[0036] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0037] Reference below Figures 1-4 A hybrid power system 10 according to an embodiment of the present invention is described, including: a front axle power group 100 , a first electric motor 200 , a first transmission device 300 , a second transmission device 400 , a drive coupling device 500 and a disconnection device 600 .

[0038] Specifically, the input end of the first transmission device 300 is transmission-connected to the output end of the front axle power group 100; the input end of the second transmission device 400 is transmission-connected to the output end of the first motor 200; one end of the drive coupling device 500 is transmission-connected to the output end of the first transmission device 300, and the other end of the drive coupling device 500 is transmission-connected to the output end of the second transmission device 400, and the drive coupling device 500 is configured to couple the driving force of the front axle power group 100 and the driving force of the first motor 200; the disconnection coupling device 600 is arranged between the drive coupling device 500 and the first transmission device 300, and / or the disconnection coupling device 600 is arranged between the drive coupling device 500 and the second transmission device 400, and the disconnection coupling device 600 selectively connects the drive coupling device 500 with one of the first transmission device 300 and the second transmission device 400.

[0039] It should be noted that the hybrid power system 10 provided in the present application is suitable for being constructed in an off-road vehicle so that the power output of the vehicle can meet the driving requirements of the vehicle, so that the power output of the vehicle can be stronger.

[0040] Specifically, the hybrid system 10 is suitable for including a front axle power group 100, a first electric motor 200, a first transmission device 300, a second transmission device 400, a drive coupling device 500 and a disconnection device 600. The front axle power group 100 is suitable for providing driving force, the first electric motor 200 is suitable for providing motor power, and the power provided by the engine is suitable for being transmitted through the first transmission device 300 and finally transmitted to the drive coupling device 500 for coupling. At the same time, the power provided by the first electric motor 200 is suitable for being transmitted through the second transmission device 400 and finally transmitted to the other side of the drive coupling device 500 for coupling, so that the hybrid system 10 can transmit the power after coupling to realize the power output of the hybrid system 10.

[0041] Moreover, a disconnection coupling device 600 is adapted to be provided on both sides of the drive coupling device 500. The disconnection coupling device 600 is adapted to be coupled or disconnected according to control to realize power transmission or separate power transmission, so that the hybrid system 10 can provide different power outputs according to demand, so that the output performance of the hybrid system 10 can meet the driving requirements of the vehicle, so that the use experience of the vehicle equipped with the hybrid system 10 can be improved.

[0042] Specifically, the input end of the first transmission device 300 is transmission-connected to the engine and the output end of the second electric motor of the front axle power unit 100, allowing the power provided by the front axle power unit 100 to be adjusted and transmitted through the first transmission device 300, so that the power transmitted through the first transmission device 300 can meet the power requirements of the vehicle. Similarly, the input end of the second transmission device 400 is transmission-connected to the output end of the first electric motor 200, allowing the power provided by the first electric motor 200 to be transmitted and adjusted through the second transmission device 400, so that the power transmitted through the second transmission device 400 can meet the power requirements of the vehicle. The power transmitted through the first transmission device 300 and the power transmitted through the second transmission device 400 can be transmitted to the drive coupling device 500, so that the drive coupling device 500 can couple the power transmitted to the drive coupling device 500, so that the power output of the hybrid system 10 is suitable for meeting the driving requirements of the vehicle. Moreover, by providing a disconnection and coupling device 600 on both sides of the drive coupling device 500, the power transmission and separation of the first transmission device 300 and the second transmission device 400 can be realized by controlling the disconnection and coupling of the disconnection and coupling device 600, that is, the coupling or disconnection between the front axle power and the rear axle power, thereby realizing the two-wheel drive or four-wheel drive mode of the vehicle, providing different power output driving according to road conditions, so that the vehicle equipped with the hybrid power system 10 has higher driving performance to meet the use requirements.

[0043] According to the hybrid power system 10 of the embodiment of the present invention, a disconnection and coupling device 600 is provided in the hybrid power system 10, so that the disconnection and coupling device 600 can be disconnected and coupled according to control, so that power can be selectively transmitted to the drive coupling device 500 for coupling and output according to demand, or power can be directly transmitted to the front axle and the rear axle for output according to demand, so that the hybrid power system 10 has multiple output modes, so that the vehicle can select different power output modes according to demand during driving, and can provide higher output performance after coupling, thereby improving the driving performance of the vehicle.

[0044] In some embodiments, the disconnection and coupling device 600 includes: a first disconnection and coupling component 610 and a second disconnection and coupling component 620, and the first disconnection and coupling component 610 and the second disconnection and coupling component 620 both include: a first connection part 630 and a second connection part 640, the first connection part 630 is connected to the drive coupling device 500; the second connection part 640 is provided at the output end of the first transmission device 300 or the second connection part 640 is provided at the output end of the second transmission device 400, and the first connection part 630 and the second connection part 640 are selectively transmitted and connected.

[0045] Specifically, the disconnect coupling device 600 is adapted to include a first disconnect coupling assembly 610 and a second disconnect coupling assembly 620. The first disconnect coupling assembly 610 is disposed between the drive coupling device 500 and the first transmission device 300, and the second disconnect coupling assembly 620 is disposed between the drive coupling device 500 and the second transmission device 400. This allows the disconnect coupling device 600 to selectively disconnect at least one of the first disconnect coupling assembly 610 and the second disconnect coupling assembly 620 during use, enabling power to be disconnected or coupled as needed, thereby reducing unnecessary power loss in different modes of the hybrid system 10 and improving the vehicle's driving performance. For example, when the hybrid system 10 only requires the first transmission device or the second transmission device to operate, that is, when the vehicle is in a front-axle two-wheel drive mode or a rear-axle two-wheel drive mode, the first disconnect coupling assembly 610 or the second disconnect coupling assembly 620 can be selectively disconnected to reduce drag on the front or rear axles by the rear axle wheels or the front axle wheels, and reduce wear on the drive coupling device 500. Furthermore, the selective use of the first disconnecting and coupling assembly 610 and the second disconnecting and coupling assembly 620 for disconnection and coupling allows the first disconnecting and coupling assembly 610 and the second disconnecting and coupling assembly 620 to have more reliable performance and a longer service life to meet the needs of the user. Furthermore, during the specific use of the disconnecting and coupling device 600, the first disconnecting and coupling assembly 610 or the second disconnecting and coupling assembly 620 can be selectively provided to meet the design and use of the hybrid system 10, thereby reducing the structural cost of the hybrid system 10.

[0046] Furthermore, during the specific design of the disconnect coupling device 600, it is suitable to make the structural designs of the first disconnect coupling assembly 610 and the second disconnect coupling assembly 620 similar to each other, so as to facilitate production and reduce production costs. Specifically, the first disconnect coupling assembly 610 and the second disconnect coupling assembly 620 each include: a first connecting portion 630 and a second connecting portion 640. The first connecting portion 630 is adapted to be correspondingly disposed on the drive coupling device 500, and the second connecting portion 640 is selectively connected to the first connecting portion 630 via a transmission connection, so that the power transmitted to the second connecting portion 640 is suitable for transmission transmission to the drive coupling device 500 for coupling, thereby forming different power output modes of the subsequent hybrid system 10.

[0047] In some embodiments, the drive coupling device 500 includes a first coupling portion 510 and a second coupling portion 520. The first coupling portion 510 is disposed at the output end of the first transmission device 300; the second coupling portion 520 is disposed at the output end of the second transmission device 400. The first coupling portion 510 and the second coupling portion 520 engage and transmit power. In other words, the drive coupling device 500 is adapted to include the first coupling portion 510 and the second coupling portion 520. The power transmitted to the first coupling portion 510 via the first transmission device 300 is adapted to be coupled with the power transmitted to the second coupling portion 520 via the second transmission device 400. This allows the front axle power unit 100 to be coupled with the power of the first electric motor 200 when the hybrid system 10 is required to provide a greater power output, thereby coupling the power output of the hybrid system 10 to achieve a greater power output to meet the vehicle's needs.

[0048] In some specific embodiments, the first coupling portion 510 and the second coupling portion 520 are both spiral bevel gears, and the first coupling portion 510 and the second coupling portion 520 are coupled perpendicularly to each other. It is understood that by configuring the first coupling portion 510 and the second coupling portion 520 as spiral bevel gears, the first coupling portion 510 and the second coupling portion 520 can have more reliable performance during the coupling process, and can more reliably couple power, thereby allowing the hybrid system 10 to have higher power output to meet driving needs.

[0049] In some embodiments, the first transmission device 300 includes: a planetary transmission assembly 310, a first transmission shaft 320, a plurality of gear members 330 and a second transmission shaft 340, the planetary transmission assembly 310 is respectively connected to the output ends of the engine 120 and the second motor 110, the first transmission shaft 320 is connected to the planetary transmission assembly 310, and at least part of the gear part is arranged on the first transmission shaft 320; the second transmission shaft 340 and the first transmission shaft 320 are arranged in parallel at intervals, at least another part of the gear members 330 are arranged on the second transmission shaft 340, and the output end of the second transmission shaft 340 is connected to the drive coupling device 500.

[0050] That is to say, in the specific use process, the first transmission device 300 is suitable for including a planetary transmission assembly 310, a first transmission shaft 320, a plurality of gear members 330 and a second transmission shaft 340, and the power of the engine 120 and / or the second electric motor 110 is suitable for being transmitted to the planetary transmission assembly 310, and the engine 120 and / or the second electric motor 110 are selectively allowed to output power so that the power is integrated on the planetary transmission assembly 310, and then the integrated power of the planetary transmission assembly 310 is transmitted to the first transmission shaft 320, and is transmitted through one of the plurality of gear members 330 to transmit the power to the second transmission shaft 340, and then the power is suitable for being transmitted to the front axle, so that the front axle equipped with the first transmission device 300 can realize the engine direct drive mode, pure electric mode, ECVT mode and hybrid mode, or the front axle power is transmitted to the drive coupling device 500 and power-coupled with the rear axle equipped with the second transmission device 400, so as to realize different power output modes of the hybrid system 10, such as pure electric four-wheel drive and hybrid four-wheel drive. Especially when the vehicle is in the feeding state, since the front axle has the ECVT mode, the front axle can generate electricity while driving, provide electrical energy for the first electric motor 200, and perform the hybrid four-wheel drive power output mode.

[0051] In some embodiments, the plurality of gear components 330 include: a first gear portion 331, a second gear portion 332 and a first synchronizer 335, the first gear portion 331 includes two first gears 3311 meshing with each other, one first gear 3311 is provided on the first transmission shaft 320, and the other first gear 3311 is provided on the second transmission shaft 340; the second gear portion 332 includes two second gears 3321 meshing with each other, the transmission speed ratio of the second gear portion is different from the transmission speed ratio of the first gear portion, one second gear 3321 is provided on the first transmission shaft 320, and the other second gear 3321 is provided on the second transmission shaft 340; the first synchronizer 335 selectively controls the first gear portion 331 and the second gear portion 332 to be used in combination.

[0052] Specifically, the plurality of shift members 330 may include a first shift portion 331, a second shift portion 332, and a first synchronizer 335. The first shift portion 331 and the second shift portion 332 may be connected between the first transmission shaft 320 and the second transmission shaft 340 to achieve power transmission between the first transmission shaft 320 and the second transmission shaft 340. Due to the different transmission speed ratios of the first shift portion 331 and the second shift portion 332, the first shift portion 331 and the second shift portion 332 may achieve power transmission at different gears, thereby allowing the power transmitted by the first transmission device 300 to have different output torques to meet output requirements. During the selection and use of different gears, the first synchronizer 335 may be selectively selected to achieve different gear selections, thereby achieving different power output modes of the first transmission device 300.

[0053] In some embodiments, the multiple gear parts 330 also include: a torque increasing mechanism 334, which is transmission-connected to the second gear part 332, and the torque increasing mechanism 334 includes a sun gear, a planetary carrier and a ring gear. The sun gear is fixedly connected to the first transmission shaft 320, the ring gear is braked, and the planetary carrier is connected to the second gear 3321 provided on the first transmission shaft 320.

[0054] Thus, by providing the torque-boosting mechanism 334 on the second gear unit 332, the second gear unit 332 can generate greater torque during use, providing greater torque to facilitate vehicle escape when the vehicle is in muddy, mountainous, or climbing conditions. Specifically, the torque-boosting mechanism 334 includes a sun gear, a planetary carrier, and a ring gear. The use of a planetary gear mechanism for power transmission allows the second gear unit 332 to have a wider power transmission range, thereby generating greater torque to meet the needs of vehicle escape.

[0055] In some embodiments, the multiple gear components 330 also include: a third gear portion 333 and a second synchronizer 336, the third gear portion 333 includes three third gears 3331 meshed in sequence, one third gear 3331 is provided on the first transmission shaft 320, one third gear 3331 is provided on the second transmission shaft 340, and another third gear 3331 is meshed and connected between the other two third gears 3331, and the transmission direction of the third gear portion 333 is different from that of the first gear portion 331 and the second gear portion 332; the second synchronizer 336 and the first synchronizer 335 are arranged at intervals, and the second synchronizer 336 selectively controls the third gear portion 333 for combined use.

[0056] That is, by further providing a third gear portion 333 between the first transmission shaft 320 and the second transmission shaft 340 , the third gear portion 333 is adapted to have a transmission direction opposite to that of the first gear portion 331 and the second gear portion 332 to achieve reverse power output of the first transmission device.

[0057] In some embodiments, the first transmission device 300 also includes: a first auxiliary transmission shaft 350 and a first transmission pair 360, the first auxiliary transmission shaft 350 is arranged parallel to the first transmission shaft 320 and the second transmission shaft 340; the first transmission pair 360 includes first transmission gears 3601 that are meshed with each other, one first transmission gear 3601 is arranged on the second transmission shaft 340, and the other first transmission gear 3601 is arranged on the first auxiliary transmission shaft 350.

[0058] It is understood that during the configuration of the first transmission device 300, a first auxiliary transmission shaft 350 and a first transmission pair 360 may be selectively provided according to different vehicle conditions. Thus, during use, a first transmission pair 360 may be provided at the rear end of the second transmission shaft 340 to transmit power to the first auxiliary transmission shaft 350 through meshing of the first transmission pair 360, and then to the drive coupling device 500 via the first auxiliary transmission shaft 350. This allows the output position to be adjusted via the first transmission pair 360 and the first auxiliary transmission shaft 350, thereby facilitating the design and placement of the hybrid power system 10 within the vehicle and enhancing the convenience of its placement within the vehicle.

[0059] In some embodiments, the front axle power unit 100 includes: an engine 120 and a second electric motor 110, the engine 120 and the second electric motor 110 being coaxially arranged, and the second electric motor 110 selectively providing power or generating electricity. In other words, the front axle power unit 100 has two power output ends, namely the engine 120 and the second electric motor 110. When the engine 120 outputs a relatively abundant power or when the battery feed needs to be supplemented, it is suitable to divert part of the power to the second electric motor 110 so that the second electric motor 110 to which the power is transferred generates electricity, thereby allowing the second electric motor 110 to charge the battery. When the power is sufficient for pure electric drive, it is suitable for the second electric motor 110 to provide power to the first transmission device 300, which outputs the power to the front axle or couples it to the rear axle through the first transmission device 300 to meet the vehicle drive requirements.

Thus, during use, a second transmission pair 480 may be provided at the rear end of the fourth transmission shaft 430 to transmit power to the first auxiliary transmission shaft 350 through meshing of the second transmission pair 480, and then to the drive coupling device 500 via the second auxiliary transmission shaft 470.
