[0002] In motor vehicles equipped with internal combustion engines, the intake system is a core component of the drive system, and its core function is to guide the air in the environment to the engine intake port. Specifically, the intake system is responsible for introducing the outside air into the intake system for internal processing, and delivering the filtered air to the engine. The intake system is usually arranged in the engine compartment. However, in modern vehicle designs, the engine compartment space needs to accommodate a large-capacity engine and integrate more diverse auxiliary equipment.

Thus, the features defined with "first", "second", "third", "fourth", "fifth", and "sixth" may explicitly or implicitly include one or more of such features.

[0053] In the embodiments of the present application, the term "comprise", "include" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

"Equal" includes absolute equality and approximate equality, and the acceptable deviation range for approximate equality can be, for example, that the difference between the two equal ones is less than or equal to 5% of either one.

[0056] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a vehicle 1000 provided by the embodiments of the present application. The vehicle 1000 includes a vehicle body 100 and wheels 200. The vehicle body 100 is for the driver and passengers to ride in and carry items, and the wheels 200 are installed below the vehicle body 100, for carrying the vehicle body 100 and capable of rolling on the road surface so that the vehicle 1000 can travel.

[0057] The vehicle 1000 includes a drive assembly 300, and the drive assembly 300 is located in the engine compartment 500 and is adapted to provide driving force for the vehicle.

[0058] The drive assembly 300 includes: an engine 301 and an intake system 302. The engine 301 is the core component of the vehicle, is connected to the wheels 200, and is a device for providing driving force for the vehicle, generally an internal combustion engine, and in new energy vehicles, it can also be an electric motor.

[0059] The intake system 302 is an important part of the vehicle. The intake system 302 can be arranged in the engine compartment 500, with one end connected to the outside air and the other end connected to the engine 301. The main function of the intake system 302 is to provide sufficient air for the engine 301 to operate normally.

[0060] Please refer to Figure 1 and Figure 2 , Figure 2 FIG. shows a schematic structural diagram of an intake system 302 provided by an embodiment of the present application, including: a fan housing 10 and an intake assembly 20. The fan housing 10 is arranged in the engine compartment 500, connected to the fan 30, and adapted to support the fan 30. At least a part of the intake assembly 20 is formed on the fan housing 10, and the intake assembly 20 is adapted to communicate with the engine 301.

[0061] In this way, by forming at least a part of the intake assembly 20 on the fan housing 10, there is no need to separately arrange the intake assembly 20, which can effectively reduce the occupied volume of the intake system 302 and facilitate the layout optimization of the engine compartment 500.

[0062] It can be understood that canceling the separately arranged intake assembly 20 can also reduce the vehicle production process and improve production efficiency.

[0063] In some embodiments of the present application, the intake system 302 further includes a fan 30. The fan 30 is arranged on the fan housing 10, and the intake assembly 20 is located on the outer peripheral side of the fan 30.

[0064] The fan 30 is an important part of the cooling system. The fan 30 actively promotes air flow mechanically or electrically to cool components such as the electronic control assembly 400. Optionally, the fan 30 can be a turbocharged fan 30, an electric auxiliary intake fan 30, etc., which is not limited in the present application.

[0065] It should be noted that at least a part of the intake assembly 20 is integrated on the fan housing 10, which can reduce the occupied space of the intake system 302 and optimize the layout of the engine compartment 500.

[0066] Please refer to Figure 2 and Figure 3 , Figure 3 shows the air flow path structure diagram of the intake system 302 in the embodiment of the present application Figure 2 In some embodiments of the present application, the fan housing 10 includes: a base body 11, located on the outer peripheral side of the fan 30; an air inlet duct 101 is formed in the base body 11, and the air inlet duct 101 constitutes at least a part of the intake assembly 20. The fan 30 is connected to the base body 11.

[0067] In this way, the base 11 located on the outer peripheral side of the fan 30 forms part of the air intake assembly 20, and there is no need to set up a separate independent air intake assembly 20, which effectively reduces the space occupied by the air intake system 302 and improves the space utilization of the engine compartment 500.

[0068] In addition, in the prior art, the air intake duct 101 of the air intake assembly 20 is usually composed of an air intake braided tube, which is made of a porous material. This also means that the air in the air intake braided tube will exchange gas with the air in the engine compartment. For some compact models such as small cars, the engine compartment space is limited and heat is easily accumulated. Under certain working conditions, it is very likely to heat the intake air flow in the braided tube, causing the temperature of the air flow flowing into the engine to be too high, thereby affecting the engine power.

[0069] It can be understood that in the embodiment of the present application, the air inlet duct 101 constitutes part of the air inlet assembly 20, and there is no need to set an air inlet braided tube, which avoids the heat exchange between the intake air flow in the engine compartment and the outside world, causing the air flow temperature to rise and affecting the occurrence of engine power problems.

[0070] See also Figure 3 and Figure 4 , Figure 4 For the embodiment of this application Figure 2 The schematic diagram of the structure of a part of the air intake system 302 including the air filter 21 is shown in FIG. In some embodiments of the present application, the air intake assembly 20 further includes an air filter 21 , which is disposed in the air intake duct 101 and is suitable for filtering the gas flowing through the air intake duct 101 .

[0071] The air filter 21 is a filtering device installed in the intake system 302 , which intercepts impurities such as dust, sand, metal debris, etc. in the air to prevent them from entering the engine 301 , thereby protecting the engine 301 .

[0072] It is understandable that the air filter 21 is disposed in the air inlet duct 101, and there is no need to provide an independent air filter 21, which can effectively save the engine compartment space.

[0073] In some embodiments of the present application, the air intake assembly 20 further includes a muffler assembly 22 , at least a portion of which is disposed in the air intake duct 101 and is located on the air outlet side of the air filter 21 .

[0074] When the air intake system 302 is working, air flows through the air intake assembly 20 at high speed to the engine 301. The air flow inside the air intake assembly 20 will generate noise due to vibration and turbulence, affecting the driving experience. In order to optimize the driving experience, the air intake system 302 is usually equipped with a muffler assembly 22.

[0075] Optionally, the muffler assembly 22 can be a partition board with holes, which reduces noise generation by reducing air flow vibration.

[0076] Since the muffler assembly 22 is at least partially disposed in the air inlet duct 101, the flowing air in the air intake assembly 20 can fully flow through the muffler assembly 22. In this way, both the working efficiency of the muffler assembly 22 is increased and the engine compartment space can be saved.

[0077] Please refer to Figure 3 、 Figure 5 and Figure 6 , Figure 5 which is a schematic structural diagram of the cover 12 of the air intake system 302 in the embodiment of the present application, Figure 2 and Figure 6 which is a schematic structural diagram of the housing 13 of the air intake system 302 in the embodiment of the present application. In some embodiments of the present application, the base body 11 includes: a cover 12 and a housing 13. A first air duct 121 and a second air duct 122 are formed in the cover 12 at intervals. An air inlet 123 communicating with the first air duct 121 and an air outlet 124 communicating with the second air duct 122 are provided on the cover. There is a receiving chamber 14 in the housing 13, and a first opening 147 communicating with the receiving chamber 14 is provided on the housing 13. The cover 12 is covered at the first opening 147 so that the receiving chamber 14 communicates with both the first air duct 121 and the second air duct 122. The muffler assembly 22 is disposed in the second air duct 122. The air filter 21 is disposed in the receiving chamber 14. Figure 2

[0078] Among them, the first air duct 121 and the second air duct 122 are arranged at intervals in the cover 12 to make the air flow smooth in the air inlet duct 101. The first air duct 121 communicates with the air inlet 123 to guide the outside air entering the air intake system 302 from the air inlet 123 to other parts of the air intake system 302. The second air duct 122 communicates with the air outlet 124 to guide the processed air out of the air intake system 302 and flow to the engine. Thus, by separating the first air duct 121 from the second air duct 122, the mixing interference of air flows at different stages can be avoided and the energy loss can be reduced.

[0079] In addition, a receiving chamber 14 and a first opening 147 communicating with the receiving chamber 14 are provided on the housing 13. The receiving chamber 14 can store air and can also accommodate some components of the air intake system 302. The setting of the receiving chamber 14 provides space for integrating the air intake system 302.

[0080] ​In addition, the housing 13 and the cover 12 cooperate with each other through the opening to form the base 11, and the accommodating chamber 14 is connected with the first air duct 121 and the second air duct 122 through the first opening 147, forming part of the air inlet duct 101. Therefore, the air in the air intake system 302 can enter from the air inlet 123, flow through the first air duct 121, the accommodating chamber 14, the second air duct 122 to the air outlet 124, and flow to the engine, forming a one-way air flow passage, which can avoid airflow backflow or turbulence, and improve the overall efficiency of the air intake system 302.

[0081] It should be noted that the muffler assembly 22 is disposed in the second air duct 122 so that the airflow in the air intake system 302 is fully silenced before flowing out of the air outlet 124, thereby reducing the impact of noise on driving.

[0082] In addition, the air filter 21 is disposed in the accommodating chamber 14 and constitutes a part of the base 11 , so there is no need to additionally provide the air filter 21 , thus saving space in the engine compartment.

[0083] In some embodiments of the present application, the base 11 also includes an air guide plate 17, which is connected to the shell 13 and is arranged in the accommodating chamber 14 to divide the accommodating chamber 14 into a third air duct 141 and an accommodating chamber 142 that are connected to each other. The third air duct 141 is connected to the first air duct 121, and the accommodating chamber 142 is connected to the second air duct 122. The air filter 21 is arranged in the accommodating chamber 142.

[0084] It should be noted that the air guide plate 17 is disposed in the accommodating chamber 14 , and the air flowing into the accommodating chamber 14 can flow along a certain path, that is, through the third air duct 141 to the accommodating cavity 142 .

[0085] In addition, the air filter 21 is disposed in the accommodating chamber 142 so that the air flowing into the accommodating chamber 142 can be fully filtered by the air filter 21. The risk of unfiltered air bypassing the edge of the air filter 21 is reduced, ensuring that the air enters the engine 301 after being filtered.

[0086] In some embodiments of the present application, the third air duct 141 and the accommodating cavity 142 are connected via an avoidance hole 143 , and the avoidance hole 143 is located on a side of the air guide plate 17 away from the cover body 12 .

[0087] It is understandable that the air guide plate 17 does not completely separate the third air duct 141 from the accommodating chamber 142, and the third air duct 141 and the accommodating chamber 142 are connected through the avoidance hole 143. The avoidance hole 143 is located on the side of the air guide plate 17 away from the cover body 12, that is, away from the first air duct 121. The air guide plate 17 guides the air flowing into the accommodating chamber 14 to flow through the first air duct 121, the third air duct 141, the avoidance hole 143, the accommodating chamber 142, and the second air duct 122.

[0088] Thus, the outside air enters the intake system 302 and flows through the first air duct 121, the third air duct 141 to the avoidance hole 143, and then, under the restriction of the outer wall of the accommodation chamber 14, quickly turns through the avoidance hole 143 and enters the accommodation cavity 142. During this process, the outside impurities and moisture, due to their greater specific gravity than air, most of the particulate matter and moisture will be intercepted and collected at the avoidance hole 143 under the action of inertia, which is equivalent to having a pre-purification process before the action of the air filter 21, greatly reducing the loss of the air filter 21, improving the purification effect of the system and the service life of the air filter 21.

[0089] In some embodiments of the present application, a drainage channel 146 communicating with the third air duct 141 is further formed on the housing 13, and one end of the drainage channel 146 communicates with the avoidance hole 143.

[0090] It can be understood that the impurities and moisture intercepted and collected at the avoidance hole 143 can be discharged out of the intake system 302 through the drainage channel 146. The setting of the avoidance hole 143 simply and effectively treats the impurities in the intake system 302, without the need to additionally set a processor for related work, improving the work efficiency.

[0091] In some embodiments of the present application, a first gap 144 is formed between the air filter 21 and the air guiding plate 17, and a second gap 145 is formed between the side of the air filter 21 facing away from the air guiding plate 17 and the inner wall of the housing 13. Both the first gap 144 and the second gap 145 constitute at least part of the air inlet duct 101.

[0092] It should be noted that in the accommodation cavity 142, a first gap 144 exists between the air filter 21 and the air guiding plate 17, and a second gap 145 is formed between the side of the air filter 21 facing away from the air guiding plate 17 and the inner wall of the housing 13. Both the first gap 144 and the second gap 145 constitute at least part of the air inlet duct 101. After the air enters the accommodation cavity 142, it flows to the first gap 144 and the second gap 145, and then enters the air filter 21, forming a dual-path air intake for the air filter 21. When one side gap is blocked by impurities, the other side can still work normally, ensuring the normal smoothness of the air inlet duct 101. In addition, the dual-path air intake increases the cross-sectional area of the air inlet duct 101 of the air filter 21, improving the air circulation efficiency.

[0093] In some embodiments of the present application, a resonance cavity 15 is further formed in the housing 13, and a first opening 151 communicating with the resonance cavity 15 is formed on the housing 13, and the first opening 151 communicates with the first gap 144.

[0094] It should be noted that the resonance cavity 15 is a physical structure that can suppress other unwanted frequencies to indirectly reduce noise. The resonance cavity 15 is disposed within the substrate 11 and communicates with the first gap 144 through the first opening 151. When the gas flows through the first gap 144, a part of it flows into the resonance cavity 15, circulates and vibrates inside the resonance cavity 15, and cancels out the vibration generated by the flowing air in the intake assembly 20, so as to eliminate or subtract the low-frequency noise generated during the operation of the system. Optionally, the size of the resonance cavity 15 can be between 1L and 1.5L, and the present application does not limit this.

[0095] In some embodiments of the present application, the air filter 21 includes: a first filter element 211, which is arranged facing the first gap 144; a second filter element 212, which is arranged at an interval from the first filter element 211 and is arranged facing the second gap 145.

[0096] It can be understood that the filter element is the core component of the air filter 21 and is responsible for directly capturing and removing particulate matter and other pollutants in the air. According to different application requirements and technical levels, the filter element can be made of a variety of materials and adopt different designs to achieve efficient air purification. The filter element usually includes: fiber filter element, activated carbon filter element, multi-layer composite filter element, etc., and the present application does not limit this. The first filter element 211 is arranged facing the first gap 144, and the second filter element 212 is arranged facing the second gap 145, constituting a part of the intake passage. Thus, when one side of the filter element is blocked by impurities, the other side can still work normally, ensuring the normal operation of the air filter 21. In addition, the filter elements on both sides increase the working area of the air filter 21 and improve the filtering efficiency of the air filter 21.

[0097] In some embodiments of the present application, the air filter 21 further includes: a first end cap 213 and a second end cap 214 which are oppositely arranged. The first filter element 211 and the second filter element 212 are connected between the first end cap 213 and the second end cap 214. The first end cap 213 is connected to the cover body 12, and a second opening 216 communicating with the second air duct 122 is formed on the first end cap 213; the second end cap 214 is arranged at the avoidance hole 143.

[0098] It should be noted that the end cap is connected to the filter element, and the first end cap 213 is docked with the second air duct 122 through the second opening 216, and the second end cap 214 is sealed, forming a sealed air flow channel in the accommodation cavity 142, preventing unfiltered air from bypassing the edge of the accommodation cavity 142 and flowing into the second air duct 122. Thus, it can be ensured that all the air flowing in the intake system 302 passes through the purification of the air filter 21, preventing impurities from entering the engine 301 and causing wear of the engine 301.

[0099] In addition, the air flow path in the accommodating cavity 142 is: entering from the avoidance hole 143, blocked by the second end cover 214, flowing to the first gap 144 and the second gap 145, entering the air filter 21 through the first filter element 211 and the second filter element 212, and then flowing into the second air duct 122 through the second opening 216. In this way, the impurities filtered and adsorbed by the air filter 21 are concentrated on the side where the filter element is connected to the second end cover 214, away from the second air duct 122 connected to the engine 301. This arrangement facilitates the replacement of the filter element during use, and reduces the possibility of contamination of the air duct connected to the engine 301 during the replacement of the filter element.

[0100] In some embodiments of the present application, the air filter 21 further includes: a support member 215, the support member 215 is connected between the first end cover 213 and the second end cover 214, and is located between the first filter element 211 and the second filter element 212, and the support member 215 is suitable for supporting the first filter element 211 and the second filter element 212.

[0101] It is understandable that the support member 215 is one of the important components of the air filter 21. The support member 215 is disposed inside the air filter 21, connecting the first end cap 213 and the second end cap 214, the first filter element 211 and the second filter element 212 which are opposite to each other.

[0102] Optionally, the support member 215 may be a mesh frame, which can greatly improve the structural rigidity of the entire air filter 21 and better adapt to high air flow conditions.

[0103] Since the support member 215 is between the first filter element 211 and the second filter element 212 to support the filter element structure, when air flows through the filter element and applies air pressure to the filter element, the support member 215 enables the filter element to maintain a stable shape to avoid damage to the filter layer.

[0104] See also Figure 7 , Figure 7 For the embodiment of this application Figure 2 Schematic diagram of the assembly of the cover 12 and the housing 13 of the air intake system 302. In some embodiments of the present application, a limiting groove 217 is formed on one side of the cover 12 facing the first end cover 213, and the cover 12 is provided with a first limiting portion 125, which is connected to the limiting groove 217.

[0105] It can be understood that the cooperation between the limiting groove 217 and the first limiting portion 125 forms a positioning, thereby ensuring the assembly accuracy between the first end cover 213 and the cover body 12 .

[0106] In some embodiments of the present application, a sealant 40 is disposed in the limiting groove 217 , and the sealant 40 is suitable for sealing the gap between the limiting groove 217 and the first limiting portion 125 .

[0107] It is understandable that to ensure the sealing of the air inlet duct 101, it is necessary to seal the connection part between the cover 12 and the air filtering device 21. Optionally, a sealant 40 can be used for sealing. The sealant 40 forms a continuous sealing layer by filling the connection gap.

[0108] Optionally, the sealant 40 can be a polyurethane (PU) sealant. The sealant 40 is bonded in the corresponding limiting groove of the first end cover 213. After the peripheral circle of the first limiting part 125 extrudes the sealant 40, it accesses the groove of the limiting groove 217. The compressed polyurethane sealant 40 can seal the docking part between the cover 12 and the housing 13. Since the sealant 40 can adapt to complex surface shapes and fill small gaps, it is used for sealing.

[0109] Please refer to Figure 2 and Figure 3 , in some embodiments of the present application, the intake system 302 includes a front end module 50; an inlet 51 is provided on the front end module 50, and the inlet 51 is communicated with the air inlet 123.

[0110] It should be noted that there is a front end module 50 connected to the fan housing 10 in the intake system 302. It is suitable for fixing the fan housing 10 and the intake assembly 20 connected to the fan housing 10 in the engine compartment to ensure the stable position of the intake system 302 in the engine compartment.

[0111] In addition, an inlet 51 communicated with the air inlet 123 is provided on the front end module 50 to form an air path, so that air can normally pass through the front end module 50 and enter the air inlet duct 101.

[0112] In some embodiments of the present application, a sound-absorbing member 60 is provided on the outer wall of the housing 13 forming the accommodation chamber 14.

[0113] Since air will generate vibrations and noises due to air flow vibrations, turbulences and pressure changes when flowing in the accommodation chamber 14. Therefore, a sound-absorbing member 60 is provided on the outer wall of the accommodation chamber 14 to reduce the noise of the intake system 302.

[0114] It is understandable that the sound-absorbing member 60 and the muffler assembly 22 cooperate to provide a complete sound insulation function for the entire intake system 302.

[0115] In some embodiments of the present application, the sound-absorbing member 60 includes a sound-absorbing tile 61.

[0116] The sound-absorbing tile 61 is a material for reducing noise, generally made of materials such as rubber, and has a special microporous structure inside. This structure can effectively absorb and scatter sound waves, reducing the reflection and propagation of sound.

[0117] It is understandable that the sound insulation tile 61 is made of lightweight materials such as rubber and has a relatively low weight. Thus, in addition to meeting the sound insulation requirements of the intake system 302, the sound insulation tile 61 can effectively reduce the total mass of the components.

[0118] Please refer to Figure 3 and Figure 5 In some embodiments of the present application, the cover 12 further includes: a first partition 126 disposed inside the cover 12, and the first partition 126 divides the internal space of the cover 12 into a first air duct 121 and a second air duct 122.

[0119] It is understandable that the first partition 126 divides the space inside the cover 12 into relatively independent first and second air ducts 121 and 122, which can prevent the air inside the cover 12 from forming turbulent flow and improve the efficiency of the intake system 302.

[0120] In some embodiments of the present application, the muffler assembly 22 includes: a second partition 127, and the second partition 127, together with the inner wall of the housing 13 and the first partition 126, encloses a muffling chamber 19. A third opening 128 communicating with the second air duct 122 is formed on the second partition 127; a perforated plate 129 is disposed at the third opening 128.

[0121] The muffler assembly 22 further includes a second partition 127 formed with a third opening 128 and a perforated plate 129. The second partition 127, together with the inner wall of the housing 13 and the first partition 126, encloses a muffling chamber 19. The perforated plate 129 is placed at the third opening 128.

[0122] It should be noted that the muffling chamber 19 is a functional chamber inside the muffler assembly 22 for reducing noise. By controlling the propagation path, reflection, interference or resonance of sound waves in the chamber, the purpose of reducing noise is achieved. Enclosing the muffling chamber 19 by the second partition 127, the inner wall of the housing 13 and the first partition 126 can simplify the structure of the muffler assembly 22, improve the space utilization rate, and reduce the space structure occupied by the intake system 302.

[0123] In addition, the perforated plate 129 also has a guiding function, which can ensure smooth air flow while reducing noise.

[0124] It is understandable that by designing the perforated plate 129 and the second partition 127 with different structures and parameters, the high-frequency sound insulation requirements of most intake systems 302 can be met.

[0125] Please refer to Figure 1 and Figure 8 , Figure 8 shows in the embodiments of the present application Figure 1Schematic assembly structure diagram of the middle air intake system and the electronic control assembly 400 in the engine compartment 500. In some embodiments of the present application, the air intake system 302 further includes: an electronic control assembly 400 disposed on the air outlet side of the fan 30; a guiding inclined surface 18 is formed on the housing 13, and the guiding inclined surface 18 is adapted to guide the air flow blown out by the fan 30 to the location of the electronic control assembly 400.

[0126] It can be understood that the electronic control assembly 400 is disposed in the engine compartment 500 and is located on the air outlet side of the fan 30. When the electronic control assembly 400 is in operation, heat will be generated and a relatively large heat dissipation space is required.

[0127] Since at least part of the air intake component 20 is disposed on the fan housing 10, the overall volume of the air intake system 302 is reduced, enabling the electronic control assembly 400 to obtain a larger heat dissipation space.

[0128] In addition, a guiding inclined surface 18 is provided on the housing 13. When the fan 30 starts to operate, the air flow flows out from the fan blades at a high speed. At this time, a negative pressure area will be formed between the guiding inclined surface 18 of the housing 13 and the air flow. Under the action of the negative pressure, more air flow will flow along the guiding inclined surface 18, and thus more external air is introduced into the space around the electronic control assembly 400, improving the heat dissipation effect.

[0129] Please refer to Figure 1 、 Figure 2 and Figure 10 , Figure 10 shows an exploded view of an air intake system 302 provided by an embodiment of the present application. In some embodiments of the present application, the air intake system 302 further includes: an intake pipe 70, one end of the intake pipe 70 is communicated with the air outlet 124, and the other end is adapted to be communicated with the engine 301.

[0130] One end of the intake pipe 70 is connected to the air outlet 124 of the air intake component 20, and the other end is connected to the engine 301. The intake pipe 70 is adapted to guide the filtered clean air in the air intake component 20 into the engine 301 for the normal operation of the engine. The intake pipe 70 is relatively independent of the air intake component 20, facilitating replacement.

[0131] In some embodiments of the present application, the air intake system 302 further includes: a supercharger 80, including an air inlet 81 and an air outlet 82, the air inlet 81 is communicated with the intake pipe 70, and the air outlet 82 is communicated with the engine 301.

[0132] It should be noted that the intake system 302 further includes a supercharger 80. Its intake port 81 is communicated with the intake pipeline 70, and its outlet port 82 is communicated with the engine 301. The supercharger 80 is mainly used to improve the intake efficiency of the engine 301, thereby enhancing the performance of the engine 301. Optionally, there are mainly two types of superchargers 80: a mechanical supercharger 80 and a turbocharger 80. This application does not limit this.

[0133] Please refer to Figure 9 、 Figure 13 and Figure 14 , Figure 9 which shows a schematic structural view of the assembled part of the fan housing 10 and the front end module 50 in the embodiment of the present application, Figure 2 and Figure 13 shows a first schematic structural view of the shock absorption assembly 90 in the embodiment of the present application, Figure 9 and Figure 14 shows a second schematic structural view of the shock absorption assembly in the embodiment of the present application. In some embodiments of the present application, the intake system 302 further includes: a shock absorption assembly 90, and the base body 11 is connected to the front end module 50 through the shock absorption assembly 90. Figure 9

[0134] It should be noted that during the operation of the intake system 302, the air inside flows at a high speed, and the system will generate a certain degree of excited vibration under the action of the air kinetic energy. Therefore, the intake system 302 usually includes a shock absorption assembly 90. The base body 11 is connected to the front end module 50 through the shock absorption assembly 90.

[0135] It can be understood that in order to meet the assembly of the fan housing 10 and the front end module 50, the shock absorption assembly 90 will have various structures. Exemplarily, it may include a first structure of the shock absorption assembly and a second structure of the shock absorption assembly. Different structures are suitable for the assembly requirements of different positions. Optionally, the assembly positions may include: a first position 91 of the shock absorption assembly, a second position 92 of the shock absorption assembly, a third position 93 of the shock absorption assembly, and a fourth position 94 of the shock absorption assembly.

[0136] Since the fan 30 is connected to the base body 11 and at least part of the intake system 302 is arranged on the base body 11, the main vibration of the intake system 302 is concentrated on the base body 11. The shock absorption assembly 90 arranged between the base body 11 and the front end module 50 can effectively reduce the vibration of the intake system 302 from being transmitted to the vehicle body through the front end module 50, thereby affecting the driving experience. It can be understood that multiple shock absorption assemblies 90 work together to meet the overall shock absorption requirements of the intake system to optimize the driving experience.

[0137] Based on the above-described intake system 302, the intake system 302 provided by the embodiment of the present application can at least achieve the following functions:

[0138] Figure 10 Please refer to Figure 10, where an inlet 51 is formed on the front-end module 50, and the front-end module 50 is adapted to be connected to the fan housing 10. The fan housing 10 includes a housing 13 and a cover 12, and the fan housing 10 is adapted to connect to the fan 30. The air filtering device 21 is disposed inside the housing 13 and connected to the cover 12. One end of the intake air pipeline 70 is connected to the cover 12, and the other end is connected to the supercharger 80.

[0139] Please refer to Figure 2 , when the intake system 302 is in operation, the fan 30 rotates to drive the air flow. The air flows through the inlet 51, passes through the front-end module 50, and enters the air inlet 81. The air passes through the first air duct 121 and the second air duct 122, and is first filtered at the avoidance hole 143. Part of the moisture and impurities in the air converge at the bottom of the accommodation chamber 14 under the action of inertia and flow out through the drainage channel 146. The air passing through the avoidance hole 143 enters the accommodation cavity 142, flows towards the first gap 144 and the second gap 145, passes through the first filter element 211 and the second filter element 212, and then enters the interior of the air filter 21, and flows out of the air filter 21 through the second opening 216 and flows towards the second air duct 122. At the same time, part of the air flowing towards the first gap 144 flows into the resonance cavity 15 to reduce the noise generated by the air flow vibration. The air flowing into the second air duct 122 flows through the muffler assembly 22, flows out from the air outlet 124, flows into the intake air pipeline 70, and is guided by the intake air pipeline 70 to enter the engine 301 through the supercharger 80.

[0140] Please refer to Figure 11 , Figure 11 shows a schematic assembly structure diagram of a conventional intake system 302 in the engine compartment. For hybrid vehicles, in the prior art, the intake system 302 is usually installed on the motor or the high-voltage electric control assembly 400 through a bracket. This requires considering the clearance requirements for the assembly of the intake components. In the limited space between the fan housing 10 and the motor electric control assembly 400, there is also a need to leave a clearance space between the air filter 21 and the fan 30; at the same time, when the air filter 21 is installed on the motor or the high-voltage electric control assembly 400, a reserved bracket and assembly space are provided, which is also the width of the heat dissipation air flow channel of the high-voltage electric control.

[0141] Please refer to Figure 12 , Figure 12 shows the schematic assembly structure diagram of the intake system in the engine compartment in the embodiment of the present application Figure 1 . In the embodiment of the present application, the air filter 21 is disposed in the air inlet duct 101. Compared with the prior art, the intake system involved in the embodiment of the present application can effectively reduce the occupied space, and greatly increase the width of the heat dissipation air flow channel of the electric control assembly 400. With the rapid development of the electrification of new energy vehicles, the increase in the heat dissipation space in the area of the electric control assembly 400 means a higher performance ceiling.

[0142] In the description of the embodiments of the present application, specific features, structures, materials, or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0143] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
