     DETAILED DESCRIPTION 
     Embodiments of the present disclosure will now be described in detail with reference to the drawings. 
     Referring to  FIGS. 1 ,  2 , and  3 , an electronic device  100  according to an exemplary embodiment is illustrated. The electronic device  100  includes a housing  10 , a drawer  20  received in the housing  10 , and a component  30  carried by the drawer  20 . In this embodiment, the component  30  is a hard disk drive (HDD), and the electronic device  100  is a notebook computer. In other embodiments, the component  30  can be a battery, a CD/DVD drive, or other components, and the electronic device  100  can be a desktop computer, a DVD player, or other electronic devices. 
     The component  30  includes an interface portion  31 . The interface portion  31  is used for electrically connecting the component  30  to a circuit board (not shown) of the electronic device  100 . A plurality of limiting holes  33  is defined on opposite sides of the component  30  next to the interface portion  31 . 
     The housing  10  includes a top wall  11 , a bottom wall  13  parallel to the top wall  11 , and a side wall  15  connecting the top wall  11  to the bottom wall  13 . The top wall  11 , the bottom wall  13 , and the side wall  15  cooperate to define a receiving room  17 . The top wall  11  defines a first opening  110 . The side wall  15  defines a second opening  150  communicating with the first opening  110 . The two openings  110  and  150  are used for receiving the drawer  20  to move in or out of the housing  10 . 
     The drawer  20  includes a drawer assembly  21 , a guiding assembly  23 , a drawer cover  25 , and two locking assemblies  27 . 
     The drawer assembly  21  is substantially U-shaped and received in the receiving room  17 . The drawer assembly  21  is used for carrying the component  30 . The drawer assembly  21  is operable to move in and out of the housing  10  via the two openings  110  and  150 . The drawer assembly  21  includes a first flange  211 , a second flange  212  substantially parallel to the first flange  211 , and a third flange  213 . One end of the third flange  213  is connected to the first flange  211 , and the other end of the third flange  213  is connected to the second flange  212 . 
     The three flanges  211 ,  212 , and  213  cooperate to define a receiving space  214 . The receiving space  214  is used for receiving the component  30 . A plurality of limiting poles  2110  is set on inner sides of the first flange  211  and the second flange  212 . The limiting poles  2110  correspond to the limiting holes  33  of the component  30 . By the limiting poles  2110  inserted into the corresponding limiting holes  33 , the drawer assembly  21  transports the component  30 . When the component  30  is carried, the interface portion  31  is away from the third flange  213 , and electrically connects with the circuit board of the electronic device  100 . The third flange  213  is received in the two openings  110  and  150 , and allows convenient manipulation by users for moving the drawer assembly  21  in and out of the receiving room  17 . 
     In other embodiments, the drawer assembly  21  can be other structures as long as the drawer assembly  21  can carry the component  30 . For example, the assembly  21  can further include a bottom plate perpendicularly connected to the three flanges  211 ,  212 , and  213 . The receiving space  214 , used for receiving the component  30 , is defined in the bottom plate, the three flanges  211 ,  212 , and  213 . 
     The guiding assembly  23  is used for supporting the drawer assembly  21  and guiding the drawer assembly  21  to slide in and out of the receiving room  17 . The guiding assembly  23  includes four guiding members  230 . Each guiding member  230  includes a first fixing portion  231 , a second fixing portion  233  substantially parallel to the first fixing portion  231 , and a connecting portion  235  connecting the two fixing portions  231  and  233  and configured to define a guiding groove  237 . 
     The first fixing portion  231  is set on the bottom wall  13  and faces the top wall  11 . The guiding groove  237  is used for receiving one of the two flanges  211  and  212 . As the guiding assembly  23  has four guiding members  230 , four guiding grooves  237  are defined accordingly. Two of the four guiding grooves  237  receive the first flange  211 , and the other two grooves  237  receive the second flange  212 . Thus, the drawer assembly  21  is carried by the guiding assembly  23  and slides in the four grooves  237  and against the connecting portion  235 . In this embodiment, the two fixing portions  231  and  233 , and the connecting portion  235  are cylindrical. The cylindrical connecting portion  235  gives a low friction force to the sliding drawer assembly  21 . In other embodiments, the two fixing portions  231  and  233  can be other shapes, such as plate-shaped. 
     In the embodiment, screws can be engaged with the guiding assembly  23  and the bottom wall  13 , thus, the guiding assembly  23  is fixed on the bottom wall  13 . The guiding assembly  23  can be fixed on the bottom wall  13  by means of any suitable adhesive. 
     In other embodiments, the number of the guiding members  230  can be more than four, and the guiding assembly  23  can be another structure as long as the guiding assembly  23  can guide the drawer assembly  21  to slide in and out of the receiving room  17 . For example, the guiding assembly  23  can have two opposite grooves, one of the two grooves receives the fixing flange  211 , and the other one receives the second flange  212 . 
     Referring to  FIGS. 3 and 4 , to keep the drawer assembly  21  from disengaging out of the receiving room  17 , the drawer cover  25  covers the second opening  150 . Two fixing members  253  perpendicularly extend from opposite ends of the same side of the drawer cover  25 . Two dowels  251  extend from each fixing members  253 . The longitudinal axis of the two dowels  251  are substantially parallel to the plane of the drawer cover  25 . The two dowels  251  are operable to act as shafts of the drawer cover  25 . 
     The two locking assemblies  27  are extending from inner side of the casing  15  and are corresponding to the two dowels  251 . The second opening  150  is defined between the two locking assemblies  27 . The two dowels  251  are rotatablely inserted in the two locking assemblies  27 . Thus, the drawer cover  25  can be rotated out of the second opening  150 . 
     Referring to  FIGS. 3 and 5 , each locking assembly  27  is substantially U-shaped, and includes a first clamping member  271 , a second clamping member  273 , and a connecting member  275  connecting the two clamping members  271  and  273 . One end of the second clamping member  273  is connected to the side wall  15 . The other end of the second clamping member  273  is connected to one end of the connecting member  275 . The other end of the connecting member  275  is connected to the first clamping member  271 , the other end of the first clamping member  271  is free and keeps a distance from the side wall  15  to define a channel  272 . The first clamping member  271 , the second clamping member  273 , and the connecting member  275  define a sliding groove  270 . The sliding groove  270  is used for guiding the corresponding dowel  251  to slide. The two dowels  251  are operable to freely move in and out of the corresponding sliding grooves  270  via the corresponding channels  272 . 
     When the drawer cover  25  is received in the second opening  150 , the two dowels  251  are received in the corresponding channels  272  (as a first state see  FIG. 5 ). When the drawer cover  25  is rotated out of the first opening  110 , the two dowels  251  are moved in the corresponding sliding grooves  270  from the corresponding channels  272  (as a second state see  FIG. 6 ). When the drawer cover  25  is rotated out of the second opening  150 , the drawer assembly  21  is operable to slide in and out of the receiving room  17  by the guiding of the guiding assembly  23  (as a third state see  FIG. 7 ). The component  30  can be removed from the drawer assembly  21 . When the drawer cover  25  is pushed into the receiving room  17  along the sliding grooves  270 , the drawer cover  25  is received in the receiving room  17  (as a fourth state see  FIG. 8 ). Thus, it is easy for users to replace or repair the component  30 . Accordingly, the drawer cover  25  is operable to be pushed into the receiving room  17  by the guiding of the sliding grooves  270  when the component  30  has been replaced or repaired, and placed in the drawer assembly  21 . 
     While various exemplary and preferred embodiments have been described, it is to be understood that the disclosure is not limited thereto. To the contrary, various modifications and similar arrangements (as would be apparent to those skilled in the art) are intended to also be covered. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
