Description

Technical Field

[0001] The present invention relates to the field of vehicle parts, and in particular to a decorative part and glass assembly for a vehicle. Background Art

[0002] Currently, the luminous structure of mainstream automotive metal exterior parts uses a light source plus a light guide plate or a light guide body and is arranged inside the metal parts. The luminescence of the metal exterior parts is achieved by opening holes / grooves on the metal exterior parts.

[0003] However, existing light-emitting structures of metal exteriors have the following drawbacks: 1. Because the metal exteriors must integrate light sources, light guide plates, or light guide bodies, high internal space requirements are imposed on the metal exteriors. In actual applications, the internal space of metal exteriors is often affected by the product's own internal structure or function, making the design of integrated light source circuits and light guide bodies difficult. Furthermore, the matching precision between existing metal exteriors and light guide plates or light guide bodies is not high, resulting in poor lighting effects. 2. Because light guides or light guide plates can be embedded in openings or slots in metal exteriors, high matching precision requirements are imposed on the light guides and the light-transmitting holes / slots of the metal exteriors. (A small gap between the light guide and the light-transmitting hole / slot will affect assembly operations or damage the light guide, while a large gap will affect the overall appearance of the metal exterior.) Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a decorative part and glass assembly for a vehicle, which improves the luminous effect of metal exterior decorative parts and reduces the difficulty of production.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A decorative part for a vehicle, comprising a decorative part body, a flexible luminous body and a light-transmitting part;

[0007] The flexible luminous body is attached to the inner side of the decorative part body;

[0008] The decorative part body has a plurality of light-transmitting through holes, and the plurality of light-transmitting through holes form a light-emitting area outside the decorative part body;

[0009] The light-transmitting member is located between the decorative member body and the flexible light-emitting body, and is used to generate light effects in the light-emitting area.

[0010] In order to solve the above technical problems, another technical solution adopted by the present invention is:

[0011] A glass assembly includes the above-mentioned decorative component.

[0012] The beneficial effects of the present invention are as follows: since the inner surface of the decorative body is typically curved, the flexible luminous body conforms to the inner side of the decorative body, reducing the viewing angle between the light path originating from the flexible luminous body and the axis of the light-transmitting through hole, thereby achieving the purpose of improving the lighting effect, ensuring that all light emitted by the flexible luminous body can pass through the light-transmitting through hole, and achieving the optimal lighting effect of the luminous area. In addition, the use of a flexible luminous body can match the complex curved surface and confined space inside the decorative body. Compared with flat luminous bodies, the assembly method using a flexible luminous body makes assembly easier. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0025] Please refer to Figure 2 as well as Figure 7, a decorative part for a vehicle, comprising a decorative part body, a flexible luminous body and a light-transmitting part;

[0026] The vehicles include vehicles, trains, aircraft, marine vehicles, etc.

[0027] The flexible luminous body is attached to the inner side of the decorative part body;

[0028] The decorative part body has a plurality of light-transmitting through holes, and the plurality of light-transmitting through holes form a light-emitting area outside the decorative part body;

[0029] The light-transmitting member is located between the decorative member body and the flexible light-emitting body, and is used to generate light effects in the light-emitting area.

[0030] The working principle of the present invention is:

[0031] The use of a flexible light-emitting body improves the fit between the light-emitting body and the inner side of the ornament body, reduces the difficulty of production, and narrows the viewing angle formed between the light path and the axis of the light-transmitting through hole, thereby improving the lighting effect.

[0032] As can be seen from the above description, the beneficial effects of the present invention are as follows: since the inner surface of the decorative body is usually curved, the flexible light-emitting body is fitted to the inner side of the decorative body, which reduces the visual angle between the light path originating from the flexible light-emitting body and the axis of the light-transmitting hole, thereby achieving the purpose of improving the lighting effect, ensuring that all light emitted by the flexible light-emitting body can pass through the light-transmitting hole, and optimizing the lighting effect of the light-emitting area. In addition, the use of a flexible light-emitting body can match the complex curved surface and narrow space inside the decorative body. Compared with flat light-emitting bodies, the assembly method using a flexible light-emitting body makes assembly easier.

[0033] Furthermore, the light-transmitting member has plasticity;

[0034] A light guide groove is provided on the inner side of the decorative part body and is connected to the plurality of light-transmitting through holes;

[0035] One end of the light-transmitting member away from the flexible light-emitting body is filled in the light-transmitting through hole, and one end of the light-transmitting member close to the flexible light-emitting body is filled in the light-guiding groove.

[0036] From the above description, it can be seen that a light guide groove is provided and the two ends of the light-transmitting part are respectively filled in the light guide groove, so as to improve the connection strength between the light-transmitting part and the ornament body, and improve the sealing of the light-transmitting through hole to prevent dust from entering; at the same time, the provision of a light guide groove can shorten the depth of the light-transmitting through hole to avoid the defect of poor light transmission effect caused by excessive absorption of light by the wall of the light-transmitting through hole in the light-transmitting through hole, thereby improving the luminous effect of the ornament.

[0037] Furthermore, the light-transmitting member is UV transparent adhesive.

[0038] From the above description, it can be seen that since UV transparent glue has the advantages of anti-aging, UV protection, and good light transmittance, using UV transparent glue as a light-transmitting part can extend the service life of the ornament body and ensure the sealing and light transmittance of the ornament body.

[0039] Furthermore, the ratio of the depth of the light-guiding groove in the axial direction of the light-transmitting through hole to the thickness of the decorative component body in the axial direction of the light-transmitting through hole is 1:2 to 0.6:1.

[0040] From the above description, it can be seen that the ratio of the depth of the light guide groove to the thickness of the ornament body is 1:2~0.6:1, that is, the ratio of the thickness of the light guide groove to the circumferential length of the light-transmitting hole is 1:1~2:3. At this ratio, the light transmission effect can be enhanced.

[0041] Furthermore, the light path generated by the flexible light-emitting body is parallel to the axis of the light-transmitting through hole.

[0042] From the above description, it can be seen that the light path generated by the flexible light-emitting body is parallel to the axis of the light-transmitting hole, which can achieve the optimal lighting effect. Compared with the existing technology, the lighting effect is softer, more uniform and has a certain three-dimensional effect.

[0043] Furthermore, the plurality of light-transmitting through holes are evenly distributed.

[0044] It can be seen from the above description that the multiple light-transmitting through holes are evenly distributed to ensure the luminous effect of the luminous area.

[0045] Furthermore, the inner diameter of the light-transmitting through hole is 0.5 mm to 0.8 mm.

[0046] It can be seen from the above description that when the inner diameter is within this numerical range, the light transmission effect of the light-transmitting through hole reaches an optimal level.

[0047] Furthermore, the flexible light-emitting body is bonded to the inner side of the ornament body.

[0048] As can be seen from the above description, the flexible light-emitting body is connected to the ornament body by bonding, which is convenient for assembly.

[0049] Furthermore, the flexible light-emitting body is an electroluminescent component.

[0050] Another technical solution adopted in the present invention is:

[0051] A glass assembly includes the above-mentioned decorative component.

[0052] Comparative Example 1:

[0053] Figure 1This is a diagram of the light path of an ornament in the prior art. Since the surface of the ornament is usually not completely flat due to the requirements of the shape, when a light guide is used to transmit and emit light, the ornament has the defect of poor lighting effect due to the light path being partially blocked in the micropores.

[0054] Example 1

[0055] Reference Figure 2-Figure 6 A decorative part for a vehicle includes a decorative part body 1, a flexible luminous body 2, and a light-transmitting part 3; the flexible luminous body 2 is attached to the inner side of the decorative part body 1; the decorative part body 1 has a plurality of light-transmitting through holes 11, and the plurality of light-transmitting through holes 11 form a light-emitting area 12 on the outer side of the decorative part body 1; the light-transmitting part 3 is located between the decorative part body 1 and the flexible luminous body 2 to generate light effects in the light-emitting area 12. Compared with comparative example 1 (such as Figure 1 As shown in FIG. , this embodiment utilizes a flexible light-emitting element 2 to improve the fit between the light-emitting element and the inner side of the decorative body 1, thereby improving the lighting effect and reducing production difficulties. Optionally, the decorative body 1 can be made of metal or plastic, with metal being aluminum or stainless steel, and plastic being PET or PC. In this embodiment, the decorative body 1 is preferably made of metal.

[0056] Example 2

[0057] Reference Figure 2-Figure 7 , a decorative part for a vehicle, based on the first embodiment, a light-guiding groove 13 is provided on the inner side of the decorative part body 1, which is connected to a plurality of light-transmitting through holes 11 at the same time; the light-transmitting part 3 has plasticity, which can achieve the effect of improving the sealing performance, and the end of the light-transmitting part 3 away from the flexible light-emitting body 2 is embedded in the light-transmitting through hole 11, and the end of the light-transmitting part 3 close to the flexible light-emitting body 2 is filled in the light-guiding groove 13. In order to ensure that the lighting effect reaches the optimal level, the light-emitting area 12 of the decorative part body 1 is thinned so that the inner diameter of the light-transmitting through hole 11 reaches 0.5mm~0.8mm, and the light-guiding groove 13 is opened on the inner side of the light-emitting area 12 after the thinning treatment. Optionally, the ratio of the depth of the light-guiding groove in the axial direction of the light-transmitting through hole to the thickness of the decorative part body in the axial direction of the light-transmitting through hole is 1:2~0.6:1. Preferably, the thickness ratio is 1:2.

[0058] Preferably, the light-transmitting member 3 is UV transparent adhesive. Because the prior art provides corresponding light-transmitting holes or grooves on the surface of exterior trim, there will be a certain gap or unevenness between the light-transmitting member and the light-transmitting hole or groove. In actual use, this can easily cause dust accumulation on the surface of the exterior trim (dust or dirt remaining in the gap or unevenness, affecting the appearance). Furthermore, the gap between the exterior trim and the light-transmitting member prevents a waterproof seal, allowing rainwater to easily enter the interior of the exterior trim. Even if a waterproof seal is provided within the integrated light source LED and integrated circuit, prolonged rainwater penetration will affect the service life of the electronic components. Therefore, in this embodiment, the light-transmitting member is filled in the following manner: before the sealing treatment, the light-transmitting through hole 11 is sprayed with a primer (i.e., UV transparent glue), the fluidity of the UV transparent glue is used to fill the light-transmitting through hole 11, UV irradiation is used to solidify the UV transparent glue, and then the UV transparent glue is filled in the light guide groove 13, and UV irradiation is performed again to solidify the UV transparent glue, thereby improving the sealing and waterproof properties of the light-transmitting through hole 11, avoiding dust accumulation, and thus extending the service life, and improving the matching accuracy between the light-transmitting member 3, the light guide groove 13 and the light-transmitting through hole 11, thereby improving the luminous effect.

[0059] Reference Figure 5 The light path generated by the flexible light-emitting element 2 is parallel to the axis of the light-transmitting through hole 11. Because the inner and outer surfaces of current automotive metal trims are both uneven, placing a flat, rigid light-emitting element inside the trim body would result in a large visible angle between the light path and the axis of the light-transmitting through hole 11, resulting in poor lighting performance. In this embodiment, a flexible light-emitting element 2 is provided, and its light path is parallel to the axis of the light-transmitting through hole 11, minimizing light loss during propagation and ensuring optimal lighting performance.

[0060] Preferably, the plurality of light-transmitting through holes 11 are evenly distributed, so that the light emitted by the light-emitting area 12 is more uniform.

[0061] Reference Figure 5 The flexible luminous body 2 is bonded to the inner side of the decorative body 1. Specifically, the flexible luminous body 2 is bonded to the inner side of the decorative body 1 by a colloid 4. Preferably, the colloid 4 is 3M glue.

[0062] Optionally, the flexible light-emitting body 2 is an electroluminescent component or an LED board; preferably, the flexible light-emitting body 2 is an electroluminescent component.

[0063] Reference Figure 7When the flexible light-emitting body 2 is an electroluminescent component, the flexible light-emitting body 2 includes a first PET protective layer 21, a transparent conductive layer 22, a light-emitting layer 23, an insulating layer 24, an electric coal layer 25, and a second PET protective layer 26; the first PET protective layer 21, the transparent conductive layer 22, the light-emitting layer 23, the insulating layer 24, the electric coal layer 25, and the second PET protective layer 26 are stacked in sequence; the first PET protective layer 21 is arranged toward the decorative part body 1. The electric coal layer 25 is electrically connected to the external power supply via a cable 27. Preferably, the flexible light-emitting body 2 is integrally packaged. In this embodiment, since the electroluminescent component is integrally packaged after being stacked with multiple layers of materials, the electroluminescent component has good flexibility and can fit tightly with the decorative part body 1, so that the light generated by the light-emitting layer 23 passes through the transparent conductive layer 22 and the first PET protective layer 21 in sequence and then enters the light-transmitting through hole 11, making the lighting effect softer and having a certain three-dimensional effect.

[0064] Example 3

[0065] A glass assembly includes the decorative parts described in the first and second embodiments.

[0066] The glass assembly in this embodiment includes a glass plate and a rim arranged around the glass plate; and the decorative component is mounted on the rim.

[0067] The decorative parts in the present invention are preferably arranged on the corner window glass assembly, but it is easy to understand that in other embodiments of the present invention, the decorative parts can also be used in the A-pillar, B-pillar, C-pillar and other positions of the automobile, and can also be used in any position of the automobile exterior decorative parts such as the vehicle's luggage rack, water cut and door frame trim. As a preferred embodiment, the present invention can also be used on the interior decoration of the automobile.

[0068] In summary, the present invention provides a vehicle trim and glass assembly that creates a luminous area on the surface of the trim body by providing multiple evenly distributed light-transmitting holes. The flexible electroluminescent component conforms more closely to the inner curved surface of the trim body, reducing assembly difficulty and making the light formed in the luminous area softer, more uniform, and more three-dimensional, improving the user's sensory experience. The light-transmitting element utilizes UV transparent adhesive, which is then cured by UV irradiation after filling the light-transmitting holes and light guide grooves with liquid. This ensures a luminous effect while improving the sealing of the light-transmitting holes and providing a waterproof effect.

Any equivalent transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
