[0003] In order to meet the different customized needs of customers for automobiles, the automobile charging and distribution system needs to make different functional matches, and the key to the matching function of the automobile charging and distribution system lies in the configuration of the high-voltage distribution box.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The traditional high-voltage distribution box has a single function and cannot be customized according to different customer requirements. For example, it is impossible to choose whether to include a fast charging interface, a slow charging interface, an air conditioning interface, a heater interface, a modification interface, etc. In view of this, the embodiment of the present application improves a high-voltage distribution box preparation method and related devices.

[0032] It is understandable that the high-voltage distribution box can be assembled from a high-voltage distribution box shell and a high-voltage distribution box internal structure. Among them, the high-voltage distribution box shell needs to reserve installation holes for the interface of the high-voltage distribution box internal structure. For the internal structure of the high-voltage distribution box including different interfaces, different high-voltage distribution box shells need to be selected. In order to meet the customer's customized needs for different functions of the car, an embodiment of the present application provides a high-voltage distribution box mold set, which prepares a high-voltage distribution box shell with different installation holes by selecting molds, and adapts to the internal structure of the high-voltage distribution box with different interfaces.

[0033] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a high-voltage distribution box mold assembly provided in an embodiment of the present application. Figure 1 As shown, the top view of the high-voltage distribution box 100 is taken as an example to introduce the pending molds included in the high-voltage distribution box mold set.

[0034] In an embodiment of the present application, the high-voltage distribution box mold set includes six pending molds, each of which corresponds to each side of the high-voltage distribution box shell.

[0035] In a possible implementation, the high-voltage distribution box mold set includes a first pending mold corresponding to the first side surface of the high-voltage distribution box housing. Figure 1 As shown, the first side surface corresponds to the rear side surface A of the high-voltage distribution box 100. The first type of mold to be determined includes a first mold A1, a second mold A2 and a third mold A3.

[0036] Among them, the first mold A1 includes the installation hole position 101 of the target automobile air conditioning interface (Air Conditioner, AC), the second mold A2 includes the installation hole position 102 of the target automobile heater interface (Positive Temperature Coefficient, PTC), and the third mold includes the installation hole position 101 of the target automobile air conditioning interface and the installation hole position 102 of the target automobile heater interface.

[0037] In a possible implementation, the high-voltage distribution box mold set includes a second to-be-determined mold corresponding to the second side surface of the high-voltage distribution box housing, such as Figure 1 As shown, the second side surface corresponds to the left side surface B of the high-voltage distribution box 100. The second type of mold to be determined includes a fourth mold B1, a fifth mold B2 and a sixth mold B3.

[0038] Among them, the fourth mold B1 includes the installation hole position 103 of the target vehicle fast charging interface (DC), the fifth mold B2 includes the installation hole position 104 of the target vehicle slow charging interface (OBC), and the sixth mold includes the installation hole position 103 of the target vehicle fast charging interface and the installation hole position 104 of the target vehicle slow charging interface.

[0039] In a possible implementation, the high-voltage distribution box mold set includes a third pending mold corresponding to the third side surface of the high-voltage distribution box housing, such as Figure 1 As shown, the third side surface corresponds to the top E of the high-voltage distribution box 100. The third type of mold to be determined includes a seventh mold E1 and an eighth mold E2.

[0040] The seventh mold E1 does not include the installation hole position of the target vehicle cargo box power interface, and the eighth mold includes the installation hole position 105 of the target vehicle cargo box power supply.

[0041] In a possible implementation, the high-voltage distribution box mold set includes a fourth pending mold corresponding to the fourth side surface of the high-voltage distribution box housing, such as Figure 1 As shown, the fourth side surface corresponds to the bottom F of the high-voltage distribution box 100. The fourth type of mold to be determined includes a ninth mold F1 and a tenth mold F2.

[0042] The ninth mold does not include a mounting hole for mounting the high-voltage distribution box housing, and the tenth mold includes a mounting hole 106 for mounting the high-voltage distribution box housing.

[0043] In a possible implementation, the high-voltage distribution box mold set includes a fifth to-be-determined mold corresponding to the fifth side surface of the high-voltage distribution box housing, such as Figure 1 As shown, the fifth side surface corresponds to the front side surface C of the high-voltage distribution box 100. The fifth type of mold to be determined includes the installation hole 107 of the target vehicle low-voltage communication interface.

[0044] The high-voltage distribution box mold set includes a sixth pending mold corresponding to the sixth side surface of the high-voltage distribution box housing, such as Figure 1 As shown, the sixth side surface corresponds to the rear side surface D of the high-voltage distribution box 100. The sixth pending mold includes a mounting hole 108 of a target automobile micro controller unit (MCU) interface.

[0045] In addition, the first undetermined mold may also include installation holes for the power interface, such as Figure 1 109 shown. The second undetermined mold may also include mounting holes for the battery interface, such as Figure 1 110 shown.

[0046] The above-mentioned high-voltage distribution box mold set includes six pending molds and thirty-six high-voltage distribution box set mold configurations. Therefore, during the development process, only the DV, PV and vehicle durability verification of the full set of mold configurations is required, which greatly reduces the development cost and cycle of the high-voltage distribution box. In the actual application process, according to the customer's customized requirements for automotive functions, the mold corresponding to the customized requirements can be selected from the high-voltage distribution box mold set to prepare the high-voltage distribution box.

[0047] In order to better understand the high-voltage distribution box preparation method provided in the embodiment of the present application, Figure 2 , the high-voltage distribution box preparation method provided in the embodiment of the present application is introduced.

[0048] See also Figure 2 , Figure 2 A schematic diagram of a process for preparing a high-voltage distribution box provided in an embodiment of the present application. Figure 2 As shown, the method for preparing the high-voltage distribution box comprises the following steps:

[0049] S201: Obtaining the customized needs of target customers for target cars.

[0050] During the application process, the target customer's customized needs for the target car can be obtained. The car can be an electric car, a hybrid electric car, etc. The customized needs include whether the target car has air conditioning, heating, fast charging, slow charging, installation and modification interfaces, etc.

[0051] For example, for commercial vehicles, the electricity cost and charging time are factors that must be considered. Large customer operations generally have DC charging piles that charge quickly and efficiently. Therefore, the entire vehicle must be equipped with a fast charging configuration, while the slow charging time takes 8 hours or even longer, which is slow and cannot meet the needs of fast charging. Therefore, for such customers, a fast charging interface needs to be configured on the high-voltage distribution box. However, for individual commercial vehicle users, using rest time or slow charging at night can not only save electricity costs, but also charge faster. The corresponding high-voltage distribution box for such customers needs to be equipped with a slow charging interface.

[0052] It is understandable that in the north, the winter temperature is low and lasts longer, so the heating function is used more and the air conditioning cooling is less. For this reason, the corresponding high-voltage distribution box needs to be equipped with a heater interface. In the south, the summer temperature is high and lasts longer, so the air conditioning cooling function is used more and the heating function is less. For this reason, the corresponding high-voltage distribution box needs to be equipped with an air conditioning interface.

[0053] For some special vehicle users, the vehicle high-voltage distribution box needs to reserve a cargo box power interface to charge the commercial vehicle so as to install special equipment. For example, the second-class chassis of electric commercial vehicles does not reserve a DC conversion power port, which makes it difficult to convert special vehicles to power. For this, the high-voltage distribution box needs to be equipped with a cargo box power interface.

[0054] The above is only used as an example to illustrate various customization requirements that may exist in the process of personalized design by customers. In the actual customization process, there may be various other possible customization requirements according to actual needs, which are not limited here.

[0055] S202: Selecting a target mold corresponding to the customization requirement from the pending molds included in the high-voltage distribution box mold set corresponding to the target vehicle.

[0056] After determining the customization requirements of the target customer for the target car based on the above S201, a target mold corresponding to the customization requirements can be selected from the pending molds included in the high-voltage distribution box mold set corresponding to the target car according to the customization requirements.

[0057] The target mold is used to prepare the high-voltage distribution box shell corresponding to the target automobile high-voltage distribution box. It can be understood that the high-voltage distribution box shell includes six sides ABCDEF. If each target mold corresponds to each side of the high-voltage distribution box shell, it is necessary to select the target mold corresponding to the six sides from the pending molds. The target mold includes the installation holes of the internal structure of the high-voltage distribution box corresponding to the customized requirements.

[0058] As described in the above embodiment, the first type of pending mold corresponding to the rear side A includes A1, A2, and A3, the second type of pending mold corresponding to the left side B includes B1, B2, and B3, the fifth type of pending mold corresponding to the front side C includes C1, the sixth type of pending mold corresponding to the right side D includes D1, the third type of pending mold corresponding to the top E includes E1 and E2, and the fourth type of pending mold corresponding to the bottom F includes F1 and F2, totaling 3+3+2+2+1+1=12 molds (see for details) Figure 1 shown).

[0059] In actual application, by obtaining information on whether the target customer needs to configure air conditioning and / or heater, fast charging and / or slow charging, and power supply for the cargo box on the target car, the target mold for preparing the high-voltage distribution box shell is selected from the pending molds included in the above-mentioned high-voltage distribution box mold set.

[0060] For example, if the target customer's customization requirements for the target car include air conditioning, fast charging and slow charging functions, the first mold A1 in the first type of pending molds, the sixth mold B3 in the second type of pending molds, the seventh mold E1 in the third type of pending molds, the tenth mold F2 in the fourth type of pending molds, the fifth type of pending mold C1 and the sixth type of pending mold D1 can be selected from the above-mentioned high-voltage distribution box mold set.

[0061] In actual application, the inner cavity of the high-voltage distribution box shell is designed as a standard dynamic mold. When configuring a high-voltage distribution box with different interfaces, it can be achieved by switching the slider molds on different sides without affecting the other five sides. In actual application, the target mold can be selected according to customized requirements to prepare the high-voltage distribution box, thereby reducing the design, mold opening and verification costs of the high-voltage distribution box, greatly shortening the development cycle, and also achieving platform universality.

[0062] S203: Using the target mold to prepare a high-voltage distribution box housing corresponding to the target vehicle.

[0063] After selecting six target molds based on the above S202, the six target molds can be used to prepare the high-voltage distribution box shell corresponding to the target car. In practical applications, the high-voltage electric box of the car needs to ensure the safety of electricity use under high-voltage working conditions. For this reason, the high-voltage distribution box needs to meet a certain safety protection level, such as the IP67 standard. Therefore, the high-voltage distribution box generally uses cast aluminum alloy and sheet metal shell.

[0064] The high-voltage distribution box shell is generally a hexahedral structure, which can be die-casted in one step through a mold. This can not only ensure the beautiful appearance of the high-voltage distribution box, but also quickly generate an aluminum alloy high-voltage distribution box shell, thereby improving the production efficiency of the high-voltage distribution box shell.

[0065] S204: Assembling the high-voltage distribution box shell and the internal structure of the high-voltage distribution box to obtain a high-voltage distribution box that meets the customized requirements.

[0066] In actual application, the internal structure of the high-voltage distribution box can be assembled and prepared according to customized requirements. Generally, the internal structure of the high-voltage distribution box is modular. Figure 3 The power distribution module shown includes a loop fuse, a relay, a plastic mounting base, connecting cables and bolts. Figure 3 Only the relay and fuse are shown. In the actual assembly process, the two ends of the power distribution module can be fixed to the reserved installation holes at the bottom of the shell by two M6 bolts, that is, the bottom slider of the high-voltage distribution box prepared by the tenth mold F2.

[0067] The internal structure may specifically include: connectors, fuses, relays, distribution modules, cables, terminals, fasteners, etc. In addition, the high-voltage distribution box includes a high-voltage distribution box housing and an internal structure of the high-voltage distribution box, and may also include components such as an upper cover and a sealing ring.

[0068] It is understandable that in the actual use of the high-voltage distribution box, there is a certain gap between the fuse and the high-voltage distribution box shell, and the fuse conducts heat slowly. If the high-voltage distribution box works for a long time, the fuse temperature is high, which can easily lead to fuse failure or affect the service life of the fuse. For example, electric vehicles take a long time to charge and cannot be completed quickly. In order to meet the demand for fast charging, the fast charging current is getting larger and the fast charging time is getting shorter. Since the high-voltage distribution box is generally naturally cooled, and since a variety of high-voltage heating components are configured inside the high-voltage distribution box, the greater the current, the greater the heat generated, causing the fast charging fuse, MCU fuse, etc. to pass a larger current, resulting in a higher fuse temperature.

[0069] In view of this, the embodiment of the present application provides a possible implementation method, that is, adding thermal conductive glue to the internal structure of the high-voltage distribution box to connect the fuse and the high-voltage distribution box housing. Since the thermal conductive glue conducts heat faster than air, the heat can be dissipated faster through the thermal conductive glue, reducing the fuse problem, solving the problem of fuse failure due to high fuse temperature and affecting the service life of the fuse, and improving the reliability of the fuse.

[0070] It can be seen from the above technical solution that the target customer's customization requirements for the target car are obtained; the target mold corresponding to the customization requirements is selected from the pending molds included in the high-voltage distribution box mold set corresponding to the target car; wherein the target mold is used to prepare the high-voltage distribution box shell corresponding to the high-voltage distribution box of the target car; the target mold includes installation holes for the internal structure of the high-voltage distribution box corresponding to the customization requirements; the high-voltage distribution box shell corresponding to the target car is prepared using the target mold; the high-voltage distribution box shell and the internal structure of the high-voltage distribution box are assembled to obtain a high-voltage distribution box that meets the customization requirements. Since the high-voltage distribution box mold set includes a variety of pending molds for preparing high-voltage distribution box shells, there are a variety of optional configuration options when preparing the high-voltage distribution box, and the high-voltage distribution box corresponding to each configuration option can be quickly produced with consistent performance, which not only meets the customer's personalized customization needs, but also shortens the high-voltage distribution box development cycle, reduces the high-voltage distribution box development cost, and improves the high-voltage distribution box preparation efficiency, thereby improving the vehicle preparation efficiency.

[0071] In view of the method for preparing a high-voltage distribution box provided in the above embodiment, the embodiment of the present application further provides a mold for preparing a high-voltage distribution box housing, the mold comprising any one of the first pending mold, the second pending mold, the third pending mold and the fourth pending mold provided in the above embodiment, as well as the fifth pending mold and the sixth pending mold. The following Table 1 provides several mold configuration options for preparing a high-voltage distribution box housing.
