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 portion 120 is located at a first extreme position, the first shock absorbing element 162 contacts the first contact element 161 to limit the range of motion of the first movable portion 120.

[0121] According to some embodiments of the present disclosure, the Young's modulus of the first contact element 161 is different from the Young's modulus of the first shock absorbing element 162. According to some embodiments of the present disclosure, the Young's modulus of the first fixing element 163 is different from the Young's modulus of the first shock absorbing element 162.

[0125] The first shock absorbing element first surface 1622a is located on the first shock absorbing element body 1621, and the first shock absorbing element first surface 1622a faces the first contact element 161. In detail, the first shock absorbing element first surface 1622a is substantially perpendicular to the optical axis OA.

[0126] The first shock absorbing element second surface 1622b is located on the first shock absorbing element body 1621, and the first shock absorbing element second surface 1622b is adjacent to the first shock absorbing element first surface 1622a. The first shock absorbing element second surface 1622b is not parallel to the first shock absorbing element first surface 1622a. In detail, the first shock absorbing element second surface 1622b is perpendicular to the second direction D2.

[0127] The first shock absorbing element third surface 1622c is located on the first shock absorbing element body 1621, and the first shock absorbing element third surface 1622c is adjacent to the first shock absorbing element first surface 1622a and the first shock absorbing element second surface 1622b. The first shock absorbing element third surface 1622c is not parallel to the first shock absorbing element first surface 1622a and the first shock absorbing element second surface 1622b. Specifically, the first shock absorbing element third surface 1622c is perpendicular to the first direction D1.

[0128] The first shock absorbing element fourth surface 1622d is located on the first shock absorbing element body 1621, and the first shock absorbing element fourth surface 1622d is adjacent to the first shock absorbing element first surface 1622a and the first shock absorbing element third surface 1622c. The first shock absorbing element fourth surface 1622d is substantially parallel to the first shock absorbing element second surface 1622b; however, the first shock absorbing element fourth surface 1622d and the first shock absorbing element second surface 1622b face opposite directions. Specifically, the first shock absorbing element fourth surface 1622d is perpendicular to the second direction D2.

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

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

[0138] Please also see Figure 4 , Figure 5 The second contact element 171 is located on the first movable 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 movable portion 120 is located at a second extreme position, the second shock absorbing element 172 contacts the second contact element 171 to limit the range of motion of the first movable portion 120.

[0139] According to some embodiments of the present disclosure, the Young's modulus of the second contact element 171 is different from the Young's modulus of the second shock absorbing element 172.

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

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

[0146] The second shock absorbing element first surface 1722a extends along the second direction D2 away from the second shock absorbing element body 1721, and the second shock absorbing element second surface 1722b also extends along the second direction D2 away from the second shock absorbing element body 1721. However, the extension direction of the second shock absorbing element first surface 1722a is opposite to the extension direction of the second shock absorbing element second surface 1722b. When viewed from the first direction D1, the second shock absorbing element 172 may have a substantially Z-shape (see FIG. Figure 4 ).

[0147] In this way, the Young's modulus of the second shock absorbing element 172 can be reduced, thereby effectively limiting the movement range of the first movable portion 120 and alleviating the impact caused by the first movable portion 120 .

[0148] The second shock absorbing element third surface 1722c is located on the second shock absorbing element body 1721, and the second shock absorbing element third surface 1722c is adjacent to the second shock absorbing element first surface 1722a.

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

The second shock absorbing element first fixing surface 1723a faces the second fixing element 173, and the second shock absorbing element second fixing surface 1723b faces the second shock absorbing element first fixing surface 1723a. The second shock absorbing element first fixing surface 1723a and the second shock absorbing element second fixing surface 1723b extend from the second shock absorbing element third surface 1722c along the first direction D1, so that an accommodation space is defined between the second shock absorbing element first fixing surface 1723a and the second shock absorbing element second fixing surface 1723b.

[0151] 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 is provided with a connecting element 190, 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. In addition, 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 second shock absorbing element concavo-convex structure 1724 is formed on the second shock absorbing element first surface 1722 a , and when the first movable portion 120 is located at the second limit position, the second shock absorbing element concavo-convex structure 1724 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 limiting the movement range of the first movable portion 120 and alleviating the impact caused by the first movable portion 120 .

[0154] The second shock absorbing element first hollow portion 1725a is formed on the second shock absorbing element first surface 1722a on the second shock absorbing element body 1721, and the second shock absorbing element first hollow portion 1725a has a long strip structure. The second shock absorbing element first hollow portion 1725a penetrates the second shock absorbing element body 1721, and the second shock absorbing element first hollow portion 1725a is parallel to the optical axis OA.

[0155] The second shock absorbing element second hollow portion 1725b is formed on the second shock absorbing element second surface 1722b on the second shock absorbing element body 1721, and the second shock absorbing element second hollow portion 1725b has a long strip structure. The second shock absorbing element second hollow portion 1725b penetrates the second shock absorbing element body 1721 and reaches the second shock absorbing element first surface 1722a, and the second shock absorbing element second hollow portion 1725b is parallel to the second shock absorbing element first hollow portion 1725a. In detail, the second shock absorbing element second hollow portion 1725b is parallel to the optical axis OA.

[0156] The third hollow portion 1725c of the second shock absorbing element has a long strip structure. The third hollow portion 1725 penetrates the second shock absorbing element body 1721, and the third hollow portion 1725c of the second shock absorbing element is perpendicular to the first hollow portion 1725a of the second shock absorbing element and the second hollow portion 1725b of the second shock absorbing element. In detail, 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 second shock absorbing element on the second shock absorbing element body 1721, and the fourth hollow portion 1725d of the second shock absorbing element has a long strip structure. The fourth hollow portion 1725d of the second shock absorbing element runs through the second shock absorbing element body 1721, and the second hollow portion 1626b of the first shock absorbing element is perpendicular to the first hollow portion 1725a of the second shock absorbing element, the second hollow portion 1725b of the second shock absorbing element, and the third hollow portion 1725c of the second shock absorbing element. In detail, 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 limiting the movement range of the first movable portion 120 and alleviating the impact caused by the first movable portion 120 .

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

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

[0161] The outer frame 111 , the base 112 and the second shock absorbing element 172 can more effectively limit the movement range of the second movable portion 130 around the first direction D1 , and can mitigate the impact caused by the second movable portion 130 .

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

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

[0164] The base 112 and the second shock absorbing element 172 can more effectively limit the movement range of the second movable portion 130 , and can mitigate the impact caused by the second movable portion 130 .

[0165] When the second movable portion 130 is impacted and moves along the optical axis OA, the second shock absorbing element second surface 1722b of the second shock absorbing element 172 contacts the second movable portion 130 to limit the movement range of the second movable portion 130. The second shock absorbing element 172 can more effectively mitigate the impact on the second movable portion 130.

[0166] That is, the second shock absorbing element 172 can limit the range of motion of the first movable portion 120 and the second movable portion 130; in other words, the first movable portion 120 and the second movable portion 130 "share" the second stopper assembly 170. In this way, the number of components required for the optical element driving mechanism 100 can be reduced, thereby achieving a miniaturized effect.

[0167] Please also see Figure 4 and Figure 8 . Figure 8 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 are arranged along Figure 2 Cross-sectional view along line C-C'.

The first stopper assembly 160, the first driving force 100F, and the second stopper assembly 170 overlap each other along the optical axis OA.

[0169] In this way, the first stopper assembly 160 and the second stopper assembly 170 can directly receive the impact caused by the first driving force 100F, thereby effectively limiting the movement range of the first movable portion 120. In addition, the instability caused by the biased driving force can be avoided.

[0170] Please continue reading Figure 4 and Figure 8 The second movable portion 130 includes a second movable portion body 131 and a hook portion 132 .

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

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

In this way, the number of components required for the optical element driving mechanism 100 can be reduced, thereby achieving a miniaturized effect.

[0183] Please continue reading Fig. 9 and Fig.10 The circuit assembly 180 is disposed on the base 112. In a direction perpendicular to the optical axis OA and parallel to the base 112 (which may be the second direction D2), the second movable portion 130 and the circuit assembly 180 at least partially overlap.
