Referring to FIG. 1, an optical member driving mechanism 10 according to an embodiment of the invention can be disposed in an electronic device 20. The optical member driving mechanism 10 can be configured to hold and drive an optical member 30, so that the optical member 30 can move relative to an image sensor (not shown) in the electronic device 20, and the purpose of focusing, zooming, and/or optical image stabilization (OIS) can be achieved. For example, the electronic device 20 can be a smartphone, a tablet computer, or a digital camera, and the optical member 30 can be a camera lens with a plurality of lenses, but it is not limited thereto.

FIG. 2 is a schematic diagram of the optical member driving mechanism 10, and FIG. 3 is an exploded-view diagram of the optical member driving mechanism 10. As shown in FIG. 2 and FIG. 3, the optical member driving mechanism 10 primarily includes a fixed portion 100, a movable portion 200, and a driving assembly 300.

The fixed portion 100 includes a housing 110 and a base 120. The housing 110 and a base 120 can be engaged with each other to form a hollow box. The movable portion 200 and the driving assembly 300 can be accommodated in the hollow box. The housing 110 includes a top wall 111 and a plurality of lateral walls 112 connected to the top wall 111. One or more soft pads 113 are attached on the outer surface of each lateral wall 112, so as to prevent from the damage caused by the impact between the optical member driving mechanism 10 and the other members in the electronic device 20 when the electronic device 20 oscillates. When viewed along the main axis AX of the optical member driving mechanism 10 (i.e. the optical axis of the optical member 30, that is parallel to the Z-axis in the figures), the fixed portion 100 has a polygonal structure.

In this embodiment, when viewed along the main axis AX of the optical member driving mechanism 10, the fixed portion 100 has a rectangular structure including a first side 101, a second side 102, a third side 103, and a fourth side 104. The first side 101 is opposite the second side 102, the third side 103 and the fourth side 104 are situated between the first side 101 and the second side 102, and the third side 103 is opposite the fourth side 104. The junction of the first side 101 and the third side 103 forms a first corner C1, the junction of the first side 101 and the fourth side 101 forms a second corner C2, the junction of the second side 102 and the third side 103 forms a third corner C3, and the junction of the second side 102 and the fourth side 104 forms a fourth corner C4.

The movable portion 200 is configured to connect the optical member 30, and is movably connected to the fixed portion 100. In this embodiment, the movable portion 200 is movable relative to the fixed portion 100 along the main axis AX. In some embodiments, the movable portion is movable relative to the fixed portion 100 along a direction that is perpendicular to the main axis AX.

The driving assembly 300 can drive the movable portion 200 to move relative to the fixed portion 100. In detail, in this embodiment, the driving assembly 300 includes a first magnetic member 310, a second magnetic member 320, a first coil 340, and a second coil 350. The first magnetic member 310 and the second magnetic member 320 are affixed to the base 120 or the lateral walls 112 of the fixed portion 100, and respectively disposed on the third side 103 and the fourth side 104 of the fixed portion 100. The first coil 340 and the second coil 350 are disposed on the movable portion 200, and respectively correspond to the first magnetic member 310 and the second magnetic member 320.

When current flows through the first coil 340, an electromagnetic force can be generated between the first coil 340 and the first magnetic member 310 to push the movable portion 200 to move relative to the fixed portion 100 along the main axis AX. Similarly, when current flows through the second coil 350, an electromagnetic force can be generated between the second coil 350 and the second magnetic member 320 to push the movable portion 200 to move relative to the fixed portion 100 along the main axis AX. Therefore, the purpose of focusing, zooming, and/or optical image stabilization can be achieved.

In this embodiment, the driving assembly 300 further includes one or more permeability members 360. The permeability members 360 are embedded in the lateral walls 112 of the fixed portion 100, and enclose the surfaces of the first magnetic member 310 besides the surface facing the first coil 340 and the surfaces of the second magnetic member 320 besides the surface facing the second coil 350, so that the driving force of the driving assembly 300 can be enhanced.

FIG. 4 is a cross-sectional view taken along the line A-A in FIG. 2. As shown in FIG. 2 to FIG. 4, in this embodiment, the optical member driving mechanism 10 includes a supporting assembly 400. The supporting assembly 400 includes a first intermediate member 410, a first corresponding member 420, a first forcing member 430, a first stabilizing member 440, a second intermediate member 450, a second corresponding member 460, a second forcing member 470, and a second stabilizing member 480.

The first intermediate member 410, the first corresponding member 420, the first forcing member 430, and the first stabilizing member 440 are disposed on the first side 101 of the fixed portion 100 and adjacent to the first corner C1 of the fixed portion 100. The first intermediate member 410 can be a cylinder affixed to the base 120, and the longitudinal axis of the cylinder is extended along a direction that is parallel to the main axis AX. The first corresponding member 420 is a recess formed on the surface of the movable portion 200 facing the lateral walls 112. The first intermediate member 410 can be accommodated in the first corresponding member 420 and movable relative to the first corresponding member 420.

The first forcing member 430 and the first stabilizing member 440 are respectively disposed on the movable portion 200 and the fixed portion 100. A first stabilizing force F1 can be formed therebetween and applied to the movable portion 200. For example, the first forcing member 430 can be a magnet, and the first stabilizing member 440 can include ferromagnetism material. Therefore, the magnetic attraction force between the first forcing member 430 and the first stabilizing member 440 can be used as the first stabilizing force F1. The movable portion 200 can lean against the first intermediate member 410 accordingly, and it can be ensured that the first intermediate member 410 is in contact with the first corresponding member 420.

In some embodiments, the first stabilizing member 440 can be a magnet, and the first forcing member 430 can include ferromagnetism material. In some embodiments, the first forcing member 430 and the first stabilizing member 440 are magnets attracting each other.

In this embodiment, when viewed from the main axis AX, the first stabilizing member 440 is closer to the first corner C1 than the first intermediate member 410. That is, the distance between the first stabilizing member 440 and the first corner C1 is less than the distance between the first intermediate member 410 and the first corner C1.

The second intermediate member 450, the second corresponding member 460, the second forcing member 470, and the second stabilizing member 480 are disposed on the second side 102 of the fixed portion 100 and adjacent to the fourth corner C4 of the fixed portion 100. The second intermediate member 450 can be a cylinder affixed to the base 120, and the longitudinal axis of the cylinder is extended along the direction that is parallel to the main axis AX. The second corresponding member 460 is a recess formed on the surface of the movable portion 200 facing the lateral walls 112. The second intermediate member 450 can be accommodated in the second corresponding member 460 and movable relative to the second corresponding member 460.

The second forcing member 470 and the second stabilizing member 480 are respectively disposed on the movable portion 200 and the fixed portion 100. A second stabilizing force F2 can be formed therebetween and applied to the movable portion 200. For example, the second forcing member 470 can be a magnet, and the second stabilizing member 480 can include ferromagnetism material. Therefore, the magnetic attraction force between the second forcing member 470 and the second stabilizing member 480 can be used as the second stabilizing force F2. The movable portion 200 can lean against the second intermediate member 450 accordingly, and it can be ensured that the second intermediate member 450 is in contact with the second corresponding member 460.

In some embodiments, the second stabilizing member 480 can be a magnet, and the second forcing member 470 can include ferromagnetism material. In some embodiments, the second forcing member 470 and the second stabilizing member 480 are magnets attracting each other.

In this embodiment, when viewed from the main axis AX, the second stabilizing member 480 is closer to the fourth corner C4 than the second intermediate member 450. That is, the distance between the second stabilizing member 480 and the fourth corner C4 is less than the distance between the second intermediate member 450 and the fourth corner C4.

Owing to the supporting assembly 400, when the driving assembly 300 drives the movable portion 200 to move relative to the fixed portion 100, the first intermediate member 410 and the second intermediate member 450 can guide the movable portion 200 to move along the main axis AX, so that the stability of movement of the movable portion can be increased.

Moreover, it should be noted that, when viewed along the main axis AX, the first corresponding member 420 and the second corresponding member 460 respectively has a V-shaped structure and U-shaped structure, so as to facilitated the assemble of the optical member driving mechanism 10.

As shown in FIG. 5A and FIG. 5B, in this embodiment, the first corresponding member 420 includes a first corresponding part 421, a second corresponding part 422, a first depression part 423, and a first receiving part 424. The first depression part 423 is disposed between the first corresponding part 421 and the second corresponding part 422. The first receiving part 424 is formed in the first depression part 423, so that it is also disposed between the first corresponding part 421 and the second corresponding part 422. When the movable portion 200 is connected to the fixed portion via the supporting assembly 400, the first corresponding part 421 and the second corresponding part 422 are in contact with the first intermediate member 410, and the first depression part 423 is spaced away from the first intermediate member 410.

The first receiving part 424 has a depression structure or an opening structure. The lead 341 of the first coil 340 can be extended along the surface of the movable portion 200 facing the lateral walls, and can be received in the first receiving part 424. Therefore, when the first movable portion 200 moves along the first intermediate member 410, the lead 341 of the first coil 340 does not interfere with the first intermediate member 41, and the damage of the lead 341 of the first coil 340 can be prevented.

Similarly, the supporting assembly 400 can include a second depression part 491 and a second receiving part 492 formed on the movable portion 200. At least a portion of the first forcing member 430 is accommodated in the second depression part 491. The second receiving part 492 is formed in the second depression part 491 and has a depression structure or an opening structure. The lead 341 of the first coil 340 can be received in the second receiving part 492, so as to prevent the lead 341 of the first coil 340 from the damage.

Referring to FIG. 2 to FIG. 5B, in this embodiment, the optical member driving mechanism 10 includes a position sensing assembly 500. The position sensing assembly 500 includes a sensing member 510, a reference member 520, a third depression part 530, and a third receiving part 540.

The sensing member 510 can be connected to the fixed portion 100, and the reference member 520 can be disposed ono the movable portion 200. The sensing member 510 can detect the movement of the reference member 520 to notice the position of the movable portion 200 relative to the fixed portion 100. For example, the sensing member 510 can be a Hall sensor, a magnetoresistance effect sensor (MR sensor), a giant magnetoresistance effect sensor (GMR sensor), a tunneling magnetoresistance effect sensor (TMR sensor), or a fluxgate sensor, and the reference member 520 can be a magnet, but it is not limited thereto.

The third depression part 530 is formed on the movable portion 200, and at least a portion of the reference member 520 is accommodated in the third depression part 530. The third receiving part 540 is formed in the third depression part 530 and has a depression structure or an opening structure. The lead 340 of the first coil 340 can be received in the third receiving part 540, so as to prevent the lead 341 of the first coil 340 from the damage.

In this embodiment, the first intermediate member 410 is disposed between the position sensing assembly 500 and the first forcing member 430, and the first forcing member 430 is closer to the first corner C1 than the sensing assembly 500. In other words, the first receiving part 424 is disposed between the second receiving part 492 and the third receiving part 540, and the distance between the first forcing member 430 and the first corner C1 is less than the distance between the position sensing assembly 500 and the first corner C1.

In some embodiments, the positions of the sensing member 510 and the reference member 520 can be interchanged. That is, the sensing member 510 can be disposed on the movable portion 200, and the reference member 520 can be disposed on the fixed portion 100 correspondingly.

FIG. 6 is a cross-sectional view taken along the line B-B in FIG. 2. As shown in FIG. 2, FIG. 3, and FIG. 6, in this embodiment, the optical member driving mechanism 10 includes at least one stopping assembly 600 configured to restrict the moving range of the movable portion 200. In particular, the stopping assembly 600 includes a first body 610, a second body 620, a stopping portion 630, and a reinforcing portion 640.

The first body 610 can be a part of the base 120, and it can include plastic, but it is not limited thereto. The first body 610 includes a first surface 611 facing the movable portion 200 and a second surface 612 facing the opposite direction. A first depression 611A is formed on the first surface 611, a second depression 612A is formed on the second surface 612, and the first depression 611A and the second depression 612A are communicated with each other.

The second body 620 is accommodated in the first depression 611A and the second depression 612A, and protrudes from the first surface 611 of the first body 610. For example, the second body 620 can include soft material (such as rubber, silicone gel, or foam, but it is not limited thereto), so that its Young's modulus can be less than the Young's modulus of the first body 610.

The stopping portion 630 can be a part of the movable portion 200 corresponding to the second body 620. When the driving assembly 300 drives the movable portion 200 to move toward the base 120 to an extreme position, the stopping portion 630 can be in contact with the second body 620. Therefore, the stopping assembly 600 can restrict the moving range of the movable portion 200, and the impact between the movable portion 200 and the fixed portion 100 can be prevented.

The reinforcing portion 640 can be embedded in the base 120 and have a receiving portion 641. The position of the receiving portion 641 corresponds to the position of the first depression 611A and the position of the second depression 612A, so that at least a portion of the receiving portion 641 is exposed from the first depression 611A and the second depression 612A. The receiving portion 641 has an opening structure, and at least a portion of the second body 620 is disposed in the opening structure of the receiving portion 641. The reinforcing portion 640 includes metal, so that its Young's modulus can be greater than the Young's modulus of the first body 610 and the second body 620. Furthermore, at least a portion of the reinforcing portion 640 is embedded in the second body 620. Therefore, with the aforementioned arrangement, it is facilitated to position the second body 620, and the displacement of the second body 620 when the stopping portion 620 is in contact with the second body 620 can be prevented.

In this embodiment, the second body 620 has a third surface 620 and a fourth surface 622. The third surface 621 and the first surface 611 face the same direction, and the fourth surface 622 and the second surface 612 face the same direction. In a direction that is perpendicular to the first surface 611 (i.e. the direction parallel to the main body AX), the shortest distance D1 between the first surface 611 and the third surface 621 is less than the shortest distance D2 between the second surface 312 and the fourth surface 622.

Moreover, in this embodiment, the second body 620 is not in contact with the first body 610, and the gaps between the first body 610 and the second body 620 on the opposite sides of the reinforcing portion 640 are different. In detail, the first surface 610 has a fifth surface 613, and the second body 620 has a sixth surface 623. The fifth surface 613 and the sixth surface 623 face each other, and the sixth surface 623 is connected to the third surface 621 (that is, the fifth surface 613 and the sixth surface 623 are disposed above the reinforcing portion 640). A first gap G1 is formed between the fifth surface 613 and the sixth surface 623. The first body 610 further has a seventh surface 614, and the second body 620 further has an eighth surface 624. The seventh surface 614 and the eighth surface 624 face each other, and the eighth surface 624 is connected to the fourth surface 622 (that is, the seventh surface 614 and the eighth surface 624 are disposed below the reinforcing portion 640). A second gap G2 is formed between the seventh surface 614 and the eighth surface 624, and the second gap G2 is different from the first gap G1. For example, the second gap G2 is greater than the first gap G1.

In some embodiments, the reinforcing portion 640 can be electrically connected to the driving assembly 300 and/or the position sensing assembly 500, so as to facilitate the transmission of the current or the signal.

As shown in FIG. 6, in this embodiment, the optical member driving mechanism 10 can further include a connecting member 700. The connecting member 700 is disposed in the second depression 612A and in direct contact with the first body 610, the second body 620, and the reinforcing portion 640. For example, the connecting member 700 can be a non-conductive light-curing glue or a non-conductive thermal-curing glue. When the connecting member 700 is cured, it can be coplanar with the second surface 612. The defects in the optical member driving mechanism 10 caused by thermal expansion of the air in the second depression 612A during the assembly process can be therefore avoided.

Referring to FIG. 2, FIG. 3, and FIG. 7, in this embodiment, the optical member driving mechanism 10 further includes an elastic assembly 800. The elastic assembly 800 is connected to the fixed portion 100 and the movable portion 200 to hang the movable portion 200 in the hollow box of the fixed portion 100, and is electrically connected to the driving assembly 300.

When viewed along the main axis AX, the fourth fixed portion connecting end 841 does not overlap the supporting assembly 400, and the fourth movable portion connecting end 842 does not overlap the driving assembly 300.

It should be noted that, each of the first movable portion connecting end 812, the second movable portion connecting end 822, the third movable portion connecting end 832, and the fourth movable portion connecting end 842 is electrically connected to the first coil 340 and/or the second coil 350, and the first elastic member 810, the second elastic member 820, the third elastic member 830, and the fourth elastic member 840 are electrically independent of each other.
