Title:
PRESSING RING, LENS, CAMERA MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/195878
Kind Code:
A1
Abstract:
Disclosed are a pressing ring for a lens, a lens, a camera module and an electronic device. The pressing ring comprises an abutting ring which is annular and is used for abutting against a lens group located inside a lens tube of the lens, and a glue joint part which is connected to the abutting ring and extends in the direction away from the center of the abutting ring. The glue joint part is used for extending out of an accommodating cavity inside the lens tube and is in glue joint with the lens tube, thereby making the pressing ring be fixed on the lens cone. Since the glue joint part of the pressing ring can be in glue joint with the lens tube outside the accommodating cavity of the lens tube, glue cannot reflect stray light inside the lens tube, thereby enhancing the imaging effect of the lens.
