Description

  The present invention relates to an electronic device and a mounting mechanism, and in particular, an electronic device characterized by an impact-resistant mounting structure of a disk device (particularly a hard disk device, HDD: Hard Disk Drive) in a portable electronic device such as a notebook personal computer. The present invention relates to an apparatus and a mounting mechanism.

  Here, the disk device is a device for recording and / or reproducing information on a disk-shaped recording medium, and includes a magnetic disk device, an optical disk device, a magneto-optical disk device, a hard disk device (HDD), and a floppy (registered trademark) disk. Device (FDD), CD-ROM drive device, etc.

  In recent years, with the improvement in performance of notebook personal computers, notebook personal computers have come to be equipped with hard disk devices that have a larger storage capacity and higher speed than floppy (registered trademark) disk devices. ing.

  Here, a hard disk drive mounting structure in a conventional notebook personal computer will be described with reference to FIG.

FIG. 10 is an exploded perspective view of a notebook personal computer 50 equipped with a hard disk device. In FIG. 10, an HDD (behind the right front surface of the casing 51 of the notebook personal computer 50) The HDD 52 is attached to the storage unit.

  In this case, the HDD 52 containing the disk-shaped storage medium, head, motor, etc. is fixed to the HDD mounting bracket 53 with screws 54 so that the printed circuit board side of the HDD 52 is on the HDD cover 57 side. 53 is fixed to the casing 51 by screws 55.

  Further, after arranging an FPC (Flexible Printed Circuit) cable 56 attached to the casing 51 so as to be electrically connected to the printed circuit board of the HDD 52, the HDD cover 57 was slid to cover the HDD housing portion of the casing 51. After that, the structure is fixed to the casing 51 with a screw 58, and no shock absorber or the like is used.

  However, in the case of a magnetic disk device mounted on a laptop computer or the like, a plurality of anti-vibration rubbers are provided between the side surface of the magnetic disk device and the housing to generate positioning errors due to vibration of the magnetic head. It has been proposed to prevent (refer to Japanese Patent Application Laid-Open No. Hei 3-241583 if necessary). In particular, by using a combination of a plurality of anti-vibration rubbers having different temperature dependence of damping characteristics, a wide range of temperature changes can be achieved. It is also described that sorbosein (Sorbothane: trade name) made of ether-based polyurethane is used as a vibration-proof rubber.

In addition, in the case of a fixed magnetic disk device used in a large-sized computer, in order to enable the operator to carry it, the exterior of the magnetic disk device body is sandwiched with a plurality of cushioning materials such as cushioning rubber between the upper and lower bottom surfaces and the side surface. A vague idea has also been proposed in which the constraint on vibration shock is greatly relaxed by storing in a box (see Patent Document 1 if necessary).
Japanese Utility Model Publication No.59-135504

  However, in notebook personal computers equipped with HDDs as described above, the HDD itself has become higher in definition and weight as the recording density of the HDD increases, and the frequency of portable use has increased with the reduction in weight. In addition, the mechanical strength decreases with the increase in definition, and the occurrence of a failure due to an impact during carrying or operation is a problem.

  For example, a conventional HDD is fixed to the casing of a notebook personal computer with screws, so that when a shock is applied during carrying or operation, the magnetic head comes into contact with the disk-shaped storage medium, and the disk-shaped storage medium is scratched. This damage causes data corruption.

  On the other hand, when the HDD device has a floating structure, during the search operation (Seek) in which the magnetic head searches the recording area, the head position is accurately set by residual vibration accompanying rotation of the disk-shaped storage medium. There is a problem that a reading error occurs.

  Further, in the case of the above-described laptop computer or the like, a vibration isolating rubber is provided on the side surface of the magnetic disk device in order to provide the vibration isolating performance. There is no special consideration for sex and it does not solve the problem.

  Further, in the case of the above-described portable fixed magnetic disk device, it is not assumed to be used by a general user, and is considerably larger than an HDD device mounted on a notebook type personal computer, and has a reduced space or light weight. However, this does not suggest a specific measure for a notebook personal computer that is used by general users and that is restricted in terms of space reduction or weight reduction.

Therefore, a data corruption failure can be prevented, thereby improving the reliability.

  The reason why each vibration and / or shock absorbing material is divided into small pieces is the result of various experiments. As a result of using various large vibration and / or shock absorbing materials, it is more resistant to vibration. This is because it has been recognized that the property and / or impact resistance is improved.

In the first embodiment, since the sheet material 41 is used, even if condensation occurs, the vibration and / or shock absorbers 42 ₁ to 43 ₃ that face the printed circuit board side of the HDD 34 are caused. Therefore, reliability is improved because no short circuit occurs.

  In the first embodiment, a polyester sheet material is used as the sheet material 41. However, the sheet material 41 is not limited to a polyester material, and any insulating material having a small friction coefficient may be used.

In this case, the soft vibration and / or the shock absorbing material 411 alone absorbs the shock softly. In the case of a strong shock, the soft vibration and / or the hard vibration newly added with the shock that cannot be absorbed by the shock absorbing material 411 are added. In addition, since it has a two-stage structure that is absorbed by the shock absorber 412, it can effectively cope with a wide range of impacts from weak impacts to strong impacts as compared to the first embodiment. .

FIG. 8 is a perspective view showing a main part of another modification of the second embodiment.

  In another modification shown in FIG. 8, the relative hardness of the vibration and / or shock absorbers 431 and 432 is different. For example, the vibration and / or shock absorber 431 is relatively harder than the vibration and / or shock absorber 432, or vice versa.

  Further, the vibration and / or shock absorbing material provided not only on the lid member side but also on the upper bottom surface 22 side of the HDD housing portion 35 may be a two-stage structure.
