Diameter D4.That is, the main-body electrode 1 is oppositely arranged biconial structure using upper and lower, wherein pyramidal structure can be in optical axis
Corresponding additional-energy is generated when shifting, the size of the energy is proportional to drop and leaves the flat of pyramidal structure axle center distance
Side, while depending on the interfacial tension between oil-based liquid and conducting liquid, cone angle A and B (referring to Fig. 3) and conducting liquid
Contact angle in insulating hydrophobic film layer.Therefore, from thermodynamic system angle analysis, when drop axis deviation under external force
When pyramidal structure axle center, which is the increased process of free energy of whole system, so that entire lens system be made to be in one kind
Unstable state, and it is the process that a free energy reduces that drop, which returns to pyramidal structure axle center, so being spontaneous process, thus will
Optical axis draws go back to center.In the present invention, the biconial design of the main-body electrode 1 can be simultaneously effective stable or fixed
The center of conducting liquid and oil-based liquid, even if the axle center of two liquid surfaces, which shifts, also can during voltage changes
Automatically restore to former shaft core position.
As an example, the cone angle A in the first truncated cone-shaped space is equal to the cone angle B in the second truncated cone-shaped space, the first truncation
The height H1 of cone space is equal to the height H2 in the second truncated cone-shaped space.It in other embodiments, can also be according to lens parameter

A kind of protectiveness high molecular material of discipline the mid-1960s U.S. combinating carbide company exploitation, uses vacuum vapor deposition technique
Protective film is formed, film has thickness uniform, densification pin-free, transparent unstressed, excellent electrical insulating property and protective etc. special
Point.According to the difference of molecular structure, Parylene can be divided into the multiple types such as c-type, D type, N-type, F type, HT type, the present embodiment
In, the insulating hydrophobic film layer can be Parylene C, Parylene F, Parylene HT and Parylene N, wherein
Parylene HT effect is best, but higher cost.The hydrophobic layer plated film can also use fluoro-containing macromolecule material, such as
Teflon and Cytop, wherein Teflon and Cytop is trade name, is well known materials.Wherein, Parylene series usually may be used
To be plated by CVD；Teflon and Cytop can carry out plated film by spin coating or dip coating form.In the present embodiment, institute
The thickness range for stating insulating hydrophobic film layer can be at 100nm-50 μm, and it is inclined that thicker insulating hydrophobic film layer will lead to driving voltage
Height will lead to hydrone or salt ion penetrate plated film but if insulating hydrophobic film layer is excessively thin, cause to puncture in advance and lead to electricity
Phenomenon is solved, the damage of lens is caused.
As an example, the top electrode 3 and the lower electrode 2 are symmetrical above and below, and the top electrode 3 includes that the first cambered surface is curved
Tune 301, the lower electrode 2 include the second cambered surface bending section 201, can effectively be unloaded by electrode cambered surface curved design symmetrical above and below
It carries the liquid because caused by caused by temperature or in assembling process and solid volume changes.In the present embodiment, first cambered surface
Bending section 301 and the second cambered surface bending section 201 include S type section, and S type section has simultaneously to be bent up tune and be bent downwardly
Section, it is more adaptable, it can be avoided lens liquid and electrode thermal expansion and cold contraction effect because of caused by temperature change, guarantee lens hair
Raw axial symmetry deformation makes lens axle center not deflect.
As an example, the lower cover plate 4 is using adhesive means fixing seal in lower 2 surface of electrode, the oiliness liquid
Body 6 is then directly contacted with the lower electrode 2.Similar, the upper cover plate 5 is also fixed on the top electrode 3 using adhesive means
The sealing conducting liquid 7 is played the role of on surface.
Specifically, the top electrode 3 is connected with the conducting liquid 7, for regulating and controlling the conducting liquid 7 in insulating hydrophobic
Distribution of charges on film layer contact surface changes the oil-based liquid 6 and the conducting liquid 7 to reach by changing voltage
Two liquid surface curvature and then the effect for changing liquid lens diopter.
As an example, the oil-based liquid 6 can be silicone oil or the mixing of alkanes alcohol or several oil-based liquids is molten
Liquid.The conducting liquid 7 is the aqueous solution of at least one salt, such as KCl, NaCl, Na2SO4Deng, by regulate and control salt concentration can
To realize the oil-based liquid 6 and the conducting liquid 7 density having the same, to eliminate gravity to the shadow of liquid lens
It rings.
Specifically, the barrier liner 8 predominantly prevents from contacting and making between the top electrode 3 and the main-body electrode 1
At liquid lens short circuit, the sealing clamping ring 10 plays sealing function.The barrier liner 8 can be fluoro containing polymers, such as
Fluorinated ethylene propylene copolymer (FET) or polytetrafluoroethylene (PTFE) (PTFE).The shell 9 can be metal material or plastics,
It can process to obtain by numerically-controlled machine tool, can also be made by injection molding punch die.
Zooming liquid lens of the invention abandoned by mechanical means change the distance between multiple groups solid lens piece come
Realize zoom purpose, can directly by apply voltage come zoom, lens group can be made more to minimize, zoom rate faster,
Service life is long and more cheap.There are two taper structure designs for liquid lens tool of the invention, can be preferably and at the same time solid
Determine the conducting solution and oil-based liquid in liquid lens, promotes the globular interface between conducting solution and oil-based liquid in lens
The shaft core position of annular outer cover, though the hesitation due to caused by the rustic or liquid viscosity of liquid lens and cause
Non- axle center symmetric deformation occurs for liquid surface, which can also automatically restore to center.The present invention passes through following table on lens
The design of face symmetrical structure, liquid lens upper/lower electrode are designed to body caused by winding arc structure can be unloaded effectively because of temperature
Product variation and the lens deformation due to caused by various mechanical pressures in an assembling process.Structure design can make liquid saturating
