[0030] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] This application provides a drive assembly 100, referring to... Figure 1 As shown, the drive assembly includes a housing 6, a first drive motor 11, a second drive motor 12, a first transmission component 21, and a second transmission component 22. The first drive motor 11 and the first transmission component 21 are connected in a transmission manner, and the second drive motor 12 and the second transmission component 22 are also connected in a transmission manner. A first accommodating cavity 61 and a second accommodating cavity 62 are provided at intervals along the second direction Y in the housing 6. The first drive motor 11 and the second transmission component 22 are arranged at intervals along the first direction X in the first accommodating cavity 61, and the second drive motor 12 and the first transmission component 21 are arranged at intervals along the first direction X in the second accommodating cavity 62. The first drive motor 11 and the second transmission component 22 at least partially overlap in the second direction Y, and the second drive motor 12 and the first transmission component 21 at least partially overlap in the second direction Y. The first direction X is perpendicular to the second direction Y.

[0032] According to the embodiments of this application, by at least partially overlapping the first drive motor 11 and the second transmission component 22 in the first accommodating cavity 61 in the second direction Y, and by at least partially overlapping the second drive motor 12 and the first transmission component 21 in the second accommodating cavity 62 in the second direction Y, the space occupied by the drive assembly 100 in the second direction Y can be reduced, and the structure of the drive assembly 100 is more compact.

[0033] Wherein, the second direction Y is the axial direction of the first drive motor 11 and the second drive motor 12.

[0034] In this embodiment of the application, a first drive motor 11, a second drive motor 12, a first transmission component 21, and a second transmission component 22 are provided inside the housing 6. The housing 6 can protect the first drive motor 11, the second drive motor 12, the first transmission component 21, and the second transmission component 22 from damage caused by external impacts, and can also prevent foreign objects from entering the housing 6 and affecting the operation of the drive assembly 100.

[0035] In some embodiments, refer to Figure 7 As shown, along the second direction Y, the size of the first drive motor 11 is L1, and the size of the second transmission component 22 is L2, where L1 ≥ L2.

[0036] In this embodiment, when L1≥L2, the dimension of the drive assembly 100 in the second direction Y is affected by the axial dimension of the first drive motor 11. Thus, when using the first drive motor 11 that meets the power requirements, the drive assembly 100 can set its dimension in the second direction Y to be smaller.

[0037] In some embodiments, refer to Figure 7 As shown, along the second direction Y, the size of the second drive motor 12 is L3, and the size of the first transmission component 21 is L4, where L3 ≥ L4.

[0038] In this embodiment, when L3≥L4, the dimension of the drive assembly 100 in the second direction Y is affected by the axial dimension of the second drive motor 12. Thus, when using the second drive motor 12 that meets the power requirements, the drive assembly 100 can set a smaller dimension in the second direction Y.

[0039] In some embodiments, refer to Figure 7 As shown, along the second direction Y, the size of the first drive motor 11 is L1, the size of the second transmission component 22 is L2, the size of the second drive motor 12 is L3, and the size of the first transmission component 21 is L4, where L1≥L2 and L3≥L4.

[0040] In this embodiment, when L1≥L2 and L3≥L4, the size of the drive assembly 100 in the second direction Y is affected by the axial dimensions of the first drive motor 11 and the second drive motor 12. Thus, when using the first drive motor 11 and the second drive motor 12 that meet the power requirements, the size of the drive assembly 100 in the second direction Y can be set to be smaller.

[0041] In some embodiments, refer to Figure 3As shown, along the second direction Y, the size of the first accommodating cavity 61 is L5, where 140mm ≤ L5 ≤ 200mm. In this embodiment, when the size L5 of the first accommodating cavity 61 in the second direction Y is within the above range, the size of the drive assembly 100 in the second direction Y can be effectively shortened.

[0042] Furthermore, the preferred range of L5 is 160mm ≤ L5 ≤ 180mm. In this embodiment, when the dimension L5 of the first accommodating cavity 61 in the second direction Y is within the above range, the drive assembly 100 can shorten its dimension in the second direction Y while taking into account both the volume requirements of the drive assembly 100 and the volume requirements of the first drive motor 11.

[0043] Understandably, L5 can be set according to usage requirements. For example, L5 can be any value among 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, and 200mm, or any range between any two values.

[0044] In some embodiments, refer to Figure 3 As shown, along the second direction Y, the size of the second accommodating cavity 62 is L6, where 140mm ≤ L6 ≤ 200mm. In this embodiment, when the size L6 of the second accommodating cavity 62 in the second direction Y is within the above range, the size of the drive assembly 100 in the second direction Y can be effectively shortened.

[0045] Furthermore, the preferred range of L6 is 160mm ≤ L6 ≤ 180mm. In this embodiment, when the dimension L6 of the second accommodating cavity 62 in the second direction Y is within the above range, the drive assembly 100 can shorten the axial dimension of the drive assembly 100 while taking into account the volume requirements of the drive assembly 100 and the volume requirements of the second drive motor 12.

[0046] Understandably, L6 can be set according to usage requirements. For example, L6 can be any value among 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, and 200mm, or any range between any two values.

[0047] In some embodiments, refer to Figure 3 As shown, along the second direction Y, the size of the first accommodating cavity 61 is L5, and the size of the second accommodating cavity 62 is L6, where 140mm ≤ L5 ≤ 200mm and 140mm ≤ L6 ≤ 200mm. In this embodiment, when the sizes L5 and L6 of the first accommodating cavity 61 and the second accommodating cavity 62 in the second direction Y are within the above range, the size of the drive assembly 100 in the second direction Y can be effectively shortened.

[0048] Furthermore, preferably, L5 is in the range of 160mm ≤ L5 ≤ 180mm, and L6 is in the range of 160mm ≤ L6 ≤ 180mm. In this embodiment, when the dimensions L5 and L6 of the first accommodating cavity 61 and the second accommodating cavity 62 in the second direction Y are within the above ranges, the drive assembly 100 can shorten its dimensions in the second direction Y while taking into account the volume requirements of the drive assembly 100 and the volume requirements of the first drive motor 11 and the second drive motor 12.

[0049] In some embodiments, refer to Figures 1 to 3 As shown, the first drive motor 11 and the second drive motor 12 are offset in the first direction X and offset in the second direction Y.

[0050] In this embodiment, the space between the first drive motor 11 and the second drive motor 12 is used to arrange the first transmission component 21 and the second transmission component 22. This allows the two drive motors and the two transmission components to be highly compact in the first direction X and the second direction Y without interfering with each other. The drive assembly 100 makes full and reasonable use of the space in the first direction X and the second direction Y, thereby improving the structural compactness of the drive assembly 100. The staggered arrangement means that the first drive motor 11 and the second drive motor 12 do not completely overlap in the first direction X and the second direction Y.

[0051] In some embodiments, refer to Figure 1 and Figure 5 As shown, the first transmission assembly 21 includes a first output shaft 27, and the second transmission assembly 22 includes a second output shaft 28. The first output shaft 27 and the second output shaft 28 are located on a first axis. The first drive motor 11 and the second drive motor 12 are distributed on both sides of the first axis along the first direction X. The projection of the line connecting the axis of the first drive motor 11, the axis of the second drive motor 12 and the first axis in the first plane is a triangle. The first plane is perpendicular to the second direction Y.

[0052] In the embodiments of this application, reference is made to Figure 5As shown, the first plane is the plane containing the first direction X and the third direction Z, where the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. By coaxially arranging the first output shaft 27 and the second output shaft 28, the drive assembly 100 can be applied to the front or rear axle of a vehicle to achieve distributed drive. Distributing the first drive motor 11 and the second drive motor 12 along the first direction X on both sides of the first axis makes the drive assembly 100 more evenly stressed. By setting the projection of the line connecting the axis of the first drive motor 11, the axis of the second drive motor 12, and the first axis in the first plane to be a triangle, the dimensions of the drive assembly 100 in the first direction X and the third direction Z are balanced, so that it does not occupy too much space in the first direction X or the third direction Z, thereby reducing the envelope size of the drive assembly 100 and improving the structural compactness.

[0053] In some embodiments, refer to Figure 3 As shown, the drive assembly 100 also includes a coupling / disconnection mechanism 30, which is connected between the first output shaft 27 of the first transmission assembly 21 and the second output shaft 28 of the second transmission assembly 22. The coupling / disconnection mechanism 30 has a separated state and an engaged state. In the separated state, the first output shaft 27 and the second output shaft 28 are disconnected. In the engaged state, the first output shaft 27 and the second output shaft 28 are connected in a transmission manner.

[0054] In this embodiment, when the disengagement mechanism 30 is in the disengaged state, the first output shaft 27 and the second output shaft 28 are disconnected. The first drive motor 11 drives the first output shaft 27 to rotate, and the second drive motor 12 drives the second output shaft 28 to rotate. The drive assembly 100 can output power through the first output shaft 27 and the second output shaft 28 respectively, making the power output of the drive assembly 100 more flexible. When the drive assembly 100 is used in a vehicle, it can independently drive different wheels, improving the flexibility of vehicle control. When the disengagement mechanism 30 is in the engaged state, the first output shaft 27 and the second output shaft 28 are connected. Any one or both drive motors can simultaneously drive the first output shaft 27 and the second output shaft 28 to rotate, enabling the drive assembly 100 to provide the vehicle with off-road capability when used in a vehicle. Thus, the configuration of the disengagement mechanism 30 allows the drive assembly 100 to have multiple power output modes to meet usage requirements.

[0055] In some embodiments, refer to Figure 3As shown, the housing 6 also includes a partition 64, a first cover plate 66, and a second cover plate 67. The partition 64 is disposed in the middle of the housing 6 and divides the interior of the housing 6 into a first accommodating cavity 61 and a second accommodating cavity 62. The first cover plate 66 is disposed on one side of the partition 64 and is used to cover the opening of the first accommodating cavity 61. The second cover plate 67 is disposed on the other side of the partition 64 and is used to cover the opening of the second accommodating cavity 62.

[0056] In this embodiment, during assembly, the drive assembly can assemble components such as the first drive motor 11 and the second transmission component 22 into the first accommodating cavity 61, and assemble components such as the second drive motor 12 and the first transmission component 21 into the second accommodating cavity 62. Finally, the first cover plate 66 covers the opening of the first accommodating cavity 61, and the second cover plate 67 covers the opening of the second accommodating cavity 62. The housing components are fewer and the installation is convenient.

[0057] In some embodiments, refer to Figure 3 As shown, the partition 64 is provided with a third accommodating cavity 63 and a third cover plate 65. The third accommodating cavity 63 is provided with a coupling and disconnection mechanism 30. In the second direction Y, one end of the third accommodating cavity 63 is provided with a bottom wall, and the other end of the third accommodating cavity 63 is provided with an opening. The third cover plate 65 is provided at the opening and is used to seal the opening. The second output shaft 28 passes through the bottom wall and is connected to the coupling and disconnection mechanism 30, and the first output shaft 27 passes through the third cover plate 65 and is connected to the coupling and disconnection mechanism 30.

[0058] In this embodiment of the application, by providing a third accommodating cavity 63 and a third cover plate 65 on the partition plate 64, the assembly of the coupling disconnection mechanism 30 and the protection of the coupling disconnection mechanism 30 can be realized.

[0059] It is understandable that the specific structure of the engagement disconnection mechanism 30 can be selected according to the usage requirements; for example, the engagement disconnection mechanism 30 can be a clutch.

[0060] In some embodiments, refer to Figure 1As shown, the first transmission assembly 21 further includes a first input shaft 23, a first intermediate shaft 25, a first input stage drive gear 211, a first input stage driven gear 212, a first output stage drive gear 213, and a first output stage driven gear 214. The first input shaft 23, the first intermediate shaft 25, and the first output shaft 27 are rotatably mounted on the housing 6. The first input shaft 23 is connected to the output shaft of the first drive motor 11 and the first input stage drive gear 211, respectively. The first intermediate shaft 25 is connected to the first input stage driven gear 212 and the first output stage drive gear 213, respectively. The first output shaft 27 is connected to the first output stage driven gear 214, wherein the first input stage drive gear 211 meshes with the first input stage driven gear 212, and the first output stage drive gear 213 meshes with the first output stage driven gear 214. When the first drive motor 11 is working, it converts electrical energy into mechanical energy that rotates the output shaft of the first drive motor 11. The output shaft of the first drive motor 11 sequentially drives the first input shaft 23, the first input stage drive gear 211, the first input stage driven gear 212, the first intermediate shaft 25, the first output stage drive gear 213, the first output stage driven gear 214, and the first output shaft 27 to rotate, and outputs power through the first output shaft 27.

[0061] In some embodiments, refer to Figure 1 As shown, the second transmission assembly 22 further includes a second input shaft 24, a second intermediate shaft 26, a second input stage drive gear 221, a second input stage driven gear 222, a second output stage drive gear 223, and a second output stage driven gear 224. The second input shaft 24, the second intermediate shaft 26, and the second output shaft 28 are rotatably mounted on the housing 6. The second input shaft 24 is connected to the output shaft of the second drive motor 12 and the second input stage drive gear 221, respectively. The second intermediate shaft 26 is connected to the second input stage driven gear 222 and the second output stage drive gear 223, respectively. The second output shaft 28 is connected to the second output stage driven gear 224. The second input stage drive gear 221 meshes with the second input stage driven gear 222, and the second output stage drive gear 223 meshes with the second output stage driven gear 224. When the second drive motor 12 is working, it converts electrical energy into mechanical energy that rotates the output shaft of the second drive motor 12. The output shaft of the second drive motor 12 sequentially drives the second input shaft 24, the second input stage drive gear 221, the second input stage driven gear 222, the second intermediate shaft 26, the second output stage drive gear 223, the second output stage driven gear 224, and the second output shaft 28 to rotate, and outputs power through the second output shaft 28.

[0062] In the drive assembly 100 of this application embodiment, the gear set of the first transmission component 21 and the gear set of the second transmission component 22 are both reduction gear sets.

[0063] This application also provides a vehicle, which includes a first wheel 200, a second wheel 300 and a drive assembly 100 of any of the above embodiments. The first wheel 200 is connected to the second transmission assembly 22, and the second wheel 300 is connected to the first transmission assembly 21.

[0064] In this embodiment, the drive assembly 100 has the advantage of a more compact structure, which is beneficial for its arrangement in the vehicle and makes the interior space layout of the vehicle more reasonable. Moreover, the first transmission component 21 is close to the second wheel 300 and the second transmission component 22 is close to the first wheel 200. The fact that the two transmission components are respectively located close to the wheels they are connected to can reduce the power transmission path of the first transmission component 21 and the second transmission component 22 and improve the transmission efficiency of the drive assembly 100.

[0065] The drive assembly 100 has its first direction (X) aligned with the vehicle's longitudinal direction, its second direction (Y) aligned with the vehicle's lateral direction, and its third direction (Z) aligned with the vehicle's vertical direction. (Refer to...) Figure 1 As shown, the first drive motor 11 is located behind the second drive motor 12. It can be understood that, referring to... Figure 2 As shown, the first drive motor 11 can also be located in front of the second drive motor 12.

[0066] The first wheel 200 and the second wheel 300 are the two front wheels of the vehicle, or the first wheel 200 and the second wheel 300 are the two rear wheels of the vehicle.

[0067] The vehicle in this embodiment of the application has the following operating modes:

[0068] In distributed drive mode, with the disconnect mechanism 30 in a disengaged state, the power from the first drive motor 11 is transmitted to the second wheel 300 via the first output shaft 27 after being reduced in speed twice by the first input stage drive gear 211, the first input stage driven gear 212, the first output stage drive gear 213, and the first output stage driven gear 214. Similarly, the power from the second drive motor 12 is transmitted to the first wheel 200 via the second output shaft 28 after being reduced in speed twice by the second input stage drive gear 221, the second input stage driven gear 222, the second output stage drive gear 223, and the second output stage driven gear 224. At this time, the first drive motor 11 independently controls the speed, torque magnitude, and direction of the second wheel 300, and the second drive motor 12 independently controls the speed, torque magnitude, and direction of the first wheel 200, enabling functions such as differential torque control, differential speed control, and U-turns.

[0069] In the off-road mode, the vehicle engages with the disconnect mechanism 30. Power from the first drive motor 11 is transmitted to the first output shaft 27 after being slowed twice by the first input stage drive gear 211, the first input stage driven gear 212, the first output stage drive gear 213, and the first output stage driven gear 214. Power from the second drive motor 12 is transmitted to the second output shaft 28 after being slowed twice by the second input stage drive gear 221, the second input stage driven gear 222, the second output stage drive gear 223, and the second output stage driven gear 224. The first output shaft 27 and the second output shaft 28 rotate synchronously, giving the vehicle a strong off-road capability.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0071] The terms “first,” “second,” “third,” “fourth,” etc., in this application (if present) are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0072] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist.
