Abstract:
A battery holding structure includes a battery receptacle, a receiving chamber, and a locking member. The battery is received in the battery receptacle, and the receiving chamber communicates with the battery receptacle. The locking member is received in the receiving chamber for locking the battery. The battery receptacle includes a base wall, and the battery holding structure also includes a push member. The push member is connected to the base wall elastically, and the push member can create a force to resisting the battery away from the battery receptacle.

BACKGROUND 
     1. Technical Field 
     The present disclosure generally relates to battery holding structures, particularly, to a battery holding structure used in a portable electronic device. 
     2. Description of Related Art 
     Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are widely used. Changeable batteries are installed in most portable electronic devices to supply electric power. When a battery is installed in a portable electronic device, it is generally fixed in place by a battery holding structure, thus the battery and the inner circuits of the portable electronic device are protected. 
     A typical battery holding structure has a battery receiving slot, an elastic member and a coupling member for installation or removal of the battery. One end of the coupling member resists the base surface of the battery. The elastic member can create an elastic force to make the coupling member rotate, thus the end of the coupling member can push the battery out of the battery receiving slot. 
     However, in the process of removing the battery from the battery receiving slot, a large sliding friction is generated between the coupling member and the battery. Over time, the coupling member and the base surface of the battery become abraded due to friction. Therefore, both the battery and the battery holding structure have a relatively short service life. 
     Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
     The present battery holding structure may be used in portable devices, such as mobile phones, personal digital assistants, etc. Referring to  FIG. 1 , an embodiment of the portable electronic device  10  is described and illustrated as a mobile phone. 
     Referring to  FIG. 1  and  FIG. 2 , the portable electronic device  10  includes a battery  20 , a battery receptacle  30 , a receiving chamber  40 , a locking member  50 , and a pushing member  60 . The battery  20  and the pushing member  60  are received in the battery receptacle  30 . The locking member  50  is received in the receiving chamber  40 , and part of the locking member  50  protrudes into the battery receptacle  30 . 
     Referring to  FIG. 2  and  FIG. 3 , the battery  20  includes a first surface  21  and a second surface  23  opposite to the first surface  21 . A first locking slot  211  is defined in the first surface  21  of the battery  20 . A second locking slot  231  and a third locking slot  233  are defined in the second surface  23  of the battery  20 . The second locking slot  231  communicates with the third locking slot  233 . 
     The battery receptacle  30  includes a base wall  31 , a first sidewall  33  and a second sidewall  35  opposite to the first sidewall  33 . The first sidewall  33  and the second sidewall  35  are perpendicular to the base wall  31 . A blind mounting slot  311  is defined in the base wall  31 . A locking portion  331  protrudes from the first sidewall  33  into the battery receptacle  30 , and the locking portion  331  engages with the first locking slot  211  of the battery  20 . 
     The receiving chamber  40  includes a first receiving slot  41  and a second receiving slot  43 . The first receiving slot  41  communicates with the battery receptacle  30  and the second receiving slot  43 . 
     Referring to  FIG. 2  and  FIG. 4 , the locking member  50  includes a main body  51 , a guiding plate  53 , a resisting portion  55 , a switch portion  57 , and a first resilient member  59 . The main body  51  includes a first surface  511 , a second surface  513 , and a third surface  515  perpendicular to each other. A blind mounting hole  5111  is defined from the first surface  511  of the main body  51 . The guiding plate  53  is formed on the first surface  511 . The resisting portion  55  is formed on the second surface  513  and extends into the battery receptacle  30 . The switch portion  57  protrudes from the third surface  515  and extends to the outside of the portable electronic device  10 . One end of the first resilient member  59  is fixed in the blind mounting hole  5111  of the main body  51 , and the other end of the resilient member  59  is fixed in the first receiving slot  41 . In the illustrated embodiment, the first resilient member  59  is a helical, compression spring. 
     The pushing member  60  includes a pushing portion  61  and a second resilient member  63 . The pushing member  60  is partially received in the blind mounting slot  311  of the battery receptacle  30 . In the illustrated embodiment, the second resilient member  63  is a helical, compression spring. Opposite ends of the second resilient member  63  resist the pushing member  61  and a bottom wall of the blind mounting slot  311  correspondingly. When no pressure is applied on the second resilient member  63 , the pushing member  61  partially protrudes out of the blind mounting slot  311  and into the battery receptacle  30 . The pushing portion  61  of the pushing member  60  resists the battery  20  received in the battery receptacle  30  and resisted by the second resilient member  63 , thus the battery  20  can be pushed out of the battery receptacle  30  easily when the locking member  50  is unlocked with the battery  20 . 
     Referring to  FIG. 1  and  FIG. 2 , when installing the battery  20  into the battery receptacle  30 , the first surface  21  of the battery  20  contacts with the first sidewall  33  of the battery receptacle  30 , the locking portion  331  of the first sidewall  33  engages with the first locking slot  211  of the battery  20 . The switch portion  57  of the locking member  50  is actuated by a user, so that the first resilient member  59  becomes compressed. The guiding portion  53  slides from the first receiving slot  41  to the second receiving slot  43 . The resisting portion  55  engages with the second locking slot  231  of the battery  20 . When the battery  20  is pressed, the resisting portion  55  slides in the second locking slot  231 . The battery  20  presses the pushing portion  61  of the pushing member  60  and compresses the second resilient member  63 , so that the pushing member  60  can be completely received in the blind mounting slot  311 . When the switch portion  57  is released, an elastic force created by the first resilient member  59  forces the resisting portion  55  to slide from the second locking slot  231  into the third locking slot  233  of the battery  20  and the battery  20  becomes locked in the battery receptacle  30 . 
     To remove the battery  20  from the battery receptacle  30 , the switch portion  57  of the locking member  50  may be pushed, the resisting portion  55  slides from the third locking slot  233  to the second locking slot  231 . An elastic force created by the second resilient member  63  forces the pushing portion  61  to lift the battery  20 , so that the battery  20  can be removed from the battery receptacle  30 . 
     In the process of pushing the battery  20  out of the battery receptacle  30  by the pushing member  60 , the pushing member  60  and the battery  20  do not slide against each other relatively, therefore, little friction is generated between the pushing member  60  and the battery  20 . Thus, the battery  20  can be protected from abrading. 
     Finally, while various embodiments have been described and illustrated, the disclosure is 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 disclosure as defined by the appended claims.
