Description
本発明は、強い衝撃が加わっても内蔵されたハードディスクドライブの衝撃緩衝部材がその衝撃を吸収した圧縮、変形後には速やかに元の形状に回復するようにした携帯型情報処理装置に関するものである。 The present invention relates to a portable information processing apparatus in which a shock absorbing member of a built-in hard disk drive absorbs the shock even after a strong shock is applied and quickly recovers to its original shape after being deformed. .
近年、ノート型パーソナルコンピュータ（以下、ノートパソコンという）の小型化、軽量化が進み、携帯時に誤って落下等による非常に大きな衝撃を受ける機会も増加している。ノートパソコンに内蔵されているハードディスクドライブ（以下、ＨＤＤという）にはノートパソコンに記憶されているほとんどのデータ、あるいはノートパソコンを動作させる基本ソフトウェアであるオペレーティングシステム（ＯＳ）が記録されており、そのために、ＨＤＤの動作中に、特にディスクの記録面に対して垂直な方向に衝撃力が加わると、ヘッドがスペーシング量以上に変位してディスク表面を叩くヘッドスラップと呼ばれる現象が起こり易い。ヘッドスラップは、ディスクの記録表面或いはヘッドの物理的損傷を招き、少なくともディスクの損傷部に記録されていたデータの記録再生ができなくなる。あるいは、ＯＳ記録部が損傷を受ければノートパソコン自体が動作不能になり、最悪の場合にはディスクの全記録面が使用不可、つまりＨＤＤが損壊する。 In recent years, a notebook personal computer (hereinafter, referred to as notebook PC) miniaturization of, progress in lightweight, very big shock opportunity by dropping or the like by mistake when carrying is also increased. The hard disk drive built into notebook computer (hereinafter, referred to as HDD) for most of the data stored in the notebook computer or has an operating system (OS) is recorded a basic software for operating the laptop, therefore In particular, when an impact force is applied in the direction perpendicular to the recording surface of the disk during the operation of the HDD, a phenomenon called head slap in which the head is displaced beyond the amount of spacing and hits the disk surface is likely to occur. The head slap causes physical damage to the recording surface of the disk or the head, and at least data recorded on the damaged part of the disk cannot be recorded or reproduced. Alternatively, if the OS recording unit is damaged, the notebook personal computer itself becomes inoperable, and in the worst case, the entire recording surface of the disk cannot be used, that is, the HDD is damaged.
以下、従来のノートパソコンにおいて、衝撃からＨＤＤを保護する衝撃緩衝装置について図を用いて説明する。 Hereinafter, an impact buffer device for protecting an HDD from an impact in a conventional notebook computer will be described with reference to the drawings.
図６は衝撃緩衝部材で覆われたＨＤＤがノートパソコンに収容されている図である。 FIG. 6 is a diagram in which the HDD covered with the shock absorbing member is accommodated in the notebook computer.

The display unit 14 is an HDD main body.
図６（ｂ−１）〜（ｂ−３）において、１４はＨＤＤ本体、１６は衝撃緩衝部材であり、ＨＤＤ１４の平面部の上面、下面の各４角に１個（１６Ｕ、１６Ｄ）、４つ側面各中央に１個（１６Ｌ、１６Ｒ、１６Ｆ、１６Ｂ）がＨＤＤを包み込むように配置され、さらにアルミニウム等の金属材でできた外枠ケース１７にＨＤＤ１４と共に収容され、衝撃緩衝部材１６と外枠ケース１７によりＨＤＤ１４の衝撃緩衝装置１５′を構成し、図６（ａ）のようにノートパソコン本体１２に実装されている。衝撃緩衝部材１６の材質は弾性を有する特殊ゴムや発泡ポリウレタンなどの衝撃緩衝材で構成されておりＨＤＤ１４にかかる衝撃を緩和する。 6 (b-1) to 6 (b-3), reference numeral 14 denotes an HDD main body, and 16 denotes an impact buffering member, one at each of the four corners of the upper surface and the lower surface of the HDD 14 (16U, 16D), One side (16L, 16R, 16F, 16B) is arranged so as to wrap the HDD, and is housed together with the HDD 14 in an outer frame case 17 made of a metal material such as aluminum. The shock absorber 15 'of the HDD 14 is constituted by the frame case 17, and is mounted on the notebook personal computer main body 12 as shown in FIG. The material of the shock absorbing member 16 is made of a shock absorbing material such as special rubber having elasticity or foamed polyurethane, and relieves the shock applied to the HDD 14.
図７はノートパソコン１１を誤って床面、机上面等に落下させたときの衝撃緩衝装置１５′に収容されたＨＤＤ１４、衝撃緩衝部材１６のようすを模式的に示した図６（ｂ―３）のＡ−Ａ′の断面図である。 FIG. 7 schematically shows the appearance of the HDD 14 and the shock absorbing member 16 accommodated in the shock absorbing device 15 'when the notebook personal computer 11 is accidentally dropped on the floor surface, the desk surface or the like. ) is a sectional view of the a-a 'of.
なお、図７においては、ノートパソコン１１を誤って落下させた場合についての説明図であるが、説明の便宜上、ＨＤＤ１４を収容した衝撃緩衝装置１５′を落下させたように図示している。 FIG. 7 is an explanatory diagram when the notebook personal computer 11 is accidentally dropped, but for the sake of convenience of explanation, the shock absorbing device 15 ′ housing the HDD 14 is illustrated as being dropped.

That is, the shock absorbing member 16L to the shock absorbing member 16D disposed on the lower surface of the HDD14 disposed on the side of the HDD14 and HDD14 as in FIG. 7 (c), due to friction with the 16R, the impact of the drop remains contracted It does not recover to the state before receiving it.

These shock absorbing members 16 are housed together with the HDD 14 in an outer frame case 17 made of a metal material such as aluminum. Reference numeral 18 denotes a low friction member, which is a material having a relatively small sliding friction coefficient between the low friction member 18 and the housing of the HDD 14 compared to the sliding friction coefficient between the shock absorbing member 16 and the housing of the HDD 14 itself. of a sheet material, low-friction member 18 in the present embodiment, the shock absorbing member 16L, 16R (some have are not shown in Figure 1 16F, 16B) is or adhesive on the side in contact with the housing of the HDD14 Affixed with double-sided tape. The shock absorbing device 15 of the HDD 14 is constituted by the shock absorbing members 16L and 16R (or 16F and 16B) to which the low friction member 18 is attached and the outer frame case 17.

Other shock absorbing member 16U, 16D shall surface in contact with either the casing side or the outer frame casing 17 side of the HDD14 is fixed by adhesive or double-sided tape.
図２はノートパソコンを誤って床面、机上面等に落下させたときの衝撃緩衝装置１５に収容されたＨＤＤ１４、衝撃緩衝部材１６のようすを模式的に示した断面図である。 Figure 2 is the floor by mistake laptop, a cross-sectional view schematically showing the shock absorbing device 15 HDD 14 housed in the state of the shock absorbing member 16 when fallen on a desk surface or the like.
なお、図２においてはノートパソコン１１を誤って落下させた場合についての説明図であるが、説明の便宜上、ＨＤＤ１４を収容した衝撃緩衝装置１５を落下させたように図示している。 Note that FIG. 2 is an explanatory diagram when the notebook personal computer 11 is accidentally dropped, but for the sake of convenience of explanation, the shock absorber 15 containing the HDD 14 is shown as dropped.
以上のように構成された本発明のＨＤＤ１４を収容した衝撃緩衝装置１５のノートパソコン落下時における詳細について図１、図２を用いて説明する。 Details of the shock absorber 15 containing the HDD 14 of the present invention configured as described above when the notebook computer is dropped will be described with reference to FIGS.
まず、ＨＤＤ１４が実装されているノートパソコン本体の下面が落下によって（図２（ａ））、外枠ケース１７に衝撃が加わる。さらにＨＤＤ１４の下面の衝撃緩衝部材１６Ｄは落下の衝撃により図のように圧縮、変形されてＨＤＤ１４に加わる衝撃を緩衝する（図２（ｂ））。次に弾性を有する衝撃緩衝部材１６Ｄはその復元力と低摩擦部材１８Ｌ、１８Ｒとの相乗作用によって元の状態、つまりノートパソコン本体の落下前（図２（ａ））の状態に速やかに回復する（図２（ｃ））。 First, an impact is applied to the outer frame case 17 when the lower surface of the notebook personal computer main body on which the HDD 14 is mounted falls (FIG. 2A). Further, the impact buffering member 16D on the lower surface of the HDD 14 is compressed and deformed as shown in the figure by the impact of the fall to buffer the impact applied to the HDD 14 (FIG. 2B). Next, the shock-absorbing member 16D having elasticity quickly recovers to its original state, that is, the state before the notebook personal computer body is dropped (FIG. 2A) by the synergistic action of the restoring force and the low friction members 18L and 18R. (FIG. 2 (c)).
以上のように本実施の形態によれば、ノートパソコン本体の落下によってＨＤＤ１４に加わる衝撃を緩衝し、圧縮、変形された後の衝撃緩衝部材１６Ｄは、その回復を阻害するＨＤＤ１４の筐体と衝撃緩衝部材１６Ｌ、１６Ｒ（あるいは１６Ｆ、１６Ｂ）との摩擦が、その間に配した低摩擦部材１８により小さくなって速やかに落下前の状態に回復する。これにより従来の課題である衝撃緩衝部材の圧縮、変形状態が長く継続することによる材料の経年劣化を早める要因を取り除き、衝撃を吸収した衝撃緩衝部材が圧縮、変形後に速やかにその元の形状を回復し、次のＨＤＤに強い衝撃が加わる事態に備えることができる。 As described above, according to the present embodiment, the shock applied to the HDD 14 due to the drop of the notebook personal computer body is buffered, and the shock absorbing member 16D after being compressed and deformed has the housing and the shock of the HDD 14 that impede its recovery. The friction with the buffer members 16L and 16R (or 16F and 16B) is reduced by the low friction member 18 disposed therebetween, and quickly recovers to the state before dropping. Thus the compression of the shock absorbing member is a conventional problem, eliminate the cause to accelerate the aging of materials due to the deformation state continues long, shock absorbing member has absorbed the shock compression, quickly its original shape after deformation Can be prepared for a situation where a strong impact is applied to the next HDD.
なお、外枠ケース１７はアルミニウム等の金属材で構成するとしたが、他の材料、例えば樹脂材料であってもよいことは言うまでもない。 Although the outer frame case 17 is made of a metal material such as aluminum, it is needless to say that other materials such as a resin material may be used.
また、図１，図２の説明では低摩擦部材１８は衝撃緩衝部材１６Ｌ、１６Ｒ（あるいは１６Ｆ、１６Ｂ）がＨＤＤ１４の筐体と接触する面側に接着剤あるいは両面テープにより貼付するとしたが、図３（ａ）に示すように、衝撃緩衝部材１６Ｌ、１６Ｒ（あるいは１６Ｆ、１６Ｂ）が外枠ケース１７と接触する面側に貼付し、衝撃緩衝部材１６Ｌ、１６Ｒ（あるいは１６Ｆ、１６Ｂ）のＨＤＤ１４の筐体と接触する面側を接着剤等を用いて固着しても同様の効果が得られる。 In the description of FIGS. 1 and 2, the low friction member 18 is attached to the surface of the shock buffer members 16L and 16R (or 16F and 16B) in contact with the housing of the HDD 14 with an adhesive or a double-sided tape. As shown in FIG. 3 (a), the shock absorbing members 16L and 16R (or 16F and 16B) are attached to the surface contacting the outer frame case 17, and the shock absorbing members 16L and 16R (or 16F and 16B) of the HDD 14 are attached . similar effects can be obtained even when the surface side in contact with the housing and solid wear using an adhesive or the like.
さらに、衝撃緩衝部材１６Ｕ、１６ＤのＨＤＤ１４の筐体と接触する面側にも低摩擦部材１８を貼付するケース（図３（ｂ））、ＨＤＤ１４の筐体の左右に低摩擦部材１８を貼付するケース（図３（ｃ））、ＨＤＤ１４の筐体の上下左右前後に低摩擦部材１８を貼付するケース（図３（ｄ））、外枠ケース１７内面の上下左右前後の面に低摩擦部材１８を貼付するケース（図３（ｅ））等、衝撃緩衝部材１６、外枠ケース１７に対して様々な低摩擦部材１８の貼付配置の方法がある。但し、衝撃緩衝部材１６と低摩擦部材１８との接合面に対する反対面は接着剤あるいは両面テープにより必ず固着されているものとする。図３の（ｂ）、（ｄ）、（ｅ）図は上下左右前後全面からの衝撃を考慮したもので、図１の実施の形態および図３の（ａ）、（ｃ）は上下、つまりヘッドがディスク表面を叩く衝撃に対応したものである。 Further, a case (FIG. 3B) in which the low friction member 18 is also attached to the surface side of the shock absorbing member 16U, 16D that contacts the housing of the HDD 14 (FIG. 3B), and the low friction member 18 is attached to the left and right of the housing of the HDD 14. A case (FIG. 3C), a case (FIG. 3D) in which the low friction member 18 is attached to the top, bottom, left, and right front and back of the housing of the HDD 14 ; There are various methods of applying and arranging the low friction member 18 to the shock absorbing member 16 and the outer frame case 17, such as a case (FIG. 3E). However, the opposite surface against the joint surface between the shock absorbing member 16 and the low friction member 18 is assumed to be always fixed by adhesive or double-sided tape. 3 (b), (d), and (e) are considered in consideration of impacts from the upper, lower, left, and right front and rear, and the embodiment of FIG . 1 and FIGS. 3 (a) and 3 (c) are the upper and lower sides. This corresponds to the impact of the head hitting the disk surface.
また、前述の実施の形態では衝撃緩衝部材１６を１６Ｕ、１６Ｄ、１６Ｌ、１６Ｒ、１６Ｆ、１６Ｂの延べ１２個の個片で説明したが、図４のように衝撃緩衝部材により容器体１６−２Ｄと蓋体１６−２Ｕからなる収容体を形成し、容器体１６−２Ｄの内側面に低摩擦部材１８を貼付配置してもよい。この場合、外枠ケース１７は要、不要は問わない。 Further, the above-mentioned impact cushioning member 16 in the embodiment 16U, 16D, 16L, 16R, 16F, has been described in total 12 pieces of 16B, the container body 16-2D by shock absorbing member as shown in FIG. 4 And a lid 16-2U may be formed, and the low friction member 18 may be attached to the inner surface of the container body 16-2D. In this case, it does not matter whether the outer frame case 17 is necessary or unnecessary.
（実施の形態２）
図５は本発明の実施の形態２における衝撃緩衝装置を模式的に図示した断面図である。
(Embodiment 2)
FIG. 5 is a cross-sectional view schematically showing an impact shock absorber according to Embodiment 2 of the present invention.
図５（ａ）において１８−２はＨＤＤ１４に固着配置して図のように傾斜をもたせて成型した低摩擦部材である。低摩擦部材１８−２に対向する衝撃緩衝部材１６は低摩擦部材１８−２の傾斜に対応した角度で成型され、外枠ケース１７に固着されている。 In FIG. 5A, reference numeral 18-2 denotes a low-friction member fixedly arranged on the HDD 14 and molded with an inclination as shown in the figure. The shock absorbing member 16 facing the low friction member 18-2 is molded at an angle corresponding to the inclination of the low friction member 18-2, and is fixed to the outer frame case 17.
図５（ｂ）において１８−３も同様にＨＤＤ１４に固着配置して、図のように上下に対称に傾斜をもたせて成型した低摩擦部材である。 In FIG. 5 (b), 18-3 is also a low friction member which is fixedly attached to the HDD 14 and is formed with an inclination in the vertical direction as shown in the figure.
以上のように構成された衝撃緩衝装置について、以下その動作を説明する。 For shock shock absorber configured as above, the operation thereof will be described below.
図５（ａ）において、ＨＤＤ１４下面の衝撃緩衝部材１６Ｄの弾性復元力以外に、例えば衝撃緩衝部材１６Ｌの弾性復元力が図実線矢印のように低摩擦部材１８−２に対応する傾斜面を垂直に押す力となる。実線矢印の弾性復元力は紙面の上方向に押し上げる力（破線）と紙面の右方向に押す力（破線）に分解され、前者はＨＤＤ１４の下面の衝撃緩衝部材１６Ｄの弾性復元力に加算される。左右の衝撃緩衝部材１６Ｌ、１６Ｒの弾性復元力による押し上げ力の作用で衝撃を吸収したＨＤＤ１４の下面の衝撃緩衝部材１６Ｄは圧縮、変形後に速やかにその元の形状を回復し、次のＨＤＤに強い衝撃が加わる事態に備えることができる。 In FIG. 5A, in addition to the elastic restoring force of the shock absorbing member 16D on the lower surface of the HDD 14, for example, the elastic restoring force of the shock absorbing member 16L is perpendicular to the inclined surface corresponding to the low friction member 18-2 as indicated by the solid line arrow. It will be a force to push. Elastic restoring force of the solid line arrow is decomposed into a force (broken line) to press to the paper surface of the right direction and the force (broken line) to push upward in the drawing sheet, the former is added to the elastic restoring force of the lower surface of the shock absorbing member 16D of the HDD14 The Left and right shock absorbing members 16L, the lower surface of the shock absorbing member 16D of the HDD14 which has absorbed the shock effect of the upward force due to the elastic restoring force of the 16R is compressed, rapidly recovers its original shape after deformation, the next HDD It is possible to prepare for situations where a strong impact is applied.
下方向への落下時の衝撃力に対しては、図５（ａ）に示すように、左右の衝撃緩衝部材の傾斜面を垂直に押す力と傾斜面に沿った力に分解され、ＨＤＤ１４の下面の衝撃緩衝部材１６Ｄだけの場合よりも衝撃緩衝能力がさらに増加する。 For impact force when dropped downward, as shown in FIG. 5 (a), is decomposed into a force along the inclined surface and the force pushing the inclined surfaces of the right and left shock absorbing member vertically, the HDD14 The shock absorbing capacity is further increased as compared with the case of only the shock absorbing member 16D on the lower surface .
図５（ｂ）においては図５（ａ）に対して上下対称の構成となっているので、上下両方の圧縮、変形後の回復能力、上下両方の衝撃緩衝能力共により増すことができる。 In FIG. 5 (b), the configuration is symmetrical with respect to FIG. 5 (a), so that both the upper and lower compression, the recovery ability after deformation, and both the upper and lower impact buffering capacities can be increased.
本発明は、衝撃を吸収した衝撃緩衝部材が圧縮、変形後に速やかにその元の形状に回復し、衝撃緩衝部材の圧縮、変形状態が長く継続することによる材料の経年劣化を早める要因を取り除き、次のＨＤＤに強い衝撃が加わる事態に備えることができるといった優れた効果を有し、携帯型情報処理装置のハードディスクドライブの衝撃を緩衝する衝撃緩衝装置として有用である。 This onset Ming, shock absorbing member is compressed to absorb the shock, rapidly restored to its original shape after deformation, the compression of the shock absorbing member, the factors which accelerate the aging of materials due to the deformation state continues longer removed, has an excellent effect that can be provided in a situation where a strong impact is applied to the next HDD, it is useful as a shock buffering equipment you buffer the impact of the hard drive of a portable information processing apparatus .
