The present invention relates to a decorative molded article and a method for manufacturing the decorative molded article, and particularly relates to a decorative molded article that allows transmitting a radio wave and illuminating a specific portion and a method for manufacturing the same.
Conventionally, as described in Patent Document 1 (JP 5132656 B), for example, a decorative member referred to as an emblem is attached to a vehicle. As such a decorative member, there is a decorative molded article manufactured by injection-molding a thermoplastic member. When the emblem attached to a front portion of the vehicle is attached in front of a radar device, a radio wave with a wavelength of from 1 mm to 10 mm, which is referred to as a millimeter wave, is required to pass through the emblem.
The decorative member of Patent Document 1 is formed of a material through which the millimeter wave transmitted and received by the radar device and visible light for decoration are allowed to pass.
However, the decorative member itself does not have a function of guiding light so as to illuminate a specific portion of the decorative member. Therefore, in Patent Document 1, a configuration in which a light emitting device of the decorative member includes a light guide plate that guides light to a specific portion and a case body having a reflecting surface, independently of the light emitting device, is employed. To provide the light guide plate and the reflecting surface, the light emitting device becomes a large scale and the decorative member and the light emitting device are expensive, and thus a space required for the decorative member and the light emitting device increases. To change a color of the transmission light, it is necessary to change a color of a light source or color a transmission portion. It is difficult to adjust a subtle tint by the light guide plate and the reflecting surface.
An object of the present invention is to provide a decorative molded article that allows easily adjusting a tint of light that illuminates a specific portion and illuminating the specific portion of the decorative molded article with a simple system.
Some aspects will be described below as means to solve the problems. These aspects can be combined randomly as necessary.
A decorative molded article according to one aspect of the present invention is a decorative molded article that transmits a radio wave handled by a wireless device that performs at least one of transmission and reception of a radio wave. The decorative molded article illuminates a specific portion by a light irradiated from a light emitting device. The decorative molded article includes a molded body, a decorative sheet, a first reflective layer, and a first coloring unit. The molded body is formed into a predetermined shape. The molded body contains a translucent polymer that allows transmitting a radio wave and transmitting the light from the light emitting device. The decorative sheet is bonded to a front surface of the molded body simultaneously with molding. The first reflective layer is formed so as to have a first opening portion in a back surface of the molded body. The first reflective layer reflects a light incident from the first opening portion and transmits a radio wave. The first coloring unit transmits a radio wave and colors the light incident from the first opening portion to generate a first colored light. The decorative sheet includes a translucent film and a shielding layer. The translucent film transmits a radio wave and a light. The shielding layer is fixedly secured to the translucent film, transmits a radio wave, and shields the first colored light. The shielding layer has a second opening portion. The second opening portion is arranged in the specific portion of the translucent film to take out the first colored light from the molded body to a front of the front surface.
Here, the radio wave refers to an electromagnetic wave generated by inverting a current in a conductor at 10 kHz to 3000 GHz.
In the decorative molded article configured in this manner, for example, the light from the light emitting device is incident from the first opening portion in the back surface of the molded body that has been molded, the light advances into the translucent polymer of the molded body, and the light is taken out from the second opening portion in the shielding layer of the decorative sheet bonded to the front surface of the molded body to the front of the front surface of the molded body. The specific portion of the decorative molded article can be illuminated by the light taken out from the second opening portion. In addition, the light reflected by the first reflective layers provided on the back surface of the molded body such that the light advances into the translucent polymer is colored by the first coloring unit and becomes the first colored light. Thus, a light guide path can be formed by the translucent polymer of the molded body, the decorative sheet, and the first reflective layers, for example, this eliminates the need for providing the light guide plate and the reflective layer separately from the decorative molded article, and the system that illuminates the decorative molded article by the light emitting device can be simplified.
In the decorative molded article described above, the decorative sheet may include a second reflective layer formed between the molded body and the shielding layer. The second reflective layer may transmit a radio wave and reflect the first colored light reflected by the first reflective layer to the first reflective layer. In the decorative molded article configured in this manner, the first colored light is reflected by the second reflective layer to the first reflective layer, and thus an amount of light of the first colored light taken out from the second opening portion can be increased.
In the decorative molded article described above, the first coloring unit is preferably provided on a front surface of the molded body. The first coloring unit is preferably a first coloring layer of the decorative sheet that is fixedly secured to the translucent film, transmits a radio wave, and colors the light incident from the first opening portion to generate the first colored light. The decorative molded article configured in this manner allows the light to be colored by the first coloring layer of the decorative sheet, and therefore the configuration of the decorative molded article can be simplified.
The decorative molded article described above may include a second coloring unit. The second coloring unit may generate a second colored light. The first reflective layer may have a third opening portion different from the first opening portion at a position where a light is guided to the second coloring unit. In the decorative sheet, the shielding layer may be arranged such that the second colored light reflected by the first reflective layer is allowed to be taken out from the second opening portion to the front of the front surface. The decorative molded article configured in this manner can selectively illuminate the specific portion with the first colored light and the second colored light and can improve designability.
In the decorative molded article described above, a smoke portion that transmits a radio wave and has a transmittance lower than a transmittance of the molded body may be arranged on the second opening portion. The decorative molded article configured in this manner can make a boundary between the second opening portion and the shielding layer be less noticeable, and can improve the appearance.
In the decorative molded article described above, the decorative sheet may include a second reflective layer formed between the molded body and the shielding layer. The second reflective layer may transmit a radio wave and reflect the first colored light reflected by the first reflective layer to the first reflective layer. The decorative sheet may be provided such that the second reflective layer blocks the second opening portion and the second reflective layer may function as a smoke portion. In the decorative molded article configured in this manner, the second reflective layer can also function as the smoke portion of the second opening portion, and the structure of the decorative molded article in which the smoke portion is arranged on the second opening portion can be simplified.
A decorative molded article according to another aspect of the present invention is a decorative molded article that illuminates a specific portion by a light irradiated from a light emitting device and includes a molded body, a decorative sheet, a first reflective layer, and a first coloring unit. The molded body is formed into a predetermined shape. The molded body contains a translucent polymer that allows transmitting the light from the light emitting device. The decorative sheet is bonded to a front surface of the molded body simultaneously with molding. The first reflective layer is formed so as to have a first opening portion in a back surface of the molded body. The first reflective layer reflects a light incident from the first opening portion. The first coloring unit colors the light incident from the first opening portion to generate a first colored light. The decorative sheet includes a translucent film and a shielding layer. The translucent film transmits a light. The shielding layer is fixedly secured to the translucent film and shields the first colored light. The shielding layer has a second opening portion. The second opening portion is arranged in the specific portion of the translucent film to take out the first colored light from the molded body to a front of the front surface.
In the decorative molded article configured in this manner, for example, the light from the light emitting device is incident from the first opening portion in the back surface of the molded body that has been molded, the light advances into the translucent polymer of the molded body, and the light is taken out from the second opening portion in the shielding layer of the decorative sheet bonded to the front surface of the molded body to the front of the front surface of the molded body. The specific portion of the decorative molded article can be illuminated by the light taken out from the second opening portion. In addition, the light reflected by the first reflective layers provided on the back surface of the molded body such that the light advances into the translucent polymer is colored by the first coloring unit and becomes the first colored light. Thus, a light guide path can be formed by the translucent polymer of the molded body, the decorative sheet, and the first reflective layers, for example, this eliminates the need for providing the light guide plate and the reflective layer separately from the decorative molded article, and the system that illuminates the decorative molded article by the light emitting device can be simplified.
A method for manufacturing a decorative molded article according to one aspect of the present invention is a method for manufacturing a decorative molded article that transmits a radio wave handled by a wireless device that performs at least one of transmission and a reception wireless device of a radio wave and illuminates a specific portion by a light emitting device.

The decorative sheet includes: a translucent film, a first coloring layer, a shielding layer, and a second reflective layer. The translucent film transmits a radio wave and a light. The first coloring layer is fixedly secured to the translucent film, transmits a radio wave, and colors a light incident from the first opening portion to generate a first colored light. The shielding layer is fixedly secured to the translucent film, transmits a radio wave, and shields the first colored light. The second reflective layer is formed between the molded body and the shielding layer, transmits a radio wave, and reflects the first colored light reflected by the first reflective layer to the first reflective layer. The shielding layer has a second opening portion. The second opening portion is arranged in the specific portion of the translucent film to take out the first colored light from the molded body to a front of the front surface. In the method for manufacturing the decorative molded article described above, for example, the configuration in which the light from the light emitting device is incident from the first opening portion in the back surface of the molded body, the light advances into the translucent polymer of the molded body, and the light is taken out from the second opening portion in the shielding layer to the front of the front surface of the molded body can be manufactured by decoration simultaneously with molding using the decorative sheet bonded to the front surface of the molded body. Furthermore, the decorative molded article in which the light reflected by the first reflective layer and the second reflective layer provided on the back surface and the front surface of the molded body such that the light advances into the translucent polymer is colored by the first coloring layer and becomes the first colored light can be easily manufactured using the decorative sheet.

In addition, according to the method for manufacturing the decorative molded article according to the present invention, the decorative molded article according to the present invention can be easily manufactured.
As illustrated in
In addition, light is incident on the decorative molded article 10 from a light emitting device 5.
Since the vehicle 1 is also used at night, the decorative molded article 10 has a configuration in which a specific portion 15 is illuminated by the light emitting device 5. The specific portions 15 are locations indicated by hatchings of dots in
As illustrated in
The molded body 20 is mainly a member that determines the outer shape of the decorative molded article 10. Therefore, the molded body 20 is molded into the predetermined shape so as to provide the shape required for the decorative molded article 10. The molded body 20 is required to function to transmit the millimeter wave and function to transmit a light. The molded body 20 is a member manufactured by injection molding and is manufactured using a thermoplastic material made of a translucent polymer.
The decorative sheet 30 is bonded to a front surface 21 of the molded body 20 simultaneously with molding. The decorative sheet 30 is formed of a material that allows transmitting the millimeter wave.
The first reflective layer 40 is formed on a back surface 22 of the molded body 20. The first reflective layer 40 reflects light and transmits the millimeter wave. This first reflective layer 40 has a first opening portion 41. The first opening portion 41 is a portion where the first reflective layer 40 is not formed or when the first reflective layer 40 transmits a light due to the incident direction of the light, a portion where the light passes through the first reflective layer 40 and is guided to the molded body 20 can be regarded as the first opening portion. The case where the portion being able to be regarded as the first opening portion is a case where, for example, the first reflective layer 40 is formed by a film that reflects obliquely incident light and transmits vertically incident light.
The first coloring unit 50 transmits the millimeter wave and colors the light incident from the first opening portion 41 to generate the first colored light. The first colored light generated by the first coloring unit 50 is reflected by the first reflective layer 40 and advances into the molded body 20. The first colored light that has advanced into the molded body 20 goes through a second opening portion 32a and a fourth opening portion 33a and exits a shielding layer 32 to illuminate the specific portion 15.
The decorative sheet 30 includes a translucent film 31 that transmits a millimeter wave and a light and the shielding layer 32 that is fixedly secured to the translucent film 31, transmits the millimeter wave, and shields the first colored light. The shielding layer 32 has the second opening portion 32a arranged in the specific portion 15 of the translucent film 31. The second opening portion 32a is an opening portion for taking out the first colored light from the molded body 20 to the front of the front surface 21 of the molded body 20. For example, the second opening portions 32a are arranged at the positions of the specific portion 15 around the “ni” characters and the circular specific portion 15 illustrated in
The molded body 20 is molded by injection-molding a thermoplastic material made of a translucent polymer. The thermoplastic material constituting the molded body 20 includes, for example, a thermoplastic resin and a thermoplastic elastomer. Examples of the thermoplastic resin used for the molded body 20 include polycarbonate resin, acrylic resin, and ABS resin. When the specific portion 15 is arranged at the thermoplastic material to be illuminated, the thermoplastic material is required to transmit the millimeter wave and have translucency. Since the millimeter wave passes through the polycarbonate resin, the acrylic resin, and the ABS resin, the radar device 2 can transmit and receive the millimeter wave through the decorative molded article 10 including the molded body 20 made of these thermoplastic resins. Here, the case where the molded body 20 is made of only the translucent polymer is described. However, the molded body 20 may contain a material other than the thermoplastic material. For example, a ceramic or a glass that can transmit the millimeter wave can be insert-molded together with a translucent thermoplastic resin.
As illustrated in
The decorative sheet 30 includes the second reflective layer 33. The second reflective layer 33 is formed between the molded body 20 and the shielding layer 32 and reflects the first colored light passing through the millimeter wave and reflected by the first reflective layer 40 to the first reflective layer 40. The fourth opening portion 33a is formed in the second reflective layer 33. The fourth opening portion 33a is arranged at a position overlapping with the second opening portion 32a. The first colored light reflected by the first reflective layer 40 is radiated to the front of the molded body 20 through the second opening portion 32a and the fourth opening portion 33a.
The thickness of the translucent film 31 is generally selected from a range of, for example, from 10 μm to 500 μm. The thickness of the translucent film 31 is preferably from 15 μm to 100 μm to facilitate following the three-dimensional shape of the molded body 20.
For example, resin or elastomer is used for the translucent film 31. The translucent film 31 made of resin is selected from, for example, a resin film made of a polyester resin, a polyethylene terephthalate (PET) resin, an acrylic resin, a polycarbonate resin, a polybutylene terephthalate (PBT) resin, a triacetyl cellulose resin, a styrene resin, or an ABS resin, a multilayer film made of an acrylic resin and an ABS resin, or a multilayer film made of an acrylic resin and a polycarbonate resin. As the elastomer used for the translucent film 31, for example, a thermoplastic elastomer (TPE) can be used. The thermoplastic elastomer includes, for example, amide-based TPE (TPA), ester-based TPE (TPC), olefin-based TPE (TPO), styrene-based TPE (TPS), and urethane-based TPE (TPU).
The shielding layer 32 is a layer for shielding light. The shielding layer 32 may be configured to cover the entire circumference of the decorative molded article 10. For example, in a case where the side surface of the decorative molded article 10 is covered with the shielding layer 32, the decorative sheet 30 is molded by pre-forming such that the side surface of the decorative molded article 10 is covered with the decorative sheet 30. The shielding layer 32 is formed by, for example, performing gravure printing or screen printing on the translucent film 31. The materials forming the shielding layer 32 include, for example, resin, such as an acrylic resin, a vinyl chloride vinyl acetate copolymer resin, a thermoplastic urethane resin, or a polyester resin, and a pigment or dye that is added to the resin. The pigment and the dye that do not attenuate the millimeter wave are selected.
The second reflective layer 33 is made of, for example, white ink, indium vapor deposition, tin vapor deposition, retroreflective ink, or metal ink having millimeter wave permeability. With the use of white ink, retroreflective ink, or metal ink having the millimeter wave permeability, the second reflective layer 33 is formed by, for example, gravure printing or screen printing. The indium vapor deposition and the tin vapor deposition are performed using a vacuum vapor deposition method, for example.
Although not illustrated, an adhesive layer may be provided between the second reflective layer 33 and the molded body 20, and the second reflective layer 33 may function as an adhesive layer. For example, a thermoplastic resin can be used for the adhesive layer. The thermoplastic resin used for the adhesive layer includes a urethane resin, a polyester resin, a polyamide resin, an acrylic resin, and a vinyl chloride vinyl acetate copolymer resin. The adhesive layer exhibits adhesiveness by heat of a molten resin and improves the adhesion force with the molded body 20. The thickness of the adhesive layer is, for example, from 2 μm to 20 μm in the film thickness after drying.
The first reflective layer 40 is constituted of, for example, white ink, indium vapor deposition, tin vapor deposition, retroreflective ink, a metallic film, or another ink having millimeter wave permeability. With the use of white ink, retroreflective ink, or ink having millimeter wave permeability, the first reflective layer 40 is formed by, for example, gravure printing or screen printing. The indium vapor deposition and the tin vapor deposition are performed using a vacuum vapor deposition method, for example. The metallic film includes, for example, PICASUS (registered trademark) manufactured by TORAY INDUSTRIES, INC. In the case of the metallic film, the metallic film is bonded to the molded body 20 by insert molding during molding of the molded body 20.
In the first embodiment, the first coloring unit 50 is a first coloring layer 34 of the decorative sheet 30 provided on the front surface 21 of the molded body 20. The first coloring layer 34 is fixedly secured to the translucent film 31, transmits the millimeter wave, and colors the light incident from the first opening portion 41 to generate the first colored light. It is formed on the second reflective layer 33 of the decorative sheet 30 by, for example, gravure printing or screen printing. The materials constituting the first coloring layer 34 include, for example, a resin, such as an acrylic resin, a vinyl chloride vinyl acetate copolymer resin, a thermoplastic urethane resin, or a polyester resin, and a pigment or dye that is added to the resin. The pigment and the dye that do not attenuate the millimeter wave are selected.
