Description

Technical Field

[0001] The present application relates to the technical field of smart vehicles, and more particularly, to a vehicle window assembly and a vehicle. Background Art

[0002] To enhance cabin privacy, users can apply window film. However, this method limits the light transmittance of the windows to a fixed value, which is not conducive to user use in certain scenarios. Utility Model Content

[0003] The present application provides a vehicle window assembly and a vehicle, which, by coordinating the light transmittance of each layer in the vehicle window assembly, can effectively take into account the use requirements of the vehicle window assembly in different scenarios when the dimming performance of the dimming element is limited.

[0004] 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 intermediate layer, and a second intermediate layer. 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 via the first intermediate layer and to the second glass body via the second intermediate layer.

[0005] The vehicle window assembly satisfies the following conditions: 1.1) the first glass body and the second glass body are transparent glass; 1.2) the transmittance of the first glass body and the second glass body in the visible light band is greater than 83% and less than 93%; 1.3) the transmittance of the first intermediate layer and the second intermediate layer in the visible light band is greater than or equal to 85%; 1.4) the transmittance of the dimming element in the visible light band can be adjusted within an adjustable range, the first transmittance is the maximum value of the adjustable range, and the second transmittance is the minimum value of the adjustable range; wherein the first transmittance is greater than or equal to 12%, and the second transmittance is less than or equal to 0.6%.

[0006] For example, taking the vehicle window assembly 100 as an example, the first glass body can be one of the glass bodies 110 and 120, and the second glass body can be the other of the glass bodies 110 and 120; the first intermediate layer can be one of the intermediate layers 140 and 150, and the second intermediate layer can be the other of the intermediate layers 140 and 150.

[0007] In the present application, by coordinating the light transmittance of each layer in the vehicle window assembly, it is possible to effectively take into account the usage requirements of the vehicle window assembly in different scenarios when the dimming performance of the dimming element is limited.

[0008] In some possible implementations, the vehicle window assembly (100) may further include a third intermediate layer (160), which may be disposed in a peripheral area of ​​the first area. 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); and the receiving space may be used to accommodate a sandwich structure formed by the first intermediate layer (140), the dimming element (130), and the second intermediate layer (150).

[0009] In this application, the coordination of multiple intermediate layers can reduce the amount of water, oxygen, dust, and other substances that intrude into the dimming element. Using a narrower third intermediate layer can prevent interference from water, oxygen, and other substances with the dimming element. This approach helps reduce the width of the shielding layer and minimizes the deterioration of the vehicle's appearance caused by the dimming element.

[0010] In some possible implementations, a shielding layer (171, 172) may be provided on the first surface of the first glass body (110) and / or the second glass body (120). An end of the shielding layer (171, 172) away from the first region may correspond to an end of the peripheral region, and an end of the shielding layer (171, 172) close to the first region may correspond to an end of the dimming element (130).

[0011] In this application, by setting a shielding layer, it can play a beautifying role.

[0012] In some possible implementations, the dimming element (130) may include a main body (131) and a tape assembly (132). The main body (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 the first intermediate layer (150), and the third surface (1312) may be bonded to the second intermediate layer (160). The first end of the tape assembly (132) may be bonded to the second surface (1311), the second end of the tape assembly (132) may be bonded to the third surface (1312), and the middle portion of the tape assembly (132) may be bonded to the side of the main body (131).

[0013] In the present application, by providing a tape assembly, it is possible to further prevent water, oxygen, dust and other substances from invading the dimming element from the side, and to further improve the water resistance and oxygen resistance of the vehicle window assembly.

[0014] In some possible implementations, the tape assembly (132) may include a plurality of tapes, wherein two adjacent tapes in the plurality of tapes are 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).

[0015] In some possible implementations, the dimming element (130) may include an electrode, and the vehicle window assembly (100) may further include a wiring harness assembly (135). The wiring harness assembly (135) may include a flexible circuit board (FPC); the FPC may be connected to the electrode of the dimming element (130); and an end of the FPC close to the dimming element (130) may be disposed between the first glass body (110) and the second glass body (120).

[0016] Since the flexible circuit board is thin and easily deformed, in this application, by connecting the flexible circuit board with the electrodes of the dimming element, it is possible to avoid the part of the wiring harness assembly between the two glass bodies from damaging the glass body.

[0017] In some possible implementations, the vehicle window assembly (100) may further include a wiring harness fixing assembly (180); the wiring harness fixing assembly (180) may be disposed on an inner surface of the vehicle window assembly (100), and an end of the FPC away from the dimming element (130) may be connected to the wiring harness fixing assembly (180).

[0018] Some types of window assemblies may be repeatedly raised and lowered during use. In this application, the wiring harness fixing assembly is arranged on the inner surface of the window assembly (i.e., the surface of the window assembly facing the cabin), and the FPC is arranged on the wiring harness fixing assembly, which helps to extend the service life of the wiring harness assembly.

[0019] In some possible implementations, the dimming element (130) includes an electrochromism (EC) film.

[0020] In this application, EC film is used as a dimming element. On the one hand, its dimming rate can achieve a wider 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 a color deviation from the actual scene, nor will it bring additional oppression and restraint to the user.

[0021] 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%.

[0022] In this application, by further controlling the performance of each component, the window assembly can be guaranteed to have consistent light transmission performance during mass production.

[0023] In some possible implementations, within a first temperature range, the first light transmittance is greater than or equal to 12%, and the second light transmittance is less than or equal to 0.6%; the first temperature range may include -10 degrees Celsius to 50 degrees Celsius.

[0024] In a second aspect, a control method is provided. This method can be executed by a control device of a vehicle window assembly with a dimming function, or by a component of the control device (such as a chip, processor, processing circuit, etc.), or by a system or vehicle incorporating the control device.

[0025] The method comprises: obtaining dimming indication information; and controlling the light transmittance of a vehicle window assembly in a visible light band according to the dimming indication information.

[0026] Exemplarily, the vehicle window assembly may be the vehicle window assembly in the above-mentioned first aspect and any possible implementation thereof; or, it may also be other vehicle window assemblies with a dimming function.

[0027] In some possible implementations, the dimming indication information may be used to indicate a rotation direction of the dimming knob and a duration of rotation in the rotation direction. Controlling the transmittance of the window assembly in the visible light band based on the dimming indication information may include adjusting the transmittance of the window assembly in the visible light band based on the rotation direction and the duration.

[0028] Exemplarily, the vehicle window assembly may include a dimming element, the transmittance of the dimming element in the visible light band can be adjusted within an adjustable range, the first transmittance is the maximum value of the adjustable range, and the second transmittance is the minimum value of the adjustable range.

[0030] In the present application, based on the rotation direction of the dimming knob and the duration of rotation in that direction, the light transmittance of the vehicle window assembly can be directly adjusted to the maximum or minimum value, which can simplify the user's adjustment process of the light transmittance.

[0031] In some possible implementations, the dimming instruction information may include first manipulation information, which may be used to instruct adjustment of the transmittance of the dimming element to a first transmittance or a second transmittance. Controlling the transmittance of the window assembly in the visible light band based on the dimming instruction information may include adjusting the transmittance of the dimming element in the visible light band to the first transmittance or the second transmittance based on the first manipulation information.

[0032] In the present application, the transmittance is adjusted to the maximum or minimum value with one click according to the first manipulation information, which helps to simplify the user's adjustment process of the transmittance.

[0033] In some possible implementations, the dimming indication information may be used to indicate the ambient temperature of the window assembly. Controlling the transmittance of the window assembly in the visible light band based on the dimming indication information may include: adjusting the transmittance of the window assembly in the visible light band based on the ambient temperature; and / or determining an adjustment parameter for the transmittance of the window assembly in the visible light band based on the ambient temperature.

[0034] In the present application, adjusting the light transmittance of the vehicle window assembly and / or the light transmittance adjustment parameters according to the ambient temperature is beneficial to ensuring the dimming performance and service life of the vehicle window assembly.

[0035] In some possible implementations, determining the adjustment parameters of the vehicle 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 the first transmittance to the second transmittance; or, within a second temperature range, using a second value as the ratio of the first transmittance to the second transmittance.

[0036] In the present application, different ratios are set for the first light transmittance and the second light transmittance in different temperature ranges, which is beneficial to ensuring the service life of the dimming element while meeting usage requirements.

[0037] In 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, setting the first light transmittance to be within a range greater than or equal to 13% and less than 15%, and setting the second light transmittance to be within a range greater than 0.25% and less than or equal to 0.45%; when the ambient temperature is within a second temperature range, setting the first light transmittance to be within a range greater than or equal to 9% and less than 11%, and setting the second light transmittance to be within a range greater than 0.4% and less than or equal to 0.6%; or, when the ambient temperature is within a third temperature range, setting the first light transmittance to be within a range greater than or equal to 6% and less than 8%, and setting the second light transmittance to be within a range greater than 0.25% and less than or equal to 0.45%.

[0038] In the present application, different values ​​are set for the first light transmittance and the second light transmittance in different temperature ranges, which is beneficial to ensuring the service life of the dimming element while meeting usage requirements.

[0039] In some possible implementations, the first temperature range may include a temperature interval of -10 degrees Celsius to 50 degrees Celsius; the second temperature range may include a temperature interval of 50 degrees Celsius to 65 degrees Celsius; and the third temperature range may include a temperature interval of -20 degrees Celsius to -10 degrees Celsius.

[0040] In some possible implementations, the window assembly is in a first light transmission position. Adjusting the light transmittance of the window assembly in the visible light band according to the ambient temperature may include adjusting the light transmittance of the window assembly in the visible light band from a third light transmittance to a fourth light transmittance when the ambient temperature changes from the first ambient temperature to the second ambient temperature. At the first ambient temperature, the first light transmission position corresponds to the third light transmittance; at the second ambient temperature, the first light transmission position corresponds to the fourth light transmittance.

[0041] In the present application, by adjusting the light transmittance, the window assembly can be maintained at a certain light transmittance level even if the ambient temperature changes, thereby achieving the effect of maintaining the light transmittance level.

[0042] In some possible implementations, the dimming indication information may include cabin mode information. Controlling the transmittance of the vehicle window assembly (100) in the visible light band according to the dimming indication information may include: adjusting the transmittance of the vehicle window assembly (100) in the visible light band according to the cabin mode information, or limiting the adjustment of the transmittance of the vehicle window assembly.

[0043] In the present application, the light transmittance of the window assembly is controlled according to the cockpit mode, so that the light transmittance state of the window assembly and the cockpit mode can be linked together, thereby enriching the user experience.

[0044] In a third aspect, a method for preparing a vehicle window assembly is provided.

[0045] Exemplarily, the vehicle 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, 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 the 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%.

[0077] The technical solution in this application will be described below with reference to the accompanying drawings.

[0078] For example, Figure 1Schematic diagram of a vehicle provided in an embodiment of the present application. Figure 1 As shown, 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 .

[0079] When vehicle 10 leaves the factory, the front window assembly 11, rear window assembly 12, and triangular window assembly 13 may all be transparent and have high light transmittance. While using vehicle 10, users may apply film to the inside of the window assembly to enhance cabin privacy, for example. If this approach is adopted, the windows will have low light transmittance regardless of the vehicle's usage scenario. However, in certain usage scenarios, users may desire higher light transmittance from the windows (for example, when they want to view the scenery outside the vehicle); in these cases, this approach will not meet the user's needs.

[0080] 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 install dimming films on car window glass to meet the needs of use in different scenarios.

[0081] On the one hand, for the sunroof assembly, the purpose of dimming is mainly to avoid direct sunlight, and there is no need to require the dimming film to achieve extremely low transmittance. For the window glass, the goal of dimming is to provide privacy for the cabin under dark conditions and avoid affecting the user's field of view under bright conditions. The difference in the purpose of use leads to different requirements for dimming performance. Among them, the bright state can be understood as the dimming film / glass assembly with dimming function (such as the sunroof assembly with dimming function, window assembly, etc.) working with a higher transmittance within the adjustable range of transmittance; correspondingly, the dark state can be understood as working with a lower transmittance within the adjustable range of transmittance.

[0082] On the other hand, although the transmittance of the dimming film can vary within an adjustable range, due to the limitations of the dimming film's performance and cost considerations, the ratio between the maximum and minimum values ​​of the adjustable range (referred to as the dimming contrast ratio) is often relatively small (for example, the ratio can be less than 20), making it difficult to achieve a larger dimming contrast ratio (such as 60, 100, etc.). Within the adjustable range, if the dimming film cannot achieve an extremely low transmittance, the need for privacy protection cannot be met (for example, even if the dimming film is in a dark state, the lit mobile phone screen in the cabin and the user in the cabin can still be observed through the car window from outside the car); if the dimming film can achieve an extremely low transmittance, due to the limitations of the dimming contrast ratio, it will not be able to achieve a higher transmittance in the bright state, which will interfere with the user's field of vision. In fact, the user in the cabin may even feel restrained and oppressed due to insufficient ambient light.

[0083] In view of this, an embodiment of the present application provides a vehicle window assembly that can meet the needs of different usage scenarios by coordinating the light transmittance of various parts in the vehicle window assembly.

[0084] For example, Figure 2 1 is a schematic structural diagram of a vehicle window assembly 100 provided in an embodiment of the present application. The vehicle window assembly 100 may correspond to a front vehicle window assembly 11, a rear vehicle window assembly 12 or a triangular vehicle window assembly 13.

[0085] like Figure 2 As shown, the vehicle window assembly 100 may include a glass body 110 , a glass body 120 , a dimming element 130 , and an intermediate layer.

[0086] The dimming element 130 can be disposed in the first region of the vehicle window assembly; in the thickness direction of the vehicle 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 via an intermediate layer 140, and can be bonded to the glass body 120 via an intermediate layer 150.

[0087] For example, the dimming element 130 can implement dimming using electrochromic, liquid crystal (LC), or other methods. For example, the dimming element 130 can be an EC film. In another example, the dimming element 130 can be a polymer dispersed liquid crystal (PDLC) film. In another example, the dimming element 130 can be a dye liquid crystal (DLC) film.

[0088] Because the window assembly 100 utilizes a sandwich structure within the first region, the state of the window assembly 100 in both the bright and dark states is affected not only by the transmittance of the dimming element but also by various factors, such as the transmittance and color of the glass and the interlayer. Furthermore, due to the dimming contrast limitations of the dimming film, an improperly adjusted transmittance range for the film will make it difficult for the window assembly 100 to meet the demands of both bright and dark states.

[0089] The transmittance of the glass body 110 in the visible light band is denoted as a; the transmittance of the glass body 120 in the visible light band is denoted as b; the transmittance of the intermediate layer 140 in the visible light band is denoted as c; the transmittance of the intermediate layer 140 in the visible light band is denoted as d; the adjustable range of the transmittance of the dimming element 130 in the visible light band is denoted as the dimming interval M, the maximum value of the dimming interval M can be denoted as e, and the minimum value of the dimming interval M can be denoted as f.

[0090] In order to meet the usage requirements of the vehicle window assembly 100 in different scenarios, the vehicle window assembly 100 can meet the following conditions: 1.1) The glass bodies 110 and 120 are made of transparent glass; 1.2) The transmittance a of the glass body 110 is greater than 83% and less than or equal to 93%; 1.3) The transmittance of the glass body 120 is greater than 83% and less than or equal to 93%; 1.4) The transmittances c and d are greater than or equal to 85%; 1.5) For the dimming range M, the transmittance e is greater than or equal to 12%, and the transmittance f is less than or equal to 0.6%.

[0091] In some possible implementations, the dimming element 130 may have different adjustable ranges within different temperature ranges. Condition 1.5) above may mean that within the global operating temperature range, or within a portion of the operating temperature range (e.g., the primary operating temperature range, the secondary operating temperature range, etc.), the transmittance e may be greater than or equal to 12%, and the transmittance f may be less than or equal to 0.6%.

[0092] The main operating temperature range, the secondary operating temperature range, and the global operating temperature range of the window assembly 100 may vary depending on the intended sales area of ​​the vehicle (such as Europe, America, Asia, etc.). Assume that the main operating temperature range and the global operating temperature range are the first temperature range. For example, the first temperature range may be a temperature range of 15 degrees Celsius (℃) to 45 degrees Celsius. For another example, the first temperature range may be a temperature range of 10℃ to 50℃. For another example, in the first temperature range, for the dimming interval M, the transmittance e may be 12.5%, 14%, or 13%; f may be 0.35%, 0.5%, or 0.6%. For another example, the adjustable range of the first temperature range and / or transmittance may be set according to actual usage requirements; for another example, the glass bodies 110 and 120 may be transparent white glass.

[0093] For example, the adjustable range of the dimming element 130 may vary within different temperature ranges; that is, the maximum and / or minimum values ​​of the dimming range M may correspond to the ambient temperature of the dimming film. For example, within the temperature range of 10°C to 50°C, the transmittance e may be 14%; while within the temperature range of 50°C to 65°C, the transmittance e may be set to 10%.

[0094] In practical scenarios, if glass 110 and / or 120 is another type of glass, such as frosted glass, when a user observes objects outside the vehicle from inside the cabin through the window assembly 100 in bright light mode, the frosted glass will provide a "filter," obscuring the user's view of objects outside the vehicle. If the transmittance of glass 110 and / or 120 is less than 83%, to meet the requirements of bright light mode, the maximum transmittance e of dimming range M must be set to a higher value. However, due to the limitations of dimming contrast, the minimum transmittance f must be increased accordingly, making it difficult for the window assembly to meet the privacy protection requirements in dark light mode. If the transmittance of glass 110 and / or 120 exceeds 93%, to meet the requirements of dark light mode, the minimum transmittance f of dimming element 130 must be set to a lower value. However, due to the limitations of dimming contrast, the maximum transmittance e must be reduced accordingly, making it difficult for the window assembly to meet the requirements of bright light mode.

[0095] In the embodiment of the present application, by coordinating the performance of each layer in the vehicle window assembly, it is possible to effectively take into account the usage requirements of the vehicle window assembly in different scenarios when the dimming performance of the dimming element is limited.

[0096] In actual mass production, the performance of the same type of components from different batches and production dates will inevitably vary. Adopting inappropriate control methods will lead to serious fluctuations in the light transmission performance of the same type of window assemblies.

[0097] In some possible implementations, in order to ensure that the same type of window assemblies have consistent light transmittance performance during mass production, the window assembly 100 may meet the following conditions: 2.1) the transmittance a may be greater than 88% and less than or equal to 92%; 2.2) the transmittance b may be greater than 88% and less than or equal to 92%; 2.3) the transmittances c and d may be greater than or equal to 88%; 2.4) the transmittance e may be greater than or equal to 14% and less than 17%; 2.5) the transmittance f may be greater than 0.3% and less than or equal to 0.5%.

[0098] For example, in mass production, the design value of transmittance a can be set at 90.3%, and the transmittance a can be allowed to fluctuate within ±1% of 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 repeated here.

[0099] In the embodiment of the present application, by further controlling the performance of each component, it is possible to ensure that the vehicle window assembly has consistent light transmission performance during mass production.

[0100] Furthermore, when configuring dimming functions for vehicle window assemblies, in addition to considering whether the dimming performance can meet the needs of different usage scenarios, it may also be necessary to consider the impact of the dimming components and related structures on the appearance of the window / vehicle. For example, dimming components such as EC films and PDLC films often have electrodes. To prevent these electrodes and related structures from being exposed to the user's field of view, a shielding layer can be added to the glass to conceal these structures.

[0101] In some possible implementations, the vehicle window assembly 100 may further include a shielding layer disposed on the first surface of the glass body. The end of the shielding layer away from the first area may correspond to the end of the peripheral area, and the end of the shielding layer closer to the first area 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 closer to the dimming element may correspond to the first surface. For another example, assuming that the glass body 120 is disposed closer to the cabin, a shielding layer 173 may be disposed on the surface of the glass body 120 closer to the cabin, and the shielding layer 172 may not be required. In this case, for the glass body 120, the surface closer to the dimming element may correspond to the first surface. The shielding layers 171, 172, and 173 can be used to shield the gap between the dimming element 130 and the intermediate layer 160, and structures such as the electrodes of the dimming element 130. When the dimming element 130 is provided with a tape assembly, the shielding layers 171, 172, and 173 can also be used to shield the tape assembly. For another example, the end of the shielding layer away from the first area can be in the same position as the end of the peripheral area, or a certain gap (for example, 3 or 5 mm) can be maintained between the end of the peripheral area. Similarly, the end of the shielding layer close to the first area can be in the same position as the end of the dimming element, or a certain gap can be maintained between the two.

[0102] In the embodiment of the present application, a shielding layer is provided to achieve a beautifying effect.

[0103] While glass assemblies like sunroofs with dimming functions may also be equipped with a corresponding shielding layer, compared to other glass assemblies, vehicle window assemblies are more likely to be within the user's field of vision, making them more perceptible to the user. When dimming elements such as dimming film are installed in other glass assemblies, the impact of the shielding layer on the vehicle's aesthetics can be less of a concern. However, when dimming elements are installed in vehicle window assemblies, the degradation of the vehicle's aesthetics by the shielding layer cannot be ignored. From the user's perspective, improper installation of dimming film will seriously degrade the vehicle's aesthetics.

[0104] Furthermore, due to their different vehicle placements, the window and sunroof assemblies face different physical and chemical environments. Sunroof assemblies often have a convex shape, with a high center and low sides, and vehicles often incorporate sealing structures / devices on the sides of the sunroof glass. However, the sides of the window assembly may be exposed to rain, dust, and other environmental factors. For dimming components like EC mirrors, whose performance is easily affected by substances like water and oxygen, an inappropriate window assembly design can compromise both the aesthetics and durability of the assembly.

[0105] In some possible implementations, the vehicle window assembly 100 may further include an intermediate layer 160. The intermediate layer 160 may be disposed in a peripheral region of the first region. The intermediate layer 160 may be used to bond the glass bodies 110 and 120. The intermediate layer 160 and the glass bodies 110 and 120 may also form a receiving space for accommodating the sandwich structure formed by the dimming element 130, the intermediate layer 140, and the intermediate layer 150.

[0106] For example, Figure 2 As shown, the intermediate layer 160 can form a frame structure, and the dimming element 130 and the intermediate layers 140 and 150 can be disposed within the frame structure. That is, for the vehicle window assembly 100, in the first region, the vehicle window assembly 100 can include a five-layer sandwich structure consisting of the glass body 110, the intermediate layer 140, the dimming element 130, the intermediate layer 150, and the glass body 120; while in the peripheral region of the first region, the vehicle window assembly 100 can include a three-layer sandwich structure consisting of the glass body 110, the intermediate layer 160, and the glass body 120.

[0107] In some embodiments, the width of the middle layer 160 may be less than or equal to 15 mm or 18 mm.

[0108] Assuming that a five-layer sandwich structure is also used in the peripheral area (for example, the intermediate layers 140 and 150 are extended to the edge of the window assembly 100, and another intermediate layer is provided in the peripheral area with the dimming element 130 to bond the intermediate layers 140 and 150), when water, oxygen, dust, etc. invade the window assembly, the interlayer structure (i.e., the bonding gap between each two layers) will have four intrusion points.

[0109] During the use of the vehicle window assembly, there will inevitably be interaction forces between the various layers; under long-term use, these interaction forces will deteriorate the bonding gaps, making it easier for water, oxygen, dust and other substances to penetrate into the interior of the vehicle window assembly.

[0110] If the five-layer sandwich structure is also used in the outer area, to ensure the durability of the window assembly, the width of the outer area (or the width of the intermediate layer parallel to the dimming element) needs to be set sufficiently large (for example, 50 mm or more) to ensure a strong bonding gap at the edge to prevent water, oxygen, and other substances from invading the area where the dimming element 130 is located. This width setting is particularly important for dimming elements such as EC films, whose performance is easily affected by substances such as water and oxygen. However, this will result in the width of the shielding layer being too large, which will seriously affect the vehicle's appearance.

[0111] Regarding the vehicle window assembly 100, on the one hand, in the peripheral region, the glass bodies 110 and 120 are bonded together by the intermediate layer 160. When substances such as water, oxygen, and dust intrude into the vehicle window assembly 100, the number of interlayer structures where they can intrude is reduced to two. On the other hand, when substances such as water, oxygen, and dust intrude into the peripheral region and further into the area where the dimming element 130 is located, the portion of these substances that have already intruded into the peripheral region must be further distributed across the multiple interlayer structures in the first region, and their intrusion direction must be changed before they can intrude into the area where the dimming element 130 is located. This further reduces the amount of substances that can intrude into the area where the dimming element 130 is located.

[0112] In this embodiment, the coordination of multiple intermediate layers reduces the amount of water, oxygen, dust, and other substances that intrude into the area where the dimming element 130 is located. Using a narrower intermediate layer 160 prevents the effects of water, oxygen, and other substances on the dimming element. This approach helps reduce the width of the shielding layer, minimizing the deterioration of the vehicle's appearance caused by the dimming element, achieving a balance between practicality and aesthetics.

[0113] For example, the first area may be located at the center of the vehicle window assembly 100. For example, when the vehicle window assembly 100 corresponds to the triangular window assembly 13, the first area may be located at the center of the triangular window.

[0114] In some possible implementations, the first area may also be close to an edge area of ​​a certain side of the window assembly 100. The following takes the window assembly 100 corresponding to the rear window assembly 12 as an example. Figure 3 The first region and the edge region of the first region are exemplified.

[0115] For example, Figure 3 This is a schematic diagram of the area division of the vehicle window assembly provided in an embodiment of the present application.

[0116] In one embodiment, for the liftable front / rear door window assembly, the upper portion thereof can be exposed outside the sheet metal of the door, and the lower portion thereof will be blocked by the sheet metal of the door. Figure 3As shown in (a) of FIG. , region A can be offset from the center of the vehicle window and positioned near the edge of the upper portion of the vehicle window assembly; the remaining area outside region A can constitute region B. The 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 first region described above, and region B can correspond to the peripheral area of ​​the first region.

[0117] In another embodiment, to reduce the weight and cost of the vehicle window assembly, the aforementioned region B can be further divided into region C and region D. Region D can be understood as the portion of the lower half of region B that is not within the user's field of view. An intermediate layer 160 can be placed in region C, bonding the upper halves of the two glass bodies 110 and 120 together via intermediate layer 160. To improve the reliability of the vehicle window assembly, an intermediate layer E can be placed 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 periphery of the first region.

[0118] The first area of ​​the vehicle window assembly 100 and the peripheral area of ​​the first area may also refer to corresponding areas of the glass bodies 110 and 120 .

[0119] In some possible implementations, the dimming element 130 may include a main body 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 131, and the bottom of the tape assembly 132 may be attached to the lower surface 1312 of the main body 131.

[0120] Assume that the main body 131 adopts a multi-layer membrane structure; in this case, the upper surface 1311 and the lower surface 1312 may belong to different membranes. Figure 4 For example, Figure 4 Adopted with Figure 2 (b) The same or similar perspective.

[0121] For example, Figure 4 Schematic diagram of the structure of the dimming element 130 provided in an embodiment of the present application.

[0122] In one embodiment, the tape assembly 132 may be a single tape; the tape assembly 132 may be C-shaped in cross section. Figure 4 As shown in (a), the top of the tape is in contact with the upper surface 1311 of the main body 131, the bottom of the tape is in contact with the lower surface 1312 of the main body 131, and the middle part of the tape can be in contact with the side of the main body 131.

[0123] In another embodiment, the tape assembly 132 may include a plurality of tapes; adjacent tapes may be bonded to each other. Figure 3 As shown in (b), the tape assembly 132 may include a tape 1321 and a tape 1322; the top of the tape 1321 is in contact with the upper surface 1311 of the main body 131, and the bottom of the tape 1321 is in contact with the top of the tape 1322; the bottom of the tape 1322 is in contact with the lower surface 1312 of the main body 131.

[0124] In the embodiment of the present application, by providing a tape assembly, water, oxygen, dust and other substances can be further prevented from invading the dimming element 130 from the side, which can further improve the water resistance and oxygen resistance of the vehicle window assembly.

[0125] For example, the vehicle window assembly 100 may further include a wiring harness assembly 135 , and the wiring harness assembly 135 may be connected to the electrodes of the dimming element.

[0126] In vehicle window assemblies, the surfaces of the glass bodies 110 and 120 are often curved, and the gap between them is relatively small. When using a conventional wiring harness to connect the electrodes of the dimming element 130, a portion of the wiring harness inevitably ends up between the two glass bodies. Improperly configured wiring harness diameters can damage the glass bodies, and the harness can easily vibrate due to vehicle vibrations, generating noise.

[0127] 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 ; and one end of the FPC close to the dimming element 130 may be disposed between the glass bodies 110 and 120 .

[0128] Since the flexible circuit board is relatively thin and easily deformed, in the embodiment of the present application, by connecting the flexible circuit board to the electrodes of the dimming element 130 , damage to the glass body caused by the wiring harness assembly can be avoided.

[0129] For example, the window assembly 100 may further include a wiring harness securing assembly 180. For example, the wiring harness securing assembly 180 may be disposed on the inner surface of the window assembly 100. Since the front and rear door glass may be raised and lowered repeatedly during use, disposing the wiring harness securing assembly 180 on the inner surface of the window assembly 100 (i.e., the surface of the window assembly 100 facing the cabin) and securing the wiring harness assembly 135 to the wiring harness securing assembly 180 can help extend the service life of the wiring harness assembly.

[0130] For example, Figure 5 This is a schematic diagram of an arrangement of a wiring harness assembly provided in an embodiment of the present application.

[0131] like Figure 5As shown, the wiring harness fixing assembly 180 can be bonded to the inner surface of the vehicle window glass; the wiring harness assembly 135 can include a flexible circuit board 1351 and a wiring harness 1352. A portion 1353 of the flexible circuit board 1351 can be positioned 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 attached to the wiring harness fixing assembly 180 by bonding, clamping, or other means. The wiring harness 1352 can be used to connect to the entire vehicle wiring harness.

[0132] In some possible implementations, the intermediate layers in the vehicle window assembly 100 , such as the intermediate layers 140 , 150 , 160 , etc., may be made of materials suitable for laminated glass, such as polyvinylbutyral (PVB) and SGP film.

[0133] In some possible implementations, the dimming element 130 may include an EC film.

[0134] In actual scenarios, although PDLC film, DLC film and spectral power distribution (SPD) film can also achieve dimming, compared with EC film, PDLC film has a higher haze in both bright and dark states, and will appear frosted glass; even in the bright state, it will cause a sense of restraint and oppression to users in the cabin; DLC film will show a certain color in the bright and intermediate states, and will provide a layer of "filter", causing the color of the objects observed by the user to deviate; SPD film, on the one hand, will appear blue in the bright and dark states, and on the other hand, its operating voltage is relatively high (such as 110 volts or 120 volts), which poses a safety hazard.

[0135] In the embodiment of the present application, EC film is used as a dimming element. On the one hand, its dimming rate can achieve a wider 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 a color deviation from the actual scene, nor will it bring additional oppression and restraint to the user.

[0136] Combination of the above Figures 1 to 5 The window assembly provided in the embodiment of the present application is exemplarily described. The embodiment of the present application also provides a control method, which is as follows: Figures 6 to 8 For example illustration.

[0137] For example, Figure 6 It is a schematic flow chart of a control method provided in an embodiment of the present application.

[0138] The method 600 may be executed by a control device of a vehicle window assembly with a dimming function, or by a component of the control device (such as a chip, a processor, a processing circuit, etc.), or by a system or vehicle including the control device. For example, the vehicle window assembly with a dimming function may be the vehicle window assembly 100, or may be another vehicle window assembly with a dimming function. The method 600 may include:

[0139] S610: Obtain dimming instruction information.

[0140] In some embodiments, the control device of the window assembly may be provided with a dimming knob and / or a dimming button. The dimming instruction information may include operation information regarding the dimming knob and / or button. For example, turning the dimming knob clockwise may indicate increasing the light transmittance of the window assembly; turning the dimming knob counterclockwise may indicate decreasing the light transmittance of the window assembly.

[0141] In some further embodiments, the dimming indication information may include ambient temperature information. For example, to ensure the performance and service life of the dimming element, different dimming performance settings may be set for the dimming element in different temperature ranges. The transmittance of the window assembly can be adjusted by adjusting the transmittance of the dimming element in the visible light band based on the ambient temperature information.

[0142] In some other embodiments, the dimming indication information may include cabin mode information. For example, a cabin may have multiple usage modes, such as movie viewing mode, rest mode, and normal mode. When the cabin is in movie viewing mode, it may be desirable for the window assembly to be at the lowest light transmittance within the adjustable range to prevent light from outside the vehicle from affecting viewing. When the cabin is in rest mode, it may be desirable for the window assembly to be at a lower light transmittance to provide a dim environment for the cabin and promote sleep. When the cabin is in normal mode, it may be desirable for the window assembly to be at a higher light transmittance to provide the user with a clear view of the outside world. When part of the cabin is in children's mode, it may be undesirable for the user to adjust the light transmittance of the window assembly using a dimming knob, etc. The light transmittance of the window glass assembly can be controlled based on the cabin mode.

[0143] S620: Control the light transmittance of the window assembly in the visible light band according to the dimming instruction information.

[0144] For example, controlling the transmittance of a window assembly in the visible light band may include: adjusting the transmittance of the window assembly in the visible light band; and / or determining adjustment parameters for the transmittance of the window assembly in the visible light band. For example, the transmittance of the window assembly in the visible light band may be adjusted based on the rotation direction of a dimming knob or the operation of a dimming button. In another example, transmittance may be divided into multiple levels, and the transmittance level of the window assembly may be increased or decreased accordingly based on user operation of the dimming knob or dimming button, thereby adjusting transmittance. In another example, the adjustable range of a light-transmitting element may be adjusted.

[0145] For example, controlling the transmittance of the window assembly in the visible light band may also include limiting adjustment of the transmittance of the window assembly in the visible light band. For example, when the cabin is in child mode, adjustment of the transmittance of the window assembly may be limited.

[0146] In some possible implementations, the dimming indication information may indicate a rotation direction of the dimming knob and a duration of the dimming knob being rotated in the rotation direction. Controlling the transmittance of the window assembly in the visible light band based on the dimming indication information may include adjusting the transmittance of the window assembly in the visible light band based on the rotation direction and duration of the dimming knob.

[0147] For example, when the dimming knob is rotated in a first direction and the duration of rotation in this direction is less than a first threshold value (e.g., 1.5 seconds, 2 seconds), the transmittance of the window assembly in the visible light band can be increased based on the rotation amplitude of the dimming knob. For another example, when the dimming knob is rotated in a second direction and the duration of rotation in this direction is less than a second threshold value (e.g., 1.5 seconds, 2 seconds, 2.5 seconds), the 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 the other of the clockwise and counterclockwise directions. The first and second threshold values ​​can be the same or different.

[0148] For another example, when the dimming knob is rotated in a first direction and the duration of rotation in this 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 the adjustable range (i.e., the transmittance e). For another example, when the dimming knob is rotated in a second direction and the duration of rotation in this 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., the transmittance f).

[0149] That is to say, when the user turns the dimming knob, if the operation of the dimming knob is completed within a short time (less than the corresponding threshold), the transmittance of the car window glass can be adjusted based on the rotation direction and amplitude of the knob; if the dimming knob is continuously operated in a certain direction for a longer time, the transmittance of the car window glass can be adjusted to the maximum transmittance corresponding to that direction.

[0150] In the embodiment of the present application, the 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 can simplify the user's transmittance adjustment process.

[0151] In some possible implementations, when the number of intermittent rotations of the dimming knob in a 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 transmittance of the window assembly is suspended, and after a second time period (e.g., 5 or 10 seconds), the 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.

[0152] For example, when it is detected that the user has intermittently turned the dimming knob 10 times within 5 seconds, the adjustment of the transmittance of the window assembly is suspended, and after 20 seconds, the transmittance of the window assembly is adjusted according to the direction of the last rotation within this period.

[0153] Since the service life of a dimming element is often related to the number of dimming operations, in the embodiment of the present application, by delaying the adjustment of the transmittance of the window assembly, damage to the service life of the dimming element due to user misoperation can be avoided.

[0154] In some possible implementations, the dimming instruction information may include first manipulation information, which may 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 may be adjusted based on the first manipulation information.

[0155] For example, the control device for a vehicle window assembly may be provided with a button A and / or a button B. Activating button A may indicate a desire to adjust the light transmittance to the maximum value within an adjustable range, while activating button B may indicate a desire to adjust the light transmittance to the minimum value within the adjustable range. Depending on the activation of buttons A and B, the light transmittance of the vehicle window glass in the visible light band may be adjusted to the maximum or minimum value within the adjustable range.

[0156] For example, the dimming knob can support pressing; when the current transmittance is greater than the middle value of the adjustable range, pressing the dimming knob can indicate 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 can indicate that the transmittance is expected to be adjusted to the minimum value of the adjustable range.

[0157] In the embodiment of the present application, the transmittance is adjusted to the maximum value or the minimum value with one click according to the first manipulation information, which helps to simplify the user's adjustment process of the transmittance.

[0158] In some possible implementations, the dimming indication information may be used to indicate the ambient temperature of the window assembly. Controlling the transmittance of the window assembly in the visible light band based on the dimming indication information may include: adjusting the transmittance of the window assembly in the visible light band based on the ambient temperature; and / or determining an adjustment parameter for the transmittance of the window assembly in the visible light band based on the ambient temperature.

[0159] For example, different dimming ranges can be set for the dimming element within different temperature ranges to prevent the dimming element from being damaged due to the mismatch between the dimming performance and the operating temperature. For example, when the ambient temperature is 20°C, the transmittance of the dimming element is 13% of the maximum value within the adjustable range corresponding to the temperature; when the ambient temperature changes to -10°C, the maximum value of the adjustable range changes to 9%. If the transmittance of the dimming element is still maintained at 13%, the dimming element may be damaged due to long-term inappropriate transmittance. After the ambient temperature changes, the transmittance can be adjusted accordingly according to the ambient temperature so that the transmittance of the dimming element can be within the corresponding adjustable range to ensure the service life of the dimming element.

[0160] In the embodiment of the present application, adjusting the light transmittance of the vehicle window assembly and / or the light transmittance adjustment parameters according to the ambient temperature is beneficial to ensuring the dimming performance and service life of the vehicle window assembly.

[0161] In some possible implementations, determining the adjustment parameters of the vehicle 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 the first transmittance to the second transmittance; or, within a second temperature range, using a second value as the ratio of the first transmittance to the second transmittance.

[0162] For example, different dimming performances can be set for the dimming element in different temperature ranges to prevent the dimming element from being damaged due to the 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 the transmittance e and f can be 35 to 40 times; in the temperature range of -20℃ to -10℃, the ratio of the transmittance e and f can be 15 to 20 times; in the range of 50℃ to 65℃, the ratio of the transmittance e and 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 range of -20℃ to -10℃ and the range of 50℃ to 65℃ can correspond to the second temperature range.

[0163] In the embodiment of the present application, different ratios are set for the first light transmittance and the second light transmittance in different temperature ranges, which is beneficial to ensuring the service life of the dimming element while meeting usage requirements.

[0164] In 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, setting the first light transmittance to be within a range greater than or equal to 13% and less than 15%, and setting the second light transmittance to be within a range greater than 0.25% and less than or equal to 0.45%; when the ambient temperature is within a second temperature range, setting the first light transmittance to be within a range greater than or equal to 9% and less than 11%, and setting the second light transmittance to be within a range greater than 0.4% and less than or equal to 0.6%; or, when the ambient temperature is within a third temperature range, setting the first light transmittance to be within a range greater than or equal to 6% and less than 8%, and setting the second light transmittance to be within a range greater than 0.25% and less than or equal to 0.45%.

[0165] In some possible implementations, the first temperature range may include a temperature interval of -10 degrees Celsius to 50 degrees Celsius; the second temperature range may include a temperature interval of 50 degrees Celsius to 65 degrees Celsius; and the third temperature range may include a temperature interval of -20 degrees Celsius to -10 degrees Celsius.

[0166] In the embodiment of the present application, different values ​​are set for the first light transmittance and the second light transmittance in different temperature ranges, which is beneficial to ensuring the service life of the dimming element while meeting usage requirements.

[0167] In some possible implementations, the window assembly is in a first light transmittance setting. Adjusting the light transmittance of the window assembly in the visible light band based on the ambient temperature may include adjusting the light transmittance of the window assembly in the visible light band from a third light transmittance to a fourth light transmittance when the ambient temperature changes from the first ambient temperature to the second ambient temperature. At the first ambient temperature, the first light transmittance setting may correspond to the third light transmittance; at the second ambient temperature, the first light transmittance setting may correspond to the fourth light transmittance. For example, the first light transmittance setting may be any setting; the third light transmittance setting may be any value; and the fourth light transmittance setting may be any value different from the third light transmittance.

[0168] In the embodiment of the present application, by adjusting the transmittance, the window assembly can be maintained at the first light transmission gear even if the ambient temperature changes; the light transmission gear can be prevented from changing with the change of the ambient temperature, and the effect of maintaining the light transmission gear can be achieved.

[0169] The following is an exemplary description of the corresponding relationship between the adjustable range and the temperature range in conjunction with Table 1.

[0170] Table 1

[0171] Ambient temperature T Adjustable range T＜-20℃ Low temperature protection, limited dimming function -20℃～-10℃ 0.55％～10％ -10℃～50℃ 0.4％～13.5％ 50℃～65℃ 0.4％～7.5％ T＞65℃ High temperature protection, limited dimming function

[0172] For example, if the ambient temperature is too severe, controlling the dimming element to adjust its own transmittance within the adjustable range may reduce the service life of the dimming element. In view of this, as shown in Table 1, when the ambient temperature is less than -20°C, the dimming of the dimming element can be restricted to achieve low-temperature protection for the dimming element / window assembly; similarly, when the ambient temperature is above 65°C, the dimming of the dimming element can be restricted to achieve high-temperature protection for the dimming element / window assembly.

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

[0174] For example, when the ambient temperature is 40°C, the window assembly can be in the bright state, with its light transmittance at the maximum value of 13% within this temperature range. When the ambient temperature changes to the secondary operating temperature range of 50°C to 65°C, the window assembly's light transmittance can be automatically adjusted to the maximum value of 8% within this temperature range. When the ambient temperature further rises to the high-temperature protection temperature range, the high-temperature protection function can be automatically activated. This approach can meet user needs while extending the service life of the dimming element / window assembly.

[0175] For another example, assuming that the light transmission gear of the window assembly includes gear 1 to gear 5, the transmittance corresponding to each gear can be divided according to the adjustable range in Table 1. When the ambient temperature is 40°C, the light transmission gear of the window assembly is at gear 1; when the ambient temperature changes to the secondary operating temperature range of 50°C to 65°C, the ambient temperature change causes the adjustable range of the transmittance to change. If the transmittance is still maintained unchanged, the light transmission gear may change; thus, the transmittance can be adjusted according to the ambient temperature so that the light transmission gear of the window assembly can still be maintained at gear 1. In this way, the gear maintenance effect can be achieved, and the light transmission gear can be prevented from changing due to changes in ambient temperature. In this example, gear 1 can correspond to the first dimming gear.

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

[0177] In other embodiments, other methods may be used to divide low-temperature protection, high-temperature protection, primary operating temperature range, and secondary operating temperature range. For example, the low-temperature protection function is enabled only when the ambient temperature is below -30°C, and the high-temperature protection function is enabled 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 be different from that in Table 1. For example, in the temperature range of -10°C to 50°C, the corresponding adjustable range may be 0.35% to 14%.

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

[0180] The following combination Figure 7 and Figure 8 The controller in FIG. 6 is used to exemplify the method 600 .

[0181] For example, Figure 7 This is a schematic diagram of the structure of a controller provided in an embodiment of the present application.

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

[0183] For example, by rotating the knob 720 clockwise, the transmittance of the window assembly in the visible light band can be increased. For another example, by rotating the knob 720 counterclockwise, the transmittance of the window assembly for visible light can be reduced.

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

[0185] If the knob 720 is rotated clockwise, the visible light transmittance of the window assembly will increase, while if the knob 720 is rotated counterclockwise, the visible light transmittance of the window assembly will decrease. For example, if the knob 720 is rotated clockwise for more than 2 seconds, the visible light transmittance of the window assembly can be adjusted to the maximum value in the bright state. If the knob is rotated counterclockwise for more than 2 seconds, the visible light transmittance of the window assembly can be adjusted to the minimum value in the dark state.

[0186] For example, the knob supports push-to-adjust settings. For example, when the window assembly's visible light transmittance is at its maximum value within the adjustable range, pressing the button directly adjusts the transmittance to its minimum value within the adjustable range. Similarly, the reverse is true. In other words, pressing the button allows for a one-touch reversal of transmittance.

[0187] In some other embodiments, when the ambient temperature is detected to be within the low-temperature protection / high-temperature protection temperature range, the controller 700 may send an instruction to the vehicle controller to instruct it to disconnect the power supply to the dimming element. In this way, the low-temperature protection / high-temperature protection function can be implemented.

[0188] In some embodiments, multiple gears can be set according to the transmittance of the window assembly to visible light. The controller 700 may also include a gear indicator component 740. For example, the gear indicator component may include multiple indicator lights, and the user can know the current gear based on the number of indicator lights that are lit. For another example, assuming that clockwise rotation increases transmittance and counterclockwise rotation decreases transmittance, pressing and turning the button clockwise can increase the gear, and conversely, pressing and turning the button counterclockwise can reduce the gear. For another example, when the ambient temperature changes from one temperature range to another temperature range, the controller 700 can automatically adjust the transmittance of the window assembly according to the ambient temperature to achieve the effect of maintaining the gear.

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

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

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

[0192] In some possible implementations, the controller 800 may also support a gear maintaining function.

[0193] Combination of the above Figures 6 to 8 The control method provided in the embodiment of the present application is exemplarily described. The embodiment of the present application also provides a method for preparing a vehicle window assembly. Figure 9 For example illustration.

[0194] For example, Figure 9 900 is a schematic flow chart of a method for preparing a vehicle window assembly provided in an embodiment of the present application. The method 900 may include:

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

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

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

[0198] A suitable rubber ring can be selected according to 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 extraction.

[0199] S940, vacuum-exhausting the laminated glass assembly and the sealing sleeve by using an exhaust device under the first environmental condition, and allowing the laminated glass assembly and the sealing sleeve after vacuum-exhausting to stand still under the first environmental condition.

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

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

[0202] S950, under the second environmental condition, vacuum-exhausting the laminated glass assembly and the sealing sleeve after being left to stand under the first environmental condition by using an exhaust device, and removing the sealing sleeve after vacuum-exhausting.

[0203] The second environmental condition may be a high temperature and high pressure environment, such as an environmental temperature of 130° C. to 150° C. and an environmental pressure of 10-13 atmospheres.

[0204] Under high temperature and high pressure environment, vacuum extraction is performed to bond the edge portion of the intermediate layer to the glass body and / or dimming element, thereby achieving preliminary bonding of the laminated glass assembly.

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

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

[0207] In some embodiments, before the sealing sleeve is provided, the intermediate layer 160 may be provided at the peripheral area of ​​the first area of ​​the glass bodies 110 and 120 .

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