Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a two-color decorative plate and a vehicle. Background Art

[0002] Because two-color injection molding technology can combine two or more colors in a single product, it has been widely used in the design of vehicle trim panels, particularly taillight trim panels. At night or in low-light conditions, two-color injection molded taillight trim panels can more clearly display the vehicle's outline and position, improving driving safety. However, existing technologies often suffer from problems such as uneven edges, whitening, or ripples at the joints between two color injection molded parts. These issues not only affect the product's aesthetics but also its overall quality and durability. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a two-color decorative panel that effectively avoids problems such as deformation, whitening, or water ripples, thereby improving overall quality and durability.

[0006] According to an embodiment of the present invention, the two-color decorative panel is an injection-molded part. The first color part has a groove, and the second color part is positioned within the groove. The first end of the second color part extends beyond the surface of the first color part having the groove, so that the second color part is injected before the first color part.

[0013] In some embodiments of the present invention, the thickness of any two points on the bottom wall of the groove is the same and is 2 mm.

[0014] In some embodiments of the present invention, the thickness of the first color part in the area outside the groove is constant and is 2.5 mm to 3 mm.

[0015] A vehicle according to an embodiment of the present invention includes the above-mentioned two-color decorative panel.

[0016] According to an embodiment of the present invention, a vehicle is provided with a two-color decorative panel. The two-color decorative panel is an injection-molded part. A first color part has a groove, and a second color part is positioned within the groove. The first end of the second color part extends beyond the surface of the first color part having the groove, so that the second color part is injected before the first color part. This prevents the melt of the first color part from seeping into the second color part during the subsequent injection molding of the first color part, thereby preventing color bleeding. Furthermore, the thickness of the first end is a, and the thickness of the bottom wall of the groove opposite the first end is b, where a:b = 0.75:1-1.5:1.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] The following describes a two-color decorative panel 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, according to the two-color decorative panel 100 of an embodiment of the present invention, the two-color decorative panel 100 is an injection-molded part and includes a first color part 1 and a second color part 2. The first color part 1 has a groove 11, and the second color part 2 is located in the groove 11. The first end 211 of the second color part 2 extends beyond the surface of the first color part 1 having the groove 11. The second color part 2 is injected before the first color part 1. The thickness of the first end 211 is a, and the thickness of the bottom wall of the groove 11 opposite to the first end 211 is b, wherein a:b=0.75:1-1.5:1.

[0030] It can be understood that in the production process of the two-color decorative panel 100, the second color part 2 is first formed by injection molding through a mold, and then the first end 211 of the second color part 2 extends beyond the part of the first color part 1 having the groove 11 to cooperate with the sealing structure of the mold, so that the injection molding machine applies a certain pressure to the contact area between the second color part 2 and the sealing structure to fill the gap between the two and form a close contact surface, thereby preventing the melt of the first color part 1 from penetrating into the second color part 2 during the subsequent injection molding of the first color part 1, thereby preventing color bleeding.

[0031] The second color piece 2 is injected before the first color piece 1. The thickness of the first end 211 is a, and the thickness of the bottom wall of the groove 11 opposite the first end 211 is b, where a:b = 0.75:1-1.5:1. Thus, by limiting the lower limit of the thickness of the first end 211, it is avoided that the thickness of the first end 211 is too small, resulting in insufficient strength of the first end 211, which could cause the impact force generated during the injection molding of the first color piece 1 to cause deformation, whitening, or water ripples on the first end 211. At the same time, by limiting the upper limit of the thickness of the first end 211, it is avoided that the thickness of the first end 211 is too large, resulting in the melt requiring a longer flow path and higher pressure to completely fill the mold cavity, resulting in a longer injection cycle, reduced production efficiency, and increased costs.

[0032] Therefore, by limiting the ratio between the thickness of the first end 211 and the thickness of the bottom wall of the groove 11 opposite the first end 211, the present application effectively improves the structural strength of the first end 211. While ensuring that the first end 211 has sufficient strength to withstand the injection molding pressure of the first color component 1, and avoiding deformation, whitening, or water ripples after the first end 211 is supported and molded, the injection molding cycle and cost of the second color component 2 are reduced, thereby improving the overall quality and durability of the two-color decorative panel 100 and reducing the cost of the two-color decorative panel 100. Specifically, the thickness of the first end 211 is a, and the thickness of the bottom wall of the groove 11 opposite the first end 211 is b, and a:b = 0.75:1-1.5:1. It is understandable that the thickness of the first end 211:the thickness of the bottom wall of the groove 11 opposite to the first end 211 can be 0.75:1, 0.8:1, 0.9:1, 1:1, 1.1:1, 1.2:1, 1.3:1, 1.4:1 or 1.5:1.

[0033] Further, if Figure 1 As shown, there are two second-color pieces 2, with grooves 11 located on two corresponding second-color pieces 2. The two second-color pieces 2 are symmetrically arranged, and the first ends 211 of the two second-color pieces 2 are the ends closest to each other. This arrangement prevents deformation, whitening, or ripples on the first ends 211 of the two second-color pieces 2, further improving the overall quality and durability of the two-color decorative panel 100.

[0034] Optionally, the two-color decorative panel 100 of the present application can be used as a taillight decorative panel of a vehicle.

[0035] According to an embodiment of the present invention, the two-color decorative panel 100 is an injection-molded part. A first color component 1 has a groove 11, and a second color component 2 is positioned within the groove 11. Because the first end 211 of the second color component 2 extends beyond the surface of the first color component 1 having the groove 11, the second color component 2 is injected before the first color component 1. This prevents the melt of the first color component 1 from seeping into the second color component 2 during the subsequent injection molding of the first color component 1, thereby preventing color bleeding. Furthermore, the thickness of the first end 211 is a, and the thickness of the bottom wall of the groove 11 opposite the first end 211 is b, where a:b = 0.75:1-1.5:1. This ensures sufficient injection pressure from the first end 211 on the first color component 1, preventing deformation, whitening, or water ripples after the first end 211 is supported and molded. This reduces the injection molding cycle and cost of the second color component 2, thereby improving the overall quality and durability of the two-color decorative panel 100 and reducing the cost of the two-color decorative panel 100.

[0036] In some embodiments of the present invention, Figure 2As shown, 1.5mm≤a≤2.5mm. Thus, by limiting the thickness of the first end 211, the structural strength of the first end 211 is improved, ensuring that the first end 211 has sufficient strength to withstand the injection molding pressure of the first color component 1, thereby avoiding deformation, whitening, or water ripples after the first end 211 is supported and molded. At the same time, the injection molding cycle and cost of the second color component 2 are reduced. At the same time, the thickness of the bottom wall of the groove 11 opposite the first end 211 can be determined based on the thickness of the first end 211 and in combination with a:b = 0.75:1-1.5:1. Specifically, the thickness of the first end 211 can be 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, or 2.5mm.

[0037] In some embodiments of the present invention, Figure 2 As shown, the first end 211 protrudes beyond the first color element 1 by a dimension c, where 0.5 mm ≤ c ≤ 1.5 mm. It will be appreciated that a portion of the first end 211 is located within the groove 11, while the remaining portion protrudes beyond the first color element 1. Thus, by limiting the extent to which the first end 211 protrudes beyond the first color element 1, the structural strength of the first end 211 is enhanced while preventing localized stress caused by the extent to which the first end 211 protrudes beyond the first color element 1, thereby improving overall reliability. Specifically, the extent to which the first end 211 protrudes beyond the first color element 1 is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm.

[0038] In some embodiments of the present invention, Figure 2 As shown, the angle between the surface of the first end 211 of the second color piece 2 facing away from the bottom wall of the groove 11 and the side wall of the groove 11 close to the first end 211 is d, wherein 80°≤d≤135°.

[0039] It can be understood that by limiting the lower limit angle between the surface of the first end 211 of the second color part 2 away from the bottom wall of the groove 11 and the side wall of the groove 11 close to the first end 211, it is avoided that the angle between the surface of the first end 211 of the second color part 2 away from the bottom wall of the groove 11 and the side wall of the groove 11 close to the first end 211 is too small. While ensuring that the injection pressure of the first end 211 on the first color part 1 is strong enough, the extrusion of the first end 211 is reduced so that the first end 211 has sufficient strength to support it without deformation after molding, thereby ensuring the overall reliability of the two-color decorative panel 100.

[0040] At the same time, by limiting the upper limit angle between the surface of the first end 211 of the second color part 2 away from the bottom wall of the groove 11 and the side wall of the groove 11 close to the first end 211, it is avoided that the angle between the surface of the first end 211 of the second color part 2 away from the bottom wall of the groove 11 and the side wall of the groove 11 close to the first end 211 is too large, which leads to a decrease in the strength of the groove 11, thereby ensuring the structural strength of the first color part 1 and thus ensuring the overall reliability of the two-color decorative panel 100.

[0041] Specifically, the angle between the surface of the first end 211 of the second color piece 2 facing away from the bottom wall of the groove 11 and the side wall of the groove 11 close to the first end 211 can be 80°, 90°, 100°, 110°, 120°, 130° or 135°.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the thickness of the second color member 2 gradually increases from the first end 211 to the second end 221 of the second color member 2, which is opposite the first end 211. It is understood that since the second color member 2 is an injection molded part, the gradual increase in thickness of the second color member 2 from the first end 211 to the second end 221 can reduce the flow resistance of the second color member 2 caused by sudden changes in cross-section during the injection molding process, allowing the melt to flow more smoothly. This effectively prevents stagnation or insufficient filling of the melt in thinner areas, and effectively avoids stress concentration caused by sudden cross-sectional changes or increased resistance, which can lead to localized whitening of the second color member 2 or a decrease in structural strength.

[0043] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the second color member 2 includes a transition section 21 and a uniform section 22 connected in sequence. The end of the transition section 21 facing away from the uniform section 22 is configured as a first end 211, and the end of the uniform section 22 facing away from the transition section 21 is configured as a second end 221. It can be understood that the smooth transition and reduced stress concentration of the transition section 21 optimize melt flow and filling effects, while the uniform section 22 maintains stable physical and mechanical properties, thereby improving the reliability and durability of the second color member 2, thereby improving the overall reliability of the two-color decorative panel 100.

[0044] In some embodiments of the present invention, the thickness of the transition section 21 is 2 mm. Thus, by limiting the size of the transition section 21, the resistance to melt flow can be reduced during the injection molding process, making it easier for the melt to flow from one end to the other, thereby ensuring the overall filling effect of the transition section 21.

[0045] In some embodiments of the present invention, the thickness of the uniform section 22 is 2.5 mm to 3 mm. This dimensioning allows the uniform section 22 to reduce resistance to melt flow during the injection molding process, allowing the melt to flow more easily from one end to the other, thereby ensuring a complete filling effect for the uniform section 22. Specifically, the thickness of the uniform section 22 can be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3 mm.

[0046] In some embodiments of the present invention, the thickness of the transition section 21 is 2 mm, and the thickness of the uniform section 22 is 2.5 mm to 3 mm. Thus, in the direction from the first end 211 to the second end 221, this arrangement can achieve a gradual increase in the thickness of the second color element 2, avoiding the flow resistance caused by a sudden change in cross section that affects the fluid flow, thereby improving the reliability of the second color element 2.

[0047] In some embodiments of the present invention, the thickness of any two points on the bottom wall of the groove 11 is identical at 2 mm. This dimensioning reduces resistance to melt flow in the area of ​​the first color component 1 forming the groove 11 during the injection molding process, facilitating melt flow from one end to the other, thereby ensuring a complete filling effect for the transition section 21. Furthermore, the thickness of the first end 211 is determined by combining the identical 2 mm bottom wall thickness of the groove 11 with a:b ratio of 0.75:1-1.5:1.

[0048] In some embodiments of the present invention, the thickness of the first color component 1 outside the groove 11 remains constant and ranges from 2.5 mm to 3 mm. This dimensioning reduces resistance to melt flow during the injection molding process, facilitating melt flow from one end to the other, thereby ensuring a complete filling effect for the uniform section 22. Specifically, the thickness of the first color component 1 outside the groove 11 can be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3 mm.

[0049] In some embodiments of the present invention, the thickness of the area of ​​the first color part 1 outside the groove 11 is unchanged and is 2.5mm-3mm, the thickness of any two points on the bottom wall of the groove 11 is the same and is 2mm, and the thickness of the area of ​​the first color part 1 outside the groove 11 and the bottom wall of the groove 11 are uniformly transitioned. Therefore, through such a setting, the flow resistance of the first color part 1 caused by sudden cross-sectional changes during the injection molding process can be reduced, so that the melt can flow more smoothly, thereby effectively avoiding stagnation or insufficient filling of the melt in thinner areas, and effectively avoiding the melt encountering sudden cross-sectional changes or increased resistance to cause stress concentration, resulting in local whitening or decreased structural strength of the first color part 1, thereby improving the reliability of the first color part 1.

[0050] The following describes a vehicle according to an embodiment of the present invention.

[0051] The vehicle according to the embodiment of the present invention includes a two-color decorative panel 100 .

[0052] According to an embodiment of the present invention, a vehicle is provided with a two-color decorative panel 100. The two-color decorative panel 100 is an injection-molded part. A first color component 1 has a groove 11, and a second color component 2 is positioned within the groove 11. Because a first end 211 of the second color component 2 extends beyond the surface of the first color component 1 having the groove 11, the second color component 2 is injected before the first color component 1. This prevents the melt of the first color component 1 from seeping into the second color component 2 during subsequent injection molding of the first color component 1, thereby preventing color bleeding. Furthermore, the first end 211 has a thickness a, and the bottom wall of the groove 11 opposite the first end 211 has a thickness b, where a:b = 0.75:1-1.5:1. This ensures sufficient injection pressure on the first color component 1 from the first end 211, preventing deformation, whitening, or water ripples after the first end 211 is supported and molded. This reduces the injection molding cycle and cost of the second color component 2, thereby improving the overall quality and durability of the two-color decorative panel 100 and reducing the cost of the vehicle.

[0053] Optionally, the two-color decorative panel 100 of the present application can be used as a taillight decorative panel of a vehicle.
