[0076] Figure 1 A perspective view of an optical element driving mechanism 1000 according to some embodiments of the present invention is shown. Figure 2 This diagram shows an exploded view of an optical element driving mechanism 1000 according to some embodiments of the present invention. The overall structure of the optical element driving mechanism 1000 will be described in detail below; please refer to [reference needed]. Figure 1 as well as Figure 2 .
[0077] According to some embodiments of the present invention, the optical element driving mechanism 1000 includes a fixed part 1100, a movable part 1200, a driving component 1300, a control component 1400, an elastic component 1500, a pair of guiding elements 1600, a pair of magnetic suction components 1700, and a plurality of buffer elements 1810 and 1820.
[0078] According to some embodiments of the present invention, the fixing part 1100 includes an upper cover 1110 and a base 1120. The upper cover 1110 is fixedly connected to the base 1120 to form a space for accommodating other components of the optical element driving mechanism 1000.
[0079] According to some embodiments of the present invention, the movable part 1200 is a carrier connecting an optical element (not shown). The optical element has an optical axis O, which is substantially parallel to the Z-axis. The movable part 1200 is movable relative to the fixed part 1100. The driving assembly 1300 is used to drive the movable part 1200 to move relative to the fixed part 1100 in a first dimension, wherein the first dimension movement refers to movement along the optical axis O.
[0080] According to some embodiments of the present invention, the driving assembly 1300 includes a first driving part 1310 and a second driving part 1320 to provide a larger driving force to the movable part 1200. The first driving part 1310 and the second driving part 1320 are disposed on opposite sides of the optical element driving mechanism 1000. The first driving part 1310 and the second driving part 1320 are electrically independent of each other to drive the movable part 1200 to move relative to the fixed part 1100 in a first dimension.
[0081] According to some embodiments of the present invention, the first driving unit 1310 includes a driving magnetic element 1311, a driving coil 1312, and a magnetically conductive element 1313. The second driving unit 1320 includes a driving magnetic element 1321, a driving coil 1322, and a magnetically conductive element 1323.
[0082] According to some embodiments of this utility model, driving magnetic elements 1311 and 1321 and magnetic conductive elements 1313 and 1323 are disposed on the upper cover 1110 of the fixed part 1100. Driving coils 1312 and 1322 are disposed on the movable part 1200.
[0083] In this way, when a drive signal (e.g., applying current through an external power source) is applied to the drive assembly 1300, electromagnetic induction forces are generated between the drive magnetic elements 1311 and 1321 and the drive coils 1312 and 1322, respectively, causing the movable part 1200 to move relative to the fixed part 1100, thereby achieving the desired optical effect. Furthermore, the magnetic elements 1313 and 1323 can concentrate the magnetic forces of the first drive part 1310 and the second drive part 1320, respectively, resulting in a better driving effect.
[0084] According to some embodiments of the present invention, the control component 1400 includes a first integrated circuit 1410, a second integrated circuit 1420, a first circuit component 1430, a second circuit component 1440, two sensing magnets 1451 and 1452, and a connection component 1460. Figure 5 ).
[0085] According to some embodiments of the present invention, the first integrated circuit 1410 and the second integrated circuit 1420 can each be an all-in-one integrated circuit (IC) that packages the sensing integrated circuit and the control integrated circuit in the same package. That is, the first integrated circuit 1410 and the second integrated circuit 1420 can have both sensing and control functions as needed.
[0086] However, in one embodiment of this invention, only one of the first integrated circuit 1410 and the second integrated circuit 1420 has a sensing function. This sensing element is responsible for controlling the action of the other element. The sensing element acts as the main control unit, responsible for issuing control commands, while the other element performs driving operations according to the received commands. In this way, interference between the driving signal and the sensing signal can be avoided, achieving a better driving effect.
[0087] According to some embodiments of the present invention, a first integrated circuit 1410 is disposed on a first circuit component 1430. A second integrated circuit 1420 is disposed on a second circuit component 1440. The first integrated circuit 1410 corresponds to a sensing magnet 1451. The second integrated circuit 1420 corresponds to a sensing magnet 1452.
[0088] In detail, the first integrated circuit 1410 can sense the change in the magnetic field of the sensing magnet 1451, and the second integrated circuit 1420 can sense the change in the magnetic field of the sensing magnet 1452, thereby determining the position of the first movable part 1200 relative to the fixed part 1100.
[0089] According to some embodiments of the present invention, the connecting component 1460 ( Figure 5The terminals embedded in the base 1120, and the connection assembly 1460 electrically connects the drive coils 1312 and 1322, the first circuit component 1430, and the second circuit component 1440, the details of which will be related to... Figure 5 as well as Figure 6 Detailed explanation.
[0090] According to some embodiments of the present invention, the elastic component 1500 includes four first elastic elements 1510 and two sets of second elastic elements 1521 and 1522. The first elastic elements 1510 are disposed on the movable part 1200 at one end closer to the upper cover 1110. The two ends of the second elastic elements 1521 and 1522 are respectively disposed on the base 1120 and the movable part 1200.
[0091] According to some embodiments of the present invention, an optical module (e.g., an aperture module) may be disposed on an optical element driving mechanism 1000, and the aforementioned optical module (not shown) may be electrically connected to a first elastic element 1510. A second elastic element 1521 is electrically connected to a driving coil 1312 of a first driving unit 1310, and a second elastic element 1522 is electrically connected to a driving coil 1322 of a second driving unit 1320.
[0092] According to some embodiments of the present invention, the guide element 1600 is a guide rod that guides the movable part 1200 to move relative to the fixed part 1100 on the optical axis O. The guide element 1600 is disposed between the fixed part 1100 and the movable part 1200.
[0093] According to some embodiments of the present invention, a pair of magnetic assemblies 1700 each include a magnetic element 1710 and a magnetic plate 1720. The magnetic element 1710 is disposed on the movable part 1200. The magnetic plate 1720 is disposed on the base 1120. The guiding element 1600 may include a low magnetic permeability metal material to avoid interfering with the magnetic attraction force of the magnetic assemblies 1700, and at the same time to avoid interfering with the sensing signals of the first integrated circuit 1410 and the second integrated circuit 1420.
[0094] In this way, the magnetic attraction between the magnetic element 1710 and the magnetic plate 1720 allows the movable part 1200 to rest on the two guide elements 1600, making the movement of the movable part 1200 relative to the fixed part 1100 more stable and less prone to shaking or tipping over, thereby improving the accuracy of autofocus.
[0095] According to some embodiments of the present invention, the buffer elements 1810 and 1820 may be made of materials such as silicone. The buffer element 1810 is disposed on the surface of the upper cover 1110 to buffer the impact generated by the collision between the optical element drive mechanism 1000 and an optical mechanism (not shown) that houses it, and to absorb the abnormal noise generated by the impact.
[0096] According to some embodiments of the present invention, the buffer element 1820 is disposed on the base 1120 to buffer the impact force generated by the movable part 1200 when it moves to the extreme position and the base 1120, and to absorb the abnormal noise generated by the impact.
[0097] Figure 3 Exploded views of a base 1120 and a movable part 1200 according to some embodiments of the present invention are shown. Figure 3 As shown, the base 1120 includes a body 1121, two first retaining walls 1122, two second retaining walls 1123, and two third retaining walls 1124.
