[0072] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0073] Refer to Figures 1 to 7 As shown, for the convenience of introduction, the upper, lower, left, right, front, and rear orientations are adopted in the corresponding drawings to facilitate the introduction of the relative positional relationship between the various parts in the present application, and it should not be construed as a limitation on the absolute position.

[0074] Moreover, in this application, the radial direction corresponds to the front-back direction, and the axial direction corresponds to the left-right direction. Similarly, here the indication of the radial direction as the front-back direction is only for the convenience of introducing the specific embodiments of this application, and there is no absolute corresponding relationship between the radial direction and the front-back direction. Similarly, there is no absolute corresponding relationship between the axial direction and the left-right direction either.

[0075] The axial direction and the radial direction of this application are also only for expressing relative positional relationships. They only indicate approximate orientations, rather than absolute geometric relationships.

[0076] According to the first aspect of this application, with reference to Figure 1 and Figure 7 , a hybrid power system is provided. This hybrid power system has a parallel mode, a series mode, a pure electric mode, a direct drive mode, and a parking power generation mode, and the mode can be selected according to actual usage requirements.

[0077] With reference to Figures 1 to 7 , the hybrid power system includes an engine 110, a motor, a differential 150, a storage battery (not shown in the figure), and a wheel (not shown in the figure). Among them, the wheel is connected to the differential 150, and the second motor 130 and the first motor 120 respectively provide power to the differential 150 to drive the wheel to rotate, and the storage battery is electrically connected to the motor.

[0078] The engine 110 includes an output shaft 111, a cylinder block 112, and an output axis 11a, and the motor has a motor shaft and a rotation axis 1a.

[0079] Among them, the output shaft 111 rotates around the output axis 11a, and the motor shaft rotates around the rotation axis 1a.

[0080] By arranging the motor shaft on one side of the output shaft 111 and making the main projection of the engine 110 on the output axis 11a overlap with the sub-projection of the motor on the output axis 11a, the effect of arranging the engine 110 and the motor radially along the engine 110 can be achieved.

[0081] By arranging the motor and the engine 110 radially along the engine, the motor and the engine 110 are arranged more compactly, and the main projection of the engine 110 on the output axis 11a overlaps with the sub-projection of the motor on the output axis 11a, which can effectively save the axial dimension occupied by the hybrid power system. Without a large degree of adjustment of the suspension structure, the hybrid power system can be arranged on the vehicle, and the hybrid power system of this application can be flexibly arranged radially in various suspensions, which helps to apply the hybrid power system of the application to various vehicle architecture platforms and improve the degree of platform generalization.

[0082] Define the orthographic projection of the engine 110 on the output axis 11a as the main projection, and define the orthographic projection of the motor on the output axis 11a as the sub - projection. In some embodiments, the main projection and the sub - projection partially overlap or completely overlap.

[0083] Specifically, the overlapping ratio of the main projection and the sub - projection can be set to 0.9, that is, 90% of the sub - projection completely falls within the orthographic projection.

[0084] Alternatively, the overlapping ratio of the main projection and the sub - projection can be set to 1, that is, the sub - projection completely falls within the main projection.

[0085] In some embodiments, referring to Figure 1 and Figure 2 , the motor includes a first motor 120.

[0086] Among them, the first motor 120 has a first motor shaft 121 that rotates around a first rotation axis 12a. The first motor shaft 121 is located on one side of the output shaft 111, achieving the effect of arranging the first motor 120 radially along the engine 110.

[0087] In some embodiments, the first rotation axis 12a is set parallel to the output axis 11a. By setting the first rotation axis 12a parallel to the output axis 11a, the power transmission can be better performed.

[0088] Specifically, the first motor 120 is configured as a drive motor and can provide electric drive for the vehicle.

[0089] In some embodiments, referring to Figure 1 and Figure 2 , the motor further includes a second motor 130.

[0090] Among them, the second motor 130 has a second motor shaft 131 that rotates around a second rotation axis 13a. The second motor shaft 131 is located on one side of the output shaft 111, achieving the effect of arranging the second motor 130 radially along the engine 110, and further reducing the axial dimension occupied by the engine and the motor.

[0091] In some embodiments, referring to Figure 1 , the second rotation axis 13a can be set parallel to the output axis 11a to facilitate the arrangement of the second motor 130.

[0092] Specifically, the second motor 130 is configured as a generator and can provide power for the vehicle or reserve power to avoid waste of energy.

[0093] In some embodiments, referring to Figure 1 and Figure 2, the first motor shaft 121 and the second motor shaft 131 can be located on the same side of the output shaft 111, further improving the degree of integration of the first motor 120 and the second motor 130 on one side of the engine 110, so as to further reduce the axial dimension occupied by the motors, and thus reduce the axial dimension occupied by the overall engine 110, the first motor 120 and the second motor 130.

[0094] In some embodiments, the first motor shaft 121 and the second motor shaft 131 can be movably connected, which is convenient for arranging the first motor 120 and the second motor 130, so as to further integrate the first motor 120 and the second motor 130 onto the engine.

[0095] In some embodiments, referring to Figure 1 , the first motor shaft 121 has a hollow cavity, and at least a part of the second motor shaft 131 penetrates through the hollow cavity.

[0096] Specifically, the second motor shaft 131 of the second motor 130 can be set as a solid shaft, the first motor 120 uses a hollow shaft motor, the second motor shaft 131 of the second motor 130 passes through the first motor shaft 121 of the hollow shaft motor, and there is a gap between the outer wall surface of the second motor shaft 131 and the inner wall surface of the first motor shaft 121. When the two motor shafts rotate, they do not interfere with each other's rotation.

[0097] In order to further improve the integration degree of the motors, in some embodiments, the first rotation axis 12a and the second rotation axis 13a are collinear, so that the first motor shaft 121 and the second motor shaft 131 are coaxially arranged.

[0098] In some embodiments, the output shaft 111 is selectively connected or disconnected from the second motor shaft 131 for power transmission.

[0099] Among them, when the engine 110 is in transmission connection with the second motor shaft 131, the engine 110 can supply power to the second motor 130, so that the second motor 130 rotates to supply power to the storage battery, so that the storage battery is charged or supplies power to the first motor 120 through the storage battery.

[0100] It should be noted that, referring to Figure 6 , when the engine 110 drives the second motor 130 to rotate to supply power to the storage battery, so that the storage battery is charged, the hybrid power system is in the parking power generation mode at this time.

[0101] Referring to Figure 5 , when the engine 110 supplies power to the storage battery through the second motor 130 to supply power to the first motor 120, the first motor 120 can drive to provide power to the differential 150, so as to provide a rotational force to the wheels. At this time, the hybrid power system is in the series mode.

[0102] In the parking power generation mode and the series mode, the engine 110 does not directly supply power to the differential 150.

[0103] In some embodiments, the hybrid power system further includes a power generation transmission member 140, including a first transmission portion 141 and a second transmission portion 142 that are transmission-connected.

[0104] Wherein, the output shaft 111 is selectively connected or disconnected from the second motor shaft 131 through the first transmission portion 141 and the second transmission portion 142.

[0105] When the output shaft 111 is transmission-connected to the second motor shaft 131 through the first transmission portion 141 and the second transmission portion 142, at this time, the engine 110 remains connected to the second motor 130, so that the hybrid power system is in the parking power generation mode or the series mode.

[0106] In some embodiments, the differential 150 in the hybrid power system includes a first input shaft 151.

[0107] The output shaft 111 of the engine 110 and the first motor shaft 121 of the first motor 120 are selectively transmission-connected or disconnected from the first input shaft 151.

[0108] Wherein, both the output shaft 111 of the engine 110 and the first motor shaft 121 of the first motor 120 can be transmission-connected to the first input shaft 151, or either one of the output shaft 111 of the engine 110 and the first motor shaft 121 of the first motor 120 can be connected to the first input shaft 151.

[0109] When both the output shaft 111 of the engine 110 and the first motor shaft 121 of the first motor 120 are transmission-connected to the first input shaft 151, at this time, the hybrid power system is in the parallel mode, and the engine 110 and the first motor 120 supply power to the differential 150 simultaneously.

[0110] Reference Figure 7 , when the output shaft 111 of the engine 110 is transmission-connected to the first motor shaft 121, and the first motor shaft 121 of the first motor 120 is disconnected from the first input shaft 151, at this time, the hybrid power system is in the direct drive mode, and the engine 110 alone directly supplies power to the differential 150.

[0111] Reference Figure 3, when the output shaft 111 of the engine 110 is disconnected from the first motor shaft 121 and the first motor shaft 121 of the first motor 120 is in transmission connection with the first input shaft 151, and when the first motor shaft 121 is disconnected from the first input shaft 151, the first motor 120 is used alone to provide power to the differential 150. At this time, the hybrid system is in pure electric mode.

[0112] In some embodiments, the hybrid system further includes a clutch 160. The clutch 160 includes a second input shaft 161 and a third input shaft 162 that are in transmission connection. The second input shaft 161 and the third input shaft 162 are used to selectively connect or disconnect the output shaft 111 from the first input shaft 151 in transmission.

[0113] Wherein, the third input shaft 162 and the second input shaft 161 are located between the output shaft 111 and the first input shaft 151.

[0114] In some examples, when the output shaft 111 is in transmission connection with the first input shaft 151 through the third input shaft 162 and the second input shaft 161, the effect of connecting the engine 110 to the differential 150 through the clutch 160 is achieved.

[0115] That is, the output shaft 111 is in transmission connection with the third input shaft 162, the third input shaft 162 is in transmission connection with the second input shaft 161, and the second input shaft 161 is in transmission connection with the first input shaft 151, achieving the effect of connecting the engine 110 to the differential 150 through the clutch 160.

[0116] When disconnecting the connection between the output shaft 111 and the third input shaft 162, the connection between the third input shaft 162 and the second input shaft 161, and the connection between the second input shaft 161 and the first input shaft 151, the disconnection of the engine 110, the clutch 160 and the differential 150 is achieved.

[0117] In some embodiments, a direct drive transmission member 170 is further included. The direct drive transmission member 170 is disposed between the clutch 160 and the differential 150. The direct drive transmission member 170 includes a third transmission portion 171 and a fourth transmission portion 172 that are in transmission connection.

[0118] Wherein, the third transmission portion 171 is in transmission connection with the second input shaft 161, and the fourth transmission portion 172 is selectively in transmission connection with or disconnected from the first input shaft 151.

[0119] In some embodiments, an electric drive transmission member 180 is further included, which is disposed between the differential 150 and the first motor 120, and is used to disconnect or connect the differential 150 from the first motor 120, achieving the effect of disconnecting the power transmission from the first motor 120 to the differential 150 or providing power from the first motor 120 to the differential 150.

[0120] The electric drive member 180 includes a fifth drive portion 181 and a sixth drive portion 182 that are drivingly connected, wherein the fifth drive portion 181 is selectively drivingly connected to or disconnected from the first motor shaft 121, and the sixth drive portion 182 is selectively drivingly connected to or disconnected from the first input shaft 151.

[0121] When the fifth drive portion 181 remains drivingly connected to the first motor shaft 121 and the sixth drive portion 182 remains drivingly connected to the first input shaft 151, the first motor 120 participates in the power transmission to the differential 150.

[0122] Alternatively, the engine 110 is disconnected from the clutch 160, the direct drive member 170, and the differential 150, such that the electric drive member 180 remains connected to the differential 150, and only the first motor 120 is used to provide power to the differential 150. At this time, the hybrid power system is in the pure electric mode.

[0123] In some embodiments, at least one of the electric drive member 180, the direct drive member 170, and the electric drive member 180 can be configured as a gear structure. The gear structure can be a spur gear or a helical gear, and the specific type is selected according to the actual application. Different numbers of gear meshing pairs are used to achieve multi-gear drive, and the arrangement position of the gear structure can be flexibly adjusted according to requirements.

[0124] The first drive portion 141, the second drive portion 142, the third drive portion 171, the fourth drive portion 172, and the fifth drive portion 181 all use spur gears.

[0125] In some embodiments, the engine 110 includes a cylinder block 112, the first motor 120 includes a first motor body 122, and the second motor 130 includes a second motor body 132. The first motor body 122 and the second motor body 132 are fixedly connected to the cylinder block 112.

[0126] That is, at least one of the first motor body 122 and the second motor body 132 is integrally fixed to the cylinder block 112 of the engine 110.

[0127] The orthographic projections of the first motor body 122 and the second motor body 132 on the output axis 11a completely fall within the orthographic projection of the cylinder block 112 on the output axis 11a, while the orthographic projections of the first motor shaft 121 and the second motor shaft 131 on the output axis 11a partially fall within the orthographic projection of the cylinder block 112 on the output axis 11a and partially do not fall within the orthographic projection of the cylinder block 112 on the output axis 11a.

[0128] In some examples, both the first motor body 122 and the second motor body 132 are integrated onto the cylinder block 112. The ways of integrally fixing the first motor body 122 and the second motor body 132 to the cylinder block 112 are common connection and fixing methods in the prior art, and will not be elaborated here.

[0129] In some embodiments, the storage battery is electrically connected between the second motor 130 and the first motor 120.

[0130] In this embodiment, when the engine 110 drives the second motor 130 to rotate, so that the hybrid power system is in the parking power generation mode, the storage battery is charged.

[0131] In this embodiment, the storage battery can be used alone to supply power to the first motor 120, so that the hybrid power system is in the pure electric mode.

[0132] In this embodiment, the engine 110 can be used alone to drive the differential 150, so that the hybrid power system is in the direct drive mode.

[0133] In this embodiment, the engine 110 can be used to drive the second motor 130, so that the second motor 130 supplies power to the first motor 120, and the first motor 120 provides power to the differential 150. At this time, the hybrid power system is in the series mode.

The vehicle includes the above hybrid power system. Therefore, it has all the beneficial effects of the above hybrid power system, and will not be elaborated here in the present application.

[0135] Moreover, when the vehicle of the present application is arranged, the longitudinal dimension occupied by the hybrid power system is small, which is convenient for the overall vehicle arrangement.
