Abstract

An optical lens includes a transparent portion and a flange portion surrounding the transparent portion. The flange portion includes a connecting portion, a transition portion, and an edge portion. The connecting portion is coupled between the transparent portion and the transition portion. The transition portion is coupled between the connecting portion and the edge portion. The flange portion defines a V-shaped groove. The V-shaped groove surrounds the transparent portion.

First claim

What is claimed is:

1 . An optical lens comprising:
a transparent portion; and a flange portion surrounding the transparent portion; wherein: the flange portion comprises a connecting portion, a transition portion, and an edge portion; the connecting portion is coupled between the transparent portion and the transition portion; the transition portion is coupled between the connecting portion and the edge portion; the flange portion defines a V-shaped groove; and the V-shaped groove surrounds the transparent portion.

2 . The optical lens of claim 1 , wherein:
an inner wall of the V-shaped groove is a textured V-shaped surface.

3 . The optical lens of claim 2 , wherein:
the transition portion comprises a first transition surface facing an object side and a second transition surface opposite the first transition surface; the V-shaped groove is recessed from the first transition surface toward the second transition surface; the V-shaped groove comprises an apex point; the edge portion comprises a first edge surface facing an image side and a second edge surface facing the object side; the first edge surface is coupled to one end of the V-shaped surface; the second edge surface is coupled to the second transition surface; the apex point extends beyond the second edge surface; and a depth of the V-shaped groove is greater than a distance between the first edge surface and the second edge surface of the edge portion.

4 . The optical lens of claim 1 , wherein:
an opening angle of the V-shaped groove is 55-100 degrees.

5 . The optical lens of claim 2 , wherein:
the connecting portion comprises a first connecting surface coupled to the V-shaped surface; and a surface angle of the first connecting surface is 15-25 degrees.

6 . The optical lens of claim 5 , wherein:
the first connecting surface is a polished surface.

7 . The optical lens of claim 5 , wherein:
a width of the first connecting surface is 30-100 microns.

8 . A lens assembly comprising:
a lens barrel; a first lens; a second lens; and an optical lens, the first lens, the optical lens, and the second lens arranged in sequence from an object side to an image side and fixedly housed in the lens barrel, the optical lens comprising:
a transparent portion; and
a flange portion surrounding the transparent portion; wherein:
the flange portion comprises a connecting portion, a transition portion, and an edge portion; the connecting portion is coupled between the transparent portion and the transition portion; the transition portion is coupled between the connecting portion and the edge portion; the flange portion defines a V-shaped groove; and the V-shaped groove surrounds the transparent portion.

9 . The lens assembly of claim 8 , wherein:
an inner wall of the V-shaped groove is a textured V-shaped surface.

10 . The lens assembly of claim 9 , wherein:
the transition portion comprises a first transition surface facing an object side and a second transition surface opposite the first transition surface; the V-shaped groove is recessed from the first transition surface toward the second transition surface; the V-shaped groove comprises an apex point; the edge portion comprises a first edge surface facing an image side and a second edge surface facing the object side; the first edge surface is coupled to one end of the V-shaped surface; the second edge surface is coupled to the second transition surface; the apex point extends beyond the second edge surface; and a depth of the V-shaped groove is greater than a distance between the first edge surface and the second edge surface of the edge portion.

11 . The lens assembly of claim 10 , wherein:
an opening angle of the V-shaped groove is 55-100 degrees.

12 . The lens assembly of claim 11 , wherein:
the connecting portion comprises a first connecting surface coupled to the V-shaped surface; and a surface angle of the first connecting surface is 15-25 degrees.

13 . The lens assembly of claim 12 , wherein:
the first connecting surface is a polished surface.

14 . The lens assembly of claim 13 , wherein:
a width of the first connecting surface is 30-100 microns.

15 . The lens assembly of claim 14 , wherein the optical lens further comprises a first shading film and a second shading film, and the first shading film is located between the first lens and the first lens. Between the two lenses, the second shading film is located between the optical lens and the second lens.

16 . An electronic device comprising a body and a lens assembly arranged in the body, the lens assembly comprising:
a lens barrel; a first lens; a second lens; and an optical lens, the first lens, the optical lens, and the second lens arranged in sequence from an object side to an image side and fixedly housed in the lens barrel, the optical lens comprising:
a transparent portion; and
a flange portion surrounding the transparent portion; wherein:
the flange portion comprises a connecting portion, a transition portion, and an edge portion; the connecting portion is coupled between the transparent portion and the transition portion; the transition portion is coupled between the connecting portion and the edge portion; the flange portion defines a V-shaped groove; and the V-shaped groove surrounds the transparent portion.
