Description

Technical Field

[0001] The present application relates to the field of camera technology, and in particular to an anti-shake mechanism, a camera module and an electronic device. Background Art

[0002] In the related art, a camera module usually includes a liquid lens and an anti-shake mechanism. The anti-shake mechanism is connected to the liquid lens and is used to drive the liquid lens to swing for anti-shake.

[0003] However, in the process of driving the liquid lens to swing through the anti-shake mechanism, the liquid lens often swings unevenly, which makes the anti-shake effect of the camera module poor. Based on this, a new anti-shake mechanism is urgently needed to solve the above problem. Summary of the invention

[0004] The present application discloses an anti-shake mechanism, a camera module and an electronic device, which can make the anti-shake mechanism compact and light.

[0005] In order to achieve the above-mentioned purpose, on the one hand, the present application discloses an anti-shake mechanism for connecting with a liquid lens, the anti-shake mechanism comprising:

[0006] A first pusher, the first pusher comprising a first light-passing hole, the liquid lens being disposed at the first light-passing hole;

[0007] A connecting member, the connecting member comprising a first connecting portion extending along the axis direction of the first light-passing hole, one end of the first connecting portion being connected to an outer edge of the first pushing member;

[0008] A driving member, wherein the driving member is connected to an end of the first connecting portion away from the first pushing member, and the driving member is used to drive the first connecting portion to move, thereby driving the liquid lens to swing to change the tilt angle of the liquid lens.

[0009] When anti-shake is performed, since the driving member is connected to the first connecting part, when the driving member moves, the first connecting part can be driven to move. When the first connecting part moves, since the first connecting part is connected to the first pushing member, the first pushing member can be moved. At this time, since the first pushing member includes a first light hole and the liquid lens is arranged at the first light hole, when the first pushing member moves, the liquid lens can be driven to swing, thereby changing the inclination angle of the liquid lens. Based on this, when the anti-shake mechanism is applied to a camera module, after the inclination angle of the liquid lens changes, the angle, position, etc. of the light entering the camera module through the first light hole and the liquid lens can be changed, thereby enabling the camera module to achieve an anti-shake function.

[0010] Among them, when achieving the purpose of driving the liquid lens to swing, since the liquid lens is arranged at the first light hole of the first pusher, the purpose of driving the liquid lens to swing can be achieved by making the first pusher swing, and the swing of the first pusher is achieved by the driving member driving the first connecting part to move. In this way, the driving force of the driving member will be transmitted to the first pushing member through the first connecting part. In other words, the driving force of the driving member will not directly act on the first pushing member. The first connecting part can play a role in transmitting the driving force, and then can play a role in uniformly transmitting the driving force of the driving member to the first pushing member. When the driving force of the driving member can be uniformly transmitted to the first pushing member, the first pushing member can swing more evenly, and then the liquid lens can swing more evenly. Based on this, when the anti-shake mechanism is used in the camera module, the anti-shake effect of the camera module can be improved.

[0011] Optionally, the connecting member also includes a second connecting portion, a first end of the second connecting portion is connected to an end of the first connecting portion away from the first pushing member, a second end of the second connecting portion extends in a direction away from the axis of the first light hole, and the driving member is connected to the second end of the second connecting portion.

[0012] When anti-shake is performed, since the driving member is connected to the second connecting part, when the driving member moves, the second connecting part can be driven to move. When the second connecting part moves, since the first connecting part is respectively connected to the second connecting part and the first pushing member, the first pushing member can be moved, and then the liquid lens can be driven to swing, thereby realizing the anti-shake function.

[0013] Among them, since the first connecting part extends along the axis direction of the first light hole, one end of the first connecting part is connected to the outer edge of the first pushing member, the first end of the second connecting part is connected to the end of the first connecting part away from the first pushing member, and the second end of the second connecting part extends in the direction away from the axis of the first light hole, therefore, the first pushing member, the first connecting part and the second connecting part can form a "staircase" structure together. When the first pushing member, the first connecting part and the second connecting part form a "staircase" structure together, an empty space can be formed between the first connecting part and the second connecting part, so that the volume occupied by the connecting member can be smaller, and the volume of the anti-shake mechanism can be made more compact. At the same time, the above-mentioned empty space can be vacated to place other components, and the entire anti-shake mechanism can be further compact.

[0014] Optionally, one end of the first connection portion is connected to an outer edge of the first pushing member through a third connection portion, and the third connection portion extends from the outer edge of the first pushing member in a direction away from the axis of the first light hole.

[0015] When one end of the first connection part is connected to the outer edge of the first pushing member through the third connection part, and the third connection part extends from the outer edge of the first pushing member in a direction away from the axis of the first light hole, a first distance between one end of the second connection part away from the axis of the first light hole and the outer edge of the first pushing member is equal to the sum of the length of the third connection part and the length of the second connection part. That is to say, when the first distance remains unchanged, the length of the second connection part can be shortened by setting the third connection part. In this way, when the second connection part is subjected to the swinging force from the driving member, the length of the second connection part is shortened, and therefore, the strength of the second connection part will become stronger and less likely to deform, thereby making the strength of the entire anti-shake mechanism stronger and less likely to deform.

[0016] Optionally, the first pushing member is a circular ring structure, and the inner ring wall of the circular ring structure encloses the first light passing hole.

[0017] By making the first pushing member into a circular ring structure, since the circular ring structure is not prone to stress concentration, the first pushing member is not prone to deformation or breakage, and the strength of the entire anti-shake mechanism can be made higher.

[0018] Optionally, there are multiple connecting members, and the multiple connecting members are arranged at intervals on the outer edge of the first pushing member.

[0019] By providing a plurality of connecting members and arranging the plurality of connecting members at intervals on the outer edge of the first pushing member, the plurality of connecting members can jointly support the first pushing member at a plurality of different positions of the first pushing member, thereby making the first pushing member less susceptible to deformation.

[0020] Optionally, the first connecting portion is an arc-shaped structure, and an axis of the arc-shaped structure is parallel to an axis of the first light passing hole.

[0021] By making the first connecting part an arc-shaped structure and making the axis of the arc-shaped structure parallel to the axis of the first light hole, the first connecting part can be more capable of withstanding forces parallel to the axis of the first light hole, thereby making the first connecting part less likely to deform, thereby making the strength of the entire anti-shake mechanism higher.

[0022] Optionally, the anti-shake mechanism further includes a second pushing member, and a plurality of the second connecting parts are connected to the driving member via the second pushing member.

[0023] By connecting all the second connecting parts to the second pushing member and then connecting the second pushing member to the driving member, the second pushing member can fix the multiple second connecting parts on itself. In this way, the positional relationship between the multiple second connecting parts can be restrained by the second pushing member, so that the multiple second connecting parts form a whole, that is, the multiple connecting members form a whole. In this way, the strength of the whole formed by the multiple connecting members can be made stronger, and the strength of the entire anti-shake mechanism can be made higher.

[0024] Optionally, the second pushing member is a metal member, the component of the driving member used to fix the second pushing member is a plastic member, a welding metal is embedded in the plastic member at a position corresponding to the second pushing member, and the welding metal is fixed to the second pushing member by laser welding.

[0025] When the second pushing member is a metal member and the component used to fix the driving member to the second pushing member is a plastic member, the driving member and the second pushing member can be fixed together by laser welding by embedding welding metal in the position of the plastic member corresponding to the second pushing member. This fixing method can make the driving member very stably fixed on the second pushing member, thereby preventing the driving member from falling off the second pushing member.

[0026] In addition, when the second pusher is a metal part, the second pusher can be made stronger, thereby making the entire anti-shake mechanism stronger. When the part of the driving member used to fix the second pusher is a plastic part, the weight of the driving member can be reduced to a certain extent, thereby making the entire anti-shake mechanism lighter.

[0027] Optionally, the second pushing member is a circular ring structure, and two opposite surfaces of the second pushing member are respectively connected to the second connecting portion and the driving member.

[0028] When the second pushing member is a circular ring structure, since the circular ring structure can avoid excessive stress concentration to a certain extent, local deformation or breakage of the second pushing member can be avoided, so that the strength of the second pushing member is higher, and the strength of the entire anti-shake mechanism is further increased.

[0029] Optionally, the ring width of the first pushing member is greater than the ring width of the second pushing member.

[0030] The inventors have found through research that when the ring width of the first pushing member is greater than the ring width of the second pushing member, the strength of the anti-shake mechanism can be further enhanced and deformation is less likely to occur.

[0031] Optionally, the inner annular wall of the second pushing member forms a second light passing hole, and the axis of the second light passing hole coincides with the axis of the first light passing hole.

[0032] By making the axis of the second light hole coincide with the axis of the first light hole, on the one hand, the second light hole can be prevented from being misaligned with the first light hole, which is more conducive to the light passing through the second light hole smoothly after passing through the first light hole. On the other hand, the structure of the entire anti-shake mechanism can be made more regular and beautiful, and it can also avoid the situation that the various positions of the second pusher or the various positions of the first pusher are subjected to uneven force to a certain extent, thereby avoiding the situation that the local position of the second pusher or the local position of the first pusher is deformed, and then the strength of the anti-shake mechanism can be made higher.

[0033] Optionally, the connecting members are evenly spaced and arranged on an outer edge of the first pushing member.

[0034] When the connecting members are evenly spaced at the outer edge of the first pushing member, the multiple connecting members can evenly support the first pushing member at various positions of the first pushing member, so that the force at various positions of the first pushing member is relatively uniform, thereby making the first pushing member less likely to deform.

[0035] Optionally, a mounting portion is provided on the outer ring wall of the second pushing member, the mounting portion extends in a direction away from the axis of the first light passing hole, and the mounting portion is connected to the driving member.

[0036] By providing a mounting portion and extending the mounting portion in a direction away from the axis of the first light hole, when the distance between the side of the driving member away from the axis of the first light hole and the inner ring wall of the second pushing member is constant, the ring width of the second pushing member can be made narrower, thereby making the entire second pushing member lighter, saving material for the second pushing member, and reducing costs.

[0037] Optionally, there are multiple mounting parts, and the multiple mounting parts are arranged in a one-to-one correspondence with the multiple connecting members;

[0038] There are multiple driving members, and the multiple driving members correspond to the multiple mounting parts one by one, and the mounting parts are connected to the corresponding driving members.

[0039] That is to say, the mounting part, the connecting part and the driving part are arranged in a one-to-one correspondence. Since the driving part is used to drive the corresponding mounting part to move in a direction parallel to the axis of the first light hole, by arranging the mounting part, the connecting part and the driving part in a one-to-one correspondence, the connecting part can better withstand the force from the driving part, thereby avoiding deformation of the anti-shake mechanism.

[0040] Optionally, a pre-positioning structure is provided between the mounting portion and the driving member.

[0041] By providing a pre-positioning structure between the mounting portion and the driving member, on the one hand, the mounting accuracy between the mounting portion and the driving member can be improved, and on the other hand, the mounting speed between the mounting portion and the driving member can also be improved.

[0042] Optionally, the pre-positioning structure includes a first positioning hole and a positioning column, the first positioning hole is arranged on one of the mounting portion and the driving member, and the positioning column is arranged on the other of the mounting portion and the driving member.

[0043] When installing the driver on the mounting portion, the positioning column can be inserted into the first positioning hole to achieve pre-positioning, and then the driver can be installed on the mounting portion by glue fixation or laser welding fixation. Since the method of pre-positioning through the first positioning hole and the positioning column is simple in structure and mature in technology, the design cost and manufacturing cost of the pre-positioning structure can be reduced to a certain extent.

[0044] Optionally, the first positioning hole is arranged on the mounting portion, the positioning column is arranged on the driving member, and a notch is arranged on the mounting portion, the notch passes through the mounting portion from the first positioning hole in a direction away from the axis of the first light hole, and the width of the notch is greater than or equal to the diameter of the positioning column.

[0045] By setting a notch on the mounting portion, and making the notch pass through the mounting portion from the first positioning hole in the direction away from the axis of the first light hole, and the width of the notch is greater than or equal to the diameter of the positioning column, when the positioning column is inserted into the first positioning hole, it can be directly inserted into the first positioning hole through the notch, which is more convenient and quick.

[0046] By making the width of the notch greater than or equal to the diameter of the positioning post, the notch can avoid interference with the positioning post when the positioning post enters the first positioning hole through the notch, thereby making it smoother for the positioning post to enter the first positioning hole through the notch.

[0047] Optionally, the driving member comprises:

[0048] an anti-shake movable portion, the anti-shake movable portion being connected to an end of the first connecting portion away from the first pushing member;

[0049] An anti-shake circuit board, wherein the anti-shake circuit board is arranged on the anti-shake active part;

[0050] an anti-shake coil, wherein the anti-shake coil is arranged on the anti-shake circuit board; and

[0051] Magnetic parts;

[0052] The anti-shake coil is located in the magnetic field of the magnetic component, and the anti-shake coil is electrically connected to the anti-shake circuit board. The anti-shake circuit board is used to control the size, direction and on-off of the current in the anti-shake coil to drive the anti-shake coil to move, thereby changing the tilt angle of the liquid lens.

[0053] When image stabilization is performed, since the image stabilization coil is electrically connected to the image stabilization circuit board, the size, direction and on-off of the current in the image stabilization coil can be controlled by the image stabilization circuit board. Since the image stabilization coil is located in the magnetic field of the magnetic part, according to the left-hand rule, when there is current in the image stabilization coil, the magnetic field can cause the image stabilization coil to be subjected to the Ampere force. After the image stabilization coil is subjected to the Ampere force, the Ampere force can drive the image stabilization coil to move. Since the image stabilization coil is arranged on the image stabilization circuit board, and the image stabilization circuit board is arranged on the image stabilization active part, when the image stabilization coil moves, it can drive the image stabilization active part to move, and then the tilt angle of the liquid lens can be changed, thereby realizing the image stabilization function.

[0054] By placing the anti-shake coil in the magnetic field of the magnetic part and then controlling the size, direction and on-off of the current in the anti-shake coil through the anti-shake circuit board, the stress condition of the anti-shake coil can be conveniently adjusted. The technology is mature and the structural design is very ingenious, making the reliability of the anti-shake mechanism higher.

[0055] Optionally, the driving member comprises:

[0056] an anti-shake movable portion, the anti-shake movable portion being connected to an end of the first connecting portion away from the first pushing member;

[0057] A magnetic member, wherein the magnetic member is arranged on the anti-shake movable part;

[0058] An anti-shake circuit board and an anti-shake coil, wherein the anti-shake coil is arranged on the anti-shake circuit board;

[0059] The anti-shake coil is located in the magnetic field of the magnetic component. The anti-shake coil is electrically connected to the anti-shake circuit board. The anti-shake circuit board is used to control the size, direction and on-off of the current in the anti-shake coil to drive the magnetic component to move, thereby changing the tilt angle of the liquid lens.

[0060] When anti-shake is performed, since the magnetic part is arranged on the anti-shake active part, when there is current in the anti-shake coil, the magnetic part can be acted upon by force, driving the anti-shake active part to move, and then the tilt angle of the liquid lens can be changed, thereby realizing the anti-shake function.

[0061] In this embodiment, since the magnetic component is disposed on the anti-shake movable part and the magnetic component does not need to be connected to the circuit, when the magnetic component drives the anti-shake movable part to move, there will be no problem of circuit entanglement. Optionally, a support portion is disposed on a side of the anti-shake movable part close to the anti-shake circuit board, the support portion protrudes from the anti-shake movable part, a second positioning hole matching the support portion is disposed on the anti-shake circuit board, the anti-shake coil has a third positioning hole matching the support portion, and the support portion is sequentially inserted into the second positioning hole and the third positioning hole.

[0062] By inserting the support part into the second positioning hole and the third positioning hole in sequence, the anti-shake circuit board and the anti-shake coil can be pre-positioned respectively through the support part. On the one hand, the installation accuracy of the anti-shake circuit board and the anti-shake coil when they are installed on the anti-shake active part can be higher. On the other hand, the installation efficiency can be improved to a certain extent.

[0063] In addition, by inserting the supporting part into the second positioning hole of the anti-shake circuit board and the third positioning hole of the anti-shake coil in sequence, the anti-shake circuit board can be clamped between the anti-shake active part and the anti-shake coil. In this way, the anti-shake circuit board can be protected by the anti-shake active part and the anti-shake coil, thereby preventing the anti-shake circuit board from being scratched by other components.

[0064] Optionally, a wire hole or a wire groove is provided on the anti-shake circuit board.

[0065] By providing a wire groove or a wire hole, the wire in the anti-shake coil can pass through the wire groove or the wire hole to reach the side where the anti-shake active part is located, which provides convenience for the layout and routing of subsequent wires.

[0066] Optionally, the driving member further includes:

[0067] A spring sheet, wherein a first end of the spring sheet is fixedly arranged and a second end is connected to the anti-shake movable part, and an avoidance groove is arranged on the anti-shake movable part at a position corresponding to the spring sheet.

[0068] Based on the above description, it can be known that the anti-shake movable part can move in a direction parallel to the axis of the first light hole. Therefore, when the anti-shake movable part moves in a direction parallel to the axis of the first light hole, the spring piece can be deformed and move along with the anti-shake movable part. Based on this, an avoidance groove is provided at the position of the spring piece corresponding to the anti-shake movable part, so that a deformation space can be provided for the spring piece. In this way, on the one hand, a collision between the spring piece and the anti-shake movable part can be avoided, which may cause the anti-shake movable part to be scratched by the spring piece. On the other hand, a collision noise between the spring piece and the anti-shake movable part can be avoided.

[0069] Optionally, the anti-shake movable part has a third positioning part, the second end of the spring sheet is provided with a fourth positioning part matching the third positioning part, and the third positioning part matches the fourth positioning part to form a pre-positioning between the spring sheet and the anti-shake movable part.

[0070] When installing the spring piece on the anti-shake active part, the fourth positioning part on the spring piece can be matched with the third positioning part on the anti-shake active part to form a pre-positioning. After that, the spring piece and the anti-shake active part can be fixed together by gluing or laser welding. In this way, the installation position of the spring piece on the anti-shake active part can be more precise and the installation process can be more convenient.

[0071] Optionally, anti-collision chamfers are formed on at least part of the edges of the anti-shake movable portion.

[0072] By setting the anti-collision chamfer, it is possible to avoid, to a certain extent, the anti-shake movable part from hitting other components or the anti-shake movable part itself being hit by other components, making the entire anti-shake mechanism stronger and more durable.

[0073] On the other hand, the present application discloses a camera module, the camera module comprising:

[0074] Liquid lens;

[0075] In any one of the above aspects, the anti-shake mechanism comprises a first pushing member, the first pushing member comprises a first light-passing hole, and the liquid lens is disposed at the first light-passing hole.

[0076] Since the anti-shake mechanism can make the liquid lens swing more evenly, based on this, when the anti-shake mechanism is applied to a camera module, the anti-shake effect of the camera module can be improved.

[0077] On the other hand, the present application discloses an electronic device, which includes the camera module described in the other aspect above.

[0078] Since the camera module has a better anti-shake effect, when an electronic device includes a camera module, the anti-shake effect of the electronic device can be better.

[0079] Compared with the prior art, the beneficial effects of this application are:

[0080] When anti-shake is performed, since the driving member is connected to the first connecting part, when the driving member moves, the first connecting part can be driven to move. When the first connecting part moves, since the first connecting part is connected to the first pushing member, the first pushing member can be moved. At this time, since the first pushing member includes a first light hole and the liquid lens is arranged at the first light hole, when the first pushing member moves, the liquid lens can be driven to swing, thereby changing the inclination angle of the liquid lens. Based on this, when the anti-shake mechanism is applied to a camera module, after the inclination angle of the liquid lens changes, the angle, position, etc. of the light entering the camera module through the first light hole and the liquid lens can be changed, thereby enabling the camera module to achieve an anti-shake function.

[0081] Among them, when achieving the purpose of driving the liquid lens to swing, since the liquid lens is arranged at the first light hole of the first pusher, the purpose of driving the liquid lens to swing can be achieved by making the first pusher swing, and the swing of the first pusher is achieved by the driving member driving the first connecting part to move. In this way, the driving force of the driving member will be transmitted to the first pushing member through the first connecting part. In other words, the driving force of the driving member will not directly act on the first pushing member. The first connecting part can play a role in transmitting the driving force, and then can play a role in uniformly transmitting the driving force of the driving member to the first pushing member. When the driving force of the driving member can be uniformly transmitted to the first pushing member, the first pushing member can swing more evenly, and then the liquid lens can swing more evenly. Based on this, when the anti-shake mechanism is used in the camera module, the anti-shake effect of the camera module can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0107] Figure 1 is a structural schematic diagram of an anti-shake mechanism provided in an embodiment of the present application, Figure 2 yes Figure 1 Schematic diagram of the structure when the anti-shake mechanism in the liquid lens is connected, Figure 3 yes Figure 2Schematic diagram of the structure when the liquid lens and anti-shake mechanism are disassembled.

[0108] See also Figure 1 , Figure 2 and Figure 3 The anti-shake mechanism 100 is used to connect with the liquid lens 200, and the anti-shake mechanism 100 includes: a first pusher 11, a connecting member 12 and a driving member 13. Among them, the first pusher 11 includes a first light hole 111, and the liquid lens 200 is arranged at the first light hole 111. The connecting member 12 includes a first connecting portion 121 extending along the axis Z1 direction of the first light hole 111, one end of the first connecting portion 121 is connected to the outer edge of the first pusher 11, and the driving member 13 is connected to the end of the first connecting portion 121 away from the first pusher 11. The driving member 13 is used to drive the first connecting portion 121 to move, thereby driving the liquid lens 200 to swing to change the tilt angle a of the liquid lens 200.

[0109] In the embodiment of the present application, when anti-shake is performed, since the driving member 13 is connected to the first connecting portion 121, when the driving member 13 moves, the first connecting portion 121 can be driven to move. When the first connecting portion 121 moves, since the first connecting portion 121 is connected to the first pushing member 11, the first pushing member 11 can be moved. At this time, since the first pushing member 11 includes the first light hole 111, the liquid lens 200 is arranged at the first light hole 111, therefore, when the first pushing member 11 moves, the liquid lens 200 can be driven to swing, and then the tilt angle a of the liquid lens 200 can be changed. Based on this, when the anti-shake mechanism 100 is applied to the camera module, after the tilt angle a of the liquid lens 200 changes, the angle, position, etc. of the light entering the camera module through the first light hole 111 and the liquid lens 200 can be changed, and then the camera module can achieve the anti-shake function.

[0110] Among them, when achieving the purpose of driving the liquid lens to swing, since the liquid lens is arranged at the first light hole 111 of the first pusher 11, the purpose of driving the liquid lens to swing can be achieved by making the first pusher 11 swing, and the swing of the first pusher 11 is achieved by the driving member 13 driving the first connecting part 121 to move, so that the driving force of the driving member 13 will be transmitted to the first pusher 11 through the first connecting part 121. In other words, the driving force of the driving member 13 will not directly act on the first pusher 11. The first connecting part 121 can play a role in transmitting the driving force, and then can play a role in uniformly transmitting the driving force of the driving member 13 to the first pusher 11. When the driving force of the driving member 13 can be uniformly transmitted to the first pusher 11, the first pusher 11 can swing more evenly, and then the liquid lens can swing more evenly. Based on this, when the anti-shake mechanism is used in the camera module, the anti-shake effect of the camera module can be improved.

[0111] The tilt angle a is the angle between the plane M1 where the liquid lens 200 is located and the reference plane M2, where the reference plane M2 may be a horizontal plane. The plane M1 where the liquid lens 200 is located is the plane where one side of the liquid lens 200 connected to the first pusher 11 is located.

[0112] For example, see Figure 4 , assuming that in the initial state, the plane M1 where the liquid lens 200 is located is parallel to the reference plane M2, then the tilt angle a is 0°. Figure 5 Assuming that the first pusher 11 drives the liquid lens 200 to swing 15°, the tilt angle a is 15°.

[0113] When the tilt angle a of the liquid lens 200 changes, the liquid lens 200 can change the angle, position, etc. of the light passing through the liquid lens 200 and entering the camera module, thereby realizing the anti-shake function based on this principle.

[0114] It should be noted that the above-mentioned liquid lens 200 can be arranged at the first light hole 111 of the first pusher 11 by means of glue bonding. When the liquid lens 200 is arranged at the first light hole 111 of the first pusher 11 by means of glue bonding, as the first pusher 11 swings, the partial structure of the liquid lens 200 bonded to the first pusher 11 can swing along with the first pusher 11, thereby changing the tilt angle of the liquid lens 200, thereby achieving the anti-shake function. Of course, it can also be arranged at the first light hole 111 of the first pusher 11 by other means. For example, it is also possible to make the liquid lens 200 only contact with the first light hole 111 of the first pusher 11, so that when the first pusher 11 swings, the first pusher 11 can squeeze the liquid lens 200, so that the shape of the liquid lens 200 changes, and in this way, the tilt angle of the liquid lens 200 can also change, thereby achieving the purpose of anti-shake. That is, it is only necessary to dispose the liquid lens 200 at the first light-passing hole 111 of the first pusher 11 , and this embodiment of the present application does not limit this.

[0115] In some embodiments, see Figure 2 The connecting member 12 further includes a second connecting portion 122, a first end of the second connecting portion 122 is connected to an end of the first connecting portion 121 away from the first pushing member 11, and a second end of the second connecting portion 122 is directed away from the axis Z1 of the first light hole 111 (i.e. Figure 2 The driving member 13 is connected to the second end of the second connecting portion 122.

[0116] In this embodiment, when anti-shake is performed, since the driving member 13 is connected to the second connecting portion 122, when the driving member 13 moves, the second connecting portion 122 can be driven to move. When the second connecting portion 122 moves, since the first connecting portion 121 is respectively connected to the second connecting portion 122 and the first pushing member 11, the first pushing member 11 can be moved, and then the liquid lens can be driven to swing, thereby realizing the anti-shake function.

[0117] Among them, see Figure 4 Since the first connection portion 121 is along the axis Z1 direction of the first light hole 111 (ie Figure 4The first connecting portion 121 extends in the Z direction (in the middle Z direction), one end of the first connecting portion 121 is connected to the outer edge of the first pushing member 11, the first end of the second connecting portion 122 is connected to the end of the first connecting portion 121 away from the first pushing member 11, and the second end of the second connecting portion 122 extends in the direction away from the axis Z1 of the first light hole 111. Therefore, the first pushing member 11, the first connecting portion 121 and the second connecting portion 122 can jointly form a "staircase" structure. When the first pushing member 11, the first connecting portion 121 and the second connecting portion 122 jointly form a "staircase" structure, an empty space K can be formed between the first connecting portion 121 and the second connecting portion 122. In this way, the volume occupied by the connecting member 12 can be made smaller, thereby making the volume of the anti-shake mechanism 100 more compact. At the same time, the above-mentioned empty space K can be vacated to place other components, thereby making the entire anti-shake mechanism 100 more compact.

[0118] It should be noted that the first pushing member 11 , the first connecting portion 121 and the second connecting portion 122 may be an integrated structure or a split structure, which is not limited in the embodiment of the present application.

[0119] Further, see Figure 2 In some embodiments, one end of the first connection portion 121 is connected to the outer edge of the first pushing member 11 through the third connection portion 123 , and the third connection portion 123 extends from the outer edge of the first pushing member 11 in a direction away from the axis Z1 of the first light hole 111 .

[0120] When one end of the first connection portion 121 is connected to the outer edge of the first pusher 11 through the third connection portion 123, and the third connection portion 123 extends from the outer edge of the first pusher 11 in a direction away from the axis Z1 of the first light hole 111, a first distance between one end of the second connection portion 122 away from the axis Z1 of the first light hole 111 and the outer edge of the first pusher 11 is equal to the length of the third connection portion 123 ( Figure 2 length in the X direction) and the length of the second connecting portion 122 ( Figure 2 That is to say, when the first distance remains unchanged, by providing the third connection portion 123, the length of the second connection portion 122 can be shortened. In this way, when the second connection portion 122 is subjected to the swing force from the driving member 13, the length of the second connection portion 122 is shortened. Therefore, the strength of the second connection portion 122 will be increased and it will not be easily deformed. Therefore, the strength of the entire anti-shake mechanism 100 can be increased and it will not be easily deformed.

[0121] The first pusher 11 is a circular ring structure, and the inner ring wall of the circular ring structure encloses the first light hole 111. By making the first pusher 11 a circular ring structure, since the circular ring structure is not prone to stress concentration, the first pusher 11 is not prone to deformation or fracture, and thus the strength of the entire anti-shake mechanism 100 can be higher.

[0122] Of course, the first pushing member 11 may also be a structure of other shapes. For example, the first pushing member 11 may also be a rectangular ring structure or a polygonal ring structure, etc., which is not limited in the embodiments of the present application.

[0123] In some embodiments, see Figure 2 , the number of connecting members 12 is multiple ( Figure 2 In the embodiment, the number of the connecting members 12 is 4, and the multiple connecting members 12 are arranged at intervals on the outer edge of the first pushing member 11. By making the number of the connecting members 12 multiple and making the multiple connecting members 12 arranged at intervals on the outer edge of the first pushing member 11, the multiple connecting members 12 can jointly support the first pushing member 11 at multiple different positions of the first pushing member 11, so that the first pushing member 11 is less likely to be deformed.

[0124] Further, in some embodiments, see Figure 2 , the connecting members 12 are evenly spaced at the outer edge of the first pushing member 11. When the connecting members 12 are evenly spaced at the outer edge of the first pushing member 11, the multiple connecting members 12 can evenly support the first pushing member 11 at various positions of the first pushing member 11, so that the force at various positions of the first pushing member 11 is relatively uniform, so that the first pushing member 11 is less likely to deform, and the arrangement of the multiple connecting members 12 can provide sufficient thrust to drive the first pushing member 11 to move.

[0125] It should be noted that the number of the connecting members 12 can be 2, 3, 4, 5, etc., which is not limited in the embodiment of the present application.

[0126] In some embodiments, see Figure 2 and Figure 3 , the first connecting portion 121 is an arc-shaped structure (ie: Figure 3 The cross section of the first connecting portion 121 parallel to the first pushing member 11 is in the shape of an arc, that is, Figure 3The cross section of the first connection portion 121 in the plane where the dotted line S is located is in an arc shape), and the axis of the arc-shaped structure is parallel to the axis Z1 of the first light hole 111. By making the first connection portion 121 an arc-shaped structure and making the axis of the arc-shaped structure parallel to the axis Z1 of the first light hole 111, the first connection portion 121 can be more capable of withstanding the force in the direction parallel to the axis Z1 of the first light hole 111, and thus the first connection portion 121 is not easily deformed, so that the strength of the entire anti-shake mechanism 100 can be higher.

[0127] In order to make the entire anti-shake mechanism 100 stronger, further, in some embodiments, see Figure 2 The anti-shake mechanism further includes a second pusher 14, and the plurality of second connection parts 122 are all connected to the driving member 13 through the second pusher 14. By connecting the second connection parts 122 to the second pusher 14, and then connecting the second pusher 14 to the driving member 13, the second pusher 14 can play a role in fixing the plurality of second connection parts 122 on itself, so that the positional relationship between the plurality of second connection parts 122 can be restrained by the second pusher 14, so that the plurality of second connection parts 122 form a whole, that is, the plurality of connection members 12 form a whole, so that the strength of the whole formed by the plurality of connection members 12 can be made stronger, and thus the strength of the entire anti-shake mechanism 100 can be made higher.

[0128] In some embodiments, see Figure 2 The second pusher 14 is a metal part, and the part of the driving member 13 used to fix the second pusher 14 is a plastic part. A welding metal is embedded in the position of the plastic part corresponding to the second pusher 14, and the welding metal and the second pusher 14 are fixed by laser welding.

[0129] When the second pushing member 14 is a metal member, and the component used to fix the driving member 13 to the second pushing member 14 is a plastic member, the driving member 13 and the second pushing member 14 can be fixed by laser welding by embedding welding metal in the position corresponding to the second pushing member 14 in the plastic member. This fixing method can make the driving member 13 very stably fixed on the second pushing member 14, thereby preventing the driving member 13 from falling off the second pushing member 14.

[0130] In addition, when the second pusher 14 is a metal part, the second pusher 14 can be made stronger, thereby making the entire anti-shake mechanism 100 stronger. When the part of the driving member 13 used to fix the second pusher 14 is a plastic part, the weight of the driving member 13 can be reduced to a certain extent, thereby making the entire anti-shake mechanism 100 lighter.

[0131] The welding metal may be iron, aluminum or other metals, and the present embodiment does not limit the welding metal. In addition, the metal parts may be iron parts, stainless steel parts or the like, and the present embodiment does not limit this.

[0132] In some embodiments, see Figure 2 The second pusher 14 is a circular ring structure, and the two opposite sides of the second pusher 14 are respectively connected to the second connection portion 122 and the driving member 13. When the second pusher 14 is a circular ring structure, since the circular ring structure can avoid the occurrence of excessive stress concentration to a certain extent, the local deformation or fracture of the second pusher 14 can be avoided, so that the strength of the second pusher 14 is higher, and then the strength of the entire anti-shake mechanism 100 is higher.

[0133] In order to further improve the strength of the entire anti-shake mechanism 100, further, in some embodiments, the ring width of the first pusher 11 is greater than the ring width of the second pusher 14. The inventors have found that when the ring width of the first pusher 11 is greater than the ring width of the second pusher 14, the strength of the anti-shake mechanism 100 can be further enhanced and less prone to deformation.

[0134] In some embodiments, see Figure 6 , the inner annular wall of the second pusher 14 forms a second light hole 140, and the axis of the second light hole 140 coincides with the axis Z1 of the first light hole 111. By making the axis of the second light hole 140 coincide with the axis Z1 of the first light hole 111, on the one hand, it is possible to avoid the second light hole 140 from being misaligned with the first light hole 111, which is more conducive to the light passing through the second light hole 140 smoothly after passing through the first light hole 111. On the other hand, the structure of the entire anti-shake mechanism 100 can be more regular and beautiful, and it can also avoid the situation that the various positions of the second pusher 14 or the various positions of the first pusher 11 are subjected to uneven force to a certain extent, thereby avoiding the situation that the local position of the second pusher 14 or the local position of the first pusher 11 is deformed, and the strength of the anti-shake mechanism 100 can be higher.

[0135] In some embodiments, see Figure 2The outer ring wall of the second pusher 14 has a mounting portion 141, which extends in a direction away from the axis Z1 of the first light hole 111, and is connected to the driving member 13. By providing the mounting portion 141 and extending the mounting portion 141 in a direction away from the axis Z1 of the first light hole 111, when the distance between the side of the driving member 13 away from the axis Z1 of the first light hole 111 and the inner ring wall of the second pusher 14 is constant, the ring width of the second pusher 14 can be made narrower, and the entire second pusher 14 can be made lighter, and the material of the second pusher 14 can be saved, thereby reducing the cost.

[0136] There may be a plurality of mounting parts 141, and the plurality of mounting parts 141 are arranged in one-to-one correspondence with the plurality of connecting members 12. There may be a plurality of driving members 13, and the plurality of driving members 13 are arranged in one-to-one correspondence with the plurality of mounting parts 141, and the mounting parts 141 are connected to the corresponding driving members 13. In other words, the mounting parts 141, the connecting members 12, and the driving members 13 are arranged in one-to-one correspondence, and since the driving members 13 are used to drive the corresponding mounting parts 141 to move in a direction parallel to the axis Z1 of the first light hole 111, therefore, by making the mounting parts 141, the connecting members 12, and the driving members 13 arranged in one-to-one correspondence, the connecting members 12 can better withstand the force from the driving members 13, thereby preventing the anti-shake mechanism 100 from being deformed.

[0137] In some embodiments, see Figure 2 A pre-positioning structure 15 is provided between the mounting portion 141 and the driving member 13. By providing the pre-positioning structure 15 between the mounting portion 141 and the driving member 13, on the one hand, the mounting accuracy between the mounting portion 141 and the driving member 13 can be improved. On the other hand, the mounting speed between the mounting portion 141 and the driving member 13 can also be improved.

[0138] Among them, see Figure 2 , the above-mentioned pre-positioning structure 15 may include a first positioning hole 151 and a positioning column 152, the first positioning hole 151 is arranged on the mounting portion 141, and the positioning column 152 is arranged on the driving member 13. In this way, when the driving member 13 is installed on the mounting portion 141, the positioning column 152 may be first inserted into the first positioning hole 151 to achieve pre-positioning, and then the driving member 13 may be installed on the mounting portion 141 by glue fixation or laser welding fixation. Since the method of pre-positioning through the first positioning hole 151 and the positioning column 152 is simple in structure and mature in technology, the design cost and manufacturing cost of the pre-positioning structure 15 can be reduced to a certain extent.

[0139] Of course, the first positioning hole 151 may also be set on the driving member 13 , and the positioning column 152 may be set on the mounting portion 141 , which is not limited in the embodiment of the present application.

[0140] In addition, the above-mentioned pre-positioning structure 15 including the first positioning hole 151 and the positioning column 152 is only a possible implementation form shown in the embodiment of the present application. In other embodiments, the pre-positioning structure 15 may also include other possible structures. For example, the pre-positioning structure 15 may include buckles and claws, etc., as long as it can achieve the purpose of pre-positioning between the driving member 13 and the mounting portion 141. The embodiment of the present application does not limit the pre-positioning structure 15.

[0141] Further, see Figure 2 The first positioning hole 151 is provided on the mounting portion 141, the positioning column 152 is provided on the driving member 13, and a notch 1411 is provided on the mounting portion 141. The notch 1411 penetrates the mounting portion 141 from the first positioning hole 151 in a direction away from the axis Z1 of the first light-passing hole 111, and the width of the notch 1411 is greater than or equal to the diameter of the positioning column 152. By providing the notch 1411 on the mounting portion 141, and making the notch 1411 penetrate the mounting portion 141 from the first positioning hole 151 in a direction away from the axis Z1 of the first light-passing hole 111, and making the width of the notch 1411 greater than or equal to the diameter of the positioning column 152, when the positioning column 152 is inserted into the first positioning hole 151, it can be directly inserted into the first positioning hole 151 from the notch 1411, which is more convenient and quick.

[0142] By making the width of the notch 1411 greater than or equal to the diameter of the positioning column 152, the notch 1411 can avoid interference with the positioning column 152 when the positioning column 152 enters the first positioning hole 151 through the notch 1411, thereby making the positioning column 152 enter the first positioning hole 151 more smoothly through the notch 1411.

[0143] In some embodiments, see Figure 2 and Figure 7 The driving member 13 includes: an anti-shake movable part 131, an anti-shake circuit board 132, an anti-shake coil 133 and a magnetic member 134. The anti-shake movable part 131 is connected to the end of the first connecting part 121 away from the first pushing member 11, the anti-shake circuit board 132 is arranged on the anti-shake movable part 131, the anti-shake coil 133 is arranged on the anti-shake circuit board 132, the anti-shake coil 133 is located in the magnetic field of the magnetic member 134, the anti-shake coil 133 is electrically connected to the anti-shake circuit board 132, and the anti-shake circuit board 132 is used to control the magnitude, direction and on-off of the current in the anti-shake coil 133, so as to drive the anti-shake coil 133 to move through the magnetic field, so as to change the tilt angle of the liquid lens 200.

[0144] In this embodiment, when anti-shake is performed, since the anti-shake coil 133 is electrically connected to the anti-shake circuit board 132, the size, direction and on-off of the current in the anti-shake coil 133 can be controlled by the anti-shake circuit board 132. Since the anti-shake coil 133 is located in the magnetic field of the magnetic part 134, according to the left-hand rule, when there is current in the anti-shake coil 133, the magnetic field can cause the anti-shake coil 133 to be subjected to the Ampere force. After the anti-shake coil 133 is subjected to the Ampere force, the Ampere force can drive the anti-shake coil 133 to move. Since the anti-shake coil 133 is arranged on the anti-shake circuit board 132, and the anti-shake circuit board 132 is arranged on the anti-shake active part 131, when the anti-shake coil 133 moves, it can drive the anti-shake active part 131 to move, and then the tilt angle of the liquid lens 200 can be changed, thereby realizing the anti-shake function.

[0145] By placing the anti-shake coil 133 in the magnetic field of the magnetic part 134 and then controlling the magnitude, direction and on-off of the current in the anti-shake coil 133 through the anti-shake circuit board 132, the stress condition of the anti-shake coil 133 can be conveniently adjusted. The technology is mature and the structural design is very clever, making the reliability of the anti-shake mechanism 100 higher.

[0146] In other embodiments, the driving member 13 includes: an anti-shake movable part 131, an anti-shake circuit board 132, an anti-shake coil 133 and a magnetic member 134. The anti-shake movable part 131 is connected to the end of the first connecting part 121 away from the first pushing member 11, the magnetic member 134 is arranged on the anti-shake movable part 131, and the anti-shake coil 133 is arranged on the anti-shake circuit board 132. The anti-shake coil 133 is located in the magnetic field of the magnetic member 134, and the anti-shake coil 133 is electrically connected to the anti-shake circuit board 132. The anti-shake circuit board 132 is used to control the magnitude, direction and on-off of the current in the anti-shake coil 133 to drive the magnetic member 134 to move, thereby changing the tilt angle of the liquid lens.

[0147] In this embodiment, when anti-shake is performed, since the magnetic member 134 is arranged on the anti-shake movable part 131, when there is current in the anti-shake coil 133, the magnetic member 134 can be acted upon by force, driving the anti-shake movable part 131 to move, thereby changing the tilt angle of the liquid lens 200, thereby realizing the anti-shake function.

[0148] In this embodiment, since the magnetic member 134 is disposed on the anti-shake movable portion 131 and the magnetic member does not need to be connected to a circuit, when the magnetic member 134 drives the anti-shake movable portion 131 to move, there will be no problem of circuit entanglement.

[0149] It should be noted that the magnetic component 134 may be a magnet or a magnet, etc., and it only needs to be able to provide a magnetic field for the anti-shake coil 133 . The embodiment of the present application does not limit the magnetic component 134 .

[0150] In some embodiments, see Figure 7 A supporting portion 1311 is provided on one side of the anti-shake active portion 131 close to the anti-shake circuit board 132, and the supporting portion 1311 protrudes out of the anti-shake active portion 131. A second positioning hole 1321 matching the supporting portion 1311 is provided on the anti-shake circuit board 132, and the anti-shake coil 133 has a third positioning hole 1331 matching the supporting portion 1311, and the supporting portion 1311 is inserted into the second positioning hole 1321 and the third positioning hole 1331 in sequence.

[0151] By inserting the support part 1311 into the second positioning hole 1321 and the third positioning hole 1331 in sequence, the anti-shake circuit board 132 and the anti-shake coil 133 can be pre-positioned respectively through the support part 1311. On the one hand, the installation accuracy of the anti-shake circuit board 132 and the anti-shake coil 133 when they are installed on the anti-shake active part 131 can be higher. On the other hand, the installation efficiency can also be improved to a certain extent.

[0152] In addition, by inserting the support part 1311 into the second positioning hole 1321 of the anti-shake circuit board 132 and the third positioning hole 1331 of the anti-shake coil 133 in sequence, the anti-shake circuit board 132 can be clamped between the anti-shake active part 131 and the anti-shake coil 133. In this way, the anti-shake circuit board 132 can be protected by the anti-shake active part 131 and the anti-shake coil 133, thereby preventing the anti-shake circuit board 132 from being scratched by other components.

[0153] The number of the support parts 1311 may be 1, 2 or any other possible number, which is not limited in the embodiment of the present application.

[0154] Furthermore, in some embodiments, the driving member 13 may also include a driving module and a capacitor, and the driving module and the capacitor are both electrically connected to the anti-shake circuit board 132 and are both accommodated in the third positioning hole 1331. In this way, in addition to pre-positioning the positional relationship between the anti-shake coil 133 and the anti-shake active part 131, the third positioning hole 1331 can also be used to accommodate the driving module and the capacitor, which is a multi-purpose and very clever structural design. In addition, by accommodating the driving module and the capacitor in the third positioning hole 1331, the space in the third positioning hole 1331 can be fully utilized, thereby making the entire anti-shake mechanism 100 more compact.

[0155] The driving module may be a driving chip for controlling the current size, on-off, etc. in the anti-shake coil 133, which is not limited in the embodiment of the present application. By setting the capacitor, the circuit in the anti-shake circuit board 132 can be operated more stably.

[0156] In some embodiments, see Figure 7 A wire groove 1322 is provided on the anti-shake circuit board 132. By providing the wire groove 1322, the line in the anti-shake coil 133 can pass through the wire groove 1322 to reach the side where the anti-shake active part 131 is located, which facilitates the layout and routing of subsequent lines.

[0157] Among them, the number of the wire grooves 1322 can be 1, 2, or 3, etc., and can be arbitrarily set according to actual needs. The embodiment of the present application does not limit the number of the wire grooves 1322.

[0158] Of course, the anti-shake circuit board 132 may also be provided with a wire hole, or the anti-shake circuit board 132 may be provided with both a wire hole and a wire groove 1322 , as long as it can facilitate the layout and routing of subsequent lines. This application embodiment of our company does not limit this.

[0159] In some embodiments, see Figure 8 The driving member 13 further includes: a spring piece 135 , a first end of which is fixedly arranged, and a second end of which is connected to the anti-shake movable part 131 , and an avoidance groove 1312 is arranged at a position of the anti-shake movable part 131 corresponding to the spring piece 135 . Based on the above description, it can be known that the anti-shake movable part 131 can move in a direction parallel to the axis Z1 of the first light hole 111. Therefore, when the anti-shake movable part 131 moves in a direction parallel to the axis Z1 of the first light hole 111, the spring piece 135 can be deformed and move along with the anti-shake movable part 131. Based on this, by setting an avoidance groove 1312 at the position of the anti-shake movable part 131 corresponding to the spring piece 135, a deformation space can be provided for the spring piece 135. In this way, on the one hand, a collision between the spring piece 135 and the anti-shake movable part 131 can be avoided, which may cause the anti-shake movable part 131 to be scratched by the spring piece 135. On the other hand, a collision noise between the spring piece 135 and the anti-shake movable part 131 can also be avoided.

[0160] In order to make the installation position more accurate and the installation process more convenient when the spring piece 135 is installed on the anti-shake active part 131, in some embodiments, see Figure 8, the anti-shake movable part 131 has a third positioning part 1313, and the second end of the spring piece 135 is provided with a fourth positioning part 1351 matching the third positioning part 1313, and the third positioning part 1313 matches the fourth positioning part 1351 to form a pre-positioning between the spring piece 135 and the anti-shake movable part 131. In this way, when the spring piece 135 is installed on the anti-shake movable part 131, the fourth positioning part 1351 on the spring piece 135 can be matched with the third positioning part 1313 on the anti-shake movable part 131 to form a pre-positioning, and then the spring piece 135 and the anti-shake movable part 131 are fixed by glue bonding or laser welding. In this way, the installation position of the spring piece 135 when it is installed on the anti-shake movable part 131 can be more accurate and the installation process can be more convenient.

[0161] Among them, one of the third positioning portion 1313 and the fourth positioning portion 1351 can be a positioning hole, and the other can be a positioning column. Of course, the third positioning portion 1313 and the fourth positioning portion 1351 can also be other possible structures. For example, in some embodiments, see Figure 8 , the fourth positioning portion 1351 can be a substantially "L"-shaped claw structure, and the third positioning portion 1313 can be a rectangular bump structure. By making the two inner walls of the "L"-shaped claw structure simultaneously fit with the two adjacent vertical surfaces of the rectangular bump structure, the spring sheet 135 and the anti-shake movable portion 131 can be pre-positioned. In other words, as long as the spring sheet 135 and the anti-shake movable portion 131 can be pre-positioned, the third positioning portion 1313 and the fourth positioning portion 1351 are not limited in the embodiment of the present application.

[0162] In order to prevent the anti-shake movable part 131 from colliding with other parts when moving in a direction parallel to the axis Z1 of the first light hole 111, causing other parts or the anti-shake movable part 131 itself to be damaged, in some embodiments, see Figure 8 At least part of the edges of the anti-shake movable part 131 are formed with anti-collision chamfers 1314. By providing the anti-collision chamfers 1314, it is possible to prevent the anti-shake movable part 131 from hitting other parts or the anti-shake movable part 131 itself from being hit by other parts to a certain extent, making the entire anti-shake mechanism 100 more solid and durable.

[0163] In summary, in the embodiment of the present application, when anti-shake is performed, since the driving member 13 is connected to the first connecting portion 121, when the driving member 13 moves, the first connecting portion 121 can be driven to move. When the first connecting portion 121 moves, since the first connecting portion 121 is connected to the first pushing member 11, the first pushing member 11 can be moved. At this time, since the first pushing member 11 includes the first light hole 111, the liquid lens 200 is arranged at the first light hole 111, therefore, when the first pushing member 11 moves, the liquid lens 200 can be driven to swing, and then the tilt angle a of the liquid lens 200 can be changed. Based on this, when the anti-shake mechanism 100 is applied to the camera module, after the tilt angle a of the liquid lens 200 changes, the angle, position, etc. of the light entering the camera module through the first light hole 111 and the liquid lens 200 can be changed, and then the camera module can achieve the anti-shake function.

[0164] Among them, when achieving the purpose of driving the liquid lens to swing, since the liquid lens is arranged at the first light hole 111 of the first pusher 11, the purpose of driving the liquid lens to swing can be achieved by making the first pusher 11 swing, and the swing of the first pusher 11 is achieved by the driving member 13 driving the first connecting part 121 to move, so that the driving force of the driving member 13 will be transmitted to the first pusher 11 through the first connecting part 121. In other words, the driving force of the driving member 13 will not directly act on the first pusher 11. The first connecting part 121 can play a role in transmitting the driving force, and then can play a role in uniformly transmitting the driving force of the driving member 13 to the first pusher 11. When the driving force of the driving member 13 can be uniformly transmitted to the first pusher 11, the first pusher 11 can swing more evenly, and then the liquid lens can swing more evenly. Based on this, when the anti-shake mechanism is used in the camera module, the anti-shake effect of the camera module can be improved.

[0165] In addition, it can be seen from the above description that since the anti-shake function is achieved by the anti-shake mechanism 100 driving the liquid lens 200 to swing, it can be understood that the liquid lens 200 is light in weight, and the anti-shake mechanism 100 needs to provide a smaller force to make the liquid lens 200 swing. Therefore, the anti-shake mechanism 100 in the embodiment of the present application does not need to be designed to be as strong and bulky as the anti-shake mechanism 100 in the related art. In other words, the anti-shake mechanism 100 in the embodiment of the present application can be designed to be small and light, thereby making the entire camera module small and light.

[0166] In addition, since the first connecting portion 121 is along the axis Z1 direction of the first light hole 111 (ie Figure 4The first connecting portion 121 extends in the middle Z direction, one end of the first connecting portion 121 is connected to the outer edge of the first pushing member 11, and the other end of the first connecting portion 121 extends in the direction away from the axis Z1 of the first light hole 111 to form the second connecting portion 122. Therefore, the first pushing member 11, the first connecting portion 121 and the second connecting portion 122 can form a "staircase" structure together. When the first pushing member 11, the first connecting portion 121 and the second connecting portion 122 form a "staircase" structure together, an empty space K can be formed between the first connecting portion 121 and the second connecting portion 122. In this way, the volume occupied by the connecting member 12 can be made smaller, and the volume of the anti-shake mechanism 100 can be made more compact. At the same time, the above-mentioned empty space K can be vacated to place other components, and the entire anti-shake mechanism 100 can be further compact.

Fig. 9 The camera module includes: a liquid lens 200 and an anti-shake mechanism 100 , the anti-shake mechanism 100 includes a first pusher 11 , the first pusher 11 includes a first light hole 111 , and the liquid lens 200 is disposed at the first light hole 111 .

[0168] Among them, the anti-shake mechanism 100 can have the same structure as the anti-shake mechanism 100 in any of the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0169] In the embodiment of the present application, when anti-shake is performed, light can enter the camera module through the liquid lens 200 and the first light hole 111 in sequence. Since the anti-shake mechanism 100 can drive the liquid lens 200 to swing to change the tilt angle a of the liquid lens 200, when the tilt angle a of the liquid lens 200 changes, the angle, position, etc. of the light entering the camera module can be changed, thereby enabling the camera module to achieve an anti-shake function.

[0170] Among them, since the anti-shake mechanism 100 can make the liquid lens swing more evenly, based on this, when the anti-shake mechanism is applied to a camera module, the anti-shake effect of the camera module can be improved.

Please refer to the description in the above embodiment for details, and the embodiments of the present application will not be repeated here.

[0173] In the embodiment of the present application, since the camera module 300 has a better anti-shake effect, when an electronic device includes the camera module 300, the anti-shake effect of the electronic device can be better.
