Anti-electrophoretic liquid infiltration angle adjuster and assembly method therefor

Abstract

The present invention relates to an anti-electrophoretic liquid infiltration angle adjuster, comprising a gear toothed plate and a gear ring toothed plate which can rotate relative to each other; and a clamping ring for holding the gear toothed plate and the gear ring toothed plate together, one end of the clamping ring being fixedly connected to the gear ring toothed plate, and the other end of the clamping ring being bent towards the gear toothed plate so as to form a clearance fit with the gear toothed plate. The present invention further relates to an assembly method for the anti-electrophoretic liquid infiltration angle adjuster. According to the anti-electrophoretic liquid infiltration angle adjuster of the present invention, a gap is controlled by means of bending and shaping of the clamping ring, and impurities such as electrophoretic liquid are prevented from entering the interior of the angle adjuster, thereby preventing the normal function of the angle adjuster from being affected. The impurities such as electrophoretic liquid may be further prevented from entering the interior of the angle adjuster by means of controlling a gap between a drive cam and the gear toothed plate. Gaps at two ends of a cover cap is controlled by means of selecting a metal cover cap to be the cover cap, and the impurities such as electrophoretic liquid may be further prevented from entering the interior of the angle adjuster.
