It should be understood that the specific features in the embodiments of the present specification and the embodiments are detailed descriptions of the technical solutions of the present specification, and are not limitations of the technical solutions of the present specification. In the case of no conflict, the technical features in the embodiments of the present specification and the embodiments can be combined with each other.

Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

The term "two or more" includes two or more than two.

[0050] The motor 10, the camera module 100 and the electronic device 1000 according to some embodiments of the present application will be described below in conjunction with the accompanying drawings. Figures 1-12 The motor 10, the camera module 100 and the electronic device 1000 according to some embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0051] It can be understood that the electronic device 1000 provided by the embodiments of the present application can include but is not limited to a mobile phone, a tablet, a desktop computer, a notebook computer and the like, and the electronic device 1000 has a camera module 100, so that the electronic device 1000 at least has a camera function, wherein the camera module 100 can include a long-focus camera module, an upright camera module, etc., which is not limited here.

[0052] The camera module 100 includes a motor 10 and a lens 20, the lens 20 is installed on the motor 10, and the motor 10 at least includes an anti-shake assembly, the anti-shake assembly is used to drive the lens 20 to move in a direction perpendicular to an optical axis of the lens 20, so that the camera module 100 has an optical anti-shake function.

[0053] As shown in Figure 1 The motor 10 includes a housing 6, the anti-shake assembly can be installed in the housing 6, and the motor 10 is provided with a circuit board 60, the circuit board 60 is used to be electrically connected with an external power supply to realize power supply for the motor 10.

[0054] As shown in Figure 2As shown, the motor 10 comprises a base 1 and an anti-shake carrier 2, the anti-shake carrier 2 is adapted to mount a lens 20, the anti-shake carrier 2 is movably mounted on the base 1 in a direction perpendicular to an optical axis of the lens 20, so that the lens 20 can be driven by the anti-shake carrier 2 in the direction perpendicular to the optical axis of the lens 20 to realize the anti-shake function of the camera module 100.

[0055] Further, as shown, Figure 3 the motor 10 comprises an anti-shake magnet 41, an anti-shake coil 42 and a spacer 3, the anti-shake magnet 41 is arranged on the anti-shake carrier 2, the anti-shake coil 42 is arranged on the base 1, and at least part of the spacer 3 is arranged between the anti-shake magnet 41 and the anti-shake coil 42. It can be understood that the anti-shake coil 42 will drive the anti-shake magnet 41 to move after being energized, the anti-shake magnet 41 drives the lens 20 to move through the anti-shake carrier 2, thereby realizing the anti-shake function of the camera module 100.

[0056] In some implementations, the driving force of the anti-shake coil 42 is positively related to the number of turns of the anti-shake coil 42, that is, the more the number of turns of the anti-shake coil 42, the greater the driving force of the anti-shake coil 42. Therefore, the present application can increase the driving force of the anti-shake coil 42 by increasing the number of turns of the anti-shake coil 42, thereby facilitating the increase of the anti-shake stroke.

[0057] It should be noted that in the related art, the anti-shake coil 42 and the anti-shake magnet 41 are distributed in a direction perpendicular to the optical axis of the lens 20, which will cause the size of the motor 10 in the direction perpendicular to the optical axis to be larger, which is not conducive to the miniaturization design of the motor 10 in the direction perpendicular to the optical axis.

[0058] Therefore, in the present application, the anti-shake magnet 41, the spacer 3 and the anti-shake coil 42 are arranged in the direction of the optical axis of the lens 20, so that the distribution of the anti-shake magnet 41 and the anti-shake coil 42 will not occupy space in the direction perpendicular to the optical axis, thereby facilitating the reduction of the size of the motor 10 in the direction perpendicular to the optical axis.

[0059] At the same time, since the anti-shake coil 42 drives the anti-shake magnet 41 to move when energized, the anti-shake carrier 2 is driven by the anti-shake magnet 41 to move in the direction perpendicular to the optical axis, and the distribution direction of the anti-shake magnet 41 and the spacer 3 is the direction of the optical axis, so that the distribution direction of the anti-shake magnet 41 and the spacer 3 is perpendicular to the movement of the anti-shake magnet 41, thereby reducing the interference risk of the anti-shake magnet 41 and the spacer 3, and further improving the stability of the anti-shake function of the camera module 100.

[0060] In some embodiments, as shown, Figure 4 the spacer 3 is provided with a first receiving space 311, and part or all of the anti-shake magnet 41 is received in the first receiving space 311.

[0061] For example, the first receiving space 311 is open toward the anti-shake magnet 41. This facilitates partial or complete storage of the anti-shake magnet 41 within the first receiving space 311, thereby making the spacer 3 and the anti-shake magnet 41 more compact. Furthermore, the provision of the first receiving space 311 helps reduce the thickness of the spacer 3 along the optical axis, thereby reducing the impact of the spacer 3 on the overall size of the motor 10 along the optical axis.

[0062] and / or Figure 4 As shown, the spacer 3 defines a second receiving space 312 , and part or all of the anti-shake coil 42 is received in the second receiving space 312 .

[0063] For example, the second receiving space 312 is open toward the base 1 , allowing for partial or full storage of the anti-shake coil 42 within the second receiving space 312, thereby making the spacer 3 and anti-shake coil 42 more compact. Furthermore, the provision of the second receiving space 312 helps reduce the thickness of the spacer 3 along the optical axis, thereby minimizing the impact of the spacer 3 on the overall dimensions of the motor 10 along the optical axis. In other words, by providing the first receiving space 311 and the second receiving space 312, the length and width of the motor 10 can be reduced without substantially increasing its thickness.

[0064] In some implementations, such as Figure 5 and Figure 9 As shown, the anti-shake magnet 41 includes a first magnet 411 and a second magnet 412, and the anti-shake coil 42 includes a first coil 421 and a second coil 422. It will be understood that the first magnet 411 and the first coil 421 are disposed opposite each other and are used to drive the anti-shake carrier 2 to move in a first direction X, while the second magnet 412 and the second coil 422 are disposed opposite each other and are used to drive the anti-shake carrier 2 to move in a second direction Y. The first direction X and the second direction Y are both perpendicular to the optical axis and are perpendicular to each other.

[0065] In this way, the anti-shake carrier 2 can be driven to achieve anti-shake movement in different directions through different combinations of magnets and coils (a combination of the first magnet 411 and the first coil 421 or a combination of the second magnet 412 and the second coil 422), thereby improving the anti-shake function of the camera module 100.

[0066] In some implementations, a spacer 3 is provided between the first magnet 411 and the first coil 421 and between the second magnet 412 and the second coil 422 .

[0067] It can be understood that in some arrangements, the first magnet 411 and the second magnet 412 are arranged on different sides of the anti-shake carrier 2, and the arrangement directions of the first magnet 411 and the second magnet 412 are substantially perpendicular and arranged along the circumference of the anti-shake carrier 2, and the first magnet 411 and the first coil 421 and the second magnet 412 and the second coil 422 are both provided with a spacer 3, so that the spacer 3 can also be arranged around at least part of the anti-shake carrier 2 along the arrangement direction of the first magnet 411 and the second magnet 412, so that the spacer 3 can be arranged in cooperation with the arrangement direction of the first magnet 411 and the second magnet 412.

[0068] In some embodiments, as shown in Figure 4 The spacer 3 includes a spacing portion 31 and a cooperation portion 32, as shown in Figure 3 The spacing portion 31 is arranged between the anti-shake magnet 41 and the anti-shake coil 42, and the cooperation portion 32 is located between the anti-shake carrier 2 and the base 1 and is connected with the spacing portion 31, and the cooperation portion 32 is provided with a first cooperation groove 321 extending along the first direction X and a second cooperation groove 322 extending along the second direction Y, the first cooperation groove 321 is towards the anti-shake carrier 2, and the second cooperation groove 322 is towards the base 1; wherein the first cooperation groove 321 is provided with a first ball 212 abutting against the anti-shake carrier 2, and the second cooperation groove 322 is provided with a second ball 12 abutting against the base 1, and the first direction X intersects with the second direction Y.

[0069] It can be understood that the anti-shake carrier 2 is used to drive the lens 20 to move relative to the base 1 in a plane perpendicular to the optical axis of the lens 20, and when the anti-shake carrier 2 drives the lens 20 to move relative to the base 1 in the first direction X, since the first cooperation groove 321 is provided with the first ball 212 abutting against the anti-shake carrier 2, at this time, the anti-shake carrier 2 moves relative to the base 1 and the cooperation portion 32 in the first direction X, and the first ball 212 rolls in the first sliding groove 211 along the first direction X, so that the anti-shake function of the camera module 100 in the first direction X can be realized.

[0070] At the same time, since the first ball 212 rolls in the first sliding groove 211, compared with the sliding cooperation between the anti-shake carrier 2 and the base 1, the sliding friction of the anti-shake carrier 2 relative to the base 1 can be converted to rolling friction, so as to facilitate reducing the friction of the anti-shake carrier 2 relative to the base 1 in the first direction X, and is beneficial to reducing the wear of the anti-shake carrier 2 and / or the base 1, especially, it is convenient to reduce the driving force required for the anti-shake carrier 2 to move in the first direction X, thereby facilitating to reduce the load.

[0071] When the lens 20 is moved by the anti-shake carrier 2 relative to the base 1 in the second direction Y, since the second sliding groove 11 is provided with the second ball 12 abutting against the base 1, at this time, the anti-shake carrier 2 and the matching part 32 are moved relative to the base 1 in the second direction Y, and the second ball 12 rolls in the second sliding groove 11 in the second direction Y, so that the anti-shake function of the camera module 100 in the second direction Y can be realized.

[0072] Meanwhile, since the second ball 12 rolls in the second sliding groove 11, compared with the sliding fit between the anti-shake carrier 2 and the base 1, the sliding friction of the anti-shake carrier 2 relative to the base 1 can be converted into rolling friction, so that it is convenient to reduce the friction of the anti-shake carrier 2 relative to the base 1 in the second direction Y, and it is beneficial to reduce the wear of the anti-shake carrier 2 and / or the base 1, and in particular, it is convenient to reduce the driving force required for the anti-shake carrier 2 to move in the second direction Y, thereby facilitating the reduction of the load.

[0073] In this way, the anti-shake carrier 2 can realize the anti-shake function in a single direction through the cooperation of a ball and a sliding groove, and the first direction X and the second direction Y intersect, which can reduce the problem of cross talk of the anti-shake carrier 2 in different directions. Thus, the extension length of the first sliding groove 211 and / or the second sliding groove 11 can be increased, thereby expanding the anti-shake stroke of the anti-shake carrier 2 in the corresponding direction, and further increasing the anti-shake angle. At the same time, since the first direction X and the second direction Y intersect, when the anti-shake stroke is increased, the problem of cross talk in different directions caused by the increase of the anti-shake stroke of the anti-shake carrier 2 can be reduced, thereby facilitating the increase of the anti-shake angle of the camera module 100 to meet the use requirements of users.

[0074] In some implementations, the first direction X is perpendicular to the second direction Y, so that the problem of cross talk of the anti-shake carrier 2 in different directions can be further reduced, thereby facilitating the expansion of the anti-shake stroke of the anti-shake carrier 2, and further increasing the anti-shake angle.

[0075] In some implementations, the first ball 212 can be a single ball or a ball group composed of a plurality of balls arranged in the first direction X in sequence, and / or the second ball 12 can be a single ball or a ball group composed of a plurality of balls arranged in the second direction Y in sequence, which is not limited herein.

[0076] In some embodiments, as shown in Figure 6 , the anti-shake carrier 2 is provided with the first sliding groove 211, as shown in Figure 3 , the first sliding groove 211 is oppositely arranged with the first matching groove 321, and the inner wall of the first sliding groove 211 abuts against the first ball 212. In this way, the rolling direction of the first ball 212 can be limited by the first sliding groove 211, so that the first ball 212 can stably roll in the first matching groove 321.

[0077] In some embodiments, as shown in Figure 7 The base 1 is provided with a second sliding groove 11, as shown in Figure 3 The second sliding groove 11 is arranged opposite to the second matching groove 322, and the inner wall of the second sliding groove 11 abuts against the second ball 12. In this way, the rolling direction of the second ball 12 can be limited through the second sliding groove 11, so as to ensure that the second ball 12 can stably roll in the second matching groove 322.

[0078] In some embodiments, as shown in Figure 4 The first matching groove 321 and the second matching groove 322 are respectively arranged on the opposite sides of the matching part 32.

[0079] In this way, the arrangement of the first matching groove 321 and the second matching groove 322 can match the distribution direction of the anti-shake carrier 2 and the base 1, so as to facilitate the arrangement of the first matching groove 321 opposite to the first sliding groove 211 and the second matching groove 322 opposite to the second sliding groove 11.

[0080] In some embodiments, the matching part 32 is provided with a plurality of matching parts 32 arranged around the anti-shake carrier 2.

[0081] It can be understood that the first sliding groove 211 can be provided with a plurality of first sliding grooves 211 arranged around the anti-shake carrier 2, the second sliding groove 11 can be provided with a plurality of second sliding grooves 11 arranged around the anti-shake carrier 2, and the matching part 32 can also be provided with a plurality of matching parts 32 arranged around the anti-shake carrier 2, so that each first matching groove 321 is opposite to one first sliding groove 211, and each second matching groove 322 is opposite to one second sliding groove 11. In this way, the stability of the anti-shake carrier 2 moving in the first direction X and the second direction Y can be improved.

[0082] In some embodiments, as shown in Figure 4 The adjacent two matching parts 32 are connected through the spacing part 31.

[0083] In this way, the plurality of matching parts 32 can be installed synchronously, so as to reduce the difficulty of simultaneous installation of the plurality of matching parts 32.

[0084] In some embodiments, the spacing part 31 can be a metal piece, or a combination of metal and plastic. In this way, the spacing part 31 can be made thinner while having sufficient structural strength, so as to facilitate the miniaturization design of the spacing part 31, and further reduce the thickness size of the motor 10.

[0085] In some embodiments, the matching part 32 can be an injection molded piece, or a combination of metal and plastic. In this way, the matching part 32 can be integrally formed, so as to reduce the difficulty of the arrangement.

[0086] In some embodiments, the spacing part 31 and the matching part 32 are an integral structure or integrally formed, that is, the spacing piece 3 is an integral structure, so that the installation of the spacing part 31 and the matching part 32 is not required separately, so as to reduce the difficulty of setting the spacing piece 3.

[0087] In some embodiments, as shown in Figure 5 The anti-shake carrier 2 includes a first part 21 and a second part 22, the first part 21 includes a first step surface 213, and the second part 22 includes a second step surface 221, and the first step surface 213 and the second step surface 221 are connected to form a step.

[0088] It can be understood that, in order to realize the miniaturization and integrated design of the motor 10, the anti-shake carrier 2 is usually sleeved on the partial lens 20, compared with the technical solution in which the size of the anti-shake carrier 2 in the direction of the optical axis is unchanged, in the present application, the first part 21 can be designed to have the first step surface 213, and the second part 22 can be designed to have the second step surface 221, and the first step surface 213 and the second step surface 221 are connected to form a step, so as to facilitate the miniaturization design of the motor 10.

[0089] For example, along the direction of the optical axis, the anti-shake can be divided into the first part 21 and the second part 22, the first part 21 can be used for installing the anti-shake magnet 41, and the second part 22 can be used for installing the partial lens 20. In some implementations, in order to realize the miniaturization and integrated design of the motor 10, it is usually necessary to set the focusing assembly 5 for realizing the focusing of the lens 20 in the first part 21, and since the second part 22 does not have the setting requirement, the cross-sectional area of the second part 22 can be made smaller and smaller than the cross-sectional area of the first part 21 under the condition that the second part 22 meets the installation requirement of the lens 20, so that the connection part of the first part 21 and the second part 22 forms a step, thereby reducing the volume of the second part 22, and further realizing the miniaturization design of the motor 10.

[0090] In some embodiments, as shown in Figure 5 The motor 10 further includes a focusing assembly 5, the focusing assembly 5 includes a focusing magnet 51, a focusing coil 52, and a flexible circuit board 53 electrically connected with the focusing coil 52, the focusing magnet 51 and the focusing coil 52 are oppositely arranged, one end of the flexible circuit board 53 is electrically connected with the connecting terminal of the base 1, and the flexible circuit board 53 is vertically arranged on the first step surface 213 and surrounds part or all of the second step surface 221. In this embodiment, the flexible circuit board 53 surrounds part of the second step surface 221, and in other embodiments, according to the design requirement, it can also be designed to surround all of the second step surface 221.

[0091] It can be understood that the focusing magnet 51 can be arranged on the lens 20, and the focusing coil 52 can be arranged on the anti-shake carrier 2. The focusing coil 52 is used to drive the focusing magnet 51 to move in the direction of the optical axis when powered, so as to realize the focusing function of the lens 20, and the flexible circuit board 53 is used to supply power to the focusing coil 52.

[0092] Further, as shown in Figure 5 , the first step surface 213 can be a horizontal surface substantially perpendicular to the optical axis, and the second step surface 221 is a vertical surface substantially parallel to the optical axis. The flexible circuit board 53 is arranged on the first step surface 213 and surrounds part or all of the second step surface 221, so that the flexible circuit board 53 can make full use of the structure at the step to be arranged. In particular, the flexible circuit board 53 is arranged on the first step surface 213 and can reduce the influence of the size in the direction perpendicular to the optical axis, thereby facilitating the miniaturization design of the motor 10.

[0093] In some embodiments, as shown in Figure 8 , the focusing assembly 5 further comprises a magnetic member, as shown in Figure 5 , one end of the flexible circuit board 53 is electrically connected with the connecting terminal of the base 1, and the other end of the flexible circuit board 53 can be connected with the magnetic member. The magnetic member is arranged on the side of the focusing coil 52 away from the focusing magnet 51, and the magnetic member is magnetically attracted to the focusing magnet 51.

[0094] It can be understood that when the lens 20 is installed on the anti-shake carrier 2, in order to ensure the realization of the focusing movement of the lens 20, the focusing magnet 51 arranged on the lens 20 needs to be accurately matched with the focusing coil 52. In the present application, the magnetic member 54 magnetically attracted to the focusing magnet 51 is arranged on the flexible circuit board 53, so that in the installation process of the lens 20, the magnetic attraction between the focusing magnet 51 and the magnetic member 54 can assist and guide the installation of the lens 20, thereby enabling the lens 20 to be accurately installed and reducing the difficulty of installing the lens 20.

[0095] In some implementations, the lens 20 extends into the anti-shake carrier 2 and is slidably connected with the anti-shake carrier 2 in the direction of the optical axis. For example, the anti-shake carrier 2 can be provided with a guide rod 50, and the lens 20 can be provided with a sliding groove. The guide rod 50 and the sliding groove are slidably connected in the direction of the optical axis, so that the lens 20 can move more stably in the direction of the optical axis, thereby improving the stability of the focusing movement of the lens 20.

[0096] In some embodiments, as shown in Figure 1 , the motor 10 further comprises a housing 6, which is arranged according to the shape of the anti-shake carrier 2. Therefore, the outer side of the housing 6 is also provided with a step structure 61 corresponding to the step of the anti-shake carrier 2, so as to realize the miniaturization design of the motor 10.

[0097] As Figure 9 shown, the application also proposes a camera module 100.

[0098] According to the camera module 100 of the embodiment of the application, the camera module 100 comprises a lens 20 and the motor 10 of any one of the above embodiments. Figure 9 As shown, the lens 20 is mounted on the motor 10, the lens 20 comprises a lens 201 and a holder 202, the lens 201 is mounted on the holder 202, and the holder 202 is provided with a focusing magnet 51. Figure 1 and Figure 2 As shown, the motor 10 is provided with a mounting port 62, and part of the lens 20 extends into the motor 10 along the mounting direction Z from the mounting port 62.

[0099] It can be understood that the lens 20 of the application is an integrated lens 20, that is, the lens 201 can be embedded in the holder 202, and the outer side of the holder 202 is provided with a mounting position for the focusing magnet 51, which can be a groove or a planar area for bonding the focusing magnet 51, which is not limited here. In this way, in the case that the motor 10 is provided with a focusing coil 52, energizing the focusing coil 52 can drive the focusing magnet 51 to directly drive the lens 20 to move along the direction of the optical axis to achieve focusing. In this way, the camera module 100 of the application does not need to separately provide a focusing carrier, so as to simplify the installation steps and improve the production efficiency. At the same time, the focusing magnet 51 can be directly mounted to the lens 20, so that the arrangement of the lens 20 and the focusing magnet 51 is more compact. In particular, the holder 202 replaces the function of the lens barrel, so that the lens 20 of the application can omit the lens barrel, thereby reducing the radial size of the lens 20 and facilitating the miniaturization design of the lens 20.

[0100] Further, when installing the lens 20 and the motor 10, the lens 201, the holder 202 and the focusing magnet 51 can be regarded as a first module, and the motor 10 can be regarded as a second module. Then, part of the lens 20 extending into the motor 10 along the mounting direction Z from the mounting port 62 can include: controlling the first module and / or the second module to move along the mounting direction Z until the first module extends into the motor 10 from the mounting port 62 to a preset position. The preset position refers to a designed position, which is generally the position of the first module when part of the first module is located in the motor 10 and just abuts against the second module. It can also be other designed positions, as long as the entering depth during assembly is controlled, which is not limited here.

[0101] For example, in some implementations, for example, in the case of an integrated lens 20, when the first module is located above the second module, the mounting direction Z can be the direction of the optical axis Z downward, and the first module can move along the mounting direction Z until it extends into the motor 10. In this way, the first module can move downward from the top of the first module until it extends into the motor 10.

[0102] In this way, when assembling, the lens 20 can be mounted without disassembling the motor 10, so that the assembly process of the lens 20 and the motor 10 is relatively simple, and the assembly efficiency of the camera module 100 is improved.

[0103] It can be understood that the parts of the motor in the related art are not modularized, resulting in a relatively complex assembly step when the lens is assembled with the motor. In the present application, the multiple mechanisms of the camera module 100 are modularized, and when assembling, the first module only needs to be extended into the mounting port 62 along the optical axis direction to complete the assembly with the second module. In this way, the assembly process of the camera module 100 is simplified, and the assembly efficiency of the camera module 100 is improved.

[0104] As shown in Figure 10 The present application also provides an electronic device 1000.

[0105] As shown in Figure 11 The electronic device 1000 according to the embodiments of the present application includes an electronic device body 200, a cover 300, and the camera module 100 of the above embodiments, as shown in Figure 12 The camera module 100 is arranged on the electronic device body 200, the motor 10 is provided with a step, and the cover 300 cooperates with the step.

[0106] It can be understood that when the camera module 100 is mounted on the electronic device body 200, the first part 21 can be embedded in the electronic device body 200, and the second part 22 protrudes from the electronic device body 200. The cover 300 can be arranged on the outside of the second part 22 and the lens 20 to protect the lens 20. If the connection between the first part 21 and the second part 22 does not form a step, the size of the cover 300 needs to be larger than the size of the first part 21. In the present application, the connection between the first part 21 and the second part 22 forms a step, and the shell 6 also correspondingly has a step structure 61. Therefore, the cover 300 only needs to cover the second part 22 with a smaller size. In this way, the size of the cover 300 is reduced, and the overall size of the electronic device 1000 is reduced, and miniaturization design of the electronic device 1000 is facilitated.
