Description

Wire harness

[0001] The present disclosure relates to a wire harness.

[0002] Conventionally, there has been a wire harness including a group of electric wires routed from a vehicle body to a door that can be opened and closed relative to the vehicle body (see, for example, Patent Document 1). The group of electric wires electrically connects a power supply device provided in the vehicle body to an electrical device provided in the door. The door includes, as the electrical device, for example, a power window motor, a lock actuator, and a light-emitting element. The light-emitting element illuminates the area around the door when the door is in an open position, thereby assisting a user in getting in and out of the vehicle.

[0003] Japanese Patent Application Laid-Open No. 2003-327041

[0004] However, in the above-described configuration, the electric wires required for the light-emitting element provided on the door are long. Specifically, for example, the electric wires of the wire harness are connected to a connector provided on the door, and further electric wires are required from the connector to the light-emitting element, so the electric wires required from the vehicle body to the light-emitting element are long. In particular, when the door is a sliding door, the length of the electric wires from the vehicle body to the door tends to be long, so the electric wires required from the vehicle body to the light-emitting element are even longer.

[0005] An object of the present disclosure is to provide a wire harness that enables reduction in the number of electric wires.

[0006] The wire harness of the present disclosure includes a group of electric wires routed from a vehicle body to a door that can be opened and closed relative to the vehicle body, and a light-emitting member that illuminates the periphery of the door.

[0007] According to the wire harness of the present disclosure, it is possible to reduce the number of electric wires.

[0008] Fig. 1 is a schematic diagram of a part of a vehicle in one embodiment as seen from above. Fig. 2 is a partially exploded perspective view of a wire harness in one embodiment. Fig. 3 is a plan view for explaining types of separate bear elements in one embodiment. Fig. 4 is a plan view for explaining types of separate bear elements in one embodiment. Fig. 5 is a cross-sectional view of a wire harness in one embodiment.

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described. A wire harness of the present disclosure includes: [1] a group of electric wires routed from a vehicle body to a door that can be opened and closed relative to the vehicle body, and a light-emitting member that illuminates the periphery of the door.

[0010] According to this configuration, since the wire harness is provided with a light-emitting member that illuminates the area around the door, it is possible to reduce the number of electric wires compared to a configuration in which the light-emitting member is provided on the door, for example. Specifically, for example, in a configuration in which the light-emitting member is provided on the door, an electric wire is required from the vehicle body to the light-emitting member provided on the door, but since the wire harness routed from the vehicle body to the door is provided with the light-emitting member, the path of the electric wire from the vehicle body to the light-emitting member is shortened. Therefore, it is possible to reduce the number of electric wires.

[0011] [2] In the above [1], the door may be a sliding door. According to this configuration, the door is a sliding door, which allows for greater reduction in the amount of electrical wiring required compared to, for example, side doors or tailgates that open and close by pivoting around an axis. That is, compared to side doors or tailgates, the length of electrical wiring from the vehicle body to the door tends to be longer with a sliding door. However, since this configuration allows for shortening some of the electrical wiring, the effect of reducing the amount of wiring is greater. Furthermore, for example, with a configuration in which a light-emitting element is provided on the sliding door, it is difficult to illuminate a desired position, such as below a boarding / exiting step. However, with this configuration, it is possible to illuminate the desired position well. Furthermore, for example, with a configuration in which a light-emitting element is provided on the sliding door, the illuminated position changes continuously during the opening and closing operation of the sliding door. In contrast, for example, it is possible to illuminate a fixed position after the initial opening operation.

[0012] [3] In the above [2], a plurality of separate bare elements may be provided which cover the group of electric wires, are arranged in parallel along the extending direction of the group of electric wires, and are rotatably connected to each other, and the light-emitting member may be fixed to at least one of the plurality of separate bare elements.

[0013] According to this configuration, the wire harness includes a plurality of separate bare elements that cover the wire group, are arranged in parallel along the wire group's extension direction, and are rotatably connected to each other, and the light emitting member is fixed to the separate bare elements, so that, for example, the position illuminated by the light emitting member can be stabilized. For example, if the wire group is simply covered by a corrugated tube, the wire harness can bend freely at any position along the wire group's extension direction, and the bending pattern may change due to deterioration, etc., resulting in an unstable position illuminated by the light emitting member. In contrast, the multiple separate bare elements can maintain a constant bending pattern even when the sliding door is repeatedly opened and closed, so the position illuminated by the light emitting member can be stabilized.

[0014] [4] In the above [3], each of the plurality of separate bear elements has a U-shaped separate bear body with an opening on one side in a direction intersecting the extension direction of the group of electric wires, and a bear cover fixed to close the opening of the separate bear body, and the light-emitting member may be fixed to the bear cover.

[0015] According to this configuration, since the light emitting member is fixed to the bear cover, the special member to which the light emitting member is fixed can be made smaller than, for example, a configuration in which the light emitting member is fixed to the separate bear main body. In other words, since the light emitting member can be fixed by simply changing the small member, for example, manufacturing becomes easier and costs can be reduced.

[0016] [5] In the above [4], the bear cover may have a light-transmitting portion, and the light-emitting member may be arranged inside the separate bear element so as to illuminate the area around the sliding door from the light-transmitting portion, and may be fixed to the bear cover by a potting material.

[0017] According to this configuration, the light-emitting member is disposed inside the separate bear element so as to illuminate the area around the sliding door through the light-transmitting portion of the bear cover, and is fixed to the bear cover by the potting material, so that the light-emitting member is stably fixed. In addition, the potting material prevents the light-emitting member from being wet.

[0018] [6] In any one of [2] to [5] above, the light-emitting element may be configured to be positioned outside the vehicle body relative to a boarding / exiting step provided at a position on the vehicle body corresponding to the sliding door when the sliding door is fully open.

[0019] According to this configuration, the light-emitting member is set to be positioned on the outer side of the vehicle body relative to the entry / exit steps when the sliding door is fully open, so that the desired position, such as below the entry / exit steps, can be well illuminated. That is, for example, in a configuration in which the light-emitting member is positioned on the inner side of the outermost entry / exit steps on the vehicle body, the entry / exit steps get in the way, making it difficult to illuminate the desired position, such as below the entry / exit steps. In contrast, it is possible to well illuminate the desired position.

[0020] [Details of the Embodiments of the Present Disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. In each drawing, for the convenience of explanation, some of the configurations may be exaggerated or simplified. Furthermore, the dimensional proportions of each part may differ from one drawing to another. Furthermore, the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0021] (Configuration of Wire Harness 10) As shown in FIG. 1 , the wire harness 10 includes a group of electric wires 11 routed from a vehicle body 20 to a sliding door 30 serving as a door in a vehicle. The group of electric wires 11 electrically connects a power supply device (not shown) provided in the vehicle body 20 to an electrical device (not shown) provided in the sliding door 30. The electrical device may be, for example, a power window motor or a lock actuator, and the power supply device is a device for supplying power to the electrical device. The vehicle body 20 has an opening 21 that can be opened and closed by the sliding door 30. The vehicle body 20 also has an access step 22 provided in a portion corresponding to the sliding door 30, the access step 22 being located closer to the interior side (upper side in FIG. 1 ) of the vehicle than the outer side (lower side in FIG. 1 ) of the opening 21. The access step 22 is provided for a user to place their feet when getting in and out of the vehicle. The sliding door 30 is also provided slidably forward and backward (right and left in FIG. 1 ) of the vehicle body 20 by a mechanism (not shown). FIG. 1 illustrates an open state in which the sliding door 30 has been slid rearward (leftward in FIG. 1) of the vehicle body 20, leaving the opening 21 open.

[0022] As shown in Fig. 2, the wire harness 10 includes an electric wire group 11, a plurality of separate bare elements 12, a rubber boot 13, and a light emitting member 14. Fig. 2 illustrates the wire harness 10 in a state in which one separate bare element 12 and the rubber boot 13 are disassembled. The electric wire group 11 is formed by bundling a plurality of electric wires, but in the drawing, the plurality of electric wires are not shown and are simply illustrated together.

[0023] (Configuration of the Multiple Separate Bear Elements 12) The multiple separate bear elements 12 are made of a resin material. The multiple separate bear elements 12 cover the electric wire group 11, are arranged side by side along the extending direction of the electric wire group 11, and are rotatably connected to each other.

[0024] Specifically, each of the multiple separate bear elements 12 has a U-shaped separate bear main body 15 that is open on one side in a direction that intersects with the extension direction of the group of electric wires 11, and a bear cover 16 that is fixed so as to close the opening of the separate bear main body 15.

[0025] The separate bear main body 15 has a rotating shaft 15a at a first end and a rotated shaft 15b at a second end to which the rotating shaft 15a can be connected. Each of the multiple separate bear main bodies 15 is rotatable relative to the adjacent separate separate bear main body 15 by having the rotating shaft 15a rotatably connected to the rotated shaft 15b of the adjacent separate separate bear main body 15.

[0026] As shown in Figures 3 and 4, the multiple separate bear elements 12 in this embodiment are of two types: a first separate bear element 12A and a second separate bear element 12B, which have different rotation angles. As shown in Figure 3, the first separate bear element 12A is rotatable 15° counterclockwise from a straight state in a first rotation direction and 30° clockwise from a straight state in a second rotation direction. As shown in Figure 4, the second separate bear element 12B is not rotatable counterclockwise from a straight state in the first rotation direction and is rotatable 45° clockwise from a straight state in the second rotation direction. The rotation angle of the separate bear element 12 is set by a known structure, such as changing the shape of the engagement portion with the adjacent separate bear element 12.

[0027] The plurality of separate bare elements 12 are formed by combining a first separate bare element 12A and a second separate bare element 12B so that the wire harness 10 does not protrude beyond a protrusion prevention line Z (see FIG. 1) toward the vehicle body 20 (upper side in FIG. 1). The protrusion prevention line Z is a line set for each vehicle model so as to maintain a certain distance from the vehicle body 20 along the vehicle body 20, for example.

[0028] 1, for example, in this embodiment, the second separate bear element 12B (see FIG. 4) is employed in the middle range X of the wire harness 10. This prevents the wire harness 10 from protruding toward the vehicle body 20 (upper side in FIG. 1) beyond the protrusion prevention line Z. This prevents the wire harness 10 from colliding with the vehicle body 20. Note that the first separate bear element 12A (see FIG. 3) is employed in the range other than the middle range X of the wire harness 10. Of course, the combination of the first separate bear element 12A and the second separate bear element 12B may be changed as appropriate depending on, for example, the protrusion prevention line Z set for each vehicle model.

[0029] (Configuration of Rubber Boot 13) The rubber boot 13 is made of a rubber material. As shown in Fig. 2, the rubber boot 13 is provided to cover the multiple separate bearing elements 12 that are rotatably connected. The rubber boot 13 is formed to be easily bendable due to its bellows structure, allowing the multiple separate bearing elements 12 to rotate.

[0030] (Configuration of Light-Emitting Member 14) As shown in FIG. 1 , the light-emitting member 14 is provided on the wire harness 10 so as to illuminate the periphery of the sliding door 30, specifically, for example, the periphery on the vehicle exterior side of the opening 21 of the vehicle body 20, when the sliding door 30 is in an open state. Note that FIG. 1 schematically illustrates an illumination range H of the light-emitting member 14. Specifically, the light-emitting member 14 of this embodiment is configured so that at least a portion thereof is located outside the vehicle body 20 (lower side in FIG. 1 ) relative to the step 22 for getting in and out when the sliding door 30 is in a fully open state. Furthermore, the light-emitting member 14 of this embodiment is configured so that at least a portion thereof is located outside the vehicle body 20 relative to the opening 21 of the vehicle body 20 when the sliding door 30 is in a fully open state. The light-emitting member 14 is provided so as to illuminate the area below the step 22 for getting in and out, specifically, the area below the outside of the vehicle body 20 at a position corresponding to the step 22, when the sliding door 30 is in a fully open state.

[0031] 5, the light emitting member 14 of this embodiment is an LED board on which an LED element is mounted, and has a lens 17 fixed to its outer surface. The light emitting member 14 is fixed to the bear cover 16 of the separate bear element 12.

[0032] Specifically, the bear cover 16 to which the light emitting member 14 is fixed has a through-hole 16a as a light-transmitting portion. A normal bear cover 16 to which the light emitting member 14 is not fixed does not have the through-hole 16a, and only the bear cover 16 to which the light emitting member 14 is fixed is a special member with a different product number. The through-hole 16a opens diagonally downward. The rubber boot 13 also has a rubber through-hole 13a as a light-transmitting portion on the rubber boot side at a position corresponding to the through-hole 16a.

[0033] The light emitting member 14 is disposed inside the separate bare element 12 so as to illuminate the periphery of the sliding door 30 through the through-hole 16a and the rubber through-hole 13a, and is fixed to the bear cover 16 by the potting material 18. In other words, the light emitting member 14 is disposed inside the separate bare element 12 so as to be able to irradiate light through the through-hole 16a and the rubber through-hole 13a, and is fixed to the bear cover 16 by the potting material 18. In this embodiment, the light emitting member 14 is disposed so that the lens 17 is disposed inside the through-hole 16a. The potting material 18 also fixes a power supply line 19 connected to the light emitting member 14 together with the light emitting member 14. The power supply line 19 constitutes part of the electric wire group 11 and is connected to a power supply device provided in the vehicle body 20. This power supply device supplies power to the light emitting member 14 via the power supply line 19 when the sliding door 30 is in the open state. The power supply device supplies power to the light-emitting element 14 in response to, for example, the switching of a courtesy switch (not shown), and supplies power to the light-emitting element 14 from the initial timing of the opening operation before the sliding door 30 is fully open, causing the light-emitting element 14 to emit light.

[0034] (Operation of the Present Embodiment) Next, the operation of the wire harness 10 configured as described above will be described. For example, when the sliding door 30 is changed from a closed state to an open state, power is supplied from the power supply device to the light emitting member 14. Therefore, when the sliding door 30 is in the open state, the light emitting member 14 illuminates the area around the sliding door 30. This allows the user to easily get in and out of the vehicle, for example, even at night.

[0035] (Effects of the Present Embodiment) Next, the effects of the above-described embodiment are described below. (1) Because the wire harness 10 includes the light-emitting member 14 that illuminates the area around the sliding door 30, it is possible to reduce the number of electric wires compared to, for example, a configuration in which the light-emitting member 14 is provided on the sliding door 30. Specifically, for example, in a configuration in which the light-emitting member 14 is provided on the sliding door 30, an electric wire is required from the vehicle body 20 to the light-emitting member 14 provided on the sliding door 30. In contrast, because the wire harness 10 routed from the vehicle body 20 to the sliding door 30 includes the light-emitting member 14 midway, the path of the electric wire from the vehicle body 20 to the light-emitting member 14 is shortened. Therefore, it is possible to reduce the number of electric wires. Furthermore, as another effect, a structure for fixing the light-emitting member 14 to the vehicle body 20 and the sliding door 30 is not required.

[0036] (2) Because the door to which the wire harness 10 is connected is the sliding door 30, the effect of reducing the number of electric wires is greater than, for example, a side door, a back door, etc. that open and close by rotating around an axis. That is, the sliding door 30 tends to have longer electric wires from the vehicle body 20 to the door than a side door, a back door, etc., but because a portion of the wires can be shortened, the effect of reducing the number of electric wires is greater.

[0037] Furthermore, for example, in a configuration in which the sliding door 30 is provided with the light-emitting member 14, it is difficult to illuminate a desired position, such as below the boarding / exiting step 22, but it is possible to illuminate the desired position well. Also, for example, in a configuration in which the sliding door 30 is provided with the light-emitting member 14, the illuminated position continues to change during the opening and closing operation of the sliding door 30, but in contrast, it is possible to illuminate a fixed position, for example, after the initial opening operation. As a result, for example, visibility for the user is improved, making it easier for the user to get in and out.

[0038] (3) The wire harness 10 includes a plurality of separate bare elements 12 that cover the electric wire group 11, are arranged in parallel along the extension direction of the electric wire group 11, and are rotatably connected to each other. The light emitting member 14 is fixed to the separate bare elements 12, so that, for example, the position illuminated by the light emitting member 14 can be stabilized. For example, if the electric wire group 11 were simply covered with a corrugated tube, the wire harness 10 could bend freely at any position along the extension direction, and the bending pattern could change due to deterioration or the like, resulting in an unstable position illuminated by the light emitting member 14. In contrast, the plurality of separate bare elements 12 can maintain a constant bending pattern even when the sliding door 30 is repeatedly opened and closed, so that the position illuminated by the light emitting member 14 can be stabilized.

[0039] Furthermore, for example, if the wire group 11 were simply covered with a corrugated tube, the entire wire group 11 would tend to form a large arc when bent, which could lead to the wires penetrating into unwanted areas and ultimately contacting other components. In contrast, the multiple separate bare elements 12 can maintain a constant bending pattern, thereby reliably preventing contact with other components. Specifically, the wire harness 10 is prevented from protruding beyond the protrusion prevention line Z toward the vehicle body 20, thereby preventing a collision with the vehicle body 20.

[0040] (4) Each of the plurality of separate bear elements 12 has a U-shaped separate bear body 15 that is open on one side in a direction intersecting the extending direction of the electric wire group 11, and a bear cover 16 that is fixed to close the opening of the separate bear body 15. Since the light emitting member 14 is fixed to the bear cover 16, the special member to which the light emitting member 14 is fixed can be made smaller than, for example, a configuration in which the light emitting member 14 is fixed to the separate bear body 15. In other words, since the light emitting member 14 can be fixed by simply changing a small member, for example, manufacturing becomes easier and costs can be reduced.

[0041] (5) The light emitting member 14 is disposed inside the separate bear element 12 so as to illuminate the area around the sliding door 30 through the through-hole 16a of the bear cover 16, and is fixed to the bear cover 16 by the potting material 18, so that the light emitting member 14 is stably fixed. In addition, the potting material 18 can prevent the light emitting member 14 from being wet.

[0042] (6) The light-emitting member 14 is set to be disposed on the outer side of the vehicle body 20 than the step 22 for getting on and off when the sliding door 30 is fully open, and therefore can effectively illuminate a desired position, such as below the step 22. That is, for example, in a configuration in which the light-emitting member 14 is disposed in a position on the inner side than the outermost side of the step 22 for getting on and off in the vehicle body 20, the step 22 gets in the way, making it difficult to illuminate a desired position, such as below the step 22. In contrast, it is possible to effectively illuminate a desired position.

[0043] (Modifications) The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0044] In the above embodiment, the door to which the wire harness 10 is connected is the sliding door 30, but this is not limiting. For example, the door to which the wire harness 10 is connected may be a side door or a back door that opens and closes by rotating around an axis. This also makes it possible to reduce the number of electric wires compared to a configuration in which the light emitting member 14 is provided on the side door or the back door.

[0045] In the above embodiment, the wire harness 10 includes the plurality of separate bare elements 12 that cover the electric wire group 11, are arranged in parallel along the extending direction of the electric wire group 11, and are rotatably connected to each other. However, the present invention is not limited to this. For example, the wire harness may include the electric wire group 11 covered by a corrugated tube, and the light emitting member 14 may be provided on the corrugated tube.

[0046] In the above embodiment, the light emitting member 14 is fixed to the bear cover 16. However, this is not limitative. For example, the light emitting member 14 may be fixed to the separate bear main body 15.

[0047] In the above embodiment, the light emitting member 14 is disposed inside the separate bare element 12 and fixed to the bare cover 16 by the potting material 18, but this is not limiting. For example, the light emitting member 14 may be fixed to the outside of the separate bare element 12. Furthermore, for example, the light emitting member 14 may be fixed to the separate bare element 12 by a fixing structure other than the potting material 18.

[0048] In the above embodiment, the light emitting member 14 is set to be disposed on the outer side of the vehicle body 20 than the step 22 for getting in and out when the sliding door 30 is in the fully open state, but this is not limited to this. For example, the light emitting member 14 may be set to be disposed entirely in a position on the vehicle body 20 that is more inward than the outermost part of the step 22 for getting in and out.

[0049] In the above embodiment, the base cover 16 has the through-hole 16a as a light-transmitting portion. However, this is not limited to this, and the through-hole 16a may be replaced with another light-transmitting portion that can transmit light. For example, the base cover 16 may be configured to have a light-transmitting portion by two-color molding a lens in a portion corresponding to the through-hole 16a. Furthermore, for example, the base cover 16 may be configured to have a light-transmitting portion by molding all or part of the base cover 16 from a transparent resin material. Note that if the light-transmitting portion is the through-hole 16a, the light-transmitting portion can be more easily provided than other light-transmitting portions.

[0050] In the above embodiment, the rubber boot 13 has the rubber through-hole 13a as the rubber boot-side light-transmitting portion. However, this is not limited thereto, and the rubber through-hole 13a may be replaced with another rubber boot-side light-transmitting portion that can transmit light. For example, the rubber boot 13 may be configured to have a rubber boot-side light-transmitting portion by providing a thin film portion that can transmit light in a portion corresponding to the rubber through-hole 13a. Furthermore, the rubber boot 13 may be configured to have a rubber boot-side light-transmitting portion by molding all or part of the rubber boot 13 from transparent silicone or rubber. Note that if the rubber boot-side light-transmitting portion is the rubber through-hole 13a, the rubber boot-side light-transmitting portion can be more easily provided than if another rubber boot-side light-transmitting portion were used.

[0051] In the above embodiment, the plurality of separate bear elements 12 are of two types, the first separate bear element 12A and the second separate bear element 12B, which have different rotatable angles, but are not limited to this. For example, the plurality of separate bear elements 12 may be of a single separate bear element 12 with a fixed rotatable angle, or may be of three or more types of separate bear elements 12 with different rotatable angles.

[0052] In the above embodiment, the wire harness 10 is configured to include one light emitting member 14. However, the present invention is not limited to this and may be configured to include a plurality of light emitting members 14. For example, the light emitting member 14 may be fixed to two or three separate bare elements 12.

[0053] In the above embodiment, the wire harness 10 includes the rubber boot 13. However, the wire harness 10 is not limited to this and may be configured without the rubber boot 13. That is, the plurality of separate bare elements 12 may be configured to be exposed to the outside.

[0054] In the above embodiment, the light emitting member 14 is an LED board on which an LED element is mounted. However, the present invention is not limited to this. For example, the light emitting member 14 may be another type of light bulb or the like.
