First embodiment

Referring to fig. 2, in the first embodiment of the present application, the camera module 100 includes a housing 300, a lens structure 400, and an image sensor 500. The lens structure 400 and the image sensor 500 are respectively mounted on the base 300, and are positioned, supported and protected by the base 300. The lens structure 400 at least includes a lens group 410, a first liquid lens 421 and a second liquid lens 423, the lens group 410, the first liquid lens 421 and the second liquid lens 423 are respectively mounted on the base 300, the lens group 410 includes one or more lenses, the lenses in the lens group 410 are made of resin or glass or other materials, the lenses in the lens group 410 have a fixed shape and structure, and the lens group 410 has an optical axis 411. The first liquid lens 421 and the second liquid lens 423 respectively include a liquid capable of transmitting light, and the liquid is capable of flowing and deforming to change the angle of the emergent light. The image sensor 500 is disposed on the base 300, and ambient light can pass through the lens assembly 410, the first liquid lens 421 and the second liquid lens 423 and enter the image sensor 500, so as to convert an ambient light signal into an electrical signal, and an image of a photographed object can be formed after further processing.

Referring to fig. 2, the first liquid lens 421 and the second liquid lens 423 are disposed adjacent to each other, and the first liquid lens 421, the second liquid lens 423, the lens group 410, and the image sensor 500 are disposed in this order from the object side to the image side along the optical axis 411. Further, the camera module 100 includes a circuit board 600, the circuit board 600 and the base 300 form a mounting cavity 101, and the image sensor 500 is disposed in the mounting cavity 101 and electrically connected to the circuit board 600. The circuit board 600 may be further electrically connected to a main board of the terminal device 10, so as to transmit the image data collected by the camera module 100 to a processor of the terminal device 10 for further processing.

Referring to fig. 2, in some embodiments, the camera module 100 includes a filter 700 disposed on the base 300, and the filter 700 is located between the lens structure 400 and the image sensor 500. The optical filter 700 can reflect or absorb infrared light to reduce infrared light incident to the image sensor 500 or prevent infrared light from being incident to the image sensor 500, so as to improve the shooting quality of the camera module 100. In other embodiments, the liquid of the first liquid lens 421 or the second liquid lens 423 can filter infrared light. For example, the liquid of the liquid lens contains phosphate or fluorophosphate or other substances, which can absorb infrared light to reduce the infrared light incident to the image sensor 500 or prevent the infrared light from being incident to the image sensor 500, thereby improving the shooting quality of the camera module 100. Alternatively, the first liquid lens 421 or the second liquid lens 423 include an IR film layer disposed on the surface of the liquid lens for reflecting or absorbing infrared light, so as to reduce the infrared light incident on the image sensor 500 or prevent the infrared light from being incident on the image sensor 500, thereby improving the shooting quality of the camera module 100. In the embodiment where the first liquid lens 421 or the second liquid lens 423 can filter infrared light, the filter 700 can be omitted, so as to simplify the structure of the camera module 100 and reduce the cost of the camera module 100.

Referring to fig. 3 and 4, in some embodiments, the first liquid lens 421 and the second liquid lens 423 are both oil type lenses. The oil liquid type lens comprises two mutually incompatible and non-wetting conductive liquids and insulating liquids which are positioned in a closed containing cavity, and an interface is formed between the conductive liquids and the insulating liquids. The conductive liquid and the insulating liquid are transparent liquids to avoid affecting light incidence and image formation. Further, the refractive indices of the conducting liquid and the insulating liquid are similar to reduce the reflection of the interfacial surface to incident light. The densities of the conductive liquid and the insulating liquid are close to each other so that the interface can be free from the influence of gravity and the oil type lens has a stable optical axis. The conductive liquid is a conductive aqueous solution, such as saline solution, sodium sulfate solution, and the like, and the insulating liquid is a non-polar liquid, such as silicone oil solution, bromododecane solution, and the like. Under the action of an external electric field, the shape of the interface of the conductive liquid and the insulating liquid can be changed, and then the focal length of the oil liquid lens is changed. For example, the housing of the oil type lens may be provided with electrodes to form an electric field within the enclosed volume. Because adopt the electric field to exert the effect to fluid type lens, consequently fluid type lens can have relatively less volume to need not to set up the focus of other actuating mechanism in order to adjust fluid type lens, consequently can simplify camera module 100's structure, be favorable to camera module 100's miniaturized design, and easily realize focusing and anti-shake function, and can obtain faster response speed, and then promote the experience of shooing. For the image sensor 500 with high pixels, since it is not necessary to adopt other driving mechanisms to realize focusing and anti-shake functions, the structure of the camera module 100 can be simplified, and the miniaturization design of the camera module 100 is facilitated.

With reference to fig. 5 and 6, since the camera module 100 includes the first liquid lens 421 and the second liquid lens 423, the volume of the first liquid lens 421 or the second liquid lens 423 can be relatively small, and after the first liquid lens 421 and the second liquid lens 423 are combined, a larger refraction angle range can be obtained, so as to improve the shooting performance of the camera module 100. Compared with a single liquid lens with a large volume, the volumes of the first liquid lens 421 and the second liquid lens 423 are relatively small, the liquid is easier to drive to deform, higher control precision can be obtained, and therefore shooting performance of the camera module 100 can be improved. It is understood that the camera module 100 may include more than three liquid lenses.

Referring to fig. 7 and 8, in other embodiments, the first liquid lens 421 and the second liquid lens 423 are both compression type lenses. The extrusion type lens comprises liquid positioned in the closed cavity, the liquid is coated by the flexible film, and the liquid and the flexible film are transparent so as to reduce the influence on light. The shape of the light-emitting surface of the extrusion type lens can be changed by applying extrusion force to the flexible film from the outside, and further the focal length of the extrusion type lens is changed. In such an embodiment, a magnetostrictive film, a piezoelectric material, or a solenoid structure may be used to apply a compressive force to the flexible film to deform the flexible film. The magnetostrictive material can deform under the action of a magnetic field, the piezoelectric material can deform under the action of an electric field, and the magnet coil structure is a structure which uses a magnet to generate the magnetic field and drives an electrified coil to move in the magnetic field so as to apply extrusion force. The above structures can apply a pressing force to the flexible film to drive the liquid to flow and deform. The mode of increasing the voltage or current to increase the driving force is easy to realize, and the deformation of the liquid is relatively easy to realize, so that the embodiment can also realize the focusing and anti-shaking functions of the camera module 100, and can simplify the structure of the camera module 100, so as to be beneficial to the miniaturization design of the camera module 100. Of course, in another embodiment, one of the first liquid lens 421 and the second liquid lens 423 is an oil type lens, and the other is a squeeze type lens. The camera module 100 with the structure can also obtain higher focusing and anti-shaking performances, has higher corresponding speed, and is favorable for the miniaturization design of the camera module 100.

Above-mentioned camera module 100, because lens structure 400 includes lens group 410 and first liquid lens 421, second liquid lens 423, first liquid lens 421, second liquid lens 423 include the liquid that can pass through respectively, and the deformation of liquid is easily controlled to the required structure occupation space of control is less, easily realizes. Through control liquid deformation, change the angle of emergent ray, can realize focusing or anti-shake function, consequently foretell structure can satisfy focusing or anti-shake requirement of high pixel camera module 100 to be favorable to camera module 100's miniaturized design. Because first liquid lens 421, second liquid lens 423 can control respectively to can realize comparatively accurate control to the angle of emergent ray, and more than two liquid lens can obtain great refraction angle scope, with the shooting performance that promotes camera module 100.

Referring to fig. 2, in some embodiments, the light incident surface of the camera module 100 is perpendicular to the optical axis 411, that is, light incident along the direction extending from the optical axis 411 of the lens group 410 can be directly incident on the lens structure 400. When the camera module 100 with such a structure is used as a front camera or a rear camera, the extending direction of the optical axis 411 of the lens group 410 is parallel to the thickness direction of the terminal device 10, or a small inclination angle can be provided to meet the requirement of processing error.

Referring to fig. 9, in another embodiment, the camera module 100 includes a reflection unit 800, the reflection unit 800 is connected to the base 300, and the ambient light can be incident on the reflection unit 800 and reflected by the reflection unit 800 to the lens structure 400. In this embodiment, the light incident surface of the camera module 100 may be perpendicular to or inclined with respect to the optical axis 411 of the lens group 410. When the camera module 100 with such a structure is applied to the terminal device 10, the optical axis 411 of the lens group 410 may be disposed perpendicular to the thickness direction of the terminal device 10, for example, the optical axis 411 of the lens group 410 may extend along the length or width direction of the terminal device 10, or may form an angle with the length direction of the terminal device 10. In the camera module 100 with such a structure, the extending direction of the optical axis 411 of the lens group 410 may have a relatively large length, so as to arrange more lenses, thereby improving the shooting performance of the camera module 100. For example, the camera module 100 with such a structure can have a strong optical zoom performance to improve the shooting performance of the camera module 100.

The reflection unit 800 may be a reflection prism. Further, the reflection prism has a reflection surface 810, and the reflection surface 810 can generate total reflection to the light incident to the reflection surface 810, so as to reduce the loss of the incident light and improve the shooting quality of the camera module 100. In other embodiments, the reflection unit 800 includes a prism and a reflection film disposed on a surface of the prism, and the ambient light is incident to the reflection film from the prism and reflected by the reflection film to the lens structure 400. The reflective film may be a total reflection film, which reduces the loss of incident light and improves the shooting performance of the camera module 100. And in such embodiments, the provision of the reflective film may reduce the requirements for the prism to save on the cost of the optical device.

Referring to fig. 10, in the second embodiment of the present application, a first liquid lens 421 and a second liquid lens 423 are adjacently disposed, and a lens group 410, the first liquid lens 421, the second liquid lens 423, and an image sensor 500 are sequentially disposed from an object side to an image side along an optical axis 411. The lens group 410 includes one or more than two lenses, the lenses in the lens group 410 are made of resin or glass or other materials, and the lenses in the lens group 410 have fixed shapes and structures.

Referring to fig. 3 and 4, in some embodiments, the first liquid lens 421 and the second liquid lens 423 are both oil type lenses. The oil liquid type lens comprises two mutually incompatible and non-wetting conductive liquids and insulating liquids which are positioned in a closed containing cavity, and an interface is formed between the conductive liquids and the insulating liquids. The conductive liquid and the insulating liquid are transparent liquids to avoid affecting light incidence and image formation. Further, the refractive indices of the conducting liquid and the insulating liquid are similar to reduce the reflection of the interfacial surface to incident light. The conducting and insulating liquids are close in density so that the interface is free from gravity and the oil type lens has a stable optical axis 411. The conductive liquid is a conductive aqueous solution, such as saline solution, sodium sulfate solution, and the like, and the insulating liquid is a non-polar liquid, such as silicone oil solution, bromododecane solution, and the like. Under the action of an external electric field, the shape of the interface of the conductive liquid and the insulating liquid can be changed, and then the focal length of the oil liquid lens is changed. For example, the housing of the oil type lens may be provided with electrodes to form an electric field within the enclosed volume. Because adopt the electric field to exert the effect to fluid type lens, consequently fluid type lens can have relatively less volume to need not to set up the focus of other actuating mechanism in order to adjust fluid type lens, consequently can simplify camera module 100's structure, be favorable to camera module 100's miniaturized design, and easily realize focusing and anti-shake function, and can obtain faster response speed, and then promote the experience of shooing. For the image sensor 500 with high pixels, since it is not necessary to adopt other driving mechanisms to realize focusing and anti-shake functions, the structure of the camera module 100 can be simplified, and the miniaturization design of the camera module 100 is facilitated.

In other embodiments, with reference to fig. 7 and 8, the first liquid lens 421 and the second liquid lens 423 are both squeeze lenses. The extrusion type lens comprises liquid positioned in the closed cavity, the liquid is coated by the flexible film, and the liquid and the flexible film are transparent so as to reduce the influence on light. The shape of the light-emitting surface of the extrusion type lens can be changed by applying extrusion force to the flexible film from the outside, and further the focal length of the extrusion type lens is changed. In such an embodiment, a magnetostrictive film, a piezoelectric material, or a solenoid structure may be used to apply a compressive force to the flexible film to deform the flexible film. The mode of increasing the voltage or current to increase the driving force is easy to realize, and the deformation of the liquid is relatively easy to realize, so that the embodiment can also realize the focusing and anti-shaking functions of the camera module 100, and can simplify the structure of the camera module 100, so as to be beneficial to the miniaturization design of the camera module 100. Of course, in another embodiment, one of the first liquid lens 421 and the second liquid lens 423 is an oil type lens, and the other is a squeeze type lens. The camera module 100 with the structure can also obtain higher focusing and anti-shaking performances, has higher corresponding speed, and is favorable for the miniaturization design of the camera module 100.

In some embodiments, the light incident surface of the camera module 100 is perpendicular to the optical axis 411, that is, light incident along the direction extending from the optical axis 411 of the lens assembly 410 can be directly incident on the lens structure 400. When the camera module 100 with such a structure is used as a front camera or a rear camera, the extending direction of the optical axis 411 of the lens group 410 is parallel to the thickness direction of the terminal device 10, or a small inclination angle can be provided to meet the requirement of processing error.

Referring to fig. 11, in another embodiment, the camera module 100 includes a reflection unit 800, the reflection unit 800 is connected to the base 300, and the ambient light can be incident on the reflection unit 800 and reflected by the reflection unit 800 to the lens structure 400. In this embodiment, the light incident surface of the camera module 100 may be perpendicular to or inclined with respect to the optical axis 411 of the lens group 410. When the camera module 100 with such a structure is applied to the terminal device 10, the optical axis 411 of the lens group 410 may be disposed perpendicular to the thickness direction of the terminal device 10, for example, the optical axis 411 of the lens group 410 may extend along the length or width direction of the terminal device 10, or may form an angle with the length direction of the terminal device 10. In the camera module 100 with such a structure, the extending direction of the optical axis 411 of the lens group 410 may have a relatively large length, so as to arrange more lenses, thereby improving the shooting performance of the camera module 100. For example, the camera module 100 with such a structure can have a strong optical zoom performance to improve the shooting performance of the camera module 100.

In the second embodiment of the present application, other structures of the camera module 100 can refer to the first embodiment, and are not described herein again.
