The compact structure and high transmission efficiency of the first planetary gear mechanism 20 enable it to maintain high reliability during its service life.

[0041] The meshing relationship between the first sun gear 21, the first planet gear 22, the first planet carrier 23 and the first ring gear 24 enables the hybrid power system 100 to dynamically adjust the power transmission path according to the working condition requirements of the vehicle. The engine 11 is in transmission connection with the first planet carrier 23, so that the power of the engine 11 can be input through the first planet carrier 23, the generator 12 is in transmission connection with the first sun gear 21, so that the speed and torque of the generator 12 can be adjusted as required, and at the same time, the generator 12 can also provide power or recover energy to the first planetary gear mechanism 20 through the first sun gear 21, and when recovering energy, the generator 12 generates electricity. By changing the relative motion relationship of each component in the first planetary gear mechanism 20, the power transmission path and the transmission ratio can be flexibly adjusted, so that the hybrid power system 100 can reasonably distribute the power output of the engine 11 and the generator 12 according to the working condition requirements.

[0043] Specifically, when the generator 12 and the drive motor 13 provide power at the same time, the first sun gear 21 is disconnected from the housing 10, the transmission mechanism 30 is combined with the first sun gear 21, and the transmission mechanism 30 is in transmission connection with the drive motor 13 and the power output mechanism 40, it is a pure electric mode of the generator 12 and the drive motor 13 driving at the same time, and in turn the effect of the generator 12 and the drive motor 13 driving the vehicle with large output torque at the same time can be achieved.

[0044] When the drive motor 13 provides power alone, the first sun gear 21 is combined with the housing 10, the transmission mechanism 30 is disconnected from the first sun gear 21, and the transmission mechanism 30 is in transmission connection with the drive motor 13 and the power output mechanism 40, it is a pure electric mode of the drive motor 13 driving alone.

[0045] When the engine 11 and the generator 12 provide power at the same time, the first sun gear 21 is disconnected from the housing 10, the transmission mechanism 30 is combined with the first ring gear 24, and the transmission mechanism 30 is in transmission connection with the drive motor 13 and the power output mechanism 40, it is an E-CVT mode of the engine 11 and the generator 12 driving at the same time.

[0046] When the engine 11, the generator 12, and the drive motor 13 provide power at the same time, the first sun gear 21 is disconnected from the housing 10, the transmission mechanism 30 is combined with the first ring gear 24, and the transmission mechanism 30 is in transmission connection with the drive motor 13 and the power output mechanism 40, it is a hybrid mode of the engine 11, the generator 12, and the drive motor 13 driving together.

[0047] When the engine 11 provides power alone, the first sun gear 21 is combined with the housing 10, the transmission mechanism 30 is combined with the first ring gear 24, and the transmission mechanism 30 is in transmission connection with the drive motor 13 and the power output mechanism 40, it is an engine 11 direct drive mode.

[0048] According to the hybrid power system 100 of the vehicle, the first planetary gear mechanism 20, the transmission mechanism 30 and the power output mechanism 40 are arranged, the first planetary gear 22 is rotatably arranged on the first planetary carrier 23, the first sun gear 21 is in transmission connection with the generator 12, the engine 11 is in transmission connection with the first planetary carrier 23, the transmission mechanism 30 is in transmission connection with the driving motor 13 and the power output mechanism 40, the transmission mechanism 30 is selectively combined with or disconnected from the first ring gear 24, the first sun gear 21 is selectively combined with or disconnected from the shell 10, and the first sun gear 21 is also selectively combined with or disconnected from the transmission mechanism 30, so that the generator 12 and the driving motor 13 can drive the vehicle at the same time, and the vehicle also has different driving modes such as the pure electric mode, the E-CVT mode, the hybrid mode and the engine 11 direct drive mode.

[0049] According to some embodiments of the utility model, Figure 1 and Figure 2 As shown, the hybrid power system 100 of the vehicle further comprises: a first combination mechanism 50, the first combination mechanism 50 selectively combines or disconnects the shell 10 and the first sun gear 21; a second combination mechanism 60, the second combination mechanism 60 is arranged on the transmission mechanism 30, and the second combination mechanism 60 has a first combination position 61, a second combination position 62 and a third combination position 63, the second combination mechanism 60 combines the transmission mechanism 30 and the first ring gear 24 when being at the first combination position 61, the second combination mechanism 60 combines the transmission mechanism 30 and the first sun gear 21 when being at the second combination position 62, and the second combination mechanism 60 is disconnected from the first ring gear 24 and the first sun gear 21 when being at the third combination position 63.

[0050] Among them, the first combination mechanism 50 and the second combination mechanism 60 can be synchronizers, clutches, splines and other mechanisms that can realize the combination and disconnection functions, but the utility model is not limited to this, the first combination mechanism 50 and the second combination mechanism 60 can also be other mechanisms that can realize the combination and disconnection functions.

[0051] As Figure 1As shown, the first coupling mechanism 50 selectively couples or uncouples the housing 10 and the first sun gear 21, and the effect of coupling or uncoupling the housing 10 and the first sun gear 21 can be achieved, when the first coupling mechanism 50 selectively couples the housing 10 and the first sun gear 21, the single motor pure electric mode of driving the vehicle by the driving motor 13 alone can be achieved, or the engine 11 direct drive mode of driving the vehicle by the engine 11 alone can also be achieved. When the first coupling mechanism 50 selectively uncouples the housing 10 and the first sun gear 21, the driving mode of driving the vehicle by the generator 12 and the driving motor 13 at the same time (such as the double motor pure electric mode of driving the vehicle by the generator 12 and the driving motor 13 at the same time), or the driving mode of driving the vehicle by the engine 11 and the generator 12 together (such as the E-CVT mode), or the driving mode of driving the vehicle by the engine 11, the generator 12 and the driving motor 13 together (hybrid mode) can be achieved.

[0052] As shown in the figure, Figure 1 The second coupling mechanism 60 is arranged in the transmission mechanism 30, and the second coupling mechanism 60 has a first coupling position 61, a second coupling position 62 and a third coupling position 63. When the second coupling mechanism 60 is in the first coupling position 61, the transmission mechanism 30 and the first ring gear 24 are coupled, and the power of the engine 11 can be transmitted to the wheels through the transmission mechanism 30 and the first ring gear 24, achieving the driving mode of driving by the engine 11 alone (engine 11 direct drive mode), or the driving mode of driving by the engine 11 and the generator 12 together (such as E-CVT mode), or the driving mode of driving by the engine 11, the generator 12 and the driving motor 13 together (hybrid mode), which helps to provide sufficient driving force in low speed or in the case of requiring additional power.

[0053] When the second coupling mechanism 60 is in the second coupling position 62, the transmission mechanism 30 and the first sun gear 21 are coupled, and the driving mode of driving the vehicle by the generator 12 and the driving motor 13 at the same time (such as the double motor pure electric mode of driving the vehicle by the generator 12 and the driving motor 13 at the same time) can be achieved.

[0054] When the second coupling mechanism 60 is in the third coupling position 63, the first ring gear 24 and the first sun gear 21 are uncoupled, and the power of the engine 11 is no longer transmitted to the wheels through this path, and the driving motor 13 becomes the only power source, and the driving mode of driving the vehicle by the driving motor 13 alone (such as the single motor pure electric mode of driving the vehicle by the driving motor 13 alone) can be achieved.

[0055] According to some embodiments of the present application, as shown in the figure, Figure 1As shown, the hybrid power system 100 of the vehicle can further include a third coupling mechanism 70, the power output mechanism 40 includes a power output shaft 41 and a plurality of power output gears 42, the plurality of power output gears 42 are sleeved on the power output shaft 41 and rotatable relative to the power output shaft 41, the plurality of power output gears 42 are arranged in sequence along the axial direction of the power output shaft 41 and are in driving connection with the transmission mechanism 30, the transmission ratios of the plurality of power output gears 42 are different, and the third coupling mechanism 70 is arranged on the power output shaft 41 and selectively couples the power output shaft 41 and any one of the plurality of power output gears 42.

[0056] The third coupling mechanism 70 can be a synchronizer, a clutch, a spline or other mechanism capable of coupling and decoupling, but the utility model is not limited thereto.

[0057] The power output mechanism 40 can include the power output shaft 41 and the plurality of power output gears 42. In some embodiments of the utility model, the power output mechanism 40 can include two, three, four or other number of power output gears 42, but the utility model is not limited thereto. The power output mechanism 40 can also include other number of power output gears 42, as long as the power output mechanism 40 includes the power output shaft 41 and the plurality of power output gears 42. The application is described by taking the power output mechanism 40 including the power output shaft 41 and two power output gears 42 as an example.

[0058] The plurality of power output gears 42 are sleeved on the power output shaft 41 and rotatable relative to the power output shaft 41, the plurality of power output gears 42 are arranged in sequence along the axial direction of the power output shaft 41 and are in driving connection with the transmission mechanism 30, the transmission ratios of the plurality of power output gears 42 are different, and the third coupling mechanism 70 is arranged on the power output shaft 41 and selectively couples the power output shaft 41 and any one of the plurality of power output gears 42, so as to realize different transmission ratios and further realize gear shifting of the vehicle. The optimal transmission ratio can be selected flexibly according to the driving requirement, and the power output is optimized.

[0059] Through the third coupling mechanism 70 and the setting and matching of the power output mechanism 40, the hybrid power system 100 has the technical effects of flexible and various power output, adaptation to different working conditions, stable power coupling, efficient energy recovery, reliable and durable system, convenient maintenance and the like. These effects collectively improve the overall performance and user experience of the hybrid power system 100.

[0060] According to some embodiments of the utility model, as Figure 1As shown, the transmission mechanism 30 can include a transmission shaft 31 and a plurality of transmission gears 32, the plurality of transmission gears 32 are sleeved on the transmission shaft 31 and fixed to the transmission shaft 31, the plurality of transmission gears 32 are arranged in sequence along the axial direction of the transmission shaft 31, the plurality of transmission gears 32 and the plurality of power output gears 42 are one-to-one corresponding engagement, one of the plurality of transmission gears 32 is in transmission connection with the driving motor 13.

[0061] Among them, the transmission mechanism 30 can include a transmission shaft 31 and a plurality of transmission gears 32, in some embodiments of the utility model, the transmission shaft 31 can include two, three, four and the like number of transmission gears 32, but the utility model is not limited to this, the transmission shaft 31 can also include other number of transmission gears 32, as long as the transmission shaft 31 includes the power output shaft 41 and the plurality of transmission gears 32. The application is described by taking the transmission shaft 31 including the power output shaft 41 and two transmission gears 32 as an example.

[0062] The plurality of transmission gears 32 are sleeved on the transmission shaft 31 and fixed to the transmission shaft 31, the plurality of transmission gears 32 are arranged in sequence along the axial direction of the transmission shaft 31, the plurality of transmission gears 32 and the plurality of power output gears 42 are one-to-one corresponding engagement, the direct engagement of the transmission gear 32 and the power output gear 42 reduces the energy loss in the power transmission process, improves the transmission efficiency, one of the plurality of transmission gears 32 is in transmission connection with the driving motor 13, so that the power can be more efficiently transmitted from the driving motor 13 to the power output mechanism 40, and then drive the vehicle to travel. By setting the plurality of transmission gears 32, different transmission ratios can be selected according to different driving requirements, which helps to optimize the power output, so that the vehicle can maintain efficient power transmission under various working conditions.

[0063] According to some embodiments of the utility model, as shown in Figure 1 The plurality of power output gears 42 can include a first power output gear 421 and a second power output gear 422, the plurality of transmission gears 32 include a first transmission gear 321 and a second transmission gear 322, the first power output gear 421 and the first transmission gear 321 are opposite and engaged, the second power output gear 422 and the second transmission gear 322 are opposite and engaged, and the transmission ratio of the first power output gear 421 and the first transmission gear 321 is greater than the transmission ratio of the second power output gear 422 and the second transmission gear 322.

[0064] Wherein, due to the different transmission ratios, the first power output gear 421 and the second power output gear 422 can output different torques and rotational speeds respectively, so that the transmission mechanism 30 can flexibly distribute power to different driving components according to actual needs, meet diversified power requirements, and through adjusting the transmission ratio, the transmission mechanism 30 can adapt to different road conditions and driving needs, provide more comfortable and economical driving experience.

[0065] Further, the third coupling mechanism 70 selectively couples the power output shaft 41 and any one of the plurality of power output gears 42. Specifically, the third coupling mechanism 70 selectively couples the power output shaft 41 and any one of the first power output gear 421 and the second power output gear 422. When the third coupling mechanism 70 selectively couples the power output shaft 41 and the first power output gear 421, the first electric mode one gear or the first electric mode three gear of the vehicle, or the E-CVT mode one gear, or the hybrid mode one gear, or the engine 11 direct drive mode one gear can be realized. When the third coupling mechanism 70 selectively couples the power output shaft 41 and the second power output gear 422, the second electric mode one gear or the second electric mode four gear of the vehicle, or the E-CVT mode two gear, or the hybrid mode two gear, or the engine 11 direct drive mode two gear can be realized.

[0066] It can be explained that the transmission ratio of the first power output gear 421 and the first transmission gear 321 is greater than the transmission ratio of the second power output gear 422 and the second transmission gear 322. When the transmission ratio is large, the gear of the vehicle is small, and when the transmission ratio is small, the gear of the vehicle is high. By setting the transmission ratio of the first power output gear 421 and the first transmission gear 321 to be greater than the transmission ratio of the second power output gear 422 and the second transmission gear 322, and through the coupling or disconnection of the first coupling mechanism 50, the second coupling mechanism 60, the third coupling mechanism 70 and other components, the dynamic adjustment of the multiple driving modes and multiple gears of the vehicle can be realized, so that the vehicle has the electric mode, the E-CVT mode, the hybrid mode, and the engine 11 direct drive mode. The electric mode includes the double motor electric mode one gear, the double motor electric mode two gear, the single motor electric mode three gear, and the single motor electric mode four gear. The E-CVT mode includes the E-CVT mode one gear and the E-CVT mode two gear. The hybrid mode includes the hybrid mode one gear and the hybrid mode two gear. The engine 11 direct drive mode includes the engine 11 direct drive mode one gear and the engine 11 direct drive mode two gear.

[0128] Further, the second connecting shaft 26 can be connected between the engine 11 and the first carrier 23, so that the power of the engine 11 can be transmitted to the first carrier 23, the transmission shaft 31, the first connecting shaft 25 and the second connecting shaft 26 can be arranged in parallel, and the transmission shaft 31 and the second connecting shaft 26 can be arranged relatively, so that the whole hybrid power system 100 is more compact in layout, unnecessary space occupation is reduced, the structure of the hybrid power system 100 is simplified, and the complexity of manufacturing and installation is reduced.

[0129] The following will describe three specific embodiments of the hybrid power system 100 in detail.

[0130] As shown in Figure 1As shown, the hybrid system 100 of the first embodiment comprises a housing 10, an engine 11, a generator 12, a drive motor 13, a drive motor shaft 14, a power input gear 15, a first planetary gear mechanism 20, a first sun gear 21, a first planet gear 22, a first carrier 23, a first ring gear 24, a first connecting shaft 25, a second connecting shaft 26, a transmission mechanism 30, a transmission shaft 31, a transmission gear 32, a first transmission gear 321, a second transmission gear 322, a power output mechanism 40, a power output shaft 41, a power output gear 42, a first power output gear 421, a second power output gear 422, a first coupling mechanism 50, a second coupling mechanism 60, a third coupling mechanism 70, the second coupling mechanism 60 having a first coupling position 61, a second coupling position 62, and a third coupling position 63.

[0131] The first coupling mechanism 50 is arranged on the first connecting shaft 25, the first sun gear 21 is fixedly connected with the first connecting shaft 25, and the generator 12 is arranged between the first coupling mechanism 50 and the first sun gear 21. In the axial direction of the hybrid system 100, the engine 11 is arranged on the same side of the first planetary gear mechanism 20, the generator 12, and the first coupling mechanism 50, the engine 11 is in transmission connection with the second connecting shaft 26, and the first connecting shaft 25 is parallel to and spaced apart from the second connecting shaft 26. The transmission mechanism 30 comprises the transmission shaft 31, the first transmission gear 321, and the second transmission gear 322, the first transmission gear 321 and the second transmission gear 322 are arranged in sequence in the axial direction of the transmission shaft 31, the second coupling mechanism 60 is arranged on the transmission shaft 31 of the transmission mechanism 30, and the transmission shaft 31 is arranged opposite to the second connecting shaft 26.

[0132] In the axial direction of the hybrid system 100, the second coupling mechanism 60 is located on the other side of the first planetary gear mechanism 20, the second coupling mechanism 60 is arranged between the first planetary gear mechanism 20 and the first transmission gear 321, and the first transmission gear 321 is located between the second coupling mechanism 60 and the second transmission gear 322. The power output mechanism 40 comprises the power output shaft 41, the first power output gear 421, and the second power output gear 422, the first power output gear 421 and the first transmission gear 321 are opposite and in meshing connection, the second power output gear 422 and the second transmission gear 322 are opposite and in meshing connection, the transmission ratio of the first power output gear 421 and the first transmission gear 321 is greater than the transmission ratio of the second power output gear 422 and the second transmission gear 322, and the power output shaft 41 is parallel to and spaced apart from the transmission shaft 31.

[0133] The third coupling mechanism 70 is arranged on the power output shaft 41 and is located between the first power output gear 421 and the second power output gear 422. The third coupling mechanism 70 selectively couples the power output shaft 41 with the first power output gear 421 or the second power output gear 422 of the plurality of power output gears 42. The driving motor 13 is connected with a driving motor shaft 14, which is in transmission connection with the power input gear 15. The power input gear 15 is opposite to and in meshing connection with the second transmission gear 322. The driving motor shaft 14 is parallel to and spaced apart from the transmission shaft 31.

[0134] The first coupling mechanism 50 selectively couples or disconnects the housing 10 and the first sun gear 21. When the first coupling mechanism 50 selectively couples the housing 10 and the first sun gear 21, the single-motor pure electric mode of the driving motor 13 driving the vehicle alone can be realized, or the engine 11 direct drive mode of the engine 11 driving the vehicle alone can also be realized. When the first coupling mechanism 50 selectively disconnects the housing 10 and the first sun gear 21, the driving mode of the driving motor 13 and the generator 12 driving the vehicle simultaneously (such as the double-motor pure electric mode of the driving motor 13 and the generator 12 driving simultaneously), or the driving mode of the engine 11 and the generator 12 driving together (such as the E-CVT mode), or the driving mode of the engine 11, the generator 12 and the driving motor 13 driving together (hybrid mode) can be realized.

[0135] The second coupling mechanism 60 is arranged on the transmission mechanism 30 and has a first coupling position 61, a second coupling position 62 and a third coupling position 63. When the second coupling mechanism 60 is in the first coupling position 61, the transmission mechanism 30 and the first ring gear 24 are coupled. The power of the engine 11 can be transmitted to the wheels through the transmission mechanism 30 and the first ring gear 24, realizing the driving mode of the engine 11 driving alone (engine 11 direct drive mode), or the driving mode of the engine 11 and the generator 12 driving together (such as E-CVT mode), or the driving mode of the engine 11, the generator 12 and the driving motor 13 driving together (hybrid mode), which is helpful to provide sufficient driving force in low speed or in the case of requiring additional power.

[0136] When the second coupling mechanism 60 is in the second coupling position 62, the transmission mechanism 30 and the first sun gear 21 are coupled. The driving mode of the driving motor 13 and the generator 12 driving the vehicle simultaneously (such as the double-motor pure electric mode of the driving motor 13 and the generator 12 driving simultaneously) can be realized.

[0137] When in the third engagement position 63, the second engagement mechanism 60 is disconnected from the first gear ring 24 and the first sun gear 21. The power of the engine 11 is no longer transmitted to the wheels through this path, and the drive motor 13 becomes the only power source, which can realize the drive mode of the drive motor 13 driving the vehicle alone (such as the single motor pure electric mode of the drive motor 13 driving the vehicle alone).

[0138] The third engagement mechanism 70 is located on the power output shaft 41. The third engagement mechanism 70 selectively engages the power output shaft 41 with any one of the multiple power output gears 42 to achieve different transmission ratios, thereby enabling the vehicle to shift gears. The optimal transmission ratio can be flexibly selected according to driving needs to optimize power output.

[0139] Therefore, the combination and matching relationship between the components of the hybrid power system 100 of the first embodiment can form different driving modes as shown in Table 1 above.

[0140] like Figure 2 As shown, the hybrid power system 100 of the second embodiment includes: a housing 10, an engine 11, a generator 12, a drive motor 13, a drive motor shaft 14, a power input gear 15, a first planetary gear mechanism 20, a first sun gear 21, a first planetary gear 22, a first planetary carrier 23, a first ring gear 24, a first connecting shaft 25, a second connecting shaft 26, a transmission mechanism 30, a transmission shaft 31, a power output mechanism 40, a second sun gear 43, a second planetary gear 44, a second planetary carrier 45, a second ring gear 46, a first coupling mechanism 50, a second coupling mechanism 60, and a third coupling mechanism 70. The second coupling mechanism 60 has a first coupling position 61, a second coupling position 62, and a third coupling position 63.

[0141] The first coupling mechanism 50 is located on the first connecting shaft 25, the first sun gear 21 is drivenly connected to the first connecting shaft 25, and the generator 12 is located between the first coupling mechanism 50 and the first sun gear 21. The engine 11 is located on the same side of the first planetary gear mechanism 20, the generator 12, and the first coupling mechanism 50, and the engine 11 is drivenly connected to the second connecting shaft 26. The first connecting shaft 25 and the second connecting shaft 26 are parallel and spaced apart.

[0142] The transmission mechanism 30 comprises a transmission shaft 31, the second coupling mechanism 60 is arranged on the transmission shaft 31 of the transmission mechanism 30, the second coupling mechanism 60 is arranged between the first planetary gear mechanism 20 and the driving motor 13, and the transmission shaft 31 is arranged opposite to the second connecting shaft 26. The power output mechanism 40 comprises a second sun gear 43, a second planetary gear 44, a second planetary carrier 45 and a second ring gear 46, the second planetary gear 44 is engaged between the second sun gear 43 and the second ring gear 46, and the second planetary gear 44 is rotatably arranged on the second planetary carrier 45, the second planetary carrier 45 is configured as a power output end, the transmission shaft 31 is in transmission connection with the second sun gear 43, and the third coupling mechanism 70 is arranged on the second ring gear 46, and the third coupling mechanism 70 selectively couples the transmission shaft 31 or the housing 10.

[0143] The first coupling mechanism 50 selectively couples or disconnects the housing 10 and the first sun gear 21, and can realize the effect of coupling or disconnecting the housing 10 and the first sun gear 21. When the first coupling mechanism 50 selectively couples the housing 10 and the first sun gear 21, a single-motor pure electric mode of driving the vehicle by the driving motor 13 alone can be realized, or an engine 11 direct drive mode of driving the vehicle by the engine 11 alone can also be realized. When the first coupling mechanism 50 selectively disconnects the housing 10 and the first sun gear 21, a driving mode of driving the vehicle by the generator 12 and the driving motor 13 simultaneously (such as a double-motor pure electric mode of driving by the generator 12 and the driving motor 13 simultaneously), or a driving mode of driving by the engine 11 and the generator 12 together (such as an E-CVT mode), or a driving mode of driving by the engine 11, the generator 12 and the driving motor 13 together (a hybrid mode) can be realized.

[0144] The second coupling mechanism 60 is arranged on the transmission mechanism 30, and the second coupling mechanism 60 has a first coupling position 61, a second coupling position 62 and a third coupling position 63. When the second coupling mechanism 60 is in the first coupling position 61, the transmission mechanism 30 and the first ring gear 24 are coupled, and the power of the engine 11 can be transmitted to the wheels through the transmission mechanism 30 and the first ring gear 24, realizing a driving mode of driving by the engine 11 alone (an engine 11 direct drive mode), or a driving mode of driving by the engine 11 and the generator 12 together (such as an E-CVT mode), or a driving mode of driving by the engine 11, the generator 12 and the driving motor 13 together (a hybrid mode), which is helpful to provide sufficient driving force in low speed or in the case of requiring additional power.

[0145] When the second coupling mechanism 60 is in the second coupling position 62, the transmission mechanism 30 and the first sun gear 21 are coupled, and a driving mode of driving the vehicle by the generator 12 and the driving motor 13 simultaneously (such as a double-motor pure electric mode of driving by the generator 12 and the driving motor 13 simultaneously) can be realized.

[0146] When in the third engagement position 63, the second engagement mechanism 60 is disconnected from the first gear ring 24 and the first sun gear 21. The power of the engine 11 is no longer transmitted to the wheels through this path, and the drive motor 13 becomes the only power source, which can realize the drive mode of the drive motor 13 driving the vehicle alone (such as the single motor pure electric mode of the drive motor 13 driving the vehicle alone).

[0147] The third engagement mechanism 70 is located on the second gear ring 46. The third engagement mechanism 70 selectively engages the drive shaft 31 or the housing 10. When the third engagement mechanism 70 engages the drive shaft 31, it can realize pure electric mode, E-CVT mode, hybrid mode, and engine 11 direct drive mode. When the third engagement mechanism 70 disengages the drive shaft 31, it can also realize pure electric mode, E-CVT mode, hybrid mode, and engine 11 direct drive mode.

[0148] Therefore, the combination and matching relationship between the components of the hybrid power system 100 in the second embodiment can form different driving modes as shown in Table 2 above.

[0149] like Figure 3 As shown, the hybrid power system 100 of the third embodiment includes: a housing 10, an engine 11, a generator 12, a drive motor 13, a drive motor shaft 14, a power input gear 15, a first planetary gear mechanism 20, a first sun gear 21, a first planetary gear 22, a first planetary carrier 23, a first ring gear 24, a first connecting shaft 25, a second connecting shaft 26, a transmission mechanism 30, a transmission shaft 31, a power output mechanism 40, a second sun gear 43, a second planetary gear 44, a second planetary carrier 45, a second ring gear 46, a first coupling mechanism 50, a second coupling mechanism 60, and a third coupling mechanism 70. The first coupling mechanism 50 has a fourth coupling position 51, a fifth coupling position 52, and a sixth coupling position 53.

[0150] The first sun gear 21 has a first connecting shaft 25, and a first coupling mechanism 50 is disposed on the first connecting shaft 25 and connected to the first sun gear 21. The generator 12 is drivenly connected to the first connecting shaft 25, and the first coupling mechanism 50 is disposed between the generator 12 and the first planetary gear mechanism 20. The engine 11 is disposed on the same side of the first planetary gear mechanism 20, the generator 12, and the first coupling mechanism 50, and is drivenly connected to the second connecting shaft 26. The first connecting shaft 25 and the second connecting shaft 26 are parallel and spaced apart.

[0151] The transmission mechanism 30 comprises a transmission shaft 31, the second coupling mechanism 60 is arranged on the transmission shaft 31 of the transmission mechanism 30, the second coupling mechanism 60 is arranged between the first planetary gear mechanism 20 and the driving motor 13, and the transmission shaft 31 is arranged opposite to the second connecting shaft 26. The power output mechanism 40 comprises a second sun gear 43, a second planetary gear 44, a second planetary carrier 45 and a second ring gear 46, the second planetary gear 44 is engaged between the second sun gear 43 and the second ring gear 46, and the second planetary gear 44 is rotatably arranged on the second planetary carrier 45, the second planetary carrier 45 is configured as a power output end, the transmission shaft 31 and the second sun gear 43 are in transmission connection, and the third coupling mechanism 70 is arranged on the second ring gear 46, and the third coupling mechanism 70 selectively couples the transmission shaft 31 or the housing 10.

[0152] The first coupling mechanism 50 has a fourth coupling position 51, a fifth coupling position 52 and a sixth coupling position 53, when the first coupling mechanism 50 is in the fourth coupling position 51, the first coupling mechanism 50 couples the first sun gear 21 and the housing 10, the power of the engine 11 can be transmitted to the vehicle through the first planetary carrier 23 to realize the driving mode of the engine 11 alone driving (engine 11 direct drive mode), or the power of the driving motor 13 can be transmitted to the vehicle through the second planetary carrier 45 to realize the driving mode of the driving motor 13 alone (single motor pure electric mode).

[0153] When the first coupling mechanism 50 is in the fifth coupling position 52, the first coupling mechanism 50 couples the first sun gear 21 and the transmission mechanism 30, and the driving mode of the generator 12 and the driving motor 13 driving the vehicle at the same time can be realized (such as the double motor pure electric mode of the generator 12 and the driving motor 13 driving at the same time).

[0154] When the first coupling mechanism 50 is in the sixth coupling position 53, the first coupling mechanism 50 is disconnected with the housing 10 and the transmission mechanism 30, and the driving mode of the engine 11 and the generator 12 driving together can be realized (such as E-CVT mode), or the driving mode of the engine 11, the generator 12 and the driving motor 13 driving together (hybrid mode) can be realized.

[0155] The second coupling mechanism 60 selectively couples or disconnects the transmission mechanism 30 and the first ring gear 24, when the second coupling mechanism 60 couples the transmission mechanism 30 and the first ring gear 24, the driving mode of the engine 11 and the generator 12 driving together (such as E-CVT mode), or the driving mode of the engine 11, the generator 12 and the driving motor 13 driving together (hybrid mode), or the engine 11 direct drive mode of the engine 11 alone driving the vehicle can be realized.

[0156] When the second coupling mechanism 60 disconnects the transmission mechanism 30 and the first ring gear 24, a driving mode in which the generator 12 and the driving motor 13 simultaneously drive the vehicle (for example, a dual-motor pure electric mode in which the generator 12 and the driving motor 13 simultaneously drive) can be implemented, or a single-motor pure electric mode in which the driving motor 13 solely drives the vehicle can be implemented.

[0157] The third coupling mechanism 70 is arranged on the second ring gear 46, and selectively couples the transmission shaft 31 or the housing 10. When the third coupling mechanism 70 couples the transmission shaft 31, the pure electric mode, the E-CVT mode, the hybrid mode, and the engine 11 direct drive mode can be implemented. When the third coupling mechanism 70 disconnects the transmission shaft 31, the pure electric mode, the E-CVT mode, the hybrid mode, and the engine 11 direct drive mode can also be implemented.

[0158] Therefore, the coupling matching relationship between the components of the hybrid power system 100 of the third embodiment can form the driving modes of different gears as shown in Table 3.
