Description

本発明は、筐体に表示装置が収容され、筐体の内面に設けられた保持部に表示装置が保持された電子機器に関する。   The present invention relates to an electronic device in which a display device is housed in a housing and the display device is held in a holding portion provided on an inner surface of the housing.

電子機器は、通常、筐体に表示装置が収容されている。この電子機器として、落下等の衝撃から表示装置を保護するように構成されたものが知られている。
例えば、特許文献1には、表示パネルの下側と表示パネル用フレキシブルプリント配線基板の間に補強板を配置することにより、落下等により表示装置に衝撃が加わっても、表示パネルの破損を防止できることが記載されている(例えば、特許文献1)。
Electronic devices usually have a display device housed in a housing. As this electronic device, one configured to protect a display device from an impact such as dropping is known.
For example, Patent Document 1 discloses that a reinforcing plate is disposed between the lower side of the display panel and the flexible printed wiring board for the display panel, thereby preventing the display panel from being damaged even if an impact is applied to the display device due to dropping or the like.

特開2006−209037号公報(段落0007)JP 2006-209037 A (paragraph 0007)

ところで、近年では、電子機器は、筐体に対して表示装置の大画面化が求められている。
大画面化された表示装置は、大画面化に伴って、従来に比較して重量が増加するため、筐体が落下した際の衝撃を緩和するためには、接触片の湾曲半径を大きくする必要がある。
しかしながら、筐体の幅方向に沿った線を中心として湾曲する接触片は、湾曲半径を大きくすると、筐体の厚み寸法に影響を及ぼし、好ましくない。
Incidentally, in recent years, electronic devices are required to have a large display device with respect to a housing.
Since the display device with a larger screen increases in weight as compared with the conventional screen, the radius of the contact piece is increased in order to reduce the impact when the casing is dropped. There is a need.
However, a contact piece that is curved around a line along the width direction of the casing is not preferable if the bending radius is increased, which affects the thickness dimension of the casing.

本発明は、前述した課題を解決するためになされたものであり、その目的は、落下等の衝撃による表示装置の破損を防止できる電子機器を提供することにある。   The present invention has been made to solve the above-described problems, and an object thereof is to provide an electronic device that can prevent damage to a display device due to an impact such as dropping.

本発明の電子機器は、表示装置と、前記表示装置を収容する筐体と、前記筐体の内面に設けられ、前記表示装置を保持する保持部と、を備え、前記表示装置は、張り合わされた2枚のガラス基板と、前記2枚のガラス基板を保持するホルダとを含み、前記2枚のガラス基板のうちの一方のガラス基板が他方のガラス基板よりも突出した部分である1枚ガラス部と、前記2枚のガラス基板のどちらも他方のガラス基板から突出していない部分である2枚ガラス部とを有し、前記筐体の内面と前記表示装置の前記ホルダの前記1枚ガラス部側との間に空隙が設けられ、前記保持部は、前記表示装置の前記ホルダの前記2枚ガラス部側を保持する。   An electronic apparatus according to an aspect of the invention includes a display device, a housing that houses the display device, and a holding unit that is provided on an inner surface of the housing and holds the display device, and the display device is attached to the electronic device. A single glass that includes two glass substrates and a holder that holds the two glass substrates, and one of the two glass substrates is a portion protruding from the other glass substrate. And a single glass part of the housing of the housing and the holder of the display device, and a glass part that is a part of the two glass substrates that does not protrude from the other glass substrate. A gap is provided between the holder and the holding unit holds the two glass part side of the holder of the display device.

本発明においては、保持部を介して2枚ガラス部側を筐体の内面に固定するとともに、筐体の内面と1枚ガラス部側との間に空隙を設けたため、衝撃耐性が低い1枚ガラス部への、落下衝撃等の負荷軽減が可能となる。
さらに、落下等による衝撃緩和対策の追加の部品を必要とせず、部品点数の削減に貢献することが可能となる。
In the present invention, the two glass portions are fixed to the inner surface of the housing through the holding portion, and a gap is provided between the inner surface of the housing and the one glass portion, so that one sheet having low impact resistance is provided. It is possible to reduce a load such as a drop impact on the glass part.
Furthermore, it is possible to contribute to the reduction of the number of parts without requiring additional parts for mitigating impact caused by dropping or the like.

また、本発明の電子機器は、前記保持部は、第1係合部を有し、前記表示装置の前記ホルダは、前記2枚ガラス部側に第2係合部を有し、前記第1係合部および前記第2係合部が互いに係合することにより、前記保持部が前記表示装置を保持する。   In the electronic device according to the aspect of the invention, the holding portion may include a first engaging portion, and the holder of the display device may include a second engaging portion on the two glass portion side, When the engaging portion and the second engaging portion engage with each other, the holding portion holds the display device.

2枚ガラス部側の固定はホルダに設けた第2係合部と、保持部(筐体)に設けた第1係合部とを係合させることにより行うことができる。
これにより、ホルダに表示装置を取り付ける時に、第2係合部および第1係合部の係合により位置規制を行うことができるので組立作業が容易になる。
また、筐体にホルダを接着剤やテープで固定する場合に比べて分解が容易になる。
The two glass portions can be fixed by engaging the second engaging portion provided on the holder and the first engaging portion provided on the holding portion (housing).
Accordingly, when the display device is attached to the holder, the position can be regulated by the engagement of the second engagement portion and the first engagement portion, so that the assembling work is facilitated.
In addition, disassembly is easier than when the holder is fixed to the housing with an adhesive or tape.

さらに、本発明の電子機器は、前記第1係合部が前記筐体の長手方向に延び、かつ、前記筐体の幅方向に屈曲する溝状であるとともに、前記第2係合部が前記第1係合部に対応した略L字状である。   Furthermore, in the electronic device of the present invention, the first engagement portion extends in the longitudinal direction of the housing and has a groove shape that is bent in the width direction of the housing. It is substantially L-shaped corresponding to the first engaging portion.

よって、第1係合部および第2係合部を筐体の厚み方向に延ばす必要がない。
これにより、筐体が薄型の場合でも第1係合部および第2係合部の長さを確保可能であり、第1係合部および第2係合部の柔軟性を確保できる。
Therefore, it is not necessary to extend the first engaging portion and the second engaging portion in the thickness direction of the housing.
Thereby, even when the casing is thin, the lengths of the first engaging portion and the second engaging portion can be ensured, and the flexibility of the first engaging portion and the second engaging portion can be ensured.

また、本発明の電子機器は、前記ホルダの外側端面と、前記筐体の内面との間に空隙が設けられている。
このように、ホルダの外側端面と筐体の内面との間に空隙を設けることにより1枚ガラス部側に伝わる衝撃を緩和できる。
In the electronic device of the present invention, a gap is provided between the outer end surface of the holder and the inner surface of the housing.
Thus, the impact transmitted to the one glass part side can be relieved by providing a space | gap between the outer side end surface of a holder, and the inner surface of a housing | casing.

さらに、本発明の電子機器は、前記ホルダにおける前記1枚ガラス部側の外側端面と、前記筐体の内面との間に空隙が設けられているとともに、前記ホルダにおける前記1枚ガラス部側の外側端面と、前記筐体の内面とのうちの一方に設けられて他方に向かう緩衝リブを有する。   Furthermore, in the electronic device of the present invention, a gap is provided between the outer end surface of the holder on the side of the single glass portion and the inner surface of the housing, and the electronic device on the side of the single glass portion of the holder is provided. A buffer rib is provided on one of the outer end surface and the inner surface of the housing and faces the other.

1枚ガラス部側に空隙を設け、空隙に緩衝リブを備えた。よって、例えば、筐体に極端に大きな衝撃が生じた場合に、1枚ガラス部側にも緩衝リブを経て衝撃を分散させることができる。
これにより、1枚ガラス部側に衝撃が集中することを防いで、1枚ガラス部側の破損を防止できる。
A gap was provided on one glass part side, and buffer ribs were provided in the gap. Therefore, for example, when an extremely large impact is generated in the housing, the impact can be dispersed also through the buffer ribs on the single glass portion side.
Thereby, it can prevent that an impact concentrates on the single glass part side, and can prevent the damage on the single glass part side.

また、本発明の電子機器は、前記筐体の長手方向に沿った前記第1係合部における壁部の断面積よりも前記第2係合部における前記壁部に当接するリブの断面積が大きく、かつ、前記筐体の厚み方向に沿った前記壁部の断面積が前記リブの断面積よりも大きい。   Further, in the electronic device of the present invention, the cross-sectional area of the rib contacting the wall portion in the second engaging portion is larger than the cross-sectional area of the wall portion in the first engaging portion along the longitudinal direction of the housing. It is large and the cross-sectional area of the said wall part along the thickness direction of the said housing | casing is larger than the cross-sectional area of the said rib.

一般的に、表示装置のホルダに筐体よりも柔軟性の高い樹脂を使用するので、衝撃をホルダ側の第2係合部(リブ)に衝撃を集中させる方がリブの破損を抑えられる。
そこで、筐体の長手方向に沿った第1係合部における壁部の断面積よりも第2係合部における壁部に当接するリブの断面積を大きくすることにより、ホルダ側の第2係合部に衝撃を集中させることができる。
Generally, since a resin having higher flexibility than the housing is used for the holder of the display device, damage to the rib can be suppressed by concentrating the impact on the second engaging portion (rib) on the holder side.
Therefore, the second engagement on the holder side is made larger by making the cross-sectional area of the rib contacting the wall portion in the second engagement portion larger than the cross-sectional area of the wall portion in the first engagement portion along the longitudinal direction of the housing. Impact can be concentrated at the joint.

加えて、筐体の厚み方向に沿った壁部の断面積をリブの断面積よりも大きくすることにより、厚みに差を設けてホルダ側の第2係合部を撓み易くさせることができる。
このように、ホルダ側のリブに衝撃を集中させ、かつ、ホルダ側のリブを撓み易くすることにより、ホルダ側のリブに伝わった衝撃を表示装置に伝わる前に吸収し易くできる。
In addition, by making the cross-sectional area of the wall portion along the thickness direction of the housing larger than the cross-sectional area of the rib, it is possible to make the second engaging portion on the holder side easy to bend by providing a difference in thickness.
Thus, by concentrating the impact on the holder-side rib and making the holder-side rib easy to bend, the impact transmitted to the holder-side rib can be easily absorbed before being transmitted to the display device.

また、本発明の電子機器は、前記1枚ガラス部に表示装置用フレキシブルプリント配線基板が接続された。
本発明においては、1枚ガラス部に表示装置用フレキシブルプリント配線基板が接続されているため、1枚ガラス部だけではなく、表示装置用フレキシブルプリント配線基板も保護できる。
In the electronic apparatus of the present invention, a flexible printed wiring board for a display device is connected to the single glass part.
In the present invention, since the flexible printed wiring board for display device is connected to the single glass portion, not only the single glass portion but also the flexible printed wiring substrate for display device can be protected.

本発明の電子機器によれば、フレキシブルプリント配線基板が接続される1枚ガラス部の反対側を筐体に固定し、収容部と1枚ガラス部側との間に空隙を設けることにより、落下等の衝撃による表示装置の破損を防止できる。   According to the electronic device of the present invention, the opposite side of the single glass part to which the flexible printed wiring board is connected is fixed to the housing, and a gap is provided between the housing part and the single glass part side, thereby dropping It is possible to prevent damage to the display device due to impact such as.

図11に示すように、ケース21の内側に収容部24が設けられ、収容部24の内面24Aに保持部28が設けられている。
保持部28は、第2係合部48に係合可能に対応した一対の第1係合部46を有する。
As shown in FIG. 11, the accommodating portion 24 is provided inside the case 21, and the holding portion 28 is provided on the inner surface 24 </ b> A of the accommodating portion 24.
The holding portion 28 has a pair of first engaging portions 46 corresponding to the second engaging portions 48 so as to be engageable.

図12に示すように、第1係合部46は、ケース21の長手方向(矢印A方向)に延び、かつ、ケースの幅方向(矢印B方向)に屈曲させることにより、第2係合部48(図6、図9参照)に対応させて略L字形溝状に形成された係合溝である。
図6に示すように、第1係合部46が第2係合部48に対応させて略L字状に形成されることにより、第1係合部46に第2係合部48が係合される。
As shown in FIG. 12, the first engagement portion 46 extends in the longitudinal direction (arrow A direction) of the case 21 and is bent in the width direction (arrow B direction) of the case 21 to thereby form the second engagement portion. 48 (refer to FIG. 6 and FIG. 9) is an engagement groove formed in a substantially L-shaped groove shape.
As shown in FIG. 6, the first engagement portion 46 is formed in a substantially L shape corresponding to the second engagement portion 48, so that the second engagement portion 48 is engaged with the first engagement portion 46. Combined.

図5に示すように、一対の第1係合部46に一対の第2係合部48が各々係合されることにより、ホルダ35の2枚ガラス部38側が保持部28に保持される。
ホルダ35の2枚ガラス部38側が保持部28に保持されることにより、表示装置26が保持部28に保持される。
すなわち、保持部28は、表示装置26のホルダ35の2枚ガラス部38側を保持する部位である。
As shown in FIG. 5, the pair of second engaging portions 48 are engaged with the pair of first engaging portions 46, whereby the two glass portions 38 of the holder 35 are held by the holding portion 28.
The display device 26 is held by the holding portion 28 by holding the two glass portions 38 of the holder 35 to the holding portion 28.
That is, the holding part 28 is a part that holds the two glass part 38 side of the holder 35 of the display device 26.

このように、一対の第2係合部48を一対の第1係合部46に各々係合させることにより、ホルダ35の2枚ガラス部38側を保持部28に保持できる。
これにより、筐体12に表示装置26を取り付ける時に、一対の第2係合部48および一対の第1係合部46の係合により位置規制を行うことができるので組立作業が容易になる。
また、保持部28にホルダ35を接着剤やテープで固定する場合に比べて分解が容易になる。
Thus, the two glass part 38 side of the holder 35 can be hold | maintained in the holding | maintenance part 28 by engaging a pair of 2nd engaging part 48 with a pair of 1st engaging part 46, respectively.
Thus, when the display device 26 is attached to the housing 12, the position can be regulated by the engagement of the pair of second engaging portions 48 and the pair of first engaging portions 46, so that the assembling work is facilitated.
In addition, disassembly is easier than in the case where the holder 35 is fixed to the holding portion 28 with an adhesive or tape.

さらに、図12に示すように、第1係合部46がケース21の長手方向(矢印A方向)に延出され、かつ、ケース21の幅方向(矢印B方向)に屈曲する溝状に形成されている。
さらに、図9に示すように、第1係合部46に対応させて第2係合部48が略L字状に形成されている。
Further, as shown in FIG. 12, the first engaging portion 46 is formed in a groove shape extending in the longitudinal direction (arrow A direction) of the case 21 and bending in the width direction (arrow B direction) of the case 21. Has been.
Furthermore, as shown in FIG. 9, a second engagement portion 48 is formed in a substantially L shape so as to correspond to the first engagement portion 46.

よって、第1係合部46および第2係合部48を、ケース21の厚み方向(矢印C方向)に延ばす必要がない。
これにより、ケース21が薄型の場合でも第1係合部46および第2係合部48を略L字状に形成して、第1係合部46および第2係合部48の長さL1を確保して第1係合部46および第2係合部48の柔軟性を確保できる。
Therefore, it is not necessary to extend the first engagement portion 46 and the second engagement portion 48 in the thickness direction (arrow C direction) of the case 21.
Thereby, even when the case 21 is thin, the first engagement portion 46 and the second engagement portion 48 are formed in a substantially L shape, and the length L1 of the first engagement portion 46 and the second engagement portion 48 is formed. And the flexibility of the first engaging portion 46 and the second engaging portion 48 can be ensured.

これに対して、図13に示す比較例のように、第2係合部51を、ケースの厚み方向(矢印C方向)に延ばして長さL2を確保するためには、ケースを薄型に保つことが難しい。   On the other hand, as in the comparative example shown in FIG. 13, in order to secure the length L2 by extending the second engaging portion 51 in the thickness direction (arrow C direction) of the case, the case is kept thin. It is difficult.

ここで、図14に示すように、ケース21の長手方向(矢印A方向)に沿った第1係合部46における壁部46Aの壁部幅寸法(断面積)はW1である。
また、第2係合部48における壁部46Aに当接する折曲リブ(リブ)48Bのリブ幅寸法(断面積)はW2である。
第2係合部48のリブ幅寸法W2は第1係合部46の壁部幅寸法W1より大きい。
Here, as shown in FIG. 14, the wall portion width dimension (cross-sectional area) of the wall portion 46A in the first engagement portion 46 along the longitudinal direction (arrow A direction) of the case 21 is W1.
In addition, the rib width dimension (cross-sectional area) of the bent rib (rib) 48B that contacts the wall portion 46A in the second engagement portion 48 is W2.
The rib width dimension W2 of the second engagement portion 48 is larger than the wall width dimension W1 of the first engagement portion 46.

また、図15に示すように、ケース21の厚み方向に沿った第1係合部46における壁部46Aの壁部厚み寸法(断面積)はW3である。
また、第2係合部48における壁部46Aに当接する折曲リブ48Bのリブ厚み寸法(断面積)はW4である。
第1係合部46の壁部厚み寸法W3は第2係合部48のリブ厚み寸法W4より大きい。
As shown in FIG. 15, the wall thickness dimension (cross-sectional area) of the wall 46A in the first engagement portion 46 along the thickness direction of the case 21 is W3.
The rib thickness dimension (cross-sectional area) of the bent rib 48B that contacts the wall portion 46A of the second engagement portion 48 is W4.
The wall thickness dimension W3 of the first engagement portion 46 is larger than the rib thickness dimension W4 of the second engagement portion 48.

ここで、一般的に、表示装置のホルダ35にケース21よりも柔軟性の高い樹脂が使用されるので、衝撃をホルダ35側の第2係合部48に衝撃を集中させる方が第2係合部48の破損を抑えられる。
そこで、第2係合部48のリブ幅寸法W2を第1係合部46の壁部幅寸法W1より大きくした。よって、ホルダ35側の第2係合部48に衝撃を集中させることができる。
Here, since a resin having higher flexibility than that of the case 21 is generally used for the holder 35 of the display device, it is more likely that the impact is concentrated on the second engaging portion 48 on the holder 35 side. The breakage of the joint portion 48 can be suppressed.
Therefore, the rib width dimension W2 of the second engagement portion 48 is made larger than the wall width dimension W1 of the first engagement portion 46. Therefore, the impact can be concentrated on the second engagement portion 48 on the holder 35 side.

加えて、第1係合部46の壁部厚み寸法W3を第2係合部48のリブ厚み寸法W4より大きくした。よって、厚みに差を設けて第2係合部48を撓み易くさせることができる。
このように、第2係合部48に衝撃を集中させ、かつ、第2係合部48を撓み易くすることにより、第2係合部48を弾性変形させることができる(図16参照)。
In addition, the wall thickness dimension W3 of the first engagement portion 46 is made larger than the rib thickness dimension W4 of the second engagement portion 48. Therefore, the second engagement portion 48 can be easily bent by providing a difference in thickness.
Thus, the second engaging portion 48 can be elastically deformed by concentrating the impact on the second engaging portion 48 and making the second engaging portion 48 flexible (see FIG. 16).

図16に示すように、電子機器10が矢印方向に落下した場合に、第2係合部48を弾性変形させて、第2係合部48に伝わった衝撃を表示装置26に伝わる前に吸収し易くできる。
ここで、図16においては、第2係合部48の弾性変形による衝撃吸収の例を理解し易くするために第2係合部48の弾性変形状態を実変形より大きく表示した。
As shown in FIG. 16, when the electronic device 10 falls in the direction of the arrow, the second engagement portion 48 is elastically deformed, and the impact transmitted to the second engagement portion 48 is absorbed before being transmitted to the display device 26. Easy to do.
Here, in FIG. 16, the elastic deformation state of the second engagement portion 48 is displayed larger than the actual deformation in order to facilitate understanding of an example of shock absorption due to the elastic deformation of the second engagement portion 48.

以上説明したように、電子機器10によれば、表示装置26用のフレキシブルプリント配線基板36が接続される1枚ガラス部37の反対側、すなわち、保持部28を介して2枚ガラス部38側を保持するホルダ35を収容部24に固定した。
さらに、収容部24の内面24Aとホルダ35の1枚ガラス部37側(外側端面35B)との間に空隙42を設けた。
As described above, according to the electronic device 10, the opposite side of the single glass part 37 to which the flexible printed wiring board 36 for the display device 26 is connected, that is, the two glass part 38 side through the holding part 28. The holder 35 that holds the lens is fixed to the accommodating portion 24.
Further, a gap 42 was provided between the inner surface 24 </ b> A of the accommodating portion 24 and the single glass portion 37 side (outer end surface 35 </ b> B) of the holder 35.

このように、2枚ガラス部38側でホルダ35を収容部24に固定し、1枚ガラス部37側では固定しないことにより、電子機器10が落下した場合に、表示装置26の衝撃耐性の低い1枚ガラス部37への落下衝撃等の負荷軽減が可能となる。
さらに、電子機器10の落下等による衝撃緩和対策部品を必要とせず、部品点数の削減に貢献することが可能となる。
As described above, the holder 35 is fixed to the housing portion 24 on the two-glass portion 38 side and is not fixed on the one-glass portion 37 side, so that the impact resistance of the display device 26 is low when the electronic device 10 is dropped. It is possible to reduce a load such as a drop impact on the single glass portion 37.
Furthermore, it is possible to contribute to the reduction of the number of parts without requiring shock mitigation countermeasure parts due to dropping of the electronic device 10 or the like.
