Description

[Technical field]

[0001] The present invention relates to a vehicle interior structure, and more particularly to an interior lighting device for a vehicle. [Background technology]

[0002] In the field of vehicle interior structure, there is a technology related to an interior lighting device that is installed on the instrument panel (hereinafter referred to as "instrument panel") in the vehicle cabin or its surroundings to be used as indirect lighting. Indirect lighting illuminates the interior with indirect light that is generated by reflecting light from a light source off vehicle-mounted components, etc., and is sometimes used as atmospheric lighting to create a comfortable space in the vehicle cabin or to make the limited space in the vehicle cabin appear larger by placing the indirect lighting in a position that is out of the driver's field of vision.

[0003] Patent Document 1 discloses a vehicle lighting device that has a lighting function and an illumination function that can effectively produce a display that attracts passengers. This vehicle lighting device is said to be able to provide both lighting and illumination displays while sharing the light source by providing a dividing optical element that divides the light emitted from the light source into light directed toward an illumination light-emitting section for lighting and light directed toward an illumination light-emitting section for illumination display.

[0004] [Patent Document 1] JP 2014-189101 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, in a lighting device that uses a light source disposed in a part of the interior of a vehicle as atmospheric lighting, there is a structure that aims to spread the light so that the interior of the vehicle appears larger. However, when a light source is disposed in a position corresponding to each of the parts that are to be illuminated, problems such as a lack of space and an increase in cost arise. On the other hand, it is also possible to provide a separate light guide device so that multiple parts that are to be illuminated share one light source, but this may result in the entire device becoming large. As a result, not only will there be a lack of space and an increase in cost, but the device may be in the passenger's field of vision due to its large size, and in such cases, improvements may be required in terms of design as well.

[0006] Therefore, this specification provides a vehicle interior structure that can improve the atmosphere inside the vehicle cabin while avoiding a lack of space and an increase in costs. [Means for solving the problem]

[0007] The vehicle interior structure disclosed in this specification comprises a light source, a shielding member disposed between the light source and the field of vision of a vehicle occupant, and a reflective member that reflects light emitted from the light source and spread in multiple directions, and is characterized in that the surface of the reflective member in an area extending from the area directly irradiated by the light to the periphery is provided with unevenness extending in the vehicle width direction or the vehicle fore-and-aft direction. Effect of the Invention

[0008] According to the vehicle interior structure disclosed in this specification, by using only one light source, it is possible to save space in the limited vehicle interior. In addition, the shielding member prevents the light source from entering the field of view of the occupants, eliminating inconvenience in terms of design. In addition, the shape of the reflective member makes the vehicle interior space look larger, improving the atmosphere inside the vehicle interior. [Brief description of the drawings]

[0009] [Figure 1] 1 is a schematic diagram of a vehicle interior structure according to an embodiment, as viewed from inside a vehicle compartment. [Diagram 2] 2 is a cross-sectional view taken along line AA in FIG. 1. [Diagram 3]FIG. 2 is a cross-sectional view of FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, a vehicle interior structure will be described with reference to the drawings. In each drawing, "Fr", "Up", and "Rh" indicate the front, upper, and right side of the vehicle, respectively.

[0011] FIG. 1 is a schematic diagram of a vehicle interior structure according to an embodiment as viewed from inside the vehicle cabin. More specifically, FIG. 1 is a diagram showing the front of a vehicle cabin of a vehicle 10 as an example of a vehicle interior structure according to an embodiment. As shown in FIG. 1, an instrument panel 12 (hereinafter referred to as "instrument panel 12"), which is an interior member, is disposed under a windshield (not shown) of the vehicle 10 and in front of the driver's seat and passenger seat. Also, a steering wheel 14 is disposed in front of the driver's seat and behind the instrument panel 12 (i.e., on the side closer to the driver). The vehicle 10 further includes doors 16 on the left and right, and the doors 16 have door trims 18 as interior trim parts on the interior side thereof.

[0012] In the vehicle 10, an air conditioner is disposed inside the instrument panel 12 (not shown). Furthermore, an air outlet 20, which is part of the air conditioner and directs conditioned air into the vehicle cabin, is disposed on the surface of the instrument panel 12 (i.e., the surface facing the occupant). A light source 22 is provided near the air outlet 20, behind the air outlet 20 and on the outer side in the vehicle width direction. One light source 22 is provided on each of the driver's seat side and the passenger seat side of the instrument panel 12. The light source 22 is disposed in a position that is not visible to the occupant, and is therefore shown in FIG. 1 surrounded by a dashed line as a hidden line. The light source 22 is a light-emitting diode in this example, but is not limited thereto and may be a light bulb, an organic electroluminescence (OLED), or the like.

[0013] In FIG. 1, the periphery of the air outlet 20 of the passenger seat air conditioner and the light source 22 is surrounded by a two-dot chain line C to show the irradiation range of the light emitted from the light source 22, and an enlarged view of the encircled area is shown. As shown in the enlarged view C of FIG. 1, the light emitted from the light source 22 (not shown in the enlarged view C) spreads in the directions of the arrows 24a, 24b, and 24c surrounded by a dashed line and shown in light ink. The arrows 24a, 24b, and 24c typically show the irradiation range from the light source 22. More specifically, the irradiation range 24a shows the range spreading in the front-rear direction of the vehicle 10, the irradiation range 24b shows the range spreading in the up-down direction of the vehicle 10, and the irradiation range 24c shows the range spreading in the vehicle width direction (i.e., the left-right direction) of the vehicle 10. That is, in the vehicle interior structure according to the embodiment, one light source 22 can illuminate three directions, namely, front-rear, up-down, and left-right. The details of the irradiation range will be described below using the AA and BB cross sections.

[0014] Fig. 2 is a cross-sectional view taken along line AA in Fig. 1. As shown in Fig. 2, the light source 22 is installed on the rear surface of the instrument panel 12. Therefore, the light source 22 is out of the range visible to the eyes 30 of the occupant (indicated by the two-dot chain arrow D in Fig. 2). That is, in the vehicle interior structure of the embodiment, the instrument panel 12 functions as a shielding member provided between the light source 22 and the field of vision of the vehicle occupant.

[0015] As shown in FIG. 2, a lens 26 is provided behind the light source 22 in the longitudinal direction of the vehicle 10 (i.e., on the side closer to the occupant) so as to surround the periphery of the light source 22. The lens 26 has a function of adjusting the irradiation direction of the light emitted from the light source 22 and diffusing the light emitted from the light source 22 in approximately one direction up, down, left and right. In FIGS. 2 and 3, the lens 26 is shown as a dark black portion. In FIG. 2, the irradiation range of the light from the light source 22 is shown as a light black area surrounded by a dashed line, and the light is directly irradiated onto an area extending in the longitudinal direction of a decorative panel 28, which is a member having an optical film provided on a part of the instrument panel 12. The light reflected by the decorative panel 28 is recognized by the eyes 30 of the occupant.

[0016] Fig. 3 is a cross-sectional view taken along line BB in Fig. 1. In Fig. 3, a part of the instrument panel 12 is indicated by a broken line. Since the decorative panel 28 is not provided in the part of the instrument panel 12 indicated by the broken line, the decorative panel 28 functions solely as a shielding member provided between the light source 22 and the field of vision of the occupant. As shown in Fig. 3, the light emitted from the light source 22 has its irradiation direction adjusted by a lens 26 provided so as to surround the periphery of the light source 22, and the light is reflected and reaches the instrument panel 12 and the door trim 18. The light is then reflected by the decorative panels 28 provided on the instrument panel 12 and the door trim 18, respectively.

[0017] As described above, in the vehicle interior structure of the embodiment, the decorative panel 28 is provided as a member provided with an optical film on at least a peripheral portion of the area directly irradiated with light from the light source 22 and an area extending further outward from the peripheral portion of the door trim 18. In FIG. 3, a part of the decorative panel 28 is surrounded by a two-dot chain line E and shown as an enlarged view. As shown in the enlarged view E, a groove (more specifically, an uneven shape extending in the vehicle width direction or the vehicle front-rear direction) is provided on the surface of the optical film. Therefore, light travels while being reflected in the groove on the surface of the optical film. In the enlarged view E, the manner in which light travels while being reflected is shown by a light-ink arrow. In this way, the light emitted from the light source 22 spreads not only to the area directly irradiated but also to the surrounding area, so that the irradiation range is wider. As a result, a visual effect with a sense of depth is obtained along with the spread of light, and the interior of the vehicle can be made to look wider. 3, the illumination range from the light source 22 is roughly indicated by a dashed line and light ink. As described above, the light source 22 is outside the range of the arrow D representing the field of vision of the occupant, but the illumination range is set at a position intersecting with the arrow D, so that the atmosphere in the vehicle cabin can be improved without causing any inconvenience in terms of design.

[0018] 3 shows the illumination range 24a in FIG. 1 (i.e., the range extending in the front-rear direction on the door trim 18 of the vehicle 10), but the illumination range 24c can also be widened by providing an optical film in a similar manner. An optical film may also be provided in the illumination range 24b. Although it is not necessary to provide an optical film in the range directly illuminated by the light from the light source 22, providing an optical film can provide an overall unified design.

[0019] 1 to 3, in the vehicle interior structure according to the embodiment, the light source 22 is disposed in a position not visible to the occupants, and one light source 22 illuminates three directions, namely, front / rear, up / down, and left / right, and also illuminates two areas, the instrument panel 12 and the door trim 18. As a result, the structure makes it possible to improve the atmosphere in the vehicle cabin, in particular to make the vehicle cabin look more spacious, while avoiding a lack of space and an increase in costs.

[0020] The above description is merely an example, and the vehicle interior structure disclosed in this specification may include a shielding member between the light source and the field of vision of the vehicle occupant, and a reflecting member having an uneven surface that reflects light emitted from one light source and spread in multiple directions. That is, other configurations may be changed as appropriate. For example, in the embodiment, the light source 22 is installed on the back of the air outlet 20 of the air conditioner, but this is not limited thereto. The light source 22 may be installed in any location that is outside the field of vision of the occupant and where the light from the light source 22 does not directly enter the eyes of the occupant, and may be installed in, for example, the bottom of the instrument panel 12 or a part of the door trim 18.
