Description:
BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The exemplary disclosure generally relates to battery cover mechanisms, and particularly, to a battery cover mechanism used in a portable electronic device. 
         [0003]    2. Description of Related Art 
         [0004]    Batteries are widely used in portable electronic devices, such as personal digital assistants (PDAs), mobile phones, and etc. Conventional batteries are detachably received in the portable electronic device. A battery cover mechanism is designed to secure to a housing of the portable electronic devices to package the batteries, so as to protect the battery and inner circuits of the portable electronic devices from damage of external force. 
         [0005]    A conventional battery cover mechanism generally includes a cover and a housing. The cover tightly engages with the housing to be secured thereon. However, due to the tight engagement of the cover and the housing in many conventional designs, a significant amount of friction exists between the cover and the housing. As a result, the user may need to apply a significant amount of strength to assemble/disassemble the cover to/from the housing. Furthermore, the battery cover needs to be detached from the housing to replace a battery. After replacing the battery, user may forget to reassemble the cover to the housing; as a result the cover may be lost or misplaced. 
         [0006]    Therefore, there is room for improvement within the art.

The operating portion  24  is substantially bar shape, and protrudes from one surface of the main body  21  corresponding to the slot  111  of the top wall  11  of the battery cover  10 . The width of the operating portion  24  is smaller than the width of the slot  111  such that the operating portion  24  can be slidably assembled within the slot  111  of the top wall  11 . The two first locating grooves  26  are recessed from the main body  21  and positioned at two sides of the operating portion  24  corresponding to the two locking blocks  112  of the battery cover  10 . The two second locating grooves  27  are disposed on the main body  21  parallel to the corresponding two first locating grooves  26  respectively. 
         [0018]    Also referring to  FIG. 4  and  FIG. 5 , the body member  30  may be a housing of a portable electronic device. The body member  30  defines a receiving cavity  32  recessed therefrom for receiving the battery cover  10  and the battery  90  therein. The receiving cavity  32  includes several fixing portions  322  protruding from an inner sidewall thereof. Two notches  324  are spaced defined through an opposite inner sidewall of the receiving cavity  32  corresponding to the two latching blocks  22  of the operating piece  20  respectively. 
         [0019]    The connecting assembly  40  is configured to rotatably assemble the battery cover  10  to the body member  30 . The connecting assembly  40  includes a connecting body  42  and a shaft  44  rotatably assembled to the connecting body  42 . The connecting body  42  is a substantially bar shaped board. The connecting body  42  includes a cylinder shaped connecting post  422  longitudinally protruding from a middle portion thereof, corresponding to the gap  15  of the battery cover  10 . A second through hole  4222  is defined through the connecting post  422  axially. Two connecting portions  424  are formed at two ends of the connecting body  42  respectively, extending outward perpendicularly to the connecting post  422 . Each connecting portion  424  defines several fixing holes  426  therethrough corresponding to the fixing portions  322  of the body member  30  respectively. In the exemplary embodiment, the connecting body  42  is fixed to the body member  30  by the welding of the fixing portions  322  into the fixing holes  426  respectively. 
         [0020]    Referring  FIG. 3  through  FIG. 6 , in assembly, the connecting body  42  is assembled to the battery cover  10  with the connecting post  422  being accommodated within the gap  15  of the battery cover  10  and in line with each other. The shaft  44  penetrates through one first through hole  162  of the battery cover  10 , the second through hole  4222  of the connecting body  42  and the other first through hole  162  in turn; such that, the connecting body  42  is rotatably assembled to the battery cover  10 . Then, the connecting body  42  is fixed to the body member  30  by the welding of the fixing portions  322  into the fixing holes  426  respectively; thereby, the battery cover  10  is rotatably assemble to the body member  10  via the connecting assembly  40 . After that, the operating piece  20  is slidably assembled to the battery cover for releasing and locking the battery cover  10  from and to the body member  30 . The two latching blocks  22  penetrate through the corresponding two openings  142  of the battery cover  10  respectively. The operating portion  24  inserts into the corresponding slot  111  and partially exposes from the corresponding slot  111  toward the opposite side thereof. The two locking blocks  112  latch into the corresponding two first locating grooves  26  respectively simultaneously, then, finishing the assembly of the battery cover mechanism  100 . 
         [0021]    When assembling the battery  90  to the battery cover mechanism  100 , one end of the battery  90  is inserted into the receiving space of the battery cover  10  and latched by the two latching portions  134 . The opposite end of the battery  90  is pressed and resists on the corresponding holding boards  113  to secure the battery  90  within the receiving space of the battery cover  10  tightly. After that, the battery cover  10  is rotated toward and accommodated within the receive cavity  32  of the body member  30 . The operating  24  is pushed/moved toward the direction far away from the connecting assembly  40  to make the locking blocks  112  detach from the first locating grooves  26  and latch into the corresponding second locating grooves  27 . The two latching blocks  22  latch into the corresponding two notches  324  of the body member  30  simultaneously, thus, the battery cover  10  with battery  90  attached thereto is secured to the body member  30  tightly. 
         [0022]    When need to replace the battery  90 , the operating  24  is released toward the connecting assembly  40 . The locking blocks  112  is detached from the second locating grooves  27  and latch into the corresponding first locating grooves  26 . Meanwhile, the two latching blocks  22  disengage from the two notches  324 . The battery cover  10  can be rotated to open relative to the body member  30 . Due to a securing of the battery  90  to the battery cover  10 , the battery  90  is exposed to be easily replaced. In addition, due to the battery cover  10  pivotally assembled to the body member  30 , the battery cover  10  cannot be lost.
