The invention discloses a direct current charging pile for an automobile, which comprises a box body, a display screen, an indicating lamp, a support plate, an upper dovetail guide rail, a lower dovetail guide rail, an upper dovetail seat, a lower dovetail seat, a support rod, a guide wheel and a stranded wire part, and is characterized in that the front part of the box body is provided with the display screen and the indicating lamp, and the rear part of the box body is fixedly provided with the support plate; two vertical upper dovetail guide rails are symmetrically fixed to the upper portion of the rear end of the supporting plate, and a vertical lower dovetail guide rail is fixed to the bottom of the rear end of the supporting plate. The double-rod motor is controlled to rotate positively and negatively, so that the upper dovetail seat and the lower dovetail seat can get close to each other and get away from each other, a charging wire can be released and automatically twisted by using the guide wheel, and meanwhile, the charging wire is guided by the guide wheel, so that the charging efficiency is improved. The phenomenon that the charging wire is abnormally twisted and wound due to the fact that the charging wire is not stored in time and inaccurately can be avoided, meanwhile, friction between the charging wire and the ground can be avoided to a certain degree, and then the service life of the charging wire is prolonged.
本发明公开了一种汽车用直流充电桩,包括箱体、显示屏、指示灯、支撑板、上燕尾导轨、下燕尾导轨、上燕尾座、下燕尾座、支撑杆、导向轮、绞线部分,所述箱体前部安装有显示屏和指示灯,所述箱体后部固定有支撑板,所述支撑板后端上部对称固定有两竖直的上燕尾导轨,且后端底部固定有竖直的下燕尾导轨。本发明通过控制双杆电机正反转动,能够使得上燕尾座和下燕尾座相互靠近和相互远离,从而能够利用导向轮对充电线进行释放和自动绞线,同时再经过导向轮对充电线的引导,即能够避免出现因为充电线存放的不及时和不准确而产生充电线的异常扭曲和缠绕现象,同时也能够在一定程度上避免充电线与地面的摩擦,继而延长充电线的使用寿命。
