[0033] The electric drive assembly 10 according to the first embodiment of the present application will be described below with reference to FIG. 1 to FIG. 7 .

[0034] As shown in FIG. 1 to FIG. 7 , the electric drive assembly 10 according to the embodiment of the first aspect of the present application includes: a drive motor 11 , a transmission 12 , a reducer 13 and an electronic controller 14 .

[0035] Specifically, the central axis of the drive shaft of the drive motor 11 extends along the first direction (the left-right direction as shown in Figure 2); the transmission 12 is connected to the drive motor 11 and is located on one side of the drive motor 11 in the first direction; the reducer 13 is connected to the transmission 12 and is arranged on the side of the transmission 12 facing the drive motor 11; the electronic controller 14 and the reducer 13 are staggered in the first direction and / or the second direction, and the first direction, the second direction and the Z direction intersect each other.

[0036] In this embodiment, the central axis of the drive shaft of the drive motor 11 is extended along the first direction, and the transmission 12 is connected to the drive motor 11 and is located on one side of the drive motor 11 in the first direction. The output shaft of the drive motor 11 can be relatively directly connected to the transmission 12 in the first direction, thereby reducing the number of transmission components and simplifying the arrangement of the transmission direction to a certain extent, making the overall structure of the electric drive assembly 10 more compact. The first direction in this embodiment can refer to a direction other than the Z direction (the up and down direction as shown in Figure 1), for example, the first direction can be the X direction or the Y direction. The first direction and the second direction intersect with the Z direction, the first direction can be perpendicular to the Z direction, and the first direction can also intersect with the Z direction at an acute angle or an obtuse angle, the second direction can be perpendicular to the Z direction, and the first direction can also intersect with the Z direction at an acute angle or an obtuse angle.

[0037] As shown in Figures 1 and 2, the reducer 13 has a relatively large height dimension in the Z direction of the vehicle 100. In this embodiment, the reducer 13 is connected to the transmission 12 and is arranged on the side of the transmission 12 facing the drive motor 11. That is, the reducer 13 and the transmission 12 are arranged along the first direction and the drive motor 11 and the transmission 12 are arranged along the first direction. In this way, when the electric drive assembly 10 is arranged and installed, the transmission 12 can be partially or completely within the arrangement height range of the reducer 13, and the drive motor 11 can also be partially within the arrangement height range of the reducer 13, thereby reducing the additional space occupied by the drive motor 11 and the transmission 12 in the Z direction, and reducing the overall Z-direction size of the electric drive assembly 10.

[0038] In this embodiment, the transmission 12 is arranged together with the electronic controller 14, the reducer 13 and the drive motor 11, so that the electric drive assembly 10 is more integrated. The electric drive assembly 10 can occupy less space when arranged in the vehicle 100, which facilitates the arrangement of other structures in the vehicle 100 and makes the assembly of the vehicle 100 more convenient.

[0039] It is understood that in the related art, when the electric drive assembly 10 is arranged, the electric controller 14 is usually arranged above the reducer 13 in the Z direction. This allows the electric controller 14 to occupy a larger Z-direction space, thereby increasing the Z-direction space occupied by the electric drive assembly 10. In this embodiment, the electric controller 14 and the reducer 13 are staggered in the first direction and / or the second direction. The electric controller 14 and the reducer 13 can be staggered in the first direction, the second direction, or both the first and second directions.

[0040] When the electric drive assembly 10 is assembled and arranged, the electric controller 14 can be arranged downward relative to the upper end surface of the reducer 13, so that the height range of the electric controller 14 in the Z direction can partially overlap with the height range of the reducer 13 in the Z direction, thereby reducing the space occupied by the electric controller 14 in the Z direction when the electric drive assembly 10 is assembled and arranged, and greatly reducing the Z-direction height dimension of the electric drive assembly 10. As a result, when the vehicle 100 is processed and manufactured, the passenger compartment can have a larger Z-direction space, making the user more comfortable and having a better riding experience.

[0041] According to the electric drive assembly 10 of the embodiment of the present application, by providing a drive motor 11, a transmission 12, a reducer 13 and an electronic controller 14, the electronic controller 14 and the reducer 13 are staggered in the first direction and / or the second direction, so that the overall structural integration of the drive motor 11 is higher, the overall structural arrangement is more compact and reasonable, and has a smaller Z-direction dimension. Therefore, when the electric drive assembly 10 is arranged in the vehicle 100, the passenger compartment of the vehicle 100 can have a larger Z-direction space, making the user more comfortable and having a better riding experience.

[0042] In some embodiments of the present application, as shown in FIG1 and FIG2 , the electronic controller 14 may be disposed on a side of the reducer 13 facing the drive motor 11 , and the electronic controller 14 and the reducer 13 may be completely staggered in the first direction.

[0043] In this embodiment, the electronic controller 14 is arranged on the side of the reducer 13 facing the drive motor 11. For example, the surface of the side of the electronic controller 14 facing the reducer 13 can be in contact with the surface of the side of the reducer 13 facing the electronic controller 14 or there can be a certain gap, so that the electronic controller 14 can be arranged relatively well in the space area formed by the reducer 13 and the drive motor 11. Arranging the electronic controller 14 and the drive motor 11 on the same side of the reducer 13 can better utilize the space and make the overall structural layout of the electric drive assembly 10 more compact and reasonable.

[0044] The electronic controller 14 and the reducer 13 are completely staggered in the first direction, that is, in the first direction, the electronic controller 14 and the reducer 13 are arranged at intervals. When the electric drive assembly 10 is assembled and arranged, the interference between the arrangement position of the electronic controller 14 in the Z direction and the reducer 13 can be well avoided, so that the arrangement of the electronic controller 14 is more convenient. The electronic controller 14 can more conveniently reduce the Z-direction arrangement height in the electric drive assembly 10, so that the overall Z-direction size of the electric drive assembly 10 is effectively reduced, and then after the electric drive assembly 10 is arranged in the vehicle 100, the rear floor 40 does not need to be partially lifted to avoid the electric drive assembly 10, so that the passenger compartment has a larger Z-direction space, making the user more comfortable.

[0045] In one embodiment of the present application, as shown in FIG1 , in a projection plane perpendicular to the first direction, the projection of the electronic controller 14 and the projection of the speed reducer 13 in the Z direction may at least partially overlap.

[0046] In this embodiment, the projection of the electronic controller 14 in the projection plane is set to at least partially overlap with the projection of the reducer 13, so that the arrangement height range of the electronic controller 14 and the reducer 13 in the Z direction can be kept partially overlapping, so that the overall height dimension of the electronic control area and the reducer 13 after assembly can be reduced, thereby reducing the overall Z-direction dimension of the electric drive assembly 10, and further allowing the passenger compartment to have a larger space, making the user more comfortable.

[0047] The projection of the electric controller 14 and the projection of the reducer 13 at least partially overlap in the Z direction, that is, the projection of the electric controller 14 can completely overlap with the projection of the reducer 13, and the arrangement height range of the electric controller 14 in the Z direction can completely fall within the arrangement height range of the reducer 13 in the Z direction. During actual assembly and arrangement, the electric controller 14 and the reducer 13 can be reasonably arranged as needed to ensure that the projections partially overlap to reduce the Z-direction height.

[0048] In some examples of the present application, as shown in FIG. 1 and FIG. 2 , the electronic controller 14 and the drive motor 11 may be arranged along a second direction (the second direction shown in FIG. 1 ), and the second direction, the first direction, and the Z direction intersect with each other.

[0049] The second direction, the first direction and the Z direction intersect with each other. The second direction can intersect with the first direction, the second direction can intersect with the Z direction, and the first direction can intersect with the Z direction. Specifically, the second direction can be perpendicular to the first direction or intersect with the first direction at an acute angle / obtuse angle. The second direction can also be perpendicular to the Z direction or intersect with the Z direction at an acute angle / obtuse angle. The first direction can also be perpendicular to the Z direction or intersect with the Z direction at an acute angle / obtuse angle.

[0050] In this embodiment, the electronic controller 14 and the drive motor 11 are arranged in the second direction, which can reduce the interference between the electronic controller 14 and the drive motor 11 when arranged in the Z direction to a certain extent, making the arrangement of the electronic controller 14 and the drive motor 11 more flexible. The drive motor 11 and the electronic controller 14 can well occupy the arrangement range area of ​​the reducer 13 in the second direction, so that the electronic controller 14 and the drive motor 11 can reasonably utilize the space and be assembled and arranged more compactly with the reducer 13, thereby making the overall structure of the electric drive assembly 10 more compact to a certain extent, reducing the space occupied by the electric drive assembly 10, and facilitating the assembly and arrangement of the electric drive assembly 10 and other structural parts in the vehicle 100.

[0051] Furthermore, the electronic controller 14 can be arranged on the front side of the drive motor 11 in the second direction, which can meet the assembly and layout requirements of the electric drive assembly 10. Referring to Figure 2, in this embodiment, the drive motor 11 and the transmission 12 need to be connected in transmission, and the transmission 12 is arranged at a position rearward of the reducer 13 in the second direction. Arranging the electronic controller 14 on the front side of the drive motor 11 can make the transmission connection between the drive motor 11 and the transmission 12 more convenient, and make the layout of the electric drive assembly 10 more compact and reasonable. Of course, when the transmission 12 is arranged in a position forward of the reducer 13, the electronic controller 14 can also be arranged on the rear side of the drive motor 11 as needed.

[0052] In an example of the present application, as shown in FIG. 1 , in a direction from the driving motor 11 toward the electric controller 14 , the electric controller 14 may extend obliquely downward along the Z direction.

[0053] This can make the arrangement of the electronic controller 14 and the reducer 13 more compact. Specifically, the arrangement range of the electronic controller 14 in the second direction and the Z direction has a larger overlapping range with the arrangement range of the reducer 13 in the second direction and the Z direction. Therefore, after the electronic controller 14 and the reducer 13 are assembled and arranged, the portion of the electronic controller 14 protruding from the reducer 13 in the Z direction and the second direction is smaller, making the overall structural arrangement of the electric drive assembly 10 more compact and the space utilization rate higher.

[0054] In an example of the present application, referring to FIG. 1 and FIG. 2 , in a projection plane perpendicular to the second direction, the projection of the electric controller 14 and the projection of the drive motor 11 in the Z direction may partially overlap.

[0055] The projection of the electronic controller 14 partially overlaps with the projection of the drive motor 11 in the Z direction, so that when the electronic controller 14 and the drive motor 11 are assembled and arranged, the electronic controller 14 can better utilize the spatial area formed by the reducer 13 and the drive motor 11 for arrangement. The electronic controller 14 can more conveniently lower the arrangement height in the Z direction, so that the overall Z direction size of the electronic controller 14 and the drive motor 11 after assembly and arrangement can be reduced to a certain extent, thereby reducing the Z direction size of the electric drive assembly 10, so that after the electric drive assembly 10 is installed in the vehicle 100, the passenger compartment can have a larger Z direction space, thereby making the user more comfortable.

[0056] In one example of the present application, referring to Figures 1 and 2, in the direction from the drive motor 11 toward the electric controller 14, the electric controller 14 can extend downwardly along the Z direction, and in the projection plane perpendicular to the second direction, the projection of the electric controller 14 and the projection of the drive motor 11 in the Z direction can partially overlap.

[0057] In this embodiment, the electronic controller 14 is extended downwardly along the Z direction, and the projection of the electronic controller 14 in the projection plane perpendicular to the second direction partially overlaps with the projection of the drive motor 11 in the Z direction. This can make the assembly and arrangement of the electronic controller 14, the drive motor 11 and the reducer 13 more compact, and the space utilization more reasonable, so that the overall structural arrangement of the electric drive assembly 10 is more compact and compact, and the arrangement of the electric drive assembly 10 in the vehicle 100 is more convenient. The Z-direction dimension of the electric drive assembly 10 is smaller, so that after the electric drive assembly 10 is assembled and arranged in the vehicle 100, the Z-direction space of the passenger compartment of the vehicle 100 can be better improved, making the user more comfortable.

[0058] In some specific embodiments of the present application, as shown in FIG. 2 , the thickness dimension of the reducer 13 in the first direction is smaller than the length dimension of the reducer 13 in the second direction.

[0059] In this embodiment, the thickness dimension of the reducer 13 in the first direction is set to be smaller than the length dimension of the reducer 13 in the second direction. This allows the size of the overall structure of the electric drive assembly 10 in the first direction to be maintained within a smaller size range when the electric drive assembly 10 is assembled and arranged, so that the overall structural size of the electric drive assembly 10 in the first direction is smaller after being arranged and assembled in the vehicle 100, thereby providing good space for the arrangement of other structures in the vehicle 100. For example, the suspension can have a larger installation and arrangement space in the first direction, making the assembly and arrangement of the vehicle 100 more convenient. The electric drive assembly 10 of this embodiment can be suitable for vehicles with smaller wheelbases.

[0060] In some specific examples of the present application, as shown in Figure 2, the electric drive assembly 10 may also include a differential lock 15, which is arranged on the side of the reducer 13 facing the drive motor 11. The differential lock 15 is connected to the reducer 13 and is located in the space formed by the drive motor 11, the reducer 13 and the electronic controller 14.

[0061] In this embodiment, the differential lock 15 is arranged in the space formed by the drive motor 11, the reducer 13 and the electronic controller 14, so that the space can be reasonably and fully utilized, making the overall structural layout of the electric drive assembly 10 more compact and reasonable.

[0062] In some embodiments of the present application, as shown in FIG. 1 , in the Z direction, the bottom of the driving motor 11 may be higher than the bottom of the reducer 13 .

[0063] The bottom of the drive motor 11 is set to be higher than the bottom of the reducer 13, so that the electric drive assembly 10 forms a larger avoidance space at the bottom position of the drive motor 11. The longitudinal beam of the subframe 30 of the vehicle 100 can pass through the avoidance space at the bottom of the drive motor 11 and be assembled and fixed with the electric drive assembly 10 and the frame 20, so that the space in the electric drive assembly 10 can be more fully utilized, making it more convenient to arrange the electric drive assembly 10 and the subframe 30 in the vehicle 100, and making more reasonable use of space.

[0064] In some embodiments of the present application, as shown in FIG. 1 , the bottom of the transmission 12 may be higher than the bottom of the speed reducer 13 .

[0065] In this way, a larger avoidance space can be formed for the electric drive assembly 10 at the bottom of the transmission 12. The longitudinal beam of the subframe 30 of the vehicle 100 can pass through the avoidance space at the bottom of the transmission 12 and be assembled and fixed with the electric drive assembly 10 and the frame 20, so that the space in the electric drive assembly 10 can be more fully utilized, making it more convenient to arrange the electric drive assembly 10 and the subframe 30 in the vehicle 100, and making more reasonable use of space.

[0066] In some embodiments of the present application, as shown in FIG. 1 , in the Z direction, the bottom of the drive motor 11 may be higher than the bottom of the reducer 13 , and the bottom of the transmission 12 may be higher than the bottom of the reducer 13 .

[0067] In this embodiment, by setting the bottom of the drive motor 11 to be higher than the bottom of the reducer 13 and the bottom of the transmission 12 to be higher than the bottom of the reducer 13, the electric drive assembly 10 forms an avoidance space at the bottom position of the drive motor 11 and the transmission 12. This can facilitate the passage of the left and right longitudinal beams of the subframe 30 for assembly and fixation with the electric drive assembly 10 and the frame 20, and reserve a larger space for the arrangement of the suspension in the first direction, so that the space utilization of the electric drive assembly 10 is more sufficient. To a certain extent, the ground clearance of the subframe 30 in the Z direction of the entire vehicle can be improved, so that the vehicle 100 has better passability and the passenger compartment can have a larger Z-direction space, thereby making the user more comfortable.

[0068] In some embodiments of the present application, the electric drive assembly 10 may further include a shell having an installation cavity, in which the reducer 13, the drive motor 11 and the transmission 12 are all disposed, and the electronic controller 14 is fixedly connected to the shell.

[0069] In this embodiment, the reducer 13, drive motor 11, and transmission 12 are all located within the mounting cavity. This reduces the number of connectors and space required for separate connections, making the overall structure of the electric drive assembly 10 more compact and integrated, meeting the requirements for lightweighting. Once the electric drive assembly 10 is assembled and secured in the vehicle 100, it provides more space for the layout of other vehicle 100 systems, making the assembly and layout of the vehicle 100 more convenient. Furthermore, the differential lock 15 can also be located within the mounting cavity, further compacting the overall structure of the electric drive assembly 10.

[0070] In this embodiment, the electronic controller 14 is arranged separately and fixedly connected to the housing, which can make the operation of the electronic controller 14 more stable and safe, and facilitate the maintenance and replacement of the electronic controller 14.

[0071] A vehicle 100 according to an embodiment of the second aspect of the present application will be described below with reference to FIG. 1 to FIG. 7 .

[0072] As shown in FIG. 1 to FIG. 7 , a vehicle 100 according to an embodiment of the present application includes an electric drive assembly 10 according to an embodiment of the first aspect of the present application.

[0073] According to the vehicle 100 of the embodiment of the present application, the electric drive assembly 10 of the above-mentioned first aspect embodiment is arranged, and the electric drive assembly 10 is provided with a drive motor 11, a transmission 12, a reducer 13 and an electronic controller 14. The drive motor 11 and the electronic controller 14 are arranged on the same side of the reducer 13, and the electronic controller 14 and the reducer 13 are staggered in the first direction and / or the second direction, so that the overall structural integration of the drive motor 11 is higher, the overall structural arrangement is more compact and reasonable, and has a smaller Z-direction dimension, so that when the electric drive assembly 10 is arranged in the vehicle 100, the passenger compartment of the vehicle 100 can have a larger Z-direction space, so that the user can ride more comfortably and have a better riding experience.

[0074] In some embodiments of the present application, as shown in Figures 3 to 7, the vehicle 100 may further include: a frame 20, a rear floor 40 and a subframe 30. The rear floor 40 is fixed to the frame 20, and the electric drive assembly 10 is fixed to the subframe 30 through front and rear end suspensions. The subframe 30 is fixed to the frame 20 through connection points on all four sides. The subframe 30 and the electric drive assembly 10 are located on the lower side of the rear floor 40.

[0075] Fixing the electric drive assembly 10 to the subframe 30 through front and rear suspension can reduce the transmission of vibration generated during the operation of the electric drive assembly 10 to the frame 20, thereby improving the riding comfort of the vehicle 100. The electric drive assembly 10 is fixedly connected to the frame 20 through the subframe 30, with a simple structure and easy assembly.

[0076] A vehicle 100 according to a specific embodiment of the present application will be described below with reference to FIG. 1 to FIG. 7 .

[0077] As shown in FIG. 1 to FIG. 7 , the vehicle 100 in this embodiment may be an off-road vehicle, a pickup truck, a large SUV (Sports Utility Vehicle), or other new energy vehicle models.

[0078] The vehicle 100 includes a frame 20, a rear floor 40, a subframe 30, and an electric drive assembly 10. In this embodiment, the vehicle 100 is a rear-wheel drive vehicle, and the electric drive assembly 10 is arranged at the rear of the vehicle 100. Specifically, the electric drive assembly 10 is fixed to the subframe 30 via a suspension, and the subframe 30 is fixed to the frame 20. The rear floor 40 is fixed to the frame 20 and is located above the electric drive assembly 10 and the subframe 30.

[0079] The electric drive assembly 10 includes a housing, a transmission 12, a reducer 13, a differential lock 15, a drive motor 11 and an electronic controller 14. The housing is formed with a mounting cavity, and the transmission 12, the reducer 13, the differential lock 15 and the drive motor 11 are all arranged in the mounting cavity. The electronic controller 14 is fixedly connected to the housing by fasteners, and the housing is fixed to the subframe 30 by suspension.
