Of course, these embodiments are merely illustrative and should not be construed as limiting the scope of the invention. For example, the specification mentions that a first feature is formed on a second feature. This may include embodiments where the first and second feature are in direct contact, or embodiments where there are other features between the first and second feature; in other words, the first and second feature are not in direct contact.

[0086] Furthermore, repeated reference numerals or designations may be used in different embodiments. These repetitions are merely for the purpose of clearly and simply describing the invention and do not represent a specific relationship between the different embodiments and / or structures discussed. Additionally, forming, connecting to, and / or coupling to another feature component in this invention may include embodiments in which the feature components are formed in direct contact, and may also include embodiments in which additional feature components may be formed to insert into the aforementioned feature component, such that the aforementioned feature components may not be in direct contact. Furthermore, spatially related terms such as “vertical,” “above,” “up,” “below,” “bottom,” and similar terms (e.g., “downward,” “upward,” etc.) may be used to facilitate the description of the relationship between one element(s) or feature(s) in the illustrations and another element(s) or feature(s). These spatially related terms are intended to cover different orientations of the device including the feature.

[0089] Furthermore, in some embodiments of this invention, terms such as "connection" and "interconnection," unless specifically defined, may refer to two structures in direct contact, or they may refer to two structures not in direct contact, with other structures disposed between them. Moreover, these terms regarding joining and connection may also include cases where both structures are movable or both structures are fixed.

[0090] Please refer to Figures 1 to 3 , Figure 1 This is a perspective view of an optical element driving mechanism 100 according to an embodiment of the present disclosure. Figure 2 This is an exploded view of an optical element driving mechanism 100 according to an embodiment of the present disclosure, and Figure 3 This is a top view of a partial structure of an optical element driving mechanism 100 according to an embodiment of the present disclosure. The optical element driving mechanism 100 may be an optical camera module configured to carry and drive an optical element. The optical element driving mechanism 100 can be installed in various electronic devices or portable electronic devices, such as smartphones, to allow users to perform image extraction functions.

[0091] In this embodiment, the optical element driving mechanism 100 may include a fixed component FA, a movable component MA, and a driving module DM. The movable component MA is movably connected to the fixed component FA. The driving module DM is configured to drive the movable component MA to move relative to the fixed component FA.

[0092] In this embodiment, as Figure 2 As shown, the fixed component FA includes a cover 102 and a base 112, and the movable component MA may include a first movable part 108 and a second movable part 110. The first movable part 108 may include a support 1081 and an optical element 1082. In this embodiment, the optical element 1082 may serve as a light shield or a shutter, but is not limited thereto. In other embodiments, the optical element 1082 may also serve as a filter or an aperture, etc.

[0093] In this embodiment, the carrier 1081 is detachably connected to the optical element 1082, but is not limited thereto. For example, in other embodiments, the optical element 1082 may be connected to the carrier 1081 using insert molding technology. For example, the carrier 1081 may be made of a non-metallic material, such as plastic, while the optical element 1082 may be made of a metallic material.

[0094] The cover 102 is fixedly mounted on the base 112. The cover 102 can be combined with the base 112 to jointly accommodate the movable component MA and the drive module DM, and the first movable part 108 can move relative to the fixed component FA.

[0095] like Figure 2 As shown, the aforementioned cover 102 has a first opening 1021, the base 112 has a second opening 1120, and the base 112 houses a photosensitive module 150 (optical module). An external light source can travel along a main axis MX and pass through the first opening 1021 and the second opening 1120 before being received by the aforementioned photosensitive module 150 to generate a digital image signal.

[0096] Additionally, the optical element driving mechanism 100 may further include a locking component LA. When the driving module DM does not drive the first movable part 108 to move relative to the fixed component FA, the locking component LA is configured to temporarily fix the first movable part 108 relative to the fixed component FA in a first position, for example... Figure 3 The position of the locking assembly LA may include a locking attachment 1101 and a first engaging structure 1083, and the locking attachment 1101 may engage with the first engaging structure 1083 so that the first movable part 108 is fixed in a first position relative to the fixed assembly FA.

[0097] In this embodiment, the drive module DM includes a first drive component DA1 for driving the first movable part 108 to move relative to the fixed component FA along the Y-axis, so that the optical element 1082 can selectively overlap with the first opening 1021. For example, when the locking component LA does not lock the first movable part 108, the first movable part 108 can move along the Y-axis to block the first opening 1021 and the second opening 1120.

[0098] The first driving component DA1 includes a first coil CL1, a first magnetically conductive element CM1, and a first magnetic element MG1. The first magnetic element MG1 corresponds to the first coil CL1, and the first magnetically conductive element CM1 corresponds to the first coil CL1; for example, the first coil CL1 is wrapped around the first magnetically conductive element CM1. The first magnetically conductive element CM1 has a plate-like structure and is perpendicular to a second axis AX2. The second axis AX2 is parallel to the Z-axis.

[0099] The fixed assembly FA has a first receiving space AS1 configured to receive a first drive assembly DA1. The fixed assembly FA also has a guide structure 112G, such as a groove, configured to guide the movement of the first moving part 108 relative to the fixed assembly FA along the Y-axis.

[0100] Please refer to Figures 2 to 6 , Figure 4 This is a top view of a portion of the structure of an optical element driving mechanism 100 according to an embodiment of the present disclosure. Figure 5 This is a bottom view of an optical element driving mechanism 100 according to an embodiment of the present disclosure, and Figure 6This is a perspective view of a partial structure of an optical element driving mechanism 100 according to an embodiment of the present disclosure. The second movable part 110 is movable relative to the fixed component FA and the first movable part 108.

[0101] The drive module DM may further include a second drive component DA2, and the second drive component DA2 is configured to drive the second movable part 110 to move relative to the fixed component FA. The second drive component DA2 can drive the second movable part 110 to move relative to the fixed component FA in a first direction D1, and the second drive component DA2 can drive the second movable part 110 to move relative to the fixed component FA in a second direction D2.

[0102] In this embodiment, both the first direction D1 and the second direction D2 are parallel to a first axis AX1, and the first direction D1 and the second direction D2 are opposite to each other. Furthermore, in this embodiment, the optical element driving mechanism 100 may also include a pressure-applying element 105, configured to generate a first preload PF1 on the second movable part 110. The pressure-applying element 105 may be, for example, a spring, and the first preload PF1 may be an elastic force, but is not limited thereto.

[0103] It is worth noting that at least one of the first direction D1 and the second direction D2 is in the same direction as the first preload PF1. In this embodiment, the first direction D1 is in the same direction as the first preload PF1.

The second magnetic element MG2 corresponds to the second coil CL2, and the second magnetically conductive element CM2 corresponds to the second coil CL2; for example, the second coil CL2 is wrapped around the second magnetically conductive element CM2. The second magnetically conductive element CM2 has a plate-like structure and is perpendicular to a second axis AX2, while a first axis AX1 is perpendicular to the second axis AX2.

[0105] The second drive assembly DA2 may also include a guide element 131 configured to guide the movement of the second movable part 110 relative to the fixed assembly FA, ​​and the guide element 131 having an elongated structure extends along the first axis AX1.

[0106] In this embodiment, the guide element 131 is fixed to the base 112, the pressure element 105 surrounds the guide element 131, and the pressure element 105 abuts between the second movable part 110 and the base 112. The pressure element 105 may have a spiral structure, may be made of metal, and may be flexible.

[0107] like Figure 4 and Figure 5As shown, the base 112 of the fixed component FA also has a second receiving space AS2 configured to receive the second drive component DA2. The second receiving space AS2 has a second slot OG2 extending toward a third direction D3. Similarly, the first receiving space AS1 has a first slot OG1 extending toward a third direction D3. Wherein, the third direction D3 is parallel to the second axis AX2 (Z-axis).

[0108] Based on the above structural design, it is convenient for operators to install the first magnetic element CM1 and the second magnetic element CM2 onto the first slot OG1 and the second slot OG2 respectively from the bottom of the base 112, thereby increasing the ease of assembly and reducing the operation time of the process.

[0109] like Figure 4 and Figure 5 As shown, when viewed along the second axis AX2 (Z-axis), the second magnetically conductive element CM2, which has an elongated structure, extends along the first axis AX1. When viewed along the second axis AX2, the first magnetically conductive element CM1, which has an elongated structure, extends along a third axis AX3 (Y-axis).

[0110] When viewed along the second axis AX2, the first coil CL1 overlaps with at least a portion of the first magnetic element MG1. Similarly, as Figure 5 and Figure 6 As shown, when viewed along the second axis AX2, the second coil CL2 overlaps with at least a portion of the second magnetic element MG2.

[0111] Please refer to Figure 7 , Figure 7 This is a front view of a portion of the structure of an optical element driving mechanism 100 according to an embodiment of the present disclosure. Figure 7 As shown, when viewed along the third axis AX3, at least a portion of the first coil CL1 and the second coil CL2 overlap. The third axis AX3 is perpendicular to both the first axis AX1 and the second axis AX2.

[0112] When viewed along the third axis AX3, at least a portion of the first coil CL1 overlaps with at least a portion of the second magnetic element MG2. When viewed along the third axis AX3, at least a portion of the first magnetic element MG1 overlaps with at least a portion of the second magnetic element MG2. When viewed along the third axis AX3, the first magnetic element MG1 does not overlap with the second coil CL2.

[0113] When viewed along the third axis AX3, the first magnetic element MG1 overlaps with at least a portion of the pressure-applying element 105. When viewed along the third axis AX3, the first coil CL1 overlaps with at least a portion of the pressure-applying element 105. When viewed along the third axis AX3, the first magnetically conductive element CM1 does not overlap with the pressure-applying element 105.

[0114] When viewed along the third axis AX3, the second magnetic element MG2 overlaps with at least a portion of the pressure-applying element 105. When viewed along the third axis AX3, the second coil CL2 overlaps with at least a portion of the pressure-applying element 105. When viewed along the third axis AX3, the second magnetically conductive element CM2 does not overlap with the pressure-applying element 105.

[0115] Please refer to Figure 2 , Figure 3 , Figure 8 as well as Figure 9 , Figure 8 This is a top view of a first movable part 108 disengaging from the locking attachment 1101 and moving along the third axis AX3 according to an embodiment of the present disclosure. Figure 9 This is a top view of a first movable part 108 moved to a second position according to an embodiment of the present disclosure. The optical element driving mechanism 100 of the present disclosure can serve as a shutter to adjust the light entering the photosensitive module 150. That is, the locking assembly LA can lock the first movable part 108 in... Figure 3 The first position or Figure 9 The second position in the list.

[0116] In this embodiment, the locking assembly LA may include the aforementioned locking attachment 1101, the aforementioned first engaging structure 1083, and a second engaging structure 1084. The locking attachment 1101 is disposed on the second movable part 110 and may be integrally formed with the second movable part 110. When viewed along the second axis AX2, the locking attachment 1101 may have a rectangular structure, but is not limited thereto.

[0117] The first locking structure 1083 and the second locking structure 1084 are formed on the optical element 1082, and the locking accessory 1101 can be locked to the first locking structure 1083 or the second locking structure 1084.

The first locking surface BS1 is parallel to the second locking surface BS2, and the first locking surface BS1 and the second locking surface BS2 face opposite directions.

[0120] The first locking surface BS1 and the second locking surface BS2 are configured to contact each other to restrict the movement of the first movable part 108 relative to the fixed component FA. It is worth noting that, as... Figure 3 As shown, when the first locking surface BS1 contacts the second locking surface BS2, the two ends of the optical element 1082 of the first movable part 108 with the elongated structure will not directly contact the base 112 of the fixing assembly FA.

[0121] Furthermore, the first locking part also includes a third locking surface BS3 and a fourth locking surface BS4. The third locking surface BS3 is located on the first engaging structure 1083 of the first moving part 108, and the fourth locking surface BS4 is located on the locking accessory 1101 of the second moving part 110 and corresponds to the third locking surface BS3.

The fourth locking surface BS4 is not parallel to the third locking surface BS3. The third locking surface BS3 and the fourth locking surface BS4 are configured to contact each other to restrict the movement of the first moving part 108 relative to the fixed component FA.

[0123] It is worth noting that on the first axis AX1, the maximum size of the first locking surface BS1 is smaller than the maximum size of the third locking surface BS3. Similarly, when the third locking surface BS3 contacts the fourth locking surface BS4, the two ends of the optical element 1082 of the first movable part 108 will not directly contact the base 112 of the fixing assembly FA.

[0124] When it is necessary to close the first opening 1021 and the second opening 1120 to prevent light from entering the photosensitive module 150, the second coil CL2 is energized to generate a second driving force DF2, causing the locking attachment 1101 to disengage from the first engaging structure 1083 along the second direction D2 to release the optical element 1082. Then, the first coil CL1 and the first magnetic element MG1 generate a first driving force DF1 to drive the first movable part 108 to move along the third axis AX3. Figure 8 At this position, the pressure element 105 is compressed, and the locking attachment 1101 abuts against a connecting surface CNS of the optical element 1082. Afterwards, the first movable part 108 is driven by the first driving force DF1 to... Figure 9 The second position in the list.

[0125] Finally, the first coil CL1 and the second coil CL2 are de-energized, and the first pre-pressure PF1 of the pressure-applying element 105 drives the locking attachment 1101 along the first direction D1 to lock the optical element 1082 in the second position, thereby closing the first opening 1021 and the second opening 1120. The steps for opening the first opening 1021 and the second opening 1120 are similar to the steps for closing them, so they will not be described again here.

[0126] In other embodiments, when the first movable part 108 is in the first position or the second position, the second drive component DA2 can generate a third drive force DF3. The third drive force DF3 is in the same direction as the first preload PF1, but in the opposite direction to the second drive force DF2.

[0127] Based on this design, it can be further ensured that the locking accessory 1101 is securely engaged with the first engaging structure 1083 or the second engaging structure 1084, thereby avoiding the problem that the optical element 1082 will disengage from the locking accessory 1101 when the optical element drive mechanism 100 is impacted.

[0128] like Figure 9 As shown, the locking assembly LA may further include a second locking portion, corresponding to the second movable portion 110 and configured to temporarily fix the first movable portion 108 in the second position. The second locking portion may include a fifth locking surface BS5 and a sixth locking surface BS6. The fifth locking surface BS5 is located in the second engagement structure 1084 of the first movable portion 108, corresponding to the fourth locking surface BS4, and the sixth locking surface BS6 is located in the second engagement structure 1084 of the first movable portion 108, corresponding to the second locking surface BS2.

[0129] The fifth locking surface BS5 is neither parallel nor perpendicular to the third axis AX3. The fifth locking surface BS5 is parallel to the fourth locking surface BS4, and the fifth locking surface BS5 and the fourth locking surface BS4 face opposite directions.

[0130] The fifth locking surface BS5 and the fourth locking surface BS4 are configured to contact each other to limit the movement of the first moving part 108 relative to the fixed component FA. It is worth noting that, as... Figure 9 As shown, when the fifth locking surface BS5 contacts the fourth locking surface BS4, the two ends of the optical element 1082 of the first movable part 108 with the elongated structure do not directly contact the fixed component FA.

[0131] Furthermore, the sixth locking surface BS6 is not parallel to the second locking surface BS2. The sixth locking surface BS6 and the second locking surface BS2 are configured to contact each other to restrict the movement of the first moving part 108 relative to the fixed component FA.

[0132] It is worth noting that on the first axis AX1, the maximum size of the fifth locking surface BS5 is smaller than the maximum size of the sixth locking surface BS6. On the first axis AX1, the maximum size of the fifth locking surface BS5 is the same as the maximum size of the first locking surface BS1. On the first axis AX1, the maximum size of the sixth locking surface BS6 is the same as the maximum size of the third locking surface BS3.

[0133] Similarly, when the sixth locking surface BS6 contacts the second locking surface BS2, the two ends of the optical element 1082 of the first movable part 108 do not directly contact the base 112 of the fixing assembly FA. Furthermore, the locking assembly LA may also include a connecting surface CNS, located in the first movable part 108 and perpendicular to the first axis AX1. The connecting surface CNS connects the first locking surface BS1 and the fifth locking surface BS5.

[0134] Please refer to Figure 10 , Figure 10 This is a perspective view of an optical element driving mechanism 100 according to an embodiment of the present disclosure from another angle. Figure 10 As shown, when the second movable part 110 is in the first position relative to the fixed component FA, and when viewed along the third axis AX3, the connecting surface CNS overlaps with at least a portion of the locking attachment 1101 of the second movable part 110.

[0135] Furthermore, when the second movable part 110 is in the first position relative to the fixed component FA, and when viewed along the third axis AX3, the connecting surface CNS overlaps with at least a portion of the second locking surface BS2.

[0136] Next, please refer to Figure 11 , Figure 11 For the optical element driving mechanism 100 according to an embodiment of the present disclosure along Figure 1 A three-dimensional cross-sectional view of the midline segment AA. The optical element drive mechanism 100 may also include a limiting component configured to limit the second movable part 110 from rotating relative to the base 112 of the fixed component FA about the first axis AX1 (X-axis).

[0137] like Figure 11 As shown, the limiting component may include a first limiting surface RS1 and a second limiting surface RS2, located on the fixing component FA and facing opposite directions. Figure 11 As shown, when viewed along the second direction D2, the first limiting surface RS1 and the second limiting surface RS2 are located on both sides of the second movable part 110. Both the first limiting surface RS1 and the second limiting surface RS2 are perpendicular to the third axis AX3.

[0138] This disclosure provides an optical element driving mechanism, including a first movable part, a fixed component, a first driving component, and a locking component. The first movable part is movable relative to the fixed component. The first driving component is configured to drive the first movable part to move relative to the fixed component. The locking component is used to position the first movable part relative to the fixed component in a first position or a second position.

[0139] In some embodiments, the locking assembly LA includes a locking attachment 1101 configured to selectively engage with a first engaging structure 1083 or a second engaging structure 1084 to lock the optical element 1082. Based on this structural design, the optical element 1082 can be securely locked. When the optical element drive mechanism is subjected to impact, the locking attachment 1101 can be effectively prevented from disengaging from the optical element 1082.

[0140] Furthermore, the optical element drive mechanism can be miniaturized through a special spatial configuration. Moreover, the fourth locking surface BS4 on the locking accessory 1101 and the fifth locking surface BS5 of the optical element 1082 can be parallel bevels to form a mutually engaging structure. This special configuration further ensures that the first opening 1021 can continue to be shielded even when the optical element drive mechanism is subjected to a strong impact.
