Description

Technical Field

[0001] The present application relates to the field of optical imaging technology, and in particular to a liquid lens assembly, a camera module and an electronic device. Background Art

[0002] In order to meet people's demand for miniaturization of camera modules, liquid lens components with variable curvature and shape are used in camera modules to help the camera modules achieve anti-shake and focusing functions.

[0003] Specifically, in related technologies, a camera module includes a drive device and a liquid lens assembly, which includes a liquid lens. The drive device is connected to the liquid lens to drive the liquid lens to change its shape, thereby enabling the camera module to achieve anti-shake and focus functions through the liquid lens.

[0004] However, since the anti-shake function and the focus function are both achieved through the same liquid lens, blurred images will occur, resulting in poor image quality of the camera module. Summary of the Invention

[0005] The present application discloses a liquid lens assembly, a camera module and an electronic device, which can solve the problems of blurred imaging and poor imaging quality.

[0006] In order to achieve the above objectives, the present application discloses, on the one hand, a liquid lens assembly, comprising:

[0007] Liquid anti-shake lens;

[0008] The liquid focusing lens and the liquid anti-shake lens are stacked and connected to each other.

[0009] Since the liquid lens assembly includes a liquid anti-shake lens and a liquid focus lens, the liquid lens assembly can achieve the anti-shake function through the liquid anti-shake lens and the focus function through the liquid focus lens. That is, for the liquid lens assembly, the anti-shake function and the focus function are achieved through different liquid lenses. This is different from the related art, where the anti-shake function and the focus function are achieved through the same liquid lens. This can avoid the problems of blurred imaging and poor image quality when the liquid lens assembly is used in the camera module.

[0010] In addition, since the anti-shake function and the focus function are realized by different liquid lenses, the anti-shake function and the focus function can be made independent of each other, avoiding the mutual influence of the anti-shake function and the focus function, making the performance of the liquid lens assembly better.

[0011] In addition, since the liquid focusing lens and the liquid anti-shake lens are stacked and interconnected, the liquid focusing lens and the liquid anti-shake lens can form an integrated structure, which can make the structure of the entire liquid lens assembly compact and small.

[0012] Optionally, the liquid anti-shake lens comprises: an anti-shake film and an anti-shake liquid, the anti-shake film encloses an anti-shake cavity, and the anti-shake liquid is filled in the anti-shake cavity;

[0013] The liquid focusing lens comprises: a focusing film and a focusing liquid, wherein the focusing film encloses a focusing cavity, and the focusing liquid is filled in the focusing cavity;

[0014] The liquid lens assembly further includes a common transparent plate, and the liquid anti-shake lens and the liquid focusing lens are respectively connected to two sides of the common transparent plate.

[0015] By connecting the liquid anti-shake lens and the liquid focus lens to the two sides of the common transparent plate 3 respectively, the common transparent plate can be used as the transparent plate in the liquid anti-shake lens and also as the transparent plate in the liquid focus lens. That is, the common transparent plate is used by both the liquid anti-shake lens and the liquid focus lens. In this way, there is no need to provide separate transparent plates for the liquid anti-shake lens and the liquid focus lens, thereby making the liquid lens assembly lighter and thinner.

[0016] Optionally, the liquid anti-shake lens further includes an anti-shake transparent plate, and the anti-shake transparent plate is arranged on a side of the anti-shake film away from the common transparent plate.

[0017] By arranging an anti-shake transparent plate on the side of the anti-shake film away from the common transparent plate, when the liquid lens assembly is used in a camera module, the anti-shake transparent plate can be used to connect to a driving device in the camera module. In this way, the driving device can drive the anti-shake transparent plate to move, causing the position of the anti-shake transparent plate to change. After the position of the anti-shake transparent plate changes, the anti-shake transparent plate can drive the anti-shake film to move, and then the shape of the entire liquid anti-shake lens can be changed, thereby achieving the purpose of anti-shake.

[0018] When the liquid anti-shake lens includes a transparent anti-shake plate, since the transparent anti-shake plate can be connected to the anti-shake film over a large area, a slight change in the position of the transparent anti-shake plate can cause a significant change in the shape of the entire liquid anti-shake lens, thereby improving the anti-shake performance.

[0019] On the other hand, the present application discloses a camera module, comprising:

[0020] A driving device, comprising an anti-shake component, a focus component, and a support component;

[0021] The liquid lens assembly described in any one of the above aspects, wherein the liquid lens assembly has an optical axis, the common transparent plate is fixedly arranged on the supporting assembly, the anti-shake assembly is connected to the liquid anti-shake lens, and the focusing assembly is connected to the liquid focusing lens. The anti-shake assembly is used to change the inclination angle of the liquid anti-shake lens for anti-shake, and the focusing assembly is used to change the curvature of the liquid focusing lens for focusing.

[0022] By driving the movement of the liquid anti-shake lens through the anti-shake component, the camera module can realize the anti-shake function, and by driving the liquid focus lens through the focus component, the camera module can realize the focus function. That is, the anti-shake function and the focus function of the camera module are realized by different liquid lenses (i.e., liquid anti-shake lens and liquid focus lens). In this way, the problem of poor imaging quality of the camera module caused by realizing the anti-shake function and the focus function at the same time by the same liquid lens in the related technology can be avoided.

[0023] At the same time, since the anti-shake function and the focus function are realized through different liquid lenses, the anti-shake function and the focus function can be made independent of each other, thereby avoiding the mutual influence of the anti-shake function and the focus function, making the performance of the camera module better.

[0024] Optionally, the camera module further includes a support ring, the common transparent plate is connected to the support ring, and the support ring is fixedly arranged on the support assembly.

[0025] Since the liquid anti-shake lens and the liquid focus lens are respectively connected to both sides of the common transparent plate, the common transparent plate is connected to the support ring, and the support ring is fixed on the support assembly, the liquid anti-shake lens and the liquid focus lens are fixed to the support assembly through the common transparent plate and the support ring. In this way, the liquid anti-shake lens and the liquid focus lens can be jointly protected by the common transparent plate and the support ring, avoiding damage to the liquid anti-shake lens and the liquid focus lens during the process of directly fixing them to the support assembly.

[0026] In addition, since the common transparent plate is fixed on the supporting assembly via the supporting ring, the supporting ring can support the common transparent plate, thereby preventing the common transparent plate from being damaged.

[0027] Optionally, the support assembly is provided with a plurality of positioning portions extending along the optical axis toward the side close to the common transparent plate, and the plurality of positioning portions enclose a positioning cavity, the support ring is accommodated in the positioning cavity and the outer ring wall of the support ring is in contact with a side of the positioning portion close to the optical axis.

[0028] By accommodating the support ring in the positioning cavity and having the outer ring wall of the support ring fit against a side of the positioning portion close to the optical axis, the positioning portion can position the support ring, thereby achieving higher assembly accuracy when assembling the support ring to the support assembly.

[0029] Optionally, a first identification portion is provided at intervals on the outer edge of the support ring, and a second identification portion matching the first identification portion is provided on the common transparent plate. When the first identification portion is aligned with the second identification portion, the axis of the support ring is collinear with the axis of the common transparent plate.

[0030] Since the axis of the support ring is collinear with the axis of the common transparent plate when the first identification part is aligned with the second identification part, when the support ring is assembled to the common transparent plate, the axis of the support ring can be made collinear with the axis of the common transparent plate by aligning the first identification part with the second identification part. In this way, the assembly accuracy of the support ring when assembled to the common transparent plate can be higher, thereby making the assembly accuracy of the entire camera module higher.

[0031] Optionally, the first identification portion is a plurality of first protrusions spaced apart along the outer edge of the support ring, and the distance between a surface of the plurality of first protrusions away from the axis of the support ring and the axis of the support ring is a first distance;

[0032] The second identification portion is a plurality of second protrusions arranged at intervals along the outer edge of the common transparent plate, and the distance between the side of the plurality of second protrusions away from the axis of the common transparent plate and the axis of the common transparent plate is a second distance. The second protrusions correspond one-to-one to the first protrusions, and the first distance is equal to the second distance.

[0033] Because the second protrusions correspond one-to-one with the first protrusions, and the first distance between the side of the first protrusion facing away from the axis of the support ring and the axis of the support ring is equal to the second distance between the side of the second protrusion facing away from the axis of the common transparent plate and the axis of the common transparent plate, when the first protrusions are aligned with the second protrusions, the axis of the support ring and the axis of the common transparent plate are collinear. This method of achieving collinearity between the axis of the support ring and the axis of the common transparent plate is very simple, thereby reducing the manufacturing costs of the first and second identification components to a certain extent.

[0034] Optionally, the anti-shake component includes:

[0035] a connecting plate connected to a side of the liquid anti-shake lens away from the common transparent plate;

[0036] a plurality of legs, the plurality of legs extending from an outer edge of the connecting plate toward a side close to the common transparent plate, the plurality of legs being covered on the periphery of the support ring, and the plurality of legs being spaced apart to form gaps between adjacent legs, the first identification portion corresponding to a position of the gap;

[0037] An anti-shake driving unit is connected to the legs and is used to drive the legs to move, thereby driving the connecting plate to move, so as to change the tilt angle of the liquid anti-shake lens.

[0038] Because the multiple leg covers are positioned around the periphery of the support ring and the multiple legs are spaced apart, gaps are formed between adjacent legs, and the first recognition portion is positioned correspondingly to the gaps. This prevents interference between the legs and the first recognition portion, facilitating glue application between the first and second recognition portions and simplifying assembly of the entire camera module.

[0039] Optionally, the support ring is located on a side of the common transparent plate away from the liquid anti-shake lens, the liquid focusing lens is connected to a side of the common transparent plate away from the liquid anti-shake lens, and the liquid focusing lens is located inside the support ring.

[0040] By connecting the liquid focus lens to the side of the common transparent plate away from the liquid anti-shake lens and locating the liquid focus lens within the support ring, the support ring can surround at least part of the structure of the liquid focus lens within its own ring. In this way, the support ring can protect the liquid focus lens to a certain extent, thereby extending the service life of the liquid focus lens.

[0041] Optionally, the thickness of the support ring is less than or equal to the thickness of the liquid focus lens.

[0042] By making the thickness of the support ring less than or equal to the thickness of the liquid focus lens, the support ring can use the thickness space of the liquid focus lens to accommodate its own structure. In this way, the support ring will not affect the overall thickness of the liquid lens assembly, thereby making the entire camera module more compact.

[0043] Optionally, the focusing component includes:

[0044] a focus ring connected to a side of the liquid focus lens away from the common transparent plate;

[0045] A focus driving unit is connected to the focus ring and is used to drive the focus ring to move so as to change the curvature of the liquid focus lens.

[0046] Because the focus ring is annular, as the focus ring gradually squeezes the liquid focus lens, the curvature of the liquid focus lens at the position corresponding to the center cavity of the focus ring will change. It is understandable that when the focus ring is annular, the liquid focus lens can be squeezed along the entire circumference of the focus ring, thereby making the curvature of the liquid focus lens change more uniformly. Based on this, when the curvature of the liquid focus lens is changed by the focus ring, the curvature of the liquid focus lens can be made more uniform, thereby improving the focusing performance of the camera module.

[0047] Optionally, the connecting plate has a first light hole, the focus ring has a second light hole, the axis of the first light hole coincides with the axis of the second light hole, and the diameter of the first light hole is larger than the diameter of the second light hole.

[0048] By making the axis of the first light hole coincide with the axis of the second light hole and the diameter of the first light hole being larger than the diameter of the second light hole, the occurrence of afterimages can be avoided, thereby improving the performance of the camera module.

[0049] Optionally, a plurality of first focus limiting portions are provided on the outer edge of the focus ring;

[0050] The focusing assembly further includes a focus movable portion, wherein a plurality of second focus limit portions are provided on the focus movable portion at positions corresponding to the plurality of first focus limit portions, the plurality of first focus limit portions correspond one-to-one with the plurality of second focus limit portions, and when the first focus limit portions match the second focus limit portions, the axis of the focus movable portion and the axis of the focus ring both coincide with the optical axis;

[0051] The focus ring is connected to the focus movable part, the focus movable part is connected to the focus driving part, and the focus driving part is used to drive the focus movable part to move, thereby driving the focus ring to move.

[0052] Since a plurality of first focus limit parts are provided on the outer edge of the focus ring, a plurality of second focus limit parts are provided at positions of the focus movable part corresponding to the plurality of first focus limit parts, the plurality of first focus limit parts correspond one to one with the plurality of second focus limit parts, and when the first focus limit parts match the second focus limit parts, the axis of the focus movable part and the axis of the focus ring both coincide with the optical axis. Therefore, when the focus ring is assembled onto the focus movable part, the assembly accuracy between the focus ring and the focus movable part can be made higher under the limiting action of the first focus limit part and the second focus limit part.

[0053] On another aspect, the present application discloses an electronic device, which includes the camera module described in any one of the other aspects above.

[0054] Because the camera module's stabilization and focus functions are implemented using different liquid lenses, poor image quality can be avoided. Furthermore, the stabilization and focus functions can be made independent of each other, preventing them from interfering with each other and improving the performance of the camera module. Consequently, electronic devices including camera modules can achieve even better image quality.

[0055] Compared with the prior art, the present invention has the following advantages:

[0056] Since the liquid lens assembly includes a liquid anti-shake lens and a liquid focus lens, the liquid lens assembly can achieve the anti-shake function through the liquid anti-shake lens and the focus function through the liquid focus lens. That is, for the liquid lens assembly, the anti-shake function and the focus function are achieved through different liquid lenses. This is different from the related art, where the anti-shake function and the focus function are achieved through the same liquid lens. This can avoid the problems of blurred imaging and poor image quality when the liquid lens assembly is used in the camera module.

[0057] In addition, since the anti-shake function and the focus function are realized by different liquid lenses, the anti-shake function and the focus function can be made independent of each other, avoiding the mutual influence of the anti-shake function and the focus function, making the performance of the liquid lens assembly better.

[0058] In addition, since the liquid focusing lens and the liquid anti-shake lens are stacked and interconnected, the liquid focusing lens and the liquid anti-shake lens can form an integrated structure, which can make the structure of the entire liquid lens assembly compact and small.

[0080] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0082] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location.

[0085] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0086] Figure 1A This is a schematic diagram of the structure of a liquid lens assembly provided by an embodiment of the present application. Figure 1A The liquid lens assembly includes a liquid anti-shake lens 1 and a liquid focus lens 2. The liquid focus lens 2 and the liquid anti-shake lens 1 are stacked and connected to each other.

[0087] In the embodiment of the present application, since the liquid lens assembly includes a liquid anti-shake lens 1 and a liquid focus lens 2, the liquid lens assembly can achieve an anti-shake function through the liquid anti-shake lens 1 and achieve a focusing function through the liquid focus lens 2. In other words, for the liquid lens assembly, the anti-shake function and the focusing function are achieved through different liquid lenses. This is different from the related art, in which the anti-shake function and the focusing function are both achieved through the same liquid lens. This can avoid the problems of blurred imaging and poor image quality when the liquid lens assembly is used in a camera module.

[0088] In addition, since the anti-shake function and the focus function are realized by different liquid lenses, the anti-shake function and the focus function can be made independent of each other, avoiding the mutual influence of the anti-shake function and the focus function, making the performance of the liquid lens assembly better.

[0089] In addition, since the liquid focusing lens 2 and the liquid anti-shake lens 1 are stacked and interconnected, the liquid focusing lens 2 and the liquid anti-shake lens 1 can form an integrated structure, so that the structure of the entire liquid lens assembly can be compact and small.

[0090] The liquid focus lens 2 and the liquid anti-shake lens 1 can be connected to each other by gluing, or by other means, which is not limited in the embodiment of the present application.

[0091] It is worth noting that the above-mentioned focus can be understood as focus in a general sense, or as macro (micro-adjustment of focal length).

[0092] In some embodiments, see Figure 1B and Figure 2 The liquid anti-shake lens 1 includes an anti-shake film 11 and an anti-shake liquid 12 (not shown in the figure). The anti-shake film 11 encloses an anti-shake cavity 10, and the anti-shake liquid 12 fills the anti-shake cavity 10. The liquid focus lens 2 includes a focus film 21 and a focus liquid 22 (not shown in the figure). The focus film 21 encloses a focus cavity 20, and the focus liquid 22 fills the focus cavity 20. The liquid lens assembly also includes a common transparent plate 3. The liquid anti-shake lens 1 and the liquid focus lens 2 are respectively connected to the two sides of the common transparent plate 3.

[0093] In the case of the liquid anti-shake lens 1, since the anti-shake film 11 encloses the anti-shake cavity 10 and the anti-shake liquid 12 fills the anti-shake cavity 10, when the liquid anti-shake lens 1 is subjected to external forces, both the anti-shake film 11 and the anti-shake liquid 12 contained within the film 11 can deform. This can change the angle and position of light passing through the liquid anti-shake lens 1, thereby achieving the anti-shake function. By enclosing the anti-shake liquid 12 within the anti-shake film 11, the liquid anti-shake lens 1 can deform when subjected to external forces, thereby enabling the liquid anti-shake lens 1 to achieve the anti-shake function. This ingenious design concept and compact structure make the entire liquid anti-shake lens 1 compact.

[0094] The anti-shake film 11 can be an elastic, transparent film capable of arbitrary deformation. In one possible implementation, the anti-shake film 11 can be a PDMS (Polydimethylsiloxane) film, which is not limited in this embodiment of the present application. Because PDMS films have excellent optical and mechanical properties, using a PDMS film as the anti-shake film 11 can improve the performance of the liquid anti-shake lens 1.

[0095] The above-mentioned anti-shake liquid 12 can be an optical liquid. When selecting the optical liquid, on the premise that the optical liquid will not have a negative effect (such as a chemical reaction) with the anti-shake film 11, any required optical liquid with a specific refractive index and dispersion characteristics can be selected as needed. The embodiment of the present application does not limit the anti-shake liquid 12.

[0096] Similarly, for the liquid focus lens 2, since the focus film 21 encloses the focus cavity 20 and the focus liquid 22 is filled in the focus cavity 20, when the liquid focus lens 2 is subjected to an external force, the focus film 21 and the focus liquid 22 wrapped in the focus film 21 can both deform. This can change the exit angle and position of light passing through the liquid focus lens 2, thereby achieving the focusing function. By enclosing the focus liquid 22 in the focus film 21, the liquid focus lens 2 can be deformed when subjected to an external force, thereby enabling the liquid focus lens 2 to achieve the focusing function. The design is ingenious and the structure is compact, thus making the entire liquid focus lens 2 compact.

[0097] The focusing film 21 can be the same as the anti-shake film 11, and the embodiment of the present application will not be described in detail here. The focusing liquid 22 can also be the same as the anti-shake liquid 12, and the embodiment of the present application will not be described in detail here.

[0098] By connecting the liquid anti-shake lens 1 and the liquid focus lens 2 to the two sides of the common transparent plate 3, the common transparent plate 3 can be used as the transparent plate in the liquid anti-shake lens 1 and the transparent plate in the liquid focus lens 2. That is, the common transparent plate 3 is used by both the liquid anti-shake lens 1 and the liquid focus lens 2. In this way, there is no need to provide separate transparent plates for the liquid anti-shake lens 1 and the liquid focus lens 2, thereby making the liquid lens assembly lighter and thinner.

[0099] In addition, because the liquid anti-shake lens 1 and the liquid focus lens 2 are both very easily deformed, the liquid lens assembly consisting of the liquid anti-shake lens 1 and the liquid focus lens 2 is loose and soft, making it difficult to assemble with other components. Based on this, by connecting the liquid anti-shake lens 1 and the liquid focus lens 2 to both sides of the common transparent plate 3, the common transparent plate 3 can support the liquid anti-shake lens 1 and the liquid focus lens 2. In this way, the entire liquid lens assembly can be prevented from being loose and soft, thereby making the assembly of the entire liquid lens assembly with other components convenient and easy.

[0100] It should be noted that the material of the common transparent plate 3 can be glass, or resin, etc., and the embodiment of the present application does not limit the material of the common transparent plate 3.

[0101] In some embodiments, see Figure 3 and Figure 4The liquid anti-shake lens 1 further includes an anti-shake transparent plate 13, which is disposed on a side away from the anti-shake film 11. By disposing the anti-shake transparent plate 13 on a side of the anti-shake film 11 away from the common transparent plate 3, when the liquid lens assembly is used in a camera module, the anti-shake transparent plate 13 can be connected to a driving device in the camera module. In this way, the driving device can drive the anti-shake transparent plate 13 to move, causing the position of the anti-shake transparent plate 13 to change. After the position of the anti-shake transparent plate 13 changes, the anti-shake transparent plate 13 can move the anti-shake film 11, thereby changing the shape of the entire liquid anti-shake lens 1, thereby achieving the purpose of anti-shake.

[0102] When the liquid anti-shake lens 1 includes the anti-shake transparent plate 13, since the anti-shake transparent plate 13 can be connected to the anti-shake film 11 over a large area, a slight change in the position of the anti-shake transparent plate 13 can cause a significant change in the shape of the entire liquid anti-shake lens 1, thereby improving the anti-shake performance.

[0103] In addition, since the anti-shake transparent plate 13 is connected to the anti-shake film 11 over a large area, when the anti-shake transparent plate 13 moves, the large area of ​​the anti-shake film 11 can be driven to move along with the anti-shake transparent plate 13, thereby making the deformation of the entire liquid anti-shake lens 1 at various positions more uniform, thereby achieving better anti-shake performance.

[0104] In summary, in the embodiment of the present application, since the liquid lens assembly includes a liquid anti-shake lens 1 and a liquid focus lens 2, the liquid lens assembly can achieve an anti-shake function through the liquid anti-shake lens 1 and achieve a focusing function through the liquid focus lens 2. In other words, for the liquid lens assembly, the anti-shake function and the focusing function are achieved through different liquid lenses. This is different from the related art, in which the anti-shake function and the focusing function are both achieved through the same liquid lens. This can avoid the problems of blurred imaging and poor image quality when the liquid lens assembly is used in a camera module.

[0105] In addition, since the anti-shake function and the focus function are realized by different liquid lenses, the anti-shake function and the focus function can be made independent of each other, avoiding the mutual influence of the anti-shake function and the focus function, making the performance of the liquid lens assembly better.

[0106] In addition, since the liquid focusing lens 2 and the liquid anti-shake lens 1 are stacked and interconnected, the liquid focusing lens 2 and the liquid anti-shake lens 1 can form an integrated structure, so that the structure of the entire liquid lens assembly can be compact and small.

[0107] Furthermore, by connecting the liquid anti-shake lens 1 and the liquid focus lens 2 to the two sides of the common transparent plate 3, on the one hand, the common transparent plate 3 can be used as the transparent plate in the liquid anti-shake lens 1, and can also be used as the transparent plate in the liquid focus lens 2. That is, the common transparent plate 3 is used by the liquid anti-shake lens 1 and the liquid focus lens 2. In this way, there is no need to provide separate transparent plates for the liquid anti-shake lens 1 and the liquid focus lens 2, thereby making the liquid lens assembly lighter and thinner.

[0108] Figure 5 is a structural diagram of a camera module provided in an embodiment of the present application, Figure 6 yes Figure 5 Cross-sectional view of the camera module at the AA position.

[0109] See also Figure 5 and Figure 6 The camera module includes a drive device 100 and a liquid lens assembly 200. The liquid lens assembly 200 has an optical axis Z. The drive device 100 includes an anti-shake assembly 101, a focusing assembly 102, and a support assembly 103. A common transparent plate 3 is fixedly mounted on the support assembly 103. The anti-shake assembly 101 is connected to the liquid anti-shake lens 1, and the focusing assembly 102 is connected to the liquid focus lens 2. The anti-shake assembly 101 is used to change the tilt angle of the liquid anti-shake lens 1 to achieve anti-shake, and the focusing assembly 102 is used to change the curvature of the liquid focus lens 2 to achieve focus.

[0110] The liquid lens assembly 200 may have the same structure as the liquid lens assembly 200 in the above embodiment and may bring the same or similar beneficial effects, which will not be described in detail here.

[0111] In the embodiment of the present application, since the common transparent plate 3 is fixedly set on the support component 103, the liquid anti-shake lens 1 is set on the common transparent plate 3, and the anti-shake component 101 of the driving device 100 is connected to the liquid anti-shake lens 1, therefore, when the anti-shake component 101 moves, it can drive part of the structure of the liquid anti-shake lens 1 to move relative to the support component 103, so that the inclination angle of the liquid anti-shake lens 1 relative to the support component 103 can be changed. After the inclination angle of the liquid anti-shake lens 1 changes, the angle and position of the outgoing light emitted from the liquid anti-shake lens 1 to the camera module can be changed, thereby realizing the anti-shake function.

[0112] Since the liquid focus lens 2 is arranged on the common transparent plate 3, the focus component 102 of the driving device 100 is connected to the liquid focus lens 2. Therefore, when the focus component 102 moves, it can drive part of the structure of the liquid focus lens 2 to move relative to the support component 103, so that the curvature of the liquid focus lens 2 can be changed. After the curvature of the liquid focus lens 2 changes, the position of the output light from the liquid focus lens 2 to the camera module can be changed, thereby realizing the focusing function.

[0113] It can be seen that by driving the liquid anti-shake lens 1 to move through the anti-shake component 101, the camera module can realize the anti-shake function, and by driving the liquid focus lens 2 to move through the focusing component 102, the camera module can realize the focus function. That is, the anti-shake function and the focus function of the camera module are realized by different liquid lenses (i.e., liquid anti-shake lens 1 and liquid focus lens 2). In this way, the problem of poor imaging quality of the camera module caused by realizing the anti-shake function and the focus function at the same time by the same liquid lens in the related technology can be avoided.

[0114] At the same time, since the anti-shake function and the focus function are realized through different liquid lenses, the anti-shake function and the focus function can be made independent of each other, thereby avoiding the mutual influence of the anti-shake function and the focus function, making the performance of the camera module better.

[0115] In some embodiments, see Figure 5 and Figure 6 The camera module also includes a support ring 300 , the common transparent plate 3 is connected to the support ring 300 , and the support ring 300 is fixedly set on the support assembly 103 .

[0116] Since the support ring 300 is fixedly set on the support assembly 103 and the common transparent plate 3 is connected to the support ring 300, the liquid anti-shake lens 1 and the liquid focus lens 2 are fixedly set on the support assembly 103 through the common transparent plate 3 and the support ring 300. In this way, the liquid anti-shake lens 1 and the liquid focus lens 2 can be jointly protected by the common transparent plate 3 and the support ring 300, avoiding damage to the liquid anti-shake lens 1 and the liquid focus lens 2 during the process of being directly fixed to the support assembly 103.

[0117] In addition, since the common transparent plate 3 is fixed on the supporting assembly 103 through the supporting ring 300 , the supporting ring 300 can support the common transparent plate 3 , thereby preventing the common transparent plate 3 from being damaged.

[0118] In some embodiments, see Figure 7A and Figure 7BThe support assembly 103 is provided with a plurality of positioning portions 1031 extending along the optical axis Z toward a side close to the common transparent plate 3 , and the plurality of positioning portions 1031 enclose a positioning cavity 1030 (ie: Figure 7B The support ring 300 is accommodated in the positioning cavity 1030, and the outer wall of the support ring 300 is in contact with the surface of the positioning portion 1031 that is close to the optical axis Z. By accommodating the support ring 300 in the positioning cavity 1030 and making the outer wall of the support ring 300 in contact with the surface of the positioning portion 1031 that is close to the optical axis Z, the positioning portion 1031 can position the support ring 300, thereby improving the assembly accuracy when the support ring 300 is assembled to the support assembly 103.

[0119] The positioning portion 1031 may be a protrusion extending in a direction close to the support ring 300 or other possible structures, which is not limited in this embodiment of the present application.

[0120] In addition, the number of the positioning portions 1031 may be 4 or any other number, which is not limited in the embodiment of the present application.

[0121] In some embodiments, see Figure 7A The outer edge of the support ring 300 is spaced apart with a first identification portion 301, and the common transparent plate 3 is provided with a second identification portion 31 matching the first identification portion 301. When the first identification portion 301 is aligned with the second identification portion 31, the axis of the support ring 300 is collinear with the axis of the common transparent plate 3.

[0122] Since when the first identification part 301 is aligned with the second identification part 31, the axis of the support ring 300 is collinear with the axis of the common transparent plate 3. Therefore, when the support ring 300 is assembled to the common transparent plate 3, the axis of the support ring 300 can be made collinear with the axis of the common transparent plate 3 by aligning the first identification part 301 with the second identification part 31. In this way, the assembly accuracy of the support ring 300 when assembled to the common transparent plate 3 can be higher, thereby making the assembly accuracy of the entire camera module higher.

[0123] Specifically, in some embodiments, see Figure 7A The first identification portion 301 comprises a plurality of first protrusions spaced apart along the outer edge of the support ring 300. The distance between the axis of the support ring 300 and the side of the plurality of first protrusions facing away from the axis of the support ring 300 is a first distance. The second identification portion 31 comprises a plurality of second protrusions spaced apart along the outer edge of the common transparent plate 3. The distance between the axis of the common transparent plate 3 and the side of the plurality of second protrusions facing away from the axis of the common transparent plate 3 is a second distance. The second protrusions correspond one-to-one with the first protrusions, and the first distance is equal to the second distance.

[0124] Because the second protrusions correspond one-to-one with the first protrusions, and the first distance between the side of the first protrusion facing away from the axis of support ring 300 and the axis of support ring 300 is equal to the second distance between the side of the second protrusion facing away from the axis of common transparent plate 3 and the axis of common transparent plate 3, when the first protrusions are aligned with the second protrusions, the axis of support ring 300 and the axis of common transparent plate 3 are collinear. This method of achieving collinearity between the axis of support ring 300 and the axis of common transparent plate 3 is very simple, thus reducing the manufacturing costs of first identification portion 301 and second identification portion 31 to a certain extent.

[0125] The number of first identification units 301 may be four or any other number, and the embodiment of the present application does not limit the number of first identification units 301. Similarly, the number of second identification units 31 may be four or any other number, and the embodiment of the present application does not limit the number of second identification units 31.

[0126] In some embodiments, see Figure 5 The anti-shake assembly 101 includes: a connecting plate 1011, multiple legs 1012, and an anti-shake drive unit 1013. The connecting plate 1011 is connected to the side of the liquid anti-shake lens 1 away from the common transparent plate 3. The multiple legs 1012 extend from the outer edge of the connecting plate 1011 toward the side close to the common transparent plate 3. The multiple legs 1012 are covered on the periphery of the support ring 300, and the multiple legs 1012 are arranged at intervals, forming gaps between adjacent legs 1012. The first identification unit 301 corresponds to the position of the gap. The anti-shake drive unit 1013 is connected to the legs 1012 and is used to drive the legs 1012 to move, thereby driving the connecting plate 1011 to move, so as to change the tilt angle of the liquid anti-shake lens 1.

[0127] In this embodiment, since the anti-shake drive unit 1013 is connected to the leg 1012, when the anti-shake drive unit 1013 moves, it can drive the leg 1012 to move. Since the leg 1012 is formed by extending from the outer edge of the connecting plate 1011, when the leg 1012 moves, it can drive the connecting plate 1011 to move. After the connecting plate 1011 moves, since the connecting plate 1011 is connected to the side of the liquid anti-shake lens 1 away from the shared transparent plate 3, when the connecting plate 1011 moves, the liquid anti-shake lens 1 can be deformed, thereby changing the tilt angle of the liquid anti-shake lens 1. After the tilt angle of the liquid anti-shake lens 1 changes, the camera module can achieve the anti-shake function.

[0128] Because the legs 1012 are arranged around the periphery of the support ring 300 and are spaced apart, gaps are formed between adjacent legs 1012, and the first identification portion 301 is positioned correspondingly to the gaps. This prevents interference between the legs 1012 and the first identification portion 301, facilitating the dispensing of glue between the first identification portion 301 and the second identification portion 31, making assembly of the entire camera module much simpler.

[0129] Among them, the number of legs 1012 can be 4, or other numbers, such as 2 or 3, etc. The embodiment of the present application does not limit the number of legs 1012.

[0130] In addition, the anti-shake driving unit 1013 is any structure that can drive the leg 1012 to move, and the embodiment of the present application does not limit the anti-shake driving unit 1013.

[0131] In some embodiments, see Figure 6 The support ring 300 is located on the side of the common transparent plate 3 away from the liquid anti-shake lens 1, the liquid focus lens 2 is connected to the side of the common transparent plate 3 away from the liquid anti-shake lens 1 and the liquid focus lens 2 is located in the support ring 300.

[0132] By connecting the liquid focus lens 2 to the side of the common transparent plate 3 away from the liquid anti-shake lens 1 and positioning the liquid focus lens 2 within the support ring 300, the support ring 300 can surround at least part of the structure of the liquid focus lens 2 within its own ring. In this way, the support ring 300 can protect the liquid focus lens 2 to a certain extent, thereby extending the service life of the liquid focus lens 2.

[0133] Further, in some embodiments, see Figure 6 The thickness of the support ring 300 is less than or equal to the thickness of the liquid focus lens 2. By making the thickness of the support ring 300 less than or equal to the thickness of the liquid focus lens 2, the support ring 300 can use the thickness of the liquid focus lens 2 to accommodate its own structure. In this way, the support ring 300 will not affect the overall thickness of the liquid lens assembly, thereby making the entire camera module more compact.

[0134] In some embodiments, see Figure 6 The focusing assembly 102 includes a focus ring 1021 and a focus drive unit 1022. The focus ring 1021 is connected to the side of the liquid focus lens 2 that is away from the shared transparent plate 3. The focus drive unit 1022 is connected to the focus ring 1021 and is used to drive the focus ring 1021 to change the curvature of the liquid focus lens 2.

[0135] In this embodiment, since the focus driving unit 1022 is connected to the focus ring 1021, when the focus driving unit 1022 moves, the focus ring 1021 can be driven to move. Since the focus ring 1021 is connected to the side of the liquid focus lens 2 away from the common transparent plate 3, when the focus ring 1021 moves, the focus ring 1021 can squeeze the liquid focus lens 2, so that the curvature of the liquid focus lens 2 changes, thereby realizing the focusing function.

[0136] Because the focus ring 1021 is annular, as the focus ring 1021 gradually squeezes the liquid focus lens 2, the curvature of the liquid focus lens 2 at the position corresponding to the central cavity of the focus ring 1021 will change. It is understood that when the focus ring 1021 is annular, the liquid focus lens 2 can be squeezed along the entire circumference of the focus ring 1021, thereby making the curvature of the liquid focus lens 2 change more uniformly. Based on this, when the curvature of the liquid focus lens 2 is changed by the focus ring 1021, the curvature of the liquid focus lens 2 can be made more uniform, thereby improving the focusing performance of the camera module.

[0137] It should be noted that the focus driving unit 1022 may be any structure capable of driving the focus ring 1021 to move, and the embodiment of the present application does not limit the focus driving unit 1022 .

[0138] In some embodiments, see Figure 5 and Figure 6 The connecting plate 1011 has a first light hole 1010, and the focus ring 1021 has a second light hole 1020. The axis of the first light hole 1010 coincides with the axis of the second light hole 1020, and the diameter of the first light hole 1010 is larger than the diameter of the second light hole.

[0139] By making the axis of the first light hole 1010 coincide with the axis of the second light hole 1020 and the diameter of the first light hole 1010 larger than the diameter of the second light hole, the occurrence of afterimages can be avoided, thereby improving the performance of the camera module.

[0140] In some embodiments, see Figure 8 and Figure 9The outer edge of the focus ring 1021 is provided with a plurality of first focus limit portions 10211. The focus assembly 102 also includes a focus movable portion 1023. The focus movable portion 1023 is provided with a plurality of second focus limit portions 10231 at positions corresponding to the plurality of first focus limit portions 10211. The plurality of first focus limit portions 10211 correspond one-to-one with the plurality of second focus limit portions 10231. When the first focus limit portions 10211 match the second focus limit portions 10231, the axis of the focus movable portion 1023 and the axis of the focus ring 1021 both coincide with the optical axis Z. The focus ring 1021 is connected to the focus movable portion 1023, which is in turn connected to the focus drive portion 1022. The focus drive portion 1022 is used to drive the focus movable portion 1023 to move, thereby driving the focus ring 1021 to move.

[0141] Since the focus driving unit 1022 is connected to the focus movable unit 1023, when the focus driving unit 1022 moves, it can drive the focus movable unit 1023 to move. After the focus movable unit 1023 moves, since the focus movable unit 1023 is connected to the focus ring 1021, when the focus movable unit 1023 moves, it can drive the focus ring 1021 to move. After the focus ring 1021 moves, the focus ring 1021 can squeeze the liquid focus lens 2, causing the curvature of the liquid focus lens 2 to change, thereby achieving the focusing function.

[0142] Among them, since the outer edge of the focus ring 1021 is provided with multiple first focus limit parts 10211, and the positions of the focus movable part 1023 are provided with multiple second focus limit parts 10231 corresponding to the multiple first focus limit parts 10211, the multiple first focus limit parts 10211 correspond one to one with the multiple second focus limit parts 10231, and when the first focus limit part 10211 is matched with the second focus limit part 10231, the axis of the focus movable part 1023 and the axis of the focus ring 1021 are both collinear with the optical axis Z. Therefore, when the focus ring 1021 is assembled onto the focus movable part 1023, under the limiting action of the first focus limit part 10211 and the second focus limit part 10231, the assembly accuracy between the focus ring 1021 and the focus movable part 1023 can be made higher.

[0143] It should be noted that the first focus limit portion 10211 and the second focus limit portion 10231 can be any possible structure, as long as the axis of the focus movable portion 1023 and the axis of the focus ring 1021 both coincide with the optical axis Z when the first focus limit portion 10211 and the second focus limit portion 10231 are matched. The embodiments of the present application do not limit the structures of the first focus limit portion 10211 and the second focus limit portion 10231.

[0144] In one possible implementation, see Figure 9 The first focus limit portion 10211 includes a limit protrusion 10212 extending outward from the outer edge of the focus ring 1021, and two claws 10213 located on both sides of the limit protrusion 10212 and extending outward along the outer edge of the focus ring 1021. The two claws 10213 form a clamping space. The second focus limit portion 10231 includes a clamping protrusion 10232 and two recessed portions 10233 located on both sides of the clamping protrusion 10232. The outer wall of the limit protrusion 10212 is in contact with the inner wall of the clamping protrusion 10232. In this way, the axis of the focus movable portion 1023 can be made collinear with the axis of the focus ring 1021. In addition, the two claws 10213 are respectively located in the two recessed portions 10233, and the clamping protrusion 10232 is located in the clamping space and is clamped in the two claws 10213. This can also prevent the focus ring 1021 from rotating relative to the focus movable portion 1023 along the axis of the focus movable portion 1023, that is, the focus ring 1021 is limited in the circumferential direction of the focus ring 1021 to prevent the focus ring 1021 from rotating in its own circumferential direction, thereby increasing the assembly accuracy between the focus movable portion 1023 and the focus ring 1021.

[0145] To sum up, in the embodiment of the present application, since the liquid anti-shake lens 1 is arranged on the supporting component 103, the anti-shake component 101 of the driving device 100 is connected to the liquid anti-shake lens 1. Therefore, when the anti-shake component 101 moves, it can drive part of the structure of the liquid anti-shake lens 1 to move relative to the supporting component 103, so that the inclination angle of the liquid anti-shake lens 1 relative to the supporting component 103 can be changed. After the inclination angle of the liquid anti-shake lens 1 changes, the angle and position of the outgoing light emitted from the liquid anti-shake lens 1 to the camera module can be changed, thereby realizing the anti-shake function.

[0146] Since the liquid focus lens 2 is arranged on the support component 103, the focus component 102 of the driving device 100 is connected to the liquid focus lens 2. Therefore, when the focus component 102 moves, it can drive part of the structure of the liquid focus lens 2 to move relative to the support component 103, so that the curvature of the liquid focus lens 2 can be changed. After the curvature of the liquid focus lens 2 changes, the position of the output light from the liquid focus lens 2 to the camera module can be changed, thereby realizing the focusing function.

[0147] It can be seen that by driving the liquid anti-shake lens 1 to move through the anti-shake component 101, the camera module can realize the anti-shake function, and by driving the liquid focus lens 2 to move through the focus component 102, the camera module can realize the focus function. That is, the anti-shake function and the focus function of the camera module are realized by different liquid lenses. In this way, the problem of poor imaging quality of the camera module caused by realizing the anti-shake function and the focus function at the same time through the same liquid lens in the related technology can be avoided.

[0148] At the same time, since the anti-shake function and the focus function are realized through different liquid lenses, the anti-shake function and the focus function can be made independent of each other, thereby avoiding the mutual influence of the anti-shake function and the focus function, making the performance of the camera module better.

[0149] Figure 10 This is a schematic diagram of the structure of an electronic device provided by an embodiment of the present application. Figure 10 , the electronic device includes a camera module 400.

[0150] Among them, the camera module 400 can have the same structure as the camera module 400 in any of the above embodiments, and can bring the same or similar beneficial effects, and the embodiments of this application will not be repeated here.

[0151] In the embodiment of the present application, since the camera module's anti-shake and focus functions are implemented using different liquid lenses, this can avoid the problem of poor image quality in the camera module. Furthermore, the anti-shake and focus functions can be made independent of each other, thereby preventing the anti-shake and focus functions from interfering with each other, thereby improving the performance of the camera module. Based on this, when an electronic device includes the camera module 400, the electronic device can achieve better image quality.

[0152] Among them, the electronic device can be a mobile phone, a tablet computer, a desktop computer or a learning machine, etc., and the embodiments of the present application do not limit the electronic device.
