Each functional module needs to be connected to the main positive and negative wires through the branch positive and negative wires to obtain working power. When the functional modules need to communicate with each other, they also need to be connected with signal lines. Since signal lines are generally relatively short, when two functional modules are far apart, multiple signal lines and multiple connectors are needed to form a long signal line, which increases the complexity of the wiring harness structure and the manufacturing cost.

Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0036] This invention provides a wiring harness structure, which is mainly used to connect various functional modules in a car, and can also be used to connect various functional modules in buildings, ships or trains.

[0037] Please see Figures 2 to 7 One embodiment of the wiring harness structure includes a main wiring harness 100, branch wiring harnesses 200, and a signal converter 300. The branch wiring harness 200 includes power supply branches 210 and signal branches 220. The main wiring harness 100 is connected to a power supply 400. Multiple power supply branches 210 are provided and are spaced apart along the extension trajectory of the main wiring harness 100. One end of each power supply branch 210 is electrically connected to the main wiring harness 100, and the other end is used to supply power to each functional module 20 to ensure that each functional module 20 can work. Each functional module 20 can be connected to the main wiring harness 100 nearby. The distance between the power supply branches 210 on the main wiring harness 100 mainly depends on the location of each functional module.

[0038] In this embodiment, one end of the signal branch line 220 is connected to the signal converter 300, and the other end is used to connect to the functional module 20. There are multiple signal converters 300, which are respectively sleeved on the main wire harness 100. There are multiple signal branch lines 220, which are configured one-to-one with each signal converter 300 and each functional module 20.

[0039] In the prior art, when two functional modules 20 that are far apart need to communicate, multiple signal lines need to be connected into a long signal line through multiple plug-ins to meet the communication between the two functional modules 20, which increases the complexity of the wiring harness structure and the manufacturing cost.

[0040] In this invention, each signal converter 300 is mounted on the main wiring harness 100. One end of each signal branch line 220 is connected to each signal converter 300, and the other end is connected to each functional module 20. When two functional modules 20 need to communicate, one functional module 20 first transmits the signal to one signal converter 300 through one signal branch line 220. Then, one signal converter 300 transmits the signal to the other signal converter 300 through the main wiring harness 100. Finally, the other signal converter 300 transmits the signal to the other functional module 20 through another signal branch line 220. By setting up the signal converters 300, the number of signal lines on the main wiring harness 100 is reduced, thereby reducing the use of some signal lines and some plug-ins, reducing the complexity of the wiring harness structure, and also reducing the manufacturing cost of the wiring harness structure.

[0041] In one embodiment, please refer to Figures 1 to 5 Each signal converter 300 includes a winding 310 and a magnetic ring 320. The winding 310 is wound around the magnetic ring 320 and forms a first wire end 311 and a second wire end 312. The signal branch line 220 includes a first signal wire 221 connected to the first wire end 311 and a second signal wire 222 connected to the second wire end 312. The main wire bundle 100 passes through the middle of each magnetic ring 320.

[0042] In a car, the functional module 20 can be a headlight module 21, a main control module 22, a driver's side module 24, a passenger side module 25, a rear door module 26, or a rear light module 27, etc.

[0043] For example, when the driver module 24 (controller) needs to communicate with the rear door module 26 (controlled), the driver module 24 applies a voltage signal to the winding 310 through its first signal wire 221 and its second signal wire 222. At this time, current flows through the winding 310. According to the principle that there is a magnetic field around a current-carrying conductor, the magnetic flux on the magnetic ring 320 will change. According to Faraday's law of electromagnetic induction, as long as the magnetic flux through a closed circuit changes, an induced current will be generated in the closed circuit. Therefore, an induced current will be generated on the main wiring harness 100, and the induced current will be transmitted through the main wiring harness 100 to... According to Lenz's law, when current flows through a conductor, a magnetic field is formed outside the conductor. Therefore, the magnetic ring 320 will be subjected to the magnetic field given by the main wire harness 100. When the magnetic field changes, the winding 310 wound on the magnetic ring 320 will generate an induced current. The induced current multiplied by the resistance of the winding 310 will obtain a voltage signal. This voltage signal will be transmitted to the rear door module 26 through the first signal wire 221 and the second signal wire 222 of the rear door module 26, thereby realizing the communication connection between the driver module 24 and the rear door module 26.

[0044] Therefore, it can be concluded that by setting up a signal branch line 220 between the main driver module 24 and the signal converter 300 corresponding to the main driver module 24, and a signal branch line 220 between the rear door module 26 and the signal converter 300 corresponding to the rear door module 26, the communication connection between the main driver module 24 and the rear door module 26 can be realized, reducing the number of signal lines on the main wiring harness 100 and simplifying the wiring harness structure.

[0045] The greater the distance between two functional modules 20 that need to communicate, the more signal lines are saved by using the wiring harness structure of this invention compared to the traditional wiring method. Signal conversion is achieved by connecting the signal converter 300 to the main wiring harness 100. All signals are transmitted between the signal converters 300 through the main wiring harness 100.

[0046] It should be noted that after a functional module 20 sends a signal to the main wiring harness 100 via a signal converter 300, the signal is transmitted through the main wiring harness 100, and all signal converters 300 corresponding to the other functional modules 20 can sense the signal. The signal contains address information, and each address corresponds to a specific functional module 20. When a designated functional module 20 senses that the address information in the signal matches its own address, that functional module 20 will start receiving the signal; otherwise, that functional module 20 will not receive the signal.

[0047] By setting address information in the signal, it is ensured that one functional module 20 can control the corresponding functional module 20, thus avoiding causing the operation of all functional modules 20.

[0048] In one embodiment, please refer to Figures 2 to 5 ,as well as Figure 7 The main wiring harness 100 includes a first main wire 110 and a second main wire 120 connected to the first main wire 110. One end of the first main wire 110 is connected to the power supply 400, and the other end is connected to the power supply 400 through the second main wire 120, so that the main wiring harness 100 forms a closed loop.

[0049] The main wiring harness 100 is a closed loop, which helps to improve the performance of EMC (Electromagnetic Magnetic Compatibility) and EMI (Electromagnetic Interference). EMC refers to the fact that the machine is not affected by the surrounding electromagnetic environment when performing its intended function. EMI refers to electronic noise that interferes with cable signals and reduces signal integrity.

[0050] By integrating the first main wire 110 and the second main wire 120, a high utilization rate is achieved, the distance between the drive circuit and the controlled device is shortened, the interference that may be caused by long-distance transmission of large current is reduced, and the electromagnetic interference between the main wire harness 100 and external electronic components is prevented. This ensures that the signal converter 300 is not subject to electromagnetic interference from external electronic components during operation.

[0051] Furthermore, the signal branch 220 uses a shielded twisted pair cable to maximize the signal's anti-interference capability.

[0052] Furthermore, each signal converter 300 also includes a housing 330, with the winding 310 and magnetic ring 320 disposed inside the housing 330. The housing 330 is provided with a first through hole 331, and the first main wire 110 passes through the first through hole 331 of each signal converter 300 and the middle of each magnetic ring 320, so that the first main wire 110 can sense the change in magnetic flux on the magnetic ring 320, thereby generating an induced current on the first main wire 110.

[0053] Furthermore, the housing 330 is also provided with a second through hole 332. The second main wire 120 passes through the second through hole 332 of each signal converter 300, which can ensure that the second main wire 120 is closer to the first main wire 110. This can reduce the interference of electromagnetic signals generated by the signal converter 300 and the main wiring harness 100 during operation on external electronic products, as well as the interference of electromagnetic signals generated by external electronic products on the signal converter 300, ensuring that the main wiring harness 100 and external electronic products can work without affecting each other.

[0054] In another embodiment, the second main wire 120 is bent to bring it close to the outside of the housing 330 so that the second main wire 120 is close to the first main wire 110. However, the second main wire 120 may return to its original shape after bending, that is, it is difficult to ensure that the second main wire 120 is stably and continuously close to the first main wire 110.

[0055] In one embodiment, please refer to Figures 3 to 6 The first main wire 110 includes a first wire 111 and a second wire 112. The second main wire 120 includes a third wire 121 connected to the first wire 111 and a fourth wire 122 connected to the second wire 112. The first wire 111 and the third wire 121 are both positive wires, and the second wire 112 and the fourth wire 122 are both negative wires. In the automotive field, the negative wire can also be called the ground wire.

[0056] One end of the first wire 111 is connected to the positive terminal of the power supply 400, and the other end is connected to the positive terminal of the power supply 400 through the third wire 121, so that the first wire 111 and the third wire 121 form a closed loop. The main wire design of the closed loop helps to improve the effect of EMC and EMI, and ensures that the main wire harness 100 and the electronic products outside the loop can not affect each other during operation.

[0057] One end of the second wire 112 is connected to the negative terminal of the power supply 400, and the other end is connected to the negative terminal of the power supply 400 through the fourth wire 122, so that the second wire 112 and the fourth wire 122 form a closed loop. The main line design of the closed loop helps to improve the effect of EMC and EMI, and ensures that the signal converter 300 and the electronic products outside the loop can not interfere with each other during operation.

[0058] In this embodiment, the power supply 400 is a 12V battery. Of course, in other embodiments, the power supply 400 can also be a 24V battery, a 220V AC power supply, or a 380V AC power supply. The specific selection of the power supply 400 needs to be determined according to the operating conditions of the wire harness structure, and no specific restrictions are made here.

[0059] In this embodiment, the power supply branch line 210 includes a first power supply wire 211 and a second power supply wire 212. The first power supply wire 211 is connected to the first power wire 111, and the second power supply wire 212 is connected to the second power wire 112.

[0060] Of course, in other embodiments, the first power supply line 211 is connected to the third power supply line 121, and the second power supply line 212 is connected to the fourth power supply line 122; or, for some functional modules 20, the first power supply line 211 is connected to the first power supply line 111, and the second power supply line 212 is connected to the second power supply line 112, while for other functional modules 20, the first power supply line 211 is connected to the third power supply line 121, and the second power supply line 212 is connected to the fourth power supply line 122. Each power supply branch line 210 is connected to the power supply 400 through the main wiring harness 100 to ensure that each functional module 20 can receive power from the power supply 400.

[0061] In one embodiment, please refer to Figures 3 to 5 The signal branch line 220 is provided with a connector 223 at its end, and a connector 333 is formed on the housing 330. The connector 223 and the connector 333 are detachably connected so that the first wire end 311 can be electrically connected to the first signal wire 221, and the second wire end 312 can be electrically connected to the second signal wire 222, so as to ensure that the signal branch line 220 can send voltage signals to the winding 310 and receive voltage signals emitted from the winding 310.

[0062] Furthermore, a pin terminal can be provided on the first wire end 311, a socket terminal can be provided on the first signal wire 221, a pin terminal can be provided on the second wire end 312, and a socket terminal can be provided on the second signal wire 222. The electrical connection between the pin terminal and the socket terminal facilitates the electrical connection between the first wire end 311 and the first signal wire 221, as well as the electrical connection between the second wire end 312 and the second signal wire 222.

[0063] In one embodiment, the connector 333 is provided with an external thread, and the connector 223 is provided with an internal thread. The connector 223 and the connector 333 are detachably connected by the threaded connection of the internal and external threads.

[0064] In another embodiment, the connector 333 and the connector 223 are connected by a snap-fit.

[0065] In one embodiment, the housing 330 is connected to the external component by an adhesive layer. By fixing the position of the housing 330, the signal converter 300 can be prevented from moving on the main wiring harness 100 during the operation of automobiles, trains, and ships, which could cause the signal branch line 220 to be pulled apart.

[0066] In another embodiment, please refer to Figure 7The housing 330 has mounting holes 334, and the wiring harness structure also includes fasteners that pass through the mounting holes 334 and connect to external components. When the signal converter 300 is damaged, this method makes it easier to disassemble and replace the signal converter 300 compared to adhesive bonding.

[0067] Please see Figures 1 to 7 One embodiment of the automobile includes a frame 10, functional modules 20 and a wiring harness structure of any of the above embodiments. Multiple functional modules 20 are provided and are all mounted on the frame 10. The functional modules 20 are connected to each other through the wiring harness structure.

[0068] Understandably, when the two functional modules 20 need to communicate, one functional module 20 first transmits the signal to a signal converter 300 through a signal branch 220. Then, the signal converter 300 transmits the signal to the other signal converter 300 through the main wiring harness 100. Finally, the other signal converter 300 transmits the signal to the other functional module 20 through another signal branch 220. By setting up the signal converter 300, the number of signal lines on the main wiring harness 100 is reduced, and the manufacturing cost of the wiring harness structure is reduced. By replacing or simplifying the complex wiring harness structure of traditional automobiles, the manufacturing cost of automobiles is reduced.

[0069] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
