Motors, camera modules and electronic equipment

[0001] This application claims priority to the Chinese patent application with application number 202410396257.7 filed with the State Intellectual Property Office of China on March 30, 2024, and priority to the Chinese patent application with the invention name “Motor, camera module and electronic equipment”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of camera technology, and in particular to a motor, a camera module, and an electronic device. Background Art

[0003] With the popularity and development of smartphones, mobile photography has become a common method of photography, and smartphones with optical zoom functions are increasingly popular. Conventional motors with optical zoom functions include a base, a first carrier, a second carrier, and four ball groups. The bottom of the first carrier is movably connected to the bottom of the base via two ball groups, and the bottom of the second carrier is movably connected to the bottom of the base via two ball groups. This, on the one hand, occupies a large space in the XY plane due to the flattening of the four ball groups in the XY direction, hindering the miniaturization of the motor. On the other hand, the distance between the two ball groups connecting the bottom of the first carrier is large, resulting in poor connection stability between the first carrier and the base. Similarly, the distance between the two ball groups connecting the bottom of the second carrier is large, resulting in poor connection stability between the second carrier and the base. Therefore, there is a pressing need for a motor that can provide optical zoom functionality, achieve miniaturization, and ensure stability. Summary of the Invention

[0004] The embodiments of the present application provide a motor, a camera module, and an electronic device, aiming to obtain a motor that can have an optical zoom function, can be miniaturized, and can ensure stability.

[0005] In a first aspect, a motor is provided. The motor includes a base, a first carrier, a second carrier, a first drive mechanism, a second drive mechanism, a first connecting member, a second connecting member, a third connecting member, and a fourth connecting member;

[0006] The base includes a bottom, a first side portion, and a second side portion, the bottom is connected between the first side portion and the second side portion, and the first side portion and the second side portion are spaced apart along a first direction;

[0007] The first carrier is slidably connected to the first side portion via the first connecting member and the second connecting member, and the second carrier is slidably connected to the second side portion via the third connecting member and the fourth connecting member, and at least a portion of the first carrier and at least a portion of the second carrier are arranged along a second direction, and the second direction is different from the first direction;

[0008] The first driving mechanism is used to drive the first carrier to move relative to the base along the second direction, and the second driving mechanism is used to drive the second carrier to move relative to the base along the second direction.

[0009] It will be understood that in this embodiment, the first carrier can be slidably connected to the base via the first and second connecting members. In this case, the first carrier can drive the first lens mounted thereon to move along the X-axis. The second carrier can be slidably connected to the base via the third and fourth connecting members. The second carrier can drive the second lens mounted thereon to move along the X-axis. In this case, the first and second lenses move along the X-axis, thereby achieving focus and continuous optical zoom of the camera module.

[0010] In this embodiment, the first carrier is connected to the first side of the base through the first connecting member and the second connecting member, and the second carrier is connected to the second side of the base through the third connecting member and the fourth connecting member, thereby realizing a scheme in which the double-sided connecting members of the motor guide the first carrier and the second carrier respectively.

[0011] It is understandable that in one embodiment, the first carrier is connected to the bottom of the base through the first and second connectors, and the second carrier is connected to the bottom of the base through the third and fourth connectors. In this solution, since the first, second, third and fourth connectors are laid out flat on the XY plane, the first, second, third and fourth connectors occupy a large space in the XY plane, and the structural arrangement of the motor is not compact, which is not conducive to the miniaturization of the motor. In this embodiment, the first carrier is connected to the first side of the base through the first and second connectors, and the second carrier is connected to the second side of the base through the third and fourth connectors. The first and second connectors are arranged at intervals along the Z-axis direction, and the third and fourth connectors are arranged along the Z-axis direction. At this time, the first, second, third and fourth connectors occupy a small space in the XY plane, and the structural arrangement of the motor is relatively compact, which is conducive to the miniaturization of the motor.

[0012] It is understood that in one embodiment, the first carrier is connected to the bottom of the base via first and second connectors, and the second carrier is connected to the bottom of the base via third and fourth connectors. In this embodiment, to ensure the stability of the connection between the first carrier and the base, the first and second connectors must be located on either side of the first lens. In this case, the distance between the first and second connectors is inevitably significantly increased, and the stability of the connection between the first carrier and the base remains poor. Improving the stability of the connection between the first carrier and the base by increasing the magnetic force between the magnetic element and the magnetic member would inevitably increase the size of the magnetic element and the magnetic member. This would also significantly increase the size of the motor, which is not conducive to achieving a miniaturized motor. In contrast, in this embodiment, the first carrier is connected to the first side of the base via the first and second connectors, that is, the first and second connectors are located on the side of the base. This ensures the stability of the connection between the first carrier and the base while not being restricted by the first lens. In this case, the distance between the first and second connectors can be set to a smaller distance, which is conducive to achieving a miniaturized motor. Similarly, the third connecting member and the fourth connecting member are arranged in the same manner and have the same technical effect, and will not be described in detail here.

[0013] It is understood that in one embodiment, the first carrier and the second carrier are simultaneously connected to the base via the first, second, third, and fourth connectors. In this case, the first carrier and the second carrier are susceptible to jamming due to the non-parallel guides of the first, second, third, and fourth connectors. In contrast, in this embodiment, the first carrier is slidably connected to the base solely via the first and second connectors, and the second carrier is slidably connected to the base solely via the third and fourth connectors. The relative movement of the first and second carriers can be independent of each other. The first and second carriers are less likely to jam during movement.

[0014] In addition, in this embodiment, the first carrier is slidably connected to the base via the first and second connectors, and the second carrier is slidably connected to the base via the third and fourth connectors. The first and second connectors are positioned near the first side of the base, while the third and fourth connectors are positioned near the second side of the base. In this case, the connection points between the first carrier and the base and the second carrier are located on different sides of the base. This prevents the connection points between the first carrier and the base and the second carrier from interfering with each other.

[0015] In one possible implementation, the first connector and the second connector are spaced apart along a third direction, which is different from both the second and first directions. Thus, the first connector and the second connector are spaced apart along the Z-axis. In this case, the first, second, third, and fourth connectors occupy less space in the XY plane, resulting in a more compact motor structure and facilitating miniaturization.

[0016] Alternatively, the third and fourth connectors are spaced apart along a third direction, each of which is different from the second and first directions. Thus, the third and fourth connectors are arranged along the Z-axis. In this case, the first, second, third, and fourth connectors occupy less space in the XY plane, resulting in a more compact motor structure and facilitating miniaturization.

[0017] In a possible implementation, the first driving mechanism includes a first coil and a first magnetic member, the first coil is fixed to the first side portion, the first magnetic member is fixed to the first carrier, and the first coil is arranged facing the first magnetic member.

[0018] It can be understood that during the movement of the first carrier relative to the base, the movement direction of the first carrier is perpendicular to the magnetic gap between the first magnetic part and the first coil. The above-mentioned magnetic gap is not affected by the movement of the first carrier. Therefore, it can avoid the problem of rapid decrease in driving force due to the increase in the magnetic gap, thereby ensuring that the driving force of the motor is large and the driving force is relatively stable, which is beneficial to the focusing function of the motor or the large-stroke design of optical zoom.

[0019] In a possible implementation, the second driving mechanism includes a second coil and a second magnetic member, the second coil is fixed to the second side portion, the second magnetic member is fixed to the second carrier, and the second coil is arranged facing the second magnetic member.

[0020] It can be understood that during the movement of the second carrier relative to the base, the movement direction of the second carrier is perpendicular to the magnetic gap between the second magnetic part and the second coil. The above-mentioned magnetic gap is not affected by the movement of the second carrier. Therefore, it can avoid the problem of rapid decrease in driving force due to the increase in the magnetic gap, thereby ensuring that the driving force of the motor is large and the driving force is relatively stable, which is beneficial to the focusing function of the motor or the large-stroke design of optical zoom.

[0021] It is understood that in this embodiment, the first magnetic member is positioned near the first side of the base, and the second magnetic member is positioned near the second side of the base. The first and second magnetic members can be positioned on either side of the first and second lenses. In this way, magnetic interference between the first and second magnetic members is less likely to occur during movement of the first and second lenses.

[0022] In a possible implementation, the first connecting member and the second connecting member are fixed to the first side portion;

[0023] The motor also includes a first magnetic member, which is fixed to the first side portion and arranged facing the first magnetic member. The magnetic force between the first magnetic member and the first magnetic member maintains contact between the first side portion, the first connecting member, the second connecting member and the first carrier.

[0024] In one possible implementation, the size of the first magnetic member in the second direction is greater than the sum of the size of the first magnetic member in the second direction and the movement range of the first carrier in the second direction. In this way, on the one hand, it is conducive to achieving the minimum magnetic restoring force, and on the other hand, it is conducive to achieving self-locking at any position within the movement range of the first carrier in the X-axis direction. In other words, this embodiment can achieve that the first carrier can be stationary at the current target position when it is powered off (the first coil is not energized), that is, when the first carrier is at the target position, there is no need to continuously energize the first coil to maintain the current position, thereby achieving the purpose of reducing power consumption.

[0025] In a possible implementation, the first magnetic member is fixed to a side of the first side portion away from the first coil.

[0026] In a possible implementation, the first connecting member and the second connecting member are fixed to the first side portion;

[0027] The first connecting member is made of a magnetic conductive material, and the magnetic force between the first connecting member and the first magnetic member maintains contact between the first side portion, the first connecting member, the second connecting member and the first carrier; and / or, the second connecting member is made of a magnetic conductive material, and the magnetic force between the first connecting member and the first magnetic member maintains contact between the first side portion, the first connecting member, the second connecting member and the first carrier.

[0028] In a possible implementation, the relative magnetic permeability of the first connecting member may be greater than or equal to 1.1. In this way, the magnetic force between the first connecting member and the first magnetic member is relatively large, which is conducive to improving the pre-tightening ability between the first carrier and the first side portion of the base.

[0029] And / or, the relative magnetic permeability of the second connecting member may be greater than or equal to 1.1. In this way, the magnetic force between the second connecting member and the first magnetic member is relatively large, which is conducive to improving the pre-tightening ability between the first carrier and the first side portion of the base.

[0030] In one possible implementation, the dimension of the first connecting member in the second direction is greater than the sum of the dimension of the first magnetic member in the second direction and the travel range of the first carrier in the second direction. This facilitates, on the one hand, minimizing the magnetic restoring force, and, on the other hand, enabling self-locking at any position within the travel range of the first carrier in the X-axis direction. In other words, this embodiment allows the first carrier to remain stationary at its current target position when powered off (without power to the first coil). That is, when the first carrier is at the target position, there is no need to continuously power the first coil to maintain the current position, thereby reducing power consumption.

[0031] And / or, the size of the second connecting member in the second direction is greater than the sum of the size of the first magnetic member in the second direction and the movement range of the first carrier in the second direction. This is beneficial for achieving a minimum magnetic restoring force on the one hand, and for achieving self-locking at any position within the movement range of the first carrier in the X-axis direction on the other hand. In other words, this embodiment allows the first carrier to remain stationary at the current target position when powered off (the first coil is not energized). That is, when the first carrier is at the target position, there is no need to continuously energize the first coil to maintain the current position, thereby achieving the purpose of reducing power consumption.

[0032] In a possible implementation, the first connecting member and the second connecting member both adopt a sliding shaft structure, and the first connecting member and the second connecting member are both fixed to the first side portion;

[0033] The first carrier is provided with the first sliding groove and the second sliding groove which are spaced apart from each other. A portion of the first connecting member is located in the first sliding groove, and a portion of the second connecting member is located in the second sliding groove.

[0034] It is understood that when both the first and second connectors are guided by a sliding shaft structure, the first carrier is in linear contact with the first and second connectors during movement. This increases the contact area of ​​the first carrier, avoids the risk of dents caused by excessive impact pressure, and improves motor reliability.

[0035] In a possible implementation, one of the first chute and the second chute is a V-shaped groove, and the other is an L-shaped groove or a U-shaped groove.

[0036] It can be understood that by setting one of the first sliding groove and the second sliding groove as a "V"-shaped groove and the other as an "L"-shaped groove or a "U"-shaped groove, the cooperation between the first connecting member, the second connecting member and the first carrier can be achieved, including tight fit and loose fit, to reduce the difficulty of assembly.

[0037] In addition, the first carrier can ensure stable support of the first connecting member and the second connecting member through the mutual cooperation of the "V"-shaped groove and the "L"-shaped groove, or the mutual cooperation of the "V"-shaped groove and the "U"-shaped groove, and can ensure the stability of the movement of the first carrier.

[0038] In a possible implementation, the contact position between the first carrier and the first connector includes a first contact position and a second contact position, and the contact position between the first carrier and the second connector includes a third contact position;

[0039] The third contact position is opposite to the space between the first contact position and the second contact position.

[0040] It can be understood that by arranging the third contact position to correspond to the space between the first contact position and the second contact position, the first carrier and the base are better pre-tightened, thereby improving the stability between the first carrier and the base.

[0041] In one possible implementation, the motor includes a first sensor and a first magnetic grid. One of the first sensor and the first magnetic grid is fixed to the base, and the other is fixed to the first carrier. The first sensor is used to measure the magnetic difference of the first magnetic grid during the movement of the first carrier, and detect the position change of the first carrier in the second direction based on the magnetic difference. It can be understood that because the first sensor can be used to detect the position change of the first carrier in the X-axis direction, the accuracy of controlling the movement of the first carrier can be improved.

[0042] And / or, the motor includes a second sensor and a second magnetic grid, one of which is fixed to the base, and the other is fixed to the second carrier. The second sensor is configured to measure a magnetic difference of the second magnetic grid during movement of the second carrier, and to detect position changes of the second carrier in the second direction based on the magnetic difference. It will be appreciated that because the second sensor can be used to detect position changes of the second carrier in the second direction, the accuracy of controlling the movement of the second carrier can be improved.

[0043] In a possible implementation, the motor includes a motor circuit board and a driver chip, wherein the motor circuit board is fixed to the bottom of the base, and the driver chip is fixed to the motor circuit board;

[0044] The first coil is electrically connected to the motor circuit board through a conductive member, a spring or a flexible circuit board in the base, and is electrically connected to the driving chip through the motor circuit board. The driving chip is used to control the current of the first coil.

[0045] In a possible implementation, the motor includes the heat sink, and at least a portion of the heat sink is fixed to a side of the bottom of the base away from the motor circuit board;

[0046] The heat sink is used to dissipate heat generated by the driver chip, thereby preventing the local temperature inside the motor from being too high, which may lead to poor SFR of the first lens and / or the second lens.

[0047] In one possible implementation, the motor includes a housing comprising a top plate and side frames, the side frames being connected to the periphery of the top plate; the side frames being fixed to the bottom of the base, and the top plate and side frames jointly covering the first and second side portions of the base. Thus, the housing is assembled and mated with the base, with the housing cover being mounted on the base. The housing and base cooperate to encapsulate and protect the internal structures of the motor, such as the first carrier and the second carrier.

[0048] In a possible implementation, the first carrier includes a first fixing portion and a second fixing portion, and the second carrier includes a third fixing portion and a fourth fixing portion;

[0049] The first fixing portion and the third fixing portion are arranged at intervals along the second direction, the second fixing portion is arranged opposite to the first side portion, and the fourth fixing portion is arranged opposite to the second side portion;

[0050] The second fixing portion is slidably connected to the first side portion through the first connecting member and the second connecting member, and the fourth fixing portion is slidably connected to the second side portion through the third connecting member and the fourth connecting member.

[0051] In a possible implementation, the second fixing portion is located between the third fixing portion and the first side portion, and the fourth fixing portion is located between the first fixing portion and the second side portion. In this way, the arrangement between the base, the first carrier, and the second carrier is more compact.

[0052] In a possible implementation, the first fixing portion and the second fixing portion form an "L" shape, and / or the third fixing portion and the fourth fixing portion form an "L" shape.

[0053] In a second aspect, a camera module is provided. The camera module includes a lens assembly and an image sensor assembly, wherein the image sensor assembly is located on the image side of the lens assembly. The lens assembly includes a first lens, a second lens, and the motor described in the first aspect, wherein the first lens is mounted on a first carrier of the motor, and the second lens is mounted on a second carrier of the motor.

[0054] It can be understood that the motor of the camera module can not only have an optical zoom function, but also be miniaturized and ensure stability.

[0055] In a possible implementation, the camera module includes a first optical path conversion element, the first optical path conversion element is located on the object side of the lens assembly, and the first optical path conversion element is used to change the optical axis direction of the camera module;

[0056] And / or, the camera module includes a second optical path conversion element, which is located between the lens assembly and the image sensor assembly, and the second optical path conversion element is used to change the optical axis direction of the camera module.

[0057] In a third aspect, an electronic device is provided. The electronic device includes a device housing and the camera module described in the second aspect, wherein the camera module is disposed in the device housing. It is understood that the motor of the camera module can provide an optical zoom function, achieve a compact design, and ensure stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0092] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0093] The object side, with the lens as the boundary, the side where the object is located is the object side, and the surface of the lens close to the object side is called the object side;

[0094] Image side: With the lens as the boundary, the side where the image of the object is located is called the image side, and the surface of the lens close to the image side is called the image side;

[0095] The optical axis is an axis running perpendicularly through the center of a lens. It's the axis running through the centers of each lens element. When light rays parallel to the optical axis enter a convex lens, an ideal convex lens would have all the rays converge at a single point behind the lens. This point is the focal point.

[0096] In the description of this application, it should be noted that, unless otherwise specified or limited, the terms "installed," "connected," "connected," and "connected" should be understood broadly. For example, "connected" can be a detachable or non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an electrical connection or a mechanical connection. Among them, "fixed connection" means that the two parts are connected to each other and the relative positional relationship remains unchanged after the connection. "Moveable connection" means that the two parts are connected to each other and can move relative to each other after the connection, and the positional relationship can change. "Rotational connection" means that the two parts are connected to each other and can rotate relative to each other after the connection. "Sliding connection" means that the two parts are connected to each other and can slide relative to each other after the connection. In addition, two components are formed into an integrated structure through an integral molding process, which means that during the process of forming one of the two components, the component is connected to the other component, and the two components do not need to be connected by further processing (such as bonding, welding, snap connection, screw connection). Component A and component B can be arranged relative to each other so that component A is projected along the target direction to obtain projection C, and component B is projected along the target direction to obtain projection D, and projection C and projection D can at least partially overlap. In some embodiments, the majority overlap can be any of the following: projection C is completely within projection D. Alternatively, projection D is completely within projection C. Alternatively, projection C and projection D intersect each other, and the intersection area of ​​projection C and projection D accounts for more than 50% of projection C or projection D.

[0097] The directional terms mentioned in the embodiments of the present application, such as "top", "bottom", "inside", "outside", "upper", "lower", etc., are only used to refer to the directions in the drawings. Therefore, the directional terms used are for better and clearer description and understanding of the embodiments of the present application, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present application. For those skilled in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0098] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship. "Multiple" means at least two.

The electronic device 1000 of the embodiment shown in FIG1 is described using a mobile phone as an example.

[0101] For ease of description, the width direction of the electronic device 1000 is defined as the X-axis. The length direction of the electronic device 1000 is the Y-axis. The thickness direction of the electronic device 1000 is the Z-axis. It is understandable that the coordinate system setting of the electronic device 1000 can be flexibly set according to specific actual needs. In this embodiment, the Y-axis direction is defined as the first direction. The X-axis direction is the second direction. The Z-axis direction is the third direction. In other embodiments, the first direction, the second direction, and the third direction can be any direction of the coordinate system, as long as the first direction, the second direction, and the third direction are different from each other.

The light-transmitting portion 201 can be a light-transmitting hole or a transparent portion in the device housing 200. This application does not specifically limit the specific structure of the light-transmitting portion 201.

[0106] As shown in Figure 2, the camera module 100 includes a lens assembly 101 and an image sensor assembly 102. The image sensor assembly 102 is located on the image side of the lens assembly 101. The lens assembly 101 can be used to achieve focus and optical zoom. The image sensor assembly 102 can be used to convert image information carried by ambient light into electrical signals.

[0107] Exemplarily, the camera module 100 includes a first optical path conversion element 103. The first optical path conversion element 103 is located on the object side of the lens assembly 101. The first optical path conversion element 103 can be used to change the optical axis direction of the camera module 100. Exemplarily, the first optical path conversion element 103 can be used to change the Z-axis direction to the X-axis direction.

[0108] Exemplarily, the first optical path conversion element 103 may include a prism. It is understood that the present application does not limit the specific structure of the first optical path conversion element 103.

[0113] Fig. 3 is a schematic diagram of the structure of some embodiments of the lens assembly 101 shown in Fig. 2. Fig. 4 is a partially exploded schematic diagram 1 of some embodiments of the lens assembly 101 shown in Fig. 3.

[0114] As shown in Figures 3 and 4 , lens assembly 101 includes a motor 10, a first lens 20, and a second lens 30. It should be understood that Figures 3 and 4 merely schematically illustrate some of the components of lens assembly 101, and the actual shape, size, position, and configuration of these components are not limited by Figures 3 and 4 or the accompanying figures. For example, the first lens 20 and the second lens 30 may be lens structures comprising a lens barrel and lenses. The number of lenses in the first lens 20 and the second lens 30 is not specifically limited in this application.

[0115] For example, the first lens 20 and the second lens 30 are both mounted on the motor 10. The motor 10 can control the first lens 20 and the second lens 30 to move along the optical axis to achieve focusing and optical zoom. It is understood that the motor 10 can control the movement of the first lens 20 along the optical axis alone, the movement of the second lens 30 along the optical axis alone, or the movement of the first lens 20 and the second lens 30 along the optical axis simultaneously.

[0116] For example, the length direction of the motor 10 may be the X-axis. The width direction of the motor 10 may be the Y-axis. The thickness direction of the motor 10 may be the Z-axis. In other embodiments, the coordinate system of the motor 10 may be flexibly set according to specific practical needs.

[0126] Fig. 6 is an enlarged schematic diagram of the structure of some embodiments of the base 11 shown in Fig. 5. Fig. 7 is a schematic diagram of the structure of the base 11 shown in Fig. 6 at another angle.

[0127] As shown in Figures 6 and 7, the base 11 illustratively includes a bottom 111, a first side portion 112 and a second side portion 113 disposed opposite each other, and a third side portion 114 and a fourth side portion 115 disposed opposite each other. The bottom 111 is connected between the first side portion 112 and the second side portion 113, and is also connected between the third side portion 114 and the fourth side portion 115. In addition, the third side portion 114 and the fourth side portion 115 are also connected between the first side portion 112 and the second side portion 113. Exemplarily, the first side portion 112 and the second side portion 113 may be spaced apart along the Y-axis direction. The third side portion 114 and the fourth side portion 115 may be spaced apart along the X-axis direction.

[0128] In other embodiments, the base 11 may not include the third side portion 114 and the fourth side portion 115 .

[0129] It should be understood that although Figures 6 and 7 divide the base 11 into five parts, this does not affect the fact that the base 11 can be a one-piece structure. Furthermore, in other embodiments, the base 11 can also be formed from different independent structural components through an assembly process. For example, the first side portion 112 and the second side portion 113 of the base 11 can be two independent structural components fixed to the bottom 111 of the base 11 through welding, bonding, or other methods.

[0130] Exemplarily, the bottom 111 , the first side 112 , the second side 113 , the third side 114 and the fourth side 115 of the base 11 may enclose an installation space 116 .

[0131] For example, the first side portion 112 of the base 11 is provided with a first groove 1121 and a second groove 1122 spaced apart from each other. In one embodiment, the first groove 1121 and the second groove 1122 may be arranged along the Z-axis.

[0133] Exemplarily, the third side portion 114 of the base 11 is provided with a first through hole 1141 . The first through hole 1141 is communicated with the installation space 116 .

[0134] Exemplarily, the fourth side portion 115 of the base 11 is provided with a second through hole 1151 . The second through hole 1151 is communicated with the installation space 116 .

[0135] FIG8 is a first schematic diagram of a partial structure of some embodiments of the motor 10 shown in FIG4 .

[0136] As shown in FIG8 , the first coil 141 is fixed to the first side portion 112 of the base 11 . At least a portion of the first coil 141 may be located within the mounting space 116 .

[0137] 8 , the first and second connectors 16a and 16b are fixed to the first side portion 112 of the base 11 at intervals. At least a portion of the first and second connectors 16a and 16b may be located within the installation space 116.

[0138] Exemplarily, the first connecting member 16a and the second connecting member 16b are arranged at intervals along the Z-axis direction. In other embodiments, the arrangement of the first connecting member 16a and the second connecting member 16b is not specifically limited.

[0139] As shown in Figures 6 and 8, by way of example, the first connecting member 16a is fixed in the first groove 1121 of the base 11. A portion of the first connecting member 16a is exposed relative to the first groove 1121. The second connecting member 16b is fixed in the second groove 1122 of the base 11. A portion of the second connecting member 16b is exposed relative to the second groove 1122.

[0140] FIG9 is a schematic structural diagram of a portion of the motor 10 shown in FIG8 at another angle.

[0141] 9 , the second coil 151 is fixed to the second side portion 113 of the base 11 . At least a portion of the second coil 151 may be located within the mounting space 116 .

[0142] 9 , the third and fourth connectors 16c and 16d are fixed to the second side 113 of the base 11 at intervals. At least a portion of the third and fourth connectors 16c and 16d may be located within the installation space 116.

[0143] Exemplarily, the third connecting member 16c and the fourth connecting member 16d are arranged at intervals along the Z-axis direction. In other embodiments, the arrangement of the third connecting member 16c and the fourth connecting member 16d is not specifically limited.

[0144] As shown in Figures 7 and 9, by way of example, the third connecting member 16c is fixed within the third groove 1131 of the base 11. A portion of the third connecting member 16c is exposed relative to the third groove 1131. The fourth connecting member 16d is fixed within the fourth groove 1132 of the base 11. A portion of the fourth connecting member 16d is exposed relative to the fourth groove 1132.

[0145] Please refer to FIG. 8 and FIG. 9 , and in combination with FIG. 5 , the circuit board assembly 17 is fixed to the base 11 , and at least a portion thereof may be located within the installation space 116 .

[0146] Exemplarily, the motor circuit board 171 is fixed to the bottom 111 of the base 11. A portion of the motor circuit board 171 is located within the mounting space 116, while a portion passes through the first side portion 112 and / or the second side portion 113 and is disposed outside the base 11. The driver chip 172, the first sensor 173, and the second sensor 174 can be disposed within the mounting space 116.

[0147] Exemplarily, the first coil 141 can be electrically connected to the motor circuit board 171 through a conductive member in the base 11, and electrically connected to the driver chip 172 through the motor circuit board 171. The conductive member can be formed in the base 11 by an insert molding process. In other embodiments, the first coil 141 can be electrically connected to the motor circuit board 171 through a flexible circuit board or a spring, and electrically connected to the driver chip 172 through the motor circuit board 171. In other embodiments, the shape of the motor circuit board 171 can be adaptively changed so that the first coil 141 is fixed to the motor circuit board 171 and directly electrically connected to the motor circuit board 171. It is understandable that the driver chip 172 can control the current condition of the first coil 141 (for example, whether current is flowing or the magnitude of the current when power is flowing).

[0148] It is understood that the manner in which the second coil 151 is electrically connected to the driver chip 172 can be similar to the manner in which the first coil 141 is electrically connected to the driver chip 172. The details will not be repeated here. In this case, the driver chip 172 can also control the current flow in the second coil 151 (e.g., whether current is flowing or the magnitude of the current when it is flowing).

[0149] Fig. 10 is an enlarged schematic diagram of the structure of some embodiments of the first carrier 12 shown in Fig. 5. Fig. 11 is a schematic diagram of the structure of the first carrier 12 shown in Fig. 10 at another angle.

[0150] As shown in Figures 10 and 11 , the first carrier 12 includes a first fixing portion 121 and a second fixing portion 122. It is understood that although Figures 10 and 11 divide the first carrier 12 into two parts, this does not affect the fact that the first carrier 12 can be an integrally formed structure.

[0151] For example, the first carrier 12 may be in an “L” shape, that is, the first fixing portion 121 and the second fixing portion 122 may form an “L” shape.

[0152] Exemplarily, the first fixing portion 121 is provided with a first mounting hole 1211 .

[0153] Exemplarily, the second fixing portion 122 is provided with a first mounting groove 1221 .

[0154] For example, the second fixing portion 122 is provided with a first slide groove 1222 and a second slide groove 1223 spaced apart from each other. The first slide groove 1222 and the second slide groove 1223 can be located on either side of the first mounting groove 1221, that is, the first mounting groove 1221 is located between the first slide groove 1222 and the second slide groove 1223. The first slide groove 1222 and the second slide groove 1223 can extend in the X-axis direction.

[0155] FIG. 12 is a partially exploded schematic diagram of some embodiments of the first carrier 12 shown in FIG. 10 .

[0156] As shown in Figure 12, the first carrier 12 includes a first main body 12a and a first cover plate 12b. The first cover plate 12b can be fixed to the first main body 12a and, together with the first main body 12a, define a first mounting hole 1211. For example, the first cover plate 12b can be fixedly connected to the first main body 12a by bonding, welding, or the like.

[0157] It can be understood that since the first carrier 12 is formed by assembling the first main body 12a and the first cover plate 12b, when the first carrier 12 is assembled with other structural parts, the first main body 12a can be assembled with the other structural parts first, and then the first cover plate 12b can be fixed to the first main body 12a to fix the other structural parts to the first carrier 12.

[0158] FIG. 13 is a second schematic diagram of a partial structure of some embodiments of the motor 10 shown in FIG. 4 .

[0159] 13 , in conjunction with FIG10 and FIG11 , the first magnetic member 142 is fixed to the first carrier 12 . Exemplarily, the first magnetic member 142 is located in the first mounting groove 1221 .

[0160] It is understood that the first magnetic member 142 can be fixed to the first magnetic conductive member 143, and the first magnetic conductive member 143 can be fixed to the first carrier 12. In this case, the first magnetic member 142 can be fixed to the first carrier 12 via the first magnetic conductive member 143 (see Figure 5). For example, at least a portion of the first magnetic conductive member 143 can be embedded in the first carrier 12.

[0161] Exemplarily, the first magnetic member 142 may include one or more magnets, and the implementation structure of the first magnetic member 142 may be various. For example, in some embodiments, the first magnetic member 142 is a Halbach magnet array. In other embodiments, the first magnetic member 142 may adopt a dual magnet solution, for example, consisting of two magnets, the two magnets are arranged in the X-axis direction, and the polarity directions are opposite. In other embodiments, the first magnetic member 142 may adopt a single magnet solution, for example, consisting of a magnet, the magnet including two parts with opposite polarity directions. The magnet can be made using a bipolar magnetization process. It is understandable that the polarity direction can be the direction of the north pole (N) toward the south pole (S), or the direction of the south pole (S) toward the north pole (N).

[0162] Fig. 14 is a third schematic diagram of a portion of the structure of some embodiments of the motor 10 shown in Fig. 4. Fig. 15 is a partial cross-sectional view of a portion of the motor 10 shown in Fig. 14 taken along line BB in one embodiment.

[0163] Referring to Figures 14 and 15 , in conjunction with Figures 8 and 13 , in some embodiments, at least a portion of the first carrier 12 is positioned within the mounting space 116 of the base 11. The first guide groove 1222 of the first carrier 12 corresponds to the first groove 1121 of the base 11, and the second guide groove 1223 of the first carrier 12 corresponds to the second groove 1122 of the base 11. A portion of the first connector 16a is positioned within the first guide groove 1222, while a portion of the second connector 16b is positioned within the second guide groove 1223. The first carrier 12 is slidably connected to the base 11 via the first connector 16a and the second connector 16b. The relative sliding direction between the first and second connectors 16a and 16b is parallel to the guide direction of the first and second connectors 16a and 16b, i.e., the X-axis direction. Among them, when the first connecting member 16a and the second connecting member 16b both adopt a sliding shaft structure, the axial direction of the sliding shaft is the guiding direction of the first connecting member 16a and the second connecting member 16b; when the first connecting member 16a and the second connecting member 16b both adopt a ball structure, the arrangement direction of the multiple balls is the guiding direction of the first connecting member 16a and the second connecting member 16b.

[0164] Exemplarily, the second fixing portion 122 of the first carrier 12 is slidably connected to the first side portion 112 of the base 11 through the first connecting member 16 a and the second connecting member 16 b .

[0165] It is understood that when both the first connecting member 16a and the second connecting member 16b are guided by a sliding shaft structure, the first carrier 12 is in line contact with the first connecting member 16a and the second connecting member 16b during movement. This increases the contact area of ​​the first carrier 12, thereby preventing the risk of dents caused by excessive impact pressure and improving the reliability of the motor 10.

[0166] In some embodiments, the first and second connectors 16a, 16b, and the first carrier 12 can be fitted with either a tight fit or a loose fit to reduce assembly difficulty. For example, as shown in Figure 15, the first chute 1222 of the first carrier 12 can be a V-shaped groove. The second chute 1223 of the first carrier 12 can be an L-shaped groove or a U-shaped groove. When the V-shaped groove is fitted with the first connector 16a, the side walls of the first chute 1222 can contact the first connector 16a, achieving a tight fit. When the L-shaped groove or the U-shaped groove is fitted with the second connector 16b, the bottom walls of the second chute 1223 can contact the second connector 16b, achieving a loose fit. In other embodiments, the shapes of the first and second chute 1223 of the first carrier 12 can be reversed, that is, the first chute 1222 of the first carrier 12 can be an L-shaped groove or a U-shaped groove, and the second chute 1223 can be a V-shaped groove.

[0167] In addition, the first carrier 12 can ensure the stable support of the first connecting member 16a and the second connecting member 16b through the mutual cooperation of the "V"-shaped groove and the "L"-shaped groove, or the mutual cooperation of the "V"-shaped groove and the "U"-shaped groove, thereby ensuring the stability of the movement of the first carrier 12.

[0168] Fig. 16A is a schematic diagram of a portion of the structure of some embodiments of the lens assembly 101 shown in Fig. 3. Fig. 16B is a partial cross-sectional view of a portion of the lens assembly 101 shown in Fig. 16A at line CC in one embodiment.

[0169] As shown in Figures 16A and 16B, illustratively, the first mounting hole 1211 of the first carrier 12 is used to mount the first lens 20. In some embodiments, the first coil 141 is arranged facing the first magnetic member 142, and is used to drive the first carrier 12 to move relative to the base 11 along the X-axis direction. When the first carrier 12 moves relative to the base 11 along the X-axis direction, the first carrier 12 can drive the first lens 20 mounted thereon to move along the X-axis direction. The first coil 141 is arranged facing the first magnetic member 142, which means that the winding plane of the first coil 141 faces the first magnetic member 142.

[0170] In this embodiment, during the movement of the first carrier 12 relative to the base 11, the movement direction of the first carrier 12 is perpendicular to the magnetic gap between the first magnetic member 142 and the first coil 141. The above-mentioned magnetic gap is not affected by the movement of the first carrier 12. Therefore, the problem of a rapid decrease in driving force due to an increase in the magnetic gap can be avoided, thereby ensuring that the driving force of the motor 10 is large and relatively stable, which is beneficial to the focusing function of the motor 10 or the large-stroke design of optical zoom.

[0171] Among them, the first magnetic part 142 can have two opposite polarity directions, and the polarity direction of the first magnetic part 142 is set perpendicular to the winding plane of the first coil 141. Among them, the coils in the two sections of the first coil 141 can be respectively set to correspond to the two polarity directions of the first magnetic part 142, and the currents in the coils in the two sections flow in opposite directions. At this time, the side of the first magnetic part 142 facing the first coil 141 includes the North Pole (N) and the South Pole (S), and the side of the first magnetic part 142 facing away from the first coil 141 correspondingly includes the South Pole (S) and the North Pole (N).

[0172] FIG. 17 is an enlarged schematic diagram of the structure of some embodiments of the second carrier 13 shown in FIG. 5 .

[0173] As shown in Figure 17 , the second carrier 13 includes a third fixing portion 131 and a fourth fixing portion 132. It is understood that although Figure 17 divides the second carrier 13 into two parts, it does not affect the fact that the second carrier 13 can be an integrally formed structure.

[0174] Exemplarily, the second carrier 13 may be in an “L” shape.

[0175] Exemplarily, the third fixing portion 131 is provided with a second mounting hole 1311 .

[0176] Exemplarily, the fourth fixing portion 132 is provided with a second mounting groove 1321 .

[0177] For example, the fourth fixing portion 132 is provided with a third slide groove 1322 and a fourth slide groove 1323 spaced apart from each other. The third slide groove 1322 and the fourth slide groove 1323 may be located on either side of the second mounting groove 1321, that is, the second mounting groove 1321 is located between the third slide groove 1322 and the fourth slide groove 1323. The third slide groove 1322 and the fourth slide groove 1323 may extend in the X-axis direction.

[0178] FIG. 18 is a partially exploded schematic diagram of some embodiments of the second carrier 13 shown in FIG. 17 .

[0179] As shown in Figure 18, the second carrier 13 includes a second main body 13a and a second cover plate 13b. The second cover plate 13b can be fixed to the second main body 13a and, together with the second main body 13a, define a second mounting hole 1311. For example, the second cover plate 13b can be fixedly connected to the second main body 13a by bonding, welding, or the like.

[0180] It can be understood that since the second carrier 13 is formed by assembling the second main body 13a and the second cover 13b, when the second carrier 13 is assembled with other structural parts, the second main body 13a can be assembled with the other structural parts first, and then the second cover 13b can be fixed to the second main body 13a to fix the other structural parts to the second carrier 13.

[0181] FIG19 is a fourth schematic diagram of a partial structure of some embodiments of the motor 10 shown in FIG4 .

[0182] 19 , in combination with FIG17 , the second magnetic member 152 is fixed to the second carrier 13 . Exemplarily, the second magnetic member 152 is located in the second mounting groove 1321 .

[0183] It is understood that the second magnetic member 152 can be fixed to the second magnetic conductive member 153 (see FIG5 ), and the second magnetic conductive member 153 (see FIG5 ) can be fixed to the second carrier 13. In this case, the second magnetic member 152 can be fixed to the second carrier 13 via the second magnetic conductive member 153 (see FIG5 ). For example, at least a portion of the second magnetic member 152 (see FIG5 ) can be embedded in the first carrier 12.

[0184] Exemplarily, the second magnetic member 152 may include one or more magnets, and the implementation structure of the second magnetic member 152 may be various. For example, in some embodiments, the second magnetic member 152 may adopt a dual magnet solution, for example, consisting of two magnets, the two magnets are arranged in the X-axis direction, and the polarity directions are opposite. In other embodiments, the second magnetic member 152 is a Halbach magnet array. In other embodiments, the second magnetic member 152 may adopt a single magnet solution, for example, consisting of a magnet, the magnet including two parts with opposite polarity directions. The magnet can be made using a bipolar magnetization process.

[0185] Fig. 20 is a fifth schematic diagram of a portion of the structure of some embodiments of the motor 10 shown in Fig. 4. Fig. 21 is a partial cross-sectional view of a portion of the motor 10 shown in Fig. 20 taken along line DD in one embodiment.

[0186] Referring to FIG. 20 and FIG. 21 , and in combination with FIG. 9 and FIG. 19 , in some embodiments, at least a portion of the second carrier 13 may be located within the installation space 116 of the base 11 .

[0187] For example, the first fixing portion 121 of the first carrier 12 and the third fixing portion 131 of the second carrier 13 can be arranged along the X-axis. In other words, at least a portion of the first carrier 12 and at least a portion of the second carrier 13 can be arranged along the X-axis. Furthermore, the second fixing portion 122 of the first carrier 12 is disposed opposite the first side portion 112 of the base 11. The fourth fixing portion 132 of the second carrier 13 is disposed opposite the second side portion 113 of the base 11.

[0188] For example, the second fixing portion 122 of the first carrier 12 is located between the third fixing portion 131 of the second carrier 13 and the first side portion 112 of the base 11. The fourth fixing portion 132 of the second carrier 13 is located between the first fixing portion 121 of the first carrier 12 and the second side portion 113 of the base 11. In this way, the arrangement of the base 11, the first carrier 12, and the second carrier 13 is more compact.

[0189] It can be understood that the second fixing portion 122 of the first carrier 12 is located between the third fixing portion 131 of the second carrier 13 and the first side portion 112 of the base 11, which includes two situations: one is that during the movement of the first carrier 12 relative to the base 11, and / or the movement of the second carrier 13 relative to the base 11, the second fixing portion 122 of the first carrier 12 can always be located between the third fixing portion 131 of the second carrier 13 and the first side portion 112 of the base 11; the other is that during the movement of the first carrier 12 relative to the base 11, and / or the movement of the second carrier 13 relative to the base 11, the second fixing portion 122 of the first carrier 12 can be located between the third fixing portion 131 of the second carrier 13 and the first side portion 112 of the base 11 at a certain moment or for a period of time. Similarly, the explanation that the fourth fixing portion 132 of the second carrier 13 is located between the first fixing portion 121 of the first carrier 12 and the second side portion 113 of the base 11 can also refer to the explanation that the second fixing portion 122 of the first carrier 12 is located between the third fixing portion 131 of the second carrier 13 and the first side portion 112 of the base 11.

[0190] In other embodiments, the relative positions of the first carrier 12 and the second carrier 13 are not specifically limited.

[0191] Exemplarily, a central axis of the first fixing portion 121 of the first carrier 12 in the X-axis direction coincides with a central axis of the third fixing portion 131 of the second carrier 13 in the X-axis direction.

[0192] Referring to Figures 20 and 21 , in conjunction with Figures 9 and 19 , the third slide groove 1322 of the second carrier 13 corresponds to the third groove 1131 of the base 11, and the fourth slide groove 1323 of the second carrier 13 corresponds to the fourth groove 1132 of the base 11. A portion of the third connector 16c is positioned within the third slide groove 1322, while a portion of the fourth connector 16d is positioned within the fourth slide groove 1323. The second carrier 13 is slidably connected to the base 11 via the third and fourth connectors 16c, 16d. The relative sliding direction between the second carrier 13 and the base 11 is parallel to the guide direction of the third and fourth connectors 16c, 16d, i.e., the X-axis direction. Among them, when the third connecting member 16c and the fourth connecting member 16d both adopt a sliding shaft structure, the axial direction of the sliding shaft is the guiding direction of the third connecting member 16c and the fourth connecting member 16d; when the third connecting member 16c and the fourth connecting member 16d both adopt a ball structure, the arrangement direction of the multiple balls is the guiding direction of the third connecting member 16c and the fourth connecting member 16d.

[0193] Exemplarily, the fourth fixing portion 132 of the second carrier 13 is slidably connected to the second side portion 113 of the base 11 through the third connecting member 16 c and the fourth connecting member 16 d .

[0194] It is understood that when the third connecting member 16c and the fourth connecting member 16d are both guided by a sliding shaft structure, the second carrier 13 is in linear contact with the third connecting member 16c and the fourth connecting member 16d during movement. This increases the contact area of ​​the second carrier 13, thereby reducing the risk of dents caused by excessive impact pressure and improving the reliability of the motor 10.

[0195] In some embodiments, the cooperation between the third connecting member 16c and the fourth connecting member 16d and the second carrier 13 includes a tight fit and a loose fit to reduce the difficulty of assembly. For example, as shown in Figure 21, the third chute 1322 of the second carrier 13 can be a "V"-shaped groove. The fourth chute 1323 of the second carrier 13 can be an "L"-shaped groove or a "U"-shaped groove. When the "V"-shaped groove cooperates with the third connecting member 16c, the side groove wall of the third chute 1322 can contact the third connecting member 16c, achieving a tight fit. When the "L"-shaped groove or the "U"-shaped groove cooperates with the fourth connecting member 16d, the bottom groove wall of the fourth chute 1323 can contact the fourth connecting member 16d, achieving a loose fit.

[0196] In addition, the second carrier 13 can ensure the stable support of the third connecting member 16c and the fourth connecting member 16d through the mutual cooperation of the "V"-shaped groove and the "L"-shaped groove, or the mutual cooperation of the "V"-shaped groove and the "U"-shaped groove, thereby ensuring the stability of the movement of the second carrier 13.

[0197] Fig. 22A is a second schematic diagram of a portion of the structure of some embodiments of the lens assembly 101 shown in Fig. 3. Fig. 22B is a partial cross-sectional view of a portion of the lens assembly 101 shown in Fig. 22A taken along line EE in one embodiment.

[0198] As shown in Figures 22A and 22B, illustratively, the second mounting hole 1311 of the second carrier 13 is used to mount the second lens 30. The second lens 30 can be located on the image side of the first lens 20. In some embodiments, the second coil 151 is arranged facing the second magnetic member 152, and is used to drive the second carrier 13 to move relative to the base 11 along the X-axis direction. When the second carrier 13 moves relative to the base 11 along the X-axis direction, the second carrier 13 can drive the second lens 30 mounted thereon to move along the X-axis direction. The second coil 151 is arranged facing the second magnetic member 152, which means that the winding plane of the second coil 151 faces the second magnetic member 152.

[0199] In this embodiment, during the movement of the second carrier 13 relative to the base 11, the movement direction of the second carrier 13 is perpendicular to the magnetic gap between the second magnetic member 152 and the second coil 151. The above-mentioned magnetic gap is not affected by the movement of the second carrier 13. Therefore, the problem of a rapid decrease in driving force due to an increase in the magnetic gap can be avoided, thereby ensuring that the driving force of the motor 10 is large and relatively stable, which is beneficial to the focusing function of the motor 10 or the large-stroke design of optical zoom.

[0200] The second magnetic member 152 may have two opposite polarity directions, and the polarity direction of the second magnetic member 152 is arranged perpendicular to the winding plane of the second coil 151. The coils in the two sections of the second coil 151 may be arranged corresponding to the two polarity directions of the second magnetic member 152, and the currents in the coils in the two sections flow in opposite directions. The side of the second magnetic member 152 facing the second coil 151 includes a north pole (N) and a south pole (S), and the side of the second magnetic member 152 facing away from the second coil 151 includes a south pole (S) and a north pole (N).

[0201] It will be appreciated that in this embodiment, the first magnetic member 142 is disposed near the first side portion 112 of the base 11, and the second magnetic member 152 is disposed near the second side portion 113 of the base 11. The first magnetic member 142 and the second magnetic member 152 can be located on either side of the first lens 20 and the second lens 30. In this way, magnetic interference between the first magnetic member 142 and the second magnetic member 152 is less likely to occur during the movement of the first lens 20 and the second lens 30.

[0202] The above text specifically introduces the specific structure of the base 11, the first carrier 12 and the second carrier 13, as well as the specific connection method, in conjunction with the relevant drawings. It can be understood that in this embodiment, the first carrier 12 can be slidably connected to the base 11 through the first connecting member 16a and the second connecting member 16b. At this time, the first carrier 12 can drive the first lens 20 mounted thereon to move along the X-axis direction. The second carrier 13 can be slidably connected to the base 11 through the third connecting member 16c and the fourth connecting member 16d. The second carrier 13 can drive the second lens 30 mounted thereon to move along the X-axis direction. At this time, the first lens 20 and the second lens 30 move along the X-axis direction, thereby achieving focus and continuous optical zoom of the camera module 100.

[0203] Furthermore, in this embodiment, the first carrier 12 is connected to the first side portion 112 of the base 11 via the first connector 16a and the second connector 16b, and the second carrier 13 is connected to the second side portion 113 of the base 11 via the third connector 16c and the fourth connector 16d, thereby enabling the motor 10's dual-sided connectors to guide the first carrier 12 and the second carrier 13, respectively. For example, the first connector 16a, the second connector 16b, the third connector 16c, and the fourth connector 16d all utilize sliding shafts. In this manner, the camera module 100 can utilize the motor 10's dual-sided sliding shafts to guide the first carrier 12 and the second carrier 13, respectively.

[0204] It is understood that in one embodiment, the first carrier 12 is connected to the bottom 111 of the base 11 via the first and second connectors 16a, 16b, and the second carrier 13 is connected to the bottom 111 of the base 11 via the third and fourth connectors 16c, 16d. In this embodiment, to ensure the stability of the connection between the first carrier 12 and the base 11, the first and second connectors 16a, 16b must be located on either side of the first lens 20. In this case, the distance between the first and second connectors 16a, 16b is inevitably significantly increased, and the stability of the connection between the first carrier 12 and the base 11 remains poor. Improving the stability of the connection between the first carrier 12 and the base 11 by increasing the magnetic force between the magnetic element and the magnetic component would inevitably increase the size of the magnetic element and the magnetic component. This would also significantly increase the size of the motor 10, hindering the miniaturization of the motor 10. In this embodiment, the first carrier 12 is connected to the first side portion 112 of the base 11 via the first connector 16a and the second connector 16b. Specifically, the first connector 16a and the second connector 16b are located on the side edges of the base 11. This ensures a stable connection between the first carrier 12 and the base 11 while freeing the first and second connectors 16a, 16b from being affected by the first lens 20. Furthermore, the distance between the first and second connectors 16a, 16b can be reduced, facilitating a compact design for the motor 10. Similarly, the third and fourth connectors 16c, 16d employ the same configuration and achieve the same technical effects. Details will not be elaborated upon here.

[0205] It is understood that in one embodiment, the first carrier 12 is connected to the bottom 111 of the base 11 via the first connector 16a and the second connector 16b, and the second carrier 13 is connected to the bottom 111 of the base 11 via the third connector 16c and the fourth connector 16d. In this embodiment, because the first connector 16a, the second connector 16b, the third connector 16c, and the fourth connector 16d are arranged flat on the XY plane, the first connector 16a, the second connector 16b, the third connector 16c, and the fourth connector 16d occupy a large space on the XY plane, resulting in a non-compact structural arrangement of the motor 10, which is not conducive to the miniaturization of the motor 10. In this embodiment, the first carrier 12 is connected to the first side portion 112 of the base 11 via a first connector 16a and a second connector 16b, and the second carrier 13 is connected to the second side portion 113 of the base 11 via a third connector 16c and a fourth connector 16d. The first connector 16a and the second connector 16b are spaced apart along the Z-axis, while the third connector 16c and the fourth connector 16d are arranged along the Z-axis. In this configuration, the first connector 16a, the second connector 16b, the third connector 16c, and the fourth connector 16d occupy less space in the XY plane, resulting in a more compact structure for the motor 10, which facilitates miniaturization of the motor 10.

[0206] It is understood that in one embodiment, the first carrier 12 and the second carrier 13 are simultaneously connected to the base 11 via the first connector 16a, the second connector 16b, the third connector 16c, and the fourth connector 16d. In this case, the first carrier 12 and the second carrier 13 are susceptible to getting stuck due to the non-parallel guides of the first connector 16a, the second connector 16b, the third connector 16c, and the fourth connector 16d. In this embodiment, the first carrier 12 is slidably connected to the base 11 solely via the first connector 16a and the second connector 16b, and the second carrier 13 is slidably connected to the base 11 solely via the third connector 16c and the fourth connector 16d. The relative movement of the first carrier 12 and the second carrier 13 can be independent of each other. The first carrier 12 and the second carrier 13 are less likely to get stuck during movement.

[0207] In addition, in this embodiment, the first carrier 12 is slidably connected to the base 11 via the first connector 16a and the second connector 16b, and the second carrier 13 is slidably connected to the base 11 via the third connector 16c and the fourth connector 16d. The first connector 16a and the second connector 16b are positioned near the first side 112 of the base 11, while the third connector 16c and the fourth connector 16d are positioned near the second side 113 of the base 11. In this case, the connection points between the first carrier 12 and the base 11 and the connection points between the second carrier 13 and the base 11 are located on different sides of the base 11. In this way, the connection points between the first carrier 12 and the base 11 and the connection points between the second carrier 13 and the base 11 are less likely to interfere with each other.

[0208] Fig. 23 is a third partially exploded schematic diagram of some embodiments of the lens assembly 101 shown in Fig. 3. Fig. 24 is a partial cross-sectional diagram of some embodiments of the lens assembly 101 shown in Fig. 3 at line FF.

[0209] As shown in Figures 23 and 24, in some embodiments, the first magnetic member 181 is fixed to the first side portion 112 of the base 11, for example, it can be located on the side of the first side portion 112 of the base 11 away from the first coil 141. The first magnetic member 181 is arranged to face the first magnetic member 142. The magnetic force between the first magnetic member 181 and the first magnetic member 142 causes the first carrier 12 to tend to approach the first side portion 112 of the base 11, thereby ensuring that the first side portion 112 of the base 11, the first connecting member 16a, the second connecting member 16b, and the first carrier 12 maintain contact, thereby achieving pre-tightening.

[0210] Exemplarily, the first side portion 112 of the base 11 is provided with a first fixing slot 1123 . The first magnetic member 181 is disposed in the first fixing slot 1123 .

[0211] As shown in Figures 23 and 24, in some embodiments, the second magnetic member 182 is fixed to the second side portion 113 of the base 11, for example, it can be located on the side of the second side portion 113 of the base 11 away from the second coil 151. The second magnetic member 182 is arranged to face the second magnetic member 152. The magnetic force between the second magnetic member 182 and the second magnetic member 152 causes the second carrier 13 to tend to approach the second side portion 113 of the base 11, thereby ensuring that the base 11, the second connecting member 16b, the second connecting member 16b, and the second carrier 13 maintain contact, thereby achieving pre-tightening.

[0212] Exemplarily, the second side portion 113 of the base 11 defines a second fixing slot 1133 . The second magnetic member 182 is disposed in the second fixing slot 1133 .

[0213] Fig. 25 is a fourth partially exploded schematic diagram of some embodiments of the lens assembly 101 shown in Fig. 3. Fig. 26 is a partially exploded schematic diagram of the lens assembly 101 shown in Fig. 25 at another angle.

[0214] As shown in Figures 25 and 26, for example, the dimension L1 of the first magnetic member 181 in the X-axis direction is greater than the sum of the dimension L2 of the first magnetic member 142 in the X-axis direction and the movement stroke L3 of the first carrier 12 in the X-axis direction, that is, L1>L2+L3. The first magnetic member 181 protrudes on both sides of the first magnetic member 142 in the X-axis direction. During the focusing or optical zooming process of the motor 10, the first magnetic member 181 and the first magnetic member 142 can still maintain a facing relationship or an almost facing relationship, thereby ensuring the stability of the magnetic attraction. Among them, the projection of the first magnetic member 181 on the XZ plane covers the projection of the first magnetic member 142 on the XZ plane in the X-axis direction, and the two can be considered to be in a facing relationship.

[0215] It is understood that by setting the dimension L1 of the first magnetic member 181 in the X-axis direction to be greater than the sum of the dimension L2 of the first magnetic member 142 in the X-axis direction and the movement range L3 of the first carrier 12 in the X-axis direction, it is beneficial to minimize the magnetic restoring force on the one hand, and to achieve self-locking at any position within the movement range of the first carrier 12 in the X-axis direction on the other hand. In other words, this embodiment allows the first carrier 12 to remain stationary at the current target position when powered off (the first coil 141 is not energized). That is, when the first carrier 12 is in the target position, there is no need to continuously energize the first coil 141 to maintain the current position, thereby achieving the purpose of reducing power consumption.

[0216] As shown in Figures 25 and 26, for example, the dimension H1 of the second magnetic member 182 in the X-axis direction is greater than the sum of the dimension H2 of the second magnetic member 152 in the X-axis direction and the movement stroke H3 of the second carrier 13 in the X-axis direction, that is, H1>H2+H3. The second magnetic member 182 protrudes on both sides of the second magnetic member 152 in the X-axis direction. During the focusing or optical zooming process of the motor 10, the second magnetic member 182 and the second magnetic member 152 can still maintain a facing relationship or an almost facing relationship, thereby ensuring the stability of the magnetic attraction. Among them, the projection of the second magnetic member 182 on the XZ plane covers the projection of the second magnetic member 152 on the XZ plane in the X-axis direction, and the two can be considered to be in a facing relationship.

[0217] It is understood that by setting the dimension H1 of the second magnetic member 182 in the X-axis direction to be greater than the sum of the dimension H2 of the second magnetic member 152 in the X-axis direction and the movement range H3 of the second carrier 13 in the X-axis direction, it is beneficial to minimize the magnetic restoring force on the one hand, and to achieve self-locking at any position within the movement range of the second carrier 13 in the X-axis direction on the other hand. In other words, this embodiment allows the second carrier 13 to remain stationary at the current target position when powered off (the second coil 151 is not energized). That is, when the second carrier 13 is in the target position, there is no need to continuously energize the second coil 151 to maintain the current position, thereby achieving the purpose of reducing power consumption.

[0218] It is understandable that in some other embodiments, the size, shape and position of the first magnetic member 181 and the second magnetic member 182 may also be adjusted, and the embodiment of the present application does not strictly limit this.

[0219] It is understood that the above description describes pre-tightening the first carrier 12 and the first side portion 112 of the base 11 by fixing the first magnetic member 181 to the first side portion 112 of the base 11 and utilizing the magnetic force between the first magnetic member 181 and the first magnetic member 142. A method for pre-tightening the first carrier 12 and the first side portion 112 of the base 11 will be described in detail below with reference to the relevant drawings.

[0220] As shown in Figures 24 to 26, the first connecting member 16a adopts a sliding shaft structure and is made of a magnetic conductive material, such as silicon steel sheets, various iron products and alloys formed by rare earth elements.

[0221] It can be understood that the magnetic force between the first connecting member 16a and the first magnetic member 142 causes the first carrier 12 to tend to approach the first side portion 112 of the base 11, thereby ensuring that the first side portion 112 of the base 11, the first connecting member 16a, the second connecting member 16b and the first carrier 12 maintain contact and achieve pre-tightening.

[0222] In one embodiment, the relative magnetic permeability of the first connecting member 16a may be greater than or equal to 1.1. In this way, the magnetic force between the first connecting member 16a and the first magnetic member 142 is relatively strong, which is conducive to improving the pre-tightening ability between the first carrier 12 and the first side portion 112 of the base 11.

[0223] In one embodiment, the size of the first connecting member 16a in the X-axis direction is greater than the sum of the size of the first magnetic member 142 in the X-axis direction and the travel range of the first carrier 12 in the X-axis direction. This helps minimize the magnetic restoring force and enables self-locking at any position within the travel range of the first carrier 12 in the X-axis direction. In other words, this embodiment allows the first carrier 12 to remain stationary at the current target position when powered off (without power to the first coil 141). That is, when the first carrier 12 is in the target position, there is no need to continuously power the first coil 141 to maintain the current position, thereby reducing power consumption.

[0224] It is understood that the second connecting member 16b adopts a sliding shaft structure. The second connecting member 16b can also be made of a magnetic conductive material. The magnetic force between the second connecting member 16b and the first magnetic member 142 can further cause the first carrier 12 to have a tendency to approach the first side portion 112 of the base 11, thereby further ensuring that the first side portion 112 of the base 11, the first connecting member 16a, the second connecting member 16b and the first carrier 12 maintain contact, thereby achieving pre-tightening.

[0225] In one embodiment, the relative magnetic permeability of the second connecting member 16b may be greater than or equal to 1.1. In this way, the magnetic force between the second connecting member 16b and the first magnetic member 142 is relatively strong, which is conducive to improving the pre-tightening ability between the first carrier 12 and the first side portion 112 of the base 11.

[0226] In one embodiment, the size of the second connecting member 16 b in the X-axis direction is larger than the sum of the size of the first magnetic member 142 in the X-axis direction and the movement stroke of the first carrier 12 in the X-axis direction.

[0227] As shown in Figures 24 to 26, the third connecting member 16c adopts a sliding shaft structure. The third connecting member 16c can also be made of a magnetic conductive material. Specifically, the configuration of the third connecting member 16c can refer to the configuration of the first connecting member 16a. This will not be repeated here. Furthermore, the fourth connecting member 16d adopts a sliding shaft structure. The fourth connecting member 16d can also be made of a magnetic conductive material. Specifically, the configuration of the fourth connecting member 16d can refer to the configuration of the second connecting member 16b. This will not be repeated here.

[0228] Fig. 27 is a partially exploded schematic diagram 5 of some embodiments of the lens assembly 101 shown in Fig. 3. Fig. 28 is a partial cross-sectional view of some other embodiments of the lens assembly 101 shown in Fig. 3 at line FF.

[0229] As shown in Figures 27 and 28, in some embodiments, the first sensor 173 is fixed to the bottom 111 of the base 11 through the motor circuit board 171. The first sensor 173 can be welded to the first pad to achieve structural fixation and electrical connection. The first sensor 173 can be used to detect the position change of the first carrier 12 in the X-axis direction. The first sensor 173 can be a Hall sensor or a tunnel magneto-resistance (TMR) sensor. The following description takes the first sensor 173 as a TMR sensor as an example.

[0230] As shown in Figures 27 and 28, in some embodiments, the motor 10 further includes a first magnetic grid 184. The first magnetic grid 184 is fixed to the first carrier 12. For example, the length of the first magnetic grid 184 can be parallel to the direction of motion of the first carrier 12 (i.e., the X-axis direction). For example, the first magnetic grid 184 can be fixed to the second fixing portion 122 of the first carrier 12.

[0231] In this embodiment, the first sensor 173 can be used to measure the magnetic difference of the first magnetic grid 184 during the movement of the first carrier 12 , and detect the position change of the first carrier 12 in the X-axis direction through the magnetic difference.

[0232] In other embodiments, the motor 10 may not include the first magnetic grid 184. In this case, the first sensor 173 can directly measure the magnetic difference of the first magnetic member 142 during the movement of the first carrier 12 and detect the position change of the first carrier 12 in the X-axis direction through the magnetic difference.

[0233] FIG29 is a partial cross-sectional view of the lens assembly 101 shown in FIG3 at line GG in some embodiments.

[0234] As shown in Figures 27 and 29 , in some embodiments, a second sensor 174 is fixed to the bottom 111 of the base 11 via the motor circuit board 171. The second sensor 174 can be soldered to a second pad to achieve structural fixation and electrical connection. The second sensor 174 can be used to detect position changes of the second carrier 13 in the X-axis direction. The second sensor 174 can be a Hall effect sensor or a tunnel magnetoresistive sensor. The following description uses a TMR sensor as an example.

[0235] As shown in Figures 27 and 29, in some embodiments, the motor 10 further includes a second magnetic grid 185. The second magnetic grid 185 is fixed to the second carrier 13. For example, the length of the second magnetic grid 185 can be parallel to the direction of motion of the second carrier 13 (i.e., the X-axis direction). For example, the second magnetic grid 185 can be fixed to the fourth fixing portion 132 of the second carrier 13.

[0236] In this embodiment, the second sensor 174 can be used to measure the magnetic difference of the second magnetic grid 185 during the movement of the second carrier 13, and detect the position change of the second carrier 13 in the X-axis direction through the magnetic difference.

[0237] In other embodiments, the motor 10 may not include the second magnetic grid 185. In this case, the second sensor 174 can directly measure the magnetic difference of the second magnetic member 152 during the movement of the second carrier 13 and detect the position change of the second carrier 13 in the X-axis direction through the magnetic difference.

[0238] Fig. 30 is a sixth partially exploded schematic diagram of some embodiments of the lens assembly 101 shown in Fig. 3. Fig. 31 is a partial cross-sectional view of an embodiment of the lens assembly 101 shown in Fig. 3 taken along line HH.

[0239] As shown in Figures 30 and 31 , in some embodiments, the housing 19 includes a top plate 191 and side frames 192. The side frames 192 are connected to the periphery of the top plate 191.

[0240] As shown in Figures 30 and 31, in some embodiments, the housing 19 is assembled and matched with the base 11, and the housing 19 is covered on the base 11. Exemplarily, the side frame 192 of the housing 19 is fixed to the bottom 111 of the base 11. The top plate 191 and the side frame 192 of the housing 19 can jointly cover the first side portion 112, the second side portion 113, the third side portion 114, and the fourth side portion 115 of the base 11. The housing 19 cooperates with the base 11 to jointly encapsulate and protect the internal structure of the motor 10, such as the first carrier 12, the second carrier 13, the first lens 20, the second lens 30, and a portion of the circuit board assembly 17.

[0241] In one embodiment, the side frame 192 of the housing 19 can be fixed to the bottom 111 of the base 11 by one or more methods such as bonding, welding, and snapping.

[0242] In one embodiment, the top plate 191 of the housing 19 may also be fixed to the first side portion 112, the second side portion 113, the third side portion 114, and the fourth side portion 115 of the base 11. For example, the top plate 191 of the housing 19 may be fixed to the first side portion 112, the second side portion 113, the third side portion 114, and the fourth side portion 115 of the base 11 by adhesive.

[0243] In one embodiment, the side frame 192 of the housing 19 may also be fixed to the first side portion 112, the second side portion 113, the third side portion 114, and the fourth side portion 115 of the base 11. For example, the side frame 192 of the housing 19 may be fixed to the first side portion 112, the second side portion 113, the third side portion 114, and the fourth side portion 115 of the base 11 by adhesive.

[0244] As shown in Figures 30 and 31 , in some embodiments, the heat sink 183 includes a base plate 1831, a first side plate 1832, and a second side plate 1833. The first side plate 1832 and the second side plate 1833 are disposed opposite each other. The base plate 1831 is connected between the first side plate 1832 and the second side plate 1833. The second side plate 1833 is provided with a clearance hole 1834. The clearance hole 1834 can be used to provide clearance for the motor circuit board 171 extending outside the base 11.

[0245] It is understandable that the heat sink 183 may include more or fewer structures. For example, the heat sink 183 includes fewer structures. Exemplarily, the heat sink 183 may also not include the first side plate 1832 and / or the second side plate 1833. For another example, the heat sink 183 includes more structures. Exemplarily, the heat sink 183 includes a third side plate (not shown) and a fourth side plate (not shown) that are relatively arranged. The third side plate (not shown) and the fourth side plate (not shown) are connected to the bottom plate 1831 and are connected between the first side plate 1832 and the second side plate 1833.

[0246] As shown in Figures 30 and 31 , at least a portion of heat sink 183 is secured to a side of bottom 111 of base 11, away from motor circuit board 171. Heat sink 183 dissipates heat generated by driver chip 172, thereby preventing localized overheating within motor 10 that could lead to poor spatial frequency response (SFR) of first lens 20 and / or second lens 30. In other words, heat sink 183 dissipates heat from driver chip 172.

[0247] Illustratively, the bottom plate 1831 of the heat sink 183 is fixed to a side of the bottom 111 of the base 11 away from the motor circuit board 171. The first side plate 1832 of the heat sink 183 is fixed to a side of the side frame 192 of the housing 19 away from the first side portion 112 of the base 11. The second side plate 1833 of the heat sink 183 is fixed to a side of the side frame 192 of the housing 19 away from the second side portion 113 of the base 11. In other embodiments, the size, shape, and position of the heat sink 183 can also be adjusted as needed, and this embodiment of the present application is not strictly limited to this.

[0250] As shown in FIG32 , in some embodiments, the contact positions between the first carrier 12 and the first connector 16a include a first contact position M1 (the area enclosed by the dashed line in FIG32 ) and a second contact position M2 (the area enclosed by the dashed line in FIG32 ). The contact positions between the first carrier 12 and the second connector 16b include a third contact position M3 (the area enclosed by the dashed line in FIG32 ). The third contact position M3 is located directly in the space between the first contact position M1 and the second contact position M2.

[0251] It is understood that the first contact position M1 and the second contact position M2 can be formed by providing the first protrusion and the second protrusion in the first slide groove 1222 so as to be higher than other positions in the first slide groove 1222. Similarly, the third contact position M3 can be formed by providing the third protrusion in the second slide groove 1223 so as to be higher than other positions in the second slide groove 1223.

[0252] It is understandable that by setting the third contact position M3 to correspond to the space between the first contact position M1 and the second contact position M2 , the first carrier 12 and the base 11 are better pre-tightened, thereby improving the stability between the first carrier 12 and the base 11 .

[0253] It is understandable that the contact manner between the second carrier 13 and the third and fourth connectors 16c and 16d can refer to the contact manner between the first carrier 12 and the first and second connectors 16a and 16b, which will not be described in detail here.

[0254] It is understood that the above description combines the relevant drawings to introduce several structures of the motor 10. The following description will introduce several more structures of the motor 10.

[0255] For example, in each of the above embodiments, the first coil 141 is fixed to the first side portion 112 of the base 11. The first magnetic member 142 is fixed to the first carrier 12.

This application does not limit this in detail.

[0257] For another example, in each of the above embodiments, the motor 10 includes a first carrier 12 and a second carrier 13. The first carrier 12 and the second carrier 13 are each independently slidably connected to different positions of the base 11. In other embodiments, the motor 10 may further include more carriers. For example, the motor 10 may further include a third carrier (not shown), a fourth carrier (not shown), ..., and a Pth carrier (not shown). Where P is an integer greater than 2. The third carrier (not shown), the fourth carrier (not shown), ..., and the Pth carrier (not shown) are all used to carry lenses, thereby achieving the movement of multiple lenses. In addition, the third carrier (not shown), the fourth carrier (not shown), ..., and the Pth carrier (not shown) are also each independently slidably connected to different positions of the base 11. The connection method of the third carrier (not shown), the fourth carrier (not shown), ..., and the Pth carrier (not shown) to the base 11 can refer to the connection method of the first carrier 12 and the second carrier 13 to the base 11. The details will not be repeated here. It is understandable that the third carrier (not shown), the fourth carrier (not shown), ..., and the Pth carrier (not shown) cooperate with the first carrier 12 and the second carrier 13 to achieve focus and optical zoom of the camera module 100. This application does not limit this in detail.

The first connecting member 16a and the second connecting member 16b are slidably connected to the base 11. In other embodiments, the third connecting member 16c and the fourth connecting member 16d may also be fixed to the second carrier 13. The third connecting member 16c and the fourth connecting member 16d are slidably connected to the base 11. This application does not limit this in detail.

[0259] For another example, in other embodiments, the positions of the first sensor 173 and the first magnetic grid 184 may be reversed. In other words, the first sensor 173 is fixed to the first carrier 12. The first magnetic grid 184 is fixed to the bottom 111 of the base 11. In other embodiments, the positions of the second sensor 174 and the second magnetic grid 185 may also be reversed. In other words, the second sensor 174 is fixed to the second carrier 13. The second magnetic grid 185 is fixed to the bottom 111 of the base 11. This application does not limit this in detail.
