[0004] However, sometimes passengers want to check for fallen objects on the floor inside the carriage when the sliding doors are closing. Generally, there are interior lights installed in the ceiling of the carriage, but it is difficult to ensure a clear view of the floor with ceiling-mounted lights. Therefore, it is possible to consider installing a light-emitting device that can illuminate the floor inside the carriage, but in this case, additional light-emitting devices, wiring, and installation space are required.

Detailed Implementation

[0009] [Description of embodiments of the present invention] First, embodiments of the present invention will be described. The wire harness of the present invention [1] A wiring harness is provided from the vehicle body to a sliding door that can be opened and closed relative to the vehicle body. The wiring harness has a light-emitting member, which is arranged in such a way that its orientation changes according to the opening and closing state of the sliding door, and is arranged to illuminate the floor of the passenger compartment around the sliding door when the sliding door is fully closed, and to illuminate the outside of the passenger compartment around the sliding door when the sliding door is fully open.

[0010] This structure allows for a single light-emitting component, ensuring good visibility of the ground when the sliding door is open and closed. For example, even at night, with the sliding door fully closed, passengers can easily spot objects falling from the floor. Furthermore, even at night, with the sliding door fully open, users can easily get on and off the vehicle.

[0011] [2] In the above [1], it is also possible to have multiple separate conveying members, which cover the wire group and are arranged along the extension direction of the wire group and are rotatably connected to each other, and the light-emitting member is fixed to at least one of the multiple separate conveying members.

[0012] According to this structure, multiple separate conveyor members are provided, which cover the wire assembly and are arranged along the extension direction of the wire assembly. They are rotatably connected to each other, and the light-emitting component is fixed to the separate conveyor members. Therefore, for example, the illuminated position of the light-emitting component can be stabilized. For example, in a structure where the wire assembly is only covered by a corrugated pipe, it can be freely bent at any point in the extension direction of the wire harness, and due to deterioration, the bending pattern may sometimes change, so the illuminated position of the light-emitting component is unstable. In contrast, even if the sliding door is repeatedly opened and closed, the multiple separate conveyor members can keep the bending pattern fixed, thus stabilizing the illuminated position of the light-emitting component.

[0013] [3] In the above [2], each of the plurality of separate conveying components may have a U-shaped separate conveying component body and a conveying component cover fixed in a manner that closes the opening of the separate conveying component body. The separate conveying component body is open in one direction that intersects the extension direction of the wire group and is U-shaped. The light-emitting component is fixed to the conveying component cover.

[0014] According to this structure, the light-emitting component is fixed to the conveyor cover. Therefore, compared to a structure that is fixed to the main body of a separate conveyor, the special component for fixing the light-emitting component can be a small component. That is, the light-emitting component can be fixed by simply changing a small part, so manufacturing becomes easier and cost increases can be suppressed.

[0015] [4] In the above [3], the conveyor cover may also have a light-transmitting portion, the light-emitting component is disposed inside the detachable conveyor in such a way that it illuminates the outside from the light-transmitting portion, and is fixed to the conveyor cover by a potting compound.

[0016] According to this structure, the light-emitting component is disposed inside the separable conveyor in such a way that it illuminates the outside through the light-transmitting portion of the conveyor cover, and is fixed to the conveyor cover by a potting compound, thus being stably fixed. In addition, the potting compound prevents the light-emitting component from being immersed in water.

[0017] [5] In any of the above [1] to [4], the light-emitting component may be configured to be positioned on the outer side of the vehicle body than the passenger boarding pedal when the sliding door is fully open, and the passenger boarding pedal is located in the vehicle body at a position corresponding to the sliding door.

[0018] According to this structure, the light-emitting member is positioned on the outer side of the vehicle body, beyond the passenger boarding and alighting pedal, when the sliding door is fully open. Therefore, it effectively illuminates the desired location, such as below the passenger boarding and alighting pedal. In contrast, in a structure where the light-emitting member is positioned on the inner side of the vehicle body beyond the outermost edge of the passenger boarding and alighting pedal, the passenger boarding and alighting pedal becomes an obstruction, making it difficult to illuminate the desired location, such as below the passenger boarding and alighting pedal. This structure effectively illuminates the desired location.

[0019] [6] In any of the above [1] to [5], the light-emitting member may also be configured to be positioned above the floor when the sliding door is fully closed.

[0020] According to this structure, the light-emitting component is positioned above the floor when the sliding door is fully closed, thus effectively illuminating the floor. That is, for example, in a structure where the light-emitting component is positioned below the floor, the floor cannot be directly illuminated, but in contrast, the floor can be directly and effectively illuminated.

[0021] The lighting system of the present invention [7] It comprises: a wiring harness as described in any one of [1] to [6] above; and a power control device for supplying power to the light-emitting component when the sliding door is in a fully closed state and when the sliding door is in a fully open state.

[0022] According to this structure, when the sliding door is fully closed or fully open, the power supply device supplies power to the light-emitting component. Therefore, it is possible to have only one light-emitting component, and at the same time, it can ensure good visibility underfoot when the sliding door is open or closed.

[0023] [8] In the above [7], it is also possible that if the sliding door becomes fully closed and a preset time has elapsed, the power control device stops supplying power to the light-emitting component. According to this structure, when the sliding door is fully closed, the power supply to the light-emitting component stops after a preset time. Therefore, for example, it is possible to immediately detect objects falling from the floor after a passenger has boarded the vehicle, and the light will automatically dim afterward.

[0024] [9] In the above [8], it is also possible to have a switch that can switch the power supply to the light-emitting component and stop the power supply after a preset time has elapsed since the sliding door is in the fully closed state.

[0025] According to this structure, a switch is provided. After a preset time has elapsed after the sliding door is fully closed, the switch can switch the power supply to the light-emitting component and stop the power supply. Therefore, the floor can be illuminated, for example, when a passenger wants to check for fallen objects on the floor.

[0026]

[10] In any of the above [7] to [9], the power control device may also supply power to the light-emitting component during the operation of the sliding door. According to this structure, since the light-emitting component is also powered during the operation of the sliding door, the user's surrounding vision can be ensured, for example, during the operation of the sliding door.

[0027]

[11] In the above

[10] , the power control device may supply power to the light-emitting component in a different light-emitting mode than when the sliding door is in a fully closed state and when the sliding door is in a fully open state.

[0028] According to this structure, during the operation of the sliding door, the light-emitting component is powered in a different way than when the sliding door is fully closed and when the sliding door is fully open. Therefore, for example, the user can recognize that the sliding door is in operation.

[0029] [Detailed Description of Embodiments of the Invention] Specific examples of the lighting system of the present invention will be described below with reference to the accompanying drawings. In the drawings, for ease of explanation, some parts of the structure are sometimes exaggerated or simplified. Furthermore, the dimensional ratios of the various parts sometimes differ in the drawings.

[0030] The terms "first," "second," etc., used in this specification are only for distinguishing objects and do not constitute a ranking of objects. This invention is not limited to these examples, but is shown through the claims and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0031] (Structure of Lighting System 1) like Figures 1 to 3 As shown, the lighting system 1 includes a wiring harness 10 and a power control device 100. The lighting system 1 is installed on the vehicle body 20 and sliding door 30.

[0032] (Structure of wire harness 10) The wiring harness 10 includes a wire assembly 11 that runs from the vehicle body 20 to the sliding door 30. The wire assembly 11 electrically connects a power control device 100 installed on the vehicle body 20 and an electrical device (not shown) installed on the sliding door 30. This electrical device may include, for example, an electric window motor or a lock actuator; the power control device 100 is a device for supplying power to these electrical devices. The vehicle body 20 has an opening 21 that can be opened and closed through the sliding door 30. Additionally, a step 22 for boarding and alighting is provided on the vehicle body 20. The step 22 is located at a position corresponding to the sliding door 30 and is positioned on the outer side of the opening 21. Figure 1 The lower end of the vehicle is near the inner side of the car. Figure 1The upper part of the vehicle body 20. The step 22 is for users to place their feet when getting on and off the vehicle. Additionally, the sliding door 30 is configured to open at the front and rear of the vehicle body 20 via a mechanism not shown. Figure 1 The sliding door 30 can slide left and right (as shown in the diagram). Specifically, the sliding door 30, via a mechanism not shown, can move from the fully closed state (see reference 1) to the fully closed state. Figure 1 ) To the outside of the vehicle body 20 ( Figure 1 It can move to the lower side of the vehicle body (20), and at the same time move to the rear of the vehicle body (20). Figure 2 Slide to the left of the middle, and can slide to the fully open state (see reference). Figure 3 ).

[0033] like Figure 5 As shown, the wiring harness 10 includes a wire assembly 11, multiple separate delivery components 12, a rubber sheath 13, and a light-emitting component 14. Additionally, Figure 5 The illustration shows a portion of the wire harness 10 after the detachable conveyor 12 and rubber sheath 13 have been disassembled. Additionally, the wire assembly 11 is constructed by bundling multiple wires, but these are schematically shown without illustrating the multiple wires themselves.

[0034] (Structure of multiple separate conveyor components 12) Multiple separate conveyor components 12 are made of resin material. Multiple separate conveyor components 12 cover the wire assembly 11 and are arranged along the extension direction of the wire assembly 11 and are rotatably connected to each other.

[0035] Specifically, each of the multiple detachable conveyor components 12 has: a U-shaped detachable conveyor body 15 with an opening in one direction intersecting the extension direction of the wire assembly 11; and a conveyor cover 16 fixed in a manner that closes the opening of the detachable conveyor body 15.

[0036] The detachable conveyor body 15 has a rotating shaft portion 15a at a first end and a rotatable shaft portion 15b at a second end that can be connected to the rotating shaft portion 15a. Furthermore, each of the multiple detachable conveyor bodies 15 is rotatably connected to the rotatable shaft portion 15b of an adjacent detachable conveyor body 15 via the rotating shaft portion 15a, thereby allowing rotation relative to the adjacent detachable conveyor body 15.

[0037] like Figure 6 and Figure 7 As shown, in this embodiment, the multiple separate conveyor members 12 have a first separate conveyor member 12A that can rotate at different angles (see reference). Figure 6 ) and the second separate conveyor 12B (refer to Figure 7 These two types. For example... Figure 6As shown, the first detachable conveyor 12A can rotate 15° counterclockwise in the first rotation direction from a straight position, and can rotate 30° clockwise in the second rotation direction from a straight position. Additionally, as... Figure 7 As shown, the second detachable conveyor 12 cannot rotate counterclockwise from a straight position in the first rotation direction (as shown in the figure), but can rotate 45° clockwise from a straight position in the second rotation direction (as shown in the figure). Furthermore, the angle at which the detachable conveyor 12 can rotate is set by a known structure that alters the shape of the engagement portion with adjacent detachable conveyors 12.

[0038] Furthermore, multiple separate conveyor components 12 prevent the wire harness 10 from extending beyond the anti-extension reference line Z (refer to...). Figure 3 ) 20 sides of the vehicle body ( Figure 3 The first separate conveyor 12A and the second separate conveyor 12B are combined in a manner that extends from the upper side of the vehicle body 20. In addition, the anti-outward extension reference line Z is, for example, a line set according to each vehicle model in a manner that maintains a fixed distance from the vehicle body 20.

[0039] And, as Figure 3 As shown, for example, in this embodiment, a second separate conveyor 12B (see reference) is used within the intermediate range X of the wire harness 10. Figure 7 This prevents the wiring harness 10 from protruding closer to the vehicle body 20 than the anti-outward reference line Z. Figure 3 It extends from the upper side of the wire harness 10. Therefore, it can prevent the wire harness 10 from colliding with the vehicle body 20. In addition, a first separate conveyor 12A (see reference) is used in the area outside the middle range X of the wire harness 10. Figure 6 In addition, of course, the combination of the first separate conveyor 12A and the second separate conveyor 12B can also be appropriately modified, for example, according to the anti-outward reference line Z set for each vehicle model.

[0040] (Structure of rubber sheath 13) The rubber sheath 13 is made of rubber material. like Figure 5 As shown, a rubber sleeve 13 is configured to cover a plurality of rotatably connected separate conveyor components 12. The rubber sleeve 13 is formed into a corrugated structure by repeatedly undulating in the extending direction. The rubber sleeve 13 is formed to be easily bent by the corrugated structure, allowing rotation of the plurality of separate conveyor components 12.

[0041] (Structure of light-emitting component 14) like Figure 1 and Figure 3 As shown, the light-emitting component 14 is arranged in a manner that changes orientation according to the opening and closing state of the sliding door 30. For example... Figure 1As shown, the light-emitting component 14 is configured to illuminate the floor F inside the carriage surrounding the sliding door 30 when the sliding door 30 is fully closed. Additionally, as... Figure 3 As shown, the light-emitting component 14 is configured to illuminate the exterior of the carriage surrounding the sliding door 30 when the sliding door 30 is fully open. Additionally, in Figure 1 and Figure 3 The diagram schematically illustrates the illumination ranges H1 and H2 of the light-emitting component 14.

[0042] In addition, such as Figure 4 As shown, in this embodiment, the light-emitting member 14 is positioned above the floor F when the sliding door 30 is fully closed. Furthermore, the light-emitting member 14 is configured to illuminate the floor F inside the carriage when the sliding door 30 is fully closed. Additionally, in Figure 4 The diagram shows a door trim 31 installed on a sliding door 30. The wiring harness 10 is positioned below the door trim 31 when the sliding door 30 is fully closed.

[0043] In addition, such as Figure 3 As shown, in this embodiment, the light-emitting component 14 is configured such that, when the sliding door 30 is fully open, at least a portion of it is positioned on the outer side of the vehicle body 20, closer to the passenger / passenger ramp 22. Figure 3 (Lower side of the vehicle body 20). Furthermore, in this embodiment, the light-emitting member 14 is configured such that, when the sliding door 30 is fully open, at least a portion of it is positioned on the outer side of the vehicle body 20, closer to the opening 21. Moreover, the light-emitting member 14 is configured to illuminate the area below the passenger boarding / alighting pedal 22, specifically the area on the outer side of the vehicle body 20 corresponding to the passenger boarding / alighting pedal 22, when the sliding door 30 is fully open.

[0044] like Figure 8 As shown, in this embodiment, the light-emitting component 14 is an LED substrate on which LED elements are mounted, and a lens 17 is fixed on its outer surface. Furthermore, the light-emitting component 14 is fixed to the conveyor cover 16 of the detachable conveyor 12.

[0045] In detail, the conveyor cover 16 on which the light-emitting member 14 is fixed has a through hole 16a serving as a light-transmitting portion. Furthermore, a typical conveyor cover 16 that does not fix the light-emitting member 14 does not have a through hole 16a; only the conveyor cover 16 on which the light-emitting member 14 is fixed is a special component of a different model. The through hole 16a opens obliquely downwards. Additionally, the rubber sleeve 13 has a rubber through hole 13a serving as a light-transmitting portion on the rubber sleeve side at a location corresponding to the through hole 16a.

[0046] Furthermore, the light-emitting component 14 is disposed inside the separate conveyor 12 such that it illuminates the outside through the through hole 16a and the rubber through hole 13a, and is fixed to the conveyor cover 16 by the potting member 18. In other words, the light-emitting component 14 is disposed inside the separate conveyor 12 such that it can illuminate light through the through hole 16a and the rubber through hole 13a, and is fixed to the conveyor cover 16 by the potting member 18. In addition, in this embodiment, the light-emitting component 14 is disposed in the through hole 16a with a lens 17. In addition, the potting member 18 fixes the power supply line 19 connected to the light-emitting component 14 together with the light-emitting component 14. The power supply line 19 forms part of the wire assembly 11 and is connected to the power control device 100 (see reference 100) provided on the vehicle body 20. Figures 1 to 3 )connect.

[0047] (Structure of power control device 100) The power control device 100 is electrically connected to a battery (not shown) and a door light switch (not shown). The power control device 100 is activated when the sliding door 30 is fully closed (see reference). Figure 1 When the sliding door 30 is fully open (refer to...) Figure 3 When the sliding door 30 is in operation, power is supplied to the light-emitting component 14. Additionally, in this embodiment, the power control device 100 supplies power to the light-emitting component 14 during the operation of the sliding door 30 (see reference 100). Figure 2 It also supplies power to the light-emitting component 14.

[0048] In detail, in this embodiment, the power control device 100 stops supplying power to the light-emitting component 14 after a preset time has elapsed after the sliding door 30 is fully closed. Furthermore, the preset time may be, for example, 10 seconds, 15 seconds, or a time set under certain other conditions.

[0049] In addition, such as Figure 1 As shown, the lighting system 1 in this embodiment includes a switch 40. The switch 40 is electrically connected to the power control device 100. The switch 40 is located in a position that can be operated by the passenger. The switch 40 is configured to switch the power supply to the light-emitting component 14 and stop the power supply after a preset time has elapsed after the sliding door 30 is fully closed.

[0050] Furthermore, in this embodiment, the power control device 100 supplies power to the light-emitting member 14 in a different manner than when the sliding door 30 is fully closed or fully open during operation of the sliding door 30. Specifically, in this embodiment, the power control device 100 supplies power by illuminating the light-emitting member 14 when the sliding door 30 is fully closed or fully open, and supplies power by flashing the light-emitting member 14 during operation of the sliding door 30.

[0051] (The function in this embodiment) Next, the function of the lighting system 1 configured as described above will be explained. For example, when the sliding door 30 is fully closed, power is supplied to the light-emitting member 14 from the power control device 100. Thus, when the sliding door 30 is fully closed, the light-emitting member 14 illuminates the floor F inside the carriage surrounding the sliding door 30. Furthermore, after a preset time has elapsed since the sliding door 30 was fully closed, the power supply to the light-emitting member 14 is stopped, and the light-emitting member 14 is turned off.

[0052] Additionally, for example, during the operation of the sliding door 30, power is supplied to the light-emitting component 14 from the power control device 100 to cause the light-emitting component 14 to flash. As a result, during the operation of the sliding door 30, the periphery of the sliding door 30 will repeatedly brighten or darken.

[0053] Additionally, for example, when the sliding door 30 is fully open, power is supplied to the light-emitting member 14 from the power control device 100. Thus, when the sliding door 30 is fully open, the light-emitting member 14 illuminates the exterior of the carriage surrounding the sliding door 30.

[0054] (Effects in this implementation method) Next, the effects of the above-described embodiments will be described. (1) The wiring harness 10 includes a light-emitting member 14, which is arranged so that its orientation changes according to the opening and closing state of the sliding door 30. The light-emitting member 14 is configured to illuminate the floor F inside the carriage around the sliding door 30 when the sliding door 30 is fully closed, and to illuminate the outside of the carriage around the sliding door 30 when the sliding door 30 is fully open. Therefore, a single light-emitting member 14 can be used to ensure good visibility underfoot when the sliding door 30 is open and closed. For example, even at night, when the sliding door 30 is fully closed, passengers can easily spot objects that may have fallen from the floor F. In addition, for example, even at night, when the sliding door 30 is fully open, users can easily get on and off the train.

[0055] (2) The wire harness 10 includes multiple separate conveyor members 12, which cover the wire assembly 11 and are arranged along the extension direction of the wire assembly 11, and are rotatably connected to each other. Furthermore, the light-emitting member 14 is fixed to the separate conveyor members 12, thus, for example, the illuminated position of the light-emitting member 14 can be stabilized. For example, in a structure where the wire assembly 11 is only covered by a corrugated pipe, it can be freely bent at any point in the extension direction of the wire harness 10, and due to deterioration, the bending pattern may sometimes change, thus the illuminated position of the light-emitting member 14 is unstable. In contrast, even with repeated opening and closing of the sliding door 30, the multiple separate conveyor members 12 can maintain a fixed bending pattern, thus stabilizing the illuminated position of the light-emitting member 14.

[0056] Furthermore, for example, in a structure where the wiring harness 11 is simply covered by a corrugated tube, the overall shape becomes a large arc when bent, potentially intruding into unwanted areas and possibly coming into contact with other components. In contrast, since multiple separate conveyor members 12 can maintain the bending pattern in a fixed manner, contact with other components can be stably prevented. Specifically, the wiring harness 10 can be prevented from extending towards the vehicle body 20 from the anti-extension reference line Z, thereby preventing collision with the vehicle body 20.

[0057] (3) Each of the multiple detachable conveyor components 12 has a U-shaped detachable conveyor body 15 with an opening in one direction intersecting the extension direction of the wire assembly 11, and a conveyor cover 16 fixed in a manner that closes the opening of the detachable conveyor body 15. Furthermore, the light-emitting member 14 is fixed to the conveyor cover 16. Therefore, compared to a structure fixed to the detachable conveyor body 15, the special component for fixing the light-emitting member 14 can be a smaller component. That is, the light-emitting member 14 can be fixed simply by changing a small component, thus making manufacturing easier and suppressing cost increases.

[0058] (4) The light-emitting component 14 is disposed inside the separable conveyor 12 in such a way that it illuminates the outside through the through hole 16a of the conveyor cover 16, and is fixed to the conveyor cover 16 by the potting member 18, thus being stably fixed. In addition, the potting member 18 can prevent the light-emitting component 14 from being immersed in water.

[0059] (5) The light-emitting member 14 is positioned on the outer side of the vehicle body 20, beyond the passenger boarding and alighting pedal 22, when the sliding door 30 is fully open. Therefore, it effectively illuminates the desired location, such as below the passenger boarding and alighting pedal 22. In contrast, in a configuration where the light-emitting member 14 is positioned on the inner side of the vehicle body 20 beyond the outermost edge of the passenger boarding and alighting pedal 22, the passenger boarding and alighting pedal 22 becomes an obstacle, making it difficult to illuminate the desired location, such as below the passenger boarding and alighting pedal 22. This configuration effectively illuminates the desired location.

[0060] (6) The light-emitting member 14 is configured to be positioned above the floor F when the sliding door 30 is fully closed, so that the floor F can be well illuminated. That is, for example, in a structure in which the light-emitting member 14 is positioned below the floor F, the floor F cannot be directly illuminated, but in contrast, the floor F can be directly and well illuminated.

[0061] (7) When the sliding door 30 is fully closed and when the sliding door 30 is fully open, power is supplied to the light-emitting component 14 through the power control device 100. Therefore, the light-emitting component 14 can be a single unit, and the field of vision underfoot can be automatically and well ensured when the sliding door 30 is open and closed.

[0062] (8) When the sliding door 30 is fully closed, after a preset time, the power supply to the light-emitting component 14 is stopped. Therefore, for example, the fallen objects on the floor F can be detected immediately after the passenger gets on the vehicle, and the light will automatically dim afterwards.

[0063] (9) It is equipped with a switch 40. After a preset time has elapsed after the sliding door 30 is fully closed, the switch 40 can switch the power supply to the light-emitting component 14 and stop the power supply. Therefore, for example, when the passenger wants to check for objects falling on the floor F, the floor F can be illuminated.

[0064] (10) Power is also supplied to the light-emitting component 14 during the operation of the sliding door 30, so that the user's surrounding vision can be ensured, for example, during the operation of the sliding door 30. (11) During the operation of the sliding door 30, power is supplied to the light-emitting component 14 in a different light-emitting mode than when the sliding door 30 is in the fully closed state and when the sliding door 30 is in the fully open state. Therefore, for example, the user can recognize that the sliding door 30 is in operation.

[0065] (Modified Example) The above embodiments can be implemented with the following modifications. The above embodiments and the following variations can be combined with each other within the scope of technical inconsistency.

[0066] In the above embodiment, the light-emitting component 14 is configured to be positioned above the floor F inside the carriage when the sliding door 30 is fully closed, but is not limited thereto.
