Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the 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 view of a lens barrel in a camera module according to an embodiment of the present application is shown; referring to fig. 2, a schematic diagram illustrating shrinkage of a lens barrel in a camera module according to an embodiment of the present application is shown; referring to fig. 3, a schematic diagram of a lens barrel shrinkage variation in a camera module according to an embodiment of the present application is shown; referring to fig. 4, a schematic diagram of connection between 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 light-transmitting liquid 30, and the wrapping film 20 is located in the lens barrel 10. When the lens barrel 10 is electrified, the inner diameter of the lens barrel 10 is smaller than an initial value, the surface of the whole formed by the light-transmitting liquid 30 and the wrapping film 20, which faces the image sensor 93, is an arc surface, and the bending direction of the arc surface is the direction facing the outer 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 whole body of the light-transmitting liquid 30 and the wrapping film 20 returns to the plane toward the surface of the image sensor 93.
In the embodiment of the present application, since the wrapping film 20 wraps the light-transmitting liquid 30 and the wrapping film 20 is located in the electro-deformable lens barrel 10, when the electro-deformable lens barrel 10 is electrified, the shape of the electro-deformable lens barrel 10 will change, and when the shape of the electro-deformable lens barrel 10 changes, the inner wall of the lens barrel 10 will press the wrapping film 20, or the pressing of the wrapping film 20 will be released, so that the light-transmitting 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 electrified, 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 light-transmitting liquid 30 flows in the wrapping film 20, the whole formed by the light-transmitting liquid 30 and the wrapping film is deformed, namely the whole formed by the light-transmitting liquid 30 and the wrapping film 20 faces the surface of the image sensor 93 to be an arc surface, namely the curvature of the wrapping film 20 is changed, and the camera module can be focused; in the case where the lens barrel 10 is powered off, the lens barrel 10 may be stretched, the inner diameter of the lens barrel 10 becomes large, so that the inner diameter of the lens barrel 10 is restored to the initial value, the inner wall of the lens barrel 10 is released from the extrusion of the wrapping film 20, so that the light-transmitting liquid 30 flows in the wrapping film 20, so that the whole formed by the light-transmitting liquid 30 and the wrapping film 20 is restored to the initial state toward the surface of the image sensor 93, i.e., the wrapping film 20 is restored to the plane. That is, in the embodiment of the present application, the light-transmitting liquid 30 is coated by the coating film 20, and the coating film 20 is placed in the electrically deformable lens barrel 10, so that the shape of the lens barrel 10 can be changed under the condition that the lens barrel 10 is electrified, so that the curvature of the coating film 20 is changed, and further, the camera module is focused, so that the camera module can be focused more simply.
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 the deformation amounts of the electro-deformable lens barrel 10 are different, that is, the extrusion effects of the electro-deformable lens barrel 10 on the wrapping film 20 are different, so that the curvatures of the wrapping film 20 are different, and the camera module may achieve multiple focusing effects. In addition, in the embodiment of the present application, the initial value may be a 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 light-transmitting liquid 30, and the wrapping film 20 is located in the lens barrel 10 that is electrically deformed, and this structure may be referred to as a liquid lens.
In addition, in the embodiment of the present application, the material of the wrapping film 20 may be selected according to actual needs, as long as the material capable of transmitting light can be achieved, and the embodiment of the present application is not limited herein. In addition, in the embodiment of the present application, the wrapping film 20 may also have a certain elasticity, and when the lens barrel 10 is electrified 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 force to the wrapping film 20, the light-transmitting 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, the inner wall of the lens barrel 10 releases the extrusion of the wrapping film 20, at this time, the wrapping film 20 can apply force to the light-transmitting liquid 30 by virtue of the elasticity of the wrapping film 20, so that the light-transmitting liquid 30 flows, and the wrapping film 20 is restored to the initial state.
In addition, in the embodiment of the present application, when the electric power is applied to the barrel 10 that is electrically deformed, the barrel 10 may undergo a shape change, that is, the inner diameter of the barrel 10 becomes smaller. When the energization of the electro-deformable lens barrel 10 is stopped, that is, when the electro-deformable lens barrel 10 is powered off, the lens barrel 10 can be restored to the original state.
In the embodiment of the present application, the material of the electro-deformable lens barrel 10 may be electro-deformable material, for example, piezoelectric ceramic, and mainly includes lead magnesium niobate ceramic, lead lanthanum zirconate titanate ceramic, and the like. Of course, the material of the electro-deformable lens barrel may be other electro-deformable materials, which is not limited herein.
In addition, in the embodiment of the present application, when the camera module shoots, the light can pass through the wrapping film 20 and the light-transmitting liquid 30, so that when the inner diameter of the electrically deformed lens barrel 10 is electrified and becomes smaller, the aperture diameter of the light becomes smaller, and when the electrically deformed lens barrel 10 is powered off and the inner diameter becomes larger, 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.
Additionally, in some embodiments, as shown in fig. 1 or 2, the camera module may further include a protective barrel 40. The protection tube 40 is sleeved on the lens barrel 10, and the inner wall of the protection tube 40 is electrically connected with the outer wall of the lens barrel 10.
When the camera module comprises the protection cylinder 40 and the protection cylinder 40 is sleeved on the lens barrel 10, the protection cylinder 40 can protect the lens barrel 10 and prevent the lens barrel 10 from being damaged by external force. 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 is changed. That is, by providing the protection tube 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 is changed.
It should be noted that, the inner diameter of the protection tube 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 tube 40 and the outer wall of the lens barrel 10, so that the protection tube 40 is conveniently sleeved on the lens barrel 10.
In addition, in the embodiment of the present application, the manner in which the inner wall of the protection cylinder 40 is electrically connected to the outer wall of the lens barrel 10 may be: the inner wall of the protection cylinder 40 and the outer wall of the lens barrel 10 may be electrically connected by an elastic conductive member 41.
When the inner wall of the protection cylinder 40 is electrically connected with the lens barrel 10 through the elastic conductive member 41, at this time, when the protection cylinder 40 is energized, the protection cylinder 40 can transfer electric energy to the elastic conductive member 41, the elastic conductive member 41 transfers electric energy to the lens barrel 10 so that the shape of the lens barrel 10 changes, and when the shape of the lens barrel 10 changes, the lens barrel 10 can apply force to the elastic conductive member 41 so that the elastic conductive member 41 deforms. In addition, when the power supply to the protective cylinder 40 is stopped, that is, the protective cylinder 40 is powered off, at this time, which corresponds 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 original state. That is, the inner wall of the protection cylinder 40 is electrically connected with the outer wall of the lens barrel 10 through the elastic conductive member 41, so that not only the power on or 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 power off condition.
It should be noted that the elastic conductive member 41 may be a conductive spring, and of course, may be other devices, such as a conductive spring sheet, which is not limited herein.
In addition, when the inner wall of the protection cylinder 40 and the outer wall of the lens barrel 10 are electrically connected through the elastic conductive member 41, at this time, the first end of the elastic conductive member 41 may be connected with the inner wall of the protection cylinder 40, and the second end of the elastic conductive member 41 may be connected with the outer wall of the lens barrel 10, wherein the first end and the second end of the elastic conductive member 41 are opposite.
Of course, the inner wall of the protection barrel 40 may be electrically connected to the outer wall of the lens barrel 10 in other manners, for example, the inner wall of the protection barrel 40 is connected to the outer wall of the lens barrel 10 through a wire, and the embodiment of the application is not limited herein.
In addition, in some embodiments, as shown in fig. 4, the number of the elastic conductive members 41 may be plural. Along the circumference of the lens barrel 10, a plurality of elastic conductive members 41 are arranged between the inner wall of the protective barrel 40 and the outer wall of the lens barrel 10 at equal intervals, and a first end of the elastic conductive member 41 is connected with the inner wall of the protective barrel 40, and a second end of the elastic conductive member 41 is connected with the outer wall of the lens barrel 10.
When the number of the elastic conductive members 41 is plural and the elastic conductive members 41 are disposed between the inner wall of the protective cylinder 40 and the outer wall of the lens barrel 10 at equal intervals along the circumferential direction of the lens barrel 10, at this time, the elastic conductive members 41 are equivalent to the plural elastic conductive members 41 to fix the lens barrel 10 at the same time, so that the elastic conductive members 41 can apply a relatively uniform force to the lens barrel 10 when the lens barrel 10 is powered off, and the lens barrel 10 can apply a uniform force to the elastic conductive members 41 when the lens barrel 10 is powered on, so that the lens barrel 10 can be always positioned at the center of the protective cylinder 40. That is, by providing the plurality of elastic conductive members 41, and arranging the plurality of elastic conductive members 41 at equal intervals between the inner wall of the protective cylinder 40 and the outer wall of the lens cylinder 10 in the circumferential direction of the lens cylinder 10, the lens cylinder 10 can be ensured to be at the center position of the protective cylinder 40.
It should be noted that, the number of the elastic conductive elements 41 may be set according to actual needs, for example, the number of the elastic conductive elements 41 may be 4 or 8, and the number of the elastic conductive elements 41 is not limited herein.
Additionally, in some embodiments, as shown in fig. 1 or 2, the camera module may further include a light-transmissive cover plate 50. The light-transmitting cover plate 50 is connected to the first end of the protective cylinder 40, and the light-transmitting cover plate 50 contacts the wrapping film 20 so that the wrapping film 20 is in a flat state at the first end of the protective cylinder 40.
When the camera module includes the light-transmitting cover plate 50 and the light-transmitting cover plate 50 is connected to the first end of the protection cylinder 40, the light-transmitting cover plate 50 may contact the wrapping film 20 at this time, so that the first end of the light-transmitting protection cylinder 40 may be in a flat state, that is, the wrapping film 20 contacts the light-transmitting cover plate 50, so that the first end of the protection cylinder 40 is in a planar state. In addition, when the light-transmitting cover plate 50 contacts with the wrapping film 20, and the first end of the protecting cylinder 40 is in a flat state, at this time, when the lens barrel 10 is electrified, the lens barrel 10 is contracted, the inner diameter of the lens barrel 10 is reduced, the inner wall of the lens barrel 10 presses the wrapping film 20, the wrapping film 20 is blocked by the light-transmitting cover plate 50 at the first end of the protecting cylinder 40, the wrapping film 20 is prevented from being deformed, the wrapping film 20 is deformed at the second end of the protecting cylinder 40, and therefore, the wrapping film 20 only has one side curvature change, and the camera module is convenient to focus. In addition, since the light-transmitting cover plate 50 is connected with the first end of the protection cylinder 40, the light-transmitting cover plate 50 contacts with the wrapping film 20, and the light-transmitting cover plate 50 can also protect the wrapping film 20 to prevent the wrapping film 20 from being damaged. That is, by providing the light-transmitting cover plate 50, not only focusing of the camera module can be facilitated, but also protection of the wrapping film 20 can be achieved.
It should be noted that, in the embodiment of the present application, the material of the transparent cover 50 may be glass, and of course, may be other transparent materials, such as sapphire, which is not limited herein.
Additionally, in some embodiments, as shown in fig. 1 or 2, the camera module may also include a lens assembly 60. The lens assembly 60 includes a lens group 61 and a movable lens barrel 62, the lens group 61 is located in the movable lens barrel 62, and the movable lens barrel 62 is connected with the second end of the protection barrel 40.
When the camera module includes the lens assembly 60, the lens assembly 60 includes the lens group 61 and the movable lens barrel 62, and the lens group 61 is located in the movable lens barrel 62, when the movable lens barrel 62 is connected with the second end of the protection barrel 40, at this time, when the camera module focuses, or when the camera module shoots, light can first pass through the transparent cover plate 50 along the direction from the first end to the second end of the protection barrel 40, then pass through the wrapping film 20 and the transparent liquid 30, and further irradiate the lens, when the lens barrel 10 is electrified, the inner wall of the lens barrel 10 extrudes the wrapping film 20, so that the shape of the wrapping film 20 changes, that is, the curvature of the wrapping film 20 at the second end of the protection barrel 40 changes, and thus the wrapping film 20 and the lens group 61 jointly achieve the effect of focus change. That is, by providing the lens assembly 60, the camera module can be advantageously used to achieve the effect of varying the focal length.
It should be noted that the lens group 61 may include a plurality of lenses, and the plurality of lenses are disposed in the lens barrel 10 at intervals along the axial direction of the movable lens barrel 62. For example, the lens group 61 may include three lenses that are disposed in the lens barrel 10 at intervals in the axial direction of the movable lens barrel 62. The number of lenses is not limited in this embodiment.
Additionally, in some embodiments, as shown in fig. 1 or 2, the camera module may further include a driver 70.
