Detailed Description

Please refer to fig. 1 to 10. The image capturing apparatus with an anti-shake function (hereinafter referred to as image capturing apparatus 100) of some embodiments of the present application includes a housing 200, a lens assembly 300, a sensor carrier 400, a first movable structure 500, a second movable structure 600, a first coil group 720, a second coil group 710, a magnetic assembly 730, and a plurality of balls 750.

The housing 200 includes a cover 210 and a base 220. The bottom plate 220 is coupled to the cover 210 to form a housing having a receiving space therein. The lens assembly 300 is embedded on the cover 210. Specifically, the lens assembly 300 is hermetically connected to the cover 210, so that external dust, moisture or particles cannot easily enter the housing 200 through this configuration. For example, the cover 210 has an opening on a side opposite to the bottom plate 220, and the opening is matched with the lens assembly 300. In other words, the lens assembly 300 can be assembled on the opening of the cover 210, and a sealing member (e.g., a sealing gasket, a sealant, a packing, etc.) is interposed between the lens assembly 300 and the cover 210. The structural components of the lens assembly 300 are well known in the art, and thus will not be described again (only the main body of the lens assembly 300 is schematically shown in the drawings).

The sensor carrier 400 is located within the housing 200 and aligned with the lens assembly 300. In some embodiments, the sensor carrier 400 is a thermal curable adhesive (TSA) flexible circuit board or a flexible printed circuit board (FPC).

The first movable structure 500 is disposed on the sensor carrier 400 and is movably disposed on the housing 200 via the balls 750. In other words, the first movable structure 500 and the bottom plate 220 sandwich a plurality of balls 750. With this arrangement, the first movable structure 500 can be more smoothly displaced with respect to the base plate 220.

The first movable structure 500 has a limit groove 520. The limiting groove 520 is located between the lens assembly 300 and the sensor carrier 400. The notch 521 of the limiting groove 520 is adjacent to the lens assembly 300 (i.e., the notch 521 faces upward as viewed in fig. 3), and the groove bottom 522 of the limiting groove 520 has an opening 530.

The second movable structure 600 is located in the limiting groove 520, and is fixed on the sensor carrier 400 through the opening 530 of the first movable structure 500. Here, the second movable structure 600 has a sensing window 621 having a size smaller than or equal to the opening 530, and the sensing window 621 is aligned with the lens assembly 300 and overlaps the opening 530.

The magnetic component 730 is disposed on the first movable structure 500 and is located around the limit slot 520. Specifically, the magnetic component 730 is fixed on a sidewall of the limit slot 520. In some embodiments, the magnetic assembly 730 includes a plurality of magnets 731, and the magnets 731 are respectively positioned around the limiting slot 520 in different orientations. For example, the limiting groove 520 is a rectangular groove, the magnetic component 730 is four magnets 731, and the four magnets 731 are respectively fixed on four sidewalls of the limiting groove 520.

The first coil set 720 is disposed on the sensor carrier 400 and corresponds to the magnetic assembly 730. After the image capturing apparatus 100 is assembled, the magnetic assembly 730 is located on the first coil assembly 720, and a first gap is formed between the magnetic assembly 730 and the first coil assembly 720. In other words, the magnetic assembly 730 and the first coil block 720 do not directly contact each other.

The second coil assembly 710 is disposed on the second movable structure 600 and corresponds to the magnetic assembly 730. After the image capturing apparatus 100 is assembled, the second coil assembly 710 is located between the second movable structure 600 and the magnetic component 730, and a second gap is provided between the second coil assembly 710 and the magnetic component 730. In other words, the second coil assembly 710 and the second movable structure 600 are located together in the limiting slot 520, and the second coil assembly 710 does not directly contact the magnetic component 730.

With the above arrangement, the second movable structure 600 is configured to move in a first direction (i.e., a direction parallel to the surface of the sensor carrier 400, or a direction perpendicular to the optical axis of the image capturing apparatus 100) due to the Lorentz force (Lorentz force) between the second coil group 710 and the magnetic component 730, and the first movable structure 500 is configured to move in a second direction (i.e., a direction perpendicular to the surface of the sensor carrier 400, or a direction parallel to the optical axis of the image capturing apparatus 100) due to the Lorentz force between the first coil group 720 and the magnetic component 730. Wherein the first direction is perpendicular to the second direction. In other words, when the first coil assembly 720 is energized during use, a lorentz force is generated between the first coil assembly 720 and the magnetic component 730, so as to correspondingly adjust the distance between the first movable structure 500 and the sensor carrier 400 in the second direction. Similarly, by energizing the second coil assembly 710, a lorentz force is generated between the second coil assembly 710 and the magnetic assembly 730, thereby correspondingly adjusting the position of the first movable structure 500 relative to the second movable structure 600 in the first direction.

In some embodiments, the sensor carrier 400 includes an outer frame plate 410, a carrier plate 420, an inner frame plate 440, inner connection wires 430, and outer connection wires 450. The outer frame plate 410 is provided on the housing 200. In some embodiments, the bottom plate 220 has a cavity 221 inside, and the outer frame plate 410 is disposed on the bottom plate 220 along an edge of the cavity 221.

The receiving plate 420 corresponds to the lens assembly 300 and is located inside the outer frame plate 410. The inner frame plate 440 is located between the outer frame plate 410 and the receiving plate 420. The interconnection 430 is connected between the inner frame plate 440 and the receiving plate 420 such that the receiving plate 420 can be displaced/rotated relative to the inner frame plate 440. The outer connection line 450 is connected between the inner frame plate 440 and the outer frame plate 410 such that the inner frame plate 440 can be displaced/rotated with respect to the outer frame plate 410.

Here, the first movable structure 500 is fixed to the inner frame plate 440. The second movable structure 600 is fixed to the receiving plate 420 through the opening 530 of the first movable structure 500. The first coil group 720 is fixed to the outer frame plate 410.

In some embodiments, the sensor carrier 400 may further comprise a connection plate 460, and the connection plate 460 is connected to the outer side of the outer frame plate 410. In other words, the inner frame plate 440 and the connection plate 460 are respectively connected to opposite sides of one side of the outer frame plate 410. Here, the connection board 460 provides connection of the image pickup apparatus 100 with external signals and/or power.

In some embodiments, the image capturing apparatus 100 may further include a sensor die 920 and a package 930. The sensor wafer 920 is located between the receiving plate 420 and the lens assembly 300. Here, the sensor wafer 920 is aligned with the sensing window 621 and is fixed on the receiving plate 420. The package structure 930 encapsulates the sensor die 920 on the carrier plate 420. In some embodiments, the outer frame plate 410, the receiving plate 420, the inner frame plate 440, the inner connection wires 430, the outer connection wires 450, and the connection plates 460 are distributed with conductive traces. One end of the conductive trace is located on the receiving plate 420 and is coupled to the sensor die 920 by wire bonding or flip chip technology. The conductive traces extend from the carrier plate 420, along the interconnect 430, the inner frame plate 440, the outer interconnect 450, and the outer frame plate 410, to the connection plate 460. The other end of the conductive line is located at the other side of the connection plate 460 opposite to the outer frame plate 410 so as to be connected with external components of the image capturing apparatus 100, thereby receiving external signals and/or power. Here, the package structure 930 encapsulates the sensor die 920 together with the conductive traces on the carrier 420 at one end (including the connection elements such as wires or solder materials) coupled to the sensor die 920.

In some embodiments, the image capturing apparatus 100 may further include a filter 910. The optical filter 910 is located between the lens assembly 300 and the package structure 930, and the optical filter 910 overlaps the sensing window 621. In some embodiments, the size of the filter 910 may be substantially equal to the size of the sensing window 621. For example, the filter 910 may be snapped into the sensing window 621. In another example, the second movable structure 600 has a notch along the periphery of the sensing window 621, and the periphery of the optical filter 910 is located in the notch and fixed on the second movable structure 600, so that the optical filter 910 covers the entire sensing window 621.

In some embodiments, the image capturing apparatus 100 may further include one or more stiffener plates (e.g., stiffener plate 470 and/or stiffener plate 480). In an example, the image capturing apparatus 100 has a reinforcing plate 470, and the reinforcing plate 470 is located between the other side of the receiving plate 420 opposite to the lens assembly 300 and the bottom plate 220 of the housing 200, and the receiving plate 420 is fixed on the reinforcing plate 470. In other words, the reinforcing plate 470 is disposed below the receiving plate 420 and is adhered to the lower surface of the receiving plate 420. Here, the reinforcing plate 470 has a certain strength to provide the supporting force to the receiving plate 420, thereby helping to avoid deformation of the receiving plate 420. In another example, the image pickup apparatus 100 has two reinforcing plates 470, 480 (hereinafter referred to as a first reinforcing plate 470 and a second reinforcing plate 480, respectively) as an example. The first reinforcing plate 470 is located between the other side of the receiving plate 420 opposite to the lens assembly 300 and the housing 200. The second reinforcing plate 480 has a concave portion 481 corresponding to the receiving plate 420 and a frame portion 482 surrounding the concave portion 481. The receiving plate 420 is fixed to the first reinforcing plate 470, so that the first reinforcing plate 470 can reinforce the receiving plate 420. The inner frame plate 440 is fixed to the frame portion 482 of the second reinforcement plate 480, and thus the frame portion 482 of the second reinforcement plate 480 can play a reinforcing role for the inner frame plate 440. The first reinforcing plate 470 is located in the recess 481 of the second reinforcing plate 480. In some embodiments, the size of the first stiffener plate 470 corresponds to the size of the outer contour of the socket plate 420. In some embodiments, the size of the second reinforcement plate 480 corresponds to the size of the outer profile of the inner frame plate 440.

In some embodiments, the edge of the outer frame plate 410 has a plurality of notches 411, and the first movable structure 500 is disposed on the bottom plate 220 of the housing 200 through the plurality of notches 411 of the outer frame plate 410.

In some embodiments, referring to fig. 2, 3, 7 and 8, the first movable structure 500 includes a main body 510, a plurality of support columns 550 and a fixing member 560. The body 510 has a first surface (i.e., an upper surface) and a second surface (i.e., a lower surface) opposite to each other. The first surface is adjacent to the lens assembly 300 with respect to the second surface and has the aforementioned limiting groove 520. The inner side wall of the main body 510 adjacent to the limiting groove 520 has a plurality of notches 540, and the notches 540 are used for accommodating the magnetic component 730. The support columns 550 correspond to the notches 411 of the outer frame plate 410, and protrude from the second surface of the main body 510.

One end of each support column 550 is connected to the second surface of the body 510. The other end of each support column 550 is movably connected to the housing 200 through a corresponding notch 411. The other end of each support column 550 has a recess 551 in the end face. Here, the balls 750 are respectively located in the concave holes 551 of the support columns 550. Specifically, the plurality of notches 411 and the plurality of support columns 550 correspond to the plurality of balls 750 one to one. Each ball 750 is sandwiched between the corresponding support column 550 and the bottom plate 220 of the housing 200 through the corresponding notch 411, and is located in the concave hole 551 of the corresponding support column 550. In other words, each ball 750 is also located in the corresponding notch 411.

The fixing members 560 are located at the periphery of the opening 530 and are connected between the second surface of the main body 510 and the inner frame plate 440. Specifically, the fixing member 560 protrudes from the second surface of the main body 510. Here, the first movable structure 500 is fixed to the inner frame plate 440 by the fixing member 560.

In some embodiments, the height of the fixtures 560 may be slightly greater than or equal to the height of the support posts 550. That is, the top end of the fixture 560 (i.e., the end remote from the body 510) is slightly farther than the top end of the support column 550 (i.e., the end remote from the body 510) or as far as the top end of the support column 550 relative to the body 510.

In some embodiments, the magnetic assembly 730 may include a plurality of magnets 731, and the plurality of magnets 731 are respectively disposed in the plurality of notches 540 of the first movable structure 500 and fixed on the main body 510.

In some embodiments, referring to fig. 2, 3, 9 and 10, the second movable structure 600 includes a base 620, an upper retaining wall 610 and a lower retaining wall 630. The substrate 620 is located in the limiting groove 520 and has a sensing window 621. The upper retaining wall 610 is located at the other side of the base 620 opposite to the groove bottom 522 of the limiting groove 520, and is connected to the base 620 along the periphery of the base 620. The lower retaining wall 630 is located at one side of the base plate 620 adjacent to the groove bottom 522 of the limiting groove 520, and is connected between the base plate 620 and the sensor carrier 400 along the periphery of the sensing window 621. In other words, the upper retaining wall 610 is distributed along the edge of the substrate 620 and protrudes from the upper surface of the substrate 620. The lower barrier wall 630 is distributed along the periphery of the sensing window 621 and protrudes from the lower surface of the substrate 620.

Here, the outer side wall of the upper retaining wall 610 has a recess 640. The notch 640 surrounds the substrate 620. The second coil assembly 710 is disposed within the notch 640 of the upper retaining wall 610. In some embodiments, the second coil assembly 710 may be embedded in the upper retaining wall 610. In some embodiments, the base 620, the upper wall 610, and the lower wall 630 may be integrally formed.

In some embodiments, the plurality of magnets 731 of the magnetic assembly 730 are embedded on the main body 510 of the first movable structure 500, and the second coil assembly 710 can be embedded on the upper retaining wall 610 of the second movable structure 600. Wherein the inner surface of the body 510 adjacent to the limit groove 520 exposes each of the magnets 731, and the surface of each of the magnets 731 adjacent to the limit groove 520 is substantially parallel to the inner surface of the body 510 adjacent to the limit groove 520. The outer side surface of the upper retaining wall 610 exposes the second coil set 710, and the surface of the second coil set 710 adjacent to the first movable structure 500 is substantially parallel to the outer side surface of the upper retaining wall 610. At this time, the size of the upper retaining wall 610 is smaller than the size of the limit groove 520 in a top view, so that a second gap exists between each magnet 731 of the magnetic assembly 730 and the second coil block 710.

As shown in fig. 2 to 4, in some embodiments, the image capturing apparatus 100 may further include an elastic element 800, and the elastic element 800 is fixed on the first movable structure 500 and the second movable structure 600. In some embodiments, the elastic member 800 includes an outer frame 810, an inner frame 820, and a connecting portion 830. The outer frame 810 is fixed to the first movable structure 500.

In the first movable structure 500, the groove wall of the limiting groove 520 (i.e., the main body 510 protrudes upward to form an upper retaining wall) is located above the outer frame plate 410. At this time, the plurality of magnets 731 of the magnetic assembly 730 are fixed in the slot wall (i.e., the upper blocking wall of the body 510 is protruded upward) corresponding to the positions of the plurality of first coils 721, respectively. The second coil assembly 710 is disposed between the plurality of magnets 731 and disposed in the retracted gap 640 of the second movable structure 600. Specifically, in some embodiments, the second coil set 710 may include one second coil 711. The second coil 711 is annular and surrounds the second movable structure 600.

In some embodiments, the plurality of first coils 721 corresponds one-to-one to the plurality of magnets 731. Each magnet 731 is located above the corresponding first coil 721, and there is a gap (i.e., a first gap) between each first coil 721 and the corresponding magnet 731. In some embodiments, the height of the support posts 550 is greater than the sum of the thicknesses of the outer frame plate 410 and the first coils 721 such that a first gap exists between each magnet 731 of the magnetic assembly 730 and the corresponding first coil 721.

In some embodiments, the image capturing apparatus 100 may further include a position sensor 740. The position sensor 740 is disposed on the sensor carrier 400 and is configured to sense a position of the first movable structure 500. In some embodiments, the position sensor 740 may be disposed in the first coil 721. More specifically, each position sensor 740 is disposed in one first coil 721. However, the number of position sensors 740 need not correspond to the number of first coils 721. However, when the image capturing apparatus 100 has a plurality of position sensors 740, such position sensors 740 may be disposed in different first coils 721. In some embodiments, the position sensors 740 may be disposed in adjacent first coils 721. For example, as shown in fig. 6, assuming that the number of the position sensors 740 is two, the two position sensors 740 are respectively located in two adjacent first coils 721, so that the first movable structure 500 can sense the motion in the direction parallel to the surface of the sensor carrier 400. Specifically, in some embodiments, the position sensor 740 is a Hall element that senses a change in magnetic field (the magnetic field of the magnetic assembly 730) caused by movement of the first movable structure 500 through the Hall effect.

In some embodiments, after the position sensor 740 senses the position of the first movable structure 500, the sensed signal can be output to the sensor wafer 920 or a processing wafer (not shown) disposed in the other way, and the sensor wafer 920 or the processing wafer disposed in the other way drives the corresponding coil set (the first coil set 720 and/or the second coil set 710) according to the signal output by the position sensor 740 (even if the current is applied) to generate the lorentz force, so as to move the first movable structure 500.

As shown in fig. 2 and 3, in some embodiments, the image capturing apparatus 100 may further include a metal sheet 222. The metal sheet 222 is located on the other side of the outer frame plate 410 opposite to the first coil assembly 720, and is configured for being attracted by the magnetic assembly 730. The first movable structure 500 and the sensor carrier 400 are preferably located close to the bottom plate 220 of the housing 200 by the magnetic attraction between the magnetic component 730 and the metal plate 222. In some embodiments, the metal plate 222 may be disposed at a location corresponding to each magnet 731 on the periphery of the cavity 221 of the bottom plate 220. In some embodiments, the number of metal sheets 222 corresponds to the number of magnets 731. In some embodiments, the metal sheet 222 may be secured to the base plate 220.

In summary, in the image capturing apparatus with anti-shake function provided in some embodiments of the present application, the movable structure (500, 600) drives the receiving plate 420 (and the sensor wafer 920 disposed thereon) to perform the triaxial displacement and/or rotation to compensate for shake, so that the lens assembly 300 is not required to be moved, and the lens assembly 300 can be fixed on the housing 200 without a gap therebetween, so that foreign objects such as external particles or moisture can be prevented from entering the image capturing apparatus 100 through the gap between the lens and the housing.

Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
