[0064] The present disclosure relates to an optical element driving mechanism, wherein a driving component of the optical element driving mechanism has a coil and a magnetic element, which drives a movable part and an optical element to move, thereby adjusting the photographic imaging of the optical element driving mechanism.

[0065] First please see Figure 1 , Figure 1 1 is a front perspective view of an optical element driving mechanism 1 according to certain features of the present disclosure.

[0066] See also Figure 2 . Figure 2The optical element driving mechanism 1 is an exploded perspective view according to certain features of the present disclosure. The optical element driving mechanism 1 includes a movable portion 100, a fixed portion 200, a driving assembly 300, a positioning assembly 400, a guiding assembly 500, a sensing assembly 600, a protection assembly 700, a first connecting element 800 (shown in FIG.

[0067] The movable part 100 is connected to an optical element (not shown), and the optical element can be, for example, an optical lens. The movable part 100 can move relative to the fixed part 200, and the driving component 300 drives the movable part 100 to move relative to the fixed part 200. The positioning component 400 is fixedly connected to the fixed part 200. The protection component 700 corresponds to the driving component 300. The movable part 100 can move relative to the fixed part 200 via the guide component 500. The sensing component 600 senses the movement of the movable part 100. The circuit component 900 is electrically connected to the driving component 300.

[0068] The driving assembly 300 includes a coil 310 , a plurality of magnetic elements 320 , and a plurality of magnetic conductive plates 330 . In this embodiment, the driving assembly 300 includes four magnetic elements 320 and four magnetic conductive plates 330 . The coil 310 is fixedly located on the positioning assembly 400 . The magnetic element 320 is fixedly located on the movable portion 100 .

[0069] The electromagnetic driving force generated between the magnetic element 320 and the coil 310 causes the magnetic element 320 to move relative to the coil 310, thereby driving the movable part 100 to move relative to the positioning assembly 400. Therefore, the electromagnetic driving force generated between the magnetic element 320 and the coil 310 causes the movable part 100 to move relative to the fixed part 200.

[0070] The four magnetic conductive plates 330 are respectively fixedly connected to the magnetic elements 320 of the driving assembly 300 to prevent magnetic field interference between multiple groups of magnetic elements 320 .

[0071] The coil 310 includes a plurality of first portions 311 and a plurality of second portions 312. The first portions 311 and the second portions 312 are both located on the same side of the coil 310. The first portion 311 is closer to the support portion 450 of the positioning assembly 400 than the second portion 312. The first portion 311 and the second portion 312 will be described below relative to each other. Figure 5 Describe in more detail.

[0072] The positioning assembly 400 positions the coil 310. The positioning assembly 400 includes a plurality of side walls 410, 420, 430, 440, a plurality of hollow portions 415, 425, 435, 445 (see Figure 3), a plurality of support parts 450, 460, 470, 480, a bottom plate 490, and a first axis O1 and a second axis O2. The coil 310 is positioned on the side walls 410, 420, 430, 440. The support parts 450, 460, 470, 480 are fixedly connected to the side walls 410, 420, 430, 440. The side walls 410, 420, 430, 440 are fixedly positioned on and connected to the bottom plate 490. The second axis O2 is perpendicular to the first axis O1.

[0073] Please refer to the following Figure 2 , Figure 3 ,as well as Figure 4 . Figure 3 1 is a front perspective view of a positioning assembly 400 of an optical element driving mechanism 1 according to certain features of the present disclosure. Figure 4 According to certain features of the present disclosure, the optical element driving mechanism 1 is arranged along Figure 1 FIG. 2 is a partial cross-sectional enlarged view of line AA of FIG. 1 , wherein the fixing portion 200 is removed for illustrative purposes. Figure 4 Only one set of sidewalls 410 and support portions 450 is shown, and other sets of sidewalls and support portions may also have the features described below.

[0074] The side walls 410, 420, 430, 440 respectively have a first surface 410a, 420a, 430a, 440a, a second surface 410b, 420b, 430b, 440b, and a third surface 410c, 420c, 430c, 440c ( Figure 4 Only the first surface 410a, the second surface 410b, and the third surface 410c are shown).

[0075] The first surfaces 410a, 420a, 430a, 440a face the coil 310, and the second surfaces 410b, 420b, 430b, 440b face the magnetic element 320. The second surfaces 410b, 420b, 430b, 440b are not parallel to the respective first surfaces 410a, 420a, 430a, 440a. The third surfaces 410c, 420c, 430c, 440c face directions different from the respective first surfaces 410a, 420a, 430a, 440a and the second surfaces 410b, 420b, 430b, 440b.

[0076] The first axis O1 is parallel to the first surface 410a. On the first axis O1, the shortest distance d1 between the coil 310 and the magnetic element 320 is greater than the shortest distance d2 between the second surface 410b and the magnetic element 320. In other words, the second surface 410b is closer to the magnetic element 320 than the coil 310. On the first axis O1, a maximum dimension w1 of the support portion 450 is greater than a maximum dimension w2 of the side wall 410.

[0077] The second axis O2 is parallel to the second surface 410b. The side walls 410, 420, 430, 440 each have two parts, the heights of the two parts are respectively h1 and h2, and there is a hollow part 415, 425, 435, 445 in the middle of the two parts (see Figure 3 ) to accommodate the coil 310, Figure 4 A hollow portion 415 between two portions of the side wall 410 is shown to accommodate the coil 310 .

[0078] The support portion 450 has a height h3. On the second axis O2, the height h3 is approximately equal to the sum of the two heights h1 and h2 of the side wall 410 and the height of the hollow portion. Therefore, the sum of the two heights h1 and h2 of the side wall 410 is less than the height h3 of the support portion 450, and the maximum dimension height h3 of the support portion 450 is greater than the maximum dimension of the sum of the two heights h1 and h2 of the side wall 410.

[0079] See you next Figure 5 . Figure 5 According to certain features of the present disclosure, a partially enlarged top view of the optical element driving mechanism 1 is shown, wherein for illustrative purposes, the fixed portion 200 is removed, and the movable portion 100 and the positioning assembly 400 are shown in dotted lines. Figure 5 Only one set of the first portion 311 , the second portion 312 , and the magnetic element 320 is shown, and the other first portions 311 , the second portions 312 , and the magnetic element 320 may also have the following features.

[0080] When viewed along a second axis O2 of the positioning assembly 400 , the first portion 311 of the coil 310 is closer to the support portion 450 than the second portion 312 .

[0081] On the first axis O1, the shortest distance d3 between the first portion 311 and the magnetic element 320 is greater than the shortest distance d4 between the second portion 312 and the magnetic element 320. The shortest distance d3 and the shortest distance d4 have a difference value, which is at least greater than 0.008 mm. The difference value is greater than a size of a cross section of a lead wire constituting the coil 310.

[0082] Please continue to refer to Figure 2 The guide assembly 500 has a plurality of guide elements 510, 520 and respective corresponding portions 530, 540. The guide elements 510, 520 are disposed on the support portions 450, 470. The corresponding portions 530, 540 are formed on the movable portion 100. The corresponding portions 530, 540 correspond to the guide elements 510, 520 and can move relative to the guide elements 510, 520.

[0083] In this embodiment, the corresponding portion 530 has a plane, and the corresponding portion 540 has a V-shaped groove, respectively contacting the guide elements 510, 520. They can be any shape suitable for the guide elements 510, 520.

[0084] When the magnetic element 320 moves relative to the coil 310 and drives the movable part 100 to move relative to the positioning assembly 400 , the guide elements 510 , 520 make the movement stable and prevent overturning.

[0085] The sensing component 600 is at least partially disposed on the supporting portion 470. The guiding element 520 and the sensing component 600 are respectively disposed on different surfaces of the supporting portion 470, and the two different surfaces face different directions.

[0086] The protection assembly 700 includes a plurality of protection elements 710, 720, which are disposed on the third surfaces 410c, 420c. The height h4 of the protection elements 710, 720 is greater than the range of motion of the movable portion 100. The height h4 of the protection elements 710, 720 is greater than the height h3 of the support portion 450 (see Figure 4 ). The protection elements 710 and 720 may be magnetic conductive plates. In this embodiment, the protection elements 710 and 720 are approximately in a cross shape. In other embodiments, the protection elements 710 and 720 may be in any shape that effectively prevents magnetic field interference when the movable part 100 moves.

[0087] Please refer to the following Figure 6 . Figure 6 An enlarged top view of the optical element driving mechanism 1 according to certain features of the present disclosure, wherein for illustrative purposes, the fixed portion 200 is removed, and the movable portion 100 and the positioning assembly 400 are shown in dotted lines.

[0088] The protection elements 710 and 720 are disposed on the third surfaces 410 c and 420 c , and the magnetic adsorption forces F1 and F2 thereof can adsorb the movable portion 100 toward the protection elements 710 and 720 , so that the guiding elements 510 and 520 are supported by the corresponding portions 530 and 540 disposed on the supporting portions 450 and 470 .

[0089] Therefore, the protection elements 710 and 720 can prevent magnetic field interference when the movable part 100 moves, and can also make the movement of the movable part 100 more stable through the contact between the guiding elements 510 and 520 and the corresponding parts 530 and 540 .
