[0028] It should also be understood that although the present invention has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present invention that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0029] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0030] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0031] The first embodiment of the utility model provides a hanging structure, such as Figure 1 and Figure 2 As shown, the hanging structure includes a first hanging assembly 1 installed on the muffler, the first hanging assembly 1 includes a first main hook 11, a first auxiliary hook 12 and a hook bracket 13, one end of the first main hook 11 is connected to the end cover of the muffler, the other end of the first main hook 11 is connected to the vehicle body, the hook bracket 13 is connected between the two pipes of the muffler, and the first auxiliary hook 12 is connected between the first main hook 11 and the hook bracket 13. The first main hook 11, the first auxiliary hook 12 and the hook bracket 13 are connected to form the first hanging assembly 1, and the end cover of the muffler is connected to different pipes through a first hanging assembly 1, and there is no need to arrange a hook on each pipe, thereby reducing the number of hooks used on the muffler pipe, achieving the effect of weight reduction, and reducing costs. At the same time, two different pipes are hung together through the hook bracket 13 to ensure the reliability of the hanging structure.

[0032] Specifically, the interval between the two pipelines is smaller than the interval threshold. The interval between the two pipelines installed with the first hanging assembly 1 should be small, so that it is possible to connect the two ends of the hook bracket 13 to the two muffler pipelines respectively, for example, the first end of the muffler is installed with a main pipe 101, and the second end of the muffler is installed with a branch pipe 102 facing the first end of the muffler, and the interval between the main pipe 101 and the branch pipe 102 is smaller than the interval threshold; or one end of the muffler is respectively connected to two pipelines set at intervals, and the interval between the two pipelines is smaller than the interval threshold.

[0033] Specifically, Figure 3As shown, the first main hook 11 includes a fixed section 111, a support section 112 and a connecting section 113 which are connected in sequence. The fixed section 111 is connected to the end cover of the muffler as a whole, and has a sufficient contact area with the end cover of the muffler, thereby improving the installation stability of the first main hook 11 and the muffler; the supporting section 112 is formed by bending outward along one end of the fixed section 111, wherein the supporting section 112 is connected to one end of the first auxiliary hook 12, and the supporting section 112 and the first auxiliary hook 12 have a partial overlap (the first auxiliary hook 12 is connected to the middle of the first main hook 11), so that there is a large contact area between the supporting section 112 and the first auxiliary hook 12, thereby improving the connection stability between the two. Furthermore, the connecting section 113 is bent outward along one end of the supporting section 112, so that the free end of the connecting section 113 is connected to the vehicle body through a lifting ear, wherein the end of the connecting section 113 connected to the vehicle body has a snap-on protrusion 114. The engaging protrusion 114 guides the connection between the connecting section 113 and the lifting ear, and prevents the connecting section 113 from being separated from the lifting ear, thereby improving the safety performance of the connection between the first hanging assembly 1 and the vehicle body.

[0034] Furthermore, if Figure 2 and 4 As shown, one end of the hook bracket 13 is connected to the first pipeline 103 of the muffler, the other end of the hook bracket 13 is connected to the second pipeline 104 of the muffler, one end of the first auxiliary hook 12 is connected to the middle of the hook bracket 13, and the other end of the first auxiliary hook 12 is connected to the middle of the first main hook 11. The two ends of the hook bracket 13 are respectively connected to the first pipeline 103 and the second pipeline 104 of the muffler, and there is no need to respectively set hooks in the first pipeline 103 and the second pipeline 104, which is conducive to reducing the number of hooks. An auxiliary hook positioning part is provided in the middle of the hook bracket 13 for connecting with the first auxiliary hook 12. For example, the auxiliary hook positioning part can be set as a groove structure, which can increase the contact area between the first auxiliary hook 12 and the hook bracket 13. At the same time, part of the structure of the first auxiliary hook 12 is accommodated in the groove structure, so that the first auxiliary hook 12 is not easily displaced.

[0035] The first pipeline 103 and the second pipeline 104 are both high-frequency pipes. The first pipeline 103 and the second pipeline 104 are respectively arranged on the main pipe 101 and the branch pipe 102 of the muffler. The hook bracket 13 is connected between the two high-frequency pipes to support the heavy high-frequency pipe and improve the supporting performance of the first hanging component 1 on the high-frequency pipe.

[0036] The cross section of the hook bracket 13 is "M"-shaped, arc-shaped or trapezoidal. Taking the cross section of the hook bracket 13 as an example, the structure of the hook bracket 13 is described in detail. The hook bracket 13 includes an integrally formed bottom plate 131, a side plate 132 and a reinforcing plate 133. The two ends of the bottom plate 131 extend outward with side plates 132. The lengths of the two side plates 132 can be adaptively adjusted according to the distance between the bottom plate 131 and the first pipeline 103, and the bottom plate 131 and the second pipeline 104. The end of the side plate 132 has a connecting flange 135, and the side plate 132 is connected to the main pipe 101 and the branch pipe 102 respectively through the connecting flange 135, so that the hook bracket 13 has a larger contact area when connected to the main pipe 101 and the branch pipe 102, thereby improving the structural rigidity. Reinforcement plates 133 extend outwardly from both sides of the bottom plate 131 and the side plates 132 to improve the rigidity of the hook bracket 13. The reinforcement plates 133 on both sides form a groove structure with the bottom plate 131 and the side plates 132 to improve the energy absorption and collapse capability of the hook bracket 13. A first mounting groove 134 for mounting the first auxiliary hook 12 is provided on the bottom plate 131. The first mounting groove 134 is adapted to a part of the hook body of the first auxiliary hook 12, so that the connection between the first mounting groove 134 and the first auxiliary hook 12 is not easy to tear, the structural rigidity and stability are good, and the first auxiliary hook 12 is not easy to move. By optimizing the structure of the hook bracket 13, its rigidity is improved, which is conducive to ensuring durability.

[0037] In some embodiments, Figure 2 As shown, the suspension structure also includes a second suspension component 2, and the second suspension component 2 includes a second main hook 21 and a second auxiliary hook 22. One end of the second main hook 21 is connected to the end cover of the muffler, and the other end of the second main hook 21 is connected to the vehicle body. One end of the second auxiliary hook 22 is connected to the end cover of the muffler, and the other end of the second auxiliary hook 22 is connected to the second main hook 21. One end of the second main hook 21 is connected to the end cover of the muffler with a large contact area, which ensures the connection stability and reliability of the second suspension component 2 and the muffler. Even if the pipeline has a large vibration during the driving of the vehicle, the second suspension component 2 is not easy to detach from the muffler. The second auxiliary hook 22 is connected between the end cover of the muffler and the second main hook 21, and the second auxiliary hook 22 and the second main hook 21 have an overlapping section, which further enhances the rigidity and connection stability of the second suspension component 2. Exemplarily, the second suspension component 2 can be arranged at the upper edge or lower edge of the end cover of the muffler. As shown Figure 1 and Figure 2As shown, the second hanging component 2 can be set on the end cover of the same muffler together with the first hanging component 1, and the two are used together to further avoid the vibration of the muffler being transmitted to the vehicle body through the hanging ear, causing the vehicle body to vibrate; and the second hanging component 2 is used together with the first hanging component 1 to strengthen the connection between the muffler and the vehicle body, further improve the stability of the connection between the muffler and the vehicle body, and improve the reliability of the hanging structure.

[0038] In some embodiments, Figure 1 and Figure 5 As shown, the suspension structure also includes a third suspension component 3, which includes a mounting bracket 31 and a third hook 32. The mounting bracket 31 is mounted on the end cover of the muffler, one end of the third hook 32 is connected to the mounting bracket 31, and the other end of the third hook 32 is connected to the vehicle body. The mounting bracket 31 includes a bracket body 311 and legs 312 arranged circumferentially along the bracket body 311. The mounting bracket 31 is provided with a plurality of legs 312 along the circumference, and the plurality of legs 312 are respectively connected to the end cover of the muffler. The legs 312 and the end cover of the muffler are in surface contact, so that the contact area between the legs 312 and the end cover of the muffler is large. The position where the third suspension component 3 is provided on the muffler can release stress, and transmit vibration to the legs 312 instead of to the vehicle body.

[0039] Furthermore, a hook installation position for installing the third hook 32 is provided on one side of the bracket body 311, and the hook installation position can be set as a third installation groove 33. Part of the hook body of the third hook 32 is arranged in the third installation groove 33, which improves the connection stability between the third hook 32 and the mounting bracket 31 and avoids displacement of the third hook 32. Similar to the above-mentioned second hanging component 2, the third hanging component 3 can be used together with the first hanging component 1 on the same muffler to improve the hanging stability of the exhaust system and the stability and reliability of the connection with the vehicle body. The third hanging component 3 can also be installed on different mufflers with the first hanging component 1 to improve the hanging stability of the exhaust system.

[0040] In some embodiments, Figure 5As shown, the hanging structure also includes a fourth hanging assembly 4 installed on the pipeline of the muffler, and the fourth hanging assembly 4 includes a fourth main hook 41 and a fourth auxiliary hook 42. One end of the fourth main hook 41 is connected to the pipeline, and the other end of the fourth main hook 41 is connected to the vehicle body. One end of the fourth auxiliary hook 42 is connected to the pipeline, and the other end of the fourth auxiliary hook 42 is connected to the fourth main hook 41. The fourth hanging assembly 4 is installed on the pipeline of the muffler to provide multiple hanging points for the exhaust system and improve the hanging stability of the exhaust system. In the fourth hanging assembly 4, the fourth main hook 41 includes a first pipe section connected to the pipeline, and the fourth auxiliary hook 42 includes a second pipe section connected to the pipeline. The first pipe section and the second pipe section are connected to the pipeline from both sides of the pipeline respectively, and surround the pipeline to ensure the connection reliability of the fourth hanging assembly 4 and the pipeline. The part of the fourth main hook 41 extending out of the pipeline and the part of the fourth auxiliary hook 42 extending out of the pipeline have an overlapping section, which strengthens the rigidity and connection stability of the fourth hanging assembly 4.

[0041] Among them, the fourth hanging assembly 4 can be provided with multiple, respectively installed at different positions on different pipelines of the muffler. For example, the fourth hanging assembly 4 can be set on the exhaust pipe of the muffler, such as the main pipe 101 or the branch pipe 102. The fourth hanging assembly 4 is preferably installed on the periphery of the high-frequency pipe or near the connection between the two pipelines to ensure the hanging stability of the exhaust system. In some embodiments, the hook bracket 13 and the mounting bracket 31 are an integrated structure, which is easy to process and shape.

[0042] In addition, the first main hook 11 and the first auxiliary hook 12 are both hollow tubular structures, which is conducive to reducing the weight of the exhaust system. Further, the second main hook 21, the second auxiliary hook 22, the fourth main hook 41, and the fourth auxiliary hook 42 are also hollow tubular structures.

[0043] In order to reduce the influence of the position of the hanging point of the automobile exhaust system on the NVH (Noise, Vibration, Harshness) performance of the whole vehicle, in the specific implementation, the HyperMesh software can be used to perform finite element modeling of the automobile exhaust system to obtain the natural vibration mode of the exhaust system, and then the average driven degree of freedom displacement method (Average driven degree of freedom displacement method, ADDOFD) is used to design the hanging position of the exhaust system in combination with the overall structure of the exhaust system. When using the average driven degree of freedom displacement method, N reference points are first selected at equal intervals along the entire exhaust system, and the average driven degree of freedom displacement of each reference point is calculated. Then, the reference point with a smaller average driven degree of freedom displacement is used as the hanging arrangement point of the exhaust system. The point with a smaller average driven degree of freedom displacement is not easily excited to produce a large vibration, which can effectively prevent the vibration of the exhaust system from being transmitted to the vehicle body. For example, when the suspension is arranged at the front cover of the muffler, its average driven degree of freedom displacement is small, which is a better suspension arrangement position; when the suspension is arranged at the rear cover of the muffler, its average driven degree of freedom displacement is large, but in order to ensure the static balance of the entire exhaust system, a suspension assembly can be arranged at the rear cover of the muffler. The specific method of determining the size of the average driven degree of freedom displacement according to the average driven degree of freedom displacement method can refer to the existing technology and will not be repeated here.

[0044] In the present invention, an exhaust system including a first muffler 100 and a second muffler 200 connected in series is taken as an example to illustrate the durability of the hanging structure.

[0045] The first end of the second muffler 200 is connected to the second end of the first muffler 100 , the second end of the second muffler 200 is connected to the first ventilation pipe 201 , and the side of the second muffler 200 is connected to the second ventilation pipe 202 .

[0046] The first end of the first muffler 100 is connected to a main pipe 101, and the second end of the first muffler 100 is connected to a branch pipe 102, and the branch pipe 102 extends from the second end to the first end, so that the distance between the main pipe 101 and the branch pipe 102 is less than the interval threshold. The position of the first hanging component 1 is arranged for the purpose of weight reduction, so that it is connected to the end cover of the first muffler 100, the main pipe 101 and the branch pipe 102 respectively; the second hanging component 2, the third hanging component 3 and the fourth hanging component 4 are further arranged according to the average driving degree of freedom displacement of the exhaust system.

[0047] Specifically, the first hanging assembly 1 is arranged at the upper edge of the end cover at one end of the first muffler 100, the second hanging assembly 2 is arranged at the lower edge of the end cover at both ends of the first muffler 100, the third hanging assembly 3 is arranged at the upper edge of the end cover at one end of the second muffler 200, and four fourth hanging assemblies 4 are provided, and are respectively arranged on the main pipe 101, the first ventilation pipe 201, the high-frequency pipe of the first ventilation pipe 201 and the high-frequency pipe of the second ventilation pipe 202.

[0048] A static load of 1G is applied to the first muffler 100 and the second muffler 200 (i.e., the exhaust system is in a static load state), and the vertical (Z-direction) displacement of each hanging component and the force received are used as durability indicators for analysis. If the vertical displacement of the hanging component exceeds the displacement target value (e.g., 5mm), or the force received exceeds the force target value (e.g., 70N), it indicates that the durability of the hanging component is unqualified. Each hanging component in this embodiment meets the durability indicators.

[0049] Furthermore, a stress analysis is performed on the first muffler 100 and the second muffler 200 as a whole. If the stress of a certain hanging component exceeds the stress target value (eg, 150 MPa), it indicates that the durability of the hanging component is unqualified. Each hanging component in this embodiment meets the durability index.

[0050] This means that only one first hanging assembly 1 is provided between the main pipe 101 and the branch pipe 102 of the first muffler 100, and the hanging structures of the second hanging assembly 2, the third hanging assembly 3 and the fourth hanging assembly 4 are arranged according to this embodiment, and each hanging assembly can ensure durability.
