Lens module
The present disclosure provides a lens module. The lens module includes a lens and a bearing seat matching connected to the lens; the lens includes a lens barrel, the lens barrel includes a first barrel provided with an optical aperture and a second barrel wall bending and extending from the first barrel wall; the bearing seat includes a surrounding wall around the second barrel wall; the lens is assembled on the bearing seat, the lens and the surrounding wall form an adhesive accommodating slot. The second barrel wall and the surrounding wall are bonded via the adhesive accommodating slot. Compared with related technologies, the lens module of the present disclosure occupies a smaller space, increases a screen-to-body ratio of an electronic product, and has low production difficulty.
