Description
Motors, camera modules and electronic equipment
[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on February 15, 2023, with application number 202310152040.7, and priority to the Chinese patent application with the invention name "Motor, camera module and electronic device", all contents of which are incorporated by reference into this application. Technical Field
[0002] The present application relates to the field of camera technology, and in particular to a motor, a camera module, and an electronic device. Background Art
[0003] With the popularity and development of smartphones, mobile photography has become a common photography method. Furthermore, phones with both optical image stabilization and autofocus are increasingly popular. Traditional camera modules include an image stabilization motor and a focus motor. The image stabilization motor is located inside the focus motor. When the camera module needs to focus, the focus motor drives the image stabilization motor, lens, and iris diaphragm along the optical axis. This makes the actuator, composed of the focus motor, image stabilization motor, lens, and iris diaphragm, heavy and prone to tipping, resulting in poor reliability.
[0004] Summary of the Invention
[0005] The embodiments of the present application provide a motor, a camera module including the motor, and an electronic device including the camera module, aiming to obtain a motor and a camera module whose mover is not easy to overturn and has better reliability.
[0006] In a first aspect, a motor is provided. The motor includes a base, an anti-shake carrier, a focus carrier, an anti-shake drive mechanism, and a focus drive mechanism; the anti-shake carrier is movably connected to the base, the focus carrier is located inside the anti-shake carrier, the focus carrier is movably connected to the anti-shake carrier, and the focus carrier is used to mount a lens; the anti-shake drive mechanism is used to drive the anti-shake carrier and the focus carrier to move relative to the base in a first direction and / or a second direction, and the focus drive mechanism is used to drive the focus carrier to move relative to the anti-shake carrier in a third direction, where the first direction intersects the second direction and is perpendicular to the first and second directions.
[0007] It is understandable that in some solutions, the anti-shake carrier is located on the inner side of the focus carrier. At this time, when the camera module needs to focus, the focus carrier needs to drive the anti-shake carrier, lens and variable aperture to move along the optical axis. In this way, the weight of the mover composed of the focus carrier, anti-shake carrier, lens and variable aperture is heavy, which causes the focus drive mechanism to increase the driving force by increasing the volume. Therefore, this setting is not conducive to the lightweight and miniaturized design of the motor. In this embodiment, the focus carrier is set on the inner side of the anti-shake carrier. At this time, when the camera module needs to focus, the focus carrier needs to drive the lens and variable aperture to move along the Z-axis direction. In this way, the mover in the focusing process of this embodiment can omit the anti-shake carrier, that is, the weight of the mover composed of the focus carrier, lens and variable aperture is lighter, which is conducive to the miniaturization of the focus drive mechanism. The motor of this embodiment can achieve a lightweight and miniaturized setting.
[0008] In addition, in this embodiment, the distance between the connection position between the focus carrier and the anti-shake carrier and the center of gravity of the mover formed by the focus carrier, the lens and the variable aperture is relatively close, which is beneficial to reducing the risk of the mover overturning.
[0009] It can be understood that, compared to the solution in which the anti-shake carrier is on the inner side of the focusing carrier, the anti-shake carrier requires at least two anti-shake drive mechanisms to push the anti-shake carrier to move in a plane perpendicular to the optical axis. In this way, the motor needs to arrange at least two sets of lines to provide signals and power to the anti-shake drive mechanism. And at least two sets of lines need to pass through the focusing carrier. Therefore, the power-on setting of this solution is relatively complicated, which increases the difficulty of setting up the motor. However, in this embodiment, by setting the focusing carrier on the inner side of the anti-shake carrier, since the focusing carrier requires a set of focusing drive mechanisms to push the focusing carrier to move along the optical axis, the motor also needs a set of lines to provide signals and power to the focusing drive mechanism, that is, the number of sets of lines passing through the anti-shake carrier is relatively small. Therefore, the power-on scheme of the solution of this embodiment is relatively simple, which can greatly reduce the difficulty of setting up the motor.
[0010] Furthermore, by placing the focus carrier inside the anti-shake carrier, the focus coil and focus magnet can be arranged closer to the lens. This allows them to partially protrude from the top surface of the motor when arranged vertically. It's understood that this protrusion can be placed inside the camera trim to maximize space utilization.
[0011] In a possible implementation, the anti-shake carrier is frame-shaped and is arranged around the focusing carrier.
[0012] In one possible implementation, the focus drive mechanism includes a focus coil and a focus magnetic component. The focus coil is arranged on the anti-shake carrier, the focus magnetic component is arranged on the focus carrier, and the focus coil faces the focus magnetic component.
[0013] In one possible implementation, the anti-shake carrier is provided with a through hole, which passes through the outer side and inner side of the anti-shake carrier; the motor includes a focusing circuit board, the focusing circuit board is fixed on the outer side of the anti-shake carrier, and the focusing coil is fixed on the focusing circuit board and is at least partially located in the through hole.
[0014] It can be understood that by disposing at least a portion of the focus coil in the through hole of the anti-shake carrier, the structural space of the anti-shake carrier can be utilized to a greater extent, thereby facilitating the miniaturization of the motor.
[0015] In one possible implementation, the motor further includes a first focusing magnetic conductive component, which is fixed on a side of the focusing circuit board away from the focusing coil, and the first focusing magnetic conductive component is arranged opposite to the focusing magnetic component.
[0016] It is understood that because the first focusing magnetic conductive member is fixed to the anti-shake carrier via the focusing circuit board, and the focusing magnetic member is fixed to the focusing carrier, when the first focusing magnetic conductive member and the focusing magnetic member generate a magnetic attraction, the focusing carrier and the anti-shake carrier are more tightly coupled under the action of the magnetic attraction. This further limits the focus carrier in certain directions on a plane perpendicular to the optical axis, thereby preventing the focus carrier from moving or shaking in these directions, thereby ensuring the stability of the focus carrier.
[0017] In one possible implementation, the motor further includes a second focus magnetic permeable member and a third focus magnetic permeable member, wherein the second focus magnetic permeable member and the third focus magnetic permeable member are both fixed to the first focus magnetic permeable member, and the second focus magnetic permeable member and the third focus magnetic permeable member both protrude relative to a front surface of the first focus magnetic permeable member, and the front surface of the first focus magnetic permeable member faces the focus circuit board;
[0018] The center of the focusing magnetic component is located between the center of the second focusing magnetic conductive component and the center of the third focusing magnetic conductive component.
[0019] It is understood that when the focusing magnetic member moves along the positive direction of the Z axis, the magnetic attraction between the first focusing magnetic member and the focusing magnetic member can cause the focusing magnetic member to generate a first restoring force along the negative direction of the Z axis, and the magnetic attraction between the second focusing magnetic member and the focusing magnetic member can cause the focusing magnetic member to generate a second restoring force along the positive direction of the Z axis. In this way, the first restoring force and the second restoring force can be roughly offset or completely offset. At this time, the stability of the focusing carrier during movement along the positive direction of the Z axis is better.
[0020] When the focusing magnetic member moves along the negative direction of the Z axis, it moves from the first position to the third position. The magnetic attraction between the first focusing magnetic member and the focusing magnetic member can cause the focusing magnetic member to generate a third restoring force along the positive direction of the Z axis. The magnetic attraction between the third focusing magnetic member and the focusing magnetic member can cause the focusing magnetic member to generate a fourth restoring force along the negative direction of the Z axis. In this way, the third restoring force and the fourth restoring force can be roughly offset or completely offset. At this time, the stability of the focusing carrier during movement along the Z axis is improved.
[0021] In a possible implementation, the focus carrier is slidably connected to the anti-shake carrier via a first sliding shaft and a second sliding shaft.
[0022] It can be understood that, compared to solutions where the focus carrier is connected to the anti-shake carrier via ball bearings, the focus carrier and the anti-shake carrier in this embodiment can achieve surface contact. This ensures better stability when the focus carrier slides relative to the anti-shake carrier along the Z-axis. Furthermore, due to the large contact area between the focus carrier and the anti-shake carrier, when pressure is applied to the focus carrier or the anti-shake carrier in the XY plane, the focus carrier or the anti-shake carrier is less likely to deform due to the high pressure, thereby greatly improving the reliability of the motor.
[0023] In one possible implementation, the contact position between the focus carrier and the first sliding shaft includes a first contact position and a second contact position, and the contact position between the focus carrier and the second sliding shaft includes a third contact position, and the second contact position is arranged closer to the bottom surface of the base relative to the third contact position;
[0024] Relative to the second sliding shaft, the first focusing magnetic conductive component is arranged close to the first sliding shaft.
[0025] It can be understood that by setting the focusing magnetic conductive part close to the first sliding axis, the center position of the magnetic attraction force generated by the focusing magnetic conductive part and the focusing magnetic part is set close to the first sliding axis. In this way, no matter whether the focusing carrier flips with the first flip axis as the axis or flips with the second flip axis as the axis, the vertical distance between the center position of the magnetic attraction force and the flip axis (that is, the lever arm of the magnetic attraction force) will become longer, and the torque of the magnetic attraction force will increase. Among them, the torque of the magnetic attraction force is equal to the product of the magnitude of the magnetic attraction force and the lever arm of the magnetic attraction force. Due to the increase in the torque of the magnetic attraction force, the ability of the focusing carrier to resist the flipping of gravity is increased, that is, the stability of the focusing carrier in the movement along the Z-axis direction is better. Among them, the first flip axis is the line between the bottom boundary line of the second contact position and the bottom boundary line of the third contact position. The second flip axis is the line between the top boundary line of the first contact position and the top boundary line of the third contact position.
[0026] In one possible implementation, the motor also includes a first reinforcement plate and a second reinforcement plate, and the first reinforcement plate and the second reinforcement plate are respectively spliced on both sides of the first focusing magnetic conductive component; the first reinforcement plate and the second reinforcement plate are both fixed on the side of the focusing circuit board away from the focusing coil.
[0027] It can be understood that the first reinforcement plate and the second reinforcement plate can be used to improve the structural strength of the focusing magnetic conductive component.
[0028] In one possible implementation, it is characterized in that the motor includes a focus driver chip, which is fixed on a focus circuit board; the motor includes multiple wiring terminals and multiple conductive springs, the multiple wiring terminals are fixed on the base at intervals, and the multiple conductive springs are fixed on the anti-shake carrier at intervals; the input ends of the multiple conductive springs are electrically connected to the multiple ports of the focus driver chip through the focus circuit board one by one, and the output ends of the multiple conductive springs are electrically connected to the multiple wiring terminals one by one.
[0029] It will be appreciated that in this embodiment, since the anti-shake carrier can move relative to the base in any direction in the XY plane, the distance between the anti-shake carrier and the base will change during the anti-shake process. Therefore, this embodiment provides a conductive spring with elastic force to connect the base's terminal block and the focus circuit board of the anti-shake carrier. When the distance between the anti-shake carrier and the base changes, the stretching of the conductive spring offsets this distance change, ensuring that the circuit is less likely to disconnect, thereby improving circuit stability.
[0030] In one possible implementation, the motor includes multiple wires, which are embedded in the anti-shake carrier at intervals, and the input end and output end of each wire are exposed relative to the anti-shake carrier; the input ends of multiple conductive springs are electrically connected to the output ends of the multiple wires one by one, and the output ends of the multiple wires are electrically connected to multiple ports of the focus driver chip one by one through the focus circuit board.
[0031] It is understood that the multiple conductive springs can be electrically connected to the multiple ports of the focus driver chip via the output ends of multiple wires, each corresponding to the other. These wires are embedded in the anti-shake carrier at intervals. This allows a portion of the wiring electrically connecting the terminals to the focus driver chip to be embedded within the anti-shake carrier, simplifying the wiring outside the anti-shake carrier.
[0032] In one possible implementation, the motor includes a plurality of conductive springs, which are fixed at intervals on a focusing carrier; the output ends of the plurality of conductive springs are electrically connected to a plurality of conductive springs in a one-to-one correspondence, and the input ends of the plurality of conductive springs are used to electrically connect to a plurality of ports of a variable aperture driver chip in a one-to-one correspondence.
[0033] It will be appreciated that in this embodiment, since the focus carrier can move relative to the anti-shake carrier in the Z-axis direction, the distance between the focus carrier and the anti-shake carrier will change during the focusing process. Therefore, this embodiment provides a conductive spring with elastic force to connect the variable aperture of the focus carrier and the conductive spring of the anti-shake carrier. When the distance between the focus carrier and the anti-shake carrier changes, the stretching of the conductive spring offsets this distance change, ensuring that the circuit is unlikely to disconnect, thereby improving circuit stability.
[0034] In one possible implementation, it is characterized in that the motor includes a focus driving chip, which is fixed on a focus circuit board; the motor includes a first flexible circuit board, and multiple ports of the focus driving chip are electrically connected to the first flexible circuit board through the focus circuit board.
[0035] It will be appreciated that in this embodiment, since the anti-shake carrier can move relative to the base in any direction in the XY plane, the distance between the anti-shake carrier and the base will change during the anti-shake process. Therefore, this embodiment provides a bendable first flexible circuit board to connect the base and the focus circuit board of the anti-shake carrier. When the distance between the anti-shake carrier and the base changes, the bendability of the first flexible circuit board offsets this distance change, ensuring that the circuit is less likely to break, thereby improving circuit stability.
[0036] In a possible implementation, the motor further includes a second flexible circuit board, and the second flexible circuit board is used to electrically connect the multiple ports of the variable aperture driving chip to the first flexible circuit board in a one-to-one correspondence through the focusing circuit board.
[0037] It will be appreciated that in this embodiment, since the focus carrier can move relative to the anti-shake carrier in the Z-axis direction, the distance between the focus carrier and the anti-shake carrier will change during the focusing process. Therefore, this embodiment provides a second flexible circuit board with a bendable structure to connect the variable aperture of the focus carrier and the second flexible circuit board of the anti-shake carrier. When the distance between the focus carrier and the anti-shake carrier changes, the bendability of the second flexible circuit board can offset this distance change, ensuring that the circuit is less likely to break, thereby improving circuit stability.
[0038] In one possible implementation, the second flexible circuit board includes a first section, a second section, and a third section, the second section is connected between the first section and the third section, the first section and the third section are arranged opposite to each other, and the second section is bent; the first section is used to electrically connect to multiple ports of the variable aperture driving chip, and the third section is electrically connected to the first flexible circuit board through the focusing circuit board.
[0039] It can be understood that by folding the second flexible circuit board up and down, any changes in the distance between the focus carrier and the anti-shake carrier are offset by the folded state of the second flexible circuit board, ensuring that the circuit is less likely to break, thereby improving circuit stability. Furthermore, this can also achieve minimal reaction force from the movement of the second flexible circuit board.
[0040] In a possible implementation, the focusing circuit board, the first flexible circuit board, and the second flexible circuit board are an integrally formed structure.
[0041] In one possible implementation, the anti-shake carrier includes a first side portion and a third side portion that are oppositely arranged, and a second side portion and a fourth side portion that are oppositely arranged, wherein the second side portion and the fourth side portion are connected between the first side portion and the third side portion;
[0042] The anti-shake drive mechanism includes a first anti-shake coil, a first anti-shake magnetic component, a second anti-shake coil, and a second anti-shake magnetic component, wherein the first anti-shake coil is fixed to the base, the first anti-shake magnetic component is fixed to the first edge portion, and the first anti-shake coil faces the first anti-shake magnetic component, and is used to drive the anti-shake carrier and the focus carrier to move in a first direction relative to the base; the second anti-shake coil is fixed to the base, the second anti-shake magnetic component is fixed to the second edge portion, and the second anti-shake coil faces the second anti-shake magnetic component, and is used to drive the anti-shake carrier and the focus carrier to move in a second direction relative to the base;
[0043] The focusing coil is fixed on the third side portion, and a portion of the first flexible circuit board is located between the fourth side portion and the base.
[0044] It is understandable that by locating a portion of the first flexible circuit board between the fourth side of the anti-shake carrier and the base, the first flexible circuit board is located in a non-magnetic space, thereby reducing the impact on the magnetic components on the motor.
[0045] In a second aspect, a camera module is provided, which includes a lens, an image sensor, and the above-described motor, wherein the lens is mounted on a focus carrier, and the image sensor is located on the light-emitting side of the lens.
[0046] In one possible implementation, the camera module also includes a variable aperture, which is located on the light-entering side of the lens.
[0047] In a third aspect, an electronic device is provided, which includes a device housing and the aforementioned camera module, wherein the camera module is disposed in the device housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.
[0078] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after the connection remains unchanged. "Sliding connection" means that the two are connected to each other and can slide relative to each other after the connection. The directional terms mentioned in the embodiments of the present application, such as "up", "down", "left", "right", "inside", "outside", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. "Multiple" means at least two. A and / or B include three schemes, specifically Scheme A, Scheme B and Scheme AB.
[0079] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.
[0080] In addition, in the embodiments of the present application, the mathematical concepts mentioned, such as parallel and perpendicular, are all in terms of the current state of the art, rather than being absolutely strict definitions in a mathematical sense. A small amount of deviation is allowed, and being approximately parallel or approximately perpendicular is acceptable. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.
[0081] It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.
[0082] FIG1 is a schematic structural diagram of an electronic device 1000 provided in an embodiment of the present application.
[0083] As shown in FIG1 , electronic device 1000 may be a device with a camera function, such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, an in-vehicle device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet. The electronic device 1000 of the embodiment shown in FIG1 is described using a mobile phone as an example.
[0084] FIG2 is a partial cross-sectional view of the electronic device 1000 shown in FIG1 taken along line AA in one embodiment.
[0085] 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 may be a rear camera module or a front camera module. It should be noted that Figure 1 and the related figures below only schematically illustrate some components included in the electronic device 1000, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 1 and the figures below. In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may also not include the screen 300.
[0086] For ease of description, the width direction of electronic device 1000 is defined as the X-axis. The length direction of electronic device 1000 is defined as the Y-axis. The thickness direction of electronic device 1000 is defined as the Z-axis. It is understood that the coordinate system of electronic device 1000 can be flexibly configured according to specific practical needs. In this embodiment, the X-axis direction is defined as the first direction, the Y-axis direction is defined as the second direction, and the Z-axis direction is defined as the third direction.
[0087] As shown in Figures 1 and 2, the device housing 200 may include a frame 201 and a back cover 202. The back cover 202 is fixed to the frame 201. For example, the back cover 202 may be fixed to the frame 201 by adhesive. The back cover 202 may also be integrally formed with the frame 201, that is, the back cover 202 and the frame 201 form a single unitary structure.
[0088] In one embodiment, the screen 300 can be located on the side of the frame 201 away from the back cover 202. In this case, the screen 300 and the back cover 202 can be located on either side of the frame 201. The screen 300, the frame 201, and the back cover 202 together enclose 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, a receiver, or a microphone. The screen 300 can be either flat or curved.
[0089] For example, the camera module 100 can be located inside the electronic device 1000. The camera module 100 can be located on the side of the screen 300 facing the back cover 202. The back cover 202 can have a light hole 203. The shape of the light hole 203 is not limited to the circular shape shown in FIG1. The light hole 203 connects the interior of the electronic device 1000 to the exterior of the electronic device 1000. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light hole 203. The camera module 100 can collect light entering the interior of the electronic device 1000.
[0090] For example, the camera module 100 can be a common camera module (i.e., the optical axis direction of the camera module 100 is the Z-axis direction). In some embodiments, the camera module 100 can also be a periscope camera module (i.e., the optical axis direction of the camera module 100 is any direction on the XY plane). It will be understood that the camera module 100 of this embodiment is described using a common camera module as an example.
[0091] Fig. 3 is a schematic structural diagram of an embodiment of the camera module 100 shown in Fig. 1. Fig. 4 is a partially exploded schematic diagram of an embodiment of the camera module 100 shown in Fig. 3.
[0092] As shown in Figures 3 and 4, the camera module 100 may include a motor 1, a lens 2, an iris 3, a module circuit board 4, an image sensor 5, a filter holder 6, and a filter 7. It is understood that the image sensor 5 is also called a photosensitive chip or a photosensitive element. The image sensor 5 is used to collect ambient light and convert the image information carried by the ambient light into an electrical signal. For example, the optical axis direction of the lens 2 is the same as the optical axis direction of the camera module 100.
[0093] It is understood that the optical axis direction of the camera module 100, the optical axis direction of the motor 1, and the optical axis direction of the lens 2 are all in the same direction. In addition, for ease of description, the X-axis direction is defined as the width direction of the camera module 100. The Y-axis direction is the length direction of the camera module 100. The Z-axis direction is the optical axis direction of the camera module 100. In other embodiments, the coordinate system setting of the camera module 100 can be flexibly set according to specific actual needs.
[0094] For example, the lens 2 can be mounted on the motor 1. The mounting position and method of the lens 2 and the motor 1 will be described in detail below with reference to the relevant drawings. Detailed description is omitted here.
[0095] It is understandable that the motor 1 can be used to achieve auto focus (AF) by controlling the movement of the lens 2 along the Z-axis direction. In addition, the motor 1 can also control the movement of the lens 2 along a plane perpendicular to the optical axis (i.e., the XY plane). In this way, when the camera module 100 collects ambient light, if the electronic device 1000 vibrates in the XY plane due to external force, the movement of the lens 2 on the XY plane can be controlled by the motor 1 to offset the jitter stroke of the lens 2 on the XY plane, so as to avoid or reduce the position offset of the lens 2 caused by the jitter. In other words, the camera module 100 of the present application can control the movement of the lens 2 on the XY plane by the motor 1, thereby achieving optical image stabilization (OIS) of the camera module 100 and improving the imaging quality of the camera module 100.
[0096] For example, the variable aperture 3 can be located on the light-entering side of the lens 2. The variable aperture 3 has an aperture hole 3a. The size of the aperture hole 3a can be automatically adjusted. Light can enter the lens 2 through the aperture hole 3a of the variable aperture 3.
[0097] As shown in Figure 2, in one embodiment, the image sensor 5 is fixed to the module circuit board 4 and electrically connected to the module circuit board 4. At this time, signals can be transmitted between the image sensor 5 and the module circuit board 4. The filter holder 6 is fixedly connected to the module circuit board 4. The filter holder 6 and the image sensor 5 are located on the same side of the module circuit board 4. The filter holder 6 is provided with a light-transmitting hole 6a. The filter 7 is fixedly connected to the filter holder 6. The filter 7 can be located in the light-transmitting hole 6a. The filter 7 is also arranged opposite to the image sensor 5. The filter 7 can be used to filter infrared light or blue light in the light before entering the image sensor 5, thereby ensuring that the image sensor 5 has better imaging quality.
[0098] As shown in Figure 2, in one embodiment, the motor 1 is fixed to the module circuit board 4 and is located on the same side of the module circuit board 4 as the image sensor 5. In the Z-axis direction, the image sensor 5, the optical filter 7, the lens 2, and the variable aperture 3 are arranged in sequence. In this case, the image sensor 5 is located on the light-emitting side of the lens 2. The optical filter 7 is located between the lens 2 and the image sensor 5.
[0099] It can be understood that compared with the solution of fixing the motor 1 on the filter holder 6, this embodiment can avoid stacking of the motor 1 and the filter holder 6 in the Z-axis direction by fixing the motor 1 on the module circuit board 4, that is, the motor 1 and the filter holder 6 can be staggered in the XY plane, thereby greatly reducing the height of the camera module 100.
[0100] As shown in Figure 2, in one embodiment, the motor 1 has an escape hole 1a. A portion of the filter holder 6 can pass through the escape hole 1a and enter the interior of the drive motor 1. In this case, a portion of the filter holder 6 is located inside the drive motor 1. This allows the filter holder 6 and the drive motor 1 to overlap in the Z-axis direction, significantly reducing the height of the camera module 100.
[0101] FIG5 is a partially exploded schematic diagram of the motor 1 shown in FIG4 in one embodiment.
[0102] As shown in Figure 5, in one embodiment, the motor 1 includes an anti-shake drive module 10, a focus drive module 20, a limit bracket 30, and a housing 40. It will be appreciated that by placing the focus drive module 20 on the anti-shake drive module 10, the anti-shake drive module 10 and the focus drive module 20 form an integrated motor, namely, the motor 1. As a result, compared to a split motor in which the anti-shake drive module 10 and the focus drive module 20 are separately arranged, the motor 1 of this embodiment is smaller in size, facilitating the miniaturization of the motor 1 and thereby conserving internal space within the electronic device 1000.
[0103] FIG. 6 is a partial exploded view of the anti-shake driving module 10 shown in FIG. 5 in one embodiment.
[0104] As shown in Figures 5 and 6, in one embodiment, the anti-shake drive module 10 includes a base 11, an anti-shake carrier 12, and an anti-shake drive mechanism 13. The anti-shake carrier 12 is movably connected to the base 11. The anti-shake carrier 12 can move relative to the base 11 along the X-axis direction and / or the Y-axis direction. The base 11 can be fixed on the module circuit board 4 (see Figure 4). At this time, the position of the base 11 relative to the module circuit board 4 remains unchanged. The base 11 can also be called an anti-shake stator. The anti-shake carrier 12 is movably connected to the base 11, and the anti-shake carrier 12 can also be called an anti-shake stator.
[0105] Illustratively, the anti-shake carrier 12 is frame-shaped. It includes a first side 121 and a third side 123 disposed opposite each other, and a second side 122 and a fourth side 124 disposed opposite each other. The second side 122 and the fourth side 124 are connected between the first side 121 and the third side 123.
[0106] Exemplarily, the anti-shake drive mechanism 13 includes a first anti-shake coil 131, a first anti-shake magnetic component 132, a second anti-shake coil 133 and a second anti-shake magnetic component 134. The first anti-shake coil 131 is fixed on the base 11. The first anti-shake magnetic component 132 is fixed on the first side 121 of the anti-shake carrier 12. The first anti-shake coil 131 faces the first anti-shake magnetic component 132 to drive the anti-shake carrier 12 to move along the X-axis relative to the base 11. The second anti-shake coil 133 is fixed on the base 11. The second anti-shake magnetic component 134 is fixed on the second side 122. The second anti-shake coil 133 faces the second anti-shake magnetic component 134 to drive the anti-shake carrier 12 to move along the Y-axis relative to the base 11.
[0107] In other implementations, the anti-shake driving mechanism 13 may also adopt other driving mechanisms, which is not specifically limited in this application.
[0108] As shown in Figure 6, the anti-shake carrier 12 exemplarily includes a first sliding shaft 51 and a second sliding shaft 52. This can be achieved by providing a first groove 53 and a second groove 54 in the anti-shake carrier 12. At this point, the first sliding shaft 51 is fixed in the first groove 53 by means of glue or welding, with a portion of the outer surface of the first sliding shaft 51 exposed relative to the first groove 53. Furthermore, the second sliding shaft 52 is fixed in the second groove 54 by means of glue or welding, with a portion of the outer surface of the second sliding shaft 52 exposed relative to the second groove 54. In other embodiments, the first sliding shaft 51 and the second sliding shaft 52 can also be part of the anti-shake carrier 12 as an integral structural component.
[0109] As shown in FIG5 and FIG6 , the third side portion 123 of the anti-shake carrier 12 is provided with a through hole 55 . The through hole 55 passes through the inner surface 56 a and the outer surface 56 b of the anti-shake carrier 12 .
[0110] As shown in Figure 5, the focus drive module 20 includes a focus carrier 21, a focus drive mechanism 22, and a circuit board assembly 23. For example, the focus drive mechanism 22 includes a focus coil 221 and a focus magnetic member 222. The focus magnetic member 222 can be a magnet or other magnetic component.
[0111] FIG. 7 is a partially exploded view of one embodiment of the circuit board assembly 23 shown in FIG. 5 .
[0112] 5 and 7 , the circuit board assembly 23 includes a focus circuit board 231, a focus driver chip 232, a focus magnetic conductive member 233, and a focus sensor 234. In other embodiments, the circuit board assembly 23 may not include the focus magnetic conductive member 233 and the focus sensor 234.
[0113] Fig. 8 is a schematic diagram of a partial structure of the motor 1 shown in Fig. 4 in one embodiment. For example, Fig. 8 may be a schematic diagram of the assembly of the circuit board assembly 23 and the focus coil 221 in one embodiment.
[0114] As shown in FIG. 7 and FIG. 8 , illustratively, the focus driving chip 232 and the focus sensor 234 are both fixed on the focus circuit board 231 and are both electrically connected to the focus circuit board 231 .
[0115] As shown in Figures 7 and 8, the focus coil 221 is illustratively fixed to and electrically connected to the focus circuit board 231. It will be appreciated that the input and output ends of the focus coil 221 form a current loop with the focus driver chip 232 via the focus circuit board 231. In this case, the focus driver chip 232 can control the current flow through the focus coil 221 (e.g., whether current is flowing or the magnitude of the current when it is flowing) via the focus circuit board 231.
[0116] For example, the focus coil 221 can be arranged around the focus driver chip 232 and the focus sensor 234. In this way, the focus driver chip 232 and the focus sensor 234 can effectively utilize the inner space of the focus coil 221, thereby greatly improving the space utilization of the motor 1.
[0117] It is understood that in other embodiments, the focus coil 221 may also be a part of the circuit board assembly 23. Thus, when the circuit board assembly 23 is sold as a sales unit, the focus coil 221 may also be sold as a part of the circuit board assembly 23.
[0118] As shown in FIG. 7 , the focusing magnetic conductive member 233 includes a first focusing magnetic conductive member 2331 , a second focusing magnetic conductive member 2332 and a third focusing magnetic conductive member 2333 .
[0119] Exemplarily, the first focusing magnetic conductive member 2331 includes a front surface 2334 and a top surface 2335 and a bottom surface 2336 disposed opposite to each other. The front surface 2334 is connected between the top surface 2335 and the bottom surface 2336.
[0120] In one embodiment, the second focusing magnetic conductive member 2332 is fixedly connected to the top surface 2335 of the first focusing magnetic conductive member 2331. A portion of the second focusing magnetic conductive member 2332 protrudes relative to the front surface 2334 of the first focusing magnetic conductive member 2331. The third focusing magnetic conductive member 2333 is fixedly connected to the bottom surface 2336 of the first focusing magnetic conductive member 2331. A portion of the third focusing magnetic conductive member 2333 protrudes relative to the front surface 2334 of the first focusing magnetic conductive member 2331. In this way, in the Z-axis direction, the second focusing magnetic conductive member 2332 and the third focusing magnetic conductive member 2333 can be fixedly connected to the first focusing magnetic conductive member 2331 at intervals, and both protrude relative to one side of the first focusing magnetic conductive member 2331. It is understandable that the second focusing magnetic member 2332 can be fixedly connected to the first focusing magnetic member 2331 by bending (the bending angle is not limited), or can be fixedly connected to the first focusing magnetic member 2331 by non-bending. In addition, the second focusing magnetic member 2332 can form an integrally molded structure with the first focusing magnetic member 2331. The second focusing magnetic member 2332 can also be fixedly connected to the first focusing magnetic member 2331 by bonding, welding, etc. Among them, the connection method between the third focusing magnetic member 2333 and the first focusing magnetic member 2331 can refer to the connection method between the second focusing magnetic member 2332 and the first focusing magnetic member 2331. The details will not be repeated here.
[0121] In other embodiments, the second focusing magnetic conductive member 2332 and the third focusing magnetic conductive member 2333 may also be fixedly connected to the front surface 2334 of the first focusing magnetic conductive member 2331 at intervals.
[0122] In other embodiments, the focusing magnetic conductive component 233 may not include the second focusing magnetic conductive component 2332 and the third focusing magnetic conductive component 2333 .
[0123] As shown in FIG8 , the focusing magnetic conductive member 233 is fixed to a side of the focusing circuit board 231 away from the focusing coil 221 .
[0124] Exemplarily, the front side 2334 of the first focusing magnetic conductive component 2331 is fixed to a surface of the focusing circuit board 231 away from the focusing coil 221 .
[0125] Fig. 9 is a partial structural diagram of an embodiment of the motor 1 shown in Fig. 4 at different angles. For example, Fig. 9 may be a schematic diagram of the assembly of the anti-shake carrier 12, the circuit board assembly 23, and the focus coil 221.
[0126] As shown in Figure 9, the focus circuit board 231 is fixed to the anti-shake carrier 12. At this time, the focus coil 221 can be fixed to the anti-shake carrier 12 via the focus circuit board 231. For example, the focus circuit board 231 is fixed to the outer side surface 56a of the anti-shake carrier 12 and is located on the third side 123 of the anti-shake carrier 12.
[0127] For example, the focus circuit board 231 is fixed to the outer surface of the anti-shake carrier 12. At least a portion of the focus coil 221 can be located within the through hole 55 of the anti-shake carrier 12. It will be appreciated that by placing at least a portion of the focus coil 221 within the through hole 55 of the anti-shake carrier 12, the structural space of the anti-shake carrier 12 can be fully utilized, thereby facilitating the miniaturization of the motor 1.
[0128] In this embodiment, the plane around which the wires of the focus coil 221 are wound can be parallel to the optical axis. In this case, the focus coil 221 is arranged vertically, so that the focus coil 221 occupies a smaller area in the XY plane, thereby facilitating the miniaturization of the motor 1.
[0129] Fig. 10 is a schematic diagram of a partial structure of the motor 1 shown in Fig. 4 in one embodiment. For example, Fig. 10 may be a schematic diagram of the assembly of the base 11, the anti-shake carrier 12, the circuit board assembly 23, and the focus coil 221.
[0130] As shown in Figure 10, when the focus circuit board 231 is fixed to the anti-shake carrier 12, the focus circuit board 231 can be located between the anti-shake carrier 12 and the base 11. It will be understood that when the anti-shake carrier 12 moves relative to the base 11 in the XY plane, the anti-shake carrier 12 can drive the circuit board assembly 23 and the focus coil 221 to move in the XY plane.
[0131] Fig. 11 is a schematic diagram of a partial structure of the focus driving module 20 shown in Fig. 5 in one embodiment. For example, Fig. 11 may be a schematic diagram of the assembly of the focus carrier 21 and the focus magnetic member 222.
[0132] As shown in Figure 11, the focusing magnetic member 222 is fixed on the focusing carrier 21. The polarity direction of the focusing magnetic member 222 can be parallel to the direction of the optical axis. At this time, the focusing magnetic member 222 can be arranged vertically, thereby reducing the space occupied by the focusing magnetic member 222 in the XY plane. It can be understood that the polarity direction of the focusing magnetic member 222 can be the direction of the north pole of the focusing magnetic member 222 toward the south pole, or the direction of the south pole toward the north pole. This embodiment is described by taking the direction of the north pole of the focusing magnetic member 222 toward the south pole as an example of the polarity direction of the focusing magnetic member 222.
[0133] Exemplarily, the focusing magnetic member 222 may be fixed on the focusing carrier 21 by means of adhesive or the like.
[0134] For example, a groove can be provided in the focus carrier 21. The focus magnetic member 222 is then placed within the groove. This improves the structural integrity of the focus magnetic member 222 and the focus carrier 21. Furthermore, the focus magnetic member 222 can utilize the structural space of the focus carrier 21, and the focus magnetic member 222 does not significantly increase the size of the focus drive module. In other embodiments, the focus magnetic member 222 can be embedded within the focus carrier 21 through an injection molding process.
[0135] Figure 12 is a schematic diagram of a portion of the motor 1 shown in Figure 4 in one embodiment. Figure 13 is a schematic diagram of the portion of the motor 1 shown in Figure 12 at another angle. For example, Figure 12 may be a schematic diagram of the assembly of the focus carrier 21 and the anti-shake carrier 12.
[0136] As shown in Figures 12 and 13, the focus carrier 21 is located inside the anti-shake carrier 12. It is understood that when the focus carrier 21 is located inside the anti-shake carrier 12, the anti-shake carrier 12 can be positioned around the focus carrier 21. This "surrounding" can mean that the anti-shake carrier 12 surrounds the focus carrier 21 completely, or that a portion of the anti-shake carrier 12 surrounds the focus carrier 21. In this embodiment, the anti-shake carrier 12 is frame-shaped. In this case, the anti-shake carrier 12 surrounds the focus carrier 21.
[0137] It is understandable that in some embodiments, the anti-shake carrier is located inside the focus carrier. In this case, when the camera module needs to focus, the focus carrier needs to drive the anti-shake carrier, lens, and variable aperture to move along the Z-axis. As a result, the weight of the mover composed of the focus carrier, anti-shake carrier, lens, and variable aperture is relatively heavy, resulting in the focus drive mechanism needing to increase its volume to increase the driving force. Therefore, this arrangement is not conducive to the lightweight and miniaturized design of the motor. In this embodiment, by arranging the focus carrier 21 inside the anti-shake carrier 12. In this case, when the camera module 100 needs to focus, the focus carrier 21 needs to drive the lens 2 and variable aperture 3 to move along the Z-axis. In this way, the mover during the focusing process of this embodiment can omit the anti-shake carrier. That is, the weight of the mover composed of the focus carrier 21, lens 2, and variable aperture 3 is relatively light, which is conducive to the miniaturization of the focus drive mechanism 22. The motor 1 of this embodiment can achieve a lightweight and miniaturized design.
[0138] In addition, in this embodiment, the distance between the connection position between the focusing carrier 21 and the anti-shake carrier and the center of gravity of the mover formed by the focusing carrier 21, the lens 2 and the variable aperture 3 is relatively close, which is beneficial to reducing the risk of the mover overturning.
[0139] It is understandable that, compared to the solution in which the anti-shake carrier is on the inner side of the focus carrier, the anti-shake carrier requires at least two anti-shake drive mechanisms to push the anti-shake carrier to move in the XY plane. In this way, the motor needs to arrange at least two sets of lines to provide signals and power to the anti-shake drive mechanisms. And at least two sets of lines need to pass through the focus carrier. Therefore, the power-on setting of this solution is relatively complicated, which increases the difficulty of setting up the motor. In this embodiment, by setting the focus carrier 21 on the inner side of the anti-shake carrier 12, since the focus carrier 21 requires a set of focus drive mechanisms 22 to push the focus carrier 21 to move along the Z-axis direction, the motor 1 also needs a set of lines to provide signals and power to the focus drive mechanism 22, that is, a set of lines needs to pass through the anti-shake carrier 12. Therefore, the power-on scheme of the solution of this embodiment is relatively simple, which can greatly reduce the difficulty of setting up the motor 1.
[0140] Furthermore, by positioning the focus carrier 21 inside the anti-shake carrier 12, the focus coil and focus magnet can be arranged closer to the lens. Thus, when the focus coil and focus magnet are arranged vertically, they can partially protrude from the upper surface of the motor 1. It is understood that this protruding portion can be positioned inside the camera trim to further improve space utilization within the camera trim.
[0141] As shown in Figures 12 and 13, the focus carrier 21 is slidably connected to the anti-shake carrier 12 in the Z-axis direction. In this way, the focus carrier 21 can move relative to the anti-shake carrier 12 along the Z-axis direction, that is, the focus carrier 21 can move relative to the base 11 along the Z-axis direction.
[0142] It can be understood that since the anti-shake carrier 12 can move relative to the base 11 in the XY plane, the focusing carrier 21 is slidably connected to the anti-shake carrier 12 in the Z-axis direction, so that when the anti-shake carrier 12 moves relative to the base 11 in the XY plane, the anti-shake carrier 12 can also drive the focusing carrier 21 to move relative to the base 11 in the XY plane.
[0143] In one embodiment, the focus carrier 21 is slidably connected to the anti-shake carrier 12 along the Z-axis direction via the first sliding shaft 51 and the second sliding shaft 52 .
[0144] It is understood that, compared to the solution in which the focus carrier 21 is connected to the anti-shake carrier 12 via ball bearings, the focus carrier 21 and the anti-shake carrier 12 in this embodiment can achieve surface contact. This ensures that when the focus carrier 21 slides relative to the anti-shake carrier 12 along the Z-axis, the focus carrier 21 and the anti-shake carrier 12 have better stability. In addition, due to the large contact area between the focus carrier 21 and the anti-shake carrier 12, when the focus carrier 21 or the anti-shake carrier 12 generates pressure in the XY plane, the focus carrier 21 or the anti-shake carrier 12 is not easily deformed by the high pressure, thereby greatly improving the reliability of the motor 1.
[0145] In other embodiments, the focusing carrier 21 may also be slidably connected to the anti-shake carrier 12 along the Z-axis direction by means of a ball bearing.
[0146] As shown in Figures 12 and 13, in one embodiment, the focusing carrier 21 is provided with a first sliding groove 211 and a second sliding groove 212 spaced apart from each other. A portion of the first sliding shaft 51 is disposed in the first sliding groove 211, and a portion of the second sliding shaft 52 is disposed in the second sliding groove 212.
[0147] It can be understood that through the cooperation between the first sliding shaft 51 and the first sliding groove 211, and the cooperation between the second sliding shaft 52 and the second sliding groove 212, the focusing carrier 21 is limited in some directions on the XY plane, that is, the movement of the focusing carrier 21 in these directions is avoided, thereby ensuring the stability of the focusing carrier 21.
[0148] In one embodiment, the first slide shaft 51 can be tightly fitted with the focus carrier 21. The second slide shaft 52 can be loosely fitted with the focus carrier 21. For example, the first slide groove 211 is configured to be V-shaped. The second slide groove 212 is configured to be L-shaped or U-shaped. In this way, the first slide shaft 51 is enclosed by the V-shaped first slide groove 211. It is understood that by configuring the first slide shaft 51 to be tightly fitted with the focus carrier 21 and the second slide shaft 52 to be loosely fitted with the focus carrier 21, the difficulty of assembling the focus carrier 21 and the anti-shake carrier 12 can be reduced.
[0149] In other embodiments, the focusing carrier 21 may be connected to the first sliding shaft 51 and the second sliding shaft 52 in other ways. For example, a first through hole and a second through hole may be provided on the focusing carrier 21. The first sliding shaft 51 and the second sliding shaft 52 are respectively sleeved on the first through hole and the second through hole.
[0150] FIG14 is a partial cross-sectional view of the camera module 100 shown in FIG3 taken along line BB according to an embodiment of the present invention.
[0151] As shown in Figure 14, the lens 2 is mounted on a focus carrier 21. Thus, when the focus carrier 21 moves relative to the anti-shake carrier 12 along the Z-axis, the focus carrier 21 can drive the lens 2 to move along the Z-axis, allowing the camera module 100 to achieve auto focus (AF). Furthermore, because the anti-shake carrier 12 can also drive the focus carrier 21 to move relative to the base 11 within the XY plane, the focus carrier 21 can also drive the lens 2 to move relative to the base 11 within the XY plane. At this point, the camera module 100 can achieve optical image stabilization (OIS), thereby improving the imaging quality of the camera module 100.
[0152] In one embodiment, the inner side of the focus carrier 21 may have a protrusion 213. When the lens 2 is mounted on the focus carrier 21, the protrusion 213 may be positioned opposite a portion of the lens barrel of the lens 2. Thus, by providing an adhesive layer 214 between the protrusion 213 and the lens barrel of the lens 2, the lens 2 is stably fixed to the focus carrier 21. Furthermore, the protrusion 213 and the adhesive layer 214 may form an interlocking structure, further enhancing the stability of the connection between the focus carrier 21 and the lens 2.
[0153] 14 , when the focus carrier 21 is placed on the anti-shake carrier 12 , the focus coil 221 faces the focus magnetic member 222 . For example, the plane on which the wire of the focus coil 221 is wound may be parallel to the polarity direction of the focus magnetic member 222 .
[0154] It is understood that when the focus coil 221 is energized, the focus coil 221 and the focus magnetic member 222 can generate a force that interacts with each other. In this way, when the focus magnetic member 222 is subjected to a force, the focus carrier 21 can move relative to the anti-shake carrier 12 along the Z-axis under this force.
[0155] It can be understood that by changing the magnetic pole position of the focusing magnetic member 222 (that is, the south pole of the focusing magnetic member 222 is close to the focusing coil 221, or the north pole of the focusing magnetic member 222 is close to the focusing coil 221) or changing the direction of the current signal on the focusing coil 221, the force direction of the focusing magnetic member 222 is changed, and then the moving direction of the focusing carrier 21 is changed (for example, moving along the positive direction of the Z axis, or moving along the negative direction of the Z axis).
[0156] As shown in Figure 14, the focusing magnetic conductive member 233 faces the focusing magnetic member 222. The focusing magnetic conductive member 233 is used to generate a magnetic attraction force with the focusing magnetic member 222. It can be understood that since the focusing magnetic conductive member 233 is fixed to the anti-shake carrier 12 through the focusing circuit board 231, and the focusing magnetic member 222 is fixed to the focusing carrier 21, when the focusing magnetic conductive member 233 generates a magnetic attraction force with the focusing magnetic member 222, the focusing carrier 21 is more tightly matched with the anti-shake carrier 12 under the action of the magnetic attraction force. In this way, the focusing carrier 21 can be further limited in some directions on the XY plane, that is, the movement or shaking of the focusing carrier 21 in these directions can be avoided, thereby ensuring the stability of the focusing carrier 21.
[0157] FIG15 is a simplified schematic diagram of the forces acting on the focusing magnetic conductive member 233 , the focusing magnetic member 222 and the focusing carrier 21 shown in FIG14 when they move in the positive direction along the Z axis.
[0158] As shown in Figure 15, in this embodiment, the focusing magnetic permeable member 233 includes a first focusing magnetic permeable member 2331, a second focusing magnetic permeable member 2332, and a third focusing magnetic permeable member 2333. In the Z-axis direction, the second focusing magnetic permeable member 2332 and the third focusing magnetic permeable member 2333 are spaced apart from each other on the first focusing magnetic permeable member 2331, and both protrude relative to the front surface 2334 of the first focusing magnetic permeable member 2331. Furthermore, the center of the focusing magnetic member 222 is located between the center of the second focusing magnetic permeable member 2332 and the center of the third focusing magnetic permeable member 2333.
[0159] As shown in Figure 15, when the focusing magnetic member 222 moves along the positive direction a1 of the Z axis (indicated by a solid line with an arrow in Figure 15), the focusing magnetic member 222 moves from the first position to the second position, and the magnetic attraction between the first focusing magnetic member 2331 and the focusing magnetic member 222 can cause the focusing magnetic member 222 to generate a first restoring force b1 along the negative direction of the Z axis (indicated by a dotted line with an arrow in Figure 15), and the magnetic attraction between the second focusing magnetic member 2332 and the focusing magnetic member 222 can cause the focusing magnetic member 222 to generate a second restoring force b2 along the positive direction of the Z axis (indicated by a dotted line with an arrow in Figure 15). In this way, the first restoring force and the second restoring force can be roughly offset or completely offset. At this time, the stability of the focusing carrier 21 during the movement along the positive direction of the Z axis is better.
[0160] FIG16 is a simplified schematic diagram of the forces acting on the focusing magnetic conductive member 233 , the focusing magnetic member 222 and the focusing carrier 21 shown in FIG14 when they move in the negative direction along the Z axis.
[0161] As shown in Figure 16, when the focusing magnetic member 222 moves along the negative direction a2 of the Z axis (indicated by a solid line with an arrow in Figure 16), the focusing magnetic member 222 moves from the first position to the third position, and the magnetic attraction between the first focusing magnetic member 2331 and the focusing magnetic member 222 can cause the focusing magnetic member 222 to generate a third restoring force b3 along the positive direction of the Z axis (indicated by a dotted line with an arrow in Figure 16), and the magnetic attraction between the third focusing magnetic member 2333 and the focusing magnetic member 222 can cause the focusing magnetic member 222 to generate a fourth restoring force b4 along the negative direction of the Z axis. In this way, the third restoring force and the fourth restoring force can be roughly offset or completely offset. At this time, the stability of the focusing carrier 21 during the movement along the Z axis is better.
[0162] Fig. 17 is a partially exploded schematic diagram of an embodiment of the motor 1 shown in Fig. 4 at one angle. Fig. 18 is a partially exploded schematic diagram of an embodiment of the motor 1 shown in Fig. 4 at another angle.
[0163] As shown in Figures 17 and 18, there are at least two contact positions between the focus carrier 21 and the first sliding shaft 51, including, for example, a first contact position M1 (the area enclosed by the dashed lines in Figures 17 and 18) and a second contact position M2 (the area enclosed by the dotted lines in Figures 17 and 18). The second contact position M2 is located closer to the base 11 than the first contact position M1, i.e., the distance between the second contact position M2 and the bottom surface of the base 11 is less than the distance between the first contact position M1 and the bottom surface of the base 11.
[0164] There is at least one contact position between the focus carrier and the second sliding shaft 52, including, for example, a third contact position N1 (the area enclosed by the dashed line in Figures 17 and 18). The second contact position M2 is positioned closer to the bottom surface of the base 11 relative to the third contact position N1. That is, the distance between the third contact position N1 and the bottom surface of the base 11 is greater than the distance between the second contact position M2 and the bottom surface of the base 11.
[0165] Relative to the second sliding shaft 52, the focusing magnetic conductive member 233 (the area between the two dotted lines in Figures 17 and 18) is arranged close to the first sliding shaft 51. In other words, the distance between the focusing magnetic conductive member 233 and the first sliding shaft 51 is smaller than the distance between the focusing magnetic conductive member 233 and the second sliding shaft 52. It can be understood that the parts on both sides of the focusing magnetic conductive member 233 in Figure 17 can be the first reinforcement plate 233a and the second reinforcement plate 233b. The first reinforcement plate 233a and the second reinforcement plate 233b can be used to improve the structural strength of the focusing magnetic conductive member 233. The first reinforcement plate 233a and the second reinforcement plate 233b can form an integrally molded structure with the focusing magnetic conductive member 233, or can be fixedly connected to the focusing magnetic conductive member 233 by bonding or the like. In other embodiments, the first reinforcement plate 233a and the second reinforcement plate 233b may also be excluded.
[0166] It is understandable that in some embodiments, when the focusing magnetic conductive member 233 and the focusing magnetic member 222 are provided on one side of the focusing carrier 21, and the focusing magnetic conductive member 233 and the focusing magnetic member 222 are not provided on the other side of the focusing carrier 21, when the focusing carrier 21 moves along the Z-axis direction, the other side of the focusing carrier 21 is susceptible to being flipped about the flip axis due to gravity. Specifically, when the display screen 300 (see FIG. 2 ) of the electronic device 1000 is facing away from the user (i.e., the camera module 100 is facing the user), the first flip axis is the line connecting the bottom boundary line of the second contact position M2 and the bottom boundary line of the third contact position N1 (the P1-P2 line shown in FIG. 17 and FIG. 18 ). When the display screen 300 of the electronic device 1000 is facing the user (i.e., the camera module 100 is facing away from the user), the second flip axis is the line connecting the top boundary line of the first contact position M1 and the top boundary line of the third contact position N1 (line P3-P4 shown in Figures 17 and 18). When the electronic device 1000 is standing on its side, the third flip axis is the line connecting the right boundary line of the first contact position M1 and the right boundary line of the second contact position M2 (line P5-P6 shown in Figures 17 and 18).
[0167] In the present embodiment, by setting the focusing magnetic conductive member 233 close to the first sliding shaft 51, the center position of the magnetic attraction force generated by the focusing magnetic conductive member 233 and the focusing magnetic member 222 is set close to the first sliding shaft 51. In this way, no matter whether the focusing carrier 21 is flipped with the first flip axis (P1-P2 line) as the axis or the second flip axis (P3-P4 line) as the axis, the vertical distance between the center position of the magnetic attraction force and the flip axis (P1-P2 line or P3-P4 line) (that is, the force arm of the magnetic attraction force) will become longer, and the torque of the magnetic attraction force will increase. Among them, the torque of the magnetic attraction force is equal to the product of the magnitude of the magnetic attraction force and the force arm of the magnetic attraction force. Due to the increase in the torque of the magnetic attraction force, the ability of the focusing carrier 21 to resist the flipping due to gravity is increased, that is, the stability of the focusing carrier 21 in the movement along the Z-axis direction is better.
[0168] In one embodiment, the product of the vertical distance between the center of the magnetic attraction generated by the focus conductive member 233 and the focus magnetic member 222 and the first tilt axis (line P1-P2) and the magnetic attraction is greater than the gravitational moment of the focus actuator. It is understood that the focus actuator can be related structures along the Z-axis, such as the focus carrier 21, the focus magnetic member 222, the lens 2, and the variable aperture 3.
[0169] In one embodiment, the product of the vertical distance from the center of the magnetic attraction generated by the focusing magnetic conductive member 233 and the focusing magnetic member 222 to the second flip axis (line P3 - P4 ) and the magnetic attraction is greater than the gravity moment of the focusing mover.
[0170] In one embodiment, the product of the vertical distance from the center of the magnetic attraction generated by the focusing magnetic conductive member 233 and the focusing magnetic member 222 to the third flip axis (line P5-P6) and the magnetic attraction is greater than the gravity moment of the focusing mover.
[0171] In one embodiment, the distance between the center of the focusing magnetic member 233 and the first sliding axis 51 is a. The distance between the first sliding axis 51 and the second sliding axis 52 is b. Wherein, a and b satisfy: In this way, while the ability of the focusing carrier 21 to resist the flipping of gravity is increased, the focusing carrier 21 can also closely cooperate with the first sliding shaft 51 and the second sliding shaft 52 under the action of the magnetic attraction generated by the focusing magnetic conductive part 233 and the focusing magnetic part 222.
[0172] FIG19 is a partial cross-sectional view of an embodiment of the camera module 100 shown in FIG3 at line CC.
[0173] As shown in FIG19 , the focus sensor 234 may be disposed opposite to the focus magnetic member 222 . The focus sensor 234 may be used to detect the magnetic field strength when the focus magnetic member 222 is at different positions, so as to detect the position of the focus carrier 21 .
[0174] It is understandable that when the focusing carrier 21 moves relative to the anti-shake carrier 12 along the Z-axis direction, the focusing carrier 21 can drive the focusing magnetic part 222 to move relative to the anti-shake carrier 12 along the Z-axis direction. The focusing sensor 234 can detect the magnetic field strength at the location of the focusing magnetic part 222. In this way, when the focusing sensor 234 detects the magnetic field strength of the focusing magnetic part 222, the displacement of the focusing carrier 21 can be determined by the magnetic field strength. It is understandable that through the mutual cooperation between the focusing sensor 234 and the focusing magnetic part 222, the displacement of the focusing carrier 21 relative to the anti-shake carrier 12 along the Z-axis direction can be accurately controlled, thereby realizing the closed-loop design of the lens 2 assembly.
[0175] As shown in Figure 19, the limit bracket 30 is fixed to the anti-shake carrier 12. A portion of the lens 2 is located on the side of the limit bracket 30 facing the module circuit board. A portion of the lens 2 passes through the limit bracket 30 and is located on the side of the limit bracket 30 facing away from the module circuit board. This way, when the focus carrier 21 moves the lens 2 in the positive direction of the Z axis, the limit bracket 30 can limit the lens 2 in the Z direction, preventing the focus carrier 21 from sliding off the anti-shake carrier 12 in the Z direction.
[0176] In one embodiment, a buffer pad can be provided on the position-limiting bracket 30. When the focus carrier 21 drives the lens 2 to move to the highest position along the positive direction of the Z axis, the lens 2 can contact the buffer pad. Compared to a solution in which the lens 2 directly contacts the position-limiting bracket 30, the buffer pad of this embodiment can prevent the lens 2 from being damaged or displaced due to direct collision with the position-limiting bracket 30.
[0177] As shown in Figure 19, the housing 40 is fixed to the module circuit board 4. The housing 40 covers the anti-shake drive module 10, the focus drive module 20, and a portion of the lens 2. A portion of the lens 2 passes through the housing 40 and is located outside the housing 40. The housing 40 serves to protect the anti-shake drive module 10, the focus drive module, and the lens 2.
[0178] The above description specifically describes the structure of the focus driving module 20 of the camera module 100 in conjunction with the relevant drawings. The following description specifically describes the circuit arrangement between the focus driving chip 232 and the module circuit board 4 in conjunction with the relevant drawings.
[0179] FIG20 is a schematic structural diagram of an embodiment of the base 11 shown in FIG6 at different angles.
[0180] As shown in FIG20 , the base 11 is provided with a plurality of connection terminals 50 . For example, the connection terminals 50 include a first connection terminal 56 , a second connection terminal 57 , a third connection terminal 58 , and a fourth connection terminal 59 .
[0181] For example, multiple terminals 50 are fixed to the base 11 at intervals. For example, the first terminal 56, the second terminal 57, the third terminal 58, and the fourth terminal 59 are all conductive traces. The first terminal 56, the second terminal 57, the third terminal 58, and the fourth terminal 59 can be embedded in the base 11 at intervals.
[0182] For example, the first terminal 56 can be embedded in the first corner portion 29a of the base 11. The input end 561 of the first terminal 56 can be exposed relative to the top surface of the first corner portion 29a. The output end 562 of the first terminal 56 can be exposed relative to the bottom surface of the first corner portion 29a.
[0183] For example, the second terminal 57 can be embedded in the second corner portion 29b of the base 11. The input end 571 of the second terminal 57 can be exposed relative to the top surface of the second corner portion 29b. The output end 572 of the second terminal 57 can be exposed relative to the bottom surface of the second corner portion 29b.
[0184] For example, the third terminal 58 can be embedded in the second corner portion 29b of the base 11 and spaced apart from the second terminal 57. The input end 581 of the third terminal 58 can be exposed relative to the top surface of the second corner portion 29b and spaced apart from the input end 571 of the second terminal 57. The output end 582 of the third terminal 58 can be exposed relative to the bottom surface of the second corner portion 29b and spaced apart from the output end 572 of the second terminal 57.
[0185] For example, the fourth terminal 59 can be embedded in the third corner portion 29c of the base 11. The input end 591 of the fourth terminal 59 can be exposed relative to the top surface of the third corner portion 29c. The output end 592 of the fourth terminal 59 can be exposed relative to the bottom surface of the third corner portion 29c. The second corner portion 29b can be located between the first corner portion 29a and the third corner portion 29c.
[0186] It is understood that the output end 562 of the first terminal 56, the output end 572 of the second terminal 57, the output end 582 of the third terminal 58, and the output end 592 of the fourth terminal 59 can be used to electrically connect to the module circuit board 4 (see FIG. 19 ). In this way, an external power source can supply power to the first terminal 56, the second terminal 57, the third terminal 58, and the fourth terminal 59 through the module circuit board 4 (see FIG. 19 ).
[0187] In other embodiments, the first terminal 56, the second terminal 57, the third terminal 58, and the fourth terminal 59 may also be formed of a flexible printed circuit board. The first terminal 56, the second terminal 57, the third terminal 58, and the fourth terminal 59 may also be integrated into one flexible printed circuit board.
[0188] Fig. 21 is a schematic diagram of a circuit electrically connected to an external structure of the focus driving chip 232 shown in Fig. 5. Fig. 22 is a schematic diagram of a portion of a motor 1 shown in Fig. 4.
[0189] As shown in FIG. 21 and FIG. 22 , the focus driving module 20 further includes a plurality of wirings 28 a and a plurality of conductive springs 28 b .
[0190] For example, the plurality of traces 28a include a first trace 281 , a second trace 282 , a third trace 283 , and a fourth trace 284 . The plurality of conductive springs 28b include a first conductive spring 285 , a second conductive spring 286 , a third conductive spring 287 , and a fourth conductive spring 288 .
[0191] For example, multiple traces 28a are embedded in the anti-shake carrier 12 at intervals. For example, the first trace 281, the second trace 282, the third trace 283, and the fourth trace 284 are all conductive traces. The first trace 281, the second trace 282, the third trace 283, and the fourth trace 284 can all be embedded in the anti-shake carrier 12. In other embodiments, the positions of the first trace 281, the second trace 282, the third trace 283, and the fourth trace 284 are not specifically limited.
[0192] Exemplarily, both the input and output ends of each of the wires 28a are exposed relative to the anti-shake carrier 12. The output ends of the wires 28a are electrically connected to multiple ports of the focus driver chip 232 through the focus circuit board 231 in a one-to-one correspondence.
[0193] For example, both the input end 281a of the first trace 281 and the output end 281b of the first trace 281 can be exposed relative to the top surface of the anti-shake carrier 12. The input end 281a of the first trace 281 can be electrically connected to the SDA signal terminal of the focus driver chip 232 through the focus circuit board 231. It is understood that the SDA signal terminal can be used to transmit the serial data (SDA) signal of the I2C signal.
[0194] For example, the input end 282a of the second trace 282 can be exposed relative to the top surface of the anti-shake carrier 12. The input end 282a of the second trace 282 can be electrically connected to the SCL signal terminal of the focus driver chip 232 via the focus circuit board 231. The output end 282b of the second trace 282 can be exposed relative to the top surface of the anti-shake carrier 12 and spaced apart from the output end 281b of the first trace 281. It will be understood that the SCL signal terminal can be used to transmit the serial clock (SCL) signal of the I2C signal.
[0195] For example, the input end 283a of the third trace 283 can be exposed relative to the top surface of the anti-shake carrier 12. The input end 283a of the third trace 283 can be electrically connected to the positive power supply terminal of the focus driver chip 232 via the focus circuit board 231. The output end 283b of the third trace 283 can be exposed relative to the top surface of the anti-shake carrier 12 and spaced apart from the output end 281b of the first trace 281 and the output end 282b of the second trace 282.
[0196] For example, the input end 284a of the fourth trace 284 can be exposed relative to the top surface of the anti-shake carrier 12. The input end 284a of the fourth trace 284 can be electrically connected to the negative power supply terminal of the focus driver chip 232 via the focus circuit board 231. The output end 284b of the fourth trace 284 can be exposed relative to the top surface of the anti-shake carrier 12 and spaced apart from the output end 281b of the first trace 281, the output end 282b of the second trace 282, and the output end 283b of the third trace 283.
[0197] In other embodiments, the first trace 281, the second trace 282, the third trace 283, and the fourth trace 284 may each utilize a flexible circuit board structure. Alternatively, the first trace 281, the second trace 282, the third trace 283, and the fourth trace 284 may be integrated into a single flexible circuit board. This will be described in detail below with reference to the accompanying drawings.
[0198] FIG23 is a partial structural diagram of an embodiment of the motor 1 shown in FIG4 .
[0199] As shown in Figures 21 to 23, the first conductive spring 285, the second conductive spring 286, the third conductive spring 287, and the fourth conductive spring 288 can all be made of metal spring structures. The first conductive spring 285, the second conductive spring 286, the third conductive spring 287, and the fourth conductive spring 288 can all deform under stress, that is, have a stretchable effect.
[0200] For example, multiple conductive springs 28b are fixed to the anti-shake carrier 12 at intervals. For example, the first conductive spring 285, the second conductive spring 286, the third conductive spring 287, and the fourth conductive spring 288 can all be disposed on the top surface of the anti-shake carrier 12. It is understood that the first conductive spring 285, the second conductive spring 286, the third conductive spring 287, and the fourth conductive spring 288 can utilize the dimensions of the XY plane of the motor 1. This allows the first conductive spring 285, the second conductive spring 286, the third conductive spring 287, and the fourth conductive spring 288 to be disposed over a larger area, thereby achieving a smaller motion reaction force. It is understood that when the anti-shake carrier 12 moves relative to the base 11 in the XY plane, the first conductive spring 285, the second conductive spring 286, the third conductive spring 287, and the fourth conductive spring 288 deform, generating an elastic force. When the elastic force is opposite to the direction of motion, it acts as a motion reaction force. In this way, by increasing the area of the first conductive spring 285, the second conductive spring 286, the third conductive spring 287, and the fourth conductive spring 288, the length of the first conductive spring 285, the second conductive spring 286, the third conductive spring 287, and the fourth conductive spring 288 is increased, thereby reducing the elastic force of the first conductive spring 285, the second conductive spring 286, the third conductive spring 287, and the fourth conductive spring 288, that is, reducing the motion reaction force. If the motion reaction force of the conductive spring 28b is mentioned below, please refer to the explanation of the motion reaction force of the first conductive spring 285, the second conductive spring 286, the third conductive spring 287, and the fourth conductive spring 288, and the details will not be repeated here.
[0201] In other embodiments, the first conductive spring 285 , the second conductive spring 286 , the third conductive spring 287 and the fourth conductive spring 288 may also be disposed on the peripheral side of the anti-shake carrier 12 .
[0202] For example, the input ends of the plurality of conductive springs 28b are electrically connected to the output ends of the plurality of traces 28a in a one-to-one correspondence. At this point, the input ends of the plurality of conductive springs 28b are electrically connected to the plurality of ports of the focus driver chip 232 in a one-to-one correspondence through the plurality of traces 28a and the focus circuit board 231.
[0203] It is understood that the input end 285a of the first conductive spring 285 is electrically connected to the output end 281b of the first trace 281. In this case, the first conductive spring 285 can be electrically connected to the SDA signal terminal of the focus driver chip 232 via the first trace 281 and the focus circuit board 231. The input end 286a of the second conductive spring 286 is electrically connected to the output end 282b of the second trace 282. In this case, the second conductive spring 286 can be electrically connected to the SCL signal terminal of the focus driver chip 232 via the second trace 282 and the focus circuit board 231. The input end 287a of the third conductive spring 287 is electrically connected to the output end 283b of the third trace 283. In this case, the third conductive spring 287 can be electrically connected to the positive power supply terminal of the focus driver chip 232 via the third trace 283 and the focus circuit board 231. The input end 288a of the fourth conductive spring 288 is electrically connected to the output end 284b of the fourth trace 284. At this time, the fourth conductive spring 288 can be electrically connected to the negative power terminal of the focus driving chip 232 through the fourth trace 284 and the focus circuit board 231 .
[0204] In one embodiment, the input end 285a of the first conductive spring 285 can be fixedly connected to the output end 281b of the first trace 281 by welding or conductive adhesive. The connection method between the input end 286a of the second conductive spring 286 and the output end 282b of the second trace 282, the connection method between the input end 287a of the third conductive spring 287 and the output end 283b of the third trace 283, and the connection method between the input end 288a of the fourth conductive spring 288 and the output end 284b of the fourth trace 284 can all refer to the connection method between the input end 285a of the first conductive spring 285 and the output end 281b of the first trace 281. The details will not be repeated here.
[0205] As shown in FIG. 20 to FIG. 23 , the outgoing ends of the plurality of conductive springs 28 b are electrically connected to the plurality of connection terminals 50 in a one-to-one correspondence.
[0206] Illustratively, the outgoing end 285b of the first conductive spring 285 is electrically connected to the incoming end 561 of the first terminal 56. The outgoing end 286b of the second conductive spring 286 is electrically connected to the incoming end 571 of the second terminal 57. The outgoing end 287b of the third conductive spring 287 is electrically connected to the incoming end 581 of the third terminal 58. The outgoing end 288b of the fourth conductive spring 288 is electrically connected to the incoming end 591 of the fourth terminal 59.
[0207] In one embodiment, the outgoing end 285b of the first conductive spring 285 can be fixedly connected to the incoming end 561 of the first terminal 56 by welding or conductive adhesive. The connection method between the outgoing end 286b of the second conductive spring 286 and the incoming end 571 of the second terminal 57, the connection method between the outgoing end 287b of the third conductive spring 287 and the incoming end 581 of the third terminal 58, and the connection method between the outgoing end 288b of the fourth conductive spring 288 and the incoming end 591 of the fourth terminal 59 can all refer to the connection method between the outgoing end 285b of the first conductive spring 285 and the incoming end 561 of the first terminal 56. Details will not be repeated here.
[0208] It can be understood that, since the input end 281a of the first trace 281 can be electrically connected to the SDA signal end of the focus driver chip 232 through the focus circuit board 231, the input end 285a of the first conductive spring 285 is electrically connected to the output end 281b of the first trace 281, the output end 285b of the first conductive spring 285 is electrically connected to the input end 561 of the first wiring terminal 56, and the output end 562 of the first wiring terminal 56 is electrically connected to the module circuit board 4, an external power supply can input a signal to the SDA signal end of the focus driver chip 232 through the module circuit board 4, the first wiring terminal 56, the first conductive spring 285, the first trace 281, and the focus circuit board 231. Similarly, the external power supply can input a signal to the SCL signal end of the focus driver chip 232 through the module circuit board 4, the second wiring terminal 57, the second conductive spring 286, the second trace 282, and the focus circuit board 231. In addition, the external power supply can be electrically connected to the positive power terminal of the focus driver chip 232 through the module circuit board 4, the third terminal 58, the third conductive spring 287, the third trace 283, and the focus circuit board 231. The external power supply can be electrically connected to the negative power terminal of the focus driver chip 232 through the module circuit board 4, the fourth terminal 59, the fourth conductive spring 288, the fourth trace 284, and the focus circuit board 231.
[0209] It is understandable that in this embodiment, since the anti-shake carrier 12 can move in any direction in the XY plane relative to the base 11, the distance between the anti-shake carrier 12 and the base 11 will change during the anti-shake process. Therefore, this embodiment provides a first conductive spring 285 with elastic force to connect the first terminal 56 of the base 11 and the first trace 281 of the anti-shake carrier 12, so that when the distance between the anti-shake carrier 12 and the base 11 changes, the stretching of the first conductive spring 285 is used to offset this part of the distance change to ensure that the line is not easily disconnected, that is, to improve the stability of the circuit. Similarly, the second conductive spring 286, the second conductive spring 286 and the fourth conductive spring 288 all have similar functions. The details will not be repeated here.
[0210] FIG. 24 is a schematic structural diagram of another embodiment of a circuit in which the focus driving chip 232 shown in FIG. 5 is electrically connected to an external structure.
[0211] As shown in FIG23 and FIG24 , the variable aperture 3 includes a plurality of conductive reeds 36 a , including a first conductive reed 361 , a second conductive reed 362 , a third conductive reed 363 , and a fourth conductive reed 364 .
[0212] For example, the first conductive spring 361, the second conductive spring 362, the third conductive spring 363, and the fourth conductive spring 364 can all be metal spring structures. The first conductive spring 361, the second conductive spring 362, the third conductive spring 363, and the fourth conductive spring 364 can all deform under stress, that is, have a stretchable effect.
[0213] Exemplarily, the plurality of conductive reeds 36a are fixed at intervals on the focusing carrier 21. For example, the first conductive reed 361, the second conductive reed 362, the third conductive reed 363 and the fourth conductive reed 364 can be arranged at intervals on the top surface of the focusing carrier 21.
[0214] Exemplarily, the access ends of the plurality of conductive springs 36 a are used to electrically connect to a plurality of ports of the driving chip 31 of the variable aperture 3 in a one-to-one correspondence.
[0215] It will be appreciated that the access end 3611 of the first conductive reed 361 can be electrically connected to the SDA signal terminal of the driver chip 31 of the variable aperture 3. In one embodiment, the access end 3611 of the first conductive reed 361 can be electrically connected to the SDA signal terminal of the driver chip 31 of the variable aperture 3 via a circuit board and wiring terminals of the variable aperture 3. It will be appreciated that FIG24 schematically illustrates the driver chip 31 of the variable aperture 3 using dashed lines. The actual shape, size, position, and structure of the driver chip 31 are not limited by FIG24 or the following figures.
[0216] It is understood that the access end 3621 of the second conductive spring 362 can be electrically connected to the SCL signal end of the driver chip 31 of the variable aperture 3. In one embodiment, the access end 3621 of the second conductive spring 362 can be electrically connected to the SCL signal end of the driver chip 31 of the variable aperture 3 through a circuit board and a terminal block of the variable aperture 3.
[0217] It is understood that the access end 3631 of the third conductive spring 363 can be electrically connected to the positive power terminal of the driver chip 31 of the variable aperture 3. In one embodiment, the access end 3631 of the third conductive spring 363 can be electrically connected to the negative power terminal of the driver chip 31 of the variable aperture 3 through a circuit board and a terminal block of the variable aperture 3.
[0218] It is understood that the access end 3641 of the fourth conductive spring 364 can be electrically connected to the negative power supply terminal of the driver chip 31 of the variable aperture 3. In one embodiment, the access end 3641 of the fourth conductive spring 364 can be electrically connected to the negative power supply terminal of the driver chip 31 of the variable aperture 3 through a circuit board and a terminal block of the variable aperture 3.
[0219] As shown in Figures 23 and 24, the connecting ends of the plurality of conductive springs 36a are electrically connected to the plurality of wires 28a in a one-to-one correspondence. At this time, the connecting ends of the plurality of conductive springs 36a are electrically connected to the plurality of conductive springs 28b in a one-to-one correspondence via the plurality of wires 28a.
[0220] It is understood that the connection end 3612 of the first conductive spring 361 is electrically connected to the first trace 281. For example, a portion of the middle portion of the first trace 281 may be exposed relative to the top surface of the anti-shake carrier 12. The connection end 3612 of the first conductive spring 361 is fixedly connected to the middle portion of the first trace 281 by welding or conductive adhesive. Of course, in other embodiments, the connection end 3612 of the first conductive spring 361 may also be electrically connected to the first trace 281 by other means, and the location of the electrical connection is not specifically limited.
[0221] It is understood that the connection method between the output terminal 3622 of the second conductive spring 362 and the second trace 282, the connection method between the output terminal 3632 of the third conductive spring 363 and the third trace 283, and the connection method between the output terminal 3642 of the fourth conductive spring 364 and the fourth trace 284 can all refer to the connection method between the input terminal 3611 of the first conductive spring 361 and the first trace 281. Detailed description is omitted here.
[0222] It can be understood that since the input end 3611 of the first conductive spring 361 can be electrically connected to the SDA signal terminal of the driver chip 31 of the variable aperture 3, the output end 3612 of the first conductive spring 361 is electrically connected to the first trace 281, the input end 285a of the first conductive spring 285 is electrically connected to the output end 281b of the first trace 281, the output end 285b of the first conductive spring 285 is electrically connected to the input end 561 of the first wiring terminal 56, and the output end 562 of the first wiring terminal 56 is electrically connected to the module circuit board 4, an external power supply can input a signal to the SDA signal terminal of the driver chip 31 of the variable aperture 3 through the module circuit board 4, the first wiring terminal 56, the first conductive spring 285, the first trace 281, and the first conductive spring 361. Similarly, an external power source can input a signal to the SCL signal terminal of the driver chip 31 of the variable aperture 3 via the module circuit board 4, the second terminal 57, the second conductive spring 286, the second trace 282, and the second conductive spring 362. Furthermore, the external power source can be connected to the positive power terminal of the driver chip 31 of the variable aperture 3 via the module circuit board 4, the third terminal 58, the third conductive spring 287, the third trace 283, and the third conductive spring 363. The external power source can be electrically connected to the negative power terminal of the driver chip 31 of the variable aperture 3 via the module circuit board 4, the third terminal 58, the third conductive spring 287, the third trace 283, and the fourth conductive spring 364.
[0223] It is understandable that the SDA signal line of the variable aperture 3 driver chip 31, the SCL signal line of the variable aperture 3 driver chip 31, the positive power line of the variable aperture 3 driver chip 31, and the negative power line of the variable aperture 3 driver chip 31 reuse the SDA signal line of the focus driver chip 232, the SCL signal line of the focus driver chip 232, the positive power line of the focus driver chip 232, and the negative power line of the focus driver chip 232. In this way, the circuit layout of the motor 1 is further simplified, and the structure of the motor 1 is also simpler.
[0224] It is understandable that in this embodiment, since the focusing carrier 21 can move in the Z-axis direction relative to the anti-shake carrier 12, the distance between the focusing carrier 21 and the anti-shake carrier 12 will change during the focusing process. Therefore, this embodiment provides a first conductive spring 361 with elastic force to connect the variable aperture 3 of the focusing carrier 21 and the first trace 281 of the anti-shake carrier 12. When the distance between the focusing carrier 21 and the anti-shake carrier 12 changes, the stretching of the first conductive spring 361 is used to offset this distance change, thereby ensuring that the circuit is not easily disconnected, that is, improving the stability of the circuit. Similarly, the second conductive spring 362, the second conductive spring 362, and the fourth conductive spring 364 also have similar functions. The details will not be repeated here.
[0225] The above describes one embodiment of the circuit configuration of the focus driver chip 232 and the driver chip 31 of the variable aperture 3 in conjunction with the relevant drawings. The following describes the operation of the focus driver chip 232 and the driver chip 31 of the variable aperture 3 in conjunction with the relevant drawings.
[0226] FIG. 25 is a schematic diagram of an embodiment of the electrical connection relationship among the controller 8 of the motor 1 , the focus driving chip 232 , and the driving chip 31 of the variable aperture 3 shown in FIG. 4 .
[0227] As shown in FIG25 , the camera module 100 includes a controller 8. The controller 8 can be fixed to and electrically connected to the module circuit board 4 (see FIG19 ). The controller 8 is communicatively coupled to the focus driver chip 232. The controller 8 is also communicatively coupled to the driver chip 31 for the variable aperture 3. For example, the controller 8 can control the operation of the focus driver chip 232 and the driver chip 31 for the variable aperture 3 through address control.
[0228] As shown in FIG25 , when the camera module 100 needs to enter the focus state, the controller 8 controls the focus driver chip 232 to be in an active state and simultaneously controls the driver chip 31 of the variable aperture 3 to be in an inactive state (for example, the driver chip 31 of the variable aperture 3 cannot form a current loop). As shown in FIG20 to FIG22 , the SDA signal can be transmitted to the SDA signal terminal of the focus driver chip 232 via the module circuit board 4, the first terminal 56, the first conductive spring 285, the first trace 281, and the focus circuit board 231. In addition, the SCL signal can be transmitted to the SCL signal terminal of the focus driver chip 232 via the module circuit board 4, the second terminal 57, the second conductive spring 286, the second trace 282, and the focus circuit board 231. In addition, the external power supply can power the focus driver chip 232 through the module circuit board 4, the third terminal 58, the third conductive spring 287, the third trace 283, the fourth terminal 59, the fourth conductive spring 288, the fourth trace 284 and the focus circuit board 231.
[0229] As shown in FIG25 , when the camera module 100 needs to enter the aperture adjustment state, the controller 8 controls the focus driver chip 232 to be in an inactive state (e.g., the focus driver chip 232 cannot form a current loop) and simultaneously controls the driver chip 31 of the variable aperture 3 to be in an active state. As shown in FIG20 to FIG24 , the SDA signal can be transmitted to the SDA signal terminal of the driver chip 31 of the variable aperture 3 via the module circuit board 4, the first terminal 56, the first conductive spring 285, the first trace 281, and the first conductive reed 361. Furthermore, the SCL signal can be transmitted to the SCL signal terminal of the driver chip 31 of the variable aperture 3 via the module circuit board 4, the second terminal 57, the second conductive spring 286, the second trace 282, and the second conductive reed 362. In addition, the external power supply can power the driver chip 31 of the variable aperture 3 through the module circuit board 4, the third terminal 58, the third conductive spring 287, the third trace 283, the third conductive spring 363, the fourth terminal 59, the fourth conductive spring 288, the fourth trace 284 and the fourth conductive spring 364.
[0230] The above describes one embodiment of the circuit configuration of the focus driver chip 232 and the driver chip 31 of the variable aperture 3 in conjunction with the relevant drawings. The following describes another embodiment of the circuit configuration of the focus driver chip 232 and the driver chip 31 of the variable aperture 3 in conjunction with the relevant drawings.
[0231] Figure 26 is a partially exploded schematic diagram of another embodiment of the camera module 100 shown in Figure 3. Figure 27 is a partially exploded schematic diagram of another embodiment of the motor 1 shown in Figure 26. Figure 28 is a partial structural schematic diagram of another embodiment of the camera module 100 shown in Figure 3.
[0232] As shown in Figures 26 to 28, the focus driver module 20 further includes a first flexible circuit board 24. The first flexible circuit board 24 is electrically connected between the focus circuit board 231 and the module circuit board 4. Multiple ports of the focus driver chip 232 can be electrically connected to the module circuit board 4 via the focus circuit board 231 and the first flexible circuit board 24.
[0233] It is understood that when the camera module 100 needs to enter the focus state, the controller 8 controls the focus driver chip 232 to be in an active state and simultaneously controls the driver chip 31 of the variable aperture 3 to be in an inactive state (for example, the driver chip 31 of the variable aperture 3 cannot form a current loop). In this way, the SDA signal can be transmitted to the SDA signal terminal of the focus driver chip 232 via the module circuit board 4, the first flexible circuit board 24, and the focus circuit board 231. In addition, the SCL signal can be transmitted to the SCL signal terminal of the focus driver chip 232 via the module circuit board 4, the first flexible circuit board 24, and the focus circuit board 231. In addition, an external power supply can power the focus driver chip 232 via the module circuit board 4, the first flexible circuit board 24, and the focus circuit board 231.
[0234] In one embodiment, a portion of the first flexible circuit board 24 may be located between the fourth side 124 of the anti-shake carrier 12 and the base 11. That is, the first flexible circuit board 24 is located in a non-magnetic space, thereby reducing the impact on the magnetic components of the motor 1. In other embodiments, the location of the first flexible circuit board 24 is not specifically limited.
[0235] In one embodiment, the first flexible circuit board 24 can also be positioned within the length space surrounding the anti-shake carrier 12, thereby providing the first flexible circuit board 24 with a longer cantilever and thereby reducing the motion reaction force. It will be appreciated that when the anti-shake carrier 12 moves relative to the base 11 in the XY plane, the first flexible circuit board 24 bends or deforms, generating a force in the opposite direction, i.e., the motion reaction force. In this way, by increasing the length of the first flexible circuit board 24, the motion reaction force of the first flexible circuit board 24 is reduced. If any discussion regarding the motion reaction force of the first flexible circuit board 24 is discussed below, please refer to the explanation of the motion reaction force of the first flexible circuit board 24; the details will not be repeated here.
[0236] As shown in Figures 26 to 28 , the iris diaphragm 3 also includes a second flexible circuit board 32. One end of the second flexible circuit board 32 is electrically connected to multiple ports of the driver chip 31 of the iris diaphragm 3, and the other end is electrically connected to the first flexible circuit board 24. In this way, the multiple ports of the driver chip 31 of the iris diaphragm 3 can be electrically connected to the module circuit board 4 via the second flexible circuit board 32 and the first flexible circuit board 24.
[0237] It is understood that in this embodiment, the second flexible circuit board 32 can be integrally formed with the first flexible circuit board 24. In other embodiments, the second flexible circuit board 32 and the first flexible circuit board 24 can be two separate circuit boards. The two separate circuit boards are then electrically connected via an electrical connector.
[0238] It is understood that when the camera module 100 needs to enter the aperture adjustment state, the controller 8 controls the focus driver chip 232 to be inactive (for example, the focus driver chip 232 cannot form a current loop) and simultaneously controls the driver chip 31 of the variable aperture 3 to be active. In this way, the SDA signal can be transmitted to the SDA signal terminal of the driver chip 31 of the variable aperture 3 via the module circuit board 4, the first flexible circuit board 24, and the second flexible circuit board 32. Furthermore, the SCL signal can be transmitted to the SCL signal terminal of the driver chip 31 of the variable aperture 3 via the module circuit board 4, the first flexible circuit board 24, and the second flexible circuit board 32. Furthermore, an external power supply can power the driver chip 31 of the variable aperture 3 via the module circuit board 4, the first flexible circuit board 24, and the second flexible circuit board 32.
[0239] It is understandable that the SDA signal line of the variable aperture 3 driver chip 31, the SCL signal line of the variable aperture 3 driver chip 31, the positive power line of the variable aperture 3 driver chip 31, and the negative power line of the variable aperture 3 driver chip 31 reuse the SDA signal line of the focus driver chip 232, the SCL signal line of the focus driver chip 232, the positive power line of the focus driver chip 232, and the negative power line of the focus driver chip 232. In this way, the circuit layout of the motor 1 is further simplified, and the structure of the motor 1 is also simpler.
[0240] As shown in Figure 22, the second flexible circuit board 32 includes a first section 321, a second section 322, and a third section 323. The second section 322 is connected between the first section 321 and the third section 323. The first section 321 and the third section 323 are arranged opposite each other. The second section 322 is bent. Thus, the second flexible circuit board 32 is bent up and down. The first section 321 is electrically connected to multiple ports of the driver chip 31 of the variable aperture 3. The third section 323 is electrically connected to the first flexible circuit board 24 via the focusing circuit board 231.
[0241] As can be understood, by folding the second flexible circuit board 32 up and down, any changes in the distance between the focus support 21 and the anti-shake support 12 are offset by the second flexible circuit board 32's bendability, ensuring that the circuit is less likely to break, thereby improving circuit stability. Furthermore, this also minimizes the reaction force of the second flexible circuit board 32's movement.
[0242] In one embodiment, the second flexible circuit board 32 is located on top of the motor 1, with its projection on the motor 1 offset from the focus magnet. In other words, the second flexible circuit board 32 utilizes the non-magnetic space on top of the motor 1, thereby minimizing the impact on the focus magnet of the motor 1. In other embodiments, the location of the second flexible circuit board 32 is not specifically limited.
[0243] It is understandable that this embodiment introduces several circuit configurations. In other embodiments, the circuit configurations of the focus driver chip 232 and the driver chip 31 of the variable aperture 3 are not specifically limited.
[0244] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the scope of protection of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.
[0245] It should be noted that all the above drawings are for illustrative purposes only and do not represent the actual size of the product. Furthermore, the dimensional ratios between the components in the drawings are not intended to limit the actual product of the present application.
[0246] The above are only some of the embodiments and implementations of this application. The scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application.
