Detailed Implementation

[0052] The embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this disclosure, and should not be construed as limiting this disclosure.

[0053] In the description of this disclosure, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0054] The arrangement of multiple components in the drive assembly in related technologies is relatively dispersed, resulting in a large overall size of the drive assembly, which requires a large layout space, increases the difficulty of layout of the drive assembly, and reduces the space utilization of the vehicle.

[0055] Based on this, some embodiments of the present disclosure provide a drive assembly, a power system, and a vehicle.

[0056] The following description, with reference to the accompanying drawings, describes a drive assembly provided according to some embodiments of this disclosure.

[0057] As shown in Figures 1, 2 and 3, a drive assembly 1001 according to some embodiments of the present disclosure includes: an engine 110, a first motor 120, a motor module 200 and a controller 800.

[0058] For example, as shown in Figures 1 and 4, the engine 110 and the first motor 120 are arranged along the length of the vehicle.

[0059] It should be noted that the length direction of the vehicle mentioned here can also be understood as the direction between the front and rear of the vehicle, that is, the front-rear direction shown in Figures 1 and 4. In other words, the engine 110 and the first motor 120 are arranged along the front-rear direction of the drive assembly 1001. This can make reasonable use of the space of the drive assembly 1001 in the front-rear direction and avoid increasing the space of the drive assembly in at least one of the vertical or horizontal directions due to the setting of the engine 110 and the first motor 120. This is conducive to reducing the size of the drive assembly in at least one of the vertical or horizontal directions.

[0060] As shown in Figures 1 and 3, the first motor 120, the motor module 200, and the controller 800 are arranged along the height direction of the vehicle.

[0061] It should be noted that the vehicle height direction mentioned here can be understood as the direction between the bottom and the top of the vehicle, that is, the up and down direction shown in Figures 1 and 3.

[0062] In other words, the first motor 120, the motor module 200, and the controller 800 are arranged along the height direction of the vehicle, so that the first motor 120, the motor module 200, and the controller 800 are arranged along the vertical direction of the drive assembly, so as to make rational use of the space of the drive assembly in the vertical direction.

[0063] Compared to arranging the motor module 200 and the first motor 120 along the length of the vehicle, the above arrangement can reduce the space occupied by the drive assembly in the front-rear direction. Since the engine 110 and the first motor 120 are arranged along the front-rear direction of the drive assembly, arranging the first motor 120, the motor module 200, and the controller 800 along the vertical direction of the drive assembly allows the overall structure of the drive assembly to be arranged in both the front-rear and vertical directions. This avoids the drive assembly occupying a large amount of space in both the front-rear and vertical directions, which helps to reduce the size of the drive assembly and lower the difficulty of its layout.

[0064] It should be noted that by arranging the first motor 120, the motor module 200 and the controller 800 along the height direction of the vehicle, it is also convenient to make room below the engine 110, which is beneficial to placing the air intake of the engine 110 and the oil pan 111 below the engine 110, ensuring the smooth air intake of the engine 110.

[0065] In addition, since the first motor 120 and the motor module 200 need to be electrically connected to the controller 800, arranging the first motor 120, the motor module 200 and the controller 800 along the height direction of the vehicle can also allow the controller 800 to be placed close to the first motor 120 and the motor module 200, which makes it easier to reduce the difficulty of electrically connecting the controller 800 to the first motor 120 and the motor module 200 respectively, and helps to ensure the working performance of the first motor 120 and the motor module 200.

[0066] As can be seen from the above structure, the drive assembly 1001 in some embodiments of this disclosure arranges the engine 110 and the first motor 120 in a front-to-back manner and arranges the first motor 120, the motor module 200 and the controller 800 in a vertical manner to maximize the integration of the drive assembly and improve the integration degree of the drive assembly. This allows the drive assembly to be integrated into a whole and limited to a certain length, width and height range, reducing the volume of the drive assembly and thus reducing the difficulty of arranging the drive assembly.

[0067] Furthermore, due to the reduced size of the drive assembly, it can be arranged as a whole in the front or rear compartment of the vehicle, improving the overall space utilization of the vehicle, which is beneficial for the arrangement of related structural components of the vehicle chassis, and can make the chassis layout simple and beautiful.

[0068] It should be noted that, with the above configuration, when this drive assembly is applied to hybrid or pure electric vehicles, the small space occupied by the drive assembly allows for the provision of space for the battery pack of the hybrid or pure electric vehicle. This is beneficial for increasing the capacity of the battery pack, thereby increasing the driving range of the hybrid or pure electric vehicle. Furthermore, the increased capacity of the battery pack also allows for the interchangeability of battery packs between hybrid and pure electric vehicles, enabling the production of battery packs for hybrid and pure electric vehicles on a common platform.

[0069] Furthermore, by installing the drive assembly of some embodiments of this disclosure on the vehicle, the battery pack can be highly integrated with the chassis, thereby improving the torsional strength of the entire vehicle.

[0070] It is understood that, compared with related technologies, the drive assembly 1001 of some embodiments of this disclosure not only integrates the engine 110, the first motor 120 and the motor module 200, but also integrates the controller 800, so as to maximize the integration of the drive assembly, reduce the space occupied by the drive assembly, thereby reducing the difficulty of the drive assembly layout, and making room for the installation of the battery pack, which facilitates the increase of the battery pack capacity.

[0071] In some embodiments, as shown in Figures 1, 2, and 3, the controller 800 is disposed between the motor module 200 and the first motor 120. That is, after arranging the first motor 120, the motor module 200, and the controller 800 along the height direction of the vehicle, the controller 800 is also disposed between the motor module 200 and the first motor 120, so that the first motor 120, the controller 800, and the motor module 200 are arranged sequentially in the height direction of the vehicle.

[0072] In this way, on the one hand, the space of the drive assembly in the vertical direction can be rationally utilized, and the space of the drive assembly in the front-rear direction can be avoided due to the setting of the controller 800. This helps to reduce the space occupied by the drive assembly in the front-rear direction, reduce the difficulty of the drive assembly layout, and make room for the battery pack of hybrid and pure electric vehicles. This helps to ensure the capacity of the battery pack and improve the driving range of hybrid and pure electric vehicles.

[0073] On the other hand, it also allows the controller 800 to be positioned close to both the first motor 120 and the motor module 200, reducing the difficulty of electrical connection between the controller 800 and the first motor 120 and the motor module 200, thereby reducing the control difficulty of the first motor 120 and the motor module 200.

[0074] Meanwhile, by placing the controller 800 between the motor module 200 and the first motor 120, the motor module 200 and the first motor 120 can work together to protect the controller 800 and extend its service life.

[0075] In some embodiments, the controller 800 is electrically connected to the first motor 120 and the motor module 200, thereby facilitating the control of the first motor 120 and the motor module 200 by the controller 800 to ensure the working performance of the first motor 120 and the motor module 200, and thus ensure the working performance of the drive assembly.

[0076] In some embodiments, the controller 800 is mainly used to reasonably control the working state and power output of the first motor 120 and the motor module 200 according to the driver's requirements and vehicle conditions, so as to meet the needs of the driving conditions.

[0077] It should be noted that the simultaneous electrical connection of the controller 800 with the first motor 120 and the motor module 200 can be understood as follows: in some embodiments of this disclosure, the controllers of the first motor 120 and the motor module 200 are integrated together to form the controller 800, and the controller 800 is placed between the first motor 120 and the motor module 200, without encroaching on other space of the drive assembly, making full use of space and making the drive assembly more integrated.

[0078] In some embodiments, as shown in Figures 1, 2 and 3, a cavity is provided between the first motor 120 and the motor module 200. The cavity is used to accommodate the controller 800, which facilitates the placement of the controller 800 between the motor module 200 and the first motor 120, reducing the assembly difficulty of the controller 800.

[0079] In some embodiments, the first motor 120 and the motor module 200 are spaced apart in the height direction of the vehicle to form a cavity between the first motor 120 and the motor module 200, and the controller 800 is disposed in the cavity, thereby placing the controller 800 between the motor module 200 and the first motor 120 and reducing the assembly difficulty of the controller 800.

[0080] In some embodiments, as shown in FIG1, the motor module 200 is positioned below the first motor 120 in the height direction of the vehicle. Since the motor module 200 needs to connect to the vehicle's wheels via the drive shaft 910, positioning the motor module 200 below the first motor 120 ensures that the motor module 200 is close to the wheels, thereby ensuring that the drive shaft 910 is also close to the wheels. This allows the angle between the drive shaft 910 and the wheels to be within the allowable range, facilitating the connection between the drive shaft 910 and the wheels and ensuring the working performance of the wheels.

[0081] In some embodiments, as shown in FIG1, FIG2 and FIG3, the controller 800 has a first outer surface facing the first motor 120 and a second outer surface facing the motor module 200. The extension direction of the first outer surface is consistent with the extension direction of the outer wall surface of the first motor 120 facing the first outer surface, and the extension direction of the second outer surface is consistent with the extension direction of the outer wall surface of the motor module 200 facing the second outer surface.

[0082] In other words, the first outer surface of the controller 800 facing the first motor 120 extends along the outer wall surface of the first motor 120 facing the controller 800, and the second outer surface of the controller 800 facing the motor module 200 is arranged along the outer wall surface of the motor module 200 facing the controller 800. The two outer surfaces of the controller 800 and the first motor 120 that are arranged opposite each other have the same extension direction.

[0083] This allows the controller 800 to make rational use of the space between the first motor 120 and the motor module 200. While ensuring that the controller 800 can be effectively placed between the first motor 120 and the motor module 200, it can also avoid increasing the distance between the first motor 120 and the motor module 200 too much due to the placement of the controller 800. In other words, it avoids increasing the size of the drive assembly in the vertical direction too much due to the placement of the controller 800, which helps to reduce the volume of the drive assembly and reduce the difficulty of the drive assembly layout.

[0084] In some embodiments, the first motor 120 is a generator, and the motor module 200 includes a drive motor, thereby ensuring the working performance of the first motor 120 and the motor module 200 to a certain extent, and thus ensuring the working performance of the drive assembly.

[0085] In some embodiments, as shown in FIG1, the axis of the first motor 120 extends along the length direction of the vehicle. Since the engine 110 and the first motor 120 are arranged along the length direction of the vehicle, the above arrangement allows the output shaft of the first motor 120 to be positioned close to the engine 110, which helps to reduce the difficulty of connecting the engine 110 and the first motor 120.

[0086] Furthermore, the above-mentioned configuration can also prevent the first motor 120 from occupying too much space in at least one of the vertical or horizontal directions, which is beneficial to reducing the size of the drive assembly.

[0087] In some embodiments, the axis of the first motor 120 is parallel to the axis of the engine 110. That is, when the axis of the first motor 120 extends along the length direction of the vehicle, the axis of the engine 110 also extends along the length direction of the vehicle, further reducing the difficulty of connecting the engine 110 and the first motor 120.

[0088] In some embodiments, the engine 110 and the first motor 120 are fixedly connected, thereby ensuring the connection strength between the engine 110 and the first motor 120 and stabilizing their relative positions. This not only ensures the working performance of the engine 110 and the first motor 120, but also improves the structural stability of the drive assembly.

[0089] For example, the fixed connection between the engine 110 and the first motor 120 mentioned here can be achieved by fixing the housing of the engine 110 and the housing of the first motor 120 together with bolts, or by welding or bonding the housing of the engine 110 and the housing of the first motor 120 together.

[0090] In some embodiments, as shown in FIG1, the first motor 120 is arranged at the rear end of the engine 110 and near the middle of the engine 110 in the left-right direction. In this way, the engine 110 and the first motor 120 are arranged along the length direction of the vehicle, and the space at the rear end of the engine 110 can be rationally utilized, which facilitates the subsequent installation of other structural components at the rear end of the engine 110, thereby reducing the size of the drive assembly.

[0091] In some embodiments, the motor module 200 includes a drive motor connected to two drive shafts 910, which are spaced apart along the width direction of the vehicle and are adapted to connect to the wheel ends of the vehicle.

[0092] For example, the width direction of the vehicle mentioned here can be understood as the direction between the driver's seat and the passenger seat, which is the left and right direction shown in Figure 1. In other words, when the motor module 200 includes a drive motor, the drive motor is connected to two drive shafts 910 that are spaced apart along the left and right direction of the drive assembly. Since the drive shafts 910 are suitable for connecting to the wheel ends of the vehicle, the motor module 200 can drive the two wheel ends to move at the same time.

[0093] It should be noted that by using one drive motor to connect two transmission shafts 910 simultaneously, the structure of the motor module 200 can be simplified, thereby reducing the space occupied by the motor module 200 and helping to reduce the size of the drive assembly.

[0094] In some embodiments, the motor module 200 includes two drive motors, each of which is connected to a drive shaft 910. The two drive shafts 910 are spaced apart along the width direction of the vehicle and are adapted to connect to the wheel ends of the vehicle. That is, the motor module 200 is not limited to including one drive motor; it can also include two drive motors. When the motor module 200 includes two drive motors, each drive motor is connected to a drive shaft 910, thus allowing the motor module 200 to simultaneously drive the two wheel ends.

[0095] It should be noted that, compared to using one drive motor to connect two drive shafts 910 at the same time, each drive motor is connected to one drive shaft 910, which allows the left and right drive shafts 910 to be controlled independently. This avoids mutual interference between the left and right wheel ends to a certain extent, facilitates vehicle steering, and also helps to improve the vehicle's acceleration performance.

[0096] In summary, the motor module 200 can be arranged as a single motor or as two symmetrical motors. When the motor module 200 is arranged as two motors, the motor module 200 can drive both wheel ends independently to ensure the running performance of the wheels.

[0097] In some embodiments, the drive shaft 910 and the motor module 200 are connected by a spline, thereby achieving a fixed connection between the drive shaft 910 and the motor module 200.

[0098] In some embodiments, the air intake of the engine 110 is located below the engine 110.

[0099] It should be noted that air flows downwards due to gravity in nature. Based on this, by placing the air intake of the engine 110 at the bottom of the engine 110, this natural flow characteristic can be utilized to make it easier for air to be drawn into the engine 110, reducing the need for additional power (such as a fan or pump) in the intake system, thereby improving the intake efficiency of the engine 110.

[0100] Furthermore, by placing the air intake of the engine 110 below the engine 110, the possibility of inhaling dust, sand, and other debris can be reduced, thereby avoiding damage to the engine 110's air intake system to a certain extent, ensuring the performance of the engine 110, and extending the service life of the engine 110.

[0101] In summary, by placing the air intake of engine 110 at the bottom, the smooth air intake of engine 110 can be ensured, and the performance and reliability of engine 110 can be improved.

[0102] In some embodiments, the exhaust port of the engine 110 is located above the engine 110. That is, the air intake and exhaust ports of the engine 110 are located on the upper and lower sides of the engine 110, respectively. This not only makes reasonable use of the space on the upper and lower sides of the engine 110, but also facilitates the arrangement of the subsequent intake assembly 300 and exhaust assembly 400, and improves the smoothness of exhaust.

[0103] In summary, the engine 110 in some embodiments of this disclosure is configured with an upper exhaust and lower intake configuration to ensure smooth intake and exhaust of the engine 110.

[0104] In some embodiments, the engine 110 may also be configured as a bottom exhaust and top intake configuration, or a front intake and rear exhaust configuration, or a front exhaust and rear intake configuration, without limitation.

[0105] In some embodiments, the engine 110 is a horizontally opposed engine 110, which allows the pistons of the engine 110 to be evenly distributed on both sides of the crankshaft and to move left and right in the horizontal direction. This reduces the overall height and length of the engine 110, which helps to reduce the space occupied by the drive assembly in the vertical direction, thereby reducing the height of the drive assembly, reducing the difficulty of the drive assembly layout, and also lowering the center of gravity of the vehicle, making the vehicle ride more smoothly.

[0106] In other words, by setting the engine 110 as a horizontally opposed engine 110, it is beneficial to reduce the height of the drive assembly, thereby reducing the space occupied by the drive assembly in the height direction of the vehicle. This is more conducive to the layout of the engine compartment for models with smaller height space.

[0107] In some embodiments, as shown in Figures 1 and 7, the drive assembly 1001 further includes a water pump 700 located on one side of the engine 110 in the height direction of the vehicle.

[0108] For example, by setting up a water pump 700, it can be ensured that the coolant can circulate in the cooling system, so that the coolant can continuously circulate through the cylinder block of the engine 110, carry away the heat of the engine 110, prevent the engine 110 from overheating, and ensure the normal operating temperature of the engine 110, thereby ensuring the working performance of the engine 110 and helping to extend the service life of the engine 110.

[0109] Meanwhile, by setting the water pump 700 to one side of the engine 110 in the height direction of the vehicle, it is not only convenient to reduce the size of the drive assembly, but also to allow the water pump 700 to be set close to the engine 110, so as to make it convenient to use the water pump 700 to control the coolant to remove the heat from the engine 110 and prevent the engine 110 from overheating.

[0110] For example, the above-mentioned water pump 700 being located on one side of the engine 110 in the height direction of the vehicle means that the water pump 700 is located on the upper side of the engine 110; or, the water pump 700 is located on the lower side of the engine 110.

[0111] In some embodiments, as shown in FIG1, in the height direction of the vehicle, the water pump 700 is located on the side of the engine 110 away from the motor module 200, thereby enabling the water pump 700 to be located on the upper side of the engine 110. This ensures that the water pump 700 and the engine 110 can be arranged vertically, while also preventing the water pump 700 located near the motor module 200 from occupying the space below the motor module 200. This allows the air intake of the engine 110 to be located below the engine 110, improving the air intake efficiency of the engine 110.

[0112] In some embodiments, in the height direction of the vehicle, the water pump 700 may also be located on the side of the engine 110 facing the motor module 200, so that the water pump 700 is located on the lower side of the engine 110. This also ensures that the water pump 700 and the engine 110 can be arranged in the vertical direction, which is beneficial to reducing the volume of the drive assembly.

[0113] The following description, with reference to the accompanying drawings, describes a power system 1000 according to some embodiments of the present disclosure.

[0114] As shown in Figures 1, 2 and 3, the power system 1000 according to some embodiments of the present disclosure includes: a drive assembly 1001, an intake assembly 300 and an exhaust assembly 400.

[0115] For example, the drive assembly 1001 is the aforementioned drive assembly 1001, and the structure of the drive assembly 1001 will not be described in detail here.

[0116] The intake assembly 300 is connected to the intake port of the engine 110, and the exhaust assembly 400 is connected to the exhaust port of the engine 110. The intake assembly 300 and the exhaust assembly 400 can be used together to realize the intake and exhaust of the engine 110, reducing the difficulty of intake and exhaust of the engine 110, thereby ensuring the working performance of the engine 110 to a certain extent.

[0117] As can be seen from the above structure, the power system 1000 of some embodiments of this disclosure can improve the integration of the power system 1000 by adopting the aforementioned drive assembly 1001, thereby reducing the volume of the power system 1000, that is, reducing the space occupied by the power system 1000, and thus reducing the difficulty of arranging the power system 1000.

[0118] It should be noted that, due to the reduced size of the power system 1000, the power system 1000 can be arranged as a whole in the front or rear compartment of the vehicle, improving the overall space utilization of the vehicle, which is beneficial to the arrangement of related structural components of the vehicle chassis, and can make the chassis layout simple and beautiful.

[0119] It should be noted that, with the above configuration, when the power system 1000 is applied to hybrid or pure electric vehicles, the small space occupied by the power system 1000 allows for the provision of space for the battery pack of the hybrid or pure electric vehicle, which is beneficial to increasing the capacity of the battery pack and thus improving the driving range of the hybrid or pure electric vehicle. Furthermore, due to the increased capacity of the battery pack, the battery packs of hybrid and pure electric vehicles can be interchanged, enabling the common platform production of battery packs for hybrid and pure electric vehicles.

[0120] Furthermore, by installing the power system 1000 of some embodiments of this disclosure on the vehicle, the battery pack can be highly integrated with the chassis, thereby improving the torsional strength of the entire vehicle.

[0121] In some embodiments, the drive assembly has a first space and a second space arranged in the height direction of the vehicle, a first motor 120, at least a portion of the engine 110 and a controller 800 are disposed in the first space, and a motor module 200 is disposed in the second space; an intake assembly 300 is disposed in the first space, thereby allowing the intake assembly 300 to be disposed close to the first motor 120 and the engine 110.

[0122] In this way, while reducing the difficulty of connecting the intake assembly 300 and the engine 110, it also allows multiple structural components of the power system 1000 to be integrated into a whole, which is conducive to improving the integration of the power system 1000. This reduces the size of the power system 1000, thereby reducing the space occupied by the power system 1000 and reducing the difficulty of arranging the power system 1000.

[0123] In other words, the power system 1000 in some embodiments of this disclosure not only integrates the drive assembly but also integrates the intake assembly 300 to maximize the integration of the power system 1000, thereby reducing the volume of the power system 1000, that is, reducing the space occupied by the power system 1000 and reducing the difficulty of arranging the power system 1000.

[0124] In summary, the power system 1000 of some embodiments of this disclosure arranges the engine 110 and the first motor 120 of the drive assembly in a front-to-back arrangement, arranges the first motor 120, the motor module 200 and the controller 800 in a vertical arrangement, and sets the intake assembly 300 close to the first motor 120 and the engine 110 to maximize the integration of the power system 1000 and improve the integration degree of the power system 1000. This allows the power system 1000 to be integrated into a whole and limited to a certain length, width and height range, reducing the volume of the power system 1000 and thus reducing the difficulty of arranging the power system 1000.

[0125] It is understood that, compared with related technologies, the power system 1000 of some embodiments of this disclosure not only integrates the drive assembly 1001, but also integrates the intake assembly 300, so as to maximize the integration of the power system 1000, reduce the space occupied by the power system 1000, thereby reducing the difficulty of arranging the power system 1000, and making room for the installation of the battery pack, which facilitates the increase of the battery pack capacity.

[0126] In some embodiments, as shown in FIG1, at least a portion of the intake assembly 300 is located on one side of the engine 110 in the length direction of the vehicle, thereby enabling at least a portion of the intake assembly 300 to be positioned close to the engine 110 in the length direction of the vehicle, that is, ensuring that at least a portion of the intake assembly 300 can be arranged with the drive assembly in the length direction of the vehicle, thereby improving the integration of the power system 1000.

[0127] In some embodiments, as shown in Figures 1, 2 and 3, the intake assembly 300 includes an air filter 310 and an intercooler 320, which are respectively disposed on both sides of the first motor 120 in the width direction of the vehicle. The air filter 310 is connected to the air intake of the engine 110 through the intercooler 320.

[0128] In other words, the air filter 310, intercooler 320 and first motor 120 are arranged in the width direction of the vehicle. This can make rational use of the space on one side of the engine 110, improve the integration of the power system 1000, and to a certain extent avoid increasing the volume of the power system 1000 too much due to the air filter 310 and intercooler 320, and reduce the difficulty of arranging the power system 1000.

[0129] Furthermore, by placing the air filter 310 and the intercooler 320 on both sides of the first motor 120 in the width direction of the vehicle, it is possible to ensure that the air filter 310 and the intercooler 320 can be placed on the outer periphery of the engine 110, while also allowing the air filter 310 and the intercooler 320 to occupy the space on the same side of the engine 110 at the same time.

[0130] Compared to placing the air filter 310 and intercooler 320 on both sides of the engine 110, this method makes it easier to reduce the space occupied by the power system 1000 in the length direction of the vehicle, which is beneficial to reducing the size of the power system 1000 in the length direction of the vehicle, thereby reducing the space occupied by the power system 1000 and reducing the difficulty of arranging the power system 1000.

[0131] Furthermore, by placing the air filter 310 and the intercooler 320 on opposite sides of the first motor 120 in the width direction of the vehicle, the air filter 310 and the intercooler 320 can be positioned close to the engine 110, reducing the difficulty of connecting the air filter 310, the intercooler 320 and the engine 110.

[0132] By configuring the air filter 310 to connect to the air intake of the engine 110 through the intercooler 320, it can be ensured that the air flowing to the engine 110 can flow through the air filter 310 and the intercooler 320 in sequence.

[0133] For example, when air flows through the air filter 310, the air filter 310 filters the air flowing through it to remove dust, sand particles and other impurities in the air, thereby protecting the engine 110; when air flows through the intercooler 320, the intercooler 320 cools the air flowing through it. The cooled air enters the engine 110, which can prevent the engine 110 from being damaged or even stalled due to excessively high air temperature, thereby ensuring the working performance of the engine 110 and extending the service life of the engine 110.

[0134] In some embodiments, as shown in FIG3, the air filter 310 has an air filter inlet 311, through which the air filter 310 is connected to the outside air, so that the outside air can enter the interior of the air filter 310 through the air filter inlet 311, so as to achieve the purpose of filtering the air using the air filter 310.

[0135] In some embodiments, as shown in Figures 1, 2 and 3, the first motor 120 is arranged at the rear end of the engine 110 and close to the middle of the engine 110. The air filter 310 and the intercooler 320 are arranged on both sides of the first motor 120 in the width direction of the vehicle and do not exceed the left and right boundaries of the first motor 120 and the motor module 200, so as to make full use of the space at the rear end of the engine 110 and improve the integration of the power system 1000.

[0136] In some embodiments, as shown in Figures 1, 2 and 3, the intake assembly 300 further includes a first connecting pipe 321, through which the intercooler 320 is connected to the air intake of the engine 110, thereby enabling the intercooler 320 to communicate with the air intake of the engine 110, thus ensuring that the air flowing to the engine 110 can flow sequentially through the air filter 310 and the intercooler 320.

[0137] In some embodiments, the first connecting pipe 321 is connected to the throttle valve 113 of the engine 110 so that the air discharged from the intercooler 320 can enter the intake manifold 112 of the engine 110 through the throttle valve 113, and finally enter the interior of the engine 110 through the intake manifold 112 to complete the intake of the engine 110.

[0138] In some embodiments, as shown in Figures 1, 2 and 3, the intake assembly 300 includes an intercooler muffler 322 connected between the air filter 310 and the intercooler 320. When the air filter 310 delivers air to the intake port of the engine 110 through the intercooler 320, the air can flow through the intercooler muffler 322. The intercooler muffler 322 is used to reduce the noise generated by the intake assembly 300 during the intake process, thereby improving the operating performance of the intake assembly 300.

[0139] In some embodiments, as shown in Figures 1 and 4, the exhaust assembly 400 and the engine 110 are arranged along the height direction of the vehicle, which allows the exhaust assembly 400 to be positioned close to the engine 110. This reduces the difficulty of connecting the exhaust assembly 400 and the engine 110, and further allows multiple structural components of the power system 1000 to be integrated into a whole, which is beneficial to improving the integration of the power system 1000. This reduces the volume of the power system 1000, thereby reducing the space occupied by the power system 1000 and reducing the difficulty of arranging the power system 1000.

[0140] In other words, the power system 1000 in some embodiments of this disclosure not only integrates the drive assembly, but also integrates the intake assembly 300 and the exhaust assembly 400, so as to maximize the integration of the power system 1000, thereby reducing the volume of the power system 1000, that is, reducing the space occupied by the power system 1000 and reducing the difficulty of arranging the power system 1000.

[0141] In summary, in some embodiments of this disclosure, the power system 1000 arranges the engine 110 and the first motor 120 of the drive assembly in a front-to-back arrangement, arranges the first motor 120, the motor module 200 and the controller 800 in a vertical arrangement, and sets the intake assembly 300 and the exhaust assembly 400 close to the engine 110. This maximizes the integration of the power system 1000 and improves its integration level. In this way, the power system 1000 can be integrated into a whole and limited to a certain length, width and height range, reducing the volume of the power system 1000 and thus reducing the difficulty of arranging the power system 1000.

[0142] In some embodiments, as shown in Figures 1 and 4, the exhaust assembly 400 includes a catalyst 410 and a muffler 420, which are respectively disposed on both sides of the engine 110 in the height direction of the vehicle. The muffler 420 is connected to the exhaust port of the engine 110 through the catalyst 410.

[0143] For example, by placing the catalytic converter 410 and the muffler 420 on opposite sides of the engine 110 in the vehicle's height direction, it can be ensured that the catalytic converter 410 and the muffler 420 can make full use of the space of the power system 1000 in the vehicle's height direction, avoiding an increase in the size of the power system 1000 due to the placement of the catalytic converter 410 and the muffler 420, improving the integration of the power system 1000, thereby reducing the volume of the power system 1000 and reducing the difficulty of arranging the power system 1000.

[0144] Meanwhile, by configuring the muffler 420 to connect to the exhaust port of the engine 110 through the catalytic converter 410, it can be ensured that the air discharged from the engine 110 can flow through the catalytic converter 410 and the muffler 420 in sequence.

[0145] For example, when air flows through the catalytic converter 410, the catalytic converter 410 is used to purify the air flowing through it, thereby reducing the emission of harmful gases and alleviating the burden on the environment and humans; when air flows through the muffler 420, the muffler 420 is used to reduce the noise of the air flowing through it, thereby reducing airflow noise, improving the user experience, and thus ensuring the working performance of the power system 1000.

[0146] In some embodiments, as shown in Figures 1 and 4, the exhaust assembly 400 includes a second connecting pipe 930, through which the catalyst 410 is connected to the exhaust port of the engine 110, thereby enabling the muffler 420 to be connected to the exhaust port of the engine 110 through the catalyst 410, thereby ensuring that the air discharged from the engine 110 can flow sequentially through the catalyst 410 and the muffler 420.

[0147] In some embodiments, the second connecting pipe 930 is connected to the exhaust manifold 114 of the engine 110 (the structure of the exhaust manifold 114 can be seen in Figure 6). The exhaust manifold 114 is connected to the exhaust port of the engine 110, thereby enabling the catalytic converter 410 to receive the exhaust gas of the engine 110, which facilitates the purification of the exhaust gas discharged from the engine 110.

[0148] In some embodiments, the second connecting pipe 930 is fixedly connected to the exhaust manifold 114 of the engine 110 by bolts to ensure the connection strength between the catalytic converter 410 and the engine 110 and facilitate the exhaust of air.

[0149] In some embodiments, as shown in Figures 1, 4, 5 and 7, the muffler 420 includes a first muffler 421 and a second muffler 422 that are interconnected. The first muffler 421 is connected to the catalyst 410, and the second muffler 422 has an exhaust outlet 4221.

[0150] For example, by configuring the muffler 420 to include a first muffler 421 and a second muffler 422 that are interconnected, the first muffler 421 and the second muffler 422 can work together to reduce noise, thereby increasing the volume of the muffler 420 and effectively reducing airflow noise, which means ensuring the working performance of the muffler 420.

[0151] In some embodiments, the air discharged from the catalytic converter 410 first flows through the first muffler 421 for noise reduction, and the air after being silenced by the first muffler 421 then enters the second muffler 422 through the third connecting pipe 430 for noise reduction, and the air after being silenced by the second muffler 422 is discharged through the exhaust outlet 4221 to complete the exhaust of the engine 110.

[0152] In some embodiments, as shown in Figures 1 and 4, the first muffler 421 and the second muffler 422 are spaced apart on both sides of the motor module 200 in the length direction of the vehicle, thereby making full use of the space of the power system 1000 in the length direction of the vehicle and improving the integration of the power system 1000.

[0153] In some embodiments, as shown in Figures 1 and 4, the first muffler 421 is located on the front side of the motor module 200, and the second muffler 422 is located on the rear side of the motor module 200. This arrangement not only allows the first muffler 421 and the second muffler 422 to be spaced apart on both sides of the motor module 200 along the length of the vehicle, but also allows the exhaust outlet 4221 of the second muffler 422 to be located close to the tailpipe of the vehicle to facilitate the discharge of exhaust gas.

[0154] In some embodiments, as shown in Figures 1 and 4, the catalyst 410 is arranged on top of the engine 110.

[0155] It should be noted that, since the first muffler 421 and the second muffler 422 are spaced apart on both sides of the motor module 200 in the length direction of the vehicle, the first muffler 421 and the second muffler 422 are positioned close to the bottom of the engine 110. By arranging the catalytic converter 410 on the top of the engine 110, the catalytic converter 410 and the muffler 420 are respectively located on both sides of the engine 110 in the height direction of the vehicle. This fully utilizes the space on both sides of the engine 110 in the vertical direction, improves the integration of the power system 1000, thereby reducing the size of the power system 1000 and reducing the difficulty of arranging the power system 1000.

[0156] In some embodiments, as shown in Figures 4, 5 and 7, a third connecting pipe 430 is provided between the first muffler 421 and the second muffler 422. The third connecting pipe 430 connects the first muffler 421 and the second muffler 422 respectively, thereby realizing the mutual connection between the first muffler 421 and the second muffler 422 to improve the noise reduction effect of the muffler 420.

[0157] In some embodiments, as shown in Figures 4, 5, and 7, the third connecting pipe 430 includes two pipes, which are spaced apart on both sides of the motor module 200 in the width direction of the vehicle. While enabling communication between the first muffler 421 and the second muffler 422, the space of the powertrain 1000 in the width direction of the vehicle can be fully utilized, improving the integration of the powertrain 1000.

[0158] In some embodiments, as shown in Figures 1 and 7, the power system 1000 further includes a turbocharger 600, which includes a compressor 610 and a turbine 620. The compressor 610 is connected to the intake assembly 300, and the turbine 620 is connected to the exhaust assembly 400, thereby improving the intake and exhaust performance of the power system 1000 and improving the working performance of the power system 1000 to a certain extent.

[0159] In some embodiments, as shown in Figures 1 and 4, in the height direction of the vehicle, the compressor 610 and the turbine 620 are both located on the side of the engine 110 away from the motor module 200.

[0160] In this way, while placing the compressor 610 and turbine 620 on the outer periphery of the engine 110, the compressor 610 can also be placed close to the air filter 310 and intercooler 320, and the turbine 620 can be placed close to the catalytic converter 410 and muffler 420. This facilitates the connection between the compressor 610 and the air filter 310 and the intercooler 320, and between the turbine 620 and the catalytic converter 410 and the muffler 420, respectively. This improves the integration of the power system 1000 and reduces the difficulty of connecting the various components in the power system 1000, thereby reducing the assembly difficulty of the power system 1000.

[0161] In some embodiments, the compressor 610 is connected to the air filter 310 and the intercooler 320, respectively, and the turbine 620 is connected to the catalytic converter 410 and the muffler 420, respectively.

[0162] For example, by connecting the compressor 610 to the air filter 310 and the intercooler 320 respectively, it can be ensured that the air flowing through the intercooler 320 can flow through the compressor 610. When the air flows through the compressor 610, the compressor 610 is used to increase the air pressure, thereby increasing the air pressure inside the engine 110, ensuring the thermal efficiency of the engine 110, that is, ensuring the working performance of the engine 110.

[0163] Furthermore, by connecting the turbine 620 to the catalytic converter 410 and the muffler 420 respectively, it can be ensured that the air flowing towards the muffler 420 can first flow through the turbine 620. When the air flows through the turbine 620, the turbine 620 is used to convert the kinetic energy of the air into mechanical energy, thereby achieving efficient use of energy.

[0164] In some embodiments, as shown in FIG1, the compressor 610 is positioned close to the intercooler 320, which facilitates the connection between the compressor 610 and the intercooler 320 and reduces the difficulty of connecting the compressor 610 and the intercooler 320.

[0165] In some embodiments, the compressor 610 may also be located close to the air filter 310 to reduce the difficulty of connecting the compressor 610 and the intercooler 320.

[0166] In some embodiments, as shown in Figures 1, 2, and 3, the turbocharger 600 further includes a fourth connecting pipe 312 and a fifth connecting pipe. The air filter 310 is connected to the inlet of the compressor 610 through the fourth connecting pipe 312, and the intercooler 320 is connected to the outlet of the compressor 610 through the fifth connecting pipe. In this way, the air filtered by the air filter 310 can flow to the compressor 610 along the fourth connecting pipe 312. The compressor 610 is used to pressurize the filtered air. After pressurization, the air enters the intercooler 320 through the fifth connecting pipe. After being cooled by the intercooler 320, the air enters the throttle valve 113 through the first connecting pipe 321, then enters the intake manifold 112 of the engine 110, and finally enters the interior of the engine 110 to complete the intake of the engine 110.

[0167] In some embodiments, as shown in Figures 1, 2 and 3, a fourth connecting pipe 312 is arranged between the first motor 120 and the motor module 200, and the fourth connecting pipe 312 extends along the outer peripheral wall of the first motor 120.

[0168] For example, the fourth connecting pipe 312 extends adaptively along the shape of the first motor 120. This not only makes reasonable use of the space between the first motor 120 and the motor module 200, but also avoids increasing the distance between the first motor 120 and the motor module 200 due to the setting of the fourth connecting pipe 312. This reduces the size of the power system 1000 in the vertical direction and improves the integration of the power system 1000.

[0169] In some embodiments, as shown in Figures 1, 2 and 3, the fourth connecting pipe 312 is arranged between the first motor 120 and the controller 800. While arranging the fourth connecting pipe 312 between the first motor 120 and the motor module 200, it also allows the fourth connecting pipe 312 to be located close to the air filter 310. This facilitates connecting the air filter 310 and the compressor 610 using the fourth connecting pipe 312, reducing the difficulty of connecting the air filter 310 and the compressor 610.

[0170] In some embodiments, as shown in Figures 4 and 5, the turbocharger 600 further includes a sixth connecting pipe 940 and a muffler intake pipe 4211. The catalytic converter 410 is connected to the inlet of the turbine 620 through the sixth connecting pipe 940, and the inlet of the muffler 420 is connected to the outlet of the turbine 620 through the muffler intake pipe 4211. In this way, the air purified by the catalytic converter 410 can flow to the turbine 620 along the sixth connecting pipe 940. The turbine 620 is used to convert the kinetic energy of the air into mechanical energy. Subsequently, the air in the turbine 620 enters the interior of the muffler 420 through the muffler intake pipe 4211.

[0171] In the description of some embodiments of this disclosure, features defined with "first", "second", "third", "fourth", "fifth" and "sixth" may explicitly or implicitly include one or more of these features, used to distinguish and describe features, without any order or importance.

[0172] In some embodiments, as shown in Figures 4 and 5, the muffler intake pipe 4211 is connected to the first muffler 421, so that the air from the turbine 620 can enter the interior of the first muffler 421 through the muffler intake pipe 4211. The air entering the interior of the first muffler 421 can enter the interior of the second muffler 422 through the two third connecting pipes 430 on the left and right, and finally be discharged into the atmosphere through the exhaust port 4221 of the second muffler 422 to complete the exhaust of the engine 110.

[0173] In some embodiments, the sixth connecting pipe 940 is connected to the turbine 620 via a flange to ensure the connection strength between the sixth connecting pipe 940 and the turbine 620, thereby enabling the catalyst 410 to communicate with the turbine 620 and facilitating the exhaust of air.

[0174] In some embodiments, the muffler intake pipe 4211 and the turbine 620 are connected by clamps to ensure the connection strength between the muffler intake pipe 4211 and the turbine 620, thereby realizing the connection between the first muffler 421 and the turbine 620 and facilitating the exhaust of air.

[0175] In some embodiments, as shown in Figures 1 and 4, the turbine 620 and the compressor 610 are spaced apart along the length of the vehicle and are interconnected.

[0176] For example, by spaced apart from the turbine 620 and the compressor 610 along the length of the vehicle, the compressor 610 can be positioned away from the turbine 620, thereby reducing the impact of the exhaust heat from the turbine 620 on the intake of the compressor 610 and ensuring the working performance of the compressor 610.

[0177] Furthermore, by connecting the turbine 620 and the compressor 610 together, when the turbine 620 rotates, it can drive the compressor 610 to rotate, which helps to increase the speed of the compressor 610 and thus improve the intake performance of the intake assembly 300.

[0178] In some embodiments, as shown in Figures 1 and 7, a connecting shaft 630 is provided between the turbine 620 and the compressor 610. The connecting shaft 630 connects the turbine 620 and the compressor 610 respectively, thereby enabling the turbine 620 and the compressor 610 to be connected to each other and reducing the difficulty of connecting the turbine 620 and the compressor 610.

[0179] It should be noted that the interconnection between the turbine 620 and the compressor 610 mentioned here means that the rotating shaft of the turbine 620 is connected to the rotating shaft of the compressor 610, so that the turbine 620 can drive the compressor 610 to rotate.
