Description

Technical Field

[0001] This disclosure relates to an optical element driving mechanism. Background Technology

[0002] With the development of technology, many electronic devices today (such as smartphones or digital cameras) have the function of taking pictures or recording videos. The use of these electronic devices is becoming more and more common, and they are developing towards convenient and thinner designs to provide users with more choices.

[0003] The aforementioned electronic devices with photographic or video recording functions typically include an optical element driving mechanism to drive optical elements (such as a lens) to move along the optical axis, thereby achieving autofocus (AF) or optical image stabilization (OIS). Light can pass through the aforementioned optical elements and form an image on the photosensitive element. However, the current trend in mobile devices is to achieve smaller size and higher durability; therefore, effectively reducing the size of the optical element driving mechanism and improving its durability has become an important issue.

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 background or context of this disclosure, and should not be interpreted in an idealized or overly formal manner, unless specifically defined herein.

[0107] Furthermore, the use of ordinal numbers such as "first" and "second" in the specification and claims to modify elements of the claims does not imply or represent any prior ordinal number for the claimed element, nor does it represent the order of one claimed element with another, or the order of manufacturing methods.

[0109] First, please refer to Figures 1A to 1F ,in Figure 1A This is a schematic diagram of an optical element driving mechanism 1000 according to some embodiments of this disclosure. Figure 1B This is an exploded view of the optical element drive mechanism 1000. Figure 1C This is a top view of the optical element drive mechanism 1000. Figure 1D It is along Figure 1C The cross-sectional view shown by line segment AA, Figure 1E yes Figure 1D Enlarged image, Figure 1F It is along Figure 1C The cross-sectional view is shown by line segment BB. Figure 2A , Figure 2B This is a perspective view of some components of the optical element drive mechanism 1000.

[0110] like Figures 1A to 2B As shown, the optical element driving mechanism 1000 mainly includes a fixing part 100 (including a housing 110 and a base 120) arranged along the main axis 900, a first support 200, a second support 300, a base 400, a guide assembly 500 (including a first guide element 510 and a second guide element 520), a first drive assembly 600, a second drive assembly 700 (including a conductive element 710, a driving force source 720, and a counterweight element 730), and a second sensing assembly 800. The optical element driving mechanism 1000 can be used to drive an optical element (not shown) to move in order to achieve the effects of autofocus (AF) or optical image stabilization (OIS).

[0111] In some embodiments, the aforementioned optical elements may include, for example, lenses, mirrors, prisms, beam splitters, apertures, liquid lenses, image sensors, camera modules, and ranging modules. It should be noted that the definition of optical elements here is not limited to elements related to visible light; elements related to invisible light (e.g., infrared light, ultraviolet light) may also be included in this work.

[0112] The aforementioned housing 110 and base 120 can be combined to form the housing of the optical element driving mechanism 1000. For example, the base 120 can be fixedly connected to the housing 110. It should be understood that the housing 110 and the base 120 are respectively formed with an outer frame opening and a base opening, wherein the center of the outer frame opening corresponds to the main axis 900 of the optical element, and the base opening corresponds to the image sensing element (not shown) disposed outside the optical element driving mechanism 1000; thereby, the optical element disposed in the optical element driving mechanism 1000 can focus with the image sensing element in the direction extending from the main axis 900.

[0113] The first support 200 and the second support 300 can be used to connect optical elements. Specifically, the first support 200 is movable relative to the fixed part 100, and the base 400 can be fixed to the first support 200. The second support 300 is movably connected to the base 400, that is, the second support 300 is movable relative to the fixed part 100 and the base 400. The optical element can be fixed in the through hole 320 of the second support 300 so as to move together with the second support 300. The first drive assembly 600 can be used to drive the first support 200 to move relative to the fixed part 100, and the second drive assembly 700 can be used to drive the second support 300 to move relative to the fixed part 100 and the base 400. Figure 1E As shown, the first support 200 may be located between the base 120 and the base 400. In some embodiments, the first support 200 may be made of metal, while the second support 300 may be made of non-metallic material.

[0114] The housing 110 may include a top wall 111 and a plurality of side walls extending from the top wall 111, such as a first side wall 112. The top wall 111 has a plate-like structure and is perpendicular to the main axis 900. The first side wall 112 has a plate-like structure and is not parallel to the top wall 111. The base 120 may be arranged with the top wall 111 along the main axis 900. The top wall 111, the first side wall 112, and the base 120 surround a receiving space 130, which may be used to receive various components of the optical element driving mechanism 1000, such as a first support 200, a second support 300, etc. In some embodiments, a first driving assembly 600 may be at least partially fixedly disposed on the first support 300, for example, by connecting the base 120 and the first support 300.

[0115] An axis passing through the center of the base 400 and perpendicular to the main axis 900 can be defined as the first axis 910, for example, an axis extending along the X direction. When viewed along the first axis 910, as... Figure 1D As shown, the base 400 is at least partially located between the first support 200 and the second support 300, and the second drive assembly 700 is at least partially located between the base 400 and the first support 200, with the second drive assembly 700 at least partially exposed on the base 400. When viewed along the first axis 910, the first guide element 510 and the second drive assembly 700 (e.g., the conduction element 710) at least partially overlap.

[0116] The conductive element 710 of the second drive assembly 700 can be used to transmit the driving force generated by the drive force source 720, and the counterweight element 730 can be disposed on the drive force source 720, which can be located between the conductive element 710 and the counterweight element 730. The conductive element 710 may have an elongated structure and extend along the second axis 920. The material of the conductive element 710 may include a non-metallic material, such as carbon (e.g., graphite). Thus, the conductive element 710 can be disposed on the second support 300 through frictional contact. When the force between the second support 300 and the conductive element 710 is less than the maximum static friction, the second support 300 can move together with the conductive element 710. When the force between the second support 300 and the conductive element 710 is greater than the maximum static friction, the second support 300 can move relative to the conductive element 710.

[0117] The second shaft 920 may be parallel to the main shaft 900, but is not limited thereto. The material of the driving force source 720 may include a piezoelectric material. That is, when an electric field (voltage) is applied to the surface of the driving force source 720, the electric dipole moment of the driving force source 720 is lengthened, and the driving force source 720 elongates along the direction of the electric field to resist the change. Therefore, electrical energy can be converted into mechanical energy. In some embodiments, an electric field may be applied to the driving force source 720 to change the length of the driving force source 720 on the second shaft 920 (e.g., elongation or shortening). The material of the counterweight element 730 may include a metal, such as a high-density metal like tungsten steel or iron, to maintain the overall stability of the second drive assembly 700.

[0118] In some embodiments, the guide assembly 500 can be used to guide the movement of the second support 200 relative to the base 400. The first guide element 510 and the second guide element 520 can pass through the second support 300 and the base 400, and can extend along the second axis 920. For example, the first guide element 510 and the second guide element 520 can be fixed to the base 400 and movably connected to the second support 300 to guide the direction of movement of the second support 300 relative to the base 400. When viewed along the second axis 920, the base 400 has a polygonal structure, the first guide element 510 and the second drive assembly 700 are located at a first corner 141 of the optical element drive mechanism 1000, the second guide element 520 is located at a second corner 142 of the optical element drive mechanism 1000, and the center line 530 connecting the first guide element 510 and the second guide element 520 passes through the through hole 320 of the second support 300.

[0119] Figure 3This is a top view of the base 120, the first support 200, and the first drive assembly 600. The optical element drive mechanism 1000 may have a polygonal shape and may include a first corner 141, a second corner 142, a third corner 143, and a fourth corner 144. The first corner 141 may be opposite to the second corner 142, and the third corner 143 may be opposite to the fourth corner 144. In some embodiments, the first circuit assembly 153 may be disposed on the first support 200, for example, disposed on the surface of the first support 200, or embedded in the first support 200.

[0120] The first circuit assembly 153 is electrically connected to the first drive assembly 600, the second drive assembly 700, and the second sensing assembly 800. The first drive assembly 600 may include a plurality of first drive elements 160, each of which may have an elongated shape. The first connecting portion 171 may be located at the first corner 141 and the second corner 142, while the second connecting portion 172 may be located at the third corner 143 and the fourth corner 144. The first connecting portion 171 may be connected to the first carrier 200, while the second connecting portion 172 may be connected to the base 120. One end of the first drive element 160 may be disposed in the first connecting portion 171, and the other end may be disposed in the second connecting portion 172. In other words, the first carrier 200 can be connected to the base 120 through the first drive assembly 600.

[0121] In some embodiments, the material of the first driving element 160 may include a shape memory alloy and have an elongated shape. A shape memory alloy is an alloy material that, when heated, can completely eliminate the deformation that occurred at a lower temperature and restore its original shape before deformation. For example, when a shape memory alloy is subjected to a limited degree of plastic deformation below the phase transformation temperature, it can be restored to its original shape before deformation by heating.

[0122] In some embodiments, when a signal (e.g., voltage or current) is applied to the first driving element 160, the temperature can be increased due to the thermal effect of the current, thereby reducing the length of the first driving element 160. Conversely, if a weaker signal is applied, the temperature can be reduced because the heating rate is lower than the heat dissipation rate of the environment, thereby increasing the length of the first driving element 160. Thus, the first driving assembly 600 can drive the first support 200 to move relative to the fixed portion 100. For example, the first driving assembly 600 can drive the first support 200 to move (e.g., translate or rotate) in a plane perpendicular to the main shaft 900 to achieve optical image stabilization.

[0123] In some embodiments, each of the first drive elements 160 may be located on the same virtual plane (not shown), such as a plane with a normal vector in the Z direction, so as to control the direction of the force applied by the first drive assembly 600 to the first support 200 in the XY plane.

[0124] In some embodiments, additional circuitry may be provided on the base 120, for example, embedded in the base 120 or exposed on the surface of the base 120, and connected to the aforementioned circuitry via the first electrical contact 151 and the second electrical contact 152. In some embodiments, the circuitry connected to the first electrical contact 151 and the second electrical contact 152 may be electrically insulated from each other, but this is not a limitation.

[0125] In some embodiments, the base 400 may also have a first stop assembly 444 (e.g., including a first stop element 441 and a second stop element 442), which can limit the range of movement of the first support 200 and the second support 300 relative to the base 400 or relative to the fixing part 100 by contact. A first recess 443 may also be provided between each of the first stop elements 441, and the first stop elements 441 and the first recess 443 may be located on the same side of the base 400 to avoid a single first stop element 441 with an excessively large area from adhering to the housing 110.

[0126] In some embodiments, the first recess 443 may correspond to the first sidewall 112, i.e., face the first sidewall 112. The second stop element 442 may be located at the second corner 142, and the second stop element 442 may be located at different corners of the optical element driving mechanism 1000 from the first guide element 510, the second guide element 520, and the second drive assembly 700. By designing the second stop element 442 to be offset from the first guide element 510, the second guide element 520, and the second drive assembly 700, the space at the corners of the optical element driving mechanism 1000 can be further utilized to achieve miniaturization and ensure smooth movement of each element.

[0127] Figure 4A This is a top view of some components of the optical element drive mechanism 1000. Figure 4B This is a side view of some components of the optical element drive mechanism 1000. Figure 4C Enlarged side view of some components of the optical element drive mechanism 1000. Figure 4D It is along Figure 1C The cross-sectional view shown by line segment CC.

[0128] In some embodiments, the base 400 may have a first recessed structure 430 for accommodating a portion of the second drive assembly 700. For example, a first sidewall 112 and a base 120 are located around the first recessed structure 430, while a drive force source 720 and a counterweight element 730 may be located in the first recessed structure 430.

[0129] Figure 5A , Figure 5B This is a schematic diagram of some components of the optical element drive mechanism 1000, and... Figure 6A , Figure 6B This is a schematic diagram of the base 400 viewed from different directions. The base 400 may include a first base surface 401, a second base surface 402, a third base surface 403, a fourth base surface 404, a first opening 421, and a second opening 422. The first base surface 401, the second base surface 402, the third base surface 403, and the fourth base surface 404 may be parallel to each other and perpendicular to the second axis 920, and the first opening 421 may be located on the first base surface 401 and the third base surface 403, and the second opening 422 may be located on the second base surface 402 and the fourth base surface 404. The first base surface 401 and the second base surface 402 may face away from the first support 200, while the third base surface 403 and the fourth base surface 404 may face the first support 200.

[0130] The first opening 421 can be used to accommodate the conductive element 710, and the second opening 422 can be used to accommodate the first guiding element 510. For example... Figure 5A As shown, when viewed along the second axis 920, the maximum size D1 of the first opening 421 is different from the maximum size D2 of the second opening 422. For example, the maximum size D1 of the first opening 421 may be smaller than the maximum size D2 of the second opening 422. Furthermore, the maximum size D1 of the first opening 421 may be smaller than the maximum size W1 of the first guide element 710, so as to allow the first guide element 710 to be disposed in the first opening 421 in a close-fitting manner.

[0131] For example, a first end 711 of the first guiding element 710 may be disposed in the first opening 421, while a second end 712 of the first guiding element 710 may protrude from the first opening 421 and not contact any other element, i.e., the second end 712 does not require additional fixing. In some embodiments, the maximum size D1 of the first opening 421 may be at least one-third larger than the maximum size W1 of the first guiding element 710 to allow the first guiding element 710 to be disposed in the first opening 421.

[0132] In some embodiments, the base 400 further includes a second recessed structure 423 and a third recessed structure 424. The second recessed structure 423 is formed on the second base surface 402, while the third recessed structure 424 is formed on the fourth base surface 404. The second recessed structure 423 and the third recessed structure 424 may be adjacent to the second opening 422. Viewed along the main axis 900, the second recessed structure 423 has an arcuate surface (e.g., a radius R), and the maximum dimension D3 of the second recessed structure 423 may be greater than the maximum dimension D2 of the second opening 422. Furthermore, the third recessed structure 424 has a planar surface (e.g., a radius C), and the maximum dimension D4 of the third recessed structure 424 may be greater than the maximum dimension D2 of the second opening 422. Thus, the first guide element 510 can be more easily inserted into the second opening 422. It should be noted that the second recessed structure 423 and the third recessed structure 424 may have different structures (e.g., a radius R and a radius C). In some embodiments, when viewed along the main axis 900, the maximum size D4 of the third recessed structure 423 is different from the maximum size D3 of the second recessed structure 422, for example, the maximum size D4 of the third recessed structure 423 is greater than the maximum size D3 of the second recessed structure 422.

[0133] Furthermore, the optical element driving mechanism 1000 may also include a first connecting element 461, a second connecting element 462, a third connecting element 463, a fourth connecting element 464, and a fifth connecting element 465. The first connecting element 461 and the second connecting element 462 may be at least partially disposed in the first recessed structure 430. The third connecting element 463 may be disposed between the base 400 and the first support 200. The fourth connecting element 464 can be used to connect the conductive element 710 and the base 400. The counterweight element 730 may be fixedly disposed on the first recessed surface 431 of the first recessed structure 430 via the first connecting element 461. For example, the first recessed surface 431 may be a surface of the first recessed structure 430 parallel to the second axis 920. In other words, the first connecting element 461 may directly contact the counterweight element 730 and the first recessed surface 431, and in a direction perpendicular to the second axis 920 (e.g., the X or Y direction), the first connecting element 431 and the counterweight element 730 at least partially overlap.

[0134] In some embodiments, the counterweight element 730 may be fixedly disposed on the second recessed surface 432 of the first recessed structure 430 via the second connecting element 462, the second recessed surface 432 being, for example, the surface of the first support 200. In other words, the second connecting element 462 may directly contact the counterweight element 730 and the second recessed surface 432, and the second recessed surface 432 is not parallel to the second axis 920 (e.g., it may be perpendicular to each other). In some embodiments, when viewed along the second axis 920, the second connecting element 462 may at least partially overlap with the counterweight element 730. In some embodiments, the first connecting element 461 may directly contact the second connecting element 462 and has an integrated structure.

[0135] In some embodiments, the base 400 may be fixedly connected to the first support 200 via a third connecting element 463, meaning the third connecting element 463 may directly contact the first support 200 and the base 400. In the direction extending along the second axis 920 (Z direction), the first guide element 510 and the second guide element 520 may at least partially overlap with the third connecting element 463. For example, the third connecting element 463 may directly contact the first guide element 510 and the second guide element 520 to fix the relative positions of the first guide element 510, the second guide element 520, and the base 400. In some embodiments, the third connecting element 463 may directly contact the second connecting element 462 and have an integrated structure. In some embodiments, the first connecting element 461, the second connecting element 462, and the third connecting element 463 may be made of a non-metallic material to avoid short circuits.

[0136] In some embodiments, the fourth connecting element 464 may directly contact the conductive element 710 and the first opening 421 of the base 400, and the Young's modulus of the fourth connecting element 464 is different from that of the second connecting element 462 and the third connecting element 463. For example, the Young's modulus of the fourth connecting element 464 may be smaller than that of the second connecting element 462 and the third connecting element 463. That is, the fourth connecting element 464 may be softer than the second connecting element 462 and the third connecting element 463 to allow the conductive element 710 to be movably connected to the base 400.

[0137] In some embodiments, such as Figure 1F , Figure 2A , Figure 2BAs shown, the second sensing component 800 may include a second reference object 820 and a second sensing element 830 for sensing the movement of the second support 300 relative to the base 400. In some embodiments, a first sensing element 810 may be disposed on the first support 200. The first sensing element 810 may also be used to sense changes in the magnetic field of the second reference object 820, and the first sensing element 810 and the second sensing element 830 may be disposed on different sides of the second reference object 820 to sense the movement of the second support 300 relative to the base 400 in different directions. For example, the first sensing element 810 and the second sensing element 830 may include sensing elements such as a Hall effect sensor, a magnetoresistive effect sensor (MR sensor), a giant magnetoresistive effect sensor (GMR sensor), a tunneling magnetoresistive effect sensor (TMR sensor), or a fluxgate sensor. The second reference object 820 may include a magnet.

[0138] The second sensing element 830 and the second reference object 820 may be respectively disposed on the second support 300 and the base 400 (or their positions may be interchanged). For example, the second sensing element 830 may be disposed on the second stop element 442. When the second support 300 moves relative to the base 400, the second sensing element 830 can be used to sense the change in the magnetic field generated by the second reference object 820, thereby obtaining the position of the second support 300 relative to the base 400.

[0139] In some embodiments, the second sensing component 800, the second driving component 700, the first guiding element 510, and the second guiding element 520 may be located at different corners of the optical element driving mechanism 1000. For example, the second sensing component 800 may be located at the third corner 143, the second driving component 700 and the first guiding element 510 may be located at the first corner 141, and the second guiding element 520 may be located at the second corner 142, so as to further utilize the space at each corner of the optical element driving mechanism 1000 and achieve miniaturization.

[0140] In some embodiments, the optical element driving mechanism 1000 may further include a second control component 831, which may be packaged together with the second sensing element 830 of the second sensing component 800. In other words, the second control component 831 may be located at the third corner 143 and fixedly disposed on the first support 300. The second control component 831 may be electrically connected to the first circuit component 153. The second sensing component 800 may output a second sensing signal to the second control component 831, and the second control component 831 may output a second driving signal to the second driving component 700 based on the second sensing signal to control the movement of the second driving component 700. The second sensing signal may include the position of the second support 300 relative to the base 400.

[0141] In some embodiments, the base 400 may further include a second circuit assembly 450, which is fixedly disposed within the base 400. The second circuit assembly 450 may be electrically connected to the second drive assembly 700 and the second sensing assembly 800. For example, the second drive assembly 700 and the second sensing assembly 800 may be electrically connected to the first circuit assembly 153 and the second control assembly 831 via the second circuit assembly 450. The first circuit assembly 153 and the second circuit assembly 450 may have a first electrical contact 151 and a second electrical contact 152 for connecting the first circuit assembly 153 and the second circuit assembly 450. The second circuit assembly 450 may be partially exposed outside the base 400.

[0142] For example, the first electrical contact 151 and the second electrical contact 152 can transmit the aforementioned second driving signal and second sensing signal. Furthermore, the first electrical contact 151 and the second electrical contact 152 can be located at different corners of the optical element driving mechanism 1000. For instance, when viewed along the main axis 900, the first electrical contact 151 is located at the first corner 141, and the second electrical contact 152 is located at the second corner 142, to avoid signal interference.

[0143] In some embodiments, the fifth connecting element 465 may be disposed on the first electrical contact 151, for example, it may cover the first electrical contact 151 to protect the first electrical contact 151. In some embodiments, the fifth connecting element 465 may directly contact the second connecting element 462 and the third connecting element 463, for example, the fifth connecting element 465 may have an integrated structure with the second connecting element 462 and the third connecting element 463. This allows the second connecting element 462 and the third connecting element 463, such as the fifth connecting element 465, to be provided directly in a single process, thereby reducing the number of steps required in the process.

[0144] In some embodiments, the optical element driving mechanism 1000 may further include a foreign object restraint structure 470 for restricting the movement of foreign objects within the receiving space 130. The foreign object restraint structure 470 may include, for example, a first foreign object capturing element 471, a second foreign object capturing element 472, a third foreign object capturing element 473, and a fourth foreign object capturing element 474 for capturing foreign objects. The surfaces of the first foreign object capturing element 471, the second foreign object capturing element 472, the third foreign object capturing element 473, and the fourth foreign object capturing element 474 may be adhesive, for example, they may include a resin material, to capture foreign objects.

[0145] It should be noted that the first groove structure 411 may be formed on the surface 401 of the first base, while the second groove structure 310 may be formed on the surface of the second support 300 facing the base 400. The first foreign object capturing element 471 may be disposed in the first groove structure 411, the second foreign object capturing element 472 may be disposed in the second groove structure 310, the third foreign object capturing element 473 may be disposed on the surface 402 of the second base, and the fourth foreign object capturing element 474 may be disposed on the surface 403 of the third base. Figure 5A As shown, when viewed along the second axis 920, the first foreign object capturing element 471 and the fourth foreign object capturing element 474 can surround the first opening 421 and the conductive element 710 disposed in the first opening 421. In other words, the first groove structure 411 can be adjacent to the conductive element 710.

[0146] In some embodiments, such as Figure 4D As shown, in the direction extending along the second axis 920, the first groove structure 411 may at least partially overlap with the second groove structure 412, that is, the second foreign object capturing element 472 and the first foreign object capturing element 471 may at least partially overlap. Furthermore, in the direction extending along the first axis 910, the maximum dimension L1 of the first groove structure 411 may differ from the maximum dimension L2 of the second groove structure 310; for example, the maximum dimension L1 of the first groove structure 411 may be smaller than the maximum dimension L2 of the second groove structure 310, to ensure that the first foreign object capturing element 471 and the second foreign object capturing element 472 do not completely overlap in the Z direction, thereby preventing adhesion. Since the second foreign object capturing element 472 is disposed on the second support 300, and the first foreign object capturing element 471 is disposed on the base 400, the second foreign object capturing element 472 can move relative to the first foreign object capturing element 471. In some embodiments, on the second axis 920, the center of the first foreign object capturing element 471 and the center of the third foreign object capturing element 473 have a distance greater than zero. When viewed along the second axis 920, the third foreign object capturing element 473 can be closedly surrounding the through hole 320, that is, closedly surrounding the optical element.

[0147] In summary, the embodiments of this disclosure provide an optical element driving mechanism, including a first carrier, a fixing part, a first driving assembly, and a first stopping assembly. The first carrier is used to connect the optical element. The first carrier is movable relative to the fixing part. The first driving assembly is used to drive the first carrier to move relative to the fixing part. The first stopping assembly is used to limit the range of movement of the first carrier relative to the fixing part. Thus, automatic focusing and optical image stabilization functions can be achieved, and miniaturization can also be realized.

[0148] The specific relative positions and size relationships of the components disclosed in this disclosure not only enable the drive mechanism to achieve thinning in a specific direction and overall miniaturization, but also further improve the optical quality of the system (such as shooting quality or depth sensing accuracy) by matching different optical modules, and further utilize each optical module to achieve a multi-stage anti-shake system to greatly improve the anti-shake effect.
