Description

Technical Field

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

[0002] With the rapid development of self-media, people have higher and higher requirements on the cameras of electronic products such as mobile phones, tablets, laptops and wearable cameras. The photo-taking effect and demand 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 a mobile phone as an example, the current electronic device usually has a camera module including a lens and a drive motor, wherein the drive motor is a carrier for realizing focus and anti-shake in the camera module, and the lens is usually fixed on the drive motor. Under the driving force generated by the drive motor, the lens moves to a specified position, thereby realizing the focus and anti-shake functions. Usually, the slide rail drive motor includes a base, a carrier, a guide rod, a magnet and a drive coil; wherein the coil is fixed on the base, the magnet is arranged on the carrier, and the magnet and the coil are arranged relative to each other, the guide rod is arranged between the carrier and the base, and the guide rod is fixed on the base by glue bonding or welding, and the carrier and the guide rod are slidably connected. When in use, when a certain amount of current is passed through the drive coil, a corresponding force will be generated between the drive coil and the magnet, driving the carrier to move along the guide rod to realize the function of automatic focusing.

[0004] However, the existing camera modules have complex structures and complicated assembly procedures, and cannot meet people's increasingly high requirements for camera modules. Summary of the invention

[0005] The present application provides a camera motor, a camera module and an electronic device. The camera motor has a simple structure and a high degree of component integration, which can reduce the difficulty of assembly and solve the problems of complex driving motor structure and cumbersome assembly process in existing camera modules.

[0006] A first aspect of an embodiment of the present application provides a camera motor for driving the movement of the lens of a camera module, the camera motor comprising a base frame, a carrier and a first driving assembly. The carrier is movably arranged on the base frame, and the carrier is used to carry the lens of the camera module. A guide rail along the optical axis direction of the lens is integrally formed on one of the carrier and the base frame, and a guide groove cooperating with the guide rail is provided on the other of the carrier and the base frame. A guide rail is provided in each of the guide grooves, and the guide rail and the guide groove are movably connected in the extension direction of the guide rail. The first driving assembly is arranged between the base frame and the carrier, and the first driving assembly is used to drive the carrier to move on the base frame.

[0007] The camera motor in the embodiment of the present application is formed with a guide rail along the optical axis of the lens on one of the carrier and the base, and a guide groove cooperating with the guide rail is provided on the other of the carrier and the base. In this way, the guide rail and the guide groove can be formed integrally on the carrier or the base, respectively. In particular, the guide rail is formed integrally on the carrier or the base. This can reduce the parts of the camera motor and reduce the cost while ensuring that the carrier can move relative to the base along the optical axis of the lens. Compared with setting the guide rail separately, this can simplify the camera motor and simplify the assembly process. This solves the problem of complex drive motor structure and cumbersome assembly process in the related art. In addition, by forming the guide rail integrally on the carrier or the base, reliability failure problems such as loosening and falling off of the guide rail can also be solved.

[0008] In a possible implementation, a limiting portion is provided on one of the guide rail and the guide groove, and the other of the guide rail and the guide groove abuts against the limiting portion. Three limiting portions are provided between the plurality of guide rails and the plurality of guide grooves. At least one limiting portion is provided between each guide groove and the guide rail located in the guide groove. The three limiting portions form a stable plane.

[0009] By setting the limiter, the freedom of the guide rail when moving in the guide groove can be limited, so that the carrier can move along the extension direction of the guide rail in a stable plane, which can avoid the shaking of the lens on the carrier, ensure that the optical axis of the lens is always in the same straight line, prevent the lens from shaking, and ensure the shooting quality. In addition, the simple structure of the limiter can simplify the structure of the camera motor and reduce the cost.

[0010] In a possible implementation, the limiting portion is disposed in the guide groove, wherein the limiting portion is a protruding structure protruding outward from an inner wall of the guide groove.

[0011] By providing the limiting portion as a protruding structure, the structure of the limiting portion can be simplified and the processing cost can be reduced.

[0012] In a possible implementation, part of the guide rails is a split structure, and the guide rails are the limiting portions.

[0013] By arranging the guide rail as a split structure and using the guide rail as a limiting part, the structure of the guide groove can be simplified, the production is convenient, and the cost is reduced.

[0014] In a possible implementation, the number of the guide rails and the guide grooves are both two. The two guide rails or the guide grooves are arranged at diagonal positions of the base frame, and the line connecting the two guide rails passes through the optical axis of the lens. Alternatively, the two guide rails or the guide grooves are arranged on the same surface of the base frame, and the two guide rails are arranged at intervals.

[0015] By arranging two guide rails and guide grooves at diagonal positions of the base frame, and with the line connecting the two guide rails passing through the optical axis of the lens, the torque of the carrier when it moves under force can be reduced, and the carrier can be effectively prevented from flipping when it moves along the optical axis of the lens.

[0016] By arranging two guide rails or guide grooves on the same surface of the base frame, it is possible to adapt to the structures of different types of camera motors and provide a reasonable setting space for the layout of other components of the camera motor.

[0017] In a possible implementation, when the two guide rails or the guide grooves are arranged at diagonal positions of the base frame, and the line connecting the two guide rails passes through the optical axis of the lens, there are two first drive assemblies, wherein one side of each guide rail is provided with a first drive assembly, and the two first drive assemblies are respectively located on two adjacent side walls of the base frame.

[0018] By arranging a first driving assembly on one side of each guide rail, the driving force can be increased and dispersed in different areas. Compared with arranging the first driving assembly at one position, this can reduce the torque of the carrier when it is driven, thereby preventing the carrier from flipping when moving along the optical axis direction of the lens.

[0019] In a possible implementation, when the two guide rails or the guide grooves are arranged on the same surface of the base frame and the two guide rails are arranged at an interval, there is one first drive assembly, the first drive assembly is arranged between the two guide rails, and is located on the side wall of the base frame between the two guide rails. Alternatively, when the two guide rails or the guide grooves are arranged on the same surface of the base frame and the two guide rails are arranged at an interval, there are two first drive assemblies, one first drive assembly is arranged above each guide rail, and the two first drive assemblies are respectively located on two opposite side walls of the base frame.

[0020] By setting the first drive component between two guide rails or guide grooves, a balanced driving force can be generated on both sides of the carrier, and the carrier can be prevented from flipping when moving along the optical axis of the lens. The structure of the camera motor can be simplified, the assembly process can be simplified, and a reasonable setting space can be provided for the layout of other components of the camera motor.

[0021] By arranging a first driving component on the outer side of each guide rail, the driving force can be increased and dispersed in different areas. Compared with arranging the driving component in one position, this can increase the torque of the carrier when it is driven, thereby preventing the carrier from shifting when it moves along the optical axis of the lens.

[0022] In a possible implementation, the guide rail is formed on the carrier or the base frame by one-shot injection molding, or the guide rail is formed on the carrier or the base frame by two-shot injection molding, or the guide rail is formed on the carrier or the base frame by insert injection molding.

[0023] By molding the guide rail on the carrier or the base frame through one-time injection molding, for example, when the guide rail and the carrier or the base frame are made of the same material, the one-time injection molding can simplify the processing technology of the carrier or the base frame, thereby reducing the cost.

[0024] By secondary injection molding the guide rail on the carrier or the base, for example, the carrier and the base can be molded separately first, and then the guide rail can be secondary injection molded on the carrier or the base. In this case, the material of the guide rail can be polyetheretherketone (PEEK), polyphenylene sulfide (PPS plastic), liquid crystal polymer (LCP) and other materials with relatively high hardness, relatively low friction coefficient and wear resistance, and the carrier and the base can be other insulating materials.

[0025] By injection molding the guide rail together with the carrier or the base in the form of an insert, the guide rail can be set to a metal or ceramic material, which can increase the strength and rigidity of the guide rail. For example, when the guide rail is made of metal and the carrier and the base are made of plastic, the metal guide rail can be directly injection molded as an insert with the carrier or the base into a single structure.

[0026] In a possible implementation, the guide rail and the carrier or the base are made of the same material, and both are insulating materials; the guide rail is formed on the carrier or the base by one-time injection molding.

[0027] In a possible implementation, the first driving component includes a first magnetic element and a first coil, wherein the first coil is disposed on the base frame, the first magnetic element is disposed on the carrier, the first magnetic element and the first coil are disposed opposite to each other, and when the first coil is energized, the first magnetic element is driven to move, thereby driving the carrier to move.

[0028] By setting the first driving component to a structure including a first magnetic element and a first coil, the first magnetic element can generate a driving force when the first coil is energized, and the moving direction and distance of the carrier can be adjusted by adjusting the current in the first coil. In addition, the structures of the magnetic element and the coil are relatively simple and easy to set up. Therefore, this can simplify the structure of the camera motor and reduce costs.

[0029] In a possible implementation, a receiving cavity for receiving the lens is formed in the middle of the carrier, and a plurality of the guide rails or the guide grooves are arranged at intervals on the outside of the receiving cavity.

[0030] By providing a receiving cavity on the carrier, a mounting position is provided for the lens of the camera module so that the lens can be fixed on the carrier. In addition, by providing a receiving cavity, the lens can be hidden in the carrier, so that the carrier can protect the lens, thereby increasing the service life of the lens. By providing multiple guide rails or guide grooves, compared with providing only one guide rail or guide groove, multiple positions of the carrier can be supported, which can reduce the pressure on the individual guide rails and guide grooves, thereby preventing deformation or breakage caused by excessive local force on the guide rails, extending the service life of the guide rails, and thereby extending the service life of the camera motor.

[0031] In a possible implementation, the guide rail includes a first guide rail and a second guide rail, the guide groove includes a first guide groove and a second guide groove, the first guide rail is cooperatively connected to the first guide groove, and the second guide rail is cooperatively connected to the second guide groove.

[0032] In a possible implementation, the camera motor further includes an anti-shake bracket, an adapter frame, and a second drive assembly, wherein the adapter frame and the anti-shake bracket are stacked, and the adapter frame, the anti-shake bracket, and the second drive assembly are all arranged on a side of the base frame away from the carrier.

[0033] The adapter is located between the anti-shake bracket and the base frame, the adapter frame and the base frame are movably connected in a first direction, and the adapter frame and the anti-shake bracket are movably connected in a second direction.

[0034] The first direction, the second direction and the extending direction of the guide rail are perpendicular to each other.

[0035] The second driving assembly is arranged between the anti-shake bracket and the base frame, and the second driving assembly is used for driving the base frame to move.

[0036] By providing an anti-shake bracket, an adapter frame and a second driving component, the camera module with the driving motor can have an optical anti-shake function, so that handheld shooting will not produce blur, thereby improving the performance of the camera module.

[0037] In a possible implementation, a first guide rod extending along the first direction is integrally formed on one of the adapter frame and the base frame, and a first slide groove corresponding to the first guide rod is formed on the other of the adapter frame and the base frame, each of the first slide grooves is provided with a first guide rod, and the first guide rod and the first slide groove are movably connected along the first direction.

[0038] A second guide rod extending along the second direction is integrally formed on one of the adapter frame and the anti-shake bracket, and a second slide groove corresponding to the second guide rod is formed on the other of the adapter frame and the anti-shake bracket, each of the second slide grooves is provided with a second guide rod, and the second guide rod and the second slide groove are movably connected along the second direction.

[0039] By integrally forming the first guide rod or the second guide rod on the adapter frame, the base frame or the anti-shake bracket, a separately set guide rod can be eliminated. Compared with a structure in which a separate guide rod is set and then glued or welded in a slide groove, the connection relationship between the guide rod and the adapter frame, the base frame or the anti-shake bracket is more stable, which can prevent the guide rod from falling off, simplify the structure of the adapter frame, the base frame and the anti-shake bracket, and can simplify the assembly process, reduce the difficulty of assembly, and reduce costs.

[0040] In a possible implementation, the first guide rod or the second guide rod is formed on the adapter frame, the anti-shake bracket or the base frame by one-time injection molding. Alternatively, the first guide rod or the second guide rod is formed on the adapter frame, the anti-shake bracket or the base frame by two-time injection molding. Alternatively, the first guide rod or the second guide rod is formed on the adapter frame, the anti-shake bracket or the base frame by insert injection molding.

[0041] By injecting the first guide rod or the second guide rod onto the adapter frame, the anti-shake bracket or the base frame through one-time injection molding, for example, when the first guide rod or the second guide rod and the adapter frame, the anti-shake bracket or the base frame are made of the same material, the processing technology of the adapter frame, the anti-shake bracket or the base frame can be simplified through one-time injection molding, thereby reducing costs.

[0042] By molding the first guide rod or the second guide rod on the adapter frame, the anti-shake bracket or the base frame by secondary injection molding, for example, the adapter frame, the anti-shake bracket, the base frame, the first guide rod or the second guide rod can be molded separately first, and then the first guide rod or the second guide rod can be molded on the adapter frame, the anti-shake bracket or the base frame by secondary injection molding. In this case, the material of the first guide rod or the second guide rod can be polyetheretherketone (PEEK), polyphenylene sulfide (PPS plastic), liquid crystal polymer (LCP) and other materials with relatively high hardness and relatively low friction coefficient, and the adapter frame, the anti-shake bracket or the base frame can be other insulating materials.

[0043] By injection molding the first guide rod or the second guide rod together with the adapter, the anti-shake bracket or the base in the form of an insert, the first guide rod or the second guide rod can be set to a metal material, which can increase the strength and rigidity of the first guide rail or the second guide rail. For example, when the material of the first guide rod or the second guide rod is metal and the adapter, the anti-shake bracket or the base is plastic, the metal first guide rod or the second guide rod can be used as an embedded part and directly molded into a structure with the adapter, the anti-shake bracket or the base through insert injection molding.

[0044] In a possible implementation, the second driving component includes a second magnetic element and a second coil, wherein the second magnetic element is disposed on the base frame, the second coil is disposed on the anti-shake bracket, and the second magnetic element and the second coil are disposed opposite to each other.

[0045] When the second coil is energized, the second magnetic element is driven to move, thereby driving the base to move.

[0046] By setting a second driving component to drive the base, and by setting the second driving component to a structure including a second magnetic element and a second coil, the second magnetic element can generate a driving force when the second coil is energized, and the moving direction and moving distance of the base can be adjusted by adjusting the current in the second coil. The structures of the magnetic element and the coil are relatively simple and easy to set up. Therefore, the structure of the camera motor can be simplified, thereby reducing costs.

[0047] A second aspect of an embodiment of the present application provides a camera module, comprising a camera motor as described in any one of the first aspects above.

[0048] By setting the camera motor of the first aspect in the camera module, since the camera motor is integrally formed with a guide rail along the optical axis direction of the lens on one of the carrier and the base, and a guide groove cooperating with the guide rail is provided on the other of the carrier and the base, the guide rail and the guide groove can be integrally formed on the carrier or the base, respectively, and in particular, the guide rail is integrally formed on the carrier or the base, so that the parts of the camera motor can be reduced and the cost can be reduced while ensuring that the carrier can move relative to the base along the optical axis direction of the lens. Compared with setting the guide rail separately, this can simplify the camera motor and simplify the assembly process, thereby solving the problem of complex drive motor structure and cumbersome assembly process in the related art. In addition, by integrally forming the guide rail on the carrier or the base, the problem of the guide rail loosening and falling off can also be solved. Thus, the structure of the camera module is simplified, the cost is reduced, and the service life of the camera module is increased.

[0049] A third aspect of an embodiment of the present application provides an electronic device, comprising the camera motor described in any one of the first aspects above, or comprising the camera module described in the second aspect above.

[0050] The electronic device includes a camera module or a camera motor, wherein in the camera module and the camera motor structure, since the guide rail and the guide groove are respectively integrally formed on the carrier or the base, the structure of the camera motor and the camera module can be simplified, the complexity of assembly can be reduced, and the guide rail can be prevented from falling off the camera motor, which helps to improve the performance of the electronic device and reduce the cost of the electronic device.

[0095] 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.

[0096] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and other forms thereof, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open, inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example" or "some examples" and the like are intended to indicate that specific features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics described may be included in any one or more embodiments or examples in any appropriate manner.

[0097] In addition, in the present application, directional terms such as "front" and "rear" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the changes in the orientation of the components in the drawings.

[0098] In the embodiments of the present application, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0099] 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, the slide-type autofocus camera (auto focus, AF) provides a better shooting experience due to its excellent anti-tilt ability. Taking mobile phones as an example, existing mobile phone autofocus telephoto camera modules usually adopt a periscope motor architecture design. Compared with shrapnel and ball motors, the slide-type motor can be adsorbed on the guide rail and move smoothly, the focusing process is more stable, and the shooting experience is better.

[0100] Among them, the driving motor is the carrier for the camera module to achieve focus and anti-shake. Driven by the motor thrust, the lens moves to the specified position with the movement of the motor carrier, thereby achieving the focus and anti-shake functions. In the existing camera module, the motor structure usually includes a base, a carrier, a guide rod, a magnet and a driving coil, wherein the coil is fixed on the base, the magnet is set on the carrier, and the magnet and the coil are arranged relative to each other, the guide rod is set between the carrier and the base, and the guide rod is fixed on the base by glue, and the carrier and the guide rod are connected by sliding. When in use, when a certain amount of current is passed into the driving coil, a corresponding force will be generated between the driving coil and the magnet, and the driving carrier will move along the guide rod to achieve the function of automatic focusing. Moreover, the guide rods in the related art are mostly metal guide rods, and the surface roughness and straightness of the metal guide rod material need to be controlled. The assembly of multiple guide rods needs to maintain a certain parallelism and height difference between different guide rods, which has high requirements on motor materials and assembly processes. In addition, when the independent guide rods and components are assembled and fixed, they need to be glued or laser welded, which is complicated and has the risk of loosening the guide rods after reliability testing. In addition, the hardness of the metal guide rod is much higher than that of the plastic carrier sliding on it, and it is easy to cause concave deformation on the contact surface of the plastic carrier during a drop test, affecting the drive control and optical performance.

[0101] Based on the above technical problems, the embodiments of the present application provide a camera motor, a camera module and an electronic device. The camera motor can eliminate the guide rod, which is a separate component, by integrally forming the guide rail on a carrier or a base, thereby eliminating the problem of the guide rail falling off, and simplifying the assembly process of the camera motor, thereby simplifying the assembly process of the camera module, which helps to improve the production efficiency of the camera module.

[0102] The following is a detailed description of a camera motor, a camera module and an electronic device provided in an embodiment of the present application in conjunction with the accompanying drawings.

[0103] For example, in the embodiment of the present application, the optical axis direction of the lens of the camera module is taken as the z direction, the first direction is taken as the x direction, and the second direction is taken as the y direction.

[0104] Figure 1 A schematic diagram of the structure of a camera motor provided in an embodiment of the present application. Figure 1 The middle is a vertical AF motor structure.

[0105] See also Figure 1 As shown, a camera motor 100 according to an embodiment of the present application is used to drive the lens of a camera module to move, and the camera motor 100 may include a housing 10, a base frame 11 and a carrier 13 disposed in the housing 10. Exemplarily, the carrier 13 may be movably disposed on the base frame 11, and the carrier 13 is used to carry the lens of the camera module.

[0106] Figure 2 A schematic diagram of the exploded structure of a camera motor provided in an embodiment of the present application.

[0107] See also Figure 2 As shown, the camera motor 100 may also include a first driving component 12, a portion of the structure of the first driving component 12 is arranged on the base frame 11, and another portion of the structure of the first driving component 12 is arranged on the carrier 13. The first driving component 12 can drive the carrier 13 to move relative to the base frame 11, thereby causing the lens of the camera module to move relative to the base frame 11 along the optical axis of the lens.

[0108] Exemplarily, the first driving component 12 may include a first magnetic element 121 and a first coil 122; wherein, the first coil 122 is arranged on the base frame 11, the first magnetic element 121 is arranged on the carrier 13, and the first magnetic element 121 and the first coil 122 are arranged relative to each other; when the first coil 122 is energized, the first magnetic element 121 is driven to move, thereby driving the carrier 13 to move.

[0109] Exemplarily, a receiving groove for receiving the first coil 122 is provided on the base frame 11, and a mounting cavity for mounting the first magnetic element 121 is provided on the carrier 13. In the embodiment of the present application, the specific structure of the receiving groove and the mounting cavity is not further described.

[0110] By configuring the first driving component 12 to include a first magnetic element 121 and a first coil 122, the first magnetic element 121 can generate a driving force when the first coil 122 is energized, and the moving direction and distance of the carrier 13 can be adjusted by adjusting the current in the first coil 122. The structures of the magnetic element and the coil are relatively simple and easy to configure. Therefore, the structure of the camera motor 100 can be simplified, thereby reducing costs.

[0111] It should be noted that the camera motor 100 may also include a power supply device (not shown in the figure), which can be connected to the first coil 122 to supply power to the first coil 122.

[0113] See also Figure 3 As shown, a guide rail 14 along the optical axis of the lens is integrally formed on the carrier 13. Figure 4As shown, a guide groove 15 is provided on the base frame 11 to cooperate with the guide rail 14. Exemplarily, the guide rail 14 extends along the z direction, and the extension direction of the guide groove 15 is the same as that of the guide rail 14. In the z direction, the guide rail 14 and the guide groove 15 are movably connected, so that the guide rail 14 can move in the guide groove 15, thereby driving the lens of the camera module to move along the z direction.

[0114] Figure 5 A schematic diagram of the cross-sectional structure of a camera motor provided in an embodiment of the present application.

[0115] For the convenience of description, in the embodiment of the present application, the two guide rails 14 are respectively used as the first guide rail 141 and the second guide rail 142. Correspondingly, the two guide grooves 15 are respectively used as the first guide groove 151 and the second guide groove 152. The first guide rail 141 is connected with the first guide groove 151, and the second guide rail 142 is connected with the second guide groove 152.

[0116] like Figure 5 As shown, each guide groove 15 is provided with a guide rail 14, and in the extension direction (z direction) of the guide rail 14, the guide rail 14 and the guide groove 15 are movably connected. Figure 4 and Figure 5 As shown, the first guide groove 151 includes a first side wall 1511 and a second side wall 1512 that are oppositely arranged, and a connecting wall 1513 located between the first side wall 1511 and the second side wall 1512, wherein both sides of the first guide rail 141 abut against the first side wall 1511 and the second side wall 1512 respectively, and there is a certain gap between the first guide rail 141 and the connecting wall 1513. The second guide groove 152 includes a third side wall 1521 and a fourth side wall 1522 that are connected to each other, wherein the second guide rail 142 abuts against the third side wall 1521, and there is a certain gap between the second guide rail 142 and the fourth side wall 1522.

[0117] It should be noted that, due to production tolerances, the sizes of the first guide rail 141 and the second guide rail 142 may deviate from the ideal values. Therefore, in order to ensure that the guide rail 14 and the guide groove 15 can be assembled, in the embodiment of the present application, a certain free space is reserved between the first guide rail 141 and the first guide groove 151 and between the second guide rail 142 and the second guide groove 152, that is, the gap between the first guide rail 141 and the connecting wall 1513 of the first guide groove 151 and the gap between the second guide rail 142 and the second guide groove 152. In this way, when the sizes of the first guide rail 141 and the second guide rail 142 are larger than the ideal sizes, they can also be assembled with the first guide groove 151 and the second guide groove 152.

[0118] In addition, by abutting the first guide rail 141 against the first side wall 1511 and the second side wall 1512 of the first guide groove 151, respectively, the freedom of the first guide rail 141 in two directions in the vertical plane of the z direction can be limited, that is, the freedom of the carrier 13 in two directions in the vertical plane of the z direction is limited. By abutting the second guide rail 142 and the third side wall 1521 of the second guide groove 152, the freedom of the second guide rail 142 in one direction in the vertical plane of the z direction can be limited. In this way, by changing the structure of the first guide groove 151 and the second guide groove 152, the freedom of the carrier 13 in different directions can be changed, so that the carrier 13 can only move along the z direction.

[0119] It should be noted that, in the embodiment of the present application, the two directions limited by the first side wall 1511 and the second side wall 1512 are the x direction and the y direction respectively, and the direction limited by the third side wall 1521 is located between the x direction and the y direction, and forms an angle of 45° with both the x direction and the y direction. Of course, in other embodiments, the directions limited by the first side wall 1511, the second side wall 1512, and the third side wall 1521 can also be other directions. In the embodiment of the present application, the directions limited by the first side wall 1511, the second side wall 1512, and the third side wall 1521 are not limited.

[0120] In other embodiments, Figure 2 As shown, a magnetic conductive sheet may also be provided on the outer side of the first driving component 12 provided on the base frame 11. For example, a first magnetic conductive sheet 111 may be provided on the outer side of the first driving component 12 close to the first guide rail 141, and a second magnetic conductive sheet 112 may be provided on the outer side of the first driving component 12 close to the second guide rail 142, wherein the size of the first magnetic conductive sheet 111 is larger than the second magnetic conductive sheet 112, so that the magnetic attraction force generated at the first driving component 12 corresponding to the first magnetic conductive sheet 111 may be larger than the magnetic attraction force generated at the first driving component 12 corresponding to the second magnetic conductive sheet 112, that is, a biased magnetic attraction force may be generated between the two first driving components 12, so that the carrier 13 may be closer to one side of the base frame 11, so that the stability of the fit between the guide rail 14 and the guide groove 15 may be enhanced.

[0121] It should be noted that, in the embodiment of the present application, there is no further limitation on the specific size of the first magnetic conductive sheet 111 and the second magnetic conductive sheet 112. In addition, in some embodiments, the magnetic conductive sheet may not be provided, and may be provided specifically according to the installation position of the guide rail 14.

[0122] The camera motor 100 in the embodiment of the present application is formed with a guide rail 14 along the optical axis of the lens on one of the carrier 13 and the base 11, and a guide groove 15 cooperating with the guide rail 14 is provided on the other of the carrier 13 and the base 11. In this way, the guide rail 14 and the guide groove 15 can be formed integrally on the carrier 13 or the base 11, respectively. In particular, the guide rail 14 is formed integrally on the carrier 13 or the base 11. In this way, the parts of the camera motor 100 can be reduced and the cost can be reduced under the premise of ensuring that the carrier 13 can move relative to the base 11 along the optical axis of the lens. Compared with setting a separate guide rod and then connecting the guide rod to the carrier by glue bonding or laser welding, the technical solution in the embodiment of the present application can simplify the camera motor 100 and simplify the assembly process. This solves the problem of complex drive motor structure and cumbersome assembly process in the related art. In addition, by forming the guide rail 14 integrally on the carrier 13 or the base 11, the problem of loosening and falling off of the guide rail 14 can also be solved.

[0123] In some embodiments, a housing cavity for accommodating a lens is formed in the middle of the carrier 13, and a plurality of guide rails 14 or guide grooves 15 are arranged at intervals outside the housing cavity. An assembly space for installing the carrier 13 is formed in the middle of the base frame 11, and the carrier 13 is installed in the assembly space of the base frame 11, so that the base frame 11 has a certain supporting effect on the carrier 13.

[0124] By providing an accommodating cavity on the carrier 13, a mounting position is provided for the lens of the camera module so that the lens can be fixed on the carrier 13. In addition, by providing the accommodating cavity, the lens can be hidden in the carrier 13, so that the carrier 13 can protect the lens and thus improve the service life of the lens.

[0125] By providing multiple guide rails 14 or guide grooves 15, compared with providing only one guide rail 14 or guide groove 15, multiple positions of the carrier 13 can be supported, and the pressure on the individual guide rails 14 and guide grooves 15 can be reduced, thereby preventing the guide rail 14 from being broken due to excessive local force, thereby extending the service life of the guide rail 14 and thus extending the service life of the camera motor 100.

[0126] It should be noted that the number of guide rails 14 and guide grooves 15 is the same. For example, the number of guide rails 14 and guide grooves 15 can be two, three, four or more. In the embodiment of the present application, there is no limit on the number of guide rails 14 and guide grooves 15.

[0127] The following description will be made by taking an example that the number of the guide rails 14 and the number of the guide grooves 15 are both two.

[0128] In some embodiments, the guide rail 14 can be disposed on the carrier 13, and the guide groove 15 can be disposed on the base frame 11, for example, see Figure 3 As shown, two guide rails 14 are arranged at intervals outside the accommodating cavity of the carrier 13, see Figure 5 As shown, two guide grooves 15 are arranged on the base frame 11 at intervals and are located outside the accommodating cavity.

[0129] By providing two guide rails 14 and guide grooves 15, the structure of the camera motor 100 can be simplified, the cost can be reduced, and the force on the carrier 13 can be balanced. The carrier 13 can be effectively prevented from being offset when moving along the optical axis of the lens, ensuring that the carrier 13 can drive the lens to move only along the optical axis of the lens.

[0130] In the embodiment of the present application, the overall structure of the camera motor 100 is approximately a rectangular parallelepiped structure. The projection of the base frame 11 in the z direction is approximately a quadrilateral having four corners.

[0131] like Figure 2 and Figure 5 As shown, the guide rail 14 or the guide groove 15 is arranged at the diagonal position of the base frame 11, and the line between the two guide rails 14 passes through the optical axis of the lens.

[0132] It should be noted that the diagonals here refer to two opposite corners of the base frame 11 , that is, the line connecting the two guide rails 14 or guide grooves 15 is close to the diagonal line of the base frame 11 .

[0133] By arranging two guide rails 14 and guide grooves 15 at diagonal positions of the base frame 11, and with the line between the two guide rails 14 passing through the optical axis of the lens, the torque causing the carrier 13 to move when it is subjected to force can be reduced, and the carrier 13 can be effectively prevented from tilting when moving along the optical axis of the lens.

[0134] In the embodiment of the present application, two first drive assemblies 12 are provided between the two guide rails 14. Figure 2 and Figure 5 As shown, a first driving assembly 12 is provided on one side of each guide rail 14 , and two first driving assemblies 12 are respectively located on two adjacent side surfaces of the base frame 11 .

[0135] In addition, since the two guide rails 14 are arranged along the diagonal of the base frame 11, the guide rails 14 are arranged relatively dispersed. When a position of the carrier 13 is subjected to force, other positions will generate a large torque, which is easy to cause the optical axis of the lens to shift. By arranging two first driving assemblies 12 between two adjacent guide rails 14, the driving force can be increased and the driving force can be dispersed in different areas. Compared with arranging the first driving assembly at one position, this can reduce the torque of the carrier 13 when being driven, and further prevent the carrier 13 from shifting when moving along the optical axis direction of the lens.

[0136] It should be noted that the embodiment of the present application does not limit the location of the guide rail 14 and the guide groove 15. For example, in the embodiment of the present application, the guide rail 14 is arranged on the carrier 13, and the guide groove 15 is arranged on the base frame 11. In other embodiments, the guide groove 15 can also be arranged on the carrier 13, and the guide rail 14 can be arranged on the base frame 11. In other words, the guide rail 14 along the optical axis direction of the lens can be integrally formed on one of the carrier 13 and the base frame 11, and the guide groove 15 cooperating with the guide rail 14 can be opened on the other of the carrier 13 and the base frame 11.

[0137] In addition, the structures of the guide rail 14 and the guide groove 15 may also be other structures. In the embodiment of the present application, the structures of the guide rail 14 and the guide groove 15 are not limited.

[0138] Figure 6 A schematic structural diagram of a carrier body of a camera motor provided in an embodiment of the present application. Figure 7 A schematic structural diagram of a camera motor base frame provided in an embodiment of the present application.

[0139] like Figure 7 As shown, the base frame 11 is integrally formed with a guide rail 14 along the optical axis of the lens, see Figure 6 As shown, a guide groove 15 is provided on the carrier 13 to cooperate with the guide rail 14. Exemplarily, the guide rail 14 extends along the z direction, and the extension direction of the guide groove 15 is the same as that of the guide rail 14. In the z direction, the guide rail 14 and the guide groove 15 are movably connected, so that the guide rail 14 can move in the guide groove 15, thereby driving the lens of the camera module to move along the z direction.

[0140] like Figure 6 As shown, two guide grooves 15 are arranged at intervals on the outside of the accommodating cavity, see Figure 7 As shown, two guide rails 14 are arranged on the base frame 11 at intervals and are located outside the accommodating cavity. Figure 6 and Figure 7 In the embodiment, except for the arrangement positions of the guide rail 14 and the guide groove 15, and the structure of the guide groove 15, the other structures are the same as Figure 2-Figure 5The structure is the same as Figure 6 and Figure 7 For structures other than the guide rail 14 and the guide groove 15, see Figure 2 The description of the embodiments in the present invention will not be repeated here.

[0141] The following is a Figure 6 The guide groove 15 in the guide groove 15 is described in detail. In a possible implementation, a limiting portion 16 is provided on one of the guide rail 14 and the guide groove 15, and the other of the guide rail 14 and the guide groove 15 abuts against the limiting portion 16. Among them, three limiting portions 16 are provided between the multiple guide rails 14 and the multiple guide grooves 15. At least one limiting portion 16 is provided between each guide groove 15 and the guide rail 14 located in the guide groove 15. The three limiting portions 16 form a stable plane. In this way, the optical axis can be prevented from being offset during the movement of the lens driven by the carrier 13.

[0142] By providing the limiter 16, the freedom of the guide rail 14 when moving in the guide groove 15 can be limited, so that the carrier 13 can move in a stable plane along the extension direction of the guide rail 14, and the shaking of the lens on the carrier 13 can be avoided, ensuring that the optical axis of the lens is always on the same straight line, preventing the lens from shaking, and ensuring the shooting quality. In addition, the simple structure of the limiter 16 can simplify the structure of the camera motor 100 and reduce the cost.

[0143] In the extension direction (z direction) of the guide rail 14, a first limit portion 161 and a second limit portion 162 are provided between the first guide rail 141 and the first guide groove 151. The first limit portion 161 and the second limit portion 162 are spaced apart along the extension direction of the first guide rail 141, and the first guide rail 141 and the first guide groove 151 are abutted against each other via the first limit portion 161 and the second limit portion 162.

[0144] For example, Figure 6 As shown, the first limiting portion 161 and the second limiting portion 162 are respectively arranged at the two ends of the first guide groove 151 along the z direction. The third limiting portion 163 is arranged near the middle of the second guide groove 152 along the z direction. In this way, the mass distribution of the first guide groove 151 and the second guide groove 152 can be uniform, and deformation or wear caused by excessive local pressure on the guide rail 14 can be prevented. In the extension direction of the guide rail 14 (z direction), a third limiting portion 163 is provided between the second guide rail 142 and the second guide groove 152, and the second guide rail 142 and the second guide groove 152 are abutted by the third limiting portion 163. Among them, the first limiting portion 161, the second limiting portion 162 and the third limiting portion 163 form a stable plane ( Figure 6 ).

[0145] By setting three different limiting parts 16 between the guide rail 14 and the guide groove 15, the three different limiting parts 16 can form a stable plane, thereby ensuring that the carrier 13 can move smoothly along the extension direction of the guide rail 14 within a plane, avoiding the shaking of the lens located on the carrier 13, ensuring that the optical axis of the lens is always in the same straight line, preventing the lens from shaking, and ensuring the shooting quality.

[0146] In a possible implementation, the guide rail 14 is an integrated structure. Exemplarily, the guide rail 14 is a cylindrical structure. The limiting portion 16 is disposed in the guide groove 15 , and the limiting portion 16 is a protruding structure protruding outward from the inner wall of the guide groove 15 .

[0147] For example, Figure 6 As shown, the first guide groove 151 and the second guide groove 152 are located on the carrier 13, and the first guide rail 141 and the second guide rail 142 are located on the base frame 11. A first limiting portion 161 and a second limiting portion 162 are provided on the first guide groove 151, and the first limiting portion 161 and the second limiting portion 162 are two protruding structures protruding outward from the first side wall 1511 and the second side wall 1512 respectively. The third limiting portion 163 of the second guide groove 152 is a protruding structure protruding outward from the third side wall 1521, and the third limiting portion 163 on the second guide groove 152 is located near the middle of the second guide groove 152.

[0148] like Figure 8 As shown, the first guide rail 141 and the first guide groove 151 may abut against each other at the first limiting portion 161 and the second limiting portion 162 , and the second guide rail 142 and the second guide groove 152 may abut against each other at the third limiting portion 163 .

[0149] By setting the limiting portion 16 and setting the limiting portion 16 as a protruding structure, the contact area between the guide rail 14 and the guide groove 15 can be reduced, thereby reducing the friction between the guide rail 14 and the guide groove 15, so as to start the carrier 13, and also reduce the wear between the guide rail 14 and the guide groove 15.

[0150] Of course, in other embodiments, such as Fig. 9 As shown, the first guide groove 151 with the first limiting portion 161 and the second limiting portion 162, and the second guide groove 152 with the third limiting portion 163 can be arranged on the base frame 11, as shown in FIG. Fig.10 As shown, the first guide rail 141 and the second guide rail 142 are arranged on the carrier 13. Fig. 9 , Fig.10 The embodiments shown in Figure 6 , Figure 7 The embodiment shown in FIG. 1 is different only in the arrangement position of the guide rail 14 and the guide groove 15, and the other structures are the same. Fig. 9 and Fig.10 The structure of the guide groove 15 in the embodiment can be seen in Figure 6 The description of the guide groove 15 in the embodiment of the present application will not be repeated again.

[0151] It should be noted that, in order to ensure that the carrier 13 moves in the first guide groove 151 and the second guide groove 152 along the z direction, in the embodiment in which the guide rail 14 is arranged on the carrier 13, the length of the guide groove 15 along the z direction needs to be set greater than the length of the guide rail 14 in the z direction. When the guide rail 14 is arranged on the base frame 11, the length of the guide rail 14 along the z direction needs to be set greater than the length of the guide groove 15 in the z direction. In the embodiment of the present application, the specific lengths of the guide rail 14 and the guide groove 15 are not further limited.

[0152] Of course, in another embodiment, the limiting portion 16 may be set as other structures, for example, the guide rail 14 may be set as the limiting portion 16. Fig.11 As shown, a guide rail 14 is provided on the carrier 13 . In the embodiment of the present application, the first guide rail 141 is a split structure, and the first guide rail 141 and the second guide rail 142 are both limiting portions 16 .

[0153] Exemplarily, the first guide rail 141 includes two sub-guide rails 1411 spaced apart along the z direction, and each sub-guide rail 1411 is a cylindrical structure extending along the z direction. The two sub-guide rails 1411 are respectively located at the two ends of the carrier 13 along the z direction, the second guide rail 142 is an integrated structure, and the second guide rail 142 is arranged at a position close to the middle of the carrier 13 along the z direction. The dimension of the second guide rail 142 along the z direction is much smaller than the length of the second guide groove 152 along the z direction. The two sub-guide rails 1411 of the first guide rail 141 are respectively the first limiting portion 161 and the second limiting portion 162, and the second guide rail 142 is the third limiting portion 163. In this case, the base frame 11 can be Figure 4 The structure shown in .

[0154] In the embodiment of the present application, by setting the first guide rail 141 as a split structure and setting the size of the second guide rail 142 to be smaller, the first guide rail 141 and the second guide rail 142 can be directly used as the limiting part 16, thereby achieving three-point contact between the guide rail 14 and the guide groove 15, thereby forming a stable plane to ensure that the carrier 13 can move within a plane along the extension direction of the guide rail 14, thereby avoiding the shaking of the lens located on the carrier 13, ensuring that the optical axis of the lens is always in the same straight line, preventing the lens from shaking, and ensuring the shooting quality.

[0155] It should be noted that in the embodiments of the present application, the shape of the guide rail 14 is a cylindrical structure. Of course, in other embodiments, the shape of the guide rail 14 can also be designed as other structures, and the structural features of the guide rail include cylindrical surfaces and special shape surfaces, continuous guide rails or segmented guide rail designs. For example, a prismatic structure, etc. In the embodiments of the present application, the shape of the guide rail 14 is not further limited.

[0156] In addition, it can be understood that, for the embodiment in which the guide rail 14 can be set as the limiting portion 16, the guide rail 14 can also be set on the base frame 11, for example, Fig.11 The guide rail 14 shown in Figure 4 The positions of the guide grooves 15 are interchanged, and other structures remain unchanged. The embodiment in which the positions of the guide rails 14 and the guide grooves 15 are interchanged will not be further described.

[0157] In a possible implementation, the guide rail 14 can be formed on the carrier 13 or the base frame 11 by one-time injection molding. Exemplarily, when the guide rail 14 and the carrier 13 or the base frame 11 are made of the same material, the guide rail 14 and the carrier 13 or the base frame 11 can be directly formed into one component by one-piece injection molding. By forming the guide rail 14 on the carrier 13 or the base frame 11 by one-time injection molding, the processing technology of the carrier 13 or the base frame 11 can be simplified, thereby reducing costs.

[0158] In a possible implementation, the guide rail 14 may be formed on the carrier 13 or the base frame 11 by secondary injection molding.

[0159] The guide rail 14 is formed on the carrier 13 or the base frame 11 by secondary injection molding. For example, the carrier 13, the base frame 11 and the guide rail 14 can be formed separately first, and then the guide rail 14 and the carrier 13 or the base frame 11 are formed by secondary injection molding. In this case, the material of the guide rail 14 can be polyetheretherketone (PEEK), polyphenylene sulfide (PPS plastic), liquid crystal polymer (LCP) and other materials with relatively high hardness and relatively low friction coefficient, and the carrier 13 and the base frame 11 can be other insulating materials.

[0160] In a possible implementation, the guide rail 14 may be insert-molded on the carrier 13 or the base frame 11 .

[0161] By stamping the guide rail 14 on the carrier 13 or the base frame 11, the guide rail 14 can be set to a metal material, which can increase the strength of the guide rail 14. For example, when the guide rail 14 is made of metal and the carrier 13 and the base frame 11 are made of plastic, the metal guide rail 14 can be used as an embedded part and directly formed into a structure with the carrier 13 or the base frame 11 through insert injection molding.

[0162] It should be noted that the material of the carrier 13 and the base frame 11 can be an insulating material, such as plastic. The material of the guide rail 14 can be an insulating material, such as plastic, or metal. In the embodiment of the present application, the material of the guide rail 14, the carrier 13 and the base frame 11 is not limited.

[0163] In addition, when in use, lubricating oil / grease can be pre-coated on the friction surface of the guide rail to reduce the dynamic friction coefficient, or a wear-resistant coating can be plated on the surface of the guide rail to improve wear resistance.

[0164] The camera motor in the embodiment of the present application forms the guide rail structure on the plastic part through one-piece injection molding, replacing the sliding shaft motor assembly process of the metal guide rod installed later in the related art, which can greatly reduce the number of camera motor components and assembly procedures, thereby reducing the cost of the camera motor. In addition, the structure and material selection of the guide rail are diversified, and reliability problems such as loosening of the metal guide rod are solved from the source. Moreover, the guide rail structure of the camera motor in the present application can be injection molded together with the plastic part (carrier or base) by means of one-time injection molding of the same plastic, two-time injection molding of different plastics, or metal guide rails as embedded parts. The molding process is diversified, and the structure of the guide rail is diversified to adapt to different scenes.

[0165] The above are all embodiments in which the two guide rails 14 are arranged at the diagonal positions of the base frame 11. Of course, in other embodiments, the two guide rails 14 may also be arranged on one side of the base frame 11. The following is a detailed description with reference to the accompanying drawings.

[0167] like Fig.12As shown, a camera motor 100 according to an embodiment of the present application is used to drive the movement of the lens of a camera module. The camera motor 100 may include a shell 10, a base 11, a carrier 13 and a first driving component 12, wherein the base 11, the carrier 13 and the first driving component 12 are all arranged in the shell 10, the carrier 13 is arranged in the base 11, and the first driving component 12 is arranged between the base 11 and the carrier 13, wherein the first driving component 12 is used to drive the carrier 13 to move relative to the base 11 along the optical axis of the lens.

[0168] Exemplarily, the first driving component 12 may include a first magnetic element 121 and a first coil 122; wherein, the first coil 122 is arranged on the base frame 11, the first magnetic element 121 is arranged on the carrier 13, and the first magnetic element 121 and the first coil 122 are arranged relative to each other; when the first coil 122 is energized, the first magnetic element 121 is driven to move, thereby driving the carrier 13 to move.

[0169] Exemplarily, a receiving groove for receiving the first coil 122 is provided on the base frame 11, and a mounting cavity for mounting the first magnetic element 121 is provided on the carrier 13. In the embodiment of the present application, the specific structure of the receiving groove and the mounting cavity is not further described.

[0170] It should be noted that the camera motor 100 may also include a power supply device (not shown in the figure), which can be connected to the first coil 122 to supply power to the first coil 122.

[0172] In the embodiments of the present application, Fig.13 As shown, a guide rail 14 along the optical axis direction (z direction) of the lens is integrally formed on the carrier 13. Fig.14 As shown, a guide groove 15 is provided on the base frame 11 to cooperate with the guide rail 14. Exemplarily, the guide rail 14 extends along the z direction, and the extension direction of the guide groove 15 is the same as that of the guide rail 14. In the z direction, the guide rail 14 and the guide groove 15 are movably connected, so that the guide rail 14 can move in the guide groove 15, thereby driving the lens of the camera module to move along the z direction.

[0173] Exemplarily, the overall structure of the camera motor 100 is a rectangular parallelepiped structure, or a structure that is similar to a rectangular parallelepiped. The projection of the base frame 11 in the z direction is similar to a quadrilateral with four corners. The guide rail 14 or the guide groove 15 is arranged at the corner of the base frame 11. In the embodiment of the present application, the corner refers to a position close to the corner, not a true geometric corner.

[0174] Exemplarily, the number of guide rails 14 and guide grooves 15 are both two, wherein the guide rail 14 includes a first guide rail 141 and a second guide rail 142, and the guide groove 15 includes a first guide groove 151 and a second guide groove 152, the first guide rail 141 is matched and connected with the first guide groove 151, and the second guide rail 142 is matched and connected with the second guide groove 152. The first guide groove 151 and the second guide groove 152 are respectively arranged at two corners located on the same surface of the base frame 11 or near the corners, that is, the first guide groove 151 and the second guide groove 152 are located on the same surface of the base frame 11.

[0175] In the embodiment of the present application, two first driving components 12 are respectively arranged on two side walls extending along the z direction of the base frame 11, and are located outside the first guide rail 141 and the second guide rail 142. By arranging a first driving component 12 outside the first guide rail 141 and the second guide rail 142, the driving force can be increased, and the driving force can be dispersed in different areas. Compared with arranging the driving component in one position, the torque of the carrier 13 when being driven can be reduced, thereby preventing the carrier 13 from being offset when moving along the optical axis direction of the lens.

[0176] Of course, in other embodiments, the first drive assembly 12 may also be disposed at other positions. For example, a first drive assembly 12 (not shown in the figure) may be disposed on the plane where the first guide rail 141 and the second guide rail 142 are located. This can generate a balanced driving force on both sides of the carrier 13, prevent the carrier 13 from shifting when moving along the optical axis of the lens, simplify the structure of the camera motor 100, simplify the assembly process, and thus reduce costs.

[0177] Similar to the above-mentioned embodiment, in the extension direction (z direction) of the guide rail 14, a first limiting portion 161 and a second limiting portion 162 are provided between the first guide rail 141 and the first guide groove 151, and the first limiting portion 161 and the second limiting portion 162 are spaced apart along the extension direction of the first guide rail 141, and the first guide rail 141 and the first guide groove 151 are abutted against each other via the first limiting portion 161 and the second limiting portion 162.

[0178] For example, Fig.13As shown, the first guide rail 141 includes two sub-guide rails 1411 spaced apart along the z direction, and each sub-guide rail 1411 is a cylindrical structure extending along the z direction. The two sub-guide rails 1411 are respectively located at the two ends of the carrier 13 along the z direction, the second guide rail 142 is an integrated structure, and the second guide rail 142 is arranged at a position close to the middle of the carrier 13 along the z direction. The dimension of the second guide rail 142 along the z direction is much smaller than the length of the second guide groove 152 along the z direction. The two sub-guide rails 1411 of the first guide rail 141 are the first limiting portion 161 and the second limiting portion 162, respectively, and the second guide rail 142 is the third limiting portion 163.

[0179] By setting three different limiting parts 16 between the guide rail 14 and the guide groove 15, the three different limiting parts 16 can form a stable plane ( Fig.13 In this way, it is ensured that the carrier 13 can move in a plane along the extension direction of the guide rail 14, and the shaking of the lens on the carrier 13 can be avoided, and the optical axis of the lens is always on the same straight line, so as to prevent the lens from shaking and ensure the shooting quality.

[0180] For example, Fig.14 As shown, the first guide groove 151 and the second guide groove 152 both extend along the z direction, and the first guide groove 151 includes a first side wall 1511 and a second side wall 1512 that are oppositely arranged, and a connecting wall 1513 located between the first side wall 1511 and the second side wall 1512. Fig.15 As shown, the two sides of the first guide rail 141 are respectively in contact with the first side wall 1511 and the second side wall 1512, and there may be a certain gap between the first guide rail 141 and the connecting wall 1513, or they may be in contact and connected. The second guide groove 152 includes a third side wall 1521 and a fourth side wall 1522 connected to each other, wherein the second guide rail 142 is in contact with the third side wall 1521, and there is a certain gap between the second guide rail 142 and the fourth side wall 1522.

[0181] It should be noted that due to production tolerances, the sizes of the first guide rail 141 and the second guide rail 142 may deviate from the ideal values. Therefore, in order to ensure that the guide rail 14 and the guide groove 15 can be assembled, in the embodiment of the present application, a certain free space is reserved between the first guide rail 141 and the first guide groove 151 and between the second guide rail 142 and the second guide groove 152, that is, the gap between the first guide rail 141 and the connecting wall 1513 of the first guide groove 151 and the gap between the second guide rail 142 and the second guide groove 152. In this way, when the sizes of the first guide rail 141 and the second guide rail 142 are larger than the ideal sizes, they can also be assembled with the first guide groove 151 and the second guide groove 152.

[0182] By providing three limiting portions 16, the three positions can always be kept tightly connected during the movement of the guide rail 14 along the guide groove 15. In the embodiment of the present application, the limiting portion 16 is provided on the guide rail 14. Of course, in other embodiments, the limiting portion 16 can also be provided in the guide groove 15, that is, the limiting portion 16 can be provided on one of the guide rail 14 and the guide groove 15.

[0183] In addition, in some other embodiments, the guide rail 14 and the guide groove 15 may also be in other shapes, and the positions of the guide rail 14 and the guide groove 15 may also be interchangeable. Fig.16 and Fig.17 As shown, Fig.16 and Fig.17 The structure shown in the embodiment is only the location and shape of the guide rail 14 and the guide groove 15. Fig.12 For other structures, please refer to the above Fig.12 Description of the embodiments in .

[0184] like Fig.17 As shown, the guide rail 14 is arranged on the base frame 11, as shown in FIG. Fig.16 As shown, the guide groove 15 is provided on the carrier 13. In addition, the guide rail 14 is an integrated cylindrical structure, the limit portion 16 is provided in the guide groove 15, and the limit portion 16 is a protruding structure protruding outward from the inner wall of the guide groove 15. By setting the limit portion 16 as a protruding structure, the structure of the limit portion 16 can be simplified, thereby simplifying the structure of the camera motor 100 and reducing the production cost.

[0185] For example, see Fig.16 As shown, the first guide groove 151 and the second guide groove 152 are both provided with a limiting portion 16. The first guide groove 151 is provided with a first limiting portion 161 and a second limiting portion 162, and the first limiting portion 161 and the second limiting portion 162 are two protrusion structures protruding outward from the first side wall 1511 and the second side wall 1512 respectively. The third limiting portion 163 of the second guide groove 152 is a protrusion structure protruding outward from the third side wall 1521, and the third limiting portion 163 on the second guide groove 152 is located near the middle of the second guide groove 152.

[0186] By setting the limiting portion 16 and setting the limiting portion 16 as a protruding structure, the contact area between the guide rail 14 and the guide groove 15 can be reduced, thereby reducing the friction between the guide rail 14 and the guide groove 15, so as to drive the carrier 13, and also reduce the wear between the guide rail 14 and the guide groove 15.

[0187] It should be noted that Fig.16 and Fig.17 The examples in Fig.12The difference between the embodiments in FIG. 1 and FIG. 2 is only in the structure and setting position of the guide rail 14 and the guide groove 15. For other structures of the camera motor 100, please refer to the embodiment of FIG. Fig.12 The description of the embodiments in the present invention will not be repeated here.

[0188] Of course, in another embodiment, the limiting portion 16 may not be provided. Fig.18 As shown, the first guide rail 141 and the second guide rail 142 can be set on the carrier 13, and the first guide rail 141 and the second guide rail 142 are both cylindrical structures, and the base frame 11 can be Fig.14 In this way, the guide rail 14 and the guide groove 15 can be flexibly connected without setting a stopper, and the structure of the carrier 13 and the base frame 11 can be simplified, thereby reducing the cost of the camera motor 100.

[0189] In addition, for Fig.16 and Fig.17 In the embodiment shown in , the setting positions of the guide rail 14 and the guide groove 15 can be interchanged. In the embodiment of the present application, the setting positions of the guide rail 14 and the guide groove 15 are not further described.

[0190] In some other embodiments, an optical image stabilization (OIS) system may be further provided between the carrier 13 and the base frame 11 .

[0192] In the embodiment of the present application, the anti-shake bracket 18, the adapter frame 17 and the second drive assembly 19 are arranged on the side of the base frame 11 away from the carrier 13.

[0194] It should be noted that the anti-shake bracket 18, the adapter frame 17 and the second drive component 19 together constitute an optical anti-shake system. By setting the anti-shake bracket 18, the adapter frame 17 and the second drive component 19, the optical axis offset can be automatically corrected when the camera shakes, so that handheld shooting will not produce blur, thereby improving the performance of the camera module.

[0200] In the embodiments of the present application, Fig. 20 As shown, the base frame 11 is integrally formed with a guide rail 14 along the optical axis of the lens. Fig.21 As shown, a guide groove 15 is provided on the carrier 13 to cooperate with the guide rail 14. Exemplarily, the guide rail 14 extends along the z direction, and the extension direction of the guide groove 15 is the same as that of the guide rail 14. In the z direction, the guide rail 14 and the guide groove 15 are movably connected, so that the guide rail 14 can move in the guide groove 15, thereby driving the lens of the camera module to move along the z direction.

[0201] Exemplarily, the overall structure of the camera motor 100 is a rectangular parallelepiped structure, or a structure that is similar to a rectangular parallelepiped. The projection of the base frame 11 in the z direction is similar to a quadrilateral with four corners. The guide rail 14 or the guide groove 15 is arranged at the corner of the base frame 11. In the embodiment of the present application, the corner refers to a position close to the corner, not a true geometric corner.

[0202] Exemplarily, the number of guide rails 14 and guide grooves 15 are both two, wherein the guide rail 14 includes a first guide rail 141 and a second guide rail 142, and the guide groove 15 includes a first guide groove 151 and a second guide groove 152, the first guide rail 141 is matched and connected with the first guide groove 151, and the second guide rail 142 is matched and connected with the second guide groove 152. The first guide groove 151 and the second guide groove 152 are respectively arranged at two corners located on the same surface of the base frame 11 or near the corners, that is, the first guide groove 151 and the second guide groove 152 are located on the same surface of the base frame 11.

[0203] In some embodiments, a first driving assembly 12 is disposed on the plane where the first guide rail 141 and the second guide rail 142 are located. By disposing the first driving assembly 12 between the two guide rails 14, a balanced driving force can be generated on both sides of the carrier 13, and the carrier 13 can be prevented from being offset when moving along the optical axis direction of the lens, and the structure of the camera motor 100 can be simplified, and the assembly process can be simplified, thereby reducing costs.

[0204] like Fig.21As shown, the first guide groove 151 is provided with a first limiting portion 161 and a second limiting portion 162, and the first limiting portion 161 and the second limiting portion 162 are two protrusion structures protruding outward from the first side wall 1511 and the second side wall 1512 respectively. The third limiting portion 163 of the second guide groove 152 is a protrusion structure protruding outward from the third side wall 1521.

[0205] Exemplarily, the first limit portion 161 and the second limit portion 162 are respectively disposed at two ends of the first guide groove 151 along the z direction. The third limit portion 163 is disposed near the middle of the second guide groove 152 along the z direction. In this way, the mass distribution of the first guide groove 151 and the second guide groove 152 can be uniform, and the guide rail 14 can be prevented from being bent or worn due to excessive local pressure.

[0206] By setting three different limiting portions 16 between the guide rail 14 and the guide groove 15, the three different limiting portions 16 can form a stable plane (see Fig.21 In this way, the carrier 13 can be moved in a plane along the extension direction of the guide rail 14, so that the three positions can always be tightly connected during the movement of the guide rail 14 along the guide groove 15. The shaking of the lens on the carrier 13 can be avoided, the optical axis of the lens is always on the same straight line, the lens shaking is prevented, and the shooting quality is guaranteed.

[0207] like Fig. 20 As shown, the guide rail 14 can be set as an integrated structure, and the guide rail 14 is a cylindrical structure. Of course, in some other embodiments, the setting positions of the guide rail 14 and the guide groove 15 can also be interchanged, for example, the guide rail 14 is set on the carrier 13, and the guide groove 15 is set on the base frame 11. Of course, the structures of the guide rail 14, the guide groove 15 and the limit portion 16 can also be other forms of structures.

[0208] like Fig. 22 and Fig.23As shown, in the embodiment of the present application, the guide rail 14 is integrally formed on the carrier 13, and the guide groove 15 is arranged on the base frame 11. Among them, the first guide groove 151 and the second guide groove 152 are both groove-shaped structures extending along the z-direction. The first guide rail 141 is a split structure, and the first guide rail 141 and the second guide rail 142 are both limiting parts 16. The first guide rail 141 includes two sub-guide rails 1411 spaced apart along the z-direction, and each sub-guide rail 1411 is a cylindrical structure extending along the z-direction. Among them, the two sub-guide rails 1411 are respectively located at the two ends of the carrier 13 along the z-direction, the second guide rail 142 is an integral structure, and the second guide rail 142 is arranged at a position close to the middle of the carrier 13 along the z-direction. Among them, the size of the second guide rail 142 along the z-direction is much smaller than the length of the second guide groove 152 along the z-direction. The two sub-guide rails 1411 of the first guide rail 141 are respectively the first limiting portion 161 and the second limiting portion 162 , and the second guide rail 142 is the third limiting portion 163 .

[0209] It should be noted that Fig. 22 and Fig.23 In the embodiment shown in FIG. 1 , except that the shape and arrangement position of the guide rail 14 and the guide groove 15 are the same as those of the embodiment shown in FIG. Fig.19 Different from the above, the other structures are the same as Fig.19 The same as in the embodiment, therefore, for 22 and Fig.23 For other structures of the embodiment shown in Fig.19 The description of the embodiments in the present invention will not be repeated here.

[0210] It should be noted that the setting positions of the guide rail 14 and the guide groove 15 are interchangeable. For example, the guide rail 14 can be set on the carrier 13 and the guide groove 15 can be set on the base frame 11, or the guide rail 14 can be set on the base frame 11 and the guide groove 15 can be set on the carrier 13. In the embodiment of the present application, the setting positions of the guide rail 14 and the guide groove 15 are not further limited.

[0211] The structures of the anti-shake bracket 18, the adapter bracket 17 and the second driving assembly 19 are described in detail below with reference to the accompanying drawings.

[0212] Fig.24 A schematic structural diagram of the side of an adapter frame of a camera motor facing a base frame provided in an embodiment of the present application. Fig.25 A schematic structural diagram of a side of a base frame of a camera motor facing an adapter frame provided in an embodiment of the present application.

[0213] In some embodiments, a first guide rod 21 extending along a first direction (x direction) is integrally formed on one of the adapter frame 17 and the base frame 11, and a first slide groove 22 corresponding to the first guide rod 21 is provided on the other of the adapter frame 17 and the base frame 11, a first guide rod 21 is provided in each first slide groove 22, and the first guide rod 21 and the first slide groove 22 are movably connected along the first direction (x direction). A second guide rod 23 extending along a second direction (x direction) is integrally formed on one of the adapter frame 17 and the anti-shake bracket 18, and a second slide groove 24 corresponding to the second guide rod 23 is provided on the other of the adapter frame 17 and the anti-shake bracket 18, a second guide rod 23 is provided in each second slide groove 24, and the second guide rod 23 and the second slide groove 24 are movably connected along the second direction (y direction).

[0214] For example, Fig.24 As shown, the adapter frame 17 is integrally formed with a first guide rod 21 extending along a first direction (x direction). Fig.25 As shown, the base frame 11 is provided with first sliding grooves 22 corresponding to the first guide rods 21 , each first sliding groove 22 is provided with a first guide rod 21 , and the first guide rod 21 and the first sliding groove 22 are movably connected along a first direction.

[0215] Exemplarily, the adapter frame 17 is an L-shaped structure, and the number of the first guide rods 21 and the first slide slots 22 are three, wherein the three first guide rods 21 are respectively arranged at the two end points and the corner of the L-shaped adapter frame 17. A limiting portion 16 for abutting against the first guide rod 21 is provided in each first slide slot 22, and the three first guide rods 21 and the three first slide slots 22 are respectively abutted at the three limiting portions 16, and the three limiting portions 16 can be connected to form a stable plane ( Fig.25 The dotted box in the figure) ensures that when the base frame 11 moves relative to the adapter frame 17 along the first direction (x direction), the base frame 11 can always be located in a plane, thereby preventing the optical axis of the lens on the base frame 11 from shifting and ensuring the shooting quality of the camera module.

[0216] In some embodiments, the limiting portion 16 may be an outward protruding structure disposed in the first slide groove 22. In other embodiments, the limiting portion 16 may also be a first guide rod 21, wherein the dimension of the first guide rod 21 along the first direction is smaller than the first slide groove 22. In the embodiment of the present application, the structure and the setting position of the limiting portion 16 are not further limited.

[0217] For example, Fig.26 As shown, the anti-shake bracket 18 is integrally formed with a second guide rod 23 extending along the second direction. Fig. 27As shown, a second slide slot 24 corresponding to the second guide rod 23 is formed on one side of the adapter frame 17 facing the anti-shake bracket 18. A second guide rod 23 is arranged in each second slide slot 24, and the second guide rod 23 and the second slide slot 24 are movably connected along the second direction.

[0218] Similarly, in the embodiment of the present application, the number of the second guide rods 23 and the second slide grooves 24 is also three, and the three second slide grooves 24 are respectively arranged at the end points and corners of the L-shaped adapter frame 17, and each second slide groove 24 is provided with a limiting portion 16 for abutting against the second guide rod 23, and the three second guide rods 23 and the three second slide grooves 24 are respectively abutted at the three limiting portions 16, and the three limiting portions 16 can be connected to form a stable plane ( Fig. 27 The dotted box in the figure) allows the base 11 to prevent the optical axis of the lens on the base 11 from shifting within a plane when the base 11 moves relative to the anti-shake bracket 18 along the second direction (y direction), thereby ensuring the shooting quality of the camera module.

[0219] By integrally forming the first guide rod 21 or the second guide rod 23 on the adapter frame 17, the base frame 11 or the anti-shake bracket 18, a separately set guide rod can be omitted. Compared with a structure in which a separate guide rod is set and then glued in a slide groove, the connection relationship between the guide rod and the adapter frame 17, the base frame 11 or the anti-shake bracket 18 is more stable, which can prevent the guide rod from falling off. This can simplify the structure of the adapter frame 17, the base frame 11 and the anti-shake bracket 18, and can simplify the assembly process, reduce the difficulty of assembly, and reduce costs.

[0220] In addition, it should be noted that the positions of the first guide rod 21 and the first slide groove 22 in the embodiment of the present application can be interchanged. For example, in some embodiments, Fig.24 and Fig.25 As shown, the first guide rod 21 can be arranged on the adapter frame 17, and the first slide slot 22 can be arranged on the base frame 11. In some other embodiments, as Fig.28 and Fig.29 As shown, the first slide groove 22 can be arranged on the adapter frame 17, and the first guide rod 21 can be arranged on the base frame 11. Therefore, the arrangement positions of the first guide rod 21 and the first slide groove 22 are not further limited in the embodiment of the present application.

[0221] Similarly, the second guide rod 23 and the second slide slot 24 can be interchanged. For example, in some embodiments, Fig.26 and Fig. 27 As shown, the second guide rod 23 may also be disposed on the adapter frame 17, and the second slide slot 24 may be disposed on the anti-shake bracket 18. In other embodiments, as Fig.30 and Fig.31As shown, the second guide rod 23 can be arranged on the anti-shake bracket 18, and the second slide slot 24 can be arranged on the adapter frame 17. Therefore, the arrangement positions of the second guide rod 23 and the second slide slot 24 are not further limited in the embodiment of the present application.

[0222] Continue to see Fig.19 As shown, the second driving component 19 includes a second magnetic element 191 and a second coil 192; wherein, the second coil 192 is arranged on the base frame 11, the second magnetic element 191 is arranged on the base frame 11, and the second magnetic element 191 and the second coil 192 are arranged relatively to each other; when the second coil 192 is energized, the second magnetic element 191 is driven to move, thereby driving the base frame 11 and the carrier 13 to move.

[0223] A second driving component 19 is provided to drive the base 11, and the second driving component 19 is provided to include a second magnetic element 191 and a second coil 192. When the second coil 192 is energized, the second magnetic element 191 can generate a driving force. By adjusting the current in the second coil 192, the moving direction and moving distance of the base 11 can be adjusted. In addition, the structures of the magnetic element and the coil are relatively simple and easy to set up. Therefore, the structure of the camera motor 100 can be simplified, thereby reducing costs.

In particular, the guide rail 14 is integrally formed on the carrier 13 or the base frame 11, so that the parts of the camera motor 100 can be reduced and the cost can be reduced while ensuring that the carrier 13 can move relative to the base frame 11 along the optical axis of the lens. Compared with setting the guide rail 14 separately, this can simplify the camera motor 100 and simplify the assembly process, thereby solving the problem of complex drive motor structure and cumbersome assembly process in the related art. In addition, by integrally forming the guide rail 14 on the carrier 13 or the base frame 11, the problem of the guide rail 14 loosening and falling off can also be solved. This simplifies the structure of the camera module, reduces costs, and increases the service life of the camera module.
