Document Type and Number:
WIPO Patent Application WO/2021/000201
Kind Code:

Abstract:
Disclosed is a compound lens module (10), comprising a lens tube (100), a lens (200) and a shading member (300), wherein the lens (200) and the shading member (300) are accommodated in the lens tube (100); the shading member (300) comprises a first supporting face (310), a second supporting face (320), and an inner wall face (330); the first supporting face (310) is close to the light incidence end; the second supporting face (320) and the first supporting face (310) are arranged oppositely in the thickness direction of the shading member (300); the inner wall face (330) is connected between the first supporting face (310) and the second supporting face (320), and the inner wall face (330) is enclosed to form a light passing hole (340); and among the projections obtained in the light incidence direction, the projection of the second supporting face (320) is located within the projection of the first supporting face (310), and a step groove (312) is provided on the first supporting face (310). By means of the compound lens module (10), the problem of the whole flatness of the first supporting face (310) of the shading member (300) thereof being low is effectively solved, such that when the shading member (300) is assembled into the compound lens module (10), the shading member (300) can better bear the lens (200), and furthermore, the arranged shading member (300) can reduce the contact area between the first supporting face (310) of the shading member and the inner wall of the lens tube (100), thereby enabling the lens (200) to be more stably arranged in the lens tube (100), and improving the performance of the compound lens module (10).
