Fig. 1 is a schematic perspective view of a dual-screen device 100 according to one or more embodiments of the invention. 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 selectively rotate relative to the base 110. Specifically, the first screen 130a and the second screen 130b have display panels (e.g., touch panels), wherein the display surfaces of the first screen 130a and the second screen 130b face different directions (e.g., opposite directions), so that the first screen 130a and the second screen 130b respectively display images for users in different directions or are operated by the users, but the invention is not limited thereto. In addition, the base 110 is further configured to selectively position the first screen 130a and the second screen 130b, so that the first screen 130a and the second screen 130b selectively rotate relative to each other to keep the first screen 130a and the second screen 130b separated from each other at an interval, 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 forced to rotate relative to the base 110, and different users can adjust the elevation angles of the first screen 130a and the second screen 130b according to requirements for visual observation. In addition, the base 110 of the dual-screen device 100 further includes a first connecting arm 160a and a second connecting arm 160b, 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 second connecting arm 160 b. The mechanism and structure for the base 110 to position the first screen 130a and the second screen 130b will be described in detail in the following paragraphs, and only the functions of the base 110 will be described first to avoid the complexity of this paragraph.

Fig. 2 to 4 are schematic side views of the dual-screen device 100 according to one or more embodiments of the invention, in fig. 2 to 4, 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 face away from the base 110 with the display surfaces thereof being front surfaces. In fig. 2 to 4, the first screen 130a and the second screen 130b are located at different elevation angles. In fig. 2, the display surface of the first screen 130a faces upward, and the display surface of the second screen 130b faces to the left, 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 θ 1. In fig. 3, the display surfaces of the first screen 130a and the second screen 130b face to 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 θ 2. In fig. 4, the display surface of the first screen 130a faces to the right side, and the display surface of the second screen 130b faces to the upper side, 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 θ 3. As can be seen from fig. 2 to 4, the first screen 130a and the second screen 130b can rotate to different elevation positions, respectively, and the first screen 130a and the second screen 130b are spaced apart at each elevation position, and will not touch each other or collide each other due to too large rotation force.

Referring to fig. 5, fig. 5 is an exploded view of a portion of the components of the dual-screen device 100 of fig. 1 according to one or more embodiments of the present invention, wherein although the components shown in fig. 5 are separated, the components are combined in actual use, and a person skilled in the art of the present disclosure can understand the assembled state of the components according to fig. 5, the description and other figures. In some embodiments of the present invention, the base 110 includes a limiting shaft 111, the limiting shaft 111 has a rotatable first rotating portion 111a and a rotatable second rotating portion 111b, the first rotating portion 111a and the second rotating portion 111b are respectively located at two opposite ends of the long axis L of the limiting shaft 111, and the first rotating portion 111a and the second rotating portion 111b rotate relative to the long axis L with the long axis L of the limiting shaft 111 as a central axis. Specifically, the first rotating portion 111a and the second rotating portion 111b are respectively connected to two ends of the limiting shaft 111 through bearings (Bearing), but the 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 111 b. Therefore, the first screen 130a and the second screen 130b can also rotate with the long axis L of the limiting shaft 111 as a central axis, and the first screen 130a and the second screen 130b are coaxially pivoted to the limiting shaft 111, so that the user can rotate to adjust the position and the display surface direction of the first screen 130a and the second screen 130b relative to the base 110, so as to visually observe the display surface of the first screen 130a or the second screen 130 b. 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 stopper shaft 111 via the first connecting arm 160a and the second connecting arm 160b, respectively.

In addition, the shaft 111 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 structures for fixing. Therefore, when the dual-screen device 100 of the present invention is placed on a plane through the base 110, the first screen 130a and the second screen 130b can rotate relative to the placed plane through the first rotating portion 111a and the second rotating portion 111b of the position-limiting shaft 111, and the spindle 111c of the position-limiting shaft 111 cannot rotate relative to the placed plane. In addition, the core shaft 111c may 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 do not rotate under the traction of the gravity when no external force is applied. Specifically, the inside of the shaft 111c may include a torsion spring component connecting the first rotating portion 111a and the second rotating portion 111b, so that the shaft 111c continuously applies a torsion force to the first rotating portion 111a and the second rotating portion 111b, and the first screen 130a and the second screen 130b can resist the gravity force and cannot rotate therewith.

In one or more embodiments of the present invention, the limiting shaft 111 further has 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 through the first arc-shaped blocking piece 113a, and the second screen 130b is connected to the second rotating portion 111b through the second arc-shaped blocking piece 113 b. 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 130 b. Therefore, the first arc-shaped baffle 113a and the first screen 130a can rotate simultaneously based on the first rotating portion 111a, and the second arc-shaped baffle 113b and the second screen 130b can rotate simultaneously based on the second rotating portion 111 b. When the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b are limited, the first screen 130a and the second screen 130b are separated by a minimum distance and keep separated without contacting. In addition, the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b have respective arc concave surfaces 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.

In one or more embodiments of the invention, the first curved flap 113a has a first Z-shaped leading edge F1 and the second curved flap 113b has a second Z-shaped leading edge F2, wherein the first Z-shaped leading edge F1 abuts at least partially against the second Z-shaped leading edge F2. In operation, if the first screen 130a and the second screen 130b rotate relatively, the first Z-shaped front edge F1 and the second Z-shaped front edge F2 are also driven to move relatively to each other.

Referring to fig. 6 and 7, fig. 6 and 7 are schematic diagrams illustrating an assembly of the limiting shaft 111, the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b in fig. 5 according to one or more embodiments of the present invention, wherein the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b are at least partially abutted to each other. In fig. 6, 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 (please refer to fig. 1) connected to the first arc-shaped baffle 113a and the second arc-shaped baffle 113b can be pushed to rotate toward each other. In fig. 7, the first Z-shaped front edge F1 and the second Z-shaped front edge F2 completely abut against each other to limit the position of each other, and the first screen 130a and the second screen 130b (please refer to fig. 1) connected to the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b cannot rotate toward each other because the first Z-shaped front edge F1 and the second Z-shaped front edge F2 abut against each other, and at this time, the first screen 130a and the second screen 130b have the minimum distance therebetween and can only rotate away from each other. Thereby, the first Z-shaped front edge F1 and the second Z-shaped front edge F2 can define a minimum separation 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 a force.

Referring to fig. 5 to 7, the first connecting arm 160a includes a first fixing structure 161a, and the second connecting arm 160b includes a second fixing structure 161 b. One side (for example, the outer surface side away from the limiting shaft 111) of the first arc-shaped blocking piece 113a is connected to the first fixing structure 161a, and the first arc-shaped blocking piece 113a is connected to the back surface of the first screen 130a through the first fixing structure 161a, that is, the first fixing structure 161a is connected between the first arc-shaped blocking piece 113a and the first screen 130 a. One side of the second arc-shaped blocking piece 113b (for example, the side of the outer surface far away from the position-limiting shaft 111) is connected to the second fixing structure 161b, and the second arc-shaped blocking piece 113b is connected to the back surface of the second screen 130b (which may be the display surface opposite to the second screen 130 b) through the second fixing structure 161b, that is, the second fixing structure 161b is connected between the second arc-shaped blocking piece 113b and the second screen 130b, wherein the first fixing structure 161a and the second fixing structure 161b extend toward different directions (for example, opposite directions) with the position-limiting shaft 111 as the center, so that the display surfaces of the first screen 130a and the second screen 130b (please refer to fig. 1 at the same time) face toward different directions. In fig. 6, the extending direction E1 of the first fixing structure 161a and the extending direction E2 of the second fixing structure 161b are approximately 180 degrees apart, so that the display surfaces of the first screen 130a and the second screen 130b face opposite directions. In fig. 7, the first arc-shaped stopping piece 113a and the second arc-shaped stopping piece 113b are limited to each other, at this time, the first fixing structure 161a and the second fixing structure 161b cannot rotate toward each other, and the extending direction E1 of the first fixing structure 161a and the extending direction E2 of the second fixing structure 161b form a minimum angle (for example, 105 degrees or more, or the angle θ 1, the angle θ 2 or the angle θ 3 in fig. 2 to fig. 4), so the first screen 130a and the second screen 130b (please refer to fig. 1) connected to the first fixing structure 161a and the second fixing structure 161b are also separated by a minimum distance, but the invention is not limited thereto.

In addition, the first connecting arm 160a further includes an extending member 163, wherein the extending member 163 is disposed between the first arc-shaped blocking piece 113a and the first screen 130a, for example, two sides (for example, two opposite sides) of the extending member 163 are respectively engaged with and/or locked to the first arc-shaped blocking piece 113a and the first screen 130 a. Thereby, the first arc-shaped blocking piece 113a, the extending piece 163 and the first screen 130a can rotate along with the first rotating part 111a at the same time, but the invention is not limited thereto. The length of the extension 163 affects the minimum interval between the first screen 130a and the second screen 130b, and the length of the minimum interval is greater as the length of the extension 163 is longer. In other embodiments of the present invention, the extending element 163 is disposed between the second arc-shaped blocking piece 113b and the second screen 130b, for example, two opposite sides of the extending element 163 are respectively engaged and/or locked with the second arc-shaped blocking piece 113b and the second screen 130b, but the present invention is not limited thereto.
