Abstract
Official abstract text for this publication.
A lens driving device, includes a shell providing an accommodating space, a supporting frame accommodated in the accommodating space, a lens module received in the supporting frame and comprising at least one lens and a lens holder for holding the at least one lens, a circuit board accommodated in the accommodating space and having at least two adjacent surfaces, each of the at least two adjacent surfaces having a position sensor and an anti-shake coil arranged thereon and apart from each other, a magnet assembly having at least two first magnets and at least two second magnets fixed to the supporting frame, each of the at least two second magnets abutting against a corresponding first magnet and be adjacent to a corresponding position sensor. Comparing to the relevant technologies, the lens driving device has good performance and high reliability.
First claim
Opening claim text (preview).
What is claimed is: 1. A lens driving device, comprising: a shell providing an accommodating space; a supporting frame accommodated in the accommodating space; a lens module received in the supporting frame and comprising at least one lens and a lens holder for holding the at least one lens; a circuit board accommodated in the accommodating space and comprising at least two adjacent surfaces, each of the at least two adjacent surfaces comprising a position sensor and an anti-shake coil arranged thereon and apart from each other; a magnet assembly comprising at least two first magnets and at least two second magnets fixed to the supporting frame, each of the at least two second magnets abutting against a corresponding first magnet and be adjacent to a corresponding position sensor. 2. The lens driving device of claim 1 , wherein each first magnet comprises a first magnetized part and a second magnetized part in a same surface but with different magnetized directions. 3. The lens driving device of claim 2 , wherein an area of the first magnetized part is at least four times as that of the second magnetized part. 4. The lens driving device of claim 2 , wherein each second magnet is a single surface magnetized component abutting against the first magnetized part of the first magnet, and has a magnetized direction opposite to that of the first magnetized part. 5. The lens driving device of claim 4 , wherein a central line of the position sensor is located at a boundary between the first magnetized part and the second magnet. 6. The lens driving device of claim 5 , wherein a central line of the anti-shake coil is located at a boundary between the first magnetized part and the second magnetized part of the first magnet.
