Description

Motors, camera modules and electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202410396257.7, filed with the China National Intellectual Property Administration on March 30, 2024, entitled "Motor, Camera Module and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of camera technology, and in particular to a motor, camera module, and electronic device. Background Technology

[0003] With the widespread adoption and development of smartphones, mobile phone photography has become a common way for people to take pictures, and phones with optical zoom capabilities are increasingly popular. Traditional motors with optical zoom capabilities include a base, a first carrier, a second carrier, and four ball bearing groups. The bottom of the first carrier is movably connected to the bottom of the base via two ball bearing groups, and the bottom of the second carrier is also movably connected to the bottom of the base via two ball bearing groups. This design has several drawbacks. First, because the four ball bearing groups are laid out flat in the XY direction, they occupy a large amount of space in the XY plane, which is detrimental to motor miniaturization. Second, the distance between the two ball bearing groups connecting to the bottom of the first carrier is relatively large, resulting in poor connection stability between the first carrier and the base; similarly, the distance between the two ball bearing groups connecting to the bottom of the second carrier is relatively large, leading to poor connection stability between the second carrier and the base. Therefore, it is particularly urgent to develop a motor that can achieve optical zoom capabilities, miniaturization, and stable operation. Summary of the Invention

[0004] This application provides a motor, a camera module, and an electronic device, aiming to obtain a motor that can have optical zoom function, achieve miniaturization, and 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 connector, a second connector, a third connector, and a fourth connector;

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

[0007] The first carrier is slidably connected to the first side via the first connector and the second connector, and the second carrier is slidably connected to the second side via the third connector and the fourth connector. At least a portion of the first carrier and at least a portion of the second carrier are arranged along a second direction, which 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] Understandably, in this embodiment, the first carrier can be slidably connected to the base via the first connector and the second connector. 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 connector and the fourth connector. The second carrier can drive the second lens mounted thereon to move along the X-axis. Thus, by moving the first and second lenses along the X-axis, focusing and continuous optical zoom of the camera module are achieved.

[0010] In this embodiment, the first carrier is connected to the first side of the base via the first connector and the second connector, and the second carrier is connected to the second side of the base via the third connector and the fourth connector, thereby realizing a scheme in which the two-sided connectors of the motor guide the first carrier and the second carrier respectively.

[0011] Understandably, in one embodiment, the first carrier is connected to the bottom of the base via a first and a second connector, and the second carrier is connected to the bottom of the base via a third and a fourth connector. In this embodiment, because the first, second, third, and fourth connectors are laid flat on the XY plane, they occupy a large amount of space in the XY plane, resulting in a non-compact motor structure and hindering motor miniaturization. In this embodiment, the first carrier is connected to the first side of the base via the first and second connectors, and the second carrier is connected to the second side of the base via the third and fourth connectors. The first and second connectors are spaced apart along the Z-axis, and the third and fourth connectors are also spaced along the Z-axis. This reduces the space occupied by the first, second, third, and fourth connectors in the XY plane, resulting in a more compact motor structure and facilitating motor miniaturization.

[0012] Understandably, in one embodiment, a first carrier is connected to the bottom of the base via a first connector and a second connector, and a second carrier is connected to the bottom of the base via a third connector and a fourth connector. In this embodiment, to ensure the connection stability between the first carrier and the base, the first connector and the second connector need to be located on opposite sides of the first lens. This inevitably increases the distance between the first connector and the second connector significantly, resulting in poor connection stability. If the connection stability is improved by increasing the magnetic force between the magnetic attractor and the magnetic component, the size of the magnetic attractor and the magnetic component will inevitably increase. This would also significantly increase the size of the motor, hindering its miniaturization. In this embodiment, the first carrier is connected to the first side of the base via the first connector and the second connector, meaning the first connector and the second connector are located on the side of the base. This ensures the connection stability between the first carrier and the base while freeing the first connector and the second connector from the influence of the first lens. Therefore, the distance between the first connector and the second connector can be smaller, which is beneficial for miniaturizing the motor. Similarly, the third and fourth connectors use the same configuration and achieve the same technical effect. Details will not be elaborated here.

[0013] Understandably, in one embodiment, the first carrier and the second carrier are simultaneously connected to the base via a first connector, a second connector, a third connector, and a fourth connector. In this case, the first and second carriers are prone to jamming due to the non-parallel guidance of the first, second, third, and fourth connectors. However, 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 movements 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] Furthermore, in this embodiment, the first carrier is slidably connected to the base via a first connector and a second connector, and the second carrier is slidably connected to the base via a third connector and a fourth connector. The first and second connectors are disposed near the first side of the base, and the third and fourth connectors are disposed near the second side of the base. In this case, the connection positions of the first carrier and the base, and the connection positions of the second carrier and the base, are located on different sides of the base. This prevents the connection positions of the first carrier and the base, and the connection positions of the second carrier and the base, from interfering with each other.

[0015] In one possible implementation, the first and second connectors are spaced apart along a third direction, which is different from both the second and first directions; thus, the first and second connectors 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, which is beneficial for miniaturizing the motor.

[0016] And / or, the third and fourth connectors are arranged at intervals along a third direction, 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, which is beneficial for miniaturizing the motor.

[0017] In one possible implementation, the first driving mechanism includes a first coil and a first magnetic element, the first coil being fixed to the first side, the first magnetic element being fixed to the first carrier, and the first coil being disposed facing the first magnetic element.

[0018] It is understandable that during the movement of the first carrier relative to the base, the direction of movement of the first carrier is perpendicular to the magnetic gap between the first magnetic component and the first coil. The magnetic gap is not affected by the movement of the first carrier, thus avoiding the problem of rapid decrease in driving force caused by the increase of magnetic gap. This ensures that the driving force of the motor is large and relatively stable, which is beneficial to the motor's focusing function or the large stroke design of optical zoom.

[0019] In one possible implementation, the second driving mechanism includes a second coil and a second magnetic element, the second coil being fixed to the second side, the second magnetic element being fixed to the second carrier, and the second coil being disposed facing the second magnetic element.

[0020] It is understandable that during the movement of the second carrier relative to the base, the direction of movement of the second carrier is perpendicular to the magnetic gap between the second magnetic component and the second coil. The magnetic gap is not affected by the movement of the second carrier, thus avoiding the problem of rapid decrease in driving force caused by the increase of magnetic gap. This ensures that the driving force of the motor is large and relatively stable, which is beneficial to the motor's focusing function or the large stroke design of optical zoom.

[0021] It is understood that in this embodiment, the first magnetic component is disposed near the first side of the base, and the second magnetic component is disposed near the second side of the base. The first and second magnetic components can be located on opposite sides of the first and second lenses. In this way, magnetic interference between the first and second magnetic components is less likely to occur during the movement of the first and second lenses.

[0022] In one possible implementation, the first connector and the second connector are fixed to the first side;

[0023] The motor further includes a first magnetic element, which is fixed to the first side and faces the first magnetic element. The magnetic force between the first magnetic element and the first magnetic element keeps the first side, the first connector, the second connector and the first carrier in contact.

[0024] In one possible implementation, the dimension of the first magnetic element in the second direction is greater than the sum of the dimension of the first magnetic element in the second direction and the travel distance of the first carrier in the second direction. This minimizes the magnetic restoring force and allows the first carrier to self-lock at any position within its travel distance along the X-axis. In other words, this embodiment allows the first carrier to remain stationary at its current target position when powered off (without energizing the first coil), meaning that when the first carrier is at the target position, it is not necessary to continuously energize the first coil to maintain its current position, thereby reducing power consumption.

[0025] In one possible implementation, the first magnetic element is fixed to the side of the first side that is away from the first coil.

[0026] In one possible implementation, the first connector and the second connector are fixed to the first side;

[0027] The first connector is made of a magnetically conductive material, and the magnetic force between the first connector and the first magnetic component keeps the first side, the first connector, the second connector, and the first carrier in contact; and / or, the second connector is made of a magnetically conductive material, and the magnetic force between the first connector and the first magnetic component keeps the first side, the first connector, the second connector, and the first carrier in contact.

[0028] In one possible implementation, the relative permeability of the first connector can be greater than or equal to 1.1. This results in a larger magnetic force between the first connector and the first magnetic element, which is beneficial for improving the pre-tightening capability between the first carrier and the first side of the base.

[0029] And / or, the relative permeability of the second connector can be greater than or equal to 1.1. This results in a larger magnetic force between the second connector and the first magnetic component, which is beneficial for improving the pre-tightening capability between the first carrier and the first side of the base.

[0030] In one possible implementation, the dimension of the first connector in the second direction is greater than the sum of the dimension of the first magnetic component in the second direction and the travel distance of the first carrier in the second direction. This is beneficial in two ways: firstly, it minimizes the magnetic restoring force; secondly, it allows the first carrier to achieve self-locking at any position within its travel distance in the X-axis direction. In other words, this embodiment allows the first carrier to remain stationary at the current target position when it is powered off (without energizing the first coil). That is, when the first carrier is at the target position, it is not necessary to continuously energize the first coil to maintain the current position, thereby reducing power consumption.

[0031] And / or, the dimension of the second connector in the second direction is greater than the sum of the dimension of the first magnetic component in the second direction and the travel distance of the first carrier in the second direction. This is beneficial in two ways: firstly, it minimizes the magnetic restoring force; secondly, it allows the first carrier to achieve self-locking at any position within its travel distance 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 energizing the first coil), meaning that when the first carrier is at the target position, it is not necessary to continuously energize the first coil to maintain its current position, thereby reducing power consumption.

[0032] In one possible implementation, both the first connector and the second connector adopt a sliding shaft structure, and both the first connector and the second connector are fixed to the first side.

[0033] The first carrier is provided with a first groove and a second groove that are spaced apart, a portion of the first connector is located in the first groove, and a portion of the second connector is located in the second groove.

[0034] Understandably, when both the first and second connecting parts use a sliding shaft structure for guidance, the first carrier makes line contact with both the first and second connecting parts during movement. This results in a larger contact area for the first carrier, avoiding the risk of dents caused by excessive impact pressure and improving the reliability of the motor.

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

[0036] It is understandable that by setting one of the first slide groove and the second slide groove to be a "V" shaped groove and the other to be an "L" shaped groove or a "U" shaped groove, the fit between the first connector, the second connector and the first carrier can be achieved, including tight fit and loose fit, so as to reduce the assembly difficulty.

[0037] Furthermore, the first carrier, through the cooperation of "V" shaped grooves and "L" shaped grooves, or the cooperation of "V" shaped grooves and "U" shaped grooves, can ensure the stable support of the first connecting member and the second connecting member, and thus ensure the stability of the movement of the first carrier.

[0038] In one 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 directly opposite the space between the first contact position and the second contact position.

[0040] It is understandable that by setting the third contact position directly opposite the space between the first and second contact positions, the first carrier and the base can be 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 grating. One of the first sensor and the first magnetic grating 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 grating during the movement of the first carrier, and to detect the position change of the first carrier in the second direction by means of the magnetic difference. It is understood that since 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 the second sensor and the second magnetic grating, one of which is fixed to the base and the other to the second carrier. The second sensor is used to measure the magnetic difference of the second magnetic grating during the movement of the second carrier, and to detect the position change of the second carrier in the second direction by means of the magnetic difference. It is understood that since the second sensor can be used to detect the position change of the second carrier in the second direction, the accuracy of controlling the movement of the second carrier can be improved.

[0043] In one 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 element, spring, or flexible circuit board in the base, and is electrically connected to the driver chip through the motor circuit board. The driver chip is used to control the current of the first coil.

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

[0046] The heat sink is used to dissipate the heat generated by the driver chip. This prevents excessively high local temperatures inside the motor, which could lead to SFR defects in 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 connected to the periphery of the top plate. The side frames are fixed to the bottom of the base, and the top plate and side frames together cover a first and a second side of the base. Thus, the housing and base are assembled and fitted together, with the housing covering the base. The housing and base cooperate to encapsulate and protect the internal structure of the motor, such as a first carrier, a second carrier, etc.

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

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

[0050] The second fixing part is slidably connected to the first side via the first connector and the second connector, and the fourth fixing part is slidably connected to the second side via the third connector and the fourth connector.

[0051] In one possible implementation, the second fixing part is located between the third fixing part and the first side part, and the fourth fixing part is located between the first fixing part and the second side part. This results in a more compact arrangement of the base, the first carrier, and the second carrier.

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

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

[0054] Understandably, the camera module's motor is designed to have optical zoom capabilities, be miniaturized, and ensure stability.

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

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

[0057] Thirdly, an electronic device is provided. The electronic device includes a device housing and a camera module as described in the second aspect, the camera module being disposed within the device housing. It is understood that the motor of the camera module can possess optical zoom capabilities, achieve miniaturization, and ensure stability. Attached Figure Description

[0092] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0093] The object side is defined by the lens; the side where the object is located is called the object side, and the surface of the lens closest to the object side is called the object side surface.

[0094] The image side is the side on which the image of the subject is located, with the lens as the boundary. The surface of the lens closest to the image side is called the image side surface.

[0095] The optical axis is a perpendicular axis passing through the center of a lens. The lens optical axis is the axis passing through the centers of all the lenses in the lens. When light rays parallel to the optical axis enter a convex lens, an ideal convex lens should have all the light rays converging at a single point behind the lens; this point where all the light rays converge is called the focal point.

For example, "joining" can be a detachable connection or a 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. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Movable connection" refers to a connection where the relative positional relationship can change after connection. "Rotary connection" refers to a connection where the relative positional relationship can change. "Sliding connection" refers to a connection where the relative positional relationship can change. Furthermore, the integrated structure obtained by a one-piece molding process means that during the formation of one of the two components, that component is connected to the other component without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to connect the two components. Components A and B can be arranged relative to each other such 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, with projection C and projection D at least largely overlapping. In some embodiments, the majority overlap can be any of the following: projection C is entirely within projection D; or projection D is entirely within projection C; or 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 this application, such as "top," "bottom," "inner," "outer," "upper," and "lower," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0098] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship. "Multiple" means at least two.

[0099] Figure 1 is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of this application.

[0100] As shown in Figure 1, the electronic device 1000 can be a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR headset, virtual reality (VR) glasses, or VR headset, or any other device with camera functionality. The electronic device 1000 in the embodiment shown in Figure 1 is illustrated 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 defined as the Y-axis. The thickness direction of the electronic device 1000 is defined as the Z-axis. It is understood that the coordinate system of the electronic device 1000 can be flexibly set according to specific practical needs. In this embodiment, the Y-axis direction is defined as the first direction, the X-axis direction as the second direction, and the Z-axis direction as the third direction. In other embodiments, the first direction, the second direction, and the third direction can be any direction of this coordinate system, as long as they are different from each other. Specifically, this embodiment does not impose any limitations.

[0102] Figure 2 is a partial cross-sectional view of the electronic device 1000 shown in Figure 1 on line AA in one embodiment.

[0103] As shown in Figures 1 and 2, the electronic device 1000 may include a camera module 100, a device housing 200, and a screen 300. The camera module 100 can be a rear-facing camera module or a front-facing camera module. Both Figures 1 and 2 schematically illustrate the camera module 100 using dashed boxes. It is understood that Figure 1 and the related figures below only schematically show some components included in the electronic device 1000, and the actual shape, size, position, and structure of these components are not limited by Figure 1 and the figures below. Furthermore, when the electronic device 1000 is a device of other forms, the electronic device 1000 may not include the screen 300.

[0104] As shown in Figures 1 and 2, in some embodiments, the screen 300 is mounted on the device housing 200 and together with the device housing 200 encloses the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house components of the electronic device 1000, such as a battery, receiver, or microphone. The screen 300 can be a flat screen or a curved screen.

[0105] For example, the camera module 100 can be located inside the electronic device 1000. The device housing 200 has a light-transmitting portion 201. The shape of the light-transmitting portion 201 is not limited to the circle shown in Figure 1, but can also be elliptical or irregular in shape. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting portion 201. The camera module 100 can capture the light entering the interior of the electronic device 1000. The light-transmitting portion 201 can be a light-transmitting hole or a transparent part 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 focusing and optical zoom. The image sensor assembly 102 can be used to convert image information carried by ambient light into electrical signals.

[0107] For example, 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. For example, the first optical path conversion element 103 can be used to change the Z-axis direction to the X-axis direction.

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

[0109] In other embodiments, the camera module 100 may not include the first optical path conversion element 103. The light-transmitting part 201, the lens assembly 101, and the image sensor assembly 102 may be arranged sequentially along the Z-axis.

[0110] Exemplarily, the camera module 100 also includes a second optical path conversion element 104. The second optical path conversion element 104 is located between the lens assembly 101 and the image sensor assembly 102. The second optical path conversion element 104 can also be used to change the optical axis direction of the camera module 100. Exemplarily, the second optical path conversion element 104 can be used to change the X-axis direction to the Z-axis direction.

[0111] For example, the second optical path conversion element 104 may include a prism. It is understood that this application does not limit the specific structure of the second optical path conversion element 104.

[0112] In other embodiments, the camera module 100 may not include the second optical path conversion element 104. The lens assembly 101 and the image sensor assembly 102 may be arranged sequentially along the X-axis.

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

[0114] As shown in Figures 3 and 4, the lens assembly 101 includes a motor 10, a first lens 20, and a second lens 30. It is understood that Figures 3 and 4 only schematically illustrate some components of the lens assembly 101, and the actual shape, size, position, and construction of these components are not limited by Figures 3 and 4 or the following figures. Exemplarily, the first lens 20 and the second lens 30 may be lens structures including a lens barrel and lens elements. The number of lens elements in the first lens 20 and the second lens 30 is not specifically limited in this application.

[0115] For example, both the first lens 20 and the second lens 30 are mounted on the motor 10. The motor 10 can control the movement of the first lens 20 and the second lens 30 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 independently, or it can control the movement of the second lens 30 along the optical axis independently, or it can control 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 can be the X-axis. The width direction of the motor 10 can be the Y-axis. The thickness direction of the motor 10 can be the Z-axis. In other embodiments, the coordinate system of the motor 10 can be flexibly set according to specific actual needs.

[0117] For example, the motor 10 can control the first lens 20 and / or the second lens 30 to move along the X-axis.

[0118] Figure 5 is a partially exploded view of some embodiments of the motor 10 shown in Figure 4.

[0119] As shown in Figure 5, the motor 10 includes a base 11, a first carrier 12, a second carrier 13, a first drive mechanism 14, a second drive mechanism 15, a first connector 16a, a second connector 16b, a third connector 16c, and a fourth connector 16d. It is understood that Figures 3 and 4 only schematically show some components of the motor 10, and the actual shape, size, position, and structure of these components are not limited to those shown in Figure 5. It is understood that the first connector 16a, the second connector 16b, the third connector 16c, and the fourth connector 16d can be either a sliding shaft structure or a ball bearing structure. This embodiment is described using the example of the first connector 16a, the second connector 16b, the third connector 16c, and the fourth connector 16d being sliding shafts.

[0120] For example, the first driving mechanism 14 includes a first coil 141, a first magnetic element 142, and a first magnetic conductor 143. In other embodiments, the first driving mechanism 14 may not include the first magnetic conductor 143.

[0121] For example, the second drive mechanism 15 includes a second coil 151, a second magnetic element 152, and a second magnetic conductor 153. In other embodiments, the second drive mechanism 15 may not include the second magnetic conductor 153.

[0122] Exemplarily, the motor 10 also includes a circuit board assembly 17. The circuit board assembly 17 includes a motor circuit board 171, a driver chip 172, a first sensor 173, and a second sensor 174. The driver chip 172, the first sensor 173, and the second sensor 174 can all be fixed to and electrically connected to the motor circuit board 171. In other embodiments, the circuit board assembly 17 may not include the first sensor 173 and / or the second sensor 174. In other embodiments, the circuit board assembly 17 may also include more structures. Specifically, this application does not limit the scope.

[0123] For example, the motor 10 also includes a first magnetic member 181 and a second magnetic member 182. In other embodiments, the motor 10 may also exclude the first magnetic member 181 and / or the second magnetic member 182.

[0124] For example, the motor 10 also includes a heat sink 183. The heat sink 183 may be copper foil or other structures with heat dissipation function. In other embodiments, the motor 10 may not include the heat sink 183.

[0125] By way of example, the motor 10 also includes a housing 19. In other embodiments, the motor 10 may also exclude the housing 19.

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

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

[0128] In other embodiments, the base 11 may also exclude the third side 114 and the fourth side 115.

[0129] It is 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 112 and the second side 113 of the base 11 can be two independent structural components fixed to the bottom 111 of the base 11 by welding, bonding, or other methods.

[0130] For example, the bottom 111, first side 112, second side 113, third side 114 and fourth side 115 of the base 11 can 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. In one embodiment, the first groove 1121 and the second groove 1122 may be arranged along the Z-axis direction. The length extension direction of both the first groove 1121 and the second groove 1122 may be the X-axis direction.

[0132] For example, the second side 113 of the base 11 is provided with a third groove 1131 and a fourth groove 1132 spaced apart. In one embodiment, the length extension direction of both the third groove 1131 and the fourth groove 1132 can be the X-axis direction.

[0133] For example, the third side 114 of the base 11 is provided with a first through hole 1141. The first through hole 1141 communicates with the mounting space 116.

[0134] For example, the fourth side 115 of the base 11 is provided with a second through hole 1151. The second through hole 1151 communicates with the mounting space 116.

[0135] Figure 8 is a partial structural schematic diagram of some embodiments of the motor 10 shown in Figure 4.

[0136] As shown in Figure 8, the first coil 141 is fixed to the first side 112 of the base 11. At least a portion of the first coil 141 may be located within the mounting space 116.

[0137] As shown in Figure 8, the first connector 16a and the second connector 16b are fixed to the first side 112 of the base 11 at a distance. At least a portion of the first connector 16a may be located within the mounting space 116. At least a portion of the second connector 16b may be located within the mounting space 116.

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

[0139] As shown in Figures 6 and 8, exemplarily, the first connector 16a is fixed within the first groove 1121 of the base 11. A portion of the first connector 16a protrudes from the first groove 1121. The second connector 16b is fixed within the second groove 1122 of the base 11. A portion of the second connector 16b protrudes from the second groove 1122.

[0140] Figure 9 is a structural schematic diagram of part of the motor 10 shown in Figure 8 from another angle.

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

[0142] As shown in Figure 9, the third connector 16c and the fourth connector 16d are fixed to the second side 113 of the base 11 at a distance. At least a portion of the third connector 16c may be located within the mounting space 116. At least a portion of the fourth connector 16d may be located within the mounting space 116.

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

[0144] As shown in Figures 7 and 9, exemplarily, the third connector 16c is fixed within the third groove 1131 of the base 11. A portion of the third connector 16c protrudes relative to the third groove 1131. The fourth connector 16d is fixed within the fourth groove 1132 of the base 11. A portion of the fourth connector 16d protrudes relative to the fourth groove 1132.

[0145] Please refer to Figures 8 and 9, and in conjunction with Figure 5, as shown, the circuit board assembly 17 is fixed to the base 11 and can be located at least partially within the mounting space 116.

[0146] For example, 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, and a portion passes through the first side 112 and / or the second side 113 and is disposed outside the base 11. The drive chip 172, the first sensor 173, and the second sensor 174 may be disposed within the mounting space 116.

[0147] For example, the first coil 141 can be electrically connected to the motor circuit board 171 via a conductive element within the base 11, and then electrically connected to the driver chip 172 via the motor circuit board 171. The conductive element can be formed within the base 11 using an in-mold molding process. In other embodiments, the first coil 141 can be electrically connected to the motor circuit board 171 via a flexible circuit board or spring, and then electrically connected to the driver chip 172 via 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 it. It is understood that the driver chip 172 can control the current status of the first coil 141 (e.g., whether current flows or the magnitude of the current when current flows).

[0148] It is understandable that the way the second coil 151 is electrically connected to the driver chip 172 can be referred to as the way the first coil 141 is electrically connected to the driver chip 172. Specific details will not be repeated here. At this time, the driver chip 172 can also control the current status of the second coil 151 (e.g., whether current flows through it or the magnitude of the current when it flows through).

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

[0150] As shown in Figures 10 and 11, the first carrier 12 includes a first fixing part 121 and a second fixing part 122. It can be understood that although Figures 10 and 11 divide the first carrier 12 into two parts, it does not affect the fact that the first carrier 12 can be a one-piece structure.

[0151] For example, the first carrier 12 can be L-shaped, that is, the first fixing part 121 and the second fixing part 122 can form an L-shape.

[0152] For example, the first fixing part 121 is provided with a first mounting hole 1211.

[0153] For example, the second fixing part 122 is provided with a first mounting groove 1221.

[0154] For example, the second fixing part 122 is provided with a first sliding groove 1222 and a second sliding groove 1223 spaced apart. The first sliding groove 1222 and the second sliding groove 1223 can be located on both sides of the first mounting groove 1221, that is, the first mounting groove 1221 is located between the first sliding groove 1222 and the second sliding groove 1223. The extending direction of the first sliding groove 1222 and the second sliding groove 1223 can be the X-axis direction.

[0155] Figure 12 is a partially exploded schematic diagram of some embodiments of the first carrier 12 shown in Figure 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, forms a first mounting hole 1211. Exemplarily, the first cover plate 12b can be fixedly connected to the first main body 12a by means of bonding, welding, or other methods.

[0157] It is understandable that, since the first carrier 12 is assembled from the first main body 12a and the first cover plate 12b, when assembling the first carrier 12 with other structural components, the first main body 12a can be assembled with other structural components first, and then the first cover plate 12b can be fixed to the first main body 12a in order to fix the other structural components to the first carrier 12.

[0158] Figure 13 is a partial structural schematic diagram of some embodiments of the motor 10 shown in Figure 4.

[0159] Referring to Figure 13, and in conjunction with Figures 10 and 11, the first magnetic element 142 is fixed to the first carrier 12. Exemplarily, the first magnetic element 142 is located in the first mounting groove 1221.

[0160] It is understood that the first magnetic element 142 can be fixed to the first magnetic conductive element 143, and the first magnetic conductive element 143 is then fixed to the first carrier 12. In this case, the first magnetic element 142 can be fixed to the first carrier 12 through the first magnetic conductive element 143 (see Figure 5). Exemplarily, at least a portion of the first magnetic conductive element 143 can be embedded within the first carrier 12.

[0161] For example, the first magnetic element 142 may include one or more magnets, and the implementation structure of the first magnetic element 142 can be varied. For example, in some embodiments, the first magnetic element 142 is a Helbeck magnet array. In other embodiments, the first magnetic element 142 may employ a dual-magnet scheme, for example, consisting of two magnets arranged in the X-axis direction with opposite polarities. In still other embodiments, the first magnetic element 142 may employ a single-magnet scheme, for example, consisting of a single magnet comprising two parts with opposite polarities. The magnet can be manufactured using a bipolar magnetization process. It is understood that the polarity direction can be from the North Pole (N) to the South Pole (S), or from the South Pole (S) to the North Pole (N).

[0162] Figure 14 is a partial structural schematic diagram of some embodiments of the motor 10 shown in Figure 4. Figure 15 is a partial cross-sectional view of one embodiment of the motor 10 shown in Figure 14 at line BB.

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

[0164] For example, the second fixing part 122 of the first carrier 12 is slidably connected to the first side part 112 of the base 11 via the first connector 16a and the second connector 16b.

[0165] Understandably, when both the first connector 16a and the second connector 16b use a sliding shaft structure for guidance, the first carrier 12 will have line contact with the first connector 16a and the second connector 16b during movement. In this way, the contact area of ​​the first carrier 12 is larger, which can avoid the risk of dents caused by excessive impact pressure and improve the reliability of the motor 10.

[0166] In some embodiments, the fit between the first connector 16a, the second connector 16b, and the first carrier 12 includes both tight fit and loose fit to reduce assembly difficulty. For example, as shown in FIG15, the first groove 1222 of the first carrier 12 can be a "V" shaped groove. The second groove 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 wall of the first groove 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 wall of the second groove 1223 can contact the second connector 16b, achieving a loose fit. In other embodiments, the shapes of the first groove 1222 and the second groove 1223 of the first carrier 12 can be interchanged, that is, the first groove 1222 of the first carrier 12 can be an "L" shaped groove or a "U" shaped groove, and the second groove 1223 can be a "V" shaped groove.

[0167] In addition, the first carrier 12 can ensure the stable support of the first connector 16a and the second connector 16b by the cooperation of the "V" shaped groove and the "L" shaped groove, or the cooperation of the "V" shaped groove and the "U" shaped groove, thus ensuring the stability of the movement of the first carrier 12.

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

[0169] As shown in Figures 16A and 16B, exemplarily, 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 disposed facing the first magnetic element 142, and is used to drive the first carrier 12 to move relative to the base 11 along the X-axis. When the first carrier 12 moves relative to the base 11 along the X-axis, the first carrier 12 can drive the first lens 20 mounted thereon to move along the X-axis. Here, "the first coil 141 is disposed facing the first magnetic element 142" means that the winding plane of the first coil 141 faces the first magnetic element 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 element 142 and the first coil 141. The magnetic gap is not affected by the movement of the first carrier 12, thus avoiding the problem of rapid decrease in driving force caused by the increase of magnetic gap. This ensures that the driving force of the motor 10 is large and relatively stable, which is beneficial to the focusing function or the large stroke design of optical zoom of the motor 10.

[0171] The first magnetic element 142 may have two opposite polarity directions, and the polarity direction of the first magnetic element 142 is perpendicular to the winding plane of the first coil 141. The coils in two sections of the first coil 141 may be respectively arranged corresponding to the two polarity directions of the first magnetic element 142, and the current flows in opposite directions within the two sections of the coil. In this case, the side of the first magnetic element 142 facing the first coil 141 includes a north pole (N) and a south pole (S), and the side of the first magnetic element 142 facing away from the first coil 141 correspondingly includes a south pole (S) and a north pole (N).

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

[0173] As shown in Figure 17, the second carrier 13 includes a third fixing part 131 and a fourth fixing part 132. It can be 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 a one-piece structure.

[0174] For example, the second carrier 13 may be L-shaped.

[0175] For example, the third fixing part 131 is provided with a second mounting hole 1311.

[0176] For example, the fourth fixing part 132 is provided with a second mounting groove 1321.

[0177] For example, the fourth fixing part 132 is provided with a third sliding groove 1322 and a fourth sliding groove 1323 spaced apart. The third sliding groove 1322 and the fourth sliding groove 1323 can be located on both sides of the second mounting groove 1321, that is, the second mounting groove 1321 is located between the third sliding groove 1322 and the fourth sliding groove 1323. The extending direction of the third sliding groove 1322 and the fourth sliding groove 1323 can be the X-axis direction.

[0178] Figure 18 is a partially exploded schematic diagram of some embodiments of the second carrier 13 shown in Figure 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, forms a second mounting hole 1311. Exemplarily, the second cover plate 13b can be fixedly connected to the second main body 13a by means of bonding, welding, or other methods.

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

[0181] Figure 19 is a partial structural schematic diagram of some embodiments of the motor 10 shown in Figure 4.

[0182] Referring to Figure 19 and in conjunction with Figure 17, the second magnetic element 152 is fixed to the second carrier 13. Exemplarily, the second magnetic element 152 is located in the second mounting groove 1321.

[0183] It is understood that the second magnetic element 152 can be fixed to the second magnetic conductive element 153 (see Figure 5), and the second magnetic conductive element 153 (see Figure 5) is then fixed to the second carrier 13. In this case, the second magnetic element 152 can be fixed to the second carrier 13 via the second magnetic conductive element 153 (see Figure 5). Exemplarily, at least a portion of the second magnetic element 152 (see Figure 5) can be embedded within the first carrier 12.

[0184] For example, the second magnetic element 152 may include one or more magnets, and the implementation structure of the second magnetic element 152 can be varied. For instance, in some embodiments, the second magnetic element 152 may employ a dual-magnet scheme, such as consisting of two magnets arranged along the X-axis with opposite polarities. In other embodiments, the second magnetic element 152 is a Helbeck magnet array. In still other embodiments, the second magnetic element 152 may employ a single-magnet scheme, such as consisting of a single magnet comprising two parts with opposite polarities. This magnet may be manufactured using a bipolar magnetization process.

[0185] Figure 20 is a partial structural schematic diagram of some embodiments of the motor 10 shown in Figure 4. Figure 21 is a partial cross-sectional view of one embodiment of the motor 10 shown in Figure 20 at the DD line.

[0186] Please refer to Figures 20 and 21, and in conjunction with Figures 9 and 19, in some embodiments, at least a portion of the second carrier 13 may be located within the mounting 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 direction. 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 direction. Furthermore, the second fixing portion 122 of the first carrier 12 is disposed opposite to the first side portion 112 of the base 11. The fourth fixing portion 132 of the second carrier 13 is disposed opposite to the second side portion 113 of the base 11.

[0188] For example, the second fixing part 122 of the first carrier 12 is located between the third fixing part 131 of the second carrier 13 and the first side part 112 of the base 11. The fourth fixing part 132 of the second carrier 13 is located between the first fixing part 121 of the first carrier 12 and the second side part 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 is understood that the second fixing part 122 of the first carrier 12 being located between the third fixing part 131 of the second carrier 13 and the first side part 112 of the base 11 includes two situations: one is that during the movement of the first carrier 12 relative to the base 11, and / or during the movement of the second carrier 13 relative to the base 11, the second fixing part 122 of the first carrier 12 can always be located between the third fixing part 131 of the second carrier 13 and the first side part 112 of the base 11; the other is that during the movement of the first carrier 12 relative to the base 11, and / or during the movement of the second carrier 13 relative to the base 11, the second fixing part 122 of the first carrier 12 can be located between the third fixing part 131 of the second carrier 13 and the first side part 112 of the base 11 at a certain moment or for a certain period of time. Similarly, the explanation of the location of the fourth fixing part 132 of the second carrier 13 between the first fixing part 121 of the first carrier 12 and the second side part 113 of the base 11 can also refer to the explanation of the location of the second fixing part 122 of the first carrier 12 between the third fixing part 131 of the second carrier 13 and the first side part 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 defined.

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

[0192] Please refer to Figures 20 and 21, and in conjunction with Figures 9 and 19, as shown, the third groove 1322 of the second carrier 13 corresponds to the third groove 1131 of the base 11, and the fourth 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 located within the third groove 1322; a portion of the fourth connector 16d is located within the fourth groove 1323. The second carrier 13 is slidably connected to the base 11 via the third connector 16c and the fourth connector 16d, and the relative sliding direction of the two is parallel to the guiding direction of the third connector 16c and the fourth connector 16d, that is, the X-axis direction. When both the third connector 16c and the fourth connector 16d adopt a sliding shaft structure, the axial direction of the sliding shaft is the guiding direction of the third connector 16c and the fourth connector 16d; when both the third connector 16c and the fourth connector 16d adopt a ball bearing structure, the arrangement direction of the multiple balls is the guiding direction of the third connector 16c and the fourth connector 16d.

[0193] For example, the fourth fixing part 132 of the second carrier 13 is slidably connected to the second side part 113 of the base 11 via the third connector 16c and the fourth connector 16d.

[0194] Understandably, when both the third connector 16c and the fourth connector 16d use a sliding shaft structure for guidance, the second carrier 13 will be in line contact with the third connector 16c and the fourth connector 16d during movement. This results in a larger contact area for the second carrier 13, avoiding the risk of dents caused by excessive impact pressure and improving the reliability of the motor 10.

[0195] In some embodiments, the fit between the third connector 16c and the fourth connector 16d and the second carrier 13 includes both tight fit and loose fit to reduce assembly difficulty. For example, as shown in FIG21, the third groove 1322 of the second carrier 13 can be a "V" shaped groove. The fourth groove 1323 of the second carrier 13 can be an "L" shaped groove or a "U" shaped groove. When the "V" shaped groove fits with the third connector 16c, the side wall of the third groove 1322 can contact the third connector 16c, achieving a tight fit. When the "L" shaped groove or the "U" shaped groove fits with the fourth connector 16d, the bottom wall of the fourth groove 1323 can contact the fourth connector 16d, achieving a loose fit.

[0196] Furthermore, the second carrier 13 can ensure the stable support of the third connector 16c and the fourth connector 16d through the cooperation of the "V" shaped groove and the "L" shaped groove, or the cooperation of the "V" shaped groove and the "U" shaped groove, thus ensuring the stability of the movement of the second carrier 13.

[0197] Figure 22A is a partial structural schematic diagram of some embodiments of the lens assembly 101 shown in Figure 3. Figure 22B is a partial cross-sectional view of one embodiment of the lens assembly 101 shown in Figure 22A at line EE.

[0198] As shown in Figures 22A and 22B, exemplarily, 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 disposed facing the second magnetic element 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. Here, "the second coil 151 is disposed facing the second magnetic element 152" means that the winding plane of the second coil 151 faces the second magnetic element 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 element 152 and the second coil 151. The magnetic gap is not affected by the movement of the second carrier 13, thus avoiding the problem of rapid decrease in driving force caused by the increase of magnetic gap. This ensures that the driving force of the motor 10 is large and relatively stable, which is beneficial to the focusing function or the large stroke design of optical zoom of the motor 10.

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

[0201] Understandably, in this embodiment, the first magnetic element 142 is disposed near the first side 112 of the base 11, and the second magnetic element 152 is disposed near the second side 113 of the base 11. The first magnetic element 142 and the second magnetic element 152 can be located on opposite sides of the first lens 20 and the second lens 30. In this way, magnetic interference between the first magnetic element 142 and the second magnetic element 152 is less likely to occur during the movement of the first lens 20 and the second lens 30.

[0202] The preceding text, with reference to the accompanying drawings, details the specific structures and connection methods of the base 11, the first carrier 12, and the second carrier 13. It is understood that in this embodiment, the first carrier 12 can be slidably connected to the base 11 via the first connector 16a and the second connector 16b. In this case, the first carrier 12 can drive the first lens 20 mounted thereon to move along the X-axis. The second carrier 13 can be slidably connected to the base 11 via the third connector 16c and the fourth connector 16d. The second carrier 13 can drive the second lens 30 mounted thereon to move along the X-axis. Thus, the movement of the first lens 20 and the second lens 30 along the X-axis enables focusing and continuous optical zoom of the camera module 100.

[0203] Furthermore, in this embodiment, the first carrier 12 is connected to the first side 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 113 of the base 11 via the third connector 16c and the fourth connector 16d, thereby achieving a guiding scheme where the two sides of the motor 10 guide the first carrier 12 and the second carrier 13 respectively. Exemplarily, the first connector 16a, the second connector 16b, the third connector 16c, and the fourth connector 16d all adopt a sliding shaft method. In this case, the camera module 100 can achieve a guiding scheme where the two sides of the motor 10 guide the first carrier 12 and the second carrier 13 respectively.

[0204] Understandably, in one embodiment, the first carrier 12 is connected to the bottom 111 of the base 11 via a first connector 16a and a second connector 16b, and the second carrier 13 is connected to the bottom 111 of the base 11 via a third connector 16c and a fourth connector 16d. In this embodiment, to ensure the connection stability between the first carrier 12 and the base 11, the first connector 16a and the second connector 16b need to be located on both sides of the first lens 20. In this case, the distance between the first connector 16a and the second connector 16b will inevitably increase significantly, and the connection stability between the first carrier 12 and the base 11 will still be poor. If the connection stability between the first carrier 12 and the base 11 is improved by increasing the magnetic force between the magnetic attractor and the magnetic component, the size of the magnetic attractor and the magnetic component will inevitably increase. This will also significantly increase the size of the motor 10, which is not conducive to achieving a miniaturized motor 10. In this embodiment, the first carrier 12 is connected to the first side 112 of the base 11 via a first connector 16a and a second connector 16b, meaning the first connector 16a and the second connector 16b are located on the side of the base 11. This ensures the stability of the connection between the first carrier 12 and the base 11, while the first connector 16a and the second connector 16b are not constrained by the first lens 20. Therefore, the distance between the first connector 16a and the second connector 16b can be set smaller, which is beneficial for miniaturizing the motor 10. Similarly, the third connector 16c and the fourth connector 16d are arranged in the same way, achieving the same technical effect. Further details are omitted here.

[0205] Understandably, in one embodiment, the first carrier 12 is connected to the bottom 111 of the base 11 via a first connector 16a and a second connector 16b, and the second carrier 13 is connected to the bottom 111 of the base 11 via a third connector 16c and a 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 laid flat on the XY plane, they occupy a large amount of space in the XY plane, resulting in a non-compact arrangement of the motor 10 and hindering its miniaturization. In this embodiment, the first carrier 12 is connected to the first side 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 113 of the base 11 via the third connector 16c and the fourth connector 16d. The first connector 16a and the second connector 16b are arranged at intervals along the Z-axis, and 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 relatively little space in the XY plane, resulting in a more compact structural arrangement of the motor 10, which is beneficial for miniaturizing the motor 10.

[0206] Understandably, 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 prone to jamming due to the non-parallel guidance of the first connector 16a, the second connector 16b, the third connector 16c, and the fourth connector 16d. However, 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 jam during movement.

[0207] In this embodiment, the first carrier 12 is slidably connected to the base 11 via a first connector 16a and a second connector 16b, and the second carrier 13 is slidably connected to the base 11 via a third connector 16c and a fourth connector 16d. The first connector 16a and the second connector 16b are positioned near the first side 112 of the base 11, and the third connector 16c and the fourth connector 16d are positioned near the second side 113 of the base 11. In this configuration, the connection positions of the first carrier 12 and the base 11, and the connection positions of the second carrier 13 and the base 11, are located on different sides of the base 11. This minimizes the interference between the connection positions of the first carrier 12 and the base 11, and the connection positions of the second carrier 13 and the base 11.

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

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

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

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

[0212] For example, the second side 113 of the base 11 is provided with a second fixing groove 1133. The second magnetic member 182 is disposed in the second fixing groove 1133.

[0213] Figure 25 is a partially exploded view of some embodiments of the lens assembly 101 shown in Figure 3. Figure 26 is a partially exploded view of the lens assembly 101 shown in Figure 25 from another angle.

[0214] As shown in Figures 25 and 26, exemplarily, the dimension L1 of the first magnetic chuck 181 in the X-axis direction is greater than the sum of the dimension L2 of the first magnetic component 142 in the X-axis direction and the travel distance L3 of the first carrier 12 in the X-axis direction, i.e., L1 > L2 + L3. The first magnetic chuck 181 protrudes from both sides of the first magnetic component 142 in the X-axis direction. During the focusing or optical zooming process of the motor 10, the first magnetic chuck 181 and the first magnetic component 142 can still maintain a direct or nearly direct alignment, thereby ensuring the stability of the magnetic attraction force. Specifically, the projection of the first magnetic chuck 181 on the XZ plane covers the projection of the first magnetic component 142 on the XZ plane in the X-axis direction, which can be considered as a direct alignment between the two.

[0215] It is understandable that by setting the dimension L1 of the first magnetic element 181 in the X-axis direction to be greater than the sum of the dimension L2 of the first magnetic element 142 in the X-axis direction and the movement stroke L3 of the first carrier 12 in the X-axis direction, it is beneficial to minimize the magnetic return force and to achieve self-locking at any position within the movement stroke of the first carrier 12 in the X-axis direction. In other words, this embodiment can enable the first carrier 12 to remain stationary at the current target position when it is powered off (the first coil 141 is not energized). That is, when the first carrier 12 is at the target position, it is not necessary to continuously energize the first coil 141 to maintain the current position, thereby reducing power consumption.

[0216] As shown in Figures 25 and 26, exemplarily, the dimension H1 of the second magnetic chuck 182 in the X-axis direction is greater than the sum of the dimension H2 of the second magnetic component 152 in the X-axis direction and the travel distance H3 of the second carrier 13 in the X-axis direction, i.e., H1 > H2 + H3. The second magnetic chuck 182 protrudes from both sides of the second magnetic component 152 in the X-axis direction. During the focusing or optical zooming process of the motor 10, the second magnetic chuck 182 and the second magnetic component 152 can still maintain a positive or nearly positive relationship, thereby ensuring the stability of the magnetic attraction force. Specifically, the projection of the second magnetic chuck 182 on the XZ plane covers the projection of the second magnetic component 152 on the XZ plane in the X-axis direction, which can be considered as a positive relationship between the two.

[0217] It is understandable that by setting the dimension H1 of the second magnetic element 182 in the X-axis direction to be greater than the sum of the dimension H2 of the second magnetic element 152 in the X-axis direction and the movement stroke H3 of the second carrier 13 in the X-axis direction, it is beneficial to minimize the magnetic return force and to achieve self-locking at any position within the movement stroke of the second carrier 13 in the X-axis direction. In other words, this embodiment can enable the second carrier 13 to remain stationary at the current target position when it is powered off (the second coil 151 is not energized). That is, when the second carrier 13 is at the target position, it is not necessary to continuously energize the second coil 151 to maintain the current position, thereby reducing power consumption.

[0218] It is understood 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 embodiments of this application do not strictly limit this.

[0219] Understandably, the above description illustrates how a first magnetic element 181 is fixed to the first side 112 of the base 11, and how the magnetic force between the first magnetic element 181 and the first magnetic element 142 enables the first carrier 12 to be pre-tightened to the first side 112 of the base 11. The following section will further describe, in conjunction with the relevant accompanying drawings, a method for achieving pre-tightening between the first carrier 12 and the first side 112 of the base 11.

[0220] As shown in Figures 24 to 26, the first connector 16a adopts a sliding shaft structure. The first connector 16a is made of magnetically conductive materials, such as silicon steel sheets and alloys formed from various iron products and rare earth elements.

[0221] Understandably, the magnetic force between the first connector 16a and the first magnetic element 142 causes the first carrier 12 to tend to approach the first side 112 of the base 11, thereby ensuring that the first side 112 of the base 11, the first connector 16a, the second connector 16b and the first carrier 12 remain in contact to achieve pre-tightening.

[0222] In one embodiment, the relative permeability of the first connector 16a can be greater than or equal to 1.1. This results in a larger magnetic force between the first connector 16a and the first magnetic element 142, which is beneficial for improving the pre-tightening capability between the first carrier 12 and the first side portion 112 of the base 11.

[0223] In one embodiment, the dimension of the first connector 16a in the X-axis direction is greater than the sum of the dimension of the first magnetic component 142 in the X-axis direction and the travel distance of the first carrier 12 in the X-axis direction. This is beneficial for minimizing the magnetic return force and for enabling self-locking at any position within the travel distance 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 it is powered off (without energizing the first coil 141). That is, when the first carrier 12 is at the target position, it is not necessary to continuously energize the first coil 141 to maintain the current position, thereby reducing power consumption.

[0224] Understandably, the second connector 16b adopts a sliding shaft structure. The second connector 16b can also be made of a magnetic material. The magnetic force between the second connector 16b and the first magnetic element 142 can further cause the first carrier 12 to tend to approach the first side 112 of the base 11, thereby further ensuring that the first side 112 of the base 11, the first connector 16a, the second connector 16b and the first carrier 12 maintain contact and achieve pre-tightening.

[0225] In one embodiment, the relative permeability of the second connector 16b can be greater than or equal to 1.1. This results in a larger magnetic force between the second connector 16b and the first magnetic element 142, which is beneficial for improving the pre-tightening capability between the first carrier 12 and the first side portion 112 of the base 11.

[0226] In one embodiment, the dimension of the second connector 16b in the X-axis direction is greater than the sum of the dimension of the first magnetic element 142 in the X-axis direction and the travel distance of the first carrier 12 in the X-axis direction.

[0227] As shown in Figures 24 to 26, the third connector 16c adopts a sliding shaft structure. The third connector 16c can also be made of a magnetically conductive material. Specifically, the arrangement of the third connector 16c can be referred to the arrangement of the first connector 16a. It will not be repeated here. Additionally, the fourth connector 16d adopts a sliding shaft structure. The fourth connector 16d can also be made of a magnetically conductive material. Specifically, the arrangement of the fourth connector 16d can be referred to the arrangement of the second connector 16b. It will not be repeated here.

[0228] Figure 27 is a partially exploded view of some embodiments of the lens assembly 101 shown in Figure 3. Figure 28 is a partial cross-sectional view of another embodiment of the lens assembly 101 shown in Figure 3 at the FF line.

[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 via a motor circuit board 171. The first sensor 173 can be soldered to a first pad to achieve structural fixation and electrical connection. The first sensor 173 can be used to detect the positional 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 uses 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 grating 184. The first magnetic grating 184 is fixed to the first carrier 12. Exemplarily, the length direction of the first magnetic grating 184 may be parallel to the direction of movement of the first carrier 12 (i.e., the X-axis direction). Exemplarily, the first magnetic grating 184 may be fixed to the second fixing part 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 grating 184 during the movement of the first carrier 12, and to detect the position change of the first carrier 12 in the X-axis direction by means of the magnetic difference.

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

[0233] Figure 29 is a partial cross-sectional view of the lens assembly 101 shown in Figure 3 at the GG line in some embodiments.

[0234] As shown in Figures 27 and 29, in some embodiments, the second sensor 174 is fixed to the bottom 111 of the base 11 via a 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 positional changes of the second carrier 13 in the X-axis direction. The second sensor 174 can be a Hall sensor or a tunneling 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 grating 185. The second magnetic grating 185 is fixed to the second carrier 13. Exemplarily, the length direction of the second magnetic grating 185 may be parallel to the direction of movement of the second carrier 13 (i.e., the X-axis direction). Exemplarily, the second magnetic grating 185 may be fixed to the fourth fixing part 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 grating 185 during the movement of the second carrier 13, and to detect the position change of the second carrier 13 in the X-axis direction by means of the magnetic difference.

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

[0238] Figure 30 is a partially exploded view of some embodiments of the lens assembly 101 shown in Figure 3. Figure 31 is a partial cross-sectional view of one embodiment of the lens assembly 101 shown in Figure 3 at line HH.

[0239] As shown in Figures 30 and 31, in some embodiments, the housing 19 includes a top plate 191 and a side frame 192. The side frame 192 is 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 with the base 11, and the housing 19 covers 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 together cover the first side 112, the second side 113, the third side 114, and the fourth side 115 of the base 11. The housing 19 and the base 11 cooperate to 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 part of the circuit board assembly 17.

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

[0242] In one embodiment, the top plate 191 of the housing 19 may also be fixed to the first side 112, the second side 113, the third side 114, and the fourth side 115 of the base 11. Exemplarily, the top plate 191 of the housing 19 may be fixed to the first side 112, the second side 113, the third side 114, and the fourth side 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 112, the second side 113, the third side 114, and the fourth side 115 of the base 11. Exemplarily, the side frame 192 of the housing 19 may be fixed to the first side 112, the second side 113, the third side 114, and the fourth side 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 to each other. The base plate 1831 connects 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 space for the motor circuit board 171 extending to the outside of the base 11.

[0245] It is understood that the heat sink 183 may include more or fewer structures. For example, the heat sink 183 may include fewer structures. Exemplarily, the heat sink 183 may also exclude the first side plate 1832 and / or the second side plate 1833. As another example, the heat sink 183 may include more structures. Exemplarily, the heat sink 183 includes a third side plate (not shown) and a fourth side plate (not shown) disposed opposite each other. The third side plate (not shown) and the fourth side plate (not shown) connect to the base 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 the heat sink 183 is fixed to the bottom 111 of the base 11 on the side away from the motor circuit board 171. The heat sink 183 can be used to dissipate the heat generated by the driver chip 172, thereby preventing excessively high local temperatures inside the motor 10, which could lead to poor spatial frequency response (SFR) of the first lens 20 and / or the second lens 30. In other words, the heat sink 183 can be used to dissipate heat from the driver chip 172.

[0247] Exemplarily, the base plate 1831 of the heat sink 183 is fixed to the 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 the 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 the 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 the embodiments of this application do not strictly limit this.

[0248] Figure 32 is a partially exploded view of some embodiments of the motor 10 shown in Figure 4.

[0249] As shown in Figure 32, in some embodiments, both the first connector 16a and the second connector 16b adopt a sliding shaft structure.

[0250] As shown in Figure 32, 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 Figure 32) and a second contact position M2 (the area enclosed by the dashed line in Figure 32). 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 Figure 32). The third contact position M3 is directly opposite the space between the first contact position M1 and the second contact position M2.

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

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

[0253] It is understandable that the contact method between the second carrier 13 and the third connector 16c and the fourth connector 16d can be referred to the contact method between the first carrier 12 and the first connector 16a and the second connector 16b. Specific details will not be elaborated here.

[0254] Understandably, the above text, in conjunction with the accompanying drawings, describes several structures of the motor 10. The following text will introduce several more structures of the motor 10.

[0255] For example, in the various embodiments described above, the first coil 141 is fixed to the first side 112 of the base 11. The first magnetic element 142 is fixed to the first carrier 12. In other embodiments, the positions of the first coil 141 and the first magnetic element 142 can be interchanged, that is, the first magnetic element 142 is fixed to the first side 112 of the base 11, and the first coil 141 is fixed to the first carrier 12. This application does not specifically limit the details.

[0256] For example, in the various embodiments described above, the second coil 151 is fixed to the second side 113 of the base 11. The second magnetic element 152 is fixed to the second carrier 13. In other embodiments, the positions of the second coil 151 and the second magnetic element 152 can be interchanged, that is, the second magnetic element 152 is fixed to the first side 112 of the base 11. The second coil 151 is fixed to the first carrier 12. This application does not specifically limit the details.

[0257] For example, in the various embodiments described above, 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 also include more carriers. For example, the motor 10 may also include a third carrier (not shown), a fourth carrier (not shown), ..., a Pth carrier (not shown), where P is an integer greater than 2. The third carrier (not shown), the fourth carrier (not shown), ..., the Pth carrier (not shown) are all used to support lenses, thereby enabling the movement of multiple lenses. Furthermore, the third carrier (not shown), the fourth carrier (not shown), ..., the Pth carrier (not shown) are also each independently slidably connected to different positions of the base 11. The connection methods of the third carrier (not shown), the fourth carrier (not shown), ..., the Pth carrier (not shown) to the base 11 can be referred to the connection methods of the first carrier 12, the second carrier 13, and the base 11. Specific details will not be elaborated here. It is understood that the third carrier (not shown), the fourth carrier (not shown), ..., the Pth carrier (not shown) cooperate with the first carrier 12 and the second carrier 13 to achieve focusing and optical zoom of the camera module 100. Specific details are not limited in this application.

[0258] For example, in other embodiments, the first connector 16a and the second connector 16b may also be fixed to the first carrier 12. The first connector 16a and the second connector 16b are slidably connected to the base 11. In other embodiments, the third connector 16c and the fourth connector 16d may also be fixed to the second carrier 13. The third connector 16c and the fourth connector 16d are slidably connected to the base 11. Specific details are not limited in this application.

[0259] For example, in other embodiments, the positions of the first sensor 173 and the first magnetic grating 184 can also be interchanged. In other words, the first sensor 173 is fixed to the first carrier 12, and the first magnetic grating 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 grating 185 can also be interchanged. In other words, the second sensor 174 is fixed to the second carrier 13, and the second magnetic grating 185 is fixed to the bottom 111 of the base 11. This application does not specifically limit the details.

That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application. The above are merely some embodiments and implementation methods of this application, and the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
