[0038] Embodiment 1

[0039] See also Figures 1 to 4 As shown, an embodiment of the present application provides a vehicle window assembly 1 for installation on a rail train, specifically, installed at a vehicle window of the rail train.

[0040] See also Figures 1 to 4 As shown, this embodiment provides a vehicle window assembly 1; Figure 1 This is a first structural schematic diagram of the vehicle window assembly 1 provided in this embodiment, which simply shows the appearance structure of the vehicle window assembly 1; Figure 2 This is a second structural schematic diagram of the vehicle window assembly 1 provided in this embodiment, in which a cross-sectional view of one position of the vehicle window assembly 1 in the circumferential direction is simply shown; Figure 3 This is a schematic diagram of the vehicle window assembly 1 provided in this embodiment in use, and shows the connection relationship between the vehicle window assembly 1 and the vehicle body 4 through a cross-sectional view; Figure 4 It is a schematic structural diagram of the anti-drop net 13 of the vehicle window assembly 1 provided in an embodiment of the present application when not in use.

[0041] The vehicle window assembly 1 provided in this embodiment includes an inner window frame 11, an outer window frame 10, an anti-slip net 13, a glass component and a fixing component.

[0042] The inner window frame 11 is arranged around the inner circle of the outer window frame 10 . The outer window frame 10 is used to be fixed to the vehicle body 4 , and the inner window frame 11 is used to install the glass assembly.

[0043] The glass assembly includes a first glass 12, which is a double-layer laminated glass, so that the first glass 12 has an adhesive layer 120 sandwiched between two layers of glass. The outer periphery of the first glass 12 is bonded to the inner window frame 11, and the first glass 12 faces the outside of the vehicle during use of the vehicle window assembly 1. Optionally, the first glass 12 and the inner window frame 11 are bonded by a structural adhesive 2.

[0044] The anti-slip net 13 includes a first net portion 130 and a second net portion 132 connected to the outer periphery of the first net portion 130. The first net portion 130 is pre-buried in the adhesive layer 120 of the first glass 12, and the second net portion 132 is connected to the inner window frame 11 outside the first glass 12 through a fixing component.

[0045] Specifically, the first net portion 130 of the anti-slip net 13 is placed in the adhesive layer 120 when the two layers of glass of the first glass 12 are put together, so that it is pre-embedded and bonded between the two layers of glass through the adhesive layer 120, so that the first glass 12 becomes a double-layer laminated glass with the anti-slip net 13 in the middle, and then the second net portion 132 of the anti-slip net 13 exposed outside the first glass 12 is fixed to the inner window frame 11 through a fixing component.

[0046] In addition, the first glass 12 is also bonded to the inner window frame 11, so the first glass 12 and the inner window frame 11 are not only fixed by bonding, but also fixed by the anti-detachment net 13, achieving double fixation and avoiding the first glass 12 from falling off after the bonding fixation between the two fails.

[0047] It is worth emphasizing that the addition of the anti-slip net 13 will not affect the installation, inspection, maintenance and replacement of the first glass 12, and the anti-slip net 13 will not affect the installation and positioning between the first glass 12 and the inner window frame 11 and the outer window frame 10, and can still maintain flushness without protrusion, and will not affect the appearance of the vehicle window assembly 1. Furthermore, once the anti-slip net 13 fails partially, since the anti-slip net 13 has a large area and its first net portion 130 is fixed in the adhesive layer 120 of the first glass 12, there will be obvious appearance abnormalities, which makes it easy to find the failure phenomenon.

[0048] Optionally, the adhesive layer 120 is a PVB adhesive film.

[0049] In an optional solution of this embodiment, the first mesh portion 130 is annular, the first glass 12 has a screen printing area, and the first mesh portion 130 is located in the screen printing area. In other words, the extension range of the first mesh portion 130 does not exceed the screen printing area of ​​the first glass 12, and the middle part of the first glass 12 corresponds to the hollow part of the first mesh portion 130, so as to prevent the anti-dropping mesh 13 from affecting the field of view of the first glass 12.

[0050] In an optional scheme of the present embodiment, the anti-slip net 13 also includes a ring-shaped connecting net portion 131, which is connected between the first net portion 130 and the second net portion 132, and can be bent and connected to the first net portion 130 and the second net portion 132, so that the connecting net portion 131 can change the folding angle between itself and the first net portion 130 or the second net portion 132 according to the specific cross-sectional shapes of the inner window frame 11 and the outer window frame 10, ensuring that the first net portion 130 and the second net portion 132 can be installed flatly.

[0051] like Figure 4 As shown, when the anti-slip net 13 is not in use, the connecting net portion 131 is connected to the first net portion 130 and the second net portion 132 at an obtuse angle, but because the anti-slip net 13 has a certain flexibility, the folding angle can be changed, so that when in use, the anti-slip net 13 can be connected to the first net portion 130 and the second net portion 132 at an obtuse angle. Figure 2 and Figure 3 As shown, the state of the connecting net portion 131 is adjusted to be disposed perpendicularly to both the first net portion 130 and the second net portion 132 .

[0052] In this embodiment, the anti-dropping net 13 is a woven steel wire net.

[0053] In this embodiment, the thickness of the anti-dropping net 13 is 0.5 mm±0.1 mm, for example, 0.4 mm, 0.5 mm or 0.6 mm.

[0054] In an optional solution of this embodiment, the fixing assembly includes a fastening member 15 and an annular pressing plate 14 .

[0055] The pressing plate 14 is arranged on the side of the second net portion 132 away from the inner window frame 11, and the fastening member 15 passes through the pressing plate 14, the second net portion 132, the inner window frame 11 and the outer window frame 10 in sequence, so that the second net portion 132 is pressed between the pressing plate 14 and the inner window frame 11, so that on the one hand, the outer window frame 10 and the inner window frame 11 are connected as a whole through the fastening member 15, and on the other hand, the cooperation between the fastening member 15 and the pressing plate 14 can realize the full circle press-fitting and fixing of the anti-slip net 13, thereby ensuring the connection reliability between the anti-slip net 13 and the inner window frame 11.

[0056] It is worth explaining that the so-called "ring" refers to a shape without openings that is closed around the circumference, for example, Figures 1 to 3 As shown, the outer window frame 10, the inner window frame 11, the anti-slip net 13 and the pressing plate 14 are all in the shape of a ring extending along a rectangle.

[0057] In an optional solution of this embodiment, the circumferential edge of the pressing plate 14 facing the second net portion 132 is provided with a rounded corner, which can prevent the circumferential edge of the pressing plate 14 from cutting the anti-drop net 13 .

[0058] Optionally, the pressing plate 14 is, for example, an aluminum profile.

[0059] In an optional solution of this embodiment, there are multiple fastening components 15, and the multiple fastening components 15 are arranged in sequence and at intervals along the circumference of the pressure plate 14, so as to improve the fastening reliability and improve the uniformity of the distribution of the pressing force of the pressure plate 14 on the anti-detachment net 13, thereby avoiding the pulling of the local stress of the anti-detachment net 13.

[0060] In an optional solution of this embodiment, the glass assembly further includes a second glass 16; the second glass 16 is disposed opposite to the first glass 12 at a distance and bonded to the inner window frame 11. When the vehicle window assembly 1 is in use, the second glass 16 faces the interior of the vehicle, and the second glass 16 can be, for example, a single-layer glass or a double-layer laminated glass, so that by combining the first glass 12 and the second glass 16, the heat insulation performance and sound insulation performance of the vehicle window assembly 1 can be improved.
