The invention provides a single-wheel steering mechanism. The single-wheel steering mechanism comprises a driving part; the directional wheel assembly is arranged below the driving part; the steering shaft is vertically arranged on one side of the driving part; the top end of the steering shaft is in driving connection with the driving part; the bottom end of the steering shaft is in driving connection with the directional wheel assembly; the control part is electrically connected with the driving part; the limiting module comprises a cam arranged on the steering shaft in a sleeving mode and a limiting piece arranged on the outer side of the cam. The cam is connected with the steering shaft; the limiting piece is electrically connected with the driving part, and when the rotation angle of the steering shaft exceeds a threshold value, the cam extrudes the limiting piece, so that the limiting piece is triggered. The cam is connected with the steering shaft so that the cam can rotate along with the steering shaft. When the rotating angle of the steering shaft exceeds a threshold value, the cam extrudes the limiting piece, and therefore the limiting piece is triggered. Also provided is a method. The limiting piece is electrically connected with the driving part, after the limiting piece is triggered, the control part changes output of the driving part, the steering shaft can rotate backwards, and the situation that the steering angle is too large can be avoided.

    本发明提供了一种单轮转向机构,包括:驱动部;定向轮组件,设置在驱动部的下方;转向轴,竖立设置在驱动部的一侧;转向轴的顶端与驱动部驱动连接,转向轴的底端用于与定向轮组件驱动连接;控制部,与驱动部电连接;限位模块,包括套设在转向轴上的凸轮和设置在凸轮外侧的限位件;凸轮和转向轴连接;限位件与驱动部电连接,当转向轴的转动的角度超过阈值时,凸轮挤压限位件,从而导致限位件被触发。凸轮和转向轴连接,使得凸轮可随转向轴转动。当转向轴的转动的角度超过阈值时,凸轮挤压限位件,从而导致限位件被触发。又由于;限位件与驱动部电连接,当限位件被触发后,控制部改变驱动部的输出,可使转向轴往回转动,可避免转向角度过大。
