Description

Technical Field

[0001] This utility model relates to the field of automotive air filter technology, and more specifically, to an air filter intake structure and a vehicle. Background Technology

[0002] The automotive intake system is primarily used to guide air or a mixture of air and fuel into the engine cylinders. In rainy weather or when driving through puddles, the water kicked up by the vehicle's high speed can enter the air filter through the intake manifold. In current technology, a large amount of water entering the air filter can wet the filter element and even cause water to enter the engine, leading to corrosion and other problems, which are detrimental to the engine's lifespan. Utility Model Content

[0003] In view of this, the present invention aims to provide an air filter intake structure and vehicle to solve at least one of the technical problems in the prior art, such as water entering the air filter and wetting the filter element, or even causing a shortening of engine life.

[0004] This utility model provides an air filter intake structure, including a first driving device, a first baffle, and an intake housing. The first baffle is rotatably connected to the intake housing. The intake housing includes a first housing, a second housing, and a first partition. The first housing and the first partition are connected to form an intake cavity. The first partition and the second housing are connected to form a first sub-cavity. The first sub-cavity is located on the lower side of the intake cavity. The first housing is provided with an air inlet. The first partition is provided with a liquid passage hole. The air outlet of the air inlet is oriented towards the liquid passage hole. The first driving device is driven to connect with the first baffle to drive the first baffle to block the liquid passage hole.

[0005] Furthermore, multiple liquid passage holes are spaced apart on the first partition plate to form a grid hole structure.

[0006] Furthermore, the intake housing also includes a channel structure that forms a first through hole. The channel structure is connected to the first partition and extends into the first compartment. The intake cavity communicates with the first compartment through the first through hole.

[0007] Furthermore, the cross-sectional area of ​​the first through hole is 78–970 mm². 2 .

[0008] Furthermore, the depth of the first through hole is 15–35 mm.

[0009] Furthermore, the volume of the first sub-cavity is 1 to 2.5 L.

[0010] Furthermore, the first partition includes a first plate segment and a second plate segment. The first plate segment is provided with the liquid passage hole. The first plate segment is set at a first preset angle with the orientation of the air inlet. The second plate segment is set at a second preset angle with the orientation of the air inlet. The first preset angle is greater than the second preset angle.

[0011] Furthermore, it also includes a water level sensor, which is disposed in the air intake cavity.

[0012] Furthermore, a drain hole is provided on the second housing.

[0013] This utility model also provides a vehicle including the aforementioned air filter intake structure.

[0014] The air filter intake structure of this utility model consists of an intake chamber formed by a first housing and a first partition, and a first sub-chamber formed by a second housing and the first partition. A first drive device drives a first baffle to rotate, thereby controlling the opening and closing of the liquid passage holes on the first partition. When the first baffle blocks the liquid passage holes, gas enters the intake chamber from the intake port but does not enter the first sub-chamber, and the air filter operates normally. When the first baffle rotates, connecting the intake chamber and the first sub-chamber through the liquid passage holes, a large amount of water enters the intake chamber. Inertia causes the water to continue moving into the first sub-chamber without contacting the air filter element through the intake chamber. This gives the air filter intake structure a certain degree of waterproofing, preventing the air filter element from being wetted by a large amount of water and avoiding water entering the engine and causing corrosion, thus ensuring the filtration effect of the air filter and extending the engine's service life. In addition, the first partition effectively divides the inner cavity of the air filter intake structure into the intake chamber and the first sub-chamber, resulting in a more compact overall structure that occupies less space, providing more space for other components on the vehicle.

[0015] The vehicle of this utility model has all the beneficial effects of the air filter intake structure described above, which will not be repeated here.

[0027] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but these are not intended to limit the scope of the present invention.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein.

[0029] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to the present invention.

[0030] Combination Figures 1 to 5 As shown in the figure, the Z-axis represents the vertical direction of the vehicle, where the positive direction of the Z-axis represents the top direction of the vehicle, and the negative direction of the Z-axis represents the bottom direction of the vehicle. Unless otherwise stated, the description of the relative positional relationship of the corresponding components on the vehicle in this utility model specification is only an exemplary description and does not limit the components to conform to the relative positional relationship.

[0031] This utility model provides an air filter intake structure, including a first driving device 1, a first baffle 2, and an intake housing 3. The first baffle 2 is rotatably connected to the intake housing 3. The intake housing 3 includes a first housing 31, a second housing 32, and a first partition 33. The first housing 31 and the first partition 33 are connected to form an intake cavity 10. The first partition 33 and the second housing 32 are connected to form a first sub-cavity 20. The first sub-cavity 20 is located on the lower side of the intake cavity 10. The first housing 31 is provided with an air inlet 311. The first partition 33 is provided with a liquid passage hole 3311. The air outlet end of the air inlet 311 is arranged facing the liquid passage hole 3311. The first driving device 1 is drivenly connected to the first baffle 2 to drive the first baffle to block the liquid passage hole 3311.

[0032] Combination Figures 1 to 3As shown, the first housing 31 of the air intake housing 3 is provided with an air inlet 311. The air inlet 311 can be any shape, such as a round hole or a square hole, so that air or a mixture can enter the air filter. The first drive device 1 can be a device that can provide power, such as a motor, a hydraulic valve, or a pneumatic valve, or a combination of several devices. The first baffle 2 is rotatably connected to the air intake housing 3 (it can be rotatably connected to the first housing 31, and / or the second housing 32, and / or the first partition 33, as long as it can rotate to block the liquid passage 3311). The power provided by the first drive device 1 can drive the first baffle 2 to rotate relative to the air intake housing 3.

[0033] In this embodiment, the air intake housing 3 is composed of a first housing 31, a second housing 32, and a first partition 33. The first housing 31, the second housing 32, and the first partition 33 can be connected and fixed by means of integral connection, welding, bolt connection, etc., and the appropriate connection method can be selected according to actual needs; no limitation is made here. The first housing 31 and the first partition 33 together form the air intake cavity 10, and the air outlet 311 (which can be determined according to...) Figure 2 , Figure 4 and Figure 5 The double-row arrows in the diagram indicate the airflow direction in this embodiment. Figure 2 For example, the air inlet 311 (with the air inlet end on the left and the air outlet end on the right) is connected to the air intake chamber 10, and air or a mixture of gases enters the air intake chamber 10 through the air inlet 311. The second housing 32 and the first partition 33 are connected to form the first sub-chamber 20, which is located on the lower side of the air intake chamber 10 (i.e., the side opposite to the Z-axis; this is not limited to the first sub-chamber 20 being located directly below the air intake chamber 10, for example...). Figure 2 As shown, the first chamber 20 can also be located at the lower right of the air intake chamber 10. A liquid passage hole 3311 is provided on the first partition plate 33, and the air outlet of the air inlet 311 is positioned facing the liquid passage hole 3311 (this does not limit the air outlet of the air inlet 311 to be directly opposite the liquid passage hole 3311; for example...). Figure 4 and Figure 5 As shown, the air outlet of the air inlet 311 faces to the left, and the position of the liquid passage 3311 corresponds to the air outlet of the air inlet 311. At the same time, the liquid passage 3311 is set at an angle.

[0034] Combine Figure 4 As shown, driven by the first driving device 1, when the first baffle 2 rotates to a certain angle, it can block the liquid passage 3311. At this time, the air filter or the vehicle is in a normal state or a non-water-immersed state. After the air filter intake structure of this utility model is combined with other components to form an air filter, the air or mixture entering the intake chamber 10 will be blocked by the first baffle 2 and then flow to the air filter element. After filtration, it enters the engine.

[0035] Combination Figure 5 As shown, driven by the first driving device 1, when the first baffle 2 rotates to another angle, the liquid passage 3311 opens, and the air intake chamber 10 and the first sub-chamber 20 are connected through the liquid passage 3311. At this time, the air filter or the vehicle is in a waterproof or wading state. A large amount of water enters the air intake chamber 10 through the air intake port 311. When the water enters the air intake chamber 10, it has a certain inertia and still moves towards the liquid passage 3311, and then enters the first sub-chamber 20 (at the same time, the engine suction will also form a negative pressure, causing the water to rush into the first sub-chamber 20 quickly). The first sub-chamber 20 is equivalent to a water storage chamber at this time, storing the water that enters the air filter intake structure. After the air filter intake structure of this utility model is combined with other components to form an air filter, it can prevent the water entering the air filter intake structure from passing through the filter element or entering the engine.

[0036] The air filter intake structure of this utility model comprises an intake cavity 10 formed by a first housing 31 and a first partition 33, and a first sub-cavity 20 formed by a second housing 32 and the first partition 33. A first drive device 1 drives a first baffle 2 to rotate, thereby controlling the opening and closing of the liquid passage hole 3311 on the first partition 33. When the first baffle 2 blocks the liquid passage hole 3311, gas enters the intake cavity 10 through the intake port 311 but not into the first sub-cavity 20, and the air filter operates normally. When the first baffle 2 rotates, causing the liquid passage hole 3311 to connect the intake cavity 10 and the first sub-cavity 20, the air filter can operate normally. When water enters the intake chamber 10, its inertia causes it to continue moving into the first sub-chamber 20 without contacting the air filter element. This gives the air filter intake structure a certain degree of water resistance, preventing the air filter element from being soaked by a large amount of water and avoiding water entering the engine and causing corrosion. This ensures the filtration effect of the air filter and helps extend the engine's service life. In addition, the first partition 33 effectively divides the inner cavity of the air filter intake structure into the intake chamber 10 and the first sub-chamber 20. The overall structure is relatively compact and occupies less space, providing more space for other components on the vehicle.

[0037] Optionally, combined Figure 4 and Figure 5 As shown, the second housing 32 has a drain hole 321.

[0038] For example, the drain hole 321 can guide the water in the first compartment 20 to the outside to be discharged, ensuring that the first compartment 20 will not be filled, which in turn is beneficial to the waterproof performance of the air filter intake structure.

[0039] Furthermore, a plurality of liquid passage holes 3311 are spaced apart on the first partition plate 33 to form a grid hole structure.

[0040] Combination Figure 4 and Figure 5 As shown in the figure, the air filter intake structure after being cut open is shown. The figure shows two liquid passage holes 3311 spaced apart on the first partition plate 33. In fact, there is another liquid passage hole 3311 in the cut-out part of the first partition plate 33. These three liquid passage holes 3311 constitute the grid hole structure. In practical applications, the size and number of the corresponding liquid passage holes 3311 can be selected as needed, which is not limited here.

[0041] Thus, the liquid passage holes 3311 of the grid hole structure increase the flow area, which can withstand a large amount of water passing through, better protect the filter element and the engine, and at the same time help improve the structural strength of the first partition 33.

[0042] Furthermore, the air intake housing 3 also includes a channel structure 34, which forms a first through hole 341. The channel structure 34 is connected to the first partition 33 and extends into the first sub-cavity 20. The air intake cavity 10 communicates with the first sub-cavity 20 through the first through hole 341.

[0043] Combination Figures 2 to 5 As shown, the channel structure 34 in this embodiment is cylindrical in shape, forming a circular first through hole 341. The channel structure 34 and the first partition 33 can be connected and fixed together by any means such as integral connection, welding, or bolt connection. The channel structure 34 extends into the first sub-cavity 20, so that the intake cavity 10 is connected to the first sub-cavity 20 through the first through hole 341. The first sub-cavity 20 is equivalent to a resonant cavity, which can suppress the noise in a certain frequency domain, thereby improving the noise of the intake system.

[0044] It should be noted that the main factors affecting resonance suppression include the volume of the resonant cavity (i.e., the first sub-cavity 20) and the first through hole 341, etc. The specific dimensions of the first sub-cavity 20 and the first through hole 341 can be designed as needed.

[0045] In a preferred embodiment, the cross-sectional area of ​​the first through hole 341 is 78–970 mm. 2 .

[0046] In this embodiment, the shape of the first through hole 341 is not limited. It can be a circular through hole, or other shapes, or it can be formed by combining multiple first through holes 341. There is no limitation here.

[0047] In a preferred embodiment, the depth of the first through hole 341 is 15-35 mm.

[0048] In this embodiment, the depth of the first through hole 341 is equivalent to Figures 1 to 5The length of the central channel structure 34. Thus, the depth range of the first through hole 341 enables the first cavity 20 to suppress resonance noise in the lower frequency domain.

[0049] In a preferred embodiment, the volume of the first compartment 20 is 1 to 2.5 L.

[0050] In this embodiment, the first cavity 20 is equivalent to a resonant cavity, and the volume of the resonant cavity is 1 to 2.5L. The specific shape of the first cavity 20 is not limited here and can be designed as needed.

[0051] More preferably, the cross-sectional area of ​​the first through hole 341 is 78–970 mm. 2 The depth of the first through hole 341 is 15-35 mm, and the volume of the first cavity 20 is 1-2.5 L.

[0052] Based on the cross-sectional area of ​​the first through hole 341, the depth of the first through hole 341, and the volume of the first cavity 20, it can be determined that the first cavity 20 in this embodiment is a resonant cavity, which can suppress low-frequency noise (50-500 Hz) and effectively improve the low-frequency noise of the intake system.

[0053] Furthermore, the first partition 33 includes a first plate segment 331 and a second plate segment 332. The first plate segment 331 is provided with the liquid passage hole 3311. The orientation of the first plate segment 331 and the air inlet 311 is set at a first preset angle. The orientation of the second plate segment 332 and the air inlet 311 is set at a second preset angle. The first preset angle is greater than the second preset angle.

[0054] Combination Figure 4 and Figure 5 As shown, the first partition 33 is integrally connected to a first plate segment 331 and a second plate segment 332 (it can also be connected by welding, bolting, etc., as long as the first plate segment 331 and the second plate segment 332 are connected). A liquid passage hole 3311 is provided on the first plate segment 331, and a channel structure 34 is provided on the second plate segment 332. Figure 2 and Figure 3As shown, the second plate segment 332 is positioned opposite the first chamber 20 (i.e., the positive Z-axis side in this embodiment) and faces the air filter element 100. The first plate segment 331 and the air inlet 311 are positioned at a first preset angle θ (two dashed lines in the figure represent the straight line parallel to the first plate segment 331 and the central axis of the air inlet 311, respectively). The first preset angle θ is preferably set to 30 to 70°. This angle allows the gas to flow upward under the guidance of the first plate segment 331, which is beneficial for the gas to move towards the air filter element 100. Once the first baffle 2 opens the liquid passage hole 3311, water will pass through the liquid passage hole 3311 and enter the first chamber 20 through the first plate segment 331.

[0055] The second plate segment 332 is set at a second preset angle δ with respect to the air inlet 311 (the figure shows two dashed lines representing a straight line parallel to the second plate segment 333 and a straight line parallel to the central axis of the air inlet 311, respectively). The second preset angle δ is preferably set to 2 to 20°. This angle allows the gas to flow upward under the guidance of the second plate segment 332, which is beneficial for the gas to move towards the air filter element 100. It can also expand the volume of the first compartment 20 to a certain extent and increase the water storage capacity. When the second plate segment 332 is provided with a channel structure 34, the second preset angle δ is beneficial for its first through hole 341 to be set towards the air filter element 100, which is beneficial for suppressing noise.

[0056] Thus, by setting the first plate segment 331 and the air inlet 311 at a first preset angle, and setting the second plate segment 332 and the air inlet 311 at a second preset angle, the gas can be guided to move towards the air filter element 100 after entering the air filter intake structure, ensuring that the gas can flow normally to the filter element and enter the engine.

[0057] Preferably, it also includes a water level sensor, which is disposed in the air intake cavity 10 (the water level sensor is not shown in the figure).

[0058] For example, the water level sensor can detect the water content in the air intake chamber 10. If the detected water content is greater than the preset threshold, it can be determined that the air filter or the vehicle is in a water-wading state. The water level sensor can be connected to the vehicle computer to prompt the occupants that the vehicle is in a water-wading state. It can also automatically control the first drive device 1 or prompt the occupants to manually control the first drive device 1 to drive the first baffle 2 to rotate, thereby opening the liquid passage hole 3311. This timely and intelligently protects the air filter element 100 from getting wet, avoids water entering the engine and causing rust and other problems, and helps to extend the engine's service life.

[0059] This utility model also provides an air filter, including an air filter element 100, an air filter outlet structure 200, and an air filter inlet structure. The air filter outlet structure 200 is connected to a first housing 31. The air filter outlet structure 200 is provided with an outlet cavity 210. The air filter element 100 is disposed between the inlet cavity 10 and the outlet cavity 210.

[0060] Combination Figure 1 and Figure 2 As shown, the air filter element 100 is disposed between the exhaust chamber 210 and the intake chamber 10. When the first drive device 1 drives the first baffle 2 to rotate to block the liquid passage 3311, the vehicle is in a non-wading state. Gas enters the intake chamber 10 from the intake port 311, and after being filtered by the air filter element 100, it enters the engine through the exhaust chamber 210. When the first drive device 1 drives the first baffle 2 to rotate to open the liquid passage 3311, the vehicle is in a wading state. Water enters the intake chamber 10 from the intake port 311 and, due to inertia, passes through the liquid passage 3311 into the first compartment 20. The first compartment 20 is equivalent to a water storage chamber, ensuring that water does not come into contact with the air filter element 100 through the intake chamber 10. The second housing 32 of the intake housing 3 may optionally be provided with a drain hole 321 to allow water to drain out from the drain hole 321.

[0061] The air filter of this invention adopts the aforementioned air filter intake structure. An intake chamber 10 is formed by a first housing 31 and a first partition 33, and a first sub-chamber 20 is formed by a second housing 32 and the first partition 33. A first driving device 1 drives a first baffle 2 to rotate, thereby controlling the opening and closing of the liquid passage hole 3311 on the first partition 33. When the first baffle 2 blocks the liquid passage hole 3311, gas enters the intake chamber 10 through the intake port 311 but does not enter the first sub-chamber 20, and the air filter operates normally. When the first baffle 2 rotates, the liquid passage hole 3311 connects the intake chamber 10 and the first sub-chamber 20. When the engine starts, a large amount of water enters the intake chamber 10. Inertia causes the water to continue moving into the first sub-chamber 20 without coming into contact with the air filter element through the intake chamber 10. This gives the air filter intake structure a certain degree of waterproofing, preventing the air filter element from being wetted by a large amount of water and preventing water from entering the engine and causing problems such as rust. This ensures the filtering effect of the air filter and helps extend the service life of the engine. In addition, the first partition 33 effectively divides the inner cavity of the air filter intake structure into the intake chamber 10 and the first sub-chamber 20. The overall structure is relatively compact and occupies less space, providing more space for other components on the vehicle.

[0062] This utility model also provides a vehicle including the aforementioned air filter intake structure.

[0063] The vehicle of this invention employs the aforementioned air filter intake structure in its air filter system. Air or a mixture of air and gas can enter the engine through the air filter. The air filter intake structure forms an intake chamber 10 via a first housing 31 and a first partition 33, and a first sub-chamber 20 via a second housing 32 and the first partition 33. A first drive device 1 drives a first baffle 2 to rotate, thereby controlling the opening and closing of the liquid passage 3311 on the first partition 33. When the first baffle 2 blocks the liquid passage 3311, gas enters the intake chamber 10 from the intake port 311 and does not enter the first sub-chamber 20, allowing the air filter to operate normally. When the first baffle 2 rotates, the liquid passage 3311 is blocked. When the intake chamber 10 and the first sub-chamber 20 are connected, a large amount of water enters the intake chamber 10. Inertia causes the water to continue moving into the first sub-chamber 20 without contacting the air filter element through the intake chamber 10. This gives the air filter intake structure a certain degree of waterproofing, preventing the air filter element from being wetted by a large amount of water and preventing water from entering the engine and causing rust and other problems. This ensures the filtration effect of the air filter and helps extend the service life of the engine. In addition, the first partition 33 effectively divides the inner cavity of the air filter intake structure into the intake chamber 10 and the first sub-chamber 20. The overall structure is relatively compact and occupies less space, providing more space for other parts of the vehicle.
