Camera module motor, camera module and electronic equipment

Abstract

The application discloses a camera module motor, camera module and electronic equipment, wherein the camera module motor includes a housing, an upper elastic piece, a lens carrier, a coil, a lower elastic piece and a base, and the housing and the base are fitted together A hollow storage cavity is formed, and the upper elastic piece, the lens carrier and the lower elastic piece are located in the storage cavity, and the lens carrier is accommodated in the lens; the coil is wound on the surface of the lens casing, and is located between the lens casing and the casing. Between the dust-proof walls; the dust-proof walls of the housing are magnetic, which can provide the magnetic field needed for the coil to realize the focusing function of the camera module, so that there is no need to separately install a magnet in the storage cavity , which solves the problem that the camera module motor has a large volume due to the large space occupied by the magnet. And because the coil is wound on the surface of the lens housing and located between the lens housing and the dustproof wall of the housing, it is beneficial to further reduce the volume of the camera module motor.

Description

technical field [0001] The present application relates to the technical field of imaging equipment, and more specifically, to a camera module motor, camera module and electronic equipment. Background technique [0002] The camera module motor is an essential device for the camera module to realize the focusing function. The structure reference of the camera module motor figure 1 with figure 2 , figure 1 It is a schematic cross-sectional structure diagram of a camera module motor in the prior art, figure 2 for figure 1 The schematic diagram of the split structure of the camera module motor shown, the camera module motor includes a housing 1, an upper elastic piece 2, a magnet 3, a lens carrier 4, a coil 5, a lower elastic piece 6 and a base 7, wherein the coil 5 is wound on The outside of the lens carrier 4 containing the lens. Since the energized conductor will move in the magnetic field, when a certain amount of current is passed into the coil 5, the lens carrier 4 w...

Problems solved by technology

[0003] However, since one or more magnets 3 are needed to provide a magnetic field in actual use, and the magnets 3 will take up more space, the volume of the camera module motor is generally larger, which makes the application of the camera module motor The size of the camera module is relatively large
