[0001] The present invention relates to the technical field of glass, and in particular to a laminated glass, a vehicle and a method for manufacturing the laminated glass. Background Art

[0002] Laminated glass is widely used in vehicles due to its advantages such as heat insulation, noise reduction, UV radiation reduction, and durability. Furthermore, with the electrification, networking, intelligence, and sharing of vehicles, functional modules such as onboard cameras, LiDAR, and infrared cameras are increasingly being installed in vehicles. These modules contribute to improving the driving experience and safety.

[0003] With the continuous development of advanced driver-assistance systems (ADAS), when a car performs autonomous or assisted driving, it needs to collect a large amount of data about the environment in front of the car. Therefore, on-board cameras play an important role in image data collection. However, laminated glass in existing technology is usually composed of two or more layers of glass, with an intermediate layer between adjacent glass. When an on-board camera collects image data through laminated glass, it is easily affected by the light transmittance, refractive index, and curvature radius of the multiple layers of glass, thereby reducing the image data collection accuracy of the on-board camera.

[0004] Therefore, how to reduce the impact of laminated glass on vehicle cameras to improve the accuracy of image data acquisition has become a technical problem that needs to be solved urgently.

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0055] Implementation Method 1

[0056] Please refer to Figure 1 and Figure 2As shown, an embodiment of the present invention provides a laminated glass 1, which includes a first glass plate 100, a second glass plate 200, an intermediate connecting layer 300, and a strengthening member 400. The intermediate connecting layer 300 is located between the first glass plate 100 and the second glass plate 200 and is used to connect the first glass plate 100 and the second glass plate 200. The laminated glass 1 also includes at least one through hole 210, which passes through the second glass plate 200 and the intermediate connecting layer 300. Along the stacking direction of the first glass plate 100 and the second glass plate 200, the strengthening member 400 is located within the projection range of the through hole 210 and is connected to the first glass plate 100. A sealing structure 500 is provided between the strengthening member 400 and the intermediate connecting layer 300 and / or the second glass plate 200.

[0057] Please refer to Figure 1 and Figure 2 As shown, an optical sensor 2 is provided on the side of the second glass plate 200 facing away from the intermediate connecting layer 300, and the laminated glass 1 has an information collection area for signal transmission from the optical sensor 2; a through hole 210 is arranged opposite to the optical sensor 2, and along the stacking direction of the first glass plate 100 and the second glass plate 200, the projection range of the through hole 210 is larger than the information collection area.

[0058] By providing a through hole 210 on the second glass plate 200 and removing the intermediate connecting layer 300 within the range covered by the through hole 210, the optical sensor 2 only needs to pass through the first glass plate 100 to transmit the optical signal. This avoids the influence of the light transmittance, refractive index and curvature radius of the second glass plate 200 and the intermediate connecting layer 300 on the optical sensor 2, and significantly improves the acquisition accuracy of the optical sensor 2.

[0059] Generally speaking, when the laminated glass 1 is used, it is assembled into a windshield and installed on a vehicle, with the first glass sheet 100 positioned on the vehicle's exterior and the second glass sheet 200 positioned on the vehicle's interior. By disposing the strengthening member 400 on the first glass sheet 100 within the area covered by the through-hole 210, the strengthening member 400 reinforces the area where the through-hole 210 is located, thereby reducing or eliminating the weakening of the laminated glass 1 caused by the through-hole 210. This helps to enhance the overall structural strength of the laminated glass 1, thereby improving the safety performance of the vehicle.

[0060] In addition, a sealing structure 500 is provided in the peripheral gap of the reinforcing member 400. The sealing structure 500 can seal and fix the reinforcing member 400 and the intermediate connecting layer 300 and / or the second glass plate 200, thereby helping to improve the structural stability of the reinforcing member 400 and preventing foreign matter from entering the laminated glass 1 along the gap.

[0061] It should be noted that the optical sensor 2 includes but is not limited to a visible light camera, a near-infrared camera, a laser radar, etc.

[0062] In an embodiment of the present invention, the number of through holes 210 in the laminated glass 1 is at least one, and the strengthening member 400 is provided in a one-to-one correspondence with each through hole 210. Multiple through holes 210 can correspond one-to-one to multiple optical sensors 2, or a single through hole 210 can correspond to multiple optical sensors 2.

[0063] In a specific embodiment, when there is only one through hole 210 and only one optical sensor 2, the signal transmission requirements of the optical sensor 2 can be met through the through hole 210. Of course, by increasing the area of ​​the through hole 210, the signal transmission requirements of multiple optical sensors 2 can also be met through the through hole 210.

[0064] In another specific embodiment, when the laminated glass 1 includes multiple through holes, the multiple through holes 210 can be arranged at intervals. The multiple through holes 210 can respectively meet the signal transmission requirements of different optical sensors 2, thereby having better applicability.

[0065] Designers can adjust the specific shape and number of the through holes 210 according to usage requirements. For example, the through holes 210 can be set to be circular, rectangular, elliptical or other shapes, which are not specifically limited here.

[0066] In one embodiment of the present invention, when the through hole 210 is circular, the diameter of the through hole 210 is 1 cm to 10 cm larger than the diameter of the circumscribed circle of the information collection area. This is because an excessively large diameter of the through hole 210 can reduce the overall strength of the laminated glass 1 and affect its performance. However, an excessively small diameter of the through hole 210 can affect signal transmission from the optical sensor 2 within the vehicle.

[0067] In the embodiments of the present invention, the designer may adjust the specific materials and structures of the first glass plate 100 and the second glass plate 200 according to the actual use requirements, and no specific limitation is imposed herein. Specifically, the first glass plate 100 may be configured as physically tempered glass, which can be obtained by heat-treating ordinary glass.

[0068] Furthermore, designers can adjust the specific composition and structure of the intermediate connecting layer 300 according to usage requirements. For example, the intermediate connecting layer 300 can be formed of EVA material, or the intermediate connecting layer 300 can be formed of PVB material, or the intermediate connecting layer 300 can be formed of a composite of EVA material and PVB material, or the intermediate connecting layer 300 can be formed of other materials. No specific restrictions are imposed here.

[0069] When the reinforcing member 400 is in the through hole 210, it can support and reinforce the laminated glass 1. In the embodiment of the present invention, preferably, along the stacking direction of the first glass sheet 100 and the second glass sheet 200, the thickness of the reinforcing member 400 is not less than the thickness of the intermediate connecting layer 300.

[0070] In a specific embodiment, the thickness of the reinforcement member 400 is 0.38 mm to 1.6 mm. Specifically, the thickness of the reinforcement member 400 is 0.38 mm, 0.635 mm, 0.7 mm, 1.0 mm, 1.1 mm, 1.27 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, etc.

[0071] Increasing the thickness of the reinforcing member 400 can improve the structural strength of the reinforcing member 400, thereby providing better reinforcement for the laminated glass 1. Furthermore, by ensuring that the thickness of the reinforcing member 400 is not less than that of the intermediate connecting layer 300, the side edges of the reinforcing member 400 can block the intermediate connecting layer 300, thereby improving the structural stability of the intermediate connecting layer 300.

[0072] In the embodiment of the present invention, since the reinforcing member 400 is located inside the through hole 210 and a sealing structure 500 is provided between the reinforcing member 400 and the intermediate connecting layer 300 and / or the second glass plate 200, the peripheral gap of the reinforcing member 400 has a certain impact on the sealing and installability of the laminated glass 1.

[0073] For example, if the peripheral gap of the reinforcing member 400 is too small, it will affect the installation of the sealing structure 500. If the peripheral gap of the reinforcing member 400 is too large, it will affect the sealing performance of the laminated glass 1.

[0074] As described above, in the embodiment of the present invention, along the width direction of the laminated glass 1 , the single-side distance between the reinforcement member 400 and the edge of the through hole 210 in the intermediate connecting layer 300 and / or the second glass plate 200 is less than or equal to 5 mm.

[0075] Preferably, the single-side distance between the reinforcing member 400 and the edge of the through hole 210 on the intermediate connecting layer 300 and / or the second glass plate 200 is less than or equal to 4 mm.

[0076] More preferably, the single-side distance between the reinforcing member 400 and the edge of the through hole 210 on the intermediate connecting layer 300 and / or the second glass plate 200 is less than or equal to 3 mm.

[0077] More preferably, the single-side distance between the reinforcing member 400 and the edge of the through hole 210 on the intermediate connecting layer 300 and / or the second glass plate 200 is less than or equal to 2 mm.

[0078] More preferably, the single-side distance between the reinforcing member 400 and the edge of the through hole 210 on the intermediate connecting layer 300 and / or the second glass plate 200 is less than or equal to 1 mm.

[0079] When the optical sensor 2 is a visible light camera, in order to prevent the reinforcement 400 from affecting image data collected by the visible light camera on the vehicle, in an embodiment of the present invention, the optical transmittance of the reinforcement 400 in the wavelength range of 380nm-780nm is ≥85%.

[0080] When the optical sensor 2 is a laser radar, in order to avoid the influence of the reinforcement 400 on the laser radar signal transmission on the vehicle, in an embodiment of the present invention, the optical transmittance of the reinforcement 400 in the wavelength range of 800nm-1550nm is ≥80%.

[0081] In this embodiment of the present invention, ink (not shown) is applied to the edges of the laminated glass 1, with some of the ink surrounding the information collection area. This ink serves to shield and protect the vehicle's interior components, ensuring an overall aesthetic appearance when viewed from the outside. Furthermore, the ink also provides UV protection, preventing internal components from aging and damage due to direct sunlight, thereby extending the vehicle's service life.

[0082] In this embodiment of the present invention, the strengthening member 400 includes a strengthening film 410. The strengthening film 410 is positioned within the projection of the through-hole 210 and is fixedly bonded to the first glass plate 100. By positioning the strengthening film 410 within the projection of the through-hole 210 and securely attaching it to the first glass plate 100, the strengthening film 410 provides structural reinforcement for the area covered by the through-hole 210, thereby increasing the structural strength of the laminated glass at the through-hole 210 and reducing or eliminating any weakening of the laminated glass caused by the through-hole 210.

[0083] The designer can adjust the specific shape of the strengthening film 410 according to the actual use requirements, and no specific limitation is imposed here. Preferably, the strengthening film 410 is arranged in a conformal manner to the through hole 210, and the strengthening film 410 can cover or substantially cover the projection area of ​​the through hole 210, thereby effectively enhancing the strengthening effect of the strengthening film 410 on the laminated glass 1.

[0084] In an embodiment of the present invention, the strengthening film 410 can be transparent, or a colored strengthening film 410 can be designed according to the optical signal transmittance requirements of the optical sensor 2, thereby meeting the aesthetic requirements of the laminated glass 1 and the signal transmission performance requirements of the optical sensor 2 to the laminated glass 1.

[0085] In one embodiment of the present invention, the strengthening film 410 is a polymer explosion-proof film. An adhesive layer 411 is provided on the end surface of the strengthening film 410 facing the first glass plate 100. The strengthening film 410 is bonded to the first glass plate 100 via the adhesive layer 411. Preferably, the polymer explosion-proof film has UV resistance to prevent ultraviolet rays from sunlight from entering the vehicle interior.

[0086] The adhesive layer 411 can be used to adhere the polymer explosion-proof film to the inner side of the first glass plate 100, achieving better fixing efficiency. Furthermore, the adhesive layer 411 can help eliminate air bubbles between the polymer explosion-proof film and the first glass plate 100, thereby preventing light distortion.

[0087] The designer can adjust the specific structure of the adhesive layer 411 according to the use requirements, and no specific limitation is imposed here. Preferably, the adhesive layer 411 and the strengthening film 410 are arranged in a conformal manner.

[0088] In one embodiment, the polymer explosion-proof film is a PET polyester film.

[0089] In another specific embodiment, the polymer explosion-proof film is a TPU polyurethane film.

[0090] In another specific embodiment, the polymer explosion-proof film is a BOPP polypropylene film.

[0091] In other feasible embodiments, the polymer explosion-proof film may be composed of various combinations of PET polyester film, TPU polyurethane film and BOPP polypropylene film.

[0092] Of course, designers can adjust the specific materials of the polymer explosion-proof membrane according to usage needs, and no specific restrictions are made here.

[0093] In one embodiment, the elongation of the strengthening film 410 is greater than or equal to 300%.

[0094] In another embodiment, the fracture strength of the strengthening film 410 is greater than or equal to 90 N / cm.

[0095] In yet another embodiment, the peel strength of the strengthening film 410 is greater than or equal to 15 N / 25 mm.

[0096] In other feasible embodiments, the elongation of the strengthening film 410 is ≥300%, the breaking strength is ≥90 N / cm, and the peeling strength is ≥15 N / 25 mm.

[0097] In another feasible embodiment of the present invention, the strengthening member 400 comprises a glass sheet, and the glass sheet is connected to the first glass plate 100 by vacuum adsorption. Preferably, the glass sheet is physically tempered glass or chemically tempered glass.

[0098] In one embodiment, the strengthening film 410 is chemically tempered glass. The strength of the glass can be increased by changing the chemical composition of the glass surface. Chemically tempered glass can be obtained by tempering the glass using an ion exchange method. The main component of the chemically tempered glass is high alumina-silicate glass or lithium alumina-silicate glass.

[0099] In another embodiment, the strengthening film 410 is physically tempered glass. Physically tempered glass can be obtained by heat-treating ordinary glass. The physically tempered glass is selected from at least one of soda-lime glass, aluminosilicate glass, lithium aluminosilicate glass, or borosilicate glass.

[0100] By vacuum-attaching the glass sheet to the inner side of the first glass plate 100, the gap between the strengthening member 400 and the first glass plate 100 is eliminated, thereby preventing light distortion. Furthermore, vacuum-attaching the glass sheet to the first glass plate 100 prevents foreign matter from entering the laminated glass 1.

[0101] In another embodiment of the present invention, the strengthening member 400 further includes a functional film (not shown). One side of the glass sheet is connected to the first glass plate 100, and the other side of the glass sheet is connected to the functional film. The functional film is at least one of an antireflection film, a visible light-cutting infrared-transmitting film, and a tinting film. The strengthening member 400 can enable the laminated glass 1 to achieve functions such as visible light cutoff, antireflection of optical signals in specific wavelength bands, and tinting effects.

[0102] For example, an antireflection coating can reduce reflection of signal light from optical sensor 2 by laminated glass 1, thereby increasing its transmittance. A visible-light-cutting infrared-transmitting film is an optical film that completely shields the information collection area without attenuating infrared signal transmittance. For example, the optical transmittance of this film is less than 1% within the 380nm-780nm wavelength range and greater than 90% within the 920nm-980nm wavelength range. This film can be the same color as the ink, enhancing the aesthetics of laminated glass 1. Colored films can also be designed based on the optical signal transmittance requirements of optical sensor 2, thereby satisfying both the aesthetic requirements of laminated glass 1 and the signal transmission performance requirements of optical sensor 2.

[0103] In an embodiment of the present invention, the sealing structure 500 includes a sealing member 510, which is disposed in the gap between the strengthening member 400 and the intermediate connecting layer 300 and / or the second glass sheet 200. The sealing member 510 provides a seal, thereby improving the structural stability of the strengthening member 400 and preventing foreign matter from entering the laminated glass 1 through the gap.

[0104] Specifically, the gap between the reinforcing member 400 and the intermediate connecting layer 300 and / or the second glass plate 200 is filled with a sealant, which solidifies to form the sealing member 510. Preferably, a sealant ring is provided in the gap between the reinforcing member 400 and the intermediate connecting layer 300 and the second glass plate 200.

[0105] Designers can adjust the specific type of sealant according to usage needs. For example, the sealant can be a combination of one or more of heat-curing sealant, moisture-curing sealant and UV-curing sealant, which is not specifically limited here.

[0106] In this embodiment of the present invention, since a sealing structure 500 is provided between the strengthening member 400 and the intermediate connecting layer 300 and / or the second glass plate 200, during the manufacturing process, the through hole in the intermediate connecting layer 300 can be reduced in size to prevent impurities or sealant from entering between the intermediate connecting layer 300 and the second glass plate 200. Preferably, the radial dimension of the through hole of the intermediate connecting layer 300 is less than or equal to 2 mm larger than the radial dimension of the through hole of the second glass plate 200.

[0107] Implementation Method 2

[0108] The embodiment of the present invention further provides a vehicle, which includes the laminated glass 1 described in Embodiment 1. The specific structure, working principle and beneficial effects of the laminated glass 1 are the same as those described in Embodiment 1 and will not be described in detail here.

[0109] In an embodiment of the present invention, a vehicle includes at least one windshield, which is formed by laminated glass 1. Preferably, the vehicle has a front windshield, which is formed by laminated glass 1. The vehicle may also include a rear windshield, which is also formed by laminated glass 1.

[0110] Of course, designers can set other glass on the vehicle to be laminated glass according to the installation requirements of the optical sensor 2, and no specific limitation is made here.

[0111] By assembling the laminated glass 1 into a windshield and installing it on a vehicle, the through hole 210 is set inside the vehicle, so that the optical sensor 2 on the vehicle can transmit signals with the help of the through hole 210, avoiding the influence of the light transmittance, refractive index and curvature radius of the second glass plate 200 and the intermediate connecting layer 300 on the optical sensor 2, significantly improving the acquisition accuracy of the optical sensor 2, and helping to ensure the driving safety of the vehicle during automatic driving or assisted driving.

[0112] Implementation Method 3

[0113] Please refer to Figure 1As shown, the embodiment of the present application further provides a manufacturing method of the laminated glass, which specifically comprises the following steps:

[0114] Step S10, providing a first glass plate 100 and a second glass plate 200 with a through hole 210;

[0115] Step S20, placing an intermediate connecting layer 300 between the first glass plate 100 and the second glass plate 200 with the through hole 210, and then removing the intermediate connecting layer 300 in the area covered by the through hole 210;

[0116] Step S30, arranging a reinforcing member 400 in the through hole 210 and connecting the reinforcing member 400 with the first glass plate 100;
