In this embodiment, the second fixing member 356 is parallel to the first fixing member 354.
The third fixing member 358 is for connecting the second fixing member 356 to the main body 10. In this embodiment, the third fixing member 358 extends from the second fixing member 356, and each of the second fixing member 356 and the third fixing member 358 defines a plurality of second through holes 3581.
Further referring to FIG. 9, the main body 10 includes the housing 19, a supporting board 13, a key module 15, and an assistant module 16.
The housing 19 includes a first casing 11 and a second casing 17 corresponds with the first casing 11. The first casing 11 clamps the second casing 17 to define the housing 19. The housing 19 is for receiving the supporting board 13, the key module 15, and the assistant module 16.
The supporting board 13 is for enforcing the structure of the main body 10. The supporting board 13 is arranged on the second casing 17, and includes a supporting part 130 and two opposite fixing units 132.
The two fixing units 132 extend from the same side of the supporting part 130. The positions of the two fixing units 132 in the supporting board 13 correspond to the two first connecting units 35 in the frame 30, respectively. Each of the two fixing units 132 includes a first fixing part 1321 and a second fixing part 1323. The second fixing part 1323 extends from the supporting part 130. The first fixing part 1321 extends from the second fixing part 1323 and is perpendicular with the supporting part 130. Each of the first fixing part 1321 and the second fixing part 1323 define a plurality of third through holes 1325. The third through holes 1325 of the first fixing part 1321 corresponds with the second through holes 3581 of the second fixing member 356 to receive bolts (not shown) to fix the first fixing part 1321 to the second fixing member 356. The third through holes 1325 of the second fixing part 1323 corresponds with the second through holes 3581 of the third fixing member 358 to receive bolts (not shown) to fix the second fixing part 1323 to the third fixing member 358.
In other embodiments, the first fixing part 1321 and the second fixing part 1323 can be respectively adhered to the second fixing member 356 and the third fixing member 358 with glue.
The third fixing member 358 and the second fixing part 1323 are used for supporting the connection between the first connecting unit 35 and the supporting board 13. In other embodiments, the third fixing member 358 and the second fixing part 1323 can be removed.
The key board 15 is set on the supporting part 130 of the supporting board 13. The key board 15 is used for generating different key signals. The assistant module 16 is set on the second casing 17 through the supporting board 13. The assistant module 16 includes a power unit 161 and an interface unit 163 parallel with the power unit 161. The power unit 161 is for powering the portable electronic device 100.
The interface unit 163 is for connecting other electronic devices, such as a camera, or a printer. The key module 15 and the assistant module 16 are on opposite sides of the pair of the first connecting units 35. Thus, when the portable electronic device 100 is in the first open state (see FIG. 3), the key module 15 and the assistant module 16 is attached through the opening 33 of the frame 30. In this embodiment, the key board 15 includes a circuit board (not labeled) and a key pad (not labeled) electrically mounded on the circuit board. The power unit 161 and the interface unit 163 are electrically connected to the circuit board.
As discussed above, when the two third fixing members 358 rotate relative to the two first fixing members 354, the frame 30, holding the display 20, is driven to rotate relative to the main body 10 to open the portable electronic device 100. Then the main body 10 is straddled by the frame 30, and is supported at the fixed angle by the frame 30. The first predetermined angle θ1 is defined by the main body 10 and the frame 30 is at a viewing angle for the portable electronic device 100. As the main body 10 is inclined to the supporting plane at the fixed angle, which is supplementary to the first predetermined angle θ1, it is easy for the user to input instructions using the key board 15 of the main body 10, and it is easy to facilitate heat dissipation from the main body 10.
Further referring to FIG. 10, the display 20 includes the display panel 21, a carrier 23, and two opposite second connecting units 25.
The carrier 23 carries the display panel 21. In order to decrease the vibration of the display panel 21, two elastic members 210 are filled between the carrier 23 and one end of the display panel 21. In this embodiment, the two elastic members 20 may be on the same side of the second rim 31b. 
Further referring to FIG. 11, the two second connecting units 25 are set on opposite sides of the carrier 23. The two second connecting units 25 are corresponding to the two blind holes 316 of the first rim 31a and the third rim 31c respectively. In this embodiment, the two second connecting units 25 have the same structure, and the second connecting unit 25 set near the first rim 31a is described in detail below.
The second connecting unit 25 includes a shaft 250 and a connecting member 252. The shaft 250 is hollow for receiving wires, thus, the main body 10 and the display 20 can easily be electrically connected through the hollow frame 30 and the hollow shaft 250. One end of the shaft 250 is rotatably received in the blind hole 316, and the other end of the shaft 250 is connected to the connecting member 252. Thus, the second connecting unit 25 can be rotated with the frame 30. The connecting member 252 defines a plurality of fourth through holes 2521.
The carrier 23 defines two opposite through slots 231 and two opposite recesses 235. The two through slots 231 correspond with the two connecting members 252, and are used for receiving the two connecting members 252 respectively. The carrier 23 includes a plurality of receiving housings 233 set on the carrier 23. The receiving housings 233 correspond with the fourth through holes 2521 to receive bolts (not shown) to fix the connecting member 252 to the carrier 23. Thus, when the two connecting members 252 are rotated relative to the frame 30, the carrier 23 carrying the display panel 21 is driven to be rotated relative to the frame 30 between the second open state and the fourth open state. As the display 20 can be rotated in the opening 33 of the frame 30 180 degrees, allowing different viewing angles to be selected by the user.
The two recesses 235 correspond with the latch member 311 of the second rim 31b for receiving the latch member 311 therein. When the display 20 is received in the frame 30, one of the two recesses 235 receives the latch member 311 to decrease the vibration of the display 20.
When the portable electronic device 100 is in the closed state, the display 20 covers the main body 10 with either the display panel 21 or the carrier 23 facing the housing 19 of the main body 10, and the frame 30 receives the main body 10 and the display 20. When the portable electronic device 100 is in the open state, the main body 10 is straddled by the frame 30, and is supported by the frame 30 to define the first predetermined angle θ1 between the main body 10 and the frame 30.
In this embodiment, the display panel 21 is a touch sensitive panel. Thus, the display 20 allows a user to operate the portable electronic device 100 in the second closed sate with touch inputs on the touch sensitive panel.
As discussed above, the frame 30, holding the display 20, is capable of being rotated relative to the main body 10 in the open state. As the first predetermined angle θ1 defined by the main body 10 and the frame 30 is a constant, the frame 30 with the display 20 is steady relative to the main body 10. When the display 20 rotates relative to the frame 30, the second predetermined angle θ2 is defined by the display 20 and the main body 10 can be adjusted to different viewing angles. Thus, it is a useful utility for the portable electronic device 100 that enables it to be viewed at multiple angles.
In other embodiments, the number of the first connecting units 35 can be one, and the number of the second connecting units 25 can be one.
In other embodiments, the portable electronic device 100 can be a media player, a learning machine, or a mobile phone.
It is to be understood, however, that even though numerous embodiments have been described with reference to particular embodiments, but the present disclosure is not limited to the particular embodiments described and exemplified, and the embodiments are capable of considerable variation and modification without departure from the scope of the appended claims.
