[0002] As an indispensable part of the automobile system, the automobile power system refers to the system that transmits the power generated by the engine through a series of power transmissions and finally drives the car to move. The automobile power system mainly relies on the engine and clutch. The engine drives the rotation of the crankshaft through its own operation, and the crankshaft further drives the movement of the flywheel, thereby controlling the coordination between the flywheel and the clutch, and then transmits the power to the wheels through structures such as differentials and reducers.

[0003] The engine is part of the vehicle's power system, which mainly relies on fuel combustion to generate power to drive the vehicle. With the continuous development of new energy vehicles, extended-range new energy vehicles are becoming more and more popular among users, and the range extender is an indispensable part of the extended-range new energy vehicle power system. Its role is to indirectly provide power to the vehicle by charging the battery and increase the vehicle's mileage.

[0004] In the prior art, the automobile range extender is composed of a fuel generator, a generator, and an electronic control structure. Its power generation principle is to use a traditional piston engine to drive the generator to generate electricity. However, this type of range extender has the problems of low efficiency and integrated heat damage.

[0005] Therefore, the range extender of the prior art has the problems of low efficiency and integrated thermal damage. Utility Model Content

[0006] The utility model aims to solve the problems of low power generation efficiency and integrated heat damage in the range extender in the prior art.

[0009] The compressor blades of the compressor impeller are evenly arranged along the circumference of the rotating shaft, and a compressor flow channel is formed between the compressor blades. One end of the compressor flow channel is connected to the outside of the casing, and the other end extends into the casing and is connected to the combustion chamber of the turbine unit; and the compressor flow channel isolates the stator assembly from the combustion chamber.

[0010] By adopting the above technical solution, the range extender provided by the utility model includes a housing, a compressor unit and a turbine unit are coaxially arranged inside the housing, the compressor unit and the turbine unit are coaxially arranged, and when the turbine unit provides power, the turbine unit drives the compressor unit to rotate through the shaft to achieve power transmission. The housing also includes a power generation unit, wherein the rotor assembly of the power generation unit includes a magnetic component, and the magnetic component is arranged around the compressor unit so that the compressor impeller of the compressor unit rotates while driving the magnetic component to rotate, and the stator assembly is arranged around the magnetic component at intervals in the radial direction, and finally the magnetic component and the compressor impeller and the stator assembly rotate with each other to generate electricity.

[0011] Furthermore, a compressed air flow channel is formed between the compressor blades of the compressor impeller. The compressed air flow channel is a channel for gas to flow in. External air enters the interior of the casing through the compressed air flow channel and is connected with the combustion chamber of the turbine unit, providing a gas medium for the combustion inside the combustion chamber. The compressed air flow channel isolates the stator assembly from the combustion chamber. The high temperature generated by the combustion in the combustion chamber is isolated by the compressed air flow channel, thereby ensuring safe and stable operation of the stator assembly and avoiding the problem of integrated heat damage.

[0012] Therefore, the range extender of the utility model only needs the power generated by the turbine unit to drive the compressor unit and the magnetic component to rotate relative to the stator assembly, thereby generating electric current, which greatly improves the power generation efficiency of the range extender; and the compressor flow channel isolates the stator assembly from the combustion chamber, and the high temperature generated by the combustion chamber will not affect the normal operation of the stator assembly, solving the problem of integrated heat damage.

[0013] According to the range extender provided in the embodiment of the utility model, an intake passage connected to the air inlet of the combustion chamber is formed inside the shell, the other end of the compressed air passage extends into the shell and is connected to the combustion chamber of the turbine unit through the intake passage, and the intake passage extends around the combustion chamber.

The air intake channel is arranged around the combustion chamber, so that the gas can be heated when passing through the outside of the combustion chamber, thereby improving the combustion efficiency.

[0015] According to the range extender provided in the embodiment of the utility model, the magnetic component includes a plurality of permanent magnets arranged at the ends of the compressor blades.

[0016] By adopting the above technical solution, the magnetic component is arranged at the end of the compressor blade, so that the rotation of the compressor blade drives the rotation of the magnetic component, thereby realizing the linkage between the two. The magnetic component is arranged as a plurality of permanent magnets, which not only optimizes the magnetic field and improves the power generation efficiency; in addition, the arrangement of a plurality of permanent magnets can also realize magnetic exchange, thereby changing the direction and size of the magnetic flux, and finally adjusting the rotation speed of the rotor assembly.

[0018] By adopting the above technical solution, multiple permanent magnets and compressor blades are set as a whole. The overall setting method allows the permanent magnets and compressor blades to maintain a synchronous state, move synchronously, or stop, thereby improving the operating efficiency. As a component of the compressor blade, the silicon steel sheet has the advantages of low loss and high efficiency. The permanent magnet is connected to the end of the silicon steel sheet by inlaying.

[0019] According to the range extender provided in the embodiment of the utility model, the stator assembly includes a plurality of generator stators, each generator stator includes a stator core and a stator winding wound around the outer periphery of the stator core; wherein each generator stator is fixedly arranged on the inner wall of the shell.

[0020] With the above technical solution, the stator windings of multiple generator stators are arranged along the circumference of the rotor assembly. When the permanent magnet of the generator rotor rotates, a rotating magnetic field is generated in the stator, thereby generating current in the generator stator winding coil. Each generator stator is fixedly arranged on the inner wall of the shell, ensuring a stable relationship between the generator stator and the shell, so that the generator stator can work better.

[0021] According to the range extender provided in the embodiment of the utility model, the power generation unit and the combustion chamber are located at opposite ends of the shell.

[0022] By adopting the above technical solution, the power generation unit and the combustion chamber are arranged at opposite ends of the shell. The arrangement of the opposite ends keeps a distance between the power generation unit and the combustion chamber. On the one hand, it prevents the high temperature generated by the combustion chamber from burning the power generation unit; on the other hand, the power generated by the work of the combustion chamber will be transmitted to the rotor assembly of the power generation unit through the rotation of the shaft, providing sufficient working space for force transmission.

[0023] According to the range extender provided in the embodiment of the utility model, a conical partition is arranged between the air compression unit and the combustion chamber, and a plurality of fuel injection ports are arranged on both sides of the combustion chamber away from the conical partition.

[0024] With the above technical solution, the conical partition is set to separate the air compressor unit from the combustion chamber. On the one hand, it prevents the high temperature generated by the combustion process in the combustion chamber from affecting the air compressor unit; on the other hand, the conical partition blocks the backflow of gas and other media generated during the combustion in the combustion chamber, ensuring the safe and stable operation of the range extender. The oil sprayed from the fuel injection port is one of the combustion media of the combustion chamber and is set on both sides of the combustion chamber away from the conical partition, so that the air passing through the air intake channel and the oil sprayed from the fuel injection port near one side can be mixed and ignited to achieve combustion and work.

[0025] According to the range extender provided in the embodiment of the utility model, an exhaust port is provided at one end of the turbine unit away from the power generation unit.

[0030] By adopting the above technical solution, the control unit controls the throttle opening through the throttle opening controller, thereby controlling the combustion energy and the speed of the turbine unit to meet the energy supply needs of the car in different scenarios and improve the controllability of driving operations.

[0031] The beneficial effects of the utility model are:

[0058] With the continuous development of automobile power systems, car drivers pay more and more attention to the configuration and operating performance of automobile power systems. The power system of an automobile is mainly composed of an engine system and a transmission system, in which the engine assembly is composed of two major mechanisms and five major systems. The power generated by the engine is transmitted through a series of power transmissions through the two major mechanisms and five major systems and finally transmitted to the wheels. This traditional automobile power system usually only relies on fuel engines to provide power for the vehicle, which is not only costly to use, but also increasingly unable to meet the environmental protection requirements of the market.

[0059] In this regard, with the continuous advancement of automobile technology, various new energy vehicles have gradually emerged. Extended-range new energy vehicles are deeply loved by users for their excellent environmental protection and long cruising range.

[0060] Range-Extended Electric Vehicle (REEV) is a type of vehicle that combines the characteristics of a battery electric vehicle (BEV) and a traditional fuel vehicle. The following is a detailed introduction to its characteristics and working principle.

[0061] (1) Features

[0062] Hybrid system: Extended-range new energy vehicles are usually equipped with an electric drive system and a small internal combustion engine generator combination. The battery pack supplies power to the electric drive system to drive the vehicle.

[0063] Extended driving range: When the battery power is low, the internal combustion engine generator automatically starts to provide power to the electric drive system by generating electricity, while also charging the battery pack, thereby extending the driving range.

[0064] Flexible usage: Extended-range new energy vehicles can be driven by batteries themselves or by using internal combustion engines to generate electricity to increase the vehicle's range, solving the limitations of pure electric vehicles when traveling long distances or when charging is not possible.

[0065] (2) Working principle

[0066] During driving, the battery converts electrical energy into mechanical energy through an inverter to drive the motor, thereby driving the car forward.

[0067] When the battery is low, the car's range extender kicks in and charges the battery or directly powers the drive motor, extending the range.

[0068] (3) Advantages

[0069] Longer cruising range: Compared with pure electric vehicles, extended-range new energy vehicles have a longer cruising range and are more suitable for long-distance driving.

[0070] High fuel economy: The internal combustion engine operates at optimal efficiency when working, converting fuel into electrical energy for use by the electric motor, which has better fuel economy.

[0071] Strong driving performance: Extended-range new energy vehicles can utilize the power output of the internal combustion engine and the electric motor at the same time when driving, providing stronger acceleration performance and power response.

[0072] Charging flexibility: Extended-range new energy vehicles can be charged through charging piles or by using the internal combustion engine to charge the battery while driving.

[0073] Common extended-range new energy vehicles are all equipped with a range extender to assist the power system. A range extender with excellent performance can improve power generation efficiency and effectively increase cruising range. In some solutions in the prior art, the range extender mainly generates electricity by driving a generator with a piston engine. Due to the limitations of its own structure, the speed and power of this range extender are greatly limited. Especially when the car is running at high speed, it is difficult for the range extender to achieve a higher power output. In the long run, the high-load working environment is likely to cause its own performance to deteriorate, and the power generation efficiency is limited. In addition, the high temperature generated in the combustion chamber during the power generation process directly contacts the stator structure of the power generation unit. The high temperature greatly increases the probability of failure of the coil in the stator structure, which may in turn damage the range extender structure.

[0074] In response to the above problems, the present application provides a range extender that can be used in automobiles. The housing of the range extender is provided with a compressor unit, a turbine unit, and a power generation unit, wherein the combustion chamber of the turbine unit can burn and do work, and the energy generated by the combustion will drive the compressor blades of the compressor impeller and the magnetic components of the power generation unit to rotate synchronously through the shaft, thereby improving the power generation efficiency. A compressor flow channel is formed between the compressor blades to isolate the stator assembly from the combustion chamber, ensuring that the stator assembly will not be burned due to the high temperature heat damage of the combustion chamber.

[0075] In order to more clearly understand the range extender provided in the present application, the structure of the range extender is described in detail below with reference to the accompanying drawings.

[0076] See also Figure 1This range extender includes a housing 1, and a compressor unit 10, a turbine unit 20 and a power generation unit 30 coaxially arranged inside the housing 1, wherein the power generation unit 30 further includes a stator assembly 31 and a rotor assembly 32, and the rotor assembly 32 includes a magnetic component 320, which is arranged around the compressor unit 10 and can rotate synchronously with the compressor impeller 11 of the compressor unit 10; a compressed air flow channel 12 is arranged between the compressor impeller 11 of the compressor unit 10, one end of the compressed air flow channel 12 is connected to the outside of the housing 1, and the other end extends into the housing 1 and is connected to the combustion chamber 21 of the turbine unit 20, and the compressed air flow channel 12 isolates the stator assembly 31 from the combustion chamber 21. In this embodiment, the stator assembly 31 of the power generation unit 30 is arranged around the magnetic component 320 of the rotor assembly 32, and there are intervals between the stator assemblies 31.

[0077] In the present utility model, the range extender isolates the stator assembly 31 from the combustion chamber 21 through the compressed air passage 12 between the compressed air blades 110. One end of the compressed air passage 12 is connected to the outside of the housing 1, and the external air medium can be sucked in through this end; and the other end of the compressed air passage 12 extends to the inside of the housing 1 and is connected to the combustion chamber 21 of the turbine unit 20. The entire compressed air passage 12 separates the stator assembly 31 on one side of the housing 1 and the combustion chamber 21 on the other side. Since the combustion medium in the combustion chamber 21 burns and generates a large amount of heat when air is introduced, the heat gathers in a limited space to form a high-temperature environment, which will cause failure or other high-temperature damage to the coils and other structures in the stator assembly 31 that are in contact with or attached to it. However, the setting of the compressed air passage 12 effectively isolates the high-temperature damage of the combustion chamber 21 to the stator assembly 31, allowing the range extender to work safely and smoothly.

[0078] The compressor unit 10 and the turbine unit 20 are coaxially arranged. The power generated by the high temperature of the combustion chamber 21 of the turbine unit 20 drives the compressor impeller 11 of the compressor unit 10 to rotate through the shaft. Since the magnetic component 320 of the rotor assembly 32 and the compressor impeller 11 are also synchronously rotated, the power generated by the turbine unit 20 will drive the compressor impeller 11 and the magnetic component 320 to rotate coaxially. The rotation of the magnetic component 320 will generate a magnetic field, and this magnetic field will cut the magnetic flux lines relative to the stator assembly 31 while the magnetic component 320 rotates. This movement generates an induced potential on the stator. When the coil on the stator assembly 31 forms a closed loop, current is generated, which effectively improves the power generation efficiency.

[0079] The structure of the range extender is explained in detail below.

[0080] The shape of the range extender is not limited, and it can be a regular structure such as a cylinder, or an irregular structure.

[0081] It should be noted that the exterior of the range extender is wrapped by a shell 1, and the structure of the shell 1 is regarded as the structure of the range extender. The specific structure of the shell 1 only needs to meet the actual assembly requirements of the automobile, and this embodiment does not make any specific limitations on this.

[0082] Based on the above range extender structure, please refer to Figure 1 The housing 1 of the range extender includes a compressor unit 10 and a turbine unit 20 coaxially arranged in the housing 1 , wherein the compressor unit 10 includes a compressor impeller 11 , and the turbine unit 20 includes a combustion chamber 21 .

[0083] The compressor impeller 11 is configured to have a structure in which compressor blades 110 are evenly arranged along the circumference of the rotating shaft. It should be noted that, with regard to the number and structure of the compressor blades 110, as long as there is a gap between adjacent compressor blades 110 and there is sufficient airflow passing through the gap, the specific number and structure of the blades are not specifically limited in this embodiment.

[0084] The specific structure of the combustion chamber 21 of the turbine unit 20 only needs to satisfy the combustion of the gas medium and the fuel medium, and this embodiment does not make any specific limitation to this.

[0085] For further information, please see Figure 1 A compression flow channel 12 is formed between the compression blades 110, one end of the compression flow channel 12 is connected to the outside of the shell 1, and the other end extends into the shell 1 and is connected to the combustion chamber 21 of the turbine unit 20. The number of the compression flow channels 12 is set to 2 in this embodiment, and can also be set to other compression flow channels 12.

[0086] In one embodiment, the number of the compressed air passages 12 is set to 2, and the outside air enters the intake passage through the compressed air passages 12 between the compressor blades 110, and finally enters the combustion chamber 21. The fuel sprayed from the fuel injection port 210 in the combustion chamber 21 and the air flowing into the intake passage 22 form a mixed medium for combustion, and the combustion work generates a large amount of heat. The heat gathers in the limited space of the combustion chamber 21, driving the turbine unit 20 to rotate around the axis. Since the turbine unit 20 is coaxially arranged with the compressor unit 10, the rotation of the turbine unit 20 drives the compressor unit 10 and the compressor impeller 11 of the compressor unit 10 to rotate, realizing the conversion of internal energy into mechanical rotation and transmission. The number of the compressed air passages 12 is set to 2, which ensures that there are enough channels for the outside air to enter the combustion chamber 21 for combustion reaction.

[0087] In another embodiment, the number of the compressed air flow channels 12 is set to be multiple (for example, 3, 4, etc.). On the one hand, the setting of the multiple compressed air flow channels 12 provides sufficient air medium guarantee for the combustion chamber 21; on the other hand, the multiple compressed air flow channels 12 are adapted to the structure of the combustion chamber 21. Taking 3 compressed air flow channels 12 as an example, they are wrapped around the outside of the combustion chamber 21, and the gas medium is heated, thereby improving the combustion efficiency.

[0088] It should be noted that the number of compressed air channels 12 must meet the design requirements of the range extender structure itself, not hinder the normal operation of the compressor unit 10 and the turbine unit 20, and be able to isolate the combustion chamber 21 from the high combustion temperature.

[0089] For further information, please see Figure 1 The compressed air passage 12 separates the stator assembly 31 from the combustion chamber 21. The housing 1 is also provided with an intake passage 22 connected to the intake port of the combustion chamber 21, and the intake passage 22 extends around the combustion chamber 21. The compressed air passage 12 is used as a passage to separate the stator assembly 31 from the combustion chamber 21. When the air is taken in, the gas first enters the housing 1 through the compressed air passage 12 between the compressed air blades 110, and is connected to the intake passage 22. The airflow in the compressed air passage 12 can separate the stator assembly 31 from the combustion chamber 21, and prevent the high temperature generated by the combustion in the combustion chamber 21 from being directly transferred to the stator assembly 31 and causing damage. The exhaust gas generated by the combustion is finally discharged through the exhaust port 23 on the turbine unit 20.

[0090] Furthermore, the intake passage 22 extends around the combustion chamber 21 , and the intake passage 22 may be fully covered on the outside of the combustion chamber 21 , or may be partially covered on the outside of the combustion chamber 21 .

[0091] In one embodiment, see Figure 1 The intake passage 22 is fully covered on the outside of the combustion chamber 21, so that the intake passage 22 and the combustion chamber 21 are in full contact. When the gas flows through the outside of the combustion chamber 21, it can be fully heated, thereby improving the combustion efficiency.

[0092] In another embodiment, according to actual assembly requirements, the intake passage 22 is configured to wrap the outer side of the combustion chamber 21 in a non-fully covering manner. On the basis of ensuring the most complete contact between the intake passage 22 and the combustion chamber 21, the intake passage 22 and the outer side of the combustion chamber 21 are not fully covered.

[0093] For further information, see Figure 1 as well as Figure 2, a power generation unit 30 is also arranged in the housing 1, and the power generation unit 30 includes a stator assembly 31 and a rotor assembly 32, wherein the rotor assembly 32 includes a magnetic component 320, and the stator assembly 31 includes a plurality of generator stators 310. In this embodiment, the magnetic component 320 is set as a permanent magnet 321, and the permanent magnet 321 is fixedly connected to the end of the corresponding compressor blade 110 through a silicon steel sheet 330 to form a whole; and the turbine unit 20 drives the compressor blade 110 to rotate through the shaft, thereby driving the permanent magnet 321 to rotate, and the plurality of permanent magnets 321 and the plurality of generator stators 310 of the stator assembly 31 rotate relative to each other, thereby generating an alternating current.

[0094] For further information, please see Figure 1 as well as Figure 2 The power generation unit 30 and the combustion chamber 21 are located at opposite ends of the shell 1, that is, there is a gap between the power generation unit 30 and the combustion chamber 21. On the one hand, the gap provides the compressor unit 10 and the turbine unit 20 between the power generation unit 30 and the combustion chamber 21 with sufficient force transmission space; on the other hand, the compressor flow channel 12 and the intake channel 22 provided for the power generation unit 30 and the combustion chamber 21 provide sufficient intake space, so that the intake space is fully isolated from the high temperature damage of the combustion chamber 21.

[0095] For further information, see Figure 1 A plurality of fuel injection ports 210 are provided on both sides of the combustion chamber 21 away from the conical partition 40. The fuel injection ports 210 can spray out combustible medium, and this combustible medium can be mixed and burned with the air from the intake passage 22, generating a large amount of heat to drive the turbine unit 20 to rotate around the axis.

[0096] It should be noted that any type of combustible medium can be used as long as it can be mixed with the air medium and burned to drive the turbine unit 20 to rotate around the axis and meet the combustion environment inside the combustion chamber 21.

[0097] It should be noted that the magnetic component 320 can be a permanent magnet 321 or other magnetic materials, as long as it can cut the magnetic flux lines between the multiple generator stators 310 of the stator assembly 31 while rotating to generate current. This embodiment does not specifically limit the type of the specific magnetic component 320.

[0098] For further information, see Figure 1 Each generator stator 310 also includes a stator core 311 and a stator winding 312 wound around the outer circumference of the stator core 311. Each generator stator 310 is fixedly arranged on the inner wall of the shell 1, so that the position of each generator stator 310 is fixed relative to the shell 1, which facilitates the magnetic component 320 of the rotor assembly 32 to better rotate around the generator stator 310.

[0099] For further information, see Figure 1 A conical partition 40 is provided between the air compressor unit 10 and the combustion chamber 21 , and the conical partition 40 serves to isolate the air compressor unit 10 from the combustion chamber 21 , thereby preventing the high temperature generated in the combustion chamber 21 from burning the air compressor unit 10 .

[0100] The utility model also provides a car, which comprises a range extender arranged on the car.

[0101] The specific installation location of the range extender on the car can be determined as long as it meets the requirements of reasonable installation of the car structure while improving power generation efficiency and solving the problem of high-temperature heat damage.

[0102] For further information, see Figure 1 , Figure 3 as well as Figure 4 The range extender also includes a control unit 50, which is connected to a throttle opening controller of the vehicle to control the amount of fuel supplied.

[0103] Specifically, when the throttle opening increases, the control unit 50 will control the combustion chamber 21 in the range extender to allow sufficient air and combustion medium to fully burn, so that the range extender can fully supply power to the vehicle battery; when the throttle opening decreases, the control unit 50 will control the combustion chamber 21 of the range extender to reduce combustion and generate high temperature, so that the range extender can reduce the amount of power supplied to the vehicle battery.

[0104] Of course, this range extender can also be used in aviation, shipping, robotics and other fields, and the present utility model does not make specific limitations on this.

[0105] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
