The technical scheme of the application will be further described with reference to specific embodiments and drawings.

Fig. 1A is a schematic structural diagram of a liquid lens assembly according to an embodiment of the present application. Referring to fig. 1A, the liquid lens assembly includes a liquid anti-shake lens 1 and a liquid focusing lens 2. Wherein, the liquid focusing lens 2 and the liquid anti-shake lens 1 are stacked and connected with each other.

In the embodiment of the application, since the liquid lens assembly includes the liquid anti-shake lens 1 and the liquid focusing lens 2, the liquid lens assembly can realize the anti-shake function through the liquid anti-shake lens 1 and realize the focusing function through the liquid focusing lens 2. That is, for the liquid lens assembly, the anti-shake function and the focusing function are realized by different liquid lenses. In the related art, the anti-shake function and the focusing function are realized through the same liquid lens, so that the problems of blurred imaging and poor imaging quality can be avoided when the liquid lens assembly is applied to the camera module.

In addition, because the anti-shake function and the focusing function are realized through different liquid lenses, the anti-shake function and the focusing function are mutually independent, the situation that the anti-shake function and the focusing function are mutually influenced is avoided, and the performance of the liquid lens assembly is better.

In addition, since the liquid focusing lens 2 and the liquid anti-shake lens 1 are stacked and connected, the liquid focusing lens 2 and the liquid anti-shake lens 1 can be formed as an integral structure, and thus, the whole liquid lens assembly can be compact and small in structure.

The liquid focusing lens 2 and the liquid anti-shake lens 1 may be connected to each other by glue bonding, or may be connected to each other by other methods, which is not limited in the embodiment of the present application.

It is noted that the above focusing can be understood as focusing in a general sense, and also as macro (fine adjustment of focal length).

In some embodiments, referring to fig. 1B and 2, the liquid anti-shake lens 1 includes an anti-shake film 11 and an anti-shake liquid 12 (not shown in the drawings), where the anti-shake film 11 encloses an anti-shake cavity 10, and the anti-shake liquid 12 is filled in the anti-shake cavity 10. The liquid focus lens 2 includes a focus film 21 and a focus liquid 22 (not shown), wherein the focus film 21 encloses a focus cavity 20, and the focus liquid 22 is filled in the focus cavity 20. The liquid lens assembly further comprises a common transparent plate 3, and the liquid anti-shake lens 1 and the liquid focusing lens 2 are respectively connected to two sides of the common transparent plate 3.

For the liquid anti-shake lens 1, since the anti-shake film 11 encloses the anti-shake cavity 10, and the anti-shake liquid 12 is filled in the anti-shake cavity 10, when the liquid anti-shake lens 1 is subjected to external force, the anti-shake film 11 and the anti-shake liquid 12 wrapped in the anti-shake film 11 can be deformed, so that the emergent angle and position of the light passing through the liquid anti-shake lens 1 can be changed, and thus the anti-shake function can be realized. Through parcel anti-shake liquid 12 in anti-shake film 11, can make liquid anti-shake lens 1 take place deformation when receiving external force, and then can make liquid anti-shake lens 1 realize anti-shake function, design conception is ingenious, and the structure is small and exquisite, consequently, can make whole liquid anti-shake lens 1 small and exquisite.

The anti-shake film 11 may be an elastic transparent film capable of being deformed at will, and in one possible implementation, the anti-shake film 11 may be a PDMS (Polydimethylsiloxane) film, which is not limited in the embodiment of the present application. Since the PDMS film has good optical and mechanical properties, the liquid anti-shake lens 1 can be made to have better properties when the anti-shake film 11 is a PDMS film.

The anti-shake liquid 12 may be an optical liquid, and any desired optical liquid having a specific refractive index and dispersion characteristics may be selected as required on the premise that the optical liquid does not have a negative effect (such as a chemical reaction) with the anti-shake film 11 when the optical liquid is selected, and the anti-shake liquid 12 is not limited in the embodiment of the present application.

Similarly, for the liquid focusing lens 2, since the focusing film 21 encloses the focusing cavity 20, and the focusing liquid 22 is filled in the focusing cavity 20, when the liquid focusing lens 2 is subjected to an external force, the focusing film 21 and the focusing liquid 22 wrapped in the focusing film 21 can be deformed, so that the emergent angle and position of the light passing through the liquid focusing lens 2 can be changed, and the focusing function can be realized. Through the parcel focusing liquid 22 in focusing film 21, can make liquid lens 2 of focusing take place deformation when receiving external force, and then can make liquid lens 2 of focusing realize focusing the function, design conception is ingenious, and the structure is small and exquisite, consequently, can make whole liquid lens 2 of focusing small and exquisite.

The focusing film 21 may be the same as the anti-shake film 11, and the embodiments of the present application will not be described herein. The focusing liquid 22 may be the same as the anti-shake liquid 12, and the embodiments of the present application will not be described herein.

Through making liquid anti-shake lens 1 and liquid lens 2 that focuses connect in the both sides of sharing transparent plate 3 respectively, so, on the one hand, sharing transparent plate 3 can regard as the transparent plate in the liquid anti-shake lens 1 to use, also can regard as the transparent plate in the liquid lens 2 that focuses to use, namely, sharing transparent plate 3 is by liquid anti-shake lens 1 and liquid lens 2 that focuses jointly, just so, just need not to set up respective transparent plate for liquid anti-shake lens 1 and liquid lens 2 respectively alone to can make the liquid lens subassembly frivolous more.

In addition, since the liquid anti-shake lens 1 and the liquid focusing lens 2 are both lenses that are very easy to deform, the liquid lens assembly composed of the liquid anti-shake lens 1 and the liquid focusing lens 2 is soft and loose, and is not easy to assemble with other parts. Based on this, through making liquid anti-shake lens 1 and liquid lens 2 that focuses connect respectively in the both sides of sharing transparent plate 3, sharing transparent plate 3 can play the effect of supporting liquid anti-shake lens 1 and liquid lens 2 that focuses, like this, can avoid the soft condition of whole liquid lens subassembly to take place, and then make whole liquid lens subassembly and other spare part's assembly work become convenient, easy.

The material of the common transparent plate 3 may be glass or resin, and the material of the common transparent plate 3 is not limited in the embodiment of the present application.

In some embodiments, referring to fig. 3 and 4, the liquid anti-shake lens 1 further includes an anti-shake transparent plate 13, and the anti-shake transparent plate 13 is disposed on a side of the anti-shake film 11 away from the anti-shake film. Through setting up anti-shake transparent plate 13 in the one side of keeping away from sharing transparent plate 3 of anti-shake film 11, when this liquid lens subassembly was used in the module of making a video recording, anti-shake transparent plate 13 can be used for being connected with the drive arrangement in the module of making a video recording, like this, drive arrangement can drive anti-shake transparent plate 13 motion for anti-shake transparent plate 13's position changes, after anti-shake transparent plate 13's position changes, anti-shake transparent plate 13 can draw in anti-shake film 11 motion, and then can change the shape of whole liquid anti-shake lens 1, thereby can reach anti-shake's purpose.

When the liquid anti-shake lens 1 includes the anti-shake transparent plate 13, since the anti-shake transparent plate 13 can be connected with the anti-shake film 11 in a large area, the shape of the whole liquid anti-shake lens 1 can be changed greatly by slightly changing the position of the anti-shake transparent plate 13, so that the anti-shake performance is better.

In addition, because the anti-shake transparent plate 13 is connected with the anti-shake film 11 in a large area, when the anti-shake transparent plate 13 moves, the anti-shake film 11 in a large area can be driven to move along with the anti-shake transparent plate 13, and then the deformation of the whole liquid anti-shake lens 1 at each position is more uniform, so that the anti-shake performance is better.

In summary, in the embodiment of the present application, since the liquid lens assembly includes the liquid anti-shake lens 1 and the liquid focusing lens 2, the liquid lens assembly can realize the anti-shake function through the liquid anti-shake lens 1 and the focusing function through the liquid focusing lens 2. That is, for the liquid lens assembly, the anti-shake function and the focusing function are realized by different liquid lenses. In the related art, the anti-shake function and the focusing function are realized through the same liquid lens, so that the problems of blurred imaging and poor imaging quality can be avoided when the liquid lens assembly is applied to the camera module.

In addition, because the anti-shake function and the focusing function are realized through different liquid lenses, the anti-shake function and the focusing function are mutually independent, the situation that the anti-shake function and the focusing function are mutually influenced is avoided, and the performance of the liquid lens assembly is better.

In addition, since the liquid focusing lens 2 and the liquid anti-shake lens 1 are stacked and connected, the liquid focusing lens 2 and the liquid anti-shake lens 1 can be formed as an integral structure, and thus, the whole liquid lens assembly can be compact and small in structure.

Furthermore, the liquid anti-shake lens 1 and the liquid focusing lens 2 are respectively connected to two sides of the common transparent plate 3, so that, on one hand, the common transparent plate 3 can be used as a transparent plate in the liquid anti-shake lens 1 and also can be used as a transparent plate in the liquid focusing lens 2, that is, the common transparent plate 3 is jointly used by the liquid anti-shake lens 1 and the liquid focusing lens 2, and thus, the liquid lens assembly can be lighter and thinner without separately arranging respective transparent plates for the liquid anti-shake lens 1 and the liquid focusing lens 2.

In the embodiment of the application, since the common transparent plate 3 is fixedly arranged on the supporting component 103, the liquid anti-shake lens 1 is arranged on the common transparent plate 3, and the anti-shake component 101 of the driving device 100 is connected with the liquid anti-shake lens 1, when the anti-shake component 101 moves, part of the structure of the liquid anti-shake lens 1 can be driven 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, and after the inclination angle of the liquid anti-shake lens 1 is changed, the angle, the position and the like of emergent light rays of the liquid anti-shake lens 1 emergent into the camera module can be changed, thereby realizing the anti-shake function.

Because the liquid focusing lens 2 is disposed on the common transparent plate 3, the focusing assembly 102 of the driving device 100 is connected with the liquid focusing lens 2, when the focusing assembly 102 moves, a part of the structure of the liquid focusing lens 2 can be driven to move relative to the supporting assembly 103, so that the curvature of the liquid focusing lens 2 can be changed, and after the curvature of the liquid focusing lens 2 is changed, the position of the emergent light rays from the liquid focusing lens 2 to the camera module can be changed, so that the focusing function can be realized.

Therefore, the anti-shake module 101 drives the liquid anti-shake lens 1 to move, so that the camera module can realize an anti-shake function, the focusing module 102 drives the liquid focusing lens 2 to move, and the camera module can realize a focusing function, that is, the anti-shake function and the focusing function of the camera module are realized through different liquid lenses (namely, the liquid anti-shake lens 1 and the liquid focusing lens 2), so that the problem of poor imaging quality of the camera module caused by simultaneously realizing the anti-shake function and the focusing function through the same liquid lens in the related art can be avoided.

Meanwhile, the anti-shake function and the focusing function are realized through different liquid lenses, so that the anti-shake function and the focusing function are mutually independent, the situation that the anti-shake function and the focusing function are mutually influenced can be avoided, and the performance of the camera module is better.

In some embodiments, referring to fig. 5 and 6, the camera module further includes a support ring 300, the common transparent plate 3 is connected to the support ring 300, and the support ring 300 is fixedly disposed on the support assembly 103.

In addition, since the common transparent plate 3 is fixedly disposed on the support assembly 103 through the support ring 300, the support ring 300 can support the common transparent plate 3, and thus the common transparent plate 3 can be prevented from being damaged.

In some embodiments, referring to fig. 7A and 7B, the supporting component 103 is provided with a plurality of positioning portions 1031 extending along the optical axis Z towards a side close to the common transparent plate 3, the positioning portions 1031 enclose to form a positioning cavity 1030 (i.e. an area where a dotted line is located in fig. 7B), the supporting ring 300 is accommodated in the positioning cavity 1030, and an outer annular wall of the supporting ring 300 is attached to a side of the positioning portion 1031 close to the optical axis Z. Through making the holding of support ring 300 in location chamber 1030 and making the outer annular wall of support ring 300 laminate with the one side that location portion 1031 is close to optical axis Z, location portion 1031 can fix a position support ring 300, and then makes when assembling support ring 300 to supporting component 103, assembly precision is higher.

The positioning portion 1031 may be a protrusion extending along a direction approaching the support ring 300 or other possible structures, which is not limited in the embodiment of the present application.

The number of the positioning portions 1031 may be 4 or may be other, and the embodiment of the present application is not limited thereto.

In some embodiments, referring to fig. 7A, the outer edge of the support ring 300 is provided with first recognition portions 301 at intervals, the common transparent plate 3 is provided with second recognition portions 31 matching the first recognition portions 301, and when the first recognition portions 301 are aligned with the second recognition portions 31, the axis of the support ring 300 is collinear with the axis of the common transparent plate 3.

Since the axis of the support ring 300 is collinear with the axis of the common transparent plate 3 when the first recognition portion 301 is aligned with the second recognition portion 31, the axis of the support ring 300 can be made collinear with the axis of the common transparent plate 3 by aligning the first recognition portion 301 with the second recognition portion 31 when the work of assembling the support ring 300 to the common transparent plate 3 is performed, and thus, the assembling accuracy of the support ring 300 when assembled to the common transparent plate 3 can be made higher, and thus, the assembling accuracy of the entire camera module can be made higher.

Specifically, in some embodiments, referring to fig. 7A, the first identifying portion 301 is a plurality of first protrusions spaced along an outer edge of the support ring 300, and distances between a face of the plurality of first protrusions away from an axis of the support ring 300 and the axis of the support ring 300 are all first distances. The second identifying portion 31 is a plurality of second protrusions arranged along the outer edge of the common transparent plate 3 at intervals, the distances between the surface of the plurality of second protrusions, which is far away from the axis of the common transparent plate 3, and the axis of the common transparent plate 3 are all second distances, the second protrusions are in one-to-one correspondence with the first protrusions, and the first distances are equal to the second distances.

Since the second protrusions are in one-to-one correspondence with the first protrusions and the first distance between the side of the first protrusions remote from the axis of the support ring 300 and the axis of the support ring 300 is equal to the second distance between the side of the second protrusions remote from the axis of the common transparent plate 3 and the axis of the common transparent plate 3, when the first protrusions are aligned with the second protrusions, the axis of the support ring 300 will be collinear with the axis of the common transparent plate 3. The manner of making the axis of the support ring 300 and the axis of the common transparent plate 3 collinear is very simple, and therefore, the manufacturing costs of the first recognition portion 301 and the second recognition portion 31 can be reduced to some extent.

The number of the first recognition portions 301 may be 4 or other, and the number of the first recognition portions 301 is not limited in the embodiment of the present application. Similarly, the number of the second identifying portions 31 may be 4, or may be other, and the number of the second identifying portions 31 is not limited in the embodiment of the present application.

In some embodiments, referring to FIG. 5, the anti-shake assembly 101 includes a connection plate 1011, a plurality of legs 1012, and an anti-shake driving part 1013. Wherein, the connecting plate 1011 is connected with one side of the liquid anti-shake lens 1 far away from the common transparent plate 3. The plurality of legs 1012 extend from the outer edge of the connection plate 1011 toward the side close to the common transparent plate 3, the plurality of legs 1012 are covered on the periphery of the support ring 300, the plurality of legs 1012 are arranged at intervals, gaps are formed between the adjacent legs 1012, and the first recognition portions 301 correspond to the positions of the gaps. The anti-shake driving part 1013 is connected with the leg 1012, and the anti-shake driving part 1013 is used for driving the leg 1012 to move, and then driving the connecting plate 1011 to move so as to change the inclination angle of the liquid anti-shake lens 1.

In this embodiment, since the anti-shake driving part 1013 is connected to the leg part 1012, the leg part 1012 can be driven to move when the anti-shake driving part 1013 moves, and since the leg part 1012 is formed by extending the outer edge of the connection plate 1011, the connection plate 1011 can be driven to move when the leg part 1012 moves. After the connection plate 1011 moves, since the connection plate 1011 is connected with a side of the liquid anti-shake lens 1 away from the common transparent plate 3, when the connection plate 1011 moves, the liquid anti-shake lens 1 can be deformed, and thus the inclination angle of the liquid anti-shake lens 1 can be changed. After the inclination angle of the liquid anti-shake lens 1 changes, the camera module can realize the anti-shake function.

Since the plurality of legs 1012 are covered on the periphery of the support ring 300 and the plurality of legs 1012 are spaced apart, a gap is formed between adjacent legs 1012, and the first recognition portion 301 corresponds to the position of the gap. In this way, the leg 1012 and the first recognition portion 301 will not interfere with each other, so that the dispensing operation between the first recognition portion 301 and the second recognition portion 31 is facilitated, and the assembly operation of the whole camera module is simplified.

The number of the legs 1012 may be 4, or may be other numbers, for example, 2 or 3, etc., and the number of the legs 1012 is not limited in the embodiment of the present application.

Through making the liquid focus lens 2 be connected with the one side of sharing transparent plate 3 that keeps away from liquid anti-shake lens 1 and make liquid focus lens 2 be located holding ring 300, holding ring 300 can be with the at least partial structure of liquid focus lens 2 around in the intra-annular of self, like this, holding ring 300 can play the effect of protection liquid focus lens 2 to a certain extent for liquid focus lens 2's life is longer.

Further, in some embodiments, referring to fig. 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 smaller than or equal to the thickness of the liquid focusing lens 2, the support ring 300 can utilize the thickness space of the liquid focusing lens 2 to accommodate its own structure, so that the support ring 300 will not affect the overall thickness of the liquid lens assembly, and thus the whole camera module is more compact.

In some embodiments, referring to FIG. 6, the focus assembly 102 includes a focus ring 1021 and a focus drive 1022. The focusing ring 1021 is connected with one side of the liquid focusing lens 2 far away from the common transparent plate 3. The focusing driving part 1022 is connected to the focusing ring 1021, and the focusing driving part 1022 is used for driving the focusing ring 1021 to move so as to change the curvature of the liquid focusing lens 2.

In this embodiment, since the focus driving portion 1022 is connected to the focus ring 1021, when the focus driving portion 1022 moves, the focus ring 1021 is driven to move, and since the focus ring 1021 is connected to a 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 press the liquid focus lens 2 so that the curvature of the liquid focus lens 2 changes, and thus, a focusing function can be achieved.

Since the focusing ring 1021 is of a ring-shaped structure, as the focusing ring 1021 gradually presses the liquid focusing lens 2, the curvature of the liquid focusing lens 2 at the position corresponding to the middle cavity of the focusing ring 1021 will change. It is understood that when the focus ring 1021 is of a ring-like structure, the liquid focus lens 2 can be pressed in the entire circumferential direction of the focus ring 1021, and thus, the curvature change of the liquid focus lens 2 can be made more uniform. Based on this, when the curvature of the liquid focus lens 2 is changed by the focus ring 1021, the curvature change of the liquid focus lens 2 can be made more uniform, and the focusing performance of the image pickup module is made better.

Note that, the focus driving portion 1022 may be any structure capable of driving the focus ring 1021 to move, and the focus driving portion 1022 is not limited in the embodiment of the present application.

The focusing ring 1021 is connected with the focusing movable part 1023, the focusing movable part 1023 is connected with the focusing driving part 1022, and the focusing driving part 1022 is used for driving the focusing movable part 1023 to move so as to drive the focusing ring 1021 to move.

Since the focus driving section 1022 is connected to the focus movable section 1023, the focus driving section 1022 can move to drive the focus movable section 1023. After the focusing movable part 1023 moves, since the focusing movable part 1023 is connected with the focusing ring 1021, when the focusing movable part 1023 moves, the focusing ring 1021 can be driven to move, and after the focusing ring 1021 moves, the focusing ring 1021 can press the liquid focusing lens 2, so that the curvature of the liquid focusing lens 2 is changed, and the focusing function can be realized.
