Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE Embodiments of the present invention relate to the field of optical technology, and in particular to imaging devices and cameras. [Background technology]

[0002] 2. Description of the Related Art With the rapid development of photography technology, imaging devices including lens driving devices are applied to various portable electronic devices, and in particular, mobile phones, tablets, etc. are widely accepted by consumers.

[0003] A lens driving device mounted on a portable electronic device usually includes a focus mechanism for adjusting the focus in the optical axis direction and an anti-vibration mechanism for adjusting the lens in a plane perpendicular to the optical axis, and the two are usually designed as one unit and are realized by electromagnetic driving of a coil and a magnet. In general, the coil is fixed to the outer periphery of the lens carrier, and when the coil is energized and subjected to the magnetic force of the magnet, the lens carrier to which the coil is fixed can be driven by the magnetic force to move the lens along the optical axis direction of the lens to achieve focusing. When a user takes a picture while holding the portable electronic device in his / her hand, the lens shake caused by the hand shake can be corrected by moving the lens along the direction perpendicular to the optical axis by the lens carrier.

[0004] Because the focus mechanism and anti-vibration mechanism are integrated, it is necessary to suppress the inherent vibrations of the two mechanisms and consider the centering adjustment of the lens during assembly, which makes the assembly more difficult. In addition, because the focus mechanism and anti-vibration mechanism can move the lens three-dimensionally, the problem of drop impact is unavoidable. When dropped and impacted, the anti-vibration mechanism does not operate normally, so the entire mechanism is subjected to impact, making it prone to wear and indentations, which impairs the image stabilization function.

[0005] Therefore, there is a need to provide an imaging device and camera that solves the above problems. Summary of the Invention [Problem to be solved by the invention]

[0007] In order to solve the above technical problems, the present invention provides an imaging device, the imaging device including an autofocus lens module having an optical axis, an imaging module that cooperates with the autofocus lens module to form an image, and an anti-vibration mechanism that prevents vibration, the anti-vibration mechanism including, in order from the image side to the object side, a base on which a magnet is provided, a drive frame rotatably provided on the base, and a movable frame, the rotation axis of the drive frame is perpendicular to the optical axis, the drive frame is provided with a lock drive coil located on one side of the rotation axis, and a lock yoke and lock mechanism located on the other side of the rotation axis, the imaging module is fixed to the movable frame, and a hand shake compensation mechanism is provided. When no current is applied to the lock drive coil, the magnet attracts the lock yoke to press and hold the drive frame against the base so as to lock the movable frame and the drive frame together, and the lock mechanism and the fitting mechanism approach each other and fit together. After current is applied to the lock drive coil to generate a magnetic field, the magnet drives the drive frame to rotate by the lock drive coil so as to release the lock between the movable frame and the drive frame, and the lock mechanism and the fitting mechanism are separated from each other to release the fitting.

[0008] In some embodiments, the locking mechanism is a locking hole and the mating mechanism is a locking pin, where the locking pin approaches and inserts into the locking hole to achieve mating and lock the movable frame and the drive frame together, and the locking pin moves out of the locking hole to release the mating and unlock the movable frame and the drive frame.

[0009] In some embodiments, the locking mechanism is a locking pin and the mating mechanism is a locking hole, where the locking pin approaches and inserts into the locking hole to achieve mating and lock the movable frame and the drive frame together, and where the locking pin moves out of and away from the locking hole to release mating and unlock the movable frame and the drive frame.

[0010] In some embodiments, the drive frame includes a proximal portion close to the optical axis and a distal portion away from the optical axis, the distal portion being provided with a mounting space recessed from the image side toward the object side, an opening of the mounting space facing the base side and housing the lock drive coil therein, and the proximal portion being provided with an accommodation space recessed from the object side toward the image side, the accommodation space facing the movable frame side and housing the lock yoke.

[0011] In some embodiments, the number of locking pins is two.

[0012] In some embodiments, the two locking pins are arranged sequentially at intervals from each other in an edge region close to the optical axis of the proximal part along a direction parallel to the rotation axis, and the locking pin extends from the proximal part to the movable frame along a direction parallel to the optical axis and is inserted into the locking hole.

[0013] In some embodiments, a support rod protrudes from the base in a direction parallel to the optical axis toward a drive frame, and the drive frame is rotatably mounted on the protruding end of the support rod.

[0014] In some embodiments, the drive frame has an accommodating groove corresponding to the support rod, the protruding end of the support rod extends into the accommodating groove to support the drive frame, and the drive frame is rotatably mounted 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 further provides a camera including a camera body and the above-described imaging device. Effect of the Invention

[0017] The beneficial effect of the present invention is that a lock drive coil and a lock mechanism facing each other are provided on a rotatable drive frame, and an engagement mechanism that engages with the lock mechanism is provided on a movable frame to which an imaging module is fixed, and in an operating state in which no current is applied to the lock drive coil, a magnet generates an attractive force against the lock yoke to press and hold the drive frame against the base, and the lock mechanism and the engagement mechanism approach each other and engage, thereby locking the movable frame and the drive frame together. In an operating state in which current is applied to the lock drive coil, a magnet generates an electromagnetic force against the lock drive coil to drive the drive frame to rotate, and the lock mechanism and the engagement mechanism move away from each other to release the engagement, thereby unlocking the movable frame and the drive frame. This makes it possible to lock and contact the movable frame and drive frame simply by whether or not electricity is flowing through the lock drive coil, which suppresses the inherent vibration of the image stabilization structure during assembly and makes it easy to reduce the difficulty of design and assembly.In addition, by locking the movable frame and drive frame in the event of a drop impact, the entire mechanism is prevented from being subjected to impact, which would cause wear and indentations, and impair the image stabilization function.

[0025] The following is a detailed description of the implementation of the imaging device, camera, and electronic device according to the present invention. The following content is provided only to facilitate understanding of the implementation details, and is not essential for implementing the present invention.

[0026] As shown in FIG. 1 and FIG. 2, an imaging device in a first embodiment of the present invention includes an autofocus lens module 100 having an optical axis OO', an imaging module 200 that cooperates with the autofocus lens module 100 to form an image, and an anti-vibration mechanism 300 that prevents vibration. The anti-vibration mechanism 300 includes, in order from the image side to the object side, a base 31 on which a magnet 32 ​​is provided, a drive frame 33, and a movable frame 34. The drive frame 33 is rotatably provided on the base 31, and the rotation axis of the drive frame 33 is perpendicular to the optical axis OO'. Referring to FIG. 3 and FIG. 4 together, the drive frame 33 is provided with a lock drive coil 331 located on one side of the rotation axis, and a lock yoke 341 and a lock mechanism 332 located on the other side of the rotation axis. The imaging module 200 is fixed to the movable frame 34. When the lock drive coil 331 is not energized, the magnet 32 ​​attracts the lock yoke 341 to press and hold the drive frame 33 against the base 31 so as to lock the movable frame 34 and the drive frame 33 together, and the lock mechanism 332 and the engagement mechanism 342 approach each other and engage with each other, and after energization is applied to the lock drive coil 331 to generate a magnetic field, the magnet 32 ​​drives the drive frame 33 to rotate by the lock drive coil 331 so as to release the lock between the movable frame 34 and the drive frame 33, and the lock mechanism 332 and the engagement mechanism 342 are separated from each other to release the engagement.

[0027] Compared with the prior art, in the embodiment of the present invention, the opposing lock drive coil 331 and the lock mechanism 332 are respectively provided on the rotatable drive frame 33, and the fitting mechanism 342 that fits with the lock mechanism is provided on the movable frame 34 to which the imaging module 200 is fixed, and in an operating state in which the lock drive coil 331 is not energized, the magnet 32 ​​generates an attractive force against the lock yoke 341 to press and hold the drive frame 33 against the base 31, and the lock mechanism 332 and the fitting mechanism 342 approach each other and fit together, thereby locking the movable frame 34 and the drive frame 33 together. In an operating state in which the lock drive coil 331 is energized, the magnet 32 ​​generates an electromagnetic force against the lock drive coil 331 to drive the drive frame 33 to rotate, and the lock mechanism 332 and the fitting mechanism 342 move away from each other to release the fitting, thereby unlocking the movable frame 34 and the drive frame 33. As a result, the locking and contact of the movable frame 34 and the drive frame 33 can be achieved simply by whether or not current is passed through the lock drive coil 331, which makes it easier to suppress the inherent vibration of the image stabilization structure during assembly and reduce the difficulty of design and assembly. In addition, by locking the movable frame 34 and the drive frame 33 in the event of a drop impact, the entire mechanism is prevented from being subjected to impact, which would cause wear and indentations, and impair the image stabilization function.

[0028] Specifically, as shown in FIG. 2, the autofocus lens module 100 includes a first case 10A, a base 10B, a lens 11, a lens carrier 12, an upper leaf spring 13, a lower leaf spring 14, an autofocus drive coil 15, and a drive magnet 16.

[0029] The first case 10A and the base 10B together surround and form an accommodation space for accommodating other components of the autofocus lens module 100. The lens 11 has an optical axis OO', and collects light rays to provide imaging for the imaging module 200. The lens carrier 12 is provided in the first case 10A and is used to mount and fix the lens 11. The lens carrier 12 is fixed to the first case 10A and the base 10B by 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 lens carrier 12 maintains the lens 11 in a hollow position without being subjected to electromagnetic force due to the elasticity of the upper leaf spring 13 and the lower leaf spring 14. An autofocus drive coil 15 is wound around the lens carrier 12, and a drive magnet 16 is installed on the base 10B. When current is applied to the autofocus drive coil 15, the magnetic force generated by the drive magnet 16 on the autofocus drive coil 15 drives the lens carrier 12 to move the lens 11 along the optical axis OO' direction, thereby achieving autofocus.

[0030] As can be understood, in order to control autofocus by energizing and cutting off electricity to the autofocus drive coil 15, the autofocus lens module 100 further includes a first flexible substrate 17, and the autofocus drive coil 15 is connected to a servo control device (which can be provided on the first flexible substrate 17) via the first flexible substrate 17, thereby enabling autofocus to be achieved by energizing and cutting off electricity under the control of the servo control device.

[0031] Preferably, in order to detect the position of the lens 11 during autofocus, 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 provided on the first flexible substrate 17, and the position detection magnet 18B is provided on the lens carrier 12, so that the position detection element 18A can detect the magnetic flux of the position detection magnet 18B, determine the accurate position of the lens carrier 12, and transmit it to the servo control device to realize the position detection function of the lens 11.

[0032] In addition, in one possible embodiment, a first anti-vibration gel 19 may be applied to the lens carrier 12, which can cushion and control the vibration effect of the lens carrier 12 when the autofocus drive coil 15 is suddenly energized, and can achieve a vibration damping effect to realize a more accurate autofocus function.

[0033] The imaging module 200 may be an image sensor, and a light beam from an object that passes through the lens 1 along the optical axis OO' is condensed on the imaging module 200 to form an image.

[0034] The vibration isolation mechanism 300 includes a base 31, a magnet 32, a drive frame 33, and a movable frame 34, which are arranged in this order from the image side to the object side.

[0035] The base 31 is used to mount the magnet 32, and applies a magnetic force to the drive frame 33 and the movable frame 34 through the magnet 32. Preferably, the vibration isolation mechanism 300 includes a second case 35 engaged with the image side of the base 10B, whereby the second case 35, together with the base 10B, surrounds and forms a space for accommodating the base 31, the magnet 32, the drive frame 33, and the movable frame 34, the base 31 is mounted on the second case 35, and a support plate 370 is fixedly installed on the base 31.

[0036] The drive frame 33 is rotatably provided on the base 31, and the rotation axis of the drive frame 33 is perpendicular to the optical axis OO'. The drive frame 33 is provided with a lock drive coil 331 and a lock mechanism 332 located on both sides of the rotation axis. Preferably, the base 31 has a support rod 310 as shown in FIG. 4 protruding in a direction parallel to the optical axis OO' toward the drive frame 33, and the drive frame 33 is rotatably provided on the protruding end of the support rod 310. For example, the drive frame 33 may be pin-joined to the protruding end of the support rod 310 (i.e., the tip of the support rod 310 shown in FIG. 4). More preferably, in one embodiment, the drive frame 33 is provided with an accommodation groove 330 corresponding to the support rod 310, and the protruding end of the support rod 310 extends into the accommodation groove 330 to support the drive frame 33, and the drive frame 33 is rotatably provided on the base 31 around the protruding end of the support rod 310. Furthermore, the tip of the support rod 310 can be designed to be a spherical convex surface, and the bottom surface of the accommodating groove 330 can be designed to be a spherical concave surface correspondingly, thereby reducing the rotational resistance of the drive frame 33 and achieving a better rotation effect.

[0037] 5, 6 and 7, the drive frame 33 may further include a proximal portion 333 close to the optical axis OO′ and a distal portion 334 away from the optical axis OO′, the distal portion 334 is provided with a mounting space 3340 recessed from the image side toward the object side, an opening of the mounting space 3340 faces the base 31 side and accommodates the lock drive coil 331 therein, and the proximal portion 333 is provided with an accommodation space 333 recessed from the object side toward the image side. 0 is provided, the accommodating space 3330 faces the movable frame 34 side and accommodates a lock yoke 341, and the lock drive coil 331 and the lock 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 lock drive coil 331 is farthest from the optical axis OO', the support rod 310 is closest to the optical axis OO', and the lock yoke 341 is located between the lock drive coil 331 and the support rod 310). 7(a) is a diagram showing the local configuration when the drive frame 33 is not rotating, FIG. 7(b) is a diagram showing the local configuration of the drive frame 33 when the magnet 32 ​​attracts the lock drive coil 331 and the drive frame 33 rotates counterclockwise about the rotation axis (shown by the dashed line in FIG. 7(b)), and FIG. 7(c) is a diagram showing the local configuration of the drive frame 33 when the magnet 32 ​​repels the lock drive coil 331 and the drive frame 33 rotates clockwise about the rotation axis (shown by the dashed line in FIG. 7(c)).

[0038] When the lock drive coil 331 is not energized, the magnet 32 ​​does not apply a magnetic force to the de-energized lock drive coil 331, but attracts the lock yoke 341, causing the distal part 334 of the drive frame 33 to receive a downward force and be pushed down by the magnet 32, and the proximal part 333 of the drive frame 33 to be lifted under the action of the lever, thereby bringing the lock mechanism 332 closer to the engaging mechanism 342 to achieve locking, and maintaining the state shown in FIG. 7(b).

[0039] When the lock drive coil 331 is energized, the magnet 32 ​​exerts an upward repulsive force on the energized lock drive coil 331, and this repulsive force resists the attractive force exerted on the lock yoke 341 of the magnet 32, causing the distal part 334 to receive an upward force and be lifted upward away from the magnet 32, and the proximal part 333 of the drive frame 33 is pushed down under the action of the lever, thereby causing the lock mechanism 332 to move away from the engaging mechanism 342 and first reach the state shown in Figure 7(a), and finally reach the state shown in Figure 7(c) to achieve unlocking.

[0040] As a result, by controlling the energization of the lock drive coil 331, the drive frame 33 is rotated, and the lock mechanism 332 is driven to separate from the fitting mechanism 342, thereby realizing the lock release.

[0041] 2 again, the movable frame 34 is used to mount and fix the imaging module 200, and the vibration isolation mechanism 300 further includes a drive module 36 that drives the movable frame 34 to move in an orthogonal plane perpendicular to the optical axis OO' and tilts it with respect to the optical axis OO' to achieve image stabilization. In one possible embodiment, the drive module 36 includes a drive board 360, an anti-vibration coil 361 provided on the drive board 360, a position detection element 362 provided on the drive board 360, and a support plate 363 fixed to the movable frame 34 together with the drive board 360. As a result, the movable frame 34 to which the imaging module 200 and the receiving plate 363 are fixed is supported by the support member 37 and installed on the support plate 370, the support member 37 rotates due to an external force, and the receiving plate 363 and the support plate 370 located on both sides of the support member 37 rotate relatively, and thus the vibration-proof coil 361 on the driving board 360, when receiving the magnetic force of the magnet 32 ​​after being energized, drives the movable frame 34 to move freely within an orthogonal plane perpendicular to the optical axis OO', thereby achieving vibration proof. Correspondingly, the position detection element 362 on the driving board 360 detects the magnetic flux of the magnet 32 ​​to perform accurate position detection and vibration proof control. As can be seen, the surface precision of the receiving plate 363 and the support plate 370 is ensured in the design and manufacturing process, so that the support member 37 can rotate smoothly.

[0042] As can be understood, the anti-vibration coil 361 may be a plurality of single coil windings, or may be a conductive pattern formed on the driving substrate 360. In one possible embodiment, the driving substrate 360 ​​is a flexible substrate. In one possible embodiment, the two anti-vibration coils 361 on each side of the driving substrate 360 ​​apply currents in opposite directions to rotate the movable frame 34 about the optical axis OO', thereby preventing the lens 11 from being misaligned, and realizing four-axis autofocus and anti-vibration.

[0043] Preferably, in one possible embodiment, the signal lines and power lines of the vibration-proof coil 361, the position detection element 362, and the imaging module 200 may be electrically connected by the second flexible substrate 38 located outside the vibration-proof mechanism 300 so as not to affect the movement of the vibration-proof mechanism 300. Furthermore, the second flexible substrate 38 is provided with a curved surface located in the space between the second case 35 and the first case 10A, forming a structure that does not hinder the movement of the vibration-proof mechanism 300. In addition, the first flexible substrate 17 of the autofocus lens module 100 may also be installed outside the autofocus lens module 100 and connected to the second flexible substrate 38 of the vibration-proof mechanism 300. In this way, the first flexible substrate 17 for autofocus can be integrated with the second flexible substrate 38 for image stabilization.

[0044] The movable frame 34 is provided with an anti-vibration yoke 340 and a fitting mechanism 342 facing the lock mechanism 332. In one possible embodiment, the magnet 32 ​​can attract the anti-vibration yoke 340 toward the optical axis OO' (i.e., the center of the orthogonal plane) in the plane perpendicular to the optical axis OO', and can attract the anti-vibration yoke 340 in the direction along the optical axis OO'. This achieves the effect of a magnetic spring, and can effectively reduce the tilt of the imaging module 200 relative to the optical axis OO'. In addition, due to the presence of the anti-vibration yoke 340, the attractive force of the magnet 32 ​​presses and holds the movable frame 34 against the drive frame 33, and the receiving plate 363 and the support plate 370 sandwich the support member 37, preventing the support member 37 from falling off and preventing magnetic leakage.

[0045] When the lock drive coil 331 is not energized, the magnet 32 ​​attracts the lock yoke 341 to press and hold the drive frame 33 against the base 31, and the lock mechanism 332 and the fitting mechanism 342 approach each other and fit together, locking the movable frame 34 and the drive frame 33 together. In this state, the movable frame 34 is in a position such that the optical axis OO' passes through the center of the imaging module 200.

[0046] After current is passed through the lock drive coil 331 to generate a magnetic field, the magnet 32 ​​drives the drive frame 33 to rotate via the lock drive coil 331, moving the lock mechanism 332 and the engagement mechanism 342 away from each other and releasing the engagement, thereby unlocking the movable frame 34 and the drive frame 33.

[0047] Specifically, in one possible embodiment, the locking mechanism 332 is a locking pin and the engagement mechanism 342 is a locking hole, in which the locking pin approaches and inserts into the locking hole to achieve engagement and lock the movable frame 34 and the drive frame 33 together, and the locking pin moves out and away from the locking hole to release the engagement and unlock the movable frame 34 and the drive frame 33.

[0048] More specifically, when the lock release operation is realized, by controlling the power supply to the lock drive coil 331, the magnet 32 ​​applies an upward repulsive force to the energized lock drive coil 331, and the drive frame 33 rotates (the axis of rotation is a straight line perpendicular to the drawing / paper surface and passing through the end of the support rod 310) around the end of the support rod 310 (i.e., the tip shown in FIG. 4), the distal part 334 of the drive frame 33 moves upward, the proximal part 333 moves downward, and the lock pin located in the proximal part 333 moves away from the lock hole to release the lock between the drive frame 33 and the movable frame 34. As a result, if the vibration isolation mechanism 300 is dropped while not in operation and causes an external impact, the imaging device obtains information from components such as a gyroscope, which is an attitude and acceleration detection element, and realizes the locking of the drive frame 33 and the movable frame 34 at the moment of the drop, thereby protecting the vibration isolation mechanism 300 from impact and preventing wear and indentations from occurring during the drop impact, which would impair the image stabilization function. Furthermore, in the process of assembling the imaging device, by locking the drive frame 33 and the movable frame 34, centering adjustment can be achieved without the need for a large-scale jig, making the assembly less difficult.

[0049] As can be understood, the specific forms of the lock mechanism 332 and the engagement mechanism 342 are also interchangeable, and the lock mechanism 332 may be set in a lock hole, and the engagement mechanism 342 may be set in a lock pin. The number of lock pins may be one, two or more. Preferably, the number of lock pins is at least two. In one possible embodiment, two lock pins are sequentially arranged at intervals from each other in an edge region close to the optical axis OO' of the proximal part 333 along a direction parallel to the rotation axis of the drive frame 33, and each lock pin extends from the proximal part 333 to the movable frame 34 along a direction parallel to the optical axis OO' and is inserted into the lock hole.

[0050] Preferably, in one possible embodiment, the vibration-proof mechanism 300 further includes a second vibration-proof gel 39 disposed between the movable part and the fixed part, which can mitigate and control the vibration effect of the movable frame 34 when the vibration-proof coil 361 is suddenly energized, and can achieve a vibration-damping effect and a more accurate vibration-proof function. Of course, the second vibration-proof gel 39 can be replaced with an adhesive such as a lubricant or a dust trap.

[0051] In addition, the imaging module 200 may include an image sensor and an infrared cut filter. The movable frame 34 and the imaging module 200 form an integrated structure, which, when used in combination with the drive frame 33, realizes a locking and unlocking function, increases the structural rigidity, and strengthens drop protection, while reducing the number of parts of the imaging module 200, improving the perpendicularity of the imaging module 200 with respect to the optical axis OO', preventing tilting, contributing to a compact and low-profile design, and simultaneously improving the ease of assembly and the vibration-proof performance.

[0052] The embodiment of the present invention relates to an imaging system including the imaging device of the above embodiment, and the imaging system may include a collapsible zoom mechanism or a folded optical structure. For example, as shown in Fig. 8, the imaging system in the embodiment of the present invention includes a folded optical mechanism 400 and the imaging device of the above embodiment.

[0053] Compared to the prior art, by providing the imaging device of the above embodiment to the curved optical mechanism 400, it is possible to achieve locking and contact between the movable frame and the drive frame depending on whether or not electricity is passed through the drive coil, which suppresses the inherent vibration of the image stabilization mechanism during assembly and makes the design and assembly less difficult. In addition, by locking the movable frame and the drive frame in the event of a drop impact, it is possible to prevent the entire mechanism from being subjected to impact, which would cause wear and indentations, and to prevent the image stabilization function from being impaired.

[0054] As shown in FIG. 9, the embodiment of the present invention further relates to a camera including an aperture mechanism 500 and the imaging device of the above embodiment.

[0055] Compared to the prior art, by providing an imaging device of the above embodiment in combination with aperture mechanism 500 in a camera, it is similarly possible to achieve locking and contact between the movable frame and the drive frame by the presence or absence of current passing through the drive coil, which suppresses the inherent vibration of the image stabilization mechanism during assembly and makes the design and assembly less difficult. In addition, by locking the movable frame and the drive frame in the event of a drop impact, it is possible to prevent the entire mechanism from being subjected to impact, which would cause wear and indentations, and to prevent impairment of the image stabilization function.

[0056] As can be understood, the above-mentioned imaging device, imaging module, and camera can be applied to various electronic devices having imaging functions, and such electronic devices may be mobile terminals such as mobile phones, tablets, smart watches, etc., or may be laptops or other terminals.

[0057] As shown in FIG. 10, the embodiment of the present invention further relates to an electronic device with a photographing function, which includes a device body 600 and the imaging device of the above embodiment provided in the device body.

[0058] Compared to the prior art, by providing an imaging device of the above embodiment in an electronic device, it is similarly possible to achieve locking and contact between the movable frame and the drive frame by the presence or absence of current flow through the drive coil, which suppresses the inherent vibration of the image stabilization mechanism during assembly and reduces the difficulty of design and assembly. In addition, by locking the movable frame and the drive frame in the event of a drop impact, it is possible to prevent the entire mechanism from being subjected to impact, which would cause wear and indentations, and to prevent impairment of the image stabilization function.

[0059] Although the above-mentioned embodiments are specific examples for implementing the present invention, it should be understood by those skilled in the art that in practical applications, various changes in form and details can be made without departing from the spirit and scope of the present invention.
