Problems solved by technology

Therefore, the runners required for injection molding also need to be set very small, making the injection process difficult
At the same time, due to the small thickness of the flange structure, it is difficult for the injection material to completely fill the mold, which may cause the lens profile to deviate from the design value, resulting in defective lenses

Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or inte...

Abstract

The invention provides an optical lens. The optical lens comprises a first lens and a second lens, the first lens and the second lens are oppositely arranged, the first lens comprises a first flange structure, the first flange structure comprises a first surface facing the second lens, and the first surface is provided with a first positioning part; the first lens comprises a first flange structure, the second lens comprises a second flange structure, the second flange structure comprises a second surface facing the first lens, a second positioning part is arranged on the second surface, the first positioning part is one of a convex block and a groove, and the second positioning part is the other one of the convex block and the groove. And the first positioning part is matched with the second positioning part. The optical lens provided by the invention is easy to form. The invention further provides a lens module applying the optical lens and an electronic device.

Description

technical field [0001] The invention relates to the field of electronics and optical devices, in particular to an optical lens, a lens module and an electronic device using the optical lens. Background technique [0002] With the development of electronic products in the direction of thinner and lighter, the optical lenses in electronic products are also getting thinner and thinner. An optical lens generally includes a lens barrel and lenses arranged stacked in the lens barrel. Each lens includes a flange structure at an edge. [0003] Usually, the flange generally has a smooth bump on the structure, and two adjacent lenses are butted through their respective bumps. Since the bump occupies a certain thickness of the flange structure, the thickness of the flange structure itself is reduced, especially when the optical lens is developed towards a lighter and thinner direction, so that the thickness of the flange structure itself needs to be reduced to a smaller within range...
