Description

Technical Field

[0001] This utility model belongs to the technical field of luminous decorative parts, specifically relating to a three-dimensional luminous decorative part with a floating effect and an automobile. Background Technology

[0002] With the development of automotive exterior ambient lighting, the light emission form and appearance effect of lighting products are playing an increasingly important role; commonly used exterior ambient lighting on vehicles can include illuminated lettering, logo lights, trim lights, exterior ambient lighting, illuminated bumpers, illuminated grilles, etc.

[0003] For example, CN221570351U discloses an automotive decorative light, including a faceplate, a housing, and a lamp assembly. The faceplate includes a lampshade and a diaphragm. The outer surface of the lampshade is provided with a black hard trim panel, and the end of the lampshade is welded to the housing. The diaphragm is located inside the lampshade, and its outer surface is provided with a specific pattern layer, which is located between the lampshade and the diaphragm. The lamp assembly includes a diffuser plate, a reflector bowl, and a PCBA board. The diffuser plate is detachably connected to the housing by self-tapping screws. One end of the reflector bowl abuts against the housing. The PCBA board includes LED beads. This design displays a specific effect pattern when emitting light and appears as a black hard trim panel when not emitting light.

[0004] For example, CN221272778U discloses a three-dimensional logo light for automobiles, including a lamp housing with a cavity, a logo installed at the opening end of the housing, and a light source disposed within the cavity of the lamp housing. The logo has a hollowed-out area and also includes a light-transmitting mirror. The light-transmitting mirror includes a light-transmitting area corresponding to the shape of the logo and a non-light-transmitting area corresponding to the hollowed-out area of ​​the logo. The logo is located above the light-transmitting mirror and is fixedly attached to the light-transmitting area of ​​the light-transmitting mirror. The edge of the light-transmitting area in the light-transmitting mirror is exposed along the edge of the non-hollowed-out area of ​​the logo. The light source is located below the light-transmitting mirror. This solution presents a linear luminous effect when the logo light is lit at night, making the logo pattern more three-dimensional.

[0005] However, the common light-emitting forms of these exterior ambient lights are either all-over illumination or frontal illumination, resulting in a direct and singular lighting effect that fails to meet the diverse lighting needs of the market, leading to a lack of market competitiveness. In contrast, exterior ambient lights that can emit light only from the side and not from the front can provide a sense of floating for the displayed signage. However, due to the complex structure and high manufacturing difficulty of side-emitting exterior lights, there is currently no mature technology that can achieve side-emitting only for the current application scenarios. Utility Model Content

[0006] The purpose of this invention is to solve at least one of the aforementioned problems by providing a three-dimensional luminous decorative component and automobile with a floating effect, thereby addressing the issue that existing luminous decorative components can only emit light from the front or the entire surface, resulting in a single luminous effect. This solution, while meeting the optical property requirements such as brightness and uniformity of the exterior ambient lighting, provides a floating appearance effect for the logo to be displayed on the luminous decorative component.

[0053] The lamp assembly includes a lamp housing 5, a lamp shade 8, a light source 13, a circuit board 14, a reflector 10, a heat sink 11, a waterproof and breathable membrane 12, and a wiring harness connector 9. The lamp assembly is assembled to the inside of the decorative panel 1 via the lamp housing 5. The lamp shade 8 is assembled to the lamp housing 5 by laser welding, forming a closed inner cavity between the lamp shade 8 and the lamp housing 5. The light source 13, the circuit board 14, the reflector 10, and the heat sink 11 are disposed inside the inner cavity. The waterproof and breathable membrane 12 and the wiring harness connector 9 are respectively installed on the lamp housing 5 and are used for ventilation and wiring of the inner cavity, respectively. Specifically, the circuit board 14 is located in the middle of the inner cavity and fixed to the lamp housing 5 with screws. The light source 13 is electrically connected to the circuit board 14, and the light source 13 is positioned towards the lamp cover 8. The heat sink 11 is attached to the circuit board 14 to dissipate heat. The reflector 10 is positioned between the light source 13 and the lamp cover 8, and several reflectors 10 can be spaced apart according to the light emission performance requirements to achieve the target light emission effect. Figure 1 As shown, in this embodiment, the circuit board 14 is an integrated circuit board (PCBA), the light source 13 is an LED light source, the reflector 10 is an ABS reflector bowl, the heat sink 11 is a heat sink, the lampshade 8 is a pure transparent PMMA lampshade, and the lamp housing 5 is a PC+ABS material housing. The circuit board 14 is arranged along the length of the inner cavity. The light source 13 is connected to the side of the circuit board 14 facing the lampshade 8. The heat sink 11 is attached to the side of the circuit board 14 facing away from the lampshade 8, and thermal grease is applied between the heat sink 11 and the circuit board 14 to form a thermally conductive layer to help accelerate heat transfer.

In other embodiments, the lamp housing 5 may also be made of other similar materials that can achieve the same optical and process requirements, and the reflector may also be made of materials such as PC+ABS that can achieve the same optical and process requirements.

[0054] The sign assembly includes sign component 7, such as Figure 1As shown, in this embodiment, the identification member 7 is made of milky PMMA material. A foam 4 is adhered to the edge position of the inner surface (the surface facing the lamp cover 8) of the identification member 7 through a first adhesive layer 3, and a second adhesive layer 6 for bonding the decorative plate 1 is provided on the outer surface (the surface facing away from the lamp cover 8) of the identification member 7 to bond and fix the identification member 7 to the inner side of the decorative plate 1. Moreover, a protrusion 16 for forming an identification shape is provided on the outer surface of the identification member 7, and a non-light-emitting area 17 is provided at the end of the protrusion 16 so that when light passes through, only the side surface of the protrusion 16 part emits light and the front surface does not emit light. The identification that the protrusion 16 part of the identification member 7 can form includes but is not limited to characters, symbols, patterns, logos, and brand logos; in this embodiment, the protrusion 16 part of the identification member 7 forms a word mark. Both the first adhesive layer 3 and the second adhesive layer 6 use 3M back glue, and the foam 4 also has 3M back glue. In other embodiments, the identification member can also be made of materials such as PC that can achieve the same optical and process requirements.

[0055] The decorative plate 1 is an outer decorative plate 1, and an opening (laser cutting hole) for passing through the protrusion 16 part of the identification member 7 is provided thereon. The thickness of the protrusion 16 of the identification member 7 should be greater than the thickness of the decorative plate 1 + the second adhesive layer 6, so that the protrusion 16 part protrudes from the surface of the decorative plate 1. The inner surface of the decorative plate 1 is adhesively fixed to the identification member 7 through the second adhesive layer 6. Moreover, a bracket 2 is provided at a position near the edge of the decorative plate 1, and the lamp housing 5 of the lamp body assembly is fixedly connected to the decorative plate 1 through the bracket 2 (specifically, the lamp housing 5 and the bracket 2 are fastened and fixed by a fastener 15), so that the decorative plate 1 can press and fit the identification member 7 of the identification assembly tightly against the outer surface of the lamp cover 8. At this time, the foam 4 is squeezed and fitted between the lamp cover 5 and the identification member 7, playing a certain buffering role and dustproof and waterproofing the inside of the light-emitting decorative part. In this embodiment, the decorative plate 1 is made of an opaque material of PC + ABS, and the fastener 15 is a screw.

[0056] The non-light-emitting area 17 at the top of the protrusion 16 can be formed by methods such as hot stamping, physical vapor deposition (PVD), electroplating, electroforming, in-mold insert molding (IML), etc. The specific material selected can be determined according to the optical effect to be shown in the design.

[0057] Such as Figure 2 As shown, it is a hot stamping layer (non-light-emitting area 17) formed on the top of the protrusion 16 by hot stamping. Specifically: the top of the protrusion 16 is provided in a form of a rounded corner transition, or in a form of an arc surface. The hot stamping layer formed by hot stamping has a "冖" - shaped structure, and the hot stamping layer extends and covers to a position half of the R corner to block the light path emitted from the front, so that the light can only be emitted from the side surface of the protrusion 16 of the identification member 7 that exceeds the decorative plate 1.

[0058] Such as Figure 3As shown, it is a deposited layer (non-light-emitting area 17) formed by PVD, which is usually used for the light-emitting decorative parts on the A surface of the vehicle. Specifically: The top of the protrusion 16 is set in the form of a rounded corner transition, or in the form of an arc surface. The deposited layer formed by PVD has a "冖" - shaped structure, and this deposited layer extends and completely covers the arc part to block the light path emitted from the front, so that the light can only be emitted from the side of the protrusion 16 of the identification part 7 that exceeds the trim panel 1. This deposited layer is composed of an inner black paint layer (used for light absorption and blocking the light path) and an outer metal film layer (used for protecting the black paint layer and having a decorative effect).

[0059] As Figure 4 shown, it is an in-mold insert injection layer (non-light-emitting area 17) formed by IML. Specifically: The top of the protrusion 16 is set in the form of a rounded corner transition, or in the form of an arc surface. The in-mold insert injection layer formed by IML (a film, and the insert therein is opaque) has a "冖" - shaped structure, and this in-mold insert injection extends and completely covers the arc part to block the light path emitted from the front, so that the light can only be emitted from the side of the protrusion 16 of the identification part 7 that exceeds the trim panel 1.

[0060] As Figure 5 shown, it is an electroformed layer (non-light-emitting area 17) formed by electroforming. Specifically: Due to process reasons, the electroformed layer itself has a certain thickness, so it can be directly formed on the end face of the top of the protrusion 16 and has a good effect of blocking the front light emission.

[0061] As Figure 6 、 7 shown, it is an electroplated layer (non-light-emitting area 17) formed by electroplating. Specifically: According to different electroplating methods, it can be further divided into: 1) Two-color injection molding + electroplating. For the identification part 7, or only the protrusion 16 part of the identification part 7 uses the two-color injection molding method, so that the electroplating material is formed at the end position of the protrusion 16, and then an electroplated layer is formed on the electroplating material by electroplating. The top of the protrusion 16 is set in the form of a rounded corner transition, or in the form of an arc surface, and this electroplated layer has a "冖" - shaped structure, extends and completely covers the arc part to block the light path emitted from the front, so that the light can only be emitted from the side of the protrusion 16 of the identification part 7 that exceeds the trim panel 1. 2) Selective electroplating. Only a layer of electroplating material layer with a certain thickness is formed on the end face of the protrusion 16 part, and an electroplated layer with a "冖" - shaped structure is formed on it by electroplating, which extends and completely covers the electroplating material layer to block the light path emitted from the front, so that the light can only be emitted from the side of the protrusion 16 of the identification part 7 that exceeds the trim panel 1.

[0062] As Figure 8 shown, it is another deposited layer (non-light-emitting area 17) formed by PVD, which is the same as Figure 3The main structural difference shown is that the protrusion 16 is hollow inside, which can reduce the amount of material used and reduce the weight to a certain extent.

[0063] The processing techniques described above, such as hot stamping, physical vapor deposition (PVD), electroplating, electroforming, and in-mold injection molding (IML), can all be performed using existing technologies. This solution does not improve the processes.

[0064] When using the luminous decorative component of this embodiment:

[0065] When not lit, the front of the sign formed by the sign component 7 has a metallic appearance effect of the non-luminous area 17 formed by hot stamping, PVD, electroplating and other treatments, while the side has a milky white PMMA appearance effect of the raised part 16 of the sign component 7.

[0066] After being lit, the light emitted from the LED light source is focused by the reflector bowl, passes through the pure transparent PMMA lampshade 8, and shines on the back of the milky white PMMA sign 7. Because the raised part 16 on the front of the sign 7 has been treated by hot stamping, PVD or electroplating, it is opaque. At this time, the front of the sign 7 still has a metallic appearance, while the side emits light, presenting a high-intensity light effect, making the sign shape formed by the non-light-emitting area 17 of the sign 7 have a floating effect.

[0067] The above description is only a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various changes can be made to the above embodiments of this utility model to meet the design requirements of the light emission effect. For example, the reflector 10 (reflector bowl) of this solution is arranged between the lampshade 8 and the light source 13. In other applications, the reflector bowl can be arranged at any angle, direction, and position according to the shape and structural requirements, and the number and shape can also be changed arbitrarily. It can be a combination of multiple different reflectors 10. The materials of the sign 7, the lampshade 8, and the reflector bowl in this case are milky white PMMA, pure transparent PMMA, and white ABS, respectively. In different applications, the materials can also be the same material of different colors or different materials that can achieve a unified optical purpose. The light source 13 of this solution uses red LED particles. In other applications, any light source of any color can be selected according to regulatory restrictions and appearance requirements. The non-light-emitting area 17 on the front of the light-emitting component of this solution adopts a metallic appearance effect. In other applications, it can also be any color or any other appearance effect. Furthermore, the logo displayed by the luminous decorative component of this utility model adopts a word mark, which can contain any text or symbol content. In other embodiments, it can also be any pattern, emblem, or brand logo. That is, all simple and equivalent changes and modifications made in accordance with the claims and description of this utility model fall within the protection scope of the claims of this utility model. Any aspects not described in detail in this utility model are conventional technical content.
