[0074] The following describes the drive mechanism of an embodiment of the present invention. However, it will be readily apparent that the embodiments of the present invention provide many suitable inventive concepts and can be implemented in a wide range of specific contexts. The specific embodiments disclosed are merely illustrative of the use of the invention in a particular manner and are not intended to limit the scope of the invention.

[0075] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the relevant art and the background or context of this disclosure, and should not be interpreted in an idealized or overly formal manner, unless specifically defined herein.

[0076] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used in the embodiments are for illustrative purposes and not for limiting the present invention.

[0077] Please refer to the following first: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figures 1-3 The images show perspective views of a drive mechanism 100 according to an embodiment of the present invention from different angles. Figure 4 express Figure 1 Exploded view of the drive mechanism 100.

[0078] For example, the drive mechanism 100 of the present invention may be disposed inside an electronic device, such as a mobile phone, tablet computer or other portable electronic device.

[0079] from Figure 1 , Figure 2 , Figure 3 and Figure 4 As can be seen from the diagram, the drive mechanism 100 of this embodiment mainly includes a fixing part 10 (outer shell), a cover plate 20, a right-hand rotating arm 30, a left-hand rotating arm 30', a circuit board F, two coils C and C', two magnets M and M', two magnetic conductors K and K', a first right cover plate S1, a second right cover plate S2, a first left cover plate S1', and a second left cover plate S2'. The fixing part 10 is fixed inside the electronic device, and the cover plate 20 is attached to the fixing part 10. The first and second right cover plates S1 and S2, and the first and second left cover plates S1' and S2' are movably connected to the fixing part 10 through the right-hand rotating arm 30 and the left-hand rotating arm 30', respectively.

[0080] Specifically, the aforementioned right-hand rotating arm 30 and left-hand rotating arm 30' constitute a movable component within the drive mechanism 100. The right-hand rotating arm 30 is pivotally connected to the first right cover plate S1, the second right cover plate S2, and the fixed part 10, while the left-hand rotating arm 30' is pivotally connected to the first left cover plate S1', the second left cover plate S2', and the fixed part 10. It should be understood that when the right-hand rotating arm 30 and the left-hand rotating arm 30' rotate relative to the fixed part 10, they can respectively drive the first and second right cover plates S1 and S2 and the first and second left cover plates S1' and S2' to slide along the long axis direction (X-axis direction) of the fixed part 10, thereby serving as a shutter or aperture for a camera unit inside an electronic device.

[0081] In this embodiment, the aforementioned fixing part 10 has an opening 11 and an opening 12, wherein when the first and second right cover plates S1, S2 and the first and second left cover plates S1', S2' are located as follows: Figures 1-3When the device is in the open position as shown, external light can enter the electronic device through the perforation 21 on the cover plate 20 and the opening 11 on the fixing part 10. The light can then be projected onto an image sensor (not shown) inside the electronic device to generate a digital image. On the other hand, an optical rangefinder (not shown) located inside the electronic device can emit sensing light that passes through the aforementioned opening 12 and perforation 21 in sequence and exits the electronic device. After being reflected by an object, the sensing light can enter the electronic device through the perforation 21 and the aforementioned opening 12 and return to the aforementioned optical rangefinder to determine the distance between the object and the electronic device.

[0082] However, when the aforementioned first and second right shields S1 and S2 and the first and second left shields S1' and S2' (optical components) are driven by the right rotating arm 30 and the left rotating arm 30', they move from... Figures 1-3 When the open position shown is moved relative to the fixed part 10 to the closed position (e.g.) Figure 10 As shown), the aforementioned optical components will shield or partially shield the opening 11 to appropriately block light from entering the electronic device through the opening 11, thereby protecting the components inside the drive mechanism 100.

[0083] Please refer to the following as well. Figures 4-6 ,in Figure 5 express Figure 4 A perspective view of the fixing part 10 in the middle. Figure 6 This is a perspective view showing magnets M and M', coils C and C', and magnetic conductors K and K' respectively disposed in grooves R and R' of the fixing part 10. The coils C and C' can be electrically connected to the circuit board F disposed on the outside of the fixing part 10 via wires (not shown).

[0084] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, two grooves R and R' are formed inside the fixing part 10. The coil C and the magnetic conductor K are disposed in a first space R1 of the groove R during assembly, and the magnet M is disposed in a second space R2 of the groove R.

[0085] It should be noted that the aforementioned first space R1 is elongated, and the magnetic component K has a U-shaped structure. During assembly, the magnetic component K can pass through the coil C, and the magnetic component K and the coil C can be placed together in the first space R1 of the groove R.

[0086] Furthermore, the aforementioned second space R2 and magnet M are circular. During assembly, the hollow magnet M can be fitted onto the first rotating shaft H on the fixing part 10, and the first rotating shaft H can pass through the magnet M to prevent the magnet M from falling out of the second space R2.

[0087] Similarly, another set of coils C' and magnetic conductors K' are arranged in a first space R1' of groove R' during assembly, while magnet M is arranged in a second space R2' of groove R'.

[0088] It should be noted that the aforementioned first space R1' is elongated, while the magnetic component K' has a U-shaped structure. During assembly, the magnetic component K' can pass through the coil C', and the magnetic component K' and the coil C' can be placed together in the first space R1' of the groove R'.

[0089] Furthermore, the aforementioned second space R2' and magnet M' are circular. During assembly, the hollow magnet M' can be fitted onto the second rotating shaft H' on the fixing part 10, and the second rotating shaft H' can pass through the magnet M' to prevent the magnet M' from falling out of the second space R2'.

[0090] Please refer to the following: Figure 7 ,in Figure 7 This is a perspective view showing that the right rotating arm 30 and the left rotating arm 30' (movable components) are pivotally connected to the fixed part 10 via the first and second rotating shafts H and H', respectively.

[0091] from Figure 7 As can be seen, after installing magnets M and M', coils C and C', and magnetic conductors K and K' into the grooves R and R' inside the fixing part 10, the right-hand arm 30 and the left-hand arm 30' can be glued and fixed onto magnets M and M' respectively, and the first and second rotating shafts H and H' can pass through the right-hand arm 30 and the left-hand arm 30' respectively.

[0092] In this state, the aforementioned magnets M and M', coils C and C', and magnetic conductors K and K' can constitute a driving assembly. When current is passed through coil C, a magnetic field is generated that forces magnet M and right-hand rotating arm 30 to rotate together around the first axis H. Similarly, when current is passed through coil C', a magnetic field is generated that forces magnet M' and left-hand rotating arm 30' to rotate together around the second axis H'.

[0093] Please refer to the following as well. Figure 8 and Figure 9 ,in Figure 8 A perspective view showing the first pivot portions 31 and 31' on the right-hand rotating arm 30 and the left-hand rotating arm 30' passing through the first sliding grooves S11 and S11' on the first right cover plate S1 and the first left cover plate S1', respectively. Figure 9 A perspective view showing that the second pivots 32 and 32' on the right-hand arm 30 and the left-hand arm 30' pass through the second slides S21 and S21' on the second right cover plate S2 and the second left cover plate S2', respectively.

[0094] like Figure 8As shown, after the right-hand arm 30 and the left-hand arm 30' are respectively glued and fixed to the magnets M and M', the first pivot parts 31 and 31' on the right-hand arm 30 and the left-hand arm 30' can be slidably inserted into the first sliding grooves S11 and S11' on the first right cover plate S1 and the first left cover plate S1', respectively, so that the first right cover plate S1 and the first left cover plate S1' are pivotally connected to the right-hand arm 30 and the left-hand arm 30', respectively.

[0095] Next, as Figure 9 As shown, the second pivot portions 32 and 32' on the right rotating arm 30 and the left rotating arm 30' can be slidably inserted into the second sliding grooves S21 and S21' on the second right cover plate S2 and the second left cover plate S2', respectively, so that the second right cover plate S2 and the second left cover plate S2' can be pivotally connected to the right rotating arm 30 and the left rotating arm 30', respectively.

[0096] It is particularly important to note that the second pivot 32 of the right-hand rotating arm 30 is located between its first pivot 31 and the first rotating shaft H, while the second pivot 32' of the left-hand rotating arm 30' is located between its first pivot 31' and the second rotating shaft H'. Thus, when the right-hand rotating arm 30 and the left-hand rotating arm 30' rotate, not only can the aforementioned first pivots 31 and 31' slide within the first slide grooves S11 and S11 respectively, but the aforementioned second pivots 32 and 32' can also slide within the second slide grooves S21 and S21' respectively. The moving distance of the first right cover plate S1 and the first left cover plate S1' is greater than the moving distance of the second right cover plate S2 and the second left cover plate S2'.

[0097] In addition, from Figure 8 and Figure 9 It can be seen that when the optical components (first and second right shields S1 and S2 and first and second left shields S1' and S2') are in the open position, the first and second right shields S1 and S2 will cover the first rotating shaft H, and the first and second left shields S1' and S2' will cover the second rotating shaft H'. This can effectively reduce the size of the fixing part 10 in the Y-axis direction, so as to achieve miniaturization of the overall size of the drive mechanism 100.

[0098] Please see again Figure 10 ,in Figure 10 This diagram illustrates how, when current is applied to coils C and C', the first and second right shields S1 and S2, and the first and second left shields S1' and S2' are moved by the right and left rotating arms 30' and slide relative to the fixed part 10 to a closed position.

[0099] like Figure 10As shown, when current is passed through coils C and C', magnets M and M', and the right and left rotating arms 30 and 30' fixed on magnets M and M' will be rotated around the first and second rotating axes H and H' respectively by the magnetic field generated by coils C and C'. At this time, the first and second right shields S1 and S2 will be driven by the right rotating arm 30 and slide relative to the fixed part 10 toward the center of the opening 11, while the first and second left shields S1' and S2' will be driven by the left rotating arm 30' and slide relative to the fixed part 10 toward the center of the opening 11. At this time, the opening 11 on the fixed part 10 can be blocked by the optical components (the first and second right shields S1 and S2 and the first and second left shields S1' and S2') to block light from entering the electronic device through the opening 11.

[0100] In this embodiment, when the optical components (first and second right shields S1, S2 and first and second left shields S1', S2') move relative to the fixing part 10... Figure 10 When in the closed position shown, the first right cover S1 and the first left cover S1' will partially block the opening 11 respectively, and the two will contact each other to block light from entering the electronic device through the opening 11.

[0101] However, in other embodiments, only the first right cover plate S1 (or the first and second right cover plates S1 and S2) may be used to cover the opening 11, while omitting the aforementioned first and second left cover plates S1' and S2', and are not limited to those disclosed in this embodiment.

[0102] It should be noted that in this embodiment, the first and second right cover plates S1 and S2, and the first and second left cover plates S1' and S2' are elongated, while the fixing part 10 has a rectangular structure. The major axis of the first and second right cover plates S1 and S2, and the first and second left cover plates S1' and S2' are all parallel to the Y-axis, while the minor axis of the fixing part 10 is also parallel to the Y-axis.

[0103] In other words, the major axis direction of the first and second right cover plates S1, S2 and the first and second left cover plates S1', S2' is parallel to the minor axis direction (Y-axis direction) of the fixed part 10. Furthermore, since the aforementioned drive components (magnets M, M', coils C, C' and magnetic conductors K, K') and movable components (right rotating arm 30 and left rotating arm 30') do not protrude from the optical components (first and second right cover plates S1, S2 and first and second left cover plates S1', S2') in the minor axis direction (Y-axis direction) of the fixed part 10, the size of the fixed part 10 in its minor axis direction (Y-axis direction) can be minimized, thereby helping to reduce the volume of the drive mechanism 100.

[0104] Please refer to the following: Figure 11 ,in Figure 11 This is a sectional view of the drive mechanism 100.

[0105] like Figure 11 As shown, the aforementioned cover plate 20 is attached to the fixing part 10 and exposed on one side of the drive mechanism 100, wherein the second right cover plate S2 is located between the first right cover plate S1 and the cover plate 20 after assembly; similarly, the second left cover plate S2' will be located between the first left cover plate S1' and the cover plate 20 after assembly.

[0106] In addition, from Figure 11 As can be seen, a stepped structure is formed inside the fixing part 10, wherein the stepped structure includes a first inner sidewall 101 and a second inner sidewall 102. The aforementioned first right cover plate S1 slidably abuts against the aforementioned first inner sidewall 101, and the aforementioned second right cover plate S2 slidably abuts against the aforementioned second inner sidewall 102, and the length of the second right cover plate S2 is greater than the length of the first right cover plate S1.

[0107] Please see again Figure 12 ,in Figure 12 This is a cross-sectional view showing the first right cover S1 and the first left cover S1'.

[0108] from Figure 12 As can be seen, when the first and second right shields S1 and S2 and the first and second left shields S1' and S2' are driven by the right rotating arm 30 and the left rotating arm 30' and slide relative to the fixed part 10 to the closed position, the inclined surfaces S12 and S12' formed on the edges of the first right shield S1 and the first left shield S1' will come into contact with each other, so that the first right shield S1 and the first left shield S1' can partially overlap each other, so as to ensure that light will not pass through the gap between them, and at the same time, to prevent the first right shield S1 and the first left shield S1' from being damaged by collision.
