Abstract:
An electronic device includes a housing, a chip card received in the housing, and a chip card protecting cover assembly. The chip card protecting cover assembly includes a housing, a first magnet and a second magnet. The magnetic force between the first magnet and the second magnet drives the protecting cover to rotate relative to the housing, thereby covering or exposing the chip card.

BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to chip card protecting cover assemblies, and particularly to a chip card protecting cover assembly for a portable electronic device. 
         [0003]    2. Description of Related Art 
         [0004]    Typical chip card, such as a subscriber identity module (SIM) card or secure digital memory card (SD) card is fixed to a housing of a hand-held device with a card door for preventing the chip card from falling out of the device. However, to open the door, a slot for finger grasping is needed, which affects the appearance of the housing. 
         [0005]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0011]    Referring to  FIGS. 1 and 2 , an exemplary embodiment of an electronic device  100 , such as mobile phone, includes a chip card protecting cover assembly  10 , a housing  20  and a chip card  30 . The chip card  30  is detachably attached within the housing  20 . The cover assembly  10  covers the chip card insertion hole in the housing  20 . The chip card  30  may be a subscriber identity module (SIM) card or a secure digital memory card (SD). 
         [0012]    The cover assembly  10  includes a protecting cover  12 , a first magnet  14  and a second magnet  16 . 
         [0013]    The protecting cover  12  includes a cover body  122 , a joint  124  protruding from one end of the cover body  122 , and a retaining block  126  protruding from a distal end of the joint  124  opposite to the cover body  122 . In other words, the cover body  122  and the retaining block  126  are located at opposite ends of the joint  124 . The joint  124  is rotatably attached to the housing  20  so the protecting cover  12  is rotatably assembled to the housing  20 . The retaining block  126  defines a retaining slot  1262 , in which the first magnet  14  is fixed. 
         [0014]    The first magnet  14  includes a first north pole  142  and a first south pole  144 . The second magnet  16  includes a second north pole  162  and a second south pole  164 . 
         [0015]    The housing  20  includes a main board  22  and a sidewall  24  protruding from main board  22 . The main board  22  includes a receiving plate  222  and a retaining plate  224 . The chip card  30  is received in the receiving plate  222 . The retaining plate  224  is used to fix the second magnet  16 . A limiting block  2242  protrudes from the retaining plate  224 , to limit a rotation maximum of the protecting cover  12  relative to the housing  20 . 
         [0016]    The sidewall  24  includes an outer surface  242  and an inner surface  244  opposite to the outer surface  242 . A receiving groove  2422  is defined in the outer surface  242 , in which the protecting cover  12  is received. An card insertion hole  2442  is defined in the inner surface  244 . The card insertion hole  2442  is opposite to the receiving plate  222  and communicates with the receiving groove  2422 . The chip card  30  is inserted into the receiving plate  222  through the card insertion hole  2442 . 
         [0017]    In this exemplary embodiment, a way of enabling the joint  124  rotating relative to the housing  20  may be as follows: two protrusions  2446  protrude from the inner surface  244  and are located opposite sides of the receiving groove  2422 , each protrusion  2446  defines a rotation hole  2448 ; the joint  124  defines a shaft hole  1242 ; a shaft  40  is inserted in the rotation holes  2448  and the shaft hole  1242  so the joint  124  can rotate relative to the housing  20  about the shaft  40 . 
         [0018]    Referring to  FIG. 3 , in assembly, the first magnet  14  is fixed in the retaining slot  1262 . The second magnet  16  is fixed to the retaining plate  224 . The chip card  30  is inserted in the receiving plate  222  through the card insertion hole  2442 . The protecting cover  12  is received in the receiving groove  2422 . At this time, the first north pole  142  is opposite to the second north pole  162 , the first south pole  144  is opposite to the second south pole  164 ; the cover body  122  covers the card insertion hole  2442 , the joint  124  is located between the protrusions  2446  with the rotation holes  2448  aligned with the shaft hole  1242 . The shaft  40  is inserted into the rotation hole  2448  and the shaft hole  1242  so the joint  124  is rotatably fixed to the housing  20 , to yield an assembled electronic device  100 . Because the first north pole  142  is opposite to the second north pole  162 , a repulsive force is generated between the first north pole  142  and the second north pole  162 , driving the protecting cover  12  rotating in a clockwise A ( FIG. 3 ), which makes the cover body  122  firmly cover the card insertion hole  2442 . 
         [0019]    Referring to  FIG. 4 , to open the protecting cover  12 , the retaining block  126  is pressed to rotate the retaining block  126  entering into the housing  20  under overcoming the repulsive force between the first north pole  142  and the second north pole  162 . As the retaining block  126  rotates, the repulsive force between the first magnet  14  and the second magnet  16  gradually becomes smaller, but an attractive force between the first north and the second magnet  16  gradually becomes larger. Once the attractive force between the first magnet  14  and the second magnet  16  is larger than the repulsive force between the first magnet  14  and the second magnet  16  the protecting cover  12  automatically opens in a counter clockwise B ( FIG. 4 ) under the attractive force between the first magnet  14  and the second magnet  16 , until the retaining block  126  is limited by the limiting block  242 . At this time, the attractive force between the first magnet  14  and the second magnet  16  make the protecting cover  12  have a tendency of continuously rotating in the counter clockwise B, which makes the cover body  122  firmly be located in an opened state to open the card insertion hole  2442 , where the chip card  30  can be exchanged. 
         [0020]    Although numerous characteristics and advantages of the exemplary 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 the matters of shape, size, and arrangement of parts 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.
