The technical solutions of the present application will be further described with reference to the following specific embodiments and accompanying 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: liquid anti-shake lens 1 and liquid focusing lens 2. The liquid focusing lens 2 and the liquid anti-shake lens 1 are stacked and connected to each other.

In this application embodiment, because liquid lens subassembly includes liquid anti-shake lens 1 and liquid lens 2 of focusing, consequently, liquid lens subassembly can realize the anti-shake function through liquid anti-shake lens 1, focuses the function through liquid lens 2 realization of focusing. That is, for the liquid lens assembly, the anti-shake function and the focusing function are realized by different liquid lenses. In this and the correlation technique, the mode that anti-shake function and function of focusing all realized through same liquid lens can avoid when liquid lens subassembly is used in the module of making a video recording, and the problem that formation of image is fuzzy and the formation of image quality is not good takes place.

In addition, because the liquid focusing lens 2 and the liquid anti-shake lens 1 are stacked and connected to each other, the liquid focusing lens 2 and the liquid anti-shake lens 1 can be formed into an integrated structure, so that the whole liquid lens assembly is compact and small.

The liquid focusing lens 2 and the liquid anti-shake lens 1 can be connected with each other in a glue bonding mode, and also can be connected with each other in other modes, and the embodiment of the application does not limit the connection.

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

In some embodiments, referring to fig. 1B and fig. 2, the liquid anti-shake lens 1 includes: an anti-shake film 11 and an anti-shake liquid 12 (not shown), 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. The liquid focus lens 2 includes: focusing film 21 and focusing liquid 22 (not shown in the figure), focusing film 21 encloses to form focusing cavity 20, and focusing liquid 22 is filled in focusing 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.

To liquid anti-shake lens 1, because anti-shake film 11 encloses to close and forms anti-shake cavity 10, anti-shake liquid 12 fills in anti-shake cavity 10, consequently, liquid anti-shake lens 1 is when receiving external force, anti-shake film 11 and the anti-shake liquid 12 of parcel in anti-shake film 11 all can take place deformation, like this, can be so that the emergence angle and the position etc. that pass the light in liquid anti-shake lens 1 change, so, can realize the anti-shake function. Through wrapping up in 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 the anti-shake function, the design concept is ingenious, and the structure is small and exquisite, consequently, can be so that whole liquid anti-shake lens 1 is small and exquisite.

Wherein, the above-mentioned anti-shake film 11 can refer to the elastic transparent film that can take place deformation wantonly, and in a possible implementation, anti-shake film 11 can be PDMS (Polydimethylsiloxane) film, and this application embodiment does not do the restriction to this. Because the PDMS film has good optical properties and mechanical properties, when the anti-shake film 11 is a PDMS film, the liquid anti-shake lens 1 can have better properties.

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

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, both the focusing film 21 and the focusing liquid 22 wrapped in the focusing film 21 can be deformed, so that the exit angle and the position of light passing through the liquid focusing lens 2 can be changed, and thus, the focusing function can be realized. Through wrapping up the liquid 22 of focusing in focusing film 21, can make liquid focus lens 2 take place the deformation when receiving external force, and then can make liquid focus lens 2 realize the function of focusing, the design concept is ingenious, and the structure is small and exquisite, consequently, can make whole liquid focus lens 2 small and exquisite.

The focusing film 21 may be the same as the anti-shake film 11, and the description of the embodiments of the present application is omitted here. The focusing liquid 22 may also be the same as the anti-shake liquid 12, and the description of the embodiment of the present application is omitted here.

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

In addition, since the liquid anti-shake lens 1 and the liquid focusing lens 2 are both lenses that are easily deformed, the liquid lens assembly formed by the liquid anti-shake lens 1 and the liquid focusing lens 2 is soft and not easy to assemble with other components. Based on this, through making liquid anti-shake lens 1 and liquid focus lens 2 and connect respectively in the both sides of sharing transparent plate 3, sharing transparent plate 3 can play the effect that supports liquid anti-shake lens 1 and liquid focus lens 2, like this, can avoid the soft condition of whole liquid lens subassembly pine to take place, and then make the assembly work of whole liquid lens subassembly with other spare parts 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 far side of the anti-shake film 11. Set up anti-shake transparent plate 13 through the one side of keeping away from sharing transparent plate 3 at anti-shake film 11, when this liquid lens subassembly is 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, thus, drive arrangement can drive anti-shake transparent plate 13 and move, make the position of anti-shake transparent plate 13 change, after the position of anti-shake transparent plate 13 changes, anti-shake transparent plate 13 can pin anti-shake film 11 and move, and then can change the shape of whole liquid anti-shake lens 1, thereby can reach the purpose of anti-shake.

When liquid anti-shake lens 1 includes anti-shake transparent plate 13, because anti-shake transparent plate 13 can be connected with anti-shake film 11 large tracts of land, like this, through making the position of anti-shake transparent plate 13 take place slight change, can make whole liquid anti-shake lens 1's shape take place great change, so, can make anti-shake performance better.

In addition, because anti-shake transparent plate 13 and the connection of anti-shake film 11 large tracts of land, consequently, when anti-shake transparent plate 13 moved, can drive the anti-shake film 11 of large tracts of land and all follow anti-shake transparent plate 13 and move together, and then can be so that the deformation of whole liquid anti-shake lens 1 in each position department is more even to can make the anti-shake performance better.

To sum up, in this application embodiment, because liquid lens subassembly includes liquid anti-shake lens 1 and liquid lens 2 of focusing, consequently, liquid lens subassembly can realize the anti-shake function through liquid anti-shake lens 1, focuses the function through liquid lens 2 of focusing. 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 by the same liquid lens, so that the problems of imaging blur and poor imaging quality when the liquid lens assembly is applied to a camera module can be avoided.

Furthermore, through making liquid anti-shake lens 1 and liquid focus lens 2 connect respectively in the both sides of sharing transparent plate 3, thus, on the one hand, sharing transparent plate 3 can be used as the transparent plate in liquid anti-shake lens 1, also can be used as the transparent plate in liquid focus lens 2, that is, sharing transparent plate 3 is used jointly by liquid anti-shake lens 1 and liquid focus lens 2, and like this, just need not to set up respective transparent plate separately for liquid anti-shake lens 1 and liquid focus lens 2 respectively, thereby can make liquid lens subassembly more frivolous.

In the embodiment of the application, because the fixed setting of sharing transparent plate 3 is on supporting component 103, liquid anti-shake lens 1 sets up on sharing transparent plate 3, drive arrangement 100's anti-shake subassembly 101 is connected with liquid anti-shake lens 1, therefore, when anti-shake subassembly 101 moves, can drive the relative supporting component 103 motion of partial structure of liquid anti-shake lens 1, thereby can make the inclination of liquid anti-shake lens 1 relative supporting component 103 change, after the inclination of liquid anti-shake lens 1 changes, can make the angle and the position etc. that liquid anti-shake lens 1 emergent to the emergent light in the camera module change, thereby can realize the anti-shake function.

Since the liquid focusing lens 2 is disposed on the common transparent plate 3, and the focusing assembly 102 of the driving device 100 is connected to 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 emitted from the liquid focusing lens 2 to the camera module and the like can be changed, thereby realizing the focusing function.

It can be seen that 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, and the focusing module 102 drives the liquid focusing lens 2 to move, so that 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 (i.e., 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 the fact that the anti-shake function and the focusing function are simultaneously realized through the same liquid lens in the related art can be avoided.

Simultaneously, because the anti-shake function is realized through the liquid lens of difference with the function of focusing with focusing, like this, can be so that the anti-shake function with focus the function mutual independence, and then can avoid the anti-shake function and focus the condition that the function influences each other and take place for the performance of this module of making a video recording 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.

Because the supporting ring 300 is fixedly disposed on the supporting assembly 103, and the common transparent plate 3 is connected to the supporting ring 300, the liquid anti-shake lens 1 and the liquid focusing lens 2 are fixedly disposed on the supporting assembly 103 through the common transparent plate 3 and the supporting ring 300, so that the liquid anti-shake lens 1 and the liquid focusing lens 2 can be protected by the common transparent plate 3 and the supporting ring 300, and the liquid anti-shake lens 1 and the liquid focusing lens 2 are prevented from being damaged in the process of directly fixing the liquid anti-shake lens 1 and the liquid focusing lens 2 on the supporting assembly 103.

In addition, since the common transparent plate 3 is fixed to 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 assembly 103 is provided with a plurality of positioning portions 1031 extending toward a side close to the common transparent plate 3 along the optical axis Z, the plurality of positioning portions 1031 surround 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 surface of the positioning portion 1031 close to the optical axis Z. Through making the support ring 300 holding in location chamber 1030 and making the outer annular wall of support ring 300 laminate mutually with the one side that the location portion 1031 is close to optical axis Z, location portion 1031 can fix a position support ring 300, and then when making on assembling support ring 300 to supporting component 103, the assembly precision is higher.

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.

The number of the positioning portions 1031 may be 4, or may be another number, which is not limited in the embodiment of the present application.

In some embodiments, referring to fig. 7A, the outer edge of the supporting ring 300 is provided with first identification portions 301 at intervals, the common transparent plate 3 is provided with second identification portions 31 matching the first identification portions 301, and when the first identification portions 301 and the second identification portions 31 are aligned, the axis of the supporting 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 part 301 and the second recognition part 31 are aligned, when the work of assembling the support ring 300 to the common transparent plate 3 is performed, the axis of the support ring 300 and the axis of the common transparent plate 3 can be collinear by aligning the first recognition part 301 and the second recognition part 31, so that the assembling accuracy when the support ring 300 is assembled to the common transparent plate 3 can be high, and the assembling accuracy of the whole camera module can be high.

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

Since the second protrusions correspond to the first protrusions one-to-one, and a first distance between a face of the first protrusion far from the axis of the support ring 300 and the axis of the support ring 300 is equal to a second distance between a face of the second protrusion far from the axis of the common transparent board 3 and the axis of the common transparent board 3, when the first protrusion is aligned with the second protrusion, the axis of the support ring 300 will be collinear with the axis of the common transparent board 3. Since it is very simple to realize that the axis of the support ring 300 and the axis of the common transparent plate 3 are collinear, the manufacturing cost of the first identification portion 301 and the second identification portion 31 can be reduced to some extent.

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

In some embodiments, referring to fig. 5, the anti-shake assembly 101 comprises: a connecting plate 1011, a plurality of legs 1012, and an anti-shake drive unit 1013. The connecting plate 1011 is connected to a side of the liquid anti-shake lens 1 away from the common transparent plate 3. A 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 cover the periphery of the support ring 300, and the plurality of legs 1012 are arranged at intervals, a gap is formed between adjacent legs 1012, and the first identification part 301 corresponds to the position of the gap. The anti-shake driving portion 1013 is connected to the leg portion 1012, and the anti-shake driving portion 1013 is configured to drive the leg portion 1012 to move, and further drive 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 is moved when the anti-shake driving part 1013 moves, and since the leg part 1012 is formed by extending the outer edge of the connecting plate 1011, the connecting plate 1011 is moved when the leg part 1012 moves. After the connecting plate 1011 moves, because the connecting plate 1011 is connected with one side of the liquid anti-shake lens 1 far away from the shared transparent plate 3, therefore, when the connecting plate 1011 moves, the liquid anti-shake lens 1 can be deformed, and then 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 outer periphery of the support ring 300 and the plurality of legs 1012 are spaced apart, a gap is formed between the adjacent legs 1012, and the first recognition part 301 corresponds to the position of the gap. In this way, the leg portion 1012 and the first recognition portion 301 will not interfere with each other, which facilitates the dispensing operation between the first recognition portion 301 and the second recognition portion 31, and makes the assembly operation of the entire camera module more concise.

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

The anti-shake drive unit 1013 is configured to drive the leg 1012 to move, and the anti-shake drive unit 1013 is not limited in the present embodiment.

In some embodiments, referring to fig. 6, the supporting ring 300 is located on a side of the common transparent plate 3 away from the liquid anti-shake lens 1, the liquid focusing lens 2 is connected to a side of the common transparent plate 3 away from the liquid anti-shake lens 1, and the liquid focusing lens 2 is located in the supporting ring 300.

By connecting the liquid focusing lens 2 with the surface of the common transparent plate 3 away from the liquid anti-shake lens 1 and locating the liquid focusing lens 2 in the support ring 300, the support ring 300 can surround at least part of the structure of the liquid focusing lens 2 in the ring, so that the support ring 300 can protect the liquid focusing lens 2 to a certain extent, and the liquid focusing lens 2 has a longer service life.

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 less 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, and thus the support ring 300 will not affect the overall thickness of the liquid lens assembly, thereby making the whole camera module smaller.

In some embodiments, referring to fig. 6, the focusing assembly 102 comprises: a focus ring 1021 and a focus driving unit 1022. The focusing ring 1021 is connected to the liquid focusing lens 2 at a side far from the common transparent plate 3. The focusing driving portion 1022 is connected to the focusing ring 1021, and the focusing driving portion 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 focusing driving portion 1022 is connected to the focusing ring 1021, when the focusing driving portion 1022 moves, the focusing ring 1021 can be driven to move, and since the focusing ring 1021 is connected to one side of the liquid focusing lens 2 away from the common transparent plate 3, when 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 changes, and thus, the focusing function can be achieved.

Since the focusing ring 1021 is of an annular 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 can be understood that, when the focus ring 1021 has a ring-shaped 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 of the liquid focus lens 2 can be changed more uniformly, and the focusing performance of the camera module is better.

The focus driving unit 1022 may be any configuration capable of driving the focus ring 1021 to move, and the focus driving unit 1022 is not limited in the embodiment of the present application.

In some embodiments, referring to fig. 5 and 6, the connection plate 1011 has a first light passing hole 1010, the focusing ring 1021 has a second light passing hole 1020, the axis of the first light passing hole 1010 coincides with the axis of the second light passing hole 1020, and the diameter of the first light passing hole 1010 is larger than the diameter of the second light passing hole.

Through making the axis of the first unthreaded hole 1010 and the axis coincidence of the second unthreaded hole 1020 crossed and the diameter of the first unthreaded hole 1010 was greater than the diameter of the second unthreaded hole, can avoid the emergence of the ghost condition, consequently, can make the performance of this module of making a video recording better.

The focusing assembly 102 further includes a focusing moving portion 1023, a plurality of second focusing limiting portions 10231 are disposed at positions of the focusing moving portion 1023 corresponding to the plurality of first focusing limiting portions 10211, the plurality of first focusing limiting portions 10211 correspond to the plurality of second focusing limiting portions 10231 one by one, and when the first focusing limiting portions 10211 are matched with the second focusing limiting portions 10231, axes of the focusing moving portion 1023 and axes of the focusing ring 1021 are coincident with the optical axis Z. The focusing ring 1021 is connected with the focusing moving part 1023, the focusing moving part 1023 is connected with the focusing driving part 1022, and the focusing driving part 1022 is used for driving the focusing moving part 1023 to move so as to drive the focusing ring 1021 to move.

Since the focus driving part 1022 is connected to the focus moving part 1023, when the focus driving part 1022 moves, the focus moving part 1023 can be moved. After the movable focusing portion 1023 moves, because the movable focusing portion 1023 is connected to the focusing ring 1021, when the movable focusing portion 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 changes, and thus, the focusing function can be realized.

Since the plurality of first focus limiting parts 10211 are disposed at the outer edge of the focusing ring 1021, the plurality of second focus limiting parts 10231 are disposed at the positions of the focusing moving part 1023 corresponding to the plurality of first focus limiting parts 10211, the plurality of first focus limiting parts 10211 and the plurality of second focus limiting parts 10231 are in one-to-one correspondence, and when the first focus limiting parts 10211 and the second focus limiting parts 10231 are matched, the axis of the focusing moving part 1023 and the axis of the focusing ring 1021 are collinear with the optical axis Z, when the focusing ring 1021 is assembled to the focusing moving part 1023, the assembly precision between the focusing ring 1021 and the focusing moving part 1023 can be higher under the limiting action of the first focus limiting parts 10211 and the second focus limiting parts 10231.

It should be noted that, the first focus limiting portion 10211 and the second focus limiting portion 10231 may be any possible structures, and only need to be able to make the axis of the focus moving portion 1023 and the axis of the focus ring 1021 coincide with the optical axis Z when the first focus limiting portion 10211 and the second focus limiting portion 10231 are matched, and the embodiments of the present application do not limit the structures of the first focus limiting portion 10211 and the second focus limiting portion 10231.

In one possible implementation, referring to fig. 9, first focus limiting part 10211 includes a limiting protrusion 10212 extending outward from the outer edge of focusing ring 1021, and two claws 10213 located at both sides of limiting protrusion 10212 and extending outward along the outer edge of focusing ring 1021, two claws 10213 form a clamping space, second focus limiting part 10231 includes a clamping protrusion 10232 and two recesses 10233 located at both sides of clamping protrusion 10232, and the outer wall of limiting protrusion 10212 is attached to the inner wall of clamping protrusion 10232, so that the axis of focusing movable part 1023 is collinear with the axis of focusing ring 1021. In addition, two claws 10213 are respectively located in two recessed portions 10233, and the engaging protrusion 10232 is located in the engaging space and engaged with the two claws 10213, so that it is also possible to prevent the focusing ring 1021 from rotating along the axis of the focusing movable portion 1023 relative to the focusing movable portion 1023, that is, to prevent the focusing ring 1021 from being limited in the circumferential direction of the focusing ring 1021, and to prevent the focusing ring 1021 from rotating in the circumferential direction of itself, so that the assembling precision between the focusing movable portion 1023 and the focusing ring 1021 is higher.
