Fig. 1 illustrates a 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), respectively, so that the first screen 130a and the second screen 130b display images or are operated by users in different directions, respectively, but the invention is not limited thereto. In addition, the base 110 is further configured to selectively limit 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 a separation therebetween, thereby avoiding damage caused by collision between the first screen 130a and the second screen 130 b. In practical applications, the first screen 130a and the second screen 130b can be rotated relative to the base 110 by being stressed by each other, and different users can adjust the elevation angles of the first screen 130a and the second screen 130b according to the requirements so as to be convenient 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, wherein the back surface of the first screen 130a is rotatably connected to the base 110 via the first connecting arm 160a, and the back surface of the second screen 130b is rotatably connected to the base 110 via the connecting arm 160 b. The mechanism and structure of the base 110 to limit 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 herein to avoid excessively complicated contents of this paragraph.
Fig. 2 to fig. 4 are schematic side views of a dual-screen device 100 according to one or more embodiments of the invention, in fig. 2 to fig. 4, a base 110 is disposed between a first screen 130a and a second screen 130b, and the first screen 130a and the second screen 130b face the base 110 with their display surfaces as front surfaces. In fig. 2 to 4, the first screen 130a and the second screen 130b are respectively located at different elevation positions. In fig. 2, 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. In fig. 3, the display surfaces of the first screen 130a and the second screen 130b are respectively directed to the upper left and the upper right, 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. In fig. 4, the display surface of the first screen 130a faces to the right, and the display surface of the second screen 130b faces to the upper, 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. As can be seen from fig. 2 to fig. 4, the first screen 130a and the second screen 130b can be rotated to different elevation positions respectively, and the first screen 130a and the second screen 130b are separated at each elevation position at intervals, and do not touch each other or collide with each other due to the overlarge rotating 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, and although the components shown in fig. 5 are separated, the components are combined in actual use, and a person having ordinary skill in the art can understand the assembled state of the components according to fig. 5, the description and other drawings. In some embodiments of the present invention, the base 110 includes a limiting shaft 111, where the limiting shaft 111 has a rotatable first rotating portion 111a and a rotatable second rotating portion 111b, and the first rotating portion 111a and the second rotating portion 111b are respectively located at opposite ends on a 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 connected to two ends of the limiting shaft 111 via 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 111b. Therefore, the first screen 130a and the second screen 130b can also rotate around 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 a user can rotate and adjust the positions and the display surface directions of the first screen 130a and the second screen 130b relative to the base 110, so as to be convenient for viewing 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 limiting shaft 111 via the first connecting arm 160a and the second connecting arm 160b, respectively.
In addition, the limiting shaft member 111 further has a spindle 111c, wherein the spindle 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 spindle 111c, the first rotating portion 111a and the second rotating portion 111b can rotate relative to the spindle 111c, and the spindle 111c is fixedly connected to other fixing structures of the base 110, such as a housing or other fixing structures. 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 limiting shaft 111, and the mandrel 111c of the limiting shaft 111 cannot rotate relative to the placed plane. In addition, the mandrel 111c may provide a torsion force to fix the first rotating portion 111a and the second rotating portion 111b, so that the first screen 130a and the second screen 130b connected to the first rotating portion 111a and the second rotating portion 111b are not rotated by the traction of the gravitational force when no external force is applied. Specifically, the interior of the spindle 111c may include a torsion spring assembly connected to the first rotating portion 111a and the second rotating portion 111b, so that the spindle 111c continuously applies torsion to the first rotating portion 111a and the second rotating portion 111b, and the first screen 130a and the second screen 130b resist the gravitational force and do not 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 baffle 113a is connected between the first rotating portion 111a and the first screen 130a, and the second arc-shaped baffle 113b is connected between the second rotating portion 111b and the second screen 130 b. Thereby, the first arc-shaped baffle 113a and the first screen 130a can be rotated based on the first rotating portion 111a at the same time, and the second arc-shaped baffle 113b and the second screen 130b can be rotated based on the second rotating portion 111b at the same time. When the first and second arc-shaped stoppers 113a and 113b are limited to each other, the first and second screens 130a and 130b are spaced apart by a minimum distance and are kept apart from each other without touching. In addition, each of the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b has 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.
In one or more embodiments of the present invention, the first arcuate flap 113a has a first Z-shaped leading edge F1 and the second arcuate flap 113b has a second Z-shaped leading edge F2, wherein the first Z-shaped leading edge F1 at least partially abuts the second Z-shaped leading edge F2. In practice, 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 relative to each other.
Referring to fig. 6 and 7, fig. 6 and 7 are schematic assembly diagrams of the limiting shaft 111, the first arc-shaped baffle 113a and the second arc-shaped baffle 113b in fig. 5 according to one or more embodiments of the invention, wherein the first arc-shaped baffle 113a and the second arc-shaped baffle 113b are at least partially abutted against 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 are completely abutted against each other to limit each other, and the first screen 130a and the second screen 130b (please refer to fig. 1 at the same time) connected to the first arc-shaped baffle 113a and the second arc-shaped baffle 113b cannot rotate towards each other because the first Z-shaped front edge F1 and the second Z-shaped front edge F2 are abutted against each other, and at this time, the first screen 130a and the second screen 130b are separated by a minimum distance and can only rotate towards a direction away from each other. Thus, 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 avoid collision between the first screen 130a and the second screen 130b when being forced to move.
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 161b. One side of the first arc-shaped blocking piece 113a (for example, the side far from the outer surface of the limiting shaft 111) 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 baffle 113b (e.g., the side far 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 surface of the second screen 130b (may be opposite to the display surface of the second screen 130 b) 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 (e.g., opposite directions) with the limiting shaft 111 as a center, so that the display surfaces of the first screen 130a and the second screen 130b (please refer to fig. 1) face in 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 substantially 180 degrees apart, whereby the display surfaces of the first screen 130a and the second screen 130b face opposite directions. In fig. 7, the first arc-shaped blocking piece 113a and the second arc-shaped blocking piece 113b are limited to each other, and 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 are at a minimum angle (for example, 105 degrees or more or the angle θ1, the angle θ2 or the angle θ3 of fig. 2 to 4), so that 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 at a minimum distance.
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 blocking piece 113a and the first screen 130a, for example, two sides (e.g. opposite sides) of the extension member 163 are respectively engaged with and/or locked to the first arc-shaped blocking piece 113a and the first screen 130a. Therefore, the first arc-shaped baffle 113a, the extension member 163 and the first screen 130a can simultaneously rotate along with the first rotating portion 111a, 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 extension member 163 is disposed between the second arc-shaped baffle 113b and the second screen 130b, for example, opposite sides of the extension member 163 are respectively engaged with and/or locked to the second arc-shaped baffle 113b and the second screen 130b, but the present invention is not limited thereto.
In summary, the dual-screen device of the present invention has the limiting shaft member capable of limiting the first screen and the second screen, so that no matter how the first screen and the second screen rotate toward the limiting shaft member, the design of the limiting shaft member can at least keep the first screen and the second screen separated at intervals, thereby avoiding the first screen and the second screen touching each other or striking each other due to overlarge rotating force, and avoiding the first screen and the second screen from being damaged.
While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not limitation. Many modifications may be made to the embodiments of the disclosure recited herein without departing from the spirit and scope of the disclosure. Thus, the breadth and scope of the present invention should not be limited by any of the above-described embodiments.
