[0001] The invention relates to the technical field of automobile decorative parts, and in particular to an automobile lighting decorative part and a manufacturing method thereof. Background Art

[0002] At present, with the expansion of automobile demand, people are pursuing personalized interior decoration in addition to the intrinsic quality and shape. Both comfort and appearance must be perfect, which is the key factor for drivers and passengers to evaluate the comfort of the car. In order to reflect the personalized interior decoration, existing automobile interior decoration parts tend to use lighting products, which bring people a variety of visual and tactile experiences such as color changes, dazzling, warm and cozy.

[0003] Due to the characteristic of light propagation in a straight line, the existing patterns of lighting products are generally recognized as linear patterns. That is, the conventional practice is to set a light-transmitting panel in the car, and then use laser engraving or printing to transmit light on the back, and design a set of surface light sources on the back. There are problems such as single lighting effect, square pattern, and complex structure of the lighting decoration. The corresponding production process has the defects of complex procedures and low qualified rate. Based on this, the present invention proposes a new automobile lighting decoration and its production method. Summary of the invention

[0012] Furthermore, the light source is a strip light bar arranged along the length direction of the reflector.

[0013] Furthermore, a plurality of light source points are arranged at intervals on the strip light bar.

[0014] Furthermore, the diameter of the circular concave / convex dots in the circular concave / convex dot array is 30 to 150 μm; and the distance between two adjacent concave / convex dots is 30 to 150 μm.

[0015] In a second aspect, the present invention provides a method for manufacturing the automotive lighting decoration as described in the first aspect, comprising the following steps:

[0016] S1. Forming a reflective plate according to a preset mold, wherein a plurality of circular concave / convex dot arrays arranged at intervals are formed on the surface of the reflective plate;

[0017] S2, installing the light source in the upper front or lower front area of ​​the reflector;

[0018] S3, sequentially installing an outer shell cover, a light-transmitting cover and a rear shell cover on the outer side of the reflector;

[0019] S4, lighting the light source through the switch, and the light of the light source is reflected by the circular convex dot array on the reflective plate into the field of view, presenting a light pattern; changing the distance and relative angle between the light source and the reflective plate can change the light pattern;

[0020] The circular concave / convex dot array on the reflective plate is used to reflect regular and intertwined arc light patterns.

[0021] Based on the above technical solution, the present invention can also be improved as follows.

[0022] Furthermore, step S1 is prepared by mold injection molding: a plurality of circular convex dot arrays arranged at intervals are processed on the mold; the reflector is formed by injection molding, and a circular concave dot array corresponding to the circular convex dot array is formed on the surface of the reflector.

[0023] Furthermore, step S1 is prepared by hot pressing a mold: a plurality of circular convex dot arrays arranged at intervals are processed on the mold, the template is heated to a preset temperature, and when the material substrate is heated to a softened state, the template is pressed down to form the reflective plate, and a circular concave dot array corresponding to the circular convex dot array is formed on the surface of the reflective plate.

[0026] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0027] The present invention provides an automobile lighting decoration and a manufacturing method thereof, wherein the automobile lighting decoration comprises: a reflector, an outer shell cover, a light-transmitting cover, a rear shell cover and a light source; the outer shell cover, the light-transmitting cover and the rear shell cover are arranged around the outer side of the reflector; the light-transmitting cover and the rear shell cover are respectively located at the front and rear sides; the light source is arranged on the side of the reflector facing the light-transmitting cover and is located in the upper front or lower front area of ​​the reflector; wherein a plurality of circular concave / convex dot arrays arranged at intervals are formed on the surface of the reflector; the circular concave / convex dot arrays on the reflector are used to reflect regular and mutually interwoven arc light patterns.

[0031] 3. The dots of the traditional light guide plate are about a few tenths of a millimeter in diameter. Because the dots are visibly shiny, a diffusion plate or diffusion film structure needs to be added to the surface. The present invention utilizes the circular concave / convex dots designed into a microscopic micron-level structure, which makes the light more delicate, so no diffusion structure is required.

[0032] 4. In the prior art, the light source is on the back or side of the optical structure, and the light is guided out through the optical structure. The present invention does the opposite, and designs the light source on the side of the human eye - in front of the lower part or the upper part of the reflector. By reflecting the light, a new lighting scheme is presented. Moreover, the light source is shielded by the lower edge structure of the outer cover shell, so that the light can be seen but not the light source.

[0033] 5. Usually, complex light patterns require complex optical structures to change the light path, and even need to use complex large thick-walled light guides to achieve them. However, it is still difficult to directly display curved light effects. The present invention has a simple structure and a breakthrough use of simple thin plates, plus microscopic circular concave or convex structures, to achieve complex and beautiful light patterns. Because the patterns are beautiful and regularly arranged, they have good commercial application value.

[0034] In summary, the automobile lighting decoration parts and the manufacturing method thereof provided by the present invention can effectively solve the defects existing in the prior art, so that the manufactured lighting decorations have beautiful lighting effects, regular patterns, and simple structures. The corresponding manufacturing process is simple and has a high pass rate, and has good and wide applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" 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 a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The following is combined with Figures 1 to 5 The embodiments of the present invention are further described in detail with examples. The following examples are used to illustrate the present invention but cannot be used to limit the scope of the present invention.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides an automobile lighting decoration, including: a reflector 1, an outer shell cover 2, a light-transmitting cover 3, a rear shell cover 4 and a light source 5.

[0047] The outer shell cover 2, the light-transmitting cover 3 and the rear shell cover 4 are arranged around the outer side of the reflector 1; the light-transmitting cover 3 and the rear shell cover 4 are located at the front and rear sides respectively.

[0048] The light source 5 is disposed on the side of the reflector 1 facing the light-transmitting cover 3 and is located in the upper front or lower front area of ​​the reflector 1. Figure 3 As shown, in an optional example, the light source 5 is located in the front and lower part of the reflective plate 1 .

[0049] The light source 5 is a strip light bar, arranged along the length direction of the reflector 1. Figure 1 As shown, a plurality of light sources 5 are arranged at intervals on the strip light bar.

[0050] A plurality of circular concave / convex arrays arranged at intervals are formed on the surface of the reflector 1. The circular concave / convex arrays on the reflector are used to reflect regular and intertwined arc light patterns.

[0051] Specifically, the diameter of the circular pits / convex points in the circular pit / convex point array is 30-150 μm; and the spacing between two adjacent pits / convex points is 30-150 μm.

[0052] The light source 5 is located at the lower front or upper front of the reflector 1 , and the corresponding reflection pattern is a positive arc or an inverted arc.

[0053] The reflective plate 1 can be a thin plate, and its function is to reflect a pattern by utilizing the refraction and reflection principle of light.

[0054] Through the combination of the circular concave / convex dot array and the light source 5 on the reflector 1, a breakthrough can be achieved in the beautiful lighting effect of regularly superimposing multiple curves. Because light propagates in a straight line, current lighting appearances are mainly square, with almost no curved lighting appearances (excluding external patterns such as laser engraving, in which the light source 5 at the bottom is still square). In this embodiment, the combination of the circular concave / convex dot array and the light source 5 on the reflector 1 can achieve a beautiful lighting effect of regularly superimposing multiple curves.

[0055] Furthermore, changing the distance or relative angle between the light source 5 and the reflector 1, or changing the microscopic circular concave dots into circular convex dots, can cause corresponding changes in the arc shape. These changing graphic schemes are all within the protection scope of the embodiments of the present invention. The specific settings are not limited, and adaptive pattern design can be performed according to actual needs.

[0056] In an optional embodiment, if Figure 2 and Figure 3 As shown, the outer shell cover 2 is provided with a lower edge structure, and the lower edge structure is used to shield the light source 5.

[0057] Specifically, in conventional designs, the light source is generally on the back or side of the optical structure, and the light is derived through the optical structure. However, in the embodiment of the present invention, the light source 5 is designed to be on the side of the human eye, that is, in front of the lower part or front of the reflector 1. By reflecting the light, a new lighting solution is achieved. Moreover, the light source 5 is blocked by the lower edge structure of the outer cover shell, so that the light can be seen but not the light source.

[0058] In summary, compared with the commonly complex light patterns in the prior art, complex optical structures are required to change the light path, and even complex large-scale thick-walled light guides are required to achieve this, but it is still difficult to directly display curved light effects. The automotive lighting decoration provided by the embodiments of the present invention has a breakthrough in using a simple thin plate, combined with a microscopic circular concave or convex structure, to achieve a complex and beautiful light pattern. Because of the beauty and regular arrangement of this pattern, it has obvious commercial application value.

[0059] Further, in order to better explain the automotive lighting decoration provided by the embodiment of the present invention, the manufacturing method thereof is provided below:

[0060] like Figure 6 The specific production process is as follows:

[0061] Step S1: A reflector is formed according to a preset mold, and a plurality of circular concave / convex dot arrays arranged at intervals are formed on the surface of the reflector.

[0062] The diameter of the circular concave / convex dots in the circular concave / convex dot array is 30-150 μm, and the spacing between two adjacent concave / convex dots is 30-150 μm. The specific size can be adaptively set according to actual needs and is not specifically limited here.

[0063] Furthermore, in actual operation, there are three ways to make the reflector:

[0064] Method 1: Preparation and formation by mold injection: a plurality of circular convex dot arrays arranged at intervals are processed on the mold; a reflector is formed by injection molding, and a circular concave dot array corresponding to the circular convex dot array is formed on the surface of the reflector.

[0065] Specifically, (1) a circular bump array with a diameter of 30 to 150 um and a spacing of 30 to 150 um is processed on the mold;

[0066] (2) forming a reflector by injection molding, wherein the reflector surface has a circular concave dot array microstructure with a diameter of 30 to 150 μm and a spacing of 30 to 150 μm;

[0067] (3) Install the light source above or below the reflector;

[0068] (4) Turn on the light source, and reflect the light from the light source through the circular concave dot array microstructure on the reflector, reflecting arc-shaped light patterns.

[0069] Method 2: Preparation and formation by mold hot pressing: the mold is processed with multiple circular convex arrays arranged at intervals, the template is heated to a preset temperature, and when the material substrate is heated to a softened state, the template is pressed down to form a reflective plate, and a circular concave array corresponding to the circular convex array is formed on the surface of the reflective plate.

[0070] The material substrate is organic glass material, polycarbonate plastic or glass plate.

[0071] Specifically, (1) a circular bump array with a diameter of 30 to 150 μm and a spacing of 30 to 150 μm is processed on the template, and the template is heated to a certain temperature;

[0072] (2) Select substrates made of materials such as PMMA, PC, and glass;

[0073] (3) heating the material substrate to a softened state, and pressing the template down to form a reflector, wherein a circular concave dot array microstructure with a diameter of 30 to 150 μm and a spacing of 30 to 150 μm is formed on the surface of the reflector;

[0074] Here the template can be round, the substrate moves continuously underneath, and is cut to the required size, forming an assembly line production;

[0075] (4) Then install the light source above or below the reflector;

[0076] (5) Turn on the light source, and reflect the light from the light source through the circular concave dot array microstructure on the reflector, reflecting arc-shaped light patterns.

[0077] Method 3: Preparation and formation by laser dotting: laser dotting is performed on the surface of the substrate by a laser to form a reflector having a plurality of circular concave dot arrays arranged at intervals.

[0078] As above, the substrate can be organic glass material, polycarbonate plastic or glass plate.

[0079] Specifically, (1) selecting a substrate of materials such as PMMA, PC, or glass;

[0080] (2) The surface of the substrate is dotted by laser to form a reflector, and a circular concave dot array microstructure with a diameter of 30 to 150 μm and a spacing of 30 to 150 μm is formed on the surface of the reflector;

[0081] (3) Install the light source above or below the reflector;

[0082] (5) Turn on the light source, and reflect the light from the light source through the circular concave dot array microstructure on the reflector, reflecting arc-shaped light patterns.

[0083] Step S2: Install the light source in the upper front area or the lower front area of ​​the reflector.

[0084] Step S3: installing the outer shell cover, the light-transmitting cover and the rear shell cover in sequence on the outer side of the reflector.

[0085] Step S4, lighting the light source through the switch, the light from the light source is reflected by the circular convex dot array on the reflective plate into the field of view, presenting a light pattern; changing the distance and relative angle between the light source and the reflective plate can change the light pattern.

[0086] The circular concave / convex dot array on the reflector is used to reflect regular and intertwined arc light patterns.

[0087] Light at a certain angle will be reflected into the human eye, so if Figure 4 and Figure 5 As shown, an arc-shaped light will be reflected on the reflector. When multiple light sources are designed, the reflector will reflect regular and intertwined arc-shaped light patterns. By adjusting the distance between the lamp beads, the density of the intertwining can be adjusted. The simple optical structure design realizes rich and beautiful lighting effects. Therefore, the automotive lighting decoration made in this embodiment enriches the functions of the lighting decoration.

[0088] It should be noted that in the above examples, circular concave dots are made on the surface of the reflective plate, but in other examples, the microscopic circular concave dots can be changed to circular convex dots according to the needs of the pattern, causing the arc shape to change accordingly to meet the needs of graphic diversity. Therefore, the design of circular concave dots and circular convex dots can fall within the scope of protection of the present invention.

[0089] In summary, compared with the prior art, this embodiment can achieve the following technical effects:

[0090] 1. The automotive lighting decoration and the manufacturing method thereof provided by the embodiments of the present invention achieve a breakthrough in achieving a beautiful lighting effect with regular superposition of multiple curves.

[0091] 2. The light guide plate of the traditional optical structure has the function of guiding light from one end to the other, while the reflective plate in the embodiment of the present invention has a circular concave / convex dot array, which uses the principle of refraction and reflection of light to reflect a pattern.

[0092] 3. The dots of a traditional light guide plate are about a few tenths of a millimeter in diameter. Because the dots are visibly shiny, a diffusion plate or diffusion film structure needs to be added to the surface. The embodiment of the present invention utilizes the circular concave / convex dots designed into a microscopic micron-level structure, which makes the light more delicate, so no diffusion structure is required.

[0093] 4. In the prior art, the light source is on the back or side of the optical structure, and the light is guided out through the optical structure. The embodiments of the present invention do the opposite, and design the light source on the side of the human eye - in front of the lower part or the upper part of the reflector. By reflecting the light, a new lighting scheme is presented, and the light source is shielded by the lower edge structure of the outer cover shell, so that the light can be seen but not the light source.

[0094] 5. Usually, complex light patterns require complex optical structures to change the light path, and even need to use complex large thick-walled light guides to achieve them. However, it is still difficult to directly display curved light effects. The present invention has a simple structure and a breakthrough use of simple thin plates, plus microscopic circular concave or convex structures, to achieve complex and beautiful light patterns. Because the patterns are beautiful and regularly arranged, they have good commercial application value.

[0095] In summary, the automobile lighting decoration parts and the manufacturing method thereof provided by the embodiments of the present invention can effectively solve the defects existing in the prior art, so that the manufactured lighting decoration parts have beautiful lighting effects, regular patterns, and simple structures, and the corresponding manufacturing process is simple with a high pass rate, and have good and wide applicability.
