The dimming layer and the light-emitting layer are disposed between the first structural layer and the second structural layer, and the edges of the dimming layer and the light-emitting layer are located inside the edges of the first structural layer and the second structural layer. The first structural layer, the dimming film, the light-emitting film and the second structural layer are all light-transmitting structures.

A light-emitting chip layer is disposed within the encapsulation layer, and the second electrode sheet is disposed at the edge between the circuit layer and the second substrate layer.

[0010] Optionally, both the first structural layer and the second structural layer are provided with a light-shielding structure so that the glass assembly forms a light-transmitting area and a light-blocking area. The light-transmitting area is located in the middle of the automotive glass assembly, and the light-blocking area is arranged circumferentially around the outside of the light-transmitting area.

[0025] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Although some embodiments of this utility model are shown in the drawings, it should be understood that this utility model can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this utility model. It should be understood that the drawings and embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0026] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to"; the term "based on" means "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; and the term "optionally" means "optional embodiments". Definitions of other terms will be given in the following description. It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0027] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless explicitly stated otherwise in the context, they should be understood as "one or more". "Several" refers to one or more "one or more".

[0028] Light transmittance usually refers to the proportion of light that passes through in a direction perpendicular to the surface of a material (the normal direction), which is the standard definition in optical measurement and material performance evaluation.

[0029] like Figure 1-5As shown, this embodiment of the present invention provides a glass assembly, including a first structural layer 31, a dimming layer, a light-emitting layer, and a second structural layer 32 stacked together. The dimming layer includes a dimming film 11 for adjusting light transmittance and a first protective ring 12 surrounding the outside of the dimming film 11 in the circumferential direction. A first lead-out line 13 of the dimming film 11 is led out through the first protective ring 12. The light-emitting layer includes a light-emitting film 21 for displaying a preset pattern and a second protective ring 22 surrounding the outside of the light-emitting film 21 in the circumferential direction. A second lead-out line 23 of the light-emitting film 21 is led out through the second protective ring 22. The dimming layer and the light-emitting layer are disposed between the first structural layer 31 and the second structural layer 32, and the edges of the dimming layer and the light-emitting layer are located inside the edges of the first structural layer 31 and the second structural layer 32. The first structural layer 31, the dimming film 11, the light-emitting film 21, and the second structural layer 32 are all light-transmitting structures.

[0030] In this optional embodiment, the glass assembly is composed of four layers stacked together: a first structural layer 31, a dimming layer, a light-emitting layer, and a second structural layer 32. The dimming layer is a transmittance adjustment functional layer. The transmittance of the dimming film 11 can be dynamically adjusted to adapt to different environments. For example, during the day, the transmittance can be reduced to decrease glare, while at night, the transmittance can be increased to enjoy the starry sky. It can also prevent external peeping by lowering the transmittance, meeting different usage needs. Commonly used dimming films include electrochromic films, which precisely control the arrangement of electrochromic molecules or liquid crystals through an electric field to achieve stepless adjustment of transmittance from transparent to frosted. The light-emitting layer is a functional layer for displaying different patterns. By emitting light through light-emitting crystals on the light-emitting film 21, different patterns can be displayed, such as a starry sky pattern, forming a starry sky ceiling effect.

[0031] The edges of the first structural layer 31 and the second structural layer 32 are connected to the vehicle body. The dimming layer and the luminous layer are sandwiched between the first structural layer 31 and the second structural layer 32, so that the dimming layer and the luminous layer are completely covered and protected, preventing the luminous layer from being directly exposed to the external space and from being directly impacted by hard objects such as the occupant's head and luggage. Moreover, the edges of the dimming layer and the light-emitting layer are located inside the edges of the first structural layer 31 and the second structural layer 32, so that the edges of the dimming film 11 and the light-emitting film 21 are both recessed within the edge contour range of the glass assembly. At the same time, the dimming film 11 is circumferentially encapsulated by the first protective ring 12, and the light-emitting film 21 is circumferentially encapsulated by the second protective ring 22. That is, the first structural layer 31, the second structural layer 32, the first protective ring 12 and the second protective ring 22 form a closed stacked structure, which effectively avoids the erosion and damage caused by external environmental factors to the dimming layer and the light-emitting layer, further improving the durability of use, and can also reduce the risk of interlayer displacement of the inner dimming layer and the light-emitting layer caused by vehicle vibration, and prevent fatigue failure of the adhesive layer.

[0032] It should be noted that the first structural layer 31, the dimming layer, the light-emitting layer, and the second structural layer 32 are all stacked along the thickness direction. Generally, the first structural layer 31, the dimming layer, the light-emitting layer, and the second structural layer 32 are all light-transmitting structures with a visible light transmittance greater than 80%. There are two ways to position the dimming layer and the light-emitting layer between the first structural layer 31 and the second structural layer 32: one is to place the dimming layer closer to the first structural layer 31, and the other is to place the dimming layer closer to the second structural layer 32. Since both are light-transmitting layers, the order in which the light passes through them is irrelevant.

[0033] Optionally, such as Figure 2 and Figure 3 As shown, adjacent layers are bonded together by an adhesive layer 4, and the first protective ring 12, the second protective ring 22 and the adhesive layer 4 are made of the same material.

[0034] In this optional embodiment, in the four-layer structure of the first structural layer 31, the dimming layer, the light-emitting layer, and the second structural layer 32, adjacent layers are connected by a common adhesive method. Common materials for the adhesive layer 4 include PVB and PU. PVB stands for Polyvinyl Butyral; PU stands for Polyurethane Adhesive. PU is an abbreviation for Polyurethane.

[0035] In addition, the first protective ring 12, the second protective ring 22 and the adhesive layer 4 are made of the same material. On the one hand, the three have the same physical and chemical properties, especially the same coefficient of thermal expansion. The difference in expansion when heated is small, which reduces the phenomenon of interlayer peeling and maintains a stable enclosure and encapsulation of the dimming film 11 and the light-emitting film 21. On the other hand, the molecular compatibility between the same materials is stronger, which improves the reliability of interlayer bonding. In addition, the first protective ring 12 and the second protective ring 22 can be prepared together with the interlayer adhesive layer 4, which can simplify the preparation process.

[0036] Optionally, such as Figure 2 and Figure 3 As shown, the outer edges of the first protective ring 12, the second protective ring 22, and the adhesive layer 4 are all aligned, the edges of the first structural layer 31 and the second structural layer 32 are aligned, and the edge of the first structural layer 31 is located outside the outer edge of the first protective ring 12 shown.

[0037] In this optional embodiment, the outer edges of the first protective ring 12, the second protective ring 22, and the adhesive layer 4 are all aligned to avoid interlayer misalignment gaps and improve the structural integrity between the first structural layer 31 and the second structural layer 32. The edges of the first structural layer 31 and the second structural layer 32 are aligned, and the edge of the first structural layer 31 is located outside the outer edge of the first protective ring 12, so that the outer circumference between the first structural layer 31 and the second structural layer 32 has a space for a sealing structure, a second lead-out line 23, a first lead-out line 13, and other structures.

[0038] Optionally, such as Figure 1 , Figure 2 and Figure 4 As shown, the dimming film 11 is provided with a first electrode 14. The first electrode 14 protrudes from the bottom edge of the dimming film 11, and the protruding part is embedded in the first protective ring 12. One end of the first lead-out line 13 is connected to the protruding part of the first electrode 14, and the other end is led out through the first protective ring 12.

[0039] In this optional embodiment, the first electrode sheet 14 is disposed at the bottom edge of the dimming film 11 in the thickness direction. The specific arrangement structure is as follows: Figure 2 As shown, a notch is formed at the bottom edge of the dimming diaphragm 11, and a notch is also formed at the corresponding position of the first protective ring 12. The first electrode sheet 14 is divided into two parts along the width direction. One part is embedded in the dimming diaphragm 11 and is electrically connected to the internal structure of the dimming diaphragm 11. The other part protrudes from the dimming diaphragm 11 and is embedded in the notch of the first protective ring 12 and is surrounded and protected by the first protective ring 12. At the same time, this part is connected to the first lead-out line 13. The entire bottom surface of the first electrode sheet 14 is flush with the bottom surface of the dimming diaphragm 11.

[0040] By embedding the first electrode sheet 14, which protrudes from the dimming film 11, into the first protective ring 12, the first electrode sheet 14 is surrounded and protected by the stacked structure and the first protective ring 12, effectively preventing the first electrode sheet 14 from being corroded by the external environment and improving its stability in use.

[0041] It should be noted that the dimming film 11 has two flat surfaces arranged opposite each other along the thickness direction. To avoid confusion, these are referred to as the "top surface" and the "bottom surface," respectively. It should be emphasized that "top surface" and "bottom surface" are only relative terms and do not represent fixed spatial positions. For example, the top surface can refer to the surface of the dimming film 11 facing the first structural layer 31, or it can refer to the surface facing the second structural layer 32. In this embodiment, the bottom of the edge of the dimming film 11 refers to the portion of the edge near the bottom surface.

[0042] Optionally, the dimming film 11 and the first protective ring 12 have the same thickness, so that the thickness of the entire dimming layer is consistent, which facilitates the design and manufacturing of the stacked structure of the entire glass assembly.

[0043] Optionally, the dimming film 11 can achieve zone control, enabling independent and precise adjustment of the transmittance of different areas of the film according to different usage requirements.

[0044] Optionally, such as Figure 6 As shown, the glass assembly also includes a first protective film 15 disposed at the edge of the dimming film 11. The first protective film 15 includes an upper film 151, a middle film 152 and a lower film 153 connected in a Z-shape in sequence. The upper film 151 is attached to the top edge of the dimming film 11, the middle film 152 is attached to the outer side of the edge of the dimming film 11, and the lower film 153 is attached to the top surface of the protruding part of the first electrode sheet 14.

[0045] In this optional embodiment, a Z-shaped first protective film 15 is attached to the top surface of the first electrode sheet 14 that protrudes from the dimming film 11, and to the corresponding area of ​​the dimming film 11. The first protective film 15 is typically a thin PI film, used to protect the connecting lines on the first electrode sheet 14. PI plastic raw material is commonly known as polyimide.

[0046] It should be noted that the bottom and top surfaces of the dimming film 11 refer to the surface that the light first contacts when it enters the vehicle from outside the vehicle, which is the top surface, and the surface that contacts it later, which is the bottom surface.

[0047] Optionally, the bonding width of the first electrode sheet 14 is not less than 4 mm. Bonding refers to the process of establishing an electrical connection between the conductive edge of the dimming film 11 and the middle of the lead-out electrode. Increasing the bonding width helps to improve the connection reliability.

[0048] Optionally, such as Figure 1 , Figure 3 and Figure 5 As shown, the light-emitting film 21 is provided with a second electrode 24. The second electrode 24 protrudes from the edge of the light-emitting film 21 and the protruding part is embedded in the second protective ring 22. One end of the second lead-out line 23 is connected to the protruding part of the second electrode 24, and the other end is led out through the second protective ring 22.

[0049] In this optional embodiment, the second electrode sheet 24 is disposed at the middle position in the thickness direction of the light-emitting film 21. The specific arrangement structure is as follows: Figure 3As shown, a groove is cut at the middle of the edge of the light-emitting film 21 along the thickness direction, and a corresponding groove is cut in the second protective ring 22. The second electrode plate 24 is divided into two parts along the width direction. One part is embedded in the light-emitting film 21 and electrically connected to the internal structure of the light-emitting film 21; the other part protrudes from the light-emitting film 21 and is embedded in the groove of the second protective ring 22, surrounded and protected by the second protective ring 22. This part is also connected to the second lead-out line 23. The second protective ring 22 also has a slot for the second lead-out line 23 to pass through, so that the entire bottom surface of the second electrode plate 24 is higher than the bottom surface of the light-emitting film 21.

[0050] By embedding the portion of the second electrode sheet 24 protruding from the light-emitting film 21 into the second protective ring 22, the second protective ring 22 is used to surround and protect the second electrode sheet 24, effectively preventing the second electrode sheet 24 from being corroded by the external environment and improving its stability in use.

[0051] It should be noted that the different protruding positions of the electrode plates in the thickness direction of the dimming film 11 and the light-emitting film 21 are determined by the specific structure of each film. The dimming film 11 and the light-emitting film 21 are both relatively thin. The dimming film 11 is typically about 0.38 mm thick, and the first electrode plate 14 can be embedded and arranged by slotting the bottom surface of the film. The light-emitting film 21 is typically about 0.76 mm thick, and its structure will be described later. It is also layered, with upper and lower substrate layers and an intermediate functional layer. Therefore, the second electrode plate 24 is located in the middle and connected to the functional layer.

[0052] Optionally, such as Figure 7 As shown, the light-emitting film 21 includes a first substrate layer 211, an encapsulation layer 212, a circuit layer 213, and a second substrate layer 214 stacked in sequence. A light-emitting chip layer 215 is disposed in the encapsulation layer 212, and a second electrode sheet 24 is disposed at the edge between the circuit layer 213 and the second substrate layer 214.

[0053] In this optional embodiment, the light-emitting film 21 adopts a multi-layer composite structure, consisting of a first substrate layer 211, an encapsulation layer 212, a circuit layer 213, and a second substrate layer 214 from top to bottom. The first substrate layer 211 provides a flat upper bonding surface; the encapsulation layer 212 contains a light-emitting chip layer 215, which serves as a barrier, protection, and support; the circuit layer 213 has power supply lines that are electrically connected to the light-emitting chip on the light-emitting chip layer 215; and the second substrate layer 214 serves as a load-bearing element and provides a flat lower bonding surface. Powering the light-emitting chip through the circuit layer 213 to illuminate the light-emitting unit achieves the starry sky effect.

[0054] The first substrate layer 211 and the second substrate layer 214 can be made of PET material, which is polyethylene terephthalate plastic with a light transmittance of more than 90%.

[0055] Optionally, the thickness of the second protective ring 22 is the same as the thickness of the light-emitting film 21, so that the thickness of the entire light-emitting layer is consistent, which facilitates the design and manufacturing of the stacked structure of the entire glass assembly.

[0056] Optionally, such as Figure 8 As shown, the glass assembly also includes a second protective film 25 and a third protective film 26 disposed at the edge of the light-emitting film 21. The second protective film 25 and the third protective film 26 are both Z-shaped and are respectively attached to the upper and lower sides of the second electrode sheet 24.

[0057] In this optional embodiment, a Z-shaped second protective film 25 and a third protective film 26 are attached to the top and bottom surfaces of the portion of the second electrode sheet 24 that protrudes from the light-emitting film 21, as well as to the corresponding area of ​​the light-emitting film 21 on the second electrode sheet 24. The second protective film 25 and the third protective film 26 are typically made of PI film, which is relatively thin, and are used to protect the connection lines on the second electrode sheet 24. The structure and installation method of the second protective film 25 and the third protective film 26 are similar to those of the first protective film 15, and will not be described in detail here.

[0058] Optionally, the bonding width of the second electrode 24 is not less than 2.5 mm, and increasing the bonding width helps to improve the connection reliability. In addition, the second electrode 24 is held by the light-emitting film 21 with a width of not less than 2 mm, so that even if the width of the second electrode 24 protruding from the light-emitting film 21 is small, it is less affected by external factors.

[0059] Optionally, such as Figure 1 and Figure 9 As shown, both the first structural layer 31 and the second structural layer 32 are provided with light-shielding structures so that the glass assembly forms a light-transmitting area 51 and an opaque area 52. The light-transmitting area 51 is located in the middle of the glass assembly, and the opaque area 52 is arranged circumferentially around the outside of the light-transmitting area 51. The edges of the dimming film 11, the edges of the light-emitting film 21, the first protective ring 12 and the second protective ring 22 are all located within the opaque area 52.

[0060] In this optional embodiment, by providing light-shielding structures on the first structural layer 31 and the second structural layer 32 respectively, the glass assembly forms a light-transmitting area 51 and an opaque area 52. The light-transmitting area 51 is the core field of vision for the driver and passengers, and the opaque area 52 can shield the electrode sheet and lead wire, the protective ring seam, the edge of the diaphragm and the body connection structure, so that only the clean central light-transmitting area is visible in the cabin, which blends naturally with the interior and enhances the texture.

[0061] Specifically, the first structural layer 31 and the second structural layer 32 can be made of glass, and a light-transmitting area 51 with aligned edges is formed by printing a light-shielding coating. In addition, the dimming film 11, the light-emitting film 21, and the light-transmitting area 51 are all rectangular in shape. When this glass assembly is used as a vehicle roof canopy, the first structural layer 31, the dimming layer, the light-emitting layer, and the second structural layer 32 can be stacked sequentially from top to bottom.

[0062] Optionally, such as Figure 1 As shown, the glass assembly also includes a dimming controller 61 and a light-emitting controller 62. Both the dimming controller 61 and the light-emitting controller 62 are disposed in the opaque area 52. The dimming controller 61 is connected to the lead-out end of the first lead-out line 13, and the light-emitting controller 62 is connected to the lead-out end of the second lead-out line 23.

[0063] In this optional embodiment, a dimming controller 61 and a light-emitting controller 62 are provided in the opaque area 52. The dimming controller 61 is connected to the first electrode sheet 14 and the dimming film 11 through the first lead-out line 13 to realize dimming control; the light-emitting controller 62 is connected to the second electrode sheet 24 and the light-emitting film 21 through the second lead-out line 23 to realize light-emitting control, such as presenting different starry sky patterns.

[0064] Optionally, the glass assembly also includes a shielding layer, which is connected between the dimming layer and the light-emitting layer via an adhesive layer 4, and the shielding layer has a light-transmitting structure.

[0065] In this optional embodiment, by setting a shielding layer, inductive interference occurs between the dimming diaphragm 11 and the light-emitting diaphragm 21, affecting the dimming and light-emitting functions. The conductive layer inside the shielding layer is externally grounded through a wire.

[0066] Specifically, the shielding layer can be an ITO transparent conductive film. Using an ultra-thin PET film or ultra-thin glass as the substrate, a conductive layer is deposited on the pretreated substrate surface using a DC magnetron sputtering device with an ITO target as the source. Then, a silicon dioxide protective layer is magnetron sputtered onto the ITO layer surface, or a UV-curable resin is coated, thus preparing the ITO transparent conductive film.
