## Background
FIELD OF INVENTION
The present invention relates to an extension bracket module, and more particularly to an extension bracket module for mounting an outer switch board of a computer system.
BACKGROUND
A current computer system (or cluster system) comprises many main components and facilities, for example, motherboard, fan, power cord, and power supply, in which many electronic components such as IC component, socket, circuit board, microprocessor card and extension card can further installed on the mother board. However, accompanying the incessant elevation of the functions of the computer system, the facilities and the electronic components are also more and more relatively; they occupy overwhelming space in a housing of the computer system. How to fully utilize the limited space under the condition that the facilities and the electronic components are gradually increased and how to redistribute and plan the space to accept more electronic components in the limited space and giving consideration to the cooling of the electronic component are the current problems that must be faced.
Please refer to FIG. 1. FIG. 1 is a perspective view of a conventional computer system 1 in which many electronic components are disposed. A mother board 12 and a circuit board 13 are installed on the bottom of a housing 11 in a computer system 1 as the figure show, in which the mother board 12 and the circuit board 13 are connected to each other and a plurality of function cards 121 are installed on the upper side of the mother board 12 and a plurality of extension cards are installed on the upper side of the circuit board 13; the mother board 12 and the circuit board 13 are all faced upward to allow the extension card 131 and the function cards 121 to be faced downward to insert onto the motherboard 12 and the circuit board 13 and hence, the motherboard 12 and the circuit board 13 face upward and are connected side to side to each other such that not only more extension cards 131 and function cards 121 are unable to be accepted on the motherboard 12 and the circuit board 13 but also the circuit board 13 and the motherboard 12 also occupy the extra longitudinal or transverse space of the whole computer system 1. Besides, the assembly distributions of the motherboard 12 and the function cards 121 as well as the circuit board 13 and the extension cards 131 on the computer system are also unable to allow the heat generated when the function cards 121 and the extension cards 131 are in operation to be expelled in good measure owing to the limited space of the computer system 1, and when the extension card 121 or an internal electronic component is damaged, the housing 11 of the computer system 1 must be detached to allow the maintenance operation to be processed; this also causes a user to be inconvenient on the assembly. Moreover, using screws one by one to lock the extension cards 131 and the function cards 121 onto the housing 11 after the extension cards 131 and the function cards 121 are inserted in the circuit board 13 also causes the locking time to be wasted.
Thereupon, for designing a special mounting module for allowing more electronic components to be mounted thereon, satisfying cooling requirement of the electronic components and overcoming the deficits of the prior art mentioned above, the present invention is proposed.
SUMMARY
For improving the deficits mentioned above, the present invention provides an extension bracket module, thereby the distribution of the internal space of a computer system can be planned so as to save the space.
Therefore, the present invention provides an extension bracket module used for mounting an outer switch board of a computer system; the extension bracket module is constituted by a top plate and a panel. The top plate is horizontally disposed to allow the outer switch board to be faced downward to dispose in parallel onto the bottom of the top plate. The upper side of the panel is connected to the front edge of the top plate and the panel itself is perpendicular to the top plate.
The outer switch board in the extension bracket module according to the present invention is faced downward to allow the plurality of extension cards to be insert therein; the extension cards are disposed below the outer switch board. Furthermore, an inner switch board is faced upward to allow a plurality of circuit cards to be inserted therein; the circuit cards are then disposed above the inner switch board. Therefore, the extension cards and the circuit cards can be avoid being disposed at the same horizontal surface to cause them to collide together so that a greater deal of extension cards can be installed in the extension bracket module, and can overcome the deficit that only few extension cards can be installed on the circuit plate in the prior art relatively.
The design that the outer switch board of the extension bracket module of the present invention is faced downward can avoid the deficit that the circuit board of the prior art is faced upward to cause the extra space of the computer system in a longitudinal or transverse direction to be occupied unavoidably when the extension cards are assembled. Therefore, the internal space distribution of the computer system can be planned according to the present invention so as to attain to the space saving effect.
The extension bracket module of the present invention can be utilized to enable the internal space of the computer system to be planned and distributed thereby capable of making full use of the internal space to allow a fan corresponding to each electronic component to be added; the fan directly cool the electronic component so as to solve the problem that the space distribution in the prior art is unable to allow the enough cooling fans to be added to cool electronic components directly and effectively. Hence, the heat generated when the electronic component is in operation can be fully expelled to elevate the electronic component cooling efficiency according to the present invention.
When an electronic component in the computer system is to be replaced, only detaching the extension bracket module quickly and directly from the computer system to take out the electronic component is enough; this can avoid the deficit that the minute and complicate procedures of detaching the housing must be first processed and then to replace the electronic component in the prior art and process the assembly and the detaching of the electronic component more conveniently.
The present invention can solve the varieties of deficits that only few extension cards can be assembled, the longitudinal or transverse space of the whole computer system must be extraordinarily added and etc in the prior art so as to allow more extension cards to be assembled, save the space and elevate the electronic component cooling efficiency as well as be convenient for quickly fixing the extension card; the present invention is provided with high industrial applicability.

FIG. 2B is a perspective view of a back surface of an extension bracket module according to the present invention. FIG. 3 is a perspective view of an extension bracket module and a computer system for allowing the extension bracket module to be assembled in according to the present invention. FIG. 4 is a perspective view of a computer system in which an extension bracket module is assembled according to the present invention. An extension bracket module 2 used for mounting an outer switch board 23 of a computer system 3 is installed in an accepting space 33 of the computer system 3. The extension bracket module 2 is constituted by a top plate 21 and a panel 22.
The top plate 21 is levelly disposed to allow the outer switch board 23 to be faced downward to dispose in parallel onto the bottom surface of the top plate 21, and a plurality of slide rails are disposed on two sides of the top plate 21.

Moreover, the front edge of the inner switch board 31 comprises a plurality of connection sockets 312 and the rear edge of the outer switch board 23 then comprises a plurality of connection heads 233 butted on the connection sockets 312. Because the outer switch board 23 is faced downward to allow the plurality of extension cards 232 to be inserted therein and the inner switch board 31 is faced upward to allow the plurality of circuit boards 311 to be inserted therein, the extension cards 232 and the circuit boards 311 can be prevented from colliding with each other on a position of the same level surface. Therefore, a larger amount of extension cards 232 can be assembled in the extension bracket module 2 and the extra longitudinal or transverse space can be relatively decreased so as to save the space.
The extension bracket module 2 of the present invention can further comprise a mounting seat 27 fixed on the panel 22 and used for mounting a driver.
The extension bracket module 2 of the present invention can further comprises a first positioning element 24 fixed on the top plate 21 and used for positioning the extension cards 232, and the first positioning element 24 comprises a propping board 241 and a fixing sheet 242. The propping board 241 is used for propping against the extension cards 232. The fixing sheets 242 are respectively positioned on two sides of the propping board 241; one end of each fixing sheet 242 is connected to one side of the propping board 241 and another end thereof is fixed on the top plate 21. A plurality of notches 2411 used for allowing the extension cards 232 to be inserted therein to fix are further disposed on the propping board 241, and because the first positioning element 24 is directly pressed down to fix the extension cards 232 at one time, the object of quickly fixing the extension cards 232 can be achieved.
The extension bracket module 2 of the present invention can further comprise at least one handle 25 positioned on the top plate 21 and used for assembling or detaching the top plate 21. The computer system 3 comprises at least one hook groove 34 positioned on at least one of two sides of the accepting space 33. The handle 25 comprises a pivot portion 251 and a swing arm 252; the pivot portion 251 is pivotally connected onto the top plate 21 and comprises a hook portion 2511 used for being engaged with the hook groove 34. The swing arm 252 takes the pivot portion 251 as a center to swing to cause the hook portion 2511 to be separated from the hook groove 34 so as to detach the top plate 21, in which the hook portion 2511 is a raised mass and the hook groove 34 is an indented groove.
The extension bracket module 2 of the present invention can further comprise a position limiting groove 2521 and a second positioning element 223; in which the position limiting groove 2521 is positioned on the swing arm 252, and the second positioning element 223 used for limiting the swinging scope of the swing arm is positioned on the top plate 21 and inserted in the positioning limiting groove 2521, in which the position limiting groove 2521 is circularly arched to allow the swing arm 252 to take the pivot portion 251 as a center to do a circular motion.

As it should be, the grasping element 26 is not limited to the one described in the present embodiment, it can also be an article such as retaining block, rib, tenon or any other equivalent structure capable of being used for locking the swing arm 252 on the end face 32.
But, it must be noticed that although a buckling design such as indented groove and raised mass is taken as an example to explain the realization technology of the hook groove 34 and the hook portion 2511 in the description mentioned above. However, it is easy to understand that the buckling of the hook portion 2511 and the hook groove 34 is only one example of the coupling structure, designs such as hook slip and retaining ring, raised mass and indented groove, flange and retaining groove all can achieve the same coupling effect. Therefore, the hook portion 2511 and the hook groove 34 of the present invention are absolutely not merely limited to the raised mass and the indented groove in the aforementioned embodiment.
When the extension bracket module 2 is to be assembled in the computer system 3 as FIG. 3 shows, a user first turns the extension bracket module 2 shown in FIG. 2A upside down to the back thereof in the direction as FIG. 2B shows, and then assembles the extension bracket module 2 along the direction shown by an arrow A to allow the slide rails 211 disposed on the extension bracket module to be slid on and along the chutes 35 in the computer system 3 to cause the extension bracket module 2 to be slid into the accepting space 33 of the computer system 3 and in the meantime, the handle 25 is accepted in the accepting space 33.
