The invention discloses a safety seat rotating and pitching driving control method and a safety seat thereof. According to the method, a first motor drives a lead screw and a nut to achieve linear displacement so as to drive a seat body to conduct pitching adjustment, and a second motor drives the seat body to conduct rotating adjustment through gear meshing between a driving disc and a rotating disc. Besides, the working currents of the two motors are collected and calculated to obtain the current change rate, when the current change rate exceeds the preset value, the two motors are controlled to stop urgently to avoid injury to the child, the safety of the safety seat is improved on the basis that the safety seat is easy to implement in the industry, and the stability of the safety seat is good.
本发明公开了一种安全座椅旋转和俯仰驱动控制方法及其安全座椅,该方法通过第一电机带动丝杆和螺母实现直线位移以带动座椅主体进行俯仰调节,通过第二电机经驱动盘与转盘之间的齿轮啮合驱使座椅主体进行转动调节。此外,还通过采集两电机的工作电流并运算得到电流变化率,并在超过预设值时控制两电机急止而避免儿童伤害,实现了在工业上易实现的基础上提升安全座椅的安全性,且该安全座椅的稳定性良好。
