The centers of the first and second dielectric elastomer films are filled with an aqueous solution so that the centers of the first and second dielectric elastomer films protrude outward, respectively, forming a hyperboloid protrusion. The outer peripheral surfaces of the first dielectric elastomer film and the second dielectric elastomer film, excluding the hyperboloid convex portion, are each coated with a carbon-resin electrode.
The electric-hydraulic hybrid driving hyperboloid lens of the embodiment uses the dielectric elastomer film to wrap the liquid medium to form the hyperboloid convex part to form the variable-focus imaging main body, and the carbon resin electrode coated on the periphery of the hyperboloid convex part drives the lens to deform and change the curvature radius of the lens after being electrified, so that self-zooming clear imaging is realized. The lens and the driver are designed in a separated mode, so that the manufacturing process is simplified, and the light transmittance and the imaging efficiency of the lens are improved.
An embodiment of the present invention provides a method for designing an electro-hydraulic hybrid driven hyperboloid lens, as shown in fig. 1, including the following steps:
step 110, establishing an imaging model of the electro-hydraulic hybrid driving hyperboloid lens;
and 120, determining the manufacturing parameters of the electro-hydraulic hybrid driving hyperboloid lens according to the required imaging range and the imaging model.
According to the design method of the embodiment, the imaging effect of the lens can be predicted in the design stage by establishing the imaging model of the electro-hydraulic hybrid driving hyperboloid lens, and optimization of structural parameters of the lens is facilitated; meanwhile, the manufacturing parameters meeting the imaging requirements can be accurately and quickly designed through the established model, and the lens is manufactured. In a word, the method is beneficial to the flexible optimization design of the electro-hydraulic hybrid driving hyperboloid lens, improves the manufacturing efficiency and saves the manufacturing cost. Further, theoretical reference is provided for expanding the application of the lens.
In the method of the above embodiment, step 110 specifically includes:
step 1101, establishing an energy-strain-driving electric field intensity relation model of the electro-hydraulic hybrid driving hyperboloid lens, which is as follows:
wherein W represents free energy of strain generation, s1Representing the circumferential stress, s, to which the lens membrane is subjected2Representing the radial stress, s, to which the lens membrane is subjected3Denotes the thickness direction stress, lambda, to which the lens film is subjected1Denotes the circumferential stretching ratio, λ, of the lens film2Denotes the radial elongation, λ, of the lens film3Represents the thickness-direction stretching ratio of the lens film,
which represents the strength of the driving electric field,
represents the nominal potential shift;
step 1102, establishing a geometric model of the electro-hydraulic hybrid driving hyperboloid lens, which is as follows:
in the formula, R represents a curvature radius, V represents a solution volume of the electro-hydraulic hybrid driven hyperboloid lens, and h represents a distance between the top of the electro-hydraulic hybrid driven hyperboloid lens and a middle projection plane of the electro-hydraulic hybrid driven hyperboloid lens;
step 1103, establishing a focal length-curvature radius relation model of the electro-hydraulic hybrid driving hyperboloid lens.
Specifically, the focal length of the lens can be calculated using the thick lens equation:
in the formula, R1And R2Represents the curvature radius of two curved surfaces of the lens, n represents the refractive index of the lens, and d represents the thickness of the lens;
simplifying the above formula to obtain a focal length-curvature radius relation model of the electro-hydraulic hybrid driving hyperboloid lens, which is as follows:
in the formula, f represents a focal length, R represents a curvature radius, n represents a refractive index of the electro-hydraulic hybrid driven hyperboloid lens, and h represents a distance between the top of the electro-hydraulic hybrid driven hyperboloid lens and a middle projection plane of the electro-hydraulic hybrid driven hyperboloid lens;
and 1104, combining the energy-strain-driving electric field intensity relation model, the geometric model and the focal length-curvature radius relation model of the electro-hydraulic hybrid driving hyperboloid lens, taking the strain of the dielectric elastomer film as a link, and connecting the geometric model with system energy to obtain an imaging model of the electro-hydraulic hybrid driving hyperboloid lens. When the imaging model is used, the driving voltage is used as an independent variable, the strain in the thickness direction of the lens can be obtained according to the energy-strain-driving electric field intensity relation model, the curvature change of the lens is obtained according to the geometric model, and the focal length change is further obtained according to the focal length-curvature radius relation model.
According to the structural characteristics and the action mechanism of the electro-hydraulic hybrid driving hyperboloid lens, the energy strain relation of the lens is established, factors influencing the energy strain relation are determined, and an imaging model of the electro-hydraulic hybrid driving hyperboloid lens, namely the relation between the driving electric field intensity and the focal length, is obtained. The imaging model established by the embodiment of the invention accurately describes the imaging mechanism of the electro-hydraulic hybrid driving hyperboloid lens, and the lens manufactured according to the imaging model has higher matching degree with the imaging requirement.
When the prestretching multiple of the lens film, the original diameter of the hyperboloid convex part and the volume of the solution in the hyperboloid convex part are determined, the lens is manufactured. Then, a 2.6kV driving voltage was applied to measure the diameter of the center before and after the lens deformation. The same pre-stretching multiple of the lens film, the original diameter of the hyperboloid convex part, the volume of the solution in the hyperboloid convex part and the driving voltage are selected, and then the diameters of the lens before and after deformation are calculated by using an imaging model. The measurements and calculations were compared by three examples and the results are given in the following table:
| lens diameter/mm | Lens volume/cm3 | Pre-stretching multiple | Measured value/mm | Calculated value/mm |
| 31.5 | 5 | 4 | 29.4 | 29.0 |
| 32.6 | 5 | 3 | 32.2 | 32.2 |
| 14.7 | 0.5 | 4 | 13.8 | 13.6 |
As can be seen from the above table, the theoretical calculation value is basically consistent with the data of the experimental measurement value, which proves that the imaging model established in the embodiment accurately describes the imaging mechanism of the electro-hydraulic hybrid driving hyperboloid lens, and the lens manufactured according to the imaging model has a high matching degree with the imaging requirements.
The design method of the embodiment of the invention determines the parameter relation and the deformation characteristic in the lens structure by establishing the imaging model of the electro-hydraulic hybrid driving hyperboloid lens; after the voltage is applied, the driver around the lens presses the convex lens in the center thereof, and imaging in the case of zooming is realized. And selecting proper lens volume and lens driver parameters according to the required lens imaging range. When the volume of the lens is small, the solution is not filled too much, otherwise the initial curvature is large, and the focal length change after driving is small. The difference of the curvatures of the two films of the lens is small, otherwise, the normal imaging cannot be realized. When packaging, a pure and transparent solution is selected so as not to influence the transparency of the lens. When the efficiency of the lens actuator needs to be improved, the pre-stretching of the lens film can be increased, the volume of the solution of the lens can be reduced, the curvature radius of the lens film can be reduced, and the like.
The embodiment also provides a manufacturing method of the electro-hydraulic hybrid driving hyperboloid lens, which includes the following steps:
step 210, fixing the edge of the pre-stretched first dielectric elastomer film on an annular supporting frame, and enabling the center of the first dielectric elastomer film to protrude downwards to form a recess;
step 220, slowly dripping the solution into the recess until the liquid level of the solution in the recess is flush with the edge of the recess;
step 230 of attaching the stretched second dielectric elastomer film to the upper surface of the first dielectric elastomer film, the centers of the first dielectric elastomer film and the second dielectric elastomer film being filled with a solution to form a hyperboloid protrusion;
step 240, uniformly coating carbon grease on the outer surfaces of the first dielectric elastomer film and the second dielectric elastomer film except for the hyperboloid convex part.
The manufacturing method of the embodiment enriches the manufacturing process of the electric-hydraulic hybrid driving hyperboloid lens by using the negative pressure method, and saves the manufacturing cost at the same time.
Preferably, in step 210, a depression is formed by protruding the center of the first dielectric elastomer film downward through the negative pressure bladder opening. The operation flow is simplified, and the manufacturing cost is reduced.
Preferably, in step 230, when the second dielectric elastomer film is bonded to the upper surface of the first dielectric elastomer film, the center of the second elastomer film is bonded to the center of the first dielectric elastomer film, the recess filled with the solution is sealed, and after no bubble is generated, the remaining portion of the second elastomer film is bonded to the first elastomer film along the periphery of the recess.
