The invention discloses a safe rotating handle with an anti-stall function, and belongs to the field of electric vehicles. According to the scheme, the rotating speed of a rotating shaft is slowed down through the hindering effect of industrial glycerin on a double-layer speed brake, so that in the normal running process of the electric vehicle, damage to a battery caused by rapid acceleration is reduced, and the service life of the battery is prolonged; and secondly, when the rotating speed of the rotating shaft is still high, an elastic speed reducing plate deforms under extrusion of industrial glycerin, a leather bag on the side face of the rigid speed reducing plate is extruded through a protrusion on the side face of the elastic speed reducing plate, a piston is pushed to be communicated with a circuit, a limiting block is pushed out of a sliding groove to be clamped into a limiting groove through magnetism generated by an iron core electromagnet to prevent the rotating shaft from continuing rotating, the potential safety hazard caused by the fact that a rider mistakenly twists the rotating handle due to tension under the emergency condition is reduced, and the safety of the electric vehicle is improved.
本发明公开了一种具有防失速功能的安全转把,属于电动车领域,本方案通过工业甘油对双层减速板的阻碍作用,减缓转轴的转动速度,使得电动车在正常行驶过程中,减少急加速对电池造成的损伤,延长电池的使用寿命,其次,当转轴转动速度依然较快时,弹性减速板在工业甘油的挤压下变形,利用其侧面的凸起挤压刚性减速板侧面的皮囊,推动活塞连通电路,利用铁芯电磁铁产生的磁性将限位块推出滑槽卡入限位槽阻碍转轴继续转动,减少了在紧急情况下骑乘者由于紧张,误拧转把导致安全隐患,提高了电动车的安全性。
