[0095] The following describes the optical component driving mechanism according to an embodiment of the present invention. However, it will be readily apparent that the embodiments of the present invention provide many suitable inventive concepts and can be implemented in a wide range of specific contexts. The specific embodiments disclosed are merely illustrative of the use of the invention in a particular manner and are not intended to limit the scope of the invention.

[0096] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the relevant art and the context of this disclosure, and should not be interpreted in an idealized or overly formal manner, unless specifically defined herein.

[0097] Figure 1 , 2 The diagrams and exploded views respectively illustrate an optical component driving mechanism 100 according to an embodiment of the present invention. The aforementioned optical component driving mechanism 100 can be installed in a vehicle (e.g., a car, motorcycle) or a portable device (e.g., a smartphone, laptop computer) and can be electrically connected to a processor (not shown). The optical component driving mechanism 100 can provide light rays to an object and receive the light rays reflected by the object. The processor can calculate the outline of the object based on information such as the time difference between emission and reception, or the intensity of the received light rays.

[0098] like Figure 1 , 2 As shown, the optical component driving mechanism 100 mainly includes a light emitter 110, a light receiver 120, and a rotating module 130. The light emitter 110 and the light receiver 120 are disposed on the rotating module 130. The light emitter 110 can emit light in a direction away from the optical component driving mechanism 100 from one side 101, and the light receiver 120 can receive the same type of light incident on the optical component driving mechanism 100 from the same side 101. For example, the aforementioned light can be infrared light, white light, or laser light.

[0099] The rotating module 130 includes a fixed part 131, a movable part 132, and a drive assembly 133. The fixed part 131 may be a base, and the movable part 132 may be a support assembly. The movable part 132 is movably connected to the fixed part 131.

[0100] like Figure 2 , 3As shown, in this embodiment, the movable part 132 has a metal substrate 1321, an insulating layer 1322, and a circuit layer 1323. The insulating layer 1322 is disposed between the metal substrate 1321 and the circuit layer 1323, and the aforementioned light emitter 110 and light receiver 120 can be disposed on the insulating layer 1322 and electrically connected to the circuit layer 1323.

[0101] In this embodiment, the metal substrate 1321 is composed of a flexible spring sheet, including at least one first connecting segment 1321A, at least one second connecting segment 1321B, and at least one string segment 1321C. The first connecting segment 1321A is fixed to the fixing part 131, the insulating layer 1322 is disposed on the second connecting segment 1321B, and the string segment 1321C connects the first connecting segment 1321A and the second connecting segment 1321B. Therefore, the light emitter 110 and the light receiver 120 can be suspended on the fixing part 131 through the metal substrate 1321 of the movable part 132.

[0102] The drive assembly 133 includes at least one first electromagnetic drive assembly 1331, at least one second electromagnetic drive assembly 1332, and at least one magnetically conductive assembly 1333. The first electromagnetic drive assembly 1331 is disposed on the fixed portion 131, and the second electromagnetic drive assembly 1332 is disposed on the movable portion 132 and corresponds to the first electromagnetic drive assembly 1331. The second engaging segment 1321B can be driven to move relative to the fixed portion 131 by the first electromagnetic drive assembly 1331 and the second electromagnetic drive assembly 1332.

[0103] In detail, in this embodiment, the first electromagnetic drive component 1331 is a magnet, and the second electromagnetic drive component 1332 is a coil. When current flows through the second electromagnetic drive component 1332, an electromagnetic interaction is generated between the first electromagnetic drive component 1331 and the second electromagnetic drive component 1332, thereby driving the second connecting segment 1321B to rotate relative to the fixed part 131 around a first rotating axis 11.

[0104] A magnetically conductive component 1333 is disposed adjacent to the first electromagnetic drive component 1331 to enhance the magnetic thrust. In some embodiments, the first electromagnetic drive component 1331 is a coil, and the second electromagnetic drive component 1332 is a magnet.

[0105] Because the light emitter 110 and the light receiver 120 are mounted on the second junction section 1321B, when the second junction section 1321B is driven to rotate, the light emitter 110 and the light receiver 120 will also rotate together. In this way, the scanning range of the optical component drive mechanism 100 can be increased, and the situation where the position of light reflected by the object cannot be received by the light receiver 120 can be reduced.

[0106] In this embodiment, the insulating layer 1322 and the second electromagnetic drive assembly 1332 are located on opposite sides of the metal substrate 1321, that is, the metal substrate 1321 is disposed between the insulating layer 1322 and the second electromagnetic drive assembly 1332. Furthermore, the light emitter 110 and the light receiver 120 can be arranged along the first rotation axis 11, such that the first rotation axis 11 passes through the light emitter 110 and the light receiver 120. In some embodiments, the light emitter 110 and the light receiver 120 can also be disposed on opposite sides of the first rotation axis 11, and the distance between the light emitter 110 and the first rotation axis 11 is equal to the distance between the light receiver 120 and the first rotation axis 11.

[0107] Please see Figure 4 , 5 In another embodiment of the present invention, the optical component driving mechanism 200 mainly includes a light emitter 210, a light receiver 220, and a rotation module 230. The light emitter 210 and the light receiver 220 are disposed on the rotation module 230, and the rotation module 230 can drive the light emitter 210 and the light receiver 220 to rotate around a first rotation axis 21 and a second rotation axis 22, wherein the first rotation axis 21 is perpendicular to the second rotation axis 22.

[0108] The rotating module 230 includes a fixed part 231, a movable part 232, and a drive assembly 233. The fixed part 231 includes a base 2311 and a frame 2312, which are fixedly connected. The movable part 232 includes a support assembly 2321 and a load-bearing assembly 2322, and the movable part 232 is movably connected to the fixed part 231.

[0109] like Figures 5-7 As shown, in this embodiment, the movable part 232 has a metal substrate 2324, an insulating layer 2325, and a circuit layer 2326. The insulating layer 2325 is disposed between the metal substrate 2324 and the circuit layer 2326, and the aforementioned light emitter 210 and light receiver 220 can be disposed on the insulating layer 2325 and electrically connected to the circuit layer 2326.

[0110] In this embodiment, the metal substrate 2324 is composed of a flexible spring sheet, including at least one first connecting segment 2324A, at least one second connecting segment 2324B, and at least one string segment 2324C. The first connecting segment 2324A is fixed to the frame 2312, the insulating layer 2325 is disposed on the second connecting segment 2324B, and the string segment 2324C connects the first connecting segment 2324A and the second connecting segment 2324B. Therefore, the light emitter 210 and the light receiver 220 can be suspended on the fixed part 231 via the metal substrate 2324 of the movable part 232.

[0111] Support component 2321 connects to second coupling segment 2324B, and second coupling segment 2324B is located between support component 2321 and carrier component 2322. Drive component 233 includes at least one first electromagnetic drive component 2331A, at least one first electromagnetic drive component 2331B, at least one second electromagnetic drive component 2332A, at least one second electromagnetic drive component 2332B, and a circuit board 2333. First electromagnetic drive components 2331A and 2331B are fixed to support component 2321 and are respectively disposed on different surfaces of support component 2321. Circuit board 2333 is sandwiched between base 2311 and frame 2312. Second electromagnetic drive components 2332A and 2332B are disposed on circuit board 2333 and pass through opening 2313 in frame 2312 to correspond to first electromagnetic drive components 2331A and 2331B respectively. The second connecting section 2324B can be driven to move relative to the fixed part 231 by the first electromagnetic drive components 2331A, 2331B and the second electromagnetic drive components 2332A, 2332B.

[0112] In detail, in this embodiment, the first electromagnetic drive components 2331A and 2331B are magnets, while the second electromagnetic drive components 2332A and 2332B are coils. When current flows through the second electromagnetic drive component 2332A, an electromagnetic interaction is generated between the first electromagnetic drive component 2331A and the second electromagnetic drive component 2332A, thereby causing the second connecting segment 2324B to rotate relative to the fixed part 231 about a first rotation axis 21. When current flows through the second electromagnetic drive component 2332B, an electromagnetic interaction is generated between the first electromagnetic drive component 2331B and the second electromagnetic drive component 2332B, thereby causing the second connecting segment 2324B to rotate relative to the fixed part 231 about a second rotation axis 22.

[0113] In some embodiments, the first electromagnetic drive components 2331A and 2331B are coils, while the second electromagnetic drive components 2332A and 2332B are magnets.

[0114] Because the light emitter 210 and the light receiver 220 are mounted on the second junction section 2324B, when the second junction section 2324B is driven to rotate, the light emitter 210 and the light receiver 220 will also rotate together. In this way, the scanning range of the optical component drive mechanism 200 can be increased, and the situation where the position of light reflected by the object cannot be received by the light receiver 220 can be reduced.

[0115] The light emitter 210 and the light receiver 220 can be arranged along the first rotation axis 21, such that the first rotation axis 21 passes through the light emitter 210 and the light receiver 220. Furthermore, the light emitter 210 and the light receiver 220 are respectively disposed on both sides of the second rotation axis 22, and the distance between the light emitter 210 and the second rotation axis 22 is equal to the distance between the light receiver 220 and the second rotation axis 22.

[0116] Please see Figure 8 In another embodiment of the present invention, the optical component driving mechanism 300 mainly includes a plurality of light emitters 310 (e.g., two), a light receiver 320, and a rotating module 330. The structure of the rotating module 330 is the same as that of the rotating module 230, and therefore will not be described again here. The light receiver 320 is disposed on the movable part 332 of the rotating module 330, and the two light emitters 310 are disposed on opposite sides of the light receiver 320. By rotating the light receiver 320, the scanning range that the optical component driving mechanism 300 can scan can be increased. Furthermore, since the light receiver 320 can receive the light rays reflected after being emitted from the two light emitters 310, the contour of the object can be calculated more accurately.

[0117] Please see Figure 9 In another embodiment of the present invention, the optical component driving mechanism 400 mainly includes a light emitter 410, a plurality of light receivers 420 (for example, two), and a rotating module 430. The structure of the rotating module 430 is the same as that of the rotating module 230, and therefore will not be described again here. The light emitter 410 is disposed on the movable part 432 of the rotating module 430, and the two light receivers 420 are disposed on opposite sides of the light emitter 410, and the light receiving ranges of the two light receivers 420 can overlap. By rotating the light emitter 410, the scanning range of the optical component driving mechanism 300 can be increased.

[0118] Please see Figure 10 In another embodiment of the present invention, the optical component driving mechanism 500 mainly includes a light emitter 510, a plurality of light receivers 520 (for example, two), a rotating module 530 and a reflecting component 540, wherein the structure of the rotating module 530 is the same as that of the rotating module 230, and therefore will not be described in detail here.

[0119] The reflecting component 540 may be, for example, a mirror or a prism, and may be mounted on the rotating module 530. A light emitter 510 provides light 1000 directed towards the reflecting component 540, and after being reflected by the reflecting component 540, the light 1000 moves along a direction 1001 to the object. Two light receivers 520 are disposed on either side of the reflecting component 540, and the aforementioned light 1000, after being reflected by the object, is received by the two light receivers 520.

[0120] It should be noted that when viewed from the aforementioned direction 1001, the light emitter 510 will overlap with one of the two light receivers 520 to make efficient use of space. The optical component drive mechanism 500 in this embodiment can be used in a vehicle to free up space between the two light receivers 520 for placing other parts.

[0121] Please see Figure 11 In another embodiment of the present invention, the optical component driving mechanism 600 mainly includes a light emitter 610, a light receiver 620, a rotating module 630 and a reflection component 640, wherein the structure of the rotating module 630 is the same as that of the rotating module 230, and therefore will not be described in detail here.

[0122] The reflector 640 may be, for example, a mirror or a prism, which may be mounted on the rotating module 630. The light emitter 610 provides light 1000 directed toward the reflector 640, and after being reflected by the reflector 640, the light 1000 is directed toward an object, and after being reflected by the object, it is received by the light receiver 620.

[0123] In particular, the aforementioned light emitter 610, reflector 640 and light receiver 620 are arranged sequentially along a straight line 1002, which reduces the thickness of the optical component drive mechanism 600 and thus makes it suitable for use in portable devices.

[0124] In the aforementioned embodiments, if the light emitter is mounted on the rotating module, or if the light is reflected by the reflective components on the rotating module, the light rays incident on the object may not be horizontally offset due to the rotation. Therefore, as Figure 12 As shown, in some embodiments, an optical path adjustment component 900 may be additionally provided on the rotating module 630 (or rotating modules 230, 330, 430, 530), and the aforementioned light emitters 210, 410 or reflective components 540, 640 may be provided on the optical path adjustment component 900.

[0125] Through this optical path adjustment component 900, the reflected light ray 1000 will move in a direction 1001 parallel or perpendicular to the second rotation axis 22. The light ray incident on the object will be horizontally deflected.

[0126] like Figure 13 As shown, in some embodiments, the second rotation axis 22 can also be adjusted to be parallel or perpendicular to the moving direction 1001 after the light 1000 is reflected by changing the direction of the magnetic thrust of the drive component 233, so as to keep the light rays directed toward the object horizontally deflected.

[0127] In the foregoing embodiments, the light emitter and the light receiver may also be a supplementary lighting component (e.g., a flash) and a photosensitive component, respectively.

[0128] In summary, the present invention provides an optical component driving mechanism, including a movable part, a fixed part, a driving assembly, at least one light emitter, and at least one light receiver. The driving assembly drives the movable part to move relative to the fixed part. The light emitter provides a light beam that is directed toward an object, and after the light beam hits the object and is reflected, the light receiver receives the light beam.
