A panel 41 is coupled to a front side of the first plate 13. The third plate 15 is provided with a plurality of open holes 153 used for fixing a fan through screws or guiding air.
Please refer to FIGS. 1 and 5. A computer housing of a second preferred embodiment according to the present invention comprises a bottom plate 11, four fixing rods 12′, a first plate 51, a second plate 52, a third plate 53, a fourth plate 54, a upper plate 17, a first supporting frame 18, a second supporting frame 19, four column type magnets 55 and a panel 41.
The computer housing of the second embodiment and the computer housing of the first embodiment are provided with the same bottom plate 11, four fixing rods 12′, upper plate 17, first supporting frame 18, second supporting frame 19 and panel 42, and the coupling structures of the components are approximately the same; the fixing rod 12′ is also provided with screw holes 121′, a first column type groove 122′ and a second column type groove 123′. But, the cross sections of the first column type groove 122′ and the second column type groove 123′ are wider to be used for accepting the column type magnet 55; first coupling portions 511, 541 and second coupling portions 512, 542 on two ends of the first plate 51 and the fourth plate 54 of the computer housing of the second embodiment all are a plain plate type and are not bended to be “U” type; first coupling portions 521, 531 and second coupling portions 522, 532 on two ends of the second plate 52 and the third plate 53 all are bended to be “L” type to cover one corner of the fixing rod 12′ and not bended to be “U” type; the first panel 51 is also provided with a plurality of open holes 513, 514 and 515 used for respectively coupling to external panel buttons or external receptacles; the third plate 53 is also provided with a plurality of open holes 533 used for allowing screws to fix a fan or guiding air. Furthermore, the computer housing of the second embodiment further comprises four column type magnets 55 respectively accepted in accepting spaces constituted by the first column type grooves 122′ and the second column type grooves 123′ of the four fixing rods 12′. The four fixing rods 12′, the first plate 51, the second plate 52, the third plate 53 and the fourth plate 54 are all made from iron material and have iron ingredients.
As to the computer housing of the second embodiment according to the present invention, the four fixing rods 12′ are allowed to respectively attract the first coupling portions 511, 521, 531, 541 and the second coupling portions 512, 522, 532, 542 of the first plate 51, the second plate 52, the third plate 53 and the fourth plate 54 by means of magnetic attraction force of the column type magnets 55 to complete the computer housing assembly operation easier. As FIG. 7 shows, take the structure of coupling the first coupling portion 511 of the first plate 51 and the second coupling portion 522 of the second plate 52 to an outer side of the fixing rod 12′ as an example to explain. When the column type magnet 55 is accepted in the accepting space constituted by the first column type groove 122′ and the second column type groove 123′ of the fixing rod 12′, it leads to that the fixing rod 12′ is also provided with attraction force by means of the magnetic force of the column type magnet 55 so that the outer side of the fixing rod 12′ can respectively attract the first coupling portion 511 of the first plate 51 and the second coupling portion 522 of the second plate 52 to enable the first coupling portion 511 and the second coupling portion 522 to respectively cover the outer side of the fixing rod 12′.
When the components of the plate combination type computer housing of the present invention are not assembled together, they all very easy to be collected into a packing body with the smallest volume because they are all plates. Whereby, the space occupied by the computer housing can substantially be reduced when they are stored or transported to be beneficial for reducing the transportation cost and saving the storage space.
The plate combination type computer housing of the present invention is provided with simple six-plates type components and four fixing rods such that the number of molds for manufacturing the housing can be reduced to save the production cost. Besides, it is unnecessary to process screw locking to enable the four fixing rods to be respectively coupled to the first plate, the second plate, the third plate and the fourth plate so that the assembly is easier to substantially reduce the assembly time and the modeling design of the outlook of the computer housing is not influenced because there are no screws and fixing rods to be exposed outside the computer housing.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
