In some embodiments, the optical system 2-100 may mainly include a top case 2-110, a base 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 main axis 2-O. The optical system 2-100 may be disposed on an electronic device, for example, but not limited to, a mobile phone, a tablet computer, a notebook computer, and the like.
The optical system 2-100 may be used to drive the second optical element 2-900, or may be used to drive various optical elements (e.g., lenses, mirrors, prisms, beam splitters, diaphragms, liquid lenses, image sensors, camera modules, ranging modules, etc.). It should be noted that the definition of optical element herein is not limited to elements related to visible light, elements related to invisible light (e.g., infrared light, ultraviolet light), etc. may also be included in the present disclosure.
In some embodiments, the top case 2-110, the base 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 component 2-105 for driving the aforementioned second optical element 2-900 to move in the direction X, Y, Z. In addition, the top case 2-110 and the base 2-120 may be fixed on the first substrate 2-200, so the top case 2-110, the base 2-120 and the first substrate 2-200 may be collectively referred to as a fixing portion 2-F. The first movable part 2-400 and the second movable part 2-130 can move relative to the fixed part 2-F. In some embodiments, the second movable portion 2-130 may also be movable relative to the first movable portion 2-400.
It should be understood that the top case 2-110 and the base 2-120 are respectively formed with a top case opening and a base opening, the center of the top case opening corresponds 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 aligned along the spindle 2-O), the base opening corresponds 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, for example, may be arranged in the direction of the main axis 2-O (e.g., Z direction), so that the second optical element 2-900 disposed in the second optical element 2-900 may perform focusing with the first optical element 2-500 in the main axis 2-O direction.
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 assembly 2-D2 for driving the second movable portion 2-130 to move relative to the fixed portion 2-F.
The first magnetic element 2-150 and the first coil 2-140 may be located on the fixed portion 2-F and the second movable portion 2-130, respectively, or the positions may be interchanged, depending on design requirements. It should be appreciated 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 an Auto Focus (AF) or an optical anti-shake (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 the like.
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 may 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 materials and suspended in the fixed portion 2-F. When the first coil 2-140 is energized, the first coil 2-140 acts on the magnetic field of the first magnetic element 2-150 and generates 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 spindle 2-O direction relative to the fixed portion 2-F, so as to achieve the auto-focusing effect.
In some embodiments, a first sensing element 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 can include a first sensing element 2-SE11, a second sensing element 2-SE12. The first sensing element 2-SE11 may be arranged on the fixed part 2-F (e.g. the first substrate 2-200 or the base 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 magneto-resistive effect Sensor (Magnetoresistance Effect Sensor, MR Sensor), a giant magneto-resistive effect Sensor (Giant Magnetoresistance Effect Sensor, GMR Sensor), a tunneling magneto-resistive effect Sensor (Tunneling Magnetoresistance Effect Sensor, TMR Sensor), or a magnetic flux Sensor (Fluxgate Sensor).
The second sensing element SE12 may include a magnetic element, and the first sensing element 2-SE11 may sense a change in the magnetic field caused by the second sensing element 2-SE12 when the second movable portion 2-130 is movable, so as to obtain a position of the second movable portion 2-130 relative to the fixed portion 2-F. In some embodiments, other similar 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 device can be used to sense the motion of the first movable portion 2-400 or the second movable portion 2-130 relative to the fixed portion 2-F in different dimensions, such as translation in the X direction (first dimension), translation in the Y direction (second dimension), translation in the Z direction (third dimension), rotation about the Z 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 to the base 2-120 by an adhesive manner. In this 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 component 2-D2, so as to control the movement of the second movable portion 2-130 in the X, Y or Z direction, thereby realizing an auto-focus (AF) or optical anti-shake (OIS) function.
In some embodiments, the circuit assembly 2-210 is, for example, a flexible printed circuit board (FPC), which may be adhesively secured to the securing portion 2-F. In the present embodiment, the circuit assembly 2-210 is electrically connected to other electronic components or electronic devices disposed inside or outside the optical component driving mechanism 2-100. 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 realizing the functions of Auto Focus (AF) or optical anti-shake (OIS).

The ninth coil element 2-318, the first optical element 2-500 may be disposed 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 may have 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 part 2-400 may comprise plastic to avoid magnetic interference. The first optical element 2-500 and the filter element 2-510 may be arranged (e.g. connected) on 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, for example, 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, so as to achieve an optical anti-shake (OIS) effect, for example. The first optical element 2-500 may be 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 on the first movable portion 2-400, and the second communication element 2-342 may be fixed on the fixed portion 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 assembly 2-340A. The image signal is outputted to an external circuit for communication via the first signal (radio electromagnetic wave) transmitted by the first communication component 2-340A. For example, the optical systems 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 element 2-342 may be electrically connected to the external circuit of the electronic device. The first communication element 2-341 and the second communication element 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 include, for example, bluetooth (Bluetooth), wireless area network (wireless local area network, WLAN), wireless wide area network (wireless wide area network, WWAN), etc., depending on design requirements.
The filter element 2-510 may allow only light of a specific wavelength to pass therethrough and filter out other light having an undesired wavelength, i.e. may filter out 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 to this. 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 may be made closer to the naked eye.
The second substrate 2-600 may be disposed on the first movable portion 2-400, the elastic component 2-700 may be used to movably connect the second substrate 2-600 with the fixed portion 2-F (e.g. the base 2-120), and the first driving component 2-800 may be used to drive the first movable portion 2-400 to move relative to the fixed portion 2-F or relative to the second movable portion 2-130.
In some embodiments, the first driving assembly 2-800 may be used to drive the first movable portion 2-400 to move relative to the fixed portion 2-F. In some embodiments, the material of the driving element in the first driving assembly 2-800 may comprise a shape memory alloy (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 heating and raising the temperature and restore the original shape of the shape memory alloy before deformation. For example, when the shape memory alloy is subjected to a limited plastic deformation at a temperature below the transformation temperature, it can be restored to its original shape before deformation by heating.
The elastic member 2-700 may be movably coupled to the second substrate 2-600 through the first driving member 2-800. When the driving element in the first driving component 2-800 is deformed, the second substrate 2-600 and the elastic component 2-700 can be driven to move relatively, so that the first movable part 2-400 is allowed to move relative to the fixed part 2-F, and the first optical element 2-500 arranged on the first movable part 2-400 is moved together, so that the effect of preventing optical vibration of hands is achieved.
Fig. 5A is a schematic diagram of some elements of the optical system 2-100A. The elements of the optical system 2-100A may be substantially similar to the optical system 2-100 described previously, and only partial element positional relationships are shown in fig. 5A. The top case 2-110 of the fixing 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 when viewed along the direction of the main axis 2-O (Z direction), 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. In addition, the top case 2-110 further includes a first corner 2-C1, a second corner 2-C2, a third corner 2-C3, and a fourth corner 2-C4. The first corner 2-C1 is positioned between the fourth side 2-S4 and the first side 2-S1, the second corner 2-C2 is positioned between the first side 2-S1 and the second side 2-S2, the third corner 2-C3 is positioned between the second side 2-S2 and the third side 2-S3, and the fourth corner 2-C4 is positioned between the third side 2-S3 and the 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, but not overlap the first optical element 2-500, as seen along the main axis 2-O, to avoid magnetic interference. The spindle 2-O may pass through the ninth coil element 2-318, 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 electromagnetic induction.
However, the disclosure is not limited thereto. For example, FIG. 5B is a schematic diagram of some of the elements of optical systems 2-100B. The elements of the optical system 2-100B may be substantially similar to the optical system 2-100 described above, with only partial elements being shown in positional relationship 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, the second coil element 2-320 at least partially overlap, the third coil element 2-312, the fourth coil element 2-322 at least partially overlap, the fifth coil element 2-314, the sixth coil element 2-324 at least partially overlap, the seventh coil element 2-316, the eighth coil element 2-326 at least partially overlap, and the ninth coil element 2-318, the tenth coil element 2-328 at least partially overlap, as viewed along the bobbin 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, 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, 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 assembly 2-340A and the second communication assembly 2-340B can form a communication module 2-340 for connecting to external circuits.
Furthermore, the first optical element 2-500 does not overlap at least partially with the first coil assembly 2-W1 or the second coil assembly 2-W2, as seen in the direction of the main axis 2-O (Z direction), 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 electromagnetic induction.
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, as viewed in the direction of the main shaft 2-O. In addition, the first coil element 2-310, the second coil element 2-320 are positioned at the first corner 2-C1, the third coil element 2-312, the fourth coil element 2-322 are positioned at the second corner 2-C2, the fifth coil element 2-314, the sixth coil element 2-324 are positioned at the third corner 2-C3, the seventh coil element 2-316, and the eighth coil element 2-326 are positioned at the 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). Thus, magnetic interference between the coils can be avoided.
The second coil assembly 2-W2 (the fourth communication element 2-344) can be used to wirelessly transmit a power signal to the first coil assembly 2-W1 (the third communication element 2-343), i.e. the power signal transmitted by the external circuit through 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 assembly 2-W2, the first coil assembly 2-W1 generates an induced electromotive force (induced electromotive force) accordingly, so that the power signal can be transmitted to the first coil assembly 2-W1 wirelessly.
Alternatively, an additional magnetic element, such as a magnet or a ferromagnetic material (e.g., iron, cobalt, nickel, etc.), may be provided on the first movable portion 2-400, and the second coil assembly 2-W2 may act as an electromagnet when a direct current signal is provided to the second coil assembly 2-W2, and may 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, so as to achieve miniaturization.
In addition, a first support member 2-360 and a second support member 2-370 may be disposed between the first movable portion 2-400 and the fixed portion 2-F (e.g., the first substrate 2-200). The first support assembly 2-360 may include a first support element 2-362, a second support element 2-364, and a third support element 2-366 that are spherical. The second support assembly 2-370 may comprise a fourth support element 2-372, a fifth support element 2-374, a sixth support element 2-376 in the form of balls. The first support element 2-362, the second support element 2-364, the third support element 2-366, the fourth support element 2-372, the fifth support element 2-374, the sixth support element 2-376 may be located at a side or corner of the first movable portion 2-400 or the top case 2-110 to limit the position of the first movable portion 2-400 relative to the fixed portion 2-F.
In some embodiments, the first support element 2-362, the second support element 2-364, the third support element 2-366 may have substantially the same diameter, the fourth support element 2-372, the fifth support element 2-374, the sixth support element 2-376 may also have substantially the same diameter, and the diameters of the first support element 2-362, the second support element 2-364, the third support element 2-366 and the fourth support element 2-372, the fifth support element 2-374, the sixth support element 2-376 may be different.
For example, the diameters of the first support element 2-362, the second support element 2-364, the third support element 2-366 are larger than the diameters of the fourth support element 2-372, the fifth support element 2-374, the sixth support element 2-376. Thus, in the rest state, the first support element 2-362, the second support element 2-364, the third support element 2-366 can directly contact the first movable portion 2-400 and the fixed portion 2-F, while the fourth support element 2-372, the fifth support element 2-374, the sixth support element 2-376 directly contact the fixed portion 2-F only 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 broken lines in fig. 5B, the first support element 2-362, the second support element 2-364, 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, the sixth support element 2-376. In addition, the fourth support element 2-372, the fifth support element 2-374, the sixth support element 2-376 form a second triangular structure 2-378, and the second triangular structure 2-378 does not overlap the first support element 2-362, the second support element 2-364, 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 is rotated by the rotation axis formed by the connection line of the first support element 2-362 and the second support element 2-364. In this case, by the aforementioned positional relationship (the first triangular structure 2-368 and the fifth supporting element 2-374 do not overlap), the fifth supporting element 2-374 can serve as a limiting structure to limit the maximum rotatable range of the first movable portion 2-400, thereby avoiding collision of the first movable portion 2-400 with other elements.
In the following embodiments, the first support element 2-360 and the second support element 2-370 in this embodiment may also be provided, and the first support element 2-360 and the second support element 2-370 are omitted for brevity in the following description.
Fig. 5C is a schematic diagram of some of the elements of the optical system 2-100C. The elements of the optical systems 2-100C may be substantially similar to the optical systems 2-100 described above, with only partial element positional relationships shown in fig. 5C. In fig. 5C, the aforementioned ninth coil element 2-318, tenth coil element 2-328 may be omitted. Further, 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 different from 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.
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 assembly 2-W1 and the second coil assembly 2-W2 do not overlap completely, as seen in the direction of the main shaft 2-O, but are partially exposed from the second coil assembly 2-W2. Thus, the size of each coil on the first movable portion 2-400 can be reduced, and miniaturization can be achieved.
Although each coil element in the foregoing embodiments is disposed at a corner of the top case 2-110, the present disclosure is not limited thereto. For example, FIG. 5D is a schematic diagram of some of the elements of optical systems 2-100D. The elements of the optical systems 2-100D may be substantially similar to the optical systems 2-100 described above, with only partial element positional relationships shown in fig. 5D.
In fig. 5D, there are also included eleventh coil elements 2-311, twelfth coil elements 2-321 provided on the first side 2-S1, and thirteenth coil elements 1-315, fourteenth coil elements 1-325 provided on the third side 2-S3. The eleventh coil element 2-311, thirteenth coil element 1-315 may be part of the first coil assembly 2-W1, while the twelfth coil element 2-321, fourteenth coil element 1-325 may be part of the second coil assembly 2-W2. The eleventh coil element 2-311, thirteenth coil element 1-315 of the first coil assembly 2-W1 may be disposed on the first movable portion 2-400, and the twelfth coil element 2-321, fourteenth coil element 1-325 of the second coil assembly 2-W2 may be disposed on the fixed portion 2-F.
By providing additional eleventh coil elements 2-311, twelfth coil elements 2-321, thirteenth coil elements 1-315, fourteenth coil elements 1-325 at the sides, the maximum power of the signal transferred from the second coil assembly 2-W2 to the first coil assembly 2-W1 can be increased to enhance the transfer effect. In addition, the coil elements are arranged at the side edges, so that the space of the side edges can be further utilized, and the miniaturization is achieved.
Fig. 6A, 6B are schematic side views of the optical systems 2-100D as viewed from different directions, with only some elements shown for brevity. 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 of the elements of optical systems 2-100E. The elements of the optical systems 2-100E may be substantially similar to the optical systems 2-100 described above, with only partial elements being shown in positional relationship in FIG. 5E. In fig. 5E, the distance between the first coil element 2-310, the eleventh coil element 2-311, the third coil element 2-312 may be different from the distance between the second coil element 2-320, the twelfth coil element 2-321, the fourth coil element 2-322 in the X direction.
For example, in the X direction (first direction), the distance 2-L1 of the center 2-310C of the first coil element 2-310 from the center 2-312C of the third coil element 2-312 is different from the distance 2-L2 of the center 2-320C of the second coil element 2-320 from the center 2-322C of the fourth coil element 2-322, e.g., the distance 2-L1 may be less than the distance 2-L2, and the eleventh coil element 2-311 may overlap the twelfth coil element 2-321. Similar positional relationships can be provided between 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, and will not be described 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, 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, 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 simplicity. 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 offset from the sixth coil element 2-324, and the seventh coil element 2-316 may be offset from the eighth coil element 2-326. In the X-direction (first direction), the distance 2-L1 of the center 2-310C of the first coil element 2-310 from the center 2-312C of the third coil element 2-312 is different from the distance 2-L2 of the center 2-320C of the second coil element 2-320 from 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 of the elements of the optical systems 2-100F. The elements of the optical systems 2-100F may be substantially similar to the optical systems 2-100 described above, with only partial elements being shown in positional relationship in FIG. 5F. In fig. 5F, in the Y-direction, the distance 2-L3 of the center 2-312C of the third coil element 2-312 from the center 2-314C of the fifth coil element 2-314 is different from the distance 2-L4 of the center 2-322C of the fourth coil element 2-322 from the center 2-324C of the sixth coil element 2-324, e.g., the distance 2-L3 may be smaller than the distance 2-L4. Similar positional relationships may also be provided between the first coil element 2-310, the second coil element 2-320, the seventh coil element 2-316, and the eighth coil element 2-326, which are not described herein.
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 of the elements of optical systems 2-100G. The elements of the optical systems 2-100G may be substantially similar to the optical systems 2-100 described above, with only partial element positional relationships shown in fig. 7A. The first movable part 2-400 of the optical system 2-100G may have a first magnetism isolating element 2-332 thereon. The first coil assembly 2-W1 may be disposed on the first side 2-400A of the first movable portion 2-400, and the second coil assembly 2-W2 may be disposed on the third side 2-200A of the first substrate 2-200 with the first side 2-400A facing in the same direction as the third side 2-200A. The first magnetism blocking element 2-332 is at least partially disposed 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 magnetism blocking 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 spindle 2-O (Z direction). Furthermore, the first magnetism isolating element 2-332, the first optical element 2-500, and the first coil component 2-W1 at least partially overlap in the X-direction or the Y-direction.
In addition, the first magnetism isolating element 2-332 may have a magnetically permeable material (e.g., metal). By the above overlapping positional 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 magnetism 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 achieved.
Fig. 7B is a schematic diagram of some of the elements of the optical system 2-100H. The elements of the optical systems 2-100H may be substantially similar to the optical systems 2-100 described above, with only partial element positional relationships shown in fig. 7B. The second magnetism isolating element 2-334 may be provided on the first movable portion 2-400 of the optical system 2-100H, for example, on a different side of the first movable portion 2-400 from the first coil element 2-310 and the third coil element 2-312. The first coil assembly 2-W1 may be disposed on the first side 2-400A of the first movable portion 2-400, and the second coil assembly 2-W2 may be disposed on the third side 2-200A of the first substrate 2-200 with the first side 2-400A facing in the same direction as the third side 2-200A.
The second magnetically isolated element 2-334 may be of a similar material as the first magnetically isolated element 2-332 described previously. The second magnetism isolating element 2-334 is disposed at least partially 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 magnetism isolating element 2-334 at least partially overlaps the first optical component 2-105 (e.g., the first optical element 2-500) in the direction of the spindle 2-O (Z direction). The second magnetism isolating element 2-334 is disposed at least partially between the first coil assembly 2-W1 and the second coil assembly 2-W2 in the direction of the spindle 2-O. By the above overlapping positional 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 of the elements of optical systems 2-100I. The elements of the optical systems 2-100I may be substantially similar to the optical systems 2-100 described above, with only partial element positional relationships shown in fig. 7C. The first movable portion 2-400 of the optical system 2-100I may have a third magnetism isolating element 2-336, for example, partially embedded in the first movable portion 2-400 and partially exposed from the first movable portion 2-400. The third magnetically isolated element 2-336 may be of a similar material as the first magnetically isolated element 2-332 described previously. The third magnetically isolated element 2-336 is at least partially disposed between the first optical assembly 2-105 (e.g., the first optical element 2-500) and either the first coil assembly 2-W1 or the second coil assembly 2-W2.
Although in the foregoing embodiments, the first coil assembly 2-W1 is disposed on the side of the first movable portion 2-400 facing away from the second coil assembly 2-W2, the disclosure is not limited thereto. For example, in fig. 7C, the first coil assembly 2-W1 may be disposed on the second side 2-400B of the first movable portion 2-400, while the second coil assembly 2-W2 may be disposed on the third side 2-200A of the first substrate 2-200, with the second side 2-400B facing the third side 2-200A, i.e., in the opposite direction.
In addition, the first coil block 2-W1, the second coil block 2-W2 and the first optical element 2-500 are disposed on opposite sides of the third magnetism isolating element 2-336. By the above overlapping positional 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 magnetic separation elements 2-332, 2-334, 336 may be collectively referred to as a magnetic separation assembly, and although the foregoing embodiments only show embodiments in which each optical system has a single magnetic separation element, it should be appreciated that the first, second and third magnetic separation elements 2-332, 2-334, 2-336 may be present at the same time, e.g., the first, second and third magnetic separation elements 2-332, 2-334, 2-336 may be provided in the same optical system at the same time to achieve a further magnetic separation 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 the first communication element 2-341 and the second communication element 2-342. It should be noted that the first communication element 2-341, the second communication element 2-342, and the energy storage element 2-350 are also applicable to the foregoing embodiments, and are only shown in fig. 7C for brevity. The energy storage element 2-350 may be, for example, a battery, and may be electrically connected to the third communication element 2-343 (the first coil assembly 2-W1) to supply power to 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 avoid interference of external signals on the second communication element 2-342, and allow the second communication element 2-342 to only receive the signals transmitted by the first communication element 2-341, thereby improving the quality of signal transmission.
Fig. 8A is a diagram showing the connection between the optical system 2-100 and the external circuit 2-EXT. The external circuit 2-EXT may be configured to provide the input signal 2-IN to the optical system 2-100, and the first optical element 2-500 of the first optical assembly 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. Specifically, the image signal IS may be input to the first communication component 2-340A and the image signal 2-IS converted into the first signal 2-SI1 at the first communication element 2-341 of the first communication component 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 output to the external circuit 2-EXT for communication. Thus, the wiring for connecting the elements can be omitted, and miniaturization can be achieved.
Fig. 8B is a detailed schematic diagram of some of the elements of fig. 8A. Specifically, when the second communication component 2-340B of the optical system 2-100 receives the input signal 2-IN input from the external circuit 2-EXT, the input signal 2-IN can be converted into the second signal 2-SI2 and the power signal 2-PW0 by the fourth communication component 2-344 of the second communication component 2-340B, the second signal 2-SI2 and the power signal 2-PW0 are wirelessly provided from the fourth communication component 2-344 to the third communication component 2-343, the second signal 2-SI2 and the power signal 2-PW0 are converted into the third signal 2-SI3 and the power signal 2-IPW by the third communication component 2-343, and the third signal 2-SI3 and the power signal 2-IPW are input to the first optical component 2-105. Thus, the wiring for connecting the elements can be omitted, and miniaturization can be achieved.
It should be noted that the power signals 2-PW0 and the second signals 2-SI2 have different frequencies and different powers, so that the power signals 2-PW0 and the second signals 2-SI2 can be used to transmit different information, respectively. For example, the power of the power 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 mainly through the power signal 2-PW0 to achieve the wireless charging function. In addition, the second signal 2-SI2 may be used to transmit signals that control the first optical component 2-105, thereby eliminating the need to control the first optical component 2-105 via additional lines.
It should be noted that when the power supply signal 2-PW0 is supplied to 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 of the aforementioned fourth communication element 2-344, the power supply signal 2-PW0 may be divided into the first power supply signal 2-PW1, the second power supply signal 2-PW2, the third power supply signal 2-PW3, the fourth power supply signal 2-PW4, and the fifth power supply signal 2-PW5, which are supplied to 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, respectively. Next, the second coil element 2-320, the fourth coil element 2-322, the sixth coil element 2-324, the eighth coil element 2-326, the tenth coil element 2-328 may provide the first power signal 2-PW1, the second power signal 2-PW2, the third power signal 2-PW3, the fourth power signal 2-PW4, 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, by wireless means (e.g., electromagnetic induction).
It should be noted that in normal conditions (e.g., the first movable portion 2-400 does not perform an out-of-limit motion relative to the fixed portion 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 generates an inductive power signal 2-IPW that is greater than the energy 2-EN (not shown) required by the first optical element 2-105 to operate. In other words, (2-IPW) > (2-EN). Thereby, it is ensured that the first optical component 2-105 has sufficient energy to operate.
Under normal conditions, the excess energy in the inductive power supply signal 2-IPW may be transferred to the energy storage element 2-350 for storage. For example, the inductive power supply signal 2-IPW may be converted into two parts of the sixth power supply signal 2-PW6 and the seventh power supply 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 supply signal 2-PW6 may be provided to the first optical component 2-105 and the seventh power supply 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 portion 2-400 is impacted to perform an out-of-limit motion (in an abnormal situation) with respect to the fixed portion 2-F, each coil element in the third communication element 2-343 may not be aligned with each coil element in the fourth communication element 2-344, and thus 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 smaller than the energy 2-EN required for the operation of the first optical assembly 2-105. In this case, the standby signal 2-BA, which may be, for example, a standby current, may be provided to the first control unit 2-382 via the energy storage element 2-350 for compensation. In this case, the sum of the inductive 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), so as to ensure that the first optical component 2-105 can operate normally.
In addition, the third communication element 2-343 may further comprise a start-up coil element 2-346, and the fourth communication element 2-344 may wirelessly provide the second signal 2-SI2 to the start-up coil element 2-346, and the start-up coil element 2-346 may convert the second signal 2-SI2 into the third signal 2-SI3 for providing 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 assembly 2-105 when the first optical assembly 2-105 is turned off.
Fig. 8C to 8E are schematic views of the positional relationship of 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, in the Z-direction, the first coil element 2-310, the third coil element 2-312, the fifth coil element 2-314, 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, the eighth coil element 2-326, and the ninth coil element 2-318 is aligned with the tenth coil element 2-328, while the first movable portion 2-400 is located at a preset position with respect to the fixed portion 2-F. The greater the area of overlap between the coil elements, the higher the strength of the power signal transmitted. In other words, the fifth power supply signal 2-PW5 is larger than the first power supply signal 2-PW1 and the third power supply signal 2-PW3.
In fig. 8D, the first movable portion 2-400 is moved in the-Y direction with respect to the top case 2-100, so that the first movable portion 2-400 is positioned at the first limit position with respect to the fixed portion 2-F. Compared to the situation of fig. 8C, the area where the first coil element 2-310, the third coil element 2-312 overlaps the second coil element 2-320, the fourth coil element 2-322 increases, and the area where the fifth coil element 2-314, the seventh coil element 2-316, the ninth coil element 2-318 overlaps the sixth coil element 2-324, the eighth coil element 2-326, the tenth coil element 2-328 decreases, so that the first power supply signal 2-PW1 is larger than the third power supply signal 2-PW3 and the fifth power supply signal 2-PW5, and the area where the fifth coil element 2-314 overlaps the sixth coil element 2-324 is smaller than the area where the ninth coil element 2-318 overlaps the tenth coil element 2-328, so that the third power supply signal 2-3 is smaller than the fifth power supply signal 2-PW5.
On the contrary, as shown in fig. 8E, the first movable portion 2-400 moves in the Y direction relative to the top case 2-100, so that the first movable portion 2-400 is positioned at the second limit position relative to the fixed portion 2-F. The first limit position is different from the second limit position, and the preset position is located between the first limit position and the second limit position. Compared to the situation of fig. 8C, the areas where the fifth coil element 2-314, the seventh coil element 2-316 overlaps the sixth coil element 2-324, the eighth coil element 2-326 are increased, and the areas where the first coil element 2-310, the third coil element 2-312, the ninth coil element 2-318 overlaps the second coil element 2-320, the fourth coil element 2-322, the tenth coil element 2-328 are decreased, so that the third power supply signal 2-PW3 is larger than the first power supply signal 2-PW1, the fifth power supply signal 2-PW5, and the first power supply signal 2-1 is smaller than the fifth power supply signal 2-PW5 at this time because the area where the first coil element 2-310 overlaps the second coil element 2-320 is smaller than the area where the ninth coil element 2-318 overlaps the tenth coil element 2-328.
In addition, the fourth communication element 2-344 may transmit the power signal to the third communication element 2-343 by means of alternating current, or may transmit direct current to some coil elements in the fourth communication element 2-344 to serve as electromagnets at the same time. The coil element passing through the direct current can generate electromagnetic driving force with other magnetic elements on the first movable part 2-400 so as 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 to achieve miniaturization.
For example, when the first movable portion 2-400 is located at a predetermined position relative to the fixed portion 2-F, as shown in fig. 8C, direct current is passed through 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 alternating current is passed through the tenth coil element 2-328 to transmit power signals through the ninth coil element 2-328 having the largest overlapping area, the tenth coil element 2-328, and other coil elements having smaller overlapping areas can be used to drive the first movable portion 2-400.
Similarly, as shown in fig. 8D, when the first movable portion 2-400 is positioned at the first limit position with respect to the fixed portion 2-F, alternating current is passed through the second coil element 2-320, the fourth coil element 2-322, and direct current is passed through the sixth coil element 2-324, the eighth coil element 2-326, the tenth coil element 2-328 to transmit a power signal through 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 having the largest overlapping area, and other coil elements having smaller overlapping areas can be used to drive the first movable portion 2-400.
Similarly, as shown in fig. 8E, when the first movable portion 2-400 is positioned at the second limit position with respect to the fixed portion 2-F, alternating current is passed through the sixth coil element 2-324, the eighth coil element 2-326, and direct current is passed through the second coil element 2-320, the fourth coil element 2-322, the tenth coil element 2-328 to transmit a power signal through the fifth coil element 2-314, the sixth coil element 2-324, the seventh coil element 2-316, the eighth coil element 2-326 having the largest overlapping area, and other coil elements having smaller overlapping areas can be used to drive the first movable portion 2-400.
Fig. 9 is a flowchart of the processing procedure 2-PR when the optical system 2-100 is in operation. The process sequence 2-PR starts in step 2-ST1, in which the energy required for the operation of the first optical component 2-105 is determined by the second control unit 2-384. The processing procedure 2-PR then proceeds to step 2-ST2, where the energy required for the operation of the first optical component 2-105 is informed to the first control unit 2-382 by the second control unit 2-384. Next, the processing program 2-PR proceeds to step 2-ST3, and the inductive power supply signal 2-IPW inputted to the third communication element 2-343 is read by the first control unit 2-382.
Then, the processing procedure 2-PR proceeds to step 2-ST4, and the first control unit 2-382 determines the amount of energy required for the operation of the inductive power supply signal 2-IPW and the first optical component 2-105. If the sensed power signal 2-IPW is greater than the energy required to operate the first optical device 2-105, the process 2-PR proceeds to step 2-ST5, where the sixth power signal 2-PW6 is provided to the first optical device 2-105 and the seventh power signal 2-PW7 is provided to the energy storage device 2-350. If the sensed power signal 2-IPW is less than the energy required to operate the first optical element 2-105, the process 2-PR proceeds to step 2-ST6, where the second control unit 2-384 is informed by the first control unit 2-382. The process sequence 2-PR then proceeds to step 2-ST7, where the energy storage element 2-350 is controlled by the second control unit 2-384 to provide the standby signal 2-BA to the first optical assembly 2-105.
Although in the foregoing embodiments, only one of the direct current or the alternating current is output to the single coil is described, the present disclosure is not limited thereto. For example, FIG. 10 is a schematic diagram of input signals 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 direct current after a period of start time has elapsed, and the charging signal 2-CH may be an alternating current, so that the input signal 2-IN may include both a direct current and an alternating current, and so that the signal provided by the fourth communication element 2-344 to the third communication element 2-343 may also include a direct current signal and an alternating current signal.
In summary, the present disclosure provides a method for controlling an optical system, which includes providing an input signal from an external circuit to an optical system, receiving an optical signal using the first optical component, and converting the optical signal into an image signal to be provided to the external circuit.
