Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of optical element driving mechanism, more particularly to the optical element driving mechanism that one optical element can be driven relative to fixed department movement. BACKGROUND

[0002] With the development of technology, nowadays many electronic devices (such as notebook computers, smart phones or digital cameras) have the functions of taking pictures or recording videos. These electronic devices are increasingly popular, and in addition to developing more stable and better optical quality, they also aim for convenient and lightweight design to provide users with more choices.

[0003] The aforementioned electronic devices with the functions of taking pictures or recording videos usually include one or more lenses to achieve the functions of focusing, zooming and / or optical image stabilization (OIS). Therefore, the optical module usually includes a driving assembly that drives the movement of the optical element. However, the complex process and heavy parts of the known driving assembly often result in a large distance between the overall center of mass and the center of rotation (e.g., the fulcrum), causing tilting or deflection problems. Therefore, how to accurately adjust the position of the optical element and avoid tilting or deflection becomes an important issue. Therefore, an optical component is needed that allows adjustment of the optical photography focal length to adapt to different external photography needs. At the same time, it has a stable internal structure to provide more stable and better optical quality. SUMMARY

[0078] The utility model relates to an optical element driving mechanism, which has a driving assembly and a support assembly, the support assembly has a plurality of support elements, when the driving assembly drives the movable part and the optical element to move, the movable part moves relative to the fixed part, thereby adjusting the photographic imaging of the optical element driving mechanism to adapt to different photographic requirements.

[0079] Next, please refer to Figure 1 and Figure 2 . Figure 1 For some features according to the present application, a perspective view of an example optical element driving mechanism 1.

[0080] Figure 2 For some features according to the present application, an exploded perspective view of an example optical element driving mechanism 1.

[0081] The example optical element driving mechanism 1 includes a movable part 100, a fixed part 200, a driving assembly 300, and a support assembly 400. The movable part 100 is connected to an optical element 10. The optical element 10 can be an optical lens, such as a prism. The movable part 100 can move relative to the fixed part 200. The driving assembly 300 drives the movable part 100 to move relative to the fixed part 200. The movable part 100 can move relative to the fixed part 200 via the support assembly 400.

[0082] Incident light from the outside passes through the optical element driving mechanism 1 along an incident direction (i.e., the Z-axis direction) to reach the optical element 10. The optical element 10 is disposed on the optical element driving mechanism 1 (in the accommodation portion 110 of the movable part 100) and achieves the functions of auto focus (AF) and optical image stabilization (OIS) through the optical element driving mechanism 1.

[0083] The fixed part 200 includes a housing 210, a base 220, a frame 230, a connecting element 240, and a circuit board 250.

[0084] The housing 210 is fixedly connected to the base 220 and the frame 230. The connecting element 240 connects the fixed part 200 and the movable part 100. In this example, the connecting element 240 is a magnetic conductive plate located in the frame 230. The frame 230 can be divided into two parts 230-1 and 230-2 for assembly and fixedly attached to the base 220. The frame 230 can be attracted to the movable part 100 by the magnetic attraction of the connecting element 240. The circuit board 250 is fixedly attached to the base 220.

[0085] The driving assembly 300 includes magnetic elements 310, 330 and coils 320, 340. The magnetic elements 310, 330 are disposed on the movable part 100. The coils 320, 340 are disposed on the base 220 and the circuit board 250 fixedly attached to the base 220.

[0086] The magnetic element 310 moves relative to the coil 320 along the direction around the X-axis by the electromagnetic driving force generated between the magnetic element 310 and the coil 320. The magnetic element 330 moves relative to the coil 340 along the direction around the Y-axis by the electromagnetic driving force generated between the magnetic element 330 and the coil 340, and the magnetic attraction force generated between the magnetic element 310 and the connecting element 240 can make the frame 230 abut against the movable part 100.

[0087] Thus, the movable part 100 moves relative to the base 220, and the movable part 100 drives the movement of the optical element 10. Therefore, the movable part 100 can be driven to drive the optical element 10 to move relative to the base 220 along the direction around the X-axis and along the direction around the Y-axis by the electromagnetic driving force generated between the magnetic elements 310, 330 and the coils 320, 340.

[0088] Next, refer to Figure 2 and Figures 3 to 6 . Figure 3 For some features according to the present application, a front view of the movable part 100 and part of the support assembly 400 of the example optical element driving mechanism 1 is shown, and for the purpose of illustration, the intermediate elements 415, 435 are shown in dashed lines.

[0089] Figure 4 For some features according to the present application, a perspective view of the frame 230 and part of the support assembly 400 of the example optical element driving mechanism 1 is shown, and for the purpose of illustration, the intermediate elements 415, 435 are shown in dashed lines.

[0090] Figure 5 For some features according to the present application, a front view of the example optical element driving mechanism 1 is shown, and for the purpose of illustration, the housing 210 and the connecting element 240 are removed, and the frame 230 is shown in dashed lines.

[0091] Figure 6 For some features according to the present application, a top view of the example optical element driving mechanism 1 is shown, and for the purpose of illustration, the housing 210 is removed, and the frame 230 and the movable part 100 are shown in dashed lines.

[0092] The support assembly 400 comprises a first surface 401, a second surface 402, a third surface 403, a fourth surface 404, a fifth surface 405, a first support element 410, a first intermediate element 415, a second support element 420, a third support element 430, a second intermediate element 435, a fourth support element 440, and a first opening A1.

[0093] The first intermediate element 415 movably connects the first support element 410 and the second support element 420. The second intermediate element 435 movably connects the third support element 430 and the fourth support element 440. The first intermediate element 415 and the second intermediate element 435 are elements, such as balls, that can move between the first support element 410 and the second support element 420 and between the third support element 430 and the fourth support element 440.

[0094] The first support element 410 has a first recessed structure 412. The first recessed structure 412 is formed on the first surface 401. The first intermediate element 415 is at least partially located in the first recessed structure 412. The second support element 420 corresponds to the first intermediate element 415 and the first support element 410. The second support element 420 has a second recessed structure 422. The second recessed structure 422 is formed on the second surface 402. The first intermediate element 415 is at least partially located in the second recessed structure 422.

[0095] The third surface 403 faces the optical element 10( Figure 2 ) and is adjacent to the first surface 401. The fourth surface 404 is adjacent to the first surface 401 and faces a different direction from the third surface 403. The first opening A1 is formed on the fourth surface 404 and is adjacent to the first recessed structure 412, which extends from the first recessed structure 412.

[0096] The third support element 430 has a third recessed structure 432. The third recessed structure 432 is formed on the fifth surface 405. The second intermediate element 435 is at least partially located in the third recessed structure 422. The fourth support element 440 corresponds to the second intermediate element 435 and the third support element 430. The fourth support element 440 has a fourth recessed structure 442. The second intermediate element 435 is at least partially located in the fourth recessed structure 442.

[0097] The first recessed structure 412 is different from the second recessed structure 422. The first recessed structure 412 has a triangular pyramid hollow structure. The second recessed structure 422 and the fourth recessed structure 442 have a circular arc V-shaped structure. The third recessed structure 432 has a V-shaped structure.

[0098] The first recess structure 412 includes a first corresponding surface S1, a second corresponding surface S2, and a third corresponding surface S3. The first corresponding surface S1, the second corresponding surface S2, and the third corresponding surface S3 correspond to the first intermediate element 415. The second corresponding surface S2 is not parallel to the first corresponding surface S1. The third corresponding surface S3 is not parallel to the first corresponding surface S1 and the second corresponding surface S2. The second corresponding surface S1 is not perpendicular to the first corresponding surface S1.

[0099] The second recess structure 422 includes a first side L1, a second side L2, a third side L3, a fourth side L4, a fourth corresponding surface S4, and a fifth corresponding surface S5.

[0100] The fourth corresponding surface S4 and the fifth corresponding surface S5 correspond to the first intermediate element 415. The fifth corresponding surface S5 is not parallel to the fourth corresponding surface S4. The fourth corresponding surface S4 is not perpendicular to and not parallel to the first corresponding surface S1, the second corresponding surface S2, and the third corresponding surface S3.

[0101] The second side L2 is opposite to the first side L1. The third side L3 is between the first side L1 and the second side L2. The fourth side L4 is opposite to the third side L3 and is between the first side L1 and the second side L2. The length of the first side L1 is different from the length of the second side L2. The length of the first side L1 is smaller than the length of the second side L2. The first side L1 and the second side L2 can be formed in a curved shape, and the third side L3 and the fourth side L4 can be formed in a straight line shape. The curved shape of the first side L1 and the second side L2 is formed based on the same center, the curved shape of the first side L1 is formed based on a first radius length, the curved shape of the second side L2 is formed based on a second radius length, the first radius length is different from the second radius length, and the first radius length is smaller than the second radius length. When viewed in the direction perpendicular to the second surface 402 (viewed in the perspective of Figure 5 When viewed in the direction perpendicular to the second surface 402 (viewed in the perspective of

[0102] The first recess structure 412 and the first intermediate element 415 have the first corresponding surface S1, the second corresponding surface S2, and the third corresponding surface S3, which are a total of three contact surfaces. The second recess structure 422 and the first intermediate element 415 have the fourth corresponding surface S4 and the fifth corresponding surface S5, which are a total of two contact surfaces. Therefore, the number of contact surfaces of the first recess structure 412 and the first intermediate element 415 is greater than the number of contact surfaces of the second recess structure 422 and the first intermediate element 415.

[0103] As mentioned above, the active part 100 is driven by the electromagnetic driving force generated between the magnetic elements 310, 330 and the coils 320, 340 to move the optical element 10 relative to the base 220. The magnetic elements 310, 330 and the coils 320, 340 drive the active part 100 to move the optical element 10 relative to the base 220 in a rotational motion, and the first intermediate element 415 and the second intermediate element 435 move in a rolling motion between the active part 100 and the frame 230 fixedly attached to the base 220.

[0104] The magnetic elements 310 and the coils 320 drive the active part 100 and the optical element 10 to move in a rotational motion along the O1 axis. Due to the rolling motion of the first intermediate element 415 and the second intermediate element 435, the O1 axis is located between the first intermediate element 415 and the second intermediate element 435 and is parallel to the X axis. The O1 axis can pass through the center of the first intermediate element 415 and the second intermediate element 435, or any position between the first intermediate element 415 and the second intermediate element 435.

[0105] The magnetic elements 330 and the coils 340 drive the active part 100 and the optical element 10 to move in a rotational motion along the O2 axis. Due to the rolling motion of the first intermediate element 415 and the second intermediate element 435, the O2 axis passes through the first intermediate element 415 and the second intermediate element 435 and is parallel to the Y axis.

[0106] The driving assembly 300 can drive the active part 100 to move from a first state to a second state relative to the fixed part 200. The first state and the second state can be any two positions of the active part 100 in its maximum range of movement, for example, the first state is the starting position of the active part 100, and the second state is the ending position of the active part 100.

[0107] When the driving assembly 300 drives the active part 100 to move relative to the fixed part 200, the first intermediate element 415 rolls relative to the first recess structure 412 between the first recess structure 412 and the second recess structure 422, because the lateral movement of the first intermediate element 415 is limited by the three contact surfaces (the first corresponding surface S1, the second corresponding surface S2 and the third corresponding surface S3) of the first recess structure 412.

[0108] When viewed in the direction perpendicular to the first surface 401 (along the Z axis), the first intermediate element 415 moves in a rolling motion along the first recess structure 412 and the second recess structure 422. Figure 5viewed from the perspective of the first recessed structure 412): when the movable part 100 is in the first state, the distance between the center of the first intermediate element 415 and the center of the first recessed structure 412 is the same as the distance between the center of the first intermediate element 415 and the center of the first recessed structure 412 when the movable part 100 is in the second state. That is, when the movable part 100 moves, the first intermediate element 415 rotates in place with respect to the first recessed structure 412 without displacement in the first recessed structure 412.

[0109] Due to the V-shaped structure of the second recessed structure 422, it has two contact surfaces (the fourth corresponding surface S4 and the fifth corresponding surface S5) with the first intermediate element 415, and the lateral movement of the first intermediate element 415 is not limited by the two contact surfaces of the second recessed structure 422. Therefore, the first intermediate element 415 rolls and slides with respect to the second recessed structure 422 between the first recessed structure 412 and the second recessed structure 422.

[0110] viewed from the perspective of the second surface 402 (along the direction of the second surface 402 Figure 5 viewed from the perspective of the first recessed structure 412): when the movable part 100 is in the first state, the distance between the center of the first intermediate element 415 and the center of the second recessed structure 422 is different from the distance between the center of the first intermediate element 415 and the center of the second recessed structure 422 when the movable part 100 is in the second state. That is, when the movable part 100 moves, the first intermediate element 415 rotates and displaces with respect to the second recessed structure 422 in the second recessed structure 422.

[0111] Next, please refer to Figure 7 . Figure 7 For the purpose of illustration, the housing 210 and the connecting element 240 are removed, and the frame 230 is shown in dashed lines in the front view of another example optical element driving mechanism 1-2 according to certain features of the present disclosure.

[0112] Figure 7 The optical element driving mechanism 1-2 in Figure 5 is similar to the optical element driving mechanism 1 in , wherein the same elements are labeled with the same element symbols. It is worth noting that the third recessed structure 432-2 of the optical element driving mechanism 1-2 is a triangular pyramid recessed structure, like the first recessed structure 412, instead of the V-shaped structure of the third recessed structure 432 of the optical element driving mechanism 1. The recessed structures accommodating the first intermediate element 415 and the second intermediate element 435 can be configured as desired.

[0121] Incident light from the outside passes through the optical element drive mechanism 1' along an incident direction (i.e., the Z-axis direction) and reaches the optical element 10. The optical element 10 is mounted on the optical element drive mechanism 1' and achieves the functions of autofocus and optical image stabilization through the optical element drive mechanism 1'.

[0122] The fixing part 200' includes a housing 210', a frame 230', a connecting element 240', and a circuit board 250.

[0123] The housing 210' is fixedly connected to the frame 230'. A connecting element 240' connects the fixed portion 200' to the movable portion 100'. In this example, the connecting element 240' is a spring, fixedly connected to the fixed portion 200' and the movable portion 100'. For example, the connecting element 240' can be fixedly connected to the center of the movable portion 100' and to the side of the frame 230', thereby connecting the fixed portion 200' and the movable portion 100'. The frame 230' can be attracted to the movable portion 100' by the pulling force of the connecting element 240'. The circuit board 250 is fixedly attached to the frame 230'.

[0124] The drive assembly 300 includes magnetic elements 310 and 330 and coils 320 and 340. Magnetic elements 310 and 330 are disposed in the movable part 100'. Coils 320 and 340 are disposed in the frame 230' and the circuit board 250.

[0125] The magnetic element 310 moves relative to the coil 320 along the X-axis due to the electromagnetic driving force generated between the magnetic element 310 and the coil 320. The magnetic element 330 moves relative to the coil 340 along the Y-axis due to the electromagnetic driving force generated between the magnetic element 330 and the coil 340.

[0126] As a result, the movable part 100' moves relative to the frame 230', and the movable part 100' drives the optical element 10 to move. Therefore, the electromagnetic driving force generated between the magnetic elements 310, 330 and the coils 320, 340 can drive the movable part 100' to move the optical element 10 relative to the frame 230' in the X-axis direction and in the Y-axis direction.

[0127] The support assembly 400' includes a first surface 401', a second surface 402', a fifth surface 405', a first support element 410', a first intermediate element 415, a second support element 420', a third support element 430', a second intermediate element 435', and a fourth support element 440'.

[0128] The first intermediate element 415 is movably connected to the first support element 410' and the second support element 420'. The second intermediate element 435 is movably connected to the third support element 430' and the fourth support element 440'. The first intermediate element 415 and the second intermediate element 435 are movable between the first support element 410' and the second support element 420', and between the third support element 430' and the fourth support element 440'.

[0129] The first support element 410' has a first recessed structure 412'. The first recessed structure 412' is formed on the first surface 401'. The first intermediate element 415 is at least partially located in the first recessed structure 412'. The second support element 420' corresponds to the first intermediate element 415 and the first support element 410'. The second support element 420' has a second recessed structure 422'. The second recessed structure 422' is formed on the second surface 402'. The first intermediate element 415 is at least partially located in the second recessed structure 422'.

[0130] The third support element 430' has a third recessed structure 432'. The third recessed structure 432' is formed on the fifth surface 405'. The second intermediate element 435 is at least partially located in the third recessed structure 432'. The fourth support element 440' corresponds to the second intermediate element 435 and the third support element 430'. The fourth support element 440 has a fourth recessed structure 442'. The second intermediate element 435 is at least partially located in the fourth recessed structure 442'.

[0131] The first recessed structure 412' differs from the second recessed structure 422'. The first recessed structure 412' has a triangular pyramidal hollow structure. The second recessed structure 422' and the fourth recessed structure 442' have an arc-shaped V-shaped structure. The third recessed structure 432' has a V-shaped structure.

[0132] The first recessed structure 412' and the first intermediate element 415 have a total of three contact surfaces. The second recessed structure 422' and the first intermediate element 415 have a total of two contact surfaces. Therefore, the number of contact surfaces between the first recessed structure 412' and the first intermediate element 415 is greater than the number of contact surfaces between the second recessed structure 422' and the first intermediate element 415.

[0133] As described above, the electromagnetic driving force generated between the magnetic elements 310, 330 and the coils 320, 340 drives the movable part 100' to move the optical element 10 relative to the frame 230'. The magnetic elements 310, 330 and the coils 320, 340 drive the movable part 100' to rotate the optical element 10 relative to the base 220, and the first intermediate element 415 and the second intermediate element 435 roll between the movable part 100' and the frame 230'.

[0134] The drive assembly 300 can drive the movable part 100' from a first state to a second state relative to the fixed part 200'. The first state and the second state can be any two positions of the movable part 100' in its maximum range of movement, for example, the first state is the movable part 100' in its starting position of movement, and the second state is the movable part 100' in its ending position of movement.

[0135] When the drive assembly 300 drives the movable part 100' to move relative to the fixed part 200', the first intermediate element 415 rolls relative to the first recessed structure 412' between the first recessed structure 412' and the second recessed structure 422' because the lateral movement of the first intermediate element 415 is limited by the three contact surfaces of the first recessed structure 412'.

[0136] When viewed along the direction perpendicular to the first surface 401' (along the view direction of Figure 12 ): when the movable part 100' is in the first state, the distance between the center of the first intermediate element 415 and the center of the first recessed structure 412' is the same as the distance between the center of the first intermediate element 415 and the center of the first recessed structure 412' when the movable part 100' is in the second state. That is, when the movable part 100' moves, the first intermediate element 415 rotates in place relative to the first recessed structure 412' without displacement in the first recessed structure 412'.

[0137] Because of the V-shaped structure of the second recessed structure 422', it has two contact surfaces with the first intermediate element 415, and the lateral movement of the first intermediate element 415 is not limited by the two contact surfaces of the second recessed structure 422'. Therefore, the first intermediate element 415 rolls and slides relative to the second recessed structure 422' between the first recessed structure 412' and the second recessed structure 422'.

[0138] When viewed along the direction perpendicular to the second surface 402' (along the view direction of Figure 12 ): when the movable part 100' is in the first state, the distance between the center of the first intermediate element 415 and the center of the second recessed structure 422' is different from the distance between the center of the first intermediate element 415 and the center of the second recessed structure 422' when the movable part 100' is in the second state. That is, when the movable part 100' moves, the first intermediate element 415 rotates and displaces relative to the second recessed structure 422' in the second recessed structure 422'.

[0139] Next, please refer to Figure 13 . Figure 13For the purpose of illustration, the housing 210' is removed and the movable portion 100' is shown in dashed lines. The optical element driving mechanism 1-2' is similar to the optical element driving mechanism 1' in
