[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following description, with reference to the accompanying drawings, describes a method for manufacturing vehicle high-voltage wires, an apparatus for manufacturing vehicle high-voltage wires, and a vehicle according to embodiments of the present invention.

[0030] Figure 1 This is a schematic diagram of the manufacturing process of a vehicle high-voltage wire in one embodiment of the present invention.

[0031] like Figure 1 As shown, the method for manufacturing vehicle high-voltage wires includes:

[0032] S101, obtain the location information and operating parameters of each high-voltage device in the vehicle.

[0033] Specifically, in this embodiment, the arrangement position and operating parameters of each high-voltage device are different in vehicles of different models. After the overall vehicle arrangement is carried out, the position information of each high-voltage device in the vehicle is directly obtained, and the operating parameter information of each high-voltage device is obtained according to the information on the nameplate of each high-voltage device.

[0034] S102, determine the routing information of the high-voltage line based on the location information of the high-voltage device.

[0035] Specifically, once the location information of the high-voltage devices is determined, the orientation of the high-voltage line interfaces is also determined because the location of the high-voltage devices is fixed. At this point, the routing information of the high-voltage lines can be determined, including the connection relationships between the high-voltage lines of each high-voltage device and the routing information of the high-voltage lines.

[0036] S103, determine the high-voltage line type information based on the routing information and operating parameters.

[0037] Specifically, different high-voltage devices have different operating parameters, meaning their rated voltage, rated current, and other information also differ. Therefore, the selection of high-voltage lines will vary between devices. In such cases, it is necessary to determine the high-voltage line's alignment information based on the routing information and operating parameters. In some examples, the high-voltage line's alignment information may include its cross-sectional area, bending location, and bending radius.

[0038] S104, manufacture high-voltage lines according to the high-voltage line profile information.

[0039] Specifically, in this embodiment, a corresponding high-voltage line is manufactured according to the high-voltage line's line type information. The length, width, and / or shape of the high-voltage line corresponding to different high-voltage line line type information can be different.

[0040] Furthermore, in some embodiments of the present invention, such as Figure 2 As shown, the high-voltage line type information is determined based on the routing information and operating parameters, including:

[0041] S201, determine the bending position and bending radius of the high-voltage line based on the wiring information.

[0042] Specifically, in this embodiment, after the vehicle layout is completed, the positions of each high-voltage device are determined. At this time, due to the location of each high-voltage device and the vehicle space or fixed reasons, when connecting the high-voltage devices with high-voltage wires, the high-voltage wires may be bent. Thus, the specific location and bending radius of the bend can be determined.

[0043] S202, determine the cross-sectional area of ​​the high-voltage line based on the operating parameters.

[0044] Specifically, the operating current and voltage of each high-voltage device in a vehicle are not the same, or the rated voltage and rated current of each high-voltage device are different. Therefore, in order to improve the transmission efficiency and safety of current and voltage, the cross-sectional area of ​​the high-voltage line can be set, that is, the thickness of the high-voltage line can be set according to the operating parameters of the high-voltage device. For example, the cross-sectional area of ​​the high-voltage line connected to the high-voltage device with a larger rated voltage is larger, while the cross-sectional area of ​​the high-voltage line connected to the high-voltage device with a smaller rated voltage is smaller.

[0045] Furthermore, in some embodiments of the present invention, such as Figure 3 As shown, a high-voltage line includes multiple sub-wires. The high-voltage line is manufactured according to its wiring specifications, including:

[0046] S301, determine the number of sub-wires based on the cross-sectional area of ​​the high-voltage line.

[0047] Specifically, in this embodiment, since the high-voltage line includes many sub-wires, the number of sub-wires can be determined based on the cross-sectional area of ​​each sub-wire after obtaining the cross-sectional area of ​​the high-voltage line.

[0048] It should be noted that, as Figure 4 As shown, the inner conductor of a high-voltage line consists of many sub-conductors. The inner conductor is wrapped with an insulation layer, which is then wrapped with a shielding layer, and the shielding layer is wrapped with a sheath layer. Therefore, the cross-sectional area of ​​the inner conductor, which consists of multiple sub-conductors, is smaller than that of the high-voltage line.

[0049] S302, determine the sub-line lengths at the inner, middle, and outer positions of the high-voltage line in the bend position based on the bending radius.

[0050] Specifically, in this embodiment of the invention, since the inner and outer lengths of the high-voltage line at the bend position will be different, the required sub-wire lengths within the high-voltage line will also be different. Therefore, after determining the bend position and bend radius of the high-voltage line based on the routing information, the sub-wire lengths at the inner, middle, and outer positions of the high-voltage line at the bend position can be further determined based on the bend radius. It should be noted that in this embodiment, the sub-wires in the high-voltage line are divided into three regions: the inner, middle, and outer positions at the bend position. If the number of sub-wires is small or the accuracy requirement for the sub-wire bend radius is high, the length of each sub-wire can be set individually to ensure that each sub-wire at the bend can be arranged well.

[0051] S303, high-voltage wires are manufactured according to the number of sub-wires, the length of the sub-wires at the inner position, the length of the sub-wires at the middle position, and the length of the sub-wires at the outer position.

[0052] Specifically, after determining the number of sub-wires, the cross-sectional area of ​​the high-voltage wire to be manufactured can be determined. Furthermore, after determining the lengths of the sub-wires at the inner, middle, and outer positions within the bend, the corresponding bending radius at each bend can be determined, allowing for the manufacture of the high-voltage wire. It is understandable that by coordinating the number of sub-wires and the corresponding sub-wire lengths at each bend position, the appropriate high-voltage wire can be manufactured directly without damaging it due to excessive bending stress.

[0053] In some examples of the present invention, after the high-voltage wire is manufactured according to the number of sub-wires, the length of the sub-wires at the inner position, the length of the sub-wires at the middle position, and the length of the sub-wires at the outer position, it can be fixed at both ends of the bend to weld and shape the high-voltage wire.

[0054] Furthermore, in some embodiments of the present invention, the length of the sub-line at the inner position is less than the length of the sub-line at the middle position, and the length of the sub-line at the middle position is less than the length of the sub-line at the outer position.

[0055] Specifically, in this embodiment, when the high-voltage line bends, the length of the inner part of the bend is less than the length of the middle part, and the length of the middle part is less than the length of the outer part. Therefore, the required lengths of the sub-wires at the inner, middle, and outer positions within the high-voltage line will differ; that is, the length of the sub-wire at the inner position will be less than the length of the sub-wire at the middle position, and the length of the sub-wire at the middle position will be less than the length of the sub-wire at the outer position. For example... Figure 5 As shown, when a high-voltage line bends, the inner part of the bend is compressed, while the outer part is stretched. Therefore, in terms of the bend position, the sub-line on the inner side is longer than the sub-line on the outer side, and the length of the sub-line gradually extends from the inner side to the outer side.

[0056] Furthermore, in some embodiments of the present invention, the high-voltage wire is manufactured according to the wire profile information, including: casting a custom high-voltage wire according to the cross-sectional area, bending position and bending radius.

[0057] Specifically, in this embodiment, the inner conductor of the high-voltage line can be a single copper wire, rather than composed of multiple thin wires. Once the cross-sectional area, bending radius, and bending position of the high-voltage line are determined, the high-voltage line can be customized using a casting method based on these parameters. If the high-voltage line has multiple bending points, its shape can be directly customized through casting, eliminating the need for excessive tensile and compressive stress and thus significantly improving its service life.

[0058] It should be noted that, in this embodiment, after determining the cross-sectional area, bending position, and bending radius, the inner conductor within the bending position of the high-voltage line can be cast by pouring molten copper. After the inner conductor is formed, it is a whole bent copper wire, thereby realizing the customization of the high-voltage line according to actual needs, avoiding waste of the high-voltage line, and saving the overall vehicle manufacturing cost.

[0059] Furthermore, in some embodiments of the present invention, the operating parameters include the operating current of each high-voltage device.

[0060] Specifically, the operating parameters in this embodiment include the operating current of the high-voltage device, i.e., the current information of the high-voltage device during operation. Different high-voltage devices require different currents during operation. If the operating current of the high-voltage device is larger, the cross-sectional area of ​​the high-voltage line connecting the high-voltage devices will be larger; if the operating current of the high-voltage device is smaller, the cross-sectional area of ​​the high-voltage line connecting the high-voltage devices will be smaller.

[0061] In some embodiments of the present invention, each high-voltage device includes: a power supply, a drive motor, a PDU, a PDU, an OBC, a DC-DC converter, a fast charging port, an EAC, and a PTC heater.

[0062] It should be noted that, in this embodiment of the present invention, the types and quantities of high-voltage devices included in different vehicle models may vary.

[0063] The following is in conjunction with the appendix Figure 6 The specific process steps of manufacturing vehicle high-voltage wires will be described in detail with reference to specific embodiments of the present invention, such as... Figure 6As shown, perform the following steps:

[0064] S1, obtain the location information and operating parameters of each high-voltage device in the vehicle.

[0065] S2, determine the routing information of the high-voltage line based on the location information of the high-voltage device.

[0066] S3, determine the bending position and bending radius of the high-voltage line based on the wiring information.

[0067] S4. Determine the cross-sectional area of ​​the high-voltage line based on the operating parameters.

[0068] S5, determine the number of sub-wires based on the cross-sectional area of ​​the high-voltage line.

[0069] S6. Determine the sub-line lengths at the inner, middle, and outer positions of the high-voltage line in the bend position based on the bending radius.

[0070] S7. High-voltage wires are manufactured according to the number of sub-wires, the length of the sub-wires at the inner position, the length of the sub-wires at the middle position, and the length of the sub-wires at the outer position.

[0071] In summary, the method for manufacturing high-voltage wires for vehicles according to the embodiments of the present invention makes it easier to fix the high-voltage wires in vehicles and prevents bending damage to the high-voltage wires, thereby improving the space utilization of the wiring and increasing the service life of the high-voltage wires.
