Abstract
A backplate assembly for accommodating and positioning an optical unit, comprising: a backplate, a plurality of cone-shaped holes, and a plurality of positioning columns. The backplate includes a plate and a vertical lateral side which vertically surrounds the plate. The cone-shaped holes are formed in the backplate. The positioning columns are protruding from the first surface for positioning the optical unit. Each positioning column has a column body part and a ring-shaped head part forming on an end of the column body. An external diameter of the ring-shaped head part is smaller than a diameter of the column body. The ring-shaped head part of each optical unit column inserts into each cone-shaped hole through the first opening by an external force and engages with the cone-shaped hole, such that the positioning column is fixed in the backplate.
