Description:
BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to an electronic device and, more particularly, to an electronic device with a battery securing mechanism. 
         [0003]    2. Description of the Related Art 
         [0004]    Electronic devices, such as mobile phones, notebook computers, and personal digital assistants, are widely used in recent years. These electronic devices are generally configured to have rechargeable batteries. 
         [0005]    A typical electronic device includes a main body and an elastic member. The main body defines a rectangular space for receiving a battery. The elastic member has two hooks on its two ends. Two openings are defined in opposite sidewalls adjoining the rectangular space. The hooks are inserted into the two openings to engage with inner walls of each opening. 
         [0006]    In use, the battery is placed into the space. One hook of the elastic member is inserted into one opening of the main body. Then, the elastic member is extended over a top of the battery, and the other hook is inserted into the other opening of the main body to engage the inner walls of the opening, thus securing the battery to the space. 
         [0007]    However, the hooks easily detach from the openings, resulting in a poor mechanical reliability. 
         [0008]    Therefore, a new electronic device is desired to overcome the above-described shortcomings.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0021]    Reference will now be made to the drawings to describe embodiments in detail. 
         [0022]    Referring to  FIGS. 1 through 6 , an electronic device  100  includes a main body  9 , a battery  30 , and a fixing assembly  50 . The main body  9  defines a receiving cavity  10  and a receiving groove  40  adjacent to the receiving cavity  10 . The battery  30  is positioned in the receiving cavity  10 . The fixing assembly  50  is partially positioned in the receiving cavity  40  to fix the battery  30  in the receiving cavity  10 . 
         [0023]    The receiving cavity  10  is cooperatively defined by a first side wall  11 , a second side wall  13  parallel to the first sidewall  11 , and a third side wall  15  connecting the first side wall  11  and the second side wall  13 . The first side wall  11  defines a first latching slot  111  and the second side wall  13  defines a second latching slot  131 . A shape of the first latching slot  111  and the second latching slot  131  may have any shape, such as rectangular, trapezoidal, and triangular. In the illustrated embodiment, the first latching slot  111  and the second latching slot  131  are female dovetail grooves. 
         [0024]    A shape of the battery  30  corresponds to the shape of the receiving cavity  10 . The battery  30  includes a first side surface  31 , a second side surface  33  opposite the first side surface  31 , and a third side surface  35  connecting the first side surface  31  and the second side surface  33 . The first side surface  31  forms a first latching protrusion  311  configured to engage with the first latching slot  111  and the second side surface  33  forms a second latching protrusion  331  configured to engage with the second latching slot  131 . In the illustrated embodiment the first latching protrusion  311  and the second latching protrusion  331  are male dovetail grooves. The third side surface  35  is exposed out of the main body  9 . 
         [0025]    The receiving groove  40  is configured to receive the fixing assembly  50 . The receiving groove  40  includes an inner sidewall  41 . The inner sidewall  41  defines an opening  43  and a sliding slot  411  adjacent to the opening  43 . An extending direction of the sliding slot  411  is parallel to a direction of the receiving groove  40 . 
         [0026]    Referring to  FIGS. 4 and 7 , the fixing assembly  50  includes a locking member  51 , an elastic member  53  connected to the locking member  51 , a guiding member  55  passing through the locking member  51 , and a limiting plate  57  connected to the locking member  51 . 
         [0027]    The locking member  51  includes a button  511  and a resisting member  513  extending from an end of the button  511 . The button  511  is exposed out of the main body  9 . The resisting member  513  connects with the button  511  to form an L-shaped configuration. The resisting member  513  is positioned in the receiving groove  40  and the button  511  is exposed out of the main body  9 . 
         [0028]    A first end of the elastic member  53  abuts against the resisting member  513  and a second end of the elastic member  53  abuts against the inner sidewall  41  of the receiving groove  40 . When the button  511  resists the battery  30 , the elastic member  53  is in a free status. The elastic member  53  may be an elastic element such as a helical spring, leaf spring, and a rubber element. In the illustrated embodiment, the elastic member  53  is a leaf spring, thereby increasing a contact area between the elastic member  53 , the resisting member  513 , and the inner sidewall  41  of the receiving groove  40 . 
         [0029]    The guiding member  55  is substantially parallel to the extending direction of the sliding slot  411 . In the illustrated embodiment, the guiding member  55  is cylindrical. Opposite ends of the guiding member  55  are fixed in the receiving groove  40 . The resisting member  513  of the locking member  51  is slidable along the guiding member  55 . 
         [0030]    When the button  511  slides along the receiving groove  40 , the limiting plate  57  slides in the sliding slot  411 . In addition, the receiving groove  40  is hidden from view outside the main body  9  by the limiting plate  57 . The limiting plate  57  also prevents dusts entering the receiving groove  40 . 
         [0031]    Referring to  FIGS. 1 and 8 , the battery  30  is slid in the main body  9 , by pushing the button  511  to slide towards a direction away from the receiving cavity  10 , thereby compressing the elastic member  53 . The first latching protrusion  311  and the second latching protrusion  331  engage in the first latching slot  111  and the second latching slot  131  respectively, thereby confining the battery  30  to slide into the receiving cavity  10 . The first side wall  11  and the second side wall  13  also guide the battery  30  along. While the battery  30  is pushed into the receiving cavity  10 , the button  511  is unable to move toward the receiving cavity  10 . 
         [0032]    When the battery  30  is completely received in the receiving cavity  10 , the button  511  is urged by the elastic member  53  to move towards the receiving cavity  10  along the guiding member  55 . The button  511  resists the third side surface  35  of the battery  30 . The button  511  and the third side wall  15  of the receiving cavity  10  prevent the battery  30  from moving, thereby removably fixing the battery  30  to the receiving cavity  10 . 
         [0033]    To detach the battery  30  from the main body  9 , the button  511  is pulled to move along a direction away from the receiving cavity  10 , so that the third side surface  35  is no longer blocked by the button  511 . The battery  30  may now be removed from the receiving cavity  10  by sliding the battery  30  out along the first and second latching slots  111 ,  131 . 
         [0034]    The battery  30  is held in place by the first and second latching slot  111 ,  131 , and the first and second side walls  11 ,  13  of the receiving cavity  10 , so there is no need for additional fixing structures. Thus, a configuration of the electronic device  100  is simplified. The third side wall  15  of the receiving cavity  10  and the fixing assembly  50  further fixes the battery  30  to the receiving cavity  10 . 
         [0035]    Referring to  FIG. 9 , a second embodiment of an electronic device (not labeled) is similar to the first embodiment of the electronic device  100  of  FIG. 1 , except that the second latching slot  131  may be replaced by a second latching protrusion  231 , and the second latching protrusion  331  of the battery  30  may be replaced by a latching slot  631  of a battery  60 . 
         [0036]    While various embodiments have been described and illustrated, the embodiments are not to be construed as being limited thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the invention as defined by the appended claims.
