[0002] With the development of smart glass technology, smart glass is increasingly being used in various vehicles.

[0009] In one embodiment, it includes: a first light-functional glass, a second light-functional glass, and a third light-functional glass, wherein the difference in transmittance between the first light-functional glass and the second light-functional glass in the dark state is less than or equal to a second preset difference.

[0010] In one embodiment, the photoelectric functional film of the first optical functional glass is an electrochromic dimming film, the photoelectric functional film of the second optical functional glass is a dye liquid crystal dimming film, and the photoelectric functional film of the third optical functional glass is a dye polymer dispersed liquid crystal dimming film.

[0022] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0026] In dimming systems with multiple light-sensing glass panes, the dimming characteristics of glass panes located in different positions may vary due to different user needs. However, generally speaking, the most comfortable state for users is when adjacent light-sensing glass panes (such as the sunroof and front and rear windows, the sunroof and side windows, or multiple panes of glass in a side window) have a relatively consistent transmittance.

[0027] Based on this, this application proposes a dimming component and a vehicle in which at least two light-functional glass have the same transmittance in the dark state, thereby improving the user experience.

[0028] In one embodiment, such as Figure 1 As shown, this application proposes a dimming component, including: at least two optical functional glasses, wherein the difference in the highest transmittance of any two optical functional glasses is greater than or equal to a first preset difference, and the difference in transmittance of the at least two optical functional glasses in the dark state is less than or equal to a second preset difference, wherein the second preset difference is less than the first preset difference.

[0029] Specifically, the dimming assembly of this application is a set of optical functional glass, comprising at least two optical functional glasses (optical functional glass 1, optical functional glass 2, ..., optical functional glass N). This dimming assembly is used for installation on the same vehicle, with different optical functional glasses installed at different locations on the vehicle. For example, as... Figure 2 As shown, when the vehicle is a vehicle, the light-functional glass can be installed in at least two of the following locations: the windshield, front side windows, rear side windows, fixed windows, rear window, and sunroof, with one light-functional glass pane installed in each location. All light-functional glass panes are connected to a control assembly. The light-functional glass panes are used to adjust to a dark state, a bright state, or other intermediate states under the action of electronic control signals sent by the control assembly, thereby achieving the dimming function. It can be understood that the light-functional glass can provide overall dimming or partial dimming. For example, as... Figure 2 As shown, the windshield's light-adjustable glass is for partial dimming because it requires a visible field of vision, therefore dimming can only be performed within the sunshade area. The rear side windows and sunroof's light-adjustable glass, since they do not affect the driver's field of vision, can therefore be fully dimmed. The windshield and sunroof are adjacent to each other, as are the rear side windows and sunroof.

[0030] The control component is used to send a corresponding electronic control signal to each optical functional glass. After receiving the corresponding electronic control signal, the optical functional glass can switch from the colored state to the faded state and from the faded state to the colored state, or it is not limited to the colored state and the faded state. Under different electronic control signals, it can present a third or even more intermediate optical states.

[0031] In the dimming assembly of this application, the difference in the highest transmittance of any two optical functional glasses is greater than or equal to a first preset difference. In some embodiments, the transmittance of the optical functional glass can be measured using the measurement method of GBT 2410-2008. In some embodiments, the first preset difference is 2% to 4%. In some embodiments, the first preset difference is set to 4%. In some embodiments, the first preset difference is set to 2%. It is understood that since the second preset difference is less than the first preset difference, when the first preset difference is set to 2%, the second preset difference is set to less than 2%. When the difference in the highest transmittance of two optical functional glasses meets the above conditions, the two optical functional glasses can be considered to be different optical functional glasses. It is understood that different optical functional glasses are not limited to different materials; optical functional glasses of the same material may also be considered different optical functional glasses due to differences including, but not limited to, different suppliers, different transmittance ranges, and different manufacturing processes.

[0032] When all the optical functional glass of the dimming component of this application is in a dark state, the power is cut off between the control component and the optical functional glass. Simultaneously, in this situation, the transmittance difference between at least two optical functional glasses in the dark state is less than or equal to a second preset difference. When the transmittance difference between the two optical functional glasses is less than or equal to the second preset difference, the transmittance of the two optical functional glasses is relatively consistent, and the two optical functional glasses exhibit similar optical characteristics. Generally, these two optical functional glasses are installed in adjacent mounting positions in the vehicle. In some embodiments, the second preset difference is less than or equal to 2%. In some embodiments, the second preset difference is set to 1%. In some embodiments, the second preset difference is set to 0.5%. It is understood that when calculating the transmittance difference between the two optical functional glasses in the dark state, the larger transmittance value is subtracted from the smaller transmittance value.

[0033] In the aforementioned dimming component, at least two optical functional glasses are used, and the dimming characteristics of any two optical functional glasses are different, meaning the difference in the maximum transmittance of any two optical functional glasses is greater than or equal to a first preset difference. When all the optical functional glasses of the dimming component are in a dark state, at least two optical functional glasses have a transmittance difference in the dark state that is less than or equal to a second preset difference, thereby ensuring the consistency of the transmittance of the corresponding two optical functional glasses in the dark state and improving the user experience.

[0034] In one embodiment, at least one optical functional glass exhibits a haze level less than or equal to a preset haze level in a bright state. Specifically, haze is an indicator of the transparency of optical functional glass, representing the degree to which light deviates from the incident direction due to scattering within or on the surface of the optical functional glass. The lower the haze value, the more transparent the optical functional glass and the clearer the visual effect. In the dimming assembly of this embodiment, at least one optical functional glass exhibits a haze level less than or equal to the preset haze level in a bright state to meet the user's visual effect requirements for a specific glass installation location. In some embodiments, when the dimming assembly contains at least two optical functional glasses, at least two of the optical functional glasses exhibit a haze level less than or equal to the preset haze level in a bright state. In some other embodiments, all the optical functional glasses of the dimming assembly exhibit a haze level less than or equal to the preset haze level in a bright state, ensuring high clarity of all the optical functional glasses in a bright state and guaranteeing a good visual effect for the user. In some embodiments, the haze level of the optical functional glass can be measured using the measurement method of GBT 2410-2008. In some embodiments, the preset haze level is 5% to 15%. In some embodiments, the preset haze level is set to 15%. In some embodiments, the preset haze level is set to 10%. In some embodiments, the preset haze is set to 5%.

[0035] In one embodiment, the difference in haze between any two optical functional glasses in the bright state is less than or equal to a third preset difference. Specifically, all optical functional glasses of the dimming assembly in this embodiment have consistent haze performance in the bright state. This setting makes the user's visual effect more consistent and improves the user experience. In some embodiments, the third preset difference is less than or equal to 3%. In some embodiments, the third preset difference is set to 2%. In some embodiments, the third preset difference is set to 1%.

[0036] In one embodiment, the haze of all optical functional glass in the bright state is less than or equal to a preset haze, and the difference in haze between any two optical functional glass in the bright state is less than or equal to a third preset difference. Specifically, the dimming component in this embodiment maintains consistent haze while ensuring high clarity of the optical functional glass in the bright state, further enhancing the user experience.

[0037] In one embodiment, such as Figure 3As shown, the optical functional glass includes a first glass 111, a first adhesive layer 112, a photoelectric functional film 113, a second adhesive layer 114, and a second glass 115, which are stacked sequentially. Specifically, the optical functional glass structures of the dimming components in this embodiment are all the same, and are all multi-layer composite structures, including a first glass 111, a first adhesive layer 112, a photoelectric functional film 113, a second adhesive layer 114, and a second glass 115, which are stacked sequentially. The first glass 111 serves as the outermost protective layer, used to resist impacts, scratches, and chemical corrosion from the external environment, providing physical protection for the internal photoelectric functional film 113 and other film layers. The first adhesive layer 112 is used to tightly bond the first glass 111 and the photoelectric functional film 113 together to form a stable composite structure. The photoelectric functional film 113 is a film layer with dimming capability. Under the action of an electronically controlled signal, it can change its transmittance. The photoelectric functional film 113 can be one of the following: white polymer-dispersed liquid crystal film (PDLC), dye-dispersed polymer liquid crystal film (D-PDLC), suspended particle film (SPD), dye liquid crystal film (LC), or electrochromic film (EC). The second adhesive layer 114 is used to tightly bond the photoelectric functional film 113 to the second glass 115 to form a complete composite structure. The second glass 115, as the inner layer of the composite structure, provides additional physical protection and support while maintaining the overall transparency of the structure. In some embodiments, the first adhesive layer 112 and the second adhesive layer 114 can be one of polyvinyl butyral (PVB), polyethylene-vinyl acetate copolymer (EVA), or ethylene-methacrylic acid copolymer (SGP). In some embodiments, the thickness and color of the first glass 111 and the second glass 115 can be set according to specific parameter requirements. For example, it can be 2.1mm white glass, 2mm white glass, 1.8mm gray glass, 1.6mm gray glass, etc.

[0038] In one embodiment, such as Figure 3 As shown, the optical functional glass further includes an edge-filling adhesive layer 116, through which the photoelectric functional film 113 is disposed between the first adhesive layer 112 and the second adhesive layer 114. Specifically, this embodiment further includes an edge-filling adhesive layer 116 to fill and fix the edges of the photoelectric functional film 113, preventing gaps or displacement between the photoelectric functional film 113 and the adhesive layer, while enhancing the edge sealing of the composite structure. In some embodiments, the edge-filling adhesive layer 116 may be one of polyvinyl butyral (PVB), polyethylene-polyvinyl acetate copolymer (EVA), or ethylene-methacrylic acid copolymer (SGP).

[0039] In one embodiment, such as Figure 4As shown, the dimming component includes a first light-functional glass, a second light-functional glass, and a third light-functional glass. The transmittance difference between the first and second light-functional glasses in the dark state is less than or equal to a second preset difference. Specifically, the dimming component in this embodiment consists of three light-functional glasses, namely the first, second, and third light-functional glasses, all of which are in the dark state. The transmittance difference between the first and second light-functional glasses in the dark state is less than or equal to the second preset difference, thereby making the transmittance of the two light-functional glasses similar. The transmittance difference between the third light-functional glass and the first or second light-functional glass in the dark state can be greater than, equal to, or less than the second preset difference, which is not limited here, and is used to meet different usage requirements. It is understood that when the light-functional glasses are in the dark state, the control component may not output electrical signals to the light-functional glasses.

[0040] In one embodiment, the photoelectric functional film 113 of the first optical functional glass is an electrochromic color-changing film, the photoelectric functional film 113 of the second optical functional glass is a dye-based liquid crystal dimming film, and the photoelectric functional film 113 of the third optical functional glass is a dye-based polymer-dispersed liquid crystal dimming film. The first glass 111, the first adhesive layer 112, the second adhesive layer 114, and the second glass 115 of the first, second, and third optical functional glasses are all identical in pairs. Specifically, in this embodiment, the materials of the photoelectric functional films 113 of the first, second, and third optical functional glasses are all different, but the materials of the other film layer structures of the optical functional glasses are the same. In the dark state, the transmittance difference between the first and second optical functional glasses meets the requirements.

[0041] For a specific example, the first optical functional glass is used as the front windshield dimming glass, employing an electrochromic (EC) dimming film with a transmittance ranging from 0.35% to 12%. The second optical functional glass is used as the rear side window dimming glass, employing a dye-liquid crystal (LC) dimming film with a transmittance ranging from 0.8% to 17%. The third optical functional glass is used as the front side window dimming glass, employing a dye-polymer dispersed liquid crystal (D-PDLC) dimming film with a transmittance ranging from 5% to 37%. In this case, the difference in the maximum transmittance between the first and second optical functional glasses is 5%, the difference between the first and third optical functional glasses is 25%, and the difference between the second and third optical functional glasses is 20%, all exceeding the first preset difference (4%). Therefore, they can be considered as three different optical functional glasses, and their specific product combination parameters are shown in the table below:

[0042]

[0043] As shown in the table above, in the dark, the transmittance difference between the first and second light-functioning glass is 0.3%, which is less than the second preset difference (2%). The transmittance difference between the first and third light-functioning glass is 4.5%, and the transmittance difference between the second and third light-functioning glass is 4.2%, both of which are greater than the second preset difference (2%). The transmittance of the first and second light-functioning glass is similar in the dark, improving the user experience. Furthermore, the haze difference between any two of the three light-functioning glass panes in the bright state is less than the third preset difference (1%), ensuring the clarity of the light-functioning glass in the bright state.

[0044] In one embodiment, the photoelectric functional film 113 of the first optical functional glass is a suspended particle dimming film, the photoelectric functional film 113 of the second optical functional glass is a dye polymer dispersed liquid crystal dimming film, and the photoelectric functional film 113 of the third optical functional glass is an electrochromic dimming film. The first glass 111, the first adhesive layer 112, the second adhesive layer 114, and the second glass 115 of both the first and third optical functional glasses are identical. Specifically, the materials of the photoelectric functional films 113 of the first, second, and third optical functional glasses in this embodiment are all different, but the first glass 111, the first adhesive layer 112, the second adhesive layer 114, and the second glass 115 of both the first and third optical functional glasses are identical. In the dark state, the transmittance difference between the first and second optical functional glasses meets the requirements.

[0045] For a specific example, the first light-functional glass is used as the skylight dimming glass, employing a suspended particle (SPD) dimming film with a transmittance ranging from 1.5% to 40%. The second light-functional glass is used as the rear window dimming glass, employing a dye-polymer dispersed liquid crystal (D-PDLC) dimming film with a transmittance ranging from 5% to 37%. The third light-functional glass is used as the front window dimming glass, employing an electrochromic (EC) dimming film with a transmittance ranging from 0.35% to 8%. In this case, the difference in the maximum transmittance between the first and second light-functional glass is 3%, the difference between the first and third light-functional glass is 32%, and the difference between the second and third light-functional glass is 29%, all exceeding the first preset difference (2%). Therefore, it can be considered as three different light-functional glasses, and their specific product combination parameters are shown in the table below:

[0046]

[0047] As shown in the table above, in the dark, the transmittance difference between the first and second light-functioning glass is 0.2%, which is less than the second preset difference (0.5%). The transmittance difference between the first and third light-functioning glass is 0.85%, and the transmittance difference between the second and third light-functioning glass is 0.65%, both of which are greater than the second preset difference (0.5%). The transmittance of the first and second light-functioning glass is similar in the dark, improving the user experience. Furthermore, the haze difference between any two of the three light-functioning glass panes in the bright state is less than the third preset difference (1.5%), ensuring the clarity of the light-functioning glass in the bright state.

[0048] In one embodiment, the photoelectric functional film 113 of the first optical functional glass is a dye-polymer dispersed liquid crystal dimming film, the photoelectric functional film 113 of the second optical functional glass is a dye-polymer dispersed liquid crystal dimming film, and the photoelectric functional film 113 of the third optical functional glass is an electrochromic dimming film. The first glass 111, the first adhesive layer 112, the second adhesive layer 114, and the second glass 115 of both the first and third optical functional glasses are identical in pairs. Specifically, in this embodiment, the photoelectric functional films 113 of the first and second optical functional glasses are made of the same material, but not the same material as the photoelectric functional film 113 of the third optical functional glass. Furthermore, the first glass 111, the first adhesive layer 112, the second adhesive layer 114, and the second glass 115 of both the first and third optical functional glasses are identical. In the dark state, the transmittance difference between the first and second optical functional glasses meets the requirements.

[0049] For a specific example, the first light-functional glass is used as the skylight dimming glass, employing a dye-polymer dispersed liquid crystal (D-PDLC) dimming film with a transmittance ranging from 5% to 37%. The second light-functional glass is used as the rear window dimming glass, employing a D-PDLC dimming film with a transmittance ranging from 8% to 50%. The third light-functional glass is used as the front window dimming glass, employing an electrochromic (EC) dimming film with a transmittance ranging from 0.35% to 8%. In this case, the difference in maximum transmittance between the first and second light-functional glass is 13%, the difference between the first and third light-functional glass is 29%, and the difference between the second and third light-functional glass is 42%, all exceeding the first preset difference (4%). Therefore, it can be considered as three different light-functional glasses, and their specific product combination parameters are shown in the table below:

[0050]

[0051] As shown in the table above, in the dark, the transmittance difference between the first and second light-functioning glass is 0.1%, which is less than the second preset difference (1%). The transmittance difference between the first and third light-functioning glass is 1.15%, and the transmittance difference between the second and third light-functioning glass is 1.25%, both of which are greater than the second preset difference (1%). The transmittance of the first and second light-functioning glass is similar in the dark, improving the user experience. Furthermore, the haze difference between any two of the three light-functioning glass panes in the bright state is less than the third preset difference (4%), ensuring the clarity of the light-functioning glass in the bright state.
