[0002] With the development of automobile technology, people have higher and higher requirements on the aesthetic appearance of car lights. Simple pattern display can no longer meet users' demand for shape, especially the shapes displayed by car rear position lights are becoming more and more diverse.

[0003] In the prior art, an exterior mirror includes an exterior mirror body and a light-transmitting membrane, wherein the light-transmitting membrane is fixedly connected to a pattern portion of the exterior mirror body by an in-mold insert injection molding process. The mold structure of the in-mold injection molding scheme used is complex, and the membrane cost is relatively high. The membrane is only suitable for relatively flat shapes. If a scheme with a relatively large change in the curvature of the shape is encountered, the membrane cannot be smoothly covered, which has limitations.

[0004] In view of this, it is necessary to design a spray-painted laser-engraved customizable position lamp luminous structure to solve the above problems. Utility Model Content

[0006] To this end, the utility model provides a paint-sprayed laser-engraved customizable position lamp luminous structure, which can meet the modeling requirements of complex curved surfaces while ensuring luminous uniformity.

[0007] According to the first aspect of the utility model, a painted laser-engraved customizable position lamp light-emitting structure is provided, comprising a decorative ring, a light-emitting unit, a circuit board and a bracket, the decorative ring being clamped with the bracket, the light-emitting unit and the circuit board being arranged between the decorative ring and the bracket, the circuit board being connected to the bracket, the light-emitting unit being arranged on the circuit board, the light emitted by the light-emitting unit being suitable for being emitted through a light-transmitting portion on the decorative ring, and a light-transmitting pattern layer being arranged at the light-transmitting portion, the light emitted by the light-emitting unit being suitable for being emitted through the light-transmitting pattern layer to form a light-emitting pattern.

[0008] Preferably, the decorative ring includes a light blocking portion and a light transmitting portion, the light blocking portion is connected to the light transmitting portion to limit the light emitted by the light emitting unit from passing through, the light transmitting portion is located on the emission path of the light emitted by the light emitting unit, and the light emitted by the light emitting unit is suitable for being dispersed by the light transmitting portion to form uniform light emission.

[0009] Further preferably, the light emitting unit is adapted to be arranged directly opposite to the light-transmitting portion, so that the light emitted by the light emitting unit directly irradiates the light-transmitting portion.

[0010] Preferably, the light-emitting unit is not disposed directly opposite the light-transmitting portion, so that the light emitted by the light-emitting unit is laterally diffused to the light-transmitting portion and then emitted.

[0011] More preferably, the light-transmitting pattern layer provided on the light-transmitting portion includes a primer layer, a PU topcoat layer, and a laser engraving layer provided in sequence.

[0012] More preferably, the light-transmitting pattern layer provided on the light-transmitting portion includes a primer layer, a laser engraving layer, and a PU varnish layer provided in sequence.

[0013] Preferably, the light-transmitting portion is an injection molded part made of a scattering material, so that the light passing through the injection molded part is emitted evenly.

At the same time, by functionally dividing the decorative ring, the light emitted by the light-emitting unit can pass through the decorative ring. At the same time, a light-transmitting pattern layer is provided on the light-emitting surface of the decorative ring. After the light passes through the light-transmitting pattern layer and is emitted, a set light-emitting pattern is formed. Moreover, when the light passes through the light-transmitting portion of the decorative ring, it can be scattered by the light-transmitting portion and emitted evenly, thereby improving the uniformity of the finally formed light-emitting pattern, being not limited by the appearance and color of the base material, and effectively reducing costs at the same time.

[0030] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model. In the description of the present utility model, it should be understood that unless otherwise specified, the meaning of "a plurality of" is two or more.

[0031] See Figure 1 , a spray painting and laser engraving customizable position lamp lighting structure in a specific implementation manner of the present utility model, includes a decorative ring 1, a lighting unit 2, a circuit board 3 and a bracket 4. The decorative ring 1 is snap-connected to the bracket 4. Between the decorative ring 1 and the bracket 4, there are provided the lighting unit 2 and the circuit board 3. The circuit board 3 is connected to the bracket 4. The lighting unit 2 is arranged on the circuit board 3, and the lighting unit 2 is soldered to the circuit board 3 by reflow soldering. Then, the circuit board 3 and the bracket 4 are fixed by hot riveting welding. The light emitted by the lighting unit 2 is adapted to be emitted through the light transmitting part 12 on the decorative ring 1, and a light transmitting pattern layer 13 is provided at the light transmitting part 12. Therefore, when the light emitted by the lighting unit 2 passes through the light transmitting pattern layer 13 and is emitted, a light emitting pattern preset by the light transmitting pattern layer can be formed.

[0032] Specifically, the decorative ring 1 includes a light-blocking portion 11 and a light-transmitting portion 12. The light-blocking portion 11 is connected to the light-transmitting portion 12. The light-blocking portion 11 can limit the light emitted by the light-emitting unit 2 from passing through, and the light-transmitting portion 12 is located on the light-emitting path of the light emitted by the light-emitting unit 2. Therefore, the light emitted by the light-emitting unit 2 is suitable for passing through the light-transmitting portion 12 and forming a uniform light after being scattered within the light-transmitting portion 12 and then emitting out. The material used for the light-transmitting portion 12 is injection-molded with a scattering material, and different colors can be filled therein to form different light-emitting effects of different colors.

[0033] See Figure 1 , this light-emitting structure has a side-emitting form. When the side-emitting form is adopted, the light-emitting unit 2 is not arranged directly opposite to the light-transmitting portion 12. At this time, the light emitted by the light-emitting unit 2 laterally diffuses to the light-transmitting portion 12 and then emits out. This method is suitable for a structural form with a curved shape.

[0034] See Figure 2 , this light-emitting structure also has a direct-emitting form. When the direct-emitting form is adopted, the light-emitting unit 2 is arranged directly opposite to the light-transmitting portion 12, and the light emitted by it directly emits out after irradiating on the light-transmitting portion 12. This method is suitable for a structural form with a flat shape.

[0035] See Figures 3 to 4 , the light-transmitting pattern layer 13 provided on the light-transmitting portion 12 includes a primer layer, a PU layer, and a laser-engraving layer arranged in sequence. The light-transmitting pattern layer 13 formed by adopting this setting method has distinct edges and clear patterns. However, since the PU topcoat is relatively soft, problems such as scratches are likely to occur during the packaging and turnover process.

[0036] The light-transmitting pattern layer 13 can also adopt another treatment method, that is, a primer layer and a laser-engraving layer are sequentially provided on the outer surface of the light-transmitting portion 12, and finally a PU varnish layer is covered. The light-transmitting pattern layer 13 formed by adopting this method has high gloss and is visually relatively full, but it will produce an effect of accumulated paint visually. Therefore, adopting this method can achieve a rich and colorful appearance effect.

[0037] Specifically, in order to be able to achieve a better dynamic light-emitting effect, the flowing dynamic effect can also be achieved by adjusting the lighting sequence of the light-emitting unit 2.
