Abstract

According to the vehicle window glass, the polarizing film is arranged on the vehicle window glass, and the included angle is formed between the polarization direction of the polarizing film and the polarization direction of the polarized light emitted by the electronic display screen, so that people outside a vehicle cannot observe information displayed by the electronic display screen, namely, the visibility of the outer side of the vehicle can be reduced, and the privacy in the vehicle is protected. Besides, compared with the mode of reducing the visible light transmittance of the vehicle window glass in the prior art, the visible light transmittance of the vehicle window glass provided with the polarizing film is relatively high, so that the influence on the observation effect of the outer side of the vehicle is small, and the driving experience and safety are greatly improved. Besides, compared with the mode that a peep-proof film is arranged on an electronic display screen in the related technology, the display effect of the electronic display screen is not affected due to the fact that the peep-proof film does not need to be arranged on the electronic display screen, wide-angle display in the vehicle is facilitated, and the problem that the display effect is reduced due to the fact that the peep-proof film is pasted is solved.

Description

Technical Field

[0001] The present application relates to the field of glass technology, and in particular to a vehicle. Background Art

[0002] With the advancement of technology, transportation vehicles, such as cars, private vehicles, coaches, and buses, are becoming increasingly intelligent, gradually becoming mobile living spaces. Taking cars as an example, to enhance passenger comfort and entertainment, a growing number of vehicles are equipped with various electronic display screens (also known as liquid crystal displays) inside their interiors. These include head unit displays, central control screens, and rear seat displays. Furthermore, portable display devices (such as mobile phones and tablets) carried by passengers are also widely used in vehicles. These displays not only provide entertainment but also display important information such as navigation, vehicle status, stock information, personal photos, and work documents, greatly enhancing the driving experience.

[0003] To prevent the contents of the electronic display screen inside the car from being seen by people outside the car, related technologies usually apply anti-peep film to the electronic display screen. Some also install curtains on the car window glass, apply low-transmittance film, or set dimming film to reduce the visible light transmittance. However, applying anti-peep film can prevent the contents of the electronic display screen inside the car from being seen by people outside the car to a certain extent, but it will reduce the display effect and is not conducive to wide-angle display inside the car. In addition, the transmittance of the car window glass can be reduced by adding a light-shielding layer to the car window glass, but this will also reduce the visibility of the outside world from inside the car. Summary of the Invention

[0004] Based on this, it is necessary to overcome the defects of the existing technology and provide a means of transportation that can have a privacy protection function for the electronic display screen inside the vehicle without affecting the observation effect of the outside of the vehicle.

[0005] A means of transport, comprising:

[0006] Vehicle body;

[0011] In one embodiment, the laminated glass includes a first glass plate, a first adhesive layer, a second adhesive layer, and a second glass plate connected in sequence; and the polarizing film is connected between the first adhesive layer and the second adhesive layer.

[0012] In one embodiment, the substrate of the polarizing film is polyvinyl alcohol, cellulose triacetate or polyethylene terephthalate.

[0013] In one embodiment, the glass transition temperature Tg of the substrate is ≥50°C.

[0014] In one embodiment, the thickness of the polarizing film is D, 0.01 mm ≤ D ≤ 1 mm.

[0015] In one embodiment, the glass body is configured as a single piece of glass, and the polarizing film is connected to the inner side or the outer side of the glass body.

[0016] In one embodiment, the vehicle window glass further includes an adhesive backing disposed between the glass body and the polarizing film, and the polarizing film is connected to the glass body via the adhesive backing.

[0017] In one embodiment, the polarizing film is disposed on the inner side of the glass body through a film lamination process.

[0018] In one embodiment, the vehicle window glass further includes a protective layer, and the protective layer is disposed on a side of the polarizing film that is away from the glass body.

[0019] In one embodiment, the hardness of the protective layer is ≥2H.

[0020] In one embodiment, the visible light transmittance of the vehicle window glass is TL, 1%≤TL≤50%.

[0021] In one embodiment, the visible light transmittance of the polarizing film is 10% to 80%.

[0022] In one embodiment, the visible light transmittance of the polarizing film is 35% to 60%.

[0023] In one embodiment, the vehicle window glass includes at least one of a side windshield, a rear windshield, and a sunroof glass.

[0024] In one embodiment, the side windshield includes a front door glass, the front door glass includes a first area and a second area, the first area and the second area are arranged in sequence along the front-to-back direction, the visible light transmittance of the first area is higher than the visible light transmittance of the second area, the polarizing film is arranged in the second area, and the polarizing film is not arranged in the first area.

[0025] In one embodiment, the electronic display screen includes at least one of a vehicle display screen, a central control large screen, a rear seat display screen and a liftable display screen; and / or, the electronic display screen includes a polarization element.

[0026] In the above-mentioned means of transportation, since the window glass is provided with a polarizing film, the polarization direction of the polarizing film is set at an angle to the polarization direction of the polarized light emitted by the electronic display screen. In this way, people outside the vehicle cannot observe the information displayed on the electronic display screen, that is, the visibility outside the vehicle can be reduced, thereby protecting the privacy inside the vehicle. In addition, compared with the method of reducing the visible light transmittance of the window glass in the related art, the visible light transmittance of the window glass provided with a polarizing film is relatively high, which has less impact on the observation effect outside the vehicle, greatly improving the driving experience and safety.

[0034] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0035] An embodiment of the present application provides a means of transport, which includes but is not limited to automobiles, private cars, passenger cars, buses, trains, trains, airplanes, ships, etc. In this embodiment, the vehicle is specifically taken as an example, but is not limited thereto.

[0036] See also Figure 1 and Figure 2 , Figure 1 The following diagram shows the effect of observing the vehicle outside when the vehicle window glass 20 in the related art is used. Figure 2 The diagram illustrates the outside-vehicle observation effect when the vehicle window glass 20 of one embodiment of the present application is in use. Specifically, the vehicle includes a vehicle body, an electronic display screen 10 and a vehicle window glass 20. The electronic display screen 10 is arranged inside the vehicle body. The electronic display screen 10 includes but is not limited to at least one of a vehicle display screen, a central control large screen, a rear seat display screen and a liftable display screen. The electronic display screen 10 emits polarized light when in operation. The vehicle window glass 20 includes but is not limited to at least one of a side windshield, a rear windshield and a sunroof glass. Among them, the side windshield can be a front door glass or a rear door glass. The vehicle window glass 20 is arranged on the vehicle body.

[0037] Please also refer to Figures 3 to 6 In any of the figures, the vehicle window glass 20 includes a glass body 21 and a polarizing film 22 connected to the glass body 21. The polarization direction of the polarizing film 22 is at an angle with the polarization direction of the polarized light, where the angle is a, 0°<a<180°.

[0038] In the above-mentioned vehicle, since the window glass 20 is provided with a polarizing film 22, the polarization direction of the polarizing film 22 is set at an angle to the polarization direction of the polarized light emitted by the electronic display screen 10, so that people outside the vehicle cannot see the information displayed on the electronic display screen 10, that is, the visibility outside the vehicle can be reduced, thereby protecting the privacy inside the vehicle. Figure 1 and Figure 2 , Figure 2 Compared with Figure 1 In other words, the information displayed on the electronic display screen 10 cannot be observed by people outside the vehicle. Furthermore, compared to the related art method of reducing the visible light transmittance of the vehicle window glass 20, the visible light transmittance of the vehicle window glass 20 equipped with the polarizing film 22 is relatively high, which lessens the effect on the view from the outside of the vehicle, greatly improving the driving experience and safety. Furthermore, compared to the related art method of installing an anti-privacy film on the electronic display screen 10, since the anti-privacy film is not required, the display quality of the electronic display screen 10 is not affected, facilitating wide-angle display in the vehicle, thus avoiding the problem of reduced display quality caused by the application of an anti-privacy film.

[0039] In some embodiments, 45°<a<135°. Specifically, a includes but is not limited to 46°, 50°, 55°, 60°, 70°, 75°, 80°, 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130° or 134°, etc. When a is closer to 90°, the visibility of the display information of the electronic display screen 10 to the outside of the vehicle is lower. Therefore, by flexibly adjusting the size of a and designing the flip angle of the polarizing film 22 accordingly, it is possible to effectively reduce the visibility of the display information of the electronic display screen 10 to the outside of the vehicle without affecting the observation of the outside of the vehicle by the passengers in the vehicle, thereby protecting the privacy of the content on the display screen in the vehicle, and avoiding the problem of reduced display effect caused by applying anti-peep film, thereby greatly improving the driving experience and safety.

[0040] It should be noted that the window glass 20 can be a single piece of glass, such as Figure 5 and Figure 6 As shown, it can also be laminated glass, such as Figure 3 and Figure 4 As shown, it is not limited here. Among them, the laminated glass can be double-layer glass, triple-layer glass or more layers of glass, which can be flexibly adjusted and set according to actual needs. In this embodiment, the laminated glass is specifically expanded by taking double-layer glass as an example.

[0041] See also Figure 3 and Figure 4 For example, when the glass body 21 includes laminated glass, the polarizing film 22 can be disposed not only on the inner side and the outer side of the glass body 21, but also on the outer side. Figure 4 As shown, it can also be set inside the glass body 21, such as Figure 3As shown. The inner side of the glass body 21 refers to the side of the glass body 21 facing the interior of the vehicle, and the outer side of the glass body 21 refers to the side of the laminated glass facing the exterior of the vehicle. When the polarizing film 22 is disposed within the glass body 21, the glass body 21 provides better protection for the polarizing film 22. Compared to when the polarizing film 22 is disposed externally, this protects the polarizing film 22 from being exposed and causing defects such as friction, scratches, bubbles, and aging, thereby extending the service life of the glass body 21.

[0042] See also Figure 3 For example, laminated glass includes a first glass plate 211, a first adhesive layer 212, a second adhesive layer 213, and a second glass plate 214, which are sequentially connected. A polarizing film 22 is connected between the first adhesive layer 212 and the second adhesive layer 213. Thus, during the laminated glass lamination process, the first glass plate 211, the first adhesive layer 212, the polarizing film 22, the second adhesive layer 213, and the second glass plate 214 are stacked together and placed in an autoclave for lamination under high temperature and pressure, thereby improving production efficiency and reducing production costs.

[0043] Based on the above embodiments, the first adhesive layer 212 and the second adhesive layer 213 both mainly play an adhesive role, and are independently set and adjusted according to actual needs, including but not limited to being made of PVB material, EVA material, TPU material or SGP material.

[0044] The first glass plate 211 is, for example, an outer glass plate facing the external environment of the vehicle body, and the second glass plate 214 is correspondingly configured as an inner glass plate facing the internal environment of the vehicle body.

[0045] As some optional solutions, the first adhesive layer 212 in the above embodiment can be omitted, and the vehicle window glass 20 correspondingly includes a first glass plate 211, a polarizing film 22, a second adhesive layer 213 and a second glass plate 214 connected in sequence; the second adhesive layer 213 in the above embodiment can also be omitted, and the vehicle window glass 20 correspondingly includes a first glass plate 211, a first adhesive layer 212, a polarizing film 22 and a second glass plate 214 connected in sequence.

[0046] It should be noted that the polarizing film 22 can be applied to various types and materials of vehicle window glass 20, thus having a wide range of applications. Furthermore, whether the electronic display 10 utilizes a traditional LCD display or an emerging OLED display, since the electronic display 10 emits polarized light during operation, when combined with vehicle window glass 20 having the polarizing film 22, a privacy protection function can be achieved.

[0047] For example, the polarizing film 22 is classified by function, including but not limited to any one of a transmissive polarizer, a reflective polarizer, a semi-transmissive and semi-reflective polarizer and a compensation polarizer; classified by dyeing method, including but not limited to any one of an iodine-based polarizer and a dye-based polarizer; classified by material type, including but not limited to any one of a metal polarizer, an iodine-based polarizer, a dye-based polarizer and an ethylene polarizer. The specific type is flexibly adjusted and set according to actual needs and is not limited here.

[0048] For example, the substrate used for the polarizing film 22 can be flexibly adjusted and configured according to actual needs and is not limited here. For example, the substrate can be polyvinyl alcohol (PVA), triacetyl cellulose (TAC), or polyethylene terephthalate (PET).

[0049] To meet the requirements of high-temperature and high-pressure processing of laminated glass, the substrate may optionally have a glass transition temperature (Tg) of 50°C or higher. Specifically, Tg may be 50°C, 80°C, 85°C, 90°C, 100°C, 110°C, 115°C, 120°C, 125°C, 130°C, 140°C, 150°C, or 160°C. Preferably, Tg is 90°C or higher.

[0050] Based on the aforementioned embodiment, the thickness D of the polarizing film 22 is 0.01 mm ≤ D ≤ 1 mm. Specifically, D is, for example, 0.01 mm, 0.02 mm, 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, or 1 mm. Thus, on the one hand, when the thickness D of the polarizing film 22 is ≤ 1 mm, the thickness is not too large to result in a low visible light transmittance, thereby ensuring that the visible light transmittance of the vehicle window glass 20 meets the required value. On the other hand, when the thickness D is ≥ 0.01 mm, the thickness is not too small to result in a glass transition temperature Tg that does not meet the required value, thereby ensuring that the glass transition temperature Tg meets the required value.

[0051] See also Figure 5 and Figure 6 In another embodiment, when the glass body 21 is a single piece of glass, the glass body 21 is, for example, tempered glass. Furthermore, the polarizing film 22 can be disposed on either the inner side or the outer side of the glass body 21. When the polarizing film 22 is disposed on the inner side of the glass body 21, it can help prevent damage caused by wind and sun, thereby extending the service life.

[0052] See also Figure 5 and Figure 6In addition to the aforementioned embodiment, the vehicle window glass 20 further includes an adhesive backing 23 disposed between the glass body 21 and the polarizing film 22. The polarizing film 22 is attached to the glass body 21 via the adhesive backing 23. This adhesive fixation of the polarizing film 22 to the glass body 21 not only enhances the film's durability but also avoids potential safety hazards associated with adhesive films or coatings.

[0053] Optionally, the polarizing film 22 is disposed on the inner side of the glass body 21 through a film lamination process, a coating process, or a vacuum coating process.

[0054] When the glass body 21 is a flat glass, the polarizing film 22 can be applied mechanically or manually. When the glass body 21 is a curved glass, manual application is usually used to ensure the quality of the application.

[0055] See also Figure 5 and Figure 6 In addition to the above embodiment, the vehicle window glass 20 further includes a protective layer 24, which is disposed on the side of the polarizing film 22 facing away from the glass body 21. Thus, the protective layer 24 protects the polarizing film 22 from various defects such as friction, scratches, bubbles, and aging caused by exposure to the polarizing film 22, thereby extending the service life of the polarizing film 22.

[0056] For example, the protective layer 24 is a hard coating. The hardness of the hard coating is ≥ 2H. Specifically, the hardness of the hard coating is 2H, 3H, 4H, 5H, 6H, or 10H. The hardness of the hard coating is preferably greater than 5H. Thus, the hardness of the hard coating is relatively high, thereby increasing the hardness of the polarizing film 22, so that the hardness of the polarizing film 22 is 3H to 5H, or even greater than 5H, providing a better protective effect.

[0057] When the hardness of the polarizing film 22 is relatively high, for example, greater than 5H, it is not easily damaged and has a longer service life.

[0058] For example, the hardening coating is formed on the polarizing film 22 by a wet film process, wherein the wet film process includes but is not limited to spray coating, flow coating or dip coating.

[0059] For example, the polarizing film 22 is a transparent material, and the visible light transmittance of the polarizing film 22 includes but is not limited to 10% to 80%, specifically 10%, 35%, 36%, 37%, 38%, 39%, 40%, 45%, 50%, 60% or 80%. In addition, the visible light transmittance of the glass body 21 is ≥10%, specifically 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% or 95%. After the glass body 21 and the polarizing film 22 are combined, the visible light transmittance of the vehicle window glass 20 is TL, which is between 1% and 50%, specifically 1%, 10%, 15%, 25%, 33%, 34%, 35%, 40%, 45% or 50%. In this way, the visible light transmittance TL of the vehicle window glass 20 is large and does not affect the observation effect of the passengers inside the car on the outside of the car.

[0060] Specifically, when the side windshields, rear windshield and sunroof glass are all set to the vehicle window glass 20 of the above embodiment, privacy protection can be achieved in all directions of the left and right sides, rear side and top side of the vehicle body, with good privacy protection effect.

[0061] Side windshields include, but are not limited to, front door glass and rear door glass. To achieve enhanced privacy protection, the rear door glass can be configured as the vehicle window glass 20 described in any of the aforementioned embodiments. In this manner, the visible light transmittance of the rear door glass can be set, for example, to 1% to 50%, thereby providing privacy protection. Furthermore, the front door glass includes a first region and a second region, which are arranged in a front-to-back direction. The visible light transmittance of the first region is higher than that of the second region. A polarizing film 22 is provided in the second region, eliminating the need for the first region. This ensures that the first region is closer to the rearview mirror and has a higher visible light transmittance, facilitating observation of the exterior of the vehicle from within the vehicle and enhancing safety. Furthermore, the visible light transmittance of the second region is lower, providing enhanced privacy protection.

[0062] In one embodiment, electronic display screen 10 includes a polarizing element.

[0063] Optionally, the polarizing element includes but is not limited to a film material with polarization function, that is, similar to the polarizing film 22 in the above embodiment, except that the angle with the polarization direction of the polarizing film 22 is, for example, 0°<a<180°.

[0064] In summary, the present application has at least the following technical effects: it can achieve privacy protection of the content of the electronic display screen 10 without affecting the passenger's observation of the outside of the vehicle. This can not only improve the privacy protection of passengers, but also improve driving safety, and meet the needs of modern transportation for privacy protection and driving safety. Specifically, since the present technical solution does not require a privacy film to be affixed to the in-vehicle display screen or reduce the transmittance of the glass, it will not affect the display effect of the in-vehicle display screen and the effect of external observation from inside the vehicle, which will greatly enhance the driving experience. In the field of optical technology, the present technical solution reduces the visibility from the outside of the vehicle by superimposing a polarizing film 22 on the vehicle window glass 20 and designing the flip angle of the polarizing film 22. This new optical technology can be applied to the manufacturing process of the vehicle window glass 20 to improve the privacy protection performance of the vehicle window glass 20 and meet the market demand for vehicle window glass 20 with high privacy protection performance. In the field of display technology, the present technical solution reduces the visibility from the outside of the vehicle by superimposing a polarizing film 22 on the vehicle window glass 20 and designing the flip angle of the polarizing film 22. This new display technology can be applied in the manufacturing process of the electronic display screen 10 to improve the privacy protection performance of the electronic display screen 10 and meet the market demand for electronic display screens 10 with high privacy protection performance.

[0065] In one embodiment, the present application further provides a privacy protection method for an electronic display screen 10 that uses a polarizing film 22 to reduce visibility outside a vehicle. The specific steps are as follows:

[0066] Step S10: preparing a first glass plate 211, a second glass plate 214, a first adhesive layer 212, and a second adhesive layer 213;

[0067] Step S20, preparing the polarizing film 22;

[0068] Optionally, the substrate of the polarizing film 22 includes but is not limited to PVA / TAC or other materials, the glass transition temperature Tg of the substrate is greater than 80° C., and the thickness of the substrate is less than 1 mm;

[0069] Step S30, adjusting the angle a between the polarization direction of the polarizing film 22 and the polarization direction of the electronic display, 45°<a<135°;

[0070] Step S40: placing the polarizing film 22 with the adjusted angle between the first glass plate 211 and the second glass plate 214, with the first adhesive layer 212 positioned between the polarizing film 22 and the first glass plate 211, and the second adhesive layer 213 positioned between the polarizing film 22 and the second glass plate 214. The polarizing film 22 is fixed between the first glass plate 211 and the second glass plate 214 through a high-temperature and high-pressure process to form a laminated glass product structure.

[0071] Step S50: Testing the formed laminated glass to ensure that it meets the requirements of privacy protection inside the vehicle while not affecting passengers' observation of the outside of the vehicle.

[0072] Through the above steps, a method for protecting the privacy of a car display screen by using a polarizing film 22 to reduce visibility outside the car can be implemented, thereby solving the problem in the related art that sticking an anti-peep film on the electronic display screen 10 will reduce the display effect and affect the viewing experience of passengers in the car. At the same time, it also solves the problem in the related art that although reducing the transmittance of the glass can prevent the content of the display screen inside the car from being seen by people outside the car, it will also reduce the effect of observing the outside world from inside the car, affecting driving safety.

[0073] It should be noted that, in the present application, the polarizing film 22 can control the polarization direction of a specific light beam. When natural light passes through the polarizing film 22, light with a vibration direction perpendicular to the transmission axis of the polarizing film 22 is absorbed, leaving only polarized light with a vibration direction parallel to the transmission axis of the polarizing film 22.

[0074] Optionally, the core polarizing film material in the polarizing film 22 is a PVA film. After dyeing, the PVA film adsorbs iodine molecules with biaxial absorption. Stretching the PVA film causes the iodine molecules to be orderly arranged on the PVA film, forming a polarizing film with uniform biaxial absorption properties, with its transmission axis perpendicular to the stretching direction.
