[0050] The embodiment of the present application provides a chassis assembly of a vehicle, Figure 1 A schematic structural diagram of the chassis assembly of a vehicle provided in an embodiment of the present application.

[0051] Specifically, see Figure 1 The chassis assembly of the vehicle includes: a frame 100; a power battery assembly 200, which is arranged on the frame 100; an extended-range fuel assembly 300, which is arranged on the frame 100 and is located on one side of the power battery assembly 200; a range extender 101, a high-voltage assembly 400 and a low-voltage assembly 500, which are sequentially arranged on the frame 100; an electromagnetic isolation assembly 600, which is arranged on the frame 100 and is located between the high-voltage assembly 400 and the low-voltage assembly 500. The electromagnetic isolation assembly 600 is used to isolate electromagnetic waves between the high-voltage assembly 400 and the low-voltage assembly 500.

[0052] The chassis assembly of the vehicle provided in the embodiment of the present application is provided with a frame 100. The frame 100 serves as a supporting skeleton of the vehicle and can provide a mounting base for various components of the vehicle.

[0053] By setting the power battery assembly 200 on the vehicle frame 100, the installation of the power battery assembly 200 is achieved, so that the vehicle can use the electric energy of the power battery assembly 200 as the power for vehicle operation, thereby making the vehicle energy-saving and environmentally friendly and having low operating costs.

[0054] By placing the range-extending fuel assembly 300 on the vehicle frame 100 and locating it on one side of the power battery assembly 200, a compact layout of the core components of the vehicle's chassis assembly is achieved. Furthermore, the range-extending fuel assembly 300 provides an additional energy source for the vehicle, extending its range and improving its cruising range, thus resolving the issue of shorter range in pure electric vehicles.

[0055] By sequentially arranging the range extender 101, the high-voltage assembly 400, and the low-voltage assembly 500 on the vehicle frame 100, the range extender 101 can generate electricity using the fuel in the range-extending fuel assembly 300, thereby providing an additional energy source for the vehicle. The high-voltage assembly 400 can be used for transmitting and converting high-voltage electricity of the vehicle's electrical devices, and the low-voltage devices can be used for transmitting and converting low-voltage electricity of the vehicle's electrical devices.

[0056] By setting the electromagnetic isolation component 600 on the frame 100 and the electromagnetic isolation component 600 being located between the high-voltage component 400 and the low-voltage component 500, the electromagnetic isolation component 600 can effectively isolate the electromagnetic waves between the high-voltage component 400 and the low-voltage component 500 to prevent the two from interfering with each other, thereby improving the stability of the operation of the vehicle's electrical devices.

[0057] It is understandable that Figure 1 Some components of the vehicle chassis assembly are only schematically shown, and the actual shape, actual size, actual position and actual structure of these components are not subject to Figure 1 The vehicle's chassis assembly may also include Figure 1 More or fewer parts.

[0058] The following describes the preferred technical solution of the chassis assembly of the vehicle according to the embodiment of the present application in conjunction with the accompanying drawings, wherein: Figure 2 A top view of the vehicle's chassis assembly. Figure 3 FIG. 1 is a structural diagram of the connection between the first axle 700 and the frame 100. Figure 4 Schematic diagram of the structure of the electromagnetic isolation component.

[0059] In the embodiment of the present application, the high-voltage assembly 400 includes a high-voltage auxiliary drive controller and a high-voltage distribution box.

[0060] The high-voltage auxiliary drive controller is an auxiliary drive device used to control and manage the vehicle's high-voltage electrical components, such as the air conditioning compressor and electric power steering pump. It coordinates the operation of these components, ensuring they receive the appropriate power supply when needed and optimizing the vehicle's energy efficiency. The high-voltage auxiliary drive controller emits powerful electromagnetic waves.

[0061] The high-voltage distribution box, as the center of high-voltage power distribution, is used to distribute high-voltage power from the power battery assembly 200 to the high-voltage auxiliary drive controller. The high-voltage distribution box can emit strong electromagnetic waves.

[0062] In addition, the low-voltage component 500 includes a chassis domain controller and a low-voltage battery distribution box.

[0063] The chassis domain controller (CDC) serves as the central control unit for the vehicle's chassis system, coordinating and managing various chassis-related subsystems, such as suspension, braking, and steering. The CDC receives information from sensors in each subsystem and issues control commands based on the vehicle's overall control strategy to optimize handling, stability, and comfort. The CDC can emit weak electromagnetic waves.

[0064] The low-voltage battery distribution box is used to manage and distribute electrical energy to low-voltage electrical components. It houses a low-voltage battery and distributes the energy to various low-voltage components in the vehicle, such as the lighting system, infotainment system, and various controllers. The low-voltage battery distribution box can emit relatively weak electromagnetic waves.

[0065] In summary, the strong electromagnetic waves emitted by the high-voltage power devices of the high-voltage component 400 and the weak electromagnetic waves emitted by the low-voltage power devices of the low-voltage component 500 are likely to interfere with each other. Therefore, by setting up an electromagnetic isolation component 600, the electromagnetic isolation component 600 is set between the high-voltage component 400 and the low-voltage component 500, which can effectively isolate the electromagnetic waves between the high-voltage component 400 and the low-voltage component 500 to prevent the two from interfering with each other, thereby improving the stability of the operation of the vehicle's high-voltage power devices and low-voltage power devices.

[0066] In some embodiments, see Figure 1 and Figure 2 , the electromagnetic isolation component 600 is a metal part.

[0067] When electromagnetic waves encounter metal components, they reflect them. This reflection mechanism effectively blocks the propagation of electromagnetic waves and significantly reduces electromagnetic interference between the high-voltage component 400 and the low-voltage component 500.

[0068] It should be noted that this embodiment does not limit the specific connection method between the electromagnetic isolation assembly 600 and the vehicle frame 100, and can be adjusted according to specific needs. For example, the electromagnetic isolation assembly 600 can be connected to the vehicle frame 100 by welding, riveting, or screwing.

[0069] In other embodiments, see Figure 4 The electromagnetic isolation component 600 includes: a support member 610, which is arranged on the frame 100 and is located between the high-voltage component 400 and the low-voltage component 500; an isolation layer 620, which is arranged on the support member 610 and is used to isolate electromagnetic waves between the high-voltage component 400 and the low-voltage component 500.

[0070] Since the vehicle frame 100 itself has good rigidity and stability, arranging the support member 610 on the vehicle frame 100 can ensure that the electromagnetic isolation assembly 600 remains stable during the vehicle driving process.

[0071] In a specific implementation, the support member 610 is located between the high-voltage assembly 400 and the low-voltage assembly 500, and the isolation layer 620 is disposed on the support member 610 so that the isolation layer 620 is located between the high-voltage assembly 400 and the low-voltage assembly 500. Furthermore, because the isolation layer 620 itself has an electromagnetic isolation effect, the isolation layer 620 located between the high-voltage assembly 400 and the low-voltage assembly 500 can isolate the electromagnetic waves emitted by the high-voltage assembly 400 and the low-voltage assembly 500, preventing mutual interference between the two.

[0072] It should be noted that this embodiment does not limit the specific structure and type of the support member 610, as long as it can achieve the supporting and isolating functions. Exemplarily, the support member 610 is a steel frame or a plastic member.

[0073] It should also be noted that this embodiment does not limit the specific connection method between the support member 610 and the frame 100, and can be adjusted according to specific needs. For example, the support member 610 can be connected to the frame 100 by welding, riveting, or screwing.

[0074] In some specific embodiments (not shown in the figures), the isolation layer 620 is disposed on a side of the support member 610 close to the high-voltage assembly 400 .

[0075] Because the high-voltage assembly 400 can emit strong electromagnetic waves and the low-voltage assembly 500 can emit weak electromagnetic waves, the high-voltage assembly 400 can significantly interfere with the low-voltage assembly 500. In this embodiment, by providing an isolation layer 620 on the side of the support member 610 close to the high-voltage assembly 400, the isolation layer 620 can effectively isolate the strong electromagnetic waves emitted by the high-voltage assembly 400, thereby preventing the high-voltage assembly 400 from interfering with the operation of the low-voltage assembly 500.

[0076] In other specific embodiments, see Figure 4 The isolation layer 620 is disposed around the peripheral side of the support member 610 .

[0077] By wrapping the isolation layer 620 around the circumference of the support member 610, a complete electromagnetic shielding layer is formed on the circumferential surface of the support member 610. As a result, electromagnetic waves emitted by the high-voltage assembly 400 and the low-voltage assembly 500 cannot penetrate from any side or corner of the support member 610. This all-around winding structure effectively blocks the propagation of electromagnetic waves and significantly improves the electromagnetic isolation effect of the electromagnetic isolation assembly 600.

[0078] In some further specific embodiments, the isolation layer 620 is a metal layer.

[0079] When electromagnetic waves encounter the metal layer, the metal layer can reflect the electromagnetic waves. This reflection mechanism can effectively prevent the propagation of electromagnetic waves and significantly reduce the electromagnetic interference between the high-voltage component 400 and the low-voltage component 500.

[0080] Furthermore, the isolation layer 620 is a copper layer or an aluminum layer. The copper layer has good machinability, and the aluminum layer is light in weight and low in cost.

[0081] In practice, prefabricated copper or aluminum foil can be directly attached to the surface of the support member 610, which is relatively simple. A uniform layer of copper or aluminum can be deposited on the surface of the support member 610 through an electrochemical process. Copper or aluminum powder can also be sprayed onto the surface of the support member 610.

[0082] In some other specific embodiments, the isolation layer 620 is a magnetic layer.

[0083] By selecting a magnetic layer as the isolation layer 620 , the high magnetic permeability of the magnetic layer can provide a low-impedance channel for electromagnetic waves, guiding electromagnetic energy to propagate within and along the isolation layer 620 and eventually attenuate, thereby achieving an electromagnetic isolation effect.

[0084] Furthermore, the isolation layer 620 is a soft ferrite layer, which has high magnetic permeability and low hysteresis loss.

[0085] In practice, magnetic powder can be mixed with a suitable adhesive and directly coated on the surface of support member 610. This method is applicable to support members 610 of various shapes and allows for control of coating thickness. Prefabricated magnetic films (such as soft ferrite films) can also be attached to the surface of support member 610.

[0086] In some specific implementations, see Figure 4The electromagnetic isolation component 600 has a wire hole 630 , which passes through both sides of the electromagnetic isolation component 600 . The wire harness is passed through the wire hole 630 to connect the high-voltage component 400 and the low-voltage component 500 .

[0087] In this embodiment, by setting a wire hole 630 on the electromagnetic isolation component 600, a shorter wiring harness can be used to connect the high-voltage component 400 and the low-voltage component 500, which not only saves costs but also shortens the transmission distance of the control signal and improves the control accuracy and response speed.

[0088] In some other embodiments, see Figure 1 and Figure 2 The vehicle frame 100 includes a first longitudinal beam 110 and a second longitudinal beam 120 , and the electromagnetic isolation assembly 600 is connected between the first longitudinal beam 110 and the second longitudinal beam 120 .

[0089] In this embodiment, the electromagnetic isolation assembly 600 is connected between the first longitudinal beam 110 and the second longitudinal beam 120, which can fully utilize the space in the middle of the frame 100 and improve the space utilization rate of the frame 100. In addition, it can also enhance the structural strength of the frame 100 to a certain extent, thereby reducing the deformation and twisting of the longitudinal beams, thereby improving the safety of the vehicle.

[0090] It should be noted that in order to ensure the isolation effect of the electromagnetic isolation component 600, the height of the electromagnetic isolation component 600 can be set to be higher than the height of any one of the high-voltage component 400 and the low-voltage component 500, so that the electromagnetic isolation component 600 has a better isolation effect on the high-voltage component 400 and the low-voltage component 500.

[0091] In some embodiments, see Figure 1 and Figure 2 The chassis assembly of the vehicle further includes a first axle 700 and a second axle 800 , and the first axle 700 and the second axle 800 are both disposed on the vehicle frame 100 .

[0092] The power battery assembly 200 includes a first power battery pack 210 and a second power battery pack 220 . The first power battery pack 210 and the second power battery pack 220 are respectively arranged on both sides of the frame 100 . The first power battery pack 210 and the second power battery pack 220 are both located between the first axle 700 and the second axle 800 .

[0093] The extended-range fuel assembly 300 includes a first fuel tank 310 and a second fuel tank 320 . The first fuel tank 310 and the second fuel tank 320 are respectively disposed on both sides of the vehicle frame 100 . The first fuel tank 310 and the second fuel tank 320 are both located between the first axle 700 and the second axle 800 .

[0094] In this embodiment, by arranging the first power battery pack 210, the second power battery pack 220, the first fuel tank 310, and the second fuel tank 320 between the first axle 700 and the second axle 800, the weight of each power battery pack and fuel tank is concentrated in the center of the vehicle, helping to maintain vehicle balance. This arrangement also provides better protection for the power battery packs and fuel tanks, preventing them from being crushed in front or rear collisions, thereby improving vehicle safety.

[0095] By arranging the first power battery pack 210 and the second power battery pack 220 on either side of the vehicle frame 100, and the first fuel tank 310 and the second fuel tank 320 on either side of the vehicle frame 100, the vehicle's center of gravity is lowered and its stability is improved. Furthermore, this arrangement fully utilizes the space on both sides of the vehicle frame 100, improving the vehicle's space efficiency. This allows for the installation of larger power battery packs and fuel tanks within the limited space available, thereby increasing the vehicle's range. Furthermore, this arrangement better balances the vehicle's weight, ensuring that the counterweight on both sides of the vehicle frame 100 is substantially uniform, thereby improving vehicle stability.

[0096] It should be noted that both the first power battery pack 210 and the second power battery pack 220 have existing structural designs in the art and will not be described in detail herein.

[0097] Furthermore, the range-extending fuel assembly 300 is a methanol assembly or a methanol-gasoline assembly.

[0098] As a clean energy source, methanol burns more completely, producing fewer pollutants and helping to reduce vehicle emissions. Furthermore, its high energy density allows for extended range. Furthermore, methanol is relatively safe to produce and store, enhancing overall vehicle safety. Methanol-gasoline components combine the advantages of both methanol and gasoline, enabling flexible switching between fuels under varying operating conditions, further improving vehicle adaptability and economy.

[0099] In some embodiments, see Figure 2 The chassis assembly of the vehicle also includes: a cooling assembly 102, the cooling assembly 102, the range extender 101, the high-pressure assembly 400 and the low-pressure assembly 500 are sequentially arranged on the frame 100; a methanol heater 103 and an intake and exhaust assembly 104, the methanol heater 103 and the intake and exhaust assembly 104 are respectively located on both sides of the frame 100; a steering assembly 105, the steering assembly 105 is connected to the frame 100, and the steering assembly 105 and the methanol heater 103 are located on the same side of the frame 100.

[0100] In this embodiment, the cooling assembly 102, the range extender 101, the high-voltage assembly 400 and the low-voltage assembly 500 are relatively small in size. These components are concentrated on the frame 100, that is, the middle part of the vehicle, making the entire vehicle layout more compact and improving the space utilization of the vehicle.

[0101] In low-temperature conditions, it is difficult for a methanol-range extended vehicle to start directly. In this embodiment, a methanol heater 103 is provided to preheat the range extender 101. When the range extender 101 reaches a certain temperature, the range extender 101 can start normally.

[0102] Placing the methanol heater 103 and intake / exhaust assembly 104 on either side of the vehicle frame 100, and the steering assembly 105 and methanol heater 103 on the same side of the vehicle frame 100, helps lower the vehicle's center of gravity and improves its stability. Furthermore, this arrangement fully utilizes the space on either side of the vehicle frame 100, improving the vehicle's space utilization. Furthermore, this arrangement better balances the vehicle's weight, ensuring that the counterweights on both sides of the vehicle frame 100 are substantially consistent, thereby improving vehicle stability.

[0103] In other embodiments, see Figures 1 to 3 The first axle 700 of the vehicle's chassis assembly is an electric drive axle assembly, which includes: an electric drive axle 710, which is arranged on the first longitudinal beam 110 of the frame 100 and the second longitudinal beam 120 of the frame 100; a motor bracket 720, which is connected between the first longitudinal beam 110 and the second longitudinal beam 120, and the motor bracket 720 is connected to the electric drive axle 710; a drive motor (not shown), which is arranged on the motor bracket 720, and the drive motor is connected to the electric drive axle 710; a motor controller 730, the range extender 101, the high-voltage component 400, the low-voltage component 500 and the motor controller 730 are arranged in sequence on the frame 100, and the motor controller 730 is connected to the drive motor.

[0104] The motor bracket 720 is connected to the first longitudinal beam 110 , the second longitudinal beam 120 and the electric drive bridge 710 at the same time to form a closed-loop structure, thereby improving the structural stability of the entire electric drive bridge assembly.

[0105] Placing the drive motor directly on the motor bracket 720 and connecting it to the electric drive axle 710 shortens the power transmission path, reduces transmission losses, and improves the vehicle's power efficiency. Furthermore, this layout allows the drive motor, motor bracket 720, and electric drive axle 710 to form a single unit, enhancing the structural stability of the entire electric drive axle assembly.

[0106] The range extender 101, high-voltage component 400, low-voltage component 500 and motor controller 730 are relatively small in size. These components are concentrated on the frame 100, that is, the middle part of the vehicle, making the entire vehicle layout more compact and improving the space utilization of the vehicle.

[0107] Furthermore, the range extender 101, acting as a heat source, is placed at the front end of the vehicle frame 100, facilitating heat dissipation. The motor controller 730 is placed at the rear end of the vehicle frame 100, close to the drive motor, shortening the transmission distance of the control signal and improving control accuracy and response speed.

[0108] In some embodiments, see Figure 3 The motor bracket 720 includes a bracket body 721, which is used to place the drive motor. The bracket body 721 has a first connecting portion 722, a second connecting portion 723, a third connecting portion 724 and a fourth connecting portion 725 that are spaced apart. The first connecting portion 722 is connected to the first longitudinal beam 110, the second connecting portion 723 is connected to the second longitudinal beam 120, and the third connecting portion 724 and the fourth connecting portion 725 are both connected to the electric drive bridge 710.

[0109] The bracket body 721 serves as an installation base for the drive motor and provides a stable support structure for the drive motor.

[0110] By providing four spaced-apart connection portions, the vehicle frame 100 and the electric drive axle 710 form a four-point connection with the bracket body 721 , thereby enhancing the connection strength and stability between the motor bracket 720 and the vehicle frame 100 and the electric drive axle 710 .

[0111] In addition, the bracket body 721 is connected to the first longitudinal beam 110 through the first connecting portion 722, and is connected to the second longitudinal beam 120 through the second connecting portion 723, so that the bracket body 721 is located between the first longitudinal beam 110 and the second longitudinal beam 120, and the space between the first longitudinal beam 110 and the second longitudinal beam 120 can be fully utilized to arrange the drive motor, thereby improving the space utilization of the vehicle.

[0112] In some specific implementations (not shown in the figures), the first axle 700 further includes a first connecting member, a second connecting member, a third connecting member, and a fourth connecting member.

[0113] The first connection part 722 has a first connection hole, the second connection part 723 has a second connection hole, the third connection part 724 has a third connection hole, and the fourth connection part 725 has a fourth connection hole; the first longitudinal beam 110 has a fifth connection hole, the second longitudinal beam 120 has a sixth connection hole, and the electric drive bridge 710 has a seventh connection hole and an eighth connection hole.

[0114] The first connecting member passes through the first connecting hole and the fifth connecting hole in sequence to connect the first connecting part 722 and the first longitudinal beam 110; the second connecting member passes through the second connecting hole and the sixth connecting hole in sequence to connect the second connecting part 723 and the second longitudinal beam 120; the third connecting member passes through the third connecting hole and the seventh connecting hole in sequence to connect the third connecting part 724 and the electric drive bridge 710; the fourth connecting member passes through the fourth connecting hole and the eighth connecting hole in sequence to connect the fourth connecting part 725 and the electric drive bridge 710.

[0115] It should be noted that the embodiments of the present application do not limit the specific types of the connecting members and the connecting holes, and can be adjusted according to specific needs. For example, each connecting member can be a screw, rivet or bolt assembly, and each connecting hole can be a threaded hole or a through hole.

[0116] In other embodiments, see Figure 3 The first axle 700 further includes a shift execution controller 740 connected to the motor controller 730 . The shift execution controller 740 is disposed on the first longitudinal beam 110 or the second longitudinal beam 120 .

[0117] The first longitudinal beam 110 and the second longitudinal beam 120 serve as the main load-bearing structures of the frame 100 and have high rigidity and stability. Installing the shift execution controller 740 on the first longitudinal beam 110 or the second longitudinal beam 120 can provide a stable installation foundation for the shift execution controller 740, effectively reducing the impact of vibration during vehicle driving on the shift execution controller 740.

[0118] Secondly, positioning the shift controller 740 on the first longitudinal beam 110 or the second longitudinal beam 120 eliminates the need for the controller to occupy valuable space in the center of the vehicle, leaving more room for the placement of other components. Furthermore, positioning the shift controller 740 on the first longitudinal beam 110 or the second longitudinal beam 120, close to the drive motor, shortens the transmission distance of control signals, improving control accuracy and response speed.

[0119] Furthermore, the number of the drive motors is two, and correspondingly, the number of the motor controller 730 and the number of the shift execution controller 740 are both two. The two drive motors can improve the driving efficiency and the braking energy recovery efficiency.

[0120] An embodiment of the present application also provides an extended-range vehicle, comprising a chassis assembly of any of the aforementioned vehicles and a vehicle body arranged on the chassis assembly of the vehicle.

[0121] Specifically, the extended-range vehicle of this embodiment adopts all the technical solutions of the chassis assembly of any of the aforementioned vehicles, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described one by one here.

[0122] It should be understood that the embodiments of the present application are not limited to the precise structures described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present application is limited only by the appended claims.
