[0039] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0040] Embodiments of the present application relate to an optical element driving mechanism 100, which can be used to implement functions such as taking pictures and recording videos in terminal products such as mobile phones and tablet computers. As Figure 1 and Figure 2As shown in the figure, the optical element driving mechanism 100 includes a carrier 2, a first frame 3, a pair of oppositely arranged first elastic members 41, a second frame 5, a pair of oppositely arranged second elastic members 42, a circuit board 7, and a base 8. The circuit board 7 is disposed on the base 8 and is configured with a first set of coils and a second set of coils. The carrier 2 is movably disposed within the first frame 3 and is provided with a third set of coils 21. The first frame 3 is movably disposed within the second frame 5, and the first frame 3 is provided with a first set of magnets 61 that cooperate with the first set of coils and the third set of coils 21. The second frame 5 is movably disposed on the base 8, and the second frame 5 is provided with a second set of magnets 62 that cooperate with the second set of coils. Among them, when the first set of coils is energized, it cooperates with the first set of magnets 61 to drive the first frame 3 to move in the first direction to achieve the optical image stabilization function. When the second set of coils is energized, it cooperates with the second set of magnets 62 to drive the second frame 5 to move in the second direction to achieve the optical image stabilization function. When the third set of coils 21 is energized, it cooperates with the first set of magnets 61 to drive the carrier 2 to move in the optical axis direction to achieve the zoom function, and the first direction, the second direction, and the optical axis direction are perpendicular to each other in pairs. The first direction can be the X direction as shown in the figure, the second direction can be the Y direction as shown in the figure, and the optical axis direction is the Z-axis direction. In the following text, the movement in the first direction will be described as the movement in the X-axis direction, and the movement in the second direction will be the movement in the Y-axis direction.

[0041] Specifically, as Figure 1 and Figure 2 shown, the base 8 is provided with circuit pins 81 and is electrically connected to the circuit board 7 disposed on the base 8 through the circuit pins 81. The first set of coils (not shown in the figure) and the second set of coils (not shown in the figure) are built into the circuit board 7, and the circuit board 7 can supply power to the first set of coils, the second set of coils, and the third set of coils 21.

[0042] As Figure 1 and Figure 2 shown, a pair of first elastic members 41 are respectively located outside the two first side walls 51 of the second frame 5 oppositely arranged in the first direction, and each first elastic member 41 is connected to the first frame 3 and the second frame 5. A pair of second elastic members 42 are respectively located outside the two second side walls 52 of the second frame 5 oppositely arranged in the second direction, and each second elastic member 42 is connected to the second frame 5 and the base 8. The optical element driving mechanism 100 preferably includes a housing 1, and the housing 1 is sleeved outside the second frame 5. This makes the installation between components convenient, and the installation structure of the driving mechanism is more reasonable and compact.

[0043] As can be seen from the above, through the cooperation of the first set of coils and the first set of magnets 61, the first frame 3 is moved in the first direction. Through the cooperation of the second set of coils and the second set of magnets 62, the second frame 5 is moved in the second direction. Through the cooperation of the third set of coils 21 and the first set of magnets 61, the carrier 2 is moved in the optical axis direction. Thus, the optical element is adjusted and moved in the first direction, the second direction, and the optical axis direction. And through the first elastic member 41, the first frame 3 can be driven to buffer and reset in the first direction. Through the second elastic member 42, the second frame 5 can be driven to buffer and reset in the second direction. Furthermore, the carrier 2 carrying the optical element moves smoothly, achieving an anti-shake function. In addition, the first elastic member 41 and the second elastic member 42 are arranged outside the second frame 5, which can make the assembly of the optical element driving mechanism 100 more convenient, and the overall structure is more reasonable and compact.

[0044] It should be noted that the first set of magnets 61 may include only one magnet, and the second set of magnets 62 may also include only one magnet. Here, the first group and the second group do not limit the number of paired magnets.

[0045] The implementation details of this embodiment will be specifically described below. The following content is only the implementation details provided for convenient understanding and is not necessary for implementing this solution.

[0046] Further, as Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, the four corners of the second frame 5 are provided with avoidance holes 50, and the four corners of the first frame 3 are provided with extension parts 31. Each extension part 31 penetrates through the corresponding avoidance hole 50 and is connected to the first elastic member 41. That is, the four extension parts 31 respectively extend out from the four avoidance holes 50. One first elastic member 41 is connected to two of the extension parts 31, and the other first elastic member 41 is connected to the other two extension parts 31, realizing the connection between the first elastic member 41 and the first frame 3. There is a gap between the first frame 3 and the inner side wall of the second frame 5 in the X-axis direction. After the first set of coils is energized and cooperates with the first set of magnets 61, the first frame 3 can move relative to the second frame 5. When the first frame 3 moves in the X-axis direction, the first elastic member 41 can limit the movement range of the first frame 3 with the positioning of the second frame 5 and can buffer the movement of the first frame 3.

[0047] Further, as Figure 2 、 Figure 3 、 Figure 4 and Figure 5 ​As shown, a first protrusion 53 connected to the first elastic member 41 is provided on the outer side of the first side wall 51. When the first frame 3 and the second frame 5 are in the starting position, the first fixing surface 530 of the first protrusion 53 and the extended fixing surface 310 of the extension 31 on the same side as the first protrusion 53 are in the same vertical plane.

[0048] Further, as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, there are a pair of first protrusions 53 on one first side wall 51, and they are arranged oppositely along the length direction of the first side wall 51. The first elastic member 41 has a first elastic body 411, a pair of first upper contact ends 412, and a pair of first lower contact ends 413; the pair of first upper contact ends 412 are respectively arranged at both ends of the first elastic body 411 in the length direction. The pair of first lower contact ends 413 are respectively arranged at both ends of the first elastic body 411 in the length direction. Among them, the pair of first upper contact ends 412 are respectively connected to the pair of first protrusions 53 on their respective sides, and the pair of first lower contact ends 413 are respectively connected to the pair of extensions 31 protruding on their respective sides. Thus, after the first frame 3 and the second frame 5 are installed, the first elastic member 41 can be installed on the outer side of the second frame 5, and the first elastic member 41 can also be connected to the first frame 3 and the second frame 5, realizing the installation of the first elastic member 41, and the installation is more convenient, and the installation structure is more reasonable and compact.

[0049] In addition, as Figure 2 and Figure 5 shown, second protrusions 80 are provided at the four corners of the base 8. The second elastic member 42 has a second elastic body 421, a pair of second upper contact ends 422, and a pair of second lower contact ends 423. The pair of second upper contact ends 422 are respectively arranged at both ends of the second elastic body 421 in the length direction, and the pair of second lower contact ends 423 are respectively arranged at both ends of the second elastic body 421 in the length direction. Among them, the pair of second upper contact ends 422 are connected to the outer side of the second side wall 52; the pair of second lower contact ends 423 are respectively connected to the second protrusions 80 on their respective sides. There is no play between the first frame 3 and the second frame 5 in the Y-axis direction. When the second frame 5 is driven to move in the Y-axis direction by cooperating with the second group of magnets 62 when the second group of coils is energized, the second frame 5 drives the first frame 3 to move in the Y-axis direction, and the first frame 3 is also connected to the carrier 2 for placing the optical element, so that the optical element can move in the Y-axis direction. When the second frame 5 moves in the Y-axis direction, the second elastic member 42 can limit the movement range of the second frame 5 with the positioning of the base 8, and can buffer the movement of the second frame 5 to prevent the lens from shaking. The reasonable installation of the second elastic piece is realized, and the installation is convenient.

[0050] Further, as Figure 3and Figure 5 As shown, among the first group of magnets 61, there are some magnets that cooperate with the third group of coils 21 and some that cooperate with the first group of coils. There may be 4 magnets in the first group of magnets 61. Two of the magnets are located above the other two. The two magnets located above cooperate with the third group of coils 21 to drive the carrier 2 to move along the optical axis direction, and the two magnets located below cooperate with the first group of coils to drive the first frame 3 to move along the X-axis direction. It can be understood that in other embodiments, the number of magnets in the first group of magnets 61 can also be two. The two magnets cooperate with both the third group of coils 21 and the first group of coils, that is, the first group of coils and the third group of coils 21 share the magnets. The number of magnets in the first group of magnets 61 is not limited to the above numbers and can also be 1 or more, for the first group of coils and the third group of coils 21 to share, or be multiple for the first group of coils and the third group of coils 21 to use separately.

[0051] In addition, as Figure 2 、 Figure 3 and Figure 5 shown, a pair of first grooves 32 are provided on the first frame 3 and are oppositely arranged along the second direction. The magnets in the first group of magnets 61 are respectively used to be placed in the pair of first grooves 32. Among the 4 magnets in the first group of magnets 61 in the figure, 2 magnets are arranged in one first groove 32, and the other two magnets are arranged in the other first groove 32, so that the first frame 3 and the carrier 2 are evenly stressed and the first frame 3 and the carrier 2 are more stably limited.

[0052] Furthermore, as Figure 2 、 Figure 4 and Figure 5 shown, a pair of second grooves 54 are provided on the second frame 5 and are oppositely arranged along the first direction. The magnets of the second group of magnets 62 are respectively used to be placed in the second grooves 54. The two magnets in the second group of magnets 62 are oppositely arranged, one magnet is in one first groove 32, and the other magnet is in the other groove. Thus, the second frame 5 and the carrier 2 are evenly stressed and the second frame 5 is more stably limited.

[0053] More notably, as Figure 3 、 Figure 4 and Figure 5 shown, at the bottom ends of a pair of side walls of the first frame 3 that are oppositely arranged along the first direction, avoidance grooves 33 are provided. The second frame 5 has a pair of embedding parts 55 that are respectively embedded in the pair of avoidance grooves 33, and a pair of second grooves 54 are respectively provided in the pair of embedding parts 55. The embedding parts 55 can further limit and support the first frame 3, so that the cooperation between the first frame 3 and the second frame 5 is more stable.

[0054] Furthermore, as Figure 1 、 Figure 2As shown, the optical element driving mechanism 100 further includes an upper reed 91 and a lower reed 92. The upper reed 91 is connected to the upper surface of the first frame 3 and the upper surface of the carrier 2, and the lower reed 92 is connected to the lower surface of the first frame 3 and the lower surface of the carrier 2. Both the upper reed 91 and the lower reed 92 include a first portion fixed to the carrier 2 and a second portion extending outwardly and bent from the first portion. The first portion of the upper reed 91 is attached to the upper surface of the carrier 2, and the second portion of the upper reed 91 is connected to the upper surface of the first frame 3. The first portion of the lower reed 92 is attached to the lower surface of the carrier 2, and the second portion of the lower reed 92 is connected to the lower surface of the first frame 3. When the carrier 2 moves in the optical axis direction after the third set of coils 21 is energized, the upper reed 91 and the lower reed 92 can limit the movement range of the carrier 2 with the positioning of the first frame 3 and can buffer the movement of the carrier 2.

However, it should be understood that if necessary, aspects of the embodiments can be modified to adopt aspects, features, and concepts of various patents, applications, and publications to provide additional embodiments.
