In other embodiments, other driving schemes may be used. For example, the drive shaft of the drive element is in driving connection with the outer bearing ring or the inner bearing ring via a belt. I.e. the tendency of the rotary motion of the drive shaft is transmitted to the first rotating member 51 or the second rotating member 52 by means of a conveyor belt so as to cause a relative rotary motion thereof. This arrangement provides a wider range of space for the drive member to fit in. In other embodiments, it is even possible to provide the driving member with a driving screw, and the outer ring of the first rotating member 51 or the second rotating member 52 is provided with a docking gear, and the driving screw of the driving member is meshed with the docking gear of the first rotating member 51 or the second rotating member 52. The stability is better through the transmission of butt joint gear.

In addition, when the rotating assembly 5 is provided, the second rotating member 52 further includes a support plate 521, and the seat body 1 is connected to the support plate 521 to form a stable support plane, so as to further ensure the stability of the child safety seat during use.
