Description
Technical field
The invention relates to a kind of camera module, particularly adopt voice coil motor (Voice Coil Motor, VCM) camera module of framework about a kind of electric control focusing element with electric control focusing element.
Background technology
Many electronic installations have the demand that an actuator is set, and for example have the mobile phone of vibration function, the magnetic magnetic head with perpendicular displacement actuator and automatic Focusing module camera etc.; Wherein the actuator of widespread is that (Voice Coil Motor, VCM), reason is that (Voice Coil Motor VCM) can reach accurate displacement to voice coil motor, and price is cheap, is suitable as the short distance micro-actuator of electronic installation to voice coil motor.
The short distance micro-actuator can be applicable to camera module as the electric control focusing element, with the purposes as automatic focusing.Please refer to Fig. 1, is known cross section structure synoptic diagram with camera module 1 of electric control focusing element.Mainly (Voice Coil Motor VCM) forms said camera module 1 by one year seat 40, a lens bearing seat 12, a camera lens 10 and a voice coil motor.Seat 40 had an accommodation space in said year, and the confession group is established said lens bearing seat 12.Be equipped with the camera lens 10 formed by a plurality of eyeglass (not shown) in the said lens bearing seat 12, and said camera lens 10 is to be screwed with said lens bearing seat 12, and is mounted in the said lens bearing seat 12.Magnetite 20, yoke 22 (Yoke) and coil 24 constitute aforementioned voice coil motors and are mounted on the accommodation space between said lens bearing seat 12 and the said year seat 40.Said camera module 1 is provided with a flexible member unit, so that preferable velocity of displacement of said voice coil motor and answer speed to be provided.Said flexible member unit includes flexible member 32 and reaches flexible member 34 down; The wherein said flexible member 32 of going up is arranged at said lens bearing seat 12 tops, and said flexible member 34 down is arranged at said lens bearing seat 12 bottoms.
Fig. 2 is that the aforementioned flexible member 32 of going up reaches a kind of known structure top view of flexible member 34 down.The flexible member 200 of Fig. 2 is to be tabular, and it has an outer edge area 210, inner edge zone 220 and a plurality of elasticity arm of force 230, and an end of each said elasticity arm of force is connected in said outer edge area 210 and the other end is connected in said inner edge zone 220.The part outer edge area 210 of said flexible member 200 is fixedly arranged on said year seat 40, and it partly is fixedly arranged on said lens bearing seat 12 in inner edge zone 220.When coil 24 feeds a predetermined polarity electric current, generation one electromagnetic force forward.The magnetic force direction of said magnetite 20 is same as said electromagnetic force; And the magnetic action power of generation addition; And said coil 24 is to organize mutually with said lens bearing seat 12 and said flexible member 34 down to establish; And then drive said lens bearing seat 12 through the promotion that said coil 24 receives magnetic force own and move to a precalculated position along optical axis direction, to carry out automatically controlled focus function.Said yoke 22 is in order to seal the magnetic line of force of said coil 24 and magnetite 20.After coil 24 fed the opposite polarity electric current, the electromagnetic force that said coil 24 produces disappeared with the magnetic force of said magnetite 20 mutually, and through the restoring force of said flexible member unit said lens bearing seat 12 is pushed back to the origin-location.
Since said go up flexible member 32 and down the outer edge area of flexible member 34 be fixedly arranged on said year seat 40; And the inner edge zone is fixedly arranged on said lens bearing seat 12; When said lens bearing seat 12 when optical axis moves with respect to said year seat 40 forward or backwards, the elasticity arm of force between aforementioned outer edge area and inner edge zone will have cumulative stress because receiving tensile deformation.Yet, also be the equal arc of a plurality of shapes and join because the elasticity arm of force 230 bending shapes of known elasticity element 200 shown in Figure 2 are continuous a plurality of arcs.When said flexible member 200 receives 10 rotations of said camera lens, inserts torsion that said lens bearing seat 12 produces, said camera lens 10 plane axial dipole fields and the pulling force that produces and said camera lens 10 generation inclination angles change the stress that produces and deform because of said these elasticity arm of forces of said lens bearing seat 12 forward and backward mobile stretchings; Because each elasticity arm of force arc bending shape equates; Can't see through each arc bending and absorb above-mentioned cumulative stress; Cause all stress all to concentrate at last on the contact in said these elasticity arm of forces and aforementioned outer edge area and inner edge zone; Make aforementioned inner edge zone and outer edge area all bear excessive internal vertical stress; Of a specified duration being prone to causes said flexible member 200 contact places tired, and makes the impairment in serviceable life of said flexible member 200.
