DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 7 The air intake device 100 according to an embodiment of the present invention is described. The air intake device 100 includes: a front end module 10 , a guide plate 20 and an air intake extension channel structure 30 .

[0030] like Figure 1-Figure 3 As shown, the front end module 10 is provided with a connecting port 11, and the connecting port 11 is used to connect with the air inlet of the engine; the guide plate 20 is provided on one side of the front end module 10, and the guide plate 20 is formed with a first air inlet 23; the air inlet extension channel structure 30 is sealed and connected with the guide plate 20 and the front end module 10 to define an air inlet sealing cavity, and the air inlet sealing cavity connects the first air inlet 23 and the connecting port 11. In this embodiment, the first direction A is the front-rear direction of the vehicle.

[0031] The front-end module 10 in the air intake device 100 is arranged adjacent to the engine and on the front side of the engine. The guide plate 20 is arranged on the side of the front-end module 10 away from the engine along the first direction A and is connected to the front-end module 10. At least a portion of the guide plate 20 adjacent to the front-end module 10 is provided with a first air inlet 23. At least a portion of the front-end module 10 adjacent to the guide plate 20 is provided with a connecting port 11. One end of the air intake extension channel structure 30 adjacent to the front-end module 10 is connected to the connecting port 11 and a sealing treatment is performed at the connection to achieve a sealed connection. One end of the air intake extension channel structure 30 adjacent to the guide plate 20 is connected to the first air inlet 23 and is sealed. The air intake extension channel structure 30, part of the front-end module 10 and part of the guide plate 20 are enclosed and formed an air intake sealed cavity. External air on the side of the guide plate 20 away from the front-end module 10 enters the air intake sealed cavity through the first air inlet 23 and flows from the connecting port 11 to the air intake of the engine to meet the air intake demand of the engine.

[0032] According to the air intake device 100 of the embodiment of the present invention, by providing the guide plate 20 and forming a good sealing connection between the air intake extension channel structure 30, the guide plate 20 and the front end module 10, it can effectively prevent the high-temperature gas from flowing back or entering the air intake sealing cavity through the gap between the air intake extension channel structure 30 and the guide plate 20 and the front end module 10 and flowing to the engine air intake port, thereby improving the sealing performance of the air intake device 100, reducing the backflow of high-temperature gas of the engine at idle and low speeds, avoiding engine knock due to high intake temperature, and extending the service life of the engine.

[0033] According to some embodiments of the present invention, Figure 3 As shown, the deflector 20 includes: a first connecting plate 21 and a second connecting plate 22, the first connecting plate 21 is sealed and connected to the front end module 10; at least one end of a portion of the second connecting plate 22 is connected to the first connecting plate 21 at the periphery of the first connecting plate 21, and the other end of the second connecting plate 22 extends toward the side of the first connecting plate 21 away from the front end module 10, and the first air inlet 23 is provided on the second connecting plate 22. In this embodiment, the second direction B is the left-right direction of the vehicle, and the third direction C is the height direction of the vehicle.

[0034] Optionally, the front end module 10 is a frame structure, the deflector 20 is arranged on a side of the front end module 10 away from the engine along the first direction A, and the deflector 20 extends along the outer periphery of the front end module 10 to form a semi-enclosed structure. Among them, a side surface of the first connecting plate 21 adjacent to the front end module 10 along the first direction A forms a sealed connection with the front end module 10, the second connecting plate 22 is arranged at an end of the first connecting plate 21 adjacent to the connecting port 11 along the third direction C, and at least a portion of the second connecting plate 22 is arranged on the outer periphery of the first connecting plate 21 and connected to the first connecting plate 21, and at least a portion of the first connecting plate 21 is bent along the first direction A toward a direction away from the front end module 10, so as to form an enclosed structure in the circumferential direction of the front end module 10, and to prevent the air outside the two sides of the deflector 20 along the second direction B from entering the deflector 20.

[0035] Therefore, the design of the guide plate 20 can facilitate the smooth entry of external air from the side of the guide plate 20 away from the front-end module 10 into the guide plate 20, ensuring that the air enters the air intake extension channel structure 30 from the first air inlet 23 and finally enters the engine. In addition, the structural arrangement of the first connecting plate 21 and the second connecting plate 22 facilitates the sealing connection between the guide plate 20 and the front-end module 10, preventing high-temperature gas from flowing back into the guide plate 20 through the gap between the first connecting plate 21 and the front-end module 10. In the non-wading condition of the vehicle, the high-temperature gas can be prevented from entering the engine, further extending the service life of the engine and improving the power economy of the vehicle in the non-wading condition.

[0036] Optionally, the guide plate 20 is an integrally formed part, that is, the first connecting plate 21 and the second connecting plate 22 can be manufactured as a whole, thereby improving the structural strength and reliability of the guide plate 20, reducing the difficulty of processing, and improving the processing efficiency.

[0037] According to some embodiments of the present invention, Figure 1 As shown, the first air inlet 23 penetrates the second connecting plate 22 along the thickness direction of the second connecting plate 22 , ie, the third direction C, and the first air inlet 23 is disposed opposite to an end of the air inlet extension channel structure 30 adjacent to the guide plate 20 .

[0038] The first air inlet 23 penetrates at least a portion of the second connecting plate 22 along the third direction C. The first air inlet 23 and an end of the air inlet extension channel structure 30 adjacent to the guide plate 20 are relatively arranged along the third direction C and are connected to each other. The air guided by the guide plate 20 enters the air inlet extension channel structure 30 through the first air inlet 23 and then flows toward the engine through the connecting port 11.

[0039] Therefore, by relative arrangement of the first air inlet 23 and the end of the air intake extension channel structure 30 adjacent to the guide plate 20, external air on the side of the guide plate 20 away from the front end module 10 can be introduced into the air intake extension channel structure 30 through the first air inlet 23, thereby shortening the air intake path, facilitating air intake, and improving the air intake efficiency of the engine.

[0040] According to some embodiments of the present invention, Figure 1 As shown, the air intake extension channel structure 30 defines an air intake sealing cavity together with the front end module 10 and the guide plate 20. The first air intake port 23 and the connecting port 11 are respectively connected to the air intake sealing cavity. The first air intake port 23 is constructed so that air is suitable for entering the engine through the first air intake port 23.

[0041] That is, the external air on the side of the guide plate 20 away from the front-end module 10 flows along the third direction C through the first air inlet 23 and enters the air inlet sealing cavity of the air inlet extension channel structure 30, then flows into the front-end module 10 through the connecting port 11, and finally enters the engine. At this time, the air transmission path is the first air inlet path. The air inlet extension channel structure 30, the front-end module 10 and the guide plate 20 define an air inlet sealing cavity, which can be understood as when the air inlet extension channel structure 30 is connected to the front-end module 10 and the guide plate 20, a sealing treatment is performed at the connection, and the defined air inlet sealing cavity is connected to other components through the first air inlet 23 and the connecting port 11.

[0042] Therefore, by defining an air intake sealing cavity through the air intake extension channel structure 30, the front end module 10 and the guide plate 20, the loss of air in the air intake extension channel structure 30 can be reduced, and the air intake efficiency of the engine can be improved. At the same time, a complete transmission path is provided for air to enter the engine, thereby better meeting the air intake requirements of the engine.

[0043] According to some embodiments of the present invention, the cross-sectional area of ​​the first air inlet 23 along the air inlet direction gradually increases.

[0044] Optionally, along the path direction of air flowing from the guide plate 20 to the connecting port 11, the cross-sectional area of ​​the end of the first air inlet 23 away from the air inlet sealing cavity is smaller than the cross-sectional area of ​​the end of the first air inlet 23 adjacent to the air inlet sealing cavity. That is, along the third direction C toward the air inlet extension channel structure 30, the cross-sectional area of ​​the first air inlet 23 gradually increases.

[0045] Optionally, there are multiple first air inlets 23 , and the multiple first air inlets 23 extend along the first direction A and are arranged along the second direction B at intervals.

[0046] As a result, the cross-sectional area of ​​the first air inlet 23 along the air intake direction tends to increase, which can increase the air intake amount, thereby improving the efficiency of air entering the engine, thereby improving the working efficiency of the engine.

[0047] According to some embodiments of the present invention, Figure 2 As shown, the air extraction device 100 further includes: a filtering structure 24 , and the filtering structure 24 is disposed at the first air inlet 23 .

[0048] In this embodiment, a filter structure 24 is provided at the first air inlet 23 to further filter the air and ensure the quality of the air intake. In addition, under the premise of ensuring the air intake volume, the filter structure 24 can be a rectangular, circular, mesh or fence structure, and can be specifically provided according to actual needs, which is not limited here.

[0049] Therefore, by setting up a filtering structure 24 to filter impurities in the air entering the first air inlet 23, hay, straw and other debris can be prevented from entering the engine through the first air inlet 23, thereby providing a good air circulation effect for the engine intake, ensuring the normal operation of the engine, protecting the internal components of the engine, extending the service life of the engine, and improving the reliability of the air intake device 100.

[0050] According to some embodiments of the present invention, the air intake extension channel structure 30 is detachably connected to the guide plate 20 .

[0051] In this embodiment, a bolt or screw connection is formed between the end of the air inlet extension channel structure 30 adjacent to the guide plate 20 and the guide plate 20. Therefore, by detachably connecting the air inlet extension channel structure 30 and the guide plate 20, it is convenient to repair or replace the air inlet extension channel structure 30 and the guide plate 20, improve the installation and removal efficiency of the air inlet extension channel structure 30 and the guide plate 20, and reduce the processing technology of the air intake device 100.

[0052] Optionally, the air intake extension channel structure 30 and the guide plate 20 are integrally formed. That is, the air intake extension channel structure 30 and the guide plate 20 can be integrally manufactured. Thus, the structural strength of the air intake device 100 can be improved, the production efficiency of the air intake device 100 can be improved, and the production cost can be reduced.

[0053] According to some embodiments of the present invention, Figure 1 and Figure 5 As shown, the air intake extension passage structure 30 is formed with an opening, and the opening is arranged toward the air guide plate 20 and the front end module 10 .

[0054] In order to better understand the relationship between the air inlet extension channel structure 30, the communication port 11 and the first air inlet 23, Figure 1Only a portion of the air intake extension channel structure 30 is shown, which is covered between the connecting port 11 and the first air intake port 23, and the complete air intake extension channel structure 30 is not shown. One end of the air intake extension channel structure 30 adjacent to the front end module 10 is arranged at the connecting port 11 and connected to the front end module 10, and one end of the air intake extension channel structure 30 adjacent to the guide plate 20 is arranged at the first air intake port 23 and connected to the guide plate 20, and the air intake extension channel structure 30 is open along the third direction C toward the guide plate 20 and the front end module 10.

[0055] Therefore, by optimizing the design of the air intake extension channel structure 30, the cross-sectional area of ​​the air intake extension channel structure 30 can be increased, the air intake resistance of the engine can be reduced, thereby increasing the air intake volume of the engine, improving the output power of the engine, and at the same time reducing the production cost of the air intake extension channel structure 30. The air intake extension channel structure 30 is covered between the connecting port 11 and the first air intake port 23 to improve the sealing performance of the air intake extension channel structure 30.

[0056] According to some embodiments of the present invention, Figure 5 As shown, the air intake extension channel structure 30 includes: a first extension plate 31 and two second extension plates 32, the two second extension plates 32 are arranged on both sides of the first extension plate 31, one end of the two second extension plates 32 are respectively connected to the first extension plate 31, the other ends of the two second extension plates 32 are bent and extended toward the front end module 10, and the other ends of the two second extension plates 32 are respectively sealed and connected to the front end module 10 and the guide plate 20 to define an air intake sealing cavity.

[0057] The first extension plate 31 is arranged in the middle area of ​​the air intake extension channel structure 30, and the two ends of the first extension plate 31 along the first direction A are respectively connected to the front end module 10 and the guide plate 20, and the two second extension plates 32 are respectively connected to the two sides of the first extension plate 31 along the second direction B at one end adjacent to the first extension plate 31 along the third direction C, and the other ends of the two second extension plates 32 are respectively extended and bent along the third direction C toward the adjacent guide plate 20 and the front end module 10, forming a sealed connection between the front end module 10 and the guide plate 20, and the air intake extension channel structure 30 is covered on the front end module 10 and the guide plate 20 and covers the first air inlet 23 and the connecting port 11.

[0058] Therefore, through the arrangement of the first extension plate 31 and the two second extension plates 32 and the sealed connection between the second extension plate 32 and the front end module 10 and the guide plate 20, it is convenient to define an air intake sealing cavity together with the front end module 10 and the guide plate 20, and while connecting the first air inlet port 23 and the connecting port 11, the volume of the air intake sealing cavity can be increased to the greatest extent. At the same time, the sealing performance between the air intake extension channel structure 30 and the front end module 10 and the guide plate 20 can be improved, and high-temperature gas can be prevented from entering the air intake extension channel structure 30 through the gap between the air intake extension channel structure 30 and the front end module 10 and the guide plate 20, thereby preventing the engine from generating knock and improving the sealing performance of the air intake device 100.

[0059] According to some embodiments of the present invention, the guide plate 20 is sealed and connected to the front-end module 10 .

[0060] That is, a sealed connection is formed between the first connecting plate 21 of the guide plate 20 and the front-end module 10. Thus, it is possible to prevent the high-temperature gas from flowing back to the side of the guide plate 20 away from the front-end module 10 through the gap between the first connecting plate 21 and the front-end module 10, thereby improving the sealing and reliability of the gas extraction device 100.

[0061] According to some embodiments of the present invention, the air extraction device 100 further includes: a first sealing member, which is disposed between the guide plate 20 and the front-end module 10 .

[0062] The first seal is arranged between the guide plate 20 and the front-end module 10 along the first direction A, and the first seal is connected to the first connecting plate 21 on one side adjacent to the guide plate 20 along the first direction A, and the first seal is connected to the front-end module 10 on the other side adjacent to the front-end module 10 along the first direction A, and the first seal is adapted to the guide plate 20 and the front-end module 10, and the first seal is suitable for connecting the guide plate 20 and the front-end module 10 at one end adjacent to each other and achieving sealing.

[0063] Optionally, the first sealing member is a sponge strip, a sponge block, or a rubber strip, a rubber block.

[0064] Therefore, by setting a first seal between the guide plate 20 and the front-end module 10, the sealing between the guide plate 20 and the front-end module 10 can be improved, and at the same time, the connection strength between the guide plate 20 and the front-end module 10 can be improved, thereby improving the overall sealing and structural strength of the air intake device 100, improving the reliability of the air intake device 100, and preventing the engine from knocking.

[0065] According to some embodiments of the present invention, Figure 1 and Figure 4As shown, a second air inlet 12 is formed on the front-end module 10 , and the second air inlet 12 is connected to the air inlet sealing cavity; the air extraction device 100 also includes: a cover plate 13 , which is arranged at the second air inlet 12 , and the cover plate 13 is configured to open and close the second air inlet 12 .

[0066] The second air inlet 12 penetrates at least a portion of the front end module 10 adjacent to the connecting port 11 along the third direction C, and the second air inlet 12 is connected to the air inlet sealing cavity of the air inlet extension channel structure 30, and air can enter the air inlet extension channel structure 30 through the second air inlet 12, and flow to the engine from the connecting port 11. The cover plate 13 is arranged at the second air inlet 12 along the third direction C, and the shape and size of the cover plate 13 and the second air inlet 12 are adapted, and the cover plate 13 and the second air inlet 12 are movably matched, and whether the air flows through the second air inlet 12 can be controlled by opening and closing the second air inlet 12.

[0067] Therefore, by setting up a second air inlet 12, and the second air inlet 12 is connected to the air intake sealing cavity, an alternative path is provided for the transmission of air in the air intake device 100, thereby providing an alternative air flow path for the engine, ensuring the normal operation of the engine, meeting the engine's air intake needs in multiple scenarios, and improving the versatility and reliability of the air intake device 100.

[0068] Optionally, the position of the second air inlet 12 may be specifically set according to the structure and layout of the vehicle.

[0069] Optionally, the cover plate 13 may be used as an actuator to execute opening and closing instructions according to parameters such as the monitored water level, so as to realize the opening, closing and opening size adjustment functions of the second air inlet 12 .

[0070] According to some embodiments of the present invention, the cover plate 13 is rotatably connected to the front end module 10 at the second air inlet 12 .

[0071] At least one mounting shaft 132 is respectively provided at both ends of the cover plate 13 along the second direction B. The mounting shaft 132 extends along the second direction B. A mounting hole is formed on the side wall of the second air inlet 12 opposite to the mounting shaft 132 along the second direction B. The mounting shaft 132 can be rotatably connected to the mounting hole around the axial direction of the mounting shaft 132. Thus, the cover plate 13 is rotatably connected to the front end module 10 at the second air inlet 12 to adjust the opening angle of the cover plate 13 and the air intake amount of the engine, so as to meet the air intake requirements of the engine in different application scenarios of the vehicle and reduce driving risks.

[0072] Optionally, the cover plate 13 is movably connected to the front end module 10 at the second air inlet 12. That is, the cover plate 13 can be moved along the second direction B or the first direction A at the second air inlet 12, so as to adjust the opening or closing of the second air inlet 12, and adjust the size of the second air inlet 12 according to different air intake requirements of the engine. On the premise that similar functions can be achieved, the preferred configuration can be made according to the structure of the surrounding structural parts, the spatial arrangement, etc.

[0073] According to some embodiments of the present invention, Figure 4 As shown, the cover plate 13 is formed with a first mating surface 131, and a second mating surface is formed at the edge of the second air inlet 12. The first mating surface 131 and the second mating surface are arranged in parallel, and extend obliquely toward the connecting port 11 along the direction from the second air inlet 12 to the connecting port 11, and the side surface of the cover plate 13 away from the air inlet extension channel structure 30.

[0074] Optionally, the cover plate 13 is respectively formed with first mating surfaces 131 on both sides along the first direction A, and the second air inlet 12 is formed with a second mating surface on one side edge along the first direction A.

At this time, the second mating surface is provided on the side of the second air inlet 12 adjacent to the connecting port 11 and is arranged parallel to the first mating surface 131. At this time, the cover plate 13 is defined as the cover plate 13 flips toward the connecting port 11 to connect the connecting port 11 and the second air inlet 12, and the first mating surface 131 is provided above the second mating surface along the third direction C. Optionally, one end of the cover plate 13 adjacent to the connecting port 11 rotates around the mounting shaft 132 toward the direction of the air inlet extension channel structure 30. When the first mating surface 131 is disposed on the side of the cover plate 13 away from the connecting port 11, the first mating surface 131 is disposed below the second mating surface to ensure that the end of the cover plate 13 adjacent to the connecting port 11 is turned toward the air inlet extension channel structure 30. The first mating surface 131 and the second mating surface are matched in shape and size.

[0075] Therefore, by cooperating between the first mating surface 131 of the cover plate 13 and the second mating surface of the edge of the second air inlet 12, it can be ensured that a good seal is formed with the edge of the second air inlet 12 when the cover plate 13 is closed. In non-wading conditions or when the wading depth is shallow, the cover plate 13 is always in a closed state, and air can flow smoothly from the first air inlet 23 to the connecting port 11, thereby preventing air from flowing out from the first air inlet 23 to the second air inlet 12, and preventing high-temperature air from entering the intake extension channel structure 30 through the gap between the edge of the cover plate 13 and the second air inlet 12, thereby preventing hot air from flowing back and preventing the engine from knocking due to high intake temperature, thereby extending the service life of the engine and improving the power economy of the vehicle in non-wading conditions.

[0076] According to some embodiments of the present invention, the second air inlet 12 is configured such that when the air intake of the first air inlet 23 is blocked, the cover plate 13 is adapted to be opened under the action of engine suction, and air is adapted to enter the connecting port 11 through the second air inlet 12 .

[0077] like Figure 7 As shown, when the vehicle wades through deep water, air cannot enter the air intake extension channel structure 30 from the first air intake port 23. At this time, the cover plate 13 opens the second air intake port 12 under the action of the suction force of the engine. The gas enters the air intake extension channel structure 30 through the second air intake port 12 and flows to the engine from the connecting port 11. The gas transmission path is the second air intake path.

[0078] Therefore, the required air is provided to the engine through the second air intake path to meet the normal operation requirements of the vehicle and the engine, avoid vehicle stalling or water ingress to the engine, improve the safety and reliability of wading driving, increase the vehicle's usage scenarios, and meet more differentiated needs.

[0079] Alternatively, if Figure 6 As shown, when the vehicle is in a non-wading condition or the wading depth is relatively shallow, the cover plate 13 forms a seal with the second air inlet 12 under the action of gravity and the like, effectively suppressing the backflow of hot air. At this time, the air flows through the first air intake path, flows from the side of the guide plate 20 away from the front-end module 10 along the third direction C to the first air intake 23, and enters the air intake sealing cavity of the air intake extension channel structure 30, and then flows into the front-end module 10 from the connecting port 11, and finally enters the engine, which can ensure the normal operation requirements of the entire vehicle and the engine and improve the vehicle's power economy.

[0080] Optionally, in an environment with thin air, the cover plate 13 can be used as an actuator electronic controller switch, and both the first intake path and the second intake path can be opened to increase the amount of air entering the engine to meet the engine's intake demand.

[0081] According to some embodiments of the present invention, Figure 1 As shown, the air intake device 100 also includes: an air filter 41 and a guide pipe 40. The guide pipe 40 is arranged between the air filter 41 and the connecting port 11. The guide pipe 40 connects the connecting port 11 and the air filter 41, and is used to pass the air entering the connecting port 11 through the air filter 41 to the air intake of the engine. The air filter 41 is suitable for removing impurities such as dust and sand particles in the air. The air in the air intake sealing cavity of the air intake extension channel structure 30 flows out from the connecting port 11 and enters the guide pipe 40. The guide pipe 40 guides the air to the air filter 41, and the air filtered by the air filter 41 finally flows to the engine. In this way, clean air can be ensured to enter the engine, the normal operation of the engine can be ensured, the service life of the engine can be extended, and the reliability of the air intake device 100 can be improved.

[0082] According to some embodiments of the present invention, the air intake device 100 further includes: a second seal, which is disposed between the air intake extension channel structure 30 and the guide plate 20 and the front end module 10 .

[0083] The second seal is arranged between one end of the air intake extension channel structure 30 adjacent to the guide plate 20 and the guide plate 20, and between one end of the air intake extension channel structure 30 adjacent to the front end module 10 and the front end module 10, and the second seal is adapted to the shape and size of the air intake extension channel structure 30, and the second seal is suitable for connecting the air intake extension channel structure 30 with the guide plate 20 and the front end module 10 and achieving sealing.

[0084] Therefore, by setting a second seal between the air intake extension channel structure 30 and the guide plate 20 and the front end module 10, the sealing between the air intake extension channel structure 30 and the guide plate 20 and the front end module 10 can be improved, and the connection strength between the air intake extension channel structure 30 and the guide plate 20 and the front end module 10 can be improved, thereby improving the overall sealing and structural strength of the air intake device 100, improving the reliability of the air intake device 100, preventing hot air from flowing back, and avoiding engine knock. At the same time, it can avoid air loss during transmission and meet the engine's air intake volume.

[0085] Optionally, the second sealing member is a sponge strip, a sponge block, or a rubber strip, a rubber block.

[0086] In this embodiment, the main structure of the air extraction device 100 is made of plastic, thereby reducing the cost, reducing the weight of the air extraction device 100, achieving a lightweight design of the air extraction device 100, and improving the versatility of the air extraction device 100.

[0087] The engine assembly according to the second embodiment of the present invention comprises the air intake device 100 in the above embodiment.

[0088] According to the vehicle of the third aspect embodiment of the present invention, the vehicle includes: an engine, an air intake device 100 and a front bumper, the air intake device 100 is the air intake device 100 of any one of the above embodiments; the front bumper is provided with an air intake grille, the guide plate 20 of the air intake device 100 is opposite to the air intake grille, the guide plate 20 is arranged between the front bumper and the front end module 10 of the air intake device 100, the two ends of the guide plate 20 are respectively connected to the front bumper and the front end module 10, and the air entering the air intake grille enters the engine through the guide plate 20.

[0089] One end of the deflector 20 away from the front module 10 along the first direction A is opposite to the air intake grille, and a sealed connection is formed between the deflector 20 and the front bumper. When the vehicle is in a non-wading condition or the wading depth is shallow, the second air intake port 12 is closed, and the air entering the air intake grille flows through the first air intake path, flows from the side of the deflector 20 away from the front module 10 along the third direction C to the first air intake port 23, and enters the air intake sealing cavity of the air intake extension channel structure 30, and then flows into the front module 10 through the connecting port 11, and finally enters the engine.

[0090] When the vehicle's wading level exceeds the upper boundary of the air intake grille of the front bumper, air cannot enter the air intake extension channel structure 30 from the air intake grille. At this time, the cover plate 13 opens the second air intake port 12 under the action of the suction force of the engine. The air flows through the second air intake path, enters the air intake extension channel structure 30 from the second air intake port 12, and flows to the engine from the connecting port 11.

[0091] In this way, the engine's air intake needs in multiple scenarios can be met, the vehicle's adaptability can be improved, the vehicle's power economy under non-wading conditions can be improved, and at the same time, the vehicle's safety during deep wading can be improved.

[0092] According to some embodiments of the present invention, the air intake device 100 further includes: a radiator, which is disposed between the front bumper and the engine.

[0093] The radiator is arranged between the front bumper and the engine, and the radiator is arranged adjacent to the engine. The radiator is fixedly connected to the front end module 10. The radiator is suitable for cooling the cooling water of the engine. When wading deeply, the air on the side of the radiator away from the guide plate 20 along the first direction A flows through the second air intake path, enters the air intake extension channel structure 30 from the second air intake port 12, and flows to the engine from the connecting port 11, so that the engine can work normally.

[0094] Optionally, the guide plate 20 is sealed to the radiator. Thus, when the engine is in idle and low speed conditions, it is possible to prevent the high-temperature air on the side of the radiator away from the guide plate 20 along the first direction A from flowing back into the guide plate 20 from the gap between the guide plate 20 and the radiator, thereby preventing the engine from knocking, and at the same time, reducing the return temperature and improving the cooling performance of the radiator.
