[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0029] Please see Figure 1In one embodiment, this application provides a light-transmitting element 10, which can adopt a reflective levitation imaging structure design. The light-transmitting element 10 may include a first light-transmitting body 100, an image layer 200, an optical film 300, and a second light-transmitting body 400 stacked sequentially. The optical film 300 is configured such that incident light entering from the first light-transmitting body 100 and passing through the image layer 200 can be reflected by the optical film 300 to form a levitation image S on one side of the first light-transmitting body 100. The levitation image S can be presented using natural ambient light, with a simple structure and no need for additional lighting. In some embodiments, the image layer 200 may be disposed on the optical film 300.
[0030] Alternatively, please see Figure 2 In another embodiment, this application also provides a light-transmitting element 10 structure for transmissive levitation imaging. The light-transmitting element 10 may include a first light-transmitting body 100, an optical film 300, an image layer 200, and a second light-transmitting body 400 stacked sequentially. The optical film 300 is configured such that incident light entering from the second light-transmitting body 400 and passing through the image layer 200 can be transmitted through the optical film 300 to form a levitation image S on one side of the first light-transmitting body 100. Specifically, the light enters from the side away from the observation, which can effectively avoid the interference of strong light on the observation side on the imaging, resulting in higher contrast and clarity of the levitation image S.
[0031] It should be noted that after the incident light passes through the image layer 200, it hits the optical film 300. The optical film 300 can realize the reflection or transmission of the suspended image S through the appropriate structural configuration.
[0032] The light-transmitting component 10 of this application, by sandwiching a graphic layer 200 and an optical film 300 between the first light-transmitting body 100 and the second light-transmitting body 400, enables the corresponding floating image S of the graphic layer 200 to be presented with the help of the optical film 300, transforming the traditional planar graphic information into a three-dimensional floating visual effect, greatly improving the aesthetics and technological feel of the content presented in the graphic layer 200, and meeting the exterior design requirements of high-end vehicles.
[0033] In addition, since the graphic layer 200 is sandwiched between the first light-transmitting body 100 and the second light-transmitting body 400, it forms a double-layer glass sealed protective structure, which effectively avoids damage to the graphic layer 200 caused by external scratches, acid and alkali corrosion, high temperature aging and other factors, and significantly improves the reliability and long-term stability of the floating image S function presentation.
[0034] Please see Figure 3In some embodiments, for the structure of the light-transmitting element 10 in reflective levitation imaging, corresponding to the scheme that "the light-transmitting element 10 may include a first light-transmitting body 100, an image layer 200, an optical film 300, and a second light-transmitting body 400 stacked sequentially. The optical film 300 is configured such that incident light entering from the first light-transmitting body 100 and passing through the image layer 200 can be reflected by the optical film 300 to form a levitation image S on one side of the first light-transmitting body 100", the light-transmitting element 10 may also include a dimming layer 500, which is sandwiched between the first light-transmitting body 100 and the second light-transmitting body 400, and the dimming layer 500 is disposed on the side of the optical film 300 facing away from the second light-transmitting body 400, so that the dimming layer 500 can adjust the reflected light.
[0035] Understandably, the specific implementation of the dimming layer 500 being disposed on the side of the optical film 300 opposite to the second light-transmitting body 400 can be as follows: Figure 3 As shown, the dimming layer 500 is disposed between the graphic layer 200 and the first light-transmitting body 100. Of course, in some other embodiments, the dimming layer 500 can also be disposed between the graphic layer 200 and the optical film 300, which can also play a role in adjusting light, and there is no limitation here.
[0036] Specifically, the dimming layer 500 can control its own occlusion state to change the visibility of the image layer 200, such as making it visible or invisible, or changing its brightness, viewing angle, floating height, or clarity. The addition of the dimming layer 500 gives the light-transmitting component 10 the ability to actively control the floating image S, allowing it to switch between showing and hiding the image according to actual usage needs. This meets the usage needs of vehicles in different scenarios, such as hiding the image while the vehicle is in motion to avoid interfering with the driver's vision, and showing the image when parked to enhance brand recognition. At the same time, by adjusting the light transmittance of the dimming layer 500, it can adapt to environments with different light intensities, ensuring that the floating image S maintains a clear presentation even in low-light environments such as cloudy days and evenings, further improving the product's environmental adaptability.
[0037] Please see Figure 4 In some embodiments, for the structure of the light-transmitting element 10 in the transmissive levitation imaging, corresponding to the scheme that "the light-transmitting element 10 may include a first light-transmitting body 100, an optical film 300, an image layer 200 and a second light-transmitting body 400 stacked in sequence, and the optical film 300 is configured such that incident light rays enter from the second light-transmitting body 400 and pass through the image layer 200, and can be transmitted through the optical film 300 to form a levitation image S on one side of the first light-transmitting body 100", the light-transmitting element 10 may also include a light source layer 600, which is sandwiched between the first light-transmitting body 100 and the second light-transmitting body 400, and the light source layer 600 is disposed on the side of the image layer 200 away from the optical film 300.
[0038] Specifically, the light source layer 600 emits its own light to supplement the intensity of the incident light, thereby improving the presentation of the levitated image S.
[0039] It is worth noting that in this embodiment, the first light-transmitting element 100 is generally configured to face the outside of the vehicle, and the second light-transmitting element 400 is generally configured to face the inside of the vehicle. This allows the suspended image S to be displayed and viewed by the user from the outside of the vehicle. Therefore, the incident light needs to enter from the inside of the vehicle. In this embodiment, by setting the light source layer 600 on the side of the image layer 200 away from the optical film 300, the light source layer 600 acts as an active supplementary lighting structure, completely solving the problem of insufficient light in low-light environments such as nighttime, tunnels, and underground parking garages for transmissive imaging. This ensures that the suspended image S can be clearly displayed at all times and in all scenarios, thereby improving the display stability of the suspended image S. In addition, the light source layer 600 can provide a uniform surface light source, avoiding local brightness differences in the image caused by uneven light, and improving the overall display quality of the suspended image S. Furthermore, the light from the light source layer 600 enters from inside the light-transmitting element 10, effectively avoiding reflection interference from external light sources, further ensuring the clarity of the image.
[0040] Please continue reading. Figure 5 Based on the aforementioned configuration of the light source layer 600, in some embodiments, the light-transmitting element 10 may further include a dimming layer 500. The dimming layer 500 is sandwiched between the first light-transmitting body 100 and the second light-transmitting body 400, and the dimming layer 500 is disposed on the side of the light source layer 600 away from the second light-transmitting body 400. This helps to adjust the intensity of the light emitted by the light source layer 600, thereby achieving different presentation effects of the corresponding floating image S of the graphic layer 200.
[0041] Specifically, the combination of the dimming layer 500 and the light source layer 600 forms a dual light control system of "active supplementary lighting + precise dimming". Compared with a single supplementary lighting or dimming structure, this system can achieve fine adjustment of light intensity and transmittance. It can automatically adapt to the best imaging parameters according to changes in ambient light. At the same time, it can achieve multi-dimensional control of the visibility, brightness, and clarity of the suspended image S, which greatly improves the product's intelligence level and flexibility of use. In addition, the combination of the two can effectively avoid glare caused by excessive light from the light source layer 600, ensuring the comfort and aesthetics of the imaging effect.
[0042] Please see Figures 1-5In some embodiments, the optical film 300 may include a substrate layer 310 and a lens array layer 320. The image layer 200 and the lens array layer 320 are respectively disposed on opposite sides of the substrate layer 310. In this way, the substrate layer 310 can provide a good foundation for the lens array layer 320, ensuring the structural flatness and positional stability of the lens array layer 320, improving the stability of the lens array layer 320 in light processing, and avoiding image ghosting and distortion problems caused by deformation or displacement of the lens array layer 320. At the same time, the substrate layer 310 can be configured to use a high-transmittance optical material, which can reduce light transmission loss, ensure the intensity of imaging light, and improve the presentation effect of the levitation image S. As the core structure of optical imaging, the lens array layer 320 can realize the directional refraction and convergence of light, accurately converting the pixel information of the image layer 200 into the levitation image S, ensuring the three-dimensional levitation effect and positional accuracy of the image.
[0043] In some embodiments, the height of the suspended image S relative to the first light-transmitting body 100 can be configured to a preset height h, which can meet the user's presentation requirements for the suspended image S.
[0044] It should be noted that the aforementioned preset height h can refer to the height of any image point in the suspended image S relative to the first light-transmitting body 100. In other words, the suspended image S can be presented as having multiple image parts, each distributed at a different height, or the suspended image S can have a continuously changing height.
[0045] In some embodiments, the preset height h can be in the range of 1mm-10mm, 10mm-20mm, 20mm-50mm, 50mm-100mm, 100-200mm, 200-500mm, or greater than 500mm. This makes the height configuration of the suspended image S a more reasonable and comfortable range. A reasonable suspension height setting allows the observer to obtain a comfortable stereoscopic visual experience at a normal observation distance, avoiding the visual oppression caused by the suspension height being too close or the image blurring caused by the suspension height being too far. At the same time, different height ranges can adapt to the glass requirements of different parts of the vehicle, such as the windshield and side window glass, improving the adaptability of the product.
[0046] It should be noted that the suspended image S can be, but is not limited to, configured on both sides of the light-transmitting element 10 for a suspended configuration. In some embodiments, the first light-transmitting body 100 can be configured on the front side of the light-transmitting element 10, where the aforementioned preset height h refers to the height of any image point in the suspended image S above the front side of the light-transmitting element 10. In other embodiments, the first light-transmitting body 100 can be configured on the back side of the light-transmitting element 10, where the aforementioned preset height h refers to the height of any image point in the suspended image S below the back side of the light-transmitting element 10.
[0047] Please see Figure 6 In some embodiments, the suspending image S has projection points that correspond one-to-one with the pixels of the image layer 200. The line connecting the projection points and the pixels forms a preset angle θ with the perpendicular line of the first light-transmitting body 100. The preset angle θ can be ≥50°, ≥60°, ≥70°, ≥80°, or ≥90°. This helps to configure the suspending position of the suspending image S in a more reasonable and comfortable position. The precise setting of the preset angle θ allows the imaging position of the suspending image S to fall within the observer's optimal visual range, ensuring that the observer can clearly see the complete suspending image S from different angles. This improves the viewing angle of the image and avoids the problem of narrow viewing range caused by too small an angle. At the same time, this angle design matches the light control characteristics of the optical film 300, which can reduce the refraction loss of light, ensure the intensity of the imaging light, and further improve the clarity of the image.
[0048] In some embodiments, the graphic layer 200 can be configured with different colors to meet the personalized needs of customers and consumers.
[0049] Optionally, the graphic layer 200 is predominantly black. In other embodiments, the graphic layer 200 may also be implemented in other colors, such as red, blue, white, yellow, purple, orange, green, etc. Optionally, the graphic layer 200 may be, but is not limited to, ink-filled.
[0050] Specifically, the multi-color configuration of the graphic layer 200 allows the vehicle glass to match different brand logos, body colors and personalized design needs, greatly improving the product's customization capabilities and market adaptability. Black, as the preferred color, can effectively improve the contrast between the graphic layer 200 and the background, ensuring the visual recognition of the floating image S in various lighting environments.
[0051] In some embodiments, the resolution of the suspending image S is configured to be greater than or equal to a reference value R0, wherein the reference value R0 corresponds to a microstructure feature size ranging from 0.1μm to 0.3μm, 0.3μm to 0.7μm, or 0.7μm to 1μm, which helps to ensure the clarity of the suspending image S.
[0052] In some embodiments, the optical film 300 is provided with a first positioning point, and the graphic layer 200 is provided with a second positioning point. The first positioning point and the second positioning point are aligned and positioned with each other, which helps to improve the positioning accuracy between the graphic layer 200 and the optical film 300, avoids image ghosting, offset, and distortion caused by misalignment, and ensures the presentation effect of the suspended image S. At the same time, the precise positioning structure can simplify the production and assembly process of the light-transmitting component 10, improve production efficiency, and reduce the product defect rate caused by assembly errors.
[0053] Please see Figure 7 In some embodiments, the graphic layer 200 can be disposed on the inner surface of the first light-transmitting body 100. Optionally, the graphic layer 200 can be sintered onto the inner surface of the first light-transmitting body 100 by printing. This arrangement allows the graphic layer 200 to form an integrated structure with the first light-transmitting body 100, reducing the layer thickness of the light-transmitting element 10, which helps to improve the overall light transmittance of the glass. At the same time, it reduces the light refraction loss caused by the bonding of multiple layers, further improving the imaging effect. It is worth noting that the configuration of the graphic layer 200 on the inner surface of the first light-transmitting body 100 requires high alignment accuracy between the lens array layer 320 and the pattern. Therefore, the second positioning point of the graphic layer 200 can be adjusted to be disposed on the edge printing area on the first light-transmitting body 100. This helps to indirectly perform positioning calibration through the assembly operation of the first light-transmitting body 100 when positioning the graphic layer 200 and the optical film 300, thus improving the ease of positioning the graphic layer 200 and the optical film 300. Optionally, the second positioning point may be configured, but is not limited to, as a cutout structure of a "+" shape extracted from the first light-transmitting body 100.
[0054] In some embodiments, the graphic layer 200 can be, but is not limited to, set on the inner surface of the first light-transmitting body 100 by means of embossing and scraping. Multiple manufacturing methods can adapt to different production processes and graphic design requirements, improving production flexibility. At the same time, processes such as embossing and scraping can ensure the structural flatness and pixel accuracy of the graphic layer 200, providing a foundation for clear levitation imaging.
[0055] In some embodiments, the lens array layer 320 may include a plurality of microlens structures arranged in a periodic manner. The period of the lens array layer 320 is in the range of less than 1μm, 1μm-10μm, 10μm-20μm, 20μm-30μm, 30μm-40μm, 40μm-50μm, 50μm-100μm, 100μm-200μm, 200μm-300μm, or 300μm-500μm. This helps to improve the uniformity and regularity of the arrangement of the plurality of microlens structures, ensure that the light control effect of each microlens structure is consistent, improve the processing effect of light and the suspended image S, and avoid the problems of uneven image brightness and local deformation caused by uneven microlens spacing. At the same time, different spacing ranges can adapt to the needs of suspended images S with different resolutions and sizes, thus improving the adaptability of the lens array layer 320.
[0056] It should be noted that when the period of the microstructures in the lens array layer 320 is on the order of the visible light band, according to the scattering principle, it is easy to cause light scattering. Therefore, the smaller the period value of the lens array layer 320, such as the period value of the lens array layer 320 being less than 1 μm, helps to reduce the light scattering in the lens array layer 320, and further helps to reduce the overall haze of the light-transmitting member 10, meeting the user's requirements. In some embodiments, the haze of the light-transmitting member 10 can take values such as ≤80%, ≤50%, ≤20%, ≤10%, ≤5% or ≤2%, etc.
[0057] Please refer to Figure 6 , in some embodiments, the microlens structure has a preset focal length f, and the preset focal length f is configured to satisfy . Where u is the distance from the graphic layer 200 to the lens array layer 320, and v is the distance from the floating image S to the lens array layer 320. Precise focal length setting can ensure the accuracy of optical imaging, enabling the floating image S to be presented at the preset position and size, and avoiding image blurring, offset or deformation.
[0058] Please continue to refer to Figure 6 , in some embodiments, the distance u from the graphic layer 200 to the lens array layer 320 should satisfy f < u < 2f. This distance setting can achieve a three-dimensional floating magnification presentation of the information of the graphic layer 200, enhancing the visual three-dimensional sense and recognition of the image.
[0059] In some embodiments, the value range of the preset focal length f can be 10 μm - 20 μm, 20 μm - 50 μm, 50 μm - 60 μm, 60 - 100 μm, 100 μm - 200 μm, 200 - 300 μm, 300 μm - 500 μm or f ≥ 500 μm. Different focal length values can be adapted to different floating heights and magnification requirements, meeting diverse imaging design requirements.
[0060] In some embodiments, the first light-transmitting body 100 has a preset light transmittance T, and the value range of the preset light transmittance T is T ≥ 80%, T ≥ 90% or T ≥ 92%. This helps to improve the imaging effect of the floating image S. The first light-transmitting body 100 with a high light transmittance can reduce the transmission loss of incident light and imaging light, ensure the intensity of light, make the floating image S clearer and brighter. At the same time, the high light transmittance also meets the optical performance requirements of vehicle glass, ensuring the field of vision clarity during vehicle driving, taking into account both the imaging effect and driving safety.
[0061] In some embodiments, a magnification ratio M is configured between the floating image S and the graphic layer 200, and the magnification ratio M is configured as Where d0 is the size of the image layer 200, and d1 is the size of the suspended image S. Optionally, the magnification M can range from -100 to -50, -50 to -20, -20 to -10, -10 to -2, or -2 to -1. The negative sign indicates that the suspended image S is an inverted image. By appropriately setting the magnification, the tiny information in the image layer 200 can be magnified into a clearly visible suspended image S, meeting the visual presentation requirements of brand logos and other graphics on vehicle windows. Furthermore, different magnification values can adapt to different sizes of image layers 200 and different observation needs, improving the flexibility of imaging.
[0062] In some embodiments, the first light-transmitting element 100 and / or the second light-transmitting element 400 may be configured to be thermally or chemically strengthened, which helps to improve the structural strength of the first light-transmitting element 100 and / or the second light-transmitting element 400. The strengthened light-transmitting element has higher impact and scratch resistance, and can effectively resist damage such as external collisions and stone impacts, thereby improving the overall structural stability and service life of the light-transmitting element 10, while also meeting the safety performance requirements of vehicle glass.
[0063] In some embodiments, the first light-transmitting body 100 and / or the second light-transmitting body 400 can be configured as a flat surface or a curved surface, which helps to improve the adaptability and application scenario diversity of the first light-transmitting body 100 and / or the second light-transmitting body 400, and can match the glass shape requirements of different parts of the vehicle, such as curved windshields, flat side window glass, etc., so that the light-transmitting component 10 of this application can be widely used in various parts of the vehicle.
[0064] In some embodiments, the thickness of the first light-transmitting element 100 and / or the second light-transmitting element 400 can be configured to be 0.2mm-6mm. Optionally, the thickness of the first light-transmitting element 100 and / or the second light-transmitting element 400 can be configured to be 0.5mm-4mm, and optionally, the thickness of the first light-transmitting element 100 and / or the second light-transmitting element 400 can be configured to be 1mm-3mm. Thus, a reasonable thickness setting can reduce the overall weight of the light-transmitting element 10 while ensuring the strength and protective performance of the glass structure, conforming to the design trend of vehicle lightweighting. At the same time, a moderate thickness can also reduce light refraction loss and ensure imaging effect.
[0065] Please see Figures 1 to 5In some embodiments, the graphic layer 200 is disposed on the side of the substrate layer 310 facing away from the lens array layer 320. The graphic layer 200, the substrate layer 310, and the lens array layer 320 form a combined film layer. An adhesive layer 700 is provided between any two of the first light-transmitting body 100, the second light-transmitting body 400, the aforementioned combined film layer, the dimming layer 500, and the light source layer 600. This helps to improve the stability of the structural connection. The design of the aforementioned combined film layer can simplify the assembly process of the light-transmitting component 10, integrate the graphic layer 200 and the optical film 300, and improve production efficiency. The adhesive layer 700 can ensure the tight fit between the layers, avoid the formation of air bubbles or gaps between layers, prevent stray light reflection between layers, ensure imaging effect, and improve the overall sealing and structural stability of the light-transmitting component 10.
[0066] Please see Figure 7 In some embodiments, the graphic layer 200 is disposed on the inner surface of the first light-transmitting body 100, and the graphic layer 200 and the first light-transmitting body 100 form a combined glass structure. In this embodiment, an adhesive layer 700 is provided between any two of the aforementioned combined glass structure, the second light-transmitting body 400, the optical film 300, the dimming layer 500, and the light source layer 600.
[0067] Specifically, according to the above embodiments of this application, the configuration of the adhesive layer 700 between each structure can be adjusted for different positions of the graphic layer 200, which helps to improve the connection stability between each structure and adapt to different structural design requirements.
[0068] In some embodiments, the adhesive layer 700 can be PVB (Polyvinyl Butyral), EVA (Ethylene Vinyl Acetate Copolymer), or OCA (Optically Clear Adhesive), etc. These optical adhesive materials have the characteristics of high light transmittance, high bonding strength, and good weather resistance. They can reduce light transmission loss and improve imaging effect while ensuring a tight connection between the layers. They also have good resistance to high and low temperatures and anti-aging properties, making them suitable for the complex use environment of vehicles.
[0069] In some embodiments, one of the plurality of adhesive layers 700, positioned near the first light-transmitting body 100, has a preset transmittance and a preset haze. The preset transmittance ranges from greater than or equal to 85%, and the preset haze ranges from less than or equal to 1%. Alternatively, the preset haze ranges from less than or equal to 0.4%. This helps to reduce light obstruction and scattering, ensuring the propagation efficiency of incident and imaging light, further improving the presentation effect of the suspended image S. At the same time, the low-haze adhesive layer 700 can ensure the overall light transmittance of the glass, while also maintaining the clarity of the driving view.
[0070] In some embodiments, both the image layer 200 and the lens array layer 320 include a dielectric filling material, which helps to improve the connection stability between the image layer 200 and the lens array layer 320 and the other layer structures, and avoids problems such as detachment and cracking of the image layer 200 and the lens array layer 320. At the same time, the dielectric filling material is made of a high-transmittance optical material, which can reduce light loss, ensure imaging effect, and also improve the weather resistance of the image layer 200 and the lens array layer 320, adapting to the complex use environment of vehicles.
[0071] In some embodiments, the surfaces of the image layer 200 and the lens array layer 320 are coated with a protective film layer, which helps to improve the protection of the image layer 200 and the lens array layer 320, ensure the pixel accuracy of the image layer 200 and the structural integrity of the lens array layer 320, and provide a foundation for clear levitation imaging.
[0072] In some embodiments, the thickness of the substrate layer 310 can be configured as 10μm-20μm, 20μm-50μm, 50μm-60μm, 60-100μm, 100μm-200μm, 200-300μm, 300μm-500μm or ≥500μm. Different thickness values can adapt to different structural design requirements, ensure the stability of the substrate layer 310 in supporting the lens array layer 320, and at the same time take into account the overall thinness of the light-transmitting element 10, avoiding problems such as increased glass weight and excessive light loss caused by excessive thickness of the substrate layer 310.
[0073] In some embodiments, the light-transmitting element 10 is further provided with a light strip (not shown), which can be disposed on the circumferential edge of the first light-transmitting body 100 and / or the second light-transmitting body 400. The light strip is used to emit light and guide it into the interior of the light-transmitting element 10, thereby illuminating and forming the aforementioned floating image S. The addition of the light strip can provide an auxiliary light source for floating imaging, further improving the brightness and recognizability of the image. At the same time, the light strip can realize color light effect switching, which can cooperate with the floating image S to present a variety of visual effects, enhancing the appearance and technological feel of the vehicle. In addition, the light strip is set on the circumferential edge of the glass, so it will not interfere with the driver's field of vision, taking into account both decoration and practicality.
[0074] In some embodiments, the light source layer 600 has a preset brightness L. The value range of the preset brightness L can be configured as L≥1 nits, L≥2 nits, L≥5 nits, L≥10 nits, L≥20 nits, L≥50 nits, L≥100 nits, L≥200 nits, L≥500 nits, L≥1000 nits, L≥2000 nits or L≥3000 nits. This ensures that the light source layer 600 has sufficient light intensity to meet the supplementary lighting needs in different low-light environments. At the same time, the brightness can be adjusted according to the actual scene to avoid glare caused by excessive light and ensure the comfort of the imaging effect.
[0075] In some embodiments, the dimming layer 500 may be, but is not limited to, PDLC (Polymer Dispersed Liquid Crystal), EC (Electrochromic), SPD (Suspended Particle Device), or LC (Liquid Crystal). These dimming materials all have good electroluminescence dimming performance, enabling rapid and reversible adjustment of light transmittance. They also have good weather resistance, long service life, and adaptability to the complex use environment of vehicles. Different dimming materials can be adapted to different product positioning and usage requirements, improving the flexibility of product selection.
[0076] It is worth noting that the first light-transmitting body 100 and the second light-transmitting body 400 of the light-transmitting component 10 provided in this application can also be replaced with other counterpart components, such as vehicle trim and the surface protective layer covering the trim. This allows for the realization of the floating pattern effect of other products, and is not limited to the light-transmitting component 10 of this application, thus improving applicability. For example, the first light-transmitting body 100 can be replaced with the aforementioned surface protective layer of the trim, and the second light-transmitting body 400 can be replaced with the aforementioned trim. This enables the realization of the floating pattern effect of the trim on one side of its surface protective layer, allowing the floating imaging technology of this application to be widely applied to various vehicle trims, such as center console trim and door trim, further expanding the application scenarios of the technology.
[0077] According to another aspect of this application, this application also provides a vehicle that may include the aforementioned light-transmitting component 10. Applying the light-transmitting component 10 to a vehicle can replace traditional ink-printed or sticker-based trademarks, achieving a three-dimensional, floating presentation of the brand logo. This significantly enhances the vehicle's aesthetics and technological appeal, improves brand recognition, and the structural design of the light-transmitting component 10 effectively protects the trademark, avoiding the problem of easy damage associated with traditional methods and extending the lifespan of vehicle parts. Furthermore, the light-adjusting and supplemental lighting functions of the light-transmitting component 10 allow the floating trademark to be adjusted according to actual needs, balancing practicality and aesthetics, and meeting the design and usage requirements of high-end vehicles.
