The electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Referring to fig. 1, a schematic diagram of a partial structure of an electronic device according to an embodiment of the present application is shown.
In an embodiment of the present application, an electronic device may specifically include: the anti-shake driving film comprises a base 10, an anti-shake driving film layer 20 and a camera module 30; the anti-shake driving film layer 20 is disposed on the base 10 and connected to the camera module 30, and the anti-shake driving film layer 20 extends or contracts on the base 10 to drive the camera module 30 to deflect relative to the base 10. In the embodiment of the application, since the anti-shake driving film layer 20 is arranged on the base 10 in the form of a film layer, the space occupied by the anti-shake driving film layer 20 is smaller, and the camera module 30 can be driven to deflect at a larger angle in a limited space along with the expansion or contraction of the anti-shake driving film layer 20 on the base 10, so that the jitter compensation is realized.
In the embodiment of the application, when the electronic device shoots an image or video by using the lens in the camera module 30, if the camera module 30 is detected to shake, the position of the lens in the camera module 30 can be changed relative to the base 10 by changing the relative position relationship between the camera module 30 and the base 10, so that the shake generated by the camera module 30 is counteracted, and the anti-shake of shooting is realized. As shown in fig. 1, the anti-shake driving film 20 can generate macroscopic driving force in the F direction for the camera module 30 through microscopic movement of expansion or contraction of the anti-shake driving film, so that the camera module 30 realizes shake compensation opposite to the F direction.
In the embodiment of the present application, the base 10 can play a role in supporting the anti-shake driving film layer 20 and the camera module 30. In an embodiment of the present application, the camera module 30 may specifically include: a lens bracket, and a lens and a circuit board which are arranged on the lens bracket; the lens is arranged opposite to the photosensitive chip on the circuit board; the anti-shake driving film layer 20 is connected to the lens support, and the anti-shake driving film layer 20 extends or contracts on the base 10, so as to drive the lens to deflect relative to the base 10 through the lens support.
It is understood that the circuit board of the camera module 30 includes, but is not limited to, a flexible circuit board.
In the embodiment of the present application, the anti-shake driving film layer 20 can not only receive an external control signal (for example, a deflection signal sent by an electronic device), but also control expansion or contraction of the anti-shake driving film layer according to the external control signal, so as to perform a function of deflection driving of the camera module 30. In an embodiment of the present application, the anti-shake driving film layer 20 may specifically include: the anti-shake driving blocks 21 are uniformly arranged along the circumferential direction of the camera module 30 and are respectively connected with the camera module 30, and the anti-shake driving blocks 21 extend or retract to drive the camera module 30 to deflect relative to the base 10; wherein the extending or contracting directions of at least two anti-shake driving blocks 21 are different.
In the embodiment of the present application, the anti-shake driving film layer 20 is formed by a plurality of anti-shake driving blocks 21, and the anti-shake driving blocks 21 can generate a deflection driving force for the camera module 30 along with respective expansion or contraction of the anti-shake driving blocks 21. When the extending or contracting directions of the at least two anti-shake driving blocks 21 are different, the at least two anti-shake driving blocks 21 generate a friction force in a certain direction to the camera module 30, and under the action of the friction force, the camera module 30 can deflect opposite to the friction force direction relative to the base 10 so as to realize shake compensation.
Referring to fig. 2, a schematic structural diagram of an anti-shake driving film layer according to an embodiment of the application is shown. As shown in fig. 2, a plurality of anti-shake driving blocks 21 may be respectively disposed on the base 10 in an X direction (lateral direction) and a Y direction (longitudinal direction), wherein the X direction is perpendicular to the Y direction, and the plurality of anti-shake driving blocks 21 form an anti-shake driving film layer 20. In the embodiment of the present application, the anti-shake driving block 21 may generate driving forces along the X direction and the Y direction, i.e. the driving force along the F direction in fig. 1, for the camera module 30.
It should be noted that, the anti-shake driving block 21 may be disposed along the circumferential direction of the camera module 30 in a plurality of manners, including but not limited to, as shown in fig. 2, wherein the included angle between the X direction and the Y direction may be any value within a range of 0 ° to 180 °. In the embodiment of the present application, the structure and principle of the anti-shake driving block 21 shown in fig. 2 are only explained by the arrangement thereof, and other references are only needed.
In the embodiment of the application, each anti-shake driving block 21 can independently receive an external control signal, and further control the expansion or contraction of the anti-shake driving block according to the external control signal, so as to play a role in driving the deflection of the camera module 30. Referring to fig. 3, a schematic cross-sectional structure of an anti-shake driving block according to an embodiment of the application is shown. As shown in fig. 3, the anti-shake driving block 21 may specifically include: a sensing layer 212 and a vibration layer 213 stacked; the sensing layer 212 is connected with the base 10, and the vibration layer 213 is connected with the camera module 30; the sensing layer 212 drives the vibration layer 213 to extend or retract, so that the vibration layer 213 drives the camera module 30 to deflect relative to the base 10.
In embodiments of the present application, sense layer 212 may both receive external control signals and provide expansion or contraction actuation to vibration layer 213. In practical applications, the external control signals that can be received by the sensing layer 212 include, but are not limited to, optical signals, electrical signals, or magnetic signals, etc., that is, the sensing layer 212 includes, but is not limited to, an optical signal sensing layer 212, an electrical signal sensing layer 212, a magnetic signal sensing layer 212, etc. In the embodiment of the application, the optical signal sensing layer 212, the electrical signal sensing layer 212 and the magnetic signal sensing layer 212 can be non-contact sensing layers 212, so that the wiring difficulty in the camera module can be effectively reduced, and the structure of the camera module is more compact and the volume is smaller.
In the embodiment of the present application, the vibration layer 213 can be extended or contracted under the action of the sensing layer 212, and the deformation force of the vibration layer is used as a driving force to drive the camera module 30 to deflect. In an embodiment of the present application, the vibration layer 213 may specifically include: one of an electrostrictive layer, a magnetostrictive layer, a photo-stretchable layer, or a shape memory alloy layer.
The electrostrictive layer, that is, the piezoelectric material layer, specifically includes, but is not limited to, a piezoelectric single crystal, a piezoelectric polycrystal, a piezoelectric polymer, a piezoelectric composite material, and the like. Principle of electrostrictive layer: when an electric field (or voltage) is applied to the surface of the piezoelectric material, the electric dipole moment is elongated due to the electric field, and the piezoelectric material is elongated in the direction of the electric field to resist the change. This process of mechanical deformation by the action of an electric field is called "electrostriction". Electrostriction is essentially the process of converting electrical energy into mechanical energy. Taking piezoelectric polycrystals as an example, there are spontaneously formed molecular groups, so-called "electric domains", inside which there is a certain polarization, and the length in the polarization direction tends to be different from that in other directions. When an external electric field acts, the electric domains can rotate, so that the polarization direction of the electric domains is consistent with the direction of the external electric field, and the length of the material along the direction of the external electric field is changed to represent elastic strain. This phenomenon is called electrostrictive effect. It can be understood that in the case where the vibration layer 213 is an electrostrictive layer, the sensing layer 212 applies an electric field or voltage control to the electrostrictive layer after receiving an external control signal.
In an embodiment of the present application, the magnetostrictive layer, i.e., the magnetostrictive material layer, includes, but is not limited to, magnetostrictive metals and alloys, such as nickel (Ni) -based alloys (Ni, ni-Co alloys, ni-Co-Cr alloys) and iron-based alloys (such as Fe-Ni alloys, fe-Al alloys, fe-Co-V alloys, etc.), and ferrite magnetostrictive materials, such as Ni-Co and Ni-Co-Cu ferrite materials, etc. Principle of magnetostriction: refers to an object that stretches or shortens in the direction of magnetization when magnetized in a magnetic field. Ferromagnetic materials whose dimensions change significantly when the current through the coil changes or the distance from the magnet changes are commonly referred to as magnetostrictive materials, whose dimensions change much more than current magnetostrictive materials such as ferrites, and whose energy produced is also large, are referred to as giant magnetostrictive materials. In the embodiment of the application, the magnetostrictive layer can be an iron magnetostrictive material layer or a super magnetostrictive material layer. It will be appreciated that in the case where the vibration layer 213 is a magnetostrictive layer, the sensing layer 212 transmits a magnetic signal to the vibration layer 213.
In an embodiment of the present application, the photo-induced telescopic layer includes, but is not limited to, a ferroelectric material layer, a PLZT ceramic (lead lanthanum zirconate titanate ceramic) layer, a photosensitive perovskite layer, and the like. Taking PLZT ceramic as an example, when a high-energy beam irradiates the surface of PLZT ceramic, the PLZT ceramic deforms, which is called photo-induced telescoping effect. It is understood that in the case where the vibration layer 213 is a photo-stretching layer, the sensing layer 212 transmits an optical signal to the vibration layer 213.
In embodiments of the present application, the shape memory alloy layer includes, but is not limited to, tiNi-based shape memory alloys, copper-based shape memory alloys, iron-based shape memory alloys, and the like. Shape memory alloy (Shape Memory Alloys, SMA) is a smart material capable of memorizing an original shape. When the alloy is subjected to a limited plastic deformation at a temperature below the transformation temperature, it can be restored to its original shape before deformation by heating, a special phenomenon known as shape memory effect (Shape Memory Effect, SME). When the alloy is subjected to limited plastic deformation (nonlinear elastic deformation) at a temperature higher than the phase transition temperature, the alloy can be restored to the original shape before deformation by directly releasing the stress, and the special phenomenon is called pseudoelasticity (Pseudo Elasticity, PE) or super-elasticity (Super Elasticity).
In an embodiment of the present application, in order to electrically insulate the sensing layer 212 from the base 10, the anti-shake driving block 21 further includes: an insulating layer 211, the insulating layer 211 being disposed between the susceptor 10 and the sensing layer 212. Of course, in the case that the base 10 is made of an insulating material, the insulating layer 211 may be understood as being integrally formed with the base 10, so that the processing cost of the anti-shake driving film layer 20 may be effectively reduced.
In the embodiment of the present application, the anti-shake driving block 21 further includes: an elastic layer 214; the vibration layer 213 is connected to the camera module 30 through an elastic layer 214, and the elastic layer 214 stretches and contracts along with the stretching or shrinking direction of the vibration layer 213. In an embodiment of the present application, the elastic layer 214 includes, but is not limited to, a metal elastic layer 214.
In the embodiment of the present application, the driving principle of each anti-shake driving module 21 may refer to the driving principle of the ultrasonic motor, specifically, the vibration layer 213 and the elastic layer 214 may correspond to the stator of the ultrasonic motor, and the camera module 30 may correspond to the rotor of the ultrasonic motor, and vice versa. In practical applications, the vibration layer 213 receives an external control signal (optical signal, electrical signal or magnetic signal) through the sensing layer 212, generates multiple sets of standing waves inside the elastic layer 214, synthesizes the traveling waves inside the elastic layer 214, and forms microscopic vibrations with a certain motion track (usually an elliptical track) on the particles on the surface of the elastic layer 214, and the microscopic motions enable the camera module 30 to continuously and macroscopically move along the counter-traveling direction through the friction between the elastic layer 214 and the camera module 30. In the embodiment of the present application, each anti-shake driving block 21 may generate an X-lateral standing wave or a Y-longitudinal standing wave as shown in fig. 2.
The standing wave driving principle of the anti-shake driving mode layer 20 will be briefly described with reference to the drawings.
Referring to fig. 4, a schematic diagram of a standing wave driving principle of the anti-shake driving film according to an embodiment of the application is shown. The elastomer may be understood as the elastic layer 214 according to the embodiment of the present application, the vibration body may be understood as the vibration layer 213 according to the embodiment of the present application, and the moving body may be understood as the camera module 30 according to the embodiment of the present application. As shown in fig. 4, when a high-frequency voltage having a certain phase difference (for example, a phase difference of 90 °) is applied to two adjacent sets of vibrators (for example, a piezoelectric ceramic plate is taken as an example for a vibrator) bonded to an elastomer (Stator Metal), two sets of standing waves (STANDING WAVE) can be generated in the elastomer, and these two sets of standing waves synthesize a traveling Wave (Progressive Wave) traveling in the circumferential direction C of the elastomer, so that particles on the surface of the elastomer form an ultrasonic microscopic vibration with a certain motion track (usually an elliptical track), the vibration of which is typically several micrometers, and the microscopic vibration causes the moving body (Rotor) to perform continuous macroscopic motion in the direction D (counter-traveling Wave propagation direction) in the figure by the friction action between the elastomer (Stator) and the moving body (Rotor).
It can be understood that when the vibrator is made of a photo-induced telescopic material, the applied high-frequency optical signal may be applied, and when the vibrator is made of a magnetostrictive material, the applied high-frequency magnetic signal may be applied, so that other references are executed, and the embodiments of the present application will not be described in detail.
It should be noted that, in the above description of the principle of only generating one direction (the X direction or the Y direction) in the anti-shake driving film layer 20, in the embodiment of the present application, since the anti-shake driving film layer 20 includes a plurality of anti-shake driving modules 21, when high-frequency voltages with different phase differences are applied to the plurality of anti-shake driving modules 21, standing waves with different directions can be generated by the plurality of anti-shake driving modules 21, and further, the directions of macroscopic driving forces applied to the camera module 30 by the plurality of anti-shake driving modules 21 are also different, and the final displacement or the deflection angle of the camera module 30 is generated under the combined action of the driving forces applied by the plurality of anti-shake driving modules 21, so in practical application, a person skilled in the art can apply high-frequency voltages with preset phase differences to the different anti-shake driving modules 21 according to actual requirements, so as to compensate for the position change of the camera caused by shake in the shooting process.
In practical application, in order to improve the reliability of the elastic layer 214 driving the camera module 30 to deflect, the roughness of the contact surface between the elastic layer 214 and the camera module 30 is improved, and a roughening structure may be further disposed at the position between the elastic layer 214 and the camera module 30 or a roughening film layer may be disposed between the elastic layer 214 and the camera module 30, so as to increase the friction between the elastic layer 214 and the camera module 30.
In the embodiment of the present application, each layer in the anti-shake driving block 21 or the anti-shake driving film layer 20 may be manufactured by an adhesion process, a vapor deposition process, or the like. For example, the insulating layer 211 may be disposed on the base 10 by electroplating or chemical vapor deposition, and the elastic layer 214 and the vibration layer 213 may be connected by adhesion, or the like. Specifically, a person skilled in the art may select a suitable manufacturing process according to specific materials of the sensing layer 212, the vibration layer 213, the insulating layer 211 and the elastic layer 214, which is not described herein.
In the embodiment of the present application, the thickness of each film layer (the sensing layer 212, the vibration layer 213, the insulating layer 211, and the elastic layer 214) is set according to actual requirements, which is not limited in the embodiment of the present application.
In the embodiment of the present application, a groove is formed on the base 10, and at least part of the camera module 30 is disposed in the groove; the anti-shake driving film layer 20 is disposed between the wall of the groove and the camera module 30. In the embodiment of the application, the camera module 30 is arranged in the groove, so that the overall structure of the camera module is more compact and smaller, and the connection reliability between the base 10 and the camera module 30 can be improved. It should be noted that, the anti-shake driving film layer 20 covers the wall of the groove and extends along the shape of the groove, so that the volume occupied by the anti-shake driving film layer 20 can be further reduced.
Specifically, the groove may be a spherical groove, at least part of the groove wall of the spherical groove is covered with the anti-shake driving film layer 20, and the anti-shake driving film layer 20 extends along the groove wall of the spherical groove. It can be appreciated that, in the case that the recess is a spherical recess, the camera module 30 is disposed at the position of the recess and is a spheroid matched with the spherical recess, and the anti-shake driving film layer 20 covers the wall of the spherical recess, so that the camera module 30 can be driven to deflect 360 ° in the spherical recess by the anti-shake driving film layer 20.
Referring to fig. 5, a schematic diagram of a camera module of the electronic device shown in fig. 1 in a deflected state is shown. Referring to fig. 6, a schematic diagram of another deflection state of the camera module of the electronic device shown in fig. 1 is shown.
In practical application, when the camera module 30 is used, the camera module 30 can be directly driven to deflect relative to the base 10 by the anti-shake driving module 21 by applying corresponding electric/magnetic/optical signals to each anti-shake driving block 21 in the anti-shake driving film layer 20. For example, when the anti-shake driving block 21 applies an electric/magnetic/optical signal for controlling the camera module 30 to deflect in the a direction, the macro anti-shake driving block 21 applies a driving force in the F1 direction to the camera module 30, and the camera module 30 deflects in the a direction, and the deflection angle can reach 5 ° or more (as shown in fig. 5); when the anti-shake driving block 21 applies an electric/magnetic/optical signal for controlling the camera module 30 to deflect in the B direction, the macro anti-shake driving block 21 applies a driving force in the F2 direction to the camera module 30, and the camera module 30 deflects in the B direction by an angle of 5 ° or more (as shown in fig. 6).
It can be appreciated that, since the anti-shake driving film layer 20 can be uniformly distributed along the wall of the spherical groove, the camera module 30 can deflect 360 ° along the spherical groove without dead angle by individually controlling each anti-shake driving module 21 in the anti-shake driving film layer 20.
In the embodiment of the application, the spherical groove is arranged on the base 10, the camera module 30 is arranged in the shape of the tail hemispherical matched with the spherical groove, and the anti-shake driving film layer 20 is arranged on the groove wall of the spherical groove, so that the deflection angle of the camera module 30 can reach more than or equal to 5 degrees, and the anti-shake performance of the camera can be effectively improved. It should be noted that, in the embodiment of the present application, the deflection angle of the camera module 30 may be understood as a deflection angle of the camera within a range of 360 ° around the optical axis thereof.
It should be noted that, in the embodiment of the present application, the base 10 is provided with a spherical groove, and the camera module 30 is provided with a tail hemispherical shape matched with the spherical groove, so that the camera module 30 can deflect in 360 ° without dead angle in the spherical groove. In practical application, the hemispherical protrusion may be disposed on the base 10, and the spherical groove may be disposed on the camera module 30, so that the structural arrangement of the base 10 and the camera module 30 may be realized by matching the spherical protrusion with the spherical groove.
In the embodiment of the application, the contact area between the camera module 30 and the anti-shake driving film layer 20 is larger, and the structure of the camera module 30 in the groove of the base 10 is more stable, so the camera module in the embodiment of the application has the advantages of space saving, large moment, large static holding force, no shake, high energy conversion efficiency and the like.
In summary, the electronic device according to the embodiment of the application at least includes the following advantages:
in the embodiment of the application, the anti-shake driving film layer is arranged on the base and is connected with the camera module, so that the anti-shake driving film layer extends or contracts on the base to drive the camera module to deflect relative to the base, the occupied space of the anti-shake driving film layer is small, and the expansion or contraction of the anti-shake driving film layer can drive the camera module to deflect at a larger angle in a limited space, so that the shake compensation of a larger deflection angle is realized, and therefore, the anti-shake effect of the electronic equipment is better.
