Description

Cameras and video devices

[0001] This application is based on and claims the priority of Japanese patent application No. 2023-125369, filed on August 1, 2023. The entire contents of the Japanese patent application are hereby incorporated into this application by reference. Technical Field

[0002] The present application relates to the field of optical technology, and in particular to an imaging device and a camera. Background Art

[0003] With the rapid development of photography 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.

[0004] The lens drive device used in portable electronic devices typically includes a focusing mechanism for adjusting the focal point along the optical axis and an anti-vibration mechanism for adjusting the lens in a plane orthogonal to the optical axis. These mechanisms are typically integrated and driven electromagnetically by coils and magnets. Typically, the coil is affixed to the periphery of the lens holder. When the coil is energized and subjected to the magnetic force of the magnet, the lens holder, to which the coil is affixed, is able to move the lens along the optical axis under the influence of this magnetic force, achieving focusing. When a user holds a portable electronic device to shoot, any lens shake caused by hand tremors can be corrected by the lens holder driving the lens to move perpendicular to the optical axis.

[0005] 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 three-dimensional movement of the lens, it inevitably brings about the problem of drop impact. Since the anti-vibration mechanism usually does not work during drop impact, the entire mechanism is prone to wear or indentation after impact, which in turn leads to damage to the anti-shake function.

[0006] Therefore, it is necessary to provide a camera and an imaging device to solve the above problems. Technical Solutions

[0007] The purpose of some embodiments of the present application is to provide a camera device and a camera to reduce the difficulty of assembly and avoid wear and indentation caused by falling and impact, which may damage the anti-shake function.

[0009] An embodiment of the present application further provides a camera, including an aperture mechanism and the above-mentioned camera device.

[0010] In addition, the locking mechanism is a locking hole, and the matching mechanism is a locking pin.

The locking pin withdraws and moves away from the locking hole to release the matching and release the lock of the movable frame and the driving frame.

[0011] In addition, 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. 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.

[0012] In addition, 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 the 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 the side of the movable frame and accommodates the locking yoke.

[0029] In order to make the purpose, technical solutions and advantages of this application more clear, some embodiments of this application are further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0030] An embodiment of the present application relates to a camera device, as shown in Figures 1 to 2, comprising: an autofocus lens module 100 having an optical axis OO', an imaging module 200 for cooperating with the autofocus lens module 100 to form an image, and an anti-vibration mechanism 300 for preventing vibration; the anti-vibration mechanism 300 comprises, from the image side to the object side,: a base 31; a magnet 32 ​​arranged on the base 31; a drive frame 33, rotatably arranged on the base 31, the rotation axis of the drive frame 33 being perpendicular to the optical axis OO', please refer to Figures 3 and 4, the drive frame 33 is provided with a locking drive coil 331 located on one side of the rotation axis, a locking yoke 341 located on the other side of the rotation axis and a locking mechanism 332; a movable frame 34, on which the imaging module 200 is fixedly arranged , the movable frame 34 drives the imaging module 200 to move relative to the optical axis OO' to achieve anti-shake, and a matching mechanism 342 opposite to the locking mechanism 332 is provided on the movable frame 34; when the locking drive coil 331 is not energized, the magnet 32 ​​attracts the locking yoke 341 to press the drive frame 33 on the base 31, and the locking mechanism 332 and the matching mechanism 342 approach and cooperate with each other to lock the movable frame 34 and the drive frame 33 together; 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, so as to release the lock of the movable frame 34 and the drive frame 33.

[0031] Compared with the prior art, the embodiment of the present application is characterized in that relative locking drive coils 331 and locking mechanisms 332 are respectively provided on the rotatable drive frame 33, and a matching mechanism 342 that matches the locking mechanism is provided on the movable frame 34 to which the imaging module 200 is fixed, so that when the locking drive coil 331 is in the unpowered working state, the magnet 32 ​​generates an attractive force on the locking yoke 341, so that the drive frame 33 is pressed on the base 31, and the locking mechanism 332 and the matching mechanism 342 approach each other and match with each other to lock the movable frame 34 and the drive frame 33 together; when the locking drive coil 331 is in the energized working state, the magnet 32 ​​generates an electromagnetic force on the locking drive coil 331 to drive the drive 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 lock of the movable frame 34 and the drive 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 avoiding damage to the anti-shake function.

[0032] In the embodiment of the present application, the autofocus lens module 100 includes a first shell 10A, a base 10B, a lens 11, a lens bracket 12, an upper leaf spring 13, a lower leaf spring 14, an autofocus drive coil 15, and a drive magnet 16, as shown in FIG2 .

[0033] The first housing 10A and the base 10B together form a housing space for accommodating the other components of the autofocus lens module 100. The lens 11 has an optical axis OO' and is used to converge light for imaging by the imaging module 200. A lens holder 12 is disposed within the housing 10 to support and secure the lens 11. The lens holder 12 is secured to the first housing 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'. The elasticity of the upper and lower leaf springs 13 and 14 allows the lens holder 12 to maintain the lens 11 in a hollow position without being affected by electromagnetic forces. An autofocus drive coil 15 is wound around the lens holder 12, and a drive magnet 16 is disposed on the base 10B. When the autofocus drive coil 15 is energized, the drive magnet 16 generates a magnetic force on the autofocus drive coil 15, driving the lens holder 12 to move the lens 11 in the direction of the optical axis OO', thereby achieving autofocus.

[0034] It can be understood that in order to energize and deenergize 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 provided on the first flexible circuit board 17) via the first flexible circuit board 17 so as to achieve autofocus by energizing and deenergizing under the control of the servo control device.

[0035] In addition, to detect the position of the lens 11 during the autofocus process, the autofocus lens module 100 also includes a position detection element 18A and a position detection magnet 18B. In the embodiment of the present application, 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 holder 12. Thus, the position detection element 18A can detect the magnetic flux of the position detection magnet 18B to determine the precise position of the lens holder 12, and then transmit the information to the servo control device to realize the position detection function of the lens 11.

[0036] In addition, the lens holder 12 can also be coated with a first anti-vibration gel 19. The first anti-vibration gel 19 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.

[0037] 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.

[0038] 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.

[0039] The base 31 is used to support the magnet 32, so that the magnet 32 ​​can apply magnetic force to the drive frame 33 and the movable frame 34. In the embodiment of the present application, the anti-vibration mechanism 300 also includes a second housing 35 that is buckled onto the image side of the base 10B, so that the second housing 35 and the base 10B together enclose 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 housing 35, and a support plate 370 is fixed to the base 31.

[0040] The drive frame 33 is rotatably mounted on the base 31, with the rotation axis of the drive frame 33 being perpendicular to the optical axis OO'. 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. In an embodiment of the present application, a support rod 310, as shown in FIG4 , protrudes from the base 31 in a direction parallel to the optical axis OO' toward the drive frame 33. The drive frame 33 is rotatably mounted at the protruding end of the support rod 310. For example, the drive frame 33 may be pivotally connected to the protruding end of the support rod 310 (i.e., the top end of the support rod 310 shown in FIG4 ). In an embodiment of the present application, 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. The drive frame 33 is rotatably mounted on the base 31 around the protruding end of the support rod 310. In addition, the end of the support rod 310 can be designed as a spherical convex surface, and correspondingly, the bottom surface of the accommodating groove 330 is a spherical concave surface. In this way, the resistance to the rotation of the driving frame 33 can be reduced, achieving a better rotation effect.

[0041] Please refer to Figures 5, 6 and 7. In an embodiment of the present application, 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 the 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 the side of the movable frame 34 and accommodates the 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 the local structure of the driving frame 33 when it is not rotating, Figure 7 (b) shows a schematic diagram of the local structure of the driving frame 33 when the magnet 32 ​​attracts and locks the driving coil 331, causing the driving frame 33 to rotate counterclockwise around the rotation axis (indicated by the dotted line in Figure 7 (b)), and Figure 7 (c) shows a schematic diagram of the local structure of the driving frame 33 when the magnet 32 ​​repels and locks the driving coil 331, causing the driving frame 33 to rotate clockwise around the rotation axis (indicated by the dotted line in Figure 7 (c)).

[0042] When the locking coil 331 is not energized, the magnet 32 ​​will not exert a magnetic force on the de-energized locking coil 331, but will attract the locking yoke 341, causing the distal end 334 of the drive frame 33 to be subjected to a downward force and pressed downward toward the magnet 32. The proximal end 333 of the drive frame 33 is then lifted up by the lever, thereby driving the locking mechanism 332 to approach the mating mechanism 342 to achieve locking, and maintain the state shown in FIG7 (b).

[0043] When the locking coil 331 is energized, the magnet 32 ​​exerts an upward repulsive force on the energized locking coil 331. This repulsive force overcomes the attractive force exerted by the magnet 32 ​​on the locking yoke 341, causing the distal end 334 to be subjected to an upward force and rise upward away from the magnet 32. The proximal end 333 of the drive frame 33 is pressed downward under the action of the lever, thereby driving the locking mechanism 332 away from the matching mechanism 342 to first reach the state shown in Figure 7 (a) and then finally reach the state shown in Figure 7 (c) to achieve unlocking.

[0044] In this way, the driving frame 33 is driven to rotate by controlling the power supply of the locking driving coil 331 , so as to drive the locking mechanism 332 away from the matching mechanism 342 to achieve unlocking.

[0045] Referring again to FIG. 2 , the movable frame 34 is used to support and secure the imaging module 200. The anti-vibration mechanism 300 further includes a drive module 36 that drives the movable frame 34 to move within an orthogonal plane perpendicular to the optical axis OO' and tilt relative to the optical axis OO' to achieve anti-shake. In the embodiment of the present application, the drive module 36 includes a drive substrate 360, an anti-vibration coil 361 disposed on the drive substrate 360, a position detection element 362 disposed on the drive substrate 360, and a bearing plate 363 secured to the movable frame 34 together with the drive substrate 360. Thus, the movable frame 34, to which the imaging module 200 and the supporting plate 363 are fixed, is supported by the supporting component 37 and is arranged on the supporting plate 370, so that the supporting component 37 can rotate under the action of an external force, so that the supporting plates 363 and the supporting plates 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, when subjected to the magnetic force of the magnet 32 ​​after being energized, can drive the movable frame 34 to move freely in an orthogonal plane perpendicular to the optical axis OO' to achieve anti-vibration. 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 is understandable that the surface accuracy of the supporting 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.

[0046] It is understood that the anti-vibration coils 361 can be multiple single coil windings or a conductive pattern formed on the drive substrate 360. In the embodiment of the present application, the drive substrate 360 ​​is a flexible substrate. In the embodiment of the present application, the two anti-vibration coils 361 on each side of the drive substrate 360 ​​can apply currents in opposite directions, causing the movable frame 34 to rotate relative to the optical axis OO', preventing rotational deviation of the lens 11 and achieving four-axis automatic focusing and vibration isolation.

[0047] In the embodiment of the present application, the anti-vibration coil 361, position detection element 362, and the signal and power lines of the imaging module 200 can all be electrically connected via the second flexible circuit board 38 located outside the anti-vibration mechanism 300, thereby preventing interference with the movement of the anti-vibration mechanism 300. In the embodiment of the present application, the second flexible circuit board 38 is provided with a curved surface located within the space between the second housing 35 and the first housing 10A, thereby forming a structure that prevents interference with the movement of the anti-vibration mechanism 300. It should be noted that the first flexible circuit board 17 of the autofocus lens module 100 can also be located outside the autofocus lens module 100, thereby connecting to the second flexible circuit board 38 of the anti-vibration mechanism 300. In this way, the first flexible circuit board 17 for autofocus can be integrated with the second flexible circuit board 38 for anti-shake.

[0048] The movable frame 34 is provided with an anti-vibration yoke 340 and a matching mechanism 342 opposite to the locking mechanism 332. In an embodiment of the present application, 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.

[0049] When the locking drive coil 331 is de-energized, the magnet 32 ​​attracts the locking yoke 341, pressing the drive frame 33 against the base 31. This causes the locking mechanism 332 and the engaging mechanism 342 to approach and engage with each other, locking the movable frame 34 and the drive frame 33 together. In this state, the movable frame 34 is positioned so that the optical axis OO' passes through the center of the imaging module 200.

[0050] 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, causing the locking mechanism 332 and the matching mechanism 342 to move away from each other and release the matching, thereby releasing the lock of the movable frame 34 and the drive frame 33.

[0051] In an embodiment of the present application, the locking mechanism 332 is a locking pin, and the mating mechanism 342 is a locking hole. The locking pin approaches and extends into the locking hole to achieve mating and lock the movable frame 34 and the driving frame 33 together. The locking pin withdraws and moves away from the locking hole to release the mating and release the lock of the movable frame 34 and the driving frame 33.

[0052] Furthermore, when unlocking, the power supply to the lock drive coil 331 is controlled, causing the magnet 32 ​​to exert an upward repulsive force on the energized lock drive coil 331, thereby causing the drive frame 33 to rotate about the distal end of the support rod 310 (i.e., the top end shown in FIG. 4 ). The rotation axis is a straight line perpendicular to the drawing / paper and passing through the distal end of the support rod 310. This causes the distal end 334 of the drive frame 33 to move upward and the proximal end 333 to move downward, moving the locking pin located at the proximal end 333 away from the locking hole and releasing the lock between the drive frame 33 and the movable frame 34. In this manner, if the anti-vibration mechanism 300 is dropped while not in operation, causing an external impact, the camera device can obtain information through components such as the gyroscope, which serves as a posture and acceleration detection element, and thereby lock the drive frame 33 and the movable frame 34 at the moment of the drop. This protects the anti-vibration mechanism 300 from the impact and prevents wear and indentation caused by the drop impact, which could damage the anti-shake function. In addition, during the process of assembling the camera device, the driving frame 33 and the movable frame 34 can be locked to achieve centering without the need for large-scale clamps, thereby reducing the difficulty of assembly.

[0053] 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 can be set as a locking hole, while the matching mechanism 342 can be set as a locking pin. In addition, the number of locking pins can be one, two or more. In an embodiment of the present application, there are more than two locking pins. In an embodiment of the present application, more than two locking pins are sequentially arranged at intervals from each other in a direction parallel to the rotation axis of the driving frame 33 in the edge area of ​​the proximal portion 333 close to the optical axis OO', and each locking pin extends from the proximal portion 333 in a direction parallel to the optical axis OO' toward the movable frame 34 and extends into the locking hole.

[0054] In the embodiment of the present application, the anti-vibration mechanism 300 further includes a second anti-vibration gel 39 disposed between the movable and fixed components. This second anti-vibration gel 39 is capable of buffering and controlling the vibration of the movable frame 34 when the anti-vibration coil 361 is suddenly energized, thereby providing a shock-absorbing effect and achieving more precise anti-vibration performance. Of course, the second anti-vibration gel 39 can also be replaced by an adhesive such as lubricating oil or a dust collector.

[0055] 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 drive frame 33 to realize locking and unlocking functions to improve structural rigidity and enhance 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 for miniaturization and low-profile design, and improves both assembly and vibration resistance.

[0056] The present invention relates to a camera system including the camera device of the above-mentioned embodiment. The camera system may have a sunken zoom mechanism or a periscope optical path structure. For example, as shown in FIG8 , the camera system of the present invention includes a periscope optical mechanism 400 and the camera device of the above-mentioned embodiment.

[0057] Compared with the prior art, the camera device of the above embodiment is arranged on the periscope optical mechanism 400, and the movable frame and the driving frame can be locked and contacted by simply turning on or off the driving coil. 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 and the driving frame during a drop impact, thereby preventing the anti-shake function from being damaged.

[0058] An embodiment of the present application further relates to a camera, as shown in FIG9 , comprising: an aperture mechanism 500 and the camera device of the above embodiment.

[0059] Compared with the prior art, the camera device of the above embodiment that is provided in the camera and cooperates with the aperture mechanism 500 can also achieve locking and contacting of the movable frame and the driving frame by controlling whether the driving coil is energized or not. 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 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.

[0060] It is understandable that the aforementioned camera device, camera system and camera can be applied to various electronic devices with shooting functions, such as mobile phones, tablet computers, smart watches and other portable terminals, or laptop computers or other terminals.

[0061] An embodiment of the present application further relates to an electronic device with a shooting function, as shown in FIG10 , comprising: a device body 600 and the camera device of the above embodiment arranged on the device body.

[0062] With respect to 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 controlling whether the driving coil is energized or not. This not only facilitates suppressing the inherent vibration of the anti-shake structure during the assembly process, 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 and the driving frame during a drop impact, thereby preventing the anti-shake function from being damaged.

[0063] Those skilled in the art will appreciate that the above embodiments are specific embodiments for implementing the present application, and that in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present application.
