Compared with the motor controller in the traditional electric drive assembly, the present device has a higher degree of integration and a faster internal communication speed inside the controller.

[0053] An electric drive assembly in this embodiment is further described below.

[0054] Figure 1 is a structural schematic diagram of an electric drive assembly provided in an embodiment of the present application; Figure 2 is a structural schematic diagram of an electric drive assembly provided in an embodiment of the present application from one perspective; Figure 3 is a structural schematic diagram of an electric drive assembly provided in an embodiment of the present application from another perspective; Figure 4 is an exploded view of an electric drive assembly provided in an embodiment of the present application; Figure 5 It is a structural schematic diagram of a motor control module in an electric drive assembly provided in an embodiment of the present application; Figure 6 It is a schematic diagram of a motor control module in an electric drive assembly provided in an embodiment of the present application.

[0055] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides an electric drive assembly 10. Figure 1 It can be seen that the electric drive assembly 10 includes a power module 100 and a motor control module 200, and the motor control module 200 includes a shell 210, a first electrical component and a second electrical component; the shell 210 and the power module 100 are connected in sequence along a first direction, and the shell 210 has a first accommodating cavity 211 and a second accommodating cavity 212 that are interconnected, and the first accommodating cavity 211 and the second accommodating cavity 212 are stacked along the first direction; the first electrical component is arranged in the first accommodating cavity 211, and the first electrical component includes a main control board 220 and a drive board 240, and the main control board 220 is provided with a vehicle control unit 221, a motor control unit 222, a high-voltage battery management unit 223 and a low-voltage battery management unit 224; the second electrical component is arranged in the second accommodating cavity 212, the second electrical component includes a charging control unit 230, and the second electrical component is connected to the first electrical component through a plug-in wiring harness.

[0056] In this way, by overlapping and arranging two accommodating cavities on the shell 210, the first electrical component is placed in the first accommodating cavity 211, and the charging control unit 230 is placed in the second accommodating cavity 212, so that it is convenient to replace and disassemble the charging control unit 230; the motor controller adopts a nine-in-one design, that is, the vehicle control unit 221, the motor control unit 222, the high-voltage battery management unit 223, the low-voltage battery management unit 224, the high-voltage distribution unit, etc. are integrated together, and the vehicle control unit 221, the motor control unit 222, the high-voltage battery management unit 223, and the low-voltage battery management unit 224 are integrated into a chip design. Compared with the motor controller in the traditional electric drive assembly, the present device has a higher degree of integration, and the motor controller has a faster internal communication speed.

[0057] In some embodiments, the shell 210 includes a first shell 213 and a second shell 214 , the first shell 213 is connected to the power module 100 , and the second shell 214 and the first shell 213 are integrally formed, the first accommodating cavity 211 is disposed in the first shell 213 , and the second accommodating cavity 212 is disposed in the second shell 214 .

[0058] Among them, Figure 5 As shown, the second shell 214 is located below the first shell 213, which effectively reduces the volume of the shell 210 and improves the integration.

[0059] Among them, a mounting hole is set at the bottom of the second shell 214, and a spring clip is set inside the mounting hole. A boss matching the groove is set on the upper surface of the charging control unit 230. The charging control unit 230 is detachably connected to the second shell 214 through the boss. The purpose of this setting is to facilitate disassembly and assembly, and to facilitate maintenance and replacement.

[0060] In some embodiments, the first accommodating cavity 211 has an opening below, and the second shell 214 is disposed in the first accommodating cavity 211 through the opening.

[0061] Among them, Figure 4 As shown, the shape of the opening is the same as that of the charging control unit 230 , and the size of the opening is slightly larger than the size of the charging control unit 230 . The purpose of this design is to have enough margin to place the charging control unit 230 into the first accommodating cavity 211 .

[0062] In some embodiments, a fast charging interface 215 and a slow charging interface 216 are provided on the housing 210 , the fast charging interface 215 is used to connect to the high-voltage battery, and the slow charging interface 216 is electrically connected to the charging control unit 230 .

[0063] Optionally, the car's charging modes are divided into fast charging and slow charging. This embodiment has both fast charging and slow charging functions. Therefore, users can adopt different charging modes to charge the power battery according to actual conditions, which can bring better convenience to car users, solve the limitations of car charging, and provide a better car experience.

[0064] Specifically, during fast charging, the DC charging interface of the charging pile is connected to the fast charging interface 215 of the vehicle, and the charging pile sends a charging wake-up signal to the high-voltage battery management unit 223. The high-voltage battery management unit 223 sends a charging current instruction to the charging pile according to the rechargeable power of the power battery. At the same time, the high-voltage battery management unit 223 attracts the system high-voltage positive relay and the high-voltage negative relay, and the power battery starts to charge.

[0065] In some embodiments, the charging control unit 230 includes an on-board charger and a DC-DC converter, and the slow charging port 216 is connected to the on-board charger, which is used to charge the power battery.

[0066] Among them, during slow charging, when the vehicle is in AC charging mode, the on-board charger detects the AC charging interface signal and wakes up the high-voltage battery management unit 223. The high-voltage battery management unit 223 wakes up the on-board charger and sends a charging instruction, while closing the main relay and the power battery starts charging.

[0067] Among them, the DC-DC converter converts the high-voltage DC power of the power battery into low-voltage DC power, one part of which is used to power the low-voltage electrical equipment of the entire vehicle, and the other part is used to charge the battery. Specifically, the on-board charger and the DC-DC converter can be separate and respectively arranged in the shell 210, or they can be integrated into the shell. In this embodiment, the on-board charger and the DC-DC converter are integrated into one, which can reduce the space occupancy rate.

[0068] In some embodiments, the first shell 213 and the second shell 214 are respectively provided with plug-in interfaces, wherein the plug-in interfaces are threaded connection interfaces or quick-connect interfaces.

[0069] Among them, Figure 2 and Figure 3 As shown, a fast charging interface 215, a slow charging interface 216, and a DC bus threaded interface 217 are provided on the shell and connected by threaded connection. A liquid cooling pipeline is provided inside the shell 210. Specifically, the liquid cooling pipeline adopts a quick connection method. The purpose of such a setting is that the environment of the liquid cooling pipeline is relatively harsh, and the quick connector has higher durability and reliability.

[0070] In some embodiments, the electric drive assembly 10 also includes a liquid cooling component, which is disposed in the housing 210 and has liquid cooling pipes and pipelines. The drive plate 240 and the liquid cooling pipes are thermally connected so that the liquid cooling pipes dissipate heat for the drive plate 240.

[0071] Among them, Figure 6 As shown, the driving board 240 and the main control board 220 are respectively provided with interaction modules, and the plug-in wiring harness connects the driving board 240 and the main control board 220 through the interaction module. Specifically, an IGBT module is provided at the bottom of the driving board 240, and the input end of the IGBT module is connected to the bus capacitor, and the output end is connected to the three-phase busbar of the driving motor 110, which is used to convert the direct current of the power battery into alternating current.

[0072] Among them, a water inlet and a water outlet are provided on the shell 210, and the coolant flows into the liquid cooling pipeline and pipe from the water inlet. A part of the liquid cooling pipeline and pipe is arranged inside the shell 210, and another part is arranged outside the shell 210. Specifically, the IGBT module is in contact with the liquid cooling pipeline, thereby taking away the heat of the drive board 240, and the drive motor 110 and the reducer 120 share a lubrication pipeline, which can reduce the flow resistance of the coolant and improve the heat dissipation efficiency.

[0073] In some embodiments, the power module 100 includes a drive motor 110, a drive motor housing, a reducer 120 and a reducer housing 121, the drive motor 110 and the reducer 120 are respectively installed on the drive motor housing and the reducer housing 121, and the output shaft of the drive motor 110 is connected to the reducer 120, and the housing 210 is arranged on the reducer housing 121.

[0074] Among them, the driving motor 110 includes a front end cover, and mounting holes are arranged along the circumference of the front end cover. Bolts pass through the mounting holes to connect the reducer 120 to it. Specifically, the motor control module 200 is connected to the three-phase busbar of the driving motor 110 through a plug-in component to convert the DC power of the power battery into AC power for use by the driving motor 110.

[0075] In some embodiments, a bracket 122 is disposed on the housing 210, and a mounting portion 123 is disposed on the reducer housing 121. The mounting portion 123 is connected to the bracket 122. Figure 4 and Figure 5 shown.

[0076] Among them, a threaded hole is provided in the mounting portion 123, and a bolt passes through the threaded hole to mount the reducer 120 and the drive motor 110 on the housing 210. The purpose of such design is to facilitate subsequent disassembly and replacement. Specifically, the drive motor 110 and the reducer 120 are also connected together by a threaded connection.

[0077] In some embodiments, a vehicle includes the above-mentioned electric drive assembly 10. The type of the vehicle can be a sedan or a commercial vehicle, which is not limited in this embodiment.

[0078] Specifically, a driving chip is provided on the driving board 240, which controls the conduction or cutoff of the IGBT module. At the same time, the driving board 240 is controlled by the main control board 220. The main control chip receives two signals from the driving motor 110 and the vehicle control unit 221, and performs calculations. The driving motor 110 sends some signals of the current value, the temperature sensor, and the rotating transformer to the main control board 220 through the connector.

[0079] It should be added that the first circuit board also includes a high-voltage distribution unit, which distributes the high-voltage electricity of the power battery to high-voltage electrical equipment such as the motor control unit 222, the drive motor 110, and the DC-DC converter, and at the same time distributes the current of the fast charging interface 215 and the slow charging interface 216 to the power battery so as to charge the power battery.

[0080] It should be added that a controller local area network interface is also provided on the main control board 220, which is used to coordinate data exchange between data networks with different structures and characteristics.
