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 (each approximately 0.2*0.2mm), resulting in complex manufacturing processes and high costs.

[0005] Therefore, there is an urgent need for a new type of optical trim to solve the technical problems existing in the current technology, improve the performance of the interior of vehicles, and meet the diverse needs of users. Summary of the Invention

[0034] 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.

[0035] 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.

[0036] refer to Figures 1 to 4 One embodiment of this disclosure provides an optical trim 100 for a vehicle. Figure 1 Here is a simplified structural diagram of the optical trim 100. Figure 2 This is a three-dimensional structural diagram of the optical trim 100. Figure 3 This is a schematic diagram of the roll-up structure of the optical trim 100. Figure 4 This is a schematic diagram showing the contact between the light source of the optical accessory 100 and the scroll.

[0037] As shown in the figure, the optical component 100 includes a carrier layer 101 (carrier film), a light guide layer 102 (light guide film), a light source 103, and a winding component 104 (roller and related components). The light guide layer 102 is disposed on the carrier layer 101, and a light-guiding optical microstructure (e.g., a micrometer- or nanometer-scale microstructure) is disposed on the light guide layer 102. The light-inlet end of the optical microstructure is disposed on at least one side of the light guide layer 102. Figure 1 The center can be either the left or right side, or one of the side edges, or the bottom edge. The light source 103, corresponding to the light-gathering end of the optical microstructure, is deployed on at least one side of the support layer. Figure 1 The center can be either the left or right side, or one of the side edges, or the bottom edge. The light emitted by the light source 103 enters the interior of the optical microstructure through the light-inlet end, causing its light-emitting area to emit light. The winding component 104 is coupled to the carrier layer 101, and drives the light guide layer 102 and the light source 103 to move through the carrier layer 101, thereby realizing the unfolding or winding of the optical ornament 100.

[0038] In some examples, the light guide layer 102 is a flexible light guide film, for example, it can be a UFL (Ultra-thin Light Guide Film), on which optical structures with micro-nano imprints (a light-guiding optical microstructure) can be deployed, and light from the light source 103 deployed on its side or bottom edge can be guided to make its corresponding micro-nano light spot emit light.

[0039] In some examples, light source 103 can be an LED lamp. LED lamps significantly reduce power consumption compared to traditional light boxes (typically saving 60%-80% of electrical energy). Furthermore, as a cold light source, LEDs generate very little heat, which helps reduce heat dissipation costs. In some examples, light source 103 can be an OLED, mini LED, micro LED, or other types of light source. 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 film. For a mini LED light source or a flexible micro LED 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, separately, or alternately to provide light to the light guide film.

[0040] In some examples, the light source 103 can be an LED array. In some examples, the light source 103 can be uniformly deployed on the left or right side of the carrier film 101, or symmetrically deployed on both sides of the carrier film 101. The array deployment of the light source is beneficial to improving the brightness and display uniformity of the light spot. In some examples, the light source 103 can be deployed parallel to the winding direction of the optical element 100. In other examples, the light source 103 can be deployed at an angle to the winding direction of the optical element 100. In some examples, some light sources 103 are deployed parallel to the winding direction of the optical element 100 (i.e., some light sources 103 are not deployed at an angle to the winding direction of the optical element 100), and some light sources 103 are deployed at an angle to the winding direction of the optical element 100. Furthermore, the angled light sources can be deployed at different angles.

[0041] refer to Figure 5-8 The light source 103 in the optical component 100 is deployed at an angle to the winding direction of the optical component 100. This can be a cross-deployment at 45° and 135°, or at other non-parallel angles. Angled deployment of at least some of the light sources 103 helps prevent the light source from being squeezed during winding, and also facilitates reducing the radius of curvature of the reel or the light source packaging strength, saving space and cost. For example, some LED lights are relatively long (e.g., 3.8mm). During reel winding, due to the small radius of curvature of the reel, the LED light may be squeezed, potentially causing damage. Therefore, a light source with a length within a preset range can be selected and deployed at an angle to the winding direction of the optical component 100, so that its projected length in the winding direction of the optical component 100 is less than a preset threshold.

[0042] In some examples, the sides of the light guide layer 102 are serrated, and the light source 103 is deployed along the serrated sides. The sides of the light guide layer 102 are designed with an irregular serrated shape, and the light source is deployed at a certain tilt angle (e.g., 45°) on the serrated edge of the light guide layer, forming a light guiding mechanism. This helps to reduce the contact area between the light source and the scroll (see reference). Figure 4 and Figure 8 This visually demonstrates different contact areas, improving system reliability. In other examples, the sides of the light guide layer 102 can be polygonal (e.g., trapezoidal, rhomboid) or curved (e.g., wavy, irregular curves), and the light source can be deployed at an angle to the winding direction of the optical component 100 along the polygonal or curved side. In some examples, the sides of the light guide layer 102 can also be partially serrated, partially polygonal, and / or partially curved, and can be flexibly designed according to product needs to achieve the technical effect of easy winding and light entering the light guide layer at the desired position and angle.

[0043] In some examples, the light source 103 may be deployed on only one edge of each serration of the light guide layer. In other examples, the light source 103 is deployed on both edges of each serration of the light guide layer. In some examples, the light-inlet end of the optical microstructure of the light guide layer 102 corresponds to at least two light sources 103 incident at different angles. The individual optical microstructure (light spot) is illuminated by light sources at different angles, which helps to avoid blocking the light guide path of two adjacent light spots in one direction, thereby improving the light guide uniformity of the product.

[0044] The light guide layer 102 of the optical component 100 can be one, two, or even more layers. Multi-layer light guide layers can achieve richer optical effects compared to single-layer light guide layers. In some examples, the light guide layer 102 includes a first light guide layer and a second light guide layer, with the optical microstructures of the first and second light guide layers arranged alternately. The first and second light guide layers can be bonded together using an adhesive process to avoid the adhesive affecting the light-emitting area of ​​the light guide layer. A micro / nano coating can be applied to the light-emitting area of ​​either the first or second light guide layer to prevent the adhesive from affecting the light-emitting area's light efficiency. A microporous foam layer or a base fabric layer can also be applied between the first and second light guide layers. The foam in the microporous foam layer can be used to bond the first and second light guide layers, and the micropores in the microporous foam layer prevent obscuring the optical microstructures of the light guide layer. The base fabric layer can also be used to bond the first and second light guide layers, and the base fabric layer can be perforated or made of a transparent material to avoid obscuring the optical microstructures of the light guide layer. It should be noted that the first and second light guide layers are not used to limit the number of light guide layers, but rather to describe the structural relationship between multiple light guide layers.

[0045] In some examples, light source 103 includes a first group of light sources and a second group of light sources. The light-inlet end of the optical microstructure of the first light guide layer corresponds to the first group of light sources, and the light-inlet end of the optical microstructure of the second light guide layer corresponds to the second group of light sources. The first group of light sources and the second group of light sources can be controlled synchronously or independently. Each light source in the first group of light sources / the second group of light sources can be controlled synchronously or independently to achieve different light effects.

[0046] In some examples, the first group of light sources and the second group of light sources are deployed on both sides of the light guide layer 102, that is, on both sides of the carrier layer 101. The first group of light sources is deployed on the first side (e.g., the left side) of the light guide layer 102, and the second group of light sources is deployed on the second side (e.g., the right side) of the light guide layer 102.

[0047] In some examples, the first group of light sources and the second group of light sources are staggered on the first side of the light guide layer 102, and / or the first group of light sources and the second group of light sources are staggered on the second side of the light guide layer 102. Even if the light source is deployed only on one side of the light guide layer 102, that is, only one side of the carrier layer 101, it can still supply the light source requirements of multiple light guide layers.

[0048] refer to Figure 9 The diagram illustrates a structural schematic of a light guide layer 102. The light guide layer 102 is a flexible light guide film, for example, it can be a UFL (Ultra-thin Light Guide Film). The UFL can have uniformly deployed optical structures with micro / nano imprints (light-guiding optical microstructures 1022). A UFL is a flexible thin film that utilizes precise microstructure optical design to efficiently convert point or line light sources into uniform surface light sources; its thickness can be less than 0.5 mm, possessing the characteristics of being ultra-thin, lightweight, and flexible, achieving high brightness and high uniformity backlighting effects within a very small space.

[0049] refer to Figure 10 This diagram illustrates a hierarchical structure of an optical trim 100, which includes a carrier layer 101 and a light guide layer 102. In some examples, the optical trim 100 includes a sunshade layer 105. The sunshade layer 105 is used for sun shading and can be implemented using sunshade fabric, sunshade coating, or PU adhesive. The sunshade layer 105 can be deployed on a first surface (upper surface, facing the top of the vehicle) of the carrier layer 101, and the light guide layer 102 can be deployed on a second surface (lower surface, facing the interior of the vehicle) of the carrier layer 101. In some examples, the optical trim 100 includes a sealing layer 106. The sealing layer 106 can be deployed on the second surface (lower surface) of the light guide layer 102. The sealing layer 106 can be a soft adhesive film used to seal the light source and the light guide layer, and to place the light source and the light guide layer in the same plane. In some examples, the optical trim 100 includes a fabric layer 107. The fabric layer 107 can be deployed on the second side (lower surface) of the sealing layer 106 and can be used to shield the internal structure of the optical component 100, providing an aesthetic effect. The fabric layer 107 can be a layer of leather, such as imitation suede or PU leather. Light-emitting holes are formed on the fabric layer 107, and the light-emitting holes are aligned with the micro-nano imprinted light spots / patterns on the light guide layer, allowing light to be emitted.

[0050] In some examples, the manufacturing process of the optical component 100 is as follows: a circuit is printed on the carrier layer 101; then, the light source 103 (side LED) is integrated on the carrier base film by surface mount technology (SMT); the light guide layer 102 (UFL light guide film) is attached to the carrier base film by spraying / dispensing adhesive; then, the sealing layer 106 (adhesive film) is applied to the laminated carrier layer 101 and light guide layer 102; finally, the sunshade layer 105 and the fabric layer 107 are attached respectively, so that the light outlet on the fabric layer 107 is aligned with the light spot.

[0051] refer to Figure 11 and 12 A schematic diagram of the structure of the winding member 104 of the optical trim 100 is shown, wherein, Figure 11 This is a schematic diagram of the external structure. Figure 12This is a partial cross-sectional view. The winding member 104 has an opening 1042 for the cable to pass through in order to power the light source 103 or control the on / off state of the light source.

[0052] In some examples, the optical element 100 also includes a space sensor (TOF, Time of Flight) deployed on the carrier layer 101, which can be used to recognize human posture and gestures, thereby enabling direct interaction between the optical element and the human.

[0053] Another embodiment of this disclosure provides a vehicle (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.

[0054] In some examples, the vehicle also includes a control unit deployed on the main 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 mode of the optical trim 100, such as controlling the optical trim 100 to operate in a welcoming mode, a rest mode, or an interactive mode. The control unit can be deployed independently on the optical trim 100, for example, it can be an electronic control unit (ECU) communicating with the vehicle's control center (e.g., a smart cockpit domain controller), or it can be integrated into other control units of the vehicle to achieve centralized control.

[0055] Optical components deployed on vehicles can operate in various modes to meet diverse user needs. For example, a welcoming mode provides a starry, illuminated effect. A rest mode allows for a gradually changing starry sky with varying color temperatures. An interactive mode can be used for screen projection and enables interaction through user gestures, such as in gesture-sensitive games like Fruit Ninja.

[0056] The optical trim for vehicles disclosed herein is an active light-emitting mechanism. Its light source can be deployed on the side and / or bottom edge of the support layer and can be rolled up. The optical trim has the advantages of high light guiding efficiency, uniform light emission, simple structure, easy heat dissipation and low power consumption, and has good commercial application prospects.
