[0029] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] Embodiment 1

[0031] As Figure 1 shown, in Embodiment 1, the power system 100 includes a hybrid power module 1, a differential 2 and a drive module 3; the output end of the hybrid power module 1 is connected to the input end of the differential 2, and the output end of the differential 2 is used to drive the left front wheel 200 of the vehicle and the right front wheel 300 of the vehicle; the drive module 3 includes a first motor 31 and a second motor 32, the first motor 31 is used to drive the left front wheel 200, and the second motor 32 is used to drive the right front wheel 300;

[0032] The hybrid power module 1 means that this module can use the engine 11 to provide power to the differential 2 and can also provide power to the differential 2 through the corresponding motors. The hybrid power module 1 can be a hybrid power system in the prior art (such as in the background art).

[0033] In this embodiment, in addition to being able to drive two wheels through the hybrid power module 1, the power system 100 can also separately drive two front wheels through the two motors of the drive module 3, thereby improving the off-road performance of the vehicle.

[0034] As Figure 2 shown, in an implementation manner of the first embodiment, the hybrid power module 1 includes an engine 11, a fifth motor 12, a sixth motor 13, a first shaft 14, a second shaft 15, and a power coupling mechanism 16; both the engine 11 and the fifth motor 12 are connected to the first shaft 14; the sixth motor 13 is connected to the second shaft 15, and the second shaft 15 is connected to the input end of the differential 2; the power coupling mechanism 16 is connected to the first shaft 14 and the second shaft 15, and the power coupling mechanism 16 has a combined state and a separated state; when the power coupling mechanism 16 is in the combined state, the torque on the first shaft 14 can be transmitted from the power coupling mechanism 16 to the second shaft 15; when the power coupling mechanism 16 is in the separated state, the torque on the first shaft 14 cannot be transmitted from the power coupling mechanism 16 to the second shaft 15.

[0035] In the first working scenario, the engine 11 and the fifth motor 12 may not work, the sixth motor 13 provides power, and the power coupling mechanism 16 is in the separated state. At this time, the driving force of the sixth motor 13 can be transmitted to the differential 2 through the second shaft 15 and drive the two wheels through the differential 2.

[0036] In the second working scenario, the engine 11 does not work, both the fifth motor 12 and the sixth motor 13 provide power, and the power coupling mechanism 16 is in the combined state. At this time, the driving forces of both the fifth motor 12 and the sixth motor 13 can be transmitted to the differential 2 through the second shaft 15 and drive the two wheels through the differential 2.

[0037] In the third working scenario, the engine 11, the fifth motor 12, and the sixth motor 13 all provide power, and the power coupling mechanism 16 is in the combined state. At this time, the driving forces of the engine 11, the fifth motor 12, and the sixth motor 13 can all be transmitted to the differential 2 through the second shaft 15 and drive the two wheels through the differential 2.

[0038] Of course, in other working scenarios, the fifth motor 12 can also be used as a generator, that is, the engine 11 drives the fifth motor 12 to rotate through the first shaft 14, and then the fifth motor 12 generates electricity. Similarly, the sixth motor 13 can also be used as a generator.

[0039] In addition, as Figure 2As shown, the first shaft 14 and the second shaft 15 are parallel and spaced apart, and they are spaced a certain distance in the radial direction of the first shaft 14. Such an arrangement is beneficial to reducing the length of the hybrid power module 1 and facilitating the installation and layout of the hybrid power module 1 on the vehicle body 600.

[0040] As Figure 1 shown, in an implementation manner of the embodiment, the hybrid power module 1 further includes a motor controller 1a. The motor controller 1a is a dual-motor controller. The motor controller 1a is electrically connected to the fifth motor 12 and the sixth motor 13 respectively. The motor controller 1a is used to control the operation of the fifth motor 12 and is used to control the operation of the sixth motor 13.

[0041] As Figure 3 shown, in an implementation manner of the first embodiment, the power coupling mechanism 16 includes a first gear set 161, a second gear set 162, a first clutch 163, a first intermediate shaft 164, and a second intermediate shaft 165. Among them, the first gear set 161 has a first driving wheel and a first driven wheel, the second gear set 162 has a second driving wheel and a second driven wheel, and the first clutch 163 has a driving end and a driven end; among them, the first driving wheel is installed on the first shaft 14 and can move synchronously with the first shaft 14; the first driven wheel and the driving end are both installed on the first intermediate shaft 164 and can both move synchronously with the first intermediate shaft 164; the driven end and the second driving wheel are both installed on the second intermediate shaft 165 and can both move synchronously with the second intermediate shaft 165; the second driven wheel is installed on the second shaft 15 and can move synchronously with the second shaft 15.

[0042] When the driving end and the driven end are combined (that is, when the first clutch 163 is in the combined state), the power coupling mechanism 16 is in the combined state. At this time, the torque on the first shaft 14 can be transmitted from the first driving wheel to the first driven wheel, and then, from the first driven wheel to the first intermediate shaft 164, and then, from the first intermediate shaft 164 to the driving end, and then from the driving end to the driven end, and then, from the driven end to the second intermediate shaft 165, and then, from the second intermediate shaft 165 to the second driving wheel, and then, from the second driving wheel to the second driven wheel, and then from the second driven wheel to the second shaft 15.

[0043] When the driving end and the driven end are separated (that is, when the first clutch 163 is in the separated state), the power coupling mechanism 16 is in the separated state, and the torque on the first intermediate shaft 164 cannot be transmitted from the first clutch 163 to the second intermediate shaft 165, thereby cutting off the torque transmission from the first shaft 14 to the second shaft 15.

[0044] Of course, in other implementation manners, the power coupling mechanism 16 can also adopt other existing designs, and this embodiment does not impose too many restrictions here.

[0045] As Figure 2 shown, in an implementation manner of the first embodiment, the hybrid power module 1 further includes a second clutch 17. The second clutch 17 is used to connect the engine 11 and the first shaft 14, and is used to control the on / off of the torque transmission between the engine 11 and the first shaft 14. When the second clutch 17 is in the engaged state, the torque of the engine 11 can be transmitted to the first shaft 14 through the second clutch 17. When the second clutch 17 is in the disengaged state, the torque of the engine 11 cannot be transmitted to the first shaft 14 through the second clutch 17.

[0046] As Figure 2 shown, in an implementation manner of the first embodiment, the hybrid power module 1 further includes a third gear set 18. The third gear set 18 includes a third driving wheel and a third driven wheel. The third driving wheel is connected to the fifth motor 12, and the third driven wheel is connected to the first shaft 14 and can move synchronously with the first shaft 14. The torque of the fifth motor 12 can be transmitted from the third gear set 18 to the first shaft 14, and at the same time, the torque on the first shaft 14 can also be transmitted from the third gear set 18 to the fifth motor 12.

[0047] As Figure 2 shown, in an implementation manner of the first embodiment, the hybrid power module 1 further includes a fourth gear set 19, a fifth gear set 20 and a third shaft 21. Among them, the fourth gear set 19 includes a fourth driving wheel and a fourth driven wheel, and the fifth gear set 20 includes a fifth driving wheel and a fifth driven wheel. The fourth driving wheel is connected to the second shaft 15 and can move synchronously with the second shaft 15. The fourth driven wheel and the fifth driving wheel are both connected to the third shaft 21 and can move synchronously with the third shaft 21. The fifth driven wheel is connected to the input end of the differential 2 and can move synchronously with the input end of the differential 2. The torque on the second shaft 15 can be transmitted to the third shaft 21 through the fourth gear set 19, and then, through the fifth gear set 20, it can be transmitted from the third shaft 21 to the input end of the differential 2.

[0048] In addition, in the radial direction of the first shaft 14, the third shaft 21 is located between the first shaft 14 and the second shaft 15.

[0049] As Figure 1 shown, the power system 100 further includes a power battery 4. The power battery 4 is electrically connected to the hybrid power module 1 and the drive module 3 respectively. Specifically, the power battery 4 can be electrically connected to the corresponding motors in both the hybrid power module 1 and the drive module 3, that is, the power battery 4 can be electrically connected to the first motor 31, the second motor 32, the fifth motor 12 and the sixth motor 13.

[0050] In an implementation manner of Embodiment 1, when the hybrid power module 1 includes the engine 11 and the fifth motor 12, the engine 11 is connected to the fifth motor 12, and the fifth motor 12 is electrically connected to at least one of the first motor 31 and the second motor 32.

[0051] During operation, both the first motor 31 and the second motor 32 can also be used as generators. For example, in the braking and deceleration condition, the first motor 31 and the second motor 32 can be used for power generation, and the electricity generated by the two can charge the power battery 4. When the power battery 4 is fully charged, the electricity generated by the one or two of them connected to the fifth motor 12 can drive the fifth motor 12, so that the fifth motor 12 drives the engine 11 to idle, which can consume the energy generated by the electric braking. In this way, it can not only prevent the motor (i.e., the first motor 31 and / or the second motor 32) from overheating and demagnetizing, but also avoid the thermal failure caused by the long-term braking of the brake disc of the braking system.

[0052] Preferably, the fifth motor 12 is electrically connected to the first motor 31 and the second motor 32 respectively.

[0053] As Figure 1 shown, in an implementation manner of Embodiment 1, both the first motor 31 and the second motor 32 are in-wheel motors. The first motor 31 is suitable for being installed in the left front wheel 200, and the second motor 32 is suitable for being installed in the right front wheel 300; alternatively, the first motor 31 and the second motor 32 are located between the left front wheel 200 and the right front wheel 300, wherein the first motor 31 and the second motor 32 can be installed in the front engine compartment.

[0054] Among them, when the first motor 31 and the second motor 32 are in-wheel motors, the first motor 31 can be installed in the left front wheel 200, and the second motor 32 can be installed in the right front wheel 300, so as to reduce the space occupied by the drive module 3 in the front engine compartment, so that the hybrid power module 1 can have a larger installation space in the front engine compartment, which is conducive to the selection and layout of the hybrid power module 1.

[0055] When the first motor 31 and the second motor 32 are located between the left front wheel 200 and the right front wheel 300, it is convenient to design the cooling systems for the two.

[0056] As Figure 1 shown, in an implementation manner of Embodiment 1, the drive module 3 further includes a first controller 35 and a second controller 36; wherein, the first controller 35 is electrically connected to the first motor 31 and is used to control the operation of the first motor 31; the second controller 36 is electrically connected to the second motor 32 and is used to control the operation of the second motor 32.

[0057] When the first motor 31 and the second motor 32 are in-wheel motors, and the first motor 31 can be installed in the left front wheel 200 and the second motor 32 can be installed in the right front wheel 300, the first controller 35 and the second controller 36 can be arranged separately, and the first controller 35 is installed in the left front wheel 200 and the second controller 36 is installed in the right front wheel 300. Such an arrangement can further reduce the space occupied by the drive module 3 in the front engine compartment.

[0058] It should be understood that in other embodiments, the first controller 35 and the second controller 36 can also be integrated to form a control unit. For example, the two are integrated in a housing or on a circuit board. At this time, the control unit can be installed in the front engine compartment. Of course, in other embodiments, when the first controller 35 and the second controller 36 are arranged separately, both of them can also be arranged in the front engine compartment.

[0059] As Figure 1 shown, in an embodiment of Embodiment 1, the power system further includes a first drive half shaft 51 and a second drive half shaft 52. Among them, the first drive half shaft 51 is connected to the left front wheel 200, the second drive half shaft 52 is connected to the right front wheel 300, and both the first drive half shaft 51 and the second drive half shaft 52 are connected to the output end of the differential 2. The torque of the differential 2 can be transmitted to the left front wheel 200 through the first drive half shaft 51 and can be transmitted to the right front wheel 300 through the second drive half shaft 52.

[0060] Embodiment 2

[0061] As Figure 4 shown, the difference between Embodiment 2 and Embodiment 1 is that: in addition to the first motor 31 and the second motor 32, the drive module 3 further includes a third motor 33 and a fourth motor 34. Among them, the third motor 33 is used to drive the left rear wheel 400, and the fourth motor 34 is used to drive the right rear wheel 500.

[0062] In an embodiment of Embodiment 2, both the third motor 33 and the fourth motor 34 are in-wheel motors. The third motor 33 is suitable for being installed in the left rear wheel 400, and the fourth motor 34 is suitable for being installed in the right rear wheel 500; or, the third motor 33 and the fourth motor 34 are located between the left rear wheel 400 and the right rear wheel 500, and both the third motor 33 and the fourth motor 34 are installed at the rear of the vehicle body.

[0063] Among them, both the third motor 33 and the fourth motor 34 being installed at the rear of the vehicle body can mean that: both the third motor 33 and the fourth motor 34 are installed on the vehicle body, and both the third motor 33 and the fourth motor 34 are located behind the front wheels of the vehicle. As Figure 3 shown, in an embodiment, the third motor 33 and the fourth motor 34 can be arranged behind the power battery 4.

[0064] In an implementation manner of the second embodiment, when the hybrid power module 1 includes the engine 11 and the fifth motor 12, the engine 11 is connected to the fifth motor 12, and the fifth motor 12 is electrically connected to at least one of the first motor 31, the second motor 32, the third motor 33, and the fourth motor 34.

[0065] During operation, the first motor 31, the second motor 32, the third motor 33, and the fourth motor 34 can also be used as generators. For example, in the braking and deceleration condition, the first motor 31, the second motor 32, the third motor 33, and the fourth motor 34 can be used for power generation, and the electricity generated by the four motors can charge the power battery 4. When the power battery 4 is fully charged, the electricity generated by the one or two motors connected to the fifth motor 12 among the four motors can drive the fifth motor 12, so that the fifth motor 12 drives the engine 11 to idle, which can consume the energy generated by the electric braking. This can not only prevent the motor from overheating and demagnetization, but also avoid the thermal failure caused by the long-term braking of the brake disc of the braking system.

[0066] Preferably, the fifth motor 12 is electrically connected to the first motor 31, the second motor 32, the third motor 33, and the fourth motor 34 respectively.

[0067] In an implementation manner of the second embodiment, the drive module 3 further includes a third controller 37. The third controller 37 is a dual-motor controller, and the third controller 37 is electrically connected to the third motor 33 and the fourth motor 34 respectively. Among them, the third controller 37 is used to control the operation of the third motor 33, and the third controller 37 is also used to control the operation of the fourth motor 34. In addition, the third controller 37 can be installed on the vehicle body 600. Among them, the dual-motor controller is equivalent to the above control unit, that is, the controllers for controlling the third motor 33 and the fourth motor 34 are integrated together.

[0068] Of course, in other scenarios, the controllers for controlling the third motor 33 and the fourth motor 34 can also be separately arranged. For example, as shown in Figure 5 shown, the drive module 3 includes a fourth controller 38 and a fifth controller 39. Among them, the fourth controller 38 is electrically connected to the third motor 33 and is used to control the operation of the third motor 33; the fifth controller 39 is electrically connected to the fourth motor 34 and is used to control the operation of the fourth motor 34.

[0069] In an implementation manner of the second embodiment, when both the third motor 33 and the fourth motor 34 are in-wheel motors, the third motor 33 is installed in the left rear wheel 400, and the fourth motor 34 is installed in the right rear wheel 500, the fourth controller 38 can be arranged in the left rear wheel 400, and the fifth controller 39 can be arranged in the right rear wheel 500 (refer toFigure 5 )。

[0070] As Figure 4 shown, in an implementation manner of the second embodiment, when the third motor 33 and the fourth motor 34 are located between the left rear wheel 400 and the right rear wheel 500, the hybrid power module 1 further includes a third drive half shaft 53 and a fourth drive half shaft 54. Among them, the third drive half shaft 53 is connected to the left rear wheel 400, the fourth drive half shaft 54 is connected to the right rear wheel 500, the third drive half shaft 53 is connected to the third motor 33, the fourth drive half shaft 54 is connected to the fourth, the torque of the third motor 33 can be transmitted to the left rear wheel 400 through the third drive half shaft 53, and the torque of the fourth motor 34 can be transmitted to the right rear wheel 500 through the fourth drive half shaft 54.

[0071] As Figure 4 shown, in an implementation manner of the second embodiment, when the third motor 33 and the fourth motor 34 are located between the left rear wheel 400 and the right rear wheel 500, the drive module 3 further includes a first transmission mechanism 3a and a second transmission mechanism 3b. The third motor 33 drives the left rear wheel 400 through the first transmission mechanism 3a, and the fourth motor 34 drives the right rear wheel 500 through the second transmission mechanism 3b. Among them, both the first transmission mechanism 3a and the second transmission mechanism 3b can be speed reducers.

[0072] In addition, other settings in the second embodiment can be the same as those in the first embodiment.

[0073] In the second embodiment, in addition to being able to drive two wheels through the hybrid power module 1, the power system 100 can also separately drive the four wheels through the four motors of the drive module 3, thereby improving the off-road performance of the vehicle.

[0074] In this embodiment, the vehicle can implement the following working modes:

[0075]

[0076]

[0077] Embodiment Three

[0078] As Figure 5 and Figure 6 shown, the difference between the third embodiment and the second embodiment is that: in the third embodiment, the first motor 31, the second motor 32, the first controller, and the second controller in the second embodiment are not provided in the drive module 3.

[0079] In addition, other settings in the third embodiment can be the same as those in the second embodiment.

[0080] In the third embodiment, in addition to being able to drive two wheels through the hybrid power module 1, the power system 100 can also separately drive two rear wheels through two motors of the drive module 3, thereby improving the off-road performance of the vehicle.

[0081] The embodiment of the present utility model also provides a vehicle, which is equipped with the power system 100 described in any of the above embodiments, and the power system 100 is connected to the vehicle body 600.
