[0033] Figure 2 The figure shows the axle side structure diagram of the sub-frame structure provided by the embodiment of the present application. Figure 3 Shown Figure 2 Schematic diagram of the exploded structure of the subframe structure. Figure 2 and Figure 3 As shown, the subframe structure provided by the embodiment of the present invention includes a longitudinal beam 11, a rear mounting bracket 12, a rear cross beam 21, a rear cross beam lower plate 22 and a reinforcement bracket 30. The longitudinal beam 11 and the rear mounting bracket 12 are fixed to each other to form a first structure 10, and the rear cross beam 21 and the rear cross beam lower plate 22 are fixed to each other to form a second structure 20. The first structure 10 and the second structure 20 are fixedly connected. At the end of the rear cross beam 21 facing the first structure 10, the outer side surface of the rear cross beam 21 (i.e. Figure 5 The middle rear cross member 21 is located on the side above the paper) toward the middle of the sub-frame structure (i.e. Figure 5 The bottom of the middle paper is recessed to form a relief portion 23. The reinforcing bracket 30 is detachably covered on the relief portion 23.

[0034] By forming a relief portion 23 on the rear cross member 21 and installing a removable reinforcement bracket 30 on the relief portion 23, when repairing the cooling system, the reinforcement bracket 30 can be removed first, and then the cooling system can be repaired through the relief portion 23, without having to dismantle the subframe structure. In other words, in this embodiment, the provision of the relief portion 23 provides space for repairing the cooling system, while the reinforcement bracket 30 ensures the strength of the rear cross member 21 where the relief portion 23 is installed. Therefore, this subframe structure facilitates cooling system repairs, reducing labor and time costs.

[0035] In this embodiment, the longitudinal beam 11 may be the right longitudinal beam, and the rear mounting bracket 12 may be the right rear mounting bracket. It is understood that in other embodiments, the longitudinal beam 11 may be the left longitudinal beam, and the rear mounting bracket 12 may be the left rear mounting bracket. In other words, the longitudinal beam 11 and the rear mounting bracket 12 may be on the same side of the vehicle.

[0036] Figure 4 Shown Figure 2 The structural diagram of the middle reinforcement bracket. Please continue to refer to Figures 1 to 4 In this embodiment, the longitudinal beam 11 and the rear mounting bracket 12 can be welded together, and the rear cross beam 21 and the rear cross beam lower plate 22 can also be welded together. The reinforcement bracket 30 can be removably connected to the first structure 10 and the second structure 20 via fasteners 41, such as bolts. To ensure the strength of the subframe structure, the connection holes 42 for the fasteners 41 are located at the junction of the longitudinal beam 11 and the rear mounting bracket 12 on the first structure 10; and the connection holes 42 for the fasteners 41 are located at the junction of the rear cross beam 21 and the rear cross beam lower plate 22 on the second structure 20.

[0037] Furthermore, in this embodiment, the reinforcing bracket 30 includes an upper plate 31, a connecting plate 32 and a lower plate 33, wherein the connecting plate 32 is connected between the upper plate 31 and the lower plate 33. When the reinforcing bracket 30 is mounted on the sub-frame structure, the upper plate 31 and the lower plate 33 are sandwiched between the upper and lower sides of the avoidance portion 23. Figure 4 As shown, the reinforcement bracket 30 can be configured in a U-shape. The fastener 41 passes through the lower plate 33 and the upper plate 31 to cover the reinforcement bracket 30 on the avoidance portion 23.

[0038] To ensure mounting strength, a nut 43 is welded to the upper surface of the upper plate 31. During installation, the fastener 41 extends from the lower surface of the lower plate 33 and engages with the nut 43 on the upper plate 31. By welding the nut 43 directly to the upper surface of the upper plate 31, the mounting of the bracket 30 is strengthened.

Figure 6 The figure shows the cross-sectional structure diagram of the longitudinal beam and the rear mounting bracket at the sleeve. Figure 7 The figure shows the cross-sectional structure of the rear cross beam and the lower plate of the rear cross beam at the sleeve. Figure 8 Shown Figure 3 The structural diagram of the middle reinforcement plate. Please continue to refer to Figure 3 、 Figures 5 to 8 In this embodiment, in order to ensure the stability of the connection, a knurled structure can also be provided on the end faces at both ends of the connecting hole 42 to prevent the reinforcing bracket 30 from slipping relative to the connecting hole 42.

[0040] A sleeve 44 may be provided in the connection hole 42. The fastener 41 is connected to the upper plate 31 by passing through the sleeve 44 after passing through the lower plate 33. The provision of the sleeve 44 can greatly improve the strength of the connection between the fastener 41 and the first structure 10 and the second structure 20.

[0041] For further information, please refer to Figure 3 、 Figure 5 and Figure 8 In this embodiment, the rear crossbeam 21 may include a rear crossbeam body 211 and a reinforcement plate 212. The rear crossbeam body 211 is fixedly connected to the rear crossbeam lower plate 22, and the reinforcement plate 212 is fixedly connected to the rear crossbeam body 211. The rear crossbeam body 211 is connected to the first structure 10 via the reinforcement plate 212, and the aforementioned avoidance portion 23 is formed on the reinforcement plate 212.

[0042] By providing the reinforcement plate 212 , on the one hand, the strength of the avoidance area can be adjusted, and on the other hand, the structure of the reinforcement plate 212 can be fine-tuned for different vehicle models, so that the same subframe structure can be adapted to more different vehicle models or designs.

[0043] Furthermore, a flange 2121 is formed around the reinforcing plate 212 , and the reinforcing plate 212 is welded to the rear cross beam body 211 and the first structure 10 via the flange 2121 , so as to further improve the strength of the area where the avoidance portion 23 is located.

[0044] In summary, in the present invention, the provision of the relief portion 23 provides operating space for cooling system maintenance, while the provision of the reinforcing bracket 30 ensures the strength of the rear cross member 21, on which the relief portion 23 is provided. Therefore, this subframe structure facilitates cooling system maintenance, reducing labor and time costs.
