The pressing assembly 30 is connected to the curved zoom guiding structure 21, and the lens holder 20 is connected to the first driving assembly 40.

In this way, while realizing the focusing function of the imaging module 1, not only can the installation space occupied within the imaging module 1 be reduced, thereby reducing the volume of the imaging module 1, but also the curved zoom of the liquid lens 10 can be realized.

[0043] In the embodiments of the present application, the above-mentioned imaging module 1 includes a liquid lens 10.

[0044] The above-mentioned liquid lens 10 can be used to collect external light and conduct it to the image sensor of the imaging module 1, so that the image sensor generates an image signal according to the received light.

[0045] In addition to the above-mentioned liquid lens 10, the above-mentioned imaging module 1 may further include a lens group 12. The lens group 12 includes at least one lens, and the at least one lens is disposed between the liquid lens 10 and the image sensor.

[0046] In the embodiments of the present application, the above-mentioned imaging module 1 further includes a lens holder 20, and the liquid lens 10 is disposed within the lens holder 20. Specifically, the lens holder 20 may be provided with a communicating first accommodation space 201, and the liquid lens 10 is accommodated within the first accommodation space 201.

[0047] The above-mentioned lens holder 20 can be any component that can accommodate the above-mentioned liquid lens 10 and through which the light collected by the liquid lens 10 can pass.

[0048] For example, the above-mentioned lens holder 20 can be the carrier 50 of the imaging module 1, and the carrier 50 is disposed on the base 60 of the imaging module 1; or, the lens holder 20 can also be other components other than the carrier 50, which is not limited herein.

[0049] The above-mentioned lens holder 20 is provided with a curved zoom guiding structure 21, which can be used to guide the components connected thereto to perform a curved motion. For example, when the above-mentioned lens holder 20 is a carrier, the above-mentioned curved zoom guiding structure 21 may include guiding threads provided on the inner wall of the carrier, and so on.

[0050] At least a part of the above-mentioned lens holder 20 can rotate, so that when at least a part of the lens holder 20 rotates, its curve zoom guiding structure 21 can guide the components connected thereto to perform a curve movement.

[0051] For example, the above-mentioned curve zoom guiding structure 21 may further include an inner ring, which is movably arranged in the carrier and is movably arranged in cooperation with the guiding thread. The liquid lens 10 is arranged inside the inner ring, and the inner ring can move relative to the liquid lens 10, and so on.

[0052] In the embodiment of the present application, the above-mentioned imaging module 1 further includes a pressing component 30. At least a part of the pressing component 30 is arranged on the light incident side of the above-mentioned liquid lens 10, and the pressing component 30 is connected to the curve zoom guiding structure 21. At least a part of the pressing component 30 can move and press the above-mentioned liquid lens 10 to expand and contract.

[0053] For example, when the above-mentioned lens holder 20 is the carrier 50 of the above-mentioned imaging module 1, the above-mentioned pressing component 30 may include a plurality of pressing pieces 31, and the plurality of sliders are arranged at intervals on the light incident side of the above-mentioned liquid lens 10 and are connected to the inner ring. When the inner ring rotates along the guiding thread, the inner ring can drive the plurality of pressing pieces 31 to rotate and move in a curve.

[0054] In the embodiment of the present application, the above-mentioned imaging module 1 further includes a first driving component 40, which is connected to the above-mentioned lens holder 20, and the first driving component 40 can drive at least a part of the lens holder 20 to rotate, so that the lens holder 20 drives the pressing component 30 to move through its curve glue guiding structure, and at least a part of the pressing component 30 presses the above-mentioned liquid lens 10, so that the liquid lens 10 expands and contracts to perform curve zoom.

[0055] The above-mentioned first driving component 40 can be any component that can drive at least a part of the above-mentioned lens holder 20 to rotate, and the first driving component 40 can be arranged in the first accommodation space 201 of the lens holder 20 or outside the first accommodation space 201, which is not limited herein.

[0056] For example, when the pressing component 30 includes the above-mentioned plurality of pressing pieces 31, the above-mentioned first driving component 40 may include a micro motor, which drives the inner ring to move along the guiding thread, so that the inner ring drives the plurality of pressing pieces 31 to move in a curve and press the liquid lens 10 to expand and contract, thereby realizing the curve zoom of the liquid lens 10.

[0057] In some embodiments, the curve zoom guiding structure 21 includes a first chute which is inclinedly arranged on the lens bracket 20, and the extrusion assembly 30 is movably clamped with the first chute, wherein:

[0058] When the first driving assembly 40 drives the lens bracket 20 to rotate, the lens bracket 20 drives the extrusion assembly 30 to slide along the first chute, so that the extrusion assembly 30 makes a curve lifting motion in the light conduction direction and extrudes the liquid lens 10.

[0059] In this embodiment, by inclinedly arranging the first chute on the lens bracket 20, the extrusion assembly 30 is movably clamped with the first chute, and when the first driving assembly 40 drives the lens bracket 20 to rotate, the lens bracket 20 can drive the extrusion assembly 30 to slide along the first chute, realizing that the extrusion assembly 30 makes a curve lifting motion in the light conduction direction, so that the extrusion assembly 30 extrudes the liquid lens 10 to expand and contract and perform curve zooming, thereby making the curve zoom guiding structure 21 simple in structure and easy to implement.

[0060] The above-mentioned first chute is a chute inclinedly arranged on the lens bracket 20, and the shape, size, quantity, setting position, etc. of the first chute can be set according to actual needs. For example, two first chutes can be inclinedly arranged circumferentially on the lens bracket 20 at the position where the liquid lens 10 is installed relative to the lens bracket 20, and the two first chutes are located on the light incident side of the liquid lens 10 and are arranged oppositely, etc.

[0061] When the curve zoom guiding structure 21 includes the above-mentioned first chute, the above-mentioned extrusion assembly 30 is movably clamped with the first chute, and it can slide along the first chute under the drive of the lens bracket 20.

[0062] For example, when the above-mentioned two first chutes are arranged on the lens bracket 20, the above-mentioned extrusion assembly 30 can be composed of two sliders corresponding to the two first chutes, and a part of each slider is movably clamped with its corresponding first chute, and the other part abuts against the light incident side of the liquid lens 10. When the lens bracket 20 rotates, each slider can slide in its corresponding first chute and extrude the liquid lens 10 to make the liquid lens 10 expand and contract to perform curve zooming.

[0063] In some embodiments, please refer to Figure 4 and 5 , the extrusion assembly 30 includes:

[0064] An extrusion member 31, the extrusion member 31 is arranged on the light incident side of the liquid lens 10, and the extrusion member 31 covers a part of the liquid lens 10;

[0065] The connecting member 32 is connected to the extrusion member 31 and is movably clamped with the first chute, wherein:

[0066] When the first driving assembly 40 drives the lens holder 20 to rotate, the connecting member 32 moves along the first chute and drives the extrusion member 31 to perform a curved lifting motion in the optical axis direction.

[0067] In this embodiment, the extrusion member 31 is arranged on the light incident side of the liquid lens 10, and is connected to the extrusion member 31 through the connecting member 32 and is movably clamped with the first chute, so that when the connection moves along the first chute, it can drive the extrusion member 31 to perform a curved lifting motion in the optical axis direction, thereby making the setting position of the first chute more flexible.

[0068] The above extrusion member 31 can be any structure that can extrude the liquid lens 10. For example, the above extrusion member 31 can include a plurality of extrusion blocks arranged on the light incident side of the liquid lens 10, and the plurality of extrusion blocks are arranged at intervals.

[0069] The above connecting member 32 can be arranged outside the above first accommodation space 201. For example, when the above extrusion member 31 includes the above plurality of extrusion blocks, the above connecting member 32 can include a plurality of connecting rods corresponding to the plurality of extrusion blocks. Each connecting rod is connected to its corresponding extrusion block and partially extends into a first chute. The plurality of connecting rods are arranged at intervals around the side surface of the lens holder 20 away from the first accommodation space 201. When the lens holder 20 rotates, each connecting rod slides along its first chute and drives the corresponding extrusion block to move.

[0070] In some embodiments, the connecting member 32 is movably arranged in the lens holder 20, and at least part of the connecting member 32 passes through the gap between the lens holder 20 and the liquid lens 10 and is connected to the extrusion member 31.

[0071] In this embodiment, the connecting member 32 is movably arranged in the lens holder 20, and at least part of the connecting member 32 passes through the gap between the lens holder 20 and the liquid lens 10 and is connected to the extrusion member 31. Thus, not only can the lens holder 20 drive the above extrusion member 31 to extrude the liquid lens 10, but also the structural arrangement of the camera module 1 can be made more flexible.

[0072] For example, in the case where the above-mentioned lens holder 20 is a cylindrical holder, the above-mentioned connecting member 32 can be set as a cylindrical connecting member 32, and the cylindrical connecting member 32 is received in the cylindrical holder and is movably connected to a chute opened on the cylindrical holder. The liquid lens 10 can be fixedly arranged in the cylindrical holder, and there is a gap between the liquid lens 10 and the cylindrical holder. A plurality of extrusion blocks are arranged on the light incident side of the liquid lens 10, and the cylindrical connecting member 32 can pass through the gap and be connected to the plurality of extrusion blocks. When the cylindrical holder rotates, the cylindrical holder can drive the cylindrical connecting member 32 to rotate through the chute, and the cylindrical connecting member 32 can drive the extrusion blocks to move and extrude the liquid lens 10, so that the liquid lens 10 undergoes curve zooming.

[0073] In some embodiments, the connecting member 32 may include:

[0074] A connecting member body 321, the connecting member body 321 is connected to the extrusion member 31, and the connecting member body 321 is movably connected to the lens holder 20;

[0075] A first connecting rod 322, the first connecting rod 322 protrudes from one side of the connecting member body 321, and the first connecting rod 322 is cooperatively arranged in the first chute;

[0076] The first driving assembly 40 can drive the lens holder 20 to drive the first connecting rod 322 to slide along the first chute, so that the connecting member body 321 drives the extrusion member 31 to move.

[0077] In this embodiment, by protruding the first connecting rod 322 from one side of the connecting member body 321, and the lens holder 20 is provided with a first chute, the first connecting rod 322 is cooperatively arranged in the first chute, and the lens holder 20 can drive the first connecting rod 322 to slide along the first chute, so that the connecting member body 321 drives the extrusion member 31 to move, realizing the extrusion member 31 to extrude the liquid lens 10 to expand and contract, thereby making the connection between the connecting member 32 and the lens holder 20 simpler and easier to implement.

[0078] For example, in the case where the above-mentioned lens holder 20 and the above-mentioned connecting member 321 are a hollow circular sleeve structure sleeved with each other, a through first chute can be opened on the outer peripheral wall of the above-mentioned lens holder 20, and the first chute is inclined with respect to a plane perpendicular to the optical axis direction X, such as Figure 5As shown in the figure. When the first driving component 40 drives the lens holder 20 to rotate counterclockwise, the first connecting rod 322 arranged in the first chute slides to the left side of the first chute, so that the movable connection body moves along the optical axis direction X, and further increases the extrusion force of the extrusion member 31 on the liquid lens 10, thereby causing the liquid lens 10 to elongate; and when the first driving component 40 drives the lens holder 20 to rotate clockwise, the first connecting rod 322 arranged in the first chute slides to the left side of the first chute, so that the movable connection body moves in the direction opposite to the optical axis direction X, and further reduces the extrusion force of the extrusion member 31 on the liquid lens 10, thereby causing the liquid lens 10 to shorten.

[0079] In some embodiments, please refer to Figure 6 and 7 again, a second chute 22 is further formed on the lens holder 20.

[0080] The imaging module 1 may further include:

[0081] a lifting bracket 70, the lifting bracket 70 is movably arranged in the lens holder 20 and is movably clamped with the second chute 22, and the liquid lens 10 is embedded in the lifting bracket 70, wherein:

[0082] When the first driving component 40 drives the lens holder 20 to rotate, the lens holder 20 drives the lifting bracket 70 to move along the second chute 22, so that the lifting bracket 70 drives the liquid lens 10 to lift along the optical axis direction.

[0083] In the embodiment of the present application, the imaging module 1 is further provided with a lifting bracket 70, and the liquid lens 10 is embedded in the lifting bracket 70, and the lifting bracket 70 is cooperatively arranged with the second chute 22 on the lens holder 20. Thus, when the first driving component 40 drives the lens holder 20, the lens holder 20 can not only drive the connecting member 32 to move, so as to realize the telescopic movement of the liquid lens 10; moreover, the lens holder 20 can also drive the lifting bracket 70 to lift, so as to realize the lifting of the liquid lens 10 along the optical axis direction, change the distance between the liquid lens 10 and the lens group 12, and achieve the purpose of zooming by the movement of the liquid lens 10.

[0084] The shapes, sizes and positions of the above-mentioned first chute and the second chute 22 can be set according to actual needs. For example, as Figure 7 shown, the above-mentioned second chute 22 and the first chute can both be set as broken-line chutes, and so on.

[0085] The above-mentioned lifting bracket 70 is movably connected to the second sliding groove 22. It can be that the lifting bracket 70 is provided with a second connecting rod 71, the second connecting rod 71 is movably arranged in the second sliding groove 22, and the lens bracket 20 can drive the second connecting rod 71 to slide along the second sliding groove 22, so that the liquid lens 10 moves up and down along the optical axis direction.

[0086] The above-mentioned first driving assembly 40 is movably connected to the above-mentioned lens bracket 20, and the first driving assembly 40 can drive the lens bracket 20 to move. It can be that the first driving assembly 40 and the lens bracket 20 are connected and driven by means of belt drive or the like.

[0087] In some embodiments, the lens bracket 20 is provided with gear teeth 24.

[0088] The first driving assembly 40 may include:

[0089] A driving motor 41;

[0090] A gear 42, the gear 42 is connected to the driving motor 41, and the gear 42 meshes with the gear teeth 24 on the lens bracket 20. The driving motor 41 drives the lens bracket 20 to move through the gear 42 and the gear teeth 24.

[0091] In this embodiment, the driving motor 41 meshes with the gear teeth 24 on the lens bracket 20 through its gear 42, so that the driving motor 41 can drive the lens bracket 20 to rotate, thereby making the transmission efficiency of the first driving assembly 40 driving the lens bracket 20 higher.

[0092] For example, when the above-mentioned lens bracket 20 is a hollow cylindrical structure, a circle of gear teeth 24 is arranged on the circumference of the lens bracket 20, and the above-mentioned gear 42 meshes with the gear teeth 24. When the above-mentioned driving motor 41 drives the gear 42 to rotate clockwise, the driving motor 41 can drive the lens bracket 20 to rotate counterclockwise through the gear 42, as Figure 8 shown; and when the above-mentioned driving motor 41 drives the gear 42 to rotate counterclockwise, the driving motor 41 can drive the lens bracket 20 to rotate clockwise through the gear 42.

[0093] When the above-mentioned lens bracket 20 is a structure other than the carrier 50 of the above-mentioned imaging module 1, the above-mentioned first driving assembly 40 can be arranged in the above-mentioned carrier 50.

[0094] In some embodiments, the imaging module 1 further includes a carrier 50, and the carrier 50 is provided with a second receiving space 500.

[0095] The lens bracket 20 and the extrusion assembly 30 can be disposed in the second accommodation space 500, and the first driving assembly 40 is embedded in the inner wall of the carrier 50.

[0096] In this embodiment, by embedding the first driving assembly 40 in the inner wall of the carrier 50, the installation space of the carrier 50 occupied by the first driving assembly 40 can be avoided, so as to reduce the volume of the carrier 50, and further reduce the volume of the camera module 1.

[0097] In the embodiment of the present application, the above-mentioned liquid lens 10 can be telescopic. When the liquid lens 10 is squeezed, the light incident side thereof bulges and elongates; or, it can also be the side away from the light incident side that bulges and elongates, which is not limited herein.

[0098] In some embodiments, a convex lens body 111 is protrudingly provided on the light incident side of the liquid lens 10; the pressing member 31 is an annular body, and the annular body surrounds the convex lens body 11.

[0099] In this embodiment, when the convex lens body 11 is protrudingly provided on the light incident side of the above-mentioned liquid lens 10, the pressing member 31 is an annular body surrounding the convex lens body 11, so that when the annular body presses the liquid lens 10, the force received by the liquid lens 10 is more balanced, and thus the deformation ability of the convex lens body 11 is stronger.

[0100] The above-mentioned annular body surrounds the convex lens body 11. When the connecting member 32 drives the annular body to move along the optical axis direction X, the pressing force of the annular body on the liquid lens 10 can be increased, so that the convex lens body 11 elongates; and when the connecting member 32 drives the annular body to move in a direction away from the optical axis direction X, the pressing force of the annular body on the liquid lens 10 is reduced, so that the convex lens body 11 contracts.

[0101] For example, as Figure 9 and 10 shown, when the lens bracket 20 rotates counterclockwise, the annular body moves along the optical axis direction X, the pressing force of the annular body on the liquid lens 10 increases, so that the convex lens body 11 elongates, and the curvature of the convex lens body 11 decreases; as Figure 11 and 12 shown, when the lens bracket 20 rotates clockwise, the annular body moves in a direction away from the optical axis direction X, the pressing force of the annular body on the liquid lens 10 decreases, so that the convex lens body 11 contracts, and the curvature of the convex lens body 11 increases.

[0102] In some embodiments, please refer to Figures 13 to 15 again. The curve zoom guiding structure 21 includes a runner.

[0103] The lens holder 20 further includes:

[0104] A holder body 23, the liquid lens 10 is disposed on the holder body 23, the rotating wheel is relatively movably disposed with respect to the holder body 23, the rotating wheel is in movable abutment with the pressing assembly 30 and is connected to the first driving assembly 40, and the wheel surface of the rotating wheel is an arc surface, wherein:

[0105] When the first driving assembly 40 drives the rotating wheel to rotate, the rotating wheel drives the pressing assembly 30 to move through the change of the radian of its wheel surface, so that the pressing assembly 30 presses the liquid lens 10 to expand and contract for curve zooming.

[0106] In this embodiment, by providing a rotating wheel connected to the first driving assembly 40 in the lens holder 20, the wheel surface of the rotating wheel is an arc surface, and the pressing assembly 30 is in movable abutment with the rotating wheel, so that when the first driving assembly 40 drives the rotating wheel to rotate, the rotating wheel can drive the pressing assembly 30 to move through the change of the radian of its wheel surface, thereby making the structure of the lens holder 20 simpler and the focusing effect better.
