Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of vibration- and dust-proofing device for an external hard disk, particularly applied to an external hard disk used in a personal computer or a notebook personal computer to prevent an internal magnetic disk from being damaged by vibration of an external environment. Related to the device.

[Prior art]

 As shown in FIG. 4, a conventional circumscribing hard disk B includes a magnetic disk B1 housed in a case B5 in an openable manner and a magnetic head B2, and the inside of the hard disk B is rotated by high-speed rotation of the magnetic disk B1. The magnetic head B2 separates the data recorded on the magnetic disk B1 by the magnetic head B2 into a signal by using a magnetically sensitive method by generating an air current to separate the magnetic head B2 from the outer surface of the magnetic disk B2. The signal is transmitted to a memory or a computing unit. Thus, when the magnetic disk B1 rotates at a high speed, if the hard disk is vibrated, the drifting force of the magnetic head B2 floating on the outer surface of the magnetic disk B1 is interfered, and the magnetic head B2 is thereby directly magnetized. In some cases, the surface of the magnetic disk B1 was damaged by collision with the disk B1.

As described above, the external hard disk is easily damaged by the internal magnetic head B2 due to the vibration. In addition, since the inside of a general circumscribing hard disk is an open space, internal devices were easily destroyed by ashes entering from the outside. For this reason, the external hard disk was generally fixed on the desktop and was not moved, and could not be freely carried or mailed. To sum up the cause, the internal equipment is not provided with a protective device, which causes external vibrations and ash dust to enter. Therefore, it was necessary to provide a vibration and dust proof device on the external hard disk.

[0004]

[Problem to be Solved by the Invention] The main object of the invention is to prevent the external hard disk from being damaged due to the external environment by providing an anti-vibration and dustproof device for protecting the hard disk.

[0005]

[Means for Solving the Problems]

 The invention of claim 1 is composed of a hard disk having an upper lid, a sealed case, and a base sheet, and the base sheet is connected to a power supply port and a connection port of the hard disk by a power supply line and a signal bus to prevent an externally connected hard disk. In the anti-vibration device, a fixed block is attached to a sealed case of the hard disk, and the hard disk and the case are formed of a flexible protective pad composed of an upper protective sheet, a lower protective sheet, and a frame protective sheet having a hollow portion. It is a vibration- and dust-proof device for a circumscribing hard disk, characterized by being encapsulated in a hard disk. The invention according to claim 2 is characterized in that the external port is composed of a flexible substrate, a PC board, and an external power plug, and the hard disk is replaceable. It is a vibration proof device.

[0006]

[Embodiment of the invention]

 As shown in FIG. 3, a general circumscribing hard disk case D has a hard disk B in which an internal device including a magnetic disk and a magnetic head is openly accommodated in a case B5. The signal bus D1 and the power supply line D2 are inserted and connected to the connection port B3, and no device is provided for protecting the hard disk B from vibration. Therefore, the hard disk B is easily affected by the external environment and generates vibration. In addition, when the hard disk was operated in an open space, ash dust in the surrounding environment could easily enter and damage the components inside the hard disk B.

As shown in FIG. 1, the present invention is composed of a top cover A, a hard disk B and a bottom seat C. The hard disk B itself is pre-enclosed in a sealed case, and a base sheet C The connection port C14 and the power supply port C16 are connected to the flexible board C16 and the power supply line D2, and the lower protection pad 23 of the soft protection pad 2 is provided between the hard disk B and the base sheet C. The fixing block 1 is further screwed around the outer periphery of the hard disk B, and the hollow portion of the frame protection sheet 22 surrounds the outer periphery of the hard disk B and the fixing block 1. The protective sheet 21 is covered, and finally the upper cover A is fixed on the base sheet C, thus the circumscribed hard disk drive of the present invention. A disk vibration and dust proof device is formed.

[0008] A PC board C13 is connected to the circumscribed port C1 provided on the base sheet C of the present invention, and an external power plug C12 and a power switch 12 are separately provided. Used to supply power for B operation.

In the embodiment shown in FIG. 2, the flexible protective pad of the present invention is composed of a plurality of pillars, and the flexible protective pad 2 has an upper protective sheet 21, a frame protective sheet 22, and a lower protective sheet in the embodiment of FIG. The same effect as that of the sheet 23 is achieved. For this reason, the soft protection pad of the present invention does not require a specific outer shape, and is composed of a soft material, and this soft material can be installed on the four circumferences of the fixing block 1 and on the upper surface and the lower surface of the hard disk B. It is considered as the soft protection pad of the invention.

As described above, the main function of the present invention is to protect the four circumferences of the hard disk B using the fixed block 1 and the frame protection sheet 23, and to provide the upper protection sheet provided above and below the hard disk B. The lower and upper protective sheets 23 and 23 protect the upper and lower surfaces of the hard disk B, thereby reducing the degree of vibration received by the hard disk B, and protecting the internal structure of the hard disk B with a sealed case so that the ash dust and the hard disk B can be protected. To prevent intrusion into

[0011]

[Effect of the invention]

 In the soft protective pad 2 of the present invention, the upper protective sheet 21, the lower protective sheet 23, and the frame protective sheet 22 all have flexible characteristics, and therefore, when the external hard disk case D is subjected to vibration, The protection pad 2 achieves the function of reducing the vibration of the hard disk B. When vibration occurs in the circumscribed hard disk case D, unless the volume of the hard disk B in the circumscribed hard disk B is increased by the fixing block 1, the hard disk B swings and the internal device is easily damaged. . Therefore, according to the present invention, the fixed block 1 outside the hard disk B reduces the space in which the hard disk B can oscillate, thereby reducing the degree of sway of the hard disk B in the external hard disk case D. B is stably installed between the upper lid A and the base sheet C. In addition, the sealed case of the hard disk prevents ash dust from entering the magnetic head B2 and other components in the hard disk B.
