Detailed Description

In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

According to the rail vehicle provided by the embodiment of the application, the rail vehicle comprises a plurality of carriages, each carriage comprises a vehicle body 200 and a plurality of windows arranged on the vehicle body 200, and part of the windows are emergency windows 100; the rail vehicle that this application embodiment provided includes a plurality of emergent window 100, and each emergent window 100 crisscross setting is on the lateral wall of automobile body 200 to the passenger looks for emergent window 100 nearby, makes the passenger evacuate fast.

As shown in fig. 1 to 4, in order to increase the evacuation speed of passengers based on the above embodiment, an emergency window 100 according to an embodiment of the present application includes a window panel 10 and a sealing ring 20 provided on the window panel 10; the window panel 10 may be made of a material having light transmission and high strength, for example, the window panel 10 may be made of a Polycarbonate (PC) panel, that is, the window panel 10 is also referred to as a PC panel. The window panel 10 is configured to conform to the shape of the opening of the emergency window 100. the window panel 10 in this embodiment may be a rectangular panel, and may be 11.7mm thick, to provide greater structural strength.

The sealing ring 20 is arranged at the edge of the window plate 10 along the circumferential direction of the window of the vehicle body, the sealing ring 20 can be an H-shaped sealing ring 20, the sealing ring 20 comprises a first sealing groove 21 and a second sealing groove 22 which are oppositely arranged, the sealing ring 20 is connected with the window plate 10 in a sealing mode through the first sealing groove 21, and the sealing ring 20 is connected with the window of the vehicle body in a sealing mode through the second sealing groove 22, so that the window plate 10 can be detachably connected to the window of the vehicle body.

The emergency window 100 further comprises a clamping strip 50, a protective handle 40 and a handle 30; wherein, the sealing washer 20 is provided with the third seal groove towards one side of automobile body, and the third seal groove sets up along sealing washer 20 annular to be located sealing washer 20 towards the side. The third seal groove is used for installing a clamping strip 50, the clamping strip 50 is an annular mounting strip, one side of the clamping strip 50 is embedded in the third seal groove, and the other side of the clamping strip 50 is connected with one end of the protective handle 40.

Protection handle 40 is rectangular strip shape, and protection handle 40 and luffer board 10 parallel arrangement form the protection space of handle 30 between the two, and the one end that protection handle 40 kept away from card strip 50 is the free end, and the one end that protection handle 40 kept away from card strip 50 is not fixed promptly to can laminate the setting on luffer board 10. The handle 30 is located between the protection handle 40 and the window panel 10, and the handle 30 is connected to the edge of the window panel 10 and can rotate relative to the window panel 10, so that the rescuer can pull the handle 30 from different angles to detach the window panel 10 from the sealing ring 20, thereby forming a safe passage for emergency escape.

When an emergency car window needs to be opened for emergency escape, personnel in the car can pull the protective handle 40, and the protective handle 40 is connected with the clamping strip 50, so that the protective handle 40 can drive the clamping strip 50 to fall off from the sealing ring 20; at this time, after the clamping strip 50 falls off from the sealing ring 20, the gap between the sealing ring 20 and the window panel 10 is increased, so that the bonding force between the window panel 10 and the sealing ring 20 can be reduced, and the window panel 10 can be detached from the sealing ring 20 by applying a small force to the handle 30, thereby forming a safety channel for emergency escape; at the same time, the gasket 20 remains sealingly connected to the window of the vehicle body 200.

According to the emergency window and the rail vehicle, the window plate 10 is detached from the sealing ring 20 in a mode of pulling the protective handle 40 and the handle 30, so that the existing mode of hammering the window plate 10 in an emergency mode is replaced, and therefore the emergency window provided by the embodiment of the application does not need to search tools such as an emergency hammer and the like, and the rescue efficiency is improved; after a safety passage for emergency escape is formed, the sealing ring 20 is still kept on the window of the vehicle body, so that the escape personnel can be protected, and the escape personnel can be prevented from secondary damage when passing through the escape passage.

Furthermore, the emergency safety channel can be formed without destroying the structure of the window panel 10, and when the window panel 10 is recovered, the window panel 10 only needs to be installed in the second sealing groove 22 of the sealing ring 20, and the window panel can be installed during the running time of the vehicle without removing and refilling sealing glue and/or installing and detaching fasteners and the like; the recovery time and cost after the emergency window is opened can be reduced.

It is understood that, in the present embodiment, the sealing ring 20 may also be provided with a sealing groove on the side facing the vehicle body outer side and the clamping strip 50 is installed in the sealing groove; when needs are rescued outside the car, usable instruments such as crowbar will block strip 50 and dismantle from sealing washer 20 from the outer card strip 50 kneck of car to reduce the cohesion between sealing washer 20 and the luffer board 10, thereby reduce the operating force of car outer rescue, in order to satisfy different rescue environment needs, promote rescue efficiency.

On the basis of the above embodiment, in order to enhance the sealing effect between the sealing ring 20 and the window panel 10, the size of the opening of the first sealing groove 21 is smaller than the size of the bottom surface thereof, so that the sealing ring 20 is tightly clamped on the window panel 10 through the first sealing groove 21, and the sealing performance between the sealing ring 20 and the window panel 10 is further improved. Similarly, the opening of the second seal groove 22 is designed with reference to the opening of the first seal groove 21, and details are not repeated here, so that the sealing performance of the seal ring 20 and the window of the vehicle window can be improved.
