Description

Technical Field

[0001] The present invention relates to the field of OIS motor technology, in particular to the field of sensor shift OIS motor technology, and specifically to a sensor anti-shake motor. Background Art

[0002] At present, the micro camera used in smart phones is the main application field of high-end anti-shake camera technology. As far as the existing technology is concerned, as a typical solution of high-end technology in this field, the Sensor-Shift technology is used to replace the ordinary OIS optical image stabilization currently carried, so as to improve the camera's dynamic capture effect. Before this, the most commonly used OIS optical image stabilization solution on smart phone products was achieved by driving the lens with a VCM motor for angle correction. However, such a solution has long had the disadvantages of high power consumption, limited anti-shake effect, large product size, and high unit price. As the scenes of mobile phone photography become more and more abundant, the demand for anti-shake is also increasing. In other words, it is inevitable to improve the shooting effect of smart phones in the scene of sports photography; in addition, the terminal brands are increasingly strict in controlling the cost of component products. The main reason why OIS has not been popularized on some affordable mobile phones is that the cost is too high. Finally, since the VCM motor product of the OIS function is large in size, it is contrary to the terminal brand's demand for a thin and light appearance of the whole machine, and the Sensor-Shift technology can just avoid this problem. From the above, we can see that the implementation of Sensor-Shift technology is expected to bring more detailed improvements to mobile terminal products. If the new Sensor-Shift technology is adopted, it may be implemented through MEMS OIS. The main feature is that the relevant components are located at the bottom of the CMOS image sensor, which can move the image sensor very quickly and accurately in the X / Y direction.

[0003] In addition to adding some more precise parts, the use of Sensor-Shift technology also has complex assembly processes that are different from traditional ones, which poses great challenges to manufacturers such as FPCs and modules. There are a large number of technical problems that need to be solved for precision assembly. Therefore, related manufacturing, especially assembly problems, are currently the biggest obstacle to the Sensor-Shift technology. Summary of the invention

[0004] In order to solve the problem of large size of the anti-shake motor in the prior art due to structural design and assembly constraints, the present application provides a sensor anti-shake motor, which further improves the integration and compactness of the structure by redesigning the anti-shake mechanism, focusing mechanism and conductive mechanism, so that the overall volume of the anti-shake motor is further compressed, which is more in line with the current application requirements of refined and ultra-thin smart devices, making it applicable to more scenarios and more conducive to the layout design of anti-shake cameras for smart devices.

[0005] The present invention closely redesigns the anti-shake mechanism of the sensor, and at the same time, further optimizes the design of the anti-shake motor focusing mechanism and the conductive mechanism for powering the coil in the anti-shake mechanism, thereby obtaining a new assembly structure technology, so that the radial size and axial size of the anti-shake motor are further reduced and optimized.

[0006] In order to achieve the above purpose, the technical solution adopted in this application is:

[0007] A sensor anti-shake motor includes an external support structure composed of an outer shell and a bottom plate, wherein a focus mechanism, a carrier, an anti-shake mechanism and a conductive mechanism are installed in the external support structure, wherein the focus mechanism is connected to the carrier through a front suspension spring and a rear suspension spring respectively, wherein the anti-shake mechanism is connected to the carrier through an anti-shake suspension wire, and wherein the conductive mechanism is electrically connected to the anti-shake mechanism, the front suspension spring, the rear suspension spring and the anti-shake mechanism. Working principle: The carrier is fixedly or detachably fixedly connected to the external support structure, and the focus mechanism can rely on the front suspension spring and the rear suspension spring to move back and forth axially relative to the carrier to achieve the purpose of focusing and focusing; the use of a front and rear double suspension spring structure can improve the stability and accuracy of the focus mechanism. Similarly, the anti-shake mechanism is connected to the carrier through an anti-shake suspension wire to achieve movement in a radial plane perpendicular to the axial direction to achieve the purpose of sensor anti-shake. The conductive mechanism is a mechanism that provides power for the anti-shake mechanism to achieve anti-shake and the focus mechanism to achieve focusing and focusing. It has integrity and compactness, avoiding the problem of large number and fragmentation of existing conductive components, thereby improving the stability of power supply and signal transmission.

[0008] As a preferred structural setting of the present invention, the focusing mechanism includes a lens holder, a lens assembly is coaxially mounted on the lens holder, the lens holder is connected to the upper surface of the carrier through the front suspension spring, and the lens holder is connected to the lower surface of the carrier through the rear suspension spring; the lens holder is provided with a plurality of focusing coils on the side close to the carrier, and a plurality of magnets corresponding to the focusing coils are mounted on the carrier. The front suspension spring and the rear suspension spring have stability in the radial plane and good elasticity and deformation ability in the axial direction, which makes the lens holder have a good stability effect in the non-focusing state, and one of the purposes of adopting the double-layer suspension design structure is also for this; at the same time, the double suspension spring structure design has a better response ability when focusing than the existing VCM voice coil motor, making the focusing speed faster and the control more precise.

[0009] As one of the key technical innovations of the present invention, preferably, the anti-shake mechanism includes a sensor bracket, the outer side of the sensor bracket is connected to the carrier through the anti-shake suspension wire, the sensor bracket includes a bracket body, the center position of the bracket body is provided with a first installation cavity for installing an imaging sensor, the side wall of the bracket body is provided with a plurality of second installation cavities for installing a coil bracket, a coil is installed on the coil bracket, and the position of any of the coils corresponds to the position of the magnet. As one of the preferred layout modes, the number of the magnets and the coil brackets are both four, and they are arranged around the bracket body in an axially symmetrical or centrally symmetrical manner. The above layout mode is only one of the preferred layout modes, and three or more coil brackets and magnets can also be used in accordance with corresponding and uniformly distributed at equal central angles to achieve substantially the same technical effect. Here, it is worth noting that different numbers and different layout modes require different system debugging, and the size and time of the electrical signal control are not the scope that needs to be disclosed and claimed for protection in this application, so they will not be described in detail here, but as long as a symmetrical structure layout is adopted, whether it is centrally symmetrical or axially symmetrical, as long as such an inventive concept is followed, the same or substantially the same technical effect can be obtained. Here, the applicant emphasizes that in this application, the symmetrical layouts mentioned for all magnets and coils include axisymmetric structures and centrally symmetrical structures. The coil support is provided with at least two independent metal conductors respectively connected to the two ends of the coil, and the other end of the metal conductor is electrically connected to the conductive mechanism.

[0010] Furthermore, the coil support is provided with a winding post for the coil to be wound, and any of the metal conductors includes at least a second contact and a third contact, the second contact extends out of the coil support to form a connection point, and the third contact is arranged at the bottom of the coil support and is electrically connected to the conductive mechanism. The beneficial effects of the metal conductor being built into the coil support and multiple contacts being arranged outside are: first, there is no need to perform separate insulation treatment on the metal conductor, and good insulation between each other is achieved through the coil support; second, multiple contacts are arranged on the surface of the coil support or extended outward to form other connection points, which is conducive to connecting other components that need power supply in different directions, such as coils, etc.; third, the use of this structure can save space to the greatest extent, reduce space occupancy, and improve the compactness of the structure, laying the foundation for minimizing the external volume of the product as much as possible.

[0011] In order to facilitate manufacturing and simplify the assembly process, while ensuring good assembly accuracy and consistency, preferably, first card slots are provided on the inner walls of both ends of the second mounting cavity on the bracket body, and a second card slot is provided on the inner wall close to the first mounting cavity, and the coil bracket is provided with a first boss and a second boss for embedding in the first and second card slots, respectively. The coil bracket is detachably connected to the bracket body through the above structure, so that the assembly of the coil does not depend on the entire bracket body, but only requires a single coil bracket to complete the assembly, including the metal conductor can also be completely separated from the bracket body, which can bring great convenience in the manufacturing and assembly process, and can reduce the manufacturing cost. However, in order to reduce or even eliminate the precision loss caused by changing the fixed structure to a detachable fixed structure as much as possible, the purpose of using the first card slot and the second card slot is to achieve precise assembly and connection, and simplify the difficulty of manufacturing and assembly while ensuring the stability of the connection.

[0012] As one of another technical improvement points of the present application, preferably, the conductive mechanism includes an FPC soft board, the FPC soft board includes a connecting part, a transmission part and a back plate, the connecting part is provided with a plug, and the back plate is provided with a connecting contact electrically connected to the third contact, so that any coil is electrically connected to the plug; the inner side of the transmission part is also provided with a first contact respectively connected to the front suspension wire spring and the rear suspension wire spring.

The bent suspension wires are symmetrically arranged relative to the center of the anti-shake suspension wire, and any bent suspension wire includes at least one bending point.

[0015] Beneficial effects:

[0016] The present invention redesigns the anti-shake mechanism and the conductive mechanism to make the structure more compact, with higher integration and integrity. It also simplifies the assembly process and reduces the assembly difficulty while meeting the requirement of reducing the product volume. At the same time, the power supply structure for each coil is also integrated with the sensor bracket, making the power supply structure more compact and eliminating the cumbersomeness and instability caused by many existing tiny FPC welding.

[0036] In conjunction with the instruction manual Figure 1 and Figure 2 A sensor anti-shake motor shown in the figure includes an external support structure composed of an outer shell 1 and a bottom plate 11, wherein a focus mechanism, a carrier 5, an anti-shake mechanism and a conductive mechanism are installed in the external support structure, wherein the focus mechanism is connected to the carrier 5 through a front suspension spring 2 and a rear suspension spring 7 respectively, wherein the anti-shake mechanism is connected to the carrier 5 through an anti-shake suspension wire 10, and wherein the conductive mechanism is electrically connected to the anti-shake mechanism, the front suspension spring 2, the rear suspension spring 7 and the anti-shake mechanism. Working principle: the carrier 5 is fixedly or detachably fixedly connected to the external support structure, and the focus mechanism can move back and forth axially relative to the carrier 5 by means of the front suspension spring 2 and the rear suspension spring 7 to achieve the purpose of focusing and focusing; the front and rear double suspension spring structure can improve the stability and accuracy of the focus mechanism. Similarly, the anti-shake mechanism is connected to the carrier 5 through the anti-shake suspension wire 10 to achieve movement in a radial plane perpendicular to the axial direction, thereby achieving the purpose of sensor anti-shake. The conductive mechanism is a mechanism that provides power for the anti-shake mechanism to achieve anti-shake and the focus mechanism to achieve focusing and focusing. It has integrity and compactness, avoiding the problem of large number and fragmentation of existing conductive components, thereby improving the stability of power supply and signal transmission.

[0037] In this embodiment, the focusing mechanism includes a lens holder 4, a lens assembly 3 is coaxially mounted on the lens holder 4, the lens holder 4 is connected to the upper surface of the carrier 5 through the front suspension spring 2, and the lens holder 4 is connected to the lower surface of the carrier 5 through the rear suspension spring 7; the lens holder 4 is provided with a plurality of focusing coils on the side close to the carrier 5, and a plurality of magnets 6 corresponding to the focusing coils are mounted on the carrier 5. The front suspension spring 2 and the rear suspension spring 7 have stability in the radial plane and good elasticity and deformation ability in the axial direction, so that the lens holder 4 has a good stability effect in the non-focusing state, and one of the purposes of adopting the double-layer suspension design structure is also for this; at the same time, the double suspension spring structure design has a better response ability when focusing compared with the existing VCM voice coil motor, so that the focusing speed is faster and the control is more precise.

[0038] Embodiment 2:

[0039] As one of the key technical innovations of the present invention, based on Example 1, Figure 6 and Figure 7 As shown, the anti-shake mechanism includes a sensor bracket 8, the outer side of the sensor bracket 8 is connected to the carrier 5 through the anti-shake suspension wire 10, the sensor bracket 8 includes a bracket body 81, the center position of the bracket body 81 is provided with a first installation cavity 82 for installing an imaging sensor, and the side wall of the bracket body 81 is provided with a plurality of second installation cavities 83 for installing a coil bracket 84, and a coil 85 is installed on the coil bracket 84, and the position of any coil 85 corresponds to the position of the magnet 6. As one of the preferred layout modes, the number of the magnet 6 and the coil bracket 84 are both four, and they are arranged around the bracket body 81 in an axially symmetrical or centrally symmetrical manner. The above layout mode is only one of the preferred layout modes, and three or more coil brackets 84 and magnets 6 can also be used in a corresponding and uniformly distributed manner with equal central angles to achieve substantially the same technical effect. It is worth noting here that different quantities and different layout methods require different system debugging. The size and time of the electrical signal control are not within the scope that needs to be disclosed and protected in this application, so they will not be described in detail here. However, as long as a symmetrical structural layout is adopted, whether it is centrally symmetrical or axially symmetrical, as long as such an inventive concept is followed, the same or substantially the same technical effect can be obtained. Here, the applicant emphasizes that in this application, the symmetrical layouts mentioned for all magnets 6 and coils 85 include axially symmetrical structures and centrally symmetrical structures. At least two independent metal conductors 86 respectively connected to the two ends of the coil 85 are arranged in the coil bracket 84, and the other end of the metal conductor 86 is electrically connected to the conductive mechanism.

[0040] In this embodiment, the coil support 84 is provided with a winding post for the coil 85 to be wound, and any of the metal conductors 86 includes at least a second contact 861 and a third contact 862, the second contact 861 extends out of the coil support 84 to form a connection point, and the third contact 862 is arranged at the bottom of the coil support 84 and electrically connected to the conductive mechanism. The beneficial effects of the metal conductor 86 being built into the coil support 84 and multiple contacts being arranged outside are: first, there is no need to perform separate insulation treatment on the metal conductor 86, and good insulation between each other is achieved through the coil support 84; second, multiple contacts are arranged on the surface of the coil support 84 or extended outward to form other connection points, which is conducive to connecting other components that need power supply in different directions, such as coils, etc.; third, the use of this structure can save space to the greatest extent, reduce space occupancy, improve the compactness of the structure, and lay the foundation for minimizing the external volume of the product as much as possible. It is worth noting that the coil support 84 described in this application is an integral injection molding structure to further improve the stability of the coil 85 and the convenience of installation.

[0041] In order to facilitate manufacturing and simplify the assembly process while ensuring good assembly accuracy and consistency, in this embodiment, first slots 831 are provided on the inner walls of both ends of the second mounting cavity 83 on the bracket body 81, and a second slot 832 is provided on the inner wall close to the first mounting cavity 82. The coil bracket 84 is respectively provided with a first boss 841 and a second boss 842 for embedding in the first slot 831 and the second slot 832. Figure 6 As shown. The coil support 84 is detachably connected to the support body 81 through the above structure, so that the assembly of the coil 85 does not rely on the entire support body 81, but only requires a single coil support 84 to complete the assembly, including the metal conductor 86 can also be completely separated from the support body 81, which can bring great convenience in the manufacturing and assembly process, and can reduce the manufacturing cost. However, in order to reduce or even eliminate the precision loss caused by changing the fixed structure to a detachable fixed structure as much as possible, the purpose of using the first card slot 831 and the second card slot 832 is to achieve precise assembly and connection, and simplify the difficulty of manufacturing and assembly while ensuring the stability of the connection.

[0042] Example 3

[0043] Based on Example 2, as one of the technical improvements of this application, in conjunction with the attached specification Figure 3-Figure 5As shown, the conductive mechanism includes an FPC soft board 9, and the FPC soft board 9 includes a connecting portion 91, a transmission portion 92 and a back plate 95. The connecting portion 91 is provided with a plug 94, and the back plate 95 is provided with a connecting contact electrically connected to the third contact 862, so that any coil 85 is electrically connected to the plug 94; the inner side of the transmission portion 92 is also provided with a first contact 93 respectively connected to the front suspension wire spring 2 and the rear suspension wire spring 7. The electric signal driving the coil 85 to generate magnetic force passes through the plug 94, the connecting portion 91, the transmission portion 92, the connecting contact, the third contact 862, the metal conductor 86 in sequence, and finally reaches the coil 85. The coil is energized to generate magnetic force and the magnet 6 generates force to achieve the anti-shake effect.

[0044] Furthermore, the connection between the connection part 91 and the transmission part 92 has a bending structure that connects the connection part 91 and the transmission part 92 perpendicularly to each other, and the transmission part 92 is arranged on the outside of the bracket body 81 and has a gap with the bracket body 81 for the bracket body 81 to move. The anti-shake suspension wire 101 is composed of an outer ring 101, an inner ring 103, and at least two bent suspension wires 102 connecting the outer ring 101 and the inner ring 103. The bent suspension wires 102 are symmetrically arranged relative to the center of the anti-shake suspension wire 101, and any one of the bent suspension wires 102 includes at least one bending point. The bending point refers to the number of bends of the same bending suspension wire 102. One bending point means that the bending suspension wire 102 at least surrounds half of the adjacent two sides of the inner circle 103, that is, the coverage rate is one quarter of the entire inner circle 103. If a bending suspension wire 102 contains two bending points, then the bending suspension wire 102 at least covers half of the circumference of the entire inner circle 103; the two bending suspension wires 102 are arranged in a central symmetrical manner. The more bending points the bending suspension wire 102 has, the longer the overall length of the suspension wire, the larger the maximum anti-shake movement margin that can be met, and the higher the linear controllability during the movement and deformation process.

[0045] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
