Description

  The present invention relates to a vehicle member, and more particularly, to a vehicle member suitable for an ornament of an automobile or the like.

  In recent years, various radar systems have been mounted on vehicles (automobiles) for the purpose of improving safety and convenience. One example is radar cruise control. Radar cruise control irradiates millimeter wave radar from the radar sensor to the front of the vehicle and receives reflected waves from the preceding vehicle, recognizes the speed difference and inter-vehicle distance from the preceding vehicle, and automatically controls the running speed of the vehicle System.

  The radar sensor is hidden and arranged in an inconspicuous place such as the center of the front of the vehicle and the back of the front grille in consideration of the radar directivity. However, an ornament or a front emblem for displaying a CI (Corporate Identity) mark or the like is often arranged at the center of the front of the vehicle. For this reason, the arrangement position of the radar sensor and the ornament may overlap and the radio wave emission surface of the radar sensor may be covered by the ornament.

  The ornament is made of a metal or a material having a metallic luster in consideration of design properties. However, ornaments made of stainless steel or nickel plating absorb and diffuse radio waves entering and radiating the radar sensor and weaken them. In order to solve this problem, by depositing indium (In) on the surface of a non-metallic material that forms the CI mark, an ornament having a metallic luster and excellent radio wave transmission is realized (for example, Patent Document 1). See).

JP 2008-273216 A

  Since indium is an expensive rare metal, the use of indium for an ornament causes a high cost of the ornament. Further, indium has a silver-white metallic luster, but it is difficult to adjust the color tone to make it brighter or darker. For this reason, the ornament using indium has a monotonous color tone, and it is difficult to realize a desired design.

  In view of the above problems, an object of the present invention is to provide a vehicle member suitable for an ornament of an automobile.

An exemplary vehicle ornament according to one aspect of the present invention includes a translucent film that is radio wave permeable and contains no metal components, and a gray printed or painted film formed on the back side of the film. And, a light blocking film partially formed so as to draw a predetermined pattern on the front surface of the film, and a surface member integrally formed with the film to have a light transmitting property and cover the front surface of the film. The film is a film in which hundreds to thousands of nano-level polymer thin films are laminated with various layer thicknesses, and the predetermined pattern is drawn in the laminating direction of the surface member and the film. The position where the surface member, the film, and the gray printing film or the coating film are sequentially laminated, and in the laminating direction of the surface member and the film, the predetermined pattern is The positions other than the positions where the surface member, the light blocking film, the film, and the gray printing film or the coating film are sequentially laminated, and the film is aligned with the predetermined pattern. The embossed pattern formed by the above, the gray printing film or coating film reflects light that enters from the front surface of the film and transmits through to the back surface, and the film is the gray printing film or coating film There by reflecting the light the transmittance in Table side, a shall of Teisu more brilliant metallic luster as compared with the case where the gray print film or coating film is not formed. According to this, it is possible to realize a vehicle ornament excellent in design and radio wave transmission. In addition, since the film does not contain metal components, the radio wave transmission of vehicle ornaments can be further improved, or the cost of vehicle ornaments can be reduced because expensive rare metals such as indium do not have to be used. can do.

  Specifically, lightness and / or chroma are different between a portion where the light blocking film is formed and a portion where the light blocking film is not formed. According to this, the design of the vehicle ornament can be freely changed.

  Specifically, the light blocking film is a printed film or a coating film. According to this, the light blocking film can be easily formed.

Preferably, the film is only the portion that is not the light blocking layer is formed when viewed from the front side surface is intended to show a metallic color, the brightness of the print film or coating film before Symbol gray, its It has the metal color according to lightness. According to this, it is possible to realize a vehicle ornament excellent in design and radio wave transmission.

  Specifically, at least a part of the vehicular ornament is a member arranged in a transmission / reception radio wave range of the on-vehicle radar device. According to this, the vehicle ornament in which the radar sensor is mounted in the center of the front surface can be used as the ornament of the vehicle.

1 is a perspective view of a vehicle having an ornament made of a vehicle member according to an embodiment. Exploded perspective view of a vehicle member according to one embodiment. Sectional view of the vehicle member shown in FIG. Flowchart of a method for manufacturing a vehicle member according to one embodiment 4 is a schematic diagram illustrating each step of the flowchart of FIG. Figure following FIG. 5A

  Hereinafter, embodiments will be described in detail with reference to the drawings as appropriate. However, an unnecessary detailed description may be omitted. For example, a detailed description of a well-known item or a redundant description of substantially the same configuration may be omitted. This is to prevent the following description from being unnecessarily redundant and to facilitate understanding by those skilled in the art.

  The inventors provide the accompanying drawings and the following description so that those skilled in the art can fully understand the present invention, and they are intended to limit the subject matter described in the claims. is not. In addition, dimensions, thicknesses, detailed detailed shapes, and the like of each member illustrated in the drawings may be different from actual ones.

  FIG. 1 is a perspective view of a vehicle having an ornament made of a vehicle member according to one embodiment of the present invention. A front grill 101 is arranged on a front portion of the vehicle 100. The ornament 102 is arranged at the center in the width direction of the front grille 101, that is, at the center of the front side of the vehicle 100 in the vehicle width.

  The vehicle 100 includes a radar sensor (vehicle-mounted antenna) 103 for detecting an obstacle ahead of the vehicle such as a preceding vehicle. The radar sensor 103 irradiates the millimeter wave radar in front of the vehicle and receives a reflected wave from the preceding vehicle, thereby recognizing a speed difference from the preceding vehicle and an inter-vehicle distance.

  The radar sensor 103 is arranged at a position about ten and several centimeters behind the ornament 102. That is, the ornament 102 is arranged at a radio wave emission surface of the radar sensor 103 and at a position relatively close to the radar sensor 103. Therefore, most of radio waves radiated from the radar sensor 103 to the front of the vehicle and reflected waves from obstacles in front of the vehicle pass through the ornament 102. For this reason, the ornament 102 needs to be formed of a member having high radio wave transmittance so that the radio wave entering and radiating to the radar sensor 103 is not absorbed and diffused by the ornament 102 and weakened.

  The vehicle member according to the present embodiment is a member that has high radio wave transmission, has excellent design properties, and is suitable for use in vehicle exteriors such as ornaments that are easily visible. Hereinafter, the structure and the manufacturing method of the vehicle member according to the present embodiment will be described in detail.

≫Structure of vehicle components≫
First, the structure of the vehicle member according to the present embodiment will be described. FIG. 2 is an exploded perspective view of a vehicle member used for the ornament 102. FIG. 3 is a sectional view thereof. Note that, as described later, the vehicle member is formed by integrally forming the respective components in close contact with each other, but FIG. 3 illustrates the respective components separately for convenience.

The vehicle member 10 includes a surface member 11, a membrane 12, and a base member 13. The film 12 is sandwiched between the surface member 11 and the base member 13. The overall shape of the vehicle member 10 is arbitrary. For example, when the vehicle member 10 is used as the ornament 102 as shown in FIG. 1, the vehicle member 10 can have a substantially elliptical shape.

  The surface member 11 is a member that is exposed to the outside of the vehicle 100 and is provided to protect the front side surface of the membrane 12. The surface member 11 is made of a light-transmitting material so as not to impair the gloss of the film body 12, and has a smooth surface. As the surface member 11, for example, organic glass can be used. Among the organic glasses, polycarbonate (PC) is particularly excellent in transparency (high light transmittance), heat resistance, impact resistance and the like, and is suitable as a material for the surface member 11.

  The thickness of the surface member 11 is arbitrary. Further, the thickness of the surface member 11 may not be uniform. For example, when the vehicle member 10 is used for the ornament 102 as shown in FIG. 1, the surface member 11 may be formed into a substantially spherical shape such that the center portion of the surface member 11 is thickest and becomes thinner toward the edge. As described above, the surface member 11 may not only protect the film-shaped body 12 but also give it a three-dimensional shape (for example, a rounded shape) to have a design property.

  The film body 12 is made of a translucent material that has radio wave permeability and further reflects light in a complicated manner to give a special gloss and texture. As such a film-like body 12, for example, a film P! CASUS (registered trademark) can be used. The film is formed by laminating hundreds to thousands of nano-level polymer thin films in various layer thickness patterns, and exhibits a natural metallic gloss by reflecting incident light on the surface of each layer. Can be. Moreover, since the film does not contain a metal component, it has excellent radio wave transmission.

  The film-like body 12 is easily scratched on its surface, and is easily broken because its thickness is as thin as about 100 to 200 microns. Therefore, the film body 12 is not suitable for an exterior member that is exposed to the external environment. Therefore, as described above, the film 12 is covered with the surface member 11 to protect the film 12 from being exposed to the external environment.

  A gloss film 122 may be formed on the back surface of the film 12. The thickness of the gloss film 122 is arbitrary. The brightness of the glossy film 122 may be larger than 0% and smaller than 100%. That is, the glossy film 122 only needs to be glossy gray, and a color or pattern may be added as needed. By forming the glossy film 122 on the back side surface of the film-like body 12, light incident from the front side surface of the film-like body 12 and transmitted to the back side surface is reflected on the front side surface, and the glossy film of the film-like body 12 is formed. The portion where 122 is formed has a more vivid metallic luster.

  By changing the brightness gradation of the glossy film 122, the appearance of the film-like body 12 changes. For example, if the glossy film 122 is light gray, the film 12 emits a lighter metallic color. On the other hand, when the glossy film 122 is made dark gray, the film 12 emits a dark metallic color. Therefore, the brightness of the glossy film 122 may be appropriately determined according to a desired color tone for the film-like body 12.

  On the other hand, the light blocking film 123 may be partially formed so as to draw a predetermined pattern on the front surface of the film body 12. The thickness of the light shielding film 123 is arbitrary. The light shielding film 123 is a film that literally blocks light, and has an arbitrary color. For example, the light-blocking film 123 may be solid black, or may be partially changed in color tone, and may be further subjected to gradation. That is, the brightness and / or the saturation may be different between the portion where the light shielding film 123 is formed and the portion where the light blocking film 123 is not formed. Thereby, the contrast between the portion where the light shielding film 123 is formed and the portion where the light shielding film 123 is not formed becomes noticeable, and the pattern drawn by the light shielding film 123 can be made to stand out.

  By partially forming the light blocking film 123 on the front surface side of the film body 12, only the portion where the light blocking film 123 is not formed can emit a metal color. For example, by forming an inverted image of the CI mark on the front surface of the film body 12 with the light blocking film 123, it is possible to make it look as if the CI mark made of metal is attached. Conversely, by forming the CI mark on the front side surface of the film body 12 with the light blocking film 123, it can be made to look like a metal plate with the CI mark cut out.

  An embossed (embossed) pattern 124 may be formed on the front surface of the film 12 in accordance with the pattern drawn by the light blocking film 123. Thus, the design drawn by the light shielding film 123 can be three-dimensionally displayed, and the design can be further enhanced.

  When the embossed pattern 124 is formed on the front and side surfaces of the film 12, the same embossed pattern is formed on the surfaces of the surface member 11 and the base member 13 that are in contact with the film 12.

  Further, the pattern drawn by the light shielding film 123 and the embossed pattern 124 do not need to be matched. By forming different patterns for the light blocking film 123 and the emboss, respectively, the film-shaped body 12 exhibits a different design of impression.

The base member 13 is a member that supports the film-shaped body 12 from the back side. As described above, since the film-like body 12 is a thin film-like member, it is desirable that the film-like body 12 is sandwiched between the surface member 11 and the base member 13 for protection and reinforcement. The thickness of the base member 13 is arbitrary. Further, a projection, a boss, or the like can be provided on the back side surface of the base member 13. As the base member 13, for example, a resin can be used. Among the resins, ABS (Acrylonitrile-Butadiene-Styrene) resin and AES (Acrylonitrile-Ethylene-Styrene) resin are particularly excellent in thermoplasticity, rigidity, hardness and the like, and are suitable as the material of the base member 13.

製造 Method of manufacturing vehicle components 部 材
Next, a method for manufacturing the vehicle member according to the present embodiment will be described. FIG. 4 is a flowchart of a method for manufacturing the ornament 102 described above. 5A and 5B are schematic diagrams illustrating each step of the flowchart of FIG.

  First, a film (for example, P! CASUS manufactured by Toray Industries, Inc.) serving as a base of the film-like body 12 is cut into an appropriate size (step S1).

  Next, a gloss film 122 is formed on the back side of the film (step S2). For example, the glossy film 122 can be formed by printing or painting.

  Next, the light shielding film 123 is partially formed on the front surface of the film (Step S3). For example, the light blocking film 123 can be formed by printing or painting. However, printing or painting is performed by properly positioning the light blocking film 123 at a predetermined position on the front surface side of the film.

  Note that the order of step S2 and step S3 may be interchanged.

  Next, the film is embossed to form an embossed pattern 124 (step S4). For example, after the film is heated and softened, it is set in a mold, and the embossed pattern 124 is formed on the film surface by vacuum forming or pressure forming.

Thereafter, a trimming process for removing unnecessary portions is performed (step S5). Thereby, the film-like body 12 is completed.

  Next, the surface member 11 and the film-like body 12 are integrally formed (Step S6). For example, the film-shaped body 12 is set in an injection molding die, and the polycarbonate which is the base of the surface member 11 is poured and welded to the film-shaped body 12.

  Next, the integrated surface member 11, the film-like body 12, and the base member 13 are integrally formed (step S7). For example, the integrated surface member 11 and the film-shaped body 12 are set in an injection molding die, and AES resin or ABS resin which is a base of the base member 13 is poured thereinto and welded to the integrated surface member 11 and the film-shaped body 12. Let it. Thereby, the vehicle member 10 is completed.

  Finally, a hard coat is applied to the surface of the surface member 11 to reinforce the surface of the vehicle member 10 (Step S8).

  As described above, the embodiments have been described as examples of the technology according to the present invention. For that purpose, the accompanying drawings and the detailed description have been provided.

  Therefore, among the components described in the accompanying drawings and the detailed description, not only components that are essential for solving the problem, but also components that are not essential for solving the problem, in order to illustrate the above technology. May also be included. Therefore, it should not be immediately recognized that these non-essential components are essential based on the fact that the non-essential components are described in the accompanying drawings and the detailed description.

  Further, since the above-described embodiment is for exemplifying the technology of the present invention, various changes, replacements, additions, omissions, and the like can be made within the scope of the claims or the equivalents thereof.
