[0030] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0031] In the present application, the term "outer" refers to a direction generally away from a light source; the term "inner" refers to a direction generally toward a light source, which is opposite to the direction indicated by "outer".

[0032] Figure 1 A vehicle 1 according to an embodiment of the present application is schematically shown. Figure 1As shown, the vehicle 1 includes a plurality of interior trims, such as a dashboard 10, a ceiling 11, and a door panel 12. An optical trim 2 for the vehicle (hereinafter referred to as the optical trim 2) may be provided on any of these interior trims to enable the interior trim to display a specific optical effect as required. For simplicity, the technical solution of the present application is described below by taking an optical trim suitable for being provided on a door panel as an example.

[0033] The first embodiment of the optical decoration is described below.

[0034] Reference Figure 2 and Figure 3 The optical trim 2 of the first embodiment includes a bottom plate 21, a light source 22, a light-transmitting component 23, and an opaque light-shielding layer 24. The color of the light-shielding layer 24 matches the color of other interior trims of the vehicle to improve the sensory quality of the vehicle. In one embodiment, the light-shielding layer is black. Of course, the color of the light-shielding layer can also be any other appropriate color, which is not limited here.

[0035] The bottom plate 21 is configured as a receiving slot with an opening. The light-transmitting component 23 is connected to the bottom plate 21 and defines a chamber 201 together. The light source 22 is disposed in the chamber 201, and after the light source 22 is lit, the light emitted by the light source 22 will penetrate the light component 23 and be emitted outside the chamber 201.

[0036] The light source 22 may include a circuit board 222 and an LED lamp bead 221 disposed on the circuit board 222. The circuit board 222 is fixedly mounted on the base plate 21 (for example, by clamping or fixing by screws), so that the light source 22 is fixedly disposed on the base plate 21. In some embodiments, the number of the LED lamp beads 221 is two or more. In other appropriate cases, the number of the LED lamp bead 221 may also be one. The light source may also be any other appropriate light-emitting device, which is not limited here.

[0037] The light-transmitting component 23 includes a first lampshade 233 and a second lampshade 234 assembled together. In one embodiment, the first lampshade 233 and the second lampshade 234 are both made of light-transmitting plastic so that the light emitted by the light source 22 can pass through the light-transmitting component 23. The light-transmitting plastic can be, for example, polycarbonate (ie, PC), acrylic, etc.

[0038] Reference Figure 3 , Figure 4 and Figure 6The first lampshade 233 includes a first main body plate 231, and the first main body plate 231 has a first inner surface 231a facing the light source 22 and a first outer surface 231b facing away from the light source 22. The first inner surface 231a is a smooth plane. A first light-transmitting area 231c is provided on the first outer surface 231b, and a plurality of refractive surfaces 231d are provided in the first light-transmitting area 231c, and the normal directions of these refractive surfaces 231d (i.e., the directions perpendicular to the refractive surfaces 231d) are different from each other. In one embodiment, the sizes of these refractive surfaces are also different. From the overall point of view, these refractive surfaces 231d protrude from the first outer surface 231b, and the sizes of the protrusions are different from each other, so that the first light-transmitting area 231c forms a rough area.

[0039] Reference Figure 3 , Figure 5 and Figure 6 The second lampshade 234 includes a second body plate 232, and the first body plate 231 matches the second body plate 232. The second body plate 232 has a smooth second inner surface 232a facing the light source 22 and a smooth second outer surface 232b away from the light source 22.

[0040] When the first lampshade 233 and the second lampshade 234 are assembled together, the first outer surface 231b of the first main body plate 231 and the second inner surface 232 of the second main body plate 232 are arranged adjacent to each other, so that the second lampshade 234 is assembled outside the first lampshade 233. In this way, the first inner surface 231a of the first main body plate 231 of the first lampshade 233 forms the inner surface of the light-transmitting component 23; the second outer surface 232b of the second main body plate 232 of the second lampshade 234 forms the outer surface of the light-transmitting component 23.

[0041] like Figure 2 As shown, the light shielding layer 24 is provided with a first display area 241. A plurality of light-transmitting holes 241b are provided in the first display area 241 and these light-transmitting holes 241b form a first preset pattern 241a. Figure 6 As shown, the light shielding layer 24 is attached to the second outer surface 232b (i.e., attached to the outer surface of the light-transmitting component 23), so that the light shielding layer 24 is located outside the first light-transmitting area 231c, and the first display area 241 corresponds to the first light-transmitting area 231c. Since the second outer surface 232b is smooth (as described above), it is convenient to arrange the light shielding layer 24 on the second outer surface 232b.

[0042] When the light source 22 is not lit, the shading layer 24 is opaque and blocks the internal structure of the optical trim 2. The occupants can hardly see the internal structure of the optical trim 2 and can hardly distinguish the first preset pattern 241a on the shading layer 24. This makes the interior environment of the vehicle appear tidier and helps to improve the riding experience of the occupants.

[0043] like Figure 6 As shown, after the light source 22 is turned on, the light emitted by the light source 22 passes through the light-transmitting component 23 (i.e., through the first lampshade 233 and the second lampshade 234), and then shines out from the light-transmitting hole 241b on the light-shielding layer 24. In this way, the optical ornament 2 presents a first pattern corresponding to the first preset pattern 241a. The form of the first pattern (or, the first preset pattern 241a) can be determined according to actual needs, for example, it can be a starry sky, or it can be at least one of text, letters, numbers, symbols, graphics and indicators, etc., which is not limited here. In addition, when the light-shielding layer 24 is black, each light-transmitting hole is formed as a bright spot on the black background, which makes the first pattern appear more clearly.

[0044] Also like Figure 6 As shown in FIG. 1 , since the normal directions of the refractive surfaces 231d in the first light-transmitting area 231c are different from each other, the light irradiated on these refractive surfaces 231d will be refracted in different directions and generate refracted light 202 in different directions. The refracted light 202 is combed by the light-transmitting holes 241b on the light-shielding layer 24 and has different intensities in different directions. In this way, when the passenger changes the viewing angle of the optical ornament 2 (such as turning the head or moving the position), Figure 7a The first perspective A1 shown, Figure 7b The first perspective A2 and Figure 7c In the first viewing angle A3 shown in the figure, the occupants will see through these light holes 241b either the light source 22 itself or virtual images 223 of the light source 22 at multiple different positions in the optical trim 2, and the brightness of these virtual images 223 is different (for example, the brightness of the virtual image corresponding to the stronger refracted light is higher, and the brightness of the virtual image corresponding to the weaker refracted light is lower), and the virtual image 223 is also different from the brightness of the light source 22 itself. As a result, the occupants will feel that the first pattern presented by the optical trim 2 has a flickering effect that changes with the viewing angle, and this flickering effect does not need to control the brightness of the light source 22 itself to achieve. This improves the decorative effect of the optical trim 2.

[0045] In one embodiment, the distance between the second inner surface 232a and the first outer surface 231b is greater than or equal to 2mm and less than or equal to 5mm. In this way, the first pattern presented by the optical trim 2 has a better flickering effect with the change of viewing angle, and the thickness of the optical trim 2 is small, and it will not excessively occupy the space of the passenger compartment. If the distance between the second inner surface 232a and the first outer surface 231b is less than 2mm, the difference in the intensity of the refracted light 202 emitted from these light-transmitting holes 241b is small, resulting in a small difference in light and dark between each virtual image 223, and the flickering effect of the first pattern with the change of viewing angle will also be reduced. If the distance between the second inner surface 232a and the first outer surface 231b is greater than 5mm, the thickness of the optical trim 2 will be larger, resulting in the space of the passenger compartment being excessively occupied by the optical trim 2 and becoming narrow, which is not conducive to improving the riding experience of the passengers. Of course, the distance between the second inner surface 232a and the first outer surface 231b can also be set to other values ​​according to actual conditions.

[0046] In one embodiment, colored LED lamp beads can be used as light sources 22 to make the optical ornament present a colored first pattern, which further improves the decorative effect of the optical ornament 2. Of course, monochrome LED lamp beads can also be used as light sources according to actual conditions. In some other embodiments, the lighting or extinguishing of these LED lamp beads can also be controlled by appropriate programs to make the optical ornament present a dynamic first pattern, so as to further improve the decorative effect of the optical ornament 2. The control method of LED lamp beads is easy to implement by technicians in this field and will not be repeated here.

[0047] In one embodiment, at least some of the light-transmitting holes 241b have sizes that are different from each other. For example, the sizes of these light-transmitting holes 241b can be set to be randomly distributed within an appropriate range and different from each other. In this way, more refracted light is emitted from the light-transmitting holes with larger sizes, and less refracted light is emitted from the light-transmitting holes with smaller sizes. As a result, the brightness of the virtual image seen from the light-transmitting holes with larger sizes is larger, and the brightness of the virtual image seen from the light-transmitting holes with smaller sizes is smaller. In this way, when the occupants change the viewing angle, they will feel that the flickering effect of the first pattern presented by the optical ornament changes with the viewing angle more strongly. According to actual conditions, the sizes of the light-transmitting holes can also be set to be the same. As mentioned above, due to the refraction of light by different refractive surfaces, the occupants can still feel the flickering effect of the first pattern that changes with the viewing angle.

[0048] In one embodiment, each light-transmitting hole 241b is a circular hole, which facilitates the manufacture of the light-transmitting layer. Of course, the light-transmitting hole can also be configured as other shapes, such as an elliptical hole, a triangular hole, a polygonal hole, a four-pointed star hole, a five-pointed star hole, etc., to improve the flickering effect of the first pattern as the viewing angle changes, which can be determined according to actual conditions.

[0049] For the light-transmitting holes in the form of circular holes, the diameter of the light-transmitting holes 241b is greater than or equal to 0.2 mm and less than or equal to 4 mm. It is found that when the diameter of the light-transmitting holes is within this range, the brightness of the first pattern presented by the optical ornament is moderate and the flickering effect that changes with the viewing angle is also good. When the diameter of the light-transmitting holes is less than 0.2 mm, less refracted light is emitted from the light-transmitting holes, resulting in a dimmer first pattern presented by the optical ornament, which is not conducive to improving the decorative effect of the optical ornament. When the diameter of the light-transmitting holes is greater than 4 mm, more refracted light is emitted from each light-transmitting hole, so the brightness of the virtual image seen from each light-transmitting hole is higher. This results in a poor flickering effect of the first pattern presented by the optical ornament that changes with the viewing angle.

[0050] In some cases, for a plurality of different optical accessories, along the thickness direction of the light-transmitting component, the further the distance from the light-shielding layer to the first light-transmitting area is, the smaller the light-transmitting hole is configured to be. Of course, according to actual conditions, for a plurality of different optical accessories, along the thickness direction of the light-transmitting component, the further the distance from the light-shielding layer to the first light-transmitting area is, the larger the light-transmitting hole is configured to be, or the same or substantially the same.

[0051] In one embodiment, the shading layer 24 is implemented as a shading film, and the light-transmitting holes described above and the second preset pattern described below are pre-formed on the shading film. The shading film can be bonded to the second outer surface 232b of the second main body plate 232 of the second lampshade 234. Since the second outer surface 232b of the second main body plate 232 is smooth (as described above), the bonding operation of the shading film is facilitated. In other embodiments, the shading film can also be formed into a whole with the second lampshade through an in-mold insert injection molding process. In this way, when assembling the optical ornament 2, there is no need to perform the bonding operation of the shading film, which simplifies the assembly operation of the optical ornament 2. The in-mold insert injection molding process is well known to those skilled in the art and will not be described in detail here.

[0052] In another embodiment, the light-shielding layer 24 is a light-shielding coating formed on the second outer surface 232b of the second main body plate 232 of the second lampshade 234. For example, a light-proof paint can be sprayed onto the second outer surface 232b to form a paint layer, and then the light-transmitting holes described above and the second preset pattern described below are formed on the paint layer by laser engraving or the like, so that a light-shielding layer is formed on the second outer surface. In one embodiment, the paint can also be applied to the second outer surface by screen printing or other appropriate methods, which are not limited here. In one embodiment, the light-proof paint can be a paint or dye of black or other appropriate colors. Paints and dyes are well known to those skilled in the art and will not be described in detail here.

[0053] It should be understood that, according to actual conditions, the light shielding layer may be disposed on one of the first outer surface, the first inner surface, and the second inner surface in addition to being disposed on the second outer surface described above. The first light-transmitting area may be disposed on any one or more of the second inner surface, the second outer surface, and the first inner surface in addition to being disposed on the first outer surface described above, but the light shielding layer should be ensured to be located outside the first light-transmitting area so that the refracted light can pass through the light-transmitting hole on the light shielding layer, which will not be described in detail here.

[0054] Also like Figure 2 As shown, a transparent or translucent second display area 242 is also provided on the shading layer 24, and a transparent or translucent second preset pattern 242a is provided in the second display area 242. The second display area 242 is surrounded by the first display area 241, and the second preset pattern 242a is also surrounded by the first preset pattern 241a. In this way, after the light source 22 is lit, the light emitted by the light source 22 also passes through the second preset pattern 242a and irradiates, so that the optical ornament 2 simultaneously presents the first pattern and the second pattern corresponding to the second preset pattern 242a, and the second pattern is surrounded by the first pattern. It should be noted that at the second preset pattern 242a, the material of the shading layer remains intact (that is, the second preset pattern is not a hollow pattern formed on the shading layer). In this way, the second pattern displayed by the optical ornament 2 has almost no flickering effect that changes with the viewing angle. According to this arrangement, the second pattern is significantly different from the first pattern, and the second pattern and the first pattern do not overlap, so that the second pattern can be clearly displayed and attract the attention of the occupants. In this case, the second pattern can be different from the first pattern to display more important information, such as indication information, identification information, etc. Of course, the second pattern can also be any other appropriate pattern, such as graphics, flowers, numbers, words, letters, etc., which are not limited here.

[0055] It should also be understood that the second pattern and the first pattern may also deviate from each other in other forms, such as the second pattern and the first pattern being separated left and right, separated up and down, arranged diagonally, nested with each other, or distributed alternately along the circumferential direction, etc., which are not listed here one by one. The deviation of the second pattern from the first pattern can be achieved by changing the distribution of the first preset pattern (or the first display area) and the second preset pattern (or the second display area) on the light shielding layer, which is not repeated here.

[0056] Of course, in appropriate cases, multiple light-transmitting holes may be dispersedly arranged in the second preset pattern, so that the second pattern presents a twinkling effect of stars as the viewing angle changes. In other embodiments, the second preset pattern may also be a hollow pattern formed on the light-shielding layer or a pattern different from the first preset pattern composed of additional light-transmitting holes, so that the second pattern has a twinkling effect as the viewing angle changes.

[0057] Reference Figure 2 and Figure 4 , a smooth second light-transmitting area 231e is provided within the range of the first light-transmitting area 231c on the first lampshade 223 (that is, there is no refractive surface as described above in the second light-transmitting area 231e), and a smooth second light-transmitting area (not shown in the figure) is also provided on the smooth first inner surface 231a, the smooth second outer surface 232b and the smooth second inner surface 232a. These second light-transmitting areas correspond to the second preset pattern 242a (or the second display area 242) on the light-shielding layer 24. In this way, when the light emitted from the light source 22 passes through the light-transmitting component 23 and irradiates the second preset pattern 242a (or the second display area 242), refraction in multiple directions as described above hardly occurs (that is, light hardly scatters), which helps to make the second pattern display clearer and avoids the second pattern from flickering with changes in viewing angle, thereby further improving the decorative effect of the optical ornament 2.

[0058] In an embodiment not shown, the second preset pattern may also be set on the light-transmitting component, and accordingly, the second preset pattern may not be set in the second display area of ​​the shading layer. After the light source is turned on, the second preset pattern on the light-transmitting component will be projected onto the shading layer (or in the second display area) to form a second pattern. In this case, the shading layer protects the second preset pattern and prevents the second preset pattern from being damaged (for example, damaged by scratches). In some embodiments, the second preset pattern may be set in the area of ​​the second lampshade corresponding to the second display area (for example, on the second inner surface or second outer surface of the second main body plate of the second lampshade), or may be set in the smooth second light-transmitting area of ​​the first lampshade described above, or may be set on the first inner surface of the first main body plate of the first lampshade (at this time, the first lampshade is still provided with a smooth second light-transmitting area corresponding to the second preset pattern).

[0059] Of course, the same or different second preset patterns may be provided in the second display areas of the light-transmitting component and the light-shielding layer so that the optical ornament can display a more complex second pattern, which will not be elaborated here.

[0060] The following describes the assembly of the first lampshade 233 and the second lampshade 234 on the bottom plate 21.

[0061] like Figure 4 As shown, the first lamp cover 233 further includes a first connection hole 235 disposed at the edge of the first main body plate 231. Figure 5 As shown, the second lampshade 234 also includes a connecting rod 236 disposed at the edge of the second main body plate 232 and a threaded hole (not shown in the figure) disposed in the connecting rod 236. In addition, a second connecting hole (not shown in the figure) is disposed on the bottom plate 21.

[0062] When assembling the light-transmitting assembly 23 and the bottom plate 21 together, the first main body plate 231 of the first lampshade 233 and the second main body plate 232 of the second lampshade 234 can be firstly attached together (as described above), and the connecting rod 236 on the second lampshade 234 is inserted into the corresponding first connecting hole 235 on the first lampshade 233 to complete the assembly of the light-transmitting assembly 23. Then, the threaded hole of the connecting rod 236 is aligned with the corresponding second connecting hole on the bottom plate 21, and screws are installed in the threaded hole and the second connecting hole, so that the light-transmitting assembly 23 and the bottom plate 21 are fixedly installed together, and the first lampshade 233 and the second lampshade 234 are also fixedly matched together.

[0063] In other embodiments, the first lampshade, the second lampshade and the bottom plate may also be assembled together in other ways, such as welding them together, which will not be described in detail here.

[0064] Next, a second embodiment of the optical decoration will be described.

[0065] Reference Figure 3 , Figure 8 and Fig. 9 The optical ornament of the second embodiment is similar to the optical ornament of the first embodiment in structure, and the main difference is that the light-transmitting component of the optical ornament 2 of the second embodiment only includes a third lampshade 25. The third lampshade 25 includes a third inner surface 251 facing the light source 22 and a third outer surface 252 facing away from the light source 22 (such as Fig.10 The third inner surface 251 is provided with the first light-transmitting area 231c as described above. The third outer surface 252 is a smooth surface and the light-shielding layer 24 as described above is attached to the third outer surface 252.

[0066] like Fig.10 As shown, similar to the optical ornament of the first embodiment, after the light source 22 is turned on, the optical ornament 2 of the second embodiment will display a first pattern, and the first pattern has a flickering effect that changes with the viewing angle, and this flickering effect does not require controlling the brightness of the light source 22 to be achieved.

[0067] Compared with the optical ornament of the first embodiment, the light-transmitting component of the optical ornament of the second embodiment has a simple structure, which reduces the manufacturing cost of the optical ornament of the second embodiment; and the thickness of the optical ornament of the second embodiment can be smaller than that of the optical ornament of the first embodiment, so as to reduce the encroachment of the optical ornament on the space of the passenger compartment.

[0068] Also similar to the optical ornament of the first embodiment, a smooth second light-transmitting area (not shown in the figure) is also provided on the third inner surface 251 of the third lampshade 25. The second light-transmitting area deviates from the first light-transmitting area 231c and corresponds to the second preset pattern on the light-shielding layer 24. Similar to the optical ornament of the first embodiment, after the light source 22 is turned on, the optical ornament 2 of the second embodiment will display the first pattern and the second pattern at the same time.
