[0042] In specific implementation, the thickness of the adjustment pad is not limited and can be set according to actual conditions.

[0043] Figure 6 A schematic structural diagram of a window assembly of a rail vehicle window structure provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, further, the vehicle window assembly 20 includes a vehicle window glass 201 and a window frame 202 , and the vehicle window glass 201 and the window frame 202 are connected by a first adhesive 203 .

[0044] Figure 7 A structural diagram of a window frame of a rail vehicle window structure provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, further, the window frame 202 includes a window frame body 2021, and a first connecting plate 2022 is provided on the top surface of the window frame body 2021, which is parallel to the plane of the vehicle window glass 201, and a second connecting plate 2023 is obliquely arranged between the middle part of the first connecting plate 2022 on the side away from the vehicle window glass 201 and the window frame body 2021, and the second connecting plate 2023 is connected to the inner surface of the interior wall panel 50, and at least one first through hole for the fastener 30 to pass through is opened on the second connecting plate 2023, and a first installation groove 2024 for installing the rubber strip 40 is formed between the upper part of the first connecting plate 2022 on the side away from the vehicle window glass 201 and the top of the second connecting plate 2023; the bottom end surface of the window frame body 2021 close to the vehicle window glass 201 is provided with a second installation groove 2025, and a rubber stop strip 204 is stuck in the second installation groove 2025, which can block the sealant, effectively reducing the amount of sealant used, and making it easier to remove the sealant when replacing the vehicle window.

[0045] In a specific implementation, the shape of the first through hole is not limited, and any fastener can pass through it.

[0046] Specifically, the window frame is a single aluminum frame, which is beneficial to the lightweight of the vehicle and can effectively reduce the material cost of the window assembly.

[0047] Furthermore, the window frame body 2021, the connecting plate 2022 and the second mounting groove 2025 close to the window glass 201 are all connected to the window glass 201 through the first adhesive 203, so that the window glass and the window frame are bonded and fixed by the first adhesive and play a sealing role.

[0048] Furthermore, a second through hole for the fastener 30 to pass through is provided on the window frame body 2021 below each first through hole, and the bottom of the second through hole corresponds to the notch of the slide groove 101 provided on the vehicle body 10 .

[0049] Specifically, the second through hole is a waist-shaped hole. Through the cooperation of the slide groove on the vehicle body and the waist-shaped hole on the window frame, it is convenient to adjust various parts of the window assembly when it is installed on the vehicle body. There is no need to repeatedly disassemble the window assembly for adjustment, which effectively saves installation time, thereby improving the installation efficiency of the window assembly, saving working hours and reducing labor costs.

[0050] In a specific implementation, the greater the number of first through holes and second through holes, the greater the number of fasteners used, and the more stable the connection between the vehicle window assembly and the vehicle body.

[0051] Furthermore, the vehicle window glass 201 includes an outer layer of glass 2011 and an inner layer of glass 2012. The outer layer of glass 2011 and the inner layer of glass 2012 are connected by a second adhesive 2013 to form a hollow glass between the outer layer of glass 2011 and the inner layer of glass 2012, which also plays a sealing role. A molecular sieve 2014 is placed in the hollow glass to play a role of drying and moisture absorption. The inner surfaces of the outer layer of glass 2011 and the inner layer of glass 2012 near the window frame 202 are printed with black screen printing 215 to prevent aging of the second adhesive.

[0052] Specifically, the width and length of the outer glass 2011 are greater than the width and length of the inner glass 2012 .

[0053] In a specific implementation, the printing width of the black silk screen printing 2015 on the outer glass 2011 is 40 mm, and the highest point of the printing width of the black silk screen printing 2015 on the inner glass 2012 is the same as the highest point of the printing width of the black silk screen printing 2015 on the outer glass 2011.

[0054] Furthermore, the fastener 30 is a screw, which is easy to install, fasten and remove.

[0055] The installation and fixing method adopted between the vehicle body and the window assembly of the present application is not easy to cause deformation of the vehicle body, improves the installation strength of the vehicle body and the window assembly, and realizes the rapid installation and disassembly of the window assembly, especially in the later operation, it is convenient to replace the window after it is accidentally broken.

[0056] Figure 8 A schematic structural diagram of a rail vehicle body provided in an embodiment of the present application is provided. Figure 9 Another structural diagram of a rail vehicle body provided in an embodiment of the present application is shown in FIG. Figure 8 and Figure 9 As shown, the present application also provides a rail vehicle, comprising a car body 10 and a window structure arranged on the car body 10, wherein the car body 10 is provided with a slide groove 101 with a notch facing the window structure at the installation position with the window structure, and the window structure is the rail vehicle window structure described in any one of the above items.

[0057] Furthermore, the width of the vehicle body providing a mounting location for the vehicle window assembly is L2, and the distance between the center line of the slide groove perpendicular to the axis of the fastener and the side of the vehicle body close to the vehicle window assembly is L1.

[0058] Specifically, L2 is 45 mm and L1 is 35.5 mm.

[0059] like Figure 9 As shown, in specific implementation, L2 can be designed according to strength requirements so that the vehicle body structure can adapt to vehicles with high speed levels and have better strength.

[0060] The rail vehicle provided in the embodiment of the present application has the same technical effect as the above-mentioned rail vehicle window structure, and the slide groove provided on the vehicle body changes the installation interface of the window assembly, thereby enhancing the strength of the vehicle body.

[0061] The present application also provides a method for installing a rail vehicle window structure, comprising the following steps:

[0062] S10, when installing the window assembly 20, place the window assembly 20 at the installation location of the vehicle body 10 and pre-tighten it with the fastener 30; specifically including:

[0063] S101, the fastener 30 sequentially passes through the second through hole on the window frame body 2021, the adjustment pad 70, and the slide groove 101 on the vehicle body 10;

[0064] S102, measuring the gap between the window assembly 20 and the vehicle body 10, if the gap is less than or equal to 7 mm, proceed to the next step;

[0065] Otherwise, add or reduce the adjustment pad 70 until the gap is ≤ 7 mm;

[0066] S20, adjusting the window assembly 20 to be flush with the vehicle body 10 and fastening it with a fastener 30;

[0067] S30, applying sealant 60 at the gap to seal the gap between the window assembly 20 and the vehicle body 10;

[0068] S40, installing interior wall panels 50;

[0069] S50, installing the rubber strip 40 into the slide groove 101, and the installation is completed;

[0070] S60, when the window assembly 20 needs to be replaced, the rubber strip 40 is removed from the first mounting groove 2024 to expose the fastener 30, then the fastener 30 is removed and the sealant 60 is removed to separate the window assembly 20 from the vehicle body 10, and then the above steps are repeated to replace the window assembly 20.

[0071] Furthermore, in step S102, the gap between the window assembly and the vehicle body is 7 mm or 5 mm, which makes the exposed glue gap small, beautiful, and takes up little internal space, and saves the amount of sealant, reduces the cost of using sealant, and at the same time, increases the width of the visible area of ​​the same large window glass, thereby improving the visual comfort of passengers.

[0072] Specifically, in step S60, the time required to replace the window assembly is approximately 16 hours, of which the time for removing and cleaning the sealant is 1.5 hours, the time for installing and adjusting the window is 1 hour, the time for sealing construction is 1.5 hours, and the time for keeping the vehicle moving after sealing is 12 hours. The above method effectively shortens the time required to replace the window.
