The embodiment of the invention discloses an electric vehicle rotating handle device. The device comprises a rotating assembly, a fixing assembly and a motor controller. A magnet is arranged on the rotating assembly; the fixing assembly is provided with a first Hall element and a second Hall element. The rotating assembly is nested in the fixing assembly and rotates relative to the fixing assemblyso that the magnet moves relative to the first Hall element and the second Hall element, the first Hall element induces a magnetic field signal of the magnet to generate a first voltage signal, and the second Hall element induces a magnetic field signal of the magnet to generate a second voltage signal; and the motor controller is used for adjusting the rotating speed of the motor according to the first voltage signal or the second voltage signal when detecting that the first voltage signal and the second voltage signal meet a preset voltage rule. According to the embodiment of the invention,the double Hall elements are adopted to realize speed regulation, and whether the rotating handle demand signal is reliable or not is judged according to the two Hall voltage parameter values so thathigher interference resistance, stability and safety are achieved.
本发明实施例公开了一种电动车转把装置,该装置包括:转动组件、固定组件和电机控制器;转动组件上设置有一磁铁;固定组件上设置有第一霍尔元件和第二霍尔元件,转动组件嵌套在固定组件内且相对于固定组件转动,使磁铁相对于第一霍尔元件和第二霍尔元件移动,第一霍尔元件感应磁铁的磁场信号以产生第一电压信号,第二霍尔元件感应磁铁的磁场信号以产生第二电压信号;电机控制器用于检测到第一电压信号和第二电压信号满足预设电压规则时,根据第一电压信号或第二电压信号调节电机转速。本发明实施例,采用双霍尔元件实现调速,根据两个霍尔电压参数值判断转把需求信号是否可靠,具有更强的抗干扰性、稳定性和安全性。
