window assembly and vehicle

[0001] This application claims priority to Chinese Patent Application No. 202411222013.3, filed with the China National Intellectual Property Administration on August 30, 2024, entitled "Window Assembly and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of intelligent vehicle technology, and more specifically, to a window assembly and a vehicle. Background Technology

[0003] To enhance cabin privacy, users can apply window tint to their car windows. However, window tinting limits the light transmittance of a portion of the windows to a fixed value, which may not be beneficial for users in certain situations. Summary of the Invention

[0004] This application provides a window assembly and a vehicle. By coordinating the light transmission performance of each layer in the window assembly, it can effectively meet the usage needs of the window assembly in different scenarios even when the dimming performance of the dimming element is limited.

[0005] In a first aspect, a vehicle window assembly is provided. The vehicle window assembly includes a first glass body, a second glass body, a dimming element, a first interlayer, and a second interlayer. The dimming element is disposed in a first region of the vehicle window assembly; in the thickness direction of the vehicle window assembly, the dimming element is located between the first glass body and the second glass body; the dimming element is bonded to the first glass body through the first interlayer and to the second glass body through the second interlayer.

[0006] The window assembly meets the following conditions: 1.1) The first and second glass bodies are transparent glass; 1.2) The light transmittance of the first and second glass bodies in the visible light band is greater than 83% and less than 93%; 1.3) The light transmittance of the first and second intermediate layers in the visible light band is greater than or equal to 85%; 1.4) The light transmittance of the dimming element in the visible light band can be adjusted within an adjustable range, where the first light transmittance is the maximum value of the adjustable range and the second light transmittance is the minimum value of the adjustable range; wherein the first light transmittance is greater than or equal to 12% and the second light transmittance is less than or equal to 0.6%.

[0007] For example, taking the window assembly 100 as an example, the first glass body can be one of glass bodies 110 and 120, and the second glass body can be the other of glass bodies 110 and 120; the first intermediate layer can be one of intermediate layers 140 and 150, and the second intermediate layer can be the other of intermediate layers 140 and 150.

[0008] In this application, by coordinating the light transmission performance of each layer in the window assembly, the use needs of the window assembly in different scenarios can be effectively met even when the dimming performance of the dimming element is limited.

[0009] In some possible implementations, the window assembly (100) may also include a third intermediate layer (160), which may be disposed in the outer periphery of the first region. The third intermediate layer (160) may be used to bond the first glass body (110) and the second glass body (120); the third intermediate layer (160) may form a receiving space with the first glass body (110) and the second glass body (120); the receiving space may be used to accommodate a sandwich structure composed of the first intermediate layer (140), the dimming element (130), and the second intermediate layer (150).

[0010] In this application, the amount of water, oxygen, dust, and other substances that intrude into the area where the dimming element is located can be reduced through the cooperation of multiple intermediate layers; by using a narrower third intermediate layer, interference from water, oxygen, and other substances to the dimming element can be avoided. This method helps to reduce the width of the shielding layer, thereby reducing the degradation of the vehicle's appearance caused by the installation of the dimming element.

[0011] In some possible implementations, the first surface of the first glass body (110) and / or the second glass body (120) may be provided with a shielding layer (171, 172). The end of the shielding layer (171, 172) away from the first region may correspond to the end of the peripheral region, and the end of the shielding layer (171, 172) near the first region may correspond to the end of the dimming element (130).

[0012] In this application, by setting a masking layer, an aesthetic effect can be achieved.

[0013] In some possible implementations, the dimming element (130) may include a main body portion (131) and an adhesive tape assembly (132). The main body portion (131) may include a second surface (1311) and a third surface (1312) disposed opposite to each other; the second surface (1311) may be bonded to a first intermediate layer (150), and the third surface (1312) may be bonded to a second intermediate layer (160). A first end of the adhesive tape assembly (132) may be bonded to the second surface (1311), a second end of the adhesive tape assembly (132) may be bonded to the third surface (1312), and a middle portion of the adhesive tape assembly (132) may be bonded to a side of the main body portion (131).

[0014] In this application, by setting an adhesive tape assembly, it is possible to further prevent substances such as water, oxygen, and dust from entering the dimming element from the side, and to further improve the water resistance and oxygen resistance of the window assembly.

[0015] In some possible implementations, the tape assembly (132) may include a plurality of tapes, with two adjacent tapes bonded to each other. The plurality of tapes may include a first tape (1321) and a second tape (1322); a first end of the tape assembly (132) may belong to the first tape (1321), and a second end of the tape assembly (132) may belong to the second tape (1322).

[0016] In some possible implementations, the dimming element (130) may include electrodes, and the window assembly (100) may also include a wiring harness assembly (135). The wiring harness assembly (135) may include a flexible printed circuit board (FPC); the FPC may be connected to the electrodes of the dimming element (130); one end of the FPC near the dimming element (130) may be disposed between the first glass body (110) and the second glass body (120).

[0017] Because flexible circuit boards are thin and easily deformable, this application uses a flexible circuit board to connect to the electrodes of the dimming element, thus avoiding damage to the glass body caused by the portion of the wiring harness assembly located between the two glass bodies.

[0018] In some possible implementations, the window assembly (100) may also include a wiring harness fixing assembly (180); the wiring harness fixing assembly (180) may be disposed on the inner surface of the window assembly (100), and the end of the FPC away from the dimming element (130) may be connected to the wiring harness fixing assembly (180).

[0019] For certain types of vehicle window assemblies, repeated raising and lowering may occur during use. In this application, the wiring harness fixing assembly is disposed on the inner surface of the vehicle window assembly (i.e., the surface of the vehicle window assembly facing the cabin), and the FPC is disposed on the wiring harness fixing assembly, which helps to improve the service life of the wiring harness assembly.

[0020] In some possible implementations, the dimming element (130) includes an electrochromic (EC) film.

[0021] In this application, EC film is used as a dimming element. On the one hand, its dimming rate can achieve a wide adjustable range; on the other hand, its bright state, dark state and intermediate state are all neutral colors, which will not cause the scene observed by the user to have color deviation from the actual scene, nor will it bring the user an additional sense of oppression and restraint.

[0022] In some possible implementations, the transmittance of the first glass body (110) and the second glass body (120) in the visible light band can be greater than 88% and less than or equal to 92%. The transmittance of the first intermediate layer (140) and the second intermediate layer (150) in the visible light band can be greater than or equal to 88%. The first transmittance can be greater than or equal to 14% and less than 17%; the second transmittance can be greater than 0.3% and less than or equal to 0.5%.

[0023] In this application, by further controlling the performance of each component, it is possible to ensure that the window assembly has consistent light transmission performance in mass production.

[0024] In some possible implementations, within a first temperature range, a first transmittance is greater than or equal to 12%, and a second transmittance is less than or equal to 0.6%; the first temperature range may include -10 degrees Celsius to 50 degrees Celsius.

[0025] Secondly, a control method is provided. This method can be executed by a control device of a window assembly with dimming function, or by a component of the control device (such as a chip, processor, processing circuit, etc.), or by a system or vehicle containing the control device.

[0026] The method includes: acquiring dimming indication information; and controlling the light transmittance of the window assembly in the visible light band based on the dimming indication information.

[0027] For example, the window assembly can be the window assembly described in the first aspect above and any possible implementation thereof; or it can be other window assemblies with dimming function.

[0028] In some possible implementations, the dimming indication information can be used to indicate the rotation direction of the dimming knob and the duration of rotation in that direction. Controlling the transmittance of the window assembly in the visible light band based on the dimming indication information can include adjusting the light transmittance of the window assembly in the visible light band according to the rotation direction and the duration.

[0029] For example, the window assembly may include a dimming element whose transmittance in the visible light band is adjustable within an adjustable range, wherein a first transmittance is the maximum value of the adjustable range and a second transmittance is the minimum value of the adjustable range.

[0030] In some possible implementations, adjusting the light transmittance of the window assembly in the visible light band according to the rotation direction and duration may include: adjusting the light transmittance of the dimming element in the visible light band to a first light transmittance when the rotation direction is a first direction and the duration is greater than or equal to a first threshold; or, adjusting the light transmittance of the dimming element in the window assembly in the visible light band to a second light transmittance when the rotation direction is a second direction and the duration is greater than or equal to a second threshold.

[0031] In this application, based on the rotation direction of the dimming knob and the duration of rotation in that direction, the light transmittance of the window assembly can be directly adjusted to the maximum or minimum value, which simplifies the user's process of adjusting the light transmittance.

[0032] In some possible implementations, the dimming instruction information may include first control information, which may be used to instruct the light transmittance of the dimming element to be adjusted to a first light transmittance or a second light transmittance. Controlling the light transmittance of the window assembly in the visible light band according to the dimming instruction information may include: adjusting the light transmittance of the dimming element in the visible light band to a first light transmittance or a second light transmittance according to the first control information.

[0033] In this application, the transmittance can be adjusted to the maximum or minimum value with one click based on the first operation information, which helps to simplify the user's process of adjusting the transmittance.

[0034] In some possible implementations, the dimming indication information can be used to indicate the ambient temperature of the window assembly. Controlling the light transmittance of the window assembly in the visible light band based on the dimming indication information may include: adjusting the light transmittance of the window assembly in the visible light band according to the ambient temperature; and / or, determining adjustment parameters for the light transmittance of the window assembly in the visible light band according to the ambient temperature.

[0035] In this application, adjusting the light transmittance and / or the light transmittance adjustment parameters of the window assembly according to the ambient temperature is beneficial to ensuring the dimming performance and service life of the window assembly.

[0036] Among some possible implementations, determining the adjustment parameters of the window assembly in the visible light band based on the ambient temperature may include: when the ambient temperature is within a first temperature range, using a first value as the ratio of a first light transmittance to a second light transmittance; or, within a second temperature range, using a second value as the ratio of a first light transmittance to a second light transmittance.

[0037] In this application, different ratios are set for the first transmittance and the second transmittance in different temperature ranges, which helps to ensure the service life of the dimming element while meeting the usage requirements.

[0038] In some possible implementations, determining the adjustment parameters of the window assembly in the visible light band based on the ambient temperature may include: setting a first light transmittance to a range greater than or equal to 13% and less than 15% when the ambient temperature is within a first temperature range, and setting a second light transmittance to a range greater than 0.25% and less than or equal to 0.45%; setting a first light transmittance to a range greater than or equal to 9% and less than 11% when the ambient temperature is within a second temperature range, and setting a second light transmittance to a range greater than 0.4% and less than or equal to 0.6%; or setting a first light transmittance to a range greater than or equal to 6% and less than 8% when the ambient temperature is within a third temperature range, and setting a second light transmittance to a range greater than 0.25% and less than or equal to 0.45%.

[0039] In this application, different values ​​are set for the first and second transmittance within different temperature ranges, which helps to ensure the service life of the dimming element while meeting usage requirements.

[0040] In some possible implementations, the first temperature range may include a temperature range from -10 degrees Celsius to 50 degrees Celsius; the second temperature range may include a temperature range from 50 degrees Celsius to 65 degrees Celsius; and the third temperature range may include a temperature range from -20 degrees Celsius to -10 degrees Celsius.

[0041] In some possible implementations, the window assembly is in a first light-transmitting position. Adjusting the light transmittance of the window assembly in the visible light band according to the ambient temperature can include: when the ambient temperature changes from a first ambient temperature to a second ambient temperature, adjusting the light transmittance of the window assembly in the visible light band from a third light transmittance to a fourth light transmittance. Specifically, at the first ambient temperature, the first light transmittance corresponds to the third light transmittance; at the second ambient temperature, the first light transmittance corresponds to the fourth light transmittance.

[0042] In this application, by adjusting the light transmittance, the window assembly can be maintained at a certain light transmittance level even if the ambient temperature changes, thus achieving the effect of maintaining the light transmittance level.

[0043] In some possible implementations, the dimming instruction information may include cabin mode information. Controlling the light transmittance of the window assembly (100) in the visible light band according to the dimming instruction information may include: adjusting the light transmittance of the window assembly (100) in the visible light band according to the cabin mode information, or limiting the adjustment of the light transmittance of the window assembly.

[0044] In this application, the light transmittance of the window assembly is controlled according to the cockpit mode, which can realize the linkage between the light transmittance state of the window assembly and the cockpit mode, thus enriching the user experience.

[0045] Thirdly, a method for preparing a vehicle window assembly is provided. The method includes: disposing a first intermediate layer (140) and a second intermediate layer (150) on two opposing surfaces of a dimming element (130) to form a sandwich structure; disposing a first glass body (110) and a second glass body (120) on two opposing surfaces of the sandwich structure, and placing the sandwich structure in a first region of the first and second glass bodies to obtain a sandwich glass assembly; disposing a sealing sleeve around the sandwich glass assembly; under a first environmental condition, vacuuming the sandwich glass assembly and the sealing sleeve using a vacuum pump, and allowing the vacuum-vacuumed sandwich glass assembly and the sealing sleeve to stand under the first environmental condition; under a second environmental condition, vacuuming the sandwich glass assembly and the sealing sleeve after standing under the first environmental condition using a vacuum pump, and removing the sealing sleeve after vacuuming; and after removing the sealing sleeve, allowing the sandwich glass assembly to stand under the second environmental condition to obtain an adhered vehicle window assembly.

[0046] For example, the window assembly can meet the following conditions: 1.1) The first glass body (110) and the second glass body (120) are transparent white glass; 1.2) The light transmittance of the first glass body (110) and the second glass body (120) in the visible light band is greater than 85% and less than or equal to 93%; 1.3) The light transmittance of the first intermediate layer (140) and the second intermediate layer (150) in the visible light band is greater than or equal to 85%; 1.4) The light transmittance of the dimming element (130) in the visible light band can be adjusted within an adjustable range, wherein the first light transmittance is the maximum value of the adjustable range and the second light transmittance is the minimum value of the adjustable range; wherein, within a first temperature range, the first light transmittance of the dimming element (130) is greater than or equal to 12%, and the second light transmittance of the dimming element (130) is less than or equal to 0.6%.

[0047] In some possible implementations, a third intermediate layer (160) is placed in the outer region of the first region before the sealing sleeve is installed.

[0048] Fourthly, an apparatus is provided that may include modules or units for implementing the methods of the second aspect and any possible implementation thereof.

[0049] For example, the device may include an acquisition unit and a processing unit. The acquisition unit is used to acquire dimming indication information; the processing unit is used to control the light transmittance of the window assembly in the visible light band according to the dimming indication information.

[0050] The window assembly can be the window assembly described in the first aspect above and any possible implementation thereof, or it can be any other window assembly with dimming function.

[0051] In some possible implementations, the dimming indication information can be used to indicate the rotation direction of the dimming knob and the duration of rotation in that direction. The processing unit can then be used to adjust the light transmittance of the window assembly in the visible light band based on the rotation direction and the duration.

[0052] In some possible implementations, the processing unit can be used to: adjust the transmittance of the dimming element in the visible light band to a first transmittance when the rotation direction is a first direction and the duration is greater than or equal to a first threshold; or, adjust the transmittance of the dimming element in the window assembly in the visible light band to a second transmittance when the rotation direction is a second direction and the duration is greater than or equal to a second threshold.

[0053] In some possible implementations, the dimming instruction information may include first manipulation information, which can be used to instruct the transmittance of the dimming element to be adjusted to a first transmittance or a second transmittance. The processing unit can be configured to: adjust the transmittance of the dimming element in the visible light band to the first transmittance or the second transmittance according to the first manipulation information.

[0054] In some possible implementations, the dimming indication information can be used to indicate the ambient temperature of the window assembly. The processing unit can be used to: adjust the transmittance of the window assembly in the visible light band according to the ambient temperature; and / or, determine adjustment parameters for the transmittance of the window assembly in the visible light band according to the ambient temperature.

[0055] In some possible implementations, the processing unit can be used to: use a first value as the ratio of a first transmittance to a second transmittance when the ambient temperature is within a first temperature range; or, use a second value as the ratio of a first transmittance to a second transmittance when the ambient temperature is within a second temperature range.

[0056] In some possible implementations, the processing unit can be used to: set a first transmittance to a range greater than or equal to 13% and less than 15% when the ambient temperature is within a first temperature range, and set a second transmittance to a range greater than 0.25% and less than or equal to 0.45%; set a first transmittance to a range greater than or equal to 9% and less than 11% when the ambient temperature is within a second temperature range, and set a second transmittance to a range greater than 0.4% and less than or equal to 0.6%; or set a first transmittance to a range greater than or equal to 6% and less than 8% when the ambient temperature is within a third temperature range, and set a second transmittance to a range greater than 0.25% and less than or equal to 0.45%.

[0057] In some possible implementations, the first temperature range may include a temperature range from -10 degrees Celsius to 50 degrees Celsius; the second temperature range may include a temperature range from 50 degrees Celsius to 65 degrees Celsius; and the third temperature range may include a temperature range from -20 degrees Celsius to -10 degrees Celsius.

[0058] In some possible implementations, the window assembly is in a first light transmittance position.

Specifically, at the first ambient temperature, the first light transmittance position can correspond to the third transmittance; at the second ambient temperature, the first light transmittance position can correspond to the fourth transmittance.

[0059] In some possible implementations, the dimming indication information may include cabin mode information. The processing unit may be used to: adjust the light transmittance of the window assembly (100) in the visible light band according to the cabin mode information, or to limit the adjustment of the light transmittance of the window assembly.

[0077] Figure 11 is a block diagram of another device provided in an embodiment of this application. Detailed Implementation

[0078] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0079] For example, FIG1 is a schematic diagram of a vehicle provided in an embodiment of the present application. As shown in FIG1, the window assembly in the vehicle 10 may include a front window assembly 11, a rear window assembly 12 and a rear quarter window assembly 13.

[0080] When vehicle 10 leaves the factory, the front window assembly 11, rear window assembly 12, and triangular window assembly 13 may all be transparent with high light transmittance. When using vehicle 10, the user may apply film to the inside of the window assemblies to improve cabin privacy, etc. If this is done, the windows will have low light transmittance regardless of the vehicle's usage scenario. However, in some usage scenarios, the user may expect higher light transmittance (e.g., when the user wants to view the scenery outside the vehicle); in this case, this method will not meet the user's needs.

[0081] Although people have developed dimming films that can adjust light transmittance (for example, they can be applied to glass assemblies such as sunroof assemblies), it is often difficult to meet the usage needs of different scenarios when setting dimming films in car windows.

[0082] On the one hand, for sunroof assemblies, the primary purpose of dimming is to avoid direct sunlight, so there's no need for the dimming film to achieve extremely low light transmittance. On the other hand, for window glass, the goal of dimming is to provide privacy for the cabin in dark conditions and to avoid obstructing the user's view in bright conditions. This difference in intended use leads to different requirements for dimming performance. In bright conditions, the dimming film / glass assembly with dimming functionality (such as sunroof assemblies or window assemblies with dimming capabilities) operates at a higher light transmittance within its adjustable range; conversely, in dark conditions, it operates at a lower light transmittance within the same range.

[0083] On the other hand, although the light transmittance of dimming films can vary within an adjustable range, due to limitations in film performance and cost considerations, the ratio between the maximum and minimum values ​​within this adjustable range (referred to as dimming contrast ratio) is often relatively small (e.g., this ratio can be less than 20), making it difficult to achieve a large dimming contrast ratio (e.g., 60, 100, etc.). Within the adjustable range, if the dimming film cannot achieve extremely low light transmittance, it cannot meet the need for privacy protection (e.g., even when the dimming film is in a dark state, one can still observe the lit mobile phone screen inside the cabin through the car window from outside the vehicle, and observe the user inside the cabin, etc.); if the dimming film can achieve extremely low light transmittance, due to the limitation of dimming contrast ratio, it will not be able to achieve high light transmittance in a bright state, which will interfere with the user's vision, and even cause the user in the cabin to feel confined and oppressed due to insufficient ambient light.

[0084] In view of this, this application provides a window assembly that can meet the needs of different usage scenarios by coordinating the light transmittance of each part of the window assembly.

[0085] For example, Figure 2 is a structural schematic diagram of a window assembly 100 provided in an embodiment of this application. The window assembly 100 may correspond to a front window assembly 11, a rear window assembly 12, or a triangular window assembly 13.

[0086] As shown in Figure 2, the window assembly 100 may include a glass body 110, a glass body 120, a dimming element 130, and an intermediate layer.

[0087] The dimming element 130 can be disposed in the first region of the window assembly; in the thickness direction of the window assembly 100, the dimming element 130 can be disposed between the glass bodies 110 and 120. The dimming element 130 can be bonded to the glass body 110 through the intermediate layer 140, and can be bonded to the glass body 120 through the intermediate layer 150.

[0088] For example, the dimming element 130 can achieve dimming using electrochromic, liquid crystal (LC), or other methods. For instance, the dimming element 130 can be an EC film. Another example is that the dimming element 130 can be a polymer dispersed liquid crystal (PDLC) film. Yet another example is that the dimming element 130 can be a dye liquid crystal (DLC) film.

[0089] Because the window assembly 100 uses a sandwich structure in the first area, the appearance of the window assembly 100 in bright and dark states is not only limited by the light transmittance of the dimming element, but also affected by various factors such as the light transmittance and color of the glass and the intermediate layer. Moreover, due to the limitations of the dimming contrast of the dimming film, if the adjustable range of the light transmittance of the dimming film is not set reasonably, the window assembly 100 will be unable to meet the usage needs in both bright and dark states.

[0090] Let a denote the transmittance of the glass body 110 in the visible light band as a; let b denote the transmittance of the glass body 120 in the visible light band as b; let c denote the transmittance of the intermediate layer 140 in the visible light band as c; let d denote the transmittance of the intermediate layer 140 in the visible light band as d; let M denote the adjustable range of the transmittance of the dimming element 130 in the visible light band as dimming interval M, let e denote the maximum value of dimming interval M, and let f denote the minimum value of dimming interval M.

[0091] To meet the usage requirements of the window assembly 100 in different scenarios, the window assembly 100 can meet the following conditions: 1.1) Glass bodies 110 and 120 are made of transparent glass; 1.2) The light transmittance a of glass body 110 is greater than 83% and less than or equal to 93%; 1.3) The light transmittance of glass body 120 is greater than 83% and less than or equal to 93%; 1.4) Light transmittance c and d are greater than or equal to 85%; 1.5) For dimming range M, light transmittance e is greater than or equal to 12%, and light transmittance f is less than or equal to 0.6%.

[0092] In some possible implementations, the dimming element 130 may have different adjustable ranges in different temperature ranges. Condition 1.5 above can refer to the following: within the global operating temperature range, or within a partial operating temperature range (such as the main operating temperature range, secondary operating temperature range, etc.), the transmittance e can be greater than or equal to 12%, and the transmittance f can be less than or equal to 0.6%.

[0093] The primary, secondary, and global operating temperature ranges of the window assembly 100 may vary depending on the vehicle's intended sales region (e.g., Europe, America, Asia). Let's assume this primary and global operating temperature range is a first temperature range. For example, this first temperature range could be a temperature range from 15 degrees Celsius (°C) to 45°C. Alternatively, it could be a temperature range from -10°C to 50°C. Furthermore, within this first temperature range, for the dimming range M, the light transmittance e could be 12.5%, 14%, or 13%; and f could be 0.35%, 0.5%, or 0.6%. For example, the first temperature range and / or the adjustable range of light transmittance can be set according to actual usage requirements; and for example, the glass bodies 110 and 120 can be transparent clear glass.

[0094] For example, the adjustable range of the dimming element 130 can vary within different temperature ranges; that is, the maximum and / or minimum values ​​of the dimming interval M can correspond to the ambient temperature of the dimming film. For instance, the transmittance e can be 14% in the temperature range of 10°C to 50°C, while in the temperature range of 50°C to 65°C, the transmittance e can be set to 10%.

[0095] In real-world scenarios, if glass elements 110 and / or 120 are made of other types of glass, such as frosted glass, in bright conditions, when a user observes objects outside the vehicle through the window assembly 100 from inside the cabin, the frosted glass will act as a "filter," affecting the user's ability to see objects outside. If the light transmittance of glass elements 110 and / or 120 is less than 83%, to meet the usage requirements in bright conditions, the maximum light transmittance e of the dimming range M needs to be set to a higher value; however, due to the limitation of dimming contrast, the minimum light transmittance f will need to be increased accordingly, making it difficult for the window assembly to meet the privacy protection requirements in dark conditions. If the light transmittance of glass elements 110 and / or 120 exceeds 93%, to meet the usage requirements in dark conditions, the minimum light transmittance f of the dimming element 130 needs to be set to a smaller value; however, due to the limitation of dimming contrast, the maximum light transmittance e will need to be reduced accordingly, making it difficult for the window assembly to meet the usage requirements in bright conditions.

[0096] In this embodiment, by coordinating the performance of each layer in the window assembly, the dimming performance of the dimming element can be effectively balanced to meet the usage needs of the window assembly in different scenarios.

[0097] In actual mass production, the performance of the same type of components from different batches and production dates will inevitably differ. Inappropriate control methods will lead to serious fluctuations in the light transmission performance of the same type of car window assemblies.

[0098] In some possible implementations, in the case of mass production, in order to ensure that the same type of window assembly has consistent light transmission performance, the window assembly 100 can meet the following conditions: 2.1) Light transmittance a can be greater than 88% and less than or equal to 92%; 2.2) Light transmittance b can be greater than 88% and less than or equal to 92%; 2.3) Light transmittance c and d can be greater than or equal to 88%; 2.4) Light transmittance e can be greater than or equal to 14% and less than 17%; 2.5) Light transmittance f can be greater than 0.3% and less than or equal to 0.5%.

[0099] For example, in mass production, the design value of transmittance 'a' can be set to 90.3%, and a fluctuation of ±1% in transmittance 'a' is allowed based on the design value; in this way, transmittance 'a' can meet the above condition 2.1). The control methods for other parameters (such as transmittance b, c, d, etc.) are similar and will not be elaborated here.

[0100] In this embodiment of the application, by further controlling the performance of each component, it is possible to ensure that the window assembly has consistent light transmission performance in the case of mass production.

[0101] In addition, when setting up dimming functions for the window assembly, besides considering whether the dimming performance can meet the needs of different usage scenarios, it may also be necessary to consider the impact of dimming elements and related structures on the appearance of the window / vehicle. For example, dimming elements such as EC film and PDLC film often have electrodes. In order to prevent the electrodes and other related structures from being exposed in the user's field of vision, a shielding layer can be set on the glass to cover these structures.

[0102] In some possible implementations, the window assembly 100 may further include a shielding layer disposed on a first surface of the glass body. The end of the shielding layer away from the first region may correspond to the end of the peripheral region, and the end of the shielding layer near the first region may correspond to the end of the dimming element. For example, a shielding layer 171 may be disposed on the surface of the glass body 110, and a shielding layer 172 may be disposed on the surface of the glass body 120. In this case, the surface of the glass bodies 110 and 120 near the dimming element may correspond to the first surface. As another example, assuming the glass body 120 is disposed near the cabin side, a shielding layer 173 may be disposed on the surface of the glass body 120 near the cabin side, eliminating the need for a shielding layer 172. In this case, the surface of the glass body 120 away from the dimming element may correspond to the first surface. The aforementioned shielding layers 171, 172, and 173 can be used to shield the gap between the dimming element 130 and the intermediate layer 160, the electrodes of the dimming element 130, and other structures; they can also be used to shield the tape assembly when the dimming element 130 is provided with it. For example, the end of the shielding layer furthest from the first region can be at the same position as the end of the peripheral region, or it can maintain a certain gap (e.g., 3 or 5 millimeters) with the end of the peripheral region. Similarly, the end of the shielding layer closest to the first region can be at the same position as the end of the dimming element, or it can maintain a certain gap between them.

[0103] In this embodiment of the application, a masking layer is provided to achieve an aesthetic effect.

[0104] While sunroof assemblies and other glass assemblies with dimming functions may also have corresponding shielding layers, windows are more readily visible to the user than other glass assemblies, making them more noticeable. When dimming elements like films are placed on other glass assemblies, the impact of the shielding layer on the vehicle's aesthetics can be less of a concern; however, when placed on windows, the deterioration of the vehicle's appearance due to the shielding layer cannot be ignored. From the user's perspective, improperly placed dimming films will severely degrade the vehicle's aesthetics.

[0105] On the other hand, due to the different locations of the window assembly and sunroof assembly within the vehicle, their physical and chemical environments also differ. Sunroof assemblies often have a convex shape, higher in the center and lower on both sides, and vehicles typically have corresponding sealing structures / devices on the sides of the sunroof glass. However, for window assemblies, the sides may be exposed to rain, dust, and other environmental factors. For dimming elements such as EC mirrors, whose performance is easily affected by water, oxygen, and other substances, an inappropriate structural design of the window assembly will not only affect its aesthetics but also its durability.

[0106] In some possible implementations, the window assembly 100 may also include an intermediate layer 160. The intermediate layer 160 may be disposed in the outer region of the first region; the intermediate layer 160 may be used to bond the glass bodies 110 and 120, and the intermediate layer 160 and the glass bodies 110 and 120 may also form a receiving space, which may be used to receive the sandwich structure formed by the dimming element 130, the intermediate layer 140 and the intermediate layer 150.

[0107] For example, as shown in Figure 2, the intermediate layer 160 can form a frame structure, and the dimming element 130 and intermediate layers 140 and 150 can be disposed inside the frame structure. That is, for the window assembly 100, in the first region, the window assembly 100 can include a five-layer sandwich structure composed of glass body 110, intermediate layer 140, dimming element 130, intermediate layer 150 and glass body 120; while in the outer region of the first region, the window assembly 100 can include a three-layer sandwich structure composed of glass body 110, intermediate layer 160 and glass body 120.

[0108] In some embodiments, the width of the intermediate layer 160 may be less than or equal to 15 mm or 18 mm.

[0109] Assuming that a five-layer sandwich structure is also used in the outer area (for example, extending the intermediate layers 140 and 150 to the edge of the window assembly 100, and setting another intermediate layer with the dimming element 130 in the outer area to bond the aforementioned intermediate layers 140 and 150); when substances such as water, oxygen, and dust invade the window assembly, there will be 4 places where the intrusive interlayer structure (i.e., the adhesive gap between every two layers) can be penetrated.

[0110] During the use of a car window assembly, there are inevitably interaction forces between the layers. With long-term use, these interaction forces will deteriorate the adhesive gaps, making it easier for substances such as water, oxygen, and dust to penetrate into the interior of the car window assembly.

[0111] If a five-layer sandwich structure is also used in the outer area, to meet the durability requirements of the window assembly, the width of the outer area (or the width of the middle layer parallel to the dimming element) needs to be sufficiently large (e.g., 50 mm or more) to ensure a strong enough adhesive seam at the edge, preventing water, oxygen, and other substances from penetrating the area where the dimming element 130 is located. This width is particularly important for dimming elements such as the EC film, whose performance is easily affected by water and oxygen. However, this would result in an excessively wide shielding layer, severely impacting the vehicle's appearance.

[0112] For the window assembly 100, on the one hand, in the outer area, the glass bodies 110 and 120 are bonded together by the intermediate layer 160; when substances such as water, oxygen, and dust invade the window assembly 100, the number of intrusive interlayer structures can be reduced to two. On the other hand, when substances such as water, oxygen, and dust invade the outer area and further invade the area where the dimming element 130 is located, the portion of these substances that have already invaded the outer area needs to be further distributed to multiple interlayer structures in the first area, and their invasion direction needs to be changed before they can invade the area where the dimming element 130 is located, thus further reducing the number of substances that can invade the area where the dimming element 130 is located.

[0113] In this embodiment, the cooperation between multiple intermediate layers reduces the amount of water, oxygen, dust, and other substances that can intrude into the area where the dimming element 130 is located. Using a narrower intermediate layer 160 avoids the influence of water, oxygen, and other substances on the dimming element. This method helps reduce the width of the shielding layer, minimizing the deterioration of the vehicle's appearance caused by the dimming element, thus balancing practicality and aesthetics.

[0114] For example, the first region may be located at the center of the window assembly 100. For instance, if the window assembly 100 corresponds to the triangular window assembly 13, the first region may be located at the center of the triangular window.

[0115] In some possible implementations, the first region may also be located near the edge region of one side of the window assembly 100. The following example, with reference to Figure 3, illustrates the first region and the edge region of the first region, using the window assembly 100 corresponding to the rear window assembly 12 as an example.

[0116] For example, Figure 3 is a schematic diagram of the area division of the window assembly provided in an embodiment of this application.

[0117] In one embodiment, for the retractable front / rear door window assembly, the upper half is exposed beyond the door sheet metal, while the lower half is obscured by the door sheet metal. As shown in Figure 3(a), region A can be offset from the center of the window and positioned near the edge of the upper half of the window assembly; other regions outside region A can constitute region B. A dimming element can be positioned in region A, and the intermediate layer 160 can cover region B. In this case, region A can correspond to the aforementioned first region, and region B can correspond to the outer perimeter of the first region.

[0118] In another embodiment, to reduce the weight and cost of the window assembly, region B can be further divided into region C and region D; region D can be understood as the lower half of region B that is not within the user's field of vision. An intermediate layer 160 can be disposed in region C, and the upper halves of the two glass bodies 110 and 120 are bonded together via the intermediate layer 160. To improve the reliability of the window assembly, an intermediate layer E can be disposed in region D to bond the lower halves of the two glass bodies. In this case, region A can correspond to the first region, and region C can correspond to the outer region of the first region.

[0119] The first area of ​​the window assembly 100 and the outer area of ​​the first area can also refer to the corresponding areas of the glass body 110 and 120.

[0120] In some possible implementations, the dimming element 130 may include a main body portion 131 and a tape assembly 132. The top of the tape assembly 132 may be attached to the upper surface 1311 of the main body portion 131, and the bottom of the tape assembly 132 may be attached to the lower surface 1312 of the main body portion 131.

[0121] Assume that the main body 131 adopts a multilayer membrane structure; in this case, its upper surface 1311 and lower surface 1312 may belong to different membranes. The following is an illustrative example with reference to Figure 4. Figure 4 adopts the same or similar perspective as Figure 2(b).

[0122] For example, FIG4 is a schematic diagram of the structure of the dimming element 130 provided in an embodiment of the present application.

[0123] In one embodiment, the tape assembly 132 may be a single tape; the tape assembly 132 may be C-shaped in cross-section. For example, as shown in FIG4(a), the top of the tape is attached to the upper surface 1311 of the body portion 131, the bottom of the tape is attached to the lower surface 1312 of the body portion 131, and the middle portion of the tape may be attached to the side of the body portion 131.

[0124] In another embodiment, the tape assembly 132 may include a plurality of tapes; adjacent tapes may be bonded to each other. For example, as shown in FIG3(b), the tape assembly 132 may include tape 1321 and tape 1322; the top of tape 1321 is attached to the upper surface 1311 of the body portion 131, and its bottom is attached to the top of tape 1322; the bottom of tape 1322 is attached to the lower surface 1312 of the body portion 131.

[0125] In this embodiment, by providing an adhesive tape assembly, it is possible to further prevent substances such as water, oxygen, and dust from entering the dimming element 130 from the side, thereby further improving the water resistance and oxygen resistance of the window assembly.

[0126] For example, the window assembly 100 may also include a wiring harness assembly 135, which may be connected to the electrodes of the dimming element.

[0127] For the window assembly, the surfaces of glass bodies 110 and 120 are often curved, and the gap between glass bodies 110 and 120 is small. When a conventional wiring harness is used to connect to the electrodes of the dimming element 130, a portion of the wiring harness will inevitably be located between the two glass bodies. On the one hand, improper diameter setting may cause damage to the glass bodies; on the other hand, it is prone to shaking due to vehicle vibration, thereby generating noise problems.

[0128] In some possible implementations, the wiring harness assembly 135 may include a flexible circuit board (FPC); the FPC may be connected to the electrodes of the dimming element 130; one end of the FPC near the dimming element 130 may be disposed between the glass bodies 110 and 120.

[0129] Because flexible circuit boards are thin and easily deformable, in this embodiment, by using a flexible circuit board connected to the electrodes of the dimming element 130, damage to the glass body by the wiring harness assembly can be avoided.

[0130] For example, the window assembly 100 may also include a wiring harness fixing assembly 180. For instance, the wiring harness fixing assembly 180 may be disposed on the inner surface of the window assembly 100. For the front door glass and the rear door glass, which may be repeatedly raised and lowered during use, disposing of the wiring harness fixing assembly 180 on the inner surface of the window assembly 100 (i.e., the surface of the window assembly 100 facing the passenger compartment) and fixing the wiring harness assembly 135 to the wiring harness fixing assembly 180 helps to extend the service life of the wiring harness assembly.

[0131] For example, FIG5 is a schematic diagram of an arrangement of a wire harness assembly provided in an embodiment of the present application.

[0132] As shown in Figure 5, the wiring harness fixing assembly 180 can be bonded to the inner surface of the vehicle window glass; the wiring harness assembly 135 may include a flexible circuit board 1351 and a wiring harness 1352. A portion 1353 of the flexible circuit board 1351 can be disposed between the glass bodies 110 and 120 and connected to the electrodes of the dimming element 130; another portion 1354 of the flexible circuit board 1351 can be disposed on the wiring harness fixing assembly 180 by means of bonding, snap-fitting, etc. The wiring harness 1352 can be used to connect to the vehicle wiring harness.

[0133] In some possible implementations, the intermediate layer in the window assembly 100, such as intermediate layers 140, 150, 160, etc., can be made of materials suitable for laminated glass, such as polyvinyl butyral (PVB) and SGP film.

[0134] In some possible implementations, the dimming element 130 may include an EC film.

[0135] In real-world scenarios, while PDLC, DLC, and spectral power distribution (SPD) films can achieve dimming, compared to EC films, PDLC films exhibit higher haze in both bright and dark states, resembling frosted glass. Even in bright states, this can create a sense of confinement and oppression for users in the cabin. DLC films display a certain color in bright and intermediate states, acting as a "filter" and causing color distortion in the observed objects. SPD films, on the one hand, appear blue in both bright and dark states, and on the other hand, their high operating voltage (e.g., 110 volts or 120 volts) poses a safety hazard.

[0136] In this embodiment, an EC film is used as a dimming element. On the one hand, its dimming rate can achieve a wide adjustable range; on the other hand, its bright state, dark state and intermediate state are all neutral colors, which will not cause the scene observed by the user to have color deviation from the actual scene, nor will it bring the user an additional sense of oppression and restraint.

[0137] The window assembly provided in the embodiments of this application has been described above with reference to Figures 1 to 5. The embodiments of this application also provide a control method, which will be described below with reference to Figures 6 to 8.

[0138] For example, FIG6 is a schematic flowchart of a control method provided in an embodiment of the present application.

[0139] The method 600 can be executed by a control device of a window assembly with dimming function, or by a component of the control device (such as a chip, processor, processing circuit, etc.), or by a system or vehicle containing the control device. For example, the window assembly with dimming function can be window assembly 100, or it can be other window assemblies with dimming function. The method 600 may include:

[0140] S610, obtain dimming instruction information.

[0141] In some embodiments, the control device for the window assembly may include a dimming knob and / or dimming buttons. Dimming indication information may include information about the operation of the dimming knob and / or buttons. For example, rotating the dimming knob clockwise may indicate an increase in the light transmittance of the window assembly; rotating the dimming knob counterclockwise may indicate a decrease in the light transmittance of the window assembly.

[0142] In other embodiments, the dimming indication information may include ambient temperature information. For example, to ensure the performance and lifespan of the dimming element, different dimming performance settings can be applied to the dimming element in different temperature ranges. The light transmittance of the window assembly can be adjusted by regulating the light transmittance of the dimming element in the visible light band based on the ambient temperature information.

[0143] In some embodiments, the dimming indication information may include cabin mode information. For example, the cabin may have multiple usage modes, such as movie mode, rest mode, and normal mode. In movie mode, it may be desirable for the window assembly to be at its lowest adjustable transmittance to avoid external light affecting the viewing experience; in rest mode, it may be desirable for the window assembly to be at a lower transmittance to provide a dim environment that promotes sleep; in normal mode, it may be desirable for the window assembly to be at a higher transmittance to provide a clear view of the outside; and in child mode, it may not be desirable for the user to adjust the transmittance of the window assembly using dimming knobs or similar devices. The transmittance of the window assembly can be controlled based on the cabin mode.

[0144] The S620 controls the light transmittance of the window assembly in the visible light band based on dimming instructions.

[0145] For example, controlling the light transmittance of a vehicle window assembly in the visible light band may include: adjusting the light transmittance of the vehicle window assembly in the visible light band; and / or determining adjustment parameters for the light transmittance of the vehicle window assembly in the visible light band. For instance, the light transmittance of the vehicle window assembly in the visible light band can be adjusted based on the rotation direction of the dimming knob and the operation information of the dimming button. Another example is that multiple light transmittance levels can be defined, and the light transmittance level of the vehicle window assembly can be increased or decreased accordingly based on the user's operation of the dimming knob and dimming button, thereby achieving adjustment of the light transmittance. Yet another example is that the adjustable range of the light-transmitting element can be adjusted.

[0146] For example, controlling the light transmittance of the window assembly in the visible light band may also include limiting the adjustment of the light transmittance of the window assembly in the visible light band. For instance, when the cabin is in child mode, the adjustment of the light transmittance of the window assembly may be limited.

[0147] In some possible implementations, the dimming indication information can indicate the direction of rotation of the dimming knob and the duration of rotation of the dimming knob in that direction. Controlling the light transmittance of the window assembly in the visible light band based on the dimming indication information can include: adjusting the light transmittance of the window assembly in the visible light band according to the direction and duration of rotation of the dimming knob.

[0148] For example, when the dimming knob is rotated in a first direction and the duration of rotation in that direction is less than a first threshold (e.g., 1.5 seconds, 2 seconds), the light transmittance of the window assembly in the visible light band can be increased based on the rotation amplitude of the dimming knob. As another example, when the dimming knob is rotated in a second direction and the duration of rotation in that direction is less than a second threshold (e.g., 1.5 seconds, 2 seconds, 2.5 seconds), the light transmittance of the window assembly in the visible light band can be decreased based on the rotation amplitude of the dimming knob. The first direction can be either clockwise or counterclockwise, and the second direction can be either clockwise or counterclockwise. The first threshold and the second threshold can be the same or different.

[0149] For example, when the dimming knob is rotated in a first direction and the duration of rotation in that direction is greater than or equal to a first threshold, the transmittance of the dimming element in the visible light band is adjusted to the maximum value of its adjustable range (i.e., adjusted to transmittance e). For example, when the dimming knob is rotated in a second direction and the duration of rotation in that direction is greater than or equal to a second threshold, the transmittance of the dimming element in the visible light band is adjusted to the minimum value of its adjustable range (i.e., adjusted to transmittance f).

[0150] In other words, when a user rotates the dimming knob, if the operation of the dimming knob is completed within a short time (less than the corresponding threshold), the light transmittance of the car window glass can be adjusted based on the direction and amplitude of the rotation of the knob; while if the dimming knob is continuously rotated in a certain direction for a longer period of time, the light transmittance of the car window glass can be adjusted to the maximum value of the light transmittance corresponding to that direction.

[0151] In this embodiment, the light transmittance of the window assembly is directly adjusted to the maximum or minimum value based on the rotation direction of the dimming knob and the duration of rotation in that direction, which simplifies the user's adjustment process for the light transmittance.

[0152] In some possible implementations, when the number of intermittent rotations of the dimming knob in the first time period (e.g., 5 or 6 seconds) is greater than or equal to a certain threshold (e.g., 8 or 10 times), the adjustment of the light transmittance of the window assembly is paused, and after the second time period (e.g., 5 or 10 seconds), the light transmittance of the window assembly is adjusted according to the direction of the last intermittent rotation of the dimming knob in the first time period.

[0153] For example, if it is detected that the user intermittently rotates the dimming knob 10 times within 5 seconds, the adjustment of the light transmittance of the window assembly is paused, and after 20 seconds, the light transmittance of the window assembly is adjusted according to the direction of the last rotation during this period.

[0154] Since the lifespan of a dimming element is often related to the number of dimming cycles, in this embodiment of the application, by delaying the adjustment of the light transmittance of the window assembly, damage to the lifespan of the dimming element due to user misoperation can be avoided.

[0155] In some possible implementations, the dimming instruction information may include first control information, which can be used to instruct the dimming element to adjust its transmittance in the visible light band to a first transmittance or a second transmittance. The transmittance of the vehicle window glass in the visible light band can be adjusted according to the first control information.

[0156] For example, the control device for the window assembly may be equipped with button A and / or button B; triggering button A indicates that the light transmittance is to be adjusted to the maximum value of the adjustable range; triggering button B indicates that the light transmittance is to be adjusted to the minimum value of the adjustable range. Depending on the triggering of button A and button B, the light transmittance of the window glass in the visible light band can be adjusted accordingly to the maximum or minimum value of the adjustable range.

[0157] For example, the dimming knob can be pressed; when the current transmittance is greater than the middle value of the adjustable range, pressing the dimming knob indicates that the transmittance is expected to be adjusted to the maximum value of the adjustable range; when the current transmittance is less than the middle value of the adjustable range, pressing the dimming knob indicates that the transmittance is expected to be adjusted to the minimum value of the adjustable range.

[0158] In this embodiment of the application, the transmittance is adjusted to the maximum or minimum value with one click according to the first operation information, which helps to simplify the user's process of adjusting the transmittance.

[0159] In some possible implementations, the dimming indication information can be used to indicate the ambient temperature of the window assembly. Controlling the light transmittance of the window assembly in the visible light band based on the dimming indication information may include: adjusting the light transmittance of the window assembly in the visible light band according to the ambient temperature; and / or, determining adjustment parameters for the light transmittance of the window assembly in the visible light band according to the ambient temperature.

[0160] For example, different dimming ranges can be set for the dimming element within different temperature ranges to prevent damage due to a mismatch between the dimming performance and the operating temperature. For instance, at an ambient temperature of 20°C, the transmittance of the dimming element is the maximum value of 13% within the adjustable range corresponding to that temperature; when the ambient temperature changes to -10°C, the maximum value of the adjustable range changes by 9%. If the transmittance of the dimming element is still kept at 13%, the dimming element may be damaged due to prolonged exposure to inappropriate transmittance. After the ambient temperature changes, the transmittance can be adjusted accordingly to ensure that the transmittance of the dimming element remains within the corresponding adjustable range, thus guaranteeing the lifespan of the dimming element.

[0161] In this embodiment, adjusting the light transmittance and / or the light transmittance adjustment parameters of the window assembly according to the ambient temperature helps to ensure the dimming performance and service life of the window assembly.

[0162] Among some possible implementations, determining the adjustment parameters of the window assembly in the visible light band based on the ambient temperature may include: when the ambient temperature is within a first temperature range, using a first value as the ratio of a first light transmittance to a second light transmittance; or, within a second temperature range, using a second value as the ratio of a first light transmittance to a second light transmittance.

[0163] For example, different dimming performance can be set for the dimming element in different temperature ranges to prevent damage to the dimming element due to mismatch between the dimming performance and the operating temperature. For example, taking the dimming element 130 as an example, in the temperature range of 15℃ to 45℃, the ratio of transmittance e to f can be 35 to 40 times; in the temperature range of -20℃ to -10℃, the ratio of transmittance e to f can be 15 to 20 times; and in the range of 50℃ to 65℃, the ratio of transmittance e to f can be 20 to 25 times. In this example, the temperature range of 15℃ to 45℃ can correspond to the first temperature range, and the temperature ranges of -20℃ to -10℃ and 50℃ to 65℃ can correspond to the second temperature range.

[0164] In this embodiment, different ratios are set for the first transmittance and the second transmittance in different temperature ranges, which helps to ensure the service life of the dimming element while meeting usage requirements.

[0165] In some possible implementations, determining the adjustment parameters of the window assembly in the visible light band based on the ambient temperature may include: setting a first light transmittance to a range greater than or equal to 13% and less than 15% when the ambient temperature is within a first temperature range, and setting a second light transmittance to a range greater than 0.25% and less than or equal to 0.45%; setting a first light transmittance to a range greater than or equal to 9% and less than 11% when the ambient temperature is within a second temperature range, and setting a second light transmittance to a range greater than 0.4% and less than or equal to 0.6%; or setting a first light transmittance to a range greater than or equal to 6% and less than 8% when the ambient temperature is within a third temperature range, and setting a second light transmittance to a range greater than 0.25% and less than or equal to 0.45%.

[0166] In some possible implementations, the first temperature range may include a temperature range from -10 degrees Celsius to 50 degrees Celsius; the second temperature range may include a temperature range from 50 degrees Celsius to 65 degrees Celsius; and the third temperature range may include a temperature range from -20 degrees Celsius to -10 degrees Celsius.

[0167] In this embodiment, different values ​​are set for the first transmittance and the second transmittance in different temperature ranges, which helps to ensure the service life of the dimming element while meeting the usage requirements.

[0168] In some possible implementations, the window assembly is in a first light-transmitting position. Adjusting the light transmittance of the window assembly in the visible light band according to the ambient temperature can include: when the ambient temperature changes from a first ambient temperature to a second ambient temperature, adjusting the light transmittance of the window assembly in the visible light band from a third light transmittance to a fourth light transmittance. Specifically, at the first ambient temperature, the first light transmittance position can correspond to the third light transmittance; at the second ambient temperature, the first light transmittance position can correspond to the fourth light transmittance. For example, the first light transmittance position can be any position; the third light transmittance can be any value; and the fourth light transmittance can be any value different from the third light transmittance.

[0169] In this embodiment, by adjusting the light transmittance, the window assembly can be maintained at the first light transmittance level even if the ambient temperature changes; this avoids the light transmittance level changing with the ambient temperature and achieves the effect of maintaining the light transmittance level.

[0170] The following example, in conjunction with Table 1, illustrates the correspondence between the adjustable range and the temperature range.

[0171] Table 1

[0172] For example, in extremely harsh ambient temperatures, controlling the light transmittance of the dimming element within its adjustable range may reduce its lifespan. Therefore, as shown in Table 1, dimming of the dimming element can be restricted when the ambient temperature is below -20°C to achieve low-temperature protection for the dimming element / window assembly; similarly, dimming of the dimming element can be restricted when the ambient temperature is above 65°C to achieve high-temperature protection for the dimming element / window assembly.

[0173] For example, as shown in Table 1, within the temperature range of -10℃ to 50℃, the adjustable range of the transmittance of the dimming element in the visible light band can be 0.4% to 13%. Within the temperature ranges of -20℃ to -10℃ and 50℃ to 65℃, the adjustable range can be appropriately reduced due to the influence of ambient temperature. In this example, the temperature range of -10℃ to 50℃ corresponds to the first temperature range; the temperature range of -20℃ to -10℃ corresponds to the second temperature range; and the temperature range of 50℃ to 65℃ corresponds to the third temperature range.

[0174] For example, at an ambient temperature of 40℃, the window assembly can be in a bright state, with a light transmittance of 13%, the maximum transmittance within that temperature range. When the ambient temperature changes to the secondary operating temperature range of 50℃ to 65℃, the light transmittance of the window assembly can be automatically adjusted to the maximum transmittance of 8% within that temperature range. When the ambient temperature further rises to the high-temperature protection range, the high-temperature protection function can be automatically activated. This method extends the lifespan of the dimming element / window assembly while meeting user needs.

[0175] For example, assuming the window assembly has light transmission levels from level 1 to level 5, the light transmittance corresponding to each level can be determined according to the adjustable range in Table 1. At an ambient temperature of 40℃, the window assembly is in level 1. When the ambient temperature changes to the secondary operating temperature range of 50℃ to 65℃, the change in ambient temperature causes a change in the adjustable range of light transmittance. If the light transmittance remains unchanged, the light transmission level may change. Therefore, the light transmittance can be adjusted according to the ambient temperature so that the window assembly's light transmission level remains at level 1. This method achieves the effect of level maintenance, preventing the light transmission level from changing due to variations in ambient temperature. In this example, level 1 corresponds to the first dimming level.

[0176] It is understandable that the correspondence between the adjustable range and the temperature range shown in Table 1 above is just an example.

[0177] In other embodiments, low-temperature protection, high-temperature protection, primary operating temperature range, and secondary operating temperature range can be defined in other ways. For example, low-temperature protection may be activated only when the ambient temperature is below -30°C, and high-temperature protection may be activated only when the ambient temperature is above 70°C.

[0178] In other embodiments, the adjustable range of the dimming element in each temperature range may differ from that in Table 1. For example, within the temperature range of -10°C to 50°C, the corresponding adjustable range may be 0.35% to 14%.

[0179] In this embodiment, different dimming parameters are used to control the dimming rate of the window assembly in different temperature ranges, which is beneficial to improving the service life of the dimming element and the window assembly.

[0180] The method 600 is illustrated below with reference to the controllers shown in Figures 7 and 8.

[0181] For example, FIG7 is a schematic diagram of the structure of a controller provided in an embodiment of this application.

[0182] As shown in Figure 7, the controller 700 may include a base 710, a knob 720, and a handle 730. By operating the knob, the user can adjust the drive current of the dimming element 130 in the window assembly 100, and control the window assembly to be in the desired light transmission state.

[0183] For example, rotating knob 720 clockwise can increase the transmittance of the window assembly in the visible light band. Conversely, rotating knob 720 counterclockwise can decrease the transmittance of the window assembly in the visible light band.

[0184] In some embodiments, when the duration of rotating the knob in a certain direction is greater than or equal to a certain threshold (e.g., 2 seconds, 1.5 seconds, etc.), the transmittance of the window assembly to visible light can be adjusted to the limit value of visible light transmittance corresponding to that direction.

[0185] Assume that rotating knob 720 clockwise increases the transmittance of the window assembly to visible light, and rotating it counterclockwise decreases the transmittance. For example, rotating knob 720 clockwise for more than 2 seconds adjusts the transmittance to the maximum value in the bright state. Rotating it counterclockwise for more than 2 seconds adjusts the transmittance to the minimum value in the dark state.

[0186] For example, the knob supports press adjustment. For instance, when the light transmittance of the window assembly for visible light is at its maximum within the adjustable range, pressing the button can directly adjust the light transmittance to its minimum within the adjustable range; and vice versa. In other words, pressing the button allows for one-click flipping of the light transmittance.

[0187] In other embodiments, when the ambient temperature is detected to be within the low-temperature protection / high-temperature protection range, the controller 700 can send an instruction to the vehicle controller to instruct the power supply to the dimming element to be disconnected. This method enables the low-temperature protection / high-temperature protection function.

[0188] In some embodiments, multiple light transmittance levels can be set based on the transmittance of the window assembly to visible light. The controller 700 may also include a light transmittance indicator component 740. For example, this indicator component may include multiple indicator lights, allowing the user to determine the current light transmittance based on the number of illuminated lights. For another example, assuming clockwise rotation increases light transmittance and counter-clockwise rotation decreases it, pressing and rotating the button clockwise increases the light transmittance, and conversely, pressing and rotating the button counter-clockwise decreases it. For yet another example, when the ambient temperature changes from one temperature range to another, the controller 700 can automatically adjust the light transmittance of the window assembly based on the ambient temperature to maintain the desired light transmittance.

[0189] For example, Figure 8 is a schematic diagram of another controller provided in an embodiment of this application.

[0190] As shown in Figure 8, the controller 800 may include a base 810, buttons 820 and 830. For example, pressing button 820 can reduce the transmittance of the window assembly to visible light; pressing button 830 can increase the transmittance of the window assembly to visible light.

[0191] The controller 800 may also be a gear position indicator component 840; the function of the gear position indicator component 840 may be similar to that of the gear position indicator component 740.

[0192] In some possible implementations, the controller 800 may also support gear holding functionality.

[0193] The control method provided in the embodiments of this application has been illustrated above with reference to Figures 6 to 8. The embodiments of this application also provide a method for manufacturing a window assembly, which is illustrated below with reference to Figure 9.

[0194] For example, Figure 9 is a schematic flowchart of a method for manufacturing a vehicle window assembly according to an embodiment of this application. The method 900 may include:

[0195] S910, intermediate layers 140 and 150 are respectively disposed on two opposite surfaces of the dimming element 130 to form a sandwich structure.

[0196] S920, glass bodies 110 and 120 are respectively disposed on two oppositely disposed surfaces of the sandwich structure, and the sandwich structure is disposed in the first region of glass bodies 110 and 120 to obtain a sandwich glass assembly.

[0197] S930 places the sealing sleeve around the laminated glass assembly.

[0198] A suitable rubber ring can be selected based on the size of the laminated glass assembly; after the rubber ring is put on the laminated glass assembly, there can be no gap between the rubber ring and the laminated glass assembly; thus, the rubber ring can provide a sealed environment for vacuum pumping.

[0199] S940, under the first environmental condition, the laminated glass assembly and sealing sleeve are vacuumed by a vacuum pumping device, and the laminated glass assembly and sealing sleeve after vacuuming are left to stand under the first environmental condition.

[0200] The first environmental condition can be a cold environment, such as room temperature.

[0201] Vacuum evacuation in a cold environment can remove most of the air between the layers.

[0202] S950, under the second environmental condition, the laminated glass assembly and sealing sleeve, which have been left to stand under the first environmental condition, are vacuumed using a vacuum pump, and the sealing sleeve is removed after the vacuum pumping is completed.

[0203] The second environmental condition can be a high temperature and high pressure environment, such as an ambient temperature of 130℃~150℃ and an ambient pressure of 10-13 atmospheres.

[0204] Under high temperature and high pressure, vacuum extraction can bond the edge of the interlayer to the glass body and / or dimming element, thus achieving initial bonding of the laminated glass assembly.

[0205] S960, after removing the sealing sleeve, allow the laminated glass assembly to stand under the second environmental conditions.

[0206] By allowing the material to stand under a second environmental condition, the intermediate layer can be tightly bonded to the glass body and / or the dimming element, and the air between the layers can be expelled.

[0207] In some embodiments, the intermediate layer 160 may be disposed in the peripheral region of the first region of the glass bodies 110 and 120 before the sealing sleeve is disposed.

[0208] In other embodiments, the wiring harness assembly 135 is connected to the electrodes of the dimming element 130 before the sealing sleeve is applied.
