[0081] 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.

[0082] 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.

[0083] 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, spatially related terms such as "below," "below," "under," "above," "above," and similar terms may be used. In addition to the orientations shown in the drawings, spatially related 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 spatially related descriptions used herein can be interpreted accordingly.

[0084] Please refer to the following first. Figure 1In one embodiment of this utility model, the optical component driving mechanism 10 can be installed within an electronic device 20 to carry and drive an optical component 30. This allows the optical component 30 to move relative to a photosensitive component (not shown) in the electronic device 20 along an optical axis AX of the optical component driving mechanism 10, thereby achieving focusing, zooming, and / or optical image stabilization (OIS). For example, the aforementioned electronic device 20 can be a smartphone, tablet computer, or digital camera, and the aforementioned optical component 30 can be a lens with multiple lenses, but is not limited thereto.

[0085] Figure 2 and Figure 3 These are schematic diagrams and exploded views of the aforementioned optical component driving mechanism 10, respectively. Figure 4 It means Figure 2 A cross-sectional view along the AA direction. (See example...) Figures 2 to 4 As shown, the optical component driving mechanism 10 mainly includes a fixed part 100, a movable part 200, a driving component 300, a guiding component 400, and a clamping component 500.

[0086] The fixing part 100 includes a frame 110 and a base 120, and the frame 110 and the base 120 can be joined together to form an accommodating space 101 between them. The movable part 200, the drive assembly 300, and the guide assembly 400 can be accommodated in this accommodating space 101 and are therefore protected by the fixing part 100. The drive assembly 300 can be fixed to the frame 110, and the movable part 200 can be movably connected to the drive assembly 300. Therefore, the drive assembly 300 can provide a driving force to the movable part 200, causing the movable part 200 to move relative to the fixing part 100.

[0087] In detail, the driving component 300 may include an amplification component 310, a driving source 320, and a transmission component 330. The amplification component 310, the driving source 320, and the transmission component 330 may be arranged along a direction parallel to the optical axis AX. Therefore, the driving component 300 may have a generally elongated structure extending along the direction parallel to the optical axis AX. The frame 110 of the fixing part 100 may have a first surface S1 and a fourth surface S4. The first surface S1 faces the light incident side 11 of the optical component driving mechanism 10, and the fourth surface S4 faces the driving component 300 and is opposite to the first surface S1. The first surface S1 and the fourth surface S4 are generally perpendicular to the extension direction of the driving component 300. The amplification component 310 may be fixed to the fourth surface S4 of the frame 110 by the first connecting component C1. The driving source 320 may be connected to the amplification component 310, and when viewed along the direction perpendicular to the optical axis AX, the amplification component 310 is disposed between the driving source 320 and the first surface S1. The conductive component 330 can be connected to the drive source 320, and when viewed along the direction perpendicular to the optical axis AX, the drive source 320 is located between the conductive component 330 and the first surface S1. The shortest distance between the drive source 320 and the first surface S1 on the frame 110 facing the light incident side 11 can be less than the shortest distance between the drive source 320 and the second surface S2 on the base 120 facing the light emitting side 12.

[0088] The drive source 320 may include a piezoelectric component. When current flows into the drive source 320, the length of the drive source 320 will change in a direction parallel to the optical axis AX, thereby providing a driving force to the conductive component 330 connected to the drive source 320. The conductive component 330 can be movably connected to the movable part 200 via the clamping component 500. Therefore, when the drive source 320 provides a driving force to the conductive component 330, the conductive component 330 can transmit this driving force to the movable part 200 to drive the movable part 200 to move relative to the fixed part 100.

[0089] In this embodiment, the clamping assembly 500 may include a flexible member 510 and one or more metal springs 520. The flexible member 510 may surround the conductive assembly 330, and the flexible member 510 may contact the movable part 200 and the outer surface 521 of the metal spring 520. The metal spring 520 may be disposed between the flexible member 510 and the conductive assembly 330, and the inner surface 522 of the metal spring 520 may contact the conductive assembly 330. In this way, when the driving assembly 300 is not in operation, it can be ensured that the clamping assembly 500 is clamped on the conductive assembly 330, so that the movable part 200 connected to the clamping assembly 500 can be positioned in the desired position. When the driving assembly 300 is in operation, the metal spring 520 can reduce the friction between the metal spring 520 and the conductive assembly 330, and can prevent debris from falling into the receiving space 101 and / or causing the optical component driving mechanism 10 to fail. In this embodiment, the flexible element 510 may include rubber or silicone, but is not limited thereto.

[0090] The amplification component 310 can be used to amplify the driving force provided by the drive source 320. Specifically, the specific gravity of the amplification component 310 can be greater than that of the frame 110 and the base 120, and can also be greater than that of the conduction component 330. For example, the specific gravity of the amplification component 310 can be more than five times that of the frame 110 and the base 120. In this embodiment, the amplification component 310 may include metal, the frame 110 and the base 120 may include resin, and the conduction component 330 may include carbon fiber.

[0091] To ensure sufficient space for deformation of the drive assembly 300, the shortest distance between the drive assembly 300 and the fourth surface S4 of the frame 110 facing the drive assembly 300 can be less than the shortest distance between the drive assembly 300 and the fifth surface S5 of the base 120 facing the drive assembly 300. In this embodiment, the shortest distance between the drive assembly 300 and the fourth surface S4 can be close to zero (i.e., the drive assembly 300 can contact the fourth surface S4), and the shortest distance between the drive assembly 300 and the fifth surface S5 can be greater than 0.15 mm.

[0092] Additionally, a second connecting component C2 may be filled between the drive assembly 300 and the fifth surface S5. The first connecting component C1 and the second connecting component C2 may be, for example, soft rubber. In other words, the fourth surface S4 is provided with a soft material (the first connecting component C1) that contacts one end of the drive assembly 300, and the fifth surface S5 is provided with a soft material (the second connecting component C2) that contacts the other end of the drive assembly 300, thus maintaining the stability of the drive assembly 300 during operation. It should be noted that the Young's modulus of the first connecting component C1 and the second connecting component C2 should be smaller than the Young's modulus of the fixing part 100 and the amplifying component 310 to avoid affecting the driving effect of the drive assembly 300.

[0093] The movable part 200 can be connected to the optical component 30, so that when the driving component 300 drives the movable part 200 to move, the optical component 30 will also move accordingly. The movable part 200 may include a connecting surface 210 facing and connected to the optical component 30.

[0094] The frame 110 of the fixing part 100 may have a first opening 111 formed on a first surface S1 facing the light incident side 11, and the base 120 of the fixing part 100 may have a second opening 121 formed on a second surface S2 facing the light emitting side 12. The positions of the first opening 111 and the second opening 121 may correspond to the mounting position of the optical component 30. Therefore, external light can enter the first opening 111 from the light incident side 11, and after passing through the optical component 30 and the second opening 121 in sequence, it will exit the optical component drive mechanism 10 from the light emitting side 12.

[0095] like Figure 3 and Figure 5 As shown, the movable part 200 can move relative to the fixed part 100 within a range of motion R. When the movable part 200 is located at the center of the range of motion R, it can be defined as being in a default position. At this time, when viewed along the direction perpendicular to the optical axis AX, the shortest distance between the connecting surface 210 and the first surface S1 can be greater than the shortest distance between the connecting surface 210 and the second surface S2.

[0096] With the aforementioned structure of the optical component driving mechanism 10, optical components 30 with any back focal length can be mounted onto the optical component driving mechanism 10. That is, even if the optical component 30 has a large back focal length, it will not be unable to be mounted due to the structural limitations of the optical component driving mechanism 10, nor will it exceed the thickness range of the optical component driving mechanism 10, thus increasing the size of the optical component driving mechanism 10.

[0097] Please refer to the following: Figures 4 to 6 A first recessed structure R1, a second recessed structure R2, at least a first protrusion structure P1, at least a second protrusion structure P2, a third protrusion structure P3, and a fourth protrusion structure P4 may be formed on the second surface S2 of the base 120.

[0098] The first recessed structure R1 is configured to accommodate an optical unit, such as a filter. A first protruding structure P1 protrudes outward from the second surface S2 and is adjacent to the first recessed structure R1. The first protruding structure P1 can be used to position the optical unit. In this embodiment, the second surface S2 has multiple first protruding structures P1 surrounding the first recessed structure R1, and each first protruding structure P1 has an elongated shape.

[0099] The second protrusion P2 protrudes outward from the second surface S2 and is adjacent to the first protrusion P1. The height of the first protrusion P1 protruding from the second surface S2 is greater than the height of the second protrusion P2 protruding from the second surface S2. The position of the second protrusion P2 can correspond to the position of the guide component 400 to increase the structural reliability of the optical component driving mechanism 10.

[0100] The third protruding structure P3 protrudes outward from the second surface S2, located at the edge of the base 120, and surrounding the second opening 121. The second protruding structure P2 is located between the third protruding structure P3 and the first protruding structure P1, and the height of the third protruding structure P3 protruding from the second surface S2 is greater than the height of the first protruding structure P1 protruding from the second surface S2 and the height of the second protruding structure P2 protruding from the second surface S2. The second recessed structure R2 is formed on the second surface S2, located between the second protruding structure P2 and the third protruding structure P3, and is not connected to the first recessed structure R1. The second recessed structure R2 can be used to accommodate an electronic component E1 (e.g., a control IC, sensor, or connection terminal) of the optical component driving mechanism 10.

[0101] The fourth protrusion P4 protrudes outward from the second surface S2, and its position corresponds to the position of the drive component 300. The height of the fourth protrusion P4 protruding from the second surface S2 is greater than the height of the third protrusion P3 protruding from the second surface S2, and the conductive component 330 of the drive component 300 can enter the fourth protrusion P4. Therefore, when viewed along a direction parallel to the second surface S2, the drive component 300 will overlap with the second surface S2, and even more so with the first protrusion P1, the second protrusion P2, and the third protrusion P3, thus achieving miniaturization of the optical component drive mechanism 10.

[0102] Please see Figure 7 In this embodiment, the base 120 may have a third surface S3, with the third surface S3 and the second surface S2 facing opposite directions. A third recessed structure R3 may be formed on the third surface S3, and the position of the third recessed structure R3 corresponds to the position of the movable part 200 or the optical component 30. When viewed along a direction perpendicular to the third surface S3, the third recessed structure R3 overlaps with the first protrusion structure P1 and the second protrusion structure P2.

[0103] Please return Figures 3 to 5 The guide assembly 400 includes a first guide assembly 410 and a second guide assembly 420. The first guide assembly 410 can be fixed to the fixed part 100 and can pass through the movable part 200, so that the movable part 200 is slidably connected to the first guide assembly 410. The first guide assembly 410 and the drive assembly 300 are disposed on the same side of the optical assembly drive mechanism 10, and the first guide assembly 410 is adjacent to the drive assembly 300.

[0104] Similarly, the second guide component 420 can be fixed to the fixed part 100 and can pass through the movable part 200, so that the movable part 200 is slidably connected to the second guide component 420. When viewed from above the optical component drive mechanism 10, the second guide component 420 and the drive component 300 are generally positioned at opposite corners of the optical component drive mechanism 10.

[0105] By using the first guide component 410 and the second guide component 420 of the guide component 400, the situation where the movable part 200 is tilted when the drive component 300 drives the movable part 200 to move can be avoided.

[0106] A third opening 122 and a fourth opening 123, corresponding to the first guide component 410 and the second guide component 420, are formed on the second surface S2 of the base 120 of the fixing part 100. When installing the aforementioned guide component 400, the first guide component 410 and the second guide component 420 can be fixed to the frame 110 of the fixing part 100 first, and after passing through the movable part 200, they can enter the third opening 122 and the fourth opening 123 of the base 120, respectively. Finally, the user can fill the third opening 122 and the fourth opening 123 with adhesive H to fix the first guide component 410 and the second guide component 420.

[0107] like Figure 3 and Figure 5 As shown, in this embodiment, the optical component driving mechanism 10 further includes a magnetic component 800, which is disposed on the movable part 200 and adjacent to the second guide component 420. The first guide component 410 and the second guide component 420 may be made of ferromagnetic material. Therefore, a magnetic attraction will be generated between the second guide component 420 and the magnetic component 800, thereby ensuring that the movable part 200 is attached to the second guide component 420 when it moves.

[0108] Please see Figure 2 and Figure 8 In this embodiment, the optical component driving mechanism 10 further includes a circuit board 600 disposed on the outer surface of the base 120. Multiple electronic components E2 may be disposed on the surface of the circuit board 600 facing the movable part 200. Therefore, a reinforcing plate 610 may be disposed on the surface of the circuit board 600 facing the movable part 200 to prevent the circuit board 600 and / or electronic components E2 from being accidentally damaged during installation.

[0109] Circuit board 600 can be connected to drive source 320 of drive assembly 300 via wire 700. For example... Figure 8 As shown, after the frame 110 and base 120 of the fixing part 100 are combined, a gap G can be formed at the position adjacent to the circuit board 600. The wire 700 can pass through the aforementioned gap G to connect the circuit board 600 and the drive assembly 300.

[0110] 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.
