LENS AND LENS MODULE INCLUDING THE SAME
The present disclosure relates to the field of optical imaging technologies, and provides a lens and a lens module including the lens. The lens includes: an optical portion located at a central position; a bearing portion surrounding the optical portion; and a plurality of reinforcing portions embedded in the bearing portion for reinforcing rigidity of the bearing portion. The plurality of reinforcing portions is spaced apart from each other around an optical axis. The lens and the lens module including the same provided by the present disclosure can enhance the ability to resist deformation of the lens, and improve the assembly stability of the lens module, thereby improving the yield of the lens module.
1 . A lens, comprising:
an optical portion located at a central position;
a bearing portion surrounding the optical portion; and
a plurality of reinforcing portions embedded in the bearing portion for reinforcing rigidity of the bearing portion,
wherein the plurality of reinforcing portions is spaced apart from each other around an optical axis.
2 . The lens as described in claim 1 , wherein the plurality of reinforcing portions is equally spaced around the optical axis.
3 . The lens as described in claim 1 , wherein the bearing portion comprises a first surface and a second surface that are opposite to each other, the bearing portion is provided with a plurality of recessed portions each formed by recessing from the first surface towards the second surface, and the plurality of reinforcing portions is fixed in the plurality of recessed portions.
4 . The lens as described in claim 3 , wherein the bearing portion further comprises a peripheral surface connecting the first surface with the second surface, and each of the plurality of recessed portions extends from the peripheral surface towards the optical axis.
5 . The lens as described in claim 1 , wherein the bearing portion comprises a first surface and a second surface that are opposite to each other, and the plurality of reinforcing portions is located between the first surface and the second surface in a direction parallel to the optical axis and not exposed out of the first surface.
6 . The lens as described in claim 5 , wherein the plurality of reinforcing portions has equal distances from the first surface and the second surface in the direction parallel to the optical axis.
7 . The lens as described in claim 1 , wherein each of the plurality of reinforcing portions is made of a metal material.
8 . The lens as described in claim 7 , wherein the bearing portion and the plurality of reinforcing portions are formed into one piece.
9 . A lens module, comprising the lens as described in claim 1 .
10 . The lens module as described in claim 9 , wherein the plurality of reinforcing portions is equally spaced around the optical axis.
11 . The lens module as described in claim 9 , wherein the bearing portion comprises a first surface and a second surface that are opposite to each other, the bearing portion is provided with a plurality of recessed portions each formed by recessing from the first surface towards the second surface, and the plurality of reinforcing portions is fixed in the plurality of recessed portions.
12 . The lens module as described in claim 11 , wherein the bearing portion further comprises a peripheral surface connecting the first surface with the second surface, and each of the plurality of recessed portions extends from the peripheral surface towards the optical axis.
13 . The lens module as described in claim 9 , wherein the bearing portion comprises a first surface and a second surface that are opposite to each other, and the plurality of reinforcing portions is located between the first surface and the second surface in a direction parallel to the optical axis and not exposed out of the first surface.
14 . The lens module as described in claim 13 , wherein the plurality of reinforcing portions has equal distances from the first surface and the second surface in the direction parallel to the optical axis.
15 . The lens module as described in claim 9 , wherein each of the plurality of reinforcing portions is made of a metal material.
16 . The lens module as described in claim 9 , wherein the bearing portion and the plurality of reinforcing portions are formed into one piece.
17 . A lens module as described in claim 9 , comprising:
a lens barrel having a receiving space; and
an optical assembly received in the receiving space,
wherein the optical assembly comprises a first lens close to an object side, a light shading plate provided at an image side of the first lens, and the lens being provided between the first lens and the shading plate.
