Description

Technical Field

[0001] This application relates to the field of vehicle chassis technology, and in particular to an exhaust catalytic converter and a vehicle. Background Technology

[0002] The exhaust catalytic converter is an important purification device in the vehicle exhaust system. It can convert harmful gases such as carbon monoxide, hydrocarbons and nitrogen oxides in engine exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction.

[0003] Currently, taking the exhaust catalytic converter's outlet end as an example, a flange is typically installed at the end of the catalytic converter to connect to the exhaust pipe, and a bracket is also installed on the catalytic converter to connect it to the vehicle. This traditional design results in a large number of catalytic converter components and a heavy weight, which is not conducive to reducing the overall vehicle cost or to the lightweight design of the vehicle. Utility Model Content

[0004] In view of this, this application aims to propose an exhaust catalyst that helps reduce the overall vehicle cost and facilitates the lightweight design of the vehicle.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: An exhaust catalyst is provided in a vehicle and includes a catalyst body and a flange support located at one end of the catalyst body. The flange bracket is integrally formed and has an annular flange portion and a bracket portion connected to the flange portion; The flange is fixed to the end of the catalyst body, and the flange is provided with a first connection part for connecting to the exhaust pipe. The bracket is provided with a second connection part for connecting the exhaust catalyst to the vehicle.

[0006] Furthermore, the flange bracket is formed by stamping.

[0007] Furthermore, the inner edge of the flange protrudes towards the catalyst body, and a groove is formed on the side of the flange opposite to the catalyst body.

[0008] Furthermore, a flange is provided at the outer edge of the flange portion, the flange is folded toward the catalyst body side, and the support portion is connected to the flange.

[0009] Furthermore, the support portion includes a transition plate connected to the flange, and a support main board connected to the transition plate; The transition plate has a curvature that conforms to the flange. One end of the main support plate is connected to the transition plate, and the other end of the main support plate is provided with the second connecting part.

[0010] Furthermore, the main board of the bracket is provided with a through-hole for weight reduction, and / or the edge of the main board of the bracket is provided with a weight reduction groove.

[0011] Furthermore, the second connecting part includes a connecting plate connected to the main board of the bracket via a rubber block, and the connecting plate is provided with connecting holes.

[0012] Furthermore, the rubber block is embedded with an elastic element, which is connected to the connecting plate and the main support plate respectively.

[0013] Furthermore, the elastic element is formed from a plate made of spring steel, and both ends of the elastic element are connected to the main support plate, while the middle part of the elastic element arches out toward the connecting plate and is connected to the connecting plate.

[0014] Compared with related technologies, this application has the following advantages: (1) The exhaust catalyst described in this application, by integrally forming a flange bracket including a flange portion and a bracket portion, can reduce the number of parts in the exhaust catalyst by utilizing the first connecting portion on the flange portion and the second connecting portion on the bracket portion to realize the corresponding functions of the flange and the bracket respectively, thereby helping to reduce the material used in the bracket, reducing the manufacturing cost of the exhaust catalyst, and reducing the weight of the exhaust catalyst, thereby helping to reduce the overall vehicle cost and facilitating the lightweight design of the vehicle.

[0015] (2) The flange bracket is formed by stamping, which facilitates the manufacturing of the flange bracket, reduces the manufacturing cost of the flange bracket, and the stamping forming technology is mature, which also helps to ensure the structural quality of the flange bracket.

[0016] (3) By making the inner edge of the flange protrude toward the catalyst body and thereby forming a groove on the flange, the structural strength of the inner edge of the flange can be increased, which helps to increase the reliability of the connection between the flange and the catalyst body.

[0017] (4) By setting a flange on the outer edge of the flange, the structural strength of the flange itself can be increased by using the flange structure, and the support part can be connected to the flange, which also facilitates the manufacturing of the flange support by stamping.

[0018] (5) The bracket part includes a transition plate connected to the flange and a connecting plate connected to the transition plate, and the transition plate has a bending arc that conforms to the flange. This not only facilitates the stamping of the flange bracket but also helps to ensure the connection strength between the bracket part and the flange part, thus ensuring the overall quality of the flange bracket.

[0019] (6) By setting weight reduction holes or weight reduction grooves on the connecting plate, the weight of the connecting plate can be reduced, which is conducive to the lightweight design of the flange bracket.

[0020] (7) The second connection part includes a connection plate connected to the main board of the bracket by a rubber block, and a connection hole is provided on the connection plate. While connecting the exhaust catalyst to the vehicle, the vibration damping characteristics of the rubber block can be used to reduce the vibration transmission between the vehicle body and the exhaust catalyst, that is, between the vehicle body and the exhaust system, which helps to improve the NVH performance of the whole vehicle.

[0021] (8) By embedding elastic elements in the rubber block and connecting the elastic elements with the main board of the bracket and the connecting plate, the elastic elements can not only improve the shortcomings of the rubber block in meeting the vibration isolation and buffering requirements of different vibration frequency bands, but also achieve effective isolation and buffering of vibrations of different frequencies through the synergy of the rubber block and the elastic elements. At the same time, it can ensure that the connection between the flange bracket and the connection point in the vehicle will not be broken when the rubber block breaks and fails, which helps to improve the safety of the exhaust catalyst and the overall exhaust system in the vehicle.

[0022] (9) The elastic element is made of spring steel, and its two ends are connected to the main board of the bracket, while the middle part is arched towards the connecting plate and connected to the connecting plate. This facilitates the connection between the elastic element and the main board of the bracket and the connecting plate, and also ensures the reliability of the connection between the elastic element and the main board of the bracket and the connecting plate while ensuring the elastic deformation performance of the elastic element.

[0023] Another object of this application is to provide a vehicle equipped with an exhaust catalytic converter as described above.

[0024] The vehicle described in this application has the same advantages as the aforementioned exhaust catalytic converter compared to related technologies, and will not be repeated here. Attached Figure Description

[0026] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0030] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0032] An embodiment of the first aspect of this application provides an exhaust catalyst installed in a vehicle, and the exhaust catalyst of this embodiment, through its innovative design of the upper flange and bracket, helps to reduce the overall vehicle cost and facilitates the lightweight design of the vehicle.

[0033] In related technologies, in order to connect the exhaust catalyst to the exhaust pipe and to connect the exhaust catalyst to the vehicle, a flange structure and a bracket structure are usually provided on the exhaust catalyst.

[0034] Taking the exhaust catalytic converter's outlet end as an example, a flange is typically installed at the end of the catalytic converter. This flange is welded to the port of the exhaust catalytic converter's outlet end to connect it to the exhaust pipe. Simultaneously, a bracket is generally fixed to the exhaust catalytic converter's housing by welding and connected to the engine or vehicle body via conventional connection methods such as screws, thus connecting the exhaust catalytic converter to the vehicle.

[0035] Currently, the flanges and brackets on exhaust catalysts are manufactured separately and installed on the catalysts. This traditional design results in a large number of parts and a heavy weight for the exhaust catalysts, which is not conducive to reducing the overall vehicle manufacturing cost and also not conducive to achieving lightweight design of the vehicle.

[0036] In view of this, in order to overcome the shortcomings of related technologies, the exhaust catalyst of this embodiment combines... Figures 1 to 4 As shown, the overall design includes a catalyst body 1 and a flange support 2 located at one end of the catalyst body 1.

[0037] The flange bracket 2 is integrally formed and has an annular flange portion 201 and a bracket portion 202 connected to the flange portion 201. The flange portion 201 is fixed to the end of the catalyst body 1, and the flange portion 201 is provided with a first connecting portion for connecting to the exhaust pipe. The bracket portion 202 is provided with a second connecting portion for connecting the exhaust catalyst to the vehicle.

[0038] Therefore, as described above, by integrally forming the flange bracket 2 including the flange portion 201 and the bracket portion 202, this embodiment can reduce the number of parts in the exhaust catalyst by utilizing the first connecting portion on the flange portion 201 and the second connecting portion on the bracket portion 202 to realize the corresponding functions of the flange and the bracket, thereby helping to reduce the material used in the bracket structure, reducing the manufacturing cost of the exhaust catalyst, and reducing the weight of the exhaust catalyst, thus achieving the effect of reducing the overall vehicle cost and facilitating the lightweight design of the vehicle.

[0039] Based on the above general introduction, it is worth noting that the catalyst body 1 of this embodiment has the same structure as the catalyst in the existing vehicle exhaust system, and can be referred to as an existing exhaust catalyst in the vehicle.

[0040] Furthermore, structurally, the catalyst body 1 generally has an inlet cone 101 and an outlet cone 102. A connecting pipe 103 can be connected to the outlet cone 102. Sensor mounting bases 104 are also provided on the inlet cone 101 and the connecting pipe 103 for installing sensors at the inlet and outlet ends of the catalyst body 1, respectively. These sensors typically include oxygen sensors and nitrogen oxide sensors, etc.

[0041] Continue as Figure 1 and Figure 2 As shown in the figure, in some exemplary embodiments, the flange bracket 2 with flange portion 201 and bracket portion 202 is connected to the outlet end of the exhaust catalyst, and the flange portion 201 in the flange bracket 2 is specifically fixed to the end of the connecting pipe 103. At the same time, this embodiment will also be described with the flange bracket 2 set at the outlet end of the exhaust catalyst as an example.

[0042] Of course, it should be noted that in specific implementations, besides positioning the flange bracket 2 at the outlet end of the exhaust catalyst, it is also possible to position the flange bracket 2 at the inlet end of the exhaust catalyst in other feasible implementations. Furthermore, when the flange bracket 2 is located at the inlet end of the exhaust catalyst, the connection arrangement of the flange bracket 2 on the catalyst body 1 can refer to the arrangement of the flange bracket 2 at the outlet end of the exhaust catalyst, and will not be elaborated further here.

[0043] In this embodiment, we continue to combine Figures 1 to 3As shown, in some of the exemplary embodiments, the flange bracket 2 may be stamped, for example.

[0044] In this way, by making the flange bracket 2 by stamping, the manufacturing of the flange bracket 2 can be facilitated, the manufacturing cost of the flange bracket 2 can be reduced, and the stamping forming technology is mature, which also helps to ensure the structural quality of the flange bracket 2.

[0045] However, besides stamping, in other implementations, the flange bracket 2 can also be manufactured as a single piece using methods such as casting or machining. But considering both manufacturing convenience and cost, stamping is still the preferred method for manufacturing the flange bracket 2.

[0046] Taking the flange bracket 2 manufactured by stamping as an example, this embodiment continues to combine... Figure 3 and Figure 4 As shown, the flange portion 201 has a flange 2011 in its structure. The flange 2011 serves as the main structure of the flange portion 201. Its inner edge is connected to the connecting pipe 103. In some exemplary embodiments, for example, a protrusion towards the catalyst body 1 may be provided at the inner edge of the flange portion 201, thereby forming a sink 2013 on the side of the flange portion 201 opposite to the catalyst body 1.

[0047] At this time, by making the inner edge of the flange 2011 in the flange portion 201 protrude toward the catalyst body 1, and thereby forming a groove 2013 on the flange 2011, it can be understood that the groove 2013 protruding toward the catalyst body 1 can have a reinforcing effect similar to a reinforcing rib, thereby increasing the structural strength at the inner edge of the flange 2011, which helps to increase the reliability of the connection between the flange portion 201 and the connecting pipe 103 in the catalyst body 1.

[0048] It is worth noting that, in practical implementation, the flange 201 and the catalyst body 1, that is, the flange 2011 and the connecting pipe 103, can usually be fixed together by welding. This allows the flange 201 to be welded to the catalyst body 1, which is not only simple in process and operation, but also ensures the reliability of the connection between the flange 201 and the catalyst body 1, as well as the sealing of the connection point, preventing leakage problems after the exhaust catalyst is connected to the exhaust pipe.

[0049] In this embodiment, taking the flange bracket 2 formed by stamping as an example, in some exemplary embodiments, a flange 2012 may also be provided at the outer edge of the flange portion 201. The flange 2012 is folded toward the catalyst body 1 and is arranged in a circle around the flange 2011. The bracket portion 202 is also specifically connected to the flange 2012.

[0050] At this point, by providing a flange 2012 on the outer edge of the flange portion 201, it can be understood that the flange structure can be used to increase the structural strength of the flange portion 201 itself based on the stamping of the flange bracket 2, which helps to improve the stability of the connection between the exhaust catalyst and the exhaust pipe. At the same time, by connecting the bracket portion 202 to the flange 201 on the outer edge of the flange portion 201, it is obviously also convenient to manufacture the flange bracket 2 by stamping, which can reduce the design and manufacturing cost of the flange bracket 2.

[0051] In this embodiment, it should be noted that the flange portion 201 with flange 2011 and flange 2012 can be generally of a ring-shaped structure. Furthermore, in specific implementations, the flange 2011 in the flange portion 201 can be, for example, as shown in the example... Figure 3 and Figure 4 The structure shown is roughly elliptical. Since the flange 201 is generally elliptical, the first connecting portion located on the flange 201 can be, for example, a connecting through hole 2014 provided on the flange 201. Furthermore, two connecting through holes 2014 can be provided, and the two connecting through holes 2014 are located along the major axis of the elliptical flange 2011.

[0052] Therefore, the first connection part used for connecting the flange 201 and the exhaust pipe adopts a connection through hole 2014, which obviously has the advantages of simple structure and easy design and molding. Moreover, in specific implementation, further reference is made. Figure 1 and Figure 2 As shown, the connection between the flange 201 and the exhaust pipe can generally be achieved by connecting bolts 3 that pass through the connection hole 2014.

[0053] The flange 201 is connected to the exhaust pipe via connecting bolts 3, and the structure can be referenced from the relevant structure in existing vehicle exhaust systems. Specifically, a flange structure with a similar shape to the flange 201 is usually provided at the end of the exhaust pipe that connects to the flange 201. During connection, the flange 201 and the flange structure at the end of the exhaust pipe are mated together. Then, the connecting bolts 3 pass through the flange 201 and the flange structure at the end of the exhaust pipe, and are screwed together with the corresponding nuts.

[0054] In this embodiment, taking the flange bracket 2 formed by stamping as an example, in some exemplary embodiments, the bracket portion 202 in the flange bracket 2 may include, for example, a transition plate 2021 connected to the flange 2012, and a bracket main plate 2022 connected to the transition plate 2021.

[0055] See also Figure 3 and Figure 4 As shown, given that the flange 2011 in the flange portion 201 is generally elliptical (or may be circular), and the flange 2012 is arranged around the outer edge of the flange 2011, the aforementioned transition plate 2021 has a curvature conforming to the flange 2012 so as to connect with the edge of the flange 2012. Furthermore, one end of the aforementioned support main plate 2022 is connected to the transition plate 2021, and a second connecting portion is provided at the other end of the support main plate 2022.

[0056] It is understandable that by including a transition plate 2021 connected to the flange 2012 in the flange 201 in the bracket portion 202, and a bracket main plate 2022 connected to the transition plate 2021, and by making the transition plate 2021 have a curvature conforming to the flange 2012, it is possible to achieve the connection between the bracket portion 202 and the flange portion 201, which not only facilitates the stamping and forming of the flange bracket 2, but also helps to ensure the connection strength between the bracket portion 202 and the flange portion 201, thus ensuring the overall quality of use of the flange bracket 2.

[0057] In this embodiment, it is worth noting that the structure of the bracket main board 2022 in the bracket part 202 is not limited in the specific implementation. Those skilled in the art can design it according to the layout requirements of the exhaust system in a specific vehicle model, as long as the bracket main board 2022 can reliably connect the exhaust catalyst to the vehicle through its second connecting part.

[0058] Specifically, as an example of the bracket motherboard 2022 structure, it is still as follows: Figure 3 and Figure 4 As shown, it may include, for example, a first plate 20221, a second plate 20222, and a third plate 20223 connected in sequence.

[0059] One end of the first plate 20221 is connected to the flange 2012 in the flange portion 201, and the other end of the first plate 20221 is connected to the second plate 20222. The first plate 20221 is arranged radially along the flange portion 201. The side of the second plate 20222 is connected to the first plate 20221, and there is a certain angle between the second plate 20222 and the first plate 20221. This angle mainly meets the installation angle requirements of the exhaust catalyst connection point in the vehicle. The third plate 20223 is also connected to one end of the second plate 20222 on its side, and the aforementioned second connecting part is provided on the third plate 20223.

[0060] In this embodiment, since the bracket portion 202 is a stamped part, in some exemplary embodiments, a through-hole weight-reduction hole 2023 may be provided on the bracket main plate 2022. In this way, by providing the weight-reduction hole 2023 on the bracket main plate 2022, the weight of the bracket main plate 2022 can be reduced, which is beneficial to the lightweight design of the flange bracket 2.

[0061] In addition, in some exemplary embodiments of this example, a weight-reduction groove 2024 may be provided on the edge of the bracket motherboard 2022. In this case, by providing the weight-reduction groove 2024 on the bracket motherboard 2022, the weight of the bracket motherboard 2022 can also be reduced, which is beneficial to achieving a lightweight design of the flange bracket 2.

[0062] In practice, it will still be based on Figure 3 and Figure 4 As shown, the bracket mainboard 2022 includes a first plate 20221, a second plate 20222, and a third plate 20223 connected in sequence. For example, the weight-reducing holes 2023 can be located on the first plate 20221, and the weight-reducing grooves 2024 can be located on the third plate 20223. Thus, by providing weight-reducing holes 2023 on the first plate 20221 and weight-reducing grooves 2024 on the third plate 20223, a weight-reducing effect can be achieved while maintaining the structural strength of the bracket mainboard 2022 itself.

[0063] In this embodiment, in some exemplary implementations, the second connecting portion located on the bracket portion 202 may be, for example, a connecting hole 206 provided on the bracket motherboard 2022.

[0064] At this point, taking the bracket main board 2022, which includes a first plate 20221, a second plate 20222, and a third plate 20223 connected in sequence, as an example, the connection hole 206 is specifically located on the third plate 20223. In addition, the connection holes 206 can generally be set near both ends of the third plate 20223, so that by designing multiple connection positions, the stability of the exhaust catalyst connection in the vehicle can be guaranteed.

[0065] In practice, the connection between the bracket 202 and the connection point in the vehicle is generally achieved by bolts passing through the connection hole 206. The connection point in the vehicle is located on the engine or at the bottom of the vehicle body, and the bracket 202 is connected to the connection point in the vehicle using a screw-on structure. Obviously, this method has the advantages of simple structure, convenient operation, and ensuring connection stability.

[0066] Besides allowing the second connecting portion on the bracket portion 202 to be a connecting hole 206 provided on the bracket main board 2022, it is worth noting that in some other exemplary embodiments, combined with Figure 5 As shown, in this embodiment, for example, the second connecting part may include a connecting plate 204 connected to the bracket main board 2022 by a rubber block 203, and a connecting hole 206 is provided on the connecting plate 204.

[0067] In the case where the connecting plate 204 connected by the rubber block 203 is used in the second connection part, taking the bracket main board 2022, which includes the first plate 20221, the second plate 20222 and the third plate 20223 connected in sequence, as an example, the connecting plate 204 can be connected to the third plate 20223 in the bracket main board 2022 by the rubber block 203. At this time, the structure of the third plate 20223 can be adaptively adjusted so as to achieve connection with the rubber block 203, while avoiding the third plate 20223 having too many parts, which would waste materials and be detrimental to the overall weight reduction of the flange bracket 2.

[0068] It is understandable that by including a connecting plate 204 connected to the main board 2022 of the bracket via a rubber block 203 in the second connecting part, and providing a connecting hole 206 on the connecting plate 204, it is possible to reduce the vibration transmission between the vehicle body (or engine) and the exhaust catalyst, i.e., between the vehicle body and the exhaust system, by utilizing the vibration damping characteristics of the rubber block 203 while connecting the exhaust catalyst to the vehicle, thereby helping to improve the NVH performance of the whole vehicle.

[0069] In practical implementation, the aforementioned rubber block 203 can be made of conventional EPDM rubber or other rubber materials with good structural properties and excellent weather resistance. Meanwhile, in this embodiment, both the flange bracket 2 and the connecting plate 204 can be stamped sheet metal parts, and the rubber block 203 and the bracket main plate 2022, as well as the rubber block 203 and the connecting plate 204, can be fixed together by vulcanization.

[0070] Based on the fact that the second connecting part includes a connecting plate 204 connected to the bracket main board 2022 via a rubber block 203, in some exemplary embodiments of this embodiment, for example, an elastic element 205 may also be embedded in the rubber block 203, and the elastic element 205 may be connected to the connecting plate 204 and the third plate 20223 in the bracket main board 2022 respectively.

[0071] At this point, by embedding an elastic element 205 within the rubber block 203 and connecting the elastic element 205 to the main support plate 2022 and the connecting plate 205, it can be understood that this not only addresses the inadequacy of the rubber block 203 in simultaneously meeting the vibration isolation and buffering requirements of different vibration frequency bands, but also achieves effective isolation and buffering of vibrations at different frequencies through the synergy between the rubber block 203 and the elastic element 205. Simultaneously, it ensures that the connection between the flange bracket 2 and the connection point in the vehicle remains intact even if the rubber block 203 breaks, thus contributing to improved safety of the exhaust catalytic converter and the overall exhaust system within the vehicle.

[0072] In specific implementations, for the elastic element 205 embedded inside the rubber block 203, in some exemplary embodiments, it is combined with... Figure 6 As shown, the elastic member 205 can be formed from a plate made of spring steel, and both ends of the elastic member 205 are connected to the main support plate 2022, while the middle part of the elastic member 205 arches out toward the connecting plate 204 and is connected to the connecting plate 204.

[0073] This design allows the elastic element 205 to be made of spring steel, with both ends connected to the main support plate 2022 and the middle part arching towards and connected to the connecting plate 204. This facilitates the connection between the elastic element 205 and the main support plate 2022 and the connecting plate 204, while also ensuring the reliability of the connection between the elastic element 205 and the main support plate 2022 while maintaining its elastic deformation performance.

[0074] It should be noted that, in specific implementation, the width of the elastic element 205 made of spring steel is generally smaller than that of the third plate 20223 and the connecting plate 204 connected to it. Furthermore, during manufacturing, the elastic element 205 can be welded to the main support plate 2022 and the connecting plate 204, and then they are placed in a mold to form a rubber block 203 that wraps around the elastic element 205 and connects the main support plate 2022 and the connecting plate 204.

[0075] It is worth noting that, regarding the exhaust catalyst of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, reference is still made to... Figures 1 to 4 As shown, it may include, for example, a catalyst body 1 and a flange support 2 located at the gas outlet end of the catalyst body 1.

[0076] The flange bracket 2 is integrally stamped and has an annular flange portion 201 and a bracket portion 202 connected to the flange portion 201. The flange portion 201 is fixed to the end of the connecting pipe 103 in the catalyst body 1, and the flange portion 201 includes a flange 2011 and a flange 2012 located on the outer edge of the flange 2011. The flange 2011 also has a connection hole 2014 for connecting to the exhaust pipe. The bracket portion 202 includes a transition plate 2021 connected to the flange 2012 and a bracket main plate 2022 connected to the transition plate 2021. The bracket main plate 2022 has a connection hole 206 for connecting the exhaust catalyst to the vehicle.
