BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to electronic devices. 
         [0003]    2. Description of Related Art 
         [0004]    Electronic devices, such as DVD players, include a main body, a cover rotatably secured to the main body, and a limiting mechanism for buffering the rotation of the cover. The main body includes a clasp perpendicularly set on the inner surface of the main body. The limiting mechanism is mounted on the inner surface of the main body via the clasp. However, the clasp is deformed to disengage with the limiting mechanism. As a result, the limiting mechanism is easily separated from the main body, and is unable to buffer the rotation of the cover. 
         [0005]    Therefore, there is room for improvement in the art.

The elastic body  31  is received in and held in the second slot  1234 , and the elastic arm  34  is received in the first slot  1231 . In the embodiment, the elastic portion  30  is a torsion spring. 
         [0018]    The limiting mechanism  5  includes a base  51 , a buffering portion  53 , a resisting portion  54 , two locking portions  56 , and two blocking portions  57 . The buffering portion  53 , the blocking portions  56 , and the blocking portions  57  are perpendicular to the base  51  and parallel with each other. The base  51  is substantially rectangular. The base  51  defines a gap  512  and two openings  514 . The gap  512  is set on the center of the base  51 , and is substantially U-shaped. The two openings  514  are set on opposite ends of the base  51 , and are substantially rectangular. 
         [0019]    The buffering portion  53  includes two buffering plates  531 . The two buffering plates  531  perpendicularly extend from opposite edges of the gap  512 . The opposite surfaces of the two buffering plates  531  which face each other are substantially arcuate. The distance between opposite ends of the buffering plates  531  furthest away from the base  51  is greater than the distance between opposite ends of the buffering plates  531  adjacent to the base  51 . 
         [0020]    The resisting portion  54  perpendicular to the buffering portion  53  extends from an edge of the base  51 . A positioning end  541  is perpendicularly arranged at an end of the resisting portion  54  away from the base  51 . The positioning end  541  includes a first arm  5412  and a second arm  5413 . Both of the first arm  5142  and the second arm  5413  are perpendicular to the base  51 . The first arm  5142  is longer than the second arm  5413 . In the embodiment, the resisting portion  54  blocks the limiting mechanism  3  from falling into the through hole  125  during the assembling operation. 
         [0021]    The locking portions  56  extend from an edge of the openings  514  adjacent to the buffering portion  53 . The locking portion  56  is substantially rectangular. 
         [0022]    The blocking portions  57  are perpendicularly arranged at opposite ends of the base  51  and are connected with an edge of the opening  514  away from the locking portion  56 . Each of the blocking portions  57  includes two first plates  571  parallel with each other, a second plate  572 , and an elastic plate  573 . The first plates  571  and the second plate  572  perpendicularly extend from edges of the opening  514  away from the locking portion  56 . The first plates  571  are substantially L-shaped and perpendicularly connect with opposite edges of the locking portion  56 . The second plate  572  is substantially rectangular and perpendicularly connects to the ends of the first plates  571  furthest away from locking portion  56 . The elastic plate  573  is parallel with the base  51  and is arranged between the two first plates  571 . The elastic plate  573  is a predetermined distance from the first plates  571  and perpendicularly connects with second plate  572 . The distance between the elastic plate  573  and the base  51  is less than the distance between the hook  153  and the upper cover  10 , but is larger than the height of the locking portion  56  relative to the base  51 . In the embodiment, the first plates  571  and the second plates  572  enhance the stiffness of the elastic plate  573 , and the distance between the elastic plate  573  and the locking portion  56  is equal to the thickness of the connecting plate  151 . 
         [0023]    The flip cover  2  is substantially rectangular and is capable of being received in the recessed portion  12 . The flip cover  2  includes two rotating members  60 . The rotating members  60  are perpendicularly arranged on the surface of the flip cover  2  facing the main body  1 , and correspond to the through holes  125 . Each of the rotating members  60  includes a securing portion  61 , a bent portion  63 , and a pivot  65 . The securing portion  61  is arranged on an edge of the flip cover  2  where the flip cover  2  rotatably connected with the main body  1 . The securing portion  61  perpendicularly protrudes from an inner surface of the flip cover  2  towards the main body  1 . 
         [0024]    The bent portion  63  bends from an end of the securing portion  61  towards the flip cover  2 . The bent portion  63  protrudes out of an edge of the flip cover  2  rotatably connected with the main body  1 . The end of the bent portion  63  connecting with the securing portion  61  defines a groove  631  (see  FIG. 4 ). The bent portion  63  further includes an operating portion  634 . The operating portion  634  perpendicularly protrudes from the bottom surface of the groove  631 , and engages with the buffering portion  53  for buffering the rotating of the flip cover  2 . The operating portion  634  is substantially wedge shaped. The thickness of an end of the operating portion  634  away from the groove  631  is equal to the distance between opposite ends of the buffering plate  531  adjacent to the base  51 . 
         [0025]    The pivot  65  is set on the end of the bent portion  63  furthest from the securing portion  61 . The pivot  65  is rotatably received in the pivot hole  131 . 
         [0026]    Referring to  FIG. 4 , in assembly, when the clasp  15  is inserted into opening  514  of the limiting mechanism  3 , the elastic plate  573  is deformed by the inserted hook  153  so as to allow the clasp  15  to extend through the opening  514 . When the hook  153  is hooked to an end of the locking portion  56  away from the base  51 , the elastic plate  573  resumes the original position to abut the connecting plate  151 , such that the connecting plate  151  is sandwiched between the locking portion  56  and the blocking portion  57  for preventing the clasp  15  from disengaging with the locking portion  56 . The buffering portion  53  faces the through hole  125 . The pivot  65  is received in the pivot hole  131 . The flip cover  2  is secured to the main body  1  by the pivots  65  being received in the pivot holes  131 , with the operating portion  634  corresponding to the buffering portion  53 . 
         [0027]    After assembly, when electronic device  100  is closed, the flip cover  2  covers the main body  1 . The elastic portion  30  is compressed and the operating portion  634  is away from the buffering portion  53 . When the electronic device  100  is open, the elastic arm  34  is rotated out of the first slot  1231 , and the elastic body  31  is rotated in the second slot  1234 , thus the elastic portion  30  is released for lifting up the flip cover  2  from the main body  1 . At the same time, the operating portion  634  is inserted into the buffering portion  53  for slowing down the rotation of the flip cover  2 . The flip cover  2  is stopped when the operating portion  634  makes contact with the base  51 . 
         [0028]    While various exemplary and preferred embodiments have been described, the disclosure is not limited thereto. On 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.
