Description

Technical Field

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

[0002] During motor operation, springs are primarily used to power the electronic components of the motor's moving parts. However, in a compact space, the springs cannot be freely extended to create a suspended shape. If the springs deform excessively, the stress in the material can exceed the material threshold, causing the springs to break. Furthermore, as the springs deform, their stiffness (K value) increases nonlinearly with increasing travel. A greater travel increases the K value, hindering the movement of the motor's moving parts. Utility Model Content

[0003] The present application provides a low-K value electrical connector, a motor, a camera module and an electronic device that can be used for long-range power supply.

[0004] In a first aspect, an embodiment of the present application provides a motor. The motor includes a carrier, a base, an electrical connector and a drive unit, and the drive unit is used to drive the carrier to move relative to the base. Along the length direction of the electrical connector, the electrical connector includes a first end, a second end and a first deformation segment, the first deformation segment is fixedly connected between the first end and the second end, the first end is fixedly connected to the base, the second end is fixedly connected to the carrier, and the electronic devices on the carrier are electrically connected. In the first direction, the first deformation segment includes a plurality of electrical connection layers, the electrical connection layers are fixedly connected between the first end and the second end, the plurality of electrical connection layers are spaced apart, and the space between two adjacent electrical connection layers at at least part of the position of the first deformation segment is hollowed out, the first direction is different from the length direction of the electrical connector, and when the carrier moves relative to the base, the first end approaches or moves away from the second end in the first direction.

[0005] It can be understood that, compared to solutions that use glue to securely connect the multiple electrical connection layers of the first deformable section, the present application reduces the K value of the electrical connector by hollowing out the layers within the first deformable section. During motor operation, the carrier moves relative to the base, the first deformable section deforms, and the second end of the electrical connector can move closer to or further away from the first end of the electrical connector in a first direction. The hollowing out of the multiple electrical connection layers along the first deformable section significantly reduces the K value of the electrical connector. A lower K value for the electrical connector reduces its obstruction to the carrier's movement, requiring less driving force from the drive unit to move the carrier, thereby reducing motor power consumption. When the drive unit utilizes a combination of magnets and coils, the magnets and coils can be smaller, resulting in a more compact motor structure. Furthermore, the electrical connector can be used to transmit electrical signals to electronic devices on the carrier. These electronic devices are not limited to the drive unit but can also include other types of devices.

[0006] In one possible implementation, along the length of the electrical connector, the first deformable section includes a first portion and a second portion, with the first portion connected to the second portion. An adhesive layer is provided between adjacent electrical connection layers in the first section to securely connect the two layers. A hollow portion is provided between adjacent electrical connection layers in the second section.

[0007] It is understood that during the carrier's movement, the first deformable section locally provides an adhesive layer between two adjacent electrical connection layers, thereby firmly connecting the two adjacent electrical connection layers and forming the first portion. This effectively prevents the structure from becoming loose due to excessively long delaminated sections. The provision of this first portion is particularly necessary when the carrier undergoes long-range motion relative to the base.

[0008] In a possible implementation manner, the first portion is a bent segment.

[0009] It is understandable that during the movement of the carrier, the bending section deforms more significantly than other sections, and local fixation in the bending section is more conducive to reducing the risk of structural looseness in the first deformed section.

[0010] In a possible implementation, the first deformation section includes a plurality of bending sections, and the plurality of bending sections are arranged along the length direction of the electrical connector.

[0011] It is understood that by providing the bending segments, the length of the first deformable segment can be extended without increasing its X-axis and Y-axis dimensions, further reducing the K value of the electrical connector. When the width in the X-axis and Y-axis directions is limited, providing the first deformable segment with multiple bending segments can increase its length, thereby achieving long-range mobile power supply for the motor within a smaller installation space.

[0012] In one possible implementation, the plurality of bending sections are coplanar. In this way, the first deformable section is smaller in the Z-axis direction, which is conducive to miniaturization of the electrical connector and can be applied in more scenarios.

[0013] In one possible implementation, the first deformation segment includes one or more of a broken line structure, a spiral structure, and a curved structure.

[0014] In one possible implementation, the electrical connection layer includes a conductive layer and an insulating substrate, which are stacked along a first direction. It is understood that the conductive layer can be used to transmit electrical signals, and the insulating substrate can serve as a carrier for the conductive layer.

[0015] In one possible implementation, the position where the first end and the first deformation segment are connected is the first position, the position where the second end and the first deformation segment are connected is the second position, and the length of the first deformation segment is greater than the distance between the first position and the second position.

[0016] It can be understood that the first deformation section can be used to extend the length of the electrical connector and reduce the K value of the electrical connector. When the coil drives the carrier to move, the first deformation section can be stretched and deformed, which is beneficial to reducing the reaction force of the electrical connector on the carrier. It can avoid the second end of the electrical connector falling off from the carrier and disconnecting between the second circuit board due to the carrier's movement path being too long, or the first end of the electrical connector falling off from the base and disconnecting from the first circuit board, which affects the operation of the motor, so that the electrical connection reliability between the electrical connector and the second circuit board is better.

[0017] In a possible implementation, the electrical connector further includes a second deformable segment fixedly connected between the first end and the second end, and the second deformable segment is spaced apart from the first deformable segment and is hollowed out.

[0018] It can be understood that compared with the solution of fixed connection between the first deformation segment and the second deformation segment, the present application hollows out the space between the second deformation segment and the first deformation segment, that is, the electrical connector is further layered and hollowed out in the Z-axis direction (width direction), which can further reduce the K value of the electrical connector.

[0019] In one possible implementation, the electrical connector is a flexible circuit board or a spring.

[0020] In a possible implementation, in the first direction, the K value of the electrical connector is less than or equal to 10 mN / mm.

[0021] It is understandable that by setting the K value of the electrical connector within a smaller range, when the carrier moves along the first direction, the electrical connector will have less obstruction to the movement of the carrier and the motor will consume less power.

[0022] In one possible implementation, the driving unit includes a coil and a magnet unit, one of which is fixedly connected to the carrier, and the other is fixedly connected to the base. The coil faces the magnet unit and is used to drive the carrier to move relative to the base.

[0023] It is understandable that the motor can be driven by the interaction between the energized coil and the magnet unit, and the process is mature and easy to obtain.

[0024] In one possible implementation, the carrier moves relative to the base in a second direction, and the second direction is parallel to or at an acute angle to the first direction, so that the second end of the electrical connector can move closer to or farther from the first end of the electrical connector in the first direction.

[0025] In one possible implementation, the carrier has a bearing surface and a back surface, which are arranged along the second direction. The bearing surface is used to mount a first optical element or a photosensitive element, the second end is fixedly connected to the back surface, and the first deformation section is located on the side of the back surface away from the bearing surface.

[0026] It is understandable that when the carrier moves relative to the base, there will be a larger space on the back side of the carrier, which can be used to accommodate the deformation of the electrical connector, reducing the risk of interference with surrounding devices after the electrical connector is deformed, and the motor has better working reliability.

[0027] In one possible implementation, the base includes a bottom plate, a first side wall, and a second side wall. The first side wall and the second side wall are fixedly connected to the same side of the bottom plate. The first side wall and the second side wall are spaced apart along a third direction, and the third direction and the second direction are arranged at an angle. The bottom plate, the first side wall, and the second side wall enclose a movement space, and the carrier, the coil, and the magnet unit are all located in the movement space. The first end is fixedly connected to a surface of the first side wall that is away from the movement space, or the first end is fixedly connected to a surface of the second side wall that is away from the movement space.

[0028] It can be understood that the first end is fixedly connected to the first side wall or the second side wall, which is convenient and less difficult to install.

[0029] In one possible implementation, the carrier has a bottom surface facing the base plate and connected between the carrier surface and the back surface. The coil is fixedly connected to the bottom surface, and the magnet unit is fixedly connected to the base plate. The motor also includes a second circuit board, a portion of which is fixedly connected to the back surface and electrically connected to the second end, and a portion of which is fixedly connected to the bottom surface and electrically connected to the coil.

[0030] It is understood that when the coil is fixed to the bottom surface of the carrier, the driving force on the carrier is closer to the center of the carrier, which is beneficial to the smooth movement of the carrier. By providing a second circuit board, the fixing position of the second end of the electrical connector and the carrier is less restricted. For example, when the coil is fixed to the bottom surface of the carrier, the second end of the electrical connector does not need to be fixedly connected to the bottom surface of the carrier. The second end of the electrical connector can be fixedly connected to the back surface of the carrier, and the coil is electrically connected via the second circuit board.

[0031] In a second aspect, embodiments of the present application provide a camera module. The camera module includes a photosensitive element, a first optical element, and a motor, wherein the first optical element is located on the light-entering side of the photosensitive element. The first optical element is fixedly connected to a carrier of the motor, or the photosensitive element is fixedly connected to the carrier of the motor.

[0032] It can be understood that during the operation of the motor, the K value of the electrical connector is small, the degree of obstruction of the electrical connector to the movement of the carrier is small, and the driving force required by the driving unit to drive the carrier to move can be smaller, which is beneficial to reducing the power consumption of the camera module; when the driving unit adopts a combination of magnets and coils, the volume of the magnets and coils can be smaller, and the motor structure is more compact, which is beneficial to the miniaturization of the camera module.

[0033] In a third aspect, an embodiment of the present application provides an electronic device, which includes a housing and a camera module, wherein the camera module is mounted on the housing.

[0034] It is understandable that the camera module has low power consumption, which is conducive to longer battery life of electronic devices. The camera module is also small in size, which is conducive to the miniaturization of electronic devices.

[0035] In a fourth aspect, an embodiment of the present application provides an electrical connector. Along the length direction of the electrical connector, the electrical connector includes a first end, a second end, and a first deformation segment, and the first deformation segment is fixedly connected between the first end and the second end. In the first direction, the first deformation segment includes a plurality of electrical connection layers, and the electrical connection layers are fixedly connected between the first end and the second end. The plurality of electrical connection layers are spaced apart, and the space between two adjacent electrical connection layers at at least part of the first deformation segment is hollowed out. The first direction is different from the length direction of the electrical connector. The electrical connector is used for transmitting electrical signals of electronic devices on the carrier of the motor. The first end is fixedly connected to the base of the motor, and the second end is fixedly connected to the carrier of the motor. When the carrier of the motor moves relative to the base of the motor, the first end approaches or moves away from the second end in the first direction.

[0036] It can be understood that, compared to the solution of filling glue between the multiple electrical connection layers of the first deformation section to fix the connection, the present application can reduce the K value of the electrical connector by hollowing out the multiple electrical connection layers included in the first deformation section of the electrical connector. When the electrical connector is used for electrical signal transmission of the motor, during the operation of the motor, the carrier moves relative to the base, the first deformation section is deformed, and the second end of the electrical connector can move closer to or farther away from the first end of the electrical connector in the first direction. The hollowing out between the multiple electrical connection layers arranged along the first direction of the first deformation section can significantly reduce the K value of the electrical connector. The smaller the K value of the electrical connector, the less obstruction the electrical connector has on the movement of the carrier, and the driving force required by the drive unit to drive the carrier to move can be smaller. In addition, the electrical connector can be used for electrical signal transmission of electronic devices on the carrier. The electronic devices are not limited to the drive unit, but can also be other types of devices.

[0037] In one possible implementation, along the length of the electrical connector, the first deformable section includes a first portion and a second portion, with the first portion connected to the second portion. An adhesive layer is provided between adjacent electrical connection layers in the first section to securely connect the two layers. A hollow portion is provided between adjacent electrical connection layers in the second section.

[0038] It is understood that the first deformable section locally provides an adhesive layer between two adjacent electrical connection layers to securely connect them, forming the first portion. This effectively prevents the structure from becoming loose due to excessively long layers. The first portion is particularly necessary when the carrier undergoes long-range motion relative to the base.

[0039] In a possible implementation manner, the first portion is a bent segment.

[0040] It is understandable that during the movement of the carrier, the bending section deforms more significantly than other sections, and local fixation in the bending section is more conducive to reducing the risk of structural looseness in the first deformed section.

[0041] In a possible implementation, the first deformation section includes a plurality of bending sections, and the plurality of bending sections are arranged along the length direction of the electrical connector.

[0042] It is understood that by providing the bending segments, the length of the first deformable segment can be extended without increasing its X-axis and Y-axis dimensions, further reducing the K value of the electrical connector. When the width in the X-axis and Y-axis directions is limited, providing the first deformable segment with multiple bending segments can increase its length, thereby achieving long-range mobile power supply for the motor within a smaller installation space.

[0043] In one possible implementation, the first deformation segment includes one or more of a broken line structure, a spiral structure, and a curved structure.

[0044] In a possible implementation, the electrical connector further includes a second deformable segment fixedly connected between the first end and the second end, and the second deformable segment is spaced apart from the first deformable segment and is hollowed out.

[0045] It can be understood that compared with the solution of fixed connection between the first deformation segment and the second deformation segment, the present application hollows out the space between the second deformation segment and the first deformation segment, that is, the electrical connector is further layered and hollowed out in the Z-axis direction (width direction), which can further reduce the K value of the electrical connector.

[0046] In one possible implementation, the electrical connector is a flexible circuit board or a spring.

[0047] In a possible implementation, in the first direction, the K value of the electrical connector is less than or equal to 10 mN / mm.

[0048] It is understandable that by setting the K value of the electrical connector within a smaller range, when the carrier moves along the first direction, the electrical connector will have less obstruction to the movement of the carrier and the motor will consume less power.

[0089] For ease of understanding, the English abbreviations and related technical terms involved in the embodiments of this application are explained and described below.

[0090] Lens: A lens is a component that uses the principle of refraction to allow light from the scene to pass through the lens and form a clear image on the focal plane. A lens may contain one or more lenses, which can be concave or convex.

[0091] Optical Axis: The direction of light propagation through an optical system, referenced to the principal ray at the center of the field of view. For symmetrical transmissive systems, this axis typically coincides with the axis of rotation of the optical system. For off-axis and reflective systems, the optical axis may also appear as a broken line.

[0092] Focus: Focusing is also called focusing. The process of changing the distance between the subject and the subject using the camera's focus mechanism to achieve a clear image of the subject is called focusing. Digital cameras typically offer a variety of focus modes, including autofocus, manual focus, and multiple focus modes.

[0093] Autofocus: Autofocus uses the principle of light reflection from an object. The reflected light is received by the sensor on the camera (such as a charge-coupled device (CCD)), processed by a computer, and drives the electric focus device to focus. This is called autofocus.

[0094] Halbach magnet: Through the combination of three directional magnets, stronger magnetic thrust performance is obtained, but at the same time the required anti-overturning moment also increases.

[0095] Linear suspension assembly: Trace Suspension Assembly (TSA). A component in which the spring and signal line are integrally molded.

[0096] The embodiments of the present application are described below in conjunction with the accompanying drawings. The embodiments described herein with reference to the accompanying drawings are exemplary and intended to be used to explain the present application, and should not be understood as limiting the present application.

[0097] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. It should be understood that in the present application, "electrical connection" can be understood as the physical contact and electrical conduction of components; it can also be understood as the form in which different components in the circuit structure are connected through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship. For example, A and B are connected or A and B are connected, which means that there is a fastening component (such as a screw, bolt, rivet, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0098] Furthermore, the word "fixed" in this article should also be understood in a broad sense. For example, "fixed" can be directly fixed or indirectly fixed through an intermediate medium. Among them, "fixed" means connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. "Multiple" refers to two or more than two.

[0099] In the description of the embodiments of the present application, unless otherwise specified, “ / ” means or, for example, A / B can mean A or B; “and / or” in the text is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, “multiple” refers to two or more than two.

[0100] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.

[0101] In addition, in the embodiments of the present application, the limitations of the relative position relationship mentioned, such as parallel, perpendicular, aligned, etc., are all for the current state of the art, rather than absolutely strict limitations, and a small amount of deviation is allowed, and it is possible to be approximately parallel, approximately perpendicular, approximately aligned, 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 degrees 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 degrees and 100 degrees.

[0102] Figure 1 It is a structural diagram of an implementation of the electronic device 1000 provided in an embodiment of the present application. Figure 2 yes Figure 1 The electronic device 1000 is shown as a partial cross-sectional view of one embodiment along line AA.

[0103] The electronic device 1000 may be a device with a camera function, such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a video surveillance device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet. Figure 1 The electronic device 1000 in the illustrated embodiment is described by taking a mobile phone as an example.

[0104] like Figure 1 and Figure 2 As shown, the electronic device 1000 may include a camera module 100, a housing 200, and a screen 300. The screen 300 and the camera module 100 may be mounted on the housing 200. The camera module 100 may be a rear camera module 100 or a front camera module 100. This application is described by taking the rear camera module 100 as an example. It should be noted that Figure 1 、 Figure 2 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 affected by the present invention. Figure 1 、 Figure 2 In other embodiments, when the electronic device 1000 is a device of other forms, the electronic device 1000 may not include the screen 300 .

[0105] For ease of description, in this embodiment, the thickness direction of the electronic device 1000 is defined as the X-axis. The length direction of the electronic device 1000 is defined as the Y-axis. The width direction of the electronic device 1000 is defined as the Z-axis. It is understood that the coordinate system setting of the electronic device 1000 can be flexibly set according to specific actual needs.

[0106] In this embodiment, the housing 200 may include a frame 2001 and a back cover 2002. The back cover 2002 is fixedly connected to the frame 2001. For example, the back cover 2002 may be fixedly connected to the frame 2001 by adhesive. The back cover 2002 may also be integrally formed with the frame 2001, that is, the back cover 2002 and the frame 2001 form a single unitary structure.

[0107] Alternatively, the screen 300 can be located on the side of the frame 2001 away from the back cover 2002. In this case, the screen 300 and the back cover 2002 are located on either side of the frame 2001. The screen 300, the frame 2001, and the back cover 2002 together enclose the interior space of the electronic device 1000. The interior space of the electronic device 1000 can be used to house components of the electronic device 1000, such as a battery, a receiver, or a microphone.

[0108] In some embodiments, the screen 300 can be used to display images, etc. The screen 300 can be a flat screen or a curved screen. The display screen of the screen 300 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, or a liquid crystal display (LCD).

[0109] In some embodiments, the electronic device 1000 may further include an image processor 400. The image processor 400 may be located inside the electronic device 1000. The image processor 400 is communicatively connected to the camera module 100, and the image processor 400 is used to obtain image data from the camera module 100 and process the image data. The communication connection between the camera module 100 and the image processor 400 may include data transmission through electrical connection methods such as wiring, or data transmission may be achieved through coupling or the like. It is understandable that the camera module 100 and the image processor 400 may also be communicatively connected through other methods that can achieve data transmission.

[0110] Image processor 400 optimizes and processes digital image signals and transmits the processed signals to screen 300. Image processor 400 can be an image processing chip or a digital signal processing chip. Its function is to promptly and quickly transmit data obtained by the photosensitive chip to the central processing unit and refresh the photosensitive chip. Therefore, the quality of image processor 400 directly affects image quality (such as color saturation and clarity).

[0111] In some embodiments, the electronic device 1000 may further include an analog-to-digital converter 500, which is connected between the camera module 100 and the image processor 400. The analog-to-digital converter 500 is used to convert the signal generated by the camera module 100 into a digital image signal and transmit it to the image processor 400.

[0112] In some embodiments, the electronic device 1000 may further include a memory 600, which is communicatively connected to the image processor 400. The image processor 400 processes the digital image signal and then transmits the image to the memory 600, so that when the image is subsequently needed, the image can be retrieved from the memory 600 and displayed on the screen 300 at any time. In some embodiments, the image processor 400 may further compress the processed digital image signal before storing it in the memory 600 to save space in the memory 600.

[0113] In some embodiments, the electronic device 1000 may further include a battery 700. The battery 700 may provide power to various components of the electronic device 1000. For example, the camera module 100 may be located inside the electronic device 1000. The camera module 100 may be fixedly connected to the side of the screen 300 facing the back cover 2002. The back cover 2002 may be provided with a light hole 2003. The shape of the light hole 2003 is not limited to the shape of the light hole 2003. Figure 1 The light hole 2003 connects the interior of the electronic device 1000 to the exterior of the electronic device 1000. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light hole 2003. The camera module 100 can collect ambient light entering the interior of the electronic device 1000.

[0114] For example, the battery may also be located inside the electronic device 1000 . Figure 1 The battery is indicated by a dotted box.

[0115] In some embodiments, the back cover 2002 may include a light-transmitting lens 2004 , which is mounted on the light-transmitting hole 2003 to allow light to pass through and is dust-proof and waterproof.

[0116] It is understandable that Figure 1The installation position of the camera module 100 of the electronic device 1000 in the illustrated embodiment is merely illustrative, and this application does not impose strict limitations on the installation position of the camera module 100. In some other embodiments, the camera module 100 may also be installed at other locations of the electronic device 1000, for example, the camera module 100 may be installed at the upper middle or upper right corner of the back of the electronic device 1000. In some other embodiments, the electronic device 1000 may include a terminal body and an auxiliary component that can be rotated, moved, or disassembled relative to the terminal body, and the camera module 100 may also be provided on the auxiliary component.

[0117] In some embodiments, the camera module 100 may be a periscope camera module 100 (eg Figure 2 As shown, Figure 2 The optical axis of the camera module 100 is indicated by a dotted line and an arrow. The optical axis direction of the camera module 100 can be in any direction on the YZ plane. In this way, the camera module 100 has a lower height in the X-axis direction and can be better adapted for use in a thin electronic device 1000.

[0118] like Figure 2 As shown, the camera module 100 may include a motor 10, a first optical element 20, and a photosensitive component 30. The first optical element 20 may be located on the light-entering side of the photosensitive component 30. Light can pass through the first optical element 20 and illuminate the photosensitive surface of the photosensitive component 30. The photosensitive component 30 may be used to convert an optical image into an electrical signal, i.e., an analog image signal. The motor 10 may be used to drive the first optical element 20 to move.

[0119] In some embodiments, the camera module 100 may further include a second optical element 40. The second optical element 40 may be located on the light-emitting side of the first optical element 20 and on the light-entering side of the photosensitive element 302. For example, the first optical element 20 may be a prism, and the second optical element 40 may be a lens assembly.

[0120] In some embodiments, the camera module 100 may further include a second optical element 40. The first optical element 20 may be a lens assembly (not shown). The second optical element 40 may be a lens assembly. The second optical element 40 is located on the light-emitting side of the first optical element 20 and on the light-entering side of the photosensitive element 302.

[0121] In some embodiments, the camera module 100 may further include a second optical element 40, a third optical element 50, and a fourth optical element 60. The second optical element 40, the third optical element 50, and the fourth optical element 60 may all be lens groups. The first optical element 20 is a prism (such as Figure 2(As shown). The third optical element 50 and the fourth optical element 60 are both located on the light-entering side of the prism, and the second optical element 40 is located on the light-exiting side of the first optical element 20. A prism can be used to change the direction of the optical axis. For example, a prism can change the direction of the optical axis from parallel to the X-axis to parallel to the Y-axis.

[0122] Exemplarily, the third optical element 50 and the fourth optical element 60 can be spaced apart along the second direction. The optical focal length of the third optical element 50 and the optical focal length of the fourth optical element 60 can be different. The motor 10 can drive the prism to move in the second direction, so that the prism can be arranged relative to the third optical element 50 in the first position, and the prism and the fourth optical element 60 can be arranged relative to each other in the second position. In this way, the third optical element 50 and the second optical element 40 form a set of focusing lens groups, and the fourth optical element 60 and the second optical element 40 form another set of focusing lens groups, and the optical focal lengths of the two sets of focusing lens groups are different. When the camera module 100 has different focusing requirements, the motor 10 can be used to control the prism to move along the Z-axis direction and switch the focusing lens group to meet the focusing requirements of the camera module 100. The embodiment drawings of this article are introduced by taking the first optical element 20 as a prism as an example.

[0123] For example, the photosensitive assembly 30 may include a filter 301 and a photosensitive element 302. The photosensitive element 302 is located on the light-exiting side of the filter 301. Light can sequentially pass through the first optical element 20 and the filter 301 to illuminate the photosensitive surface of the photosensitive element 302. The photosensitive surface of the photosensitive element 302 also serves as the photosensitive surface of the photosensitive assembly 30. The photosensitive element 302 may be located on the light-exiting side of the second optical element 40.

[0124] Photosensitive element 302 can be used to convert light signals into electrical signals. Photosensitive element 302 (also known as an image sensor) can be a semiconductor chip with hundreds of thousands to millions of photodiodes on its surface. When exposed to light, these diodes generate an electrical charge. Photosensitive element 302 can be a charge-coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS). A CCD is made of a highly sensitive semiconductor material and can convert light into electrical charge. A CCD consists of many photosensitive units, typically measured in millions of pixels. When light strikes the surface of a CCD, each photosensitive unit reflects an electrical charge on the component. The signals generated by all the photosensitive units are combined to form a complete image. CMOS devices primarily utilize semiconductors made of silicon and germanium, resulting in the coexistence of N (negatively charged) and P (positively charged) semiconductors within the CCD. The current generated by these two complementary effects can be recorded and interpreted as an image by a processing chip.

[0125] The filter 301 can be used to filter out unnecessary wavelengths in the light, prevent the photosensitive element 302 from generating false colors or ripples, and thus improve its effective resolution and color reproduction. For example, the filter 301 can be an infrared filter 301. In some other embodiments, the camera module 100 can also cancel the separate filter 301 structure, but instead perform surface treatment or material treatment on some optical elements (such as the second optical element 40, the third optical element 50, or the fourth optical element 60) to achieve the filtering function. This application does not strictly limit the specific embodiments of the structural members or structures used to achieve filtering.

[0126] It is understood that the foregoing text illustrates an embodiment of the motor 10 driving the prism to move in the camera module 100 through the accompanying drawings. In other embodiments, the motor 10 can also be used to drive the lens group to move, for example, any one or more of the second optical element 40, the third optical element 50, and the fourth optical element 60, to achieve zooming or focusing of the camera module 100. In other embodiments, the motor 10 can also be used for anti-shake of the camera module 100. For example, the motor 10 can be used to drive the photosensitive element 302 to move to achieve anti-shake of the camera module 100. The following will provide specific examples of the application of the motor 10 in other embodiments through the accompanying drawings, which will not be repeated here.

[0127] It can be understood that the above text illustrates the application of the motor 10 in the periscope camera module 100 through the accompanying drawings. In other embodiments, the motor 10 can be used in an upright camera module 100 (that is, the optical axis direction of the camera module 100 can be parallel to the X-axis direction). The following will provide specific examples through the accompanying drawings and will not be repeated here.

[0128] The above describes in detail the structures of the electronic device 1000 and the camera module 100. The following describes several embodiments of the motor 10 in conjunction with the relevant figures. It should be understood that in the following figures, for simplicity, when identical structures are included in the figures, some may be numbered and some may not, or all may be numbered.

[0129] Figure 3 yes Figure 2 FIG. 1 is a schematic structural diagram of an embodiment of a motor 10 shown in FIG. Figure 4 yes Figure 3 An exploded schematic diagram of an embodiment of the motor 10 is shown in FIG.

[0130] Exemplarily, the motor 10 may include a base 1 , a carrier 2 , a coil 3 , a magnet unit 4 , an electrical connector 5 , a first guide rod 61 , a second guide rod 62 , a tunneling magnetoresistance effect (TMR) sensor 71 , a magnetic grid 72 , and a first circuit board 81 , a second circuit board 82 .

[0131] Figure 5 yes Figure 3 FIG. 1 is a schematic structural diagram of the motor 10 at another angle. Figure 6 yes Figure 5 FIG. 1 is a schematic structural diagram of an embodiment of the structure shown in FIG. 1 at section line BB.

[0132] like Figure 5 and Figure 6 As shown, coil 3 can be fixedly connected to carrier 2. Magnetic unit 4 can be fixedly connected to base 1. Coil 3 can face magnetic unit 4 and be used to drive carrier 2 to move relative to base 1. It should be understood that the plane around which the wire of coil 3 is wound is the winding plane of coil 3. When coil 3 faces m groups of magnetic units 4, it means that the winding plane of coil 3 faces the magnetic units 4.

[0133] It is understood that the coil 3 and the magnet unit 4 may constitute the drive unit of the motor 10, which is used to drive the carrier 2 to move relative to the base 1. In other embodiments, the positions of the coil 3 and the magnet unit 4 may be interchanged, and the magnet unit 4 may be fixedly connected to the carrier 2. The coil 3 may also be fixedly connected to the base 1. Furthermore, the drive unit of the motor 10 may also adopt other embodiments, for example, a piezoelectric plate may be used to drive the carrier 2 to move relative to the base 1.

[0134] For example, the travel of the carrier 2 of the motor 10 relative to the base 1 may be greater than or equal to 1 millimeter (mm). For example, the travel of the carrier 2 of the motor 10 relative to the base 1 may be 1 mm, 2 mm, 3 mm, 5 mm, 9 mm, 10 mm, etc.

[0135] In some embodiments, one end of the electrical connector 5 can be fixed to the base 1, and the other end can be fixed to the carrier 2. The electrical connector 5 can be used to supply power to the device on the carrier 2 or transmit signals. For ease of understanding, the end of the electrical connector 5 fixedly connected to the fixed part (base 1) of the motor 10 is referred to as the first end 51 of the electrical connector 5, and the end of the electrical connector 5 fixedly connected to the moving part (carrier 2) of the motor 10 is referred to as the second end 53 of the electrical connector 5. For example, the first end 51 of the electrical connector 5 can be electrically connected to the controller or battery of the camera module 100, and the second end 53 of the electrical connector 5 can be electrically connected to the coil 3. The electrical connector 5 can be used to supply power to the coil 3.

[0136] Exemplarily, the first end 51 of the electrical connector 5 can be fixedly connected to the base 1 by soldering, BGA welding or laser welding.

[0137] For example, the second end 53 of the electrical connector 5 may be fixedly connected to the carrier 2 by soldering, BGA welding or laser welding.

[0138] Figure 7a yes Figure 4 FIG. 1 is a schematic structural diagram of an embodiment of an electrical connector 5 shown in FIG.

[0139] like Figure 7a As shown, along the length direction of the electrical connector 5, the electrical connector 5 may include a first end 51, a second end 53, and a first deformable section 52. The first deformable section 52 is fixedly connected between the first end 51 and the second end 53. The first deformable section 52 is electrically connected between the first end 51 and the second end 53.

[0140] In some embodiments, the first deformable segment 52 is deformable. When the coil 3 drives the carrier 2 to move, the distance between the first end 51 and the second end 53 changes. The first deformable segment 52 can deform to accommodate the change in distance between the first end 51 and the second end 53, thereby providing power to the coil 3 during movement.

[0141] Exemplarily, the position where the first end 51 is connected to the first deformable segment 52 is the first position, and the position where the second end 53 is connected to the first deformable segment 52 is the second position. When the first end 51 of the electrical connector 5 is fixedly connected to the base 1 and the second end 53 is fixedly connected to the carrier 2, the length of the first deformable segment 52 can be greater than the distance between the first position and the second position. It is understandable that the first deformable segment 52 can be used to extend the length of the electrical connector 5 and reduce the K value of the electrical connector 5. When the coil 3 drives the carrier 2 to move, the first deformable segment 52 can be stretched and deformed, which is beneficial to reducing the reaction force of the electrical connector 5 on the carrier 2. This can prevent the second end 53 of the electrical connector 5 from falling off from the carrier 2 and disconnecting from the second circuit board 82 due to the long movement path of the carrier 2, or the first end 51 of the electrical connector 5 from falling off from the base 1 and disconnecting from the first circuit board 81, which would affect the operation of the motor 10. This ensures that the electrical connection between the electrical connector 5 and the second circuit board 82 is more reliable.

[0142] In some embodiments, the first deformable section 52 may include a bend section 5201. It is understood that by providing the bend section 5201, the length of the first deformable section 52 can be extended without increasing the X-axis / Y-axis dimensions of the first deformable section 52, further reducing the K value of the electrical connector 5. For example, the length of the first deformable section 52 is greater than the distance between the first end 51 and the second end 53.

[0143] In some embodiments, there may be multiple bent segments 5201, and the multiple bent segments 5201 may be arranged in the length direction of the electrical connector 5. It is understood that when the width in the X-axis direction and the Y-axis direction is limited, the first deformable segment 52 can be provided with multiple bent segments 5201 to increase the length of the first deformable segment 52, thereby achieving long-stroke mobile power supply for the motor 10 in a smaller installation space.

[0144] In some embodiments, the multiple bending segments 5201 included in the first deformable segment 52 can be coplanar. That is, the multiple bending segments 5201 can be in the same plane. In this way, the first deformable segment 52 is smaller in the Z-axis direction, which facilitates the miniaturization of the electrical connector 5 and expands its application scenarios.

[0145] Figure 7b yes Figure 7aFIG. 1 is a simplified cross-sectional structural diagram of an embodiment of an electrical connector 5 in a first direction. Figure 8 yes Figure 7a FIG. 1 is a schematic diagram of a partial structure of the electrical connector 5 at another angle. Figure 9 yes Figure 8 FIG. 1 is a partial cross-sectional view of an embodiment of the electrical connector 5 shown in FIG. 1 at the section line CC.

[0146] like Figures 7a to 9 As shown, the electrical connector 5 may include multiple electrical connection layers spaced apart along a first direction. The first direction is different from the length direction of the electrical connector 5. Multiple electrical connection layers means that the number of electrical connection layers can be two or more. The figure uses three electrical connection layers as an example. For example, the electrical connector 5 may include three electrical connection layers spaced apart along the first direction, namely, a first electrical connection layer 54, a second electrical connection layer 55, and a third electrical connection layer 56.

[0147] In some embodiments, along the length direction of the electrical connector 5, the first electrical connection layer 54 may include a first part 541, a second part 542 and a third part 543 connected in sequence; the second electrical connection layer 55 may include a first part 551, a second part 552 and a third part 553 connected in sequence; the third electrical connection layer 56 may include a first part 561, a second part 562 and a third part 563 connected in sequence. The second part 542 of the first electrical connection layer 54, the second part 552 of the second electrical connection layer 55, and the second part 562 of the third electrical connection layer 56 are all capable of deformation.

[0148] In some embodiments, the multiple electrical connection layers (the first portion 541 of the first electrical connection layer 54, the first portion 551 of the second electrical connection layer 55, and the first portion 561 of the third electrical connection layer 56) at the first end 51 of the electrical connector 5 can be fixedly connected by gluing. The multiple electrical connection layers (the third portion 543 of the first electrical connection layer 54, the third portion 553 of the second electrical connection layer 55, and the third portion 563 of the third electrical connection layer 56) at the second end 53 of the electrical connector 5 can be fixedly connected by gluing. For example, the first end 51 of the electrical connector 5 may include the first portion 541 of the first electrical connection layer 54, the first adhesive layer 511, the first portion 551 of the second electrical connection layer 55, the second adhesive layer 512, and the first portion 561 of the third electrical connection layer 56, which are stacked in sequence along the first direction. The first deformable section 52 of the electrical connector 5 includes the second portion 542 of the first electrical connection layer 54, the second portion 552 of the second electrical connection layer 55, and the second portion 562 of the third electrical connection layer 56, which are spaced apart in sequence along the first direction. The second end 53 of the electrical connector 5 may include a third portion 543 of the first electrical connection layer 54, a third adhesive layer 531, a third portion 553 of the second electrical connection layer 55, a fourth adhesive layer 532, and a third portion 563 of the third electrical connection layer 56, which are sequentially stacked along the first direction.

[0149] It is understandable that the stacking of the first end 51 and the second end 53 of the electrical connector 5 in the first direction is not limited to the above five-layer structure, and may include more or fewer layers. This application does not impose any limitation on this.

[0150] like Figure 5 and Figure 6 As shown, the electrical connector 5 can be used to transmit electrical signals of electronic devices on the carrier 2. When the motor 10 is working, the carrier 2 moves relative to the base 1, the first end 51 of the electrical connector 5 is fixedly connected to the base 1, and the second end 53 of the electrical connector 5 is fixedly connected to the carrier 2. The second end 53 of the electrical connector 5 can move closer to or farther away from the first end 51 of the electrical connector 5 in the first direction. When the motor 10 is working, the carrier 2 can move relative to the base 1 in the second direction. It can be understood that the first direction can be parallel to or at an acute angle to the second direction. In this way, the second end 53 of the electrical connector 5 can move closer to or farther away from the first end 51 of the electrical connector 5 in the first direction. Figure 5 In the figure, the first direction is parallel to the second direction as an example.

[0151] like Figures 7a to 9As shown, the first deformable segment 52 may include multiple electrical connection layers 520, which are spaced apart along a first direction. Among the multiple electrical connection layers 520 included in the first deformable segment 52, a hollow space is formed between adjacent electrical connection layers 520. It is understood that a hollow space refers to a hollow space between two electrical connection layers 520, which is filled with air and does not contain any dielectric material with a density greater than air. For example, the first deformable segment 52 may include three electrical connection layers 520, namely, the second portion 542 of the first electrical connection layer 54, the second portion 552 of the second electrical connection layer 55, and the second portion 562 of the third electrical connection layer 56. A hollow space is formed between the second portion 542 of the first electrical connection layer 54 and the second portion 552 of the second electrical connection layer 55, and a first hollow space 521 may be formed between the second portion 542 of the first electrical connection layer 54 and the second portion 552 of the second electrical connection layer 55. The second portion 552 of the second electrical connection layer 55 and the second portion 562 of the third electrical connection layer 56 are hollowed out, and a second hollow gap 522 may be defined between the second portion 552 of the second electrical connection layer 55 and the second portion 562 of the third electrical connection layer 56 .

[0152] For example, the calculation formula of K value is as follows:

[0153]

[0154] Where E is constant, W is width, T is thickness, and L is length.

[0155] It can be understood that when the length and width remain unchanged, the K value is proportional to the cube of the thickness.

[0156] For example, before delamination, the thickness of the electrical connector 5 can be 0.18 mm. After delamination, the thickness D1 of the second portion 542 of the first electrical connection layer 54 can be 0.06 mm, the thickness D2 of the second portion 552 of the second electrical connection layer 55 can be 0.06 mm, and the thickness D3 of the second portion 562 of the third electrical connection layer 56 can be 0.06 mm. The height H1 of the first hollow gap 521 in the first direction is 0.03 mm, and the height H2 of the second hollow gap 522 in the first direction is 0.03 mm. The total thickness of the electrical connector 5 at the delamination position (first deformation section 52) is slightly greater than the sum of the thicknesses of the second portion 542 of the first electrical connection layer 54, the second portion 552 of the second electrical connection layer 55, and the second portion 562 of the third electrical connection layer 56, to ensure reliable insulation protection of the conductive layer 5423.

[0157] For example, the K value of the first deformation segment 52 before delamination is:

[0158]

[0159] The K value of the first deformation segment 52 after layered hollowing is:

[0160]

[0161] K1 is the K value of the second portion 542 of the first electrical connection layer 54 , K2 is the K value of the second portion 552 of the second electrical connection layer 55 , and K3 is the K value of the second portion 562 of the third electrical connection layer 56 .

[0162] Analysis of the K values ​​of the first deformable section 52 before and after the layered hollowing reveals that, while the total thickness of the first deformable section 52 is slightly greater than its unlayered thickness, the K value decreases significantly after the layered hollowing. For example, the total thickness of the first deformable section 52 increases by 0.06 mm, resulting in a K value decrease of over 80%.

[0163] It is understandable that, compared to the solution of filling glue between the multiple electrical connection layers of the first deformable section 52 to fix the connection, by hollowing out the multiple electrical connection layers included in the first deformable section 52 of the electrical connector 5, during the operation of the motor 10, the carrier 2 moves relative to the base 1, the first deformable section 52 deforms, and the second end 53 of the electrical connector 5 can move closer to or farther away from the first end 51 of the electrical connector 5 in the first direction. The hollowing out of the multiple electrical connection layers arranged along the first direction of the first deformable section 52 can significantly reduce the K value of the electrical connector 5. The smaller the K value of the electrical connector 5, the less obstruction the electrical connector 5 poses to the movement of the carrier 2, the smaller the driving force required for the coil 3 to drive the carrier 2 to move, the smaller the volume of the magnetic coil 3, and the more compact the structure of the motor 10.

[0164] In some embodiments, the stiffness (K value) of the electrical connector 5 in the first direction can be less than or equal to 10 millinewtons per millimeter (mN / mm). For example, the K value of the electrical connector 5 can be 0.1 mN / mm, 0.2 mN / mm, 0.5 mN / mm, 0.8 mN / mm, 1.2 mN / mm, 1.5 mN / mm, 2 mN / mm, 4 mN / mm, 6 mN / mm, 7 mN / mm, 10 mN / mm, etc. It is understood that by setting the K value of the electrical connector 5 within a smaller range, when the carrier 2 moves in the first direction, the electrical connector 5 will have less obstruction to the movement of the carrier 2, and the motor 10 will consume less power.

[0165] Exemplarily, in the first direction, a method for measuring the stiffness (K value) of the electrical connector 5 may include: fixing the first end, fixing a force measuring instrument (e.g., a dynamometer) to the second end, and moving the second end relative to the first end in the first direction. Based on the numerical change of the force measuring instrument, a law of force variation with displacement during the movement of the second end 53 relative to the first end 51 in the first direction is obtained: K = F / Δx, where F is the force value detected by the force measuring instrument, and Δx is the displacement of the second end relative to the first end in the first direction. It should be noted that the displacement of the second end relative to the first end in the first direction needs to be within the linear deformation range of the object being measured, that is, when the relative positions of the two ends of the object being measured are within the linear deformation range, the force value varies approximately linearly with the displacement, and the K value remains approximately unchanged. Due to interference or error in the measurement, if the change in the K value does not exceed 10%, it can be considered that the K value remains unchanged.

[0166] In some embodiments, the electrical connector 5 may be a flexible printed circuit (FPC). For example, the electrical connector 5 may be a trace suspend assembly (TSA). It is understood that a TSA is a type of flexible printed circuit board with excellent rigidity. When the electrical connector 5 is partially suspended, it can maintain its preset shape without collapsing, thereby avoiding interference with surrounding devices. In other embodiments, the electrical connector 5 may be a spring, as illustrated below with the accompanying figures.

[0167] The following describes the structure of the various electrical connection layers of the first deformable segment 52, using the second portion 542 of the first electrical connection layer 54 as an example, when the electrical connector 5 is a flexible circuit board. It will be appreciated that the layer structures of the first portion 541 and the third portion 543 of the first electrical connection layer 54 can be the same as or different from those of the second portion 542 of the first electrical connection layer 54.

[0168] Exemplarily, the second portion 542 of the first electrical connection layer 54 may include a coating layer 5421 and a conductive plate 5422 stacked in a first direction. The conductive plate 5422 may include a conductive layer 5423 and an insulating substrate 5424. The conductive layer 5423 is fixedly connected to the surface of the insulating substrate 5424. The conductive layer 5423 and the insulating substrate 5424 may be stacked in the first direction. The conductive layer 5423 may be used to transmit electrical signals. The insulating substrate 5424 may serve as a carrier for the conductive layer 5423. The coating layer 5421 is fixedly connected to the conductive layer 5423 to cover the exposed conductive layer 5423 on the surface of the insulating substrate 5424. It will be understood that the coating layer 5421 and the insulating substrate 5424 may be used together to protect and insulate the conductive layer 5423.

[0169] For example, the conductive layer 5423 may be made of a conductive material for transmitting electrical signals, such as copper or a copper alloy.

[0170] Exemplarily, the coating layer 5421 and the insulating substrate 5424 may be made of insulating materials to achieve insulation of the electrical connection layer. For example, the materials of the coating layer 5421 and the insulating substrate 5424 may include polyimide (PI).

[0171] Illustratively, the cover layer 5421 (CVL) is a mixed laminate of insulating material and adhesive, and has adhesiveness itself. Therefore, when the cover layer 5421 and the conductive plate 5422 are fixedly connected, no additional adhesive is needed.

[0172] For example, the insulating substrate 5424 of the conductive plate 5422 may have a conductive layer 5423 provided on one side or on both sides. When the conductive layer 5423 is provided on both sides of the insulating substrate 5424, the second portion 542 of the first electrical connection layer 54 may include two coating layers 5421. The two coating layers 5421 may respectively fix the conductive layer 5423 on both sides of the insulating substrate 5424, thereby protecting and insulating the conductive layer 5423.

[0173] For example, the conductive plate 5422 may be a flexible resin coated copper (FRCC) substrate or a flexible copper clad laminate (FCCL) substrate.

[0174] For example, the second portion 542 of the first electrical connection layer 54 may include one or more conductive plates 5422. The multiple conductive plates 5422 may be fixedly connected by an adhesive layer (ADH).

[0175] In other embodiments, the second portion 542 of the first electrical connection layer 54 may not be provided with the covering layer 5421 , and the protection and insulation of the conductive layer 5423 can be achieved through the cooperation of the insulating substrate 5424 in the multiple conductive plates 5422 .

[0176] It is understood that the structures of the second electrical connection layer 55 and the third electrical connection layer 56 can be set with reference to the structure of the first electrical connection layer 54. The first electrical connection layer 54, the second electrical connection layer 55, and the third electrical connection layer 56 can include the same or different numbers of coating layers and conductive plates, and the types of conductive plates can be the same or different. Those skilled in the art can design according to their needs, and this application does not impose any restrictions.

[0177] It is understandable that the thickness of the second portion 542 of the first electrical connection layer 54 , the thickness of the second portion 552 of the second electrical connection layer 55 , and the thickness of the second portion 562 of the third electrical connection layer 56 may be the same or different.

[0178] Table 1 below is an example of the stacked structure of the first deformable segment 52 in the first direction:

[0179] Table 1

[0180]

[0181] As shown in Table 1, the second portion 542 of the first electrical connection layer 54 may include a coating layer 5421 (CVL), two conductive plates 5422 (FRCC and single-sided FCCL), and the two conductive plates 5422 are fixedly connected by an adhesive layer (ADH). The second portion 552 of the second electrical connection layer 55 may include two coating layers (CVL), a conductive plate (double-sided FCCL), and the conductive plate (double-sided FCCL) is connected between the two coating layers (CVL). The second portion 562 of the third electrical connection layer 56 may include two conductive plates (single-sided FCCL and FRCC), and the two conductive plates are fixedly connected by an adhesive layer (ADH). Among them, the conductive layer of one conductive plate can be removed, leaving an insulating substrate (PI) for protection and insulation of the conductive layer of the other conductive plate.

[0182] Illustratively, the second portion 542 of the first electrical connection layer 54 has a thickness of 67 μm in the first direction; the second portion 552 of the second electrical connection layer 55 has a thickness of 75 μm in the first direction; and the second portion 562 of the third electrical connection layer 56 has a thickness of 39.5 μm in the first direction.

[0183] In some embodiments, the first end 51 and the second end 53 of the first electrical connector 5 may be coplanar or not. For example, it is understood that during the process of the electrical connector 5 providing mobile power to the motor 10, the fixed position of the first end 51 of the electrical connector 5 on the base 1 and the fixed position of the second end 53 of the electrical connector 5 on the carrier 2 can be adjusted as needed.

[0184] The following describes in detail several application implementations of the electrical connector 5 in the motor 10 with reference to the accompanying drawings.

[0185] Figure 10 yes Figure 4 FIG2 is a schematic diagram of an assembly of the base 1, the first guide rod 61 and the first circuit board 81 according to an embodiment of the present invention. Figure 11 yes Figure 4 FIG2 is a schematic diagram of an assembly of a base 1, a second guide rod 62, and a magnetic grid 72 according to an embodiment of the present invention.

[0186] like Figure 10 and Figure 11 As shown, the base 1 may include a bottom plate 11, a first side wall 12, a second side wall 13, a first supporting portion 14, a second supporting portion 15, a third supporting portion 16, and a fourth supporting portion 17. The first side wall 12, the second side wall 13, the first supporting portion 14, the second supporting portion 15, the third supporting portion 16, and the fourth supporting portion 17 may be fixed to the same side of the bottom plate 11. The first side wall 12, the second side wall 13, the first supporting portion 14, the second supporting portion 15, the third supporting portion 16, and the fourth supporting portion 17 may be fixed to the periphery of the bottom plate 11.

[0187] In some embodiments, the base plate 11 may include a top surface 111 and a bottom surface 112 disposed opposite each other. The first circuit board 81 may be fixed to the bottom surface 112 of the base plate 11. The first side wall 12, the second side wall 13, the first supporting portion 14, the second supporting portion 15, the third supporting portion 16, and the fourth supporting portion 17 may be fixed to the top surface 111 of the base plate 11. For example, the base plate 11 may be provided with a through hole 113 that passes through the top surface 111 and the bottom surface 112 of the base plate 11. The first circuit board 81 may be partially fixed to the bottom surface 112 of the base plate 11, and the first circuit board 81 and the wall surface of the through hole 113 may enclose a mounting groove 114.

[0188] In some embodiments, the first circuit board 81 may be a printed circuit board (PCB), a flexible circuit board, or a rigid-flexible circuit board.

[0189] In some embodiments, the first supporting portion 14 and the second supporting portion 15 may be arranged opposite each other and spaced apart along the second direction. The third supporting portion 16 and the fourth supporting portion 17 may be arranged opposite each other and spaced apart along the second direction. The first supporting portion 14 and the third supporting portion 16 may be arranged opposite each other and spaced apart along the third direction. The second supporting portion 15 and the fourth supporting portion 17 may be arranged opposite each other and spaced apart along the third direction. The third direction is different from both the first and second directions. The figure illustrates an example in which the second direction is parallel to the Z-axis and the third direction is parallel to the Y-axis.

[0190] In some embodiments, the first guide rod 61 and the second guide rod 62 can be fixed to the base 1 at intervals along the third direction. The length direction of the first guide rod 61 is parallel to the second direction. The length direction of the second guide rod 62 can also be parallel to the second direction. For example, the two ends of the first guide rod 61 can be fixed to the first bearing portion 14 and the second bearing portion 15, respectively. The two ends of the second guide rod 62 can be fixed to the third bearing portion 16 and the fourth bearing portion 17, respectively. For example, the first bearing portion 14 can be provided with a first through hole 141. The second bearing portion 15 can be provided with a second through hole 151. The third bearing portion 16 can be provided with a third through hole 161. The fourth bearing portion 17 can be provided with a fourth through hole 171. The two ends of the first guide rod 61 are respectively fixed in the first through hole 141 and the second through hole 151. The two ends of the second guide rod 62 are respectively fixed in the third through hole 161 and the fourth through hole 171.

[0191] In some embodiments, the first sidewall 12 and the second sidewall 13 can be fixed to the base plate 11 at intervals along a third direction. The third direction and the second direction are arranged at an angle. For example, the first sidewall 12 can be connected between the first support portion 14 and the second support portion 15. The second sidewall 13 can be connected between the third support portion 16 and the fourth support portion 17. The base plate 11, the first sidewall 12, the second sidewall 13, the first support portion 14, the second support portion 15, the third support portion 16, and the fourth support portion 17 can collectively enclose a movement space 18. It is understood that the first support portion 14, the second support portion 15, the third support portion 16, and the fourth support portion 17 can be selectively provided as needed. For example, if the motor 10 does not have the first guide rod 61 and the second guide rod 62, the first support portion 14, the second support portion 15, the third support portion 16, and the fourth support portion 17 can be omitted. In this case, the base plate 11, the first sidewall 12, and the second sidewall 13 can collectively enclose the movement space 18.

[0192] In some embodiments, the bottom plate 11, the first side wall 12, the second side wall 13, the first load-bearing portion 14, the second load-bearing portion 15, the third load-bearing portion 16, and the fourth load-bearing portion 17 can be an integral structural member. The fact that two components are formed into an integral structural member through an integral molding process means that during 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 through further processing (such as bonding, welding, snap connection, or screw connection). For example, the bottom plate 11, the first side wall 12, the second side wall 13, the first load-bearing portion 14, the second load-bearing portion 15, the third load-bearing portion 16, and the fourth load-bearing portion 17 can be integrally formed through a mold injection molding process.

[0193] In some embodiments, the magnetic grid 72 can be fixed to the side of the first side wall 12 or the second side wall 13 facing the movement space 18. For example, the magnetic grid 72 can be fixed to the second side wall 13. In other embodiments, the magnetic grid 72 can also be fixed to the top surface 111 of the bottom plate 11.

[0194] In some embodiments, the magnetic grid 72 may include a plurality of magnets with a polarity direction of N (north) and a plurality of magnets with a polarity direction of S (south). The plurality of N-pole magnets and the plurality of S-pole magnets may be alternately arranged in sequence along the second direction to form a periodically varying magnetic field.

[0195] Figure 12 yes Figure 4 FIG. 1 is a schematic assembly diagram of a base 1 and a magnet unit 4 according to an embodiment of the present invention.

[0196] like Figure 12 As shown, the magnet unit 4 can be fixed to the base 1. For example, the magnet unit 4 can be fixedly connected to the bottom plate 11 of the base 1. Exemplarily, the magnet unit 4 can be fixedly connected to the first circuit board 81 and located in the mounting groove 114. In this way, the height of the camera module 100 in the X-axis direction can be reduced.

[0197] In other embodiments, the magnet unit 4 may also be fixed on the first side wall 12 or the second side wall 13 of the base 1 .

[0198] In some embodiments, the number of the magnetic unit 4 can be one or more. The multiple magnetic units 4 can be arranged in sequence along the second direction. The multiple magnetic units 4 can form multiple magnetic fields arranged along the second direction.

[0199] In some embodiments, the magnet unit 4 may include one or more magnets. For example, the magnet unit 4 may include a first magnet 41 and a second magnet 42. The first magnet 41 and the second magnet 42 may be arranged along the second direction, and the polarity direction of the first magnet 41 may be opposite to the polarity direction of the second magnet 42. The polarity of one of the first magnet 41 and the second magnet 42 may be the north pole (N pole), and the polarity of the other may be the south pole (S pole). The polarity direction of the first magnet 41 may intersect with the polarity direction of the second magnet 42 in the second direction. The sum of the length of the first magnet 41 in the second direction and the length of the second magnet 42 in the second direction is k.

[0200] It is understood that the arrangement direction of the first magnet 41 and the second magnet 42 may not be completely parallel to the arrangement direction of the multiple groups of magnet units 4. The arrangement direction of the first magnet 41 and the second magnet 42 may have a small angle with the arrangement direction of the multiple groups of magnet units 4, and the angle may be less than or equal to 10°. For example, the angle may be 2°, 3°, 5°, or 8°.

[0201] In some embodiments, the length of the first magnet 41 in the second direction can be the same as the length of the second magnet 42 in the second direction. For example, the length of the first magnet 41 in the second direction can be 0.5 k. In this way, the magnetic field of the multiple groups of magnet units 4 is more evenly distributed along the second direction.

[0202] In some embodiments, the magnet unit 4 may include a first magnet 41, a second magnet 42, and a third magnet 43. The first magnet 41, the second magnet 42, and the third magnet 43 may be arranged along the second direction. The third magnet 43 may be located between the first magnet 41 and the second magnet 42. The polarity direction of the first magnet 41 may be opposite to the polarity direction of the second magnet 42. The polarity directions of the first magnet 41, the second magnet 42, and the third magnet 43 are all different. The polarity direction of the first magnet 41 may intersect with the polarity direction of the second magnet 42. The sum of the length of the first magnet 41 in the second direction, the length of the second magnet 42 in the second direction, and the length of the third magnet 43 in the second direction is k.

[0203] In this way, the first magnet 41, the second magnet 42 and the third magnet 43 can form a Halbach magnet array. It can be understood that compared with a magnet array with only north and south pole magnets, the magnetic field strength near the magnets of the Halbach magnet array is stronger.

[0204] like Figure 12 As shown, the first magnet 41 and the second magnet 42 in one group of magnet units 4 form an NS magnetic field, and also form an NS magnetic field with the adjacent magnet units 4. In this way, multiple NS magnetic fields arranged along the second direction constitute the magnetic fields of multiple groups of magnet units 4.

[0205] In other embodiments, the magnetic unit 4 may also be composed of a single magnet, and the magnet includes two parts with opposite polarity directions. The length of the magnet in the first direction is k.

[0206] Figure 13 yes Figure 4 A schematic structural diagram of an embodiment of the carrier 2 is shown in FIG. Figure 14 yes Figure 13 FIG. 1 is a schematic structural diagram of the carrier 2 at another angle.

[0207] like Figure 13 and Figure 14As shown, the carrier 2 can be used to mount the first optical element 20. The carrier 2 includes a carrying surface 21, a bottom surface 22, a first side surface 23, a second side surface 24, and a back surface 25. The carrying surface 21, the bottom surface 22, and the back surface 25 are all connected between the first side surface 23 and the second side surface 24. The bottom surface 22 is connected between the carrying surface 21 and the back surface 25. The carrying surface 21 can be arranged opposite to the bottom surface 22. The carrying surface 21 can be used to mount the first optical element 20 (such as Figure 2 shown).

[0208] It is understood that the shape of the carrier 2 can be designed based on the shape of the first optical element 20. For example, when the first optical element 20 is a prism, the carrier surface 21 can be an inclined surface to match the shape of the prism. The light-reflecting surface of the prism can be fixed to the carrier surface 21.

[0209] In other embodiments, when the first optical element 20 is a lens group, the carrier 2 can be used to mount the lens group. The lens group can be fixed on the carrying surface 21. In this case, the shape of the carrier 2 can be designed according to the specific shape of the lens group, and this application does not limit Figure 13 and Figure 14 The shape of the carrier 2 is shown.

[0210] Figure 15 yes Figure 4 FIG. 1 is a schematic diagram of an assembly of a carrier 2 , a second circuit board 82 , and a tunnel magnetoresistive effect sensor 71 according to an embodiment of the present invention. Figure 16 yes Figure 4 FIG. 8 is a schematic diagram of an assembly of a carrier 2 , a coil 3 , a second circuit board 82 , and a tunnel magnetoresistive effect sensor 71 according to an embodiment of the present invention.

[0211] like Figure 15 and Figure 16 As shown, the coil 3 can be fixed to the bottom surface 22 of the carrier 2. The tunneling magnetoresistance effect (TMR) sensor 71 can be fixed to the second side surface 24 of the carrier 2. It can be understood that when the coil is fixed to the bottom surface 22 of the carrier 2, the driving force on the carrier 2 is closer to the center of the carrier 2, which is conducive to the smooth movement of the carrier 2.

[0212] For example, the number of coils 3 can be one or more. When there are multiple coils 3, the multiple coils 3 can be arranged along the second direction. The currents of the multiple coils 3 can be the same, or multiple coils 3 can be supplied with multi-phase current to drive the carrier 2 to move.

[0213] In some embodiments, a second circuit board 82 can be fixed to the carrier 2 and electrically connected to the coil 3 and the TMR sensor 71. The second circuit board 82 can be used to power the coil 3 and the TMR sensor 71. For example, a portion of the second circuit board 82 can be fixedly connected to the bottom surface 22 of the carrier 2 and electrically connected to the coil 3; a first portion can be fixedly connected to the back surface 25 of the carrier 2; and a portion can be fixedly connected to the second side surface 24 of the carrier 2 and electrically connected to the TMR sensor 71.

[0214] In some embodiments, the second circuit board 82 may be a printed circuit board (PCB), a flexible circuit board, or a rigid-flexible circuit board.

[0215] In some embodiments, the second circuit board 82 may be a flexible circuit board or a rigid-flex circuit board.

[0216] Figure 17 yes Figure 5 FIG. 1 is a schematic structural diagram of an embodiment of the structure shown in FIG. 1 at section line DD.

[0217] like Figure 5 、 Figure 6 and Figure 17 As shown, the bottom surface 22 of the carrier 2 may face the bottom plate 11 of the base 1 . In this way, the coil 3 may face the magnet unit 4 .

[0218] For example, the first end 51 of the electrical connector 5 can be electrically connected to the first circuit board 81. The first circuit board 81 can be electrically connected to the battery 700 and the controller of the camera module 100. The electrical connector 5 can be connected to the battery 700 (such as Figure 1 ), and electrical connections to components such as the controller of the camera module 100. For example, a portion of the first circuit board 81 can be fixedly connected to a surface of the second side wall 13 of the base 1 that is away from the movement space 18. The first end 51 of the electrical connector 5 can be fixedly connected to a surface of the second side wall 13 of the base 1 that is away from the movement space 18 and electrically connected to the first circuit board 81.

[0219] It is understandable that by providing the first circuit board 81, the first end 51 of the electrical connector 5 and the base 1 are less restricted in their fixed positions. Figure 1 As shown), when the controller of the camera module 100 and other devices need to be electrically connected to the motor 10 on one side of the first side wall 12 of the base 1, a portion of the first circuit board 81 can be fixedly connected to the first side wall 12 of the base 1 and electrically connected to the battery 700 (as shown). Figure 1As shown), the controller of the camera module 100 and other devices. The first end 51 of the electrical connector 5 can be fixedly connected to the second side wall 13 of the base 1 and electrically connected to the portion of the first circuit board 81 that is fixedly connected to the second side wall 13 of the base 1. In this way, the electrical connector 5 can be electrically connected to the battery 700 (as shown) through the first circuit board 81. Figure 1 As shown), controller of camera module 100 and other devices.

[0220] In other embodiments, a portion of the first circuit board 81 may be fixedly connected to a surface of the first side wall 12 of the base 1 away from the movement space 18. The first end 51 of the electrical connector 5 may also be fixedly connected to a surface of the first side wall 12 of the base 1 away from the movement space 18.

[0221] In some embodiments, the first end 51 of the electrical connector 5 can be electrically connected to the first circuit board 81 by soldering. In other embodiments, the first end 51 of the electrical connector 5 can also be electrically connected to the first circuit board 81 by ball grid array (BGA) soldering.

[0222] In some embodiments, the second end 53 of the electrical connector 5 can be electrically connected to the second circuit board 82. The second circuit board 82 can electrically connect the coil 3 and the TMR sensor 71. The electrical connector 5 can be electrically connected to the coil 3, the TMR sensor 71, and other devices through the second circuit board 82. For example, a portion of the second circuit board 82 can be fixedly connected to the back surface 25 of the carrier 2. The second end 53 of the electrical connector 5 can be fixedly connected to the back surface 25 of the carrier 2 and electrically connected to the second circuit board 82. It can be understood that by providing the second circuit board 82, the fixed position of the second end 53 of the electrical connector 5 and the carrier 2 is less restricted. For example, when the coil 3 is fixed to the bottom surface 22 of the carrier 2, the second end 53 of the electrical connector 5 does not need to be fixedly connected to the bottom surface 22 of the carrier 2. The second end 53 of the electrical connector 5 can be fixedly connected to the back surface 25 of the carrier 2 and electrically connected to the coil 3 through the second circuit board 82.

[0223] In some embodiments, the second end 53 of the electrical connector 5 can be electrically connected to the second circuit board 82 by soldering. In other embodiments, the second end 53 of the electrical connector 5 can also be electrically connected to the second circuit board 82 by BGA soldering.

[0224] In some embodiments, the bearing surface 21 and the back surface 25 can be arranged along the second direction, with the bearing surface 21 being used to mount the first optical element 20. The second end 53 of the electrical connector 5 can be fixedly connected to the back surface 25 of the carrier 2. The first deformable section 52 of the electrical connector 5 can be located on the side of the back surface 25 of the carrier 2 away from the bearing surface 21. It will be understood that when the carrier 2 moves relative to the base 1, a larger space will be available on the side of the back surface 25 of the carrier 2 to accommodate the deformation of the electrical connector 5, thereby reducing the risk of interference with surrounding devices after deformation of the electrical connector 5, and improving the operating reliability of the motor 10.

[0225] It is understood that when the carrier 2 moves relative to the base 1 in the second direction, the second end 53 of the electrical connector 5 can move in the second direction. The second end 53 of the electrical connector 5 can move relative to the first end 51 of the electrical connector 5 in the second direction. The second direction is parallel to the first direction or is arranged at an acute angle. In this way, the second end 53 of the electrical connector 5 can move closer to or farther away from the first end 51 of the electrical connector 5 in the first direction.

[0226] For example, Figure 5 As shown, when the carrier 2 is in the initial position (the initial position refers to the position of the carrier 2 when the motor 10 is not working), the first deformation section 52 of the electrical connector 5 includes multiple bending sections 5201 that are coplanar, and the plane where the multiple bending sections 5201 are located is the first plane. The first direction can be perpendicular to the first plane. The second end 53 of the electrical connector 5 can also be in the first plane. During the operation of the motor 10, the carrier 2 can move from the initial position to other positions, or return to the initial position from other positions. As the carrier 2 moves, the second end 53 of the electrical connector 5 and the multiple bending sections 5201 gradually leave the first plane, and the multiple bending sections 5201 are not coplanar; or, the second end 53 of the electrical connector 5 and the multiple bending sections 5201 gradually return to the first plane. In other words, during the movement of the carrier 2 relative to the base 1, the second end 53 of the electrical connector 5 can move away from the plane (first plane), and the second end 53 of the electrical connector 5 can move closer to or farther away from the first end 51 of the electrical connector 5 in the first direction.

[0227] In some embodiments, the TMR sensor 71 can be arranged opposite the magnetic grid 72. It is understood that the TMR sensor 71 can cooperate with the magnetic grid 72 to measure the displacement of the carrier 2 when it moves in the first direction. During the movement of the carrier 2, the movement displacement information of the carrier 2 can be fed back to the controller (not shown) that controls the camera module 100. The controller can then detect the displacement of the carrier 2 based on the TMR electrical signal and adjust the current flowing into the coil 3. The TMR sensor 71 has the advantages of high precision, high sensitivity, low power consumption, small size, good temperature stability, and a wide operating temperature range.

[0228] In some embodiments, the electrical connector 5 can be used to transmit electrical signals between the coil 3 and the TMR sensor 71. For example, the electrical connector 5 can be used to transmit the current of the battery to the coil 3 and the TMR sensor 71 to achieve power supply. The electrical connector 5 can also be used to transmit electrical signals between the TMR sensor 71 and the controller of the camera module 100, so that the controller can detect the displacement of the carrier 2 based on the TMR electrical signal and adjust the current flowing into the coil 3. In other embodiments, other electronic devices (not shown) can also be provided on the carrier 2, such as capacitors, resistors, etc.

[0229] It is understandable that the first end 51 of the electrical connector 5 can be electrically connected to more devices, specifically depending on the electrical signals that need to be transmitted by the structural components on the carrier 2. The second end 53 of the electrical connector 5 can also be electrically connected to other devices, not limited to the coil 3 and TMR sensor 71 shown in the embodiment of the present application, specifically depending on the type of electronic device on the carrier 2.

[0230] In some embodiments, the same contents as in the previous embodiments are not repeated. Figure 18 yes Figure 5 FIG. 1 is a simple schematic diagram of an embodiment of the connection relationship among the electrical connector 5 , the base 1 and the carrier 2 . Figure 19 yes Figure 18 Schematic diagram of another embodiment of the structure shown in . Figure 20 yes Figure 18 It is understood that, Figures 18 to 20 Both Figure 5 The diagram shows the relative positional relationship between the back surface 25 of the carrier 2, the first end 51 of the electrical connector 5, and the second end 53 of the electrical connector 5, as shown in the positive direction of the Z axis. Figure 5 The relative position relationship between the base 1 and the carrier 2 is roughly referred to in the figure.

[0231] like Figure 5 and Figure 18 As shown, the second end 53 of the electrical connector 5 is connected to the middle of the back side 25 of the carrier 2, and the first end 51 of the electrical connector 5 is connected to the side of the base 1; or, the second end 53 of the electrical connector 5 is connected to the side of the carrier 2, and the first end 51 of the electrical connector 5 is connected to the middle of the base 1.

[0232] like Figure 5 and Figure 19 As shown, the first end 51 and the second end 53 of the electrical connector 5 can be connected to the side surface of the carrier 2 and the side surface of the base 1 respectively.

[0233] like Figure 5 and Figure 20As shown, the first end 51 and the second end 53 of the electrical connector 5 can be connected to the back surface 25 of the carrier 2 and the middle of the base 1 respectively.

[0234] In some embodiments, the same contents as in the previous embodiments are not repeated. Figure 21 yes Figure 4 FIG. 1 is a schematic structural diagram of another embodiment of the electrical connector 5 shown in FIG. Figure 22 yes Figure 21 FIG2 is a partial cross-sectional view of an embodiment of an electrical connector 5 at position EE. In this embodiment, for ease of description, the direction from the second end 53 of the electrical connector 5 to the first end 51 of the electrical connector 5 is defined as the X-axis, the thickness direction of the electrical connector 5 is defined as the Y-axis, and the Z-axis is perpendicular to the X-axis and Y-axis directions.

[0235] like Figure 21 and Figure 22 As shown, the electrical connector 5 can be a spring. For example, along the length of the electrical connector 5, the electrical connector 5 can include a first end 51, a second end 53, and a first deformable section 52. The first deformable section 52 is fixedly connected to the first end 51 and the second end 53. The first deformable section 52 is electrically connected between the first end 51 and the second end 53.

[0236] Exemplarily, the first deformable segment 52 may include multiple electrical connection layers, spaced apart along a first direction. A hollow space is formed between any two adjacent electrical connection layers within the first deformable segment 52. Exemplarily, the first deformable segment 52 may include three electrical connection layers 520: a first electrical connection layer 520, a second electrical connection layer 520, and a third electrical connection layer 520. A first hollow space 521 is defined between the first electrical connection layer 520 and the second electrical connection layer 520, and a second hollow space 522 is defined between the second electrical connection layer 520 and the third electrical connection layer 520.

[0237] For example, the material used for the first electrical connection layer 520 may include one or more of copper-nickel-tin alloy and titanium-copper alloy. The materials used for the second and third electrical connection layers 520 may refer to the material used for the first electrical connection layer 520.

[0238] It is understandable that in conventional technical solutions, to reduce the K value of the reed, the thickness of the reed is reduced, but this increases the resistance of the reed. In this embodiment, when the electrical connector 5 is a reed, the first deformable section 52 is layered and hollowed out, which is equivalent to connecting several reeds in parallel. This does not increase the resistance, but also reduces the K value.

[0239] In some embodiments, the first deformable section 52 of the electrical connector 5 may include a plurality of bent sections 5201. The plurality of bent sections 5201 may be sequentially connected in the lengthwise extension direction of the electrical connector 5. In this way, the electrical connector 5 may be formed into any spline curve shape.

[0240] In some embodiments, the same contents as in the previous embodiments are not repeated. Figure 23 yes Figure 4 FIG. 1 is a structural diagram of another embodiment of the electrical connector 5 shown in FIG. Figure 24 yes Figure 4 is a schematic structural diagram of another embodiment of the electrical connector 5. In this embodiment, for ease of description, the direction from the second end 53 of the electrical connector 5 to the first end 51 of the electrical connector 5 is defined as the X-axis, the thickness direction of the electrical connector 5 is defined as the Y-axis, and the Z-axis is perpendicular to the X-axis and Y-axis directions.

[0241] like Figures 21 to 24 As shown, the first deformation section 52 of the electrical connector 5 may include a plurality of bending sections 5201, and the plurality of bending sections 5201 may be sequentially connected along the length extension direction of the electrical connector 5, or the plurality of bending sections 5201 may also be provided with a straight section 5202 between two adjacent bending sections 5201 (e.g., Figure 23 As shown in FIG, the two bending sections 5201 can be spaced apart along the length extension direction of the electrical connector 5.

[0242] It is understandable that the combination of multiple bending segments 5201 allows the first deformation segment 52 to have different structural forms. For example, the first deformation segment 52 may include Figure 7a or Figure 24 Alternatively, the first deformation section 52 may include a spiral structure as shown; Figure 21 Alternatively, the first deformation segment 52 may include any spline curve structure shown in FIG. Figure 23 It is understood that the shape of the first deformable segment 52 can be designed according to actual needs, and the first deformable segment 52 can include one or more of a broken line structure, a spiral structure, and a curved structure, which is not limited in this application.

[0243] Illustratively, the broken line structure may include, but is not limited to: a continuous "S" structure, a continuous "V" structure, a continuous "M" structure, a continuous "N" structure, a continuous "W" structure, and the like.

[0244] In other embodiments, the number of the bending section 5201 of the electrical connector 5 may be one, or it may not be provided.

[0245] In some embodiments, the first end 51, the first deformation section 52 and the second end 53 of the electrical connector 5 may also be on the same plane (eg Figures 21 to 24 The electrical connector 5 may be in the shape of a plate or a long sheet.

[0246] In some embodiments, the same contents as in the previous embodiments are not repeated. Figure 25 yes Figure 4 is a schematic structural diagram of another embodiment of the electrical connector 5. In this embodiment, for ease of description, the direction from the second end 53 of the electrical connector 5 to the first end 51 of the electrical connector 5 is defined as the X-axis, the thickness direction of the electrical connector 5 is defined as the Y-axis, and the Z-axis is perpendicular to the X-axis and Y-axis directions.

[0247] It is understood that the electrical connector 5 may be as follows Figure 15 、 Figure 21 、 Figure 23 or Figure 24 The single-line structure shown can also be as follows Figure 25 The multi-line structure shown.

[0248] like Figure 25 As shown, the electrical connector 5 may further include a second deformable section 57. The second deformable section 57 is fixedly connected between the first end 51 and the second end 53, and electrically connects the first end 51 and the second end 53. The second deformable section 57 and the first deformable section 52 are spaced apart and hollowed out. The electrical connector 5 is not limited to the following. Figure 25 The two deformable segments (the first deformable segment 52 and the second deformable segment 57) shown can also be more than two deformable segments, which is not limited in this application. When the electrical connector 5 includes multiple deformable segments, the multiple deformable segments can be spaced and hollowed out.

[0249] It is understandable that the second deformation section 57 may also include a plurality of electrical connection layers that are hollowed out at intervals. The number of electrical connection layers included in different deformation sections may be different. For example, Figure 25 , the electrical connector 5 includes a first deformable segment 52 and a second deformable segment 57 , wherein the second deformable segment 57 includes two electrical connection layers 520 , and the first deformable segment 52 may include three electrical connection layers 520 .

[0250] Figure 7b and Figure 25As shown, the first electrical connection layer 54 may further include a fourth portion 544. The fourth portion 544 of the first electrical connection layer 54 may be fixedly connected between the first portion 541 of the first electrical connection layer 54 and the third portion 543 of the first electrical connection layer 54. The second electrical connection layer 55 may further include a fourth portion 554. The fourth portion 554 of the second electrical connection layer 55 may be fixedly connected between the first portion 551 of the second electrical connection layer 55 and the third portion 553 of the second electrical connection layer 55. A third hollow gap 571 is defined between the fourth portion 544 of the first electrical connection layer 54 and the fourth portion 554 of the second electrical connection layer 55.

[0251] It can be understood that, compared with the solution of fixed connection between the first deformation segment 52 and the second deformation segment 57, the present application hollows out the space between the second deformation segment 57 and the first deformation segment 52, that is, the electrical connector 5 is further layered and hollowed out in the Z-axis direction (width direction), which can further reduce the K value of the electrical connector 5.

[0252] In some embodiments, the same contents as in the previous embodiments are not repeated. Figure 26 yes Figure 4 is a schematic structural diagram of another embodiment of the electrical connector 5. In this embodiment, for ease of description, the direction from the second end 53 of the electrical connector 5 to the first end 51 of the electrical connector 5 is defined as the X-axis, the thickness direction of the electrical connector 5 is defined as the Y-axis, and the Z-axis is perpendicular to the X-axis and Y-axis directions.

[0253] It is understandable that the plurality of electrical connection layers 520 included in the first deformation section 52 of the electrical connection member 5 can be all layered and hollowed out in the length direction, such as Figure 7a and Figure 9 Alternatively, the first deformable segment 52 includes multiple electrical connection layers 520, which can be layered and hollowed out in some positions along the length direction of the electrical connector 5, and not layered in some positions, such as Figure 26 That is, in the length direction of the electrical connector 5, the first deformable section 52 is at a local position, and adjacent electrical connection layers 520 can be overlapped and fixed together, thereby avoiding the loose structure caused by the layered portion being too long.

[0254] In some embodiments, along the length of the electrical connector 5, the first deformable section 52 includes a first portion 5203 and a second portion 5204. The first portion 5203 is fixedly connected to the second portion 5204. Adhesive layers 5205 are provided between adjacent electrical connection layers 520 in the first portion 5203 to ensure a fixed connection between the two adjacent electrical connection layers 520. A hollow portion is provided between adjacent electrical connection layers 520 in the second portion 5204. Figure 26 In the figure, the glue layer 5205 and the electrical connection layer 520 are schematically distinguished by dotted lines.

[0255] It is understood that during the movement of the carrier 2, the first deformable section 52 locally provides an adhesive layer 5205 between two adjacent electrical connection layers 520, thereby firmly connecting the two adjacent electrical connection layers 520 to form the first portion 5203. This effectively prevents the structure from becoming loose due to excessively long delaminated sections. The provision of the first portion 5203 is particularly necessary during long-stroke movement of the carrier 2 relative to the base 1.

[0256] In other embodiments, the multiple electrical connection layers 520 of the first portion 5203 may also be fixedly connected by other means besides gluing. It is understood that the number of first portions 5203 may be one or more. When there are multiple first portions 5203, the multiple first portions 5203 may be spaced apart along the length direction of the electrical connector 5.

[0257] For example, Figure 26 As shown, the first portion 5203 can be a bent section 5201. It is understood that the first deformable section 52 of the electrical connector 5 can include multiple bent sections 5201. Part of the multiple bent sections 5201 can be the first portion 5203, and another part can be the second portion 5204. In other words, some or all of the multiple bent sections 5201 can be selected as needed, so that two adjacent electrical connection layers 520 can be fixedly connected via the adhesive layer.

[0258] It is understandable that during the movement of the carrier 2 , the bending section 5201 deforms more than other sections, and local fixation in the bending section 5201 is more conducive to reducing the risk of structural looseness of the first deformation section 52 .

[0259] In other embodiments, the first portion 5203 may also be a straight line segment.

[0260] The previous text introduced the long-stroke power supply of the electrical connector 5 for the focus voice coil motor 10 of the camera module 100 through the accompanying drawings. The following text will introduce several embodiments of the motor 10 used in different scenarios of the camera module 100 through the accompanying drawings.

[0261] In some embodiments, the same contents as in the previous embodiments are not repeated. Figure 27 It is a structural diagram of another embodiment of the motor 10 provided in the embodiment of the present application. Figure 28 yes Figure 27 An exploded schematic diagram of an embodiment of the motor 10 is shown in FIG. Figure 29 yes Figure 27 FIG. 1 is a schematic structural diagram of the motor 10 at another angle. Figure 30 yes Figure 28Schematic diagram of the structure of an embodiment of the electrical connector 5 shown in FIG. For ease of description, in this embodiment, the thickness direction of the motor 10 is defined as the X-axis. The length direction of the motor 10 is defined as the Y-axis. The width direction of the motor 10 is defined as the Z-axis.

[0262] like Figures 27 to 30 As shown, the motor 10 may include a base 1 , a carrier 2 , a first guide rod 61 , a second guide rod 62 , a coil 3 , a magnet unit 4 and an electrical connector 5 .

[0263] Exemplarily, the first guide rod 61 and the second guide rod 62 can be fixedly connected to the base 1. The length direction of the first guide rod 61 and the length direction of the second guide rod 62 can be parallel to the second direction. The carrier 2 can be slidably connected to the first guide rod 61 and the second guide rod 62. The coil 3 can be fixedly connected to the carrier 2, and the magnet unit 4 can be fixedly connected to the base 1. The coil 3 can face the magnet unit 4. When the coil 3 is energized, the carrier 2 can be driven to move relative to the base 1 under the magnetic field of the magnet unit 4. Exemplarily, the carrier 2 can move relative to the base 1 along the X-axis direction.

[0264] For example, along the length of the electrical connector 5, the electrical connector 5 may include a first end 51, a second end 53, and a first deformable section 52. The first end 51 may be fixedly connected to the base 1, and the second end 53 may be fixedly connected to the carrier 2. The electrical connector 5 may be used to supply power to the coil 3 on the carrier 2. For example, the first end 51 of the electrical connector 5 may be electrically connected to a battery of the electronic device 1000, and the second end 53 may be electrically connected to the coil 3.

[0265] For example, when the carrier 2 can move relative to the base 1 along the second direction, the first end 51 of the electrical connector 5 can move closer to or farther away from the second end 53 of the electrical connector 5 along the second direction.

[0266] It is understood that when the camera module 100 including the motor 10 is installed on the electronic device 1000, the thickness direction of the motor 10 can be parallel to the thickness direction of the electronic device 1000. The motor 10 of the present application can be used in an upright camera module 100. The carrier 2 can be used to carry the lens group. When the carrier 2 moves relative to the base 1, the carrier 2 drives the lens group to move relative to the base 1. The motor 10 can be an autofocus (AF) motor 10 of the upright camera module 100.

[0267] In some embodiments, the first deformable segment 52 may include multiple electrical connection layers 520 , which are spaced apart along a first direction. A hollow portion is formed between adjacent electrical connection layers 520 in the first deformable segment 52 . The first direction and the second direction form an angle.

[0268] In some embodiments, the first deformable section 52 may be a multi-fold structure, that is, the first deformable section 52 of the electrical connector 5 may include a plurality of bending sections 5201 .

[0269] In some embodiments, the same contents as in the previous embodiments are not repeated. Figure 31 It is a structural schematic diagram of another embodiment of the motor 10 provided in an embodiment of the present application. Figure 32 yes Figure 31 An exploded schematic diagram of an embodiment of the motor 10 is shown in FIG. Figure 33 yes Figure 31 The structure of the motor 10 shown in FIG is shown at another angle. For ease of description, in this embodiment, the thickness direction of the motor 10 is defined as the X-axis. The direction of movement of the carrier 2 of the motor 10 is defined as the Z-axis. The Y-axis is perpendicular to the X-axis and perpendicular to the Z-axis.

[0270] like Figures 31 to 33 As shown, the motor 10 may include a base 1 , a carrier 2 , a first guide rod 61 , a second guide rod 62 , a coil 3 , a magnet unit 4 and an electrical connector 5 .

[0271] Exemplarily, the first guide rod 61 and the second guide rod 62 are fixedly connected to the base 1. The length direction of the first guide rod 61 and the length direction of the second guide rod 62 can be parallel to the second direction. The carrier 2 is slidably connected to the first guide rod 61 and the second guide rod 62. The coil 3 can be fixedly connected to the carrier 2, and the magnet unit 4 is fixedly connected to the base 1. The coil 3 faces the magnet unit 4. When the coil 3 is energized, the carrier 2 can be driven to move relative to the base 1 under the magnetic field of the magnet unit 4. Exemplarily, the carrier 2 can move relative to the base 1 along the Z-axis direction.

[0272] In some embodiments, the travel of the carrier 2 of the motor 10 relative to the base 1 may be greater than or equal to 3 mm. For example, the travel of the carrier 2 of the motor 10 relative to the base 1 may be 3 mm, 5 mm, 9 mm, 10 mm, etc.

[0273] In some embodiments, along the length of the electrical connector 5, the electrical connector 5 may include a first end 51, a second end 53, and a first deformable section 52. The first deformable section 52 is fixedly connected between the first end 51 and the second end 53. The first deformable section 52 is electrically connected between the first end 51 and the second end 53. The first end 51 is fixedly connected to the base. The second end 53 is fixedly connected to the carrier 2.

[0274] In some embodiments, the first deformable segment 52 may include multiple electrical connection layers 520 , which are spaced apart along a first direction. A hollow portion is formed between adjacent electrical connection layers 520 in the first deformable segment 52 . The first direction and the second direction form an angle.

[0275] Exemplarily, the electrical connector 5 can be used to supply power to the coil 3. For example, the first end 51 of the electrical connector 5 can be electrically connected to a battery of the electronic device 1000, and the second end 53 can be electrically connected to the coil 3.

[0276] For example, when the carrier 2 can move relative to the base 1 along the Z-axis direction, the first end 51 of the electrical connector 5 can move closer to or farther away from the second end 53 of the electrical connector 5 along the Z-axis direction.

[0277] It is understood that when the camera module 100 including the motor 10 is mounted on the electronic device 1000, the X-axis can be parallel to the thickness direction of the electronic device 1000. The motor 10 of the present application can be used in a periscope camera module 100. The carrier 2 can be used to support the lens assembly. When the carrier 2 moves relative to the base 1, the carrier 2 drives the lens assembly to move relative to the base 1. The motor 10 can be an autofocus (AF) motor 10 of the periscope camera module 100.

[0278] In some embodiments, the electrical connector 5 may include a multi-fold structure, that is, the electrical connector 5 may include a plurality of bending sections 5201 .

[0279] In some embodiments, the same contents as in the previous embodiments are not repeated. Figure 34 It is a partial structural diagram of another implementation manner of the camera module 100 provided in an embodiment of the present application. Figure 35 yes Figure 34 An exploded schematic diagram of an embodiment of the structure shown in FIG. Figure 36 yes Figure 34 A partial cross-sectional view of an embodiment of the structure shown in FIG. 1 at section line FF. Figure 37 yes Figure 35 Schematic diagram of the assembly of one embodiment of the partial structure shown in FIG. Figure 38 yes Figure 35 FIG. 1 is a schematic structural diagram of an embodiment of an electrical connector 5 shown in FIG.

[0280] For ease of description, in this embodiment, the thickness direction of the motor 10 is defined as the X-axis, the length direction of the motor 10 is defined as the Y-axis, and the width direction of the motor 10 is defined as the Z-axis.

[0281] like Figures 34 to 38 As shown, the motor 10 can be used as an image sensor displacement anti-shake motor 10 of the camera module 100. That is, the motor 10 can be used to drive the photosensitive element 302 to move to achieve anti-shake of the camera module 100.

[0282] In some embodiments, the motor 10 may include a base 1, a carrier 2, a coil 3, a magnet unit 4, and an electrical connector 5. The coil 3 may be fixedly connected to the carrier 2, and the magnet unit 4 may be fixedly connected to the base 1. The coil 3 faces the magnet unit 4. When energized, the coil 3 can drive the carrier 2 to move relative to the base 1 under the magnetic field of the magnet unit 4.

[0283] For example, the photosensitive component 30 of the camera module 100 can be installed on the carrier 2. When the coil 3 is energized, the coil 3 can drive the carrier 2 to move relative to the base 1, and then the photosensitive component 30 can move relative to the base 1.

[0284] In some embodiments, the base 1 may include a cover 101 and a frame 102. The cover 101 and the frame 102 are fixedly connected and enclose a movement space 18. The carrier 2, the coil 3, the magnet unit 4, the electrical connector 5, and the photosensitive component 30 may be located within the movement space 18. The magnet unit 4 may be fixed to the cover 101.

[0285] In some embodiments, the travel of the carrier 2 of the motor 10 relative to the base 1 may be greater than or equal to 1 mm. For example, the travel of the carrier 2 of the motor 10 relative to the base 1 may be 1 mm, 2 mm, 3 mm, 5 mm, 9 mm, 10 mm, etc.

[0286] For example, there can be multiple coils 3, each of which is arranged around the optical axis (which can be parallel to the X-axis) and around the photosensitive component 30. The number of magnetic units 4 can match the number of coils 3. When the coils 3 are energized, the magnetic field of the magnetic units 4 can drive the carrier 2 to move in any direction in the YZ plane.

[0287] In some embodiments, along the length of the electrical connector 5, the electrical connector 5 may include a first end 51, a second end 53, and a first deformable section 52. The first deformable section 52 is fixedly connected to the first end 51 and the second end 53. The first deformable section 52 is electrically connected between the first end 51 and the second end 53. The first end 51 is fixedly connected to the base 1, and the second end 53 is fixedly connected to the carrier 2. The electrical connector 5 can be used to supply power to the coil 3. For example, the first end 51 of the electrical connector 5 can be electrically connected to a battery of the electronic device 1000, and the second end 53 can be electrically connected to the coil 3.

[0288] In some embodiments, there may be multiple electrical connectors 5 , and the second ends 53 of the multiple electrical connectors 5 are connected to the periphery of the carrier 2 .

[0289] Illustratively, the first deformable segment 52 may include multiple electrical connection layers 520, which are spaced apart along the first direction. Among the multiple electrical connection layers 520 included in the first deformable segment 52, a hollow space is formed between any two adjacent electrical connection layers 520. Illustratively, the first deformable segment 52 may include three electrical connection layers 520. A first hollow space 521 is defined between the first electrical connection layer 542 and the second electrical connection layer 552, and a second hollow space 522 is defined between the second electrical connection layer 552 and the third electrical connection layer 562.

[0290] In some embodiments, the electrical connector 5 may have a three-dimensional structure. For example, the electrical connector 5 may have a 3D spiral shape. For example, the first deformable section 52 of the electrical connector 5 may include multiple bent sections 5201. These bent sections 5201 may be arranged along the length of the electrical connector 5, and the bent sections 5201 may not lie in the same plane. It is understood that when the electrical connector 5 has a three-dimensional structure, the first direction of the first deformable section 52 may be different at different locations within the electrical connector 5.

[0291] It is understood that, compared to a solution in which the electrical connector 5 is not layered, dividing the electrical connector 5 into multiple, spaced-apart electrical connection layers can significantly reduce the K value of the electrical connector 5. A smaller K value of the electrical connector 5 means that the electrical connector 5 presents less obstruction to the movement of the carrier 2, the driving force required by the coil 3 to drive the carrier 2 can be smaller, the volume of the magnetic coil 3 can be smaller, and the motor 10 structure is more compact.

[0292] It can be understood that the above text realizes the relative movement of the carrier 2 and the base 1 by cooperating with the coil 3 and the magnet unit 4. In other embodiments, the motor 10 can also realize the relative movement of the carrier 2 and the base 1 in other ways, such as gears and motors.

[0293] It is understandable that the relative motion between the carrier 2 and the base 1 is guided by the first guide rod 61 and the second guide rod 62. In other embodiments, the motor 10 may also adopt other types of guide structures, such as slide grooves and ball fits.

[0294] It is understandable that the fixed positions of the coil 3 and the magnet unit 4 can be interchanged, that is, the coil 3 can be fixedly connected to the base 1, and the magnet unit 4 can be fixedly connected to the carrier 2. The electrical connector 5 of the present application can be used for electrical signal transmission of other electronic devices (e.g., sensors, resistors, capacitors, photosensitive elements 302, etc.) on the carrier 2, and is not limited to the coil 3.

[0295] This application describes several electrical connectors 5. Along the length of the electrical connector 5, the electrical connector 5 includes a first end 51, a second end 53, and a first deformable segment 52. The first deformable segment 52 is fixedly connected between the first end 51 and the second end 53. In the first direction, the first deformable segment 52 includes multiple electrical connection layers 520, which are fixedly connected between the first end 51 and the second end 53. The multiple electrical connection layers 520 are arranged at intervals, and at least part of the first deformable segment 52 has a hollow space between adjacent electrical connection layers 520. The first direction is different from the length direction of the electrical connector 5.

[0296] It is understood that the electrical connector 5 can be used to transmit electrical signals to the electronic devices on the carrier 2. The first end 51 is fixedly connected to the base 1 of the motor 10, and the second end 53 is fixedly connected to the carrier 2 of the motor 10. When the carrier 2 of the motor 10 moves relative to the base 1 of the motor 10, the first end 51 moves closer to or farther from the second end 53 in a first direction. For example, the motor 10 includes the carrier 2, the base 1, the electrical connector 5, the coil 3, and the magnet unit 4. The coil 3 is fixedly connected to the carrier 2, and the magnet unit 4 is fixedly connected to the base 1. The coil 3 faces the magnet unit 4 and is used to drive the carrier 2 to move relative to the base 1. The first end 51 can move closer to or farther from the second end 53 in the first direction. The electrical connector 5 can be used to supply power to the coil 3.

[0297] It is understandable that, compared to a solution in which the multiple electrical connection layers of the first deformable segment 52 are fixedly connected by filling glue, the K value of the electrical connector 5 can be reduced by hollowing out the multiple electrical connection layers 520 included in the first deformable segment 52 of the electrical connector 5. During the operation of the motor 10, the carrier 2 moves relative to the base 1, the first deformable segment 52 deforms, and the second end 53 of the electrical connector 5 can move closer to or farther away from the first end 51 of the electrical connector 5 in the first direction. The K value of the electrical connector 5 is small, and the degree of obstruction of the electrical connector 5 to the movement of the carrier 2 is small. The driving force required by the drive unit to drive the carrier 2 to move can be smaller. When the drive unit adopts a combination of magnets and coils, the volume of the magnets and coils 3 can be smaller, and the structure of the motor 10 is more compact. When the motor 10 is used in the camera module 100, it is beneficial to reduce the power consumption of the camera module 100 and help the electronic device 1000 have a longer battery life; when the driving unit adopts a combination of magnets and coils, the volume of the magnets and coils 3 can be smaller, and the structure of the motor 10 is more compact, which is beneficial to the miniaturization of the camera module 100 and the miniaturization of the electronic device 1000.

[0298] It can be understood that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other, and any combination of features in different embodiments is also within the scope of protection of the present application.
