Abstract
Description
Technical Field
[0001] The embodiments of the present invention relate to the field of optical technology, and in particular to an imaging device and a camera. Background Art
[0002] With the rapid development of photographic technology, camera devices containing lens driving devices are applied to various portable electronic devices, especially mobile phones, tablet computers, etc., and are widely accepted by consumers.
[0003] The lens driving device equipped in a portable electronic device usually includes a focusing mechanism for adjusting the focus in the direction of the optical axis and an anti-vibration mechanism for adjusting the lens in a plane orthogonal to the optical axis. The two are usually designed as one piece and are realized by electromagnetic drive of coils and magnets. Usually, the coil is fixed on the periphery of the lens bracket. When the coil is energized and subjected to the magnetic force of the magnet, the lens bracket fixed with the coil can drive the lens to move along the optical axis of the lens under the action of the magnetic force to achieve focusing; when the user holds the portable electronic device to take pictures, the lens shake caused by hand shaking can be corrected by the lens bracket driving the lens to move in a direction perpendicular to the optical axis.
[0004] Since the focusing mechanism and the anti-vibration mechanism are integrated, it is necessary to suppress the inherent vibration of the two mechanisms and consider the centering adjustment of the lens during assembly, which makes the assembly difficult. In addition, since the focusing mechanism and the anti-vibration mechanism can drive the lens to move in three dimensions, this inevitably brings about the problem of drop impact. Since the anti-vibration mechanism usually does not work during drop impact, the entire mechanism is easily worn or indented after the impact, which in turn causes damage to the anti-shake function.
[0005] Therefore, it is necessary to provide a camera device and a camera to solve the above problems. Summary of the invention
[0006] The purpose of the embodiments of the present invention is to provide a camera device and a camera to reduce the difficulty of assembly and avoid damage to the anti-shake function due to wear and indentation caused by falling and impact.
[0007] In order to solve the above technical problems, the present invention provides a camera device, comprising an autofocus lens module with an optical axis, an imaging module that cooperates with the autofocus lens module to form an image, and an anti-vibration mechanism to prevent vibration; the anti-vibration mechanism comprises, from the image side to the object side, a base, on which a magnet is arranged; a drive frame, rotatably arranged on the base, the rotation axis of the drive frame being perpendicular to the optical axis, the drive frame being provided with a locking mechanism and a locking yoke located on one side of the rotation axis, and a driving coil located on the other side of the rotation axis; a movable frame, on which the imaging module is fixedly arranged, The movable frame drives the imaging module to move relative to the optical axis to achieve anti-shake, and the movable frame is provided with a matching mechanism opposite to the locking mechanism; when the driving coil is not energized, the magnet attracts the locking yoke to press the driving frame on the base, and the locking mechanism and the matching mechanism approach and cooperate with each other to lock the movable frame and the driving frame together; after the driving coil is energized to generate a magnetic field, the magnet drives the driving frame to rotate via the driving coil, so that the locking mechanism and the matching mechanism move away from each other and release the matching, so as to release the lock of the movable frame and the driving frame.
[0008] In some embodiments, the locking mechanism is a locking hole, and the mating mechanism is a locking pin. The locking pin approaches and extends into the locking hole to achieve mating and lock the movable frame and the driving frame together, and the locking pin withdraws and moves away from the locking hole to release the mating and release the lock of the movable frame and the driving frame.
[0009] In some embodiments, the locking mechanism is a locking pin, and the mating mechanism is a locking hole. The locking pin approaches and extends into the locking hole to achieve mating and lock the movable frame and the driving frame together, and the locking pin withdraws and moves away from the locking hole to release the mating and release the lock of the movable frame and the driving frame.
[0010] In some embodiments, the distal end portion is provided with an installation space recessed from the image side toward the object side, the opening of the installation space faces one side of the base and accommodates the driving coil therein; the proximal end portion is provided with a receiving space recessed from the object side toward the image side, the receiving space faces one side of the movable frame and accommodates the locking yoke.
[0011] In some embodiments, there are two or more locking pins.
[0012] In some embodiments, the two or more locking pins are arranged in sequence and spaced apart from each other in an edge area of the proximal portion close to the optical axis in a direction parallel to the rotation axis, and the locking pins extend from the proximal portion in a direction parallel to the optical axis toward the movable frame and extend into the locking hole.
[0013] In some embodiments, a support rod is protruded from the base toward the driving frame in a direction parallel to the optical axis, and the driving frame is rotatably disposed at the protruding end of the support rod.
[0014] In some embodiments, a receiving groove corresponding to the support rod is provided on the driving frame, the protruding end of the support rod extends into the receiving groove and supports the driving frame, and the driving frame is rotatably provided on the base around the protruding end of the support rod.
[0015] In some embodiments, the protruding end of the support rod is a spherical convex surface, and the bottom surface of the receiving groove is a spherical concave surface.
[0016] The present invention also provides a camera, comprising an aperture mechanism and the above-mentioned camera device.
[0017] The beneficial effects of the present invention are as follows: a relative driving coil and a locking mechanism are respectively arranged on the rotatable driving frame, and a matching mechanism that matches the locking mechanism is arranged on the movable frame fixed with the imaging module, so that when the driving coil is in a non-powered working state, the magnet generates an attractive force on the locking yoke, so that the driving frame is pressed on the base, and the locking mechanism and the matching mechanism are close to each other and matched to lock the movable frame and the driving frame together; when the driving coil is in a powered working state, the magnet generates an electromagnetic force on the driving coil to drive the driving frame to rotate, and the locking mechanism and the matching mechanism are separated from each other and released from the matching to release the locking of the movable frame and the driving frame. In this way, the locking and contact of the movable frame and the driving frame can be achieved by whether the driving coil is powered or not, which is not only convenient for suppressing the inherent vibration of the anti-shake structure during the assembly process, thereby reducing the difficulty of design and assembly, but also can prevent the entire mechanism from being impacted and causing wear and indentation through the locking of the movable frame and the driving frame during the drop impact, thereby preventing the anti-shake function from being damaged.

[0078] The implementation details of the imaging device, camera and electronic device provided by the present invention are specifically described below. The following content is only provided for the convenience of understanding the implementation details and is not necessary for implementing the present solution.
[0079] A first embodiment of the present invention relates to a camera device, such as Figure 1 to Figure 2As shown, it includes: an auto-focus lens module 100 with an optical axis OO', an imaging module 200 for imaging with the auto-focus lens module 100, and an anti-vibration mechanism 300 for preventing vibration; the anti-vibration mechanism 300 includes, from the image side to the object side, a base 31; a magnet 32 arranged on the base 31; a driving frame 33, rotatably arranged on the base 31, and the rotation axis of the driving frame 33 is perpendicular to the optical axis OO', please refer to Figure 3 and Figure 4 The driving frame 33 is provided with a locking driving coil 331 located on one side of the rotation axis, a locking yoke 341 and a locking mechanism 332 located on the other side of the rotation axis; the movable frame 34, the imaging module 200 is fixedly arranged on the movable frame 34, the movable frame 34 drives the imaging module 200 to move together with the optical axis OO' to achieve anti-shake, and the movable frame 34 is provided with a matching mechanism 342 opposite to the locking mechanism 332; when the locking driving coil 331 is not energized, the magnet 32 The locking yoke 341 is attracted to press the driving frame 33 onto the base 31, and the locking mechanism 332 and the matching mechanism 342 are brought close to and matched with each other, so as to lock the movable frame 34 and the driving frame 33 together; after the locking driving coil 331 is energized to generate a magnetic field, the magnet 32 drives the driving frame 33 to rotate via the locking driving coil 331, so that the locking mechanism 332 and the matching mechanism 342 are moved away from each other and released from matching, so as to release the lock of the movable frame 34 and the driving frame 33.
[0080] Compared with the prior art, the embodiment of the present invention respectively provides a relative locking drive coil 331 and a locking mechanism 332 on the rotatable driving frame 33, and provides a matching mechanism 342 matching with the locking mechanism on the movable frame 34 fixed with the imaging module 200, so that when the locking drive coil 331 is in a non-energized working state, the magnet 32 generates an attractive force on the locking yoke 341, so that the driving frame 33 is pressed on the base 31, and the locking mechanism 332 and the matching mechanism 342 approach and match with each other to lock the movable frame 34 and the driving frame 33 together; when the locking drive coil 331 is in a energized working state, the magnet 32 generates an electromagnetic force on the locking drive coil 331 to drive the driving frame 33 to rotate, and the locking mechanism 332 and the matching mechanism 342 move away from each other and release the matching, so as to release the locking of the movable frame 34 and the driving frame 33. In this way, the locking and contact of the movable frame 34 and the driving frame 33 can be achieved simply by locking whether the driving coil 331 is energized. This not only makes it easier to suppress the inherent vibration of the anti-shake structure during assembly, thereby reducing the difficulty of design and assembly, but also prevents the entire mechanism from being impacted and causing wear and indentation by locking the movable frame 34 and the driving frame 33 during a fall impact, thereby preventing the anti-shake function from being damaged.
[0081] Specifically, the auto-focus lens module 100 includes a first housing 10A, a base 10B, a lens 11, a lens bracket 12, an upper leaf spring 13, a lower leaf spring 14, an auto-focus driving coil 15, and a driving magnet 16. Figure 2 shown.
[0082] The first shell 10A and the base 10B together enclose a receiving space to receive other components of the autofocus lens module 100. The lens 11 has an optical axis OO', which is used to converge light for imaging by the imaging module 200. The lens bracket 12 is arranged in the shell 10, and is used to carry and fix the lens 11. The lens bracket 12 is fixed to the first shell 10A and the base 10B via an upper leaf spring 13 and a lower leaf spring 14, respectively, and is movable in the direction of the optical axis OO', so that the upper leaf spring 13 and the lower leaf spring 14 are used to make the lens bracket 12 keep the lens 11 in a hollow position without being affected by electromagnetic force. An autofocus drive coil 15 is wound on the lens bracket 12, and a drive magnet 16 is arranged on the base 10B, so that when the autofocus drive coil 15 is energized, the magnetic force generated by the drive magnet 16 on the autofocus drive coil 15 can drive the lens bracket 12 to drive the lens 11 to move in the direction of the optical axis OO', thereby realizing autofocus.
[0083] It can be understood that in order to power on and off the autofocus drive coil 15 to control autofocus, the autofocus lens module 100 also includes a flexible circuit board 17. The autofocus drive coil 15 is connected to a servo control device (which can be arranged on the first flexible circuit board 17) via the first flexible circuit board 17, so that autofocus can be achieved by powering on and off under the control of the servo control device.
[0084] Preferably, in order to detect the position of the lens 11 during the autofocus process, the autofocus lens module 100 further includes a position detection element 18A and a position detection magnet 18B. Specifically, the position detection element 18A is disposed on the first flexible circuit board 17, and the position detection magnet 18B is disposed on the lens bracket 12, so that the position detection element 18A can detect the magnetic flux of the position detection magnet 18B to determine the precise position of the lens bracket 12, and then send it to the servo control device to realize the position detection function of the lens 11.
[0085] In addition, in a feasible embodiment, the lens holder 12 may also be coated with a first anti-vibration gel 19, which can buffer and control the vibration effect of the lens holder 12 when the autofocus drive coil 15 is suddenly energized, thereby playing a shock-absorbing role and achieving a more accurate autofocus function.
[0086] The imaging module 200 may be an image sensor, and the light beam of the subject passing through the lens 1 along the optical axis OO′ converges on the imaging module 200 to form an image.
[0087] The anti-vibration mechanism 300 includes a base 31 , a magnet 32 , a driving frame 33 , and a movable frame 34 , which are arranged in this order from the image side to the object side.
[0088] The base 31 is used to carry the magnet 32 so as to apply magnetic force to the driving frame 33 and the movable frame 34 through the magnet 32. Preferably, the anti-vibration mechanism 300 further includes a second shell 35 buckled on the image side of the base 10B, so that the second shell 35 and the base 10B together enclose a space for accommodating the base 31, the magnet 32, the driving frame 33 and the movable frame 34, the base 31 is arranged on the second shell 35, and the support plate 370 is fixedly arranged on the base 31.
[0089] The drive frame 33 is rotatably disposed on the base 31, the rotation axis of the drive frame 33 is perpendicular to the optical axis OO', and the drive frame 33 is provided with a locking drive coil 331 and a locking mechanism 332 located on opposite sides of the rotation axis. Preferably, the base 31 protrudes toward the drive frame 33 in a direction parallel to the optical axis OO'. Figure 4 The support rod 310 shown in the figure, the driving frame 33 is rotatably arranged on the protruding end of the support rod 310, for example, the driving frame 33 can be pivotally connected to the protruding end of the support rod 310 (that is, Figure 4 The top of the support rod 310 shown in the figure). More preferably, in one embodiment, the drive frame 33 is provided with a receiving groove 330 corresponding to the support rod 310, the protruding end of the support rod 310 extends into the receiving groove 330 and supports the drive frame 33, and the drive frame 33 is rotatably arranged on the base 31 around the protruding end of the support rod 310. Further, the end of the support rod 310 can be designed as a spherical convex surface, and correspondingly, the bottom surface of the receiving groove 330 is a spherical concave surface, so that the resistance to the rotation of the drive frame 33 can be reduced, and a better rotation effect can be achieved.
[0090] Please also see Figure 5 , Figure 6 and Figure 7 Further, the driving frame 33 may include a proximal end portion 333 adjacent to the optical axis OO' and a distal end portion 334 away from the optical axis OO', the distal end portion 334 is provided with an installation space 3340 recessed from the image side toward the object side, the opening of the installation space 3340 faces one side of the base 31 and accommodates the locking driving coil 331 therein; the proximal end portion 333 is provided with a receiving space 3330 recessed from the object side toward the image side, the receiving space 3330 faces one side of the movable frame 34 and accommodates a locking yoke 341, the locking driving coil 331 and the locking yoke 341 are located on the same side of the support rod 310 (that is, in the direction perpendicular to the optical axis OO', the locking driving coil 331 is farthest from the optical axis OO', the support rod 310 is closest to the optical axis OO', and the locking yoke 341 is located between the locking driving coil 331 and the support rod 310). Figure 7 (a) shows a schematic diagram of a local structure in which the driving frame 33 does not rotate. Figure 7 (b) shows that the drive frame 33 is attracted by the magnet 32 to lock the drive coil 331, causing the drive frame 33 to rotate along the axis of rotation ( Figure 7 Schematic diagram of the local structure of the counterclockwise rotation (shown by the dotted line in (b), Figure 7 (c) shows that the drive frame 33 is repelled by the magnet 32 and the locking drive coil 331, causing the drive frame 33 to rotate along the axis of rotation ( Figure 7 Schematic diagram of the local structure rotating in the clockwise direction (shown by the dotted line in (c)).
[0091] When the locking coil 331 is not energized, the magnet 32 will not exert magnetic force on the locking coil 331, but will attract the locking yoke 341, so that the distal end 334 of the driving frame 33 is subjected to a downward force and pressed down toward the magnet 32, and the proximal end 333 of the driving frame 33 rises under the action of the lever, thereby driving the locking mechanism 332 to approach the matching mechanism 342 to achieve locking, and keeping Figure 7 (b) The state shown.
[0092] When the locking coil 331 is energized, the magnet 32 exerts an upward repulsive force on the energized locking coil 331, and the repulsive force overcomes the attractive force exerted by the magnet 32 on the locking yoke 341, so that the distal end 334 is subjected to an upward force and rises upward away from the magnet 32, and the proximal end 333 of the driving frame 33 is pressed downward under the action of the lever, thereby driving the locking mechanism 332 to move away from the matching mechanism 342 and reach the Figure 7 (a) and finally arrive at Figure 7 (c) shows the state to achieve unlocking.
[0093] In this way, the driving frame 33 is driven to rotate by controlling the power supply of the locking driving coil 331 to drive the locking mechanism 332 away from the matching mechanism 342 to achieve unlocking.
[0094] Please see again Figure 2 The movable frame 34 is used to carry and fix the imaging module 200, and the anti-vibration mechanism 300 also includes a driving module 36 that drives the movable frame 34 to move in an orthogonal plane perpendicular to the optical axis OO' and tilt relative to the optical axis OO' to achieve anti-shake. In a feasible embodiment, the driving module 36 includes a driving substrate 360, an anti-vibration coil 361 disposed on the driving substrate 360, a position detection element 362 disposed on the driving substrate 360, and a bearing plate 363 fixed on the movable frame 34 together with the driving substrate 360. Thus, the movable frame 34 fixed with the imaging module 200 and the bearing plate 363 is supported by the supporting component 37 and arranged on the supporting plate 370, so that the supporting component 37 can rotate under the action of external force, so that the bearing plate 363 and the supporting plate 370 located on both sides of the supporting component 37 can rotate relative to each other, and then the anti-vibration coil 361 on the driving substrate 360 can drive the movable frame 34 to move freely in an orthogonal plane perpendicular to the optical axis OO' to achieve anti-vibration when it is energized and subjected to the magnetic force of the magnet 32. Correspondingly, the position detection element 362 on the driving substrate 360 detects the magnetic flux of the magnet 32 to perform correct position detection and anti-vibration control. It can be understood that the surface accuracy of the bearing plate 363 and the supporting plate 370 can be ensured during the design and manufacturing process to ensure that the supporting component 37 can rotate smoothly.
[0095] It is understandable that the anti-vibration coil 361 can be a plurality of single coil windings, or a conductive pattern formed on the drive substrate 360. In a feasible embodiment, the drive substrate 360 is a flexible substrate. In a feasible implementation, the two anti-vibration coils 361 on each side of the drive substrate 360 can apply currents in opposite directions, so that the movable frame 34 rotates relative to the optical axis OO', preventing the rotational deviation of the lens 11, and realizing automatic focusing and anti-vibration of four axes.
[0096] Preferably, in a feasible implementation, the anti-vibration coil 361, the position detection element 362, the signal line and the power line of the imaging module 200 can be electrically connected through the second flexible circuit board 38 located outside the anti-vibration mechanism 300 to avoid affecting the movement of the anti-vibration mechanism 300. Further, the second flexible circuit board 38 is provided with a curved surface located in the space between the second shell 35 and the first shell 10A, thereby forming a structure that avoids hindering the movement of the anti-vibration mechanism 300. It should be noted that the first flexible circuit board 17 of the auto-focus lens module 100 can also be arranged on the outside of the auto-focus lens module 100, so as to be connected to the second flexible circuit board 38 of the anti-vibration mechanism 300. In this way, the first flexible circuit board 17 for auto-focusing can be integrated with the second flexible circuit board 38 for anti-shake.
[0097] The movable frame 34 is provided with an anti-vibration yoke 340 and a matching mechanism 342 opposite to the locking mechanism 332. In a feasible embodiment, the magnet 32 can attract the anti-vibration yoke 340 toward the optical axis OO' (that is, the center of the orthogonal plane) in the orthogonal plane of the optical axis OO', and can attract the anti-vibration yoke 340 in the direction along the optical axis OO', thereby achieving the effect of a magnetic spring and effectively reducing the inclination of the imaging module 200 relative to the optical axis OO'. In addition, the presence of the anti-vibration yoke 340 presses the movable frame 34 on the driving frame 33 through the attraction of the magnet 32, so that the bearing plate 363 and the support plate 370 can clamp the support component 37, prevent the support component 37 from falling off, and avoid magnetic leakage.
[0098] When the locking drive coil 331 is not energized, the magnet 32 attracts the locking yoke 341 to hold the drive frame 33 on the base 31, and the locking mechanism 332 and the matching mechanism 342 are close to each other and matched, so as to lock the movable frame 34 and the drive frame 33 together. In this state, the movable frame 34 is located so that the optical axis OO' passes through the center of the imaging module 200.
[0099] After the locking drive coil 331 is energized to generate a magnetic field, the magnet 32 drives the drive frame 33 to rotate via the locking drive coil 331, so that the locking mechanism 332 and the matching mechanism 342 move away from each other and release the matching, thereby releasing the lock of the movable frame 34 and the drive frame 33.
[0100] Specifically, in a feasible embodiment, the locking mechanism 332 is a locking pin, and the matching mechanism 342 is a locking hole. The locking pin approaches and extends into the locking hole to achieve matching and lock the movable frame 34 and the driving frame 33 together, and the locking pin withdraws and moves away from the locking hole to release the matching and release the lock of the movable frame 34 and the driving frame 33.
[0101] More specifically, when the unlocking operation is implemented, the power supply of the locking drive coil 331 can be controlled so that the magnet 32 exerts an upward repulsive force on the energized locking drive coil 331, thereby driving the drive frame 33 to support the end of the rod 310 (i.e. Figure 4 The top of the support rod 310 is shown in the figure and rotates as the center (the rotation axis is a straight line perpendicular to the drawing / paper surface and passing through the end of the support rod 310), so that the distal end 334 of the drive frame 33 moves upward and the proximal end 333 moves downward, so that the locking pin located at the proximal end 333 is away from the locking hole and the drive frame 33 and the movable frame 34 are unlocked. In this way, when the anti-vibration mechanism 300 is not in operation, if it falls and causes external impact, the camera device can obtain information through components such as gyroscopes as posture and acceleration detection elements, and then lock the drive frame 33 and the movable frame 34 at the moment of falling, protect the anti-vibration mechanism 300 from impact, and avoid wear and indentation caused by falling impact, which may cause damage to the anti-shake function. In addition, in the process of assembling the camera device, the locking of the drive frame 33 and the movable frame 34 can also be used to achieve centering without the need for large-scale clamps, thereby reducing the difficulty of assembly.
[0102] It can be understood that the specific forms of the locking mechanism 332 and the matching mechanism 342 can also be interchanged, and the locking mechanism 332 is set as a locking hole, while the matching mechanism 342 is set as a locking pin. In addition, the number of locking pins can be one, two or more. Preferably, there are more than two locking pins. In a feasible embodiment, more than two locking pins are arranged in sequence at intervals from each other in a direction parallel to the rotation axis of the driving frame 33 at the edge area of the proximal portion 333 close to the optical axis OO', and each locking pin extends from the proximal portion 333 toward the movable frame 34 in a direction parallel to the optical axis OO' and extends into the locking hole.
[0103] Preferably, in a feasible implementation, the anti-vibration mechanism 300 further includes a second anti-vibration gel 39 disposed between the movable component and the fixed component, and the second anti-vibration gel 39 can buffer and control the vibration effect of the movable frame 34 when the anti-vibration coil 361 is suddenly energized, thereby playing a shock-absorbing role and achieving a more accurate anti-vibration function. Of course, the second anti-vibration gel 39 can also be replaced by an adhesive such as lubricating oil or a dust collector.
[0104] It should be noted that the imaging module 200 may include an image sensor and an infrared cutoff filter. The movable frame 34 forms an integrated structure with the imaging module 200. When used in conjunction with the driving frame 33 to realize the locking and unlocking functions to improve the structural rigidity and enhance the drop protection, it can also reduce the number of components of the imaging module 200 and improve the verticality of the imaging module 200 compared to the optical axis OO' to avoid tilting, which is beneficial to miniaturization and low-profile design, and improves both assembly and anti-vibration performance.
[0105] The embodiment of the present invention relates to a camera system, including the camera device of the above embodiment, and the camera system may have a sunken zoom mechanism or a periscope optical path structure.

[0106] Compared with the prior art, the camera device of the above-mentioned embodiment is arranged on the periscope optical mechanism 400, and the movable frame and the driving frame can be locked and contacted by the power supply of the driving coil. This not only makes it easy to suppress the inherent vibration of the anti-shake structure during the assembly process, thereby reducing the difficulty of design and assembly, but also can prevent the entire mechanism from being impacted and causing wear and indentation by locking the movable frame and the driving frame during a drop impact, thereby avoiding damage to the anti-shake function.
[0107] An embodiment of the present invention also relates to a camera, such as Fig. 9 As shown, it includes: an aperture mechanism 500 and the camera device of the above embodiment.
[0108] Compared with the prior art, the camera device of the above-mentioned embodiment that is arranged in the camera and cooperates with the aperture mechanism 500 can also achieve the locking and contact of the movable frame and the driving frame by controlling whether the driving coil is energized or not. This not only makes it easy to suppress the inherent vibration of the anti-shake structure during the assembly process, thereby reducing the difficulty of design and assembly, but also can prevent the entire mechanism from being impacted and causing wear and indentation by locking the movable frame and the driving frame during a drop impact, thereby preventing the anti-shake function from being damaged.
[0109] It is understandable that the aforementioned camera device, camera system and camera can be applied to various electronic devices with shooting functions, such electronic devices can be portable terminals such as mobile phones, tablet computers, smart watches, or laptop computers or other terminals.
[0110] The embodiment of the present invention also relates to an electronic device with a shooting function, such as Fig.10 As shown, it includes: a device body 600 and the camera device of the above embodiment arranged on the device body.
[0111] As for the prior art, the camera device of the above-mentioned embodiment is arranged on an electronic device, and the movable frame and the driving frame can be locked and contacted by the power supply of the driving coil. This not only makes it easy to suppress the inherent vibration of the anti-shake structure during the assembly process, thereby reducing the difficulty of design and assembly, but also can prevent the entire mechanism from being impacted and causing wear and indentation by locking the movable frame and the driving frame during a drop impact, thereby preventing the anti-shake function from being damaged.
