[Industrial applications]

 The present invention relates to an automobile door trim, and more particularly to an automobile door trim that can easily apply various varieties to a skin material.

[0002]

[Prior Art]

 An automobile door trim that is normally installed in an automobile door panel is constructed by covering the surface of a core material that has shape retention and rigidity for mounting on the vehicle body panel with a skin material through a pad material such as urethane foam. Has been done.

Recently, in order to increase the commercial value of a product, instead of a single resin sheet as a skin material, different materials such as a resin sheet and a cloth, or a resin sheet and a carpet are used. By using a composite skin material that is a combination of colors, the design is improved.

For example, as shown in FIGS. 10 to 12, the structure of an automobile door trim 1 is such that a skin material 3 made of a resin sheet or the like is attached to the surface of a core material 2 formed into a required shape by vacuum forming or the like. In addition, a decorative sheet 4 such as a cloth is attached to a part of the surface of the same by press-fitting or the like, and in order to add a variation to the appearance, a different texture or gloss from the skin material 3 is used. The skin material 5 is pressure-bonded to the surface of the skin material 3 by a pressure bonding die.

[0005]

[Problems to be solved by the device]

 As described above, in the conventional automobile door trim 1 in which two types of skin materials 3 and 5 having different appearances and the decorative sheet 4 are set on the surfaces thereof, the molding process of the core material 2, the vacuum molding process of the skin material 3, and the decoration process are performed. It has been pointed out that the number of steps is very large and the material cost is high, such as the step of crimping the sheet 4 and the step of crimping the second skin material 5, resulting in a significant cost up. ..

Further, as shown in FIG. 12, the skin material 5 is press-fitted and fixed together with the decorative sheet 4 in the wood-grooving groove portion 2 a formed in the core material 2. The appearance is likely to be deteriorated due to curling and shrinkage, which is a major cause of poor appearance.

The present invention has been made in view of such circumstances. For the purpose of the present invention, a skin material having a different appearance is set at separate parts on the surface of a product, and the skin material A decorative sheet such as a cloth is installed between the door trims to greatly reduce the number of manufacturing steps for automobile door trims with a wide variety of exterior appearances, and eliminate the wood-graining process for the surface material so that no cosmetic problems occur. The purpose is to provide the car door trim.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention covers the surface of the core material with a skin material and attaches a decorative sheet to a part of the outer surface of the core material, so that the product can be applied to a plurality of spaced locations on the product surface. In the door trim for automobiles in which the skin materials are exposed to give the appearance variation, the skin material is divided by a parting line, and when the skin material is in the original state, it has a different texture pattern or a glossy state due to the embossing process. It is set, and the parting line is covered with a decorative sheet.

[0009]

[Action]

 As is clear from the above configuration, the surface material is set to have a different embossed pattern and glossy state at the parting line as a result of the embossing process at the time of the raw material, so after covering the surface of the core material with the surface material, Since it is only necessary to press and fix the decorative sheet from the upper side so as to hide the parting line, it is not necessary to newly crimp another skin material from the upper side of the skin material as in the past, and the number of manufacturing steps is greatly simplified. it can.

[0010] Furthermore, after the decorative sheet is pressure-bonded, it is possible to eliminate the wood graining process of the skin material end portion that accompanies the newly installed skin material, so that the appearance defects such as shorts, shrinkages, and swelling that occur in the wood grain portion of the skin material can occur. Can be prevented.

【Example】

 Hereinafter, embodiments of a vehicle door trim according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a first embodiment of an automobile door trim according to the present invention, FIG. 2 is a cross-sectional view showing the structure of the automobile door trim, and FIG. 3 is a skin material used for the automobile door trim. Fig. 4 is a perspective view showing the state of the original fabric, Fig. 4 is an explanatory view showing the Chevrolol process applied to the same skin material, and Figs. 5 to 7 are each a sticking process and a pressure bonding process of the skin material and the decorative sheet. FIG.

8 and 9 show a second embodiment of an automobile door trim according to the present invention. FIG. 8 is a cross-sectional view showing the structure of an automobile door trim, and FIG. 9 is a skin material of this door trim. It is explanatory drawing which shows the state at the time of original fabric.

First, as shown in FIGS. 1 and 2, an automobile door trim 10 according to the present invention is formed into a desired shape, and has a core material 11 having shape retention and mounting rigidity to a vehicle body panel. It is composed of a skin material 12 attached to the front surface side of the core material 11, and a decorative sheet 13 such as a cloth pressed to a part of the front surface side of the skin material 12. The material 12 is set apart from each other like the skin materials 12a and 12b of the upper portion and the lower portion, respectively.

A feature of the present invention is that the door trims 10 for automobiles having different texture patterns and glossiness of the skin materials 12a and 12b to give a variation in appearance to enhance the commercial value can be easily manufactured. is there.

The core material 11 is obtained by extruding a polypropylene resin and a filler such as wood powder or talc at an appropriate mixing ratio and agitating the mixture, extruding it into a sheet, heating and softening the sheet, and then cold-forming the sheet into a desired shape. It is formed into a desired curved shape by a press die (not shown).

Next, a manufacturing process of the automobile door trim 10 will be described with reference to FIGS. 3 to 7 for reference.

First, as shown in FIG. 3, when the skin material 12 is in the original state, the upper-side skin material 12a and the lower-side skin material 12b are separated by a parting line 14, and different from each other. The embossed patterns A and B are applied.

That is, as shown in FIG. 4, the skin material 12 supplied from the original roll 20 is heated by the heater 21, and the embossing roll 22 causes the embossing A on one side with the parting line 14 as a boundary, and the other side. The grain B is formed on the side, cooled by the cooling drum 23, and wound on the winding roll 25 through the balancer 24. The skin material 12 shown in FIG. 3 is obtained by completing the series of roll processing.

Next, as shown in FIG. 5, the core material 11 having a predetermined shape is placed on the mold surface of the vacuum molding die 30, and the adhesive 31 is applied to the surface of the core material 11. It has been applied.

Further, above the skin material 12, the skin material 12 is heated and softened in a state of being cut to be slightly larger than the outer shape of the core material 11, and the outer peripheral edge thereof is held by a clamp device 32.

Then, by driving an elevating mechanism (not shown), the vacuum forming mold 30 rises, the core material 11 and the skin material 12 are brought into close contact with each other, and air between the two is vacuum suction holes formed in the core material 11. 11a and the vacuum suction hole 30a of the vacuum molding die 30 are aerated to the outside by a vacuum suction means (not shown), the skin material 12 is adhered faithfully along the surface shape of the core material 11, and both are integrated. To be done.

At this time, the parting line 14 between the upper-side skin material 12a and the lower-side skin material 12b is affected by the complicated surface shape of the core material 11 and is in a meandering state (see FIG. 6). As will be described later, since the decorative sheet 13 hides the parting line 14, there is no problem in terms of appearance.

After that, as shown in FIG. 7, the decorative sheet 13 is set on the pressure-bonding lower mold 40, and the semi-finished product including the core material 11 and the skin material 12 shown in FIG. Positioning is set.

Then, the adhesive 42 is applied to the surface side of the skin material 12 which is the adhesive surface of the decorative sheet 13, the upper die 41 for crimping is lowered, and the upper and lower die 40, 41 for crimping are clamped. The decorative sheet 13 is pressure-bonded to the surface side of the skin material 12 so as to cover the parting line 14.

As described above, the manufacturing process of the automobile door trim shown in FIG. 1 includes a molding process of the core material 11, an integration process of the core material 11 and the skin material 12, and a pressure bonding step of the decorative sheet 13. The conventional four steps can be shortened to three steps, and the number of steps can be shortened, resulting in a significant cost reduction.

Further, since the upper-side skin material 12a and the lower-side skin material 12b are formed as different texture patterns A and B by the texture-rolling process when the skin material 12 is in the original state, the lower surface skin material is different from the conventional one. It is possible to eliminate the crimping process of the side skin material, the graining process, etc., and in addition to shortening the number of processes, it is possible to effectively solve problems in appearance of the peripheral edge part.

In the above-described embodiment, different texture patterns are formed by the texture-rolling process when the skin material 12 is in the original state, but different gloss states may be set.

Next, FIGS. 8 and 9 show another embodiment of the present invention. In this embodiment, the basic idea is the same as the above-mentioned embodiment, but the form is different.

That is, the expansion rate of the upper-side skin material 12a is 20 to 30%, whereas the expansion rate of the lower-side skin material 12b is 5 to 10%. For this reason, for example, when it is desired to use the skin material 12 having the same grain pattern and to finish the upper skin material 12a and the lower skin material 12b to have the same appearance, the difference in the expansion rate results in There may be differences in appearance, and it may not be possible to provide products with a similar feeling.

In this embodiment, when the skin material 12 is unprocessed, the upper surface skin material 12a and the lower side skin material 12b are divided by the parting line 14 by a chevrolet process, and the expansion rate is large and the upper part is greatly stretched. The side surface material 12a is subjected to deep drawing, shrinkage, and other texture treatment, and the lower side surface material 12b, which has a relatively small expansion rate and is not greatly stretched, is given an ordinary texture pattern.

Then, when the surface material 12 is in the original state, the difference in the grain pattern may be set corresponding to the difference in the expansion rate between the upper side surface material 12 a and the lower side surface material 12 b.

By doing so, when the skin material 12 is integrally attached to the surface side of the core material 11 by vacuum forming or the like, the difference in the expansion rate between the upper skin material 12a and the lower skin material 12b is suppressed. It can be absorbed by the difference in the grain pattern provided on the skin material 12 in the state, and the door trim 10 after molding has the appearance of the upper side skin material 12a and the lower side skin material 12b despite the difference in the expansion rate. It will be almost the same.

As described above, in this embodiment, in order to make the upper-side skin material 12a and the lower-side skin material 12b to have substantially the same appearance, different texture processing is performed when the skin material 12 is in the original state. The present invention can also be used in such a case.

[0035]

[Effect of the device]

 As described above, the vehicle door trim according to the present invention has the following special effects.

(1) Since different texture patterns or glossy materials are used as the skin material, after sticking this skin material on the surface of the core material, a decorative sheet is attached so as to hide the parting line of the skin material. If so, the appearance of the skin material can be easily changed, and the appearance performance of the product can be remarkably enhanced with a simple structure.

(2) An automobile door trim is obtained by molding a core material, and then attaching a skin material and pressing a decorative sheet, rather than separately attaching resin sheets having different embossed patterns to the core material. This has the effect of significantly reducing the cost by reducing the number of steps.

(3) When the external appearance of the skin material differs depending on the surface shape of the product, when the skin material is in the original state and when the surface treatment is performed, a texture pattern or the like changes depending on the difference in the expansion rate of the skin material. If this is done, the effect is that even if the expansion rate of the skin material varies depending on the part, the appearance can be almost the same.
