《Embodiment》
An instrument panel 1 shown in FIG. 1 is a panel including an instrument panel on which various devices such as an engine tachometer and a speedometer are mounted, and is installed at the front of a vehicle interior. The instrument panel 1 is supported by an instrument panel reinforcement (not shown) that extends in the vehicle width direction and is attached to the vehicle body.

One side of the instrument panel 1 in the left-right direction (the right side portion not shown in FIG. 1) corresponds to the driver's seat, and the other side (the left side portion illustrated in FIG. 1) corresponds to the passenger seat. A glove box 3 is attached to a lower position of a portion of the instrument panel 1 corresponding to a passenger seat so as to be openable and closable. A panel mounting portion 5 is provided above the glove box 3 of the instrument panel 1.

The panel mounting portion 5 is formed in a horizontally elongated concave shape extending in the width direction of the vehicle. The display panel 10 is fitted into the panel mounting portion 5 and mounted thereon. The display panel 10 closes the opening of the panel mounting portion 5 and is fixed to the instrument panel body. The display panel 10 is used as an interior material for a vehicle. The display panel 10 is formed into a horizontally long substantially rectangular shape when viewed from the front. The display panel 10 has a display window 12 that transparently displays an image.

- Composition of vehicle interior parts -
As shown in FIG. 2, the display panel 10 constitutes a vehicle interior component 7. As shown in FIG. The vehicle interior component 7 includes a display device 50 in addition to the display panel 10. The display panel 10 includes a base material 14 and a skin material 20. That is, the vehicle interior component 7 includes a base material 14, a skin material 20, and a display device 50.

The base material 14 is a plate-like resin material that serves as the base of the display panel 10. An opening 16 is formed in a portion of the base material 14 corresponding to the display window 12. This opening 16 has a shape corresponding to the outer shape of the display device 50. A plurality of bosses 18 (only two are shown in FIG. 2) are integrally formed around the opening 16 on the back surface of the base material 14.

The base material 14 is molded by injection molding or the like. The base material 14 is made of a synthetic resin that has light blocking properties. Examples of the material for the base material 14 include polypropylene (PP), polyethylene terephthalate (PET), polyester resin, and acrylonitrile butadiene styrene resin (ABS resin).

The skin material 20 is provided on the surface side of the base material 14. The skin material 20 is laminated on the surface of the base material 14 and covers the opening 16 of the base material 14 . Although not shown, the peripheral edge portion of the skin material 20 is wound around the back side of the base material 14 so as to wrap around the outer peripheral end of the base material 14, and is fixed to the back surface of the base material 14. The skin material 20 constitutes the design surface of the display panel 10.

The skin material 20 includes a light-transmitting layer 22 and a light-blocking layer 24. The light blocking layer 24 is provided on the back surface of the light transmitting layer 22. The light-transmitting layer 22 is made of synthetic resin. Examples of materials for the light-transmitting layer 22 and the light-shielding layer 24 include stretchable materials such as polyvinyl chloride (PVC), thermoplastic urethane (TPU), and thermoplastic olefin (TPO), and polycarbonate (PC). An example is film.

The light-shielding layer 24 is formed of a coating film containing a black pigment, and has light-shielding properties. The light-transmitting layer 22 contains a pigment, but the content thereof is relatively small, and has light-transmitting properties. A window hole 26 is formed in the light shielding layer 24 so as to correspond to the opening 16 of the base material 14 . That is, in the skin material 20, the light shielding layer 24 is provided in a portion facing the surface of the base material 14, while the light shielding layer 24 is not provided in a portion of the base material 14 corresponding to the opening 16.

A portion of the skin material 20 that corresponds to the opening 16 of the base material 14 forms a light-transmitting region 28 that transmits light. The light-transmitting region 28 of the skin material 20 mainly constitutes the light-transmitting material portion 30 of the vehicle interior component 7. The light-transmitting material portion 30 is a portion through which light of an image displayed on the screen 52 of the display device 50 is transmitted. The light-transmitting region 28 of the skin material 20 functions as the display window 12.

As also shown in FIG. 3, the display device 50 has a screen 52 that displays images. The display device 50 of this example is a flat panel display (FPD) with a thin and flat screen. Examples of flat panel displays (FPD) include liquid crystal displays and organic EL (Electro Luminescence) displays. The display device 50 has a touch panel and is configured to receive touch operations.

The display device 50 of this example is directly attached to the circuit board 54. The circuit board 54 is arranged on the back side of the display device 50. The circuit board 54 is fixed to the plurality of bosses 18 on the base material 14 using tapping screws 56. The circuit board 54 is provided with a control circuit (not shown). The control circuit is a circuit for controlling the operation of the display device 50. The control circuit is basically composed of an IC (Integrated Circuit).

In this way, the display device 50 of this example is fixed to the display panel 10 (base material 14) via the circuit board 54. The display device 50 is arranged within the opening 16 of the base material 14. Then, the screen 52 of the display device 50 is bonded to the back surface of the light-transmitting area 28 in the skin material 20 by so-called optical bonding. An optical adhesive material 62 is used for optical bonding.

The back surface of the light-transmitting region 28 in the skin material 20 and the screen 52 of the display device 50 are bonded via the intervening layer 60. The refractive index of the intervening layer 60 is approximately 1.4 to 1.5, which is higher than the refractive index of air (approximately 1.0) of the transparent region 28 of the skin material 20 (approximately 1.4 to 1.5). Close to 6). The intervening layer 60 is filled without any gap between the back surface of the light-transmitting region 28 in the skin material 20 and the screen 52 of the display device 50. The intervening layer 60 is made of a colorless and transparent optical adhesive material 62.

An optical adhesive is used as the optical adhesive material 62. Optical adhesive is also called OCR (Optical Clear Resin). Several classifications of optical adhesives are known, such as silicone-based, acrylic-based, and acrylic-modified silicone-based adhesives, and any classification of optical adhesives may be used.

Further, as the optical adhesive material 62, an optical adhesive sheet may be used. The optical adhesive sheet is also called OCA (Optical Clear Adhesive). Several classifications of optical adhesive sheets are known, such as silicone-based, acrylic-based, and urethane-based, and any classification of optical adhesive sheets may be used.

The intervening layer 60 and the light-transmitting region 28 of the skin material 20 constitute the light-transmitting material portion 30 of the vehicle interior component 7. That is, the light-transmitting material section 30 includes the intervening layer 60. The light-transmitting material section 30 of this example is constituted by the light-transmitting region 28 of the skin material 20 and the intervening layer 60. The intervening layer 60 constitutes the back surface of the transparent material section 30. The screen 52 of the display device 50 contacts the back surface of the transparent material section 30.

In the vehicle interior component 7 having the above configuration, when the power is turned on, the display device 50 operates and a predetermined image is displayed on the screen 52. The light of the image displayed on the screen 52 passes through the intervening layer 60 and is projected onto the skin material 20 from the back side. As a result, an image is projected on the surface of the skin material 20. The image may be, for example, a design image that adds a design accent to interior materials, a menu screen of an in-vehicle system, an icon indicating predetermined information, or the like.

- Manufacturing method for vehicle interior parts -
As shown in FIG. 4, the method for manufacturing the vehicle interior component 7 includes a skin material lamination step ST1, a transparent region formation step ST2, an intervening layer lamination step ST3, and a display device arrangement step ST4.

First, a skin material lamination step ST1 is performed. As shown in FIG. 5, in the skin material lamination step ST1, the skin material 20 is laminated on the surface of the base material 14. More specifically, the skin material 20 is provided so as to cover the front surface of the base material 14 and cover the opening 16 . Then, the peripheral edge portion of the skin material 20 is wound around the back side of the base material 14 so as to wrap around the outer peripheral portion of the base material, and is fixed to the back surface of the base material 14. At this time, the light-transmitting region 28 has not yet been formed on the skin material 20.

Next, a transparent region forming step ST2 is performed. As shown in FIG. 6, in the light-transmitting region forming step ST2, a light-transmitting region 28 is formed in the skin material 20 at a portion corresponding to the opening 16 of the base material 14. Specifically, by irradiating the skin material 20 with the laser beam LS from the back side of the base material 14 through the opening 16, the portion of the light shielding layer 24 corresponding to the opening 16 of the base material 14 is exposed. Then, a window hole 26 is formed in the light shielding layer 24. By doing so, a light-transmitting region 28 is formed in the skin material 20.

Next, an intervening layer stacking step ST3 is performed. As shown in FIG. 7, the intervening layer lamination step ST3 is performed before the display device arrangement step ST4. In the intervening layer lamination step ST3 of this example, the intervening layer 60 is laminated on the back surface of the skin material 20. More specifically, the intervening layer 60 is provided on the back surface of the light-transmitting region 28 in the skin material 20 via the opening 16 of the base material 14. As a result, a light-transmitting material section 30 consisting of the light-transmitting region 28 of the skin material 20 and the intervening layer 60 is formed.

Specifically, the intervening layer 60 is formed using the optical adhesive material 62 by applying OCR or pasting OCA to the back surface of the light-transmitting region 28 of the skin material 20. In the intervening layer lamination step ST3, the intervening layer 60 may be provided on the screen 52 of the display device 50 instead of on the back surface of the light-transmitting region 28 in the skin material 20. As described above, the intervening layer 60 provided here has a property of transmitting light with a refractive index closer to the refractive index of the light-transmitting region 28 of the skin material 20 than the refractive index of air.

Next, a display device arrangement step ST4 is performed. As shown in FIG. 8, in the display device placement step ST4, the display device 50, which has been attached to the circuit board 54 in advance, is brought close to the base material 14 from the back side thereof. Then, the display device 50 is arranged within the opening 16 of the base material 14 so that the screen 52 faces the light-transmitting region 28 of the skin material 20.

At this time, the screen 52 of the display device 50 is pressed against the intervening layer 60 to adhere the screen 52 of the display device 50 and the light-transmitting region 28 of the skin material 20 via the intervening layer 60. That is, the screen 52 of the display device 50 is brought into contact with the back surface of the transparent material section 30 . In this state, the circuit board 54 is fixed to each boss 18 of the base material 14 with tapping screws 56. Thereafter, a process (for example, ultraviolet irradiation or heat treatment) for curing the optical adhesive material 62 forming the intervening layer 60 is performed as necessary.

In the manner described above, the vehicle interior component 7 can be manufactured.

-Features of the embodiment-
In the vehicle interior component 7 of this embodiment, a display device 50 having a screen 52 is used. The screen 52 of the display device 50 comes into contact with the back surface of the translucent material section 30, which is formed by a portion of the skin material 20 that corresponds to the opening 16 of the base material 14. The light of the image displayed on the screen 52 of the display device 50 passes through the transparent material section 30 and is visually recognized by the user from the outside. At this time, since the light of the image does not pass through a transparent resin plate, a diffuser plate, or any other transparent plate, it is difficult to be diffused before being projected onto the skin material 20. Therefore, the image on the display device 50 is displayed relatively clearly on the skin material 20. Therefore, in the vehicle interior component 7, the image displayed by the display device 50 can be clearly seen.

In the vehicle interior component 7 of this embodiment, the intervening layer 60 is interposed between the screen 52 of the display device 50 and the skin material 20. The intervening layer 60 has a refractive index closer to the refractive index of the portion of the skin material 20 that constitutes the translucent material portion 30 than the refractive index of air. When an air layer is interposed between the screen 52 of the display device 50 and the skin material 20, the difference in refractive index between the skin material 20 and the air layer is relatively large. Therefore, the light of the image displayed on the screen 52 of the display device 50 causes refraction and diffuse reflection at the interface between the skin material 20 and the air layer. Therefore, the visibility of the image projected on the skin material 20 is reduced. On the other hand, when the intervening layer 60 is interposed between the screen of the display device 50 and the skin material 20, the difference in refractive index between the skin material 20 and the intervening layer 60 is relatively small. According to this, the light of the image displayed on the screen 52 of the display device 50 is unlikely to be refracted or diffusely reflected at the interface between the skin material 20 and the intervening layer 60. Therefore, the visibility of the image projected on the skin material 20 can be improved.

In the vehicle interior component 7 of this embodiment, the intervening layer 60 is made of an optical adhesive material 62. The screen 52 of the display device 50 and the skin material 20 are bonded together through an intervening layer 60. Thereby, the screen 52 of the display device 50 can be suitably brought into close contact with the back surface of the transparent material section 30. This is advantageous in improving the visibility of the image projected on the skin material 20.

In the method for manufacturing the vehicle interior part 7 in this embodiment, the skin material 20 is provided on the surface side of the base material 14 and the opening 16 of the base material 14 is covered with the skin material 20. Thereafter, a light-transmitting region 28 is formed in the skin material 20 at a portion corresponding to the opening 16 of the base material 14. By doing so, the light-transmitting region 28 of the skin material 20 can be provided to correspond to the opening 16 of the base material 14. Thereby, it is possible to suppress the positional shift of the light-transmitting region 28 of the skin material 20 with respect to the opening 16 of the base material 14. In this method of manufacturing the vehicle interior part 7, the display device 50 is arranged within the opening 16 of the base material 14, and the screen 52 of the display device 50 is mainly formed by the light-transmitting region 28 of the skin material 20. It is brought into contact with the back surface of the transparent material section 30. By doing so, as described above, the image of the display device 50 is displayed relatively clearly on the skin material 20.

In the method for manufacturing the vehicle interior component 7 in this embodiment, the intervening layer 60 is provided on the back surface of the light-transmitting region 28 of the skin material 20 or on the screen 52 of the display device 50. The intervening layer 60 has a refractive index closer to the refractive index of the portion of the skin material 20 that constitutes the translucent material section 30 than the refractive index of air, and is formed between the screen 52 of the display device 50 and the skin material 20. intervene. According to this, the light of the image displayed on the screen 52 of the display device 50 is unlikely to be refracted or diffusely reflected at the interface between the skin material 20 and the intervening layer 60. Therefore, the visibility of the image projected on the skin material 20 can be improved.

In the method for manufacturing the vehicle interior component 7 in this embodiment, the intervening layer 60 is formed using the optical adhesive material 62. The screen 52 of the display device 50 and the skin material 20 are bonded together through an intervening layer 60. According to this, the screen 52 of the display device 50 can be suitably brought into close contact with the back surface of the transparent material section 30. This is advantageous in improving the visibility of the image projected on the skin material 20.

-First modification-
As shown in FIG. 9, in the vehicle interior component 7 of this first modification, the display device 50 is fixed to the base material 14 of the display panel 10 using a mounting plate 70 that is separate from the circuit board 54. As shown in FIG. The display device 50 is attached to a mounting plate 70. The mounting plate 70 is fixed to a plurality of bosses 19 provided on the back surface of the base material 14 with tapping screws 73. The circuit board 54 is arranged on the back side of the mounting plate 70. The display device 50 is connected to the circuit board 54 via wiring 72.

The structure of the vehicle interior component 7 of this first modification is suitable when the portion of the display panel 10 corresponding to the display window 12 is curved. In this case, a flexible display having flexibility may be employed as the display device 50. In the case of a flexible display, the display device 50 itself is bent into a shape that follows the curved shape of the display panel 10, and the entire screen is brought into contact with the back surface (intervening layer 60) of the transparent material section 30, and the base material 14 is bent. It is possible to arrange it within the opening 16.

-Second modification-
As shown in FIG. 10, in the vehicle interior component 7 of this second modification, the display device 50 is directly held on the base material 14. At least a pair of claw pieces 76 are provided at the peripheral edge portion of the opening 16 in the base material 14 . The pair of claw pieces 76 protrude from the back side of the base material 14 and are provided at positions facing each other. The display device 50 is inserted into the opening 16 from the back side of the base material 14 while bending each claw piece 76 . When the display device 50 is completely inserted into the opening 16, the claw pieces 76 elastically return to hold the display device 50 in the opening 16.

The structure of the vehicle interior component 7 of this second modification is also suitable when the portion of the display panel 10 corresponding to the display window 12 is curved. In this case, a flexible display having flexibility may be employed as the display device 50. Further, according to the second modified example of the vehicle interior component 7, since a mounting plate separate from the circuit board 54 is not used, the number of parts of the vehicle interior component 7 is reduced compared to the first modified example. Less is enough.

《Other embodiments》
In the above embodiment, the screen 52 of the display device 50 is bonded to the back surface of the light-transmitting area 28 in the skin material 20 via the intervening layer 60 made of the optical adhesive material 62, but the present invention is not limited to this. For example, the intervening layer 60 may be made of a resin other than the optical adhesive material 62 that has a refractive index closer to the refractive index of the light-transmitting region 28 of the skin material 20 than that of air.

Furthermore, the screen 52 of the display device 50 may directly contact the back surface of the light-transmitting region 28 in the skin material 20. In this case, the intervening layer 60 is not provided between the back surface of the light-transmitting region 28 in the skin material 20 and the screen 52 of the display device 50, and the light-transmitting material portion 30 of the vehicle interior component 7 is transparent to the skin material 20. It is composed of only the light area 28.

In short, at least the part of the skin material 20 corresponding to the opening 16 of the base material 14 mainly constitutes the light-transmitting material part 30 that transmits light in the display panel 10, and the back surface of the light-transmitting material part 30 It is sufficient that the screen 52 of the display device 50 is in contact with the screen 52 of the display device 50. Here, "consisting mainly of the light-transmitting material part 30" means that the main structure of the light-transmitting material part 30 is the skin material 20, and the light-transmitting material part 30 is thicker than the skin material 20. This means that it does not contain plate-like objects.

In the above embodiment, the display panel 10 may include a cushioning material in addition to the base material 14 and the skin material 20. The cushioning material is provided between the base material 14 and the skin material 20. An opening is formed in this cushion material. The opening of the cushion material is provided at a position corresponding to the opening of the base material.
