[0023] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1 The vehicle described according to an embodiment of the present utility model includes: a frame 10 and an aftertreatment assembly 20.

[0024] Specifically, such as Figure 1 As shown, one end of the aftertreatment assembly 20 is connected to the frame 10, and the other end of the aftertreatment assembly 20 extends horizontally downward in a direction away from the frame 10.

[0025] The aftertreatment assembly 20 is detachably connected to the vehicle frame 10 at its higher end along the vehicle's height direction (hereinafter referred to as the second direction B). The other end of the aftertreatment assembly 20 extends along the first direction A and is inclined away from the vehicle frame 10 along the second direction B. In this embodiment, the aftertreatment assembly 20 can be an exhaust aftertreatment assembly 20.

[0026] According to the vehicle of this utility model embodiment, the layout of the aftertreatment assembly 20 is optimized by tilting the aftertreatment assembly 20, which can effectively reduce the height of the aftertreatment assembly 20 relative to the frame 10. For vehicles with a superstructure, this can reduce the space occupied by the aftertreatment assembly 20, increase the volume of the cargo box, and improve the space utilization above the aftertreatment assembly 20. At the same time, the tilting design of the aftertreatment assembly 20 in this application can meet the requirements of the vehicle's ground clearance, effectively improving the safety and reliability of the vehicle during driving.

[0027] According to some embodiments of this utility model, such as Figure 1As shown, the frame 10 extends along a first direction A and includes an upper wing surface 11 and a lower wing surface 12. The upper wing surface 11 and the lower wing surface 12 are disposed on both sides of the frame 10 along a second direction B, and the first direction A and the second direction B are perpendicular. One end of the aftertreatment assembly 20 is disposed between the upper wing surface 11 and the lower wing surface 12. Wherein, the first direction A is the longitudinal direction of the vehicle, and the second direction B is the vertical direction of the vehicle.

[0028] The frame 10 has an upper wing surface 11 and a lower wing surface 12 formed on both sides along the second direction B, with the upper wing surface 11 being higher than the lower wing surface 12. The end of the aftertreatment assembly 20 that is detachably connected to the frame 10 is located between the upper wing surface 11 and the lower wing surface 12 and is adjacent to the upper wing surface 11. The other end of the aftertreatment assembly 20 extends horizontally towards the lower wing surface 12.

[0029] Therefore, by placing one end of the aftertreatment assembly 20 between the upper wing surface 11 and the lower wing surface 12, the height of the aftertreatment assembly 20 can be avoided from being higher than the upper wing surface 11 of the frame 10, thereby improving the space utilization above the aftertreatment assembly 20, reducing the risk of the aftertreatment assembly 20 colliding with other vehicle components, avoiding interference with the installation of other components, and improving the safety and reliability of the vehicle.

[0030] Optionally, one end of the aftertreatment assembly 20 is located on the side of the lower wing 12 away from the upper wing 11. That is, the aftertreatment assembly 20 is connected to the frame 10 along the second direction B on the side of the lower wing 12 away from the upper wing 11, which can further increase the utilization of the interior space of the frame 10.

[0031] According to some embodiments of this utility model, such as Figure 1 As shown, the direction of the inclined extension of the post-processing assembly 20 forms an angle α with the upper wing surface 11, where α satisfies: 0 < α < 90°.

[0032] The angle formed between the inclined extension direction of the aftertreatment assembly 20 and the upper wing surface 11 can be set according to specific circumstances. When the angle formed between the inclined extension direction of the aftertreatment assembly 20 and the upper wing surface 11 is 90°, that is, the aftertreatment assembly 20 is set vertically, the aftertreatment assembly 20 is likely to be higher than the upper wing surface 11 of the frame 10, reducing the space utilization above the aftertreatment assembly 20. Furthermore, the vertical or straight setting of the aftertreatment assembly 20 can easily result in low ground clearance and poor vehicle passability.

[0033] Furthermore, α satisfies: 30° < α < 60°. Preferably, α = 45°.

[0034] Therefore, by limiting the angle range formed between the direction of the inclined extension of the aftertreatment assembly 20 and the upper wing surface 11, the height of the aftertreatment assembly 20 can be prevented from being higher than the upper wing surface 11 of the frame 10, thereby improving the space utilization above the aftertreatment assembly 20, reducing the risk of the aftertreatment assembly 20 colliding with other vehicle components, avoiding interference with the installation of other components, improving the safety and reliability of the vehicle, and enabling the vehicle to have good passability.

[0035] According to some embodiments of this utility model, such as Figure 1 As shown, the vehicle also includes a connecting bracket assembly 30, which is disposed between the aftertreatment assembly 20 and the frame 10, and the two ends of the connecting bracket assembly 30 are detachably connected to the aftertreatment assembly 20 and the frame 10, respectively.

[0036] The connecting bracket assembly 30 is adapted to connect the aftertreatment assembly 20 and the vehicle frame 10. One end of the connecting bracket assembly 30 adjacent to the vehicle frame 10 is detachably connected to the vehicle frame 10, and the other end of the connecting bracket away from the vehicle frame 10 is detachably connected to the aftertreatment assembly 20. In this embodiment, the connecting bracket assembly 30 is bolted to both the aftertreatment assembly 20 and the vehicle frame 10.

[0037] Therefore, by providing the connecting bracket assembly 30, with both ends of the connecting bracket assembly 30 detachably connected to the aftertreatment assembly 20 and the frame 10 respectively, the aftertreatment assembly 20 can be easily integrated onto the frame 10, improving the assembly and disassembly efficiency of the aftertreatment assembly 20 and enhancing the compactness and integration of the vehicle layout. Simultaneously, the connecting bracket assembly 30 increases the flexibility of installing the aftertreatment assembly 20 onto the frame 10.

[0038] According to some embodiments of this utility model, such as Figure 1 As shown, the connecting bracket assembly 30 includes: a first set of connecting brackets 31 and a second set of connecting brackets 34. One end of the first set of connecting brackets 31 is detachably connected to the vehicle frame 10; one end of the second set of connecting brackets 34 is detachably connected to the aftertreatment assembly 20; and the other end of the first set of connecting brackets 31 and the other end of the second set of connecting brackets 34 are detachably connected.

[0039] The first set of connecting brackets 31 is detachably connected to the frame 10 at one end adjacent to the upper wing surface 11 of the frame 10. The second set of connecting brackets 34 is detachably connected to the after-processing assembly 20 at one end adjacent to the after-processing assembly 20. The other end of the first set of connecting brackets 31 away from the upper wing surface 11 of the frame 10 is detachably connected to the other end of the second set of connecting brackets 34 away from the after-processing assembly 20. In this embodiment, the first set of connecting brackets 31 is first fixed to the frame 10, and the second set of connecting brackets 34 is connected to the first set of connecting brackets 31 after the after-processing assembly 20 is assembled.

[0040] Therefore, by setting the first set of connecting brackets 31 and the second set of connecting brackets 34, all the components on the aftertreatment assembly 20 are pre-assembled. Then, the second set of connecting brackets 34, which is assembled with the aftertreatment assembly 20, is connected to the first set of connecting brackets 31, thereby assembling the aftertreatment assembly 20 onto the frame 10. This improves the assembly efficiency of the aftertreatment assembly 20. At the same time, due to the separate design of the first set of connecting brackets 31 and the second set of connecting brackets 34, the maintenance and replacement of the connecting bracket assembly 30 can be facilitated.

[0041] Optionally, the first set of connecting brackets 31 and the second set of connecting brackets 34 are connected by bolts.

[0042] According to some embodiments of this utility model, such as Figure 1 As shown, the frame 10 includes an upper wing surface 11 and a lower wing surface 12. One end of the first set of connecting brackets 31 is located between the upper wing surface 11 and the lower wing surface 12, and the other end of the first set of connecting brackets 31 extends toward the lower wing surface 12 in a direction away from the upper wing surface 11.

[0043] The first set of connecting brackets 31 is located between the upper wing surface 11 and the lower wing surface 12. The first set of connecting brackets 31 is detachably connected to the upper wing surface 11 of the frame 10. The other end of the first set of connecting brackets 31 extends along the second direction B toward the lower wing surface 12 and is detachably connected to the second set of connecting brackets 34.

[0044] Therefore, by placing one end of the first set of connecting brackets 31 between the upper wing surface 11 and the lower wing surface 12, the installation height of the aftertreatment assembly 20 can be reduced, preventing the height of the aftertreatment assembly 20 from being higher than the upper wing surface 11 of the frame 10. The other end of the first set of connecting brackets 31 extends towards the lower wing surface 12 away from the upper wing surface 11, providing sufficient space for the installation of the second set of connecting brackets 34, avoiding interference between the first set of connecting brackets 31 and other structural components, thereby reducing the overall height of the aftertreatment assembly 20 and optimizing the installation structure of the aftertreatment assembly 20.

[0045] According to some embodiments of this utility model, such as Figure 1 As shown, the frame 10 includes an upper wing surface 11 and a lower wing surface 12. One end of the first set of connecting brackets 31 is located between the upper wing surface 11 and the lower wing surface 12, and the other end of the first set of connecting brackets 31 is located between the upper wing surface 11 and the lower wing surface 12 and extends toward the aftertreatment assembly 20.

[0046] The first set of connecting brackets 31 has one end adjacent to the upper wing surface 11 located between the upper wing surface 11 and the lower wing surface 12. The end of the first set of connecting brackets 31 adjacent to the upper wing surface 11 of the frame 10 is detachably connected to the frame 10. The other end of the first set of connecting brackets 31 is also located between the upper wing surface 11 and the lower wing surface 12. One end of the first set of connecting brackets 31 extends along a second direction B, and the other end extends along a third direction C. The second direction B and the third direction C are different. In this application, the third direction C is the left-right direction of the vehicle. In this case, the other end of the first set of connecting brackets 31 bends and extends along the third direction C toward the aftertreatment assembly 20, and forms a detachable connection with the second set of connecting brackets 34.

[0047] Therefore, by setting the other end of the first set of connecting brackets 31 between the upper wing surface 11 and the lower wing surface 12 and extending towards the post-processing assembly 20, it is easy to integrate the second set of connecting brackets 34 with the other end of the first set of connecting brackets 31, reduce assembly difficulty, improve assembly efficiency, optimize the position of the first set of connecting brackets 31 and the second set of connecting brackets 34, and ensure the installation height of the post-processing assembly 20.

[0048] According to some embodiments of this utility model, such as Figure 1 As shown, the first set of connecting brackets 31 includes a first bracket 32 ​​and a second bracket 33, which are spaced apart. One end of the first bracket 32 ​​and one end of the second bracket 33 are detachably connected to the vehicle frame 10, respectively. The second set of connecting brackets 34 includes a third bracket 35 and a fourth bracket 36, which are spaced apart. One end of the third bracket 35 and one end of the fourth bracket 36 are detachably connected to the aftertreatment assembly 20, respectively. The other end of the first bracket 32 ​​and the other end of the second bracket 33 are detachably connected to the other end of the third bracket 35 and the other end of the fourth bracket 36, respectively.

[0049] The first bracket 32 ​​and the second bracket 33 are spaced apart along the first direction A. One end of the first bracket 32 ​​is located between the upper wing surface 11 and the lower wing surface 12, and the other end of the first bracket 32 ​​is located between the upper wing surface 11 and the lower wing surface 12 and extends toward the post-processing assembly 20. One end of the second bracket 33 is located between the upper wing surface 11 and the lower wing surface 12, and the other end of the second bracket 33 extends toward the lower wing surface 12 away from the upper wing surface 11. The third bracket 35 is located between the first bracket 32 ​​and the post-processing assembly 20, and both ends of the third bracket 35 are detachably connected to the first bracket 32 ​​and the post-processing assembly 20, respectively. The fourth bracket 36 is located between the second bracket 33 and the post-processing assembly 20, and both ends of the fourth bracket 36 are detachably connected to the second bracket 33 and the post-processing assembly 20, respectively.

[0050] Therefore, by detachably connecting the first bracket 32 ​​and the third bracket 35, and by detachably connecting the second bracket 33 and the fourth bracket 36, the assembly and disassembly efficiency between the first set of connecting brackets 31 and the second set of connecting brackets 34 can be effectively improved, thereby improving the overall assembly efficiency of the vehicle, reducing costs, and improving the integration and compactness of the vehicle.

[0051] According to some embodiments of the present invention, the first bracket 32 ​​includes a first mounting portion and a second mounting portion, or the second bracket 33 includes a first mounting portion and a second mounting portion, or both the first bracket 32 ​​and the second bracket 33 include a first mounting portion and a second mounting portion. One end of the first mounting portion and one end of the second mounting portion are connected. The other end of the first mounting portion extends along the second direction B and is connected to the frame 10. The other end of the second mounting portion extends along the third direction C and is detachably connected to the second set of connecting brackets 34. The second direction B intersects with the third direction C.

[0052] In this embodiment, the first mounting part is located at one end of the first bracket 32 ​​and the second bracket 33 along the second direction B near the upper wing surface 11 of the frame 10, and the first bracket 32 ​​and the second bracket 33 are detachably connected to the frame 10 through the first mounting part. The second mounting part is located at one end of the first bracket 32 ​​and the second bracket 33 along the third direction C near the second set of connecting brackets 34, and the first bracket 32 ​​and the second bracket 33 are detachably connected to the second set of connecting brackets 34 through the second mounting part.

[0053] Therefore, by setting the first mounting part and the second mounting part, the first bracket 32 ​​and the second bracket 33 can be detachably connected to the frame 10 and the second set of connecting brackets 34, reducing the cost of repairing and replacing a single bracket, avoiding the aftertreatment assembly 20 occupying the space above the frame 10, while ensuring the installation height of the aftertreatment assembly 20, increasing the ground clearance of the vehicle, and improving the integration and compactness of the vehicle.

[0054] According to some embodiments of the present invention, the connecting bracket assembly 30 is at least partially constructed as a leaf spring bracket.

[0055] In this embodiment, the first bracket 32 ​​is a leaf spring bracket. The first mounting portion is connected to the vehicle frame 10, and the second mounting portion is adapted to connect to the aftertreatment assembly 20. Simultaneously, the first mounting portion is adapted to mount the suspension leaf spring. Therefore, the connecting bracket assembly 30 is at least partially constructed as a leaf spring bracket, which improves the structural strength of the connecting bracket assembly 30, facilitates the simultaneous mounting of the aftertreatment assembly 20 and the suspension leaf spring, improves the vehicle's integration, and allows for lightweight design. Furthermore, due to the simpler structure of the leaf spring bracket, the reliability and stability of the aftertreatment assembly 20 assembly are improved, reducing production costs.
