[0001] The present application relates to the field of terminal technology, and in particular to a camera module, a motor structure, and an electronic device. Background Art

[0002] With the development of mobile phone camera technology, the photography effects and demands of consumer electronic products such as mobile phones, tablets, laptops and wearable cameras are increasingly comparable to those of SLR cameras, and the camera function effect has gradually become an important feature of terminal electronic devices and one of the main indicators for evaluating the performance of terminal electronic devices.

[0003] Taking mobile phones as an example, current electronic devices usually have a camera module that includes a lens and a drive motor, wherein the drive motor is the carrier for realizing zoom and focus in the camera module. Usually, the lens is fixed on the drive motor. Under the driving force generated by the drive motor, the lens moves to a specified position, thereby realizing zoom and focus at different magnifications.

[0004] However, when the camera module includes multiple movable lens groups to meet the zoom mode with higher shooting quality, such as continuous zoom mode, the existing driving structure is relatively complex, which affects the movement speed and accuracy of the lens and reduces the zoom effect. Summary of the invention

[0005] The present application provides a camera module, a motor structure, and an electronic device, which solves the problem that the driving structure in the existing camera module is relatively complex, which affects the movement speed and accuracy of the lens and reduces the shooting effect.

[0006] A first aspect of an embodiment of the present application provides a camera module, including a motor structure and a camera assembly, wherein the motor structure includes a base frame, a driving device, and a carrier, wherein the driving device is disposed on the base frame, and the carrier is connected to the driving device;

[0007] The camera assembly comprises a lens and a lens guide rod, wherein the lens guide rod is arranged on the base frame, the lens is slidably connected to the lens guide rod, and the lens is arranged on the carrier.

[0008] In this way, when the driving device drives the carrier to move, it can drive the lens to move along the lens guide rod to achieve zooming or focusing of the lens, etc. Compared with the existing camera assembly, the driving device is connected to the carrier, the lens is set on the carrier, and the lens moves along the lens guide rod under the action of the driving device. It can also be understood that the driving device is set on the lens so that the driving device and the lens are coupled into a whole, and the lens is driven to move along the lens guide rod by the driving device. Compared with the existing motor structure, the slide rail for the movement of the carrier is omitted, the movement system of the lens is simplified, the friction of the lens sliding is effectively reduced, and the movement system of the lens in the camera module is simplified, thereby improving the speed and accuracy of the lens movement, which helps to improve the shooting effect.

[0009] In addition, the camera module with a simplified lens movement system has a simpler layout, better feasibility, and lower cost.

[0010] In a possible implementation of the first aspect, there are multiple camera assemblies, each of which corresponds to one driving device and one carrier, and among the two camera assemblies, the lens of one camera assembly is slidably connected to the lens guide rod of the other camera assembly.

[0011] In this way, the movement of multiple lens groups can be realized, and the lens movement system is simplified by the above method, which significantly improves the speed and accuracy of lens movement. For example, there can be two camera components, and two driving devices are arranged on the base frame of the motor structure, and the two driving devices are respectively connected to the bearing seats, and each bearing seat is provided with a camera component.

[0012] In a possible implementation manner of the first aspect, a first magnetic body is disposed on the carrier, a second magnetic body is disposed on the lens, and the first magnetic body and the second magnetic body attract each other.

[0013] In this way, through the attraction between the first magnetic body and the second magnetic body, the lens can be set on the carrier to achieve the coupling of the camera assembly and the driving device, thereby normalizing the movement reference mode of the driving device and the lens and improving the movement speed and accuracy of the lens.

[0014] In a possible implementation manner of the first aspect, a clamping member is provided on one of the carrier and the lens, a clamping slot is provided on the other of the carrier and the lens, and the clamping member and the clamping slot are positioned and matched.

[0015] In this way, a clamp can be provided on the lens, and a slot can be provided on the carrier. The clamp can be positioned and matched with the slot to achieve a matched connection between the lens and the carrier. At the same time, the matching between the clamp and the slot can facilitate the positioning of the lens and the carrier during installation, and facilitate the assembly of the lens and the carrier.

[0016] In a possible implementation manner of the first aspect, the driving device includes a driving coil, a first driving magnet, and an annular first magnetic shielding structure;

[0017] Part of the first magnetic shielding structure passes through the center of the drive coil, the first drive magnet is located in the first magnetic shielding structure and on one side of the drive coil, and the magnetic flux lines of the first drive magnet are perpendicular to the drive coil, the first drive magnet and the first magnetic shielding structure are fixedly connected to the carrier, and the drive coil is arranged on the base.

[0018] In this way, there is a magnetic field at one end of the driving coil close to the first driving magnet. At the same time, a circular current will be formed when the driving coil is energized, and an Ampere force will be generated in the magnetic field of the vertical coil. The Ampere force serves as a driving force, enabling the first driving magnet and the first magnetic shielding structure to move back and forth through the driving coil. The first driving magnet and the first magnetic shielding structure are fixedly connected to the carrier, and the driving coil is arranged on the base. In this way, the carrier can be driven to move linearly relative to the base, and then the lens on it can be driven to move along the lens guide rod through the carrier, thereby realizing long-stroke focusing or zooming of the camera module.

[0019] In a possible implementation manner of the first aspect, the driving device further includes a second magnetic shielding structure parallel to the first magnetic shielding structure, and a portion of the second magnetic shielding structure passes through a center of the driving coil;

[0020] A second driving magnet is arranged in the second magnetic shielding structure. The second driving magnet is located on one side of the driving coil. The magnetic flux lines of the second driving magnet are perpendicular to the driving coil, and the directions of the magnetic flux lines of the first driving magnet and the second driving magnet are opposite. The second driving magnet and the second magnetic shielding structure are fixedly connected to the carrier.

[0021] In this way, a magnetic field will also be generated at one end of the driving coil close to the second driving magnet. After being energized, the driving coil will form a circular current, thereby generating an Ampere force in the magnetic field of the vertical coil. The Ampere force can also be used as a driving force. The magnetic pole directions of the first driving magnet and the second driving magnet can be controlled so that the directions of the magnetic flux lines of the first driving magnet and the second driving magnet are opposite, thereby generating Ampere forces in the same direction on both sides of the driving coil as a driving force, so as to drive the carrier to move in a straight line, effectively improving the driving force of the driving device, and helping to improve the movement speed and accuracy of the lens.

[0022] In a possible implementation manner of the first aspect, the motor structure further includes a position detection device, and the position detection device is used to detect the moving position of the carrier.

[0023] The position detection device detects the moving position of the carrier, and thus can detect the moving position of the lens, so as to determine how the lens should move or whether it has moved to the desired position, so as to achieve closed-loop control of the motor structure.

[0024] In a possible implementation of the first aspect, the position detection device includes a detection component and a sensing magnet, the sensing magnet is disposed on the carrier, the detection component is disposed on the base, and the detection component is used to detect the magnetic field of the sensing magnet.

[0025] When the driving device drives the carrier to move, the sensing magnet will also move with the carrier, so that the distance between the sensing magnet and the detection component will change, and the magnetic field of the sensing magnet detected by the detection component will also change. Through this change, the movement position of the carrier can be detected, and then the movement position of the lens can be detected.

[0027] The motor structure includes a base frame, a driving device, and a carrier, wherein the driving device is fixed on the base frame, the carrier is connected to the driving device, the carrier is used to carry the camera of the camera assembly, and the driving device is used to drive the lens to move along the lens guide rod of the camera assembly. That is, the driving device is coupled to the lens through the carrier seat to form a whole, and the lens is driven to move along the lens guide rod by the driving device, thereby eliminating the slide rail for moving the carrier, simplifying the motor structure, and then simplifying the movement system of the lens, thereby improving the movement speed and accuracy of the lens and enhancing the shooting effect.

[0028] In a possible implementation manner of the second aspect, a slide rail is further included, which is detachably arranged on the base frame, and the carrier is slidably arranged on the slide rail. When the carrier carries the lens, the slide rail is detached from the base frame.

[0029] That is, the motor structure can be provided with a slide rail for the carrier to slide in a detachable manner. When the camera assembly is connected to the motor structure, the slide rail can be removed from the base frame when the lens is supported on the carrier, thereby achieving the purpose of simplifying the lens motion system. When the motor structure does not support the lens, it includes a slide rail, and the driving device can drive the carrier to slide on the slide rail, so that the motion performance of the motor structure can be easily tested, and the test and adjustment can be carried out in time to ensure the driving effect of the motor structure.

[0050] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0051] In recent years, the shooting effect of electronic devices such as smartphones has become an increasingly important factor for consumers to consider when purchasing smartphones, and has also become an important selling point for mobile phone manufacturers to compete for the market. Therefore, the performance of mobile phone camera modules has become increasingly important. Among them, telephoto lenses are deeply loved by consumers due to their excellent long-range shooting effects. Taking mobile phones as an example, existing mobile phone telephoto camera modules usually adopt a periscope architecture design. Compared with fixed-focus telephoto lenses, continuous zoom lenses add a ZOOM lens group on the basis of the AF focus lens group, which contains two groups of movable lens groups, making the optical system of the entire module more complex.

[0052] Among them, the driving motor is the carrier of the camera module to achieve zoom and focus. Driven by the motor thrust, the lens moves to the specified position along with the movement of the motor carrier, thereby achieving zoom and focus at different magnifications. In the continuous zoom module, there is more than one movable lens group, and the moving stroke of the lens is larger and the precision requirement is also higher. In the existing camera module, the motor structure usually includes a driving device, a carrier and a slide rail. The driving device can drive the carrier to move on its slide rail, wherein the lens of the camera module is arranged on the carrier, and the lens can be slidably arranged on the moving guide rail of the lens. The driving device can drive the lens to move along its moving guide rail through the carrier. However, when multiple lens groups need to move, multiple guide rails will appear in the motor structure, and the motor structure becomes more complicated, resulting in the complication of the lens movement system in the entire camera module, thereby affecting the movement speed and movement accuracy of the lens and reducing the shooting effect.

[0053] Based on the above technical problems, the embodiments of the present application provide a camera module, a motor structure, and an electronic device. The camera module connects a driving device and a carrier, and the lens is arranged on the carrier, and the lens is slidably connected to the lens guide rod. When the driving device drives the carrier to move, it can drive the lens to move along the lens guide rod to achieve focusing and zooming of the lens. That is, the driving device is arranged on the lens so that the driving device and the lens are coupled as a whole, and the lens is driven to move along the lens guide rod by the driving device, thereby eliminating the slide rail for moving the carrier, reducing the friction of the lens sliding, simplifying the movement system of the lens in the camera module, thereby improving the speed and accuracy of the lens movement, and helping to improve the shooting effect.

[0054] The following is a detailed description of a camera module, motor structure, and electronic equipment provided in an embodiment of the present application in conjunction with the accompanying drawings.

[0055] Figure 1 A schematic diagram of the structure of a camera module provided in an embodiment of the present application.

[0056] See also Figure 1 As shown, a camera module 100 provided in an embodiment of the present application includes a motor structure 10 and a camera assembly 20, wherein the motor structure 10 includes a base frame 11, a driving device 12, and a carrier 13, the driving device 12 is arranged on the base frame 11, and the carrier 13 is connected to the driving device 12, so that the driving force generated by the driving device 12 can drive the carrier 13 to move.

[0057] The camera assembly 20 includes a lens 21 and a lens guide rod 22. The lens guide rod 22 is set on the base frame 11. The lens 21 is slidably connected to the lens guide rod 22, and the lens 21 is set on the carrier 13. In this way, when the driving device 12 drives the carrier 13 to move, it can drive the lens 21 to move along the lens guide rod 22 to achieve zooming or focusing of the lens 21. Compared with the existing camera assembly 20, the driving device 12 is connected to the carrier 13, the lens 21 is arranged on the carrier 13, and the lens 21 moves along the lens guide rod 22 under the action of the driving device 12. It can also be understood that the driving device 12 is arranged on the lens 21, so that the driving device 12 and the lens 21 are coupled into a whole, and the lens 21 is driven by the driving device 12 to move along the lens guide rod 22. Compared with the existing motor structure 10, the slide rail 14 for moving the carrier 13 is omitted, the movement system of the lens 21 is simplified, the friction of the sliding of the lens 21 is effectively reduced, and the movement system of the lens 21 in the camera module 100 is simplified, thereby improving the speed and accuracy of the movement of the lens 21, which helps to improve the shooting effect.

[0058] In addition, the camera module 100 with a simplified lens 21 motion system has a simpler layout, better feasibility, and lower cost.

[0059] There may be multiple camera assemblies 20, each of which corresponds to a driving device 12 and a carrier 13, that is, a camera assembly 20 may be provided on a carrier 13, and the camera assembly 20 is driven by a driving device 12, so that the movement of multiple groups of lenses 21 can be realized.

[0060] Among them, in the two camera assemblies 20, the lens 21 of one camera assembly 20 is slidingly connected to the lens guide rod 22 of the other camera assembly 20, and one lens 21 is set on the two lens guide rods 22 and moves along the two lens guide rods 22, which helps to improve the stability of the movement of the lens 21.

[0061] For details, see Figure 1 As shown, the camera assembly 20 includes two (combined Fig. 9 ), respectively a first camera assembly and a second camera assembly, wherein the first camera assembly includes a first lens and a first lens guide rod, and the second camera assembly includes a second lens and a second lens guide rod. One end of the first lens is slidably connected to the first lens guide rod, the other end of the first lens is slidably connected to the second lens guide rod, one end of the second lens is slidably connected to the second lens guide rod, and the other end of the second lens is slidably connected to the first lens guide rod, so that the first lens and the second lens both move along the first lens guide rod and the second lens guide rod, thereby improving the stability of the movement of the first lens and the second lens.

[0062] In addition, when there are multiple camera components, that is, the camera components include multiple groups of lenses that need to be moved, the lens movement system of the camera module becomes more complicated. The camera module provided in the embodiment of the present application can simplify the lens movement system in the above manner, thereby significantly improving the speed and accuracy of the lens movement.

[0063] For details, see Figure 1 As shown, taking two camera assemblies 20 as an example, two driving devices 12 are arranged on the base frame 11 of the motor structure 10, and the two driving devices 12 are respectively connected to the carrier 13, wherein the first carrier is provided with a first lens, and the second carrier is provided with a second lens, one end of the first lens is slidably connected to the first lens guide rod, and the other end of the first lens is slidably connected to the second lens guide rod, one end of the second lens is slidably connected to the second lens guide rod, and the other end of the second lens is slidably connected to the first lens guide rod. Compared with the case where the motor structure 10 has a slide rail 14, specifically, each slide rail 14 corresponds to a carrier 13, and the combination Figure 7As shown, it includes a first slide rail and a second slide rail, a first carrier is slidably connected to the first slide rail, and a second carrier is slidably connected to the second slide rail. After the motor structure 10 and the camera assembly 20 are assembled, the movement of the first lens is related to the first slide rail, the first lens guide rod, the second lens guide rod and the second slide rail, and correspondingly, the movement of the second lens is related to the second slide rail, the second lens guide rod, the first lens guide rod and the first slide rail, and the movement system of the lens is relatively complicated.

[0064] In the embodiment of the present application, the slide rail 14 connected to the carrier body in the motor structure 10 is removed. Thus, after the motor structure 10 and the camera assembly 20 are assembled, the movement of the first lens is related to the first lens guide rod and the second lens guide rod, and the movement of the second lens is related to the second lens guide rod and the first lens guide rod, which significantly reduces the friction of the sliding of the lens 21, simplifies the movement system of the lens 21, and effectively improves the speed and accuracy of the movement of the lens 21.

[0065] Figure 2 A schematic diagram of the assembly of a carrier and a lens in a camera module provided in an embodiment of the present application.

[0066] Among them, see Figure 2 As shown, in the embodiment of the present application, a first magnetic body 131 is provided on the carrier 13, and a second magnetic body 211 is provided on the lens 21. The first magnetic body 131 and the second magnetic body 211 attract each other. In this way, through the attraction between the first magnetic body 131 and the second magnetic body 211, the lens 21 can be set on the carrier 13, and the coupling of the camera assembly 20 and the driving device 12 is realized, so that the movement reference mode of the driving device 12 and the lens 21 is normalized, and the movement speed and accuracy of the lens 21 are improved.

[0067] A card member may be provided on one of the carrier 13 and the lens 21, and a card slot may be provided on the other of the carrier 13 and the lens 21. For example, in the embodiment of the present application, see Figure 2 As shown, a clamp 212 may be provided on the lens 21, and a slot 132 may be provided on the carrier 13. The clamp 212 may be positioned and matched with the slot 132 to achieve a matched connection between the lens 21 and the carrier 13. Meanwhile, the matching between the clamp 212 and the slot 132 may facilitate the positioning of the lens 21 and the carrier 13 during installation, and facilitate the assembly of the lens 21 and the carrier 13.

[0068] Specifically, the clamping member 212 may be a protrusion formed on a surface of the lens 21 facing the carrier 13 , and the clamping groove 132 may be a groove formed on a surface of the carrier 13 facing the lens 21 .

[0069] Among them, after the lens 21 is set on the carrier 13 by means of the above-mentioned first magnetic body 131, the second magnetic body 211, the clamp 212 and the clamping slot 132, the lens 21 and the carrier 13 can be further fixed by the adhesive layer to enhance the connection strength between the lens 21 and the carrier 13, thereby ensuring the setting stability of the lens 21 and helping to improve the shooting effect of the lens 21.

[0070] Figure 3 A schematic diagram of the side view structure of a camera module provided in an embodiment of the present application.

[0071] See also Figure 3 As shown, in the embodiment of the present application, the motor structure 10 also includes a position detection device 15, which is used to detect the moving position of the carrier 13, that is, the moving position of the lens 21 can be detected, so as to determine how the lens 21 should move or whether it has moved to the desired position, so as to realize closed-loop control of the motor structure 10.

[0072] For details, see Figure 3 As shown, the position detection device 15 may include a detection component 151 and a sensing magnet 152, wherein the sensing magnet 152 is disposed on the carrier 13, the detection component 151 is disposed on the base frame 11, and the detection component 151 is used to detect the magnetic field of the sensing magnet 152. When the driving device 12 drives the carrier 13 to move, the sensing magnet 152 will also move with the carrier 13, so that the distance between the sensing magnet 152 and the detection component 151 will change, and the magnetic field of the sensing magnet 152 detected by the detection component 151 will also change. Through this change, the moving position of the carrier 13 can be detected, and then the moving position of the lens 21 can be detected.

[0073] In addition, the detection component 151 is arranged on the base frame 11, and the driving coil 121 of the driving device 12 can also be arranged on the base frame 11, and the sensing magnet 152 is arranged on the supporting seat. In this way, the part of the motor structure 10 that needs to be powered is fixedly arranged on the base frame 11, forming a moving magnetic motor structure, which simplifies the structural form of the motor structure 10 and reduces the difficulty of realizing the motor structure 10.

[0074] Figure 4 A schematic diagram of the structure of a driving device provided in an embodiment of the present application is shown in FIG. Figure 5 A partially enlarged view of a driving device provided in an embodiment of the present application.

[0075] In the present application examples, see Figure 4As shown, the driving device 12 includes a driving coil 121, a first driving magnet 122 and an annular first magnetic shielding structure 123, wherein a portion of the first magnetic shielding structure 123 passes through the center of the driving coil 121, and the first driving magnet 122 is located in the first magnetic shielding structure 123 and on one side of the driving coil 121.

[0076] See also Figure 5 As shown, the first driving magnet 122 can form a magnetic flux line (such as Figure 5 In the B direction), the end of the driving coil 121 close to the first driving magnet 122 has a magnetic field. At the same time, the driving coil 121 will form a ring current (such as Figure 5 In the direction (in the middle I direction), an Ampere force will be generated in the magnetic field of the vertical coil, and the Ampere force will serve as a driving force, so that the first driving magnet 122 and the first magnetic shielding structure 123 can reciprocate through the driving coil 121. The first driving magnet 122 and the first magnetic shielding structure 123 are fixedly connected to the carrier 13, and the driving coil 121 is arranged on the base 11, so that the carrier 13 can be driven to move linearly relative to the base 11, and then the carrier 13 drives the lens 21 thereon to move along the lens guide rod 22, so as to realize long-stroke focusing or zooming of the camera module 100.

[0077] The molding material of the magnetic shielding structure may be a material with excellent magnetic conductivity.

[0079] See also Figure 6As shown, in the embodiment of the present application, the driving device 12 may further include a second magnetic shielding structure 125 parallel to the first magnetic shielding structure 123. The first magnetic shielding structure 123 and the second magnetic shielding structure 125 may form a double-circular structure, and a portion of the second magnetic shielding structure 125 passes through the center of the driving coil 121. A second driving magnet 124 is arranged in the second magnetic shielding structure 125. The second driving magnet 124 forms magnetic flux lines perpendicular to the driving coil 121 through the magnetizing effect. The end of the driving coil 121 close to the second driving magnet 124 will also generate a magnetic field. The driving coil 121 will form a circular current after being energized, thereby generating an Ampere force in the magnetic field perpendicular to the coil. The Ampere force can also be used as a driving force. The magnetic pole directions of the first driving magnet 122 and the second driving magnet 124 can be controlled so that the directions of the magnetic flux lines of the first driving magnet 122 and the second driving magnet 124 are opposite, thereby generating Ampere forces in the same direction on both sides of the driving coil 121 as a driving force, so as to drive the carrier 13 to move in a straight line, thereby effectively improving the driving force of the driving device 12, which helps to improve the movement speed and accuracy of the lens 21.

[0080] Combination Figure 1 As shown, the camera module 100 may further include a power supply device 16 , which may be connected to the driving coil 121 to supply power to the driving coil 121 .

Figure 8 A side view schematic diagram of a motor structure is provided for an embodiment of the present application. Fig. 9 A schematic diagram of the structure of a camera assembly provided in an embodiment of the present application.

[0082] The embodiment of the present application also provides a motor structure 10 for driving the camera assembly 20 to move so as to achieve focusing or zooming of the camera. The motor structure 10 and the camera assembly 20 are assembled together to form the above-mentioned camera module 100. The motor structure 10 can be applied to a periscope telephoto module to achieve long-stroke focusing of the module.

[0083] For details, see Figure 7 and Figure 8As shown, it includes a base frame 11, a driving device 12, and a carrier 13. The driving device 12 is fixedly arranged on the base frame 11, and the carrier 13 is connected to the driving device 12. The carrier 13 is used to carry the lens 21 of the camera assembly 20. The driving device 12 is used to drive the lens 21 to move along the lens guide rod 22 of the camera assembly 20. In this way, the driving device 12 drives the carrier 13 to move, which can drive the lens 21 to move along the lens guide rod 22 to achieve zooming or focusing of the lens 21. That is, the driving device 12 is coupled to the lens 21 through the bearing seat to form a whole, and the lens 21 is driven to move along the lens guide rod 22 by the driving device 12, thereby eliminating the slide rail 14 for the carrier 13 to move, simplifying the motor structure 10, and then simplifying the motion system of the lens 21, thereby improving the movement speed and accuracy of the lens 21 and improving the shooting effect.

[0084] Among them, see Figure 7 and Figure 8 As shown, the motor structure 10 may further include a slide rail 14, which may be detachably arranged on the base frame 11, and the carrier 13 may be slidably arranged on the slide rail 14. When the carrier 13 carries the lens 21, the slide rail 14 may be detached from the base frame 11. That is, the motor structure 10 may be detachably arranged with the slide rail 14 for the carrier 13 to slide, and the slide rail 14 may be detachably arranged on the motor structure 10. Fig. 9 and Figure 1 As shown, when the camera assembly 20 is connected to the motor structure 10 and the lens 21 is supported and set on the supporting body 13, the slide rail 14 can be removed from the base frame 11, thereby achieving the purpose of simplifying the movement system of the lens 21.

[0085] When the motor structure 10 is not carrying the lens 21 , it includes a slide rail 14 , and the driving device 12 can drive the carrier 13 to slide on the slide rail 14 , so that the motion performance of the motor structure 10 can be easily tested to ensure the driving effect of the motor structure 10 .

[0086] The motor structure 10 may include a plurality of slide rails 14, which are arranged on the base frame 11, each slide rail 14 corresponds to a carrier 13 and a driving device 12, and each carrier 13 may carry at least one set of lenses 21. In this way, the movement of multiple sets of lenses can be realized, which can be applied to a long-stroke zoom module, can effectively simplify the motion system of the lens, and improve the speed and accuracy of the lens movement.

[0087] Combination Figure 7 and Fig. 9 As shown, a first magnetic body 131 can be provided on the carrier 13 of the motor structure 10 , and a second magnetic body 211 can be provided on the lens 21 of the camera assembly 20 .

[0088] A card slot 132 may also be provided on the carrier 13, and a pull piece that can be positioned and matched with the card slot 132 may be provided on the lens 21 to achieve the matching connection between the lens 21 and the carrier 13. In this way, through the attraction between the first magnetic body 131 and the second magnetic body 211 and the matching of the card piece 212 and the card slot 132, the lens 21 is fixedly connected to the carrier 13, thereby realizing the coupling of the camera assembly 20 and the driving device 12.

[0089] When the motor structure 10 and the camera assembly 20 are assembled, the first magnetic body 131 and the second magnetic body 211 respectively disposed on the lens 21 and the carrier 13 are attracted to each other, and the clamping member 212 on the lens 21 and the clamping groove 132 on the carrier 13 are positioned and matched, so that the lens 21 is fixedly disposed on the carrier 13. Then, the lens 21 and the carrier 13 can be fixed by an adhesive layer, and finally the slide rail 14 in the motor structure 10 is removed to simplify the structure of the motor structure 10 and simplify the lens motion system.

[0090] See also Figure 8 As shown, the motor structure 10 may further include a position detection device 15 for detecting the moving position of the carrier 13 and further detecting the moving position of the lens 21 .

[0091] Specifically, the position detection device 15 may include a detection component 151 and a sensing magnet 152, wherein the sensing magnet 152 may be set on the carrier 13, and the detection component 151 may be set on the base frame 11, and the detection component 151 is used to detect the magnetic field of the sensing magnet 152, so as to realize the detection of the moving position of the carrier 13 according to the change of the magnetic field of the sensing magnet 152.

[0092] In the embodiment of the present application, the driving device 12 of the motor structure 10 may include a driving coil 121, a first driving magnet 122 and an annular first magnetic shielding structure 123, wherein a portion of the first magnetic shielding structure 123 passes through the center of the driving coil 121, the first driving magnet 122 is located in the first magnetic shielding structure 123 and is located on one side of the driving coil 121, the magnetic flux lines of the first driving magnet 122 are perpendicular to the driving coil 121, so that there is a magnetic field at one end of the driving coil 121 close to the first driving magnet 122, and the Ampere force generated after the driving coil 121 is energized can be used as a driving force to drive the carrier 13 to move, and then the lens 21 thereon is driven by the carrier 13 to move along the lens guide rod 22, thereby realizing long-stroke focusing or zooming of the camera module 100.

[0093] The driving device 12 may also include a second magnetic shielding structure 125 parallel to the first magnetic shielding structure 123, and a portion of the second magnetic shielding structure 125 passes through the center of the driving coil 121. A second driving magnet 124 is arranged in the second magnetic shielding structure 125, and the magnetic flux lines of the second driving magnet 124 are perpendicular to the driving coil 121. The end of the driving coil 121 close to the second driving magnet 124 will also generate a magnetic field. The driving coil 121 will generate an Ampere force after being energized. By controlling the magnetic pole directions of the first driving magnet 122 and the second driving magnet 124, the Ampere force in the same direction is generated on both sides of the driving coil 121 as a driving force to drive the carrier 13 to move in a straight line, which effectively improves the driving force of the driving device 12 and helps to improve the movement speed and accuracy of the lens 21.

[0094] See also Figure 8 As shown, the camera module 100 may further include a power supply device 16 , which may be connected to the driving coil 121 to supply power to the driving coil 121 .
