BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to battery cover latching mechanisms and, particularly, to a battery cover latching mechanism used in a portable electronic device. 
         [0003]    2. Description of Related Art 
         [0004]    Batteries are used to provide power to portable electronic devices, e.g., mobile phones. Battery cover latching assemblies are usually provided to secure battery within portable electronic devices. 
         [0005]    A typical battery cover latching assembly for an electronic device usually includes a battery cover and latching means, e.g., a locking pin latching into a locking hole. The battery cover can be detachably mounted to a housing of portable electronic devices using the latching means. 
         [0006]    However, removal of the battery cover may require a strong force, which may damage the locking pin. 
         [0007]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0015]      FIG. 1  shows an exemplary battery cover latching mechanism  100  including a body member  10 , a battery cover  20 , and a button assembly  30 . The battery cover  20  is placed on the body member  10 . The button assembly  30  is rotatably attached to the body member  10 , and is used to releasably lock the battery cover  20  to the body member  10 . 
         [0016]    The body member  10  can be a housing of a portable electronic device. The body member  10  includes a top portion  11 , a bottom portion  12  opposite to the top portion  11 , and two opposite sidewalls  13 . The two sidewalls  13  connect the top portion  11  and the bottom portion  12  to surround a battery receiving space  14 . The top portion  11  defines two first limiting slots  111  communicating with the battery receiving space  14 . The top portion  11  further includes a cavity  15  defined between the two limiting slots  111 , communicating with the battery receiving space  14 . The cavity  15  is defined by a bottom wall  151  and a sidewall  152 . The body member  10  further includes two latching protrusions  16  protruding from the bottom wall  151 . The two latching protrusions  16  are parallel and a latching slot  161  is defined therebetween. In this embodiment, the latching slot  161  includes a pivoting slot  1611  and an inserting slot  1612  communicating with the pivoting slot  1611 . The pivoting slot  1611  is used to rotatably attach the button assembly  30  to the body member  10 . A width of the inserting slot  1612  is smaller than the pivoting slot  1611 . The inserting slot  1612  is a narrow opening, through which the button assembly  30  is inserted into the pivoting slot  1611 . The sidewall  152  defines a concave surface  1521 . The concave surface  1521  facilitates catching the button assembly  30  received in the cavity  15 . The bottom portion  12  of the body member  10  includes two second limiting slots  121  defined therein facing away from the battery receiving space  14 . 
         [0017]    The battery cover  20  is used to enclose the battery receiving space  14 . The battery cover  20  includes a main section  21 , a first end  22 , an opposite second end  23 , and two opposite sidewalls  24 . The main section  21  includes a clamping portion  211 . The main section  21  is partially recessed adjacent to the first end  22  to form the clamping portion  211  for latching the battery cover  20  to the body member  10 . Two tabs  212  are formed on the main section  21  adjacent to the first end  22 , and are used to insert into the first limiting slots  111 . Two limiting blocks  213  are formed on the main section  21  adjacent to the second end  23 , and are used to insert into the second limiting slots  121 . 
         [0018]    Referring to  FIGS. 1 and 2  together, the button assembly  30  includes a connecting member  31  and a button  32 . In this embodiment, the connecting member  31  is a pivoting shaft, and the pivoting shaft  31  is generally a bent bar. The pivoting shaft  31  includes a head portion  311 , a first connecting portion  312 , a mounting portion  313 , a second connecting portion  314 , and a tail portion  315 . The first connecting portion  312  is parallel with the second connecting portion  314 . The mounting portion  313  perpendicularly connects one end of the first connecting portion  312  and one end of the second connecting portion  314  together, forming a U-shaped shelf. The head portion  311  perpendicularly connects to the other end of the first connecting portion  312 . The tail portion  315  perpendicularly connects to the other end of the second connecting portion  314  towards the head portion  311 . The mounting portion  313  is rotatably received in the pivoting slot  1611  through the inserting slot  1612 . The head portion  311  and the tail portion  315  are rotatably mounted to the button  32 , such that the button  32  can rotate about the head portion  311  and the tail portion  315 . Thus, the pivoting shaft  31  can rotate about the mounting portion  313  together with the button  32 . The button  32  includes a latching portion  321  formed at one end thereof, and two ribs  322  formed at an opposite end. Each rib  322  defines a pivoting hole  3221 . The two pivoting ribs  322  are opposite to each other, and the two pivoting holes  3221  are coaxial. The head portion  311  and the tail portion  315  are respectively inserted into a pivoting hole  3221 . The button  32  defines a notch  323 . The notch  323  is arced and cooperates with the concave surface  1521  to facilitate catching the button assembly  30 . 
         [0019]    Referring to  FIG. 3 , to mount the button assembly  30  to the body member  10 , the head portion  311  and the tail portion  315  of the pivoting shaft  31  are respectively inserted into one pivoting hole  3221  of the button  32 . Then the mounting portion  313  of the pivoting shaft  31  is inserted into the pivoting slot  1611 . Thus, the button  32  can rotate about the head portion  311  and the tail portion  315 . The pivoting shaft  31  can rotate about the mounting portion  313 . 
         [0020]    Referring to  FIGS. 4 and 5 , to mount the battery cover  20  to the body member  10 , the battery cover  20  is generally placed over the battery receiving space  14 , with the first end  22  facing the top portion  11  of the body member  10 . The battery cover  20  is pushed towards the top portion  11  until the tabs  212  latches into the first limiting slots  111 , and the limiting blocks  213  latch into the second limiting slots  121 . Then, the button  32  is rotated about the head portion  311  and the tail portion  315 , i.e., a first axis, and the pivoting shaft  31  is rotated about the mounting portion  313 , i.e., a second axis to make the latching portion  321  goes over the clamping portion  211 . At this time, the ribs  322  of the button  32  expose out of the cavity  15 . The ribs  322  are pressed towards the cavity  15 , until the latching portion  321  tightly abuts against the clamping portion  211 , thus the battery cover  20  is tightly locked to the body member  10 . 
         [0021]    To release the battery cover  20  from the body member  10 , the pivoting shaft  31  is rotated about the mounting portion  313  until the latching portion  321  is separated from the clamping portion  211 . Then the battery cover  20  is pushed towards the bottom portion  12  of the body member  10  until the tabs  212  are released from the first limiting slots  111 , and the limiting blocks  213  are released from the second limiting slots  121 . 
         [0022]    The battery cover latching mechanism  100  can tightly lock the battery cover  20  to the body member  10  using the button assembly  30 , and also facilitating opening operation of the battery cover  20  without any breakage. 
         [0023]    It is to be understood, however, that even through numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of sections within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms, in which the appended claims are expressed.
