[0059] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements throughout the description. The following exemplary embodiments are not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0060] In the present disclosure, the directional term "first direction" used without a contrary indication refers to the crimping direction of the first crimping edge to the first elastic flange and / or the crimping direction of the second crimping edge to the second elastic flange, and can be specifically referred to in Figure 6 and Figure 7For example, the first direction can be the up-down direction of the vehicle. In addition, the orientation words such as "up, down, front, back, left, right" refer to the up, down, front, back, left, and right of the vehicle, which can be specifically referred to Figure 8 The orientation words such as "inner, outer" refer to the inner and outer of the specific structure profile, and the terms such as "first, second" are only used to distinguish one element from another element and do not have sequential and important meanings, and the plurality of the present application refers to two or more and includes two.

[0061] In the description of the present disclosure, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood in a broad sense, for example, can be fixedly connected, can be detachably connected, or integrally connected; 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 10 The present disclosure provides a flow passage assembly, which comprises a flow passage port component 1, a first flow passage 10 is formed inside; a flow passage piece 2, a second flow passage 20 is formed inside; a sealing piece 3, a communication flow passage 30 is formed inside, and is used to be arranged between the flow passage port component 1 and the flow passage piece 2. Wherein, one of the flow passage port component 1 and the flow passage piece 2 can move relative to the other and has a communication position, at the communication position, the first end of the communication flow passage 30 can be in sealed communication with the first flow passage 10, and the second end of the communication flow passage 30 can be in sealed communication with the second flow passage 20.

[0063] In the above technical solution, by arranging the sealing piece 3 between the flow passage port component 1 and the flow passage piece 2, at the communication position, the first end of the communication flow passage 30 is in sealed communication with the first flow passage 10, and the second end of the communication flow passage 30 is in sealed communication with the second flow passage 20, so that the sealing piece 3 is arranged to realize the sealed communication between the first flow passage 10 inside the flow passage port component 1 and the second flow passage 20 in the flow passage piece 2, thereby improving the sealing performance of the flow passage assembly, and avoiding the problems of air leakage, water leakage and the like at the communication position of the flow passage port component 1 and the flow passage piece 2.

[0064] Optionally, the flow passage port component 1 can move relative to the flow passage component 2, for example, the flow passage port component 1 can be arranged on a first external member, and the flow passage component 2 can be arranged on a second external member. For example, the first external member can be movably connected to the second external member, and the movable connection includes but is not limited to rotatable, movable, etc. When the flow passage port component 1 moves to the connected position along with the first external member, the sealing member 3 can achieve the sealing connection between the flow passage port component 1 and the flow passage component 2, thereby improving the sealing performance. When the flow passage port component 1 is not in the connected position relative to the flow passage component 2, the sealing member 3 can not achieve the connection between the flow passage port component 1 and the flow passage component 2, and the flow passage port component 1 and the flow passage component 2 can be independent of each other.

[0065] In a specific use scenario, the flow passage assembly can be applied to a vehicle and arranged at the front compartment of the vehicle to serve as a flow passage for gas flow, thereby improving the aerodynamic performance of the vehicle. For example, a cover plate opening can be formed on the front compartment cover 4 of the vehicle, the flow passage port component 1 is arranged in the cover plate opening and connected with the front compartment cover 4, and the sealing member 3 can also be connected with the front compartment cover 4 and sealingly connected with the flow passage port component 1. The flow passage component 2 can be arranged in the front compartment in the front-rear direction, the inlet of the second flow passage 20 can be arranged at the front of the vehicle and arranged forwardly for air intake, and the outlet of the second flow passage 20 is arranged behind the inlet and is used to communicate with the flow passage port component 1 through the sealing member 3. When the front compartment cover 4 is closed, the flow passage port component 1 can be in the connected position relative to the flow passage component 2, and the connection between the flow passage port component 1 and the flow passage component 2 can be achieved through the sealing member 3, thereby ensuring the sealing performance.

[0066] Of course, the present disclosure does not limit the specific application scenario of the flow passage assembly described above, for example, in other embodiments, the flow passage assembly can also be applied to the air inlet duct of an air conditioning device, and can also be applied to the air inlet duct of an engine, etc., and the present disclosure does not limit this.

[0067] Taking the air conditioning device as an example, the flow passage port component 1 can be arranged at the air inlet of the air conditioning device, and the flow passage component 2 can be arranged inside the air conditioning device. When the air conditioning device is in the air intake working condition, the flow passage port component 1 and the flow passage component 2 can be connected through the sealing member 3, thereby realizing the air intake function. When the air conditioning device is not in the air intake working condition, the flow passage port component 1 and the flow passage component 2 can not be connected, and the present disclosure does not limit this.

[0068] Optionally, the sealing member 3 can be connected to the flow passage port component 1, or the sealing member 3 can be connected to the flow passage component 2, or the sealing member 3 can be divided into two parts, one part is connected to the flow passage port component 1, and the other part is connected to the flow passage component 2, and the present disclosure does not limit this.

[0069] In one embodiment, referring to Figure 6 and Figure 7 shown, the sealing member 3 can include a sealing member body 31, a first sealing portion 32, and a second sealing portion 33; the sealing member body 31 has a communication flow channel 30 formed therein; the first sealing portion 32 is arranged on the sealing member body 31 and located at a first end of the communication flow channel 30, and the first sealing portion 32 is capable of being sealingly connected with the flow channel port member 1 to seal the communication between the first flow channel 10 and the communication flow channel 30; the second sealing portion 33 is arranged on the sealing member body 31 and located at a second end of the communication flow channel 30, and the second sealing portion 33 is capable of being sealingly connected with the flow channel member 2 to seal the communication between the second flow channel 20 and the communication flow channel 30.

[0070] In this embodiment, the first sealing portion 32 and the second sealing portion 33 are arranged to achieve the sealing performance between the two ends of the sealing member 3 and the flow channel port member 1 and the flow channel member 2, thereby preventing the leakage of gas or liquid and improving the sealing performance.

[0071] For the purpose of sealing, the sealing member body 31, the first sealing portion 32, and the second sealing portion 33 can be configured as an integrated structure to minimize the sealing of the connecting surface.

[0072] For the purpose of detachable or partial replacement, the first sealing portion 32 and the second sealing portion 33 can be detachably connected to the sealing member body 31, and of course, the sealing performance between the first sealing portion 32, the second sealing portion 33, and the sealing member body 31 should be ensured first; when the first sealing portion 32 or the second sealing portion 33 needs to be replaced due to damage, the entire sealing member 3 does not need to be replaced, and only the first sealing portion 32 or the second sealing portion 33 needs to be replaced, thereby effectively reducing the cost.

[0073] In addition, the first sealing portion 32 and the second sealing portion 33 described above can be configured in any appropriate shape and structure, and the present disclosure does not limit the same; in addition, the present disclosure does not limit the specific material of the first sealing portion 32 and the second sealing portion 33.

[0074] Optionally, referring to Figures 1 to 3 , and Figure 10 shown, the first sealing portion 32 described above can include a first elastic flange arranged in the circumferential direction of the first end of the communication flow channel 30 and capable of being elastically deformed in the first direction A, and the flow channel port member 1 is used to be crimped on the first elastic flange in the first direction A.

[0075] In this embodiment, first, the first elastic flange is arranged in the circumference of the first end of the communicating flow channel 30 and can be elastically deformed in the first direction A. The first elastic flange can be deformed appropriately according to the crimping of the flow channel port component 1, ensuring the close fit between the contact surfaces, thereby greatly enhancing the reliability of the seal.

[0076] 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, thereby being more tolerant of small errors in the manufacturing and installation process.

[0077] Moreover, since 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 enhancing the stability of the seal.

[0078] In addition, when sealing, only the flow channel port component 1 needs to be crimped in place in the specified direction to complete the sealing connection, without the need for additional steps such as tightening screws, making it easy to operate.

[0079] The choice and design of the elastic material can reduce wear caused by hard impact, and the ability to elastically deform also means that it can maintain good sealing performance after multiple disassembly and assembly, thereby indirectly extending the service life of the seal 3.

[0080] In another embodiment, referring to Figures 1 to 3 , the second seal portion 33 includes a second elastic flange arranged in the circumference of the second end of the communicating flow channel 30 and capable of being elastically deformed in the first direction A, and the flow channel member 2 is used to be crimped on the second elastic flange in the first direction A.

[0081] In this embodiment, first, the second elastic flange is arranged in the circumference of the second end of the communicating flow channel 30 and can be elastically deformed in the first direction A. The second elastic flange can be deformed appropriately according to the crimping of the flow channel member 2, ensuring the close fit between the contact surfaces, thereby greatly enhancing the reliability of the seal.

[0082] Secondly, the existence of the second 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, thereby being more tolerant of small errors in the manufacturing and installation process.

[0083] Moreover, since the second 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 enhancing the stability of the seal.

[0084] In addition, when sealing, only need to follow the specified direction to press the second elastic flange and flow channel piece 2 in place to complete the sealing connection, without additional steps such as screwing, etc., easy to operate.

[0085] The selection and design of the elastic material can reduce the wear caused by hard collision, and the ability of elastic deformation also means that it can maintain good sealing performance after multiple disassembly and assembly, thereby indirectly prolonging the service life of the sealing element 3.

[0086] Optionally, referring to Figure 3 As shown, the flow channel mouth part 1 includes a part body 11 and a first pressing edge 12, the inside of the part body 11 is formed with a first flow channel 10, and the first pressing edge 12 is arranged on the part body 11 and arranged on the circumferential direction of one end of the first flow channel 10, and the first pressing edge 12 is used for pressing the first elastic flange in the first direction A.

[0087] In this embodiment, the above-mentioned first pressing edge 12 can be configured as a rigid structure, and the first pressing edge 12 arranged on the circumferential direction of one end of the first flow channel 10 can uniformly apply force to the first elastic flange, thereby avoiding the problem of excessive local stress, preventing permanent deformation or damage of the first elastic flange due to excessive compression in the local part, and prolonging the service life of the sealing element 3. In addition, the first pressing edge 12 is specially designed to match the first elastic flange, which not only simplifies the installation process (only needs to apply appropriate pressure in the first direction A), but also ensures the consistency and accuracy of each installation, and reduces the error caused by human factors.

[0088] Optionally, referring to Figure 3 As shown, the flow channel piece 2 includes a flow channel piece body 21 and a second pressing edge 22, the inside of the flow channel piece body 21 is formed with a second flow channel 20, and the second pressing edge 22 is arranged on the flow channel piece body 21 and arranged on the circumferential direction of one end of the second flow channel 20, and the second pressing edge 22 is used for pressing the second elastic flange in the first direction A.

[0089] In this embodiment, the above-mentioned second pressing edge 22 can be configured as a rigid structure, and the second pressing edge 22 arranged on the circumferential direction of one end of the second flow channel 20 can uniformly apply force to the second elastic flange, thereby avoiding the problem of excessive local stress, preventing permanent deformation or damage of the first elastic flange due to excessive compression in the local part, and prolonging the service life of the sealing element 3. In addition, the second pressing edge 22 is specially designed to match the second elastic flange, which not only simplifies the installation process (only needs to apply appropriate pressure in the first direction A), but also ensures the consistency and accuracy of each installation, and reduces the error caused by human factors.

[0090] In another embodiment, referring to 8 to Figure 10As shown, the sealing member 3 further comprises a third sealing portion 34, which is arranged on the sealing member body 31 and used for sealingly connecting with the external member.

[0091] That is, in this embodiment, when the sealing member 3 is arranged on the external member, the sealing performance between the sealing member 3 and the external member needs to be ensured, and the third sealing portion 34 can effectively realize the sealing between the sealing member 3 and the external member.

That is, through the form of sealing clamping, while reducing the number of components, the sealing connection between the sealing member 3 and the external member can also be realized.

[0093] Taking the application of the flow channel assembly to the vehicle as an example, referring to Figures 8 to 10 As shown, the front compartment cover 4 comprises a front compartment outer panel 41 and a front compartment inner panel 42, which are connected with each other and define a cover cavity 40; the front compartment outer panel 41 is formed with an outer panel opening 410, the flow channel port component 1 is arranged in the cover cavity 40 through the outer panel opening 410, and the flow channel port component 1 is sealingly connected with the outer panel opening 410; the front compartment inner panel 42 is formed with an inner panel opening 420, the sealing member 3 is arranged in the inner panel opening 420 and sealingly connected therewith, and the sealing member 3 is sealingly connected with the flow channel port component 1.

[0095] In one embodiment, the outer wall of the sealing member 3 is provided with the third sealing portion 34 described above, which is recessed on the outer wall of the sealing member body 31 in the circumferential direction to form a clamping groove, which is used for interference clamping with the inner edge of the inner panel opening 420 to realize the sealing.
