[0020] Furthermore, the step of connecting the vehicle's electrical components to the connection area further includes:

[0021] Determine the relative positions of the vehicle's electrical components and the connection area;

[0022] The torsion angle is determined based on the relative position.

[0023] Based on the stated torsion angle, the vehicle's electrical components are connected to the connection area.

[0024] Furthermore, the multiple flattened area interfaces correspond to different automotive functions.

[0025] Furthermore, the flat cable board interface uses copper or aluminum conductors.

Detailed Implementation

[0052] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0053] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0054] Reference Figure 2 This embodiment illustrates a flowchart of the steps in an embodiment of a connection method for an automotive electrical system according to the present invention; the connection method for the automotive electrical system specifically includes the following steps:

[0055] Step 201: Obtain the vehicle's electrical interface information;

[0056] In this embodiment of the invention, the electrical interface information of the vehicle can be collected to obtain the vehicle's electrical interface information.

[0057] Step 202: When the automotive electrical interface information is not a flat cable board interface, change the automotive electrical interface corresponding to the automotive electrical interface information to the flat cable board interface;

[0058] After obtaining the automotive electrical interface information, it is possible to identify electrical interfaces on the vehicle that are not flat cable board interfaces. For electrical interfaces that do not meet the requirements, they can be redeveloped, and the automotive electrical interfaces corresponding to the automotive electrical interface information can be changed to flat cable board interfaces, so that all interfaces of the vehicle can use flat cable board interfaces.

[0059] Step 203: Perform regional power distribution on the flat cable board interface, dividing it into multiple flattened regional interfaces;

[0060] Regional power distribution is implemented for the flat cable board interfaces of the entire vehicle, dividing the flat cable board interfaces into multiple flattened interface areas. The number of flattened interface areas is not limited in this embodiment of the invention. However, in a preferred example, there are 12 flattened interface areas.

[0061] Step 204: Determine the connection area based on the flattened area interface;

[0062] Based on the flat area interface, the positions of the vehicle's electrical components are projected onto the horizontal plane of the vehicle body to form an effective area for arrangement, namely the connection area.

[0063] Step 205: Connect the vehicle's electrical components to the connection area to achieve vehicle electrical flattening.

[0064] Then the car's electrical components are connected to the corresponding connection area, achieving automotive electrical flattening.

[0065] This invention involves acquiring the vehicle's electrical interface information; when the vehicle electrical interface information is not a flat cable board interface, changing the corresponding vehicle electrical interface to the flat cable board interface; performing regional power distribution on the flat cable board interface, dividing it into multiple flattened area interfaces; determining connection areas based on the flattened area interfaces; and connecting the vehicle's electrical components to the connection areas to achieve vehicle electrical flattening. By using flat cable boards to replace traditional wires, the weight of the conductors can be significantly reduced, to less than 1 / 5 of the original conductor cross-section. This not only reduces the weight and cost of the wiring harness but also lowers the overall vehicle cost and fuel consumption.

[0066] Reference Figure 3 The diagram illustrates a flowchart of another embodiment of the connection method for an automotive electrical system according to the present invention; the connection method for the automotive electrical system specifically includes the following steps:

[0067] Step 301: Obtain the vehicle's electrical interface information;

[0068] In this embodiment of the invention, the three-dimensional structure of the vehicle wiring harness for electrical connection can be referred to... Figure 4 The projection of the vehicle wiring harness three-dimensional structure can be referenced. Figure 5 First, we can obtain the vehicle's electrical interface information to identify which automotive electrical interfaces cannot use FCB (Flat Cable Board) / FFC (Flexible Printed Circuit) / FPC (Flexible Flat Cable) interfaces.

[0069] Step 302: When the automotive electrical interface information is not a flat cable board interface, change the automotive electrical interface corresponding to the automotive electrical interface information to the flat cable board interface;

[0070] When the automotive electrical interface information is not a flat cable board interface, the corresponding automotive electrical interface can be changed to a flat cable board interface so that the whole vehicle can use FCB and facilitate the implementation of flattening.

[0071] Step 303: Distribute power to the flat cable board interface in a regional manner, dividing it into multiple flat area interfaces; the flat area interfaces are located in the vehicle's usable area; the multiple flat area interfaces correspond to different vehicle functions; the flat cable board interface uses copper or aluminum conductors;

[0072] In this embodiment of the invention, the overall vehicle principle can be drawn based on all electrical components in the vehicle. Based on this principle, regional power distribution can be performed on all flat cable board interfaces, dividing them into multiple flattened interface areas. For example... Figure 6 As shown, the interface is divided into 12 flattened areas. The FCB (Flat Cable Packet) layout avoids mounting points for other vehicle components, as well as perforated or right-angled folded areas, allowing the FCB to be centrally located within usable vehicle space. Multiple flattened area interfaces correspond to different vehicle functions; one flattened area interface corresponds to one function. Regarding the conductor selection for the flat cable pack interfaces, copper and aluminum conductors can be used. Using aluminum conductors can save costs if the FCB interface width W meets the total current requirement. However, if the width W is insufficient, copper-aluminum alloy conductors can be used. Alternatively, when a minimum width W is required, copper conductors or conductors with higher conductivity can be used.

[0073] Step 304: Calculate the equivalent line cross-section of the flattened area interface based on the equivalent cross-sectional area of ​​the vehicle's electrical components;

[0074] Based on the electrical circuits of the vehicle and the required overcurrent cross-sectional area for each circuit, the conductors are flattened. The flattening process must meet requirements for battery interference and temperature rise. For each interface area, the equivalent area is calculated. For example, interface J1 corresponds to the left front headlight S1, brake controller S2, ACC cruise controller S3, low beam headlight S4, turn signal S5, front wiper S6…Sn. The equivalent cross-section of interface J1 is Sd = S1 + S2 + … + Sn, corresponding to the interface coefficient Fj and temperature coefficient Ft. The minimum cross-section of the interface is not less than Sj ≥ Sd / (Fj * Ft). Similarly, the circuit calculates the power supply to each component in each area for the applied electrical components, from interfaces 1 to 12. The rated current of each interface is calculated, and the required equivalent cross-sectional area, thickness h, and width W for each interface are calculated. W = Sj / h (10mm ≥ h ≥ 2mm) is then calculated, yielding the FCB. Figure 7 The interface is shown. The width can be adjusted according to the thickness and material. For areas with narrow projection zones, increasing the thickness can meet distribution requirements. Figure 8 As shown.

[0075] Step 305: Determine whether the equivalent line cross-section of the usable area of ​​the vehicle is greater than the equivalent line cross-section that satisfies the flattened area interface;

[0076] Furthermore, the equivalent line cross-section of the vehicle's usable area can be calculated, and it can be determined whether the equivalent line cross-section of the vehicle's usable area is greater than the equivalent line cross-section of the flattened area interface.

[0077] Step 306: When the equivalent line cross-section of the usable area of ​​the vehicle is not greater than the equivalent line cross-section of the flattened area interface, the flattened area interface is flattened multiple times.

[0078] For areas where the channel area is insufficient, multiple flattening methods or increasing the conductor thickness can be used. The optimal placement of components is close to the FCB (Fuel Block) to shorten the path. The equivalent conductor cross-sectional area Sd is calculated based on the power of each electrical component. The effective channel cross-sectional area St is then determined. The channel cross-section is limited by thickness, requiring a thickness of ≤10mm (similar to the Sj interface area). Under the condition that Sd is ≤0.6St, sufficient space is provided for the heat dissipation vents 33, with each vent spaced at least 10mm apart, to effectively cool the FCB. The FCB's conformal design matches the shape of the vehicle body. Interface positions are selected from 1 to 12. The interface for the mating components is as follows: Interface J1 is placed on the right front wall panel; Interface J2 on the left front wall panel; Interface J3 at the front of the center tunnel; Interface J4 on the right A-pillar; Interface J5 at the rear of the center tunnel; Interface J6 on the left A-pillar; Interface J7 at the front of the rear floor; Interface J8 on the right B-pillar; Interface J9 at the rear of the rear floor; Interface J10 on the left B-pillar; Interface J11 on the right C-pillar; and Interface J12 on the left C-pillar. The optimization is carried out by calculating the shortest loop based on the optimized path layout, and the relative positions of 12 interfaces are locally adjusted.

[0079] Furthermore, when the equivalent line cross-section of the vehicle utilization area is larger than the equivalent line cross-section of the flattened area interface, it can be directly arranged in the vehicle utilization area.

[0080] Step 307: Determine the connection area based on the flattened area interface;

[0081] Based on the distribution of flat area interfaces, the flat area interfaces for connecting the vehicle's electrical systems are determined, forming corresponding connection areas.

[0082] Step 308: Connect the vehicle's electrical components to the connection area to achieve vehicle electrical flattening.

[0083] After determining the connection area, the electrical components of the vehicle are connected to the connection area based on their corresponding connection methods, thereby achieving vehicle electrical flattening.

[0084] In an optional embodiment of the present invention, the step of connecting the electrical components of the vehicle to the connection area includes: determining the connector type of the vehicle's electrical components; when the connector type is a flat cable direct connection, connecting the vehicle's electrical components to the connection area; when the connector type is a flexible circuit adapter, determining the connector structure based on the vehicle's electrical components, and connecting the vehicle's electrical components to the connection area based on the connector structure.

[0085] In this embodiment of the invention, the connection method between the FCB and the electrical appliance can be divided into two types, as shown in the following figures. Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 There are two connection methods. The first is to directly connect the FCB (Front-Board Connector) to the appliance via a branch. This method saves on soldering but has higher manufacturing costs. The second method uses an FFC (Front-Board Connector) and FPC (Front-Board Connector). One end is soldered to the FCB, while the other end can be soldered or crimped. This method is more flexible. FCB lead crimping uses G-type or W-type crimping. The board-end terminals are electrically connected via FCB terminal 25. Depending on process requirements and automation levels, ultrasonic welding can also be used at the welding point 26. The choice of which method is more suitable for mass production while also considering cost is crucial. FCB connector 30 generally connects the appliance and the cable tray via a wire-to-board connection. Regarding connector selection, due to the FCB's shape and structure, single-pass wide-body connectors are preferred. For locations requiring width, multi-layer wide-body connectors are used. The connector length should not exceed half the interface length of the component. The connector should not have more than three layers. If more than three layers are required, an additional connector should be added. Sufficient space should be left at the connector's tail for the cable tray's bending radius. The bending radius of the cable tray should be no less than 10 times the cable tray thickness. Terminal structure 24, by attaching to the FCB connector, achieves the terminal anti-retraction function. This connector connects the FCB / FFC / FPC on one side and the electrical terminal on the other, using a multi-contact crimping method 26 to increase contact reliability. The connector adopts a segmented structure, with one part crimping the FCB and the other part inserting into the sheath cavity 29, allowing the wire harness to pass through the cavity with a fixed direction, ensuring the wire harness exit angle. Of course, both integral and hybrid connectors can be used, with the goal of connecting the wire harness to the electrical components. Segmented connectors are used for maintenance and reassembly. For connectors with a quality control capability (PPK) greater than 1.67, an integral connector can be used; to combine the advantages of both, a hybrid connector is generally used, thus achieving the overall connection between the FCB and the electrical components. Different connector types are then connected to the connection area.

[0086] In this embodiment of the invention, the step of connecting the vehicle's electrical components to the connection area further includes: determining the relative position of the vehicle's electrical components and the connection area; determining a torsion angle based on the relative position; and connecting the vehicle's electrical components to the connection area based on the torsion angle.

[0087] Since FCB, FFC, and FPC are all flat and lack the ability to twist wires, preventing twisting is paramount during assembly. The torsional angle between the electrical components and the FCB interface must be calculated in advance, and this angle must be strictly controlled during manufacturing. The FCB must also be firmly attached to the vehicle body to prevent damage from stress. Adhesive bonding is used to secure the FCB to the vehicle body, and positioning points are added to each FCB, with no fewer than four positioning points. The tilt angle of the FPC or FFC leading from the base plate should not exceed 80 degrees, and the length of the lead wire should be greater than 1.05 times and less than 1.3 times the distance between the FCB and the electrical component. The assembly sequence is as follows: first, assemble the main FCB, then the sub-FCBs, and finally the short-circuit connectors between FCBs. The wires connecting the FCB and the electrical component are then assembled. The FCB must be protected during assembly and disassembly using a plastic protective film. Based on the torsional angle, the vehicle's electrical components are connected to the connection area.

[0088] Furthermore, the repair of each flattened area interface can be performed by cutting and welding, or by replacing the entire component. The area is cut into sections, and the connections between sections use a special overlapping welding method, with an overlap of at least 5mm. During disassembly and assembly, a flat surface of at least 50 square centimeters is used for support to prevent deformation or displacement of the metal busbars inside the FCB.

[0089] The embodiments of the present invention achieve automotive electrical flattening, which can replace traditional wires with more practical wire cross-sections, and can significantly reduce the weight of the conductor to less than 1 / 5 of the original wire cross-section. This not only reduces the weight and cost of the wiring harness, but also reduces the overall vehicle cost and fuel consumption.
