The outer frame 111 and the base 112 may be connected to each other and form an inner space to accommodate other elements of the optical element driving mechanism 100 or the first optical element OE1 and the second optical element OE2.

[0087] like Figure 2 As shown, a light ray L may be incident on the first optical element OE1 from the outside of the optical element region cam 100 via the second optical element OE2 along an optical axis OA (first direction D1).

[0088] The movable portion 120 may be connected to the first optical element OE1 and may move relative to the fixed portion 110. For example, the movable portion 120 may move relative to the fixed portion 110 along the optical axis OA, and the first optical element OE1 may move along the optical axis OA with the movable portion 120 relative to the fixed portion 110.

[0089] The driving component can drive the movable part 120 to move relative to the fixed part 110. The driving component can include a driving magnet (not shown) and a driving coil (not shown).

[0094] The anti-reflection component 150 may have a plate-like structure, and the anti-reflection component 150 may reduce abnormal reflection of stray light in the optical element driving mechanism 100 .

[0095] See also Figure 4 and Figure 5 . Figure 4 According to some embodiments of the present invention, the optical element driving mechanism 100, the first optical element OE1 and the second optical element OE2 are arranged along Figure 2 A cross-sectional view along the A-A' line. Figure 5 According to some embodiments of the present invention, the optical element driving mechanism 100, the first optical element OE1 and the second optical element OE2 are arranged along Figure 2 Cross-sectional view along line BB'.

[0096] like Figure 4 and Figure 5 As shown, the first optical element OE1 and the second optical element OE2 may be arranged along the optical axis OA, and the optical axis OA may pass through the center C1 of the first optical element OE1 and the center C2 of the second optical element OE2.

[0097] The first optical element OE1 may be connected to the movable portion 120, and the second optical element OE2 may be connected to the fixed portion 110.

[0105] In this way, it is possible to prevent unwanted light (eg, abnormal reflection of stray light in the optical element driving mechanism 100 ) from being incident on the first optical element OE1 and / or the second optical element OE2 , thereby improving the imaging quality.

[0106] Please continue reading Figure 4 and Figure 5 According to some embodiments of the present invention, the radius R1 of the first optical element OE1 may be different from the radius R2 of the second optical element OE2.

[0111] In this way, it is possible to prevent unwanted light (eg, abnormal reflection of stray light in the optical element driving mechanism 100 ) from being incident on the first optical element OE1 and / or the second optical element OE2 , thereby improving the imaging quality.

[0117] See also Figure 7 and Figure 8 , the thickness of the second circuit portion 132 may be different from the thickness of the first circuit portion 131 ; or in other words, the thickness of the first circuit portion 131 may be greater than the thickness of the second circuit portion 132 .

[0118] In detail, the first circuit portion 131 may have a double-layer metal structure, and the second circuit portion 132 may have a single-layer metal structure.

In other words, the number of metal layers of the first circuit portion 131 may be greater than the number of metal layers of the second circuit portion 132.

[0119] In this way, the space of the optical element driving mechanism 100 can be saved, thereby achieving a miniaturization effect, and a larger second optical element OE2 can also be used to achieve a better imaging effect.

[0120] See also Figure 7 and Figure 8 The anti-reflection component 150 may be disposed on the flat portion 1321 of the second circuit portion 132 , and the reflectivity of the surface of the anti-reflection component 150 may be lower than the reflectivity of the surface of the first circuit portion 131 and the reflectivity of the surface of the second circuit portion 132 .

[0121] According to some embodiments of the present invention, the anti-reflection component 150 may be a light absorbing element with light absorbing properties, or may be coated with a material with light absorbing properties, such as ink (eg, dark ink, black ink, etc.).

[0122] In this way, it is possible to prevent unwanted light (eg, abnormal reflection of stray light in the optical element driving mechanism 100 ) from being incident on the first optical element OE1 and / or the second optical element OE2 , thereby improving the imaging quality.

[0123] like Figure 7 and Figure 8 As shown, the circuit assembly 130 can be connected to the base 112 of the fixed portion 110 via the first connecting element 141 and the second connecting element 142.

[0130] In this way, the structure of the optical element driving mechanism can be made more stable, and the thickness of the first connecting element 141 and the second connecting element 142 can be made more stable.

[0131] Please go back Figure 6 The connection assembly 140 may further include a positioning portion 143. The positioning portion 143 may be fixedly connected to the fixed portion 110.
