## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a server device, in particular, to a server device and a hard disc data storage device replacement mechanism thereof.
2. Description of Related Art
A server device has a wide using range. A place where Internet is necessary for signal data transmission needs the server device as a relay station to transmit data. The server device has a plurality of data storage devices (e.g. hard disk drives) mounted therein for accessing a large number of signal data.
A traditional server device comprises a case, a mother board, a backplane board, a plurality of trays, and a plurality of hard disk drives. The backplane board is disposed inside the case and coupled to the mother board and the hard disk drives with the trays. The tray is inserted inside the case. Each hard disk drive is mounted inside each tray and electrically connected to the backplane board. And the backplane board is electrically connected to the mother board for the server device to access a large number of signal data.
The traditional server device has the following disadvantages. Each tray merely can accommodate one hard disk drive. However, if the amount of the hard disk drive needs to be increased, the tray has to be increased in the same amount. In this case, the height and width of the server device have to be increased to accommodate the increasing structures of the tray. That is, it will occupy more space in the server device and less room for other components. Furthermore, more structure of the trays will increase the total weight and the material cost of the server device.

The circuit board 33 is clipped between the second data storage device 50 and the tray 31. Same as above, the second data storage device 50 is utilized to store the signal data received by the server device 1.
In addition, since the first data storage device 40 is electrically connected to the circuit board 33 via the first connector 321, and the second data storage device 50 is electrically connected to circuit board 33 via the second connector 322, signal data in the first connector 321 and the second connector 322 can be transmitted to the circuit board 33 via the first connector 321 and the second connector 322, respectively, and transmitted to the backplane board 20 via the third connector 34.
Please refer to FIGS. 4 and 5, which are a perspective assembly view and a schematically perspective view according to the present invention, the housing 11 has an opening 112 formed on an upper portion thereof. The opening 112 has two side edges. The side edge has at least one threaded hole 113. The server device further comprises a supporting frame 60, at least an operation system (OS) storage devices 70, a plurality of securing members 81 and a plurality of locking members 82.
The supporting frame 60 has two folding edges 61 extending and bending from two sides thereof. The folding edge 61 has at least one penetrating hole 611 corresponding to the threaded hole 113. The supporting frame 60 corresponds to the opening 112 of the housing 11 and traverses atop the housing 11. The two folding edges 61 are connected to two side edges of the opening 112 of the housing 11. The securing member 81 passes through the penetrating hole 611 and is fixed to the threaded hole 113. Further, the supporting frame 60 has a plurality of fixing holes 62.
The operation system (OS) storage devices 70 is intervally mounted on the supporting frame 60 and electrically connected to the backplane board 20. The OS storage device 70 has a flange 71 formed on a side thereof. The flange 71 has a piercing hole 711 corresponding to the fixing hole 62. The locking member 82 passes through the piercing hole 711 and is fixed to the fixing hole 62. The operation system (OS) storage device 70 is utilized to store the operation system data for the server device 1, such as Linux, DOS, or other computer or server operation systems.
Please refer to FIG. 6, which is a schematic operation view according to the present invention, the server device 1 further comprises two backplane board 20. The two backplane board 20 are mounted inside the housing 11 and located between the mother board and the data storage device replacement mechanism 30. The backplane board 20 are adjacent to each other. The backplane board 20 includes a connection board 91 and a control board 92. The connection board 91 has a plurality of connection ports 911. The third connector 34 is electrically connected to the plurality of connection ports 911. The plurality of connection ports 911 is electrically connected to the backplane board 20. The control board 92 is electrically connected to the connection board 91 and electrically connected to the mother board.
Therefore, the data storage device replacement mechanisms 30 can be inserted inside the housing 11 of the case 10 from two opposite sides of the case 10, the mother board is located above the data storage device replacement mechanisms 30 inserted from one side of the housing, and the first data storage devices 40 and the second storage devices 50 are located on a side of the mother board and electrically connected to the connection port 911 via the third connector 34 of the data storage device replacement mechanism 30, such that signal data in the first data storage device 40 and the second data storage device 50 is processed by the control board 92 and then transmitted to the mother board. On the other hand, the signal data processed by the mother board can be converted by the control board 92 and then transmitted to the backplane board 20 and to the first data storage device 40 and the second data storage device 50, so as to achieve optimum space utilization performance. Accordingly, the connector assembly 32 is disposed inside the accommodation space 311 of the tray 31, and the first connector 321 offsets relative to the second connector 322, such that the circuit board 33 is disposed inside the second arrangement area 3112 of the tray 31 rather than inside the first arrangement area 3111 of the tray 31, so as to decrease occupied area and volume of circuit board 33 and to decrease material cost of the circuit board 33, in order to achieve cost down effect.
Moreover, since the first connector 321 offsets relative to the second connector 322, it can decrease occupied volume of the first connector 321 and the second connector 322 inside the accommodation space 311 of the tray 31. Accordingly, it can decrease occupied volume of the tray 31, so as to decrease occupied space of the server device 1, in order to achieve save space.
Furthermore, the first data storage device 40 and the second data storage device 50 are arranged inside the first arrangement area 3111 and the second arrangement area 3112 of the tray 31, such that the data storage device replacement mechanism 30 can accommodate a plurality of data storage devices simultaneously. Accordingly, the data storage device replacement mechanism 30 can insert the plurality of data storage devices into the case 10. Hence, in the condition of same height and width, the case 10 can accommodate more data storage devices, so as to achieve effective space utilization. In addition, it can increase storage volume of signal data in the server device 1.
Further, the supporting board 35 is disposed inside the first arrangement area 3111 of the tray 31, so as to enhance structural strength of the tray 31 to support the first data storage device 40.
Also, since the tray 31 is inserted inside the housing 11, when the first data storage device 40 or the second data storage device 50 break down, the tray 31 can be pulled out of the housing 11, and a new first data storage device 40 or a new second data storage device 50 is replaced, then the tray 31 is inserted into the housing 11 again, so as to achieve convenient maintenance.
In addition, the supporting frame 60 corresponds to the opening 112 and traverses atop the housing 11, and then the operation data storage device 70 is mounted on the supporting frame 60, such that The operation system (OS) storage device 70 is supported atop the housing 11 by the supporting frame 60. Accordingly, it can achieve more effective space utilization.
In conclusion, the server device and the data storage device replacement mechanism thereof according to the present invention have industrial applicability, novelty and non-obviousness.
