Patent Document

BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to battery cover latching assemblies and, particularly, to a battery cover latching assembly used in a portable electronic device. 
         [0003]    2. Description of Related Art 
         [0004]    Battery cover latching assemblies are usually provided to secure and allow required access to batteries of portable electronic devices. 
         [0005]    A typical battery cover latching assembly for an electronic device usually includes a pair of hooks on one end of a battery cover of the electronic device and a locking pin on the other end of the battery cover. Correspondingly, a pair of grooves is defined in a housing of the electronic device. A locking hole corresponding to the locking pin is also defined in the housing. By attaching the battery cover onto the housing, the hooks can enter into the grooves, and the locking pin is securely latched into the locking hole. Thus, the battery cover is secured to the housing. 
         [0006]    However, to detach the battery cover, an external force is needed due to the tight latching of the locking pin into the locking hole. Thus, the battery cover may be damaged, which makes it inconvenient to replace the locked battery. 
         [0007]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0013]      FIGS. 1 and 2  show an exemplary battery cover latching assembly  100  for portable electronic devices, such as mobile phones, digital cameras and etc. The battery cover latching assembly  100  includes two latching assemblies  10 , a battery cover  20 , and a body member  30 . The latching assemblies  10  are rotatably mounted to the body member  30 , configured for releasably latching the battery cover  20  to the body member  30 . 
         [0014]    Each latching assembly  10  includes a button  12  and an elastic member  14 . The button  12  includes a first surface  121  and a second surface  122  opposite to the first surface  121 . The first surface  121  is for being pressed. A securing portion  123  protrudes from one end of the button  12 . A connecting portion  124  protrudes from an opposite end of the button  12 . The securing portion  123  and the connecting portion  124  may be adjacent to the second surface  122 . A latch block  125  protrudes from one side of the connecting portion  124  facing the first surface  121 . In this embodiment, the latch block  125  is a wedge-shaped block. Referring to  FIGS. 2 and 3  together, the latch block  125  includes a wedge-shaped surface  1254  and a latch slot  1252 . The wedge-shaped surface  1254  faces away from the latch slot  1252 . The latch slot  1252  is defined in a wall of the latch block  125  opposite to the wedge-shaped surface  1254 . The battery cover  20  slides into the latch slot  1252  guided by the wedge-shaped surface  1254 . A first clamp block  126  protrudes from the other side of the connecting portion  124  opposite to the latch block  125 . The first clamp block  126  and the connecting portion  124  define a first clamp space  127  for clamping one end of the elastic member  14 . 
         [0015]    The elastic member  14  is a waved sheet. One end of the elastic member  14  is latched in the first clamp space  127 , the other end of the elastic member  14  is clamped to the body member  30 . The elastic member  14  provides a force to rebound the button  12  to an original state. 
         [0016]    The battery cover  20  defines a cutout  22 , corresponding to the button  12 . The button  12  is received in the cutout  22 . A stopping block  24  protrudes from an inside of the battery cover  20 , adjacent to the cutout  22 . The stopping block  24  corresponds to the latch block  125 . The stopping block  24  is latched in the latch slot  1252 . 
         [0017]    The body member  30  defines a receiving cavity  32  to receive a battery (not shown). The receiving cavity  32  is surrounded by two opposite sidewalls  34 . Referring to  FIGS. 2 and 4  together, each sidewall  34  defines a groove  342 , corresponding to the latching assembly  10 . The groove  342  is surrounded by a first wall  3421 , a second wall  3422 , a third wall  3423 . The second wall  3422  is opposite to the first wall  3421 . The first wall  3421  defines a securing hole  3424  for securing the securing portion  123 . The third wall  3423  defines an channel  3425  aligned with the first clamp block  126 . The clamp block  126  can be moveably received in the channel  3425 . A second clamp block  3426  protrudes from one end of the third wall  3423  adjacent to the first wall  3421  (see  FIG. 4 ). The second clamp block  3426  and the third wall  3423  define a second clamp space  3427 , facing the second wall  3422 . The second clamp space  3427  clamps the other end of the elastic member  14 . 
         [0018]    Referring to  FIG. 4 , during assembly, one end of the elastic member  14  is clamped in the first clamp space  127  of the button  12 . The button  12  and the elastic member  14  are inserted into the groove  342 . At this time, the securing portion  123  is latched in the securing hole  3424 , and the other end of the elastic member  14  is clamped in the second clamp space  3427 . Thus, the latching assembly  10  is stably mounted in the body member  30 . 
         [0019]    To latch the battery cover  20  to the body member  30 , the battery cover  20  is positioned over the battery receiving space  32 . The battery cover  20  is pressed towards the body member  30 . During this stage, each stopping block 24  is slid along a corresponding wedge-shaped surface  1254  to push the latch block  125  inwardly. The button  12  is rotated by the stopping block  24  about the securing portion  123  until the first clamp block  126  and the latch block  125  enter into the body member  30 . At this time, the first clamp block  126  is received in the channel  3425 , and the elastic member  14  accumulates an elastic force. The battery cover  20  is continued to be pressed until the stopping blocks  24  go over the wedge-shaped surface  1254 . Then the battery cover  20  is released, and the button  12  is rebounded by the elastic force to drive the stopping blocks  24  to latch into the latch slots  1252 . 
         [0020]    To release the battery cover  12 , the button  12  is pressed to be rotated about the securing portion  123  until the first clamp block  126  and the latch block  125  enter into the body member  30 . During this process, the first clamp block  126  is received in the channel  3425 , and the elastic member  14  accumulates an elastic force. The button  12  is continued to be pressed until the stopping blocks  24  is completely released from the latch block  125 . Thus, a user can easily detach the battery cover  20  from the body member  30 . 
         [0021]    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.
