Camera module and mobile terminal

Abstract

The embodiment of the invention provides a camera module and a mobile terminal. The camera module comprises a lens, a voice coil motor, a base, an optical filter, a circuit board and an image sensor, wherein the lens is arranged on the voice coil motor; the base is provided with a first surface and a second surface which are opposite to each other, and an inner cavity passing through the first surface and the second surface; the voice coil motor is arranged on the first surface; the second surface of the base is arranged on the circuit board; the image sensor is embedded into the inner cavity of the base, and coaxially arranged on the circuit board together with the lens; the optical filter is attached to an upper surface of the image sensor; and a minimum cross-sectional area of the inner cavity of the base in a direction vertical to the axis direction of the lens is larger than the area of the optical filter. Through application of the camera module and the mobile terminal, the optical filter is prevented from being cracked by extrusion of the base; the space for fixing the optical filter is saved for the base simultaneously; more design space is provided for the lens; the optical length can be shortened in order to lower the height of the camera module; and the development of the mobile terminal to lightness, thinness and portability is facilitated.

Description

technical field [0001] The invention relates to the technical field of optical photography, in particular to a camera module and a mobile terminal. Background technique [0002] With the advancement of electronic technology, various electronic products, such as mobile terminals, computers and electronic watches, are usually provided with camera modules. For the convenience of carrying or installation, various electronic products tend to be thinner and smaller. [0003] In order to meet the requirements of thin, light and convenient electronic products, the structural space of the product is getting smaller and smaller, and the corresponding camera module is an optical product, and the smaller the structure, the greater the impact on the optical performance, such as figure 1 As shown, it is a schematic structural diagram of an existing camera module. The camera module includes a lens 1, a voice coil motor 2, an optical filter 3, a base 4, an image sensor 5 and a circuit boar...

AI Technical Summary

Problems solved by technology

[0007] The embodiment of the present invention provides a camera module and a mobile terminal to solve the problems that the base structure of the current camera module is not strong enough to cause the filter to break and the total height of the camera module is too high, which is not conducive to the development of thin and portable electronic products
