As shown in fig. 1 to 7, the camera module includes: the lens barrel comprises a lens barrel 10, a shading liquid 20, a light-transmitting liquid 30, an electro-deformation ring 40, a coating liquid film 50, a light-transmitting liquid film 60 and an image sensor 123.
The lens barrel 10 comprises a light inlet end and a light outlet end, wherein the light inlet end is opposite to the light outlet end, the light outlet end is provided with a light-transmitting sealing piece 11, and the light-transmitting sealing piece 11 seals the light outlet end; the lens barrel 10 is provided with a first cavity, the transparent liquid film 60 is located at the light-emitting end, the transparent liquid film 60 is hermetically connected with the inner wall of the lens barrel 10, the transparent liquid film 60 is opposite to the transparent sealing part 11, the transparent liquid film 60 and the transparent sealing part 11 form a second cavity, and the second cavity is communicated with the first cavity. The coating liquid film 50 coats the shading liquid 20, the coating liquid film 50 is positioned in the first cavity, the coating liquid film 50 is close to the light inlet end, the transparent liquid 30 is positioned in the first cavity and the second cavity, and the transparent liquid 30 is close to the light outlet end; the electro-deformation ring 40 is located at the light incident end, and the electro-deformation ring 40 is hermetically connected with the coating liquid film 50. When the electrostrictive ring 40 is electrified, the inner diameter of the electrostrictive ring 40 is larger than the initial value, the surface of the light-transmitting liquid film 60 facing the image sensor 123 is an arc surface, and the bending direction of the arc surface is a direction facing the light incident end; in the case where the electrostrictive ring 40 is deenergized, the inner diameter of the electrostrictive ring 40 returns to the initial value, and the surface of the light-transmitting liquid film 60 facing the image sensor 123 returns to the flat surface.
In the embodiment of the present application, since the lens barrel 10 includes the light entrance end and the light exit end, and the light exit end is provided with the light-transmissive sealing member 11, the light exit end is sealed by the light-transmissive sealing member 11, the lens barrel 10 has the first cavity, the light-transmissive liquid film 60 is located at the light exit end, the light-transmissive liquid film 60 is hermetically connected to the inner wall of the lens barrel 10, and the light-transmissive liquid film 60 is opposite to the light-transmissive sealing member 11, so that the light-transmissive liquid film 60 can form the second cavity by the light-transmissive sealing member 11, and the second cavity is communicated with the first cavity. Because the coating liquid film 50 coats the shading liquid 20, the coating liquid film 50 is located in the first cavity, the coating liquid film 50 is close to the light incident end, the transparent liquid 30 is located in the first cavity and the second cavity, the transparent liquid 30 is close to the light emitting end, the electrostrictive ring 40 is located at the light incident end, and the electrostrictive ring 40 is hermetically connected with the coating liquid film 50, when the electrostrictive ring 40 is electrified, the form of the electrostrictive ring 40 changes, that is, the electrostrictive ring 40 extends or contracts, so that the electrostrictive ring 40 can extrude the coating liquid film 50, the shading liquid 20 in the coating liquid film 50 flows, and the coating liquid film 50 can extrude the transparent liquid 30, and the transparent liquid 30 flows. When the transparent liquid 30 flows, the transparent liquid 30 can apply a force to the transparent sealing member 11 and the transparent liquid film 60, but the shape of the transparent sealing member 11 does not change, so the transparent liquid film 60 can be deformed under the action of the transparent liquid 30, and the focal length of the camera module changes. Specifically, under the condition that the electrostrictive ring 40 is electrified, the electrostrictive ring 40 extends, the inner diameter of the electrostrictive ring 40 is increased, so that the inner diameter of the electrostrictive ring 40 is larger than the initial value, at this time, the electrostrictive ring 40 presses the coating liquid film 50, so that the shading liquid 20 in the coating liquid film 50 flows, further, the position of the coating liquid film 50 moves, so that the coating liquid film 50 moves to a target position, in the moving process of the coating liquid film 50, the coating liquid film 50 presses the transparent liquid 30, so that the transparent liquid film 30 presses the transparent liquid film 60, and the transparent liquid film 60 deforms, namely, the surface of the transparent liquid film 60 facing the image sensor 123 is an arc surface, and the curvature of the surface of the transparent liquid film 60 changes, so that the focal length of the camera module changes; under the condition that the electrostrictive ring 40 is powered off, the electrostrictive ring 40 contracts, the inner diameter of the electrostrictive ring 40 becomes small, and the inner diameter of the electrostrictive ring 40 is restored to an initial value, at the moment, the electrostrictive ring 40 releases the extrusion on the coating liquid film 50, the transparent liquid 30 can apply force to the coating liquid film 50, namely, the transparent liquid 30 drives the coating liquid film 50 to move, so that the coating liquid film 50 is restored to the initial position, and further the surface of the transparent liquid film 60 facing the image sensor 123 is restored to a plane.
That is, in the embodiment of the present application, the electrostrictive ring 40 is powered on or powered off, so that the electrostrictive ring 40 can extrude the cladding liquid film 50, thereby causing the light-shielding liquid 20 to flow, thereby causing the light-transmitting liquid 30 to flow so as to extrude the light-transmitting liquid 30, thereby causing the light-transmitting liquid film 60 to deform, that is, the surface of the light-transmitting liquid film 60 changes, thereby causing the curvature of the light-transmitting liquid film 60 to change, further causing the camera module to focus, and causing the camera module to focus more easily.
In the embodiment of the present application, since the coating liquid film 50 coats the light-shielding liquid 20, the problem of leakage of the light-shielding liquid 20 can also be prevented. In addition, in the embodiment of the present application, when the camera module shoots, at this time, the light passes through the inner space of the electrostrictive ring 40, and further passes through the transparent liquid film 60, the transparent liquid 30 and the transparent sealing member 11, so that the light can be transmitted continuously.
In addition, in the embodiment of the present application, the initial value may be a numerical value of the inner diameter of the lens barrel when the lens barrel is not energized. In addition, when the transparent liquid film 60 is in the initial state, the surface of the transparent liquid film 60 may be a plane, and certainly, the surface may also be a cambered surface, which is not limited herein in the embodiment of the present application. When the transparent liquid film 60 is in the initial state, and the surface of the transparent liquid film 60 is an arc surface, at this time, the curvature of the arc surface is smaller than that of the arc surface when the electrostrictive ring 40 is electrified.
In addition, in the embodiment of the present application, when the inner diameter of the electrostrictive ring 40 becomes larger, the space through which light can pass becomes larger, that is, the aperture of the light becomes larger. When the inner diameter of the electrostrictive ring 40 becomes small, the space through which light can pass becomes small, that is, the aperture of light becomes small.
In addition, in the embodiment of the present application, the material of the light-transmitting sealing member 11 may be glass, but of course, other light-transmitting materials may also be used, and the embodiment of the present application is not limited herein.
It should be noted that, in the embodiment of the present application, different voltages may be applied to the electrostrictive ring 40, and the deformation amounts of the electrostrictive ring 40 are different, that is, the squeezing effects of the electrostrictive ring 40 on the coating liquid film 50 are also different, so that the curvatures of the transparent liquid film 60 are also different, and the camera module can achieve multiple focusing effects.
In addition, in the embodiment of the present application, a material of the transparent liquid film 60 may be selected according to actual needs, as long as the material can realize light transmission, and thus, the embodiment of the present application is not limited herein. In addition, in the embodiment of the present application, the transparent liquid film 60 may also have a certain elasticity, and at this time, when the electric deformation ring 40 is powered on and the electric deformation ring 40 presses the coating liquid film 50, that is, the electric deformation ring 40 applies a force to the coating liquid film 50, the light-shielding liquid 20 in the coating liquid film 50 may flow, so as to flow the transparent liquid 30, and finally deform the transparent liquid film 60, so as to change the curvature of the surface of the transparent liquid film 60. When the electric deformation ring 40 is powered off and the electric deformation ring 40 releases the extrusion on the coating liquid film 50, at this time, the transparent liquid film 60 can apply force to the transparent liquid 30 by virtue of the elasticity of the transparent liquid film 60, so that the transparent liquid 30 flows, and the transparent liquid film 60 is restored to the initial state.
In the embodiment of the present application, when the electric current is applied to the electrostrictive ring 40, the electrostrictive ring 40 may be changed in shape, that is, the inner diameter of the electrostrictive ring 40 may be increased. Upon cessation of power to the electro-deformable ring 40, i.e., upon de-energization of the electro-deformable ring 40, the electro-deformable ring 40 may return to the original state.
In the embodiment of the present application, the material of the electrostrictive ring 40 may be an electrostrictive material, such as piezoelectric ceramics, which mainly includes lead magnesium niobate ceramics, lead lanthanum zirconate titanate ceramics, and the like. Of course, the material of the electrostrictive ring 40 may also be other electrostrictive materials, and the present application is not limited thereto.
Additionally, in some embodiments, the camera module may further include a light-transmissive cover film (not shown). The transparent coating film is coated with the transparent liquid 30, and the transparent coating film is located in the first cavity and the second cavity.
When the camera module includes the printing opacity coating film, during printing opacity coating film cladding printing opacity liquid 30, and the printing opacity coating film is arranged in first cavity and second cavity, at this moment, when the circular telegram of electrogenerated deformation circle 40, electrogenerated deformation circle 40 extends, the internal diameter grow of electrogenerated deformation circle 40 for coating liquid film 50 can be to the printing opacity coating film application of force, make printing opacity liquid 30 in the printing opacity coating film flow, and then printing opacity liquid 30 can be to printing opacity liquid film 60 application of force, make printing opacity liquid film 60 warp. Since the light-transmissive coating film is light-transmissive, light can continue to pass through the light-transmissive coating film and the light-transmissive liquid 30 and finally through the light-transmissive enclosure 11 as the light passes through the light-transmissive liquid film 60. In addition, the problem of leakage of the transparent liquid 30 can be avoided because the transparent coating film coats the transparent liquid 30.
It should be noted that, the material of the light-transmitting coating film may be made of a light-transmitting material according to actual needs, and the embodiment of the present application is not limited herein.
Additionally, in some embodiments, as shown in fig. 1 or 2, the camera module may further include a bumper ring 130. The barrier ring 130 is located in the first cavity, and the barrier ring 130 is located at a boundary between the coating liquid film 50 and the transparent liquid 30.
When the camera module includes the barrier ring 130, and the barrier ring 130 is located at a boundary between the coating liquid film 50 and the transparent liquid 30, at this time, when the electrostrictive ring 40 is powered on, the electrostrictive ring 40 extends, and a force is applied to the coating liquid film 50, the coating liquid film 50 can apply a force to the barrier ring 130, and a force is applied to the transparent liquid 30 through the barrier ring 130, so that a force is applied to the transparent liquid 30, and the transparent liquid 30 can flow conveniently. In addition, the barrier ring 130 can also serve to isolate the light-shielding liquid 20 from the transparent liquid 30.
In addition, in the embodiment of the present application, when the camera module includes the light-transmitting coating film, the barrier ring 130 may be located between the coating liquid film 50 and the light-transmitting coating film, so as to function as the barrier coating liquid film 50 and the light-transmitting coating film.
Additionally, in some embodiments, as shown in fig. 1 or 2, the camera module may further include a protective sleeve 70. The protective cylinder 70 is sleeved on the lens barrel 10, and the inner wall of the protective cylinder 70 is electrically connected with the outer wall of the electrostrictive ring 40.
When the camera module includes the protection cylinder 70 and the protection cylinder 70 is sleeved on the lens barrel 10, at this time, the protection cylinder 70 can protect the lens barrel 10, and the lens barrel 10 is prevented from being damaged by external force. In addition, since the inner wall of the protection cylinder 70 is electrically connected to the electrostrictive ring 40, electricity can be supplied to the electrostrictive ring 40 through the protection cylinder 70, so that the protection cylinder 70 transmits electricity to the electrostrictive ring 40, thereby changing the form of the electrostrictive ring 40. That is, by providing the protection cylinder 70, not only the electrostrictive ring 40 can be protected, but also the electrostrictive ring 40 can be easily energized, so that the form of the electrostrictive ring 40 changes.
It should be noted that the inner diameter of the protection cylinder 70 is larger than the outer diameter of the lens barrel 10, and a preset distance may be provided between the inner wall of the protection cylinder 70 and the outer wall of the lens barrel 10, so that the protection cylinder 70 is conveniently sleeved on the lens barrel 10.
In addition, in the embodiment of the present application, the inner wall of the protection cylinder 70 and the electrostrictive ring 40 may be electrically connected in a manner that: as shown in fig. 1 or fig. 2, the inner wall of the protective cylinder 70 and the electrostrictive ring 40 may be electrically connected through an elastic conductive member 71.
When the inner wall of the protection cylinder 70 is electrically connected to the electrostrictive ring 40 through the elastic conductive member 71, at this time, when the protection cylinder 70 is powered on, the protection cylinder 70 may transmit electric energy to the elastic conductive member 71, the elastic conductive member 71 transmits electric energy to the electrostrictive ring 40, so that the form of the electrostrictive ring 40 changes, and when the form of the electrostrictive ring 40 changes, the electrostrictive ring 40 may apply force to the elastic conductive member 71, so that the elastic conductive member 71 deforms. In addition, when the power supply to the protection cylinder 70 is stopped, that is, when the protection cylinder 70 is powered off, in this case, it is equivalent to the power off of the electrostrictive ring 40, in this case, the elastic conductive member 71 may apply a force to the electrostrictive ring 40, so that the electrostrictive ring 40 can be quickly restored to the initial state. That is, the inner wall of the protection cylinder 70 and the electrostrictive ring 40 are electrically connected through the elastic conductive member 71, so that not only can the electrostrictive ring 40 be powered on or powered off, but also the electrostrictive ring 40 can be quickly restored to the initial state in the case of power failure.
It should be noted that the elastic conductive member 71 may be a conductive spring, and of course, other devices, such as a conductive elastic sheet, may also be used, and the embodiment of the present invention is not limited herein.
In addition, when the inner wall of the protection cylinder 70 and the electrostrictive ring 40 are electrically connected through the elastic conductive member 71, a first end of the elastic conductive member 71 may be connected to the inner wall of the protection cylinder 70, and a second end of the elastic conductive member 71 may be connected to the electrostrictive ring 40, wherein the first end and the second end of the elastic conductive member 71 are opposite.
Of course, the inner wall of the protection cylinder 70 may be electrically connected to the electrostrictive ring 40 in other manners, for example, the inner wall of the protection cylinder 70 is connected to the electrostrictive ring 40 by a wire, and the embodiment of the present application is not limited herein as to the manner in which the inner wall of the protection cylinder 70 is electrically connected to the electrostrictive ring 40.
In addition, in some embodiments, as shown in fig. 7, the number of the elastic conductive members 71 may be plural. A plurality of elastic conductive members 71 are disposed at equal intervals along the circumferential direction of the protection cylinder 70, and a first end of the elastic conductive member 71 is connected to the inner wall of the protection cylinder 70 and a second end of the elastic conductive member 71 is connected to the electrostrictive ring 40.
When the number of the elastic conductive members 71 is plural and the plural elastic conductive members 71 are arranged at equal intervals along the circumferential direction of the protection cylinder 70, at this time, it is equivalent to that the plural elastic conductive members 71 simultaneously fix the electrostrictive ring 40, so that when the electrostrictive ring 40 is powered off, the elastic conductive members 71 can apply a relatively uniform force to the electrostrictive ring 40, and when the electrostrictive ring 40 is powered on, the electrostrictive ring 40 applies a uniform force to the elastic conductive members 71, so that the electrostrictive ring 40 can be always located at the center position of the protection cylinder 70. That is, by providing a plurality of elastic conductive members 71 and arranging the plurality of elastic conductive members 71 at equal intervals between the inner wall of the protective cylinder 70 and the outer wall of the electrostrictive ring 40 in the circumferential direction of the electrostrictive ring 40, the electrostrictive ring 40 can be secured at the center position of the protective cylinder 70.
It should be noted that the number of the elastic conductive elements 71 may be set according to actual needs, for example, the number of the elastic conductive elements 71 may be 4, or may also be 8, and the number of the elastic conductive elements 71 is not limited herein.
