[0071] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0072] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0073] The drive assembly of the embodiments of the present utility model will be described below with reference to the accompanying drawings of the specification.

[0074] Combined with Figure 1 、 Figure 2 And Figure 3 As shown in, the drive assembly according to the embodiments of the present utility model includes: an engine 110, a first motor 120, a motor module 200, and a controller 800.

[0075] Among them, as Figure 1 And Figure 4 As shown in, the engine 110 and the first motor 120 are arranged along the length direction of the vehicle. It should be noted that the length direction of the vehicle mentioned here can also be understood as the direction between the head and the tail of the vehicle, that isFigure 1 and Figure 4 In the front - rear direction shown in Figure 4 , that is, the engine 110 and the first motor 120 are arranged along the front - rear direction of the drive assembly. In this way, the space of the drive assembly in the front - rear direction can be rationally utilized, and the space of the drive assembly in the up - down direction and / or left - right direction is avoided from increasing due to the arrangement of the engine 110 and the first motor 120, which is beneficial to reducing the size of the drive assembly in the up - down direction and / or left - right direction.

[0076] Combined Figure 1 and Figure 3 As shown, the first motor 120, the motor module 200, and the controller 800 are arranged along the height direction of the vehicle. It should be noted that the height direction of the vehicle mentioned here can be understood as the direction between the vehicle floor and the vehicle roof, that is Figure 1 and Figure 3 In the up - down direction shown in Figure 3 , that is, 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 up - down direction of the drive assembly. Compared with arranging the motor module 200 and the first motor 120 along the length direction of the vehicle, the occupied space of the drive assembly in the front - rear direction can be reduced. And because the engine 110 and the first motor 120 are arranged along the front - rear direction of the drive assembly, after arranging the first motor 120, the motor module 200, and the controller 800 along the up - down direction of the drive assembly, the overall structure of the drive assembly can be arranged along both the front - rear direction and the up - down direction, to a certain extent, avoiding the drive assembly occupying a large front - rear direction space and a large up - down direction space, which is beneficial to reducing the volume of the drive assembly and reducing the layout difficulty of the drive assembly.

[0077] It should also 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 vacate the space below the engine 110, which is beneficial to arranging the air inlet of the engine 110 and the oil pan 111 below the engine 110 to ensure the smoothness of the engine 110's air intake. On the other hand, because the first motor 120 and the motor module 200 need to be electrically connected to the controller 800, therefore, arranging the first motor 120, the motor module 200, and the controller 800 along the height direction of the vehicle can also enable the controller 800 to be arranged close to the first motor 120 and the motor module 200, which is convenient to reduce the electrical connection difficulty between the controller 800 and the first motor 120 and the motor module 200 respectively, and is beneficial to ensuring the working performance of the first motor 120 and the motor module 200.

[0078] As can be seen from the above structure, in the drive assembly according to the embodiment of the present utility model, the engine 110 and the first motor 120 are arranged front and rear, and the first motor 120, the motor module 200 and the controller 800 are arranged vertically, so as to maximize the integration of the drive assembly and improve the integration degree of the drive assembly. In this way, the drive assembly can be integrated into a whole and limited within a certain range of length, width and height, reducing the volume of the drive assembly, thereby reducing the layout difficulty of the drive assembly.

[0079] Meanwhile, due to the reduction in the volume of the drive assembly, the drive assembly can be integrally arranged in the front cabin or the rear cabin of the whole vehicle, improving the space utilization rate of the whole vehicle, facilitating the layout of the relevant structural parts of the vehicle chassis, and making the chassis layout simple and beautiful.

[0080] It should also be noted that through the above settings, when the drive assembly is applied to a hybrid vehicle or a pure electric vehicle, due to the small occupied space of the drive assembly, the drive assembly can make room for the battery pack of the hybrid vehicle or the pure electric vehicle, which is beneficial to increasing the capacity of the battery pack, thereby increasing the cruising range of the hybrid vehicle or the pure electric vehicle. Moreover, due to the increase in the capacity of the battery pack, the battery packs of the hybrid vehicle and the pure electric vehicle can be interchanged, realizing the co-platform production of the battery packs of the hybrid vehicle and the pure electric vehicle.

[0081] In addition, by arranging the drive assembly of the present application on the vehicle, the battery pack can be highly integrated with the chassis, improving the torsional strength of the whole vehicle.

[0082] It can be understood that compared with the prior art, the drive assembly of the present application 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 degree of the drive assembly, reduce the occupied space of the drive assembly, thereby reducing the layout difficulty of the drive assembly and making room for the installation of the battery pack, facilitating the increase of the capacity of the battery pack.

[0083] In some embodiments, in combination with Figure 1 、 Figure 2 and Figure 3As shown, the controller 800 is provided between the motor module 200 and the first motor 120. That is to say, after arranging the first motor 120, the motor module 200, and the controller 800 in the height direction of the vehicle, the controller 800 is also provided between the motor module 200 and the first motor 120, so that in the height direction of the vehicle, the first motor 120, the controller 800, and the motor module 200 are arranged in sequence. On the one hand, this can rationally utilize the space of the drive assembly in the up and down directions and avoid increasing the space of the drive assembly in the front and back directions due to the setting of the controller 800, which is beneficial to reducing the occupied space of the drive assembly in the front and back directions, reducing the layout difficulty of the drive assembly, and facilitating making room for the battery pack of hybrid vehicles and pure electric vehicles, which is beneficial to ensuring the capacity of the battery pack and realizing the improvement of the cruising range of hybrid vehicles and pure electric vehicles. On the other hand, it can also enable the controller 800 to be arranged close to both the first motor 120 and the motor module 200 at the same time, 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.

[0084] At the same time, by arranging the controller 800 between the motor module 200 and the first motor 120, the motor module 200 and the first motor 120 can also be used to cooperate to protect the controller 800 and extend the service life of the controller 800.

[0085] In some embodiments, the controller 800 is electrically connected to the first motor 120 and the motor module 200, so as to facilitate using the controller 800 to control the operation of the first motor 120 and the motor module 200 to ensure the working performance of the first motor 120 and the motor module 200, and further ensure the working performance of the drive assembly.

[0086] In a specific example, 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 working conditions such as the driver's requirements and the vehicle state to meet the needs of the driving conditions.

[0087] It should be noted that electrically connecting the controller 800 to the first motor 120 and the motor module 200 at the same time can be understood as integrating the controllers of the first motor 120 and the motor module 200 in the present application to form the controller 800, and placing the controller 800 between the first motor 120 and the motor module 200 without occupying other spaces of the drive assembly, making full use of the space and making the integration degree of the drive assembly higher.

[0088] In some embodiments, in combination with Figure 1 、 Figure 2 and Figure 3As shown, there is a cavity between the first motor 120 and the motor module 200, and the cavity is used to accommodate the controller 800. This facilitates the installation of the controller 800 between the motor module 200 and the first motor 120, reducing the assembly difficulty of the controller 800.

[0089] 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. The controller 800 is disposed in the cavity, thereby realizing the installation of the controller 800 between the motor module 200 and the first motor 120 and reducing the assembly difficulty of the controller 800.

[0090] In some embodiments, as Figure 1 shown, in the height direction of the vehicle, the motor module 200 is disposed below the first motor 120. Since the motor module 200 needs to be connected to the vehicle wheel through the transmission shaft 910, by disposing the motor module 200 below the first motor 120, it can be ensured that the motor module 200 is close to the wheel, so that the transmission shaft 910 can be close to the wheel, enabling the angle between the transmission shaft 910 and the wheel to be within the allowable angle range, which is beneficial to the connection between the transmission shaft 910 and the wheel and ensures the working performance of the wheel.

[0091] In some embodiments, in combination with Figure 1 、 Figure 2 and Figure 3 shown, the controller 800 has a first outer surface facing the first motor 120 and a second outer surface facing the motor module 200. The first outer surface is consistent with the extension direction of the outer wall surface of the first motor 120 facing it, and the second outer surface is consistent with the extension direction of the outer wall surface of the motor module 200 facing it. Here, it means that 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, 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, and the extensions of the two outer surfaces of the controller 800 and the first motor 120 facing each other are consistent, and the extensions of the two outer surfaces of the controller 800 and the motor module 200 facing each other are consistent. Thus, the controller 800 can reasonably utilize the space between the first motor 120 and the motor module 200. While ensuring that the controller 800 can be effectively installed between the first motor 120 and the motor module 200, it can also, to a certain extent, avoid excessively increasing the distance between the first motor 120 and the motor module 200 due to the installation of the controller 800, that is, avoid excessively increasing the size of the drive assembly in the up and down direction, which is beneficial to reducing the volume of the drive assembly and the layout difficulty of the drive assembly.

[0092] In some embodiments, the first motor 120 is a generator, and the motor module 200 includes a drive motor. To ensure the working performance of the first motor 120 and the motor module 200 to a certain extent, and thus ensure the working performance of the drive assembly.

[0093] In some embodiments, as Figure 1 shown, 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, through the above arrangement, the output shaft of the first motor 120 can be arranged close to the engine 110, which is beneficial to reducing the connection difficulty between the engine 110 and the first motor 120.

[0094] At the same time, through the above arrangement, it is also possible to avoid the first motor 120 occupying too much space in the up-down direction and / or the left-right direction to a certain extent, which is beneficial to reducing the volume of the drive assembly.

[0095] In some embodiments, the axis of the first motor 120 is parallel to the axis of the engine 110. That is to say, 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 connection difficulty between the engine 110 and the first motor 120.

[0096] In some embodiments, the engine 110 and the first motor 120 are fixedly connected. To ensure the connection strength between the engine 110 and the first motor 120, so that the relative positions of the engine 110 and the first motor 120 are stable. In this way, while ensuring the working performance of the engine 110 and the first motor 120, the structural stability of the drive assembly can also be improved.

[0097] Among them, the fixed connection between the engine 110 and the first motor 120 mentioned here can be that the outer shell of the engine 110 and the outer shell of the first motor 120 are fixedly connected by bolts, or the outer shell of the engine 110 and the outer shell of the first motor 120 are welded, bonded, etc.

[0098] In some embodiments, as Figure 1 shown, the first motor 120 is arranged at the rear end of the engine 110 and is arranged close to the middle in the left-right direction of the engine 110. In this way, while arranging the engine 110 and the first motor 120 along the length direction of the vehicle, the space at the rear end of the engine 110 can be reasonably utilized, which is convenient for arranging other structural parts at the rear end of the engine 110 subsequently, so as to facilitate reducing the volume of the drive assembly.

[0099] In some embodiments, the motor module 200 includes a driving motor, and the driving motor is respectively connected to two transmission shafts 910. The two transmission shafts 910 are arranged at intervals in the width direction of the vehicle, and the transmission shafts 910 are adapted to be connected to the wheel ends of the vehicle. Herein, the width direction of the vehicle can be understood as the direction between the driver's seat and the co-driver's seat of the vehicle, that is, Figure 1 the left-right direction shown in Figure 1 . That is to say, when the motor module 200 includes a driving motor, the driving motor is simultaneously connected to two transmission shafts 910 arranged at intervals in the left-right direction of the driving assembly. Since the transmission shafts 910 are adapted to be connected to the wheel ends of the vehicle, the motor module 200 can be used to drive the two wheel ends to act simultaneously in this way.

[0100] It should be noted that by simultaneously connecting two transmission shafts 910 with one driving motor, the structure of the motor module 200 can be simplified, thereby reducing the occupied space of the motor module 200, which is beneficial to reducing the volume of the driving assembly.

[0101] In some embodiments, the motor module 200 includes two driving motors, and each driving motor is respectively connected to one transmission shaft 910. The two transmission shafts 910 are arranged at intervals in the width direction of the vehicle, and the transmission shafts 910 are adapted to be connected to the wheel ends of the vehicle. That is to say, the motor module 200 is not limited to being arranged to include one driving motor. The motor module 200 can also include two driving motors. When the motor module 200 includes two driving motors, each driving motor is respectively connected to one transmission shaft 910. In this way, the motor module 200 can also be used to drive the two wheel ends to act simultaneously.

[0102] It should be noted that compared with connecting two transmission shafts 910 with one driving motor, each driving motor is respectively connected to one transmission shaft 910, which enables the left and right transmission shafts 910 to be independently controlled, avoids interference between the left and right wheel ends to a certain extent, facilitates vehicle steering, and is beneficial to improving the acceleration performance of the vehicle.

[0103] In summary, the motor module 200 can be arranged as a single motor or as a left-right symmetric dual motor. When the motor module 200 is arranged as a dual motor, the motor module 200 can independently drive the bilateral wheel ends to ensure the running performance of the wheels.

[0104] In some embodiments, the transmission shaft 910 and the motor module 200 are connected by splines to achieve the fixed connection between the transmission shaft 910 and the motor module 200.

[0105] In some embodiments, the intake port of the engine 110 is located below the engine 110. It should be noted that air will flow downward under the influence of gravity in nature. Based on this, by setting the intake port of the engine 110 below the engine 110, this natural flow characteristic can be utilized to make it easier for air to be inhaled into the engine 110, reducing the need for the intake system for additional power (such as a fan or a pump), thereby improving the intake efficiency of the engine 110.

[0106] At the same time, by locating the intake port of the engine 110 below the engine 110, the possibility of inhaling sundries such as dust and sand grains can also be reduced, thereby avoiding damage to the intake system of the engine 110 by the above-mentioned sundries to a certain extent, ensuring the performance of the engine 110, and extending the service life of the engine 110.

[0107] In summary, by setting the intake port of the engine 110 below, the smoothness of the engine 110's intake can be ensured, and the performance and reliability of the engine 110 can be improved.

[0108] In some embodiments, the exhaust port of the engine 110 is located above the engine 110. That is to say, the intake port and the exhaust port of the engine 110 are respectively located on the upper and lower sides of the engine 110. In this way, while rationally utilizing the space on the upper and lower sides of the engine 110, it is also beneficial to the layout of the subsequent intake assembly 300 and exhaust assembly 400, facilitating the improvement of the exhaust smoothness.

[0109] In summary, the engine 110 of the present application is formed in a way of upper exhaust and lower intake to ensure the smoothness of the engine 110's intake and exhaust.

[0110] Of course, in some other embodiments, the engine 110 can also be formed in a way of lower exhaust and upper intake, or, in a way of front intake and rear exhaust, or, in a way of front exhaust and rear intake, which is not specifically limited herein.

[0111] In some embodiments, the engine 110 is a horizontally opposed engine 110. To achieve the average distribution of the pistons of the engine 110 on both sides of the crankshaft and move left and right in the horizontal direction, so that the overall height of the engine 110 is reduced and the length is shortened, which is beneficial to reducing the occupied space of the drive assembly in the up and down directions, thereby achieving the reduction of the height dimension of the drive assembly, reducing the layout difficulty of the drive assembly, and also reducing the center of gravity of the whole vehicle, making the vehicle run more smoothly.

[0112] That is to say, by setting the engine 110 as a horizontally opposed engine 110, it is beneficial to reduce the height of the drive assembly, so that the drive assembly occupies less space in the height direction of the whole vehicle. In this way, for vehicle models with a small height space, it is more beneficial to the layout of the engine compartment.

[0113] In some embodiments, in combination Figure 1 and Figure 7 As shown, the drive assembly also includes a water pump 700, which is located on one side of the engine 110 in the height direction of the vehicle. The water pump 700 is provided to ensure that the coolant can circulate in the cooling system, so that the coolant can continuously circulate through the cylinder of the engine 110, take 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.

[0114] At the same time, by arranging the water pump 700 to be located on one side of the engine 110 in the height direction of the vehicle, it is convenient to reduce the volume of the drive assembly and at the same time enable the water pump 700 to be arranged close to the engine 110, so that it is convenient to use the water pump 700 to control the coolant to take away the heat of the engine 110 and prevent the engine 110 from overheating.

[0115] The water pump 700 mentioned above 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 .

[0116] In some embodiments, Figure 1 As shown, in the height direction of the vehicle, the water pump 700 is arranged on the side of the engine 110 away from the motor module 200. The water pump 700 is arranged on the upper side of the engine 110, so that the water pump 700 and the engine 110 can be arranged in the up-down direction, and the water pump 700 arranged close to the motor module 200 can be prevented from occupying the space below the motor module 200, so that the air intake of the engine 110 can be arranged below the engine 110, thereby improving the air intake efficiency of the engine 110.

[0117] Of course, in some other embodiments, in the height direction of the vehicle, the water pump 700 may also be arranged on the side of the engine 110 facing the motor module 200, so as to realize the arrangement of the water pump 700 on the lower side of the engine 110. This can also ensure that the water pump 700 and the engine 110 can be arranged in the up and down direction, which is beneficial to reduce the volume of the drive assembly.

[0118] The power system 1000 of an embodiment of the utility model is described below with reference to the accompanying drawings.

[0119] Combination Figure 1 , Figure 2 and Figure 3 As shown, the power system 1000 according to the embodiment of the present utility model includes: a drive assembly, an intake assembly 300 and an exhaust assembly 400 .

[0120] Among them, the drive assembly is the aforementioned drive assembly, and the specific structure of the drive assembly will not be elaborated here.

[0121] 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. This facilitates the intake and exhaust of the engine 110 by the cooperation of the intake assembly 300 and the exhaust assembly 400, reduces the difficulty of intake and exhaust of the engine 110, and thus ensures the working performance of the engine 110 to a certain extent.

[0122] As can be seen from the above structure, for the power system 1000 of the embodiment of the present invention, by adopting the aforementioned drive assembly, the integration degree of the power system 1000 can be improved, thereby reducing the volume of the power system 1000, that is, reducing the occupied space of the power system 1000, and further reducing the layout difficulty of the power system 1000.

[0123] It should be noted that due to the reduction in the volume of the power system 1000, the power system 1000 can be integrally arranged in the front compartment or the rear compartment of the whole vehicle, improving the space utilization rate of the whole vehicle, facilitating the layout of the relevant structural parts of the vehicle chassis, and making the chassis layout simple and beautiful.

[0124] It should also be noted that through the above settings, when the power system 1000 is applied to a hybrid vehicle or a pure electric vehicle, due to the small occupied space of the power system 1000, the power system 1000 can make room for the battery pack of the hybrid vehicle or the pure electric vehicle, which is beneficial to increasing the capacity of the battery pack, and further improving the cruising range of the hybrid vehicle or the pure electric vehicle. Moreover, due to the increase in the capacity of the battery pack, the battery packs of the hybrid vehicle and the pure electric vehicle can be interchanged, realizing the co-platform production of the battery packs of the hybrid vehicle and the pure electric vehicle.

[0125] In addition, by arranging the power system 1000 of the present application on the vehicle, the battery pack can also be highly integrated with the chassis, improving the torsional strength of the whole vehicle.

[0126] In some embodiments, the drive assembly has a first space and a second space arranged in the height direction of the vehicle. The first motor 120, at least part of the engine 110, and the controller 800 are arranged in the first space, and the motor module 200 is arranged in the second space; the intake assembly 300 is arranged in the first space. So that the intake assembly 300 can be arranged close to the first motor 120 and the engine 110. In this way, while reducing the connection difficulty between the intake assembly 300 and the engine 110, multiple structural parts of the power system 1000 can be integrated into a whole, which is beneficial to improving the integration degree of the power system 1000, reducing the volume of the power system 1000, and thus reducing the occupied space of the power system 1000 and the layout difficulty of the power system 1000.

[0127] That is to say, the power system 1000 of the present application not only integrates the drive assembly, but also integrates the intake assembly 300, so as to maximize the integration degree of the power system 1000, thereby reducing the volume of the power system 1000, that is, reducing the occupied space of the power system 1000 and lowering the layout difficulty of the power system 1000.

[0128] In summary, the power system 1000 of the present application arranges the engine 110 and the first motor 120 of the drive assembly front and back, arranges the first motor 120, the motor module 200 and the controller 800 up and down, and arranges the intake assembly 300 close to the first motor 120 and the engine 110, so as to maximize the integration of the power system 1000 and improve the integration degree of the power system 1000. In this way, the power system 1000 can be integrated into a whole and limited within a certain range of length, width and height, reducing the volume of the power system 1000, thereby lowering the layout difficulty of the power system 1000.

[0129] It can be understood that compared with the prior art, the power system 1000 of the present application not only integrates the drive assembly, but also integrates the intake assembly 300, so as to maximize the integration degree of the power system 1000, reduce the occupied space of the power system 1000, thereby lowering the layout difficulty of the power system 1000 and making room for the installation of the battery pack, which is convenient for increasing the capacity of the battery pack.

[0130] In some embodiments, such as Figure 1 shown, at least part of the intake assembly 300 is located on one side of the engine 110 in the vehicle length direction. So that in the vehicle length direction, at least part of the intake assembly 300 can be arranged close to the engine 110, that is, to ensure that at least part of the intake assembly 300 can be arranged in line with the drive assembly in the vehicle length direction, realizing the improvement of the integration degree of the power system 1000.

[0131] In some embodiments, in combination with Figure 1 、 Figure 2 and Figure 3As shown in the figure, the intake assembly 300 includes an air filter 310 and an intercooler 320. The air filter 310 and the intercooler 320 are respectively arranged on both sides of the first motor 120 in the vehicle width direction. The air filter 310 is communicated with the intake port of the engine 110 through the intercooler 320. That is to say, the air filter 310, the intercooler 320 and the first motor 120 are arranged in the vehicle width direction. In this way, the space on one side of the engine 110 can be rationally utilized, the integration degree of the power system 1000 can be improved, and to a certain extent, the volume of the power system 1000 can be prevented from being excessively increased due to the air filter 310 and the intercooler 320, and the layout difficulty of the power system 1000 can be reduced.

[0132] At the same time, by arranging the air filter 310 and the intercooler 320 on both sides of the first motor 120 in the vehicle width direction respectively, while ensuring that the air filter 310 and the intercooler 320 can be arranged on the outer periphery of the engine 110, it can also make the air filter 310 and the intercooler 320 occupy the space on the same side of the engine 110 at the same time. Compared with the situation where the air filter 310 and the intercooler 320 are respectively located on both sides of the engine 110, it is convenient to reduce the occupied space of the power system 1000 in the vehicle length direction, which is beneficial to reducing the size of the power system 1000 in the vehicle length direction, thereby reducing the occupied space of the power system 1000 and reducing the layout difficulty of the power system 1000.

[0133] In addition, by arranging the air filter 310 and the intercooler 320 on both sides of the first motor 120 in the vehicle width direction respectively, it can also make the air filter 310 and the intercooler 320 close to the engine 110, reducing the connection difficulty between the air filter 310, the intercooler 320 and the engine 110.

[0134] By setting the air filter 310 to be communicated with the intake port of the engine 110 through the intercooler 320, it can ensure that the air flowing to the engine 110 can flow through the air filter 310 and the intercooler 320 in sequence. Among them, when the air flows through the air filter 310, the air filter 310 is used to filter the air flowing through it to remove dust, sand particles and other impurities in the air, etc., so as to achieve the purpose of protecting the engine 110; when the air flows through the intercooler 320, the intercooler 320 is used to cool the air flowing through it, and the cooled air enters the engine 110, which can avoid the phenomenon that the engine 110 is damaged or even stalls due to too high air temperature, so as to ensure the working performance of the engine 110 and extend the service life of the engine 110.

[0135] In some embodiments, such as Figure 3As shown, the air filter 310 has an air filter intake port 311, and the air filter 310 communicates with the external air through the air filter intake port 311, so that the external air can enter the interior of the air filter 310 through the air filter intake port 311 on the air filter 310, so as to realize filtering the air by using the air filter 310.

[0136] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 3 As shown, the first motor 120 is arranged at the rear end of the engine 110 and is 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 vehicle width direction 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 degree of the power system 1000.

[0137] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 3 As shown, the intake assembly 300 further includes a first connecting pipe 321, and the intercooler 320 communicates with the intake port of the engine 110 through the first connecting pipe 321, so as to connect the intercooler 320 with the intake port of the engine 110, thereby ensuring that the air flowing to the engine 110 can flow through the air filter 310 and the intercooler 320 in sequence.

[0138] In a specific example, the first connecting pipe 321 communicates with 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.

[0139] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 3 As shown, the intake assembly 300 includes an intercooler muffler 322, and the intercooler muffler 322 is connected between the air filter 310 and the intercooler 320. In this way, when the air filter 310 conveys air towards 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 during the intake process of the intake assembly 300, so as to improve the working performance of the intake assembly 300.

[0140] In some embodiments, in combination with Figure 1 and Figure 4As shown, the exhaust assembly 400 and the engine 110 are arranged along the height direction of the vehicle. In this way, the exhaust assembly 400 can be arranged close to the engine 110, reducing the difficulty of connecting the exhaust assembly 400 and the engine 110. At the same time, it can further integrate multiple structural components of the power system 1000 into a whole, which is beneficial to improving the integration degree of the power system 1000. In this way, the volume of the power system 1000 can be reduced, thereby reducing the occupied space of the power system 1000 and lowering the layout difficulty of the power system 1000.

[0141] That is to say, the power system 1000 of the present application not only integrates the drive assembly, but also integrates the intake assembly 300 and the exhaust assembly 400 to maximize the integration degree of the power system 1000, thereby reducing the volume of the power system 1000, that is, reducing the occupied space of the power system 1000 and lowering the layout difficulty of the power system 1000.

[0142] In summary, in the power system 1000 of the present application, the engine 110 and the first motor 120 of the drive assembly are arranged front and back, the first motor 120, the motor module 200 and the controller 800 are arranged up and down, and the intake assembly 300 and the exhaust assembly 400 are arranged close to the engine 110 to maximize the integration of the power system 1000 and improve the integration degree of the power system 1000. In this way, the power system 1000 can be integrated into a whole and limited within a certain length, width and height range, reducing the volume of the power system 1000, thereby lowering the layout difficulty of the power system 1000.

[0143] In some embodiments, as shown in Figure 1 and Figure 4 , the exhaust assembly 400 includes a catalytic converter 410 and a muffler 420. The catalytic converter 410 and the muffler 420 are respectively arranged 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 catalytic converter 410. Among them, by arranging the catalytic converter 410 and the muffler 420 on both sides of the engine 110 in the height direction of the vehicle, 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 height direction of the vehicle, avoiding increasing the size of the power system 1000 due to the arrangement of the catalytic converter 410 and the muffler 420, improving the integration degree of the power system 1000, thereby reducing the volume of the power system 1000 and lowering the layout difficulty of the power system 1000.

[0144] Meanwhile, by arranging the muffler 420 to communicate with 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. When the 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 the air flows through the muffler 420, the muffler 420 is used to reduce the noise of the air flowing through it, reducing the airflow noise and improving the user experience, so as to ensure the working performance of the power system 1000.

[0145] In some embodiments, as shown in Figure 1 and Figure 4 , the exhaust assembly 400 includes a second connecting pipe 930, and the catalytic converter 410 communicates with the exhaust port of the engine 110 through the second connecting pipe 930, so that the muffler 420 can communicate with the exhaust port of the engine 110 through the catalytic converter 410, thereby ensuring that the air discharged from the engine 110 can flow through the catalytic converter 410 and the muffler 420 in sequence.

[0146] In a specific example, the second connecting pipe 930 communicates with the exhaust manifold 114 of the engine 110 (for the specific structure of the exhaust manifold 114, reference can be made to Figure 6 ), and the exhaust manifold 114 communicates with the exhaust port of the engine 110, so that the catalytic converter 410 can receive the exhaust gas of the engine 110, facilitating the purification of the exhaust gas discharged from the engine 110.

[0147] 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 discharge of air.

[0148] In some embodiments, as shown in Figure 1 , Figure 4 , Figure 5 and Figure 7 , the muffler 420 includes a first muffler 421 and a second muffler 422 that communicate with each other. The first muffler 421 communicates with the catalytic converter 410, and the second muffler 422 has an exhaust gas discharge port 4221. By arranging the muffler 420 to include the first muffler 421 and the second muffler 422 that communicate with each other, the first muffler 421 and the second muffler 422 can be used in cooperation to reduce noise, so as to increase the volume of the muffler 420, effectively reduce the airflow noise, that is, ensure the working performance of the muffler 420.

[0149] In a specific example, the air discharged from the catalytic converter 410 first flows through the first muffler 421 for noise reduction. The air after noise reduction by the first muffler 421 then enters the second muffler 422 through the third connecting pipe 430 for further noise reduction. The air after noise reduction by the second muffler 422 is discharged through the exhaust gas outlet 4221 to complete the exhaust of the engine 110.

[0150] In some embodiments, as shown in combination with Figure 1 and Figure 4 , the first muffler 421 and the second muffler 422 are spaced apart on both sides of the motor module 200 in the vehicle length direction. This fully utilizes the space of the power system 1000 in the vehicle length direction and improves the integration degree of the power system 1000.

[0151] In some embodiments, as shown in combination with Figure 1 and Figure 4 , the first muffler 421 is disposed on the front side of the motor module 200, and the second muffler 422 is disposed on the rear side of the motor module 200. In this way, while achieving the arrangement that the first muffler 421 and the second muffler 422 are spaced apart on both sides of the motor module 200 in the vehicle length direction, it can also make the exhaust gas outlet 4221 of the second muffler 422 be close to the tailpipe of the vehicle, facilitating the discharge of exhaust gas.

[0152] In some embodiments, as shown in combination with Figure 1 and Figure 4 , the catalytic converter 410 is arranged on the top of the engine 110. 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 vehicle length direction, the first muffler 421 and the second muffler 422 are close to the bottom of the engine 110. By arranging the catalytic converter 410 on the top of the engine 110, in the vehicle height direction, the catalytic converter 410 and the muffler 420 are respectively arranged on both sides of the engine 110, achieving the full utilization of the space on both sides of the engine 110 in the up and down directions, improving the integration degree of the power system 1000, thereby reducing the volume of the power system 1000 and reducing the layout difficulty of the power system 1000.

[0153] In some embodiments, as shown in combination with Figure 4 , Figure 5 and Figure 7 , a third connecting pipe 430 is provided between the first muffler 421 and the second muffler 422. The third connecting pipe 430 respectively communicates with the first muffler 421 and the second muffler 422, thereby realizing the mutual communication between the first muffler 421 and the second muffler 422 to improve the noise reduction effect of the muffler 420.

[0154] In some embodiments, as shown in combination with Figure 4 ,Figure 5 and Figure 7 As shown, the third connecting pipes 430 include two, and the two third connecting pipes 430 are spaced on both sides of the motor module 200 in the width direction of the vehicle. While realizing the communication between the first muffler 421 and the second muffler 422, the space of the power system 1000 in the width direction of the vehicle can be fully utilized to improve the integration degree of the power system 1000.

[0155] In some embodiments, in combination with Figure 1 and Figure 7 As shown, the power system 1000 further includes a turbocharger 600. The turbocharger 600 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. To improve the intake and exhaust performance of the power system 1000 and improve the working performance of the power system 1000 to a certain extent.

[0156] In some embodiments, in combination with Figure 1 and Figure 4 As shown, in the height direction of the vehicle, both the compressor 610 and the turbine 620 are arranged on the side of the engine 110 away from the motor module 200. While realizing the arrangement of the compressor 610 and the turbine 620 on the outer periphery of the engine 110, the compressor 610 can be arranged close to the air filter 310 and the intercooler 320, and the turbine 620 can be arranged close to the catalytic converter 410 and the muffler 420, so as to facilitate the realization of the communication between the compressor 610 and the air filter 310 and the intercooler 320 respectively, and the realization of the communication between the turbine 620 and the catalytic converter 410 and the muffler 420 respectively. While improving the integration degree of the power system 1000, the connection difficulty of each component in the power system 1000 can be reduced, thereby reducing the assembly difficulty of the power system 1000.

[0157] In some embodiments, the compressor 610 is respectively connected to the air filter 310 and the intercooler 320, and the turbine 620 is respectively connected to the catalytic converter 410 and the muffler 420. Among them, by respectively connecting the compressor 610 to the air filter 310 and the intercooler 320, 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, so as to increase the air pressure in the engine 110 and ensure the thermal efficiency of the engine 110, that is, to ensure the working performance of the engine 110.

[0158] At the same time, by respectively connecting the turbine 620 to the catalytic converter 410 and the muffler 420, it can be ensured that the air flowing to 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, thus realizing the efficient utilization of energy.

[0159] In some embodiments, as Figure 1 shown, the compressor 610 is arranged close to the intercooler 320. This facilitates the connection between the compressor 610 and the intercooler 320 and reduces the difficulty of connecting the compressor 610 and the intercooler 320.

[0160] Of course, in some other embodiments, the compressor 610 may also be arranged close to the air filter 310 to reduce the difficulty of connecting the compressor 610 and the intercooler 320.

[0161] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 3 shown, the turbocharger 600 further includes a fourth connecting pipe 312 and a fifth connecting pipe (not shown in the figure). 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 along the fourth connecting pipe 312 to the compressor 610. The compressor 610 is used to pressurize the filtered air. After pressurization, the air enters the intercooler 320 through the fifth connecting pipe. After the air is cooled by the intercooler 320, it 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.

[0162] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 3 shown, the 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. It can also be understood here that the fourth connecting pipe 312 extends adaptively along the shape of the first motor 120. In this way, while rationally utilizing the space between the first motor 120 and the motor module 200, it is also possible to avoid increasing the distance between the first motor 120 and the motor module 200 due to the arrangement of the fourth connecting pipe 312, so as to reduce the size of the power system 1000 in the up and down direction and improve the integration degree of the power system 1000.

[0163] In a specific example, in combination with Figure 1 , Figure 2 and Figure 3As shown, the fourth connecting pipe 312 is arranged between the first motor 120 and the controller 800. While achieving the arrangement of the fourth connecting pipe 312 between the first motor 120 and the motor module 200, the fourth connecting pipe 312 can also be arranged close to the air filter 310, which is beneficial to using the fourth connecting pipe 312 to connect the air filter 310 and the inlet of the compressor 610, reducing the connection difficulty between the air filter 310 and the compressor 610.

[0164] In some embodiments, in combination with Figure 4 and Figure 5 As shown, the turbocharger 600 further includes a sixth connecting pipe 940 and a muffler inlet 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 inlet 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 of the turbine 620 enters the interior of the muffler 420 through the muffler inlet pipe 4211.

[0165] In the description of the present invention, the features defined as "first", "second", "third", "fourth", "fifth", and "sixth" may explicitly or implicitly include one or more of such features, which are used to distinguish and describe features, without order or importance.

[0166] In some embodiments, in combination with Figure 4 and Figure 5 As shown, the muffler inlet pipe 4211 is connected to the first muffler 421. In this way, the air of the turbine 620 can enter the interior of the first muffler 421 through the muffler inlet pipe 4211. The air entering the interior of the first muffler 421 can enter the interior of the second muffler 422 through the left and right third connecting pipes 430, and finally be discharged into the atmosphere through the exhaust gas outlet 4221 of the second muffler 422 to complete the exhaust of the engine 110.

[0167] In some embodiments, the sixth connecting pipe 940 and the turbine 620 are connected by a flange to ensure the connection strength between the sixth connecting pipe 940 and the turbine 620, thereby realizing the connection between the catalytic converter 410 and the turbine 620 and facilitating the discharge of air.

[0172] It should be noted that the connection between the turbine 620 and the compressor 610 mentioned here means that the rotating shafts of the turbine 620 and the compressor 610 are connected to each other, so as to facilitate using the turbine 620 to drive the compressor 610 to rotate, thereby facilitating using the turbine 620 to increase the rotational speed of the compressor 610, which is beneficial to improving the intake performance of the intake assembly 300 and ensuring the working performance of the power system 1000 to a certain extent.

[0173] In some embodiments, in combination with Figure 1 , Figure 4 and Figure 7 As shown, the compressor 610 is arranged close to the rear end of the engine 110, so that the compressor 610 can be arranged close to the air filter 310 and the intercooler 320, thereby facilitating the connection between the compressor 610 and the air filter 310 and the intercooler 320 respectively and reducing the intake difficulty of the intake assembly 300.

[0174] Optionally, in combination with Figure 1 , Figure 4 and Figure 7As shown, the turbine 620 is disposed near the front end of the engine 110. In this way, while ensuring that the turbine 620 and the compressor 610 can be spaced apart in the longitudinal direction of the vehicle, the turbine 620 can be disposed close to the catalytic converter 410, so that the catalytic converter 410 can communicate with the turbine 620. While reducing the difficulty of connecting the turbine 620 and the catalytic converter 410, the intake and exhaust of the engine 110 can be made smoother, and the difficulty of intake and exhaust can be reduced.

[0175] With the above arrangement, in a specific example, in combination with Figures 1 - 7 As shown, the first motor 120 is fixedly connected to the engine 110 and the first motor 120 is disposed at the rear end of the engine 110 and near the middle position.

The intercooler 320 and the air filter 310 are respectively disposed on the left and right sides of the first motor 120. The controller 800 is disposed in the cavity between the first motor 120 and the motor module 200, and is integrally arranged in a conformal manner using the cavities of the first motor 120 and the motor module 200. The catalytic converter 410 is disposed on the top of the first motor 120 and near the engine 110.

The first muffler 421 and the second muffler 422 are spaced apart on both sides of the motor module 200 in the longitudinal direction of the vehicle.

[0176] In summary, the present application proposes a drive assembly integrating the engine 110, the first motor 120, the motor module 200 and the controller 800.
