[0001]    This application claims the benefit of Taiwan Patent Application Serial No.104119438, filed Jun. 16, 2015, the subject matter of which is incorporated herein by reference. 
       BACKGROUND OF INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The invention relates to a thin-plate-typed rotating module, and more particularly to an anti-shake compensation module that applies an electromagnetic driving unit to drive a thin elastic-plated rotating element to undergo pivotal motions about two different axes. This invention can be applied to an optical system to avoid possible instability caused by unexpected shaking. 
         [0004]    2. Description of the Prior Art 
         [0005]    In an optical system consisted of optical lenses and image-capturing modules, such as the optical system for a camera, a video recorder or the like, may meet an obscure image caused by a bias or a shake in an optical path of the image-capturing module from unexpected foreign incidents or handshakes. A common resort to such a situation is to provide a digital or optical compensation mechanism for correcting the obscure image caused by unexpected shaking. The digital compensation mechanism is to analyze and process the image captured by the image-capturing module in a digital manner so as to obtain a much clearer digitalized image. In the art, the digital compensation mechanism is also called as a digital anti-shake mechanism. On the other hand, the optical compensation mechanism is to introduce an additional optical lens set or an anti-shake device to the image-capturing module. In the art, this type of the compensation mechanism is also called as an optical anti-shake mechanism. Nevertheless, current optical anti-shake mechanisms in the market place usually involve complicated or cumbersome structures. Namely, the conventional optical anti-shake mechanism is usually featured in complicate manufacturing, difficult assembling, a higher cost and an irreducible volume. Thus, an improvement thereupon is definitely needed.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0045]    The invention disclosed herein is directed to a thin-plate-typed rotating module. In the following description, numerous details are set forth in order to provide a thorough understanding of the present invention. It will be appreciated by one skilled in the art that variations of these specific details are possible while still achieving the results of the present invention. In other instance, well-known components are not described in detail in order not to unnecessarily obscure the present invention. 
         [0046]    The design of the thin-plate-typed rotating module in this present invention is mainly to produce a specific multi-framed rotating element by forming trenches on a thin-plated spring complex, and further to introduce an electromagnetic driving unit to drive the rotating element to perform a twin-axial pivotal motion in a limited degree, so that an improved optical anti-shake apparatus with a shake-compensation function can be thus obtained. In this apparatus, the electromagnetic driving unit is consisted of plural permanent magnets and coils that are positioned by specific-designed inner and outer carrier structures so as to form a simple-structured, easy-assembled, small-occupation and less-cost anti-shake compensation apparatus. 
         [0047]    Refer now to  FIG. 1  to  FIG. 3 ; where  FIG. 1  is a schematic exploded view of a first embodiment of the thin-plate-typed rotating module in accordance with the present invention.  FIG. 2A  is a top view of  FIG. 1 ,  FIG. 2B  is a cross-sectional view of  FIG. 2A  along line A-A, and  FIG. 3  is an enlarged view of the rotating element of  FIG. 1 . 
         [0048]    As shown in  FIG. 1 , the first embodiment  1  of the thin-plate-typed rotating module  1 , defined with an X-Y-Z orthogonal coordinate system (having an X axis, a Y axis and a Z axis) and an optical path  4  extending in the Z axis, includes a rotating element  10 , a driving unit  20 , a position-detecting unit  30 , a base board  40 , and an optical path-adjusting element  50 . 
         [0049]    The rotating element  10  located on the optical path  4  can perform a pivotal motion in a limited degree at least in a first axial direction  101  and a second axial direction  102  perpendicular to the first axial direction  101 . The first axial direction  101  and the second axial direction  102  are both perpendicular to the Z axis and parallel respectively to the X axis and the Y axis. Referring to  FIG. 3 , in this first embodiment, the rotating element  10  can be formed as a rectangular thin-plated spring complex. The thin-plated spring complex has four lateral sides and further includes an outer frame  11 , a middle frame  12 , and an inner plate  13 . The inner plate  13  has a plane facing the optical path  4  to define thereon the first axial direction  101  and the second axial direction  102 . The middle frame  12  circles around a periphery of the inner plate  13  by at least one first through trench  131  for spacing and two first connection ribs  132  in the first axial direction  101  for connection. Typically, the two first connection ribs  132  are located to opposing lateral sides of the inner plate  13  so as to divide the at least one first through trench  131  into two U-shape first through trenches  131 . The connection between the inner plate  13  and the middle frame  12  is provided by the two first connection ribs  132 . The outer frame  11  circles around a periphery of the middle frame  12  by at least one second through trench  121  for spacing and two second connection ribs  122  in the second axial direction  102  for connection. Typically, the two second connection ribs  122  are located to opposing lateral sides of the middle frame  12  so as to divide the at least one second through trench  121  into two U-shape second through trenches  121 . The connection between the middle frame  12  and the outer frame  1 ′ is provided by the two second connection ribs  132 . Namely, the two first connection ribs  132  and the two second connection ribs  122  are located to the four lateral sides of the rectangular thin-plated spring complex, respectively, so as to utilize the elasticity of thin-plated spring complex to allow the inner plate  13  to undergo a limited pivotal motion with respect to the outer frame  11  about the two first connection ribs  132  (i.e. the first axial direction  101 ) and also to allow the inner plate  13  to undergo another limited pivotal motion with respect to the outer frame  11  about the two second connection ribs  122  (i.e. the second axial direction  102 ). Upon such an arrangement, the rotating element  10  can provide the designed two-axial rotating function. Hence, by providing through trenches to the thin-plated spring complex so as purposely to form a multi-frame structure, the simple-structured, small-occupation and less-cost rotating element  10  can be provided in a unique-piece manner. 
         [0050]    As shown in  FIG. 1  to  FIG. 3 , the driving unit  20  is connected with the rotating element  10  at one side and engages the base board  40  at another side, so as to drive the rotating element  10  to undergo limited pivotal motions in the first axial direction  101  and the second axial direction  102 . In this first embodiment, the driving unit  20  embodied as an electromagnetic driving unit can include at least an inner carrier structure  21 , an outer carrier structure  22 , at least a first magnet  23 , at least a second magnet  24 , at least a first coil  25 , at least a second coil  26  and a plurality of coil-fixing structures  27 . 
         [0051]    The inner carrier structure  21  is connected with a bottom of the inner plate  13  in a co-moving manner. The outer carrier structure  22  is connected with a bottom of the outer frame  11  and further engages the base board  40  to form a fixed structure. 
         [0052]    One of the first magnet  23  and the corresponding first coil  25  is located at the inner carrier structure  21 , while another thereof is located at the outer carrier structure  22 . In this first embodiment, one first magnet  23  is located at each of two lateral sides of the inner carrier structure  21  that are close to the two second connection ribs  122 , and one first coil  25  is located at each of two lateral sides of the outer carrier structure  22  that are close to the two second connection ribs  122 , via the coil-fixing structure  27  at position by corresponding to the respective first magnet  23 . By energizing the two first coils  25 , an electromagnetic force can be induced to push the two first magnets  23  at the inner carrier structure  21  together with the inner plate  13  to undergo a pivotal motion about the first axial direction  101 . 
         [0053]    One of the second magnet  24  and the corresponding second coil  26  is located at the inner carrier structure  21 , while another thereof is located at the outer carrier structure  22 . In this first embodiment, one second magnet  24  is located at each of two lateral sides of the outer carrier structure  22  that are close to the two first connection ribs  132 , and one second coil  26  is located at each of two lateral sides of the outer carrier structure  22  that are close to the two first connection ribs  132 , via the coil-fixing structure  27  at position by corresponding o the respective second magnet  24 . By energizing the two second coils  26 , an electromagnetic force can be induced to push the two second magnets  24  at the inner carrier structure  21  together with the inner plate  13  to undergo another pivotal motion about the second axial direction  102 . 
         [0054]    The inner carrier structure  21  formed as a square frame structure has a first rectangular connection portion  211  to connect with the bottom of the inner plate  13 . The first rectangular connection portion  211  has four first flanges  212  protrusive in a direction away from the inner plate  13 . Each of the four first flanges  212  is shaped as a rectangle and perpendicular to the two neighboring first flanges  212  at opposing ends thereof. Each of the first flanges  212  has a first accommodation space  213 . The outer carrier structure  22  formed as another square frame structure has a second rectangular connection portion  221  to connect with the bottom of the outer frame  11 . The second rectangular connection portion  221  has four second flanges  222  protrusive in a direction away from the outer frame  11 . Each of the four second flanges  222  is shaped as a rectangle and perpendicular to the two neighboring second flanges  222  at opposing ends thereof. Each of the second flanges  222  has a second accommodation space  223 . 
         [0055]    In the first embodiment, the first magnet  23  is mounted in the corresponding first accommodation space  213  of the inner carrier structure  21 , and the first coil  25  is mounted in the corresponding second accommodation space  223  of the outer carrier structure  22  via the coil-fixing structure  27 . Similarly, the second magnet  24  is mounted in the corresponding first accommodation space  213  of the inner carrier structure  21 , and the second coil  26  is mounted in the corresponding second accommodation space  223  of the outer carrier structure  22  via the coil-fixing structure  27 . As described above, by providing these two specific square frame structures (the inner and outer carrier structures  21 ,  22 ) to mount and position the first and second magnets  23 ,  24  and the first and second coils  25 ,  26 , the module  1  of the present invention can be easily applied to an optical system such as a digital camera or a digital recorder. Further, the thin-plate-typed rotating module  1  of the present invention can then be produced in a simple-structured, easy-assembled, limited-occupied and less-prized manner. 
         [0056]    In the first embodiment of the present invention, the position-detecting unit  30  includes a Hall-effect sensing magnet  31 , at least one X-axis position-detecting sensor  32  (two shown in the figure), and at least one Y-axis position-detecting sensor  33  (two shown in the figure). The Hall-effect sensing magnet  31  is mounted on the inner carrier structure  21 , and the X-axis position-detecting sensor  32  and the Y-axis position-detecting sensor  33  are individually mounted to predetermined positions on the base board  40  respective to the Hall-effect sensing magnet  31 . Namely, the X-axis position-detecting sensor  32  and the Y-axis position-detecting sensor  33  of the position-detecting unit  30  are used to detect position differences between every two position-detecting sensors and thereby to calculate relative angular changes. Thus, any pivotal displacement of the inner carrier structure  21  with respect to the rotating element  10  can be detected. Since the aforesaid sensors  32 ,  33  can be adopted or selected from the conventional products already in the market place, and thus details thereabout are omitted herein. 
         [0057]    In the first embodiment of the present invention, the base board  40  can be a printed circuit board (PCB) including a control module  41  and electrically coupled with the position-detecting unit  30  and the driving unit  20 . According to the pivotal displacement of the rotating element  10  detected by the position-detecting unit  30 , the base board  40  can control the driving unit  20  to drive the rotating element  10  to rotate so as to compensate possible deviations in the optical path  4  caused by shakes or the like impacts. Since the aforesaid base board  40  and the control module  41  can be adopted or selected from the conventional products already in the market place, and thus details thereabout are omitted herein. 
         [0058]    In the first embodiment of the present invention, the optical path-adjusting element  50  is located on a surface plane of the inner plate  13  of the rotating element  10  to reflect lights in the optical path  4  for a purpose of adjusting the optical path, and can be one of a mirror and a prism. 
         [0059]    In the following embodiments of the present invention, for a large amount of elements are the same or resembled to those in the foregoing first embodiment described above, thus details thereabout would be omitted herein, and those elements would be assigned the same names and numbers. However, to those elements that are similar to the respective elements in the aforesaid first embodiment, though the same names and numbers are still applied, yet individual tailing letters would be added to the corresponding numbers. 
         [0060]    Refer now to  FIG. 4  to  FIG. 6 ; where  FIG. 4  is a schematic exploded view of a second embodiment of the thin-plate-typed rotating module in accordance with the present invention,  FIG. 5A  is a top view of  FIG. 4 ,  FIG. 5B  is a cross-sectional view of  FIG. 5A  along line B-B, and  FIG. 6  is an enlarged view of the lower spring complex of  FIG. 4 . 
         [0061]    Largely, the second embodiment of the thin-plate-typed rotating module shown from  FIG. 4  to  FIG. 6  is similar structurally to the first embodiment shown from  FIG. 1  to  FIG. 3 , and thus descriptions for the same elements would be omitted herein. The major difference between the first and the second embodiments is that the thin-plate-typed rotating module  1   a  of the second embodiment further includes a lower spring complex  60 . The lower spring complex  60  further includes at least one outer fixation end  61 , at least one inner fixation end  62  and at least one connection portion  63 . The connection portion  63  is winding, elastic and bendable. Two opposing connection ends  631 ,  631 ′ of the connection portion  63  are connected to the outer fixation end  61  and the inner fixation end  62 , respectively. The outer fixation end  61  is connected with the outer carrier structure  22   a,  and the inner fixation end  62  is connected with the inner carrier structure  21   a , such that the weight of the inner carrier structure  21   a  can be elastically supported by the outer carrier structure  22   a.    
         [0062]    In the present invention, the lower spring complex  60  can be made of a conductive metallic material, and can further include a first separation spacing  64  and a second separation spacing  65 . The first separation spacing  64  is perpendicular to the second separation spacing  65  by a crossing manner so as together to divide the inner fixation end  62  of the lower spring complex  60  into four independent plate segments  62   a ˜ 62   d.  Each of the independent plate segments  62   a ˜ 62  of the inner fixation end  62  is connected to the corresponding connection portion  63  and thus the corresponding outer fixation end  61 , such that four spring units  60 (A)˜ 60 (D) can thus be formed. These four continuous-structured spring units  60 (A)˜ 60 (D) are arranged into a ring shape with the optical path  4  as the center line. By fixing these four outer fixation ends  61  and these four independent plate segments  62   a ˜ 62   d  to the outer carrier structure  22   a  and the inner carrier structure  21   a  respectively, the inner carrier structure  21   a  can then be elastically supported by the outer carrier structure  22   a  through the lower spring complex  60 . As shown in  FIG. 6 , each of the outer fixation ends  61  further includes a protrusive lead  611  extending vertically therefrom and parallel to the Z axis. Through the protrusive lead  611 , electric connection with the driving unit  20   a  and the position-detecting unit  30  can thus be established. 
         [0063]    In the second embodiment  1   a  of the thin-plate-typed rotating module, the first magnets  23   a  and the second magnets  24   a  of the driving unit  20   a  are individually mounted inside the four corresponding second accommodation spaces  223   a  of the four second flanges  222   a  of the outer carrier structure  22   a.  In addition, the first coils  25   a  and the second coils  26   a  respective to the first magnets  23   a  and the second magnets  24   a  are individually mounted inside the corresponding first accommodation space  213   a  of the four first flanges  212   a  of the inner carrier structure  21   a.    
         [0064]    Refer now to  FIG. 7  to  FIG. 9 ; where  FIG. 7  is a schematic exploded view of a third embodiment of the thin-plate-typed rotating module in accordance with the present invention,  FIG. 8A  is a top view of  FIG. 7 ,  FIG. 8B  is a cross-sectional view of  FIG. 8A  along line C-C, and  FIG. 9  is an enlarged view of the rotating element of  FIG. 7 . 
         [0065]    Since the third embodiment of the thin-plate-typed rotating module shown from  FIG. 7  to  FIG. 9  is largely similar structurally to the second embodiment shown from  FIG. 4  to  FIG. 6 , and thus descriptions for the same elements would be omitted herein. The major difference between the second the third embodiments is that the rotating element  10   b  in the second embodiment is a rectangular thin-plated spring complex having four lateral sides. The rotating element  10   b  includes an outer frame  11   b , a middle frame  12   b,  and an inner plate  13   b.  The inner plate  13   b  has a plane surface facing the optical path  4  and being defined with the first axial direction  101  and the second axial direction  102 . The driving, unit  20   a  is to push the inner plate  13   b  to undergo pivotal motions with respect to the outer frame  11   b  about the first axial direction  101  and the second axial direction  102 . 
         [0066]    The middle frame  12   b  circles around the periphery of the inner plate  13   b,  and thereby at least one first through trench  131   b  between the middle frame  12   b  and the inner plate  13   b  and two first connection ribs  132   b  lying in the first axial direction  101  and connecting the middle frame  12   b  and the inner plate  13   b  are formed. Namely, the inner plate  13   b  is connected with the middle frame  12   b  via the two first connection ribs  132   b.  A first separation cut  14   b  along the first axial direction  101  is continuously formed to divide the inner plate  13   b,  the middle frame  12   b  and the two first connection ribs  132   b.  The outer frame  11   b  circles around the periphery of the middle frame  12   b,  and thereby at least one second through trench  121   b  between the middle frame  12   b  and the outer frame  11   b  and two second connection ribs  122   b  lying in the second axial direction  102  and connecting the middle frame  12   b  and the outer frame  11   b  are formed. Namely, the middle frame  12   b  is connected with the outer frame  11   b  via the two second connection ribs  122   b.  A second separation cut  15   b  along the second axial direction  102  is continuously formed to divide the middle frame  12   b,  the outer frame  11   b  and the two second connection ribs  122   b.    
         [0067]    Namely, the first separation cut  14   b  and the second separation cut  15   b  are largely orthogonally crossed so as thereby to divide the rotating element  10   b  into four independent elastic units  10   b (A)˜ 10   b (D), each of the four independent elastic units  10   b (A)˜ 10   b (D) is located at one corner of the rotating element  10   b , and has a portion of the first connection rib  132   b  and a portion of the second connection rib  122   b.  In particular, each of the four independent elastic units  10   b (A)˜ 10   b (D) is formed as a unique-piece spring structure. 
         [0068]    In this third embodiment of the present invention, the rotating element  10   b  can be made of a conductive elastic metallic material, and can be further divided into four independent elastic units  10   b (A)˜ 10   b (D). Each outer frame  11   b  of any of the independent elastic units  10   b (A)˜ 10   b (D) has a first protrusive lead  111   b  extending vertically at a specific place thereof for providing electric coupling. Also, each inner plate  13   b  of any of the independent elastic units  10   b (A)˜ 10   b (D) has a second protrusive lead  133   b  extending vertically at another specific place thereof for providing electric coupling. In particular, the first protrusive leads  111   b  and the second protrusive leads  133   b  are all extended in the same direction, parallel to the Z axis substantially. The first protrusive leads  111   b  and the second protrusive leads  133   b  are to provide electric coupling with one of the driving unit  20  and the position-detecting unit  30 . 
         [0069]    Referring now to  FIG. 10 , a schematic exploded view of a fourth embodiment of the thin-plate-typed rotating module in accordance with the present invention is shown. Since the fourth embodiment of the thin-plate-typed rotating module shown in  FIG. 10  is largely similar structurally to the first embodiment shown in  FIG. 1 , and thus descriptions for the same elements would be omitted herein. The major difference between the fourth and the first embodiments is that, in the fourth embodiment  1   c , the driving unit  20   b  is an electromagnetic driving unit including at least an inner carrier structure  21   b,  an outer carrier structure  22   b,  at least one induced magnet  28   b , at least one first coil  25   b  (two shown in the figure) and at least one second coil  26   b  (two shown in the figure). The inner carrier structure  21   b  engages and thus co-moves with the inner plate  13 , and the outer carrier structure  22   b  is fixed at the outer frame  11 . 
         [0070]    The induced magnet  28   b  formed as a cuboid includes an engagement surface  281   b , a third magnetic surface  284   b  opposing to the engagement surface  281   b,  two opposing first magnetic surfaces  282   b  located as two opposing vertical sides to connect the engagement surface  281   b  and the third magnetic surface  284   b,  and two opposing second magnetic surfaces  283   b  connecting the two first magnetic surfaces  282   b  and also located as another two opposing vertical sides to connect the engagement surface  281   b  and the third magnetic surface  284   b.  The engagement surface  281   b  is to locate the induced magnet  28   b  onto the inner carrier structure  21   b.    
         [0071]    The first coil  25   b  is mounted at the outer carrier structure  22   b  at a place corresponding to the first magnetic surface  282   b.  Upon such an arrangement, by energizing the first coil  25   b,  a corresponding electromagnetic force can be produced to push the first magnetic surface  282   b  associated with the inner plate  13  to undergo a corresponding pivotal motion in the first axial direction  101 . In addition, the second coil  26   b  is mounted at the outer carrier structure  22   b  at a place corresponding to the second magnetic surface  283   b.  Thus, by energizing the second coil  26   b,  a corresponding electromagnetic force can be produced to push the second magnetic surface  283   b  associated with the inner plate  13  to undergo another pivotal motion in the second axial direction  102 . In this fourth embodiment, the first coil  25   b  is mounted to the corresponding second accommodation space  223   b  of the outer carrier structure  22   b  via the coil-fixing structure  27   b,  and similarly the second coil  26   b  is mounted to the corresponding second accommodation space  223   b  of the outer carrier structure  22   b  via the coil-fixing structure  27   b.    
         [0072]    The position-detecting unit  30   b,  located at a predetermined place on the base board  40  and respective to the induced magnet  28   b , includes at least one X-axis position-detecting sensor  32   b  (two shown in the figure) and at least one Y-axis position-detecting sensor  33   b  (two shown in the figure). The X-axis position-detecting sensor  32   b  and the Y-axis position-detecting sensor  33   b  are individually located on the base board  40  by facing the third magnetic surface  284   b  of the induced magnet  28   b.  By providing the X-axis position-detecting sensor  32   b  and the Y-axis position-detecting sensor  33   b  to detect the induced magnet  28   b,  the angling of the third magnetic surface  284   b  can thus be realized. 
         [0073]    Refer now to  FIG. 11 ,  FIG. 12 ,  FIG. 13A  and  FIG. 13B ; where  FIG. 11  is a schematic perspective view of a fifth embodiment of the thin-plate-typed rotating module in accordance with the present invention,  FIG. 12  is a schematic exploded view of  FIG. 11 ,  FIG. 13A  is a schematic view showing an application of the thin-plate-typed rotating module of  FIG. 11  to a mobile phone, and  FIG. 13B  is a schematic cross-sectional view showing a portion of  FIG. 13A . As shown, the fifth embodiment  1   d  of the thin-plate-typed rotating module is largely similar structurally to the first embodiment shown in  FIG. 1 , and thus descriptions for the same elements would be omitted herein. The major difference between the fifth and the first embodiments is that the fifth embodiment  1   d  further includes a fixation base  70 , an angle-detecting module  80 , a lower spring complex  90  and an end frame  100 . The angle-detecting module  80  is mounted inside a fixation hole of the fixation base  70 . The fixation base  70  is fixed to the inner carrier structure  21  by buckling between a plurality of buckle hooks  72  protrusive from the periphery of the fixation base  70  and the corresponding buckle notches  214  structured at the inner carrier structure  21 . By providing the angle-detecting module  80  to detect the angular deviation of the inner carrier structure  21  caused mainly by hand shake, then a relevant compensation for correcting the deviation can thus be calculated. In addition, the end frame  100  is provided to fix orderly the lower spring complex  90  and the base board  40  to the outer carrier structure  22 . The lower spring complex  90  is thus electrically coupled with the base board  40 . In the fifth embodiment of the present invention, the angle-detecting module  80  can be a gyroscope. Since the angle-detecting module  80  (the gyroscope for example) can be adopted or selected from the conventional products already in the market place, and thus details thereabout are omitted herein. 
         [0074]    Referring now to  FIG. 13A  and  FIG. 13B , in the fifth embodiment  1   d , the thin-plate-typed rotating module  1   d  is applied into a mobile phone  110  at a place forming a 45-degree angle with an image-capturing module  300  of the mobile phone, such that the optical path-adjusting element  50  of the thin-plate-typed rotating module  1   d  can right aim at an optical hole  201  of the mobile phone, so that foreign images can be reflected to the image-capturing module  300  through the optical hole  201 . Of course, the location and angling of the thin-plate-typed rotating module  1   d  in the mobile phone shall meet various structuring of the corresponding optical hole  201 ; for example, to a front surface or a lateral side of the mobile phone  110 . 
         [0075]    While the present invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be without departing from the spirit and scope of the present invention.
