Embodiment 1

[0021] Embodiment 1 of the present invention discloses a camera module. The camera module includes: a lens, a voice coil motor, a base, a filter, a circuit board and an image sensor. The lens is mounted on the voice coil motor.

[0022] Wherein, the base has an opposite first surface, a second surface and an inner cavity passing through the first surface and the second surface, the voice coil motor is installed on the first surface, and the second surface of the base is installed on the circuit board;

[0023] The image sensor is built into the inner cavity of the base, and is coaxially installed on the circuit board with the lens, and the optical filter is attached to the upper surface of the image sensor. The area of ​​the light sheet.

[0024] In practical applications, when the camera module focuses, the lens can pass through the inner cavity of the base and approach the image sensor driven by the voice coil motor, so as to form a clear image surface on the image sensor. ...

Embodiment 2

[0037] Referring to the first embodiment, the second embodiment is based on the first embodiment, a circuit board is provided with an accommodating cavity, and the image sensor is fixed in the accommodating cavity.

[0038] More preferably, the image sensor can be fixed in the housing cavity by insulating glue. After the image sensor is fixed in the housing cavity, it can be soldered with gold wires and preset solder pins on the circuit board to form an electrical connection. The depth of the housing cavity can be set to After the image sensor is fixed, the upper surface of the image sensor is in the same plane as the upper surface of the circuit board.

[0039] In order to enable those skilled in the art to better understand Embodiment 2 of the present invention, the following is illustrated by specific examples:

[0040] Such as image 3 Shown is a schematic structural diagram of a camera module according to Embodiment 2 of the present invention. The camera module includes:...

Embodiment 3

[0049] Embodiment 3 of the present invention discloses a mobile terminal. The mobile terminal includes a camera module. The camera module includes: a lens, a voice coil motor, a base, an optical filter, a circuit board, and an image sensor. The lens is installed In the voice coil motor, wherein,

[0050] The base has an opposite first surface, a second surface, and an inner cavity passing through the first surface and the second surface, the voice coil motor is installed on the first surface, and the second surface of the base mounted on the circuit board;

[0051] The image sensor is built into the inner cavity of the base, and is coaxially installed on the circuit board with the lens, the optical filter is attached to the upper surface of the image sensor, and the inner cavity of the base The minimum cross-sectional area in the direction perpendicular to the axis of the lens is larger than the area of ​​the optical filter.

[0052] Preferably, the lens approaches the image...

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...
