Figure 1 As shown, in some embodiments of this utility model, an optical element driving mechanism 100 can be installed in an electronic device 1 for taking pictures or videos.

Figure 1 The positional and size relationship between the optical element driving mechanism 100 and the electronic device 1 shown is merely an example and not a limitation on the positional and size relationship between the optical element driving mechanism 100 and the electronic device 1. In practice, the optical element driving mechanism 100 can be installed in different positions within this electronic device 1 according to different needs.

[0073] Please see Figure 2 and Figure 3 . Figure 2 This is a schematic diagram of an optical element driving mechanism 100 and an optical element OE according to some embodiments of the present invention. Figure 3 This is an exploded view of the optical element driving mechanism 100 and the optical element OE according to some embodiments of the present invention.

[0074] The optical element driving mechanism 100 may include a fixed part 110, a movable part 120, a driving assembly 130, a conductive pin assembly 140, a first connecting element 150, and a second connecting element 160.

[0075] The fixing part 110 extends along a first direction D1. The fixing part 110 may include an outer frame 111 and a base 112. The outer frame 111 is disposed on the base 112, and the outer frame 111 and the base 112 can be connected to each other to form an internal space to accommodate other components of the optical element drive mechanism 100 and the optical element OE.

[0076] The movable part 120 can be connected to the optical element OE, and the movable part 120 can move relative to the fixed part 110. For example, the movable part 120 can move relative to the fixed part 110 along a first direction D1, and the optical element OE can move along the first direction D1 with the movable part 120 relative to the fixed part 110.

[0077] The first drive assembly 130 can drive the movable part 120 to move relative to the fixed part 110. The first drive assembly 130 may include a piezoelectric element 131 and a drive element 132. The drive element 132 can apply a voltage to the piezoelectric element 131 to drive the piezoelectric element 131 to extend or shorten, thereby driving the movable part 120 and the optical element OE.

[0078] The conductive pin assembly 140 is fixed to the base 112 of the fixing part 110. The conductive pin assembly 140 includes a conductive material, and the optical element OE also includes a conductive material. Therefore, when the optical element OE contacts the conductive pin assembly 140, the conductive pin assembly 140 and the optical element OE form an electrical circuit, thereby determining the position of the optical element OE.

[0079] Please see Figure 4 , Figure 4 This is a schematic diagram of an optical element driving mechanism 100 and an optical element OE according to some embodiments of the present invention, wherein the outer frame 111 is omitted. Figure 4 As shown, the conductive pin assembly 140 includes a first conductive pin assembly 141 and a second conductive pin assembly 142. The first conductive pin assembly 141 and the second conductive pin assembly 142 are arranged along a first direction D1.

[0080] like Figure 4 As shown, the first conductive pin assembly 141 includes two first conductive pins 1411. Each first conductive pin 1411 includes a first conductive pin arm 1411a, a first conductive pin foot 1411b, and a first conductive pin hook 1411c. The first conductive pin arm 1411a is connected to the first conductive pin foot 1411b, and the first conductive pin hook 1411c is formed on the first conductive pin foot 1411b.

[0081] The first conductive pin arm 1411a has a pre-pressure, which allows it to tilt downwards, making it non-parallel to the fixing part 110. In other words, the first conductive pin arm 1411a is not parallel to the first direction D1. Specifically, an angle can be formed between the first conductive pin arm 1411a and the fixing part 110, and this angle is less than 10 degrees. According to some embodiments of this invention, the angle between the first conductive pin arm 1411a and the fixing part 110 is less than 5 degrees.

[0082] According to some embodiments of the present invention, this downward pressure (pre-pressure) should be between 30% and 50% of the driving force of the drive assembly 130 along the first direction D1, so as to avoid the optical element OE having difficulty "lifting" the first conductive pin arm 1411a, thereby hindering the movement of the movable part 120 and the optical element OE. According to some embodiments of the present invention, this downward pressure (pre-pressure) should be less than 30% of the driving force of the drive assembly 130 along the first direction D1.

[0083] The first conductive pin foot 1411b can extend from the first conductive pin arm 1411a along a second direction D2 perpendicular to the first direction D1, and the first conductive pin foot 1411b is exposed in the base 112. The first conductive pin hook 1411c can fix the first conductive pin 1411 to the base 112.

[0084] like Figure 4 As shown, the second conductive pin assembly 142 includes two second conductive pins 1421. Each second conductive pin 1421 includes a second conductive pin arm 1421a, a second conductive pin foot 1421b, and a second conductive pin hook 1421c. The second conductive pin arm 1421a is connected to the second conductive pin foot 1421b, and the second conductive pin hook 1421c is formed on the second conductive pin foot 1421b.

[0085] The second conductive pin arm 1421a has a pre-pressure, which allows it to tilt downwards, making it non-parallel to the fixing part 110. In other words, the second conductive pin arm 1421a is not parallel to the first direction D1. Specifically, an angle can be formed between the second conductive pin arm 1421a and the fixing part 110, and this angle is less than 10 degrees. According to some embodiments of this invention, the angle between the second conductive pin arm 1421a and the fixing part 110 is less than 5 degrees.

[0086] According to some embodiments of the present invention, this downward pressure (pre-pressure) should be between 30% and 50% of the driving force of the drive assembly 130 along the first direction D1, so as to avoid the optical element OE having difficulty "lifting" the second conductive pin arm 1421a, thereby hindering the movement of the movable part 120 and the optical element OE. According to some embodiments of the present invention, this downward pressure (pre-pressure) should be between 30% of the driving force of the drive assembly 130 along the first direction D1.

[0087] The second conductive pin foot 1421b can extend from the second conductive pin arm 1421a along a second direction D2 perpendicular to the first direction D1, and the second conductive pin foot 1421b is exposed in the base 112. The second conductive pin hook 1421c can fix the second conductive pin 1421 to the base 112.

[0088] Please see Figure 4 The first conductive pin arm 1411a and the second conductive pin arm 1421a may extend in generally opposite directions. For example, the first conductive pin arm 1411a and the second conductive pin arm 1421a may extend away from each other.

[0089] Please continue reading. Figure 4The optical element OE includes an optical element conductive pin opening OEa. The optical element conductive pin opening OEa corresponds to the first conductive pin arm 1411a and the second conductive pin arm 1421a. Therefore, in some cases (see the following description), the first conductive pin arm 1411a and the second conductive pin arm 1421a may not be in contact with the optical element OE.

[0090] exist Figure 4 In this embodiment, the optical element OE approaches and "pushes up" the first conductive pin arm 1411a (the first conductive pin arm 1411a moves along the second direction D2), causing the optical element OE and the first conductive pin arm 1411a to come into contact with each other, and the two first conductive pin arms 1411a can be electrically connected to each other through the optical element OE, thereby forming a first electrical circuit. Therefore, when the sensor (not shown) or the controller (not shown) receives the first signal emitted by the first electrical circuit, it can be determined that the optical element OE is located as follows: Figure 4 The first position P1 is shown.

[0091] When the optical element OE is in the first position P1, the conductive pin opening OEa of the optical element corresponds to the second conductive pin arm 1421a (overlapping with each other in the second direction D2), therefore the two second conductive pin arms 1421a do not contact the optical element OE. Consequently, the two second conductive pin arms 1421a do not form an electrical circuit. Therefore, the sensor (not shown) or controller (not shown) will not receive the signal emitted by the second conductive pin arms 1421a being electrically connected to the optical element OE.

[0092] Please see Figure 5 , Figure 5 This is a schematic diagram of an optical element driving mechanism 100 and an optical element OE according to some embodiments of the present invention, wherein the outer frame 111 is omitted.

[0093] exist Figure 5 In this embodiment, the optical element OE approaches and "pushes up" the second conductive pin arm 1421a (the second conductive pin arm 1421a moves along the second direction D2), causing the optical element OE and the second conductive pin arm 1421a to come into contact with each other, and the two second conductive pin arms 1421a can be electrically connected to each other through the optical element OE, thereby forming a second electrical circuit. Therefore, when the sensor (not shown) or the controller (not shown) receives the second signal emitted by the second electrical circuit, it can be determined that the optical element OE is located as shown in the second direction D2. Figure 5 The first position shown is P2.

[0094] When the optical element OE is in the second position P2, the two first conductive pin arms 1411a are not in contact with the optical element OE. Therefore, the two first conductive pin arms 1411a do not form an electrical circuit. Consequently, the sensor (not shown) or controller (not shown) will not receive signals emitted by the first conductive pin arms 1411a being electrically connected to the optical element OE.

[0095] Please continue reading. Figure 5 The first conductive pin hook portion 1411c and the second conductive pin hook portion 1421c are exposed in the fixing portion 110 and the base 112. The second connecting element 160 can cover the first conductive pin hook portion 1411c and the second conductive pin hook portion 1421c to connect the first conductive pin hook portion 1411c and the second conductive pin hook portion 1421c to the base 112 of the fixing portion 110.

[0096] Please see Figure 4 and Figure 5 Specifically, when the optical element OE contacts the first conductive pin arm 1411a of the conductive pin 141 of the conductive pin assembly 140, the optical element OE will not contact the second conductive pin arm 1421a of the conductive pin 142 of the conductive pin assembly 140. At this time, the sensor (not shown) or controller (not shown) will only receive the first signal emitted by the first electrical circuit formed by the first conductive pin arm 1411a, and will not receive the second signal. Therefore, it can be determined that the optical element OE is located as follows: Figure 4 The first position P1 is shown.

[0097] However, according to some embodiments of the present invention, when the optical element OE contacts the first conductive pin string arm 1411a of the conductive pin 141 of the conductive pin assembly 140, the drive assembly 130 will continue to drive the movable part 120 to move in the positive (+) direction of the first direction D1 for a period of time before stopping the drive, so as to ensure that the optical element OE is located in the first position P1.

[0098] When the optical element OE contacts the second conductive pin arm 1421a of the conductive pin 142 of the conductive pin assembly 140, the optical element OE will not contact the first conductive pin arm 1411a of the conductive pin 141 of the conductive pin assembly 140. At this time, the sensor (not shown) or controller (not shown) will only receive the second signal emitted by the second electrical circuit formed by the second conductive pin arm 1421a, and will not receive the first signal. Therefore, it can be determined that the optical element OE is located as follows: Figure 5 The second position P2 is shown.

[0099] However, according to some embodiments of the present invention, when the optical element OE contacts the second conductive pin arm 1421a of the conductive pin 142 of the conductive pin assembly 140, the drive assembly 130 will continue to drive the movable part 120 to move in the opposite direction (-direction) of the first direction D1 for a period of time before stopping the drive, so as to ensure that the optical element OE is located in the second position P2.

[0100] When the optical element OE does not contact the first conductive pin string arm 1411a of the conductive pin 141 of the conductive pin assembly 140, nor the second conductive pin string arm 1421a of the conductive pin 142, the drive assembly drives the movable part 120 to move in the forward or reverse direction along the first direction D1.

[0101] Please see Figure 6 , Figure 6 The optical element driving mechanism 100 and the optical element OE along the path according to some embodiments of this utility model are described. Figure 2 A sectional view of line A-A'.

[0102] like Figure 6 As shown, the movable part 120 is located between the first conductive pin arm 1411a and the second conductive pin arm 1421a and the base 112 of the fixed part 110. That is, when assembling the optical element drive mechanism 100, the movable part 120 can be installed first and then the conductive pin assembly 140 can be installed.

[0103] The active part 120 includes a clamping element 121 that clamps the piezoelectric element 131 and fixes the optical element OE to the piezoelectric element 131.

[0104] The outer frame 111 includes an outer frame opening 111a, which corresponds to the conductive pin assembly 140 (e.g., overlapping in the second direction D2). Therefore, the conductive pin assembly 140 does not contact the outer frame 111. The outer frame 111 also includes an outer frame surface 111b facing the conductive pin assembly 140. The outer frame surface 111b includes electrically insulating portions. Therefore, electrical connection between the outer frame 111 and the conductive pin assembly 140 can be effectively prevented.

[0105] According to some embodiments of the present invention, the conductive pin assembly 140 also includes electrically insulating portions. For example, in one embodiment, the surfaces of the first conductive pin arm 1411a and the second conductive pin arm 1421a facing the outer frame surface 111b may have electrically insulating portions. For example, in one embodiment, the surfaces of the first conductive pin arm 1411a and the second conductive pin arm 1421a away from the outer frame surface 111b may have electrically insulating portions; however, the portions of the first conductive pin arm 1411a and the second conductive pin arm 1421a that contact the optical element OE are not electrically insulating. Therefore, unwanted electrical connections between the conductive pin assembly 140 and other components can be effectively avoided.

[0106] Please continue reading. Figure 6 The optical element OE also includes an optical element connection opening OEb. The first connecting element 150 fixes the optical element OE to the clamping element 121 of the movable part 120 via the optical element connection opening OEb. It should be noted that the conductive pin assembly 140 does not extend into the optical element connection opening OEb, that is, in the first direction D1, the conductive pin assembly 140 does not overlap with the optical element connection opening OEb.

[0107] Please see Figure 7 , Figure 7 The optical element driving mechanism 100 and the optical element OE along the path according to some embodiments of this utility model are described. Figure 2 A cross-sectional view of line B-B'.

[0108] like Figure 7 As shown, the clamping element 121 is located between a first wall 110a and a second wall 110b of the fixed portion 110 to limit the range of motion of the movable portion 120.

[0109] Please see Figure 8 , Figure 8 This is a schematic diagram of the conductive pin foot and conductive pin hook according to some embodiments of the present utility model.

[0110] like Figure 8 As shown, the base 112 of the fixing part 110 includes a plurality of hook stop portions 112a. The hook stop portions 112a correspond to the first conductive pin hook portion 1411c and the second conductive pin hook portion 1421c, so as to connect the first conductive pin hook portion 1411c and the second conductive pin hook portion 1421c to the base 112 of the fixing part 110.

[0111] In summary, since the embodiments of this invention can determine the positions of the movable part 120 and the optical element OE through the conductive pin assembly 140, the optical element driving mechanism 100 of this invention does not need to use a sensing module to sense the positions of the movable part 120 and the optical element OE. Therefore, the embodiments of this invention can have the advantages of reducing manufacturing costs, reducing the length of the optical element driving mechanism 100 (along the first direction D1), and reducing the thickness of the optical element driving mechanism 100 (along the second direction D2).
