Wherein, the inclination angle a is: the reference plane M2 may be a horizontal plane, which is an angle between the plane M1 where the liquid lens 200 is located and the reference plane M2. The plane M1 of the liquid lens 200 is a plane of a surface of the liquid lens 200 connected to the first pushing member 11.

For example, referring to fig. 4, assuming that in the initial state, the plane M1 of the liquid lens 200 is parallel to the reference plane M2, the inclination angle a is 0 °. Referring to fig. 5, if the first pushing element 11 drives the liquid lens 200 to swing by 15 °, the inclination angle a is 15 °.

When the inclination 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 and entering the camera module, and then the anti-shake function can be realized according to the principle.

It should be noted that the liquid lens 200 may be disposed at the first light passing hole 111 of the first pushing member 11 in a glue bonding manner, and when the liquid lens 200 is disposed at the first light passing hole 111 of the first pushing member 11 in a glue bonding manner, along with the swing of the first pushing member 11, a part of the structure where the liquid lens 200 and the first pushing member 11 are bonded may swing together with the first pushing member 11, so that the inclination angle of the liquid lens 200 may be changed, and thus the anti-shake function may be implemented. Of course, the light-passing hole 111 of the first pushing member 11 may be provided in other manners. For example, the liquid lens 200 may only contact with the first light passing hole 111 of the first pushing element 11, so that when the first pushing element 11 swings, the first pushing element 11 may push the liquid lens 200, so that the shape of the liquid lens 200 changes, and thus, the inclination angle of the liquid lens 200 may also change, and the anti-shake purpose may be further achieved. That is, the liquid lens 200 only needs to be disposed at the first light passing hole 111 of the first pushing member 11, which is not limited in the embodiment of the present application.

In some embodiments, referring to fig. 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 far away from the first pushing member 11, a second end of the second connecting portion 122 extends in a direction far away from the axis Z1 of the first lighting hole 111 (i.e., in a direction spreading from the axis Z1 to the periphery in fig. 2), and the driving member 13 is connected to a second end of the second connecting portion 122.

In this embodiment, during anti-shake, since the driving element 13 is connected to the second connecting portion 122, when the driving element 13 moves, the second connecting portion 122 can be driven to move, and when the second connecting portion 122 moves, since the first connecting portion 121 is connected to the second connecting portion 122 and the first pushing element 11, respectively, the first pushing element 11 can move, and thus the liquid lens can be driven to swing, so as to achieve the anti-shake function.

Referring to fig. 4, since the first connecting portion 121 extends along the axis Z1 direction of the first light passing hole 111 (i.e. the Z direction in fig. 4), 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 far away from the first pushing member 11, and the second end of the second connecting portion 122 extends towards the direction far away from the axis Z1 of the first light passing hole 111, the first pushing member 11, the first connecting portion 121, and the second connecting portion 122 may form a "step" structure together. When the first pushing member 11, the first connecting portion 121 and the second connecting portion 122 form a "ladder" structure together, a vacant space K can be formed between the first connecting portion 121 and the second connecting portion 122, so that the occupied size of the connecting member 12 is small, and the size of the anti-shake mechanism 100 is small, and meanwhile, the vacant space K can be freed to place other components, and the whole anti-shake mechanism 100 can further become small.

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

When one end of the first connecting portion 121 is connected to the outer edge of the first pushing member 11 through the third connecting portion 123, and the third connecting portion 123 extends from the outer edge of the first pushing member 11 toward the direction away from the axis Z1 of the first light passing hole 111, a first distance between one end of the second connecting portion 122 away from the axis Z1 of the first light passing hole 111 and the outer edge of the first pushing member 11 is equal to the sum of the length of the third connecting portion 123 (the length in the X direction in fig. 2) and the length of the second connecting portion 122 (the length in the X direction in fig. 2), that is, in the case that the first distance is not changed, the length of the second connecting portion 122 can be shortened by providing the third connecting portion 123, so that when the second connecting portion 122 receives a swinging force from the driving member 13, since the length of the second connecting portion 122 is shortened, the strength of the second connecting portion 122 will be stronger and less prone to deform, and further the strength of the entire anti-shake mechanism 100 can be stronger and less prone to deform.

The first pushing member 11 is a circular ring structure, and an inner annular wall of the circular ring structure encloses to form a first light passing hole 111. Through making first impeller 11 be ring shape structure, because ring shape structure is difficult to produce the condition of stress concentration, consequently, can be so that first impeller 11 is difficult to take place the condition of deformation or fracture, and then can make whole anti-shake mechanism 100's intensity higher.

Of course, the first pushing member 11 may also have other shapes, for example, the first pushing member 11 may also have a rectangular ring structure or a polygonal ring structure, which is not limited in the embodiments of the present application.

In some embodiments, referring to fig. 2, the number of the connecting members 12 is multiple (the number of the connecting members 12 is 4 in fig. 2), 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 pieces 12 plural and making the plural connecting pieces 12 arranged at intervals on the outer edge of the first urging piece 11, the plural connecting pieces 12 can support the first urging piece 11 collectively at plural different positions of the first urging piece 11, so that the first urging piece 11 can be made less likely to be deformed.

Further, in some embodiments, referring to fig. 2, the links 12 are evenly spaced on the outer edge of the first pusher 11. When the connecting pieces 12 are uniformly arranged at the outer edge of the first pushing piece 11 at intervals, the connecting pieces 12 can uniformly support the first pushing piece 11 at all positions of the first pushing piece 11 together, so that the stress at all positions of the first pushing piece 11 is uniform, the first pushing piece 11 is less prone to deformation, and enough thrust can be provided by the connecting pieces 12 to drive the first pushing piece 11 to move.

The number of the connecting members 12 may be 2, or 3, 4, or 5, which is not limited in the embodiment of the present application.

In some embodiments, referring to fig. 2 and 3, the first connecting portion 121 has a circular arc structure (i.e., a cross section of the first connecting portion 121 parallel to the cross section of the first pushing member 11 in fig. 3 has a circular arc shape, i.e., a cross section of the first connecting portion 121 in the plane of the dotted line S in fig. 3 has a circular arc shape), and an axis of the circular arc structure is parallel to the axis Z1 of the first light passing hole 111. Through making first connecting portion 121 be circular arc structure to make the axis of circular arc structure and the axis Z1 of first light hole 111 be parallel, can make first connecting portion 121 bear the ability of being parallel to the axis Z1 direction's of first light hole 111 power stronger, and then can make first connecting portion 121 be difficult to take place to warp, thereby can make whole anti-shake mechanism 100's intensity higher.

To make the overall anti-shake mechanism 100 stronger, further, in some embodiments, referring to fig. 2, the anti-shake mechanism further includes a second pushing member 14, and each of the plurality of second connecting portions 122 is connected to the driving member 13 through the second pushing member 14. By connecting the second connecting portions 122 to the second pushing member 14 and connecting the second pushing member 14 to the driving member 13, the second pushing member 14 can play a role of fixing the second connecting portions 122 on itself, so that the positional relationship among the second connecting portions 122 can be restrained by the second pushing member 14, and further the second connecting portions 122 form a whole, that is, the connecting members 12 form a whole, so that the strength of the whole formed by the connecting members 12 is stronger, and further the strength of the whole anti-shake mechanism 100 is higher.

In some embodiments, referring to fig. 2, the second pushing member 14 is a metal member, and the part of the driving member 13 for fixing with the second pushing member 14 is a plastic member, and a welding metal is embedded in the plastic member at a position corresponding to the second pushing member 14, and the welding metal and the second pushing member 14 are fixed by laser welding.

When the second pushing member 14 is a metal member and the driving member 13 is used for fixing 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 and fixing by embedding welding metal in a position corresponding to the second pushing member 14 in the plastic member, so that the driving member 13 can be very stably fixed to the second pushing member 14, and the driving member 13 can be prevented from falling off from the second pushing member 14.

In addition, when second pushing member 14 is a metal member, second pushing member 14 can have higher strength, and thus, the strength of entire anti-shake mechanism 100 can be higher. When the driving member 13 is a plastic member for fixing with the second pushing member 14, the weight of the driving member 13 can be reduced to some extent, and the whole anti-shake mechanism 100 can be made lighter.

The welding metal may be a metal such as iron or aluminum, and the welding metal is not limited in the embodiments of the present application. In addition, the metal member may be specifically an iron member, a stainless steel member, or the like, which is not limited in the embodiment of the present application.

In some embodiments, referring to fig. 2, the second pushing member 14 is a circular ring structure, and two opposite sides of the second pushing member 14 are connected to the second connecting portion 122 and the driving member 13, respectively. When the second pushing member 14 is a circular ring structure, the circular ring structure can avoid the occurrence of a situation of stress concentration to a certain extent, so that the occurrence of a situation of local deformation or fracture of the second pushing member 14 can be avoided, the strength of the second pushing member 14 is higher, and the strength of the whole anti-shake mechanism 100 is higher.

To further increase the strength of the overall anti-shake mechanism 100, further, in some embodiments, the loop width of first urging member 11 is greater than the loop width of second urging member 14.

By making the axis of the second light passing hole 140 coincide with the axis Z1 of the first light passing hole 111, on one hand, the second light passing hole 140 can be prevented from being dislocated relative to the first light passing hole 111, which is more beneficial for light to smoothly pass through the second light passing hole 140 after passing through the first light passing hole 111. On the other hand, the structure of the whole anti-shake mechanism 100 is regular and beautiful, and the situation that the stress on each position of the second pushing member 14 or each position of the first pushing member 11 is not uniform can be avoided to a certain extent, so that the situation that the local position of the second pushing member 14 or the local position of the first pushing member 11 is deformed can be avoided, and further the strength of the anti-shake mechanism 100 is higher.

That is to say, the installation portions 141, the connecting members 12 and the driving members 13 are arranged in a one-to-one correspondence manner, and since the driving members 13 are used for driving the corresponding installation portions 141 to move in a direction parallel to the axis Z1 of the first light passing hole 111, the connecting members 12 and the driving members 13 are arranged in a one-to-one correspondence manner, the connecting members 12 can better bear the force from the driving members 13, and thus the occurrence of the deformation of the anti-shake mechanism 100 can be avoided.

Because the pre-positioning mode through the first positioning hole 151 and the positioning post 152 has a simple structure and a mature technology, the design cost and the manufacturing cost of the pre-positioning structure 15 can be reduced to a certain extent.

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

Based on the above description, the anti-shake movable portion 131 can move along the direction parallel to the axis Z1 of the first light passing hole 111, and therefore, when the anti-shake movable portion 131 moves along the direction parallel to the axis Z1 of the first light passing hole 111, the elastic sheet 135 can be deformed and move along with the anti-shake movable portion 131, and based on this, the avoiding groove 1312 is disposed at the position of the anti-shake movable portion 131 corresponding to the elastic sheet 135, so as to provide a deformation space for the elastic sheet 135, so that, on one hand, collision between the elastic sheet 135 and the anti-shake movable portion 131 can be avoided, which results in the anti-shake movable portion 131 being scratched by the elastic sheet 135, and on the other hand, occurrence of collision noise between the elastic sheet 135 and the anti-shake movable portion 131 can be avoided.

That is, only the elastic sheet 135 and the anti-shake movable portion 131 need to be pre-positioned, and the third positioning portion 1313 and the fourth positioning portion 1351 are not limited in this embodiment.

By arranging the anti-collision chamfer 1314, the anti-shake movable part 131 can be prevented from colliding with other parts to a certain extent or the anti-shake movable part 131 itself is prevented from colliding with other parts, so that the whole anti-shake mechanism 100 is more firm and durable.

In summary, in the embodiment of the present invention, during anti-shake, since the driving element 13 is connected to the first connecting portion 121, when the driving element 13 moves, the first connecting portion 121 can be driven to move, and when the first connecting portion 121 moves, since the first connecting portion 121 is connected to the first pushing element 11, the first pushing element 11 can move. At this time, since the first pushing member 11 includes the first light passing hole 111, and the liquid lens 200 is disposed at the first light passing hole 111, when the first pushing member 11 moves, the liquid lens 200 can be driven to swing, so as to change the inclination angle a of the liquid lens 200. Therefore, when the anti-shake mechanism 100 is applied to a camera module, after the inclination angle a of the liquid lens 200 is changed, the angle, the position, and the like of the light entering the camera module through the first light passing hole 111 and the liquid lens 200 can be changed, so that the camera module can realize an anti-shake function.

When the purpose of driving the liquid lens to swing is achieved, the liquid lens is disposed at the first light passing hole 111 of the first pushing element 11, so that the purpose of driving the liquid lens to swing can be achieved by swinging the first pushing element 11, and the swinging of the first pushing element 11 is achieved by driving the first connecting portion 121 by the driving element 13, so that the driving force of the driving element 13 can be transmitted to the first pushing element 11 through the first connecting portion 121, in other words, the driving force of the driving element 13 cannot be directly applied to the first pushing element 11, the first connecting portion 121 can play a role of transmitting the driving force, and further can play a role of uniformly transmitting the driving force of the driving element 13 to the first pushing element 11, when the driving force of the driving element 13 can be uniformly transmitted to the first pushing element 11, the swinging of the first pushing element 11 can be more uniform, and further the swinging of the liquid lens can be more uniform, 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.

In addition, as can be seen from the above description, since the anti-shake function is realized by the anti-shake mechanism 100 driving the liquid lens 200 to swing, it can be understood that the weight of the liquid lens 200 is light, and the force required by the anti-shake mechanism 100 to swing the liquid lens 200 is small, therefore, the anti-shake mechanism 100 in the embodiment of the present application does not need to be as firm and heavy 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, and further, the whole camera module can be small and light.

In addition, since the first connecting portion 121 extends along the axis Z1 direction (i.e., Z direction in fig. 4) of the first light passing hole 111, 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 passing hole 111 to form the second connecting portion 122, the first pushing member 11, the first connecting portion 121, and the second connecting portion 122 may collectively form a "step" structure. When the first pushing element 11, the first connecting portion 121 and the second connecting portion 122 form a "ladder" structure, a vacant space K can be formed between the first connecting portion 121 and the second connecting portion 122, so that the occupied volume of the connecting element 12 is small, and the size of the anti-shake mechanism 100 is small, and meanwhile, the vacant space K can be vacant to place other components, so that the whole anti-shake mechanism 100 becomes small.
