Abstract

The invention relates to a double-camera module group, and the module group comprises a circuit board, a lens seat, two image sensors, two lens module groups, a liquid crystal lens, and a welding pin. The two lens module groups are disposed on the same lens seat, and the bottom surface of the lens seat is connected with the circuit board. Moreover, the top surface of the lens seat is provided with the liquid crystal lens, thereby enabling the liquid crystal lens to cover the two lens module groups. The welding pin in the lens seat can enable the liquid crystal lens to be electrically connected with the circuit board. During assembly, the focuses of the lens module groups are adjusted, and the liquid crystal lens is used for focusing during photographing. In other words, the circuit board supplies power to the liquid crystal lens through the welding pin. The path of light passing through the liquid crystal lens is correspondingly changed during different voltages, and the focusing function is achieved under the condition of no voice coil motor. Therefore, the module group can effectively prevent the magnetic interference between two voice coil motors, and improves the image quality. Moreover, the two lens module groups achieve the focusing function through the liquid crystal lens, so the module group can effectively solve a problem that the movement of the two lens module groups is not consistent, and improves the image quality.
