[0037] Please refer to Figures 1 to 8, a description is now provided for the front suspension mounting structure provided by the present utility model. The front suspension mounting structure includes a front suspension support reinforcement plate 4, an inner front panel reinforcement plate 3, a front suspension support mounting bracket 6, and a front suspension support bushing 2. The front suspension support reinforcement plate 4 is fixed to the front suspension mounting area on the inner side of the outer front panel 5 to enhance the stiffness of the outer front panel 5. The inner front panel reinforcement plate 3 is fixed to the front suspension mounting area on the outer side of the inner front panel 1 to enhance the stiffness of the inner front panel 1. The front suspension support mounting bracket 6 is fixed to the inner side of the front suspension support reinforcement plate 4. An installation hole 63 is provided on the front suspension support mounting bracket 6, and the front suspension support mounting bracket 6 has a fixing and guiding effect on the front suspension support bushing 2. The front suspension support bushing 2 passes through the installation hole 63 and is fixedly connected to the front suspension support mounting bracket 6, and its two ends are respectively fixed to the front suspension support reinforcement plate 4 and the inner front panel reinforcement plate 3. A connecting bolt passes through the front suspension support bushing 2, and the front suspension support bushing 2 supports the front suspension rotating body, reduces the friction coefficient during its movement, and ensures its rotation accuracy. First through holes for the connecting bolt to pass through are correspondingly provided on the outer front panel 5 and the inner front panel 1, and second through holes 43 for the connecting bolt to pass through are provided on the front suspension support reinforcement plate 4 and the inner front panel reinforcement plate 3 accordingly.

[0038] Among them, the front suspension support reinforcement plate 4 and the inner front panel reinforcement plate 3 are joined to form a first box-shaped structure, as shown in Figures 1 to 4 shown.

[0039] Compared with the prior art, the beneficial effects of the front suspension mounting structure provided by the present utility model are as follows: (1) The front suspension support reinforcement plate 4 is fixed to the front suspension mounting area on the inner side of the outer front panel 5, and the inner front panel reinforcement plate 3 is fixed to the front suspension mounting area on the outer side of the inner front panel 1. The front suspension support mounting bracket 6 is fixed to the front suspension support reinforcement plate 4, and the front suspension support bushing 2 is fixed between the front suspension support reinforcement plate 4 and the inner front panel reinforcement plate 3. The front suspension support reinforcement plate 4 and the inner front panel reinforcement plate 3 enhance the stiffness of the front suspension mounting area on the front end assembly, and also provide strength support for both ends of the front suspension support bushing 2, thereby facilitating the improvement of the stiffness of the front suspension mounting point, reducing the risk of damage to the connecting bolt, further facilitating the improvement of the service life of the connecting bolt, avoiding the safety risk of the front suspension falling off due to the fracture of the connecting bolt, and also being able to avoid the generation of abnormal noises.

[0040] (2) The connecting bolt of the front suspension penetrates into the front suspension support bushing, enabling the front suspension to rotate more smoothly, reducing the wear of the connecting bolt, further extending the service life, and reducing potential safety hazards.

[0041] (3) The front suspension support reinforcement plate 4 is connected to the front inner panel reinforcement plate 3 to form a box structure. With the clamping of the front suspension support reinforcement plate 4 and the front inner panel reinforcement plate 3, the stiffness of the front suspension installation area is greatly improved. Protected by the bushing, it can not only ensure the smooth rotation of the connecting bolt, but also avoid the safety risk of the front suspension falling off due to the wear and fracture of the connecting bolt. Moreover, it can also avoid abnormal noise and wear caused by collision, reduce the replacement frequency, lower the use cost, and greatly extend the service life of the connecting bolt and the front suspension.

[0042] (4) The protection of the front suspension support bushing 2 and the improvement of the stiffness of the front-end assembly not only eliminate the damage to the connecting bolt during long-term use and extend the service life of the connecting bolt, but also make the cab more smooth during the flipping process, improving the user experience.

[0043] It should be noted that the front suspension mounting points of existing heavy trucks are set on the front-end assembly. Although a single-layer reinforcement plate is set on the front-end assembly to enhance the stiffness, due to the flipping of the front suspension mounting position during the vehicle's driving, the low stiffness is insufficient to support the flipping of the front suspension. In order to improve the stiffness of the front-end assembly, the single-layer reinforcement plate generally uses high-strength steel plates or increases the material thickness for design. This design makes the strength of the reinforcement plate higher than that of the connecting bolt connecting the front suspension. Therefore, during the collision process, the connecting bolt will be worn, and this design also causes an increase in materials, resulting in an increase in labor costs and die costs. In this application, an installation structure of the front suspension support reinforcement plate 4, the front inner panel reinforcement plate 3, the front suspension support mounting bracket 6, and the front suspension support bushing 2 is set in the front suspension installation area. By protecting the connecting bolt and strengthening the installation points at both ends of the connecting bolt, the purpose of avoiding the wear of the connecting bolt can be achieved, thereby reducing the damage phenomenon of the connecting bolt, facilitating the extension of the service life of the connecting bolt, and further extending the service life of the front suspension.

[0044] In some embodiments, as shown in Figures 3 to 4 The front suspension support reinforcement plate 4 is laminated and welded to the inner side of the front outer panel 5 to form a first-level structure; the front inner panel reinforcement plate 3 is laminated and welded to the outer side of the front inner panel 1 to form a second-level structure. The front suspension support reinforcement plate 4 and the front inner panel reinforcement plate 3 form a double-level installation structure through the front suspension support bushing 2 and the front suspension support mounting bracket 6. And the front outer panel 5 and the front inner panel 1 are welded to form a welding box structure with very high stiffness, further improving the stiffness of the front suspension installation area, thereby reducing the wear of the front suspension connecting bolt and greatly extending its service life.

[0045] Specifically, the front suspension support reinforcement plate 4, the front suspension support mounting bracket 6, and the front suspension support bushing 2 are welded to form the front suspension support mounting plate assembly. The front suspension support mounting plate assembly and the front outer panel 5 form the welding assembly level of the front outer panel 5. The front inner panel reinforcement plate 3 and the front inner panel 1 form the welding assembly of the front inner panel 1. Finally, the welding assembly of the front inner panel 1 and the welding assembly of the front outer panel 5 are welded into an integral front panel assembly, making the structure into a box-shaped structure with stable stiffness.

[0046] In some embodiments, after the front outer panel 5 and the front inner panel 1 are welded together in the front suspension installation area, a second box-shaped structure is formed (see Figure 3 ), and the second box-shaped structure is located outside the first box-shaped structure, so that the front suspension installation area forms a double-box body reinforcement structure with a box-in-box shape, which has the effect of energy absorption and shock absorption, and can also improve the user experience.

[0047] Specifically, two front suspension support mounting brackets 6 are welded on the front suspension support reinforcement plate 4, which can fix two front suspension support bushings 2 and pass through two connecting bolts. The front suspension support mounting bracket 6 is welded to the front suspension support bushing 2 by CO2 shielded arc welding and to the front suspension support reinforcement plate 4 by spot welding.

[0048] In some embodiments, see Figures 4 to 9 As shown, the upper edge and the lower edge of the front suspension support reinforcement plate 4 are respectively provided with first reinforcing flanges 41 bent inward; four overlapping parts 61 are dispersedly arranged around the front suspension support mounting bracket 6, and among them, two overlapping parts 61 opposite to each other up and down are fixed on the first reinforcing flange 41. The setting of the first reinforcing flange 41 can improve the stiffness of the front suspension support reinforcement plate 4, thereby improving the support strength of the front suspension installation area; one of the first reinforcing flanges 41 is attached to the front outer panel 5, improving the fixing firmness of the front suspension support reinforcement plate 4 and the front outer panel 5. The front suspension support mounting bracket 6 is fixed to the front suspension support reinforcement plate 4 through the overlapping part 61, which can not only make the two form a box-shaped structure, but also ensure the fixing firmness of the front suspension support mounting bracket 6.

[0049] In some embodiments, see Figure 8 and Figure 9 As shown, two overlapping parts 61 opposite to each other up and down have overlapping edges 62 bent in the opposite direction, and the overlapping edges 62 are stacked and welded on the first reinforcing flange 41. By making the overlapping edges 62 and the first reinforcing flange 41 in contact with each other, the contact area between the two is increased, and the fixing firmness of the front suspension support mounting bracket 6 can also be improved.

[0050] In some embodiments, see Figure 5As shown, the middle part of the front suspension support reinforcing plate 4 also has a reinforcing rib 42 extending in the up and down directions. By providing the reinforcing rib 42, the stiffness of the front suspension support reinforcing plate 4 is further improved, thereby being able to improve the stiffness of the front suspension installation area, reduce the phenomenon of damage to the connecting bolts, facilitate the extension of the service life of the connecting bolts, and further improve the service life of the front suspension.

[0051] Among them, the reinforcing rib 42 is located at the middle position between the two front suspension support bushings 2.

[0052] In some embodiments, as shown in Figure 5 As shown, the reinforcing rib 42 is formed by the middle part of the front suspension support reinforcing plate 4 protruding inward. The side of the reinforcing rib 42 facing the front panel outer plate 5 forms a groove, thus forming a third box-shaped structure, which further improves the stiffness of the front suspension installation area, reduces the phenomenon of damage to the connecting bolts, facilitates the extension of the service life of the connecting bolts, and further improves the service life of the front suspension.

[0053] As shown in Figures 4 to 8 As shown, in some embodiments, the upper edge and the lower edge of the front panel inner plate reinforcing plate 3 are respectively provided with second reinforcing flanges 31 bent outward; at least one second reinforcing flange 31 overlaps with the first reinforcing flange 41 on the same side to form the first box-shaped structure. The second reinforcing flanges 31 on the front panel inner plate reinforcing plate 3 can also improve the structural strength of the front panel inner plate reinforcing plate 3 itself, and further improve the support strength of the front suspension installation area, which is beneficial to the extension of the service life of the connecting bolts.

[0054] In some embodiments, as shown in Figure 4 As shown, the front panel inner plate reinforcing plate 3 is provided with a weight-reducing hole 32. While improving the stiffness in this application, the weight increase and cost rise are avoided by providing the weight-reducing hole 32, which is beneficial to the lightweight of the components and the reduction of the manufacturing cost.

[0055] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not detailed or recorded in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0056] Based on the same inventive concept, the embodiments of the present application also provide a vehicle, including the front suspension installation structure described above.

[0057] In the vehicle provided by the embodiment of the present utility model, the outer front panel 5 and the inner front panel 1 are welded around the front suspension mounting area to form a box-shaped structure, and are clamped by the front suspension support reinforcing plate 4 and the inner front panel reinforcing plate 3, greatly improving the stiffness of the front suspension mounting area. With the protection of the bushing, it can not only ensure the smooth rotation of the connecting bolt, but also avoid the safety risk of the front suspension falling off due to the wear and fracture of the connecting bolt. Moreover, it can also avoid abnormal noise and wear caused by collision, greatly improving the service life of the connecting bolt and the front suspension.

[0058] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
