Abstract:
A battery cover latching mechanism is provided. The battery cover latching mechanism includes a body member, a battery cover, and an elastic member. One end of the elastic member resists the body member, the other end of the elastic member resists the battery cover. The battery cover is attached to the body member. The battery is attached to the battery cover. The elastic member provides an elastic force to open the battery cover allowing the battery to be removed from the body member.

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 body member, 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. To replace the battery, the latching means is released, and then the battery cover is separated from the body member. 
         [0006]    However, removal of the battery cover may require a strong force, which is inconvenient for a user to replace the battery. Furthermore, the battery cover may be lost or misplaced. 
         [0007]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0015]    The present battery cover latching mechanism is suitable for portable electronic devices, e.g., mobile phones. 
         [0016]      FIGS. 1 through 3  show an exemplary battery cover latching mechanism  10  used to latch a battery  20  therein (see  FIG. 6 ). The battery cover latching mechanism  10  includes a body member  11 , a battery cover  12 , an elastic member  13 , and a shaft  14 . The battery cover  12  is rotatably attached to the body member  11  by the shaft  14 . The elastic member  13 , positioned between the body member  11  and the battery cover  12 , resists the battery cover  12 . 
         [0017]    The body member  11  can be a housing of a portable electronic device. The body member  11  includes a top portion  111 , a bottom portion  112  opposite to the top portion  111 , and two sidewalls  113 . The top portion  111 , the bottom portion  112  and the sidewalls  113  surround a receiving space  114  for receiving the battery  20  therein. A receiving groove  1121  is defined in the bottom portion  112  of the body member  11 . Two slots  115  are respectively defined in each sidewall  113 . In this embodiment, each slot  115  is “L”-shaped, and includes an inserting slot  1151  and a latching slot  1152  communicating with the inserting slot  1151  (see  FIG. 2 ). Each sidewall  113  is recessed to define the inserting slot  1151  and the latching slot  1153 . The latching slots  1152  are defined in a longitudinal direction. The sidewall  113  includes an interior wall  1154  adjacent to each latching slot  1152 . Each interior wall  1154  defines a notch  1153 . A pivoting hole  116  is defined in the bottom portion  112 , used to rotatably receive the shaft  14 . The pivoting hole  116  partially extends through the receiving groove  1121 . 
         [0018]    The battery cover  12  is mounted to the body member  11 , and cover the receiving space  114 . The battery cover  12  includes a main body  126  and two opposite sidewalls  127 . The main body  126  includes an exterior surface  121  and an interior surface  122  opposite to the exterior surface  121 . A plurality of limiting blocks  1221  protrude from the interior surface  122 . The limiting blocks  1221  and the interior surface  122  cooperatively define a receiving cavity  1222 , used to receive the battery  20  therein. When the battery cover  12  is mounted on the body member  11 , the receiving cavity  1222  is superposed with the receiving space  114 . Two mounting portions  123  are symmetrically formed on one end of the interior surface  122 . Each mounting portion  123  defines a slit  124 . Each slit  124  is a long, narrow cavity, extending longitudinally. A plurality of latching blocks  125  protrude from the two sidewalls  127 , corresponding to the slots  115 . A projection  1251  (see  FIGS. 4 and 5 ) protrudes from each latching block  125 , facing the interior surface  122  and used to latch with one corresponding notch  1153 . 
         [0019]    The elastic member  13  is a torsional spring, and includes two main portions  131 , two fingers  132 , and a connecting portion  133 . Each of the main portions  131  is coil-shaped and defines a channel  1311  axially therein. Each finger  132  is formed at one end of one main portion  131 . The two channels  1311  are co-axial. The connecting portion  133  is substantially V-shaped, and connects the other ends of the main portions  131  together. The fingers  132  and the connecting portion  133  together forms an angle designated by “θ”. When the angle θ between the fingers  132  and the connecting portion  133  is decreased, a torsional force is generated against the deformation. The shaft  14  includes a first end  141  and a second end  142  opposite to the first end  141 . 
         [0020]    Referring to  FIGS. 4 and 6  together, in assembly, the first end of the shaft  14  is inserted into the pivoting hole  116  from one side thereof until the first end  141  is received in the receiving groove  1121 . The elastic member  13  is inserted into the receiving groove  1121 , and the shaft  14  is received in the main portions  131 . Then the shaft  14  is penetrated into the pivoting hole  116  again from the receiving groove  1121  and exposes out of the pivoting hole  116  from an opposite side thereof. Two opposite ends of the shaft  14  are respectively inserted into one slit  124 . The battery cover  12  is rotated about the shaft  14  towards the body member  11  until the latching blocks  125  latch into the inserting slot  1151 . At this time, the fingers  132  of the elastic member  13  resist the receiving groove  1121 , and the two connecting portions  133  resist the interior surface  122  of the battery cover  12 . The battery cover  12  is pushed to move towards the top end  11  of the body member  11  until the latching blocks  125  latch into the latching slot  1152 . At this time, the projections  1251  respectively latch into one notch  1153 , thus the battery cover latching mechanism  10  is assembled. 
         [0021]    To replace the battery  20 , the battery cover  12  is slid to move towards the bottom portion  112  of the body member  11  until the latching blocks  125  are released from the slots  115 . At this time, the battery cover  12  can be carried up from the receiving space  114  by the elastic member  13 . Thus, a user can easily remove the battery  20  out of the receiving cavity  1222 . Furthermore, the battery cover  12  is rotatably linked to the body member  11 , thus decreasing the chances of being lost or misplaced. 
         [0022]    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.
