[0002] With the deepening of my country's dual-carbon strategy, the market share of new energy vehicles has greatly increased. In related technologies, the on-board charger (OBC) module, DC / DC (Direct Current / Direct Current) module, and power distribution unit (PDU) module in the integrated control structure of new energy vehicle power supplies are mostly single or dual-unit components, distributed relatively dispersedly, resulting in wasted internal space. Furthermore, the DC / DC module is a crucial component in the electric vehicle's three-electric system (battery, motor, and electronic control system), outputting power through a high-current copper busbar connected to a connector after rectification. In related technologies, installing the high-current copper busbar usually requires tooling, leading to cumbersome installation procedures, excessive conduction impedance, and reduced contact reliability.

The magnetic core is disposed on the copper busbar body and is used to suppress surges in the circuit. The connecting portion is connected to the copper busbar body and is used to position and connect the copper busbar assembly to a target component within the on-board power integrated control structure. The electrical connection portion, the connecting portion, and the positioning hole are located on opposite sides of the copper busbar body, and the electrical connection portion is used to electrically connect to electrical components in the on-board power integrated control structure.

This eliminates the need for tooling and assembly stress during installation. The connecting portion 140 positions and connects the copper busbar assembly 100 to the target component within the vehicle power integrated control structure 200, preventing rotation and deformation of the copper busbar assembly 100 during installation, reducing conduction impedance, improving contact reliability, lowering installation costs, and increasing installation efficiency. Furthermore, by incorporating a magnetic core 130 in the copper busbar assembly 100, surges in the circuit are suppressed, enhancing the filtering capability of the copper busbar assembly 100 and protecting the charging circuit and battery.

[0042] like Figure 1 As shown, the copper busbar assembly 100 includes: a copper busbar body 110, a positioning hole 120, a magnetic core 130, a connecting portion 140, and an electrical connection portion 150. The positioning hole 120 protrudes from the copper busbar body 110 and provides positioning guidance when the copper busbar assembly 100 is mounted on the vehicle power integrated control structure 200. The magnetic core 130 is disposed on the copper busbar body 110 and is used to suppress surges in the circuit. The connecting portion 140 is connected to the copper busbar body 110 and is used to position and connect the copper busbar assembly 100 to the electromagnetic interference filter board 250 within the vehicle power integrated control structure 200. The electrical connection portion 150, the connecting portion 140, and the positioning hole 120 are located on opposite sides of the copper busbar body 110, and the electrical connection portion 150 is used for electrical connection to the circuit board 260 in the vehicle power integrated control structure 200.

[0043] like Figures 2 to 3 As shown, the housing 210 includes an upper chamber 214 and a lower chamber 215 that are interconnected. The lower chamber 215, on the outer side of the housing 210, also includes a first plug-in 211, which is a direct current (DC) power output plug-in capable of supplying power to the vehicle's low-voltage battery. The housing 210 also includes a positioning post 212.

[0044] like Figures 2 to 3 As shown, the OBC module 220 and DC / DC module 230 are disposed in the lower chamber 215, the PDU module 240 is disposed in the upper chamber 214, and the circuit board 261 is disposed inside the housing 210. The OBC module 220, DC / DC module 230, and PDU module 240 are electrically connected to the circuit board 261. The first plug-in 211 is electrically connected to the DC / DC module 230. The copper busbar assembly 100 is disposed between the DC / DC module 230 and the first plug-in 211, as shown. Figure 5 as well as Figure 6 As shown, the positioning hole 120 is connected to the positioning post 212 to install the copper busbar assembly 100 inside the housing 210.

[0045] like Figure 3 and Figure 4 As shown, the electromagnetic interference filter board 250 is disposed inside the housing 210. The electromagnetic interference filter board 250 includes a third mounting hole 251, which connects to the connecting part 140 to connect the electromagnetic interference filter board 250 to the copper busbar assembly 100. The connecting part 140 includes a connecting post 141 and a connecting hole 142, with the connecting hole 142 extending through the connecting post 141. The connecting post 141 protrudes from the copper busbar body 110. The third mounting hole 251 connects to the connecting post 141 to install the electromagnetic interference filter board 250 onto the copper busbar assembly 100, facilitating the connection between the copper busbar assembly 100 and the electromagnetic interference filter board 250. The connecting hole 142 may have threads inside, allowing a screw matching the threads to be connected within the connecting hole 142, preventing the electromagnetic interference filter board 250 from falling off the copper busbar assembly 100 and ensuring the stability of the electrical or mechanical connection.

[0046] like Figures 2 to 3 As shown, the technical solution of this application integrates the OBC module 220, DC / DC module 230 in the lower chamber 215, and PDU module 240 in the upper chamber 214, into a single housing 210. This concentrated distribution improves component reuse, enhances space utilization within the vehicle power supply integrated control structure 200, and reduces costs. In this embodiment, the PDU module 240 and OBC module 220 transmit control signals via a low-voltage wiring harness and power signals via a high-voltage wiring harness.

[0047] like Figures 3 to 4As shown, the housing 210 includes a positioning post 212, and the vehicle power integrated control structure 200 also includes a circuit board 261. The copper busbar assembly 100 includes a positioning hole 120 and an electrical connection part 150. When installing the copper busbar assembly 100, the positioning hole 120 is connected to the positioning post 212, and the electrical connection part 150 is connected to the circuit board 261 to install the copper busbar assembly 100 inside the housing 210. The matching connection between the positioning hole 120 and the positioning post 212 can provide positioning and guiding functions for the copper busbar assembly 100 during installation. Therefore, during the installation of the copper busbar assembly 100, it is not necessary to first connect the copper busbar assembly 100 to the circuit board 261 using tooling, avoiding the problem of rotation and deformation of the copper busbar assembly 100 during installation, and avoiding installation stress between the contact surfaces of the copper busbar assembly 100 and the circuit board 261 and the first plug-in 211, which could lead to excessive impedance and reduce the risk of vibration. It also eliminates the need to first fix the copper busbar assembly 100 inside the first plug-in 211 and housing 210 using tooling before connecting it to the circuit board 261. This helps reduce conduction impedance, improve contact reliability, reduce installation costs, and increase the installation efficiency of the copper busbar assembly 100. The diameter of the positioning hole 120 is typically slightly larger than the diameter of the positioning post 212 inside the housing 210 to allow the positioning post 212 to be inserted while maintaining a certain tolerance. During installation, the positioning post 212 is inserted into the positioning hole 120, which provides precise positioning and installation guidance, allowing the position of the copper busbar assembly 100 within the housing 210 to be stable and precisely controlled. Furthermore, this connection also helps reduce vibration and improve overall strength.

[0048] like Figure 3 As shown, the vehicle power integrated control structure 200 also includes: a power module 260, which is disposed in the lower chamber 215. The power module 260 includes a circuit board 261, an OBC module 220 and a DC / DC module 230 disposed on the circuit board 261, and an electrical connection part 150 electrically connected to the DC / DC high current output port on the circuit board 261.

The third mounting hole 251 of the electromagnetic interference filter board 250 is connected to the connecting part 140 of the copper busbar assembly 100. The connecting part 140 includes a connecting post 141 and a connecting hole 142. The third mounting hole 251 is connected to the connecting post 141 to install the electromagnetic interference filter board 250 on the copper busbar assembly 100. The connecting hole 142 may have threads inside, and a screw matching the threads can be connected into the connecting hole 142 to prevent the electromagnetic interference filter board 250 from falling off the copper busbar assembly 100 and ensure the stability of the electrical or mechanical connection. By connecting the electromagnetic interference filter board 250 to the copper busbar assembly 100 and the housing 210, the output power supply is grounded to the housing 210, which helps to enhance the electromagnetic interference resistance of the electromagnetic interference filter board 250. In the embodiments of this application, the connector is a screw.

[0050] like Figure 5 As shown, the housing 210 also includes a sixth mounting hole 218. The first mounting hole 160 and the sixth mounting hole 218 are connected by a connector to install the copper busbar assembly 100 inside the housing 210. In this embodiment, the connector is a screw.

[0051] In this embodiment, a fuse and a relay are also provided inside the upper chamber 214. The relay serves to switch on / off and detect connections, while the fuse provides overcurrent protection.

[0052] In this embodiment, the outer side of the housing 210 also includes one or more of the following components electrically connected to the PDU module 240: a battery (BAT) plug-in C1, a motor control unit (MCU) plug-in C2, a heater / air conditioning power (Positive Temperature Coefficient / Air Conditioning Power, PTC / ACP) plug-in C3, an upper and lower assembly plug-in C4, an alternating current-in (AC-in) plug-in C5, an alternating current-out (AC-out) plug-in C6, and a signal plug-in C7, which can supply power to the vehicle battery pack and electrical equipment. By setting one or more of the following on the outside of the housing 210: BAT plug-in C1, MCU plug-in C2, PTC / ACP plug-in C3, top and bottom mounting plug-in C4, AC-in plug-in C5, AC-out plug-in C6, and signal plug-in C7, it is not only beneficial to realize the vehicle power integrated control structure 200 to charge the electric vehicle battery pack and low-voltage battery, but also to realize the separate power supply for vehicle air conditioner, PTC, MCU, 220V AC equipment, etc., which can improve the configuration flexibility of PDU module 240 and facilitate cost-free selection.

[0053] In this embodiment, the power module includes one or more of the following: a unidirectional OBC module 220, a bidirectional OBC module 220, a single DC / DC module 230, and a combination of unidirectional OBC and DC / DC modules. By platformizing the power module 260 design, the power module can be adapted to the configuration requirements of different models, which is beneficial for achieving low-cost selection and reducing the development cycle.

[0054] like Figure 2 , Figure 8 , Figure 9 The figures shown are different embodiments of this application.

[0055] like Figure 2 As shown, one embodiment of this application includes all of the following: BAT plug-in C1, MCU plug-in C2, PTC / ACP plug-in C3, upper and lower assembly plug-in C4, AC-in plug-in C5, AC-out plug-in C6, and signal plug-in C7. That is, it includes slow charging function, in-vehicle inverter function, out-of-vehicle inverter function, air conditioning cooling function, PTC heating function, upper and lower assembly power supply function, etc., and also includes PDU module 240, bidirectional OBC module 220 and DC / DC module 230.

[0056] like Figure 8As shown, another embodiment of this application includes a BAT plug-in C1, an MCU plug-in C2, a PTC / ACP plug-in C3, an upper and lower assembly plug-in C4, an AC-in plug-in C5, and a signal plug-in C7, which includes slow charging function, air conditioning cooling function, PTC heating function, upper and lower assembly power supply function, etc., but does not include in-vehicle inverter function, that is, it includes a PDU module 240, a unidirectional OBC module 220, and a DC / DC module 230.

[0057] like Figure 9 As shown, another embodiment of this application includes a BAT plug-in C1, an MCU plug-in C2, an upper and lower assembly plug-in C4, and a signal plug-in C7, which includes a slow charging function but does not include an in-vehicle inverter function, an air conditioning cooling function, a PTC heating function, or an upper and lower assembly function. In other words, it includes a PDU module 240 without the upper and lower assembly, a unidirectional OBC module 220, and a DC / DC module 230.

[0058] Those skilled in the art can determine the configuration of the external plugs and power modules 260 of the vehicle power integrated control structure 200 according to actual needs. This application does not limit the configuration of the external plugs and power modules 260 of the vehicle power integrated control structure 200. The PDU module 240 and the power module 260 adopt a modular design and are flexibly configured.

[0059] In this embodiment, a three-dimensional water channel is also provided inside the lower chamber 215. The three-dimensional water channel is independently configured, and the OBC module 220 and DC / DC module 230 are fitted into the three-dimensional water channel. Cooling liquid can flow within the three-dimensional water channel to dissipate heat from the OBC module 220 and DC / DC module 230. By independently configuring the three-dimensional water channel inside the lower chamber 215, and fitting the OBC module 220 and DC / DC module 230 into the three-dimensional water channel, the cooling liquid can flow within the three-dimensional water channel to dissipate heat from the OBC module 220 and DC / DC module 230, which helps to solve the heat dissipation problem of the OBC module 220 and DC / DC module 230.

[0060] like Figures 2 to 3 As shown, the housing 210 also includes a first cover plate 216 and a second cover plate 217. The first cover plate 216 is detachably installed on the upper chamber 214 to seal the upper chamber 214, and the second cover plate 217 is detachably installed on the lower chamber 215 to seal the lower chamber 215. By providing the first cover plate 216 and the second cover plate 217 on the housing 210, the first cover plate 216 can be detachably installed on the upper chamber 214 to seal the upper chamber 214, which facilitates later product maintenance. The second cover plate 217 can be detachably installed on the lower chamber 215 to seal the lower chamber 215, which helps to maintain the internal sealing state of the housing 210.
