  Hereinafter, a preferred embodiment of a vehicle interior module according to the present invention will be described according to the attached drawings.

  FIG. 1 is an external view of a door 14 in which a vehicle interior module 10 according to the embodiment is applied to a part of an interior wall portion 16 of a door 14 of a vehicle body 12.

  2 is an external view of the vehicle interior module 10 shown in FIG. 1, FIG. 3 is a cross-sectional view of the region A of the vehicle interior module 10, and FIG. FIG.

  As shown in FIG. 3, the vehicle interior module 10 has a bent glass plate 18, a metal reinforcing plate 20, and an adhesive 26 for bonding the bent glass plate 18 and the reinforcing plate 20. The bent glass plate 18 has a surface (first surface) 18A that forms a part of the wall surface of the interior wall portion 16 (see FIG. 1), and a back surface (first back surface) 18B opposite to the surface 18A. The bent glass plate 18 has a decorative surface on the back surface 18B as described later. In the embodiment, the bent glass plate 18 is a glass plate formed in a curved shape along the shape of the curved wall surface.

  The bending glass plate 18 is curved in a three-dimensional shape, and has, for example, a curvature radius of 1000 R or more and 100000 R or less (1000 mm or more and 100000 mm or less). The bent glass plate 18 may include a bent portion in part. Further, the bending direction of the bent glass plate 18 may project to the side of the back surface 18B as shown in FIG. 3, or may project to the side of the surface 18A, or may include both.

  The reinforcing plate 20 includes a front surface (second front surface) 20A attached to the rear surface 18B of the bent glass plate 18 via the adhesive 26 and a rear surface (second rear surface) 20B opposite to the front surface 20A. It has the bead 20D which protrudes in the opposite direction to the glass plate 18.

  The reinforcing plate 20 is provided to ensure the strength of the bent glass plate 18, but in order to ensure the strength, it is desirable that the distance between the bent glass plate 18 and the reinforcing plate 20 be as constant as possible.

  By providing the bead 20D on the back surface 20B of the reinforcing plate 20, the rigidity of the reinforcing plate 20 can be lowered at the portion of the bead 20D. As a result, the reinforcing plate 20 can be bent along the bending glass plate 18 starting from the bead 20D. Since the reinforcing plate 20 can be prevented from returning flat due to the reaction force, the distance between the bent glass plate 18 and the reinforcing plate 20 can be made substantially constant. Therefore, the vehicle interior module 10 including the bending glass 18 having the decorative surface can secure its strength.

  Since the bead 20D protrudes in the opposite direction to the bent glass plate 18, the bead 20D can prevent the bent glass plate 18 from being damaged.

  FIG. 4 shows a more preferable cross-sectional view of the vehicle interior module 10. As shown in FIG. 4, the vehicle interior module 10 has a covering member 22 in addition to the bent glass plate 18, the metal reinforcing plate 20 and the adhesive 26.

  The bent glass plate 18 has a front surface 18A, a back surface 18B, and a peripheral portion (first peripheral portion) 18C connecting the front surface 18A and the back surface 18B.

  The bent glass plate 18 is a well-known tempered glass which has been subjected to a chemical strengthening treatment or an air-cooling strengthening treatment, and its thickness (t1) is 4 to 6 mm as an example. The bent glass plate 18 is not limited to tempered glass, and may be non-tempered glass. Further, the thickness (t1) of the bent glass plate 18 is not limited to the above-mentioned thickness, and may be a thickness required according to the place where the vehicle interior module 10 is applied.

  In addition, in the bent glass plate 18, a faceted decorative surface including a plurality of concave portions 18D and convex portions 18E is formed on the back surface 18B. The design of the vehicle interior module 10 is enhanced by viewing the back surface 18B, which is a decorative surface, through the surface 18A. The uneven shape (also referred to as a facet pattern) of the back surface 18B which is a decorative surface is not a uniform shape over the entire surface of the back surface 18B, but the curved surface, the inclined surface and the flat surface of the bent glass plate 18 are more three-dimensionally recognized As shown in FIG. 2, the shape is changed according to the curved surface, the inclined surface, the flat surface, etc. of the bent glass plate 18 as shown in FIG.

  Moreover, it is preferable to form the coating layer 24 in the back surface 18B of the bending glass plate 18. The coating layer 24 can be exemplified by silver deposited. Thus, the back surface 18B of the bent glass plate 18 can be configured as a mirror surface, so that the design of the vehicle interior module 10 can be further improved. Alternatively, the coating layer 24 may be formed by baking a paint on the back surface 18B. Thereby, the bending glass plate 18 can be comprised in color glass, and the designability of the vehicle interior module 10 improves also in this case.

  The reinforcing plate 20 has a front surface 20A, a back surface 20B, and a peripheral portion (second peripheral portion) 20C connecting the front surface 20A and the back surface 20B.

  The reinforcing plate 20 can reinforce the bent glass plate 18 as described above, and can function as a support member for causing the vehicle body 12 to support the bent glass plate 18. The reinforcing plate 20 is made of metal such as iron, aluminum or stainless steel, for example, and its thickness (t2) is, for example, 1 to 2 mm. The thickness (t2) of the reinforcing plate 20 is not limited to the above thickness.

  The reinforcing plate 20 may be bonded to the back surface 18B of the bent glass plate 18 via an adhesive 26 such as, for example, a urethane adhesive. The adhesive 26 is partially applied to the back surface 18B of the bent glass plate 18 at a plurality of places, but may be applied to the entire surface of the back surface 18B. The thickness (t3) of the adhesive 26 is, for example, 1 to 2 mm, but is not limited to this thickness.

  The covering member 22 is made of, for example, a urethane resin, and a covering portion (first covering portion) 22A covering the peripheral portion 18C of the bent glass plate 18 and a covering portion covering the peripheral portion 20C of the reinforcing plate 20 (second covering Part) at least 22B. The thickness (t4) of the covering portion 22A and the covering portion 22B is, for example, 1 to 2 mm, but is not limited to this thickness (t4).

  The covering member 22 is manufactured, for example, by vacuum casting. Specifically, a silicon rubber type or a metal type of iron, aluminum or the like is attached to the bent glass plate 18 to which the reinforcing plate 20 is bonded. Next, a silicone rubber mold or a metal mold is placed in the vacuum chamber of the vacuum casting machine. Next, the urethane resin is cured in a vacuum state while injecting a liquid urethane resin into a silicone rubber mold or a metal mold. Finally, the silicon rubber mold or metal mold is removed from the bent glass plate 18 to which the reinforcing plate 20 is bonded. Thus, the covering member 22 shown in FIG. 4 is formed.

  According to the vehicle interior module 10 of the embodiment configured as described above, since the bent glass plate 18 having the decorative surface formed on the back surface 18B is provided, the design can be improved. Further, since the bent glass plate 18 is reinforced by the reinforcing plate 20, the strength corresponding to the interior wall portion 16 of the vehicle body 12 can be secured. Further, since the reinforcing plate 20 functions as a support member for supporting the bent glass plate 18 on the vehicle body 12, the assemblability of the vehicle interior module 10 to the vehicle body 12 can be improved. Furthermore, the cover portion 22A of the cover member 22 covers and protects the peripheral portion 18C of the bent glass plate 18, and the cover portion 22B covers and protects the peripheral portion 20C of the reinforcing plate 20. The assemblability of the module 10 can be further improved. Therefore, according to the vehicle interior module 10 of the embodiment, the strength can be secured while improving the designability, and the assemblability to the vehicle body 12 can be improved.

  The covering member 22 preferably has a covering portion (third covering portion) 22C for covering at least a part of the back surface 18B of the bent glass plate 18 and at least a part of the surface 20A of the reinforcing plate 20 as shown in FIG. . The integrity of the bent glass plate 18 and the reinforcing plate 20 is enhanced by the covering portion 22C, so that the assemblability of the vehicle interior module 10 to the vehicle body 12 can be further improved.

  Moreover, it is preferable that the transparent film member 28 made of a plastic, for example, is stuck on the surface 18A of the bending glass plate 18. The film member 28 can protect the surface 18A which is a glass surface. The thickness (t5) of the film member 28 is, for example, 80 to 100 μm, but is not limited to this thickness (t5).

  The covering member 22 preferably further includes a covering portion (fourth covering portion) 22D for covering the peripheral portion 28A of the film member 28. By covering the peripheral portion 28A of the film member 28 with the covering portion 22D, the peripheral portion 28A can be prevented from peeling off from the surface 18A. Although the coating | coated length (a) of peripheral part 28A by coating | coated part 22D is 0.6-1.0 mm, for example, it is not limited to this length (a).

  Further, it is preferable that the base plate 30 be adhered to the back surface 20B of the reinforcing plate 20. The base plate 30 is adhered to the reinforcing plate 20 via an adhesive 32 such as, for example, a urethane adhesive. The vehicle interior module 10 is fixed to the vehicle body 12 through the base plate 30. At that time, preferably, the base plate 30 is provided with a positioning member (not shown) such as a pin for positioning the vehicle interior module 10 with respect to the vehicle body 12. Further, it is preferable that the vehicle body 12 be provided with a fitting hole into which the above-mentioned positioning member is fitted. Thus, according to the vehicle interior module 10 of the embodiment, the vehicle interior module 10 can be mounted on the vehicle body 12 only by fitting the positioning member of the base plate 30 into the fitting hole of the vehicle body 12. The above is description of the vehicle interior module 10 of embodiment based on each figure.

  Although the above-mentioned embodiment explained the example which applied vehicle interior module 10 to a part of interior wall part of door 14, the vehicle interior module of the present invention is a dashboard (not shown) of vehicle body 12, an armrest (not shown) It can also be applied to a part of the interior wall part such as a console box (not shown) or the like.

  Further, the color of each member constituting the vehicle interior module 10 is not particularly limited. However, in the case of a vehicle interior module in which the coating layer 24 is not formed on the back surface 18B of the bent glass plate 18, the adhesive 26 and the reinforcing plate 20 are seen through the bent glass plate 18, which is not preferable from the viewpoint of design. So, in the case of the vehicle interior module of this form, the covering member 22 is made black, for example. Thus, the covering portion 22C of the covering member 22 can prevent the adhesive 26 and the reinforcing plate 20 from being seen through, so that the design of the vehicle interior module 10 can be enhanced.

  Furthermore, in the vehicle interior module 10 of the embodiment, the back surface 18B of the bent glass plate 18 constitutes a decorative surface, but the front surface 20A of the reinforcing plate 20 may also constitute a decorative surface. By combining the decorative surface on the bent glass plate 18 side with the decorative surface of the reinforcing plate 20, the design of the vehicle interior module 10 can be further enhanced. In this case, of course, the covering member 22 is made transparent so that the decorative surface of the reinforcing plate 20 can be seen through.
