Abstract:
A hard disk cage for supporting a hard disk includes a frame, and a vibration-proof assembly attached on the peripheral wall of the frame. The vibration-proof assembly absorbs vibration induced by the hard disk and cuts off vibration transmitted by the frame. An electronic device using the hard disk cage is also described.

BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure generally relates to hard disk cages, and particularly to a hard disk cage for use in an electronic device. 
         [0003]    2. Description of Related Art 
         [0004]    Hard drives are widely used in electronic devices (i.e., computers) to drive hard disks. Hard disks are commonly high-capacity designed. The high-capacity hard disks have high running speed when in use. However, the higher speed the hard disk runs, the stronger rotational vibration the hard disk causes, and the high speed hard disk is much more prone to be affected by external vibrations (such as, the vibrations induced by cooling device in server). As a result, the hard disk may be performance degraded, and more seriously, results in an operating failure of the hard disk. 
         [0005]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0010]    According to an exemplary embodiment, a hard disk cage for supporting hard disks is disclosed. The hard disk cage is used in an electronic device, such as a personal computer, a server, for example. 
         [0011]      FIGS. 1 and 2  show a hard disk cage  10  which is for supporting or receiving a hard disk  20 . The hard disk cage  10  includes a frame  11 , a first vibration-proof block  12 , a second vibration-proof block  13 , a first vibration-proof plate  14 , and a second vibration-proof plate  15 . 
         [0012]    The frame  11  is for receiving the hard disk  20 . In the embodiment, the frame  11  includes a first holding board  112 , a first side board  114 , a second holding board  116 , and a second side board  118  which connect together end-to-end. When the hard disk  20  is received in the frame  11 , the hard disk  20  is clamped by the first side board  114 , the second holding board  116 , and the second side board  118  to be stably engaged in the frame  11 . 
         [0013]    The first vibration-proof block  12  is attached (such as adhered) to the first holding board  112  to absorb the external vibration (such as vibrations induced by cooling device in server) transmitted by the first vibration-proof block  12  and absorb the rotational vibration induced by the hard disk  20 . In the embodiment, the first vibration-proof block  12  is attached on the surface of the first holding board  112  towards the second holding board  116 . The hard disk cage  10  may further include a first fastening board  16  which covers the first vibration-proof block  12  and is secured (such as by screws) with the first holding board  112  to enhance the stability of the first vibration-proof block  12  mounting on the first holding board  112 . 
         [0014]      FIG. 3  also shows that the second vibration-proof block  13  is attached (such as adhered) to the second holding board  116  to absorb the external vibration transmitted by the second holding board  116  and absorb the rotational vibration induced by the hard disk  20 . In the embodiment, the second vibration-proof block  13  is attached on the surface of the second holding board  116  towards the first holding board  112 . The hard disk cage  10  may further include a second fastening board  18  which covers the second vibration-proof block  13  and is secured (by such things as screws) with the second holding board  116  to enhance the stability of the second vibration-proof block  13  mounting on the second holding board  116 . 
         [0015]    The first vibration-proof plate  14  is attached (such as adhered) to the first side board  114  to absorb the external vibration transmitted by the first side board  114  and absorb the rotational vibration induced by the hard disk  20 . In the embodiment, the first vibration-proof plate  14  is attached on the surface of the first side board  114  away from the second side board  118 . 
         [0016]    The second vibration-proof plate  15  is attached (such as adhered) to the second side board  118  to absorb the external vibration transmitted by the second side board  118  and absorb the rotational vibration induced by the hard disk  20 . In the embodiment, the second vibration-proof plate  15  is attached on the surface of the second side board  118  away from the first side board  114 . 
         [0017]    The hard disk cage  10  of the exemplary embodiment defines vibration-proof assembly, that is, the first vibration-proof block  12 , the second vibration-proof block  13 , the first vibration-proof plate  14 , and the second vibration-proof plate  15 . When the hard disk  20  runs at a high speed, the vibration-proof assembly can effectively absorb the vibration induced by the hard disk  20 . Furthermore, the vibration-proof assembly can also absorb external vibrations transmitted by the frame  11  of the hard disk cage  10 . As a result, the exemplary hard disk  20  runs stably and has optimal performance. 
         [0018]    It is believed that the exemplary embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its advantages, the examples hereinbefore described merely being preferred or exemplary embodiment of the disclosure.
