[Modes for carrying out the invention]

[0038] Hereinafter, exemplary embodiments are described in detail and illustrated in the drawings. Where the following description relates to the drawings, unless otherwise stated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application, which are described in detail in the appended claims.

[0039] In this disclosure, unless otherwise specified, the directional terms "first direction, second direction, and third direction" refer to three intersecting directions, specifically, the first direction, second direction, and third direction may be perpendicular to each other in pairs, as can be seen in Figure 1.

[0040] The directional terms used, such as "inside" and "outside," refer to the inside and outside of a specific structural contour; the terms used, such as "first" and "second," are solely for distinguishing one element from another and do not imply any order or importance; and "multiple" in this application refers to and includes two or more.

[0041] In the descriptions of this disclosure, unless explicitly stated and limited, “configuration” and “connection” should be understood in a broad sense, for example, a fixed connection, a removable connection, an integral connection, a direct connection, or an indirect connection via an intermediate medium. Those skilled in the art will be able to understand the specific meaning of the above terms in this disclosure depending on the specific circumstances.

[0042] As shown in Figures 1 to 12, the present disclosure provides a flow path assembly comprising a first flow path member 1 and a second flow path member 2. A first flow path 10 is formed inside the first flow path member 1, and the first flow path 10 has a first flow path opening 101 and a second flow path opening 102. A second flow path 20 is formed inside the second flow path member 2, and the second flow path 20 has a third flow path opening 201 and a fourth flow path opening 202, and the second flow path opening 102 is used to communicate with the fourth flow path opening 202, thereby connecting the first flow path 10 and the second flow path 20 and having at least a first flow path route. In this first flow path route, the third flow path opening 201 is for introducing a first fluid medium, and the first flow path opening 101 is for releasing the first fluid medium.

[0043] In the above proposed technology, when the first flow path 10 of the first flow path member 1 and the second flow path 20 of the second flow path member 2 are in communication with each other, that is, when the second flow opening 102 of the first flow path 10 and the fourth flow opening 202 of the second flow path 20 are in communication with each other, at least a first flow path can be formed. In this first flow path, the first fluid medium flows in from the third flow opening 201, flows sequentially through the second flow path 20 and the first flow path 10, and finally flows out from the first flow opening 101. In other words, with the first flow path member 1 and the second flow path member 2 provided in this manner, the first fluid medium can flow through the first flow path 10 and the second flow path 20, ensuring the smooth discharge of the fluid medium.

[0044] For example, the first fluid medium described above can be configured as air, and this flow path assembly is applicable to a vehicle and is positioned in the front cabin of the vehicle to allow air to flow in, thereby reducing air resistance as much as possible and improving the aerodynamic performance of the vehicle. However, this disclosure does not limit the specific type of the first fluid medium, nor does it limit the specific application scenarios of the flow path assembly.

[0045] Selectively, the second flow path 20 may further have at least one fifth flow port 203, and the first flow path 10 and the second flow path 20 may further have a second flow path route when they are in communication, and in the second flow path route, the fifth flow port 203 may be for discharging a second fluid.

[0046] In other words, when the first flow path 10 and the second flow path 20 are in communication, that is, when the second flow path opening 102 and the fourth flow path opening 202 are in communication, the first flow path 10 and the second flow path 20 further have a second flow path, in which the second fluid flows in from the first flow path opening 101, flows sequentially through the first flow path 10 and the second flow path 20, and then flows out from the fifth flow path opening 203.

[0047] In other words, the first flow channel member 1 and the second flow channel member 2, as provided in this manner, allow both the first fluid medium and the second fluid medium to flow through the first flow channel 10 and the second flow channel 20, ensuring the smooth discharge of the two types of media and minimizing interference between them as much as possible.

[0048] Selectively, the first fluid medium may be air, and the second fluid medium may be water.

[0049] In another embodiment, the flow path assembly may further comprise a third flow path member (not shown) having a third flow path formed inside the third flow path member (not shown), the third flow path having a sixth flow path opening (not shown) and a seventh flow path opening (not shown), the sixth flow path opening being used to communicate with a second flow path opening 102 to connect the first flow path 10 and the third flow path, the first flow path opening 101 being for introducing the second fluid medium and the seventh flow path opening being for releasing the second fluid medium.

[0050] In other words, for the first fluid medium, it flows in from the second flow path 20 and flows out from the first flow path 10, and for the second fluid medium, after flowing out from the first flow path 10, it does not flow into the second flow path 20, and the third flow path member provided in this way allows the second fluid medium that has flowed out from the first flow path 10 to flow into the third flow path and be discharged, thereby reducing interference between the first fluid medium and the second fluid medium as much as possible.

[0051] Selectively, as shown in Figures 1 and 2, one of the first flow channel member 1 and the second flow channel member 2 is movable relative to the other, and they have a communication position, in which the second flow channel opening and the fourth flow channel opening are provided facing each other and communicate with one another.

[0052] In this embodiment, the first flow path member 1 may move relative to the second flow path member 2, or the second flow path member 2 may move relative to the first flow path member 1, and this disclosure is not limited thereto. Furthermore, when the first flow path member 1 and the second flow path member 2 are in a communication position, the second flow path opening 102 of the first flow path 10 and the fourth flow path opening 202 of the second flow path 20 are provided facing each other and are in communication with each other.

[0053] Selectively, the first flow path member 1 is movable relative to the second flow path member 2. For example, the first flow path member 1 can be provided on a first external member, and the second flow path member 2 can be provided on a second external member. For example, the first external member is movably connected to the second external member, and this movable configuration includes, but is not limited to, a rotatable configuration and a movable configuration. When the first flow path member 1 moves to a communication position following the first external member, the first flow path member 1 and the second flow path member 2 communicate with each other. When the first flow path member 1 is not in a communication position relative to the second flow path member 2, the second flow opening 102 of the first flow path member 1 and the fourth flow opening 202 of the second flow path member 2 do not need to communicate.

[0054] Selectively, as shown in Figures 2 to 4, the first grid 3 may be provided at the second flow port 102 of the first flow channel member 1, and / or the first grid 3 may be provided at the fourth flow port 202 of the second flow channel member 2. In this embodiment, the first grid 3 may be provided at the second flow port 102, or at the fourth flow port 202, or at both the second flow port 102 and the fourth flow port 202, and this disclosure is not limited thereto. Furthermore, the first grid 3 can guide the first fluid medium and the second fluid medium and can function as a buffer for at least one of the first and second fluid mediums. For example, if the first fluid medium is air and the second fluid medium is water, the first grid 3 can guide the air and perform a drainage function, as well as function as a buffer for the water.

[0055] Furthermore, a second grid 4 can be provided at the fifth flow channel opening 203 of the second flow channel member 2. This second grid 4 can guide the inflow of the second fluid medium and, to some extent, prevent the first fluid medium from flowing into this fifth flow channel opening 203.

[0056] Selectively, as shown in Figures 2 to 4, the first grid 3 may have at least one first grid plate 31, the first grid plate 31 being provided at the second flow port 102 and inclined with respect to the second flow port 102, and / or, the first grid 3 may have at least one first grid plate 31, the first grid plate 31 being provided at the fourth flow port 202 and inclined with respect to the fourth flow port 202, and / or, the second grid 4 may have at least one second grid plate 41, the second grid plate 41 being inclined with respect to the fifth flow port 203.

[0057] In this embodiment, by providing the grid plate at an inclination with respect to the corresponding flow channel opening 102, the fluid can be effectively buffered while ensuring the normal flow of the fluid medium.

[0058] For example, multiple first grid plates 31 are provided, with two adjacent first grid plates 31 spaced apart, and the multiple first grid plates 31 are parallel to each other; multiple second grid plates 41 are provided, with two adjacent second grid plates 41 spaced apart, and the multiple second grid plates 41 are parallel to each other; and the first grid plates 31 and the second grid plates 41 are parallel to each other.

[0059] In this embodiment, both the first grid plate 31 and the second grid plate 41, which are parallel to each other, guide the second fluid medium so that the second fluid medium can flow in the second flow path. Furthermore, the first grid plate 31 can guide the first fluid medium, and the second grid plate 41 can prevent the first fluid medium from flowing into the fifth flow port 203 to some extent. In addition, it is possible to ensure that the first flow path and the second flow path do not interfere with each other and operate synchronously.

[0060] This disclosure does not limit the specific number of the first grid plate 31 and the second grid plate 41, and in other embodiments, the first grid plate 31 and the second grid plate 41 may be provided as one and parallel to each other.

[0061] As shown in Figures 1 to 3, the first flow path 10 has a first flow path segment 103 and a second flow path segment 104 that communicate with each other, and the first flow path member 1 has a first flow path component 11 and a second flow path component 12, the first flow path segment 103 is formed inside the first flow path component 11 and the second flow path segment 104 is formed inside the second flow path component 12, one end of the first flow path segment 103 away from the second flow path segment 104 is configured as a first flow path opening 101 and the other end of the second flow path segment 104 away from the first flow path segment 103 is configured as a second flow path opening 102.

[0062] By dividing the flow path into two parts and placing them on different components, the position of each component can be flexibly adjusted according to the actual installation environment, allowing for better adaptation to spatial constraints in different application scenarios. This not only improves the versatility and adaptability of the product but also saves some installation space.

[0063] Selectively, as shown in Figure 3, a third grid 5 may be provided at one end of the first flow channel segment 103 that is close to the second flow channel segment 104, and / or a third grid 5 may be provided at one end of the second flow channel segment 104 that is close to the first flow channel segment 103.

[0064] In this embodiment, by providing the third grid 5, the third grid 5 can guide the first fluid medium and the second fluid medium, and can buffer at least one of the first fluid medium and the second fluid medium, thereby preventing damage to the sealing performance of structural members or between structures due to the inflow of a high-speed or high-momentum medium.

[0065] In another configuration, referring to Figures 3 and 4, a first grid 3 is provided at the second flow channel opening 102, the first grid 3 has at least one first grid plate 31, the first grid plate 31 is inclined with respect to the second flow channel opening 102, a second grid 4 is provided at the fifth flow channel opening 203, the second grid 4 includes at least one second grid plate 41, the second grid plate 41 is inclined with respect to the fifth flow channel opening 203, and a third grid 5 has at least one third grid plate 51, the third grid plate 51 is inclined with respect to one end of the first flow channel segment 103 that is close to the second flow channel segment 104, and the first grid plate 31, the second grid plate 41 and the third grid plate 51 are parallel to each other. These parallel first grid plates 31, second grid plate 41, and third grid plate 51 ensure that the first fluid medium in the first flow path and the second fluid medium in the second flow path flow according to their respective paths, thereby avoiding interference between them.

[0066] Selectively, referring to Figures 7 and 8, the second flow channel component 12 is configured as a sealing member and has a sealing member body 121, a first sealing portion 122 and a second sealing portion 123. A second flow channel segment 104 is formed inside the sealing member body 121. The first sealing portion 122 is provided on the sealing member body 121 and is located at the first end of the second flow channel segment 104. The first sealing portion 122 is sealedly connected to the first flow channel component 11, allowing the first flow channel segment 103 and the second flow channel segment 104 to communicate in a sealed manner. The second sealing portion 123 is provided on the sealing member body 121 and is located at the second end of the second flow channel segment 104. The second sealing portion 123 is sealedly connected to the second flow channel member 2, allowing the second flow channel segment 104 and the second flow channel 20 to communicate in a sealed manner.

[0067] In this embodiment, the provided first sealing portion 122 and second sealing portion 123 achieve sealing performance between both ends of the sealing member and the first flow path component 11 and the second flow path component 2, thereby preventing leakage of gas or liquid and improving sealing performance.

[0068] Considering the sealing performance, the sealing member body 121, the first sealing portion 122, and the second sealing portion 123 can be configured as an integrated structure, thereby reducing the sealing required for the connection surface as much as possible.

[0069] Considering removable or partial replacement, the first seal portion 122 and the second seal portion 123 can be detachably connected to the seal member body 121. Of course, it is necessary to first ensure the sealing performance between the first seal portion 122, the second seal portion 123 and the seal member body 121. If the first seal portion 122 or the second seal portion 123 is damaged and needs to be replaced, it is not necessary to replace the entire seal member, but only the first seal portion 122 or the second seal portion 123 needs to be replaced, thus effectively reducing costs.

[0070] Furthermore, the first sealing portion 122 and the second sealing portion 123 described above can be configured in any suitable shape and structure, and this disclosure does not limit them, nor does this disclosure limit the specific materials of the first sealing portion 122 and the second sealing portion 123.

[0071] In this embodiment, referring to Figures 3, 7, and 8, the first seal portion 122 may have a first elastic flange, the first elastic flange being positioned circumferentially at the first end of the second flow channel segment 104 and elastically deformable along a first direction A, and the first flow channel component 11 being configured to be pressed against the first elastic flange in the first direction A.

[0072] In this embodiment, first, the first elastic flange is positioned circumferentially at the first end of the second flow channel segment 104 and is elastically deformable along the first direction A. This first elastic flange can deform appropriately according to the pressing conditions of the first flow channel component 11, ensuring tight contact between the contact surfaces and thereby significantly improving the reliability of the seal.

[0073] Next, the presence of the first elastic flange allows for a certain degree of assembly error, as it adjusts its shape during the pressing process to adapt to slight dimensional deviations or irregular surfaces, thereby providing greater tolerance for small errors in the manufacturing and installation processes.

[0074] Furthermore, because the first elastic flange has elastic deformation capability, it acts as a buffer when it encounters external vibrations, preventing seal failure due to vibration and further improving the stability of the seal.

[0075] Furthermore, when performing sealing, the sealing connection is completed simply by pressing the first flow path component 11 in the specified direction, eliminating the need for additional operating steps such as tightening screws, thus making the operation easy.

[0076] By selecting and designing elastic materials, wear caused by hard impacts can be reduced. At the same time, the ability to undergo elastic deformation means that good sealing performance can be maintained even after multiple removals, thereby indirectly extending the service life of the sealing component.

[0077] In other embodiments, referring to Figures 3, 7, and 8, the second seal portion 123 may have a second elastic flange, the second elastic flange being positioned circumferentially at the second end of the second flow channel segment 104 and elastically deformable along the first direction A, and the second flow channel member 2 being configured to be pressed against the second elastic flange in the first direction A.

[0078] In this embodiment, first, the second elastic flange is positioned circumferentially at the second end of the second flow channel segment 104 and is elastically deformable along the first direction A. This second elastic flange can deform appropriately according to the pressure applied to the second flow channel member 2, ensuring tight contact between the contact surfaces and thereby significantly improving the reliability of the seal.

[0079] Next, the presence of a second elastic flange allows for a certain degree of assembly error, as it adjusts its shape during the pressing process to adapt to slight dimensional deviations or irregular surfaces, thereby providing greater tolerance for small errors in the manufacturing and installation processes.

[0080] Furthermore, because the second elastic flange has elastic deformation capability, it acts as a buffer when it encounters external vibrations, preventing seal failure due to vibration and further improving the stability of the seal.

[0081] Furthermore, when performing sealing, the sealing connection is completed simply by pressing the second elastic flange and the second flow path member 2 in the specified direction, eliminating the need for additional operating steps such as tightening screws, thus making the operation easy.

[0082] By selecting and designing elastic materials, wear caused by hard impacts can be reduced. At the same time, the ability to undergo elastic deformation means that good sealing performance can be maintained even after multiple removals, thereby indirectly extending the service life of the sealing component.

[0083] Selectively, referring to Figure 3, the first flow channel component 11 has a first body 111 and a first pressure connection edge 112, wherein a first flow channel segment 103 is formed inside the first body 111, and the first pressure connection edge 112 is provided on the first body 111 so as to extend along a first direction A, and is positioned circumferentially at one end of the first flow channel segment 103, and the first pressure connection edge 112 may be configured to press against a first elastic flange in the first direction A.

[0084] In this embodiment, the first pressure connection edge 112 can be configured as a rigid structure, and positioned circumferentially at one end of the first flow channel segment 103, this first pressure connection edge 112 can uniformly apply biasing force to the first elastic flange, thereby avoiding the problem of partial stress overload, preventing permanent deformation or damage to the first elastic flange due to excessive compression of a portion, and extending the service life of the sealing member. Furthermore, this first pressure connection edge 112 is professionally designed to work in combination with the first elastic flange, thereby not only simplifying the installation process (only requiring the application of appropriate pressure along the first direction A) but also ensuring consistency and accuracy in each installation and reducing errors due to human factors.

[0085] Selectively, referring to Figure 3, the second flow channel member 2 has a second body 21 and a second pressure connection edge 22, a second flow channel 20 is formed inside the second body 21, the second pressure connection edge 22 is provided on the second body 21 so as to extend along the first direction A, is positioned circumferentially to the fourth flow channel opening 202 of the second flow channel 20, and the second pressure connection edge 22 may be configured to be pressed against the second elastic flange in the first direction A.

[0086] In this embodiment, the second pressure connection edge 22 can be configured as a rigid structure, and this second pressure connection edge 22, positioned circumferentially around the fourth flow channel opening 202, can uniformly apply biasing force to the second elastic flange, thereby avoiding the problem of partial excessive stress, preventing permanent deformation or damage to the first elastic flange due to excessive compression of a portion, and extending the service life of the sealing member. Furthermore, this second pressure connection edge 22 is professionally designed to work in combination with the second elastic flange, thereby not only simplifying the installation process (only requiring the application of appropriate pressure along the first direction A), but also ensuring consistency and accuracy in each installation and reducing errors due to human factors.

[0087] Referring to Figures 3, 7, and 8, the sealing member may further have a third sealing portion 124, which is provided on the sealing member body 121 and used to seally connect with an external member.

[0088] In other words, in this embodiment, when the sealing member is provided on the external member, it is also necessary to ensure the sealing performance between the sealing member and the external member, and this third sealing portion 124 can effectively achieve a seal between the sealing member and the external member. This third sealing portion 124 can be configured in any suitable shape and structure, and this disclosure is not limited thereto.

[0089] For example, the third seal portion 124 has a seal engagement groove, which is recessed in the outer wall of the seal member body 121 and used to engage airtightly with an external member, and / or the third seal portion 124 has a seal engagement block, which is provided protruding from the outer wall of the seal member body 121 and used to engage airtightly with an external member. That is, the airtight engagement configuration reduces the number of components to be installed and also enables an airtight connection between the seal member and the external member. When the flow path assembly is applied to a vehicle, this external member may be the front cabin interior plate 62.

[0090] The second flow channel component 12, which is selectively configured as the sealing member, may be integrally molded from an elastic material. For example, the second flow channel component 12 may be integrally molded from a rubber material, but this disclosure does not limit the specific material of the second flow channel component 12.

[0091] Referring to Figures 2, 5, 6, and 12, the second flow path 20 has a second flow path body 2001, and the second flow path member 2 has a first flow path plate 23 and a second flow path plate 24, the first flow path plate 23 and the second flow path plate 24 are butted together and connected in the first direction A, defining the second flow path body 2001 extending along the second direction B. The first flow path member 1 is provided on one side of the first flow path plate 23 away from the second flow path plate 24 in the first direction A, the fourth flow path opening 202 is formed in the first flow path plate 23, and the fifth flow path opening 203 is formed in the second flow path plate 24. In the second direction B, the fifth flow path opening 203 is provided between the third flow path opening 201 and the fourth flow path opening 202, and is provided where the first direction A intersects the second direction B.

[0092] In this embodiment, the first fluid medium flows in from the third flow channel opening 201, enters the second flow channel body 2001 and the first flow channel 10, and finally flows out from the first flow channel opening 101. The second fluid medium flows in from the first flow channel opening 101, flows sequentially through the first flow channel 10 and the second flow channel body 2001, and then flows out from the fifth flow channel opening 203. Furthermore, by providing the fifth flow channel opening 203 between the third flow channel opening 201 and the fourth flow channel opening 202 in the second direction B, it is possible to effectively prevent the second fluid medium from flowing out from the third flow channel opening 201.

[0093] For example, in a specific application scenario, this flow path assembly can be applied to a vehicle and placed in the vehicle's front cabin. The first flow path configured as described above is used as a gas flow path, thereby improving the vehicle's aerodynamic performance. The second flow path configured as described above is used as a drainage passage. The third flow port 201 can be placed in the vehicle's front side light and positioned to face forward for intake. As can be seen from the above, by providing the fifth flow port 203 between the third flow port 201 and the fourth flow port 202 in the second direction B, the second fluid medium can be effectively prevented from flowing out of the third flow port 201, that is, water can be effectively prevented from flowing out of the front side light, avoiding the problem of "water flowing" into the front side light, enabling drainage within the front cabin, and improving the user experience.

[0094] Selectively, multiple fifth flow channels 203 may be provided, and the multiple fifth flow channels 203 are spaced apart in the second direction B, thereby improving the drainage effect and minimizing the inflow of water into the third flow channel 201.

[0095] Selectively, the second flow channel member 2 may further have a sealing component (not shown) provided between the first flow channel plate 23 and the second flow channel plate 24 to improve the sealing performance between the first flow channel plate 23 and the second flow channel plate 24. This sealing component may be configured as a sealing strip, but this disclosure does not limit the specific material of the sealing component.

[0096] As shown in Figure 12, the second flow path 20 further has a grooved flow path 2002 that communicates with the second flow path body 2001, the second flow path member 2 further has an end structural member 26, the end structural member 26 has a groove 261 that extends along the second direction B, the second flow path plate 24 is connected to the end structural member 26, and the first flow path plate 23 is connected to the end structural member 26 and covers the groove 261 to form a grooved flow path 2002, and the end of the grooved flow path 2002 away from the second flow path body 2001 is configured as a third flow path opening 201.

[0097] In this embodiment, by introducing a grooved flow channel 2002 and providing one end there as a third flow channel opening 201, it is possible to effectively control the fluid flow path, for example, when it is necessary to change the direction of the fluid or to divert the flow.

[0098] This end structural member 26 can be configured as any suitable structure; for example, it can be configured as a mounting frame for the front side light of a vehicle, and by using structural components of the vehicle itself to form the recessed air passage 2002 for intake, the number of parts to be installed is reduced, costs are lowered, and the compactness of the structural design is improved.

[0099] Selectively, referring to Figure 3, the first flow channel segment 103 may have a shape that gradually expands away from the second flow channel segment 104. This facilitates the outflow of the first fluid and facilitates the inflow of the second fluid.

[0100] For example, the opening area at one end of the first flow channel segment 103 that is far from the second flow channel segment 104 is the first area, the opening area at the other end of the first flow channel segment 103 that is close to the second flow channel segment 104 is the second area, and the first area is 1 to 2 times the second area.

[0101] Selectively, the length of the second channel 20 may be 1 to 1.5 times the length of the first channel segment 103.

[0102] Selectively, the extension direction of the first flow path 10 may be provided so as to intersect with the extension direction of the second flow path 20, thereby satisfying the need for the fluid to flow in different directions.

[0103] The disclosure further provides a vehicle comprising a front cabin cover 6 and the above-described flow path assembly, wherein a second flow path member 2 is provided inside the front cabin, a third flow path opening 201 of the second flow path 20 is positioned forward and used to communicate with the outside, a cover plate opening is formed in the front cabin cover 6, a first flow path member 1 is provided inside the cover plate opening, a first flow path opening 101 of the first flow path 10 is used to communicate with the outside, and when the front cabin cover 6 is closed, a second flow path opening 102 of the first flow path member 1 and a fourth flow path opening 202 of the second flow path member 2 communicate with each other.

[0104] In other words, the above-described flow path assembly can be applied to a vehicle and placed in the front cabin of the vehicle to be used as a flow path for gas, thereby improving the aerodynamic performance of the vehicle. At the same time, this flow path assembly can also serve as a drainage passage to ensure the normal operation of the flow path assembly in operating conditions such as rainy days, but this disclosure does not limit the specific application scenarios of the above-described flow path assembly.

[0105] Referring to Figures 9 to 11, the front cabin cover 6 has a front cabin outer plate 61 and a front cabin inner plate 62, the front cabin outer plate 61 and the front cabin inner plate 62 are connected to each other to define a cover plate cavity 60, an outer plate opening 610 is formed in the front cabin outer plate 61 and an inner plate opening 620 is formed in the front cabin inner plate 62, at least a part of the first flow path member 1 is provided in the cover plate cavity 60, the first flow path member 1 is sealedly connected to the outer plate opening 610 and the first flow path member 1 is sealedly connected to the inner plate opening 620, preventing fluid from entering the cover plate cavity 60 and improving sealing performance.

[0106] Selectively, the second flow path 20 may extend along the longitudinal direction, and the first flow path 10 may extend diagonally upward in a direction away from the second flow path 20.

[0107] Specifically, the first channel 10 extends diagonally upward and backward in a direction away from the second channel 50, and the angle at which the first channel 10 is inclined with respect to the horizontal plane is 30 degrees or less. This included angle is the angle behind the first channel 10 and the horizontal plane, that is, this included angle is the acute angle between the first channel 10 and the horizontal plane.

[0108] Furthermore, as can be seen from the above, the first flow channel member 1 has a first flow channel component 11 and a second flow channel component 12, and the first flow channel segment 103 within the first flow channel component 11 can extend diagonally upward and backward, and the angle of inclination with respect to the horizontal plane is 30 degrees or less.

[0109] Based on this, the first grid plate 31, the second grid plate 41, and the third grid plate 51 may not only be parallel to each other, but also parallel to the first flow channel segment 103, thereby facilitating not only the airflow along the direction of air discharge, but also the discharge and buffering of water.

[0110] Selectively, the first flow path member may be positioned close to the outside in the lateral direction of the vehicle, and / or the second flow path member 2 may be positioned close to the outside in the lateral direction of the vehicle.

[0111] Selectively, two flow path assemblies may be provided, one positioned close to the left outer side of the vehicle and the other close to the right outer side of the vehicle. Placing flow path assemblies on both the left and right sides of the vehicle more effectively improves the vehicle's aerodynamic performance.

[0112] A person skilled in the art, having reviewed the specification and put the disclosure into practice, will readily conceive of other embodiments of the disclosure. This application is intended to cover any variations, uses, or appropriate modifications of the disclosure, which will adhere to the general principles of the disclosure and include common or conventional art means of the art not disclosed herein.
