DETAILED DESCRIPTION

[0039] The following will describe the embodiments of the present disclosure with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present disclosure from the contents disclosed in this specification. The present disclosure may also be implemented or applied through different specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be understood that the preferred embodiments are merely illustrative of the present disclosure and are not intended to limit the scope of protection of the present disclosure.

[0040] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present disclosure. The illustrations only show components related to the present disclosure and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0041] The following will be combined with the accompanying drawings to clearly and completely describe some embodiments of the present disclosure. Obviously, the embodiments described are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0042] When describing some embodiments, the word "connected" and its derivatives may be used. The term "connected" should be understood broadly. For example, "connected" can mean fixed, removable, or integrated; it can be directly connected or indirectly connected through an intermediary. The embodiments disclosed herein are not necessarily limited to the contents of this document.

[0043] “At least one of A, B and C” has the same meaning as “at least one of A, B or C” and both include the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B and C.

[0044] With the widespread adoption of panoramic sunroofs in new energy vehicles in recent years, complaints about their poor thermal insulation have been widespread. Based on the triple principles of heat transfer (radiation, convection, and conduction), major OEMs have partnered with panoramic sunroof glass manufacturers to conduct research on thermal insulation.

[0045] Among related technologies, two mature products are currently available on the market to address heat insulation: conductive film-enhanced glass and electric sunshades. While these solutions offer some improvement, they also come with significant drawbacks: high-performance glass is expensive, and sunshades can create a sense of oppression within the vehicle.

[0046] Here, the film-layer conductivity-enhanced glass refers to glass with conductive properties obtained by coating a conductive film layer on the glass surface through a special process.

[0047] To enhance vehicle practicality, more and more vehicle models are being equipped with skylights. Skylights can broaden the user's field of view and enhance the vehicle's appearance. However, these systems also present some challenges. In hot, sunny weather, the skylights can overheat, leading to excessively high temperatures inside the vehicle. Heat radiation from the skylights can cause the surface temperature to reach over 65°C, making it extremely hot. Passengers' heads will feel noticeably hot within a fist's reach of the skylights, making them particularly uncomfortable for taller passengers. Furthermore, children can be burned if they accidentally touch the skylights while playing. Furthermore, due to the physical law that cold air sinks, the summertime drawbacks of skylights in conventional systems are unavoidable, no matter how high the air conditioning is turned.

[0048] To address the problem of skylight glass in related art causing excessively high vehicle temperatures in hot weather, current solutions involve modifying the skylight glass. For example, related art discloses a low-emissivity, heat-insulating insulating glass and a vehicle, comprising a glass body comprising a first glass substrate, a first reflective layer, a first polyvinyl butyral (PVB) film layer, a hollow layer, an ethylene-vinyl acetate copolymer (EVA) film layer, a second polyvinyl butyral film layer, a second glass substrate, and a second reflective layer, stacked in sequence. The first and second glass substrates are bonded at their facing edges with a sealant, forming a sealed cavity within the hollow layer. Inert gas is then introduced into the sealed cavity. However, since the skylight glass is an external component of the car body, its application scenarios are complex, and high requirements are placed on the skylight glass's light transmittance, wear resistance, heat resistance, radiation resistance, impact resistance, penetration resistance, and edge stress. Modification of the skylight glass may affect its comprehensive performance, requiring continuous exploration and improvement, resulting in a long R&D cycle.

[0049] On the other hand, liquid is injected into the skylight glass through preset control logic. For example, the related art discloses a sunshade skylight device and vehicle, which includes a skylight, a storage pot, a drive module, and a control module. A filling chamber is provided in the skylight. The storage pot is provided with a first liquid storage chamber and a second liquid storage chamber connected in series with the filling chamber. The first liquid storage chamber contains a first liquid, and the second liquid storage chamber contains a second liquid. The first and second liquids are opaque liquids of different colors. The skylight has a first shading mode, a second shading mode, and a transparent mode. In the first shading mode, the drive module, under the drive of the control module, drives the first liquid to flow into the filling chamber. In the second shading mode, the drive module, under the drive of the control module, drives the second liquid to flow into the filling chamber, thereby enabling the skylight to have the second shading mode. In the transparent mode, the filling chamber is empty. Although this solution can effectively enhance the thermal insulation performance of the skylight glass, its structure is complex and requires the addition of components such as a storage pot, a drive module, and a control module. This requires significant changes to the vehicle structure and is difficult to implement.

[0050] In view of this, some embodiments of the present disclosure provide a vehicle sunroof assembly 100 on one hand, referring to Figures 1 to 3, the vehicle sunroof assembly 100 includes a sunroof glass 11, a light-transmitting member 12 and an isolation member 13, the sunroof glass 11 is fixedly connected to the vehicle body, the light-transmitting member 12 is fixed to the inner side of the sunroof glass 11 through the isolation member 13, and an inflatable chamber 104 is formed between the inner side of the sunroof glass 11 and the outer side of the light-transmitting member 12, and the inflatable chamber 104 is filled with insulating gas.

[0051] In some embodiments, a light-transmitting member 12 is added to the inner side of the skylight glass 11, and an inflatable chamber 104 is formed between the inner side of the skylight glass 11 and the outer side of the light-transmitting member 12. The inflatable chamber 104 is filled with insulating gas. Since insulating gas is a poor conductor of heat and has good thermal insulation properties, it can further reduce the transfer of heat from the external environment into the vehicle interior, making the inner surface temperature of the vehicle skylight assembly 100 much lower than the external environment temperature. Due to the provision of the inflatable chamber 104, the "secondary heat radiation" from the inner surface of the skylight glass 11 to the vehicle interior is reduced, fundamentally solving the problem of "easy to burn the head" and "easy to burn the hands" of the skylight glass in the related art.

[0052] Furthermore, because the light-transmitting member 12 is connected (e.g., fixed) to the inner side of the sunroof glass 11 via the spacer 13, the connection is stable and reliable, eliminating the need for structural modifications to the sunroof glass in the related art. Furthermore, by adjusting the height of the spacer 13, the thickness of the air-filled chamber 104 between the inner side of the sunroof glass 11 and the outer side of the light-transmitting member 12 can be adjusted, which is convenient and quick, and can better meet the thermal insulation requirements of different vehicle models.

[0053] In some embodiments, the insulating gas is nitrogen or an inert gas, which is chemically stable and not prone to chemical reactions, ensuring reliability. Furthermore, nitrogen or an inert gas has a relatively low thermal conductivity, ensuring thermal insulation performance. For example, the insulating gas is nitrogen, which is low-cost and reliable.

[0054] In some embodiments, referring to Figures 2 and 5 , the isolation member 13 is provided with at least one inlet channel 105 and at least two exhaust channels 106 that communicate with the plenum chamber 104. When filled with insulating gas, the inlet channel 105 is connected to the gas source, one exhaust channel 106 is connected to the gas content detection assembly 140, and at least one exhaust channel 106 is connected to the outside air. Referring to Figures 3 and 5 , after the insulating gas is filled, the inlet channel 105 and the exhaust channel 106 are sealed by a plug 110.

[0055] An air inlet channel 105 connected to the gas source is used as the input port for the insulating gas, and at least one exhaust channel 106 is used as the air exhaust port in the inflation chamber 104. As the insulating gas is continuously injected, the original air in the inflation chamber 104 is squeezed and discharged to the outside from the exhaust channel 106. A gas content detection component 140 is used to detect the content of the insulating gas in the inflation chamber 104. When the content of the insulating gas in the inflation chamber 104 reaches a preset threshold, inflation is stopped and the gas source is turned off. Then, the connection between the gas source and the air inlet channel 105 on the isolation member 13, as well as the connection between the gas content detection component 140 and the exhaust channel 106 on the isolation member 13, are disconnected, and the air inlet channel 105 and the exhaust channel 106 are sealed with a plug cover 110, thereby effectively preventing gas leakage in the inflation chamber 104.

[0056] 2 , the at least one inlet channel 105 includes two inlet channels 105 spaced apart on the isolating member 13 . The at least two exhaust channels 106 include two exhaust channels 106 spaced apart on the isolating member 13 .

[0057] In some embodiments, referring to FIG. 3 and FIG. 4 , a flow restrictor 107 is provided (eg, fixed) in the air inlet passage 105 , and a plurality of pores 71 for allowing the insulating gas to pass through are uniformly provided in the flow restrictor 107 .

[0058] The provision of flow restrictor 107 ensures that the insulating gas from the air source, after being injected through air inlet passage 105, does not directly enter plenum chamber 104. Instead, it is decelerated by multiple apertures 71 uniformly arranged within flow restrictor 107 before evenly entering the plenum chamber. This ensures that the entire plenum chamber 104 is slowly and evenly filled with insulating gas during the inflation process, allowing the insulating gas to be evenly distributed throughout the plenum chamber 104. This ensures more uniform thermal insulation performance across the entire vehicle sunroof assembly 100, effectively preventing localized insulation performance from failing to meet performance requirements.

[0059] In some embodiments, the pores 71 within the flow restrictor 107 have a diameter ranging from 1 mm to 3 mm, for example, 1 mm, 1.5 mm, 2.0 mm, 2.5 mm, or 3.0 mm. The porosity is set to a value ranging from 10% to 30%, for example, 10%, 15%, 20%, 25%, or 30%. Here, the porosity may refer to the ratio of the volume occupied by the plurality of pores 71 to the total volume of the flow restrictor 107.

[0060] In some embodiments, referring to Figures 3 and 5 , one-way valves 108 are connected to both the inlet channel 105 and the exhaust channel 106. The one-way valves 108 ensure one-way flow of the insulating gas during injection, preventing gas backflow that would affect the efficiency of the insulating gas injection.

[0061] In some embodiments, the air inlet channel 105 is arranged at the front of the partition 13, and the air outlet channel 106 is arranged at the rear of the partition 13; at least one of the left part or the right part of the partition 13 is a porous structure.

[0062] 2 , the partition 13 includes a front member 31 , a left member 32 , a rear member 33 and a right member 34 that form a frame. Two air intake passages 105 are arranged on the front member 31 , and two air exhaust passages 106 are arranged on the rear member 33 .

[0063] For example, the thickness of the front member 31 , the left member 32 , the rear member 33 and the right member 34 is any value between 10 mm and 20 mm, for example, 10 mm, 12 mm, 14 mm, 18 mm or 20 mm.

[0064] The width of the upper surface is any value between 15 mm and 20 mm, for example, the width of the upper surface is 15 mm, 16 mm, 17 mm, 19 mm, or 20 mm.

[0065] The length of the front member 31 and the rear member 33 is any value between 750 mm and 800 mm. For example, the length of the front member 31 and the rear member 33 is 750 mm, 760 mm, 770 mm, 790 mm, or 800 mm.

[0066] Both the left component 32 and the right component 34 include a straight segment and a bent segment connected to the front end of the straight segment. The length of the straight segment is any value between 950mm and 1000mm, for example, the length of the straight segment is 950mm, 960mm, 970mm, 990mm or 1000mm.

[0067] The arc length of the bending section is any value between 200 mm and 240 mm. For example, the arc length of the bending section is 200 mm, 210 mm, 220 mm, 230 mm or 240 mm.

[0068] In some embodiments, the front member 31, left member 32, rear member 33, and right member 34 are separate components, which are easier to manufacture and require less equipment than a one-piece structure. Furthermore, because the front member 31, left member 32, rear member 33, and right member 34 are connected end to end to form a frame structure, they effectively separate the inner side of the skylight glass 11 from the outer side of the light-transmitting member 12 to form the plenum chamber 104. Furthermore, they facilitate the arrangement of a sealing structure to ensure the sealing performance of the plenum chamber 104.

[0069] The left component 32 and the right component 34 both have porous structures. On the one hand, while ensuring structural strength, the overall weight of the isolation component 13 is reduced, meeting the lightweight requirements of the vehicle body; on the other hand, the porous structure can play a sound-absorbing role, improving the noise, vibration and harshness (NVH) performance in the passenger compartment, and preventing external noise from being transmitted from the isolation component 13 to the vehicle interior.

[0070] For example, the porosity of the porous structure inside the left and right members 32 and 34 can be any value between 10% and 20%. For example, the porosity of the porous structure inside the left and right members 32 and 34 can be 10%, 12%, 15%, 18%, or 20%. This does not affect the structural performance of the spacer 13 itself, and can effectively reduce weight and provide sound insulation.

[0071] In some embodiments, the light-transmitting element 12 is transparent glass or an organic light-transmitting material, and the material is polycarbonate (PC), polymethyl methacrylate (PMMA), polystyrene (PS), polyethylene (PE), polyvinyl chloride (PVC), or polypropylene (PP).

[0072] In some embodiments, by reasonably setting the material of the light-transmitting component 12, the lighting performance of the vehicle skylight assembly 100 is avoided from being affected. In addition, since the light-transmitting component 12 is arranged on the inner side of the skylight glass 11, that is, the usage scenario of the light-transmitting component 12 is the passenger compartment in the vehicle, compared with the skylight glass 11 that is in direct contact with the external environment, the application environment of the light-transmitting component 12 is relatively good. Therefore, the performance requirements of the light-transmitting component 12, such as high salt resistance, high temperature resistance, high humidity resistance, impact resistance, and scratch resistance, are generally lower than those of the skylight glass 11. Accordingly, the manufacturing cost of the light-transmitting component 12 will also be reduced.

[0073] In some embodiments, as shown in Figures 3 and 6 , at least one of the inner or outer surfaces of the light-transmitting element 12 is coated with a first diffuse reflective film layer 14. The provision of the first diffuse reflective film layer 14 effectively resolves the issues of in-vehicle reflection and ghosting, ensuring the basic perspective function of the vehicle skylight assembly 100.

[0074] Typically, high-gloss decorative parts inside a car, such as chrome trim rings and display screens, have smooth, high-gloss surfaces and excellent reflectivity. When light reflected from the interior reaches the interior light-transmitting member 12, the smooth surface of the light-transmitting member 12 provides a first reflection image.

[0075] In addition, after the light is refracted into the cavity layer (i.e., the air-filled chamber 104) through the light-transmitting member 12, the propagation direction of the light changes twice because the refractive index of the filler in the cavity layer is different from that of the light-transmitting member 12. After the light reaches the second layer of glass interface of the skylight glass 11, a second reflection image appears due to the good reflectivity of the smooth glass interface.

[0076] In addition, after the light passes through the second layer of glass of the skylight glass 11 and refracts into the interlayer, the refractive index of the interlayer is different from that of the second layer of glass, further changing the propagation direction of the light. After the light reaches the outermost layer of glass, due to the good reflectivity of the smooth glass interface, a third reflection image appears. If the outermost layer of glass is colored glass, the light absorption of the colored glass can reduce the clarity of the third image.

[0077] In summary, multiple reflections and refractions result in different imaging positions for the three images, resulting in visual ghosting. In some embodiments of the present disclosure, the vehicle skylight assembly 100 includes a first diffuse reflection film layer 14 on at least one of the inner or outer surfaces of the light-transmitting element 12. Because the microscopic surface of the first diffuse reflection film layer 14 is uneven, upon incident light reaching the interface, these uneven surfaces reflect the light in all directions, resulting in inconsistent normals at each point, causing the reflected light to appear disordered and irregular. This effectively solves the issues of in-vehicle reflection and ghosting, ensuring the basic perspective function of the vehicle skylight assembly 100.

[0078] In some embodiments, both the inner and outer surfaces of the light-transmitting member 12 are coated with a first diffuse reflection film layer 14, the first diffuse reflection film layer 14 is a silicon dioxide nanoparticle layer, and the thickness of the first diffuse reflection film layer 14 is any value between 10 μm and 20 μm. For example, the thickness of the first diffuse reflection film layer 14 is 10 μm, 12 μm, 15 μm, 18 μm, or 20 μm.

[0079] In some embodiments, the skylight glass 11 is insulating glass, laminated glass, coated glass or tempered glass.

[0080] In some embodiments, by reasonably setting the category of the skylight glass, the external skylight glass 11 can meet the basic performance requirements, that is, the visible light transmittance is >3%, the total sunlight transmittance is <16%, and the wear resistance, heat resistance, radiation resistance, impact resistance, penetration resistance, and edge stress (tensile stress <12Mpa, compressive stress >20Mpa) can all meet the performance requirements.

[0081] In some embodiments, the skylight glass 11 can constitute a first heat-insulating layer, which, when used in conjunction with the added light-transmitting member 12 and the heat-insulating gas in the air-filled chamber 104 , serves to isolate external heat.

[0082] In some embodiments, as shown in Figure 3 , the inner surface of the skylight glass 11 is coated with a second diffuse reflective film 15 . This second diffuse reflective film 15 is a layer of silica nanoparticles, and its thickness is set to any value between 10 μm and 20 μm. For example, the thickness of the second diffuse reflective film 15 is 10 μm, 12 μm, 15 μm, 17 μm, or 20 μm. The second diffuse reflective film 15, in conjunction with the first diffuse reflective film 14 on the light-transmitting element 12, effectively resolves the issues of in-vehicle reflection and ghosting, ensuring the basic perspective function of the vehicle skylight assembly 100.

[0083] It should be noted that the material of at least one of the first diffuse reflection film layer 14 or the second diffuse reflection film layer 15 is a nanoparticle layer such as silicon dioxide, titanium dioxide, zinc oxide, aluminum oxide, zinc aluminum oxide, magnesium fluoride, lithium fluoride, silicon nitride, aluminum nitride, titanium nitride, or silicon carbide.

[0084] In some embodiments, referring to FIG. 3 , the spacer 13 serves as an insert, the spacer 13 and the light-transmitting member 12 are integrally injection-molded, and the spacer 13 is connected to the inner surface of the skylight glass 11 . For example, the spacer 13 and the inner surface of the skylight glass 11 can be glued and fixed by a structural adhesive 130 .

[0085] Because the spacer 13 is an insert and is integrally injection-molded with the light-transmitting member 12, the spacer 13 fits tightly against the light-transmitting member 12, ensuring a tight seal. This eliminates the need for a separate sealing structure between the spacer 13 and the light-transmitting member 12, reducing the number of manufacturing steps. Because the spacer 13 and the skylight glass 11 are bonded together using structural adhesive 130, the connection is stable and reliable. The adhesive also ensures a seamless seal between the spacer 13 and the skylight glass 11.

[0086] Some embodiments of the present disclosure also provide a method for manufacturing the above-mentioned vehicle skylight assembly 100, which includes: connecting (such as fixing) the isolation member 13 to the outer surface of the light-transmitting member 12; connecting (such as fixing) the isolation member 13 with the light-transmitting member 12 to the inner surface of the skylight glass 11, forming an inflatable chamber 104 between the inner side of the skylight glass 11 and the outer side of the light-transmitting member 12; and injecting insulating gas into the inflatable chamber 104.

[0087] In some embodiments, injecting insulating gas into the inflation chamber 104 includes: connecting the gas source to the air inlet channel 105 on the isolation member 13, connecting the gas content detection component 140 to an exhaust channel 106 on the isolation member 13, and connecting the remaining exhaust channels 106 to the external air; turning on the gas source, and starting to inject insulating gas into the inflation chamber 104, and the air in the inflation chamber 104 is squeezed and discharged through the exhaust channel 106 on the isolation member 13; when the gas content detection component 140 detects that the insulating gas reaches a preset threshold, turning off the gas source, disconnecting the connection between the gas source and the air inlet channel 105 on the isolation member 13, and disconnecting the connection between the gas content detection component 140 and the exhaust channel 106 on the isolation member 13, and using the blocking cover 110 to seal the air inlet channel 105 and the exhaust channel 106.

[0088] For example, referring to Figure 5 , the gas content detection assembly 140 is an airbag. When insulating gas is injected, the air in the inflation chamber 104 is first exhausted through the exhaust channel 106, which is not connected to the gas content detection assembly 140 (i.e., the airbag). Then, the closing insert 150 is pressed downward to preliminarily block the exhaust channel 106. The insulating gas is then continuously injected, and the expansion of the airbag is observed. After the airbag has inflated to 90%, the injection of insulating gas is stopped, the gas source is turned off, and the connection between the gas source and the air inlet channel 105 on the isolation member 13 and the connection between the gas content detection assembly 140 and the exhaust channel 106 on the isolation member 13 is disconnected. The air inlet channel 105 and the exhaust channel 106 are then blocked with the blocking cover 110.

[0089] Here, the airbag has a maximum expanded volume (or capacity). When the airbag is 90% expanded, it means that its actual volume has reached 90% of its maximum capacity. For example, if the airbag's maximum capacity is 100 liters, then a 90% expansion state means that the airbag's volume at that time is 90 liters. Alternatively, if the airbag has a maximum design pressure, a 90% expansion state can mean that the airbag's internal pressure has reached 90% of the maximum design pressure.

[0090] In some embodiments, a method for manufacturing the vehicle skylight assembly 100 includes:

[0091] Double-layer laminated composite coated glass made by existing mature technology is selected as the skylight glass 11. A second diffuse reflection film layer 15 is coated on the inner surface of the skylight glass 11. The material of the second diffuse reflection film layer 15 is silicon dioxide nanoparticles, and the thickness of the second diffuse reflection film layer 15 is 10μm.

[0092] The spacer 13 is prepared by sequentially manufacturing the front member 31, left member 32, rear member 33, and right member 34 using mold forming. The front member 31, left member 32, rear member 33, and right member 34 are designed to conform to the perimeter contour of the light-transmitting member 12. Specifically, the frame formed by the front member 31, left member 32, rear member 33, and right member 34 serves as the mounting frame for the light-transmitting member 12. The dimensional parameters of the front member 31, left member 32, rear member 33, and right member 34 include a thickness of 15 mm and a top surface width of 20 mm. The front member 31 and rear member 33 are 800 mm long, and the left member 32 and right member 34 each include a straight segment and a curved segment connected to the front end of the straight segment. For example, the straight segment is 1000 mm long, and the curved segment has an arc length of 200 mm.

[0093] Prepare the light-transmitting part 12, place the front component 31, the left component 32, the rear component 33 and the right component 34 together with the prefabricated material of the light-transmitting part 12 into an injection mold, so that the isolation part 13 is injection-molded as an insert together with the light-transmitting part 12, and the light-transmitting part 12 is formed into a curvature surface corresponding to the skylight glass 1 through the injection mold.

[0094] Place the skylight glass 11 on the bonding fixture and position it by the edge of the skylight glass 11. Subsequently, apply structural adhesive 130 to the upper surface of the spacer 13, and set the width of the structural adhesive 130 to 6mm. Using a mechanical transfer, place the light-transmitting component 12 with the spacer 13 on the bonding fixture to complete the bonding operation of the light-transmitting component 12 and the spacer 13 to the skylight glass 11. Remove and let it stand. After the structural adhesive 130 has dried, transfer the glass assembly including the skylight glass 11, the light-transmitting component 12, and the spacer 13 to the nitrogen injection chamber.

[0095] Both air inlet passages 105 of the front member 31 of the spacer 13 are connected to the nitrogen injection equipment. One exhaust passage of the rear member 33 of the spacer 13 is connected to the external environment, and the other exhaust passage 106 is provided with a gas content detection assembly 140 (e.g., a pressure gauge). For example, the other exhaust passage 106 is provided with a connecting pipe of the pressure gauge.

[0096] The nitrogen injection device is turned on to continuously inject nitrogen into the plenum chamber 104. The air in the plenum chamber 104 is first expelled through the exhaust channel 106 not connected to the gas content detection assembly 140 (i.e., the pressure gauge). The closing insert 150 is then pressed downward to preliminarily block the exhaust channel 106. The insulating gas is then continuously injected. As the insulating gas content increases to over 90%, the pressure in the cavity layer reaches equilibrium with the ambient pressure. The pressure gauge on the detection assembly 140 displays a value between 0.92 and 1.01 MPa. The insulating gas injection is then stopped, the gas source is turned off, and the connection between the gas source and the inlet channel 105 on the isolation member 13, as well as the connection between the gas content detection assembly 140 and the exhaust channel 106 on the isolation member 13, is disconnected. The inlet channel 105 and the exhaust channel 106 are then blocked with the plug 110. In order to improve the sealing performance, a sealant 120 is applied to the interfaces between the blocking cover 110 and the air intake channel 105 and the exhaust channel 106 to complete the preparation of the vehicle skylight assembly 100.

[0097] Here, the increase of the insulating gas content to more than 90% may mean that the insulating gas content accounts for more than 90% of the total gas content in the gas-filled chamber 104 .

[0098] A skylight glass from related art was used as a comparative example. This skylight glass was double-layer laminated composite coated glass produced using a mature process. Using a vehicle skylight assembly 100 produced according to some embodiments of the present disclosure as an example, computer-aided engineering (CAE) simulation tests were performed to obtain temperature distribution results on the glass surface. The analysis results are shown in Figures 7A and 7B and Table 1.

[0099] Table 1 Summary of CAE simulation test results of the embodiments and comparative examples

[0100] The simulation analysis results show that the thermal insulation performance of the embodiment is significantly better than that of the comparative example. The inner surface temperature of the vehicle sunroof assembly 100 of the embodiment obtained through simulation analysis is 9.9°C lower than that of the sunroof assembly in the comparative example, and the head temperature is reduced by 3.4°C. Here, the head temperature can refer to the temperature at the top of the sunroof glass, or the temperature corresponding to the head position of the passenger or driver.

[0101] Subsequently, a vehicle environmental chamber real vehicle comparison test was conducted. The vehicle air conditioner was turned on, and the cooling parameters of the embodiment and the comparative example were adjusted to the same. The head temperature was recorded after idling for 10 minutes and 30 minutes. The comparison results are shown in Table 2.

[0102] Table 2 Head temperature records after the air conditioner is turned on and idling for 10 minutes and 30 minutes

[0103] It can be seen from the measured temperature that the thermal insulation performance of the vehicle skylight assembly 100 in some embodiments of the present disclosure is significantly better than that of the comparative example.

[0104] In the foregoing, an example is used in which an air-filled chamber 104 is formed between the inner side of the sunroof glass 11 and the outer side of the light-transmitting member 12 in the vehicle sunroof assembly 100, and the air-filled chamber 104 is filled with heat-insulating gas to reduce "secondary heat radiation" from the inner surface of the sunroof glass 1 to the interior of the vehicle, thereby weakening the further transfer of heat into the vehicle. Of course, in some embodiments, other gases can be introduced between the inner side of the sunroof glass 11 and the outer side of the light-transmitting member 12 to carry away heat through the flow of the other gases, thereby weakening the further transfer of heat into the vehicle.

[0105] In some embodiments, referring to Figures 8 to 11, the vehicle skylight assembly 100 includes a skylight 1, which includes a skylight glass 11, a light-transmitting member 12 and an isolation member 13. The skylight glass 11 is connected (such as fixed) to the vehicle body 5, and the light-transmitting member 12 is connected (such as fixed) to the inner side of the skylight glass 11 through the isolation member 13.

[0106] 18 , a ventilation cavity 16 is formed between the inner side of the skylight glass 11 and the outer side of the light-transmitting member 12 . The isolation member 13 is provided with at least one air inlet 131 and at least one air outlet 132 communicating with the ventilation cavity 16 .

[0107] The vehicle sunroof assembly 100 in some embodiments of the present disclosure, on the one hand, has a light-transmitting member 12 added to the inner side of the sunroof glass 11, and a ventilation cavity 16 is formed between the inner side of the sunroof glass 11 and the outer side of the light-transmitting member 12. A preset gas is introduced into the ventilation cavity 16 through the air supply element 4 (as shown in FIG12 ). The preset gas can absorb heat and be discharged through the air outlet 132 to form convection to quickly take away the heat, thereby achieving a good heat dissipation effect, effectively reducing the inner surface temperature of the sunroof assembly close to the passenger side, reducing the "secondary heat radiation" from the inner surface of the sunroof glass 11 to the interior of the vehicle, weakening the further transfer of heat into the vehicle, and fundamentally solving the problems of "burning the head" and "burning the hands" of existing sunroof glasses.

[0108] Furthermore, because the light-transmitting element 12 is secured to the inside of the sunroof glass 11 via the spacer 13, the connection is stable and reliable, eliminating the need for structural modifications to the sunroof glass used in related art, thus reducing development costs. Furthermore, by adjusting the height of the spacer, the thickness of the ventilation cavity 16 between the inside of the sunroof glass 11 and the outside of the light-transmitting element 12 can be adjusted, making manufacturing quick and easy, and better meeting the heat dissipation requirements of different vehicle models.

[0109] Please refer to Figures 8 to 10. The vehicle body 5 includes a vehicle body outer frame 51, a vehicle body inner frame 52 and a vehicle interior decoration 53. The skylight glass 11 is fixed to the vehicle body 5 by gluing, clamping or other connection methods.

[0110] In some embodiments, referring to FIG12 , the vehicle canopy assembly 100 further includes an air inlet duct 2, an air outlet duct 3, and an air supply element 4. The first end of the air inlet duct 2 is connected to the air inlet 131, and the second end of the air inlet duct 2 is connected to the air supply element 4. The first end of the air outlet duct 3 is connected to the air outlet 132, and the second end of the air outlet duct 3 is in communication with a gas recovery element or the outside air.

[0111] The preset gas generated by the air supply element 4 is introduced into the ventilation cavity 16 through the air inlet pipe 2, and the gas in the ventilation cavity 16 is discharged to the gas recovery element or the outside air through the air outlet pipe 3, taking away the heat from the inner surface of the skylight glass 11, reducing the "secondary heat radiation" from the inner surface of the skylight glass 11 to the interior of the car, and weakening the further transfer of heat into the car.

[0112] In some embodiments, referring to FIG12 , the air inlet duct 2 is provided with (e.g., fixed) a first axial flow fan 6 for increasing the air intake volume, and the air outlet duct 3 is provided with (e.g., fixed) a second axial flow fan 7 for increasing the air exhaust volume.

[0113] For example, a first axial flow fan 6 is fixed to the end of the air inlet duct 2 connected to the air inlet 131, and a second axial flow fan 7 is fixed to the end of the air outlet duct 3 connected to the air outlet 132. The first axial flow fan 6 regulates the wind speed within the air inlet duct 2, ensuring sufficient air intake into the ventilation cavity 16. The second axial flow fan 7 regulates the wind speed within the air outlet duct 3, ensuring sufficient suction speed at the air outlet 132 and ensuring that the air in the ventilation cavity 16 can be discharged in a timely manner.

[0114] In some embodiments, the first axial flow fan 6 and the second axial flow fan 7 are both commercially available miniature ultra-quiet fans. Due to limited layout space, the external dimensions are limited to 30mm×50mm, the power range is 5W~8W, and they are installed on the vehicle body frame (such as, at least one of the vehicle body outer frame 51 or the vehicle body inner frame 52) by clamp fixing.

[0115] In some embodiments, referring to Figures 13 and 14 , the outer wall of the connection between the first axial flow fan 6 and the air inlet duct 2 is wrapped with a first thermal insulation member 8. The outer wall of the connection between the second axial flow fan 7 and the air outlet duct 3 is wrapped with a second thermal insulation member. For example, both the first thermal insulation member 8 and the second thermal insulation member are thermal insulation cotton.

[0116] The setting of the first thermal insulation member 8 and the second thermal insulation member, on the one hand, plays a sealing role to prevent the gas in the air inlet pipe 2 or the air outlet pipe 3 from leaking, and on the other hand, plays a heat insulation role to prevent the external hot environment from affecting the gas in the air inlet pipe 2 or the air outlet pipe 3 and reducing the heat dissipation effect.

[0117] It should be noted that the air inlet pipe 2 and the air outlet pipe 3 are covered with thermal insulation components (such as the first thermal insulation component 8 and the second thermal insulation component) near the heat source, which can prevent the heat emitted by the heat source from causing the gas temperature in the air inlet pipe 2 or the air outlet pipe 3 to rise, affecting the cooling effect of the ventilation cavity 16.

[0118] In some embodiments, referring to FIG. 18 , at least one first air guide blade 9 is disposed (e.g., fixed) at the air inlet 131 of the partition member 13, and at least one second air guide blade 10 is disposed (e.g., fixed) at the air outlet 132 of the partition member 13. The arrangement of the first air guide blades 9 directs incoming air toward the light-transmitting member 12 near the inside of the ventilation cavity 16, thereby removing heat from the interior of the canopy assembly. The arrangement of the second air guide blades 10 directs air near the inside of the ventilation cavity 16 toward the exhaust port, thereby improving the efficiency of gas discharge within the ventilation cavity 16.

[0119] For example, the first air guide blade 9 and the second air guide blade 10 are inclined downward by 3° to 5°. The first air guide blade 9 and the second air guide blade 10 are components with a thick root and a thin end, and the thickness range is 1mm to 2.5mm. For example, the root thickness of the first air guide blade 9 and the second air guide blade 10 is 2.5mm, and the end thickness is 1mm.

[0120] In some embodiments, air supply element 4 is a pump. The first end of air outlet pipe 3 is connected to air outlet 132, and the second end of air outlet pipe 3 is connected to a gas recovery element. This connection between the pump and the gas recovery element enables gas recycling. By rationally adjusting the gas composition within ventilation cavity 16 according to actual heat dissipation requirements, a targeted solution can be provided.

[0121] In some embodiments, the air supply element 4 is a vehicle air conditioning system, which can fully utilize the vehicle's existing mature air conditioning system without the need to arrange additional independent structural elements, thereby reducing the manufacturing difficulty and cost of the vehicle skylight assembly 100.

[0122] In some embodiments, as shown in FIG12 , the spacer 13 is a rectangular frame structure. Because the spacer 13 is configured as a rectangular frame structure, it effectively separates the skylight glass 11 and the light-transmitting member 12 , and can cooperate with the skylight glass 11 and the light-transmitting member 12 to form a ventilation cavity 16 , ensuring the sealing performance of the ventilation cavity 16 .

[0123] Please refer to Figures 12, 15 and 18. Two air inlets 131 are arranged on the front side of the isolation member 13. The air inlet duct 2 connected to the front air inlet 131 passes through the gap in the A-pillar and is connected to the defrost duct 41 of the vehicle air-conditioning system. A support ear is provided on the defrost duct 41 for connecting to the end of the air inlet duct 2.

[0124] Referring to Figures 12, 16, and 18, an air inlet 131 is located on the left and right front portions of the partition 13. Air inlet ducts 2 connected to these left and right air inlets 131 pass through the gap within the B-pillar and connect to the foot-blowing duct 43 of the vehicle's air conditioning system. For example, the end of the air inlet duct 2, away from the ventilation cavity 16, passes through the door sill trim 55 and then connects to the outlet end of the foot-blowing duct 43, which passes through the front seat cross member 56.

[0125] Please refer to Figures 12, 17 and 18. Four air outlets 132 are arranged on the rear side of the isolation member 13. The air outlet duct 3 connected to the rear air outlet 132 passes through the gap in the C-pillar and is connected to the vehicle body exhaust port 54.

[0126] By using the gap between the vehicle's A-pillar and B-pillar as the accommodation space for the air inlet duct 2, the ventilation cavity 16 is effectively connected to the foot-blowing air duct 43, the defrost air duct 41 or the face-blowing air duct 42 of the vehicle's air-conditioning system through the air inlet duct 2, and the air-conditioning outlet air can be effectively introduced into the ventilation cavity 16, thereby reducing the temperature of the vehicle skylight assembly 100.

[0127] Similarly, referring to Figure 17 , the gap within the vehicle's C-pillar serves as a space for the air outlet duct 3, allowing the high-heat air within the ventilation cavity 16 to be expelled by the incoming air, thus dissipating heat. Furthermore, the coordinated operation of the air inlet duct 2 and the air outlet duct 3 creates a directional air flow within the ventilation cavity 16, effectively dissipating heat and fundamentally resolving the issues of head and hand burns associated with existing skylight glass.

[0128] In some embodiments, the skylight glass 11 can constitute a first heat-insulating layer, and cooperate with the added light-transmitting member 12 and the flowing air in the ventilation cavity 16 to isolate the external heat.

[0129] For example, the skylight glass 11 is a laminated glass, as shown in FIG19 . The laminated glass includes an outer glass 111 , a high reflective film 112 , an interlayer 113 and an inner glass 114 from the outside to the inside.

[0130] For example, the high reflective film 112 is a silver nanofilm, which is coated on the inner surface of the outer glass 111 and has a thickness of 140 μm to 200 μm.

[0131] The outer glass 111 is made of green glass or gray glass, and the inner glass 114 is made of clear glass. The thickness of the outer glass 111 and the inner glass 114 is between 1.5 mm and 2.5 mm. For example, the thickness of the outer glass 111 and the inner glass 114 is 1.5 mm, 1.8 mm, 2.0 mm, 2.2 mm, or 2.5 mm.

[0132] In some embodiments, the surface of the skylight glass 11 close to the ventilation cavity 16 is coated with a first diffuse reflection film layer 14 ; the surface of the light-transmitting element 12 close to the ventilation cavity 16 is coated with a second diffuse reflection film layer 15 .

[0133] For example, the thickness of the first diffuse reflection film layer 14 and the second diffuse reflection film layer 15 are independently set to any value between 10 μm and 20 μm. For example, the thickness of the first diffuse reflection film layer 14 and the second diffuse reflection film layer 15 is 10 μm, 12 μm, 15 μm, 18 μm or 20 μm.

[0134] For example, the materials of the first diffuse reflection film layer 14 and the second diffuse reflection film layer 15 are independently selected from nanoparticle layers such as silicon dioxide, titanium dioxide, zinc oxide, aluminum oxide, zinc aluminum oxide, magnesium fluoride, lithium fluoride, silicon nitride, aluminum nitride, titanium nitride or silicon carbide.

[0135] In some embodiments, the provision of the first diffuse reflective film layer 14 and the second diffuse reflective film layer 15 effectively resolves the issues of interior reflection and ghosting, ensuring the basic perspective function of the vehicle skylight assembly 1. Typically, high-gloss interior decorative parts, such as chrome trims and display screens, possess excellent reflectivity due to their smooth, high-gloss surfaces. When light reflected from within the vehicle reaches the interior light-transmitting element 12, it forms a primary reflection image due to the excellent reflectivity of the smooth surface of the light-transmitting element 12.

[0136] In addition, after the light is refracted into the ventilation cavity 16 through the light-transmitting member 12, since the ventilation cavity 16 contains gas, the refractive index of the gas is different from that of the light-transmitting member 12, and the propagation direction of the light changes twice. After the light reaches the second glass interface of the skylight glass 11, a second reflection imaging occurs due to the good reflectivity of the smooth glass interface.

[0137] Furthermore, after light passes through the second layer of glass, i.e., the inner layer 114, of the skylight glass 11 and refracts into the interlayer 113, the interlayer 113 further changes its direction of propagation due to its different refractive index from the inner layer 114. When the light reaches the outermost layer of glass, i.e., the outer layer 111, a third reflection image is formed due to the excellent reflectivity of the smooth glass interface. If the outermost layer of glass is colored glass, the light absorption of the colored glass may reduce the clarity of the third image.

[0138] In summary, multiple reflections and refractions result in different imaging positions three times, thus presenting visual ghosting. In some embodiments of the present disclosure, the vehicle skylight assembly 100 is coated with a first diffuse reflection film layer 14 on the surface of the skylight glass 11 close to the ventilation cavity 17, and a second diffuse reflection film layer 15 on the surface of the light-transmitting component 12 close to the ventilation cavity 16. Since the microscopic surfaces of the first diffuse reflection film layer 14 and the second diffuse reflection film layer 15 are uneven, after the incident light reaches the interface, these uneven surfaces will reflect the light in all directions, and the normals of each point are inconsistent, causing the reflected light to appear disordered and irregular, thereby effectively solving the problems of in-vehicle mapping and ghosting, and ensuring the basic perspective function of the vehicle skylight assembly 100.

[0139] In addition, since the first diffuse reflection film layer 14 and the second diffuse reflection film layer 15 are nano-particle film layers, the nano-particles form a tiny uneven film structure on the surface of the skylight glass 11 and the light-transmitting component 12 on one side close to the ventilation cavity 16, making it difficult for humid air to deposit or adhere to the corresponding surface to form water droplets, effectively preventing cold air from fogging after entering the ventilation cavity 16 and affecting the permeability of the vehicle skylight assembly 100, that is, the first diffuse reflection film layer 14 and the second diffuse reflection film layer 15 can also play an anti-fogging role.

[0140] In some embodiments, as shown in FIG20 , the isolation member 13 is provided with a cleaning liquid inlet 133 and a cleaning liquid outlet 134 that communicate with the ventilation cavity 16. The provision of the cleaning liquid inlet 133 and the cleaning liquid outlet 134 facilitates the injection and discharge of cleaning liquid, allowing for regular cleaning of the ventilation cavity 16 of the canopy assembly to ensure the permeability of the vehicle canopy assembly 100. Furthermore, this facilitates operation and reduces maintenance costs for the vehicle canopy assembly 100.

[0141] Some embodiments of the present disclosure further provide a method for manufacturing a vehicle skylight assembly 100, the method comprising:

[0142] Double-layer laminated composite coated glass produced by an existing mature process is selected as the skylight glass 11. A first diffuse reflection film layer 14 is coated on the inner surface of the skylight glass 11. The material of the first diffuse reflection film layer 14 is silicon dioxide nanoparticles and the thickness is 10 μm.

[0143] Prepare the spacer 13 using a mold. The spacer 13 is designed to conform to the perimeter contour of the light-transmitting element 12. Specifically, the rectangular frame of the spacer 13 serves as a mounting frame for the light-transmitting element 12. The dimensional parameters of the spacer 13 include a thickness of 15 mm, a top surface width of 20 mm, and a front and rear member length of 800 mm. Both the left and right members include a straight segment and a curved segment connected to the front end of the straight segment. For example, the straight segment is 1000 mm long, and the curved segment has an arc length of 200 mm.

[0144] 20 and 21 , two air inlets 131 and a cleaning liquid injection port 133 are provided on the front side of the isolation member 13 , an air inlet 131 is provided on the left front portion and the right front portion, and four air outlets 132 and a cleaning liquid discharge port 134 are provided on the rear side.

[0145] Prepare the light-transmitting part 12, place the isolating part 13 and the prefabricated material of the light-transmitting part 12 into an injection mold together, so that the isolating part 13 is injection-molded as an insert together with the light-transmitting part 12, and the light-transmitting part 12 is molded into a curvature surface corresponding to the skylight glass 11 through the injection mold.

[0146] Place the canopy glass 11 on the bonding fixture and position it by its edge. Then, apply structural adhesive to the upper surface of the spacers 13, with a width of 6 mm. Using a mechanical hand, place the light-transmitting component 12 with the spacers 13 onto the bonding fixture, completing the bonding operation with the canopy glass 11. After removing and allowing the structural adhesive to dry, the canopy 1, including the canopy glass 11, light-transmitting component 12, and spacers 13, is transferred to the final assembly process.

[0147] The cleaning liquid injection port 133 and the cleaning liquid discharge port 134 are sealed with a plugging cover, and the plugging cover can be removed for subsequent cleaning and maintenance.

[0148] Please refer to Figures 12, 15 to 17. The gap between the A-pillar and the B-pillar of the vehicle is used as the accommodation space for the air inlet duct 2, so that the defrost air duct 41 of the vehicle air-conditioning system is connected to the front air inlet 131 of the isolation member 13 through the air inlet duct 2 accommodated in the A-pillar of the vehicle. The foot-blowing air duct 43 of the vehicle air-conditioning system is connected to the left and right air inlets 131 of the isolation member 13 through the air inlet duct 2 accommodated in the B-pillar of the vehicle. The vehicle body exhaust port 54 is connected to the rear air outlet 132 of the isolation member 13 through the air outlet duct 3 accommodated in the C-pillar of the vehicle, thereby realizing the connection between the ventilation cavity 16 and the vehicle air-conditioning system and the vehicle body exhaust port 54.

[0149] A common sunroof glass currently on the market was used as a comparative example. This sunroof glass is double-layer laminated composite coated glass manufactured using a mature process. A vehicle sunroof assembly 100 manufactured using the manufacturing method of the vehicle sunroof assembly 100 in some embodiments of the present disclosure was used as an example. CAE simulation tests were performed to obtain the glass surface temperature distribution results. The analysis results are shown in Figures 24A and 24B and Table 3.

[0150] Table 3 Summary of CAE simulation test results of the embodiments and comparative examples

[0151] From the simulation analysis results, it can be seen that the thermal insulation performance of the embodiments is significantly better than that of the comparison examples. The inner surface temperature of the skylight assembly of some embodiments of the present disclosure obtained by simulation analysis is more than 10°C lower than the inner surface temperature of the skylight assembly of the comparison example, and the head temperature is reduced by 8.8°C.

[0152] Subsequently, a vehicle environmental chamber real vehicle comparison test was conducted. The vehicle air conditioner was turned on, and the cooling parameters of the embodiment and the comparative example were adjusted to the same. The head temperature was recorded after idling for 10 minutes and 30 minutes. The structure is shown in Table 4.

[0153] Table 4 Head temperature record after air conditioning is turned on and idling for 10 minutes and 30 minutes

[0154] It can be seen from the measured temperature that the thermal insulation performance of the embodiment is significantly better than that of the comparative example.

[0155] The present disclosure also provides a control system for a vehicle skylight assembly. Referring to FIG. 22 , the control system includes a control unit 20 , an air supply element 4 connected to an output of the control unit 20 , and an operation instruction unit 30 and a sensor unit 40 connected to an input of the control unit.

[0156] The operation instruction unit 30 generates an operation instruction in response to a user operation, such as temperature setting, air volume setting, mode setting, and air conditioning setting.

[0157] The sensor unit 40 includes an outside temperature sensor, an inside temperature sensor, and a sunlight intensity sensor. The outside temperature sensor is used to collect and obtain the outside ambient temperature, the inside temperature sensor is used to collect and obtain the inside ambient temperature, and the sunlight intensity sensor is used to collect and obtain the outside sunlight intensity.

[0158] The control unit 20 receives the operation instruction of the operation instruction unit 30 and the sensor signal of the sensor unit 40, obtains the output of the air supply element 4 through comprehensive calculation and analysis, and issues a working instruction to the air supply element 4 to control the operation of the air supply element 4.

[0159] In some embodiments, the control unit 20 is a vehicle integrated controller, and the air supply element 4 is a vehicle air conditioning system.

[0160] Some embodiments of the present disclosure further provide a method for controlling a vehicle skylight assembly. Referring to FIG. 23 , the method includes the following steps:
