[0036] In order to solve the technical problems existing in the related art, the present application provides a vehicle air intake device, see Figure 1-Figure 7 , Figure 1 This is a schematic diagram of the structure of the vehicle air intake device provided by this application.

Figure 7 yes Figure 1The second perspective structural schematic diagram of the vehicle air intake device is shown.
[0037] The vehicle air intake device 1 includes an air duct body 10 and a control valve 40. The air duct body 10 is formed with a first air flow channel 20 and a second air flow channel 30. The first air flow channel 20 has a first air inlet 210 and a second air inlet 220 arranged coaxially. The second air flow channel 30 has an air outlet 310. The air outlet 310 is located between the first air inlet 210 and the second air inlet 220. The second air flow channel 30 is connected to the first air flow channel 20 through the air outlet 310; the control valve 40 is connected to the air duct body 10, and the control valve 40 is configured to open or close the first air inlet 210 and the air outlet 310, wherein the intake temperature of the first air inlet 210 is lower than the intake temperature of the second air inlet 220, and the intake rate of the first air inlet 210 is greater than the intake rate of the second air inlet 220.
[0038] By setting the first air inlet 210 and the second air inlet 220, the vehicle air intake device 1 can be used to introduce suitable gas from the outside in different ways. When in a high-temperature environment, the control valve 40 connects the first air inlet 210 and the air outlet 310. At this time, the vehicle air intake device 1 is in the first state. The gas enters the first air flow channel 20 from the first air inlet 210 and enters the second air flow channel 30 through the air outlet 310. Because the air intake rate of the first air inlet 210 is greater than that of the second air inlet 220, the gas entering from the first air inlet 210 will flow to the second air inlet 220, and can hinder the gas entering from the second air inlet 220 from flowing into the first air flow channel to a certain extent. 20 and the second air flow channel 30, thereby reducing the temperature of the gas entering the second air flow channel 30; when in a low temperature environment, the control valve 40 cuts off the first air inlet 210 and the air outlet 310. At this time, the vehicle air intake device 1 is in the second state, and the gas can only enter the first air flow channel 20 from the second air inlet 220 and enter the second air flow channel 30 through the air outlet 310, thereby increasing the temperature of the gas entering the second air flow channel 30, so that the gas entering the second air flow channel 30 in different environments can be more suitable. It should be noted that the control valve 40 can also be set to multiple, so that the control valve 40 can simultaneously control the conduction or cutoff between the second air inlet 220 and the air outlet 310.
[0039] It should be noted that the first air inlet 210 is positioned toward the windward side, while the second air inlet 220 is positioned oppositely toward the leeward side. Therefore, the air intake rate of the first air inlet 210 is greater than that of the second air inlet 220, and the air intake temperature of the first air inlet 210 is lower than that of the second air inlet 220. The second air flow channel 30 is connected to the interior of the engine, supplying gas to the engine. An air filter is also provided on the second air flow channel 30 to prevent impurities from entering the engine. The first and second air inlets 210, 220 draw gas from the outside into the first air flow channel 20, where it then enters the second air flow channel 30 through the air outlet 310. The coaxial arrangement of the first and second air inlets 210, 220 ensures that most impurities in the gas entering the first air flow channel 20 flow toward the first or second air inlet 210, 220, reducing the probability of impurities entering the air outlet 310.
[0040] The control valve 40 includes a blocking portion 420 and a control portion 410. The blocking portion 420 is arranged inside the first air flow channel 20, and the control portion 410 is arranged outside the first air flow channel 20. The control portion 410 is used to control the angle between the blocking portion 420 and the first air inlet 210 so as to connect or cut off the first air inlet 210 and the air outlet 310.
[0041] The control valve 40 is positioned near the first air inlet 210, and the blocking portion 420 is capable of completely blocking the cross-section of the first air flow channel 20 near the first air inlet 210. This completely blocks the air intake cross-section of the first air inlet 210, preventing external air from entering the first air flow channel 20 through the first air inlet 210. This blocks the air flow path between the first air inlet 210 and the air outlet 310. By adjusting the angle between the blocking portion 420 and the first air inlet 210, the air intake cross-section of the first air inlet 210 can be adjusted, thereby adjusting the air intake rate of the first air inlet 210.
[0042] The control valve 40 can intelligently control the angle between the blocking part 420 and the first air inlet 210 by detecting the temperature or parameter feedback such as the oxygen content inside the engine through the vehicle ambient temperature sensor, intake manifold temperature and pressure sensor, engine knock sensor, catalyst front and rear oxygen sensors, etc. inside the vehicle. For example, when the temperature is detected to be too low, the control valve 40 controls the blocking part 420 to completely close the air intake cross-section of the first air inlet 210. When knock or insufficient oxygen content is detected, the control valve 40 controls the blocking part 420 to adjust the air intake cross-section of the first air inlet 210, so that external gas enters the first air flow channel 20 from the first air inlet 210. The control valve 40 can specifically be a solenoid valve.
[0043] The blocking portion 420 has a blocking surface. When the blocking portion 420 blocks the first air inlet 210 and the air outlet 310, the blocking surface is perpendicular to the axial direction of the first air flow channel 20. When the blocking portion 420 connects the first air inlet 210 and the air outlet 310, the blocking surface is non-perpendicular to the axial direction of the first air flow channel 20.
[0044] The blocking surface of the blocking portion 420 is adapted to the channel cross-section of the first air flow channel 20. When the blocking surface is perpendicular to the axial direction of the first air flow channel 20, the vehicle air intake device 1 is in the second state, that is, the angle between the blocking portion 420 and the first air inlet 210 is zero degrees. The blocking portion 420 completely closes the channel cross-section of the first air flow channel 20 close to the first air inlet 210, that is, the air intake cross-section of the first air inlet 210 is closed, and the external air near the first air inlet 210 is blocked outside the first air flow channel 20 by the blocking portion 420, so that the first air inlet 210 and the outlet are completely closed. The airflow path between the air inlets 310 is blocked; when the axial angle between the blocking surface and the first air flow channel 20 is less than 90 degrees (non-perpendicular), the vehicle air intake device 1 is in the first state, that is, the angle between the blocking portion 420 and the first air inlet 210 is less than 90 degrees, and the channel cross-section of the first air flow channel 20 near the first air inlet 210 can be at least partially exposed, so that external air near the first air inlet 210 adjacent to the blocking portion 420 can enter the first air flow channel 20, thereby connecting the air flow path between the first air inlet 210 and the air outlet 310. When the axial angle between the blocking surface and the first air flow channel 20 is less than 90 degrees, the intake rate of air entering the first air flow channel 20 through the first air inlet 210 can be controlled by adjusting the angle. When the axial angle between the blocking surface of the blocking portion 420 and the first air flow channel 20 is zero degrees, the intake rate of the first air inlet 210 reaches the maximum.
[0045] The control valve 40 further includes a rotating shaft portion 430, which passes through the air duct body 10 and extends to the first air flow channel 20 and is fixedly connected to the blocking portion 420. The control unit 410 drives the blocking portion 420 to rotate via the rotating shaft portion 430. The control unit 410 controls the rotation of the rotating shaft portion 430, thereby changing the angle between the blocking portion 420 and the first air inlet 210. When the angle is greater than 0 degrees, the vehicle air intake device 1 is in a first state, in which the axial directions of the blocking portion 420 and the first air flow channel 20 are non-perpendicular, allowing external air to enter the first air flow channel 20 through the first air inlet 210. When the angle is 0 degrees, the vehicle air intake device 1 is in a second state, in which the axial directions of the blocking portion 420 and the first air flow channel 20 are perpendicular, preventing external air from entering the first air flow channel 20 through the first air inlet 210.
[0046] The air outlet 310 is centrally arranged relative to the first air inlet 210 and the second air inlet 220, so that the second air flow channel 30 and the air outlet 310 are located in the middle area of the first air flow channel 20. The air outlet 310 is neither too close to the first air inlet 210 nor too close to the second air inlet 220, thereby preventing the gas from the first air inlet 210 or the second air inlet 220 from directly entering the second air flow channel 30 through the air outlet 310, increasing the probability of impurities entering the second air flow channel 30, thereby affecting the air intake effect.
[0047] The inner diameter of the first airflow channel 20 ranges from 50 mm to 60 mm. The inner diameter of the first airflow channel 20 cannot be too small, otherwise it will affect the air intake effect of the vehicle air intake device 1. The inner diameter of the first airflow channel 20 cannot be too large, otherwise it will occupy too much space and affect the layout of other components. The channel cross-section of the first airflow channel 20 can be circular, square, rectangular, etc. In some embodiments, the channel cross-section of the first airflow channel 20 is rectangular. The length dimension of the rectangular channel cross-section can be 115 mm, and the width dimension can preferably be 55 mm. The wall thickness of the first airflow channel 20 can be 2.5 mm. The channel cross-section shape and size of the first airflow channel 20 can be adjusted according to actual conditions.
[0048] The inner diameter of the second airflow channel 30 ranges from 45 mm to 55 mm. The second airflow channel 30 is connected to the side of the first airflow channel 20 via the air outlet 310. Air entering the first airflow channel 20 flows between the first air inlet 210 and the second air inlet 220. Therefore, the inner diameter of the second airflow channel 30 cannot be too small, otherwise it will affect the air intake effect of the second airflow channel 30. Of course, due to the space constraints within the vehicle, the inner diameter of the second airflow channel 30 cannot be too large. Preferably, the inner diameter of the second airflow channel 30 is 50 mm, but this size can be adjusted according to actual conditions. The cross-sectional shape of the second airflow channel 30 can be circular, square, or other shapes, and can be adjusted according to actual conditions.
[0049] The vehicle air intake device 1 also includes a mounting bracket 50, which is positioned on the outer wall of the air duct body 10 and connected to the outer walls on both sides of the first air flow channel 20. There may be two mounting brackets 50: one is located on the side where the second air flow channel 30 connects to the first air flow channel 20, near the second air inlet 220; the other is located on the side of the first air flow channel 20 facing away from the second air flow channel 30, near the first air inlet 210. The mounting brackets 50 are provided with mounting holes, which allow bolts to be used to secure the vehicle air intake device 1. The inner diameter of the mounting holes can be set to 8.5 mm. The two mounting holes are spaced 180 mm apart in the direction from the second air flow channel 30 toward the first air flow channel 20, and 95 mm apart in the direction from the first air inlet 210 toward the second air inlet 220. The position of the mounting brackets 50 and the size and spacing of the mounting holes can be adjusted according to actual needs.
[0050] In summary, the vehicle air intake device 1 of the present application introduces gas into the first air flow channel 20 from the outside through the first air inlet 210 and the second air inlet 220, and then sends the gas into the engine through the air outlet 310 of the second air flow channel 30. The control valve 40 controls the conduction or cutoff of the flow path between the first air inlet 210 and the air outlet 310, so that the vehicle air intake device 1 adopts different air inlets and air intake methods to introduce suitable gas in different environments. The unique setting between the first air inlet 210, the second air inlet 220 and the air outlet 310 also makes it difficult for impurities to enter the engine, so that the engine and the vehicle can perform excellent performance in different environments.
[0051] See also Figure 8 , Figure 8 It is a schematic diagram of the vehicle structure having the vehicle air intake device provided by the present application.
[0052] In order to solve the relevant technical problems, the present application also provides a vehicle, which includes a vehicle body 2 and any one of the above-mentioned vehicle air intake devices 1. The vehicle air intake device 1 is installed on the vehicle body 2. The vehicle using the vehicle air intake device 1 of the present application can exhibit excellent performance in different environments.
[0053] Vehicle body 2 includes a front grille 21. A first air inlet 210 of vehicle air intake device 1 is positioned toward front grille 21. Front grille 21 is located at the front of the vehicle, and most airflow is directed toward the front of the vehicle during driving. Therefore, positioning first air inlet 210 toward front grille 21 ensures that first air inlet 210 faces the windward direction, allowing air to flow through front grille 21 and toward first air inlet 210. Vehicle air intake device 1 is placed within the engine compartment at the front of the vehicle, above the radiator and away from heat sources such as the catalyst. In high-temperature environments, external air can be introduced through first air inlet 210. In low-temperature environments, external air cannot enter through first air inlet 210. Because heat sources such as the catalyst are present in the engine compartment, the air temperature inside the engine compartment is higher than the outside air temperature. Second air inlet 220 introduces air from the engine compartment, thereby improving engine performance.
