Description

Technical Field

[0001] This disclosure relates to the field of optical technology, and more specifically, to an optical trim for a vehicle and the vehicle itself. Background Technology

[0002] With the rapid development of the automotive industry, vehicle interior design and functionality are constantly innovating. As an important component of vehicle interiors, optical trim is also undergoing continuous upgrades in design and function. In particular, optical trim such as roll-up starry sky curtains have become important elements in enhancing the interior atmosphere and user experience of vehicles.

[0003] Currently, optical components in vehicle interiors mainly include light-guiding optical components and light-emitting optical components. Light-guiding optical components typically consist of a light-guiding layer and a light source. The light emitted from the light source propagates within the light-guiding layer and its propagation direction is altered by specific optical structures, thus presenting a preset pattern on the light-emitting surface. Light-emitting optical components, on the other hand, typically use self-emissive materials or devices as a direct light source, eliminating the need for a separate light-guiding layer for light transmission. Common light-emitting optical components include components employing technologies such as LED arrays, OLED panels, or EL (electroluminescent) films.

[0004] However, existing optical components still present several technical challenges. First, in existing UFL (Ultra-thin Light Guide Film) starry sky designs, the light box is typically fixed to a track. This structure results in low light guiding efficiency, high power consumption, and poor heat dissipation. Furthermore, the display pattern of the UFL starry sky needs to be preset, and different patterns cannot be controlled individually, leading to a limited display effect and a lack of interactive functionality. Second, existing COB (Chip On Board) starry sky designs suffer from complex manufacturing processes, uneven color mixing, and color distortion caused by micro-perforation obstruction. Moreover, each perforation (0.8~1.5mm in diameter) requires the integration of several light-emitting chips (approximately 0.2*0.2mm each), resulting in complex manufacturing processes and high production costs.

[0005] Therefore, there is an urgent need for a new type of optical trim that can be used in vehicles or other transportation vehicles to solve the technical problems existing in the prior art, improve the performance of the interior trim, and meet the diverse needs of users.

[0043] In the existing technology, UFL starry sky roofs in vehicle interiors have technical problems such as low light guiding efficiency, high power consumption, poor heat dissipation, and uneven brightness distribution; COB starry sky roofs have technical problems such as complex manufacturing process, high manufacturing cost, uneven color mixing, and micro-pore obstruction leading to different colors.

[0044] As described below, some exemplary embodiments of this disclosure provide a novel optical element and its application in vehicles to address at least some of the aforementioned technical problems.

[0045] refer to Figures 1 to 4 This disclosure provides a schematic diagram of the structure of an optical trim 100 for a vehicle, according to one embodiment. The optical trim 100 includes a carrier layer 101, a light-emitting unit 102, and a light-guiding layer 103.

[0046] The light-emitting unit 102 includes a front-emitting light source and a side-emitting light source. The front-emitting light source and the side-emitting light source can be multi-faceted light sources, that is, front-emitting and side-emitting light can be achieved by the same light source; or they can be single-faced light sources, where front-emitting and side-emitting light are achieved by different light sources. The light-emitting unit 102 is deployed on the support layer 101.

[0047] A front-emitting / side-emitting light source can be an RGB LED or RGBWLED chip that provides front / side emission, or it can be a monochrome LED chip (e.g., blue, green, and / or red). Based on size, LEDs can be categorized as Mini LEDs, Micro LEDs, and conventional LEDs (typically in the millimeter range). Monochrome LED chips can achieve light mixing through the use of fluorescent materials; for example, phosphors / adhesives can be attached to the chip.

[0048] In some examples, the arrangement of the front-emitting and side-emitting light sources in the light-emitting unit 102 can be such that the side-emitting light sources are arranged on the side and the front-emitting light sources are arranged on the front. In some examples, the arrangement of the front-emitting and side-emitting light sources in the light-emitting unit 102 can be a random combination of the front-emitting and side-emitting light sources. The arrangement of the light sources can be adjusted according to actual needs. The main purpose of the side-emitting light sources is to provide light for guiding light to the light guide layer 103. In some examples, the height of the side-emitting light sources is flush with or slightly lower than the light-incident surface of the light guide film, which is beneficial to improving luminous efficiency. In some examples, the light-emitting unit 102 can be a single-layer structure or a multi-layer laminated structure.

[0049] In some examples, the carrier layer 101 serves as the substrate for supplying power to the light source and for supplying the light source patch. It can be made of PI, ABS, PC / PMMA, PET, or any co-extruded material combining these materials. The carrier layer 101 can be transparent, translucent, or opaque, and its thickness can range from 0.01 mm to 1.0 mm. Considering its flexibility and rollability, a thickness of 0.1 mm to 0.3 mm is preferred.

[0050] In some examples, circuitry is printed on the carrier layer 101 to provide power and communication for the light source. The circuitry can be printed on both sides or one side as needed, or it can be printed in the middle of different substrates by co-extrusion to achieve multi-layer printing and provide stable voltage and signal transmission.

[0051] In some examples, light sources of different types and heights can be arranged on the carrier layer 101 to present a three-dimensional lighting effect when lit, thus satisfying the spatial layering required for the displayed pattern.

[0052] A light guide layer 103 is deployed on a carrier layer 101 (it can be directly connected to the carrier layer, or it can be deployed on other layers or components on the carrier layer 101). Furthermore, the light guide layer 103 has a light-guiding optical microstructure 1032. Light emitted laterally from a side-emitting light source passes through the optical microstructure 1032 of the light guide layer 103 to cause the optical decorative element 100 to exhibit a first display effect, while light emitted directly from a front-emitting light source causes the optical decorative element 100 to exhibit a second display effect. Users can control the optical decorative element to exhibit only the first display effect, only the second display effect, or a combination of both effects according to the actual scene.

[0053] In some examples, the light guide layer 103 is a flexible, ultra-thin, light-guiding, and rollable material. The material can be PC, PMMA, PET, ABS, or any combination of these materials in a co-extruded form. It allows for effective light transmission within the material, and the thickness can range from 0.01mm to 1.0mm, preferably 0.1mm to 0.3mm, providing good flexibility and rollability. Furthermore, the light guide layer 103 can be a single-layer structure or a multi-layer structure formed by lamination and stacking. The light transmittance of the light guide layer 103 can be any value between 0.1% and 99.9%, which can be adjusted according to application requirements.

[0054] In some examples, the optical microstructure 1032 on the light guide layer 103 includes optical micro / nanostructures, which can be in the form of light spots, lines, or patterns. The optical microstructure 1032 can include several optical micro / nanostructures with different groove depths and groove shapes. When light emitted from the light source enters the light guide layer, the propagation path of the light will be changed by the optical micro / nanostructures. The optical micro / nanostructures can reflect, refract, or diffract the light, thereby making the light present the desired effect. The specific structure, position, and number of the optical microstructures can be adjusted and designed as needed.

[0055] In some examples, the light guide layer 103 is provided with a light-transmitting portion 1034, through which light emitted from a positively emitting light source passes and is emitted outward, allowing the optical component 100 to exhibit a second display effect. The light-transmitting portion 1034 can be a light-transmitting opening of different types, such as a light-transmitting hole, or a light-transmitting area formed by other light-transmitting materials deployed on the light guide layer 103. In some examples, the light source exposed by the light-transmitting portion 1034 can be a multi-faceted light source, wherein the light emitted from the side of the light source can illuminate the optical microstructure (e.g., micro-nano light spots) of the light guide layer.

[0056] In some examples, the optical trim 100 also includes a roll-up member 104 connected to the carrier layer 101 for rolling up and unrolling the optical trim 100. (Reference) Figure 15 and 16 A schematic diagram of the structure of the winding member 104 of the optical trim 100 is shown, wherein, Figure 15 This is a schematic diagram of the external structure. Figure 16 This is a partial sectional view. For example... Figure 15 and 16 As shown, in some examples, the winding member 104 has an opening 1042 for a cable to pass through to power the light-emitting unit 102.

[0057] In some examples, the light-emitting unit 102 includes a flexible printed circuit board (FPC) 1022 and a light source 1024 deployed thereon. The light source 1024 can be an LED chip soldered onto the flexible printed circuit board, i.e., an LED light-emitting module based on POB (Package on Board) technology. The LED chip soldered onto the flexible printed circuit board can be a single-sided emitting LED chip or a multi-sided emitting LED chip. In other examples, the light-emitting unit 102 can be obtained based on COB (Chip on Board) technology. In still other examples, the light source of the light-emitting unit 102 can be an OLED, miniLED, microLED, or other type of light-emitting chip. For an OLED light source, each OLED pixel is an independent light-emitting point. Each independent light-emitting point can be controlled to emit light independently by a drive signal provided by a control device. Multiple light-emitting points can emit light simultaneously, separately, or alternately to provide light to the light guide layer. For a miniLED or microLED light source, each LED chip is an independent light-emitting point. Each LED chip can be controlled to emit light independently by a drive signal provided by a control device. Multiple LED chips can emit light simultaneously, individually, or alternately to provide light to the light guide layer.

[0058] In some examples, the carrier layer 101 can be a flexible circuit board, and the light-emitting unit 102 is a light source. The light source is directly deployed on the carrier layer, i.e., the flexible circuit board. In some examples, the flexible circuit board is a transparent or semi-transparent circuit board, and a front-emitting light source is deployed on the first side of the flexible circuit board. The light emitted from the front is transmitted through the flexible circuit board into the vehicle's interior, enabling the optical trim 100 to present a second display effect. The light guide layer 103 is deployed on the second side of the flexible circuit board, and a side-emitting light source is deployed on the flexible circuit board and located on the side of the light guide layer 103. The light emitted from the side of the side-emitting light source is guided by the optical microstructure 1032, enabling the optical trim 100 to present the first display effect.

[0059] In some examples, a plurality of light-transmitting holes are deployed on the flexible circuit board, and the plurality of light-transmitting holes correspond to the light-emitting ends of a plurality of optical microstructures 1032 respectively; a forward-emitting light source is deployed on the second side of the flexible circuit board, and the light emitted from it shines directly into the vehicle, so that the optical trim 100 presents a second display effect; a light guide layer 103 is deployed on the first side of the flexible circuit board, and a side-emitting light source is deployed on the flexible circuit board and located on the side of the light guide layer 103. The light emitted from the side of the side-emitting light source enters the vehicle through the optical microstructures 1032 and the light-transmitting holes, so that the optical trim 100 presents a first display effect.

[0060] In some examples, such as Figure 1As shown in Figures 2(a) and 2(b), the LED beads in the light-emitting unit 102 are arranged in a grid. Figure 2(b) is a schematic diagram of the hierarchical structure of the optical component 100 shown in Figure 2(a). The optical component 100 consists of a carrier layer 101, a light-emitting unit 102, and a light guide layer 103. The light-emitting unit 102 includes a flexible circuit board 1022 and a light source 1024 deployed thereon. The light source 1024 can be LED beads. In some examples, the LED beads are multi-faceted LED beads, capable of both frontal and side-emitting light. The light emitted from the frontal LED beads gives the optical component 100 a first display effect, which can display patterns, characters, numbers, etc. Furthermore, by controlling the LED beads, variations in the first display effect can be achieved; for example, controlling... Figure 1 The LED beads within the black frame L emit light sequentially from the front, creating a shooting star effect. Light emitted from the side of the LED beads can be guided by the optical microstructure in the light guide layer (light guide film) 103, allowing the optical decorative element 100 to display a second effect, such as a starry sky. Simultaneous front and side emission of the LED beads allows the optical decorative element 100 to exhibit a superposition of the first and second display effects, such as shooting stars under a starry sky.

[0061] As shown in Figure 3(a), Figure 3(b) and Figure 4 As shown, in some examples, the light-emitting unit 102 includes an LED strip, a flexible circuit board, and LED beads soldered onto the flexible circuit board. The LED strip is deployed on both sides of the light guide layer 103 and mounted on the carrier layer 101. It is a side-emitting light source, and the light emitted from its side is guided by the optical microstructure 1032 in the light guide layer 103, so that the optical decorative element 100 presents a second display effect. The LED beads soldered onto the flexible circuit board are front-emitting light sources, and the light emitted from their front direction makes the optical decorative element 100 present a first display effect.

[0062] In some examples, the light-emitting unit 102 is a flexible LED light panel. Side-emitting LED strips are designed on both sides of the LED light panel, and a front-emitting (direct-light) LED matrix is ​​arranged in the middle. The light guide layer 103 can be a UFL light guide film, on which micro-nano imprinted optical structures (light-guiding optical microstructures) are arranged. The light emitted from the side-emitting LED strips is guided by the optical microstructures on the UFL light guide film, causing its light-emitting end to appear as a light spot. Optionally, several light-transmitting openings are deployed on the UFL light guide film, and the LED matrix is ​​embedded in the carrier layer 101 corresponding to the positions of the light-transmitting openings. In some examples, the LED matrix is ​​a multi-faceted light source, which can emit both front and side light through the light-transmitting openings. The side-emitted light can illuminate the optical microstructures on the UFL light guide film; in other words, the LED matrix can also serve as the light source for the UFL light guide film.

[0063] In some examples, the carrier layer 101 includes a flexible circuit board, and the light-emitting unit 102 includes multiple LED beads soldered onto the flexible circuit board. In some examples, the LED beads can be controlled independently, in combination, or in zones; they can be lit synchronously, gradually, or in combination, and can be combined arbitrarily. For example, the LED beads in the black box L1 in Figure 3(b) are used to achieve a meteor effect. Each LED bead on the meteor trajectory can be controlled independently and lit gradually, while LED beads outside the meteor trajectory can be controlled to turn off synchronously. Another example is that the LED beads can be grouped and controlled based on constellation patterns. Yet another example is that, referring to Figure 3(b), the LED beads can be grouped and controlled by region. For example, the LED beads can be divided into groups G1-G7 as shown in the figure, and the LEDs in G1-G7 can be lit sequentially to achieve a dynamic lighting effect, enriching the product's display effect. Yet another example is that navigation information can be displayed; specifically, in-vehicle navigation information can be displayed in real time during vehicle operation for rear passengers to view. For example, it can display characters, patterns, and other information. Specifically, when the vehicle is in welcome mode, it can display "WELCOME"; when the vehicle is in birthday party mode, it can display patterns such as "cake" and "fireworks"; when the vehicle is in game mode, it can display game control interfaces or related patterns, such as "Snake" and "Tetris"; when the vehicle is in interactive mode, it can receive projections to display the corresponding screen of a mobile phone; when the vehicle is in rest mode, it can control the changes in lighting to create scenes such as night or sunset to achieve a sleep-inducing effect.

[0064] In some examples, the light guide layer (e.g., UFL light guide film) can be embedded with the flexible base film of the flexible circuit board and bonded together by an encapsulation process to form a composite. Furthermore, the first surface (back side) of the composite can be covered with a sunshade layer, and the second surface (front side) can be covered with a decorative layer with micropores (also known as a fabric layer), such as leather, fabric, etc.

[0065] In some examples, the combination of UFL light guide film, side-emitting LED strips, and front-emitting LED matrix can achieve the following lighting effects: the side-emitting LED strips emit light, which makes the UFL light guide film present a starry sky effect; the front-emitting LED matrix and the side-emitting LED strips emit light together, and the front-emitting LED matrix can achieve the effect of a shooting star. Together with the side-emitting LED strips and UFL light guide film, they can achieve the effect of a shooting star streaking across the starry sky.

[0066] In some examples, the light source in the light-emitting unit 102 may be only an LED strip mounted on the carrier layer 101. The LED strip includes front-emitting LED beads and side-emitting LED beads. The front-emitting LED beads and the side-emitting LED beads can be the same multi-sided emitting LED bead or different single-sided emitting LED beads. Figure 5(a) shows a schematic diagram of the structure of a multi-sided emitting LED bead 502. Figure 5(b) shows a schematic diagram of the structure of a single-sided emitting LED bead 504. The LED beads can be arranged in an array, a discrete arrangement, or an alternating arrangement. The LED beads can be alternating with the optical microstructure 1032 on the light guide layer 103, and the front-emitting LED beads and the side-emitting LED beads can be alternating.

[0067] In some examples, such as Figure 6 and Figure 7 As shown, a front-emitting light source is deployed in the central area of ​​the carrier layer 101. This front-emitting light source can be an LED strip bonded to the carrier layer or an LED matrix soldered to a flexible circuit board. Side-emitting LED strips are deployed on both sides of the carrier layer 101. The LED matrix deployed in the central area of ​​the carrier layer forms a light-emitting screen, enabling effects such as individual LED illumination, shooting stars, and various customized patterns. The central deployment of the LED matrix in the carrier layer facilitates viewing and interactive operation for users in different positions on the vehicle. The light guide layer 103 can be a UFL light guide film, which has an optical structure with micro-nano imprinting. The LED beads in the side-emitting LED strips are aligned with the light-inlet end of the optical microstructure in the UFL light guide film. The light emitted by the side-emitting LED strips, guided by the optical microstructure, can achieve a starry sky effect. The LED matrix in the central area can be superimposed on the actual starry sky to achieve a shooting star effect.

[0068] In some examples, such as Figures 8 to 12 As shown, a flexible circuit board 1022 is deployed in the first region of the carrier layer 101, and a light guide layer 103 is deployed in the second region of the carrier layer 101. In some examples, the first region of the carrier layer 101 is a central region, and the second region of the carrier layer 101 is a side region. The flexible circuit board 1022 being deployed in the central region of the carrier layer facilitates viewing and interactive operation by users at different positions on the vehicle. The flexible circuit board 1022 and the LED beads soldered thereon form a flexible LED light panel. The LED light panel, deployed in the middle of the carrier layer, forms an LED screen, which can be used to achieve effects such as individual LED illumination, shooting stars, and various customized patterns. The light guide layer 103 can be a UFL light guide film, on which an optical structure with micro-nano imprinting is disposed.

[0069] In some examples, such as Figures 8 to 12As shown, a front-emitting LED is soldered to the center of the flexible circuit board 1022, and side-emitting LEDs are soldered to its sides. A row of side-emitting LEDs can be soldered to each side of the flexible circuit board 1022, as shown below. Figure 8 , 9 As shown in Figure 10; alternatively, only one side-emitting LED bead can be soldered, such as... Figure 11 and 12 As shown, the light-inlet ends of the side-emitting LED beads and the UFL light guide film's micro-nano imprinted optical structure are deployed accordingly; the side-emitting LED beads and the light guide film can be used to achieve starry sky light effects; the front-emitting LED beads can be used to achieve dynamic patterns, numbers, and other display effects.

[0070] refer to Figure 13 In some examples, the optical component 100 includes a sunshade layer 106 and a finishing layer (fabric layer) 109. The sunshade layer 106 is positioned above the carrier layer 101 to block light; the finishing layer 109 is positioned below the carrier layer 101 to shield the internal structure of the optical component 100. In some examples, the optical component 100 also includes an adhesive layer 108. The figure only shows one adhesive layer as an example, but all layers can be bonded together by adhesive layers.

[0071] In some examples, the adhesive layer can be in the form of glue, adhesive patches, or adhesive films. In some examples, the adhesive layer can be OCA adhesive (Optically Clear Adhesive), which has extremely high light transmittance, low haze, excellent bond strength, long-term weather resistance, and can eliminate interface reflections. In some examples, the adhesive layer can be a foamed material, such as foam. The elastic structure of foamed materials provides cushioning protection for the internal light guide layer and light-emitting unit, resisting repeated winding stress, while also achieving uniform bonding of multi-layer materials through gap filling capabilities. Since the light source of the light-emitting unit has a certain height, the adhesive layer can be a flexible glue or foam bonded between the light-emitting layer and other layers to fill the gaps. The filling height should be higher than the height of the light source to improve the flatness of the surface after lamination and avoid step problems after lamination.

[0072] refer to Figure 14 In some examples, the decorative layer 109 can be a material such as leather or fabric with holes 1091. In some examples, the fabric layer can be a translucent material, such as translucent leather, fabric, or film.

[0073] In some examples, the shading layer 106 can be a shading base fabric, a shading TPU material, a coating, or an ink material. In some examples, the shading layer 106 can be a micro-nano high-reflectivity coating or a high-reflectivity polymer material, disposed on the back (above) of the supporting layer 101, to reflect sunlight and provide shading.

[0074] In some examples, the optical element 100 also includes an interaction layer 107, which may include a spatial sensor (TOF, Time of Flight) 105 for recognizing human posture and gestures, thereby enabling direct interaction between the optical element and the human. The spatial sensor may be deployed on the support layer 101, near the linkage of the retraction component, forming a spatial sensing area during operation to detect human actions.

[0075] In some examples, the interaction layer 107 can be positioned between the layers of the optical trim 100, such as between the trim layer (also known as the fabric layer) and the light guide layer, or between the light guide layer and the carrier layer, or between the carrier layer and the sunshade layer. The interaction layer can be a spatial detection module, or a standalone sensor module, which may include a camera and / or a millimeter-wave sensor. In some examples, the sensor module operates as follows: the sensor emits sensing signals such as infrared or ultrasonic waves, which are reflected back to the sensor upon encountering a human body. The control unit within the sensor, or a standalone control unit communicatively connected to the sensor, processes the reflected signals using software algorithms to recognize the user's posture and gestures, thereby executing the user's interactive commands.

[0076] In some examples, the sensor module may include a capacitive pressure sensor, a resistive pressure sensor, or a capacitive-resistive integrated pressure sensor, which can not only be used to achieve proximity sensing, but also detect the pressure value it is subjected to, thereby enabling bipolar control and avoiding malfunctions caused by accidental touches.

[0077] Another embodiment of this disclosure provides a means of transportation (not shown), including: a body; and the aforementioned optical trim deployed on the body. The optical trim in this embodiment is similar to the implementation of the aforementioned optical trim 100, and therefore will not be described again. The means of transportation can be a vehicle, ship, airplane, etc., and this disclosure does not limit this.

[0078] In some examples, the vehicle also includes a control device deployed on the body and controlled and coupled to the optical trim 100 for controlling the deployment and retraction of the optical trim 100, as well as controlling the operating modes of the optical trim 100, such as a welcoming mode, a rest mode, and / or an interactive mode.

[0079] The optical trim 100, deployed on the vehicle body, can perform various operating modes to meet diverse user needs. For example, a welcome mode: it creates a lighting effect resembling shooting stars and a starry sky. Another example is a shooting star mode: it creates a shooting star effect, suitable for birthday parties, prayers, and other similar occasions. Yet another example is a rest mode: it creates a slowly changing starry sky effect with varying color temperatures. And yet another example is an interactive mode: it can be used to display navigation information, game information, or for screen projection and interactive interaction with mobile phones (e.g., playing gesture-sensitive games like Fruit Ninja).

[0080] In some examples, the optical element 100 can be linked with audio equipment on vehicles to create a unified, immersive experience by changing sound effects according to the needs of the scene. For example, in rest mode, the optical element (curtain) can be controlled to display a starry sky effect, and the audio equipment can be controlled to play calming, deep music, which is more conducive to the user's rest, such as helping the user enter a meditative state. For example, in interactive mode, the light and sound effects can be changed in conjunction with the user's posture and gestures. For example, when the user moves the curtain, the curtain can be controlled to display a nebula-like light effect, and the audio equipment can be controlled to emit a sound of starry disturbance. In addition, the audio equipment can be controlled to issue different sound commands in conjunction with different gestures.

[0081] The optical trim for vehicles disclosed herein employs a light-emitting mechanism that combines active and passive light-emitting mechanisms. The light guide layer, in conjunction with a side-emitting light source, enables the optical trim to exhibit a first display effect, while a front-emitting light source enables it to exhibit a variety of second display effects. Furthermore, the first and second display effects can be superimposed to meet diverse user needs. This optical trim offers advantages such as high light-guiding efficiency, uniform light emission, simple structure, low cost, easy heat dissipation and low power consumption, diverse patterns, and real-time user interaction.
