The mounting nut 2 has a certain moving space in the accommodating space 3, and when the vehicle body mounting bracket and the front auxiliary frame are mounted, the mounting nut 2 can automatically adjust the position to adapt to the front auxiliary frame, so that the mounting stress caused by the size deviation in the mounting process of the front auxiliary frame is eliminated. The movable range of the mounting nut 2 is set according to the range of dimensional deviation of the front subframe.
A circumferential limiting surface 31 is arranged in the accommodating space 3, so that the mounting nut 2 has a certain rotatable angle; meanwhile, in the process of mounting the vehicle body mounting bracket and the front auxiliary frame, when the bolt is inserted into the threaded hole 21 of the mounting nut 2 for locking, the mounting nut 2 is abutted against the circumferential limiting surface 31 to limit the circumferential rotation of the mounting nut 2, and the locking of the mounting nut 2 is not influenced.
As shown in fig. 4, a chamfer 22 is formed at the boundary between the threaded hole 21 of the mounting nut 2 and the end surface of the mounting nut 2 facing the mounting hole 11. The chamfer 22 serves as a guide for the bolt to be inserted smoothly into the threaded hole 21 of the mounting nut 2 during the mounting of the vehicle body mounting bracket to the front subframe.

According to the structure of the mounting nut 2, the limiting structure of the accommodating space 3 is arranged, so that the accommodating space 3 can roughly position the mounting nut 2, and meanwhile, the mounting nut 2 can be ensured to have a certain moving space.
Specifically, the inner surface of the accommodating space 3 forms a first stopper surface 32 and a second stopper surface 33 which are disposed opposite to each other, and the first stopper surface 32 and the second stopper surface 33 are disposed at both ends of the flange 24 in the axial direction of the mounting nut 2.

In addition, as shown in fig. 5, the shortest distance L from the circumferential direction restricting surface 31 to the axis of the center post 23 in the radial direction of the center post 23 is smaller than the longest distance L from the cross section of the outer circumferential surface of the flange 24 perpendicular to the axial direction of the center post 23 to the axis of the center post 231(ii) a The shortest distance L from the circumferential limiting surface 31 to the axis of the central column 23 along the radial direction of the central column 23 is greater than the shortest distance L from the cross section of the outer circumferential surface of the flange 24 perpendicular to the axial direction of the central column 23 to the axis of the central column 232. Through the arrangement, the mounting nut 2 can have a certain rotatable angle; meanwhile, when the bolt is inserted into the threaded hole 21 of the mounting nut 2 for locking, the flange 24 abuts against the circumferential direction stopper surface 31 to restrict circumferential rotation of the mounting nut 2.
As shown in fig. 1 to 4, the bracket body 1 includes a fixing plate 12 and a reinforcing plate 13, the fixing plate 12 and the reinforcing plate 13 are fixed to each other, the accommodating space 3 is formed between the fixing plate 12 and the reinforcing plate 13, and the mounting hole 11 is located on the fixing plate 12.
