Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a light-emitting structure and an automobile. Background Art

[0002] With the large-scale popularization of new energy vehicles, the front and rear logos of automobiles have developed from traditional ordinary logos to light-emitting logos. The light-emitting logos on the market have various forms and thousands of effects, such as simple milky white area light-emitting, body color light-emitting, red transparent light-emitting, and metal electroplating color light-emitting. In the related art, metal light-emitting logos are used on many automobiles. However, most of them are planar light-emitting logos, and the logo area is not highlighted, and the overall wall thickness is uniform, so there is an obvious boundary between the light-emitting area and the non-light-emitting area.

[0003] Compared with the planar light-emitting logo, the three-dimensional and prominent light-emitting vehicle logo has a stronger visual impact. The three-dimensional design is usually more eye-catching and can produce a stronger impact and recognition visually. At the same time, the three-dimensional and prominent light-emitting vehicle logo can also improve the recognition of the logo at night. The light-emitting characteristics make the logo more conspicuous at night or in an environment with insufficient light, improving the visibility of the vehicle. Therefore, the three-dimensional and prominent light-emitting logo is more popular than the planar light-emitting logo. Summary of the Invention

For this purpose, the utility model provides a light-emitting structure, which can make there be no obvious boundary between the light-emitting area and the non-light-emitting area of the light-emitting structure and improve the aesthetic degree.

Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0034] With the wide promotion of new energy vehicles, the design of vehicle logos (LOGOs) also tends to adopt light-emitting elements to distinguish from traditional static LOGOs. At present, the light-emitting LOGO technologies on the market are diverse, including single milky white light emission, light-emitting effects of the same color as the vehicle body, red transparent light emission, and electroplated color light emission with a metallic texture, each with its own characteristics.

[0035] Although the light-emitting LOGOs with a metallic texture have been applied in many automobile brands, most designs still stay in the stage of planar light emission, lacking a three-dimensional sense, making the boundary between the light-emitting area and the non-light-emitting area clear, which to a certain extent limits its visual attraction.

[0036] Compared with the planar light-emitting structure, the three-dimensional designed light-emitting vehicle logo can attract people's attention more due to its prominent visual effect, enhancing the brand recognition. In a night or a dim environment, the light-emitting characteristics of the three-dimensional light-emitting structure also significantly improve the visibility and safety of the vehicle. At the same time, compared with the planar light-emitting structure, since the light-transmitting area protrudes from the non-light-transmitting area in the three-dimensional light-emitting structure, there is no obvious boundary between the light-transmitting area and the non-light-transmitting area, improving the visibility and aesthetics at night.

[0037] Therefore, based on the problems existing in the related technologies, the present application designs a three-dimensional metallic light-emitting structure, which, compared with the planar light-emitting structure of the existing technology (for the convenience of description, hereinafter also referred to as the light-emitting LOGO), can make there be no obvious boundary between the light-emitting area and the non-light-emitting area of the light-emitting structure, improving the aesthetic degree.

[0038] Reference Figures 1 to 5 , mainly referring to Figure 1 、 Figure 2 , according to the light-emitting structure of the first aspect of the present utility model, it includes a substrate 100, a light-transmitting member 200, a diffusing member 300, a circuit board 400 and a housing 500. The light-transmitting member 200 is mounted on the substrate 100. The light-transmitting member 200 includes a light-transmitting area 210 and a non-light-transmitting area 220210. The light-transmitting area 210 protrudes from the non-light-transmitting area 220210 along the thickness direction of the light-transmitting member 200. The diffusing member 300 is disposed between the light-transmitting member 200 and the substrate 100, and the diffusing member 300 has a first surface 301, and the first surface 301 is closely attached to the side of the light-transmitting member 200 facing the substrate 100. The circuit board 400 is disposed between the diffusing member 300 and the substrate 100. The housing 500 is provided with an extending hole 501. The light-transmitting area 210 extends out of the housing 500 through the extending hole 501, and the non-light-transmitting area 220210 is covered by the housing 500.

[0039] In this application, the light-emitting structure mainly includes a substrate 100, a light-transmitting member 200, a diffusing member 300, a circuit board 400 and a housing 500. The housing 500 is provided with an extending hole 501. The light-transmitting member 200 includes a light-transmitting area 210 and a non-light-transmitting area 220210. The thickness of the light-transmitting area 210 is set to be larger than that of the non-light-transmitting area 220210, so that when the light-transmitting member 200 and the housing 500 are mutually installed, the light-transmitting area 210 of the light-transmitting member extends out from the extending hole 501 to form the light-emitting part of the light-emitting LOGO, that is, the part that forms the LOGO pattern exposed outside. The non-light-transmitting area 220210 is the part covered by the housing 500. By setting the thickness of the light-transmitting area 210 to be greater than the thickness of the non-light-transmitting area 220210, there is no obvious boundary between the light-transmitting area 210 and the non-light-transmitting area 220210, improving the visibility and aesthetics at night.

[0040] In some embodiments, a second surface 221 is formed on one side of the light-blocking region 220210 facing the housing 500. The second surface 221 is provided with surface texture, and the texture depth of the surface texture is set within the range of 0.032 mm to 0.052 mm. Specifically, in the related art, light reflection occurs between the three-dimensional metal light-emitting structure housing 500 and the light-transmitting member 200. Since this reflection phenomenon also occurs in the light-blocking region 220210 (i.e., the part of the light-transmitting member 200 blocked by the housing 500), the light emitted through the light-transmitting member 200 irradiates the inner surface of the housing 500 (i.e., the surface facing the light-transmitting member 200) and is reflected on the inner surface of the housing 500, irradiating the surface texture of the inner surface of the housing 500 onto the metal layer at the bottom of the light-transmitting member 200. At this time, the metal layer and the light-transmitting member 200 form a mirror effect, reflecting the detailed texture of the light-blocking region 220210 from the light-transmitting region 210, resulting in reflected patterns at the edges of the light-emitting LOGO, and further resulting in a pattern of boundaries in the light-transmitting region 210 (i.e., the light-emitting region) of the light-emitting LOGO, affecting the light-emitting effect. In the present application, by changing the surface texture at the light-blocking region 220210, the light propagation path is changed, and the mirror phenomenon caused by reflection in the light-blocking region 220210 is avoided, forming a light-emitting structure in which only the light-transmitting region 210 emits light, without forming other patterns or textures in the light-transmitting region 210, and further forming a light-emitting structure in which the light-transmitting region 210 emits light fully, with uniform brightness and no texture reflection.

[0041] In addition, in the present application, for the setting of the texture depth of the surface texture, it should neither be too shallow nor too deep. If the texture depth is too shallow, the effect of changing the light propagation path cannot be achieved. The light emitted through the light-transmitting member 200 irradiates the inner surface of the housing 500 and is reflected on the inner surface of the housing 500, still irradiating the surface texture of the inner surface of the housing 500 onto the metal layer at the bottom of the light-transmitting member 200, and further resulting in a pattern of boundaries in the light-transmitting region 210 (i.e., the light-emitting region) of the light-emitting LOGO, affecting the light-emitting effect. If the texture depth is too deep, light refraction will occur at the texture, interfering with the overall brightness of the light-emitting LOGO and resulting in uneven brightness of the light-emitting LOGO, also affecting the light-emitting effect. Therefore, in the present application, the texture depth of the surface texture is preferably set within the range of 0.032 mm to 0.052 mm, so that the texture depth of the surface texture is neither too deep nor too shallow, changing the light propagation path, and avoiding the mirror phenomenon caused by reflection in the light-blocking region 220210, forming a light-emitting structure in which only the light-transmitting region 210 emits light, without forming other patterns or textures in the light-transmitting region 210, and further forming a light-emitting structure in which the light-transmitting region 210 emits light fully, with uniform brightness and no texture reflection.

[0042] Refer to Figure 3, in some embodiments, the substrate 100 is provided with a first positioning portion 110, and the diffuser 300 is provided with a second positioning portion 310. The diffuser 300 is fixedly installed on the substrate 100 through the first positioning portion 110 and the second positioning portion 310. Specifically, in order to stably install the diffuser 300 on the substrate 100, the first positioning portion 110 can be provided on the substrate 100, and the second positioning portion 310 can be provided on the diffuser 300. In this application, as an example, the first positioning portion 110 can be a positioning post, and the second positioning portion 310 can be an insertion hole. The positioning post is inserted into the insertion hole to install and fix the diffuser 300 and the substrate 100 to each other. It can be understood that the first positioning portion 110 can also be set as an insertion hole, and the second positioning portion 310 can be set as a positioning post, and the positioning post is inserted into the insertion hole to install and fix the diffuser 300 and the substrate 100 to each other. In addition, a through hole or a threaded hole is provided in the positioning post. After the positioning post is inserted into the insertion hole, a fixing pin or a bolt is inserted into the through hole or the threaded hole provided in the positioning post and tightened to further improve the connection strength between the diffuser 300 and the substrate 100.

[0043] Further, self-tapping screws can also be provided between the diffuser 300 and the substrate 100. By locking the self-tapping screws, the connection stability between the diffuser 300 and the substrate 100 is further increased.

[0044] In some embodiments, the circuit board 400 is fixedly arranged between the diffuser 300 and the substrate 100 through the first positioning portion 110 and the second positioning portion 310, and the second positioning portion 310 abuts against the circuit board 400. As described above, in this application, the first positioning portion 110 is preferably set as a positioning post, and the second positioning portion 310 is preferably set as an insertion hole. The end face of the second positioning portion 310 close to the first positioning portion 110 abuts against the circuit board 400 and presses the circuit board 400 tightly. At the same time, in order to cooperate with the end face of the second positioning portion 310 to further limit the position of the circuit board 400, the first positioning portion 110 is also provided with a step portion. The circuit board 400 is placed on the step portion, and the two sides of the circuit board 400 are respectively pressed and fixed by the end face of the first positioning portion 110 and the step portion, so that the circuit board 400 is pressed and compacted without a gap by the end face of the first positioning portion 110 and the step portion, and the circuit board 400 is stably fixed, avoiding situations such as loosening and shaking of the circuit board 400, thereby increasing the overall stability of the light-emitting structure.

[0045] In addition, referring to Figure 4, In order to further define the position of the circuit board 400, the substrate 100 is further provided with a limiting portion 140 which extends from the inner surface of the substrate 100 towards the diffusing member 300 to fix the circuit board 400 at the edge thereof. In this application, the limiting portion 140 adopts a structure with a protrusion at one end to clamp the circuit board 400. Of course, as long as it can limit and fix the circuit board 400, the structure of the limiting portion 140 is not limited thereto, and a slot type or other fixing methods can also be adopted.

[0046] In some embodiments, the light-transmitting member 200 is made of polymethyl methacrylate and is formed by the method of twist gate feeding. The impact force of the molten material during injection is reduced by a curved channel, and extra space is reserved at the end of the gate for cold material filling to ensure uniform temperature of the molten material of the molded product. By optimizing the gate design, the injection is made uniform and there is no shrinkage on the surface of the product, and the weld line is at the edge without affecting the appearance. Specifically, by taking measures at the curved channel to reduce the impact force of the molten material during injection, a certain amount of extra space can be reserved at the end of the gate for filling cold material. This can effectively ensure uniform temperature distribution of the molten material of the molded product and avoid product quality problems caused by uneven temperature. In addition, by optimizing the gate design, the uniformity of the injection process can be achieved, thus ensuring that there is no shrinkage on the surface of the product. At the same time, by reasonably arranging the position of the weld line so that it is located in the edge area of the product, the adverse impact of the weld line on the appearance of the product can be effectively avoided.

[0047] In some embodiments, the deformation range of the light-transmitting member 200 in the thickness direction is from 0.693 mm to -0.335 mm, the deformation range of the light-transmitting member 200 in the first direction perpendicular to the thickness direction is from 0.499 mm to -0.578 mm, and the deformation range of the light-transmitting member 200 in the second direction perpendicular to both the thickness direction and the first direction is from 0.599 mm to -0.588 mm. Specifically, setting the deformation range of the light-transmitting member 200 in the thickness direction can optimize the structure of the product to a certain extent to adapt to the stress and deformation during the molding process, enhance the durability and reliability. At the same time, it can enable the light-transmitting member 200 to have a longer service life and higher reliability after high-pressure molding.

[0048] In this embodiment, the first direction is the left-right direction in the figure, the second direction is the up-down direction in the figure, and the thickness direction of the light-transmitting member 200 is the front-back direction in the figure.

[0049] In some embodiments, along the thickness direction of the light-transmitting member 200, the thickness difference between the thickness of the light-transmitting region 210 and the non-light-transmitting region 220 (should be 220 here instead of 220210 in the original text) is 6 to 8 mm. In this embodiment, since the light-transmitting member 200 is the main part for forming the LOGO to emit light (the light-transmitting region 210), it is necessary to distinguish between the light-transmitting region 210 and the non-light-transmitting region 220 of the light-transmitting member 200. Specifically, by setting the thicknesses of the light-transmitting region 210 and the non-light-transmitting region 220 in the thickness direction of the light-transmitting member 200 to be different, that is, setting the thickness of the light-transmitting region 210 that needs to protrude from the housing 500 to be greater than the non-light-transmitting region 220 that needs to be covered by the housing 500, it is possible to make only the light-transmitting region 210 emit light to form a three-dimensional light-emitting LOGO. Thus, the three-dimensional light-emitting LOGO of the present application is different from the planar LOGO of the prior art and does not require an additional LOGO boundary. Therefore, there is no obvious boundary between the light-emitting LOGO of the present application and the surrounding area, and the light-emitting effect can be better presented. In the present application, the thickness difference between the thickness of the light-transmitting region 210 and the non-light-transmitting region 220 is preferably 7 mm.

[0050] Referring to Figure 5 , in some embodiments, the diffuser 300 is provided with a fixing portion 320, and the substrate 100 is provided with a mounting portion 120. The fixing portion 320 cooperates with the mounting portion 120, and the diffuser 300 and the substrate 100 are fixedly connected through the fixing portion 320 and the mounting portion 120. Specifically, in order to ensure the internal structural stability of the light-emitting structure, the light-transmitting member 200 and the substrate 100 are mutually lapped and buckled through the lapping portions at their respective edges. The diffuser 300 is disposed between the light-transmitting member 200 and the substrate 100. In addition to being mutually positioned and fixed through the first positioning portion 110 and the second positioning portion 310 located at approximately the middle position of the light-emitting structure, the diffuser 300 and the substrate 100 are fixedly installed by providing a mounting portion 120 on the substrate 100 and a fixing portion 320 on the diffuser 300, and installing the fixing portion 320 in the mounting portion 120. Among them, the mounting portion 120 is disposed at a position on the substrate 100 closer to the edge of the substrate 100 relative to the first positioning portion 110, and the fixing portion 320 is disposed at a position on the diffuser 300 closer to the edge of the diffuser 300 relative to the second positioning portion 310. Thus, the diffuser 300 and the substrate 100 are fixedly installed through the first positioning portion 110 and the second positioning portion 310 located at approximately the middle position, and the diffuser 300 and the substrate 100 are fixedly installed through the mounting portion 120 and the fixing portion 320 located at approximately the edge position, further improving the installation strength of the diffuser 300 and the substrate 100. At the same time, it is also possible to avoid adding other parts for fixing and simplify the internal structure of the device.

[0051] In some embodiments, the substrate 100 is further provided with auxiliary ribs 130. There is a gap between the auxiliary ribs 130 and the mounting portion 120. The fixing portion 320 passes through the gap and is snap-fitted to the mounting portion 120. The auxiliary ribs 130 and the mounting portion 120 are arranged at intervals. When the fixing portion 320 is mounted on the mounting portion 120, the fixing portion 320 and the mounting portion 120 are abutted and fixed on one side of the fixing portion 320, and the auxiliary ribs 130 press the fixing portion 320 on the other side of the fixing portion 320 to prevent the fixing portion 320 from loosening, resulting in unstable direct connection between the diffusing member 300 and the substrate 100. In addition, the thickness of the auxiliary ribs 130 can be set to 1.3 - 1.6 mm. On the one hand, it can press the fixing portion 320 to prevent loosening, and on the other hand, it can simplify the internal structure of the light-emitting structure and miniaturize it.

[0052] In addition, the diffusing member 300 can also be provided with reinforcing ribs 330. The reinforcing ribs 330 are connected to the fixing portion 320 to prevent the fixing portion 320 from breaking when the fixing portion 320 is mounted between the mounting portion 120 and the auxiliary ribs 130. Specifically, the length relationship between the reinforcing ribs 330 and the fixing portion 320 in the thickness direction of the light-transmitting member 200, that is, the ratio between the reinforcing ribs 330 and the fixing portion 320 is about 0.4 to 0.6.

[0053] The vehicle according to the first aspect of the present invention includes the light-emitting structure according to any one of the above. By using the light-emitting structure of the present application in a vehicle, the LOGO of the vehicle can have a good visual effect at night. By setting the thickness of the light-transmitting area 210 to be greater than the thickness of the non-light-transmitting area 220210, there is no obvious boundary between the light-transmitting area 210 and the non-light-transmitting area 220210, improving the visibility and aesthetics at night.
