[0026] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-8 A vehicle 100 according to an embodiment of the present invention is described.
[0027] like Figure 1-Figure 3 As shown, a vehicle 100 according to an embodiment of the present invention includes an engine 10, a generator assembly 20, and a drive motor assembly 30. Specifically, the generator assembly 20 is disposed on one side of the engine 10 in a first direction, and the drive motor assembly 30 is disposed on one side of the engine 10 in a second direction; wherein the first direction is perpendicular to the second direction.
[0028] For example, in Figure 3 In the example, the powertrain includes an engine 10, a generator assembly 20, and a drive motor assembly 30, and the first direction is the driving direction of the vehicle 100 (for example, Figure 3 The second direction is the height direction of the vehicle 100 (for example, Figure 3 up and down directions in the .
[0029] According to the vehicle 100 of the embodiment of the present invention, by arranging the generator assembly 20 on one side of the engine 10 in the first direction and arranging the drive motor assembly 30 on one side of the engine 10 in the second direction, the angle of the transmission shaft can be satisfied to be ≤3°, and no movement space needs to be reserved between the generator assembly 20 and the drive motor assembly 30. Compared with the powertrain with a split arrangement in the prior art, such an arrangement makes the powertrain of the vehicle 100 more compact, improves the space utilization of the entire vehicle, thereby improving the versatility of the powertrain, and can be installed in a sedan or a vehicle with a small front cabin space.
[0030] In specific implementation, the gap between the generator assembly 20 and the drive motor assembly 30 is 5 mm, which saves 23.6% of the space compared with the movement space reserved between the generator assembly 20 and the drive motor assembly 30 in the prior art. The length dimension of the powertrain is reduced from 960 mm to 733 mm, which occupies less space and has a more compact layout. It can also meet the cabin layout and pedestrian protection requirements of the vehicle 100 (i.e., the gap from the powertrain to the outer panel of the cabin cover must be greater than 80 mm).
[0031] According to some embodiments of the present invention, the generator assembly 20 includes a generator 21 and a first controller 22, the first controller 22 is connected to the generator 21, and the generator 21 and the first controller 22 are arranged side by side along a third direction, which is the width direction of the vehicle 100 (for example, Figure 1 left and right directions in the .
[0032] It should be noted that the present application eliminates the speed-increasing gear set in the prior art, and the width dimension of the engine 10 is reduced by about 140 mm.
[0033] By arranging the generator 21 and the generator controller 21 side by side along the third direction, the space in the cabin in that direction can be fully utilized, making the layout of the entire powertrain more compact. This also facilitates the positioning and connection of the generator 21 and the first controller 22, eliminating the need for installation and maintenance within complex angles and spatial constraints. Furthermore, the generator 21 and the first controller 22 are connected and arranged side by side, shortening the electrical connection between the generator 21 and the first controller 22, thereby reducing power loss during transmission.
[0034] According to some embodiments of the present invention, Figure 3 and Figure 7 As shown, the drive motor assembly 30 includes a housing 31 , a first drive motor 32 , a second drive motor 33 and a second controller 34 .
[0035] Specifically, the first drive motor 32 is disposed within the housing 31, and the second drive motor 33 is disposed within the housing 31. The second drive motor 33 and the first drive motor 32 are arranged along the third direction. The second controller 34 is disposed within the housing 31, and the second controller 34 is connected to the first drive motor 32 and the second drive motor 33, respectively. In the second direction, the second controller 34 is located below the first drive motor 32 and the second drive motor 33.
[0036] By arranging the first drive motor 32 and the second drive motor 33 along the third direction and positioning the second controller 34 below the first and second drive motors 32 and 33 in the second direction, the space requirement of the controller and the two drive motors, as in the prior art, is avoided. This fully utilizes the space within the housing 31, making the drive motor assembly 30 more compact and facilitating efficient powertrain integration. Furthermore, this arrangement helps lower the powertrain's center of gravity, thereby improving the vehicle 100's driving stability.
[0037] Specifically, the drive motor assembly 30 further includes a plurality of protective plates 35, which are respectively provided on both sides of the housing 31 in the third direction. In the description of the present invention, "plurality" means two or more.
[0038] For example, in Figure 7 In the example shown, two protective plates 35 are provided, one on each side of the first drive motor 32 and the other on the second drive motor 33. The second controller 34 is located between the two protective plates 35 to prevent the second controller 34 from being squeezed by other components of the vehicle 100 and posing a high-voltage safety risk. In practice, the protective plates 35 are made of 5 mm thick steel plates to increase the protective area of the second controller 34 and prevent it from being squeezed.
[0039] In some optional embodiments, such as Figure 6 As shown, the engine 10 includes a cylinder block 19, an oil sump, and an oil reservoir 11. Specifically, the oil sump (not shown) is located between the cylinder block 19 and the drive motor assembly 30. The oil reservoir 11 is located on the side of the cylinder block away from the generator assembly 20. The oil reservoir 11 and the first controller 22 are both located on the same side in the third direction.
[0040] With this arrangement, the oil reservoir 11 and the first controller 22 are located on the same side of the third direction, with the oil reservoir 11 on the side of the cylinder block 19 away from the drive motor assembly 30. This arrangement optimizes the spatial distribution of the various components of the engine 10. This improves the compactness of the engine 10 and increases space utilization within the engine compartment. Furthermore, the placement of the oil pan between the cylinder block 19 and the drive motor assembly 30 provides a sound foundation for the engine 10's lubrication system. The oil pan collects and stores lubricating oil, ensuring a stable supply of lubricating oil to all components requiring lubrication during engine 10 operation. Furthermore, the oil pan's location creates a heat transfer buffer between the engine 10 and the drive motor assembly 30, preventing excessive heat from the engine 10 from being directly transferred to the drive motor assembly 30. This prevents overheating and potentially damaging the first and second drive motors 32 and 33, helping to maintain a temperature balance between the engine 10 and the drive motor assembly 30.
[0041] In the specific implementation, the oil pan adopts a dry oil pan with a depth of 80mm. The capacity of the oil reservoir 11 is 6.5L. The oil reservoir 11 draws oil through the internal oil pump of the oil pan to ensure that the oil will not be sucked out when the maximum front and rear tilt angle of the vehicle is 45° and the left and right tilt angle is 42°.
[0042] Furthermore, an oil pump (not shown) is installed within the oil pan, and an oil retaining structure (not shown) is provided above the oil reservoir 11 in the second direction. This prevents oil from splashing from the oil reservoir 11 onto other components and causing a fire in the event of a collision. Furthermore, there is no oil dipstick on the oil reservoir 11. Instead, the ECU (Electronic Control Unit) reads the parameters of an oil pressure sensor located above the engine 10 in the second direction to determine the oil level.
[0043] According to some embodiments of the present invention, engine 10 includes an intake manifold 12, an exhaust manifold (not shown), an intercooler 13, and a throttle valve 14. Intake manifold 12 is disposed below cylinder block 19 in a second direction, while exhaust manifold 13 is disposed above cylinder block 19 in the second direction. Intercooler 13 is in communication with intake manifold 12 and is located below intake manifold 12. Throttle valve 14 is disposed on intercooler 13 and in communication with intake manifold 12.
[0044] Positioning the intake manifold 12 below the cylinder block 19 in the second direction and the exhaust manifold above the cylinder block 19 in the second direction takes advantage of the rising nature of hot air. Since the exhaust gas from combustion in the engine 10 is at a relatively high temperature, this arrangement allows the exhaust gas to exit the cylinder block 19 more quickly, preventing the heat radiation from the high-temperature exhaust gas from affecting the drive motor assembly 30. Furthermore, since the intercooler 13 is positioned below the intake manifold 12 in the second direction, air first passes through the intercooler 13 before entering the intake manifold 12 during the intake process. This allows the intercooler 13 to provide better cooling, mitigating the risk of water accumulation and ice formation in the intake manifold 12 in cold weather. Furthermore, the throttle 14, located on the intercooler 13 and connected to the intake manifold 12, ensures precise control of air intake. The throttle 14 can adjust the intake air volume based on the operating conditions of the engine 10. Working in conjunction with the intercooler 13, both the volume and temperature of air entering the intake manifold 12 can be precisely regulated. When the engine 10 runs at a low speed, the throttle valve 14 can appropriately reduce the intake air volume, while the intercooler 13 can still cool the intake air, maintain a stable intake state, and improve the fuel economy of the engine 10.
[0045] In a specific implementation, the minimum distance H4 between the intercooler 13 and the intake manifold 12 in the second direction satisfies: 30 mm ≤ H4 ≤ 60 mm.
[0046] When H4 is less than 60 mm, the minimum distance between the intercooler 13 and the intake manifold 12 is too small, potentially affecting the intake air flow space, reducing the intake efficiency of the engine 10, and increasing the difficulty of maintenance. When H4 is greater than 60 mm, the risk of water accumulation and freezing in the intake manifold 12 in cold weather cannot be avoided, and the space occupancy rate increases, hindering the compact design of the vehicle 100. Therefore, by setting the minimum distance H4 between the intercooler 13 and the intake manifold 12 in the second direction within the range of 30 mm ≤ H4 ≤ 60 mm, the intake efficiency of the engine 10 is guaranteed while avoiding the risk of water accumulation and freezing in the intake manifold 12 in cold weather.
[0047] Specifically, the outer peripheral surface of the exhaust manifold is wrapped with a heat insulating member 17; and / or the outer peripheral side of the exhaust manifold is provided with a heat insulating baffle 18, and in the second direction, the end of the heat insulating baffle 18 away from the cylinder block 19 is lower than the end of the exhaust manifold away from the cylinder block 19.
[0048] For example, in Figure 6 In the example shown in FIG, the outer circumference of the exhaust manifold is wrapped with a heat insulating member 17, and the outer circumference of the exhaust manifold is provided with a heat insulating baffle 18. Of course, only the outer circumference of the exhaust manifold may be wrapped with the heat insulating member 17, or only the outer circumference of the exhaust manifold may be provided with a heat insulating baffle 18.
[0049] This arrangement avoids heat radiation to the cylinder block 19 caused by the exhaust manifold being positioned above the cylinder block 19 in the second direction, and protects heat-sensitive components such as sensors, piping, and wiring harnesses within the engine 10. In practice, the heat shield 18 is positioned 10 mm below the exhaust manifold in the second direction to ensure that the hot air flow is discharged from the vehicle 100 along the flow field of the engine compartment.
[0050] It should be noted that the thermal insulation member 17 may be made of thermal insulation cotton with a thickness of about 8 mm, and this application does not make any specific limitation on this.
[0051] According to some embodiments of the present invention, the minimum distance between the end of the heat insulation baffle 18 away from the cylinder body 19 and the end of the exhaust manifold away from the cylinder body 19 in the second direction is H1, where H1 satisfies: H1 ≥ 10 mm.
[0052] When H1 is less than 10 mm, the minimum distance between the end of the heat shield 18 away from the cylinder block 19 and the end of the exhaust manifold away from the cylinder block 19 is too small, and the heat shield 18 cannot effectively isolate the high-temperature exhaust gas from the surrounding environment. A high-temperature environment will form in a localized area, thereby affecting the normal operation of other heat-sensitive components, increasing the risk of engine 10 failure, and hindering the hot air flow from the vehicle 100 along the engine compartment flow field. Therefore, setting the minimum distance H1 between the end of the heat shield 18 away from the cylinder block 19 and the end of the exhaust manifold away from the cylinder block 19 within the range of H1 ≥ 10 mm can ensure the normal operation of the engine 10 and facilitate the hot air flow from the vehicle 100 along the engine compartment flow field.
[0053] Further, if Figure 4-Figure 6 As shown, engine 10 also includes an exhaust pipe 15, a catalyst (not shown), and an air filter 16. Specifically, exhaust pipe 15 is connected to cylinder block 19 and is located behind cylinder block 19 in the first direction. The catalyst is connected to exhaust pipe 15 and is located on the side of generator 21 away from first controller 22. The air filter 16 is located on the side of cylinder block 19 away from generator 21 and is connected to cylinder block 19. Both the catalyst and air filter 16 are located on one side in the third direction.
[0054] By connecting the exhaust pipe 15 to the cylinder body 19 and positioning it behind the cylinder body 19 in a first direction, the exhaust gas after combustion is discharged backward under the action of pressure, reducing exhaust resistance, allowing the exhaust gas to be discharged from the engine 10 more quickly and smoothly, and improving exhaust efficiency. The catalyst is connected to the exhaust pipe 15 and is located on the side of the generator 21 away from the first controller 22, providing good conditions for exhaust gas purification. The exhaust gas enters the catalyst directly from the exhaust pipe 15, making the catalysis of the exhaust gas more efficient. Moreover, the air filter 16 is located on the side of the cylinder body 19 away from the generator 21 and connected to the cylinder body 19, which can better cooperate with the exhaust pipe 15, ensure the quality and stability of the air entering the cylinder body 19, and help improve the combustion efficiency of the engine 10. In addition, the catalyst and air filter 16 are both located on one side of the length direction of the engine 10, making the layout of the engine 10 in the length direction more reasonable and compact.
[0055] In practice, to ensure intake resistance is ≤ 5 kPa and minimize the length of intake manifold 12, air filter 16 is positioned to the right front of engine 10. Vehicle 100 also has an IPB (Intelligent Parking Brake) system installed on the right side of the engine 10, placing the catalyst on the right side of the engine 10 to mitigate heat damage.
[0056] Furthermore, vehicle 100 also includes a fan and a motor (not shown). The fan is positioned forward of engine 10 in the first direction. The motor is electrically connected to the fan and positioned between intercooler 13 and air filter 16. In the third direction, the motor is positioned on the side of air filter 16 adjacent to first controller 22.
[0057] Positioning the fan in front of the engine 10 in the second direction directly directs cool air toward the engine 10 and surrounding components, effectively lowering the engine's operating temperature, preventing local overheating, and improving its reliability and durability. The fan also enhances the heat dissipation of the intercooler 13, ensuring adequate cooling of the high-temperature intake air after turbocharging, improving intake efficiency and engine 10 performance. Furthermore, the motor is located between the intercooler 13 and the air filter 16, fully utilizing the limited space within the engine 10 compartment. This allows for a more compact connection between the motor and fan, reducing wiring length and complexity, and lowering energy loss and the probability of failure. Furthermore, in the third direction, the motor is located on the side of the air filter 16 adjacent to the first controller 22, enhancing the integration of the powertrain. The fan and motor provide cooling and air supply for the engine 10, while the intercooler 13 and air filter 16 cool and filter the intake air, respectively, and the first controller 22 provides precise control of the entire system. This ensures that the engine 10 can maintain a good working condition under various working conditions, thereby improving power output, fuel economy and emission performance.
[0058] In some optional embodiments, the minimum distance between the intercooler 13 and the motor in the second direction is H2, where H2 satisfies: 10 mm ≤ H2 ≤ 20 mm.
[0059] When H2 is less than 10 mm, the minimum distance between the intercooler 13 and the motor is too small, which may affect the circulation of air around the motor and the heat dissipation effect of the motor, thereby affecting the normal operation of the fan; when H2 is greater than 20 mm, the minimum distance between the intercooler 13 and the motor is too large, occupying a large space in the engine compartment of the engine 10, which is not conducive to the compact design of the engine 10. Therefore, by setting the minimum distance H2 between the intercooler 13 and the motor within the range of 10 mm ≤ H2 ≤ 20 mm, it does not affect the normal operation of the fan and the motor, and is also conducive to the compact design of the engine 10, ensuring that there are no rigid parts within 170 mm behind the fan motor.
[0060] According to some embodiments of the present invention, Figure 1-Figure 4 As shown, the vehicle 100 further includes a battery pack (not shown), a refrigerant integrated module 40 and a compressor 50 .
[0061] Specifically, the refrigerant integrated module 40 is located behind the drive motor assembly 30 in the first direction and is connected to the battery pack. The compressor 50 is located in front of the refrigerant integrated module 40 in the first direction and is connected to the housing 31. In the third direction, the compressor 50 and the first controller 22 are located on either side of the generator 21.
[0062] Placing the refrigerant integrated module 40 behind the drive motor assembly 30 in the first direction can fully utilize the air flow during the driving process of the vehicle 100 to dissipate heat, thereby improving energy utilization efficiency. Moreover, the compressor 50, the refrigerant integrated module 40 and the battery pack are tightly connected, enabling good collaborative work. The compressor 50 provides power to the refrigerant integrated module 40, enabling it to circulate and flow, thereby achieving heat dissipation for the battery pack. In addition, such a setting fully utilizes the limited space on the vehicle 100, avoids mutual interference between components and waste of space, improves the space utilization rate on the vehicle 100, and makes the entire vehicle 100 more compact in space.
[0063] Specifically, the vehicle 100 further includes a subframe 60 , which is disposed below the drive motor assembly 30 in the second direction. The minimum distance between the subframe 60 and the drive motor assembly 30 in the second direction is H3 , where H3 satisfies: 15 mm ≤ H3 ≤ 20 mm.
[0064] When H3 is less than 15 mm, the minimum distance between the subframe 60 and the drive motor assembly 30 is too small, increasing the difficulty of installing and maintaining the drive motor assembly 30. When H3 is greater than 20 mm, the minimum distance between the subframe 60 and the drive motor assembly 30 is too large, and the subframe 60 cannot protect the drive motor assembly 30, which may be damaged by objects such as stones, and the space utilization is increased. Therefore, setting the minimum distance H3 between the subframe 60 and the drive motor assembly 30 within the range of 15 mm ≤ H3 ≤ 20 mm not only reduces the difficulty of installing and maintaining the drive motor assembly 30, but also prevents the drive motor assembly 30 from being damaged by objects such as stones, and makes the entire vehicle 100 more compact.
[0065] According to some embodiments of the present invention, the vehicle 100 further includes a high-temperature auxiliary water tank 61 , a low-temperature auxiliary water tank 62 , a high-temperature water pump 71 , and two low-temperature water pumps 72 .
[0066] Specifically, the high-temperature auxiliary water tank 61 and the low-temperature auxiliary water tank 62 are both located on the side of the generator 21 away from the first controller 22, with the high-temperature auxiliary water tank 61 located rearward of the low-temperature auxiliary water tank 62 in the first direction. A high-temperature water pump 71 is connected to the side of the housing 31 away from the low-temperature auxiliary water tank 62. Both low-temperature water pumps 72 are located below the engine 10 in the second direction, one on each side in the third direction, and are connected to the subframe 60.
[0067] By providing a high-temperature auxiliary water tank 61 and a low-temperature auxiliary water tank 62, with the high-temperature water pump 71 located in the circuit of the engine assembly 10 and the two low-temperature water pumps 72 located in the circuit of the drive motor assembly 30, it is possible to achieve zoned cooling of different parts of the engine 10, thereby improving cooling efficiency and ensuring that all parts of the engine 10 can operate within an appropriate temperature range. Furthermore, by arranging both the high-temperature auxiliary water tank 61 and the low-temperature auxiliary water tank 62 on the side of the generator 21 away from the first controller 22, the space in the engine compartment of the engine 10 can be fully utilized. Furthermore, the arrangement of the high-temperature auxiliary water tank 61 and the low-temperature auxiliary water tank 62 has a wider range of applications than the integrated high- and low-temperature water tank solutions in the prior art, and can be applied to vehicles 100 with smaller cabin space. Furthermore, the low-temperature water pump 72 is connected to the subframe 60, which can improve the stability and seismic performance of the water pump, thereby extending the service life of the low-temperature water pump 72.
[0068] According to some embodiments of the present invention, the vehicle 100 further includes a plurality of first suspension devices 81 and a plurality of second suspension devices 82 .
[0069] Specifically, if Figures 1-8 As shown, a plurality of first suspension devices 81 are provided on both sides in the third direction, with one end of each first suspension device 81 connected to the engine 10 and the other end of each first suspension device 81 connected to the vehicle body. A plurality of second suspension devices 82 are provided on both sides of the drive motor assembly 30 in the third direction, with one end of each second suspension device 82 connected to the drive motor assembly 30 and the other end of each second suspension device 82 connected to the subframe 60.
[0070] For example, in Figure 8 In the example, two first suspension devices 81 are provided, and four second suspension devices 82 are provided. Because the powertrain in the prior art adopts a split layout, eight suspension points are required, making the suspension solution relatively complex. Compared with the prior art, the present application eliminates two suspension installation points, making the suspension solution simpler and improving assembly efficiency. This also contributes to the lightweight design of the vehicle 100 and reduces costs.
[0071] Specifically, the generator assembly 20 and the drive motor assembly 30 are fixedly connected by multiple fixing members. In a specific implementation, the fixing members can be bolts, etc., which are not specifically limited in this application. Multiple threaded holes are formed in the generator assembly 20 and the drive motor assembly 30, and the fixing members are inserted into the threaded holes.
[0072] According to some embodiments of the present invention, the engine 10 is a horizontally opposed engine, the generator 21 is a direct-connected generator, and the drive motor assembly 30 is a U-shaped dual-motor drive assembly.
[0073] It should be noted that the cylinders of the horizontally opposed engine 10 are arranged horizontally on both sides of the crankshaft, and the structure is relatively compact, which is conducive to the compact layout of the engine 10 cabin of the vehicle 100. By setting up a direct-connected engine, it can be ensured that the energy absorption space of the entire vehicle is greater than 380mm (that is, the gap between the center point of the energy absorption box and the front panel, and the gap between rigid parts). The direct-connected engine, that is, the flywheel of the engine 10 is directly connected to the input shaft of the generator 21. The speed of the generator 21 is equal to the speed of the engine 10, which reduces energy loss, improves power generation efficiency, and better adapts to the power demand of the vehicle 100 under different working conditions. The U-shaped dual-motor drive assembly is a first drive motor 32, a first controller 22 and a second drive motor 33 arranged in a U shape (such as Figure 7 As shown in the figure, the integration of the entire powertrain is improved.
[0074] Other components and operations of the vehicle 100 according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.
