Embodiment Construction

[0026] The principles and embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 1 to Figure 4 As shown, the first embodiment of the present invention shows a fixed-focus anti-shake camera module. The fixed-focus anti-shake camera module includes the following components: upper cover 001, lens 002, magnet 003, lens holder 004, four deflection coils 005, coil holder 006, image sensor chip 007, circuit board with spring arm 008, Base 009.

[0028] The upper cover 001 and the base 009 are connected to form a housing. When the upper cover 001 and the base 009 are assembled into the housing, the through holes provided on the opposite surfaces of the upper cover 001 and the base 009 form a light channel. In this embodiment, the casing is a square casing.

[0029] A lens assembly and a driving assembly for controlling the deflection movement of the lens assembly to realize anti-shake are arrang...

Abstract

The invention discloses an anti-shake camera module and an anti-shake camera device. The camera module comprises a shell, a lens assembly and a driving assembly, wherein the shell consists of an uppercover and a base, the lens assembly is movably fixed in the shell through a first spring piece, the driving assembly controls the lens assembly to deflect in two orthogonal directions perpendicular to a plane of an optical axis, the driving assembly comprises an annular magnet and deflection coils, the annular magnet is coaxial with the lens assembly, two polarities of the annular magnet face twoends of the lens assembly respectively and are used for driving the lens assembly to deflect, the deflection coils are arranged on the periphery of the annular magnet in two orthogonal directions, face different polarities of the outer side of the annular magnet and are parallel to each other, and the current directions of the two wires are opposite. The camera module is advantaged in that electromagnetic efficiency is high, and the size is small.

Description

technical field [0001] The present invention relates to a camera module, in particular to a fixed-focus or focus anti-shake camera module, and a camera device using the camera module. Background technique [0002] With the development of smart phones and smart hardware industries, people's daily life, work, entertainment and other aspects of shooting are more and more demanding, and the requirements for camera functions are getting higher and higher, and it is necessary to focus faster, more sensitive, It can see farther and clearer, and has an anti-shake function when shooting handheld. The camera is also smaller, which is easy to control the size of the electronic product itself, and is easier to carry. There are also higher requirements for the motor that controls the lens. Among them, the motors on the market have their own shortcomings, such as low electromagnetic efficiency, heavy weight, difficulty in mass production, difficulty in focusing, slightly larger size, no ...
