[0001] This utility model relates to an optical element driving mechanism. More specifically, it relates to an optical element driving mechanism having a positioning component structure. Background Technology

[0002] With the development of technology, many electronic devices today (such as computers or tablets) have the function of taking pictures or recording videos. As the use of these electronic devices becomes more and more widespread, in addition to developing more stable and better optical quality, they are also moving towards convenient and thinner designs to provide users with more choices.

[0003] However, when optical elements with long focal lengths (such as lenses) are incorporated into the aforementioned electronic devices, it increases the thickness and weight of the devices, which is detrimental to their slimness and stability. Furthermore, due to different imaging requirements, these electronic devices need to have functions such as optical image stabilization, focal length adjustment, and light intake control.

[0004] Therefore, designing optical systems that enable electronic devices to be thinner and lighter, more stable, and more compatible, capable of supporting more optical components, bearing greater weight, and reducing the number of parts used, has become an important issue. Utility Model Content

[0091] This utility model relates to an optical element driving mechanism, which has multiple moving parts, multiple driving components, a positioning component, and a stabilizing component.

The multiple driving components drive the multiple moving parts and optical elements to move, thereby adjusting the photographic imaging of the optical element driving mechanism to adapt to different photographic needs.

[0092] Please refer to the following: Figures 1A to 2 . Figure 1A A perspective view of an example optical element driving mechanism 1 is provided to illustrate certain features of this utility model.

[0093] Figure 1B To illustrate certain features of this invention, a perspective view of the optical element drive mechanism 1 is provided, wherein the housing 510 is shown in dashed lines for illustrative purposes.

[0094] Figure 2 An exploded perspective view of an example optical element drive mechanism 1 is provided to illustrate certain features of this utility model.

[0095] The optical element driving mechanism 1 includes a first movable part 100, a second movable part 200, a first driving component 300, a second driving component 400, a fixing part 500, a positioning component 600, a connecting component 700, a guiding component 800, and a stabilizing component 900.

[0096] The first movable part 100 is used to connect an optical element 10. The first movable part 100 is movable relative to the second movable part 200. The first driving assembly 300 is used to drive the first movable part 100 to move. The second driving assembly 400 is used to drive the second movable part 200 and the first movable part 100 to move relative to the fixed part 500. The positioning assembly 600 is fixedly connected to the first driving assembly 300 and the second movable part 200. The guiding assembly 800 guides the movement of the first movable part 100 relative to the second movable part 200. The stabilizing assembly 900 generates an adsorption force on the second movable part 200 towards the fixed part 500, thereby stabilizing the longitudinal structure of the optical element driving mechanism 1.

[0097] The optical element 10 can be a lens or other element capable of receiving external light. Incident light from the outside passes through the optical element drive mechanism 1 along the incident axis O1 and reaches the optical element 10. The optical element 10 is mounted on the support 110 of the first movable part 100 of the optical element drive mechanism 1, and achieves the functions of autofocus (AF) and optical image stabilization (OIS) through the optical element drive mechanism 1.

[0098] The first movable part 100 includes a support 110 and a spring 120. The support 110 houses the magnet 310 of the first drive assembly 300 and is connected to the optical element 10. The spring 120 connects the support 110 to the frame 210 of the second movable part 200. When the first movable part 100 is driven by the first drive assembly 300, causing the support 110 to move relative to the frame 210, the spring 120 flexibly connects the first movable part 100 and the second movable part 200.

[0099] The second movable part 200 includes a frame 210, a top cover 220, and a spring 230. The frame 210 is movable relative to the first movable part 100. The top cover 220 is fixedly connected to the frame 210 via a first connecting element 710 of the connecting assembly 700 and is movable relative to the first movable part 100. The spring 230 connects the frame 210 to the base 520 of the fixed part 500. When the second movable part 200 is driven by the second driving assembly 400, causing the frame 210 to move relative to the base 520, the spring 230 flexibly connects the second movable part 200 to the fixed part 500.

[0100] The first drive assembly 300 includes one or more magnets 310 and one or more coils 320. The magnets 310 are disposed on the support 110 of the first movable part 100. The coils 320 are disposed on the frame 210 of the second movable part 200 via a positioning assembly 600 (hereinafter referred to as relative to the positioning assembly 600 and...). Figures 3A to 8 (Detailed explanation).

[0101] The electromagnetic driving force generated between the magnet 310 and the coil 320 causes the magnet 310 to move relative to the coil 320 along the incident axis O1. The movement of the magnet 310 drives the support 110 of the first movable part 100 to move, thus causing the support 110 of the first movable part 100 to move relative to the coil 320 through the frame 210 of the second movable part 200 on which the positioning assembly 600 is disposed.

[0102] Therefore, the first movable part 100 moves relative to the second movable part 200, and the first movable part 100 drives the optical element 10 to move. Thus, the electromagnetic driving force generated between the magnetic element 310 and the coil 320 can drive the first movable part 100 to move the optical element 10 relative to the second movable part 200 along the incident axis O1, thereby realizing the focusing function.

[0103] The second drive assembly 400 includes a plurality of first drive units 410, a plurality of second drive units 420, and a plurality of drive connection units 430. The second drive assembly 400 drives the second movable unit 200 to move in a first dimension (perpendicular to the incident axis O1 of the incident light, i.e., the direction of the X and Y axes). The first drive units 410 are fixedly disposed on the frame 210 of the second movable unit 200. The second drive units 420 are fixedly disposed on the base 520 of the fixed unit 500. The drive connection units 430 electrically connect the first drive units 410 and the second drive units 420, so the second movable unit 200 is connected to the fixed unit 500 through the first drive units 410 and the second drive units 420.

[0104] In this embodiment, the drive connection 430 is made of, for example, shape memory alloy (SMA) material, and its length can be changed by applying a drive signal (e.g., current) to it via an external power source (not shown).

[0105] For example, when a drive signal reaches the drive connection 430 via the first drive unit 410 and the second drive unit 420, causing the drive connection 430 to heat up, the drive connection 430 can deform and lengthen or shorten; when the drive signal is stopped, the drive connection 430 can return to its original length. In other words, by applying an appropriate drive signal, the length of the drive connection 430 can be controlled so that the drive connection 430 drives the frame 210 of the second movable part 200 to move relative to the base 520 of the fixed part 500, thereby driving the first movable part 100 and the optical element 10 to move, so that the optical element drive mechanism 1 has the function of anti-shake or tremor compensation.

[0106] In some embodiments, the first driving part 410 and the second driving part 420 may be composed of, for example, a spring or a fixing plate. The first driving part 410 and the second driving part 420 are electrically connected to a first external circuit, for example, to the circuit board 540 of the fixing part 500.

[0107] The fixing part 500 includes a housing 510, a base 520, a base plate 530, and a circuit board 540. The housing 510 and the base plate 530 are fixedly connected to form a receiving space, in which at least part of the components of the optical element driving mechanism 1 are located. The incident axis O1 passes through this receiving space. The base 520 is fixedly connected to the base plate 530, and the circuit board 540 is attached to the base 520.

[0108] Please refer to the following: Figure 3A as well as Figure 3B . Figure 3A To illustrate certain features of this utility model, a front perspective view of the fastener 610 of the positioning assembly 600 of the example optical element drive mechanism 1 is provided.

[0109] Figure 3B To illustrate certain features of this utility model, a rear perspective view of the fastener 610 and the receiver 620 of the positioning assembly 600 of the example optical element drive mechanism 1 is provided.

[0110] The positioning assembly 600 includes a fastener 610, a positioning part 612, a fastener engaging part 614, a receiving part 620, a reinforcing element 630, and a plurality of reinforcing parts 632. The reinforcing element 630 is fixed to the fastener 610, and the fastener 610 is engaged with the receiving part 620.

[0111] Fastener 610, positioning part 612, fastener engaging part 614, and receiving part 620 may be made of plastic. Fastener 610 has a fastener surface 611 (see...) Figure 3B The positioning portion 612 protrudes from the fastener 610. The coil 320 of the first drive assembly 300 can be fixed to the positioning portion 612. More specifically, the coil 320 is wound around the positioning portion 612. A fastener engaging portion 614 is formed on the fastener 610. The fastener engaging portion 614 has an engaging surface 615 (see...). Figure 3B The engaging surface 615 is not parallel to the fastener surface 611.

[0112] The receiver 620 has a receiver surface 621 (see below) Figure 5 The fastener 610 is fixedly connected to the receiver 620 via the first connecting element 710 of the connecting assembly 700. The receiver engagement portion 622 corresponds to the fastener engagement portion 614.

[0113] In this embodiment, the receiver 620 is located in the frame 210 of the second movable part 200, such that the coil 320 is ultimately received in the frame 210 (as will be referred to below relative to...). Figures 5 to 8 (as described above). Therefore, when the magnet 310 drives the first movable part 100 to move, it moves relative to the frame 210 where the receiving part 620 receiving the fastener 610 wound with the coil 320 is located.

[0114] In other embodiments, the receiver 620 may be positioned at other suitable locations, such as a suitable location of the fixing portion 500, so that the magnet 310 can move relative to the fixing portion 500 where the coil 320 is located.

[0115] Please refer to the following. Figure 4 . Figure 4 To illustrate certain features of this utility model, a perspective view of the reinforcing element 630 of the positioning assembly 600 of the example optical element drive mechanism 1 is provided.

[0116] The reinforcing element 630 is made of metal and is fixedly attached to the fastener 610. In this embodiment, the reinforcing element 630 and the fastener 610 are made of different materials. The reinforcing portion 632 has a protruding structure formed on the reinforcing element 630 and disposed on the positioning portion 612. More specifically, the reinforcing portion 632 extends and is embedded in the positioning portion 612 to reinforce the structure of the positioning portion 612.

[0117] Please refer to the following: Figures 5 to 8 This section describes the process of combining the positioning component 600 with the coil 320.

[0118] First see Figure 5 . Figure 5 To illustrate certain features of this utility model, a front perspective view of the combination of the coil 320 of the first drive assembly 300 of the example optical element drive mechanism 1 and the fastener 610 of the positioning assembly 600 is shown, wherein the second connecting element 720 of the connecting assembly 700 is indicated by dashed lines.

[0119] Fastener 610 is formed on reinforcing element 630, such that positioning portion 612 covers reinforcing portion 632. Coil 320 is attached to fastener 610 via second connecting element 720 in the direction of arrow A1; more specifically, coil 320 is attached to positioning portion 612. Thus, coil 320 connects positioning portion 612 and reinforcing element 630 via second connecting element 720.

[0120] Please see below. Figure 6A . Figure 6A To illustrate certain features of this utility model, a front perspective view of the combined coil 320 and fastener 610 of the example optical element driving mechanism 1 is provided. The combined coil 320 and fastener 610 are shown as follows... Figure 6A As shown, coil 320 is wound around positioning part 612. The process then proceeds to... Figure 6B .

[0121] Please see Figure 6B . Figure 6B To illustrate certain features of this utility model, a rear perspective view of the coil 320 of the example optical element drive mechanism 1 and the combination of the fastener 610 and the receiver 620 is provided.

[0122] The assembled coil 320 and fastener 610 are attached to the receiver 620 in the direction of arrow A2. More specifically, the receiver engagement portion 614 is attached to the receiver engagement portion 622 of the receiver 620. The receiver engagement portion 614 contacts the receiver engagement portion 622. The engagement surface 615 of the receiver engagement portion 614 therefore contacts the receiver engagement portion 622. And the fastener surface 611 therefore engages with the receiver surface (shown in...). Figure 5 ).

The first connecting element 710 directly contacts the fastener 610 and the receiving portion 620. When viewed along the direction parallel to the engaging surface 615 (i.e., along...), Figure 10 (From the perspective of observation), the receiving part 622 is at least partially located between the fastener surface 611 and the engaging part surface 615.

[0129] The first connecting element 710, the second connecting element 720, and the third connecting element 730 are made of resin. The fourth connecting element 740 and the fifth connecting element 750 may be made of rubber or silicone.

[0130] Fastener 610 is connected to receiver 620 via first connecting element 710. Coil 320 is fixedly connected to reinforcing element 630 via second connecting element 720. Second connecting element 720 directly contacts positioning part 612, coil 320 and reinforcing element 630.

[0131] The coil 320 is fixedly connected to the receiver 620 via a third connecting element 730. The third connecting element 730 directly contacts the reinforcing element 630, the coil 320, and the receiver 620.

[0132] The fourth connecting element 740 is located in the first movable part 100 and provides cushioning relative to peripheral elements (e.g., the top cover 220 of the second movable part 200) when the first movable part 100 moves.

[0133] The fifth connecting element 750 is located in the second movable part 200 and provides cushioning relative to peripheral elements (e.g., the housing 510 of the fixed part 500) when the second movable part 200 moves.

[0134] The guide assembly 800 includes a plurality of guide rods 810 and a plurality of third magnetic elements 820. The guide rods 810 connect the first movable part 100 and the second movable part 200. The third magnetic elements 820 correspond to the guide rods 810. The guide rods 810 and the third magnetic elements 820 guide the movement of the first movable part 100 relative to the second movable part 200.

[0135] This embodiment includes two guide rods 810 and two third magnetic elements 820. The guide rods 810 are movably connected to the support 110 of the first movable part 100 and the frame 210 of the second movable part 200. The guide rods 810 are disposed in the grooves of the support 110 and the grooves of the frame 210, approximately at two opposite corners of the four corners of the optical element driving mechanism 1.

[0136] When the first movable part 100 is driven by the first drive assembly 300, the guide rod 810 moves between the support 110 and the frame 210. The groove in the support 110 allows the guide rod 810 to slide in the direction of the incident axis O1 between itself and the frame 210. Therefore, the guide rod 810 allows the second first movable part 100 to move smoothly relative to the frame 210.

[0137] Please refer to the following: Figure 2 as well as Figure 11 . Figure 11 To illustrate certain features of this invention, an example optical element drive mechanism 1 is shown in cross-sectional view along line L3 of FIG1.

[0138] The stabilizing component 900 includes a plurality of first magnetic elements 910 and a plurality of second magnetic elements 920. The first magnetic elements 910 may be magnetic components such as magnets or magnetic conductors; in this embodiment, the first magnetic element 910 is a magnet. Each first magnetic element 910 has a first magnetic element surface 911 and a second magnetic element surface 912.

[0139] The second magnetic element 920 can be a magnetic element such as a magnet or a magnetic conductor. In this embodiment, the second magnetic element 920 is a magnetic sheet. The second magnetic element 920 corresponds to the first magnetic element 910. An attractive force is generated between the first magnetic element 910 and the second magnetic element 920, causing the first magnetic element 910 and the second magnetic element 920 to move closer to each other.

[0140] In this embodiment, the first magnetic element 910 is located in the frame 210 of the second movable part 200, while the second magnetic element 920 is located in the base 520 of the fixed part 500. The frame 210 of the second movable part 200 has an angle 212 to fix the first magnetic element 910. Therefore, the attraction between the first magnetic element 910 and the second magnetic element 920 brings the frame 210 of the second movable part 200 and the base 520 of the fixed part 500 closer together, resulting in a more stable structure that is less prone to tipping over.

[0141] The surface 911 of the first magnetic element faces the second magnetic element 920. The surface 912 of the second magnetic element faces the second magnetic element 920. The surfaces 911 and 912 of the first magnetic element are neither perpendicular nor parallel to each other. The inclined plane of angle 212 is not parallel to the surface 911 of the first magnetic element.

[0142] When viewed along the surface 911 parallel to the first magnetic element, the oblique angle 212 is at least partially located between the first magnetic element 910 and the second magnetic element 920.

[0143] In summary, this example optical element driving mechanism has multiple moving parts, multiple driving assemblies, a positioning assembly, and a stabilizing assembly. The positioning assembly increases the load capacity of the optical element driving mechanism, reduces the number of required parts, and increases assembly flexibility. The stabilizing assembly increases the internal structural stability of the optical element driving mechanism. Multiple driving assemblies drive multiple moving parts and optical elements, thereby adjusting the photographic imaging of the optical element driving mechanism to adapt to different photographic needs.
