Mounting base, voice coil motor and camera device

Abstract

This invention discloses a mounting base, a voice coil motor, and a camera device. The mounting base has a plurality of outer side walls and a central area hollowed out to form a receiving space. Each outer side wall includes a first outer side wall with a plurality of first adhesive grooves spaced apart along a first direction. Each first adhesive groove includes a first groove body arranged along the first direction and at least one second groove body arranged along a second direction, with the second groove body communicating with the first groove body. Therefore, by providing the first adhesive grooves, the mounting base can prevent adhesive overflow into the receiving space while increasing the surface area available for bonding, thus helping to avoid product defects.
