Problems solved by technology

Traditionally, the imaging lens design with small object-side size will reduce the object-side thickness of the receiving member, which will cause the receiving member to be easily deformed by the extrusion of the optical element after loading the optical element, thus increasing the risk of assembly failure
On the other hand, in order to correspond to the large-size photosensitive element, the length and weight of the imaging lens have been greatly increased, which makes the imaging device prone to tilt when maintaining or moving the imaging lens, which in turn causes the optical axis to shift, affecting Image quality

Abstract

An imaging lens, an image capturing device and an electronic device are provided, the imaging lens includes a plurality of optical elements and an accommodating member, and the accommodating member accommodates the optical elements. The housing member includes a tapered light shielding sheet and a lens barrel. The conical anti-dazzling screen comprises an outer side part and a conical part, and the conical part is connected with the outer side part. The conical part comprises a conical structure which is gradually shrunk from the outer side part to the object side or the image side along the optical axis. The lens barrel can be arranged on the object side or the image side of the conical part. The optical elements may include an object-side-most optical element, an image-side-most optical element, and at least one optical element, and the tapered structure of the tapered portion is only in physical contact with one of the lens barrel, an object side of the object-side-most optical element, and an image side of the image-side-most optical element. Therefore, the characteristic of small object side size can be achieved, and deformation of the conical anti-dazzling screen can be avoided.

Description

technical field [0001] The disclosure relates to an imaging lens and an image capturing device, and in particular to an imaging lens and an image capturing device applied to a portable electronic device. Background technique [0002] In order to meet the needs of the modern consumer electronics market, the trend of imaging lenses is to develop in the direction of small object-side size, large aperture, and corresponding to large-size and high-pixel photosensitive elements. Among them, the object-side size is an important indicator. The smaller object-side size can reduce the area of ​​the product surface that needs to be opened for the imaging lens, which means that the use area of ​​other devices can be increased, such as the display screen. However, there are many problems to be overcome in the manufacture of imaging lenses with small object-side size, and the most urgent problem comes from the assembly process. In practice, the imaging lens has a housing component for lo...
