In other words, the sliding element 34 is rotated about the shaft 321, and the torque element 322 provides a torque between the sliding element 34 and the torque assembly 32.
Since the width of the blocking element 323 is longer than the diameter of the hole 341, the blocking element 323 can be used to prevent the shaft 321 from separating from the sliding element 34. The width of the blocking element 323 and the diameter of the hole 341 are measured in the movement direction D1.
The wire-trimming rod 35 is disposed on the sliding element 34, and extends along the axis direction D2, which is perpendicular to or substantially perpendicular to the movement direction D1. The wire-trimming rod 35 is located at a side of the sliding track 20. The limitation element 36 is disposed on sliding element 34. As shown in FIG. 5 and FIG. 6, the limitation element 36 can be a ring-like structure, and two ends of the limitation element 36 are respectively fixed on the sliding element 34.
The wheels 37 are rotatably disposed on the sliding element 34, and located in the sliding groove 21. Each of the wheels 37 respectively passes through the holes 342 of the sliding element 34. Since the wheels 37 are arranged in the movement direction D1, and the holes 342 are arranged along the movement direction D1, the extension of the sliding element 34 is maintained in a direction parallel to or substantially parallel to the movement direction D1.
In this embodiment, each of the wheels 37 includes an axis shaft 371, a bearing 372, a main wheel 373, and a side wheel 374. The axis shaft 371 extends along the axis direction D2, and passes through the hole 342 of the sliding element 34. An end of the axis shaft 371, the bearing 372, the main wheel 373, and the side wheel 374 is located in the sliding groove 21. The bearing 372 extends along the axis direction D2, and is disposed on the axis shaft 371.
The main wheel 373 extends along the axis direction D2, and the main wheel 373 is rotatably disposed on the bearing 372. The main wheel 373 is in contact with a side wall of the sliding groove 21, which is perpendicular to or substantially perpendicular to the elongated opening 211. The side wheel 374 pivots on the bearing 372, and the side wheel 374 extends perpendicular to the axis direction D2 and the movement direction D1. The side wheel 374 may be in contact with the side wall of the sliding groove 21, which faces the elongated opening 211. The sliding mechanism 33 of the hinge 30 is smoothly moved in the sliding groove 21 by the main wheel 373 and/or the side wheel 374.
As shown in FIG. 1 and FIG. 5, the portable electronic device 1 is in the input module. The hinge 30 is moved to an end 22 of the sliding track 20 along the movement direction D1 to make the first edge 43 of the host 40 and the hinge 30 close to the first side surface 124 of the display 10. Moreover, the display 10 is inclined relative to the host 40 by rotating the display 10 or the host 40. In some embodiments, the angle between the display 10 and the host 40 is greater than 90 degrees. In the input module, the first edge 43 of the host 40 is located in the first opening 126 and the second opening 127.
As shown in FIG. 4, in this embodiment, the portable electronic device 1 further includes a signal wire 50 electrically connected to the display 10 and the host 40. The signal wire 50 is located in the sliding-track groove 128.
As shown in FIG. 4, the signal wire 50 is located between an outer surface 24 of the sliding track 20 and a top surface 1281 of the sliding-track groove 128. The signal wire 50 is bent between the outer surface 24 and the top surface 1281. The wire-trimming rod 35 is located between two sections of the bended signal wire 50. In some embodiments, an end of the signal wire 50 may be in contact with and fixed on the outer surface 24 of the sliding track 20, which is adjacent to the end 22. The other end of the signal wire 50 is disposed on the limitation element 36 (as shown in FIG. 5), and is fixed on the sliding element 34 via the limitation element 36. Therefore, when the hinge 30 is moved along the movement direction D1, the signal wire 50 is electrically connected to the display 10 and the host 40 well.
FIG. 7 is a perspective view of the portable electronic device 1 during a transforming process in accordance with some embodiments of the disclosure. When the user starts to change the portable electronic device 1 from the input module to the tablet mode or the watching module, the display 10 can be rotated relative to the host 40 first, to make it so the display 10 and the host 40 are located on a plane. Afterward, the host 40 is moved toward the second side surface 125 of the display 10 along the movement direction D1.
FIG. 8A and FIG. 8B is a perspective view of the portable electronic device 1 in the tablet mode in accordance with some embodiments of the disclosure. FIG. 9 is a schematic cross-sectional view of the portable electronic device 1 in the tablet mode in accordance with some embodiments of the disclosure. When the portable electronic device 1 is in the tablet mode, the host 40 is located in the receiving groove 123, and substantially parallel to the display 10. In some embodiments, the host 40 is completely located in the receiving groove 123. In some embodiments, at least 70%, 80% or 90% volume of the host 40 is located in the receiving groove 123.
The first edge 43 of the host 40 is adjacent to the second side surface 125 of the display 10. The second edge 44 of the host 40 is adjacent to the first side surface 124 of the display 10.
Since the input surface 41 of the host 40 faces the display 10, the operation of the portable electronic device 1 will not be interfered with by accidentally touching the input module 45 when the portable electronic device 1 is in the tablet mode.
Moreover, as shown in FIG. 9, the hinge 30 is moved to an end 23 of the sliding track 20. Since the signal wire 50 is fixed on the hinge 30, the signal wire 50 is gradually unfolded to cover the outer surface 24. Moreover, when the hinge 30 is moved to an end 23 of the sliding track 20, the wire-trimming rod 35 provides a pull force to make the signal wire 50 in the sliding-track groove 128 smooth because the signal wire 50 may clad and abut against the wire-trimming rod 35. Therefore, the hinge 30 can be smoothly moved to the other end 22 of the sliding track 20 again.
When the user starts to change the portable electronic device 1 from the tablet mode to the input module, the host 40 can be pulled out from the display 10, and the display 10 is rotated to be inclined related to the host 40. Therefore, the portable electronic device 1 can be easily changed from the tablet mode to the input module.
FIG. 10 is a schematic view of the portable electronic device 1 in the watching module in accordance with some embodiments of the disclosure. The portable electronic device 1 can be easily changed to the watching module by rotating and turning out the host 40 in the tablet mode relative to the display 10 to make an acute angle between the display 10 and the host 40. In the watching module, the display 10 is inclined relative to the host 40, and the input surface 41 of the host 40 faces the display 10. Therefore, the portable electronic device 1 can be stood on a plane (such as a tabletop), and the images or pictures displayed by the display 10 is convenient for watching.
When the user starts to change the portable electronic device 1 from the watching module to the tablet mode, the host 40 can be rotated to make sure that the host 40 is received in the receiving groove 123. Therefore, the portable electronic device 1 is easily changed from the watching module to the tablet mode.
In conclusion, the portable electronic device of the present disclosure utilizes the sliding track and the hinge to ensure the host can be moved or rotated relative to the display. Moreover, the portable electronic device can be changed to various operation modules by adjusting the relative positions and angles between the host and the display.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
