It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0033] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of the present application are described from the angles shown in the drawings and should not be construed as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that one component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component.
[0034] This embodiment discloses a vehicle, which includes a vehicle body, multiple wheels, a range extender, a power battery, and a drive system. The multiple wheels are respectively connected to the vehicle body. The range extender, the drive system, and the power battery are respectively arranged on the vehicle body. The range extender includes a fuel tank, an engine, a generator, and a generator control device. The engine is connected to the fuel tank and is used to convert fuel into mechanical energy. The generator is respectively connected to the engine, the drive system, and the power battery, and is used to convert the mechanical energy of the engine into electrical energy and supply it to the drive system and the power battery. The generator control device is connected to the generator and is used to control the operation of the generator. The power battery is respectively connected to the generator control device and the drive system, and is used to control the operation of the drive system and supply power to the generator control device when the range extender is started. The drive system is connected to the multiple wheels and is used to receive the energy from the range extender or the power battery to drive the multiple wheels to move.
[0035] Among them, the vehicle is an extended-range electric vehicle. Extended-range electric vehicles generally have two driving modes: pure electric mode and extended-range mode. When the state of charge of the power battery (the state of charge is the ratio of the remaining capacity of the battery after being used for a period of time or left unused for a long time to its fully charged capacity, usually expressed as a percentage. Its value range is 0 to 1. When the state of charge is 0, it means the battery is fully discharged, and when the state of charge is 1, it means the battery is fully charged) is relatively high, the pure electric mode is adopted, and the power battery supplies power to the drive system, which is equivalent to a pure electric vehicle; when the state of charge value is lower than the set lower limit value, the range extender starts, and the power battery supplies power to the generator control device to drive the generator to start the engine. After the engine starts, the range extender switches to the power generation mode, and the generator converts the energy generated by the engine into electrical energy and supplies it to the drive system, and stores the excess electrical energy in the power battery to charge the power battery. In addition, when the vehicle needs a large amount of power under working conditions such as sudden acceleration, and neither the power battery nor the range extender can meet the demand alone, the power battery and the range extender jointly supply power to the drive system to meet the vehicle performance requirements.
[0036] Referring to Figure 1 , Figure 2 and Figure 3 as shown, Figure 1 is an exploded view of the generator control device provided by an embodiment of the present application, Figure 2 is an exploded view of the generator control device from another perspective provided by an embodiment of the present application, Figure 3 is a cross-sectional view of the generator control device provided by an embodiment of the present application. The generator control device includes a first housing 1, a filter assembly 2 and a heat conduction assembly 3. The first housing 1 is provided with a cooling duct 11 for the cooling medium to flow through. The filter assembly 2 is arranged inside the first housing 1, and the filter assembly 2 includes a second housing 21. The second housing 21 is connected to the first housing 1. The filter assembly 2 is used for filtering the electrical energy output by the generator to eliminate the harmonics and noise therein, so as to ensure the stability and safety of the power system. One end of the heat conduction assembly 3 abuts against the outer surface of the second housing 21, and the other end of the heat conduction assembly 3 abuts against the outer wall of the cooling duct 11, so that the second housing 21 exchanges heat with the cooling medium through the heat conduction assembly 3. Among them, the heat conduction medium can be water or freon, etc.
[0037] In this embodiment, the cooling duct 11 and the first housing 1 are integrally formed for convenient processing, and the heat of the first housing 1 can be directly exchanged with the cooling medium in the cooling duct 11, improving the heat dissipation efficiency of the generator control device. It can be understood that in other embodiments, the cooling duct 11 and the first housing 1 can also be separately arranged.
[0038] In this embodiment, the shortest distance between the side of the cooling pipe 11 close to the second housing 21 and the second housing 21 is L, where 1.8 mm ≤ L ≤ 3 mm, to reduce the situation where the heat conduction component 3 cannot be accommodated due to too short a distance and the situation where the heat transfer efficiency is low due to too large a distance, ensuring the heat conduction efficiency of the heat conduction component 3. Specifically, L can be 1.9 mm, 2.3 mm, 2.6 mm, 2.9 mm, etc.
[0039] This embodiment is provided with a heat conduction component 3. One end of the heat conduction component 3 abuts against the outer surface of the second housing 21, and the other end of the heat conduction component 3 abuts against the outer wall of the cooling pipe 11. When the generator control device generates heat during operation, the heat can be conducted by the second housing 21 to the cooling pipe 11 through the heat conduction component 3 and exchange heat with the cooling medium in the cooling pipe 11, improving the rate of heat transfer, thereby improving the heat dissipation efficiency of the generator control device and the service life of each component, enabling the generator control device to withstand the temperature rise caused by high power and high speed when starting the range extender, so that the range extender can meet higher power requirements.
[0040] Continue to refer to Figures 1-3 As shown, the heat conduction component 3 includes a first heat conduction member 31 and a second heat conduction member 32. The first heat conduction member 31 is disposed on the first housing 1 and located on the outer wall of the cooling pipe 11. The second heat conduction member 32 is disposed on the second housing 21, and the second heat conduction member 32 abuts against the first heat conduction member 31, so that heat can be directly conducted to the first heat conduction member 31 through the second heat conduction member 32 and exchange heat with the cooling medium in the cooling pipe 11, improving the rate of heat transfer.
[0041] In this embodiment, the material of the first heat conduction member 31 is aluminum. Aluminum has a low cost and good heat conduction performance. Aluminum has good formability and can be made into various complex shapes to meet the requirements of different applications, improving the heat conduction efficiency, and thus improving the heat dissipation efficiency of the engine control device. It can be understood that in other embodiments, the first heat conduction member 31 can also be made of other materials, such as copper, graphene, etc.
[0042] In this embodiment, the material of the second heat conduction member 32 is silica gel. Silica gel has a high thermal conductivity and can quickly absorb and dissipate heat, thus quickly and effectively conducting the heat inside the generator control device to the cooling pipe 11 and exchanging heat with the cooling medium in the cooling pipe 11, improving the heat dissipation efficiency. And the heat-conducting silica gel has good insulation properties and can prevent current leakage of the components inside the generator control device, thereby preventing damage to the generator control device. It can be understood that in other embodiments, the second heat conduction member 32 can also be made of other materials, such as rubber, silicone tape, etc.
[0043] In this embodiment, the first heat conducting member 31 is detachably connected to the outer wall of the cooling pipe 11. The first heat conducting member 31 and the cooling pipe 11 can be connected by bolts or snap connections, etc., to facilitate the disassembly, assembly and replacement of the first heat conducting member 31, thereby reducing the situation where the heat transfer efficiency is reduced due to wear of the first heat conducting member 31 after long-term use. It can be understood that in other embodiments, the first heat conducting member 31 can also be connected to the outer wall of the cooling pipe 11 by welding, or the first heat conducting member 31 can also be integrally formed with the outer wall of the cooling pipe 11.
[0044] In this embodiment, the first heat conducting member 31 and the second heat conducting member 32 are connected by bonding to reduce the offset when the first heat conducting member 31 and the second heat conducting member 32 are in contact, thereby ensuring the stability and reliability of heat transfer between the first heat conducting member 31 and the second heat conducting member 32. It can be understood that in other embodiments, the first heat conducting member 31 and the second heat conducting member 32 can also be connected by bolts or snap connections, etc.
[0045] Refer to Figure 3 As shown, the cross-section of the cooling pipe 11 is circular. One side of the first heat conducting member 31 facing the cooling pipe 11 is provided with an abutting surface 310. The abutting surface 310 abuts against the outer wall of the cooling pipe 11, and the abutting surface 310 is arc-shaped to increase the contact area between the first heat conducting member 31 and the cooling pipe 11, so that the first heat conducting member 31 and the cooling pipe 11 are in full contact, thereby further improving the heat exchange efficiency.
[0046] In this embodiment, the cross-section of the cooling pipe 11 is circular. The inner cavity of the circular pipe is smooth and clean, forming a boundary layer, enhancing the heat exchange effect, and the cooling medium will not be subject to too much local resistance when flowing, enabling the heat exchange work to proceed smoothly. It can be understood that in other embodiments, the cross-section of the cooling pipe 11 can also be square, and the shape of the abutting surface 310 is correspondingly set with the shape of the outer wall of the cooling pipe 11.
[0047] Refer to Figure 4 As shown, Figure 4 This is a schematic structural diagram of the filter component of the generator control device provided by the embodiment of the present application. The second housing 21 is provided with a limiting groove 210. The second heat conducting member 32 abuts against the inner wall of the limiting groove 210. The second heat conducting member 32 is limited by the limiting groove 210 to reduce the offset of the second heat conducting member 32, thereby ensuring the stability of heat conduction of the second heat conducting member 32. One end of the first heat conducting member 31 abuts against one side of the second heat conducting member 32, and the other end of the first heat conducting member 31 is connected to the outer wall of the cooling pipe 11.
[0048] In this embodiment, a heat dissipation through hole 210a is formed in the bottom wall of the limiting groove 210, so that the heat of each device can also be directly conducted to the second heat conducting member 32 through the heat dissipation through hole 210a, thereby further improving the heat transfer rate. The heat dissipation through hole 210a is square, and the shape of the heat dissipation through hole 210a corresponds to the shape of the second heat conducting member 32, so that heat can be evenly conducted to the second heat conducting member 32 through the heat dissipation through hole 210a, reducing the situation where the local overheating of the second heat conducting member 32 affects the heat dissipation effect. It can be understood that in other embodiments, the shape of the heat dissipation through hole 210a can also be circular or polygonal, etc.
[0049] In this embodiment, the thickness D of the second heat conducting member 32 satisfies 2.4 mm ≤ D ≤ 3.6 mm, so as to reduce the situation that the second heat conducting member 32 is too thin and prone to breakage, and reduce the situation that the second heat conducting member 32 is too thick and has a large thermal resistance, resulting in a longer time required for heat conduction and reducing the heat conduction effect. Specifically, the thickness D of the second heat conducting member 32 can be 2.5 mm, 2.9 mm, 3.1 mm, 3.4 mm, etc.
[0050] In this embodiment, the second heat conducting member 32 is connected to the inner wall of the limiting groove 210 by an adhesive method to reduce the situation of the second heat conducting member 32 shifting, and ensure the stability and reliability of the heat conduction of the second heat conducting member 32. It can be understood that in other embodiments, the second heat conducting member 32 can also be bolted or snap-connected to the inner wall of the limiting groove 210, or the second heat conducting member 32 can also be arranged in interference fit with the limiting groove 210, that is, the area of the second heat conducting member 32 is larger than the cross-sectional area of the limiting groove 210. During installation, the second heat conducting member 32 needs to be compressed and then placed in the limiting groove 210.
[0051] In this embodiment, there are two limiting grooves 210, and the two limiting grooves 210 are respectively distributed at intervals along the width direction of the second housing 21. The number of the second heat conducting members 32 corresponds to the number of the limiting grooves 210, and each second heat conducting member 32 is respectively arranged in each limiting groove 210. The number of the first heat conducting members 31 corresponds to the number of the second heat conducting members 32, and each first heat conducting member 31 is respectively connected to the outer wall of the cooling pipe 11, and each first heat conducting member 31 is respectively connected to each second heat conducting member 32 to improve the heat dissipation efficiency. It can be understood that in other embodiments, the number of the limiting grooves 210 can also be only one, or three or more than three, and the first heat conducting member 31 can also be only one, and one first heat conducting member 31 is respectively connected to each second heat conducting member 32.
[0052] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application.
