sealing rubber ring which is in profile modeling with the section of the end of the windshield, and the windshield wrapped by the sealing rubber ring is installed in the first groove. The outer ring of the pressing plate frame is installed in the second groove, the inner ring of the pressing plate frame is installed in the third groove, the pressing plate frame is fixedly connected with the windshield bottom frame through connecting bolts, and sealing between the pressing plate frame and the windshield and between the pressing plate frame and the windshield bottom frame is achieved through profiling sealing rubber rings. By means of the structure, smooth design of the surface of a high-speed train can be guaranteed, and aerodynamic resistance and aerodynamic noise can be reduced while rapid installation and replacement of the windshield are achieved.
本发明涉及一种高速列车挡风玻璃安装结构,包括挡风玻璃底框、挡风玻璃、压板框;挡风玻璃底框的底部用胶粘接在车体上,挡风玻璃底框的外侧壁与车体之间通过胶密封,挡风玻璃底框上加工有第一凹槽和第二凹槽;挡风玻璃的周圈加工有第三凹槽,挡风玻璃的周圈包覆有与挡风玻璃端部截面仿形的密封胶圈,包覆密封胶圈的挡风玻璃安装在第一凹槽内;压板框的外圈安装在第二凹槽内,内圈安装在第三凹槽内,压板框通过连接螺栓与挡风玻璃底框固定连接,压板框与挡风玻璃和挡风玻璃底框之间通过仿形的密封胶圈实现密封。该结构能够保证高速列车表面平顺化设计,在实现对挡风玻璃快速安装及更换的同时,还能减低气动阻力和气动噪声。
