The present invention allows each member to protect the hard disk drive to be assembled in a bolt-free manner, so that the disassembly / assembly process is not only simple, but also a bolt-free external hard disk drive case that does not require a separate tool. It is about.

In general, a hard disk drive (HDD) is used as an auxiliary memory device for storing data in a computer such as a personal computer (PC) or a notebook computer, and a state in which data is moved or a large amount of data is stably stored. Use an external hard disk drive to make it easier to move around.

An external hard disk drive is usually 2.5 inches or 3.5 inches in size. A hard disk drive is a disk for storing data, and a magnetic head for recording or playing back or reading data on the disk. Head, a spindle motor for rotating the disk at high speed, a printed circuit board for controlling them, an interface for connecting a hard disk drive to a computer main body, and the like. .

The external hard disk drive has a complicated structure inside, and the components installed therein are placed on the outside of the parts so that the parts are not damaged or damaged by an impact or external force.

1 is an exploded perspective view showing a conventional external hard disk drive case. As shown in the figure, the case 10 has a space for accommodating a hard disk drive therein by combining the front case 10b and the rear case 10c on both sides of the center case 10a positioned at the center. The case 10 is formed in a rectangular shape having a size of 2.5 inches or 3.5 inches, and rotatably couples two supporters 30 to the bottom surface of the case 10.

The right side of the center case 10a is coupled to the display 11 for displaying the operating state of the hard disk drive, and the left side is coupled to the various interface terminals that exchange data with the computer.

On the right side of the center case (10a) is installed a display (11) indicating the operating state of the hard disk drive, the display coupling hole 12 to which the display 11 is coupled to form a vertical direction, the left side of the power cable, An interface coupling hole 13 for installing terminals for connecting an interface and an operation of a hard disk drive, such as a USB (Universal Serial Bus) terminal and a power switch, is formed.

The center case 10a forms a belt-shaped step 14 having a predetermined thickness at the center of the outer side of the rectangle, and two pedestal insertion grooves 15 for accommodating the pedestal 30 at the bottom of the center case 10a. It is formed to a certain height, and in the center of the pedestal insertion groove 15 to form a pedestal insertion hole 16 is coupled to the bush 31 to move the pedestal 30 vertically.

In addition, a plurality of support protrusions 17 for supporting a hard disk drive are fixed to the upper surface of the pedestal insertion groove 16, and a case fastening hole for bolting the front case 10b and the rear case 10c to the bottom surface thereof ( A plurality of 18) is formed.

The front case 10b is a fastening hole corresponding to the case fastening hole 18 of the center case 10a on the bottom surface in a state of being fitted to the outside of the center case 10b while being in contact with the step 14 of the center case 10a. (Not shown in the figure) and a plurality of bolts are fastened to the fastening hole, and the stepped portion 14, the display coupling hole 12 and the interface coupling hole 13 of the center case (10a) Each has a corresponding shape.

The rear case 10c is in contact with the step 14 of the center case 10a in the same manner as the front case 10b while being fitted to the outside of the center case 10a on the bottom surface of the case fastening hole of the center case 10a. Forming a plurality of fastening holes (19) corresponding to the (18), and provided with bolts to be fastened to the fastening hole, the step 14, the display coupling hole 12 and the interface coupling hole of the center case (10a) It consists of a shape corresponding to (13).

The buffer plate 40 is formed in a rectangular shape inserted into the center case 10a, and the material is made of a synthetic resin material that absorbs shocks to alleviate the shock applied to the hard disk drive and to remove heat generated from the hard disk drive. A plurality of through holes 41 are formed, and a plurality of long holes 42 are bolted to correspond to the fixing holes formed in the hard disk drive.

The hard disk drive is fixed to the space formed between the front case 10b and the rear case 10c so as not to move, and the long hole 42 of the buffer plate 40 is disposed on one surface of the hard disk drive HDD. Tighten with bolts corresponding to drive fixing holes.
