Description

[Technical Field]

[0001] The present invention relates to a vehicle exterior part, a vehicle illumination unit, and a method for manufacturing a vehicle exterior part. [Background technology]

[0002] For example, Patent Document 1 discloses an illumination grille equipped with a light source. In such an illumination grille, the illumination grille is illuminated by light emitted from the light source. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-75283 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, passenger cars have also been equipped with vehicle illumination units that can illuminate vehicles at night and other times. For example, such vehicle illumination units can be configured to include a light source that emits light and a vehicle exterior component that is disposed beyond the light source and transmits only a portion of the light from the light source. Vehicle exterior components that are visible from outside the vehicle often require three-dimensional decoration. To achieve such three-dimensional decoration, a concave portion can be formed in a portion of the back surface of a transparent member, and a thin metal layer can be formed on the inner wall surface of the concave portion. Meanwhile, it is preferable to prevent the light source portion from being visible from outside the vehicle exterior component during the day. Therefore, a colored translucent layer can be formed on the portion of the back surface of the transparent member outside the concave portion where the metal layer is not provided.

[0005] When manufacturing a vehicle exterior part that includes a metal layer provided in a recess of such a transparent member and a colored light-transmitting layer provided outside the recess, it is possible to insert a mask into the recess to form the colored light-transmitting layer, and then remove the mask to form the metal layer. However, when forming the colored light-transmitting layer by inserting a mask into the recess, tiny gaps are created between the inner wall surface of the recess and the mask, making it difficult to prevent the colored light-transmitting layer from infiltrating into the inner wall surface of the recess. If the colored light-transmitting layer infiltrates into the inner wall surface of the recess, the edges of the colored light-transmitting layer appear to be blurred from the outside, which detracts from the appearance.

[0006] Furthermore, when a light-shielding layer that blocks light from the light source unit is provided so as to avoid the recess, it is also possible to form the light-shielding layer by inserting a mask into the recess. However, in such a case, a small gap occurs between the inner wall surface of the recess and the mask, making it difficult to prevent the light-shielding layer from entering the inner wall surface of the recess. If the light-shielding layer enters the inner wall surface of the recess, light cannot pass through the edge of the recess, resulting in a poor appearance.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to prevent a decline in the appearance impression of vehicle exterior parts and illumination units that have a recess on the back surface of a transparent member and can be illuminated by transmitting a portion of the light from a light source unit. [Means for solving the problem]

[0008] The present invention employs the following configuration as a means for solving the above problems.

[0009] A first aspect of the present invention is an exterior part for a vehicle, comprising: a transparent member having a recess formed in a portion of its back surface; a metal layer formed on an inner wall surface of the recess; a colored light-transmitting layer that covers the metal layer from the side opposite the transparent member and is formed throughout the interior of the recess, and is formed on the back surface of the transparent member including a portion where the metal layer is not formed; and a light-shielding member that is connected to the transparent member with the colored light-transmitting layer sandwiched therebetween and has an opening.

[0010] A second aspect of the present invention is the first aspect, wherein the colored light-transmitting layer covers the entire back surface of the transparent member.

[0011] A third aspect of the present invention employs a configuration in which, in the first or second aspect, the light blocking member includes a main body portion that covers the recess, and a filling portion that fills the recess.

[0012] A fourth aspect of the present invention is a vehicle illumination unit comprising a vehicle exterior part according to any one of the first to third aspects, and a light source unit that emits light toward the vehicle exterior part.

[0013] A fifth aspect of the present invention is a method for manufacturing a vehicle exterior part, the method comprising the steps of: a transparent member forming step of forming a transparent member having a recessed portion in a portion of a back surface; a mask placing step of placing a mask that covers the back surface except for the recessed portion; a metal layer forming step of adhering a metal layer to the back surface of the transparent member via the mask; a mask removing step of removing the mask; a colored light-transmitting layer forming step of forming a colored light-transmitting layer that covers the entire inside of the recessed portion by covering the side opposite the transparent member with the metal layer and that is provided on the back surface of the transparent member including a portion where the metal layer is not provided; and a light-shielding member connecting step of connecting a light-shielding member that is formed separately from the transparent member and has an opening to the transparent member via the colored light-transmitting layer.

[0014] A sixth aspect of the present invention is the fifth aspect, wherein in the colored light-transmitting layer forming step, the colored light-transmitting layer is formed so as to cover the entire back surface of the transparent member.

[0015] A seventh aspect of the present invention, in the fifth or sixth aspect, employs a configuration in which the light-shielding member connected to the transparent member in the light-shielding member connecting step includes a filling portion that fills the recess. [Effects of the Invention]

[0016] According to the present invention, a metal layer is provided on the inner wall surface of the recess. The colored light-transmitting layer is provided on the entire interior of the recess, covering the metal layer from the side opposite the transparent member, and is also provided on the back surface of the transparent member, including the area where the metal layer is not provided. Therefore, when providing the metal layer and the colored light-transmitting layer, it is not necessary to insert a mask into the recess. Furthermore, because the colored light-transmitting layer is provided so as to cover the back surface of the metal layer, the colored light-transmitting layer is not visible inside the recess from the outside of the transparent member. Therefore, according to the present invention, the colored light-transmitting layer is prevented from being visible as if it is bleeding around the edge of the recess, thereby preventing a deterioration in the appearance. Furthermore, according to the present invention, a light-shielding member separate from the transparent member is connected to the transparent member. Therefore, the light-shielding member can be formed separately from the transparent member, and when providing a light-shielding member having an opening aligned with the recess, it is not necessary to insert a mask into the recess. Therefore, according to the present invention, it is possible to prevent a portion of the light-shielding member from entering the interior of the recess located at the opening, thereby preventing a deterioration in the appearance.

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle exterior part, a vehicle illumination unit, and a method for manufacturing a vehicle exterior part according to the present invention will be described below with reference to the drawings.

[0019] (First embodiment) 1 is a schematic diagram showing the general configuration of a vehicle illumination unit 100 according to this embodiment. As shown in this figure, the vehicle illumination unit 100 according to this embodiment is mounted on a vehicle and includes a vehicle exterior component 10 and a light source unit 20.

[0020] The vehicle exterior part 10 is disposed on the outer side of the vehicle relative to the light source unit 20, and is a part that is directly visible from outside the vehicle. The vehicle exterior part 10 includes a transparent member 1, a metal layer 2, a colored light-transmitting layer 3, and a light-shielding member 4.

[0021] The transparent member 1 is disposed at the outermost part of the vehicle exterior part 10. The transparent member 1 is formed by, for example, injection molding using a mold. For example, the transparent member 1 is formed from a transparent synthetic resin such as transparent PC (polycarbonate) or PMMA (polymethyl methacrylate resin).

[0022] In this embodiment, the transparent member 1 is formed in a plate shape. One surface of the transparent member 1 is a design surface 1a that is arranged facing the outside of the vehicle. Note that the design surface referred to here is not limited to a surface on which a pattern, lettering, or the like is directly formed, but may be any surface that is visible to those outside the vehicle. In other words, the design surface 1a is the outer wall surface of the transparent member 1. If necessary, the design surface 1a of such a transparent member 1 is subjected to a hard coat treatment or a clear coat treatment with urethane paint to prevent scratches. Note that if the transparent member 1 is made of a transparent synthetic resin that is scratch-resistant, these scratch-prevention treatments are not necessary.

[0023] The surface of the transparent member 1 opposite the design surface 1a is the back surface 1b. As shown in FIG. 1, a recess 1c is provided in a part of the back surface 1b of the transparent member 1. In this embodiment, two recesses 1c are provided in the back surface 1b of the transparent member 1. The number of recesses 1c can be changed. These recesses 1c are formed so as to be recessed from the back surface 1b of the transparent member 1 toward the design surface 1a. The part of the back surface 1b of the transparent member 1 where no recess 1c is provided is referred to as a shelf portion 1d. As shown in FIG. 1, this shelf portion 1d is a flat portion.

[0024] The metal layer 2 is provided on the inner wall surface of the recess 1c of the transparent member 1. The metal layer 2 is made of a metal material and has a thickness that allows a portion of the light emitted from the light source unit 20 to transmit therethrough. For example, the metal layer 2 can be made of indium (In) or aluminum (Al). For example, by forming the metal layer 2 by sputtering or vacuum deposition using indium (In), the metal layer 2 becomes capable of transmitting radio waves.

[0025] In this embodiment, the metal layer 2 is provided so as to cover the entire inner wall surface of the recess 1c. When the metal layer 2 is viewed from the outside (the side of the design surface 1a), an outsider can visually recognize the metal layer 2 as a three-dimensional metal.

[0026] The colored light-transmitting layer 3 can transmit a portion of the light emitted from the light source unit 20. The colored light-transmitting layer 3 is colored. Therefore, the light emitted from the light source unit 20, transmitted through the colored light-transmitting layer 3, and emitted from the design surface 1a is visually recognized as having the color tone of the colored light-transmitting layer 3. Therefore, when light is emitted from the light source unit 20, an outsider will visually recognize the area where the light from the light source unit 20 is emitted to the outside through the colored light-transmitting layer 3 as if the area is glowing.

[0027] Furthermore, the colored light-transmitting layer 3 reflects a portion of light. Therefore, when external light incident from the design surface 1a is reflected by the colored light-transmitting layer 3, the reflected light appears to have the color tone of the colored light-transmitting layer 3. Therefore, in areas where the colored light-transmitting layer 3 is visible when viewed from the design surface 1a side, an outsider is prevented from viewing the back side of the colored light-transmitting layer 3.

[0028] There is no particular limitation on the color tone of the colored light-transmitting layer 3. For example, the color tone of the colored light-transmitting layer 3 can be black. By making the color tone of the colored light-transmitting layer 3 black, the colored light-transmitting layer 3 functions like a smoke film.

[0029] The light-blocking member 4 is a member that blocks light, and is provided separately from the transparent member 1. For example, this transparent member 1 has enough strength to maintain its shape even when not connected to the light-blocking member 4. Such a light-blocking member 4 is connected to the transparent member 1 by, for example, adhesion or welding. Alternatively, the light-blocking member 4 and the transparent member 1 may be connected to the transparent member 1 by engaging or fastening.

[0030] As shown in Fig. 1, openings 4a are partially provided in the light blocking member 4. In this embodiment, as shown in Fig. 1, the light blocking member 4 has three openings 4a. Each opening 4a penetrates from the light source unit 20 side to the design surface 1a side, and allows light emitted from the light source unit 20 to pass through.

[0031] 1, in this embodiment, one of the openings 4a is arranged to overlap one of the recesses 1c when viewed from the design surface 1a side. In this manner, in the area where the openings 4a and the recesses 1c overlap when viewed from the design surface 1a side, when light is not emitted from the light source unit 20, the metal layer 2 appears to have a natural metallic luster when viewed from the outside due to external light. Furthermore, in this manner, in the area where the openings 4a and the recesses 1c overlap when viewed from the design surface 1a side, when light is emitted from the light source unit 20, the light emitted from the light source unit 20 passes through the thin metal layer 2, and the metal layer 2 appears to be shining brightly.

[0032] 1, in the area where the opening 4a and the shelf 1d overlap as viewed from the design surface 1a side, the colored light-transmitting layer 3 appears colored due to external light when viewed from the outside when no light is emitted from the light source 20. When no light is emitted from the light source 20, the shelf 1d appears colored due to the colored light-transmitting layer 3 when viewed from the outside, regardless of the presence or absence of the opening 4a.

[0033] 1, one of the recesses 1c is arranged so as not to overlap with the opening 4a when viewed from the design surface 1a side. In this manner, in a portion where the opening 4a and the recess 1c do not overlap when viewed from the design surface 1a side, the metal layer 2 does not appear to be shining brightly even when light is emitted from the light source unit 20. Note that even in a portion where the opening 4a and the recess 1c do not overlap when viewed from the design surface 1a side, the metal layer 2 appears to have a natural metallic luster when exposed to external light.

[0034] The light source unit 20 is disposed closer to the inside of the vehicle than the vehicle exterior part 10, and is capable of emitting light toward the vehicle exterior part 10. For example, the light source unit 20 emits light in response to an instruction from the driver or at a preset time.

[0035] Next, a method for manufacturing the vehicle exterior part 10 of this embodiment will be described with reference to Figures 2 and 3. Figures 2 and 3 are schematic diagrams showing the manufacturing process for the vehicle exterior part 10 of this embodiment.

[0036] First, as shown in FIG. 2(a), a transparent member 1 is formed having a recess 1c in a part of the back surface 1b. The step shown in FIG. 2(a) is a transparent member forming step. In the transparent member forming step, the transparent member 1 is formed by, for example, injection molding. By providing a protrusion that forms the recess 1c on a mold used for injection molding, the transparent member 1 can be formed in a single injection molding.

[0037] Next, as shown in FIG. 2(b), a mask M is placed to cover the back surface 1b of the transparent member 1 except for the recessed portion 1c. Here, the mask M, which has an opening M1 aligned with the recessed portion 1c, is superimposed on the back surface 1b of the transparent member 1. Also, as shown in FIG. 2(b), a metal layer 2 is formed and adhered to the back surface 1b of the transparent member 1 through the mask M. Here, a material X for forming the metal layer 2 is formed on the back surface 1b of the transparent member 1 by sputtering or vacuum deposition. Note that the process shown in FIG. 2(b) is a combined process of a mask placement process and a metal layer formation process.

[0038] 2(b) does not have a protrusion, but only has an opening M1. In other words, the mask M is not placed inside the recess 1c. Therefore, there is no unintentional minute gap between the mask M and the inner wall surface of the recess 1c.

[0039] Next, as shown in Fig. 2(c), the mask M is removed. The step shown in Fig. 2(c) is a mask removal step. As shown in Fig. 2(c), by removing the mask M, the metal layer 2 remains only on the inner wall surface of the recess 1c.

[0040] Next, as shown in FIG. 3(d), a colored light-transmitting layer 3 is formed. Here, the colored light-transmitting layer 3 is provided over the entire interior of the recess 1c, covering the metal layer 2 from the side opposite the transparent member 1. The colored light-transmitting layer 3 is also provided on the back surface 1b of the transparent member 1, including the area where the metal layer 2 is not provided (shelf portion 1d). In this embodiment, the colored light-transmitting layer 3 is formed so as to cover the entire back surface 1b, including the area where the metal layer 2 is formed (the inner wall surface of the recess 1c). The process shown in FIG. 3(d) is a colored light-transmitting layer forming process.

[0041] Next, as shown in Fig. 3(e), a light-shielding member 4 is prepared separately from the transparent member 1. The light-shielding member 4 is formed, for example, by injection molding, and has an opening 4a. Such a light-shielding member 4 can be formed in parallel with the steps shown in Figs. 2(a) to 2(c) and 3(d).

[0042] Next, as shown in Fig. 3(f), the light-shielding member 4 is connected to the transparent member 1. Here, the light-shielding member 4, which is formed separately from the transparent member 1 and has an opening, is connected to the transparent member 1 with the colored light-transmitting layer 3 sandwiched therebetween. Such a step shown in Fig. 3(f) is a light-shielding member connecting step.

[0043] The vehicle exterior part 10 of this embodiment as described above includes a transparent member 1, a metal layer 2, a colored light-transmitting layer 3, and a light-blocking member 4. The transparent member 1 has a recess 1c formed in a portion of its back surface 1b. The metal layer 2 is provided on the inner wall surface of the recess 1c. The colored light-transmitting layer 3 is provided over the entire interior of the recess 1c, covering the metal layer 2 from the side opposite the transparent member 1. The colored light-transmitting layer 3 is also provided on the back surface 1b of the transparent member 1, including a portion (shelf portion 1d) where the metal layer 2 is not provided. The light-blocking member 4 is connected to the transparent member 1 with the colored light-transmitting layer 3 sandwiched therebetween, and has an opening 4a.

[0044] According to the vehicle exterior part 10 of this embodiment, the metal layer 2 is provided on the inner wall surface of the recess 1c. The colored light-transmitting layer 3 is provided throughout the interior of the recess 1c, covering the metal layer 2 from the side opposite the transparent member 1, and is also provided on the back surface 1b of the transparent member 1, including the area where the metal layer 2 is not provided. Therefore, when providing the metal layer 2 and the colored light-transmitting layer 3, it is not necessary to insert a mask M into the recess 1c. Furthermore, because the colored light-transmitting layer 3 is provided so as to cover the back surface 1b side of the metal layer 2, the colored light-transmitting layer 3 cannot be seen inside the recess 1c from the outside of the transparent member 1. Therefore, according to the vehicle exterior part 10 of this embodiment, the colored light-transmitting layer 3 is prevented from being seen to bleed around the edge of the recess 1c, making it possible to prevent a deterioration in the appearance impression.

[0045] Furthermore, according to vehicle exterior part 10 of this embodiment, light-shielding member 4, which is separate from transparent member 1, is connected to transparent member 1. Therefore, light-shielding member 4 can be formed separately from transparent member 1, and when providing light-shielding member 4 having opening 4a aligned with recess 1c, there is no need to insert mask M into recess 1c. Therefore, vehicle exterior part 10 of this embodiment prevents part of light-shielding member 4 from entering the interior of recess 1c located at opening 4a in a way that is visible from the outside, and it is possible to prevent a deterioration in the appearance impression.

[0046] Furthermore, in the vehicle exterior part 10 of this embodiment, the colored light-transmitting layer 3 covers the entire back surface 1b of the transparent member 1. This prevents the light source unit 20 from being visible through the transparent member 1 at any point.

[0047] The vehicle illumination unit 100 of this embodiment includes the above-described vehicle exterior part 10 and a light source unit 20 that emits light toward the vehicle exterior part 10. Therefore, the vehicle illumination unit 100 of this embodiment can prevent the appearance impression of the vehicle exterior part 10 from being impaired.

[0048] Furthermore, the manufacturing method for the vehicle exterior part 10 of this embodiment includes a transparent member forming step, a mask arranging step, a metal layer forming step, a mask removing step, a colored light-transmitting layer forming step, and a light-shielding member connecting step. The transparent member forming step forms a transparent member 1 having a recess 1c formed in a portion of the back surface 1b. The mask arranging step arranges a mask M that covers the back surface 1b except for the recess 1c. The metal layer forming step adheres and forms a metal layer 2 on the back surface 1b of the transparent member 1 through the mask M. The mask removing step removes the mask M. The colored light-transmitting layer forming step forms a colored light-transmitting layer 3 that covers the metal layer 2 from the side opposite the transparent member 1 and is provided throughout the interior of the recess 1c, and is provided on the back surface 1b of the transparent member 1 including the portion where the metal layer 2 is not provided. The light-shielding member connecting step connects a light-shielding member 4 formed separately from the transparent member 1 and having an opening 4a to the transparent member 1 via the colored light-transmitting layer 3 therebetween.

[0049] According to the manufacturing method for the vehicle exterior part 10 of this embodiment, the metal layer 2 is provided on the inner wall surface of the recess 1c. The colored light-transmitting layer 3 is provided throughout the interior of the recess 1c, covering the metal layer 2 from the side opposite the transparent member 1, and is also provided on the back surface 1b of the transparent member 1, including the area where the metal layer 2 is not provided. Therefore, when providing the metal layer 2 and the colored light-transmitting layer 3, it is not necessary to insert a mask M into the recess 1c. Furthermore, because the colored light-transmitting layer 3 is provided so as to cover the back surface 1b side of the metal layer 2, the colored light-transmitting layer 3 is not visible inside the recess 1c from the outside of the transparent member 1. Therefore, according to the manufacturing method for the vehicle exterior part 10 of this embodiment, the colored light-transmitting layer 3 is prevented from being visible as if it is bleeding around the edge of the recess 1c, which makes it possible to prevent a deterioration in the appearance impression.

[0050] Furthermore, according to the manufacturing method for vehicle exterior part 10 of this embodiment, a light-shielding member 4 that is separate from transparent member 1 is connected to transparent member 1. This allows light-shielding member 4 to be formed separately from transparent member 1, and when providing a light-shielding member 4 having an opening 4a that matches recess 1c, there is no need to insert a mask M into recess 1c. Therefore, according to the manufacturing method for vehicle exterior part 10 of this embodiment, it is possible to prevent part of light-shielding member 4 from entering the interior of recess 1c located at opening 4a in a way that is visible from the outside, and to prevent a deterioration in the appearance impression.

[0051] Furthermore, in the manufacturing method for the vehicle exterior part 10 of this embodiment, the colored light-transmitting layer 3 is formed in the colored light-transmitting layer forming step so as to cover the entire back surface 1b of the transparent member 1. This prevents the light source unit 20 from being visible through the transparent member 1 at any point.

[0052] (Second embodiment) Next, a second embodiment of the present invention will be described with reference to Fig. 4. In the description of this embodiment, the description of the same parts as those in the first embodiment will be omitted or simplified.

[0053] 4 is a schematic diagram showing the overall configuration of a vehicle exterior part 10A of this embodiment. As shown in FIG. 4, in the vehicle exterior part 10A of this embodiment, the light-shielding member 4 includes a main body portion 40 and an embedded portion 41.

[0054] The main body 40 has the same flat plate shape as the light-shielding member 4 of the first embodiment. The embedded portion 41 is provided to protrude from the main body 40 toward the transparent member 1. This embedded portion 41 is inserted into one of the recesses 1c to fill the interior of the recess 1c.

[0055] In this embodiment, the entire inner wall surface of the recess 1c is covered with the metal layer 2, so the embedded portion 41 housed inside the recess 1c is not visible from the outside. According to the vehicle exterior part 10A of this embodiment, the interior of the recess 1c is embedded, so that no air layer is formed inside the recess 1c. This allows radio waves to pass through the recess 1c. Therefore, the vehicle exterior part 10A of this embodiment can be suitably used as a radar cover.

[0056] Furthermore, according to the manufacturing method for vehicle exterior part 10A of the present embodiment, by accommodating embedded part 41 in recess 1c in the light-shielding member connecting step, it is possible to easily and accurately position light-shielding member 4 relative to transparent member 1. Therefore, according to the manufacturing method for vehicle exterior part 10A of the present embodiment, it is possible to accurately connect light-shielding member 4 to transparent member 1.

[0057] While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to the above-described embodiments. The shapes and combinations of the components shown in the above-described embodiments are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present invention.

[0058] For example, in the above embodiment, the colored light-transmitting layer 3 covers the entire back surface 1b of the transparent member 1. However, the present invention is not limited to this. An opening may be partially provided in the colored light-transmitting layer 3.

[0059] In the second embodiment, the embedded portion 41 is a part of the light-shielding member 4. However, the present invention is not limited to this. For example, an embedded portion separate from the light-shielding member 4 may be embedded in the recess 1c. [Explanation of symbols]
