[0049] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0050] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0051] Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts.

[0052] Furthermore, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the present specification may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description herein.

[0053] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings lying behind each term.

[0054] Figure 1 It is a three-dimensional diagram of the variable aperture device of the present invention. Figure 2 The explosion of the variable aperture device of the present invention Figure 1 . Figure 3 The explosion of the variable aperture device of the present invention Figure 2 .

[0055] like Figures 1 to 3 As shown, the present invention discloses a variable aperture device, comprising a housing 10, a base 20, and a conductive terminal 21. The housing 10 and base 20 are provided with a light-transmitting hole 30, and the conductive terminal 21 is mounted on the base 20. The variable aperture device further comprises a shape memory wire 40, a terminal connecting portion 50, a movable portion 60, and a driven portion 70. One end of the shape memory wire 40 is connected to the terminal connecting portion 50, and the movable portion 60 is connected to the base 20 via a rotating shaft 22. One side of the rotating shaft 22 of the movable portion 60 is connected to the other end of the shape memory wire 40, and the other side of the rotating shaft 22 of the movable portion 60 is connected to the elastic structure of the terminal connecting portion 50. The elastic structure here can preferably be a spring 53.

[0056] The terminal connection portion 50 is thus mounted on the conductive terminal 21, and the shape memory wire 40, the terminal connection portion 50, and the movable portion 60 are connected to form a circuit path. One end of the conductive terminal 21 is fixed to the base 20, while the other end extends downward from the base 20. Multiple raised heat rivets (or welding portions) 23 are distributed around one end of the conductive terminal 21 to connect the conductive terminal 21 and the terminal connection portion 50, maintaining a stable electrical connection.

[0057] When power is off, the shape-memory wire 40 is in its natural state, and the spring 53 pulls the movable portion 60 to cover the light-transmitting aperture. When a certain current is applied, the shape-memory wire 40 contracts, stretching the spring 53 and partially revealing the light-transmitting aperture (a small aperture). Alternatively, when a certain current is applied, the shape-memory wire 40 contracts, stretching the spring 53 and revealing the entire light-transmitting aperture (a large aperture).

[0058] Preferably, the variable aperture device further includes a driven portion 70. The movable portion 60 and the driven portion 70 are rotatably connected via a connecting portion 90. One end of the connecting portion 90 is rotatably connected to the movable portion 60. A sliding groove 71 is defined at one end of the driven portion 70, and a protrusion 91 is provided at the other end of the connecting portion 90. The protrusion 91 is mounted within the sliding groove 71. As the movable portion 60 rotates, the protrusion 91 slides along the sliding groove 71. The sliding groove 71 is preferably L-shaped. Thus, the movable portion 60 rotates, driving the driven portion 70 to form a variable aperture structure.

[0059] Furthermore, the variable aperture device also includes a support portion 80, one end of which is rotatably connected to one end of the movable portion 60 and fixed to the base 20, for supporting the movable portion 60. The support portion 80 is connected to the movable portion 60 via a rotating shaft 22. The support portion 80 is located between the movable portion 60 and the base 20, effectively preventing frictional debris and friction between the movable portion 60 and the base 20.

[0060] Furthermore, the other end of the shape memory wire 40 is connected to the movable portion 60. Here, the terminal connection portion 50 preferably includes a first terminal connection portion 51 and a second terminal connection portion 52 connected to each other, connecting one end of the shape memory wire 40 to the second terminal connection portion 52, and the elastic piece 53 of the first terminal connection portion 51 is connected to one end of the movable portion 60.

[0061] like Figure 3 As shown in the figure, the conductive terminal 21 is connected to the first terminal connecting part 51 and the second terminal connecting part 52 in the A area on the base 20 respectively, and the raised thermal rivet column (or welding part) 23 can ensure that the conductive terminal 21 and the first terminal connecting part 51 and the second terminal connecting part 52 are stably electrically connected.

[0062] Specifically, a first bend 511 is provided on the outer side of the second terminal connection portion 52, and one end of the shape memory wire 40 is connected to the first bend 511. Similarly, a second bend 61 is provided on the outer side of the movable portion 60, and the other end of the shape memory wire 40 is connected to the second bend 61.

[0063] In particular, the movable part 60 includes a first arc-shaped main body part 62, and the driven part 70 includes a second arc-shaped main body part 72. The first arc-shaped main body part 62 and the second arc-shaped main body part 72 are overlapped correspondingly. When the movable part 60 and the driven part 70 move relative to each other, an aperture with a variable diameter is formed between the first arc-shaped main body part 61 and the second arc-shaped main body part 72.

[0064] According to the above structural description, in the variable aperture device of the present invention, a circuit path is formed by connecting the shape memory wire 40 via the terminal connection portion 50. Current drives the shape memory wire 40, causing the movable portion 60 to move. The shape memory wire 40 is elastic, and in addition to providing a restoring force, it also serves as a current conducting component. The shape memory wire 40, movable portion 60, and driven portion 70 form a stable and controllable aperture structure.

[0065] When the shape memory wire 40 recovers its natural length, the movable part 60 rotates, and the connecting part 90 slides inward along the upper slide groove 71 of the driven part 70 until it slides to the innermost first end 711. The movable part 60 and the driven part 70 rotate with each other until they rotate to an overlapping closed state, that is, the entire aperture is in a closed state.

[0066] When the shape memory wire 40 is energized and shortened, the movable portion 60 rotates, and the connecting portion 90 slides outward along the upper groove 71 of the driven portion 70 until it reaches the outermost second end 712. The movable portion 60 and the driven portion 70 rotate relative to each other, and the aperture gradually opens and widens until it reaches a fully open state. The shape memory wire 40 provides both the driving mechanism and the restoring force.

[0067] On the basis of the above structure, the present invention further provides a photographic device, which includes the variable aperture device as described above.

[0068] On the basis of the above structure, the present invention further provides an electronic device, which includes the above-mentioned camera device.

[0069] In summary, the variable aperture device and its associated camera and electronic device of the present invention can shield the lens, prevent privacy leaks, and provide both small and large aperture modes. It utilizes a shape memory wire to form a circuit path, and current drives the shape memory wire to cause the movable portion to move.

[0070] While the above description has been given of the best embodiments of the present invention with reference to the accompanying drawings, the present invention is not limited to these embodiments and various adjustments can be made based on the scope and content of the patent application with the knowledge of the technology.
