Abstract
A lens module includes a barrel defining a first through hole, two or more lenses received in the first through hole of the barrel including at least one movable lens, and at least one driving device moving the movable lens. The driving device includes a fixed portion, a movable portion, hydraulic fluid, and an adjustment pole. The fixed portion is secured on the inner surface of the barrel and defines a trough with an opening facing along the axis of the lens module. The movable portion has a first end and an opposite second end, the first end inserted into the trough and sealing the space between the first end and the bottom wall of the trough, and the second end secured to a movable lens. The hydraulic fluid fills the space. The adjustment pole is inserted into the trough from a second through hole running through the barrel and a wall of the trough adjacent to the barrel, and is movable in the second through hole.
