Abstract

An anti-shake lens driving apparatus is provided, including a lens carrier, for carrying at least a lens set; a magnet module, disposed on the outer surroundings of the lens carrier for pushing the lens carrier; a suspension part, further including an upper suspension resilient element and a lower suspension resilient element, the upper and lower suspension resilient elements respectively including a fixed part, a movable part and at least a suspension element; the at least a suspension element connecting the fixed part and the movable part; the fixed part being fixed to an upper cover and a base; the movable part being fixed to the upper and lower part of the lens carrier respectively; and the upper cover and the base being disposed respectively at the upper and lower part of the magnet module and the suspension part for providing protection.

Claims

1. An anti-shake lens driving apparatus, comprising:

a lens carrier, for carrying at least a lens set;

a magnet module, disposed on the outer surroundings of said lens carrier for pushing said lens carrier;

a suspension part, further including an upper suspension resilient element and a lower suspension resilient element, said upper and said lower suspension resilient elements respectively including a fixed part, a movable part and at least a suspension element;

said at least a suspension element connecting said fixed part and said movable part;

said fixed part being fixed to an upper cover and a base;

said movable part being fixed to a upper and lower part of said lens carrier respectively; and

said upper cover and said base being disposed respectively at the upper and lower part of said magnet module and said suspension part for providing protection.

2. The anti-shake lens driving apparatus as claimed in claim 1, wherein said at least a suspension element extends from said fixed part at an angle to said movable part.

3. The anti-shake lens driving apparatus as claimed in claim 1, wherein said at least a suspension element is a U-shape buffer element.

4. The anti-shake lens driving apparatus as claimed in claim 1, wherein said upper suspension resilient element and said lower suspension resilient element are formed monolithically.

5. The anti-shake lens driving apparatus as claimed in claim 1, wherein said magnet module further comprises a coil set, a magnet set and an outer yoke, disposed in the order from said lens carrier 1 outwards;

and when a current runs through the coil set, said lens carrier moves linearly along the axis of said lens carrier.

6. The anti-shake lens driving apparatus as claimed in claim 1, wherein said outer yoke is formed monolithically.

7. The anti-shake lens driving apparatus as claimed in claim 1, wherein each of the four corners of said outer yoke is disposed with an inner yoke.

8. The anti-shake lens driving apparatus as claimed in claim 2, wherein rigidity of the upper and lower suspension resilient elements can be adjusted by the cord width of said at least a suspension element to achieve the compensation of the tile angle.
