Title:
LENS STRUCTURE AND ELECTRONIC DEVICE USING THE LENS STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/128180
Kind Code:
A1
Abstract:
A lens structure and an electronic device using the lens structure. An electronic device comprises a lens structure. The lens structure comprises a lens barrel (1) and a lens assembly (2) accommodated in the lens barrel (1). The lens barrel (1) comprises a top wall (11) having a light through hole (001) and a barrel wall (12) extending from the top wall (11) in a bended manner, the top wall (11) comprises an upper surface (112), a lower surface (111) and an inner wall surface (110), and the inner wall surface (110) comprises a first inclined surface (117) extending from the upper surface (112) toward the optical axis (oo') and the image side, a second inclined surface (116) extending from the first inclined surface (117) toward the optical axis (oo') and the image side, a connecting surface (115) extending from the second inclined surface (116) away from the optical axis (oo'), a third inclined surface (114) extending from the connecting surface (115) away from the optical axis (oo') and the object side, and a fourth inclined surface (113) connecting the third inclined surface (114) and the lower surface (112). The lens structure further comprises a light-shielding sheet (4) sandwiched between the lens assembly (2) and the lower surface (111), the light-shielding sheet (4) is provided with a light-blocking section (41), and the light-blocking section (41) passes through an extension line of the fourth inclined surface (113) and extends toward the optical axis (oo'). The light effect of stray light generated by a lens structure due to the front position of a diaphragm can be reduced, thereby improving the imaging quality of the lens structure.
