Title:
LENS MODULE
Document Type and Number:
WIPO Patent Application WO/2021/000193
Kind Code:
A1
Abstract:
Provided is a lens module; a lens cylinder (1) comprises a top wall (11) having an optical aperture (111) and a cylinder wall (12) bent and extended from the edge of the top wall (11); the top wall (11) and the cylinder wall (12) are connected and enclosed to form a cavity; a lens set (2) is accommodated in the cavity; the lens set (2) comprises a contoured lens; the contoured lens comprises a side surface (241) connected to an object side surface (242) and an image side surface (243); the side surface (241) comprises a first abutting surface (2411) connected to the object side surface (242), and the first abutting surface (2411) and an optical axis (00') are arranged at an angle; the cylinder wall (12) comprises an inner surface (121) adjacent to the optical axis (00'); the inner surface (121) comprises a second abutting surface (1211) which is opposite to and parallel to the first abutting surface (2411); the distance between the first abutting surface (2411) and the second abutting surface (1211) is greater than 0 μm and less than or equal to 3 μm. When the lens is subjected to force and deformed, if the amount of deformation exceeds the distance between the first abutting surface (2411) and the second abutting surface (1211), the first abutting surface (2411) abuts against the second abutting surface (1211) so as to limit further deformation of the lens, improving the stability of the lens module and ensuring the imaging quality of the lens module.
