As shown in fig. 7, in a case that the four third regions are regions respectively parallel to four sides of the square structural member, the four electro-driving sheets include two first electro-driving sheets 31 and two second electro-driving sheets 32, the two first electro-driving sheets are disposed oppositely, and both the two first electro-driving sheets 31 are in a strip structure, two ends of the first electro-driving sheets 31 extend out of the region where the optical filter 2 is located, and a portion of the first electro-driving sheets 31 extending out of the region where the optical filter 2 is located is in line connection with the circuit board 6 to receive a voltage applied to the first electro-driving sheets 31 by the circuit board 6.
The second electro-active plate 32 may have a U-shaped configuration. The two second electro-driving sheets 32 are oppositely arranged, each second electro-driving sheet 32 includes a main body portion and an extension portion perpendicular to the main body portion, each main body portion is correspondingly arranged on one third area, the extension portions extend to the outside of the area where the optical filter 2 is located, and the extension portions are in line connection with the circuit board 6 to receive the voltage applied to the second electro-driving sheets 32 by the circuit board 6.
The voltages applied to the two first electro-active plates 31 may be the same or different, and the voltages applied to the two second electro-active plates 32 may be the same or different.
Further, the third region is located on the first surface of the optical filter 2, or the third region includes a first sub-region located on the first surface of the optical filter 2 and a second sub-region located on the second surface of the optical filter 2, and the first sub-region and the second sub-region are distributed in a reverse manner.
The third region is located on the first surface of the optical filter 2, or the optical filter 2 and the electric drive sheet are connected in a manner shown in fig. 8, that is, the optical filter 2 is embedded in the electric drive sheet, in this case, the third region includes a first sub-region located on the first surface of the optical filter 2 and a second sub-region located on the second surface of the optical filter 2, and the first sub-region and the second sub-region are distributed in a reverse manner.
Further, the electrodrive sheet is an ion conduction vibrating sheet, the ion conduction vibrating sheet comprises a first electrode layer, an ion exchange resin layer and a second electrode layer which are sequentially stacked, and a polymer electrolyte is arranged in the ion exchange resin layer.
Specifically, the electro-driven plate can be made of ion-exchange polymer metal composite (IPMC). The IPMC material is a novel electrically-actuated functional material, and is formed by using an ion-exchange resin layer (such as fluorocarbon polymer) as a substrate and plating a noble metal (such as platinum, silver, etc.) on the surface of the substrate to form electrode layers, i.e., a first electrode layer and a second electrode layer, as shown in fig. 11, where reference numerals a and B in fig. 11 are respectively the first electrode layer and the second electrode layer. The ion exchange resin layer C includes a polymer electrolyte containing cations and anions, and the positions and the numbers of the cations and the anions in fig. 11 are only schematic and do not represent an actual situation.
As shown in fig. 12 and 13, when a voltage is applied to the IPMC in the thickness direction, hydrated cations in the polymer electrolyte move to the cathode side, causing a difference in swelling of the anode and cathode surfaces of the IPMC, thereby causing deformation and bending toward the anode surface, so that the degree of bending of the IPMC can be controlled by controlling the energization voltage or current of the IPMC, so that the IPMC is displaced in the transverse direction.
The IPMC material is a novel driving material and has the advantages of light driving weight, large displacement, low driving voltage and the like. The advantage of adopting IPMC in the driving device is obvious, for example, IPMC is a non-magnetic material and can not generate magnetic interference; the displacement and velocity generated by IPMC deformation decrease in proportion to the thickness of IPMC, and the force generated by IPMC deformation increases in proportion to the cube of the thickness of IPMC. Therefore, the thickness of the IPMC can be set according to actual conditions to achieve the desired displacement, velocity and force generated by IPMC deformation.
Furthermore, the electrodrive sheet is an ion conduction vibrating sheet; when the voltage applied to the electro-driving sheet is a first voltage, the electro-driving sheet drives the optical filter 2 to bend along a first direction; when the voltage applied to the electro-driving sheet is a second voltage, the electro-driving sheet drives the optical filter 2 to bend along a second direction; wherein the first voltage and the second voltage are opposite in polarity, and the first direction is opposite to the second direction.
The ion-conduction driving plate driving filter 2 may be caused to bend in the first direction or the second direction by applying a voltage to the ion-conduction driving plate. The first direction may be a direction toward the circuit board 6, and the second direction may be a direction away from the circuit board 6; alternatively, the first direction may be a direction away from the circuit board 6, and the second direction may be a direction toward the circuit board 6.
Further, when the voltage applied to the electro-driving plate is a first voltage, the electro-driving plate drives the optical filter 2 to bend along a first direction by a first curvature; when the voltage applied to the electro-driving plate is a third voltage, the electro-driving plate drives the optical filter 2 to bend along the first direction by a second curvature; the first voltage and the third voltage have the same polarity, the third voltage is greater than the first voltage, and the first curvature is different from the second curvature.
The second curvature may be greater than the first curvature. When the curvature of the optical filter 2 is required to be larger, larger voltage can be applied to the ion conduction driving sheet; when a smaller curvature of the filter 2 bend is required, a smaller voltage may be applied to the ion-conducting driver plate. The voltage applied to the ion conduction driving sheet and the curvature of the optical filter 2 have a corresponding relation, and the corresponding relation can be burnt into the camera module. For example, the voltage value applied to the IPMC may be recorded according to the variation of the definition of the camera module, and the optimal voltage code value (i.e. code value) is burned into the camera module. The code value can be directly called in the using process of the terminal so as to improve the picture quality of the picture.
Further, when the voltage applied to the electro-driving plate is a first voltage, the electro-driving plate drives the filter 2 to bend along a first direction at a first rate; when the voltage applied to the electro-driving plate is a third voltage, the electro-driving plate drives the optical filter 2 to bend along the first direction at a second rate; the first voltage and the third voltage have the same polarity, the third voltage is greater than the first voltage, and the first rate is different from the second rate.
The second rate may be less than the first rate. When the filter 2 is required to move at a high speed, the filter 2 can be driven to move at a high speed by applying a high voltage to the ion conduction driving sheet; when a smaller rate of movement of the filter 2 is required, the filter 2 can be driven to move at a smaller rate by applying a smaller voltage to the ion-conducting driver plate. There is a correspondence between the magnitude of the voltage applied to the ion-conducting driver plate and the rate of movement of the filter 2, and in the case where the rate at which the filter 2 needs to be moved is determined, the magnitude of the voltage applied to the ion-conducting driver plate can be determined from this correspondence.
The embodiment of the application further provides electronic equipment which comprises the camera module in any one of the embodiments.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application.
