BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to electronic devices, and particularly, to an electronic device having a battery. 
         [0003]    2. Description of the Related Art 
         [0004]    An electronic device, such as a wireless keyboard, a wireless touchpad, a remote control, and the like, usually includes a battery to provide electrical power. A typical electronic device includes a main body, a chamber defined in the main body, a battery received in the chamber, and a battery cover sealing the chamber. The chamber defines a latching groove in an inner surface of the chamber. The battery cover includes a latching protrusion locked in the latching groove, such that, the battery cover is engaged into an opening of the chamber to fix the battery in the chamber. 
         [0005]    However, the latching protrusion of the battery cover tends to abrade easily after excessive use, which may cause a slack between the latching protrusion and the latching groove, resulting in a loose battery in the battery holder. 
         [0006]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0012]    Referring to  FIGS. 1 and 2 , a first embodiment of an electronic device  100  includes a main body  10 , an electrode connecting member  20 , two latching members  30 , a battery cover  40 , a resilient member  50 , and a battery  60 . The electronic device  100  may be a wireless keyboard, a wireless touchpad, a remote control, and the like. In the illustrated embodiment, the electronic device  100  is a wireless keyboard. 
         [0013]    The main body  10  defines a columnar chamber  101  to receive the battery  60 . The chamber  101  includes an opening  102 . The main body  10  further defines a ledge  103  along an inner wall of the chamber  101  adjacent to the opening  102 . The ledge  103  blocks the resilient member  50  from sliding into the chamber  101 . The main body  10  further includes two latching portions  104  defined in the inner side surface of the chamber  101  and facing each other. 
         [0014]    The electrode connecting member  20  is fixed to the battery cover  40 , and contacts an electrode of the battery  60  in the chamber  101 . The latching members  30  are fixed to a side surface of the electrode connecting member  20  corresponding to the latching portions  104 . The resilient member  50  is compressed between the battery cover  40  and the electrode connecting member  20  to apply a restoring elastic force to urge the battery cover  40  and the electrode connecting member  20  toward the opening  102 . The latching members  30  are blocked by the latching portions  104 . 
         [0015]    In the illustrated embodiment, each latching portion  104  is a hook-shaped latching depression defined in an inner side surface of the chamber  101 . The latching portion  104  includes a first guide depression  1041 , a second guide depression  1042 , and a third guide depression  1043 . The first guide depression  1041  extends substantially perpendicularly from the ledge  103  downwards along a direction substantially parallel to a center axis of the main body  10 . The second guide depression  1042  extends from a bottom end of the first guide depression  1041  along a circumference substantially perpendicular to the center axis of the main body  10 . The third guide depression  1043  extends upward from an end of the second guide depression  1042  along a direction substantially parallel to the first guide depression  1041 . A length of the third guide depression  1043  is less than that of the first guide depression  1041 . 
         [0016]    In the illustrated embodiment, the electrode connecting member  20  is substantially a columnar structure. The electrode connecting member  20  includes a screw hole  201  in an upper surface of the electrode connecting member  20 , and a screw threading  202  defined in an inner surface of the screw hole  201 . 
         [0017]    In the illustrated embodiment, each of the latching members  30  is a protrusion fixed to an outer side surface of the electrode connecting member  20 . 
         [0018]    In the illustrated embodiment, the battery cover  40  includes a columnar body  401  and a cover plate  402 . The columnar body  401  extends out from a bottom surface of the cover plate  402 . The battery cover  40  further defines a screw threading  403  at an outer surface of the columnar body  401  corresponding to the screw threading  202  of the screw hole  201  of the electrode connecting member  20 . Accordingly, the electrode connecting member  20  may be fixed to the body  401  of the battery cover  40  by screwing the body  401  into the screw hole  201  of the connecting member  20 . The battery cover  40  may further define an elongated mounting depression  4021  in an upper surface of the cover plate  402  that is easily engageable by a screwdriver to assemble or disassemble the battery cover  40  to the main body  10 . 
         [0019]    The resilient member  50  is a columnar spring. Referring to  FIG. 3 , an inner diameter of the resilient member  50  is larger than or equal to a diameter of the columnar body  401  of the battery cover  40 , and less than an outer diameter of the electrode connecting member  20 . 
         [0020]    In use, to assemble the battery cover  40 , the latching member  30 , and the electrode connecting member  20  into the chamber  101  of the main body  10 , the resilient member  50  is first sleeved on a side surface of the body  401  of the battery cover  40 . A part of the body  401  of the battery cover  40  is then screwed into the screw hole  201  of the electrode connecting member  20 . The two latching members  30  are slid along the corresponding first guide depressions  1041  into the chamber  101  until two ends of the resilient member  50  resists the battery cover  40  and the ledge  103 . The battery cover  40  is then pressed and rotated by an external force to slide the latching members  30  along the second guide depressions  1042  to the other end of the second guide depression  1042 . At this time, the resilient member  50  is compressed. Finally, when the external force is withdrawn, the electrode connecting member  20  and the battery cover  40  moves toward the opening  102  of the chamber  101  due to a restoring elastic force from the resilient member  50 . At this time, the latching members  30  slide toward the opening  102  along the third guide depression  1043 , until the latching members  30  are blocked by the corresponding latching portions  104 . 
         [0021]    To disassemble the battery cover  40  from the chamber  101  of the main body  10 , the battery cover  40  is pressed and rotated by an external force, and the latching members  30  slide along the third guide depression  1043  to an end of the second guide depression  1042  away from the third guide depression  1043 . When the external force is withdrawn, the battery cover  40  with the electrode connecting member  20  can be pulled out, and the latching members  30  slide out of the chamber  101  along the first guide depression  1041 . 
         [0022]    In use, the latching members  30  are blocked by the corresponding latching portions  104  due to the restoring elastic force from the compressed resilient member  50 , such that even though the latching members  30  are abraded after excessive working, a slack between the latching members  30  and the latching portions  104  will not exist due to the restoring elastic force. 
         [0023]    It should be pointed out that the ledge  103  can be omitted, if the first guide depression  1041  of each latching portion  104  extends substantially perpendicularly from the end of the chamber  101  adjacent to the opening  102  downwards along a direction substantially parallel to a center axis of the chamber  101 . 
         [0024]    Referring to  FIG. 4 , a second embodiment of an electronic device  200  includes a main body  210 , an electrode connecting member  220 , two latching members  230 , a battery cover  240 , a resilient member  250 , and a battery  260 . The main body  210  defines a columnar chamber  211 . The main body  210  further includes two latching portions  204  defined in an inner side surface of the chamber  101  and facing each other. The electronic device  200  is similar to the electronic device  100  of the first embodiment, except that each latching portion  204  is a protrusion extending out from an inner side surface of the chamber  211 . Each latching member  230  is blocked by the latching portion  204 . In alternative embodiments, the latching portions  204  may be an elongated protrusion or a hook-shaped protrusion. 
         [0025]    It is should be noted that the configurations of the chamber  101 , the body  401  and the cover plate  402  of the battery cover  40 , are not limited to the configurations described above. The chamber  101 , the body  401 , and the cover plate  402  of the battery cover  40  can include any other suitable structures. For example, if the chamber  101  is rectangular, the body  401  of the battery cover  40  is also rectangular. 
         [0026]    It is noted that the scope of the latching members  30 ,  230  or latching portions  104 ,  204  are not limited to the embodiments described above. The numbers of the latching members  30 ,  230  or latching portions  104 ,  204 , are specifically described and illustrated for the purpose of exemplifying various aspects of the present electronic device  100 ,  200 . 
         [0027]    Finally, while the present disclosure has been described with reference to particular embodiments, the description is illustrative of the disclosure and is not to be construed as limiting the disclosure. Therefore, various modifications can be made to the embodiments by those of ordinary skill in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
