Description

  The present invention relates to a vehicle interior structure that defines a vehicle compartment provided in a vehicle or is exposed to the vehicle compartment.

  As a vehicle interior structure, FIG. 2 of Patent Document 1 discloses, for example, an interior skin material 1 that covers a ceiling surface, and pattern elements 3A, 3B, and 3C formed on the surface of the interior skin material 1 on the passenger compartment side. . Here, for example, the pattern elements 3A and 3B are invisible and the pattern element 3C is visible in daylight, while the pattern elements 3A and 3B are excited to emit light under ultraviolet light 6 (black light) at night, for example. And become visible. Furthermore, since the pattern element 3A has a phosphorescent characteristic and the pattern element 3B does not have a phosphorescent characteristic, for example, when the ultraviolet lamp 6 is turned off at night, the pattern element 3B becomes invisible and the pattern element 3A Visible continuously for 2 hours. With such a configuration, an interior impression different from that of the daytime can be given to the occupant by turning on the ultraviolet lamp 6 at night, and a further change in the interior impression can be caused by turning off the ultraviolet lamp 6.

No. 08-000194

  However, in Patent Document 1, for example, when the ultraviolet lamp 6 is turned on at night, not only the pattern element 3A but also the pattern element 3B can be visually recognized. In other words, when the illuminating ultraviolet lamp 6 is turned off, the occupant has already recognized the pattern element 3B, so the degree of change in the interior impression is low, and the occupant's satisfaction may be reduced. In addition, for example, the light emission time or remaining period (for example, 2 hours) of the pattern element after the ultraviolet lamp 6 is turned off at night depends on the light storage characteristics of the pattern element 3A. In other words, the occupant cannot control the light emission time of the pattern element 3 </ b> A, and may give the occupant discomfort.

  One object of the present invention is to provide an interior structure for a vehicle that can suppress a passenger's satisfaction or a decrease in comfort. Other objects of the present invention will become apparent to those skilled in the art by referring to the aspects and preferred embodiments exemplified below and the accompanying drawings.

  In the following, in order to easily understand the outline of the present invention, embodiments according to the present invention will be exemplified.

A first aspect according to the present invention has a vehicle interior side surface on which a predetermined pattern is formed and a back surface opposite to the vehicle interior side, and the surface is irradiated with ultraviolet rays by a first light emitting unit. An outer surface portion that sometimes makes the predetermined pattern visible,

  The first light emitting unit makes it possible to visually recognize a predetermined pattern such as a picture, a pattern, or a pattern, and the second light emitting unit allows a light source such as a color to be seen through the outer surface. Since the light source of the 2nd light emission part can be controlled independently, a passenger's satisfaction or the fall of comfort can be controlled.

  In the first aspect, the light irradiated by the second light emitting unit may be blocked when the ultraviolet light is irradiated by the first light emitting unit.

  Since the transmission of the light from the light source of the second light emitting unit through the outer surface part is blocked, the predetermined pattern can be more reliably visually recognized by the first light emitting unit. Furthermore, before switching from the first light-emitting part to the second light-emitting part, the transmitted light from the second light-emitting part is not visible, the degree of change in the interior impression is high, and the passenger's satisfaction is improved To do.

In the first aspect, the vehicle interior structure may further include a plurality of hollow structures disposed between the outer surface portion and the second light emitting portion,
The outer surface portion and the hollow structure may have elasticity.

  Since the light from the light source of the second light emitting part reaches the outer surface part through the hollow structure, the light intensity of the light source such as color is expressed by the second light emitting part, for example, transparent light, soft light, etc. The impression can be given to the occupant. Note that a predetermined pattern such as a picture, a pattern, or a pattern can be formed by the arrangement pattern of the hollow structure. In addition, the elasticity of the outer structure is emphasized by the elasticity of the hollow structure. For example, by exerting a collision absorbing power, it is possible to give the occupant a sense of security and refreshment of the material of the outer surface.

In the first aspect, the vehicle interior structure further includes a lining portion that is disposed between the hollow structure body and the second light emitting portion and is capable of transmitting light emitted by the second light emitting portion. Also good.

  A general lining portion can be made transparent, and an outer surface portion is formed on the lining portion via a hollow structure, so that various light-ups can be provided inside the vehicle interior 150 of the lining portion.

  In the first aspect, the light source of the second light emitting unit may emit light of at least two colors in a switchable manner.

  By changing the color of the second light emitting unit according to, for example, the feeling of the occupant, the comfort of the occupant can be improved. It is also possible to give the passenger a dynamic visual effect.

  1st aspect WHEREIN: The said surface of the said outer surface part may be plain when the ultraviolet-ray is not irradiated to the said surface by a 1st light emission part.

  Since the predetermined pattern appears for the first time by the first light emitting unit, the degree of change in the interior impression is high, and the passenger's satisfaction is improved. In addition, for example, if the outer surface is regarded as a campus, passenger comfort is improved.

  Those skilled in the art will readily understand that the illustrated embodiments according to the present invention can be further modified without departing from the spirit of the present invention.

An explanatory view of the passenger compartment is shown. The application example of the interior structure for vehicles according to this invention is shown. The structural example of the vehicle interior structure according to this invention is shown. An example of the disassembled perspective view of the vehicle interior structure of FIG. 3 is shown. An example of the functional block diagram of the control system which controls the 1st light emission part and the 2nd light emission part is shown.

  The preferred embodiments described below are used to facilitate an understanding of the present invention. Accordingly, those skilled in the art should note that the present invention is not unduly limited by the embodiments described below.

  FIG. 1 is an explanatory view of a passenger compartment. A vehicle 200 such as an automobile includes a passenger compartment. In the example of FIG. 1, the passenger compartment includes, for example, a roof lining 110, a right front door running 120, a left front door running 121, a meter 180, and the like. 130, a windshield 140, and the like are provided. In other words, a vehicle compartment or a vehicle compartment space is defined by these members, and these members are exposed to the vehicle compartment. The interior of the passenger compartment can be constituted by these members. For example, the roof lining 110 as an interior member is made of resin, woven fabric, nonwoven fabric, or the like. The vehicle interior structure according to the present invention can be applied to interior members such as roof lining 110, door running 120, 121, instrument panel 130, seat 160 in FIG.

  FIG. 2 shows an application example of the vehicle interior structure according to the present invention. In the example of FIG. 2, the passenger compartment 150 of the vehicle 200 includes the roof lining 110 of FIG. 1 as a lining portion, and details of the characteristic structure of the roof lining 110 to which the vehicle interior structure according to the present invention is applied. As will be described later, the vehicle interior structure generally has a surface 11 inside the passenger compartment 150 on which a predetermined pattern visible by the ultraviolet light emitting section 5 (also referred to as a first light emitting section) is formed, A second light emitting unit is further provided between the surface 11 and the vehicle body 60, for example. When the vehicle interior structure is applied to the roof lining 110 of FIG. 1, the direction inside the passenger compartment 150 with reference to the outer surface portion of the vehicle interior structure is indicated by the symbol DR1.

  In the example of FIG. 2, the ultraviolet light emitting unit 5 is disposed on the headrest of the sheet 160, but the arrangement of the ultraviolet light emitting unit 5 can be changed. The arrangement of the ultraviolet light emitting unit 5 can be determined so that the ultraviolet light emitting unit 5 directly or indirectly irradiates the surface 11 with ultraviolet light according to the place where the vehicle interior structure is applied. The eye 171 of the occupant 170 faces the front of the vehicle 200, but even if the occupant 170 is facing forward, when the occupant 170 looks up or when the occupant 170 gets on, a part of the field of view of the occupant 170 All or part of the predetermined pattern on the surface 11 which appears by ultraviolet rays enters.

  FIG. 3 shows a configuration example of the vehicle interior structure according to the present invention. In the example of FIG. 3, a cross section of the vehicle interior structure 100 is shown. FIG. 4 shows an example of an exploded perspective view of the vehicle interior structure 100 of FIG. In the example of FIG. 4, the shape (or plan view) of the vehicle interior structure 100 has a square shape, but the actual shape of the vehicle interior structure 100 is, for example, the shape of all or part of the roof lining 110 of FIG. 1. Or can be changed according to its shape. Of course, for example, a vehicle interior structure 100 having a square shape as shown in FIG. 4 may be applied to a part of interior members such as roof lining 110.

  In the example of FIG. 3, black light inks 10a to 10i forming a predetermined pattern are printed on the surface 11 by, for example, an ink jet printer. The black light inks 10a to 10i contain a fluorescent material. For example, the fluorescent material is excited by irradiating the fluorescent material with ultraviolet light from an ultraviolet light emitting unit 5 that can be constituted by an ultraviolet LED element or an ultraviolet fluorescent lamp. Alternatively, the black light inks 10a to 10i emit light as a predetermined pattern. Light from the fluorescent material or the black light inks 10a to 10i forms visible light, and the visible light enters the eye 171 of the passenger 170, so that the passenger 170 recognizes a predetermined pattern. The fluorescent material or the black light inks 10a to 10i can be arranged so that the predetermined pattern represents a picture, a pattern, a pattern or the like.

  The fluorescent material preferably has no phosphorescent property. For example, after the ultraviolet light emitting unit 5 is turned off, the afterglow time during which the predetermined pattern can be recognized by the occupant 170 is preferably within several seconds, and more preferably Within 1 second. Further, the kind of fluorescent material or the number of emission colors may be one or plural. For example, when a picture, pattern, pattern, or the like is represented in color, the type of fluorescent material or the number of luminescent colors is preferably three or more of the three primary colors red, green, and blue.

  Further, the fluorescent material such as the black light inks 10a to 10i is preferably transparent when the ultraviolet light emitting unit 5 is not irradiated with ultraviolet rays, and the surface 11 or the base of the surface 11 is preferably plain. Since the predetermined pattern (transparent → light emission) appears for the first time by the ultraviolet light emitting unit 5, the degree of change in the interior impression is high, and the satisfaction of the occupant 170 is improved. Further, for example, the comfort of the occupant 170 is improved by assuming the plain surface 11 as a campus.

  In the example of FIG. 3, the outer skin 10 has a front surface 11 inside the passenger compartment 150 and a back surface 12 opposite to the inner side of the passenger compartment 150. In one example of the outer skin 10, preferably, the thickness of the outer skin 10 is 0.1 [mm], which is more than a general thickness of about 0.6 [mm] to 1.2 [mm]. It is very thin, preferably composed of tricot (polyester). The outer skin 10 faces the ultraviolet light emitting part 5, for example, so that a predetermined pattern (10 a to 10 i) is visible when the ultraviolet light emitting part 5 irradiates the surface 11 with ultraviolet rays. The vehicle interior structure 100 has a light source such as a yellow LED element 51 that is disposed in a direction opposite to the inside of the passenger compartment 150 (a direction opposite to the sign DR1) and is different from the ultraviolet light emitting unit 5 (first light emitting unit). A visible light emitting unit 50 (also referred to as a second light emitting unit) is provided. In the example of FIG. 3, the second light emitting unit 50 can be configured by, for example, a yellow LED element 51, for example, a blue LED element 52, and for example, an LED substrate 53. The light source of the second light emitting unit 50 may be configured with a visible light fluorescent lamp or the like instead of the visible light LED element. In addition, the type of light source or the number of emission colors of the second light emitting unit 50 is, for example, two colors of yellow and blue, but may be one of arbitrary colors such as yellow, and is three or more. May be.

  The second light emitting unit 50 including the yellow LED element 51, the blue LED element 52, and the like irradiates, for example, yellow light toward the back surface 12 of the outer skin 10 in the direction DR1 inside the passenger compartment 150. The outer skin 10 is formed so as to be transmissive to yellow light, and can be made of, for example, a transparent material, a translucent material, or the like. The outer skin 10 can also transmit visible light such as yellow light by reducing the thickness of the outer skin 10. A predetermined pattern such as a picture, a pattern, or a pattern can be visually recognized by the ultraviolet light emitting unit 5, and a yellow light source, for example, can be visually recognized through the outer skin 10 by the yellow LED element 51. Since the light source such as the yellow LED element 51 can be controlled independently, the light emission time of the yellow LED element 51 can be controlled, and thus the comfort of the passenger 170 can be improved. Note that warm colors such as yellow, red, and orange can give the occupant 170 a warm feeling, and the yellow LED element 51 may be changed to a warm color LED element other than yellow. By continuously lighting the yellow LED element 51, the occupant 170 can be satisfied with the warm color during the lighting time.

  In Patent Document 1, the light emission time of the pattern element 3A cannot be controlled, and when the passenger feels uncomfortable, the passenger's satisfaction may be reduced.

  In the example of FIG. 3, the vehicle interior structure 100 includes a structure having a plurality of hollows 21 disposed between the outer skin 10 and the second light emitting unit 50 (yellow LED element 51, blue LED element 52) ( The hollow structure) and the lining portion 30 are preferably provided, but these may not be provided. Although only the outer skin 10 can be referred to as the outer surface portion, the hollow structure is omitted, and for example, a combination of the outer skin 10 and the lining portion 30 can also be referred to as the outer surface portion. Alternatively, the thickness of the outer skin 10 may be increased and the lining portion 30 may be omitted.

  Since the light from the light source of the second light-emitting unit 50 reaches the outer skin 10 through the hollows 21 and 21 and the non-hollow part of the hollow structure, the second light-emitting unit 50 increases the density (hollow) of the light source such as color. 21, 21) A light (non-hollow part) can be expressed, and for example, an impression of light with transparency, soft light, or the like can be given to the occupant 170. In the example of FIG. 4, the hollows 21 and 21 form a honeycomb structure, but the hollows 21 and 21 (or non-hollow portions) are changed by changing the size (or area) and position of the hollows 21 and 21. As such, a predetermined pattern such as a picture, a pattern, or a pattern (different from the predetermined pattern formed by the black light inks 10a to 10i) may be configured.

  When the outer skin 10 and the hollow structure have elasticity, the elasticity of the outer skin 10 is emphasized by the elasticity of the hollow structure. In addition, a refreshing feeling can be given to the occupant 170.

  The lining portion 30 is a base material of the vehicle interior structure 100, for example, like a general lining portion such as the roof lining 110 of FIG. For example, the lining part 30 (base material) formed of resin or the like and having a certain degree of hardness is formed so as to be transmissive to the light irradiated by the second light emitting part 50. The outer skin 10 is formed on the lining portion 30 through the hollow structure, thereby providing various light-ups by the first light emitting portion 5 and the second light emitting portion 50 to the inside of the passenger compartment 150 of the lining portion 30. can do.

  In the example of FIG. 3, the vehicle interior structure 100 further includes a spacer 40 for fixing the LED board 53 to the lining portion 30, but when the LED elements 51 and 52 are thin, the LED board 53 is mounted on the vehicle body. The spacer 40 may be omitted, for example, when it is directly fixed to the 60.

  FIG. 5 shows an example of a functional block diagram of a control system that controls the first light emitting unit 5 and the second light emitting unit 50. In the example of FIG. 5, the control unit 300 is connected to, for example, a battery 310 (DC power supply), and the battery 310 can supply power to the control unit 300. The control unit 300 includes, for example, a constant voltage circuit, and can convert, for example, a 12V battery power supply voltage into a 5V logic power supply voltage, for example. The control unit 300 includes a logic circuit that can operate with a logic power supply voltage, for example, and turns on or off each of the first light emitting unit 5 and the second light emitting unit 50. Further, the control unit 300 includes, for example, a power supply circuit, and can start supplying power to each of the first light emitting unit 5 and the second light emitting unit 50 from the power supply circuit, and can continue or stop the supply. it can. The control unit 300 can be configured by an electronic control unit (ECU). Alternatively, the control unit 300 can be controlled by adopting the battery 310 as a power source for the first light emitting unit 5 and the second light emitting unit 50. Unit 300 may be configured with only a simple switch.

  The control unit 300 can turn on the first light emitting unit 5 (ultraviolet light emitting unit, black light) in accordance with an ON operation or an ON operation of the occupant 170 and irradiate the surface 11 of the outer skin 10 with ultraviolet rays. Moreover, the control part 300 can make the 1st light emission part 5 light-extinguish according to OFF operation or OFF operation | movement of the passenger | crew 170, and can stop irradiation of an ultraviolet-ray. Similarly, the control unit 300 can turn on the second light emitting unit 50 (visible light emitting unit) in accordance with the ON operation or ON operation of the occupant 170 and irradiate the back surface 12 of the outer skin 10 with visible light. . In addition, the control unit 300 can turn off the second light emitting unit 50 in accordance with the OFF operation or the OFF operation of the occupant 170 and stop the irradiation of visible light.

  When only one of the first light emitting unit 5 and the second light emitting unit 50 is lit, the OFF operation of the first light emitting unit 5 can be linked with the ON operation of the second light emitting unit 50. That is, when the first light emitting unit 5 is turned off by the OFF operation of the first light emitting unit 5, the second light emitting unit 50 can be turned on. Therefore, the outer skin 10 is formed so that the light emitted by the second light emitting unit 50 when the first light emitting unit 5 is not irradiated with ultraviolet rays can be transmitted in the direction DR1 inside the passenger compartment 150. Before switching from the first light emitting unit 5 to the second light emitting unit 50, the transmitted light from the second light emitting unit 50 is invisible, and the degree of change in the interior impression is high, and the passenger 170 is satisfied. Will improve.

  Similarly, the OFF operation of the second light emitting unit 50 can be linked with the ON operation of the first light emitting unit 5. That is, when the second light emitting unit 50 is turned off by the OFF operation of the second light emitting unit 50, the first light emitting unit 5 can be turned on. Therefore, the light emitted by the second light emitting unit 50 is blocked when the first light emitting unit 5 is irradiated with ultraviolet rays. Since the transmission of light from the light source of the second light emitting unit 50 through the outer skin 10 is blocked, the first light emitting unit 5 makes it possible to visually recognize the predetermined pattern more reliably.

  As described above, the control unit 300 can switch between the first light emitting unit 5 and the second light emitting unit 50. Further, when the second light emitting unit 50 has a plurality of light sources, the control unit 300 A plurality of light sources can be switched. When the light emitting unit 5 is turned off and the second light emitting unit 50 is turned on, the control unit 300 can turn on only one of the yellow LED element 51 and the blue LED element 52, for example.

  For example, when the warm color is set in the control unit 300, only the yellow LED element 51 can be turned on when the second light emitting unit 50 is turned on. Alternatively, for example, when cold color is set in the control unit 300, only the blue LED element 52 can be turned on when the second light emitting unit 50 is turned on. Note that the blue LED element 52 may be changed to a light blue or purple color LED element other than blue. The control unit 300 may be connected to the sensor 320. The sensor 320 may sense the temperature of the outside air or the like, or may analyze the facial expression of the occupant 170 to estimate and sense the mood of 170. That is, the control unit 300 may automatically set the warm color or the cold color according to the detection result or the estimation result of the sensor 320. In order to execute such a control example, the light source of the second light emitting unit 50 may emit light of each of at least two colors so as to be switchable by the control unit 300. The comfort of the occupant 170 can be improved by changing the color of the second light emitting unit 50 according to, for example, the feeling of the occupant 170. However, a warm color or a cold color may be manually set in the control unit 300 by the occupant 170 according to the preference of the occupant 170.

  For example, the control unit 300 can turn on the plurality of yellow LED elements 51 at the same time and turn off the plurality of blue LED elements 51 at the same time, but may control the individual LED elements 51 and 52 independently. . In other words, the LED substrate 53 is regarded as an LED display panel, and a predetermined pattern (different from the predetermined pattern formed by the black light inks 10a to 10i) is formed by turning on or off the individual LED elements 51 and 52. May be.
