Description
Technical field
The present invention relates to a kind of photography module, particularly relate to a kind of automatically controlled driving element and adopt voice coil motor (Voice Coil Motor, VCM) the photography module of framework with automatically controlled driving element.
Background technology
Many electronic installations have the demand that an actuator is set, for example have vibration function mobile phone, have the magnetic magnetic head of perpendicular displacement actuator and the module camera etc. of focusing automatically; Wherein the actuator of widespread is that (Voice Coil Motor, VCM), reason is that voice coil motor can be reached accurate displacement to voice coil motor, and cheap, is suitable as the short distance micro-actuator of electronic installation.
See also Fig. 1, show the front-view schematic diagram of an existing photography module 7.Existing photography module 7 comprises: a camera lens 8; One automatically controlled driving element 9 is mounted on camera lens 8 mutually; One flexible member 10 is mounted on automatically controlled driving element 9 mutually; One insulating trip 11 is located on the flexible member 10; Pair of power source terminals 12 is welded in flexible member 10; And a Photosensing Units 13, be located at the below of automatically controlled driving element 9.Automatically controlled driving element 9 has a fixture 91; One movable piece 92 is located on the fixture 91; And an electric unit 93, be located at the outside of movable piece 92.Fig. 2 shows the vertical view of aforementioned existing flexible member 10, and it has a fixed part 101; One flexible portion 102 is connected and fixed portion 101; And a movable part 103, connect flexible portion 102.Please continue to consult Fig. 1, flexible member 10 and insulating trip 11 are in regular turn between the fixture 91 and movable piece 92 of automatically controlled driving element 9.Insulating trip 11 isolated flexible members 10 and other metalwork mutual conduction, and provide a structural strength to press attached flexible member 10, make flexible member 10 can be fixed in the appropriate location.
The fixed part 101 of flexible member 10 is organized mutually with the fixture 91 of automatically controlled driving element 9 and is established, the movable part 103 of flexible member 10 is organized mutually with the movable piece 92 of automatically controlled driving element 9 and is established, electric unit 93 mutual conduction of flexible member 10 and automatically controlled driving element 9, so as to transmitting power supply, aforementioned power source terminal 12 is welded to each other with flexible member 10.Photosensing Units 13 is located at the imaging end of photography module 7 and is organized mutually with the fixture 91 of automatically controlled driving element 9 and to establish.Aforementioned power source terminal 12 external external power source (not shown), when power supply in regular turn and when arriving the electric unit 93 of automatically controlled driving element 9 via power supply terminal 12, flexible member 10, the movable piece 92 of automatically controlled driving element 9 produces an axial displacement to be changed, camera lens 8 is moved along the optical axis straight line, and the movable piece 92 of automatically controlled driving element 9 drives the movable part 103 of flexible member 10, and makes flexible portion 102 produce linear displacement variation.
See also Fig. 3, show the vertical view of another existing flexible member 14, it is one-body molded with pair of power source terminals 144 and flexible member 14, to reduce the step that power supply terminal 144 is welded in flexible member 14.Flexible member 14 has fixed part 141, flexible portion 142, movable part 143 and power supply terminal 144.
Above-mentioned existing flexible member 10,14 is all the leaf spring of tool one uniform thickness.In the process of product microminiaturization now, more and more little for flexible member 10,14 desired K values, so the thickness of flexible member 10,14 is also more and more thin.Because it is little that the K value of flexible member heals, and can cause its rigidity littler (or rigidity deficiency), and this can cause also flexible member to be easy to generate fracture; Therefore, seem especially important of the balance between K value and the rigidity.Especially in the product design that power supply terminal and flexible member mutually combine, wish that flexible member can have very little K value, yet this can make that the rigidity of power supply terminal is obviously not enough.Have, power supply terminal needs to be bent in the process of assembling again, and power supply terminal regular meeting consequently produces useless part and cost is improved because of the not enough fracture easily of rigidity.In addition, make also attenuation of power supply terminal 144 under the more and more thin situation of the thickness of flexible member 14, and cause power supply terminal 144 and the electric loose contact of external power source.
Therefore, how effectively to reduce flexible member thickness and to make power supply terminal fracture be difficult for take place and cause electric loose contact and reduce manufacturing cost be the present problem demanding prompt solution of industry.
