Description

Technical Field

[0001] The invention relates to a wiring harness and a power supply device having the wiring harness, and belongs to the field of vehicle accessories and power supply. Background Art

[0002] Wire harnesses are indispensable in industry. Due to the environment in which they are used and their own softness, they are easily damaged when exposed to the outside. Therefore, protective structures such as sleeves are needed to store the wire harnesses and protect them. At the same time, the flexibility of the wiring harness layout and guidance must be ensured. In addition to the protection function (external protective cover), the wire harness protection structure also needs to support the wire harness and ensure a certain wire harness guidance function (internal skeleton structure).

[0003] In the vehicle field, the automotive sliding door system has many advantages over the traditional hinged revolving door due to its unique opening method, and is now increasingly favored by customers. The side sliding door design is used for the luxury passenger MPV, and the electric sliding door technology requires a sliding door power supply device that can provide continuous, stable and safe power supply. The bending control component in the power supply device is an indispensable component to ensure the movement of the sliding door.

[0004] As mentioned above, the wiring harness of the existing sliding door power supply device is generally provided with a tow chain structure that is combined with each other inside, and then a protective cover is put on the outside. However, for this existing wiring harness, there are many parts, the manufacturing cost is high, and the durability of the whole is reduced due to the different durability strengths of different parts. In addition, the tow chain structure has many parts that are combined with each other, and the number of wire loops that can be accommodated per unit area is limited, so it is easy to generate noise when the vehicle is running, and the volume needs to be expanded to accommodate a large number of wiring harnesses. Moreover, the adjacent gaps in the tow chain skeleton structure are large and there are many sharp shapes that the internal wiring harness can touch, which will wear the wires during the bending process, break the wires and cause circuit breakage, affecting the flexure performance of the device, and the wiring harness is arranged in a relatively chaotic manner. Summary of the invention

[0005] In order to solve the above-mentioned problems in the prior art, the present invention provides a wiring harness and a safe, stable and continuous power supply device having the wiring harness, which reduces manufacturing costs, improves production efficiency and durability, and can reduce components, extend life and solve the noise problem caused by too many components. It can also increase the capacity of wires within a limited accommodation space, and can also reduce wear of wires during bending and improve the wiring harness arrangement.

[0006] A first aspect of the present invention provides a wire harness routed from a vehicle body to a sliding body, the wire harness comprising: an electric wire; and a bending control component. The bending control component comprises: a frame portion extending in the length direction of the electric wire to control the bending of the electric wire, and a flexible sleeve portion extending smoothly along the length direction of the electric wire and integrally formed with the frame portion to cover the frame portion inside the sleeve portion.

[0007] According to the wiring harness with the above structure, the skeleton part for controlling the bending of the wires is integrally formed with the external sleeve part. There is no need to assemble the multiple internal drag chains and then insert them into the protective cover for manufacturing as in the prior art. Only the integral forming step is required, thereby reducing costs, improving production efficiency, and improving the overall durability of the product. In addition, since the skeleton part and the sleeve part are integrally formed, the friction between the skeleton part and the sleeve part is greatly reduced, the durability is improved and the noise is suppressed, and the requirements for the manufacturing accuracy of the skeleton part are also reduced. Even if there are burrs, since it is integrally formed with the sleeve part, the burrs are formed in the thickness of the sleeve, so the impact on the sleeve part is limited, thereby improving the qualified rate of the product. Moreover, the sleeve part of the present invention extends smoothly, and does not adopt the traditional corrugated tube-shaped sheath, so the overall aesthetics is improved.

[0008] Preferably, in the wiring harness of the first aspect, the skeleton portion is constructed by a plurality of joint portions which are relatively independently arranged and arranged along the electric wires, and each of the joint portions of the skeleton portion has an I-shaped cross-sectional shape, so that the joint portion is formed with a first recess and a second recess which open toward different directions and a support wall which serves as a common bottom of the first recess and the second recess, the electric wires are accommodated in the first recess and the second recess, a hole portion is provided in the support wall, the hole portion extends along a height direction of the support wall, the hole portion is a through hole which penetrates the support wall or a blind hole which does not penetrate the support wall, and a part of the sleeve portion which is integrally formed with the skeleton portion is embedded in the hole portion.

[0009] According to the wiring harness with the above structure, the skeleton part is constructed by a plurality of joint parts which are relatively independently arranged and arranged along the wires, so the bending degree or bending condition of the wires in multiple directions can be controlled by the shape or arrangement of the desired joint parts. The joint part is arranged to have an I-shaped cross-sectional shape, so that a first recess and a second recess with different openings are formed as a wire laying space for accommodating the wires, and the wires can be laid out in layers and arranged in an orderly manner. Moreover, by utilizing the hole part arranged in the supporting wall, a part of the sleeve part which is integrally formed with it is embedded in the hole part, which improves the bonding strength between the sleeve part and the joint part, and the sleeve part is difficult to be peeled off from the joint part. Even if each joint part is completely independently arranged from each other, the joint part will not be in a tangent, and the reliability is high. In addition, the joint parts with I-shaped cross-sections which are independently arranged from each other can be manufactured smoothly, and there is no sharp part that rubs the wires. Therefore, even if the wiring harness is often bent, it will not be scratched by the sharp part, which can protect the wires, improve reliability, and form a stable electrical structure. Moreover, since it is an I-shape, the depth and size of the two recesses can be controlled to meet the required harness trajectory. Moreover, the I-shape allows both sides to be rigidly controlled, so that the harness bending trajectory can be controlled from both sides.

[0010] Preferably, in the wiring harness of the first aspect, the skeleton portion is constructed by a plurality of joint portions which are relatively independently arranged and arranged along the electric wires, and each of the joint portions of the skeleton portion has an I-shaped cross-sectional shape, so that the joint portion is formed with a first recess and a second recess opening toward different directions and a support wall serving as a common bottom of the first recess and the second recess, the electric wires are accommodated in the first recess and the second recess, and each of the joint portions is formed with a protrusion protruding outward and / or a recessed portion recessed inward on an outer surface on one side of the support wall in the height direction and on another outer surface on the other side of the support wall in the height direction, the protrusion extends into the sleeve portion integrally formed with the skeleton portion, and a part of the sleeve portion is integrally embedded in the recess.

[0011] By using the wiring harness having the above structure, instead of providing a hole in the support wall, a protrusion or / and a recess can be provided on the outer surface of the joint part facing the sleeve part to achieve an integral combination with the sleeve part. The concave and convex parts can also be configured in a wedge shape or a hook, thereby further improving the integral combination strength of the joint part and the sleeve part.

[0012] Preferably, in the wiring harness of the first aspect, the skeleton portion is constructed by a plurality of joint portions which are relatively independently arranged and arranged along the wires, and each of the joint portions of the skeleton portion includes: one or more support walls; and one or more partition walls extending from the support walls in a direction intersecting the support walls, and the wires are respectively accommodated in the wire laying space divided by the support walls and the partition walls.

[0013] According to the wiring harness with the above structure, the joint part can be divided into a plurality of wire laying spaces for accommodating the wires by the horizontally and vertically staggered support walls and partition walls. The position and size of each wire laying space can be adjusted according to actual requirements by adjusting the number and arrangement position of the support walls or partition walls to meet various wire arrangement needs.

[0014] Preferably, in the wiring harness of the first aspect, a hole portion is provided in at least one of the support walls, the hole portion extends along the height direction of the support wall, the hole portion is a through hole penetrating the support wall or a blind hole not penetrating the support wall, and a part of the sleeve portion integrally formed with the joint portion is formed in the hole portion.

[0015] According to the wiring harness having the above structure, similar to the supporting wall of the joint part of the aforementioned I-shaped cross section, a portion of the integrally formed sleeve part is embedded in the hole part by utilizing the hole part set in the supporting wall, thereby improving the bonding strength between the sleeve part and the joint part, and the sleeve part is difficult to be separated from the joint part. Even if each joint part is completely independently set, the joint part will not be in sync, and the reliability is high. In addition, the joint parts of the I-shaped cross section set independently of each other can be manufactured smoothly, and there are no sharp parts that rub the wires. Therefore, even if the wiring harness is often bent, it will not be scratched by the sharp parts, which can protect the wires and improve reliability.

[0016] Preferably, in the wiring harness of the first aspect, the surface of the partition wall facing the sleeve portion is formed with a protrusion protruding toward the sleeve portion and / or a recessed portion recessed inward, the protrusion extends into the sleeve portion integrally formed with the skeleton portion, and a part of the sleeve portion is integrally embedded in the recessed portion.

[0017] According to the wiring harness having the above structure, similar to the joint part of the I-shaped cross section, the joint part can be integrated with the sleeve part by providing a protrusion or a recessed part on the outer surface of the joint part facing the sleeve part. The concave and convex parts can also be configured in a wedge shape or a hook part, so that the strength of the integrated molding of the frame part and the sleeve part can be further improved.

[0018] Preferably, in the wiring harness of the first aspect above, each of the joint parts of the skeleton part includes a support wall and two side walls extending from both ends of the support wall to form a U-shape, and when the joint parts are aligned with each other and thus connected to each other, adjacent joint parts have gaps between them, and the gaps are filled with the material of the integrally molded sleeve part.

[0019] According to the wiring harness having the above structure, each joint has a U-shape and the gaps between them are filled with the material of the sleeve. The U-shape has a simple structure and no sharp corners, a simple manufacturing process, and no damage to the wires, and has high reliability.

[0020] In addition, instead of the U-shaped joints spaced apart from each other, the U-shaped joints can be connected to each other by supporting walls so that they can be relatively integrated while being relatively independently arranged, and can be more reliably integrally formed on the inner side of the sleeve and more reliably combined with the sleeve.

[0021] Preferably, according to the wiring harness of the first aspect, the skeleton portion is constructed of a flat elastic plate, the elastic plate extends in the length direction of the electric wire, and is integrally formed with the sleeve portion and embedded in the tube wall of the sleeve portion in such a way that the thickness direction of the elastic plate is consistent with the bending direction of the wiring harness.

[0022] According to the wiring harness having the above structure, a flat elastic plate is used instead of a plurality of joints to achieve control of the bending of the wires. At this time, the elastic plate integrally embedded in the tube wall of the sleeve portion provides a guiding track for the bending of the wires, thereby providing control over the bending of the wiring harness.

[0023] Preferably, in the wire harness of the first aspect, the thickness of one side of the elastic plate is greater than the thickness of the other side, and when the wire harness is laid from the vehicle body to the sliding body, one side of the elastic plate is the vehicle body side and the other side of the elastic plate is the sliding body side.

[0024] According to the wiring harness with the above structure, the thickness of the elastic plate structure is designed so that the thickness close to the vehicle body side is greater than the thickness close to the sliding body side, thereby ensuring that when the wiring harness is applied to the sliding body, the connecting portion close to the sliding body has a certain resilience, so that the wiring harness can bend more smoothly following the sliding of the sliding body.

[0025] A second aspect of the present invention provides a power supply device comprising: a wire harness according to the first aspect above; a vehicle body side unit that supports the wire harness on the vehicle body side; and a sliding body side unit that supports the wire harness on the sliding body side.

[0026] With the power supply device of the second aspect of the present invention having the above-mentioned structure, since it uses the wiring harness of the first aspect, the various technical effects of the wiring harness of the first aspect described above can also be achieved.

[0027] The third aspect of the present invention provides a method for manufacturing the wire harness of the first aspect, comprising: manufacturing the bending control component; and inserting the wire into the inner space of the bending control component. The bending control component is manufactured by the following steps: forming the skeleton part by injection molding; and fixing the injection-molded skeleton in the middle of a mold, and injecting a flexible material for secondary molding to form the sleeve part, so that the skeleton part and the sleeve part are integrally molded.

[0028] The wiring harness is manufactured by the above method, and the wiring harness includes an integrally formed skeleton part and a sleeve part. Therefore, there is no need to assemble multiple internal drag chains and then insert them into a protective cover as in the prior art. Only the integral forming step is required, thereby reducing costs, improving production efficiency, and improving the overall durability of the product. In addition, since the skeleton part and the sleeve part are integrally formed, the friction between the skeleton part and the sleeve part is greatly reduced, the durability is improved and the noise is suppressed, and the requirements for the manufacturing accuracy of the skeleton part are also reduced. Even if there are burrs, since it is integrally formed with the sleeve part, the burrs are formed in the thickness of the sleeve, so the impact on the sleeve part is limited, thereby improving the qualified rate of the product. Moreover, the sleeve part of the present invention extends smoothly, and does not use a traditional corrugated tube-shaped sheath, so the overall aesthetics is improved.

[0056] Hereinafter, the technical solution of the present invention will be more clearly illustrated by describing specific embodiments of the present invention with reference to the accompanying drawings.

[0057] It should be noted that the drawings of the present invention are only schematic diagrams for the purpose of clearly showing the parts related to the scheme of the present invention, and some non-essential parts that may exist are not shown. Therefore, these drawings should not be understood as limiting the present invention, and they may be different from the actual structure when used. In addition, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", etc. that may appear in the following description to indicate the orientation or position are for the purpose of convenience of explanation and are not restrictive. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0058] First embodiment

[0059] The wire harness of the present invention is used to be laid from the vehicle body to the sliding body, so as to realize the transmission of power and / or signal from the vehicle body side to the sliding body side. The sliding body is, for example, a sliding door, a seat, etc. When the sliding body slides, the wire harness bends with the sliding of the sliding body. Figure 1 to Figure 4 A wiring harness according to a first embodiment of the present invention is shown, wherein: Figure 1 is a schematic perspective view of a wire harness according to a first embodiment of the present invention, in which one end portion is shown with a sleeve portion removed and drawing of electric wires is omitted; Figure 2 is a schematic perspective view of the wire harness according to the first embodiment of the present invention viewed from another angle, in which one end portion is shown with the sleeve portion removed and drawing of the electric wires is omitted; Figure 3 yes Figure 1 an AA cross-section of the wiring harness; and Figure 4 yes Figure 1 BB section view of the wiring harness.

[0060] like Figure 1 As shown, the wire harness 100 according to the first embodiment of the present invention (see Fig. 9 ) includes an electric wire (not shown) and a bending control component 1. The bending control component 1 may include: a skeleton part 10, which is constructed by a plurality of relatively independently arranged joint parts 20, and the plurality of joint parts 20 are arranged along the length direction of the electric wire to control the bending of the electric wire; and a flexible sleeve part 30, the sleeve part 30 smoothly extends along the length direction of the electric wire, and is integrally formed with the skeleton part 10, so that the plurality of joint parts 20 constituting the skeleton part 10 are covered on the inner side of the sleeve part 30. The sleeve part 30 may be made of a soft rubber material, but is not restrictive, and may be other flexible materials. The skeleton part 10 may be made of materials such as resin.

[0061] According to the wire harness of the first embodiment of the present invention having the above structure, compared with the conventional technology of first assembling a plurality of drag chains and then inserting the assembled drag chain assembly into a protective cover to manufacture the bending control component, the relatively independent plurality of joint parts 20 of this embodiment are integrally formed with the external sleeve part 30, eliminating the step of mutual assembly, and the joint part 20 itself can have a simpler structure because it eliminates the assembly part assembled with other joint parts, so the wire harness of this embodiment reduces the cost, improves the production efficiency, and improves the overall durability of the product. In addition, since the plurality of joint parts 20 are integrally formed with the sleeve part 30, the friction between the joint part 20 and the sleeve part 30 is greatly reduced, the durability is improved, and the noise generated by the collision between the parts when the wire harness is bent is suppressed, and the manufacturing accuracy requirements for the joint part 20 are also reduced, even if there are burrs, since it is integrally formed with the sleeve part 30, the burrs are formed in the thickness of the sleeve, so the influence on the sleeve part is also limited, so the qualified rate of the product is also improved.

[0062] As shown in the figure, in the wire harness 100 (see Fig. 9 ), each joint portion 20 of the skeleton portion 10 has an I-shaped cross-sectional shape, so that the joint portion 20 is formed with a first recess 23 and a second recess 24 with openings facing different directions and a support wall 21 as a common bottom of the first recess 23 and the second recess 24, and the wires can be accommodated in the first recess 23 and the second recess 24. In this embodiment, although not shown, it can be understood that the number of wires accommodated in the first recess 23 and the second recess 24 is not limited, the specifications are not limited, or the wires are accommodated in only one of the recesses; in addition, the wires can be accommodated in an unbundled state, or in a bundled state, or in a state where a part of them is bundled and the rest is not bundled, or in a state where they are bundled into multiple bundles. There can be a gap between adjacent joint portions 20 of the skeleton portion 10, and the size of the gap can be adjusted as needed.

[0063] like Figure 1 to Figure 4 As shown, in the wire harness of this embodiment, a hole portion 25 is provided in the support wall 21 of each joint portion 20 of the skeleton portion 10, and the hole portion 25 extends along the height direction of the support wall to form a through hole penetrating the support wall. Figure 1 and Figure 2 As shown, in this embodiment, three holes 25 are provided in each supporting wall 21, the middle one is an oblong hole, and the two holes on both sides are round holes. Since the frame part 10 and the sleeve part 30 are integrally formed, a part of the material or thickness of the sleeve part 30 is embedded in the hole 25, and the sleeve part 30 and the frame part 10 are firmly fixed together.

[0064] In addition, those skilled in the art will appreciate that the number, arrangement and shape of the hole portions 25 shown in the figure are merely examples and are not restrictive. For example, the hole portion 25 is not necessarily a through hole, but may be a non-through blind hole, the shape of the hole portion 25 may be other shapes besides an oblong or a circle, the number of the hole portions 25 may be 1, 2 or more than 3, and the position of the hole portion 25 is not limited to the figure and may be arranged as required.

[0065] In this embodiment, if Figure 3 and Figure 4 As shown, the depths (degree of depression) of the first recess 23 and the second recess 24 of the joint 20 as the wire laying space are different, and the first recess 23 is deeper than the second recess 24. This is because: by controlling the depths and sizes of the two recesses, the required harness trajectory can be met, and both sides of the first recess and the second recess can be rigidly controlled, so that the harness bending trajectory can be controlled from both sides. However, this is not restrictive, and the first recess and the second recess can also have the same depth.

[0066] In addition, if Figure 1 and Figure 2 As shown, the upper and lower side walls of the I-shaped joint portion 20 may gradually decrease in width toward the end portion, and the degree to which the end widths of the respective side walls constituting the first recess and the second recess gradually decrease may be different, so that the gap between adjacent joint portions may gradually increase toward the outside. Figure 2 When the wire harness is bent to a certain extent in a second direction (for example, in a downward direction) opposite to the first direction, the side walls of the adjacent joints abut against each other, thereby limiting the bending of the wire harness. Figure 2 When the wire harness is bent to a certain extent in the upward direction, the side walls of the adjacent joints abut against each other, thereby limiting the bending of the wire harness. By adjusting the degree to which the width of the end of each side wall constituting the first recess and the second recess of the joint gradually decreases, the degree of control over the bending of the wire harness can be adjusted.

[0067] According to the wiring harness 100 of the above structure of the present embodiment, each joint part 20 of the skeleton part 10 is set to have an I-shaped cross-sectional shape, so that a first recess 23 and a second recess 24 with different opening directions are formed as a wire laying space for accommodating the wires, and the wires can be laid out in layers with the support wall 21 as intervals, and the arrangement is orderly. Moreover, by using the hole part 25 set in the support wall 21, a part of the sleeve part 30 integrally formed with it is embedded in the hole part 25, which improves the bonding strength between the sleeve part 30 and the joint part 20, and the sleeve part 30 is difficult to be separated from the joint part 20. Even if each joint part 20 is completely independently set, the joint part 20 will not be in a tangent, and the reliability is high. In addition, the joint parts 20 with an I-shaped cross-section set independently of each other can be manufactured smoothly, and there is no sharp part that rubs the wires. Therefore, even if the wiring harness is often bent, it will not be scratched by the sharp part, which can protect the wires and improve reliability.

[0068] In addition, instead of the hole portion shown in the figure, each joint portion may also be formed with a protrusion protruding outward and / or a recessed portion recessed inward on an outer surface on one side of the support wall in the height direction and on the other outer surface on the other side of the support wall in the height direction, the protrusion extending into a sleeve portion integrally formed with the skeleton portion, and a part of the sleeve portion integrally embedded in the recessed portion.

[0069] By using the wiring harness having the above structure, instead of providing a hole in the support wall, a protrusion or / and a recess can be provided on the outer surface of the joint part facing the sleeve part to achieve an integral combination with the sleeve part. The concave and convex parts can also be configured in a wedge shape or a hook, thereby further improving the integral combination strength of the joint part and the sleeve part. In addition, the hole and the concave and convex parts can also be provided at the same time.

[0070] Second embodiment

[0071] Figures 5 to 7 shows a schematic perspective view of a wire harness according to a second embodiment of the present invention; Figure 6 yes Figure 5 CC section view of the wiring harness; Figure 7 yes Figure 5 DD cross-section of the wiring harness.

[0072] The wire harness of the second embodiment is substantially the same as the wire harness of the first embodiment, and also includes electric wires (not shown) and a bending control component 1 having an integrally formed frame portion 10 and sleeve portion 30. The wire harness of the second embodiment is different from the first embodiment in the joint portions 20 of the frame portion 10.

[0073] like Figure 5 to Figure 7As shown, the relatively independently arranged multiple joint parts 20 of the skeleton part 10 of the bending control component 1 of the second embodiment do not have an I-shaped cross-sectional shape, but have a U-shaped cross-sectional shape. That is, the joint part 20 can have a support wall 21 and two side walls 22, 22 extending from both sides of the support wall 21, so as to have a U-shaped shape, and the support wall 21 and the two side walls 22 surround a wire laying space 27 similar to the concave part of the first embodiment. In addition, the support walls 21 of each joint part 20 are not limited to being separated from each other, but can also be arranged to be connected to each other, that is, the support wall 21 of each joint part 20 can be a common support wall, and the two side walls extend from the support wall at predetermined intervals, thereby forming relatively independent joint parts 20.

[0074] like Figure 5 As shown, for the wire harness of the second embodiment, the two end portions of the skeleton portion 10 may be provided with protruding positioning edges, which are positioned outside the two ends of the sleeve portion 30 to assist in the connection between the wire harness and the vehicle body and the sliding body. Figure 6-7 As shown, a protruding protrusion 26 is formed on the surface of the side walls 22, 22 of each joint part 20 of the skeleton part 10 facing the sleeve part 30. The protrusion 26 extends into the sleeve part 30 integrally formed with the skeleton part 10, and is tightly integrated and fixed with the sleeve part 30 to prevent the sleeve part 30 from detaching from the joint part 20.

[0075] In this embodiment, two protrusions 26 are shown, but this is not restrictive. The number of protrusions 26 can be other numbers, such as 1 or more than 2. In addition, the protrusion 26 can be across the entire surface of the side wall 22 along the extension direction of the wire, or can be formed intermittently or partially. In addition, instead of the protrusion 26, a concave recessed portion can be formed on the surface of the side wall 22, 22 facing the sleeve portion 30, so that a part of the sleeve portion 30 is integrally embedded in the recessed portion, or the protrusion and the recessed portion are set at the same time. In addition, the shape of the protrusion 26 is not limited to the shape shown in the figure, and can be set to a wedge shape or a T-shaped hook shape, so that the corresponding concave and convex fit between the protrusion or the recessed portion and the sleeve portion 30 is more reliable, and it is more difficult to make the sleeve portion 30 detach from the skeleton portion 10, thereby improving the bonding strength of the skeleton portion and the sleeve portion.

[0076] In addition, although not shown, similarly to the first embodiment, a hole portion capable of embedding the material of the sleeve portion 30 may be provided in the support wall 21 of the joint portion 20 of the second embodiment, thereby enhancing the integral bonding strength between the sleeve portion 30 and the joint portion 20 .

[0077] In the second embodiment, when the harness is in the first direction ( Figure 5When the wire harness is bent to a certain extent in the direction of the opening of the U-shape, the side walls of the adjacent joints abut against each other and cannot bend further. When the wire harness is bent in a second direction opposite to the first direction, the bending of the wire harness is not restricted. Therefore, the bending of the wire harness can be controlled by the bending control component.

[0078] The second embodiment of the present invention has been described above with reference to the accompanying drawings. Similar to the first embodiment, the wire harness of this embodiment reduces costs, improves production efficiency, and enhances the overall durability of the product by utilizing a bending control component composed of an integrally formed skeleton portion 10 and a sleeve portion 30. At the same time, it suppresses the noise generated by collisions between components when the wire harness is bent and improves the qualified rate of the product. In addition, since the wires can be laid in the wire laying space, the wires can be arranged in an orderly manner, thereby enhancing the aesthetics.

[0079] Third embodiment

[0080] Figure 8 A wire harness according to a third embodiment of the present invention is shown, in which only the sleeve portion is illustrated and other components are omitted.

[0081] The third embodiment differs from the first and second embodiments only in the arrangement of the skeleton portion. Figure 8 As shown, instead of the skeleton portion composed of multiple joint portions in the first and second embodiments, the skeleton portion of the bending control component of the wiring harness of the third embodiment is constructed by a flat elastic plate 40, extending in the length direction of the wire, and is integrally embedded in the tube wall of the sleeve portion 30 in such a way that the thickness direction of the elastic plate is consistent with the bending direction of the wiring harness.

[0082] According to the wire harness having the above structure, the skeleton part is formed by an elastic plate part which is very simple in structure and very easy to obtain instead of each joint part having a relatively complex structure. The elastic plate part can control the bending degree and bending shape of the wire due to its elasticity. The elastic plate which is integrally embedded in the tube wall of the sleeve part provides a guiding track for the bending of the wire, and can provide the ability to control the bending of the wire harness.

[0083] In addition, in the third embodiment, the elastic plate 40 buried in the tube wall material of the sleeve portion 30 can be designed so that the thickness on one side is greater than the thickness on the other side, and when the wiring harness is laid from the body of the vehicle to the sliding body, one side of the elastic plate, i.e., the side with a larger thickness, is the body side, and the other side of the elastic plate, i.e., the side with a smaller thickness, is the sliding body side.

[0084] According to the wiring harness with the above structure, the thickness of the elastic plate structure is designed so that the thickness close to the vehicle body side is greater than the thickness close to the sliding body side, thereby ensuring that when the wiring harness sleeve portion is applied to the sliding body, the connecting portion close to the sliding body side has a certain resilience, so that the wiring harness can bend more smoothly following the sliding of the sliding body.

[0085] The first to third embodiments of the present invention have been described above in conjunction with the accompanying drawings. However, the joint portion of the wire harness of the present invention, especially the skeleton portion of the bending control component, is not limited to the I-shaped or U-shaped shape in the embodiments, but can be appropriately deformed. For example, a partition wall can be provided in the first recess and the second recess of the I-shaped joint portion, so that the cross-sectional shape of the joint portion becomes a W-shaped shape, and the partition walls of the first recess and the second recess may not be aligned with each other, and the number of partition walls may not be limited to 1. For another example, another supporting wall can be provided in the I-shaped joint portion, so that the cross-sectional shape becomes similar to a tic-tac-toe. For another example, in the U-shaped joint portion, a similar partition wall and / or a similar additional supporting wall can also be provided. In this structure, more wire laying spaces are divided by the partition walls and the supporting walls.

[0086] That is, each of the joints of the skeleton part may include: one or more supporting walls; and one or more partition walls extending from the supporting walls in a direction intersecting the supporting walls, and the wires are respectively accommodated in the wire laying spaces divided by the supporting walls and the partition walls. Therefore, the joint part can be divided into a plurality of wire laying spaces for accommodating wires by the supporting walls and the partition walls staggered horizontally and vertically, and the position and size of each wire laying space can be adjusted by adjusting the number and arrangement position of the supporting walls or the partition walls according to actual requirements to meet various wire arrangement requirements.

[0087] Besides this, it is also possible that the joint comprises only one supporting wall without partition walls or side walls.

[0088] Fig. 9 FIG. 2 shows a power supply device 200 of the present invention. The power supply device 200 adopts Figure 1-8 The wiring harness of each embodiment is shown.

[0089] The power supply device 200 is capable of transmitting power and / or transmitting signals between the vehicle body and a sliding body such as a sliding door or a seat. In this embodiment, the sliding body is illustrated as a sliding door. The power supply device 200 includes: the wiring harness 100 in any one of the first to third embodiments, which is to be laid from the vehicle body to the sliding door; a vehicle body side unit 50, which supports the sleeve portion of the wiring harness 100 on the vehicle body side; and a sliding body side unit 60, which supports the sleeve portion on the sliding door side.

[0090] Fig. 9The dotted line portion is the closed state of the sliding door, and the solid line portion is the open state of the sliding door. The two ends of the integrally formed sleeve portion are respectively connected to the body side unit 50 as a relatively fixed portion (passive component, which can actually be applied to the body end and powered by an external power supply) and the sliding body side unit 60 as a relatively movable portion (active component, which can actually be applied to the sliding door end and connected to the sliding door power supply), wherein rotating shafts can be set on both sides to maintain the multi-angle requirements of the connection part (it should be noted that rotating shafts are not necessarily required on both sides, and it is also feasible to have no rotating shafts on both sides and keep them fixed, and the curvature of the sleeve portion of the wiring harness itself can also realize the opening and closing of the sliding door).

[0091] In the power supply device 200 of the present embodiment, since the connection between the vehicle body and the sliding body adopts the wiring harness of the present embodiment, the various technical effects mentioned above can be achieved, and the power supply device is safe, stable and continuous.

[0092] Next, the manufacturing method of the wire harness 100 of the first to third embodiments will be described, including: manufacturing the bending control component 1; and inserting the wires into the inner space of the bending control component 1. The steps of manufacturing the bending control component 1 mainly include: forming the skeleton part 10 by injection molding; and fixing the injection-molded skeleton part 10 in the middle of the mold, and injecting a flexible material for secondary molding to form the sleeve part 30, so that the skeleton part 10 and the sleeve part 30 are integrally molded.

[0093] After the manufacturing of the wire harness is completed through the above steps, both ends of the entire wire harness 100 can be installed on the vehicle body side unit 50 and the slider side unit 60 respectively, so that the power supply device 200 is completed.

[0094] Using the above method, the wiring harness includes an integrally formed skeleton portion and a sleeve portion, so there is no need to assemble multiple internal drag chains and then insert them into a protective cover for manufacturing as in the prior art. Only the integral forming step is required, thereby reducing costs, improving production efficiency, and improving the overall durability of the product. In addition, since the skeleton portion and the sleeve portion are integrally formed, the friction between the skeleton portion and the sleeve portion is greatly reduced, durability is improved, noise is suppressed, and the requirements for the manufacturing accuracy of the skeleton portion are also reduced. Even if there are burrs, since it is integrally formed with the sleeve portion, the burrs are formed in the thickness of the sleeve, so the impact on the sleeve portion is limited, thereby improving the qualified rate of the product. Moreover, the sleeve portion of the present invention extends smoothly, and does not use a traditional corrugated tube-shaped sheath, so the overall aesthetics is improved.

[0095] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
