Title:
OPTICAL LENS FOCUSING ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2018/219237
Kind Code:
A1
Abstract:
An optical lens focusing assembly, comprising: an outer lens barrel (211), an outer optical lens (212) fixed to the outer lens barrel, an inner lens barrel (214), an inner optical lens (217) fixed to the inner lens barrel, and positioning features; at least one inclined groove (213) is provided on the side wall of the outer lens barrel; the inner lens barrel is provided inside the outer lens barrel; the positioning features and the inclined grooves have a one-to-one correspondence; one end of each positioning feature is fixed to the side wall of the inner lens barrel, and the other end extends through the inclined groove and can slide in the inclined groove; as the optical lens focusing assembly comprises the outer lens barrel and the inner lens barrel, the outer lens barrel is provided with the inclined groove inclined at a certain angle, and the side wall of the inner lens barrel is provided with the positioning features extending into the inclined groove, the positioning feature can slide in the inclined groove. In the process of the positioning feature sliding from bottom to top or from top to bottom in the inclined groove, the positioning feature drives the inner lens barrel to move, so that the distance between the outer optical lens and the inner optical lens becomes adjustable, thereby realizing the focusing of an optical assembly of a virtual reality device.
