All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] like Figure 1 and Figure 2 As shown, in Embodiment 1, the drive device includes: an engine 10, a first drive shaft 20, a first motor 30, a second motor 40, a first transmission structure 50, and a power output shaft 60. The first drive shaft 20 is driven by the engine 10. The first motor 30 includes a first housing, a first rotor 31, and a first stator 32. The first stator 32 is disposed within the first housing, and the first rotor 31 is rotatably disposed within the first stator 32. The first drive shaft 20 is driven by the first rotor 31. The second motor 40 includes a second housing, a second rotor 41, and a second stator 42. The second stator 42 is disposed within the second housing, and the second rotor 41 is rotatably disposed within the second stator 42. The first transmission structure 50 is disposed within the second rotor 41. The first transmission structure 50 includes a first planetary carrier 51, first planetary gears 52, a first sun gear 53, and a first ring gear 54. The first sun gear 53 is coaxially arranged with the second rotor 41 and is driven by it. The first planetary gear 52 is disposed between the first sun gear 53 and the first ring gear 54. The first planetary gear 52 can drive the power output shaft 60 to rotate.

[0033] Applying the technical solution of Embodiment 1, the drive device includes an engine 10, a first drive shaft 20, a first motor 30, a second motor 40, a first transmission structure 50, and a power output shaft 60. The engine 10 drives the first drive shaft 20 to rotate, which in turn drives the first rotor 31 to rotate relative to the first stator 32, thereby generating electricity. The rotation of the second rotor 41 drives the first sun gear 53 to rotate, which in turn drives the first planetary gears 52 to rotate relative to the first ring gear 54, which in turn drives the first planetary carrier 51 to rotate, thus enabling the first planetary carrier 51 to drive the power output shaft 60 to rotate. By placing the first transmission structure 50 within the second rotor 41, the first transmission structure 50 occupies less external space, thereby reducing the space required for the drive device. Therefore, the technical solution of Embodiment 1 effectively solves the problem of large space occupation in related technologies for drive devices.

[0034] It should be noted that the first gear ring is fixed.

[0035] The first transmission structure 50 occupies less external space, meaning that during installation, there is no need to separately set up a mounting position for the first transmission structure 50 on the drive unit's housing, thereby reducing the size of the housing. The first gear ring 54 can be disposed on the second housing or on the housing.

[0036] The engine 10 can drive the first motor 30 to generate electricity, which can power the battery or directly power the second motor 40. The battery can also directly drive the second motor 40.

[0037] The drive unit is a longitudinally mounted range extender transmission. It meets vehicle requirements and features strong power, good stability, and low fuel consumption. The drive unit has multiple modes including idle-speed generator, pure electric, and series transmission, and is characterized by its compact structure, excellent expandability, strong power, good stability, and low fuel consumption.

[0038] The drive unit also includes a first connecting shaft and a second connecting shaft, which are arranged perpendicularly. One end of the first connecting shaft is connected to the first sun gear 53, and the other end of the first connecting shaft is connected to the middle of the second connecting shaft. Both ends of the second connecting shaft are connected to the second rotor 41.

[0039] like Figure 1 As shown, in Embodiment 1, the driving device further includes a connecting rod 150, which is connected to the first rotor 31. The first drive shaft 20 is driven by the connecting rod 150. The first drive shaft 20 can drive the connecting rod 150 to rotate, and thus the connecting rod 150 can drive the first rotor 31 to rotate.

[0040] In Embodiment 1, the first drive shaft 20 is directly connected to the connecting rod 150. The first motor 30 and the second motor 40 are coaxially arranged. The power output shaft 60 drives the front wheel structure.

[0041] The difference between Embodiment 2 and Embodiment 1 is that a second transmission structure 70 is provided between the first drive shaft 20 and the connecting rod 150.

[0042] like Figure 2 As shown, in Embodiment 2, the drive device further includes a second transmission structure 70. The second transmission structure 70 includes a second planetary carrier 71, second planetary gears 72, a second sun gear 73, and a second ring gear 74. The first drive shaft 20 is driven and coaxially arranged with the second planetary carrier 71. The second planetary gears 72 are connected to the second planetary carrier 71 and are positioned between the second sun gear 73 and the second ring gear 74. The second sun gear 73 is driven and coaxially arranged with the first rotor 31. The first drive shaft 20 can drive the second planetary carrier 71 to rotate, which in turn drives the second planetary gears 72 to rotate, thereby enabling the second planetary gears 72 to drive the second sun gear 73 to rotate, and ultimately, the second sun gear 73 to drive the first rotor 31 to rotate.

[0043] It should be noted that the second gear ring 74 is fixedly installed. The second gear ring 74 can be installed on the first housing or on the enclosure.

[0044] The drive unit also includes a third connecting shaft, through which the second sun gear 73 is connected to the connecting rod 150.

[0045] like Figure 2 As shown, in Embodiment 2, the second transmission structure 70 is disposed within the first rotor 31. This allows the second transmission structure 70 to occupy less external space, thereby allowing the drive device to occupy less space.

[0046] like Figure 1 and Figure 2 As shown, in Embodiment 1, the drive unit further includes a differential 80, which is driven by the power output shaft 60. The drive unit also includes a third transmission structure 90, which includes a first transmission wheel 91 and a second drive shaft 92. The first transmission wheel 91 is mounted on the second drive shaft 92 and meshes with the differential 80. The second drive shaft 92 is driven by a first planetary carrier 51. The first planetary carrier 51 can drive the second drive shaft 92 to rotate, which in turn drives the first transmission wheel 91 to rotate. This, in turn, allows the first transmission wheel 91 to drive the differential 80, which in turn drives the power output shaft 60 to rotate.

[0047] It should be noted that the power output shaft 60 includes two shafts, which drive the two wheels of the front wheel structure or the two wheels of the rear wheel structure respectively.

[0048] like Figure 1 As shown, in Embodiment 1, the driving device further includes a second transmission wheel 100, and the third transmission structure 90 further includes a third transmission wheel 93 disposed on the second drive shaft 92. The first transmission wheel 91 and the third transmission wheel 93 are spaced apart. The second transmission wheel 100 is connected to and coaxially disposed with the first planetary carrier 51, and the second transmission wheel 100 and the third transmission wheel 93 mesh. The first planetary carrier 51 can drive the second transmission wheel 100 to rotate, which in turn can drive the third transmission wheel 93 to rotate, thereby the third transmission wheel 93 can drive the second drive shaft 92 to rotate.

[0049] The difference between Embodiment 3 and Embodiment 2 is that: a third transmission wheel 93 is not provided, and a fourth transmission structure 110 is provided between the first planetary carrier 51 and the second drive shaft 92. The first motor and the second motor are coaxially arranged.

[0050] like Figure 3 As shown, in Embodiment 3, the drive device further includes a fourth transmission structure 110. The fourth transmission structure 110 includes a third planetary carrier 111, a third planetary gear 112, a third sun gear 113, and a third ring gear 114. The third planetary carrier 111 is connected to the second drive shaft 92. The third planetary gear 112 is disposed between the third sun gear 113 and the third ring gear 114. The third sun gear 113 is connected to and coaxially arranged with the first planetary carrier 51. The first planetary carrier 51 can drive the third sun gear 113 to rotate, which in turn drives the third planetary gear 112 to rotate relative to the third ring gear 114. Consequently, the third planetary gear 112 can drive the third planetary carrier 111 to rotate, and the third planetary carrier 111 can drive the second drive shaft 92 to rotate.

[0051] The difference between Embodiment 4 and Embodiment 3 is that: the second transmission structure 70 is not provided, and the fourth transmission wheel 120, the fifth transmission wheel 130 and the third drive shaft 140 are provided between the first drive shaft 20 and the connecting rod 150.

[0052] like Figure 4As shown, in Embodiment 4, the drive device further includes a fourth transmission wheel 120, a fifth transmission wheel 130, and a third drive shaft 140. The fourth transmission wheel 120 meshes with the fifth transmission wheel 130. The fourth transmission wheel 120 is located at the end of the first drive shaft 20 away from the engine 10. The fifth transmission wheel 130 is located on the third drive shaft 140. The third drive shaft 140 is connected to and coaxially arranged with the first rotor 31, and is parallel to the first drive shaft 20. The first drive shaft 20 can drive the fourth transmission wheel 120 to rotate, which in turn drives the fifth transmission wheel 130 to rotate, so that the fifth transmission wheel 130 drives the third drive shaft 140 to rotate, thereby driving the first rotor 31 to rotate.

[0053] like Figure 3 , Figure 4 , Figure 7 as well as Figure 9 As shown, in Embodiments 3, 4, 7 and 9, there is a gap between the axis of the second motor 40 and the axis of the first motor 30.

[0054] The difference between Embodiment 5 and Embodiment 2 is that the differential 80 and the third transmission structure 90 are located on the side of the second motor 40 away from the first motor 30.

[0055] like Figure 5 As shown, in Embodiment 5, the power output shaft 60 drives the rear wheel structure.

[0056] The difference between Embodiment Six and Embodiment Three is that the differential 80 and the third transmission structure 90 are located on the side of the second motor 40 away from the first motor 30, and the first motor 30 and the second motor 40 are coaxially arranged.

[0057] like Figure 6 As shown, in Embodiment Six, the power output shaft 60 drives the rear wheel structure.

[0058] The difference between Embodiment 7 and Embodiment 4 is that the differential 80 and the third transmission structure 90 are located on the side of the second motor 40 away from the first motor 30.

[0059] like Figure 7 As shown, in Embodiment 7, the power output shaft 60 drives the rear wheel structure.

[0060] The difference between Embodiment 8 and Embodiment 1 is that the differential 80 and the third transmission structure 90 are located on the side of the second motor 40 away from the first motor 30.

[0061] like Figure 8 As shown, in Embodiment 8, the power output shaft 60 drives the rear wheel structure.

[0062] The difference between Embodiment Nine and Embodiment One is that: a third transmission wheel 93 is not provided, and a fourth transmission structure 110 is provided between the first planetary carrier 51 and the second drive shaft 92. The first motor 30 and the second motor 40 are not coaxial. The power output shaft 60 drives the rear wheel structure.

[0063] like Figure 10 As shown, the difference between Embodiment 10 and Embodiment 6 is that the second transmission structure 70 is not provided.

[0064] The vehicle in Embodiment 1 includes a vehicle body, a drive unit, a front wheel structure, and a rear wheel structure. The drive unit, front wheel structure, and rear wheel structure are all mounted on the vehicle body. The drive unit is the one described above, and its first planetary carrier 51 engages with either the front wheel structure or the rear wheel structure. The first transmission structure 50 of the drive unit is housed within the second rotor 41, reducing the external space occupied by the first transmission structure 50 and allowing for a more compact drive unit structure. Vehicles equipped with the aforementioned drive unit also possess the advantages described above.

[0065] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0066] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0067] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0068] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
