[0079] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an overly literal or overly formal sense unless expressly so defined herein.

[0080] Reference is first made to Figure 1 , Figure 1 is a schematic view of an electronic device 1 according to some embodiments of the present disclosure. As shown in Figure 1 , an optical element driving mechanism 100 according to some embodiments of the present disclosure can be installed in an electronic device 1, such as a smartphone or a digital camera, for example, but the present disclosure is not limited thereto. It should be noted that Figure 1 the position and size relationship between the optical element driving mechanism 100 and the electronic device 1 shown in is merely an example and is not intended to limit the position and size relationship between the optical element driving mechanism 100 and the electronic device 1. In fact, the optical element driving mechanism 100 can be installed at different positions in the electronic device 1 according to different requirements.

[0081] Figure 2 Reference is made to Figure 2 , which is a perspective view of an optical element driving mechanism 100, an optical element 110, and a light sensing module 120 according to some embodiments of the present disclosure. The optical element driving mechanism 100 carries an optical element 110. The optical element driving mechanism 100 can be provided with a light sensing module 120 inside or outside. The light sensing module 120 is located downstream of the light incident position of the optical element driving mechanism 100. An incident light L enters the optical element 110 in the optical element driving mechanism 100 along an optical axis O and then reaches the light sensing module 120 (which can be a camera, for example) for imaging.

[0082] Figure 3 is an exploded view of an optical element driving mechanism 100 according to some embodiments of the present disclosure. Please refer to Figure 2 and Figure 3 , the optical element driving mechanism 100 can include a fixed part 10, a movable part 20, a driving assembly 30, and a spring leaf 40. The driving assembly 30 can drive the movable part 20 to move relative to the fixed part 10.

[0083] The fixed part 10 can include a bottom plate 11, a base 12, a first wall 13a, a second wall 13b, a first side wall 13c, a second side wall 13d, a top cover 14, a first fixed wire clamp 15a, a second fixed wire clamp 15b, a plurality of first wire winding shafts 16a, a plurality of second wire winding shafts 16b, a wire winding shaft partition 17, and a plurality of partition walls 18.

[0084] In some embodiments, the bottom plate 11 can have a flat plate shape, and be perpendicular to the optical axis O. In some embodiments, the bottom plate 11 can extend along a first direction D1. The base 12 can be disposed on the bottom plate 11. In some embodiments, the base 12 can be fixedly disposed on the bottom plate 11.

[0085] The first wall 13a extends from the base 12 along a second direction D2, and the second wall 13b also extends from the base 12 along the second direction D2. It should be noted that the second direction D2 can be parallel to the optical axis O, and the second direction D2 can be perpendicular to the first direction D1. The first wall 13a and the second wall 13b are opposite to each other in the first direction D1. The first wall 13a can include a first wall protrusion 13a’.

[0086] The first side wall 13c extends from the base 12 along the second direction D2, and the second side wall 13d also extends from the base 12 along the second direction D2. The first side wall 13c and the second side wall 13d are opposite to each other in a third direction D3. It should be noted that the third direction D3 can be perpendicular to the first direction D1 and the second direction D2. The first side wall 13c includes a plurality of first winding shaft openings 13c’, and the second side wall 13d includes a plurality of second winding shaft openings 13d’.

[0087] The top cover 14 is disposed on the first wall 13a, the second wall 13b, the first side wall 13c, and the second side wall 13d. The top cover 14 can include an optical element opening 141, an optical element protrusion opening 142, and a convex column opening 143. The first fixed wire clamp 15a is disposed on the first wall 13a, and the second fixed wire clamp 15b is disposed on the second wall 13b. The optical element opening 141 can overlap the optical element 110.

[0088] In some embodiments, the first winding shaft 16a and the second winding shaft 16b can be made of metal. The first winding shaft 16a and the second winding shaft 16b are located between the first side wall 13c and the second side wall 13d. The two ends of the first winding shaft 16a and the second winding shaft 16b are inserted into the first winding shaft opening 13c’ and the second winding shaft opening 13d’.

[0089] In other words, each first winding shaft 16a is located in the first winding shaft opening 13c’ and the second winding shaft opening 13d’, and each second winding shaft 16b is located in the first winding shaft opening 13c’ and the second winding shaft opening 13d’. In this way, the undesired movement and deformation of the first winding shaft 16a and the second winding shaft 16b can be avoided.

[0090] Please refer to Figure 4 , Figure 4The optical element drive mechanism 100 according to some embodiments of this disclosure is along... Figure 2 A cross-sectional view along line A-A'. In some embodiments, the first winding shaft 16a may be located above the second winding shaft 16b. Moreover, each first winding shaft 16a may correspond to a corresponding second winding shaft 16b. In some embodiments, each first winding shaft 16a and its corresponding second winding shaft 16b are arranged along the second direction D2. In some embodiments, the second winding shaft 16b may directly contact the base 12.

[0091] A bobbin partition 17 is disposed between the first sidewall 13c and the second sidewall 13d. The bobbin partition 17 includes a plurality of third bobbin openings 17'. The first bobbin 16a and the second bobbin 16b can pass through the third bobbin openings 17'. In this way, undesirable movement of the first bobbin 16a and the second bobbin 16b can be avoided.

[0092] The partition wall 18 can extend from the base 12 along the second direction D2. A portion of the partition wall 18 can be disposed against the first side wall 13c, and another portion of the partition wall 18 can be disposed against the second side wall 13d. That is, each partition wall 18 is in at least (direct) contact with either the first side wall 13c or the second side wall 13d. The partition wall 18 is disposed between the first side wall 13c and the second side wall 13d.

[0093] In some embodiments, a spacer 18 may be disposed between the first winding spools 16a to separate each first winding spool 16a from each other, and the spacer 18 may prevent undesirable movement of the first winding spools 16a and prevent deformation of the first winding spools 16a (not shown).

[0094] like Figure 4 As shown, in some embodiments, spacer 18 may be disposed between the second winding spools 16b to separate each second winding spool 16b from each other, and spacer 18 may prevent undesirable movement of the second winding spools 16b and prevent deformation of the second winding spools 16b.

[0095] It should be noted that in some embodiments, when viewed along the third direction D3, the height S1 of each spacer wall 18 is less than the height S2 of each second winding shaft 16b. In this way, undesirable movement of the second winding shaft 16b can be effectively avoided while minimizing the optical element drive mechanism 100.

[0096] It should be noted that in some embodiments, the bobbin partition 17 is disposed between the partition wall 18 abutting against the first sidewall 13c and the partition wall 18 abutting against the second sidewall 13d. In this way, the third bobbin opening 17' of the bobbin partition 17 can effectively support the middle portion of the first bobbin 16a and the second bobbin 16b to prevent deformation of the first bobbin 16a and the second bobbin 16b.

[0097] Please also refer to Figure 2 and Figure 3 The movable part 20 may include a support 21, a movable wire holder 22, and a protrusion 23.

[0098] The support 21 can support an optical element 110. The optical element 110 here can be an SOMA (e.g., a shutter, aperture), a prism, a lens, a camera module, a photosensitive element, or other optical-related components. The support 21 can include a support body 211 and an optical element protrusion 212.

[0099] In some embodiments, the carrier body 211 is generally I-shaped. That is, when viewed along the second direction D2, the width of the middle portion of the carrier body 211 is smaller than the width of the two ends of the carrier body 211, resulting in the carrier body 211 having an elongated middle portion. An optical element protrusion 212 is formed on the carrier body 211. In some embodiments, the optical element protrusion 212 may be formed on a first end 211a of the carrier body 211.

[0100] Furthermore, in some embodiments, the optical element protrusion 212 may extend through an opening 110a of the optical element 110. Alternatively, in other embodiments, the optical element protrusion 212 may be connected to the optical element 110 in other ways. In this way, when the carrier 21 moves, the optical element 110 also moves with the carrier 21.

[0101] The optical element protrusion 212 can also penetrate the optical element protrusion opening 142 of the top cover 14. The sides of the optical element protrusion opening 142 can limit the range of movement of the optical element protrusion 212.

[0102] For example, in some embodiments, the side of the optical element protrusion opening 142 may limit the range of movement of the optical element protrusion 212 along a first direction D1 to avoid undesirable movement of the carrier 21. For example, in some embodiments, the side of the optical element protrusion opening 142 may limit the range of movement of the optical element protrusion 212 along a third direction D3 to avoid undesirable movement of the carrier 21.

[0103] The movable wire holder 22 is disposed on the carrier seat 21. In some embodiments, the movable wire holder 22 is fixedly disposed on the elongated middle portion of the carrier seat body 211. When the movable wire holder 22 moves, the carrier seat 21 also moves along with the movable wire holder 22.

[0104] The protrusion 23 is disposed on the carrier seat 21. In some embodiments, the protrusion 23 can be disposed on a second end 211b of the carrier seat body 211. In some embodiments, the protrusion 23 can be made of metal. In some embodiments, the protrusion 23 can be electrically connected to the movable wire holder 22 by a metal wire (not shown) embedded by insert molding. The protrusion 23 can pass through the protrusion opening 143 of the top cover 14. The side of the protrusion opening 143 can limit the movement range of the protrusion 23.

[0105] For example, in some embodiments, the side of the protrusion opening 143 can limit the movement range of the protrusion 23 along the first direction D1 to avoid undesired movement of the carrier seat 21. For example, in some embodiments, the side of the protrusion opening 143 can limit the movement range of the protrusion 23 along the third direction D3 to avoid undesired movement of the carrier seat 21.

[0106] In some embodiments, the height 23’ of the protrusion 23 can be greater than the height of the optical element protrusion 212 when viewed along the third direction D3. In some embodiments, the movable wire holder 22 can be located between the optical element protrusion 212 and the protrusion 23 when viewed along the third direction D3. In this way, the structure of the carrier seat 21 can be more stable, and miniaturization can be facilitated.

[0107] The driving assembly 30 can include a first wire 31 and a second wire 32. In some embodiments, the first wire 31 includes shape memory alloys (SMA). In some embodiments, the second wire 32 includes shape memory alloys.

[0108] The first wire 31 is connected to the first fixed wire holder 15a and the movable wire holder 22, such that when the first wire 31 receives a current, the first wire 31 can contract (or expand) to drive the movable wire holder 22. In turn, the carrier seat 21 can move relative to the fixed portion 10 along the first direction D1.

[0109] The second wire 32 is connected to the second fixed wire holder 15b and the movable wire holder 22 (which can be referred to as the second fixed wire holder 15b and the movable wire holder 22 in the following description). Figure 4), such that when the second wire 32 receives current, the second wire 32 can contract (or extend) to drive the movable wire holder 22. In turn, the carrier 21 can move relative to the fixed portion 10 along the first direction D1. It should be noted that the direction driven by the second wire 32 can be opposite to the direction driven by the first wire 31.

[0110] In some embodiments, when the first wire 31 receives current and drives the carrier 21, the optical element 110 at least partially overlaps (or, completely overlaps) the optical element opening 141 as viewed along the second direction D2. In this way, the incident light L reaching the photosensitive module for imaging can be allowed.

[0111] In some embodiments, when the second wire 32 receives current and drives the carrier 21, the optical element 110 at least partially does not overlap (or, completely does not overlap) the optical element opening 141 as viewed along the second direction D2. In this way, the incident light L reaching the photosensitive module for imaging can be increased.

[0112] The first wire 31 and the second wire 32 are separated by the bobbin partition 17. That is, the bobbin partition 17 can be disposed between the first wire 31 and the second wire 32. In this way, undesired movement of the first wire 31 and the second wire 32 can be avoided, and the first wire 31 and the second wire 32 can be prevented from entangling with each other.

[0113] The first wire 31 at least partially surrounds the first bobbin 16a and the second bobbin 16b. Also, the second wire 32 at least partially surrounds the first bobbin 16a and the second bobbin 16b (see Figure 4 ). In this way, the length of the first wire 31 and the second wire 32 can be increased, and the contraction and extension paths of the first wire 31 and the second wire 32 can be limited, such that the contraction and extension of the first wire 31 and the second wire 32 are increased, and undesired movement of the first wire 31 and the second wire 32 can be avoided.

[0114] The spring 40 can include a first contact portion 41, a second contact portion 42, and a spring opening 40a. The spring 40 can be flexible. In some embodiments, the spring 40 always contacts the protrusion 23. In some embodiments, the spring 40 is always electrically connected to the protrusion 23 (see Figure 2 ). Please refer to Figure 2 and Figure 3 , the first contact portion 41 and the second contact portion 42 of the spring 40 can have similar shapes to each other.

[0115] Please refer to Figure 5 , Figure 5is a schematic view of an optical element driving mechanism 100 according to other embodiments of the present disclosure. As shown in Figure 5 In some embodiments, the first contact portion 41 and the second contact portion 42 of the spring piece 40 can have a trapezoidal shape, such that the spring piece 40 always contacts the convex column 23, and the spring piece 40 is always electrically connected to the convex column 23.

[0116] In some embodiments, the first contact portion 41 of the spring piece 40 can have a first protruding portion 41a, and the second contact portion 42 can have a second protruding portion 42a. As such, the spring piece 40 can always contact the convex column 23, and the spring piece 40 is always electrically connected to the convex column 23.

[0117] It should be noted that, regardless of the shape of the first contact portion 41 and the second contact portion 42 of the spring piece 40, a shortest distance S3 between the first contact portion 41 and the second contact portion 42 of the spring piece 40 is less than a size S4 of the convex column 23 (see Figure 2 ). In this way, the spring piece 40 can more effectively contact and electrically connect to the convex column 23. For example, in some embodiments, the shortest distance S3 between the first contact portion 41 and the second contact portion 42 of the spring piece 40 can be the shortest distance between the first protruding portion 41a and the second protruding portion 42a.

[0118] Please continue to refer to Figure 2 , the first wall protrusion 13a' of the first wall 13a can pass through the spring piece opening 40a of the spring piece 40 to fix the spring piece 40 to the first wall 13a. Moreover, a height S5 of the convex column 23 is greater than a height S6 of the first wall protrusion when viewed along the first direction D1. In this way, the spring piece 40 can more effectively contact and electrically connect to the convex column 23.

[0119] In summary, the optical element driving mechanism disclosed by the embodiments of the present disclosure can more quickly drive the optical element by applying a current to the first wire and the second wire, and accurately move the optical element to a desired position. Moreover, the optical element driving mechanism disclosed by the embodiments of the present disclosure has the effects of miniaturization and light weight. Furthermore, the optical element driving mechanism disclosed by the embodiments of the present disclosure also has the benefits of stability and durability.
