Title:
LENS ASSEMBLY, LENS MODULE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/126660
Kind Code:
A1
Abstract:
A lens assembly (10), a lens module (100), and an electronic device (1000). The lens assembly (10) comprises: a lens barrel (12) having an inner cavity (122), an object side end of the lens barrel (12) being provided with a window (124) communicated with the inner cavity (122); a first lens (14), a part of the first lens (14) being provided in the inner cavity (122) of the lens barrel (12) and abutting against an inner wall of the lens barrel (12), and at least a part of the object side surface of the first lens (14) protruding out of the window (124) of the lens barrel (12); and a second lens (16), connected and fixed to the object side surface of the first lens (14). The lens assembly (10) achieves the purpose of a small head of the lens assembly (10) by forming an L1 lens together by the first lens (14) and the second lens (16). Compared with the whole L1 lens, the thickness of the first lens (14) is reduced, and when the first lens (14) is manufactured, the adverse effect of an ejection structure on demolding of the first lens (14) can be avoided, so as to enable the eccentric value of the first lens (14) to be smaller and more stable, the thickness of the first lens (14) is uniform, a plastic shrinkage ratio of the first lens (14) is reduced, and the shape of the non-spherical surface of the formed first lens (14) is closer to a design value.
