Description

The present invention relates to an interior component in which a display body composed of light figures and characters is watermarked on the surface of the epidermis as needed.

For example, in Patent Document 1, in an interior part such as a dashboard of a vehicle, a base material, a display unit fixed to the rear surface of the base material, and a position further rearward from the display unit by a predetermined dimension are arranged. A configuration including a design panel and a light unit and a light guide body arranged above and below the display unit is described.

The design panel is made of a light-transmitting dark acrylic resin. The light emitted from the light unit and the light guide body is reflected by the reflecting surface and heads toward the display unit, so that the pattern of the display unit appears on the front side of the design panel. On the other hand, when the light is not emitted from the light unit, the presence of the light unit and the display unit arranged on the back side of the design panel becomes difficult to see.

Japanese Patent No. 6350332 (Japanese Patent Laid-Open No. 2016-150650)

In Patent Document 1, it is pointed out that the design of the design panel is restricted because it is essential to darken the design panel.

In view of such circumstances, the present invention is an interior component in which a display body composed of light figures and characters is watermarked on the surface of the skin as needed, without being restricted by the design of the skin. The purpose is to prevent the back side of the epidermis from being seen through when the watermark is not displayed.

The interior parts according to the present invention include a translucent skin manufactured by slush molding, a base material provided on the back surface of the skin and provided with an opening at a predetermined position, and the back side of the base material. It is characterized in that it is provided with a light unit which is arranged in an opening and emits light toward the epidermis.

According to this configuration, when light is emitted from the light portion, the light is irradiated to the back surface of the epidermis through the opening of the base material. As a result, the light is transmitted to the surface side of the skin, so that a display body composed of light figures and characters can be watermarked on the surface of the skin of the interior component.

On the other hand, when the light portion does not emit light, the light portion arranged on the back side of the epidermis can be seen through from the surface side of the epidermis to the extent that sunlight or an interior light hits the surface of the epidermis. Since there is no such thing, the design of the surface of the epidermis does not change, such as the entire surface of the epidermis becoming the color of the material. As a result, unlike the design panel of Patent Document 1, it is not necessary to darken the skin, so that the design of the interior parts according to the present invention is not restricted, and the degree of freedom in design can be improved.

According to the present invention, it is possible to provide an interior component in which the back side of the skin cannot be seen through when the watermark is not displayed, without being restricted by the design of the skin.

It is a figure which shows the manufacturing process of the interior part of FIG.

Hereinafter, the best embodiment for carrying out the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 show an embodiment of the present invention. In the figure, 1 indicates the entire interior parts.

The interior component 1 of this embodiment is an instrument panel or the like of a vehicle. Specifically, the interior component 1 includes a skin 2, a base material 3, and a lighting unit 4.

The skin 2 is made of thermoplastic urethane (TPU) uniformly and thinly formed by slush molding, and has translucency.

Although the skin 2 has translucency, the back side of the skin 2 cannot be seen through to the extent that sunlight, interior lights, etc. are exposed from the front side.

Specifically, the skin 2 is obtained by mixing a predetermined amount of a desired pigment with a powdery (fine particle) resin made of, for example, thermoplastic urethane, and distributing it in an appropriate molding die at the time of the slush molding. Manufactured in a uniform and predetermined film thickness. The skin 2 obtained by adding a pigment to a powdery TPU resin and then slush molding can have a coarse and dense pigment concentration. When a strong light source is applied to the epidermis 2, light leaks from a portion where the pigment concentration is locally coarse and transmits light.

The base material 3 is provided on the back surface of the skin 2 via a filler 5, and an opening 3a is provided at a predetermined position thereof, and the light portion 4 is fixed around the opening 3a. A receiving frame portion 3b is provided.

The light portion 4 is arranged in the opening 3a on the back side of the base material 3, and emits light toward the skin 2.

The light unit 4 is, for example, a display for displaying a display body 6 (see, for example, FIG. 2) such as various light figures and characters, and the display screen is arranged so as to be exposed to the opening 3a. ..

Then, the mounting piece 4a of the exterior portion of the lighting portion 4 is fixed to the receiving frame portion 3b of the base material 3 with a fastening member 7 such as a screw.

As a manufacturing procedure for such an interior component 1, for example, as shown in FIG. 4A, a front side of a base material 3 molded into a predetermined shape is designated on the back side of a skin 2 molded into a predetermined shape. It is fitted with a gap between them, and the filler 5 is filled in the gap as shown in FIG. 4 (b). After that, as shown in FIG. 4 (c), the light portion 4 is aligned with the receiving frame portion 3b of the base material 3, and the light portion 4 is applied and fastened with the fastening member 7.

Next, the display operation by the interior component 1 will be described.

First, when a switch (not shown) is turned on, the light unit 4 is driven to display a display body 6 composed of a color image of light as shown in FIG. 2, for example, on the display unit of the light unit 4. Therefore, the light constituting the display body 6 is emitted from the opening 3a of the base material 3 from the back side to the front side of the skin 2, so that the display body 6 is transmitted to the front side of the skin 2 and displayed as a watermark. Will be done.

On the other hand, when the switch is turned off, the display body 6 disappears from the display unit of the light unit 4, and the light directed to the skin 2 disappears, so that the entire surface of the skin 2 becomes the color of the material. .. In this way, when the light unit 4 is hidden, the light unit 4 arranged on the back side thereof cannot be seen through the front side of the skin 2.

According to the embodiment to which the present invention is applied as described above, when the light is emitted from the light unit 4, the light is irradiated to the back surface of the skin 2 through the opening of the base material 3. As a result, the light is transmitted to the surface side of the skin 2, so that a display body composed of light figures and characters can be watermarked on the surface of the skin 2 of the interior component 1.

On the other hand, when the light unit 4 does not emit light, the light unit 4 arranged on the back side of the skin 2 can be seen through from the surface side of the skin 2 to the extent that the surface of the skin 2 is exposed to sunlight or indoor lights. Since there is no such thing, the design of the surface of the skin 2 does not change, such as the entire surface of the skin 2 becoming the color of the material. As a result, it is not necessary to darken the skin 2 as in the design panel of Patent Document 1, so that the design of the interior component 1 according to the present invention is not restricted, and the degree of freedom in design can be improved. ..

The present invention is not limited to the above embodiment, and can be appropriately modified within the scope of claims and within the scope equivalent to the scope.

(1) For example, FIGS. 5 and 6 show other embodiments of the present invention. In this embodiment, the transmissive film 8 is adhered to a predetermined region of the skin 2 shown in FIG. 1, and the light portion 4 is used as a light source that emits light having an appropriate wavelength (color).

The transmissive film 8 is provided with a transmissive pattern (not shown) for creating a display body (not shown) composed of light figures and characters. This transmission pattern is formed by a combination of a portion that allows light to pass through and a portion that does not allow light to pass through.

Other configurations are basically the same as those of the embodiment shown in FIG. Also in this embodiment, the same actions and effects as those in the above embodiment can be obtained.

Specifically, in this embodiment, first, when a switch (not shown) is turned on, the light unit 4 is driven to emit light from the light unit 4, and this light is emitted. Since the light is transmitted to the surface side of the skin 2 through the transmission pattern of the transmission film 8, a display body (not shown) made of light corresponding to the transmission pattern is displayed as a watermark on the surface of the skin 2 of the interior component 1. Will be done.

On the other hand, when the switch is turned off, the light from the light unit 4 toward the skin 2 disappears. Therefore, the light unit 4 arranged on the back side of the skin 2 to the extent that the surface of the skin 2 is exposed to sunlight or interior light. However, the design of the surface of the skin 2 does not change, such as the fact that the skin cannot be seen through the front side of the skin 2. In this way, when the light unit 4 is hidden, the entire surface of the skin 2 becomes the color of the material.

(2) For example, FIGS. 7 and 8 show other embodiments of the present invention. In this embodiment, in order to create a display body (not shown) composed of light figures and characters by using a laser processing machine 10 (see FIG. 8A) in a predetermined display area 9 of the skin 2 shown in FIG. The transmission pattern (not shown) is formed by, for example, printing, and the light unit 4 is used as a light source that emits light having an appropriate wavelength (color).

As shown in FIG. 8 (b), for example, the base material 3 is attached to the epidermis 2 having the transmission pattern formed in this way so as to be fitted via the filler 5 (see FIG. 7).

The transmission pattern is formed by a combination of a portion that allows light to pass through (for example, a non-baked portion) and a portion that does not allow light to pass through (for example, a baked portion).

Other configurations are basically the same as those of the embodiments shown in FIGS. 5 and 6. Also in this embodiment, the same actions and effects as those in the above embodiment can be obtained.

Specifically, in this embodiment, first, when a switch (not shown) is turned on, the light unit 4 is driven to emit light from the light unit 4, and this light is emitted. Since it is transmitted to the surface side of the skin 2 through the transmission pattern of the skin 2, a display body (not shown) composed of light corresponding to the transmission pattern in the display area 9 on the surface of the skin 2 of the interior component 1. Will be displayed as a watermark.

On the other hand, when the switch is turned off, the light from the light unit 4 toward the skin 2 disappears. Therefore, the light unit 4 arranged on the back side of the skin 2 to the extent that the surface of the skin 2 is exposed to sunlight or interior light. However, the design of the surface of the skin 2 does not change, such as the fact that the skin cannot be seen through the front side of the skin 2. In this way, when the light unit 4 is hidden, the entire surface of the skin 2 becomes the color of the material.

(3) In the above embodiment, an example in which the filler 5 is interposed between the skin 2 and the base material 3 is given, but the present invention is not limited to this, and for example, the filler 5 is used. The lost configuration can also be an embodiment of the present invention.

(4) In each of the above embodiments, an example is given in which the interior component according to the present invention is an instrument panel or the like of a vehicle, but the present invention is not limited to this, for example, a door trim of a vehicle or the like. It can be applied as an interior part placed in various places in a vehicle.

INDUSTRIAL APPLICABILITY The present invention can be suitably used for interior parts in which light figures and characters can be watermarked on the surface of the epidermis as needed.
