Abstract: A lens barrel is provided, including: a lens barrel body which is hollow and open at both ends, and a support wall bending and extending inwardly from an object-side end of the lens barrel body and enclosing a light-through hole. An image-side surface of the support wall is provided with extinction regions spaced apart from each other along a circumferential direction of the support wall. Each extinction region includes linear extinction strips protruding from the image-side surface, and the linear extinction strips are all disposed in each extinction region. Each linear extinction strip extends from one end of the image-side surface of the support wall adjacent to the lens barrel body to one end thereof adjacent to the optical axis, and adjacent two linear extinction strips are spaced apart from each other to form a vent slot. The lens barrel and lens module of the present disclosure are more reliable.

Abstract: The present application provides a lens module, including a lens barrel and a lens. The lens barrel includes a first barrel wall enclosed to form a light-through hole and a second barrel wall bent and extended from the first barrel wall. The first barrel wall includes a first wall arranged around the light-through hole and a second wall connecting the first wall to the second barrel wall. The first wall and the lens are spaced apart to form a first gap. The support portion is abutted against the second wall. The first barrel wall is provided with a recess formed by recessed from the second wall. One end of the recess is extended to a junction between the second wall and the second barrel wall, and the other end thereof is in communication with the first gap. This lens module has good exhaust performance and stable optical performance.
