[0115] Please refer to the following as well. Figure 6 . Figure 6 A perspective view of the third active element 130 of the optical element drive mechanism 1, based on certain features of this disclosure.

[0116] The third movable element 130 is movably connected to the fixed part 200 via the guide assembly 400. The third movable element 130 is movable relative to the second movable element 120 and the fixed part 200. The third movable element 130 has third guide grooves 131, 132, 133, 134, 135, 136 and a third movable element opening 137.

The movement of the third movable element 130 can drive the movement of the first movable element 110, the second movable element 120, and the fourth movable element 140. When the third movable element 130 moves, the second movable element 120 does not drive the fourth movable element 140 to move.

[0117] Please continue to refer to the following: Figure 3A as well as Figure 3B The fixing part 200 includes a housing 210, a base 220, and a frame 230. The housing 210 has a housing opening 212. The housing 210 and the base 220 are fixedly connected. The base 220 has an adjacent first side 221, a second side 222, and a base opening 223. The base 220 and the housing 210 form a first receiving space to receive the first movable element 110 and the circuit assembly 500. The frame 230 has an opening 232. The frame 230 and the housing 210 form a second receiving space to receive a first circuit element 510 of the circuit assembly 500.

[0118] The first movable element 110 and the first circuit element 510 are located on opposite sides of the frame 230. That is, the first movable element 110 is located on the side of the frame 230 facing the base 220, while the first circuit element 510 is located on the side of the frame 230 facing away from the base 220. And when viewed along the optical axis O1, the first movable element 110 and the first circuit element 510 at least partially overlap.

[0119] The drive assembly 300 includes a first drive unit 310, a second drive unit 320, and a third drive unit 330. The first drive unit 310 may be a drive unit such as a magnet and coil, a piezoelectric element, a stepper motor, or a shape memory alloy. In this embodiment, the first drive unit 310 includes two first magnetic elements 312 and two first coils 314. The first magnetic elements 312 are at least partially fixedly disposed on the second movable element 120. The first coils 314 correspond to the first magnetic elements 312. The first coils 314 are fixedly disposed on a second circuit element 520 of the circuit assembly 500 for connection to the second circuit element 520.

[0120] The electromagnetic driving force generated between the first magnetic element 312 and the first coil 314 causes the first magnetic element 312 to move relative to the first coil 314. Consequently, the second movable element 120 moves relative to the second circuit element 520, and the second movable element 120 drives the first movable element 110 and the optical element 10 to move. Therefore, the electromagnetic driving force generated between the first magnetic element 312 and the first coil 314 can drive the second movable element 120 to move the first movable element 110 and the optical element 10 relative to the fixed part 200.

[0121] The second driving unit 320 may be, for example, a driving unit consisting of a magnet and coil, a piezoelectric element, a stepper motor, or a shape memory alloy. In this embodiment, the second driving unit 320 includes a second magnetic element 322 and a second coil 324. The second magnetic element 322 is at least partially fixedly disposed on the third movable element 130. The second coil 324 corresponds to the second magnetic element 322. The second coil 324 is fixedly disposed on the second circuit element 520 of the circuit assembly 500 for connection with the second circuit element 520.

[0122] The electromagnetic driving force generated between the second magnetic element 322 and the second coil 324 causes the second magnetic element 322 to move relative to the second coil 324. Consequently, the third movable element 130 moves relative to the second circuit element 520, and the third movable element 130 drives the first movable element 110, the second movable element 120, and the optical element 10 to move relative to the fixed part 200, thus allowing the third movable element 130 and the second movable element 120 to move relative to the second coil 324.

[0123] The third drive unit 330 may be a drive unit such as a magnet and coil, a piezoelectric element, a stepper motor, or a shape memory alloy. In this embodiment, the third drive unit 330 includes two third magnetic elements 332 and two third coils 334. The third magnetic elements 332 are at least partially fixedly disposed on the fourth movable element 140. The third coils 334 correspond to the third magnetic elements 332. The third coils 334 are fixedly disposed on the second circuit element 520 of the circuit assembly 500 for connection with the second circuit element 520.

[0124] The electromagnetic driving force generated between the third magnetic element 332 and the third coil 334 causes the third magnetic element 332 to move relative to the third coil 334. Consequently, the fourth movable element 140 moves relative to the second circuit element 520, and the fourth movable element 140 drives the first movable element 110 and the optical element 10 to move. Therefore, the electromagnetic driving force generated between the third magnetic element 332 and the third coil 334 can drive the fourth movable element 140 to move the first movable element 110 and the optical element 10 relative to the fixed part 200, allowing the fourth movable element 140 and the first movable element 110 to move relative to the third coil 334.

[0125] The multiple drives of the first coil 314, the second coil 324, the third coil 334, the first magnetic element 312, the second magnetic element 322, and the third magnetic element 332 of the drive assembly 300 allow adjustment of the optical photographic focal length of the optical element 10 to adapt to different external photographic needs, and provide sufficient driving force to drive the first movable element 110, the second movable element 120, the third movable element 130, the fourth movable element 140, and the optical element 10.

[0126] The guide assembly 400 connects the first movable element 110, the second movable element 120, the third movable element 130, and the fourth movable element 140. The guide assembly 400 has a first guide portion 410, a second guide portion 420, and a third guide portion 430. The first guide portion 410 corresponds to the connection between the first movable element 110 and the second movable element 120 and the fourth movable element 140. The second guide portion 420 corresponds to the connection between the first movable element 110 and the second movable element 120, and the fourth movable element 140 and the third movable element 130. The third guide portion 430 corresponds to the connection between the third movable element 130 and the fourth movable element 140, and the second movable element 120.

Figure 7 A perspective view of the first circuit element 510 of the optical element drive mechanism 1, according to certain features of this disclosure. Figure 8 For illustrative purposes, a perspective view of the optical element drive mechanism 1 is provided, with the housing 210 removed, in accordance with certain features of this disclosure.

[0129] The circuit assembly 500 is used to connect to an external circuit (not shown, for example, an output circuit for the optical element driving mechanism 1). The circuit assembly 500 includes a first circuit element 510 and a second circuit element 520.

[0130] A first circuit element 510 is disposed on the frame 230 of the fixed portion 200. The first circuit element 510 includes a movable end 511, a fixed end 512, a plate-shaped body 513, a flexible portion 514, and a first circuit element opening 515. The fixed end 512 is at least partially fixedly connected to the base 220 of the fixed portion 200. The movable end 511 is at least partially fixedly connected to the first movable element 110. The movable end 511 is movably connected to the fixed end 512 via the flexible portion 514 and the plate-shaped body 513. When the first movable element 110 is in an extreme position, for example, when it moves to the bottom of the movable range in the second dimension D2, the flexible portion 514 does not fully contact the frame 230.

[0131] The movable end 511 includes a first connecting portion 511-1, a second connecting portion 511-2, a third connecting portion 511-3, and a fourth connecting portion 511-4. The second connecting portion 511-2 is located between the first connecting portion 511-1 and the third connecting portion 511-3. The first connecting portion 511-1, the second connecting portion 511-2, the third connecting portion 511-3, and the fourth connecting portion 511-4 are used to electrically connect to an optical element module (e.g., any electronic module such as a variable aperture, lens actuator, photosensitive element actuator, vibration motor, fingerprint recognition, etc.). The first connecting portion 511-1, the second connecting portion 511-2, the third connecting portion 511-3, and the fourth connecting portion 511-4 are electrically connected to the fixed end 512 via a flexible portion 514.

[0132] When viewed along the optical axis O1, the first connecting portion 511-1, the second connecting portion 511-2, the third connecting portion 511-3, and the fourth connecting portion 511-4 are arranged along a straight line parallel to the first side 221. The flexible portion 514 extends around the optical axis O1 by at least 180 degrees. Preferably, the flexible portion 514 extends around the optical axis O1 by more than 270 degrees.

[0133] The second circuit element 520 is disposed on the base 220 of the fixing part 200. The second circuit element 520 has an external connection terminal 522 for outputting electrical signals of the optical element driving mechanism 1. The external connection terminal 522 is at least partially fixedly connected to the fixing part 200. The external connection terminal 522 and the fixing end 512 of the first circuit element 510 are located between the second side 222 and the housing 210. The external connection terminal 522 and the fixing end 512 each have multiple connection portions, which are arranged parallel to the second side 222.

[0134] Please refer to the following: Figure 9 as well as Figure 10 . Figure 9 A perspective view of the reinforcing component 600 of the optical element drive mechanism 1, based on certain features of this disclosure. Figure 10 A perspective view of the reinforcing component 600 and the driving component 300 of the optical element driving mechanism 1, based on certain features of this disclosure.

[0135] The reinforcing component 600 is at least partially fixedly disposed on the first movable element 110. The reinforcing component 600 includes a first reinforcing element 610, a second reinforcing element 620, a third reinforcing element 630, a fourth reinforcing element 640, and a fifth reinforcing element 650. When viewed along the optical axis O1, the first reinforcing element 610 and the second reinforcing element 620 at least partially overlap, the first reinforcing element 610 and the third reinforcing element 630 do not overlap, and the second reinforcing element 620 and the third reinforcing element 630 at least partially overlap. When viewed along the normal direction (perpendicular to the optical axis O1) of the surface of the first side 221 of the base 220, the third reinforcing element 630 located on the opposite side of the first side 221 at least partially overlaps with the first reinforcing element 610, and the third reinforcing element 630 located on the opposite side of the first side 221 does not overlap with the second reinforcing element 620.

[0136] The first reinforcing element 610 is disposed on the first movable element 110 and can be a magnetic sheet made of metal. The second reinforcing elements 620 are disposed on the first magnetic element 312 and the third magnetic element 332, respectively, and are L-shaped and made of metal. The second reinforcing elements 620 correspond to the drive assembly 300. The attraction between the first magnetic element 312 and the third magnetic element 332 and the second reinforcing elements 620 exerts opposite forces on the first magnetic element 312 and the third magnetic element 332, preventing the internal structure of the optical element drive mechanism 1 from overturning due to excessive magnetic force from the first magnetic element 312 and the third magnetic element 332.

[0137] The first reinforcing element 610 is movable relative to the second reinforcing element 620. The second reinforcing element 620 is at least partially located between the first reinforcing element 610 and the first magnetic element 312 of the drive assembly 300. The third reinforcing element 630 is made of metal but does not have magnetic permeability. The third reinforcing element 630 is connected to the first reinforcing element 610. The recessed structure of the third reinforcing element 630 corresponds to the first reinforcing element 610 and the third magnetic element 322. In this embodiment, the magnetic permeability of the first reinforcing element 610 is greater than that of the third reinforcing element 630. In some embodiments, the first reinforcing element 610 and the second reinforcing element 620 may have different magnetic permeability. In other embodiments, the first reinforcing element 610 and the second reinforcing element 620 may have the same magnetic permeability.

[0138] Next, please continue to refer to the following: Figure 3A as well as Figure 3BThe fifth reinforcing element 650 is disposed between the second magnetic element 322 and the fourth movable element 140, and the fourth reinforcing element 640 is disposed between the second coil 324 and the housing 210 to prevent magnetic field interference. The reinforcing assembly 600 stabilizes the internal structure of the optical element drive mechanism 1 and reduces operational errors of the drive assembly 300 during operation.

[0139] The sensing assembly 700 includes a first sensing element 710, a second sensing element 720, and a third sensing element 730. The first sensing element 710, the second sensing element 720, and the third sensing element 730 are all disposed within the second circuit element 520. The first sensing element 710 is disposed between the first coils 314 to sense the movement of the second movable element 120. The second sensing element 720 is disposed between the third coils 334 to sense the movement of the fourth movable element 140. The third sensing element 730 is disposed within the second coils 324 to sense the movement of the third movable element 130.

[0140] In the optical element drive mechanism 1, the optical axis O1 passes sequentially through the optical element 10, the housing opening 212, the first circuit element opening 515, the frame opening 232, the fifth movable element opening 152, the first movable part opening 117, the third movable element opening 137, and the base opening 223, thereby passing through the entire optical element drive mechanism 1.

[0141] Please refer to the following as well. Figures 11 to 12 . Figure 11 For the purposes of illustration, a perspective view of the optical element drive mechanism 1 is provided, in accordance with certain features of this disclosure. The fixing part 200 is removed, and the first moving element 110 is indicated by dashed lines.

[0142] Figure 12 For the purposes of illustration, a perspective view of the optical element drive mechanism 1 is provided, in accordance with certain features of this disclosure. The fixed part 200 and the first movable element 110 are removed, and the second movable element 120 and the fourth movable element 140 are indicated by dashed lines.

[0143] The first guide portion 410 is movably connected to the second movable element 120, the fourth movable element 140, and the first movable element 110. The second movable element 120 and the fourth movable element 140 drive the first movable element 110 to move via the first guide portion 410.

[0144] The second guide 420 is movably connected to the second movable element 120, the fourth movable element 140, the first movable element 110, the third movable element 130, and the base 220 of the fixing part 200. The third movable element 130 is driven to move in the second dimension D2 via the second guide 420.

[0145] The third guide portion 430 is movably connected to the second movable element 120, the fourth movable element 140, and the third movable element 130. The second movable element 120 moves in the first dimension D1 via the third guide portion 430. The fourth movable element 140 moves in the third dimension D3 via the third guide portion 430.

[0146] In this embodiment, the first guide portion 410 is in the form of a sphere. The first guide grooves 111, 112, 113 and the second guide grooves 121, 122, 123 have elongated structures extending in the third dimension D3, allowing the sphere of the first guide portion 410 to move in the third dimension D3 when each of the first guide grooves 111, 112, 113 and the second guide grooves 121, 122, 123 is located within them. Since the sphere of the first guide portion 410 has almost no room to move in the first dimension D1, when the second movable element 120 moves in the first dimension D1, the first movable element 110 is driven to move by the first guide grooves 111, 112, 113. Conversely, since the sphere of the first guide portion 410 can move in the third dimension D3, when the first movable element 110 moves in the third dimension D3, the second movable element 120 is not driven to move by the first movable element 110.

[0147] The second guide grooves 124, 125, 126 and the third guide grooves 131, 132, 133 have elongated structures extending in the first dimension D1, such that when the ball of the third guide portion 430 is located within the second guide grooves 124, 125, 126 and the third guide grooves 131, 132, 133, it can move in the first dimension D1. Therefore, when the second movable element 120 is driven by the first magnetic element 312 and the first coil 314, it can move relative to the third movable element 130 in the first dimension D1.

[0148] The first guide grooves 114, 115, 116 and the fourth guide grooves 141, 142, 143 have elongated structures extending in the first dimension D1, such that when the ball of the first guide portion 410 is located within the first guide grooves 114, 115, 116, it can move in the first dimension D1. Since the ball of the first guide portion 410 has almost no room to move in the third dimension D3, when the fourth movable element 140 moves in the third dimension D3, the first movable element 110 is driven to move by the third guide portion 430. Conversely, since the ball of the first guide portion 410 can move in the first dimension D1, when the first movable element 110 moves in the first dimension D1, the fourth movable element 140 is not driven to move by the first movable element 110.

[0149] The fourth guide grooves 144, 145, 146 and the third guide grooves 134, 135, 136 have elongated structures extending in the third dimension D3, such that when the ball of the third guide portion 430 is located within the fourth guide grooves 144, 145, 146 and the third guide grooves 134, 135, 136, it can move in the third dimension D3. Therefore, when the fourth movable element 140 is driven by the third magnetic element 332 and the third coil 334, it can move relative to the third movable element 130 in the third dimension D3.

[0150] The second guide section 420 consists of two guide rods. When the third movable element 130 is driven by the second magnetic element 322 and the second coil 324, it can move relative to the base 220 of the fixed part 200 in the second dimension D2 via the two second guide sections 420.

[0151] When the second movable element 120 moves in the first dimension D1, the second movable element 120 drives the first movable element 110 to move.

[0152] When the first movable element 110 moves in the third dimension D3, the first movable element 110 hardly drives the second movable element 120 to move.

[0153] In another embodiment, the first guide portion 410 and the third guide portion 430 may be in the form of a reed (not shown). In this configuration, the first guide portion 410 and the third guide portion 430 are separate reeds, which are individually connected to the first movable element 110, the second movable element 120, the third movable element 130 and the fourth movable element 140.

[0154] In summary, this invention provides an optical element driving mechanism, comprising a plurality of movable elements, a fixed part, a driving assembly, a circuit assembly, a guiding assembly, and a sensing assembly. The movement of the driving assembly causes the plurality of movable elements to move relative to each other and to the fixed part. This allows adjustment of the position of the optical element to adapt to different photographic needs, providing more stable optical quality. Furthermore, since the first circuit element of the circuit assembly is flexible and can be connected to the movable part, this invention eliminates the need for complex circuit wiring and corresponding structures on the movable part for electrical connection with the fixed part, thus achieving cost reduction, simplified overall structure, and simplified circuit design.
