Voice coil motor base, voice coil motor and camera module

Abstract

The invention discloses a voice coil motor base, a voice coil motor and a camera module, and relates to the technical field of electronic equipment. The voice coil motor base comprises a metal plate,an optical filter and a plastic base, wherein a through hole is formed in the metal plate; The optical filter is fixed on the metal plate and shields the through hole, and the metal plate and the optical filter form an assembly; And the plastic seat is formed by injection molding of the edge position of the assembly. According to the voice coil motor base, the optical filter is embedded in the plastic base in an injection molding mode, the optical filter does not need to be positioned when the camera module is assembled, the positioning and assembling cost of the optical filter can be saved, and the influence on the quality of the camera module due to poor positioning of the optical filter is avoided; A supporting seat can be omitted, so that the height and the manufacturing cost of the camera module can be reduced; The metal plate increases the strength of the voice coil motor base, and the thickness of the plastic base can be properly reduced, thereby reducing the height of the camera module, and making up the problem of insufficient strength caused by the reduction of the plastic base.

Description

Technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a voice coil motor base, a voice coil motor and a camera module. Background technique [0002] The camera module is an important part of electronic devices with camera functions such as mobile phones and tablet computers. The camera module generally includes a printed circuit board (PCB), an image sensor, a support base, a voice coil motor, and a lens. The image sensor and the support base are both set on the PCB board, the voice coil motor is set on the support base, the voice coil motor and the support base are both provided with through holes, the lens is connected to the voice coil motor, and the through hole is directly opposite to the image sensor Set up. [0003] In the existing camera module, a filter for blocking the through hole is adhered to the support base. When attaching the filter, it is necessary to use a special fixture to position the support base to en...
