Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of structures that are consistent with some aspects of the disclosure as detailed in the appended claims.

At present, as shown in fig. 1a and 1b, the basic structure of a suspension wire and spring piece OIS motor used in a mobile phone is that four magnets 21 are arranged on the OIS motor 20, an Auto Focus (AF) coil 22 is wound on a lens carrier, and when the power is on, the lens can be driven to move in the focusing direction, namely the Z-axis direction under the action of electromagnetic force, so as to realize Auto Focus; the focusing direction is a direction perpendicular to the screen of the mobile phone. The OIS coil 23 is printed on the flexible circuit board and is bound with the motor base, and when the motor is powered on, the whole lens carrier (comprising the AF coil and the magnet part) is pushed under the action of electromagnetic force, so that the function of anti-shake in the X, Y axial direction is realized. However, the connection structure of the suspension wire 24 and the elastic piece 25 in the OIS motor 20 is complex, a large amount of hot riveting and welding are included in the process flow, and the elastic coefficient value of the elastic piece 25 in the motor does not reach the standard, so that the lens of the mobile phone is easy to incline, and the problem of reliability exists.

Based on this, the embodiment of the disclosure provides a camera module. Fig. 2 is a schematic structural diagram of a camera module according to an exemplary embodiment, and as shown in fig. 2, the camera module 10 may include:

A base 11;

an anti-shake unit 12, which is disposed on the base 11 and is capable of providing anti-shake processing for the camera module 10;

the focusing assembly 13 is sleeved in the anti-shake assembly 12 and can provide focusing treatment for the camera module 10;

and a sliding component 14 connected between the focusing component 13 and the anti-shake component 12 and capable of enabling the focusing component 13 to move relative to the anti-shake component 12 in a focusing direction Z.

In the embodiment of the disclosure, the camera module may be applied to a focusing and/or anti-shake scene, for example, may be applied to a scene with shooting range adjustment, such as object tracking.

The base may be a carrier for carrying the anti-shake unit, the focusing unit, and the like. The anti-shake component may be a component for implementing an anti-shake function of the camera module; for example, the anti-shake assembly may include a bracket that supports the focusing assembly and OIS magnet. The focusing component can be a component for realizing the focusing function of the camera module; for example, the focusing assembly may include a carrier that supports the lens and an AF magnetic member.

The sliding component may be a component for providing a movable space for movement between the focusing component and the anti-shake component; for example, the above-described sliding assembly may include a sliding rail and a slider, and the slider may slide in the sliding rail; or, the sliding component may further include a sliding groove and a bump clamped with the sliding groove, the bump may slide in the sliding groove, and the bump and the focusing component are integrally formed.

For example, the sliding track in the sliding assembly may be disposed on a side of the anti-shake assembly facing the focusing assembly, and the sliding member in the sliding assembly may be movably disposed on a side of the focusing assembly facing the anti-shake assembly and in the sliding track, so that the sliding member may slide in the sliding track to enable the focusing assembly to move relative to the anti-shake assembly.

Here, the focusing assembly and the anti-shake assembly may be slidably connected through the sliding assembly; the focusing direction may be a direction perpendicular to the base.

It can be appreciated that when the camera module is applied to a focusing scene, the focusing assembly can move in a focusing direction, such as a Z-axis direction, relative to the anti-shake assembly, so that the positions of lenses in the camera module can be different, thereby realizing an auto-focusing function of the camera module.

Similarly, when the camera module is applied to an anti-shake scene, the anti-shake component can move relative to the base in a direction perpendicular to the focusing direction, such as X, Y axial direction, so that the positions of lenses in the camera module can be different, and an anti-shake function of the camera module is realized. For example, the anti-shake assembly and the base may be connected by an elastic connection (e.g., a suspension wire) that provides a space for movement between the anti-shake assembly and the base.

It should be noted that, the structure for implementing the auto-focusing and anti-shake functions in the camera module may include, but is not limited to, an electromagnetic structure or a piezoelectric driving structure, and the embodiments of the present disclosure are not limited to. For example, the interaction force between the coil and the magnet can be utilized to drive the focusing assembly to move relative to the anti-shake assembly, so as to realize an auto-focusing function; or, the anti-shake component can be driven to move relative to the base by using the inverse piezoelectric effect of the piezoelectric driving structure so as to realize the anti-shake function; etc.

In one embodiment of the present disclosure, as shown in fig. 2, the camera module 10 may further include:

a cover shell 19 enclosing an accommodating space with the base 11; the anti-shake component 12 and the focusing component 13 are both positioned in the accommodating space; the cover 19, the focusing assembly 13, the anti-shake assembly 12 and the base 11 all have an aligned through hole 100;

the lens is installed at the through hole 100 and exposed through the through hole 100 to collect external ambient light.

Thus, the lens can be installed through the cover shell, the focusing assembly, the anti-shake assembly and the through holes on the base, so that the position of the lens is fixed, and the focusing and anti-shake functions of the camera module are better realized.

Wherein, the cover shell and the base can form a shell for fixing the lens; the lens (not shown in fig. 2) may be composed of several lenses, and is capable of collecting external ambient light.

It should be noted that, the cover and the base may be connected by various manners to enclose the accommodating space, which is not limited in the embodiments of the disclosure. For example, the cover shell can be connected and fixed with the base through a connection mode such as screw connection, plug connection, buckle connection, welding, bonding and the like.

It can be appreciated that the shape of the through hole can be matched with the shape of the lens, so that the lens can be exposed through the through hole, thereby collecting external ambient light and transmitting the ambient light to the image sensor for imaging. In the embodiment of the disclosure, the lens may partially protrude from the through hole in a direction toward the object photographed by the camera module; alternatively, the lens may be entirely located in the accommodating space.

It should be noted that, the specific shape of the casing enclosed by the cover casing and the base may be set according to practical application, and the embodiment of the disclosure is not limited. For example, the housing may be a rectangular parallelepiped having the above-mentioned through holes, or the housing may be a square having the above-mentioned through holes, or the like.

The embodiment of the disclosure provides a camera module, the camera module includes: a base; the anti-shake assembly is positioned on the base and can provide anti-shake treatment for the camera module; the focusing assembly is sleeved in the anti-shake assembly and can provide focusing treatment for the camera module; and the sliding component is connected between the focusing component and the anti-shake component and can enable the focusing component to move relative to the anti-shake component in the focusing direction. In this way, in the camera module of the embodiment of the disclosure, the design of the spring piece assembly is canceled, and the sliding assembly is arranged in the focusing direction between the focusing assembly and the anti-shake assembly, so that the focusing assembly moves in the focusing direction relative to the anti-shake assembly, and therefore the lens in the camera module is not easy to incline, and the reliability of the camera module is improved; meanwhile, the camera module is simple in structure and process, the production efficiency of the camera module can be effectively improved, and the production cost is reduced.

Fig. 3 is a schematic diagram of a camera module according to an exemplary embodiment. As shown in fig. 3, the sliding assembly 14 in the camera module provided in the embodiment of the present disclosure may include:

A sliding rail 141 located on a surface of the anti-shake assembly 12 facing the focusing assembly 13 and disposed along the focusing direction Z;

a sliding member 142 movably disposed at an outer edge of the focusing assembly 13 and at least partially positioned in the sliding track 141;

the focusing assembly 13 is movable relative to the anti-shake assembly 12 when the slider 142 slides in the slide rail 141.

Here, the slide rail may be a member for sliding the slider; the slide may include, but is not limited to, a sliding ball.

It is understood that when the focusing assembly is sleeved in the anti-shake assembly, the sliding parts can be all located in the sliding track; after the focusing assembly moves relative to the anti-shake assembly, the sliding member may be partially located in the sliding track.

In one embodiment of the present disclosure, as shown in fig. 3, two adjacent side edges of the anti-shake assembly 12 are connected to form an anti-shake angle 121; the sliding rail 141 is disposed at the anti-shake angle 121. Therefore, the sliding rail can be arranged at the anti-shake included angle, so that sliding connection between the anti-shake component and the focusing component can be realized more conveniently.

Wherein, the anti-shake included angle may be any included angle formed by two adjacent sides of the anti-shake assembly.

It should be noted that, the angle of the anti-shake angle may be set according to practical application conditions, and the embodiments of the disclosure are not limited. For example, the angle of the anti-shake angle may be smaller than 90 degrees; alternatively, the angle of the anti-shake angle may be equal to 90 degrees; or, the angle of the anti-shake included angle may be greater than 90 degrees and less than 180 degrees; etc.

In addition, the number of the anti-shake included angles can be determined according to the specific shape of the anti-shake assembly in the practical application situation; the number of the sliding tracks may be set according to the number of the anti-shake angles, which is not limited in the embodiments of the disclosure. For example, the number of the sliding rails may be one or more, so long as the number of the sliding rails is less than or equal to the number of the anti-shake angles; for example, the number of the sliding rails may be the same as the number of the anti-shake angles.

In some embodiments, as shown in fig. 3, the sliding rail 141 is a plurality of sliding rails; a plurality of the sliding rails 141 are disposed at different anti-shake angles 121 of the anti-shake assembly 12. Thus, the sliding connection between the anti-shake component and the focusing component can be further and more stably realized by arranging the plurality of sliding rails at different anti-shake included angles.

Here, each of the plurality of the sliding rails may be disposed at a different one of the anti-shake angles. That is, when the number of the sliding tracks is equal to the number of the anti-shake angles, one sliding track is correspondingly arranged at one anti-shake angle; when the number of the sliding tracks is smaller than the number of the anti-shake included angles, at least one anti-shake included angle is not arranged at the position where the sliding tracks are arranged.

For example, when the anti-shake assembly is a hollow cuboid, the number of the anti-shake angles may be four; correspondingly, the number of the sliding rails can be four, so that the anti-shake assembly and the focusing assembly can be more stably connected in a sliding manner.

In one embodiment of the present disclosure, as shown in fig. 3, one of the sliding rails 141 corresponds to at least one of the sliding members 142, and a plurality of the sliding members 142 corresponding to one of the sliding rails 141 are arranged along the focusing direction Z. Therefore, at least one sliding piece and one sliding track can be matched with each other, so that the lens in the camera module is not easy to incline when the focusing assembly moves relative to the anti-shake assembly, and the reliability of the camera module is improved.

It is understood that a plurality of the sliding members may be movably disposed at an outer edge of the focusing assembly along the focusing direction, so that at least a portion of the sliding members may be located in the sliding tracks correspondingly disposed.

It should be noted that, the specific number of the sliding pieces corresponding to the sliding track may be set according to actual application, and the embodiment of the disclosure is not limited. For example, one of the sliding rails corresponds to one of the sliding members; alternatively, one of the slide rails corresponds to two of the slides; or, one of the sliding rails corresponds to three sliding members; etc.

According to the camera module provided by the embodiment of the disclosure, the sliding rail is arranged at the anti-shake included angle formed by connecting the two adjacent side edges of the anti-shake assembly, and the sliding rail and the sliding piece are arranged along the focusing direction, so that the focusing assembly can move in the focusing direction relative to the anti-shake assembly more stably; meanwhile, at least one sliding piece is matched with one sliding track, so that the lens in the camera module is not easy to incline when the focusing assembly moves relative to the anti-shake assembly, and the reliability of the camera module is improved.

Fig. 4 is a schematic diagram of a camera module according to an exemplary embodiment. As shown in fig. 4, the camera module 10 provided in the embodiment of the present disclosure may further include:

a flexible circuit board 15;

a plurality of coils 16 of different functions located on different surfaces of the flexible circuit board 15;

a hall sensor 17 located in an area surrounded by the plurality of coils 16;

a control driving member 18 connected to the hall sensor 17 and configured to control the on/off of the plurality of coils 16 based on the position of the anti-shake assembly 12 and the position of the focusing assembly 13 detected by the hall sensor 17.

In the embodiment of the disclosure, the flexible circuit board (Flexible Printed Circuit, FPC) may be a flexible printed circuit board made of polyimide or polyester film as a base material, which has high reliability, and the FPC has the characteristics of high wiring density, light weight, thin thickness and good flexibility.

The coils can be coils in electromagnetic structures for realizing different functions of the camera module; for example, the coils may include, but are not limited to, a focusing coil, a first anti-shake coil, and a second anti-shake coil; the coil can generate a magnetic field when current flows when the coil is electrified. Embodiments of the present disclosure may utilize lorentz forces between an energized coil and a magnetic member, such as a magnet, to drive movement of a focusing assembly or an anti-shake assembly.

The hall sensor may be a magnetic field sensor manufactured according to hall effect, and may be used to detect the position of the anti-shake assembly and the position of the focusing assembly.

Here, the control driver may be a member for controlling the coil to be turned on and off. The control driving member may be disposed on the flexible circuit board and connected to the coil; for example, the control driver may be located on the same side of the flexible circuit board as the hall sensor, or the control driver may be located on a different side of the flexible circuit board from the hall sensor.

The number of the hall sensors may be the same as the number of the coils, and the number of the control driving members may be the same as the number of the hall sensors; alternatively, the number of the hall sensors may be equal to the number of the coils, and the control driver may be one, and one control driver may connect a plurality of the coils and the hall sensors.

It can be understood that, after the control driving piece controls the coil to be electrified at the current moment, lorentz force is generated between the coil and the magnetic piece in the focusing assembly or the anti-shake assembly so as to drive the focusing assembly or the anti-shake assembly to move; at this time, the hall sensor may feed back the detected position change of the anti-shake assembly or the detected position change of the focusing assembly to the control driving member, and the control driving member may control the coil to be in an energized state or a de-energized state at a next time, so as to implement closed-loop control of the focusing assembly or the anti-shake assembly, so as to improve the response speed and the stroke accuracy of focusing or anti-shake processing performed by the camera module.

In the embodiment of the disclosure, the control driving piece may control the plurality of coils to be in an energized state or a de-energized state at the same time; alternatively, the control driving member may control one of the plurality of coils to be in an energized state and another coil to be in a de-energized state; etc.

In some embodiments, as shown in fig. 4, a plurality of the coils 16 includes a focusing coil 161; the focusing assembly 13 includes:

a carrier 131 sleeved in the anti-shake assembly 12;

a focusing magnetic member 132 disposed on a side of the carrier 131 and corresponding to the focusing coil 161;

wherein, when the focusing coil 161 is energized, a first acting force F1 is generated between the focusing coil 161 and the focusing magnetic member 132 to drive the focusing assembly 13 to move relative to the anti-shake assembly 12; the direction of the first acting force F1 is the same as the focusing direction Z.

Therefore, the focusing magnetic piece and the focusing coil are correspondingly arranged, so that the focusing assembly is driven to move relative to the anti-shake assembly by utilizing the first acting force generated between the electrified focusing coil and the focusing magnetic piece, and the automatic focusing function of the camera module is realized.

Here, the focusing coil may be a coil for realizing a focusing function of the camera module; for example, the focusing coil may be an AF coil. The carrier may be a structure for carrying the lens of the camera module. The focusing magnetic member may be a permanent magnet, for example, a focusing magnet (i.e., AF magnet) or an artificial magnet; wherein the permanent magnet may be a magnet capable of maintaining its magnetism for a long period of time. The direction of the first force may be coincident with the focusing direction, for example, the direction of the first force may be a Z-axis direction.

It should be noted that, the specific dimensions of the carrier and the focusing magnetic member may be set according to practical application, and the embodiments of the present disclosure are not limited.

It can be understood that when the camera module needs to perform focusing, the control driving piece can control the focusing coil to be in an energized state, so that a first acting force is generated between the focusing coil and the focusing magnetic piece, and the focusing assembly is driven to move relative to the anti-shake assembly, so that focusing of the lens of the camera module in the direction of the first acting force is achieved.

In some embodiments, as shown in fig. 4, the plurality of coils 16 further includes a first anti-shake coil 162 disposed opposite the focusing coil 161; the anti-shake assembly 12 includes:

The first bracket 122 is located on the base 11 and sleeved outside the carrier 131;

the first anti-shake magnetic element 123 is located on the first bracket 122 and is disposed corresponding to the first anti-shake coil 162;

wherein, when the first anti-shake coil 162 is energized, a second force F2 is generated between the first anti-shake coil 162 and the first anti-shake magnetic element 123 to drive the first bracket 122 to move relative to the base 11; the direction of the second acting force F2 is perpendicular to the direction of the first acting force F1.

Therefore, the first support can be driven to move relative to the base by correspondingly arranging the first anti-shake magnetic piece and the first anti-shake coil so as to utilize second acting force generated between the electrified first anti-shake coil and the first anti-shake magnetic piece, and thus the anti-shake function of the camera module in the second acting force direction is realized.

In an embodiment of the disclosure, the first anti-shake coil may be a coil for implementing an anti-shake function of a camera module; for example, the first anti-shake coil may be an OIS coil. The first support may be a structure for supporting the focusing assembly. The first anti-shake magnetic element may also be a permanent magnet, for example, a first anti-shake magnet (i.e., OIS magnet). The direction of the second force may be perpendicular to the focusing direction, for example, the direction of the second force may be an X-axis direction.

It should be noted that, specific dimensions of the first bracket and the first anti-shake magnetic element may be set according to practical application, and the embodiments of the present disclosure are not limited. For example, the size of the first anti-shake magnetic element may be the same as the size of the focusing magnetic element; alternatively, the first anti-shake magnetic member may have a size different from that of the focusing magnetic member; etc.

It can be understood that when the camera module needs to perform anti-shake processing, the driving part can be controlled to control the first anti-shake coil to be in an electrified state, so that a second acting force is generated between the first anti-shake coil and the first anti-shake magnetic part, and the first bracket is driven to move relative to the base, so that the anti-shake processing of the lens of the camera module in the direction of the second acting force is realized.

In some embodiments, as shown in fig. 4, the plurality of coils 16 further includes a second anti-shake coil 163 located between the focusing coil 161 and the first anti-shake coil 162; the anti-shake assembly 12 further includes:

a second anti-shake magnetic element 124 disposed on the first bracket 122 and corresponding to the second anti-shake coil 163;

wherein, when the second anti-shake coil 163 is energized, a third force F3 is generated between the second anti-shake coil 163 and the second anti-shake magnetic element 124 to drive the first bracket 122 to move relative to the base 11; the direction of the third acting force F3 is perpendicular to the direction of the first acting force F1, and the direction of the third acting force F3 is perpendicular to the direction of the second acting force F2.

Therefore, the second anti-shake magnetic piece and the second anti-shake coil are correspondingly arranged, so that the first support is driven to move relative to the base by utilizing third acting force generated between the electrified second anti-shake coil and the second anti-shake magnetic piece, and the anti-shake function of the camera module in the third acting force direction is realized.

In an embodiment of the disclosure, the second anti-shake coil may also be a coil for implementing an anti-shake function of the camera module; for example, the second anti-shake coil may be an OIS coil. The second anti-shake magnetic element may also be a permanent magnet, for example, a second anti-shake magnet (i.e., OIS magnet). The direction of the third force may be perpendicular to the focusing direction or perpendicular to the second force direction; for example, the direction of the third force may be the Y-axis direction.

It should be noted that, the specific dimensions of the second anti-shake magnetic element may be set according to practical application conditions, so long as the dimensions of the first anti-shake magnetic element and the second anti-shake magnetic element are the same, and the embodiments of the present disclosure are not limited. For example, the second anti-shake magnetic element may have the same size as the focusing magnetic element; alternatively, the second anti-shake magnetic member may have a size different from that of the focusing magnetic member; etc.

It can be understood that when the camera module needs to perform anti-shake processing, the second anti-shake coil can be controlled to be in an energized state by the control driving member, so that a third acting force is generated between the second anti-shake coil and the second anti-shake magnetic member, and the first bracket is driven to move relative to the base, so that anti-shake processing of the lens of the camera module in the direction of the third acting force is realized.

In one embodiment of the present disclosure, as shown in fig. 4, the anti-shake assembly 12 may further include:

an elastic connection member 125 connected between the base 11 and the first bracket 122;
