[0017] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will understand that modifications and variations can be made to the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.

[0018] This application provides a support assembly, including a first support 1 and a second support 2; like Figure 1As shown, the first bracket 1 is a long strip structure. The left end of the first bracket 1 is adapted to be connected to the front fender body 3, and the right end of the first bracket 1 is adapted to be connected to the rear suspension 4. The first bracket 1 is bent twice to form a first connecting part 11, a first bending part 12, and a second connecting part 13. The overall bending profile of the first bracket 1 has a Z-shaped longitudinal section. The first bracket 1 includes a first connecting part 11, a first bending part 12, and a second connecting part 13. The first connecting part 11 and the second connecting part 13 are connected by the first bending part 12 and are integrally formed. The first connecting part 11 and the second connecting part 13 are located in opposite directions of the first bending part 12. The first bending part 12 is located between the first connecting part 11 and the second connecting part 13, so that a first vertical height difference is formed between the first connecting part 11 and the second connecting part 13. Two first connecting holes 14 are opened on both the first connecting part 11 and the second connecting part 13. like Figure 2 As shown, the main view projection outline of the second bracket 2 is L-shaped. The left end of the second bracket 2 is adapted to connect with the front fender body 3, and the right end of the second bracket 2 is adapted to connect with the rear suspension 4. The first bracket 1 and the second bracket 2 are arranged at intervals along the length of the front fender body 3. The second bracket 2 includes a third connecting part 21, a second bending part 22, and a fourth connecting part 23. The width of the third connecting part 21 gradually increases from away from the second bending part 22 to near the second bending part 22, and the width of the fourth connecting part 23 gradually increases from away from the second bending part 22 to near the second bending part 22. The third connecting part 21 and the fourth connecting part 23 are connected by the second bending part 22 and are integrally formed. The third connecting part 21 and the fourth connecting part 23 are located in opposite directions of the second bending part 22, and the second bending part 22 is located at the third connecting part 21. Between the third connecting part 21 and the fourth connecting part 23, a second vertical height difference is formed between the third connecting part 21 and the fourth connecting part 23. The second vertical height difference is greater than the first vertical height difference. The reason why the second vertical height difference is greater than the second vertical height difference is that the distance between the front fender body 3 connected to the second bracket 2 and the rear suspension 4 is greater than the distance between the front fender body 3 connected to the first bracket 1 and the rear suspension 4. This is a setting to adapt to installation requirements. Two second connecting holes 24 are opened on both the third connecting part 21 and the fourth connecting part 23.

[0019] In another embodiment of this application, such as Figure 1 and Figure 2 As shown, the first support 1 has both sides of its width direction bent towards the same side to form a first flange 15, and the second support 2 has both sides of its width direction bent towards the same side to form a second flange 25. Both the first support 1 and the second support 2 have an anti-corrosion layer on their surfaces. This anti-corrosion layer is preferably black electrophoretic coating. The thickness of both the first support 1 and the second support 2 is 2-5 mm. In this embodiment, it is preferably 3 mm. Figure 1As shown, the first bent portion 12 is formed with a reinforcing rib 17 along its bending line direction. The corners of the reinforcing rib 17 are rounded, and the interior of the reinforcing rib 17 is hollow.

[0020] The first flange 15 enhances the overall strength of the first support 1 and improves its resistance to load stress deformation; the second flange 25 enhances the overall strength of the second support 2 and improves its resistance to load stress deformation. A thickness of 2mm for both the first and second supports is relatively thin, affecting their strength, while a thickness of 5mm is too thick, increasing their weight. Therefore, a thickness of 3mm is optimal. The electroplated anti-corrosion layer, with reinforcing ribs 17 formed by stamping, primarily strengthens the first bending portion 12, improving its resistance to deformation. Its hollow interior reduces weight. The black electrophoretic anti-corrosion layer, with a film thickness of 10-20 micrometers, exhibits strong adhesion and superior corrosion resistance compared to traditional paint spraying, providing a corrosion protection life of 10-20 years.

[0021] In another embodiment of this application, such as Figure 1 and Figure 2 As shown, the widths of the third connecting portion 21 and the fourth connecting portion 23 are both greater than the widths of the first connecting portion 11 and the second connecting portion 13.

[0022] The widths of the third connecting part 21 and the fourth connecting part 23 are larger than those of the first connecting part 11 and the second connecting part 13. This is mainly to adapt to the spatial installation environment of the front fender body 3 and the rear suspension 4. Furthermore, since the second bracket 2 spans a larger connection distance, a wider dimension is required to ensure its fixing strength and stress resistance.

[0023] In another embodiment of this application, such as Figure 1 and Figure 2 As shown, a first weight-reducing hole 16 is provided on the first connecting part 11. The first weight-reducing hole 16 is a rectangular elongated hole distributed along the length direction of the first connecting part 11. A second weight-reducing hole 26 is provided on the third connecting part 21. The second weight-reducing hole 26 is a quadrilateral hole with rounded corners. A third weight-reducing hole 27 is provided on the second bending part 22. The third weight-reducing hole 27 is also a quadrilateral hole with rounded corners.

[0024] The first weight reduction hole 16, the second weight reduction hole 26 and the third weight reduction hole 27 are designed not only to reduce the weight of the first bracket 1 and the second bracket 2, but also to avoid installation limitations caused by the structural parts intersecting with the structure on the front fender body 3 during installation.

[0025] like Figure 1As shown, the first connecting part 11 has two first connecting holes 14, which are respectively located at both ends of the length direction of the first connecting part 11. The length of the second connecting part 13 is less than the length of the first connecting part 11. The two first connecting holes 14 are respectively located at both ends of the length direction of the first connecting part 11 to ensure the overall connection strength between the first connecting part 11 and the front fender body 3, and to reduce the situation where the connection points are too concentrated. The length of the second connecting part 13 is less than the length of the first connecting part 11, mainly to adapt to the installation size requirements of the front fender body 3 and the rear suspension 4.

[0026] like Figure 2 As shown, the length of the third connecting part 21 is greater than the length of the fourth connecting part 23. The second connecting holes 24 on the third connecting part 21 are located at both ends of the length direction of the third connecting part 21, which mainly ensures the overall connection strength between the first connecting part 11 and the front fender body and reduces the situation of excessive concentration of connection points. A second weight reduction hole 26 is provided between the two second connecting holes 24 on the third connecting part 21. There are two second weight reduction holes 26 on the third connecting part 21. The two second weight reduction holes 26 are distributed to avoid affecting the overall strength of the third connecting part 21.

[0027] like Figure 3 As shown in the embodiments of this application, a front fender assembly is disclosed, comprising: Front fender body 3; the front fender body 3 is made of steel, preferably Q235. The rear suspension 4 is staggered with the front fender body 3; the top of the rear suspension 4 is connected to the fixed cab, and its structure is channel steel, which is set vertically, and a row of mounting holes 41 are opened on its two opposite side walls.

[0028] The bracket assembly includes a first bracket 1 and a second bracket 2. One end of the first bracket 1 is connected to the front fender body 3, and the other end is connected to the rear suspension 4 near the front fender body 3. One end of the second bracket 2 is connected to the front fender body 3, and the other end is connected to the rear suspension 4 away from the front fender body 3. Both the first bracket 1 and the second bracket 2 are installed on the rear suspension 4 with four M10 bolts and a tightening torque of 46±5 N.m. Bolting avoids excessive weld points and makes fender replacement inconvenient. Furthermore, welding can easily result in weld breaks, affecting the overall lifespan. The connection points between the front fender body 3 and the first bracket 1 and the second bracket 2 are located on opposite sides of the front fender body 3. The first bracket 1 is positioned above the second bracket 2, allowing the second bracket 2 to be wider and have a stronger load-bearing capacity.

[0029] In the existing technology, the bracket assembly for connecting and fixing the mudguard is mainly fixed on the longitudinal beam of the vehicle frame. During the assembly of the mudguard assembly, since the vehicle wiring harness is already fixed inside the longitudinal beam of the vehicle frame, it is not easy to operate the mounting bolts of the mudguard bracket assembly. Employees often perform blind assembly, resulting in low assembly efficiency.

[0030] By adjusting the fixed installation structure of the front fender body 3 to the rear suspension 4, the influence of the frame longitudinal beam wiring harness is avoided, the assembly line convenience is improved, the blind spot of assembly is reduced, the operation convenience of employees is greatly improved, and the assembly efficiency is increased.

[0031] In another embodiment of this application, such as Figure 3 As shown, the rear suspension 4 is provided with a mounting groove 42, and mounting holes 41 are provided on both sides of the mounting groove 42; the first connecting part 11 of the first bracket 1 is connected to the front fender body 3 through the first connecting hole 14, and the second connecting part 13 of the first bracket 1 is bolted to the mounting hole 41 on the groove wall of the rear suspension 4 near the front fender body 3 through its first connecting hole 14; the third connecting part 21 of the second bracket 2 is connected to the front fender body 3 through the second connecting hole 24, and the fourth connecting part 23 of the second bracket 2 is bolted to the mounting hole 41 on the groove wall of the mounting groove 42 away from the front fender body 3 through the second connecting hole 24.

[0032] By setting the first bracket 1 and the second bracket 2, the spatial misalignment between the rear suspension 4 and the front fender body 3 is compensated, and the front fender body 3 is fixed on the rear suspension 4. By setting the first bracket 1 and the second bracket 2 to be connected to the two different groove walls of the mounting groove 42 respectively, the installation difficulty is reduced and the installation convenience is improved. At the same time, the quadrilateral connection structure is formed, which can better ensure the connection strength. The setting of multiple mounting holes 41 makes it easy to adjust the installation position and assembly gap.

[0033] A vehicle includes a bracket assembly and / or a front fender assembly. The application of the aforementioned bracket assembly or front fender assembly in the vehicle results in higher overall installation strength and ensures quality.

[0034] The working process and principle of the above structure are as follows: By using a first bracket 1 and a second bracket 2 to fix the front fender, compared to existing single bent bracket assemblies or pipe beam bracket assemblies, the fixing points of the bracket assembly and the front fender body 3 are distributed, increasing the overall fixing strength of the bracket assembly and improving the overall strength and fixing stability of the fender assembly. Both the first bracket 1 and the second bracket 2 adopt an integrated structural design, effectively avoiding corrosion problems caused by poor welding. The overall strength of the first bracket 1 and the second bracket 2 is guaranteed by the setting of the first flange 15 and the second flange 25. The fixing and installation structure of the front fender body 3 is adjusted to be on the rear suspension 4, avoiding the influence of the frame longitudinal beam wiring harness, improving the convenience of assembly, reducing blind spots in assembly, greatly improving the convenience of operation for employees, and improving assembly efficiency. The distance between the front fender body 3 connected by the second bracket 2 and the rear suspension 4 is greater than the distance between the front fender body 3 connected by the first bracket 1 and the rear suspension 4. To adapt to the installation requirements, the second vertical height difference is set to be greater than the first vertical height difference, forming a quadrilateral fixing structure, which makes the fixing more secure.
