[0037] With the advancement of technology, as a modern fully automatic AI driving car, it is necessary to make every piece of glass on the car have a screen display function. For example, the car's speed, navigation and other important driving information can be projected onto the windshield in front of the driver to realize the car's head-up display function, increase the user experience and sense of technology; and the screen display function on the existing car glass usually requires additional on-board projection equipment to be installed in the car, and requires specific operators to debug the screen display, which increases costs; and is prone to poor display effects.
[0038] Based on this, in order to solve the above problems, the present application designs a vehicle glass, which is formed by combining a display film layer with a glass substrate, so that the vehicle glass has the function of serving as a screen display after power is turned on, and the structure is simple and reliable; it will not damage the structure of the glass substrate, nor will it affect the overall appearance of the glass substrate; the automotive glass no longer relies on the on-board projection equipment, and can realize the self-luminous screen display function; and an intermediate layer is set to provide a bonding force between the two, so that the two are firmly connected, thereby improving product stability.
[0039] An embodiment of the present application provides a vehicle (not shown), which includes a vehicle system and a vehicle glass 100, and the vehicle glass 100 is used to be installed on at least one of the sunroof, side windows, front windshield and rear windshield of the vehicle.
[0040] In some embodiments, reference Figure 1 , Figure 2 The automotive glass 100 includes a glass substrate 1, a display film layer 2 and an intermediate layer 3; the display film layer 2 is light-transmissive, and the display film layer 2 is arranged on the outer surface of the glass substrate 1, and / or the display film layer 2 is arranged inside the glass substrate 1; the intermediate layer 3 is light-transmissive, and the intermediate layer 3 is formed between the display film layer 2 and the glass substrate 1 and is used to provide bonding force.
[0041] It can be understood that the glass substrate 1 is used as automotive glass, and the glass substrate 1 is specifically any one of laminated glass, tempered glass and regional tempered glass.
[0042] The display film layer 2 has the function of displaying when powered on, and can be, but not limited to, an LED display screen, an LED film screen, etc. The display film layer 2 has the characteristics of being thin and light and highly transparent, and can be flexibly attached to the outer surface of the glass substrate 1. By combining the display film layer 2 with the glass substrate 1, and electrically connecting the vehicle's vehicle system with the display film layer 2, the vehicle glass 1 can be made to have the function of being a screen display after being powered on. For example: important driving information such as the vehicle's speed and navigation can be displayed on the windshield in front of the driver to realize the head-up display function of the car; or audio and video can be displayed on the screens of other seating positions in the vehicle for passengers to relax and entertain, increasing the vehicle's user experience and sense of technology.
[0043] Here, the specific number and arrangement position of the display film layer 2 are not limited; for example, when the glass substrate 1 is a laminated glass, one or more display film layers 2 may be arranged on the outer surface of the glass substrate 1; or one or more display film layers 2 may be arranged inside the interlayer of the glass substrate 1. When the glass substrate 1 is a tempered glass or a regional tempered glass, one or more display film layers 2 are arranged on the outer surface of the glass substrate 1.
[0044] The display film layer 2 can be disposed at any local position of the glass substrate 1, or the display film layer 2 can completely cover the glass substrate 1; the selection can be made according to the needs.
[0045] It can be understood that the display film layer 2 and the glass substrate 1 are firmly combined via the intermediate layer 3 , and the intermediate layer 3 is sticky. The intermediate layer 3 may be, but is not limited to, an adhesive or an adhesion promoter.
[0046] For example, when the display film layer 2 itself is a film screen, that is, the display film layer 2 itself has adhesiveness, the intermediate layer 3 can use an adhesion promoter, and the intermediate layer 3 can make the bonding between the display film layer 2 and the glass substrate 1 more firmly. When the display film layer 2 itself does not have adhesiveness, the intermediate layer 3 can use an adhesive, that is, the display film layer 2 and the glass substrate 1 are bonded and connected through the intermediate layer 3.
[0047] The automotive glass of the present application forms the automotive glass 100 by combining the display film layer 2 with the glass substrate 1, so that the automotive glass 100 has the function of serving as a screen display after being powered on, and has a simple and reliable structure; it will not damage the structure of the glass substrate 1, nor will it affect the overall appearance of the glass substrate 1; the automotive glass 100 is no longer dependent on the vehicle-mounted projection equipment, and can realize the self-luminous screen display function; and an intermediate layer is provided to provide a bonding force between the two, so that the two are firmly connected, thereby improving product stability.
[0048] It can be understood that the display film layer 2 and the glass substrate 1 are installed and debugged by the manufacturer before delivery. After the automotive glass 100 is installed on the vehicle, the screen display function can be realized by powering on.
[0049] refer to Figure 1 In some embodiments, the glass substrate 1 includes a first glass layer 4, an interlayer 5 and a second glass layer 6 which are stacked; the first glass layer 4 has a first outer side surface 401 away from the interlayer 5 and a first inner side surface 402 close to the interlayer 5; the second glass layer 6 has a second outer side surface 601 away from the interlayer 5 and a second inner side surface 602 close to the interlayer 5; the display film layer 2 is arranged on at least one of the first outer side surface 401, the first inner side surface 402, the second outer side surface 601 and the second inner side surface 602.
[0050] Specifically, the automotive glass 100 of the present application is currently required to be used for vehicle windshields, and the current vehicle windshields require the use of laminated glass, which has high transparency, cold resistance, impact resistance and sound insulation, and then the glass substrate 1 is specifically laminated glass. The interlayer 5 is an organic polymer intermediate film, and the interlayer 5 can be made of but not limited to PVB, SGP, EVA, PU, etc.
[0051] It can be understood that the display film layer 2 is specifically combined with the first glass layer 4 or the second glass layer 6, and the display film layer 2 can be arranged on the first outer side surface 401 or the first inner side surface 402 of the first glass layer 4, and the display film layer 2 can be arbitrarily arranged on the second outer side surface 601 or the second inner side surface 602 of the second glass layer 6.
[0052] When the display film layer 2 is disposed on the first inner side surface 402 of the first glass layer 4, before the first glass layer 4 and the second glass layer 6 are processed and combined with the interlayer 5, the display film layer 2 is preliminarily disposed on the first inner side surface 402 of the first glass layer 4, and then the first glass layer 4, the second glass layer 6 and the interlayer 5 are processed and combined.
[0053] Similarly, when the display film layer 2 is disposed on the second inner side surface 602 of the second glass layer 6, before the first glass layer 4 and the second glass layer 6 are processed and combined with the interlayer 5, the display film layer 2 is preliminarily disposed on the second inner side surface 602 of the second glass layer 6, and then the first glass layer 4, the second glass layer 6 and the interlayer 5 are processed and combined.
[0054] refer to Figure 2 In some embodiments, the display film layer 2 is disposed on the first outer side surface 401 ; the intermediate layer 3 is disposed on the first outer side surface 401 , and / or the intermediate layer 3 is disposed on the display film layer 2 .
[0055] It can be understood that the vehicle glass 100 is applied to a vehicle, the first glass layer 4 is used as the inner glass of the vehicle facing the inside of the vehicle, and the second glass layer 6 is used as the outer glass of the vehicle facing the outside of the vehicle. The display film layer 2 is directly arranged on the first outer side surface 401 of the first glass layer 4, which is more convenient to arrange, and the display film layer 2 is formed on the inner glass of the vehicle. In actual use, the display film layer 2 will not contact rainwater and dirt outside the vehicle, thereby improving the service life.
[0056] Specifically, the intermediate layer 3 is an adhesive or an adhesion promoter, and the intermediate layer 3 can be pre-arranged on the first outer side surface 401 of the first glass layer 4, and then the display film layer 2 is connected to the intermediate layer 3. Alternatively, the intermediate layer 3 can be pre-arranged on the display film layer 2, and then the display film layer 2 is connected to the first outer side surface 401 of the first glass layer 4 through the intermediate layer 3. Alternatively, the intermediate layer 3 can be arranged on the first outer side surface 401 of the first glass layer 4 and the display film layer 2 at the same time, and then the display film layer 2 is connected to the first glass layer 4, so that the connection is more stable.
[0057] refer to Figure 3 In some embodiments, the display film layer 2 includes a main display layer 201 and an adhesive layer 202 formed on the main display layer 201 .
[0058] It can be understood that the display film layer 2 specifically adopts an LED film screen, and the main display layer 201 is used to realize the power-on display function. The main display layer 201 has a power cord, which is connected to the vehicle's on-board system through the power cord; the adhesive layer 202 has adhesiveness for bonding to the glass substrate 1, that is, the display film layer 2 itself can be quickly assembled with the glass substrate through the adhesive layer 202, thereby improving production efficiency.
[0059] In some embodiments, the intermediate layer 3 is disposed on the glass substrate 1 , and the adhesive layer 202 is bonded to the intermediate layer 3 .
[0060] Specifically, the intermediate layer 3 is an adhesion promoter, which is used for surface pretreatment of some low surface energy materials to increase the initial adhesion during pasting; glass is a low surface energy material, and it is difficult to bond on its surface. Therefore, the intermediate layer 3 is pre-arranged on the first outer side surface 401 to treat the bonding surface of the glass substrate 1, and then the adhesive layer 202 of the display film layer 2 is bonded to the intermediate layer 3, which can effectively improve the adhesion between the display film layer 2 and the glass substrate 1, making the two more firmly bonded and improving product stability. The intermediate layer 3 is preferably a 3M94 adhesion promoter.
[0061] In some embodiments, the outline size of the intermediate layer 3 is configured to be the same as the outline size of the display film layer 2 .
[0062] It can be understood that the outline size of the intermediate layer 3 set on the glass substrate 1 is designed according to the outline size of the display film layer 2; that is, the outline size of the intermediate layer 3 preset on the glass substrate 1 is matched with the outline size of the display film layer 2 that needs to be set on the glass substrate 1, so as to ensure that the display film layer 2 is firmly bonded.
[0063] In some embodiments, the thickness of the display film layer 2 is in the range of 0.1-0.2 mm.
[0064] Specifically, the thickness of the glass substrate 1 of the present application ranges from 4.6 to 5.2 mm, and the thickness of the glass substrate 1 can be any one of 4.6 mm, 4.8 mm, 5 mm, and 5.2 mm. The thickness of the display film layer 2 can be any one of 0.1 mm, 0.12 mm, 0.14 mm, 0.16 mm, 0.18 mm, and 0.2 mm, that is, the thickness of the display film layer 2 is much smaller than the thickness of the glass substrate 1, and the display film layer 2 is difficult to see with the naked eye. The display film layer 2 will not destroy the structure of the glass substrate 1, nor will it affect the overall appearance of the glass substrate 1.
[0065] In some embodiments, the thickness of the intermediate layer 3 is in the range of 5-10 um.
[0066] Specifically, the middle layer 3 is used as a primer and has a very thin texture; the thickness of the middle layer 3 can be any thickness of 5um, 6um, 7um, 8um, 9um, and 10um.
[0067] In some embodiments, the light transmittance of the glass substrate 1 is greater than 70%.
[0068] It is understandable that as automotive glass, the glass substrate 1 needs to have good light transmittance and not affect the display function of the display film layer 2. If the light transmittance is too high, it will cause glare and blindness when driving. The light transmittance of the glass substrate 1 of the present application is configured to be less than 80% to improve driving comfort.
[0069] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
