As Figure 1 shown, an optical element driving mechanism 100 according to some embodiments of the present disclosure can be installed in an electronic device 1 for taking pictures or videos, where the aforementioned electronic device 1 can be, for example, a smart phone or a digital camera, but the present disclosure is not limited thereto. It should be noted thatFigure 1 The positional and size relationship between the optical element driving mechanism 100 and the electronic device 1 shown in the figure is only an example, rather than limiting the positional and size relationship between the optical element driving mechanism 100 and the electronic device 1. In fact, the optical element driving mechanism 100 can be installed at different positions in this electronic device 1 according to different requirements.

[0107] Please refer to Figure 2 and Figure 3 . Figure 2 FIG. is a schematic diagram of an optical element driving mechanism 100, a first optical element OE1, and a second optical element OE2 according to some embodiments of the present disclosure, where the outer frame 111 is shown by a dashed line. Figure 3 FIG. is an exploded view of an optical element driving mechanism 100, a first optical element OE1, and a second optical element OE2 according to some embodiments of the present disclosure.

[0108] The optical element driving mechanism 100 may include a fixing portion 110, a first moving portion 120, a second moving portion 130, a first driving assembly 140, a second driving assembly 150, a first stopping assembly 160, a second stopping assembly 170, a circuit assembly 180, and a connecting element 190.

[0111] As Figure 2 shown, a light ray L may enter the second optical element OE2 from the outside of the optical element driving mechanism 100 along a first direction D1. The second optical element OE2 refracts and / or reflects the light ray L from the first direction D1 to enter the first optical element OE1 along the optical axis OA (which may also be a third direction D3 perpendicular to the first direction D1).

The first driving magnet 141 can be disposed on the first movable part 120, and the first driving coil 142 can be disposed on the base 112 such that when the first driving coil 142 receives current from the circuit assembly 180, the first driving magnet 141 will drive the first movable part 120 to move along the optical axis OA relative to the fixed part 110.

[0115] The second driving assembly 150 can drive the second movable part 130 to move relative to the fixed part 110.

The second driving magnets 151 can be disposed on the second movable part 130, and the second driving coils 152 can be disposed on the base 112 such that when the second driving coils 152 receive current from the circuit assembly 180, the second driving magnets 151 will drive the second movable part 130 to move relative to the fixed part 110 about a direction perpendicular to the optical axis OA. For example, the second driving magnets 151 drive the second movable part 130 to rotate relative to the fixed part 110 about the first direction D1 and / or the second direction D2.

[0116] The first stopping assembly 160 can limit the movement range of the first movable part 120. The first stopping assembly 160 can include a first contact element 161, a first shock absorbing element 162, and a first fixing element 163.

[0117] The second stopping assembly 170 can limit the movement range of the first movable part 120. The second stopping assembly 170 can also limit the movement range of the second movable part 130. The second stopping assembly 170 can include a second contact element 171, a second shock absorbing element 172, and a second fixing element 173.

[0118] The circuit assembly 180 can be connected to an external circuit and electrically connected to the first driving assembly 140 and the second driving assembly 150. According to some embodiments of the present disclosure, the circuit assembly 180 can be electrically connected to the first driving coil 142 of the first driving assembly 140 and the second driving coils 152 of the second driving assembly 150.

The first fixing element 163 can fix the first shock-absorbing element 162, so that the first shock-absorbing element 162 is fixed to the base 112. When the first movable part 120 is located at a first limit position, the first shock-absorbing element 162 contacts the first contact element 161 to limit the movement range of the first movable part 120.

[0121] According to some embodiments of the present disclosure, the Young's modulus of the first contact element 161 is different from that of the first shock-absorbing element 162.

The fourth surface 1622d of the first shock-absorbing element is substantially parallel to the second surface 1622b of the first shock-absorbing element; however, the fourth surface 1622d of the first shock-absorbing element faces the opposite direction to the second surface 1622b of the first shock-absorbing element. Specifically, the fourth surface 1622d of the first shock-absorbing element is perpendicular to the second direction D2.

[0129] The first fixing surface 1623a and the second fixing surface 1623b of the first shock-absorbing element are located on the body 1621 of the first shock-absorbing element. The first fixing surface 1623a of the first shock-absorbing element faces the first fixing element 163, and the second fixing surface 1623b of the first shock-absorbing element faces the first fixing surface 1623a of the first shock-absorbing element. The first fixing surface 1623a and the second fixing surface 1623b of the first shock-absorbing element extend from the third surface 1622c of the first shock-absorbing element in a direction perpendicular to the third surface 1622c of the first shock-absorbing element, so that there is a receiving space between the first fixing surface 1623a and the second fixing surface 1623b of the first shock-absorbing element. The first fixing surface 1623a of the first shock-absorbing element extends farther from the third surface 1622c of the first shock-absorbing element than the second fixing surface 1623b of the first shock-absorbing element (that is, the first fixing surface 1623a of the first shock-absorbing element is "higher" than the second fixing surface 1623b of the first shock-absorbing element).

[0130] A connecting element 190 is arranged in the receiving space between the first fixing surface 1623a and the second fixing surface 1623b of the first shock-absorbing element, so that the connecting element 190 can stay in the receiving space between the first fixing surface 1623a and the second fixing surface 1623b of the first shock-absorbing element. And, the connecting element 190 will not overflow from the first fixing surface 1623a of the first shock-absorbing element, thereby making the optical element driving mechanism 100 more stable.

[0131] The uneven structure 1624 of the first shock-absorbing element is formed on the first surface 1622a of the first shock-absorbing element, and when the first moving part 120 is located at the first extreme position, the uneven structure 1624 of the first shock-absorbing element contacts the first contact element 161.

[0132] The first opening 1625a of the first shock-absorbing element is formed on the second surface 1622b of the first shock-absorbing element, and the second opening 1625b of the first shock-absorbing element is formed on the fourth surface 1622d of the first shock-absorbing element, so that when viewed from the first direction D1, the first shock-absorbing element 162 can have a substantially I shape (please refer to Figure 4 ).

[0133] In this way, the Young's modulus of the first shock-absorbing element 162 can be reduced, thereby effectively restricting the movement range of the first moving part 120 and slowing down the impact caused by the first moving part 120.

[0134] The first hollow portion 1626a of the first shock-absorbing element is formed on the first surface 1622a of the first shock-absorbing element body 1621, and the first hollow portion 1626a of the first shock-absorbing element has an elongated structure. The first hollow portion 1626a of the first shock-absorbing element penetrates through the first shock-absorbing element body 1621, and the first hollow portion 1626a of the first shock-absorbing element is parallel to the optical axis OA.

[0135] The second hollow portion 1626b of the first shock-absorbing element is formed on the second surface 1622b of the first shock-absorbing element body 1621, and the second hollow portion 1626b of the first shock-absorbing element has an elongated structure. The second hollow portion 1626b of the first shock-absorbing element penetrates through the first shock-absorbing element body 1621, and the second hollow portion 1626b of the first shock-absorbing element is perpendicular to the first hollow portion 1626a of the first shock-absorbing element. Specifically, the second hollow portion 1626b of the first shock-absorbing element is parallel to the second direction D2.

[0136] The third hollow portion 1626c of the first shock-absorbing element is formed on the third surface 1622c of the first shock-absorbing element body 1621, and the third hollow portion 1626c of the first shock-absorbing element has an elongated structure. The third hollow portion 1626c of the first shock-absorbing element penetrates through the first shock-absorbing element body 1621, and the third hollow portion 1626c of the first shock-absorbing element is perpendicular to the first hollow portion 1626a and the second hollow portion 1626b of the first shock-absorbing element. Specifically, the third hollow portion 1626c of the first shock-absorbing element is parallel to the first direction D1.

[0137] In this way, the Young's modulus of the first shock-absorbing element 162 can be reduced, thereby effectively restricting the movement range of the first moving portion 120 and slowing down the impact caused by the first moving portion 120.

[0138] Please refer to Figure 4 、 Figure 5 at the same time. The second contact element 171 is located on the first moving portion 120, and the second fixing element 173 is located on the base 112. The second fixing element 173 can fix the second shock-absorbing element 172 so that the second shock-absorbing element 172 is fixed to the base 112. When the first moving portion 120 is located at a second limit position, the second shock-absorbing element 172 contacts the second contact element 171 to restrict the movement range of the first moving portion 120.

[0139] According to some embodiments of the present disclosure, the Young's modulus of the second contact element 171 is different from that of the second shock-absorbing element 172. According to some embodiments of the present disclosure, the Young's modulus of the second fixing element 173 is different from that of the second shock-absorbing element 172. According to some embodiments of the present disclosure, the Young's modulus of the second contact element 171 is greater than that of the second shock-absorbing element 172. According to some embodiments of the present disclosure, the Young's modulus of the second fixing element 173 is greater than that of the second shock-absorbing element 172. According to some embodiments of the present disclosure, the Young's modulus of the second fixing element 173 is the same as that of the second contact element 171.

[0140] The second shock-absorbing element 172 is at least partially located in a second groove 1731 of the second fixing element 173. The second shock-absorbing element 172 is connected to the second fixing element 173 via a connecting element 190.

[0141] The second fixing element 173 includes a first groove 1732 and a second groove 1733. The first groove 1732 is recessed away from the second shock-absorbing element along the second direction D2, and the second groove 1733 is also recessed away from the second shock-absorbing element along the second direction D2. However, the recessing direction of the first groove 1732 is opposite to that of the second groove 1733. The first groove 1732 and the second groove 1733 are provided with the connecting element 190, and the connecting element 190 contacts the second shock-absorbing element 172 to fix the second shock-absorbing element 172 to the second fixing element 173.

[0142] Please refer to Figure 7 , Figure 7 which is a perspective view of the second shock-absorbing element 172 according to some embodiments of the present disclosure.

[0143] The second shock-absorbing element 172 may include a second shock-absorbing element body 1721, a first surface 1722a of the second shock-absorbing element, a second surface 1722b of the second shock-absorbing element, a third surface 1722c of the second shock-absorbing element, a fourth surface 1722d of the second shock-absorbing element, a first fixing surface 1723a of the second shock-absorbing element, a second fixing surface 1723b of the second shock-absorbing element, a concavo-convex structure 1724 of the second shock-absorbing element, a first hollow portion 1725a of the second shock-absorbing element, a second hollow portion 1725b of the second shock-absorbing element, a third hollow portion 1725c of the second shock-absorbing element, and a fourth hollow portion 1725d of the second shock-absorbing element.

[0144] The first surface 1722a of the second shock-absorbing element is located on the second shock-absorbing element body 1721, and the first surface 1722a of the second shock-absorbing element faces the second contact element 171. Specifically, the first surface 1722a of the second shock-absorbing element is substantially perpendicular to the optical axis OA.

[0145] The second surface 1722b of the second shock-absorbing element is located on the second shock-absorbing element body 1721, and the second surface 1722b of the second shock-absorbing element faces away from the second contact element 171. The second surface 1722b of the second shock-absorbing element is substantially parallel to the first surface 1722a of the second shock-absorbing element; however, the second surface 1722b of the second shock-absorbing element faces the opposite direction to the first surface 1722a of the second shock-absorbing element. Specifically, the second surface 1722b of the second shock-absorbing element is substantially perpendicular to the optical axis OA.

[0146] The first surface 1722a of the second shock-absorbing element extends away from the second shock-absorbing element body 1721 along the second direction D2, and the second surface 1722b of the second shock-absorbing element also extends away from the second shock-absorbing element body 1721 along the second direction D2. However, the extending direction of the first surface 1722a of the second shock-absorbing element is opposite to the extending direction of the second surface 1722b of the second shock-absorbing element. So that when viewed from the first direction D1, the second shock-absorbing element 172 can have a substantially Z shape (refer to Figure 4 ).

[0147] In this way, the Young's modulus of the second shock-absorbing element 172 can be reduced, and further, the movement range of the first movable part 120 can be effectively restricted, and the impact caused by the first movable part 120 can be slowed down.

[0148] The third surface 1722c of the second shock-absorbing element is located on the second shock-absorbing element body 1721, and the third surface 1722c of the second shock-absorbing element is adjacent to the first surface 1722a of the second shock-absorbing element. The third surface 1722c of the second shock-absorbing element and the first surface 1722a of the second shock-absorbing element are not parallel. Specifically, the third surface 1722c of the second shock-absorbing element is perpendicular to the first direction D1.

[0149] The fourth surface 1722d of the second shock-absorbing element is located on the second shock-absorbing element body 1721, and the fourth surface 1722d of the second shock-absorbing element is adjacent to the first surface 1722a of the second shock-absorbing element and the third surface 1722c of the second shock-absorbing element. The fourth surface 1722d of the second shock-absorbing element is not parallel to the first surface 1722a of the second shock-absorbing element and the third surface 1722c of the second shock-absorbing element. Specifically, the fourth surface 1722d of the second shock-absorbing element is perpendicular to the second direction D2.

[0150] The first fixing surface 1723a of the second shock-absorbing element and the second fixing surface 1723b of the second shock-absorbing element are located on the second shock-absorbing element body 1721. The first fixing surface 1723a of the second shock-absorbing element faces the second fixing element 173, and the second fixing surface 1723b of the second shock-absorbing element faces the first fixing surface 1723a of the second shock-absorbing element. The first fixing surface 1723a of the second shock-absorbing element and the second fixing surface 1723b of the second shock-absorbing element extend along the first direction D1 from the third surface 1722c of the second shock-absorbing element, so that there is an accommodation space between the first fixing surface 1723a of the second shock-absorbing element and the second fixing surface 1723b of the second shock-absorbing element.

[0151] A connecting element 190 is arranged in the accommodation space between the first fixing surface 1723a of the second shock-absorbing element and the second fixing surface 1723b of the second shock-absorbing element, so that the connecting element 190 can stay in the accommodation space between the first fixing surface 1723a of the second shock-absorbing element and the second fixing surface 1723b of the second shock-absorbing element. Moreover, the connecting element 190 will not overflow from the first fixing surface 1723a of the second shock-absorbing element, thereby making the optical element driving mechanism 100 more stable.

[0152] The concavo-convex structure 1724 of the second shock-absorbing element is formed on the first surface 1722a of the second shock-absorbing element, and when the first movable part 120 is located at the second extreme position, the concavo-convex structure 1724 of the second shock-absorbing element contacts the second contact element 171.

[0153] In this way, the Young's modulus of the second shock-absorbing element 172 can be reduced, thereby effectively restricting the movement range of the first movable part 120 and slowing down the impact caused by the first movable part 120.

[0154] The first hollow part 1725a of the second shock-absorbing element is formed on the first surface 1722a of the second shock-absorbing element body 1721, and the first hollow part 1725a of the second shock-absorbing element has an elongated structure. The first hollow part 1725a of the second shock-absorbing element penetrates through the second shock-absorbing element body 1721, and the first hollow part 1725a of the second shock-absorbing element is parallel to the optical axis OA.

[0155] The second hollow part 1725b of the second shock-absorbing element is formed on the second surface 1722b of the second shock-absorbing element body 1721, and the second hollow part 1725b of the second shock-absorbing element has an elongated structure. The second hollow part 1725b of the second shock-absorbing element penetrates through the second shock-absorbing element body 1721 and reaches the first surface 1722a of the second shock-absorbing element, and the second hollow part 1725b of the second shock-absorbing element is parallel to the first hollow part 1725a of the second shock-absorbing element. Specifically, the second hollow part 1725b of the second shock-absorbing element is parallel to the optical axis OA.

[0156] The third hollow portion 1725c of the second shock-absorbing element has an elongated structure. The third hollow portion 1725 penetrates through the body 1721 of the second shock-absorbing element, and the third hollow portion 1725c of the second shock-absorbing element is perpendicular to the first hollow portion 1725a and the second hollow portion 1725b of the second shock-absorbing element. Specifically, the third hollow portion 1725c of the second shock-absorbing element is parallel to the first direction D1.

[0157] The fourth hollow portion 1725d of the second shock-absorbing element is formed on the fourth surface 1722d of the body 1721 of the second shock-absorbing element, and the fourth hollow portion 1725d of the second shock-absorbing element has an elongated structure. The fourth hollow portion 1725d of the second shock-absorbing element penetrates through the body 1721 of the second shock-absorbing element, and the second hollow portion 1626b of the first shock-absorbing element is perpendicular to the first hollow portion 1725a, the second hollow portion 1725b, and the third hollow portion 1725c of the second shock-absorbing element. Specifically, the fourth hollow portion 1725d of the second shock-absorbing element is parallel to the second direction D2.

[0158] In this way, the Young's modulus of the second shock-absorbing element 172 can be reduced, thereby effectively restricting the movement range of the first movable portion 120 and slowing down the impact caused by the first movable portion 120.

[0159] Please continue to refer to Figure 4 and Figure 5 , the second surface 1722b of the second shock-absorbing element faces the second movable portion 130. When the second movable portion 130 rotates around the first direction D1 to a second movable portion limit first position, the second surface 1722b of the second shock-absorbing element 172 contacts the second movable portion 130 to restrict the movement range of the second movable portion 130.

[0160] It should be understood that when the second movable portion 130 rotates around the first direction D1 to the second movable portion limit first position, the second movable portion 130 also contacts the outer frame 111 and the base 112 of the fixed portion 110 to restrict the movement range of the second movable portion 130.

[0161] Through the outer frame 111, the base 112, and the second shock-absorbing element 172, the movement range of the second movable portion 130 around the first direction D1 can be more effectively restricted, and the impact caused by the second movable portion 130 can be slowed down.

[0162] When the second movable portion 130 rotates around the second direction D2 to a second movable portion limit second position, the second surface 1722b of the second shock-absorbing element 172 contacts the second movable portion 130 to restrict the movement range of the second movable portion 130.

[0163] It should be understood that when the second movable part 130 rotates around the second direction D2 to the second limit position of the second movable part, the second movable part 130 will also contact the base 112 of the fixed part 110 to limit the movement range of the second movable part 130.

[0164] Through the base 112 and the second shock-absorbing element 172, the movement range of the second movable part 130 can be more effectively restricted, and the impact caused by the second movable part 130 can be mitigated.

[0165] When the second movable part 130 is impacted and moves along the direction of the optical axis OA, the second surface 1722b of the second shock-absorbing element 172 contacts the second movable part 130 to limit the movement range of the second movable part 130. Through the second shock-absorbing element 172, the impact received by the second movable part 130 can be more effectively mitigated.

[0166] That is to say, the second shock-absorbing element 172 can limit the movement ranges of the first movable part 120 and the second movable part 130; in other words, the first movable part 120 and the second movable part 130 "share" the second stopping component 170. In this way, the number of components required for the optical element driving mechanism 100 can be reduced, and thus the effect of miniaturization can be achieved.

[0167] Please also refer to Figure 4 and Figure 8 . Figure 8 is a cross-sectional view of the optical element driving mechanism 100, the first optical element OE1, and the second optical element OE2 according to some embodiments of the present disclosure along the Figure 2 C-C' line.

[0168] As Figure 4 and Figure 8 shown, the first movable part 120, the first stopping component 160, and the second stopping component 170 are arranged along the optical axis OA, and the first driving component 140 drives the first movable part 120 to move relative to the fixed part 110 along the optical axis OA with a first driving force 100F. The first stopping component 160, the first driving force 100F, and the second stopping component 170 overlap each other along the optical axis OA.

[0169] In this way, the first stopping component 160 and the second stopping component 170 can directly receive the impact caused by the first driving force 100F, and thus can effectively limit the movement range of the first movable part 120. Moreover, instability caused by driving force offset can be avoided.

[0170] Please continue to refer to Figure 4 and Figure 8 , the second movable part 130 includes a second movable part body 131 and a hook part 132.

[0171] The second movable part body 131 and the hook part 132 contact the second optical element OE2, and the hook part 132 contacts the second optical element OE2, and the hook part 132 extends away from the second movable part body 131 along the optical axis OA from the second movable part body 131, so that the second optical element OE2 is located between the second movable part body 131 and the hook part 132.

[0172] In this way, the second optical element OE2 can be effectively fixed between the second movable part body 131 and the hook part 132 to prevent the second optical element OE2 from coming loose from the second movable part 130.

[0173] Please refer to Figure 9 and Figure 10 . Figure 9 is a cross-sectional view of the optical element driving mechanism 100, the first optical element OE1 and the second optical element OE2 along the Figure 2 D-D' line of Figure 10 is a cross-sectional view of the optical element driving mechanism 100, the first optical element OE1 and the second optical element OE2 along the Figure 2 E-E' line of

[0174] As Figure 9 and Figure 10 shown, in the direction perpendicular to the optical axis OA and parallel to the base 112 (which can be the second direction D2), the first movable part 120 and the outer frame 111 at least partially overlap, and the second movable part 130 and the outer frame 111 at least partially overlap.

[0175] In the direction perpendicular to the optical axis OA and perpendicular to the base 112 (which can be the first direction D1), the first movable part 120 and the outer frame 111 at least partially overlap, and the second movable part 130 and the outer frame 111 at least partially overlap.

[0176] As Figure 9 and Figure 10 shown, in the direction perpendicular to the optical axis OA and parallel to the base 112 (which can be the second direction D2), the first movable part 120 and the base 112 at least partially overlap, and the second movable part 130 and the base 112 at least partially overlap.

[0177] In the direction perpendicular to the optical axis OA and perpendicular to the base 112 (which can be the first direction D1), the first movable part 120 and the base 112 at least partially overlap, and the second movable part 130 and the base 112 at least partially overlap.

[0178] As Figure 9 and Figure 10As shown, in a direction perpendicular to the optical axis OA and parallel to the base 112 (which can be the second direction D2), the first driving component 140 and the outer frame 111 at least partially overlap (reference can be made to Figure 8 ), and the second driving component 150 and the outer frame 111 at least partially overlap.

[0179] In a direction perpendicular to the optical axis OA and perpendicular to the base 112 (which can be the first direction D1), the first driving component 140 and the outer frame 111 at least partially overlap, and the second driving component 150 and the outer frame 111 at least partially overlap.

[0180] As Figure 9 and Figure 10 shown, in a direction perpendicular to the optical axis OA and parallel to the base 112 (which can be the second direction D2), the first driving component 140 and the base 112 at least partially overlap (reference can be made to Figure 8 ), and the second driving component 150 and the base 112 at least partially overlap.

[0181] In a direction perpendicular to the optical axis OA and perpendicular to the base 112 (which can be the first direction D1), the first driving component 140 and the base 112 at least partially overlap, and the second driving component 150 and the base 112 at least partially overlap.

[0182] That is to say, the outer frame 111 and the base 112 can simultaneously accommodate the first movable part 120, the second movable part 130, the first driving component 140 and the second driving component 150; in other words, the first movable part 120, the second movable part 130, the first driving component 140 and the second driving component 150 "share" the outer frame 111 and the base 112. In this way, the number of components required for the optical element driving mechanism 100 can be reduced, and thus the miniaturization effect can be achieved.

[0183] Please continue to refer to Figure 9 and Figure 10 , the circuit component 180 is arranged on the base 112. In a direction perpendicular to the optical axis OA and parallel to the base 112 (which can be the second direction D2), the second movable part 130 and the circuit component 180 at least partially overlap.

[0184] In a direction perpendicular to the optical axis OA and perpendicular to the base 112 (which can be the first direction D1), the first movable part 120 and the circuit component 180 at least partially overlap, and the second movable part 130 and the circuit component 180 at least partially overlap.

[0185] As Figure 9 and Figure 10As shown, in a direction perpendicular to the optical axis OA and parallel to the base 112 (which can be the second direction D2), the second driving assembly 150 and the circuit assembly 180 at least partially overlap.

[0186] In a direction perpendicular to the optical axis OA and perpendicular to the base 112 (which can be the first direction D1), the first driving assembly 140 and the circuit assembly 180 at least partially overlap, and the second driving assembly 150 and the circuit assembly 180 at least partially overlap.

[0187] That is to say, the first driving assembly 140 and the second driving assembly 150 can receive current from the circuit assembly 180 to drive the first movable part 120 and the second movable part 130 respectively; in other words, the first movable part 120, the second movable part 130, the first driving assembly 140 and the second driving assembly 150 "share" the circuit assembly 180. In this way, the number of components required for the optical element driving mechanism 100 can be reduced, and thus the miniaturization effect can be achieved.

[0188] Generally speaking, the concave-convex structure, the hollow part and the outer shape of the first shock-absorbing element and the second shock-absorbing element of the optical element driving mechanism according to the embodiments of the present disclosure can mitigate the impact on the first movable part and the second movable part. Moreover, the optical element driving mechanism according to the embodiments of the present disclosure can "share" the outer frame, the base, the second stop assembly and the circuit assembly, so that the optical element driving mechanism according to the embodiments of the present disclosure can have the effects of miniaturization, light weight and improved stability, enabling the user to smoothly operate the optical element driving mechanism and obtaining a better imaging effect.
