In this way, the powertrain is flexibly arranged in the front cabin of the vehicle along the first direction X. At the same time, the positions of the engine 1 and the motor assembly 80 are staggered, which also facilitates the installation of other components on the engine 1, thereby improving the integration of the powertrain and reducing the space in the front cabin of the vehicle that the powertrain as a whole needs to occupy.

[0056] In an embodiment of the present application, by installing the high-voltage distribution box 4 on the engine 1, the space above the engine 1 can be reasonably utilized to improve the utilization rate of the space; at the same time, the engine 1 and the high-voltage distribution box 4 are installed together to form a module, thereby improving the integration of the engine 1 for easy assembly.

[0057] Specifically, the power assembly may further include a high-voltage distribution box bracket 5 and a distribution box wire 6. Along the first direction X, the high-voltage distribution box bracket 5 is installed on the left side of the engine 1, and the high-voltage distribution box 4 is installed on the engine 1 through the high-voltage distribution box bracket 5. One end of the high-voltage distribution box 4 is electrically connected to the motor controller 3 through the distribution box wire 6 for distributing electrical energy to the motor controller 3.

The intake pipe is at least partially arranged on the engine 1, and the intake pipe is connected to the intake end of the engine 1; the intercooler 9 is installed on the engine 1 and is connected to the intake pipe for cooling the gas in the intake pipe.

[0059] In the embodiment of the present application, part of the intake pipe is arranged on the engine 1, and the intercooler 9 is installed on the engine 1. In this way, the space on the side of the engine 1 can be reasonably utilized to improve the utilization rate of the space; at the same time, the engine 1 and the intercooler 9 are installed together to form a module, which improves the integration of the engine 1 and facilitates assembly. In addition, the intercooler 9 is integrated on the engine 1, which can reduce the length of part of the intake pipe route, thereby reducing the space occupied by the intake pipe.

In this way, the intake manifold 7, the intake hose 8, the intercooler 9, the intercooler intake pipe 10, and the intercooler outlet pipe 11 form an intake system, which cooperates with the supercharger to cool the high-temperature gas compressed by the supercharger so that the engine 1 can output higher power.

[0061] Furthermore, the air intake end of the air filter 20 is in communication with the air intake duct 19 , so that air can enter the air filter 20 through the air intake duct 19 .

[0062] It should be noted that the intercooler 9 may be a water-cooled intercooler or other types of intercoolers, and the present application does not impose any limitation thereto.

[0064] In the embodiment of the present application, by installing the catalyst 13 on the engine 1 and connecting it to the exhaust pipe, the space on the side of the engine 1 can be reasonably used to improve the utilization rate of the space; at the same time, the engine 1 and the catalyst 13 are installed together to form a module, which improves the integration of the engine 1 and facilitates assembly. In addition, integrating the catalyst 13 on the engine 1 can reduce the length of the exhaust pipe route, thereby reducing the space occupied by the exhaust pipe.

[0065] Specifically, along the first direction X, the catalyst 13 is installed on the right side of the engine 1, and the exhaust pipeline at least includes a connecting pipe (not shown in the figure), a catalyst 13 and an exhaust pipe 12. The air inlet end of the connecting pipe is connected to the exhaust end of the engine, and the air outlet end of the connecting pipe is connected to the air inlet end of the catalyst 13.

In this way, the exhaust gas of the engine 1 is purified by the catalyst 13 and discharged from the exhaust pipe 12.

[0066] Alternatively, if Figures 1 to 3 As shown, the powertrain further includes an air-conditioning compressor 14 , which is mounted on the engine 1 and is used to be connected to the vehicle air-conditioning.

[0067] In the embodiment of the present application, by installing the air-conditioning compressor 14 on the engine 1, the space on the side of the engine 1 can be reasonably utilized to improve the utilization rate of the space; at the same time, the engine 1 and the air-conditioning compressor 14 are installed together to form a module, which improves the integration of the engine 1 for easy assembly.

[0070] In the embodiment of the present application, by installing both the low-temperature water pump 15 and the high-temperature water pump 16 on the engine 1 and connecting them to the cooling system, the space at the bottom of the engine 1 can be reasonably utilized to improve the utilization rate of the space; at the same time, the engine 1 and the low-temperature water pump 15 and the high-temperature water pump 16 are installed together to form a module, which improves the integration of the engine 1 and facilitates assembly. In addition, the low-temperature water pump 15 is integrated on the engine 1, and the low-temperature water pump 15 can pump cooling water into the cooling system in the engine to cool the engine 1.

[0071] Specifically, the low-temperature water pump 15 and the high-temperature water pump 16 are installed at the bottom of the engine 1, the low-temperature water pump 15 is connected to the low-temperature water tank 34, and the high-temperature water pump 16 is connected to the high-temperature water tank 35. Cooling water flows out of the low-temperature water tank 34 and is pumped into the cooling system of the engine 1 through the low-temperature water pump 15 to cool the engine 1, so as to facilitate cooling of the engine.

[0072] Alternatively, if Figures 1 to 5 As shown, the powertrain also includes an engine suspension 81, one end of which is connected to the engine 1 along the first direction X, and the other end is suitable for connecting to the frame 45 of the vehicle; and / or, it also includes a motor suspension 82, one end of which is connected to the motor assembly 80 along the first direction X, and the other end is suitable for connecting to the frame 45 of the vehicle.

[0073] In the embodiment of the present application, one end of the engine suspension 81 is connected to the engine 1 along the first direction X, and one end of the motor suspension 82 is connected to the motor assembly 80 along the first direction X. In this way, the torsional reaction force can be overcome when the car moves in the first direction X, so that the powertrain can be stably installed in the front cabin of the car, thereby improving the stability of the car.

[0074] In some embodiments, the suspension is subjected to the greatest force in the first direction X when the vehicle is moving forward and backward, especially for off-road vehicles. Considering their complex working conditions, such as the worst Belgian road section (the test section paved with irregular, uneven, and different-sized stones is called the Belgian road), the force on the suspension in the first direction X will increase by 3 to 5 times. In the braking condition, in order to prevent the suspension bolts in the powertrain from loosening and causing abnormal loads on the engine 1 and the motor 2, a special suspension tightening direction needs to be set to stabilize the engine 1 and the motor 2.

[0075] like Figures 4 to 5As shown, the engine mount 81 includes a first mount 21, a second mount 22, a first fastener 58 and a second fastener 59. The first mount 21 and the second mount 22 are connected to the engine 1 along the first direction X, the first fastener 58 sequentially penetrates the first mount 21 and the engine 1 along the direction from the front of the vehicle to the rear of the vehicle, and the second fastener 59 sequentially penetrates the second mount 22 and the engine 1 along the direction from the rear of the vehicle to the front of the vehicle, so that the penetration directions of the first fastener 58 and the second fastener 59 are opposite to each other, so as to overcome the torsional reaction force. Of course, the penetration directions of the first fastener 58 and the second fastener 59 can be exchanged, and the embodiment of the present application will not be repeated here.

[0076] In some embodiments, the motor mount 82 includes a third mount 23 and a fourth mount 24. Similar to the principle of installing the first mount 21 and the second mount 22 on the engine 1, the fasteners in the third mount 23 and the fasteners in the fourth mount 24 can be installed in opposite directions.

[0077] Furthermore, the fasteners in the first suspension 21 and the fasteners in the second suspension 22 may be arranged in opposite or same directions; the fasteners in the third suspension 23 and the fasteners in the fourth suspension 24 may be arranged in opposite or same directions;

[0078] It should be noted that the suspension can be a semi-active suspension, and the high-frequency vibration isolation capability of the semi-active suspension is equivalent to that of the hydraulic suspension, which can provide the driver with a more comfortable driving experience. Of course, the suspension can also adopt other types of suspension, which is not limited in this application.

[0079] Alternatively, if Figure 6-Figure 8 As shown, the present application also provides a vehicle front cabin structure, including a front cabin body and any of the powertrains described above; a receiving chamber 27 is formed in the front cabin body, the engine 1 is disposed in the receiving chamber 27, and the motor assembly 80 at least partially extends outside the receiving chamber 27.

[0080] In an embodiment of the present application, the engine 1 is disposed in the accommodating cavity 27 in the front cabin body, and the motor assembly 80 is at least partially extended outside the accommodating cavity 27. In this way, the power assembly can be flexibly arranged in the front cabin of the vehicle along the first direction X. At the same time, the positions of the engine 1 and the motor assembly 80 are staggered, which also facilitates the installation of other components on the engine 1, thereby improving the integration of the power assembly and reducing the space in the front cabin of the vehicle that the power assembly as a whole needs to occupy. Thus, installation space can be reserved for other front cabin accessories, so as to facilitate the reasonable installation layout of various components in the front cabin structure.

[0081] Alternatively, if Figure 6-Figure 8As shown, the front cabin body includes a front cabin sheet metal 25 and a front panel 26. The front cabin sheet metal 25 and the front panel 26 enclose a receiving cavity 27. The front panel 26 is arranged above the motor assembly 80. Along the first direction X, there is an avoidance space between the engine and the front panel.

[0082] In an embodiment of the present application, the front cabin sheet metal 25 is a semi-closed structure, and the front panel 26 is connected to the opening part of the front cabin sheet metal 25 to form a accommodating cavity 27. By arranging the front panel 26 above the motor assembly 80 and there is a gap between the engine 1 and the front panel 26, the engine 1 is farther away from the front panel 26, leaving a deformation buffer space for a frontal collision, thereby improving the safety of the vehicle.

[0083] Specifically, Fig.13 As shown, the motor 2 and the motor controller 3 are arranged below the central tunnel 57 and are offset from the front wall 26 in the vehicle height direction.

[0084] Alternatively, if Figure 6-Figure 8 As shown, the front cabin sheet metal 25 includes a first longitudinal beam 251, a second longitudinal beam 252 and a first cross beam 253. The first longitudinal beam 251 and the second longitudinal beam 252 are respectively connected to the front panel 26.
