Abstract
A projection mechanism and glasses are disclosed. The projection mechanism comprises an arc-shaped guide rail, a mounting bracket and a projection assembly. The mounting bracket is slidably arranged on the arc-shaped guide rail. The mounting bracket is provided with a through hole. The projection assembly is inserted in the through hole. The arc-shaped guide rail and the mounting bracket are respectively used to connect the rim and the temples. The mounting bracket can be located at a first position or a second position of the arc-shaped guide rail. When the mounting bracket is located at the first position of the arc-shaped guide rail, a light source output end of the projection assembly faces toward the rim. When the mounting bracket is located at the second position of the arc-shaped guide rail, the projection assembly is far away from the rim.
