Description

Technical Field

[0001] The present invention relates to the technical field of vehicle interior parts. More specifically, the present invention relates to a light-emitting rolling curtain device. Background Art

[0002] A starry sky roof is an interior part system that simulates the starry sky effect on the vehicle roof through lighting technology. It is commonly found in high-end luxury vehicles, combining technology and aesthetics to create a unique atmosphere for the driver and passengers.

[0003] In the current vehicle interior design, a relatively mature starry sky roof solution is achieved by inserting optical fibers (optical fibers coupled with LED light sources and related optical components). The limitation of this solution is that the light-transmitting fabric combined with the optical fibers cannot coexist with a retractable sunshade at the same time. Even in the aftermarket, there are some curtain cloth retraction solutions based on inserting optical fibers. However, due to the strength of the optical fibers themselves, the bonding strength of the inserted optical fibers often fails to pass the vehicle regulation-level tests. At the same time, since each optical fiber needs to be inserted manually, there are also certain limitations in terms of manufacturing cost and labor consumption, so this solution cannot be applied to general vehicles in large quantities.

[0004] Another solution is to apply the light guide film technology to a composite rolling curtain. Based on the side-lighting method, it cooperates with the light-emitting microstructures on the light guide film to achieve light emission, replacing the traditional optical fiber solution. In fact, in the current optical / light path design of vehicle interior atmosphere lights, usually through structural design, the relative positions of the light guide structure and the light source are fixed to ensure that the light emitted from the light source enters the light guide and propagates along the established light path, thus ensuring the light emission efficiency. And if the light-emitting body needs to move, the light source and the light guide need to move together. However, since the light source supporting the rolling curtain is still based on the traditional LED light source (or combined with a light condensing component), neither the material properties of the printed circuit board (PBC) (even a flexible printed circuit board (FPC) cannot meet the requirement of more than 20,000 retractions), nor the excessive space after retraction caused by the thickness of the light source can meet the requirement that the light source retracts together with the rolling curtain. Summary of the Invention

[0005] The object of the present invention is to provide an improved light-emitting rolling curtain device to overcome the above defects.

[0006] To this end, the present invention provides a light-emitting rolling curtain device, comprising: a guiding assembly; a light source fixed to the guiding assembly; and a light-shielding display assembly capable of moving along the guiding assembly to achieve unfolding or retracting, and comprising a light guide layer, wherein the light guide layer comprises a light incident end opposite to the light source and is provided with a plurality of light-emitting microstructures; wherein the light-emitting rolling curtain device is configured such that when the light-shielding display assembly moves along the guiding assembly, light emitted by the light source can enter the light guide layer through the light incident end, and after passing through the plurality of light-emitting microstructures, the propagation direction is changed and the light is emitted from one side surface of the light guide layer.

[0007] Therefore, the light-emitting rolling curtain device of the present invention is applicable to the situation where a flexible light guide member needs to be retracted with the curtain, but at the same time the light source cannot be retracted simultaneously due to space, thickness and its physical properties, such as the application of a light guide film in a retractable star ceiling. Specifically, the present invention provides a special coupling structure design between the light source and the light guide member for the light-emitting rolling curtain. This design can keep the light source fixed relative to the vehicle body when the light guide member moves relative to the vehicle body with the rolling curtain during the retracting movement, but maintain the positional relationship between the light incident end of the rolling curtain and the light-emitting end of the light source during the retracting process of the rolling curtain, so that the rolling curtain can be lit and emit light at any retracted position, that is, the light conduction efficiency is not affected by the retracting movement of the rolling curtain.

[0045] The elements in the drawings are shown for simplicity and clarity and are not necessarily drawn to exact scale and shape. It should be understood that the drawings are not only used for the explanation and illustration of the present invention, but also help to define the present invention when necessary. Detailed Embodiments

[0046] The implementation and use of the specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are only exemplary illustrations of specific ways of implementing and using the present invention and do not limit the scope of the present invention.

[0047] In this specification, when describing the structural positions, the directional expressions such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc. are not absolute but relative. For example, when the components are arranged as shown in the figures, these directional expressions are appropriate, but when the positions of the components in the figures change, these directional expressions should also change accordingly.

[0048] In this specification, unless otherwise clearly specified and limited, the terms "installation", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in this specification can be understood according to the specific circumstances.

[0049] In this specification and the accompanying drawings, the X direction represents the longitudinal direction of the vehicle (i.e., the front-to-back direction, which also corresponds to the driving direction of the vehicle), the Y direction represents the lateral direction of the vehicle (i.e., the left-right direction at a 90-degree angle to the driving direction), and the Z direction represents the vertical direction of the vehicle (i.e., the up-and-down direction perpendicular to the ground).

[0050] like Figure 1 and Figure 2 As shown, the luminous roller blind device according to the present invention is mostly used for the vehicle ceiling CL, for example, the luminous starry sky ceiling can be integrated into the sunshade roller blind of the skylight. More specifically, the light source assembly 100 can be fixed relative to the guide rail of the guide assembly of the roller blind, and the roller blind (i.e., the shading display assembly 200) is clamped by a mechanical structure so that it moves along the guide rail during the unfolding or retracting process, and the light emitted by the light source can always enter the composite hierarchical structure of the roller blind to present a starry sky effect.

[0051] Figure 3 is a schematic diagram of the reference plane arrangement of the luminous roller blind device according to the present invention, and the reference plane is used to define the relative position of the shading display component and the light source when the shading display component is directly or indirectly connected to the guide component. More specifically, as Figure 3As shown, in the light-emitting rolling curtain device of the present invention, there is a light source structure fixed relative to the vehicle body (such as the light source of the light source assembly 100 and / or the light condensing member 160 (which can also be a light condensing light guide), which will be described in detail in combination with specific embodiments below) and a flexible light-emitting mechanism (such as the light guide layer 220 of the light-shielding display assembly 200, which will be described in detail in combination with specific embodiments below). Among them, the light condensing member 160 has a first optical central axis AX1, and the light guide layer 220 has a second optical central axis AX2. By setting an appropriate lower virtual reference plane RP1 or upper virtual reference plane RP2, during the relative movement of the light condensing member 160 and the light guide layer 220, that is, during the process of the light-shielding display assembly 200 moving along the guide rail to achieve unfolding or retracting, the first optical central axis AX1 and the second optical central axis AX2 are always aligned, for example, they are always on the same curved surface according to the curved movement trajectory of the rolling curtain (the movement trajectory of the rolling curtain is usually curved relative to the X direction). Therefore, the light emitted from the light-emitting end of the light condensing member 160 can enter the light guide layer 220 from the light-incident end of the light guide layer 220 to present a light-emitting effect through the light guide layer 220. Preferably, the distance d between the light-emitting end of the light condensing member 160 and the light-incident end of the light guide layer 220 is usually set to be less than or equal to 5 mm.

[0052] As Figure 4As shown, according to an embodiment, the light source assembly 100 of the light-emitting rolling curtain device includes an upper housing 110, a lower housing 120, a heat dissipation framework 130, a light source 150, and a light condensing member 160. The upper housing 110 and the lower housing 120 are fixedly connected by fixing members such as screws, etc., and together with the heat dissipation framework 130, they jointly define a chamber 140 for arranging the light source 150. According to an implementation variant, the upper housing 110 can also be integrally formed with the lower housing 120. The light source includes, for example, a printed circuit board (PCB) 150 and a light-emitting component 151 disposed on the circuit board 150. The circuit board 150 can be fixedly connected to the upper housing 110 and / or the lower housing 120, and the surface of the circuit board 150 facing away from the light-emitting component 151 is attached to the heat dissipation framework 130. The light-emitting component 151 can be, but is not limited to, a light-emitting diode (LED), an organic light-emitting diode (OLED), a laser generator, etc. The light condensing member 160 has a flat structure with a thickness, for example, between 1 mm and 3 mm. It is clamped between the upper housing 110 and the lower housing 120 by the fixed connection of the upper housing 110 and the lower housing 120. More specifically, it is clamped between the lower protruding portion 111 of the upper housing 110 and the upper protruding portion 121 of the lower housing 120, and is in close contact with the bottom surface of the lower protruding portion 111 or the top surface of the upper protruding portion 121, so that the light incident end of the light condensing member 160 is aligned with the light-emitting component 151. The light condensing member 160 can be injection-molded or extruded from a resin material with excellent light guiding performance such as polymethyl methacrylate (PMMA) or polycarbonate (PC). To ensure that the light source assembly 100 stably and continuously provides light intensity and emits light along a predetermined light path, the light condensing member 160 needs to be adapted to the selected light source and corresponding micro-texture design or fold / reflection feature design is carried out.

[0053] As Figure 5As shown, according to one embodiment, the light-shielding display component 200 of the light-emitting rolling curtain device includes a composite rolling curtain structure formed by sequentially laminating a light-shielding layer 210, a light guide layer 220, and a light-transmitting layer 230. According to some implementation variations, the light-shielding display component 200 may also not be provided with the light-shielding layer 210 or the light-transmitting layer 230. The light guide layer 220 is preferably a light guide film with a thickness between 0.05 mm and 0.5 mm, which is made of a resin material with excellent light guiding performance such as PMMA or PC. The light guide layer 220 includes a light incident end 222 opposite to the light source (more specifically, opposite to the light-emitting end of the light condensing member 160). In other words, the light condensing member 160 is positioned between the light-emitting component 151 and the light incident end 222 of the light guide layer 220 and fixed to the upper housing 110 or the lower housing 120 to be able to direct the light emitted by the light-emitting component 151 to the light incident end 222 of the light guide layer 220, and the light guide layer 220 is provided with a plurality of light-emitting microstructures 221. The light-shielding layer 210 forms the non-appearance layer of the composite rolling curtain structure, and can be subjected to processes such as silk screening, painting, coating, etc. according to requirements such as temperature resistance, heat insulation, and light shielding. The light-transmitting layer 230 forms the appearance layer of the composite rolling curtain structure, which is, for example, a fabric layer or a leather layer, and is provided with a plurality of light-transmitting portions 231 opposite to the plurality of light-emitting microstructures 221, such as a plurality of light-transmitting holes. In addition, in this embodiment, the light-shielding display component 200 further includes at least one side strip 240 for lapping with the guide rail, and the side strip 240 is disposed adjacent to the light incident end 222 of the light guide layer 220 and fixed to the light-transmitting layer 230 or the light-shielding layer 210. Preferably, the material of the side strip 240 is a soft rubber strip material such as thermoplastic polyurethane elastomer (TPU), thermoplastic polyolefin (TPO), or Teflon, which has certain tensile properties and wear resistance, and the connection manner of the side strip 240 to the light-transmitting layer 230 or the light-shielding layer 210 includes but is not limited to welding, sewing, etc. Thus, when the light-shielding display component 200 moves along the guide rail through the side strip 240, the light emitted by the light-emitting component 151 can reach the light incident end 222 of the light guide layer 220 via the light condensing member 160 and enter the light guide layer 220, and after passing through the plurality of light-emitting microstructures 221, the propagation direction is changed and the light is emitted from one side surface of the light guide layer 220 and through the light-transmitting portions 231 of the light-transmitting layer 230 into the vehicle interior.

[0054] As Figure 6 and Figure 7As shown, according to the first embodiment, the light-emitting rolling curtain device includes a lower guide rail 170. The lower guide rail 170 can be fixedly connected to the lower housing 120 through fixing members such as screws, or can be integrally formed with the lower housing 120 to improve the alignment accuracy while reducing costs. Thus, the upper housing 110, the lower housing 120, and the lower guide rail 170 together form the guiding assembly of the light-emitting rolling curtain device. A lower chute 171 is provided at the top of the lower guide rail 170. The side strip 240 can pass through an opening formed in the top wall 172 of the lower guide rail 170 and be snapped into the lower chute 171, so that the light incident end 222 of the light guide layer 220 of the composite rolling curtain structure is closely attached to the top surface of the lower guide rail 170. Preferably, the lower guide rail 170 can be manufactured by aluminum extrusion, and the required movement trajectory can be realized during the extrusion process. The side strip 240 is snapped into the lower chute 171 to be able to slide along the lower chute 171 to deploy or retract the light-shielding display assembly 200, and can limit the light-shielding display assembly 200 in the Y direction and the Z direction to ensure that the relative position between the light-shielding display assembly 200 and the light source assembly 100 can be maintained during the movement process. In this embodiment, the side strip 240 includes a connecting portion 241 fixedly connected to the light-transmitting layer 230 and two overhanging portions 242 symmetrically extending from both sides of the connecting portion 241 and snapped into the lower chute 171. More specifically, each overhanging portion 242 extends into the lower chute 171 through an opening formed in the top wall 172 of the lower guide rail 170, so that the top wall 172 of the lower guide rail 170 is closely clamped between the overhanging portion 242 and the composite rolling curtain structure, and the overhanging portion 242 is limited in the Y direction and the Z direction through the lower chute 171. In this fixing manner, it can be understood that the top surface of the upper protruding portion 121 of the lower housing 120 and the top surface of the top wall 172 of the lower guide rail 170 together form the lower virtual reference plane RP1 for supporting the light condensing member 160 and the composite rolling curtain structure, so that during the relative movement of the light condensing member 160 and the light guide layer 220, the optical central axes of the two can always be aligned. It can also be understood that the lower guide rail 170 is symmetrically arranged at both ends of the light-shielding display assembly 200 in the Y direction. Even if the light-shielding display assembly 200 may have a risk of sagging under the action of gravity, the relative position relationship with the light source assembly 100 can still be maintained at the light incident end 222 of the light guide layer 220, ensuring the light incident efficiency of the overall structure. In addition, in order to reduce the resistance of the side strip 240 during the sliding process, the lower guide rail 170 can be polished, or a wear-resistant and smooth coating can be sprayed on the lower guide rail 170 / the composite rolling curtain structure, or a low-friction fabric can be added between the composite rolling curtain structure and the side strip 240, etc.

[0055] In addition, after the side strip 240 and the lower guide rail 170 are clamped, there may be a small gap between the support structure and the composite rolling curtain structure, resulting in light leakage. Therefore, preferably, an additional light-shielding structure can be used for shielding to prevent the strong light of the light source from being observed. For example, as Figure 6As shown, the light-emitting rolling curtain device further includes at least one light-shielding component, such as the first light-shielding cotton 310 and the second light-shielding cotton 320 shown. Among them, one side of the first light-shielding cotton 310 is fixed to the upper housing 110, for example, by adhesion, and the other side of the first light-shielding cotton 310 abuts against the light-shielding layer 210 of the composite rolling curtain structure. And one side of the second light-shielding cotton 320 is fixed to the guide rail 170, for example, by adhesion, and the other side of the second light-shielding cotton 320 abuts against the light-transmitting layer 230 of the composite rolling curtain structure. It can be understood that the type of the light-shielding component is not restrictive. For example, other suitable types of light-shielding components such as light-shielding wool strips and light-shielding rubbers can also be used.

[0056] In order to ensure the light incident efficiency of the light guide layer 220 in the composite rolling curtain structure, the specific dimensional relationships of the core structure can be controlled. For example, the width of the light-emitting surface of the light-emitting component 151 (such as an LED) is similar to the thickness of the light condensing member 160, and is significantly greater than the thickness of the light guide layer 220. According to an exemplary but non-limiting embodiment, the encapsulation width on the light-emitting surface side of the light-emitting component 151 is about 1.4 mm, the thickness of the light condensing member 160 is about 1.5 mm, and the thickness of the light guide layer 220 (such as a light guide film) is about 0.2 mm. Therefore, even if the composite rolling curtain structure is locally distorted at the light incident end 222 of the light guide layer 220 due to the action of gravity or other possible reasons, the presence of the clamping mechanism makes the distortion angle small. And since the thickness of the light guide layer 220 is much smaller than the thickness of the light condensing member 160, even if the composite rolling curtain structure is distorted at a small angle, the light incident end 222 of the light guide layer 220 is still within the light-emitting range of the light condensing member 160.

[0057] As Figure 8As shown, according to the second embodiment, the difference from the above-mentioned first embodiment is that the light-emitting rolling curtain device includes an upper guide rail 180. The upper guide rail 180 can be fixedly connected to the upper housing 110 through fixing members such as screws, or can be integrally formed with the upper housing 110. Thus, the upper housing 110, the lower housing 120, and the upper guide rail 180 together form the guiding assembly of the light-emitting rolling curtain device. An upper sliding groove 181 is provided at the bottom of the upper guide rail 180. The side strip 240 can pass through an opening formed in the bottom wall 182 of the upper guide rail 180 and be snap-fitted into the upper sliding groove 181, so that the composite rolling curtain structure is closely attached to the top surface of the upper guide rail 180 at the light incident end 222 of the light guide layer 220. In this embodiment, the side strip 240 includes a connecting portion 241 fixedly connected to the light-shielding layer 210 and two overhanging portions 242 symmetrically extending from both sides of the connecting portion 241 and snap-fitted into the upper sliding groove 181. More specifically, each overhanging portion 242 extends into the upper sliding groove 181 through an opening formed in the bottom wall 182 of the upper guide rail 180, so that the bottom wall 182 of the upper guide rail 180 is tightly clamped between the overhanging portion 242 and the composite rolling curtain structure, and the overhanging portion 242 is limited in the Y direction and the Z direction through the upper sliding groove 181. In this fixing manner, it can be understood that the bottom surface of the lower protruding portion 111 of the upper housing 110 and the bottom surface of the bottom wall 182 of the upper guide rail 180 together constitute the upper virtual reference plane RP2 for supporting the light condensing member 160 and the composite rolling curtain structure, so that during the relative movement of the light condensing member 160 and the light guide layer 220, the optical central axes of the two can always be kept aligned.

[0058] As Figure 9 shown, according to the third embodiment, the difference from the above-mentioned first embodiment is that the side strip 240 includes a connecting portion 241 fixedly connected to the light-transmitting layer 230 and a single overhanging portion 242 extending from one side of the connecting portion 241. The overhanging portion 242 is snap-fitted into the lower sliding groove 171, so as to be able to realize the unfolding or retraction of the light-shielding display assembly 200 by sliding along the lower sliding groove 171, and can limit the light-shielding display assembly 200 in the Y direction and the Z direction.

[0059] As Figure 10 shown, according to the fourth embodiment, the difference from the above-mentioned second embodiment is that the side strip 240 includes a connecting portion 241 fixedly connected to the light-shielding layer 210 and a single overhanging portion 242 extending from one side of the connecting portion 241. The overhanging portion 242 is snap-fitted into the upper sliding groove 181, so as to be able to realize the unfolding or retraction of the light-shielding display assembly 200 by sliding along the upper sliding groove 181, and can limit the light-shielding display assembly 200 in the Y direction and the Z direction.

[0060] It can be understood that the connecting portion 241 of the side strip 240 can be fixedly connected to the composite rolling curtain structure by, but not limited to, welding, sewing, etc. Taking sewing as an example, as Figure 11 shown, since the composite rolling curtain structure generally consists of three layers: a light-shielding layer 210, a light guide layer 220, and a light-transmitting layer 230, the connecting portion 241 of the side strip 240 can be sewn to the overall three layers of the composite rolling curtain structure by multiple sewing threads, or the connecting portion 241 of the side strip 240 can be sewn to the light-transmitting layer 230 by at least one sewing thread 262 in advance, and then the connecting portion 241 of the side strip 240 can be sewn to the overall three layers of the composite rolling curtain structure by at least one other sewing thread 261. By this method, since only a part of these sewing threads 261 (for example, one or more sewing threads 261) pass through the light guide layer 220, the sewing threads connecting the side strip 240 to the overall composite rolling curtain structure can be set sparser, thereby reducing the number of perforations in the light guide layer 220 and avoiding excessive perforations from affecting the light guiding efficiency. Similarly, when the side strip 240 is located above the composite rolling curtain structure, the connecting portion 241 of the side strip 240 can be sewn to the overall three layers of the composite rolling curtain structure by multiple sewing threads, or the connecting portion 241 of the side strip 240 can be sewn to the light-shielding layer 210 by at least one sewing thread in advance, and then the connecting portion 241 of the side strip 240 can be sewn to the overall three layers of the composite rolling curtain structure by at least one other sewing thread.

[0061] Considering that during the movement of the light-shielding display component 200, stress concentration may occur at the side strip 240, which may cause the light guide layer 220 to be damaged after long-term operation and affect the light effect. Therefore, as Figure 12 shown, according to the fifth embodiment, the difference from the above-mentioned second embodiment is that in order to reduce the stress concentration at the side strip 240, a lapping cloth 250 can be added between the side strip 240 and the composite rolling curtain structure. One end of the lapping cloth 250 is fixedly connected to the connecting portion 241 of the side strip 240, and the other end of the lapping cloth 250 is fixedly connected to the light-shielding layer 210 of the composite rolling curtain structure (it can be fixedly connected to the overall three layers of the composite rolling curtain structure or only to the light-shielding layer 210). In this embodiment, the bottom surface of the lower protruding portion 111 of the upper housing 110 constitutes the upper virtual reference plane RP2 for supporting the light condensing member 160 and the composite rolling curtain structure. Similarly, the lapping cloth 250 can also be located below the composite rolling curtain structure, that is, one end of the lapping cloth 250 is fixedly connected to the connecting portion 241 of the side strip 240, and the other end of the lapping cloth 250 is fixedly connected to the light-transmitting layer 230 of the composite rolling curtain structure.

[0062] In some applications, considering that the composite rolling curtain structure has a relatively large weight, a strut assembly 270 can be introduced to support the composite rolling curtain structure. More specifically, as Figures 13 to 16As shown, according to the sixth embodiment, the difference from the above embodiments lies in that the light-shielding display component 200 includes at least one strut component 270, preferably including a plurality of strut components 270 arranged at intervals along the movement direction F of the rolling curtain. The strut component 270 extends along the Y direction and is fixedly connected to the light-shielding layer 210, so as to make the composite rolling curtain structure closely fit the bottom surface of the bottom wall 192 of the light guide layer 220 and the guide rail 190 by supporting the light-shielding layer 210 of the composite rolling curtain structure. More specifically, in the illustrated embodiment, the strut component 270 includes a strut sleeve 272 extending along the Y direction, a fixing cloth 273, and a strut shaft 274. Among them, the strut sleeve 272 is sleeved on the strut shaft 274, and a slider 271 is fixedly arranged at the end of the strut sleeve 272 adjacent to the light incident end 222 of the light guide layer 220. The fixing cloth 273 is sleeved on the strut shaft 274 between the strut shaft 274 and the strut sleeve 272 and is fixedly connected to the light-shielding layer 210. Thus, the strut shaft 274 is fixedly connected to the light-shielding layer 210 through the fixing cloth 273. According to an implementation variant, the fixing cloth 273 may not be provided, and the strut shaft 274 may be fixedly connected to the light-shielding layer 210 by passing through the pleated protrusions integrally formed on the light-shielding layer 210. The guide rail 190 is provided with a chute 191, and the slider 271 is arranged in the chute 191 and can slide along the chute 191 to realize the unfolding or winding of the light-shielding display component 200. In this embodiment, the bottom surface of the bottom wall 192 of the guide rail 190 constitutes the upper virtual reference plane RP2 for supporting the composite rolling curtain structure.
