Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a front bracket assembly and a vehicle. Background Technology

[0002] In cases where the aftertreatment assembly is arranged at an angle, and given that the tolerances of the aftertreatment assembly are generally quite large, the bracket of the aftertreatment assembly is directly connected to the vehicle frame. When the bracket and the aftertreatment assembly are assembled and then connected to the vehicle frame, it can lead to problems such as inability to position or adjust, difficulty in assembly, and may also cause issues such as the bracket bolts not being able to be tightened because the wiring harness inside the vehicle frame has already been arranged.

[0003] When the bracket is first assembled onto the vehicle frame and then the angled aftertreatment assembly is assembled, the clearance between the front side of the aftertreatment assembly and the ground is relatively small due to the forward tilt of the aftertreatment assembly. This results in limited operating space and difficulty in tightening the front bracket and the aftertreatment assembly. Utility Model Content

[0025] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0026] The following is for reference. Figures 1-3 The description of the front bracket assembly 10 according to an embodiment of the present invention also proposes a vehicle including the aforementioned front bracket assembly 10.

[0027] Combination Figures 1-3 As shown, the front bracket assembly 10 is used to fix the aftertreatment assembly 40. The front bracket assembly 10 includes a first bracket 11 and a second bracket 12. The first bracket 11 can be connected to the leaf spring bracket 20 on the frame 30. The first bracket 11 and the second bracket 12 are connected to each other. The second bracket 12 is connected to the aftertreatment assembly 40, thereby mounting the aftertreatment assembly 40 on the frame 30 and fixing the aftertreatment assembly 40.

[0028] The first bracket 11 extends along the width direction of the vehicle, and one end of the first bracket 11 is adapted to connect with the leaf spring bracket 20 on the frame 30. Specifically, the leaf spring bracket 20 is connected to the frame 30, and the first bracket 11 extends from the frame 30 toward the inside of the vehicle, that is, the first bracket 11 extends along the width direction of the vehicle, and one end of the first bracket 11 can be connected to the leaf spring bracket 20 on the frame 30. Thus, the first bracket 11 can be connected to the leaf spring bracket 20 first.

[0029] The second bracket 12 extends along the length of the vehicle. One end of the second bracket 12 is detachably connected to the other end of the first bracket 11, and the other end is adapted to be connected to the front side of the aftertreatment assembly 40. Specifically, the second bracket 12 is connected to the front side of the aftertreatment assembly 40, the second bracket 12 extends in the length direction, one end of the second bracket 12 is detachably connected to the other end of the first bracket 11, and the other end of the second bracket 12 can be connected to the front side of the aftertreatment assembly 40.

[0030] Specifically, during the assembly process, the assembly is first performed by connecting the first bracket 11 to the leaf spring bracket 20. The second bracket 12 can be installed on the post-processing assembly 40. When installing the post-processing assembly 40, the post-processing assembly 40 and the second bracket 12 can be directly placed on the first bracket 11 to complete the assembly.

[0031] Thus, the second bracket 12 is connected to the leaf spring bracket 20 on the frame 30, and the aftertreatment assembly 40 is connected to the second bracket 12. After assembly, the second bracket 12 is then mounted on the first bracket 11, facilitating the installation of the angled aftertreatment assembly 40. The front bracket assembly 10 has a simple and flexible structure, can adapt to different aftertreatment assemblies 40, has strong versatility, and is extremely easy to assemble. Furthermore, the installation positions between the first bracket 11 and the second bracket 12, as well as the installation positions between the second bracket 12 and the aftertreatment assembly 40, can be adjusted according to the size or weight of the aftertreatment assembly 40.

[0032] according to Figure 2 and Figure 3 As shown, the first bracket 11 includes a first plate portion 111 and a second plate portion 112. The first plate portion 111 is connected to the leaf spring bracket 20, and the second plate portion 112 is located inside the first plate portion 111 and is connected to the second bracket 12. Specifically, the first plate portion 111 and the second plate portion 112 are arranged sequentially along the width direction of the vehicle. The first plate portion 111 is in contact with the leaf spring bracket 20 and can be detachably connected to the leaf spring bracket 20 for easy installation and removal. The second plate portion 112 is located inside the first plate portion 111 and extends inward to facilitate connection with the aftertreatment assembly 40. The second plate portion 112 is connected to the second bracket 12 mounted on the aftertreatment assembly 40.

[0033] According to 1- Figure 3 As shown, the second bracket 12 includes a third plate portion 121 and a fourth plate portion 122 connected to each other. The third plate portion 121 is connected to the second plate portion 112, and the fourth plate portion 122 is located on the rear side of the third plate portion 121 and is connected to the front side of the post-processing assembly 40. Specifically, the third plate portion 121 is detachably connected to the second plate portion 112, and the second bracket 12 is detachably connected to the first bracket 11. The fourth plate portion 122 is provided on the rear side of the second bracket 12. A portion of the fourth plate portion 122 is in contact with the post-processing assembly 40, and a portion of the fourth plate portion 122 transitions downward and backward in an arc shape to connect with the post-processing assembly 40.

[0034] like Figure 1 As shown, the fourth plate portion 122 includes an extension portion 1221 and a connecting portion 1222. One end of the extension portion 1221 is connected to the third plate portion 121, and the extension portion 1221 transitions downward and rearward in an arc shape. The connecting portion 1222 is connected to the other end of the extension portion 1221 and to the front side of the aftertreatment assembly 40. Specifically, the extension portion 1221 transitions downward and rearward in an arc shape, that is, the projection of the extension portion 1221 on the frame 30 is an arc segment, so that the connecting portion 1222 can fit snugly with the aftertreatment assembly 40. Furthermore, the tight fit between the connecting portion 1222 and the aftertreatment assembly 40 reduces the relative movement between the second bracket 12 and the aftertreatment assembly 40, reducing the risk of loosening or slippage due to vibration or other external forces. It also effectively absorbs and dissipates vibration energy, while reducing unnecessary shaking or swaying.

[0035] The first bracket 11 is provided with a first positioning part, and the second bracket 12 is provided with a second positioning part 123. The first positioning part and the second positioning part 123 are positioned and engaged.

The positioning holes are positioned and engaged to achieve positioning when the second bracket 12 is installed onto the first bracket 11, which facilitates the installation of the post-processing assembly 40 and improves assembly efficiency.

[0036] Furthermore, since the second plate portion 112 of the first bracket 11 is connected to the third plate portion 121 of the second bracket 12, the first positioning portion is disposed on the second plate portion 112 and the second positioning portion 123 is disposed on the third plate portion 121. The first positioning portion and the second positioning portion 123 are positioned and cooperated to realize the positioning cooperation between the second plate portion 112 and the third plate portion 121, that is, the positioning cooperation between the first bracket 11 and the second bracket 12.

[0037] like Figure 2As shown, at least one weight-reducing hole 13 is provided on the first support 11. That is, by providing a weight-reducing hole 13 on the first support 11, weight reduction is achieved without affecting the structural strength of the first support 11. There can be one weight-reducing hole 13, which can be located on the first plate portion 111, achieving weight reduction while maintaining the structural strength of the first support 11. Alternatively, there can be multiple weight-reducing holes 13, which are spaced apart on the first support 11, achieving weight reduction while maintaining the structural strength of the first support 11.

[0038] In some embodiments, the second support 12 is provided with at least one weight-reducing hole 13. Specifically, by providing the weight-reducing hole 13 on the second support 12, weight reduction is achieved without affecting the structural strength of the first support 11.

[0039] The weight-reducing hole 13 can be a single hole, located on the first plate portion 111, to reduce weight while maintaining the structural strength of the first support 11. Alternatively, there can be multiple weight-reducing holes 13, spaced apart on the first support 11, to reduce weight while maintaining the structural strength of the first support 11.

The first mounting portion 1111 can be a first mounting hole; the fifth mounting portion can be a fifth mounting hole. When the first bracket 11 is installed on the leaf spring bracket 20, the first mounting hole and the fifth mounting hole are first aligned, and then the first fastener passes through the first mounting hole and the fifth mounting hole to connect with the leaf spring bracket 20.

[0041] Furthermore, the front bracket assembly 10 also includes a second fastener. A second mounting portion 1121 is provided on the second plate portion 112, and a third mounting portion 1211 is provided on the third plate portion 121. The second fastener passes through the second mounting portion 1121 and the third mounting portion 1211 and is connected to the second bracket 12. Specifically, the first bracket 11 and the second bracket 12 are connected to the third plate portion 121 via the second plate portion 112, realizing a detachable connection between the first bracket 11 and the second bracket 12. The positions of the second mounting portion 1121 and the third mounting portion 1211 are corresponding. The second mounting portion 1121 can be a second mounting hole, and the third mounting portion 1211 can be a third mounting hole. The second fastener passes through the second mounting hole and the third mounting hole and is detachably connected to the second bracket 12, facilitating the installation and removal of the aftertreatment assembly 40.

[0042] There can be multiple second mounting parts 1121 and multiple third mounting parts 1211. Each of the multiple third mounting parts 1211 corresponds to one of the multiple second mounting parts 1121. The multiple second mounting parts 1121 are spaced apart along the width direction of the vehicle. There can be multiple second fasteners. The multiple second fasteners can pass through the multiple second mounting parts 1121 and the multiple third mounting parts 1211 respectively and connect to the second bracket 12 to ensure the connection strength of the first bracket and the second bracket 12 and ensure the installation reliability of the aftertreatment assembly 40.
