[0037] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-9 The power system 100 according to an embodiment of the present utility model is described. The power system 100 includes: a drive motor 10 and a transmission device 11.

[0038] like Figure 1 , Figure 4 and Figure 7 As shown, the drive motor 10 is adapted to be connected to the first wheel 80 and the second wheel 81 via the transmission device 11. The transmission device 11 includes a first transmission state and a second transmission state. In the first transmission state, the drive motor 10 is adapted to drive the first wheel 80 and the second wheel 81 to rotate in the same direction via the transmission device 11. In the second transmission state, the drive motor 10 is adapted to drive the first wheel 80 to rotate in a first direction via the transmission device 11, and the drive motor 10 is adapted to drive the second wheel 81 to rotate in a second direction via the transmission device 11. The first direction and the second direction are different. One of the first direction and the second direction can be a clockwise direction, and the other of the first direction and the second direction can be a counterclockwise direction.

[0039] The drive motor 10 is adapted to convert electrical energy into mechanical energy and output power. The transmission device 11 is disposed between the drive motor 10 and the first wheel 80 and the second wheel 81 to transmit the power output by the drive motor 10 to the first wheel 80 and the second wheel 81, respectively. When the transmission device 11 is in the first transmission state, the power transmitted by the transmission device 11 to the first wheel 80 and the second wheel 81 can cause the first wheel 80 and the second wheel 81 to rotate together in a first direction or a second direction. When the transmission device 11 is in the second transmission state, the power transmitted by the transmission device 11 to the first wheel 80 can cause the first wheel 80 to rotate in the first direction, and the power transmitted by the transmission device 11 to the second wheel 81 can cause the second wheel 81 to rotate in the second direction.

[0040] According to the power system 100 of this utility model embodiment, by switching between the first transmission state and the second transmission state through the transmission device 11, the drive motor 10 can simultaneously drive the first wheel 80 and the second wheel 81 to rotate in the same direction, or the drive motor 10 can simultaneously drive the first wheel 80 and the second wheel 81 to rotate in opposite directions. This improves the functionality of the drive motor 10, enhances the flexibility and reliability of the power system 100, enables the vehicle to adapt to different driving needs, and increases the vehicle's handling and adaptability.

[0041] According to some embodiments of this utility model, such as Figures 1-9 As shown, the transmission device 11 includes a clutch 15, which has a first engaged state and a second engaged state. In the first transmission state, the clutch 15 is in the first engaged state, and the drive motor 10 is adapted through the transmission device 11 to drive the first wheel 80 and the second wheel 81 to rotate in a first direction or in a second direction. In the second transmission state, the clutch 15 is in the second engaged state, and the drive motor 10 is adapted through the transmission device 11 to drive one of the first wheel 80 and the second wheel 81 to rotate in the first direction, and the drive motor 10 is adapted through the transmission device 11 to drive the other of the first wheel 80 and the second wheel 81 to rotate in the second direction.

[0042] Switching between the first and second engaged states of the clutch 15 alters the power transmission path between the drive motor 10 and the first and second wheels 80 and 81, thereby changing the direction of power transmitted from the transmission device 11 to the first and second wheels 80 and 81. When the transmission device 11 is in the first transmission state, the clutch 15 is in the first engaged state, and the power transmitted from the transmission device 11 to the first and second wheels 80 is in the same direction, causing the first and second wheels 80 and 81 to rotate together in either the first or second direction. When the transmission device 11 is in the second transmission state, the clutch 15 is in the second engaged state, and the power transmitted from the transmission device 11 to the first and second wheels 81 is in opposite directions. For example, the drive motor 10 drives the first wheel 80 to rotate in the first direction via the transmission device 11, and the drive motor 10 also drives the second wheel 81 to rotate in the second direction via the transmission device 11. Optionally, the drive motor 10 drives the first wheel 80 to rotate in the second direction via the transmission device 11, and the drive motor 10 also drives the second wheel 81 to rotate in the first direction via the transmission device 11.

[0043] Thus, by switching between the first transmission state and the second transmission state through the transmission device 11, the clutch 15 switches between the first engagement state and the second engagement state, changing the direction of power transmitted by the transmission device 11 to the first wheel 80 and the second wheel 81 according to different driving needs of the vehicle, further enhancing the flexibility and controllability of the power system 100, while improving the vehicle's handling and adaptability, making it easier to cope with complex driving environments.

[0044] According to some embodiments of this utility model, such as Figures 1-9 As shown, the transmission device 11 further includes: a first transmission device 20 and a second transmission device 30. The drive motor 10 is adapted to be connected to the first wheel 80 via the first transmission device 20, and the first transmission device 20 includes a clutch 15. The drive motor 10 is adapted to be connected to the second wheel 81 via the second transmission device 30.

[0045] The first transmission device 20 can transmit the power output by the drive motor 10 to the first wheel 80, and the second transmission device 30 can transmit the power output by the drive motor 10 to the second wheel 81. When the clutch 15 switches from the first engagement state to the second engagement state, the transmission path of the power between the drive motor 10 and the first wheel 80 changes, so that the direction of the power transmitted from the first transmission device 20 to the first wheel 80 is opposite to the direction of the power transmitted from the second transmission device 30 to the second wheel 81.

[0046] According to some embodiments of this utility model, such as Figures 1-6 As shown, the drive motor 10 includes a first output gear 12 and a second output gear 13; the first transmission device 20 also includes a first transmission sub-gear 21 and a second transmission sub-gear 22, the first transmission sub-gear 21 being drivenly connected to the first output gear 12, and the second transmission sub-gear 22 being drivenly connected to the second output gear 13; a clutch 15 is disposed between the first transmission sub-gear 21 and the second transmission sub-gear 22; when the clutch 15 is in a first engaged state, the clutch 15 is engaged with the second transmission sub-gear 22 and disengaged from the first transmission gear 21, so that the second output gear 13 is adapted to be drivenly connected to the first wheel 80 through the second transmission sub-gear 22; when the clutch 15 is in a second engaged state, the clutch 15 is engaged with the first transmission gear 21 and disengaged from the second transmission gear 22, so that the first output gear 12 is adapted to be drivenly connected to the first wheel 80 through the first transmission gear 21; the second transmission device 30 includes a second transmission gear 31, and the second output gear 13 is adapted to be drivenly connected to the second wheel 81 through the second transmission gear 31.

[0047] In this embodiment, the first output gear 12 and the second output gear 13 are coaxially driven, and the power output by the drive motor 10 is output by the first output gear 12 and the second output gear 13 respectively. When the clutch 15 is in the first engaged state, the clutch 15 meshes with the second transmission sub-gear 22, and the second transmission sub-gear 22 transmits the power output by the second output gear 13 to the first transmission sub-gear 21. Subsequently, the first transmission sub-gear 21 transmits the power to the first wheel 80. At this time, the first output gear 12 and the first transmission sub-gear 21 idle. When the clutch 15 is in the second engaged state, the clutch 15 meshes with the first transmission sub-gear 21, and the first transmission sub-gear 21 transmits the power output by the first output gear 12 to the first wheel 80.

[0048] According to some embodiments of this utility model, such as Figures 1-3 As shown, the transmission device 11 further includes: a first intermediate transmission device 40, which includes a first intermediate gear 41, a first intermediate sub-gear 42, and a second intermediate sub-gear 43. The first intermediate gear 41 meshes with the second output gear 13, the first intermediate sub-gear 42 meshes with the second transmission sub-gear 22, and the second intermediate sub-gear 43 meshes with the second transmission gear 31.

[0049] In this embodiment, the first intermediate gear 41, the first intermediate sub-gear 42, and the second intermediate sub-gear 43 are coaxially driven, meaning that the rotation directions of the first intermediate gear 41, the first intermediate sub-gear 42, and the second intermediate sub-gear 43 are the same. Combined with... Figure 2 Taking the clockwise rotation of the first output gear 12 and the second output gear 13 as an example, when the first wheel 80 and the second wheel 81 need to rotate in the same direction, the clutch 15 is engaged with the second transmission sub-gear 22. At this time, the first output gear 12 and the first transmission sub-gear 21 idle. The power output by the second output gear 13 is transmitted to the first intermediate gear 41, causing the first intermediate gear 41 to rotate counterclockwise. The first intermediate gear 41 transmits power to the first intermediate sub-gear 42 and the second intermediate sub-gear 43 respectively. The first intermediate sub-gear 42 then transmits power to the second transmission sub-gear 22, causing the second transmission sub-gear 22 to rotate clockwise. The second transmission sub-gear 22 drives the first wheel 80 to rotate clockwise. The second intermediate gear 43 transmits power to the second transmission gear 31, causing the second transmission gear 31 to rotate clockwise. The second transmission gear 31 drives the second wheel 81 to rotate clockwise, thereby realizing the clockwise rotation of the first wheel 80 and the second wheel 81.

[0050] Combination Figure 3When the first wheel 80 and the second wheel 81 need to rotate in opposite directions, the clutch 15 engages with the first transmission sub-gear 21. At this time, the power output by the first output gear 12 is transmitted to the first transmission sub-gear 21, causing the first transmission sub-gear 21 to rotate counterclockwise. The first transmission sub-gear 21 drives the first wheel 80 to rotate counterclockwise. The power output by the second output gear 13 is transmitted to the first intermediate gear 41, causing the first intermediate gear 41 to drive the second intermediate sub-gear 43 to rotate counterclockwise. The second intermediate sub-gear 43 transmits the power to the second transmission gear 31, causing the second transmission gear 31 to rotate clockwise. The second transmission gear 31 drives the second wheel 81 to rotate clockwise, thereby realizing the reverse rotation of the first wheel 80 and the second wheel 81.

[0051] According to some embodiments of this utility model, such as Figures 4-6 As shown, the transmission device 11 further includes: a second intermediate transmission device 50, which includes a second intermediate gear 51 and a third intermediate gear 52. The second intermediate gear 51 meshes with the second output gear 13, and the second transmission sub-gear 22 and the second transmission gear 31 both mesh with the third intermediate gear 52.

[0052] In this embodiment, the second intermediate gear 51 and the third intermediate gear 52 are coaxially driven. Figure 5 When the first wheel 80 and the second wheel 81 need to rotate in the same direction, the clutch 15 engages with the second transmission gear 22. At this time, the first output gear 12 and the first transmission gear 21 idle. The power output by the second output gear 13 is transmitted to the second intermediate gear 51, causing the second intermediate gear 51 to rotate counterclockwise. The second intermediate gear 51 drives the third intermediate gear 52 to rotate counterclockwise. The third intermediate gear 52 transmits power to the second transmission gear 22 and the second transmission gear 31, causing both the second transmission gear 22 and the second transmission gear 31 to rotate clockwise. The second transmission gear 22 drives the first wheel 80 to rotate clockwise, and the second transmission gear 31 drives the second wheel 81 to rotate clockwise, thereby achieving the rotation of the first wheel 80 and the second wheel 81 in the same direction.

[0053] Combination Figure 6When the first wheel 80 and the second wheel 81 need to rotate in opposite directions, the clutch 15 engages with the first transmission sub-gear 21. At this time, the power output by the first output gear 12 is transmitted to the first transmission sub-gear 21, causing the first transmission sub-gear 21 to rotate counterclockwise. The first transmission sub-gear 21 drives the first wheel 80 to rotate counterclockwise. The power output by the second output gear 13 is transmitted to the second intermediate gear 51, causing the second intermediate gear 51 to rotate counterclockwise. The second intermediate gear 51 drives the third intermediate gear 52 to rotate counterclockwise. The third intermediate gear 52 transmits the power to the second transmission gear 31, causing the second transmission gear 31 to rotate clockwise. The second transmission gear 31 drives the second wheel 81 to rotate clockwise, thereby realizing the reverse rotation of the first wheel 80 and the second wheel 81.

[0054] According to some embodiments of this utility model, such as Figures 7-9 As shown, the drive motor 10 includes a third output gear 14; the first transmission device 20 includes a first transmission gear set 23 and a second transmission gear set 24. The first transmission gear set 23 includes a first sub-transmission gear 231 and a second sub-transmission gear 232 that mesh with each other. The second transmission gear set 24 includes a third sub-transmission gear 241, a fourth sub-transmission gear 242 and a fifth sub-transmission gear 243 that mesh in sequence. The first sub-transmission gear 231 and the third sub-transmission gear 241 are adapted to be connected to the third output gear 14 via a clutch 15. The second sub-transmission gear 232 and the fifth sub-transmission gear 243 are adapted to be connected to the first wheel 80. The second transmission device 30 includes a third transmission gear 32 and a fourth transmission gear 33 that mesh with each other. The third transmission gear 32 is connected to the third output gear 14, and the fourth transmission gear 33 is adapted to be connected to the second wheel 81.

[0055] In this embodiment, the transmission device 11 further includes a fourth intermediate gear 60, which is coaxially driven with the first sub-transmission gear 231, the third sub-transmission gear 241, and the third transmission gear 32. Taking the clockwise rotation of the third output gear 14 as an example, combined with... Figure 8When the first wheel 80 and the second wheel 81 need to rotate in the same direction, the clutch 15 engages with the first sub-drive gear 231. At this time, the power output by the third output gear 14 is transmitted to the fourth intermediate gear 60, causing the fourth intermediate gear 60 to rotate counterclockwise. The fourth intermediate gear 60 drives the first sub-drive gear 231 and the third drive gear 32 to rotate counterclockwise. The third drive gear 32 transmits power to the fourth drive gear 33, causing the fourth drive gear 33 to rotate clockwise. The fourth drive gear 33 drives the second wheel 81 to rotate clockwise. The first sub-drive gear 231 transmits power to the second sub-drive gear 232, causing the second sub-drive gear 232 to rotate clockwise. The second drive gear 232 drives the first wheel 80 to rotate clockwise, thus achieving the rotation of the first wheel 80 and the second wheel 81 in the same direction.

[0056] Combination Figure 9 When the first wheel 80 and the second wheel 81 need to rotate in opposite directions, the clutch 15 engages with the third sub-drive gear 241. At this time, the first sub-drive gear 231 and the second sub-drive gear 232 idle. The power output by the third output gear 14 is transmitted to the fourth intermediate gear 60, causing the fourth intermediate gear 60 to rotate counterclockwise. The fourth intermediate gear 60 drives the third sub-drive gear 241 and the third drive gear 32 to rotate counterclockwise. The third drive gear 32 transmits power to the fourth drive gear 33, causing... The fourth transmission gear 33 rotates clockwise, driving the second wheel 81 to rotate clockwise; the third sub-transmission gear 241 transmits power to the fourth sub-transmission gear 242, causing the fourth sub-transmission gear 242 to rotate clockwise, and the fourth sub-transmission gear 242 transmits power to the fifth sub-transmission gear 243, causing the fifth sub-transmission gear 243 to rotate counterclockwise, driving the first wheel 80 to rotate counterclockwise, thus realizing the opposite rotation of the first wheel 80 and the second wheel 81.

[0057] According to some embodiments of this utility model, such as Figures 1-9 As shown, the power system 100 also includes at least one torque vector manager 70, which is disposed between at least one of the first wheel 80 and the second wheel 81 and the transmission 11.

[0058] In this embodiment, a torque vector manager 70 is provided between the first wheel 80 and the second wheel 81 and the conventional device, respectively. The torque vector manager 70 is adapted to distribute the torque transmitted by the drive motor 10 to the first wheel 80 and the second wheel 81, such that the torque range of the first wheel 80 and the second wheel 81 is 0-2600 Nm. The torque vector manager 70 includes a first torque vector manager 71 and a second torque vector manager 72.

[0059] Combination Figure 1 and Figure 4 A first torque vector manager 71 is provided between the first transmission gear 21 and the first wheel 80. The first torque vector manager 71 can distribute the torque transmitted from the drive motor 10 to the first wheel 80. A second torque vector manager 72 is provided between the second transmission gear 31 and the second wheel 81. The first torque vector manager 71 can distribute the torque transmitted from the drive motor 10 to the second wheel 81.

[0060] Optionally, combined Figure 7 A first torque vector manager 71 is provided between the fifth sub-transmission gear 243 and the first wheel 80, and a second torque vector manager 72 is provided between the fourth transmission gear 33 and the second wheel 81.

[0061] Therefore, by placing the torque vector manager 70 between at least one of the first wheel 80 and the second wheel 81 and the transmission device 11, the torque of the first wheel 80 and the second wheel 81 can be reasonably distributed according to different driving needs of the vehicle, thereby improving the accuracy of the power system 100, improving the handling and adaptability of the vehicle, and at the same time, improving the stability and safety of the vehicle during driving.

[0062] In this embodiment, when the clutch 15 is not engaged with either the first transmission sub-gear 21 or the second transmission sub-gear 22, or when the clutch 15 is not engaged with either the first sub-transmission gear 231 or the third sub-transmission gear 241, the drive motor 10 only drives the second wheel 81 to rotate, and the second torque vector manager 72 distributes the torque transmitted from the drive motor 10 to the second wheel 81.

[0063] Optionally, when the torque vector manager 70 is disengaged from both the first wheel 80 and the second wheel 81, the drive motor 10 does not drive the first wheel 80 and the second wheel 81 to rotate, and the vehicle is in a gliding state.

[0064] The vehicle according to a second aspect of the present invention includes the power system 100 in the above embodiments.

[0065] By switching between the first transmission state and the second transmission state in the power system 100, the drive motor 10 can simultaneously drive the first wheel 80 and the second wheel 81 to rotate in the same direction or simultaneously drive the first wheel 80 and the second wheel 81 to rotate in opposite directions. At the same time, by distributing the torque transmitted from the drive motor 10 to the first wheel 80 and the second wheel 81 through the torque vector manager 70, the vehicle's flexibility and adaptability can be improved, and the stability and reliability of the vehicle during driving can be enhanced.

[0066] According to some embodiments of the present invention, the first wheel 80 and the second wheel 81 of the vehicle are the rear wheels of the vehicle.

[0067] In this embodiment, by switching between the first transmission state and the second transmission state through the transmission device 11, the steering of the rear wheels of the vehicle is controlled. At the same time, in conjunction with the torque vector manager 70 and the independent drive of the front wheels, applications such as turning the vehicle on the spot and reducing the turning radius can be better realized, effectively improving the flexibility and accuracy of vehicle steering.
