Alternatively, the electro-active driving member 7 may be an ion exchange polymeric metal member comprising a first electrode, a second electrode and an ion exchange layer, wherein the ion exchange layer is located between the first electrode and the second electrode. Of course, the electro-active driving element 7 may be a piezoelectric ceramic element or a shape memory alloy element.
Ion exchange polymeric metal (Ion-exchange Polymer Metal Composite, IPMC) pieces are briefly described below.
Here, as shown in fig. 2, when the ion exchange polymeric metal member is energized and there is a change in voltage or current, the ion exchange polymeric metal member is greatly deformed, and the greater the change in Δv or Δi, the greater the amount of deformation of the ion exchange polymeric metal member.
The two ends of the ion exchange polymeric metal piece are fixed on a target component, wherein the target component is one of the camera, the circuit board and the fixing plate. Namely, the target component and the two ends of the ion exchange polymerization metal piece are hard fixed and cannot generate relative displacement; the other parts except the two ends of the ion exchange polymeric metal piece are not connected with the target component, so that the ion exchange polymeric metal piece is fixed, and deformation of the ion exchange polymeric metal piece after being electrified can not be influenced.
As shown in fig. 1, optionally, the circuit board 4 includes a rigid portion 41, where the rigid portion 41 is located between the camera 1 and the fixing plate 5, and the rigid portion 41 has a first surface and a second surface opposite to each other, where the camera 1 is disposed on the first surface, and where the electro-active driving element 7 is disposed on the second surface.
On this basis, the support 6 is provided on the side of the fixing plate 5 facing the rigid portion 41, and is movably connected to the rigid portion 41.
Here, the supporting member 6 is located in the central region of the fixing plate 5, may be integrally formed with the fixing plate 5, or may be fixed to the fixing plate 5 by glue, and may be used as a pivot point. The shape of the support 6 may be a bar, a polygonal line, a hemispherical shape, or the like, and is specifically limited herein as long as the camera 1 can be supported and the camera 1 can be moved based on the support.
In order to enable the camera head 1 to move based on the support member 6, as an alternative implementation, as shown in fig. 1, the support member 6 is a hemispherical structure, and an arc-shaped protruding portion of the hemispherical structure is far away from the fixing plate 5 and is in contact with the rigid portion 41.
Here, since the fixing plate 5 and the circuit board 4 have a gap therebetween, the supporting member 6 is in contact with the circuit board 4, and heat generated when the camera 1 operates can be dissipated by convection of air through the supporting member 6, it is possible to reduce problems of imaging quality due to high temperature of the camera 1.
It should be noted that, as shown in fig. 1, the circuit board 4 further includes a flexible portion 42 (also referred to as a flexible circuit board) connected to the rigid portion 41, and the flexible portion 42 is located outside the camera 1.
Specifically, the electro-active driving element 7 is located between the fixing plate 5 and the circuit board 4, as shown in fig. 3, the camera 1 is inclined relative to the fixing plate 5, and the electro-active driving element 7 is electrified to deform the camera 1 so as to drive the whole camera 1 to rotate around the supporting element 6, and after the electro-active driving element 7 contacts with the fixing plate 5, when the deformation of the electro-active driving element 7 is increased, an interaction force is generated between the electro-active driving element 7 and the fixing plate 5, so that the camera 1 is driven to move, specifically, an angle equal to the inclination angle of the camera 1 is corrected in the opposite direction of the inclination direction of the camera 1, and finally, the anti-shake focusing of the camera module is realized. Specifically, the camera 1 may be driven to rotate in a direction approaching or separating from the fixed plate 5.
Optionally, the number of the ion exchange polymeric metal pieces is four, and the four ion exchange polymeric metal pieces are disposed on one side of the circuit board 4 facing away from the camera 1 and are distributed at intervals around the supporting piece 6.
Here, alternatively, both ends of the ion exchange polymeric metal member are fixed to the side of the circuit board 4 facing away from the camera head 1 by solder paste.
It should be noted that the four ion exchange polymeric metal pieces can be controlled by the second driving device of the electronic device to apply the power supply voltage or current variation, so that the power supply voltage or current variation is not affected before each other. The deformation of the camera is controlled by the power supply voltage or current, so that the camera 1 is driven to compensate the anti-shake angle.
Here, whether the camera 1 is tilted may be implemented by a detection device, and how this is specifically implemented, as an optional implementation manner, the camera module further includes:
the inclination angle detection mechanism is arranged on at least one of the camera 1, the circuit board 4 and the fixed plate 5, and is electrically connected with the circuit board 4.
Here, the tilt angle detection mechanism is used to detect the tilt angle of the camera 1. The inclination angle detection mechanism can be an angle sensor, a triaxial sensor, a gyroscope or other devices, or an assembly structure formed by a magnetic piece and a Hall sensor, and the like.
Alternatively, as shown in fig. 1 and 3, the inclination angle detection mechanism includes: a magnetic element 10, wherein the magnetic element 10 is arranged on the fixed plate 5; a TMR angle sensor 11 is fixed on a surface of the circuit board 4 away from the lens 2, and the TMR angle sensor 11 is used for sensing the position of the magnetic element 10, so as to determine a relative angle between the camera 1 and the fixed board 5, where the relative angle is understood as an angle of a magnetic induction line corresponding to a magnetic field generated by the magnetic element 10 at the position where the TMR angle sensor is located.
The magnetic element 10 is disposed on the fixed plate 5 at a position opposite to the TMR angle sensor 11, that is, the magnetic element 10 is vertically opposite to the TMR angle sensor 11, and functions to provide a magnetic field. Here, the angle of the magnetic induction line includes the angle size and direction of the magnetic induction line.
Here, the TMR angle sensor 11 is disposed in the magnetic field of the magnetic element 10, and is designed so that the purpose is to make the TMR angle sensor 11 sense the angle change of the magnetic induction line of the magnetic element 10 more accurately, thereby determining the tilt angle of the camera 1.
Here, the tilt angle of the camera 1 includes the tilt angle magnitude and the tilt direction of the camera 1.
In particular, the magnetic element 10 may be fixed to the fixed plate 5 by gluing. TMR angle sensor 11 may be fixed to the side of circuit board 4 remote from lens 2 by solder paste.
In an alternative implementation, the number of the magnetic elements 10 is four, and the four magnetic elements 10 are respectively located at four corner edges of the first area of the fixing plate 5.
Alternatively, the first area is a projection area of the photosensitive device 3 projected on the fixing plate 5.
Here, the magnetic element 10 may be a magnet.
Accordingly, the number of TMR angle sensors 11 is four, opposite to the position of the magnetic element 10.
The second driving means on the electronic device supplies power to TMR angle sensor 11. After the information of the magnetic induction angle change of the magnetic element 10 detected by the TMR angle sensor 11 is transmitted to the data processing system end of the second driving device for corresponding data processing, the jitter angle is compensated through the feedback mechanism of the second driving device and the electro-active driving element 7.
The anti-shake operation principle of the camera module according to the embodiment of the present application is briefly described below.
After the camera 1 shakes, the positions of the TMR angle sensor 11 and the magnetic element 10 are changed relatively, so that the TMR angle sensor 11 can detect the change of the magnetic induction line angle of the magnetic element 10; after the TMR angle sensor 11 outputs the detected information of the angle change of the magnetic induction line to the data processing system of the second driving device for processing, the magnitude of the energizing voltage or the energizing current given to the electro-active driving element 7 is adjusted through a feedback mechanism, so that the energizing voltage or the energizing current of the electro-active driving element 7 is changed, deformation amounts with different magnitudes are generated, the deformation amounts are contacted with the fixed plate 5, mutual thrust is generated, finally the camera 1 is driven to move, and the optical axis of the camera 1 with the angle offset due to shaking is restored to the initial position (namely the position perpendicular to the fixed plate 4), thereby realizing the anti-shake function.
The camera module comprises a camera, a circuit board, a fixing plate, a supporting piece and an electro-active driving piece, wherein the camera comprises a lens and photosensitive devices, and the photosensitive devices are distributed opposite to the lens; the circuit board is electrically connected with the photosensitive device; the fixed plate is arranged on one side of the camera, which is far away from the lens, and a gap is formed between the fixed plate and the camera; the supporting piece is arranged on one of the camera, the circuit board and the fixed plate, and the camera is movably connected with the fixed plate through the supporting piece; the electro-active driving piece is arranged in one of the camera, the circuit board and the fixed plate, is positioned in the gap and is distributed with the supporting piece in a dislocation way, and is electrically connected with the circuit board; under the condition that the electro-active driving piece is electrified and deformed, the electro-active driving piece drives the camera to move, so that the camera which is inclined can be adjusted through the deformable electro-active driving piece, thereby realizing the anti-shake of a larger angle and improving the imaging quality of the camera module.

Specifically, the method may include:
step 501, obtaining a first inclination angle of a camera;
here, the first inclination angle of the camera is acquired by the inclination angle detection mechanism of the electronic apparatus.
Step 502, determining a target power-on parameter of the electro-active driving piece according to the first inclination angle, wherein the target power-on parameter is a target voltage value or a target current value, and the inclination angle of the camera has a preset corresponding relation with the power-on parameter of the electro-active driving piece;
the different inclination angles of the camera correspond to different energization parameters of the electro-active driving element.
And step 503, controlling the electric driving part to be electrified with the target electrifying parameter so as to electrify and deform the electric driving part, and driving the camera to move until the optical axis of the camera is perpendicular to the fixed plate.
Specifically, the deformation amount of the electro-active driving piece is determined by the power-on parameters of the electro-active driving piece, that is, the electro-active driving piece is powered on by different power-on parameters, and the deformation amounts of the electro-active driving piece corresponding to the power-on deformation are different.
That is, the inclination angle of the camera has a first preset correspondence with the energization amount of the electro-active driving element, and the energization amount of the electro-active driving element has a second preset correspondence with the energization amount of the electro-active driving element.
Here, when the electro-active driving element is controlled to be electrified with the target electrified parameter to deform, the generated deformation amount can drive the camera 1 to move, so that the optical axis of the camera 1 with the angle offset due to shaking is perpendicular to the fixed plate.
