Technical Field

[0001] The present invention relates to the field of camera technology, and in particular to a dynamic anti-shake imaging system. Background Art

[0002] With the continuous development of camera technology and the increasing demand for camera functions, the need for lens module improvement and innovation is urgent. Currently, image stabilization and focus are among the basic requirements of lens modules. Achieving high performance requirements such as low power consumption, high precision, and fast response is particularly important.

[0003] In the prior art, the anti-shake module performs the anti-shake function by moving the magnet through the anti-shake bracket. The movement of the magnet will cause the magnetic field in the space to change. When a product contains more than two lens modules, multiple magnets in different modules move at the same time, causing the magnetic fields of different modules to interfere with each other, resulting in magnetic field disorder.

[0004] Therefore, how to improve the poor module anti-shake and focusing effects and poor imaging effects caused by magnetic field disturbance when more than two lens modules work simultaneously, so as to enhance the user experience, is a technical problem that technicians in this field currently need to solve.

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0062] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0063] In the description of the present invention, it should be understood that the terms "inside" and "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0064] The purpose of the present invention is to provide a dynamic anti-shake imaging system that effectively improves the magnetic interference between motors in a module while achieving anti-shake and focusing functions.

[0065] It should be noted that, in this embodiment, the Z direction in the drawings is defined as the optical axis direction, the Y direction is defined as the first direction, and the X direction is defined as the second direction. The optical axis direction, the first direction and the second direction are perpendicular to each other.

[0066] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 To achieve the above-mentioned purpose, the present invention provides a dynamic anti-shake imaging system, comprising at least two lens modules, each of which includes a base 1, a lens assembly 11 connected to the base 1, an image sensing component 8 spaced apart from the lens assembly 11 in the optical axis direction, and a focusing component that drives the image sensing component 8 and the lens assembly 11 to move relative to each other in the optical axis direction. The focusing component includes a magnet 2 fixed relative to the base 1 and a focusing carrier 5 fixed relative to the image sensing component 8. The focusing carrier 5 is movably connected to the base 1, and a focusing coil 6 is provided on the focusing carrier 5. When energized, the focusing coil 6 can drive the focusing carrier 5 and the image sensing component 8 to move synchronously along the optical axis under the drive of the magnet 2.

[0067] A focusing coil 6 is provided on the focusing carrier 5 movably connected to the base 1, and the magnets 2 in the lens module are fixed relative to the base 1 in the lens module. The magnet 2 provides a magnetic force for the focusing coil 6 after power is turned on, so that the focusing coil 6 drives the focusing carrier 5 and the image sensing component 8 fixed relatively to the focusing carrier 5 to move along the optical axis to approach or move away from the lens assembly 11, and changes the distance between the image sensing component 8 and the lens assembly 11 in the optical axis direction to achieve focusing. With such a setting, on the basis of achieving focusing, the magnet 2 does not move during the focusing process, so that the magnetic field in the space is stable, thereby ensuring that the magnetic field disorder between the lens modules will not be caused by the simultaneous movement of the magnet 2, so that when there are more than two lens modules in the product focusing at the same time, each lens module can work normally without being interfered by the magnetic field of other lens modules, the focusing effect is more stable, and the shooting image is clearer, so as to improve the user experience. At the same time, it can improve the phenomenon in the prior art that the arrangement gap between the lens assembly and other modules is set too large to avoid the mutual influence of the magnetic fields in different modules.

[0068] In one possible embodiment, each lens module further includes an anti-shake assembly, which is located on one side of the base 1 in the optical axis direction. The anti-shake assembly includes an anti-shake carrier 3 and an anti-shake coil 4. The anti-shake carrier 3 is movably connected to the base 1 and is used to mount the lens assembly 11. The anti-shake coil 4 is connected to the anti-shake carrier 3. When energized, the anti-shake coil 4 can drive the anti-shake carrier 3 and the lens assembly 11 to move perpendicular to the optical axis under the influence of the magnet 2. By connecting the anti-shake assembly to the side of the base 1 in the optical axis direction, the anti-shake coil 4 of the anti-shake assembly can, when energized, drive the anti-shake carrier 3, on which the lens assembly 11 is mounted, to move perpendicular to the optical axis under the influence of the magnetic field of the magnet 2, thereby achieving the anti-shake function.

[0069] See also Figure 7 and Figure 8 In a possible embodiment, the base body 1 is provided with a first accommodating cavity 11 extending along the optical axis, the focusing carrier 5 is located in the first accommodating cavity 11, and the inner side wall of the base body 1 is provided with a first protrusion 12 extending toward the focusing carrier 5, and the magnet 2 is fixed to the side of the first protrusion 12 facing the anti-shake carrier 3; by assembling the focusing carrier 5 of the focusing assembly into the first accommodating cavity 11, the focusing coil 6 connected to the focusing carrier 5 can drive the focusing carrier 5 to move along the optical axis in the first accommodating cavity 11 under the action of the magnetic field of the above-mentioned magnet 2 after being energized, and the image sensing component 8 is connected to the focusing carrier 5 and can move along the optical axis with the focusing carrier 5, thereby changing the distance between the image sensing component 8 and the lens assembly 11, thereby realizing the focusing function.

[0070] In one possible embodiment, the magnet 2 includes a first magnet 21 located in a first direction and a second magnet 22 located in a second direction; the anti-shake coil includes a first anti-shake coil corresponding to the first magnet 21 and a second anti-shake coil corresponding to the second magnet 22.

[0071] It should be noted that the first anti-shake coil is located on one side of the first magnet 21 in the optical axis direction, and forms a group of anti-shake drive components with the first magnet 21. The second anti-shake coil is located on one side of the second magnet 22 in the optical axis direction, and forms a group of anti-shake drive components with the second magnet 22. The number and position of the first magnet 21 correspond one-to-one to the number and position of the first anti-shake coils, and the number and position of the second magnet 22 correspond one-to-one to the number and position of the second anti-shake coils. Four groups of anti-shake drive components can be set, including two first magnets 21 spaced apart in the first direction, and two second magnets 22 spaced apart in the second direction. By controlling the two first anti-shake coils to generate electromagnetic forces in basically the same direction and / or the two second anti-shake coils to generate electromagnetic forces in basically the same direction, the movement of the anti-shake carrier 3 in a plane perpendicular to the optical axis direction can be made more stable and reliable, and the anti-shake function can be achieved by controlling the movement amount and direction of the anti-shake carrier 3 by changing the applied current.

[0072] It can be understood that the magnet 2 is fixed on the base, and the focusing coil 6 and the anti-shake coil 4 share the same set of magnets 2. After the focusing coil 6 and the anti-shake coil 4 are energized, the anti-shake function and the focusing function are respectively realized, and the magnet 2 does not move during the anti-shake and focusing process, so that the magnetic field in the same lens module space is relatively stable, and thus, on the basis of realizing the anti-shake and focusing functions, the phenomenon of unstable magnetic field in the lens module can be effectively improved, and the phenomenon of mutual influence between the magnets in the anti-shake component and the magnets in the focusing component when anti-shake and focusing are performed at the same time in the prior art can be avoided. At the same time, in this embodiment, the magnet 2 does not need to move with the lens component 11, which can reduce the volume of the lens module.

[0073] In a possible embodiment, the lens module also includes a circuit board 7, which is fixedly connected to the other side of the base 1 in the optical axis direction. The image sensing component 8 is movably connected to the circuit board 7. The anti-shake assembly also includes an anti-shake flexible circuit board 9 (Flexible Printed Circuit, FPC) and an anti-shake support component 10. The anti-shake flexible circuit board 9 is arranged on the side of the anti-shake carrier 3 facing the base 1 and is electrically connected to the circuit board 7. The anti-shake coil 4 is located on the side of the anti-shake flexible circuit board 9 away from the anti-shake carrier 3 and is electrically connected to the anti-shake flexible circuit board 9. The anti-shake flexible circuit board 9 can be attached to the anti-shake carrier 3, and metal can be buried in the anti-shake carrier 3 to achieve electrical connection between the anti-shake flexible circuit board 9 and the circuit board 7. The anti-shake support component 10 is connected to the anti-shake carrier 3 and the base body 1, and is used to support the anti-shake carrier 3. The anti-shake support component 10 can be but is not limited to one or a combination of flat spring clips, vertical spring clips, suspension wires, balls, damping glue, and ball spring clips. The number of anti-shake support components 10 can be set to four, and the four anti-shake support components 10 are connected to different positions of the anti-shake carrier 3 and the base body 1 to provide support force and balancing force for the anti-shake carrier 3.

[0074] The anti-shake flexible circuit board 9 is also connected to Hall sensors. These Hall sensors include a first Hall sensor 91 electrically connected to the anti-shake flexible circuit board 9 and disposed within the first anti-shake coil, and a second Hall sensor 92 electrically connected to the anti-shake flexible circuit board 9 and disposed within the second anti-shake coil. The first Hall sensor 91 is used to detect the displacement of the anti-shake carrier 3 in a first direction, and the second Hall sensor 92 is used to detect the displacement of the anti-shake carrier 3 in a second direction. Electrical connection to the anti-shake coil 4 can be achieved by embedding metal in the anti-shake carrier 3 and attaching the anti-shake flexible circuit board 9. Closed-loop control of the electrical connection between the first Hall sensor 91 and the second Hall sensor 92 can also be achieved. The anti-shake carrier 3 can be electrically connected to the electrical components within the base 1 via flat springs, 3D bent springs, and suspension wires in the anti-shake support component 10, thereby achieving closed-loop feedback control.

[0075] In one possible embodiment, the anti-shake carrier 3 is provided with a second protrusion 31, which is located on the side of the anti-shake carrier 3 facing the image sensing component 8. A mounting hole 32 extending in the optical axis direction is opened on the second protrusion 31, and the mounting hole 32 is used for assembling the lens assembly 11. A second accommodating cavity 51 extending along the optical axis direction is provided in the focusing carrier 5, and the image sensing component 8 partially extends into the second accommodating cavity 51; the second protrusion 31 can be located outside the second accommodating cavity 51 so that the movement of the lens assembly 11 installed in the mounting hole 32 is not restricted by the space of the second accommodating cavity 51, which can increase the size of the lens assembly; the second protrusion 31 can also be at least partially extended into the second accommodating cavity 51, and there is a gap between the second protrusion 31 and the inner wall of the focusing carrier 5 to form an avoidance space for the lens assembly 11 to move in the direction perpendicular to the optical axis, so that the side of the lens assembly 11 facing the image sensing component 8 can move in the second accommodating cavity 51, which can reduce the overall thickness of the lens module.

[0076] See also Figure 9 and Figure 10 In a possible embodiment, the focusing assembly further includes a focusing flexible circuit board 16 and a focusing support component 13.

The focusing coil 6 and the magnet 2 form a focusing drive assembly to provide the required driving force for the focusing function. The magnet 2 provides a permanent magnetic field. The Lorentz force generated in the permanent magnetic field by applying current to the focusing coil 6 drives the focusing carrier 5 along the optical axis. The focus carrier 5 is fixed to the image sensing component 8, and the current applied to the focus coil 6 is further changed to control the movement of the focus carrier 5, thereby driving the image sensing component 8 to move and adjust the focal length to achieve focus. The focus support component 13 is connected to the focus carrier 5 and the base 1 and is located on the side of the focus carrier 5 facing the anti-shake carrier 3. The focus support component 13 provides support and rebound force for the focus carrier 5, as well as a guide for movement along the optical axis. The focus support component 13 can be, but is not limited to, a spring, a ball, a damping rubber, or a combination of a ball spring. The flat spring in the focus support component 13 can be used to connect the electrical connection to the electrical part of the base 1, thereby realizing a closed-loop feedback control function.
