Summary of the Invention

Problems to be Solved by the Invention

[0004] In a vehicle lighting device, there is a desire to achieve a lighting effect with movement. Here, the "lighting effect with movement" refers to a lighting effect in which the appearance of the light emitted toward the vehicle interior changes over time. Conventionally, in order to achieve a lighting effect with movement, a method of changing the lighting of the light source over time is known. However, with such a configuration, there is a problem that the device (electric circuit, etc.) for electrically controlling the lighting of the light source becomes complicated, resulting in a complicated configuration of the lighting device.

[0005] The technology disclosed in this specification has been completed based on the above circumstances, and an object thereof is to provide a vehicle lighting device that can achieve a lighting effect with movement with a simpler configuration.

Means for Solving the Problems

[0006] To solve the above problems, the vehicle lighting device disclosed herein comprises a housing having a first light-transmitting portion that transmits light on the interior side of the vehicle, a light-emitting portion that emits light from the inside of the housing toward the interior of the vehicle, and a sheet member having a second light-transmitting portion that transmits light and is arranged inside the housing so as to cover the light-emitting portion from the inside of the vehicle. The sheet member is flexible, its upper end is fixed to the housing, while its lower end is in a swingable free state, a sheet-side magnetic material is provided at the lower end, and a housing-side magnetic material is provided at a position in the housing opposite to the sheet-side magnetic material that generates a magnetic force with the sheet-side magnetic material.

[0007] Here, "magnetic force" refers to the effect of generating repulsive (repelling) or attractive (attracting) forces when two objects are brought close together. With the above configuration, the lower end of the seat member can be moved closer to or further away from the light-emitting part based on the repulsive (repelling) or attractive (attracting) forces generated between the magnetic material on the seat side and the magnetic material on the housing side in conjunction with the vibrations during vehicle operation. As a result, the light emitted from the light-emitting part passes through the second light-transmitting part of the oscillating seat member and is then emitted into the vehicle interior through the first light-transmitting part of the housing, thereby achieving a dynamic lighting effect when viewed from inside the vehicle interior. Thus, with the above configuration, a dynamic lighting effect can be achieved with a simpler configuration without using equipment to operate the seat member or control circuits to electrically change the light from the light-emitting part.

[0008] The sheet-side magnetic material and the housing-side magnetic material may face each other in the direction of the vehicle's interior and exterior. Furthermore, the sheet-side magnetic material and the housing-side magnetic material may face each other in the vertical direction.

[0009] A hole may be provided in the lower wall portion of the housing, and both the sheet-side magnetic material and the housing-side magnetic material may be positioned inside the hole.

[0010] With the above configuration, the magnetic material on the sheet side and the magnetic material on the housing side do not obstruct the range of light propagation emitted from the light-emitting part, thus improving the freedom of design. Furthermore, since the displacement of the lower end of the sheet member can be restricted to a predetermined range, the desired lighting effect can be achieved more reliably. [Effects of the Invention]

[0011] The technology disclosed herein provides a vehicle lighting device that can achieve dynamic lighting effects with a simpler configuration. [Brief explanation of the drawing]

[Figure 5] Cross-sectional view of the sheet member and housing (cross-sectional view corresponding to line II-II in Figure 1) [Figure 6] A longitudinal cross-sectional view of a lighting device in another embodiment (corresponding to line II in Figure 1). [Modes for carrying out the invention]

[0013] One embodiment will be described with reference to Figures 1 to 5. In this embodiment, a lighting device 20 provided on a door trim 10, which is an interior material for a vehicle, will be given as an example of a vehicle lighting device. In each figure, the arrow direction FR will be the front of the vehicle, the arrow direction RR will be the rear of the vehicle, the arrow direction U will be upward, the arrow direction D will be downward, the arrow direction IN will be the inside of the vehicle interior, and the arrow direction OUT will be the outside of the vehicle interior.

[0014] The door trim (an example of an interior side) 10 is configured to cover the vehicle's door panel (not shown) from the inside of the vehicle, and as shown in Figure 1, it comprises a plate-shaped trim body 11. The trim body 11 has an armrest 12 that bulges outwards towards the interior of the vehicle, and an inside handle housing 13 that opens towards the interior of the vehicle. An inside handle (not shown) for opening and closing the vehicle door is housed in the inside handle housing 13. The trim body 11 is made of, for example, natural fibers and synthetic resin materials, but its material is not limited thereto. The lighting device 20 in this embodiment is provided above the armrest 12 and behind the inside handle housing 13, and has a rectangular surface shape when viewed from the front.

[0015] As shown in Figure 2, the lighting device 20 comprises a housing 30, a light source unit 21, a light-reflecting sheet 45, an ornament 50, and a sheet member 60.

[0016] The housing 30 is made of a material that has a refractive index sufficiently higher than that of air and is light-transmitting, such as a resin like acrylic or polycarbonate, or glass. As shown in Figure 2, the housing 30 is box-shaped and has an opening 30A that opens toward the interior of the vehicle.

[0017] More specifically, the housing 30 comprises a rectangular, plate-shaped bottom wall portion 31 that is positioned towards the rear when viewed from the inside of the vehicle and has a plate surface facing in the direction of the inside and outside of the vehicle, and is long in the front-rear direction of the vehicle; four side wall portions 34 that rise from the peripheral edge (four sides) of the bottom wall portion 31 toward the inside of the vehicle (left side in Figure 2); and flange portions 38 that are bent from the inside ends of the four side wall portions 34 toward the radially outward side of the bottom wall portion 31. Hereinafter, the upper side wall portion 34 of the four side wall portions 34 may be distinguished as the upper wall portion 34A, the lower side wall portion 34 as the lower wall portion 34B, the upper part of the flange portion 38 as the upper flange portion 38A, and the lower part as the lower flange portion 38B.

[0018] As shown in Fig. 2, in a portion of the bottom wall portion 31 adjacent to the lower end of the bottom wall portion 31, a light source slit 32 penetrating the plate surface in the vehicle interior and exterior direction extends in the vehicle front and rear direction, and a light source unit 21 is arranged inside the light source slit 32.

[0019] As shown in Fig. 2, the light source unit 21 includes a light source 22 and a substrate 23 on which the light source 22 is mounted. The light source 22 is constituted by, for example, an LED, but is not limited thereto. The substrate 23 has a longitudinal shape extending in the front and rear directions, and a plurality of light sources 22 are arranged along the longitudinal direction of the substrate 23. The light source unit 21 is arranged in the light source slit 32 with the light emitting surface 22A of the light source 22 facing upward. That is, the light emitting surface 22A of the light source 22 is disposed opposite to the surface 31A facing downward among the inner peripheral surfaces of the light source slit 32. As described above, since the bottom wall portion 31 (housing 30) is made of a light transmissive material, the light emitted from the light source 22 enters the bottom wall portion 31 from the surface 31A (hereinafter referred to as the light incident surface 31A) facing downward among the inner peripheral surfaces of the light source slit 32, and is made to be able to conduct light throughout the bottom wall portion 31. That is, the bottom wall portion 31 functions as a light guide plate.

[0020] Specifically, the light emitted from the light emitting surface 22A of the light source 22 enters the inside of the bottom wall portion 31 from the light incident surface 31A, and then is guided by total reflection inside the bottom wall portion 31, and is set to be emitted into the vehicle interior from the light emitting surface (an example of a light emitting portion) 31B which is the vehicle interior surface of the bottom wall portion 31. As shown in Fig. 2, on the surface of the bottom wall portion 31 on the vehicle exterior side, a plurality of recesses 33 are formed for reflecting the light inside the bottom wall portion 31 to the vehicle interior side and emitting it from the light emitting surface 31B. The configuration for emitting the light inside the bottom wall portion 31 from the light emitting surface 31B is not limited to the recesses 33. For example, a dot pattern for diffusely reflecting the light inside the bottom wall portion 31 may be formed on the surface of the bottom wall portion 31 on the vehicle exterior side.

[0021] Also, as shown in FIG. 2, on the vehicle exterior side (outside the passenger compartment, the right side in FIG. 2) of the bottom wall portion 31, a light reflection sheet 45 is disposed so as to cover the bottom wall portion 31. The light reflection sheet 45 enables the light emitted from the bottom wall portion 31 to the vehicle exterior side to be reflected to the vehicle interior side. The light reflection sheet 45 has at least its vertical dimension larger than the vertical dimension of the bottom wall portion 31, and covers the entire housing 30 from the vehicle exterior side. That is, the upper and lower portions of the light reflection sheet 45 extend vertically from the bottom wall portion 31 of the housing 30, and their ends are each in a folded state. As the light reflection sheet 45, for example, a synthetic resin-made sheet having a white surface excellent in light reflectivity can be used, but it is not limited thereto, and any configuration capable of reflecting light to the vehicle interior side may be used.

[0022] An ornament (an example of a housing) 50 is provided so as to close the opening 30A of the housing 30 from the vehicle interior side. The ornament 50 is a decorative member and includes a base material 51 made of a synthetic resin material having light transmissivity (for example, acrylic, polycarbonate, etc.) and a decorative film 55 attached to the surface of the base material 51 on the vehicle interior side (see FIG. 2).

[0023] The base material 51 has a rectangular plate shape that is long in the vehicle front-rear direction, and includes a base material main body portion 52 that is slightly larger than the outer shape of the housing 30, and locking protrusions 53A and 53B that protrude from the vehicle exterior side surface of the base material main body portion 52 toward the vehicle exterior side. The upper locking protrusion 53A provided closer to the upper end of the base material main body portion 52 among the locking protrusions 53A and 53B has a larger protrusion dimension from the base material main body portion 52 than the lower locking protrusion 53B provided closer to the lower end of the base material main body portion 52. A pattern or the like is printed on the surface of the decorative film 55. In addition, an opening (an example of a first light transmission portion) 56 that allows light to pass through is provided in a region of the decorative film 55 that faces the bottom wall portion 31 (light emission surface 31B, light emitting portion) of the housing 30 described above.

[0024] As shown in Figure 2, the trim body portion 11 is provided with a receiving recess 14 that is recessed from the interior surface to the exterior surface of the vehicle, into which the ornament 50 described above is fitted and which can accommodate the flange portion 38 of the housing 30, and a housing receiving hole 15 that penetrates in the interior-exterior direction in the bottom surface portion 14A of the receiving recess 14 and can accommodate the portion of the housing 30 other than the flange portion 38 (bottom wall portion 31 and side wall portion 34) inside. The portion of the bottom surface portion 14A of the receiving recess 14 that is located above the housing receiving hole 15 is made up of the interior surface of a support portion 16 that is thick in the interior-exterior direction. The exterior surface of the support portion 16 is located outside the vehicle from the light-reflecting sheet 45. In addition, the corner portion of the block-shaped support portion 16 located on the exterior side and at the lower end is a notch portion 17 with a cross section cut out in a substantially L shape. The notched portion 17 is a part that includes a horizontal portion 17A extending in the front-rear direction with the notched surface facing downwards, and a vertical portion 17B extending in the front-rear direction with the notched surface facing outwards from the vehicle interior.

[0025] The upper flange portion 38A of the housing 30 described above is superimposed on the bottom surface portion 14A of the housing recess 14 (the interior surface of the support portion 16). The upper portion of the base body portion 52 of the ornament 50 is also superimposed on the interior surface of the upper flange portion 38A of the housing 30. The upper locking projection 53A of the ornament 50 described above is positioned to penetrate the superimposed upper flange portion 38A and the lower portion of the support portion 16 where the notch portion 17 is provided, in the direction of in-vehicle A locking claw is provided at the tip (the end on the outside of the vehicle interior) of the upper locking projection 53A, and the upper locking projection 53A, which is inserted from the inside of the vehicle interior through the upper flange side hole 39A and the support side hole 18, locks the locking claw at its tip to the outside surface of the support 16 (the vertical surface 17B of the notch 17), thereby attaching the ornament 50 and housing 30 to the support 16 of the door trim 10.

[0026] On the other hand, in the state in which the upper portion of the ornament 50 and the upper flange portion 38A of the housing 30 are attached to the support portion 16 of the door trim 10, the lower end of the housing 30 is positioned at a location separated upward from the lower surface portion 15A located on the lower side of the inner circumferential surface of the housing housing hole 15 of the door trim 10. Furthermore, the lower portion of the base material body portion 52 of the ornament 50 overlaps with the interior surface of the lower flange portion 38B of the housing 30 and extends to the lower end of the housing recess 14. The lower locking projection 53B of the ornament 50 described above is provided at a position in the base material body portion 52 that overlaps with the lower flange portion 38B. The lower flange portion 38B is provided with a lower flange side hole portion 39B through which the lower locking projection 53B can be inserted. A locking claw is provided at the tip (the end on the outside of the vehicle interior) of the lower locking projection 53B, and the lower locking projection 53B, which is inserted through the side hole 39B of the lower flange from the inside of the vehicle interior, locks the locking claw provided at its tip onto the outside of the vehicle interior of the lower flange 38B, thereby attaching the lower part of the ornament 50 to the housing 30.

[0027] Furthermore, in the state in which the ornament 50 and housing 30 are attached to the trim body portion 11, a sheet holding groove 17C extends in the vehicle longitudinal direction to fit, position, and hold the upper end of the light-reflective sheet 45 into the position corresponding to the upper end of the light-reflective sheet 45 on the side surface portion 17A of the notch portion 17 of the support portion 16 described above. In addition, a support wall 19 rises upward from the lower surface portion 15A located on the lower side of the inner circumferential surface of the housing housing hole 15 to support the lower end of the light-reflective sheet 45 from the outside of the vehicle interior. In this embodiment, the support wall 19 is set to rise from the end of the lower surface portion 15A on the outside of the vehicle interior. In this embodiment, the length of the light-reflective sheet 45 is set so that its lower end is supported from below by the lower surface portion 15A.

[0028] In this embodiment, a sheet member 60 having light-shielding and flexible properties is placed inside the housing 30. The sheet member 60 is made of, for example, synthetic resin or Japanese paper.

[0029] As shown in Figures 2 and 3, the seat member 60 comprises a seat body portion 61 and a mounting portion 63. The seat body portion 61 is the part that is positioned opposite the interior surface (light emitting surface 31B) of the bottom wall portion 31 of the housing 30, and has a rectangular shape with dimensions that allow it to cover the entire bottom wall portion 31 from the interior side of the vehicle. As shown in Figure 3, the seat body portion 61 has multiple stages of elongated through holes (an example of a second light transmitting portion) 62 formed in the vehicle's front-rear direction, and a pattern is formed by these through holes 62. The shape of the through holes 62 is not limited to elongated holes and can be changed as appropriate.

[0030] The mounting portion 63 is a part that is bent in an L-shape at the upper end of the seat body portion 61 and extends outward from the vehicle interior. The upper wall portion 34A of the housing 30 described above is provided with a seat insertion slit 35 that extends in the front-rear direction of the vehicle (see Figure 2), and the mounting portion 63 of the seat member 60 is formed by pulling the upper end of the seat member 60 out from the inside of the housing 30 through the seat insertion slit 35 to above the upper wall portion 34A and bending it outward from the vehicle interior.

[0031] Multiple mounting holes 64 are formed in the mounting portion 63, aligned in the longitudinal direction of the vehicle (see Figure 3). Of the upper wall portion 34A of the housing 30 described above, multiple mounting protrusions 36 projecting upward are formed in the longitudinal direction of the vehicle, on the side of the seat insertion slit 35 that is on the side of the vehicle interior. By inserting these mounting protrusions 36 into the mounting holes 64 of the mounting portion 63 of the seat member 60, the upper end of the seat member 60 is attached to the housing 30. The lower end of the seat member 60 is not attached to the housing 30, and the seat member 60 is suspended inside the housing 30. In other words, the lower end of the seat member 60 is in a swingable free state (free end).

[0032] Furthermore, as shown in Figure 3, a rod-shaped sheet-side magnet (an example of a sheet-side magnetic material) 65 is attached to the lower end of the sheet member 60 in this embodiment by wrapping the lower end of the sheet member 60 inward towards the vehicle interior. In addition to its function as a magnet, this sheet-side magnet 65 also functions as a weight to stabilize the sheet member 60.

[0033] Of the lower wall portion 34B of the housing 30 described above, a magnet housing hole (an example of a hole) 37 is formed vertically through the lower wall portion 34B at a position that overlaps with the sheet insertion slit 35 of the upper wall portion 34A, and is wider than the sheet insertion slit 35 and has the same front-to-back length as the sheet insertion slit 35 (see Figure 2). The length of the sheet member 60 is set such that when its upper end (mounting portion 63) is attached to the upper wall portion 34A of the housing 30, the sheet-side magnet 65 is positioned inside the magnet housing hole 37 (see Figures 2 and 4). The magnet housing hole 37 is set to a size such that when the sheet member 60 is in its natural state, as described later, its inner circumferential surface is separated from the sheet member 60 (sheet-side magnet 65).

[0034] Furthermore, on the inner surface 37A of the magnet housing hole 37 that extends in the front-rear direction on the vehicle interior side, multiple housing-side magnets (an example of a housing-side magnetic material) 40 are intermittently attached to generate magnetic force in relation to the aforementioned seat-side magnet 65 (see Figure 4). Here, "magnetic force" refers to the effect of generating repulsive force (force that repels) or attractive force (force that attracts) when brought close to each other. In this embodiment, the seat-side magnet 65 and the housing-side magnet 40 are in a combination that generates repulsive force. Specifically, the seat-side magnet 65 and the housing-side magnet 40 are in a combination of N poles together or S poles together.

[0035] As shown in Figure 2, the housing-side magnet 40 is mounted on the inner surface 37A of the magnet housing hole 37 at a height opposite to the seat-side magnet 65 in the direction of the vehicle interior and exterior. The magnet housing hole 37 is set to a size such that the housing-side magnet 40 is separated from the seat member 60 (seat-side magnet 65) when the seat member 60 is in its natural state. The natural state includes the case in which no magnetic force is generated between the seat-side magnet 65 and the housing-side magnet 40, and also includes the case in which the position is stable when a magnetic force is generated. In this embodiment, as shown in Figure 2, in the natural state, the seat member 60 hangs straight down in the vertical direction. In such a state, the distance between the seat-side magnet 65 and the housing-side magnet 40 is large, and no magnetic force (repulsive force) is generated, or a magnetic force (repulsive force) is generated, but that magnetic force is stable as it matches the distance between the straight-extending seat body and the housing-side magnet.

[0036] Furthermore, the sheet-side magnet 65 and the housing-side magnet 40 can be a combination that utilizes the attractive force between magnets, or one can be a magnet and the other a magnetic material such as iron. In short, any combination that generates magnetic force when brought close together is acceptable, and is not limited to this embodiment.

[0037] With this configuration, for example, if the lower end of the free end of the seat member 60 oscillates within the magnet housing hole 37 due to vibrations during vehicle operation, the lower end of the seat member 60 will move in a more complex manner compared to a case where the seat-side magnet 65 and housing-side magnet 40 are not provided. This is because the range of oscillation of the lower end of the seat member 60 is restricted to a predetermined width by the inner circumferential surface of the magnet housing hole 37, and a repulsive force acts between the seat-side magnet 65 and the housing-side magnet 40. As a result, the light emitted from the light-emitting surface 31B of the housing 30 undergoes a significant change in state as it passes through the through-hole 62 of the seat body 61, and is emitted towards the vehicle interior through the opening 30A of the housing 30 and the opening 56 of the decorative film 55.

[0038] Next, the effects of this embodiment will be described. The lighting device 20 of this embodiment includes an ornament 50 having a light-transmitting opening 56 on the side of the interior of the vehicle (door trim 10), a light-emitting surface 31B (bottom wall portion 31) that emits light toward the interior of the vehicle from the inside of the housing 30 when the opening 30A is blocked by the ornament 50, and a sheet member 60 that is arranged inside the housing 30 to cover the light-emitting surface 31B from the inside of the vehicle and has a light-transmitting through hole 62. The sheet member 60 is flexible, its upper end is fixed to the housing 30, while its lower end is in a swingable free state, and a sheet-side magnet 65 is provided at the lower end, and a housing-side magnet 40 that generates a magnetic force with the sheet-side magnet 65 is provided in the housing 30 at a position opposite to the sheet-side magnet 65.

[0039] According to the above configuration, the lower end of the seat member 60 can be moved closer to or further away from the light-emitting surface 31B based on the magnetic force (repulsive force) generated between the seat-side magnet 65 and the housing-side magnet 40 in response to vibrations during vehicle operation. As a result, the light emitted from the light-emitting surface 31B passes through the through-hole 62 of the oscillating seat member 60 and is then emitted into the vehicle interior through the opening 56 of the ornament 50, thereby achieving a dynamic lighting effect when viewed from inside the vehicle interior. Thus, with the above configuration, a dynamic lighting effect can be achieved with a simpler configuration without using equipment to operate the seat member 60 or control circuits to electrically change the light from the light-emitting part.

[0040] Furthermore, the seat-side magnet 65 and the housing-side magnet 40 are facing each other in the direction of the interior and exterior of the vehicle. With this configuration, the lower end of the seat member 60 moves in the direction of the interior and exterior of the vehicle, thereby moving closer to or further away from the light-emitting surface 31B, and thus changing the amount of light emitted into the vehicle.

[0041] Furthermore, a magnet housing hole 37 is provided in the lower wall portion 34B located at the bottom of the housing 30, and both the sheet-side magnet 65 and the housing-side magnet 40 are positioned inside the magnet housing hole 37.

[0042] With the above configuration, the sheet-side magnet 65 and the housing-side magnet 40 do not obstruct the range of light propagation emitted from the light-emitting surface 31B, thus improving the freedom of design. Furthermore, since the displacement of the lower end of the sheet member 60 can be restricted to a predetermined range (within the magnet housing hole 37), the desired lighting effect can be achieved more reliably. <Other Embodiments> The technologies disclosed herein are not limited to the embodiments described above in the description and drawings, but also include, for example, the following embodiments.

[0043] (1) In the above embodiment, a configuration in which both the sheet-side magnetic material and the housing-side magnetic material are magnets is shown, but one may be a magnet and the other a magnetic material such as iron. Also, in the above embodiment, a configuration that utilizes the repulsive force (repulsive force) of magnetic materials is shown, but a configuration that utilizes the attractive force (attractive force) of magnetic materials can also be used.

[0044] (2) In the above embodiment, the seat-side magnet 65 and the housing-side magnet 40 are shown facing each other in the direction of the inside and outside of the vehicle. However, as shown in Figure 6, the seat-side magnetic material 165 and the housing-side magnetic material 140 may be shown facing each other in the vertical direction. In the lighting device 120 shown in Figure 6, the same parts as in the above embodiment are denoted by the same reference numerals as in the above embodiment.

[0045] (3) When the sheet-side magnetic material and the housing-side magnetic material are positioned facing each other in the direction of the vehicle interior and exterior within the hole (magnet housing hole), the housing-side magnetic material may be positioned on the outer surface of the inner circumferential surface of the hole. Alternatively, the housing-side magnetic material may be embedded in the inner circumferential surface of the hole.

[0046] (4) The magnet housing hole 37 (hole portion) can be omitted, in which case the sheet-side magnetic material and the housing-side magnetic material can be placed facing each other inside the housing (above the lower wall portion) (see Figure 6).

[0047] (5) In the above embodiment, the magnet housing hole 37 (hole) is formed by penetrating the lower wall portion 34B of the housing 30 in the vertical direction, but the hole can also be a recess that is recessed from the lower wall portion.

[0048] (6) The method for attaching the sheet-side magnetic material to the sheet member is not limited to the above embodiment.

[0049] (7) In the above embodiment, the sheet-side magnet 65 was made longitudinal and the housing-side magnet 40 was shown as being arranged intermittently in multiple units. However, the sheet-side magnetic material can be made from multiple units and the housing-side magnetic material can be made longitudinal. In addition, both the sheet-side magnetic material and the housing-side magnetic material can be made longitudinal, or both can be made from multiple units.

[0050] (8) In the above embodiment, an opening 56 was exemplified as the first light-transmitting portion, but the first light-transmitting portion may be made of a light-transmitting material instead of the opening 56.

[0051] (9) In the above configuration, a through hole 62 was given as an example for the second light-transmitting portion, but the second light-transmitting portion may be made of a light-transmitting material instead of a through hole 62.
