Abstract

An optical lens includes a first lens and a second lens facing the first lens. The first lens includes a first flange structure. The first flange structure includes a first surface facing the second lens. The first surface includes a first positioning portion. The second lens includes a second flange structure. The second flange structure includes a second surface facing the first lens. The second surface includes a second positioning portion. The first positioning portion engages with the second positioning portion.

First claim

What is claimed is:

1 . An optical lens comprising:
a first lens; and a second lens facing the first lens; wherein: the first lens comprises a first flange structure, the first flange structure comprises a first surface facing the second lens, and the first surface comprises a first positioning portion; the second lens comprises a second flange structure, the second flange structure comprises a second surface facing the first lens, and the second surface comprises a second positioning portion; and the first positioning portion engages with the second positioning portion.

2 . The optical lens of claim 1 , wherein:
the first positioning portion is one of a protrusion and a groove, and the second positioning portion is the other one of the protrusion and the groove.

3 . The optical lens of claim 2 , wherein:
an outer surface of the protrusion and an inner surface of the groove are flat smooth surfaces.

4 . The optical lens of claim 2 , wherein:
the rest of the first surface besides the first positioning portion and the rest of the second surface besides the second positioning portion are rough surfaces.

5 . The optical lens of claim 1 , further comprising a third lens, wherein:
the third lens is located on a side of the second lens facing away from the first lens; the second flange structure further comprises a third surface facing away from the second surface, and the third surface comprises a third positioning portion; the third lens comprises a third flange structure, the third flange structure comprises a fourth surface facing the second lens, and the fourth surface comprises a fourth positioning portion; the third positioning portion is one of a protrusion and a groove, and the fourth positioning portion is the other one of the protrusion and the groove; and the third positioning portion engages with the fourth positioning portion.

6 . The optical lens of claim 1 , wherein:
the first lens comprises a first lens portion coupled to the first flange structure; the second lens comprises a second lens portion coupled to the second flange structure; and the first lens portion and the second lens portion are opposite each other.

7 . The optical lens of claim 1 , further comprising a lens barrel, wherein:
the first lens and the second lens are sequentially received in the lens barrel along an axial direction of the lens barrel.

8 . The optical lens of claim 7 , wherein:
the lens barrel comprises a first lens barrel portion and a second lens barrel portion coupled to the first lens barrel portion; a diameter of the first lens barrel portion is smaller than a diameter of the second lens barrel portion; the first lens is received in the first lens barrel portion; and a portion of the second lens is received in the first lens barrel portion, and another portion of the second lens is received in the second lens barrel portion.

9 . The optical lens of claim 1 , further comprising a light-shielding sheet, wherein:
the light-shielding sheet is located between the first flange structure and the second flange structure.

10 . An electronic device comprising an optical lens, the optical lens comprising:
a first lens; and a second lens facing the first lens; wherein: the first lens comprises a first flange structure, the first flange structure comprises a first surface facing the second lens, and the first surface comprises a first positioning portion; the second lens comprises a second flange structure, the second flange structure comprises a second surface facing the first lens, and the second surface comprises a second positioning portion; and the first positioning portion engages with the second positioning portion.

11 . The electronic device of claim 10 , wherein: a
the first positioning portion is one of a protrusion and a groove, and the second positioning portion is the other one of the protrusion and the groove.

12 . The electronic device of claim 11 , wherein:
an outer surface of the protrusion and an inner surface of the groove are flat smooth surfaces.

13 . The electronic device of claim 11 , wherein:
the rest of the first surface besides the first positioning portion and the rest of the second surface besides the second positioning portion are rough surfaces.

14 . The electronic device of claim 10 , wherein:
the optical lens further comprises a third lens; the third lens is located on a side of the second lens facing away from the first lens; the second flange structure further comprises a third surface facing away from the second surface, and the third surface comprises a third positioning portion; the third lens comprises a third flange structure, the third flange structure comprises a fourth surface facing the second lens, and the fourth surface comprises a fourth positioning portion; the third positioning portion is one of a protrusion and a groove, and the fourth positioning portion is the other one of the protrusion and the groove; and the third positioning portion engages with the fourth positioning portion.

15 . The electronic device of claim 10 , wherein:
the first lens comprises a first lens portion coupled to the first flange structure; the second lens comprises a second lens portion coupled to the second flange structure; and the first lens portion and the second lens portion are opposite each other.

16 . The electronic device of claim 10 , wherein:
the optical lens further comprises a lens barrel; the first lens and the second lens are sequentially received in the lens barrel along an axial direction of the lens barrel.

17 . The electronic device of claim 16 , wherein:
the lens barrel comprises a first lens barrel portion and a second lens barrel portion coupled to the first lens barrel portion; a diameter of the first lens barrel portion is smaller than a diameter of the second lens barrel portion; the first lens is received in the first lens barrel portion; and a portion of the second lens is received in the first lens barrel portion, and another portion of the second lens is received in the second lens barrel portion.

18 . The electronic device of claim 10 , wherein:
the optical lens further comprises a light-shielding sheet; the light-shielding sheet is located between the first flange structure and the second flange structure.
