Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to a front bumper upper decorative part, a light-emitting car logo structure having the front bumper upper decorative part, and a vehicle having the light-emitting car logo structure. Background Technology

[0002] The sign uses transparent PC material, with the logo area on the inner surface sprayed with white translucent paint. This type of technical solution results in a white logo pattern whether it is illuminated or not under natural light, with only differences in brightness. Especially under direct sunlight, it gives the visual effect of being indistinguishable from an illuminated sign. Furthermore, many logo areas are separated into independent parts, and the logo pattern is formed by spraying paint or PVD process. The back of the logo area is assembled with the light source, and then assembled with the decorative outer panel 1 or bumper, resulting in a noticeable installation gap. Due to manufacturing tolerances, the gap is uneven, resulting in poor consistency. Different vehicles have gaps that are larger or smaller, which easily accumulates dust and leads to customer complaints. It is also difficult to match different patterns, indicating room for improvement. Utility Model Content

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0032] The following is for reference. Figures 1-3 The front bumper upper decorative part 100 according to an embodiment of the present utility model is designed to be dark when the car logo light source 2 is not illuminated by the car logo light source 2, so that the hollow car logo 121 appears dark. It can also be white when the car logo light source 2 is illuminated by the car logo light source 2, so that the hollow car logo 121 appears white. This design shows the different colors of the hollow car logo 121. The design is ingenious and easy for users to observe. Furthermore, the hollow car logo 121 can be engraved on the hollow layer 12, which can provide a variety of hollow car logo 121 patterns and make the production more flexible.

[0033] like Figures 1-3 As shown, the front bumper upper decorative part 100 according to an embodiment of the present utility model includes: decorative part outer panel 1.

[0034] The outer panel 1 of the decorative part includes a transparent substrate 11, a hollow layer 12 and a light-transmitting paint layer 13. The transparent substrate 11, the hollow layer 12 and the light-transmitting paint layer 13 are stacked in sequence along the illumination direction of the car logo light source 2. The hollow layer 12 is engraved with a hollow car logo 121. The transparent substrate 11 is constructed to appear dark when the car logo light source 2 is not illuminated.

[0035] It should be noted that the upper front bumper trim 100 is located on the front side of the vehicle's front bumper, and the upper front bumper trim 100 also includes an inner panel. The outer trim panel 1 is located on the outside of the inner panel and is connected to the inner panel. The outer trim panel 1 can be bonded to the inner panel, or it can be connected by welding, snap-fitting, screwing, etc., and the outer trim panel 1 can be directly connected to the vehicle body structure.

[0036] Specifically, the transparent substrate 11 is the main structure of the outer panel 1 of the decorative part, which can be used to realize the decorative function of the front of the vehicle body. The transparent substrate 11, the hollow layer 12 and the light-transmitting paint layer 13 are stacked in sequence along the irradiation direction of the car logo light source 2. The irradiation direction of the car logo light source 2 can be set to irradiate longitudinally along the vehicle from the inside to the outside. In this way, the transparent substrate 11, the hollow layer 12 and the light-transmitting paint layer 13 can be arranged to be distributed from back to front. The hollow layer 12 and the light-transmitting paint layer 13 cover the outer surface of the transparent substrate 11 in sequence and are stacked with each other by spraying paint. The spraying method is uniform, which can make the overall external structure of the outer panel 1 of the decorative part smooth and flat, and the body color consistent. At the same time, different coloring effects can be achieved according to the vehicle type.

[0037] Furthermore, the hollow layer 12 is used for the production of the hollow car logo 121, which displays the car logo to represent different vehicle brands. In actual processing, laser engraving can be performed using processing equipment such as laser engraving machines. The hollow car logo 121 can be engraved on the hollow layer 12, meaning it can be engraved on the outside of the transparent substrate 11, thus achieving the production of the hollow car logo 121 with high engraving precision. Compared to the separate hollow car logo 121, the hollow car logo 121 is integrally formed with the transparent substrate 11, meaning there are no installation gaps. The hollow car logo 121 can be used as an identifier for various types of vehicles, and its processing method is simple and its application range is wide.

[0038] Therefore, the above-mentioned arrangement does not damage the structure of the transparent substrate 11, reduces the processing difficulty and saves processing time, and ensures the integrity of the transparent substrate 11 structure. Furthermore, a translucent paint layer 13 is coated on the outside of the hollowed-out logo 121, which allows the hollowed-out logo 121 to be hidden inside the translucent paint layer 13, making the hollowed-out logo 121 an integral part of the decorative outer panel 1. Moreover, there is no protrusion at the hollowed-out logo 121, which reduces the adverse effect of the protruding logo on wind resistance, thereby reducing energy consumption and improving fuel economy.

[0039] In actual use, the transparent substrate 11 can appear dark when the car logo light source 2 is not irradiated, that is, the hollow car logo 121 can appear dark, and it can appear white when the car logo light source 2 is irradiated, that is, the hollow car logo 121 can appear white. In this way, the different color display effects of the hollow car logo 121 are reflected, making it easy to observe whether the hollow car logo 121 is in a light-emitting state.

[0040] The transparent substrate 11 can be made of PP luminescent material, which is a composite material. Carbon black master particles can be mixed into the milky white diffused PP particles, so that the transparent substrate 11 presents a textured dark or black effect when it does not emit light, and when it emits light, the car logo light source 2 presents a milky white luminescent effect through the transparent substrate 11 and the hollowed-out car logo 121.

[0041] According to the embodiment of this utility model, the upper front bumper decorative part 100 can make the transparent substrate 11 appear dark when the car logo light source 2 is not illuminated, so that the hollow car logo 121 appears dark. It can also make the transparent substrate 11 appear white when the car logo light source 2 is illuminated, so that the hollow car logo 121 appears white. This can create a strong contrast between the hollow car logo 121 when it is not emitting light and when it is emitting light, making it easy for users to identify whether the hollow car logo 121 is emitting light. It reflects different colors of the hollow car logo 121. Its design is ingenious and easy for users to observe. Moreover, the hollow car logo 121 is engraved on the hollow layer 12. Compared with the traditional method of installing the hollow car logo 121 on the outer plate 1 of the decorative part, setting the hollow car logo 121 to be hidden inside the outer plate 1 of the decorative part can reduce the installation gap between the two and protect against dust and other impurities. The effect is better and it can provide a variety of hollow car logo 121 patterns, such as different patterns, other light strips or text, etc., making the production more flexible.

[0042] In some embodiments, the perforated layer 12 includes a first primer layer 122 and a body color layer 123 that are sequentially distributed along the illumination direction of the vehicle logo light source 2.

[0043] Specifically, the perforated layer 12 is a paint layer, which includes a first primer layer 122 and a body color layer 123. The first primer layer 122 and the body color layer 123 are sequentially sprayed onto the outside of the transparent substrate 11 along the irradiation direction of the car logo light source 2. The first primer layer 122 is the bottom layer and is usually used to increase the adhesion between the coating and the car body, prevent rust, and provide a good base for the upper coating. The body color layer 123 is a color paint layer, which is located on top of the first primer layer 122. It provides the car with the required color and has certain corrosion resistance, weather resistance, and crack resistance. The first primer layer 122 can be black, and the body color layer 123 can be white, black, yellow, blue, red, etc. In this way, by applying at least two layers of paint, the surface of the decorative outer panel 1 can be colored, which plays a certain decorative role and makes the surface of the decorative outer panel 1 smooth. The paint has strong adhesion and can protect the transparent substrate 11 to reduce direct wear and scratches to the transparent substrate 11.

[0044] In other embodiments, the translucent paint layer 13 includes a second primer layer 131, which is sprayed onto the perforated layer 12 to hide the perforated car logo 121 of the perforated layer 12. The second primer layer 131 has light-transmitting properties, allowing light to pass through, so as to achieve the color display effect of the perforated car logo 121. The second primer layer 131 can increase the adhesion between the first primer layer 122, the body color layer 123 and the translucent paint layer 13, and improve the surface flatness of the outer panel 1 of the decorative part.

[0045] Furthermore, the hollow layer 12 is set as the first primer layer 122 and the body color layer 123, so that the hollow car logo 121 can be engraved on the paint layer. It can be adapted to different body color paints. The outer side of the hollow car logo 121 is sprayed with a second primer layer 131, which can hide the hollow car logo 121 inside the translucent paint layer 13. There is no protrusion at the hollow car logo 121, which reduces the adverse effect of the protruding car logo on wind resistance and improves the vehicle's economy.

[0046] In some embodiments, the paint color depth of the second primer layer 131 is less than that of the first primer layer 122.

[0047] Specifically, the second primer layer 131 is set to a lighter color, while the first primer layer 122 is set to a darker color. Darker paint usually contains more pigment particles and absorbs light more strongly, while lighter colors have the opposite effect. That is, the first primer layer 122 has strong hiding power and better light absorption, and the second primer layer 131 has low hiding power and weak light absorption, thus achieving light transmission.

[0048] Furthermore, the body color layer 123 is located beneath the second primer layer 131. This ensures that the second primer layer 131 does not obscure the paint color of the body color layer 123, allowing the vehicle to display its color normally. The second primer layer 131 also protects the paint of the body color layer 123, reducing wear and tear and extending its lifespan. Additionally, it improves the surface smoothness of the outer trim panel 1. Moreover, the darker color of the first primer layer 122 effectively blocks the color of the transparent substrate 11. The body color layer 123 is then applied over the first primer layer 122, allowing the outer trim panel 1 to display the color of the body color layer 123 and enhancing the saturation of the body color.

[0049] The second primer layer 131 can be set to be a transparent primer.

[0050] In some embodiments, the perforated layer 12 further includes a first clear coat layer 124 located on the side of the body color layer 123 opposite to the first primer layer 122.

[0051] Specifically, by setting the color of the first clear varnish layer 124 to be lighter, the light transmittance of the first clear varnish layer 124 can be increased, while the opacity of the first clear varnish layer 124 can be reduced. Figure 1 As shown, the first clear coat layer 124 is located on the side of the body color layer 123 away from the first primer layer 122. In this way, the first clear coat layer 124 will not block the color of the body color layer 123, so that the vehicle can display its color normally. The first clear coat layer 124 can increase the adhesion between the first primer layer 122 and the body color layer 123, protect the paint of the body color layer 123, reduce the wear of the body color layer 123, improve the service life of the paint of the body color layer 123, and improve the surface smoothness of the outer panel 1 of the decorative part.

[0052] In some other embodiments, the translucent varnish layer 13 further includes a second clear varnish layer 132 located on the second primer layer 131 away from the perforated layer 12.

[0053] Specifically, by setting the second clear coat 132 to a lighter color, the light transmittance of the second clear coat 132 can be achieved, while reducing the opacity of the second clear coat 132 itself and its coverage of the first clear coat 124. Figure 1 As shown, the second clear coat layer 132 is located on the side of the second primer layer 131 away from the perforated layer 12. In this way, the second clear coat layer 132 will not block the color of the body color layer 123 and the perforated logo 121, so that the vehicle can display its color normally and the perforated logo 121 can shine normally. The second clear coat layer 132 can also protect the paint of the body color layer 123 and the perforated logo 121, reduce the wear of the body color layer 123, improve the service life of the paint of the body color layer 123, and improve the surface smoothness of the outer panel 1 of the decorative part.

[0054] Furthermore, by providing a second primer layer 131 and a second clear coat layer 132 on the outside of the hollowed-out layer 12, the surfaces of the hollowed-out logo 121 and the body color layer 123 can be made brighter and more transparent, improving the overall effect and texture of the decorative outer panel 1.

[0055] In some embodiments, the hollowed-out car logo 121 sequentially penetrates the first primer layer 122, the body color layer 123, and the first clear coat layer 124 along the illumination direction of the car logo light source 2.

[0056] Specifically, the hollowed-out logo 121 is set through the first primer layer 122, the body color layer 123, and the first clear coat layer 124. This allows the hollowed-out logo 121 to be set on three layers of paint without damaging the structure of the transparent substrate 11, i.e., no gaps are formed in the transparent substrate 11. By carving the hollowed-out logo 121 into the paint layer, the production of the hollowed-out logo 121 is simpler and more convenient. Moreover, the hollowed-out logo 121 is integrated into the paint layer. Compared with the traditional single-part logo, this embodiment can reduce the installation steps of the hollowed-out logo 121 and avoid the appearance of installation gaps on the outer panel 1 of the decorative part. This reduces the problem of low installation accuracy caused by irregular installation gaps and also avoids the problem of dust accumulation at the logo and customer complaints.

[0057] Therefore, as Figure 1 As shown, in actual production, a first primer layer 122, a body color layer 123, and a first clear coat layer 124 can be sequentially sprayed onto the upper surface of the transparent substrate 11. Then, a laser engraving machine is used to sequentially engrave the first clear coat layer 124, the body color layer 123, and the first primer layer 122 along the opposite direction of the light source 2. After engraving, a second primer layer 131 and a second clear coat layer 132 are sprayed onto the outside of the first clear coat layer 124 to complete the manufacturing process of the outer decorative panel 1. Finally, the outer decorative panel 1 is connected to the inner panel or the body. The manufacturing method is simple and convenient, and can simultaneously achieve multi-layer paint coating of the transparent substrate 11 and the production of the hollowed-out car logo 121.

[0058] In some embodiments, the outer panel 1 of the decorative component has a logo display area 14 and a non-logo display area 15, with the hollowed-out logo 121 located in the logo display area 14, and the first primer layer 122 located in the non-logo display area 15 being adapted to block the light from the logo light source 2.

[0059] Specifically, a large area of ​​the outer surface of the decorative panel 1 can be designated as a non-car logo display area 15 to cover structures inside the vehicle that do not need to be displayed, and it can also serve a decorative purpose. The central area of ​​the surface of the outer panel 1 can be designated as a car logo display area 14, in which a hollow car logo 121 is set in the car logo display area 14, which can make the position of the hollow car logo 121 more eye-catching. The hollow car logo 121 penetrates through the first primer layer 122, that is, there is no first primer layer 122 at the position of the hollow car logo 121, but there is a complete first primer layer 122 in the non-car logo display area 15, which can block the light emitted by the car logo light source 2 in the non-car logo display area 15.

[0060] In this way, when the hollow car logo 121 needs to emit light, the light emitted by the car logo light source 2 passes through the hollow car logo 121 to make the hollow car logo 121 emit light, and the light from the car logo light source 2 will not pass through the non-car logo display area 15, thereby reducing the light leakage phenomenon in the non-car logo display area 15 and realizing the effective illumination of the hollow car logo 121.

[0061] Therefore, the hollowed-out logo 121 can improve the logo's recognizability, and when the hollowed-out logo 121 is illuminated, it makes the logo more eye-catching and increases the brand recognition of the vehicle.

[0062] Furthermore, since the transparent substrate 11 uses a black-effect diffused PP material, to prevent light leakage in the non-car logo display area 15, which would cause faint light transmission around the hollowed-out car logo 121 and make the back car logo light source 2 visible, the first primer layer 122 is specially formulated. Requirements are placed on the median film thickness and upper and lower tolerances to ensure that the first primer layer 122 can still maintain its light-blocking effect even when the film thickness reaches the lower limit. Also, because different car body colors reflect laser energy differently, the laser power and laser engraving depth are adjusted for different car body colors. The degree and time are controlled and tolerances are defined to ensure that each body color layer 123 can be laser engraved reliably when the lower limit is reached, and to avoid dark areas when the paint and primer residues cause luminescence. In addition, since the substrate is diffused PP, the hollow car logo 121 only has a transparent primer and clear coat. By designing a special formula for the transparent primer, it is ensured that the surface clear coat and the transparent substrate 11 of the hollow car logo 121 have sufficient bonding strength, which can ensure that the scratch resistance, adhesion and other properties meet the requirements, thereby meeting the DVP requirements of the spraying performance.

[0063] This utility model also proposes a light-emitting car logo structure 101.

[0064] The luminous car logo structure 101 according to the present utility model includes a car logo light source 2 and a front bumper upper decorative part 100 of any of the above embodiments. The car logo light source 2 illuminates the side of the transparent substrate 11 away from the hollow layer 12.

[0065] In this way, when the car logo light source 2 emits light, the light shines on the inside of the transparent substrate 11, and the light can be transmitted through the transparent substrate 11 to the hollow layer 12, so that the hollow car logo 121 emits light.

[0066] Specifically, such as Figure 3 As shown, in the front-rear direction of the vehicle, the logo light source 2 is located behind the upper front bumper trim 100, that is, the logo light source 2 is located on the inner side of the vehicle. The upper front bumper trim 100 can protect the logo light source 2 and block it, preventing the logo light source 2 from being exposed outside the vehicle body. Furthermore, the light source side of the logo light source 2 can be positioned facing the perforated layer 12 of the transparent substrate 11. This allows the logo light source 2 to illuminate the perforated layer 12 when emitting light, reducing the light propagation path and enabling the light to quickly pass through the transparent substrate 11 to illuminate the perforated logo 121, thus achieving normal illumination of the perforated logo 121.

[0067] In some embodiments, the luminous car logo structure 101 further includes a light source cover 3, which covers the car logo light source 2, and at least a portion of the light source cover 3 is located between the decorative outer panel 1 and the car logo light source 2.

[0068] Specifically, the light source cover 3 is used to protect the vehicle logo light source 2, and the light source cover 3 is detachably connected to the vehicle body structure, such as... Figure 3 As shown, the light source cover 3 is installed outside the car logo light source 2, and at least a part of the light source cover 3 is located between the outer panel 1 of the decorative part and the car logo light source 2. The light source cover 3 can separate the car logo light source 2 from the outer panel 1 of the decorative part. The light source cover 3 can be connected to the outer panel 1 of the decorative part, and a sealed cavity can be formed between the two. This arrangement can hide the light source inside the light source cover 3, which can avoid the risk of water entering the light source and causing burning, and can maintain the normal light-emitting effect, thus improving the use effect of the hollow car logo 121.

[0069] Among them, the car logo light source 2 is hidden inside the outer panel 1 of the decorative part and is not visible to the outside. Through software control logic, it can be set to light up during the day along with the position lights, or it can be set to act according to the light sensor. It will not light up under strong light and will appear black. In the showroom and at night, it will light up as the ambient light decreases, thus improving the overall appearance of the vehicle.

[0070] The vehicle logo light source 2 can be integrated with the vehicle through light or set as a separate vehicle logo light source 2. The setting methods are diverse and can be flexibly selected.

[0071] In some embodiments, a sealing element 4 is provided between the outer panel 1 of the decorative element and the outer cover 3 of the light source. The sealing element 4 is annular in structure and extends around the hollowed-out car logo 121.

[0072] In this way, the area near the hollowed-out logo 121 can be sealed by the sealing element 4, which can prevent dust and other impurities from entering the inner side of the logo display area 14 of the transparent substrate 11, causing poor appearance quality problems such as dark areas or local particles on the inner surface of the hollowed-out logo 121, thereby improving the cleanliness of the hollowed-out logo 121 and the uniformity of the light-emitting surface.

[0073] Specifically, the seal 4 has certain elastic compression characteristics, such as Figure 3 As shown, the sealing element 4 is located between the outer panel 1 of the decorative element and the outer cover 3 of the light source. The sealing element 4 presses against the outer panel 1 of the decorative element and the outer cover 3 of the light source, so that there is no gap between the outer panel 1 of the decorative element and the outer cover 3 of the light source at the sealing element 4, thus achieving a seal between the outer panel 1 of the decorative element and the outer cover 3 of the light source. The sealing element 4 can be supported by materials such as rubber. For example, the sealing element 4 can be constructed as foam, and the gap between the outer panel 1 of the decorative element and the outer cover 3 of the light source is set to be equal to ensure that the foam and the outer cover 3 of the light source are interference fit, which can improve the sealing performance of the two.

[0074] And such as Figure 2 As shown, the foam structure is ring-shaped, and the ring-shaped foam extends around the outer periphery of the hollowed-out logo 121. This allows the outer panel 1 of the decorative part and the outer cover 3 of the light source to form a sealed space at the hollowed-out logo 121. This effectively prevents dust, water, and other impurities from entering the inner surface of the hollowed-out logo 121 and causing contamination. This also prevents impurities from blocking light, reducing black spots in the light emitted by the hollowed-out logo 121 and improving the uniformity of light emission. The structure is simple and the seal is reliable. Furthermore, since the outer panel 1 of the decorative part and the outer cover 3 of the light source are two independent parts, the wall thickness of the outer panel 1 can be set to a high precision, with tolerances controlled within ±0.05mm. This ensures that the light emitted by the logo light source 2 through the outer panel 1 is uniform, thus making the light emission of the hollowed-out logo 121 uniform.

[0075] It should be noted that the inner and outer surfaces of the transparent substrate 11 must remain smooth and flat within a 5mm area extending outward from the area of ​​the hollowed-out logo 121. Furthermore, the inner surface of the transparent substrate 11 must not have defects that affect the light-emitting effect, such as burrs, pores, bubbles, shrinkage, slider lines, or weld lines. The foam can be connected to the decorative outer panel 1 and the light source cover 3 via adhesive. When applying a primer to the foam, care must be taken to avoid contaminating the transparent substrate 11 on the inner surface of the hollowed-out logo 121, which would affect the light emission. After the foam is bonded, a protective film must be applied to the foam-covered area to prevent dust and dirt from entering. This film is removed during final assembly to avoid the risk of contamination during transportation and handling. The gap between the inner surface of the entire decorative outer panel 1 and the light source cover 3 should be equidistant.

[0076] The material and shape of the sealing element 4 are not limited to those described in this embodiment and can be flexibly selected according to the actual situation.

[0077] Furthermore, the transparent substrate 11 can also omit the carbon black masterbatch particles and can be made of other light-transmitting materials such as PC material and PMMA material.

[0078] This utility model also proposes a vehicle.

[0079] According to the vehicle of the present utility model embodiment, a light-emitting car logo structure 101 of any of the above embodiments is provided. The light-emitting car logo structure 101 includes a car logo light source 2 and a front bumper upper decorative part 100. The front bumper upper decorative part 100 includes a decorative part outer plate 1. The decorative part outer plate 1 is provided with a transparent substrate 11, a hollow layer 12 and a light-transmitting paint layer 13 stacked in sequence along the irradiation direction of the car logo light source 2. The transparent substrate 11 can appear dark when the car logo light source 2 is not irradiated, so that the hollow car logo 121 appears dark. The transparent substrate 11 can also appear white when the car logo light source 2 is irradiated, so that the hollow car logo 121 appears white. This reflects the different colors of the hollow car logo 121. Its design is ingenious and easy for users to observe. Furthermore, the hollow car logo 121 is engraved on the hollow layer 12, which can provide a variety of hollow car logo 121 patterns and make the production more flexible.
