Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a muffler mounting structure. It also relates to a vehicle equipped with the muffler mounting structure. Background Technology

[0002] In vehicles, the exhaust system is typically suspended from the chassis using rubber muffler hangers. The relatively soft material of the muffler hanger provides cushioning, reducing the impact and friction between the exhaust system and the chassis caused by vibrations. However, when a car experiences rapid acceleration, deceleration, or bottoming out, the muffler is subjected to a powerful impact and inertial force. Due to the soft and elastic nature of the muffler hanger, the muffler moves along with it, causing the hanger to rotate around the passive side hook and become stuck.

[0003] At this time, the muffler will be in an abnormal position, and the high temperature generated by the muffler during operation may directly affect the surrounding components that should not be heated, thus causing serious problems such as burning of the surrounding components. Utility Model Content

[0004] In view of this, the present invention aims to propose a muffler mounting structure that can effectively limit the muffler suspension rotation jamming, thereby ensuring that the muffler is in the working position of the vehicle.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A muffler mounting structure includes a mounting base, and a connecting portion and a limiting portion disposed on the mounting base;

[0007] The mounting base is connected to the vehicle body, the connecting part is connected to the muffler hanger, and the limiting part is used to abut against the muffler hanger to limit the rotation angle of the muffler hanger relative to the connecting part.

[0008] Furthermore, the connecting part includes a hook disposed on the mounting base, the hook including a fixing section fixed on the mounting base and a connecting section connected to the muffler suspension;

[0009] The limiting part includes a limiting hook disposed on the mounting base corresponding to the connecting section.

[0010] Furthermore, in the vertical direction of the entire vehicle, the limiting hook is tilted downwards;

[0011] The lower part of the limiting hook has a limiting section that extends outward from the mounting base and is used to hang and abut against the muffler.

[0012] Furthermore, the limiting hook has a main body section that is angled to the limiting segment, and the main body section is connected to the mounting base; and / or,

[0013] The limiting hooks are two hooks arranged opposite each other, and the limiting segments of the two limiting hooks are arranged in a figure-eight shape.

[0014] Furthermore, the hook includes an intermediate section disposed between the fixed section and the connecting section;

[0015] The fixed section and the connecting section extend to opposite sides of the middle section, respectively.

[0016] Furthermore, the connecting segment is provided with a locking head located at the end, and a limiting protrusion spaced apart from the locking head;

[0017] The clip passes through the muffler hanger and is secured on one side of the muffler hanger, while the limiting protrusion blocks the other side of the muffler hanger.

[0018] Furthermore, the mounting base includes a motherboard and a first flange disposed at one end of the motherboard;

[0019] The main board is connected to the vehicle body, the fixing section is disposed on the main board, and the limiting hook is disposed on the first flange.

[0020] Furthermore, the mounting base includes a second flange located at the other end of the motherboard;

[0021] In the vertical direction of the entire vehicle, the first flange folds downwards, and the second flange folds upwards.

[0022] Furthermore, the mounting base is provided with two reinforcing protrusions arranged at intervals, each of the reinforcing protrusions extending from the main board to the first flange;

[0023] The two reinforcing protrusions form mounting grooves, and the fixing section is disposed in the mounting grooves.

[0024] Compared with the prior art, this utility model has the following advantages:

[0025] The muffler mounting structure of this utility model, by setting a mounting base connected to the vehicle body, and setting a connecting part and a limiting part on the mounting base, not only realizes the connection with the muffler hanger, but also the limiting part can limit the rotation angle of the muffler hanger relative to the connecting part. This can effectively prevent the muffler hanger from rotating and getting stuck under extreme conditions such as rapid acceleration, rapid deceleration or bottoming out, which helps to keep the muffler in the correct installation position and avoid abnormal posture of the muffler due to excessive rotation. This can also prevent the problem of burning of surrounding parts due to abnormal posture.

[0026] Furthermore, the connecting part includes a hook, and the limiting part includes a limiting hook corresponding to the connecting section. This design offers advantages such as simple structure and ease of design and implementation, while also facilitating the installation of the muffler hanger on the vehicle body. When the vehicle is accelerating, decelerating, or traveling on bumpy roads, the muffler hanger primarily bears downward or oblique downward forces. By tilting the limiting hook downwards, it can better align with the direction of these forces, allowing for faster contact and restraint when the muffler hanger tends to rotate due to external forces. Extending the limiting section that contacts the muffler hanger outwards from the mounting base does not affect the normal operation of the muffler hanger and can prevent its rotation under special working conditions.

[0027] Secondly, the limiting hook has a main body section set at an angle to the limiting section, which can improve the overall structural strength of the limiting hook, thereby improving the setting stability of the limiting hook and ensuring the limiting effect of the muffler suspension. Furthermore, setting the limiting hooks as two oppositely arranged can effectively limit the rotation angle of the muffler suspension under different working conditions and when there is a tendency to rotate in different directions, which is conducive to maintaining the stable posture of the muffler suspension and the muffler.

[0028] Furthermore, the hook includes an intermediate section located between the fixed section and the connecting section, with the fixed section and the connecting section extending to opposite sides of the intermediate section respectively. This allows the hook to be bent as a whole, which not only provides better structural strength and improves the stability of the mounting base and the muffler suspension, but also effectively disperses the force transmitted from the muffler suspension.

[0029] By providing a locking head at the end of the connecting section and a limiting protrusion spaced apart from the locking head, when the locking head passes through the muffler hanger, the limiting protrusion and the locking head are positioned on opposite sides of the muffler hanger, thus firmly fixing the muffler hanger between the two, thereby achieving the connection between the hook and the muffler hanger. This is convenient to operate and can improve assembly efficiency.

[0030] Furthermore, the mounting base includes a main board and a first flange located at one end of the main board. This not only gives the mounting base better structural strength but also facilitates the installation of a limit hook and improves the stability of the limit hook installation. It also simplifies manufacturing. By including a second flange in the mounting base and folding the first and second flanges in opposite directions, the structural strength of the mounting base can be further improved, making its position in the vertical direction of the vehicle more stable and less prone to shifting or displacement.

[0031] In addition, by setting two reinforcing protrusions on the mounting base and extending them from the main board to the first flange, the structural strength of the mounting base can be further improved. At the same time, the reinforcing protrusions can share and transmit external forces, preventing the connection between the main board and the first flange from deforming or cracking due to excessive force. They can also limit the offset of the fixed section relative to the mounting base, which helps to improve the stability of the hook on the mounting base.

[0032] Another objective of this utility model is to provide a vehicle having the above-described muffler mounting structure.

[0033] The vehicle described in this utility model, by setting the muffler mounting structure as described above, helps to keep the muffler in the correct mounting position, avoids serious abnormal posture of the muffler due to excessive rotation, and thus prevents the problem of burning of surrounding parts due to abnormal posture.

[0050] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] Example 1

[0052] Given the following problems in the existing technology, when a car experiences rapid acceleration, rapid deceleration, or bottoming out, the muffler 5 will move along with the muffler hanger 4, which can easily cause the muffler 5 to be in an abnormal position, resulting in serious damage such as burning of surrounding components. Therefore, this embodiment proposes a novel muffler mounting structure, including a mounting base 1, and a connecting portion and a limiting portion disposed on the mounting base 1. The mounting base 1 is connected to the vehicle body, the connecting portion is connected to the muffler hanger 4, and the limiting portion abuts against the muffler hanger 4 to limit the rotation angle of the muffler hanger 4 relative to the connecting portion.

[0053] The muffler 5 mounting structure of this embodiment, by setting a mounting base 1 connected to the vehicle body, and setting a connecting part and a limiting part on the mounting base 1, can not only realize the connection with the muffler hanger 4, but also limit the rotation angle of the muffler hanger 4 relative to the connecting part. This can effectively prevent the muffler hanger 4 from rotating and getting stuck under extreme conditions such as rapid acceleration, rapid deceleration or bottoming out, which helps to keep the muffler 5 in the correct installation position and avoid the muffler 5 from becoming seriously abnormal in posture due to excessive rotation. This can prevent the problem of burning of surrounding parts due to abnormal posture.

[0054] Based on the above overview, an exemplary structure of the muffler mounting structure in this embodiment is provided. Figures 1 to 7 As shown, to ensure noise reduction, the muffler 5 typically has a certain length. Therefore, to ensure the installation stability of the muffler 5, mounting structures for mounting it onto the vehicle body are generally provided at both ends of the muffler 5. Furthermore, generally, both ends of the muffler 5 are hooked onto the muffler hanger 4 via mounting hooks 6, and as shown... Figure 3 As shown, the structure of the muffler hanger 4 is the same as that of the prior art. It is made of rubber and usually has upper and lower hanging holes arranged at intervals. The mounting hook 6 is hooked into the lower hanging hole.

[0055] Furthermore, in specific implementation, depending on the installation structure of the muffler 5, the installation structures on both sides of the muffler 5 can adopt the following structure. Or, as... Figure 1 As shown, only the mounting structure on one side of the muffler 5 adopts the following structure, while the mounting structure on the other side adopts the existing structure. Wherein, as... Figure 1 and Figure 2 As shown, because the mounting hook 6 at the left end of the muffler 5 is arranged along the left-right direction of the vehicle, the muffler 5 and the muffler hanger 4 may rotate back and forth around the connection when the vehicle is under extreme operating conditions. Therefore, by adopting the following mounting structure on this side, the back-and-forth rotation of the muffler hanger 4 on this side can be restricted and locked, so as to keep the muffler 5 in the normal working position.

[0056] For ease of understanding, the structure of the mounting base 1 will be described first. In a preferred embodiment, the mounting base 1 includes a main board 101 and a first flange 102 located at one end of the main board 101. The main board 101 is connected to the vehicle body, the fixing section 201 is located on the main board 101, and the limiting hook 3 is located on the first flange 102. This structure not only provides the mounting base 1 with good structural strength but also facilitates the installation of the limiting hook 3 and improves the stability of the limiting hook 3. Furthermore, it is also easy to manufacture. And, as a specific embodiment, combined with… Figures 2 to 5As shown, the mainboard 101 is roughly rectangular in shape, and the first flange 102 is set at an obtuse angle to the mainboard 101. In addition, mounting holes are provided at both ends of the mainboard 101, and the mainboard 101 can be mounted on the vehicle body by fasteners such as bolts passing through the mounting holes.

[0057] As a further implementation method, such as Figure 4 As shown, the mounting base 1 includes a second flange 103 located at the other end of the main board 101. In the vertical direction of the vehicle, the first flange 102 folds downwards, and the second flange 103 folds upwards. The arrangement of the first flange 102 and the second flange 103, and their folding in different directions, further enhances the structural strength of the mounting base 1, making it less prone to shifting or displacement. Moreover, when the vehicle is under extreme conditions of acceleration or deceleration, the bidirectional folding structure, together with the main board 101, can more stably support the weight of the muffler 5 and related components, preventing the mounting base 1 from becoming loose or deformed, thereby ensuring the stability of the entire muffler mounting structure.

[0058] Based on the above structure of the mounting base 1, in order to improve the installation stability of the hook 2 as described below, such as Figures 4 to 6 As shown, the mounting base 1 has two spaced-apart reinforcing protrusions 1021, each extending from the main board 101 to the first flange 102. Furthermore, the two reinforcing protrusions 1021 form a mounting groove, in which the fixing section 201 is disposed. This arrangement further enhances the structural strength of the mounting base 1. Simultaneously, the reinforcing protrusions 1021 can share and transmit external forces, preventing deformation and cracking at the connection between the main board 101 and the first flange 102 due to excessive force, thus improving the overall bending and torsional resistance of the mounting base 1.

[0059] Furthermore, the mounting groove provides precise positioning for the fixed section 201. By placing the fixed section 201 within the mounting groove, its movement within the plane is strictly limited, ensuring a more fixed position on the mounting base 1 and preventing loosening or displacement. This ensures the muffler 5 maintains a normal suspension state during vehicle operation, reducing exhaust system vibration and noise issues caused by unstable connections, and improving the reliability and durability of the entire muffler 5 mounting structure.

[0060] Combination Figures 1 to 4 As shown in the diagram, in a preferred embodiment, the connecting portion includes a hook 2 disposed on the mounting base 1. The hook 2 includes a fixing section 201 fixed to the mounting base 1 and a connecting section 202 connected to the muffler hanger 4. The limiting portion includes a limiting hook 3 disposed on the mounting base 1 corresponding to the connecting section 202. Wherein, as... Figure 6As shown, the limiting hook 3 is positioned corresponding to the connecting section 202, meaning that when viewed from the left rear direction of the vehicle, the limiting hook 3 is approximately located directly above the connecting section 202. This embodiment includes a hook 2 as the connecting part and a limiting part including a limiting hook 3 positioned corresponding to the connecting section 202. This design offers advantages such as simple structure and ease of design and implementation, while also facilitating the installation of the muffler hanger 4 on the vehicle body.

[0061] In addition, such as Figure 6 and Figure 7 As shown in the diagram, in a further embodiment, the hook 2 includes an intermediate section 203 disposed between the fixed section 201 and the connecting section 202, with the fixed section 201 and the connecting section 202 extending to opposite sides of the intermediate section 203, respectively. In this embodiment, the fixed section 201 and the connecting section 202 of the hook 2 extending to opposite sides of the intermediate section 203 allow the hook 2 to form a Z-shaped bend. On one hand, this gives the hook 2 better structural strength, improving its stability on the mounting base 1 and the muffler hanger 4. On the other hand, during vehicle operation, under various complex external forces, each segment of the hook 2 can decompose the force along different directions according to its unique structural characteristics, avoiding stress concentration at a single point.

[0062] Here, it is understood that, in addition to extending the fixed section 201 and the connecting section 202 to opposite sides of the intermediate section 203 respectively, the fixed section 201 and the connecting section 202 can also extend to the same side of the intermediate section 203, as long as they do not interfere with other components.

[0063] In addition, to achieve the connection between hook 2 and the hanger, as a preferred embodiment, such as Figure 4 As shown, the connecting section 202 is provided with a locking head 2021 at its end and a limiting protrusion 2022 spaced apart from the locking head 2021. Furthermore, the locking head 2021 passes through the muffler hanger 4 and is locked onto one side of the muffler hanger 4, while the limiting protrusion 2022 blocks the other side of the muffler hanger 4. In this embodiment, by providing the spaced-apart locking heads 2021 and limiting protrusions 2022 on the connecting section 202, they can jointly limit the movement of the muffler hanger 4.

[0064] Furthermore, during the automobile production and assembly process, workers only need to pass the clip 2021 through the corresponding hole in the muffler hanger 4, and then let the limiting protrusion 2022 naturally block it on the other side to complete the installation. This convenient operation improves assembly efficiency. At this point, to further improve assembly efficiency, such as... Figure 6 and Figure 7 As shown, the outer surface of the 2021 clasp is constructed as a conical surface to guide the 2021 clasp through the upper hanging hole of the muffler hanger 4.

[0065] In this embodiment, combined with Figures 2 to 6 As shown, in the vertical direction of the vehicle, the limiting hook 3 is inclined downwards, and the lower part of the limiting hook 3 has a limiting section 302. The limiting section 302 extends outwards from the mounting base 1 and is used to abut against the muffler hanger 4. Since the muffler hanger 4 mainly bears downward or oblique downward forces when the vehicle is accelerating, decelerating, or driving on bumpy roads, the downwardly inclined limiting hook 3 can better conform to the direction of these forces. When the muffler hanger 4 tends to rotate due to external forces, it can more quickly and naturally contact the hanger and play a limiting role. Extending the limiting section 302, which is used to abut against the muffler hanger 4, outwards from the mounting base 1 does not affect the normal operation of the muffler hanger 4, and can also limit its rotation under special working conditions.

[0066] In one preferred embodiment, combined with Figures 2 to 6 As shown, the limiting hook 3 in this embodiment has a main body section 301 that is angled to the limiting section 302, and the main body section 301 is connected to the mounting base 1. The limiting hook 3 in this embodiment is composed of the main body section 301 and the limiting section 302, which are angled together, resulting in a bent structure for the limiting hook 3. This provides better structural strength, improves the stability of the limiting hook 3, and ensures the limiting effect on the muffler hanger 4. Furthermore, based on the specific structure of the mounting base 1 described above, as... Figure 5 As shown, the main body segment 301 is welded to the main board 101 of the mounting base 1.

[0067] Furthermore, in a preferred embodiment, the limiting hooks 3 are arranged in two opposite directions, with the limiting sections 302 of the two limiting hooks 3 arranged in a figure-eight shape. By setting two limiting hooks 3, a balanced restraining force can be formed on the muffler hanger 4 from both sides. They are located on both sides of the connecting section 202 of the muffler hanger 4, so that no matter which side the muffler hanger 4 tends to rotate, the corresponding limiting hook 3 can play a timely restraining role, which helps to maintain the stable posture of the muffler hanger 4 and the muffler 5.

[0068] Furthermore, the limiting sections 302 of the two limiting hooks 3 are arranged in a figure-eight shape, so that the opening direction of the figure-eight shape matches the direction of the muffler hanger 4's potentially large-amplitude rotation during vehicle movement. As the rotation angle of the muffler hanger 4 gradually increases, it can more naturally contact and be restricted by the limiting sections 302 of the limiting hooks 3. Compared to a single limiting hook 3 or parallel-arranged limiting sections 302, this provides a better limiting effect.

[0069] It should be noted that, in addition to providing two limiting hooks 3, limiting hooks 3 can also be provided on only one side of the connecting section 202, depending on design requirements. Furthermore, besides providing the two limiting hooks 3 separately, they can also be integrally formed, as long as there are two limiting sections 302. Additionally, besides making the main body section 301 and the limiting section 302 form an angle, they can also be arranged in a straight line; however, this may reduce the structural strength of the limiting hooks 3.

[0070] Based on the above overall description, the muffler installation structure of this embodiment, by adopting the above structure, when the hook 1 is connected to the muffler hanger 4, enables the limiting sections 302 of the two limiting hooks 3 to be located on both sides of the muffler hanger 4, which can effectively limit the rotation angle of the muffler hanger 4 relative to the hook 2 from both sides. Thus, under extreme working conditions such as rapid acceleration, rapid deceleration or bottoming out, it is beneficial to keep the muffler 5 in the correct installation position, and can effectively avoid the problem of the muffler 5 burning the surrounding parts due to abnormal posture.

[0074] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
