The invention relates to a child seat with a rotating mechanism. The child seat comprises a base, a seat body and the rotating mechanism enabling the seat body to be rotatably installed on the base. The base comprises a base shell and a base framework used for increasing the strength of the base shell. The base framework is mounted in the base shell; the rotating mechanism comprises a rotating disc and a plurality of rollers; the plurality of rollers are annularly arranged around the rotating axis of the rotating disc; the radius of the rotating disc is larger than or equal to 110 mm and smaller than or equal to 150 mm. The difference between the radius of the rotating disc and the radius of the annularly arranged rollers is less than or equal to 15mm; a horizontal reference surface is defined at the bottom of the base shell; the included angle between the rotating axis of the rotating disc and the horizontal datum plane is larger than or equal to 76 degrees and smaller than or equal to 80 degrees. The anti-impact device has the beneficial effects that the anti-impact performance is effectively improved through the arrangement of the rotating disc, particularly, the forward impact resistance can be effectively improved, and the possibility of forward inclination is reduced when the anti-impact device is subjected to reverse impact force.

    本发明涉及一种带有旋转机构的儿童座椅,包括:底座、椅身和使椅身可转动地安装至底座的旋转机构;底座包括:底座壳体和用于增加底座壳体的强度的底座骨架;底座骨架安装至底座壳体内;旋转机构包括:旋转盘和多个滚轮;多个滚轮环绕旋转盘的转动轴线成环形排布;旋转盘的半径大于等于110mm且小于等于150mm;旋转盘的半径与多个滚轮的环形排布的半径之差小于等于15mm;底座壳体的底部定义一个水平基准面;旋转盘的转动轴线与水平基准面的夹角大于等于76度且小于等于80度。本发明的有益之处在于,通过对旋转盘的设置有效提升抗冲击性能,尤其是可以有效提升抗正向冲击的性能,并在受到反向冲击力时将降低前倾的可能性。
