Description

Technical Field

[0001] The present invention relates to a light-transmitting panel for a vehicle.

Background Art

[0002] Patent Document 1 describes a decorative part applied to a vehicle such as an automobile. This decorative part includes a resin base material and a laminated film part laminated on the base material. The laminated film part has a design layer, a transparent layer, and a light-shielding layer.

[0003] The design layer is a translucent decorative layer that reflects light irradiated from the front surface while transmitting light from a lighting device irradiated from the back surface. The design layer is formed by printing a PU ink containing a pigment on the back surface of a support film for supporting the design layer, the transparent layer, and the light-shielding layer during the manufacture of the decorative part.

[0004] The transparent layer is a colorless and transparent layer that does not react to laser light. The transparent layer is formed by printing a PU ink containing no pigment such as carbon over the design layer. The light-shielding layer has a light-shielding part that blocks light and a laser processing part as a hole that transmits light from the lighting device. The light-shielding part includes a black mask layer that is a black opaque layer. The black mask layer is formed by printing a PU ink containing a pigment such as carbon over the transparent layer. The laser processing part is formed in a predetermined pattern shape in the light-shielding part by laser processing.

[0005] In such a decorative part, when the lighting device is turned off, light such as natural light irradiated from the front surface of the decorative part is reflected on the front surface of the design layer. Therefore, while the design of the design layer is visible from the front surface, the predetermined pattern formed by the laser processing part is difficult to see.

[0006] On the other hand, when the lighting device is turned on, the light irradiated by the lighting device from the back surface of the decorative part passes through the decorative part from the back surface to the front surface. Therefore, the predetermined pattern can be seen from the front surface.

[0007] [Patent Document 1] Japanese Patent Publication No. 2023-102872 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] However, the following problem arises with these decorative parts when the lighting is turned off. Specifically, because the design layer is configured to transmit light from the lighting, some of the light emitted from the surface of the decorative part passes through the design layer and reaches the light-shielding portion. In this case, the light-shielding portion is visible from the surface, and the part of the decorative part's surface that overlaps with the light-shielding portion may appear darker than other parts. As a result, the appearance of the decorative part deteriorates when the lighting is turned off.

[0009] Furthermore, these problems are not limited to light-transmitting panels such as decorative parts having the laser-processed parts described above, but can also occur in light-transmitting panels in which light-transmitting holes are formed by screen printing. [Means for solving the problem]

[0010] This document describes various embodiments of light-transmitting panels for vehicles that address the above-mentioned problems. [Aspect 1] A light-transmitting panel for a vehicle that covers a light source from the outside and has a resin substrate layer that is transparent to visible light, and a decorative layer laminated on the surface of the substrate layer, and which emits light outward by transmitting visible light emitted from the light source, wherein the decorative layer comprises a first color-emitting layer that transmits and reflects visible light, and a concealing layer laminated on the back side of the first color-emitting layer, and the concealing layer comprises a concealing portion having a light-shielding layer that blocks the transmission of visible light, and a second color-emitting layer that transmits and reflects visible light and produces the same or similar color as the first color-emitting layer, and a light-transmitting portion surrounded by the concealing portion that transmits visible light, and the second color-emitting layer is laminated between the first color-emitting layer and the light-shielding layer, the light-transmitting panel for a vehicle.

[0011] According to this configuration, when the light source is turned on, the visible light emitted from the light source is transmitted outward through the substrate layer, the light-transmitting portion of the opaque layer, and the first color-emitting layer, causing a predetermined pattern formed by the light-transmitting portion to be illuminated.

[0012] Furthermore, when the light source is not illuminated, visible light such as natural light shining onto the light-transmitting panel from the outside is reflected by the first color-emitting layer, causing the light-transmitting panel to be visible in a color corresponding to the color emitted by the first color-emitting layer.

[0013] Incidentally, some of the visible light irradiated onto the light-transmitting panel from the outside passes through the first color-generating layer and reaches the concealing layer. In this configuration, the concealing portion of the concealing layer has a second color-generating layer between the first color-generating layer and the light-shielding layer. Therefore, visible light that passes through the first color-generating layer and reaches the concealing portion is reflected by the second color-generating layer, making it difficult for it to reach the light-shielding layer. In other words, the fact that the light-shielding layer is visible from the outside suppresses the darkening of the portion of the light-transmitting panel that overlaps with the light-shielding layer.

[0014] On the other hand, if, for example, the second color-developing layer develops into a color different from and not similar to the first color-developing layer, the following problem arises. That is, because the second color-developing layer is visible from the outside, the aforementioned portion may be perceived in a color different from the desired color developed by the first color-developing layer. In this regard, according to the above configuration, the second color-developing layer develops into the same or a similar color as the first color-developing layer. Therefore, the second color-developing layer is less visible from the outside. This suppresses the possibility of the aforementioned portion being perceived in a color different from the color developed by the first color-developing layer.

[0015] Therefore, it is possible to suppress the deterioration of the appearance of the light-transmitting panel when the light source is not illuminated. [Aspect 2] A light-transmitting panel for a vehicle that covers a light source from the outside and has a resin substrate layer that is transparent to visible light, and a decorative layer laminated on the surface of the substrate layer, wherein the decorative layer transmits visible light emitted from the light source and displays light outwards, wherein the decorative layer comprises a first color-emitting layer that transmits and reflects visible light, and a concealing layer laminated on the back side of the first color-emitting layer, the concealing layer comprises a concealing portion having a light-shielding layer that blocks the transmission of visible light and a white layer that reflects and diffuses visible light, and a light-transmitting portion surrounded by the concealing portion that transmits visible light, the white layer being laminated between the first color-emitting layer and the light-shielding layer, the light-transmitting panel for a vehicle.

[0016] According to this configuration, when the light source is turned on, the visible light emitted from the light source is transmitted outward through the substrate layer, the light-transmitting portion of the opaque layer, and the first color-emitting layer, causing a predetermined pattern formed by the light-transmitting portion to be illuminated.

[0017] Furthermore, when the light source is not illuminated, visible light such as natural light shining onto the light-transmitting panel from the outside is reflected by the first color-emitting layer, causing the light-transmitting panel to be visible in a color corresponding to the color emitted by the first color-emitting layer.

[0018] Incidentally, a part of the visible light irradiated from the outside onto the light transmission panel passes through the first color-emitting layer and reaches the concealment layer. Here, according to the above configuration, the concealed portion of the concealment layer has a white layer between the first color-emitting layer and the light-shielding layer. Therefore, the visible light that has passed through the first color-emitting layer and reached the concealed portion is efficiently reflected and diffused by the white layer. As a result, since the light-shielding layer can be seen through from the outside, it almost never happens that the portion of the light transmission panel overlapping with the light-shielding layer looks dark. Furthermore, since it is a white layer, even when seen through from the outside, it is suppressed that the above portion is visually recognized in a color different from the color of the first color-emitting layer that is desired. Therefore, it is possible to suppress a decrease in the appearance of the light transmission panel when the light source is turned off.

[0019] [Aspect 3] The first color-emitting layer is formed of a film, and the concealment layer is formed by screen printing on the back surface side of the first color-emitting layer, the light transmission panel for a vehicle according to [Aspect 1] or [Aspect 2].

[0020] According to the same configuration, a concealment layer having a concealed portion and a light-transmitting portion is formed by screen printing on the back surface side of the film-like first color-emitting layer. Thereby, the degree of freedom in the design of the concealed portion, that is, the degree of freedom in the design of the light-transmitting portion can be easily improved.

[0021] Also, according to the above configuration, compared with the case where a concealment layer consisting only of a concealed portion is formed by printing or the like on the back surface side of the first color-emitting layer and then a light-transmitting portion is formed by irradiating with a laser to remove a part of the concealment layer, the step of irradiating with a laser becomes unnecessary. Therefore, the light transmission panel can be easily formed.

Effects of the Invention

[0022] It is possible to suppress a decrease in the appearance of the light transmission panel when the light source is turned off.

Embodiment for Carrying Out the Invention

[0024] Hereinafter, referring to FIGS. 1 to 4, an embodiment of the light transmission panel for a vehicle will be described. Hereinafter, the front and rear in the front-rear direction of the vehicle 10 on which the light transmission panel 14 is provided will be simply described as the front and the rear, respectively. Also, the right and left sides in the vehicle width direction when viewed from the rear to the front of the vehicle 10 will be simply described as the right side and the left side. Note that the front portion 10A is symmetric in the front view. For this reason, hereinafter, for convenience of explanation, only the left side portion of the front portion 10A will be shown, and the description of the right side portion will be omitted.

[0025] As shown in FIG. 1, a bumper cover 11 that forms a part of the outer shell of the vehicle 10 is provided at the front portion 10A of the vehicle 10. The bumper cover 11 is provided with a through hole 11a that penetrates the bumper cover 11 in the front-rear direction. The through hole 11a of the present embodiment is located below the headlight 12. A light source 13 that emits visible light forward is provided inside the through hole 11a (see FIG. 3). The light source 13 is composed of a light emitting element such as a light emitting diode (LED: Light Emitting Diode), for example. A light transmission panel 14 is attached to the through hole 11a of the bumper cover 11 via an attachment portion not shown. The light transmission panel 14 forms a part of the outer shell of the vehicle 10 and covers the light source 13 from the front.

[0026] As shown in Figure 2, the design surface 14A of the light-transmitting panel 14 is composed of a display area 14a that displays a predetermined pattern facing the front of the vehicle, and a background area 14c that serves as the background other than the display area 14a. Figures 1 and 2 show the state of the light-transmitting panel 14 when the light source 13 is lit. In this embodiment, a pattern is illuminated and displayed in which multiple straight sections 14b extending in the vehicle width direction are arranged vertically with spacing between them.

[0027] As shown in Figure 3, the light-transmitting panel 14 comprises a decorative layer 20, an adhesive layer 30, and a base layer 40. Each component will be described in detail below. <Decorative layer> As shown in Figure 3, the decorative layer 20 is for decorating the light-transmitting panel 14 and has a film laminate 21 and an opacity layer 25. The film laminate 21 is made up of a laminate film in which multiple films are laminated together with an adhesive (not shown). The film laminate 21 has a top layer 22, a first color-developing layer 23, and a backer layer 24.

[0028] The top layer 22 is laminated and bonded to the surface 23a of the first coloring layer 23. The top layer 22 is a protective film that provides chipping resistance, weather resistance, etc. The top layer 22 is made of transparent resin. The top layer 22 is composed of, for example, polycarbonate or acrylic resin and is colorless and transparent.

[0029] The first color-developing layer 23 is a metallic-looking film formed by vapor-depositing a metal such as aluminum or indium onto the back surface of a film substrate (not shown). In this embodiment, the first color-developing layer 23 is formed by vapor-depositing aluminum. The first color-developing layer 23 develops a glossy silver color, for example. The first color-developing layer 23 is configured to reflect visible light while also having a certain degree of visible light transmittance.

[0030] The backer layer 24 is laminated and bonded to the back surface 23b of the first coloring layer 23. The backer layer 24 is a protective film for protecting the first coloring layer 23 during the molding of the base material layer 40, which will be described later. The backer layer 24 is made of transparent resin. The backer layer 24 is composed of, for example, polycarbonate or acrylic resin and is colorless and transparent.

[0031] As shown in Figure 3, the opacity layer 25 has an opacity portion 25A and a light-transmitting portion 25B. The opacity portion 25A is a portion with higher opacity than the film laminate 21 and the base material layer 40, and constitutes the background region 14c. The opacity portion 25A is laminated and bonded to the portion of the back surface 24b of the backer layer 24 that corresponds to the background region 14c in the front-to-back direction. The opacity portion 25A is composed of a laminate in which multiple printed layers formed by screen printing are laminated. The opacity portion 25A has a second color-developing layer 26, a first light-shielding layer 27, and a second light-shielding layer 28.

[0032] The second color-developing layer 26 transmits and reflects visible light and develops a color similar to that of the first color-developing layer 23. The second color-developing layer 26 is formed by printing an ink containing a coloring agent such as a dye or pigment of a similar color to that of the first color-developing layer 23 onto the back surface 24b of the backer layer 24. The second color-developing layer 26 is adjusted to develop a color, for example, light gray.

[0033] The first light-shielding layer 27 and the second light-shielding layer 28 block the transmission of visible light. Both light-shielding layers 27 and 28 are formed by first printing an ink containing a black pigment such as carbon black onto the back surface 26b of the second color-developing layer 26, and then further printing the same ink onto the back surface 27b of the formed first light-shielding layer 27.

[0034] The light-transmitting portion 25B is a hole surrounded by the concealed portion 25A. In this embodiment, multiple light-transmitting portions 25B are formed corresponding to each straight portion 14b. Multiple light-transmitting portions 25B constitute the display area 14a. The concealed layer 25 is configured to transmit visible light through the light-transmitting portions 25B.

[0035] <Adhesive layer> As shown in Figure 3, the adhesive layer 30 is laminated and bonded to the back surface of the decorative layer 20. The adhesive layer 30 is intended to improve adhesion between the base material layer 40 and the concealed portion 25A, and is composed of a well-known binder used in insert molding.

[0036] <Base material layer> As shown in Figure 3, the base layer 40 is laminated on the back surface of the decorative layer 20 via the adhesive layer 30. The base layer 40 is positioned at the rearmost part of the light-transmitting panel 14 and mainly constitutes the back surface of the light-transmitting panel 14. The base layer 40 is made of transparent resin. In this embodiment, the base layer 40 is made of, for example, polypropylene or polycarbonate. In addition, to suppress the transmission of visible light irradiated onto the light-transmitting panel 14 from the front through the light-transmitting portion 25B to the base layer 40, the base layer 40 may contain a well-known diffusing material that diffuses visible light. In this embodiment, the light-transmitting panel 14 is formed by injection molding the base layer 40 with the decorative layer 20, on which the adhesive layer 30 is printed, as an insert member.

[0037] <Operation of this embodiment> As shown in Figures 2 and 3, when the light source 13 is lit, the visible light emitted from the light source 13 is transmitted forward through the substrate layer 40, the multiple light-transmitting portions 25B of the concealing layer 25, and the decorative layer 20, causing the display area 14a, which is composed of the multiple light-transmitting portions 25B, to light up and be displayed (see Figure 2).

[0038] Furthermore, as shown in Figures 3 and 4, when the light source 13 is not illuminated, visible light irradiated onto the light-transmitting panel 14 from the front passes through the top layer 22 and is reflected by the first color-emitting layer 23. As a result, the light-transmitting panel 14 is visible as a glossy silver color corresponding to the color emitted by the first color-emitting layer 23.

[0039] Incidentally, some of the visible light irradiated onto the light-transmitting panel 14 from the front passes through the first color-developing layer 23 and the backer layer 24 and reaches the concealing layer 25. In this configuration, the concealing portion 25A of the concealing layer 25 has a second color-developing layer 26 between the backer layer 24 located on the back surface 23b side of the first color-developing layer 23 and the first light-shielding layer 27. Therefore, the visible light that passes through the first color-developing layer 23 and the backer layer 24 and reaches the concealing portion 25A is reflected by the second color-developing layer 26, making it difficult for it to reach the light-shielding layers 27 and 28. In other words, because the light-shielding layers 27 and 28 are visible from the front, the portion of the light-transmitting panel 14 that overlaps with the light-shielding layers 27 and 28 in the front-to-back direction does not appear dark.

[0040] On the other hand, if, for example, the second color-developing layer 26 develops into a color different from the first color-developing layer 23, and is not a similar color, the following problem arises. That is, because the second color-developing layer 26 is visible from the front, the above-mentioned portion may appear in a color different from the desired silver color developed by the first color-developing layer 23. In this regard, according to the above configuration, the second color-developing layer 26 develops into a gray color, which is similar to the first color-developing layer 23. Therefore, the second color-developing layer 26 is less visible from the front. As a result, the above-mentioned portion is less likely to appear in a color different from the silver color developed by the first color-developing layer 23. That is, as shown in Figure 4, the entire design surface 14A of the light-transmitting panel 14 will appear uniformly in the silver color developed by the first color-developing layer 23.

[0041] <Effects of this embodiment> (1) The light-transmitting panel 14 comprises a transparent resin substrate layer 40 that transmits visible light and a decorative layer 20 laminated on the surface of the substrate layer 40. The decorative layer 20 comprises a first color-developing layer 23 that transmits and reflects visible light and a concealing layer 25 laminated on the back surface 24b of the backer layer 24, which is the back surface 23b side of the first color-developing layer 23. The concealing layer 25 comprises a concealing portion 25A and a light-transmitting portion 25B. The concealing portion 25A comprises light-shielding layers 27, 28 that block the transmission of visible light and a second color-developing layer 26 that transmits and reflects visible light and develops a color similar to that of the first color-developing layer 23. The light-transmitting portion 25B is surrounded by the concealing portion 25A and transmits visible light. The second color-developing layer 26 is laminated between the backer layer 24, which is located on the back surface 23b side of the first color-developing layer 23, and the first light-shielding layer 27.

[0042] This configuration produces the effects described above. Therefore, it is possible to suppress the deterioration of the appearance of the light-transmitting panel 14 when the light source 13 is not lit. (2) The film laminate 21 including the first color-developing layer 23 is composed of multiple films laminated together. The opacity layer 25 is formed by screen printing on the back surface 24b of the backer layer 24 located on the back surface 23b side of the first color-developing layer 23.

[0043] With this configuration, a concealed layer 25 having a concealed portion 25A and a translucent portion 25B is formed by screen printing on the back surface 24b of the backer layer 24 located on the back surface 23b side of the first color-developing layer 23. This makes it easy to improve the design freedom of the concealed portion 25A, and thus the design freedom of the translucent portion 25B.

[0044] Furthermore, with the above configuration, compared to the case where a concealing layer 25 consisting only of the concealing portion 25A is formed on the back surface 24b by printing or the like, and then a part of the concealing layer 25 is removed by laser irradiation to form the light-transmitting portion 25B, the laser irradiation step is unnecessary. Therefore, the light-transmitting panel 14 can be easily formed.

[0045] (3) The concealed portion 25A has a first light-shielding layer 27 and a second light-shielding layer 28. With this configuration, the visible light emitted from the light source 13 is blocked more effectively compared to the case where the concealing portion 25A is composed of a second color-emitting layer 26 and a first light-shielding layer 27. Therefore, when the light source 13 is lit, the visible light that leaks through the concealing portion 25A into the background area 14c can be further suppressed, which would otherwise degrade the appearance of the light-transmitting panel 14.

[0046] (4) The film laminate 21 has a backer layer 24. With this configuration, when the base layer 40 is injection molded with the decorative layer 20 as an insert member, the first coloring layer 23 is protected by the backer layer 24 from the heat and flow pressure of the molten resin. Therefore, damage to the first coloring layer 23 during the molding of the base layer 40 can be suppressed.

[0047] <Example of changes> The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0048] The design surface 14A of the light-transmitting panel 14 is not limited to having a display area 14a consisting of a plurality of straight sections 14b as exemplified in this embodiment, and the pattern displayed by the display area 14a may be changed as appropriate. For example, such a pattern may consist of a plurality of dots arranged with space between them.

[0049] The light-transmitting panel 14 is not limited to being formed by injection molding a base layer 40 with a decorative layer 20 as an insert member, as illustrated in this embodiment. For example, it may be formed by bonding the decorative layer 20 to a pre-molded base layer 40 via an adhesive layer. In this case, the backer layer 24 can be omitted from the decorative layer 20.

[0050] The second color-developing layer 26 is not limited to being composed of a printed layer formed by printing ink as exemplified in this embodiment. For example, the second color-developing layer 26 may be a thin metal film formed on the back surface 24b of the backer layer 24 by sputtering.

[0051] With this configuration, by forming the metal thin film with the same metal material as the first color-developing layer 23, a second color-developing layer 26 that develops the same color as the first color-developing layer 23 can be obtained. As a result, the light-shielding layers 27 and 28 are visible from the front, which further suppresses the dark appearance of the portion of the light-transmitting panel 14 that overlaps with the light-shielding layers 27 and 28.

[0052] In this embodiment, the first color-developing layer 23 is exemplified as a glossy silver color, but any metallic-looking film with metallic luster may be used, and its color may be changed as appropriate. Furthermore, the first color-developing layer 23 is not limited to a metallic-looking film with metallic luster. For example, the first color-developing layer 23 may be made of a colored resin film without metallic luster. In these cases, the color of the second color-developing layer 26 is not limited to the gray exemplified in this embodiment, and may be changed as appropriate to match the color developed by the first color-developing layer 23. In particular, when the second color-developing layer 26 is a white layer, the following effects can be achieved.

[0053] In other words, with this configuration, the concealed portion 25A of the concealing layer 25 has a white layer between the first color-emitting layer 23 and the light-shielding layers 27 and 28. Therefore, visible light that passes through the first color-emitting layer 23 and reaches the concealed portion 25A is efficiently reflected and diffused by the white layer. As a result, the light-shielding layers 27 and 28 are visible from the front, so the portion of the light-transmitting panel 14 that overlaps with the light-shielding layers 27 and 28 does not appear dark. Furthermore, because it is a white layer, it is visible from the front, which also suppresses the appearance of the above portion as a different color from the desired color emitted by the first color-emitting layer 23. Therefore, the deterioration of the appearance of the light-transmitting panel 14 when the light source 13 is not lit can be further suppressed.

[0054] The concealed portion 25A may have an additional light-shielding layer in addition to the light-shielding layers 27 and 28. The second light-shielding layer 28 may be omitted from the concealed portion 25A.

[0055] The first color-developing layer 23 is not limited to being composed of a film as illustrated in this embodiment. For example, the first color-developing layer 23 may be composed of a coating film formed by applying paint to a transparent resin substrate. In this case, the backer layer 24 may be omitted. The top layer 22 may also be composed of a coating film, similar to the first color-developing layer 23. The opacity layer 25 may be formed by printing on the back surface of the substrate.

[0056] The light-transmitting panel according to the present invention is not limited to constituting a part of the outer shell of the front 10A of the vehicle 10, as illustrated in this embodiment, but can also be implemented, for example, as constituting the rear or side of the vehicle 10. Even in this case, the light-transmitting panel only needs to cover the light source 13 from the outside and transmit the visible light emitted from the light source 13 outwards. Here, "outwards" refers to the side away from the center of the vehicle 10 in the front-rear direction, vehicle width direction, etc.

[0057] The light-transmitting panel according to the present invention is not limited to being embodied as a so-called exterior member that constitutes a part of the outer shell of the vehicle 10, as exemplified in this embodiment. That is, the light-transmitting panel can also be embodied as an interior member that constitutes a part of the design surface of the passenger compartment of the vehicle 10.
