Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts, and in particular to an exhaust system mounting structure. The utility model also relates to a subframe provided with the exhaust system mounting structure, and a vehicle provided with the subframe. Background Art

[0002] In existing vehicles, the exhaust hook is an important connecting component used to connect the exhaust system (including components such as exhaust lugs, exhaust pipes, etc.) with the subframe. It is generally L-shaped or curved, and has an anti-dropout limit structure at the end. However, the existing exhaust hook has a low modality. In order to increase the modality, the hook diameter is generally increased, which is not conducive to lightweighting. At the same time, only the anti-dropout limit is set at the end, which makes it difficult to control the movement of the exhaust lug, which will increase the safety and disaster prevention risks of the exhaust system. Utility Model Content

[0003] In view of this, the utility model aims to provide an exhaust system installation structure, which can reduce the safety and disaster prevention risks of the exhaust system.

[0004] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0005] An exhaust system mounting structure includes an exhaust hook disposed on a sub-frame;

[0006] The exhaust hook is bent into a sub-frame connecting section, a middle transition section and an exhaust hook mounting section which are connected in sequence;

[0007] The extension lines of the subframe connecting section and the exhaust hanging ear mounting section can intersect, and the angle formed between the extension lines of the two is between 40° and 50°;

[0008] A limiting structure is provided on the exhaust lifting ear mounting section, and an installation space is defined between the limiting structure and the anti-slip structure at the end of the exhaust lifting ear mounting section. The installation space is used to install the exhaust lifting ear, and the limiting structure and the anti-slip structure jointly constrain the exhaust lifting ear within the installation space.

[0009] Furthermore, the diameters of the subframe connecting section, the intermediate transition section and the exhaust hanger mounting section are the same.

[0010] Furthermore, the exhaust hook is horizontally arranged on the sub-frame, or the exhaust hook is nearly horizontally arranged on the sub-frame; and the exhaust lifting ear mounting section is arranged along the left-right direction of the vehicle.

[0011] Furthermore, the anti-slip structure includes an anti-slip boss arranged at the end of the exhaust lifting ear installation section, and the outer diameter of the anti-slip boss is gradually reduced in the direction away from the installation space.

[0012] Furthermore, the limiting structure includes a limiting protrusion provided on the outer peripheral wall of the exhaust lifting ear installation section, and the limiting protrusion is arranged in a circle circumferentially around the exhaust lifting ear installation section.

[0013] Furthermore, the anti-drop boss and the limiting protrusion are integrally formed on the exhaust lifting ear mounting section.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] The exhaust system mounting structure described in the utility model can increase the exhaust hook mode and avoid increasing the hook diameter through the three-section structure of the exhaust hook and the angle setting between the subframe connecting section and the exhaust ear mounting section, which is beneficial to its lightweight. At the same time, through the setting of the limiting structure, the exhaust ear is limited together with the anti-detachment structure at the end, and the movement of the exhaust ear can also be effectively limited, which is beneficial to reducing the safety and disaster prevention risks of the exhaust system and improving the safety of the entire vehicle.

[0016] Secondly, the diameters of each section of the exhaust hook are the same, which can facilitate the preparation of the exhaust hook. The exhaust hook is arranged horizontally, and the exhaust ear installation section is arranged along the left and right direction of the vehicle, which can better adapt to the front and back movement of the exhaust system and improve the safety of the exhaust system. The anti-slip structure adopts an anti-slip boss with a simple structure, so that the outer diameter of the anti-slip boss is gradually reduced, which can facilitate the installation of the exhaust ear. The limiting structure adopts a limiting protrusion with a simple structure, and the limiting protrusion is a circle, which can ensure the limiting effect on the exhaust ear. The anti-slip boss and the limiting protrusion are integrally formed on the exhaust ear installation section, which can facilitate the molding of the two, making the overall structure of the exhaust hook relatively simple, and can also ensure the stability of the anti-slip structure and the limiting structure.

[0017] In addition, another object of the present invention is to provide a sub-frame, on which the exhaust system mounting structure as described above is provided.

[0018] Furthermore, the sub-frame includes sub-frame longitudinal beams disposed on the left and right sides, and a first sub-frame cross beam connected between the sub-frame longitudinal beams on both sides; the exhaust hook is connected to the top of the first sub-frame cross beam.

[0019] Further, the sub-frame includes a second sub-frame cross beam connected between the sub-frame longitudinal beams on both sides, an anti-collision bracket is provided on the second sub-frame cross beam, and the anti-collision bracket is arranged close to the sub-frame longitudinal beams on one side; and / or, the sub-frame longitudinal beams on both sides include a longitudinal beam front section and a longitudinal beam rear section welded together, and in the left and right directions of the whole vehicle, an offset collision bracket is provided on the side of the front end of the sub-frame longitudinal beams on both sides facing the outside of the vehicle.

[0020] In addition, another object of the present invention is to provide a vehicle, wherein the above-mentioned subframe is provided in the vehicle.

[0021] The subframe and the vehicle described in the utility model are provided with the above-mentioned exhaust system installation structure, which can not only prevent the exhaust lifting ear from moving and reduce the safety and disaster prevention risks of the exhaust system, but also facilitate the lightweight design of the entire vehicle, thereby improving the quality of the entire vehicle.

[0022] At the same time, the exhaust hook is connected to the top of the subframe crossbeam, which can provide a larger layout space for the exhaust hook, which is conducive to the layout of the exhaust system installation structure. The anti-collision bracket can increase the head-on collision performance of the subframe, which is conducive to the conduction of head-on collision force. The subframe longitudinal beam is composed of front and rear sections welded together, which can facilitate the preparation of the subframe longitudinal beam and is also conducive to the collapse and energy absorption of the subframe longitudinal beam during collision. The offset collision bracket is set on the outside of the subframe longitudinal beam, which can increase the collision force conduction performance during offset collision and help improve the safety of offset collision.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] Embodiment 1

[0043] The present embodiment relates to an exhaust system installation structure, which can be beneficial for lightweighting, and at the same time, can also prevent the exhaust lifting lug 61 from moving, stabilize the movement of the exhaust system 6 when the whole vehicle is in motion, so as to reduce the safety and disaster prevention risks of the exhaust system 6.

[0044] In terms of overall structure, Figures 1 to 7 As shown, the exhaust system installation structure of this embodiment includes an exhaust hook 5 provided on the sub-frame. The exhaust hook 5 is bent into a sub-frame connecting section 51, an intermediate transition section 52 and an exhaust hanging ear installation section 53 which are sequentially connected. The extension lines of the sub-frame connecting section 51 and the exhaust hanging ear installation section 53 can intersect, and the angle β formed between the extension lines of the two is between 40° and 50°.

[0045] In addition, a limiting structure is provided on the exhaust lifting ear mounting section 53, and an installation space 56 is defined between the limiting structure and the anti-slip structure at the end of the exhaust lifting ear mounting section 53. The installation space 56 is used to install the exhaust lifting ear 61, and the limiting structure and the anti-slip structure jointly constrain the exhaust lifting ear 61 within the installation space 56.

[0046] At this time, as set above, based on the three-section structure of the exhaust hook 5 and the angle β between the subframe connecting section 51 and the exhaust ear mounting section 53, the exhaust hook 5 mode can be increased without adding a sub-hook, and the increase in the hook diameter can also be avoided, which is beneficial to its lightweight. At the same time, the joint limiting effect of the limiting structure and the anti-slip structure can also effectively limit the movement of the exhaust ear 61, thereby helping to reduce the safety and disaster prevention risks of the exhaust system 6.

[0047] Based on the above overall introduction, in detail, in this embodiment, in the specific implementation, the extension line of the subframe connecting section 51 is named as the extension line a511, and the extension line of the exhaust ear mounting section 53 is named as the extension line b531, so as to facilitate the illustration and introduction of the relevant content of the angle β.

[0048] At the same time, if Figure 4 As shown in , the angle β is formed between the extension line a511 and the extension line b531. The value of the angle β can be set and adjusted accordingly according to the actual modal requirements of the exhaust hanger 61. For example, the angle β can be specifically 40°, 45° or 50°.

[0049] In this embodiment, as a preferred implementation form, the diameters of the subframe connecting section 51 , the middle transition section 52 and the exhaust hanging ear mounting section 53 are the same to facilitate the preparation of the exhaust hanging hook 5 .

[0050] In addition, as a preferred embodiment, the exhaust hook 5 is arranged horizontally on the sub-frame, or the exhaust hook 5 is arranged nearly horizontally on the sub-frame, and the exhaust hook mounting section 53 is arranged along the left and right direction of the vehicle. In this way, the exhaust system 6 can be better adapted to the situation of front and rear movement, and the safety of the exhaust system 6 can be improved.

[0051] Of course, the approach to horizontality described in this embodiment means that there is a small inclination angle between the exhaust hook 5 and the horizontal plane, and the exhaust ear 61 is close to a horizontal state, and the specific value of the above-mentioned inclination angle can be, for example, less than 10°.

[0052] In addition, combined Figure 2 and Figure 5 As shown, in this embodiment, as a preferred implementation form, the anti-slip structure includes an anti-slip boss 55 arranged at the end of the exhaust ear mounting section 53, and the outer diameter of the anti-slip boss 55 is gradually reduced in the direction away from the mounting space 56.

[0053] The main advantage of such a configuration is that it not only has a simple structure, but also allows the outer diameter of the anti-slip boss 55 to be gradually reduced, which can also facilitate the installation of the exhaust lifting ear 61.

[0054] Furthermore, as a preferred implementation form, the limiting structure of this embodiment includes a limiting protrusion 54 provided on the outer peripheral wall of the exhaust lifting ear mounting section 53, and the limiting protrusion 54 is a circle arranged circumferentially around the exhaust lifting ear mounting section 53. Here, the limiting structure adopts the limiting protrusion 54, which has a simple structure, and the limiting protrusion 54 is a circle, which can ensure the limiting effect on the exhaust lifting ear 61.

[0055] In the specific implementation, in this embodiment, as a preferred implementation form, the anti-slip boss 55 and the limiting protrusion 54 are integrally formed on the exhaust hook mounting section 53. In this way, the molding of the two can be facilitated, the overall structure of the exhaust hook 5 is relatively simple, and the stability of the anti-slip structure and the limiting structure can be ensured.

[0056] The exhaust system installation structure of this embodiment can increase the mode of the exhaust hook 5 and avoid increasing the hook diameter through the three-section structure of the exhaust hook 5 and the angle β between the subframe connecting section 51 and the exhaust ear installation section 53, which is beneficial to its lightweight. At the same time, through the setting of the limiting structure, the exhaust ear 61 is limited together with the anti-detachment structure at the end, and the movement of the exhaust ear 61 can also be effectively limited, which is beneficial to reducing the safety and disaster prevention risks of the exhaust system 6 and improving the safety of the whole vehicle.

[0057] Embodiment 2

[0058] This embodiment relates to a subframe, on which the exhaust system mounting structure in the first embodiment is provided.

[0059] Furthermore, in this embodiment, as a preferred implementation form, Figure 1 and Figure 3 As shown in FIG. 1 , the subframe includes a subframe longitudinal beam 1 disposed on the left and right sides, and a first subframe cross beam 2 connected between the subframe longitudinal beams 1 on both sides. An exhaust hook 5 is connected to the top of the first subframe cross beam 2.

[0060] It can be understood that by connecting the exhaust hook 5 to the top of the first sub-frame cross beam 2, a larger arrangement space can be provided for the exhaust lifting ear 61, which is beneficial to the arrangement of the exhaust system mounting structure.

[0061] Furthermore, as a preferred implementation form, in this embodiment, the subframe includes a second subframe crossbeam 3 connected between the subframe longitudinal beams 1 on both sides, and an anti-collision bracket 7 is provided on the second subframe crossbeam 3, and the anti-collision bracket 7 is arranged close to one side of the subframe longitudinal beam 1. In this way, the frontal collision performance of the subframe is increased, which is beneficial to the transmission of the frontal collision force.

[0062] In specific implementation, the above-mentioned subframe is generally the front subframe in the vehicle. Correspondingly, the first subframe cross beam 2 is the rear subframe cross beam, and the second subframe cross beam 3 is the front subframe cross beam. At the same time, the above-mentioned anti-collision bracket 7 is preferably arranged close to the subframe longitudinal beam 1 on the main driving side, that is, the subframe longitudinal beam 1 on the left side.

[0063] At the same time, in this embodiment, as a preferred implementation form, still refer to Figure 3 As shown, the auxiliary frame longitudinal beams 1 on both sides include a longitudinal beam front section 11 and a longitudinal beam rear section 12 which are welded to each other, and in the left-right direction of the vehicle, an offset collision bracket 8 is provided on the side of the front end of the auxiliary frame longitudinal beams 1 on both sides facing the outside of the vehicle.

[0064] In this embodiment, the subframe longitudinal beam 1 is composed of front and rear sections welded together, which can facilitate the preparation of the subframe longitudinal beam 1 and is also beneficial to the crushing energy absorption of the subframe longitudinal beam 1 during a collision. An offset collision bracket 8 is arranged on the outer side of the subframe longitudinal beam 1 to increase the collision force conduction performance during an offset collision, which is beneficial to improving the safety of the offset collision.

[0065] It is worth mentioning that in this embodiment, in the specific implementation, the anti-collision bracket 7 can be Figure 6 As shown, it is formed by integrally bending a plate, and the cross section is generally U-shaped. The advantage of such a setting is that a buffer cavity can be formed between the second sub-frame cross beam 3, so as to improve the head-on collision performance of the sub-frame and the whole vehicle.

[0066] Furthermore, in this embodiment, the front ends of the left and right side auxiliary frame longitudinal beams 1 are both provided with anti-collision beam connecting plates 101. Figure 7 As shown, the offset collision bracket 8 can be roughly designed in a triangular shape when viewed from the upper and lower directions of the entire vehicle. Specifically, at this time, a right-angled side of the offset collision bracket 8 is connected to the side of the subframe longitudinal beam 1 on the same side, and the other right-angled side of the offset collision bracket 8 is connected to the anti-collision beam connecting plate 101 on the same side, so as to utilize the high stability of the triangular structure to improve the collision force conduction performance.

[0067] Moreover, the above-mentioned offset collision bracket 8 can also be formed by integrally bending a plate and having a top plate and a bottom plate, and a side connecting plate connected between the top plate and the bottom plate. The advantage of such a setting is that a buffer cavity can be formed between the offset collision bracket 8 and the subframe longitudinal beam 1 on the same side and the anti-collision beam connecting plate 101 on the same side, thereby improving the collision performance.

[0068] Of course, the related structural parts not mentioned in the sub-frame of the present embodiment can all refer to the various structures in the sub-frame structure well known to those skilled in the art. For example, the sub-frame longitudinal beam 1 brackets on the left and right sides are also connected to the third sub-frame cross beam 4 located between the first sub-frame cross beam 2 and the second sub-frame cross beam 3, that is, the sub-frame middle cross beam, etc., which will not be described in detail here.

[0069] In addition, the present embodiment also relates to a vehicle, in which the above-mentioned subframe is provided. In specific implementation, the subframe is preferably a front subframe, and the left and right subframe longitudinal beams 1 of the subframe are both provided with a body connection bracket 9 for connecting with the same-side body longitudinal beam 100 of the vehicle.

[0070] The subframe and the vehicle of this embodiment, by providing the exhaust system installation structure in the first embodiment, can contribute to the lightweight of the whole vehicle, and at the same time, can also reduce the safety and disaster prevention risks of the exhaust system 6, thereby contributing to improving the quality and market competitiveness of the whole vehicle.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
