Description

Technical Field

[0001] The present invention relates to the field of automotive parts, and particularly to an automotive light-emitting grille and a manufacturing method thereof. Background Art

[0002] An automotive grille can prevent components in the water tank and engine compartment from being impacted. Since the automotive grille is arranged at the front end of the vehicle, it has a great influence on the overall aesthetic degree of the vehicle. In traditional automotive exterior decorations, both the automotive grille and the front bumper are relatively simple plastic products and do not have the function of personalized display. At the same time, if the automotive grille and the front bumper need to have a light-emitting effect, additional exposed parts such as light-emitting strips and lamps need to be added, which will greatly increase the cost of the whole vehicle. When light-emitting components are arranged inside, when not emitting light, the obvious difference between the light-transmitting area and the light-blocking area can still be observed, and the visual effect is poor. Summary of the Invention

[0003] To solve at least one of the above technical problems, the present invention provides an automotive light-emitting grille and a manufacturing method thereof, and the technical solutions adopted are as follows:

[0033] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] As Figure 1 shown, an embodiment of the present invention provides an automotive lighting grille, including a first grille assembly and a second grille assembly.

[0035] As Figure 2 shown, the first grille assembly includes a first grille panel 101, a first light guide plate 102, and a first light source 103. The first grille panel 101 is used to cover the front end of the vehicle body. It can be understood that the length of the first grille panel 101 corresponds to the width of the front end of the vehicle body.

[0036] The first grille panel 101 includes a first accommodating portion 104, a first bending portion 105, and a second bending portion 106. The first bending portion 105 is connected to the bottom edge of the first accommodating portion 104, and the second bending portion 106 is connected to the bottom edge of the first bending portion 105. Further, the first accommodating portion 104, the first bending portion 105, and the second bending portion 106 are integrally formed to improve the integrity of the first grille panel 101. A relatively independent area is formed between the first accommodating portion 104 and the front end of the vehicle body, and each lighting structure is located in the area. Therefore, the first accommodating portion 104 protrudes from the front end of the vehicle body, the top edge of the first accommodating portion 104 abuts against the front end of the vehicle body, and there is a certain distance between the bottom edge of the first accommodating portion 104 and the front end of the vehicle body.

[0037] To improve the structural strength of the first grille panel 101, the first bending portion 105 forms an angle with the first grille panel 101. The first bending portion 105 extends from the bottom edge of the first accommodating portion 104 towards the vehicle body, that is, an edge is formed at the connection between the first bending portion 105 and the first accommodating portion 104, and the edge can resist a certain degree of external impact. The second bending portion 106 forms an angle with the first bending portion 105, and the second bending portion 106 extends from the bottom edge of the first bending portion 105 towards the direction away from the vehicle body, so as to connect other fixing components and fixedly arrange the first grille panel 101 at the front end of the vehicle body.

[0038] The first light guide plate 102 is disposed on the inner side of the first accommodating portion 104, that is, the first light guide plate 102 is located between the first accommodating portion 104 and the front end of the vehicle body. The first light source 103 is disposed along the bottom edge of the first light guide plate 102. It can be understood that the first light source 103 is also located between the first accommodating portion 104 and the front end of the vehicle body. The first light source 103 can emit light, and the light can be transmitted into the first light guide plate 102 through the first light source 103, so as to improve the brightness of the first light guide plate 102. Specifically, the edge of the first light guide plate 102 close to the first light source 103 is set in a serrated shape, and the back is provided with uniform light guide point features, so that the light diverges more evenly on the first light guide plate 102, and the light guide distance is farther. The base material of the first light guide plate 102 is made of optical grade PMMA material.

[0039] In some examples, since the first grille panel 101 protrudes from the front end of the vehicle body, in order to improve the aesthetic degree, the longitudinal section of the first grille panel 101 is arc-shaped, that is, the first grille panel 101 is in an arc-shaped surface. It can be understood that in order to make the first light guide plate 102 fit the inner side of the first grille panel 101, the shape of the first light guide plate 102 is also correspondingly set to an arc-shaped surface.

[0040] In some examples, the first grille assembly further includes a first bottom plate 107. The first bottom plate 107 is connected to the inner side of the first grille panel 101. A relatively independent first accommodating space is formed between the first bottom plate 107 and the first grille assembly. Both the first light guide plate 102 and the first light source 103 are located in the first accommodating space. Ensure that the first light guide plate 102 can fit the first grille panel 101, and the position of the first light source 103 can be stabilized at the bottom edge of the first light guide plate 102. At the same time, avoid collision between the front end of the vehicle body and the first light source 103 and the first light guide plate 102, and improve the durability of the first light source 103 and the first light guide plate 102.

[0041] In some examples, a first sealing member is provided at the connection between the first bottom plate 107 and the first grille panel 101. The first sealing member further ensures the relative independence of the first accommodating space, can meet the dust and water prevention inside the first accommodating space, avoid short circuit of electronic components due to water, avoid the first light guide plate 102 getting dirty due to dust and affecting the light guide performance, and the first bottom plate 107 is connected to the first grille panel 101 through the first sealing member to improve the connection stability, and avoid damage caused by collision between the first bottom plate 107 and the inner side of the first grille panel 101.

[0042] Such as Figure 3As shown, in some examples, the second grille assembly includes a second grille panel 201, a second light guide plate 202, and a second light source 203. The second grille panel 201 is arranged in parallel with the first grille panel 101 and is located below the first grille panel 101. The second grille panel 201 is connected to the license plate holder and together with the license plate holder covers the front end of the vehicle body. It can be understood that there are two second grille panels 201, and the two second grille panels 201 are respectively located on both sides of the license plate holder, and the length of the license plate holder and the sum of the lengths of the two second grille panels 201 correspond to the width of the front end of the vehicle body.

[0043] The second grille panel 201 includes a second accommodation part 204, a third bending part 205, and a fourth bending part 206. The third bending part 205 is connected to the side edge of the second accommodation part 204, and the fourth bending part 206 is connected to the side edge of the third bending part 205. Further, the second accommodation part 204, the third bending part 205, and the fourth bending part 206 are integrally formed to improve the integrity of the second grille panel 201.

[0044] To improve the structural strength of the second grille panel 201, the third bending part 205 forms an angle with the second grille panel 201, and the third bending part 205 extends away from the vehicle body from the side edge of the second accommodation part 204. The third bending part 205 forms an angle with the second bending part 106, and the third bending part 205 extends from the side edge of the second bending part 106 towards the license plate holder, thereby connecting the license plate holder and fixing the second grille panel 201 at the front end of the vehicle body. At the same time, the license plate holder can protrude from the front end of the vehicle body to make the license plate more prominent.

[0045] The second light guide plate 202 is arranged on the inner side surface of the second accommodation part 204, that is, the second light guide plate 202 is located between the second grille panel 201 and the front end of the vehicle body. The second light source 203 is arranged along the side edge of the second light guide plate 202. It can be understood that the second light source 203 is located between the second grille panel 201 and the front end of the vehicle body. The second light source 203 can emit light, and the light can be transmitted to the inside of the second light guide plate 202 through the second light source 203 to improve the brightness of the second light guide plate 202.

[0046] In some examples, since the second grille panel 201 is attached to the front end of the vehicle body, the longitudinal section of the second grille panel 201 is approximately straight, that is, the second grille panel 201 is approximately in a planar shape. It can be understood that to make the second light guide plate 202 fit the inner side surface of the second grille panel 201, the shape of the second light guide plate 202 is also correspondingly set to a planar shape.

[0047] In some examples, the second grille assembly further includes a second bottom plate 207. The second bottom plate 207 is connected to the inner side surface of the second grille panel 201. A relatively independent second accommodation space is formed between the second bottom plate 207 and the second grille assembly, and the second light guide plate 202 is located within the second accommodation space. This avoids collisions between the front end of the vehicle body and the second light guide plate 202, enhancing the durability of the second light guide plate 202.

[0048] In some examples, to ensure the stable position of the second light source 203 and, at the same time, avoid the second light source 203 colliding with other fixed components and enhance the durability of the second light source 203, the second grille assembly further includes a sealed housing, and the second light source 203 is disposed within the sealed housing. Further, the sealed housing is connected to the inner side surface of the fourth bent portion 206 and, at the same time, the sealed housing is connected to the second bottom plate 207. By fixing the position of the sealed housing, the position of the second light source 203 is fixed. Specifically, to ensure that the light emitted by the second light source 203 can enter the second light guide plate 202, a first hollow portion is provided on the sealed housing, and the second light guide plate 202 is disposed through the first hollow portion. The first hollow portion can further fix the position of the second light guide plate 202. A second hollow portion is also provided on the sealed housing, and the second hollow portion is used for the connection line of the second light source 203 to pass through to ensure the power supply of the second light source 203. The edge of the second light guide plate 202 close to the second light source 203 is designed in a serrated shape, and a uniform light guide point feature is designed on the back surface of the second light guide plate 202, making the light diverge more uniformly on the second light guide plate 202 and having a longer light guide distance. The base material of the second light guide plate 202 is made of optical grade PMMA material.

[0049] In some examples, the sealed housing includes a first sealing cover 301 and a second sealing cover 302. The first sealing cover 301 is connected to the second sealing cover 302, facilitating the placement of the second light source 203 within the sealed housing. When the second light source 203 needs to be repaired or replaced, the first sealing cover 301 is separated from the second sealing cover 302. Further, the first sealing cover 301 is close to the second light guide plate 202. Therefore, the first hollow portion is provided on the first sealing cover 301 to facilitate the second light guide plate 202 receiving the light from the second light source 203. The second sealing cover 302 is away from the second light guide plate 202, and the second hollow portion is provided on the second sealing cover 302. The first sealing cover 301 is connected to the second bottom plate 207, and the second sealing cover 302 extends to the position of the fourth bent portion 206 and is connected to the fourth bent portion 206.

[0050] In some examples, a second sealing member is provided at the connection between the second bottom plate 207 and the second grille panel 201. The second sealing member ensures the relative independence of the second accommodation space, can meet the dust and water protection inside the second accommodation space, prevent the electronic components from short - circuiting due to water, prevent the light guide plate from getting dirty due to dust and affecting the light - guiding performance. At the same time, it improves the connection stability between the second bottom plate 207 and the second grille panel 201, and avoids damage caused by collision between the inner sides of the second bottom plate 207 and the second grille panel 201. At the same time, a second sealing member is also provided at the connection between the second sealing cover 302 and the fourth bending portion 206, further isolating the second accommodation space and preventing the external environment from interfering with the components inside the second accommodation space.

[0051] In some examples, after the circuit of the second light source 203 passes through the second hollow portion, glue is applied to the second hollow portion to fix the circuit and, at the same time, play a sealing role. Exhaust holes are provided on the second bottom plate 207 and the second sealing cover 302, and a breathable film or a breathable cap is provided at the position of the exhaust holes.

[0052] A first spray - coated layer is provided on the inner side of the first grille panel 101. The first spray - coated layer can block light, and when light propagates to the first spray - coated layer, it will not continue to pass through. Further, a plurality of light - transmitting areas 303 are provided on the first spray - coated layer. The light - transmitting areas 303 are used to allow light to pass through. The shape and position of the light - transmitting areas 303 are set according to the user's needs, so that when light passes through the light - transmitting areas 303, different patterns can be personalized displayed, improving the aesthetic degree of the front end of the vehicle body. A first spray - coated layer is also provided on the inner side of the second grille panel 201, and light - transmitting areas 303 are provided on the first spray - coated layer.

[0053] In some examples, a second spray - coated layer is provided on the outer sides of the first grille panel 101 and the second grille panel 201. First, a light - transmitting body color paint is sprayed to form a light - transmitting body color paint layer, and then a transparent clear paint is sprayed on the basis of the light - transmitting body color paint to form a transparent clear paint layer. The light of the light - transmitting areas 303 can pass through the light - transmitting body paint to ensure the propagation of light, and the clear paint makes the vehicle body shiny and resists stone impacts.

[0054] As Figure 4 shown, in some examples, the first light source 103 and the second light source 203 adopt strip - shaped LED lamp groups, and a scheme of controlling the LEDs in series with matrix chips is adopted. Instructions are sent by the MCU to control the lighting and extinguishing of the LEDs, thereby realizing a breathing or flowing display effect and improving the aesthetic degree of the lighting.

[0055] An embodiment of the present invention provides a method for manufacturing an automotive light - emitting grille.

[0056] The base materials of the first grille panel 101 and the second grille panel 201 are both made of high-transparency and high-haze PP materials and are formed on the basis of the PP materials. The inner sides of the first grille panel 101 and the second grille panel 201 are sprayed with PP primer and light-shielding black paint. Specifically, the PP material is added with a milky white color masterbatch according to a ratio of about 1:0.05 to form a light-transmitting PP material with a diffusing effect, and the light transmittance is controlled between 30% and 50%. Alternatively, PC material can be selected to replace the light-transmitting PP material.

[0057] Place the first grille panel 101 and the second grille panel 201 under hot air at the first temperature for drying for the first duration. Specifically, the first temperature is about 75 °C, and the first duration is about 40 minutes.

[0058] After the drying process is completed, a light-transmitting area or pattern is laser engraved on the first spray coating. The laser engraving uses numerical control technology with laser as the processing medium. The first spray coating undergoes physical denaturation of instantaneous melting and vaporization under the irradiation of laser engraving. The pattern laser engraved is not easily worn and has strong durability.

[0059] On the outer sides of the first grille panel 101 and the second grille panel 201, first spray PP primer, then spray light-transmitting body color paint and clear paint, so that the outer sides of the first grille panel 101 and the second grille panel 201 present the same color as the body. When not irradiated, it is difficult to observe the light-transmitting area 303 on the surfaces of the first grille panel 101 and the second grille panel 201, improving the integrity of the vehicle body and the aesthetic degree. Specifically, the body color paint forms a variety of light-transmitting body colors by adding light-transmitting agents in different proportions according to different colors. Among them, the light-transmitting black body color paint has the lowest transmittance, which can reach 5% to 8% of the light transmittance, and the transmittance of other colors is relatively increased, with the maximum being white, and the maximum transmittance can reach 30%.

[0060] Similar to the treatment of the inner sides of the first grille panel 101 and the second grille panel 201, place the first grille panel 101 and the second grille panel 201 under hot air at the second temperature for drying for the second duration. Specifically, the second temperature is about 75 °C, and the second duration is about 40 minutes.

[0061] After the power is turned on, different colored bright dynamic pattern effects can be seen from the first grille panel 101 and the second grille panel 201 with body color. After the power is turned off, the bright pattern disappears, and only the body color on the outer sides of the first grille panel 101 and the second grille panel 201 can be seen, realizing the complete hiding of the bright pattern.

[0062] During the assembly process of the second grille assembly, first, the first light source 103 is installed by ultrasonic welding with the first sealing cover 301, the second sealing cover 302, and the second light guide plate 202, and then it is hermetically assembled and fixed with the second grille panel 201 and the second bottom plate 207 after painting and laser engraving patterns.
