Abstract

A driving module is provided. The driving module includes a sensor module, a holder and at least three positioning components. The holder corresponds to the sensor module and is for holding an optical element. The positioning components are disposed between the sensor module and the holder.

First claim

What is claimed is:

1 . A driving module, comprising:
a sensor module; a holder assembly corresponding to the sensor module; and at least three positioning components disposed between the sensor module and the holder assembly.

2 . The driving module as claimed in claim 1 , wherein the holder assembly is integrally formed with the position components as one piece.

3 . The driving module as claimed in claim 1 , wherein the sensor module comprises a base integrally formed with the position components as one piece.

4 . The driving module as claimed in claim 1 further comprising a filter disposed between the sensor module and the holder assembly.

5 . The driving module as claimed in claim 4 , wherein the positioning components abut the filter.

6 . The driving module as claimed in claim 1 , wherein the positioning components comprise metal material.

7 . The driving module as claimed in claim 1 , wherein the holder assembly comprises a recess disposed on a surface, of the holder assembly, facing to the sensor module.

8 . The driving module as claimed in claim 7 , wherein the holder assembly further comprises a plurality of recesses disposed on the surface.

9 . The driving module as claimed in claim 7 , wherein the positioning components comprise the same sidewall as the recess.

10 . The driving module as claimed in claim 8 , wherein the positioning components comprise the same sidewall as the recess.

11 . The driving module as claimed in claim 7 , wherein the holder assembly has a slightly rectangular shape, and the recess is at a corner of the holder assembly.

12 . The driving module as claimed in claim 8 , wherein the holder assembly has a slightly rectangular shape, and the recess is at a corner of the holder assembly.

13 . The driving module as claimed in claim 1 , wherein the holder assembly has a slightly rectangular shape, and the positioning components are at corners of the holder assembly.

14 . The driving module as claimed in claim 1 , wherein an optical axis of an optical element passes through a polygonal area formed by the positioning components.

15 . A driving module, comprising:
a sensor module; and a holder assembly, for holding an optical element, comprising a metal bottom abutting the sensor module.

16 . The driving module as claimed in claim 15 , wherein the metal bottom comprises a recess at a surface, of the metal bottom, facing the sensor module.
