BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure generally relates to electronic devices, and particularly to an electronic device with a battery cover fastened to a main body. 
         [0003]    2. Description of Related Art 
         [0004]    Electronic devices, such as computers and mobile phones, are widely used. The electronic devices generally have internal batteries to supply power. The batteries are housed within the electronic devices. 
         [0005]    A typical electronic device includes a main body and a battery cover. The battery cover forms a pair of hooks, and the main body defines a receptacle to receive a battery. Sidewalls of the receptacle define a pair of slots. The hooks of the battery cover are engaged in the slots retaining the battery in the receptacle. However, the hooks are easily abraded, such that the battery cover does not tightly couple on the main body. The battery may, as a result, be unable to make contact with components in the main body effectively, thereby interrupting the power supply. 
         [0006]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0012]    Referring to  FIG. 1  and  FIG. 2 , an exemplary embodiment of an electronic device  50  is shown. In the illustrated embodiment, the electronic device  50  can be a mobile phone, but may alternatively be a PDA (personal digital assistant), notebook, or other device. The electronic device  50  includes a main body  10 , a battery cover  20 , and a latch  30 . A battery (not shown) is received in the main body  10  and retained by the battery cover  20 . 
         [0013]    The main body  10  includes a guide rail  111  formed on opposite sidewalls of the main body  10 , a first surface  112 , and a second surface  113  opposite to the first surface  112 . The main body  10  defines a receptacle  13  in the first surface  112  to receive the battery, and a mounting space  15  in the second surface  113  to receive the latch  30 . The main body  10  defines at least one engaging hole  115  in a sidewall between the sidewalls forming the guide rail  111 . The main body  10  includes a sidewall  131  between the receptacle  13  and the mounting space  15  to separate the receptacle  13  and the mounting space  15 . The sidewall  131  defines an opening  133  to communicate the receptacle  13  with the mounting space  15 . The main body  10  has a bottom wall  151  in the mounting space  15 . The bottom wall  151  forms a holding portion  17  to hold the latch  30 . In the illustrated embodiment, the holding portion  17  includes two symmetrical elongated strips  18  and three protrusions  19 . Each protrusion  19  has a hook (not labeled) at a top end. Alternatively, the strips  18  may be formed integrally as one and two or more of the protrusions  19  may also be formed integrally as one. The strips  18  may be L-shaped or other shape. 
         [0014]    The battery cover  20  forms a plurality of projections  212  on its opposite edges. The battery cover  20  further forms at least one engaging hook  214  and a receiving tab  22  on its other opposite edges. The receiving tab  22  is opposite to the engaging hook  214 . The other two opposite edges are connected to the edges forming the projections  212 . The receiving tab  22  has high strength and is difficult to damage. The receiving tab  22  defines a first cutout  23  and a second cutout  24 . The battery cover  20  forms an operating portion  27  adjacent to the receiving tab  22  to facilitate operation of the battery cover  20  by a finger of a user. In the illustrated embodiment, the operating portion  27  includes a plurality of parallel elongated protrusions. 
         [0015]    The latch  30  includes a first latching portion  31 , a second latching portion  32 , and a connecting portion  33  connecting the first and second latching portions  31 ,  32 . The first and second latching portions  31 ,  32  are bent from opposite ends of the connecting portion  33 , and define a latching opening  34  therebetween. A first bent portion  36  extends inward from an end of the first latching portion  31 , and a second bent portion  37  extends inward from an end of the second latching portion  32 . A first guide portion  38  and a second guide portion  39  extend from ends of the first and second bent portions  36 ,  37  correspondingly. The first and second guide portions  38 ,  39  are bent outwards. As such, the latch  30  is Q-shaped. 
         [0016]    Referring to  FIG. 1  through  FIG. 4 , during assembly of the electronic device  50 , with the latching opening  34  facing the receptacle  13 , the latch  30  is positioned between the elongated strips  18  and the protrusions  19 , thereby held by the holding portion  17 . The battery cover  20  is coupled on the first surface  112  of the main body  10  and slid with the projections  212  of the battery cover  20  on the guide rail  111 . The receiving tab  22  slides through the opening  133  and engages the latch  30 . Once first and second bent portions  36 ,  37  engage the first cutout  23  and the second cutout  24  correspondingly, the battery cover  20  stops sliding and the battery cover  20  is assembled to the main body  10 . During sliding, the receiving tab  22  of the battery cover  20  is guided by the first and second guide portions  38 ,  39  and deforms the latch  30 . The at least one engaging hook  214  is engaged in the at least one engaging hole  115 . 
         [0017]    When a battery is to be installed in or removed from the electronic device  50 , force applied on the battery cover  20 , preferably on the operating portion  27 , impels the receiving tab  22  to deform and disengage from the latch  30 , thus the battery cover  20  is disassembled. The battery is received in the receptacle  13  and battery cover  20  reattached to the main body  10  as described. 
         [0018]    The battery cover  20  is latched on the main body  10  by engagement of the latch  30  and the receiving tab  22 . Therefore, even if the receiving tab  22  is abraded, the latch  30  can still firmly engage the receiving tab. 
         [0019]    Alternatively, the first and second cutouts  23 ,  24  may be replaced by protrusions, and the first and second bent portions  36 ,  37  bent outwards accordingly. The battery cover  20  is not limited to cover a battery. 
         [0020]    Finally, while various embodiments have been described and illustrated, the disclosure is not to be construed as being limited thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
