Description

Technical Field

[0001] This application relates to the field of vehicle chassis technology, and in particular to an exhaust suspension and a vehicle equipped with it. Background Technology

[0002] In a vehicle, the exhaust system is one of the core components. When it is working, it will vibrate due to factors such as engine interference and exhaust airflow pulsation. When the vibration is transmitted to the vehicle body, it can easily cause resonance of the vehicle body and generate significant noise pollution.

[0003] To meet the high requirements of vehicles for NVH (Noise, Vibration, and Harshness) performance and ride comfort, existing vehicles typically use rubber blocks between the exhaust suspension and the vehicle body to buffer and isolate vibrations. However, existing exhaust suspensions have a single dynamic stiffness, resulting in low adaptability to load strength and hindering improvements in the reliability of the suspension structure and the overall quality of the exhaust suspension. Utility Model Content

[0004] In view of this, this application aims to provide an exhaust hanger to improve its performance.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: An exhaust venting hanger includes a hanger bracket and a rubber body fixedly connected to the hanger bracket; The suspension bracket is provided with a first connecting part for connecting to the vehicle body, and a deformable part formed by a part of the suspension bracket; the rubber body is provided with a second connecting part for connecting to the exhaust system. The deformation section is located above the rubber body, and the deformation section is adapted to elastically deform when the rubber body is subjected to an impact load greater than a set threshold.

[0006] Furthermore, the hanging bracket is formed from a plate made of spring steel, and the deformable part includes a curved structure formed by bending the hanging bracket itself; the curved structure consists of multiple connected in sequence, and the bending directions between adjacent curved structures are opposite, so that the deformable part extends in a corrugated shape.

[0007] Furthermore, the hanging bracket has a receiving space, the rubber body is located in the receiving space, and the hanging bracket forms a wrap around the bottom of the rubber body and at least two opposite sides.

[0008] Furthermore, the hanging bracket includes a U-shaped bracket body and connecting arms connected to both ends of the bracket body; the bracket body forms the receiving space, the rubber body is connected to the bracket body, and each of the connecting arms is provided with the first connecting part.

[0009] Furthermore, the support body includes two side walls arranged opposite to each other, and a bottom wall connecting the two side walls; each of the two side walls has a first part connected to the side of the rubber body, and a second part located above the first part; the second part on each side is connected to the connecting arm on the same side, and the deformation part is provided on the second part on each side.

[0010] Furthermore, the first connecting portion on each of the connecting arms is equipped with a connecting hole.

[0011] Furthermore, the second connecting portion includes a hook connection hole that extends through the rubber body.

[0012] Furthermore, the rubber body is provided with through-holes, and the buffer holes are a plurality of holes arranged circumferentially around the hook connection hole.

[0013] Furthermore, viewed axially from the hook connection hole, the cross-sectional width of each buffer hole near the end of the hook connection hole is smaller than the cross-sectional width away from the end of the hook connection hole.

[0014] Compared with related technologies, this application has the following advantages: (1) The exhaust hanger described in this application has a deformation part formed on the hanger bracket and located above the rubber body. The deformation part elastically deforms when the rubber body is subjected to an impact load greater than a set threshold. By utilizing the cooperation between the deformation part on the hanger bracket and the rubber body, the stiffness is weakened under low-frequency loads and the dynamic stiffness is increased under high-frequency loads. This enables the stiffness of the exhaust hanger to adaptively increase with the load frequency, improves the adaptability to load intensity, and avoids damage to the rubber body structure caused by high-intensity loads. This is beneficial to improving the overall quality of use of the exhaust hanger.

[0015] (2) The hanging bracket is formed from a plate made of spring steel, and the deformable part is formed from multiple curved structures connected in sequence, and the deformable part extends in a corrugated shape. This makes it possible for the part of the hanging bracket itself to form a deformable part that can be elastically deformed, which helps to reduce the design and manufacturing cost of the hanging bracket.

[0016] (3) A receiving space is formed on the hanging bracket, so that the rubber body is located in the receiving space, and the hanging bracket forms a wrapping around the bottom and two opposite sides of the rubber body, which facilitates the connection and setting of the rubber body on the hanging bracket, and also ensures the reliability of the connection between the rubber body and the hanging bracket.

[0017] (4) The hanging bracket includes the bracket body and the connecting arms at both ends. The structure is simple, which is conducive to the design and manufacture of the hanging bracket, and also facilitates the arrangement of the rubber body and the first connecting part on the hanging bracket.

[0018] (5) By setting deformation parts on the second part of both side walls, the setting of deformation parts on both sides can make the hanging bracket have better dynamic stiffness when the rubber body is subjected to high frequency and large load, and can also make the overall elastic deformation of the hanging bracket more stable, which can reduce or even avoid the possibility of large swing of the exhaust hanging bracket, which is conducive to ensuring the quality of use of the exhaust hanging bracket.

[0019] (6) The first connecting part adopts a connecting hole, which is simple in structure, easy to form, and also helps to realize the connection between the exhaust hanger and the vehicle body by means of screw connection, etc.

[0020] (7) The second connection part adopts a hook connection hole that is set through the rubber body. It has a simple structure, is easy to form, and can facilitate the connection between the rubber body and the hook on the exhaust system, so as to realize the connection between the exhaust hanger and the exhaust system.

[0021] (8) Multiple buffer holes arranged around the hook connection hole are provided on the rubber body to buffer the force and vibration energy borne by the hook connection hole on the rubber body, which can release and isolate the vibration energy and help improve the vibration isolation and buffering effect of the rubber body.

[0022] (9) The cross-sectional width of each buffer hole near the hook connection hole is smaller than that of the end away from the hook connection hole. This helps to ensure the structural strength of the hanging connection hole area while ensuring the buffer hole has a better buffering capacity. It also ensures the reliability of the connection between the hook on the rubber body and the exhaust system, and is conducive to improving the durability of the exhaust hanger.

[0023] Another object of this application is to provide a vehicle having an exhaust suspension as described above.

[0024] The vehicle described in this application, through the exhaust suspension configuration as described above, enables the exhaust suspension stiffness to adaptively increase with load frequency, improving its adaptability to load intensity. At the same time, it can also avoid damage to the rubber structure caused by high-intensity loads, which is beneficial to improving the overall quality of use of the exhaust suspension, thereby improving the quality of use of the vehicle.

[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.

[0028] Furthermore, it should be noted that in the description of this application, if terms such as "upper," "lower," "inner," or "outer" appear, indicating orientation or positional relationship, these are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. 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 hanger that is applied to the chassis of a vehicle and is mainly used for suspending and mounting the vehicle's exhaust system. Furthermore, the exhaust hanger in this embodiment, through its innovative structural design, can improve the quality of use of the exhaust hanger.

[0033] In related technologies, vehicles vibrate during operation due to factors such as the periodic combustion of the engine and the pulsation of exhaust airflow. If the vibrations are transmitted directly to the vehicle frame without isolation, they can easily cause resonance of the vehicle body and generate significant noise pollution. They may also cause the exhaust system to collide and interfere with surrounding components (such as chassis brackets, fuel lines, etc.), shortening the service life of the components and even posing a potential threat to the driving safety of the entire vehicle.

[0034] To meet the high demands of vehicles for NVH performance and ride comfort, existing vehicles typically incorporate rubber blocks between the exhaust suspension and the vehicle body to buffer and isolate vibrations. However, current exhaust suspensions employ a static stiffness design, with their elastic modulus remaining fixed after vulcanization. This results in a single stiffness profile, low adaptability to load intensity, and hinders the improvement of suspension structure reliability. Under high-frequency impact loads, the exhaust suspension is prone to localized stress concentration, reaching the material fatigue limit and causing it to fracture. This affects the connection stability of the exhaust system, ultimately compromising the overall quality of the exhaust suspension.

[0035] In view of this, to overcome the deficiencies existing in the related technologies, in the exhaust hanger of this embodiment, in combination with Figures 1 to 3 as shown in

[0036] In the overall design, it includes a hanger bracket 1 and a rubber body 2 fixedly connected to the hanger bracket 1.

[0037] Among them, the hanger bracket 1 is provided with a first connecting portion 3 for connecting to the vehicle body and a deformation portion 103 formed by a part of the hanger bracket 1. The rubber body 2 is provided with a second connecting portion 4 for connecting to the exhaust system. The deformation portion 103 is located above the rubber body 2, and the deformation portion 103 is adapted to elastically deform when the rubber body 2 bears an impact load greater than a set threshold.

[0038] Based on the above overall introduction, specifically, it is worth noting that for the exhaust system in this embodiment, it is generally connected to the power system of the vehicle and is mainly used to process and discharge the exhaust gas produced by the power system. It generally includes an exhaust pipe and an exhaust hook.

[0039] [[ID=1 = 15]]The exhaust hanger in this embodiment is connected to the bottom of the vehicle body through the first connecting portion 3 and is connected to the exhaust hook through the second connecting portion 4.

[0040] Generally speaking, the end of the above exhaust hook is provided with a pier head, and a retaining ring is arranged at an interval from the pier head. The above second connecting portion 4 is connected between the pier head and the retaining ring of the exhaust hook. Generally, the above exhaust hook is arranged in a "U" shape. Pier heads and retaining rings are provided at both ends of the exhaust hook. The concave portion between the two ends is used to accommodate the exhaust pipe of the exhaust system. And during assembly, after the two exhaust hangers are respectively connected to the corresponding side ends of the exhaust hook through their respective second connecting portions 4 and then connected to the vehicle body, at this time, the exhaust pipe is located between the exhaust hook and the vehicle body and is fixed to the vehicle body through the exhaust hook and the exhaust hanger.

[0041] For the structure of the above exhaust hook, in addition to adopting the above "U" - shaped structure, it can also refer to the structure of the exhaust hook in existing vehicles (such as L - shaped, etc.), which will not be elaborated here.

[0042] It should be noted that in the translation of the text related to the shape description of the exhaust hook in ID = 18, the Chinese "几" - shaped is translated as "U" - shaped here. If there is a more accurate description in the original text about the shape of the "几" - shaped object, it can be adjusted accordingly. Also, the overall translation tries to maintain the original technical and logical expressions in the patent text.The rubber body 2 can be fixedly connected to the hanging bracket 1 through a vulcanization process. The materials of the rubber body 2 and the hanging bracket 1 can be the same as the materials of the existing rubber body 2 (such as EPDM rubber) and the hanging bracket 1 (such as steel), and will not be described in detail here.

[0043] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, this embodiment may, for example, have the hanging bracket 1 formed from a plate supported by spring steel, and the deformable part 103 includes a bent structure 1031 formed by bending the hanging bracket 1 itself.

[0044] Among them, there are multiple bending structures 1031 connected in sequence, and the bending directions between adjacent bending structures 1031 are opposite, so that the deformed part 103 extends in a corrugated shape.

[0045] It is understandable that by making the hanging bracket 1 a plate made of spring steel, and by making the deformable part 103 formed by a plurality of sequentially connected curved structures 1031, and by making the deformable part 103 extend in a corrugated shape, it is possible to make the deformable part 103, which can be elastically deformed, by making part of the structure of the hanging bracket 1 itself, which helps to reduce the design and manufacturing cost of the hanging bracket 1.

[0046] In specific implementation, the multiple sequentially connected bending structures 1031 are all bent from plates made of spring steel, so that the deformed part 103 extends in a corrugated shape. Each bending structure 1031 has a bending section and a connecting section on both sides of the bending section. When the hanging bracket 1 is subjected to an impact load exceeding the set threshold, the connecting sections of each bending structure 1031 are affected by the impact load and move closer or further away from each other, causing the deformed part 103 to undergo elastic deformation.

[0047] Furthermore, the above-mentioned curved sections can be, for example, U-shaped, U-shaped, or arc-shaped. The opening directions of the curved sections of each curved structure 1031 are opposite, and they are connected by connecting sections on corresponding sides, so that the deformed part 103 can extend in a corrugated shape.

[0048] It is worth noting that, taking the hanging bracket 1 as an example, which is made of spring steel and has a plate structure, the threshold setting is determined by the specific material, thickness and width of the hanging bracket 1, as well as the bending angle of the corrugated structure. In actual implementation, the threshold setting can be determined according to the specific design requirements.

[0049] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the hanging bracket 1 is still formed from a plate made of spring steel, and the deformable part 103 includes a bent structure 1031 formed by bending the hanging bracket 1 itself. In this embodiment, for example, a receiving space t can be formed on the hanging bracket 1.

[0050] The rubber body 2 is located in the receiving space t, and the hanging bracket 1 forms a wrap around the bottom of the rubber body 2 and at least two opposite sides.

[0051] It is understandable that forming a receiving space t on the hanging bracket 1 allows the rubber body 2 to be located in the receiving space t, and the hanging bracket 1 to wrap around the bottom and two opposite sides of the rubber body 2. This facilitates the connection and installation of the rubber body 2 on the hanging bracket 1, and also ensures the reliability of the connection between the rubber body 2 and the hanging bracket 1.

[0052] In practice, the rubber body 2 is vulcanized on the hanging bracket 1 and located in the accommodating space t. The bottom and sides of the rubber body 2 are vulcanized at the corresponding positions on the hanging bracket 1, and each bending structure 1031 is located above the rubber body 2.

[0053] In addition, in specific implementation, an extension structure extending into the accommodating space t can be added to the above-mentioned hanging bracket 1 to further enhance the connection strength between the rubber body 2 and the hanging bracket 1 after vulcanization. After the rubber body 2 is vulcanized on the hanging bracket 1, each extension structure is located inside the rubber body 2. In actual implementation, the depth of the above extension structure into the rubber body 2 and the number of extension structures can be set according to specific design requirements.

[0054] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, taking the hanging bracket 1 having a receiving space t and the rubber body 2 located in the receiving space t as an example, this embodiment may make the hanging bracket 1 include a "U"-shaped bracket body 101 and connecting arms 102 respectively connected to both ends of the bracket body 101.

[0055] The support body 101 has a space t inside, the rubber body 2 is connected to the support body 101, and each connecting arm 102 is provided with a first connecting part 3.

[0056] It is understandable that the hanging bracket 1 includes a bracket body 101 and connecting arms 102 at both ends. The structure is simple, which is conducive to the design and manufacture of the hanging bracket 1, and also facilitates the arrangement of the rubber body 2 and the first connecting part 3 on the hanging bracket 1.

[0057] In specific implementation, the outer contour of the rubber body 2 conforms to the outer contour of the bracket body 101. Each of the connecting arms 102 is provided with a first connecting part 3. When each connecting arm 102 is connected to the vehicle body through the first connecting part 3, at least a portion of each connecting arm 102 abuts against the bottom surface of the vehicle body. Preferably, the surface of each connecting arm 102 facing the vehicle body is matched with the surface shape of its mounting position on the vehicle body. When the hanging bracket 1 is connected to the vehicle body through the first connecting part 3, the surface of each connecting arm 102 facing the vehicle body abuts against the bottom surface of the vehicle body.

[0058] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the hanging bracket 1 still includes a bracket body 101 and a connecting arm 102 connected to the bracket body 101. In this embodiment, the bracket body 101 may include a side wall 1011 and a bottom wall 1012.

[0059] The two side walls 1011 are arranged opposite to each other, and the bottom wall 1012 is connected between the two oppositely arranged side walls 1011. Each side wall 1011 has a first part 10111 connected to the side of the rubber body 2, and a second part 10112 located above the first part 10111. The second part 10112 on each side is connected to the connecting arm 102 on the same side, and each second part 10112 on each side has a deformable part 103.

[0060] It is understandable that by providing deformation parts 103 on the second part 10112 of both side walls 1011, the deformation parts 103 on both sides can be used to make the hanging bracket 1 have better dynamic stiffness when the rubber body 2 is subjected to high frequency and large load. It can also make the overall elastic deformation of the hanging bracket 1 more stable, which can reduce or even avoid the possibility of large swing of the exhaust hanging, and help ensure the quality of use of the exhaust hanging.

[0061] In specific implementation, the bottom wall 1012 is arranged in an arc shape. The two ends of the bottom wall 1012 are respectively connected to the first part 10111 of the side wall 1011 on the same side. The deformable part 103 on the second part 10112 of each side wall 1011 can be connected to the first part 10111 or the connecting arm 102 of each side wall 1011 based on design requirements. Alternatively, each deformable part 103 can be located in the middle of the second part 10112 on the corresponding side and is not connected to the first part 10111 or the connecting arm 102 of each side wall 1011.

[0062] The location of the above-mentioned deformable part 103 can also be set according to the specific design requirements during actual implementation.

[0063] Continue to combine Figures 1 to 3As shown, in some exemplary embodiments, each connecting arm 102 is provided with a first connecting portion 3 as an example. In this embodiment, for example, the first connecting portion 3 may be a connecting hole.

[0064] Understandably, the use of connecting holes in the first connecting part 3 results in a simple structure that is easy to form, and also facilitates the connection between the exhaust hanger and the vehicle body through methods such as screwing.

[0065] In practical implementation, one of the connecting holes on the two connecting arms 102 can be, for example, a round hole, and the other can be, for example, an oblong hole, to facilitate positioning and assembly when connected to the vehicle body via the first connecting part 3. Each connecting hole is used for bolts to pass through and to be fastened to the vehicle body by bolts. Of course, the shape of the above connecting holes can also be set with reference to the shape of the connecting holes for bolts to pass through in existing vehicles (such as strip holes), which will not be elaborated here.

[0066] In addition to connecting holes, the first connecting part 3 can also use snap-fit ​​connectors. Corresponding snap-fit ​​holes are provided at the preset assembly positions on the vehicle body. By inserting the snap-fit ​​connector into the snap-fit ​​holes, the connecting part is snapped onto the vehicle body, thereby fixing the hanging bracket 1 on the vehicle body. Of course, the connection form of the first connecting part 3 can also refer to the connection form of related structures on existing vehicles (such as welding forms), which will not be elaborated here.

[0067] In addition, taking the first connecting part 3 with connecting holes as an example, each connecting arm 102 is provided with a positioning protrusion, and in conjunction with it, a positioning groove is provided on the vehicle body. The positioning protrusion can be inserted into the positioning groove to position the corresponding assembly position of the connecting hole when it is assembled on the vehicle body.

[0068] Continue to combine Figures 4 to 6 As shown, in some exemplary embodiments, this embodiment may, for example, include a second connecting portion 4 including a hook connection hole 401 extending through the rubber body 2.

[0069] It is understandable that the second connecting part 4 adopts a hook connecting hole 401 that is provided through the rubber body 2. The structure is simple, easy to form, and can facilitate the connection between the rubber body 2 and the hook on the exhaust system, so as to facilitate the connection between the exhaust hanger and the exhaust system.

[0070] In specific implementation, a recess is provided at both sides of the opening of the hook connection hole 401 to accommodate the head of the exhaust hook and the anti-reverse ring. The end of the exhaust hook passes through the hook connection hole 401 along the extension direction of the hook connection hole 401 and extends out of the rubber body 2. The head and the anti-reverse ring are located on both sides of the rubber body 2 and are located in the recess. When the exhaust hanger is displaced, it can squeeze the rubber body 2 and compress the rubber body 2, so as to absorb the energy generated by the displacement of the exhaust hanger.

[0071] Alternatively, the second connecting part 4 can also be a connecting pipe nested inside the rubber body 2, with internal threads and vulcanized onto the rubber body 2. However, in practical implementation, this type of connecting pipe is inconvenient to process and to connect the exhaust hanger and the exhaust hook; therefore, this type of connection is not used in this embodiment.

[0072] Continue to combine Figures 4 to 6 As shown, in some exemplary embodiments, taking the second connecting part 4 as the hook connecting hole 401 as an example, this embodiment may, for example, provide a buffer hole 5 arranged through the rubber body 2, and the buffer hole 5 is a plurality of circumferentially spaced ring hook connecting holes 401.

[0073] It is understandable that by setting multiple buffer holes 5 around the hook connection hole 401 on the rubber body 2, the force and vibration energy borne by the hook connection hole 401 on the rubber body 2 can be buffered, and the vibration energy can be released and isolated, which helps to improve the vibration isolation and buffering effect of the rubber body 2.

[0074] In specific implementation, the shape of each buffer hole 5 can be at least one of the following: circular hole, square hole, triangular hole, elliptical hole or irregular hole. Of course, the shape of each buffer hole 5 can also be a combination of the above shapes. In actual implementation, the corresponding selection should be made according to the specific design requirements.

[0075] In addition, the shape of each buffer hole 5 can be at least one of circular, square, triangular, elliptical or irregular holes, or it can be a variable cross-section hole. The cross-section of the buffer hole 5 changes along the extension direction of the buffer hole 5. Taking each buffer hole 5 as a triangular hole as an example, the cross-sectional width of each buffer hole 5 needs to be set according to the size of the hook connection hole 401, the size of each buffer hole 5, the thickness of the rubber body 2 and the material of the rubber body 2. In actual implementation, the cross-sectional change of the buffer hole 5 also needs to be selected according to the specific design requirements.

[0076] Continue to combine Figures 4 to 6As shown, in some exemplary embodiments, taking the rubber body 2 as an example, a plurality of buffer holes 5 arranged circumferentially at intervals with a ring hook connection hole 401, this embodiment may, for example, make the cross-section of each buffer hole 5 closer to the hook connection hole 401 wider than the cross-section wider at the end away from the hook connection hole 401 when viewed from the axial direction of the hook connection hole 401.

[0077] It is understandable that making the cross-sectional width of each buffer hole 5 closer to the hook connection hole 401 smaller than that of the end farther from the hook connection hole 401 helps to ensure the structural strength of the hanging connection hole area while giving the buffer hole 5 better buffering capacity, ensuring the reliability of the connection between the hook on the exhaust system and the rubber body 2, and improving the durability of the exhaust hanger.

[0078] In practical implementation, the cross-sectional width of each buffer hole 5 can be gradually increased from the end with the smaller cross-sectional width to the end with the larger cross-sectional width along the through direction of the buffer hole 5, or the width can be varied along the through direction. Taking six buffer holes 5 spaced circumferentially along the hook connection hole 401 as an example, and each buffer hole 5 being a triangular hole as an example, the cross-sectional width of each buffer hole 5 needs to be set according to the size of the hook connection hole 401, the size of each buffer hole 5, the thickness of the rubber body 2, and the material of the rubber body 2. In actual implementation, it is necessary to make the corresponding selection according to the specific design requirements.

[0079] Furthermore, the number of buffer holes 5, the spacing between buffer holes 5, and the spacing between buffer holes 5 and hook connection holes 401, taking as an example that there are six buffer holes 5 spaced circumferentially along the hook connection hole 401 and that each buffer hole 5 is a triangular hole, the corresponding parameters still need to be set according to the size of the hook connection hole 401, the size of each buffer hole 5, the thickness of the rubber body 2, and the material of the rubber body 2. In actual implementation, the corresponding selection needs to be made according to the specific design requirements.

[0080] It is worth noting that, regarding the exhaust hanger of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still provided by... Figures 1 to 6 As shown, it may include, for example, a hanging bracket 1 and a rubber body 2.

[0081] The rubber body 2 is vulcanized on the suspension bracket 1. The suspension bracket 1 is provided with a first connecting part 3 for connecting with the vehicle body, and a deformation part 103 formed by a part of the suspension bracket 1. The rubber body 2 is provided with a second connecting part 4 for connecting with the exhaust system. The deformation part 103 is located above the rubber body 2 and is adapted to elastically deform when the rubber body 2 is subjected to an impact load greater than a set threshold.

[0082] The hanging bracket 1 is formed by bending a plate made of spring steel. The deformable part 103 includes a bending structure 1031 formed by bending the hanging bracket 1 itself. The bending structures 1031 are connected in sequence, and the bending directions between adjacent bending structures 1031 are opposite, so that the deformable part 103 extends in a corrugated shape.

[0083] The hanging bracket 1 includes a U-shaped bracket body 101 and connecting arms 102 connected to both ends of the bracket body 101. A receiving space t is formed inside the bracket body 101. A rubber body 2 is connected to the bracket body 101 and is included by the bracket body 101 at the bottom and sides of the rubber body 2. Each connecting arm 102 is provided with a first connecting part 3.

[0084] The support body 101 includes two side walls 1011 arranged opposite to each other, and a bottom wall 1012 connected between the two side walls 1011. Each side wall 1011 has a first part 10111 connected to the side of the rubber body 2, and a second part 10112 located above the first part 10111. Each second part 10112 is connected to the connecting arm 102 on the same side, and each second part 10112 is provided with a deformation part 103.

[0085] Each connecting arm 102 has a first connecting part 3 with connecting holes, both of which are circular holes. The second connecting part 4 includes a hook connecting hole 401 that penetrates the rubber body 2. The rubber body 2 has buffer holes 5 arranged through it, with multiple buffer holes 5 arranged circumferentially around the hook connecting holes 401.

[0086] Specifically, from the axial perspective of the hook connection hole 401, the cross-sectional width of each buffer hole 5 near the end of the hook connection hole 401 is smaller than the cross-sectional width away from the end of the hook connection hole 401.

[0087] In the preferred embodiment of the exhaust hanger described above, the specific configuration and arrangement of the hanger bracket 1, rubber body 2, deformation part 103, etc. can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the hanger bracket 1, rubber body 2, deformation part 103, etc. can also be referred to the descriptions in the above exemplary embodiments.

[0088] The exhaust hanger of this embodiment adopts the above design. By forming a deformation part 103 on the hanger bracket 1 and located above the rubber body 2, the deformation part 103 elastically deforms when the rubber body 2 is subjected to an impact load greater than a set threshold. By utilizing the cooperation between the deformation part 103 on the hanger bracket 1 and the rubber body 2, the stiffness of the rubber body 2 is weakened under low-frequency loads, and the dynamic stiffness is increased by the deformation part 103 under high-frequency loads. This allows the stiffness of the exhaust hanger to adaptively increase with the load frequency, improving its adaptability to load intensity. At the same time, it can also avoid damage to the structure of the rubber body 2 caused by high-intensity loads, which is beneficial to improving the overall quality of use of the exhaust hanger.

[0089] An embodiment of the second aspect of this application provides a vehicle that is equipped with the exhaust suspension shown in the embodiment of the first aspect of this application.

[0090] In the vehicle of this embodiment, the exhaust hanger is mainly used to fix the exhaust system on the vehicle body. Furthermore, the relevant structure of the exhaust system in the vehicle of this embodiment and the connection form between the exhaust system and other structures in the vehicle can be referred to the relevant structure and connection form of the existing vehicle, and will not be described in detail here.

[0091] Furthermore, the exhaust hanger in the first aspect of the above embodiment is suitable for fixing the position of the exhaust pipe with an exhaust hook. In specific implementation, those skilled in the art can make corresponding selections according to the setting position of the exhaust hanger, the arrangement space, and the design requirements of the vehicle.

[0092] In this embodiment, the vehicle, through the exhaust suspension configuration described above, particularly through the elastic deformation of the deformation part 103, can achieve stiffness reduction under low-frequency loads and dynamic stiffness enhancement under high-frequency loads by cooperating with the deformation part 103 and the rubber body 2. This allows the stiffness of the exhaust suspension to adaptively increase with the load frequency, improving its adaptability to load intensity. At the same time, it can also prevent high-intensity loads from damaging the structure of the rubber body 2, which is beneficial to improving the overall quality of use of the exhaust suspension, reducing the frequency of vehicle maintenance, and thus improving the overall quality of vehicle use.

[0093] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
