[0014] Optionally, the baffle assembly further includes a third baffle, which is connected to the first plate portion and extends toward the first baffle. The third baffle is connected to the first baffle via a connecting post.

[0015] This application also provides an engine intake system, the engine intake system including an intake passage portion, wherein the intake passage portion is provided with an intake turbulence structure as described above to form a first flow channel and a second flow channel within the intake passage portion, the extending directions of the first flow channel and the second flow channel having an angle.

[0043] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] The ordinal numbers used in this article, such as first and second, are used to distinguish different parts with the same name and do not indicate a specific order or primary / secondary relationship.

[0045] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the assembly structure of the front combination lamp frame 10 and the air intake grille 50 of the vehicle in this embodiment of the application. Figure 2 for Figure 1 A sectional view along the AA direction.

[0046] The vehicle is equipped with an engine intake system for supplying gas to the engine. The engine intake system includes an intake passage section. In this embodiment, the intake passage section specifically includes an intake grille 50, a first air guide 40, a second air guide 60, and a front combination lamp frame 10. The first air guide 40 is located above the second air guide 60, and the intake grille 50 is located below the second air guide 60. The intake grille 50, the first air guide 40, and the second air guide 60 are all located in front of the front combination lamp frame 10. The intake grille 50, the first air guide 40, the second air guide 60, and the front combination lamp frame 10 enclose and define the passage of the intake passage section. It should be noted that this is merely an illustrative example, and the structural form of the intake passage section is not limited to this. Figure 2 In the intake passage section, the passage includes a first passage section 100a extending generally vertically and a second passage section 100b extending generally horizontally. The first passage section 100a and the second passage section 100b are connected, and the second passage section 100b is located behind the first passage section 100a. Figure 2 The direction of air flow is indicated by dashed arrows. External air flows from front to back into the intake passage, then upwards, then from the first air guide shroud 40, and finally backwards, ultimately flowing towards the engine. In this embodiment, "up," "down," "front," and "rear" refer to... Figure 2 From a perspective, "front" and "rear" refer to the front and rear of the vehicle, and the vertical direction is also vertical.

[0047] It is worth noting that this embodiment provides an intake spoiler structure 30, which is disposed within the channel of the intake passage. Figure 2 As can be seen, the air intake turbulence structure 30 is specifically located inside the first air guide shroud 40, that is, at the junction of the first channel section 100a and the second channel section 100b.

[0048] Can continue to combine Figures 3 to 5 understand, Figure 3 for Figure 1 A schematic diagram of the front and middle combination lamp frame 10 with an air intake spoiler structure 30; Figure 4 for Figure 3 A three-dimensional structural diagram of the central air intake spoiler structure 30; Figure 5 A cross-sectional view showing the mating position of the air intake turbulence structure 30 and the first air guide shroud 40.

[0049] The intake spoiler structure 30 in this embodiment includes a baffle assembly, which includes a first baffle 302 and a second baffle 304. The first baffle 302 and the second baffle 304 are spaced apart and connected. Exemplarily, the intake spoiler structure 30 also includes a connecting post 308. Figure 4 In the middle, one end of the first baffle 302 and one end of the second baffle 304 are connected by a connecting post 308, and the other end of the first baffle 302 and the other end of the second baffle 304 are connected by another connecting post 308. With the vehicle as a reference, the two connecting posts 308 are distributed on the left and right sides. "Left" and "right" can be used as a reference. Figure 1 Illustration. Of course, the connection structure of the first baffle 302 and the second baffle 304 is not limited to this. For example, the middle of the first baffle 302 and the second baffle 304 can be connected by a connecting post. The connection method at both ends in this embodiment is more conducive to ensuring smooth gas flow.

[0050] After the intake turbulence structure 30 is installed in the intake passage, a first flow channel OB and a second flow channel OC for gas flow are formed. The extension directions of the first flow channel OB and the second flow channel OC have an angle between them.

[0051] Specifically, in this embodiment, the second baffle 304 includes a first plate portion 3041 and a second plate portion 3042 that are connected to each other. The first plate portion 3041 and the second plate portion 3042 have an included angle, that is, the second baffle 304 is not a flat plate as a whole, but can be... Figure 5 The bent plate shown can have a first plate portion 3041 and a second plate portion 3042 that are both straight plates, or at least one of the first plate portion 3041 and the second plate portion 3042 can be an arc-shaped plate, for example, the first baffle 302 can be an entirely arc-shaped plate. The first plate portion 3041 and the second baffle 304 can be arranged opposite to each other along the thickness direction of the baffle, and they can be parallel to each other or inclined relative to each other. In this case, the first plate portion 3041 and the second baffle 304 are used to define at least a portion of the wall of the first flow channel OB, such as... Figure 5 As shown, the first plate portion 3041 and the first baffle 302 together with the wall portion of the air intake passage portion form the first flow channel 0B. Specifically, the first flow channel 0B is formed together with the front combination lamp frame 10 and the first air guide shroud 40. That is, the first plate portion 3041 and the first baffle 302 are used to define part of the wall portion of the first flow channel 0B, and the first air guide shroud 40 and the front combination lamp frame 10 will serve as the other part of the wall portion of the first flow channel 0B. Of course, if the first plate portion 3041 and the first baffle 302 enclose an annular cavity, the first flow channel 0B can be directly defined. In this case, at least one of the first plate portion 3041 and the first baffle 302 can be a cylindrical plate structure.

[0052] The second baffle 304 also includes a second plate portion 3042, which defines at least a portion of the wall of the second flow channel OC. The second plate portion 3042 and the wall of the intake passage portion together enclose and form the second flow channel OC. Figure 5 In this embodiment, the second plate portion 3042 and the first air guide shroud 40 enclose and define the second flow channel OC. Obviously, if the second plate portion 3042 is set as a cylindrical plate structure, the second flow channel OC can be directly defined. In this embodiment, the first plate portion 3041 and the second plate portion 3042 of the first baffle 302 and the second baffle 304 are both flat plate structures. The first flow channel OB and the second flow channel OC are defined by the wall of the original air intake channel, which saves more material and the air intake turbulence structure 30 is easier to process and manufacture.

[0053] With this configuration, when gas enters the intake passage and passes through the intake spoiler structure 30, it must first pass through the first flow channel OB, then flow into the second flow channel OC, and finally flow into the engine's intake pipe 20. This increases the number of changes in the gas flow direction, essentially creating a labyrinth structure within the intake passage. If the gas contains rain, snow, or other contaminants, these will be blocked by the intake spoiler structure 30. Especially in rainy or snowy weather, this effectively reduces the amount of rain and snow entering the engine's intake pipe 20. For example, tests in snowy weather show that, compared to the solutions in the prior art, this embodiment, with the intake spoiler structure 30 in the intake passage, can block at least 60% of snowflakes, ensuring sufficient air enters the engine for combustion and guaranteeing normal engine operation.

[0054] Furthermore, the vehicle in this embodiment can be a range-extended electric vehicle (REEV). A REEV is essentially a pure electric vehicle; its driving power is entirely provided by the drive motor. The engine does not directly participate in driving the vehicle but plays a role in generating electricity. When the battery's charge is insufficient, the engine starts, converting fuel into electrical energy to power the drive motor or charge the battery. Therefore, the design of a REEV retains the design characteristics of an electric vehicle, such as... Figure 1 As shown, the air intake grille 50 is located at the lower part of the front side of the vehicle, forming an air intake channel for air intake from below. This makes it easier for rain, snow, and other objects to enter the engine intake system. Therefore, the air intake spoiler structure 30 in this embodiment effectively improves the problem of rain, snow, and other objects entering the engine intake system when applied to range-extended electric vehicles.

[0055] In this embodiment, the intake spoiler structure 30 can be located before the air filter of the engine intake system, which also helps to protect the air filter.

[0056] like Figure 4 , 5As shown, the baffle assembly in this embodiment further includes a third baffle 311, which is connected to the first plate portion 3041, specifically at the junction of the first plate portion 3041 and the second plate portion 3042. The second baffle 304 and the third baffle 311 combine to form a Y-shaped structure. The third baffle 311 extends toward the first baffle 302 and is connected to the first baffle 302 via a connecting post 308, meaning the second baffle 304 is indirectly connected to the first baffle 302. At this time, gas passes between the two connecting posts 308 to enter the second flow channel 0C. The third baffle 311 further ensures that rain, snow, etc., cannot enter the second flow channel 0C.

[0057] like Figure 2 As shown, the intake passage generally includes a first passage section 100a extending vertically and a second passage section 100b extending horizontally. The intake spoiler structure 30 is located at the junction of the first passage section 100a and the second passage section 100b, which in this embodiment is approximately located inside the first air guide shroud 40. At this location, the gas is about to flow backward into the engine's intake pipe 20. By placing the intake spoiler structure 30 at this location, it can better block the entry of objects such as rain and snow. It can be understood that the intake spoiler structure 30 can also be placed at other locations in the intake passage.

[0058] like Figure 5 As shown, in this embodiment, the first baffle 302 seals a portion of the first channel section 100a and forms a first air inlet OA on the side near the second channel section 100b. Specifically, a portion of the edge of the first baffle 302 abuts against the inner wall of the air inlet channel, that is, it abuts against the inner wall of the first air guide shroud 40. Another portion of the edge of the first baffle 302 has a gap with the inner wall of the air inlet channel, that is, it has a gap with the inner wall of the first air guide shroud 40 and the front combination lamp frame 10. This forms a first air inlet OA that connects to the first flow channel OB. The first air inlet OA is located inside the air inlet channel on the side near the second channel section 100b. Figure 5 In this configuration, the second channel section 100b is located behind the first channel section 100a, and the first air inlet OA is positioned slightly rearward within the first channel section 100a. Correspondingly, the second baffle 304 seals off a portion of the second channel section 100b, forming a second air inlet OA on the side furthest from the second channel section 100b. Figure 5 In the middle, the top of the second plate 3042 and the second channel section 100b are spaced to form a second air inlet 0D. With this arrangement, the gas from the upstream of the air intake turbulence structure 30, through the first air inlet 0A, needs to change direction to flow into the first flow channel 0B, then change direction to flow into the second flow channel 0C, and then continue to change direction to flow backward, thereby achieving the purpose of multiple changes of direction to block rain, snow and other objects.

[0059] In some embodiments, the first baffle 302 and the first plate portion 3041 may be inclined relative to the extending direction of the first channel segment 100a. For example... Figure 5 As shown, the first channel segment 100a extends vertically, and the first baffle 302 and the first plate portion 3041 are relatively vertically inclined. Therefore, the first flow channel 0B is also roughly vertically inclined. The second plate portion 3042 extends roughly vertically, and the second flow channel 0C also extends roughly vertically. After the gas flows vertically to the first air inlet 0A and enters the first flow channel 0B, its direction will tilt. Figure 5 The gas flows upwards and forwards at an angle, then continues to flow along the vertical second flow channel 0C. It is worth noting that the first baffle 302 is angled, allowing the surface area of ​​the gas-facing side to be relatively large, thus better blocking rain, snow, and other pollutants.

[0060] In this embodiment, the first baffle 302 and the first plate portion 3041 can be arranged in parallel, that is, they are approximately parallel, to form an inclined first flow channel OB. It is understood that the first baffle 302 is not limited to being relatively vertically inclined; for example, it can be directly arranged horizontally, while the first plate portion 3041 is inclined. More specifically, the first baffle 302 can be an arc-shaped plate, with the surface on the flow-facing side being arc-shaped and the flow-facing surface concave from bottom to top. This provides better obstruction of rain and snow, and also provides better guidance for the gas, allowing the gas to flow more smoothly towards the first air inlet OB.

[0061] For example, at least a portion of the edge of the first baffle 302 may be provided with a sealing structure 309, such as sealing cotton, which can be fixed to the edge of the first baffle 302 by means of adhesive bonding. The sealing structure 309 is used to seal against the inner wall of the intake passage of the engine intake system to ensure that as much gas as possible enters the first flow channel OB from the first intake port OA.

[0062] You can continue to refer to this. Figure 4The baffle assembly in this embodiment also includes a first plug-in plate 303 and a second plug-in plate 305 disposed opposite to each other. One end of the second baffle 304 is connected to the first plug-in plate 303, and the other end is connected to the second plug-in plate 305. The first plug-in plate 303 and the second plug-in plate 305 are both located on the side of the second baffle 304 away from the first baffle 302. Specifically, the first baffle 302 is located on the front side of the second baffle 304, and the first plug-in plate 303 and the second plug-in plate 305 are located on the rear side of the second baffle 304. With the vehicle as a reference, the first plug-in plate 303 and the second plug-in plate 305 are distributed left and right, and the first plug-in plate 303 and the second plug-in plate 305 also extend in a direction away from the first baffle 302, that is, extend rearward. The first plug-in plate 303 and the second plug-in plate 305 are used to insert into the slots (not shown in the figure) of the engine intake system, and the slots are specifically disposed on the front combination lamp frame 10. By inserting the first plug-in plate 303 and the second plug-in plate 305 into the slot, the intake turbulence structure 30 can be limited, which is beneficial to its positional stability. After insertion, it also helps to ensure the sealing of the second flow channel 0C. The two plug-in plates can be inserted from top to bottom, which is convenient for assembly.

[0063] Figure 4 In the middle, the first plug plate 303 and the second plug plate 305 are provided with anti-detachment protrusions 3031 on the opposite side of each other. The anti-detachment protrusions 3031 and the wall of the slot can abut and cooperate to prevent the first plug plate 303 and the second plug plate 305 from detaching from the slot, thereby further stabilizing the position of the air intake turbulence structure 30.

[0064] Let's look again. Figure 4 In this embodiment, the air intake spoiler structure 30 further includes a connecting beam 301. One end of the connecting beam 301 is connected to the first plug-in plate 303, and the other end is connected to the second plug-in plate 305, which can enhance the structural strength of the air intake spoiler structure 30. The air intake spoiler structure 30 may also include a connecting support 306 for connecting to the first air guide shroud 40. The connecting support 306 is connected to the connecting beam 301 and is provided with a first fastening hole 306a.

[0065] You can continue to refer to this. Figure 5 and combined Figure 6 understand, Figure 6 for Figure 4 A schematic diagram of the connection between the central air intake turbulence structure 30 and the first air guide shroud 40.

[0066] The first fastening hole 306a of the connecting support 306 in the intake spoiler structure 30 is used to connect with the first air guide shroud 40 of the engine intake system. The first air guide shroud 40 has a top cover plate 401, and the top cover plate 401 of the first air guide shroud 40 is provided with a second fastening hole, so that bolts 310 can be used to fix it through the first fastening hole 306a and the second fastening hole. In this way, the intake spoiler structure 30 and the first air guide shroud 40 can be fixedly connected more reliably. It can be seen that the connection method between the connecting support 306 and the first air guide shroud 40 is not limited to bolt connection, such as snap-fit, riveting, etc., and this embodiment does not make specific limitations. The connecting support 306 can be located in the middle of the connecting beam 301 to distribute the force evenly.

[0067] Let's look again. Figure 4 , 6 In this embodiment, the air intake spoiler structure 30 also includes reinforcing ribs 307. The reinforcing ribs 307 connect the second baffle 304 and the connecting beam 301, specifically connecting the first plate portion 3041 and the connecting beam 301. The connecting beam 301 is located above the first plate portion 3041 and can enhance the structural strength of the air intake spoiler structure 30. In this embodiment, the air intake spoiler structure 30 can be equipped with multiple reinforcing ribs 307. The reinforcing ribs 307 are obliquely arranged between the second baffle 304 and the connecting beam 301 to act as diagonal bracing, better ensuring strength. In addition to diagonal bracing, the reinforcing ribs 307 can also include vertically extending vertical ribs. These vertical ribs can be vertically arranged between the second baffle 304 and the connecting beam 301, connected to the connecting support 306. Multiple diagonal bracings are distributed on both sides of the vertical ribs.

[0068] In this embodiment, the first baffle 302, the second baffle 304, etc. of the intake turbulence structure 30 form an integral structure, which is then assembled into the intake channel section for easy assembly. It is understood that, in order to achieve gas deflection within the intake channel section to reduce the entry of rain, snow, and other objects, the intake turbulence structure 30 is not limited to this. For example, the first baffle 302 and the second baffle 304 may not be connected, and the first baffle 302 may be fixed to the first air guide shroud 40. This embodiment does not impose such limitations, as long as they are fitted together within the intake channel section to form a first flow channel OB and a second flow channel OC with an angled extension direction.

[0069] In addition, in this embodiment, each part of the air intake turbulence structure 30 can be an integral structure, or it can be at least partially separated and then fixedly connected together.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
