[Technical Field]
[0001] REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202111145784.3, filed on September 28, 2021, entitled "Vehicle Window Assembly and Vehicle," the entire contents of which are incorporated herein by reference.
[0002] FIELD OF THE INVENTION This application relates to the technical field of vehicle component manufacturing, and more particularly to vehicle window assemblies and vehicles. [Background technology]
[0003] Vehicles have traditionally been one of the most important means of transportation for people, and front windshields that integrate Advanced Driving Assistance Systems (ADAS) are one of the important research directions for improving the driving experience of vehicles.
[0004] Currently, most ADAS functional assemblies are integrated into the interior side of the front windshield, and an increasing number of additional functions are being integrated into the front windshield, such as thermal insulation, UV protection, electric heating, and the addition of shade bands, which impact the functionality of the ADAS functional assemblies. Adaptively designing only the ADAS area of the front windshield requires highly complex processes. Another method for integrating the ADAS functional assemblies is to splice a plastic block to the outside of the front windshield, but this results in uneven outer surfaces and weak overall strength. Furthermore, front windshields with integrated ADAS have high localized optical requirements for the ADAS area. Meeting these high localized optical requirements increases the difficulty of molding the entire front windshield, resulting in lower yields and higher costs. Summary of the Invention

[0028] Hereinafter, the technical solutions of the embodiments of the present application will be clearly and comprehensively described with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments that can be obtained by those skilled in the art without creative efforts are all within the scope of protection of the present application.
[0029] The present application provides a vehicle window assembly 1. Referring to FIGS. 1 and 2 together, FIG. 1 is a top view of a vehicle window assembly according to an embodiment of the present application. FIG. 2 is a cross-sectional view taken along line II in FIG. 1. The vehicle window assembly 1 includes a laminated glass 11, a fixing member 12, and a connecting member 13. The laminated glass 11 has a main line of sight direction as a main field of view of the vehicle window assembly 1. The fixing member 12 is integrally formed and includes a plurality of fixing grooves 121 spaced apart from each other. The opening direction of the fixing grooves 121 is opposite to the main field of view direction, and the plurality of fixing grooves 121 are used to fixedly attach a plurality of functional assemblies 14, respectively. The wavelength range of signals transmitted and / or received by the functional assemblies 14 is 380 nm to 1650 nm, and the connecting member 13 connects the laminated glass 11 and the fixing member 12.
[0030] In this embodiment, also refer to Figure 3, which is a local cross-sectional view taken along line II-II in Figure 1. The laminated glass 11 comprises at least one thermoplastic interlayer 111, a first transparent sheet 112, and a second transparent sheet 113. The first transparent sheet 112 has a first major surface 1121, a first top side 1122, and a second major surface 1123. The second transparent sheet 113 has a third major surface 1131, a second top side 1132, and a fourth major surface 1133. The thermoplastic interlayer 111 has a second major surface 1123 and a third major surface 1134. 4 The main surface of 1133 The fixing member 12 has an outer surface and an inner surface, the outer surface of the fixing member 12 is flush with the first major surface 1121, and the fixing member 12 is fixedly connected to the first top side surface 1122 and the second top side surface 1132.
[0031] The laminated glass 11 has a wavelength range of 380 nm to 780 nm. Against the light within The fixing member 12 has a transmittance of at least 70%. The fixing member 12 has a transmittance of at least 92% for signals in the wavelength range of 380 nm to 1650 nm that are incident at an incident angle of 0°.
[0032] Specifically, the vehicle window assembly 1 is applied to a vehicle, and the vehicle window assembly 1 typically has a main viewing portion through which a vehicle occupant primarily observes the situation outside the vehicle window assembly 1. The main viewing direction is the line of sight in which the vehicle occupant observes the outside of the vehicle through the vehicle window assembly 1, as shown by the arrow in FIG.
[0033] In this embodiment, the laminated glass 11 is a glass having a wavelength range of 380 nm to 780 nm as the main field of view of the vehicle window assembly 1. Against the light withinThe first transparent plate 112 and the second transparent plate 113 have a transmittance of at least 70%, i.e., a visible light transmittance of 70% or more, thereby ensuring driving safety. The first transparent plate 112 and the second transparent plate 113 may be made of inorganic glass such as soda-lime-silica glass, aluminosilicate glass, lithium aluminum silicate (LAS) glass, or borosilicate glass, or may be made of organic glass such as polycarbonate (PC) glass or polymethyl methacrylate (PMMA) glass. The thermoplastic interlayer 111 may be at least one selected from polyvinyl chloride (PVC), polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyacrylate (PA), ionic interlayer (SentryGlas® Plus (SGP)), polyurethane (PU), etc. The thermoplastic interlayer 111 may have a single-layer structure or a multi-layer structure, and examples of the multi-layer structure include a two-layer structure, a three-layer structure, a four-layer structure, and a five-layer structure. A fixing member 12 for mounting and attaching a functional assembly 14 is provided on the upper part of the laminated glass 11 via a connecting member 13. The fixing member 12 is formed by an injection process or a mold press process using a resin or a resin-based composite material.This significantly improves the surface matching accuracy, eliminates the need for the laminated glass 11 to consider the performance requirements of the functional assembly 14, and maintains the integrity of the laminated glass 11. This significantly improves the manufacturing efficiency of the laminated glass 11, and also enables more complex needs such as thermal insulation, UV protection, electric heating, sound insulation, and the addition of shade bands to be realized at a lower cost. At the same time, the functional assembly can function better and be separated from the laminated glass to prevent interference with each other.
[0034] Furthermore, the laminated glass 11 is resistant to light in the wavelength range of 780 nm to 2500 nm. Against the light within The transmittance is 30% or less, thereby satisfying the heat insulation requirement. Specifically, a tinted thermoplastic resin interlayer 111, a tinted first transparent plate 112, and / or a tinted second transparent plate 113 can be used, and the second main surface 1123 of the first transparent plate 112 and the second main surface 1124 of the second transparent plate 113 can be used. 4 The main surface of 1133 A heat insulating assembly may be provided between the first transparent plate 112 and the second transparent plate 113. Examples of the heat insulating assembly include a heat insulating coating that can absorb infrared rays, a heat insulating coating film that can reflect infrared rays, etc. 4 The main surface of 1133 An electric heating assembly, a sound insulation assembly, a head-up display assembly, etc. can be installed between the two, thereby meeting the needs of defrosting / defogging, sound insulation, head-up display, etc.
[0035] The fixing member 12 can be integrally formed by an injection or extrusion process. As can be seen, the integral formation of the fixing member 12 results in a relatively flat outer surface, which is beneficial to the stability of the wiper strip. Furthermore, the fixing member 12 is made of a transparent material such as non-glass, which effectively improves the strength of the fixing member 12 and solves the technical problem of insufficient strength when the fixing member 12 is made of a transparent material such as single-pane glass. In this embodiment, the strength of the fixing member 12 is equivalent to the strength of tempered glass specified in the Chinese national standard, i.e., the strength required for the fixing member 12 to withstand an impact from a 227g steel ball dropped from an impact height of 2.5m.
[0036] In addition, the fixing member 12 has higher assembly elasticity and shape plasticity, which solves the process problems of the inconsistency between thickness and strength within a certain thickness range of the conventional transparent substrate and the difficulty in aligning the splicing surface of the rigid transparent glass plate with the splicing surface of the rigid transparent glass plate. It can be understood that in other possible embodiments, the fixing member 12 may be integrally formed by other processes, and the present application is not limited thereto.
[0037] Specifically, the opening diameter of the fixing groove 121 may be different to accommodate different functional assemblies 14. The functional assembly 14 can emit or receive electromagnetic signals. For example, if the functional assembly 14 is a laser radar, it can emit and receive near-infrared signals with a wavelength of 800 nm to 1600 nm. At the correct installation angle, if the laser radar emits a laser with a wavelength of 905 nm or 1550 nm, the signal transmittance can be 85% or more. If the functional assembly 14 is a camera, it can receive visible light (with a wavelength of 380 nm to 780 nm) or near-infrared signals (with a wavelength of 780 nm to 1400 nm). As can be understood, typically, the direction in which the functional assembly 14 emits electromagnetic signals is approximately the same as the main viewing direction, and the direction in which the functional assembly 14 receives electromagnetic signals is approximately opposite to the main viewing direction.
[0038] As can be seen, in this embodiment, the signal transmission direction of the functional assembly 14 is approximately the same as or opposite to the main viewing direction. Therefore, the fastening groove 121 is not only used to securely mount the functional assembly 14, but also serves to securely mount the functional assembly 14. In the main viewing direction, the thickness of the fastening member 12 with the fastening groove 121 is smaller than the thickness of the fastening member 12 without the fastening groove 121. Therefore, when the functional assembly 14 fixed in the fastening groove 121 transmits or receives an electromagnetic signal, the transmission or reception via the fastening groove 121 can improve the signal transmittance. Furthermore, the reduced thickness facilitates the installation and positioning of the functional assembly. At the same time, the fastening member 12 is integrally molded, has a flat surface, and is connected to the laminated glass 11 by the connecting member 13, resulting in high overall strength and low process complexity.
[0039] In one possible embodiment, since the fixing member 12 is made of a transparent material such as non-glass, infrared auxiliary agents and additives are added during the manufacturing of a resin plate such as PC or PMMA, so that the fixing member 12 has high infrared light transmittance, similar to panels with high infrared light transmittance such as SABIC PC (121R-21051), COVESTRO PC (2405-450601), and HY700H-HG PMMA. As can be seen, in this embodiment, assuming that the fixing member 12 is made thinner, a process for improving signal transmittance can be easily realized, allowing the fixing member 12 to simultaneously have higher transmittance, thinner thickness, and good strength.
[0040] In this embodiment, the fixing member 12 further includes at least one protrusion. The protrusion extends from a side of the fixing member 12 that is closest to the laminated glass 11. For example, referring back to FIG. 3 , the first protrusion 124 is provided corresponding to the thermoplastic intermediate layer 111 so as to accommodate the gap between the first transparent sheet 112 and the second transparent sheet 113. As can be seen, the surface shapes of the laminated glass 11 and the fixing member 12 correspond to each other at adjacent locations, allowing the connecting member 13 to better connect the laminated glass 11 and the fixing member 12, thereby further improving the connection strength between the laminated glass 11 and the fixing member 12.
[0041] Specifically, in order to provide a space for the connecting member 13 and to prevent the first protrusion 124 from contacting the laminated glass 11, the protrusion length of the first protrusion 124 in the direction perpendicular to the main viewing direction is 0.5 mm or less. Preferably, the protrusion length of the first protrusion 124 in the direction perpendicular to the main viewing direction is 0.4 mm or less. Specifically, the protrusion length of the first protrusion 124 in the direction perpendicular to the main viewing direction may be 0.37 mm, 0.35 mm, or 0.30 mm, and is not limited thereto in the present application.
[0042] In one possible embodiment, referring also to Figure 4, Figure 4 is a partial cross-sectional view of a vehicle window assembly according to an embodiment of the present application. The fixing member 12 includes a main body 122 and an extension 123 extending from the main body 122. The fixing groove 121 is provided in the main body 122, and the extension 123 and the laminated glass 11 are arranged to at least partially overlap. The ratio of the length H of the overlapping portion between the extension 123 and the laminated glass 11 to the length L of the main body 122 in a direction perpendicular to the main viewing direction is in the range of 0.1 to 1.
[0043] Specifically, the extension 123 increases the contact area between the fixing member 12 and the laminated glass 11. As can be seen, in this embodiment, the extension 123 enables the connecting member 13 to better connect the laminated glass 11 and the fixing member 12, thereby improving the connection strength between the laminated glass 11 and the fixing member 12.
[0044] In this embodiment, the ratio of the length H of the overlapping portion between the extension portion 123 and the laminated glass 11 to the length L of the main body 122 in the direction perpendicular to the main viewing direction is in the range of 0.1 to 1. Preferably, the ratio of the length H of the overlapping portion between the extension portion 123 and the laminated glass 11 to the length L of the main body 122 in the direction perpendicular to the main viewing direction can be in the range of 0.4 to 0.7. Specifically, the ratio of the length H of the overlapping portion between the extension portion 123 and the laminated glass 11 to the length L of the main body 122 in the direction perpendicular to the main viewing direction can be 0.45, 0.56, 0.63, etc., and is not limited thereto in the present application.
[0045] In one possible embodiment, referring to Figures 3 and 4 together, in a direction perpendicular to the main viewing direction, the first top side 1122 and the second top side 1132 are approximately coplanar, and specifically, depending on the tolerances in the manufacturing process, the height difference between the first top side 1122 and the second top side 1132 in the direction perpendicular to the main viewing direction is less than 2 mm.
[0046] 5 to 9 , in another possible embodiment, the height difference between the first top side surface 1122 and the second top side surface 1132 in the direction perpendicular to the main viewing direction is 2 mm or more, thereby further improving the connection strength between the laminated glass 11 and the fixing member 12. More preferably, the height difference is 5 mm or more. Considering the integrity of the laminated glass, the height difference is even more preferably 50 mm or less, and even more preferably 20 mm or less. Here, the height difference may be the portion where the first top side surface 1122 is higher than the second top side surface 1132, or the portion where the second top side surface 1132 is higher than the first top side surface 1122.
[0047] In this embodiment, the fixing member 12 further includes a second protrusion 125. The second protrusion 125 extends from a side of the fixing member 12 closer to the laminated glass 11 and corresponds to a side of the first transparent plate 112 or a side of the second transparent plate 113.
[0048] Specifically, this embodiment is similar to the above-described embodiment in the following respects: The surface shapes of the laminated glass 11 and the fixing member 12 correspond to each other at adjacent locations, thereby enabling the connecting member 13 to better connect the laminated glass 11 and the fixing member 12.
[0049] As can be seen, this embodiment differs from the above-described embodiments in the following respects: As shown in Fig. 5, the second protrusion 125 corresponds to the side surface of the first transparent plate 112 or the side surface of the second transparent plate 113, and therefore the shape of the second protrusion 125 corresponds to the outer edge of the first transparent plate 112 or the outer edge of the second transparent plate 113. That is, the outer surface of the second protrusion 125 is flush with the outer surface of the first transparent plate 112 or the outer surface of the second transparent plate 113, the inner surface of the second protrusion 125 corresponds to (i.e., fits) a portion of the outer edge of the first transparent plate 112 or a portion of the outer edge of the second transparent plate 113, and the inner surface of the second protrusion 125 and a portion of the outer edge of the first transparent plate 112 or a portion of the outer edge of the second transparent plate 113 have similar smooth shapes. As can be seen, this configuration further improves the connection strength between the laminated glass 11 and the fixing member 12, while at the same time ensuring a smooth transition from the outer surface of the laminated glass 11 to the outer surface of the fixing member 12, thereby ensuring that the entire surface of the vehicle window assembly 1 is flat.
[0050] As can be understood, in this embodiment, the length of the second protrusion 125 in the direction perpendicular to the main viewing direction is not limited in this application, as long as the second protrusion 125 avoids damaging the laminated glass 11.
[0051] Next, the fixed connection between the extension 123 and the second main surface 1123, the third main surface 1131 or the fourth main surface 1133, respectively, will be described in detail.
[0052] 3 to 6, in one possible embodiment, Fig. 6 is a cross-sectional view of a portion of a vehicle window assembly according to another embodiment of the present application. The connecting member 13 includes a first joint portion 131 and a second joint portion 132. The first joint portion 131 is provided on a side surface of the first transparent plate 112 or a side surface of the second transparent plate 113. The second joint portion 132 is integrally formed with the fixing member 12. The first joint portion 131 and the second joint portion 132 cooperate to fix the laminated glass 11 and the fixing member 12 together.
[0053] Specifically, the first joint 131 and the second joint 132 are a corresponding combination. For example, if the first joint 131 is a slot, the second joint 132 is a buckle, which is fitted into the first joint 131 and snapped onto the first joint 131 to be fixed. As another example, if the first joint 131 is a magnetic element, the second joint 132 is a magnetic material, and when the second joint 132 and the first joint 131 come into contact with each other, a magnetic attraction force is generated between the first joint 131 and the second joint 132, thereby fixing the first joint 131 to the second joint 132. As another example, if the first joint 131 is an adhesive, the second joint 132 can be an adhesive member, and when the second joint 132 and the first joint 131 come into contact with each other, an adhesive force is generated between the first joint 131 and the second joint 132, thereby fixing the first joint 131 to the second joint 132. As can be understood, the corresponding combination of the first joint 131 and the second joint 132 is not limited in the present application.
[0054] In one possible embodiment, referring also to FIG. 7, FIG. 7 is a partial cross-sectional view of a vehicle window assembly 1 according to yet another embodiment of the present application. Specifically, in this embodiment, as shown in FIG. 7, the first transparent sheet 112 is higher than the second transparent sheet 113 in a direction perpendicular to the primary viewing direction. The first joint 131 is provided on a side of the first transparent sheet 112 that is closer to the second transparent sheet 113. The connecting member 13 further includes a third joint 133 and a fourth joint 134. The third joint 133 is provided on a side of the second transparent sheet 113 that is farther from the first transparent sheet 112, and the fourth joint 134 extends from the fixing member 12. The fourth joint 134 and the third joint 133 cooperate to reinforce the fixation between the laminated glass 11 and the fixing member 12.
[0055] In this embodiment, the radii of curvature of the laminated glass 11 and the fixing member 12 in the direction of the splice line between the laminated glass 11 and the fixing member 12 are 3800 mm or less and 2200 mm or more, respectively. Therefore, while ensuring the splice strength between the laminated glass 11 and the fixing member 12, the surface of the fixing member 12 is optimized to have a certain transition uniformity from the splice line toward the roof of the vehicle body, and the optical surface precision of the electromagnetic wave signal window of the fixing member 12 is optimized. Specifically, within a range of ±100 mm, the radii of curvature of the surfaces of the fixing member 12 and the laminated glass 11 on both sides of the splice line are both 2500 mm or more, thereby avoiding insufficient strength due to sharp bending of the surface of the laminated glass 11 or the surface of the fixing member 12. As can be seen, in this embodiment, the splice strength between the laminated glass 11 and the fixing member 12 is 105 kg or more.
[0056] The transverse curvature radius in the direction of the splice line refers to the degree of bending in the extension direction of the connection line between the laminated glass 11 and the fixing member 12, as shown in Figure 1, and can also be understood as the degree of inward or outward bending in a direction perpendicular to the laminated glass 11.
