Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an exhaust hook mounting structure and a vehicle. Background Technology

[0002] As vehicle technology continues to advance, people's demands for vehicle comfort are increasing. Lower vehicle noise can effectively improve vehicle comfort and enhance the user experience. The exhaust system is one of the main sources of vibration and noise in vehicles. Vehicle noise and vibration problems caused by exhaust vibration are mainly due to two factors: firstly, the exhaust system itself generates significant excitation; secondly, the exhaust hook vibration is insufficiently damped. Poor vibration damping of the exhaust hook will transmit exhaust vibration to the vehicle body mounting point, thereby causing vehicle body vibration and resulting in vibration or noise problems in the cab. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides an exhaust hook mounting structure and a vehicle.

[0004] The first aspect of this application provides an exhaust hook mounting structure, including:

[0005] Vehicle body longitudinal beams;

[0006] Exhaust hook, installed on the longitudinal beam of the vehicle body;

[0007] A reinforcing member is provided in the internal area of ​​the vehicle body longitudinal beam and corresponds to the position of the exhaust hook on the vehicle body longitudinal beam. The reinforcing member includes a base plate and two side plates connected to the two opposite edges of the base plate. The base plate and the two side plates are constructed into an arched structure. The base plate and the two side plates are fixedly connected to the vehicle body longitudinal beam.

[0008] The exhaust hook mounting structure provided in this application has the exhaust hook mounted on the vehicle body longitudinal beam, which is a large frame structure of the vehicle body. This utilizes the strength of the longitudinal beam to reduce the vibration response sensitivity transmitted from the exhaust to the exhaust hook mounting position. A reinforcing member is provided inside the longitudinal beam, with its position corresponding to the position of the exhaust hook on the longitudinal beam. This enhances the overall structural strength of the exhaust hook mounting position. Furthermore, the reinforcing member includes a base plate and two side plates connected to opposite edges of the base plate. The base plate and the two side plates form an arched structure, and are fixedly connected to the longitudinal beam. This utilizes the strength of the arched structure and the multi-faceted fixation of the reinforcing member to the longitudinal beam to further increase the overall structural strength of the exhaust hook mounting position. This design effectively attenuates the vibration energy transmitted from the exhaust to the exhaust hook mounting position, thereby reducing the transmission of exhaust vibration energy and consequently attenuating the vibration transmitted from the exhaust to the vehicle body. This reduces in-vehicle vibration noise and provides a quiet and comfortable driving space for the user.

[0009] Optionally, the vehicle body longitudinal beam includes a bottom wall and side walls respectively connected to both sides of the bottom wall, wherein the bottom wall and the two side walls are configured as a groove-shaped structure;

[0010] The reinforcing member is housed in the internal region of the channel structure. The bottom plate of the reinforcing member is welded to the bottom wall of the vehicle body longitudinal beam, and the two side plates of the reinforcing member are respectively welded to the two side walls of the vehicle body longitudinal beam.

[0011] The above-mentioned design allows the structural shape of the reinforcing component to be compatible with that of the longitudinal beam of the vehicle body, facilitating the welding connection between the base plate of the reinforcing component and the bottom wall of the longitudinal beam, as well as the welding connection between the two side plates of the reinforcing component and the two side walls of the longitudinal beam, thereby enabling multi-face welding connection between the reinforcing component and the longitudinal beam of the vehicle body. This, in turn, enhances the overall structural strength of the exhaust hook mounting position.

[0012] Optionally, the exhaust hook is mounted on the outer surface of the side of the vehicle body longitudinal beam and is disposed adjacent to one of the two side plates of the reinforcing member;

[0013] At least one recessed structure is provided on at least one of the two side plates of the reinforcing member that is adjacent to the exhaust hook.

[0014] With the above configuration, at least one recessed structure is provided on at least one side plate of the reinforcing member adjacent to the exhaust hook. Compared with a flat side plate, the stress distribution of the side plate can be changed by using the recessed structure, thereby improving the load-bearing capacity and deformation resistance of the side plate, thereby increasing the structural strength of the side plate, and thus increasing the overall structural strength of the exhaust hook installation position.

[0015] Optionally, on one of the side plates adjacent to the exhaust hook, the recessed structure is recessed in a direction away from the exhaust hook, and the position of the exhaust hook on the vehicle longitudinal beam corresponds at least partially to the inner and outer sides of one of the recessed structures.

[0016] With the above setup, the position of the exhaust hook on the longitudinal beam of the vehicle body is at least partially aligned with the inside and outside of a recessed structure. The recessed structure can better disperse stress and reduce local stress concentration, thereby making better use of the recessed structure to attenuate the vibration energy transmitted by the exhaust to this position, achieving a better vibration reduction and noise reduction effect.

[0017] Optionally, at least one weight-reducing hole is provided on the base plate of the reinforcing member.

[0018] With the above configuration, at least one weight-reducing hole is provided on the base plate of the reinforcing member, which can reduce the weight of the reinforcing member and save on the material cost of the reinforcing member.

[0019] Optionally, the exhaust hook has a first end and a second end, the first end of the exhaust hook is fixedly connected to the longitudinal beam of the vehicle body, and the first end of the exhaust hook is formed into a flattened structure.

[0020] With the above configuration, the end of the exhaust hook that is fixedly connected to the longitudinal beam of the vehicle body is set as a flattened structure. Compared with a cylindrical exhaust hook, this can increase the span and strength of the connection between the exhaust hook and the longitudinal beam of the vehicle body, thereby better attenuating the vibration energy transmitted by the exhaust to this position.

[0021] Optionally, the two sides of the flattened structure along the width direction are welded to the longitudinal beams of the vehicle body.

[0022] The above configuration allows the flattened structure to fit snugly against the longitudinal beams of the vehicle body, ensuring a large contact area between the exhaust hook and the longitudinal beams. Furthermore, the flattened structure is welded to the longitudinal beams on both sides along its width, ensuring a wide connection span between the flattened structure and the longitudinal beams, thereby enhancing the structural strength of the connection between the exhaust hook and the longitudinal beams.

[0023] Optionally, the vehicle body longitudinal beam has a channel-shaped structure with an open top, and the exhaust hook is installed on the outer surface of the side of the vehicle body longitudinal beam;

[0024] The top of the vehicle body longitudinal beam is connected to a sheet metal part, which has at least one recessed structure and / or at least one protruding structure.

[0025] With the above configuration, at least one recessed structure and / or at least one protruding structure are provided on the sheet metal part to increase the structural strength of the sheet metal part, thereby increasing the overall structural strength of the exhaust hook mounting position and reducing the vibration response sensitivity transmitted by the exhaust hook to that position.

[0026] Optionally, a connecting plate is connected to the sheet metal part, and the connecting plate is connected to the D-pillar of the vehicle body.

[0027] The above setup utilizes a connecting plate to connect the sheet metal parts and the D-pillar of the vehicle body, thereby further leveraging the structural strength of the D-pillar to increase the overall structural strength of the exhaust hook mounting location and reduce the vibration response sensitivity transmitted from the exhaust hook to that location.

[0028] A second aspect of this application provides a vehicle including an exhaust hook mounting structure as described in any of the preceding claims. Attached Figure Description

[0046] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0047] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0048] The exhaust hook installation structure and vehicle provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0049] Reference Figures 1 to 9 As shown, some embodiments of this application provide an exhaust hook mounting structure, including: a vehicle body longitudinal beam 1, an exhaust hook 2, and a reinforcing member 3.

[0050] The exhaust hook 2 is installed on the longitudinal beam 1 of the vehicle body; the reinforcing member 3 is located in the internal area of ​​the longitudinal beam 1 of the vehicle body and corresponds to the position of the exhaust hook 2 on the longitudinal beam 1 of the vehicle body. The reinforcing member 3 includes a base plate 31 and two side plates 32 that are respectively connected to the two opposite edges of the base plate 31. The base plate 31 and the two side plates 32 are constructed into an arched structure. The base plate 31 and the two side plates 32 are all fixedly connected to the longitudinal beam 1 of the vehicle body.

[0051] It should be understood that the exhaust hook 2 is used to securely fix the vehicle's exhaust pipe in a suitable position, thereby ensuring the stability of the exhaust pipe during vehicle operation. The body longitudinal beam 1 is the main frame structure of the vehicle body and plays an important load-bearing role. In this embodiment, by installing the exhaust hook 2 on the body longitudinal beam 1, the strength of the body longitudinal beam 1 can be used to reduce the vibration response sensitivity transmitted from the exhaust to the installation position of the exhaust hook 2, thereby effectively attenuating the vibration transmitted from the exhaust to the vehicle body and reducing vibration noise inside the vehicle.

[0052] Furthermore, the vehicle body longitudinal beam 1 is usually stamped from low alloy steel plate, and its cross-sectional shape is generally channel-shaped, Z-shaped, or box-shaped, thus forming an accommodating space in the internal area of ​​the vehicle body longitudinal beam 1. The exhaust hook 2 is usually installed on the outer surface of the vehicle body longitudinal beam 1. In this embodiment, a reinforcing member 3 is provided in the internal area of ​​the vehicle body longitudinal beam 1. That is, the reinforcing member 3 is provided in the accommodating space formed in the internal area of ​​the vehicle body longitudinal beam 1, and the position of the reinforcing member 3 in the internal area of ​​the vehicle body longitudinal beam 1 corresponds to the position of the exhaust hook 2 on the vehicle body longitudinal beam 1. In other words, a reinforcing member 3 is provided in the internal area of ​​the vehicle body longitudinal beam 1 at the position corresponding to the installation position of the exhaust hook 2. In this way, the reinforcing member 3 can be used to improve the overall structural strength of the installation position of the exhaust hook 2, thereby reducing the vibration response sensitivity of the exhaust transmitted to the installation position of the exhaust hook 2, thereby effectively attenuating the vibration transmitted from the exhaust to the vehicle body, and thus reducing the vibration noise inside the vehicle.

[0053] Furthermore, the reinforcing member 3 includes a base plate 31 and two side plates 32 connected to the two opposite edges of the base plate 31. The base plate 31 and the two side plates 32 are constructed into an arched structure, that is, the reinforcing member 3 as a whole is an arched structure, and the base plate 31 and the two side plates 32 are all fixedly connected to the vehicle longitudinal beam 1. That is, the three sides of the reinforcing member 3 are fixed to the vehicle longitudinal beam 1. In this way, the strength of the arched structure formed by the reinforcing member 3 and the multi-sided fixation of the reinforcing member 3 to the vehicle longitudinal beam 1 can be used to better increase the overall structural strength of the exhaust hook 2 installation position. With this setting, the vibration energy transmitted from the exhaust to the exhaust hook 2 installation position can be effectively attenuated, thereby reducing the transmission of exhaust vibration energy, and further attenuating the vibration transmitted from the exhaust to the vehicle body, thereby reducing the vibration noise in the vehicle and providing users with a quiet and comfortable driving space.

[0054] In some embodiments, refer to Figure 5 As shown, the vehicle body longitudinal beam 1 includes a bottom wall 11 and two side walls 12 connected to the two sides of the bottom wall 11 respectively. The bottom wall 11 and the two side walls 12 are constructed into a channel-shaped structure. The reinforcing member 3 is housed in the internal area of ​​the channel-shaped structure. The bottom plate 31 of the reinforcing member 3 is welded to the bottom wall 11 of the vehicle body longitudinal beam 1, and the two side plates 32 of the reinforcing member 3 are welded to the two side walls 12 of the vehicle body longitudinal beam 1 respectively.

[0055] In specific implementation, the structural shape of the reinforcing member 3 can be adapted to the structural shape of the vehicle longitudinal beam 1. Specifically, the shape of the arch structure formed by the bottom plate 31 and the two side plates 32 of the reinforcing member 3 can be adapted to the shape of the groove structure formed by the bottom wall 11 and the two side walls 12 of the vehicle longitudinal beam 1, so that the reinforcing member 3 can be accommodated in the internal area of ​​the groove structure. The bottom plate 31 of the reinforcing member 3 can be at least partially attached to the bottom wall 11 of the vehicle longitudinal beam 1, and the two side plates 32 of the reinforcing member 3 can be at least partially attached to the two side walls 12 of the vehicle longitudinal beam 1, so as to facilitate the welding connection between the bottom plate 31 of the reinforcing member 3 and the bottom wall 11 of the vehicle longitudinal beam 1, and the welding connection between the two side plates 32 of the reinforcing member 3 and the two side walls 12 of the vehicle longitudinal beam 1, thereby realizing the multi-face welding connection between the reinforcing member 3 and the vehicle longitudinal beam 1, and thus using the reinforcing member 3 to better improve the overall structural strength of the exhaust hook 2 installation position.

[0056] In a specific implementation, the exhaust hook 2 can be installed on the outer surface of one of the side walls 12 of the vehicle body longitudinal beam 1. That is, the outer surface of one of the side walls 12 of the vehicle body longitudinal beam 1 is formed as the hook mounting surface 13, and the exhaust hook 2 is installed on the hook mounting surface 13. Specifically, the exhaust hook 2 can be welded to the hook mounting surface 13.

[0057] Specifically, refer to Figure 6 As shown, the bottom plate 31 and the two side plates 32 of the reinforcing member 3 can both extend along the length direction of the longitudinal beam 1 of the vehicle body. That is, the length direction of the reinforcing member 3 can be consistent with the length direction of the longitudinal beam 1 of the vehicle body. This allows the bottom plate 31 of the reinforcing member 3 to be welded to the bottom wall 11 of the longitudinal beam 1 of the vehicle body at multiple points along the length direction, and the two side plates 32 of the reinforcing member 3 to be welded to the two side walls 12 of the longitudinal beam 1 of the vehicle body at multiple points along the length direction, thereby using the reinforcing member 3 to better improve the overall structural strength of the exhaust hook 2 installation position.

[0058] Reference Figure 1 , Figure 2 and Figure 5 As shown in the figure, the X direction indicates the length direction of the longitudinal beam 1 of the vehicle body, the Y direction indicates the width direction of the longitudinal beam 1 of the vehicle body, that is, the direction of the two side walls 12 of the longitudinal beam 1 of the vehicle body facing each other, and the Z direction indicates the height direction of the longitudinal beam 1 of the vehicle body.

[0059] In specific implementation, refer to Figure 6 As shown, the installation position of the exhaust hook 2 can correspond to the middle area of ​​the reinforcing member 3 along its length. This allows the reinforcing member 3 to better improve the overall structural strength of the installation position of the exhaust hook 2. The length of the reinforcing member 3 is not specifically limited and can be reasonably set according to actual conditions. For example, the length of the reinforcing member 3 can be 10cm, 15cm, 20cm, etc.

[0060] In some embodiments, refer to Figure 6 As shown, the exhaust hook 2 is installed on the outer surface of the side of the longitudinal beam 1 of the vehicle body and is disposed adjacent to one of the two side plates 32 of the reinforcing member 3; at least one recess structure 321 is provided on the side plate 32 adjacent to the exhaust hook 2 of the two side plates 32 of the reinforcing member 3.

[0061] It should be understood that the exhaust hook 2 is installed on the outer surface of the side of the body longitudinal beam 1, that is, the exhaust hook 2 is installed on the outer surface of one of the two side walls 12 of the body longitudinal beam 1, or in other words, the exhaust hook 2 is installed on the surface of one side wall 12 of the body longitudinal beam 1 that is away from the other side wall 12.

[0062] In a specific implementation, the two side plates 32 of the reinforcing member 3 can be fixedly connected to the two opposite side walls 12 of the vehicle body longitudinal beam 1, while the exhaust hook 2 is installed on the outer surface of one side wall 12 of the vehicle body longitudinal beam 1, so that the exhaust hook 2 and one side plate 32 of the reinforcing member 3 are arranged close to each other, with the side wall 12 of the vehicle body longitudinal beam 1 between them.

[0063] By providing at least one recessed structure 321 on at least one side plate 32 of the reinforcing member 3 adjacent to the exhaust hook 2, that is, at least one recessed structure 321 can be provided only on one side plate 32 of the reinforcing member 3 adjacent to the exhaust hook 2, or at least one recessed structure 321 can be provided on both side plates 32 of the reinforcing member 3. Compared with a flat side plate 32, the stress distribution of the side plate 32 can be changed by using the recessed structure 321, thereby improving the load-bearing capacity and deformation resistance of the side plate 32, thereby increasing the structural strength of the side plate 32, and thus increasing the overall structural strength of the exhaust hook 2 installation position.

[0064] In specific implementations, the number of recessed structures 321 can be one or more. When the number of recessed structures 321 is multiple, the multiple recessed structures 321 can be spaced apart along the length direction of the reinforcing member 3. For example, refer to... Figure 6 As shown, there are three recessed structures 321, and the three recessed structures 321 are spaced apart along the length direction of the reinforcing member 3.

[0065] It should be understood that when both side plates 32 of the reinforcing member 3 are provided with recessed structures 321, the recessed structures 321 on the two side plates 32 can be arranged one-to-one. This arrangement achieves structural symmetry of the reinforcing member 3, thereby better improving the structural strength of the reinforcing member 3. Of course, the recessed structures 321 on the two side plates 32 can also be staggered.

[0066] In some embodiments, refer to Figure 6As shown, on one side panel 32 adjacent to the exhaust hook 2, the recessed structure 321 is recessed in a direction away from the exhaust hook 2, or in other words, the recessed structure 321 is recessed towards the inner area of ​​the arched structure formed by the reinforcing member 3. The position of the exhaust hook 2 on the longitudinal beam 1 of the vehicle body corresponds at least partially to one of the recessed structures 321. That is, the exhaust hook 2 is at least partially opposite to one of the recessed structures 321, specifically opposite to the two side walls 12 of the longitudinal beam 1 of the vehicle body in opposite directions (as shown in the Y direction in the figure).

[0067] This design allows for better stress dispersion through the recessed structure 321, reducing local stress concentration and thus better utilizing the recessed structure 321 to attenuate the vibration energy transmitted from the exhaust to that location, achieving a better vibration reduction and noise reduction effect.

[0068] Of course, in specific implementations, the exhaust hook 2 is not limited to being at least partially opposite one of the recessed structures 321, but can also be staggered from the recessed structure 321. For example, the exhaust hook 2 can also be located in the area between two adjacent recessed structures 321.

[0069] The shape of the recess structure 321 can be configured as an arched recess, that is, the longitudinal section of the recess structure 321 along its depth direction is arched. For example, referring to... Figure 6 As shown, the arched recess is recessed in the direction away from the exhaust hook 2, and extends along the height direction of the side plate 32, penetrating the top and bottom surfaces of the side plate 32. This design utilizes the strength of the arched recess to better enhance the structural strength of the reinforcing member 3, thereby improving the overall structural strength of the exhaust hook 2 installation location.

[0070] In some embodiments, refer to Figure 6 As shown, the side plate 32 of the reinforcing member 3 near the exhaust hook 2 is provided with multiple recessed structures 321. These recessed structures 321 are spaced apart along the length of the side plate 32 of the reinforcing member 3, and extend along the height of the side plate 32, penetrating both the top and bottom surfaces of the side plate 32. This arrangement creates an alternating concave-convex structure on the side plate 32 of the reinforcing member 3 along its length, which helps to improve the overall structural strength of the side plate 32 of the reinforcing member 3.

[0071] For example, the side plate 32 of the reinforcing member 3 near the exhaust hook 2 is provided with three recessed structures 321, which are spaced apart along the length of the reinforcing member 3. The exhaust hook 32 is at least partially opposite to the middle recessed structure 321 of the three recessed structures 321.

[0072] It should be noted that multiple recessed structures 321 may also be provided on the side plate 32 of the reinforcing member 3 away from the exhaust hook 2. The multiple recessed structures 321 are spaced apart along the length direction of the side plate 32 of the reinforcing member 3, and the multiple recessed structures 321 extend along the height direction of the side plate 32 of the reinforcing member 3 and penetrate the top and bottom surfaces of the side plate 32.

[0073] In specific implementation, the recessed structures 321 on the two side plates 32 of the reinforcing member 3 can correspond one to one and be symmetrically arranged to better improve the overall structural strength of the reinforcing member 3.

[0074] It should be noted that the reinforcing member 3 can be made of metal, and the recessed structure 321 on the reinforcing member 3 can be formed by stamping.

[0075] In some embodiments, refer to Figure 6 As shown, at least one weight-reducing hole 311 is provided on the base plate 31 of the reinforcing member 3 to reduce the weight of the reinforcing member 3 and save on material costs. The number of weight-reducing holes 311 is not specifically limited and can be reasonably set according to actual needs. For example, refer to... Figure 6 As shown, the base plate 31 of the reinforcing member 3 is provided with seven weight reduction holes 311. The size and shape of the seven weight reduction holes 311 can be the same or different, and can be reasonably set according to the actual situation.

[0076] In some embodiments, refer to Figure 8 and Figure 9 As shown, the exhaust hook 2 has a first end and a second end. The first end of the exhaust hook 2 is fixedly connected to the longitudinal beam 1 of the vehicle body, and the first end of the exhaust hook 2 is formed into a flattened structure 21. This configuration, compared to a cylindrical exhaust hook 2, increases the connection span and strength between the exhaust hook 2 and the longitudinal beam 1 of the vehicle body, thereby better attenuating the vibration energy transmitted from the exhaust to that location.

[0077] In specific implementation, refer to Figure 9 As shown, the first end of the exhaust hook 2, that is, the position where the exhaust hook 2 connects to the longitudinal beam 1 of the vehicle body, can be stamped to form a fan-shaped flattened structure 21. That is, the end area of ​​the first end of the exhaust hook 2 is formed into a flattened structure 21, while the part of the first end of the exhaust hook 2 near the second end can be formed into a fan-shaped transition structure that is gradually flattened (that is, the thickness gradually changes). This can better ensure the structural strength of the exhaust hook 2.

[0078] In some embodiments, refer to Figure 9As shown, the flattened structure 21 is welded to the longitudinal beam 1 of the vehicle body on both sides along the width direction. This arrangement ensures that the large surface of the flattened structure 21 fits snugly against the longitudinal beam 1 of the vehicle body, thereby ensuring a large contact area between the exhaust hook 2 and the longitudinal beam 1 of the vehicle body. Furthermore, the welding of the flattened structure 21 to the longitudinal beam 1 on both sides along the width direction ensures a wide connection span between the flattened structure 21 and the longitudinal beam 1 of the vehicle body, thus enhancing the structural strength of the connection between the exhaust hook 2 and the longitudinal beam 1 of the vehicle body.

[0079] In specific implementation, refer to Figure 9 As shown, the exhaust hook 2 can be bent as needed. For example, the exhaust hook 2 has a first end and a second end. The first end of the exhaust hook 2 is bent relative to the second end to form a bending portion 23 between the first end and the second end of the exhaust hook 2. Specifically, the first end of the exhaust hook 2 can be a flattened structure 21, and the second end of the exhaust hook 2 can be a cylindrical structure 22. A bending portion 23 is connected between the flattened structure 21 and the cylindrical structure 22. The side surface of the flattened structure 21 facing away from the cylindrical structure 22 is attached to the surface of the vehicle longitudinal beam 1, and the two sides of the flattened structure 21 along the width direction are welded to the vehicle longitudinal beam 1 to form a welded portion 24 on each side of the flattened structure 21 along the width direction.

[0080] In some embodiments, refer to Figure 1 , Figure 2 and Figure 4 As shown, the body longitudinal beam 1 has a channel-shaped structure with an open top, and the exhaust hook 2 is installed on the outer surface of the side of the body longitudinal beam 1; the top of the body longitudinal beam 1 is connected to a sheet metal part 4. Specifically, the sheet metal part 4 can be welded to the body longitudinal beam 1, and the sheet metal part 4 can at least partially cover the top opening of the body longitudinal beam 1, so as to increase the overall structural strength of the body longitudinal beam 1 by using the sheet metal part 4.

[0081] In some embodiments, refer to Figure 7 As shown, the sheet metal part 4 is provided with at least one recessed structure 41 and / or at least one protruding structure 42. This arrangement increases the structural strength of the sheet metal part 4, thereby increasing the overall structural strength of the mounting position of the exhaust hook 2 and reducing the vibration response sensitivity transmitted by the exhaust hook 2 to that position.

[0082] It should be understood that, in order to achieve a structural reinforcement effect on the hook mounting position, the recessed structure 41 and / or protruding structure 42 provided on the sheet metal part 4 can be set relatively close to the exhaust hook 2. In specific implementations, the number of recessed structures 41 and protruding structures 42 is not limited to one, and multiple can be provided as needed. The shape of recessed structures 41 and protruding structures 42 is not limited to circular, but can also be trapezoidal, rectangular, or other shapes.

[0083] For example, the sheet metal part 4 above the longitudinal beam 1 of the vehicle body at the installation position of the exhaust hook 2 is provided with three circular recesses (or circular pits), one circular protrusion (or circular bulge) and one trapezoidal recess (or trapezoidal pit) to form a reinforcing structure.

[0084] In some embodiments, refer to Figure 7 As shown, a connecting plate 5 is connected to the sheet metal part 4, and the connecting plate 5 is connected to the D-pillar 6 of the vehicle body. That is to say, the connecting plate 5 is used to connect the sheet metal part 4 and the D-pillar 6 of the vehicle body, thereby further utilizing the structural strength of the D-pillar 6 to increase the overall structural strength of the exhaust hook 2 mounting position and reduce the vibration response sensitivity transmitted by the exhaust hook 2 to that position.

[0085] In practice, the connecting plate 5 can be welded to the sheet metal part 4, and the connecting plate 5 can be welded to the body D-pillar 6, thereby connecting the sheet metal part 4 and the body D-pillar 6 into one unit by using the connecting plate 5, thereby increasing the overall structural strength of the exhaust hook 2 installation position by utilizing the structural strength of the body D-pillar 6.

[0086] Other embodiments of this application provide a vehicle including an exhaust hook mounting structure as described in any of the above embodiments.

[0087] The vehicle provided in the above embodiments of this application has the beneficial effects of the exhaust hook mounting structure of any of the above embodiments because it includes the exhaust hook mounting structure of any of the above embodiments, which will not be described again here.
