[0043] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.

[0044] In the description of the utility model, it should be noted that the orientation or position relationship indicated by the terms "upper", "lower", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0045] In addition, in the description of the utility model, unless otherwise explicitly limited, the terms "mounting", "connection", "connection", "connecting piece" should be understood broadly. For example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood in combination with the specific situation.

[0046] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0047] In view of the prior art, when there is a need to change the limiting direction of the rubber hanger of the vehicle exhaust system (i.e. the direction in which the rubber hanger limits the movement of the exhaust system relative to the vehicle body), the welding direction of the exhaust side and the vehicle body side hooks needs to be adjusted at the same time, therefore, there are many disadvantages such as increased adjustment cost and longer time consumption. Therefore, the present embodiment is particularly related to an exhaust system hanger structure, which comprises a first hanger 1 connected to one of the vehicle body and the exhaust system, and a second hanger 2 connected to the other of the vehicle body and the exhaust system.

[0048] The first hanging piece 1 and the second hanging piece 2 are connected through the connecting assembly arranged at one of the connection positions, and the first hanging piece 1 and the second hanging piece 2 can be connected together through the connecting assembly arranged at the other connection position after being rotated relative to each other.

[0049] The exhaust system hanging structure of the embodiment is connected through the connecting assembly arranged at one of the connection positions, and the first hanging piece 1 and the second hanging piece 2 can be connected together through the connecting assembly arranged at the other connection position after being rotated relative to each other.

[0050] Therefore, the exhaust system hanging structure of the embodiment can conveniently change the limiting direction of the exhaust system relative to the vehicle body, without simultaneously adjusting the welding direction of the exhaust side and the vehicle body side hooks and the corresponding tooling as in the traditional structure. Only the switching of the connecting assembly at different connection positions is needed, which can greatly reduce the product change cost and cycle, and can improve the adjustment efficiency of the test vehicle in the research and development process and the after-sales maintenance efficiency, and can effectively prevent damage.

[0051] Based on the above overall introduction, one exemplary structure of the exhaust system hanging structure of the embodiment is shown in Figures 1 to 3 , and the structure of the first hanging piece 1 is shown in Figures 4 to 6 , and the structure of the second hanging piece 2 is shown in Figure 7 and Figure 8 . Among them, as one preferred embodiment, the structure of the first hanging piece 1 and the second hanging piece 2 of the embodiment is substantially the same and substantially hexagonal, and the end of the first hanging piece 1 away from the second hanging piece 2 is tapered with gradually decreasing cross section, and the end of the second hanging piece 2 away from the first hanging piece 1 is tapered with gradually decreasing cross section. Such design not only makes the first hanging piece 1 and the second hanging piece 2 have better aesthetics, but also flexibly avoids other surrounding components, successfully completes the installation in limited space, and enhances the universality and adaptability of the hanging structure on various vehicle platforms.

[0052] In addition, in combination with Figures 1 to 3As shown in the drawings, as a specific embodiment, the first hanger 1 of the present embodiment is used to be connected with the vehicle body, and the second hanger 2 is used to be connected with the exhaust system. Moreover, the first hanger 1 is provided with a first through hole 1011 connected with the vehicle body, and a first hollow hole 1012 located on the side of the first hanger 1 close to the second hanger 2. Through the first through hole 1011, the commonly used hooks and the like connected with the vehicle body in the prior art can be matched, which is convenient for design implementation. The first hollow hole 1012 not only plays a role in reducing weight, but also facilitates heat dissipation of the first hanger 1 and improves its elasticity.

[0053] Moreover, as shown in the drawings, Figure 4 and Figure 5 As a preferred embodiment, in the use state, the first hollow hole 1012 is located below the first through hole 1011 based on the orientation of the whole vehicle, and is a long hole extending along the length direction of the first hanger 1. As shown in the drawings, Figure 7 and Figure 8 In the present embodiment, the second hanger 2 is provided with a second through hole 2011 connected with the exhaust system, and a second hollow hole 2012 located on the side of the second hanger 2 close to the first hanger 1. Through the second through hole 2011, the connection with the exhaust system can be facilitated, and the second hollow hole 2012 not only plays a role in reducing weight, but also facilitates heat dissipation of the second hanger 2 and improves its elasticity.

[0054] It should be noted that, in addition to making the structures of the first hanger 1 and the second hanger 2 substantially the same and making their cross sections substantially hexagonal, the cross sections of the first hanger 1 and the second hanger 2 can also be set as rectangular or other shapes. In addition, the first hanger 1 and the second hanger 2 can also have different structural shapes respectively. For example, the second hanger 2 and the first hanger 1 are set as different shapes respectively, or the second hollow hole 2012 is not provided on the first hanger 1 or the second hanger 2. In addition, in addition to connecting the first hanger 1 with the vehicle body and connecting the second hanger 2 with the exhaust system, the first hanger 1 can also be connected with the exhaust system, and the first hanger 1 can be connected with the vehicle body.

[0055] Here, mainly take the first hanging piece 1 as an example to introduce its structure, as a preferred embodiment, the first hanging piece 1 of the embodiment has a connecting end inserted in the second hanging piece 2, and the connecting part includes a plurality of connecting holes 1021 arranged at intervals along the circumference of the connecting end, and a via hole 2021 provided on the second hanging piece 2 corresponding to the connecting hole 1021. By providing the first hanging piece 1 with a connecting end inserted in the second hanging piece 2, this nested design makes the connection between the two hanging pieces more compact and stable. Therefore, after the connecting end is inserted into the second hanging piece 2, the relative translation between the two hanging pieces can be better limited, which provides a good foundation for subsequent connection and fixation through the connecting hole 1021 and the via hole 2021, and helps to ensure that the entire hanging structure can withstand various forces from the exhaust system during vehicle operation and maintain the stability of the relative position.

[0056] In addition, the connecting part includes connecting holes 1021 and via holes 2021 arranged one by one corresponding to the connecting holes 1021, which not only has a simple structure, but also is easy to design and implement. At the same time, the design of multiple connecting holes 1021 also provides a certain degree of redundancy, so that even if a connecting hole 1021 or a via hole 2021 is slightly damaged or worn, the normal work of the hanging structure can still be ensured by switching to other connection positions, which can improve the durability of the hanging structure.

[0057] It should be noted that in addition to inserting the connecting end into the second hanging piece 2 and making the connecting assembly include connecting holes 1021 and via holes 2021, the connecting end can also be screwed into the second hanging piece 2, at which time the connecting assembly can include external threads provided on one of the first hanging piece 1 and the second hanging piece 2, and threaded holes provided on the other.

[0058] As a preferred embodiment, in combination with Figure 4 to Figure 6 As shown in the above embodiments, in the embodiment, the first hanging piece 1 includes a first body 101 having elasticity, and a connecting block 102 provided on the first body 101, and the connecting block 102 constitutes the connecting end. And the second hanging piece 2 includes a second body 201 having elasticity, and a connecting cylinder 202 provided on the second body 201, and the connecting block 102 is inserted into the connecting cylinder 202. By providing the first hanging piece 1 with a connecting block 102 and inserting the connecting block 102 into the connecting cylinder 202, not only can better radial positioning be provided, so that the first hanging piece 1 is not easy to shake or deviate after insertion, but also in the axial direction, a certain tension and pressure can be borne by the contact length of the connecting block 102 and the connecting cylinder 202.

[0059] And in practice, the first body 101 can be made of rubber, and the connecting block 102 is vulcanized with the first body 101. Meanwhile, the second body 201 is also made of rubber, and the connecting cylinder 202 is vulcanized with the second body 201. In this way, the first hanger 1 and the second hanger 2 can well absorb the impact force and convert it into elastic potential energy, avoiding the impact force being directly transmitted to the other rigid components of the vehicle body or the exhaust system, thereby protecting the exhaust system and its connecting parts from damage caused by excessive impact, and prolonging the service life of the entire exhaust system. Of course, in addition to vulcanizing the connecting block 102 with the first body 101 and the connecting cylinder 202 with the second body 201, the connecting block 102 can also be connected to the first body 101 in other conventional ways, and the connecting cylinder 202 can also be connected to the second body 201 in other ways.

[0060] Here, as a preferred embodiment, the cross section of the connecting block 102 of the present embodiment is a regular polygon, and the connecting cylinder 202 is adapted to the connecting block 102. In this way, when the regular polygon connecting block 102 is inserted into the adapted connecting cylinder 202, it can be well positioned circumferentially due to its edge and corner characteristics. Unlike a circular connecting block 102, it will not rotate randomly in the connecting cylinder 202, preventing unnecessary angle changes due to torsional forces, which helps to ensure the stability of the exhaust system relative to the vehicle body, thereby improving the reliability of the entire hanger structure. In addition, for assembly workers, the shape of the regular polygon connecting block 102 is self-evident, making it easy to quickly identify the installation direction and position, which helps to improve the efficiency of assembly, adjustment, and maintenance work.

[0061] As shown in Figure 4 , as a preferred embodiment, the connecting block 102 of the present embodiment is hollow inside, and the cross section of the connecting block 102 is a square, and the connecting hole 1021 is disposed through the connecting block 102. In this way, the weight of the connecting block 102 can be effectively reduced, the material cost can be reduced, the structure is simple, and it is easy to design and implement, and it can also meet the general needs of angle adjustment. Correspondingly, the connecting block 102 of the present embodiment is provided with connecting holes 1021 on each side wall, and the cross section of the connecting cylinder 202 is also a square, and the via hole 2021 is provided on each side wall.

[0062] And here, it should be noted that in addition to setting the cross section of the connecting block 102 to be a square, it can also be set to other regular polygons. Alternatively, the connecting block 102 and the connecting cylinder 202 can both be circular, so that the hanger structure of the present embodiment has a larger angle adjustment range.

[0063] In addition, as a preferred embodiment, as shown in Figures 1 to 3As shown in the figure, the connecting assembly of the embodiment comprises a fixing pin 3 arranged through the connecting end, and an open pin 4 inserted on the fixing pin 3. As the fixing pin 3 is the main connecting component, it has high strength and rigidity and can bear large load. The fixing pin 3 can effectively transmit and disperse external force between the first hanging piece 1 and the second hanging piece 2, so as to ensure that the hanging structure will not be loosened or broken due to stress, and ensure the stable connection of the exhaust system relative to the vehicle body. In addition, during assembly, the worker only needs to align the fixing pin 3 with the hole position, and knock or push slightly to complete the insertion. Then, the open pin 4 is inserted and the opening part is bent, and the whole installation process does not need complex tools and special skills, and the assembly of the hanging structure can be quickly and efficiently completed, which is beneficial to improve the production efficiency.

[0064] It can be understood that, in addition to the fixing pin 3 and the open pin 4, the connecting assembly can also use bolts and nuts, and this structure can also realize the connection between the first hanging piece 1 and the second hanging piece 2, but this connection structure can reduce the efficiency.

[0065] Based on the above description, the exhaust system hanging structure of the embodiment can realize the free adjustment of the limiting direction. When the exhaust system needs to be replaced or repaired, the fixing pin 3 and the open pin 4 can be disassembled and assembled by using general tools, so that the disassembly and assembly can be quickly completed, the convenience of disassembly and assembly can be greatly improved, and the defects of the prior art that the hanging structure is not convenient to disassemble and is easy to be damaged can be effectively solved.

[0066] In addition, another object of the embodiment is to provide a vehicle provided with the above-mentioned exhaust system hanging structure.

[0067] The vehicle of the embodiment can improve the operation efficiency when the vehicle needs to be repaired or the exhaust system needs to be repaired or replaced by arranging the above-mentioned exhaust system hanging structure. The hanging structure has the characteristics of detachable connection and convenient adjustment of the limiting direction, and can improve the operation efficiency when the vehicle needs to be repaired or the exhaust system needs to be repaired or replaced.

[0068] The above description is only a preferred embodiment of the utility model, and does not limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
