Title:
LENS MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/258340
Kind Code:
A1
Abstract:
A lens module (10) and an electronic device (1). The lens module (10) comprises a lens barrel (100), a lens group (200), and a pressing ring (300). The lens barrel (100) is provided with a cavity (110); both the lens group (200) and the pressing ring (300) are located in the cavity (110); and the pressing ring (300) is connected to the lens barrel (100). The pressing ring (300) comprises a body (310) and protrusions (320). The body (310) comprises an object side surface (311); the object side surface (311) comprises an abutting surface (3111) and a non-abutting surface (3112); the abutting surface (3111) is far away from an optical axis (400) with respect to the non-abutting surface (3112); the abutting surface (3111) abuts against the lens group (200); and the non-abutting surface (3112) is provided with protrusions (320), and the protrusions (320) are round protrusions (320). The provision of the protrusions (320) can reduce the stray light exiting from the lens barrel (100) because multiple reflections by the surface of the protrusions (320) would cause energy loss to the light irradiated on the pressing ring (300), so that the imaging quality of the lens module (10) and the electronic device (1) using the lens module (10) is improved.
