Abstract
Description
Technical Field
[0001] The present application relates to the technical field of automobile trim strips, and in particular to a water-cut assembly and a vehicle. Background Art
[0002] With the advancement of vehicle technology, vehicles often feature watertight seals, the most important sealing strips in the vehicle's sealing system. When in use, these seals adhere closely to the vehicle window glass, providing waterproofing, dustproofing, shock absorption, and sealing. Because these seals also protrude beyond the window glass, serving as decorative features, they must meet high aesthetic standards. Currently, to enhance the practicality of these seals, luminous features are being added to them. However, these luminous seals are relatively thick, which can limit their miniaturization. Utility Model Content
[0003] The embodiments of the present application provide a water-cutting assembly and a vehicle, which can reduce the thickness of the vehicle's water-cutting and adapt to the miniaturization development trend of vehicle water-cutting.
[0004] In a first aspect, the present application provides a water jet assembly, the water jet assembly comprising:
[0005] A water-cut body, the water-cut body having a receiving space, the water-cut body including an outer decorative panel, the outer decorative panel having an inner surface, the inner surface being used to face the interior of the vehicle; and
[0006] A light emitting module forms part of the exterior panel.
[0007] It is understandable that in the relevant technology, the water-cut assembly has achieved a certain degree of lighting and indication functions, but in actual use, the durability and stability of the water-cut assembly with lighting function mainly depend on the physical thickness of the water-cut assembly. This leads to the problem of large thickness of the water-cut assembly in actual use, which easily leads to the limitation of miniaturization and lightweight of the water-cut assembly, which is not conducive to the effective use of the interior space of the vehicle.
[0008] Therefore, in the technical solution of the present application, on the one hand, by making the light-emitting module form part of the exterior panel, not only can the shape of the exterior panel be made more aesthetically pleasing, but the exterior panel can also realize the interactive function of luminescence, thereby making the exterior panel have both decorative and luminous functions, and improving the appearance performance of the exterior panel. On the other hand, by making the light-emitting module form part of the exterior panel, the light-emitting module can be arranged close to the exterior surface of the water-cut assembly, which is beneficial for reducing the distance between the light-emitting module and the exterior surface of the water-cut assembly in the thickness direction of the water-cut assembly on the basis of realizing the illumination of the water-cut assembly, thereby thinning the thickness of the water-cut assembly, thereby enabling the water-cut assembly to adapt to the development trend of miniaturization and lightness, and improving the space utilization rate of the vehicle when the water-cut assembly is applied to the vehicle.
[0009] Alternatively, the light emitting module is connected to the inner surface of the exterior panel.
[0010] It is understandable that by connecting the light-emitting module to the inner surface of the exterior panel, the connection between the light-emitting module and the exterior panel can be directly achieved. On the one hand, connecting the light-emitting module to the inner surface of the exterior panel saves the related costs required to set up additional structural parts to support the light-emitting module, thereby reducing the overall cost of the water-cut assembly. It also makes the structure stacked along the thickness direction of the water-cut assembly simpler and more convenient to assemble, which is conducive to improving the quality and stability of the water-cut assembly, thereby improving the yield of the water-cut assembly. On the other hand, connecting the light-emitting module to the inner surface of the exterior panel can reduce the number of structural parts stacked along the thickness direction of the water-cut assembly, making the installation more compact, which is conducive to reducing the thickness of the water-cut assembly, making the water-cut assembly lighter and thinner, reducing the space occupied by the thickness direction of the water-cut assembly, and better adapting to the development trend of lightweight and thin water-cut assemblies.
[0011] Alternatively, a light-distributing structure is provided on the inner surface of the exterior panel, the light-emitting module is located in the accommodating space, and the light emitted by the light-emitting module passes through the light-distributing structure and then emerges from the exterior panel.
[0012] As you can understand, in optics, haze is a physical quantity that describes the degree to which light is scattered due to minute inhomogeneities in a medium. The higher the haze value, the shorter the required mixing distance for the light source in the water-cut assembly. Therefore, increasing the haze value in a water-cut assembly is crucial for optimizing its thickness.
[0013] Therefore, in the technical solution of the present application, a light-uniforming structure is provided on the inner surface of the exterior panel, and the light emitted by the light-emitting module passes through the light-uniforming structure and then exits the exterior panel. This can not only effectively control the scattering and refraction of light, reduce reflection and light leakage, and thus produce a more uniform and soft light distribution, but also improve the light uniformity and haze value of the water-cut assembly. The increase in haze value can shorten the light mixing distance required by the light source in the water-cut assembly. The shortening of the light mixing distance means that the space in the thickness direction of the water-cut assembly can be compressed. Therefore, by providing a light-uniforming structure on the inner surface of the exterior panel, the thickness of the water-cut assembly can be reduced, which is conducive to the miniaturization and thinning of the water-cut assembly.
[0014] In one possible embodiment, the light-emitting module includes a light-transmitting layer, a light-guiding layer, a conductive circuit layer, a light-emitting diode and a plastic encapsulation layer. The light-transmitting layer includes a first surface and a second surface. The first surface and the second surface are arranged opposite to each other in the thickness direction of the light-transmitting layer. The first surface forms at least part of the outer surface of the exterior panel, and the outer surface is used to face the outside of the vehicle. The light-guiding layer is arranged on the second surface, the conductive circuit layer is arranged on the surface of the light-guiding layer away from the light-transmitting layer and is electrically connected to the conductive circuit layer. The light-emitting diode is arranged on the surface of the conductive circuit layer away from the light-guiding layer. At least part of the plastic encapsulation layer is arranged on the surface of the conductive circuit layer away from the light-guiding layer and encapsulates the light-emitting diode.
[0015] In a possible implementation, the exterior panel includes a plastic body, and the plastic body is connected to the light-emitting module to form an integrated structure.
[0016] In a possible implementation manner, the sum of the thickness of the plastic body and the thickness of the light-emitting module is less than or equal to 4.5 mm.
[0017] In one possible embodiment, the light-transmitting layer includes a base material layer and a pattern layer that are stacked together, wherein a surface of the base material layer facing away from the pattern layer forms the first surface, the pattern layer is connected between the base material layer and the light-guiding layer, and the pattern layer has a transparent area;
[0018] In the thickness direction of the light emitting module, the projection of the transparent area on the light guide layer covers at least a portion of the projection of the light emitting diode on the light guide layer.
[0019] In one possible embodiment, the exterior panel has a light-emitting area, the light-emitting module includes a surface light source, the surface light source is connected to the inner surface, and in the thickness direction of the water-cutting assembly, the projection of the surface light source on the exterior panel covers the light-emitting area.
[0020] In a possible implementation manner, the sum of the thickness of the exterior panel, the thickness of the adhesive layer, and the thickness of the surface light source is less than or equal to 6 mm.
[0021] In a possible implementation, the light-homogenizing structure includes a plurality of protrusions, and the plurality of protrusions are arranged in an array on the inner surface.
[0022] In one possible implementation, a protrusion height of the protrusion relative to the inner surface is in the range of 6 μm to 8 μm;
[0023] The diameter of the protrusion is in the range of 6um-8um, or the diameter of the protrusion is in the range of 20um-25um.
[0024] In a second aspect, the present application also provides a vehicle, comprising window glass, body sheet metal, and the water-cut assembly as described above, wherein the water-cut assembly is connected between the window glass and the body sheet metal. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0036] For ease of understanding, the terms involved in the embodiments of the present application are first explained.
[0037] And / or: It is just a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.
[0038] Multiple: refers to two or more than two.
[0039] Connection: should be understood in a broad sense. For example, A and B are connected, which can be either directly connected or indirectly connected through an intermediary.
[0040] The specific implementation of the present application will be clearly described below with reference to the accompanying drawings.
[0041] Embodiments of the present application provide a water jet assembly and a vehicle.
[0042] See also Figure 1 , Figure 1 It is a simplified structural diagram of a vehicle 200 provided in an embodiment of the present application.
[0043] Vehicle 200 may include a window glass 210, a body sheet metal 220, and a water-cut assembly 100. The window glass 210 may be mounted on a viewing window of the body sheet metal 220, and the water-cut assembly 100 may be mounted on the body sheet metal 220 and abut against the window glass 210, thereby being connected between the window glass 210 and the body sheet metal 220. The water-cut assembly 100 may be used to seal the gap between the window glass 210 and the viewing window of the body sheet metal 220 and to decorate the body sheet metal 220.
[0044] For ease of description, the length of the water jet assembly 100 is defined as the X direction, the width of the water jet assembly 100 is defined as the Y direction, and the thickness of the water jet assembly 100 is defined as the Z direction. The X, Y, and Z directions are perpendicular to each other. The length of the water jet assembly 100 can be parallel or substantially parallel to the direction of travel of the vehicle 200.
[0045] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 2 is a partial structural diagram of the water jet assembly 100 provided in an embodiment of the present application. Figure 3 It is along Figure 2 The schematic diagram of a partial cross-section taken along section line AA is shown. The water-cut assembly 100 may include a water-cut body 10 and a light-emitting module (not shown). The water-cut body 10 has a receiving space W. The light-emitting module is located within the receiving space W of the water-cut body 10, or alternatively, the light-emitting module constitutes a portion of the water-cut body 10. The light-emitting module can emit light outward, providing the water-cut assembly 100 with a lighting function.
[0046] As is understandable, since the watertight assembly 100 serves as both a seal and a decorative component, it has high aesthetic requirements. By incorporating a light-emitting module into the watertight body 10, the watertight assembly 100 achieves interactive luminous functionality. This not only enhances the aesthetics of the watertight assembly 100 and improves its appearance, but also clearly displays the vehicle's outline at night and in dimly lit environments, improving safety for drivers on nighttime roads.
[0047] It should be noted that Figure 1-Figure 3 The purpose is only to schematically describe the connection relationship between the water-cutting body 10, the light-emitting module and the wiring harness, and is not to specifically limit the connection position, specific structure and quantity of each component. The structure shown in the embodiment of the present application does not constitute a specific limitation on the water-cutting assembly 100. In other embodiments of the present application, the water-cutting assembly 100 may include Figure 1-Figure 3 More or fewer components may be shown, or some components may be combined or separated, or the components may be arranged differently. Figure 1-Figure 3The components shown can be implemented in hardware, software, or a combination of software and hardware.
[0048] Please refer to Figure 2 and Figure 3 , the water-cut body 10 may include an exterior trim 20 and a sealing strip 30. Among them, the exterior trim 20 is the portion of the water-cut body 10 that is exposed to the outside of the vehicle 200, and it may be the appearance part of the water-cut assembly 100. The exterior trim 20 has the properties of high strength, scratch resistance, corrosion resistance, heat resistance, transparency, and good electrical properties, and the surface may be chrome-plated and painted. The exterior trim 20 may be made of a light-transmitting material. For example, the exterior trim 20 may be in the shape of a cover and made of a light-transmitting plastic material. Under this setting, since the exterior trim 20 is made of plastic material, the weight of the water-cut assembly 100 can be greatly reduced compared to aluminum alloy or stainless steel materials.
[0049] The exterior panel 20 can extend along the X-direction and includes a first end 21 and a second end 22. The first end 21 and the second end 22 of the exterior panel 20 are arranged opposite each other in the X-direction. In other words, the first end 21 and the second end 22 of the exterior panel 20 represent the first and last ends of the exterior panel 20 along the X-direction. The exterior panel 20 has a light-emitting area 201, which can extend from the first end 21 to the second end 22 of the exterior panel 20. Within the exterior panel 20, the area through which light emitted by the light-emitting module can pass is the light-emitting area 201 of the exterior panel 20. The length of the luminous area 201 of the exterior panel 20 in the X direction can be equal to or slightly smaller than the extension length between the first end 21 of the exterior panel 20 and the second end 22 of the exterior panel 20, so as to achieve full-range illumination of the entire exterior panel 20, thereby eliminating as many non-luminous dark areas in the exterior panel 20 as possible and improving the luminous effect of the water-cutting assembly 100.
[0050] The exterior trim panel 20 may include an outer surface 202 and an inner surface 203. The inner surface 203 of the exterior trim panel 20 and the outer surface 202 of the exterior trim panel 20 are disposed opposite each other along the thickness direction (i.e., the Z direction) of the exterior trim panel 20. The outer surface 202 of the exterior trim panel 20 is the surface of the exterior trim panel 20 facing the outside of the vehicle 200, and the inner surface 203 of the exterior trim panel 20 is the surface of the exterior trim panel 20 facing the inside of the vehicle 200.
[0051] In one possible embodiment, the water-jet assembly 100 may further include a paint layer (not shown). The paint layer is connected to the outer surface 202 of the exterior panel 20 and is located in the luminous area 201 of the exterior panel 20. Light emitted by the light-emitting module can be emitted through the luminous area 201 and the paint layer. For example, the exterior panel 20 and the paint layer can be combined through a spraying process. After the exterior panel 20 is sprayed with topcoat, the luminous area 201 is laser engraved, and then semi-transparent ink and varnish are sprayed on to form the paint layer.
[0052] It can be understood that the water-repellent assembly 100 is an exterior trim component for a vehicle 200 that meets both optoelectronic and aesthetic requirements. When mounted on a vehicle body panel 220, the water-repellent assembly 100 provides a seal between the vehicle body panel 220 and the window glass 210, as well as provides illumination. By designing the material, brightness, color, and other aesthetic characteristics of the outermost exterior panel 20 within the water-repellent assembly 100, the water-repellent assembly 100 can be given a variety of decorative styles.
[0053] Please continue reading Figure 3 The sealing strip 30 can extend along the X direction and dock with the outer panel 20, so that the outer panel 20 and the sealing strip 30 can enclose and form a receiving space W for the water-cut body 10. For example, the sealing strip 30 and the outer panel 20 can be connected by snapping. Alternatively, the sealing strip 30 and the outer panel 20 can also be connected by welding. Alternatively, the sealing strip 30 and the outer panel 20 can also be connected by bonding. It only needs to be satisfied that the sealing strip 30 and the outer panel 20 can be connected to form the receiving space W for the water-cut body 10, and the embodiments of the present application do not impose strict restrictions on this.
[0054] It is understandable that in the relevant technology, the water-cut assembly 100 has achieved a certain degree of lighting and indication functions, but in actual use, the durability and stability of the water-cut assembly 100 with lighting function mainly depend on the physical thickness of the water-cut assembly 100. This leads to the problem of large thickness of the water-cut assembly 100 in actual use, which easily leads to the limitation of miniaturization and lightweight of the water-cut assembly 100, which is not conducive to the effective use of the internal space of the vehicle 200.
[0055] Based on this, in the embodiments of the present application, by adjusting the setting position of the light-emitting module or the structure of the water-cut assembly 100, the thickness of the water-cut assembly 100 can be reduced and the space utilization inside the vehicle 200 can be improved, which will be specifically explained below through three specific embodiments.
[0056] First embodiment:
[0057] Please refer to Figure 2 and Figure 4 , Figure 4 It is along Figure 2 The section line BB shown is a schematic cross-sectional view of a partial structure of the water jetting assembly 100 according to the first embodiment of the present application.
[0058] In this embodiment, the light emitting module 40 forms part of the outer panel 20. The light emitting module 40 forming part of the outer panel 20 means that the light emitting module 40 is disposed in the outer panel 20 and together with other structures of the outer panel 20 constitutes the outer panel 20.
[0059] On the one hand, by forming the light-emitting module 40 as part of the exterior panel 20, not only can the exterior panel 20 be made more aesthetically pleasing, but the exterior panel 20 can also realize the interactive function of luminescence, thereby making the exterior panel 20 have both decorative and luminous functions, thereby improving the appearance performance of the exterior panel 20. On the other hand, by forming the light-emitting module 40 as part of the exterior panel 20, the light-emitting module 40 can be arranged close to the exterior surface of the water-cut assembly 100, which is beneficial for reducing the distance between the light-emitting module 40 and the exterior surface of the water-cut assembly 100 in the thickness direction (i.e., the Z direction) of the water-cut assembly 100 while realizing the illumination of the water-cut assembly 100, thereby reducing the thickness of the water-cut assembly 100, thereby enabling the water-cut assembly 100 to adapt to the development trend of miniaturization and thinness, and improving the space utilization rate of the vehicle 200 when the water-cut assembly 100 is applied to the vehicle 200.
[0060] Please refer to Figure 2 and Figure 4 , the exterior panel 20 may include a plastic body 23. The plastic body 23 may be connected to the light-emitting module 40 to form an integrated structure. That is, the exterior panel 20 may be an integrated structure. The plastic body 23 and the light-emitting module 40 are connected to form an integrated structure, which means that the plastic body 23 and the light-emitting module 40 may be formed into an integrated structure by a method such as integral molding, or the plastic body 23 and the light-emitting module 40 may be formed into an integrated structure by an assembly direction such as bonding or welding. For example, the light-emitting module 40 may be placed in a molding mold, and the required exterior panel 20 may be prepared by in-mold injection molding.
[0061] It is understandable that, since the exterior trim panel 20 is an integrated structure, the exterior trim panel 20 has fewer parts, which is conducive to simplifying the manufacturing process of the exterior trim panel 20 and improving the production and assembly efficiency of the water-cutting assembly 100.
[0062] In this embodiment, the sum of the thickness of the plastic body 23 (i.e., the dimension of the plastic body 23 along the Z direction) and the thickness of the light-emitting module 40 (i.e., the dimension of the light-emitting module 40 along the Z direction) can be less than or equal to 4.5 mm. For example, the thickness of the plastic body 23 can be less than or equal to 2 mm, and the thickness of the light-emitting module 40 can be 2 mm.
[0063] It can be understood that in the relevant technology, the sum of the thickness of the plastic body 23 and the thickness of the light-emitting module 40 is usually greater than 10 mm. In this embodiment, by making the sum of the thickness of the light-emitting module 40 and the plastic body 23 less than or equal to 4.5 mm, the space occupied by the water-cutting assembly 100 in its thickness direction can be greatly reduced, thereby realizing the miniaturization and lightweight of the water-cutting assembly 100. It can also provide the water-cutting assembly 100 with good durability and stability while satisfying the lighting function of the water-cutting assembly 100.
[0064] Please refer to Figure 4 and Figure 5 , Figure 5 It is along Figure 2 The section line BB shown is another schematic cross-sectional view of a partial structure of the water jet assembly 100 according to the first embodiment of the present application.
[0065] The light-emitting module 40 can form the appearance surface of at least part of the exterior panel 20. In the Z direction, the projection area of the light-emitting module 40 on the exterior panel 20 can cover the light-emitting area 201 of the exterior panel 20, so that the light emitted by the light-emitting module 40 can be emitted to the outside of the water-cutting assembly 100. The light-emitting module 40 may include a light-transmitting layer 41, a light-guiding layer 42, a conductive circuit layer 43, a light-emitting diode 44 and a plastic sealing layer 45. In the direction from the outside of the vehicle 200 to the inside of the vehicle 200, the light-transmitting layer 41, the light-guiding layer 42, the conductive circuit layer 43 and the plastic sealing layer 45 can be stacked in sequence, and the light-emitting diode 44 is arranged on the conductive circuit layer 43 and encapsulated by the plastic sealing layer 45. When the circuit in the conductive circuit layer 43 is turned on, the light-emitting diode 44 can be controlled to emit light. The light emitted by the LED 44 can be transmitted to the light guide layer 42 , and after the light guide layer 42 evens out the light and improves the light conversion efficiency, it is finally emitted outward through the light-transmitting layer 41 to realize the light-emitting function of the light-emitting module 40 .
[0066] The light-emitting module 40 can be manufactured using an IME (In Mold Electronics) process. Compared to conventional light-emitting modules 40, the light-emitting module 40 manufactured in this embodiment can have a smaller thickness, occupy less space in the Z direction, and have lower manufacturing costs. This helps optimize the space occupied by the water-jet assembly 100 and adapts to the trend of lightweight and thin water-jet assembly 100.
[0067] Specifically, the light-transmitting layer 41 may include a first surface 411 and a second surface 412. The first surface 411 and the second surface 412 of the light-transmitting layer 41 may be disposed opposite to each other in the thickness direction (i.e., the Z direction) of the light-transmitting layer 41. The first surface 411 of the light-transmitting layer 41 may form at least a portion of the outer surface 202 of the exterior panel 20.
[0068] In one possible implementation, Figure 5 As shown, the light-transmitting layer 41 may include a base material layer 413 and a pattern layer 414 that are stacked.
[0069] The surface of the substrate layer 413 facing away from the pattern layer 414 faces the exterior of the vehicle 200. The surface of the substrate layer 413 facing away from the pattern layer 414 not only forms the first surface 411 of the light-transmitting layer 41, but also forms at least a portion of the outer surface 202 of the exterior trim panel 20. The substrate layer 413 can be made of a light-transmitting material (e.g., a transparent or translucent material).
[0070] The surface of the pattern layer 414 facing away from the substrate layer 413 faces the interior of the vehicle 200 and is used to connect to the light guide layer 42, so that the pattern layer 414 is connected between the substrate layer 413 and the light guide layer 42. The pattern layer 414 may include decorative elements. The decorative elements may include one or more combinations of numbers, letters, symbols, and shapes.
[0071] For example, the decorative elements may include the numbers 1, 2, and 3. Furthermore, the decorative elements may be painted in colors such as black, white, blue, green, or red to block light from transmitting through the pattern layer 414. The pattern layer 414 may be formed on the substrate layer 413 using IMD (In-Mold Decoration) technology, post-molding technology, spray coating technology, laser etching technology, hot foil transfer technology, direct printing technology, or the like.
[0072] In this embodiment, the pattern layer 414 may have a transparent region 415. In the thickness direction (i.e., the Z direction) of the light-emitting module 40, the projection of the transparent region 415 on the light-guiding layer 42 may cover at least a portion of the projection of the light-emitting diode 44 on the light-guiding layer 42. In this configuration, the transparent region 415 of the pattern layer 414 may be disposed in the illumination path of the light emitted by the light-emitting diode 44, so that the light emitted by the light-emitting diode 44 can be emitted through the transparent region 415.
[0073] Of course, in other embodiments, in the thickness direction of the light-emitting module 40 (i.e., the Z direction), the projection of the transparent area 415 on the light-guiding layer 42 can be at least partially offset or completely offset with the projection of the light-emitting diode 44 on the light-guiding layer 42, and there is no strict limitation on this.
[0074] In this embodiment, the light guide layer 42 is disposed on the second surface 412 of the light-transmitting layer 41. The light guide layer 42 receives light emitted by the light-emitting diodes 44 and transmits the light emitted by the light-emitting diodes 44 to the exterior of the water-cutting assembly 100. The light guide layer 42 can be a rigid structure. Alternatively, the light guide layer 42 can be a flexible structure. Alternatively, the light guide layer 42 can be a combination of a rigid and flexible structure.
[0075] The conductive circuit layer 43 is provided on the surface of the light-guiding layer 42 away from the light-transmitting layer 41. The conductive circuit layer 43 may be a flexible printed circuit (FPC), a rigid circuit board, or a rigid-flexible circuit board. In addition, the conductive circuit layer 43 may have a perforation 416. The perforation 416 may penetrate the conductive circuit layer 43 along the thickness direction of the conductive circuit layer 43. The perforation 416 may allow light emitted by the light-emitting diode 44 to pass through and / or allow the circuit in the light-emitting module 40 to pass through. The number of perforations 416 may be one or more. When the number of perforations 416 is multiple, the multiple perforations 416 may be arranged at intervals on the conductive circuit layer 43.
[0076] Exemplarily, the light guide layer 42 may be a flexible light guide strip. The conductive circuit layer 43 may be a flexible circuit board. It is understandable that, since flexible circuit boards and flexible light guide strips can be bent, folded, or repeatedly moved in a variety of ways, they have the advantages of being light, thin, and flexible compared to ordinary rigid circuit boards and rigid light guide strips. Furthermore, since the light-emitting module 40 will form part of the exterior panel 20, and the exterior panel 20 is often of a special-shaped design, the use of flexible circuit boards and flexible light guide strips with good bending properties can adapt to the special shape of the exterior panel 20 by bending and deforming the flexible circuit board and the flexible light guide strip, thereby improving reliability.
[0077] Light-emitting diodes 44 are disposed on the surface of conductive circuit layer 43 facing away from light-guiding layer 42 and are electrically connected to conductive circuit layer 43. Light-emitting diodes 44 emit light toward light-guiding layer 42, allowing light emitted by light-emitting diodes 44 to be transmitted through the light-guiding strip and emitted outward. For example, light-emitting diodes 44 may be miniature light-emitting diodes (Mini LEDs).
[0078] Among them, the light emitting diodes 44 can emit light in colors such as white, blue, red, yellow, green, etc. The number of light emitting diodes 44 can be one or more. When the number of light emitting diodes 44 is multiple, the multiple light emitting diodes 44 can be spaced apart on the surface of the conductive circuit layer 43 away from the light guide layer 42, and form a physical fixed connection and electrical connection with the conductive circuit layer 43. The multiple light emitting diodes 44 can be electrically connected or communicatively connected to the vehicle 200 control module of the vehicle 200 through a wiring harness, so that the shape and style of the light emitted by the multiple light emitting diodes 44 can be controlled by the vehicle 200 control module to enhance the diversity of light emission, such as controlling the lighting order, brightness and other lighting effects of the multiple light emitting diodes 44, thereby achieving different appearance effects.
[0079] It can be understood that multiple light-emitting diodes 44 are arranged in sequence along the length direction of the exterior panel 20 (i.e., the X direction), so that the exterior panel 20 can emit light from the light-emitting diodes 44 at different positions along its length direction, effectively avoiding light decay, ensuring the uniformity of light emission of the water-cutting assembly 100 along its length direction, and realizing surface light emission, and then realizing customized pattern light emission, which greatly improves the working performance of the water-cutting assembly 100.
[0080] In one possible embodiment, the light-emitting module 40 may further include electronic components 49. The electronic components 49 are connected to the surface of the conductive circuit layer 43 facing away from the light-guiding layer 42 and are electrically connected to the conductive circuit layer 43. The electronic components 49 are spaced apart from the light-emitting diodes 44 and covered by the plastic layer 45. The electronic components 49 may include a combination of one or more capacitors, resistors, or inductors. The electronic components 49 can be used to control the light-emitting effect of the light-emitting module 40. By adjusting the number of electronic components 49, the resistance value, etc., the light-emitting module 40 can achieve the desired light-emitting function.
[0081] Illustratively, there may be a plurality of electronic components 49 , and the plurality of electronic components 49 may all be connected to a surface of the conductive circuit layer 43 facing away from the light guide layer 42 , and electrically connected to the conductive circuit layer 43 .
[0082] In this embodiment, at least part of the plastic sealing layer 45 is provided on the surface of the conductive circuit layer 43 away from the light guide layer 42, and encapsulates the light-emitting diode 44. The plastic sealing layer 45 can be connected to the plastic body 23 to form an integrated structure, so that the light-emitting module 40 and the plastic body 23 together constitute the exterior panel 20. The material of the plastic sealing layer 45 can be the same as or different from the material of the plastic body 23. For example, the material of the plastic sealing layer 45 can be the same as or similar to the material of the plastic body 23. The material of the plastic sealing layer 45 can be PC (Polycarbonate) material. The material of the plastic body 23 can be PC material, ABS (Acrylonitrile Butadiene Styrene) material or PMMA (Polymethyl Methacrylate) material.
[0083] Based on the above description, it should be understood that in this embodiment, the light-transmitting layer 41, light-guiding layer 42, conductive circuit layer 43, electronic components 49, and light-emitting diodes 44 can be integrated and injection-molded together to form a functional film. This functional film can then be molded into the exterior panel 20 through in-mold injection molding, allowing the exterior panel 20 to achieve the desired decorative and luminous functions. In addition, the process of forming the integrated exterior panel 20 through injection molding is simpler and helps reduce the overall thickness of the water-cut assembly 100.
[0084] Second embodiment:
[0085] See also Figure 6 , Figure 6 It is along Figure 2 The section line BB shown is a cross-sectional view of a portion of the structure of the water jet assembly 100 of the second embodiment of the present application. It should be noted that the various structures of the water jet assembly 100 described below can be applied to the water jet assembly 100 provided in the first embodiment unless there is any conflict.
[0086] In this embodiment, the same details as in the first embodiment are omitted. Unlike the first embodiment, the light-emitting module 40 is connected to the inner surface 203 of the exterior panel 20. The light-emitting module 40 can be manufactured using a COB (Chip on Board) flip-chip packaging process. The light-emitting module 40 manufactured using the COB flip-chip packaging process does not have a bracket structure, thereby saving the Z-direction space occupied by the bracket that would otherwise be required to support the light-emitting structure of the light-emitting module 40. This facilitates reducing the thickness of the water-cut assembly 100 and achieving a higher density and higher brightness configuration of the light-emitting module 40.
[0087] It is understood that by connecting the light-emitting module 40 to the inner surface 203 of the exterior panel 20, the light-emitting module 40 can be directly connected to the exterior panel 20. Connecting the light-emitting module 40 to the inner surface 203 of the exterior panel 20 saves the cost associated with additional structural components required to support the light-emitting module 40, thereby reducing the overall cost of the water-cut assembly 100. Furthermore, the stacking structure of the water-cut assembly 100 along the Z direction is simplified, making assembly more convenient, which helps improve the quality and stability of the water-cut assembly 100 and, in turn, the yield rate of the water-cut assembly 100. Furthermore, connecting the light-emitting module 40 to the inner surface 203 of the exterior panel 20 reduces the number of structural components stacked along the Z direction of the water-cut assembly 100, resulting in a more compact installation. This helps reduce the thickness of the water-cut assembly 100, making it lighter and thinner, reducing the space occupied in the Z direction, and better adapting to the trend of lightweight and thin water-cut assemblies 100.
[0088] In this embodiment, the light-emitting module 40 may include a surface light source 46 and a circuit board (not shown). The surface light source 46 may be connected to the inner surface 203 of the outer panel 20. In the Z direction, the projection of the surface light source 46 on the outer panel 20 may cover the light-emitting area 201 of the outer panel 20. It is understandable that by making the light-emitting module 40 include a surface light source 46, the outer panel 20 may have light emitted by the surface light source 46 at different positions along its length, thereby effectively avoiding light decay, ensuring the uniformity of the light emission of the water-cut assembly 100, and realizing surface illumination. By making the projection of the surface light source 46 on the outer panel 20 cover the light-emitting area 201 of the outer panel 20, the coverage of the surface light source 46 may be effectively expanded, achieving a more uniform light-emitting effect and brightness, and improving the overall visual effect and compatibility.
[0089] The circuit board can be disposed on a side of the surface light source 46 away from the exterior panel 20 and electrically connected to the surface light source 46. The circuit board can be a flexible circuit board, a rigid circuit board, or a rigid-flexible circuit board.
[0090] In one possible implementation, Figure 6 As shown, the light-emitting module 40 may further include an adhesive layer 47. The adhesive layer 47 is connected between the inner surface 203 of the exterior panel 20 and the surface light source 46, so that the surface light source 46 is fixedly connected to the exterior panel 20 via the adhesive layer 47. With this arrangement, the light-emitting module 40 can be fixed to the exterior panel 20 without affecting the lighting effect of the light-emitting module 40, and the adhesive bonding can reduce the space wasted during assembly.
[0091] Among them, the adhesive layer 47 can be an OCA (Optically Clear Adhesive) layer. The use of the OCA layer to connect the exterior panel 20 and the light-emitting module 40 can effectively compress the structural space of the water-cut assembly 100 along the Z direction. For example, the thickness of the light-emitting module 40 (that is, the size of the light-emitting module 40 along the Z direction) can be 3 mm. The thickness of the OCA layer (that is, the size of the OCA layer along the Z direction) can be 0.1 mm to 0.5 mm (including the endpoint values 0.1 mm and 0.5 mm). The thickness of the exterior panel 20 (that is, the size of the exterior panel 20 along the Z direction) can be 2.5 mm. Therefore, the sum of the thickness of the stacking structure composed of the light-emitting module 40, the OCA layer and the exterior panel 20 (that is, the size of the stacking structure along the Z direction) can be less than or equal to 6 mm. In other words, the sum of the thickness of the exterior panel 20, the thickness of the adhesive layer 47 and the thickness of the surface light source 46 can be less than or equal to 6 mm.
[0092] Third embodiment:
[0093] Please refer to Figure 7 and Figure 8 , Figure 7This is a partial structural diagram of the water jet assembly 100 of the third embodiment of the present application. Figure 8 It is another partial structural diagram of the water jet assembly 100 of the third embodiment of the present application. It should be noted that the various structures of the water jet assembly 100 described below can be applied to the water jet assembly 100 provided in the first and second embodiments unless there is any conflict.
[0094] In this embodiment, the details common to the first embodiment are omitted. However, unlike the first embodiment, a light-distributing structure 50 is provided on the inner surface 203 of the exterior panel 20. The light-emitting module 40 is located within the accommodation space W of the water-cut body 10. Light emitted by the light-emitting module 40 passes through the light-distributing structure 50 and exits the exterior panel 20. The light-distributing structure 50 can be formed by plasma etching the inner surface 203 of the exterior panel 20. For example, plasma etching can increase the haze value of the surface of the water-cut assembly 100 to 95%.
[0095] It is understood that in optics, haze is a physical quantity that describes the degree to which light is scattered due to minute inhomogeneities when passing through a medium. The higher the haze value, the smaller the required light mixing distance for the light source in the water-cut assembly 100. Therefore, increasing the haze value in the water-cut assembly 100 is crucial for optimizing the thickness of the water-cut assembly 100.
[0096] Therefore, in this embodiment, a light-homogenizing structure 50 is provided on the inner surface 203 of the outer panel 20, and the light emitted by the light-emitting module 40 passes through the light-homogenizing structure 50 and then exits the outer panel 20. This can not only effectively control the scattering and refraction of light, reduce reflection and light leakage, and thus produce a more uniform and soft light distribution, but also improve the light homogeneity and haze value of the water-cut assembly 100. The improvement in the haze value can shorten the light mixing distance required by the light source in the water-cut assembly 100. The shortening of the light mixing distance means that the space in the Z direction can be compressed. Therefore, by providing a light-homogenizing structure 50 on the inner surface 203 of the outer panel 20, the thickness of the water-cut assembly 100 can be reduced, which is conducive to the miniaturization and thinning of the water-cut assembly 100.
[0097] In this embodiment, the light-homogenizing structure 50 may include a plurality of protrusions 51 arranged in an array on the inner surface 203 of the exterior panel 20. It is understood that by providing the plurality of micro-nano-scale protrusions 51 on the inner surface 203 of the exterior panel 20, not only can the haze value be increased, achieving a more uniform and soft light distribution, effectively improving the light homogeneity of the water-cutting assembly 100, but also the appearance quality of the water-cutting assembly 100 can be improved, enhancing the visual effect and user experience.
[0098] In one possible implementation, Figure 7As shown, the light-homogenizing structure 50 may include a plurality of first protrusions 511. The plurality of first protrusions 511 may form a nanopillar array. The protrusion height H1 of each first protrusion 511 relative to the inner surface may be in the range of 6 μm to 8 μm (including the endpoints 6 μm and 8 μm). The diameter D1 of each first protrusion 511 may be in the range of 6 μm to 8 μm (including the endpoints 6 μm and 8 μm). The center-to-center distance P1 between two adjacent first protrusions 511 may be in the range of 10 μm to 13 μm (including the endpoints 10 μm and 13 μm).
[0099] In another possible implementation, Figure 8 As shown, the light-homogenizing structure 50 may include a plurality of second protrusions 512. The plurality of second protrusions 512 may form a nanosphere array. The protrusion height H2 of each second protrusion 512 relative to the inner surface may be in the range of 6 μm to 8 μm (including the endpoints 6 μm and 8 μm). The diameter D2 of each second protrusion 512 may be in the range of 20 μm to 25 μm (including the endpoints 20 μm and 25 μm). The center-to-center distance P2 between two adjacent second protrusions 512 may be in the range of 23 μm to 26 μm (including the endpoints 23 μm and 26 μm).
[0100] Of course, the shape of the protrusion 51 is not limited to the shapes listed in the two embodiments above. It can also be other shapes such as a truncated cone, a prism, etc. This embodiment does not impose strict restrictions on the shape of the protrusion 51, the spacing between two adjacent protrusions 51, the protruding height of the protrusion 51 relative to the inner surface 203 of the exterior panel 20, the outer diameter of the protrusion 51, etc.
[0101] See also Figure 9 , Figure 9 It is along Figure 2 The illustrated cross-sectional view of the light emitting module 40 according to the third embodiment of the present application is obtained by cutting along the cutting line BB.
[0102] In this embodiment, the light-emitting module 40 may include a bottom housing 481, a face shield 482, a circuit board 483, a plurality of light sources 484, and a light guide plate 485. The face shield 482 is connected to the bottom housing 481, and a sealed space Q may be formed between the face shield 482 and the bottom housing 481. The circuit board 483 is located within the sealed space Q and is connected to the bottom housing 481. The plurality of light sources 484 are located within the sealed space Q and are physically and electrically connected to the circuit board 483. The light guide plate 485 is located within the sealed space Q and is connected to the face shield 482.
[0103] It can be understood that by setting a light-homogenizing structure 50 between the light-emitting module 40 and the inner surface 203 of the exterior panel 20, the light emitted by the light source 484 can be emitted after passing through the light-homogenizing structure 50, so as to utilize the light-homogenizing structure 50 to adjust the direction of the light emitted by the light source 484, thereby shortening the light mixing distance L of the light source 484, thinning the space in the thickness direction of the water-cutting assembly 100, and making the water-cutting assembly 100 miniaturized and lightweight.
[0104] Based on the description of the above three embodiments, it should be understood that, compared with the water jet assembly 100 in the related art, the water jet assembly 100 provided in the embodiment of the present application has at least the following advantages:
[0105] First, the water-cut assembly 100 is thinner, which is beneficial to improving the utilization rate of the interior space of the vehicle 200.
[0106] 2. The light emission of the water-cut assembly 100 is more uniform, the lighting effect is better, and the safety and comfort of the vehicle 200 are improved.
[0107] 3. The water-cut assembly 100 has high installation versatility. The light-emitting module 40 can adapt to the lighting requirements of the exterior panels 20 of different models, reduce the overall installation complexity of the light-emitting module 40, and realize the vehicle-grade conversion of 3C products to meet the strict vehicle 200 specification requirements.
[0108] Fourth, the customization workload and production cost of each component in the water-jet assembly 100 are low, the production efficiency of the water-jet assembly 100 is high, and the reliability and stability of the water-jet assembly 100 are strong.

The description of the above embodiments is only used to help understand the method and core idea of the present application. At the same time, for those skilled in the art, according to the idea of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
