[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.

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 that can control the transmittance of different optical functional glasses to be consistent, 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, or the transmittance chromatic aberration of any two optical functional glasses is greater than or equal to a second preset difference, and the transmittance difference of any two optical functional glasses under the action of corresponding target electrical control signals is less than or equal to a third 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 their transmittance 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 2As 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 in the dimming assembly of the present application, the difference in the maximum transmittance of any two optical functional glasses is greater than or equal to a first preset difference, or the color difference in transmission between any two optical functional glasses is greater than or equal to a second 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 color difference of the optical functional glasses can be measured using the GBT 7921-2008 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%. In some embodiments, the second preset difference is 2 to 5%. In some embodiments, the second preset difference is set to 5. In some embodiments, the second preset difference is set to 2. When the difference in the maximum transmittance or the color difference in transmission between two optical functional glasses meets the above conditions, the two optical functional glasses are considered different. It should be understood that different optical functional glasses are not limited to different materials. Optical functional glasses of the same material can also be considered different due to, but not limited to, different suppliers, different transmittance ranges, or different manufacturing processes.

[0032] When the dimming component of the present application is in operation, the control component will send a preset target electrical control signal to the corresponding optical functional glass. The transmittance difference between any two optical functional glasses under the action of the corresponding target electrical control signal is less than or equal to a third preset difference. When the transmittance difference between the two optical functional glasses is less than or equal to the third preset difference, the transmittance of the two optical functional glasses is relatively consistent, and the two optical functional glasses exhibit similar optical properties. In some embodiments, the third preset difference is less than or equal to 2%. In some embodiments, the third preset difference is set to 1%. In some embodiments, the third preset difference is set to 0.5%. It will be understood that when calculating the transmittance difference between two optical functional glasses, the larger transmittance value is subtracted from the smaller transmittance value.

[0033] In the dimming assembly described above, at least two optical functional glasses are provided, and the dimming characteristics of any two of the provided optical functional glasses are different. Specifically, the difference in the maximum transmittance of any two optical functional glasses is greater than or equal to a first preset difference, or the chromatic aberration of the transmittance of any two optical functional glasses is greater than or equal to a second preset difference. During use, the transmittance difference between any two optical functional glasses under the influence of corresponding target electrical control signals is controlled to be less than or equal to a third preset difference, thereby ensuring consistent transmittance across all optical functional glasses and 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 fourth 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 fourth preset difference is less than or equal to 3%. In some embodiments, the fourth preset difference is set to 2%. In some embodiments, the fourth 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 fourth preset difference. Specifically, the dimming assembly in this embodiment maintains haze consistency while ensuring high clarity of the optically functional glasses in the bright state, further enhancing the user experience.

[0037] In one embodiment, Figure 3 As 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 can serve as the outermost protective layer to resist impact, scratches, and chemical corrosion from the external environment, and 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. The second glass 115 serves as the inner layer of the composite structure, providing 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, by which the photovoltaic functional film 113 is secured 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 assembly includes: a first optical functional glass and a second optical functional glass. The difference between the transmittance of the first optical functional glass under the influence of a first electrical control signal and the transmittance of the second optical functional glass under the influence of a second electrical control signal is less than or equal to a third preset difference. Specifically, the dimming assembly of this embodiment comprises two optical functional glasses, namely the first optical functional glass and the second optical functional glass. The difference between the transmittance of the first optical functional glass under the influence of the first electrical control signal and the transmittance of the second optical functional glass under the influence of the second electrical control signal is less than or equal to the third preset difference, thereby making the transmittances of the two optical functional glasses similar.

[0040] It is understood that since the first and second optically functional glasses are different optically functional glasses, the electronic control logics of the first and second electronic control signals are generally different. The difference in electronic control logic can be due to different input characteristics, such as the difference between DC and AC power supply characteristics; or, when the input characteristics are the same, different frequencies, such as 50Hz and 120Hz. In some embodiments, the electronic control logic differs when the frequency difference is greater than or equal to 5Hz; or, when the input characteristics and frequency are the same, the voltage magnitudes differ, such as 24V and 60V. In some embodiments, the electronic control logic differs when the voltage difference is greater than or equal to 2V; or, when the input characteristics, frequency, and voltage are the same, the waveforms differ, such as a sine wave and a square wave; or, when the input characteristics are the same, the open circuit voltage (OCV) differs, such as 0.1V and 0.3V. In some embodiments, the electronic control logic differs when the open circuit voltage difference is greater than or equal to 0.1V.

[0041] In some embodiments, the photoelectric functional film 113 with a rated response time of greater than 30 seconds per square meter at 23°C is driven by a DC power supply. In some embodiments, the DC voltage is less than or equal to 2V. In some embodiments, the DC voltage is less than or equal to 1.5V. In some embodiments, the photoelectric functional film 113 with a rated response time of less than 30 seconds per square meter at 23°C is driven by an AC power supply. In some embodiments, the AC voltage is less than 110V. In some embodiments, the AC voltage is less than 60V. In some embodiments, the AC voltage is less than 24V.

[0042] In one embodiment, the optoelectronic functional films 113 of the first and second optical functional glasses are both electrochromic color-shifting films. The first glass 111, first adhesive layer 112, second adhesive layer 114, and second glass 115 of the first and second optical functional glasses are identical. The first and second electrical control signals are both DC signals, and the first and second electrical control signals have different open-circuit voltages. Specifically, in this embodiment, the optoelectronic functional films 113 of the first and second optical functional glasses are made of the same material, and the other film layer structures of the optical functional glasses are also identical. These films are controlled by DC control signals with different open-circuit voltages, thereby ensuring that the transmittance or color difference of the first and second optical functional glasses meet the requirements.

[0043] For example, the first optical functional glass is used as sunroof dimming glass, using an electrochromic (EC) dimming film with a transmittance range of 0.2% to 8%. The second optical functional glass is used as rear side window dimming glass, using an electrochromic (EC) dimming film with a transmittance range of 0.32% to 13%. The electrochromic functional film 113 made of EC material uses OCV as the electronic control logic. Although the electrochromic functional film 113 of both optical functional glasses is made of EC material, the difference in their maximum transmittance is 5%, which exceeds the first preset difference (4%). Therefore, they can be considered two different optical functional glasses. The specific product combination parameters are shown in the following table:

[0044]

[0045] As shown in the table above, the first dimming glass located at the sunroof position and the second dimming glass located at the rear side window position, in three different states, adjust the open-circuit voltage of their first and second electronic control signals to achieve corresponding transmittance differences of 0.1%, 0.2%, and 0.4%, respectively. These are all less than the third preset difference (2%). The transmittance of the two dimming glasses is similar, improving the user experience.

[0046] In one embodiment, the optoelectronic functional film 113 of the first optical functional glass is an electrovariable dimming film, and the optoelectronic functional film 113 of the second optical functional glass is a dye liquid crystal dimming film. The first glass 111, first adhesive layer 112, second adhesive layer 114, and second glass 115 of the first and second optical functional glasses are identical. The first electrical control signal is a DC signal, and the second electrical control signal is an AC signal. Specifically, in this embodiment, the optoelectronic functional films 113 of the first and second optical functional glasses are made of different materials, but the other film layer structures of the optical functional glasses are identical. The electrovariable dimming film of the first optical functional glass is controlled using a DC signal, while the dye liquid crystal dimming film of the second optical functional glass is controlled using an AC signal, thereby ensuring that the transmittance or color difference of the first and second optical functional glasses meet the requirements.

[0047] For example, the first optical functional glass is used as sunroof dimming glass, employing an electrochromic (EC) dimming film with a transmittance range of 0.2% to 8%. The second optical functional glass is used as rear side window dimming glass, employing a liquid crystal (LC) dimming film with a transmittance range of 0.8% to 17%. The EC photoelectric functional film 113 uses OCV as the electrical control logic, while the LC photoelectric functional film 113 uses AC voltage as the electrical control logic. The difference in the maximum transmittance of the two optical functional glasses is 9%, exceeding the first preset difference (4%). Therefore, they can be considered two different optical functional glasses. The specific product combination parameters are shown in the following table:

[0048]

[0049] As shown in the table above, the first dimming glass located at the sunroof and the second dimming glass located at the rear side windows have transmittance differences of 0.4% and 0.8%, respectively, in two different states, by adjusting the electrical control logic of their first and second electrical control signals. Both are less than the third preset difference (2%). The transmittance of the two dimming glasses is similar, improving the user experience.

[0050] In one embodiment, the optoelectronic functional film 113 of the first optical functional glass is a dye polymer dispersed liquid crystal dimming film, and the optoelectronic functional film 113 of the second optical functional glass is a dye liquid crystal dimming film. The first glass 111 and the second glass 115 of the first optical functional glass and the second optical functional glass are different. The first electrical control signal and the second electrical control signal are both AC signals, and the voltages of the first electrical control signal and the second electrical control signal are different. Specifically, in this embodiment, the optoelectronic functional film 113 of the first optical functional glass and the second optical functional glass are made of different materials, and the first glass 111 and the second glass 115 of the optical functional glass are also different. The dye polymer dispersed liquid crystal dimming film of the first optical functional glass is controlled using an AC signal, and the dye liquid crystal dimming film of the second optical functional glass is also controlled using an AC signal, so that the transmittance or color difference of the first optical functional glass and the second optical functional glass meet the requirements.

[0051] For example, the first optical functional glass is used as sunroof dimming glass, employing a dye-polymer dispersed liquid crystal (D-PDLC) dimming film with a transmittance range of 5% to 35%. The second optical functional glass is used as rear side window dimming glass, employing a dye-liquid crystal (LC) dimming film with a transmittance range of 0.8% to 17%. Both the D-PDLC and LC photoelectric functional films 113 use AC voltage as their electrical control logic, but the AC voltages differ. The difference in the maximum transmittance of the two optical functional glass types is 18%, exceeding the first preset difference (4%). Therefore, they can be considered two different optical functional glass types. The specific product combination parameters are shown in the following table:

[0052]

[0053] As shown in the table above, under certain conditions, the first dimming glass located at the sunroof position and the second dimming glass located at the rear side window position adjust the electronic control logic of their first electronic control signals and second electronic control signals to achieve a corresponding transmittance difference of 0.1%, which is less than the third preset difference (2%). This ensures that the transmittance of the two dimming glasses is similar, improving the user experience.

[0054] In one embodiment, the optoelectronic functional film 113 of the first optical functional glass is a dye polymer dispersed liquid crystal dimming film, and the optoelectronic functional film 113 of the second optical functional glass is an electro-variable dimming film. The first glass 111 and the second glass 115 of the first optical functional glass and the second optical functional glass are different. The first electrical control signal is an AC signal, and the second electrical control signal is a DC signal. Specifically, in this embodiment, the optoelectronic functional film 113 of the first optical functional glass and the second optical functional glass are made of different materials, and the first glass 111 and the second glass 115 of the optical functional glass are also different. The dye polymer dispersed liquid crystal dimming film of the first optical functional glass is controlled using an AC signal, and the electro-variable dimming film of the second optical functional glass is controlled using a DC signal, so that the transmittance or color difference of the first optical functional glass and the second optical functional glass meet the requirements.

[0055] For example, the first optical functional glass is used as sunroof dimming glass, employing a dye-dispersed liquid crystal (D-PDLC) dimming film with a transmittance range of 5% to 35%. The second optical functional glass is used as rear side window dimming glass, employing an electrochromic (EC) dimming film with a transmittance range of 0.3% to 13%. The D-PDLC photoelectric functional film 113 uses AC voltage as its electrical control logic, while the EC photoelectric functional film 113 uses DC voltage as its electrical control logic. The difference in the maximum transmittance of the two optical functional glass types is 22%, exceeding the first preset difference (4%). Therefore, they can be considered two different optical functional glass types. The specific product combination parameters are shown in the following table:

[0056]

[0057] As shown in the table above, under certain conditions, the first dimming glass located at the sunroof and the second dimming glass located at the rear side windows adjust the electrical control logic of their first and second electrical control signals to achieve a corresponding transmittance difference of 0.9%, which is less than the third preset difference (2%). This results in similar transmittances for the two dimming glasses, improving the user experience.
