[0003] A power distribution unit (PDU) is an essential component in electric vehicles and can provide suitable power distribution solutions for different high-voltage electrical equipment. However, its metal housing results in high manufacturing costs. To meet overall layout requirements, related high-voltage components (i.e., high-voltage electrical equipment) are located in different positions on each platform. Typically, even if a PDU meets capacity requirements, the orientation of the high-voltage connectors on the PDU varies depending on the layout of the high-voltage electrical equipment. As a result, PDUs cannot be easily shared between different platforms and vehicle types, making them unplatformable. Furthermore, the need to redevelop different PDUs to meet different environments increases development costs. Summary of the Invention

It should be understood that such terms can be interchanged where appropriate. Thus, the embodiments described herein may be implemented in an order other than that shown or described herein. Furthermore, the terms "comprises," "includes," and any variations thereof are intended to cover a non-exclusive "comprises." For example, a process, apparatus, product, or device that includes a series of steps or units does not necessarily explicitly list those steps or units, and may include other steps or units that are not explicitly listed or that are inherent to the process, product, or device.

[0014] A power distribution unit (PDU) is a power distribution device commonly used in electric vehicles, providing suitable power distribution solutions for different high-voltage electrical devices. In the electric vehicle field, the PDU is also called a high-voltage distribution box. Because different high-voltage electrical devices are located at different positions on the vehicle platform, PDUs with different orientations are required to meet power distribution requirements. Therefore, conventional PDUs, which can only be installed in one direction, are difficult to adapt to different platforms, making platform-wide PDUs impossible. Furthermore, the need to redesign different PDUs to accommodate different environments increases development costs.

[0015] To solve the above problems, the embodiments of the present specification provide a power distribution unit that can be installed in multiple orientations, thereby enabling compatibility with electrical devices in different orientations, improving the adaptability of the power distribution unit, and reducing the costs of developing and designing power distribution units for different platforms.

[0016] Specifically, as shown in FIG. 1 , the power distribution unit includes a housing 10 and at least one electrical control device 50; The housing 10 includes a plurality of connection end faces 101, each of which is provided with at least one electrical device port 20; The housing 10 further includes a connector 30 and a power port 40. The electrical control devices 50 are provided inside the housing 10, and one electrical equipment port 20 is connected to each electrical control device 50. The electrical control devices 50 are connected to an external power source via the power port 40 and are communicatively connected to an external controller via the connector 30, and supply power to the electrical equipment connected to the electrical equipment port 20 based on control commands from the external controller.

[0017] Here, the housing 10 of the power distribution unit is provided with a plurality of connection end faces 101, which allows the electrical equipment to receive allocated electrical energy through the connection end faces 101, and also makes it possible to accommodate the electrical equipment in multiple directions, and it may be understood that the connection end faces 101 may be a designated portion of the surface on the housing 10 or the entire outer surface of the housing 10.

[0018] The housing 10 may be made of a metal material. This ensures the strength and hardness of the housing 10 and prevents deformation of the housing 10, improving the safety of the equipment inside the housing 10. In some other embodiments, the housing 10 may be made of an alloy material. For example, if an alloy material with high strength and light weight is used, the weight of the power distribution unit is reduced, improving the efficiency of replacement and assembly of the equipment.

[0019] The housing 10 may be designed as a single piece, which improves manufacturing efficiency and reduces manufacturing costs.

[0020] Each connecting end face 101 may be configured in different shapes according to actual circumstances, such as square, triangular, irregular, etc., but is not limited to these in the embodiments of this specification.

[0021] The housing 10 is enclosed as the outer shape of the power distribution unit. The housing 10 may be a rectangular parallelepiped to facilitate installation inside an electric vehicle. Since the connection end faces 101 can be installed on different surfaces of the rectangular parallelepiped, the electrical device ports 20 can also be installed in different directions of the rectangular parallelepiped, improving the adaptability of the power distribution unit.

[0022] In some embodiments herein, there may be four connection end faces 101, and electrical equipment ports 20 may be located in any of four different directions of the power distribution unit, thereby enabling the power distribution unit to be adaptable to different platforms.

[0023] The connector 30 may be a low-voltage connector for communicatively connecting to an external controller. The external controller is connected to an electrical control device 50 inside the power distribution unit via the connector 30, controls the operating state of the electrical control device 50, and realizes the power supply output state to the electrical device port 20 connected to the electrical control device 50. For example, the low-voltage connector may be communicatively connected to a control master unit inside an electric vehicle. In this case, the low-voltage connector can be communicatively connected to all electrical control devices 50, and different electrical control devices 50 can be connected to different electrical device ports 20, thereby controlling the power usage states of different electrical devices using different electrical control devices 50. The control master unit controls the different electrical control devices 50 to output different power supply states according to actual conditions.

[0024] In some embodiments herein, only one connector 30 may be provided in the housing 10. This single connector 30 can control the operating states of all electrical control devices 50 within the power distribution unit, allowing for accurate allocation of power sources. In some other embodiments, multiple connectors 30 may be provided, for example, one connector 30 per connection end face 101. Different connectors 30 can control different electrical control devices 50 or combinations of electrical control devices 50, allowing for individual control.

[0025] In some other embodiments, when a power distribution unit is provided with multiple connectors 30, one of the connectors 30 may be defined as a main connector and the remaining connectors as backup connectors. The main connector and the backup connectors are connected in the same manner inside the power distribution unit. When the main connector is operating normally, the backup connector is idle or inactive, allowing the main connector to control the electrical control device 50 within the power distribution unit. When the main connector fails, the backup connector may be activated. For example, one of the backup connectors may be promoted to the main connector and selected to continue to control the electrical control device 50. The provision of the backup connectors can extend the operating life of the power distribution unit and improve the reliability of real-time operation of the power distribution unit.

[0026] In actual operation, the power distribution unit is further provided with an electrical control device control line 501, and the port of the connector 30 is connected to the electrical control device 50 by the electrical control device control line 501, and a control signal is sent to the electrical control device 50 by the electrical control device control line 501.

[0027] In some embodiments of the present specification, the housing 10 may be provided with only one power port 40. This allows connection to only one external power source. This single external power source can supply power to all electrical devices connected to the power distribution unit. In some other embodiments, multiple power ports 40 may be provided. For example, one power port 40 may be provided for each connecting end face 101. Different power ports 40 may be connected to different external power sources. This allows power to be supplied to different electrical device ports 20 or combinations of electrical device ports 20, and different electrical devices or combinations of electrical devices can be equipped with different power sources, thereby enabling a balanced allocation of the internal power source of the electric vehicle.

[0028] In the examples herein, at most one electrical control device 50 is connected to each electrical equipment port 20, and if no electrical control device 50 is connected to an electrical equipment port 20, a power supply port 40 is connected to the electrical equipment port 20.

[0029] Here, it may be understood that within the power distribution unit, the electrical equipment port 20 may be directly connected to the power supply port 40. In this way, the external power source can directly supply power to the electrical equipment connected to the electrical equipment port 20, and in the process, the control lines of the electrical control device 50 are reduced.

[0030] The electric control device 50 may be fixed inside the housing 10 by bolts. The fixing positions of the different electric control devices 50 may be adjusted to correspond to the electric equipment ports 20 connected thereto. The specific fixing positions are not limited to the examples in this specification.

[0031] In the embodiment of the present specification, the electrical equipment port 20 is a high-voltage electrical equipment port, and the power supply port 40 is a high-voltage battery pack port. The high-voltage electrical equipment is high-voltage electrical equipment inside an electric vehicle, and may be, for example, an air conditioning compressor, a PTC heater, etc. The high-voltage battery pack may be used in an electric vehicle or a train.

[0032] In the embodiment of the present specification, FIG. 2 is a schematic cross-sectional view taken along line AA in FIG. 1. As shown in FIG. 2, the power port 40 includes a power copper bar 401 and a first connection base 402; The first connecting base 402 is fixed to the housing 10, The power supply copper bar 401 is for connection to an external power source, and is connected to the electrical control device 50 or the electrical equipment port 20 by the connection copper bar 60, and the power supply copper bar 401 and the connection copper bar 60 are stacked and fixed on the first connection base 402, and are spaced a predetermined distance from the housing 10.

[0033] By installing the power supply copper bar 401 and the connection copper bar 60, high voltage transmission of electrical energy for transmitting high voltage electrical energy to high voltage electrical equipment can be realized, and the reliability and stability of the power distribution unit is ensured.

[0034] The power supply copper bar 401 and the connecting copper bar 60 are installed at a predetermined distance from the housing 10, thereby realizing an insulating environment between the copper bars (i.e., the power supply copper bar 401 and the connecting copper bar 60) and the housing 10, avoiding electrical connection at high voltage and improving the safety and reliability of the power distribution unit. Here, the predetermined distance may be the minimum insulating gap between each conductive part (i.e., the copper bar and the housing 10).

[0035] In the embodiment of the present specification, the first connecting base 402 includes a first bolt 421, a first nut 422, and a first insulating base 423; The first bolt 421 is fixed to the bottom of the housing 10, and optionally, the first bolt 421 is welded to the bottom of the housing 10; The first insulating base 423 is fitted onto the first bolt 421, one end of the first insulating base 423 is abutted against the housing 10, and the other end of the first insulating base 423 is formed with a first support end surface (not shown), which is used to attach the power supply copper bar 401 and the connection copper bar 60. The first nut 422 is engaged with the first bolt 421 , thereby fixing the power supply copper bar 401 and the connection copper bar 60 to the first bolt 421 .

[0036] Here, the present text may be understood as saying that the power supply port 40 is provided on the surface of the housing 10 in the form of the first bolt 421 and the first nut 422, and at the same time, the power supply port 40 is connected to equipment inside the power distribution unit, thereby forming a high-voltage circuit environment.

[0037] The power supply copper bar 401 has a first mounting hole, and the connection copper bar 60 has a second mounting hole, and the first mounting hole corresponds to the second mounting hole; The size of the first mounting hole and the second mounting hole matches the cross section of the first bolt 421, and both the first mounting hole and the second mounting hole are smaller in size than the first support end surface.

[0038] Here, it may be understood that the connection copper bar 60 and the power supply copper bar 401 are fixed between the first nut 422 and the first support end surface, thereby improving the stability of the fixation and facilitating removal and assembly. The structures of the power supply copper bar 401 and the connection copper bar 60 may be designed according to actual circumstances. For example, the power supply copper bar 401 may be plate-shaped, and the connection copper bar 60 may be curved.

[0039] In order to further improve the insulating effect of the power port 40, the surfaces of the power copper bar 401 and the connecting copper bar 60 may be coated with a first insulating layer, and optionally, the first insulating layer may be a PVC insulating layer.

[0040] In practice, the power port 40 includes a positive power port and a negative power port, which form a closed power circuit, and the positive power port accordingly includes a positive power copper bar, a positive connection copper bar, and a positive first connection base, and the negative power port includes a negative power copper bar, a negative connection copper bar, and a negative first connection base. The specific connection relationships are the same as those described above, so they will not be described in the embodiments of this specification.

[0041] In the embodiment of the present specification, the power distribution unit further includes a fuse box 70 fixed to the housing 10 by a second connection block 701; The power input end of the fuse box 70 is connected to the power port 40 by the connecting copper bar 60, and the power output end of the fuse box 70 is connected to the electrical control device 50 or the electrical equipment port 20.

[0042] Here, the fuse box 70 is connected in series to the circuit between the power port 40 and the electrical control device 50, or the fuse box 70 may be understood to be connected in series to the circuit between the power port 40 and the electrical equipment port 20. When the current information in the series-connected circuit satisfies a predetermined condition, the fuse box 70 only needs to cut off the circuit, thereby preventing danger from occurring in the series-connected circuit and improving the reliability and safety of the power distribution unit.

[0043] The fuse box 70 may be connected to the electric control device 50 by a copper bar to provide a high-voltage transmission path. Correspondingly, the fuse box 70 may also be connected to the power port 40 by a copper bar.

[0044] In the embodiment of the present specification, FIG. 3 is a schematic cross-sectional view taken along the line BB in FIG. 1 . As shown in FIG. 3 , the second connecting base 701 includes a second bolt 711, a second nut 712, and a second insulating base 713; The second bolt 711 is fixed to the bottom of the housing 10, and optionally, the second bolt 711 is welded to the bottom of the housing 10; The second insulating base 713 is fitted onto the second bolt 711, and one end of the second insulating base 713 is abutted against the housing 10. The other end of the second insulating base 713 is formed with a second supporting end surface, which is used to attach the fuse copper bar 714 and the connection copper bar 60. The second nut 712 is engaged with the second bolt 711 , thereby fixing the fuse copper bar 714 and the connecting copper bar 60 to the second bolt 711 .

[0045] Here, it may be understood that the provision of the second connection stands 701 on both ends of the fuse box 70 allows the fuse box 70 to be stably fixed inside the housing 10, and the provision of the second insulating stands 713 allows the fuse copper bar 714 and the connecting copper bar 60 to be positioned at a predetermined distance from the housing 10. Optionally, by making the heights of the second insulating stands 713 and the first insulating stands 423 the same, the fuse copper bar 714 and the connecting copper bar 60 can be positioned at a predetermined distance from the housing 10, ensuring a certain level of insulation.

[0046] The fuse copper bar 714 and the connecting copper bar 60 are fixed between the second nut 712 and the second support end surface, which improves the stability of the fixation and makes them easy to remove and assemble. The structures of the fuse copper bar 714 and the connecting copper bar 60 can be designed according to actual circumstances. For example, the fuse copper bar 714 can be plate-shaped, and the connecting copper bar 60 can be curved.

[0047] Furthermore, in the embodiment, a third mounting hole is opened in the fuse copper bar 714, and a fourth mounting hole is opened in the connecting copper bar 60, and the third mounting hole corresponds to the fourth mounting hole; The size of the third and fourth mounting holes matches the cross section of the second bolt 711, and the size of both the third and fourth mounting holes is smaller than the size of the second support end face.

[0048] In order to further improve the insulating effect of the power port 40, the surface of the fuse copper bar is coated with a second insulating layer, which is a PVC insulating layer.

[0049] In an embodiment of the present specification, Fig. 4 is a schematic diagram of one connection end surface 101 of the power distribution unit in the present specification. As shown in Fig. 4, a plurality of uniformly arranged electrical device ports 20, two connectors 30, and one power port 40 are provided, and a cover plate 102 is provided at the open end of the housing 10, and the size of the cover plate 102 matches the size of the open end of the housing 10. Optionally, the cover plate 102 may be fixed to the open end of the housing 10 in an engaged manner. This makes it easy to attach and detach the cover plate 102, and also improves the efficiency of maintenance and adjustment of the devices inside the power distribution unit.

[0050] The multi-orientation mountable power distribution unit provided herein has an electrical device port 20 on each connection end face 101. However, in actual use, not all electrical device ports 20 are necessarily in use, and some electrical device ports 20 may be empty. Therefore, to improve the sealing effect of the internal environment of the power distribution unit, the power distribution unit optionally further includes a seal corresponding to each electrical device port 20. When an electrical device port 20 is empty, the seal is inserted into the electrical device port 20 to maintain the electrical device port 20 in a sealed state. The installation of the seal maintains the empty electrical device port 20 in a sealed state, preventing external impurities (e.g., dust, water vapor, etc.) from entering the interior of the power distribution unit and extending the operating life of the power distribution unit.

[0051] The seal may be a sealing plug that matches the shape of the electrical equipment port 20. In this case, the sealing plug can be stably inserted into the electrical equipment port 20, thereby reducing the probability of it falling off.

[0052] In the embodiment of the present specification, the power distribution unit further includes a sensor provided in the connection line of each electrical equipment port 20 for obtaining information on the current or voltage output from the electrical equipment port 20. Optionally, the sensor includes a current sensor and / or a voltage sensor.

[0053] Here, it may be understood that when the power distribution unit does not have a fuse box 70 inside or when some of the power supply lines do not have fuse boxes 70, a sensor may be used to obtain current or voltage information on the power supply lines to ensure that the power supply lines are in a normal operating state in order to improve the operational stability of the power distribution unit. Furthermore, when the power supply lines are not in a normal operating state, an external controller may be used to control the power supply to the electrical control device 50 to be cut off or to stop the output of electrical energy from the external power source, thereby ensuring the operational safety of the power distribution unit.

[0054] In the embodiment of the present specification, the electrical control device 50 includes a relay and / or a microcontroller unit (MCU). Each electrical control device 50 is connected to one electrical equipment port 20. The electrical control device 50 is connected to an external power source via a power supply port 40 and is communicatively connected to an external controller by a connector 30, and supplies power to the electrical equipment connected to the electrical equipment port 20 based on a control command from the external controller.

[0055] In the embodiment of the present specification, the power distribution unit further includes fixing holes 103 provided on the edge of the housing 10 for fixing the power distribution unit to the interior of the electric vehicle. Optionally, the fixing holes 103 may be located at four positions and provided on each of the four directions of the housing 10. In this way, the power distribution unit can be further fixed to the interior of the electric vehicle by bolts, ensuring the stability of the power distribution unit inside the electric vehicle.

[0056] The present disclosure provides a power distribution unit that can be mounted in multiple orientations, the power distribution unit including a housing 10 and at least one electrical control device 50, the housing 10 including a plurality of connecting end surfaces 101 each having at least one electrical device port 20, the housing 10 further including a connector 30 and a power port 40, the electrical control devices 50 being mounted inside the housing 10, each connected to one electrical device port 20, the electrical control devices 50 connected to an external power source via the power port 40 and communicatively connected to an external controller by the connector 30, and supplying power to the electrical devices connected to the electrical device port 20 based on a control command from the external controller. By providing a power distribution unit that can be mounted in multiple orientations, the present disclosure enhances the platform-specific characteristics of the power distribution unit, improves the adaptability of the power distribution unit to different platforms, and saves design and manufacturing costs.

[0057] Based on the power distribution unit that can be attached in a plurality of orientations provided above, an embodiment of the present specification further provides a system, which is a power distribution system, the system including: a power terminal, a control terminal, an electric device, and the power distribution unit that can be attached in a plurality of orientations; the power supply terminal is connected to the power distribution unit to supply power to the electrical devices connected to the power distribution unit; The control end is connected to the power distribution unit, for distributing electrical energy to the electrical devices connected to the power distribution unit.
