Other technical solutions of this embodiment are as described in the first embodiment, and this embodiment will not be described repeatedly.

Example three:

the number of the pressing plates arranged on the annular hoop body 1 of the intelligent hula hoop is three, meanwhile, the number of the folding supports is also three, the number of the folding supports is three, the arc-shaped sliding rods 6 are connected with the first ends of the second supporting rods 402 of the three folding supports, and therefore when the driving pieces drive the arc-shaped sliding rods 6 to move, the three folding supports can be adjusted to be unfolded or folded at the same time. In other embodiments, the number of the pressing plates and the folding brackets can be four, five or more, and the like.

Example four:

referring to fig. 3 and 6, an opening 106 extending along the length direction of the annular hoop body 1 is formed in the inner side wall of the annular hoop body 1 of the intelligent hula hoop, both the first end of the first strut 401 and the first end of the second strut 402 are in clearance fit in the opening 106, and an annular wall 107 which is arranged along the circumferential direction of the opening 106 and protrudes radially outward is formed in the inner side wall of the annular hoop body 1 at the outer edge of the opening 106. The arrangement of the annular wall 107 at the outer edge of the opening 106 on the inner side wall of the annular ring body 1 protects the connection part of the first support rod 401 and the second support rod 402 with the annular ring body 1, and can prevent the annular ring body 1 from being damaged or the first support rod 401 and the second support rod 402 from being broken when the first support rod 401 and the second support rod 402 rotate.
