[0022] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

The meaning of multiple is more than two, greater than, less than, exceed, etc. are understood to exclude the number itself, and above, below, within, etc. are understood to include the number itself.

[0026] In a dimming assembly with multiple optical functional glass panels, the dimming characteristics of the optical functional glass panels located in different locations may vary due to varying user needs. However, generally speaking, users experience optimal comfort when adjacent optical functional glass panels (such as the sunroof and front and rear glass panels, the sunroof and side window panels, or multiple side window panels) have relatively consistent transmittance.

[0027] Based on this, the present application proposes a dimming component and a vehicle, which have at least two optical functional glasses with consistent transmittance in the dark state, thereby improving the user experience.

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

[0029] Specifically, the dimming assembly of the present application is a set of optical functional glass, which is composed of at least two optical functional glasses (optical functional glass 1, optical functional glass 2, ..., optical functional glass N). The dimming assembly is used to be installed on the same vehicle, and different optical functional glasses are installed at different positions of the vehicle. For example, Figure 2 As shown, when the vehicle is a vehicle, the optical functional glass can be installed in at least two positions of the front windshield, front side windows, rear side windows, fixed windows, rear windshield, and sunroof, and each position is used to install a optical functional glass. All optical functional glasses are connected to the control component, and the optical functional glasses are used to adjust to a dark state, a bright state, or other intermediate states under the action of the electric control signal sent by the control component, thereby realizing the dimming function. It is understandable that the optical functional glass can be fully dimmed or partially dimmed. For example, Figure 2 As shown, the front windshield's light-functional glass is local dimming, which requires the visible field of view and can only dim within the sunshade area. The rear side windows and sunroof's light-functional glass, which do not involve the driver's field of view, can therefore dim globally. The front windshield and sunroof are adjacent, and the rear side windows and sunroof are also adjacent.

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

[0031] Among the multiple optical functional glasses of the dimming component of the present application, the difference in the maximum transmittance of any two optical functional glasses is greater than or equal to the first preset difference. In some embodiments, the transmittance of the optical functional glasses can be measured using the GBT 2410-2008 measurement method. 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 understandable 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 maximum 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 understandable 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, but not limited to, different suppliers, different transmittance ranges, and different processes.

[0032] When all the optical functional glasses of the dimming assembly of the present application are in the dark state, the power is cut off between the control assembly and the optical functional glasses. At the same time, in this case, there are at least two optical functional glasses whose transmittance difference in the dark state is less than or equal to the second preset difference. When the transmittance difference of the two optical functional glasses is less than or equal to the second preset difference, the transmittances of the two optical functional glasses are relatively consistent, and the two optical functional glasses exhibit similar optical properties. Generally, the two optical functional glasses are arranged at adjacent installation 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 will be 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 dimming assembly described above, by providing at least two optical functional glasses, each of which has different dimming characteristics, that is, the difference in the maximum transmittance of each of the two optical functional glasses is greater than or equal to a first preset difference. When all optical functional glasses in the dimming assembly are in a dark state, the difference in transmittance of at least two of the optical functional glasses in the dark state is less than or equal to a second preset difference. This ensures consistency in the transmittance of the corresponding two optical functional glasses in the dark state, improving the user experience.

[0034] In one embodiment, the haze of at least one optical functional glass in the bright state is less than or equal to a preset haze. Specifically, haze is a measure of the transparency of optical functional glass, indicating the degree to which light deviates from its 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 this embodiment of the dimming assembly, at least one optical functional glass has a haze less than or equal to a preset haze in the bright state to meet the user's visual requirements for a specific glass installation location. In some embodiments, when the dimming assembly has at least two optical functional glasses, the haze of at least two optical functional glasses in the bright state is less than or equal to the preset haze. In some other embodiments, the haze of all optical functional glasses in the dimming assembly in the bright state is less than or equal to the preset haze, ensuring high clarity of all optical functional glasses in the bright state and ensuring visual quality for users. In some embodiments, the haze of the optical functional glass can be measured using the GBT 2410-2008 measurement method. In some embodiments, the preset haze is between 5% and 15%. In some embodiments, the preset haze is set to 15%. In some embodiments, the preset haze 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 optically functional glasses in the bright state is less than or equal to a third preset difference. Specifically, all optically functional glasses in the dimming assembly of this embodiment have consistent haze performance in the bright state. This configuration provides a more consistent visual experience for the user, improving 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 optically functional glasses in the bright state is less than or equal to a preset haze, and the difference in haze between any two optically functional glasses in the bright state is less than or equal to a third preset difference. Specifically, the dimming assembly in this embodiment ensures high clarity of the optically functional glasses in the bright state while also maintaining consistent haze, further enhancing the user experience.

[0037] In one embodiment, 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 stacked in sequence. Specifically, the structures of the optical functional glasses of the dimming components in this embodiment are all the same, and are all multi-layer composite structures, which include the first glass 111, the first adhesive layer 112, the photoelectric functional film 113, the second adhesive layer 114, and the second glass 115 stacked in sequence. The first glass 111 serves as the outermost protective layer to resist impact, scratches, and chemical corrosion from the external environment, and to provide 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 optoelectronic functional film 113 is a film layer with dimming capabilities, capable of changing its transmittance in response to an electrical control signal. It can be a white polymer dispersed liquid crystal film (PDLC), a dye-polymer dispersed liquid crystal film (D-PDLC), a suspended particle film (SPD), a dye liquid crystal film (LC), or an electrochromic film (EC). The second adhesive layer 114 is used to tightly bond the optoelectronic functional film 113 to the second glass 115, forming a complete composite structure. As the inner layer of the composite structure, the second glass 115 provides additional physical protection and support while maintaining the transparency of the overall structure. In some embodiments, the first adhesive layer 112 and the second adhesive layer 114 can be made of polyvinyl butyral (PVB), polyethylene-polyvinyl acetate copolymer (EVA), or ethylene-methacrylic acid copolymer (SGP). In some embodiments, the thickness and color of the first and second glasses 111 and 115 can be customized based on specific requirements. For example, thicknesses of 2.1 mm white glass, 2 mm white glass, 1.8 mm gray glass, or 1.6 mm gray glass can be used.

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

[0039] In one embodiment, Figure 4As shown, the dimming component includes: a first optical functional glass, a second optical functional glass and a third optical functional glass, and the transmittance difference between the first optical functional glass and the second optical functional glass in the dark state is less than or equal to the second preset difference. Specifically, the dimming component of this embodiment is composed of three optical functional glasses, namely the first optical functional glass, the second optical functional glass and the third optical functional glass, and all of them are in the dark state. The transmittance difference between the first optical functional glass and the second optical functional glass in the dark state is less than or equal to the second preset difference, so that the transmittance of the two optical functional glasses is similar. The transmittance difference between the third optical functional glass and the first optical functional glass or the second optical functional glass in the dark state may 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 can be understood that when the optical functional glass is in the dark state, the control component may not output an electrical signal to the optical functional glass.

[0040] In one embodiment, the optoelectronic functional film 113 of the first optical functional glass is an electrochromic dimming film, the optoelectronic functional film 113 of the second optical functional glass is a dye liquid crystal dimming film, and the optoelectronic functional film 113 of the third optical functional glass is a dye 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 optical functional glass, the second optical functional glass, and the third optical functional glass are identical. Specifically, in this embodiment, the optoelectronic functional film 113 of the first optical functional glass, the second optical functional glass, and the third optical functional glass are made of different materials, but the other film structure materials of the optical functional glass are the same. In the dark state, the transmittance difference between the first optical functional glass and the second optical functional glass meets the requirements.

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

[0042]

[0043] As shown in the table above, in the dark state, the transmittance difference between the first and second optical functional glasses is 0.3%, which is less than the second preset difference (2%). The transmittance difference between the first and third optical functional glasses is 4.5%, and the transmittance difference between the second and third optical functional glasses is 4.2%, both exceeding the second preset difference (2%). The similar transmittance of the first and second optical functional glasses in the dark state enhances the user experience. Furthermore, the haze difference between each of the three optical functional glasses in the bright state is less than the third preset difference (1%), ensuring the clarity of the optical functional glasses in the bright state.

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

[0045] For example, the first optical functional glass is used as the sunroof dimming glass, which uses a suspended particle (SPD) dimming film with a transmittance range of 1.5% to 40%. The second optical functional glass is used as the rear windshield dimming glass, which uses a dye polymer dispersed liquid crystal (D-PDLC) dimming film with a transmittance range of 5% to 37%. The third optical functional glass is used as the front windshield dimming glass, which uses an electrochromic (EC) dimming film with a transmittance range of 0.35% to 8%. In this case, the difference in the maximum transmittance between the first and second optical functional glass is 3%, the difference in the maximum transmittance between the first and third optical functional glass is 32%, and the difference in the maximum transmittance between the second and third optical functional glass is 29%, all exceeding the first preset difference (2%). Therefore, they can be regarded as three different optical functional glasses. The specific product combination parameters are shown in the following table:

[0046]

[0047] As shown in the table above, in the dark state, the transmittance difference between the first and second optical functional glasses is 0.2%, which is less than the second preset difference (0.5%). The transmittance difference between the first and third optical functional glasses is 0.85%, and the transmittance difference between the second and third optical functional glasses is 0.65%, both exceeding the second preset difference (0.5%). The transmittance of the first and second optical functional glasses is similar in the dark state, improving the user experience. Furthermore, the haze difference between each of the three optical functional glasses in the bright state is less than the third preset difference (1.5%), ensuring the clarity of the optical functional glasses in the bright state.

[0048] In one embodiment, the optoelectronic functional film 113 of the first optical functional glass is a dye polymer dispersed liquid crystal dimming film, the optoelectronic functional film 113 of the second optical functional glass is a dye polymer dispersed liquid crystal dimming film, and the optoelectronic 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 the first optical functional glass and the third optical functional glass are respectively identical. Specifically, in this embodiment, the optoelectronic functional film 113 of the first optical functional glass and the second optical functional glass is made of the same material, which is different from the optoelectronic functional film 113 of the third optical functional glass. Moreover, the first glass 111, the first adhesive layer 112, the second adhesive layer 114, and the second glass 115 of the first optical functional glass and the third optical functional glass are all identical. In the dark state, the transmittance difference between the first optical functional glass and the second optical functional glass meets the requirements.

[0049] For example, the first optical functional glass is used as the sunroof dimming glass, which uses a dye polymer dispersed liquid crystal (D-PDLC) dimming film with a transmittance range of 5% to 37%. The second optical functional glass is used as the rear windshield dimming glass, which uses a dye polymer dispersed liquid crystal (D-PDLC) dimming film with a transmittance range of 8% to 50%. The third optical functional glass is used as the front windshield dimming glass, which uses an electrochromic (EC) dimming film with a transmittance range of 0.35% to 8%. In this case, the difference in the maximum transmittance between the first and second optical functional glass is 13%, the difference in the maximum transmittance between the first and third optical functional glass is 29%, and the difference in the maximum transmittance between the second and third optical functional glass is 42%, all exceeding the first preset difference (4%). Therefore, they can be regarded as three different optical functional glasses. The specific product combination parameters are shown in the following table:

[0050]

[0051] As shown in the table above, in the dark state, the transmittance difference between the first and second optical functional glasses is 0.1%, which is less than the second preset difference (1%). The transmittance difference between the first and third optical functional glasses is 1.15%, and the transmittance difference between the second and third optical functional glasses is 1.25%, both exceeding the second preset difference (1%). The similar transmittance of the first and second optical functional glasses in the dark state enhances the user experience. Furthermore, the haze difference between each of the three optical functional glasses in the bright state is less than the third preset difference (4%), ensuring the clarity of the optical functional glasses in the bright state.
