[0004] 2. Description of Related Art

[0005] A portable electronic device is an electronic device which a user can carry around and operate on. The portable electronic device is usually small and light for the user to carry conveniently. The common portable electronic device is, for example, a mobile phone, a multimedia player, a personal digital assistant (PDA), a handheld game console, a handheld global positioning system, and a notebook. The present portable electronic devices mostly apply a folding or a sliding type design, so the size of the portable electronic device may be reduced when the two bodies are stacked and expanded when the two bodies are extended.

[0006] The present application relates to a portable electronic device having a plurality of operation modes.

[0007] The present invention relates to a portable electronic device including a lower body, an upper body, and a moving assembly installed between the upper body and the lower body. The moving assembly includes a lower base fixed to the lower body, a middle base pivoted to the lower base along a first axis, and an upper base pivoted to the middle base along a second axis that is substantially paralleled to the first axis. Here, the upper base is slidably connected to the upper body.

[0008] In light of the foregoing, in the present application, the upper body may be under a close mode, a first open mode, and a second open mode relative to the lower body through the moving assembly.

[0009] In order to make the aforementioned and other features and advantages of the present invention more comprehensible, several embodiments accompanied with figures are described in detail below.

The upper base 220 is then slidably connected to the upper body 120.

[0036] In the present embodiment, the lower base 210 is fixed to the lower body 110. In addition, also in the present embodiment, the upper body 120 has a set of sliding tracks 110a, and the upper base 220 has a set of sliding hooks 220a. Each of the sliding hooks 220a corresponds to the pair of sliding tracks 110a. The upper base 220 is slidably connected to the upper body 120 through the pair of sliding tracks 110a and the pair of sliding hooks 220a.

[0037] In the present embodiment, the portable electronic device 110 further includes a pair of torsion springs 130, as indicated in FIG. 5. The pair of torsion springs 130 is disposed between the upper body 120 and the moving assembly 200. More specifically, the pair of torsion springs 130 is disposed between a lower cover 120b of the upper body 120 and the upper base 220 of the moving assembly 200. With the pair of torsion springs 130, the upper body 120 and the moving assembly 200 directly perform relative semi-automatic sliding, and the lower body 110 and the upper body 120 also indirectly perform relative semi-automatic sliding.

[0038] FIG. 6 and FIG. 7 are perspective views taken at two different viewing angles of the moving assembly in FIG. 2 under the first open mode. Referring to FIG. 2, FIG. 6 and FIG. 7, the upper body 120 is tilted relative to the lower body 110 by rotating the upper body 120 relative to the lower body 110 along the second axis A2 through the moving assembly 200.

FIG. 11 is a side view of the lower body and the upper body in FIG. 5 in the process of changing from the close mode to the first open mode. Referring to FIG. 1 and FIG. 10, through the moving assembly 200 in FIG. 2, the upper body 120 may shift a distance along the first direction D1 relative to the lower body 110, until the keyboard module 122 or a touch panel on the lower body 110 is exposed. Referring to FIG. 10 and FIG. 11, the upper body 120 is tilted relative to the lower body 110 by rotating the upper body 120 relative to the lower body 110 along the second axis A2 through the moving assembly 200.

[0041] FIG. 12A is a top view of the portable electronic device in FIG. 1A under the close mode, and where the upper cover of the upper body is removed. FIG. 12B is a cross-sectional view taken along line 12B-12B in FIG. 12A. Referring to FIG. 5, FIG. 6, and FIG. 12B, in order to prevent the upper body 120 from rotating relative to the lower body 110 in the process of moving the upper body 120 relative to the lower body 110, that is, the middle base 215 will not rotate along the first axis Al relative to the lower base 210, the moving assembly 200 further includes a plurality of lower latches 242 and a plurality of third elastic members 243. Here, the lower latches 242 are assembled with the third elastic members 243, so the lower latches 242 can be slidably connected to the lower body 110 to latch the middle base 215. In the present embodiment, the lower latches 242 respectively latch the two ends of the middle base 215.

[0042] To change the portable electronic device from the close mode in FIG. 1B to the second open mode in FIG. 3, the latching of the middle base 215 by the lower latches 242 has to be first relieved. Thus, referring to FIG. 5, the moving assembly 200 further includes a plurality of driver portions 244. The driver portions 244 are disposed on the lower cover 120b of the upper body 120 to push the lower latches 242 respectively, so that the lower latches 242 are not latched to the middle base 215.

[0043] FIG. 13A is a top view of the portable electronic device in FIG. 12A in the process of changing from the close mode to the second open mode. FIG. 13B is a cross-sectional view taken along line 13B-13B in FIG. 13A. Referring to FIG. 12B and 13B, the latching of the middle base 215 and the lower body 110 by the lower latches 242 is relieved by the driver portions 244 through the movement of the upper body 120 relative to the lower body 110 along a second direction D2.

[0044] FIG. 14A is a top view of the portable electronic device in FIG. 12A in the process of changing from the close mode to the second open mode. FIG. 14B is a cross-sectional view taken along line 14B-14B in FIG. 14A. Referring to FIG. 13B and FIG. 14B, when the lower latches 242 are not latching the middle base 215, the upper body 120, the middle base 215, and the upper base 220 rotate relative to the lower body 110 and the lower base 210, such that the driver portions 244 are no longer in contact with the lower latches 242.

[0045] Referring to FIG. 5 and FIG. 8, the moving assembly 200 may includes a set of first elastic members 252. The first elastic members 252 are disposed between the lower base 210 and the middle base 215 to drive the middle base 215 to rotate along the first axis A1 relative to the lower base 210. Hence, referring to FIG. 13B and FIG. 14B, when the driver portions 244 are no longer in contact with the lower latches 242, the first elastic members 252 drive the middle base 215 with elasticity to rotate the middle base 215 along the first axis A1 relative to the lower base 210.

[0046] Referring to FIG. 5 and FIG. 8, in the process of rotating the middle base 215 and the upper base 220 along the first axis A1 relative to the lower base, the moving assembly 200 further includes a plurality of side latches 262 that are disposed on the upper base 220 to prevent the upper base 220 from rotating along the second axis A2 relative to the middle base 215. In the present embodiment, the side latches 262 are elastically and slidably connected to the upper base 220.

[0047] FIG. 12C is a cross-sectional view taken along line 12C-12C in FIG. 12A. FIG. 13C is a cross-sectional view taken along line 13C-13C in FIG. 13A. Referring to FIG. 12C and FIG. 13C, the movement of the upper body 120 relative to the lower body 110 drives the side latches 262 to latch the middle base 215 and the lower base 220.

[0048] FIG. 14C is a cross-sectional view taken along line 14C-14C in FIG. 14A. Referring to FIG. 13C and FIG. 14C, in the process of rotating the upper body 120, the middle base 215, and the upper base 220 relative to the lower body 110 and the lower base 210, the side latches 262 need to latch the middle base 215 and the upper base 220.

[0049] Referring to FIG. 5 and FIG. 8, to ensure the side latches 262 are latching the middle base 215 and the upper base 220, the moving assembly 200 further includes a plurality of brakes 264 that are disposed on the upper body 120. In the present embodiment, the brakes 264 and the driver portions 244 are respectively formed as a single unit.

[0050] FIG. 12D is a cross-sectional view taken along line 12D-12D in FIG. 12A. FIG. 13D is a cross-sectional view taken along line 12D-12D in FIG. 12A. Referring to FIG. 12D and FIG. 13D, in the present embodiment, the movement of the upper body 120 relative to the lower body 110 causes the brakes 264 to respectively latch a plurality of recesses 220b of the upper base 220. Hence, the relative movement between the upper body 120 and the upper base 220 is limited and the latching of the middle base 215 and the upper base 220 by the side latches 262 is ensured.

[0051] FIG. 14D is a cross-sectional view taken along line 14D-14D in FIG. 14A. Referring to FIG. 13D and FIG. 14D, in the process of rotating the upper body 120, the middle base 215, and the upper base 220 relative to the lower body 110 and the lower base 210, the brakes 264 are still respectively latched to the recesses 220b of the upper base 220.

[0052] In order for the upper body 120 to move to the left side as shown in FIG. 13A. Referring to FIG. 5 and FIG. 12A, the moving assembly 200 further includes a plurality of second elastic members 272 and a position-limiting member 274. Here, the second elastic members 272 and the position-limiting member 274 are disposed within the upper body 120, and the position-limiting member 274 is coupled to the upper body 120 through the second elastic members 272. When the upper body 120 changes to the close mode, the position of the upper base 220 is limited by the position-limiting member 274. Hence, the upper base 220 and the inside wall of the upper body 120 maintain a distance as shown in FIG. 12A.

[0053] Referring to FIG. 12A and FIG. 13A, the position-limiting member 274 can limit the position of the upper base 220 under the close mode. Therefore, the upper body 120 can move to the left side of FIG. 13A and cause the upper base 220 to contact the inside wall of the upper body 120. At the time, the side latches 262 latch the middle base 215 and the upper base 220 as shown in FIG. 13C. Moreover, the driver portions 244 also push the lower latches 242, so that the lower latches 242 are not latched to the middle base 215.

[0054] Referring to FIG. 12B and FIG. 14B, when the middle base 215 rotates close to the lower latches 242, the middle base 215 can push the lower latches 242 through inclined plane motion to recover the latch of the lower latches 242 and the middle base 215.

[0055] In the present embodiment, the first open mode exposes the keyboard module 112, so a user can perform character input or touch-control operation. Furthermore, for the convenience of playing videos or multimedia files, the user will only see the display module 122 without seeing the keyboard module 112 under the second open mode. In short, when the upper body 120 of the portable electronic device 100 moves to the right side or the left side, the upper body 120 will tilt with respect to the lower body 110.

[0056] In light of the foregoing, in the present application, the upper body may be under the close mode, the first open mode, and the second open mode relative to the lower body through the moving assembly. Hence, the present invention may have a plurality of operation modes and correspond to a plurality of software modes.

[0057] Although the present invention has been described with reference to the above embodiments, it will be apparent to one of the ordinary skill in the art that modifications to the described embodiment may be made without departing from the spirit of the invention. Accordingly, the scope of the invention will be defined by the attached claims not by the above detailed descriptions.
