Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle design technology, and in particular to an architecture system for range-extended vehicles. Background Technology

[0002] In the field of traditional gasoline-powered vehicle technology, since gasoline-powered vehicles generate power by burning gasoline, diesel, or other fuels to move the vehicle, they do not require a large area (occupying a large area in the middle of the frame) of energy storage batteries at the bottom of the frame, as is the case with new energy vehicles. Therefore, in traditional gasoline-powered vehicles, designers can set the exhaust gas treatment system and the engine in two separate areas, the front and the rear of the vehicle. The exhaust pipe can then extend from the front to the rear of the vehicle to connect the engine and the exhaust gas treatment system, ensuring normal exhaust emissions. This avoids the design flaw of a bulky structure at the front or rear of the vehicle caused by concentrating the exhaust gas treatment system and the engine at the front or rear.

[0003] However, in the field of range-extended electric vehicle (REEV) technology, since a large area of ​​energy storage battery needs to be installed in the middle of the vehicle, and the vehicle itself also has a range extender and exhaust aftertreatment system, if designers refer to the exhaust layout of traditional gasoline vehicles and place the exhaust aftertreatment system and range extender at the rear and front of the vehicle respectively, and still have the exhaust pipe extend from the front to the rear, then the placement of the exhaust pipe will inevitably occupy part of the space in the middle area of ​​the vehicle frame, which will prevent the size of the energy storage battery from being further increased, and consequently prevent the range of the REEV from being further improved.

[0004] Meanwhile, when the exhaust pipe is extended from the front of the vehicle to the rear, it will inevitably be close to or even in contact with the energy storage battery. This means that when the high-temperature exhaust gas emitted during the operation of the range extender flows to the exhaust gas treatment system through the exhaust pipe, it will also dissipate some of the heat to the energy storage battery, resulting in an additional thermal management burden on the energy storage battery and reducing the safety of its use. Utility Model Content

[0005] As an improvement on the prior art, this utility model provides an architecture system for range-extended electric vehicles, in which the range extender and exhaust gas treatment system are both installed at the rear of the vehicle, while the energy storage battery system is still located in the middle of the vehicle frame. This allows the exhaust pipe to connect the range extender and exhaust gas treatment system without having to pass through the energy storage battery system. Consequently, the size of the energy storage battery system can be further increased to improve the vehicle's range and enhance battery safety.

[0006] The technical solution of this utility model to solve the above problems is: to provide an architecture system for range-extended electric vehicles, the architecture system including a frame, an energy storage battery system, a range extender, an exhaust gas treatment system, and an exhaust connecting pipe, the energy storage battery system being located in the middle of the frame, the range extender and the exhaust gas treatment system being located at the rear end of the frame, and the exhaust connecting pipe being used to connect the range extender and the exhaust gas treatment system.

[0007] As a preferred embodiment of this invention, it also includes a motor, which is disposed at the front end of the vehicle frame.

[0008] As a preferred embodiment of this utility model, the motor is a dual-shaft output motor, and both output shafts of the motor are coaxially arranged with the wheel drive shaft at the front end of the range-extended vehicle.

[0009] As a preferred embodiment of the present invention, the exhaust gas treatment system includes a catalytic converter assembly and a muffler assembly. One end of the exhaust gas connecting pipe is connected to the catalytic converter, and the catalytic converter is connected to the muffler assembly. The outlet end of the muffler assembly is provided with an exhaust gas tailpipe.

[0010] As a preferred embodiment of this utility model, it further includes an air intake pipe connected to the air intake port of the range extender, the air intake pipe being disposed at the rear end of the vehicle frame, and the air intake end of the air intake pipe being disposed towards the side of the vehicle frame and biased towards the front of the vehicle frame.

[0011] As a preferred embodiment of this invention, the air intake pipe is further provided with an air filter.

[0012] As a preferred embodiment of this utility model, it also includes an oil tank, which is installed at the rear end of the vehicle frame.

[0013] As a preferred embodiment of this invention, the range extender is located between the oil tank and the exhaust gas treatment system.

[0014] As a preferred embodiment of this invention, the oil tank is located between the energy storage battery system and the range extender.

[0015] The beneficial effects of this utility model are: 1. The exhaust connection pipe is not close to or in contact with the energy storage battery system. When the high-temperature exhaust gas generated when the fuel is burned in the range extender is discharged to the exhaust gas treatment system through the exhaust connection pipe, the high-temperature exhaust gas will not affect the safety of battery use.

[0016] 2. The exhaust connection pipe is only located in the rear area of ​​the vehicle. The exhaust connection pipe will not encroach on the installation space of the energy storage battery system, which can further increase the energy storage capacity of the energy storage battery system and further increase the vehicle's range.

[0017] 3. The motor and range extender are located on both sides of the front and rear of the vehicle. Since it is a range extender, its size is much smaller than that of a traditional fuel vehicle engine. Therefore, even if the range extender is installed at the rear of the vehicle at the same time as the exhaust gas treatment system, it will not cause the rear structure of the vehicle to be crowded.

[0018] 4. The fuel tank is located on the innermost side, which further reduces the risk of the fuel tank rupture in the event of a collision, thus improving driving safety. Attached Figure Description

[0024] It should be noted that the technical solution of the architecture system for range-extended electric vehicles in this embodiment relates to the distribution and layout of the main components of the power system and the battery system on the vehicle frame. As for other technical details that are unrelated to or less related to the layout of the power system and battery system on the vehicle frame, such as how the power system and the vehicle wheels are connected, how the battery system and the power system components are connected, and the specific composition of the energy storage battery system, the applicant will not elaborate on them in the following text. Those skilled in the art can directly refer to the prior art.

[0025] Specifically, please refer to Figure 1 , refer to Figure 1 As shown in the diagram, a specific embodiment of this utility model provides a structural system for a range-extended electric vehicle, including a frame 11, a motor 16, an energy storage battery system 12, a range extender 13, an exhaust gas treatment system 14, and an exhaust connecting pipe 15. The left side of the frame 11 is the front end, and the right side is the rear end. A central arrangement area for the energy storage battery system 12 is provided in the middle of the frame 11, and the width of this central arrangement area is approximately equal to the width of the central region of the frame 11. The motor 16 is positioned along... Figure 1The system is arranged vertically, essentially horizontally at the front end of the vehicle frame 11. The energy storage battery system 12 is located in the central area and is conventionally connected to the motor 16. The energy storage battery system 12 supplies power to the motor 16, causing the motor 16 to rotate the front wheels and propel the vehicle. The range extender 13 is located at the rear end of the vehicle frame 11 and is also conventionally connected to the energy storage battery system 12 to charge its batteries. The exhaust gas treatment system 14 is also located on the vehicle frame. At the rear end of vehicle 11, the exhaust gas treatment system 14 and the range extender 13 are connected to each other through a short exhaust connecting pipe 15. The exhaust connecting pipe 15 does not need to extend from the front to the rear of the vehicle to occupy the installation space in the central arrangement area during installation. Moreover, the exhaust gas generated by the range extender 13 during operation can also flow directly to the exhaust gas treatment system 14 through the short exhaust connecting pipe 15 instead of flowing through the energy storage battery system 12 installed in the central arrangement area. After being treated by the exhaust gas treatment system 14, it is discharged to the outside of the vehicle through the exhaust tailpipe 17.

[0026] Furthermore, in some embodiments of this utility model, the motor 16 is a dual-output shaft motor, and the output shafts at both ends of the motor 16 are each connected to the wheel axle of a front wheel of a car to drive the two front wheels of the car to rotate synchronously, so as to realize the front-wheel drive design scheme of the car.

[0027] Furthermore, although Figure 1 Although not shown, it is understood that in some embodiments of the present invention, the exhaust gas treatment system 14 includes a catalytic converter assembly and a muffler assembly. One end of the exhaust gas connecting pipe 15 is connected to the range extender 13 and the other end is connected to the catalytic converter assembly. The muffler assembly is connected to the exhaust port of the catalytic converter assembly, and the exhaust port of the muffler assembly is provided with an exhaust tailpipe 17.

[0028] In response, when the range extender 13 is operating to charge the energy storage battery system 12, the combustion exhaust gas generated by the range extender 13 burning gasoline can flow into the catalytic converter assembly through the exhaust connection pipe 15. The catalytic converter purifies the combustion exhaust gas, and the purified combustion exhaust gas then passes through the muffler assembly to reduce exhaust noise, and finally is discharged from the exhaust tailpipe 17.

[0029] Further, please refer to Figure 1 , refer to Figure 1 As shown in the diagram, in some embodiments of this utility model, an air intake pipe is also provided on the upper right side of the frame 11. One end of the air intake pipe is connected to the air intake of the range extender 13, and the other end is positioned towards the side of the frame 11 and biased towards the front of the frame 11, that is, towards... Figure 1 The setting extends to the upper left.

[0030] In this regard, when driving the range-extended vehicle of this embodiment, outside air can flow into the range extender 13 through the air intake pipe to provide the necessary oxygen for gasoline combustion, ensuring the gasoline combustion ratio and the power generation efficiency of the range extender 13.

[0031] In addition, an air filter 19 is also installed on the frame 11. The air filter 19 is connected to the intake pipe 18. The air filter 19 is used to filter dust and other impurities in the air to prevent dust and other impurity particles from flowing into the range extender 13 along the intake pipe 18 and to prevent damage to the range extender 13.

[0032] Further, please refer to Figure 1 , refer to Figure 1 As shown in the orientation, in some embodiments of this utility model, the fuel tank 20 on the frame 11 is located at the rear end of the frame 11, and the fuel tank 20 is located between the energy storage battery system 12 and the range extender 13.

[0033] In this way, in the event of a rear-end collision, the exhaust gas treatment system 14 and the range extender 13 located on the right side of the fuel tank 20 can both serve as buffer structures to block the rear of the fuel tank 20, thereby reducing the probability of an explosion when the car is involved in an accident.

[0034] Anything not mentioned above applies to existing technologies.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
