In this embodiment, the first lens driving mechanism 1-A1000 includes a first outer frame 1-A1100, a first driving component 1-A1200, a base 1-A1400, and a photosensitive component 1-A1500. The first outer frame 1-A1100 and the base 1-A1400 can be combined into a hollow box body, and the first driving component 1-A1200 can be surrounded by the first outer frame 1-A1100, so that the first driving component 1-A1200 is accommodated in the aforementioned box body. The photosensitive component 1-A1500 is arranged on one side of the box body, and the first light entrance hole 1-A1001 is formed on the first outer frame 1-A1100, and the base 1-A1400 has an opening 1-A1410 corresponding to the first light entrance hole 1-A1001. Therefore, external light can pass through the first light entrance hole 1-A1001, the first optical component 1-AS and the opening 1-A1410 in sequence to reach the photosensitive component 1-A1500 to form an image on the photosensitive component 1-A1500.
[0251] The aforementioned first driving component 1-A1200 includes a lens holder 1-A1210, a frame 1-A1220, at least one first electromagnetic driving component 1-A1230, at least one second electromagnetic driving component 1-A1240, a first elastic component 1-A1250, a second elastic component 1-A1260, a coil plate 1-A1270, multiple suspension lines 1-A1280, and a position sensing component (including multiple position detectors 1-A1290).
[0252] The lens support seat 1-A1210 has a receiving space 1-A1211 and a concave structure 1-A1212, wherein the receiving space 1-A1211 is formed in the center of the lens support seat 1-A1210, and the concave structure 1-A1212 is formed on the outer wall surface of the lens support seat 1-A1210 and surrounds the receiving space 1-A1211. The first optical component 1-AS ( Figure 2 ) can be fixed on the lens supporting seat 1-A1210 and accommodated in the accommodating space 1-A1211, and the first electromagnetic driving component 1-A1230 can be arranged in the concave structure 1-A1212.
[0253] The frame 1-A1220 has a receiving portion 1-A1221 and a plurality of grooves 1-A1222. The aforementioned lens support seat 1-A1210 is received in the receiving portion 1-A1221, and the second electromagnetic drive component 1-A1240 is fixed in the groove 1-A1222 and is adjacent to the aforementioned first electromagnetic drive component 1-A1230.
[0254] Through the electromagnetic interaction between the first electromagnetic drive component 1-A1230 and the second electromagnetic drive component 1-A1240, the lens support 1-A1210 and the first optical component 1-AS disposed on the lens support 1-A1210 can be driven to move along the Z-axis relative to the frame 1-A1220 or the first outer frame 1-A1100. For example, in this embodiment, the first electromagnetic drive component 1-A1230 can be a drive coil surrounding the accommodating space 1-A1211 of the lens support 1-A1210, and the second electromagnetic drive component 1-A1240 can include at least one magnet. When current flows into the driving coil (first electromagnetic driving component 1-A1230), an electromagnetic effect will be generated between the driving coil and the magnet, thereby driving the lens holder 1-A1210 and the first optical component 1-AS arranged thereon to move along the Z-axis direction relative to the frame 1-A1220, and then move along the Z-axis direction relative to the photosensitive component 1-A1500 to achieve the purpose of autofocus.
[0255] In some embodiments, the first electromagnetic drive component 1-A1230 may be a magnet, and the second electromagnetic drive component 1-A1240 may be a drive coil.
[0256] The first elastic component 1-A1250 and the second elastic component 1-A1260 are respectively disposed on opposite sides of the lens support 1-A1210 / frame 1-A1220, such that the lens support 1-A1210 / frame 1-A1220 is positioned between the first elastic component 1-A1250 and the second elastic component 1-A1260. The inner ring section 1-A1251 of the first elastic component 1-A1250 is connected to the lens support 1-A1210, and the outer ring section 1-A1252 of the first elastic component 1-A1250 is connected to the aforementioned frame 1-A1220. Similarly, the inner ring section 1-A1261 of the second elastic component 1-A1260 is connected to the lens support 1-A1210, and the outer ring section 1-A1262 of the second elastic component 1-A1260 is connected to the frame 1-A1220. In this way, the lens holder 1-A1210 can be suspended in the receiving portion 1-A1221 of the frame 1-A1220 through the aforementioned first elastic component 1-A1250 and the second elastic component 1-A1260, and its movement range in the Z-axis direction can also be limited by the first and second elastic components 1-A1250 and 1-A1260.
[0257] Please continue reading Figure 3 , the aforementioned coil plate 1-A1270 is set on the base 1-A1400. Similarly, when current flows through the coil plate 1-A1270, an electromagnetic effect will be generated between the coil plate 1-A1270 and the aforementioned second electromagnetic drive component 1-A1240 (or the first electromagnetic drive component 1-A1230), causing the lens support seat 1-A1210 and the frame 1-A1220 to move relative to the coil plate 1-A1270 along the X-axis direction and / or the Y-axis direction, thereby driving the first optical component 1-AS to move relative to the photosensitive component 1-A1500 along the X-axis direction and / or the Y-axis direction to achieve the purpose of shake compensation.
[0258] In this embodiment, the first drive component 1-A1200 includes four suspension wires 1-A1280, which are respectively arranged at the four corners of the coil plate 1-A1270 and connect the aforementioned coil plate 1-A1270, the base 1-A1400 and the first elastic component 1-A1250. When the lens support 1-A1210 and the first optical component 1-AS move along the X-axis direction and / or the Y-axis direction, these suspension wires 1-A1280 can limit their movement range. In addition, since the suspension wires 1-A1280 contain metal materials (such as copper or its alloys, etc.), they can also be used as conductors. For example, current can flow into the first electromagnetic drive component 1-A1230 through the base 1-A1400 and the suspension wires 1-A1280.
[0259] A circuit component 1-A1420 is disposed within the base 1-A1400, and the aforementioned position detector 1-A1290 is disposed on the circuit component 1-A1420 to determine the positions of the lens support 1-A1210 and the first optical component 1-AS in the X-axis direction and the Y-axis direction by detecting the displacement of the second electromagnetic drive component 1-A1240. For example, the aforementioned position detector 1-A1290 can be a Hall effect sensor (Hall Sensor), a magnetoresistance effect sensor (Magnetoresistance Effect Sensor, MR Sensor), a giant magnetoresistance effect sensor (GMR Sensor), a tunneling magnetoresistance effect sensor (TMRSensor), or a fluxgate sensor.
[0260] In addition, the first optical component 1-AS may define an optical axis 1-AO, and the position sensing component may also be used to sense the distance moved by the first optical component 1-AS along the optical axis 1-AO.
[0261] Please refer to Figure 4 , Figure 4 1-B is an exploded view of a second lens drive mechanism 1-B100 according to an embodiment of the present disclosure. The second outer frame 1-B110 of the second lens drive mechanism 1-B100 has a hollow structure and has an opening corresponding to the optical component (second optical component 1-BS). In other words, the optical axis 1-BO of the second optical component 1-BS passes through the opening of the second outer frame 1-B110, allowing light to enter the second lens drive mechanism 1-B100 via the optical axis 1-BO.
[0262] Depend on Figure 4 As can be seen, the second lens driving mechanism 1-B100 mainly includes a second outer frame 1-B110, a base 1-B120, a supporting seat 1-B130, a second driving component 1-B140, a frame 1-B150, a first elastic component 1-B161, a second elastic component 1-B162, and a shape memory alloy driving member 1-B170. The second outer frame 1-B110 and the base 1-B120 can be connected to each other and combined into a hollow box body, whereby the supporting seat 1-B130, the second driving component 1-B140, the frame 1-B150, the first elastic component 1-B161, and the second elastic component 1-B162 can be surrounded by the second outer frame 1-B110 and accommodated in this box body.
[0263] The support base 1-B130 has a hollow structure and supports an optical component with an optical axis 1-BO (such as Figure 2 The second optical component 1-BS shown in FIG. 1 is a diagram illustrating a second optical component 1-BS shown in FIG. 1 . The aforementioned frame 1-B150 is disposed on the base 1-B120 and is fixed to the second outer frame 1-B110. In addition, the supporting seat 1-B130 is movably connected to the frame 1-B150 and the base 1-B120. More specifically, the supporting seat 1-B130 can be connected to the frame 1-B150 and the base 1-B120 respectively through a first elastic component 1-B161 and a second elastic component 1-B162 made of metal, so as to movably suspend the supporting seat 1-B130 between the frame 1-B150 and the base 1-B120.
[0264] The second driving component 1-B140 includes at least one first driving coil (driving coil 1-B141), a first driving magnetic component 1-B1421, and a second driving magnetic component 1-B1422, wherein the driving coil 1-B141 is arranged on the supporting seat 1-B130, and the first driving magnetic component 1-B1421 and the second driving magnetic component 1-B1422 can be arranged on the frame 1-B150. When a current is applied to the driving coil 1-B141, an electromagnetic driving force (electromagnetic driving force) can be generated through the aforementioned driving coil 1-B141 and the aforementioned first driving magnetic component 1-B1421 and the second driving magnetic component 1-B1422 to drive the supporting seat 1-B130 and the optical component it carries (such as the second optical component 1-BS) to move along the Z axis (optical axis 1-BO) relative to the base 1-B120 or the second outer frame 1-B110 to perform the autofocus (AF) function. In addition, the second drive component 1-B140 includes a shape memory alloy drive member 1-B170, which is disposed below the base 1-B120 and can drive the support seat 1-B130 and the optical components it carries to move relative to the base 1-B120 in a direction perpendicular to the optical axis 1-BO (XY plane), thereby performing the optical image stabilization (OIS) function. Regarding the actuation method of the shape memory alloy drive member 1-B170, the following will be combined with Figure 5 Provide further explanation.
[0265] Figure 5 A top view of a shape memory alloy driving member 1-B170 according to an embodiment of the present disclosure is shown. Figure 5As shown, the shape memory alloy driving component 1-B170 includes a metal base 1-B171, a metal wire 1-B172 and an insulating layer 1-B173. In this embodiment, the metal base 1-B171 has a quadrilateral structure, and the metal wire 1-B172 is arranged at the four edges of the metal base 1-B171, and is connected to the metal base 1-B171 via the insulating layer 1-B173 at each corner of the metal base 1-B171. The metal wire 1-B172 is made of shape memory alloy (Shape Memory Alloys; SMA), so the metal wire 1-B172 can have a certain plasticity, so each metal wire 1-B172 can independently deform in the horizontal direction (X axis or Y axis) according to the electrical signal. In this way, the supporting seat 1-B130 (see Figure 4 ) on the XY plane, thereby performing the optical image stabilization (OIS) function.
[0266] Please refer to Figure 2 and Figure 6 , Figure 6 FIG. 1 is a schematic diagram of the arrangement of the first lens driving mechanism 1-A1000 and the second lens driving mechanism 1-B100 according to an embodiment of the present disclosure. Figure 2 as well as Figure 6 As shown, the first lens driving mechanism 1-A1000 and the second lens driving mechanism 1-B100 are arranged along a first direction (for example, the X-axis direction), and the first driving magnetic component 1-B1421 has a long strip structure extending along the first direction.
[0267] It is noteworthy that, along the X-axis, no magnetic components of the second lens drive mechanism 1-B100 are located between the first optical assembly 1-AS and the second optical assembly 1-BS. For example, the first drive magnetic component 1-B1421 is not disposed between the first optical assembly 1-AS and the second optical assembly 1-BS. This arrangement of magnetic components reduces electromagnetic interference and shortens the distance between the first optical assembly 1-AS and the second optical assembly 1-BS, thereby improving image quality.
[0268] Please refer to Figure 7 , Figure 7 This is a perspective view of an optical camera system 1-3 according to one embodiment of the present disclosure. In this embodiment, the first lens driving mechanism 1-A1000 and the second lens driving mechanism 1-B100 are arranged in opposite directions. Light enters the first lens driving mechanism 1-A1000 along the -Z axis, while light enters the second lens driving mechanism 1-B100 from the Z axis.
[0269] Based on the above configuration, the optical camera systems 1-3 can capture images at different angles, and the arrangement of their magnetic components is similar. Figure 5 , thus reducing electromagnetic interference and significantly reducing the occupied volume to achieve the purpose of miniaturization.
[0270] Please refer to Figure 8 , Figure 8 It is a stereoscopic diagram of an optical camera system 1-4 according to an embodiment of the present disclosure. In this embodiment, the optical camera system 1-4 includes a first lens driving mechanism 1-A1000, a second lens driving mechanism 1-B100 and a third lens driving mechanism 1-C100, which are arranged along the first direction (X-axis direction). The third lens driving mechanism 1-C100 has the same structure as the second lens driving mechanism 1-B100 and is configured to carry a third optical component 1-CS. The third lens driving mechanism 1-C100 also has a third outer frame 1-C110 and a third driving component (for example, including a first driving magnetic component 1-C1421 and a second driving magnetic component 1-C1422). The remaining structures and actuation methods are the same as those of the second lens driving mechanism 1-B100 and will not be repeated here.
[0271] like Figure 8 As shown, the arrangement of the magnetic components in the optical camera system 1-4 is similar to Figure 6 , thus also reducing electromagnetic interference.
[0272] Please refer to Figure 9 , Figure 9 FIG2 is a schematic diagram of an optical camera system 1-4 from another perspective according to an embodiment of the present disclosure. In this embodiment, a circuit pin 1-B180 of the second lens driving mechanism 1-B100, a circuit pin 1-C180 of the third lens driving mechanism 1-C100, and a circuit pin (circuit component 1-A1420) of the first lens driving mechanism 1-A1000 are all disposed on the same side of the optical camera system 1-4.
[0273] Since adjacent sides of the lens drive mechanisms are not provided with circuit pins for electrical connection to the outside world, the distance between the drive mechanisms along the X-axis direction can be shortened. Moreover, since the circuit pins are parallel to the arrangement direction of the lens drive mechanisms (the X-axis direction), processing efficiency can be improved, thereby reducing manufacturing costs.
[0274] Please refer to Figure 10 , Figure 10FIG1 is a perspective schematic diagram of an optical camera system 1-5 according to another embodiment of the present disclosure. Optical camera system 1-5 is similar to optical camera system 1-4, except that one of the lens drive mechanisms of optical camera system 1-5 is a periscope lens drive mechanism (a fourth lens drive mechanism 1-D1000).
[0275] In this embodiment, the first optical component 1-AS of the first lens driving mechanism 1-A1000 is a wide-angle lens with one focal length (first focal length), the second optical component 1-BS of the second lens driving mechanism 1-B100 is a lens with two focal lengths, and a fourth optical component (lens 1-D1120) of the fourth lens driving mechanism 1-D1000 is a wide-angle lens with three times the focal length (second focal length) or more, so that the optical camera system 1-5 can achieve three-stage optical zoom.
[0276] Please refer to Figure 11 , Figure 11 According to an embodiment of the present disclosure Figure 10 The cross-sectional view of (1-A)-(1-A'). Figure 11 As shown, the fourth lens driving mechanism 1-D1000 includes a lens unit 1-D1100, a reflection unit 1-D1200, and a photosensitive component 1-D1300. External light (e.g., light 1-L) enters the fourth lens driving mechanism 1-D1000 through the first light inlet 1-D1001 and is first reflected by the reflection unit 1-D1200, then passes through the lens unit 1-D1100 and is received by the photosensitive component 1-D1300.
[0277] The following describes the specific structures of the lens unit 1-D1100 and the reflection unit 1-D1200 in this embodiment. Figure 11 As shown, the lens unit 1-D1100 mainly includes a lens driving module 1-D1110 and a lens 1-D1120, wherein the lens driving module 1-D1110 is used to drive the aforementioned lens 1-D1120 to move relative to the photosensitive component 1-D1300. For example, the aforementioned lens driving module 1-D1110 may include a lens support 1-D1111, a frame 1-D1112, two springs 1-D1113, at least one coil 1-D1114, and at least one magnetic component 1-D1115.
[0278] The aforementioned lens 1-D1120 is fixed in the lens support seat 1-D1111. Two springs 1-D1113 connect the lens support seat 1-D1111 and the frame 1-D1112, and are respectively located on opposite sides of the lens support seat 1-D1111, so that the lens support seat 1-D1111 can be movably suspended in the frame 1-D1112. The coil 1-D1114 and the magnetic component 1-D1115 are respectively arranged on the lens support seat 1-D1111 and the frame 1-D1112, and correspond to each other. When current flows into the coil 1-D1114, an electromagnetic effect is generated between the coil 1-D1114 and the magnetic component 1-D1115, and the lens support seat 1-D1111 and the lens 1-D1120 arranged on the lens support seat 1-D1111 can be driven to move relative to the photosensitive component 1-D1300, for example, along the X-axis direction or the Y-axis direction. In addition, the lens unit 1-D1100 may further include a position sensing component 1-D1116, configured to sense the movement of the lens support 1-D1111 relative to the frame 1-D1112.
[0279] The reflection unit 1-D1200 mainly includes an optical component 1-D1210, an optical component support seat 1-D1220, a frame 1-D1230, at least a first pivot 1-D1250, a first driving module 1-D1260, and a position detector 1-D1201.
[0280] The optical component support seat 1-D1220 can be pivotally connected to the frame 1-D1230 via the first pivot 1-D1250. Since the optical component 1-D1210 is disposed on the optical component support seat 1-D1220, when the optical component support seat 1-D1220 rotates relative to the frame 1-D1230, the optical component 1-D1210 disposed thereon can also rotate relative to the frame 1-D1230 at the same time. The aforementioned optical component 1-D1210 can be, for example, a prism or a reflector.
[0281] The first driving module 1-D1260 may include a first electromagnetic driving component 1-D1261 and a second electromagnetic driving component 1-D1262, which are respectively arranged on the frame 1-D1230 and the optical component support seat 1-D1220, and the positions of the two correspond to each other.
[0282] For example, the first electromagnetic drive component 1-D1261 may include a drive coil, and the second electromagnetic drive component 1-D1262 may include a magnet. When current is passed through the drive coil (first electromagnetic drive component 1-D1261), an electromagnetic effect will be generated between the drive coil and the magnet, thereby driving the optical component support 1-D1220 and the optical component 1-D1210 to rotate relative to the frame 1-D1230 around the first pivot 1-D1250 (extending along the Y-axis direction), thereby adjusting the position of the external light 1-L reaching the photosensitive component 1-D1300.
[0283] It is worth noting that the direction of the incident light entering the fourth optical component (lens 1-D1120) (for example, along the X-axis direction) is different from the direction of the incident light entering the first optical component of the first lens driving mechanism 1-A1000 (for example, along the Z-axis direction).
[0284] The position detector 1-D1201 can be disposed on the frame 1-D1230 and correspond to the second electromagnetic drive component 1-D1262, so as to obtain the rotation angle of the optical component 1-D1210 by detecting the position of the second electromagnetic drive component 1-D1262. The position detector 1-D1201 can be, for example, a Hall effect sensor, a magnetoresistive effect sensor, a giant magnetoresistive effect sensor, a tunneling magnetoresistive effect sensor, or a magnetic flux sensor.
[0285] In some embodiments, the first electromagnetic drive component 1-D1261 may include a magnet, and the second electromagnetic drive component 1-D1262 may include a drive coil. In these embodiments, the position detector 1-D1201 may be disposed on the optical component support 1-D1220 and correspond to the first electromagnetic drive component 1-D1261.
[0286] In addition, it is worth noting that the arrangement of the lens drive mechanism in the optical camera system 1-5 can also achieve the effect of reducing electromagnetic interference.
[0287] Please refer to Figure 12 , Figure 12 Schematic diagram of an optical camera system 1-6 according to an embodiment of the present disclosure. In order to improve space utilization, in this embodiment, the lens drive mechanisms are arranged in an L-shaped manner. Figure 12 As shown, the magnetic component (first driving magnetic component 1-B1421 or second driving magnetic component 1-B1422) is not arranged on the side adjacent to the second lens driving mechanism 1-B100 and the first lens driving mechanism 1-A1000, so the problem of electromagnetic interference can also be reduced.
[0288] In addition, in other embodiments, one of the second lens driving mechanisms 1-B100 in the optical camera system 1-6 can also be replaced by the fourth lens driving mechanism 1-D1000 to obtain different shooting effects.
[0289] Please refer to Figure 13 , Figure 13 FIG. 1 is a bottom schematic diagram of an optical camera system 1-6 according to an embodiment of the present disclosure. Figure 13 As shown, the circuit pins (circuit component 1-A1420) of the first lens driving mechanism 1-A1000 are arranged on two adjacent sides of the first outer frame 1-A1100 to facilitate the operator to solder the optical camera system 1-6 to the main circuit board of the electronic device 1-0. In addition, as shown Figure 13 As shown, the circuit pins are not arranged on two adjacent sides of the two lens driving mechanisms.
[0290] Please refer to Figure 14 , Figure 14 FIG1 is a schematic diagram of an optical camera system 1-7 according to an embodiment of the present disclosure. In this embodiment, the optical camera system 1-7 includes two first lens drive mechanisms 1-A1000 and two second lens drive mechanisms 1-B100. Furthermore, the configuration of the driving magnetic components in this embodiment can also reduce electromagnetic interference issues.
[0291] The multiple optical camera systems provided in the present disclosure can perform image processing through the processing circuit 1-X to obtain better shooting quality. For example, when the electronic device 1-0 is configured with an optical camera system having three lens driving mechanisms (such as the optical camera system 1-4), the first lens driving mechanism 1-A1000, the second lens driving mechanism 1-B100 and the third lens driving mechanism 1-C100 can respectively obtain a first image, a second image and a third image. When the light source is insufficient, the image taken by a single lens driving mechanism may not be clear enough, then the processing circuit 1-X can synthesize the first, second and third images, and finally obtain a clear synthesized image. This image processing method can shorten the exposure time of the optical camera system and reduce the probability of interference (external influences such as hand shaking, instantaneous strong light, etc.).
[0292] In another embodiment, when the first lens driving mechanism 1-A1000, the second lens driving mechanism 1-B100, and the third lens driving mechanism 1-C100 are all photographing the same object or scene, the processing circuit 1-X can be configured to compare the first image, the second image, and the third image. If a pattern is included in the first image but not in the second and third images, the processing circuit 1-X determines that the pattern is noise and removes the pattern from the composite image.
[0293] In another embodiment, the lens drive mechanism can capture a monochrome image. For example, the first image, the second image, and the third image respectively contain red light information, blue light information, and green light information. The processing circuit 1-X then synthesizes the first, second, and third images into a color image.
[0294] In another embodiment, at least one of the first, second, and third images is a color image, and at least one of the first, second, and third images is a black and white image. The processing circuit 1-X then synthesizes the first, second, and third images into a color image. This synthesized color image can be clearer than a color image captured by a single lens drive mechanism.
[0295] Please refer to Figure 15 , Figure 15 FIG1 is a side schematic diagram of an electronic device 1-0 according to another embodiment of the present disclosure. In this embodiment, the optical camera system 1-4 may further include an infrared light source 1-R configured to emit infrared light. The infrared light source 1-R may emit diffuse light 1-RS, which serves as a light source for capturing images. Furthermore, the infrared light source 1-R may also include an adjustment component 1-RJ that causes the infrared light source 1-R to emit a parallel light beam 1-RP for depth sensing.
[0296] In this embodiment, at least one of the first image, the second image, and the third image captured by the optical camera system 1-4 may include infrared light information. In the case of insufficient light source, the infrared light image may be synthesized to make the synthesized image clearer.
[0297] In addition, infrared light can also be used for depth sensing, and the processing circuit 1-X then processes the synthetic image according to software calculations to enhance the image effect.
[0298] Please refer to Figure 16 , Figure 16 1 - GA, a second image 1 - GB, and a third image 1 - GC according to an embodiment of the present disclosure. Figure 16 The left-center diagram shows a first image 1-GA, the middle diagram shows a second image 1-GB, and the right-center diagram shows a third image 1-GC. A first lens driving mechanism 1-A1000 having a focal length of one times (a first focal length) photographs an object 1-OJ to produce the first image 1-GA, a second lens driving mechanism 1-B100 having a focal length of two times (a second focal length) photographs the object 1-OJ to produce the second image 1-GB, and a fourth lens driving mechanism 1-D1000 having a focal length of more than three times (a third focal length) photographs the object 1-OJ to produce the third image 1-GC.
[0299] The third image 1-GC corresponds to the second image 1-GB or a region 1-RC in the first image 1-GA, while the second image 1-GB corresponds to a region 1-RB in the first image 1-GA. The processing circuit 1-X can synthesize the three images based on the third image 1-GC. For example, the processing circuit 1-X synthesizes the region 1-RC in the first image 1-GA, the region 1-RC in the second image 1-GB, and the third image 1-GC. This increases local detail in the synthesized image.
[0300] In addition, in some embodiments of the present disclosure, since there is a distance between the two lens driving mechanisms in the optical camera system, the two captured images have parallax, so the processing circuit 1-X can synthesize the two images into a 3D stereoscopic image.
[0301] The present disclosure provides an optical camera system disposed within an electronic device. The optical camera system comprises multiple lens drive mechanisms that can be arranged in various configurations to achieve different photographic effects. In one embodiment, a first lens drive mechanism and a second lens drive mechanism are arranged along a first direction, and no magnetic components of the second lens drive mechanism are located between the first and second optical components, thereby avoiding electromagnetic interference.
[0302] In addition, in another embodiment, the multiple lens driving mechanisms may have different focal lengths, and the same object may be photographed to obtain multiple images, which are then synthesized by a processing circuit to obtain a clearer synthesized image.
[0303] Second set of embodiments
[0304] Please refer to Figures 17 to 19 , Figure 17 is a three-dimensional schematic diagram of an optical component driving mechanism 2-100 according to an embodiment of the present disclosure, Figure 18 According to this disclosure Figure 17 An exploded view of the optical component driving mechanism 2-100 of an embodiment, and Figure 19 Indicates along Figure 17 A cross-sectional view taken along line (2-A)-(2-A') in FIG. The optical component driving mechanism 2-100 may be an optical camera system configured to carry and drive an optical component 2-LS, and the optical component driving mechanism 2-100 may be installed in various electronic devices or portable electronic devices, such as a smartphone or tablet computer, to allow the user to perform image capture functions. In this embodiment, the optical component driving mechanism 2-100 may be a voice coil motor (VCM) having an autofocus (AF) function, but the present disclosure is not limited thereto. In other embodiments, the optical component driving mechanism 2-100 may also have autofocus (AF) and optical image stabilization (OIS) functions.
[0305] like Figures 17 to 19 As shown, in the present embodiment, the optical component driving mechanism 2-100 mainly includes a fixed component (which may include a housing 2-102, a frame 2-104, and a base 2-112), a first elastic component 2-106, a movable component (including a supporting seat 2-108), a driving component (which may include a first magnet 2-M11, a second magnet 2-M12, and a driving coil 2-DCL), a second elastic component 2-110, a circuit unit 2-114, a magnetic force sensing unit 2-116, and a circuit component 2-118. The supporting seat 2-108 is movable relative to the fixed component, and the supporting seat 2-108 is used to support the optical component 2-LS. It should be noted that in other embodiments, the components in the fixed component can also be adjusted to be movable (that is, included in the movable component) according to actual needs. For example, the frame 2-104 can be designed to be movable in other embodiments.
[0306] In this embodiment, if Figure 19 As shown, the optical component 2-LS may be a lens, and the optical component 2-LS defines an optical axis 2-0. Furthermore, the optical component 2-LS may have a body 2-LSB and a plurality of lenses 2-LSP, and the lenses 2-LSP are fixed in the body 2-LSB.
[0307] like Figure 18 As shown, the aforementioned housing 2-102 has a hollow structure and has a housing opening 2-1021 formed therein. A base opening 2-1121 is formed on the base 2-112. The center of the housing opening 2-1021 corresponds to the optical axis 2-O of the plurality of lenses 2-LSP carried by the body 2-LSB, and the base opening 2-1121 corresponds to the image sensing component (not shown) disposed below the base 2-112. External light can enter the housing 2-102 through the housing opening 2-1021 and, after passing through the optical component 2-LS and the base opening 2-1121, be received by the aforementioned image sensing component (not shown) to generate a digital image signal.
[0308] Furthermore, the housing 2-102 may have a receiving space 2-1023 for accommodating the aforementioned frame 2-104, the supporting base 2-108, the first elastic component 2-106, the first magnet 2-M11, the second magnet 2-M12, the drive coil 2-DCL and the circuit unit 2-114 and other components. In this embodiment, the circuit unit 2-114 may be a circuit board, and the drive component is electrically connected to the circuit unit 2-114 and can drive the supporting base 2-108 to move relative to the fixed component, for example, relative to the base 2-112. The magnetic sensing unit 2-116 is disposed on the circuit unit 2-114 and is configured to sense a magnetic component (not shown in the figure) disposed on the supporting base 2-108, thereby obtaining the position of the supporting base 2-108 relative to the base 2-112.
[0309] In this embodiment, the optical element driving mechanism 2-100 includes two magnets, and the first magnet 2-M11 and the second magnet 2-M12 may be in the shape of elongated bars. However, their number and shape are not limited thereto and, for example, may have different shapes in other embodiments. Furthermore, the first magnet 2-M11 or the second magnet 2-M12 may be a multi-pole magnet.
[0310] like Figure 18 and Figure 19 As shown, the frame 2-104 is fixedly arranged on the inner wall surface of the shell 2-102, and the first magnet 2-M11 and the second magnet 2-M12 can also be fixedly arranged on the frame 2-104 and the inner wall surface of the shell 2-102. Figure 18 and Figure 19 As shown, in this embodiment, the drive coil 2-DCL can be a wound coil that is disposed around the support base 2-108, and the drive coil 2-DCL corresponds to the first magnet 2-M11 and the second magnet 2-M12. When the drive coil 2-DCL is energized, it can generate an electromagnetic driving force with the first magnet 2-M11 and the second magnet 2-M12 to drive the support base 2-108 and the optical component 2-LS to move relative to the base 2-112 along the direction of the optical axis 2-O (Z-axis direction).
[0311] Furthermore, if Figure 18 As shown, the base 2-112 is formed with four protrusions 2-1122 and a receiving groove 2-1123. The protrusions 2-1122 extend along the direction of the optical axis 2-O. In this embodiment, the first elastic component 2-106 is disposed between the housing 2-102 (a part of the fixed component) and the frame 2-104, and the outer portion of the first elastic component 2-106 is fixed to the frame 2-104, so that the supporting seat 2-108 is movably connected to the frame 2-104 through the first elastic component 2-106.
[0312] Similarly, the outer portion of the second elastic component 2-110 is fixed to the receiving groove 2-1123. In addition, the inner portion of the first elastic component 2-106 and the second elastic component 2-110 are respectively connected to the upper and lower sides of the supporting seat 2-108, so that the supporting seat 2-108 can be set in the frame 2-104 in a suspended manner (such as Figure 19 As shown). Therefore, the drive assembly can drive the support seat 2-108 to move relative to the frame 2-104.
[0313] like Figure 18 As shown, the circuit component 2-118 is disposed within the base 2-112. For example, the base 2-112 is made of a plastic material, and the circuit component 2-118 is formed within the base 2-112 in the form of a molded interconnect device (MID). In one embodiment, the circuit unit 2-114 can be electrically connected to the second elastic element 2-110 via the circuit component 2-118.
[0314] like Figure 19 As shown, when viewed in a direction perpendicular to the optical axis 2-O (e.g., along the X-axis), the support base 2-108 partially overlaps the fixed assembly. Specifically, the housing 2-102 in the fixed assembly has a top wall 2-102T and a plurality of side walls 2-102S extending from the top wall 2-102T in the direction of the optical axis 2-O, and when viewed in a direction perpendicular to the optical axis 2-O, the top wall 2-102T partially overlaps the support base 2-108.
[0315] In this embodiment, the support seat 2-108 has an extension portion 2-108E that extends along the direction of the optical axis 2-O and when viewed in a direction perpendicular to the optical axis 2-O (for example Figure 19 (as viewed along the X-axis direction), the top wall 2-102T partially overlaps the extension portion 2-108E. That is, the extension portion 2-108E protrudes from the top wall 2-102T along the Z-axis direction.
[0316] Please refer to Figure 20 , Figure 20 Schematic diagram of the base 2-112 and the supporting seat 2-108 according to an embodiment of the present disclosure. Figure 20 As shown, when viewed in a direction perpendicular to the optical axis 2-O, for example, along the Y-axis direction, the boss 2-1122 of the base 2-112 partially overlaps with the support seat 2-108.
[0317] Furthermore, if Figure 19 as well as Figure 20As shown, the support base 2-108 may further include a stop member 2-108P, such as a bump. The stop member 2-108P faces the top wall 2-102T of the housing 2-102 and extends in the direction of the optical axis 2-O. The stop member 2-108P is configured to limit the range of movement of the support base 2-108 along the Z-axis direction.
[0318] Please refer to Figure 21 , Figure 21 1 is an enlarged schematic diagram of a support seat 2-108 and an optical component 2-LS according to an embodiment of the present disclosure. The extension portion 2-108E has an inner wall surface 2-1081, which faces the optical component 2-LS, and the body 2-LSB of the optical component 2-LS has an outer wall surface 2-LSS, which faces the inner wall surface 2-1081. Furthermore, the optical component driving mechanism 2-100 may further include an adhesive material 2-AD, such as glue, disposed between the outer wall surface 2-LSS and the inner wall surface 2-1081 to secure the optical component 2-LS to the support seat 2-108 (lens).
[0319] Please refer to Figure 22 , Figure 22 1 is an enlarged schematic diagram of a support seat 2-108 and an optical component 2-LS according to another embodiment of the present disclosure. In this embodiment, the inner wall surface 2-1081 may have a hook portion 2-1082, and the outer wall surface 2-LSS may have a fitting portion 2-LSG. The fitting portion 2-LSG is configured to couple to the hook portion 2-1082 to prevent the optical component 2-LS from being separated from the support seat 2-108. In one embodiment, the hook portion 2-1082 may be an internal thread, and the fitting portion 2-LSG may be an external thread, but is not limited thereto.
[0320] Furthermore, in other embodiments, the hook portion 2-1082 and the engaging portion 2-LSG may not contact each other, but instead an adhesive material 2-AD may be disposed between the hook portion 2-1082 and the engaging portion 2-LSG to secure the optical component 2-LS to the support base 2-108. Based on this structural configuration, the bonding area between the adhesive material 2-AD and the inner wall surface 2-1081 and the outer wall surface 2-LSS can be increased, thereby improving the bonding strength.
[0321] Please refer to Figure 23 , Figure 23This is an enlarged schematic diagram of a support base 2-108 and an optical component 2-LS according to another embodiment of the present disclosure. In this embodiment, a screw thread structure 2-1083 may be formed on a portion of the inner wall surface 2-1081, and an adhesive material 2-AD is disposed between the inner wall surface 2-1081 and the outer wall surface 2-LSS to secure the optical component 2-LS to the support base 2-108. Based on this structural configuration, the bonding area between the adhesive material 2-AD and the inner wall surface 2-1081 and the outer wall surface 2-LSS can be increased, thereby improving the bonding strength.
[0322] It is worth noting that when viewed along the direction of the optical axis 2-O (Z-axis direction), the support seat 2-108 does not overlap with the optical component 2-LS.
[0323] Please refer to Figure 24 , Figure 24 2 is a perspective schematic diagram of an optical component driving mechanism 2-200 according to another embodiment of the present disclosure. In this embodiment, the supporting seat 2-108' may include four plate-shaped extensions 2-108E, which are respectively arranged corresponding to the four corners of the housing 2-102. Figure 24 As shown, a guide slope 2-108C can be formed at one end of each extension portion 2-108E, which is configured to guide the optical component 2-LS (lens) when it is installed on the supporting seat 2-108, so as to improve the convenience during assembly.
[0324] It should be noted that the number of extensions 2-108E is not limited to this. In other embodiments, the support seat 2-108 may only include two extensions 2-108E, corresponding to the diagonal corners of the fixing component.
[0325] Please refer to Figure 25 , Figure 25 FIG. 2 is a top view of an optical component driving mechanism 2-200 according to another embodiment of the present disclosure. Figure 25 As shown, when viewed along the direction of the optical axis 2-O, a distance 2-D1 between two relative extensions 2-108E is slightly smaller than a diameter 2-D2 of the housing opening 2-1021 along a first direction 2-A1 (for example, the Y-axis direction), and the first direction 2-A1 is substantially perpendicular to one of the side walls 2-102S.
[0326] Furthermore, the top wall 2-102T further has four notches 2-1024 that communicate with the housing opening 2-1021, and the extensions 2-108E are respectively disposed within the notches 2-1024. Based on this structural design, the optical component drive mechanism 2-200 can accommodate a larger lens while maintaining the overall structural strength of the optical component drive mechanism 2-200.
[0327] The present disclosure provides an optical component driving mechanism having a supporting seat 2-108 configured to support an optical component 2-LS (lens). One or more extensions 2-108E may be formed on the supporting seat 2-108 to increase the contact area between the glue and the supporting seat 2-108 and between the glue and the optical component 2-LS, thereby improving the strength of the bond. Therefore, when a heavier lens (such as a glass lens) is set in the optical component 2-LS, the supporting seat 2-108 can still stably support the optical component 2-LS, so that when the optical component driving mechanism is impacted, the optical component 2-LS will not fall off the supporting seat 2-108.
[0328] The third set of embodiments
[0329] First, please refer to Figures 26-29 ,in Figure 26 An exploded view of a drive mechanism 3-1 according to an embodiment of the present disclosure is shown. Figure 27 express Figure 26 Schematic diagram of the combined driving mechanism 3-1, Figure 28 express Figure 27 A three-dimensional diagram of the driving mechanism 3-1 after removing the housing 3-10 and the first elastic component 3-30, Figure 29 It means Figure 27 A three-dimensional view of the driving mechanism 3-1 after removing the shell 3-10, the first elastic component 3-30 and the frame 3-60.
[0330] like Figures 26-29 As shown, the driving mechanism 3-1 of this embodiment is, for example, a voice coil motor (VCM), which can be installed inside a mobile phone or other portable electronic device to drive an optical component (such as an optical lens) to move, thereby achieving functions such as auto focusing (AF) or optical image stabilization (OIS).
[0331] The aforementioned driving mechanism 3-1 has a rectangular structure, which mainly includes a shell 3-10, a base 3-20, at least one first elastic component 3-30, at least one second elastic component 3-40, a carrier 3-50, a frame 3-60, a circuit board 3-70 and at least one magnetic component 3-M. The aforementioned frame 3-60 is fixed to the inner surface of the shell 3-10, and the aforementioned circuit board 3-70 is fixed on the frame 3-60 and passes through a slot 3-22 of the base 3-20 to protrude from the bottom side of the base 3-20.
[0332] The aforementioned carrier 3-50 can be used to carry an optical component (such as an optical lens) and can constitute a movable module of the driving mechanism 3-1, and the aforementioned shell 3-10, base 3-20, frame 3-60 and circuit board 3-70 are fixed to each other to constitute a fixed module of the driving mechanism 3-1; in the present embodiment, the first elastic component 3-30 connects the carrier 3-50 and the frame 3-60, and the second elastic component 3-40 connects the carrier 3-50 and the base 3-20, so that the carrier 3-50 and the optical component arranged therein can be suspended inside the shell 3-10 and can move along the Z-axis direction relative to the base 3-20, the frame 3-60 and the circuit board 3-70.
[0333] It should be understood that at least one magnetic component 3-M fixed on the frame 3-60 and the coil 3-C arranged around the carrier 3-50 can constitute a driving component. When an electric current is transmitted to the aforementioned coil 3-C via the circuit board 3-70, the aforementioned magnetic component 3-M and the coil 3-C can generate an electromagnetic driving force to drive the carrier 3-50 and the optical component arranged therein to move along the Z-axis direction relative to the base 3-20, the frame 3-60 and the circuit board 3-70, thereby achieving the function of autofocus (AF).
[0334] Alternatively, rather than using the aforementioned coil 3-C, two oval coils (not shown) may be disposed on opposite sides of the rectangular carrier 3-50 and adjacent to the aforementioned magnetic assembly 3-M. This similarly generates an electromagnetic driving force between the magnets and the coils to drive the movable module relative to the fixed module. It should be noted that in this case, the circuit board 3-70 is located on the side of the carrier 3-50 where the driving assembly (magnets and coils) is not disposed.
[0335] In addition, in this embodiment, a sensing component 3-82 on the circuit board 3-70 can be used to sense a sensed object 3-88 on the carrier 3-50, so as to know the relative movement between the carrier 3-50 and the frame 3-60, thereby enabling closed-loop control of the drive mechanism 3-1 to improve the control accuracy and overall performance of the drive mechanism 3-1.
[0336] like Figure 26As shown, an electronic component 3-86 is further provided on the outer surface 3-74 of the aforementioned circuit board 3-70, wherein the sensing component 3-82 and the electronic component 3-86 can be electrically connected to each other through a plurality of electrical contacts (not shown) on the outer surface 3-74, and the sensing component 3-82, the electronic component 3-86, and the aforementioned sensed object 3-88 can constitute a position sensing component 3-80. For example, the aforementioned sensing component 3-82 can adopt a Hall effect sensor, a magnetoresistive sensor (MR sensor), or a fluxgate sensor to sense the position of the sensed object 3-88 (e.g., a magnet), thereby determining the relative position change between the carrier 3-50 and the frame 3-60 in the Z-axis direction.
[0337] from Figure 26 、 27 As can be seen, the housing 3-10 has a top 3-12, at least one side wall 3-14, and a through hole 3-H1. The through hole 3-H1 extends through the top 3-12 along an optical axis 3-O of the optical assembly, and the optical axis 3-O is parallel to the Z axis. It should be understood that the side wall 3-14 extends from the edge of the top 3-12 along the -Z axis toward the base 3-20 and is interconnected with the base 3-20. In addition, the housing 3-10 further forms an inner circumferential surface 3-141 surrounding the through hole 3-H1 and generally parallel to the Z axis.
[0338] The aforementioned base 3-20 includes a base body 3-21, a long strip of slots 3-22, four protrusions 3-24 and an opening 3-H3, wherein the opening 3-H3 and the slots 3-22 pass through the base body 3-21, and a long axis of the slots 3-22 extends in the Y-axis direction; in addition, the aforementioned protrusions 3-24 are located at the four corners of the base body 3-21 and extend toward the top 3-12 of the shell 3-10.
[0339] like Figures 26-29 As shown, the aforementioned carrier 3-50 has an opening 3-H2, wherein the opening 3-H2 passes through the carrier 3-50 along the Z-axis direction for supporting the aforementioned optical component, and the optical axis 3-O of the optical component passes through the through hole 3-H1 of the housing 3-10, the opening 3-H2 of the carrier 3-50, and the opening 3-H3 of the base 3-20 in sequence. It should be understood that the aforementioned optical component can be used to guide light through the drive mechanism 3-1 to reach an image sensor (not shown) located below the drive mechanism 3-1, thereby forming a digital image. In this embodiment, the drive mechanism 3-1 is provided with two magnetic components 3-M and a coil 3-C. The aforementioned two magnetic components 3-M are fixed to the frame 3-60 and are located on opposite sides of the carrier 3-50. The aforementioned coil 3-C is disposed on the carrier 3-50 and surrounds the carrier 3-50.
[0340] Please also refer to Figures 26-30 ,in Figure 30 Indicates along Figure 27 Partial cross-sectional view of the midline segment (3-Y1)-(3-Y1). As shown in Figures 26 and 30, the frame 3-60 has an inner side surface 3-62, an outer side surface 3-64, a contact surface 3-66 and a bearing surface 3-68 ( Figure 30 ), wherein the aforementioned inner side surface 3-62 and the outer side surface 3-64 are located on opposite sides of the frame 3-60 and are parallel to the Z-axis, and the aforementioned outer side surface 3-64 abuts against the inner circumferential surface 3-141 of the shell 3-10.
[0341] It should be noted that the aforementioned abutting surface 3-66 and the supporting surface 3-68 are oriented toward the base 3-20 and are located between the inner side surface 3-62 and the outer side surface 3-64, wherein the abutting surface 3-66 is closer to the outer side surface 3-64 than the supporting surface 3-68, and the supporting surface 3-68 is closer to the inner side surface 3-62 than the abutting surface 3-66. In this embodiment, the four protrusions 3-24 on the base 3-20 abut against the four corners of the bottom side of the rectangular frame 3-60 after assembly.
[0342] Please also refer to Figures 26-31 ,in Figure 31 Indicates along Figure 27 The cross-sectional view of the midline segment (3-Y2)-(3-Y2). Figures 26-31 As shown, the aforementioned circuit board 3-70 passes through the slot 3-22 of the base 3-20. During assembly, an adhesive (such as glue) can be applied to the aforementioned slot 3-22 to connect the circuit board 3-70 and the base 3-20, wherein the top surface of the circuit board 3-70 can abut against the supporting surface 3-68 of the frame 3-60, thereby improving the positioning accuracy of the circuit board 3-70 and strengthening the overall structural strength of the driving mechanism 3-1, and when observed along the Z-axis direction, the aforementioned frame 3-60 at least partially overlaps with the circuit board 3-70.
[0343] In addition, from Figure 31 It can be seen that the aforementioned circuit board 3-70 has an inner surface 3-72 and an outer surface 3-74, wherein the inner surface 3-72 faces the carrier 3-50, and the outer surface 3-74 faces the inner circumferential surface 3-141 of the shell 3-10; it should be understood that the inner side surface 3-62 of the aforementioned frame 3-60 is closer to the carrier 3-50 than the inner surface 3-72 of the circuit board 3-70.
[0344] Please continue reading Figure 26 、 31In this embodiment, the sensing component 3-82 and the electronic component 3-86 are disposed on the outer surface 3-74 of the circuit board 3-70. A top surface 3-822 of the sensing component 3-82 faces the top 3-12 of the housing 3-10 and abuts against the abutting surface 3-66 of the frame 3-60, thereby achieving a good positioning effect between the sensing component 3-82 and the frame 3-60. For example, the electronic component 3-86 may be a capacitor or a filter component.
[0345] from Figure 30 It can be seen that an outer wall surface 3-821 of the sensing component 3-82 is facing the inner peripheral surface 3-141 of the shell 3-10, and the outer wall surface 3-821 and the outer side surface 3-64 of the frame 3-60 are separated by a distance in the X-axis direction. For example, the sensed object 3-88 can be a magnetic component (such as a magnet), which is fixed on the carrier 3-50 and corresponds to the sensing component 3-82; when observed along the X-axis direction, the sensed object 3-88 and the sensing component 3-82 at least partially overlap. It should be understood that since the sensed object 3-88 moves with the carrier 3-50, the sensing component 3-82 can be used to sense the position change of the sensed object 3-88 to know the position relationship of the carrier 3-50 relative to the fixed module.
[0346] In this embodiment, by disposing the sensing component 3-82 and the electronic component 3-86 on the outer surface 3-74 of the circuit board 3-70, the sensing component 3-82 and the electronic component 3-86 can be effectively prevented from being collided with by the carrier 3-50, thereby ensuring that the sensing component 3-82 or the electronic component 3-86 will not be damaged by collision with other components when the driving mechanism 3-1 is operating, thereby improving the reliability and stability of the driving mechanism 3-1.
[0347] On the other hand, since the inner side surface 3-62 of the frame 3-60 is closer to the carrier 3-50 than the circuit board 3-70, the circuit board 3-70 can be prevented from being damaged by the collision with the carrier 3-50. The outer side surface 3-64 of the frame 3-60 is closer to the side wall 3-14 of the shell 3-10 than the sensing component 3-82, so a gap can be formed between the sensing component 3-82 and the inner peripheral surface 3-141 of the shell 3-10 to ensure that the sensing component 3-82 will not be damaged by the collision with the shell 3-10, thereby greatly improving the structural strength and service life of the driving mechanism 3-1.

During assembly, an adhesive 3-G can be applied in the recess 3-23 to firmly connect the housing 3-10 and the circuit board 3-70 (as shown in FIG. Figures 34-36 shown).

Figures 37-38 Examples and Figures 32-36 The main difference between the embodiment and the embodiment is that the housing 3-10 is further formed with at least one notch portion 3-R. In this embodiment, two notches 3-R are formed on the side wall 3-14 of the housing 3-10 and arranged along the Y-axis direction to respectively accommodate the aforementioned sensing component 3-82 and electronic component 3-86 on the circuit board 3-70.

Figure 39 As shown, during assembly, adhesive 3-G can be applied in the aforementioned notch portion 3-R, wherein the adhesive 3-G will cover the aforementioned sensing component 3-82 and electronic component 3-86 to ensure that the sensing component 3-82 and electronic component 3-86 will not be directly impacted by external objects, while also enhancing the overall structural strength of the circuit board 3-70 and safety during operation.

Figure 41 Indicates the use of Figure 40 Schematic diagram of the shielding portion 3-143 of the shell 3-10 shielding the sensing component 3-82 on the circuit board 3-70.
[0355] Figure 40 、 41 Examples and Figures 37-39 The main difference between the embodiment of the present invention and the embodiment of the present invention lies in that the side wall 3-14 of the housing 3-10 is formed with at least one thin shielding portion 3-143 for shielding the sensing component 3-82 and / or the electronic component 3-86, and the shielding portion 3-143 is separated from the sensing component 3-82 and / or the electronic component 3-86 by a distance. In this way, the shielding portion 3-143 on the housing 3-10 can shield and ensure that the sensing component 3-82 and the electronic component 3-86 are not hit by foreign objects, thereby improving the safety of the sensing component 3-82 and the electronic component 3-86 in use.
[0356] Next, please refer to Figures 42-43 , Figure 42 A perspective view showing a driving mechanism 3-1 according to another embodiment of the present disclosure is shown. Figure 43 It means along Figure 42 The cross-sectional view of the midline segment (3-Y5)-(3-Y5). Figures 42-43 As shown, the driving mechanism 3-1 of this embodiment mainly includes an optical component 3-L (for example, a prism or a reflector), a carrier 3-50, at least one coil 3-C, at least one magnetic component 3-M, a circuit board 3-70 and a shell 3-90, wherein the aforementioned optical component 3-L can reflect the incident light traveling along the -Z axis direction into the outgoing light traveling along the -X axis direction (as shown in FIG. Figure 43 (in the direction of the arrow).
[0357] It should be understood that the aforementioned carrier 3-50 carries the optical component 3-L and can constitute a movable module of the drive mechanism 3-1. The aforementioned circuit board 3-70 is fixed to the housing 3-90 and can together constitute a fixed module of the drive mechanism 3-1. The aforementioned movable module and fixed module can be interconnected through at least one elastic component (not shown) so that the movable module can be suspended within the fixed module. In addition, the aforementioned magnetic component 3-M and coil 3-C are respectively placed on the carrier 3-50 and the circuit board 3-70 and can together constitute a drive component to drive the aforementioned movable module to move or rotate relative to the fixed module.
[0358] When an electric current is transmitted to the coil 3-C via the circuit board 3-70, an electromagnetic driving force is generated between the magnetic component 3-M and the coil 3-C to drive the carrier 3-50 to move relative to the circuit board 3-70 and the housing 3-90. The sensing component 3-82 disposed on the circuit board 3-70 can sense changes in the magnetic field of the magnetic component 3-M or the coil 3-C to determine the relative movement between the movable module and the fixed module, thereby enabling rapid and effective motion control of the optical component 3-L through the drive mechanism 3-1. The sensing component 3-82 can form a position sensing component with the magnetic component 3-M or the coil 3-C.
[0359] In the present embodiment, the aforementioned sensing component 3-82 and the shell 3-90 are both disposed on the outer surface 3-74 of the circuit board 3-70, wherein the shell 3-90 has a through-hole 3-92, the sensing component 3-82 is disposed in the through-hole 3-92, and its outer wall surface 3-821 is closer to the circuit board 3-70 than an outer side surface 3-93 of the shell 3-90, so that the sensing component 3-82 does not protrude from the circuit board 3-70, thereby preventing the sensing component 3-82 from being damaged by collision with external objects.
[0360] Next, please refer to Figure 44 , Figure 44 express Figure 42 The schematic diagram of the through hole 3-92 after being filled with adhesive 3-G. Figure 44 As shown, during assembly, adhesive 3-G can be applied in the aforementioned through-hole 3-92, wherein the adhesive 3-G will cover the sensing component 3-82 to increase the bonding strength between the circuit board 3-70, the sensing component 3-82 and the housing 3-90, and the adhesive 3-G can be used to protect the sensing component 3-82 to prevent the sensing component 3-82 from being damaged by collision with external objects, thereby improving safety in use.
[0361] See also Figure 45 , Figure 45 A cross-sectional view showing a driving mechanism according to another embodiment of the present disclosure, wherein Figure 45 Examples and Figures 42-44The main difference between the embodiment of the present invention and the embodiment of the present invention lies in that a stop wall 3-94 is further formed on the housing 3-90. The stop wall 3-94 seals the aforementioned through-hole 3-92 and covers the sensing element 3-82. A distance is provided between the outer wall surface 3-821 of the sensing element 3-82 and the stop wall 3-94. In this way, the stop wall 3-94 protects the sensing element 3-82 from being damaged by external objects, thereby ensuring the normal operation of the sensing element 3-82.
[0362] In summary, the driving mechanism disclosed herein mainly arranges the sensing components and / or electronic components on the outer surface of the circuit board to prevent the sensing components and / or electronic components from being damaged by collisions with the carrier or other internal components during use, thereby improving the reliability and stability of the driving mechanism.
[0363] Furthermore, since the sensing component is not positioned protruding from the outer surface of the housing, and the sensing component and / or the electronic component can be covered by an adhesive or a shielding portion / stop wall on the housing, the sensing component and / or the electronic component will not be damaged by impact from external objects, thereby ensuring the normal operation of the sensing component and / or the electronic component.
