Each forward and reverse synchronous drive motor is connected to two horizontally arranged winding shafts through a gear assembly. Each winding shaft is provided with a forward winding shaft section and a reverse winding shaft section. A first steel strand is fixedly connected to the forward winding shaft section. After the first steel strand is wound on the forward winding shaft section for a certain length, its free end first bypasses the first annular groove of the direction-changing driving pulley and then is fixedly connected downward to the sponge driving column; a second steel strand is fixedly connected to the reverse winding shaft section. After the second steel strand is wound on the reverse winding shaft section for a certain length, its free end bypasses the fixed pulley, then bypasses the second annular groove of the direction-changing driving pulley upward, and then is fixedly connected upward to the rubber strip driving column;

[0010] Two vertical slide grooves are respectively arranged on the vertical frames on the left and right sides of the window frame along the height direction thereof, wherein two vertical slide grooves correspond to the left and right positions of the movable strip substrate located on the inner side of the glass, and the other two vertical slide grooves correspond to the left and right positions of the movable strip substrate located on the outer side of the glass; the outer ends of the two direction-changing rotating shafts of each movable strip substrate are slidably matched with the vertical slide grooves corresponding to the positions;

[0011] The forward and reverse synchronous driving motor on the left side drives the left ends of the two movable strip-shaped substrates on the inner and outer sides of the glass to move up and down respectively through the two winding shafts connected thereto, and the forward and reverse synchronous driving motor on the right side drives the right ends of the two movable strip-shaped substrates on the inner and outer sides of the glass to move up and down respectively through the two winding shafts connected thereto;

[0014] The axes of the two rubber strip driving columns on the same movable bar substrate are collinear, the axes of the two change-direction transfer shafts on the same movable bar substrate are collinear, and the axes of the two sponge driving columns on the same movable bar substrate are collinear; the axes of the two change-direction transfer shafts on the same fixed bar substrate are collinear. The two strip cleaning sliding structures are controlled and driven by two positive and negative synchronous driving motors, and the two positive and negative synchronous driving motors are provided with four winding shafts in total. The four left and right ends of the two movable bar substrates are respectively connected to the four winding shafts. The two positive and negative synchronous driving motors rotate forward or reverse at the same time, thereby driving the two movable bar substrates located on the inner and outer sides of the glass to move up and down.

After that, when the forward and reverse synchronous drive motor is controlled to drive the first steel strand to rotate forward, the first steel strand is wound around the forward winding shaft section of the winding shaft, the first steel strand becomes shorter and shorter, the movable strip substrate is lifted upward along the glass, and the reverse winding shaft section drives the second steel strand to become longer and longer. The movable strip substrate as a whole flips with the axis of the turning center shaft as the rotating axis, specifically, the upper edge of the movable strip substrate flips in the direction away from the glass, and the lower edge of the movable strip substrate flips in the direction close to the glass. The upper wiper rubber strip is driven away from the glass by the movable strip substrate, and the lower sponge strip is pressed by the movable strip substrate and moves upward in contact with the glass to wipe the cleaning agent. When the forward and reverse synchronous driving motor drives the second steel strand to reverse, the second steel strand is wound around the reverse winding shaft section of the winding shaft, and the reverse winding shaft section drives the second steel strand to become shorter and shorter, and the movable strip substrate moves downward along the glass, and the movable strip substrate as a whole flips with the axis of the change-of-direction rotating shaft as the rotating axis. Specifically, the upper edge of the movable strip substrate flips toward the direction approaching the glass, and the lower edge of the movable strip substrate flips toward the direction away from the glass. The lower sponge strip is driven away from the glass by the movable strip substrate, and the upper wiper rubber strip is squeezed by the movable strip substrate and moves downward in contact with the glass to perform the wiper work.
