## Background
BACKGROUND
1. Technical Field
The exemplary invention relates to portable electronic devices, especially to portable electronic device that can have the position of their display adjusted.
2. Description of Related Art
Portable electronic devices with displays, especially portable Audio/Video products are widely used. Considering consumers' requirements for multiple-angled displays, some portable electronic devices have brackets fixed to them. The portable electronic device can “sit” on the desk by propping up the bracket. Thus, users can have a comfortable view of the display.
However, many existing portable electronic products cannot have the length of their support mechanism adjusted. Therefore, the supporting angle of the portable electronic product cannot be freely adjusted.
Therefore, there is room for improvement within the art.

The rod 56 is extended from the base 522 and located between the cantilevers 524. Each cantilever 524 has a stopping portion 5242 bent outwardly from a distal end thereof.
Referring to FIG. 3, during assembly: first, the triggers 50 are respectively mounted to the body section 20; In this state, the sliders 52 are accommodated in the corresponding passages 242; the latching portions 526 are exposed out of the corresponding passages 242 and extended into the mounting portion 224; the stopping portions 5242 resist against the corresponding first inner walls 2442 in the grooves 244 to stopping the sliders 52 escaped from the body section 20; the first coil springs 58 are compressed between the corresponding bases 522 and the corresponding second inner walls 2444, and the operating portions 54 is exposed out of the corresponding passages 242 to facilitate operating the triggers 50.
Referring to FIG. 2, secondly, the first tilting board 31 is hinged to the body section 20 through the torsion spring hinge 34; the second tilting board 32 is hinged to the first tilting board 31 through the first friction hinge 35, and the retaining board 33 is hinged with the second tilting board 32 through the second friction hinge 36. Thus, the tilting adjuster 30 is assembled yet.
Referring to FIGS. 4-6, thirdly, the rotating adjuster 40 is assembled together like below: the first coil springs 48 are wound to the fixing poles 466 of the corresponding retractable members 46; the retractable members 46 are then inserted into the corresponding holes 4442 of the rotating member 44, at this time, the first coil springs 48 are compressed between the corresponding resisting blocks 4424 and the corresponding retractable members 46, the limiting portions 4642 are resisted against the inner wall of the rotating member 44 under the resilient force of the corresponding compressed first coil springs 48, to prevent the retractable members 46 from separating from the rotating member 44. After that, the rotating member 44 is aligned with the opening 422 of the mounting plate 42 and is pushed toward the mounting plate 42 until the peripheral wall 444 of the rotating member 44 is accommodated in the opening 422. At this stage, the flange 446 of the rotating member 44 resists against the inner wall of the mounting plate 42 to prevent the rotating member 44 from separating from the mounting plate 42; the wedged ends 462 of the retractable members 46 are accommodated in notches 424 so that the rotating member 44 is steadily retained in the opening 422 of the mounting plate 42.
Then, referring to FIG. 2, the rotating adjuster 40 is mounted to cover section 10 and the bottom wall 442 of the rotating member 44 is bolted with the retaining board 33 by one or more nuts (not shown) to assemble the rotating adjuster 40 and the tilting adjuster 30 together. Finally, the cover section 10 is pressed toward the body section 20, the cover section 10 is rotated about the second friction hinge 36 relative to the second tilting board 32 until the cover section is parallel to the body section 20, the second tilting board 32 is rotated about the first friction hinge 35 relative to the first tilting board 31 until the second tilting board 32 is accommodated in the receiving slot 312, and the first tilting board 31 is rotated about the torsion spring hinge 34 relative to the body section 20 until the first tilting board 31 is accommodated in the mounting portion 224 and the latching portions 526 of the triggers 50 are latched within the latching slots 314 of the first tilting board 31, so that the portable electronic device is assembled like showing of the FIG. 1.
In use, referring to FIGS. 1-3, the operating portions 54 are pulled outwardly from the mounting portion 224 of the body section 20 until the latching portions 526 of the triggers 50 are disengaged from the latching slots 314 of the first tilting board 31. At this time, the second coil springs 58 are continuously compressed by the corresponding sliders 52 to accumulate resilient force. Then, the first tilting board 31 is ejected out of the mounting portion 224 through the torsion spring hinge 34. After then, a user can adjust the first friction hinge 35 and the second friction hinge 36 to adjust the angle of the cover section 10 relative to the body section 20 until getting a comfortable viewing angle, such as shown in FIG. 7. Additionally, the latching portions 526 are pushed into the mounting portion 224 under the resilient force of the corresponding second coil springs 58.
Referring to FIGS. 2 and 7, when a user want the display 122 crossing with the body section 20, the cover section 10 can be rotated about the rotating member 44 of the rotating adjuster 40, and the detail is: rotating the cover section 10 about the rotating member 44, the wedged ends 462 of the retractable members 46 are slid along the arcuate surfaces 4244 in the notches 424 and the first coil springs 48 are continuously compressed, until the retractable members 46 are aligned with the other notches 424. At this time, the first coil springs 48 are stretched to push the retractable members 46 into the other notches 424, thus the portable electronic device is steadily positioned in a status of the cover section 10 crossing with the body section 20.
It is to be understood, that the planar surfaces 4242 in the notches 424 of FIG. 4 can be substituted to other shape, for example: an arcuate surface 4244; correspondingly, so that the cover section 10 can be clockwise/counterclockwise rotated relative to the body section 20.
It is to be understood that the second tilting board 32 may be directly hinged to the rotating adjuster 40, and the retaining board 33 is omitted.
It is to be understood that the mount of the notches 424 may be changed according to the actual need, for instance: the mount of the notches 424 may be three or four couples. Moreover, the mount of the notches 424 may be only two and the rotating adjuster 40 has only one retractable member 46; at this case, the retractable member 46 is releasably accommodated in the notches 424 in turn, for steadily retaining the cover section 10 in a certain position.
It is to be understood, however, that even through numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
