Dual-lens module driving device

A dual-lens module driving device, characterized in comprising:

• a shell comprising a top wall and a side wall extending from the top wall, wherein the top wall is provided with a first opening and a second opening in parallel;
• a base forming an accommodating space matched with the shell;
• a support frame accommodated in the accommodating space and comprising a first accommodating cavity arranged corresponding to the first opening and a second accommodating cavity arranged corresponding to the second opening;
• a first lens tube and a second lens tube respectively accommodated in the first accommodating cavity and the second accommodating cavity;
• a first lens set and a second lens set respectively matched in the first lens tube and the second lens tube;
• a first focusing coil set annularly arranged on an outside surface of the first lens tube for driving the first lens tube AF focus or adjust the change of an optical axis during AF focus;
• a second focusing coil set annularly arranged on an outside surface of the second lens tube for driving the second lens tube AF focus or adjust the change of an optical axis during AF focus;
• a first magnetic steel set fixed in the support frame and arranged opposite to the first focusing coil set with spacing;
• a second magnetic steel set fixed in the support frame and arranged opposite to the second focusing coil set with spacing;
• a circuit board arranged below the first magnetic steel set and the second magnetic steel set, and fixed in the base;
• an optical anti-shaking coil set arranged below the first magnetic steel set and the second magnetic steel set, and fixed in the circuit board for driving the support frame to move in a horizontal direction;
• a first elastic sheet set with one end fixed in the support frame, and the other end fixed in the first lens tube;
• a second elastic sheet set with one end fixed in the support frame, and the other end fixed in the second lens tube;
• and
• a translational suspension system composed of a plurality of suspension wires, wherein the plurality of suspension wires are respectively arranged at circumferential sides of the support frame for supporting the first focusing coil set or the second focusing coil set to make small displacement in any direction in a vertical optical axis plane, and the suspension wires are fixed in the base.
