[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] In the prior art, the ring hoop in the clamp structure for mounting the muffler is an integral member, so that the integral ring hoop has only one connection, and the locking force applied to the ring hoop during locking of the clamp structure to the outer periphery of the muffler is likely to cause the ring hoop to deform, and the ring hoop needs a large degree of deformation, so that the outer periphery of the muffler appears uneven stress, and further causes the posture of the muffler to change, resulting in that the inner stress for protecting the posture of the muffler is generated in the exhaust pipe after installation, and over a long period of time, the service life of the exhaust pipe, especially the muffler, is easily affected, thereby reducing the service life of the exhaust pipe.

[0039] The utility model provides a kind of installation support.

[0040] Please refer to Figure 1 、 Figure 5 And Figure 6 In an embodiment of the utility model, the installation support is used for mounting the muffler 400, and the installation support comprises:

[0041] A plurality of hoop bodies 100, the hoop body 100 is concave arc, and the end of the plurality of hoop bodies 100 is sequentially connected, so as to surround the outer periphery of the muffler 400;And

[0042] The connecting frame 200 is connected to the hoop body 100, the connecting frame 200 is provided with the shock pad 300, the shock pad 300 is located in the upper portion of the hoop body 100, the connecting frame 200 is used to hang and install on the vehicle body framework 500, and the shock pad 300 is used to clamp between the connecting frame 200 and the vehicle body framework 500.

[0043] The utility model discloses a technical scheme utilizes a plurality of hoop body 100 surrounds the periphery of the muffler 400, and the hoop body 100 is concave arc shape and is attached to the outside of the muffler 400, and the end of a plurality of hoop body 100 is connected in proper order, and then the stress distribution between the hoop body 100 and the muffler 400 can be changed by coordinating the stress relationship of the connecting place of a plurality of hoop body 100, and the probability of the deformation of the hoop body 100 is reduced, and the probability of the posture change of the muffler 400 is reduced in the process of locking the periphery of the muffler 400, simultaneously, the connecting frame 200 is provided with the shock pad 300 on the upper portion of the hoop body 100, and the stress between the connecting place of a plurality of hoop body 100 can also be coordinated in the stress relationship of the connecting place of the shock pad 300 and the body frame 500, and the shock pad 300 is connected to the body frame 500 in the way of hanging in the position of setting, and the stress deformation of the hoop body 100 can be reduced, and the influence of the posture of the muffler 400 in the process of installing the mounting bracket on the body frame 500 is reduced, and the shock pad 300 is used to absorb vibration energy, so that the posture of the muffler 400 is adapted to the exhaust pipe in the process of connecting and using, and the possibility of the deformation of the exhaust pipe due to stress is reduced, thereby the use stability and service life of the muffler 400 are improved.

[0044] It should be noted that a plurality of hoop body 100 is understood as at least two hoop body 100, which can be two hoop body 100, three hoop body 100 or four hoop body 100, etc., and the hoop body 100 is surrounded by the shape adapted to the periphery of the muffler 400, thereby reducing the deformation degree of a single hoop body 100, and reducing the stress on the muffler 400 in the process of deformation of the hoop body 100, so as to reduce the influence of the posture of the muffler 400 when the mounting bracket connects the muffler 400 to the body frame 500, and ensure that the muffler 400 can be installed according to the preset posture, thereby improving the stability of the muffler 400. Among them, a plurality of hoop body 100 can be consistent in size, uniformly distributed on the periphery of the muffler 400, or different in size, arranged according to the requirements of convenient installation and low influence on the posture of the muffler 400. As for the shock pad 300, the number of shock pads 300 is set according to the requirements, and the setting position can be adapted to the connecting place of the hoop body 100, such as being on the same horizontal plane of the upper portion of the hoop body 100, or being at different height positions of the upper portion of the hoop body 100, etc.

[0045] It can be understood that the part of the connecting frame 200 connected to the vehicle body frame 500 is located at the upper part of the hoop body 100, that is, at the upper part of the muffler 400. When it is installed on the vehicle body frame 500 in a hanging manner, it can reduce the probability of changing the posture of the muffler 400 due to the unevenness or instability of the connection surface between the vehicle body frame 500 and the connecting frame 200. In addition, during the hanging process, the center of gravity of the assembly formed by the muffler 400 and the mounting bracket is relatively stable and not prone to displacement. The external force borne by the hoop body 100 is low and the degree of deformation is also low, thereby ensuring that the muffler 400 can be installed according to the preset posture. As for the installation sequence, the shock-absorbing pad 300 can be fixed to the vehicle body frame 500, the hoop body 100 and the connecting frame 200 can be fixed, the muffler 400 can be fixed in the space enclosed by multiple hoop bodies 100, and then the connecting frame 200 can be connected to the vehicle body frame 500 at the position of the shock-absorbing pad 300 by hoisting; or, the shock-absorbing pad 300 can be set on the connecting frame 200, and after the muffler 400 and the installation are connected, it can be connected to the vehicle body frame 500 at the position of the shock-absorbing pad 300 by hoisting, so that the shock-absorbing pad 300 can absorb vibration energy, thereby ensuring the stability of the muffler 400.

[0046] In one embodiment, please refer to Figure 1 、 Figure 4 and Figure 5 The mounting bracket includes two hoops 100, which are arranged vertically, with their ends facing each other radially relative to the muffler 400. It is understood that the two joints between the two hoops 100 are arranged radially relative to the muffler 400, resulting in symmetrical force distribution between the two ends of the hoops 100. This achieves a certain degree of mutual offset, reducing the force that could cause the hoops 100 to change the position of the muffler 400, thereby maintaining the stability of the muffler 400. Furthermore, the vertical arrangement of the two hoops 100, with the shock-absorbing pads 300 located above the hoops 100, and the vertical alignment of the interaction between the connecting frame 200 and the vehicle body frame 500, as well as the relative positions of the two hoops 100, allows the hoops 100 to transfer external forces to the entire mounting bracket and the vehicle body frame 500 during an external impact, thereby improving the stability of the assembly formed by the mounting bracket and the muffler 400 and ensuring the proper operation of the muffler 400. Of course, in other embodiments, the mounting bracket may also include a plurality of hoops 100 , and the two hoops 100 may also be distributed horizontally, or the two hoops 100 may be distributed in a direction inclined relative to the horizontal or vertical direction.

[0047] In one embodiment, please refer to Figure 1 、 Figure 5 and Figure 6The connecting bracket 200 is provided with two shock-absorbing pads 300, which are arranged on either side of the muffler 400 in the radial direction. It will be understood that the shock-absorbing pads 300 not only absorb vibration energy between the mounting bracket and the vehicle body frame 500, but are also located at the connection between the mounting bracket and the vehicle body frame 500. The two shock-absorbing pads 300 are arranged on either side of the muffler 400 in the radial direction, indicating that the two connections between the mounting bracket and the vehicle body frame 500 are located on either side of the muffler 400 in the radial direction. This effectively balances the forces acting on the muffler 400 when external forces act on the muffler 400 or when vibrations from the vehicle body frame 500 are transmitted to the mounting bracket, thereby improving the stability of the muffler 400 on the mounting bracket. Of course, in other embodiments, the two shock-absorbing pads 300 may also be arranged along the axial direction of the muffler 400 or tilted relative to the axial or radial directions.

[0048] Regarding the connection position between the mounting bracket and the muffler 400, in this embodiment, please refer to Figure 6 The hoop body 100 and the connecting frame 200 are provided in two groups and are respectively distributed along the axial direction of the muffler 400. It should be noted that, with reference to the above-mentioned setting position of the shock-absorbing pad 300, the mounting bracket formed by one group of the connecting frame 200 and the hoop body 100 has two shock-absorbing pads 300, and the mounting bracket formed by two groups of the connecting frame 200 and the hoop body 100 has four shock-absorbing pads 300. The four shock-absorbing pads 300 are distributed in four corners along the axial and radial directions of the muffler 400, which can better balance the force on the muffler 400 and effectively filter the vibration caused by the road surface or the engine, etc., and reduce the probability of the posture of the muffler 400 changing during the installation or use of the muffler 400. Specifically, the two sets of mounting brackets are respectively adjacent to the axial ends of the muffler 400, which can better balance the axial force of the muffler 400, so that the muffler 400 maintains good stability in the axial direction, thereby reducing the internal stress of the exhaust pipe caused by the change in the posture of the installed muffler 400, thereby improving the service life of the muffler 400 and the exhaust pipe.

[0049] In one embodiment, please refer to Figures 1 to 3The connecting frame 200 includes an adapter 210, which is provided with two connecting arms 211. The connecting arms 211 extend between the shock-absorbing pad 300 and the hoop body 100. The two connecting arms 211 are connected to the hoop body 100 and are disposed on either radial side of the muffler 400. It will be appreciated that the two connecting arms 211 prevent the concentrated transmission of force between the adapter 210 and the hoop body 100 in the first direction, thereby making the force applied to the connecting frame 200 more uniform. For example, the force exerted by the connecting frame 200 on the hoop body 100 is dispersed on either radial side of the muffler 400, thereby facilitating the transmission and distribution of the force between the connecting frame 200 and the hoop body 100. Of course, in other embodiments, the hoop body 100 may be connected to the connecting frame 200 at a position corresponding to the central axis of the muffler 400 in the vertical direction. Accordingly, the at least two shock-absorbing pads 300 may be distributed along the axial or radial direction of the muffler 400.

[0050] Specifically, in this embodiment, please refer to Figure 1 and Figure 2 The connecting arm 211 is connected to the hoop body 100 by welding. It can be understood that welding, as a relatively stable connection method, can ensure the stability of the connection between the connecting arm 211 and the hoop body 100. At the same time, welding has a low impact on the structural strength of the connecting arm 211 and the hoop body 100, so that the connecting frame 200 and the hoop body 100 form a stable and good structure, ensuring that the force between the muffler 400 and the hoop body 100 can be stably transmitted along the connecting frame 200 to the vehicle body frame 500. In addition, welding does not require additional connecting parts, simplifies the connection structure between the connecting frame 200 and the hoop body 100, and can improve the connection efficiency of the connecting frame 200 and the hoop body 100. Of course, in other embodiments, the connecting arm 211 can also be connected to the hoop body 100 by screwing or clamping.

[0051] Further, in this embodiment, please refer to Figure 1 and Figure 2 The connecting frame 200 also includes a reinforcing sheet 212, which is welded to the connection between the connecting arm 211 and the hoop body 100. When the entire mounting bracket is subjected to external forces, stress concentration is easily generated at the connection between the connecting arm 211 and the hoop body 100. The reinforcing sheet 212 enriches the connection structure between the connecting arm 211 and the hoop body 100, effectively dispersing stress and improving the connection stability between the connecting frame 200 and the hoop body 100. At the same time, the reinforcing sheet 212 also improves the reliability of force transmission between the hoop body 100 and the connecting frame 200, ensuring that the hoop body 100 and the connecting frame 200 form a good integrated whole, thereby ensuring the stability of the muffler 400. Referring to the above description of the welding of the connecting arm 211 to the hoop body 100, the reinforcing sheet 212 is also welded to the connection between the connecting arm 211 and the hoop body 100, effectively strengthening the connection strength between the connecting frame 200 and the hoop body 100.

[0052] For the connection position between the connecting arm 211 and the hoop body 100, please continue to refer to Figure 1 and Figure 2 In this embodiment, the connecting arm 211 is disposed adjacent to the connection between two adjacent ferrule bodies 100. It will be appreciated that the forces acting between the muffler 400 and the ferrule body 100 can be more directly transmitted to the connecting frame 200, thereby shortening the force transmission path, reducing the intensity of external forces acting on the ferrule body 100, and ensuring that the posture and shape of the ferrule body 100 are adapted to the outer periphery and posture of the muffler 400, thereby ensuring the stability of the muffler 400. Referring to the aforementioned vertical distribution of the two ferrule bodies 100 and the radial distribution of the connection between the two ferrule bodies 100, the two connecting arms 211 are similarly distributed radially along the muffler 400, with a spacing smaller than the spacing between the two connection points of the two ferrule bodies 100, presenting a symmetrical distribution along the central axis of the muffler 400, thereby ensuring the structural strength of the connecting frame 200 and the ferrule body 100. Of course, in other embodiments, the connecting arm 211 may also be connected to the middle of the two connection points of the two adjacent ferrule bodies 100.

[0053] In one embodiment, please refer to Figure 2 and Figure 3 The connecting frame 200 further includes a connecting rod 220, and the shock-absorbing pad 300 is disposed at the end of the connecting rod 220. The adapter 210 further includes a cross arm 213, which is connected between the two connecting arms 211 and connected in parallel to the connecting rod 220. Without loss of generality, the two connecting arms 211 are disposed in parallel, and the end of the connecting rod 220 is disposed to extend further than the adapter 210. Since the shock-absorbing pad 300 is disposed at the end of the connecting rod 220, and the cross arm 213 of the adapter 210 is connected between the two connecting arms 211 and connected in parallel to the connecting rod 220, this structure forms a relatively integrated frame structure. When installing the shock-absorbing pad 300, this integrated structure provides a clear installation positioning point for the shock-absorbing pad 300. At the same time, due to the connection between the connecting rod 220 and the cross arm 213, the force applied to the shock-absorbing pad 300 during installation can be better shared by the adapter 210 and the connecting rod 220. In addition, the two connecting arms 211 extend in parallel, allowing the adapter 210 to have better balance in the radial direction of the muffler 400 and adapting to the mutual force of the two hoop bodies 100 when they are vertically distributed, thereby improving the integrity of the connecting frame 200 and the hoop body 100 after molding and ensuring the stability of the muffler 400. Of course, in other embodiments, each of the two connecting arms 211 can be independently provided with a shock-absorbing pad 300, and connected to the vehicle body frame 500 at the shock-absorbing pad 300.

[0054] Further, in this embodiment, please refer to Figure 1 、 Figure 5 and Figure 6 The mounting bracket includes two hoop bodies 100, the extension direction of the connecting rod 220 is parallel to the distribution direction of the two end portions of the hoop bodies 100, and the connecting portion of the two hoop bodies 100 and the end portion of the connecting rod 220 are vertically opposite. This structural layout between the connecting bracket 200 and the hoop bodies 100 enables the force to be transmitted in a more direct and orderly manner between the hoop bodies 100 and the connecting bracket 200. When the hoop bodies 100 are subjected to external force, the force can be transmitted along the hoop bodies 100 to the connecting portion, and then, through the vertically opposite relationship, more smoothly to the connecting rod 220, reducing the influence of shear force. At the same time, this layout enhances the symmetry of the whole formed by the hoop bodies 100 and the connecting bracket 200, so that the stress performance of the mounting bracket in each direction is more balanced, avoiding the inclination or deformation of the mounting structure due to uneven stress, thereby ensuring the stability of the muffler 400. Of course, in other embodiments, the connecting portion of the two hoop bodies 100 can also be arranged to be staggered in the vertical direction between the end portions of the connecting rod 220.

[0055] For the structural arrangement of the adapter 210, please refer to Figure 2 and Figure 3 The adapter 210 also includes a reinforcing rib 214, which is arranged at the angle between the cross arm 213 and the connecting arm 211. It should be noted that the angle between the cross arm 213 and the connecting arm 211 is an area where stress is easily concentrated. When the adapter 210 is subjected to external force, the arrangement of the reinforcing rib 214 changes the stress distribution, effectively reducing the degree of stress concentration, and avoiding structural damage such as cracks or deformation at the angle due to excessive stress. At the same time, the presence of the reinforcing rib 214 at the angle between the cross arm 213 and the connecting arm 211 optimizes the force transmission path. When external force acts on the adapter 210, the force will be redistributed along the reinforcing rib 214, so that the force can be more smoothly transmitted inside the adapter 210, reducing the situation of excessive local stress and improving the stability of the overall structure of the adapter 210 when subjected to stress. In addition, the addition of the reinforcing rib 214 improves the structural rigidity of the angle between the cross arm 213 and the connecting arm 211, and also reduces the weight of the adapter 210. The reinforcing rib 214 provides additional support and deformation resistance, and the angle can maintain its original geometric shape, reducing the amount of structural deformation, thereby improving the structural stability of the adapter 210 in a complex stress environment. Of course, in other embodiments, the thickness of the connecting portion of the connecting arm 211 and the cross arm 213 can also be increased.

[0056] In an embodiment, please refer to Figure 1 , Figure 2 and Figure 4The mounting bracket includes two hoops 100, each of which includes connecting ears 110 at its ends. One of the connecting ears 110 of the two hoops 100 abuts against each other, while the other connecting ears 110 are spaced apart and opposed to each other. It is understood that while one of the connecting ears 110 of the two hoops 100 abuts against each other, the other connecting ears 110 of the two hoops 100 abut against each other. This provides the hoops 100 with a certain degree of structural flexibility and adaptability to shape changes of the muffler 400, effectively improving the compatibility between the hoops 100 and the muffler 400 and ensuring the stability of the muffler 400 within the hoops 100. During operation, the muffler 400 may undergo slight changes in size and shape due to factors such as temperature changes and internal pressure changes. The spaced-apart connecting ears 110 allow the hoops 100 to adjust appropriately to accommodate these changes. Furthermore, although the spaced-apart connecting ears 110 do not directly abut against each other, they still play a role in force transmission and balance. When the muffler 400 is subjected to uneven forces, such as the forces generated in an area with large local vibrations, such uneven forces can be transmitted to the spaced-apart connecting ears 110 through the hoop body 100. Due to the certain spacing between the connecting ears 110, the forces can be redistributed and balanced in this area and then transmitted to the entire hoop body 100 structure and the connecting frame 200. This can prevent excessive local forces from damaging the connection between the hoop body 100 and the muffler 400, and help maintain the stability of the entire connection structure. Of course, in other embodiments, the connecting ears 110 at both ends of the two hoop bodies 100 can also abut against each other.

[0057] Further, in this embodiment, please refer to Figure 2 and Figure 4, the connecting ears 110 of the two hoop bodies 100 are connected by bolt locking. It can be understood that the bolt locking method can provide reliable connection stability and can effectively transmit force. At the same time, the locking force of the bolt can be adjusted as needed to adapt to different working conditions and requirements. For example, after the muffler 400 has been working for a period of time, the connection may become loose due to vibration and other reasons. At this time, the stability of the connection can be restored by adjusting the locking force of the bolt. In addition, the bolt locking method has the advantage of being easy to install and disassemble. When installing the muffler 400, the two hoop bodies 100 can be first installed on the muffler 400 and the vehicle body frame 500 respectively, and then connected together by bolts. This step-by-step installation method can simplify the installation process and improve work efficiency. When the muffler 400 needs to be disassembled, it is only necessary to loosen the bolts, which is simple and convenient to operate. Without loss of generality, in this embodiment, the bolt is inserted from top to bottom through the connecting ear 110, so that when the connection between the bolt and the nut fails, the bolt head can still be inserted through the connecting ear 110 of the two hoops 100 due to the action of the bolt head, thereby improving the connection stability of the two hoops 100. Of course, in other embodiments, the two hoops 100 can also be connected by means of snap connection, plug connection, etc.

[0058] In one embodiment, please refer to Figure 1 and Figure 2The connecting frame 200 is connected to the vehicle body frame 500 by means of bolt locking, and the shock pad 300 is annularly arranged on the bolt and provided with a spacer 310 at the vertical ends. It can be understood that the shock pad 300 is elastically deformed in the vertical direction, that is, the shock pad 300 is mainly in the energy absorption direction in the vertical direction. The bolt has high fastening force and can withstand various forces transmitted by the connecting frame 200 during operation, and the bolt locking mode provides a reliable connection means for the connecting frame 200 and the vehicle body frame 500. At the same time, the bolt locking mode has great convenience in the installation and maintenance of the muffler 400. For example, when the muffler 400 or the connecting frame 200 itself is damaged, the connecting frame 200 can be disassembled by loosening the bolt, which greatly improves the maintenance efficiency and reduces the maintenance cost. In addition, the shock pad 300 is annularly arranged on the bolt, which can effectively reduce the vibration transmission between the connecting frame 200 and the vehicle body frame 500. When the muffler 400 works, vibration is generated, which is transmitted to the vehicle body frame 500 through the connecting frame 200, and the shock pad 300 can effectively absorb and dissipate part of the vibration energy in the vibration direction of the muffler 400. For the spacer 310, on the one hand, the spacer 310 can prevent the shock pad 300 from being excessively compressed or displaced when subjected to a large pressure or vibration, and on the other hand, the spacer 310 can protect the shock pad 300 and the surrounding components to avoid direct contact between them and cause wear or damage. It should be noted that the spacer 310 is provided with a positioning protrusion 311, and the vehicle body frame 500 and the connecting rod 220 are provided with a positioning hole 221. During the connecting operation of the mounting bracket and the vehicle body frame 500, the positioning hole 221 and the positioning protrusion 311 are matched to position and preinstall the shock pad 300 and the connecting rod 220 or the vehicle body frame 500, thereby improving the connection convenience of the connecting frame 200 and the vehicle body frame 500. Of course, in other embodiments, the shock pad 300 can also be configured as a main spring and extend between the outer periphery of the bolt and the vehicle body frame 500 in a horizontal or relatively horizontal inclined posture.
