[0045] Figure 1According to one or more embodiments of the present invention, a three-dimensional schematic diagram of a dual-screen device 100 is depicted. The dual-screen device 100 includes a base 110, a first screen 130a, and a second screen 130b, wherein the first screen 130a and the second screen 130b are coaxially pivoted to the base 110, and the base 110 is disposed between the first screen 130a and the second screen 130b, so that the first screen 130a and the second screen 130b can be selectively rotated relative to the base 110. Specifically, the first screen 130a and the second screen 130b have display panels (such as touch panels), wherein the display surfaces of the first screen 130a and the second screen 130b face different directions (such as opposite directions), so that the first screen 130a and the second screen 130b display images or provide operations for users in different directions, but the present invention is not limited thereto. In addition, the base 110 is also used to selectively limit the first screen 130a and the second screen 130b, so that the first screen 130a and the second screen 130b can selectively rotate relative to each other and maintain a spaced separation, thereby preventing the first screen 130a and the second screen 130b from colliding with each other and causing damage. In practical applications, the first screen 130a and the second screen 130b can be rotated relative to the base 110 by force, and different users can adjust the elevation angles of the first screen 130a and the second screen 130b according to their needs for easy viewing. In addition, the base 110 of the dual-screen device 100 also includes a first connecting arm 160a and a second connecting arm 160b, and the back of the first screen 130a is rotatably connected to the base 110 via the first connecting arm 160a, and the back of the second screen 130b is rotatably connected to the base 110 via the connecting arm 160b. The mechanism and structure of the base 110 for limiting the first screen 130a and the second screen 130b will be described in detail in the following paragraphs. Here, only the function of the base 110 is introduced to avoid making the content of this paragraph too complicated.

[0046] Figures 2 to 4 A schematic side view of a dual-screen device 100 is shown according to one or more embodiments of the present invention. Figures 2 to 4 In the embodiment, the base 110 is disposed between the first screen 130a and the second screen 130b, and the first screen 130a and the second screen 130b have their display surfaces facing the front and are facing away from the base 110. Figures 2 to 4 The first screen 130a and the second screen 130b are located at different elevation angles. Figure 2 In the embodiment, the display surface of the first screen 130a faces upward, and the display surface of the second screen 130b faces leftward, wherein the first screen 130a and the second screen 130b are separated by a distance D1, and the first connecting arm 160a and the second connecting arm 160b form an angle θ1. Figure 3In the embodiment, the display surfaces of the first screen 130a and the second screen 130b face the upper left side and the upper right side respectively, wherein the first screen 130a and the second screen 130b are separated by a distance D2, and the first connecting arm 160a and the second connecting arm 160b form an angle θ2. Figure 4 In the embodiment, the display surface of the first screen 130a faces right, and the display surface of the second screen 130b faces upward, wherein the first screen 130a and the second screen 130b are separated by a distance D3, and the first connecting arm 160a and the second connecting arm 160b form an angle θ3. Figures 2 to 4 It can be seen that the first screen 130a and the second screen 130b can be rotated to different elevation angles respectively, and the first screen 130a and the second screen 130b are separated at each elevation angle without touching each other or colliding with each other due to excessive rotation force.

[0047] Please refer to Figure 5 , Figure 5 According to one or more embodiments of the present invention, Figure 1 An exploded view of some components of the dual screen device 100 is shown. Figure 5 The components shown are separated, but in actual use, the components are combined. A person skilled in the art of the present disclosure can follow the instructions. Figure 5 , the specification and other drawings to understand the assembly state of each component after combination. In some embodiments of the present invention, the base 110 includes a limiting shaft 111, and the limiting shaft 111 has a rotatable first rotating part 111a and a rotatable second rotating part 111b, the first rotating part 111a and the second rotating part 111b are respectively located at opposite ends of the long axis L of the limiting shaft 111, and the first rotating part 111a and the second rotating part 111b rotate relative to the long axis L with the long axis L of the limiting shaft 111 as the center axis. Specifically, the first rotating part 111a and the second rotating part 111b are respectively connected to the two ends of the limiting shaft 111 via bearings, but the present invention is not limited thereto. In one or more embodiments of the present invention, the first screen 130a is connected to the first rotating part 111a, and the second screen 130b is connected to the second rotating part 111b. Thus, the first screen 130a and the second screen 130b can also rotate with the long axis L of the limiting shaft 111 as the central axis. The first screen 130a and the second screen 130b are coaxially pivoted to the limiting shaft 111, so that the user can rotate and adjust the position and display surface direction of the first screen 130a and the second screen 130b relative to the base 110, so as to visually view the display surface of the first screen 130a or the second screen 130b. In addition, the first screen 130a and the second screen 130b are connected to the first rotating portion 111a and the second rotating portion 111b of the limiting shaft 111 via the first connecting arm 160a and the second connecting arm 160b, respectively.

[0048] In addition, the limiting shaft 111 further has a core shaft 111c, wherein the core shaft 111c is disposed between the first rotating portion 111a and the second rotating portion 111b, that is, the first rotating portion 111a and the second rotating portion 111b are disposed at opposite ends of the core shaft 111c, the first rotating portion 111a and the second rotating portion 111b can rotate relative to the core shaft 111c, and the core shaft 111c is fixedly connected to other fixed structures of the base 110, such as a housing or other fixed structures. Therefore, when the dual-screen device 100 of the present invention is placed on a plane via the base 110, the first screen 130a and the second screen 130b can rotate relative to the plane via the first rotating portion 111a and the second rotating portion 111b of the limiting shaft 111, while the core shaft 111c of the limiting shaft 111 will not rotate relative to the plane. In addition, the core shaft 111c can provide a torsion force to fix the first rotating part 111a and the second rotating part 111b, so that the first screen 130a and the second screen 130b connected to the first rotating part 111a and the second rotating part 111b will not be pulled by the gravity and rotate when no external force is applied. Specifically, the core shaft 111c may include a torsion spring assembly connecting the first rotating part 111a and the second rotating part 111b, so that the core shaft 111c continuously applies a torsion force to the first rotating part 111a and the second rotating part 111b, thereby allowing the first screen 130a and the second screen 130b to resist the gravity and not rotate accordingly.

[0049] In one or more embodiments of the present invention, the limiting shaft 111 further comprises a first arc-shaped blocking piece 113a and a second arc-shaped blocking piece 113b, and the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b can rotate relative to the limiting shaft 111, wherein the first screen 130a is connected to the first rotating portion 111a via the first arc-shaped blocking piece 113a, and the second screen 130b is connected to the second rotating portion 111b via the second arc-shaped blocking piece 113b. In other words, the first arc-shaped blocking piece 113a is connected between the first rotating portion 111a and the first screen 130a, and the second arc-shaped blocking piece 113b is connected between the second rotating portion 111b and the second screen 130b. Thus, the first arc-shaped blocking piece 113a and the first screen 130a can rotate simultaneously based on the first rotating portion 111a, and the second arc-shaped blocking piece 113b and the second screen 130b can rotate simultaneously based on the second rotating portion 111b. When the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b are mutually limited, the first screen 130a and the second screen 130b are separated by a minimum distance and kept separated without contact. In addition, the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b each have an arc concave surface facing and / or abutting against the arc surface of the limiting shaft 111, so that the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b can rotate relative to the limiting shaft 111.

[0050] In one or more embodiments of the present invention, the first arc-shaped baffle 113a has a first Z-shaped front edge F1, and the second arc-shaped baffle 113b has a second Z-shaped front edge F2, wherein the first Z-shaped front edge F1 at least partially abuts against the second Z-shaped front edge F2. In actual operation, if the first screen 130a and the second screen 130b rotate relative to each other, the first Z-shaped front edge F1 and the second Z-shaped front edge F2 will also be driven to move relative to each other.

[0051] Please refer to Figure 6 and Figure 7 , Figure 6 and Figure 7 According to one or more embodiments of the present invention, Figure 5 Schematic diagram of the assembly of the middle limit shaft 111, the first arc-shaped baffle 113a and the second arc-shaped baffle 113b, wherein the first arc-shaped baffle 113a and the second arc-shaped baffle 113b at least partially abut against each other. Figure 6 In the embodiment, the first Z-shaped front edge F1 and the second Z-shaped front edge F2 partially abut against each other, and the first screen 130a and the second screen 130b connected to the first arc-shaped baffle 113a and the second arc-shaped baffle 113b (please also refer to Figure 1 ) can be pushed to rotate toward each other. Figure 7 In the embodiment, the first Z-shaped front edge F1 and the second Z-shaped front edge F2 completely abut against each other and limit each other, and the first screen 130a and the second screen 130b connected to the first arc-shaped baffle 113a and the second arc-shaped baffle 113b (please also refer to Figure 1 ) will not be able to rotate toward each other because the first Z-shaped front edge F1 and the second Z-shaped front edge F2 resist each other. At this time, the first screen 130a and the second screen 130b are separated by a minimum distance and can only rotate in a direction away from each other. In this way, the first Z-shaped front edge F1 and the second Z-shaped front edge F2 can define the minimum spacing distance between the first screen 130a and the second screen 130b to prevent the first screen 130a and the second screen 130b from colliding with each other when the first screen 130a and the second screen 130b are moved under force.

[0052] Please refer to Figures 5 to 7The first connecting arm 160a includes a first fixing structure 161a, and the second connecting arm 160b includes a second fixing structure 161b. One side of the first arc-shaped baffle 113a (e.g., the outer surface side away from the limiting shaft 111) is connected to the first fixing structure 161a, and the first arc-shaped baffle 113a is connected to the back side of the first screen 130a via the first fixing structure 161a, that is, the first fixing structure 161a is connected between the first arc-shaped baffle 113a and the first screen 130a. One side of the second arc-shaped baffle 113b (for example, the side away from the outer surface of the limiting shaft 111) is connected to the second fixing structure 161b, and the second arc-shaped baffle 113b is connected to the back side of the second screen 130b (which may be the display surface opposite to the second screen 130b) via the second fixing structure 161b, that is, the second fixing structure 161b is connected between the second arc-shaped baffle 113b and the second screen 130b, wherein the first fixing structure 161a and the second fixing structure 161b extend in different directions (for example, in opposite directions) with the limiting shaft 111 as the center, thereby the first screen 130a and the second screen 130b (please also refer to Figure 1 ) face different directions. Figure 6 In the embodiment, the extension direction E1 of the first fixing structure 161a and the extension direction E2 of the second fixing structure 161b are substantially 180 degrees apart, so that the display surfaces of the first screen 130a and the second screen 130b face opposite directions. Figure 7 In the embodiment, the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b are mutually limited. At this time, the first fixed structure 161a and the second fixed structure 161b cannot rotate toward each other, and the extension direction E1 of the first fixed structure 161a and the extension direction E2 of the second fixed structure 161b include a minimum angle (for example, 105 degrees, 105 degrees or more) Figures 2 to 4 The first screen 130a and the second screen 130b connected to the first fixing structure 161a and the second fixing structure 161b (see Figure 1 ) will also be separated by a shortest distance, but the present invention is not limited to this.

[0053] In addition, the first connecting arm 160a further includes an extension member 163, wherein the extension member 163 is disposed between the first arc-shaped baffle 113a and the first screen 130a, for example, two sides (for example, opposite sides) of the extension member 163 are respectively engaged and / or locked with the first arc-shaped baffle 113a and the first screen 130a. In this way, the first arc-shaped baffle 113a, the extension member 163 and the first screen 130a can rotate simultaneously with the first rotating portion 111a, but the present invention is not limited thereto. The length of the extension member 163 affects the minimum interval between the first screen 130a and the second screen 130b, and the longer the length of the extension member 163, the greater the length of the minimum interval. In other embodiments of the present invention, the extension member 163 is disposed between the second arc-shaped baffle 113b and the second screen 130b, for example, the opposite sides of the extension member 163 are respectively engaged and / or locked with the second arc-shaped baffle 113b and the second screen 130b, but the present invention is not limited thereto.

[0054] In summary, the dual-screen device of the present invention has a limiting shaft that can limit the first screen and the second screen, so that no matter how the first screen and the second screen rotate relative to the limiting shaft, the design of the limiting shaft can at least keep the first screen and the second screen separated, thereby preventing the first screen and the second screen from touching each other or colliding with each other due to excessive rotation force, thereby preventing the first screen and the second screen from being damaged.
