Abstract
A dustproof structure of a mobile phone camera module comprises a lens cone and a lens seat combined with the lens cone, wherein a lens is arranged in the middle of the upper end of the lens cone; external threads are arranged on the lateral wall; internal threads which are engaged with the external threads of the lens cone are arranged correspondingly on the lateral wall of the lens seat; moreover, a first dust board and a second dust board are arranged inwards on the lateral wall of the lens seat. Based on the original structure of one-layer dust board, a double-layer dust board smudginess-prevention structure is designed for the dustproof structure of the mobile phone camera module, small particles generated by the friction between threads can be completely sealed by the double-layer dust board, and even if extremely small dust particles pass through the tiny wall slot gap and reach the CCD surface, the dust particles can be neglected, for the size of the dust particles is less than that of the imaging specification. In addition, the turn of the thread engagement of the lens cone and the lens seat is reduced so as to reduce the chance of generating the small particles caused by the friction between the threads, thereby effectively solving the polluted problem of an image.
