[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Reference below Figure 1-Figure 7 An electric drive assembly 10 according to an embodiment of the first aspect of the utility model is described.

[0034] like Figure 1-Figure 7 As shown, the electric drive assembly 10 according to the first embodiment of the utility model includes: a drive motor 11, a transmission 12, a reducer 13 and an electronic controller 14.

[0035] Specifically, the central axis of the driving shaft of the driving motor 11 is along the first direction (eg 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 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 the direction other than the Z direction (such as Figure 1 The first direction may be a direction other than the up and down direction shown in the figure, for example, the first direction may be an X direction or a Y direction. The first direction and the second direction may intersect with the Z direction, the first direction may be perpendicular to the Z direction, or the first direction may intersect with the Z direction at an acute angle or an obtuse angle, the second direction may be perpendicular to the Z direction, or the first direction may intersect with the Z direction at an acute angle or an obtuse angle.

[0037] like Figure 1 and Figure 2As shown, the height dimension of the reducer 13 in the Z direction of the vehicle 100 is relatively large. 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 located 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, so that the overall Z-direction dimension of the electric drive assembly 10 is reduced.

[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 is convenient for the arrangement of other structures in the vehicle 100 and makes the assembly of the vehicle 100 more convenient.

[0039] It is understandable 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, so that the electric controller 14 occupies a larger Z-direction space, thereby making the Z-direction space of the electric drive assembly 10 occupy a larger space. 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 electric controller 14 and the reducer 13 can also be staggered in the second direction, and the electric controller 14 and the reducer 13 can also be staggered in both the first direction and the second direction.

[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 utility model, by setting the drive motor 11, the transmission 12, the reducer 13 and the 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 size. 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, so that the user can ride more comfortably and have a better riding experience.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the electric controller 14 may be disposed on a side of the reducer 13 facing the drive motor 11 , and the electric controller 14 and the reducer 13 may be completely staggered in the first direction.

[0043] In this embodiment, the electric controller 14 is arranged on the side of the reducer 13 facing the drive motor 11. For example, the surface of the electric controller 14 facing the reducer 13 can be in contact with the surface of the reducer 13 facing the electric controller 14 or there is a certain gap, so that the electric controller 14 can be arranged relatively well in the space area formed by the reducer 13 and the drive motor 11. Arranging the electric 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 electric controller 14 and the reducer 13 are completely staggered in the first direction, that is, in the first direction, the electric 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 electric controller 14 in the Z direction and the reducer 13 can be well avoided, so that the arrangement of the electric controller 14 is more convenient. The electric 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 invention, Figure 1 As shown, in a projection plane perpendicular to the first direction, the projection of the electric controller 14 and the projection of the reducer 13 in the Z direction may at least partially overlap.

[0046] In this embodiment, the projection of the electric 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 ranges of the electric controller 14 and the reducer 13 in the Z direction can be kept partially overlapped, so that the overall height dimension of the electric control area and the reducer 13 can be reduced after assembly, 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 at least partially overlaps with the projection of the reducer 13 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 meet the partial overlap of the projections to reduce the height in the Z direction.

[0048] In some examples of the present invention, Figure 1 and Figure 2 As shown, the electric controller 14 and the drive motor 11 can move in a second direction (such as Figure 1 The second direction (as shown) is arranged, and the second direction, the first direction and the Z direction intersect each other.

[0049] The second direction, the first direction and the Z direction intersect 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, and 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 the present 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 they are arranged in the Z direction to a certain extent, making the arrangement of the electronic controller 14 and the drive motor 11 more flexible, and the drive motor 11 and the electronic controller 14 can well occupy the arrangement range of the reducer 13 in the second direction, so that the electronic controller 14 and the drive motor 11 can reasonably use the space and be assembled and arranged with the reducer 13 more compactly, 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 electric controller 14 can be arranged on the front side of the drive motor 11 in the second direction, which can meet the assembly and arrangement requirements of the electric drive assembly 10. Figure 2 As shown, 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 behind the reducer 13 in the second direction. The electronic controller 14 is arranged at the front side of the drive motor 11. This can make the drive 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 front of the reducer 13, the electronic controller 14 can also be arranged at the rear side of the drive motor 11 as needed.

[0052] In one example of the present invention, Figure 1As shown, in the 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 electric controller 14 and the reducer 13 more compact. Specifically, the arrangement range of the electric 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 electric controller 14 and the reducer 13 are assembled and arranged, the portion of the electric 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 improving space utilization.

[0054] In one example of the present invention, reference Figure 1 and Figure 2 As shown, 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 may partially overlap.

[0055] The projection of the electric controller 14 partially overlaps with the projection of the drive motor 11 in the Z direction, so that when the electric controller 14 and the drive motor 11 are assembled and arranged, the electric controller 14 can better utilize the spatial area formed by the reducer 13 and the drive motor 11 for arrangement, and the electric controller 14 can more conveniently reduce the arrangement height in the Z direction, so that the overall Z-direction size of the electric 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 invention, reference Figure 1 and Figure 2 As shown, 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 electric controller 14 is extended downwardly along the Z direction, and the projection of the electric 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 electric controller 14, the drive motor 11 and the reducer 13 more compact, and the space utilization more reasonable. 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 invention, Figure 2 As shown, 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 the present 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 the present embodiment can be suitable for vehicles with a smaller wheelbase.

[0060] In some specific examples of the present invention, Figure 2 As shown, the electric drive assembly 10 may further include a differential lock 15 , which is disposed on the side of the reducer 13 facing the drive motor 11 , and is connected to the reducer 13 , and is located in a 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, and the overall structural layout of the electric drive assembly 10 is more compact and reasonable.

[0062] In some embodiments of the present invention, Figure 1 As shown, 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, and 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 to 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 in the vehicle 100 with the subframe 30, and making more reasonable use of space.

[0064] In some embodiments of the present invention, Figure 1 As shown, 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, and the longitudinal beam of the subframe 30 of the vehicle 100 can pass through the avoidance space at the bottom of the transmission 12 to 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 in conjunction with the subframe 30 in the vehicle 100, and making more reasonable use of space.

[0066] In some embodiments of the present invention, Figure 1 As shown, in the Z direction, the bottom of the driving 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 avoidance space formed by the electric drive assembly 10 at the bottom position of the drive motor 11 and the transmission 12 can facilitate the longitudinal beams on the left and right sides of the subframe 30 to pass through so as to be assembled and fixed with the electric drive assembly 10 and the frame 20, and a larger space is reserved for the arrangement of the suspension in the first direction, so that the space utilization of the electric drive assembly 10 is more sufficient, and the ground clearance of the subframe 30 in the Z direction of the whole vehicle can be improved to a certain extent, so that the vehicle 100 has better passability, and the passenger compartment can have a larger Z-direction space, so that the user can ride more comfortably.

[0068] In some embodiments of the present invention, the electric drive assembly 10 may further include a housing, the housing forming a mounting cavity, the reducer 13, the drive motor 11 and the transmission 12 are all arranged in the mounting cavity, and the electronic controller 14 is fixedly connected to the housing.

[0069] In this embodiment, the reducer 13, the drive motor 11 and the transmission 12 are all arranged in the installation cavity, which can reduce the number of connectors and space occupied when the parts are connected separately, making the overall structure of the electric drive assembly 10 more compact, making the electric drive assembly 10 more integrated, meeting the need for lightweight, and providing a larger layout space for the arrangement of other vehicle 100 systems after the electric drive assembly 10 is assembled and fixed in the vehicle 100, making the assembly and arrangement of the vehicle 100 more convenient. Furthermore, the differential lock 15 can also be arranged in the installation cavity, making the overall structure of the electric drive assembly 10 more compact.

[0070] In this embodiment, the electric controller 14 is arranged separately and fixedly connected to the housing, so that the operation of the electric controller 14 can be more stable and safe, and the maintenance and replacement of the electric controller 14 are convenient.

[0071] Reference below Figure 1-Figure 7 A vehicle 100 according to an embodiment of the second aspect of the present invention is described.

[0072] like Figure 1-Figure 7As shown, a vehicle 100 according to an embodiment of the present utility model includes an electric drive assembly 10 according to an embodiment of the first aspect of the present utility model.

[0073] According to the vehicle 100 of the embodiment of the utility model, by setting the electric drive assembly 10 of the first aspect embodiment mentioned above, 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. 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, so that the user can ride more comfortably and have a better riding experience.

[0074] In some embodiments of the present invention, Figure 3-Figure 7 As shown, the vehicle 100 may further include: a frame 20, a rear floor 40 and a sub-frame 30, wherein the rear floor 40 is fixed to the frame 20, the electric drive assembly 10 is fixed to the sub-frame 30 through front and rear end suspensions, the sub-frame 30 is fixed to the frame 20 through connection points on all sides, and the sub-frame 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 on the sub-frame 30 through front and rear suspensions can reduce the transmission of vibrations 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 sub-frame 30, has a simple structure, and is easy to assemble.

[0076] The following will refer to Figure 1-Figure 7 A vehicle 100 according to a specific embodiment of the present invention is described.

[0077] like Figure 1-Figure 7 As shown, 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.
