[0003] [Patent Document 1] JP 2006-321336 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the vehicle door described in Patent Document 1, the decorative panel (decorative lighting device) and the multiple components (electrodes, light source, circuit board, case, etc.) constituting the switch device are arranged overlapping in the width direction (thickness direction) of the door, which increases the thickness of the vehicle interior part and therefore increases the thickness of the door. Therefore, there has been a demand for a vehicle interior part that is provided with a decorative lighting device and a switch device but has a reduced thickness.

[0005] The present invention has been made in consideration of the above problems, and its object is to provide a vehicle interior part and a vehicle door that are equipped with a decorative lighting device and a switch device while suppressing an increase in the thickness of the vehicle interior part. [Means for solving the problem]

[0006] The above problem is solved by the vehicle interior product of the present invention, which comprises a switch device for controlling an on-board device mounted in a vehicle, and a decorative panel that is translucent and has a pattern on its surface indicating an operating position, wherein the switch device has an electrode arranged at a position overlapping the decorative panel when the decorative panel is viewed from the front side, a control unit that detects changes in the electrode and controls the operation of the on-board device, and a light source that illuminates the position where the electrode is arranged or the vicinity of the position where the electrode is arranged from the back side of the decorative panel, and displays the pattern on the surface of the decorative panel, and the light source is arranged at a position that does not overlap the decorative panel when the decorative panel is viewed from the front side.

[0007] Since the light source that illuminates the decorative panel is positioned at a position that does not overlap with the decorative panel when viewed from the front side, the vehicle interior part can be equipped with a decorative lighting device and a switch device while preventing an increase in thickness, making it possible to make the vehicle interior part thinner.

[0008] In the above configuration, the light source may be disposed outside the outer periphery of the decorative panel. By arranging the light source outside the outer periphery of the decorative panel, the increase in thickness of the vehicle interior part is suppressed compared to when the light source is arranged in the thickness direction of the decorative panel, making it possible to make the vehicle interior part thinner.

[0009] In the above configuration, the light source may be disposed at a position overlapping the decorative panel when the decorative panel is viewed from above. By arranging the light source in a position that overlaps with the decorative panel when viewed from above, the increase in thickness is suppressed compared to when the light source is arranged in the thickness direction of the decorative panel, making it possible to make vehicle interior parts thinner.

[0010] In addition, in the above configuration, the vehicle interior part includes a base material having a light source mounting portion for mounting the light source and a shading portion attached to the rear surface of the decorative panel, and the light source mounting portion and the shading portion are preferably formed integrally with the base material. Since the light source attachment portion and the light blocking portion are formed integrally with the base material, the number of parts can be reduced.

[0011] In the above-mentioned configuration, the base material may be configured to fix the decorative panel. By forming the light source attachment portion and the light blocking portion integrally with the base material to which the decorative panel is fixed, the number of parts can be reduced.

[0012] In the above configuration, the control unit may be attached to the base material. By attaching the control unit to a base material, the base material can also be used as a mounting part for the control unit, thereby making it possible to reduce the number of parts.

[0013] In the above configuration, the control unit may be disposed on a rear surface of the light blocking unit. By disposing the control unit on the rear surface of the light blocking unit, the space on the rear surface side of the base material can be effectively utilized.

[0014] In addition, in the above configuration, the decorative panel has a planar portion, a wall portion extending from the planar portion toward the thickness direction of the decorative panel, and an engagement portion formed on the wall portion and engaging with the base material, and the light source is preferably positioned above the engagement portion of the decorative panel and on the surface side of the decorative panel in the thickness direction. By arranging the light source above the engagement portion of the decorative panel and on the front surface side in the thickness direction of the decorative panel, it is possible to prevent light from the light source from interfering with the engagement portion.

[0015] In the above configuration, the light source may be disposed at a position overlapping with the wall portion of the decorative panel when the decorative panel is viewed from above. Since the light source overlaps with the wall of the decorative panel, when the light source emits light, the light can be transmitted directly to the decorative panel.

[0016] In addition, a vehicle door may include a vehicle interior accessory having the above-described configuration, an openable and closable window member, a door trim arranged below the window member, and an armrest provided on the door trim and capable of supporting the arms of a seated occupant, wherein the vehicle interior accessory is provided on the door trim, and the decorative panel is positioned between an upper end of the door trim and an upper end of the armrest. Since the decorative panel is disposed above the armrest on which the arms are expected to be placed, the decorative panel is easily visible when operating in-vehicle equipment using a switch device.

[0017] Furthermore, in the vehicle door of the above configuration, the door trim comprises an upper member positioned below the window member, a lower member positioned below the armrest, and a middle member positioned below the upper member and above the armrest, and the surface of the decorative panel is positioned below the lower end of the upper member and above the upper end of the armrest. The part of the decorative panel that is visible to people inside the vehicle is positioned below the upper end of the upper member that receives light from the window and above the upper end of the armrest where one is expected to rest their arms, so that the light emitted by the decorative panel is easily visible when operating in-vehicle equipment using a switch device. Effect of the Invention

[0018] According to the vehicle interior accessory of the present invention, the light source that illuminates the decorative panel is positioned at a position that does not overlap with the decorative panel when viewed from the front side. This makes it possible to provide a decorative lighting device and a switch device while suppressing an increase in the thickness of the vehicle interior accessory, thereby making it possible to make the vehicle interior accessory thinner. In addition, by arranging the light source outside the outer periphery of the decorative panel, the increase in thickness of the vehicle interior part is suppressed compared to when the light source is arranged in the thickness direction of the decorative panel, making it possible to make the vehicle interior part thinner. In addition, by arranging the light source in a position that overlaps with the decorative panel when viewed from above, the increase in thickness is suppressed compared to when the light source is arranged in the thickness direction of the decorative panel, making it possible to make vehicle interior parts thinner. Furthermore, since the light source attachment portion and the light blocking portion are integrally formed, the number of parts can be reduced. Furthermore, by forming the light source attachment portion and the light blocking portion integrally with the base material to which the decorative panel is fixed, the number of parts can be reduced. Furthermore, by attaching the control unit to the base material, the base material can also be used as an attachment part for the control unit, thereby reducing the number of parts. Furthermore, by disposing the control section on the rear surface of the light blocking section, the space on the rear surface side of the base material can be effectively utilized. Furthermore, by arranging the light source above the engagement portion of the decorative panel and on the front surface side in the thickness direction of the decorative panel, it is possible to prevent light from the light source from interfering with the engagement portion. In addition, since the light source overlaps with the wall portion of the decorative panel, when the light source emits light, the light can be transmitted directly to the decorative panel. In addition, since the decorative panel is disposed above the armrest on which the arms are expected to be placed, the decorative panel is easily visible when operating the in-vehicle equipment using the switch device. In addition, the part of the decorative panel that is visible to people inside the vehicle is positioned below the top end of the upper member that receives light from the window and above the top end of the armrest where one is expected to rest their arms, so that the light emitted by the decorative panel is easily visible when operating in-vehicle equipment using a switch device.

[0022] In the following description, the traveling direction of a vehicle (not shown) in which the vehicle door D1 is provided is the forward direction, and the opposite side is the rearward direction, as shown by the arrow in Fig. 1. That is, in the following description, the "front-rear direction" refers to the front-rear direction when a passenger is seated. The inside of the vehicle (hereinafter also simply referred to as the inside) means the vehicle compartment side (the interior side of the vehicle), and the outside of the vehicle (hereinafter also simply referred to as the outside) means the outside of the vehicle. The width direction or thickness direction of the vehicle door D1 means the width direction of the vehicle door D1 when the vehicle is viewed from the front or rear, and means the direction from the inside to the outside of the vehicle, or the direction from the outside to the inside. In the following description, the upper side (lower side) means the upper side (lower side) when the vehicle interior part 10 and the vehicle door D1 are assembled to the vehicle. The "vertical direction" means the height direction of the vehicle and the vehicle door D1, and coincides with the vertical direction when the vehicle door D1 is viewed from the side.

[0023] The configuration of the vehicle interior part 10 according to this embodiment will be described below. In describing the vehicle interior part 10, first, the overall configuration of a vehicle door D1 and a door trim 1 to which the vehicle interior part 10 is attached will be outlined with reference to FIG.

[0024] <Overall configuration of vehicle door D1> The vehicle door D1 is a rear door provided in a vehicle, and includes a window member 2 that can be opened and closed by a window glass in a door frame F1, and a door trim 1 that is disposed below the window member 2. The door trim 1 is a member that is provided on the passenger compartment side of the vehicle door D1 that is supported on the vehicle so as to be openable and closable, for the purpose of interior decoration, etc. The door trim 1 is provided with an armrest 6 that can support the arms of an occupant seated in a vehicle seat. The vehicle interior part 10 is provided on the door trim 1, and the decorative panel 12 of the vehicle interior part 10 is disposed between an upper end 1a of the door trim 1 and an upper end 6a of the armrest 6. More specifically, the door trim 1 has an upper member 3 that is disposed below the window member 2 and disposed above the door trim 1, and a lower member 5 that is disposed below the armrest 6 and disposed below the door trim 1. The door trim 1 also has a middle member 4 that is disposed below the upper member 3 and above the armrest 6, and a surface 12a of a decorative panel 12 of a vehicle interior part 10 is disposed below a lower end portion 3b of the upper member 3 and above an upper end portion 6a of the armrest 6. The door trim 1 is made of a hard resin plate, but the material is not limited to resin and may be, for example, metal.

[0025] <Configuration of vehicle interior part 10> The vehicle interior part 10 will be described with reference to FIGS. As described above, the vehicle interior accessory 10 of this embodiment is provided on the door trim 1 and includes the switch device 13 for controlling the in-vehicle devices installed in the vehicle. The in-vehicle devices controlled by the switch device 13 include, for example, a reclining device for adjusting the seat angle, a position adjustment device for adjusting the position of the seat relative to the vehicle floor, a seat heater built into the seat, a blower, a massage device for the vehicle seat, an air conditioner for conditioning the interior of the vehicle, an in-vehicle window, a music player, etc. The switch device 13 is provided with a plurality of switches for operating the in-vehicle devices.

[0026] The vehicle interior accessory 10 also has a translucent decorative panel 12. A pattern indicating the location (operation position) of the switch of the switch device 13 is drawn on a surface 12a of the decorative panel 12. For example, as shown in Fig. 5, an icon indicating the control content of the switch device 13 is drawn as a pattern 33 on the surface 12a. The pattern 33 drawn on the surface 12a of the decorative panel 12 also indicates the position of the electrode 14.

[0027] The switch device 13 is a capacitive touch panel, and the electrodes 14 that function as the switches of the switch device 13 are arranged at predetermined positions that overlap the decorative panel 12 when the decorative panel 12 is viewed from the front surface 12a. In particular, the electrodes 14 of the switch device 13 are arranged to correspond to the positions of the patterns 33 of the decorative panel 12.

[0028] The vehicle interior part 10 has a detection circuit 17 that controls the operation of an in-vehicle device. The detection circuit 17 is, for example, an ECU (Electronic Control Unit) and functions as a control unit. The detection circuit 17 is connected to the electrode 14 of the switch device 13 by a flat cable 14a. The detection circuit 17 constantly monitors the capacitance of the electrode 14, and when it detects a change in the capacitance of the electrode 14, it determines that the switch is turned on and instructs the connected in-vehicle device to operate according to the state of the turned-on switch. The electrode 14 and the flat cable 14a are connected by a flat cable connection part 14b that extends from the upper end of the electrode 14 to the back side in the thickness direction as shown in FIG. 3.

[0029] The vehicle interior accessory 10 has a light source unit 30A (an example of a light source) disposed at a position not overlapping with the decorative panel 12 when viewed from the front surface 12a side of the decorative panel 12, i.e., when viewed in the direction of arrow A in Fig. 2. The light source unit 30A is disposed outside the outer periphery of the decorative panel 12. Also, the light source unit 30A is disposed at a position overlapping with the decorative panel 12 when viewed from above. As a result, light emitted from the light source unit 30A passes through the interior of the decorative panel 12, which is a transparent base material, and illuminates the position where the electrode 14 is disposed or the vicinity of that position from the rear surface 12b side of the decorative panel 12. 2 and 3, the rear surface 12b of the decorative panel 12 of this embodiment is formed in a sawtooth shape, and refracts light that enters the decorative panel 12 from above toward the front surface 12a. Therefore, even if the light source unit 30A is disposed above the decorative panel 12, it can sufficiently illuminate the front surface 12a of the decorative panel 12, and the pattern 33 can be displayed on the front surface 12a of the decorative panel 12.

[0030] If the light source unit 30A is conventionally disposed on the back side of the decorative panel 12, the thickness of the vehicle interior accessory 10 increases by the thickness of the light source unit 30A. If the light source unit 30A is disposed in a position that does not overlap with the decorative panel 12 when viewed from the front side, as in the present embodiment, an increase in the thickness of the vehicle interior accessory 10 is suppressed, and the vehicle interior accessory 10 can be made thinner.

[0031] In this embodiment, the light source unit 30A is positioned above the decorative panel 12, but the position of the light source unit 30A is not limited to this, and the light source unit 30A may be positioned in front of, behind, or below the decorative panel 12 as long as light can enter the decorative panel 12.

[0032] The vehicle interior part 10 of this embodiment has a base material 11 having a light source attachment portion 21 for attaching the light source unit 30A and a light shielding portion 16 arranged on the back surface 12b side of the decorative panel 12, as shown in FIG. 2. The light source attachment portion 21 and the light shielding portion 16 are integrally formed with the base material 11. The base material 11 also fixes the decorative panel 12. A detection circuit 17 is attached to the base material 11, and the detection circuit 17 is arranged on the back surface of the light shielding portion 16 of the base material 11, as shown in FIG. 2. The detection circuit 17 and the light source unit 30A are connected to a power source of the vehicle by a harness 20. As shown in FIG. 2, the base material 11 is fixed to the upper member 3 and the middle member 4 by fixing portions 18 at the upper and lower ends.

[0033] The decorative panel 12 of the vehicle interior part 10 has a flat surface 12c that faces the interior of the vehicle, and a wall portion 12d that extends from the flat surface toward the rear surface side of the decorative panel 12 in the thickness direction. An engagement portion 12e that is formed in a hook shape and engages with the base material 11 is provided at the tip of the wall portion 12d. A through hole 11c is formed in the base material 11 at a position corresponding to the wall portion 12d. The decorative panel 12 is fixed to the base material 11 by inserting the wall portion 12d of the decorative panel 12 into the through hole 11c of the base material 11 and hooking the engagement portion 12e at the tip.

[0034] 2, the light source unit 30A is disposed above the engagement portion 12e of the decorative panel 12 and on the surface 12a side in the thickness direction of the decorative panel 12. In other words, the light source unit 30A is disposed at a position overlapping with the wall portion 12d of the decorative panel 12 when the decorative panel 12 is viewed from above (in the direction of arrow A in FIG. 2).

[0035] As described above, electrodes serving as touch switches are arranged on the surface 12a of the decorative panel 12, and a decorative film 15 is attached to the surface side. The decorative film 15 is subjected to a coating (surface treatment). In the vehicle interior accessory 10 of this embodiment, a pattern 33 indicating the location of the switch is printed on the decorative film 15. The pattern 33 may be printed directly on the front surface 12a of the decorative panel 12, or may be attached as a separate piece from the decorative panel 12 so that the imprint can be seen through the back surface 12b of the decorative panel 12.

[0036] When the vehicle interior part 10 is not used as a switch device, it functions as a decorative part (interior part) for improving the design of the door. Therefore, the surface 12a of the decorative panel 12 exposed to the inside of the vehicle is colored metallic. Note that the surface 12a is not limited to a metallic color, and may be, for example, a wood grain or carbon pattern.

[0037] The light source unit 30A that illuminates the decorative panel 12 of the vehicle interior part 10 will be described with reference to FIG. The light source unit 30A includes a rod-shaped light guide 32 and a light emitting section 31 connected to one end of the light guide 32. The light guide 32 emits light from a light emitting surface 32a formed as a cylindrical surface having a linear central axis. The light source attachment section 21 holds the light guide 32 of the light source unit 30A to fix the light source unit 30A.

[0038] As shown in Fig. 4, a flat surface 32b is formed on the upper surface of the light-emitting surface 31a, and protrusions 32c are formed on the flat surface 32b, arranged in the longitudinal direction of the light guide 32 and extending in a direction perpendicular to the light intrusion direction (arrow B direction). The protrusions 32c are arranged at a constant pitch P over the entire longitudinal area. As shown in Fig. 5, the protrusions 32c are formed in a triangular shape having a ridgeline on the rear side perpendicular to the light intrusion direction. The width of the protrusions 32c in the direction perpendicular to the light intrusion direction (arrow B direction) is formed to increase with increasing distance from the light-emitting section 31.

[0039] When the light emitting portion 31 emits light, the light travels through the light guide 32 in the linear direction (longitudinal direction) of the light guide 32. The light is diffusely reflected by the convex portions 32c formed on the upper surface, and refracted in a direction perpendicular to the linear direction of the light guide 32. The refracted light is irradiated downward from the light emitting surface 32a. The irradiated light enters the decorative panel 12, is refracted by the rear surface 12b of the decorative panel 12, and is emitted from the front surface 12a of the decorative panel 12 into the vehicle cabin. In this way, the pattern 33 provided on the front surface 12a of the decorative panel 12 of the vehicle interior part 10 is illuminated.

[0040] 1 and 2, the vehicle interior part 10 of this embodiment is provided with a light source unit 30B below the decorative panel 12. The light source unit 30B is mainly for illuminating the surface of the central member 4 of the door trim 1, but the light emitted from the light source unit 30B also illuminates the decorative panel 12 of the vehicle interior part 10 from below. By illuminating the decorative panel 12 from above and below, the decorative panel 12 can be illuminated evenly.

[0041] Next, a vehicle interior accessory 110, which is a modified example of the vehicle interior accessory 10, will be described with reference to Figures 6 and 7. The vehicle interior accessory 110 includes a switch device that controls on-board equipment mounted on a vehicle, similar to the vehicle interior accessory 10 shown in Figure 2, but the positional relationship between the decorative panel 112 and the electrode 114 of the switch device 113 is different. The light source units 30A and 30B, the base material 11, the light blocking portion 16, the detection circuit 17, etc. are similar to those of the vehicle interior accessory 10 shown in Figure 2, and therefore detailed description thereof will be omitted.

[0042] 6, the back surface 112b side of the decorative panel 112 of the vehicle interior part 110 is formed flat, and an electrode 114 of a switch device 113 is disposed on the back surface 112b side. Light emitted from the light source unit 30A enters the decorative panel 112 from the upper end thereof and is diffused to illuminate the front surface 112a.

[0043] By arranging the electrode 114 serving as a touch switch on the back surface 112b side of the decorative panel 112, the electrode 114 does not block the light passing through the front surface 112a of the decorative panel 112. Therefore, the light can be made brighter. A decorative film 115 is directly disposed and coated on the surface 112a side of the decorative panel 112. A pattern 33 is printed on the surface 112a of the decorative panel 112, and the pattern 33 appears when the surface 112a of the decorative panel 112 is illuminated.

[0044] The electrode 114 and the detection circuit 17 are connected by a flat cable 14a. As shown in Fig. 6 and Fig. 7, since the electrode 114 is disposed on the back surface 112b side of the decorative panel 112, the flat cable connection portion 114b between the electrode 114 and the flat cable 114a does not cross the upper end portion of the decorative panel 112. The light source unit 30A is located above the decorative panel 112, and the light emitted from the light source unit 30A enters the upper end portion of the decorative panel 112, but since the flat cable connection portion 114b does not cross, the light emitted from the light source unit 30A is not blocked, and the decorative panel 112 can be illuminated evenly.

[0045] 3, the decorative panel 112 has a flat portion 112c that is exposed toward the interior of the vehicle, and a wall portion 112d that extends from the flat portion 112c toward the rear surface side in the thickness direction of the decorative panel 112. An engagement portion 112e that is formed in a hook shape and engages with the base material 11 is provided at the tip of the wall portion 112d. A through hole 11c is formed in the base material 11 at a position corresponding to the wall portion 112d. The wall portion 112d of the decorative panel 112 is inserted into the through hole 11c of the base material 11, and the engagement portion 112e at the tip is hooked, whereby the decorative panel 112 is fixed to the base material 11.

[0046] The vehicle interior parts 10, 110 and the vehicle doors D1, D2 equipped with the vehicle interior parts 10, 110 according to the embodiments of the present invention have been described above with reference to Figs. 1 to 7. In this embodiment, a capacitance type electrode is used as the electrode 14 of the switch device 13, which is a touch switch, but the electrode 14 is not limited to the capacitance type and may be a pressure-sensitive electrode 14. When the electrode 14 is a capacitance type, the detection circuit 17 detects a change in capacitance, but when the electrode 14 is a pressure-sensitive type, the detection circuit 17 detects a change in the contact state of the electrode 14. In addition, the light source unit 30A, which uses a rod-shaped light guide to diffuse light from the light-emitting section, is used as the light source. However, the light source is not limited to a configuration such as the light source unit 30A, and for example, multiple LEDs may be arranged in a straight line above the decorative panel 112 to illuminate the decorative panel 12.

[0047] <<Other embodiments>> Hereinafter, configurations of a vehicle interior part and a vehicle door including the vehicle interior part according to another embodiment will be described with reference to the drawings.

[0048] Other embodiments relate to a vehicle interior part and a vehicle door, and relate to a vehicle interior part and a vehicle door that are provided with a heating device and a lighting device.

[0049] International Publication No. 2019 / 064359 discloses a vehicle interior product having a heater function. Specifically, a planar heater is disposed above an armrest provided on the door trim of a vehicle door and located in a position that is easy for a seated occupant to touch. This planar heater is disposed on a middle member disposed above the armrest and on the outer side in the vehicle width direction, and is configured by covering a nonwoven fabric constituting a surface layer of the middle member with a conductive heating wire. When electricity is passed through this heating wire, the heating wire generates heat, and when an occupant supports his / her arms on the armrest, the arms of the occupant touching the middle member can be warmed.

[0050] Incidentally, in the planar heater in WO 2019 / 064359, in order for a seated occupant to know the temperature, the occupant had to visually check the state of the switch that turns on the planar heater or directly touch the planar heater. In addition, even if the planar heater switch is in the ON state, there is a time lag until the heating wire itself heats up, or until the heating wire warms the surface layer of the armrest, so the occupant could only feel the temperature by actually touching it. Therefore, it was desired that the occupant could perceive the temperature of the planar heater without actually touching it. In addition, there was a demand for a technology that would allow the occupant to feel the temperature higher than if the occupant actually touched it.

[0051] The other embodiments of vehicle interior accessories described below were invented in consideration of the above-mentioned problems, for example, and their purpose is to provide a vehicle interior accessory that allows occupants to sense the state of a heating device without actually touching the heating device.

[0052] The above problem is solved in another embodiment of a vehicle interior accessory, which includes a heating device that dissipates heat into the vehicle cabin to warm occupants, a detection device that detects the state of the heating device, a display device provided in the vehicle cabin, and a control device that controls the display of the display device, wherein the control device changes the display of the display device based on the state of the heating device detected by the detection device.

[0053] By changing the display on the display device based on the state of the heating device, the state of the heating device can be visualized by the display device, and the passenger can perceive the state of the heating device without actually touching it. Also, by making the state of the heating device appear to be high temperature on the display device, the passenger can feel the temperature of the heating device higher than the actual temperature.

[0054] In addition, in the above configuration, the control device may set a state in which the heating device is in any state as a reference state, and when the heating device is in the reference state, display the display device in an initial display mode, and when the state of the heating device detected by the detection device is a first state that satisfies a first condition, display the display device in a first display mode different from the initial display mode. By visualizing each state of the heating device, the occupant can recognize the state of the heating device.

[0055] In addition, in the above configuration, when the state of the heating device detected by the detection device is a second state that satisfies a second condition different from the first condition, the control device may display the display device in a second display mode different from the first display mode. By visualizing each state of the heating device, the occupant can recognize the state of the heating device.

[0056] In the above configuration, the display device may be a lighting device provided inside the vehicle cabin, and the control device may control the color of light emitted by the lighting device and / or the intensity of the amount of light emitted by the lighting device. Since the state of the heating device is displayed by the lighting device, the information can be obtained without focusing, and therefore the visibility of the heating device state display can be improved.

[0057] Furthermore, in the above configuration, the control device may cause the lighting device to emit light in the initial mode when the thermal device is in the reference state, cause the lighting device to emit light in a first light-emitting mode when the state of the thermal device detected by the detection device is a first state that satisfies the first condition, and cause the lighting device to emit light in a second light-emitting mode different from the first light-emitting mode when the state of the thermal device detected by the detection device is a second state that satisfies the second condition. Since the state of the heating device is displayed by the lighting device, the information can be obtained without focusing, and therefore the visibility of the heating device state display can be improved.

[0058] In addition, in the above configuration, the control device controls the display mode of the display device to change based on the temperature of the heating device detected by the detection device, and the reference state is a state in which the temperature of the heating device is from an arbitrary reference temperature to a first set temperature, the first state is a state in which the temperature of the heating device is from the first set temperature to a second set temperature that is set as a temperature higher than the first set temperature, and the second state is a state in which the temperature is equal to or higher than the second set temperature. The temperature of the heating device can be displayed on the display device, making it easy to recognize whether the device is sufficiently warmed or not.

[0059] In addition, in the above configuration, the control device may further have an RGB adjustment unit that changes the light emission mode of the lighting device by individually adjusting the R value, G value, and B value of RGB values ​​that indicate color information, and the R value indicating red color of the first light emission mode of the lighting device may be set higher than the R value of the initial light emission mode, and the R value of the second light emission mode may be set higher than the R value of the first light emission mode. By adjusting the RGB values ​​to make the red color darker, the light emission pattern changes from cool to warm colors, making it easier to recognize the rise in temperature and making the temperature feel higher than it actually is when the passengers touch it.

[0060] In addition, in the above configuration, the display device is a lighting device provided inside the vehicle cabin, and the control device further includes an RGB adjustment unit that controls the light emission color and / or the intensity of the light emission of the lighting device, and changes the light emission mode of the lighting device by individually adjusting the R value, G value, and B value of the RGB values ​​that indicate color information, a state switching unit that can switch between an ON state in which electricity is supplied to the heating device and an OFF state in which electricity is not supplied, and a temperature determination unit that determines the temperature of the heating device when the vehicle is switched from a non-driving state to a driving state and the heating device has never been in the ON state, and when the temperature determination unit determines that the temperature of the heating device is higher than the reference temperature, the B value, which indicates blue, is set higher than the R value and the G value. By adjusting mainly the B value, which represents the blue color among the RGB values, it becomes easier to associate a feeling of coolness in a temperature environment where heating devices are not required, such as in summer.

[0061] In addition, in the above configuration, the control device may further have a state switching unit that can switch the heating device between an ON state in which current is applied to it and an OFF state in which current is not applied, and an elapsed time determination unit that determines whether a predetermined time has elapsed when the heating device is switched from the ON state to the OFF state, and when the elapsed time determination unit determines that the predetermined time has elapsed, the light emission state of the lighting device may be changed to a third light emission state. When a predetermined time has elapsed since the power supply to the heating device was turned off, it is possible to easily visually confirm that the heating device has cooled down.

[0062] In addition, in the above configuration, the control device may further have an RGB adjustment unit that changes the light emission mode of the lighting device by individually adjusting the R value, G value, and B value of RGB values ​​that indicate color information, and the third light emission mode may be a mode in which the B value, which indicates blue color among the light emission modes of the lighting device, is set higher than the R value and the G value. When a specified time has passed since the power to the heating device was turned off, the RGB values ​​are adjusted to make the blue color darker, making it easier to visually see that the heating device has cooled down.

[0063] In the above configuration, the display device may be disposed in the vicinity of the heating device. Since the display device is disposed near the heating device, it is easy to associate the display on the display device with the temperature of the heating device.

[0064] In addition, a vehicle door may include a vehicle interior part having the above-described configuration, an openable and closable window member, a door trim arranged below the window member, and an armrest provided on the door trim and capable of supporting the arms of a seated occupant, and the display device may be arranged between an upper end of the door trim and an upper end of the armrest. Since the display device is disposed at a position higher than the arm rest on which the arms are placed and lower than the window member, the display device can be viewed from a position that is less affected by the brightness outside.

[0065] In addition, in the above vehicle door, the door trim comprises an upper member arranged below the window member, a lower member arranged below the armrest, and a middle member arranged below the upper member and above the armrest, and the heating device is arranged in the middle member at the same position as the armrest at least in the fore-and-aft direction, and the display device is arranged above the heating device. It is assumed that a person's arm will be placed on the armrest in contact with the heating device. By locating the display device above the armrest, the passenger can feel the warmth of the heating device at a highly visible position even when the passenger places their arm on the heating device.

[0066] Hereinafter, configurations of a vehicle interior part and a vehicle door including the same according to another embodiment will be described with reference to the drawings.

[0068] The following describes a configuration of a vehicle interior part 210 according to another embodiment. In describing the vehicle interior part 210, first, the overall configuration of a vehicle door D2 and a door trim 201 to which the vehicle interior part 210 is attached will be outlined with reference to FIG.

[0069] <Overall configuration of vehicle door D2> The vehicle door D2 is a front door provided in a vehicle, and includes a window member 202 that can be opened and closed by a window glass in a door frame F2, and a door trim 201 that is disposed below the window member 202. The door trim 201 is a member that is provided on the passenger compartment side of the vehicle door D2 that is supported on the vehicle so as to be openable and closable, for the purpose of interior decoration, etc. The door trim 201 is provided with an armrest 206 that can support the arms of an occupant seated in a vehicle seat. The vehicle interior part 210 is provided on the door trim 201, and a decorative panel 213a that is used as a display device of the vehicle interior part 210 is disposed between an upper end 201a of the door trim 201 and an upper end 206a of the armrest 206. More specifically, the door trim 201 has an upper member 203 that is disposed below the window member 202 and disposed at the upper part of the door trim 201, and a lower member 205 that is disposed below the armrest 206 and disposed at the lower part of the door trim 201. The door trim 201 also has a middle member 204 that is disposed below the upper member 203 and above the arm rest 206 .

[0070] 10, a vehicle interior part 210 according to another embodiment includes, as a hardware configuration, a door heater 211 which is a heating device, a thermistor 212 which is a detection device, a lighting device 213 which is a display device, an operation switch 214 which is an input device, and an ECU 215 which is a control device. The door heater 211, thermistor 212, lighting device 213, operation switch 214, and ECU 215 are connected by a harness or a connection cable, and the door heater 211 and lighting device 213 are controlled by ECU 215.

[0071] The door heater 211 is a heating device that radiates heat into the vehicle interior to warm the occupant, and is made of a heater base fabric 211b including a heating wire 211a. The door heater 211 is disposed in a central member 204 and an armrest 206 of the door trim 201, as shown in Figs. 8 and 9. The door heater 211 is disposed in the central member 204 at the same position as the armrest 206 in at least the front-rear direction of the door. As shown in Fig. 9, a base material 226 of the armrest 206 is provided on the surface of the door trim 1 facing the vehicle interior, and a heat shielding material 221 that shields heat from the door heater 211 is disposed on the surface of the base material 226 facing the vehicle interior. The heat shielding material 221 may be a reflective material that reflects heat. A heater base fabric 211b including a heating wire 211a as a door heater 211 is provided on the vehicle interior surface of the heat shield 221, and a slab 222 and a skin material 223 are further arranged in this order on the vehicle interior surface of the door heater 211.

[0072] A thermistor 212 for detecting the temperature of the door heater 211 is provided near the door heater 211. The thermistor 212 is connected to the ECU 215 by a harness 212a, and temperature information detected by the thermistor 212 is transmitted to the ECU 215.

[0073] The lighting device 213 is composed of a transparent decorative panel 213a and a light source unit 213b arranged above the decorative panel 213a. The light source unit 213b is composed of a light emitter and a thin rod-shaped light guide connected to the light emitter, similar to the light source unit 30A shown in FIG. 4. The back surface of the decorative panel 213a has a sawtooth cross section as shown in FIG. 9. The light emitted from the light guide of the light source unit 213b enters the upper end of the decorative panel 213a and is refracted by the back surface of the decorative panel 213a, causing the surface of the decorative panel 213a to shine.

[0074] The lighting device 213 is provided in the vehicle cabin and controlled by the ECU 215, and can change its light emission mode (display mode). The lighting device 213 can change the color of light emitted by individually adjusting the R value indicating red, the G value indicating green, and the B value indicating blue among the RGB values ​​indicating color information. More specifically, the color of light emitted by the light emitter included in the light source unit 213b of the lighting device 213 is changed, thereby changing the color of light emitted by the surface of the decorative panel 213a.

[0075] The ECU 215 is a control device, and includes a processor 215a (control unit), a memory 215b (storage unit), and an input interface 215c. The processor 41 is a central processing unit that executes various arithmetic processing based on programs and data stored in the memory 42 and signals received from each device connected via the input interface 215c, and controls the lighting device 213 and the door heater 211. The memory 42 is, for example, a semiconductor memory, and in addition to storing various programs and data, it also functions as a work memory for the processor 41. In another embodiment, it stores the light emission mode, conditions, set temperature, etc. to be displayed by the lighting device 213, which will be described later. The input interface 215c is connected to the door heater 211, thermistor 212, lighting device 213, and operation switch 214, and communicates with each device.

[0076] In a vehicle interior part 210 of another embodiment, a thermistor 212 detects the temperature of a door heater 211, and the thermistor 212 transmits the detected temperature information to an ECU 215. The ECU 215 changes the display of the lighting device 213 based on the received temperature information, in other words, the state of the door heater 211. For example, when the temperature of the door heater 211 becomes high, the ECU 215 changes the light emission color of the lighting device 213 from yellow to orange, or from orange to red, accordingly.

[0077] More specifically, the emission color changing process performed by the ECU 215 will be described with reference to FIGS. Three modes (initial light-emitting mode, first light-emitting mode, second light-emitting mode) in which the illumination device 213 emits light are set. The initial light-emitting mode, the first light-emitting mode, and the second light-emitting mode are set so that the light-emitting modes are different. Specifically, how the illumination device 213 emits light in each mode is set. For example, the illumination device 213 is set to emit yellow light in the initial light-emitting mode, orange light in the first light-emitting mode, and red light in the second light-emitting mode. The initial light-emitting mode, the first light-emitting mode, and the second light-emitting mode are examples of the initial display mode, the first display mode, and the second display mode of the present invention, and in addition to changing the light-emitting color, the luminance of the illumination device 213 may be changed, or the temperature state may be displayed numerically.

[0078] Also, a first temperature is set as a threshold value for a condition (first condition) for changing from the initial light emission mode to the first light emission mode. Also, a second temperature is set as a threshold value for a condition (second condition) for changing to the second light emission mode. The first and second temperatures as threshold values ​​are stored in advance in the memory of ECU 215. Also, the first and second temperatures may be changed by the occupant using operation switch 214 or the like.

[0079] An occupant uses the operation switch 214 to turn on the power supply of the door heater 211 (S101). The thermistor 212 detects the temperature of the door heater 211 (S102). Immediately after the power supply is turned on, the heating wire 211a of the door heater 211 is not yet warmed up (reference state). It takes time for the heating wire 211a to be sufficiently warmed up (there is a time lag). The thermistor 212 detects the temperature in the not yet warmed up state and transmits the temperature information to the ECU 215 (S102). The ECU 215 determines whether the temperature (temperature information) of the door heater 211 is equal to or higher than the first temperature (S103). When the ECU 215 determines that the temperature of the door heater 211 is not equal to or higher than the first temperature (No in S103), the ECU 215 displays the lighting device 213 in an initial display mode, for example, causes the lighting device 213 to emit light in yellow. The thermistor continues to detect the temperature of the door heater, and the ECU 215 determines the temperature of the door heater 211. When the ECU 215 determines that the temperature of the door heater 211 is equal to or higher than the first temperature (Yes in S103), the ECU 215 causes the lighting device 213 to display in the first display mode, for example, to emit light in orange.

[0080] The thermistor 212 continues to detect the temperature of the door heater 211, and transmits the detected temperature information to the ECU 215 (S106). The ECU 215 determines whether the temperature (temperature information) of the door heater 211 is equal to or higher than the second temperature (S107). When the ECU 215 determines that the temperature of the door heater 211 is not equal to or higher than the second set temperature (No in S107), the ECU 215 displays the lighting device 213 in the first display mode. The thermistor 212 continues to detect the temperature of the door heater 211, and the ECU 215 determines the temperature of the door heater 211. When the ECU 215 determines that the temperature of the door heater 211 is equal to or higher than the second set temperature (Yes in S107), the ECU 215 displays the lighting device 213 in the second display mode, for example, causes it to emit light in red.

[0081] As shown in FIG. 12, when a sufficient amount of time has passed since the power supply of the door heater 211 was turned on and the temperature reaches or exceeds the second temperature, the temperature does not rise beyond a certain level. Thereafter, when the power supply to the door heater 211 is turned off (S109), the lighting device 213 may be turned off.

[0082] In the above example, the initial light-emitting state is set to yellow, the first light-emitting state to orange, and the second light-emitting state to red, but this is merely an example and is not limited to this combination. If the light source unit of the lighting device is capable of individually adjusting the R, G, and B values ​​of the RGB values, the ECU 215 has an RGB adjustment unit that changes the light-emitting state of the lighting device 213, so that the R value indicating red is set high. Specifically, the R value of the second light-emitting state is set higher than the R value of the first light-emitting state, and the R value of the third light-emitting state is set higher than the R value of the second light-emitting state.

[0083] When the environmental temperature is high, such as the interior space of a parked car in summer, the temperature of door heater 211 detected by thermistor 212 may be high even if door heater 211 is not in use. In such a case, a cool feeling may be created by setting the emitted color of lighting device 213 to a cool color. More specifically, when the door heater is OFF and the temperature detected by thermistor 212 exceeds a predetermined fourth temperature, the B value indicating blue among the emitted colors emitted by the light source unit is set to be higher than the R value and the G value.

[0084] The above process will be described with reference to FIG. 13. First, it is confirmed whether the power supply of the door heater 211 is ON (S201). If the door heater 211 is ON (Yes in S201), the process S100 for changing the light emission color of the lighting device 213 shown in FIG. 11 is performed. If the door heater 211 is not ON (No in S201), the ECU 215 confirms whether the door heater 211 was driven until just before (S202). If the door heater 211 was driven until just before (Yes in S202), the ECU 215 continues to confirm whether the power supply of the door heater 211 is ON. If the door heater 211 was not driven (No in S202), the temperature of the door heater 211 is detected (S203), and it is confirmed whether the detected temperature is equal to or higher than a preset fourth temperature. If the detected temperature is not equal to or higher than the fourth temperature (No in S204), it continues to confirm whether the power supply of the door heater 211 is ON. If the temperature is equal to or higher than the fourth temperature (Yes in S204), the door heater 211 is not in use but the temperature is high due to the ambient temperature in the vehicle interior, so the illumination device 213 is made to emit light in a cool color. Specifically, the illumination color is set so that the B value is higher than the R value and the G value (S205), and the illumination device 213 is made to emit light (S206). Next, it is detected whether or not the display OFF has been selected (S207). If the display OFF has not been selected (No in S207), the illumination device 213 continues to emit light, and will continue to emit light until the display of the illumination device 213 is turned off by the occupant. If the occupant has selected OFF (Yes in S207), the illumination device 213 is turned off, and the process ends.

[0085] Furthermore, even when the power supply of the door heater 211 is turned off, the temperature of the heating wire 211a does not suddenly drop. Therefore, if the lighting device 213 is used to inform the passenger that the temperature has dropped after the power supply of the door heater 211 is turned off, the passenger can recognize that the temperature of the door heater 211 has dropped. Therefore, it is preferable to change the light emission color of the lighting device to a cool color when a certain time has passed since the power supply was turned off. More specifically, the elapsed time is measured after the door heater 211 is turned off, and after the certain time has passed, the light source unit is made to emit light in the third light emission mode. At this time, the B value indicating blue among the light emission colors emitted by the light source unit is set to be higher than the R value and the G value.

[0086] The above process will be described with reference to Fig. 12 and Fig. 14. First, it is confirmed whether the power supply of the door heater 211 is ON or not (S301). If the door heater 211 is ON (Yes in S301), the process S100 for changing the light emission color of the lighting device 213 shown in Fig. 11 is executed. If the door heater 211 is not ON (No in S301), the ECU 215 confirms whether the door heater 211 was driven immediately before (S302). If the door heater was not driven immediately before (No in S302), the process returns to S301 and continues to confirm whether the power supply of the door heater 211 is ON or not.

[0087] If the door heater 211 is driven (Yes in S302), the elapsed time from the time when the door heater 211 is turned OFF (time when the time becomes t3 in FIG. 12) is measured, and it is determined whether or not a predetermined time has elapsed (S303). If the predetermined time has not elapsed (No in S303), the process returns to S301. If the predetermined time has elapsed (Yes in S303), for example, when the time shown in FIG. 12 becomes t4, the ECU 215 sets the display content of the light source unit 213b to the third light emission mode and causes the illumination device 213 to emit light. Specifically, the illumination color of the illumination device 213 is set so that the B value is higher than the R value and the G value (S304), and the illumination device 213 emits light (S305). Thereafter, it is detected whether or not the display OFF has been selected (S306). When the display OFF is not selected (No in S306), the illumination device 213 continues to emit light, and the display of the illumination device 213 continues to emit light until it is turned OFF by the occupant. When the illumination device 213 selects OFF (Yes in S306), the illumination device 213 is turned off, that is, the display is ended.

[0088] By controlling the lighting device 213 in this way and adjusting the RGB values ​​to make the blue color darker when a predetermined time has elapsed since the power supply to the door heater 211 was turned off, it is possible to make it easier to visually recognize that the door heater 211 has cooled down.

[0089] In the vehicle door D2, the lighting device 213 is disposed near the door heater 211, more specifically, between the upper end 201a of the door trim 201 and the upper end 206a of the armrest 216 on which the door heater 211 is provided. By disposing the lighting device 213 near the door heater 211, it becomes easier for the occupant to associate the display of the lighting device 213 with the temperature of the door heater 211.

[0090] In the vehicle door D2, the lighting device 213 is disposed between the upper end 201a of the door trim 201 and the upper end of the upper end 206a of the armrest 206. Since the lighting device 213 is disposed above the armrest 206 where the arm is expected to be placed and at a position lower than the window member 202, the lighting device 213 can be seen at a position that is less susceptible to the influence of the brightness outside.

[0091] In the vehicle door D2, the door heater 211 is disposed in the central member 204 at the same position as the arm rest 206 at least in the front-rear direction. Since the lighting device 213 is disposed above the arm rest 206 where the occupant's arm is expected to be placed in contact with the door heater 211, the occupant can feel the warmth of the lighting device 213 at a highly visible position even with his / her arm against the door heater 211.

[0092] 8 to 14, the vehicle interior part 210 and the vehicle door D2 equipped with the vehicle interior part 210 according to another embodiment have been described. In the vehicle interior part 210, the lighting device 213 that emits light using the light source unit 213b using a light guide is used as the display device, but the display device is not limited to this and may be a lighting device in which a plurality of LEDs are arranged in a line as the light source unit, or the display device may be a liquid crystal panel. In addition, in the vehicle interior part 210, the temperature of the door heater 211 is detected as the thermal state, but this is just one example. If the positions to be heated by the door heater 211 can be individually controlled, the location may be displayed using a display device according to the position being heated.

[0093] Also, in order to display the lighting device 213 day or night, a POWER LED capable of emitting more powerful light with a stronger output may be used. In that case, it is necessary to suppress the temperature rise of the light emitter of the lighting device 213 by using a heat sink or a fan. In this case, the heat sink may be used instead of the door heater 211 which is a heating device. Also, when a fan is used for cooling, the hot air passing through the fan may be used as a heating device in place of the door heater 211. Not only can the number of parts be reduced, but the light emission energy of the light emitter can be effectively utilized while suppressing the temperature rise of the light emitter.
