Description

  The present invention relates to a panel structure including a panel body and a decorative panel provided on the panel body.

  In general, a decorative panel is used on a portion that can be seen on the outside of an electric product or the like in order to make the appearance look decorative (see, for example, Patent Document 1 and Patent Document 2). Also in a car audio system, conventionally, a resin or metal decorative panel is provided on a panel body on the front side of the system.

  FIG. 6 shows an example of a conventional panel structure in a car audio system. This panel structure includes a panel main body 61, two decorative panels 62 provided on the front side of the panel main body 61 on both sides of the panel main body 61, a knob 65 provided on the front surface of the panel structural body, and a decorative panel 62. The knob 64 is provided so as to protrude from the front surface.

  FIG. 7 is an assembly view showing how the panel structure is assembled. As shown in the figure, when the panel structure is assembled, the knob 64 is inserted from the back side of the panel main body 61 so that the knob 64 protrudes from the surface of the decorative panel 62, and the decorative panel 62 is attached to the panel main body 61. Is positioned and fixed.

  FIG. 8 is a cross-sectional view of the decorative panel 62 portion. The decorative panel 62 is made of resin and has a boss 62b. The decorative panel 62 is fixed to the panel body 61 by positioning the decorative panel 62 by inserting the boss 62b into the through-hole 61a of the panel body 61, and thermally welding the boss 62b protruding from the back side of the panel body 61 to the panel body 61. Is done.

  FIG. 9 is a cross-sectional view showing the same part as FIG. 8 when another decorative panel 92 is used instead of the decorative panel 62. The decorative panel 92 is formed by pressing a metal plate such as aluminum. The decorative panel 92 is fixed to the panel body 61 with a double-sided tape. About another point, it is the same as that of the case of the panel structure of FIGS.

  In this way, in the conventional panel structure, in order to differentiate the appearance according to the grade in the product lineup, a decorative panel made of resin or metal is selectively used depending on the grade of the product. Used for.

  However, according to the above-described prior art, as shown in FIGS. 8 and 9, the decorative panel 92 formed by pressing a metal plate has the same panel thickness as that of the decorative panel 62 made of resin. Since it cannot be controlled arbitrarily, the wall thickness becomes uniform. For this reason, there is a disadvantage in that the design of the panel structure is different between the case where the resin decorative panel 62 is used and the case where the metal decorative panel 92 is used.

  On the other hand, in order to unify the design to that of the resin decorative panel 62, it is also conceivable to use an aluminum die cast as the decorative panel 92. However, doing so is undesirable because it increases the weight of the product.

  In addition, the resin decorative panel 62 and the metal decorative panel 92 have different structures because the fixing method to the panel body 61 is different. Therefore, it is necessary to perform different designs for both decorative panels. In this case, a common panel main body 61 cannot be used for both decorative panels. That is, it is necessary to use a different panel body according to the material of the decorative panel. If it does so, the number of parts will increase and manufacturing cost will also increase.

  Further, when the resin decorative panel 62 or the metal decorative panel 92 is selectively used, if the common knob 64 is used, the two decorative panels have different thicknesses. The protrusion amount of the knob 64 is different. This adversely affects the appearance quality of the panel structure and the operability of the knob 64.

  An object of the present invention is to provide a more improved technique for mounting a decorative panel in a panel structure in view of the problems of the prior art.

  In order to achieve this object, a panel structure of the present invention is a panel structure including a panel main body and a decorative panel provided on the panel main body, and is interposed between the panel main body and the decorative panel. It has the adjustment member which adjusts and determines the position of the thickness direction.

  Here, as a panel structure, what is used for electronic devices, such as a car audio system, corresponds, for example. As the decorative panel, for example, a pressed metal plate is applicable. As an adjustment member, the thing made from resin corresponds, for example.

  In this configuration, since the position in the thickness direction of the decorative panel with respect to the panel body is adjusted and determined by the adjustment member, the panel body can be obtained by using an adjustment member having an appropriate thickness when manufacturing the panel structure. The position of the decorative panel in the thickness direction can be arbitrarily controlled. Therefore, for example, even when a thin decorative panel formed by sheet metal pressing is used, the same position of the decorative panel surface as when a thick resin decorative panel is used can be obtained.

  Thereby, irrespective of the thickness of the decorative panel to be used, it is possible to make the appearance uniform and to make the protrusion amount of the knob from the panel surface constant. Moreover, since a decorative panel can be attached to a panel main body via an adjustment member, the structure in the panel main body for attachment can also be unified.

  The panel structure according to the second invention is characterized in that, in the first invention, the decorative panel is formed by sheet metal pressing, and the adjustment member is made of resin.

  The panel structure according to a third aspect of the present invention is characterized in that, in the first or second aspect, the adjustment member is fixed to the panel body, and the decorative panel is fixed to the adjustment member.

  A panel structure according to a fourth invention is the panel structure according to any one of the first to third inventions, wherein the decorative panel and another decorative panel having a different thickness or shape are provided instead of the decorative panel. Regarding other decorative panels, a part or all of the shapes of the surfaces of both decorative panels are the same, and the thickness and shape of the adjusting member are determined so that the positions of the shapes are the same. .

  In the panel structure according to the fifth invention, in the fourth invention, based on the fact that part or all of the surface shape and the position thereof are the same, it is possible to share a predetermined part for both the decorative panels. It is characterized by becoming.

  The panel structure according to a sixth aspect of the present invention is characterized in that, in the fifth aspect, the component is an operation element protruding from the front surface of the decorative panel. For example, a knob, a slider, a button, or the like corresponds to the operation element.

  In the panel structure according to the seventh invention, in any one of the fourth to sixth inventions, the other decorative panel is directly fixed to the panel body without interposing the adjusting member. Features.

  The panel structure according to the eighth invention is the same as the seventh invention in that the adjustment member and the method of attaching the other decorative panel to the panel body are the same. It can be shared.

  ADVANTAGE OF THE INVENTION According to this invention, the thickness direction position of the decorative panel with respect to a panel main body can be arbitrarily controlled at the time of manufacture of a panel structure. Therefore, the product lineup from standard models to high-end models can be easily configured by unifying the appearance regardless of the thickness and shape of the decorative panel to be used and changing the texture by using different decorative panels of different materials. be able to. In addition, it is possible to share parts such as an operator regardless of the thickness and shape of the decorative panel to be used. Moreover, the structure in the panel main body for attachment of a decorative panel can be unified about the decorative panel from which thickness and shape differ, and a panel main body can be shared. Further, the shape of the decorative panel of the press-processed product can be arbitrarily designed by adapting the shape of the adjusting member to the shape of the decorative panel of the press-processed product.

  FIG. 1 is a perspective view showing a panel structure used in a car audio product according to an embodiment of the present invention, and FIG. 2 is an assembly view of the panel structure. The car audio products are available in standard specifications and in higher grades with higher functions, and the panel structures shown in FIGS. 1 and 2 are used for higher grade products. .

  As shown in FIG. 1, the panel structure includes a panel body 1, a decorative panel 2 provided on the panel body 1, and knobs 4 and 5 protruding from the surface of the panel structure. As shown in FIG. 2, between the panel main body 1 and the decorative panel 2, it has the resin-made spacer 3 which has adjusted and determined the position of the thickness direction of the decorative panel 2. As shown in FIG. The panel body 1, the decorative panel 2, and the spacer 3 are provided with through holes 1a, 2a, and 3a for passing the knob 4, respectively.

  In addition, instead of the decorative panel 2, a resin decorative panel having the same shape as the combination of the decorative panel 2 and the spacer 3 is used for a standard specification product. As shown in FIG. 8, the resin decorative panel is directly mounted on the panel main body without interposing a spacer.

  The decorative panel 2 is formed by pressing an aluminum plate. For this reason, the decorative panel 2 cannot be formed as thick as the resin decorative panel. Therefore, the height of the surface of the decorative panel 2 relative to the panel body 1 is adjusted by the spacer 3 so as to be the same as the height of the panel surface when a resin decorative panel is used.

  In this case, if the surface shapes of the decorative panel 2 and the resin decorative panel are the same, the heights of both decorative panels are the same overall. However, when the surface shapes of both decorative panels are only partially the same, the height of the same portion can be made the same.

  FIG. 3 is a cross-sectional view of the decorative panel 2 portion. As shown in the figure, the spacer 3 has a welding boss 3 b for fixing the spacer 3 to the panel body 1.

By doing so, the spacer 3 can be fixed to the panel body 1. The through-hole 1b is also used when a resin decorative panel having a welding boss similar to the boss 3b is directly fixed to the panel body 1. That is, the panel main body 1 can be used in common for the press-type decorative panel 2 and the resin-made decorative panel that are selectively used according to the product grade.

  As shown in FIG. 2, the decorative panel 2 is attached to the panel main body 1 by first fixing the spacer 3 to the panel main body 1 by the above-described thermal welding, and then mounting the decorative panel 2 on both sides of the spacer 3. This is done by fixing with tape. The knob 4 is attached by being inserted into the through holes 1 a to 3 a from the back side of the panel body 1. Accordingly, the height of the surface of the decorative panel 2 with respect to the panel body 1 is adjusted and determined by the spacer 3 so as to be the same as the height of the panel surface when the resin decorative panel is used. Become.

  According to the present embodiment, the thickness direction position of the decorative panel 2 is adjusted and determined by interposing the spacer 3 between the panel body 1 and the decorative panel 2. The panel structure can be manufactured by arbitrarily setting the position in the thickness direction of the decorative panel 2 with respect to the panel body 1. Therefore, when the surface shape of the decorative panel 2 and the surface shape of the resin decorative panel in the case of using a resin decorative panel instead are the same, part or all The panel structure can be manufactured so that the height of the surface shape is the same.

  Thereby, the case where the decorative panel 2 is used and the case where the resin decorative panel is used can unify the appearance design of the panel structure. Therefore, the decorative panel 2 made of aluminum and the decorative panel made of resin can be properly used according to the grade of the product. Therefore, it is possible to easily achieve a lineup of products with different grades.

  Further, as described above, by making the height of the surface shapes of part or all of the decorative panel 2 and the resin decorative panel the same, the protruding amount of the knob 4 from both decorative panels can be made the same. . Therefore, when both decorative panels are used, the knob 4 can be shared without hindrance.

  In addition, since the spacer 3 is made of resin and the decorative panel 2 is an aluminum pressed product, an aluminum die-cast decorative panel having the same shape as the combination of the spacer 3 and the decorative panel 2 is used instead. The weight of the product can be reduced as compared with the case of using it.

  Moreover, since the attachment method of the spacer 3 with respect to the panel main body 1 is the same as the case of the resin-made decorative panels, the panel main body 1 is shared by the case where the decorative panel 2 is used and the case where the resin-made decorative panel is used. be able to.

  FIG. 4 is a cross-sectional view showing a part of a panel structure used in a car audio product according to another embodiment of the present invention. FIG. 4 shows the same parts as in FIG. In this panel structure, a decorative panel 32 and a spacer 33 that differ only in shape from the decorative panel 2 and the spacer 3 in FIG. 3 are used. About another point, it is the same as that of the case of the form of FIGS. 1-3. This panel structure is also used for higher grade products.
