Description

Technical Field

[0001] This utility model belongs to the field of power distribution box technology, and in particular relates to a high-voltage power distribution box. Background Technology

[0002] With the vigorous development of new energy electric commercial vehicles, unlike the multi-functional modules of passenger cars, commercial vehicles also need to use high-voltage distribution boxes to distribute power and protect vehicle electrical equipment.

[0003] Currently available high-voltage distribution boxes on the market are often quite large due to the need to adjust them according to the space of the vehicle frame, thus wasting too much space. Furthermore, the arrangement of connectors and the overall vehicle wiring direction make it difficult to compress space, as exemplified by the highly integrated battery high-voltage box disclosed in CN202011034905.2. Therefore, the high-voltage distribution box provided by this utility model is of great significance in addressing these problems. Utility Model Content

[0004] This utility model provides a high-voltage distribution box. With sufficient internal space, the mounting feet are lengthened to ensure secure fixing to the vehicle body, and reinforcing ribs are added to increase their structural strength. Input and output connectors are arranged along the mounting feet, making efficient use of the increased space and allowing for easy cable installation and removal without interference in vehicle wiring. All connectors are arranged in a straight line, minimizing the overall height of the distribution box. External connectors connect to internal copper busbars via cables, dividing the main circuit into three paths to accommodate different electrical devices. The distribution box also includes three fuses for equipment protection. In summary, this design solves the problems described in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a high-voltage distribution box, which includes a vent valve, an input connector, a box cover, several fuses, copper busbars, a first output connector, a second output connector, a signal connector, and a box body.

[0010] Furthermore, the input connector, the first output connector, the second output connector, and the signal connector are arranged in a line, and there is a gap between each connector.

[0011] The present invention has the following advantages over the prior art:

[0012] (1) When a high voltage distribution box in this utility model is used, under the condition that there is enough space inside the distribution box, the size of the mounting feet is lengthened to meet the fixing of the distribution box and the vehicle body, and the structural strength of the mounting feet is increased by adding reinforcing ribs to the mounting feet.

[0013] (2) When using the high-voltage distribution box of this utility model, the input connector and the output connector are arranged in the direction of the mounting feet, which can make reasonable use of the space after the increase in the size of the mounting feet, so that the cables can be easily installed or removed, and there will be no interference problem in the wiring of the whole vehicle.

[0014] (3) When the high voltage distribution box of this utility model is used, all the connectors are arranged in a straight line to reduce the overall height of the distribution box as much as possible. The external connectors of the distribution box are connected to the internal copper busbar through cables. The main circuit is divided into three circuits through the copper busbar to meet the needs of different electrical equipment. The distribution box is equipped with three fuses to protect the electrical equipment.

[0026] Please see Figure 1-5 As shown, this utility model discloses a high-voltage distribution box, including a vent valve 1, an input connector 2, a cover 3, several fuses 4, a copper busbar 5, a first output connector 6, a second output connector 7, a signal connector 8, and a housing 9. The housing 9 is made of aluminum alloy ADC12. The vent valve 1 is installed on the housing 9. The input connector 2 is installed on one side of the housing 9, and external power can be input through the input connector 2. The first output connector 6, the second output connector 7, and the signal connector 8 are installed on the other side of the housing 9. The cover 3 is installed on the top of the housing 9 and is made of AL6061 aluminum plate. The fuses 4 and the copper busbar 5 are installed inside the housing 9. The fuses 4 can protect the electrical equipment from being burned by abnormal current.

[0027] The input connector 2 and the fuse 4 are both electrically connected to the copper busbar 5. There are three fuses 4, and each fuse 4 is electrically connected to the corresponding first output connector 6 and second output connector 7 via a cable. The external power supply can be distributed to different fuses 4 through the copper busbar 5. The external power supply can be output to various electrical devices through multiple fuses 4. Thus, the main circuit can be divided into three circuits through the copper busbar 5 to meet the needs of different electrical devices.

[0028] The outer wall of the enclosure 9 is equipped with mounting feet, which are asymmetrically distributed and reinforced with ribs. By lengthening the mounting feet, the electrical distribution box can be fixed to the vehicle body, and the ribs can increase the structural strength of the mounting feet.

[0029] Among them, the input connector 2, the first output connector 6, and the second output connector 7 are all arranged along the direction of the mounting feet, which can make reasonable use of the space after the increase in the size of the mounting feet, so that the cables can be easily installed or removed without any interference problems in the overall vehicle wiring.

[0030] The input connector 2, the first output connector 6, the second output connector 7, and the signal connector 8 are arranged in a line, with gaps between each connector. This minimizes the overall height of the distribution box and allows for easy hand operation by providing sufficient gaps.

[0031] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all connected to the external main controller and 220V mains power. The main controller is a conventional known device that can play a control role.

[0033] The working principle of this utility model is as follows:

[0034] In use, this utility model allows external power to be input through the input connector 2. The external power can be distributed to different fuses 4 via the copper busbar 5. Multiple fuses 4 can output the external power to various electrical devices. Thus, the main circuit can be divided into three paths via the copper busbar 5 to meet the needs of different electrical devices. The fuses 4 can protect the electrical devices from being burned out by abnormal current. The outer wall of the box 9 is provided with mounting feet. By lengthening the mounting feet, the distribution box can be fixed to the vehicle body. The input connector 2, the first output connector 6, and the second output connector 7 are all arranged along the direction of the mounting feet. The increased space after the mounting feet are increased can be used reasonably, so that the cables can be easily installed or removed without interference problems in the vehicle wiring. The input connector 2, the first output connector 6, the second output connector 7, and the signal connector 8 are arranged on a line, and there is a gap between each connector. This can reduce the overall height of the distribution box as much as possible, and the sufficient gaps can facilitate manual operation.
