Abstract
Description
[0001] This application claims priority to Chinese Patent Application No. 202111278481.9, filed on October 30, 2021, entitled "Optical Image Stabilization Device, Camera Module and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of photography technology, and in particular to an optical image stabilization device, a camera module, and an electronic device. Background Technology
[0003] When electronic devices with camera functions (such as mobile phones and tablets) take photos, slight shaking often results in blurry, ghosted, or indistinct images. For example, when a person holds an object, there is a certain degree of physiological shaking. During video recording, the person is often in motion. These irregular, involuntary shaking or vibrations cause blurry images and a poor user experience. Therefore, electronic devices with camera functions need to have automatic focus (AF) and optical image stabilization (OIS) functions.
[0004] With the trend towards thinner, lighter, and more multifunctional electronic devices, the design of camera modules presents a challenge: how to design smaller optical image stabilization devices to achieve miniaturization of camera modules, while ensuring that optical image stabilization can efficiently and accurately compensate for and correct the shake of electronic devices. This remains a topic of ongoing exploration in the industry. Summary of the Invention
[0005] This application provides an optical image stabilization device, a camera module, and an electronic device. The optical image stabilization device can efficiently and accurately compensate and correct the shaking of the electronic device, while also having a smaller size to meet the miniaturization design requirements of the camera module.
[0006] In a first aspect, embodiments of this application provide an optical image stabilization device, comprising: an image sensor, a driving assembly, a first connector, and a second connector. The driving assembly includes a fixed member and a movable member capable of relative movement. The movable member is fixedly connected to the image sensor, and the fixed member and the movable member cooperate to drive the image sensor to move along a first direction and a second direction, the first direction and the second direction being arranged at an angle. The first connector includes a first connecting portion, a second connecting portion, and a first elastic portion. The first elastic portion is connected between the first connecting portion and the second connecting portion and is used to realize relative movement between the first connecting portion and the second connecting portion along the first direction. The first connecting portion is fixedly connected to the movable member. The second connector is stacked on top of the first connector and includes a third connecting portion, a fourth connecting portion, and a second elastic portion. The second elastic portion is connected between the third connecting portion and the fourth connecting portion and is used to realize relative movement between the third connecting portion and the fourth connecting portion along the second direction. The third connecting portion is fixedly connected to the fixed member, and the fourth connecting portion is fixedly connected to the second connecting portion.
[0007] By providing a first elastic portion in the first connector, the first and second connectors can move relative to each other in the first direction. By providing a second elastic portion in the second connector, the third and fourth connectors can move relative to each other in the second direction. In this embodiment, the first and second connectors, which are stacked together, are connected between the fixed and movable parts of the drive assembly to realize a force transmission mechanism that drives the image sensor to move in the first and second directions. Since the first and second connectors are stacked, the first elastic portion of the first connector is responsible for the elastic deformation during the movement in the first direction, and the second elastic portion of the second connector is responsible for the elastic deformation during the movement in the second direction. This application can achieve a relatively long lever arm for both the first and second connectors in the first and second directions within a limited space. The force of the drive assembly can achieve a large torque through the first and second connectors, thereby realizing efficient and accurate position compensation and correction of the image sensor.
[0008] If the first and second elastic parts are placed on the same plate-like structure (or the same plane), their lengths will inevitably be limited. To make them sufficiently long, the plate-like structure would need a sufficiently large area, resulting in a very large optical image stabilization device and camera module, hindering miniaturization. It is understood that the first and second connectors provided in this application are both flat plate structures. Since the first and second connectors are stacked, when their dimensions (referring to the area of the flat plate connectors) are fixed, the first and second elastic parts are placed on two different stacked planes (or plates). By maximizing the design space for the dimensions of the first elastic part in the second direction and the second elastic part in the first direction, a longer lever arm and greater output torque can be achieved. This facilitates moving the image sensor to the desired position for efficient and accurate compensation and correction of electronic device shake. Simultaneously, when the required output torque is fixed, this structure allows for a smaller optical image stabilization device, thus meeting the miniaturization design requirements of the camera module.
[0009] In one possible implementation, the connection between the first connecting part and the second connecting part in the second direction is rigid. That is, when the driving component drives the image sensor to move along the second direction, the first connecting part and the second connecting part move synchronously, with no relative movement between them. This can be understood as the elastic deformation of the first elastic part being limited to the first direction; in the second direction, the first elastic part does not have the ability to elastically deform. This solution helps prevent crosstalk between the movement of the image sensor in the first and second directions, thus improving the accuracy of the image sensor's movement.
[0010] In one possible implementation, the third and fourth connecting parts are rigidly connected in the first direction. That is, when the driving component moves the image sensor along the first direction, the third and fourth connecting parts move synchronously, with no relative movement between them. This can be understood as the elastic deformation of the second elastic part occurring only in the second direction; in the first direction, the second elastic part does not have the ability to elastically deform. This solution helps prevent crosstalk between the movement of the image sensor in the first and second directions, thus improving the accuracy of the image sensor's movement.
[0011] In one possible implementation, the moving plane formed by the first and second directions is parallel to the photosensitive surface of the image sensor (or, in other words, parallel to the imaging surface of the image sensor), or the plane containing the first and second connectors is parallel to the photosensitive surface (or imaging surface) of the image sensor. This solution helps prevent crosstalk problems caused by movement in other directions during the movement of the image sensor in the first and second directions. If the moving plane formed by the first and second directions is tilted relative to the photosensitive surface of the image sensor, it will cause the image sensor to rotate or wobble. Therefore, this solution can improve the accuracy of the image sensor's movement.
[0012] In one possible implementation, the first connecting portion is located around the second connecting portion, and the third connecting portion is located around the fourth connecting portion. This can be understood as the second connecting portion being located in the middle region of the first connecting member, and the fourth connecting portion being located in the middle region of the second connecting member. In this embodiment, the middle regions of the first and second connecting members are fixedly connected, the edge of the first connecting member (the first connecting portion) is fixedly connected to the movable member, and the edge of the second connecting member (the third connecting portion) is fixedly connected to the fixed member. That is, the connection points between the first and second connecting members and the drive assembly are located at the outer edges, and the size of the outer edges is larger than that of the middle region, thus improving the reliability of the fixed connection. Specifically, the first and second connecting portions are arranged in the same layer, as are the third and fourth connecting portions. This allows for relative movement of the first and second connecting portions along the first direction and relative movement of the third and fourth connecting portions along the second direction, while also reducing the dimensions of the first and second connecting members perpendicular to the first and second directions, thereby reducing the size of the optical image stabilization device.
[0013] In one possible implementation, the second connecting portion is located around the periphery of the first connecting portion, and the fourth connecting portion is located around the periphery of the third connecting portion. In this solution, the first connecting portion is located in the middle region of the first connecting member, and the third connecting portion is located in the middle region of the second connecting member. The peripheral regions (or edge positions) of the first and second connecting members are fixedly connected. The middle region of the first connecting member is fixedly connected to the movable member, and the middle region of the second connecting member is fixedly connected to the fixed member. This solution provides a fixed connection method that can also achieve the fixed connection of the first and second connecting members between the movable member and the fixed member.
[0014] In one possible implementation, the first elastic part includes at least one first spring wire. The first spring wire includes a first end connected to the first connecting part, a second end connected to the second connecting part, and a first body connected between the first end and the second end. The first body is spaced apart from both the first connecting part and the second connecting part by a gap. The distance the first body extends in the second direction is greater than or equal to the distance the image sensor extends in the second direction. By setting the first elastic part as a spring wire, relative movement between the first connecting part and the second connecting part can be achieved through the elastic deformation of the spring wire. By spacing the first spring wire from the first connecting part and the second connecting part, frictional resistance and frictional damage caused by contact during relative movement of the first connecting part and the second connecting part can be avoided. At the same time, electrical signals can be transmitted sequentially through the first connecting part and the first elastic part to the second connecting part, avoiding short circuits during electrical signal transmission. By making the distance the first body extends in the second direction greater than or equal to the distance the image sensor extends in the second direction, the size of the first body can be maximized when the size of the first connecting part along the second direction is constant. This results in a longer lever arm of the first elastic part in the first direction, leading to a greater elastic force, a greater output torque, and higher driving efficiency.
[0015] In one possible implementation, there are multiple first spring wires, which are arranged sequentially and at intervals between the first connecting portion and the second connecting portion. Increasing the number of spring wires allows for better distribution of electrical traces. If there were only one first spring wire, multiple electrical traces would need to be arranged on the same wire, leading to an increase in the wire's width and consequently a decrease in its elasticity and force. Increasing the number of first spring wires allows for better arrangement of the electrical traces, reduces the wire's width, and increases its deformation capacity, thus ensuring the elastic deformation capability of the first elastic portion. By spacing the multiple first spring wires between the first connecting portion and the second connecting portion, frictional resistance and damage caused by contact during relative movement of the two portions can be avoided. Furthermore, the electrical signal can be transmitted sequentially through the first connecting portion and the first elastic portion to the second connecting portion, preventing short circuits during signal transmission.
[0016] In one possible implementation, the first body includes a first segment and a second segment, the second segment being bent and extended relative to the first segment. The first end is the end of the first segment furthest from the second segment, and the second end is the end of the second segment furthest from the first segment. The first segment extends along a second direction. By dividing the first body into a first segment and a second segment that are bent and connected to each other, with the first segment used for elastic deformation and the second segment used for fixation, it is advantageous to extend the length of the first spring wire in the first direction, thereby enabling the output of a larger torque. If the first body only includes the first segment, the length of the first spring wire in the first direction is shortened, the lever arm is shorter, and the output torque will be correspondingly reduced.
[0017] In one possible implementation, the first body is in the shape of a straight strip and extends along the second direction, with the two ends of the first body connected to the second connecting portion and the first connecting portion, respectively. Setting the first elastic portion in the shape of a straight strip helps to ensure the stability of the direction of the elastic force and to guarantee the direction of the force.
[0018] In one possible implementation, there are two first elastic parts, which are respectively disposed on both sides of the second connecting part in a first direction. By having two first elastic parts, and symmetrically disposed on both sides of the second connecting part, the second connecting member is subjected to more balanced forces, thereby enabling it to move in a straight line. This facilitates control over its movement distance, allowing the image sensor to be precisely adjusted to the desired position.
[0019] In one possible implementation, the outer edge of the second connecting portion includes a first side, a second side, a third side, and a fourth side connected sequentially in a closed frame shape. The first and second sides are arranged opposite to each other, as are the third and fourth sides. The first connecting portion includes a first connecting piece and a second connecting piece. The first connecting piece is located on the periphery of the first side and is spaced apart from the first side by a gap. The second connecting piece is located on the periphery of the third side and is spaced apart from the third side by a gap. One first elastic part is located on the periphery of the third side and connects the second connecting piece and the second connecting portion, and the other first elastic part is located on the periphery of the fourth side and connects the first connecting piece and the second connecting portion. By including the first connecting piece and the second connecting piece in the first connecting portion, and symmetrically arranging the first and second connecting pieces on both sides of the second connecting portion, both sides of the second connecting portion are simultaneously subjected to the forces of the first and second connecting pieces, thereby maintaining a state of force balance during movement. The movement trajectory will not be skewed, which is beneficial for precise adjustment of the image sensor position.
[0020] In one possible implementation, one of the first elastic portions is connected to the second connecting portion at a position on the third side adjacent to the first side, and the other first elastic portion is connected to the second connecting portion at a position on the fourth side adjacent to the second side. By symmetrically arranging the connection positions of the first connecting piece and the second connecting piece with the second connecting portion, the forces between the first connecting piece and the second connecting portion and the forces between the second connecting piece and the second connecting portion are balanced, thereby preventing tilting and offset of the relative movement between the first connecting portion and the second connecting portion, which is beneficial for precise adjustment of the image sensor position.
[0021] In one possible implementation, the region between the first connecting piece and the second connecting piece includes a first region and a second region disposed adjacent to each other along a first direction. A second connecting portion and two first elastic portions are located in the first region, and the second region is used to accommodate an optical component for transmitting incident light to an image sensor. By providing a second region between the first connecting piece and the second connecting piece, both mounting space for the optical component and a channel for light to enter the image sensor are provided.
[0022] In one possible implementation, the optical element is a light-reflecting element used to reflect incident light to the image sensor. By incorporating a light-reflecting element into the optical image stabilization device, the element can alter the optical path of the light, allowing it to enter the image sensor perpendicularly, which helps reduce the size of the camera module. Furthermore, by providing a second region in the first connector that faces the image sensor and housing the light-reflecting element in that second region, the size of the optical image stabilization device can be reduced compared to a structure where the light-reflecting element is located outside the device.
[0023] In one possible implementation, the second connecting portion includes a first connecting body and two first extensions. One first extension is located near the third side of the first side and connected to the first sub-elastic part; the other first extension is located near the fourth side of the second side and connected to the second sub-elastic part. In this solution, by using a first extension instead of a second segment, the first elastic part and the second connecting portion can still be rigidly connected in the first direction, and the length of the first connecting body in the second direction can be maximized to increase the torque of the first connecting member.
[0024] In one possible implementation, the area surrounded by the third connecting portion includes a third region and a fourth region adjacent to each other along the first direction. The fourth connecting portion includes a second connecting body and a second extension. The second connecting body and the second connecting portion are stacked and fixedly connected. The second connecting body is located in the third region, the second extension is located in the fourth region, a portion of the second elastic portion is located in the third region, and a portion of the second elastic portion is located in the fourth region. The fourth region and the second region are arranged opposite to each other in the stacking direction. By providing the fourth region on the second connector, and by symmetrically arranging the fourth region and the second region in the stacking direction, light can enter the image sensor on the side of the second connecting region facing away from the first connector. By providing the extension to connect with the second elastic portion, it is beneficial to extend the length of the second elastic portion in the first direction, thereby enabling the output of a larger torque.
[0025] In one possible implementation, the second elastic part includes at least one second spring wire. The second spring wire includes a third end connected to the third connecting part, a fourth end connected to the fourth connecting part, and a second body connected between the third end and the fourth end. The second body is spaced apart from both the third and fourth connecting parts by gaps. The extension distance of the second body in the first direction is greater than or equal to the extension distance of the image sensor in the first direction. By setting the second elastic part as a spring wire, and by ensuring that the extension distance of the second body in the first direction is greater than or equal to the extension distance of the image sensor in the first direction, the size of the second body can be maximized when the size of the second connector along the first direction is constant. This results in a greater elastic force and a greater output torque in the second elastic part in the second direction.
[0026] In one possible implementation, the second body includes a third segment and a fourth segment. The fourth segment extends beyond the third segment by bending. The third end is the end of the third segment away from the fourth segment, and the fourth end is the end of the fourth segment away from the third segment. The third segment extends along a first direction. There are two second elastic portions. The fourth segment of one second elastic portion is located in the third region and connected to a corner of the connecting body away from the extension. The fourth segment of the other second elastic portion is located in the fourth region and connected to an end of the extension away from the connecting body. By segmenting the second body and bending the third and fourth segments relative to each other, with the fourth segments of the first and second elastic portions located at two diagonal positions of the second connector, the length of the third segment can be extended, thereby extending the lever arm of the second elastic portion and increasing the torque of the second connector in the second direction. Simultaneously, the points of force application between the first and second connectors can be symmetrically positioned, which is beneficial for maintaining balance and stability during the movement of the first and second connectors.
[0027] In one possible implementation, the third connecting portion has an open frame structure and includes a notch. In the first direction, a fourth region is arranged between the notch and the third region. By designing a notch in the third connecting portion and making the notch communicate with the fourth region, the size of the space available for accommodating the optical component in the first direction is expanded within a limited size range. This facilitates the installation of the optical component and is beneficial for the miniaturization design of the optical image stabilization device.
[0028] In one possible implementation, both the first and second connectors are hollow frame structures, enclosing a light-transmitting area. The first connecting portion, the first elastic portion, and the second connecting portion are located around the light-transmitting area, as are the third connecting portion, the second elastic portion, and the fourth connecting portion. The light-transmitting area is used to house the image sensor. By providing a light-transmitting area in the middle region of the first and second connectors to house the image sensor, a channel for light to enter the image sensor is provided, along with mounting space for the image sensor, thus reducing the size of the optical image stabilization device.
[0029] In one possible implementation, both the first and second connectors are hollow frame structures, enclosing a light-transmitting area. The first connecting portion, the first elastic portion, and the second connecting portion are located around the light-transmitting area, as are the third connecting portion, the second elastic portion, and the fourth connecting portion. The light-transmitting area is used to house optical components, which are positioned on the incident light path of the image sensor. By setting a light-transmitting area in the middle region of the first and second connectors to house the optical components, installation space for the optical components in the optical image stabilization device is saved, facilitating the miniaturization design of the optical image stabilization device.
[0030] In one possible implementation, both the first and second connectors are hollow frame structures, enclosing a light-transmitting area. The first connecting portion, the first elastic portion, and the second connecting portion are located around the light-transmitting area, as are the third connecting portion, the second elastic portion, and the fourth connecting portion. The space within the light-transmitting area serves as the optical path between the optical component and the image sensor. By providing a light-transmitting area in the middle region of the first and second connectors, a channel is provided for light to enter the image sensor.
[0031] In one possible implementation, the first connector includes a first electrical trace, which sequentially electrically connects the first connecting portion, the first elastic portion, and the second connecting portion. The second connector includes a second electrical trace, which sequentially electrically connects the fourth connecting portion, the second elastic portion, and the third connecting portion. The first connecting portion is electrically connected to the image sensor, the first electrical trace and the second electrical trace are electrically connected, and the third connecting portion is used for electrical connection to an external circuit board. By providing the first electrical trace on the first connector and the second electrical trace on the second connector, and electrically connecting the first and second electrical traces, and by arranging the first and second electrical traces, the purpose of electrically connecting the image sensor to the external circuit is achieved. The embodiments of this application integrate the structure of the electrical connection between the image sensor and the external circuit onto the first and second connectors, so that the first and second connectors can not only be used as a linkage mechanism between fixed and moving parts, but also have interconnected first and second electrical traces, forming a partial electrical connection path between the image sensor and the external circuit. This combines the functions of both elastic connection and electrical connection in terms of mechanism, which is beneficial for the miniaturization design of the camera module. Furthermore, the first and second connectors are rigid plate structures, and the first and second electrical traces are set on the rigid plate structure, which helps to ensure the stability and lifespan of the transmitted signals of the first and second electrical traces.
[0032] In one possible implementation, the first connector includes a first substrate and a first circuit layer stacked together, with a first electrical trace disposed on the first circuit layer; the second connector includes a second substrate and a second circuit layer stacked together, with a second electrical trace disposed on the second circuit layer, and the first and second substrates are disposed adjacent to each other and fixedly connected. By configuring the first and second connectors as a structure of stacked substrates and circuit layers, the substrates can provide support and fixation, the circuit layers can be used to arrange electrical traces to achieve electrical connection, and by making the first and second substrates adjacent to each other and fixedly connected, the first and second circuit layers can be separated to avoid short circuits.
[0033] In one possible implementation, the first substrate and the second substrate are provided with through holes, which connect the first circuit layer and the second circuit layer. A conductive structure is provided within the through holes to electrically connect the first connector and the second connector. When the first substrate and the second substrate are disposed adjacent to each other and fixedly connected, the first circuit layer and the second circuit layer are separated by the first substrate and the second substrate. By forming through holes on the first substrate and the second substrate and providing conductive structures within the through holes, the first electrical trace and the second electrical trace can be electrically connected.
[0034] In one possible implementation, the first connector includes a first substrate and a first circuit layer stacked together, with a first electrical trace disposed on the first circuit layer; the second connector includes a second substrate and a second circuit layer stacked together, with a second electrical trace disposed on the second circuit layer, and the first and second circuit layers are adjacent to each other and fixedly connected. In this solution, the first and second circuit layers are adjacent to each other and fixedly connected, eliminating the need for drilling holes in the first and second substrates to electrically connect the first and second electrical traces, resulting in a simple structure that is easy to manufacture.
[0035] In one possible implementation, the movable component is equipped with a coil, and the fixed component is equipped with a magnetic structure. The magnetic structure is positioned opposite the coil. When the coil is energized, it cooperates with the magnetic structure to drive the image sensor to move along a first direction or a second direction. In this solution, the magnetic structure provides a magnetic field. When current is passed through the coil, the coil generates a magnetic thrust under the action of the magnetic field, driving the image sensor to move along the first or second direction. By controlling the magnitude and direction of the current in the coil, the direction and distance of the image sensor's movement can be controlled. The driving method is simple and easy to control.
[0036] In one possible implementation, the movable component includes a drive plate and a bending portion. The coil is disposed on the drive plate, and the bending portion is connected to a pair of opposing edges on the drive plate. A first connector is fixedly connected to the edge of the bending portion away from the drive plate. By fixing the first connector to the edge of the bending portion away from the drive plate, the movable component's driving function on the first connector is achieved. At the same time, the bending portion separates the first connector from the drive portion, preventing the first connector from contacting the coil and affecting the coil's movement.
[0037] In one possible implementation, the first connector, the bent portion, and the drive plate together enclose a receiving space, with the fixing member located within the receiving space, and the second connector located on the side of the first connector opposite to the fixing member. This stacking arrangement helps reduce the thickness of the optical image stabilization device while ensuring the driving force provided by the drive assembly, thus improving the efficiency of the drive assembly in moving the image sensor.
[0038] In one possible implementation, the first connector, the bent portion, and the drive plate together enclose a receiving space, the second connector is disposed within the receiving space, and the fixing member is located on the side of the drive plate opposite to the second connector. In this solution, by placing the second connector within the receiving space and the fixing member on the side of the drive plate opposite to the second connector, the structure of the optical image stabilization device can be made more compact, which is beneficial for reducing the overall size of the optical image stabilization device.
[0039] Secondly, this application provides a camera module, including a module bracket, a lens assembly, and an optical image stabilization device as described in any embodiment of the first aspect, wherein both the lens and the optical image stabilization device are mounted within the module bracket. In this solution, by applying the optical image stabilization device of the first aspect embodiment to the camera module, the camera module can still achieve clear imaging under shaking or vibration conditions, while also possessing the characteristic of miniaturization.
[0040] Thirdly, this application provides an electronic device including a processor and a camera module as described in any embodiment of the second aspect. The processor is electrically connected to the camera module and is used to process image signals output by an image sensor. By applying the camera module described in the second aspect to the electronic device, the electronic device has higher quality imaging capabilities and is easier to miniaturize, improving the user experience and thus becoming more competitive.

[0082] Please refer to the following: Figure 3 and Figure 4 , Figure 3 yes Figure 2 The diagram shown illustrates the structure of the camera module 4001 in Embodiment 1. Figure 4 yes Figure 3The diagram shows a cross-section of the camera module 4001 along point AA. The camera module 4001 provided in Embodiment 1 is a periscope camera module. Periscope lens modules can reduce the height requirement of the camera module 4001 by changing the light propagation path, thereby reducing the overall thickness of the electronic device. The camera module 4001 includes a module bracket 10, a light-converting element 20, an optical lens group 30, and an optical image stabilization device 40, wherein the light-converting element 20 and the optical lens group 30 constitute the lens assembly of the camera module 4001.
[0083] The module bracket 10 is used to fix, support, and protect the various components of the camera module 4001, such as the light-converting component 20, the optical lens group 30, and the optical image stabilization device 40. The module bracket 10 includes a top wall 101, a side wall 102, and a bottom wall 103. The bottom wall 103 is disposed opposite to the top wall 101. The top wall 101, side wall 102, and bottom wall 103 can be integrally formed or fixed into an integral structure by assembly (e.g., welding or bonding). The top wall 101, side wall 102, and bottom wall 103 enclose a receiving space G1, within which the light-converting component 20, the optical lens group 30, and the optical image stabilization device 40 are all housed. The top wall 101 is provided with a light-transmitting hole 111, which connects the housing space G1 and the outside of the module bracket 10. When the camera module 4001 is installed in the electronic device, the light-transmitting hole 111 can be directly facing the light-entry hole on the outer shell of the electronic device, and external light can enter the housing space G1 through the light-transmitting hole 111.
[0084] The light-reversing element 20 is used to change the direction of the incident light. It works by using a total internal reflection prism to refract the incident light at a 90-degree angle perpendicular to the optical axis before it enters the optical imaging device. For example... Figure 4 As shown, the light-converting element 20 includes an incident light surface 21, a reflective surface 22, and an exiting light surface 23. The incident light surface 21 is positioned directly opposite the light-transmitting aperture 111. External light passes through the light-transmitting aperture 111 and enters the incident light surface 21 perpendicularly. After being reflected by the reflective surface 22, the light is deflected by 90 degrees and finally exits parallel to the exiting light surface 23 in a direction perpendicular to it. For example, the light-converting element 20 is a total internal reflection prism, which can be a triangular prism, a quadrangular prism, or a reflector, etc.
[0085] The optical lens group 30 and the light-converting element 20 together constitute the lens group of the camera module 4001. The optical lens group 30 consists of at least one optical lens and includes an object side and an image side. The object side is disposed opposite to the light-emitting surface 23, and the image side is disposed opposite to the optical image stabilization device 40. The object side receives light reflected by the light-converting element 20, which is then converged or diverged by the optical lens before entering the optical image stabilization device 40 from the image side. For example, the optical lens group 30 can contain multiple optical lenses, and the optical axes 301 of the multiple optical lenses coincide, thereby giving the optical lens group 30 better optical performance. The optical lens group 30 may include at least one convex lens and at least one concave lens. In this embodiment, to describe the operating direction of the optical image stabilization device 40, a first direction X, a second direction Y, and a third direction Z are determined with the camera module 4001 as a reference. The first direction X and the second direction Y are set at an angle, and the third direction Z is perpendicular to the first direction X and the second direction Y. In this configuration, the optical axis 301 of the optical lens group 30 is perpendicular to the third direction Z of the camera module 4001. This perpendicularity means that the optical lens group 30 and the optical image stabilization device 40 can be arranged side-by-side along either the first direction X or the second direction Y, thereby reducing the size of the camera module 4001 in the third direction Z. The optical axis 301 of the optical lens group 30 refers to the line connecting the center of the optical lens group 30. In some embodiments, the optical lens group 30 may also include a freeform surface lens. In other embodiments, the optical lens group 30 may include only one lens to simplify the structure of the camera module 4001. In this case, the lens can be a convex lens to converge light.
[0086] The optical image stabilization device 40 is provided with a light-transmitting part 401, which is disposed opposite to the image side of the optical lens group 30. The light-transmitting part 401 can be a structure made of a light-transmitting material, such as a transparent glass plate or a transparent plastic plate. Alternatively, the light-transmitting part 401 can also be a light-transmitting hole opened on the optical image stabilization device 40 to receive light adjusted by the optical lens group 30. The optical image stabilization device 40 is fixed in the receiving space, for example, it can be fixed to the inner surface of the receiving space G1 by adhesive bonding. The inner surface of the receiving space G1 can be either the bottom wall 103 or the side wall 102 to ensure high structural stability of the camera module 4001. In some other embodiments, the optical image stabilization device 40 can also be fixed in the receiving space G1 by snap-fitting, welding or other methods. When the camera module 4001 shakes, the optical image stabilization device 40 can move in coordination with its internal components to compensate for the shake of the camera module 4001, thereby improving image clarity.
[0087] In some embodiments, please refer to Figure 4The optical image stabilization device 40 also includes an image sensor 1 and an external circuit board 2. The image sensor 1 (also called a photosensitive element) is a semiconductor chip with hundreds of thousands to millions of photodiodes on its surface, which generate electrical charges when exposed to light. The image sensor 1 can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) device. The image sensor 1 is used for photoelectric conversion and A / D (analog / digital) conversion of the incident light signal. The image sensor 1 is electrically connected to the external circuit board 2. A through-hole 112 is also provided on the module bracket 10. In this embodiment, the through-hole 112 is located at the connection between the side wall 102 and the bottom wall 103. The external circuit board 2 is partially housed within the receiving space G1 and partially extends through the through-hole 112 to the outside of the camera module 4001 to connect with external circuitry. External light enters the light-transmitting hole 111 of the camera module 4001 through the light-entry hole on the electronic device housing, and then enters the light-reflecting component 20 through the light-transmitting hole 111. The light-reflecting component 20 reflects and redirects the light, which then enters the optical image stabilization device 40 perpendicularly in a direction parallel to the optical axis 301. The light then passes through the light-transmitting part 401 and reaches the image sensor 1. In this embodiment, the light from the image sensor 1 is converted into an electrical signal and transmitted to the external circuit board 2. The external circuit board 2 extends out of the camera module 4001 through the through hole 112 and is electrically connected to the external circuit, transmitting the electrical signal to the external circuit, ultimately realizing the optical imaging of the camera module 4001 and the signal transmission between the internal and external circuits.
[0088] In some embodiments, please refer to the following: Figures 5 to 7 , Figure 5 for Figure 3 The schematic diagram shown is an overall structural diagram of the optical image stabilization device 40 in Embodiment 1. Figure 6 for Figure 5 The exploded view of the optical image stabilization device 40 shown is a schematic diagram. Figure 7 for Figure 5 The diagram shows a cross-section of the optical image stabilization device 40 at point BB. The optical image stabilization device 40 includes a light steering component 3, a housing 4, a drive assembly M, a first connector 7, and a second connector 8. The drive assembly M includes a movable component 5 and a fixed component 6. The movable component 5 is fixedly connected to the image sensor 1. The movable component 5 and the image sensor 1 can be directly fixed, or fixed by placing other structures (such as a circuit board) between the movable component 5 and the image sensor 1. The movable component 5 and the fixed component 6 cooperate to drive the image sensor 1 to move along a first direction X and a second direction Y.
[0089] The outer casing 4 includes a base plate 41, a middle frame 42, and a top cover 43. The base plate 41 and the middle frame 42 enclose a receiving cavity G2, within which the light-directing component 3 is disposed. The outer casing 4 covers the side of the middle frame 42 facing away from the base plate 41, providing support and protection for the light-directing component 3. The top cover 43 can be any structural component made of metal, plastic, ceramic, etc. The base plate 41, the middle frame 42, and the top cover 43 can be either a separate structure connected by snap-fit, welding, or fasteners, or a one-piece molded structure.
[0090] The light-directing component 3 is fixed inside the receiving cavity G2, and along the optical path direction, the light-directing component 3 is disposed on the optical lens group 30 (e.g., Figure 4 The light deflector 3 is located between the optical lens group 30 (as shown) and the image sensor 1. The light deflector 3 includes an incident surface 31, a reflecting surface 32, and an exiting surface 33. The incident surface 31 is disposed on the image side of the optical lens group 30, and the exiting surface 33 is disposed opposite to the image sensor 1. The light emitted from the optical lens group 30 enters the light deflector 3 through the incident surface 31, and is then reflected by the reflecting surface 32, causing the light to be deflected by 90 degrees. Finally, the light is emitted from the exiting surface 33 and reaches the image sensor 1.
[0091] In Embodiment 1, the driving component M is a voice coil motor. The movable part 5 is provided with a coil, and the fixed part 6 is provided with a magnetic structure, such as a magnet. Exemplarily, the magnetic structure can also be provided on the movable part 5 and the coil is provided on the fixed part 6. It is only necessary to ensure that when the coil is energized, the movable part 5 and the fixed part 6 can generate relative displacement along the first direction X or the second direction Y through the cooperation of the coil and the magnetic structure.
[0092] The first connecting member 7 and the second connecting member 8 are stacked and fixedly connected. The first connecting member 7 is directly fixedly connected to the movable member 5 or fixed through other connecting structures. The second connecting member 8 is relatively fixed to the fixed member 6. Its fixing method can be either directly fixed to the fixed member 6 or relatively fixed to the fixed member 6 by connecting with other fixing structures (such as the middle frame 42). The first connecting member 7 and the second connecting member 8 constitute an elastic connection structure between the fixed member 6 and the movable member 5, and are also the force transmission mechanism for the drive component M to drive the image sensor 1 to move along the first direction X and the second direction Y.
[0093] The external circuit board 2 can be an FPC (Flexible Printed Circuit), which has bendable characteristics. An opening 01 is provided at the connection between the middle frame 42 and the base plate 41. The external circuit board 2 is bent at the opening 01, with part of it housed within the receiving cavity G2 and part extending from inside the receiving cavity G2 to outside through the opening 01. Furthermore, the opening 01 communicates with the through hole 112 on the module bracket 10, allowing the external circuit board 2 to pass through the receiving cavity G2, the receiving space G1, and finally extend to the outside of the camera module 4001 to electrically connect with the external circuitry. Additionally, the portion of the external circuit board 2 housed within the receiving cavity G2 is also electrically connected to the image sensor 1. This connection can be achieved using conductive metal wires or contact connections. Electrical signals from the image sensor 1 are transmitted to the external circuitry via the external circuit board 2, thereby enabling signal transmission between the optical image stabilization device 40 and the external circuitry. The external circuitry is typically the graphics processor or central processing unit of the electronic device 1000, such as a mobile phone motherboard.
[0094] For example, the external circuit board 2 can also be a PCB (Printed Circuit Board), in which case the optical image stabilization device 40 can be connected to the external circuit through the cooperation of multiple circuit boards. Alternatively, the external circuit board 2 can also be a rigid-flex board, that is, the external circuit board 2 is a structure combining a flexible circuit board and a reinforcing plate, wherein the reinforcing plate is used to provide rigid support, and the flexible circuit board is used to transmit electrical signals. The material of the external circuit board 2 can be reasonably designed according to actual needs.
[0095] In some embodiments, please refer to the following: Figure 6 and Figure 7The optical image stabilization device 40 also includes a first circuit board 63. The first circuit board 63 has corresponding circuitry, enabling the transmission of electrical signals. The image sensor 1 is fixed to the surface of the first circuit board 63 by welding, adhesive bonding, or other methods. Furthermore, the image sensor 1 is electrically connected to the first circuit board 63 via a conductive material. For example, the image sensor 1 and the first circuit board 63 are electrically connected via gold wire. The gold wire reduces the resistance between the image sensor 1 and the first circuit board 63, thereby matching higher power consumption. Moreover, the high chemical stability of the gold wire ensures the reliability of the electrical connection. Additionally, the gold wire has good ductility, making it suitable for processing and reducing processing difficulty. In other embodiments, the image sensor 1 can also be electrically connected to the first circuit board 63 via silver wire, plating, conductive adhesive, or other methods. Alternatively, a conductive material can be used to simultaneously fix and electrically connect the image sensor 1 to the first circuit board 63, such as solder ball bonding. In addition, the first circuit board 63 is electrically connected to the external circuit board 2, thereby transmitting the electrical signal of the image sensor 1 to the external circuit board 2, and communicating with the central processing unit or graphics processor of the electronic device through the external circuit board 2 to complete the functions of acquiring, converting and processing optical images.
[0096] For example, the first circuit board 63 can be a copper clad laminate (CCL), and the reinforcing material of the copper clad laminate can be paper, glass fiber, ceramic, silicon dioxide, boron nitride, metal, resin and composite materials, etc.
[0097] By fixing the image sensor 1 onto the first circuit board 63 and electrically connecting the first circuit board 63 to the image sensor 1, the first circuit board 63 can both support and fix the image sensor 1 and realize the function of transmitting signals from the image sensor 1.
[0098] In some embodiments, please refer to the following: Figure 6 and Figure 8 , Figure 8 for Figure 6The diagram shows the structure of the movable component 5. The movable component 5 is fixedly connected to the first circuit board 63 and drives the first circuit board 63 to move, thereby driving the image sensor 1 fixed on the first circuit board 63 to move. In this embodiment, the movable component 5 is directly fixed to the first circuit board 63. In other embodiments, the movable component 5 and the first circuit board 63 can be kept relatively fixed by setting other connection structures to achieve synchronous movement. Exemplarily, the movable component 5 is part of a voice coil actuator (VCM). The movable component 5 can move relative to the middle frame 42. The movable component 5 is fixedly connected to the image sensor 1 by being fixed to the first circuit board 63, and is used to drive the image sensor 1 to move along the first direction X and the second direction Y. The plane formed by the first direction X and the second direction Y is parallel to the photosensitive surface of the image sensor 1. In this embodiment, "parallel" means approximately parallel; in practical applications, a certain range of error is allowed. This solution helps prevent crosstalk issues caused by movement in other directions during the movement of the image sensor 1 in the first direction X and the second direction Y. If the moving plane formed by the first direction X and the second direction Y is tilted relative to the photosensitive surface of the image sensor 1, the image sensor 1 will rotate or wobble. Therefore, this solution can improve the accuracy of the movement of the image sensor 1.
[0099] The movable component 5 includes a drive plate 51 and a bending portion 52. The drive plate 51 is a conductive second circuit board, comprising a first drive plate 511 and a second drive plate 512. The first drive plate 511 extends along a first direction X, and the second drive plate 512 extends along a second direction Y. A first coil 531 is provided on the first drive plate 511, and the first coil 531 includes a first long side 5310 extending along the first direction X. A second coil 532 is provided on the second drive plate 512, and the second coil 532 includes a second long side 5320 extending along the second direction Y. When the first long side 5310 is subjected to a pushing force along the second direction Y, the first coil 531 drives the movable component 5 to move along the second direction Y; when the second long side 5320 is subjected to a pushing force along the first direction X, the second coil 532 drives the movable component 5 to move along the first direction X.
[0100] In Embodiment 1, there are two first drive plates 511. These two drive plates 511 are parallel to each other and positioned opposite each other on opposite sides of the second drive plate 512 along the second direction Y, ultimately forming a U-shaped structure. It is understood that "parallel" in this embodiment refers to approximately parallel; due to potential errors in actual manufacturing and application, a certain angle is allowed between the two drive plates 511. The first coil 531 and the second coil 532 are mounted on the drive plate 51 by embedding. In other embodiments, the first coil 531 and the second coil 532 can also be fixed to the drive plate 51 by winding, bonding, welding, or adhesive methods.
[0101] like Figure 6 As shown, the bending portion 52 includes a first bending plate 521 and a second bending plate 522. The first bending plate 521 and the second bending plate 522 are respectively fixed on opposite sides of the drive plate 51 in the second direction Y. The bending portion 52 and the drive plate 51 constitute a receiving space.
[0102] In addition, see Figure 6 and Figure 8 The fixing component 6 includes a magnetic structure 61 and a stator 62. The magnetic structure 61 is fixed on the stator 62, and the stator 62 is spaced apart from the drive plate 51. In this embodiment, the stator 62 has corresponding grooves at the positions of the first coil 531 and the second coil 532. The openings of the grooves face the drive plate 51. The magnetic structure 61 is housed in the groove and fixed to the inner wall of the groove by adhesive, thus being embedded in the stator 62. In other embodiments, the magnetic structure 61 can also be fixedly connected to the stator 62 by adhesive, snap-fit, etc. The magnetic structure 61 includes a first magnetic pole and a second magnetic pole. Optionally, the first magnetic pole is the N pole and the second magnetic pole is the S pole. Magnetic field lines are emitted from the N pole and eventually converge to the S pole, thereby forming a magnetic field. When current is passed through the first coil 531 and the second coil 532, this magnetic field is used to cooperate with the first coil 531 and the second coil 532 to generate thrust, thereby pushing the movable component 5 to move.
[0103] In Embodiment 1, the stator 62 is fixed on the base plate 41. The stator 62 is also provided with a receiving groove 641. In one embodiment, the receiving groove 641 is directly opposite to the image sensor 1. In other embodiments, the receiving groove 641 does not necessarily need to be directly opposite the image sensor 1 as long as it is located on the path of the light entering the image sensor 1. Depending on the characteristics of the optical element to be set, the receiving groove 641 and the image sensor 1 can also be offset relative to each other by a preset displacement. The light diverting component 3 is housed in the receiving groove 641 and fixedly connected to the stator 62. While the stator 62 fixes the light diverting component 3 in the optical image stabilization device 40, the receiving groove 641 also helps to reduce the size of the optical image stabilization device 40 in the direction perpendicular to the image sensor 1.
[0104] For example, when current is applied to the first coil 531, the first coil 531 experiences a magnetic thrust along the second direction Y under the magnetic field generated by the magnetic structure 61, causing the movable member 5 to move along the second direction Y. When current is applied to the second coil 532, the second coil 532 generates a magnetic thrust along the first direction X under the magnetic field of the magnetic structure 61, causing the movable member 5 to move along the first direction X. Furthermore, the magnitude of the magnetic thrust generated by the first coil 531 and the second coil 532 differs depending on the magnitude of the applied current. Therefore, the required thrust can be obtained by controlling the magnitude of the current, thereby ensuring that the efficiency and power of the drive component M meet the requirements.
[0105] By using a VCM as the power source for the moving part 5, it can be driven by DC power, eliminating the need for PWM drive. Furthermore, the VCM has a fast feedback speed, meeting the requirements of typical camera scenarios. By rationally designing the direction and magnitude of the current flowing into the coil, the driving efficiency of the optical image stabilization device 40 can be adjusted as needed, allowing the image sensor 1 to be adjusted to the required position, which is beneficial for reverse compensation against external environmental vibrations.
[0106] In some embodiments, please also refer to Figure 6 and Figure 9 , Figure 9 for Figure 6 The schematic diagram of the first connector 7 shown illustrates that the first connector 7 includes a first connecting portion 71, a second connecting portion 72, and a first elastic portion 73. The first connecting portion 71 is disposed around the second connecting portion 72. Both the first connecting portion 71 and the second connecting portion 72 are made of supporting materials such as metal plates, ceramic sheets, or glass plates. The first elastic portion 73 is made of an elastic material, such as a spring or a polymer material, and can undergo elastic deformation under stress. The first elastic portion 73 connects the first connecting portion 71 and the second connecting portion 72 and can elastically deform along a first direction X to achieve relative movement between the first connecting portion 71 and the second connecting portion 72 along the first direction X.
[0107] The outer edge of the second connecting portion 72 includes a first side 721, a second side 722, a third side 723, and a fourth side 724 connected in sequence to form a closed frame. The first side 721 is opposite to the second side 722, and the third side 723 is opposite to the fourth side 724. The first connecting portion 71 includes a first connecting piece 711 and a second connecting piece 712. The first connecting piece 711 is disposed on the periphery of the first side 721 and spaced apart from it by a gap H1; the second connecting piece 712 is disposed on the periphery of the second side 722 and spaced apart from it by a gap H2. By including the first connecting piece 711 and the second connecting piece 712 in the first connecting portion 71, and symmetrically arranging them on both sides of the second connecting portion 72, both sides of the second connecting portion 72 are simultaneously subjected to the forces of the first connecting piece 711 and the second connecting piece 712. This ensures that the force balance is maintained during movement, preventing skewing of the movement trajectory and facilitating precise adjustment of the position of the image sensor 1. Furthermore, by making the first connecting piece 711 and the second connecting piece 712 spaced apart from the second connecting part 72, motion interference and friction damage between the first connecting part 71 and the second connecting part 72 are avoided.
[0108] There are two first elastic portions 73, including a first sub-elastic portion 731 and a second sub-elastic portion 732, which are respectively disposed on both sides of the second connecting portion 72 in the first direction X. The first sub-elastic portion 731 is located on the periphery of the third side 723 and connects the second connecting portion 72 and the second connecting piece 712, with its connection point to the second connecting portion 72 located near the third side 723. The second sub-elastic portion 732 is located on the periphery of the fourth side 724 and connects the first connecting piece 711 and the second connecting portion 72, with its connection point to the second connecting portion 72 located near the fourth side 724. By making the connection positions of the first sub-elastic part 731 and the second sub-elastic part 732 with the second connecting part 72 centrally symmetrical about the second connecting part 72, the force between the first connecting part 71 and the second connecting part 72 is also symmetrical when the first elastic part 73 elastically deforms, thereby avoiding tilting and offset of the relative movement between the first connecting part 71 and the second connecting part 72, which is beneficial for precise adjustment of the position of the image sensor 1.
[0109] In some embodiments, please refer to Figure 9The first elastic part 73 includes at least one first spring wire. In Embodiment 1, the first elastic part 73 includes four first spring wires 73', which are arranged sequentially and spaced apart between the first connecting part 71 and the second connecting part 72. By setting the first elastic part 73 as the first spring wires 73', the elastic deformation of the first spring wires 73' can realize the relative movement between the first connecting part 71 and the second connecting part 72. By arranging multiple first spring wires 73' at intervals with the first connecting part 71 and the second connecting part 72, frictional resistance and frictional damage caused by contact during the relative movement of the first connecting part 71 and the second connecting part 72 can be avoided. At the same time, it can also realize that the electrical signal passes sequentially through the first connecting part 71 and the first elastic part 73 to the second connecting part 72, avoiding short circuits during the transmission of electrical signals. In addition, the first connector 7 is provided with electrical traces for transmitting electrical signals. Increasing the number of first spring wires 73' allows for better arrangement of electrical traces. If there were only one first spring wire 73', multiple electrical traces would need to be arranged on the same wire, leading to an increase in the width of the first spring wire 73' and a corresponding decrease in its elasticity and elastic force. Increasing the number of first spring wires 73' allows for better arrangement of electrical traces, reduces the width of the first spring wire 73', and increases its deformation capacity, thereby ensuring the elastic deformation capability of the first elastic part 73.
[0110] In some embodiments, please refer to Figure 9The first end 733 is connected to the first connecting part 71, and the second end 734 is connected to the second connecting part 72. The portion between the first end 733 and the second end 734 is the first body 735. The first body 735 is straight and extends along the second direction Y. The distance the first body 735 extends in the second direction Y is greater than or equal to the distance the image sensor 1 extends in the second direction Y, and the vertical projection of the image sensor 1 onto the first body 735 falls within the range of the first body 735. The first body 735 includes a first segment 7351 and a second segment 7352 that are connected to each other. The first segment 7351 extends along the second direction Y, and the second segment 7352 extends along the first direction X, so that the second segment 7352 is bent relative to the first segment 7351. For example, the first segment 7351 and the second segment 7352 are perpendicular to each other. The end of the second segment 7352 furthest from the first segment 7351 is the second end 734, and the end of the first segment 7351 furthest from the second segment 7352 is the first end 733. That is, the first connecting part 71, the first segment 7351, the second segment 7352, and the second connecting part 72 are connected sequentially. When the first elastic part 73 is subjected to a thrust along the first direction X, the first segment 7351 elastically deforms in the first direction X, while the second segment 7352 remains rigid in the first direction X, allowing the second connecting part 72 to move relative to the first connecting part 71 along the first direction X. By making the distance D1 extending of the first body 735 in the second direction Y greater than or equal to the distance D2 extending of the image sensor 1 in the second direction Y, the size of the first body 735 can be maximized when the size of the first connecting member 7 is constant. This results in a longer lever arm and a greater elastic force of the first elastic part 73 in the first direction X, thereby increasing the torque of the first connecting member 7 and improving driving efficiency.
[0111] In some embodiments, please refer to Figure 10 , Figure 10 for Figure 6A schematic diagram of the structure of the first connector 7 in some other possible embodiments. The second connecting portion 72 includes a first extension 725 and a first connecting body 726. There are two first extensions 725. One first extension 725 is located near the third side 723 on the first side 721 and is connected to the first sub-elastic portion 731. The other first extension 725 is located near the fourth side 724 on the second side 722 and is connected to the second sub-elastic portion 732. The first spring wire extends along the second direction Y. The first end 733 is connected to the second connecting piece 712, and the second end 734 is connected to the first extension 725. The side of the first extension 725 connected to the second end 734 is set at an angle to the third side 723, so that the lever arm of the first spring wire around the third side 723 is maximized in the second direction Y. Similarly, the side where the first extension 725 is connected to the first spring wire on the periphery of the fourth side 724 is also set at an angle to the fourth side 724, so that the lever arm of the first spring wire on the periphery of the fourth side 724 in the second direction Y is maximized, thereby enabling the first connector 7 to output a larger torque.
[0112] In one embodiment, the optical image stabilization device 40 further includes a second connector 8, see [link to relevant documentation]. Figure 11 , Figure 11 for Figure 6 The diagram shows the structure of the second connector 8. The second connector 8 includes a third connecting portion 81, a fourth connecting portion 82, and a second elastic portion 83. The third connecting portion 81 is arranged around the periphery of the fourth connecting portion 82 and is spaced apart from the fourth connecting portion 82 by a third gap H3. The third connecting portion 81 has an open frame structure, including a first side frame 811, a second side frame 812, a third side frame 813, and a fourth side frame 814 connected sequentially. The first side frame 811 and the third side frame 813 are arranged opposite each other along the second direction Y, and the second side frame 812 and the fourth side frame 814 are arranged opposite each other along the first direction X. The second elastic portion 83 connects the third connecting portion 81 and the fourth connecting portion 82 and can elastically deform along the second direction Y to realize relative movement between the third connecting portion 81 and the fourth connecting portion 82 along the second direction Y.
[0113] For example, there are two second elastic parts 83, one of which is located between the first frame 811 and the fourth connecting part 82, and the other is located between the third frame 813 and the fourth connecting part 82. By distributing the two second elastic parts 83 on opposite sides of the fourth connecting part 82 in the second direction Y, the third connecting part 81 and the fourth connecting part 82 are subjected to balanced forces in the second direction Y, thereby maintaining balance during movement.
[0114] The second elastic part 83 includes at least one second spring wire 83'. In Embodiment 1, the second elastic part 83 includes four second spring wires 83', which are arranged sequentially and spaced apart between the third connecting part 81 and the fourth connecting part 82. The end of the second spring wire 83' connected to the third connecting part 81 is the third end 831, and the end connected to the fourth connecting part 82 is the fourth end 832. The portion between the third end 831 and the fourth end 832 is the second body 833. The distance extended by the second body 833 in the first direction X is greater than the distance extended by the image sensor 1 in the first direction X, and the vertical projection of the image sensor 1 onto the second body 833 falls within the range of the second body 833. The second body 833 can deform along the second direction Y, thereby allowing relative movement between the third connecting part 81 and the fourth connecting part 82 in the second direction Y. The second body 833 is spaced apart from both the third connecting part 81 and the fourth connecting part 82 to avoid motion interference, friction damage, etc., between the third connecting part 81 and the fourth connecting part 82. By making the distance the second body 833 extends in the first direction X greater than or equal to the distance the image sensor 1 extends in the first direction X, the size of the second body 833 can be maximized when the size of the second connector 8 along the first direction X is constant, so that the elastic force of the second elastic part 83 in the second direction Y is greater and the output torque is also greater.
[0115] In some embodiments, please refer to Figure 11 , Figure 12 and Figure 13 , Figure 12 and Figure 13These are schematic diagrams of the second connector 8 in other possible embodiments. The second main body 833 includes a third segment 8331 and a fourth segment 8332 connected to each other. The third segment 8331 extends along a first direction X, and the fourth segment 8332 extends along a second direction Y. The fourth segment 8332 is rigid and bends at a 90-degree angle relative to the third segment 8331. The end of the third segment 8331 away from the fourth segment 8332 is the third end 831, and the end of the fourth segment 8332 away from the third segment 8331 is the fourth end 832. The fourth connecting portion 82 includes a second connecting main body 821 and a second extension portion 822, which is disposed between the second connecting main body 821 and the second frame 812. The fourth segment 8332 of one second elastic part 83 connects to the second connecting body 821 at a corner away from the second extension 822, and the fourth segment 8332 of the other second elastic part 83 connects to the second extension 822 at a corner away from the second connecting body 821. By providing two second elastic parts 83, and positioning them on opposite sides of the second connecting body 821 along the second direction Y, the interaction force between the third connecting part 81 and the fourth connecting part 82 can be made more uniform and symmetrical, resulting in a more balanced relative movement between them. By providing the second extension 822, the second elastic part 83 can be made larger in the first direction X, thereby enabling it to output a larger torque.
[0116] For example, the fourth connecting portion 82 includes a second extension 822, and the fourth segment 8332 is connected to the second extension 822 via the fourth end 832. In other embodiments, the number, shape, etc., of the second extensions 822 can be reasonably designed according to actual needs so that the size and output force of the second connecting member 8 meet the requirements. Figure 12 As shown, there is one second extension 822, and the side connecting it to the third segment 8331 is set at an angle to the second direction Y, as shown. Figure 14 As shown, there are two second extensions 822, and the two second extensions 822 are centrally symmetrical about the second connecting body 821. By making the second spring wire include a third segment 8331 and a fourth segment 8332, and by providing the second extensions 822 to connect the second elastic part 83 and the fourth connecting part 82, it is beneficial to extend the length of the third segment 8331 in the first direction X. When the second elastic part 83 is subjected to a thrust along the second direction Y, the third segment 8331 elastically deforms in the second direction Y, while the fourth segment 8332 remains rigid in the second direction Y, so that the fourth connecting part 82 and the third connecting part 81 can move relative to each other in the second direction Y. The longer length of the third segment 8331 also results in a larger torque for the second connecting member 8 and higher driving efficiency.
[0117] In some embodiments, please refer to Figure 6 , Figure 10 and Figure 12 The first connecting piece 711 and the second connecting piece 712 include a first region K1 and a second region K2, which are adjacent to each other in the first direction X. The second connecting part 72 and the first elastic part 73 are both located within the first region K1. The second region K2 is a hollow structure and faces the image sensor 1 in the direction perpendicular to the image sensor 1. The second connecting member 8 includes a third region K3 and a fourth region K4 adjacent to each other in the first direction X. A notch is provided on the second frame 812, and the fourth region K4 is arranged between the notch and the third region K3. The fourth region K4 is a hollow structure, and the notch communicates with the fourth region K4. This expands the space available for accommodating the light-directing component 3 in the first direction X within a limited size range, facilitating the installation of the light-directing component 3 and contributing to the miniaturization design of the optical image stabilization device 40. In this embodiment, the second connector 8 is stacked with the first connector 7, and the fourth region K4 is directly opposite and connected to the second region K2 to accommodate the optical component. In this embodiment, the optical component is a light-directing component 3; in other embodiments, the optical component can also be an optical lens group 30, etc. By setting the second region K2 and the fourth region K4 as hollow structures and placing the optical component in the second region K2 and the fourth region K4, the optical component is arranged on the same layer as the driving component M, which helps to reduce the size of the optical image stabilization device 40. Furthermore, by ensuring that both the second region K2 and the fourth region K4 are directly opposite the image sensor 1, it is beneficial for the image sensor 1 to receive external light.
[0118] In some embodiments, please refer to Figure 6 and Figure 14 , Figure 14This is a schematic diagram of the connection structure of the optical image stabilization device 40 in one possible embodiment. The bending portion 52 includes a first bending plate 521 and a second bending plate 522, which are respectively fixed on opposite sides of the drive plate 51 in the second direction Y. The stator 62 is disposed between the first bending plate 521 and the second bending plate 522, so that the magnetic structure 61 is directly opposite to the coil on the drive plate 51. The first connector 7 and the second connector 8 are stacked sequentially on the side of the movable member 5 facing away from the image sensor 1, and the first connector 71 is disposed around the second connector 72 and fixed on the bending portion 52. The second connector 72 is fixedly connected to the fourth connector 82, and the third connector 81 is disposed around the fourth connector 82 and is also connected to the middle frame 42 so that the third connector 81 is fixed to the stator 62. In this embodiment, since the middle frame 42 is disposed outside the bending portion 52, the projection of the second connector 8 in the direction perpendicular to the image sensor 1 is greater than the projection of the first connector 7. The movable part 5 and the first connecting part 7, and the first connecting part 7 and the second connecting part 8, can be fixed by welding, bonding, or other methods. When the drive plate 51 moves along the first direction X, the bending part 52 drives the first connecting part 71 to move along the first direction X. The second connecting part 8 is fixed as a whole by the fixing of the third connecting part 81 to the middle frame 42. The second connecting part 72 is fixed by connecting with the fourth connecting part 82. At this time, the first elastic part 73 bends and deforms along the first direction X, causing relative movement between the first connecting part 71 and the second connecting part 72. When the drive plate 51 moves along the second direction Y, the bending part 52 drives the first connecting part 7 to move as a whole along the second direction Y. At the same time, the first connecting part 7 drives the fourth connecting part 82 to move along the second direction Y through the second connecting part 72. Since the third connecting part 81 is fixed to the middle frame 42, the second elastic part 83 bends and deforms along the second direction Y, realizing relative movement between the third connecting part 81 and the fourth connecting part 82 in the second direction Y. Furthermore, the drive plate 51 is fixedly connected to the first circuit board 63. When the drive plate 51 moves along the first direction X or the second direction Y, the first circuit board 63 moves synchronously with the drive plate 51. By providing a bending portion 52 on the drive plate 51 and placing the stator 62 between the first bending plate 521 and the second bending plate 522, it is beneficial to reduce the installation space of the drive assembly M, thereby reducing the size of the optical image stabilization device 40 in the third direction Z. At the same time, by providing the cooperation of the first connector 7 and the second connector 8 in the optical image stabilization device 40 to adjust the position of the image sensor 1, compared with a structure that uses only one connector, it is beneficial to reduce the size of the optical image stabilization device 40 in the first direction X and the second direction Y.
[0119] In some possible embodiments, please refer to the following: Figure 6 and Figure 17 , Figure 17This is a schematic diagram of the connection structure of the optical image stabilization device 40 in some other possible embodiments. In this embodiment, in the direction perpendicular to the image sensor 1, the projected areas of the first connector 7 and the second connector 8 are equal. The first connector 7 is fixed to the bent portion 52, and the second connector 8 is fixed to the middle frame 42 by other fixing structures, such as... Figure 6 As shown, the fixing structure can be welding material, adhesive, etc. The fixing structure can also be a connecting plate or bracket separate from the middle frame 42, with one end fixedly connected to the fourth connecting part 82 and the other end extending to and fixedly connected to the middle frame 42. In this case, the second connecting member 8 can be accommodated inside the middle frame 42, thereby helping to reduce the size of the optical image stabilization device 40. It is understood that in other embodiments, the size relationship between the first connecting member 7 and the second connecting member 8 can be adjusted accordingly based on changes in the specific installation structure.
[0120] In some embodiments, please Figure 1 5, Figure 1 Figure 5 shows a schematic diagram of the layer structure of the first connector 7 and the second connector 8. The first connector 7 includes a first substrate 74 and a first circuit layer 75. The first circuit layer 75 can be formed by depositing a metal layer, such as copper foil, on the surface of the first substrate 74. The first circuit layer 75 also has a first electrical trace, which sequentially connects the first connecting portion 71, the first elastic portion 73, and the second connecting portion 72. The second connector 8 includes a second substrate 84 and a second circuit layer 85. The second circuit layer 85 can also be formed by depositing a metal layer on the surface of the second substrate 84. The second circuit layer 85 has a second electrical trace, which sequentially connects the fourth connecting portion 82, the second elastic portion 83, and the third connecting portion 81. The first circuit layer 75 and the second circuit layer 85 are disposed adjacent to each other, and the surfaces of the first circuit layer 75 and the second circuit layer 85 opposite each other have pads. By soldering the two layers with conductive solder, the first electrical trace and the second electrical trace can be electrically connected. The first substrate 74 and the second substrate 84 serve to provide support and fixation, while the first circuit layer 75 and the second circuit layer 85 are used to transmit electrical signals, enabling the conductivity of the first connector 7 and the second connector 8. The second electrical trace 85 can also be electrically connected to an external circuit via gold wire connection, wireless connection, or other methods.
[0121] For example, please refer to Figure 16When the first substrate 74 and the second substrate 84 are metal substrates, and the first substrate 74 and the second substrate 84 are disposed adjacently and fixedly connected, conductive through holes K5 can be formed in the adhesive or solder material between the first connector 7 and the second connector 8. The inner wall of the conductive through hole K5 is also coated with an insulating material, and the first circuit layer 75 and the second circuit layer 85 can be electrically connected by filling the conductive through hole K5 with conductive material. After the electrical signal on the bent portion 52 is transmitted to the first substrate 74, it is transmitted sequentially through the first electrical trace and the conductive material in the conductive through hole K5 to the second electrical trace, and finally to the external circuit.
[0122] In some embodiments, please refer to the following: Figure 6 and Figure 14 The external circuit board 2 has multiple metal pins 21. The second connector 8 is electrically connected to the metal pins 21 on the external circuit board 2 via gold wires. The electrical signal from the image sensor 1 is transmitted to the driver board 51 via the first circuit board 63. The driver board 51 transmits the electrical signal to the bending part 52, and the bending part 52 transmits the electrical signal to the first connecting part 71. The electrical signal on the first connecting part 71 is transmitted sequentially to the external circuit board 2 via the first elastic part 73, the second connecting part 72, the fourth connecting part 82, the second elastic part 83, and the third connecting part 81. In other embodiments, the external circuit board 2 can also be directly connected to the second connector 8 to achieve the transmission of electrical signals. By stacking and connecting the first connector 7 and the second connector 8, and making both the first connector 7 and the second connector 8 conductive, the first connector 7 is electrically connected to the image sensor 1, and the second connector 8 is electrically connected to the external circuit board 2, thus achieving the purpose of transmitting electrical signals between the image sensor 1 and the external circuit.
[0123] Figure 14In the illustrated embodiment, the first connecting portion 71 is located around the second connecting portion 72, and the third connecting portion 81 is located around the fourth connecting portion 82. This can be understood as the second connecting portion 72 being located in the middle region of the first connecting member 7, and the fourth connecting portion 82 being located in the middle region of the second connecting member 8. In this embodiment, the middle regions of the first connecting member 7 and the second connecting member 8 are fixedly connected. The edge position of the first connecting member 7 (first connecting portion 71) is fixedly connected to the movable member, and the edge position of the second connecting member 8 (third connecting portion 81) is fixedly connected to the fixing member 6. In other words, the connection points of the first connecting member 7 and the second connecting member 8 with the drive assembly M are located at the outer edge positions. The size of the outer edge positions is larger than that of the middle regions, thus improving the reliability of the fixed connection. Specifically, the first connecting part 71 and the second connecting part 72 are arranged on the same layer, and the third connecting part 81 and the fourth connecting part 82 are arranged on the same layer. While realizing the relative movement of the first connecting part 71 and the second connecting part 72 along the first direction X and the relative movement of the third connecting part 81 and the fourth connecting part 82 along the second direction Y, it is also beneficial to reduce the size of the first connecting member 7 and the second connecting member 8 in the direction perpendicular to the first direction X and the second direction Y, thereby reducing the size of the optical image stabilization device 40.
[0124] Figure 14 In the illustrated embodiment, the first connector 7, the bent portion 52, and the drive plate 51 together enclose a receiving space, the fixing member 6 is located in the receiving space, and the second connector 8 is located on the side of the first connector 7 opposite to the fixing member 6. The stacking direction layout of this solution helps to reduce the thickness of the optical image stabilization device 40 and can ensure the driving force provided by the drive component M, thereby improving the efficiency of the drive component M in moving the image sensor 1.
[0125] For example, please refer to Figure 18 , Figure 18 for Figure 6The diagram shows a partial structural representation of the optical image stabilization device 40 in some other embodiments. A second connecting portion 72 is disposed around the first connecting portion 71, and a fourth connecting portion 82 is disposed around the third connecting portion 81. The first connecting portion 71 is fixedly connected to the bending portion 52, the second connecting portion 72 is fixedly connected to the fourth connecting portion 82, and the third connecting portion 81 can be relatively fixed to the middle frame 42 or the fixing member 6 through other fixing structures. When the drive plate 51 moves along the first direction X, the drive plate 51 drives the first connecting portion 71 to move along the first direction X through the bending portion 52. Since the third connecting portion 81 remains relatively fixed to the fixing member 6, and the second elastic portion 83 is rigid in the first direction X, the fourth connecting portion 82 also remains fixed. Furthermore, since the second connecting portion 72 is fixedly connected to the fourth connecting portion 82, the first connecting portion 71 and the second connecting portion 72 move relative to each other in the first direction X. At this time, the drive plate 51 drives the image sensor 1 to move along the first direction X. When the drive plate 51 moves along the second direction Y, since the first elastic part 73 is rigid in the second direction Y, the drive plate 51 drives the first connecting piece 7 to move along the second direction Y through the bending part 52. The second connecting part 72 drives the third connecting part 81 to move along the second direction Y. Since the third connecting part 81 remains relatively fixed to the fixing part 6, the second elastic part 83 elastically deforms in the second direction Y, and the third connecting part 81 and the fourth connecting part 82 move relative to each other in the second direction Y, so that the drive plate 51 drives the image sensor 1 to move along the second direction Y. In addition, the electrical signal on the image sensor 1 is transmitted to the external circuit board 2 through the first circuit board 63, drive plate 51, bending part 52, first connecting part 71, first elastic part 73, second connecting part 72, fourth connecting part 82, second elastic part 83, and third connecting part 81 in sequence. The third connecting part 81 and the external circuit board 2 can be electrically connected by means of wires, FPC, etc.
[0126] Please refer to the following: Figures 19 to 21 , Figure 19 for Figure 2 The diagram shown illustrates the structure of the camera module 4001 in Embodiment 2. Figure 20 for Figure 19 The diagram shown is an exploded view of the camera module 4001. Figure 21 for Figure 19 The diagram shows a cross-section of the camera module 4001 along the CC direction. In this embodiment, the camera module 4001 is used in a vertical imaging device and includes a module bracket 10, a lens 50, an external circuit board 2, and an optical image stabilization device 40. The lens 50 may include a lens barrel and a lens group installed inside the lens barrel, and is located on the light-incident side of the optical image stabilization device 40. The module bracket 10 is connected to the optical image stabilization device 40 and forms a receiving space G1 to fix the lens 50 within the receiving space G1.
[0127] The module bracket 10 includes a bottom wall 103, a top wall 101, and a side wall 102. The top wall 101 and the side wall 102 enclose each other to form a structure for supporting, fixing, and protecting the lens 50. The top wall 101 and the side wall 102 can be integrally formed or connected by bonding, welding, or snap-fitting. The bottom wall 103 is also stacked and connected to the optical image stabilization device 40 to install and fix the lens 50 to the optical image stabilization device 40. The top wall 101 has a first light-transmitting hole 13, and the bottom wall 103 has a second light-transmitting hole 14. The first light-transmitting hole 13 and the second light-transmitting hole 14 are connected and both are positioned opposite to the optical image stabilization device 40, so that external light enters the lens 50 through the first light-transmitting hole 13, is focused by the lens group inside the lens 50, and then passes through the second light-transmitting hole 14 into the optical image stabilization device 40.
[0128] An external circuit board 2 is disposed on one side of the module bracket 10 and is used to connect to the graphics processor or central processing unit of the electronic device. Simultaneously, the external circuit board 2 is also electrically connected to the optical image stabilization device 40. The connection method can be a wire connection, such as by inserting one end of the wire into the receiving cavity to electrically connect to the optical image stabilization device 40, and leading the other end out to the outside of the module bracket 10 to electrically connect to external circuitry, such as the motherboard of the electronic device. Alternatively, a through-hole can be formed in the module bracket 10, allowing one end of the external circuit board 2 to extend into the module bracket 10 and electrically connect to the optical image stabilization device 40. In other embodiments, other methods can also be used to achieve the electrical connection between the optical image stabilization device 40 and the external circuit board 2.
[0129] In Embodiment 2, the optical image stabilization device 40 includes a voice coil motor. When the camera module 4001 shakes, the voice coil motor compensates for the displacement of the camera module 4001 by driving the movement of the optical image stabilization device 40, thereby improving the image quality of the camera module 4001 when shaking, and realizing the optical image stabilization function. Furthermore, the overall thickness of the optical image stabilization device 40 in Embodiment 2 is relatively small. By setting the optical image stabilization device 40 provided in Embodiment 2 in the camera module 4001, while realizing the optical image stabilization function, it also has the characteristics of simple structure and small size, which is beneficial to meeting the miniaturization design requirements of the camera module 4001.
[0130] Please refer to the following: Figure 22 and Figure 23 , Figure 22 for Figure 20 The diagram shows the overall structure of the optical image stabilization device 40. Figure 23 for Figure 22The diagram shows an exploded view of the optical image stabilization device 40. The optical image stabilization device 40 includes a housing 4, a drive assembly M, an image sensor 1, a first connector 7, and a second connector 8. The first connector 7 and the second connector 8 are force-transmitting structures connected to the drive assembly M, and are also elastic structures. Electrical traces can also be arranged on the first connector 7 and the second connector 8 to achieve electrical connection.
[0131] The housing 4 includes a base plate 41 and a middle frame 42. The base plate 41 and the middle frame 42 are connected to form a receiving cavity with an opening at one end. The drive assembly M and the image sensor 1 are both disposed in the receiving cavity and are connected. The image sensor 1 is disposed on the side of the receiving cavity near the base plate 41. The base plate 41 is used to support and fix the drive assembly M and the image sensor 1. The middle frame 42 provides protection for the drive assembly M and the image sensor 1. The opening of the receiving cavity provides a channel for external light to enter the image sensor 1.
[0132] The optical image stabilization device 40 also includes a first circuit board 63. The first circuit board 63 can be a flexible circuit board, a rigid-flex circuit board, or an integrated circuit board formed by connecting a rigid circuit board and a flexible circuit board. The first circuit board 63 is disposed on the surface of the base plate 41 facing the receiving cavity. The image sensor 1 is fixed on the first circuit board 63 and electrically connected to the first circuit board 63. The connection method can be adhesive bonding, welding, or wire contact connection, etc. By setting the first circuit board 63 to be fixedly connected to the image sensor 1 and electrically connecting the image sensor 1 to the first circuit board 63, while fixing the image sensor 1, the electrical signal of the image sensor 1 can also be transmitted to the external circuit through the connection of the first circuit board 63 to the external circuit.
[0133] Drive component M includes moving part 5 and fixed part 6, please refer to both. Figure 23 and Figure 27 , Figure 27 for Figure 23 The diagram shows the structure of the movable component 5. The movable component 5 includes a drive plate 51 and a bending portion 52, which are fixedly connected to each other. The drive plate 51 and the bending portion 52 can be integrally formed. A coil 53 is provided on the drive plate 51, and the bending portion 52 is used to connect to the first connector 7. In this embodiment, the drive plate 51 is a second circuit board, which has conductive properties to transmit electrical signals. The drive plate 51 has a U-shaped structure, including a first side 511 and a second side 512 arranged opposite each other along the second direction Y, and a third side 513 and a fourth side 514 arranged opposite each other along the first direction X. A coil 53 is provided on each of the first side 511, second side 512, third side 513, and fourth side 514, and the coils 53 on the four sides form two coil groups arranged perpendicularly to each other.
[0134] The fixing member 6 includes a magnetic structure 61 and a stator 62. The stator 62 is a "hui"-shaped structural fixing frame identical to the driving plate 51. In this embodiment, the magnetic structure 61 is embedded in the four side edges of the stator 62 to be disposed opposite to the coil 53 on the driving plate 51, so as to form two sets of mutually perpendicular magnetic fields. When an electric current is applied to the coil 53, the coil 53 moves under the action of magnetic thrust and drives the driving plate 51 to move. In other embodiments, the magnetic structure 61 can also be fixed on the stator 62 by other means such as bonding or clamping.
[0135] Exemplarily, a coil 53 is provided on each side edge of the driving plate 51. Among them, the coils 53 on the first side edge 511 and the second side edge 512 are used to control the driving plate 51 to move along the second direction Y, and the coils 53 on the third side edge 513 and the fourth side edge 514 are used to control the driving plate 51 to move in the first direction X. When the same-direction current is applied to the coils 53 on the first side edge 511 and the second side edge 512 and the coils 53 on the third side edge 513 and the fourth side edge 514 are not powered on, the coil 53 drives the driving plate 51 to move along the second direction Y under the action of magnetic force; when the opposite-direction current is applied to the coils 53 on the first side edge 511 and the second side edge 512 and the coils 53 on the third side edge 513 and the fourth side edge 514 are not powered on, the coil 53 drives the driving plate 51 to flip along the third direction Z under the action of magnetic force, where the third direction Z is perpendicular to the first direction X and the second direction Y; when the same-direction current is applied to the coils 53 on the third side edge 513 and the fourth side edge 514 and the coils 53 on the first side edge 511 and the second side edge 512 are not powered on, the coil 53 drives the driving plate 51 to move along the first direction X under the action of magnetic force.
[0136] In some embodiments, please also refer to Figures 23 to 26 , Figure 24 For Figure 23 the schematic connection structure diagram of the first connecting member 7 and the second connecting member 8 in some embodiments shown in Figure 24 and Figure 25 are both Figure 23 the schematic connection structure diagram of the first connecting member 7 and the second connecting member 8 in some other embodiments shown in. The first connecting member 7 and the second connecting member 8 are both hollow frame structures, and the first connecting member 7 and the second connecting member 8 enclose a light-transmitting area K6. Exemplarily, as Figure 24 shown, the light-transmitting area K6 is used to accommodate the image sensor 1. As Figure 25 shown, the light-transmitting area K6 is used to accommodate an optical component, such as the optical lens group 30, and the optical component is disposed on the incident light path of the image sensor 1. As Figure 26 shown, the space within the light-transmitting area K6 is the optical path between the optical component and the image sensor 1.
[0137] Please refer to Figure 28, Figure 28 yes Figure 23 The diagram shows the structure of the first connector 7 in some embodiments. The first connector 7 includes a first connecting portion 71, a second connecting portion 72, and a first elastic portion 73. The first elastic portion 73 is disposed between the first connecting portion 71 and the second connecting portion 72 and connects the first connecting portion 71 and the second connecting portion 72. The first connecting portion 71 includes a first connecting piece 711, a second connecting piece 712, a third connecting piece 713, and a fourth connecting piece 714. The first connecting piece 711 and the second connecting piece 712' are disposed opposite to each other, and the third connecting piece 713' and the fourth connecting piece 714' are disposed opposite to each other. The second connecting portion 72 includes a fifth connecting piece 721', a sixth connecting piece 722', a seventh connecting piece 723', and an eighth connecting piece 724'. A first connecting piece 711 is located around the fifth connecting piece 721' and is spaced apart from it by a gap H1'. A second connecting piece 712 is located around the sixth connecting piece 722' and is spaced apart from it by a gap H2'. A third connecting piece 713 is located around the seventh connecting piece 723' and is spaced apart from it by a gap H3'. A fourth connecting piece 714 is located around the eighth connecting piece 724' and is spaced apart from it by a gap H4'. By making the first connecting portion 71 and the second connecting portion 72 a frame shape with closed outer edges and a hollow center, the closed outer edges can be used for fixed connection between the second connecting portions 72, and the hollow center structure is directly opposite the image sensor 1, allowing light to pass through. Furthermore, the gap between the first connecting part 71 and the second connecting part 72 also avoids problems such as motion interference and short circuit between the first connecting part 71 and the second connecting part 72.
[0138] The first elastic portion 73 includes a first sub-elastic portion 731 and a second sub-elastic portion 732. The first sub-elastic portion 731 is located between the third connecting piece 713 and the seventh connecting piece 723', and connects the third connecting piece 713 and the seventh connecting piece 723'. The second sub-elastic portion 732 is located between the fourth connecting piece 714 and the eighth connecting piece 724', and connects the fourth connecting piece 714 and the eighth connecting piece 724'. The first sub-elastic portion 731 includes a first spring wire. The first end 733 of the first spring wire is connected to the first connecting portion 71, and its connection position is located near the third connecting piece 713 of the first connecting piece 711. The second end 734' is connected to the sixth connecting piece 722, and its connection position is located near the seventh connecting piece 723 of the sixth connecting piece 722. A first main body is disposed between the third connecting piece 713 and the seventh connecting piece 723, and the first main body extends in a strip shape along the second direction Y, which helps to ensure the stability of the direction of the elastic force and ensure the direction of the force. Air gaps exist between the first main body and both the third connecting piece 713 and the seventh connecting piece 723 to avoid motion interference with the first connecting portion 71. The first main body includes a first segment 7351 extending along the second direction Y and a second segment 7352 extending along the first direction X. The first segment 7351 and the second segment 7352 are connected, and the second segment 7352 is bent at a right angle relative to the first segment 7351. When the first elastic portion 73 is subjected to a thrust along the first direction X, the first segment 7351 elastically deforms in the first direction X, while the second segment 7352 remains rigid in the first direction X, allowing the second connecting portion 72 to move relative to the first connecting portion 71 along the first direction X. By including the bent and connected first segment 7351 and second segment 7352, with the first segment 7351 used for elastic deformation and the second segment 7352 used for fixation, it is beneficial to extend the length of the first elastic portion 73 in the first direction X, thereby enabling the output of a larger torque and higher driving efficiency.
[0139] Please refer to the following: Figure 29 and Figure 30 , Figure 29 This is a structural schematic diagram of the first connector 7 in some possible embodiments. Figure 30 This is a schematic diagram of the structure of the first connector 7 in some other possible embodiments. The second connector 72 includes a first connector body 726 and a first extension 725. In this embodiment, the fifth connector piece 721 and the sixth connector piece 722 are used as examples for description. Both first connector bodies 726 and both first extensions 725 extend along the first direction X. The edge at the connection between the first extension 725 and the first elastic part 73 is as follows. Figure 26 The hypotenuse shown, which is inclined at an angle to the first direction X, can also be as follows: Figure 27The side shown is parallel to the first direction X. When the second connecting portion 72 is provided with the first extension portion 725, the second spring wire only includes the first segment 7351, and the first extension portion 725 is used to replace the rigid connection function of the second segment 7352. It is understood that in other embodiments, the number and shape of the first extension portion 725 can be designed according to actual needs.
[0140] In some embodiments, please refer to the following: Figure 23 and Figure 31 , Figure 31 for Figure 23 The diagram shows the structure of the second connector 8 in some embodiments. The second connector 8 is disposed between the first connector 7 and the movable member 5. The second connector 8 includes a third connecting portion 81, a fourth connecting portion 82, and a second elastic portion 83. Both the third connecting portion 81 and the fourth connecting portion 82 are frame-shaped with closed outer edges and hollowed-out middle sections. The second elastic portion 83 is disposed between the third connecting portion 81 and the fourth connecting portion 82 and connects the third connecting portion 81 and the fourth connecting portion 82. The second elastic portion 83 includes a third sub-elastic portion 831 and a fourth sub-elastic portion 832. The first segment 8311 of the third sub-elastic portion 831 extends along the first direction X, and the second segment 8312 extends along the second direction Y. The third sub-elastic portion 831 and the fourth sub-elastic portion 832 are symmetrically disposed on both sides of the fourth connecting portion 82 along the second direction Y. The structure of the third sub-elastic portion 831 and the fourth sub-elastic portion 832 is the same as the structure of the first elastic portion 73, and can be referred to accordingly, and will not be described again here.
[0141] When the second elastic part 83 is subjected to a thrust along the second direction Y, the first segment 8311 elastically deforms along the second direction Y, while the second segment 8312 remains rigid along the second direction Y, so that the fourth connecting part 82 and the third connecting part 81 move relative to each other along the second direction Y. By providing two second elastic parts 83 and placing them on opposite sides of the fourth connecting part 82 along the second direction Y, the interaction force between the third connecting part 81 and the fourth connecting part 82 can be made more uniform and symmetrical, resulting in a more balanced relative movement between them.
[0142] In other embodiments, the fourth connecting part 82 may also include a second connecting body and a second extension, the number and structure of which can be set with reference to the number and structure of the first connecting body and the first extension of the first connecting member 7.
[0143] Please refer to the following: Figure 22 , Figure 32 and Figure 33 , Figure 32 for Figure 22 A schematic diagram of the structure cut along point DD. Figure 33 for Figure 22A structural schematic diagram cut along EE. The second connector 8 is stacked on top of the first connector 7. The movable part 5 includes a bent portion 52, which extends from the drive plate 51 toward the side where the first connector 7 is located. There are two bent portions 52, which are symmetrically arranged on both sides of the drive plate 51 along the second direction Y. The first connector 7 is connected to the bent portions 52 and encloses a receiving cavity with openings at both ends. The two openings are located on both sides of the drive plate 51 along the first direction X. The second connector 8 is disposed in the receiving cavity and is connected to the middle frame 42 through the openings at both ends of the receiving cavity. Figure 32 and Figure 33 In the illustrated scheme, the first connector 7, the bent portion 52, and the drive plate 51 together enclose a receiving space, the second connector 8 is disposed within the receiving space, and the fixing member 6 is located on the side of the drive plate 51 opposite to the second connector 8. By placing the second connector 8 within the receiving space and the fixing member 6 on the side of the drive plate 51 opposite to the second connector 8, this scheme also achieves a more compact structure for the optical image stabilization device, thus reducing its overall size.
[0144] In Embodiment 2, the first connecting part 71 is disposed around the second connecting part 72, and the third connecting part 81 is disposed around the fourth connecting part 82. The first connecting part 71 is fixedly connected to the bending part 213, the second connecting part 72 is fixedly connected to the fourth connecting part 82, and the third connecting part 81 is fixedly connected to the middle frame 42. When the drive plate 51 moves along the first direction X, the bending part 213 drives the first connecting part 71 to move along the first direction X. Since the second elastic part 83 is rigid in the first direction X, and the third connecting part 81 is fixed to the middle frame 42, the second connecting piece 8 remains fixed as a whole. The second connecting part 72 is fixedly connected to the fourth connecting part 82 and remains fixed. At this time, the first elastic part 73 deforms along the first direction X, and the first connecting part 71 and the second connecting part 72 move relative to each other in the first direction X. When the drive plate 51 moves along the second direction Y, the bending portion 213 drives the first connecting portion 71 to move along the second direction Y. Since the first elastic portion 73 is rigid in the second direction Y, the bending portion 213 drives the entire first connecting piece 73 to move along the second direction Y. The second connecting portion 72 drives the fourth connecting portion 82 to move along the second direction Y. Since the third connecting portion 81 is fixedly connected to the fixing member 6, the second elastic portion 83 deforms along the second direction Y, causing the fourth connecting portion 82 and the third connecting portion 81 to move relative to each other in the second direction Y. In addition, the side of the first connecting piece 7 facing away from the drive plate 51 is fixedly connected to the first circuit board 63. When the drive plate 51 drives the first connecting portion 71 to move, the first connecting portion 71 drives the first circuit board 63 to move synchronously, thereby achieving the purpose of moving the image sensor 1.
[0145] Similarly, the second connecting part 72 can be disposed around the first connecting part 71, and the fourth connecting part 82 can be disposed around the third connecting part 81. The specific connection structure can be referred to the description in Embodiment 1, and will not be repeated here.
[0146] In some embodiments, please refer to Figure 33 and Figure 34 , Figure 34 yes Figure 22 The diagram shows a partial structural schematic of the optical image stabilization device 40 in some embodiments. The first connector 7 includes a first substrate 74, a first circuit layer 75, and a third circuit layer 76. The first circuit layer 75 and the third circuit layer 76 are respectively disposed on two opposite surfaces of the first substrate 74. The first circuit layer 75 has a first electrical trace, and the third circuit layer 76 has a second electrical trace. A conductive via K5 is formed on the first substrate 74, penetrating the first circuit layer 75, the first substrate 74, and the third circuit layer 76. An insulating layer is coated inside the conductive via K5, and then a conductive material is filled in. The insulating layer insulates the conductive material from the first substrate 74, and the conductive material enables electrical connection between the first circuit layer 75 and the third circuit layer 76. The electrical signal from the image sensor 1 is transmitted sequentially through the first circuit board 63, the movable member 5, the first circuit layer 75, and the third circuit layer 76 to the fourth connector 82, and then sequentially through the second elastic part 83 and the third connector 81 to the external circuit.
