Integral high-speed train inner windshield

Abstract

An integral inner windshield for a high-speed train is mainly structurally characterized in that a plurality of integral ring-shaped rubber air bags are combined into a rubber air bag group, one rubber air bag group is embedded and fixed in a clamping groove of a train end mounting frame of a front train, and the other rubber air bag group is embedded and fixed in a clamping groove of a train end mounting frame of a rear train; the vehicle end mounting frame is fixed to the end face of a vehicle through bolts, and a lower supporting beam is fixed to a front vehicle coupler. An upper support beam is fixed on a passage pedal of the front vehicle; the upper supporting beam and the lower supporting beam are fixedly connected with the top face and the bottom face of the connecting frame bottom frame respectively. The front side and the rear side of the connecting frame are respectively embedded and fixed with rubber air bag groups of a front vehicle and a rear vehicle; the rubber air bag is connected with an inflation air source through a controllable air valve, and the controllable air valve is further electrically connected with an air source control system. The inner windshield has excellent air tightness, heat insulation performance, sound insulation performance and noise reduction performance; and installation and maintenance are convenient, and a safer, more comfortable and more attractive riding environment can be provided for passengers.

Description

technical field [0001] The invention relates to a windshield at the connection between trains and vehicles, in particular to an inner windshield of a high-speed train. Background technique [0002] The connection between the cars of the train is a soft connection, which allows the adjacent cars of the running train to have a certain relative movement at the connection, so that the train has the ability to pass through curves. The inner and outer windshields need to be installed at the soft connection of the vehicle to isolate the inner space of the shield (vehicle) at the connection from the outside: so that passengers can walk through the connection safely and comfortably, while avoiding rain, snow, wind and sand on the connection device. infringement. Since the speed of high-speed trains is over 200km / h, a small gap can cause a large amount of outside air to quickly enter the car, which seriously reduces the heat insulation and sound insulation performance of the car body...

AI Technical Summary

Problems solved by technology

Usually the entire bellows is an inverted U-shaped structure, the lower part is not closed, its airtightness is poor, and its heat insulation and sound insulation performance is not good.

The bellows-type inner windshield (inner bellows) used in the patent No. 2018212648983 "A Maglev Train Inner Windshield and Its Installation Frame" is integrally closed, but there is a gap between the V-shaped sheet rubber or canvas material and the installation frame. gap, its air tightness is poor, and the windshield material is a single-layer sheet material, its heat insulation performance, especially sound insulation and noise reduction performance is not very ideal; and the tooth shape of the "W" type bellows structure The transition of the concave-convex shape is not smooth, it is not beautiful, and it also makes the passenger experience poor when passing
