[0002] With the development of technology, many electronic devices today (such as smartphones or digital cameras) have the function of taking pictures or recording videos. The use of these electronic devices is becoming more and more common, and they are developing towards convenient and thinner designs to provide users with more choices.

[0075] This utility model relates to an optical element driving mechanism 100, which includes a base 1, a frame 2, a support 31, a bracket 3 connected to the support 31, a carrier 4, a spring 5, and a shell 6.

[0076] The base 1 includes a base plate 11, built-in wiring 15, support columns 12, adsorption metal sheets, and a circuit board. The base plate 11 is rectangular and connected to the outer shell 6 to form a receiving space to accommodate the frame 2, carrier 4, support base 31, support 3, spring 5, and circuit board. The base plate 11 and the outer shell 6 are respectively provided with light-blocking holes aligned with each other to prevent light from entering the receiving space.

[0077] The four support columns 12 are respectively connected to the four feet of the base plate 11.

[0078] The built-in wiring 15 is located within the base plate 11, and four of the connection ends of the built-in wiring 15 extend to the top surface of the support column 12.

[0079] Multiple adsorption metal sheets are distributed on the adjacent sides of the base plate 11. The adsorption metal sheet is the first adsorption metal sheet 16. The adsorption metal sheet can adsorb the OIS magnet group 21 on the frame 2, which will be described in detail below.

[0080] The circuit board is stacked on the top surface of the base plate 11 and has an OIS coil group 132 inside. The circuit board and the built-in circuit 15 are electrically connected. This circuit board is defined as the first circuit board 13.

[0081] The first circuit board 13 also includes a sensing capacitor 17 and a driving capacitor 18, wherein the driving capacitor 18 and the sensing capacitor 17 are located in a groove in the base plate 11 and do not protrude from the top surface of the first circuit board 13. The driving capacitor 18 is electrically connected to the OIS coil group 132 and is used to control the OIS coil group 132.

[0082] The frame 2, the bracket and the bracket base are combined to form a frame assembly, which is located on the top surface of the base plate 11 and is rotatably connected to the base plate 11.

[0083] Specifically, the frame 2 is a rectangular frame and includes four side plates. The bottom surface of the frame 2 is provided with two magnetic grooves 22 and two movable grooves 221. The two magnetic grooves 22 are located on the bottom surface of adjacent side plates of the frame 2. The two magnetic grooves 22 are respectively used to install OIS magnet groups 21. The OIS magnet groups 21 and the OIS coil group 132 of the base 1 cooperate to drive the frame 2 to roll along the first direction and the second direction.

[0084] The two movable grooves 221 are formed by the top walls of the two magnet grooves 22 being recessed towards the top.

[0085] The frame 2 has mounting slots 24 at its three corners. These three mounting slots 24 and two magnet slots 22 are arranged alternately. That is, one of the mounting slots 24 is located at the included angle between the side plates where the two magnet slots 22 are located. The three mounting slots 24 are respectively connected to the movable grooves 221 of the two magnet slots 22.

[0086] The top walls of the three mounting slots 24 are respectively provided with a first X-axis rolling groove 241. The first X-axis rolling groove 241 extends along the second direction and is used to install a rolling element whose axis extends along the second direction. The rolling element is defined as an X-axis rolling element 7, which can be a ball or a roller.

[0087] Three support seats 31 are located in three mounting slots 24 respectively, and the top wall of each support seat 31 is provided with a second X-axis rolling groove 32. Each second X-axis rolling groove 32 and each corresponding first X-axis rolling groove 241 cooperate to form a space to accommodate each X-axis rolling element 7, thereby allowing the three support seats 31 and the frame 2 to move relative to each other in the first direction.

[0088] The bottom walls of the three support seats 31 are provided with recessed first Y-axis rolling grooves 33. The four corners of the base plate 11 are respectively provided with protruding bosses 14. The top surface of each boss 14 is basically flush with the top surface of the first circuit board 13. The three bosses 14 are respectively provided with second Y-axis rolling grooves 141. The three second Y-axis rolling grooves 141 are respectively aligned with the three first Y-axis rolling grooves 33. Each second Y-axis rolling groove 141 and each first Y-axis rolling groove 33 are arranged opposite to each other and form a space to accommodate the rolling element. The rolling element is defined as a Y-axis rolling element 8, which is also a roller. The axis of the Y-axis rolling element 8 is perpendicular to the axis of the first rolling element. The axis of the Y-axis rolling element 8 extends along the first direction. The three support seats 31 can drive the frame 2 to roll along the second direction.

[0089] The three support seats 31 are connected by two supports 3, which allows the three support seats 31 to roll synchronously. The support 3 includes an integrally formed metal sheet 34 and two connecting pieces 35. The metal sheet 34 is elongated and located in the movable groove 221. The top ends of the two connecting pieces 35 are integrally formed with the two ends of the metal sheet 34, and the bottom ends extend into two adjacent mounting grooves 24 and are connected to the two support seats 31 in the mounting grooves 24.

[0090] The entire support 3 is U-shaped, and the OIS magnet group 21 is located inside the support 3, which can prevent the support 3 from detaching from the frame 2.

[0091] The two supports 3 are made of metal, while the support base 31 is made of plastic. The supports 3 and the support base 31 are integrally injection molded.

[0092] After the bracket 31 is installed in the mounting slot 24 of the frame 2, its bottom surface is basically flush with the bottom surface of the frame 2. The bracket 31 is connected to the base plate 11 by rolling via the Y-axis rolling element 8. The bottom surface of the frame 2 and the bottom surface of the bracket 31 will not directly contact the base plate 11, and the bracket 31 will not protrude from the bottom surface of the frame 2. The distance between the bracket 31 and the frame 2 and the base plate 11 can be very small, as long as they do not contact each other. The bracket 31 does not occupy too much space in the optical axis direction, which can reduce the size of the entire optical element driving mechanism 100 along the optical axis direction, making the optical element driving mechanism 100 lighter and thinner.

[0093] The X-axis rolling element 7 and the Y-axis rolling element 8 can be designed as either cylindrical or semi-cylindrical structures, and can also serve as guides and supports.

[0094] In addition, the multiple first adsorption metal sheets 16 of the base plate 11 are located below the OIS magnet group 21 to adsorb the OIS magnet group 21, thereby generating an adsorption force between the base plate 11 and the OIS magnet of the frame 2, which improves the compactness of the connection between the base 1 and the support 31 and the frame 2.

[0095] The bottom surface of the frame 2 is also provided with a ball groove, which is defined as the top ball groove 25. The top ball groove 25 and the three mounting grooves 24 are located at the four corners of the frame 2 respectively.

[0096] The top surface of another boss 14 on the base plate 11 is also provided with a corresponding bottom ball groove 142. The bottom ball groove 142 and the top ball groove 2 are aligned along the optical axis to form a space for accommodating the ball 9. The ball 9 can make the frame 2 operate more stably.

[0097] The carrier 4 is located inside the ring of the frame 2, and the carrier 4 can move along the optical axis direction, which is... Figure 1 and Figure 2 The vertical direction, the optical axis direction, the first direction and the second direction are perpendicular to each other.

[0098] In one embodiment, the frame 2 is provided with a clearance opening 26, which is located on one of the side plates of the frame 2 and contains an AF coil assembly 271. The carrier 4 is provided with an AF magnet assembly 42, which cooperates with the AF coil assembly 271 to drive the carrier 4 to move along the optical axis.

[0099] In addition, the inner side of the side plate is provided with two first Z-axis rolling grooves 29, and the clearance opening 26 is located between the two first Z-axis rolling grooves 29.

[0100] The carrier 4 is also provided with two second Z-axis rolling grooves 41 on its radial outer side. The two second Z-axis rolling grooves 41 are respectively arranged opposite to the two first Z-axis rolling grooves 29 to form a space for installing two rolling elements. The two rolling elements are Z-axis rolling elements 43. The Z-axis rolling elements 43 are rollers whose axis extends along the optical axis. When the carrier 4 moves along the optical axis, it is connected to the frame 2 by rolling through the Z-axis rolling elements 43, and will not directly touch the frame 2, thus reducing friction.

[0101] To prevent the Z-axis rolling element 43 from detaching from the frame 2 along the optical axis, the first Z-axis rolling groove 29 has a bottom wall that can support the Z-axis rolling element 43.

[0102] The top opening of the first Z-axis rolling groove 29 is also covered with a pressure plate 236, which is used to restrict the Z-axis rolling element 43 from disengaging from the frame 2 along the optical axis.

[0103] The frame 2 is also provided with a second circuit board 27 and a second adsorption metal sheet 28. The second circuit board 27 is attached to the outside of the frame 2 and covers the clearance opening 26, while the second adsorption metal sheet 28 is installed on the outer side of the second circuit board 27 and aligned with the AF magnet group 42 for adsorbing the AF magnet group 42, so that the carrier 4 can abut against the Z-axis rolling element 43.

[0104] The second circuit board 27 is also electrically connected to the AF coil group 271.

[0105] The frame 2 is also provided with a first built-in metal frame 23 and a second built-in metal frame 44, which includes three parts that are insulated from each other. The first part 231 is located in a side plate with a clearance opening 26 and is electrically connected to the second circuit board 27. It is also welded to the pressure plate 236 to fix the pressure plate 236 to the frame 2.

[0106] The second part 232 is embedded in the two side plates of the magnet groove 22 and is L-shaped. The second part 232 is attached to the top and side surfaces of the OIS magnet assembly 21 and avoids the movable groove 221 for adsorbing the OIS magnet assembly 21.

[0107] The third part 233 is located inside the last side plate of the frame 2 and is used for electrical connection with the first sensing sheet 234 and the second electrode sheet 235 described below. Specifically, the third part 233 is integrally formed with the first sensing sheet 234 and the second electrode sheet 235.

[0108] Specifically, the frame 2 is provided with a first sensing sheet 234 and a second electrode sheet 235, while the carrier 4 is provided with a first electrode sheet 45. The first electrode sheet 45 and the first sensing sheet 234 are arranged opposite to each other to form a first capacitor, which is electrically connected to the sensing capacitor 17 of the base 1.

[0109] The first electrode plate 45 can move along the optical axis with the carrier 4, and the capacitance of the first capacitor also changes accordingly. The sensing capacitor 17 can determine the displacement of the carrier 4 by the change in the capacitance of the first capacitor.

[0110] The base plate 11 contains a second sensing plate 131. The second sensing plate 131 and the second electrode plate 235 of the frame 2 are arranged opposite each other to form a second capacitor. The second capacitor is also electrically connected to another sensing capacitor 17 of the base 1 to sense the displacement of the frame 2 along the first direction. Of course, the frame 2 can also be provided with other electrode plates, and the base plate 11 can be provided with other sensing plates. These sensing plates and the electrode plates form another capacitor to sense the displacement of the frame 2 along the second direction. The principle is the same and will not be described again.

[0111] The carrier 4 has a second built-in metal frame 44, which is also divided into two parts. One part is integrally formed with the first electrode sheet 45 on the outside of the carrier 4. The other part is attached to the inside of the AF magnet assembly 42 to improve the stability of the AF magnet assembly 42 installation structure.

[0112] The reed 5 is elastic and located on the top surface of the frame 2 and the carrier 4. The reed 5 is elastically connected to the frame 2 and the carrier 4 and is used to drive the carrier 4 to reset.

[0113] In addition, the spring 5 is electrically connected to the built-in circuit 15 of the base 1, specifically to several connecting ends at the top of the support column 12. The first built-in metal frame 23 in the frame 2 and the second built-in metal frame 44 of the carrier 4 are respectively electrically connected to the upper spring 5. The built-in circuit 15 is electrically connected to an external power source, which can energize the first built-in metal frame 23 and the second built-in metal frame 44.

[0114] The top and bottom surfaces of the carrier 4 are respectively provided with anti-collision gel 46, which is used to buffer the collision force when the carrier 4 moves in the optical axis direction.

[0115] The preferred embodiments of the present invention have been described in detail above, but it should be understood that, if necessary, aspects of the embodiments can be modified to utilize aspects, features, and concepts from various patents, applications, and publications to provide other embodiments.

[0116] In light of the detailed description above, these and other changes can be made to the embodiments. Generally, the terminology used in the claims should not be considered limited to the specific embodiments disclosed in the specification and claims, but should be understood to include all possible embodiments together with the full scope of equivalents enjoyed by these claims.

[0117] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
