[0035] In order to make the technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the drawings.

[0036] As shown in the figure, the present disclosure provides a vehicle body reinforcing device, which is arranged between the vehicle body side walls and comprises a first plate body 1, a second plate body 2 and a first reinforcing plate 3. One end of the first plate body 1 is connected to one end of the second plate body 2. The first reinforcing plate 3 is located at the end of the first plate body 1 away from the second plate body 2. In the thickness direction of the first plate body 1, the first reinforcing plate 3 at least partially overlaps the first plate body 1. The overlapping region of the first reinforcing plate 3 and the first plate body 1 is located between the vehicle body side walls, thereby improving the strength of the vehicle body reinforcing device. The first reinforcing plate 3 is detachably connected to the first plate body 1, thereby being able to adjust the overlapping area of the first reinforcing plate 3 and the first plate body 1 and the length of the vehicle body reinforcing device, and improve the adaptability of the vehicle body reinforcing device. Figure 1 In some embodiments of the present disclosure, as shown in the figure, the vehicle body reinforcing device further comprises a connecting piece 5. One end of the first plate body 1 is connected to one end of the second plate body 2 through the connecting piece 5. The first plate body 1 and the second plate body 2 are substantially rectangular. The connecting piece 5 is connected to the short side of the first plate body 1 and the short side of the second plate body 2 respectively. The length direction of the first plate body 1 and the length direction of the second plate body 2 form an angle, so that the first plate body 1, the connecting piece 5 and the second plate body 2 form a V-shaped structure.

[0037] Figure 1 ​​​

[0038] Optionally, as shown in Figure 1 One side of the connecting piece 5 is provided with a boss 51 configured to be connected with the cross beam or floor of the vehicle. The boss 51 is located at the included angle position of the V-shaped structure and the middle position of the vehicle body reinforcing device.

Exemplarily, the boss 51 is connected with the cross beam or floor of the vehicle by bolts or welding.

[0039] In some embodiments of the present disclosure, as shown in Figure 1 The vehicle body reinforcing device further comprises a second reinforcing plate 4 at least partially overlapping the second plate body 2 in the thickness direction of the second plate body 2, and the second reinforcing plate 4 is detachably connected with the second plate body 2 away from the first plate body 1, and the end of the second reinforcing plate 4 away from the second plate body 2 is used to be connected with the vehicle body side wall. Specifically, the second reinforcing plate 4 and the first reinforcing plate 3 are substantially rectangular, the second reinforcing plate 4 has the same shape and size as the first reinforcing plate 3, and the second plate body 2 has the same shape and size as the first plate body 1. The second reinforcing plate 4 at least partially overlaps the second plate body 2 in the thickness direction of the second plate body 2 and is detachably connected with the second plate body 2, so that the length of the vehicle body reinforcing device on both sides of the connecting piece 5 can be adjusted. Preferably, the length of the connected second plate body 2 and second reinforcing plate 4 is equal to the length of the connected first reinforcing plate 3 and first plate body 1, that is, the first plate body 1 and the second plate body 2 and the first reinforcing plate 3 and the second reinforcing plate 4 on both sides of the connecting piece 5 form a mutually symmetrical structure, which is beneficial to improve the stress distribution of the vehicle body reinforcing device and avoid stress concentration.

In some embodiments of the present disclosure, as shown in Figure 2 The first plate body 1 is provided with a first reinforcing rib 11 protruding away from the first reinforcing plate 3 in the thickness direction of the first plate body 1. The extension direction of the first reinforcing rib 11 is substantially parallel to the length direction of the first plate body 1. The first reinforcing rib 11 can increase the strength of the first plate body 1 and improve the torsional stiffness of the vehicle body reinforcing device.

[0041] In some embodiments of the present disclosure, as shown in Figure 2As shown, the first reinforcing plate 3 is provided with a second reinforcing rib 31 protruding away from the first plate body 1 in the thickness direction of the first plate body 1. The extending direction of the second reinforcing rib 31 is substantially parallel to the length direction of the first reinforcing plate 3, and the projection of the second reinforcing rib 31 on the first plate body 1 at least partially overlaps the first reinforcing rib 11. The second reinforcing rib 31 can increase the strength of the overlapping part of the first reinforcing plate 3 and the first plate body 1, avoiding the existence of a region with excessively low rigidity between the connecting piece 5 and the vehicle body side wall.

[0042] In some embodiments of the present disclosure, as shown in Figure 2 As shown, the first plate body 1 is provided with a plurality of first connecting holes 12, and the first reinforcing plate 3 is provided with a plurality of first mounting holes 32.

As an example, as shown in Figure 3 As shown, the plurality of first mounting holes 32 are arranged in two groups of 3x3, and the two groups of 3x3 first mounting holes 32 are respectively distributed between the two sides of the second reinforcing rib 31 and the opposite two edges of the first reinforcing plate 3. Figure 4 A schematic view of the first plate body provided in an embodiment of the present disclosure is shown. Correspondingly, as shown in Figure 4 As shown, the plurality of first connecting holes 12 are arranged in two groups of 3x3, and the two groups of 3x3 first connecting holes 12 are respectively distributed between the two sides of the first reinforcing rib 11 and the opposite two edges of the first plate body 1. When connecting the first plate body 1 and the first reinforcing plate 3, the number of overlapping first mounting holes 32 and first connecting holes 12 can be adjusted according to the design needs of the vehicle, for example, four first mounting holes 32 and four first connecting holes 12 are respectively overlapped.

[0044] In some embodiments of the present disclosure, as shown in Figure 3 As shown, the vehicle body reinforcing device further comprises a first bracket 6, the first bracket 6 is connected with the first reinforcing plate 3 through a bolt 61, and the side of the first bracket 6 away from the first reinforcing plate 3 is welded with the vehicle body side wall.

[0045] In some embodiments of the present disclosure, as shown in Figure 4 As shown, the connecting piece 5 is provided with at least two through holes 52 on the side away from the boss 51, and the connecting piece 5 is connected with the first plate body 1 and the second plate body 2 through bolts and the through holes 52 respectively.

[0046] Figure 5 A first plate body 1 and a first reinforcing plate 3 provided in an embodiment of the present disclosure are shown in Figure 2A cross-sectional view at point AA. In some embodiments of this disclosure, such as... Figure 5 As shown, the first reinforcing rib 11 and the second reinforcing rib 31 have arc-shaped cross-sections. An arc-shaped recess is formed on the side of the first plate 1 near the first reinforcing plate 3, and an arc-shaped recess is formed on the side of the first reinforcing plate 3 near the first plate 1. The edges of the arc-shaped recesses formed by the first reinforcing rib 11 and the second reinforcing rib 31 are misaligned. This structure allows the stress on the first plate 1 at the first reinforcing rib 11 and the stress on the first reinforcing plate 3 at the second reinforcing rib 31 to be distributed in different areas, avoiding stress concentration and improving the strength of the vehicle body reinforcement device.

[0047] For example, see Figure 5 The thickness of the first plate 1 is different from the thickness of the first reinforcing plate 3. Preferably, the thickness of the first plate 1 is greater than the thickness of the first reinforcing plate 3.

In some embodiments of this disclosure, such as... Figure 6 As shown, a first reinforcing member 13 is provided at the first reinforcing rib 11 of the first plate 1, extending away from the first reinforcing plate 3 in the thickness direction of the first plate 1. A second reinforcing member 33 is provided at the second reinforcing rib 31 of the first reinforcing plate 3, extending away from the first plate 1 in the thickness direction of the first plate 1. The first reinforcing member 13 and the second reinforcing member 33 can be separate parts and are welded to the first plate 1 and the first reinforcing plate 3 respectively. The first reinforcing member 13 and the second reinforcing member 33 can improve the strength of the first plate 1 and the first reinforcing plate 3, and increase the torsional stiffness of the vehicle body reinforcement device.

[0049] Figure 7 Another first plate 1 and first reinforcing plate 3 provided in the embodiments of this disclosure Figure 2 A cross-sectional view at point AA. In some embodiments of this disclosure, such as... Figure 7 As shown, the first plate 1 bends away from the first reinforcing plate 3 in the region near the first reinforcing rib 11, and the first reinforcing plate 3 bends away from the first plate 1 in the region near the second reinforcing rib 32. This bending structure can increase the gap between the first plate 1 and the first reinforcing plate 3 in the overlapping area and increase the superposition thickness of the first plate 1 and the first reinforcing plate 3, which is beneficial to improving the torsional stiffness of the vehicle body reinforcement device.

[0050] It should be noted that the cross-sectional structure of the second plate 2 and the second reinforcing plate 4 can be the same as that of the first plate 1 and the first reinforcing plate 3, respectively.

[0052] In some embodiments of the present disclosure, referring to Figure 1 , the second reinforcing plate 4 is provided with a fourth reinforcing rib 41 protruding away from one side of the second plate body 2 in the thickness direction of the second plate body 2. The extending direction of the fourth reinforcing rib 41 is substantially parallel to the length direction of the second reinforcing plate 4, and the projection of the fourth reinforcing rib 41 on the second plate body 2 at least partially overlaps with the third reinforcing rib 21. The fourth reinforcing rib 41 can increase the strength of the overlapping part of the second reinforcing plate 4 and the second plate body 2, and avoid the existence of a region with excessively low stiffness between the connecting member 5 and the vehicle body side wall.
