Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0060] In the present disclosure, the orientation word "first direction" refers to a crimping direction of the first crimping edge to the first elastic flange and / or the second crimping edge to the second elastic flange, unless otherwise indicated, and can be specifically referred to Figure 4 and Figure 5As shown; for example, the first direction can be the up-down direction of the vehicle.

[0061] In the description of the present disclosure, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "arrangement", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0062] Referring to Figures 1 to 11 As shown, the present disclosure provides a flow channel assembly, which comprises a flow channel port component 1, a sealing member 2, and a grid member 3. The inside of the flow channel port component 1 is formed with a first flow channel 10, which comprises a first flow channel port 101 and a second flow channel port 102; the inside of the sealing member 2 is formed with a through communication flow channel 20, which comprises a first communication port 201 and a second communication port 202; the flow channel port component 1 can be sealingly connected with the sealing member 2 to sealingly communicate the second flow channel port 102 and the first communication port 201. Wherein, the grid member 3 is arranged on the flow channel port component 1 and located at the second flow channel port 102; and / or, the grid member 3 is arranged on the sealing member 2 and located at the first communication port 201.

[0063] In the above technical solution, first, the flow channel port component 1 can be sealingly connected with the sealing member 2, so as to realize the sealing communication between the first flow channel 10 inside the flow channel port component 1 and the communication flow channel 20 inside the sealing member 2; second, in order to prevent the impact of high-speed fluid or fluid containing large kinetic energy on the connection between the flow channel port component 1 and the sealing member 2, the grid member 3 arranged can effectively buffer the fluid, disperse the energy of the fluid, reduce the damage to the sealing connection between the flow channel port component 1 and the sealing member 2, and further ensure the sealing performance between the flow channel port component 1 and the sealing member 2.

[0064] Wherein, the grid member 3 can be arranged on the flow channel port component 1 and located at the second flow channel port 102; or, the grid member 3 can be arranged on the sealing member 2 and located at the first communication port 201; or, the grid member 3 is arranged at the second flow channel port 102 and the first communication port 201, which is not limited by the present disclosure.

[0065] For the fluid flowing into the first flow channel 10 and the communication flow channel 20, it can flow into the first flow channel 10 from the first flow channel port 101, flow through the first flow channel 10 and the communication flow channel 20, and then flow out from the second communication port 202; or it can flow into the communication flow channel 20 from the second communication port 202, flow through the communication flow channel 20 and the first flow channel 10, and then flow out from the first flow channel port 101. The present disclosure does not limit the above two cases.

[0066] In addition, for the fluid flowing into the first flow channel 10 and the communication flow channel 20, it can be water, but the present disclosure does not limit the specific type of the fluid.

[0067] Alternatively, for the flow channel assembly, two fluid media can flow through the first flow channel 10 and the communication flow channel 20. For example, the two fluid media can include water and air. The water can flow into the first flow channel 10 from the first flow channel port 101, flow through the first flow channel 10 and the communication flow channel 20, and then flow out from the second communication port 202; the air can flow into the communication flow channel 20 from the second communication port 202, flow through the communication flow channel 20 and the first flow channel 10, and then flow out from the first flow channel port 101. The grid member 3 can be used to buffer the water, prevent the water from damaging the seal between the flow channel port component 1 and the sealing member 2, and improve the sealing performance.

[0068] In an embodiment, referring to FIGS. 1 to Figure 5 The sealing member 2 includes a sealing member body 21 and a first sealing portion 22. The communication flow channel 20 is formed in the sealing member body 21. The first sealing portion 22 is arranged on the sealing member body 21 and located at the first communication port 201. The first sealing portion 22 can be sealingly connected with the flow channel port component 1 to seal the second flow channel port 102 and the first communication port 201. The grid member 3 is arranged on the first sealing portion 22 and / or the flow channel port component 1 and located at the second flow channel port 102.

[0069] In this embodiment, by arranging the first sealing portion 22 on the sealing member body 21 and positioning it at the first communication port 201, an effective seal can be formed when the sealing member 2 contacts the flow channel port component 1. The first sealing portion 22 can be constructed in any appropriate sealing structure and any appropriate shape, which is not limited by the present disclosure.

[0070] The grid member 3 can be arranged on the first sealing portion 22, arranged at the second flow channel port 102, or arranged on the first sealing portion 22 and the second flow channel port 102, which is not limited by the present disclosure.

[0071] For the purpose of sealing, the sealing body 21 and the first sealing part 22 can be configured as an integral structure to minimize the sealing of the connecting surface.

[0072] For the purpose of disassembly or partial replacement, the first sealing part 22 can also be detachably connected to the sealing body 21, of course, the sealing performance between the first sealing part 22 and the sealing body 21 should be ensured first, when the first sealing part 22 needs to be replaced due to damage, the entire sealing 2 does not need to be replaced, only the local first sealing part 22 needs to be replaced, which effectively reduces the cost.

[0073] Optionally, as shown in Figure 2 and Figure 5 , the first sealing part 22 can include a first elastic flange, the first elastic flange is arranged around the first communication port 201 and can elastically deform in the first direction A, and the flow passage port component 1 is used to be crimped on the first elastic flange in the first direction A; wherein the grid member 3 is arranged on the flow passage port component 1 and located at the second flow passage port 102.

[0074] In this embodiment, first, the first elastic flange is arranged around the first communication port 201 of the communication flow passage 20 and can elastically deform in the first direction A, and the first elastic flange can deform appropriately according to the crimping of the flow passage port component 1, which ensures the close fit between the contact surfaces, thereby greatly enhancing the reliability of the seal.

[0075] Secondly, the existence of the first elastic flange can allow certain assembly errors to exist, because it can adjust its shape during crimping to adapt to slight size deviations or irregular surfaces, so it can be more tolerant to small errors in the manufacturing and installation process.

[0076] And because the first elastic flange has the ability to elastically deform, it can act as a buffer when encountering external vibrations, preventing seal failure due to vibrations, further improving the stability of the seal.

[0077] In addition, when sealing, only the flow passage port component 1 needs to be crimped in place in the specified direction (i.e. the first direction A) to complete the sealing connection, without the need for additional steps such as tightening screws, making it easy to operate.

[0078] The choice and design of the elastic material can reduce the wear caused by hard impact, and the ability of elastic deformation also means that it can still maintain good sealing performance after being disassembled and assembled multiple times, thereby indirectly extending the service life of the sealing 2.

[0079] In another embodiment, referring to Figure 1 and Figure 2As shown, the flow channel opening component 1 comprises a component body 11 and a first crimping edge 12, the inside of the component body 11 is formed with the first flow channel 10, the first crimping edge 12 is arranged on the component body 11 and extends along the first direction A, and is arranged in the circumferential direction of the second flow channel opening 102 of the first flow channel 10, and the first crimping edge 12 is used for crimping the first elastic flange in the first direction A; wherein the grid piece 3 is arranged on the inner side of the first crimping edge 12 and connected with the first crimping edge 12.

[0080] In this embodiment, the first crimping edge 12 described above can be configured as a rigid structure, and the first crimping edge 12 arranged in the circumferential direction of the second flow channel opening 102 of the first flow channel 10 can uniformly apply force to the first elastic flange, thereby avoiding the problem of excessive local stress, preventing the first elastic flange from being permanently deformed or damaged due to excessive compression in a local area, and prolonging the service life of the sealing element 2. In addition, the first crimping edge 12 is specially designed to match the first elastic flange, which not only simplifies the installation process (only needs to apply appropriate pressure along the first direction A), but also ensures consistency and accuracy of each installation, and reduces errors caused by human factors. In addition, the grid piece 3 is arranged on the inner side of the first crimping edge 12 and connected with the first crimping edge 12, which facilitates the connection of the grid piece 3 and can effectively protect the grid piece 3.

[0081] In one embodiment, referring to Figure 2 and Figure 3 As shown, the grid piece 3 comprises at least one grid plate 31; the grid plate 31 is arranged on the flow channel opening component 1 and located at the second flow channel opening 102, and the grid plate 31 is arranged inclinedly relative to the second flow channel opening 102; and / or, the grid plate 31 is arranged on the sealing element 2 and located at the first communication opening 201, and the grid plate 31 is arranged inclinedly relative to the first communication opening 201.

[0082] In this embodiment, by arranging the grid plate 3 inclinedly relative to the second flow channel opening 102 and / or the first communication opening 201, the normal flow of the fluid in the first flow channel 10 and the communication flow channel 20 is ensured, and the fluid can be effectively buffered, thereby improving the sealing performance between the flow channel opening component 1 and the sealing element 2. In addition, the inclination direction of the grid plate 3 can be the same as the inclination direction of the first flow channel 10, thereby facilitating the effective flow guiding of the fluid.

[0083] Among them, the number of grid plates 31 can be one or multiple, and multiple grid plates 31 can be arranged alternately, which is not limited in the present disclosure.

[0084] Optionally, referring to Figure 1 and Figure 3As shown, the flow channel port component 1 comprises a flow channel port appearance piece 13 and a flow channel port connecting piece 14; the interiors of the flow channel port appearance piece 13 and the flow channel port connecting piece 14 are formed with flow channels, and the flow channel port appearance piece 13 and the flow channel port connecting piece 14 are sealingly connected to define the first flow channel 10; an end of the flow channel port appearance piece 13 away from the flow channel port connecting piece 14 is configured as a first flow channel port 101, and an end of the flow channel port connecting piece 14 away from the flow channel port appearance piece 13 is configured as a second flow channel port 102; wherein the grid piece 3 is arranged on the flow channel port connecting piece 14 and located at the second flow channel port 102. The design that the flow channel port appearance piece 13 and the flow channel port connecting piece 14 are separated from each other can make each structural piece be independently manufactured, maintained or replaced according to specific requirements, and facilitate the maintenance or replacement of each structural piece.

[0085] Optionally, referring to Figure 3 As shown, the grid piece 3 can be integrally formed with the flow channel port connecting piece 14, that is, the grid piece 3 is integrally arranged at the second flow channel port 102 of the flow channel port connecting piece 14. For example, the grid piece 3 and the flow channel port connecting piece 14 are integrally injection molded by using plastic material, but the specific material and the specific molding method of the grid piece 3 and the flow channel port connecting piece 14 are not limited in the present disclosure.

[0086] In addition, the sealing piece 2 described above can be integrally formed by using elastic material, for example, the sealing piece 2 can be integrally formed by using rubber material, but the specific material of the sealing piece 2 is not limited in the present disclosure.

[0087] Optionally, the first flow channel 10 is gradually expanded in a direction away from the communication flow channel 20, which can facilitate the outflow of the flowing medium, and the first flow channel 10 is gradually expanded in a direction close to the communication flow channel 20, which can facilitate the inflow of the flowing medium.

[0088] For example, the opening area of the first flow channel 10 away from the communication flow channel 20 is a first area, and the opening area of the first flow channel 10 close to the communication flow channel 20 is a second area, and the first area is 1-2 times of the second area.

[0094] In the above technical solution, the flow passage port component 1 and the sealing member 2 are arranged at the cover opening 40 of the front hood 4 of the vehicle. When the vehicle is washed, high-pressure water will enter the first flow passage 10 and the communication flow passage 20, and damage the sealing part of the flow passage port component 1 and the sealing member 2. By arranging the grid member 3, the water can be effectively buffered, the energy of the water can be dispersed, the damage to the sealing connection part of the flow passage port component 1 and the sealing member 2 can be reduced, and the sealing performance between the flow passage port component 1 and the sealing member 2 can be ensured.
