[0002] With the continuous progress of automobile technology, the functional needs of users for automotive glass are increasingly diversified, especially the demand for ride comfort, privacy and personalized display has significantly increased. In order to realize these advanced functions, the automotive glass is subdivided into multiple small blocks, each of which can be independently controlled to display different content or adjust the transparency, thereby meeting the needs of sun protection, energy saving and improving the driving experience.

In order to simplify the connection, these wires are usually integrated into a bundle, as shown in Figure 2 、 Figure 3 and Figure 4 However, due to the space constraints of vehicle design, door styling and other internal components (such as limiters, latching locks, etc.), the distance between the power supply interface at the end of the harness and the power receiving interface at the end of the window glass is often far. Therefore, this bundle not only needs to be long enough to connect the two interfaces, but also needs to move with the lifting of the window glass, and needs to be bent for installation to adapt to the space inside the door. This installation method has the following problems:

[0004] 1. Large space occupation, as shown in Figure 2 The harness structure is integrated by single or multiple layers of wires, resulting in an excessively large size in a single direction, as shown in Figure 3 The harness is a circular structure integrated by multiple wires, with a large diameter. The above integration makes it difficult to arrange other components inside the door;

[0005] 2. The wire is prone to breakage, as shown in Figure 3 and Figure 4 Since the harness is a circular structure integrated by multiple wires, the outer wires are prone to breakage due to friction and bending during the movement of the harness with the glass lifting. INVENTION CONTENTS

[0039] Please refer to Figure 1 A multi-conductor integrated wire harness, comprising: N insulated conductors 111; the first wire harness 11 is integrated with X conductors; the second wire harness 12 is integrated with Y conductors; the third wire harness 13 is integrated with Z conductors; wherein N=X+Y+Z, the first wire harness 11, the second wire harness 12 and the third wire harness 13 are arranged in sequence and side by side to form a flat wire harness 1, and the flat wire harness 1 is provided with a protection layer 14 on the outside. Specifically, the number N of regions of the vehicle window glass is divided into the same number of conductors 111. Preferably, 6≤N≤12, Y≥X and Y≥Z, X and Z are not equal to zero. Preferably, X≥2, and Z≥2. The number of conductors in each wire harness is distributed as follows:

[0040] N and X, Y and Z distribution table

[0041] N (number) 6 7 8 9 10 11 12 X (number) 2 2 3 3 3 4 4 Y (number) 2 3 3 3 4 4 4 Z (number) 2 2 2 3 3 3 4 illustration Figure 1 Figure 8 Figure 9 Figure 10

[0042] Figure 1 、 Figure 8 、 Figure 9 and Figure 10 respectively represent the layout diagram when the number of conductors 111 is 6, 7, 8 and 12. The protection layer 14 is formed by polyether TPU material, which has good weather resistance and oil resistance and is not easy to break.

[0043] The wire harness of the utility model is flat, divided into three small bundles, avoiding N conductors integrated into a circular wire harness. The circular wire harness not only has a large volume, but also has a large difference in bending radius between the inner conductor and the outer conductor when bending, which can easily break the outer conductor and wear the outer protection layer. This wire harness structure avoids the disadvantages of single-layer or multi-layer arrangement of conductors, which causes the size of the wire harness in a single direction to be too large, which is not conducive to the space layout of the vehicle door.

[0044] As shown in the column Figure 3 , a plurality of conductors are integrated into a circular wire harness, as shown in Figure 4 Figure 3 ​(Cross-sectional view of position AA), the bending radii from the inside to the outside are R1, R2, R3, and R4, respectively. The radius of R1 is R, then the radius of R2 is R+d+K, the radius of R3 is R+2d+2K, and the radius of R4 is R+3d+3K, where d is the outer diameter of the conductor and K is the gap between the conductors. From... Figure 4 It can be seen that when bending, the bending radius of the inner and outer conductors differs too much, making the outer conductor prone to breakage.

[0045] Please see Figure 5 Furthermore, the multi-wire integrated harness also includes a first wire segment 2, a bushing 3, a fixed rotary joint 4, a second wire segment 5, a first connector 6, and a second connector 7. One end of the flat wire harness 1 is installed on the bushing 3, and the other end is installed on the fixed rotary joint 4. One end of the first wire segment 2 is installed on the bushing 3, and the other end is connected to the first connector 6. One end of the second wire segment 5 is installed on the fixed rotary joint 4, and the other end is connected to the second connector 7. The first connector 6, the flat wire harness 1, and the second connector 7 are electrically connected. Specifically, the first wire segment 2 and the second wire segment 5 are conventional circular wire harnesses integrated from N wires. The outer diameter of the wires in the first wire segment 2 and the second wire segment 5 are equal and larger than the outer diameter of the wires in the flat wire harness 1. By changing the outer diameter of the wires, the volume of the flat wire harness 1 can be minimized while meeting electrical requirements, thus saving space in the vehicle window arrangement. The conductors of the first conductor segment 2 and the flat wire harness 1 are first electrically connected by welding. The welding area of ​​each conductor 111 is covered with insulating cloth. Then, the first conductor segment 2 and the flat wire harness 1 are connected by injection molding through a mold to enhance their strength. After being inserted into the bushing 3, it is installed and connected to the first plug-in interface 6. Similarly, the conductors of the second conductor segment 5 and the flat wire harness 1 are installed in the fixed rotary joint 4.

[0046] Please see Figure 5 and Figure 6 Furthermore, the upper end face of the bushing 3 is provided with an outlet 31 that matches the outer diameter of the first conductor segment 2, allowing the first conductor segment 2 to rotate within a small angle range in the bushing 3. This prevents the flat wire harness 1 from getting stuck due to the fixed connection between the first connector 6 and the external interface when moving, reduces the pulling effect of the flat wire harness 1 on the first conductor segment 2 during lifting and lowering, and extends the service life of the flat wire harness 1. With this structure, the injection molding area is located in the bushing 3, which protects the injection molding area.

[0047] Please see Figure 5 and Figure 6Further, the outer wall of one side of the bushing 3 is provided with an opening 32 matched with the flat wire bundle 1. Specifically, the bushing 3 is in the shape of a cylinder as a whole, and the opening 32 is arranged on one side of the lower end. The width of the opening 32 is equal to the thickness of the flat wire bundle 1, and the length of the opening 32 is matched with the length of the flat wire bundle 1, so as to restrict the free swing range of the flat wire bundle 1 in the opening 32, i.e. to restrict the wire outlet of the flat wire bundle 1.

[0048] Please refer to Figure 5 and Figure 6 Further, the upper end of the opening 32 is provided with an elastic sheet 33, and the lower end of the elastic sheet 33 is provided with a pressing table 331. One side of the outer surface of the flat wire bundle 1 is provided with a sliding groove 15 matched with the pressing table 331. In use, the pressing table 331 is in abutment with the inner wall of the sliding groove 15, so as to further restrict the free swing range of the flat wire bundle 1 in the opening 32.

[0049] Further, the material of the bushing 3 is polyoxymethylene resin. The polyoxymethylene resin has superior wear resistance and self-lubricating property, and has good oil resistance and peroxide resistance.

[0050] Please refer to Figure 7The utility model discloses a kind of car windows, including multi-conductor integrated wiring harness, still including car window body 8, in car window body 8 including bracket 81, guide wheel 82, wire storage cavity 83 and coil spring 84, bracket 81 slidingly installed on car window body 8, guide wheel 82 is fixedly installed on car window body 8, flat wiring harness 1 is connected with bracket 81, flat wiring harness 1 is abutted with guide wheel 82, wire storage cavity 83 receives flat wiring harness 1 and coil spring 84.Specifically, first plug interface 6 is electrically connected with car window glass end power receiving interface, second plug interface 7 is electrically connected with car window power supply interface, flat wiring harness 1 is arranged between car window glass end power receiving interface and car window power supply interface.Bush 3 is fixedly installed on bracket 81, car window glass and bracket 81 synchronous lifting.Car window body 8 is further provided with wire storage cavity 83 receiving flat wiring harness 1, and wire storage cavity 83 is provided with coil spring 84.By prior art, flat wiring harness 1 is arranged in coil spring 84, and coil spring 84 can be wound and released flat wiring harness 1 when bracket 81 lifts car door glass, and coil spring 84 can be wound and collected flat wiring harness 1 when bracket 81 lowers car door glass.Flat wiring harness 1 is in the process of rising or falling, under the action of bush 3, fixed rotary joint 4, coil spring 84 and guide wheel 82, the wide surface of flat wiring harness 1 is oriented in front-back direction (in vehicle body coordinates), flat wiring harness 1 is always abutted with guide wheel 82 and tangent to it, the included angle between flat wiring harness 1 and bracket 81 will change constantly, flat wiring harness 1 is abutted with guide wheel 82 in plane, instead of the point contact of round bundle wire and guide wheel in prior art, which increases the contact area, not only flat wiring harness 1 is more stable in expansion and contraction, but also bracket 81 is stable in lifting and lowering, and flat wiring harness 1 adopts three small bundles, the bending radius difference of outer side wires is small, the outer side wires are not easy to break, and the service life of flat wiring harness 1 is prolonged.It should be noted that, because the space at car door glass power receiving interface is relatively large, the distance between bracket 81 and car door glass power receiving interface is short, and the bending degree of first wire segment 2 is small, so the first wire segment 2 still uses round bundle wire, and the second wire segment 5 also uses round bundle wire.
