The engine 1 is at least partially staggered with the motor assembly 80 along the first direction X in the orthographic projection. The engine 1 and / or the motor assembly 80 are configured to output power to a transmission shaft of a vehicle.

[0048] In the embodiments of the present application, the engine 1 is arranged on one side of the motor assembly 80 structure along the first direction X, and the engine 1 is at least partially staggered with the motor assembly 80 along the first direction X. In this way, the power assembly 100 is facilitated to be flexibly arranged in the vehicle front compartment along the first direction X.

[0059] Specifically, the power assembly 100 can further include a high-voltage distribution box support 5 and a distribution box wire 6. Along the first direction X, the high-voltage distribution box support 5 is installed on the left side of the engine 1.

One end of the high-voltage distribution box 4 is electrically connected to the motor controller 3 through the distribution box wire 6, and is used to distribute electric energy for the motor controller 3.

[0060] Optionally, as shown in FIGS. 1-3, the power assembly 100 further includes an intake pipe and an intercooler 9. The intake pipe is at least partially arranged on the engine 1.

[0061] In the embodiment of the present application, by arranging the partial intake pipeline on the engine 1, the intercooler 9 is installed on the engine 1, so that the space on the side of the engine 1 can be reasonably utilized, and the space utilization is improved. Meanwhile, the engine 1 and the intercooler 9 are installed together to form a module, and the integration of the engine 1 is improved to facilitate assembly. Moreover, the integration of the intercooler 9 on the engine 1 can reduce the length of the partial intake pipeline, and further reduce the space occupied by the intake pipeline.

[0063] Further, the intake end of the air filter 20 is in communication with the intake flow guide pipe 19, so that air enters the air filter 20 through the intake flow guide pipe 19.

[0064] It should be noted that the intercooler 9 can be a water-cooled intercooler, or other types of intercooler, which is not limited in the present application.

[0066] In the embodiment of the present application, by installing the catalytic converter 13 on the engine 1 and in communication with the exhaust pipeline, the space on the side of the engine 1 can be reasonably utilized, and the space utilization is improved. Meanwhile, the engine 1 and the catalytic converter 13 are installed together to form a module, and the integration of the engine 1 is improved to facilitate assembly.

[0068] Optionally, as shown in FIGS. 1-3, the power assembly 100 further comprises an air conditioner compressor 14. The air conditioner compressor 14 is installed on the engine 1 and is used to be connected with the vehicle air conditioner.

[0069] In the embodiment of the present application, by installing the air conditioner compressor 14 on the engine 1, the space on the side of the engine 1 can be reasonably utilized, and the utilization rate of the space is improved. Meanwhile, the engine 1 and the air conditioner compressor 14 are installed together to form a module, and the integration degree of the engine 1 is improved to facilitate assembly.

[0075] In the embodiment of the present application, one end of the engine suspension 81 is connected with the engine 1 along the first direction X, and one end of the motor suspension 82 is connected with the motor assembly 80 along the first direction X. In this way, the power assembly 100 is stably installed in the front compartment of the vehicle to improve the stability of the vehicle by overcoming the torsional reaction force when the vehicle moves in the first direction X.

[0076] In some embodiments, the suspension is subjected to the maximum force in the first direction X when the vehicle moves forward and backward, especially for off-road vehicles, considering the complex working conditions, such as the worst Belgian section (a test section paved with irregular, uneven, and various sizes of stones, which is called Belgian road), the force on the suspension in the first direction X can be increased by 3 to 5 times. In the braking working condition, in order to prevent the suspension bolts in the power assembly 100 from loosening and causing the engine 1 and the motor 2 to be abnormally loaded, therefore, a special suspension fastening direction is needed to be set to make the engine 1 and the motor 2 stable.

[0077] As shown in FIG. 4 to FIG. 5, the engine suspension 81 comprises a first suspension 21, a second suspension 22, a first fastener 58, and a second fastener 59. The first suspension 21 and the second suspension 22 are connected with the engine 1 along the first direction X, the first fastener 58 is sequentially arranged in the first suspension 21 and the engine 1 in the direction from the front to the rear, and the second fastener 59 is sequentially arranged in the second suspension 22 and the engine 1 in the direction from the rear to the front. In this way, the arrangement directions of the first fastener 58 and the second fastener 59 are opposite to each other to overcome the torsional reaction force. Of course, the arrangement directions of the first fastener 58 and the second fastener 59 can be exchanged, which is not described herein in the embodiment of the present application.

[0078] In some embodiments, the motor suspension 82 comprises a third suspension 23 and a fourth suspension 24. Similar to the first suspension 21 and the second suspension 22 installed on the engine 1, the arrangement directions of the fasteners in the third suspension 23 and the fourth suspension 24 are opposite to each other.

[0079] Further, the arrangement directions of the fasteners in the first suspension 21 and the second suspension 22 can be opposite or the same, and the arrangement directions of the fasteners in the third suspension 23 and the fourth suspension 24 can be opposite or the same.

[0080] It should be noted that the suspension can be a semi-active suspension, and the high-frequency part of the semi-active suspension has a vibration isolation capability equivalent to that of a hydraulic suspension, which can provide a more comfortable driving experience for the driver. Of course, the suspension can also use other types of suspensions, which are not limited in the present application.

[0081] Optionally, as shown in FIGS. 6-8 and FIG. 14, the present application also provides a vehicle front compartment structure 1000, comprising a front compartment body 200 and the power assembly 100 of any one of the above. The front compartment body 200 is formed with a receiving cavity 27. The engine 1 is arranged in the receiving cavity 27. The motor assembly 80 at least partially extends out of the receiving cavity 27.

[0082] In the embodiments of the present application, by arranging the engine 1 in the receiving cavity 27 in the front compartment body 200 and making the motor assembly 80 at least partially extend out of the receiving cavity 27, it is convenient to flexibly arrange the power assembly 100 in the vehicle front compartment along the first direction X. At the same time, by arranging the engine 1 and the motor assembly 80 in a staggered manner, it is also convenient to install other components on the engine 1, thereby improving the integration of the power assembly 100, reducing the space occupied by the power assembly 100 in the vehicle front compartment, and further being able to leave installation space for other front compartment accessories, so as to facilitate the reasonable installation and arrangement of each component in the front compartment structure.

[0083] Optionally, as shown in FIGS. 6-8, the front compartment body 200 comprises a front compartment panel 25 and a front wall 26. The front compartment panel 25 and the front wall 26 form the receiving cavity 27. The front wall 26 is arranged above the motor assembly 80. There is a clearance between the engine and the front wall along the first direction X.
