DETAILED DESCRIPTION OF THE INVENTION
In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
With referring to FIG. 1, the exploded view of the present invention is illustrated. The present invention has the following elements.
An assembling unit 23 has a frame hole 231 at a front side thereof. A plurality of communication ports 232 are installed within the frame hole 231 and are electrically connected to a circuit unit 233. The assembling unit 23 has an opening 234 which runs across at least three sides of the assembling unit 23. The opening 234 causes the assembling unit 23 being divided into an upper portion 235 and a lower portion 236. Two ribs 237 serve to divide the frame hole 231 from the opening 234. The assembling unit 23 is made of flexible material, such as plastic, cloth, etc. A chain 25 is movably installed to the opening 234. One end of the chain 25 has a head 251. By the movement of the chain 25, the assembling unit 23 performs the operation of the separation and closing. The chain 25 can be combined to the assembling unit 23 by adhesion, hot-pressing, seaming, etc.
A hard disk 22 is combined to the circuit unit 233. The circuit unit 233 has holes corresponding to a bottom of the hard disk 22 so that the hard disk 22 is combinable to the circuit unit 233 by using fixing units 26. The frame hole 231 at a front end of the assembling unit 23 has a slot plate 27 which has a specification suitable for the communication ports 232. The slot plate 27 serves to provide a supporting force to the hard disk 22. Other supporting to the hard disk 22 will be described hereinafter.
An upper cover 20 combines to an upper side of the upper portion 235 of the assembling unit 23.
A base 21 combines to a lower side of the lower portion 235 of the assembling unit 23 and is almost identical to the cover 20. The upper cover 20 and the base 21 are formed with a space for receiving a data storage unit, such as the hard disk 22 and a circuit unit 233. Pads can be installed between the upper cover 20 and the hard disk 22 and between the base 21 and the hard disk 22 for vibration absorption and providing support to the hard disk 22. The upper portion 235 and lower portion 235 can be combined to the assembling unit 23 by adhesion, hot-pressing, seaming, etc. Thus, the upper cover 20 and the base 21 are formed as an outer cover to cause the hard disk 22 to be supported therein.
Stripes can be installed between the upper cover 20 and the upper portion 235 and between the lower portion 235 and the base 21 for increasing contact area. The colors of the stripes 24 will beautify the appearance of the whole structure.
Referring to FIG. 3, the assembly of the present invention is illustrated. The hard disk 22 is assembled to the circuit unit 233. The circuit unit 233 and the communication ports 232 are fixed to the frame hole 231 at a front side of the assembling unit 23. The slot plate 27 is installed in the frame hole 231. The pads are installed at inner sides of the upper cover 20. Above mentioned components are enclosed in the space formed by the upper cover 20, the base 21 and the assembling unit 23. The chain 25 serves to open or close the opening 234 so that the upper cover 20 and the base 21 are opened and closed.
With referring to FIGS. 4 and 5, FIG. 4 shows that the chain 25 is closed. FIG. 5 shows a lateral view of the present invention. The communication ports 232 are hidden in the body. The structure is smooth without protrusion. In the present invention, a portable hard disk is received in a cover with a beautiful outlook. It only need open or close the chain for repair and maintenance with less cost and assembly time.
In the present invention, the upper cover 20 and base 21 may be made of plastic, metal, or leather or the combination of above materials.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
