Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0081] In the description of this invention, "first feature" and "second feature" may include one or more of the features.

[0082] In the description of this invention, "a plurality of" means two or more, and "several" means one or more.

[0083] The hybrid power system 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0084] like Figures 1-27 As shown, the hybrid power system 1 according to an embodiment of the present invention includes a first motor 100, an engine 200, an input shaft 300, an output shaft 400, and a clutch 600.

[0085] The first motor 100 is driven by the input shaft 300, and the engine 200 is selectively driven by the input shaft 300. The output shaft 400 is used to output power to the wheels. The clutch 600 is located between the input shaft 300 and the output shaft 400 so that the input shaft 300 is selectively driven by the output shaft 400.

[0086] In this embodiment of the invention, both the engine 200 and the first motor 100 can be arranged longitudinally.

[0087] The selective connection of engine 200 to input shaft 300 means that engine 200 can be connected to input shaft 300, or engine 200 can disconnect power transmission from input shaft 300.

[0088] In addition, a torsional damper 220 can be provided between the engine shaft 210 and the input shaft 300 of the engine 200 to prevent the output torque of the engine 200 from being too large, so that the engine 200 can output power stably.

[0089] For example, the output shaft 400 can be used to output power to the front wheels 920 of the vehicle, that is, the first motor 100 and the engine 200 are used to drive the front wheels 920 of the vehicle in a combined manner.

[0090] According to the hybrid power system 1 of the present invention, by driving the first motor 100 to the input shaft 300 and selectively driving the engine 200 to the input shaft 300, when the engine 200 is disconnected from the input shaft 300, the first motor 100 can drive the front wheels 920 of the vehicle to rotate alone; or, when the engine 200 and the input shaft 300 are driven together, the engine 200 can drive the front wheels 920 of the vehicle to rotate alone; or the engine 200 and the first motor 100 can be used together to drive the front wheels 920 of the vehicle to rotate, thereby driving the vehicle.

[0091] Moreover, in the front drive section of the hybrid system 1, only one first motor 100 needs to be set. The first motor 100 can act as a drive motor under corresponding operating conditions and can also act as a generator under specific operating conditions. This setting can simplify the structure of the hybrid system 1, reduce the number of motors and related gears in the hybrid system 1, thereby reducing the cost of the hybrid system 1 and making the structure of the hybrid system 1 more compact.

[0092] In addition, the clutch 600 is located between the input shaft 300 and the output shaft 400 so that the input shaft 300 can be selectively connected to the output shaft 400. In this way, the clutch 600 can be used to select whether to transmit power to the input shaft 300 and the output shaft 400 or to disconnect the power transmission, thereby controlling the power output of the engine 200 and the first motor 100. Alternatively, the input shaft can also use the clutch 600 to transmit power to the output shaft 400 through different gear pairs, thereby enabling the vehicle to be driven in different gears.

[0093] Furthermore, by setting a clutch 600, for example, the clutch 600 can be set between shafts to control the power transmission and interruption between shafts, or the clutch 600 can be set in correspondence with a gear pair. When a clutch 600 is engaged with a corresponding gear pair, the input shaft 300 can transmit power to the output shaft 400 through the gear pair. That is, the clutch 600 can control the power transmission and interruption between the shaft and the gear. This setting helps to simplify the switching of the power transmission path of the hybrid power system 1, and facilitates the hybrid power system 1 to switch to different gears for power output. Moreover, the clutch 600 occupies less space and has a simpler structure, which helps to make the structure of the hybrid power system 1 more compact and facilitates the layout of the hybrid power system 1.

[0094] Thus, the hybrid power system 1 according to the embodiments of the present invention has the advantages of simple structure, compact structure, small space occupation and easy switching of drive path.

[0095] In some embodiments of the present invention, such as Figure 1As shown, the transmission mechanism 500 has a gear pair, which is located between the input shaft 300 and the output shaft 400. The clutch 600 is located on the input shaft 300 and / or the output shaft 400, and the clutch 600 connects or disconnects the input shaft 300 and / or the output shaft 400 from the gear pair, so that the input shaft 300 is selectively connected to the output shaft 400 through the gear pair.

[0096] Therefore, when the hybrid system 1 needs to transmit power through the input shaft 300 and the output shaft 400, the clutch 600 can be engaged, so that the input shaft 300 can transmit power to the output shaft 400 through the gear pair to drive the vehicle.

[0097] Alternatively, there can be multiple gear pairs. In this way, the input shaft 300 can be driven to the output shaft 400 through different gear pairs via the clutch 600, thereby enabling the vehicle to be driven in different gears.

[0098] In some specific embodiments of the present invention, such as Figure 2 , Figures 17-19 As shown, the hybrid power system 1 also includes a second motor 110 and a power battery 120.

[0099] The second motor 110 is used to drive one of the front wheels 920 and the rear wheels 930 of the vehicle, and the engine 200 and the first motor 100 are used to drive the other of the front wheels 920 and the rear wheels 930 of the vehicle. The power battery 120 is located between the first motor 100 and the second motor 110 and is electrically connected to the first motor 100 and the second motor 110 respectively, so that the power battery 120 can supply power to the first motor 100 and the second motor 110 respectively.

[0100] For example, engine 200 and first motor 100 can be used to drive the front wheels 920 of the vehicle, and second engine 200 can be used to drive the rear wheels 930 of the vehicle. Thus, hybrid system 1 can realize pure electric front drive, hybrid front drive, engine direct drive front drive, pure electric rear drive, pure electric four-wheel drive, and hybrid four-wheel drive.

[0101] By adding a second motor 110 to drive the rear wheel 930, when the power battery 120 has a low charge, the rear wheel 930 can be driven by the second motor 110, and the first motor 100 can generate electricity. Alternatively, the rear wheel 930 can be driven by the second motor 110, and the first motor 100 can generate electricity while driving the front wheel 920. This avoids the problem of significant power performance degradation when the power battery 120 has a low charge, and the driving force of the hybrid system 1 is more sufficient.

[0102] In addition, the hybrid power system 1 may also be provided with multiple motor controllers 130, and the multiple motor controllers 130 are respectively connected to the first motor 100 and the second motor 110 in a one-to-one correspondence, so as to control the operation of the first motor 100 and the second motor 110 through the motor controllers 130.

[0103] In addition, the power output from the second motor 110 can also be transmitted to the wheels through the reducer and differential 900.

[0104] In some specific embodiments of the present invention, such as Figure 2 , Figures 17-19 As shown, the multiple gear pairs include a first gear pair 520 and a second gear pair 530. The first gear pair 520 and the second gear pair 530 have different transmission ratios.

[0105] Specifically, the clutch 600 is switchably connected to one of the first gear pair 520 and the second gear pair 530 so that the input shaft 300 is selectively connected to the output shaft 400 via one of the first gear pair 520 and the second gear pair 530.

[0106] Wherein, the clutch 600 connects or disconnects the input shaft 300 and / or the output shaft (400) from the first gear pair 520 or the second gear pair 530. This means that the input shaft 300 or the output shaft 400 can be connected to the first gear pair 520 through the clutch 600, at which time the input shaft 300 can transmit power to the output shaft 400 through the first gear pair 520; or, the input shaft 300 or the output shaft 400 can be connected to the second gear pair 530 through the clutch 600, at which time the input shaft 300 can transmit power to the output shaft 400 through the second gear pair 530.

[0107] Therefore, by switching the state of clutch 600, the power output path of hybrid system 1 can be switched. That is, power can be transmitted to output shaft 400 through first gear pair or second gear pair 530, making power switching more convenient.

[0108] In some specific embodiments of the present invention, such as Figure 2 , Figure 17 and Figure 18 As shown, there are multiple clutches 600, including a first clutch 610 and a second clutch 620. The first clutch 610 connects or disconnects the input shaft 300 and / or the output shaft 400 from the first gear pair 520, and the second clutch 620 connects or disconnects the input shaft 300 and / or the output shaft 400 from the second gear pair 530.

[0109] The first clutch 610 connects or disconnects the input shaft 300 and / or the output shaft 400 from the first gear pair 520, meaning that the input shaft 300 can be controlled to output power to the output shaft 400 through the first gear pair 520 by engaging the first clutch 610.

[0110] The second clutch 620 connects or disconnects the input shaft 300 and / or the output shaft 400 from the second gear pair 530. This means that by engaging the second clutch 620, the input shaft 300 can be controlled to output power to the output shaft 400 through the second gear pair 530.

[0111] In other words, clutch 600 is a single clutch. When the hybrid power system 1 needs to drive the front wheel 920 to rotate, one of the first clutch 610 and the second clutch 620 can be engaged, while the other of the first clutch 610 and the second clutch 620 can be disengaged. This configuration makes the structure of clutch 600 simpler and occupies less space, facilitating its arrangement and further simplifying the structure of the hybrid power system 1, making the structure of the hybrid power system 1 more compact and simplifying the switching of the output path of the hybrid power system 1.

[0112] In some specific embodiments of the present invention, such as Figure 2 , Figure 17 and Figure 18 As shown, the first gear pair 520 includes a first gear 521 and a second gear 522 that mesh with each other. The first clutch 610 connects or disconnects the input shaft 300 or the output shaft 400 with the first gear 521, or connects or disconnects the input shaft 300 or the output shaft 400 with the second gear 522. The second gear pair 530 includes a third gear 531 and a fourth gear 532 that mesh with each other. The second clutch 620 connects or disconnects the input shaft 300 or the output shaft 400 with the third gear 531, or connects or disconnects the input shaft 300 or the output shaft 400 with the fourth gear 532.

[0113] Specifically, the first clutch 610 connects or disconnects the input shaft 300 or output shaft 400 from the first gear 521, or connects or disconnects the input shaft 300 or output shaft 400 from the second gear 522. This means that the first clutch 610 can control the power transmission at the first gear 521 or the second gear 522. Therefore, when the first clutch 610 is engaged, the input shaft 300 can transmit power to the output shaft 400 through the first gear pair 520.

[0114] Furthermore, the second clutch 620 connecting or disconnecting the input shaft 300 or output shaft 400 from the third gear 531, or connecting or disconnecting the input shaft 300 or output shaft 400 from the fourth gear 532, means that the second clutch 620 can control the power transmission at the third gear 531 or the fourth gear 532. Therefore, when the second clutch 620 is engaged, the input shaft 300 can transmit power to the output shaft 400 through the second gear pair 530.

[0115] In some specific embodiments of the present invention, such as Figure 2 As shown, the first gear 521 and the third gear 531 are located on the input shaft 300, and the second gear 522 and the fourth gear 532 are located on the output shaft 400.

[0116] Wherein, the first clutch 610 is disposed on the input shaft 300 and connects or disconnects the input shaft 300 from the first gear 521, or the first clutch 610 is disposed on the output shaft 400 and connects or disconnects the output shaft 400 from the second gear 522; and

[0117] The second clutch 620 is located on the input shaft 300 and connects or disconnects the input shaft 300 from the third gear 531; or, the second clutch 620 is located on the output shaft 400 and connects or disconnects the output shaft 400 from the fourth gear 532.

[0118] Therefore, the first clutch 610 can be located on the input shaft 300 and control the power transmission between the input shaft 300 and the first gear 521, while the second clutch 620 can be located on the input shaft 300 and control the power transmission between the input shaft 300 and the third gear 531; or, the first clutch 610 can be located on the input shaft 300 and control the power transmission between the input shaft 300 and the first gear 521, while the second clutch 620 can be located on the output shaft 400 and control the power transmission between the output shaft 400 and the fourth gear 532; Alternatively, the first clutch 610 can be located on the output shaft 400 and control the power transmission between the output shaft 400 and the second gear 522, while the second clutch 620 can be located on the input shaft 300 and control the power transmission between the input shaft 300 and the third gear 531; or, the first clutch 610 can be located on the output shaft 400 and control the power transmission between the output shaft 400 and the second gear 522, while the second clutch 620 can be located on the output shaft 400 and control the power transmission between the output shaft 400 and the fourth gear 532.

[0119] In other words, the first clutch 610 and the second clutch 620 can be simultaneously located on the input shaft 300 or the output shaft 400, or one of the first clutch 610 and the second clutch 620 can be located on the input shaft 300 and the other on the output shaft 400.

[0120] Furthermore, such as Figure 2 As shown, the first clutch 610 is located on one of the input shaft 300 and the output shaft 400, and the second clutch 620 is located on the other of the input shaft 300 and the output shaft 400. This arrangement allows the first clutch 610 and the second clutch 620 to be staggered on different shafts, which helps to reduce the space occupied by the clutch 600 in the longitudinal direction of the hybrid power system 1.

[0121] In some specific embodiments of the present invention, such as Figure 2 As shown, the hybrid power system 1 also includes a reduction mechanism 800, which includes a first output gear 810 and a second output gear 820.

[0122] The first output gear 810 is located on the motor shaft 101 of the first motor 100 and connected to the motor shaft 101 of the first motor 100. The second output gear 820 is located on the input shaft 300 and connected to the input shaft 300. The first output gear 810 and the second output gear 820 mesh.

[0123] The transmission ratio of the first output gear 810 and the second output gear 820 is greater than 1. In this way, the power of the first motor 100 can be reduced and transmitted to the input shaft 300 through the first output gear 810 and the second output gear 820, which helps to increase the output torque of the first motor 100 and make the power output of the first motor 100 more powerful.

[0124] Furthermore, by setting a reduction mechanism 800 to connect the motor shaft 101 and the input shaft 300 of the first motor 100, the motor shaft 101 and the input shaft 300 can be staggered in the radial direction of the input shaft 300, thereby reducing the space occupied by the motor shaft 101 and the input shaft 300 in the longitudinal direction of the hybrid power system 1, so as to make the longitudinal structure of the hybrid power system 1 more compact.

[0125] In some specific embodiments of the present invention, such as Figure 2 , Figures 17-19 As shown, the hybrid power system 1 also includes a third clutch 310, which is located between the engine shaft 210 and the input shaft 300 of the engine 200 to connect or disconnect the engine shaft 210 and the input shaft 300.

[0126] Specifically, by engaging the third clutch 310, the power of the engine 200 can be transmitted to the input shaft 300, and then transmitted backward through the input shaft 300. For example, the power can be transmitted to the output shaft 400 to drive the wheels, or it can be transmitted to the first motor 100 to drive the first motor 100 to generate electricity. When the third clutch 310 is disengaged, the power of the engine 200 is interrupted, and the engine 200 does not participate in the power drive of the hybrid power system 1.

[0127] Therefore, by setting the third clutch 310, the first motor 100 can be driven independently, or the first motor 100 and the engine 200 can be driven in a mixed manner.

[0128] In some specific embodiments of the present invention, such as Figure 2 , Figures 17-19 As shown, the hybrid power system 1 also includes a differential 900, which has a first bevel gear 910 and a second bevel gear 420 at the end of the output shaft 400. The first bevel gear 910 meshes with the second bevel gear 420. In this way, the transmission direction of power can be changed by the engagement of the first bevel gear 910 and the second bevel gear 420, that is, the power transmitted axially along the output shaft 400 can be changed to the power transmitted radially along the output shaft 400.

[0129] Furthermore, the first gear pair 520 and the second gear pair 530 can be directly mounted on the output shaft 400, and the shaft end of the output shaft 400 can be directly connected to the differential 900 through the second bevel gear 420, which further simplifies the structure of the hybrid power system 1, helps to simplify the number of gears in the hybrid power system 1, makes the force transmission structure simpler, and is easier to arrange.

[0130] Therefore, the hybrid power system 1 in this embodiment of the invention can realize the following operating conditions: front-wheel drive pure electric first gear, front-wheel drive pure electric second gear, rear-wheel drive pure electric, four-wheel drive pure electric first gear, four-wheel drive pure electric second gear, engine direct drive first gear, engine direct drive second gear, engine generating electricity and rear-wheel drive, parallel front-wheel drive first gear, parallel front-wheel drive second gear, engine and second motor in parallel four-wheel drive first gear, engine and second motor in parallel four-wheel drive second gear, engine and first motor and second motor in parallel four-wheel drive first gear, and engine and first motor and second motor in parallel four-wheel drive second gear.

[0131] Specifically, such as Figure 3As shown, when the hybrid system 1 is in front-drive pure electric first gear, the third clutch 310 disengages and the second motor 110 stops running. The first clutch 610 engages with the first gear pair 520, and the power of the first motor 100 can be transmitted to the differential 900 in sequence through the reduction mechanism 800, the input shaft 300, the first gear pair 520 and the output shaft 400, thereby driving the front wheel 920 to rotate.

[0132] like Figure 4 As shown, when the hybrid system 1 is in front-drive pure electric second gear, the third clutch 310 disengages and the second motor 110 stops running. The first clutch 610 engages with the second gear pair 530, and the power of the first motor 100 can be transmitted to the differential 900 in sequence through the reduction mechanism 800, the input shaft 300, the second gear pair 530 and the output shaft 400, thereby driving the front wheel 920 to rotate.

[0133] like Figure 5 As shown, when the hybrid system 1 is in rear-drive pure electric mode, the engine 200 and the first motor 100 stop running, and the hybrid system 1 drives the rear wheel 930 to rotate only through the second motor 110.

[0134] like Figure 6 As shown, when the hybrid system 1 is in four-wheel drive pure electric first gear, the third clutch 310 can be disengaged, the first clutch 610 engages with the first gear pair 520, and the power of the first motor 100 can be transmitted to the differential 900 through the reduction mechanism 800, the input shaft 300, the first gear pair 520 and the output shaft 400 in sequence, thereby driving the front wheel 920 to rotate, while the second motor 110 drives the rear wheel 930 to rotate.

[0135] like Figure 7 As shown, when the hybrid system 1 is in four-wheel drive pure electric second gear, the third clutch 310 can be disengaged, the first clutch 610 engages with the second gear pair 530, and the power of the first motor 100 can be transmitted to the differential 900 through the reduction mechanism 800, the input shaft 300, the second gear pair 530 and the output shaft 400 in sequence, thereby driving the front wheel 920 to rotate, while the second motor 110 drives the rear wheel 930 to rotate.

[0136] like Figure 8 As shown, when the hybrid system 1 is in engine direct drive first gear, the third clutch 310 is engaged, and the first motor 100 and the second motor 110 stop running. The first clutch 610 is engaged with the first gear pair 520, and the power of the engine 200 can be transmitted to the differential 900 in sequence through the input shaft 300, the first gear pair 520 and the output shaft 400, thereby driving the front wheel 920 to rotate.

[0137] like Figure 9 As shown, when the hybrid system 1 is in engine direct drive second gear, the third clutch 310 is engaged, and the first motor 100 and the second motor 110 stop running. The first clutch 610 is engaged with the second gear pair 530, and the power of the engine 200 can be transmitted to the differential 900 in sequence through the input shaft 300, the second gear pair 530 and the output shaft 400, thereby driving the front wheel 920 to rotate.

[0138] like Figure 10 As shown, when the hybrid system 1 is in the state of engine power generation and rear drive, the third clutch 310 is engaged, and the clutch 600 is disengaged from the first gear pair 520 and the second gear pair 530 respectively. The engine 200 transmits power to the first motor 100 to generate electricity through the input shaft 300 and the reduction mechanism 800, while the second motor 110 drives the rear wheel 930 to rotate.

[0139] like Figure 11 As shown, when the hybrid system 1 is in parallel front-drive first gear, the third clutch 310 engages, the second motor 110 stops running, the first clutch 610 engages with the first gear pair 520, the power of the engine 200 can be transmitted to the input shaft 300, and the power of the first motor 100 can be transmitted to the input shaft 300 through the reduction mechanism 800. The power of the engine 200 and the power of the first motor 100 are combined at the input shaft 300 and then transmitted to the differential 900 through the first gear pair 520 and the output shaft 400, thereby driving the front wheels 920 to rotate.

[0140] like Figure 12 As shown, when the hybrid system 1 is in parallel front-drive second gear, the third clutch 310 engages, and the second motor 110 stops running. The first clutch 610 engages with the second gear pair 530, and the power of the engine 200 can be transmitted to the input shaft 300. The power of the first motor 100 can also be transmitted to the input shaft 300 through the reduction mechanism 800. The power of the engine 200 and the power of the first motor 100 are combined at the input shaft 300 and then transmitted to the differential 900 through the second gear pair 530 and the output shaft 400, thereby driving the front wheels 920 to rotate.

[0141] like Figure 13 As shown, when the hybrid system 1 is in parallel four-wheel drive first gear with the engine and the second motor, the third clutch 310 is engaged, and the first motor 100 stops running. The first clutch 610 is engaged with the first gear pair 520, and the power of the engine 200 can be transmitted to the differential 900 in sequence through the input shaft 300, the first gear pair 520 and the output shaft 400, thereby driving the front wheel 920 to rotate. At the same time, the second motor 110 drives the rear wheel 930 to rotate.

[0142] like Figure 14 As shown, when the hybrid system 1 is in parallel four-wheel drive second gear with the engine and the second motor, the third clutch 310 engages, and the first motor 100 stops running. The first clutch 610 engages with the second gear pair 530, and the power of the engine 200 can be transmitted to the differential 900 in sequence through the input shaft 300, the second gear pair 530 and the output shaft 400, thereby driving the front wheel 920 to rotate. At the same time, the second motor 110 drives the rear wheel 930 to rotate.

[0143] like Figure 15 As shown, when the hybrid system 1 is in parallel four-wheel drive first gear with the engine, first motor and second motor connected, the third clutch 310 engages, the first clutch 610 engages with the first gear pair 520, the power of the engine 200 can be transmitted to the input shaft 300, and the power of the first motor 100 can be transmitted to the input shaft 300 through the reduction mechanism 800. The power of the engine 200 and the power of the first motor 100 are combined at the input shaft 300 and then transmitted to the differential 900 through the first gear pair 520 and the output shaft 400, thereby driving the front wheel 920 to rotate, while the second motor 110 drives the rear wheel 930 to rotate.

[0144] like Figure 16 As shown, when the hybrid system 1 is in parallel four-wheel drive second gear with the engine, first motor and second motor, the third clutch 310 engages, the first clutch 610 engages with the second gear pair 530, the power of the engine 200 can be transmitted to the input shaft 300, and the power of the first motor 100 can be transmitted to the input shaft 300 through the reduction mechanism 800. The power of the engine 200 and the power of the first motor 100 are combined at the input shaft 300 and then transmitted to the differential 900 through the second gear pair 530 and the output shaft 400, thereby driving the front wheel 920 to rotate, while the second motor 110 drives the rear wheel 930 to rotate.

[0145] In other specific embodiments of the present invention, such as Figure 17 and Figure 18 As shown, the hybrid power system 1 also includes an intermediate shaft 700, which is located between the input shaft 300 and the output shaft 400.

[0146] The first gear pair 520 and the second gear pair 530 are respectively located on the input shaft 300 and the intermediate shaft 700; or, the first gear pair 520 and the second gear pair 530 are respectively located on the intermediate shaft 700 and the output shaft 400.

[0147] By setting the intermediate shaft 700, the arrangement of the first gear pair 520 and the second gear pair 530 can be more diversified, that is, the arrangement of the hybrid power system 1 can be more diversified, which is conducive to optimizing the spatial arrangement of the hybrid power assembly. Moreover, more gears can be set for the power transmission between the input shaft 300 and the output shaft 400, which can further reduce the power output of the input shaft 300, thereby further increasing the torque of the input shaft 300, so that the power of the hybrid power system 1 is more sufficient.

[0148] Furthermore, such as Figure 17 As shown, the first gear 521 and the third gear 531 are located on the input shaft 300, and the second gear 522 and the fourth gear 532 are located on the intermediate shaft 700.

[0149] Wherein, the first clutch 610 is disposed on the input shaft 300 and connects the input shaft 300 to the first gear 521, or, the first clutch 610 is disposed on the intermediate shaft 700 and connects the intermediate shaft 700 to the second gear 522; or,

[0150] The second clutch 620 is located on the input shaft 300 and connects the input shaft 300 to the third gear 531, or the second clutch 620 is located on the intermediate shaft 700 and connects the intermediate shaft 700 to the fourth gear 532.

[0151] Therefore, the first clutch 610 can be located on the input shaft 300 and control the input shaft 300 to be connected to the first gear 521, while the second clutch 620 can be located on the input shaft 300 and control the input shaft 300 to be connected to the third gear 531; or, the first clutch 610 can be located on the input shaft 300 and control the input shaft 300 to be connected to the first gear 521, while the second clutch 620 can be located on the intermediate shaft 700 and control the intermediate shaft 700 to be connected to the fourth gear 532; or, the first clutch 610 can be located on the intermediate shaft 700 and control the intermediate shaft 700 to be connected to the second gear 522, while the second clutch 620 can be located on the input shaft 300 and control the input shaft 300 to be connected to the third gear 531; or, the first clutch 610 can be located on the intermediate shaft 700 and control the intermediate shaft 700 to be connected to the second gear 522, while the second clutch 620 can be located on the intermediate shaft 700 and control the intermediate shaft 700 to be connected to the fourth gear 532.

[0152] In other words, the first clutch 610 and the second clutch 620 can be simultaneously located on the input shaft 300 or the intermediate shaft 700, or one of the first clutch 610 and the second clutch 620 can be located on the input shaft 300 and the other on the intermediate shaft 700.

[0153] Furthermore, such as Figure 17As shown, the hybrid power system 1 also includes a first transmission gear 410, which is disposed on and connected to the output shaft 400.

[0154] The first clutch 610 is located on the intermediate shaft 700 and the second clutch 620 is located on the input shaft 300; the first transmission gear 410 meshes with the fourth gear 532; or

[0155] The first clutch 610 is located on the input shaft 300 and the second clutch 620 is located on the intermediate shaft 700. The first transmission gear 410 meshes with the second gear 522.

[0156] In other words, the first clutch 610 and the second clutch 620 need to be mounted on different shafts. When the first clutch 610 is mounted on the intermediate shaft 700 and the second clutch 620 is mounted on the input shaft 300, the first transmission gear 410 meshes with the fourth gear 532. Conversely, when the first clutch 610 is mounted on the input shaft 300 and the second clutch 620 is mounted on the intermediate shaft 700, the first transmission gear 410 meshes with the second gear 522. This ensures that when either the first clutch 610 or the second clutch 620 is engaged, the input shaft 300 can output power through the corresponding gear pair, enabling the hybrid power system 1 to drive the front wheels 920 to rotate normally.

[0157] In other specific embodiments of the present invention, such as Figure 18 As shown, the first gear 521 and the third gear 531 are located on the intermediate shaft 700, and the second gear 522 and the fourth gear 532 are located on the output shaft 400; wherein, the first clutch 610 is located on the intermediate shaft 700 and connects or disconnects the intermediate shaft 700 from the first gear 521, or, the first clutch 610 is located on the output shaft 400 and connects or disconnects the output shaft from the second gear 522; or

[0158] The second clutch 620 is located on the intermediate shaft 700 and connects or disconnects the intermediate shaft 700 from the third gear 531. The second clutch 620 is located on the output shaft 400 and connects or disconnects the output shaft 400 from the fourth gear 532.

[0159] Therefore, the first clutch 610 can be located on the intermediate shaft 700 and control the intermediate shaft 700 to be connected to the first gear 521, while the second clutch 620 can be located on the intermediate shaft 700 and control the intermediate shaft 700 to be connected to the third gear 531; or, the first clutch 610 can be located on the intermediate shaft 700 and control the intermediate shaft 700 to be connected to the first gear 521, while the second clutch 620 can be located on the output shaft 400 and control the output shaft 400 to be connected to the fourth gear 532; or, the first clutch 610 can be located on the output shaft 400 and control the output shaft 400 to be connected to the second gear 522, while the second clutch 620 can be located on the intermediate shaft 700 and control the intermediate shaft 700 to be connected to the third gear 531; or, the first clutch 610 can be located on the output shaft 400 and control the output shaft 400 to be connected to the second gear 522, while the second clutch 620 can be located on the output shaft 400 and control the output shaft 400 to be connected to the fourth gear 532.

[0160] In other words, the first clutch 610 and the second clutch 620 can be simultaneously located on the intermediate shaft 700 or the output shaft 400, or one of the first clutch 610 and the second clutch 620 can be located on the intermediate shaft 700 and the other on the output shaft 400.

[0161] Furthermore, such as Figure 18 As shown, the first clutch 610 is located on the intermediate shaft 700 and the second clutch 620 is located on the output shaft 400, and the third gear 531 is connected to the input shaft 300 for transmission; or

[0162] The first clutch 610 is located on the output shaft 400 and the second clutch 620 is located on the intermediate shaft 700. The first gear 521 is connected to the input shaft 300 for transmission.

[0163] In other words, the first clutch 610 and the second clutch 620 need to be mounted on different shafts. When the first clutch 610 is mounted on the intermediate shaft 700 and the second clutch 620 is mounted on the output shaft 400, the third gear 531 is connected to the input shaft 300. Conversely, when the first clutch 610 is mounted on the output shaft 400 and the second clutch 620 is mounted on the intermediate shaft 700, the first gear 521 is connected to the input shaft 300. This ensures that when either the first clutch 610 or the second clutch 620 is engaged, the input shaft 300 can output power through the corresponding gear pair, enabling the hybrid power system 1 to drive the front wheels 920 to rotate normally.

[0164] In some specific embodiments of the present invention, such as Figure 18 As shown, the hybrid power system 1 also includes a reduction mechanism 800, which includes a first output gear 810 and a second output gear 820.

[0165] The first output gear 810 is located on the motor shaft 101 of the first motor 100 and connected to the motor shaft 101 of the first motor 100. The second output gear 820 is located on the input shaft 300 and connected to the input shaft 300. One side of the second output gear 820 meshes with the first output gear 810, and the other side of the second output gear 820 meshes with the first gear 521 or the third gear 531.

[0166] The transmission ratio of the first output gear 810 and the second output gear 820 is greater than 1. In this way, the power of the first motor 100 can be reduced and transmitted to the input shaft 300 through the first output gear 810 and the second output gear 820, which helps to increase the output torque of the first motor 100 and make the power output of the first motor 100 more powerful.

[0167] Furthermore, the second output gear 820 can also mesh with the first gear 521 or the third gear 531, thereby transmitting the power from the input shaft 300 to the gear pair via the second output gear 820, and then to the output shaft 400. In other words, the first motor 100 can input power to the input shaft 300 and the input shaft 300 can output power to the gear pair through a single second output gear 820. This simplifies the structure of the hybrid power system 1 and further improves its compactness.

[0168] In other specific embodiments of the present invention, such as Figure 19 As shown, the clutch 600 is a dual clutch 630, and the dual clutch 630 is located between the first gear pair 520 and the second gear pair 530 to connect or disconnect the input shaft 300 and / or the output shaft 400 from the first gear pair 520 or the second gear pair 530. This arrangement reduces the number of components in the hybrid power system 1, thereby further improving the structural compactness of the hybrid power system 1, reducing the space occupied by the hybrid power system 1, and facilitating its layout.

[0169] In some specific embodiments of the present invention, such as Figure 19 As shown, the first gear pair 520 includes a first gear 521 and a second gear 522 that mesh with each other, and the second gear pair 530 includes a third gear 531 and a fourth gear 532 that mesh with each other.

[0170] The dual clutch 630 is disposed between the first gear 521 and the third gear 531 to connect or disconnect the input shaft 300 or the output shaft 400 from the first gear 521 or the third gear 531; and / or, the dual clutch 630 is disposed between the second gear 522 and the fourth gear 532 to connect or disconnect the input shaft 300 or the output shaft 400 from the second gear 522 or the fourth gear 532.

[0171] Specifically, the dual clutch 630 can be located only between the first gear 521 and the third gear 531, and can be selectively engaged with either the first gear 521 or the third gear 531, thereby enabling power transmission to the output shaft 400 via either the first gear pair 520 or the second gear pair 530; alternatively, the dual clutch 630 can be located only between the second gear 522 and the fourth gear 532, and can be selectively engaged with either the second gear 522 or the fourth gear 532, thereby enabling power transmission to the output shaft 400 via either the first gear pair 520 or the second gear pair 530. This configuration simplifies the structure of the dual clutch 630 and facilitates its arrangement.

[0172] Alternatively, the dual clutch 630 can be simultaneously positioned between the first gear 521 and the third gear 531, as well as between the second gear 522 and the third gear 531. The dual clutch 630 can be selectively engaged with the first gear 521 and the second gear 522, or selectively engaged with the third gear 531 and the fourth gear 532. This allows power to be transmitted to the output shaft 400 via the first gear pair 520 or the second gear pair 530. With this configuration, when the dual clutch 630 is engaged, the cooperation between the clutch 600 and the gear pair is more reliable, and the power transmission is more stable.

[0173] In some specific embodiments of the present invention, such as Figure 19 As shown, the hybrid power system 1 also includes an intermediate shaft 700, which is located between the input shaft 300 and the output shaft 400. A first gear 521 and a third gear 531 are located on the intermediate shaft 700, and a second transmission gear 710 is provided on the intermediate shaft 700. The second transmission gear 710 is connected to the input shaft 300 in a transmission manner.

[0174] By setting the intermediate shaft 700, the arrangement of the first gear pair 520 and the second gear pair 530 can be more diversified, that is, the arrangement of the hybrid power system 1 can be more diversified, which is conducive to optimizing the spatial arrangement of the hybrid power assembly. Moreover, more gears can be set for power transmission between the input shaft 300 and the output shaft 400. For example, a second transmission gear 710 can be added to transmit power to the input shaft 300, which can further reduce the power output of the input shaft 300, thereby further increasing the torque of the input shaft 300, so that the power of the hybrid power system 1 is more sufficient.

[0175] In some specific embodiments of the present invention, such as Figure 19 As shown, the hybrid power system 1 also includes a reduction mechanism 800, which includes a first output gear 810 and a second output gear 820.

[0176] The first output gear 810 is located on the motor shaft 101 of the first motor 100 and connected to the motor shaft 101 of the first motor 100. The second output gear 820 is located on the input shaft 300 and connected to the input shaft 300. One side of the second output gear 820 meshes with the first output gear 810, and the other side of the second output gear 820 meshes with the second transmission gear 710.

[0177] The transmission ratio of the first output gear 810 and the second output gear 820 is greater than 1. In this way, the power of the first motor 100 can be reduced and transmitted to the input shaft 300 through the first output gear 810 and the second output gear 820, which helps to increase the output torque of the first motor 100 and make the power output of the first motor 100 more powerful.

[0178] Furthermore, the second output gear 820 can also mesh with the second transmission gear 710, thereby transmitting the power from the input shaft 300 to the intermediate shaft 700 via the second output gear 820, and then to the output shaft 400 via the gear pair. In other words, the first motor 100 can input power to the input shaft 300 and output power from the input shaft 300 to the intermediate shaft 700 through a single second output gear 820. This simplifies the structure of the hybrid power system 1 and further improves its compactness.

[0179] In some embodiments of the present invention, such as Figure 20 As shown, the gear pair includes a fifth gear 540 and a sixth gear 541 that mesh with each other. The fifth gear 540 is driven to the input shaft 300, and the sixth gear 541 is driven to the output shaft 400. The clutch 600 connects or disconnects the input shaft 300 from the fifth gear 540, or connects or disconnects the output shaft 400 from the sixth gear 541.

[0180] In other words, clutch 600 can control or interrupt the power transmission between input shaft 300 and fifth gear 540, or clutch 600 can control or interrupt the power transmission between sixth gear 541 and output shaft 400. This configuration allows clutch 600 to control the power transmission or interruption between input shaft 300 and output shaft 400, thereby controlling the first motor 100 and / or engine 200 to output power to output shaft 400 via input shaft 300.

[0181] In some embodiments of the present invention, such as Figure 20 As shown, the hybrid power system also includes an intermediate shaft 700, which is located between the input shaft 300 and the output shaft 400, and is drively connected to the input shaft 300.

[0182] Specifically, the fifth gear 540 is located on the intermediate shaft 700 and the sixth gear 541 is located on the output shaft 400. The clutch 600 is located on the intermediate shaft 700 and connects or disconnects the intermediate shaft 700 from the fifth gear 540. Alternatively, the clutch 600 is located on the output shaft 400 and connects or disconnects the output shaft 400 from the sixth gear 541.

[0183] In other words, the clutch 600 can be arranged in multiple ways. For example, the clutch 600 can be located on the intermediate shaft 700, and by controlling the engagement and disengagement of the clutch 600, the power transmission between the intermediate shaft 700 and the fifth gear 540 can be controlled or interrupted. Alternatively, the clutch 600 can be located on the output shaft 400, and by controlling the engagement and disengagement of the clutch 600, the power transmission between the output shaft 400 and the sixth gear 541 can be controlled or interrupted. This arrangement allows for control of the power output between the input shaft 300 and the output shaft 400, and provides greater versatility in the clutch 600's arrangement.

[0184] In some embodiments of the present invention, such as Figure 20 As shown, the hybrid power system also includes a reduction mechanism 800, which includes a first output gear 810 and a second output gear 820.

[0185] The first output gear 810 is located on and connected to the input shaft 300, and the second output gear 820 is located on and connected to the intermediate shaft 700. The second output gear 820 meshes with the first output gear 810.

[0186] The transmission ratio of the first output gear 810 and the second output gear 820 is greater than 1. In this way, the power of the first motor 100 can be reduced and transmitted to the input shaft 300 through the first output gear 810 and the second output gear 820, which helps to increase the output torque of the first motor 100 and make the power output of the first motor 100 more powerful.

[0187] In some embodiments of the present invention, such as Figure 20 As shown, the motor shaft 101 of the first motor 100 is coaxially arranged with and connected to the input shaft 300. This allows the space occupied by the motor shaft 101 and the input shaft 300 in the left and right directions to be smaller, and makes the structural layout simpler.

[0188] In other embodiments of the invention, such as Figure 21 As shown, a third output gear 102 is provided on the motor shaft 101, and the two sides of the first output gear 810 mesh with the third output gear 102 and the second output gear 820 respectively.

[0189] With this configuration, the motor shaft 101 and the input shaft 300 can be staggered in the radial direction of the input shaft 300, thereby reducing the space occupied by the motor shaft 101 and the input shaft 300 in the longitudinal direction of the hybrid power system 1, making the longitudinal structure of the hybrid power system 1 more compact. Furthermore, the third output gear 102 and the first output gear 810 can also transmit speed reduction to further increase the output torque of the first motor.

[0190] In some embodiments of the present invention, such as Figure 22 As shown, the first motor 100 has a third output gear 102 on its motor shaft 101, a fifth gear 540 on its input shaft 300 and a sixth gear 541 on its output shaft 400. The third output gear 102 and the fifth gear 540 mesh, and the clutch 600 is located on the output shaft 400 and connects or disconnects the output shaft 400 from the sixth gear 541.

[0191] This configuration helps reduce the number of gears in the hybrid power system 1, making the structure of the hybrid power system 1 simpler. The input shaft 300 can directly drive the fifth gear 540 to rotate, so the power of the engine 200 can be directly transmitted to the output shaft 400 through the input shaft 300, the fifth gear 540, and the sixth gear 541. The power of the first motor 100 can be transmitted to the output shaft 400 through the third output gear 102, the fifth gear 540, and the sixth gear 541. The power transmission path is simpler, and the power of the first motor 100 and the engine 200 can be disconnected from the output shaft 400 by disengaging the clutch 600.

[0192] In some embodiments of the present invention, such as Figure 23 As shown, the hybrid power system also includes an intermediate shaft 700 and a fourth output gear 720. The intermediate shaft 700 is located between the input shaft 300 and the output shaft 400. The fifth gear 540 is located on the intermediate shaft 700 and the sixth gear 541 is located on the output shaft 400. The fourth output gear 720 is located on the input shaft 300 and meshes with the fifth gear 540.

[0193] The clutch 600 is located on the output shaft 400 and connects or disconnects the output shaft 400 from the sixth gear 541.

[0194] With this configuration, the fourth output gear 720 and the fifth gear 540 can reduce the speed of the engine 200 and the first motor 100, thereby increasing the output torque of the first motor 100 and the engine 200, and making the power output of the first motor 100 and the engine 200 more powerful.

[0195] In some embodiments of the present invention, the fifth gear 540 is disposed on and connected to the input shaft 300, and the sixth gear 541 is disposed on and connected to the output shaft 400.

[0196] like Figure 24 As shown, the motor shaft 101 of the first motor 100 and the input shaft 300 are coaxially arranged, and the clutch 600 is located between the input shaft 300 and the motor shaft 101 of the first motor 100 to connect or disconnect the input shaft 300 and the motor shaft 101 of the first motor 100. This can further reduce the number of gears in the hybrid power system 1, making the structure of the hybrid power system 1 simpler.

[0197] Or, such as Figure 25 As shown, a third output gear 102 is provided on the motor shaft 101. The third output gear 102 meshes with a fifth gear 540. A clutch 600 is located between the motor shaft 101 and the third output gear 102 to connect or disconnect the motor shaft 101 and the third output gear 102. This arrangement not only reduces the number of gears in the hybrid power system 1, but also allows the third output gear 102 and the fifth gear 540 to reduce the power output of the first motor 100, thereby increasing the output torque of the first motor 100.

[0198] In some embodiments of the present invention, such as Figure 26 As shown, the hybrid power system also includes a planetary gear mechanism 140, which includes a ring gear 141, multiple planetary gears 142, a planet carrier 143, and a sun gear 144. The planet carrier 143 is connected to the multiple planetary gears 142 and the input shaft 300, respectively. The sun gear 144 is connected to the motor shaft 101 of the first motor 100, and the planetary gears 142 mesh between the sun gear 144 and the ring gear 141.

[0199] By setting up the planetary gear mechanism 140, the planetary gear mechanism 140 can more effectively improve the output torque of the first motor 100, and can further optimize the efficiency matching between the engine 200 and the first motor 100, which is beneficial to improving the power performance of the hybrid power system 1.

[0200] In some embodiments of the present invention, such as Figure 27 As shown, the gear pair includes a seventh gear 550, an eighth gear 551, and a ninth gear 552.

[0201] The seventh gear 550 is located on and connected to the motor shaft 101 of the first motor 100, the eighth gear 551 is located on and connected to the input shaft 300, the ninth gear 552 is sleeved on the output shaft 400, and the clutch 600 is located on the output shaft 400 and connects or disconnects the output shaft 400 from the ninth gear 552.

[0202] In this way, the engine shaft 210 of the engine 200 can be coaxially arranged with the input shaft 300, and the motor shaft 101 can be located between the input shaft 300 and the output shaft 400. The closer distance between the motor shaft 101 and the output shaft 400 helps to simplify the power transmission structure between the motor shaft 101 and the output shaft 400. Furthermore, the input shaft 300, the motor shaft 101, and the output shaft 400 can be staggered in the radial direction of the input shaft 300, thereby reducing the space occupied by the input shaft 300, the motor shaft 101, and the output shaft 400 in the longitudinal direction of the hybrid power system 1, so as to make the longitudinal structure of the hybrid power system 1 more compact.
