Camera module motor, camera module and electronic device

Abstract

The invention discloses a camera module motor, a camera module and an electronic device, wherein the camera module motor comprises a housing, an upper elastic sheet, a lens carrier, a coil, a lower elastic sheet and a pedestal; the housing and the pedestal are embedded to form a hollow holding cavity; the upper elastic sheet, the lens carrier and the lower elastic sheet are positioned in the holding cavity; a lens is held in the lens carrier; the coil is wound on the surface of a lens shell, and is positioned between the lens shell and a dustproof retaining wall of the housing; and the dustproof retaining wall of the housing has magnetism and can provide a magnetic field required by the movement for the coil, thereby realizing a focusing function of the camera module; and thus, a magnet does not need to be arranged in the holding cavity individually, and the problem of relatively large size of the camera module motor due to relatively large space occupation of the magnet is solved. And meanwhile, the coil is wound on the surface of the lens shell and is positioned between the lens shell and the dustproof retaining wall of the housing, so the size of the camera module motor is further reduced.

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 and 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 wr...

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
