(b) Description of the Prior Art
When assembling a host computer, an installer first fixedly installs a motherboard within a case of host computer, then related interface cards are inserted according to the requirements of user specifications, and after completing insertion of each of the interface cards, related wiring and transmission flat cables are connected to insertion slots of the corresponding interface cards according to power supply and transmission requirements. Finally, after testing for normal operation of the host computer, assembly of the complete is complete.
Referring to FIG. 1, which shows a schematic view of an embodiment depicting a prior art host computer, wherein a host computer 10 mainly includes a case 101 that serves to provide space for primarily mounting various structural components. Moreover, the case 101 is further provided with the function to protect each of the structural components. In addition, a front surface of the case 101 is the operation panel which enables installing a plurality of operating keys, and provides insertion slots for peripheral equipment. FIG. 1 further shows that the interior of the case 101 in general provides a flat surface that enables assembling a motherboard 102 thereto. Regarding computer cases of prior art, because the side portion is provided with a relatively large area which enables assembling the large motherboard 102, thus, the assembled motherboard 102 is mainly positioned close to a side portion of the case 101. However, during the course of assembling the host computer 10, in general, after an installer dismantles a cover panel of one side of the case 101, then the motherboard 102 is installed within the case 101, and because of the restricted interior space of the case 101, the installer must be extremely careful during assembly in order to avoid scuffing a surface of the motherboard 102 and other component members attached to the surface thereof. Moreover, a majority of the cases 101 are fabricated from metal components, which results in many metallic angles being formed in the interior of the case 101, hence, during the course of assembly, any slight inadvertent movement by the installer can extremely easily result in scratching of the hands of the installer, or inadvertently scuffing the motherboard during the course of assembling the motherboard.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 2 and FIG. 2A, which show external elevational views of an embodiment of a motherboard fixing device of the present invention, wherein a motherboard fixing device installed within a case 201 of a host computer 20 primarily comprises a lower retaining wall 31, an upper retaining wall 32 and a retaining panel 33. The lower retaining wall 31 is installed to a bottom surface of the case 201, and position of installation is close to a side 202 of the case 201, thereby forming an insertion groove 203 with the side 202 after completing the installation, and depth of the insertion groove 203 is the same as height of the lower retaining wall 31. Furthermore, a plurality of elastic catch devices 311 are configured on a surface of the lower retaining wall 31. A fixing end 3111 fixed to the surface of the lower retaining wall 31 is located at an end of each of the catch devices 311, and another end forms a protruding point 3112. After fixing the fixing ends 3111, the protruding points 3112 protrude within the insertion groove 203 to an appropriate distance, and applying force to the protruding points 3112 causes an elastic displacement thereof towards the exterior of the insertion groove 203. Furthermore, because the fixing ends 3111 are already fixed, thus, the protruding points 3112 are provided with a restoring counterforce toward the interior of the insertion groove 203. Referring again to FIG. 2 and FIG. 2A, the upper retaining wall 32 is installed to or directly formed with above the lower retaining wall 31, and position of the upper retaining wall 32 is relative to that of the lower retaining wall 31. A plurality of catch devices 321 are located on an upper portion of the upper retaining wall 32, function of which is identical to that of the catch devices 311 on the surface of the retaining wall 31. Furthermore, a plurality of position fixing points 322 are configured close to area of the catch devices 321, and the plurality of position fixing points 322 protrude out from a surface of the upper retaining wall 32, thereby enabling fastening down with screws or riveting together using rivets to complete assembly. The retaining panel 33 independently forms a plate, and a plurality of assembly holes 331 are defined in a surface of the retaining panel 33, and the plurality of assembly holes 331 enable assembling a motherboard (not shown in FIG. 2 and FIG. 2A). Furthermore, a bottom edge of the retaining panel 33 is bent to form an assembling portion 332 of appropriate width, and a plurality of keyhole shaped position fixing holes 333 are formed in an upper edge of the retaining panel 33.
Referring to FIG. 3, FIG. 3A, and FIG. 3B, which show enlarged schematic views of structural members of the motherboard fixing device of the present invention, wherein after completing disposition of the catch devices 311 of the lower retaining wall 31, the protruding points 3112 protrude within the insertion groove 203, and applying force enables effecting an elastic displacement thereto. Referring again to FIG. 3, FIG. 3A, and FIG. 3B, the position fixing points 322 configured on the upper retaining wall 32 protrude out the surface of the upper retaining wall 32 after completing disposition thereof. Recesses 3221 formed after disposition of the position fixing points 322 enable mutually assembly with the position fixing holes 333 of the retaining panel 33. Referring again to FIG. 3, FIG. 3A, and FIG. 3B, the retaining panel 33 enables assembling a motherboard 40 to the surface thereof, and after assembling the motherboard 40, other peripheral interface card devices can then be consecutively inserted within insertion grooves provided by the motherboard 40.
Referring to FIG. 4, and FIG. 4A, which show schematic views of the first embodiment according to the present invention, wherein a completed assembly of the retaining panel 33 and the motherboard 40 forms an integrated body, and after the motherboard 40 has been fixed to the retaining panel 33, then the retaining panel 33 needs only be assembled to the case 201 to complete assembly. When assembling, the bottom edge of the retaining panel 33 (that is, the assembling portion 332) is first inserted into the insertion groove 203, thereby enabling the assembling portion 332 to fall exactly into the insertion groove 293, whereupon the surface of the retaining panel 33 presses down on each of the catch devices 311 on the surface of the lower retaining wall 31, and because each of the catch devices 311 are provided with an elastic property, thus, a clamping effect is formed at the bottom edge of the retaining panel 33.
Referring to FIG. 5, which shows a schematic view of the second embodiment of the motherboard fixing device according to the present invention, wherein after disposition of the bottom edge (that is, the assembling portion 332) of the retaining panel 33, each of the position fixing holes 333 of the upper edge of the retaining panel 33 can mount exactly on each of the position fixing points 322 of the upper retaining wall 32. After an installer has made sure each of the position fixing points 322 of the position fixing holes 333 have been completely fixed, then the retaining panel 33 is transversally pushed to displace the retaining panel 33 sideward, thereby effectively fixing the retaining panel 33, primarily using positional coordination between the position fixing points 322 and the position fixing holes 333, and because the position fixing holes 333 are of keyhole shaped, thus, hole portions having relatively large apertures are respectively presented to the position fixing points 322 when the position fixing holes 333 are first mounted thereon. When the user transversally pushes the retaining panel 33, then hole portions of relatively small aperture of the position fixing holes 333 are pushed towards the position fixing points 322, as depicted in FIG. 3, FIG. 3A, and FIG. 3B, and the recesses 3221 of the position fixing points 322 are used to fixedly clasp the retaining panel 33 to achieve fixing effectiveness thereof. After the retaining panel 33 has been fixedly clasped, as shown in FIG. 6 depicting a schematic view of the third embodiment according to the present invention, wherein after fixedly positioning the retaining panel 33 using the position fixing points 322, then the position fixing points 322 are positioned with the relatively small hole portions of the position fixing holes 333.
According to the aforementioned description, it can be appreciated that the motherboard fixing device of the present invention primarily provides for initial assembly of a motherboard to the retaining panel 33, whereupon an inserting method is used to dispose the retaining panel 33 to the case 201 of the host computer 20 to complete assembly. Accordingly, an installer can first complete assembly of the motherboard and related interface cards outside the case 201, whereupon the entire retaining panel 33 can be assembled to the case 201, and finally, the installer can implement connecting of wiring, transmission wires, and so on, thereby effectively preventing damage to the motherboard during the course of assembling and disassembling, moreover, assembly space is not restricted by the computer case 201.
In conclusion, according to the aforementioned embodiments, the motherboard fixing device of the present invention assuredly achieves the objectives of enabling convenient and fast installation of a motherboard and effectively preventing the motherboard from being damaged during the course of assembly. Furthermore, effectiveness, practicability and advancement of the motherboard fixing device of the present invention clearly comply with essential elements as required for a new patent application.
