[0002] As people's living standards continue to improve, energy conservation and environmental protection are becoming more and more widely concerned. Especially in the field of transmission technology, the use of a single engine to drive the oil pump faces problems such as high fuel consumption, heavy pollution and high cost of use; and the use of a single motor to drive the oil pump, many sites are not always able to provide high-voltage power supply. Therefore, in order to reasonably allocate power and reduce energy consumption, oil-electric hybrid drive can solve the above problems well.

[0003] However, in traditional new energy hybrid drive devices, the engine is connected to the motor rotor of the motor through a clutch, and the other end of the motor rotor is directly connected to the working device. In pure electric mode, the clutch is disengaged and the motor is working; when the pure engine is working, the clutch is connected to the power to drive the working device through the motor rotor; in hybrid mode, the clutch is connected, and the motor and the engine drive the working device to work at the same time. In this way, when the pure engine mode is used for driving, the motor rotor will rotate, especially for permanent magnet motors. At this time, three-phase AC high voltage will be generated on the three-phase line of the motor, which will cause safety hazards to personnel or motor controllers. This problem is particularly prominent because hybrid equipment often works in humid environments. Utility Model Content

[0041] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0042] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0043] Embodiment 1

[0044] See also Figure 1 and Figure 2 This embodiment provides an oil-electric hybrid driving device, which can realize switching between three driving modes: pure oil driving, pure electric driving and oil-electric hybrid driving.

[0045] In this embodiment, the oil-electric hybrid drive device includes a power transmission shaft 100, an oil drive module 200, an electric drive module 300 and a transmission module 400. The power transmission shaft 100 is used to connect an external working device 600 to transmit torque to the external working device 600. The oil drive module 200 can output torque under the drive of fuel, such as an engine 210. The electric drive module 300 can output torque under the drive of electric energy, and a motor 310 is provided in the electric drive module 300, and a rotor 311 of the motor 310 is connected to an output shaft 320.

[0046] The oil drive module 200 is connected to the power transmission shaft 100 through the clutch 500. The electric drive module 300 is arranged at one side of the oil drive module 200, and an output tooth 321 is provided on the output shaft 320 of the electric drive module 300.

[0047] Optionally, the clutch 500 may be a conventional diaphragm spring clutch assembly or a dog clutch.

[0048] The transmission module 400 includes a first transmission 410, a brake tooth 420 and a shift mechanism 430. The first transmission 410 is arranged between the electric drive module 300 and the oil drive module 200. The output end of the first transmission 410 is transmission-connected to the power transmission shaft 100. The input end of the first transmission 410 is provided with a transmission tooth 411. The brake tooth 420 is fixedly arranged on the housing 401 of the transmission module 400.

[0049] Please also read Figure 3 , Figure 4 and Figure 5, wherein the shift mechanism 430 includes a switchable first gear and a second gear. It can be understood that when the shift mechanism 430 is switched to the first gear, the output tooth 321 is connected to the transmission tooth 411 through the shift mechanism 430, and at this time, at least one of the oil drive module 200 and the electric drive module 300 can output torque to the power transmission shaft 100; when the shift mechanism 430 is switched to the second gear, the output tooth 321 is connected to the brake tooth 420 through the shift mechanism 430, and at this time, since the brake tooth 420 is set on the housing 401, the brake tooth 420 itself is in a braking state, so that the motor 310 in the electric drive module 300 in the second gear is not affected by the rotation of the power transmission shaft 100, that is, the electric drive module 300 will not rotate.

[0050] Further, the output tooth 321 is between the transmission tooth 411 and the brake tooth 420. The gear shifting mechanism 430 includes a slidable sleeve 431. Optionally, the gear shifting mode of the sleeve 431 can be a friction pair clutch mode or a tooth clutch mode.

[0051] See also Figure 1 and Figure 2 In this embodiment, the first transmission 410 includes a parallel gear reduction structure, which includes an input parallel gear 412 located at the input end of the first transmission 410 and an output parallel gear 413 located at the output end, and the input parallel gear 412 is in transmission connection with the output parallel gear 413. The input parallel gear 412 is rotatably arranged on the output shaft 320, the input parallel gear 412 is connected to the transmission tooth 411 and arranged coaxially, and the output parallel gear 413 is arranged on the power transmission shaft 100 and is locked with the power transmission shaft 100. The locking means that the relative rotation between the output parallel gear 413 and the power transmission shaft 100 is restricted, for example, by a flat key or a spline to achieve locking.

[0052] In some embodiments, a transition parallel gear 414 is further provided between the input parallel gear 412 and the output parallel gear 413, and the transition parallel gear 414 is used for transmission connection with the input parallel gear 412 and the output parallel gear 413. This is to avoid the input parallel gear 412 and the output parallel gear 413 being too large in span, which results in an increase in the design size, and makes the structure of the entire device more compact. Optionally, the transition parallel gear 414 can be one, two, or other numbers, which are not specifically limited in this embodiment.

[0053] In some embodiments, the output end of the electric drive module 300 is further provided with a second transmission 330, and the second transmission 330 is transmission-connected with the output shaft 320. In this way, the second transmission 330 is used to reduce the speed of the output shaft 320 and increase the torque, thereby improving the output torque of the output shaft 320.

[0054] Optionally, the second transmission 330 may be a planetary transmission reduction structure or a parallel shaft transmission reduction structure. It should be understood that the above is only an example and is not intended to limit the scope of protection of this application.

[0055] See also Figures 1 to 5 Thus, in the oil-electric hybrid drive device provided in this embodiment, the oil-electric hybrid drive device can realize the switching of three drive modes: pure oil drive, pure electric drive and oil-electric hybrid drive. In order to more clearly describe the technical solution of the present application, the pure oil drive mode, the pure electric drive mode and the hybrid drive mode are described below:

[0056] Please refer to Figure 2 and Figure 3 When the pure oil driving mode is required, the shift mechanism 430 switches to the second gear and controls the clutch 500 to engage. At this time, the output tooth 321 and the brake tooth 420 are connected through the shift mechanism 430. The oil drive module 200 can directly drive the power transmission shaft 100 to rotate. Since the brake tooth 420 is fixed on the housing 401, the output tooth 321 will be restricted from rotating by the brake tooth 420 under the action of the shift mechanism 430. That is to say, the electric drive module 300 will not rotate with the power transmission shaft 100.

[0057] Please refer to Figure 2 and Figure 4 When the pure electric driving mode is required, the shift mechanism 430 switches to the first gear. At this time, the output tooth 321 and the transmission tooth 411 are connected through the shift mechanism 430, and the clutch 500 is controlled to be separated, so that the electric drive module 300 can directly drive the power transmission shaft 100 to rotate.

[0058] Please refer to Figure 2 and Figure 5 When it is necessary to switch to the hybrid drive mode, the shift mechanism 430 switches to the first gear. At this time, the output tooth 321 and the transmission tooth 411 are connected through the shift mechanism 430, and the clutch 500 is controlled to engage. The oil drive module 200 and the electric drive module 300 can drive the power transmission shaft 100 at the same time.

[0059] Compared with the prior art, the oil-electric hybrid drive device provided in this embodiment can realize the switching of three drive modes: pure electric drive, pure oil drive and hybrid drive, so that the power output can be reasonably configured according to the working conditions to achieve the purpose of energy saving and emission reduction. At the same time, in the pure oil drive mode, the shift mechanism 430 can lock the electric drive module 300 to prevent the electric drive module 300 from rotating with the power transmission shaft 100. Therefore, even if the motor 310 in the electric drive module 300 is selected as a permanent magnet motor 310, the three-phase AC high voltage will not be generated on the three-phase line of the motor 310 at this time, thereby improving the safety of use and protecting the safety of the equipment.

[0060] In addition, when only pure oil drive is required, the motor 310 in the electric drive module 300 can be in a stationary state, which has a positive effect on reducing the overall NVH noise and reducing energy consumption.

[0061] Embodiment 2

[0062] See also Figure 1 and Figure 6 This embodiment provides an oil-electric hybrid drive device, which can realize three driving modes: pure oil drive, pure electric drive and oil-electric hybrid drive. This embodiment is an improvement made on the technical basis of the above embodiment 1. Compared with the above embodiment 1, the difference is:

[0063] In this embodiment, the oil-electric hybrid drive device further includes a power take-off 440, which is disposed on the housing 401 of the transmission module 400 and is transmission-connected to the output shaft 320. Thus, the power take-off 440 is directly driven by the motor 310 in the electric drive module 300, thereby providing power for other functional modules.

[0064] Please also read Figure 7 Furthermore, the shift mechanism 430 also includes a switchable third gear. When the shift mechanism 430 is switched to the third gear, the sleeve 431 of the shift mechanism 430 is located on the output tooth 321, and the output tooth 321 is disconnected from the transmission tooth 411 and the brake tooth 420. In this way, in the third gear, the clutch 500 can be in a disengaged state, the power transmission shaft 100 will not be driven by the electric drive module 300, and the electric drive module 300 only drives the power take-off 440 to work, entering the power take-off drive mode.

[0065] Please also read Figure 8 In some embodiments, the output end of the electric drive module 300 is further provided with a second transmission 330, and the second transmission 330 is transmission-connected with the output shaft 320. In this way, the second transmission 330 is used to reduce the speed and increase the torque of the output shaft 320, thereby improving the output torque of the output shaft 320. Compared with the electric drive module 300 directly driving the power take-off 440, the second transmission 330 can provide the torque output by the power take-off 440.

[0066] Optionally, the second transmission 330 may be a planetary transmission reduction structure or a parallel shaft transmission reduction structure. It should be understood that the above is only an example and is not intended to limit the scope of protection of this application.

[0070] Furthermore, this embodiment also provides a hybrid power device, which includes the driving pump provided in the fourth embodiment above, and the driving pump is an oil pump, which can be used in the hydraulic system of the hybrid power device.

[0071] In some embodiments, the motor 310 in the hybrid device is driven by an external high-voltage power supply, and there is no need to configure a storage battery for the motor 310, thereby reducing the weight of the entire device for easy transportation and avoiding the problem of increased energy consumption due to weight.
