Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a light-up bumper. Background Technology

[0002] In recent years, with the rapid development of the new energy vehicle industry, automotive exterior design has shown a trend towards functional integration and visual symbolism. Among them, exterior lighting systems, especially illuminated bumpers, have become the core carriers of brand design language.

[0003] Current illuminated bumper designs require independent installation of light distribution lenses, light-diffusing plates, and matching optical structural components. They also rely on mechanical fasteners such as metal brackets and elastic clips to achieve multi-level assembly with the bumper body, resulting in complex structures and high production costs. Utility Model Content

[0004] The purpose of this utility model is to overcome at least one of the defects of the prior art and provide a light-emitting bumper. This utility model realizes the light emission of the bumper by directly connecting the light-emitting lamp group to the bumper body, reducing the input of parts, such as light distribution lens, light doubling plate, etc., simplifying the product structure design and reducing the cost of parts.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0007] The bumper body includes a base material and a paint layer disposed on the display side of the base material, wherein the paint layer has multiple light-emitting areas;

[0008] The light-emitting light assembly located on the back of the bumper body includes a base and a circuit board mounted on the base, the base being connected to the bumper body.

[0009] Furthermore, the paint layer includes a colored layer and a protective layer stacked sequentially from the inside out, and the colored layer is laser-engraved or etched to form a light-emitting area.

[0010] Furthermore, the colored layer includes a primer layer, a colored paint layer, and a first clear coat layer stacked sequentially from the inside out.

[0011] Furthermore, the thickness of the primer layer is greater than 8 μm; the thickness of the color paint layer is 15 μm to 25 μm; and the thickness of the first clear coat layer is 10 μm to 15 μm.

[0012] Furthermore, the protective layer comprises a transparent primer layer and a second clear coat layer stacked sequentially from the inside out.

[0013] Furthermore, the thickness of the transparent primer layer is 5μm to 10μm; the thickness of the second clear coat layer is 10μm to 15μm.

[0014] Furthermore, the substrate is an injection-molded part made of polypropylene.

[0015] Furthermore, the circuit board and the base are formed as a whole by bolts, adhesive, or welding; the base and the bumper body are formed as a whole by bolts, adhesive, or welding.

[0016] Furthermore, when adhesive bonding is used, the thickness of the adhesive layer formed by the adhesive bonding is 1.0mm to 2.0mm, and the width is 10mm to 20mm.

[0017] Furthermore, when welding is used, the welding is either vibration friction welding or hot plate welding.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] (1) This utility model realizes the illumination of the bumper by directly connecting the light-emitting lamp group to the bumper body, reducing the investment in parts such as light distribution lens and light distribution plate, simplifying the product structure design and reducing the cost of parts.

[0020] (2) This utility model forms a light-emitting area by peeling off a portion of the paint layer, ensuring that light is emitted only from the light-emitting area and ensuring the uniformity of light emission. When the light-emitting lamp group is lit, the light passes through the light-emitting area and presents a color different from the color of the colored layer, thus avoiding the occurrence of color difference.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are implemented based on the technical solution of the present invention, providing detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0027] Example

[0028] This embodiment provides a light-up bumper; see the specific structure below. Figure 1-4 It includes the bumper body and the light-emitting lamp assembly located on the back of the bumper body;

[0029] The bumper body includes a base material 1 and a paint layer disposed on the display side of the base material 1, wherein the paint layer has multiple light-emitting areas 2;

[0030] The light-emitting light assembly includes a base 8 and a circuit board 9 disposed on the base 8, and the base 8 is connected to the bumper body.

[0031] Please see again. Figure 2 In this embodiment, the paint layer includes a colored layer and a protective layer stacked sequentially from the inside out. The colored layer is peeled off by laser engraving or etching to form the light-emitting area 2. The colored layer includes a primer layer 7, a colored paint layer 6, and a first clear varnish layer 5 stacked sequentially from the inside out. The protective layer includes a transparent primer layer 4 and a second clear varnish layer 3 stacked sequentially from the inside out.

[0032] In this embodiment, the primer layer 7 is a gray primer layer with a thickness greater than 8μm, which has a good light-shielding effect and can prevent the light emitted by the light-emitting lamp assembly from passing through the primer layer 7; the color paint layer 6 is a paint layer with a thickness of 15μm to 25μm and a color consistent with the body color, thereby avoiding color difference and improving the overall aesthetics of the vehicle; the first clear coat layer 5 has a thickness of 10μm to 15μm and can protect the color paint layer 6; the transparent primer layer 4 has a thickness of 5μm to 10μm and can provide better adhesion between clear coats; the second clear coat layer 3 has a thickness of 10μm to 15μm.

[0033] In this embodiment, the substrate 1 is an injection molded part made of polypropylene. Preferably, the polypropylene is milky white and has good light transmission and uniform light distribution, which can ensure that the light emitted by the light-emitting lamp group is emitted through the light-emitting area 2.

[0034] In this embodiment, the circuit board 9 and the base 8 are formed as a whole by bolts, adhesive, or welding, thus forming the assembly of the lamp group of the invention. Figure 3 The circuit board 9 has multiple LED beads integrated on the side facing the substrate 1.

[0035] In this embodiment, the base 8 and the bumper body are formed as a whole by bolts, adhesive, or welding. The connection method must meet the strength requirements between the parts, as well as the requirements for water tightness and air tightness. Specifically, when using adhesive bonding, the adhesive layer 10 formed is 1.0mm to 2.0mm thick and 10mm to 20mm wide. Figure 4 This parameter range can simultaneously ensure mechanical strength and sealing performance. When welding is used, vibration friction welding or hot plate welding is preferred. These two hot fusion methods can achieve the design strength requirements and form a continuous and dense sealing interface by melting and bonding the materials themselves.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
