[0028] Example

[0029] Please refer to Figure 1 The present embodiment provides a rolled profile structure applied to a power battery tray, including a rolled profile body 1 with a hollow interior, an opening 2 being provided at the top of the rolled profile body 1, the rolled profile body 1 being located on one side of the opening 2 as a first bending end, and the rolled profile body 1 being located on the other side of the opening 2 as a second bending end; a first oblique support 3 is provided inside the rolled profile body 1, the top of the first oblique support 3 is connected to the second bending end, and the bottom of the first oblique support 3 is connected to the bottom inner side wall of the rolled profile body 1; a first connecting plate 4 is provided at the first bending end, and the first connecting plate 4 is connected to the first oblique support 3.

[0030] Preferably, a second connecting plate 6 and an arcuate second bent plate 7 are provided between the bottom of the first oblique support 3 of the present embodiment and the rolled profile body 1, one end of the second bent plate 7 is connected to the bottom of the first oblique support 3, and the other end of the second bent plate 7 is connected to the second connecting plate 6; the second connecting plate 6 is connected to the bottom inner wall of the rolled profile body 1. An arcuate first bent plate 5 is provided between the first bent end and the first connecting plate 4 of the present embodiment, one end of the first bent plate 5 is connected to the first bent end, and the other end of the first bent plate 5 is connected to the first connecting plate 4. An arcuate third bent plate 8 is provided between the top of the first oblique support 3 of the present embodiment and the second bent end, one end of the third bent plate 8 is connected to the second bent end, and the other end of the third bent plate 8 is connected to the top of the first oblique support 3.

[0031] The rolled profile structure applied to the power battery tray provided in the present application is different from the common Japanese-shaped profile section. The angled structure formed by the first inclined support 3 is used to replace the middle Japanese-shaped structure, thereby improving the overall rigidity. It also improves the stress distribution of the profile: the angled structure can distribute stress more evenly and reduce the risk of stress concentration, which can improve the strength and stability of the structure in certain box structures. Improve structural rigidity: When subjected to bending moment or torque, the angled structure can resist deformation better than a right angle. Improve assembly conditions: The angled structure is easier to assemble and connect other components, and it can provide a larger contact area, thereby increasing the stability of the connection.

[0032] Alternatively, if Figure 2 As shown, the first bending plate 5 of this embodiment may also adopt a flat plate structure. Figure 5 As shown, the position of the bending point (i.e., the position of the opening 2) is determined according to the actual connection strength required by the profile, and is generally located at one-third to two-thirds of the profile. Because the bevel can reserve a larger profile cavity space on one side, the position of the bending point can also be determined according to the inner cavity requirements.

[0033] Extension length α (the length of each connecting plate): The extension length is generally 3-6 mm. The actual extension length is determined by the total length of the profile and the degree of stress concentration on the load-bearing surface.

[0034] Angle β: The bevel angle is limited by processing conditions and is generally between 55°-70°.

[0035] Thickness T: The thickness of the profile is determined by the load requirements and structural strength requirements. Since the angled structure itself can disperse the force in the width direction, the thickness can be reduced according to the force requirements. Reducing the thickness is conducive to reducing weight and reducing costs.

[0036] Bending arc angle R: For profile bending, applying a certain arc angle can help reduce the stress concentration of the material, making the bend more solid and stable. It can also reduce the sharpness of the profile edge and reduce the risk of damage to the product appearance.

[0037] like Figure 3 As shown, in some embodiments of the present invention, a U-shaped groove 9 is provided on the top of the roll-formed profile body 1, and the number of the grooves 9 is two and they are respectively located on both sides of the opening 2. The present invention can further enhance the structural strength of a single side by providing the U-shaped groove 9 and performing a U-shaped concave bend on the strength surface of the profile.

[0038] like Figure 4 As shown, in some embodiments of the present invention, a second oblique support 10 is provided in the rolled profile body 1, and the second oblique support 10 forms a V shape with the first oblique support 3; a fourth curved plate 11 is provided at the top of the second oblique support 10, and a fourth connecting plate 12 is provided on the fourth curved plate 11, and the fourth connecting plate 12 is connected to the top inner side wall of the rolled profile body 1; a fifth curved plate 13 is provided at the bottom of the second oblique support 10, and the fifth curved plate 13 is connected to the second connecting plate 6. The present invention further enhances the structural strength by providing the second oblique support 10, thereby creating a stronger load section.

It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application.
