Lens module, image capturing device and electronic equipment

Abstract

The invention relates to a lens module, which comprises a lens barrel and a lens group accommodated in the lens barrel, wherein the lens barrel is provided with an object side end, an image side end and a light through hole penetrating through the object side end and the image side end along an optical axis; the lens group comprises a first lens, wherein the first lens is close to the object sideand is provided with a first main body part used for imaging and a first fixing part arranged around the first main body part, and the first fixing part is provided with a first surface connected withthe hole wall of the light through hole; the part, exposed out of the light through hole, of the first surface and the hole wall of the light through hole form a first connecting groove, the first connecting groove is filled with colloid, and the colloid adheres to the first lens and the hole wall of the light through hole. According to the lens module, the fixing mode of the first lens is changed, so that the front end of the lens cone can be canceled, the axial distance from the first lens to the screen is reduced, the opening size of the screen of the electronic equipment can be reduced, and a better full-screen effect is achieved. The invention also relates to an image capturing device and an electronic device.

Description

technical field [0001] The invention relates to the technical field of lens manufacturing, in particular to a lens module, an imaging device and electronic equipment. Background technique [0002] When a traditional mobile device is designed with a full screen, it usually chooses to open a small hole on the screen to allow light to penetrate to the lens below the screen. [0003] However, the inventor found in the process of implementing the conventional technology that: the wall of the lens barrel at the object-side end usually extends inward along the radial direction of the lens barrel, so as to realize the function of shading and supporting the lens in the lens barrel. However, the part of the wall that extends inward is usually thicker, so in order to facilitate the incident light to the lens below the screen, the opening on the screen is usually made larger, which will easily affect the design of the full screen and damage the appearance of the screen.
