In the specific embodiment shown in fig. 4, at least a portion of the main plate body 1211 is recessed toward a side of the main plate body 1211 to form a receiving groove 123, and the receiving groove 123 is an arc-shaped groove surrounding at least a portion of the first fastening member 122 at an outer side of the first fastening member 122. That is, the receiving groove 123 is formed in the main plate 1211, and the receiving groove 123 is an arc-shaped groove recessed toward one side of the main plate 1211. In this way, the first fastening member 122 can fit in the receiving groove 123, so that the connection of the first fastening member 122 on the reinforcing base 121 is more secure and reliable.

As shown in fig. 4 and 6, the accommodating groove 123 is defined by the transition limiting arc surface 1231 and the connection arc surface 1232, the lower end of the connection arc surface 1232 is flush with the lower edge of the main board 1211, the upper end of the connection arc surface 1232 is connected with the transition limiting arc surface 1231, the transition limiting arc surface 1231 gradually extends outwards from the end connected with the connection arc surface 1232 to form an arc surface of an indent with a gradually reduced diameter, the connection arc surface 1232 is adapted to the first fastening member 122, and the transition limiting arc surface 1231 is limited to the first fastening member 122 above the connection arc surface 1232.

Therefore, the connecting cambered surface 1232 is adapted to the first fastening member 122, the first fastening member 122 is installed in the connecting cambered surface 1232, the lower end surface of the first fastening member 122 can be flush with the lower edge of the main plate 1211, so that the first fastening member 122 is opposite to the installation through hole 1111, the adjustment of the relative position between the component to be fixed on the longitudinal beam 110 and the first fastening member 122 is simpler and more convenient, the interference of the lower edge of the main plate 1211 on the first fastening member 122 can be avoided, and by arranging the transition limiting cambered surface 1231, the first fastening member 122 is limited above the connecting cambered surface 1232, and meanwhile, the accommodating groove 123 and the main plate 1211 can be smoothly transited, so that the processing difficulty of the reinforcing base 121 is reduced, and the stress concentration of the main plate 1211 is avoided.

In the specific embodiment shown in fig. 6, a first transition fillet 124 is arranged between one end of the accommodating groove 123 and the main plate 1211, a second transition fillet 125 is arranged between the main plate 1211 and the connecting flange 1212, a third transition fillet 126 is arranged between the other end of the accommodating groove 123 and the connecting flange 1212, the radius of the first transition fillet 124 is R1, the radius of the second transition fillet 125 is R2, and the radius of the third transition fillet 126 is R3, wherein R3 is greater than or equal to R2 and greater than R1.
