Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle powertrain and a vehicle. Background Technology

[0002] Currently, the common driving mode adopted by range-extended electric vehicles is that when the power battery has a high charge, the power battery powers the drive motor to drive the vehicle. When the power battery has a low charge, the range extender, which consists of an engine and a generator, powers the drive motor to drive the vehicle. In related technologies, range-extended electric vehicles usually have two drive motors, one connected to the front wheel and the other connected to the rear wheel. However, in the above structure, the drive motor and other components are set up separately, which makes the vehicle powertrain too large and difficult to assemble, thus reducing the applicability of the powertrain.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0048] like Figures 1 to 24As shown, in order to achieve the above objectives, according to a first aspect of this application, a vehicle powertrain 1 is provided, comprising: an engine 10; a generator 20, drivenly connected to the engine 10, the engine 10 driving the generator 20 to generate electrical energy; a drive motor 30, including at least one front-wheel drive motor 31 and at least one rear-wheel drive motor 32, the front-wheel drive motor 30 being drivenly connected to the front wheels 40 of the vehicle, and the rear-wheel drive motor 30 being drivenly connected to the rear wheels 50 of the vehicle; a charging and distribution module 130, including a plurality of electrically connected high-voltage charging and distribution units; and a battery pack 150, electrically connected to the drive motor 30 and the charging and distribution module 130.

As the core component of power distribution, the power distribution unit 60 can efficiently distribute the electrical energy generated by the generator 20 to various external components. This design ensures the rational distribution and effective utilization of electrical energy, avoiding waste and loss of electrical energy.

[0052] Optionally, the engine 10, generator 20, and front-wheel drive motor 31 are integrated. This integration further reduces the overall size of the vehicle powertrain 1.

[0054] Optionally, the vehicle powertrain 1 also includes a first controller 70, which is communicatively connected to the generator 20. The first controller 70 is used to control the operating status of the generator 20. The first controller 70 can monitor the operating status of the generator 20 in real time and precisely control the generator 20 according to preset parameters or conditions. This precise control helps ensure that the generator 20 maintains its optimal operating state under various operating conditions, thereby improving its efficiency and reliability.

[0060] Optionally, the first controller 70, the second controller 80, the generator 20, and the front-wheel drive motor 31 are also integrated with the engine 10. This integration scheme can further reduce the overall size of the vehicle powertrain 1.

[0061] like Figure 7 As shown, the power distribution unit 60, the first controller 70, the generator 20, and the engine 10 are integrated. The engine 10 is a horizontally inline four-cylinder engine. The electronic control unit in the vehicle powertrain 1 is separately arranged to control the engine 10, realizing the conversion of the chemical energy of the fuel into mechanical energy and outputting it to the generator 20. The first controller 70 independently controls the generator 20 to convert mechanical energy into electrical energy. The power distribution unit 60 is connected to distribute electrical energy. The charging and distribution module 130 is connected to the starting iron battery 120, the battery pack 150, and the charging socket 140 respectively to realize the charging and discharging function and high-voltage electrical energy distribution. At the same time, the charging and distribution module 130 converts high voltage to low voltage to provide power to the 12V starting iron battery 120. The battery pack 150 is connected to the front and rear dual motors through the DC bus to provide the power required for the operation of the U-shaped dual motor assembly. The drive shafts of the two drive motors 30 of the U-shaped dual motor assembly are coaxially arranged.

[0062] like Figure 8 As shown, the engine 10, the first controller 70 and the generator 20 are integrated.

[0064] like Figure 10 As shown, the power distribution unit 60 and the first controller 70 are spaced apart. The first controller 70 is electrically connected to the vehicle's battery pack 150. The power distribution unit 60 is not integrated with the generator 20 assembly; instead, it is arranged separately and connects to two high-voltage loads, the heater (PTC: Positive Temperature Coefficient) and the compressor 90, for power distribution. Other components and functions are the same.

The vehicle also includes a load unit 110, which is electrically connected to the power distribution unit 60 and / or electrically connected to the vehicle's charging and distribution module 130. This configuration allows the power distribution unit 60 and the charging and distribution module 130 to reserve / add other high-voltage load interfaces to ensure the vehicle can perform more functions. Simultaneously, the generator 20 assembly can reserve / add high-voltage output lines to connect to the battery pack 150, retaining the boost DC power module (DC: Direct Current) and battery self-heating function. Other component systems and functions are the same. Figure 7 The proposed solution improves the vehicle's applicability.

[0066] like Figure 12As shown, the power distribution unit 60, the first controller 70, the generator 20, and the engine 10 are integrated. The electronic control unit in the vehicle powertrain 1 is arranged separately to control the engine 10. The engine 10 is an inline four-cylinder engine that converts the chemical energy of fuel into mechanical energy and outputs it to the generator 20. The first controller 70 independently controls the generator 20 to convert mechanical energy into electrical energy. The power distribution unit 60 is connected to distribute electrical energy. The charging and distribution module 130 is connected to the starting iron battery 120, the battery pack 150, and the charging socket 140 to realize charging and discharging functions and high-voltage electrical energy distribution. At the same time, the charging and distribution module 130 converts high voltage to low voltage to provide power to the 12V starting iron battery 120. The battery pack 150 is connected to the front and rear dual motors through a DC bus to provide the power required for the operation of the U-shaped dual motor assembly. The drive shafts of the two drive motors 30 of the U-shaped dual motor assembly are coaxially arranged.

[0067] like Figure 13 As shown, the engine 10 is an inline four-cylinder engine 10. The engine 10, the first controller 70 and the generator 20 are integrated. In order to ensure the feasibility of the power distribution unit 60 layout scheme, the power distribution unit 60 is designed independently. The above-mentioned integrated scheme can further reduce the overall volume of the vehicle powertrain 1.

[0068] like Figure 14 As shown, the engine 10 is an inline four-cylinder engine. The power distribution unit 60, the first controller 70, the generator 20, and the engine 10 are integrated together. The vehicle also includes a load unit 110, which is electrically connected to the power distribution unit 60 and / or electrically connected to the vehicle's charging and distribution module 130. This configuration allows the power distribution unit 60 and the charging and distribution module 130 to reserve / add other high-voltage load interfaces to ensure that the vehicle can achieve more functions.

[0069] like Figure 15 As shown, the engine 10 is an inline four-cylinder engine 10. The power distribution unit 60 and the first controller 70 are arranged at intervals. The first controller 70 is electrically connected to the vehicle's battery pack 150. The power distribution unit 60 is no longer integrated with the generator 20 assembly and adopts a separate arrangement. It is connected to two high-voltage loads, the heating element 100 and the compressor 90, to distribute electrical energy. The above-mentioned integrated scheme can further reduce the overall volume of the vehicle's powertrain 1.

[0070] like Figure 16As shown, the first controller 70, the second controller 80, the generator 20, and at least two drive motors 30 for driving connection with the front wheels 40 of the vehicle are integrated, and the generator 20 is arranged longitudinally to meet the layout requirements of the small hood sedan; the power distribution unit 60 is designed and arranged separately, connecting the heating element 100 and the compressor 90, two high-voltage loads, to distribute electrical energy. The above integrated scheme can further reduce the overall volume of the vehicle powertrain 1.

[0071] like Figure 17 As shown, the engine 10, generator 20, and at least two drive motors 30 for drive connection with the front wheels 40 of the vehicle are integrated. The power distribution unit 60 is designed and arranged separately, connecting the heating element 100 and the compressor 90, two high-voltage loads, to distribute electrical energy. The above-mentioned integrated solution can further reduce the overall volume of the vehicle powertrain 1.

[0072] like Figure 18 As shown, the power distribution unit 60, the first controller 70, the second controller 80, the generator 20, at least two drive motors 30 for drive connection with the front wheels 40 of the vehicle, and the engine 10 are integrated. This enables the distribution of power to the front generator, the front drive function, and the two high-voltage loads of the heating element 100 and the compressor 90. The above-mentioned integrated solution can further reduce the overall size of the vehicle powertrain 1.

[0073] like Figure 19 As shown, the first controller 70, the second controller 80, the generator 20, at least two drive motors 30 for drive connection with the front wheels 40 of the vehicle, and the engine 10 are integrated. The load unit 110 is electrically connected to the power distribution unit 60 and / or the load unit 110 is electrically connected to the vehicle's charging and distribution module 130. This configuration allows the power distribution unit 60 and the charging and distribution module 130 to reserve / add other high-voltage load interfaces to ensure that the vehicle can achieve more other functions. At the same time, the generator 20 assembly can reserve / add high-voltage output lines to connect to the battery pack 150, retaining the boost DC power module and the battery self-heating function, thus improving the vehicle's applicability.

[0074] like Figure 20 As shown, the front wheel 40 of the vehicle is connected to a drive motor 30, and the power generation system assembly consists of a horizontally opposed engine 12 and a generator 20. The front drive dual motors are changed to a single motor drive assembly (including a differential), which can be expanded to realize a range-extended hybrid three-electric drive vehicle powertrain 1, thus improving the applicability of the vehicle.

[0075] like Figure 21As shown, the rear wheel 50 of the vehicle is connected to a drive motor 30. The power generation system assembly consists of a horizontally opposed engine 12 and a generator 20. The rear drive dual motors are changed to a rear motor drive assembly (including a differential), which can be expanded to realize a range-extended hybrid three-electric drive vehicle powertrain 1, thus improving the applicability of the vehicle.

[0076] like Figure 22 As shown, the power generation system assembly consists of an inline opposed engine 10 and a generator 20. The front drive dual motors are changed to a front single motor drive assembly (including a differential), which can be expanded to realize a range-extended hybrid three-electric drive vehicle powertrain 1, thus improving the vehicle's applicability.

[0077] like Figure 23 As shown, the front wheel 40 of the vehicle is connected to a drive motor 30, and the rear wheel 50 of the vehicle is connected to a drive motor 30. The power generation system assembly consists of an inline opposed engine 10 and a generator 20. The front drive dual motors are changed to a front single motor drive assembly (including a differential), and the rear drive dual motors are changed to a rear motor drive assembly (including a differential). This can be expanded to realize a range-extended hybrid three-electric drive vehicle powertrain 1, thus improving the applicability of the vehicle.

The rear wheels 50 of the vehicle are connected to one drive motor 30. This enables the vehicle to generate electricity at the front, drive the vehicle, and distribute power to the two high-voltage loads, the heating element 100 and the compressor 90, thus improving the applicability of the vehicle.

[0079] According to a second aspect of this application, a drive system assembly is provided, including the vehicle powertrain 1 described above.

[0080] According to a third aspect of this application, a vehicle is also provided, including the drive system assembly described above.

[0081] Optionally, the vehicle includes a compressor 90 and a heater 100, which are electrically connected to a power distribution unit 60.

[0082] In the vehicle powertrain 1 of this application embodiment, the engine 10 is configured as an inline engine 11 or a horizontally opposed engine 12 through the above technical solution. Since the pistons of the inline engine 11 are arranged in a straight line, the crankshaft and flywheel can also be designed to be more compact, thus reducing the height and volume of the engine 10. At the same time, the piston stroke of the horizontally opposed engine 12 is shorter and the cylinders are arranged symmetrically, which makes the overall volume of the engine 10 relatively small, thereby reducing the overall volume of the vehicle powertrain 1. This can save space in the engine compartment, meet the layout requirements of the monocoque body, and thus improve the applicability of the vehicle powertrain 1.
