[0107] 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.

[0108] 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.

[0109] 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.

[0110] Please refer to the following first. Figure 1 In one embodiment of this utility model, the optical component driving mechanism 10 can be installed within an electronic device 20 to support 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 a main 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.

[0111] Figure 2 and Figure 3 These are schematic diagrams and exploded views of the aforementioned optical component driving mechanism 10, respectively. Figure 2 and Figure 3 As shown, the optical component driving mechanism 10 mainly includes a fixed part 100, a movable part 200, a driving component 300, a transmission component 400, a circuit component 500, and a guiding component 600.

[0112] The fixing part 100 includes a lower housing 110 and an upper housing 120, which can be joined together. When viewed from the main axis AX of the optical component drive mechanism 10, the joined fixing part 100 may have a polygonal structure, such as a rectangle, but is not limited thereto. The lower housing 110 may have a bottom wall 111 and a plurality of side walls 112. An optical hole H1 may be formed on the bottom wall 111, and the side walls 112 may be connected to the outer peripheral edge of the bottom wall 111 and extend toward the upper housing 120.

[0113] like Figures 2 to 4 As shown, the upper housing 120 may include a cover 121, a support column 122, and an L-shaped wall 123. An optical hole H2 is formed on the cover 120, its position corresponding to an optical hole H1 on the bottom wall 111. The support column 122 and the L-shaped wall 123 connect to the cover 120 and extend toward the bottom wall 111 of the lower housing 110. The support column 122 and the L-shaped wall 123 are located at opposite corners of the fixing portion 100. When the lower housing 110 and the upper housing 120 are joined, the surfaces of the support column 122 and the L-shaped wall 123 facing the bottom wall 111 can contact the bottom wall 111 and are fixed to the bottom wall 111 by adhesive. In this embodiment, adhesive grooves 122A and 123A can be formed on the surfaces of the support column 122 and the L-shaped wall 123 facing the bottom wall 111, respectively, to facilitate the installation of the fixing part 100 and to prevent excessive adhesive from overflowing.

[0114] The L-shaped wall 123 may have one or more adhesive grooves 123B and one or more recesses 123C formed on its surface facing away from the movable part 200. In this embodiment, some of the recesses 123C can penetrate the L-shaped wall 123, so the movable part 200 can be exposed through these recesses 123C.

[0115] The movable part 200 may have a connection hole 210 for connecting the optical component 30, and the position of the connection hole 210 corresponds to the positions of the optical holes H1 and H2. Therefore, external light can pass through the optical hole H2, the optical component 30 and the optical hole H1 in sequence after entering the optical component drive mechanism 10.

[0116] The drive assembly 300 can be connected to the fixed part 100, and the drive assembly 300 can be connected to the movable part 200 via the transmission assembly 400. In this way, the driving force generated by the drive assembly 300 can be transmitted to the movable part 200 via the transmission assembly 400, so that the movable part 200 moves relative to the fixed part 100.

[0117] Please see Figure 3 and Figure 5 Specifically, the drive assembly 300 may include an amplification assembly 310, a drive source 320, and a transmission assembly 330, and the amplification assembly 310, drive source 320, and transmission assembly 330 may be arranged along a direction parallel to the main shaft AX. The amplification assembly 310 may be fixed to the cover 121 of the upper housing 120 by a soft adhesive G1. The drive source 320 is connected to the amplification assembly 310, and the transmission assembly 330 is connected to the drive source 320, with the drive source 320 disposed between the amplification assembly 310 and the transmission assembly 330.

[0118] The drive source 320 may include a piezoelectric component. When current flows into the drive source 320, its length changes in a direction parallel to the main shaft AX, thereby providing driving force to the conduction component 330. 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 may be greater than that of the fixed portion 100 and also greater than that of the conduction component 330. For example, the specific gravity of the amplification component 310 may be more than five times that of the fixed portion 100. In this embodiment, the amplification component 310 may include metal, and the conduction component 330 may include carbon fiber.

[0119] To ensure sufficient space for deformation of the drive assembly 300, a gap G may be provided between the transmission assembly 330 and the lower housing 110 in a direction parallel to the main shaft AX. This gap G may be, for example, greater than 0.15 mm. In this embodiment, a soft rubber G2 may be filled in the aforementioned gap G to maintain the stability of the drive assembly 300 during operation. Furthermore, a soft rubber G3 may also be provided at the end adjacent to the transmission assembly 330 connected to the drive source 320 to maintain the stability of the drive assembly 300 during operation. It should be noted that the Young's modulus of the soft rubbers G1, G2, and G3 should be smaller than the Young's modulus of the fixing part 100 and the amplifying assembly 310 to avoid affecting the driving effect of the drive assembly 300.

[0120] Please see Figures 3 to 7 The conductive component 400 includes a contact component 410, a contact component 420, and a flexible member 430. The contact component 410 may include a first contact portion 411 and a second contact portion 412 having plate-like structures, with the first contact portion 411 being generally perpendicular to the second contact portion 412. Similarly, the contact component 420 may include a third contact portion 421 and a fourth contact portion 422 having plate-like structures, with the third contact portion 421 being generally perpendicular to the fourth contact portion 422. The flexible member 430 may have a ring-like structure and may include, but is not limited to, rubber or silicone.

[0121] When the drive assembly 300 is connected to the movable part 200 via the conduction assembly 400, the flexible member 430 can surround the contact assembly 410 and the contact assembly 420. The first contact portion 411 and the second contact portion 412 of the contact assembly 410 can contact the inner surface of the flexible member 430 and the conduction assembly 330. The third contact portion 421 and the fourth contact portion 422 of the contact assembly 420 can contact the inner surface of the flexible member 430 and the conduction assembly 330, and the outer surface of the flexible member 430 can contact the movable part 200. In this way, when the drive assembly 300 is not in operation, it can be ensured that the conduction assembly 400 is clamped on the conduction assembly 330, so that the movable part 200 connected to the conduction assembly 400 is positioned in the desired position. The contact assembly 410 and the contact assembly 420 may be metal, so when the drive assembly 300 is in operation, the contact assembly 410 and the contact assembly 420 can reduce the friction between the conduction assembly 400 and the conduction assembly 330.

[0122] Please see Figure 7 and Figure 8 The guide assembly 600 may include a first guide assembly 610 and a second guide assembly 620, both of which have an elongated structure extending along a long axis direction R, which is substantially parallel to the main axis AX of the optical assembly drive mechanism 10. The first guide assembly 610 is fixed to the fixed part 100 and can pass through the hole 220 on the movable part 200, so that when the drive assembly 300 drives the movable part 200 to move relative to the fixed part 100, the movable part 200 can move along the extending direction of the first guide assembly 610.

[0123] The second guide component 620 is fixed to the fixed part 100, adjacent to the drive component 300, and can pass through the hole 230 in the movable part 200. Therefore, when the drive component 300 drives the movable part 200 to move relative to the fixed part 100, the movable part 200 can move along the extending direction of the second guide component 620. It should be noted that the cross-sectional dimension of the hole 220 through which the first guide component 610 passes is slightly larger than the cross-sectional dimension of the first guide component 610, while the cross-sectional dimension of the hole 230 through which the second guide component 620 passes is approximately the same as the cross-sectional dimension of the second guide component 620, which facilitates the assembly of the optical component drive mechanism 10.

[0124] A magnetic component 700 may be provided on the movable part 200, and this magnetic component 700 is adjacent to the first guide component 610. Therefore, the magnetic attraction between the magnetic component 700 and the first guide component 610 can ensure that the movable part 200 is attached to the first guide component 610 when it moves.

[0125] In this embodiment, the angle between the line L connecting the center of the first contact portion 411 of the contact component 410 and the center of the first guide component 610 and the thickness direction of the first contact portion 411 can be less than 10 degrees (for example, it can be 0 degrees, i.e., the first contact portion 411 is perpendicular to the connecting line L), and the magnetic component 700 can be disposed in the extension direction of the aforementioned connecting line L, and the first guide component 610 can be located between the magnetic component 700 and the drive component 300. Therefore, the reliability of the optical component drive mechanism 10 during operation can be further improved.

[0126] Furthermore, when viewed along the main axis AX, the fixing part 100 has a polygonal structure (e.g., a rectangle). Since the first guide assembly 610 and the drive assembly 300 are located at opposite corners of the fixing part 100, the first side 101 of the fixing part 100 will not be parallel to or perpendicular to the thickness direction of the first contact part 411. Similarly, the second side 102 of the fixing part 100, which is perpendicular to the first side 101, is also not parallel to or perpendicular to the thickness direction of the first contact part 411.

[0127] Similarly, in this embodiment, the amplification component 310 may have a polygonal structure (e.g., a rectangle), and when viewed along a direction perpendicular to the surface of the amplification component 310 facing the drive source 320, the extension direction of the first boundary 311 of the amplification component 310 is neither parallel to nor perpendicular to the thickness direction of the first contact portion 411, and the second boundary 312 of the amplification component 310, which is perpendicular to the first boundary 311, is also neither parallel to nor perpendicular to the thickness direction of the first contact portion 411.

[0128] Please see Figures 7 to 9C The magnetic component 700 can be accommodated in a receiving groove 240 on the movable part 200. The entrance 241 of this receiving groove 240 is formed on the side of the movable part 200, so the entrance 241 faces away from the first guide component 610. In this way, the magnetic component 700 can enter the receiving groove 240 through the entrance 241, which is beneficial for the installation of the magnetic component 700. In this embodiment, the movable part 200 also includes an opening 250, which is formed on the bottom surface 203 of the movable part 200 and communicates with the receiving groove 240, so as to allow the user to observe whether the magnetic component 700 is installed in the correct position. The width of the opening 250 can be smaller than the width of the receiving groove 240, so the magnetic component 700 will not fall out of the opening 250.

[0129] The movable part 200 also includes a protrusion 260, which protrudes from the top surface 201 of the movable part 200 and surrounds the second guide assembly 620. The upper housing 120 of the fixed part 100 may include a groove 124 corresponding to the protrusion 260, so that at least a portion of the protrusion 260 can be accommodated in the groove 124. In particular, the protrusion 260 may have a first cutting plane 261 facing the main shaft AX, a second cutting plane 262 facing away from the main shaft AX, and a recess 263 connected to the first cutting plane 261. The first cutting plane 261 and the second cutting plane 262 have different lengths and are neither parallel nor perpendicular to each other. Through the aforementioned first cutting plane 261, second cutting plane 262 and recess 263, stray light of the optical component drive mechanism 10 can be reduced, which is beneficial to improving the optical quality of the optical component drive mechanism 10.

[0130] The movable part 200 may also include an arc-shaped cutting surface 202, which may face the support column 122 of the fixed part 100 and be spaced apart from the support column 122. This can facilitate the weight reduction and miniaturization of the optical component drive mechanism 10.

[0131] Please see Figures 2 to 5 as well as Figure 10 The circuit assembly 500 may include a circuit board 510 and multiple electronic components 520. The circuit board 510 may be disposed on the L-shaped wall 123 of the upper housing 120, and the electronic components 520 may be disposed on the circuit board 510. Specifically, the user can fill the adhesive groove 123B on the L-shaped wall 123 with adhesive and then laterally connect the circuit board 510 to the L-shaped wall 123. In this way, the circuit board 510 can be attached to the L-shaped wall 123. When the circuit board 510 is mounted on the L-shaped wall 123, the electronic components 520 can be accommodated in the recesses 123C on the L-shaped wall 123, which can facilitate the miniaturization of the optical component drive mechanism 10.

[0132] The electronic component 520 may include a sensor, and the electronic component 520 as a sensor may correspond to a sensed element 800 disposed on the movable part 200, thereby detecting the position of the movable part 200 relative to the fixed part 100. For example, the electronic component 520 as a sensor may include 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, and the sensed element 800 may include a magnet, but is not limited to these.

[0133] The circuit board 510 can be connected to the drive source 320 of the drive assembly 300 via a first lead L1 and a second lead L2. The first lead L1 has a first connection segment L11 that contacts the circuit board 510, and the second lead L2 has a second connection segment L21 that contacts the circuit board 510. The first connection segment L11 may not be parallel to the second connection segment L21 to avoid mutual interference between them due to parasitic currents.

[0134] The upper housing 120 of the fixing part 100 may include a first groove 125, a second groove 126, and a partition 127. A segment L12 of the first lead L1 may be accommodated in the first groove 125, and a segment L22 of the second lead L2 may be accommodated in the second groove 126. The partition 127 may be disposed between the first groove 125 and the second groove 126. Therefore, even if the segments L12 of the first lead L1 and L22 of the second lead L2 are parallel to each other, they will be separated by the partition 127 of the fixing part 100, thereby preventing the first lead L1 and the second lead L2 from interfering with each other due to parasitic currents.

[0135] 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.
