[0002] Currently, flanges are commonly used to connect the catalyst pack and the pipeline. This connection requires multiple bolts and nuts to prevent relative movement between the catalyst pack and the pipeline along the pipeline's length. However, this method involves cumbersome bolt tightening, making the installation process complex and hindering disassembly after installation, thus affecting the connection efficiency. Summary of the Invention

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0035] Some embodiments of this application provide a connection component, such as... Figures 1 to 3 As shown, the connection assembly 10 includes a first connecting element 11 and a second connecting element 12. The first connecting element 11 is used to connect the catalyst 20, and the second connecting element 12 is used to connect the pipe 30. After the first connecting element 11 and the second connecting element 12 are connected, the catalyst 20 and the pipe 30 can be relatively fixed, thereby realizing the transmission of gas inside the catalyst 20 and the pipe 30.
[0036] In one implementation, the pipe 30 can be located at the intake end of the catalytic converter 20, thereby allowing the gas in the pipe 30 to be transported into the catalytic converter 20 for catalytic action. In another implementation, the pipe 30 can be located at the exhaust end of the catalytic converter 20, thereby allowing the gas catalyzed by the catalytic converter 20 to be discharged through the pipe 30.
[0037] One of the first connecting element 11 and the second connecting element 12 has a slot 110, and the other includes a plug 122. The plug 122 is inserted into the slot 110 to connect the catalyst 20 and the pipe 30 in the first direction X, and to restrict the relative movement of the first connecting element 11 and the second connecting element 12 in the first direction X.
[0038] Therefore, for the connecting assembly 10 provided in this application embodiment, after the plug-in 122 is inserted into the slot 110, the catalyst 20 and the pipeline 30 are internally connected. Simultaneously, since the movement of the first connecting element 11 and the second connecting element 12 in the first direction X is restricted, stable gas delivery inside the catalyst 20 and the pipeline 30 can be ensured. On the other hand, since the first connecting element 11 and the second connecting element 12 are connected by plugging, during the disassembly and assembly of the catalyst 20 and the pipeline 30, it is only necessary to remove or insert the plug-in 122 from the slot 110 to complete the disassembly or assembly of the catalyst 20 and the pipeline 30. The above disassembly and assembly method can achieve high efficiency in disassembly and assembly of the catalyst 20 and the pipeline 30.
[0039] In some examples, the first connecting element 11 has a slot 110, and the second connecting element 12 includes a connector 122. In this case, by inserting the connector 122 of the second connecting element 12 into the slot 110 of the first connecting element 11, the movement of the first connecting element 11 and the second connecting element 12 in the first direction X can be restricted, thereby ensuring stable gas delivery inside the catalyst 20 and the pipeline 30.
[0040] In other examples, the first connecting element 11 includes a plug 122, and the second connecting element 12 has a slot 110. In this case, by inserting the plug 122 of the first connecting element 11 into the slot 110 of the second connecting element 12, the movement of the first connecting element 11 and the second connecting element 12 in the first direction X can be restricted, thereby ensuring stable gas delivery inside the catalyst 20 and the pipeline 30.
[0041] In some examples, the thickness of the connector 122 is equal to the opening width of the slot 110, so that after the connector 122 is inserted into the slot 110, the two opposite sidewalls in the slot 110 can restrict the movement of the connector 122 along the first direction X.
[0042] In other examples, the connector 122 and the slot 110 can be connected by an interference fit. In this case, the thickness of the connector 122 is larger than the opening width of the slot 110. Therefore, when assembling the first connecting element 11 and the second connecting element 12, a certain force needs to be applied to insert the connector 122 into the slot 110. After the first connecting element 11 and the second connecting element 12 are assembled, relative rotation between the first connecting element 11 and the second connecting element 12 is difficult, thereby achieving relative fixation between the catalyst 20 and the pipe 30 and improving the overall connection stability.
[0043] In one implementation, the first connecting element 11 and the catalyst 20 can be integrally formed. This can ensure the stability of the connection between the two and the airtightness between the catalyst 20 and the first connecting element 11, so as to avoid the problem of air leakage caused by the opening of the connection interface between the catalyst 20 and the first connecting element 11.
[0044] In addition, the second connecting element 12 and the pipe 30 can be integrally formed, which can ensure the stability of the connection between the two and the airtightness between the pipe 30 and the second connecting element 12, so as to avoid the problem of air leakage caused by the opening of the connection interface between the pipe 30 and the second connecting element 12.
[0045] For ease of explanation, the following embodiments of this application illustrate the example of a first connecting element 11 having a slot 110 and a second connecting element 12 including a plug 122.
[0046] In some embodiments, such as Figures 1 to 3 As shown, the first connecting element 11 includes a first main body 111 with a slot 110 and a plug 112 connected to the first main body 111. The second connecting element 12 includes a second main body 121 with a mating groove 120 and a plug 122 connected to the second main body 121. The plug 112 is inserted into the mating groove 120.
[0047] In this case, the connector 112 is inserted into the mating groove 120, which can further enhance the connection stability between the first connecting element 11 and the second connecting element 12, thereby improving the gas delivery stability inside the catalyst 20 and the pipeline 30.
[0048] In some examples, the first main body 111 and the connector 112 can be integrally formed, which can ensure the connection stability of the two, thereby ensuring the structural stability of the first connecting element 11.
[0049] In some examples, the second main body 121 and the connector 122 can be integrally formed, which can ensure the structural stability of the second connecting element 12.
[0050] In some embodiments, such as Figures 2 to 4 As shown, at least one end of the first main body portion 111 in its extending direction abuts against the second main body portion 121.
[0051] As an example, the first body portion 111 includes a first end portion 1111 located at one end in its extending direction. After the connector 122 is inserted into the slot 110, the first end portion 1111 abuts against the second body portion 121, so that the user can know that the first connecting element 11 and the second connecting element 12 have been assembled, thereby ensuring the alignment and effective communication between the catalyst 20 and the pipe 30.
[0052] In some embodiments, such as Figures 2 to 4 As shown, at least one end of the second main body portion 121 in its extending direction abuts against the first main body portion 111.
[0053] As an example, the second body portion 121 includes a third end portion 1211 located at one end in its extending direction. After the connector 122 is inserted into the slot 110, the third end portion 1211 abuts against the first body portion 111, so that the user can know that the first connecting element 11 and the second connecting element 12 have been assembled, thereby ensuring the alignment and effective communication between the catalyst 20 and the pipe 30.
[0054] In some embodiments, such as Figures 2 to 4 As shown, the two ends of the first main body 111 in its extension direction respectively abut against the two ends of the second main body 121 in its extension direction.
[0055] As an example, the first main body 111 includes a first end 1111 and a second end 1112 located at both ends of its extension direction, and the second main body 121 includes a third end 1211 and a fourth end 1212 located at both ends of its extension direction. After the connector 122 is inserted into the slot 110 and the connector 112 is inserted into the mating groove 120, the first end 1111 abuts against the third end 1211, and the second end 1112 abuts against the fourth end 1212. This allows the user to know that the first connecting element 11 and the second connecting element 12 have been assembled, thereby ensuring the alignment and effective communication between the catalyst 20 and the pipe 30; on the other hand, it also improves the assembly stability of the first connecting element 11 and the second connecting element 12.
[0056] In some embodiments, such as Figures 2 to 4 As shown, the edge of at least one end of the first main body portion 111 in its extending direction is flush with the edge of the corresponding end of the second main body portion 121.
[0057] In this case, since the end edges of the first main body 111 and the end edges of the second main body 121 are flush, the flatness of the connecting assembly 10 can be improved and the gap between the first connecting element 11 and the second connecting element 12 can be reduced. This improves the overall aesthetics and also helps to improve the airtightness of the connecting assembly 10, so as to avoid the problem of gas leakage between the catalyst 20 and the pipeline 30.
[0058] As an example, the first end 1111 of the first main body 111 abuts against the third end 1211 of the second main body 121, and the edge of the first end 1111 is flush with the edge of the third end 1211. That is, the edge of the first end 1111 and the edge of the third end 1211 face each other and are flush with each other.
[0059] As another example, the second end 1112 of the first main body portion 111 abuts against the fourth end 1212 of the second main body portion 121, and the edge of the second end 1112 is flush with the edge of the fourth end 1212. That is, the edge of the second end 1112 is directly opposite the edge of the fourth end 1212, and thus they are flush with each other.
[0060] In some examples, the edge of the first end 1111 is flush with the edge of the third end 1211, and the edge of the second end 1112 is flush with the edge of the fourth end 1212.
[0061] In some embodiments, such as Figure 2 and Figure 5 As shown, the first surface 1121 of the connector 112 away from the catalyst 20 and the first bottom surface 1101 of the slot 110 near the catalyst 20 are located on the same plane (e.g., the first plane).
[0062] With this configuration, during the installation of the first connecting element 11 and the second connecting element 12, the plug 122 can be placed against the first surface 1121 and inserted into the slot 110, thereby improving the assembly efficiency of the first connecting element 11 and the second connecting element 12.
[0063] In some embodiments, such as Figure 3 and Figure 5 As shown, the second surface 1221 of the connector 122 on the side away from the pipe 30 and the second bottom surface 1201 of the mating groove 120 on the side near the pipe 30 are located on the same plane (e.g., the second plane).
[0064] With this configuration, during the installation of the first connecting element 11 and the second connecting element 12, the connector 112 can be placed against the second surface 1221 and inserted into the mating groove 120, which helps to improve the assembly efficiency of the first connecting element 11 and the second connecting element 12.
[0065] In some examples, after the connector 122 is inserted into the slot 110 and the connector 112 is inserted into the mating groove 120, the first plane and the second plane can come into contact with each other.
[0066] In some examples, the first surface 1121 is semi-annular, and the first bottom surface 1101 is semi-annular. For example, the inner edge of the first surface 1121 and the inner edge of the first bottom surface 1101 can be connected to form a circle. The diameter of this circle is the same as the inner diameter of the catalyst 20 at the location of the first connecting element 11, thus ensuring that the gas is not obstructed when passing through the location of the first connecting element 11.
[0067] In some examples, the inner edge of the second surface 1221 and the inner edge of the second bottom surface 1201 can be connected to form a circle. The diameter of this circle is the same as the inner diameter of the pipe 30 at the location of the second connecting element 12, thus ensuring that the gas is not obstructed when passing through the location of the second connecting element 12.
[0068] In some embodiments, such as Figure 2 and Figure 5As shown, a first sealing groove 1001 is formed on the first surface 1121, and a second sealing groove 1002 is formed on the first bottom surface 1101. The first sealing groove 1001 and the second sealing groove 1002 are connected end to end. Since the first surface 1121 and the first bottom surface 1101 are located on the same plane, this facilitates the opening and connection of the first sealing groove 1001 and the second sealing groove 1002.
[0069] Based on this, the connecting assembly 10 also includes a seal 40, which is disposed in the first sealing groove 1001 and the second sealing groove 1002. This allows for the installation of the seal 40. Furthermore, after the first connecting element 11 and the second connecting element 12 are inserted, the seal 40 can contact the second connecting element 12, thereby sealing the gap between the first connecting element 11 and the second connecting element 12 and preventing gas leakage from the gap between them.
[0070] In some examples, the first sealing groove 1001 is close to the inner edge of the first surface 1121, and the second sealing groove 1002 is close to the inner edge of the first bottom surface 1101.
[0071] In some embodiments, the material of the seal 40 includes copper. Copper is a high-purity copper material, typically with a copper content greater than 99.9%. Copper is characterized by its softness, high corrosion resistance, and low cost, enabling it to ensure good sealing between the first connecting element 11 and the second connecting element 12 while effectively reducing the cost of the connecting assembly 10.
[0072] In some embodiments, such as Figure 4 As shown, the connecting assembly 10 also includes a clamp 50, which is fitted onto the first connecting element 11 and the second connecting element 12 to prevent the plug 122 from disengaging from the slot 110.
[0073] By setting the clamp 50, the connection stability between the first connecting element 11 and the second connecting element 12 can be further improved.
[0074] As an example, clamp 50 is fitted onto the outer surfaces of the first main body portion 111 and the second main body portion 121, where the outer surface refers to the outermost surface of the first main body portion 111 and the second main body portion 121 relative to the axis of the pipe 30. After clamp 50 is fitted onto the first main body portion 111 and the second main body portion 121, the relative movement between the first main body portion 111 and the second main body portion 121 can be restricted, thereby ensuring the connection stability between the first connecting element 11 and the second connecting element 12.
[0075] When it is necessary to disassemble the first connecting element 11 and the second connecting element 12, simply remove the clamp 50 and then pull the first main body 111 and the second main body 121 in opposite directions to disengage the first connecting element 11 and the second connecting element 12.
[0076] In some examples, the clamp 50 can be selected from one of the following: elastic clamp, single-ear stepless clamp, worm clamp, etc., as long as it can achieve the locking between the first connecting element 11 and the second connecting element 12 and prevent them from loosening.
[0077] In some embodiments, the first connecting element 11 has a first mounting groove, and the second connecting element 12 has a second mounting groove. The first mounting groove and the second mounting groove are interconnected, and the clamp 50 is disposed within the first mounting groove and the second mounting groove. This effectively positions the clamp 50, avoiding difficulties in positioning and installing the clamp during installation due to the smooth surfaces of the first connecting element 11 and the second connecting element 12.
[0078] Understandably, since the first main body 111 and the second main body 121 have slots 110 and mating grooves 120 respectively on their respective sides facing each other, while the first mounting groove and the second mounting groove are located on the sides of the first main body 111 and the second main body 121 opposite to each other, the first mounting groove and the slot 110 can be set at different heights. This avoids the first main body 111 becoming weak due to the presence of the first mounting groove and the slot 110, thus preventing cracks or damage under the tightening action of the clamp. Similarly, the second mounting groove and the mating groove 120 can be set at different heights to ensure the structural stability of the second main body 121.
[0079] In some examples, the first main body 111 may have a larger thickness in its radial direction, so that the first mounting groove and slot 110 do not become weak after being opened, thereby ensuring the structural stability of the first main body 111. Similarly, the second main body 121 may also have a larger thickness in its radial direction to ensure the structural stability of the second main body 121.
[0080] Some embodiments of this application also provide an exhaust gas treatment device, such as... Figure 4 As shown, the exhaust gas treatment device 100 includes a catalyst 20, a pipe 30, and a connection assembly 10 as described in any of the above embodiments. The catalyst 20 is connected to a first connection element 11, and the pipe 30 is connected to a second connection element 12.
[0081] Since the exhaust gas treatment device 100 includes the connecting component 10, the technical effects of the connecting component 10 are not described in detail here.
[0082] In some examples, the catalyst 20 and the first connecting element 11 can be integrally formed, and the pipe 30 and the second connecting element 12 can be integrally formed.
[0083] In some embodiments, the exhaust gas treatment device further includes an engine exhaust pipe.
[0084] In some examples, pipe 30 can be connected between the engine exhaust pipe and the catalytic converter 20. In this case, pipe 30 is used to deliver the exhaust gas discharged from the engine exhaust pipe to the catalytic converter 20 for catalytic treatment of the exhaust gas, thereby purifying the exhaust gas.
[0085] In other examples, pipe 30 may be connected to the side of catalytic converter 20 away from the engine exhaust pipe, in which case pipe 30 is used to discharge exhaust gas purified by catalytic converter 20.
[0086] In some examples, catalyst 20 can be one of a three-way catalyst, an oxidation catalyst, a selective catalytic reduction catalyst, etc.
[0087] Some embodiments of this application also provide a vehicle that includes the exhaust gas treatment device described in any of the above embodiments.
[0088] Since the vehicle includes an exhaust gas treatment device with connecting components, the technical effects of including the aforementioned connecting components in the vehicle will not be elaborated here.
