Description

Technical Field

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

[0002] As smart electronic devices continue to evolve towards thinner, lighter, and more integrated designs, achieving stable and precise motion control of optical systems within limited space has become an important development direction in related technological fields. Existing optical element driving mechanisms typically include a movable part and a fixed part. Through a driving component configured between the movable and fixed parts, the movable part can drive the optical element to move relative to the fixed part, thereby achieving functions such as focusing, image stabilization, or image compensation.

[0003] However, in existing technologies, the driving components are often concentrated on a single moving part, meaning that movements in different directions often require the joint driving of multiple structural elements, which may increase the motion load and affect driving efficiency. Furthermore, in some single-layer optical element driving mechanisms, if the moving part lacks appropriate guiding or restraining structures during movement, its direction of motion may be difficult to effectively constrain, leading to unexpected rotation or offset during movement and affecting the stability of the overall motion behavior. Therefore, how to reduce the motion load and improve the motion stability of the moving part while balancing structural configuration and degrees of freedom remains a challenge that needs further improvement in this technical field. 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, and a first driving assembly. The first movable part is used to connect an optical element having an optical axis. The first movable part is movable relative to the fixed part. The first driving assembly is used to drive the first movable part to move relative to the fixed part.

[0006] In some embodiments of this disclosure, the optical element driving mechanism further includes a first connecting component, the first movable part being movable relative to the fixed part via the first connecting component, the first connecting component including a first connecting element, the first connecting element being located between the first movable part and the fixed part, the first connecting element being movable relative to the fixed part, and the first connecting element being movable relative to the first movable part.

[0007] The beneficial effects of this disclosure are that by distributing the drive structure to different moving parts, each moving part can be driven independently according to its direction of motion. In some motion situations, the weight of the components that need to be driven can be reduced, thereby helping to reduce motion load and improve drive efficiency. Furthermore, by limiting the direction of motion of the moving parts through the guide structure, the rotation or offset that may occur during the movement of the moving parts can be suppressed, further improving the overall motion stability and reliability.

[0029] According to some embodiments of this disclosure, the first movable part 1200 is movable relative to the fixed part 1100 via the first connecting assembly 1400. The first connecting assembly 1400 includes a first connecting element 1410, three first intermediate elements 1420, and three second intermediate elements 1430.

[0030] According to some embodiments of this disclosure, a first connecting element 1410 is located between a first movable portion 1200 and a base 1120 of a fixed portion 1100. The first connecting element 1410 is movable relative to the fixed portion 1100, and the first movable portion 1200 is movable relative to the first connecting element 1410.

[0033] According to some embodiments of this disclosure, the second connecting element 1510 and the third connecting element 1520 have elongated structures and extend along the optical axis O. On the optical axis O, the maximum dimension of the second connecting element 1510 differs from the maximum dimension of the third connecting element 1520.

[0034] According to some embodiments of this disclosure, when viewed along the optical axis O, the second connecting element 1510 and the third connecting element 1520 are located near the second side 1112 of the housing 1110, and the second connecting element 1510 is closer to the first side than the third connecting element 1520. On the optical axis O, the maximum size of the second connecting element 1510 is smaller than the maximum size of the third connecting element 1520.

[0035] According to some embodiments of this disclosure, a first drive assembly 1600 is used to drive a first movable part 1200 to move relative to a fixed part 1100. The first drive assembly 1600 includes a first drive part 1610 and a second drive part 1620. The first drive part 1610 drives a first connecting element 1410 to move in the X-axis direction, thereby causing the first connecting element 1410 to move the first movable part 1200 and the second movable part 1300 in the X-axis direction. The second drive part 1620 drives the first movable part 1200 to move in the Y-axis direction, thereby causing the first movable part 1200 to move the second movable part 1300 in the Y-axis direction.

[0036] According to some embodiments of this disclosure, the first driving unit 1610 includes a first magnetic element 1611, two first coils 1612, and a sensing element 1613.

[0037] According to some embodiments of this disclosure, the first magnetic element 1611 corresponds to the first coil 1612. Specifically, when a driving signal is applied to the first coil 1612 (e.g., current is applied through an external power source), an electromagnetic induction force is generated between the first magnetic element 1611 and the first coil 1612, which in turn drives the first connecting element 1410 to move along the X-axis, thereby driving the optical element to the desired position.

[0038] According to some embodiments of this disclosure, a sensing element 1613 is disposed on a base 1120. The sensing element 1613 is used to detect changes in the magnetic field generated by the first magnetic element 1611 and convert the changes in the magnetic field into corresponding electrical signals to realize closed-loop control of the optical element drive mechanism 1000.

[0039] According to some embodiments of this disclosure, the second driving unit 1620 includes a second magnetic element 1621, two second coils 1622, a sensing element 1623, and a magnetically conductive element 1624.

[0040] According to some embodiments of this disclosure, the second magnetic element 1621 corresponds to the second coil 1622. When a driving signal is applied to the second coil 1622 (e.g., current is applied through an external power source), an electromagnetic induction force is generated between the second magnetic element 1621 and the second coil 1622, which in turn drives the first movable part 1200 to move on the Y-axis to drive the optical element to the desired position.

[0041] According to some embodiments of this disclosure, a sensing element 1623 is disposed on a base 1120. The sensing element 1623 is used to detect changes in the magnetic field generated by the second magnetic element 1621 and convert the changes in the magnetic field into corresponding electrical signals to realize closed-loop control of the optical element drive mechanism 1000.

The magnetically conductive element 1624 has high magnetic permeability (e.g., iron, silicon steel sheet, 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.

[0043] According to some embodiments of this disclosure, the second drive assembly 1700 is used to drive the second movable part 1300 to move relative to the fixed part 1100. The second drive assembly 1700 includes a third magnetic element 1710, a third coil 1720, a sensing element 1730, and a magnetically conductive element 1740. The third magnetic element 1710 is disposed on the first movable part 1200. The third coil 1720 is disposed on the second movable part 1300.

[0044] According to some embodiments of this disclosure, the third magnetic element 1710 corresponds to the third coil 1720. Specifically, when a driving signal is applied to the third coil 1720 (e.g., current is applied through an external power source), an electromagnetic induction force is generated between the third magnetic element 1710 and the third coil 1720, which in turn drives the second movable part 1300 to move on the optical axis O, thereby driving the optical element to the desired position.

[0045] According to some embodiments of this disclosure, a sensing element 1730 is disposed on the second movable part 1300. The sensing element 1730 is used to detect changes in the magnetic field generated by the third magnetic element 1710 and convert the changes in the magnetic field into corresponding electrical signals to realize closed-loop control of the optical element drive mechanism 1000.

[0046] According to some embodiments of this disclosure, a magnetically conductive element 1740 is disposed on the first movable portion 1200. The magnetically conductive element 1740 has high magnetic permeability (e.g., iron, silicon steel sheet, 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.

The thickness of the second circuit assembly 1820 is greater than 0.02 mm. When viewed along the optical axis O, the second circuit assembly 1820 is located on the third side 1113 of the fixing portion 1100, which has a polygonal structure.

The fourth circuit assembly 1840 is electrically connected to the third circuit assembly 1830.

[0051] According to some embodiments of this disclosure, the fifth circuit assembly 1850 may be a flexible printed circuit board. The fifth circuit assembly 1850 is disposed on the second movable portion 1300. The third coil 1720 and the third sensing element 1730 are electrically connected to the fifth circuit assembly 1850.

[0052] According to some embodiments of this disclosure, the stabilizing component 1900 is used to generate a stabilizing force to bring the first movable part 1200 closer to the base 1120 of the fixed part 1100. The stabilizing component 1900 includes a first stabilizing element, a second stabilizing element 1910, a third stabilizing element, a fourth stabilizing element 1920, and a fifth stabilizing element 1930.

[0053] exist Figure 2 The image shows the second stabilizing element 1910, the fourth stabilizing element 1920, and the fifth stabilizing element 1930 in the stabilizing component 1900. The settings of the first and third stabilizing elements will be related to... Figure 6A as well as Figure 6B Detailed explanation.

[0054] Figure 3 An exploded perspective view of a first connecting element 1410 and a first magnetic element 1611 according to some embodiments of the present disclosure is shown. Figure 3 As shown, the first connecting element 1410 includes a first substrate 1411 and a second substrate 1412.

The second recessed structure 1412-1 corresponds to at least a portion of the first movable portion 1200. Figure 2 ).

[0056] According to some embodiments of this disclosure, a first base surface 1411-2 of the first recessed structure 1411-1 faces the first magnetic element 1611 of the first driving assembly 1600, and a second base surface 1412-2 of the second recessed structure 1412-1 faces the first movable portion 1200. Figure 2 The first substrate surface 1411-2 and the second substrate surface 1412-2 face opposite directions. The first substrate surface 1411-2 and the second substrate surface 1412-2 are perpendicular to the optical axis O.

[0057] According to some embodiments of this disclosure, on the optical axis O, the first intermediate element 1420 is closer to the first substrate surface 1411-2 than the second substrate surface 1412-2. On the optical axis O, the second intermediate element 1430 is closer to the second substrate surface 1412-2 than the first substrate surface 1411-2.

When viewed along a direction parallel to the first observation direction (parallel to the Y-axis), the second substrate surface 1412-2 does not overlap with the first substrate 1411.

[0059] For now, refer to Figure 2 as well as Figure 3 When viewed along the optical axis O, the first substrate 1411 is located near the first side 1111 of the outer casing 1110. When viewed along the optical axis O, the second substrate 1412 is located near the second side 1112 of the outer casing 1110.

[0061] In this way, by making the second connecting element 1510 and the third connecting element 1520 have different lengths, and by placing the shorter connecting element above the first connecting element 1410 to avoid the first connecting element 1410, interference with the first connecting element 1410 can be avoided while ensuring the normal operation of the guiding structure, thereby improving the miniaturization of the overall structure configuration and the stability of the movement process.

When viewed along the optical axis O, the third stabilizing element (i.e., Figure 2 The third magnetic element 1710 is located on the second side 1112 of the fixing part 1100. In this embodiment, the first stabilizing element is a magnet, and the third stabilizing element is a magnet.

[0069] like Figure 2 As shown, the fifth stabilizing element 1930 is fixedly disposed in the first movable portion 1200. The fifth stabilizing element 1930 is used to generate a third stabilizing force. When viewed along the optical axis O, the fifth stabilizing element 1930 is located on the first side 1111 of the fixed portion 1100. The fifth stabilizing element 1930 and the first stabilizing element (i.e., the first magnetic element 1611) generate the third stabilizing force.

When viewed along the optical axis O, the second stop element 1320 is closer to the second connecting assembly 1500 than the first stop element 1310.

[0078] In summary, by distributing the drive structure to different moving parts, this disclosure enables each moving part to be driven independently according to its direction of motion. In some motion scenarios, this reduces the weight of the components that need to be driven, thereby helping to reduce motion load and improve drive efficiency. Furthermore, by limiting the direction of motion of the moving parts through the guide structure, the rotation or offset that may occur during the movement of the moving parts can be suppressed, further improving the overall motion stability and reliability.
