[0046] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0047] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0048] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0049] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0050] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0051] The embodiment of the present application provides a wiring harness system for an automobile, which includes a power battery 10, a storage battery 20, a fuse box 30 and a front drive motor control device 40, and also includes a DC charging harness 1, a power supply harness 2, a high-voltage distribution charging harness 3 and a front drive power high-voltage harness. Figure 1As shown, the vehicle body is provided with a charging port 50, which includes a DC charging port and an AC charging port. The DC charging harness 1 is connected to the power battery 10 and the DC charging port, respectively. The DC charging port is used for connection to an external DC charging station. The DC charging harness 1 is used to transmit current to the power battery 10, so that the power battery 10 can provide power to the vehicle. The battery 20 is used to power low-voltage devices such as vehicle lighting, central control audio, and instruments. The fuse box 30 is a device that centralizes the vehicle's fuses. The fuses are used to protect various electrical devices in the vehicle. When the circuit current is abnormal and exceeds the fuse's melting current, the fuse automatically melts to protect the circuit. The power supply harness 2 is connected to the battery 20 and the fuse box 30, respectively. The battery 20 supplies power to the fuse box 30 through the power supply harness 2. The front-drive motor control unit 40 is located in the front cabin of the vehicle. It integrates the front-drive motor and an all-in-one controller, saving space within the vehicle. Furthermore, the all-in-one controller can integrate the front-drive motor controller and controllers for various electrical appliances within the vehicle's front cabin, effectively reducing the number of electrical components and saving wiring harness control circuits. The front-drive motor control unit 40 is connected to the power battery 10 via the front-drive power high-voltage harness 4, allowing the front-drive motor to control the start and stop of the vehicle's front wheels and the all-in-one controller to control various electrical appliances within the vehicle's front cabin. The fuse box 30 is connected to the front-drive motor control unit 40 via the high-voltage power distribution and charging harness 3 to protect the all-in-one controller.

[0052] Among them, the wires of DC charging harness 1, power supply harness 2, high-voltage distribution charging harness 3 and front drive power high-voltage harness 4 are all pure aluminum wires. 2 If copper wires are used, the total weight of the wiring harness system will be too large. Therefore, this embodiment uses pure aluminum wires to replace the pure copper wires in the prior art. Aluminum itself is a light metal with a density far less than that of copper. The weight of pure aluminum wires of the same wire diameter is also far less than that of pure copper wires, thereby reducing the total weight of the wiring harness system, and then reducing the overall weight of the car, which is beneficial to increasing the car's mileage, reducing the car's acceleration time, and improving the car's handling sensitivity. Moreover, the price of pure aluminum wires is also much lower than that of pure copper wires. Therefore, when pure aluminum wires are used for the wires of the DC charging harness 1, the wires of the power supply harness 2, the wires of the high-voltage distribution charging harness 3, and the wires of the front drive power high-voltage harness 4, the cost of the wiring harness system can also be reduced.

[0053] like Figure 1As shown, the wiring harness system also includes a charger 60 and an AC charging harness 5. The AC charging harness 5 is connected to the charger 60 and the AC charging port, respectively. The AC charging port is used to connect to an external AC charging station. The charger 60 is also electrically connected to the power battery 10 to convert AC power into DC power for powering the power battery 10. If the vehicle is charging at high power, the AC charging harness 5 can also be made of pure aluminum wire, which can also reduce the total weight and cost of the wiring harness system.

[0054] It should be noted that, considering that the electrical conductivity and tensile strength of pure aluminum wires are inferior to those of pure copper wires, if the number of wires in the wiring harness remains unchanged, the diameter of the pure aluminum wires used to replace the pure copper wires in the above-mentioned DC charging harness 1, power supply harness 2, high-voltage distribution charging harness 3, front drive power high-voltage harness 4, and AC charging harness 5 should be 1.6 times the diameter of the original pure copper wires. In addition, the total number of wires required for each of the above-mentioned DC charging harness 1, power supply harness 2, high-voltage distribution charging harness 3, front drive power high-voltage harness 4, and AC charging harness 5 can be selected based on the specific circumstances of the power supply circuit, and this embodiment does not impose any restrictions on this.

[0055] like Figure 1 As shown, the charger 60, power battery 10, and storage battery 20 can be integrated. This not only saves space inside the vehicle but also helps reduce wire paths and wiring harness length, thereby achieving a lightweight wiring harness system. The power battery 10 can also be integrated with a DC-DC converter (DC / DC). The DC-DC converter is connected to the power battery 10 and storage battery 20 respectively, converting the high-voltage DC power of the power battery 10 into a low-voltage DC power of 12V for charging the storage battery 20.

[0056] like Figure 1 As shown, the wiring harness system also includes a rear-drive motor control device 70 and a rear-drive power high-voltage wiring harness 6. The rear-drive motor control device 70 integrates the rear-drive motor and the rear-end controller. The rear-drive motor control device 70 is connected to the power battery 10 through the rear-drive power high-voltage wiring harness 6, so that the rear-drive motor can control the start and stop of the vehicle's rear wheels and the rear-end controller can control various electrical appliances in the vehicle's rear cabin. Since the rear-drive power high-voltage wiring harness 6 is located where moving parts are installed, the wires of the rear-drive power high-voltage wiring harness 6 can be made of pure copper wire with good flexibility to increase the service life of the rear-drive power high-voltage wiring harness 6. The total number of wires required for the rear-drive power high-voltage wiring harness 6 and the wire diameter of the wires can be selected according to the specific conditions of the power supply circuit, and this embodiment does not impose any restrictions on this.

[0057] like Figure 1As shown, the wiring harness system also includes a left-side vehicle body control module 80, a left front door wiring harness 9, a left rear door wiring harness 11, and a vehicle body wiring harness 13. The left front door wiring harness 9 is located in the left front door of the vehicle and is connected to the electrical appliances in the left front door. The left rear door wiring harness 11 is located in the left rear door of the vehicle and is connected to the electrical appliances in the left rear door. The left-side control module 80 is connected to the left front door wiring harness 9 and the left rear door wiring harness 11 through the vehicle body wiring harness 13 to control the electrical appliances in the left front door and the left rear door. Correspondingly, the wiring harness system also includes a right-side vehicle body control module 90, a right front door wiring harness 15, and a right rear door wiring harness 12. The right front door wiring harness 15 is located in the right front door of the vehicle and is connected to the electrical appliances in the right front door. The right rear door wiring harness 12 is located in the right rear door of the vehicle and is connected to the electrical appliances in the right rear door. The right-side control module 90 is connected to the right front door wiring harness 15 and the right rear door wiring harness 12 through the vehicle body wiring harness 13 to control the electrical appliances in the right front door and the right rear door.

[0058] Because the vehicle doors contain moving parts, the wires in the left front door harness 9, the left rear door harness 11, the right front door harness 15, and the right rear door harness 12 are all made of flexible pure copper wire to extend the harness's service life. The total number of wires and their diameters required for the left front door harness 9, the left rear door harness 11, the right front door harness 15, and the right rear door harness 12 can be selected based on the specific conditions of the power supply circuit and are not limited in this embodiment.

[0059] like Figure 1 As shown, the wiring harness system also includes a front-end electrical appliance assembly 100, a front cabin wiring harness 7, and a cockpit wiring harness 8. The left-side control module 80, the right-side control module 90, and the front-end electrical appliance assembly 100 are respectively connected to the fuse box 30 through the front cabin wiring harness 7, so that the fuse box 30 plays a role in protecting the safety of the left-side control module 80, the right-side control module 90, and the front-end electrical appliance assembly 100. The front cabin wiring harness 7 can also be used to connect the front-wheel drive motor control device 40 with the various electrical appliances in the front cabin of the car, and to connect the front-end electrical appliance assembly 100 with the right-side control module 90; the cockpit wiring harness 8 is used to connect the left-side control module 80 with the right-side control module 90. In addition, as Figure 1 As shown, the wiring harness system also includes a tail end control module 110 and a tail wiring harness 14. The tail end control module 110 is connected to the various electrical appliances at the rear of the vehicle body through the tail wiring harness 14 to control the various electrical appliances at the rear of the vehicle body. The tail end control module 110 can also be connected to the right side control module 90 of the vehicle body through the vehicle body wiring harness 13.

[0060] Among them, the front-end electrical appliance assembly 100 specifically includes an electric horn, an electronic fan, front lamps, a camera and a radar. By integrating the above electrical appliances into one, the number of electrical appliances can be effectively reduced, the occupied space can be saved, the wire path can be reduced, the length of the wiring harness can be shortened, and the wiring harness system can be lightweight.

[0061] The wires of the front cabin harness 7, the cockpit harness 8, the body harness 13 and the tail harness 14 can be aluminum alloy wires or copper alloy wires, and can be made of 0.75mm 2 Aluminum alloy wire replaces the original 0.5mm 2 Compared with pure copper wire, aluminum alloy wire has the advantages of low cost and light weight, which can reduce the total weight and cost of the wiring harness system. Moreover, the mechanical properties of aluminum alloy wire can be greatly improved compared with pure aluminum wire, avoiding the problems of low elongation, poor creep resistance and poor flexibility of pure aluminum wire, which is conducive to increasing the connection reliability of the wiring harness system. Alternatively, you can use 0.22mm 2 or 0.13mm 2 The copper alloy wire replaces the original 0.35mm 2 Pure copper wires are made of copper alloys. Compared to pure copper wires, copper alloy wires have higher strength, hardness, and conductivity. Copper alloy wires with similar performance have a smaller diameter than pure copper wires, which helps reduce the total weight and cost of the wiring harness system. Furthermore, the total number of wires and their diameters required for the front cabin harness 7, cockpit harness 8, body harness 13, and rear harness 14 can be selected based on the specific conditions of the power supply circuit, and this embodiment does not impose any restrictions on this.

[0062] In addition, in the DC charging harness 1, power supply harness 2, high-voltage distribution charging harness 3, front drive power high-voltage harness 4, AC charging harness 5, rear drive power high-voltage harness 6, front cabin harness 7, cockpit harness 8, left front door harness 9, right front door harness 15, left rear door harness 11, right rear door harness 12, body harness 13 and tail harness 14 mentioned above, the wires of each harness are welded and connected with terminals so that the harness can be connected to the connector through the terminal. Specifically, the welding method can be ultrasonic welding or friction welding. The terminal can be provided with burrs, so that when the terminal and the wire are crimped, the burr structure can penetrate into the wire to enhance the connection effect between the two, thereby increasing friction and reducing the risk of the terminal and the wire being detached. In addition, after the welding step, the connection part of the terminal and the wire can also be treated with anti-corrosion, that is, a chemical anti-corrosion agent is applied to the connection part and then covered with a thermoplastic tube to improve the service life of each harness.

[0063] In summary, the design of the wiring harness system provided in this application should follow Figure 2The method steps shown are: physical layout, electrical integration design, aluminum conductor selection, aluminum alloy conductor selection, copper alloy conductor selection and flexible printed circuit board selection in sequence, which are described in detail below:

[0064] 1. Physical layout: The characteristics of the physical layout are mainly in the physical layout of the electrical appliances and the wiring harness topology layout.

[0065] The characteristic of electrical layout is to centrally arrange electrical components of the same system to reduce the physical distance between electrical components in the same system, so as to reduce the wire path, shorten the length of the wiring harness, and realize the lightweight of the wiring harness system; the characteristic of wiring harness topology layout is to reduce wiring harness segments, connectors and terminals while combining the convenience of vehicle assembly, and follow the principle of easy production and assembly to reduce costs and improve assembly efficiency. Moreover, reducing wiring harness segments is also conducive to reducing signal transfer, thereby improving the reliability of the wiring harness system.

[0066] 2. Electrical integration: By integrating the design of various electrical functions, the number of electrical components can be effectively reduced, thereby reducing the wiring harness connection loops and reducing the weight of the wiring harness. The characteristics of electrical integration are mainly in power distribution and ground distribution.

[0067] Power distribution is characterized by matching fuses, relays, and wire diameters: power supply circuits are rationally combined and fuse capacity is set. Ground distribution is characterized by combining similar grounding types: by analyzing the interference and sensitivity characteristics of various components within the system, as well as the operating levels, signal types, and power supply voltages of each circuit within the system, the system's ground wires are classified and grouped, and a rational design is implemented, converging ground wires of the same type or group at a single point. Furthermore, grounding should adhere to the principles of proximity and placement of grounding points in easily accessible locations.

[0068] 3. Aluminum conductor selection: Since the diameter is 0.22mm 2 or 0.13mm 2 Pure aluminum wire has low elongation and poor flexibility. Its tensile strength cannot meet the standard and it is easy to bend, which will affect the efficiency of terminal insertion into the sheath and inconvenience in production and installation. Therefore, aluminum wire can only be used to replace large-sized copper wire. Considering the conductivity and tensile strength of the wire, 6mm 2 Copper wires with cross-sectional sizes of 100mm and above can be replaced with pure aluminum wires (mainly including low-voltage power lines, high-voltage lines, and grounding wires). The wire diameter of the pure aluminum wire is 1.6 times that of the copper wire to meet the same electrical conductivity.

[0069] Aluminum is a light metal with a density much lower than that of copper. The price of pure aluminum wire is also much lower than that of pure copper wire. Therefore, pure aluminum wire is used to replace 6mm 2 Copper conductors with cross-sectional dimensions of 100mm and above can reduce the cost and weight of the wiring harness system.

[0070] 4. Selection of aluminum alloy wire: Considering the conductivity and tensile strength of the wire, 0.5mm 2 The copper wire can be replaced with 0.75mm 2 Aluminum alloy wire.

[0071] Specifically, aluminum alloys are alloys of aluminum, iron, and magnesium. Compared to pure aluminum wires, aluminum alloy conductors offer significantly improved mechanical properties, eliminating the inherent issues of pure aluminum wires, such as low elongation, poor creep resistance, and poor flexibility. This helps increase the reliability of wiring harness connections. Furthermore, aluminum alloy conductors offer the same advantages as pure copper conductors, such as lower cost and lighter weight.

[0072] 5. Copper alloy wire selection: Considering the conductivity and tensile strength of the wire, 0.35mm 2 The copper wire can be replaced with 0.22mm 2 or 0.13mm 2 Copper alloy conductors.

[0073] Specifically, the copper alloy may be an alloy composed of aluminum, iron, and magnesium, which has high strength, hardness, and conductivity. Compared with copper wires, the wire diameter can be reduced, and the welding connection between the wire and the terminal is facilitated.

[0074] 6. Selection of flexible printed circuit boards: Flexible printed circuit boards can be used for small current loops to better reduce weight. The key points of flexible printed circuit board application are matching with plug-ins and the selection of application locations. Currently, they are generally used in locations without moving parts such as the roof of the car and the sub-dashboard area.

[0075] The present application also provides a car, such as Figure 1 As shown, the car includes a car body 1A and the wiring harness system described in the above embodiments, which can achieve overall lightweighting of the car. Since the wiring harness system has the above-mentioned technical effects, the car including the wiring harness system should also have corresponding technical effects, which will not be repeated here.

[0076] In addition, when using the wires in steps 3, 4, and 5 above, pay attention to selecting matching terminals. The selection of terminals should not only adapt to the circuit, but also take into account the miniaturization and lightweight of the terminals to achieve lightweight wiring harness systems.

[0077] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
