[0033] In the following description, reference will be made to Figures 1 to 4 The specific structure of the above components of the four-motor pure electric platform configuration and the connection relationship of the above components are specifically described.

[0034] like Figures 1 to 4 As shown, in an embodiment, the front motor suspension 1 can be mounted on the front subframe 10 of the vehicle (in an embodiment, the front is close to the front direction and the rear is close to the rear direction). The front dual motor 2 can be mounted on the front motor suspension 1. Preferably, the front dual motor 2 can be arranged in a forward rotation, so that the space of the passenger compartment in the length direction of the vehicle can be increased. The rear motor suspension 3 can be mounted on the rear subframe 30 of the vehicle. The rear dual motor 4 can be mounted on the rear motor suspension 3. Preferably, the rear dual motor 4 can be arranged in a backward rotation, so that the size of the rear dual motor 4 in the height direction of the vehicle can be reduced to increase the volume of the luggage compartment. The high-voltage system 5 can be integrated in the floor spare tire compartment groove 50 to avoid encroaching on the front trunk space. The thermal management system can be integrated on the side of the front dual motor 2 to increase the volume of the front trunk. Such an arrangement can effectively improve the space utilization of pure electric vehicles, thereby meeting the needs of users.

[0035] Preferably, Figure 1 and Figure 2As shown, in the embodiment, the front dual motor 2 can be arranged in a forward rotation, that is, the front dual motor 2 is arranged in front of the differential. In addition, the front dual motor 2 can be arranged in a Z-shaped configuration, that is, Figure 2 As shown, the first inverter 20 can be arranged on the top of the front dual motor 2. Such an arrangement can not only meet the layout space requirements of the steering system, but also reduce the platform L113 value (the distance from the front wheel center to the driver's footrest), increase the size of the passenger compartment in the length direction of the vehicle, reduce the encroachment on the front trunk, and thus improve the vehicle space utilization.

[0036] Preferably, Figure 1 and Figure 2 As shown, in an embodiment, the front dual motor 2 can be connected to the front subframe 10 through the front motor suspension 1. The front motor suspension 1 may include a front motor left front suspension 11, a front motor right front suspension 12, a front motor left rear suspension 13, and a front motor right rear suspension 14. Among them, the front motor left front suspension 11 can be arranged at the left front of the lower part of the front dual motor 2. The front motor left front suspension 11 can be installed on the front subframe 10 by bolts. The front motor right front suspension 12 can be arranged at the right front of the lower part of the front dual motor 2. The front motor right front suspension 12 can be installed on the front subframe 10 by bolts. The front motor left rear suspension 13 can be arranged at the left rear of the lower part of the front dual motor 2. The front motor left rear suspension 13 can be installed on the front subframe 10 by bolts. The front motor right rear suspension 14 can be arranged at the right rear of the lower part of the front dual motor 2. The front motor right rear suspension 14 can be installed on the front subframe 10 by bolts. In addition, the front dual motor 2 can be connected to the front motor left front suspension 11, the front motor right front suspension 12, the front motor left rear suspension 13 and the front motor right rear suspension 14 by bolts.

[0037] Preferably, Figure 1 and Figure 3 As shown, in the embodiment, the rear dual motor 4 can be arranged in a rearward rotation, that is, the rear dual motor 4 is arranged behind the differential. In addition, the rear dual motor 4 can adopt a T-shaped configuration, that is, the second inverter (not shown) can be arranged behind the rear dual motor 4. Such an arrangement can effectively reduce the height of the electric drive, thereby reducing the height of the vehicle body floor 7 and increasing the luggage compartment volume.

[0038] Preferably, Figure 1 and Figure 3As shown, in an embodiment, the rear dual motor 4 can be connected to the rear subframe 30 through the rear motor suspension 3. The rear motor suspension 3 may include a rear motor left front suspension 31, a rear motor right front suspension 32, a rear motor left rear suspension 33, and a rear motor right rear suspension 34. Among them, the rear motor left front suspension 31 can be arranged at the left front of the rear dual motor 4. The rear motor left front suspension 31 can be installed on the rear subframe 30 by bolts. The rear motor right front suspension 32 can be arranged at the right front of the rear dual motor 4. The rear motor right front suspension 32 can be installed on the rear subframe 30 by bolts. The rear motor left rear suspension 33 can be arranged at the left rear of the rear dual motor 4. The rear motor left rear suspension 33 can be installed on the rear subframe 30 by bolts. The rear motor right rear suspension 34 can be arranged at the right rear of the rear dual motor 4. The rear motor right rear suspension 34 can be installed on the rear subframe 30 by bolts. In addition, the rear dual motor 4 can be connected to the rear motor left front suspension 31, the rear motor right front suspension 32, the rear motor left rear suspension 33 and the rear motor right rear suspension 34 by bolts.

[0039] Further, preferably, in the embodiment, the front motor suspension 1 and the rear motor suspension 3 can adopt a two-stage vibration isolation solution, that is, a rubber bushing can be provided at the connection between the front motor suspension 1 and the front dual motors 2 and the front subframe 10, and a rubber bushing can be provided at the connection between the rear motor suspension 3 and the rear dual motors 4 and the rear subframe 30. This can greatly improve the NVH (noise, vibration and harshness) level of the vehicle.

[0040] Preferably, Figure 1 and Figure 3 As shown, in an embodiment, the high-voltage system 5 can integrate a DC-to-DC converter (DCDC) and an on-board charger (OBC). Most vehicles on the market place the high-voltage system in the front engine compartment. Such a setting will reduce the volume of the front trunk and there is a risk of fire in the high-voltage system when the vehicle collides. Some vehicles place the high-voltage system under the second row of seats. Such a setting will raise the height of the second row of the vehicle and reduce the headroom for the second row of passengers. In an embodiment, the high-voltage system 5 is arranged in a groove 50 in the spare tire compartment of the floor. Such a setting does not affect the storage space and can improve the safety of the high-voltage system 5.

[0041] Preferably, Figure 1 and Figure 2As shown, in an embodiment, the thermal management system may adopt a highly integrated solution, and the thermal management system may include a front cooling module 61 and a thermal management integrated module 62. Among them, the front cooling module 61 may be a highly integrated front cooling module, and the front cooling module 61 may be a plate-like structure. The front cooling module 61 may be arranged at the front of the front dual motor 2. Preferably, the front cooling module 61 is arranged obliquely from bottom to top in the direction close to the front dual motor 2, thereby improving the air intake efficiency and cooling capacity, and at the same time being able to increase the size of the front trunk in the height direction of the vehicle. Specifically, the upper end of the front cooling module 61 may be mounted on the vehicle body floor 7 through a crossbeam, and the lower end of the front cooling module 61 may be mounted on the front subframe 10 through bolts. The thermal management integrated module 62 may be arranged on the upper part of the front dual motor 2. The thermal management integrated module 62 may highly integrate the parts and pipelines of the heat pump system to further increase the volume of the front trunk, and ensure that the space utilization rate of the front cabin is not lower than that of an ordinary single-motor vehicle. Specifically, the thermal management integrated module 62 may be mounted on the vehicle body through a crossbeam.

[0042] Preferably, Figure 1 and Figure 4 As shown, in the embodiment, the four-motor pure electric platform configuration may further include a vehicle body floor 7. The vehicle body floor 7 may include a front cabin and a rear floor of the vehicle. The front cabin and the rear floor may be integrally die-cast, that is, the vehicle body floor 7 adopts an integral die-cast aluminum solution of the front cabin and the rear floor, thereby greatly reducing the weight and energy consumption of the vehicle.

[0043] Further, preferably, Figure 1 and Figure 4 As shown, in an embodiment, the four-motor pure electric platform configuration may further include a power battery 8. The power battery 8 may be a flat plate structure. Preferably, the power battery 8 may adopt the CTB (i.e., battery-body integration technology) solution, and the thickness of the power battery 8 is 15 mm greater than that of the CTP (module-free battery technology) solution. The power battery 8 may be embedded and installed in the vehicle body floor 7, and the power battery 8 and the vehicle body floor 7 may be connected by bolts. Such a setting can effectively increase the power of the power battery 8, increase the internal space of the passenger compartment, reduce the weight of the vehicle, and improve the collision safety performance. In addition, the upper cover of the power battery 8 may be used as the floor surface of the vehicle body floor 7, that is, the original floor sheet metal of the vehicle body floor 7 is omitted, so that the distance from the heel point of the second row of passengers to the power battery 8 can be effectively reduced, and the spatial dimensions of the passenger compartment in the height direction of the vehicle can be increased, while being compatible with the rear extra-long slide rail seats.

[0044] In addition, if Figures 1 to 4 As shown, according to a second aspect of the present invention, a vehicle is provided, the vehicle comprising the four-motor pure electric platform configuration as described above.

[0045] During use, the four-motor pure electric platform configuration increases the volume of the front trunk, optimizes the vehicle size and driving space through the arrangement of the front dual motors 2, the rear dual motors 4, the thermal management system and the high-voltage system 5. The power battery 8 is arranged on the vehicle body floor 7 to reduce the weight and energy consumption of the vehicle, increase the power of the power battery 8, and meet the requirements of endurance and vehicle lightweight.
