[0090] Figure 1 This diagram shows a perspective view of an optical element driving mechanism 100 according to some embodiments of the present invention. It should be noted that the optical element driving mechanism 100 can be disposed in any suitable electronic device, such as a mobile phone, laptop computer, etc., but the present invention is not limited thereto. In some embodiments, only a portion of the optical element driving mechanism 100 is shown, and any optical element driving mechanism that may include this portion is covered within the scope of the present invention. Figure 1 As shown, the optical element driving mechanism 100 includes a fixed part F, a first movable part 130, and a driving assembly 150 (see reference). Figure 2In some embodiments, the fixing part F may include an outer frame 110 and a base 120. A first movable part 130 is used to connect an optical element (not shown), and the first movable part 130 is movable relative to the fixing part F. For example, light may be incident into the optical element through an opening in the outer frame 110 in a direction generally parallel to the central axis C of the first movable part 130. However, the present invention is not limited thereto.

[0091] In some embodiments, the outer frame 110 may include a top surface 111 and sidewalls 112 substantially perpendicular to the top surface 111. For example, the normal direction of the top surface 111 may be substantially parallel to the central axis C (or Z-axis), and the sidewalls 112 may extend toward the base 120 and along the central axis C (or Z-axis). Furthermore, in some embodiments, the optical element drive mechanism 100 includes a plurality of buffers 195 disposed on the top surface 111 of the outer frame 110. Specifically, the buffers 195 may be made of, for example, a damping material, thereby reducing the impact of external forces on the optical element drive mechanism 100 and thus protecting the internal components of the optical element drive mechanism 100. In some embodiments, four buffers 195 may be equidistantly disposed on the top surface 111 around an opening in the top surface 111. However, the present invention is not limited thereto. In other embodiments, more or fewer buffers 195 may be provided.

[0092] Figure 2 An exploded view of an optical element driving mechanism 100 according to some embodiments of the present invention is shown. Figure 2 As shown, the first movable part 130 and the second movable part 140 are disposed in the space between the outer frame 110 and the base 120. Specifically, the second movable part 140 is disposed on the base 120, and the first movable part 130 is connected to the second movable part 140 and located between the base 120 and the first movable part 130. In some embodiments, the second movable part 140 includes a plurality of protrusions 141 extending toward the top surface 111 of the outer frame 110. The first movable part 130 can be accommodated in the space between the protrusions 141, thereby reducing the risk of failure of the first movable part 130 due to improper displacement. In some embodiments, the drive assembly 150 can drive the first movable part 130 and / or the second movable part 140 to move relative to the fixed part F (i.e., the outer frame 110 and the base 120). Specifically, the first movable part 130 is connected to the second movable part 140 via a first support assembly 170, and the second movable part 140 is connected to the base 120 via a second support assembly 180. In some embodiments, the drive assembly 150 includes a first drive element 1521, a second drive element 1522, a drive element 154, a magnetic element 155, a magnetic element 161, and a magnetic element 163 to drive the first movable part 130 to move in a horizontal direction (e.g., the XY plane) and drive the second movable part 140 to move in a vertical direction (e.g., the Z-axis).

[0093] In some embodiments, a first driving element 1521 and a second driving element 1522 are provided on the circuit board 151. The first driving element 1521 and the second driving element 1522 are, for example, coils, to generate driving force with corresponding magnetic elements 161 and 163. Specifically, the first driving element 1521, the second driving element 1522, and the corresponding magnetic elements 161 and 163 can be used to drive the first movable part 130 to move horizontally (e.g., in the XY plane) relative to the fixed part F via the first support assembly 170, while the driving element 154 and the magnetic element 155 can be used to drive the second movable part 140 to move vertically (e.g., along the Z-axis) relative to the fixed part F via the second support assembly 180. However, the present invention is not limited thereto.

[0094] Furthermore, the optical element driving mechanism 100 also includes a stabilizing component 160, which brings the first movable part 130 closer to the fixed part F (e.g., base 120). In some embodiments, the stabilizing component 160 includes a first stabilizing element 161 (magnetic element), a second stabilizing element 162, a third stabilizing element 163 (magnetic element), and a fourth stabilizing element 164. The second stabilizing element 162 corresponds to the first stabilizing element 161 (e.g., located directly below the first stabilizing element 161). Specifically, the second stabilizing element 162 may be a magnetic sheet, thereby generating a first stabilizing force (e.g., magnetic attraction) with the first stabilizing element 161. Similarly, the fourth stabilizing element 164 corresponds to the third stabilizing element 163 (e.g., located directly below the third stabilizing element 163). Specifically, the fourth stabilizing element 164 can be a magnetic sheet, thereby generating a second stabilizing force (e.g., magnetic attraction) with the third stabilizing element 163. Through the arrangement of the stabilizing component 160, the first movable part 130 can be moved towards the fixed part F, thereby controlling the first movable part 130 within the required position range when no power is applied, thereby improving the stability of the optical element drive mechanism 100.

[0095] In some embodiments, the first stabilizing element 161 and the third stabilizing element 163 may be disposed on the first movable portion 130, thereby fixing the positions of the first stabilizing element 161 and the third stabilizing element 163 within the optical element driving mechanism 100. In some embodiments, the first stabilizing element 161, the third stabilizing element 163, and the first movable portion 130 may be manufactured by injection molding, such that the first stabilizing element 161 and the third stabilizing element 163 are embedded in the first movable portion 130. However, the present invention is not limited thereto. For example, the first movable portion 130 may be made of resin material and is at least partially located between the first stabilizing element 161 and the second stabilizing element 162, and between the third stabilizing element 163 and the fourth stabilizing element 164. In this way, the first movable portion 130 will not interfere with the magnetic force (i.e., stabilizing force) generated by the first stabilizing element 161 and the second stabilizing element 162 (and the third stabilizing element 163 and the fourth stabilizing element 164). In some embodiments, a magnetic element 155 is disposed on the second movable portion 140. For example, the second movable part 140 may be made of resin. In this way, the second movable part 140 will not interfere with the driving force generated by the drive element 154 and the magnetic element 155.

[0096] Figure 3 A perspective view of the internal structure of an optical element driving mechanism 100 according to some embodiments of the present invention is shown. It should be understood that the outer frame 110 is not shown in this embodiment to clearly illustrate the internal structure of the optical element driving mechanism 100. Figure 3 As shown, the optical element driving mechanism 100 includes a fastener 190 disposed above the first movable portion 130. Specifically, the fastener 190 helps to hold the first movable portion 130 in position, thereby reducing the risk of displacement and failure of the first movable portion 130 when the optical element driving mechanism 100 is subjected to external impact. In some embodiments, the fastener 190 may at least partially overlap with the first movable portion 130 in a direction generally parallel to the Z-axis (or central axis C). However, the present invention is not limited thereto. In other embodiments, the fastener 190 may at least partially overlap with the first movable portion 130 in other directions (e.g., a direction forming an acute angle with the Z-axis (or central axis C). Additionally, in some embodiments, the second movable portion 140 includes at least one stop 142 extending from the protrusion 141 toward the top surface 111 of the outer frame 110. For example, in a plane perpendicular to the central axis C, the area of ​​the stop 142 is smaller than the area of ​​the protrusion 141. In some embodiments, the stop 142 is disposed on the edge of the protrusion 141. In some embodiments, the stop 142 overlaps with the fastener 190 in a direction perpendicular to the central axis C (e.g., the XY plane). This facilitates controlling the movement of the second movable part 140 within the desired position range, thereby improving the stability of the optical element drive mechanism 100.

[0097] Figure 4 A perspective view of the internal structure of an optical element driving mechanism 100 according to some embodiments of the present invention is shown. It should be understood that, in order to further illustrate the internal structure of the optical element driving mechanism 100, this embodiment is compared to... Figure 3 Fastener 190 was not shown either. Figure 4 As shown, circuit board 151 may be C-shaped and located around the central axis C. In some embodiments, the opening of circuit board 151 may be configured to face circuit board 155. Circuit board 151 may be configured to connect fastener 190, such that the first movable part 130 is movable. In some embodiments, the optical element driving mechanism 100 may include a plurality of wiring portions 125 electrically connected to electrical contacts 121 of base 120 and electrical contacts 1511 of circuit board 151. This improves the circuit design flexibility of the optical element driving mechanism 100. In some embodiments, a conductive structure (not shown), such as solder, may be provided between wiring portions 125 and electrical contacts 121 (or electrical contacts 1511) to ensure electrical connection between wiring portions 125 and electrical contacts 121 (or electrical contacts 1511). Furthermore, the connecting portion 125 may include multiple segments extending in different directions, thereby improving the structural strength of the connecting portion 125 and reducing the risk of failure of the optical element drive mechanism 100 due to breakage of the connecting portion 125.

[0098] Figure 5 A perspective view of the internal structure of an optical element driving mechanism 100 according to some embodiments of the present invention is shown. It should be understood that, in order to further illustrate the internal structure of the optical element driving mechanism 100, this embodiment is compared to... Figure 4 Circuit board 151 is not shown either. For example... Figure 5 As shown, the first driving element 1521 and the second driving element 1522 can be disposed on the circuit board 151, and respectively correspond to the first stabilizing element 161 and the third stabilizing element 163 (see, for example, reference). Figure 2 In some embodiments, the first driving element 1521 and the second driving element 1522 may each be a dumbbell-shaped coil, and the position sensing element 158 ​​and the electronic component 159 may be disposed within the space inside the first driving element 1521 and the second driving element 1522, thereby reducing the risk of damage to the position sensing element 158 ​​and the electronic component 159 due to external forces. In some embodiments, the position sensing element 158 ​​and the electronic component 159 may be disposed on opposite sides of the first driving element 1521 (or the second driving element 1522). For example, the position sensing element 158 ​​may be used to sense the position of the first movable part 130 relative to the fixed part F, and the electronic component 159 may be used to assist the operation of the position sensing element 158 ​​and the first driving element 1521 (or the second driving element 1522). However, the present invention is not limited thereto.

[0099] Figure 6 A perspective view of the internal structure of an optical element driving mechanism 100 according to some embodiments of the present invention is shown. It should be understood that, in order to further illustrate the internal structure of the optical element driving mechanism 100, this embodiment is compared to... Figure 5 The base 120, the first movable part 130, the circuit board 153, and the magnetic component 155 are not shown. Figure 6 As shown, the first support component 170 includes a body 171, which is disposed in the first movable part 130 (see, for example, reference). Figure 5 The body 171 extends between the first stabilizing element 161 and the second stabilizing element 140, and in a direction generally perpendicular to the central axis C (e.g., the XY plane). The body 171 can move relative to the fixed part F and the first movable part 130 via the intermediate element 172, and the body 171 is at least partially located between the first stabilizing element 161 and the second stabilizing element 162. In some embodiments, the body 171 is made of metal to provide sufficient mechanical strength. However, the present invention is not limited thereto. In some embodiments, the magnetic permeability of the body 171 is less than that of the first stabilizing element 161 (or the third stabilizing element 163), and the magnetic permeability of the body 171 is less than that of the second stabilizing element 162 (or the fourth stabilizing element 164). In this way, the body 171 will not interfere with the magnetic force (i.e., stabilizing force) generated by the first stabilizing element 161 and the second stabilizing element 162 (or the third stabilizing element 163 and the fourth stabilizing element 164). Figure 6 As shown, the first support assembly 170 further includes an intermediate element 172 disposed on the body 171. In some embodiments, the intermediate element 172 may be a ball bearing, a contact block, etc. However, the present invention is not limited thereto. In some embodiments, the body 171 and the intermediate element 172 have an integrally formed structure.

[0100] In addition, such as Figure 6 As shown, the first stabilizing element 161 further includes a first surface (e.g., the lower surface) facing the second stabilizing element 162 and a second surface (e.g., the upper surface) facing the first driving element 1521 of the driving assembly 150, and the first and second surfaces face different directions (e.g., opposite directions). Additionally, the second support assembly 180 includes at least one intermediate element 181, which is disposed between the second movable portion 140 and the base 120. The intermediate element 181 is movable relative to the fixed portion F and the second movable portion 140, wherein the intermediate element 181 and the stabilizing assembly 160 (e.g., the first stabilizing element 161, the third stabilizing element 163, etc.) are located on different sides of the optical element driving mechanism 100. For example, the intermediate element 181 may be disposed on the protrusion 141 of the second movable portion 140, and the intermediate element 181 may include different sizes (e.g., diameters). However, the present invention is not limited thereto.

[0101] In addition, such as Figure 6 As shown, the shortest distance between the driving element 154 and the second stabilizing element 162 is different from the shortest distance between the driving element 154 and the third stabilizing element 163. Specifically, the shortest distance between the driving element 154 and the second stabilizing element 162 is less than the shortest distance between the driving element 154 and the third stabilizing element 163. In some embodiments, when viewed along a horizontal direction (e.g., the X-axis), the driving element 154 and the second stabilizing element 162 at least partially overlap.

[0102] Figure 7 A perspective view of the internal structure of an optical element driving mechanism 100 according to some embodiments of the present invention. It should be understood that, in order to further illustrate the internal structure of the optical element driving mechanism 100, this embodiment is compared to... Figure 6 The first support component 170 and the second support component 180 are not shown either. For example... Figure 7 As shown, a plurality of first grooves 143 are provided on the second movable portion 140, corresponding to the intermediate element 172 of the first support assembly 170. For example, the first grooves 143 may be provided to partially accommodate the intermediate element 172. Furthermore, a plurality of second grooves 144 are provided on the protrusions 141 of the second movable portion 140, and corresponding to the intermediate element 181 of the second support assembly 180. In some embodiments, the extending direction of the first grooves 143 is different from the extending direction of the second grooves 144. For example, the extending direction of the first grooves 143 is perpendicular to the extending direction of the second grooves 144.

[0103] Figure 8 A bottom view of a stabilizing component 160 according to some embodiments of the present invention is shown. Figure 8 As shown, a plurality of first grooves 133 are provided on the first movable portion 130, corresponding to the intermediate element 172 of the first support assembly 170. For example, the first grooves 133 may be provided to partially accommodate the intermediate element 172. In some embodiments, when viewed along a direction parallel to the Z-axis (e.g., the central axis C), the first grooves 133 and the first grooves 143 at least partially overlap.

[0104] Furthermore, in some embodiments, when viewed along a direction parallel to the Z-axis (e.g., the central axis C), the first stabilizing element 161 and the second stabilizing element 162 overlap, and the dimensions of the first stabilizing element 161 and the second stabilizing element 162 are different in the same plane (e.g., the XY plane). For example, the size of the first stabilizing element 161 is larger than the size of the second stabilizing element 162. Specifically, in a plane perpendicular to the Z-axis (e.g., the XY plane), all or part of the projected area of ​​the second stabilizing element 162 lies within the projected area of ​​the first stabilizing element 161. In this embodiment, at least three-quarters of the projected area of ​​the second stabilizing element 162 may lie within the projected area of ​​the first stabilizing element 161, but this is not limited to this. In some embodiments, when viewed along a direction parallel to the Z-axis (e.g., the central axis C), the geometric center 161C of the first stabilizing element 161 does not overlap with the geometric center 162C of the second stabilizing element 162. In other words, the geometric center 162C of the second stabilizing element 162 is offset from the geometric center 161C of the first stabilizing element 161. Figure 8 As shown, when the first movable part 130 is located at the center of the movable range in the X-axis direction (for example, it can be referred to as the first movable range), when viewed along the Z-axis direction, in the X-axis direction, the geometric center 161C of the first stabilizing element 161 is closer to the outer shell 110 of the fixed part F (that is, farther away from the central axis C) than the geometric center 162C of the second stabilizing element 162.

[0105] In some embodiments, such as Figure 8 As shown, when the first movable part 130 is located at the center of its movable range in the X-axis direction (e.g., referred to as the first movable range), viewed along the Z-axis direction, the geometric center 161C of the first stabilizing element 161 and the geometric center 162C of the second stabilizing element 162 have a first distance G1 in the X-axis direction. Furthermore, when the first movable part 130 is located at the center of its movable range in the Y-axis direction (e.g., referred to as the second movable range), viewed along the Z-axis direction, the geometric center 161C of the first stabilizing element 161 and the geometric center 162C of the second stabilizing element 162 have a second distance G2 in the Y-axis direction. In some embodiments, the first distance G1 is different from the second distance G2. For example, the first distance G1 is smaller than the second distance G2. In some embodiments, the second distance G2 is larger than the movable range of the first movable part 130 in the X-axis direction (i.e., the first movable range). For example, the ratio of the movable range of the first movable part 130 in the X-axis direction (i.e., the first movable range) to the first distance G1 is at least greater than 3.

[0106] Similarly, in some embodiments, when viewed along a direction parallel to the Z-axis (e.g., the central axis C), the third stabilizing element 163 overlaps with the fourth stabilizing element 164, and the dimensions of the third stabilizing element 163 and the fourth stabilizing element 164 are not the same in the same plane (e.g., the XY plane). For example, the size of the third stabilizing element 163 is larger than the size of the fourth stabilizing element 164. Specifically, in a plane perpendicular to the Z-axis (e.g., the XY plane), all or part of the projected area of ​​the fourth stabilizing element 164 lies within the projected area of ​​the third stabilizing element 163. In this embodiment, at least three-quarters of the projected area of ​​the fourth stabilizing element 164 may lie within the projected area of ​​the third stabilizing element 163, but this is not limited to this. In some embodiments, when viewed along a direction parallel to the Z-axis (e.g., the central axis C), the geometric center 163C of the third stabilizing element 163 does not overlap with the geometric center 164C of the fourth stabilizing element 164. In other words, the geometric center 164C of the fourth stabilizing element 164 is offset from the geometric center 163C of the third stabilizing element 163. Figure 8 As shown, when the first movable part 130 is located at the center of the movable range in the Y-axis direction (for example, it can be referred to as the second movable range), when viewed along the Z-axis direction, in the Y-axis direction, the geometric center 163C of the third stabilizing element 163 is closer to the housing 110 of the fixed part F (that is, farther away from the central axis C) than the geometric center 164C of the fourth stabilizing element 164.

[0107] When the first movable part 130 is located at the center of its movable range (i.e., the second movable range) in the Y-axis direction, viewed along the Z-axis direction, the geometric center 163C of the third stabilizing element 163 and the geometric center 164C of the fourth stabilizing element 164 have a third distance G3 in the Y-axis direction. When the first movable part 130 is located at the center of its movable range (i.e., the first movable range) in the X-axis direction, viewed along the Z-axis direction, the geometric center 163C of the third stabilizing element 163 and the geometric center 164C of the fourth stabilizing element 164 have a fourth distance G4 in the X-axis direction. In some embodiments, the fourth distance G4 is different from the first distance G1. For example, the fourth distance G4 is greater than the first distance G1. In some embodiments, the first distance G1 and the third distance G3 are the same. With the above configuration, it is helpful to adjust the distribution of the stabilizing force generated by the stabilizing component 160, which is beneficial for the driving force generated by the driving component 150 to drive the first movable part 130 to move. The following will refer to Figure 9 The relationship between the stabilizing force generated by the stabilizing component 160 and the driving force generated by the driving component 150 is further explained.

[0108] Figure 9This diagram illustrates the relationship between the intensity of the driving force D generated by the driving assembly 150 and the intensity of the stabilizing force S generated by the stabilizing assembly 160 at different locations according to some embodiments of the present invention. Figure 9 As shown, the vertical axis represents the intensity of the driving force D and the stabilizing force S, respectively, and the horizontal axis represents the position of the first movable part 130 relative to the fixed part F in the X-axis direction (e.g., the first movable range). As described above, the driving assembly 150 can drive the first movable part 130 to move relative to the fixed part F within the first movable range in the X-axis direction. For example, the first movable range includes a first limit position (e.g., defined as 0 μm) and a second limit position (e.g., defined as 600 μm), located at opposite ends of the first movable range, and the center position of the first movable range is defined as 300 μm. Figure 9 As shown, when the first movable part 130 is located at the first extreme position (e.g., 0 μm), the component of the stabilizing force S generated by the stabilizing component 160 (e.g., the first stabilizing force generated by the first stabilizing element 161 and the second stabilizing element 162) in the X-axis direction is defined as the first force; when the first movable part 130 is located at the second extreme position (e.g., 600 μm), the component of the stabilizing force S generated by the stabilizing component 160 (e.g., the first stabilizing force generated by the first stabilizing element 161 and the second stabilizing element 162) in the X-axis direction is defined as the second force; when the first movable part 130 is located at the center of the first movable range (e.g., 300 μm), the component of the stabilizing force S generated by the stabilizing component 160 (e.g., the first stabilizing force generated by the first stabilizing element 161 and the second stabilizing element 162) in the X-axis direction is defined as the third force.

[0109] In some embodiments, the intensity of the third force is greater than zero. In some embodiments, the first force and the third force are in opposite directions, while the second force and the third force are in the same direction. In some embodiments, the intensity of the first force is different from the intensity of the second force. For example, the intensity of the first force is less than the intensity of the second force, and the intensity of the third force is less than the intensity of the second force. Furthermore, when the first movable part 130 is at a first extreme position (e.g., 0 μm), a first drive signal is input to the first drive element (e.g., the first drive element 1521) to generate a first drive force; when the first movable part 130 is at a second extreme position (e.g., 600 μm), a second drive signal is input to the first drive element (e.g., the first drive element 1521) to generate a second drive force. In some embodiments, the intensity of the first drive signal and the second drive signal are the same, and the polarities of the first drive signal and the second drive signal are opposite. Figure 9 As shown, the strength of the first driving force is different from the strength of the second driving force. For example, the ratio of the strength of the second driving force to the strength of the first driving force is greater than 1.5. However, the present invention is not limited thereto.

[0110] like Figure 9 As shown, by configuring the stabilizing component 160, positions with lower stabilizing force S (e.g., the first stabilizing force generated by the first stabilizing element 161 and the second stabilizing element 162) can correspond to positions with lower driving force D (e.g., the driving force generated by the first driving element 1521 and the first stabilizing element 161) generated by the driving component 150. This reduces the burden on the driving component 150 in driving the first movable part 130, thereby reducing the risk of failure of the optical element driving mechanism 100. Furthermore, the first movable part 130 can be moved closer to the fixed part F, thereby controlling the first movable part 130 within the desired position range even without power, thus improving the stability of the optical element driving mechanism 100.

[0111] In some embodiments, the first position (e.g., within the range of 450 μm to 300 μm) and the second position (e.g., within the range of 150 μm to 0 μm) are both located within the movable range in the X-axis direction (e.g., the first dimension), and the first position is closer to the center of the first range of motion (e.g., 300 μm) than the second position. In some embodiments, when the first movable part 130 is located in the first position, the strength of the first stabilizing force S and the relative position of the first movable part 130 and the fixed part F define a first slope S1. When the first movable part 130 is located in the second position, the strength of the first stabilizing force S and the relative position of the first movable part 130 and the fixed part F define a second slope S2. Figure 9 As shown, the first slope S1 and the second slope S2 are different. For example, the value of the first slope S1 is greater than the value of the second slope S2. With the above configuration, it is beneficial to control the movement of the first moving part 130 at different rates according to the user's needs, thereby improving the efficiency of the optical element drive mechanism 100.

[0112] It should be understood that the above description is based on the example of the strength of the first stabilizing force generated by the second stabilizing element 162 and the first stabilizing element 161 in the X-axis direction and the relative position of the first moving part 130 and the fixed part F. Figure 9 The contents shown can also be applied to the relative positions of the strength of the first stabilizing force generated by the second stabilizing element 162 and the first stabilizing element 161 and the first movable part 130 and the fixed part F in the Y-axis direction, and the relative positions of the strength of the second stabilizing force generated by the stabilizing assembly 160 (i.e. the stabilizing force generated by the fifth stabilizing element 165 and the fourth stabilizing element 164) and the first movable part 130 and the fixed part F.

[0113] As described above, the drive assembly 150 can drive the first movable part 130 to move relative to the fixed part F within a second movable range in the Y-axis direction. For example, the second movable range includes a third limit position (e.g., defined as 0 μm) and a fourth limit position (e.g., defined as 600 μm), located at opposite ends of the second movable range, and the center position of the second movable range is defined as 300 μm. For example, when the first movable part 130 is in the third extreme position (e.g., 0 μm), the component of the stabilizing force S generated by the stabilizing component 160 (e.g., the first stabilizing force generated by the first stabilizing element 161 and the second stabilizing element 162) in the Y-axis direction is defined as the fourth force; when the first movable part 130 is in the fourth extreme position (e.g., 600 μm), the component of the stabilizing force S generated by the stabilizing component 160 (e.g., the first stabilizing force generated by the first stabilizing element 161 and the second stabilizing element 162) in the Y-axis direction is defined as the fifth force; when the first movable part 130 is in the center of the second movable range (e.g., 300 μm), the component of the stabilizing force S generated by the stabilizing component 160 (e.g., the first stabilizing force generated by the first stabilizing element 161 and the second stabilizing element 162) in the Y-axis direction is defined as the sixth force.

[0114] In some embodiments, the intensity of the sixth force is greater than zero. In some embodiments, the fourth force is opposite in direction to the sixth force, while the fifth force is in the same direction as the sixth force. In some embodiments, the intensity of the fourth force is different from the intensity of the fifth force. For example, the intensity of the fourth force is less than the intensity of the fifth force, and the intensity of the sixth force is less than the intensity of the fifth force. Correspondingly, when the first movable part 130 is at the third extreme position (e.g., 0 μm), the third driving signal is input to the second driving element (e.g., the second driving element 1522) to generate the third driving force; when the first movable part 130 is at the fourth extreme position (e.g., 600 μm), the fourth driving signal is input to the second driving element (e.g., the second driving element 1522) to generate the fourth driving force. In some embodiments, the intensity of the third driving signal and the fourth driving signal are the same, and the polarities of the third driving signal and the fourth driving signal are opposite. Figure 9 As shown, the strength of the third driving force differs from that of the fourth driving force. For example, the ratio of the strength of the fourth driving force to that of the third driving force is greater than 1.5. However, this invention is not limited thereto.

[0115] In some embodiments, when the first movable part 130 is at a first extreme position (e.g., 0 μm), the component of the stabilizing force S generated by the stabilizing component 160 (e.g., the second stabilizing force generated by the third stabilizing element 163 and the fourth stabilizing element 164) in the Y-axis direction is defined as the seventh force; when the first movable part 130 is at a second extreme position (e.g., 600 μm), the component of the stabilizing force S generated by the stabilizing component 160 (e.g., the second stabilizing force generated by the third stabilizing element 163 and the fourth stabilizing element 164) in the Y-axis direction is defined as the eighth force; and when the first movable part 130 is at the center of the first movable range (e.g., 300 μm), the component of the stabilizing force S generated by the stabilizing component 160 (e.g., the second stabilizing force generated by the third stabilizing element 163 and the fourth stabilizing element 164) in the Y-axis direction is defined as the ninth force.

[0116] In some embodiments, the strength of the ninth force is greater than zero. In some embodiments, the seventh force is opposite in direction to the ninth force, while the eighth force is in the same direction as the ninth force. In some embodiments, the strength of the seventh force is different from the strength of the eighth force. For example, the strength of the seventh force is less than the strength of the eighth force, and the strength of the ninth force is less than the strength of the eighth force. In some embodiments, the ratio of the sum of the strengths of the first force and the seventh force to the sum of the strengths of the second force and the eighth force is greater than 1.3. In some embodiments, the ratio of the strength of the first force to the strength of the second force is greater than 1.2. In some embodiments, the ratio of the strength of the seventh force to the strength of the eighth force is greater than 1.2. According to the above configuration, when the drive assembly 150 is not energized (i.e., not activated), the central axis C of the first movable part 130 may be offset from the geometric center of the optical element drive mechanism 100 in the horizontal direction (e.g., the X-axis or the Y-axis). For example, the central axis C of the first movable part 130 may be offset from the geometric center of the optical element drive mechanism 100 by a range of approximately 100 μm to approximately 150 μm. In some embodiments, the central axis C of the first movable portion 130 may be offset from the geometric center of the optical element drive mechanism 100 by approximately one-sixth of the length of the first movable range (or the second movable range). However, the present invention is not limited thereto.

[0117] In summary, this utility model provides an optical element driving mechanism including a stabilizing component. By incorporating the stabilizing component, the first movable part can be brought closer to the fixed part, thereby controlling the first movable part within the desired position range even without power, thus improving the stability of the optical element driving mechanism. Furthermore, the spacing and position between the geometric centers of the stabilizing elements in the stabilizing component can be adjusted to optimize the performance of the optical element driving mechanism.
