Abstract

A lens module comprises a lens barrel, a lens base, a battery of lens and colloid, wherein the lens barrel comprises an inner side wall and an outer side wall opposite to the inner side wall; the battery of lens is fixedly arranged in the inner side wall; the lens base is provided with a top and a bottom; at least a flange layer surrounding the outer side wall extends from the outer side wall of the lens barrel along the radial direction; at least three bumps are uniformly distributed on the flange layer; the inner side wall at the top of the lens base is a continuous smooth curve; and the lens barrel is stuck on the inner side wall at the top of the lens base by the bumps and is fixed in the inner side wall of the lens base by the colloid coated between the bumps and the inner side wall of the lens base. The invention also relates to a camera module applying the lens module.

Description

technical field [0001] The invention relates to a lens module, in particular to a lens module with a dustproof function and a camera module used therefor. Background technique [0002] With the development of multimedia technology, digital cameras, video cameras and mobile phones with camera functions are more and more favored by consumers, and people's imaging quality for such devices is also getting higher and higher. However, during the manufacturing process, there are often dust problems, which affect the quality and stability of the product's photographing. Therefore, reducing the pollution of dust to the camera module will help improve the photographing quality of the camera module. [0003] Existing camera modules generally include a lens module for imaging and an image sensor disposed in the lens module. The lens module includes a lens barrel used for accommodating lenses and a lens seat through which the lens barrel is threaded. Because the lens barrel and the len...
