Description

Technical Field

[0001] This invention relates to an optical component driving mechanism. More specifically, this invention relates to an optical component driving mechanism with an adjustable aperture size. Background Technology

[0002] With the advancement of technology, many electronic devices today (such as cameras or smartphones) have photo or video recording capabilities. However, incorporating lenses with longer focal lengths into these devices increases their thickness, hindering their miniaturization. Furthermore, current miniature camera modules on the market primarily use fixed-aperture designs, resulting in limited adjustability for image sharpness and brightness in small, portable electronic devices. When the sensor can support the image and sufficient light is available, a smaller aperture is needed to achieve better image resolution. However, using a fixed aperture leads to poor image quality in low-light conditions (such as at night). Therefore, a fixed aperture must compromise on photographic capabilities in different environments. Summary of the Invention

[0080] The following describes the optical component driving mechanism of an embodiment of the present invention. However, it will be readily apparent that the embodiments of the present invention provide many suitable inventive concepts and can be implemented in a wide range of specific contexts. The specific embodiments disclosed are merely illustrative of the use of the present invention in a particular manner and are not intended to limit the scope of the present invention.

[0081] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. It is understood that these terms, such as those defined in commonly used dictionaries, shall be interpreted as having a meaning consistent with the relevant art and the background or context of this utility model, and shall not be interpreted in an idealized or overly formal manner, unless specifically defined herein.

[0082] The following disclosure of this specification describes specific examples of the various components and their arrangements in order to simplify the explanation. Of course, these specific examples are not intended to limit the present invention. For example, if the following disclosure of this specification describes a first feature formed on or above a second feature, it means that it includes embodiments where the formed first feature and the second feature are in direct contact, and also includes embodiments where additional features may be formed between the first feature and the second feature, so that the first feature and the second feature may not be in direct contact. Furthermore, to facilitate the description of the relationship between one feature and another in the drawings, spatial terms such as "below," "under," "below," "above," "above," and similar terms may be used. In addition to the orientations shown in the drawings, spatial terms cover different orientations of the device during use or operation. The device may also be positioned otherwise (rotated 90 degrees or in other orientations), and the spatial descriptions used herein may be interpreted accordingly.

[0083] Figure 1 This is a schematic diagram showing an optical component driving mechanism 10 according to an embodiment of the present invention. Figure 2 This is an exploded view of the aforementioned optical component driving mechanism 10, and Figure 3 It means Figure 1 A cross-sectional view along the AA direction. (See example...) Figures 1 to 3 As shown, multiple optical components 20 can be connected to an optical component driving mechanism 10, which can drive the optical components 20 to rotate, thereby controlling the range through which external light can pass. For example, the optical component driving mechanism 10 can be positioned above a lens or a photosensitive element and can be used as an aperture.

[0084] The optical component driving mechanism 10 mainly includes a fixed part 100, a movable part 200, a driving component 300, a pressurizing component 400, and a position sensing component 500. The fixed part 100 includes a cover 110 and a base 120, which can be combined with each other to form a housing. The movable part 200, the driving component 300, and the pressurizing component 400 can be housed in the internal space 101 of the housing to prevent damage caused by impact from external components. The base 120 may include a main body 121 and a side plate 122, which are detachably combined to facilitate the assembly of the movable part 200, the driving component 300, and the pressurizing component 400.

[0085] The movable part 200 includes a rotating component 210 and two positioning balls 220. The rotating component 210 can be connected to the fixed part 100 via the positioning balls 220 and the drive component 300, and can rotate relative to the fixed part 100 about a second axis AX2. The positioning balls 220 can be disposed on the fixed part 100 and can contact the fixed part 100 and the rotating component 210.

[0086] Specifically, the contact points of the two positioning balls 220 and the rotating component 210, as well as the contact points of the driving component 300 and the rotating component 210, can roughly form an equilateral triangle or an isosceles triangle, thereby clamping the rotating component 210 and suspending it in the internal space 101 of the fixing part 100. In this embodiment, the optical component driving mechanism 10 may also include a soft component S, which fills between the inner wall surface of the fixing part 100 and the positioning balls 220 and contacts both, to ensure contact between the positioning balls 220 and the rotating component 210. For example, the soft component S may include a sponge or foam, but is not limited to these.

[0087] like Figure 2 and Figure 4 As shown, the cover 110 may have a plurality of fixed posts 111 extending toward the rotating assembly 210, and the rotating assembly 210 may have a plurality of guide posts 211 extending in opposite directions. Each optical component 20 may have a shaft hole 21 and a guide groove 22, through which the fixed posts 111 pass and the guide posts 211 pass through the guide groove 22. The diameter of the shaft hole 21 is approximately the same as the diameter of the fixed post 111, and the size of the guide groove 22 is larger than the size of the guide post 211. Therefore, when the rotating assembly 210 rotates relative to the fixed part 100, the fixed posts 111 can act as a pivot, and the guide posts 211 can move along the guide groove 22, thereby driving the optical component 20 to rotate around the fixed posts 111.

[0088] Please return Figures 1 to 3The drive assembly 300 includes a counterweight assembly 310, a piezoelectric assembly 320, and a transmission assembly 330, wherein the piezoelectric assembly 320 is disposed between the counterweight assembly 310 and the transmission assembly 330, and the counterweight assembly 310, the piezoelectric assembly 320, and the transmission assembly 330 are sequentially arranged along a first axis AX1. The first axis AX1 is substantially perpendicular to a second axis AX2.

[0089] A counterweight assembly 310 is mounted on the fixed portion 100. A piezoelectric assembly 320 is connected to the counterweight assembly 310. A transmission assembly 330 is connected to the piezoelectric assembly 320 and contacts the rotating assembly 210 of the movable portion 200. The piezoelectric assembly 320 is deformable along a first axis AX1, and the mass of the counterweight assembly 310 is greater than the masses of the piezoelectric assembly 320 and the transmission assembly 330. Therefore, when the drive assembly 300 operates, the piezoelectric assembly 320 will deform primarily along the first axis AX1 toward the transmission assembly 330, thereby displacing the transmission assembly 330 and providing a driving force to the rotating assembly 210, causing the rotating assembly 210 to rotate about a second axis AX2.

[0090] For example, the counterweight component 310 may include tungsten or other suitable metals, the piezoelectric component 320 may include ceramic, quartz, or other suitable materials, and the transmission component 330 may include carbon fiber or other suitable materials.

[0091] Additionally, it should be noted that the counterweight component 310 is not rigidly fixed to the fixing part 100 by components such as screws, rivets, or hard glue, but is attached to the fixing part 100 by, for example, soft glue K. This improves the driving effect of the drive component 300.

[0092] Please see Figures 3 to 5 The transmission component 330 has a first end 331 and a second end 332. The first end 331 is connected to the piezoelectric component 320, and the second end 332 is opposite to the first end 331. A gap G is provided between the second end 332 and the wall surface of the fixing part 100 to prevent the transmission component 330 from impacting the fixing part 100 and causing damage when it moves. The upper and lower parts of the transmission component 330 can be connected to the fixing part 100 via a flexible component 340, thereby preventing the drive component 300 from tilting relative to the first axis AX1 due to the weight or shaking of the component. The flexible component 340 is disposed between the first end 331 and the second end 332 to avoid affecting the driving effect of the drive component 300.

[0093] The flexible component 340 may include, for example, silicone or adhesive, but is not limited thereto.

[0094] Please see Figure 6AIn this embodiment, the transfer component 330 has a circular cross-section, and the rotating component 210 has a concave structure 212, which has an arc-shaped cross-section. The radius of curvature of the arc-shaped cross-section of the concave structure 212 is greater than the radius of curvature of the circular cross-section of the transfer component 330. Therefore, when the optical component driving mechanism 10 is assembled, a portion of the transfer component 330 can be accommodated in the concave structure 212, and the transfer component 330 and the rotating component 210 can contact each other at a single contact point.

[0095] Please see Figure 6B In some embodiments, the concave structure 212 of the rotating component 210 has a first inclined surface C1 and a second inclined surface C2, and an included angle θ of less than 180 degrees can be formed between the first inclined surface C1 and the second inclined surface C2. When the optical component driving mechanism 10 is assembled, the transmission component 330 can contact the first inclined surface C1 at one contact point and the second inclined surface C2 at another contact point. By increasing the number of contact points, the stability and efficiency of the transmission component 330 in driving the rotating component 210 to rotate can be improved.

[0096] Please see Figure 6C In some embodiments, the concave structure 212 of the rotating component 210 has a contact surface C3, which is a plane parallel to the second axial direction AX2. When the optical component drive mechanism 10 is assembled, the transmission component 330 and the contact surface C3 will make contact at a single contact point.

[0097] like Figures 1 to 3 As shown, the pressurizing assembly 400 includes a pressurizing component 410, which may be a metal spring. The pressurizing component 410 includes a first fixed end 411, a second fixed end 412, and a contact section 413. The first fixed end 411 and the second fixed end 412 are fixed to the side plate 122 of the base 120 of the fixing part 100, and the contact section 413 can contact the transmission component 330 of the driving assembly 300.

[0098] When installing the optical component drive mechanism 10, the movable part 200 and the drive component 300 can first be positioned on the base 120 above the main body 121. Next, the side plate 122, which has a pressure component 410, can be laterally engaged with the main body 121. When the side plate 122 is engaged with the main body 121, the pressure component 410 can contact the transmission component 330 and provide a thrust to the transmission component 330 through its elastic force, keeping the transmission component 330 and the rotating component 210 in contact. The direction of the aforementioned thrust is approximately perpendicular to the first axis AX1 and the second axis AX2.

[0099] In this embodiment, on the first axial direction AX1, the contact segment 413 is located between the first fixed end 411 and the second fixed end 412, and the contact segment 413 has a plane. Therefore, the contact segment 413 and the transmission component 330 can contact on a line segment.

[0100] like Figure 2 and Figure 7 As shown, the position sensing component 500 includes an annular magnetic component 510, a circuit board 520, and a sensor 530. The annular magnetic component 510 is connected to the lower part of the rotating component 210 of the movable part 200, the circuit board 520 is disposed on the base 120 of the fixed part 100, and the sensor 530 is disposed on the circuit board 520 and located on one side of the annular magnetic component 510.

[0101] The sensor 530 can obtain the orientation of the rotating component 210 relative to the fixed part 100 by detecting changes in the magnetic field of the annular magnetic component 510. For example, the sensor 530 may include a Hall 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, but is not limited to these.

[0102] In this embodiment, the base 120 of the fixing part 100 may have an opening 123, and the annular magnetic component 510 and the sensor 530 may be exposed through the aforementioned opening 123, so as to miniaturize the optical component driving mechanism 10.

[0103] Please see Figure 8 In some embodiments of this utility model, the positioning ball of the movable part 200 may be omitted, and the movable part 200 may also include a bearing 230. The bearing 230 may connect the rotating component 210 and the fixed part 100, so that the rotating component 210 can rotate relative to the fixed part 100, and the rotating component 210 can be prevented from moving relative to the fixed part 100 when the optical component drive mechanism 10 shakes.

[0104] Please see Figure 9In another embodiment of this utility model, the first fixed end 411, the contact segment 413, and the second fixed end 412 of the pressurizing component 410 can be arranged sequentially along the second axial direction AX2. Therefore, on the second axial direction AX2, the contact segment 413 will be located between the first fixed end 411 and the second fixed end 412. The contact segment 413 may have a V-shaped structure, and when the optical component driving mechanism 10 is assembled, the contact segment 413 and the transmission component 330 can contact on two parallel line segments.

[0105] Please see Figure 10 In another embodiment of this utility model, the first fixed end 411 and the second fixed end 412 of the pressurizing component 410 are movably connected to the fixing part 100, and the pressurizing component 400 may also include a ball assembly 420, a contact section 413 that contacts the pressurizing component 410, and a side plate 122 of the base 120. Specifically, the side plate 122 may have two guide grooves 122A along the first axial direction AX1, and the first fixed end 411 and the second fixed end 412 may be slidably disposed in the two guide grooves 122A. Therefore, when the driving component 300 starts driving, the pressurizing component 410 will move along with the movement of the transmission component 330.

[0106] The features of the aforementioned embodiments can be freely mixed and matched as long as they do not violate the creative spirit or conflict with each other.

[0107] In summary, this utility model provides an optical component driving mechanism, including a movable part, a fixed part, and a driving component. The movable part is used to connect an optical component and is movable relative to the fixed part. The driving component is used to drive the movable part to move.
