Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The invention relates to a removable hard disk loading device, and more particularly, to a removable hard disk loading device capable of loading a 3.5-inch hard disk and utilizing an accessory to load a 2.5-inch hard disk.  
         [0003]     2. Description of the Prior Art  
         [0004]     Computer systems have become an essential part of people&#39;s life. Nowadays, almost all work is performed utilizing computers. To support this there is a huge variety of storage media available in the market. For example, soft disks or CD disks are firstly utilized for storing data. The disadvantage of these disks is they are limited in capacity and the number of times they can be overwritten. Furthermore, because of the significantly large population of video data or multimedia data, the amount of a file data is larger than the basic capacity of a normal soft disk or a CD disk. Hard disks are still the most widely utilized storage medium due to their characteristics of large capacity and re-writing ability.  
         [0005]     There are two types of hard disks, 3.5-inch hard disks and 2.5-inch hard disks, available on the market. Generally speaking, the 3.5-inch hard disk is installed in a large computer system (such as a personal computer, or computer server), and the 2.5-inch hard disk is installed in a computer system that is more strictly limited in space (for example, a laptop). Regardless of which disk is used, they are almost always installed inside the housing of the computer system. In other words, it is not easy for the user to load or unload the hard disk inside the housing. Furthermore, because the loading/unloading operation is not easy, the users rarely carry the hard disk as a removable storage medium. This may result in the data exchange of the hard disk being reduced.  
         [0006]     To solve this problem, a removable hard disk loading device was developed. The most well known removable hard disk loading device is an HDD tray. The hard disk is no longer placed inside the housing through the above-mentioned complicated operations. Instead, the hard disk can be connected to the computer system (such as the motherboard) in a simple way (for example, the hard disk is plugged into the computer). Therefore, the trouble of connecting the hard disk can be avoided.  
         [0007]     Please refer to  FIG. 1 , which is a diagram of an HDD tray  100  according to the prior art. As shown in  FIG. 1 , the HDD tray  100  comprises a loading space  1   10  for placing the hard disk. That is, the hard disk is loaded inside the loading space  110 . In addition, the HDD tray  100  further comprises a handle  1   20  enabling users to easily pull out/install the whole HDD tray  100 .  
         [0008]     Please refer to  FIG. 2 , which is a diagram of an HDD tray  100  installed inside a computer server  200 . Generally speaking, because the computer server  200  has to provide a lot of services (such as the storage space on the internet), the computer server  200  needs many hard disks. As shown in  FIG. 2 , the computer server  200  can comprise a plurality of plugs for placing a plurality of HDD trays  100 . As mentioned previously, when the HDD tray  100  is placed inside the computer server  200 , only the handle  1   20  is shown outside the computer server  200 . Therefore, the user can pull out the HDD tray  100  by utilizing the handle. On the other hand, when the hard disk is placed in the HDD tray  100 , the connecting port and the handle  120  are respectively located on different sides of the HDD tray  100 . Therefore, the connecting port is placed inside the computer server  200  such that the connecting port can be connected to the computer server through a well-known IDE bus or SATA bus.  
         [0009]     As mentioned previously, both 3.5-inch and 2.5-inch hard disks are available on the market. Most HDD trays  100 , however, are manufactured according to a specific size of a hard disk. That is, a 3.5-inch hard disk has its own corresponding 3.5-inch HDD tray, and a 2.5-inch HDD tray hard disk has its own corresponding 2.5-inch HDD tray. They can only be utilized with the corresponding size disk. From an economic point of view, if the user owns a 2.5-inch hard disk and a 3.5-inch HDD tray, it is not practical for the user to buy a 3.5-inch hard disk or a 2.5-inch HDD tray as well. Furthermore, many of the computer servers  200  only have spaces corresponding to the 3.5-inch hard disk. That is, even if the user has a 2.5-inch hard disk and a 2.5-inch HDD tray, they cannot easily be utilized in the computer server  200 . Furthermore, if the 2.5-inch and 3.5-inch HDD trays are simultaneously loaded in the computer server  200 , the appearance lacks consistence. Therefore, considering the aesthetics, it is not a good choice to simultaneously utilize the 2.5-inch and 3.5-inch HDD trays.  
       SUMMARY OF THE INVENTION  
       [0010]     It is therefore one of the primary objectives of the claimed invention to provide a removable hard disk loading device to solve the above-mentioned problem.  
         [0011]     According to an exemplary embodiment of the claimed invention, a removable hard disk loading device is disclosed. The removable hard disk loading device comprises: a hard disk drive tray (HDD tray) comprising a first loading space for loading a first hard disk of a first size; and an accessory, capable of being placed in the first loading space, comprising a second loading space for loading a second hard disk of a second size.  
         [0012]     The embodiment of the present invention HDD tray comprises a U-shaped accessory. Therefore, the embodiment of the present invention can support hard disks of different sizes. This means the user does not need to buy additional hard disks or HDD trays. Furthermore, because the embodiment of the present invention HDD tray can support hard disks of different sizes (for example, the 3.5-inch hard disk and 2.5-inch hard disk), the computer server does not need to have spaces with different sizes. In other words, the computer server only needs to support the present invention 3.5-inch HDD tray. Therefore, this ensures the consistency of the appearance, and makes the computer server more aesthetically pleasing.

     DETAILED DESCRIPTION  
       [0017]     Please refer to  FIG. 3 , which is a diagram of a removable hard disk loading device  300  according to the embodiment of the present invention. In this embodiment, the removable hard disk loading device  300  comprises a 3.5-inch HDD tray  310 . As mentioned previously, the HDD tray  310  comprises a loading space  320  for placing a 3.5-inch hard disk. Please note that a U-shaped accessory  330  is placed in the loading space  320  of the HDD tray  310 , wherein the U-shaped accessory  330  also comprises a loading space  340  for placing a 2.5-inch hard disk. Similar to the above-mentioned HDD tray  100 , the HDD tray  310  can also comprise a handle  350  for the user to easily pull out/install the whole removable hard disk loading device  300 .  
         [0018]     The 2.5-inch hard disk can be placed in the loading space  340 , and because the size of the U-shaped accessory  330  corresponds to a 3.5-inch space, the U-shaped accessory  330  can be embedded inside the HDD tray  310 , which originally supported the 3.5-inch hard disk. In addition, because the loading space  340  of the U-shaped accessory  330  corresponds to 2.5-inch hard disk, the 2.5-inch hard disk can be placed inside the U-shaped accessory  330 . In other words, the 2.5-inch hard disk can be placed inside the HDD tray  310  through utilizing the U-shaped accessory  330 .  
         [0019]     Please note that the U-shaped accessory  330  is a removable accessory, and therefore if removed, the HDD tray  310  can load the 3.5-inch hard disk. However, when the U-shaped accessory  330  is installed in the HDD tray  310 , the HDD tray  310  can support 2.5-inch hard disks. That is, the removable hard disk loading device  300  can support both 3.5-inch and 2.5-inch hard disks.  
         [0020]     The embodiment of the present invention HDD tray  310  has a similar structure to the prior art HDD tray  100 . For example, the HDD tray  310  only increases a U-shaped accessory  330 . Therefore, the method and structure for installing the removable hard disk loading device  300  are similar to the prior art HDD tray  100 . In other words, when the removable hard disk loading device  300  is installed inside the computer server, only the handle  350  is shown outside such that the user can utilize the handle  350  to pull out the removable hard disk loading device  300 . On the other hand, when the hard disk is placed in the HDD tray  310  (or the U-shaped accessory  330 ), the connecting port and the handle  350  are respectively located on different sides of the HDD tray  310 . Therefore, the connecting port is placed inside the computer server such that the connecting port can be connected to the computer server through a well-known IDE bus or SATA bus. Those skilled in the art will understand corresponding installation methods and the related steps, and detailed illustration is therefore omitted.  
         [0021]     Please note that the material of the present invention U-shaped accessory  330  is not limited. In other words, the U-shaped accessory  330  can be made of plastics, when cost is a factor, or can be made of metal to utilize the heat radiation ability. These embodiments also obey the spirit of the present invention.  
         [0022]     Please note that in the above disclosure, the present invention removable hard disk loading device  300  is utilized in a computer server. In the actual implementation, however, the field that the present invention is utilized in is not limited. In other words, the removable hard disk loading device  300  can be utilized in a variety of computer systems. This also obeys the spirit of the present invention.  
         [0023]     In contrast to the prior art, the HDD tray comprises a U-shaped accessory. Therefore, the embodiment of the present invention can support hard disks of different sizes, negating the need for the user to buy additional hard disks or HDD trays. Furthermore, because the HDD tray can support hard disks of different sizes (for example, the 3.5-inch hard disk and 2.5-inch hard disk), the computer server does not need to have spaces of different sizes. In other words, the computer server only needs to support the present invention 3.5-inch HDD tray. Therefore, this ensures the consistency of the computer&#39;s appearance, and makes the computer server more aesthetically pleasing.  
         [0024]     Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
