Referring to fig. 1 and 2, an embodiment of the invention provides a flying automobile 1000, and the flying automobile 1000 may be a land-air automobile, a triphibian automobile, or the like.
The flying car 1000 includes a rotor 200, wheels 300, and a drive system 100, with the rotor 200 and wheels 300 being connected to the drive system 100. The flying car 1000 can fly through the rotor 200 and can also land through the wheels 300.
The power unit 10 includes a motor generator 11, a battery pack 13, and an engine 15. The motor generator 11 is electrically connected to the battery pack 13, for example, the motor generator 11 may be electrically connected to the battery pack 13 through the power distribution unit 60, wherein the motor generator 11 and the power distribution unit 60 may be electrically connected by a high voltage cable, and the power distribution unit 60 and the battery pack 13 may be electrically connected by a high voltage cable.
The battery pack 13 may supply electric power to the motor generator 11, and the motor generator 11 may convert the electric power into mechanical power. The motor generator 11 may be in a state of providing driving force, and the motor generator 11 may output the driving force. For example, the driving shaft of the motor generator 11 is connected to the power transmission mechanism 30, the motor generator 11 in the state of supplying the driving force can drive the power transmission mechanism 30 to move. The motor generator 11 may also be in a power generation state, the motor generator 11 may output electric power, and the motor generator 11 in the power generation state may charge the battery pack 13.
The number of the motor generators 11 may be plural. In this application, the term "plurality" means greater than or equal to two. For example, the plurality of motor generators 11 may include a first motor generator 111 and a second motor generator 113, and both the first motor generator 111 and the second motor generator 113 are electrically connected to the battery pack 13. The first motor generator 111 and the second motor generator 113 are drivingly connected, and for example, the first motor generator 111 and the second motor generator 113 may be coaxially connected or may be connected in parallel. The drive shaft of the first motor generator 111 may be connected to the motor connecting portion 33. In this way, it is helpful to improve the safety of the flying vehicle 1000 in the flying state by the redundant backup of the motor generator 11.
The engine 15 can convert thermal energy into mechanical energy, for example, the engine 15 is connected to the power transmission mechanism 30, and the engine 15 can drive the power transmission mechanism 30 to move. The engine 15 may be a diesel engine, a gasoline engine, or other type. The engine 15 may be connected to the oil tank 80 through an oil pipe.
The engine connecting portion 31 is in transmission connection with the motor connecting portion 33, the rotor connecting portion 35 and the wheel connecting portion 37, so that the motor connecting portion 33, the rotor connecting portion 35 and the wheel connecting portion 37 can be driven to move by the movement of the engine connecting portion 31.
The motor connecting portion 33 is connected to a driving shaft of the motor generator 11, and the motor generator 11 can drive the motor connecting portion 33 to move. Motor connecting portion 33 is connected with rotor connecting portion 35, the transmission of wheel connecting portion 37 respectively, and then the motion of motor connecting portion 33 can drive rotor connecting portion 35 and the motion of wheel connecting portion 37. In addition, the movement of the motor connecting portion 33 can also move the motor generator 11, so that the motor generator 11 is in a power generating state.
The engine connection 31, motor connection 33, rotor connection 35, wheel connection 37, etc. may be gears, shafts, or other structures.
The connecting portions of the power transmission mechanism 30 may be directly connected in a transmission manner, or may be connected in a transmission manner through gears, shafts or other structures. For example, the motor connecting portion 31 and the motor connecting portion 33 may be connected coaxially or may be connected in parallel.

The engine clutch 50 may transmit the driving force of the engine 15 to the power transmission mechanism 30, for example, when the engine clutch 50 is in the engaged state. For example, when the engine clutch 50 is in the disengaged state, the engine clutch 50 does not transmit the driving force of the engine 15 to the power transmission mechanism 30. The engine clutch 50 may be an electromagnetic clutch, a hydraulic clutch, a friction clutch, or other types.
The wheel clutch 90 is connected between the wheel connecting portion 37 and the wheel 300, and the wheel clutch 90 can selectively transmit or disconnect the driving force of the power transmission mechanism 30 to the wheel 300. The wheel clutch 90 can transmit the driving force of the power transmission mechanism 30 to the wheels 300, for example, when the wheel clutch 90 is in the engaged state. For example, when the wheel clutch 90 is in the disengaged state, the wheel clutch 90 does not transmit the driving force of the power transmission mechanism 30 to the wheels 300. The wheel clutch 90 may be an electromagnetic clutch, a hydraulic clutch, a friction clutch, or other types.
In this way, the power device 10 can provide driving force for the rotor 200 and the wheel 300 through the motor generator 11, can also provide driving force for the rotor 200 and the wheel 300 through the engine 15, can also provide driving force for the rotor 200 and the wheel 300 through the motor generator 11 and the engine 15, and can also drive the motor generator 11 to generate electricity through the engine 15 and charge the battery pack 13, so that the diversity of the working modes of the driving system 100 is realized. In addition, since rotor 200 and wheel 300 share power plant 10, it helps to reduce the weight of drive system 100, reducing flight power requirements. In addition, the driving system 100 adopts the engine 15 and the motor generator 11 to provide power, which is beneficial to realizing the power backup between the engine 15 and the motor generator 11, and compared with a pure electric flying automobile, the driving range of the flying automobile 1000 in the flying state and the driving range in the land state can be greatly increased, and the safety of the flying automobile 1000 is improved.
For example, when rotor clutch 70 is engaged, rotor clutch 70 may transmit a driving force from rotor transmission 20 to rotor 200, which in turn may rotate rotor 200.
For example, when rotor clutch 70 is in the off state, rotor clutch 70 does not transmit the driving force of rotor transmission mechanism 20 to rotor 200, and rotor 200 is not driven by rotor transmission mechanism 20. In this manner, it helps to avoid the rotor 200 from idling, which in turn helps to reduce power consumption of the power plant 10.
In other embodiments, rotor drive mechanism 20 and rotor clutch 70 may be arranged in other locations to further reduce power losses of power plant 10. For example, rotor drive mechanism 20 may be coupled to rotor 200, and rotor clutch 70 may be coupled between rotor attachment portion 35 and rotor drive mechanism 20, rotor clutch 70 selectively transmitting or decoupling drive from power transmission mechanism 30 to rotor drive mechanism 20.
For example, when rotor clutch 70 is engaged, rotor clutch 70 may transmit a driving force from power transmission 30 to rotor transmission 20, such that rotor transmission 20 may rotate rotor 200.
For example, when rotor clutch 70 is in the off state, rotor clutch 70 does not transmit the driving force of power transmission mechanism 30 to rotor transmission mechanism 20, and rotor transmission mechanism 20 does not move and does not drive rotor 200 to rotate, which helps to prevent structures such as rotor transmission mechanism 20 and rotor 200 from idling, and thus helps to further reduce the power loss of power plant 10.
In the case where rotor drive mechanism 20 includes rotor drive assembly 22 and rotor drive member 24, rotor clutch 70 may be coupled between rotor attachment portion 35 and rotor drive assembly 22, and rotor clutch 70 may selectively transmit or decouple drive from power transmission mechanism 30 to rotor drive assembly 22.
For example, when rotor clutch 70 is engaged, rotor clutch 70 may transmit a drive force from power transmission 30 to rotor drive assembly 22 such that rotor drive assembly 22 may be moved by rotor drive mechanism 20.
For example, when rotor clutch 70 is in the off state, rotor clutch 70 does not transmit the driving force of power transmission mechanism 30 to rotor drive assembly 22, and rotor drive assembly 22 does not move nor drives rotor drive member 24 to move, which helps to prevent structures such as rotor drive assembly 22, rotor drive member 24, and rotor 200 from idling, and thus helps to further reduce the power loss of power plant 10.
The driving system 100 may further include a wheel transmission mechanism 40, and the wheel transmission mechanism 40 is connected to the wheel connecting portion 37, so that the power transmission mechanism 30 can drive the wheel transmission mechanism 40 to move. The wheel clutch 90 may be connected between the wheel gear 40 and the wheel 300, and the wheel clutch 90 may selectively transmit or disconnect the driving force of the wheel gear 40 to the wheel 300.
For example, when the wheel clutch 90 is in the engaged state, the wheel clutch 90 may transmit the driving force from the wheel transmission mechanism 40 to the wheel 300, which in turn may rotate the wheel 300.
For example, when the wheel clutch 90 is in the disengaged state, the wheel clutch 90 does not transmit the driving force of the wheel transmission mechanism 40 to the wheel 300, and the wheel 300 is not driven by the wheel transmission mechanism 40. In this manner, wheel 300 is facilitated to be prevented from spinning, which in turn facilitates reducing power consumption of power plant 10.
In other embodiments, the wheel transmission 40 and the wheel clutch 90 may be arranged at other positions to further reduce the power loss of the power plant 10. For example, the wheel gear mechanism 40 may be connected to the wheel 300, and the wheel clutch 90 may be connected between the wheel connecting portion 37 and the wheel gear mechanism 40, the wheel clutch 90 selectively transmitting or disconnecting the driving force of the power transmission mechanism 30 to the wheel gear mechanism 40.
For example, when the wheel clutch 90 is in the engaged state, the wheel clutch 90 may transmit the driving force of the power transmission mechanism 30 to the wheel transmission mechanism 40 so that the wheel transmission mechanism 40 may rotate the wheel 300.
For example, when the wheel clutch 90 is in the off state, the wheel clutch 90 does not transmit the driving force of the power transmission mechanism 30 to the wheel transmission mechanism 40, and at this time, the wheel transmission mechanism 40 does not move and does not drive the wheel 300 to rotate, which helps to prevent the wheel transmission mechanism 40 and the wheel 300 from idling, and further helps to reduce the power loss of the power plant 10.
The drive system 100 may further include a wheel final drive 42 and a wheel differential reducer 44, and the wheel final drive 42 and the wheel differential reducer 44 may be structured as the wheel transmission mechanism 40. The wheel final drive 42 may be connected to the wheel connecting portion 37, and the wheel differential reducer 44 may be connected to the wheel 300. The wheel clutch 90 may be connected between the wheel final drive 42 and the wheel differential reducer 44, and the wheel clutch 90 may selectively transmit or disconnect the driving force of the wheel final drive 42 to the wheel differential reducer 44.
For example, when the wheel clutch 90 is in the engaged state, the wheel clutch 90 may transmit the driving force from the wheel final drive 42 to the wheel differential reducer 44, so that the wheel differential reducer 44 may move the wheel 300.
For example, when the wheel clutch 90 is in the off state, the wheel clutch 90 does not transmit the driving force of the wheel final drive 42 to the wheel differential reducer 44, and at this time, the wheel differential reducer 44 does not rotate nor drive the wheels 300 to rotate, which helps to prevent the wheel differential reducer 44 and the wheels 300 from idling, and thus helps to reduce the power loss of the power plant 10.
Further, the wheel differential reducer 44 can adjust the driving force of the power unit 10, thereby achieving adjustment of the left and right wheels 300 to have different speeds. Since the wheel clutch 90 is connected between the wheel final drive 42 and the wheel differential reducer 44, the number of intermediate structures for transmitting the adjusted driving force from the wheel differential reducer 44 to the wheel 300 is reduced, which helps to avoid the power loss of the adjusted driving force from the wheel differential reducer 44 when the clutch is connected between the wheel differential reducer 44 and the wheel 300, thereby helping to ensure that the wheel differential reducer 44 provides the required driving force for the wheel 300, and effectively ensuring the reliability of the flying vehicle 1000 in the land state.
The drive system 100 may have different modes of operation in flight and in land travel of the flying vehicle 1000.
Referring to fig. 3, in the flight state, the operation mode of the driving system 100 may be a flight parallel mode. In this mode, rotor clutch 70 is engaged, wheel clutch 90 is disengaged, and engine clutch 50 is engaged; the motor generator 11 is in a state of providing driving force, and for example, both the first motor generator 111 and the second motor generator 113 are in a state of providing driving force. At this time, the engine 15 outputs power to the power transmission mechanism 30, the first motor generator 111 and the second motor generator 113 output power to the power transmission mechanism 30 together, and the power transmission mechanism 30 supplies power to the rotor 200 through the rotor transmission mechanism 20. Thus, the engine 15 and the motor generator 11 output power together, so that the power output by the power device 10 is larger, and the flying automobile 1000 is facilitated to adopt a flying parallel mode under the vertical take-off and landing working condition. Wherein the direction indicated by the thick arrow in fig. 3 is the direction of energy transmission.
Referring to fig. 4, in the flight state, if a single point failure occurs in the first motor generator 111 or the second motor generator 113, the operation mode of the driving system 100 may be a single point failure flight emergency mode. In this mode, the rotor clutch 70 is in the engaged state, the wheel clutch 90 is in the disengaged state, the engine clutch 50 is in the engaged state, and one of the first motor generator 111 and the second motor generator 113 is in the driving force providing state.

At this time, the motor generator 11 may output a larger power to the power transmission mechanism 30, and the power transmission mechanism 30 supplies power to the rotor 200 through the rotor transmission mechanism 20. In this manner, safe landing of the hovercar 1000 is facilitated. Furthermore, since the engine clutch 50 is in the disengaged state, it helps to prevent the engine 15 from idling, thereby helping to reduce power loss of the power plant 10. Wherein the direction indicated by the thick arrow in fig. 5 is the direction of energy transmission.
Referring to fig. 6, in a flight state, for example, in a flat flight condition, the flying vehicle 1000 has a smaller demand for power than in a vertical take-off and landing condition, and the operating mode of the driving system 100 may be a flight power generation mode. In this mode, rotor clutch 70 is engaged, wheel clutch 90 is disengaged, engine clutch 50 is engaged, and motor generator 11 generates electric power. At this time, the engine 15 outputs power to the power transmission mechanism 30, the power transmission mechanism 30 provides power for the rotor 200 through the rotor transmission mechanism 20 on one hand, and the power transmission mechanism 30 can drive the motor generator 11 to rotate by the redundant driving force of the engine 15 on the other hand, so that the motor generator 11 converts the mechanical energy into electric energy and charges the battery pack 13. In this manner, the driving range of the hovercar 1000 is increased. In fig. 6, the direction indicated by the thick arrow is the energy transmission direction.

In this mode, rotor clutch 70 is in the disengaged state, wheel clutch 90 is in the engaged state, engine clutch 50 is in the disengaged state, and motor generator 11 is in the driving force providing state. At this time, the motor generators 11 collectively output power to the power transmission mechanism 30, and the power transmission mechanism 30 powers the wheels 300 through the wheel transmission mechanism 40. In this manner, carbon emissions from the hovercar 1000 are facilitated to be reduced. Furthermore, since the engine clutch 50 is in the disengaged state, it helps to prevent the engine 15 from idling, thereby helping to reduce power loss of the power plant 10. In fig. 7, the direction indicated by the thick arrow is the energy transmission direction.
Referring to fig. 8, in the land state, the operation mode of the driving system 100 may be a land mixing mode. In this mode, rotor clutch 70 is in a disengaged state, wheel clutch 90 is in an engaged state, engine clutch 50 is in an engaged state, and motor generator 11 is in a driving force providing state. At this time, both the engine 15 and the motor generator 11 output power to the power transmission mechanism 30, and the power transmission mechanism 30 supplies power to the wheels 300 through the wheel transmission mechanism 40. Thus, the engine 15 and the motor generator 11 output power together, so that the power output by the power device 10 is larger, and the land-based hybrid mode adopted by the flying automobile 1000 under the working condition with larger power demand is facilitated. In fig. 8, the direction indicated by the thick arrow is the energy transmission direction.
Referring to fig. 9, in the land state, when the battery is low, the operation mode of the driving system 100 may be a land-based vehicle power generation mode. In this mode, rotor clutch 70 is in the off state, wheel clutch 90 is in the on state, engine clutch 50 is in the on state, and motor generator 11 is in the power generation state. At this time, the engine 15 outputs power to the power transmission mechanism 30, the power transmission mechanism 30 provides power to the wheels 300 through the wheel transmission mechanism 40 on one hand, and the power transmission mechanism 30 can drive the motor generator 11 to rotate by using the redundant driving force of the engine 15 on the other hand, so that the motor generator 11 converts the mechanical energy into electric energy and charges the battery pack 13. In this manner, the driving range of the hovercar 1000 is increased. In fig. 9, the direction indicated by the thick arrow is the energy transmission direction.

Rotor clutch 70 is coupled between rotor coupling portion 35 and rotor 200, and rotor clutch 70 selectively transmits or disconnects the driving force from power transmission mechanism 30 to rotor 200. The wheel clutch 90 is connected between the wheel connecting portion 37 and the wheel 300, and the wheel clutch 90 can selectively transmit or disconnect the driving force of the power transmission mechanism 30 to the wheel 300.

In addition, since rotor 200 and wheel 300 share power plant 10, it helps to reduce the weight of drive system 100, reducing flight power requirements. In addition, the driving system 100 adopts the engine 15 and the motor generator 11 to provide power, which is beneficial to realizing the power backup between the engine 15 and the motor generator 11, and compared with a pure electric flying automobile, the driving range of the flying automobile 1000 in the flying state and the driving range in the land state can be greatly increased, and the safety of the flying automobile 1000 is improved.
