Description

  The present invention relates to a metallic decorative component for a vehicle and a manufacturing method thereof, and more particularly, an improved structure of a metallic decorative component for a vehicle in which a metal sheet is fixed to the surface of a resin base material, and the like. The present invention relates to an advantageous manufacturing method of a metallic decorative component for a vehicle having a particularly improved structure.

  2. Description of the Related Art Conventionally, as a type of vehicle component, there is a so-called vehicle metallic decorative component in which a metal-like decoration is applied to the surface of a base material (resin base material) made of a resin molded product. There are roughly two types of this metallic decorative component for vehicles. One is a metal thin film such as a coating film by metallic coating or a plating film by metal plating on the surface of the resin base material. Is a type that is decorated with a metallic tone (for example, Patent Document 1 below). Another is a type in which a thin metal sheet is fixed to the surface of a resin base material as a metallic decoration. In any type of these metallic decorative parts for a vehicle, it is possible to advantageously achieve both excellent formability and light weight and improved high-class feeling.

  By the way, in general, a vehicle component having a structure in which a plurality of members are assembled to each other has a higher-grade impression than a monotonous structure including a single member. Can be given.

  Therefore, even in the above-described metallic decoration parts for vehicles, there is a structure in which a plurality of independent metallic decoration parts are assembled integrally with each other in order to obtain a sufficient luxury feeling. . However, in such an integrally assembled product of a plurality of metal decoration parts, when vibration is applied thereto, abnormal noise such as rubbing noise due to contact between the metal decoration parts assembled to each other, etc. There was a risk of occurrence.

  In addition, (a) a metallic decorative component formed by dividing the surface of one resin base material into a plurality of regions and forming a plurality of different types of metal thin films in each of the plurality of regions, (A) Metal adjustment in which a single metal sheet in which a very narrow groove portion that divides it into a plurality of regions is formed on the design surface by press molding is fixed to the surface of a single resin substrate. There are also decorative parts. In other words, these metallic decorative parts (a) and (b) are actually composed of a single member (metallic decorative part), but have an appearance (separately composed of an assembly of multiple members). Design processing for obtaining (experience) is performed. In such a metallic decorative component, the problem of abnormal noise generated in a metallic decorative component in which a plurality of members are actually assembled can be advantageously solved.

  However, in the metallic decorative part (a), there is no clear cut-off between the adjacent metal thin films, and the boundary between the metal thin films is planar, so the adjacent metal thin films The boundary between them will be blurred. For this reason, it has been extremely difficult to express a different body sensation on the design surface that allows different metal thin film formation sites to be recognized as separate members.

  On the other hand, in the metallic decorative component (a), since the groove portion is formed as a three-dimensional parting, it is recognized that each design surface portion divided into a plurality of such groove portions is a separate member. It is easy to get a different body feel. However, since the groove portion is relatively shallow, depending on the viewing angle, the bottom portion of the groove portion may be visually observed due to light reflection, and in such a case, a separate feeling is lost. Therefore, even in a metallic decorative component having a design surface formed by the surface of a metal sheet having a groove, it is still difficult to stably express a different body sensation on the design surface.

Japanese Utility Model Publication No. 4-30082

  Here, the present invention has been made in the background as described above, and the problem to be solved is that the metal sheet having one surface as a design surface is fixed to the surface of the resin base material.

  Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings.

  First, in FIG.1 and FIG.2, the cover panel which is a part of the instrument panel of a motor vehicle as an embodiment of the metallic decoration component for a vehicle having a structure according to the present invention, The perspective form and the form in which the cross section is partially enlarged are shown. As is clear from these drawings, the cover panel 10 of the present embodiment is composed of a flat plate material having a long rectangular shape or a trapezoidal shape as a whole. And the resin base material 12 which comprises the back side part, and the metal sheet 14 which comprises the surface side part are mutually fixed and formed.

  More specifically, as shown in FIGS. 3 and 4, the resin base material 12 is composed of a flat plate having a predetermined thickness and having a shape corresponding to the cover panel 10 as a whole. A rectangular window portion 16 is formed at a substantially central portion of the resin base material 12. A rectangular annular fitting groove 18 is formed around the window 16 so as to extend in the circumferential direction of the window 16. The fitting groove 18 has a V-shaped vertical cross-sectional shape. In addition, the resin material which forms this resin base material 12 is not specifically limited, For example, ABS resin, AAS resin, AES resin, PC, PMMA, PET, PBT, etc. of resin-made interior parts for automobiles What is generally used as a forming material is used alone or in combination of two or more.

  On the other hand, as shown in FIGS. 5 and 6, the metal sheet 14 is formed of a thin flat plate-like press-molded product having a shape corresponding to the cover panel 10 as a whole, and has one surface in the thickness direction (FIG. 5). The upper surface) is the design surface 20. The material of the metal sheet 14 is not particularly limited, but here, an aluminum material excellent in formability and lightness is used.

  And in the both-sides edge part of the length direction of such a metal sheet 14, these both-sides edge part is bent at right angles to the opposite side to the design surface 20 side over the full width, 22 are formed respectively. In addition, a through hole 24 having a rectangular shape corresponding to the window portion 16 of the resin base material 12 is formed in a substantially central portion of the metal sheet 14. Further, a rectangular frame portion 26 formed by bending the opening peripheral edge portion of the through hole 24 to the side opposite to the design surface 20 side is provided at a site where the through hole 24 is formed. Thus, the inner peripheral surface of the through hole 24 is configured.

  Further, a parting portion forming groove 28 as a groove portion is formed around the through hole 24 in the central portion of the metal sheet 14 so as to extend in the circumferential direction of the window portion 16. The parting portion forming groove 28 has a V-shaped vertical cross-sectional shape.

  As described above, in the metal sheet 14, the parting surface forming groove 28 is formed on the design surface 20, so that the design surface 20 is a central design surface portion including a region located inside the parting portion forming groove 28. 20a and two regions of the outer peripheral design surface portion 20b, which are regions (including the surfaces of the two bent portions 22 and 22) located outside the parting portion forming groove 28. The width and depth of the parting portion forming groove 28 are not particularly limited. For example, the width is set to a sufficiently narrow width of about 0.5 to 1.0 mm, and the depth is , About 0.5 to 1.0 mm.

  Then, the central design surface portion 20a of the two areas of the design surface 20 divided by the parting portion forming groove 28, that is, the peripheral portion of the through hole 24 located inside the parting portion forming groove 28, A first printing layer 30 made of a transparent ink layer is formed on the surface of the frame portion 26 that forms the inner peripheral surface of the hole 24. Moreover, the 2nd printing layer 32 which consists of a transparent ink layer is formed in the outer peripheral side design surface part 20b. The first printed layer 30 is provided with a large number of small concave portions, and a texture pattern is formed by the large number of concave portions. The second printed layer 32 is provided with a large number of linear ridges having an extremely narrow width, and a hairline pattern is formed by the large number of linear ridges. In FIG. 6, it should be understood that a large number of concave portions and a large number of linear ridges formed in the first and second printed layers 30 and 32 are omitted.

  Further, a colored layer 34 is formed on the inner surfaces of the bottom portion and both side portions of the parting portion forming groove 28. The color of the colored layer 34 is a dark color having a lower brightness than the color of the design surface 20, unlike the color of the design surface 20, that is, the silver color of aluminum and having a metallic luster. And it does not have a metallic luster, for example, is black.

  Thus, in the metal sheet 14, the central design surface portion 20a located inside the parting portion forming groove 28 and the outer peripheral side design surface portion 20b located outside the parting portion forming groove 28 are those parts. In the first printed layer 30 and the second printed layer 32 respectively formed in the above, different patterns of a wrinkle pattern and a hairline pattern are given. As is clear from this, in the present embodiment, the decorative portion is configured by the respective formation sites of the first printed layer 30 and the second printed layer 32 on the design surface 20.

  And the center side design surface part 20a (1st printing layer 30 formation area) to which these wrinkle patterns were provided, and the outer peripheral side design surface part 20b (2nd printing layer 32 formation area) to which the hairline pattern was provided are clarified. A three-dimensional parting part (parting line) 36 to be distinguished is formed in the parting part forming groove 28. A black colored layer 34 is formed on the inner surface of the parting portion forming groove 28 that forms the parting part 36. Therefore, when the angle at which the design surface 20 is viewed is changed, light is reflected on the bottom of the parting portion forming groove 28 and the bottom is easily visually recognized from the outside. It is possible to avoid as much as possible from being damaged.

  As a result, the metal sheet 14 is a single sheet, but the central design surface portion 20a provided with the embossed pattern on the inner side of the parting portion forming groove 28 and the outer side of the parting portion forming groove 28. The outer peripheral design surface portion 20b provided with the hairline pattern is made up of separate members, and the viewer is given a recognition as if the members were assembled with each other. A different body sensation can be expressed on the design surface 20.

  1 and FIG. 2, the metal sheet 14 having such a structure is formed on the surface of the resin base 12 on the surface opposite to the design surface 20 (the resin base in FIGS. 1 and 2). The upper surface of the material 12 is overlaid. Further, under such a state, the through hole 24 of the metal sheet 14 and the window portion 16 of the resin base material 12 are positioned to correspond to each other, and the frame portion 26 of the metal sheet 14 is formed on the outer peripheral surface of the resin base material 12. The window 16 is overlaid on the inner peripheral surface. Furthermore, a ridge 35 provided on the back surface opposite to the design surface 20 of the metal sheet 14 corresponding to the parting portion forming groove 28 provided on the design surface 20 of the metal sheet 14 extends over the entire length thereof. The resin base material 12 is fitted in the fitting groove 18. Further, the bent portions 22, 22 provided at both end portions in the length direction of the metal sheet 14 are overlapped so as to be hooked to both end surfaces in the length direction of the resin base material 12.

  And the metal sheet 14 and the resin base material 12 which were piled up in that way are mutually adhere | attached by the adhesive bond layer 38 interposed between them. As a result, the cover panel 10 is formed in which the front side portion is made of the metal sheet 14 and the back side portion is made of the resin base material 12. In addition, the kind of adhesive agent which forms the adhesive bond layer 36 is not limited at all, The well-known adhesive agent which can adhere | attach a metal and resin firmly is selected suitably, and is used.

  Thus, the cover panel 10 is configured by an integrally joined product in which one metal sheet 14 is bonded to one resin base material 12, and the design surface 20 of the metal sheet 14 remains as it is. The design surface 20 of the cover panel 10 is used. Therefore, in such a cover panel 10, the above-described appearance characteristics of the metal sheet 14 are reflected as they are, and the central side around the through hole 24 and provided with a textured pattern is a single member. The site | part which has the design surface part 20a, and the site | part which has the outer peripheral side design surface part 20b to which the hairline pattern divided by the parting part 36 (parting part formation groove | channel 28) is provided consist of a separate member, respectively. A different sensation of giving such recognition to the viewer can be expressed on the design surface 20.

  And here, even if the colored layer 34 is formed on the bottom inner surface and the both side inner surfaces of the parting portion forming groove 28 and the angle at which the design surface 20 is viewed is variously changed, the parting portion forming groove 28 is formed. The bottom of this is not easily visible from the outside. Thereby, in the design surface 20, the separate body sensation for recognizing the central side design surface portion 20a to which the embossed pattern is imparted and the outer peripheral side design surface portion 20b to which the hairline pattern is imparted as separate from each other is more effective. It can be expressed expressly.

  By the way, when manufacturing such a cover panel 10, the operation | work is advanced according to the following procedures, for example.

  That is, first, as shown in FIG. 7, a thin aluminum plate 40 is used as a raw material, and screen printing using black ink is performed on a substantially central portion of the surface of the aluminum plate 40 to narrow the surface. A linear colored layer 34 having a width is formed. The colored layer 34 is formed so as to draw a rectangular line. As a result, the surface of the aluminum flat plate 40 is divided into two regions, a portion inside the colored layer 34 and a portion outside the colored layer 34. In addition, although the metal sheet 14 is formed from the aluminum flat plate 40 by the process described later, the design surface 20 of the metal sheet 14 is formed on the surface that is the formation surface of the colored layer 34 of the aluminum flat plate 40. .

  Next, screen printing using a transparent ink is performed on a portion outside the colored layer 34 on the surface of the aluminum flat plate 40, so that the second printed layer 32 has a substantially rectangular shape that surrounds the colored layer 34. A shape or a trapezoidal shape is formed. The second printed layer 32 has a large number of linear ridges having an extremely narrow width, and a hairline pattern is drawn by the large number of linear ridges.

  Thereafter, screen printing using a transparent ink is performed on the portion inside the colored layer 34 on the surface of the aluminum flat plate 40 so that the overall shape of the first printed layer 30 becomes a rectangular frame shape. To form. The first printed layer 30 has a large number of small concave portions, and a texture pattern is drawn in the large number of concave portions. In addition, the formation order of the colored layer 34, the 2nd printing layer 32, and the 1st printing layer 30 is not limited at all to the above-mentioned order, and each layer 34, 32, 30 can be performed in arbitrary orders. . If possible, at least two of these layers 34, 32, and 30 may be formed simultaneously.

  Then, the punching process which punches the aluminum flat plate 40 along the outer peripheral edge part of the formation part of the 2nd printing layer 32 using a press apparatus (not shown) is performed. As a result, as shown in FIG. 8, the first printed layer 30 and the colored layer 34 are printed and formed on the substantially central portion of the surface, and the second outer peripheral portion around the substantially central portion is formed on the entire surface. A blank 42 on which the printing layer 32 is formed is obtained. Further, at the same time as or after the formation of the blank 42 by such a punching process, a blanking process for punching a portion inside the first printing layer 30 where no printing layer is formed is performed, so that a substantially center of the blank 42 is formed. A rectangular through hole 44 surrounded by the first printing layer 30 is formed in the part.

  Next, using a press device (not shown), the both sides of the length direction of the blank 42 are bent at a right angle to the side opposite to the design surface 20, Bending portions 22 and 22 are formed (see FIG. 5). At the same time or thereafter, the blank 42 is bent by bending the inner peripheral side portion of the formation portion of the first printed layer 30 at right angles to the opposite side of the design surface 20 over the entire circumference. A frame portion 26 is formed at a substantially central portion of the, and a through hole 24 having the frame portion 26 as an inner peripheral surface is formed.

  Further, at the same time as the formation of the bent portion 22 and the frame portion 26, or before and after the formation, the forming portion of the linear colored layer 34 that draws the rectangle of the blank 42 is formed by press molding using a pressing device (not shown). Bending is performed so that it is recessed in a V shape over the entire circumference. Thus, a parting portion forming groove 28 having a rectangular ring shape extending along the formation portion of the colored layer 34 and having a V-shaped cross section is formed on the design surface 20 of the blank 42. In forming the parting portion forming groove 28, the parting portion forming groove 28 is formed by denting the colored layer 34 forming portion so that the center in the width direction of the linear colored layer 34 is the deepest part. The colored layer 34 is formed at least over the entire inner surface of the bottom.

  Thus, the metal sheet 14 having the structure shown in FIGS. 5 and 6 is obtained by the press-formed product of the aluminum flat plate 40. That is, the design surface 20 is divided by the parting portion forming groove 28 into two regions, that is, a central design surface portion 20a which is an inner portion thereof and an outer peripheral design surface portion 20b which is an outer portion thereof. Since the embossed pattern and the hairline pattern are respectively given to the portions 20a and 20b, and the metal sheet 14 in which the colored layer 34 is formed on the inner surface of the bottom portion and the inner surfaces of both side portions of the parting portion forming groove 28 is obtained. is there.

  Moreover, while obtaining such a metal sheet 14, the resin base material 12 which has a structure as shown by FIG.3 and FIG.4 is formed, for example by implementing injection molding.

  Thereafter, using the metal sheet 14 and the resin base material 12, as described above, the metal sheet 14 is superposed on the surface of the resin base material 12 via the adhesive layer 38 and bonded. Thus, the target cover panel 10 is obtained.

  As described above, in the cover panel 10 of the present embodiment, the parting portion forming groove 28 is formed in spite of being an integrally joined product in which one metal sheet 14 is bonded to one resin base material 12. In addition to the embossed central design surface portion 20a and the outer peripheral design surface portion 20b being provided with different patterns of the wrinkle pattern and the hairline pattern, respectively, the bottom of the parting portion forming groove 28 A black colored layer 34 is formed over the entire length of the parting portion forming groove 28 on the inner surface and the inner surfaces of both side portions. Then, in the design surface 20, a separate body sensation that allows the central design surface portion 20 a provided with the embossed pattern and the outer peripheral design surface portion 20 b provided with the hairline pattern to be recognized as separate from each other, It can be expressed more effectively.

  Therefore, in the cover panel 10 of the present embodiment as described above, the high-quality feeling obtained in the assembly of a plurality of members can be obtained extremely effectively and stably even though it is a single member. It becomes.

  Moreover, in the cover panel 10 of this embodiment, the parting part formation groove | channel 28 has V-shaped cross-sectional shape. Therefore, the bottom portion of the narrow part forming groove 28 is further narrowed. Therefore, the bottom of such a parting portion forming groove 28 can be made more difficult to see from the outside than the bottom of the groove having a rectangular cross section, for example. As a result, the separate feeling of the central design surface portion 20a and the outer peripheral design surface portion 20b divided by the parting portion forming groove 28 is expressed more effectively, and thus a further high-class feeling. Improvements can be made advantageously.

  In manufacturing the cover panel 10, the colored layer 34 is formed on the design surface 20 of the aluminum flat plate 40, and then the portion where the colored layer 34 is formed in the blank 42 punched out from the aluminum flat plate 40 is press-bended. Thus, the parting portion forming groove 28 having the colored layer 34 is formed at least on the inner surface of the bottom portion. Therefore, for example, compared with the case where the colored layer 34 is formed at the bottom of the parting portion forming groove 28 after the parting portion forming groove 28 is formed by press bending to the blank 42, the colored layer 34 is formed. It can be implemented very easily. Therefore, according to this embodiment, the cover panel 10 that exhibits the above-described excellent characteristics can be more easily formed with excellent workability.

  The specific configuration of the present invention has been described in detail above. However, this is merely an example, and the present invention is not limited by the above description.

  For example, the colored layer 34 is not limited to black at all, and if the color is darker than the design surface 20 of the metal sheet 14, that is, a color with low brightness, whether the color is the same color as the design surface 20 or a different color. Any color is acceptable. Among them, a matte color or the like having low light reflectivity can be suitably employed.

  Moreover, the colored layer 34 can also be comprised by the coating layer formed by various coating methods other than the printing layer (ink layer) formed by printing methods other than the illustrated screen printing.

  The cross-sectional shape of the parting part forming groove 28 as a groove part formed on the design surface 20 of the metal sheet 14 is not necessarily V-shaped. The cross-sectional shape of the parting part forming groove 28 is rectangular or U Various shapes such as a letter shape can be employed.

  Further, the overall shape of the parting portion forming groove 28 serving as the groove is not limited to the illustrated rectangular shape, and may be a rectangular shape or a shape that divides the design surface 20 of the metal sheet 14 into a plurality of regions. In addition to a closed shape such as a circular shape, a linear shape, a curved shape, or the like can be appropriately employed.

  Furthermore, in the said embodiment, although the metal sheet 14 was adhere | attached on the surface of the resin base material 12, and the cover panel 10 as a vehicle metallic decoration part was formed, a resin sheet is attached to the surface of the resin base material. You may adhere | attach and may comprise the metallic decoration part for vehicles. Of course, even in this case, a groove portion that divides the design surface into a plurality of regions is formed on the design surface of the resin sheet, and a darker colored layer than the design surface of the resin sheet has at least the groove portion. It will be formed over the entire length of the bottom.

  In addition, patterns and patterns formed on the design surface of metal sheets and resin sheets are not limited to the embossed patterns and hairline patterns shown in the examples, but also from geometric patterns and amorphous shapes, various characters and symbols, etc. Various known patterns and patterns such as patterns and patterns can be adopted. The geometric pattern includes, for example, one of the same size of a circle, an ellipse, an ellipse, a polygon, and a line segment (including straight lines, bent lines, curved lines, wavy lines, etc.) Patterns formed with different sizes and patterns formed by combining two or more of them are included. In addition, in geometric patterns formed including circles, ellipses, ellipses, and polygons, only the outlines of those shapes are composed of concave grooves or ridges, The whole or a part thereof is also recessed or protruded. In addition, the pattern and pattern formed in the design surface of such a metal sheet or a resin sheet are not essential.

  Furthermore, when the design surface of the metal sheet or the resin sheet is divided into three or more regions at the groove portion, a pattern or a pattern is formed in at least one of the three or more regions.
