Title: Flat electronic device

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to electronic devices, and more particularly to a flat electronic device. 
     2. Description of Related Art 
     For portability, the volume of a flat electronic device is often small, thus inner space for components thereof is small accordingly. However, a battery, which is often built into the flat electronic device, takes up most of the limited real estate. 
     Therefore, there is room for improvement in the art.

     DETAILED DESCRIPTION 
     The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
     Referring to  FIGS. 1-3 , a flat electronic device  99  includes a main body  100 , a support stand  200  for supporting the main body  100 , and a rotation mechanism  300 . The rotation mechanism  300  is used for pivotally connecting the main body  100  and the support stand  200  such that the main body  100  is capable of rotating with respect to the support stand  200 . 
     The main body  100  is substantially rectangular. The main body  100  includes a display screen  110 , a first surface  120 , a second surface  130  opposite to the first surface  120 , a positioning portion  140  disposed on the second surface  130 , and a receiving portion  150  formed on the second surface  130  and partially recessed inward. 
     The display screen  110  is disposed on the first surface  120 . The display screen  110  includes a first edge  112  and a second edge  114  perpendicular to the first edge  112 , and the first edge  112  is longer than the second edge  114 . 
     The positioning portion  140  is in the center of the second surface  130 . The positioning portion  140  includes a receiving space  142  on the second surface  130 . 
     The receiving portion  150  is in the middle of the second surface  130 , and extends from the positioning portion  140 , along the second surface  130 , to the side of the first edge  112 . The receiving portion  150  communicates with the receiving space  142  of the positioning portion  140 . 
     The support stand  200  includes a cylindrical battery  210  for powering the main body  100 , and a connecting portion  220  perpendicularly connected to the middle portion of the battery  210 . The battery  210  is adjacent to the main body  100  at the side of the first edge  112 . The battery  100  is substantially parallel to the first edge  112  of the display screen  110 . 
     The connecting portion  220  is substantially rectangular, and received in the receiving portion  150 . One end of the connecting portion  220  away from the battery  210  is partially cut to form an opening  222 , and two connecting members  224  respectively at opposite sides of the opening  222 . 
     The two connecting members  224  respectively define a shaft hole  2240  communicating with the opening  222 . The connecting portion  220  further defines a through hole  226  between the connecting members  224  and communicating with the opening  222 . The through hole  226  is used for receiving wires electrically connected the battery  210  and the main body  100 . 
     The rotation mechanism  300  includes a circular base portion  310 , a rectangular accommodating portion  320  protruding from the base portion  310 , and two shafts  330  respectively protruding from opposite sides of the accommodating portion  320 . The accommodating portion  320  is received in the opening  222 , and the two shafts  330  are respectively inserted into the two shaft holes  2240 , thus the main body  100  is capable of rotating through a first angle with respect to the support stand  200  in a first direction. The first angle is between 0 and 180 degrees. 
     The base portion  310  is rotatably received in the receiving space  142  of the positioning portion  140  such that the main body  100  is capable of rotating through a second angle with respect to the support stand  200  in a second direction. The second direction is perpendicular to the first direction, and the second angle is between 0 and 360 degrees. 
     The base portion  310  defines an opening  312  communicates with an opening  322  defined in the accommodating portion  320  at the side of the through hole  226 , thus the wires can pass through the connecting portion  220  and the rotation mechanism  300  to electrically connect the main body  100  and battery  210 . 
     Referring to  FIG. 4 , when the main body  100  is rotated through the first angle away from the support stand  200  in the first direction, the battery  210  is maintained in parallel with the first edge  112  of the display screen  110 . The connecting portion  220  is rotated out of the receiving portion  150 . The support stand  200 , the main body  100  at the side of the first edge  112  and a flat surface  400  for supporting the flat electronic device  99  combine to form a triangular structure, thus the flat electronic device  99  can stably be mounted on the flat surface  400 . Meanwhile, the first angle is capable of being adjusted because of different demands by rotating the main body  100  or the support stand  200 . 
     Referring to  FIG. 5 , the main body  100  shown by  FIG. 4  is further rotated through the second angle with respect to the support stand  200  in the second direction. In the embodiment, the second angle is 90 degrees, and the battery  210  is parallel to the second edge  114  of the display screen  110 . The support stand  200 , the main body  100  at the side of the second edge  112  and the flat surface  400  combine to form a triangular structure, thus the flat electronic device  99  can be stably mounted on the flat surface  400 . Meanwhile, the first angle is still capable of being adjusted because of different demands by rotating the main body  100  or the support stand  200 . 
     Furthermore, the battery  210  for powering the main body  100  is built out of the main body  100 , thus inner space of the main body  100  can all be used for other electronic components of the flat electronic device  99 . 
     It is to be understood, even though information and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the present embodiments, the disclosure is illustrative only; and that changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
