The invention discloses an electric working vehicle capable of automatically controlling lifting height, which comprises a base platform, a lifter, a working platform, a controller, a motor, a transmission shaft, a second clutch and a second driving belt wheel, wherein a first driving belt wheel and a first clutch are both connected with the transmission shaft, a first driven belt wheel is connected with an axle, and wheels are respectively connected with two ends of the axle; a second driving belt wheel is connected with the two second driven belt wheels through belts, the second driven belt wheels are connected with the second clutch, and the two second driven belt wheels are correspondingly connected with worms of the lifters. After receiving the signal, the controller controls the motor, and the transmission shaft rotates to drive the second driven belt wheels, so that a screw shaft of the lifter is driven to vertically move. During working, pressure generated after the working platform makes contact with a power battery is transmitted to the screw shaft, a pressure sensor detects a pressure signal and feeds the pressure signal back to the controller, so that the lifting state of the working platform of the electric working vehicle is adjusted, and the lifting height of the working platform is accurately controlled.

    本发明公开一种自动控制升降高度的电动作业车,包括底座平台、升降器、工作平台、控制器、电机、传动轴、第二离合器、第二主动带轮,第一主动带轮和第一离合器均与所述传动轴连接,第一从动带轮与车轴连接,车轮分别与车轴的两端连接;第二主动带轮通过皮带与两个所述第二从动带轮连接,第二从动带轮与第二离合器连接,两个第二从动带轮对应与升降器的蜗杆连接。控制器接收到信号后,控制电机、传动轴转动带动第二从动带轮,从而带动升降器的螺杆轴竖直运动。螺杆轴下端安装压力传感器,工作时,工作平台与动力电池接触后的压力传递给螺杆轴,压力传感器检测压力信号并反馈给控制器,调整电动作业车工作平台升降状态,精准控制其举升高度。
