Description

Technical Field

[0001] 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

[0002] In recent years, with the rapid development of smart phones and people's high-end demand for mobile phone camera functions, camera modules with clear image quality, variable aperture, lightness and reliability have become product trends. The motor of a traditional camera module is assembled from two independently moving structural parts: the variable aperture and the focus motor. In the preparation process of the motor of a traditional camera module, the variable aperture and the focus motor must first be prepared separately, and then the variable aperture and the focus motor must be sent to the module factory for assembly. At this time, the variable aperture must be positioned and calibrated, and finally welded to the focus motor. This assembly process is complex and costly. Summary of the invention

[0003] The purpose of the present application is to provide a motor, a camera module and an electronic device with a simple assembly process and low cost.

[0004] In a first aspect, the present application provides a motor. The motor includes a base, a first carrier, a focus drive mechanism, a second carrier, a plurality of blades, and an aperture drive mechanism;

[0005] The first carrier is movably connected to the base, and the first carrier has an installation space, and the installation space is used to install the lens; the focus driving mechanism is used to drive the first carrier to move relative to the base along the optical axis direction of the lens; the second carrier is movably connected to the first carrier; the blades connect the first carrier and the second carrier, and the plurality of blades together surround an aperture hole, and the aperture hole is connected to the installation space;

[0006] The aperture driving mechanism is used to drive the second carrier to move relative to the first carrier, and the second carrier drives the multiple blades to move, so that the apertures of the aperture holes of the multiple blades change.

[0007] It is understandable that the present application sets up a motor structure that integrates the focus module and the variable aperture module. Among them, the focus module may include a base, a first carrier and a focus drive mechanism. The variable aperture module may include a second carrier, a plurality of blades and an aperture drive mechanism. Specifically, the first carrier of the present application can be used to install the lens to drive the lens to move along the optical axis direction of the lens under the driving force of the focus drive mechanism, thereby realizing automatic focusing; it can also be used to connect the blades to cooperate with the second carrier, so that the second carrier drives the opening and closing of the plurality of blades under the driving force of the aperture drive mechanism, and the aperture of the aperture holes of the plurality of blades can be enlarged or reduced. In this way, the variable aperture module can be used to adjust the amount of light entering, so that the camera module can maintain a constant shooting quality under various brightness conditions. The integrated motor of the focus and variable aperture of the present application has a relatively compact structure and a high space utilization rate.

[0008] It is understandable that the traditional motor is assembled from two independent structural parts, the variable aperture and the focus motor. During the preparation process of the motor, the variable aperture and the focus motor need to be prepared separately first, and then the variable aperture and the focus motor are sent to the module factory for assembly. At this time, the variable aperture needs to be positioned and calibrated, and finally it is welded to the focus motor. This assembly process is complicated and costly. In the present application, the focus module and the variable aperture module are integrated into one to form a motor with an integrated structure. On the one hand, the motor is smaller in size, which is conducive to the miniaturization of the motor, thereby saving the internal space of the electronic device. On the other hand, the motor of the present application no longer needs to prepare the variable aperture and the focus motor separately, and then send them to the module factory for calibration and assembly. The motor of the present application can simplify the assembly process and reduce cost investment.

[0009] It is understandable that the drive of the variable aperture module of the motor of the present application is controlled solely by the aperture drive mechanism. Among them, the second carrier of the motor rotates relative to the first carrier, that is, during the process of adjusting the aperture size, the relative position of the first carrier and the base is not affected. Similarly, the drive of the focus module of the motor of the present application in the direction of the optical axis is controlled solely by the focus drive mechanism. Among them, the first carrier of the motor moves along the optical axis relative to the base, that is, during the process of automatic focusing, the relative position of the first carrier and the second carrier is not affected. Therefore, the focus drive mechanism and the aperture drive mechanism of the motor are decoupled and do not interfere with each other during movement, which is conducive to ensuring the driving accuracy of the motor.

[0010] In a possible implementation, the first carrier includes a first mounting portion and a second mounting portion, the second mounting portion is convexly disposed on the top surface of the first mounting portion, the first mounting portion and the second mounting portion are both annular, the inner space of the first mounting portion is used to mount the tail of the lens, and the inner space of the second mounting portion is used to mount the head of the lens;

[0011] The first mounting part is movably connected to the base; the second carrier is movably connected to the second mounting part; the blades connect the second mounting part and the second carrier, the plurality of blades are located on a side of the second mounting part away from the first mounting part, and the aperture hole is connected to the inner space of the second mounting part.

[0012] It can be understood that the present implementation provides a structure of a first carrier. The tail of the lens is installed through the inner space of the first mounting portion of the first carrier, and the head of the lens is installed through the inner space of the second mounting portion, so that the lens is installed in the first carrier. In this way, under the driving force of the focus drive mechanism, the first carrier can drive the lens to move along the optical axis direction of the lens, thereby achieving automatic focus. In addition, by locating a plurality of blades on the side of the second mounting portion away from the first mounting portion, the aperture hole is connected to the inner space of the second mounting portion. In this way, under the driving force of the aperture drive mechanism, the second carrier can drive the plurality of blades to open and close, and the aperture of the aperture holes of the plurality of blades can be enlarged or reduced. At this time, the aperture hole can adjust the luminous flux entering the mounting space of the first carrier, and then adjust the luminous flux entering the lens.

[0013] It can be understood that the base, the first carrier, the second carrier, and the multiple blades of the present implementation are arranged compactly, and the first carrier has the effect of "one object for multiple uses". Therefore, the space utilization rate of the motor of the present implementation is high, which is conducive to simplifying the structure of the motor.

[0014] In a possible implementation, the second mounting portion includes a first sub-mounting portion and a plurality of second sub-mounting portions, the first sub-mounting portion is convexly arranged on the top surface of the first mounting portion, the plurality of second sub-mounting portions are arranged around the first sub-mounting portion, and the first sub-mounting portion is ring-shaped;

[0015] The second carrier is annular, at least part of the second carrier is located between the first sub-mounting portion and the second sub-mounting portion, the second carrier is arranged around the first sub-mounting portion, and the second carrier is rotatably connected to the first sub-mounting portion or the second sub-mounting portion;

[0016] The blades connect the first sub-mounting portion and the second carrier, and the plurality of blades are located at a side of the first sub-mounting portion away from the first mounting portion.

[0017] It is understandable that the present implementation provides a structure of a second mounting portion. The inner space of the first sub-mounting portion can be used to mount the head of the lens. In addition, the first sub-mounting portion can also be used to connect the blades to cooperate with the second carrier, so that the second carrier can drive the plurality of blades to open and close under the driving force of the aperture drive mechanism, and the aperture of the plurality of blades can be enlarged or reduced. The first sub-mounting portion has the effect of "one object for multiple uses".

[0018] In addition, by setting up multiple second sub-mounting parts, and the multiple second sub-mounting parts are set around the first sub-mounting part, at least a portion of the second carrier is located between the first sub-mounting part and the second sub-mounting part, and the second carrier is set around the first sub-mounting part. At this time, the first carrier and the second carrier are arranged compactly, which is beneficial to improving the space utilization of the motor.

[0019] In a possible implementation, the blade is slidably connected to the second mounting portion, and the blade is rotationally connected to the second carrier; or, the blade is rotationally connected to the second mounting portion, and the blade is slidably connected to the second carrier.

[0020] It can be understood that the connection method between the blade and the first carrier and the second carrier is relatively simple.

[0021] In a possible implementation manner, the second carrier is rotatably connected to the second mounting portion via a rolling element or a sliding shaft.

[0022] It is understandable that the second carrier is rotatably connected to the first carrier via a rolling element or a sliding shaft, so that the friction coefficient of the second carrier relative to the first carrier is smaller, which is conducive to reducing the wear between the second carrier and the first carrier to a greater extent.

[0023] In a possible implementation, the motor further includes an upper cover, which is fixed on the second mounting portion, and the upper cover is located on a side of the plurality of blades away from the second carrier.

[0024] It can be understood that, in the direction of the optical axis, the upper cover can limit the plurality of blades, thereby preventing the plurality of blades from falling out.

[0025] In a possible implementation, the second carrier includes a main body and a first extension portion, wherein the first extension portion is connected to the main body and extends in a direction away from the center of the main body;

[0026] The main body is annular, and is disposed around the second mounting portion and is rotatably connected to the second mounting portion, and the first extension portion is disposed opposite to the top surface of the first mounting portion;

[0027] The aperture driving mechanism includes a first aperture coil and a first aperture magnetic member;

[0028] One of the first aperture magnetic component and the first aperture coil is fixed on the first mounting portion, and the other is fixed on the first extending portion, and the first aperture coil faces the first aperture magnetic component.

[0029] It is understandable that the main body of the second carrier can be used to connect the blades to cooperate with the second carrier, so that the second carrier can drive the multiple blades to open and close under the driving force of the aperture drive mechanism, and the aperture of the multiple blades can be enlarged or reduced. In addition, the first extension of the second carrier can be used to install one of the first aperture coil and the first aperture magnetic member of the aperture drive mechanism. The second carrier has the effect of "one object for multiple uses".

[0030] In a possible implementation, the second carrier further includes a second extension portion, the second extension portion is connected to the main body portion and extends in a direction away from the center of the main body portion, the second extension portion is spaced apart from the first extension portion, and the second extension portion is disposed opposite to a top surface of the first mounting portion;

[0031] The aperture driving mechanism includes a second aperture coil and a second aperture magnetic member;

[0032] One of the second aperture magnetic member and the second aperture coil is fixed to the first mounting portion, and the other is fixed to the second extending portion, and the second aperture coil faces the second aperture magnetic member.

[0033] It can be understood that the aperture driving mechanism includes a structure of two groups of magnetic parts and coils, which can greatly improve the driving force of the aperture driving mechanism.

[0034] In a possible implementation, the second aperture coil is connected in series or in parallel with the first aperture coil through the conductive member in the second carrier. In this way, the electrical connection path between the second aperture coil and the first aperture coil can largely utilize the space of the second carrier, thereby greatly improving the space utilization of the motor. In addition, since the conductive member in the second carrier is embedded in the second carrier, the electrical connection path between the second aperture coil and the first aperture coil can avoid interference from internal components of the motor.

[0035] In a possible implementation, the second carrier includes a main body and a first extension portion, wherein the first extension portion is connected to the main body and extends in a direction away from the center of the main body;

[0036] The main body is annular, and is disposed around the first sub-mounting portion and is rotatably connected to the first sub-mounting portion or the second sub-mounting portion. A portion of the first extension portion passes through the space between two adjacent second sub-mounting portions and is disposed opposite to the top surface of the first mounting portion.

[0037] The aperture driving mechanism includes a first aperture coil and a first aperture magnetic member;

[0038] One of the first aperture magnetic component and the first aperture coil is fixed on the first mounting portion, and the other is fixed on the first extending portion, and the first aperture coil faces the first aperture magnetic component.

[0039] It is understandable that the main body of the second carrier can be used to connect the blades to cooperate with the second carrier, so that the second carrier can drive the multiple blades to open and close under the driving force of the aperture drive mechanism, and the aperture of the multiple blades can be enlarged or reduced. In addition, the first extension portion of the second carrier can be used to install one of the first aperture coil and the first aperture magnetic member of the aperture drive mechanism. The second carrier has the effect of "one object for multiple uses".

[0040] In addition, the main body of the second carrier, the first extension portion and the second mounting portion of the first carrier are arranged compactly, which is beneficial to improving space utilization.

[0041] In a possible implementation, the second carrier further includes a second extension portion, the second extension portion is connected to the main body portion and extends in a direction away from the center of the main body portion, the second extension portion is spaced apart from the first extension portion, a portion of the second extension portion passes through a space between two adjacent second sub-mounting portions, and is disposed opposite to a top surface of the first mounting portion;

[0042] The aperture driving mechanism includes a second aperture coil and a second aperture magnetic member;

[0043] One of the second aperture magnetic member and the second aperture coil is fixed to the first mounting portion, and the other is fixed to the second extending portion, and the second aperture coil faces the second aperture magnetic member.

[0044] It is understandable that the aperture drive mechanism includes a structure of two sets of magnetic parts and coils, which can greatly improve the driving force of the aperture drive mechanism. In addition, the main body of the second carrier, the first extension part, the second extension part and the second mounting part of the first carrier are arranged more compactly, which is conducive to improving space utilization.

[0045] In one possible implementation, the motor further includes a flexible circuit board and an aperture driving chip;

[0046] The first aperture coil and the aperture driving chip are both fixed on the flexible circuit board and electrically connected to the flexible circuit board. The input end and the output end of the first aperture coil form a current loop through the flexible circuit board and the aperture driving chip.

[0047] In a possible implementation, the flexible circuit board includes a first end portion, a middle portion, and a second end portion connected in sequence;

[0048] The first aperture coil and the aperture driving chip are both fixed on the first end of the flexible circuit board;

[0049] The first end of the flexible circuit board is fixed on the first extension portion of the second carrier, the middle portion of the flexible circuit board is arranged around the first sub-mounting portion, and the second end of the flexible circuit board is fixed on the second sub-mounting portion;

[0050] The aperture driving chip is electrically connected to the conductive member of the first carrier through the flexible circuit board.

[0051] It is understandable that the variable aperture module of the motor of the present application adopts a dynamic coil setting, and the drive of the variable aperture module is controlled solely by the aperture drive mechanism. Among them, the second carrier of the motor rotates relative to the first carrier, that is, during the process of adjusting the aperture size, the relative position of the first carrier and the base is not affected. At this time, when the focus drive mechanism adopts a coil and magnetic part structure, the magnetic gap of the focus drive mechanism is not easy to change. Similarly, when the focus module adopts a dynamic magnet setting, the drive of the focus module in the optical axis direction is controlled solely by the focus drive mechanism. Among them, the first carrier of the motor moves along the optical axis relative to the base, that is, during the process of automatic focusing, the relative position of the first carrier and the second carrier is not affected, and the magnetic gap of the aperture drive mechanism of the variable aperture module is not easy to change. Therefore, the focus drive mechanism and the aperture drive mechanism of the motor are decoupled, and do not interfere with each other during movement, which is conducive to ensuring the driving accuracy of the motor.

[0052] It is understandable that the variable aperture module of the motor of the present application adopts a moving coil setting. At this time, the magnetic component of the variable aperture module is not easy to generate magnetic interference to the external magnetic component.

[0053] It is understandable that the aperture driving chip is electrically connected to the conductive member of the first carrier through the flexible circuit board. The flexible circuit board spans the space between the second carrier and the first carrier. Since the flexible circuit board has a certain degree of flexibility, it ensures that the current path of the aperture driving chip is not easily torn off or unreliable in connection during the movement of the second carrier relative to the first carrier. In this way, the reliability of the current path of the first aperture coil is better.

[0054] In a possible implementation, the motor further includes an elastic member, a first end of the elastic member is fixed on the second carrier and electrically connected to the conductive member in the second carrier, and a second end of the elastic member is fixed on the first carrier and electrically connected to the conductive member in the first carrier;

[0055] The aperture driving chip is electrically connected to the conductive member in the first carrier through the flexible circuit board, the conductive member in the second carrier and the elastic member.

[0056] It can be understood that the aperture drive chip is electrically connected to the conductive member in the first carrier through the flexible circuit board, the conductive member in the second carrier and the elastic member. The elastic member spans the space between the second carrier and the first carrier. Since the elastic member has a certain flexibility, it ensures that the current path of the aperture drive chip is not prone to tearing or unreliable connection during the movement of the second carrier relative to the first carrier. In this way, the reliability of the current path of the first aperture coil is better.

[0057] In one possible implementation, a first protrusion is protruding from the outer side surface of the main body, and the first protrusion is located between two adjacent second sub-mounting parts; when the aperture of the aperture hole is minimum, the first protrusion abuts against the first second sub-mounting part, and when the aperture of the aperture hole is maximum, the first protrusion abuts against the second second sub-mounting part.

[0058] It can be understood that when the second carrier rotates relative to the first carrier, the two second sub-mounting parts can stop the second carrier, that is, prevent the second carrier from deviating from the predetermined stroke.

[0059] In a possible implementation, a second protrusion is convexly provided on the bottom surface of the main body, and the second protrusion abuts against the second sub-mounting portion. In this way, in the Z-axis direction, the second sub-mounting portion of the first carrier can support the second carrier to ensure that the second carrier has better stability. In addition, the second protrusion can raise the height of the main body relative to the first carrier, thereby facilitating the freeing up space for the flexible circuit board to be arranged.

[0060] In a possible implementation, the focus drive mechanism includes a first focus coil and a first focus magnetic member;

[0061] The first focusing magnetic component is fixed on the first mounting portion, the first focusing coil is fixed on the base, and the first focusing coil faces the first focusing magnetic component.

[0062] It is understandable that the variable aperture module of the motor of the present application adopts a dynamic coil setting, and the drive of the variable aperture module is controlled solely by the aperture drive mechanism. Among them, the second carrier of the motor rotates relative to the first carrier, that is, during the process of adjusting the aperture size, the relative position of the first carrier and the base is not affected, and the magnetic gap of the focus drive mechanism is not easy to change. Similarly, the focus module of the motor of the present application adopts a dynamic magnet setting, and the drive of the focus module in the optical axis direction is controlled solely by the focus drive mechanism. Among them, the first carrier of the motor moves along the optical axis relative to the base, that is, during the process of automatic focusing, the relative position of the first carrier and the second carrier is not affected, and the magnetic gap of the aperture drive mechanism of the variable aperture module is not easy to change. Therefore, the focus drive mechanism and the aperture drive mechanism of the motor are decoupled, and do not interfere with each other during movement, which is conducive to ensuring the driving accuracy of the motor.

[0063] It can be understood that, in this embodiment, the first focusing magnetic component, the second focusing magnetic component, the first aperture magnetic component and the second aperture magnetic component are all fixed to the first carrier, so that during the focusing process of the motor and the aperture hole size adjustment process, the relative positions of the first focusing magnetic component, the second focusing magnetic component of the focusing module and the first aperture magnetic component, the second aperture magnetic component of the variable aperture module will not change. In this way, there is no coupling effect between the first focusing magnetic component, the second focusing magnetic component of the focusing module and the first aperture magnetic component, the second aperture magnetic component of the variable aperture module, that is, the first focusing magnetic component, the second focusing magnetic component of the focusing module will not generate magnetic interference with the first aperture magnetic component, the second aperture magnetic component of the variable aperture module. The first aperture magnetic component, the second aperture magnetic component of the variable aperture module will not generate magnetic interference with the first focusing magnetic component, the second focusing magnetic component of the focusing module.

[0064] In a possible implementation, the focus drive mechanism further includes a second focus coil and a second focus magnetic member;

[0065] The second focusing magnetic component is fixed on the first mounting portion and is located on a side of the first mounting portion away from the first focusing magnetic component. The second focusing coil is fixed on the base and faces the second focusing magnetic component.

[0066] It can be understood that the focus driving mechanism includes a structure of two groups of magnetic parts and coils, which can greatly improve the driving force of the focus driving mechanism.

[0067] In a possible implementation, the motor further includes a first support member, and the first carrier is movably connected to the base via the first support member;

[0068] The first supporting member includes a sliding shaft, a ball bearing or a spring.

[0069] It is understandable that the first support member is a sliding shaft, and the guiding direction of the sliding shaft is better, which is conducive to improving the accuracy of the movement of the first carrier relative to the base.

[0070] It is understandable that the first support member adopts a ball bearing. On the one hand, the contact area between the first carrier and the ball bearing is small, and the friction between the first carrier and the ball bearing is small, which is conducive to reducing motor loss; on the other hand, the cost of the ball bearing is low, which is conducive to reducing the cost investment of the motor.

[0071] It is understandable that the first support member adopts a reed structure. On the one hand, the reed can provide a restoring force to the first carrier, reducing the power consumption of the first carrier returning to its original position; on the other hand, the cost of the reed is relatively low, which is conducive to reducing the cost investment of the motor.

[0072] In a possible implementation, the first support member includes a sliding shaft, which is fixed on the base and is made of a magnetic conductive material;

[0073] The motor also includes a magnetic component, which is fixed on the first carrier and located around the sliding shaft. The magnetic component is used to generate magnetic attraction with the sliding shaft.

[0074] It can be understood that a magnetic attraction force can be generated between the magnetic part and the sliding shaft, which can adsorb the first carrier on the sliding shaft, so that the first carrier tends to approach the base, thereby ensuring that the first carrier is not easy to fall off the sliding shaft, and the first carrier and the sliding shaft can maintain contact, thereby further achieving pre-tightening.

[0075] In the second aspect, the present application provides a camera module. The camera module includes a lens, an image sensor, and a motor as described above, wherein the lens is installed in the installation space of the motor, and the image sensor is located on the light-emitting side of the lens. When the motor is applied to the camera module, the structure of the camera module is relatively compact and the space utilization rate is high. In addition, the assembly process of the camera module is relatively simple, which is conducive to reducing cost investment.

[0076] In a third aspect, the present application provides an electronic device. The electronic device includes a device housing and a camera module as described above, and the camera module is disposed in the device housing. When the camera module is applied to the electronic device, the structure of the electronic device is relatively compact and the space utilization rate is relatively high. In addition, the assembly process of the electronic device is relatively simple, which is conducive to reducing cost investment. BRIEF DESCRIPTION OF THE DRAWINGS

"Sliding connection" means that they are connected to each other and can slide relative to each other after connection. "Rotational connection" means that they are connected to each other and can rotate relative to each other after connection. Among them, "electrical connection" means that electrical signals can be conducted between each other. In addition, two components obtain an integrated structure through an integrated molding process, which means that in the process of forming one of the two components, the component is connected to the other component, and there is no need to connect the two components together through reprocessing (such as bonding, welding, snap connection, screw connection).

[0121] In addition, in the embodiments of the present application, the mathematical concepts mentioned are parallel, perpendicular, etc. These limitations are all for the current state of the art, rather than being absolutely strict definitions in a mathematical sense, and a small amount of deviation is allowed, and it is possible to be approximately parallel, approximately perpendicular, etc. 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.

[0122] Figure 1 It is a structural diagram of an electronic device 1000 provided in an embodiment of the present application.

[0123] like Figure 1As shown, in some embodiments, the electronic device 1000 can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses or a VR helmet, etc., which have a camera function. Figure 1 The electronic device 1000 in the illustrated embodiment is described by taking a mobile phone as an example.

[0124] Figure 2 yes Figure 1 The illustrated electronic device 1000 is a partial cross-sectional schematic diagram taken along AA in some embodiments.

[0125] like Figure 1 and Figure 2 As shown, in some embodiments, 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 is understood that Figure 1 The following figures and the related drawings only schematically illustrate some components of the electronic device 1000, and the actual shapes, sizes, positions and structures of these components are not limited to the following. Figure 1 In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may not include the screen 300 .

[0126] The device housing 200 may include a frame 201 and a back cover 202. The back cover 202 is fixed to the frame 201. Exemplarily, the back cover 202 may be fixedly connected to the frame 201 by means of gluing, snapping, etc. The back cover 202 may also be an integrally formed structure with the frame 201, that is, the back cover 202 and the frame 201 are an integral structure.

[0127] In some embodiments, the screen 300 may be located on a side of the frame 201 away from the back cover 202. In this case, the screen 300 and the back cover 202 may be located on both sides of the frame 201, respectively. 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 may be used to place components of the electronic device 1000, such as a battery, a receiver, or a microphone. The screen 300 may be a flat screen or a curved screen.

[0128] For example, the camera module 100 may be located inside the electronic device 1000. The back cover 202 has a light-transmitting portion 203. The shape of the light-transmitting portion 203 is not limited to the shape of the light-transmitting portion 203. Figure 1 The light outside the electronic device 1000 can enter the inside of the electronic device 1000 through the light-transmitting portion 203. The camera module 100 can collect the light entering the inside of the electronic device 1000. It can be understood that the specific structure of the light-transmitting portion 203 is not limited in this embodiment.

[0129] Figure 3 yes Figure 2 A partially exploded schematic diagram of some embodiments of the camera module 100 shown. It will be understood that, for ease of description hereinafter, the height direction of the camera module 100 is defined as the Z-axis direction. The width direction of the camera module 100 is the Y-axis direction. The length direction of the camera module 100 is the X-axis direction. In other embodiments, the coordinate system setting of the camera module 100 can be flexibly set according to specific actual needs. In this embodiment, the Z-axis direction is defined as the first direction. The X-axis direction is the second direction. The Y-axis direction is the third direction. In other embodiments, the first direction, the second direction, and the third direction can also be flexibly set according to specific actual needs, but it is necessary to ensure that the first direction, the second direction, and the third direction are different from each other.

[0130] like Figure 3 As shown, the camera module 100 may include a motor 1, a lens 2 and a photosensitive component 3.

[0131] Exemplarily, the lens 2 can be mounted on the motor 1. The lens 2 can be used to collect light. The optical axis direction of the lens 2 is parallel to the first direction Z of the camera module 100. The optical axis direction of the lens 2 is the same direction as the optical axis direction of the camera module 100.

[0132] For example, the motor 1 can realize autofocus (AF) by controlling the lens 2 to move along the first direction Z. The motor 1 can also adjust the amount of light entering the lens 2 so that the camera module 100 can maintain a constant shooting quality under various brightness conditions.

[0133] like Figure 3As shown, the photosensitive component 3 includes a module circuit board 31, an image sensor 32, a filter holder 33 and a filter 34. It is understandable that the image sensor 32 is also called a photosensitive chip or a photosensitive element. The image sensor 32 is used to convert the image information carried by the ambient light into an electrical signal. It is understandable that the photosensitive component 3 may include fewer or more structures. For example, the photosensitive component may include fewer structures. The photosensitive component 3 may not include a filter holder 33 and / or a filter 34. For another example, the photosensitive component 3 includes more structures. The photosensitive component 3 may also include electronic components. The electronic components may be capacitors, inductors or resistors, etc. The electronic components may be electrically connected to the image sensor 32.

[0134] like Figure 2 and Figure 3 As shown, in some embodiments, the image sensor 32 can be fixed to the module circuit board 31 and electrically connected to the module circuit board 31. At this time, the image sensor 32 and the module circuit board 31 can transmit signals to each other. The filter bracket 33 is fixedly connected to the module circuit board 31. The filter bracket 33 and the image sensor 32 can be located on the same side of the module circuit board 31. The filter bracket 33 is provided with a through hole 331. The filter 34 is fixedly connected to the filter bracket 33. The filter 34 can be located in the through hole 331. The filter 34 is also arranged opposite to the image sensor 32. The filter 34 can be used to filter infrared light or blue light in the light before entering the image sensor 32, so as to ensure that the image sensor 32 has better imaging quality.

[0135] like Figure 2 and Figure 3 As shown, in some embodiments, the motor 1 is fixed on the module circuit board 31 and is located on the same side of the module circuit board 31 as the image sensor 32. In the first direction Z, the image sensor 32, the filter 34 and the lens 2 are arranged in sequence. At this time, the image sensor 32 is located on the light exit side of the lens 2. The filter 34 is located between the lens 2 and the image sensor 32.

[0136] It can be understood that compared with the solution of fixing the motor 1 on the filter holder 33, this embodiment can avoid the stacking of the motor 1 and the filter holder 33 in the first direction Z by fixing the motor 1 on the module circuit board 31, that is, the motor 1 and the filter holder 33 can be staggered in the XY plane, thereby greatly reducing the height of the camera module 100.

[0137] Figure 4 yes Figure 3 A partially exploded schematic diagram of some embodiments of the motor 1 is shown.

[0138] like Figure 4As shown, exemplarily, the motor 1 includes a focus module 10 and a variable aperture module 20. The focus module 10 can achieve auto focus (AF) by controlling the lens 2 to move along the first direction Z. The variable aperture module 20 has an aperture hole 20a, and the size of the aperture hole 20a can be automatically adjusted. The aperture hole 20a can be located on the light incident side of the lens 2, that is, light can enter the lens 2 through the aperture hole 20a. In this way, the variable aperture module 20 can be used to adjust the amount of light entering, so that the camera module 100 can maintain a constant shooting quality under a variety of brightness conditions.

[0139] It can be understood that the focus module 10 drives the lens 2 to perform autofocus, and the variable aperture module 20 adjusts the amount of light entering the lens 2, and the focus module 10 and the variable aperture module 20 form an integrated motor 1. In this way, compared with the split motor in which the focus module 10 and the variable aperture module 20 are separately arranged, the motor 1 of this embodiment is smaller in size, which is conducive to realizing the miniaturization of the motor 1, thereby helping to save the internal space of the electronic device 1000.

[0140] like Figure 4 As shown, exemplarily, the focusing module 10 includes a base 11, a first carrier 12, a first support member 13, a focusing drive mechanism 14, a first circuit board assembly 15, a second circuit board assembly 16, and a housing 17. In other embodiments, the focusing module 10 may not include the first circuit board assembly 15 and / or the second circuit board assembly 16.

[0141] Exemplarily, the focus drive mechanism 14 includes a first focus coil 141, a second focus coil 142, a first focus magnetic member 143, and a second focus magnetic member 144. In other embodiments, the focus drive mechanism 14 may not include the second focus coil 142 and the second focus magnetic member 144.

[0142] Exemplarily, the first circuit board assembly 15 includes a first focus circuit board 151, a focus driving chip 152, a focus sensor 153 and a first reinforcement member 154. The focus sensor 153 may be a Hall sensor or a tunnel magneto-resistance (TMR) sensor. This application does not limit this in detail.

[0143] In other embodiments, the first circuit board assembly 15 may not include the focus driving chip 152 , and / or the focus sensor 153 , and / or the first reinforcement member 154 .

[0144] Exemplarily, the second circuit board assembly 16 includes a second focusing circuit board 161 and a second reinforcing member 162. In other embodiments, the second circuit board assembly 16 may not include the second reinforcing member 162.

[0145] like Figure 4 As shown, the variable aperture module 20 includes a second carrier 21, a second support member 22, an aperture driving mechanism 23, a plurality of blades 24, an upper cover 25, and a third circuit board assembly 26. Exemplarily, the second support member 22 adopts a ball structure. The number of the second support members 22 is four. In other embodiments, the structure and number of the second support members 22 are not specifically limited. In addition, in other embodiments, the variable aperture module 20 may not include the upper cover 25 and / or the third circuit board assembly 26.

[0146] Exemplarily, the aperture driving mechanism 23 includes a first aperture coil 231, a second aperture coil 232, a first aperture magnetic member 233, and a second aperture magnetic member 234. In other embodiments, the aperture driving mechanism 23 may not include the second aperture coil 232 and the second aperture magnetic member 234.

[0147] Figure 5 yes Figure 4 Schematic diagrams of the structure of some embodiments of the base 11 are shown.

[0148] like Figure 5 As shown, exemplarily, the base 11 includes a bottom plate 111, a first side plate 112 and a second side plate 113 arranged opposite to each other, and a third side plate 114 and a fourth side plate 115 arranged opposite to each other. The third side plate 114 and the fourth side plate 115 are connected between the first side plate 112 and the second side plate 113. The first side plate 112, the second side plate 113, the third side plate 114 and the fourth side plate 115 are connected to the periphery of the bottom plate 111. The first side plate 112, the second side plate 113, the third side plate 114, the fourth side plate 115 and the bottom plate 111 enclose an activity space 116 of the base.

[0149] It is understandable that the first side panel 112, the second side panel 113, the third side panel 114, the fourth side panel 115 and the bottom panel 111 are integrally formed structural members. In other embodiments, the first side panel 112, the second side panel 113, the third side panel 114, the fourth side panel 115 and the bottom panel 111 may also be connected to form a whole by other processes (such as welding, bonding or buckling, etc.).

[0150] like Figure 5 As shown, illustratively, the bottom plate 111 is provided with a first light-transmitting hole 117 . The first light-transmitting hole 117 is connected to the activity space 116 .

[0151] like Figure 5As shown, exemplarily, the base 11 is provided with a first fixing groove 118a and a second fixing groove 118b arranged at intervals. The first fixing groove 118a and the second fixing groove 118b are both oriented toward the activity space 116. In one embodiment, the first fixing groove 118a is located at the first side plate 112 of the base 11. The second fixing groove 118b is located at the second side plate 113 of the base 11.

[0152] like Figure 5 As shown, illustratively, the base 11 is further provided with a first groove 119. The extension direction of the first groove 119 may be parallel to the first direction Z. In one embodiment, the number of the first grooves 119 is two. The two first grooves 119 are arranged at intervals. In addition, one first groove 119 may be located on the third side plate 114, and the other first groove 119 may be located on the fourth side plate 115.

[0153] Figure 6 yes Figure 3 The partial structure diagram of some embodiments of the motor 1 shown Figure 1 .

[0154] like Figure 6 As shown, exemplarily, the first support member 13 includes a sliding shaft 131, that is, the first support member 13 adopts a sliding shaft structure. Exemplarily, the number of sliding shafts 131 is two. The two sliding shafts 131 are fixed in two first grooves 119 in a one-to-one correspondence. In other words, one sliding shaft 131 is fixed in one first groove 119. At this time, the sliding shaft 131 is fixed to the base 11. In other embodiments, the number of sliding shafts 131 is not limited.

[0155] Exemplarily, the peripheral side surface of the sliding shaft 131 may be fixed to the groove wall of the first groove 119 by adhesive or the like.

[0156] For example, a positioning block (not shown) may be convexly provided at the end of the sliding shaft 131. A positioning hole (not shown) may be provided in the first groove 119. The positioning block of the sliding shaft 131 is inserted into the positioning hole along the first direction Z. The positioning block and the positioning hole may be tightly matched. In this way, the connection between the sliding shaft 131 and the base 11 is more stable, that is, the sliding shaft 131 is not easily tilted relative to the base 11 to a large extent.

[0157] Figure 7 yes Figure 3 The diagrams show some partial structures of some embodiments of the first circuit board assembly 15 and the second circuit board assembly 16.

[0158] like Figure 7As shown, in some embodiments, the first focus coil 141 is fixed on the first focus circuit board 151 and electrically connected to the first focus circuit board 151. In addition, the focus driver chip 152 and the focus sensor 153 are both fixed on the first focus circuit board 151 and electrically connected to the first focus circuit board 151. It can be understood that the input and output ends of the first focus coil 141 can form a current loop with the first focus driver chip 152 through the first focus circuit board 151. At this time, the first focus driver chip 152 can control the current condition of the first focus coil 141 (for example, whether current is passed or the magnitude of the current when power is passed, etc.) through the first focus circuit board 151.

[0159] Exemplarily, the first focusing coil 141 can be arranged around the focusing driver chip 152 and the focusing sensor 153. In this way, the focusing driver chip 152 and the focusing sensor 153 can effectively utilize the inner space of the first focusing coil 141, thereby greatly improving the space utilization of the motor. In one embodiment, a plurality of first positioning blocks (not shown) may also be provided on the first focusing circuit board 151. A portion of the first positioning blocks may be located in the inner space of the first focusing coil 141, and a portion of the first positioning blocks may be located around the first focusing coil 141. The first positioning blocks can be used to improve the stability of the first focusing coil 141 to prevent the first focusing coil 141 from falling off the first focusing circuit board 151.

[0160] like Figure 7 As shown, in some embodiments, the first reinforcement member 154 is fixed to the side of the first focusing circuit board 151 facing away from the first focusing coil 141 to increase the structural strength of the first focusing circuit board 151 and reduce the risk of deformation of the first focusing circuit board 151.

[0161] like Figure 7 As shown, in some embodiments, the second focusing coil 142 is fixed on the second focusing circuit board 161 and electrically connected to the second focusing circuit board 161. In one embodiment, a plurality of second positioning blocks (not shown) may also be provided on the second focusing circuit board 161. A portion of the second positioning blocks may be located in the inner space of the second focusing coil 142, and a portion of the first positioning blocks may be located around the second focusing coil 142. The first positioning blocks may be used to improve the stability of the second focusing coil 142 to prevent the second focusing coil 142 from falling off the second focusing circuit board 161.

[0162] like Figure 7 As shown, in some embodiments, the second reinforcement member 162 is fixed to the side of the second focusing circuit board 161 facing away from the second focusing coil 142 to increase the structural strength of the second focusing circuit board 161 and reduce the risk of deformation of the second focusing circuit board 161.

[0163] Figure 8 yes Figure 3 The partial structure diagram of some embodiments of the motor 1 shown Figure 2 .

[0164] like Figure 8 As shown, exemplarily, the first circuit board assembly 15 is installed in the first fixing groove 118a to be fixed to the base 11. At this time, the first focusing coil 141 can be fixed to the base 11 by the first circuit board assembly 15. In one embodiment, the first reinforcement member 154 is fixed in the first fixing groove 118a by adhesive. At this time, the first focusing circuit board 151, the focus driving chip 152, the focus sensor 153 and the first focusing coil 141 can be fixed to the base 11 by the first reinforcement member 154. It can be understood that part of the first focusing circuit board 151 can also be fixed in the first fixing groove 118a by adhesive.

[0165] In other embodiments, when the first circuit board assembly 15 does not include the first reinforcing member 154, the first focusing circuit board 151 can be directly installed in the first fixing groove 118a to be fixed to the base 11. In other embodiments, if the base 11 is not provided with the first fixing groove 118a, the first circuit board assembly 15 can also be directly fixed to the first side plate 112 of the base 11.

[0166] It is understandable that by arranging the first circuit board assembly 15 and the first focusing coil 141 in the first fixing groove 118a. In this way, the first circuit board assembly 15, the first focusing coil 141 and the base 11 are arranged compactly, which is conducive to improving space utilization. In other embodiments, the size of the first fixing groove 118a can be reduced so that a portion of the first circuit board assembly 15 is located in the first fixing groove 118a and a portion is located outside the first fixing groove 118a, or the first focusing coil 141 is located outside the first fixing groove 118a.

[0167] like Figure 8 As shown, the first focusing coil 141 is located on a side of the first focusing circuit board 151 facing the activity space 116 of the base 11 .

[0168] Fig. 9 yes Figure 8 The schematic diagram of the structure of part of the motor 1 shown is from another angle.

[0169] like Fig. 9As shown, exemplarily, the second circuit board assembly 16 is installed in the second fixing groove 118b to be fixed to the base 11. At this time, the second focusing coil 142 can be fixed to the base 11 by the second circuit board assembly 16. In one embodiment, the second reinforcement member 162 is fixed in the second fixing groove 118b by adhesive. At this time, the second focusing circuit board 161 and the second focusing coil 142 can be fixed to the base 11 by the second reinforcement member 162. It can be understood that part of the second focusing circuit board 161 can also be fixed in the second fixing groove 118b by adhesive.

[0170] In other embodiments, when the second circuit board assembly 16 does not include the second reinforcement member 162, the second focusing circuit board 161 can be directly installed in the second fixing groove 118b to be fixed to the base 11. In other embodiments, if the base 11 is not provided with the second fixing groove 118b, the second circuit board assembly 16 can also be directly fixed on the second side plate 113 of the base 11.

[0171] It is understandable that by arranging the second circuit board assembly 16 and the second focusing coil 142 in the second fixing groove 118b. In this way, the second circuit board assembly 16, the second focusing coil 142 and the base 11 are arranged compactly, which is conducive to improving space utilization. In other embodiments, the size of the second fixing groove 118b can be reduced so that a part of the second circuit board assembly 16 is located in the second fixing groove 118b, and a part is located outside the second fixing groove 118b, or the second focusing coil 142 is located outside the second fixing groove 118b.

[0172] like Fig. 9 As shown, the second focusing coil 142 is located on a side of the second focusing circuit board 161 facing the activity space 116 of the base 11 .

[0173] Fig.10 yes Figure 3 Schematic diagrams of the structure of some embodiments of the first carrier 12 are shown. Fig.11 yes Fig.10 The structure schematic diagram of the first carrier 12 shown in another angle.

[0174] like Fig.10 and Fig.11 As shown, the first carrier 12 may be roughly annular. The middle of the first carrier 12 has an installation space 12a. The installation space 12a may pass through the top and bottom of the first carrier 12. The installation space 12a may form an opening at the top of the first carrier 12. The installation space 12a may be used to install the lens 2 (see Figure 3 ). For example, the central axis of the first carrier 12 is parallel to the lens 2 (see Figure 3 )’s optical axis.

[0175] Exemplarily, the first carrier 12 includes a first mounting portion 121 and a second mounting portion 120. Exemplarily, both the first mounting portion 121 and the second mounting portion 120 may be ring-shaped.

[0176] Exemplarily, the second mounting portion 120 includes a first sub-mounting portion 122 and a plurality of second sub-mounting portions 123. Exemplarily, the number of the second sub-mounting portions 123 may be four. In other embodiments, the number of the first mounting portion 121, the first sub-mounting portion 122, and the second sub-mounting portion 123 is not specifically limited. It is understood that in other embodiments, the second mounting portion 120 may also adopt other structures. For example, the second mounting portion 120 may also not include the second sub-mounting portion 123.

[0177] Exemplarily, the first mounting portion 121 includes an outer side surface 1211 and a top surface 1212 and a bottom surface 1213 disposed opposite to each other. The outer side surface 1211 is connected between the top surface 1212 and the bottom surface 1213. The inner side surface of the first mounting portion 121 encloses an inner space of the first mounting portion 121.

[0178] Exemplarily, the first sub-mounting portion 122 may be roughly annular. The first sub-mounting portion 122 is convexly disposed on the top surface 1212 of the first mounting portion 121. The first sub-mounting portion 122 and the first mounting portion 121 may be arranged along the first direction Z. Exemplarily, the side surface of the first sub-mounting portion 122 may be stepped, that is, the side surface of the first sub-mounting portion 122 has a stepped surface 1221. In other embodiments, the side surface of the first sub-mounting portion 122 may also be of any shape, which is not specifically limited in this application. Among them, the inner side surface of the first sub-mounting portion 122 encloses the inner space of the first sub-mounting portion 122. The inner space of the first sub-mounting portion 122 forms the inner space of the second mounting portion 120. The inner space of the first sub-mounting portion 122 is connected to the inner space of the first mounting portion 121, and constitutes the installation space 12a of the first carrier 12. In other words, a portion of the installation space 12a is located in the first mounting portion 121, and a portion is located in the first sub-mounting portion 122.

[0179] Exemplarily, the second sub-mounting portion 123 may be an arc-shaped block. The number of the second sub-mounting portion 123 may be multiple. The multiple second sub-mounting portions 123 are convexly arranged on the stepped surface 1221 of the first sub-mounting portion 122. The multiple second sub-mounting portions 123 may be arranged around the first sub-mounting portion 122 and spaced apart from a portion of the first sub-mounting portion 122. At this time, the first sub-mounting portion 122 is located on the inner side of the second sub-mounting portion 123.

[0180] It is understandable that the number of the second sub-mounting portions 123 is not limited to the four shown in the figure. For example, the number of the second sub-mounting portion 123 may also be one. One second sub-mounting portion 123 is annular and is disposed around the first sub-mounting portion 122 .

[0181] It is understandable that the second sub-mounting portion 123 is not limited to being protruded on the stepped surface 1221 of the first sub-mounting portion 122. In other embodiments, the second sub-mounting portion 123 may also be directly protruded on the top surface 1212 of the first mounting portion 121. This embodiment is not specifically limited.

[0182] like Fig.10 and Fig.11 As shown, exemplarily, the first mounting portion 121 is provided with a first mounting groove 1214 and a second mounting groove 1215 arranged at intervals. The openings of the first mounting groove 1214 and the second mounting groove 1215 are both located on the outer side 1211 of the first mounting portion 121. The first mounting groove 1214 and the second mounting groove 1215 are arranged in back to back.

[0183] Exemplarily, the first mounting portion 121 is provided with a third mounting groove 1216 and a fourth mounting groove 1217 which are spaced apart from each other. The openings of the third mounting groove 1216 and the fourth mounting groove 1217 are both located on the top surface 1212 of the first mounting portion 121 .

[0184] like Fig.10 and Fig.11 As shown, the first mounting portion 121 is provided with a second groove 1218. The second grooves 1218 are all opened on the outer side surface 1211, the top surface 1212 and the bottom surface 1213 of the first mounting portion 121. The extension direction of the second groove 1218 can be parallel to the first direction Z. In one embodiment, the number of the second grooves 1218 is two. The two second grooves 1218 are arranged at intervals.

[0185] like Fig.10 and Fig.11 As shown, the first sub-mounting portion 122 includes a plurality of first protrusions 1222. The first protrusions 1222 protrude in a direction away from the first mounting portion 121. For example, the shape of the first protrusions 1222 may be cylindrical. It is understood that the number of the first protrusions 1222 is not limited to Fig.10 and Fig.11 In other embodiments, the number of first protrusions 1222 is not specifically limited.

[0186] like Fig.10 and Fig.11As shown, exemplarily, the second sub-mounting portion 123 includes a body portion 1231 , a first convex portion 1232 and a second convex portion 1233 . The body portion 1231 is convexly disposed on the stepped surface 1221 of the first sub-mounting portion 122 .

[0187] Exemplarily, the first convex portion 1232 is convexly disposed on the inner side surface of the main body portion 1231. The inner side surface of the main body portion 1231 faces the first sub-mounting portion 122 and is spaced apart from the first sub-mounting portion 122. It is understandable that the first convex portion 1232 is further provided with a third groove 1237. The third groove 1237 forms an opening on the surface of the first convex portion 1232 away from the first mounting portion 121, and forms an opening on the surface of the first convex portion 1232 away from the main body portion 1231.

[0188] Exemplarily, the second protrusion 1233 is protruding from the top surface of the main body 1231. The top surface of the main body 1231 is the surface of the main body 1231 facing away from the first sub-mounting portion 122. It is understood that the number of the second protrusions 1233 is not limited to Fig.10 For example, the number of the second protrusions 1233 may be one, or more than two, etc. In addition, the shape of the second protrusion 1233 is not limited to Fig.10 and Fig.11 For example, the second convex portion 1233 may also be in the shape of a block.

[0189] Fig.12 yes Figure 3 The partial structure of the motor 1 in one embodiment is shown as follows: Figure 3 .

[0190] like Fig.12 As shown, in some embodiments, the first focusing magnetic member 143 can be installed in the first installation groove 1214 to be fixed to the first carrier 12. The second focusing magnetic member 144 can be installed in the second installation groove 1215 to be fixed to the first carrier 12. At this time, the second focusing magnetic member 144 can be located on a side of the first installation portion 121 away from the first focusing magnetic member 143.

[0191] In some embodiments, the focusing module 10 also includes a first focusing magnetic conductive member (not shown). The first focusing magnetic conductive member is made of magnetic conductive material. For example, silicon steel sheets and alloys formed by various iron products and rare earth elements. The first focusing magnetic conductive member can be fixed on the first carrier 12 and arranged opposite to the first focusing magnetic member 143. The first focusing magnetic conductive member can be used to enhance the magnetic field directivity of the first focusing magnetic member 143. In addition, the first focusing magnetic conductive member can generate an attractive force with the first focusing magnetic member 143, thereby preventing the first focusing magnetic member 143 from being separated from the first carrier 12. Exemplarily, the first focusing magnetic conductive member can form an integrally formed structural member with the first carrier 12 by means of insert-molding. At this time, the first focusing magnetic conductive member can be embedded in the first carrier 12. In other embodiments, the main part of the first focusing magnetic conductive member can be located between the first focusing magnetic member 143 and the bottom wall of the first mounting groove 1214. The first focusing magnetic conductive component can be fixed to the first carrier 12 by bonding or the like, and the first focusing magnetic component 143 can be fixed to the first focusing magnetic conductive component by bonding or the like.

[0192] Exemplarily, the focusing module 10 further includes a second focusing magnetic conductive member (not shown). The connection relationship between the second focusing magnetic conductive member and the first carrier 12 and the second focusing magnetic member 144 can refer to the connection relationship between the first focusing magnetic conductive member and the first carrier 12 and the first focusing magnetic member 143. The details are not repeated here.

[0193] Fig.13 yes Figure 3 The partial structure of the motor 1 in one embodiment is shown as follows: Figure 4 . Fig.14 yes Fig.13 The partial cross-sectional view of a partial motor 1 of an embodiment is shown at BB.

[0194] like Fig.13 and Fig.14 As shown, in some embodiments, the first carrier 12 is located inside the base 11. The installation space 12a of the first carrier 12 is connected to the first light-transmitting hole 117 of the base 11. In addition, the two second grooves 1218 of the first carrier 12 are arranged one-to-one with the two first grooves 119 of the base 11. The two sliding shafts 131 are arranged one-to-one in the two second grooves 1218. The groove wall of the second groove 1218 can slide relative to the sliding shaft 131.

[0195] It is understandable that the first carrier 12 is movably connected to the base 11 via the sliding shaft 131 , and the relative sliding direction of the two is parallel to the guiding direction of the sliding shaft 131 , that is, the first direction Z. The axial direction of the sliding shaft 131 is the guiding direction of the first support member 13 .

[0196] Fig.15 yes Fig.13 The partial cross-sectional view of a partial motor 1 at CC of an embodiment is shown.

[0197] like Fig.15 As shown, the first focus coil 141 and the second focus coil 142 are fixed to the base 11, and the first focus magnetic member 143 and the second focus magnetic member 144 are fixed to the first carrier 12. The first focus coil 141 is arranged facing the first focus magnetic member 143, and the second focus coil 142 faces the second focus magnetic member 144, which are used to drive the first carrier 12 to move along the first direction Z relative to the base 11. When the first carrier 12 moves along the first direction Z relative to the base 11, the first carrier 12 can drive the lens 2 installed thereon (see Figure 3 ) moves along the first direction Z. At this time, the motor 1 can realize the automatic focusing of the camera module 100. The first focusing coil 141 is arranged facing the first focusing magnetic member 143, which means that the winding plane of the first focusing coil 141 faces the first focusing magnetic member 143.

[0198] Exemplarily, the focus sensor 153 may be used to detect a position change of the first carrier 12 sliding in the first direction Z, so as to implement a closed-loop setting of the focus module 10 .

[0199] In this embodiment, during the movement of the first carrier 12 relative to the base 11, the movement direction of the first carrier 12 is perpendicular to the magnetic gap between the first focusing magnetic component 143 and the first focusing coil 141, and is also perpendicular to the magnetic gap between the second focusing magnetic component 144 and the second focusing coil 142. The above-mentioned magnetic gap is not affected by the movement of the first carrier 12, so the problem of rapid decrease in driving force due to the increase in magnetic gap can be avoided, thereby ensuring that the focus driving force of the motor is large and the driving force is relatively stable, which is conducive to the large stroke design of the motor's focus function.

[0200] The first focusing magnetic component 143 may have two polarity directions in opposite directions, and the polarity direction of the first focusing magnetic component 143 is arranged perpendicular to the winding plane of the first focusing coil 141. Among them, the coils in the two sections of the first focusing coil 141 may be arranged corresponding to the two polarity directions of the first focusing magnetic component 143 respectively, and the currents in the coils in the two sections flow in opposite directions. It can be understood that the polarity direction may be the direction from the North Pole (N) to the South Pole (S), or the direction from the South Pole (S) to the North Pole (N). At this time, the side of the first focusing magnetic component 143 facing the first focusing coil 141 includes the North Pole (N) and the South Pole (S), and the side of the first focusing magnetic component 143 facing away from the first focusing coil 141 includes the South Pole (S) and the North Pole (N) correspondingly.

[0201] Exemplarily, the first focusing magnetic component 143 may include one or more magnets, and the implementation structure of the first focusing magnetic component 143 may be multiple. For example, in some embodiments, the first focusing magnetic component 143 may adopt a dual magnet solution, for example, consisting of two magnets, the two magnets are arranged in the first direction Z, and the polarity directions are opposite. In other embodiments, the first focusing magnetic component 143 is a Halbach magnet array. In other embodiments, the first focusing magnetic component 143 may adopt a single magnet solution, for example, consisting of a magnet, the magnet includes two parts with opposite polarity directions. The magnet can be made using a bipolar magnetization process.

[0202] like Fig.15 As shown, the plane around which the wire of the first focusing coil 141 is wound (i.e., the winding plane) can be parallel to the first direction Z. At this time, the first focusing coil 141 is arranged vertically, so that the first focusing coil 141 can occupy a smaller area in the XY plane, which is beneficial to the miniaturization of the motor. The first focusing magnetic part 143 can include two opposite polarity directions, both of which are perpendicular to the first direction Z. At this time, the first focusing magnetic part 143 can be arranged vertically, thereby reducing the space occupied by the first focusing magnetic part 143 in the XY plane, which is convenient for the miniaturization design of the motor.

[0203] It is understandable that the arrangement of the second focus coil 142 and the second focus magnetic member 144 may refer to the arrangement of the first focus coil 141 and the first focus magnetic member 143. The details will not be repeated here.

[0204] like Fig.14 As shown, in some embodiments, the cooperation between the plurality of sliding shafts 131 and the first carrier 12 includes tight fit and loose fit to reduce the difficulty of assembly. Fig.14 As shown, the multiple second grooves 1218 of the first carrier 12 include at least one "V"-shaped groove and at least one "U"-shaped groove or "L"-shaped groove. When the "V"-shaped groove cooperates with the sliding shaft 131, the side groove wall of the second groove 1218 contacts the sliding shaft 131 to achieve a tight fit. When the "U"-shaped groove or "L"-shaped groove cooperates with the sliding shaft 131, the bottom groove wall of the second groove 1218 contacts the sliding shaft 131 to achieve a loose fit and can serve as a mating surface for absorbing tolerances. In some other embodiments, the tight fit and loose fit design between the multiple sliding shafts 131 and the first carrier 12 may have other implementation schemes, and the embodiments of the present application are not strictly limited to this.

[0205] like Fig.14 As shown, the slide shaft 131 can be made of magnetic conductive materials, such as silicon steel sheets and alloys formed by various iron products and rare earth elements.

[0206] Exemplarily, the focusing module 10 further includes a plurality of magnetic members 19. The magnetic members 19 may be magnets or other magnetic materials with magnetism. Exemplarily, the number of the magnetic members 19 may be equal to the number of the sliding shafts 131, that is, the number of the magnetic members 19 may be two. In other embodiments, the number of the magnetic members 19 is not specifically limited.

[0207] like Fig.14 As shown, the magnetic member 19 is fixed on the first carrier 12. The two magnetic members 19 are located one by one around the two sliding shafts 131. A magnetic attraction can be generated between the magnetic member 19 and the sliding shaft 131 to adsorb the first carrier 12 on the sliding shaft 131, so that the first carrier 12 has a tendency to approach the base 11, thereby ensuring that the first carrier 12 is not easy to fall off from the sliding shaft 131, and the first carrier 12 and the sliding shaft 131 can maintain contact, further achieving pre-tightening.

[0208] like Fig.13 As shown, in some embodiments, the first aperture magnetic member 233 may be installed in the third installation groove 1216 to be fixed to the first carrier 12 . The second aperture magnetic member 234 may be installed in the fourth installation groove 1217 to be fixed to the first carrier 12 .

[0209] Exemplarily, the variable aperture module 20 further includes a first aperture magnetic conductive member (not shown). The first aperture magnetic conductive member can be fixed on the first carrier 12 and arranged opposite to the first aperture magnetic member 233. The first aperture magnetic conductive member can be used to enhance the magnetic field directivity of the first aperture magnetic member 233. In addition, the first aperture magnetic conductive member can generate an attractive force with the first aperture magnetic member 233, thereby preventing the first aperture magnetic member 233 from being separated from the first carrier 12. Exemplarily, the first aperture magnetic conductive member can be formed into an integrally formed structural member with the first carrier 12 by means of insert-molding or the like. At this time, the first aperture magnetic conductive member can be embedded in the first carrier 12. In other embodiments, the main part of the first aperture magnetic conductive member can be located between the first aperture magnetic member 233 and the bottom wall of the third mounting groove 1216. Among them, the first aperture magnetic conductive member can be fixed to the first carrier 12 by means of bonding or the like, and the first aperture magnetic member 233 can be fixed to the first aperture magnetic conductive member by means of bonding or the like.

[0210] Exemplarily, the variable aperture module 20 further includes a second aperture magnetic conductive member (not shown). The connection relationship between the second aperture magnetic conductive member and the first carrier 12 and the second aperture magnetic member 234 can refer to the connection relationship between the first aperture magnetic conductive member and the first carrier 12 and the first aperture magnetic member 233. The details are not repeated here.

[0211] Fig.16 yes Figure 3Schematic diagrams of the structure of some embodiments of the second carrier 21 are shown.

[0212] like Fig.16 As shown, exemplarily, the second carrier 21 includes a main body 211, a first extension portion 212, and a second extension portion 213. The first extension portion 212 and the second extension portion 213 may be connected to the main body 211 at intervals and extend in a direction away from the center of the main body 211. Exemplarily, the second extension portion 213 is located on a side of the main body 211 away from the first extension portion 212. It is understood that in other embodiments, the structure of the second carrier 21 is not specifically limited, for example, the second carrier 21 may not include the second extension portion 213.

[0213] Exemplarily, the main body 211 may be roughly annular. The main body 211 includes a top surface 2111 and a bottom surface 2112 disposed opposite to each other, and an inner side surface 2113 and an outer side surface 2114 disposed opposite to each other. The top surface 2111 and the bottom surface 2112 of the main body 211 are connected between the inner side surface 2113 and the outer side surface 2114 of the main body 211. In other embodiments, the shape of the main body 211 is not specifically limited.

[0214] Exemplarily, the first extension portion 212 and the second extension portion 213 may be spaced apart and connected to the bottom surface 2112 of the main body 211. In other embodiments, the first extension portion 212 and the second extension portion 213 may also be spaced apart and connected to the outer side surface 2114 of the main body 211. This application does not limit this in detail.

[0215] like Fig.16 As shown, the top surface 2111 of the main body 211 is provided with a plurality of second protrusions 2115. The second protrusions 2115 protrude in a direction away from the bottom surface 2112 of the main body 211. Exemplarily, the second protrusions 2115 may be cylindrical. Exemplarily, the number of the second protrusions 2115 is six. In other embodiments, the number of the second protrusions 2115 is not specifically limited.

[0216] Exemplarily, the outer side surface 2114 of the main body 211 is convexly provided with a first protrusion 2116. The first protrusion 2116 protrudes in a direction away from the center of the main body 211. Exemplarily, the first protrusion 2116 can be an arc-shaped block. Exemplarily, the number of the first protrusions 2116 is four. In other embodiments, the number of the first protrusions 2116 is not specifically limited.

[0217] Exemplarily, the bottom surface 2112 of the main body 211 is convexly provided with a second protrusion 2117. The second protrusion 2117 protrudes in a direction away from the top surface 2111 of the main body 211. Exemplarily, the second protrusion 2117 can be an arc-shaped block. Exemplarily, the number of the second protrusions 2117 is four. In other embodiments, the number of the second protrusions 2117 is not specifically limited.

[0218] like Fig.16 As shown, exemplarily, the first extension portion 212 includes a first portion 2121, a second portion 2122 and a third portion 2123 connected in sequence. Among them, the first portion 2121 of the first extension portion 212 is connected to the main body 211. The third portion 2123 of the first extension portion 212 is located on a side of the second portion 2122 of the first extension portion 212 away from the main body 211. In the Z-axis direction, there is a height difference between the third portion 2123 of the first extension portion 212 and the first portion 2121 of the first extension portion 212. Exemplarily, the first extension portion 212 is stepped.

[0219] Exemplarily, the first extension portion 212 has a first receiving groove 2124. In one embodiment, the first receiving groove 2124 is located at the bottom of the third portion 2123 of the first extension portion 212.

[0220] like Fig.16 As shown, exemplarily, the second extension portion 213 includes a first portion 2131, a second portion 2132 and a third portion 2133 connected in sequence. Among them, the first portion 2131 of the second extension portion 213 is connected to the main body 211. The third portion 2133 of the second extension portion 213 is located on a side of the second portion 2132 of the second extension portion 213 away from the main body 211. In the Z-axis direction, there is a height difference between the third portion 2133 of the second extension portion 213 and the first portion 2131 of the second extension portion 213. Exemplarily, the second extension portion 213 is stepped.

[0221] like Fig.16 As shown, the second extension portion 213 has a second receiving groove 2134. In one embodiment, the second receiving groove 2134 is located at the bottom of the third portion 2133 of the second extension portion 213.

[0222] Exemplarily, the second extension portion 213 and the first extension portion 212 are centrally symmetrical with respect to the center of the main body portion 211 .

[0223] Fig.17 yes Figure 3 The partial structure of the motor 1 in one embodiment is shown as follows: Figure 5 .

[0224] like Fig.17As shown, the first aperture coil 231 and the second aperture coil 232 are fixed to the second carrier 21 at intervals.

[0225] Exemplarily, the first aperture coil 231 is fixed on the third portion 2123 of the first extension portion 212, and the first aperture coil 231 is located in the first receiving groove 2124 of the first extension portion 212. The second aperture coil 232 is fixed on the third portion 2133 of the second extension portion 213, and the second aperture coil 232 is located in the second receiving groove 2134 of the second extension portion 213.

[0226] Fig.18 yes Figure 3 The partial structure of the motor 1 in one embodiment is shown as follows: Figure 6 . Fig.19 yes Fig.18 The shown part is a partial cross-sectional view of one embodiment of a partial motor 1 at line DD.

[0227] like Fig.18 and Fig.19 As shown, the second carrier 21 is rotatably connected to the first carrier 12. It is understandable that this embodiment is described by taking the second carrier 21 as an example of being rotatably connected to the first carrier 12. In other embodiments, when the second carrier 21 adopts other structures, the second carrier 21 may also adopt other connection methods to be movably connected to the first carrier 12. This application does not specifically limit this.

[0228] Exemplarily, the second carrier 21 is located at the top of the first mounting portion 121 of the first carrier 12. Among them, the main body 211 of the second carrier 21 is located between the first sub-mounting portion 122 and the second sub-mounting portion 123 of the first carrier 12. The main body 211 of the second carrier 21 is arranged around the first sub-mounting portion 122. In addition, the main body 211 of the second carrier 21 is rotatably connected to the second sub-mounting portion 123. It can be understood that this embodiment is described by taking the main body 211 as an example of being rotatably connected to the second sub-mounting portion 123. In other embodiments, the second carrier 21 can also be rotatably connected to the first sub-mounting portion 122. Specifically, this application does not limit it. In other embodiments, the second carrier 21 can also be movably connected to the second sub-mounting portion 123 or the first sub-mounting portion 122. Specifically, this application does not limit it.

[0229] like Fig.19 As shown, the second support member 22 is disposed in the third groove 1237. Exemplarily, the number of the second support member 22 and the third groove 1237 are both four. At this time, the four second support members 22 can be disposed in the four third grooves 1237 in a one-to-one correspondence.

[0230] Exemplarily, the second support member 22 adopts a ball structure. In this case, the second support member 22 can roll in the third groove 1237. In other embodiments, the second support member 22 can also adopt a slider structure, such as an arc-shaped slider. In this case, the second support member 22 can be fixed in the third groove 1237. In other embodiments, the second support member 22 can also adopt other rolling member structures.

[0231] It is understandable that, since the second support member 22 adopts a ball structure, the second carrier 21 is rotatably connected to the first carrier 12 via the ball, so that the friction coefficient of the second carrier 21 relative to the first carrier 12 is small, which is conducive to greatly reducing the wear between the second carrier 21 and the first carrier 12.

[0232] like Fig.19 As shown, the first protrusion 2116 of the main body 211 of the second carrier 21 can be located between two adjacent second sub-mounting portions 123. When the second carrier 21 rotates relative to the first carrier 12, the two second sub-mounting portions 123 can function as stoppers, that is, prevent the second carrier 21 from deviating from a predetermined stroke.

[0233] In one embodiment, the second protrusion 2117 of the main body 211 of the second carrier 21 can abut against the first protrusion 1232 of the second sub-mounting portion 123 of the first carrier 12. In this way, in the Z-axis direction, the second sub-mounting portion 123 of the first carrier 12 can support the second carrier 21 to ensure that the second carrier 21 has better stability. In addition, the second protrusion 2117 can raise the height of the main body 211 relative to the first carrier 12, thereby facilitating the space for arranging the flexible circuit board 261.

[0234] like Fig.18 As shown, a portion of the first extension portion 212 passes through the space between the two second sub-mounting portions 123, and the third portion 2123 of the first extension portion 212 is disposed opposite to the top surface of the first mounting portion 121 of the first carrier 12. In one embodiment, the first portion 2121 of the first extension portion 212 may abut against the first sub-mounting portion 122 of the first carrier 12. In this way, in the Z-axis direction, the first sub-mounting portion 122 of the first carrier 12 may also support the second carrier 21 to ensure that the second carrier 21 has better stability.

[0235] like Fig.18As shown, a portion of the second extension portion 213 passes through the space between the two second sub-mounting portions 123, and the third portion 2133 of the second extension portion 213 is disposed opposite to the top surface of the first mounting portion 121 of the first carrier 12. In one embodiment, the first portion 2131 of the second extension portion 213 may abut against the first sub-mounting portion 122 of the first carrier 12. In this way, in the Z-axis direction, the first sub-mounting portion 122 of the first carrier 12 may also support the second carrier 21 to ensure that the second carrier 21 has better stability.

[0236] like Fig.18 As shown, the first aperture coil 231 and the second aperture coil 232 are fixed to the second carrier 21, and the first aperture magnetic member 233 and the second aperture magnetic member 234 are fixed to the first carrier 12. The first aperture coil 231 is arranged facing the first aperture magnetic member 233, and the second aperture coil 232 faces the second aperture magnetic member 234, so as to drive the second carrier 21 to rotate relative to the first carrier 12 in the XY plane. The first aperture coil 231 is arranged facing the first aperture magnetic member 233, which means that the winding plane of the first aperture coil 231 faces the first aperture magnetic member 233.

[0237] It is understandable that the first aperture magnetic member 233 may have two opposite polarity directions, and the polarity direction of the first aperture magnetic member 233 is arranged parallel to the winding plane of the first aperture coil 231. Among them, the coils of the two sections of the first aperture coil 231 may be arranged corresponding to the two polarity directions of the first aperture magnetic member 233, respectively, and the currents in the coils of the two sections flow in opposite directions. It is understandable that the polarity direction may be the direction from the north pole (N) to the south pole (S), or the direction from the south pole (S) to the north pole (N). At this time, the side of the first aperture magnetic member 233 facing the first aperture coil 231 includes the north pole (N) and the south pole (S), and the side of the first aperture magnetic member 233 facing away from the first aperture coil 231 includes the south pole (S) and the north pole (N) correspondingly.

[0238] Exemplarily, the first aperture magnetic component 233 may include one or more magnets, and the implementation structure of the first aperture magnetic component 233 may be multiple. For example, in some embodiments, the first aperture magnetic component 233 may adopt a dual magnet solution, for example, consisting of two magnets, the two magnets are arranged in the XY plane, and the polarity directions are opposite. In other embodiments, the first aperture magnetic component 233 is a Halbach magnet array. In other embodiments, the first aperture magnetic component 233 may adopt a single magnet solution, for example, consisting of a magnet, the magnet includes two parts with opposite polarity directions. The magnet can be made using a bipolar magnetization process.

[0239] like Fig.18As shown, the plane around which the wire of the first aperture coil 231 is wound (i.e., the winding plane) may be perpendicular to the first direction Z. At this time, the first aperture coil 231 is arranged flat. The first aperture magnetic member 233 may include two opposite polarity directions, both of which are parallel to the first direction Z. At this time, the first aperture magnetic member 233 may be arranged flat.

[0240] It is understandable that the configuration of the second aperture coil 232 and the second aperture magnetic member 234 may refer to the configuration of the first aperture coil 231 and the first aperture magnetic member 233. The details will not be repeated here.

[0241] Fig. 20 yes Figure 4 A schematic diagram of the structure of an embodiment of the plurality of blades 24 is shown. This embodiment takes one of the blades 24 as an example to specifically describe the structure of the blade 24. In one embodiment, the material of the blade 24 may be polyimide (PI). In other embodiments, the material of the blade 24 may also be a non-magnetic metal material. For example, an aluminum sheet. In this case, the hardness of the blade 24 is relatively high.

[0242] In one embodiment, a coating may be formed on the surface of the blade 24. For example, the coating is formed on the surface of the blade 24 by evaporation or sputtering. The coating can improve the smoothness of the blade 24, so that the friction between the blades 24 is small during the opening and closing process of the blades 24.

[0243] In one embodiment, the blade 24 includes an inner edge 241 and an outer edge 242. Exemplarily, the inner edge 241 and the outer edge 242 can be formed by an arc and a straight line cooperating with each other. In other embodiments, the shape of the blade 24 is not specifically limited.

[0244] In one embodiment, the blade 24 is provided with a rotation hole 243. Exemplarily, the rotation hole 243 may be a circular hole.

[0245] In one embodiment, the blade 24 is provided with a guide hole 244. Exemplarily, the guide hole 244 may be an arc-shaped hole. The guide hole 244 includes a first end wall 2441 and a second end wall 2442 that are arranged opposite to each other. The first end wall 2441 is arranged relative to the second end wall 2442 and close to the rotating hole.

[0246] Fig.21 yes Figure 3 The partial structure of the motor 1 in one embodiment is shown as follows: Figure 7 In this embodiment, one of the blades 24 is taken as an example to specifically describe the connection relationship between the blade 24 and the first carrier 12 and the second carrier 21 .

[0247] See also Fig.21, and combined with Fig.19 As shown, the plurality of blades 24 are located at the top of the first carrier 12 and the second carrier 21. Exemplarily, the plurality of blades 24 are located on a side of the first sub-mounting portion 122 away from the first mounting portion 121. It is understandable that when the first carrier 12 and the second carrier 21 adopt other structures, the blades 24 may also be located at other positions of the first carrier 12 and the second carrier 21, which is not specifically limited in the present application.

[0248] Exemplarily, the blade 24 is slidably connected to the first carrier 12. Exemplarily, the blade 24 is slidably connected to the first sub-mounting portion 122 of the first carrier 12. Exemplarily, the plurality of first protrusions 1222 pass through the guide holes 244 of the plurality of blades 24 in a one-to-one correspondence, that is, one first protrusion 1222 passes through the guide hole 244 of one blade 24. It can be understood that the first protrusion 1222 can slide relative to the hole wall of the guide hole 244. In this way, through the cooperation between the guide hole 244 and the first protrusion 1222, the blade 24 can be slidably connected to the first carrier 12.

[0249] In other embodiments, the positions of the first protrusion 1222 and the guide hole 244 can be swapped. In other words, the first protrusion 1222 can be disposed on the blade 24 , and the guide hole 244 can be disposed on the first carrier 12 .

[0250] In addition, the blade 24 is rotatably connected to the second carrier 21. Exemplarily, the blade 24 is rotatably connected to the main body 211 of the second carrier 21. Exemplarily, the plurality of second protrusions 2115 of the second carrier 21 pass through the plurality of rotating holes 243 of the blade 24 in a one-to-one correspondence, that is, one second protrusion 2115 of the second carrier 21 passes through one rotating hole 243 of the blade 24. It can be understood that the hole wall of the rotating hole 243 can rotate relative to the second protrusion 2115. In this way, through the cooperation between the rotating hole 243 and the second protrusion 2115, the blade 24 can rotate the second carrier 21 with the second protrusion 2115 as the rotating axis.

[0251] In other embodiments, the positions of the second protrusion 2115 and the rotating hole 243 can be swapped. The second protrusion 2115 is disposed on the blade 24 . The rotating hole 243 is disposed on the second carrier 21 .

[0252] It is understandable that this embodiment is described by taking the example that the blade 24 is rotatably connected to the second carrier 21 and the blade 24 is slidably connected to the first carrier 12. In other embodiments, the connection method of the blade 24 and the first carrier 12 and the second carrier 21 is not specifically limited.

[0253] like Fig.21As shown, the plurality of blades 24 are distributed in a ring shape, and the blades 24 together surround the aperture hole 20a. Exemplarily, the inner edges 241 of the plurality of blades 24 together surround the aperture hole 20a. The aperture hole 20a is connected to the installation space 12a. Exemplarily, the aperture hole 20a is connected to the inner space of the first sub-mounting portion 122. It can be understood that, since each blade 24 is slidably connected to the first carrier 12, and each blade 24 is rotatably connected to the second carrier 21, when the second carrier 21 rotates relative to the first carrier 12, the second carrier 21 can drive the plurality of blades 24 to move, and at this time, the plurality of blades 24 are unfolded or closed, and the aperture of the aperture hole 20a of the plurality of blades 24 can be enlarged or reduced, and the shape of the aperture hole 20a of the plurality of blades 24 can change. Of course, in other embodiments, the shape of the inner edge 241 of each blade 24 can be changed so that when the multiple blades 24 are expanded or closed, the aperture 20a of the multiple blades 24 can become larger or smaller, but the shape of the aperture 20a of the multiple blades 24 will not change.

[0254] It is understandable that a gasket (not shown) may be provided between the blade 24 and the second carrier 21. In this way, when the blade 24 is unfolded or closed, the gasket may prevent the second carrier 21 from scratching the blade 24.

[0255] In one embodiment, the central axis of the aperture hole 20a of the plurality of blades 24 coincides with the central axis of the first carrier 12 and the central axis of the second carrier 21. For example, the central axis of the aperture hole 20a of the plurality of blades 24 refers to a virtual axis that passes through the center of the aperture hole 20a of the plurality of blades 24 and is perpendicular to the plane where the plurality of blades 24 are located. In other embodiments, the central axis of the aperture hole 20a of the plurality of blades 24 may not coincide with the central axis of the first carrier 12.

[0256] In one embodiment, when the variable aperture module 20 is in the initial state, the first protrusion 1222 of the first carrier 12 contacts the first end wall 2441 of the guide hole 244, and the aperture hole 20a is at its smallest. When the variable aperture module 20 is in the final state, the first protrusion 1222 of the first carrier 12 contacts the second end wall 2442 of the guide hole 244, and the aperture hole 20a is at its largest. When the variable aperture module 20 is in the middle state, the first protrusion 1222 of the first carrier 12 is located between the first end wall 2441 and the second end wall 2442 of the guide hole 244.

[0257] In one embodiment, when the variable aperture module 20 is in the initial state, that is, when the aperture hole 20a has the smallest aperture, the first protrusion 2116 abuts against the first second sub-mounting portion 123 (that is, the second sub-mounting portion 123 on the left side of the first protrusion 2116). When the variable aperture module 20 is in the terminal state, when the aperture hole 20a has the largest aperture, the first protrusion 2116 abuts against the second second sub-mounting portion 123 (that is, the second sub-mounting portion 123 on the right side of the first protrusion 2116). Therefore, when the second carrier 21 rotates relative to the first carrier 12, the two second sub-mounting portions 123 can stop the second carrier 21, that is, prevent the second carrier 21 from deviating from the predetermined stroke.

[0258] In one embodiment, the variable aperture module 20 further includes an aperture sensor (not shown). The aperture sensor 263 can be fixed on the first extension portion 212 of the second carrier 21. The first aperture coil 231 can be arranged around the aperture sensor. In this way, the aperture sensor can effectively utilize the inner space of the first aperture coil 231, thereby greatly improving the space utilization of the motor 1.

[0259] It is understandable that the aperture sensor 263 can be used to detect the position change of the second carrier 21 during the rotation process in the XY plane. The aperture sensor can be a Hall sensor or a tunnel magneto-resistance (TMR) sensor. The present application does not make any specific limitations.

[0260] Fig.22A yes Figure 3 The partial structure of the motor 1 in one embodiment is shown as follows: Figure 8 .

[0261] like Fig.22A As shown, the upper cover 25 can be an annular structure. The upper cover 25 surrounds the second light-transmitting hole 251. The upper cover 25 can be an integral structural member or a spliced ​​structural member. For example, multiple parts are formed into an integral structural member by splicing (such as mortise and tenon technology) or fixing (such as welding, bonding and other processes). This embodiment is described by taking the upper cover 25 as an integral structural member as an example.

[0262] It is understandable that the material of the upper cover 25 can be metal material, such as aluminum sheet or steel sheet. The material of the upper cover 25 can also be plastic, such as polyimide (PI). The material of the upper cover 25 can also be a mixed structure of plastic and metal materials. For example, an insert molding process is used to place a metal material such as an aluminum sheet in a mold and injection mold it into an integral part.

[0263] In one embodiment, the upper cover 25 may be provided with a fixing hole 252. The number of the fixing hole 252 may be one or more. When the number of the fixing hole 252 is more than one, the fixing hole 252 is arranged around the second light-transmitting hole 251 of the upper cover 25.

[0264] See also Fig.22A , and combined with Fig.21 As shown, the upper cover 25 is fixed on the first carrier 12. The upper cover 25 is located on the side of the plurality of blades 24 away from the second carrier 21. In this way, in the Z-axis direction, the upper cover 25 can limit the plurality of blades 24, thereby preventing the plurality of blades 24 from falling out. In addition, the second light-transmitting hole 251 of the upper cover 25 is arranged opposite to the aperture hole 20a of the plurality of blades 24. In this way, the ambient light can be transmitted to the aperture hole 20a of the plurality of blades 24 through the second light-transmitting hole 251 of the upper cover 25.

[0265] Exemplarily, the upper cover 25 is fixed on the second sub-mounting portion 123 of the first carrier 12, and the second protrusion 1233 of the second sub-mounting portion 123 passes through the fixing hole 252 of the upper cover 25. When the number of the second protrusion 1233 of the second sub-mounting portion 123 and the fixing hole 252 is multiple, the multiple second protrusions 1233 pass through the multiple fixing holes 252 in a one-to-one correspondence, that is, one second protrusion 1233 passes through one fixing hole 252. In this way, the connection between the upper cover 25 and the first carrier 12 is more secure. At this time, the upper cover 25 is not easy to fall off from the first carrier 12.

[0266] like Fig.22A As shown, in one embodiment, the housing 17 is fixed to the base 11. Exemplarily, at least part of the housing 17 is fixed to the first side plate 112, the second side plate 113, the third side plate 114 and the fourth side plate 115 of the base 11. The housing 17 and the base 11 can enclose a space for accommodating the relevant components of the motor 1. In addition, the first sub-mounting portion 122 and the second sub-mounting portion 123 of the first carrier 12 and the components mounted on the first sub-mounting portion 122 and the second sub-mounting portion 123 (for example, the second carrier 21, the blades 24 and the upper cover 25, etc.) all pass through the housing 17 and are exposed relative to the housing 17.

[0267] Fig. 22B It is a partial cross-sectional schematic diagram of some embodiments of the camera module 100 provided in the embodiments of the present application.

[0268] like Fig. 22B As shown, the lens 2 is installed in the installation space 12a of the first carrier 12, wherein the head of the lens 2 is directly opposite to the aperture hole 20a, and the tail of the lens 2 is directly opposite to the first light-transmitting hole 117 of the bottom plate 111 of the base 11.

[0269] Exemplarily, the head of the lens 2 is installed in the inner space of the first sub-mounting portion 122 , and the tail of the lens 2 is installed in the inner space of the first mounting portion 121 .

[0270] It can be understood that the first focus coil 141 is arranged facing the first focus magnetic member 143, and the second focus coil 142 is arranged facing the second focus magnetic member 144, and is used to drive the first carrier 12 to move relative to the base 11 along the first direction Z. When the first carrier 12 moves relative to the base 11 along the first direction Z, the first carrier 12 can drive the lens 2 mounted thereon to move along the first direction Z. At this time, the motor 1 can realize automatic focusing of the camera module 100.

[0271] In addition, the size of the aperture hole 20a can be automatically adjusted. The aperture hole 20a can be located on the light-entering side of the lens 2, that is, light can enter the lens 2 through the aperture hole 20a. In this way, the variable aperture module 20 can be used to adjust the amount of incoming light, so that the camera module 100 can maintain a constant shooting quality under various brightness conditions.

[0272] It is understandable that the above text specifically introduces a motor 1 structure that integrates the focus module 10 and the variable aperture module 20 in combination with the relevant drawings. Specifically, the first carrier 12 of the present application can be used to install the lens 2 to drive the lens 2 to move along the first direction Z under the driving force of the focus drive mechanism 14, thereby realizing automatic focusing; it can also be used to connect the blades 24 to cooperate with the second carrier 21, so as to drive the multiple blades 24 to open and close under the driving force of the aperture drive mechanism 23, and the aperture 20a of the multiple blades 24 can be enlarged or reduced. In this way, the variable aperture module 20 can be used to adjust the amount of light entering, so that the camera module 100 can maintain a constant shooting quality under various brightness conditions.

[0273] In one embodiment, the motor 1 is formed by assembling two independent structural parts, namely a variable aperture and a focus motor. During the preparation process of the motor, the variable aperture and the focus motor need to be prepared separately first, and then the variable aperture and the focus motor are sent to the module factory for assembly. At this time, the variable aperture needs to be positioned and calibrated, and finally it is welded to the focus motor. This assembly process is complicated and costly. In the present application, the focus module 10 and the variable aperture module 20 are integrated into one to form a motor 1 with an integrated structure. On the one hand, the motor 1 is smaller in size, which is conducive to the miniaturization of the motor 1, thereby saving the internal space of the electronic device 100. On the other hand, the motor 1 of the present application no longer needs to prepare the variable aperture and the focus motor separately, and then send them to the module factory for calibration and assembly. The motor 1 of the present application can simplify the assembly process and reduce cost investment.

[0274] It is understandable that the variable aperture module 20 of the motor 1 of the present application adopts a moving coil setting, and the drive of the variable aperture module 20 in the XY plane is controlled solely by the aperture drive mechanism 23 (the first aperture coil 231, the first aperture magnetic part 233, the second aperture coil 232, and the second aperture magnetic part 234). Among them, the second carrier 21 of the motor 1 rotates in the XY plane relative to the first carrier 12, that is, during the process of adjusting the size of the aperture hole 20a, the relative position of the first carrier 12 and the base 11 is not affected, and the magnetic gap of the focus drive mechanism 14 is not easy to change. Similarly, the focus module 10 of the motor 1 of the present application adopts a moving magnet setting, and the drive of the focus module 10 in the first direction Z is controlled solely by the focus drive mechanism 14 (the first focus coil 141, the first focus magnetic part 143, the second light focus coil, and the second focus magnetic part 144). The first carrier 12 of the motor 1 moves relative to the base 11 along the first direction Z, that is, during the autofocus process, the relative position of the first carrier 12 and the second carrier 21 is not affected, and the magnetic gap of the aperture drive mechanism 23 of the variable aperture module 20 is not easily changed. Therefore, the focus drive mechanism 14 and the aperture drive mechanism 23 of the motor 1 are decoupled and do not interfere with each other during the movement, which is conducive to ensuring the driving accuracy of the motor 1.

[0275] It can be understood that, in this embodiment, the first focusing magnetic component 143, the second focusing magnetic component 144, the first aperture magnetic component 233 and the second aperture magnetic component 234 are all fixed to the first carrier 12, so that during the focusing process of the motor 1 and the process of adjusting the size of the aperture hole 20a, the relative positions of the first focusing magnetic component 143, the second focusing magnetic component 144 of the focusing module 10 and the first aperture magnetic component 233, the second aperture magnetic component 234 of the variable aperture module 20 will not change. In this way, there is no coupling effect between the first focusing magnetic component 143, the second focusing magnetic component 144 of the focusing module 10 and the first aperture magnetic component 233, the second aperture magnetic component 234 of the variable aperture module 20, that is, the first focusing magnetic component 143, the second focusing magnetic component 144 of the focusing module 10 will not generate magnetic interference with the first aperture magnetic component 233, the second aperture magnetic component 234 of the variable aperture module 20. The first aperture magnetic component 233 and the second aperture magnetic component 234 of the variable aperture module 20 will not generate magnetic interference to the first focusing magnetic component 143 and the second focusing magnetic component 144 of the focusing module 10 .

[0276] The above specifically introduces a structure of a motor 1 in conjunction with the relevant drawings. The following specifically introduces some implementations of the variable aperture module 20 of the motor 1 in conjunction with the relevant drawings.

[0277] Fig.23 yes Figure 4 An exploded schematic diagram of an embodiment of the third circuit board assembly 26 is shown. Fig.24 yes Fig.23 The diagram shows an assembly diagram of an embodiment of the third circuit board assembly 26 and the first aperture coil 231.

[0278] like Fig.23 and Fig.24 As shown, in one embodiment, the third circuit board assembly 26 includes a flexible circuit board 261 and an aperture driving chip 262. The flexible circuit board 261 may be an integral circuit board structure or may be formed by connecting a plurality of sub-circuit boards to each other. The following description is made by taking the flexible circuit board 261 as an example in which two sub-circuit boards are connected to each other. Exemplarily, the flexible circuit board 261 includes a first sub-circuit board 261a and a second sub-circuit board 261b. The first end of the second sub-circuit board 261b is connected to the second end of the first sub-circuit board 261a. It can be understood that the first end of the first sub-circuit board 261a can be formed as the first end 2611 of the flexible circuit board 261. The second end of the second sub-circuit board 261b can be formed as the second end 2613 of the flexible circuit board 261. The middle part, the second end of the first sub-circuit board 261a and the first end and the middle part of the second sub-circuit board 261b can form the middle part 2612 of the flexible circuit board 261.

[0279] like Fig.24 As shown, the first aperture coil 231 and the aperture driving chip 262 are both fixed on the first end 2611 of the flexible circuit board 261, and are both electrically connected to the flexible circuit board 261. The input end and the output end of the first aperture coil 231 form a current loop through the flexible circuit board 261 and the aperture driving chip 262. The aperture driving chip 262 can control the current of the first aperture coil 231 (for example, whether the current is passed or the magnitude of the current when the current is passed) through the flexible circuit board 261. In one embodiment, the first aperture coil 231 can be arranged around the aperture driving chip 262. In this way, the aperture driving chip 262 can effectively utilize the inner space of the first aperture coil 231, thereby greatly improving the space utilization rate of the motor 1. In other embodiments, the first aperture coil 231 and the aperture driving chip 262 can also be fixed at other positions of the flexible circuit board 261. Specifically, this application is not limited.

[0280] It is understandable that in other embodiments, the function of the aperture sensor may also be integrated into the aperture driving chip 262. In this case, the aperture driving chip 262 may be used to detect the position change of the second carrier 21 during the rotation process of the XY plane.

[0281] Fig.25 yes Figure 3 The partial structure of the motor 1 in one embodiment is shown as follows: Figure 9 . Fig.26yes Figure 3 The partial structure of the motor 1 in one embodiment is shown as follows: Figure 10 .

[0282] like Fig.25 and Fig.26 As shown, the first end portion 2611 of the flexible circuit board 261 is fixed on the first extension portion 212 of the second carrier 21 and is located in the first receiving groove 2124. At this time, the first aperture coil 231 and the aperture driving chip 262 (see Fig.24 ) is fixed on the second carrier 21 through the flexible circuit board 261.

[0283] In addition, the middle portion 2612 of the flexible circuit board 261 is located between the first sub-mounting portion 122 and the second sub-mounting portion 123 of the first carrier 12. The middle portion 2612 of the flexible circuit board 261 is also arranged around the first sub-mounting portion 122 of the first carrier 12. Exemplarily, the middle portion 2612 of the flexible circuit board 261 is arranged approximately around three quarters of the first sub-mounting portion 122 of the first carrier 12.

[0284] In addition, the second end portion 2613 of the flexible circuit board 261 is fixed on the first carrier 12. Exemplarily, the second end portion 2613 of the flexible circuit board 261 is fixed on the second sub-mounting portion 123 of the first carrier 12.

[0285] It is understandable that the four traces in the flexible circuit board 261 are electrically connected to the four first conductive members (not shown) in the first carrier 12 in a one-to-one correspondence. The four first conductive members can be embedded in the first carrier 12. One trace in the flexible circuit board 261 can be used as an aperture driver chip 262 (see Fig.24 ) is a transmission channel for the negative electrode of the power supply. A trace in the flexible circuit board 261 can be used as an aperture drive chip 262 (see Fig.24 ) is a transmission channel for the positive electrode of the power supply. A trace in the flexible circuit board 261 can be used as an aperture drive chip 262 (see Fig.24 ) is a transmission channel for the SDA signal of the flexible circuit board 261. A trace in the flexible circuit board 261 can be used as an aperture driver chip 262 (see Fig.24 )'s SCL signal transmission channel.

[0286] Exemplarily, the four first conductive members (not shown) in the first carrier 12 can be electrically connected to the four second conductive members (not shown) in the base 11 through four connecting springs (not shown). It can be understood that the four second conductive members can be embedded in the base 11. In this way, the aperture driving chip 262 can be electrically connected to the four second conductive members in the base 11 through the flexible circuit board 261, the four first conductive members in the first carrier 12, and the four connecting springs.

[0287] The above describes an implementation method of how to electrically connect the first aperture coil 231 to the second conductive member of the base 11. Fig.22A ) can refer to the electrical connection method of the first aperture coil 231. The details will not be repeated here. In other embodiments, the second aperture coil 232 can also be electrically connected to the flexible circuit board 261 through the conductive member in the second carrier 21, and a current loop is formed through the flexible circuit board 261 and the aperture driving chip 262. The aperture driving chip 262 can control the current condition of the second aperture coil 232 (for example, whether current is passed or the magnitude of the current when power is passed) through the flexible circuit board 261. It can be understood that the first aperture coil 231 and the second aperture coil 232 can be connected in parallel with the flexible circuit board 261 through the conductive member in the second carrier 21, or in series.

[0288] The above text specifically introduces several implementations of the motor in conjunction with the relevant drawings. The following text will further specifically introduce the structures of several motors in conjunction with the relevant drawings.

[0289] The second implementation mode, the same technical contents as the above implementation modes are not repeated here: Fig. 27 FIG. 1 is a partial cross-sectional view of another motor 1 provided in an embodiment of the present application. Fig. 27 As shown, the first support member 13 adopts a ball structure, that is, the first support member 13 includes a ball 132. The first groove 119 of the base 11 and the second groove 1218 of the first carrier 12 form a ball groove. The ball 132 is arranged in the ball groove. The ball 132 can roll in the ball groove.

[0290] It is understandable that the number of balls 132 in the ball groove may not be limited to Fig. 27 For example, the number of the balls 132 may be one, two or more than three. When the number of the balls 132 is multiple, the arrangement direction of the multiple balls 132 is the guiding direction of the first support member 13.

[0291] like Fig. 27 As shown, the first carrier 12 is movably connected to the base 11 through the ball bearing 132. It can be understood that, compared with the first support member 13 adopting a sliding shaft structure, on the one hand, the contact area between the first carrier 12 and the ball bearing 132 is smaller, and the friction between the first carrier 12 and the ball bearing 132 is smaller, which is beneficial to reducing the loss of the motor 1; on the other hand, the cost of the ball bearing 132 is lower, which is beneficial to reducing the cost investment of the motor 1.

[0292] The third implementation mode, the same technical contents as the above implementation modes are not repeated here: Fig.28It is a schematic structural diagram of another first support member 13 provided in an embodiment of the present application. Fig.29 This is a partial structural diagram of another motor 1 provided in an embodiment of the present application. Figure 1 .

[0293] like Fig.28 and Fig.29 As shown, the first support member 13 adopts a leaf spring structure, that is, the first support member 13 includes a leaf spring 133. The number of the leaf spring 133 can be one or more. The number of the leaf spring 133 in this embodiment is described by taking one as an example.

[0294] Exemplarily, the reed 133 includes a first fixing portion 1331, a connecting portion 1332, and a second fixing portion 1333. The connecting portion 1332 of the reed 133 is connected between the first fixing portion 1331 of the reed 133 and the second fixing portion 1333 of the reed 133. Exemplarily, the first fixing portion 1331 and the second fixing portion 1333 of the reed 133 are both annular. The connecting portion 1332 of the reed 133 is generally bent. The number of the connecting portions 1332 of the reed 133 is not limited to Fig.28 and Fig.29 Four are shown, but the specific number is not limited.

[0295] like Fig.28 and Fig.29 As shown, the reed 133 is connected between the base 11 and the first carrier 12. Exemplarily, the first fixing portion 1331 of the reed 133 is fixed on the base 11. The second fixing portion 1333 of the reed 133 is fixed on the first carrier 12. In this way, the first carrier 12 can be movably connected to the base 11 through the reed 133.

[0296] In one embodiment, the first fixing portion 1331 of the reed 133 is fixed to the surfaces of the first side plate 112, the second side plate 113, the third side plate 114 and the fourth side plate 115 of the base 11 away from the bottom plate 111. The second fixing portion 1333 of the reed 133 is fixed to the first mounting portion 121 of the first carrier 12.

[0297] It can be understood that when the focus driving mechanism 14 (including the first focus coil 141, the second focus coil 142, the first focus magnetic member 143 and the second focus magnetic member 144) applies a driving force to the first carrier 12, the first carrier 12 overcomes the elastic force of the reed 133 and moves relative to the base 11 along the first direction Z. When the focus driving mechanism 14 stops applying the driving force to the first carrier 12, the reed 133 can provide a restoring force to the first carrier 12 through its own elastic force, so that the first carrier 12 returns to its original position.

[0298] It can be understood that compared with the first support member 13 adopting the sliding shaft 131 structure, the first support member 13 of this embodiment adopts the reed 133 structure. On the one hand, the reed 133 can provide a reset force to the first carrier 12, thereby reducing the power consumption of the first carrier 12 returning to its original position; on the other hand, the cost of the reed 133 is relatively low, which is conducive to reducing the cost investment of the motor 1.

[0299] The fourth implementation mode, the same technical contents as the above implementation modes are not repeated here: Fig.30 yes Figure 4 A schematic structural diagram of another embodiment of the third circuit board assembly 26 and the first aperture coil 231 is shown. Fig.31 This is a partial structural diagram of another motor 1 provided in an embodiment of the present application. Figure 2 .

[0300] like Fig.30 and Fig.31 As shown, in one embodiment, the third circuit board assembly 26 includes a flexible circuit board 261 and an aperture driving chip 262. The first aperture coil 231 and the aperture driving chip 262 are both fixed on the flexible circuit board 261 and are both electrically connected to the flexible circuit board 261. The input end and the output end of the first aperture coil 231 form a current loop through the flexible circuit board 261 and the aperture driving chip 262. The aperture driving chip 262 can control the current of the first aperture coil 231 (for example, whether the current is passed or the magnitude of the current when the current is passed) through the flexible circuit board 261. In one embodiment, the first aperture coil 231 can be arranged around the aperture driving chip 262. In this way, the aperture driving chip 262 can effectively utilize the inner space of the first aperture coil 231, thereby greatly improving the space utilization rate of the motor 1. In other embodiments, the first aperture coil 231 and the aperture driving chip 262 can also be fixed at other positions of the flexible circuit board 261. Specifically, this application is not limited.

[0301] like Fig.30 and Fig.31 As shown, the flexible circuit board 261 is fixed on the first extension portion 212 of the second carrier 21 and is located in the first receiving groove 2124. At this time, the first aperture coil 231 and the aperture driving chip 262 are fixed on the second carrier 21 through the flexible circuit board 261.

[0302] It can be understood that the multiple traces (not shown) in the flexible circuit board 261 are electrically connected to the multiple first electrical connectors (not shown) in the second carrier 21 in a one-to-one correspondence. The multiple first electrical connectors can be embedded in the second carrier 21. The multiple traces in the flexible circuit board 261 can be used as transmission channels for the negative power supply of the aperture driver chip 262, the positive power supply, the SDA signal, and the SCL signal.

[0303] like Fig.31 As shown, the variable aperture module 20 further includes a plurality of elastic members 263. The elastic member 263 includes a first end 2631, a middle portion 2632, and a second end 2633 connected in sequence. Exemplarily, the first end 2631 and the second end 2633 of the elastic member 263 are both block-shaped. The middle portion 2632 of the elastic member 263 is bent.

[0304] Among them, the first end 2631 of the elastic member 263 is fixed on the second carrier 21, and the second end 2633 of the elastic member 263 is fixed on the first carrier 12. It is understandable that the fixing method between the elastic member 263 and the first carrier and the second carrier can be snap-fit, welding or bonding. Specifically, this application does not limit it. Exemplarily, the first end 2631 of the elastic member 263 can be fixed on the first extension portion 212 of the second carrier 21. The second end 2633 of the elastic member 263 can be fixed on the second sub-mounting portion 123 of the first carrier 12.

[0305] like Fig.31 As shown, the first ends 2631 of the plurality of elastic members 263 are electrically connected to the plurality of first electrical connectors (not shown) in the second carrier 21 in a one-to-one correspondence. The first ends 2631 of the plurality of elastic members 263 are electrically connected to the plurality of second electrical connectors (not shown) in the first carrier 12 in a one-to-one correspondence. The electrical connection method of the plurality of second electrical connectors in the first carrier 12 and the plurality of second conductive members of the base can refer to the above embodiments ( Figure 23 to Figure 26 The embodiment shown in the figure shows an electrical connection method between the multiple first conductive members in the first carrier 12 and the multiple second conductive members in the base. The details are not repeated here. In this way, through the above arrangement, the aperture driving chip 262 can also be electrically connected to the multiple second conductive members in the base through the flexible circuit board 261, the multiple first electrical connectors in the second carrier 21, and the multiple second electrical connectors in the first carrier 12.

[0306] It can be understood that, compared with the solution in which the first aperture coil 231 and the second aperture coil 232 are electrically connected to the first conductive member of the first carrier 12 through the flexible circuit board 261, the first aperture coil 231 of this embodiment can be electrically connected to the first conductive member of the first carrier 12 through the elastic member 263. The structure of the elastic member 263 is relatively simple, and its electrical connection method is also relatively simple, and the cost is low. In addition, the elastic member 263 occupies a small space, which is conducive to the miniaturization of the motor.

[0307] The above describes an implementation method of how to electrically connect the first aperture coil 231 to the second conductive member of the base 11. Fig.22A ) can be electrically connected to the second conductive member of the base 11 by referring to the electrical connection method of the first aperture coil 231. The details will not be repeated here. In other embodiments, the second aperture coil 232 can also be electrically connected to the flexible circuit board 261 through the conductive member in the second carrier 21, and a current loop is formed through the flexible circuit board 261 and the aperture driving chip 262. The aperture driving chip 262 can control the current condition of the second aperture coil 232 (for example, whether current is passed or the magnitude of the current when power is passed, etc.) through the flexible circuit board 261. It can be understood that the first aperture coil 231 and the second aperture coil 232 can be connected in parallel or in series.

[0308] It can be understood that the electrical connection method of the first aperture coil 231 of this embodiment can be combined with the above embodiments to obtain a new embodiment.

[0309] For example, Fig.32 This is a partial structural diagram of another motor 1 provided in an embodiment of the present application. Figure 3 .like Fig.32 As shown, in the present embodiment, the first aperture coil 231 can be electrically connected from the second carrier 21 to the first carrier 12 through the elastic member 263. The structure of the elastic member 263 is relatively simple, and its electrical connection method is also relatively simple and low in cost. The elastic member 263 occupies a small space, which is conducive to the miniaturization of the motor. In addition, the first support member 13 includes a ball 132. In this way, the first carrier 12 is movably connected to the base 11 through the ball 132. Compared with the first support member 13 adopting a sliding shaft structure, on the one hand, the contact area between the first carrier 12 and the ball 132 is smaller, and the friction between the first carrier 12 and the ball 132 is smaller, which is conducive to reducing the loss of the motor 1; on the other hand, the cost of the ball 132 is lower, which is conducive to reducing the cost investment of the motor 1.

[0310] For another example, Fig.33 This is a partial structural diagram of another motor 1 provided in an embodiment of the present application. Figure 4 .like Fig.33As shown, in this embodiment, the first aperture coil 231 can be electrically connected from the second carrier 21 to the first carrier 12 through the elastic member 263. The structure of the elastic member 263 is relatively simple, and its electrical connection method is also relatively simple, and the cost is low. The elastic member 263 occupies a small space, which is conducive to the miniaturization of the motor. In addition, the first support member 13 of this embodiment includes a reed 133. In this way, the first carrier 12 can be movably connected to the base 11 through the reed 133.

[0311] It can be understood that, compared with the first support member 13 adopting the sliding shaft 31 structure, on the one hand, the reed 133 can provide a reset force to the first carrier 12, reducing the power consumption of the first carrier 12 returning to its original position; on the other hand, the cost of the reed 133 is relatively low, which is conducive to reducing the cost investment of the motor 1.

[0312] The fifth implementation mode, the same technical contents as the above implementation modes are not repeated here: Fig.34 This is a partial structural diagram of another motor 1 provided in an embodiment of the present application. Figure 5 . Fig.35 yes Fig.34 A partially exploded schematic diagram of some embodiments of the motor 1 is shown.

[0313] like Fig.34 and Fig.35 As shown, exemplarily, the motor 1 includes a focus module 10 and a variable aperture module 20. The focus module 10 includes a base 11, a first carrier 12, a first support member 13, a focus drive mechanism 14, a first circuit board assembly 15, and a second circuit board assembly 16. In other embodiments, the focus module 10 may not include the first circuit board assembly 15 and / or the second circuit board assembly 16.

[0314] Exemplarily, the focus drive mechanism 14 includes a first focus coil 141, a second focus coil 142, a first focus magnetic member 143, and a second focus magnetic member 144. In other embodiments, the focus drive mechanism 14 may not include the second focus coil 142 and the second focus magnetic member 144.

[0315] It is understandable that the structures of the first circuit board assembly 15 and the second circuit board assembly 16 can refer to the structures of the first circuit board assembly 15 and the second circuit board assembly 16 in the above embodiments, and will not be described in detail here.

[0316] like Fig.35 and Fig.34As shown, the variable aperture module 20 includes a second carrier 21, a second support member 22, an aperture driving mechanism 23, a plurality of blades 24, an upper cover 25, and a third circuit board assembly 26. Exemplarily, the second support member 22 adopts a ball structure. The number of the second support members 22 is four. In other embodiments, the structure and number of the second support members 22 are not specifically limited. In addition, in other embodiments, the variable aperture module 20 may not include the upper cover 25 and / or the third circuit board assembly 26.

[0317] Exemplarily, the aperture driving mechanism 23 includes a first aperture coil 231, a second aperture coil 232, a first aperture magnetic member 233, and a second aperture magnetic member 234. In other embodiments, the aperture driving mechanism 23 may not include the second aperture coil 232 and the second aperture magnetic member 234.

[0318] It is understandable that the structure of the third circuit board assembly 26 can refer to the structure of the third circuit board assembly 26 in each of the above embodiments, and will not be described in detail here.

[0319] Fig.36 yes Fig.34 The diagram shows a partial structure of the motor 1 in one embodiment.

[0320] like Fig.36 As shown, illustratively, the first focusing coil 141 is fixed on the first circuit board assembly 15 and electrically connected to the first circuit board assembly 15. The second focusing coil 142 is fixed on the second circuit board assembly 16 and electrically connected to the second circuit board assembly 16. The first circuit board assembly 15 is fixed to the base 11. The second circuit board assembly 16 is fixed to the base 11.

[0321] In addition, the first focusing magnetic member 143 can be fixed to the first carrier 12. The second focusing magnetic member 144 can be fixed to the first carrier 12. The first carrier 12 is movably connected to the base 11 through the first support member 13. The first focusing coil 141 is arranged facing the first focusing magnetic member 143, and the second focusing coil 142 faces the second focusing magnetic member 144, and is used to drive the first carrier 12 to move along the first direction Z relative to the base 11.

[0322] It can be understood that the basic design of the component structure of the focusing module 10 of this embodiment, the connection relationship design between the components, and the connection relationship design between the components and other structures outside the assembly can all refer to the relevant schemes of the focusing module 10 above, while allowing slight differences in the detailed structure or position arrangement of the components.

[0323] Fig.37 yes Fig.34 The motor 1 is shown in a partial sectional view of an embodiment at EE.

[0324] like Fig.37 As shown, the first aperture coil 231 and the second aperture coil 232 are fixed on the first carrier 12 at intervals. Exemplarily, the first aperture coil 231 and the second aperture coil 232 can be fixed at different positions of the first mounting portion 121 of the first carrier 12 at intervals.

[0325] like Fig.37 As shown, the first aperture magnetic component 233 and the second aperture magnetic component 234 are fixed on the second carrier 21 at intervals.

[0326] Exemplarily, the first aperture magnetic component 233 and the second aperture magnetic component 234 are fixed to the second carrier 21 at intervals. Exemplarily, the first aperture magnetic component 233 is fixed to the first extension portion 212 of the second carrier 21. The second aperture magnetic component 234 is fixed to the second extension portion 213 of the second carrier 21. In one embodiment, the first extension portion 212 is provided with a first receiving groove 2124. The second extension portion 213 is provided with a second receiving groove 2134. The first aperture magnetic component 233 is located in the first receiving groove 2124. The second aperture magnetic component 234 is located in the second receiving groove 2134.

[0327] Exemplarily, the variable aperture module further includes a first aperture magnetic conductive member (not shown) and a second aperture magnetic conductive member (not shown). The first aperture magnetic conductive member and the second aperture magnetic conductive member are fixed on the second carrier 21 at intervals, and the first aperture magnetic conductive member is arranged opposite to the first aperture magnetic member 233, and the second aperture magnetic conductive member is arranged opposite to the second aperture magnetic member 234. The first aperture magnetic conductive member can be used to enhance the magnetic field directivity of the first focusing magnetic member 143. The second aperture magnetic conductive member can be used to enhance the magnetic field directivity of the second focusing magnetic member 144.

[0328] like Fig.37 As shown, the first aperture coil 231 is arranged facing the first aperture magnetic member 233 , and the second aperture coil 232 faces the second aperture magnetic member 234 , and is used to drive the second carrier 21 to rotate relative to the first carrier 12 in the XY plane.

[0329] It is understandable that in the foregoing (e.g. Fig.18), since the first aperture coil 231 and the second aperture coil 232 are fixed on the second carrier 21 at intervals, when the first aperture coil 231 and the second aperture coil 232 are electrically connected to the second conductive member of the base 11, the current paths of the first aperture coil 231 and the second aperture coil 232 need to cross the space between the second carrier 21 and the first carrier 12, and the space between the first carrier 12 and the base 11. Since the second carrier 21 will rotate relative to the first carrier 12 in the XY plane, and the first carrier 12 will move relative to the base 11 along the Z axis, it is necessary to ensure that the current paths of the first aperture coil 231 and the second aperture coil 232 will not be torn off or have unreliable connections during these two relative movements. In this way, the structure of the current paths of the first aperture coil 231 and the second aperture coil 232 is relatively complex. In the present embodiment, the first aperture coil 231 and the second aperture coil 232 are fixed on the first carrier 12 at intervals, so that when the first aperture coil 231 and the second aperture coil 232 are electrically connected to the second conductive member of the base 11, the current path of the first aperture coil 231 and the second aperture coil 232 only needs to cross the space between the first carrier 12 and the base 11, that is, the current path of the first aperture coil 231 and the second aperture coil 232 does not need to cross the space between the second carrier 21 and the first carrier 12. In this way, the structure of the current path of the first aperture coil 231 and the second aperture coil 232 is relatively simple. Therefore, the aperture driving mechanism 23 of the variable aperture module 20 adopts a dynamic magnet solution (that is, the first aperture coil 231 and the second aperture coil 232 are fixed on the first carrier 12 at intervals, and the first aperture magnetic member 233 and the second aperture magnetic member 234 are fixed on the second carrier 21 at intervals), so that the structure of the current path of the first aperture coil 231 and the second aperture coil 232 can be simplified.

[0330] like Fig.37As shown, the third circuit board assembly 26 includes a flexible circuit board 261 and an aperture driving chip 262. The first aperture coil 231 and the aperture driving chip 262 are both fixed on the flexible circuit board 261 and are both electrically connected to the flexible circuit board 261. The input end and the output end of the first aperture coil 231 form a current loop through the flexible circuit board 261 and the aperture driving chip 262. The aperture driving chip 262 can control the current of the first aperture coil 231 (for example, whether the current is passed or the magnitude of the current when the current is passed) through the flexible circuit board 261. In one embodiment, the first aperture coil 231 can be arranged around the aperture driving chip 262. In this way, the aperture driving chip 262 can effectively utilize the inner space of the first aperture coil 231, thereby greatly improving the space utilization rate of the motor 1. In other embodiments, the first aperture coil 231 and the aperture driving chip 262 can also be fixed at other positions of the flexible circuit board 261. Specifically, this application is not limited.

[0331] Exemplarily, the flexible circuit board 261 is fixed on the first carrier 12. At this time, the first aperture coil 231 and the aperture driving chip 262 are fixed on the first carrier 12 through the flexible circuit board 261. It can be understood that the multiple traces (not shown) in the flexible circuit board 261 are electrically connected to the multiple second electrical connectors (not shown) in the first carrier 12 one by one. Among them, the multiple second electrical connectors can be embedded in the first carrier 12. The functions of the multiple traces in the flexible circuit board 261 include being used as a transmission channel for the negative power supply of the aperture driving chip 262, a transmission channel for the positive power supply, a transmission channel for the SDA signal, and a transmission channel for the SCL signal. Among them, the electrical connection method of the multiple second electrical connectors in the first carrier 12 and the multiple second conductive parts of the base can refer to the above various embodiments ( Figure 23 to Figure 26 The electrical connection method of the multiple first conductive members in the first carrier 12 and the multiple second conductive members of the base is shown in the embodiment shown in the figure. The details are not repeated here. In this way, through the above settings, the aperture driving chip 262 can also be electrically connected to the multiple second conductive members of the base through the flexible circuit board 261 and the multiple second electrical connecting members in the first carrier 12. In this way, the structure of the current path of the first aperture coil 231 and the second aperture coil 232 is relatively simple.

[0332] It is understandable that the electrical connection method of the first aperture coil 231 can be referred to for the electrical connection method of the second aperture coil 232 to the second conductive member of the base 11. The details will not be repeated here. In other embodiments, the second aperture coil 232 can also be electrically connected to the flexible circuit board 261 through the conductive member in the first carrier 12, and a current loop is formed through the flexible circuit board 261 and the aperture driving chip 262. The aperture driving chip 262 can control the current condition of the second aperture coil 232 (for example, whether current is passed or the magnitude of the current when power is passed) through the flexible circuit board 261. It is understandable that the first aperture coil 231 and the second aperture coil 232 can be connected in parallel or in series.

[0333] It is understandable that the aperture driving mechanism 23 of the variable aperture module 20 of this embodiment adopts a moving magnet solution and can be combined with the above embodiments to obtain a new embodiment.

[0334] For example, Fig.38 This is a partial structural diagram of another motor 1 provided in an embodiment of the present application. Figure 5 .like Fig.38 As shown, in this embodiment, the aperture driving mechanism 23 of the variable aperture module 20 adopts a moving magnet solution, thereby simplifying the structure of the current path of the first aperture coil 231 and the second aperture coil 232. In addition, the first support member 13 includes a ball 132. In this way, the first carrier 12 is movably connected to the base 11 through the ball 132. Compared with the first support member 13 adopting a sliding shaft structure, on the one hand, the contact area between the first carrier 12 and the ball 132 is smaller, and the friction between the first carrier 12 and the ball 132 is smaller, which is conducive to reducing the loss of the motor 1; on the other hand, the cost of the ball 132 is lower, which is conducive to reducing the cost investment of the motor 1.

[0335] For another example, Fig.39 This is a partial structural diagram of another motor 1 provided in an embodiment of the present application. Figure 6 .like Fig.39 As shown, in this embodiment, the aperture driving mechanism 23 of the variable aperture module 20 adopts a dynamic magnet solution, thereby simplifying the structure of the current path of the first aperture coil 231 and the second aperture coil 232. In addition, the first support member 13 includes a reed 133. In this way, the first carrier 12 can be movably connected to the base 11 through the reed 133.

[0336] It can be understood that, compared with the first support member 13 adopting the sliding shaft 31 structure, on the one hand, the reed 133 can provide a reset force to the first carrier 12, reducing the power consumption of the first carrier 12 returning to its original position; on the other hand, the cost of the reed 133 is relatively low, which is conducive to reducing the cost investment of the motor 1.
