Description

Technical Field

[0001] This invention relates to an optical element driving mechanism, and more particularly to an optical element driving mechanism including a connecting component. Background Technology

[0002] As smart electronic devices continue to evolve, the integration of photography and video recording functions is becoming increasingly common, trending towards smaller, thinner designs and higher module integration. To meet the demands of applications such as image quality enhancement and optical image stabilization, many optical element drive mechanisms are now adopting multiple independent moving parts and multi-axis drive designs to achieve more precise image adjustment. These optical element drive mechanisms typically contain two or more moving parts, which are connected to each axis drive assembly via connecting elements, allowing the optical element to compensate and adjust along multiple axes.

[0003] However, in existing technologies, optical component driving mechanisms often lack proper decoupling designs, leading to interference between moving parts during movement, which in turn affects the stability and control accuracy of the module. Existing structures also lack designs that simultaneously provide guidance and tolerance absorption, resulting in uneven overall movement. Therefore, how to achieve decoupled movement between multiple axes while ensuring the stability and support of connecting components is a pressing technical challenge. Summary of the Invention

[0004] The purpose of this invention is to provide an optical element driving mechanism to solve at least one of the above-mentioned problems.

[0005] This invention provides an optical element driving mechanism, which includes a first movable part, a fixed part, a driving assembly, and a connecting assembly. The first movable part is used to connect to an optical element. The first movable part is movable relative to the fixed part. The driving assembly is used to drive the first movable part to move relative to the fixed part. The first movable part is movable relative to the fixed part via the connecting assembly.

[0006] According to some embodiments of this disclosure, the connecting assembly includes a first connecting element and a second connecting element. A first movable portion is movable relative to a fixed portion via the first connecting element. The first movable portion is also movable relative to the fixed portion via the second connecting element. Both the first and second connecting elements are movable relative to the fixed portion.

[0007] The beneficial effect of this invention is that by using V-shaped grooves to form a tight-fit structure in some corresponding parts and U-shaped grooves to form a loose-fit structure in others, the stability of guidance and positioning and the degrees of freedom required for movement can be balanced. This design can effectively achieve decoupling control between axes, avoid interference and jamming, and improve the smoothness of movement and positioning accuracy of the optical element drive mechanism.

[0106] According to some embodiments of this disclosure, the first movable part 1200 is movable relative to the fixed part 1100 via the connecting assembly 1500. The connecting assembly 1500 includes a first connecting element 1510, a second connecting element 1520, a first connecting part 1530-1, a second connecting part 1530-2, a third connecting part 1530-3, a fourth connecting part 1530-4, a fifth connecting part 1530-5, a sixth connecting part 1530-6, a seventh connecting part 1530-7, an eighth connecting part 1530-8, a ninth connecting part 1530-9, and a tenth connecting part 1530-10.

[0107] According to some embodiments of this disclosure, the first connecting element 1510 is movable relative to the fixed portion 1100, and the second connecting element 1520 is movable relative to the fixed portion 1100. The first connecting element 1510 is movable relative to the second movable portion 1300, and the second connecting element 1520 is movable relative to the second movable portion 1300. The first movable portion 1200 is movable relative to the fixed portion 1100 via the first connecting element 1510. The first movable portion 1200 is movable relative to the fixed portion 1100 via the second connecting element 1520.

[0108] According to some embodiments of this disclosure, the first connecting portion 1530-1 and the second connecting portion 1530-2 may be ball bearings disposed between the first movable portion 1200 and the first connecting element 1510. The third connecting portion 1530-3 and the fourth connecting portion 1530-4 may be ball bearings disposed between the first movable portion 1200 and the second connecting element 1520.

[0109] According to some embodiments of this disclosure, the fifth connecting portion 1530-5, the sixth connecting portion 1530-6, and the tenth connecting portion 1530-10 may be ball bearings disposed between the second movable portion 1300 and the first connecting element 1510. The seventh connecting portion 1530-7, the eighth connecting portion 1530-8, and the ninth connecting portion 1530-9 may be ball bearings disposed between the second movable portion 1300 and the second connecting element 1520.

[0110] According to some embodiments of this disclosure, the first movable part 1200 is movable relative to the first connecting element 1510 via the first connecting part 1530-1 and the second connecting part 1530-2. The first movable part 1200 is movable relative to the second connecting element 1520 via the third connecting part 1530-3 and the fourth connecting part 1530-4.

[0111] According to some embodiments of this disclosure, the magnetic element 1411 of the first driving unit 1410 is disposed on the first connecting element 1510, and the coil 1412 is disposed on the circuit component 1130. The magnetic element 1421 of the second driving unit 1420 is disposed on the second connecting element 1520, and the coil 1422 is disposed on the circuit component 1130.

[0112] According to some embodiments of this disclosure, the magnetic elements 1413 and 1423 have high magnetic permeability (e.g., iron, silicon steel sheets, etc.), which can effectively guide the path of magnetic field lines, concentrate the magnetic flux in the magnetic circuit formed by the coil and the magnet, increase the magnetic field strength, and thus increase the magnetic force.

[0113] The magnetic element 1411 corresponds to the coil 1412. In detail, when a driving signal is applied to the coil 1412 (for example, by applying current through an external power source), an electromagnetic induction force is generated between the magnetic element 1411 and the coil 1412, which in turn drives the first movable part 1200 to move on the second axis D2, thereby driving the optical element 2000 to the desired position.

[0114] Similarly, the magnetic element 1421 corresponds to the coil 1422. When a driving signal is applied to the coil 1422 (e.g., current is applied through an external power source), an electromagnetic induction force is generated between the magnetic element 1421 and the coil 1422, which in turn drives the first movable part 1200 to move on the third axis D3, thereby driving the optical element 2000 to the desired position.

[0115] According to some embodiments of this disclosure, sensing elements 1414 and 1424 are respectively disposed on circuit component 1130. Sensing elements 1414 and 1424 are used to detect changes in magnetic fields generated by magnetic elements 1411 and 1421, respectively, and convert the changes in magnetic fields into corresponding electrical signals to realize closed-loop control of optical element driving mechanism 1000.

[0116] According to some embodiments of this disclosure, the magnetic element 1431 of the third drive unit 1430 is disposed on the second movable part 1300, and the coil 1432 is disposed on the base 1120. The magnetic conductive element 1433 is disposed on the circuit member 1130, so that the magnetic attraction generated between the magnetic conductive element 1433 and the magnetic element 1431 causes the second movable part 1300 to rest against the side of the fixed part 1100 where the guide element 1600 is disposed.

[0117] The magnetic element 1431 corresponds to the coil 1432. In detail, when a driving signal is applied to the coil 1432 (for example, by applying current through an external power source), an electromagnetic induction force is generated between the magnetic element 1431 and the coil 1432, which in turn drives the second movable part 1300 to move on the first axis D1, thereby driving the optical element 2000 to the desired position.

[0118] According to some embodiments of this disclosure, a sensing element 1434 is disposed on a circuit component 1130. The sensing element 1434 is used to detect changes in the magnetic field generated by the magnetic element 1431 and convert the changes in the magnetic field into corresponding electrical signals to realize closed-loop control of the optical element drive mechanism 1000.

[0119] According to some embodiments of this disclosure, the guide element 1600 may be a guide rod disposed near the third drive unit 1430. The guide element 1600 is positioned between the base 1120 and the second movable part 1300 to guide the movement of the second movable part 1300 relative to the fixed part 1100.

[0120] According to some embodiments of this disclosure, the stabilizing component 1700 is used to apply a stabilizing force to the first movable part 1200, enabling the first movable part 1200 to continuously contact the connecting component 1500. The stabilizing component 1700 includes a first stabilizing part 1710 and a second stabilizing part 1720.

[0121] According to some embodiments of this disclosure, the first stabilizing unit 1710 includes a first stabilizing element 1711. Figure 3 A second stabilizing element 1712 and a third stabilizing element 1713 Figure 5 The second stabilizing unit 1720 includes a first stabilizing element 1721. Figure 3 A second stabilizing element 1722 and a third stabilizing element 1723 Figure 5 The details will be about Figure 3 as well as Figure 5 Detailed explanation.

[0123] like Figure 3 As shown, the first stabilizing element 1711 of the first stabilizing part 1710 and the first stabilizing element 1721 of the second stabilizing part 1720 are fixedly disposed in the first movable part 1200.

Figure 4 As shown, the second stabilizing element 1712 of the first stabilizing part 1710 and the second stabilizing element 1722 of the second stabilizing part 1720 are fixedly disposed in the second moving part 1300.

[0125] According to some embodiments of this disclosure, the second stabilizing elements 1712 and 1722 are disposed on the second movable portion 1300 and are therefore movable relative to the fixed portion 1100. Due to the first movable portion 1200 ( Figure 3 The first stabilizing elements 1711 and 1721 can move relative to the second movable part 1300. Figure 3 It can move relative to the second stabilizing elements 1712 and 1722.

(See figure) Figure 6 As shown, when viewed along the first axis D1, the first stabilizing element 1711, the second stabilizing element 1712, and the third stabilizing element 1713 of the first stabilizing part 1710 at least partially overlap.

[0129] According to some embodiments of this disclosure, the first stabilizing element 1710 is used to generate a first stabilizing force. Specifically, the first stabilizing force is generated between the second stabilizing element 1712 and the first stabilizing element 1711, and between the second stabilizing element 1712 and the third stabilizing element 1713 of the first stabilizing element 1710.

[0130] Although not in Figure 6 As shown, similarly, the second stabilizing part 1720 is used to generate a second stabilizing force. Specifically, the second stabilizing element 1722 of the second stabilizing part 1720 (… Figure 4 ) and the first stabilizing element 1721 ( Figure 3 Between the second stabilizing element 1722 and the third stabilizing element 1723 Figure 5 A second stabilizing force is generated between them.

[0132] like Figure 7 As shown, a stabilizing force F consists of at least a first stabilizing force and a second stabilizing force (in this embodiment, the stabilizing force F can be regarded as the resultant force of the first stabilizing force and the second stabilizing force). A first imaginary plane (which is parallel to the plane formed by the second axis D2 and the third axis D3) passes through the first connecting part 1530-1, the second connecting part 1530-2, and the third connecting part 1530-3.

[0133] like Figure 7 As shown, when viewed along a direction perpendicular to the first imaginary plane (e.g., along the positive and negative first axes D1), the point of application of the stabilizing force F is located at an imaginary position. When viewed along a direction perpendicular to the first imaginary plane (e.g., along the positive and negative first axes D1), the aforementioned imaginary position (the point of application of the stabilizing force F) is located within a first imaginary triangle T1 formed by the first connecting portion 1530-1, the second connecting portion 1530-2, and the third connecting portion 1530-3. The direction of the stabilizing force F is not parallel to the first imaginary plane (the first imaginary plane is parallel to the plane formed by the second axis D2 and the third axis D3).

[0134] Please refer to this as well. Figure 4 as well as Figure 7 The second connecting element 1520 can move relative to the fixed part 1100 via the fifth connecting part 1530-5, the sixth connecting part 1530-6, and the tenth connecting part 1530-10. The first connecting element 1510 can move relative to the fixed part 1100 via the seventh connecting part 1530-7, the eighth connecting part 1530-8, and the ninth connecting part 1530-9.

[0135] like Figure 4 As shown, a second imaginary plane (parallel to the plane formed by the second axis D2 and the third axis D3) is formed by the fifth connecting part 1530-5, the seventh connecting part 1530-7 and the eighth connecting part 1530-8.

Figure 7 The first imaginary plane described herein (which is formed by the first connecting portion 1530-1, the second connecting portion 1530-2, and the third connecting portion 1530-3) and Figure 4The second imaginary plane (which is formed by the fifth connecting part 1530-5, the seventh connecting part 1530-7 and the eighth connecting part 1530-8) is parallel to each other but does not overlap.

[0137] like Figure 4 As shown, when viewed along the direction perpendicular to the second imaginary plane (e.g., along the positive and negative first axis D1), the aforementioned imaginary position (the point of application of the stabilizing force F) is located within a second imaginary triangle T2 formed by the fifth connecting part 1530-5, the seventh connecting part 1530-7, and the eighth connecting part 1530-8.

[0138] Please refer to this as well. Figure 4 as well as Figure 7 When viewed along a direction perpendicular to the second imaginary plane (e.g., along the positive and negative first axis D1), the first imaginary triangle T1 and the second imaginary triangle T2 have non-overlapping portions.

[0139] like Figure 4 As shown, the fixing part 1100 has a first corner 1100-1, a second corner 1100-2, a third corner 1100-3, and a fourth corner 1100-4. The third corner 1100-3 is not adjacent to the first corner 1100-1, and the fourth corner 1100-4 is not adjacent to the second corner 1100-2. Specifically, the third corner 1100-3 and the first corner 1100-1 are located diagonally opposite each other, and the fourth corner 1100-4 and the second corner 1100-2 are located diagonally opposite each other.

[0162] In summary, the optical element driving mechanism of this disclosure provides the required degrees of freedom of motion by providing connecting portions (e.g., ball bearings) above and below the first connecting element and the second connecting element, respectively. With this configuration, when the first connecting element is driven to move the first movable part in a specific direction, the second connecting element can decouple from the movement of the first movable part under the degree of freedom provided by the connecting portions, thereby maintaining its original position without being moved, and vice versa. This design effectively improves the independence and accuracy of multi-axis drive control, avoids interference between different drive paths, and helps to achieve stable and efficient optical element positioning control, thereby improving the overall module's operational performance and reliability.

[0163] By employing V-shaped grooves to form a tight fit in some corresponding parts and U-shaped grooves to form a loose fit in others, the design balances the stability of guidance and positioning with the degrees of freedom required for movement. This design effectively achieves decoupling control between different axes, avoiding interference and jamming, and improving the smoothness of movement and positioning accuracy of the optical element drive mechanism.

[0164] Furthermore, this disclosure provides a stabilizing force between the first movable part, the second movable part, and the connecting assembly by setting up a first stabilizing part and a second stabilizing part, thereby further preventing the first connecting element and the second connecting element from tipping over during movement. This design helps to improve the mechanical stability of the overall structure and ensures the balance and reliability of the optical element drive mechanism during operation.
