[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] according to Figure 1-4As shown, this embodiment of the invention provides a lightweight wiring harness for automobiles, including: a power cord 4 and an integrated module 1. One end of the integrated module 1 is provided with the power cord 4, and the other end of the integrated module 1 is provided with a connector 3. The connector 3 is used to connect to the signal acquisition terminal of the automobile, and the power cord 4 is used to connect to the central control unit of the automobile.

[0022] This invention provides a lightweight wiring harness for automobiles to address the problems of existing automotive wiring harnesses having many branches, being heavy, and inconvenient to manufacture. Furthermore, by providing a lightweight wiring harness, this invention achieves the goal of reducing the weight of automotive wiring harnesses, thereby reducing the number of branches, which in turn reduces the amount of material used in the wiring harness, and further reduces the cumbersome production and quality inspection problems caused by many branches.

[0023] Specifically, the integrated module 1 includes an integrated circuit board, one end of which is connected to a power line 4, and the other end of which is connected to the connector 3 via an FPC cable 2.

[0024] The integrated circuit board is a signal acquisition board, which is used to acquire information from the vehicle's signal acquisition terminal through the FPC cable 2.

[0025] In this embodiment, the integrated circuit board is used to store the automotive signals transmitted by the connector 3 and the FPC cable 2, or to transmit them to the vehicle's central control unit via the power line 4. The integrated circuit board can also be equipped with a wireless transmission module, enabling data transmission during signal transmission. When the wireless transmission module experiences information delay within a preset range, information transmission is switched to the power line 4. Furthermore, if the power line 4 fails, the fault information is reported to the central control unit, which then initiates wireless transmission for data transmission. This ensures that data transmission is not interrupted during use, thereby guaranteeing information integrity and reducing the likelihood of vehicle malfunctions due to data interruptions.

[0026] Furthermore, it also includes a grounding module, which is disposed on the integrated circuit board. The grounding module is used to ground the signal acquisition board, thereby ensuring the circuit safety of the signal acquisition board, reducing the equipment failure rate, and improving the stability and reliability of automotive electrical signal transmission.

[0027] Furthermore, connector 3 is used to connect to the signal output terminal of the vehicle. Also, connector 3 is used to connect to a vehicle signal output terminal with an input current less than 1A.

[0028] The integrated module 1 is provided with a connector 5, which is used to detachably connect the integrated module 1 to the power cord 4. The other end of the power cord 4 is provided with a terminal block 6.

[0029] In this embodiment, all automotive signal lines connected to the connector 3 can be connected via the FPC cable 2, achieving more stable electrical signal transmission and improving data stability. Simultaneously, data transmission via the FPC cable 2 and the integrated circuit board avoids the problem of numerous branches in existing wiring harnesses. That is, by utilizing the circuit board and the FPC cable 2, the original branched wiring harnesses are integrated into an electronic module, significantly reducing the size and weight of the automotive wiring harness. Furthermore, the wiring harness structure in this invention can be divided into two parts during actual production: the first part is the fabrication of the integrated circuit board, and the second part is the electrical connection of the PFC cable and power line 4 to the integrated circuit board, achieving rapid soldering and assembly.

[0030] Traditional automotive wiring harnesses involve assembling individual cables, winding them together, and then crimping each cable to a terminal block 6 according to the signal line or harness definition. Finally, connectors are installed on the terminal blocks 6. This assembly relies entirely on manual labor and has not formed a systematic production method that allows machines to replace manual labor, resulting in extremely low production efficiency. Furthermore, existing automotive wiring harnesses require manual inspection after preparation. If a cable is found to be non-conductive, has a loose connection, or exhibits abnormal signal, the outer protective layer and winding layer of both the branch cable and the main cable must be completely stripped before the problem can be identified. This process is both costly and difficult.

[0031] The wire harness provided in this invention can be quickly inspected by setting detection points on the integrated circuit board when performing signal or finished product quality testing. Once a fault occurs, the fault information indicated by the detection points can be used to troubleshoot and obtain the fault information of the corresponding device. Then, the corresponding device can be replaced or repaired. For example, if the integrated circuit board is faulty, the integrated circuit board can be repaired or replaced. If the FPC cable 2 is faulty, the PFC cable can be directly replaced, which greatly saves production efficiency and improves production quality. It also reduces the possibility of poor contact at the wire harness connector terminals caused by the large number of traditional sub-wire harnesses.

[0032] At the same time, it reduces the amount of wires used in traditional wire harnesses, the amount of connectors, and the amount of plugs, effectively reducing production costs and overall wire harness weight, and achieving lightweight design by utilizing integrated FPC cabling 2.

[0033] Furthermore, the assembly of the integrated circuit board, FPC cable 2, and power cable 4 in this invention is simple and easy to operate. Compared to traditional multi-branch automotive wiring harnesses, the assembly workload of this invention is 3-5 pieces per minute, while a skilled worker can only complete 2-3 pieces of the same specification automotive wiring harness in eight hours. The automotive wiring harness of this invention can efficiently and with high quality complete the production of automotive wiring harnesses, greatly increasing the production and supply of automotive wiring harnesses.

[0034] In this invention, connectors 5 and terminals 6 are respectively provided at both ends of the power cord 4, which facilitates the detachable connection of the power cord 4 to the integrated module 1 and the detachable connection of the power cord 4 to the central control unit.

[0035] Figure 3 In the existing automotive wiring harness, A1 is a traditional connector, A2 is a sheathing layer, A3 is a signal line, and A4 is a plug. It can be clearly seen that there are many sub-wiring harnesses, and the traditional connector A1 on the main wiring harness is also relatively large.

[0036] Compared to the present invention Figure 3 After automotive wiring harnesses are manufactured, they obtain... Figure 4 As can be seen from the product, its wiring harness is significantly reduced, and the integration through integrated modules greatly improves the communication stability between the wiring harnesses. Furthermore, traditional automotive wiring harnesses, due to their numerous sub-wiring harnesses and signal lines (A3), require cutting according to the signal lines (A3), matching each harness definition, and then assembling. During the assembly process, continuous quality inspection of these multi-sub-wiring harnesses is necessary to prevent any incorrect installation of a signal line from causing the entire wiring harness to malfunction or damaging the central control unit.

[0037] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
