All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Referring to fig. 1, a schematic diagram illustrating that a lens barrel in a camera module provided in an embodiment of the present application is not retracted is shown; referring to fig. 2, a schematic diagram illustrating a lens barrel in a camera module according to an embodiment of the present application is shown; referring to fig. 3, a schematic diagram illustrating a lens barrel shrinkage change in a camera module according to an embodiment of the present application is shown; referring to fig. 4, a schematic diagram of a lens barrel and a conductive elastic member according to an embodiment of the present application is shown. As shown in fig. 1 to 4, the camera module includes: an electro-deformable lens barrel 10, a wrapping film 20, an image sensor 93 and a light-transmitting liquid 30.
The wrapping film 20 wraps the transparent liquid 30, and the wrapping film 20 is located in the lens barrel 10. When the lens barrel 10 is powered on, the inner diameter of the lens barrel 10 is smaller than the initial value, the surface of the whole formed by the transparent liquid 30 and the wrapping film 20, which faces the image sensor 93, is an arc, and the bending direction of the arc is a direction facing the external space of the lens barrel 10; when the lens barrel 10 is powered off, the inner diameter of the lens barrel 10 returns to the initial value, and the surface of the whole formed by the transparent liquid 30 and the coating film 20 facing the image sensor 93 returns to a flat surface.
In the embodiment of the present application, since the wrapping film 20 wraps the transparent liquid 30, and the wrapping film 20 is located in the lens barrel 10, when the lens barrel 10 is powered on, the shape of the lens barrel 10 is changed, and when the shape of the lens barrel 10 is changed, the inner wall of the lens barrel 10 presses the wrapping film 20, or releases the pressing on the wrapping film 20, so that the transparent liquid 30 in the wrapping film 20 flows, and the wrapping film 20 can be deformed. Specifically, under the condition that the lens barrel 10 is powered on, the lens barrel 10 can be retracted, the inner diameter of the lens barrel 10 is reduced, so that the inner diameter of the lens barrel 10 is smaller than an initial value, in the process that the inner diameter of the lens barrel 10 is reduced, the inner wall of the lens barrel 10 presses the wrapping film 20, so that the transparent liquid 30 flows in the wrapping film 20, the whole formed by the transparent liquid 30 and the wrapping film 20 is deformed, that is, the surface of the whole formed by the transparent liquid 30 and the wrapping film 20, which faces the image sensor 93, is an arc surface, that is, the curvature of the wrapping film 20 is changed, and thus the camera module can be focused; in the case where the lens barrel 10 is powered off, the lens barrel 10 may be extended, the inner diameter of the lens barrel 10 becomes large, so that the inner diameter of the lens barrel 10 returns to the initial value, the inner wall of the lens barrel 10 releases the pressing of the wrapping film 20, so that the transparent liquid 30 flows in the wrapping film 20, so that the whole formed by the transparent liquid 30 and the wrapping film 20 returns to the initial state toward the surface of the image sensor 93, that is, the wrapping film 20 returns to a flat surface. That is, in this embodiment of the application, the transparent liquid 30 is coated by the coating film 20, and the coating film 20 is placed in the lens barrel 10 with the electrostriction, so that the form of the lens barrel 10 can be changed when the lens barrel 10 is powered on, and the curvature of the coating film 20 can be changed, and then the camera module is focused, so that the camera module can be focused more simply and conveniently.
It should be noted that, in the embodiment of the present application, different voltages may be applied to the electro-deformable lens barrel 10, and deformation amounts of the electro-deformable lens barrel 10 are different, that is, extrusion effects of the electro-deformable lens barrel 10 on the wrapping film 20 are also different, so that curvatures of the wrapping film 20 are also different, and the camera module can achieve various focusing effects. 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 10 when the lens barrel 10 is not energized.
In addition, in the embodiment of the present application, the wrapping film 20 wraps the transparent liquid 30, and the wrapping film 20 is located in the lens barrel 10 with electrostriction, in this case, this structure may be referred to as a liquid lens.

In addition, in the embodiment of the present application, the wrapping film 20 may also have a certain elasticity, and at this time, when the lens barrel 10 is powered on and the inner wall of the lens barrel 10 presses the wrapping film 20, that is, the inner wall of the lens barrel 10 applies a force to the wrapping film 20, the transparent liquid 30 in the wrapping film 20 may flow, so that the curvature of the surface of the wrapping film 20 changes. When the lens barrel 10 is powered off and the inner wall of the lens barrel 10 releases the extrusion on the wrapping film 20, at this time, the wrapping film 20 can apply force to the transparent liquid 30 by virtue of the elasticity of the wrapping film 20, so that the transparent liquid 30 flows, and the wrapping film 20 is restored to the initial state.
In the embodiment of the present application, when power is applied to the lens barrel 10 that is electrically deformable, the lens barrel 10 may be changed in shape, that is, the inner diameter of the lens barrel 10 may be reduced. When the power supply to the electro-deformable lens barrel 10 is stopped, that is, the electro-deformable lens barrel 10 is powered off, the lens barrel 10 may be restored to the original state.
In the embodiment of the present application, the material of the lens barrel 10 with electrostriction may be electrostriction, 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 lens barrel with electrostriction may also be other materials with electrostriction, and the embodiment of the present application is not limited herein.
In addition, in the embodiment of the present application, when the camera module shoots, light can pass through the wrapping film 20 and the transparent liquid 30, so that when the inner diameter of the lens barrel 10 is decreased when the lens barrel is powered on, the aperture diameter of the light becomes smaller, and when the inner diameter of the lens barrel 10 is increased when the lens barrel is powered off, the aperture diameter of the light becomes larger. The wrapping film 20 may be made of a light-transmitting material, that is, the wrapping film 20 may allow light to pass through.

In addition, since the inner wall of the protection cylinder 40 is electrically connected to the outer wall of the lens barrel 10, the lens barrel 10 can be energized through the protection cylinder 40, so that the protection cylinder 40 transmits electricity to the lens barrel 10, and the form of the lens barrel 10 changes. That is, by providing the protection cylinder 40, not only the lens barrel 10 can be protected, but also the power supply to the lens barrel 10 can be facilitated, so that the form of the lens barrel 10 changes.
It should be noted that the inner diameter of the protection cylinder 40 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 40 and the outer wall of the lens barrel 10, so that the protection cylinder 40 is conveniently sleeved on the lens barrel 10.
In addition, in the embodiment of the present application, the inner wall of the protection cylinder 40 and the outer wall of the lens barrel 10 may be electrically connected in a manner that: the inner wall of the protective cylinder 40 and the outer wall of the lens barrel 10 may be electrically connected through an elastic conductive member 41.

In addition, when the power supply to the protection barrel 40 is stopped, that is, the protection barrel 40 is powered off, in this case, corresponding to the power off of the lens barrel 10, in this case, the elastic conductive member 41 may apply a force to the lens barrel 10, so that the lens barrel 10 may be quickly restored to the initial state. That is, the inner wall of the protection barrel 40 is electrically connected to the outer wall of the lens barrel 10 through the elastic conductive member 41, so that not only the power on or power off of the lens barrel 10 can be realized, but also the lens barrel 10 can be quickly restored to the initial state under the condition of power off.

That is, by providing a plurality of elastic conductive members 41, and providing the plurality of elastic conductive members 41 between the inner wall of the protective cylinder 40 and the outer wall of the lens barrel 10 at equal intervals in the circumferential direction of the lens barrel 10, the lens barrel 10 can be secured at the center position of the protective cylinder 40.
