[0125] This specification provides numerous different embodiments or examples, and may use relative spatial terms to describe specific examples of the components and their arrangements to implement different features of this disclosure. For example, if this specification describes a first feature formed "on" and / or "above" a second feature, it indicates that it may include embodiments in which the first and second features are in direct contact, or embodiments in which an additional feature is formed between the first and second features, so that the first and second features are not in direct contact. Relative spatial terms are used to facilitate the description of the relationship between elements or features in the drawings and other elements or features. In addition to the orientations shown in the drawings, these spatial terms are intended to encompass different orientations of the device in use or operation. The device may be turned to different orientations (rotated 90 degrees or other orientations), and the relative spatial terms used herein may be interpreted accordingly. Furthermore, the same or similar symbols or letters may be used in different examples of this disclosure.

[0126] In this specification, the terms "comprising" and / or "having" are open-ended terms and should therefore be interpreted as "containing but not limited to...". Thus, when the terms "comprising" and / or "having" are used in the description of this disclosure, they specify the presence of the corresponding feature, area, step, operation, and / or element, but do not exclude the presence of one or more of the corresponding feature, area, step, operation, and / or element.

[0127] Please refer to this first. Figure 1 as well as Figure 2 . Figure 1This is a schematic diagram of electronic device 1, optical element 10, and optical system 20. Figure 2 This is a schematic diagram of optical element 10 and optical system 20. Electronic device 1 can be a tablet computer, smartphone, etc. Optical element 10 can be a lens, for example, a telescope. Optical element 10 can be made of plastic or glass. Optical element 10 can be circular or other shapes. Optical element 10 and optical system 20 can be mounted on electronic device 1 for the user to capture images. Optical system 20 can carry optical element 10 and drive the optical element 10 to adjust its position for capturing clear images. Optical element 10 and optical system 20 can be positioned on the top area of ​​electronic device 1 to increase the display area of ​​electronic device 1.

[0128] Optical element 10 has an optical axis O. Optical axis O is a virtual axis passing through the center of optical element 10. When optical element 10 is aligned with optical system 20, the optical axis O of optical element 10 is substantially coincident with the central axis of optical system 20. Therefore, the optical axis O of optical element 10 may be used to illustrate relevant features of optical system 20 in the accompanying drawings and description. It should be understood that since optical element 10 is movably mounted within optical system 20, the optical axis O of optical element 10 may not be perfectly coincident with the central axis of optical system 20 due to movement, shaking, rotation, tilting, etc., of optical system 20. Optical system 20 may be connected to an external module, such as a photosensitive element module (e.g., a module including a charge-coupled detector (CCD)), so that light entering optical system 20 is imaged on the external module.

[0129] Next, please refer to Figure 3 . Figure 3 This is an exploded view of the optical system 20. The optical system 20 includes an outer frame 21, a base 22, a drive module 23, and an optical mechanism 100. The outer frame 21 and the base 22 are arranged along the optical axis O, and the outer frame 21 and the base 22 form a receiving space to accommodate the optical mechanism 100. The outer frame 21 has a top wall 21T and four side walls 21S. The top wall 21T is perpendicular to the optical axis O. The side walls 21S extend from the edge of the top wall 21T in a direction parallel to the optical axis O. Compared to the base 22, the top wall 21T of the outer frame 21 is closer to an incident light. The top wall 21T and the base 22 are used to limit the range of motion of the optical mechanism 100.

[0130] The drive module 23 is located between the outer frame 21 and the base 22, and can be used to drive the optical mechanism 100 to move relative to the outer frame 21 in a direction perpendicular to the optical axis O. The drive module 23 includes a body 23B and four drive elements 23D. The body 23B can be further divided into a first body part 23B1 and a second body part 23B2. Specifically, the optical mechanism 100 is located on the first body part 23B1, the first body part 23B1 is located on the second body part 23B2, and the second body part 23B2 is located on the base 22. The drive elements 23D are disposed on the first body part 23B1 and the second body part 23B2, and are connected to the first body part 23B1 and the second body part 23B2. In this embodiment, when viewed along the optical axis O, the four drive elements 23D do not cross or overlap each other, and are symmetrically arranged in pairs. However, deviations may occur during assembly, causing the drive elements 23D to be not symmetrically arranged. The drive element 23D may be made of shape memory alloy (SMA), including iron-based alloys, copper-based alloys (e.g., copper-zinc-aluminum alloys, copper-aluminum-nickel alloys), titanium-nickel alloys, titanium-palladium alloys, titanium-nickel-copper alloys, titanium-nickel-palladium alloys, gold-cadmium alloys, indium-thallium alloys, or combinations of the above shape memory alloys.

[0131] Because shape memory alloys deform with temperature changes, the temperature and length of each of the four drive elements 23D can be controlled by applying the same or different drive signals (e.g., current, voltage) to a single power source, thus producing the same or different length changes. For example, when a drive signal is applied to change the temperature of the drive element 23D, its length lengthens or shortens, causing the first body portion 23B1 and the optical mechanism 100 on it to move. This changes the positional relationship of the optical mechanism 100 relative to the outer frame 21. When the drive signal is stopped, the drive element 23D returns to its original length.

[0132] Next, besides Figure 3 In addition, please refer to the following: Figures 4 to 9 To understand the optical mechanism 100. Figure 4 This is a top view of the optical mechanism 100. Figure 5 This is a bottom view of the optical mechanism 100. Figures 6 to 9This is a perspective view of optical mechanism 100, where the viewing angle and omitted elements are not entirely identical. When viewed along optical axis O, optical mechanism 100 has a polygonal structure, for example, a quadrilateral. For ease of explanation, the four sides of optical mechanism 100 are defined as a first side 1001, a second side 1002, a third side 1003, and a fourth side 1004. First side 1001 is relative to third side 1003, and second side 1002 is relative to fourth side 1004. First side 1001 and third side 1003 are approximately parallel, while second side 1002 and fourth side 1004 are approximately parallel. First side 1001, second side 1002, third side 1003, and fourth side 1004 are approximately perpendicular to a first axis A1. When viewed along the first axis A1, second side 1002 and fourth side 1004 are parallel to and extend along a second axis A2. When viewed along the first axis A1, the first side 1001 and the third side 1003 are parallel to and extend along a third axis A3.

[0133] The optical mechanism 100 includes a fixed part I, a movable part M, a driving assembly D, a guiding assembly G, a first circuit assembly C1, and a second circuit assembly C2 (see below). Figure 11 as well as Figure 22 The system comprises a sensing component S and a control component C. A movable part M is connected to the optical element 10 and is movable relative to the fixed part I. A driving component D drives the movable part M to move relative to the fixed part I along a first axis A1, which is substantially parallel to the optical axis O. A guiding component G guides the movement of the movable part M relative to the fixed part I. A first circuit component C1 and a second circuit component C2 are used to input and transmit current. The sensing component S is used to sense the movement of the movable part M relative to the fixed part I. The control component C controls the driving component D. The description in this specification is merely illustrative; components may be added or removed according to actual needs. Furthermore, for clarity, some components may be omitted in the accompanying drawings.

[0134] In this embodiment, the fixing part I includes a frame 110 and a base 120. The movable part M includes a support 130. The driving assembly D includes a first driving element 140, a second driving element 150, two first driving element fixing elements 160, two second driving element fixing elements 170, a first contact element 180, and a second contact element 190. The guiding assembly G includes a magnetically conductive element 200, a first magnetic element 210, a second magnetic element 220, a first guiding element 230, and a second guiding element 240. The first circuit assembly C1 includes a plurality of first circuits 250. The second circuit assembly C2 includes a plurality of second circuits 260 (see...). Figure 11 as well as Figure 22The sensing component S includes a reference element 270 and a sensing element 280 corresponding to the reference element 270. The control component C includes a first control unit 290 and a second control unit 300, wherein the sensing element 280 and the first control unit 290 can be packaged in a first package structure 310, and the second control unit 300 can be packaged in a second package structure 320. In some embodiments, the optical mechanism 100 further includes a reinforcing element 330 (see...). Figure 10 ) and an external connection terminal 340 (see Figure 11 as well as Figure 22 ).

[0135] Next, besides Figures 3 to 9 In addition, please refer to the following: Figure 10 as well as Figure 11 To understand the fixed part I. Figure 10 This is a schematic diagram of the frame 110 and the reinforcing element 330. Figure 11 This is a schematic diagram of the base 120 and the second circuit assembly C2. A frame 110 is disposed above the base 120. The frame 110 is fixedly connected to the base 120. The frame 110 has a receiving space for accommodating the movable part M. Specifically, the movable part M, the drive assembly D, the guide assembly G, the first circuit assembly C1, and the second circuit assembly C2 can be disposed between the frame 110 and the base 120.

[0136] In some embodiments, the frame 110 is made of plastic material, while the reinforcing element 330 is made of metal material. The reinforcing element 330 is formed in the frame 110 by insert molding. The reinforcing element 330 is at least partially embedded and not exposed in the frame 110. The reinforcing element 330 is used to enhance the mechanical strength of the frame 110. Furthermore, the reinforcing element 330 may have one or more openings 331. During the formation of the frame 110 and the reinforcing element 330, the plastic material, as part of the frame 110, can fill the openings 331 of the reinforcing element 330 in a molten state at high temperature to increase the contact area between the frame 110 and the reinforcing element 330, thereby strengthening the connection between the frame 110 and the reinforcing element 330. It is worth noting that there is a gap between the reinforcing element 330 and the magnetically conductive element 200, thus preventing a short circuit.

[0137] In some embodiments, the base 120 is made of plastic material, while the second circuit 260 of the second circuit assembly C2 is made of metal material. The second circuit 260 of the second circuit assembly C2 is formed in the base 120 by in-mold forming. The second circuit 260 is at least partially embedded and not exposed in the base 120.

[0138] Next, besides Figures 3 to 9 In addition, please refer to the following: Figure 12To understand the activities department M. Figure 12 This is a perspective view of the support 130. When viewed from the direction of incident light, the movable part M is fully exposed from the fixed part I. In other words, when viewed from the direction of incident light, the support 130 is not obstructed by the frame 110 and the base 120. The support 130 does not directly contact the frame 110 and the base 120. The support 130 is hollow to support the optical element 10. In some embodiments, the support 130 is made of plastic material.

[0139] The support 130 may include a first magnetic element receiving portion 131, a second magnetic element receiving portion 132, and a reference element receiving portion 133. The first magnetic element receiving portion 131, the second magnetic element receiving portion 132, and the reference element receiving portion 133 are located on the top surface of the support 130. The first magnetic element receiving portion 131 and the second magnetic element receiving portion 132 are located on a first side 1001, while the reference element receiving portion 133 is located on a second side 1002. The first magnetic element receiving portion 131, the second magnetic element receiving portion 132, and the reference element receiving portion 133 are respectively used to receive a first magnetic element 210, a second magnetic element 220, and a reference element 270. In some embodiments, the first magnetic element receiving portion 131, the second magnetic element receiving portion 132, and the reference element receiving portion 133 are recesses.

[0140] To prevent damage to other components when the support 130 moves to a certain limit, the support 130 may further include one or more stop structures. In this embodiment, the support 130 includes a plurality of upper stop portions 134. The upper stop portions 134 protrude from the top surface of the support 130. Specifically, the upper stop portions 134 are closer to the top wall 21T of the outer frame 21 than the top surface of the support 130. The upper stop portions 134 can limit the range of motion of the support 130. For example, when the support 130 moves toward the top wall 21T of the outer frame 21 to its limit, the upper stop portions 134 of the support 130 may come into contact with the top wall 21T of the outer frame 21.

[0141] Next, besides Figures 3 to 9 In addition, please refer to the following: Figure 13 as well as Figure 14 In order to understand the driver component D and the boot component G. Figure 13 as well as Figure 14 This is a schematic diagram of the drive component D and the guide component G from different perspectives. When viewed along the first axis A1, the drive component D and the guide component G are located on the first side 1001.

[0142] The first driving element 140 and the second driving element 150 have elongated structures but different configurations. For example, the first driving element 140 and the second driving element 150 have different shapes. In this embodiment, the first driving element 140 is V-shaped, while the second driving element 150 is inverted V-shaped. The first driving element 140 and the second driving element 150 may be made of shape memory alloy and include materials similar to or the same as those of the driving element 23D. The first driving element fixing element 160 includes a first clamping portion 161 for fixing a first end of the first driving element 140 and a second clamping portion 162 for fixing a second end of the first driving element 140. The second driving element fixing element 170 may also include clamping structures for fixing both ends of the second driving element 150. This configuration can improve heat dissipation efficiency. In addition, one or more holes 163, 173 may be provided around the first driving element fixing element 160 and the second driving element fixing element 170 to further help dissipate heat from the first driving element 140 and the second driving element 150. It is worth noting that the holes 163 and 173 may be slightly away from the first drive element 140 and the second drive element 150 to avoid excessive loss of the energy required for the first drive element 140 and the second drive element 150 to drive.

[0143] The two ends of the first driving element 140 and the second driving element 150 are fixed, and their central portions directly contact the first contact element 180 and the second contact element 190 respectively disposed on the support base 130. When a driving signal (e.g., current, voltage) is applied to the first driving element 140 and the second driving element 150, the length changes of the first driving element 140 and the second driving element 150 can be controlled. For example, when the length of the first driving element 140 is shortened, the support base 130 can be driven to move along the first axis A1 toward the top wall 21T (upward) of the outer frame 21 through the first contact element 180, which directly contacts the first driving element 140 and the support base 130. Similarly, when the length of the second driving element 150 is shortened, the support base 130 can be driven to move along the first axis A1 toward the base 22 (downward) through the second contact element 190, which directly contacts the second driving element 150 and the support base 130.

[0144] The guide assembly G guides the movement of the movable part M relative to the fixed part I along the first axis A1. The magnetically conductive element 200 is fixedly disposed on the frame 110. The frame 110 may include a fixing element 115 (see...). Figure 10The magnetic element 200 is fixed to the frame 110 by an opening 201 corresponding to the fixing element 115 of the frame 110. The opening 201 may have an irregular shape, such as a polygon with non-straight sides, to further increase the contact area between the magnetic element 200 and the frame 110, thereby strengthening the connection between them. Furthermore, the magnetic element 200 may have a snap-fit ​​portion 202 for further fixing to the fixing element 115 of the frame 110. The magnetic element 200 is at least partially embedded and not exposed in the frame 110. In some embodiments, the snap-fit ​​portion 202 is exposed in the frame 110 (e.g., ...). Figure 7 (As shown).

[0145] The magnetically conductive element 200 includes a magnetically conductive element surface 205 facing the first driving element 140 and the first magnetic element 210. Specifically, the first driving element 140 is located between the magnetically conductive element surface 205 of the magnetically conductive element 200 and a first magnetic element surface 215 of the first magnetic element 210. The magnetically conductive element surface 205 is exposed outside the frame 110. The magnetically conductive element 200 has a magnetically conductive material and is therefore attracted by the first magnetic element 210 and the second magnetic element 220. The magnetically conductive material represents a material having magnetic permeability. For example, ferromagnetic materials include iron (Fe), nickel (Ni), cobalt (Co), or alloys thereof.

[0146] The first magnetic element 210 and the second magnetic element 220 may be magnets. The first magnetic element 210 includes a first magnetic pole pair. The first magnetic pole pair includes an N pole and an S pole (only when arranged along the second axis A2) Figure 13 as well as Figure 14 (As shown). The first magnetic element 210 includes a first magnetic element surface 215 facing the magnetically conductive element 200, and the first magnetic element surface 215 is perpendicular to the second axis A2. The second magnetic element 220 includes a second magnetic pole pair. The second magnetic pole pair includes an N pole and an S pole arranged along the second axis A2 (only when...). Figure 13 as well as Figure 14 (As shown). The second magnetic element 220 includes a second magnetic element surface 225 facing the magnetically conductive element 200, and the second magnetic element surface 225 is perpendicular to the second axis A2. Notably, the N and S poles of the first magnetic pole pair of the first magnetic element 210 are aligned in the opposite direction to the N and S poles of the second magnetic pole pair of the second magnetic element 220. This pole configuration strengthens the generated magnetic field lines, enhancing the attractive force between the first magnetic element 210 and the second magnetic element 220 and the magnetically conductive element 200 in a magnetic field circulation manner.

[0147] The first guide element 230 and the second guide element 240 are located on the first side 1001. The first guide element 230 and the second guide element 240 may have substantially the same structure. When viewed along the first axis A1, the area of ​​the first guide element 230 is substantially the same as the area of ​​the second guide element 240. The first guide element 230 and the second guide element 240 may have an elongated structure, for example, a rod or bar shape. The first guide element 230 and the second guide element 240 may extend along the first axis A1 and pass through at least a portion of the frame 110, the base 120, and the support 130.

[0148] Next, please refer to Figures 15 to 20 To further understand how the first guide element 230 and the second guide element 240 are housed in the optical mechanism 100. Figures 15 to 18 This is a partial enlarged view of the optical mechanism 100, where the viewpoint and omitted elements are not entirely the same. Figure 19 as well as Figure 20 The optical mechanism 100 is along Figure 6 The diagram shows cross-sectional views of lines AA and BB. The guide assembly G includes a first receiving portion 410, a second receiving portion 420, a third receiving portion 430, a fourth receiving portion 440, a fifth receiving portion 450, and a sixth receiving portion 460. For ease of explanation, the first receiving portions 410 to the sixth receiving portions 460 are considered as part of the guide assembly G, but it should be understood that the first receiving portions 410 to the sixth receiving portions 460 are formed on the frame 110, the base 120, or the support 130. Specifically, the first receiving portion 410 and the fourth receiving portion 440 are fixedly disposed on the movable portion M (support 130). The second receiving portion 420 and the fifth receiving portion 450 are fixedly disposed on the base 120. The third receiving portion 430 and the sixth receiving portion 460 are fixedly disposed on the frame 110.

[0149] The first receiving portion 410, the second receiving portion 420, and the third receiving portion 430 are used to receive the first guide element 230, and each has a recessed structure corresponding to the first guide element 230. The first receiving portion 410 and the second receiving portion 420 are arranged along the second axis A2. The first receiving portion 410 and the third receiving portion 430 are arranged along the second axis A2. The second receiving portion 420 and the third receiving portion 430 are arranged along the first axis A1.

[0150] In some embodiments, the optical mechanism 100 further includes a first adhesive element 510 (only when the optical mechanism 100 includes a first adhesive element 510). Figure 15(Shown schematically). The first guide element 230 is fixedly connected to the second receiving portion 420 via a first adhesive element 510, and the first adhesive element 510 directly contacts the frame 110 and the base 120. In some embodiments, a shortest distance between the second receiving portion 420 and the first guide element 230 is less than a shortest distance between the third receiving portion 430 and the first guide element 230. That is, the second receiving portion 420 on the base 120 is closer to the first guide element 230 than the third receiving portion 430 on the frame 110. In this way, the first adhesive element 510 can flow from the third receiving portion 430 on the frame 110 to the second receiving portion 420 on the base 120. Moreover, when the first adhesive element 510 is applied to fix the first guide element 230, collisions between the frame 110 and the first guide element 230 can be avoided, thereby reducing the possibility of assembly misalignment and improving assembly accuracy.

[0151] The second receiving portion 420 and the third receiving portion 430 each have a second receiving portion groove 421 and a third receiving portion groove 431 for receiving the first adhesive element 510. When viewed along the first axis A1, the third receiving portion groove 431 at least partially overlaps with the base 120. Furthermore, the second receiving portion 420 has a second receiving portion anti-overflow structure 422 for receiving a portion of the first adhesive element 510. When viewed along the first axis A1, the second receiving portion anti-overflow structure 422 is adjacent to the second receiving portion groove 421. The third receiving portion 430 has a third receiving portion anti-overflow structure 432 for receiving a portion of the first adhesive element 510. When viewed along the first axis A1, the third receiving portion anti-overflow structure 432 is adjacent to the third receiving portion groove 431. When viewed along the first axis A1, the second receiving portion anti-overflow structure 422 and the third receiving portion anti-overflow structure 432 at least partially overlap. In other words, when the first adhesive element 510 is applied to fix the first guide element 230, the second receiving groove 421 and the third receiving groove 431 can increase the contact area between the first adhesive element 510 and the base 120 and the frame 110. Moreover, the second receiving anti-overflow structure 422 and the third receiving anti-overflow structure 432 can accommodate a portion of the first adhesive element 510 to reduce the possibility of the first adhesive element 510 overflowing into other elements.

[0152] Similarly, the fourth receiving portion 440, the fifth receiving portion 450, and the sixth receiving portion 460 are used to receive the second guide element 240, and each has a recessed structure corresponding to the second guide element 240. The fourth receiving portion 440 and the fifth receiving portion 450 are arranged along the second axis A2. The fourth receiving portion 440 and the sixth receiving portion 460 are arranged along the second axis A2. The fifth receiving portion 450 and the sixth receiving portion 460 are arranged along the first axis A1.

[0153] In some embodiments, the optical mechanism 100 further includes a second adhesive element 520 (shown schematically only in Figure 17). The second guide element 240 is fixedly connected to the fifth receiving portion 450 via the second adhesive element 520, and the second adhesive element 520 directly contacts the frame 110 and the base 120. In some embodiments, a shortest distance between the fifth receiving portion 450 and the second guide element 240 is less than a shortest distance between the sixth receiving portion 460 and the second guide element 240. That is, the fifth receiving portion 450 on the base 120 is closer to the second guide element 240 than the sixth receiving portion 460 on the frame 110. This facilitates the flow of the second adhesive element 520 from the sixth receiving portion 460 on the frame 110 to the fifth receiving portion 450 on the base 120. Moreover, when the second adhesive element 520 is applied to fix the second guide element 240, collisions between the frame 110 and the second guide element 240 are avoided, reducing the possibility of assembly misalignment and improving assembly accuracy.

[0154] The fifth receiving portion 450 and the sixth receiving portion 460 each have a fifth receiving portion groove 451 and a sixth receiving portion groove 461 for receiving the second adhesive element 520, respectively. When viewed along the first axis A1, the fifth receiving portion groove 451 at least partially overlaps with the base 120. Furthermore, the fifth receiving portion 450 has a fifth receiving portion anti-overflow structure 452 for receiving a portion of the second adhesive element 520. When viewed along the first axis A1, the fifth receiving portion anti-overflow structure 452 is adjacent to the second receiving portion groove 421. The sixth receiving portion 460 has a sixth receiving portion anti-overflow structure 462 for receiving a portion of the second adhesive element 520. When viewed along the first axis A1, the sixth receiving portion anti-overflow structure 462 is adjacent to the sixth receiving portion groove 461. When viewed along the first axis A1, the fifth receiving portion anti-overflow structure 452 and the sixth receiving portion anti-overflow structure 462 at least partially overlap. In other words, when the second adhesive element 520 is applied to fix the second guide element 240, the fifth receiving groove 451 and the sixth receiving groove 461 can increase the contact area between the second adhesive element 520 and the base 120 and the frame 110. Moreover, the fifth receiving anti-overflow structure 452 and the sixth receiving anti-overflow structure 462 can accommodate a portion of the second adhesive element 520 to reduce the possibility of the second adhesive element 520 overflowing into other elements.

[0155] It is worth noting that, when viewed along the first axis A1, the first receiving portion 410 and the fourth receiving portion 440 have different structures. For example, when viewed along the first axis A1, the first receiving portion 410 is V-shaped, while the fourth receiving portion 440 is U-shaped. In other words, the fourth receiving portion 440 includes a guide surface 445 facing the second guide element 240 (only when viewed along the first axis A1). Figure 12(As shown). The guide surface 445 is planar. The guide surface 445 contacts the second guide element 240. The guide surface 445 is perpendicular to the second axis A2. Typically, the V-shaped first receiving portion 410 and the first guide element 230 can be more closely fitted than the U-shaped fourth receiving portion 440 and the second guide element 240.

[0156] Furthermore, on the second axis A2, the shortest distance between the first magnetic element 210 and the magnetically conductive element 220 is less than the shortest distance between the first guiding element 230 and the magnetically conductive element 200. That is, the first magnetic element 210 is closer to the magnetically conductive element 200 than the first guiding element 230. Similarly, on the second axis A2, the second magnetic element 220 is closer to the magnetically conductive element 200 than the second guiding element 240. In this way, because the first magnetic element 210 and the second magnetic element 220 are closer to the magnetically conductive element 200, the attractive force between the first magnetic element 210 and the second magnetic element 220 and the magnetically conductive element 200 can be increased, and space can be effectively utilized to achieve miniaturization.

[0157] The attraction between the first magnetic element 210 and the second magnetic element 220 and the magnetic conductive element 200, as well as the first guide element 230 and the second guide element 240 in close contact with the carrier 130, ensures the range of motion of the carrier 130 in a certain dimension (e.g., the first axis A1) and prevents the carrier 130 from wobbling, rotating, tilting, etc.

[0158] Next, besides Figures 3 to 9 In addition, please refer to the following: Figure 21 as well as Figure 22 In order to understand the first circuit component C1, the second circuit component C2, the sensing component S, and the control component C. Figure 21 as well as Figure 22 This is a perspective view of the optical mechanism 100, where some omitted components are not entirely identical. When viewed along the first axis A1, the sensing component S is located on the second side 1002. When viewed along the first axis A1, the first circuit component C1 is located on the second side 1002. When viewed along the first axis A1, the external connection terminal 340 is located on the second side 1002.

[0159] The first circuit assembly C1 has a plate-like structure perpendicular to the first axis A1. The first circuits 250 of the first circuit assembly C1 are distributed on a first imaginary plane, which is parallel to the first axis A1. As previously described, the second circuit assembly C2 can be fixedly mounted on the base 120 by in-mold forming. The second circuits 260 of the second circuit assembly C2 are distributed on a second imaginary plane, which is not parallel to the first imaginary plane. Furthermore, in this embodiment, at least a portion of the external connection terminal 340 and the second circuit 260 have an integrated structure. Current can be passed to the optical mechanism 100 through the external connection terminal 340. Specifically, the external connection terminal 340 can be electrically connected to an external circuit (not shown) outside the optical mechanism 100, and the external connection terminal 340 may include several pins.

[0160] The reference element 270 may be a magnetic element. The sensing element 280 may be a Hall sensor, a giant magnetoresistive (GMR) sensor, a tunneling magnetoresistive (TMR) sensor, etc. The reference element 270 may be disposed on the movable part M. For example, the reference element 270 may be disposed on the support 130. The sensing element 280 may be disposed on and electrically connected to the first circuit assembly C1. The sensing element 280 can sense the reference element 270 to obtain the position of the movable part M. Specifically, the sensing element 280 can sense the change in the magnetic field lines of the reference element 270 (including but not limited to the magnetic field line density and magnetic field line direction) to obtain the position of the support 130. The position of the movable part M can be known in real time through the sensing assembly S.

[0161] As shown in the figure, the shortest distance between the sensing component S and the first guide element 230 is less than the shortest distance between the sensing component S and the second guide element 240. That is, the first guide element 230 is closer to the sensing component S than the second guide element 240. As mentioned above, because the first receiving portion 410 and the first guide element 230 may be closer together than the fourth receiving portion 440 and the second guide element 240, setting the sensing component S closer to the first guide element 230 can improve sensing accuracy.

[0162] The drive assembly D can be controlled by the first control unit 290 and the second control unit 300. The first drive element 140 and the second drive element 150 can be controlled independently. The first control unit 290, encapsulated in the first package structure 310, outputs a first drive signal to the first drive element 140. The second control unit 300, encapsulated in the second package structure 320, outputs a second drive signal to the second drive element 150. Based on the position of the moving part M sensed by the sensing component S, the first control unit 290 and the second control unit 300 can correspondingly control the drive signals transmitted to the first drive element 140 and the second drive element 150 to achieve closed-loop feedback. The first package structure 310 and the second package structure 320 are independent of each other, and there is a gap between the first package structure 310 and the second package structure 320. That is, the first package structure 310 does not contact the second package structure 320.

[0163] The first package structure 310 is electrically connected to an external circuit sequentially via a first circuit component C1 and a second circuit component C2. The second package structure 320 is also electrically connected to an external circuit sequentially via the first circuit component C1 and the second circuit component C2. The drive component D is electrically connected to the first package structure 310 and the second package structure 320 sequentially via the second circuit component C2 and the first circuit component C1. By independently controlling the first drive element 140 and the second drive element 150, greater design flexibility and high stability and accuracy can be achieved. However, in some other embodiments, it is also possible to jointly control the first drive element 140 and the second drive element 150 using a single control unit.

[0164] Next, please refer to Figure 4 , Figure 5 , Figure 23 , Figure 24 In order to understand some other features of the optical mechanism 100. Figure 23 This is a partial enlarged view of the optical mechanism 100. Figure 24 It is the optical mechanism 100 along Figure 6 A cross-sectional view of line CC.

[0165] Frame 110 includes a first frame surface 111, a second frame surface 112, and a third frame surface 113. Base 120 includes a first base surface 121, a second base surface 122, a third base surface 123, a fourth base surface 124, a fifth base surface 125, a first opening 126, a second opening 127, and a third opening 128. The first frame surface 111, the second frame surface 112, the first base surface 121, the second base surface 122, the third base surface 123, and the fourth base surface 124 are all perpendicular to the first axis A1.

[0166] The first frame surface 111, the second frame surface 112, and the third frame surface 113 face the base 120. The first base surface 121 and the third base surface 123 face the frame 110. The second base surface 122 faces in the opposite direction to the first base surface 121. For ease of explanation, a first direction D1 is defined, and the first direction D1 faces in the opposite direction to the second base surface 122. For example, in Figure 5 In the diagram, the first direction, D1, is the direction that penetrates the paper.

[0167] When viewed along the first axis A1, the shortest distance between the first frame surface 111 and the movable part M is less than the shortest distance between the second frame surface 112 and the movable part M. That is, the first frame surface 111 is closer to the support base 130 than the second frame surface 112. On the first axis A1, the third base surface 123 is located between the first base surface 121 and the fourth base surface 124. On the first axis A1, the shortest distance between the first base surface 121 and the third base surface 123 is greater than the shortest distance between the first base surface 121 and the fourth base surface 124. That is, on the first axis A1, the fourth base surface 124 is closer to the third base surface 123 than the first base surface 121.

[0168] The first frame surface 111 faces the third base surface 123, and the first frame surface 111 and the third base surface 123 are parallel. The second frame surface 112 faces the fourth base surface 124, and the second frame surface 112 and the fourth base surface 124 are parallel. A shortest distance between the first frame surface 111 and the third base surface 123 is less than a shortest distance between the second frame surface 112 and the fourth base surface 124. That is, the first frame surface 111 and the third base surface 123 are closer together than the second frame surface 112 and the fourth base surface 124. Furthermore, as... Figure 23 As shown, the thickness of the area where the fourth base surface 124 is located is thinner than the thickness of the area where the third base surface 123 is located, and the support effect achieved by the third base surface 123 may be more stable. In some embodiments, the first frame surface 111 and the third base surface 123 may include a mutually positioning structure.

[0169] In some embodiments, in a direction perpendicular to the first base surface 121, the second base surface 122 at least partially overlaps with the drive assembly D. For example... Figure 5As shown, when viewed from the first direction D1, the second opening 127 is located between the first opening 126 and the third opening 128. When viewed from the first direction D1, the drive assembly D is at least partially exposed in the first opening 126, the second opening 127, and the third opening 128. For example, when viewed from the first direction D1, the first drive element fixing element 160, the first clamping portion 161, and the second drive element fixing element 170 near the second side 1002 are at least partially exposed in the first opening 126. For example, when viewed from the first direction D1, the first drive element 140 and the second drive element 150 are at least partially exposed in the second opening 127. When viewed from the first direction D1, the first drive element fixing element 160, the second clamping portion 162, and the second drive element fixing element 170 near the fourth side 1004 are at least partially exposed in the third opening 128.

[0170] In some embodiments, the optical mechanism 100 further includes a third adhesive element 530 (only when the optical mechanism 100 includes a third adhesive element 530). Figure 24 (Shown schematically). A third adhesive element 530 is disposed between the third frame surface 113 and the fifth base surface 125, such that the frame 110 is fixedly connected to the base 120 via the third adhesive element 530. The third frame surface 113 faces the fifth base surface 125, and the third frame surface 113 and the fifth base surface 125 are not parallel. Either the third frame surface 113 or the fifth base surface 125 is parallel to the first axis A1. That is, one of the third frame surface 113 or the fifth base surface 125 is parallel to the first axis A1, but the other of the third frame surface 113 or the fifth base surface 125 is inclined relative to the first axis A1. Therefore, a space for accommodating the third adhesive element 530 can be formed between the third frame surface 113 and the fifth base surface 125 to strengthen the connection between the frame 110 and the base 120.

[0171] It should be noted that the first adhesive element 510, the second adhesive element 520, and the third adhesive element 530 can be made of the same or different materials. The first adhesive element 510, the second adhesive element 520, and the third adhesive element 530 can be adhesive materials, conductive materials, or insulating materials, such as resin materials, optical adhesives, etc. The first adhesive element 510, the second adhesive element 520, and the third adhesive element 530 can adhere to different components, strengthening the connection between the components. In addition, the first adhesive element 510, the second adhesive element 520, and the third adhesive element 530 generally have good elasticity and covering force. Applying the first adhesive element 510, the second adhesive element 520, and the third adhesive element 530 to the components can protect the components and reduce the probability of dust, moisture, and other impurities entering the components. If the first adhesive element 510, the second adhesive element 520, and the third adhesive element 530 are insulating materials, they can achieve an insulating effect. The connection between the elements can be strengthened by applying the first adhesive element 510, the second adhesive element 520, and the third adhesive element 530. Therefore, the overall structural strength of the optical mechanism 100 can be improved.

[0172] In summary, the first and second driving elements can be controlled independently to achieve greater design flexibility and high stability and precision. The attraction between the first and second magnetic elements and the magnetically conductive element ensures close contact between the first and second guiding elements and the moving part. The first and second guiding elements ensure the moving part's range of motion in a specific dimension and prevent unwanted wobbling, rotation, or tilting. Furthermore, the position of the moving part can be determined in real time by the sensing component. Based on the position of the moving part sensed by the sensing component, the first and second control units can correspondingly control the driving signals transmitted to the first and second driving elements to achieve closed-loop feedback. In addition, the elements can have corresponding configurations, including shapes and structures, and adhesive elements can be applied as needed to strengthen the connection between the elements, thereby enhancing the mechanical strength of the optical mechanism.
