Abstract
Description
Technical Field
[0001] This application relates to the field of glass product technology, particularly to car windows, frameless car doors, and vehicles. Background Technology
[0002] Frameless doors eliminate the window frames of traditional framed doors, achieving a sleek and minimalist appearance while reducing blind spots and expanding the driver's field of vision. Frameless doors consist of a window and a door, with the window connected to the door. In existing technology, the window glass of frameless doors is typically cut and then edge-ground using a sanding machine, resulting in a rough surface on the sides of the window glass. During the raising or lowering of the frameless door window, the side of the window glass rubs against the vehicle's weatherstripping, causing wear and tear. This can compromise the vehicle's sealing performance, leading to water leakage and other adverse effects. Summary of the Invention
[0003] The purpose of this application is to provide a vehicle window that can reduce the wear on the sealing strip during the window raising and lowering process, improve the service life of the sealing strip, and ensure the vehicle's sealing performance.
[0004] The first aspect of this application provides a vehicle window, the vehicle window including a window glass and a first wear-resistant layer, the window glass including a first glass panel, the first glass panel including an inner surface, a first surface and a first side surface, the inner surface and the first surface being disposed opposite to each other along the thickness direction of the vehicle window, and the first side surface being located between the inner surface and the first surface.
[0005] The first wear-resistant layer covers the first side surface and is adjacent to the inner surface;
[0006] The first wear-resistant layer covers at least 10% of the area of the first side surface.
[0007] Understandably, a first wear-resistant layer with a smooth surface is provided on the first side. This window can be applied to frameless doors. When the window of the frameless door is closed, the first wear-resistant layer slides along the first sealing strip and deforms it by compressing the first sealing strip. The friction between the first wear-resistant layer and the first sealing strip is small, resulting in less wear on the first sealing strip. This extends the service life of the first sealing strip, avoids frequent replacements, and reduces costs. Less wear on the first sealing strip ensures the airtightness of the frameless door to the vehicle, preventing water seepage between the top of the frameless door and the body. It also ensures that the vehicle's noise, vibration, and harshness (NVH) performance meets usage requirements. Less wear on the first sealing strip also prevents abnormal noises caused by rapid aging of the first sealing strip.
[0008] In one possible implementation, the first wear-resistant layer covers 30%-100% of the area of the first side.
[0009] In one possible implementation, the first wear-resistant layer partially covers the inner surface.
[0010] In one possible implementation, the first wear-resistant layer completely covers the first side and partially covers the first surface.
[0011] In one possible implementation, the roughness Ra1 of the first wear-resistant layer is in the range of Ra1≤0.5μm.
[0012] In one possible implementation, the pencil hardness HB1 of the first wear-resistant layer is in the range of: HB1≥9H.
[0013] In one possible implementation, the surface energy G1 of the first wear-resistant layer is in the range of G1≤30dyn. In another possible implementation, the first wear-resistant layer is a uniform thickness layer, and the thickness t1 of the first wear-resistant layer is in the range of t1≥2μm.
[0014] In one possible implementation, the first wear-resistant layer is a layer of unequal thickness, wherein the maximum thickness of the first wear-resistant layer is t1. max The range is: t1 max ≥2μm.
[0015] In one possible implementation, the first glass panel further includes a second side surface and a second wear-resistant layer. Along the thickness direction of the window, the second side surface is located between the inner surface and the first surface, and one end of the second side surface is connected to the first side surface.
[0016] The second wear-resistant layer covers the second side surface and is adjacent to the inner surface;
[0017] The second wear-resistant layer covers at least 10% of the area of the second side.
[0018] In one possible implementation, the window glass further includes a third side surface and a third wear-resistant layer. Along the thickness direction of the window, the third side surface is located between the inner surface and the first surface, and one end of the third side surface is connected to the first side surface. The second side surface and the third side surface are arranged opposite to each other along the width direction of the window.
[0019] The third wear-resistant layer covers the third side surface and is adjacent to the inner surface;
[0020] The third wear-resistant layer covers at least 10% of the area of the third side surface.
[0021] In one possible implementation, the window includes a functional layer that covers the inner surface of the first glass panel and is connected to the first wear-resistant layer.
[0022] In one possible implementation, the window further includes a second glass panel and an intermediate layer, the second glass panel including an outer surface and a second surface, the outer surface and the second surface being disposed opposite to each other along the thickness direction of the window;
[0023] The intermediate layer is sandwiched between the first glass plate and the second glass plate, with the inner surface facing away from the intermediate layer and the outer surface facing away from the intermediate layer.
[0024] A second aspect of this application provides a frameless vehicle door for use in a vehicle, comprising a door and a window as described above, the window being mounted on the door.
[0025] A third aspect of this application provides a vehicle including a body and a frameless door as described above, the body having a frame, a first sealing strip being provided on the top of the frame, and a second sealing strip and a third sealing strip being provided on the front and rear sides of the frame, respectively.
[0026] The frameless door is mounted on the vehicle frame, and the inner surface of the first glass panel is in contact with the first sealing strip, the second sealing strip, and the third sealing strip.
[0027] The beneficial effects of this application are as follows: A first wear-resistant layer with a smooth surface is provided on the first side. Furthermore, a second wear-resistant layer can be provided on the second side and / or a third wear-resistant layer on the third side. When the frameless door window is closed, the friction between the first wear-resistant layer and the first sealing strip is low, resulting in less wear on the first sealing strip; the friction between the second wear-resistant layer and the second sealing strip is low, resulting in less wear on the second sealing strip; the friction between the third wear-resistant layer and the third sealing strip is low, resulting in less wear on the third sealing strip. Therefore, the service life of the first, second, and third sealing strips can be extended, avoiding frequent replacement of the sealing strips and reducing costs. In addition, the airtightness of the frameless door to the vehicle can be ensured, preventing adverse effects such as water seepage between the top of the frameless door and the vehicle body. It can even ensure that the vehicle's noise, vibration, and harshness (NVH) performance meets the usage requirements. Attached Figure Description

[0039] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0040] Please see Figure 1Vehicle 1000 includes a body 400 and a frameless door 300. The body 400 has a frame, and the frameless door 300 is connected to the frame of the body 400. The frameless door 300 includes a door 200 and a window 100, the window 100 being mounted on the door 200 as a viewing window. The window 100 includes window glass 10, which has an inner surface 111. Vehicle 1000 also includes a first sealing strip 500, a second sealing strip, and a third sealing strip. The first sealing strip 500 is connected to the top of the frame. The second and third sealing strips are connected to the front and rear sides of the frame, respectively. When the frameless door 300 is closed and the window 100 is closed, the inner surface 111 of the window glass 10 is in contact with the first sealing strip 500, the second sealing strip, and the third sealing strip to ensure the airtightness of vehicle 1000.
[0041] It is understandable that the first sealing strip 500, the second sealing strip, and the third sealing strip can be separate structural components or integrally formed structural components.
[0042] It should be noted that, for ease of description, the definition is... Figure 2 The width direction of the window 100 shown is the X-axis direction, the height direction is the Y-axis direction, and the thickness direction is the Z-axis direction. The X-axis, Y-axis, and Z-axis directions are all perpendicular to each other. In this application, directional terms such as "top" and "bottom" refer to the direction facing the positive Z-axis, and "bottom" refers to the direction facing the negative Z-axis. Similar descriptions in the following text can be understood in the same way.
[0043] Please see Figure 2 This application provides a first embodiment of a window 100 for a frameless car door 300. In this embodiment, the window 100 includes a window glass 10 and a first wear-resistant layer 21. The first wear-resistant layer 21 is attached to the surface of the window glass 10.
[0044] Please refer to the following: Figures 2 to 4 In this embodiment, the vehicle window glass 10 includes a first glass panel 11. Specifically, the first glass panel 11 has an irregular quadrilateral shape. The first glass panel 11 is tempered single-layer glass. The first glass panel 11 includes an inner surface 111 and a first surface 112, which are arranged opposite to each other along the thickness direction of the first glass panel 11. The first glass panel 11 also includes a first side surface 113, a second side surface 114, a third side surface 115, and a fourth side surface 116. Along the thickness direction of the first glass panel 11, the first side surface 113, the second side surface 114, the third side surface 115, and the fourth side surface 116 are all located between the inner surface 111 and the first surface 112. Along the height direction of the first glass panel 11, the first side surface 113 and the fourth side surface 116 are arranged opposite to each other. Along the width direction of the first glass panel 11, the second side surface 114 and the third side surface 115 are arranged opposite to each other and are located between the first side surface 113 and the fourth side surface 116.
[0045] In this embodiment, the first side surface 113 and the fourth side surface 116 are generally arc-shaped surfaces, that is, the shapes of the first side surface 113 and the fourth side surface 116 are arc-shaped or semi-circular. Specifically, along the height direction of the first glass plate 11, the first side surface 113 and the fourth side surface 116 protrude in opposite directions. The first side surface 113, the second side surface 114, the third side surface 115, and the fourth side surface 116 are all formed with multiple protrusions. The height of each protrusion is negligible relative to the thickness of the window glass 10. It can be understood that the first side surface 113, the second side surface 114, the third side surface 115, and the fourth side surface 116 are rough surfaces. It should be noted that the first side surface 113, the second side surface 114, the third side surface 115, and the fourth side surface 116 are formed by grinding the edges of the first glass plate 11 with a sandblasting machine.
[0046] It should be noted that in other embodiments, the window glass 10 may also have other shapes. For example, the window glass 10 is an irregular triangular shape. The window glass 10 includes a first side surface 113 and a fourth side surface 116 disposed opposite to each other along the height direction of the window glass 10, and a second side surface 114 connecting the first side surface 113 and the fourth side surface 116. The shape of the window glass 10 is not limited to the shape described above; it can be any shape that meets the usage requirements of the window 100. This application does not strictly limit the shape of the window glass 10.
[0047] Along the thickness direction of the window glass 10, the first side surface 113 near the inner surface 111 has a first friction area 1131. The first friction area 1131 is adjacent to the inner surface 111. The first friction area 1131 is an elongated area and extends along the width direction (X-axis direction) of the window glass 10. The first friction area 1131 is defined as the area on the first side surface 113 of the window glass 10 that rubs against the first sealing strip 500 during the raising and lowering of the window 100 when the frameless door 300 is closed. It can be understood that when the frameless door 300 is closed, the first friction area 1131 of the window glass 10 rubs against the first sealing strip 500 during the raising and lowering of the window 100.
[0048] In this embodiment, along the width direction of the second side surface 114, the side of the second side surface 114 near the inner surface 111 has a second friction area 1141. The second friction area 1141 is adjacent to the inner surface 111. The second friction area 1141 is an elongated area and extends along the height direction of the window glass 10. The second friction area 1141 is defined as the area on the second side surface 114 of the window glass 10 that rubs against the second sealing strip during the raising and lowering process of the window 100 when the frameless door 300 is closed. It can be understood that when the frameless door 300 is closed, during the raising and lowering process of the window 100, the second friction area 1141 of the window glass 10 rubs against the second sealing strip.
[0049] Along the width direction of the third side surface 115, the side of the third side surface 115 closest to the inner surface 111 has a third friction area 1151. The third friction area 1151 is an elongated area and extends along the height direction of the window glass 10. The third friction area 1151 is defined as: the area on the third side surface 115 of the window glass 10 that rubs against the third sealing strip during the raising and lowering of the window 100 when the frameless door 300 is closed. It can be understood that when the frameless door 300 is closed, during the raising and lowering of the window 100, the third friction area 1151 of the window glass 10 rubs against the third sealing strip.
[0050] In this embodiment, the first wear-resistant layer 21 is elongated and extends along the width of the window glass 10. The first wear-resistant layer 21 covers the first friction area 1131 and encloses multiple protrusions of the first friction area 1131. That is, the first wear-resistant layer 21 covers the first side surface 113 and is adjacent to the inner surface 111; the coverage area of the first wear-resistant layer 21 on the first side surface 113 is at least 10% of the area of the first side surface 113, specifically 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, etc. It can be understood that "coverage" includes complete coverage and partial coverage.
[0051] In this embodiment, for example, the first side 113 is semi-circular in shape, and the first wear-resistant layer 21 is C-shaped.
[0052] In this embodiment, preferably, the first wear-resistant layer 21 covers 30%-100% of the area of the first side surface 113. Please refer to the following reference. Figure 2 , Figure 3 and Figure 4 Along the thickness direction of the window glass 100, the first wear-resistant layer 21 extends from the first junction (not shown in the figure) between the inner surface 111 and the first side surface 113 in a direction away from the first junction.
[0053] In one implementation, please refer to Figure 3 The first wear-resistant layer 21 covers 50% of the area of the first side surface 113.
[0054] In another implementation, please refer to Figure 4 The first wear-resistant layer 21 covers 100% of the area of the first side surface 113.
[0055] In other embodiments, the first wear-resistant layer 21 may completely cover the first side surface 113 and partially cover the inner surface 111 and / or the first surface 112. In this case, the coverage area of the first wear-resistant layer 21 on the first side surface 113 accounts for 100% of the area of the first side surface 113, and the first wear-resistant layer 21 has a certain coverage area on the inner surface 111 and / or the first surface 112.
[0056] In other embodiments, the first wear-resistant layer 21 may also partially cover the first side surface 113 and partially cover the inner surface 111. In this case, the coverage area of the first wear-resistant layer 21 on the first side surface 113 is smaller than the area of the first side surface 113, and the first wear-resistant layer 21 has a certain coverage area on the inner surface 111 and / or the first surface 112.
[0057] Specifically, the first wear-resistant layer 21 is transparent. The first wear-resistant layer 21 is hydrophobic. In one embodiment, the first wear-resistant layer 21 comprises a fluorosilane. In another embodiment, the first wear-resistant layer 21 comprises a fluoroether silane. The roughness Ra1 of the first wear-resistant layer 21 is in the range of: Ra1 ≤ 0.5 μm. In one embodiment, the roughness Ra1 of the first wear-resistant layer 21 is in the range of: Ra1 ≤ 0.1 μm. The pencil hardness HB1 of the first wear-resistant layer 21 is in the range of: HB1 ≥ 7H. In one embodiment, the pencil hardness HB1 of the first wear-resistant layer 21 is in the range of: HB1 ≥ 9H. The surface energy G1 of the first wear-resistant layer 21 is in the range of: G1 ≤ 30 dyn.
[0058] It is understood that the first wear-resistant layer 21 includes fluorosilane, which can be either a fluorosilane coating formed on the surface of the first wear-resistant layer 21 or the main material of the first wear-resistant layer 21 contains fluorosilane. The first wear-resistant layer 21 also includes fluoroether silane, which can be either a fluoroether silane coating formed on the surface of the first wear-resistant layer 21 or the main material of the first wear-resistant layer 21 contains fluoroether silane. In this embodiment, the first wear-resistant layer 21 is a layer of unequal thickness, and the maximum thickness t1 of the first wear-resistant layer 21... max The range is: t1 max ≥2μm. In one embodiment, the maximum thickness t1 of the first wear-resistant layer 21 is... max The range is: t1 max≥5μm. The tolerance of the thickness t1 of the first wear-resistant layer 21 is ±1μm. In one embodiment, the tolerance of the thickness t1 of the first wear-resistant layer 21 is ±0.5μm.
[0059] In other embodiments, the first wear-resistant layer 21 is a layer of uniform thickness, and the thickness t1 of the first wear-resistant layer 21 ranges from t1 ≥ 2 μm. In one embodiment, the thickness t1 of the first wear-resistant layer 21 ranges from t1 ≥ 5 μm. The tolerance of the thickness t1 of the first wear-resistant layer 21 is ±1 μm. In another embodiment, the tolerance of the thickness t1 of the first wear-resistant layer 21 is ±0.5 μm.
[0060] It should be noted that the first wear-resistant layer 21 in this embodiment is formed by: pre-treating the first side surface 113, including wiping with alcohol, and then performing plasma or flame treatment; the first wear-resistant layer 21 is formed by spraying combined with thermosetting process. In one embodiment, after pre-treating the first side surface 113, the surface energy G of the first side surface 113 is... 113 ≥42 dyn; In another embodiment, after pretreatment of the first side surface 113, the surface energy G of the first side surface 113 is... 113 ≥50 dyn. In other embodiments, the first wear-resistant layer 21 may also be formed by other methods such as vapor deposition. This application does not limit the formation method of the first wear-resistant layer 21.
[0061] It is understandable that after the first side surface 113 is pretreated, the first side surface 113 has a large surface energy, which can make the first wear-resistant layer 21 have better wettability on the first side surface 113, which is beneficial to the formation of the first wear-resistant layer 21 on the first side surface 113.
[0062] Please see Figure 5 In this embodiment, to ensure the sealing of the frameless door 300 to the vehicle 1000, when the frameless door 300 is closed and the window glass 10 is rising, the first wear-resistant layer 21 of the first side 113 of the window glass 10 will slide along the first sealing strip 500 and deform the first sealing strip 500. When the window 100 is completely closed, the inner surface 111 of the window glass 10 is tightly attached to the first sealing strip 500.
[0063] It is understood that in this embodiment, a first wear-resistant layer 21 is provided on the first side 113, and the first wear-resistant layer 21 covers the first friction area 1131. The first wear-resistant layer 21 has a smooth surface. When the first wear-resistant layer 21 slides along the first sealing strip 500 and deforms the first sealing strip 500 by squeezing it, the friction between the first wear-resistant layer 21 and the first sealing strip 500 is small, and the wear of the first wear-resistant layer 21 on the first sealing strip 500 is small. Therefore, the service life of the first sealing strip 500 can be extended, avoiding frequent replacement of the first sealing strip 500 and reducing costs. The small wear of the first sealing strip 500 can ensure the airtightness of the frameless door 300 to the vehicle 1000, preventing adverse effects such as water seepage between the top of the frameless door 300 and the body 400; it can also ensure that the noise, vibration, and harshness (NVH) performance of the vehicle 1000 meets the usage requirements. The small wear of the first sealing strip 500 can also prevent the first sealing strip 500 from producing abnormal noise after rapid aging.
[0064] Compared to existing technologies, which improve the lifting mechanism to allow the window glass 10 of the frameless door 300 to rise to the first sealing strip 500 before fitting with it, this embodiment of the application has a simpler process, eliminating the need for a complex lifting mechanism and reducing costs. Furthermore, compared to existing technologies that further process the first side surface 113 of the window glass 10 by changing the friction head of the edging machine to reduce its roughness, or that perform surface treatment on the first sealing strip 500 to improve its wear resistance, this embodiment of the application has higher processing efficiency and significantly better results.
[0065] Furthermore, by ensuring that the first wear-resistant layer 21 covers 100% of the area of the first side 113, i.e., the first wear-resistant layer 21 completely covers the first side 113, color differences at different locations of the first side 113 can be avoided when viewing the window 10 from the outside of the window 10 at a position opposite to the first side 113. Therefore, the aesthetics of the window 10 can be improved.
[0066] By making the first wear-resistant layer 21 hydrophobic, the waterproof effect of the frameless door 300 can be improved, preventing water droplets from the outside of the vehicle 1000 from adhering to the first wear-resistant layer 21. This, in turn, prevents water droplets from entering the interior of the vehicle 1000 along the space between the first wear-resistant layer 21 and the first sealing strip 500 during the raising and lowering of the window 100 of the frameless door 300. Controlling the roughness Ra1 of the first wear-resistant layer 21 to ≤0.5μm ensures a smooth surface, preventing damage to the first sealing strip 500 when it slides along it. Controlling the pencil hardness HB1 of the first wear-resistant layer 21 to ≥7H improves its wear resistance, preventing damage after repeated friction with the first sealing strip 500 and ensuring its long-term use.
[0067] Please see Figure 6 This application provides a second embodiment of a vehicle window. The distinguishing feature of this embodiment compared to the first embodiment is that the vehicle window 100 further includes a second wear-resistant layer 22. The second wear-resistant layer 22 is elongated and extends along the height direction of the window glass 10. The second wear-resistant layer 22 covers the second friction area 1141 and encloses multiple protrusions of the second friction area 1141. The coverage area of the second wear-resistant layer 22 on the second side surface 114 is at least 10% of the area of the second side surface 114, specifically 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, etc. It is understood that "coverage" includes complete coverage and partial coverage.
[0068] In this embodiment, for example, the second side 114 is semi-circular in shape, and the second wear-resistant layer 22 is C-shaped.
[0069] In this embodiment, preferably, the second wear-resistant layer 22 covers 30%-100% of the area of the second side surface 114. Please refer to the following reference. Figure 2 , Figure 6 and Figure 7 Along the thickness direction of the window glass 100, the second wear-resistant layer 22 extends from the second junction (not shown) between the inner surface 111 and the second side surface 114 in a direction away from the second junction.
[0070] In one implementation, such as Figure 6 The second wear-resistant layer 22 covers 50% of the area of the second side 114.
[0071] In another implementation, please refer to Figure 7 The second wear-resistant layer 22 covers 100% of the area of the second side 114.
[0072] In other embodiments, the second wear-resistant layer 22 may also completely cover the second side surface 114 and partially cover the inner surface 111 and / or the first surface 112. In this case, the coverage area of the second wear-resistant layer 22 on the second side surface 114 accounts for 100% of the area of the second side surface 114, and the second wear-resistant layer 22 has a certain coverage area on the inner surface 111 and / or the first surface 112.
[0073] In other embodiments, the second wear-resistant layer 22 may also partially cover the second side surface 114 and partially cover the inner surface 111. In this case, the coverage area of the second wear-resistant layer 22 on the second side surface 114 is smaller than the area of the second side surface 114, and the second wear-resistant layer 22 has a certain coverage area on the inner surface 111 and / or the first surface 112.
[0074] It should be noted that one end of the second wear-resistant layer 22 along the height direction can be connected to one end of the first wear-resistant layer 21 along the length direction, or it can be spaced apart from one end of the first wear-resistant layer 21 along the length direction.
[0075] Specifically, the second wear-resistant layer 22 is transparent. The second wear-resistant layer 22 is hydrophobic. In one embodiment, the second wear-resistant layer 22 comprises a fluorosilane. In another embodiment, the second wear-resistant layer 22 comprises a fluoroether silane. The roughness Ra2 of the second wear-resistant layer 22 is in the range of: Ra2 ≤ 0.5 μm. In one embodiment, the roughness Ra2 of the second wear-resistant layer 22 is in the range of: Ra2 ≤ 0.1 μm. The pencil hardness HB2 of the second wear-resistant layer 22 is in the range of: HB2 ≥ 7H. In one embodiment, the pencil hardness HB2 of the second wear-resistant layer 22 is in the range of: HB2 ≥ 9H. The surface energy G2 of the second wear-resistant layer 22 is in the range of: G2 ≤ 30 dyn.
[0076] It is understood that the second wear-resistant layer 22 includes fluorosilanes, which can be either a fluorosilane coating formed on the surface of the second wear-resistant layer 22 or the main material of the second wear-resistant layer 22 contains fluorosilanes. Alternatively, the second wear-resistant layer 22 may include fluoroether silanes, which can be either a fluoroether silane coating formed on the surface of the second wear-resistant layer 22 or the main material of the second wear-resistant layer 22 contains fluoroether silanes.
[0077] In this embodiment, the second wear-resistant layer 22 is a layer of unequal thickness, and the maximum thickness t2 of the first wear-resistant layer 21 is... max The range is: t2 max ≥2μm. In one embodiment, the maximum thickness t2 of the second wear-resistant layer 22 is... max The range is: t2 max ≥5μm. The tolerance of the thickness t2 of the second wear-resistant layer 22 is ±1μm. In one embodiment, the tolerance of the thickness t2 of the second wear-resistant layer 22 is ±0.5μm.
[0078] In other embodiments, the second wear-resistant layer 22 is a layer of uniform thickness, and the thickness t2 of the second wear-resistant layer 22 ranges from t2 ≥ 2 μm. In one embodiment, the thickness t2 of the second wear-resistant layer 22 ranges from t2 ≥ 5 μm. The tolerance of the thickness t2 of the second wear-resistant layer 22 is ±1 μm. In another embodiment, the tolerance of the thickness t2 of the second wear-resistant layer 22 is ±0.5 μm.
[0079] It should be noted that the second wear-resistant layer 22 in this embodiment is formed by: pre-treating the second side surface 114, including wiping with alcohol, and then performing plasma or flame treatment; and forming the second wear-resistant layer 22 using a spraying combined with thermosetting process. In one embodiment, after pre-treating the second side surface 114, the surface energy G of the second side surface 114 is... 114 ≥42 dyn; In another embodiment, after pretreatment of the second side surface 114, the surface energy G of the second side surface 114 is... 114 ≥50 dyn. In other embodiments, the second wear-resistant layer 22 may also be formed by other methods such as vapor deposition. This application does not limit the formation method of the second wear-resistant layer 22.
[0080] It is understandable that after the second side 114 is pretreated, the second side 114 has a large surface energy, which can make the second wear-resistant layer 22 have better wettability on the second side 114, which is beneficial to the formation of the second wear-resistant layer 22 on the second side 114.
[0081] Understandably, when the frameless door 300 is closed, during the raising and lowering of the window 100, the second friction area 1141 of the second side surface 114 of the window glass 10 rubs against the second sealing strip. By providing a second wear-resistant layer 22 on the second side surface 114, the second wear-resistant layer 22 covers the second friction area 1141. The second wear-resistant layer 22 has a smooth surface, which reduces the friction between the second wear-resistant layer 22 and the second sealing strip, thereby reducing the wear of the second sealing strip by the window glass 10, extending the service life of the second sealing strip, avoiding frequent replacement of the second sealing strip, and reducing costs. In addition, less wear on the second sealing strip can also ensure the airtightness of the frameless door 300, preventing adverse effects such as water seepage between the side of the frameless door 300 and the body 400.
[0082] By making the second wear-resistant layer 22 hydrophobic, the waterproof effect of the frameless door 300 can be improved, preventing water droplets from the outside of the vehicle 1000 from adhering to the second wear-resistant layer 22. This, in turn, prevents water droplets from entering the interior of the vehicle 1000 along the space between the second wear-resistant layer 22 and the second sealing strip during the raising and lowering of the window 100 of the frameless door 300. Controlling the roughness Ra2 of the second wear-resistant layer 22 to ≤0.5μm ensures a smooth surface, preventing damage to the second sealing strip when it slides along it. Controlling the pencil hardness HB2 of the second wear-resistant layer 22 to ≥7H improves its wear resistance, preventing damage after repeated friction with the second sealing strip and ensuring its long-term use.
[0083] Please see Figure 8 This application provides a third embodiment of a vehicle window. The distinguishing feature of this embodiment compared to any of the above embodiments is that the vehicle window 100 further includes a third wear-resistant layer 23. The third wear-resistant layer 23 is elongated and extends along the height direction of the window glass 10. The third wear-resistant layer 23 covers the third friction area 1151 and encloses multiple protrusions of the third friction area 1151. The coverage area of the third wear-resistant layer 23 on the third side surface 115 is at least 10% of the area of the third side surface 115, specifically 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, etc. It is understood that "coverage" includes complete coverage and partial coverage.
[0084] In this embodiment, for example, the third side 115 is semi-circular in shape, and the third wear-resistant layer 23 is C-shaped.
[0085] In this embodiment, preferably, the coverage area of the third wear-resistant layer 23 on the third side surface 115 accounts for 30%-100% of the area of the third side surface 115. Please refer to the following reference. Figure 2 , Figure 8 and Figure 9 Along the thickness direction of the window glass 100, the third wear-resistant layer 23 extends from the third junction (not shown in the figure) between the inner surface 111 and the third side surface 115 in a direction away from the third junction.
[0086] In one implementation, such as Figure 8 The third wear-resistant layer 23 covers 50% of the area of the third side 115.
[0087] In another implementation, please refer to Figure 9 The third wear-resistant layer 23 covers 100% of the area of the third side 115.
[0088] In other embodiments, the third wear-resistant layer 23 may also completely cover the third side surface 115 and partially cover the inner surface 111 and / or the first surface 112. In this case, the coverage area of the third wear-resistant layer 23 on the third side surface 115 accounts for 100% of the area of the third side surface 115, and the third wear-resistant layer 23 has a certain coverage area on the inner surface 111 and / or the first surface 112.
[0089] In other embodiments, the third wear-resistant layer 23 may also partially cover the third side surface 115 and partially cover the inner surface 111. In this case, the coverage area of the third wear-resistant layer 23 on the third side surface 115 is smaller than the area of the third side surface 115, and the third wear-resistant layer 23 has a certain coverage area on the inner surface 111 and / or the first surface 112.
[0090] It should be noted that one end of the third wear-resistant layer 23 along the height direction can be connected to one end of the first wear-resistant layer 21 along the length direction, or it can be spaced apart from one end of the first wear-resistant layer 21 along the length direction.
[0091] Specifically, the third wear-resistant layer 23 is transparent. The third wear-resistant layer 23 is hydrophobic. In one embodiment, the third wear-resistant layer 23 comprises a fluorosilane. In another embodiment, the third wear-resistant layer 23 comprises a fluoroether silane. The roughness Ra3 of the third wear-resistant layer 23 is in the range of: Ra3 ≤ 0.5 μm. In one embodiment, the roughness Ra3 of the third wear-resistant layer 23 is in the range of: Ra3 ≤ 0.1 μm. The pencil hardness HB3 of the third wear-resistant layer 23 is in the range of: HB3 ≥ 7H. In one embodiment, the pencil hardness HB3 of the third wear-resistant layer 23 is in the range of: HB3 ≥ 9H. The surface energy G3 of the third wear-resistant layer 23 is in the range of: G3 ≤ 30 dyn.
[0092] It is understood that the third wear-resistant layer 23 includes fluorosilane, which can be either a fluorosilane coating formed on the surface of the third wear-resistant layer 23 or the main material of the third wear-resistant layer 23 contains fluorosilane. Alternatively, the third wear-resistant layer 23 may include fluoroether silane, which can be either a fluoroether silane coating formed on the surface of the third wear-resistant layer 23 or the main material of the third wear-resistant layer 23 contains fluoroether silane.
[0093] In this embodiment, the third wear-resistant layer 23 is a layer of unequal thickness, and the maximum thickness of the third wear-resistant layer 23 is t3. max The range is: t3 max ≥2μm. In one embodiment, the maximum thickness t3 of the third wear-resistant layer 23 is... max The range is: t3 max ≥5μm. The tolerance of the thickness t3 of the third wear-resistant layer 23 is ±1μm. In one embodiment, the tolerance of the thickness t3 of the third wear-resistant layer 23 is ±0.5μm.
[0094] In other embodiments, the third wear-resistant layer 23 is a layer of uniform thickness, and the thickness t3 of the third wear-resistant layer 23 ranges from t3 ≥ 2 μm. In one embodiment, the thickness t3 of the third wear-resistant layer 23 ranges from t3 ≥ 5 μm. The tolerance of the thickness t3 of the third wear-resistant layer 23 is ±1 μm. In another embodiment, the tolerance of the thickness t3 of the third wear-resistant layer 23 is ±0.5 μm.
[0095] It should be noted that the third wear-resistant layer 23 in this embodiment is formed by: pre-treating the third side surface 115, including wiping with alcohol, and then performing plasma or flame treatment; the third wear-resistant layer 23 is formed by spraying combined with thermosetting process. In one embodiment, after pre-treating the third side surface 115, the surface energy G of the third side surface 115 is... 115 ≥42 dyn; In another embodiment, after pretreatment of the third side surface 115, the surface energy G of the third side surface 115 is... 115 ≥50 dyn. In other embodiments, the first wear-resistant layer 21 may also be formed by other methods such as vapor deposition. This application does not limit the formation method of the first wear-resistant layer 21.
[0096] It is understandable that after the third side 115 is pretreated, the third side 115 has a large surface energy, which can make the third wear-resistant layer 23 have better wettability on the third side 115, which is beneficial to the formation of the third wear-resistant layer 23 on the third side 115.
[0097] It is understandable that when the frameless door 300 is closed, during the raising and lowering of the window 100, the third friction area 1151 of the third side 115 of the window glass 10 rubs against the third sealing strip. By setting a third wear-resistant layer 23 in the third friction area 1151 of the third side 115, the third wear-resistant layer 23 covers the third friction area 1151. The third wear-resistant layer 23 has a smooth surface, which can also extend the service life of the third sealing strip and ensure the airtightness of the frameless door 300 to the vehicle 1000.
[0098] By making the third wear-resistant layer 23 hydrophobic, the waterproof effect of the frameless door 300 can be improved, preventing water droplets from the exterior of the vehicle 1000 from adhering to the third wear-resistant layer 23. This, in turn, prevents water droplets from entering the interior of the vehicle 1000 along the space between the third wear-resistant layer 23 and the third sealing strip during the raising and lowering of the window 100 of the frameless door 300. Controlling the roughness Ra3 of the third wear-resistant layer 23 to ≤0.5μm ensures a smooth surface, preventing damage to the third sealing strip when it slides along it. Controlling the pencil hardness HB3 of the third wear-resistant layer 23 to ≥7H improves its wear resistance, preventing damage after repeated friction with the third sealing strip and ensuring its long-term use.
[0099] Please see Figure 10 This application provides a fourth embodiment of the window 100 of a frameless car door 300. The distinguishing feature of this embodiment compared to any of the above embodiments is that the window 100 further includes a functional layer 30.
[0100] The functional layer 30 covers the inner surface 111 of the window glass 10. Specifically, the functions of the functional layer 30 include, but are not limited to, UV protection, infrared protection, and conductivity. For example, the main material of the functional layer 30 is silica sol, to which materials capable of absorbing UV and infrared rays are added. The thickness of the functional layer 30 is 5.0 μm (with certain dimensional tolerances allowed).
[0101] It should be noted that the functional layer 30 in this embodiment is formed by pretreating the inner surface 111, including wiping with alcohol, followed by plasma or flame treatment; and then forming the functional layer 30 using a spraying combined with thermosetting process. In other embodiments, the functional layer 30 may also be formed by other methods such as vapor deposition. This embodiment does not limit the formation method of the functional layer 30.
[0102] In one embodiment, the functional layer 30 is connected to the first wear-resistant layer 21. Specifically, one side of the functional layer 30 along the height direction is connected to one side of the first wear-resistant layer 21 along the width direction. It can be understood that during the process of forming the functional layer 30 on the inner surface 111 of the window glass 10, the first wear-resistant layer 21 can be formed simultaneously on the side of the window glass 10.
[0103] It is understandable that by forming a functional layer 30 on the inner surface 111 of the window glass 10, the functions of the vehicle 1000 can be made more diverse, thereby improving the customer's user experience. Furthermore, the cost is lower compared to applying an additional functional film to the inner surface 111 of the window glass 10. In this embodiment, the first wear-resistant layer 21 can be formed during the formation process of the functional layer 30, thus simplifying the preparation process of the first wear-resistant layer 21 and reducing labor and time costs.
[0104] Please see Figure 11 This application provides a fifth embodiment of the window 100 of a frameless car door 300. The distinguishing feature of this embodiment compared to any of the above embodiments is that the window glass 10 further includes a second glass panel 12 and an intermediate layer 13. The second glass panel 12 includes an outer surface 121 and a second surface 122. Along the thickness direction of the window glass 10, the first glass panel 11, the intermediate layer 13, and the second glass panel 12 are sequentially stacked. The first surface 112 of the first glass panel 11 faces the intermediate layer 13. The second surface 122 of the second glass panel 12 faces the intermediate layer 13.
[0105] In one embodiment, at least one side of the second glass plate 12 is provided with a wear-resistant layer.
[0106] It is understood that in this embodiment, the window glass 10 is laminated glass, which ensures the strength of the window glass 10. By providing a wear-resistant layer on the side of the first glass plate 11 of the window glass 10, the wear of the sealing strip connected to the vehicle body 400 can be reduced, the service life of the sealing strip can be extended, and the sealing performance of the vehicle 1000 can be guaranteed.
[0107] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
