Description

Technical Field

[0001] This application belongs to the field of camera module technology, and particularly relates to a stabilization device, an optical image stabilization camera module, and an electronic device. Background Technology

[0002] Camera modules are widely used in various terminal devices to achieve shooting functions. During terminal use, various scenarios are encountered, such as static shooting and shooting while in motion, where the degree of camera shake varies significantly. To compensate for the impact of shake on the shooting module, various forms of image stabilization mechanisms are typically incorporated, such as lens-shift image stabilization and chip-shift image stabilization. Lens-shift image stabilization primarily achieves image stabilization compensation by using a dedicated moving structure to translate or tilt the lens; chip-shift image stabilization typically achieves image stabilization compensation by using a moving structure to translate or rotate the chip.

[0003] Due to the limited internal space of the module, the space for image stabilization mechanisms to move is limited. Image stabilization mechanisms that rely on translation or deflection typically offer a compensation angle of around 1-1.5°. Lens deflection, in particular, is relatively large and has a limited range of movement and deflection. While it provides some compensation for normal static or minor shaking, it usually requires a compensation angle of 3-5° for motion or significant vibrations. Existing chip-shifting and lens-shifting image stabilization mechanisms in camera modules cannot meet the stabilization needs of conditions with large shaking, such as motion, thus limiting the application scenarios of optical image stabilization camera modules and hindering their widespread adoption.

[0004] Therefore, a gimbal based on tilt-shift image stabilization is typically used. The camera module is mounted entirely on the gimbal, or the frame structure of the camera module is integrated with part of the gimbal structure and then mounted onto the device, which increases the stabilization angle to some extent. However, the gimbal structure needs to deflect in two mutually perpendicular directions, requiring two support structures. The camera module is rotatably connected to the first support via a hinge, and a set of deflection drive components is connected between the first support and the camera module. The first support is then rotatably connected to the second support via a hinge, and a second set of deflection drive components is connected between the second support and the first support to ensure that the camera module can deflect around two set hinges. Consequently, a larger installation space is required to accommodate the gimbal support structure and the camera module, which limits the application range of the camera module. Summary of the Invention

Therefore,

[0006] One aspect of this application provides a shake-proof device, comprising: a mounting base, an elastic support member, an elastic clamping member, a deflector member, a first deflection drive assembly, and a second deflection drive assembly;

[0007] The elastic support member and the elastic clamping member are disposed opposite to each other on the mounting base;

[0008] The deflector is provided with a first rotating shaft and a second rotating shaft that are perpendicular to each other. The two ends of the first rotating shaft and the two ends of the second rotating shaft respectively abut against an elastic support and are respectively pressed by an elastic clamping member.

[0009] The first deflection drive assembly is connected between the mounting base and the deflector to drive the deflector to rotate about the first rotating shaft.

[0010] The second deflection drive assembly is connected between the mounting base and the deflector to drive the deflector to rotate about the second shaft.

[0011] In some embodiments, the mounting base has a mounting groove, and the elastic support and the elastic clamping member are disposed within the mounting groove.

[0012] In some embodiments, the elastic support and the elastic clamping member are integrally formed as an elastic member, and the elastic member has a pivot hole, the end of the first pivot is rotatably disposed in the pivot hole.

[0013] In some embodiments, the anti-shake device further includes: a deflector;

[0014] The deflection seat is rotatably mounted on the mounting base;

[0015] The deflection seat has a receiving groove, and the elastic support member and the elastic clamping member are disposed opposite to each other in the receiving groove.

[0016] In some embodiments, the deflector seat includes: a body and a deflection shaft;

[0017] The first end of the deflection shaft is connected to the main body, and the second end of the deflection shaft is rotatably connected to the mounting base;

[0018] The receiving groove is disposed on the main body.

[0019] In some embodiments, the deflector includes: a body and a ball head;

[0020] The two ends of the ball joint are respectively connected to the main body and the mounting base.

[0021] In some embodiments, the elastic support and the elastic clamping member are springs or elastic rubber components.

[0022] In some embodiments, the first deflection drive assembly includes a magnet and a coil;

[0023] The magnet and the coil are arranged opposite to each other, with the magnet mounted on one of the deflector and the mounting base, and the coil mounted on the other.

[0024] In another aspect of this application, an optical image stabilization camera module is provided, comprising: a camera module and the aforementioned image stabilization device;

[0025] The camera module is mounted on the deflector.

[0026] In another aspect of this application, an electronic device is provided, including the aforementioned optical image stabilization camera module.

[0027] The embodiments of this application have at least the following beneficial effects:

[0028] The image stabilization device, optical image stabilization camera module, and electronic device provided in this application embodiment have two perpendicular first and second rotating shafts on a deflector. An elastic support is provided on a mounting base corresponding to each end of the first and second rotating shafts to abut and support the first and second rotating shafts. An elastic clamping member is also provided on each shaft to clamp the ends of the first and second rotating shafts respectively, thereby allowing both ends of the first and second rotating shafts to elastically shift and reset under external force. This enables the deflector to... The device can independently perform deflection operations around the first and second rotating axes, and can also simultaneously perform deflection operations of the deflecting element around the first and second rotating axes respectively. Specifically, when the deflecting element is driven to deflect around the first rotating axis by the first deflection drive assembly, an elastic support member and an elastic clamping member are respectively pressed against both ends of the first rotating axis. The elastic support member and the elastic clamping member at both ends of the first rotating axis basically maintain their current shape, similar to the rigid rotation support structure of a conventional gimbal bracket. However, in this embodiment, the second deflection drive assembly can also be used simultaneously. The deflector is driven to deflect around the second axis. At this time, both ends of the first axis press against another elastic support and another elastic clamping member, respectively, achieving elastic displacement and obtaining sufficient deflection space to complete the deflection operation around the second axis. However, the rigid rotational support structure of the conventional gimbal bracket does not have deflection space and cannot implement deflection, thus requiring the deflection on the two axes to be decomposed into two independent brackets. Therefore, this application obtains four elastic support structures by setting elastic support and elastic clamping member groups at both ends of the mutually perpendicular first and second axes. This invention achieves the operation of deflecting components around two vertical axes within a single bracket structure. Therefore, after mounting the camera module onto the deflecting components, the structural complexity and size are relatively simplified. This makes it easier to achieve a larger stabilization angle with less installation space, making it suitable for installation and use in a wider range of products and expanding its application scope. On the other hand, by utilizing the linear deformation characteristics of the elastic component, the deflection attitude change of the deflecting component can be achieved linearly and smoothly, avoiding the impact of instantaneous vibration during the deflection adjustment process on the shooting quality. Thus, it can balance the stabilization effect and the shooting quality to a certain extent. Attached Figure Description

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0052] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0053] This application is described below with reference to the accompanying drawings and specific embodiments:

[0054] Camera modules typically incorporate image stabilization mechanisms to ensure image quality. These mechanisms generally employ two optical image stabilization principles: translation-shift and tilt-shift. Translation-shift refers to moving the lens, image sensor, or rotating the image sensor to change the optical axis, keeping the optical axis direction constant to meet stabilization requirements. However, its stabilization compensation angle is generally around 1-1.5°, making it suitable for still shooting and situations with minor shaking. Tilt-shift, on the other hand, involves tilting the lens, image sensor, or both the lens and image sensor to change the tilt angle of the optical axis, resulting in a certain angle of tilt to meet stabilization requirements. Its stabilization compensation angle can typically reach 3-5° or even larger, making it better suited for shooting with greater shaking, such as during motion.

[0055] However, when implementing tilt-shift image stabilization mechanisms, it is often necessary to set up mechanisms that rotate around two vertical axes, each independently performing two deflection operations around the axes. For example, taking a fully tilted camera module, two supports are typically used. The first support can deflect relative to the second support around an axis, and a deflection drive mechanism is connected between them. The entire camera module is rotatably connected to the first support via a second axis, and a deflection drive mechanism is also connected between them. Thus, by the camera module deflecting relative to the first support, and the first support and the entire camera module deflecting relative to the second support, the camera module's spatial deflection around two vertical axes is achieved, completing the image stabilization operation; a typical example is a gimbal-type image stabilization mechanism.

[0056] This results in the need for two supports to achieve a larger angle of image stabilization compensation, and the two supports must have sufficient deflection operation space. This makes the overall structure of the camera module equipped with the tilt-shift image stabilization mechanism larger, requiring more installation and operation space. This is not conducive to the widespread adaptation to the needs of various terminals and to some extent limits the application range of this type of camera module.

[0057] To address this, this application provides a stabilization device that utilizes an elastic support structure to support two mutually perpendicular rotating axes of a camera module. This allows the module to deflect around the two perpendicular rotating axes within a single support structure, simplifying the tilt-shift stabilization structure and reducing the installation space requirements to some extent. This also improves the limited application range of such tilt-shift stabilization camera modules.

[0058] The details will be explained below.

[0059] See Figure 1 , Figure 2 , Figure 3 and Figure 13The image stabilization device provided in this embodiment includes a mounting base 100 and a deflector 200. The mounting base 100 serves as a basic support structure for implementing tilt-shift operations, supporting the deflector 200 and other functional structures and components for tilt-shift operations. The deflector 200 is a structural body that can deflect relative to the mounting base 100 around two mutually perpendicular axes. It can be used to fix and install a complete camera module product, or it can be part of the camera module product, such as a housing, mounting base, or other components, used to support and install other functional structures and components. This embodiment does not impose specific limitations. In the following description, for ease of explanation, the deflector 200 refers to a complete camera module product with shooting capabilities.

[0060] On the other hand, considering that the image stabilization device does not have a specific lower and upper part or directionality when it is assembled on the terminal, the direction perpendicular to the two rotating axes is defined as vertical for ease of description, which is also the optical axis direction of the camera module; however, the above settings are only for ease of description and are not specifically limited.

[0061] See Figure 5 , Figure 7 , Figure 10 and Figure 12 In the anti-shake device involved in this example, in order to support the deflector 200 and deflect it about two mutually perpendicular rotating shafts, the deflector 200 is provided with two mutually perpendicular rotating shafts, namely a first rotating shaft 210 and a second rotating shaft 220, and is connected to the mounting base 100 through the first rotating shaft 210 and the second rotating shaft 220, and can achieve relative deflection; for this purpose, both ends of the first rotating shaft 210 and the second rotating shaft 220 should be connected to the mounting base 100, and both can rotate relative to the mounting base 100.

[0062] Correspondingly, the mounting base 100 is provided with a space for the deflector 200 to deflect, and a plurality of elastic support members are provided in the corresponding space, each independently supporting the ends of the first rotating shaft 210 and the second rotating shaft 220. Therefore, the elastic support members can be set to four, each supporting the ends of the first rotating shaft 210 and the second rotating shaft 220. At the same time, a plurality of elastic clamping members are also provided, each independently clamping the ends of the first rotating shaft 210 and the second rotating shaft 220, so that the ends of the first rotating shaft 210 and the second rotating shaft 220 are stably and elastically abutted between the elastic clamping members and the elastic support members, and can rotate. Therefore, the elastic clamping members can also be set to four, each clamping the ends of the first rotating shaft 210 and the second rotating shaft 220.

[0063] Considering that the first rotating shaft 210 and the second rotating shaft 220 have different operating postures, and their corresponding support structures are also different, the plurality of elastic support members and the elastic clamping members can be divided into a first elastic support member 510 and a first elastic clamping member 520 corresponding to the first rotating shaft 210, and a second elastic support member 610 and a second elastic clamping member 620 corresponding to the second rotating shaft 220. There can be two of each of the first elastic support member 510 and the first elastic clamping member 520, symmetrically arranged on opposite sides of the mounting base 100; similarly, there can also be two of each of the second elastic support member 610 and the second elastic clamping member 620, symmetrically arranged on opposite sides of the mounting base 100.

[0064] When the deflector 200 deflects around the first rotating shaft 210, one of the two ends of the second rotating shaft 220 compresses the second elastic support 610 on its corresponding side, and the other compresses the second elastic clamping member 620 on its corresponding side, until a steady state is reached and maintained; similarly, when the deflector 200 deflects around the second rotating shaft 220, one of the two ends of the first rotating shaft 210 compresses the first elastic support 510 on its corresponding side, and the other compresses the first elastic clamping member 520 on its corresponding side, until a steady state is reached and maintained.

[0065] It is worth noting that, considering that both the elastic support and the elastic clamping components can elastically deform, both ends of the first rotating shaft 210 and the second rotating shaft 220 can elastically shift. Therefore, the deflection process of the deflector 200 around the first rotating shaft 210 and the second rotating shaft 220 can be synchronously achieved during the deflection process of the deflector 200 relative to the mounting base 100. That is, the two deflection processes can be integrated, and both involve the deflector 200 deflecting relative to the mounting base 100. This is unlike the rigid fixed mode in gimbal structures, where the two deflection processes are implemented independently based on two supports due to the limitation of the rotating shaft structure. Therefore, the deflection structure is simplified, and the space occupied is reduced. At the same time, by deflecting around two vertical rotating shafts, a larger anti-shake compensation angle can be obtained, thus balancing improved anti-shake compensation performance and reduced space occupation, making it more suitable for use in various terminal products and improving the problem of limited application range.

[0066] In order to drive the deflector 200 to deflect relative to the mounting base 100 around the first rotating shaft 210 and the second rotating shaft 220 respectively, a first deflection drive assembly 300 and a second deflection drive assembly 400 are connected between the deflector 200 and the mounting base 100 to implement deflection drive along a set direction.

[0067] Generally, the driving force of the first deflection drive assembly 300 acting on the deflector 200 should have a component along the circumferential direction of the first rotation axis 210 to ensure that the deflector 200 can deflect around the first rotation axis 210; the driving force of the second deflection drive assembly 400 acting on the deflector 200 should have a component along the circumferential direction of the second rotation axis 220 to ensure that the deflector 200 can deflect around the second rotation axis 220.

[0068] This embodiment of the application achieves elastic displacement of the deflector's axis by setting multiple elastic support members and elastic clamping members between the mounting base and the axis of the deflector. This differs from the rigid support mode of the axis in the gimbal structure, which prevents the axis from moving. This allows the deflector to deflect synchronously around two axes, instead of decomposing the two deflection processes on two supports as in the gimbal structure. This simplifies the image stabilization structure to a certain extent, reduces the overall structural size of the camera module, and reduces the required installation and operation space, making it more widely applicable and with a wider range of applications. On the other hand, the deformation and displacement of multiple elastic support members and elastic clamping members make the attitude and position changes of the deflector linear and smooth, reducing the impact of instantaneous vibration during the image stabilization compensation process on the shooting quality. Thus, it can improve both the image stabilization effect and the shooting quality to a certain extent.

[0069] See Figure 5 and Figure 13 In some embodiments, to further reduce the overall size of the structure, a mounting groove 110 can be formed on the mounting base 100, and the first elastic support 510 and the first elastic clamping member 520, which elastically abut against the ends of the first rotating shaft 210 and the second rotating shaft 220, can be placed in one of the mounting grooves 110, while the second elastic support 610 and the second elastic clamping member 620 can be disposed in another mounting groove 110. By using the slotted mounting method, the gap between the deflector 200 and the mounting base 100 can be reduced, thereby reducing the overall size of the mounting base 110 to a certain extent.

[0070] Meanwhile, the mounting groove 110 can protect the first elastic support 510, the first elastic clamping member 520, the second elastic support 610, and the second elastic clamping member 620, respectively, reducing the adverse effects of interference from other components on the elastic support and deflection process. To a certain extent, it can also constrain the ends of the first rotating shaft 210 and the second rotating shaft 220, achieving a certain degree of limitation and reducing the risk of the rotating shaft ends becoming displaced due to distance impacts or other factors.

[0071] In some embodiments, considering that when the deflector 200 rotates simultaneously around the first pivot 210 and the second pivot 220, the first pivot 210 and the second pivot 220 will be subjected to the resultant force from the deflector 200, and the resultant force will change in real time with the deflection process, there is a risk that the end of the first pivot 210 will slip off between the first elastic support 510 and the first elastic clamping member 520, and the end of the second pivot 220 will also slip off between the second elastic support 610 and the second elastic clamping member 620, which will lead to the deterioration or even loss of the anti-shake function.

[0072] Therefore, the first elastic support 510 and the first elastic clamping member 520 can be integrally formed into an elastic member, and a pivot hole can be provided on the elastic member so that the end of the first pivot 210 can be stably rotatably disposed in the pivot hole, thereby meeting the requirement of stable rotation.

[0073] Similarly, the second elastic support 610 and the second elastic clamping member 620 can be integrally formed as an elastic member, and a pivot hole can be provided on the elastic member so that the end of the second pivot 220 can be stably rotatably disposed in the pivot hole, thereby meeting the requirements for stable rotation.

[0074] See Figure 7 , Figure 10 and Figure 11 In some embodiments, the size of the pivot hole should be slightly larger than the size of the portion of the first pivot 210 embedded between the first elastic support 510 and the first elastic clamping member 520. That is, the end of the first pivot 210 is provided with a first pivot embedding portion 211, and the size of the first pivot embedding portion 211 is slightly smaller than the size of the pivot hole, so as to maintain a stable rotation gap.

[0075] Similarly, the size of the pivot hole should be slightly larger than the size of the portion of the second pivot 220 embedded between the second elastic support 610 and the second elastic clamping member 620. That is, the end of the second pivot 220 is provided with a second pivot embedding part 221, and the size of the second pivot embedding part 221 is slightly smaller than the size of the pivot hole, so as to maintain a stable rotation gap.

[0076] In some embodiments, in order to ensure the smooth rotation of the first shaft embedding part 211 and the second shaft embedding part 221 and reduce friction and wear, a lubricating coating may be provided on the rotating circumferential surface of the first shaft embedding part 211 and the second shaft embedding part 221, or the first shaft embedding part 211 and the second shaft embedding part 221 may be directly formed by self-lubricating material.

[0077] In some embodiments, the first rotating shaft 210 can be configured as a variable cross-section cylindrical structure, that is, the diameter of the first rotating shaft embedding part 211 is smaller than the diameter of the main body of the first rotating shaft 210. This avoids the first rotating shaft embedding part 211 being too large and affecting the deformation posture of the first elastic support 510 and the first elastic clamping member 520. At the same time, it can accommodate the first rotating shaft 210 main body to be formed or installed on the deflector 200 with a relatively large diameter, thereby facilitating forming or installation.

[0078] Similarly, the second rotating shaft 220 can be configured as a variable cross-section cylindrical structure, that is, the diameter of the second rotating shaft embedding part 221 is smaller than the diameter of the main body of the second rotating shaft 220. This avoids the second rotating shaft embedding part 221 being too large and affecting the deformation posture of the second elastic support 610 and the second elastic clamping part 620. At the same time, it can accommodate the second rotating shaft 220 main body to be formed or installed on the deflection member 200 with a relatively large diameter, thereby facilitating forming or installation.

[0079] See Figure 1 , Figure 2 , Figure 4 , Figure 11 and Figure 12 In some embodiments, the first deflection drive component 300 and the second deflection drive component 400 may adopt a drive mechanism based on the principle of force on a current-carrying coil in a magnetic field to achieve contactless drive and minimize the impact of the drive structure on the deflection element 200.

[0080] Specifically, the first deflection drive assembly 300 includes a first deflection drive coil 310 and a first deflection drive magnet 320, and the first deflection drive coil 310 and the first deflection drive magnet 320 are respectively disposed opposite to each other on the deflection member 200 and the mounting base 100. By adjusting the magnitude and direction of the current applied to the first deflection drive coil 310, different magnetic field forces are obtained to drive the deflection member 200 to deflect in different amplitudes and directions.

[0081] The first deflection drive coil 310, as an active device, can be disposed on the deflection member 200 and connected to the module circuit of the camera module fixed on the deflection member 200. It can obtain a controlled loading current signal through its module circuit to communicate with the outside world, thereby simplifying the communication structure. Correspondingly, the first deflection drive magnet 320 is disposed on the mounting base 100. Thus, the mounting base 100 and the first deflection drive magnet 320 thereon are both passive devices, and there is no need to consider electrical connection operations during assembly, thereby simplifying the assembly operation.

[0082] Alternatively, the first deflection drive coil 310 can be mounted on the mounting base 100 and independently connected to the control circuit of the image stabilization device to obtain a controlled loading current signal. Correspondingly, the first deflection drive magnet 320, as a passive device, is directly mounted on the deflection component 200. Thus, during assembly, no additional electrical connection processing is required between the deflection component 200 and the camera module on it and the image stabilization device, which can simplify the processing to a certain extent.

[0083] In some embodiments, the first deflection drive coil 310 can be configured as two sets of drive coils, namely a first drive coil 311 and a second drive coil 312. The first drive coil 311 and the second drive coil 312 can be symmetrically arranged on both sides of the axis of the first rotating shaft 210. By applying currents in opposite directions to the first drive coil 311 and the second drive coil 312, two forces driving the rotation of the first rotating shaft 210 of the deflector 200 can be applied to both sides, improving the uniformity of the force. This makes the magnitude of the forces acting on the second elastic support 610 and the second elastic clamping member 620 equal, thereby keeping the center of the deflector 200 stable. This ensures that the tilt shift operation is only a change in angle, restricts movement in other directions, maintains the stability of the position and attitude of the deflector, and ensures the shooting quality.

[0084] In some embodiments, the second deflection drive assembly 400 includes a second deflection drive coil 410 and a second deflection drive magnet 420, and the second deflection drive coil 410 and the second deflection drive magnet 420 are respectively disposed opposite to each other on the deflection member 200 and the mounting base 100. Different magnetic field forces are obtained by adjusting the magnitude and direction of the current applied to the second deflection drive coil 410, so as to drive the deflection member 200 to deflect in different amplitudes and directions.

[0085] The second deflection drive coil 410, as an active device, can be disposed on the deflection member 200 and connected to the module circuit of the camera module fixed on the deflection member 200. It can obtain a controlled loading current signal through its module circuit to communicate with the outside world, thereby simplifying the communication structure. Correspondingly, the second deflection drive magnet 420 is disposed on the mounting base 100. Thus, both the mounting base 100 and the second deflection drive magnet 420 on it are passive devices, and there is no need to consider electrical connection operations during assembly, thereby simplifying the assembly operation.

[0086] Alternatively, the second deflection drive coil 410 can be mounted on the mounting base 100 and independently connected to the control circuit of the image stabilization device to obtain a controlled loading current signal. Correspondingly, the second deflection drive magnet 420, as a passive device, is directly mounted on the deflection component 200. Thus, during assembly, no additional electrical connection processing is required between the deflection component 200 and the camera module on it and the image stabilization device, which can simplify the processing to a certain extent.

[0087] In some embodiments, the second deflection drive coil 410 can be configured as two sets of drive coils, namely a third drive coil 411 and a fourth drive coil 412. The third drive coil 411 and the fourth drive coil 412 can be symmetrically arranged on both sides of the axis of the second rotating shaft 220. Thus, by applying currents in opposite directions to the third drive coil 411 and the fourth drive coil 412, two forces driving the rotation of the second rotating shaft 220 of the deflector 200 can be applied to both sides, improving the uniformity of the force. This makes the magnitude of the forces acting on the first elastic support 510 and the first elastic clamping member 520 equal, thereby keeping the center of the deflector 200 stable. This ensures that the tilt-shift operation is only a change in angle, restricts movement in other directions, maintains the stability of the position and attitude of the deflector, and ensures the shooting quality.

[0088] In some embodiments, the first deflection drive magnet 320 and the second deflection drive magnet 420 can be disposed on the outer side wall of the deflecting member 200, opposite to the inner side wall of the mounting base 100; correspondingly, through holes can be formed on the first deflection drive magnet 320 and the second deflection drive magnet 420 for the first rotating shaft 210 and the second rotating shaft 220 to pass through. Thus, during assembly, the first deflection drive magnet 320 and the second deflection drive magnet 420 can be positioned and installed through the through holes, and fixed to the outer side wall of the deflecting member 200 by a dispensing process, achieving accurate positioning and fixation.

[0089] See Figure 5 , Figure 6 , Figure 8 and Figure 9In some embodiments, considering that during the deflection of the deflector 200 around the first rotating shaft 210 and the second rotating shaft 220 simultaneously, the first rotating shaft 210 and the second rotating shaft 220 will experience a resultant force from the deflector 200, and this resultant force will change in real time with the deflection process. Consequently, the forces acting on the first elastic support 510, the first elastic clamping member 520, the second elastic support 610, and the second elastic clamping member 620 will also change in real time. As a result, the stress deformation of the first elastic support 510, the first elastic clamping member 520, the second elastic support 610, and the second elastic clamping member 620 will change accordingly, causing a change in the deflection attitude and angle of the deflector 200. That is, the anti-shake angle compensation will have a certain degree of error.

[0090] Therefore, a deflectable deflector can be provided on the mounting base for corresponding installation of the first elastic support 510, the first elastic clamping member 520, the second elastic support 610 and the second elastic clamping member 620; thus, it can be divided into a first deflector 530 and a second deflector 630.

[0091] When the direction of the force exerted on the first elastic support member 510 and the first elastic clamping member 520 by the first rotating shaft 210 changes, it can be transmitted to the first deflection seat 530 through the first elastic support member 510 and the first elastic clamping member 520. The first deflection seat 530 can be deflected slightly to maintain the deformation posture of the first elastic support member 510 and the first elastic clamping member 520 and maintain the posture stability of the first rotating shaft 210.

[0092] Specifically, a first receiving groove 532 can be formed on the main body of the first deflection seat 530 to accommodate the first elastic support member 510 and the first elastic clamping member 520. The first rotating shaft embedding part 211 also extends into the first receiving groove 532. The opening of the first receiving groove 532 is slightly smaller than the first elastic support member 510 and the first elastic clamping member 520, just enough to allow them to deform and pass through. To a certain extent, this increases the difficulty of their removal and helps maintain the integrity of their functional structure.

[0093] Similarly, when the direction of the force from the second rotating shaft 220 on the second elastic support 610 and the second elastic clamping member 620 changes, it can be transmitted to the second deflection seat 630 through the second elastic support 610 and the second elastic clamping member 620. The second deflection seat 630 can deflect slightly to maintain the deformation posture of the second elastic support 610 and the second elastic clamping member 620 and maintain the posture stability of the second rotating shaft 220.

[0094] Specifically, a second receiving groove can be formed on the main body of the second deflection seat 630 to accommodate the second elastic support 610 and the second elastic clamping member 620, and the second rotating shaft embedding part 221 also extends into the second receiving groove. The opening of the second receiving groove is slightly smaller than that of the second elastic support 610 and the second elastic clamping member 620, ensuring that they can deform and pass through. To a certain extent, this increases the difficulty of their removal, making it easier to maintain the integrity of their functional structure.

[0095] See Figure 6 , Figure 8 , Figure 9 and Figure 13 In some embodiments, to achieve stable deflection of the first deflection seat 530 on the mounting base 100, a first deflection shaft 531 can be provided on the main body of the first deflection seat 530, and a corresponding deflection hole 120 can be provided on the mounting base 100. The first deflection shaft 531 can be rotatably disposed within the deflection hole 120. Furthermore, a lubricating coating can be provided on the deflection hole 120 or the first deflection shaft 531, or a self-lubricating material can be directly used for molding.

[0096] Similarly, the structure of the second deflector 630 can also be configured to be the same as that of the first deflector 530.

[0097] It is worth noting that the deflection hole 120 can be set in the mounting groove 110, and correspondingly, the first deflection seat 530 can be set in the mounting groove 110. Thus, the overall structure can be reduced in size by slotting installation, thereby reducing the required installation space to a certain extent.

[0098] See Figure 13In some embodiments, considering that the deflection displacements of different regions of the first deflection seat 530 body are inconsistent, the mounting groove 110 can be configured as a first cavity 111 and a second cavity 112 that are in communication. The first cavity 111 and the second cavity 112 can be configured as fan-shaped cavities that gradually widen from the area where they are connected to the area away from the area where they are connected. The deflection hole 120 is located at the center of the area where they are connected, so that the first cavity 111 and the second cavity 112 can meet the deflection requirements of the first deflection seat 530 and the second deflection seat 630.

[0099] In some embodiments, considering that when the deflector 200 deflects synchronously relative to the first rotating shaft 210 and the second rotating shaft 220, the force transmitted to the first elastic support 510, the first elastic clamping member 520, the second elastic support 610 and the second elastic clamping member 620 does not change direction in one plane, but is a component that also acts along the axial direction of the first rotating shaft 210 or the second rotating shaft 220, however, when the first deflector shaft 531 rotates within the deflection hole 120, the first rotating shaft 531 will be limited on the radial side and cannot deflect along the actual force. Correspondingly, the deformation posture of the first elastic support 510, the first elastic clamping member 520, the second elastic support 610 and the second elastic clamping member 620 will have a small-amplitude random deformation, resulting in an uneven overall deflection posture and uneven position change of the deflector 200.

[0100] Therefore, the first deflection shaft 531 can be configured as a ball joint. By utilizing the characteristic that the ball joint can deflect along a spherical surface, it can well adapt to the deflection posture changes of the deflection member and maintain the stability of the deformation shape of the first elastic support member 510 and the first elastic clamping member 520.

[0101] Correspondingly, a ball bearing is also provided on the mounting base 100 to match and fix the ball head rod.

[0102] See Figure 14 Generally, the mounting base 100 is provided with an outer shell 130 to achieve overall protection and isolate debris.

[0103] In some embodiments, the first elastic support 510, the first elastic clamping member 520, the second elastic support 610 and the second elastic clamping member 620 are elastic elements such as springs that can achieve linear deformation within a certain range; they can also be made of elastic rubber or other elements with stable deformation capabilities.

[0104] In some embodiments, an optical image stabilization camera module based on the above-described image stabilization device is provided. The camera module can be mounted on the deflector 200, or the deflector 200 can be shaped to serve as the housing of the camera module.

[0105] In some embodiments, an electronic device is also provided, including the aforementioned optical image stabilization camera module.

[0106] The embodiments of this application have at least the following beneficial effects:

[0107] The image stabilization device, optical image stabilization camera module, and electronic device provided in this application embodiment have two perpendicular first and second rotating shafts on a deflector. An elastic support is provided on a mounting base corresponding to each end of the first and second rotating shafts to abut and support the first and second rotating shafts. An elastic clamping member is also provided on each shaft to clamp the ends of the first and second rotating shafts respectively, thereby allowing both ends of the first and second rotating shafts to elastically shift and reset under external force. This enables the deflector to... The device can independently perform deflection operations around the first and second rotating axes, and can also simultaneously perform deflection operations of the deflecting element around the first and second rotating axes respectively. Specifically, when the deflecting element is driven to deflect around the first rotating axis by the first deflection drive assembly, an elastic support member and an elastic clamping member are respectively pressed against both ends of the first rotating axis. The elastic support member and the elastic clamping member at both ends of the first rotating axis basically maintain their current shape, similar to the rigid rotation support structure of a conventional gimbal bracket. However, in this embodiment, the second deflection drive assembly can also be used simultaneously. The component drives the deflector to deflect around the second axis. At this time, both ends of the first axis press against another elastic support and another elastic clamping member, respectively, achieving elastic displacement and obtaining sufficient deflection space to complete the deflection operation around the second axis. However, the rigid rotational support structure of the conventional gimbal bracket lacks deflection space and cannot implement deflection, thus requiring the deflection on the two axes to be decomposed into two independent brackets. Therefore, this application obtains four elastic support structures by setting elastic support and elastic clamping member groups at both ends of the mutually perpendicular first and second axes, thereby achieving... Within a single bracket structure, the deflector can rotate around two vertical axes. This simplifies the structural complexity and size of the camera module after it is mounted on the deflector, making it more suitable for installation in a wider range of products with less installation space while achieving a larger stabilization angle, thus expanding its application scope. On the other hand, by utilizing the linear deformation characteristics of the elastic element, the deflection attitude change of the deflector can be achieved linearly and smoothly, avoiding the impact of instantaneous vibration during the deflection adjustment process on the shooting quality. Therefore, it can balance the stabilization effect and the shooting quality to a certain extent.
