Description

[Technical Field]

[0001] The present disclosure relates to exterior vehicle accessories. [Background technology]

[0002] The vehicle exterior accessory can be attached to a vehicle. The vehicle exterior accessory includes a cover that covers an opening of a housing. The vehicle exterior accessory is arranged so that the cover is exposed to the outside of the vehicle. Because the cover is exposed to the outside of the vehicle, it is desirable to enhance the design of the cover.

[0003] To meet these demands, it is conceivable to form a base coat and a metallic coat as shown in Patent Document 1 on the surface of the cover located on the exterior of the vehicle. Specifically, an achromatic gray base coat containing a white pigment and a black pigment is formed on the surface of the cover located on the exterior of the vehicle. Then, a metallic coat containing a luster material is formed on the gray base coat. This metallic coat also contains a chromatic pigment for coloring.

[0004] When the base coating film and metallic coating film shown in Patent Document 1 are formed on the surface of a cover for a vehicle exterior part located on the outside of the vehicle in this way, the following effects can be obtained: Namely, when light from outside the vehicle is reflected by the metallic coating film and base coating film, the color of the reflected light can be given a sense of brilliance and depth to the appearance of the cover from outside the vehicle. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 4079468 Summary of the Invention [Problem to be solved by the invention]

[0006] If the base coating film and metallic coating film shown in Patent Document 1 are formed on the surface of a cover for a vehicle exterior part that faces the outside of the vehicle, it is possible to impart a sense of brilliance and depth to the appearance of the cover from the outside of the vehicle. However, even in this case, the cover will look dull from the outside of the vehicle at night, etc., because there is less light from outside the vehicle reflected by the base coating film and metallic coating film. [Means for solving the problem]

[0007] Next, various aspects of vehicle exterior parts that solve the above problems will be described. (Aspect 1) A vehicle exterior accessory having a cover that covers an opening of a housing and is positioned so that the cover is exposed to the outside of the vehicle, the cover comprising a transparent substrate layer that is capable of transmitting light from a light source disposed within the housing, and a coloring layer laminated in the thickness direction on the transparent substrate layer, the coloring layer comprising an exterior color layer and a color adjustment layer that emit different colors from each other, the color adjustment layer being positioned closer to the light source than the exterior color layer, and remaining white even when white light passes through the color adjustment layer and the exterior color layer.

[0008] According to the above configuration, when the light source is off, light from outside the vehicle is reflected by the exterior color layer, causing the color of the cover to be colored by the exterior color layer. On the other hand, when the light source is on, light from the light source is transmitted through the color adjustment layer and the exterior color layer. The color adjustment layer allows white light to remain white even when it passes through the color adjustment layer and the exterior color layer, so light from the light source that passes through the coloring layer in the cover can be colored differently from the color generated by the exterior color layer. This allows the color of the cover to be different when the light source is off, such as during the day, and when the light source is on, such as at night, thereby enhancing the design of the cover. Furthermore, when the light source is on, such as at night, light from the light source is transmitted through the coloring layer of the cover toward the outside of the vehicle. This makes the color of the cover more noticeable, even at night, thereby improving the appearance of the cover from the outside of the vehicle at night.

[0009] (Aspect 2) The vehicle exterior part according to (Aspect 1), wherein the color-developing layer includes a concealing layer positioned between the exterior color layer and the color-adjusting layer, and the concealing layer is formed of a smoke-based paint.

[0010] According to the above configuration, when light from outside the vehicle is reflected by the color-adjusting layer, the reflected light is blocked by the concealing layer, and therefore the reflected light is prevented from passing through the exterior color layer. Therefore, the reflected light is prevented from passing through the exterior color layer and affecting the color of the cover. Furthermore, the concealing layer can adjust the amount of light transmitted through the cover from the light source and can prevent the inside of the housing from being seen through the cover from outside the vehicle when the light source is not lit.

[0011] (Aspect 3) The vehicle exterior part according to embodiment 2, wherein the concealing layer contains a large number of luster materials. According to the above configuration, when light from outside the vehicle is reflected by the numerous lustrous materials in the concealing layer, the reflected light is transmitted through the exterior color layer, thereby imparting lustrous color to the cover, thereby improving the design of the cover in the vehicle exterior part.

[0012] (Aspect 4) The color-forming layer includes a color-adding layer that can transmit light from the light source, and the color-adding layer adds color to the light from the light source that passes through the color-adjusting layer and the exterior color layer. (Aspect 1) to (Aspect 3) A vehicle exterior part according to any one of the preceding claims.

[0013] According to the above configuration, when light from the light source passes through the color-adding layer, the color-adjusting layer, and the exterior color layer, the color of the color-adding layer is added to the light, which allows the cover to be colored in a color other than white, thereby improving the design of the cover in the vehicle exterior part.

[0014] (Aspect 5) The vehicle exterior part according to any one of (Aspect 1) to (Aspect 4), wherein the minimum values ​​of transmittance when the visible light wavelength is changed in the exterior color layer and the color-adjusting layer are the same.

[0015] According to the above configuration, the minimum values ​​of transmittance when the visible light wavelength is changed in the exterior color layer and the color adjustment layer are aligned, so that the light transmitted through the color adjustment layer and the exterior color layer can be made white.

[0016] (Aspect 6) The exterior color layer and the color-adjusting layer are configured so that the average transmittance of visible light transmitted through the exterior color layer and the color-adjusting layer within a wavelength range of 420 nm or more and 700 nm or less is 0.7 to 1.3 times the minimum transmittance of visible light transmitted through the exterior color layer within a wavelength range of 420 nm or more and 700 nm or less. (Aspect 1) to (Aspect 4) Vehicle exterior part according to any one of the above aspects.

[0017] According to the above configuration, the product of the transmittance of the exterior color layer for each wavelength band of visible light and the transmittance of the color-adjusting layer for each wavelength band of visible light, that is, the transmittance of the exterior color layer and the color-adjusting layer for each corresponding wavelength band of visible light, is a value that is fairly close for each wavelength band of visible light, thereby making it possible to make the light that has passed through the color-adjusting layer and the exterior color layer white.

[0019] [First embodiment] A first embodiment of a vehicle exterior accessory will be described below with reference to FIGS. The vehicle exterior accessory shown in FIG. 1 can be attached to a vehicle. The vehicle exterior accessory includes a housing 11, a cover 12, and a light source 13. The housing 11 has an opening. The cover 12 covers the opening of the housing 11. The light source 13 is disposed within the cover 12. An LED that emits white light, for example, can be used as the light source 13. When the vehicle exterior accessory is attached to a vehicle, the cover 12 of the vehicle exterior accessory is disposed so as to be exposed outside the vehicle, i.e., facing left in FIG. 1.

[0020] <Cover 12> As shown in Fig. 2, the cover 12 includes a transparent substrate layer 14 and a coloring layer 15. The transparent substrate layer 14 is capable of transmitting light from the light source 13 disposed within the housing 11. The coloring layer 15 is laminated in the thickness direction of the transparent substrate layer 14. Specifically, the coloring layer 15 is formed on the surface of the transparent substrate layer 14 that faces outside the vehicle, i.e., on the surface located on the left side of Fig. 2.

[0021] The color-forming layer 15 includes an exterior color layer 16, a concealing layer 17, and a color-adjusting layer 18. The exterior color layer 16 and the color-adjusting layer 18 are configured to develop colors different from each other. The color-adjusting layer 18 is located closer to the transparent substrate layer 14 than the exterior color layer 16, in other words, closer to the light source 13. The color-adjusting layer 18 is configured to remain white even when white light passes through the color-adjusting layer 18 and the exterior color layer 16.

[0022] The concealing layer 17 is located between the exterior color layer 16 and the color-adjusting layer 18. The concealing layer 17 is formed of a smoke-based paint. As a result, the concealing layer 17 blocks reflected light when light from outside the vehicle is reflected by the color-adjusting layer 18. The concealing layer 17 also contains a large number of luminous materials 19. The luminous materials 19 are formed of, for example, aluminum.

[0023] <Details of each layer in Cover 12> The exterior color layer 16 may contain, for example, a red pigment, so that when light from outside the vehicle is reflected by the exterior color layer 16 as shown by arrow Y1, it turns red. Light from outside the vehicle is reflected not only by the exterior color layer 16 but also by the concealing layer 17 as shown by arrow Y2. This allows the cover 12 to look brighter and more profound when viewed from outside the vehicle, in addition to the red color of the exterior color layer 16.

[0024] When a red-colored exterior color layer 16 is used, a green-colored color layer 18 is used so that white light remains white even when it passes through the color-adjusting layer 18 and the exterior color layer 16. That is, by including a green pigment in the color-adjusting layer 18, the color-adjusting layer 18 will develop a green color when light from outside the vehicle is reflected by the color-adjusting layer 18 as shown by arrow Y3. However, even if light from outside the vehicle is reflected by the color-adjusting layer 18, the reflected light is blocked by the concealing layer 17, and therefore the green color of the color-adjusting layer 18 is prevented from being seen from outside the vehicle.

[0025] FIG. 3 shows the change in transmittance of blue wavelength light, green wavelength light, and red wavelength light in white light when the white light passes through the color-adjusting layer 18, the concealing layer 17, and the exterior color layer 16 in that order.

[0026] As can be seen from FIG. 3, when white light passes through the color-adjusting layer 18, the blue and red wavelengths of light are absorbed, thereby reducing the transmittance of the blue and red wavelengths of light. As a result, the light after passing through the color-adjusting layer 18 becomes green. When this light passes through the concealing layer 17, the transmittance of the blue, green, and red wavelengths of light overall decreases. As a result, the light after passing through the concealing layer 17 also becomes green. When this light passes through the exterior color layer 16, the green wavelength of light is absorbed, thereby reducing the transmittance of the green wavelength of light to the transmittance of the blue and red wavelengths of light. As a result, the light after passing through the exterior color layer 16 becomes white.

[0027] In this way, when a red color-developing layer is used as the exterior color layer 16, by using a green color-developing layer as the color-adjusting layer 18, the white light remains white even when it passes through the color-adjusting layer 18 and the exterior color layer 16.

[0028] <Visible Light Transmittance of Color Adjusting Layer 18 and Exterior Color Layer 16> The visible light transmittance of the color-adjusting layer 18 and the exterior color layer 16 is adjusted as follows so that white light remains white even when it passes through the color-adjusting layer 18 and the exterior color layer 16.

[0029] The transmittance of red wavelength light in the exterior color layer 16 changes as shown by the solid line L1 in Figure 4 when the wavelength is changed. The minimum value M1 of the transmittance of red wavelength light in the exterior color layer 16 decreases as the proportion of red pigment contained in the exterior color layer 16 increases. On the other hand, the transmittance of green wavelength light in the color-adjusting layer 18 changes as shown by the solid line L2 in Figure 4 when the wavelength is changed. The minimum value M2 of the transmittance of green wavelength light in the color-adjusting layer 18 decreases as the proportion of green pigment contained in the color-adjusting layer 18 increases.

[0030] The proportion of red pigment contained in the exterior color layer 16 and the proportion of green pigment contained in the color-adjusting layer 18 are adjusted so that the minimum value M1 of the transmittance of red wavelength light in the exterior color layer 16 and the minimum value M2 of the transmittance of green wavelength light in the color-adjusting layer 18 are the same. This ensures that the amount of decrease in the transmittance of blue and red wavelength light when white light passes through the color-adjusting layer 18 shown in Figure 3 is the same as the amount of decrease in the transmittance of green wavelength light when light passes through the exterior color layer 16 shown in Figure 3. As a result, white light remains white even when it passes through the color-adjusting layer 18 and the exterior color layer 16.

[0031] Next, the effects of the vehicle exterior accessory of this embodiment will be described. (1-1) When the light source 13 is off, light from outside the vehicle is reflected by the exterior color layer 16, causing the color of the cover 12 to be colored by the exterior color layer 16. On the other hand, when the light source 13 is on, light from the light source 13 passes through the color-adjusting layer 18 and the exterior color layer 16 as shown by arrow Y4 in FIG. 2 . The color-adjusting layer 18 maintains white light even when it passes through the color-adjusting layer 18 and the exterior color layer 16. This allows the light from the light source 13 that passes through the color-forming layer 15 of the cover 12 to have a color different from the color generated by the exterior color layer 16. This allows the color of the cover 12 to be different when the light source 13 is off, such as during the day, and when it is on, such as at night, thereby improving the design of the cover 12. Furthermore, when the light source 13 is on, such as at night, light from the light source 13 passes through the color-forming layer 15 of the cover 12 toward the outside of the vehicle. This allows the color of the cover 12 to stand out even at night, etc., thereby improving the appearance of the cover 12 from outside the vehicle at night, etc.

[0032] (1-2) When light from outside the vehicle is reflected by the color-adjusting layer 18, the reflected light is blocked by the concealing layer 17, and therefore the reflected light is prevented from passing through the exterior color layer 16. This prevents the reflected light from passing through the exterior color layer 16 and affecting the color of the cover 12. Furthermore, the concealing layer 17 can adjust the amount of light from the light source 13 that passes through the cover 12, and can prevent the inside of the housing 11 from being seen through the cover 12 from outside the vehicle when the light source 13 is not lit.

[0033] (1-3) Light from outside the vehicle is also reflected by the concealing layer 17. The concealing layer 17 is formed from a smoke-based paint and contains a large number of lustrous materials 19. Therefore, when light from outside the vehicle is reflected by the concealing layer 17, the reflected light passes through the exterior color layer 16, thereby imparting a sense of depth and brilliance to the coloring of the cover 12 in addition to the red coloring provided by the exterior color layer 16. More specifically, the sense of depth is imparted by the smoke paint of the concealing layer 17. Furthermore, the brilliance is imparted by the reflection of light by the large number of lustrous materials 19 in the concealing layer 17. As a result, the design of the cover 12 in a vehicle exterior part is improved.

[0034] (1-4) By aligning the minimum value M1 of the transmittance of red wavelength light in the exterior color layer 16 with the minimum value M2 of the transmittance of green wavelength light in the color-adjusting layer 18, white light can remain white even when it passes through the color-adjusting layer 18 and the exterior color layer 16.

[0035] [Second embodiment] Next, a second embodiment of a vehicle exterior accessory will be described with reference to FIG. 5, the exterior color layer 16 of the cover 12 in the vehicle exterior accessory of this embodiment contains a black pigment so that light from outside the vehicle appears black when reflected by the exterior color layer 16. The proportion of black pigment contained in the exterior color layer 16 is adjusted to a value that allows white light to pass through the exterior color layer 16.

[0036] The cover 12 does not include the concealing layer 17 as in the first embodiment, and the color-developing layer 15 is formed by an exterior color layer 16 and a color-adjusting layer 18. Because the exterior color layer 16 contains a black pigment, when light from outside the vehicle is reflected by the color-adjusting layer 18, the reflected light is blocked by the exterior color layer 16. When white light passes through the exterior color layer 16, the light that has passed through the exterior color layer 16 may be colored due to components other than the black pigment in the exterior color layer 16. The color-adjusting layer 18 may contain a color, such as a green pigment, that causes the white light to remain white when it passes through the color-adjusting layer 18 and the exterior color layer 16.

[0037] According to this embodiment, the same effect as the effect (1-1) in the first embodiment can be obtained. [Third embodiment] Next, a third embodiment of a vehicle exterior accessory will be described with reference to FIGS.

[0038] In this embodiment, the transmittance of each wavelength band of visible light in the exterior color layer 16 and color-adjusting layer 18 of the first and second embodiments is adjusted so that white light from the light source 13 remains white light even when it passes through the color-adjusting layer 18 and the exterior color layer 16.

[0039] When white light from the light source 13, i.e., visible light, passes through the exterior color layer 16, the transmittance of each wavelength band of the visible light changes, for example, from the state shown in FIG. 6 to the state shown in FIG. 7. As a result, the light after passing through the exterior color layer 16 becomes, for example, red. On the other hand, when white light from the light source 13, i.e., visible light, passes through the color-adjusting layer 18, the transmittance of each wavelength band of the visible light changes, for example, from the state shown in FIG. 6 to the state shown in FIG. 8. As a result, the light after passing through the color-adjusting layer 18 becomes, for example, green.

[0040] In order for white light from the light source 13, i.e., visible light, to remain white when it passes through the color-adjusting layer 18 and the exterior color layer 16, it is possible to determine the transmittance of each wavelength band of visible light in the exterior color layer 16 and the transmittance of each wavelength band of visible light in the color-adjusting layer 18 as follows: That is, the product of the transmittances of the exterior color layer 16 and the color-adjusting layer 18 in corresponding wavelength bands should be set to values ​​that are reasonably close to each other for each wavelength band of visible light. In other words, when visible light passes through the exterior color layer 16 and the color-adjusting layer 18, the transmittances of the visible light in each wavelength band should be set to values ​​that are reasonably close to each other. More preferably, the transmittances of the visible light in each wavelength band should be equal, as shown in FIG. 9 .

[0041] In Figure 10, solid line L1 indicates the transmittance of each wavelength band of visible light in the wavelength range of 420 nm or more and 700 nm or less when the visible light passes through exterior color layer 16. Also in Figure 10, solid lines L2 to L4 indicate the transmittance of each wavelength band of visible light in the wavelength range of 420 nm or more and 700 nm or less when the visible light passes through exterior color layer 16 and color-adjusting layer 18. Solid lines L2 to L4 represent the transmittance of white light from light source 13, i.e., visible light that remains white when it passes through color-adjusting layer 18 and exterior color layer 16; more specifically, the transmittance of each wavelength band of visible light in the wavelength range of 420 nm or more and 700 nm or less.

[0042] As can be seen from the solid line L1 in Figure 10, the minimum transmittance for each wavelength band of visible light in the wavelength range of 420 nm to 700 nm when the visible light passes through the exterior color layer 16 is approximately 13% in this example. Meanwhile, the average transmittance values ​​indicated by the solid lines L2, L3, and L4 are within the range of 0.7 to 1.3 times the minimum value. Therefore, by adjusting the exterior color layer 16 and the color-adjusting layer 18 to achieve this, the white light from the light source 13, i.e., visible light, can remain white light when it passes through the color-adjusting layer 18 and the exterior color layer 16.

[0043] According to this embodiment, in addition to the effects (1-1) to (1-3) of the first embodiment, the following effects can be obtained. (3-1) The average transmittance of visible light transmitted through the exterior color layer 16 and the color-adjusting layer 18 for each wavelength band within the wavelength range of 420 nm to 700 nm is between 0.7 and 1.3 times the minimum transmittance of visible light transmitted through the exterior color layer 16 for each wavelength band within the wavelength range of 420 nm to 700 nm. That is, the exterior color layer 16 and the color-adjusting layer 18 are adjusted to achieve this. As a result, the product of the transmittance of the exterior color layer 16 for each wavelength band and the transmittance of the color-adjusting layer 18 for each wavelength band of visible light, i.e., the transmittance of the exterior color layer 16 and the color-adjusting layer 18 for each corresponding wavelength band, is relatively close for each wavelength band of visible light. This allows white light from the light source 13 to remain white when transmitted through the color-adjusting layer 18 and the exterior color layer 16.

[0044] [Other embodiments] The above-described embodiments can be modified, for example, as follows: The above-described embodiments and the following modifications can be combined with each other within the scope of technical compatibility.

[0045] In the first embodiment, the exterior color layer 16 does not necessarily have to emit red color, and may emit yellow or blue color, for example. If the exterior color layer 16 emits yellow color, the color-adjusting layer 18 can be made to emit blue color, so that white light remains white when it passes through the color-adjusting layer 18 and the exterior color layer 16. If the exterior color layer 16 emits blue color, the color-adjusting layer 18 can be made to emit red color, so that white light remains white when it passes through the color-adjusting layer 18 and the exterior color layer 16.

[0046] In the first embodiment, the light from the light source 13 that passes through the cover 12 when the light source 13 is turned on does not necessarily have to be white. For example, the color-producing layer 15 of the cover 12 may be provided with a color-adding layer that can transmit light from the light source 13, and the color-adding layer may add color to the light from the light source 13 that passes through the color-adjusting layer 18 and the exterior color layer 16. The color-adding layer contains a pigment that corresponds to the color to be added.

[0047] In this case, when light from the light source 13 passes through the color-adding layer, the color-adjusting layer 18, and the exterior color layer 16, the color of the color-adding layer is added to the light. This allows the color of the cover 12 to be a color other than white, improving the design of the cover 12 in a vehicle exterior accessory. The color-adding layer may be formed between the transparent substrate layer 14 and the color-adjusting layer 18, or may be formed on the surface of the transparent substrate layer 14 facing the light source 13.

[0048] In the first embodiment, the color-forming layer 15 may be laminated on the surface of the transparent substrate layer 14 facing the light source 13, i.e., the surface on the right side in Fig. 11, as shown in Fig. 11. The color-adjusting layer 18 of the color-forming layer 15 is located closer to the light source 13 than the exterior color layer 16. Furthermore, if the color-forming layer 15 includes the color-adding layer described above, it is possible to form the color-adding layer on the surface of the color-forming layer 15 facing the light source 13, relative to the color-adjusting layer 18.

[0049] In the second embodiment, the color-forming layer 15 may be formed on the surface of the transparent substrate layer 14 facing the light source 13. In this case, the color-adjusting layer 18 of the color-forming layer 15 is also located closer to the light source 13 than the exterior color layer 16.

[0050] In the first embodiment, the luster material 19 may be made of a material having luster other than aluminum. In the first embodiment, the masking layer 17 does not necessarily need to contain the luster material 19 .

[0051] In the first embodiment, the concealing layer 17 in the coloring layer 15 may be omitted. In the third embodiment, the exterior color layer 16 may be configured to develop a black color as in the second embodiment when light from outside the vehicle is reflected by the exterior color layer 16. In this case as well, the transmittance of each wavelength band of visible light in the exterior color layer 16 and the transmittance of each wavelength band of visible light in the color-adjusting layer 18 are determined so that the product of the transmittances of the exterior color layer 16 and the color-adjusting layer 18 in the corresponding wavelength bands is equal for each wavelength band of visible light.
