Description

Technical Field

[0001] This application relates to the technical field of glass, and particularly to a laminated component and a vehicle. Background Art

[0002] In the current lighting application field, such as starry sky ambient lights or side window ambient lights, light guide functional films with high invisibility and high transparency characteristics are often used to make light-emitting patterns.

[0003] However, the bonding force between the light guide functional film and the thermoplastic resin layer is poor. Especially under long-term weather conditions, the two are prone to separation, seriously affecting the product performance. To solve this problem, the light guide functional film is usually encapsulated between two pieces of glass through an adhesive material so that it is not exposed and does not come into contact with the outside world.

[0004] However, the above solution will cause the light source to be blocked by the adhesive material when the external light source acts, preventing it from contacting the light guide functional film and hindering the light propagation, making it difficult to achieve the high-invisibility ambient light function of the light guide functional film. Summary of the Invention

[0005] Based on this, it is necessary to provide a laminated component and a vehicle for the above technical problems.

[0006] In a first aspect, this application provides a laminated component, including a first transparent substrate, a first adhesive layer, a second adhesive layer, and a second transparent substrate stacked in sequence;

[0007] Among them, the material of the light guide component is an inorganic material, and the light guide component is used to introduce an external light source.

[0008] In one embodiment, the laminated component further includes a light guide functional film disposed on the same layer as the light guide component;

[0009] Among them, the light guide component is disposed on the periphery of the light guide functional film and is used to introduce the external light source into the light guide functional film.

[0010] In one embodiment, the proximal end surface of the light guide component close to the light guide functional film contacts the light guide functional film, and the distal end surface of the light guide component away from the light guide functional film contacts the external light source.

[0011] In one embodiment, the thickness difference between the light guide component and the light guide functional film is within 20% of the thickness of the light guide functional film.

[0012] In one embodiment, the thickness of the light guide component is equal to the thickness of the light guide functional film.

[0013] In one embodiment, the width of the light guide component is greater than or equal to 2 mm; preferably, the width of the light guide component is greater than or equal to 5 mm; more preferably, the width of the light guide component is greater than or equal to 10 mm.

[0014] In one embodiment, when the number of light guiding components is more than one, the light guiding components are evenly arranged around the light guiding functional film;

[0015] When the number of light guiding components is one, the light guiding component is arranged in a partial peripheral area of the light guiding functional film.

[0016] In one embodiment, the surface of the light guiding component has a light guiding structure.

[0017] In one embodiment, the outer edges of the first transparent substrate, the first adhesive layer, the light guiding component, the second adhesive layer, and the second transparent substrate are flush with each other.

[0018] In one embodiment, the outer edges of the first adhesive layer, the light guiding component, the second adhesive layer, and the second transparent substrate are flush with each other, and the projection of the first transparent substrate on the second transparent substrate covers the area where the second transparent substrate is located.

[0019] In a second aspect, the present application further provides a vehicle, including the laminated component in the above embodiment.

[0020] The above laminated component and vehicle have at least the following beneficial effects:

[0021] Based on the characteristic that the bonding force between the inorganic material and the thermoplastic resin is strong, the light guiding component is more stable when combined with the upper and lower adhesive layers, ensuring the stability of the entire product structure. During long-term use, even under the influence of external factors such as vibration and temperature changes, the light guiding component is not easily separated from the adhesive layer, ensuring the structural mechanical properties of the product. With the strong bonding force with the adhesive layer and its own good performance, the use of inorganic materials for the light guiding component can effectively ensure the long-term weather resistance of the product. When facing different climate conditions and environmental factors, such as high temperature, high humidity, ultraviolet radiation, etc., the light guiding component can stably play its role and will not age or fail rapidly due to changes in the external environment, extending the service life of the product, thereby avoiding the problems of insufficient structural mechanical properties and long-term weather resistance caused by poor bonding force between the light guiding functional film and the thermoplastic resin, and at the same time can meet the light guiding and light emitting requirements to achieve the atmosphere light effect.

[0043] In an exemplary embodiment, as Figure 1 shown, this application provides a laminated component, including a first transparent substrate 2, a first adhesive layer 4, a light guide component 6, a second adhesive layer 8 and a second transparent substrate 10 stacked in sequence; wherein, the material of the light guide component is an inorganic material, and the light guide component is used to introduce an external light source 300.

[0044] Among them, both the first transparent substrate 2 and the second transparent substrate 10 can refer to glass substrates. Both the first adhesive layer 4 and the second adhesive layer 8 can be composed of one or more of thermoplastic resin materials such as PVB (Polyvinyl Butyral), PVC (Polyvinylchloride), EVA (Ethylene Vinyl Acetate Copolymer resin), COP (Cyclo Olefin Polymer), TPU (Thermoplastic Urethane), etc. The light guide component 6 can be an inorganic light guide layer with a light guiding function, specifically, the light guide component 6 composed of inorganic glass; the external light source 300 can refer to a light strip composed of an LED light emitting diode component layer.

[0045] Exemplarily, as Figure 1 shown, the laminated component includes a first transparent substrate 2, a first adhesive layer 4, a light guide component 6, a second adhesive layer 8 and a second transparent substrate 10, and the upper and lower surfaces of the light guide component 6 are respectively in contact with the first adhesive layer 4 and the second adhesive layer 8. By selecting a light guide component 6 made of an inorganic material to realize the introduction of the external light source 300, surface structuring treatment schemes such as chemical etching, silk screen spraying, laser engraving, etc. can also be carried out on some areas of the smooth surface of the light guide component 6, forming as Figure 2 and Figure 3The luminous patterns such as the appearance of the polar star shown are irradiated by the external light source 300 to the light guide component 6, and the luminous effect of the area is achieved at the polar star, so as to achieve an atmosphere light effect similar to that achieved by the light guide functional film 12. Among them, for the shape, quantity and installation position of the light guide component 6, they can be adaptively designed according to the actual application scenario. For example, as Figure 2 or Figure 3 shown, no specific limitations are made here.

[0046] Based on the characteristic that the inorganic material has a strong bonding force with the thermoplastic resin, the above-mentioned laminated component makes the light guide component 6 more stable when combined with the upper and lower bonding layers, ensuring the stability of the entire product structure. During long-term use, even affected by external factors such as vibration and temperature changes, the light guide component 6 is not easily separated from the bonding layer, ensuring the structural mechanical properties of the product. With the strong bonding force with the bonding layer and its own good performance, the light guide component 6 made of inorganic material can effectively ensure the long-term weather resistance of the product. When facing different climate conditions and environmental factors, such as high temperature, high humidity, ultraviolet irradiation, etc., the light guide component 6 can stably play its role and will not age or fail rapidly due to changes in the external environment, extending the service life of the product, thus avoiding the problems of insufficient structural mechanical properties and long-term weather resistance of the product caused by the poor bonding force between the light guide functional film 12 and the thermoplastic resin, and at the same time can meet the light guide and luminous requirements to achieve the atmosphere light effect.

[0047] In an exemplary embodiment, as Figure 4 shown, the laminated component further includes a light guide functional film 12 arranged on the same layer as the light guide component 6; wherein, the light guide component 6 is arranged on the periphery of the light guide functional film 12 and is used to introduce the external light source into the light guide functional film 12.

[0048] Among them, the light guide functional film 12 may refer to a film formed by making a luminous pattern on an organic functional film such as PC (Polycarbonate, polycarbonate resin), PET (polyethylene glycol terephthalate, polyethylene terephthalate resin) and PS (Polystyrene, polystyrene).

[0049] Exemplarily, although directly selecting the light guide component 6 composed of inorganic materials can ensure the structural mechanical properties and long-term weather resistance of the product and meet the atmosphere light requirements at the same time, due to considerations such as different design requirements or different cost requirements, there is still a certain market demand for the laminated component using the light guide functional film 12. Therefore, for the laminated component with the need to use the light guide functional film 12, this embodiment provides an implementation solution to ensure the structural mechanical properties and long-term weather resistance of the product and meet the atmosphere light requirements at the same time when the laminated component uses the light guide functional film 12. Specifically, asFigure 4 and Figure 5 As shown in Figure 5 , the laminated component includes a first transparent substrate 2, a first adhesive layer 4, a light guide component 6, a second adhesive layer 8, a second transparent substrate 10, and a light guide functional film 12. Among them, as Figure 4 shown, from the perspective of the thickness cross-section, the light guide component 6 and the light guide functional film 12 are arranged on the same layer. As Figure 5 shown, from the top view, the light guide component 6 is arranged on the periphery of the light guide functional film 12. For the light guide functional film 12 encapsulated between the interlayers, by arranging the light guide component 6 on the periphery of the light guide functional film 12, when the external light source 300 irradiates, it can be introduced into the internal light guide functional film 12 through the light guide component 6, so that the light guide functional film 12 can play a lighting effect. Secondly, in the above structure, in addition to being able to achieve an effective light guiding effect, the light guide component 6 can also act as an edge sealing structure for the light guide functional film 12, preventing the internal light-emitting or light-reflecting materials or other functional materials of the light guide functional film 12 from directly contacting the adhesive layer, affecting the product performance and lifespan of the light guide functional film 12.

[0050] In this embodiment, by setting the light guide component 6 to connect the optical waveguide region blocked by the adhesive layer between the light guide functional film 12 and the external light source 300, the light guide component 6 plays a role in introducing the external light source 300 into the internal light guide functional film 12, so that the light guide component 6 connects the optical waveguide between the external light source 300 and the light guide functional film 12, thereby solving the problem that the light guide functional film 12 encapsulated in the adhesive layer cannot receive the external light source 300. At the same time, since the light guide component 6 is arranged around the light guide functional film 12 and bonded with the adhesive layer, an edge sealing structure composed of the light guide component 6 is formed, ensuring the structural mechanical properties and long-term weather resistance of the product.

[0051] In an exemplary embodiment, as Figure 4 and Figure 5 shown, the proximal end surface of the light guide component 6 close to the light guide functional film 12 contacts the light guide functional film 12, and the distal end surface of the light guide component 6 far from the light guide functional film 12 contacts the external light source.

[0052] Exemplarily, the proximal end surface of the light guide component 6 close to the light guide functional film 12 contacts the light guide functional film 12, while the distal end surface of the light guide component 6 far from the light guide functional film 12 contacts the external light source 300, and the upper and lower surfaces of the light guide component 6 respectively contact the first adhesive layer 4 and the second adhesive layer 8. Among them, for the contact method between the light guide component 6 and the light guide functional film 12, a flush and mutual contact or an inlaid contact or other contact methods beneficial to light wave guiding can be adopted.

[0053] In this embodiment, a light guide component 6 is provided to connect the optical waveguide area blocked by the adhesive layer between the light guide functional film 12 and the external light source 300. One side of the light guide component 6 contacts the external light source 300, and the other side contacts the light guide functional film 12 encapsulated in the adhesive layer. The direct contact can minimize the loss of light during transmission. When the external light source contacts the distal end surface of the light guide component 6, the light can be more efficiently coupled into the light guide component 6, reducing the reflection and refraction losses caused by the air gap or other media, and ensuring that the light enters the light guide component 6 with a higher intensity. The proximal end surface of the light guide component 6 is in direct contact with the light guide functional film 12, which can smoothly transmit the light from the light guide component 6 to the light guide functional film 12, avoiding the scattering and energy loss of light at the interface, thereby improving the light guide efficiency of the entire light guide system, so that the light guide functional film 12 can receive and transmit light more evenly and effectively, and achieve a good light guide effect.

[0054] In an exemplary embodiment, the thickness difference between the light guide component 6 and the light guide functional film 12 is within 20% of the light guide functional film 12 .

[0055] In this embodiment, if the thickness difference between the light guide component 6 and the light guide functional film 12 is not large, because the thickness is similar, when the light guide component 6, the light guide functional film 12 and other components (such as the first transparent substrate 2, the second transparent substrate 10, the first adhesive layer 4 and the second adhesive layer 8) are packaged and combined, it is easier to operate, and the cooperation between the components is more consistent. In the actual production process, whether it is assembly or subsequent processing, the inconvenience caused by the large thickness difference can be reduced, and the production efficiency can be improved. Secondly, for actual products, the appropriate thickness ratio can ensure the stability of the overall structure of the product. The thickness of the light guide component 6 and the light guide functional film 12 is similar. When affected by external forces (such as vibration, extrusion, etc.) or environmental factors (such as temperature changes, humidity changes, etc.), the stress distribution between the components is more uniform, and it is not easy to have local stress concentration caused by excessive thickness differences, thereby ensuring the stability of the product during use, reducing the risk of product damage, and extending the service life of the product.

[0056] In an exemplary embodiment, the thickness of the light guide component 6 is equal to the thickness of the light guide functional film 12 .

[0057] In this embodiment, when the thicknesses of the light guide component 6 and the light guide functional film 12 are similar, it is further specified that they have the same thickness. In addition to enabling easy encapsulation in the production process and making the actual product more stable, it can also achieve better light propagation effects. Specifically, when the light guide component 6 and the light guide functional film 12 have the same thickness, the interface for light propagation between the two is more uniform and flat. This helps reduce the refraction and reflection losses of light at the interface between different media, enabling light to be more efficiently conducted from the light guide component 6 to the light guide functional film 12, thereby improving the overall light guide efficiency, making the lighting effect of the atmosphere light brighter and more uniform, and better meeting the user's requirements for the lighting effect.

[0058] In an exemplary embodiment, as Figure 4 and Figure 5 shown, the width L of the light guide component 6 is greater than or equal to 2 mm; preferably, the width L of the light guide component 6 is greater than or equal to 5 mm; more preferably, the width L of the light guide component 6 is greater than or equal to 10 mm.

[0059] Exemplarily, if the width L of the light guide component 6 is too small, the contact area with the adhesive layer will be insufficient. During long-term use, affected by environmental factors such as temperature and humidity changes, the small contact area is difficult to withstand the stress generated by the thermal expansion and contraction of the material, and it is easy for the light guide component 6 to separate or fall off from other components, thereby affecting the performance of the light guide functional film 12 after encapsulation and reducing the long-term weather resistance of the product. In addition, if the width L of the light guide component 6 is too narrow, the ability to collect light from the external light source 300 will become weaker, and the amount of light conducted to the light guide functional film 12 will decrease, resulting in a decrease in the clarity of the light-emitting pattern and uneven brightness, making it impossible to achieve the ideal light guide and light-emitting effects and difficult to meet the user's requirements for the lighting effect of the product. When the width L of the light guide component 6 is larger, the contact area between the light guide component 6 and the adhesive layer is larger, and the connection is more stable. During long-term use, affected by environmental factors such as temperature and humidity changes, the larger contact area can reduce the stress concentration generated by the thermal expansion and contraction of the material, and avoid the separation or falling off of the light guide component 6 from other components, thereby ensuring the stable performance of the light guide functional film 12 after encapsulation and improving the long-term weather resistance of the product. Moreover, the wider light guide component 6 can collect more light from the external light source 300 and conduct it to the light guide functional film 12 more efficiently. Taking the in-vehicle ambient light as an example, the wider light guide component 6 can make the light more evenly distributed on the light guide functional film 12, making the light-emitting pattern clearer and the brightness more uniform, enhancing the visual effect of the ambient light and meeting the user's requirements for high-quality lighting effects. In some application scenarios with high requirements for structural strength and light guide performance, such as large display screens and high-end automotive interiors, the light guide component 6 with a larger width L can better meet these special requirements. Therefore, the width L of the light guide component 6 is greater than or equal to 2 mm; preferably, the width L of the light guide component 6 is greater than or equal to 5 mm; more preferably, the width L of the light guide component 6 is greater than or equal to 10 mm.

[0060] In an exemplary embodiment, as Figure 4 and Figure 5 shown, when the number of light guide components 6 is multiple, the light guide components 6 are uniformly arranged on the periphery of the light guide functional film 12; when the number of light guide components 6 is one, as Figure 6 shown, the light guide component 6 is arranged in a partial peripheral area of the light guide functional film 12.

[0061] Exemplarily, in some scenarios with relatively simple requirements for the ambient light effect, such as ordinary home interior decoration, it may only be necessary to arrange an inorganic light guide layer on one side of the product to meet the needs of lighting and creating an atmosphere, saving costs. In a scenario like the interior of a car, where the requirements for the ambient light effect are relatively high and the space is complex, arranging the inorganic light guide layer on multiple sides can allow light to be introduced from different directions, making the light-emitting effect of the in-vehicle ambient light more three-dimensional and uniform. Therefore, the number and layout position of the light guide components 6 can be selected according to the design requirements of the application scenario.

[0062] In an exemplary embodiment, Figure 1 and Figure 4 As shown, outer edges of the first transparent substrate 2, the first adhesive layer 4, the light guide assembly 6, the second adhesive layer 8 and the second transparent substrate 10 are flush with each other.

[0063] Exemplarily, the design that the outer edges of the first transparent substrate 2, the first adhesive layer 4, the light guide component 6, the second adhesive layer 8 and the second transparent substrate 10 are flush with each other can make the entire laminated component structure more regular, and the connection between the light guide component 6 and the first transparent substrate 2 and the second transparent substrate 10 is tighter and more stable, which helps to disperse external forces and reduce stress concentration points. When subjected to external forces such as vibration and impact, it can better maintain the integrity of the overall structure and reduce the risk of product damage. In addition, when the laminated component includes a light guide functional film 12, when the light of the external light source 300 collected by the light guide component 6 is transmitted to the light guide functional film 12, the refraction and scattering of light caused by the uneven outer edges of the first transparent substrate 2, the second transparent substrate 10 and the light guide component 6 are reduced, ensuring that the light is efficiently and evenly transmitted, improving the luminous effect of the light guide functional film 12, and making the luminous pattern of the atmosphere light clearer and more uniform in brightness.

[0064] In an exemplary embodiment, Figures 6 to 8 As shown, the outer edges of the first adhesive layer 4 , the light guide assembly 6 , the second adhesive layer 8 and the second transparent substrate 10 are flush with each other, and the projection of the first transparent substrate 2 on the second transparent substrate 10 covers the area where the second transparent substrate 10 is located.

[0065] Exemplarily, the outer edges of the first adhesive layer 4, the light guide component 6, the second adhesive layer 8 and the second transparent substrate 10 are flush with each other, and the projection of the first transparent substrate 2 on the second transparent substrate 10 covers the area where the second transparent substrate 10 is located, which may specifically refer to any of the following situations: for example, Figure 6 As shown, when the outer edges of the first adhesive layer 4, the light guide component 6, the second adhesive layer 8 and the second transparent substrate 10 are flush with each other, the outer edges of one side of them are retracted by a preset dimension X relative to the outer edge of the first transparent substrate 2, and an external light source 300 is arranged on the retracted area side to realize the optical waveguide function. In a specific embodiment, the thickness of the first transparent substrate 2 and the second transparent substrate 10 can be 0.1 mm. For another example, Figure 7 As shown, when the outer edges of the first adhesive layer 4, the light guide component 6, the second adhesive layer 8 and the second transparent substrate 10 are flush with each other, the outer edges on both sides thereof are retracted by a preset dimension X relative to the outer edge of the first transparent substrate 2, and an external light source 300 is arranged on the retracted area side to realize the optical waveguide function. Figure 8As shown, when the outer edges of the first adhesive layer 4, the light guide component 6, the second adhesive layer 8, and the second transparent substrate 10 are flush with each other, they are all recessed by a preset dimension X relative to the outer edge of the first transparent substrate 2. At the same time, an external light source 300 is provided on the side of the recessed area to achieve the function of an optical waveguide. Through the recessed structure as exemplified above, light is reflected and refracted multiple times within the transparent substrate, increasing the contact opportunity between the light and the light guide functional film 12, making the light more evenly distributed on the light guide functional film 12, thereby improving the light guide effect and making the light-emitting pattern of the atmosphere light clearer and the brightness more uniform.

[0066] In an exemplary embodiment, the surface of the light guide component 6 has a light guide structure.

[0067] Exemplarily, the upper and lower surfaces of the light guide component 6 can be treated by chemical etching, printing, laser engraving, etc. to form a light guide structure on the surface of the light guide component 6. After being treated by chemical etching, printing, laser engraving, etc., the surface microstructure of the inorganic light guide layer changes to form a light guide structure. These light guide structures can change the propagation path of light within the light guide layer, causing the light to be reflected and refracted multiple times during propagation, increasing the propagation distance of the light within the light guide layer, thereby increasing the probability of the light being received by the light guide functional film 12 and improving the overall light guide efficiency, making the light-emitting effect of the atmosphere light brighter. Different treatment methods can regulate the light, making the light more evenly distributed within the inorganic light guide layer. For example, by treating the contact surface between the light guide component 6 and the light guide functional film 12, the originally concentrated light can be diffused, so that after the light is conducted to the light guide functional film 12, a more uniform light-emitting effect can be formed, avoiding the situation of too high or too low local brightness.

[0068] In an exemplary embodiment, the light guide component 6 is a light guide component 6 that has been subjected to surface stress strengthening treatment.

[0069] In this embodiment, subjecting the light guide component 6 to surface stress strengthening treatment can improve the mechanical strength of the light guide component 6 and enhance its resistance to bending and stretching. When manufacturing a hyperbolic product, the light guide component 6 can better withstand the stress changes during the processing, and is not prone to problems such as cracking and deformation, ensuring good structural stability under the hyperbolic shape and meeting the manufacturing requirements of the complex shape of the hyperbolic product. In some manufacturing scenarios of hyperbolic products with low requirements for surface stress strengthening, the light guide component 6 can also not be treated, which can simplify the manufacturing process, reduce costs, and at the same time ensure a certain flexibility, making it more convenient for the light guide component 6 to fit the special shape of the hyperbolic product and improving production efficiency.

[0070] In an exemplary embodiment, as Figure 9 shown, the outer shape of the light guide component 6 is an irregular shape with an irregular structure.

[0071] In this embodiment, the light guide component 6 with an irregular special-shaped structure can meet diverse requirements. For example, during the automotive interior design, it can fit the structural nesting requirements of complex interiors. Secondly, the light guide component 6 can also be chemically tempered to further enhance the structural stability of the light guide component 6 under the irregular special-shaped structure.

[0072] In an exemplary embodiment, the present application also provides a vehicle, including the laminated component as described in the above embodiment.

[0073] Applying the laminated component in the above embodiment in a vehicle can not only solve the light guiding problem of the light guiding functional film in vehicle applications with the help of the light guide component, creating an invisible and comfortable driving atmosphere, but also solve the problem of insufficient long-term weather resistance with its optimized structural design, enhancing the overall stability and durability to adapt to the complex environment during vehicle driving.

[0074] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in the present application.

[0075] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
