The reinforcement 1 can be provided to increase the local stiffness around the bolt.

[0037] like Figure 2 As shown, in this example, the bent portion 102 of the reinforcement 1 is suitable for connecting with the first connecting portion 2. The bent portion 102 is designed to be bent, so as to increase the connection length and area, thereby improving the connection stability of the reinforcement 1. The reinforcement 1 is connected to the lower side of the rear floor 7 and can also support the rear floor 7.

[0038] like Figure 1 As shown, in this example, the bending portion 102 is connected to the first connection portion 2 at one end thereof, and the second connection portion 101 is located at the end of the reinforcement 1 facing the rear floor 7. The bending portion 102 and the second connection portion 101 are arranged adjacent to each other to make the connection structure of the reinforcement 1 more compact.

[0039] The bending portion 102 may be U-shaped, V-shaped or concave, etc., which may be determined by those skilled in the art according to actual conditions and is not specifically limited here. The reinforcement member 1 may be a metal plate, and the bending portion 102 may be formed by stamping, bending, rolling and other processes of the metal plate to ensure the forming accuracy of the bending portion 102 and avoid strength reduction or stress concentration caused by processing defects.

[0040] In this example, the rear floor 7 is fixedly connected to the first connection portion 2. The connection method can be selected by welding, bolting, bonding or other appropriate mechanical connection methods according to design requirements.

The bent portion 102 is arranged along the through hole 92 to ensure that the through hole 92 has sufficient strength to withstand the pulling force and shearing force during the towing operation.

[0053] The bending portion 102 is arranged along the circumference of the through hole 92. The shape, size, angle and other parameters of the bending portion 102 should be optimized according to the stress analysis results to ensure that it can effectively disperse the stress transmitted from the inner wall of the through hole 92 to the first connecting portion 2 and improve the structural stability.
