In some embodiments, the optical system 2-100 may generally include a top housing 2-110, a base housing 2-120, a second movable portion 2-130, a first coil 2-140, a first magnetic element 2-150, a first elastic element 2-160, a second elastic element 2-170, a first substrate 2-200, a circuit assembly 2-210, a ninth coil element 2-318, a tenth coil element 2-328, a first movable portion 2-400, a first optical element 2-500, a filter element 2-510, a second substrate 2-600, an elastic assembly 2-700, and a first driving assembly 2-800 arranged along a major axis 2-O. The optical systems 2-100 may be disposed on an electronic device, such as a mobile phone, a tablet computer, a notebook computer, etc., but not limited thereto.
The optical system 2-100 may be used to drive the second optical element 2-900, or may also be used to drive various optical elements (such as lenses, mirrors, prisms, beam splitters, apertures, liquid lenses, image sensors, camera modules, and ranging modules). It should be noted that the definition of optical elements herein is not limited to elements related to visible light, and elements related to invisible light (e.g., infrared light, ultraviolet light) and the like may also be included in the present disclosure.
In some embodiments, the top case 2-110, the bottom case 2-120, the second movable portion 2-130, the first coil 2-140, the first magnetic element 2-150, the first elastic element 2-160, and the second elastic element 2-170 may be collectively referred to as a first optical assembly 2-105 for driving the second optical element 2-900 to move in the direction X, Y, Z. In addition, the top case 2-110 and the bottom case 2-120 can be fixed on the first substrate 2-200, so the top case 2-110, the bottom case 2-120, and the first substrate 2-200 can be collectively referred to as a fixing portion 2-F. The first movable part 2-400 and the second movable part 2-130 are movable relative to the fixed part 2-F. In some embodiments, the second movable portion 2-130 can also move relative to the first movable portion 2-400.
It should be understood that the top case 2-110 and the base 2-120 are formed with a top case opening and a base opening, respectively, the top case opening having a center corresponding to the spindle 2-O (e.g., the spindle 2-O included in the fixing portion 2-F, wherein the top case 2-110 and the base 2-120 may be arranged along the spindle 2-O), the base opening corresponding to the first optical element 2-500, and the first optical element 2-500 may be disposed on the first substrate 2-200. Accordingly, the first optical element 2-500 may correspond to the second optical element 2-900, and may be arranged, for example, in the direction of the principal axis 2-O (e.g., Z-direction), such that the aforementioned second optical element 2-900 disposed in the second optical element 2-900 may be brought into focus with the first optical element 2-500 in the direction of the principal axis 2-O.
In some embodiments, the second movable portion 2-130 has a through hole, and the second optical element 2-900 can be fixed in the through hole to move together with the movement of the second movable portion 2-130, i.e. the second movable portion 2-130 can be used to carry the second optical element 2-900. In some embodiments, the first magnetic element 2-150 and the first coil 2-140 may be collectively referred to as a second driving element 2-D2 for driving the second movable portion 2-130 to move relative to the fixed portion 2-F.
The first magnetic elements 2-150 and the first coils 2-140 can be located on the fixed portion 2-F and the second movable portion 2-130, respectively, or the positions can be interchanged, depending on the design requirements. It should be understood that by the action between the first magnetic element 2-150 and the first coil 2-140, a magnetic force can be generated to force the second optical element 2-900 disposed on the second movable portion 2-130 to move relative to the fixed portion 2-F, such as Auto Focus (AF) or optical hand shock prevention (OIS) effect can be achieved. In some embodiments, the second driving element 2-D2 may also include a piezoelectric element, a shape memory alloy, or other driving element.
In the present embodiment, the second movable portion 2-130 and the second optical element 2-900 therein are movably (movably) disposed in the fixed portion 2-F. More specifically, the second movable portion 2-130 can be connected to the fixed portion 2-F through the first elastic element 2-160 and the second elastic element 2-170 made of metal material and suspended in the fixed portion 2-F. When the first coil 2-140 is energized, the first coil 2-140 will act on the magnetic field of the first magnetic element 2-150 and generate an electromagnetic driving force (electromagnetic force) to drive the second movable portion 2-130 and the second optical element 2-900 to move along the main axis 2-O direction relative to the fixed portion 2-F, so as to achieve the auto-focusing effect.
In some embodiments, a first sensing assembly 2-SE1 may also be provided in the optical system 2-100 for sensing the position of the second movable part 2-130 relative to the fixed part 2-F. The first sensing assembly 2-SE1 may include a first sensing element 2-SE11, a second sensing element 2-SE 12. The first sensing element 2-SE11 may be arranged on a stationary part 2-F (e.g. the first base plate 2-200 or the base plate 2-120) and the second sensing element 2-SE12 may be arranged on the second movable part 2-130, for example.
The first sensing element SE11 may include a Hall Effect Sensor (Hall Sensor), a magnetoresistive Effect Sensor (MR Sensor), a Giant magnetoresistive Effect Sensor (GMR Sensor), a Tunneling magnetoresistive Effect Sensor (TMR Sensor), or a flux Sensor (Fluxgate Sensor).
The second sensing element SE12 may comprise a magnetic element and the first sensing element 2-SE11 may sense the change of the magnetic field caused by the second sensing element 2-SE12 when the second movable part 2-130 is moved, so that the position of the second movable part 2-130 relative to the stationary part 2-F may be obtained. In some embodiments, similar other sensing elements may be provided for sensing the position of the first movable portion 2-400 relative to the fixed portion 2-F, for example between the first substrate 2-200 and the first movable portion 2-400.
For example, the sensing component can be used to sense the movement of the first moving part 2-400 or the second moving part 2-130 relative to the fixed part 2-F in different dimensions, such as the translation in the X direction (first dimension), the translation in the Y direction (second dimension), the translation in the Z direction (third dimension), the rotation with the Z axis as the rotation axis (fourth dimension), etc., but the disclosure is not limited thereto.
The first substrate 2-200 is, for example, a flexible printed circuit board (FPC), which can be fixed on the base 2-120 by adhesion. In the present embodiment, the first substrate 2-200 is electrically connected to other electronic components disposed inside or outside the optical system 2-100. For example, the first substrate 2-200 can transmit an electrical signal to the second driving device 2-D2, so as to control the movement of the second movable portion 2-130 in the X, Y or Z direction, thereby achieving the functions of Auto Focus (AF) or optical hand vibration prevention (OIS).
In some embodiments, the circuit components 2-210 are, for example, flexible printed circuit boards (FPCs), which can be fixed to the fixing portions 2-F by adhesion. In the embodiment, the circuit elements 2 to 210 are electrically connected to other electronic components or electronic devices disposed inside or outside the optical component driving mechanism 2 to 100. For example, the circuit component 2-210 can transmit the electrical signal of the electronic device to the first driving component 2-800, the first optical component 2-105, i.e. the first optical component 2-105 and the first driving component 2-800 are electrically connected to the electronic device through the circuit component 2-210, so as to control the movement of the first movable portion 2-400 in the X, Y or Z direction, thereby implementing the functions of Auto Focus (AF) or optical hand vibration prevention (OIS).
The ninth coil element 2-318 and the tenth coil element 2-328 may be disposed on the first movable part 2-400 and the fixed part 2-F, respectively. The ninth coil element 2-318, the first optical element 2-500 may be provided on the circuit assembly 2-210, and the ninth coil element 2-318 may surround the first optical element 2-500. The tenth coil element 2-328 may wirelessly transmit various signals to the ninth coil element 2-318 (described later).
The top case 2-110 of the fixed part 2-F has a polygonal structure, and the first movable part 2-400 may have a plate-shaped structure and may be perpendicular to the main shaft 2-O. The material of the first movable portion 2-400 may comprise plastic to avoid magnetic interference. The first optical element 2-500 and the filter element 2-510 may be arranged on (e.g. connected to) the first movable part 2-400, e.g. movable together with the first movable part 2-400 relative to the fixed part 2-F. The first optical element 2-500 may include a photoelectric converter, such as a photosensitive element, for corresponding to and sensing the light passing through the second optical element 2-900, converting the light into an electrical signal, and providing the electrical signal to the electronic device. In some embodiments, the first movable portion 2-400 is movable relative to the fixed portion 2-F. Therefore, the first optical element 2-500 disposed on the first movable portion 2-400 is also moved together by the first movable portion 2-400, thereby achieving, for example, an optical hand-shake prevention (OIS). The first optical element 2-500 is configured to receive an optical signal and output an image signal.
In some embodiments, a first communication element 2-341 and a second communication element 2-342 may be provided in the optical system 2-100. The first communication element 2-341 may be fixed to the first movable part 2-400 and the second communication element 2-342 may be fixed to the fixed part 2-F, and the first communication element 2-341 and the second communication element 2-342 may be collectively referred to as a first communication component 2-340A. The image signal is output to an external circuit for communication via a first signal (wireless electromagnetic wave) transmitted by the first communication means 2-340A. For example, the optical system 2-100 may be disposed on an electronic device (e.g., a mobile phone, a tablet computer, a notebook computer, etc.), and the external circuit is an external circuit of the electronic device.
In some embodiments, the first communication element 2-341 and the second communication element 2-342 have a spacing greater than zero, i.e., the first communication element 2-341 and the second communication element 2-342 are not connected via wires and are thus electrically independent. For example, the first signal may be transmitted wirelessly from the first communication element 2-341 to the second communication element 2-342 or from the second communication element 2-342 to the first communication element 2-341. The second communication elements 2-342 can be electrically connected to the external circuit of the electronic device. The first communication elements 2-341 and the second communication elements 2-342 may comprise, for example, a first integrated circuit element and a second integrated circuit element, respectively, for transmitting signals. The first communication component 2-340A may comprise, for example, Bluetooth (Bluetooth), Wireless Local Area Network (WLAN), Wireless Wide Area Network (WWAN), etc., depending on design requirements.
The filter elements 2-510 may only allow light of a specific wavelength to pass through and filter out other light having unwanted wavelengths, i.e. may filter electromagnetic waves of a specific wavelength. For example, the filter elements 2-510 can filter infrared light and allow visible light to pass through, but not limited thereto. The filter element 2-510 may correspond to the first optical element 2-500. Thus, the light sensed by the first optical element 2-500 can be made closer to the naked eye.
The second base plate 2-600 may be disposed on the first movable portion 2-400, the elastic member 2-700 may be configured to movably connect the second base plate 2-600 with the fixed portion 2-F (e.g., the base 2-120), and the first driving member 2-800 may be configured to drive the first movable portion 2-400 to move with respect to the fixed portion 2-F or with respect to the second movable portion 2-130.
In some embodiments, the first driving assembly 2-800 may be configured to drive the first movable portion 2-400 to move relative to the fixed portion 2-F. In some embodiments, the material of the drive element of the first drive assembly 2-800 may comprise Shape Memory Alloy (SMA) and have an elongated Shape and extend in one direction. The shape memory alloy is an alloy material which can completely eliminate the deformation of the shape memory alloy at a lower temperature after being heated and recover the original shape of the shape memory alloy before the deformation. For example, after a finite amount of plastic deformation of the shape memory alloy below the transformation temperature, the shape memory alloy can be heated to return to its original shape prior to the deformation.
The elastic member 2-700 may be movably coupled to the second base plate 2-600 by the first driving member 2-800. When the driving element in the first driving assembly 2-800 is deformed, the second substrate 2-600 and the elastic assembly 2-700 are driven to move relatively, so that the first movable portion 2-400 is allowed to move relative to the fixed portion 2-F, and the first optical element 2-500 arranged on the first movable portion 2-400 is moved together, thereby achieving the optical anti-shake effect.
Fig. 5A is a schematic diagram of some elements of optical system 2-100A. The elements of the optical system 2-100A may be substantially similar to the optical system 2-100, and only some of the elements are shown in FIG. 5A. The top housing 2-110 of the retainer portion 2-F may include a first side 2-S1, a second side 2-S2, a third side 2-S3, and a fourth side 2-S4, wherein the second side 2-S2 is not parallel to the first side 2-S1, the third side 2-S3 is parallel to the first side 2-S1, and the fourth side 2-S4 is parallel to the second side 2-S2, as viewed along the direction of the major axis 2-O (Z-direction). In addition, the top case 2-110 further comprises a first corner 2-C1, a second corner 2-C2, a third corner 2-C3, and a fourth corner 2-C4. First corner 2-C1 is located between fourth side 2-S4 and first side 2-S1, second corner 2-C2 is located between first side 2-S1 and second side 2-S2, third corner 2-C3 is located between second side 2-S2 and third side 2-S3, and fourth corner 2-C4 is located between third side 2-S3 and fourth side 2-S4.
The ninth coil element 2-318, the tenth coil element 2-328 may be arranged to surround the first optical element 2-500, seen along the main axis 2-O, but not to overlap the first optical element 2-500, in order to avoid magnetic interference. The spindle 2-O may pass through the ninth coil element 2-318 and the tenth coil element 2-328. Further, the ninth coil element 2-318 may overlap the tenth coil element 2-328 to provide a signal from the tenth coil element 2-328 to the ninth coil element 2-318 by way of electromagnetic induction.
However, the present disclosure is not so limited. For example, FIG. 5B is a schematic diagram of some elements of optical system 2-100B. The elements of the optical system 2-100B may be substantially similar to the optical system 2-100, and only some of the elements are shown in FIG. 5B. In fig. 5B, the optical system 2-100B may further include a first coil element 2-310, a second coil element 2-320, a third coil element 2-312, a fourth coil element 2-322, a fifth coil element 2-314, a sixth coil element 2-324, a seventh coil element 2-316, and an eighth coil element 2-326 in addition to the ninth coil element 2-318 and the tenth coil element 2-328. The first coil element 2-310 corresponds to the second coil element 2-320, the third coil element 2-312 corresponds to the fourth coil element 2-322, the fifth coil element 2-314 corresponds to the sixth coil element 2-324, the seventh coil element 2-316 corresponds to the eighth coil element 2-326, and the ninth coil element 2-318 corresponds to the tenth coil element 2-328.
For example, the first coil element 2-310 and the second coil element 2-320 at least partially overlap, the third coil element 2-312 and the fourth coil element 2-322 at least partially overlap, the fifth coil element 2-314 and the sixth coil element 2-324 at least partially overlap, the seventh coil element 2-316 and the eighth coil element 2-326 at least partially overlap, and the ninth coil element 2-318 and the tenth coil element 2-328 at least partially overlap, as viewed along the winding axis of each coil element.
In some embodiments, the first coil element 2-310, the third coil element 2-312, the fifth coil element 2-314, the seventh coil element 2-316, and the ninth coil element 2-318 may be collectively referred to as a first coil assembly 2-W1 (or third communication element 2-343), and the second coil element 2-320, the fourth coil element 2-322, the sixth coil element 2-324, the eighth coil element 2-326, and the tenth coil element 2-328 may be collectively referred to as a second coil assembly 2-W2 (or fourth communication element 2-344). The third communication element 2-343, the fourth communication element 2-344 may be collectively referred to as the second communication component 2-340B. The first communication component 2-340A and the second communication component 2-340B may form a communication module 2-340 for connecting to external circuits.
Furthermore, the first optical element 2-500 is at least partly non-overlapping with the first coil assembly 2-W1 or the second coil assembly 2-W2, viewed in the direction of the main axis 2-O (Z-direction), in order to avoid magnetic interference. And the first coil assembly 2-W1 at least partially overlaps the second coil assembly 2-W2 to transmit signals by way of electromagnetic induction.
Viewed in the direction of the main axis 2-O, the first coil element 2-310, the second coil element 2-320, the third coil element 2-312, the fourth coil element 2-322 are located at the first side 2-S1, the third coil element 2-312, the fourth coil element 2-322, the fifth coil element 2-314, the sixth coil element 2-324 are located at the second side 2-S2, the fifth coil element 2-314, the sixth coil element 2-324, the seventh coil element 2-316, the eighth coil element 2-326 are located at the third side 2-S3, and the first coil element 2-310, the second coil element 2-320, the seventh coil element 2-316, the eighth coil element 2-326 are located at the fourth side 2-S4. Further, the first coil element 2-310, the second coil element 2-320 are located at a first corner 2-C1, the third coil element 2-312, the fourth coil element 2-322 are located at a second corner 2-C2, the fifth coil element 2-314, the sixth coil element 2-324 are located at a third corner 2-C3, the seventh coil element 2-316, the eighth coil element 2-326 are located at a fourth corner 2-C4. For example, the first coil element 2-310, the second coil element 2-320 and the third coil element 2-312, the fourth coil element 2-322, the fifth coil element 2-314, the sixth coil element 2-324, the seventh coil element 2-316, the eighth coil element 2-326 do not overlap (i.e., the first coil assembly 2-W1 and the second coil assembly 2-W2 do not at least partially overlap). This prevents magnetic interference from occurring between the coils.
The second coil assembly 2-W2 (the fourth pass cell 2-344) can be used to transmit a power signal to the first coil assembly 2-W1 (the third pass cell 2-343) in a wireless manner, i.e. the power signal transmitted by the external circuit via the second communication assembly 2-340B is input to the first optical assembly 2-105, so as to achieve the effect of wireless charging. For example, when an alternating current signal is provided to the second coil element 2-W2, the first coil element 2-W1 generates an induced electromotive force (induced electromotive force) accordingly, so that the power signal can be wirelessly transmitted to the first coil element 2-W1.
Alternatively, an additional magnetic element, such as a magnet or a ferromagnetic material (e.g., iron, cobalt, nickel, etc.), may be disposed on the first movable portion 2-400, and when a dc signal is provided to the second coil assembly 2-W2, the second coil assembly 2-W2 may act as an electromagnet and generate an electromagnetic driving force with the magnetic element on the first movable portion 2-400 to drive the first movable portion 2-400 to move relative to the fixed portion 2-F. In this case, the thrust force required to be generated by the first driving unit 2-800 can be reduced, and the first driving unit 2-800 having a smaller size can be used, or the first driving unit 2-800 can be omitted to achieve miniaturization.
In addition, a first supporting member 2-360 and a second supporting member 2-370 may be further disposed between the first movable portion 2-400 and the fixed portion 2-F (e.g., the first base plate 2-200). The first support assembly 2-360 may include a spherical first support element 2-362, a second support element 2-364, and a third support element 2-366. Second support assembly 2-370 may include a fourth spherical support element 2-372, a fifth spherical support element 2-374, and a sixth spherical support element 2-376. The first supporting member 2-362, the second supporting member 2-364, the third supporting member 2-366, the fourth supporting member 2-372, the fifth supporting member 2-374 and the sixth supporting member 2-376 may be located at a side or a corner of the first movable part 2-400 or the top case 2-110 to restrict the position of the first movable part 2-400 with respect to the fixed part 2-F.
In some embodiments, the first support element 2-362, the second support element 2-364, and the third support element 2-366 may have substantially the same diameter, the fourth support element 2-372, the fifth support element 2-374, and the sixth support element 2-376 may also have substantially the same diameter, and the diameter of the first support element 2-362, the second support element 2-364, and the third support element 2-366 may be different from the diameter of the fourth support element 2-372, the fifth support element 2-374, and the sixth support element 2-376.
For example, the diameters of the first support element 2-362, the second support element 2-364, and the third support element 2-366 are larger than the diameters of the fourth support element 2-372, the fifth support element 2-374, and the sixth support element 2-376. Thus, in the rest state, the first supporting member 2-362, the second supporting member 2-364, and the third supporting member 2-366 may directly contact the first movable portion 2-400 and the fixed portion 2-F, while the fourth supporting member 2-372, the fifth supporting member 2-374, and the sixth supporting member 2-376 directly contact only the fixed portion 2-F and are spaced apart from the first movable portion 2-400. That is, the first movable portion 2-400 may be connected to the fixed portion 2-F through the first supporting member 2-360.
When viewed in the direction of the main axis 2-O, as shown by the dotted lines in FIG. 5B, the first support element 2-362, the second support element 2-364, and the third support element 2-366 form a first triangular structure 2-368, and the first triangular structure 2-368 does not overlap with the fourth support element 2-372, the fifth support element 2-374, and the sixth support element 2-376. In addition, the fourth support element 2-372, the fifth support element 2-374 and the sixth support element 2-376 form a second triangular structure 2-378, and the second triangular structure 2-378 does not overlap with the first support element 2-362, the second support element 2-364 and the third support element 2-366. When the first movable portion 2-400 is impacted, the rotation axis formed by the connection line of any two of the first support element 2-362, the second support element 2-364, and the third support element 2-366 may rotate. For example, when the first movable portion 2-400 can rotate through the rotation axis formed by the connection line of the first supporting element 2-362 and the second supporting element 2-364. In this state, by the aforementioned positional relationship (the first triangular structure 2-368 is not overlapped with the fifth support member 2-374), the fifth support member 2-374 can serve as a stopper structure to limit the maximum rotatable range of the first movable portion 2-400, thereby preventing the first movable portion 2-400 from colliding with other members.
In the following embodiments, the first supporting elements 2-360 and the second supporting elements 2-370 in the present embodiment may also be disposed, and the first supporting elements 2-360 and the second supporting elements 2-370 are omitted in the following description for brevity.
Fig. 5C is a schematic diagram of some elements of the optical system 2-100C. The elements of the optical system 2-100C may be substantially similar to the optical system 2-100 described above, and only some of the elements are shown in FIG. 5C. In fig. 5C, the aforementioned ninth coil element 2-318 and tenth coil element 2-328 may be omitted. Further, the first coil element 2-310, the third coil element 2-312, the fifth coil element 2-314, the seventh coil element 2-316 may have a size different from that of the second coil element 2-320, the fourth coil element 2-322, the sixth coil element 2-324, the eighth coil element 2-326.
For example, the dimensions of the first coil element 2-310, the third coil element 2-312, the fifth coil element 2-314, the seventh coil element 2-316 may be smaller than the dimensions of the second coil element 2-320, the fourth coil element 2-322, the sixth coil element 2-324, the eighth coil element 2-326, i.e. the first coil component 2-W1 does not completely overlap the second coil component 2-W2, but is partially exposed to the second coil component 2-W2, as seen in the direction of the main axis 2-O. Thus, the size of each coil of the first movable section 2 to 400 can be reduced, and the size can be reduced.
Although the coil elements in the foregoing embodiments are disposed at the corners of the top cases 2 to 110, the present disclosure is not limited thereto. For example, FIG. 5D is a schematic diagram of some elements of optical system 2-100D. The elements of optical systems 2-100D may be substantially similar to optical systems 2-100 described above, with only some of the elements shown in FIG. 5D.
In fig. 5D, there are further included eleventh and twelfth coil elements 2-311 and 2-321 disposed at the first side 2-S1, and thirteenth and fourteenth coil elements 1-315 and 1-325 disposed at the third side 2-S3. The eleventh coil element 2-311, the thirteenth coil element 1-315 may be part of a first coil assembly 2-W1, and the twelfth coil element 2-321, the fourteenth coil element 1-325 may be part of a second coil assembly 2-W2. The eleventh and thirteenth coil elements 2-311 and 1-315 of the first coil block 2-W1 may be provided on the first movable part 2-400, and the twelfth and fourteenth coil elements 2-321 and 1-325 of the second coil block 2-W2 may be provided on the fixed part 2-F.
By providing additional eleventh, twelfth, thirteenth and fourteenth coil elements 2-311, 2-321, 1-315 and 1-325 at the side edges, the maximum power of the signal transmitted to the first coil assembly 2-W1 by the second coil assembly 2-W2 can be increased to enhance the transmission effect. In addition, the coil elements are arranged at the side edges, and the space of the side edges can be further utilized, so that the miniaturization is realized.
Fig. 6A, 6B are schematic side views of the optical systems 2-100D from different directions, with only some of the elements shown for clarity. As shown in fig. 6A, 6B, in the Z direction, the fifth coil element 2-314 may be aligned with the sixth coil element 2-324, the seventh coil element 2-316 may be aligned with the eighth coil element 2-326, and the thirteenth coil element 1-315 may be aligned with the fourteenth coil element 1-325.
Fig. 5E is a schematic diagram of some elements of optical system 2-100E. The elements of optical systems 2-100E may be substantially similar to optical systems 2-100 described above, with only some of the elements shown in FIG. 5E. In fig. 5E, the distance between the first coil element 2-310, the eleventh coil element 2-311, and the third coil element 2-312 and the distance between the second coil element 2-320, the twelfth coil element 2-321, and the fourth coil element 2-322 may be different in the X direction.
For example, in the X-direction (first direction), the distance 2-L1 between the center 2-310C of the first coil element 2-310 and the center 2-312C of the third coil element 2-312 is different from the distance 2-L2 between the center 2-320C of the second coil element 2-320 and the center 2-322C of the fourth coil element 2-322, e.g. the distance 2-L1 may be smaller than the distance 2-L2, while the eleventh coil element 2-311 may overlap the twelfth coil element 2-321. The fifth coil element 2-314, the sixth coil element 2-324, the seventh coil element 2-316, the eighth coil element 2-326, the thirteenth coil element 1-315, and the fourteenth coil element 1-325 may have similar positional relationships, and will not be described herein again.
Further, in the Y direction (second direction), the first coil element 2-310, the eleventh coil element 2-311, the third coil element 2-312, the second coil element 2-320, the twelfth coil element 2-321, and the fourth coil element 2-322 may be aligned with the seventh coil element 2-316, the eighth coil element 2-326, the thirteenth coil element 1-315, the fourteenth coil element 1-325, the fifth coil element 2-314, and the sixth coil element 2-324, respectively, to provide more uniform charging power.
FIG. 6C is a side view schematic of optical systems 2-100E, with only some of the elements shown for clarity. As shown in fig. 6C, in the Z-direction, the thirteenth coil element 2-1-315 may be aligned with the fourteenth coil element 2-1-325, while the fifth coil element 2-314 may be misaligned with the sixth coil element 2-324 and the seventh coil element 2-316 may be misaligned with the eighth coil element 2-326. In the X-direction (first direction) the distance 2-L1 between the center 2-310C of the first coil element 2-310 and the center 2-312C of the third coil element 2-312 is different from the distance 2-L2 between the center 2-320C of the second coil element 2-320 and the center 2-322C of the fourth coil element 2-322, e.g. the distance 2-L1 may be smaller than the distance 2-L2.
Fig. 5F is a schematic diagram of some elements of optical system 2-100F. The elements of optical systems 2-100F may be substantially similar to optical systems 2-100 described above, with only some of the elements shown in FIG. 5F. In fig. 5F, the distance 2-L3 between the center 2-312C of the third coil element 2-312 and the center 2-314C of the fifth coil element 2-314 and the distance 2-L4 between the center 2-322C of the fourth coil element 2-322 and the center 2-324C of the sixth coil element 2-324 in the Y-direction are different, e.g., the distance 2-L3 may be smaller than the distance 2-L4. The first coil elements 2-310, the second coil elements 2-320, the seventh coil elements 2-316, and the eighth coil elements 2-326 may have similar positional relationships, and are not described herein again.
In some embodiments, additional magnetism isolating components may be provided in the optical system, for example on the first movable portion 2-400. For example, FIG. 7A is a schematic diagram of some elements of optical system 2-100G. The elements of the optical system 2-100G may be substantially similar to the optical system 2-100 described above, and only some of the elements are shown in FIG. 7A. The first movable portion 2-400 of the optical system 2-100G may have a first magnetism isolating member 2-332 thereon. The first coil component 2-W1 may be disposed on the first side 2-400A of the first movable part 2-400, and the second coil component 2-W2 may be disposed on the third side 2-200A of the first base plate 2-200 with the first side 2-400A facing in the same direction as the third side 2-200A. The first magnetic isolating element 2-332 is at least partially arranged between the first optical component 2-105 (e.g. the first optical element 2-500) and the first coil component 2-W1 or the second coil component 2-W2, and the first magnetic isolating element 2-332 and the first optical component 2-105 (e.g. the first optical element 2-500) at least partially overlap in the direction of the main axis 2-O (Z-direction). Further, the first magnetic shield element 2-332, the first optical element 2-500, and the first coil block 2-W1 are at least partially overlapped in the X direction or the Y direction.
In addition, the first magnetic isolation elements 2-332 may be made of a magnetic material (e.g., metal). By the overlapping position relationship, the electromagnetic signal generated between the first coil assembly 2-W1 and the second coil assembly 2-W2 can be prevented from interfering with the first optical element 2-500, so that the first optical element 2-500 can obtain a more accurate signal. In addition, the first magnetic isolating element 2-332 can be partially embedded in the first movable part 2-400 and partially exposed out of the first movable part 2-400, so that the required volume is reduced and the miniaturization is realized.
Fig. 7B is a schematic diagram of some elements of the optical system 2-100H. The elements of optical systems 2-100H may be substantially similar to optical systems 2-100 described above, and only some of the elements are shown in FIG. 7B. The first movable part 2-400 of the optical system 2-100H may have a second magnetic shield element 2-334, for example, on a different side of the first movable part 2-400 than the first coil element 2-310, the third coil element 2-312. The first coil component 2-W1 may be disposed on the first side 2-400A of the first movable part 2-400, and the second coil component 2-W2 may be disposed on the third side 2-200A of the first base plate 2-200 with the first side 2-400A facing in the same direction as the third side 2-200A.
The second magnetic isolating elements 2-334 may be of similar material as the first magnetic isolating elements 2-332 described previously. The second magnetically isolating element 2-334 is at least partly arranged between the first optical component 2-105 (e.g. the first optical element 2-500) and the first coil component 2-W1 or the second coil component 2-W2, and the second magnetically isolating element 2-334 at least partly overlaps the first optical component 2-105 (e.g. the first optical element 2-500) in the direction of the main axis 2-O (Z-direction). The second flux barrier 2-334 is at least partly arranged between the first coil block 2-W1 and the second coil block 2-W2 in the direction of the main axis 2-O. By the overlapping position relationship, the electromagnetic signal generated between the first coil assembly 2-W1 and the second coil assembly 2-W2 can be prevented from interfering with the first optical element 2-500, so that the first optical element 2-500 can obtain a more accurate signal.
Fig. 7C is a schematic diagram of some elements of optical system 2-100I. The elements of the optical system 2-100I may be substantially similar to the optical system 2-100 described above, and only some of the elements are shown in FIG. 7C. The optical system 2-100I may have a third magnetic shielding element 2-336 on the first movable portion 2-400, for example, partially embedded in the first movable portion 2-400 and partially exposed from the first movable portion 2-400. The third magnetic isolating element 2-336 may be of a similar material as the first magnetic isolating element 2-332 described above. The third magnetic isolating element 2-336 is at least partly arranged between the first optical component 2-105, e.g. the first optical element 2-500, and the first coil component 2-W1 or the second coil component 2-W2.
Although the first coil units 2-W1 are all disposed on the side of the first movable part 2-400 facing away from the second coil unit 2-W2 in the foregoing embodiments, the disclosure is not limited thereto. For example, in fig. 7C, the first coil element 2-W1 may be disposed on the second side 2-400B of the first movable portion 2-400, and the second coil element 2-W2 may be disposed on the third side 2-200A of the first substrate 2-200, with the second side 2-400B facing toward the third side 2-200A, i.e., facing in the opposite direction.
Further, the first coil block 2-W1, the second coil block 2-W2 and the first optical element 2-500 are disposed on the opposite side of the third magnetism isolating element 2-336. By the overlapping position relationship, the electromagnetic signal generated between the first coil assembly 2-W1 and the second coil assembly 2-W2 can be prevented from interfering with the first optical element 2-500, so that the first optical element 2-500 can obtain a more accurate signal.
The first, second and third magnetism isolating elements 2-332, 2-334 and 2-336 may be collectively referred to as a magnetism isolating assembly, and although the foregoing embodiments show embodiments in which each optical system has a single magnetism isolating element, it should be understood that the first, second and third magnetism isolating elements 2-332, 2-334 and 2-336 may exist at the same time, for example, the first, second and third magnetism isolating elements 2-332, 2-334 and 2-336 may be provided in the same optical system at the same time to achieve a further magnetism isolating effect.
Furthermore, as shown in fig. 7C, an additional energy storage element 2-350 may also be provided on the first movable part 2-400 of the optical system 2-100I, and fig. 7C also shows a first communication element 2-341 and a second communication element 2-342. It should be noted that the first communication elements 2-341, the second communication elements 2-342, and the energy storage elements 2-350 are also applicable to the aforementioned embodiments, and are only shown in fig. 7C for simplicity. The energy storage element 2-350 may be, for example, a battery, and may be electrically connected to the third T-cell element 2-343 (the first coil assembly 2-W1) to power the first coil assembly 2-W1 when the current provided by the second coil assembly 2-W2 to the first coil assembly 2-W1 is insufficient.
In addition, the first communication component 2-340A may further include a blocking element 2-345, such as a copper foil, disposed on the top case 2-110 of the fixing portion 2-F, and the blocking element 2-345 and the first communication element 2-341 are disposed on different sides of the second communication element 2-342, so as to prevent external signals from interfering with the second communication element 2-342, and allow the second communication element 2-342 to receive only signals transmitted by the first communication element 2-341, thereby improving the quality of signal transmission.
Fig. 8A is a diagram showing the relationship between the optical system 2-100 and the external circuit 2-EXT. The external circuit 2-EXT may be adapted to provide the input signal 2-IN to the optical system 2-100 and the first optical element 2-500 of the first optical component 2-105 may receive an optical signal 2-OS from the outside and convert the optical signal 2-OS into an image signal 2-IS to be provided to the external circuit 2-EXT. In particular, the image signal IS may be input to the first communication assembly 2-340A and the image signal 2-IS converted into a first signal 2-SI1 at the first communication element 2-341 of the first communication assembly 2-340A. The first signal 2-SI1 is then transmitted wirelessly from the first communication element 2-341 of the first communication component 2-340A to the second communication element 2-342 and out to the external circuit 2-EXT for communication. Thus, the wiring for connecting the elements can be omitted, and the miniaturization can be achieved.
Fig. 8B is a detailed schematic diagram of some of the elements of fig. 8A. Specifically, when the second communication module 2-340B of the optical system 2-100 receives the input signal 2-IN inputted from the external circuit 2-EXT, the input signal 2-IN may be converted at the fourth communication element 2-344 of the second communication module 2-340B into the second signal 2-SI2 and the power signal 2-PW0, and the second signal 2-SI2 and the power signal 2-PW0 may be provided wirelessly from the fourth communication element 2-344 to the third communication element 2-343, the second signal 2-SI2 and the power signal 2-PW0 are then converted into a third signal 2-SI3 and an induced power signal 2-IPW, respectively, by the third communication element 2-343, and finally the third signal 2-SI3 and the induced power signal 2-IPW are input to the first optical component 2-105. Thus, the wiring for connecting the elements can be omitted, and the miniaturization can be achieved.
It should be noted that the power signal 2-PW0 and the second signal 2-SI2 have different frequencies and different powers, so the power signal 2-PW0 and the second signal 2-SI2 can be used to transmit different information respectively. For example, the power of the power supply signal 2-PW0 may be greater than the power of the second signal 2-SI2, so that energy may be transferred from the external circuit 2-EXT to the first optical component 2-105 primarily through the power supply signal 2-PW0 for wireless charging functions. In addition, the second signals 2-SI2 may be used to convey signals for controlling the first optical elements 2-105, thereby eliminating the need for additional circuitry to control the first optical elements 2-105.
It should be noted that when the power supply signal 2-PW0 is supplied to the second coil elements 2-320, fourth coil elements 2-322, sixth coil elements 2-324, eighth coil elements 2-326, and tenth coil elements 2-328 of the aforementioned fourth communication elements 2-344, the power supply signal 2-PW0 may be divided into a first power supply signal 2-PW1, a second power supply signal 2-PW2, a third power supply signal 2-PW3, a fourth power supply signal 2-PW4, and a fifth power supply signal 2-PW5, which are supplied to the second coil elements 2-320, fourth coil elements 2-322, sixth coil elements 2-324, eighth coil elements 2-326, and tenth coil elements 2-328, respectively. Then, the second coil element 2-320, the fourth coil element 2-322, the sixth coil element 2-324, the eighth coil element 2-326, and the tenth coil element 2-328 can supply the first power signal 2-PW1, the second power signal 2-PW2, the third power signal 2-PW3, the fourth power signal 2-PW4, and the fifth power signal 2-PW5 to the first coil element 2-310, the third coil element 2-312, the fifth coil element 2-314, the seventh coil element 2-316, and the ninth coil element 2-318, respectively, in a wireless manner (e.g., electromagnetic induction).
It should be noted that under normal conditions (e.g. the first movable part 2-400 does not move beyond the limit with respect to the fixed part 2-F), the sum of the first power signal 2-PW1, the second power signal 2-PW2, the third power signal 2-PW3, the fourth power signal 2-PW4, and the fifth power signal 2-PW5 will generate an induced power signal 2-IPW that is greater than the energy 2-EN (not shown) required for the operation of the first optical element 2-105. In other words, (2-IPW) > (2-EN). Thereby, it is ensured that the first optical component 2-105 has sufficient energy to operate.
Under the normal condition, the excess energy in the inductive power signal 2-IPW can be transmitted to the energy storage elements 2-350 for storage. For example, the induced power signal 2-IPW may be converted into a sixth power signal 2-PW6 and a seventh power signal 2-PW7 by the first control unit 2-382 and the second control unit 2-384 of the optical system 2-100, wherein the sixth power signal 2-PW6 may be provided to the first optical component 2-105 and the seventh power signal 2-PW7 may be provided to the energy storage element 2-350 by the first control unit 2-382 and the second control unit 2-384.
However, if the first movable part 2-400 is impacted to move beyond the limit with respect to the fixed part 2-F (during an abnormal condition), the coil elements in the third pass cell 2-343 may not be aligned with the coil elements in the fourth pass cell 2-344, so that the sum of the first power signal 2-PW1, the second power signal 2-PW2, the third power signal 2-PW3, the fourth power signal 2-PW4, and the fifth power signal 2-PW5 may be less than the energy 2-EN required for the operation of the first optical element 2-105. In this case, the first control unit 2-382 can be supplied with a standby signal 2-BA via the energy storage element 2-350, the standby signal 2-BA being, for example, a standby current to compensate. In this situation, the sum of the induced power signal 2-IPW and the standby signal 2-BA is greater than the energy 2-EN required for the operation of the first optical component 2-105, i.e., (2-IPW) + (2-BA) > (2-EN), thereby ensuring that the first optical component 2-105 can operate normally.
Furthermore, the third communication element 2-343 may comprise an activation coil element 2-346, and the fourth communication element 2-344 may provide the second signal 2-SI2 wirelessly to the activation coil element 2-346, which activation coil element 2-346 in turn converts the second signal 2-SI2 into a third signal 2-SI3 to be provided to the first control unit 2-382. The activation coil element 2-346 may be used to inform the first control unit 2-382 to activate the first optical component 2-105 when the first optical component 2-105 is turned off.
Fig. 8C to 8E are schematic views showing the positional relationship between the first movable portion 2-400 and the top case 2-110 of the fixed portion 2-F in the optical system. In fig. 8C, the first coil element 2-310, the third coil element 2-312, the fifth coil element 2-314, and the seventh coil element 2-316 are not aligned with the second coil element 2-320, the fourth coil element 2-322, the sixth coil element 2-324, and the eighth coil element 2-326, and the ninth coil element 2-318 is aligned with the tenth coil element 2-328 in the Z direction, when the first movable portion 2-400 is at a predetermined position with respect to the fixed portion 2-F. The larger the area of overlap between the coil elements, the higher the strength of the transmitted power signal. In other words, the fifth power signal 2-PW5 is greater than the first power signal 2-PW1 and the third power signal 2-PW3 at this time.
In fig. 8D, the first movable part 2-400 is moved in the-Y direction relative to the top shell 2-100, so that the first movable part 2-400 is in a first extreme position relative to the fixed part 2-F. As compared with the condition of fig. 8C, the area where the first coil elements 2-310 and the third coil elements 2-312 overlap with the second coil elements 2-320 and the fourth coil elements 2-322 is increased, the areas of the fifth coil element 2-314, the seventh coil element 2-316, the ninth coil element 2-318, the sixth coil element 2-324, the eighth coil element 2-326, and the tenth coil element 2-328 overlapping are decreased, so that the first power signal 2-PW1 is greater than the third power signal 2-PW3 and the fifth power signal 2-PW5, and since the area of overlap of the fifth coil element 2-314 with the sixth coil element 2-324 is smaller than the area of overlap of the ninth coil element 2-318 with the tenth coil element 2-328, the third power signal 2-PW3 is smaller than the fifth power signal 2-PW5 at this time.
Conversely, as shown in FIG. 8E, the first movable section 2-400 is moved in the Y direction relative to the top housing 2-100 such that the first movable section 2-400 is in a second limit position relative to the fixed section 2-F. The first limit position is different from the second limit position, and the preset position is between the first limit position and the second limit position. Compared to the situation of fig. 8C, the area where the fifth coil element 2-314, the seventh coil element 2-316 and the sixth coil element 2-324, the eighth coil element 2-326 overlap is increased, the areas of the first coil element 2-310, the third coil element 2-312, the ninth coil element 2-318, the second coil element 2-320, the fourth coil element 2-322, and the tenth coil element 2-328 overlapping are reduced, so that the third power signal 2-PW3 is larger than the first power signal 2-PW1 and the fifth power signal 2-PW5, and since the area of overlap of the first coil element 2-310 and the second coil element 2-320 is smaller than the area of overlap of the ninth coil element 2-318 and the tenth coil element 2-328, the first power signal 2-PW1 is smaller than the fifth power signal 2-PW5 at this time.
In addition, the fourth communication element 2-344 can transmit power signals to the third communication element 2-343 by means of alternating current, and can also pass direct current through some coil elements in the fourth communication element 2-344 to simultaneously serve as electromagnets. The coil element passing through the direct current can generate an electromagnetic driving force with other magnetic elements on the first movable part 2-400 to drive the first movable part 2-400 to move relative to the fixed part 2-F. Thus, the volume required for the first driving assembly 2-800 can be reduced, or the first driving assembly 2-800 can be omitted for miniaturization.
For example, when the first movable portion 2-400 is located at a predetermined position with respect to the fixed portion 2-F, as shown in fig. 8C, a direct current is passed through the second coil element 2-320, the fourth coil element 2-322, the sixth coil element 2-324, and the eighth coil element 2-326, and an alternating current is passed through the tenth coil element 2-328 to transmit a power signal through the ninth coil element 2-328 and the tenth coil element 2-328 having the largest overlapping area, and the other coil elements having the smaller overlapping area may be used to drive the first movable portion 2-400.
Similarly, when the first movable part 2-400 is located at the first limit position with respect to the fixed part 2-F, as shown in fig. 8D, alternating current is passed through the second coil element 2-320 and the fourth coil element 2-322, and direct current is passed through the sixth coil element 2-324, the eighth coil element 2-326 and the tenth coil element 2-328 to transmit a power supply signal by overlapping the first coil element 2-310, the second coil element 2-320, and the third coil element 2-312 and the fourth coil element 2-322 having the largest area, and the other coil elements having smaller overlapping areas may be used to drive the first movable part 2-400.
Similarly, as shown in fig. 8E, when the first movable part 2-400 is located at the second limit position with respect to the fixed part 2-F, ac power is passed through the sixth coil element 2-324 and the eighth coil element 2-326 and dc power is passed through the second coil element 2-320, the fourth coil element 2-322 and the tenth coil element 2-328 to transmit the power supply signal by overlapping the fifth coil element 2-314, the sixth coil element 2-324, the seventh coil element 2-316 and the eighth coil element 2-326 having the largest area, and the other coil elements having a smaller overlapping area may be used to drive the first movable part 2-400.
FIG. 9 is a flowchart of a process 2-PR during operation of the optical system 2-100. The process 2-PR starts with step 2-ST1, in which the energy required for the operation of the first optical element 2-105 is determined by the second control unit 2-384. The processing program 2-PR then proceeds to step 2-ST2, where the first control unit 2-382 is informed by the second control unit 2-384 of the energy required for the operation of the first optical component 2-105. The processing program 2-PR then proceeds to step 2-ST3 to read the induced power signal 2-IPW input by the third communication element 2-343 via the first control unit 2-382.
The processing routine 2-PR proceeds to step 2-ST4, where the first control unit 2-382 determines the magnitude of the induced power signal 2-IPW and the required power for the first optical subassembly 2-105 to operate. If the induced power signal 2-IPW is larger than the energy required for the operation of the first optical component 2-105, the process 2-PR proceeds to step 2-ST5, where the sixth power signal 2-PW6 is provided to the first optical component 2-105 and the seventh power signal 2-PW7 is provided to the energy storage element 2-350. If the sensed power signal 2-IPW is less than the power required for the operation of the first optical component 2-105, the processing routine 2-PR proceeds to step 2-ST6, where the second control unit 2-384 is informed about this information by the first control unit 2-382. The processing sequence 2-PR then proceeds to step 2-ST7, at which time the energy storage element 2-350 is controlled by the second control unit 2-384 to provide a standby signal 2-BA to the first optical component 2-105.
Although in the foregoing embodiments, only one of the direct current and the alternating current is output to the single coil, the disclosure is not limited thereto. For example, FIG. 10 is a schematic diagram of the input signal 2-IN. IN some embodiments, the input signal 2-IN may be a superposition of the drive signal 2-DR and the charge signal 2-CH. The driving signal 2-DR may be a dc signal after a certain initial period of time, and the charging signal 2-CH may be an ac signal, so that the input signal 2-IN may comprise both dc and ac signals, and the signal provided by the fourth communication element 2-344 to the third communication element 2-343 may also comprise both dc and ac signals.
In summary, the present disclosure provides a method for controlling an optical system, which includes providing an input signal from an external circuit to the optical system, receiving an optical signal by using the first optical element, and converting the optical signal into an image signal to be provided to the external circuit.
