The invention discloses a vertical electric tailboard, and belongs to the technical field of truck lifting tailboards. The device structurally comprises a lifting assembly, a lower door assembly, a left side inner stand column, a left side outer stand column, an upper door sliding block, an upper door connecting rod, an upper door hinge support, a motor, a speed reducer, a gearbox, an upper cross beam, an upper door assembly, a right side inner stand column, a right side outer stand column, a lead screw lower supporting bearing assembly, a lifting nut assembly, a lead screw, a lower door opening and closing rope, a lower door opening and closing nut assembly and an upper door opening and closing rope. The bearing assembly and the stop ring are supported on the lead screw. A lead screw transmission mechanism is utilized, the novel vertical type electric tail plate is provided, lifting, opening and closing of a lower door and opening and closing movement of an upper door are controlled through vertical operation of three nuts on a lead screw, and the lifting movement of the lower door is achieved in the mode that a lifting nut assembly drives a lower door assembly through a lifting assembly. The lower door opening and closing movement is that the lower door opening and closing nut assembly is connected to the lower door assembly through a rope to achieve opening and closing of the lower door, and the upper door opening and closing movement is that the upper door opening and closing nut assembly is connected to the upper door assembly through a rope to achieve opening and closing of the upper door. According to the invention, an external stop ring structure is arranged, so that the opening and closing of the upper door can be manually controlled. The invention has the beneficial effects that a full-electric control and auxiliary manual control system is adopted, the operation is simple, the self-locking performance is good, the safety is high, the service life is long, the transmission is stable, the noise is low, and the compatibility with the truck is good.
