Description

[Detailed explanation of the invention] (Field of industrial application) This invention relates to the improvement of automobile instrument decorative panels, and more specifically, the surface of the instrument decorative panel is covered with a natural veneer. , which brings a natural texture and deep taste, and at the same time provides a good feel to the instrument decorative panel.

(Prior art) The conventional instrument decorative panel was
On the other hand, we have improved functionality to accommodate instruments and make it easier to monitor and operate them, and they are located in the area that attracts the most attention, such as the front of the driver's seat, and the space occupied by these instruments has also been improved. Improvements have been made not only in terms of size, but also in terms of decoration.

Additionally, instrument decorative panels are required to have a structure and material characteristics that can withstand strong shocks or vibrations, and materials that can follow the temperature changes in local areas.

As a result, instrument decorative panels are made of composite materials such as metal panels, resin panels, or decorative sheets, and are configured to meet the respective requirements.

(Problems to be solved by the present invention) However, the surface of conventional instrument decorative panels is made of either metal or resin material, and their decorative functions tend to be uniform and insufficient. Although it has a functional beauty, it lacks originality.

In addition, the water absorption rate of either metal or resin materials is extremely low, and condensation or sweating tends to occur on the panel surface, and this condensation water can cause damage to the equipment stored in the instrument, or It was believed that this caused a significant loss of comfort in the interior of the car.

In addition, it naturally felt cold and dry to the touch in the winter, and tended to become sticky in the summer, making it unsuitable as a material for instrument decorative panels, which are often touched during driving operations. .

In order to avoid such inconveniences, some instrument decorative panels are made by printing wood grain on the surface of the resin panel, or by overlapping the prints to form a surface film. An attempt is made to exude decorative beauty.

However, in this cosmetic method, the resin molded product can be identified at a glance, and since the decorative surface is extremely thin, the cosmetic is easily damaged by scratches.

Further, although metal panels can produce a unique metallic color, they have poor moldability and are often unsuitable for integral molding of instrument decorative panels having unique curved shapes.

(Specific means for solving the problems) The present invention eliminates the inconveniences of the conventional instrument decorative panels, has rich decorative functions, has a good feel, and does not easily cause dew condensation or sweating. It provides panels.

Therefore, in the present invention, the instrument panel is made of a thermoplastic resin film with a thickness of 0.1 to 0.8 mm containing cellulose-based fine powder aggregate.
A decorative sheet made by laminating and bonding decorative veneers with a thickness of ~0.3 mm is pasted onto the panel with the resin film side of the decorative sheet facing the panel surface, and the decorative sheet and the panel are bonded together. The decorative sheet and panel were constructed as one unit with a foam cushioning material loaded between them.

(Embodiment) A typical embodiment of the present invention will be described below with reference to the accompanying drawings. First, the instrument decorative panel A that constitutes the front part of the driver's seat of a car is molded into an appropriate shape depending on the car type and other factors, and is mainly prepared as a resin molded product by injection molding or vacuum molding, or a metal panel material by press molding. be done. This instrument decorative panel A has mounting holes for various instruments such as speedometer, fuel gauge, water temperature gauge, etc., storage and mounting holes for warning lights such as brake warning light, oil pressure warning light, etc., and various mounting holes for various instruments such as drive fuel monitor. Monitor unit mounting hole, clock or radio,
It has mounting holes for a tuner, a cassette stereo deck, an air conditioner, etc., and a steering mounting part, a console box mounting part, etc. are suitably cut out.

A decorative sheet B is attached to such an instrument decorative panel A, and this decorative sheet B has the following configuration.

First, thoroughly dry the wood powder, etc., and
A vinyl chloride resin material is mixed with aggregate crushed into a fine powder of mesh size, and the mixture is rolled with a calendar roll to prepare a film 1 having a thickness of 0.1 to 0.8 mm. This film 1 has aggregate exposed on the surface of the film and is extremely thin, so it has sufficient air permeability and moisture permeability.

When the film 1 is roll-formed, a reinforcing material 2 such as cloth or paper is attached to the film 1 and pressed against the film 1, so that the film 1 and the material 2 are welded together. The fabric 2 has the purpose of reinforcing the film 1, inhibiting expansion and contraction of the film 1, and increasing adhesive strength with the panel.

Next, a veneer 3 having a thickness of 0.1 to 0.3 mm is pasted onto the other side of the film 1 to form a decorative sheet B.

This decorative sheet B may be left as it is, or may be subjected to a curing treatment by reheating, or may be rolled again to be bent and stretched to remove residual internal stress in the sheet.

The decorative sheet B constructed in this manner is pasted onto the required locations of the instrument decorative panel A with the surface of the veneer 3 facing up, and the decorative sheet B
A foam cushioning material 4 is loaded between the fabric 2 and panel A. This foamed cushioning material 4 is typically made by injecting and foaming a foamed urethane resin liquid, for example.
As a result, the panel A and the sheet B are bonded together through the cushioning material 4 when the foaming cushioning material 4 is foamed. Incidentally, a urethane foam material or the like may be prepared in advance, and the sheet B may be pasted and bonded to the surface of the panel A while interposing this material.

Incidentally, in the construction of the decorative sheet B described above, the lamination and attachment of the reinforcing fabric 2 made of cloth, paper, or cloth and paper may be omitted, and the surface of the film 1 may be subjected to a sanding treatment instead. Furthermore, in order to ensure that the veneer 3 is attached securely, the veneer 3 may be attached after sanding the surface of the film 1.

(Effects) The instrument decorative panel according to the present invention has the unique structure described above, and the panel surface is covered with a natural veneer 3, which provides a rich decorative function and has a natural feel. Since it is the same as wood, it is soft, has appropriate contact resistance and hygroscopicity, and has the advantage of not having a sweaty or sticky feeling. In addition, a comfortable living space is provided without condensation or sweating, and wear and tear on equipment is prevented. Furthermore, since the veneer 3 is protected by the cushioning material 4 and the film 1, it will not be torn or torn. Furthermore, since expansion and contraction of the veneer 3 is suppressed by the film 1 containing a special aggregate, the cushioning material 4, and the reinforcing fabric 2, peeling, tearing, or wrinkling due to expansion and contraction will not occur.

Also, due to the presence of the film 1 and the cushioning material 4, the veneer 3 can easily stretch or contract along the surface of the panel A, and adhere to the panel A, so that it will not tear or crack even at the bent portions. do not have.

Furthermore, the veneer 3 is not directly affected by the expansion and contraction of the panel A due to the interposition of the film 1 and the cushioning material 4, so that the veneer 3 will not be cracked, torn, or wrinkled due to the expansion and contraction of the panel A. There's nothing to do.

Further, the veneer 3 has the advantage that it can be firmly and reliably attached to the panel A by the interposition of the film 1 and the cushioning material 4.
