Description

本発明は、携帯電話機、スマートフォン等の携帯電子機器に関する。   The present invention relates to a mobile electronic device such as a mobile phone and a smartphone.

従来から、液晶モジュール等で構成される表示部を備えた携帯電子機器が知られている。例えば、特許文献１に示される携帯電話機の表示部は、筐体内に配される液晶モジュールと、該液晶モジュールの表示領域側を覆う透光性の表示パネルとを備えており、筐体の外部から、表示パネルを介して液晶モジュールの表示を視認するように構成されている。   2. Description of the Related Art Conventionally, portable electronic devices including a display unit configured with a liquid crystal module or the like are known. For example, a display unit of a mobile phone disclosed in Patent Document 1 includes a liquid crystal module arranged in a housing and a translucent display panel that covers the display area side of the liquid crystal module, and is provided outside the housing. The display of the liquid crystal module is visually recognized through the display panel.

表示パネルは、通常、筐体の周縁に対して接着されている。接着方法としては、両面テープによる方法や、接着剤による方法が広く用いられており、例えば、特許文献１では、熱活性接着剤を含有する両面テープを用いて、表示パネルを筐体に接着している。   The display panel is usually bonded to the periphery of the housing. As a bonding method, a method using a double-sided tape or a method using an adhesive is widely used. For example, in Patent Document 1, a display panel is bonded to a casing using a double-sided tape containing a heat-active adhesive. ing.

図１０は、参考例に係る携帯電子機器の表示パネル接着部分を示す図であり、（ａ）は、参考例に係る携帯電子機器の側部における表示パネル接着部分を示す断面図、（ｂ）は、参考例に係る携帯電子機器の上部における表示パネル接着部分を示す断面図である。   10A and 10B are diagrams showing a display panel adhesion portion of a portable electronic device according to a reference example. FIG. 10A is a cross-sectional view showing a display panel adhesion portion in a side portion of the portable electronic device according to the reference example. These are sectional drawings which show the display panel adhesion | attachment part in the upper part of the portable electronic device which concerns on a reference example.

一方、接着剤を用いて表示パネル１０１を筐体１０２に接着する場合は、図１０に示すように、筐体１０２の周縁に接着剤塗布面１０３を設け、ここに接着剤を塗布した後、筐体１０２に表示パネル１０１を重ね合わせる。このとき、表示パネル１０１で押圧された接着剤が、筐体１０２と表示パネル１０１との隙間から筐体外側にはみ出し、外観を低下させることがあった。特に、接着剤の塗布工程における始点と終点は、防水性を確保するために、必ずつながるように塗布する必要があるので、接着剤の塗布量が部分的に多くなり、筐体外側へのはみ出しが生じ易いという問題があった。   On the other hand, when the display panel 101 is bonded to the housing 102 using an adhesive, an adhesive application surface 103 is provided on the periphery of the housing 102 as shown in FIG. The display panel 101 is overlaid on the housing 102. At this time, the adhesive pressed by the display panel 101 sometimes protrudes from the gap between the casing 102 and the display panel 101 to the outside of the casing, thereby reducing the appearance. In particular, the start and end points in the adhesive application process must be applied so as to be connected to ensure waterproofness, so the amount of adhesive applied partially increases and protrudes outside the housing. There was a problem that it was easy to occur.

そこで、図１０に示す参考例では、筐体１０２の接着剤塗布面１０３に、筐体内側に向かって低くなる斜面を構成するとともに、接着剤塗布面１０３の筐体内側に、急激に立ち下がる絶壁１０４や溝１０５を設けることにより、表示パネル１０１で押圧された接着剤を筐体内側に導き、筐体外側へのはみ出しを防止している。   Therefore, in the reference example illustrated in FIG. 10, the adhesive coating surface 103 of the housing 102 has a slope that decreases toward the inside of the housing, and falls sharply inside the housing of the adhesive coating surface 103. By providing the precipitous wall 104 and the groove 105, the adhesive pressed by the display panel 101 is guided to the inside of the housing, and the protrusion to the outside of the housing is prevented.

しかしながら、図１０に示すような絶壁１０４や溝１０５を設けると、筐体１０２において肉厚が薄くなる部分が発生し、部位によっては必要強度が満足できなくなる可能性がある。   However, when the precipice 104 and the groove 105 as shown in FIG. 10 are provided, a portion where the thickness is reduced occurs in the housing 102, and the required strength may not be satisfied depending on the portion.

例えば、イヤホンプラグ、ＵＳＢプラグ、ＳＩＭカードなどの挿脱手段が挿脱されるコネクタ部を備えた携帯電子機器では、コネクタ部を露出させるために筐体に開口部を有しており、挿脱手段の挿脱に際しては、筐体の開口部近傍に大きな挿脱操作力が作用するので、強度不足が発生する可能性があった。   For example, in a portable electronic device having a connector portion into which an insertion / removal means such as an earphone plug, a USB plug, and a SIM card is inserted and removed, the housing has an opening to expose the connector portion. When inserting / removing the means, a large insertion / removal operation force acts in the vicinity of the opening of the housing, which may cause insufficient strength.

本発明は上記した課題を解決するためになされたものであり、表示パネルを接着剤で筐体に接着するものでありながら、接着剤の筐体外側へのはみ出しを防止しつつ、挿脱手段の挿脱操作力が作用する開口部近傍の強度を増加させる携帯電子機器の提供を目的とする。   The present invention has been made in order to solve the above-described problem, and while inserting the display panel to the housing with an adhesive, the insertion / removal means while preventing the adhesive from protruding to the outside of the housing An object of the present invention is to provide a portable electronic device that increases the strength in the vicinity of the opening where the insertion / removal operation force acts.

この図に示すように、筐体２の上面には、イヤホンプラグ（挿脱手段）を挿脱するための開口部１０ａが形成されている。つまり、筐体２の内部には、イヤホンプラグが挿脱されるイヤホンジャック（コネクタ部）が設けられており、該イヤホンジャックの挿脱口が開口部１０ａを介して露出されるようになっている。   As shown in this figure, an opening 10a for inserting / removing an earphone plug (insertion / removal means) is formed on the upper surface of the housing 2. That is, the housing 2 is provided with an earphone jack (connector portion) into which the earphone plug is inserted and removed, and the insertion / removal port of the earphone jack is exposed through the opening 10a. .

図３は、本発明の第１実施形態に係る携帯電子機器の第１筐体を示す斜視図である。   FIG. 3 is a perspective view showing a first housing of the portable electronic device according to the first embodiment of the present invention.

図１〜図３に示すように、筐体２は、携帯電子機器１Ａの前面を構成する第１筐体１０と、携帯電子機器１Ａの後面を構成する第２筐体１１とを備え、基板は、第１筐体１０と第２筐体１１で覆われる。   As shown in FIGS. 1 to 3, the housing 2 includes a first housing 10 that forms the front surface of the mobile electronic device 1 </ b> A, and a second housing 11 that forms the rear surface of the mobile electronic device 1 </ b> A. Is covered with the first housing 10 and the second housing 11.

図３に示すように、第１筐体１０の前面は、液晶モジュール５（図６参照）を収容するための凹部１０ｂと、押しボタン９を収容するために、凹部１０ｂの下側に複数形成される開口部１０ｃと、筐体２の内部に配置される光センサ１２、ストロボ１３、レシーバ１４およびカメラ１５（図６〜図９参照）の前方を開放するために、凹部１０ｂの上側にそれぞれ形成される開口部１０ｄ、１０ｅ、１０ｆ、１０ｇとを備えている。また、第１筐体１０の上面は、前述したイヤホンプラグ挿脱用の開口部１０ａを備えており、その位置は、光センサ１２に対応する開口部１０ｄの近傍である。   As shown in FIG. 3, a plurality of front surfaces of the first housing 10 are formed below the recess 10 b for storing the recess 10 b for storing the liquid crystal module 5 (see FIG. 6) and the push button 9. And 10 c above the recess 10 b to open the front of the optical sensor 12, strobe 13, receiver 14, and camera 15 (see FIGS. 6 to 9) disposed inside the housing 2. The openings 10d, 10e, 10f, and 10g are formed. Further, the upper surface of the first housing 10 is provided with the above-described opening 10 a for inserting and removing the earphone plug, and the position thereof is in the vicinity of the opening 10 d corresponding to the optical sensor 12.

図４は、図３の要部拡大斜視図である。   FIG. 4 is an enlarged perspective view of a main part of FIG.

図３および図４に示すように、第１筐体１０の周縁部には、表示パネル６を接着する接着剤を塗布するための第１塗布領域１０ｈが設けられている。つまり、表示パネル６を第１筐体１０に接着する工程では、第１筐体１０の第１塗布領域１０ｈに接着剤を塗布した後、第１筐体１０に表示パネル６を重ね合わせる。このとき、表示パネル６で押圧された接着剤が、第１筐体１０と表示パネル６との隙間から筐体外側にはみ出すと、外観を低下させることになる。特に、接着剤の塗布工程における始点と終点は、防水性を確保するために、必ずつながるように塗布する必要があるので、接着剤の塗布量が部分的に多くなり、筐体外側へのはみ出しが生じ易い。   As shown in FIG. 3 and FIG. 4, a first application region 10 h for applying an adhesive that adheres the display panel 6 is provided on the peripheral portion of the first housing 10. That is, in the step of bonding the display panel 6 to the first housing 10, the adhesive is applied to the first application region 10 h of the first housing 10, and then the display panel 6 is superimposed on the first housing 10. At this time, when the adhesive pressed by the display panel 6 protrudes from the gap between the first housing 10 and the display panel 6 to the outside of the housing, the appearance is deteriorated. In particular, the start and end points in the adhesive application process must be applied so as to be connected to ensure waterproofness, so the amount of adhesive applied partially increases and protrudes outside the housing. Is likely to occur.

本実施形態の第１筐体１０は、第１塗布領域１０ｈに塗布された接着剤のはみ出しを防止するために、図１０に示す参考例と同様のはみ出し防止構造を備える。以下、本実施形態のはみ出し防止構造を図１０（本実施形態の符号は括弧書きとする）を参照して説明する。   In order to prevent the adhesive applied to the first application region 10h from protruding, the first housing 10 of the present embodiment includes a protrusion preventing structure similar to the reference example shown in FIG. Hereinafter, the protrusion preventing structure of the present embodiment will be described with reference to FIG. 10 (the reference numerals of the present embodiment are parenthesized).

本実施形態の第１筐体１０は、第１塗布領域１０ｈのうち、凹部１０ｂの周縁部に沿う部分（表示パネル６の側縁部および下縁部を接着する部分）では、図１０の（ａ）に示す構造を備え、凹部１０ｂの周縁部に沿わない部分（表示パネル６の上縁部を接着する部分）では、図１０の（ｂ）に示す構造を備える。   In the first casing 10 of the present embodiment, a portion of the first application region 10h along the peripheral portion of the recess 10b (a portion where the side edge portion and the lower edge portion of the display panel 6 are bonded) is shown in FIG. The part shown in FIG. 10B has the structure shown in FIG. 10B. The part shown in FIG. 10B has the structure shown in a) and does not follow the peripheral edge of the recess 10b.

図１０の（ａ）、（ｂ）に示すように、第１筐体１０の周縁部には、表示パネル６を位置決めする面１０ｉが形成されており、その内側の一段下がった位置に第１塗布領域１０ｈとなる接着剤塗布面１０ｊが形成されている。接着剤塗布面１０ｊは、筐体内側に向かって低くなる斜面となっており、接着剤塗布面１０ｊの筐体内側には、急激に立ち下がる絶壁１０ｋや溝１０ｍが設けられる。これにより、表示パネル６で押圧された接着剤を筐体内側に導き、筐体外側へのはみ出しを防止している。接着剤塗布面１０ｊは、第１筐体１０の周縁を囲むように環状となっている。   As shown in FIGS. 10A and 10B, a surface 10 i for positioning the display panel 6 is formed on the peripheral portion of the first housing 10, and the first lower position is located on the inner side. An adhesive application surface 10j to be an application region 10h is formed. The adhesive application surface 10j is a slope that becomes lower toward the inside of the housing, and a steep precipitating wall 10k and a groove 10m are provided inside the housing of the adhesive application surface 10j. As a result, the adhesive pressed by the display panel 6 is guided to the inside of the casing, and the protrusion to the outside of the casing is prevented. The adhesive application surface 10j has an annular shape so as to surround the periphery of the first housing 10.

しかしながら、絶壁１０ｋや溝１０ｍは、第１筐体１０において肉厚が薄くなる部分を発生させ、部位によっては必要強度が満足できなくなる可能性があり、本実施形態の第１筐体１０では、イヤホンプラグの挿脱に際して大きな挿脱操作力が作用する可能性がある開口部１０ａの近傍部位がこれに相当する。   However, the precipice 10k and the groove 10m generate a portion where the thickness is reduced in the first housing 10, and depending on the portion, there is a possibility that the required strength may not be satisfied. In the first housing 10 of the present embodiment, This corresponds to the vicinity of the opening 10a where a large insertion / removal operation force may be applied when the earphone plug is inserted / removed.

図５は、図４のＡ−Ａ断面図である。   5 is a cross-sectional view taken along the line AA in FIG.

図４および図５に示すように、第１筐体１０には、接着剤と表示パネル６との接着面積を大きくする領域１０ｎが第１塗布領域１０ｈの開口部１０ａ近傍に形成されている。例えば、本実施形態の第１筐体１０では、開口部１０ａ近傍における接着剤塗布面１０ｊの内側に、絶壁１０ｋや溝１０ｍを設けず、接着剤塗布面１０ｊに連続する斜面（接着剤塗布面１０ｊと逆向きの緩やかな斜面）を形成し、この斜面を領域１０ｎとしている。なお、本実施形態でいう「接着面積」とは、環状の接着剤塗布面１０ｊの周方向において単位長さあたりの接着面積をいい、「接着面積が大きくする」とは、単位長さあたりの接着面積が他の部位に比し大きいことをいう。   As shown in FIGS. 4 and 5, the first housing 10 is formed with a region 10 n that increases the adhesive area between the adhesive and the display panel 6 in the vicinity of the opening 10 a of the first application region 10 h. For example, in the first housing 10 of the present embodiment, a slope (adhesive application surface) that is continuous with the adhesive application surface 10j without providing the precipice 10k or the groove 10m inside the adhesive application surface 10j in the vicinity of the opening 10a. 10j is formed as a region 10n. The “adhesion area” in the present embodiment refers to the adhesion area per unit length in the circumferential direction of the annular adhesive application surface 10j, and “increase the adhesion area” refers to the per unit length. It means that the adhesion area is larger than other parts.

このような領域１０ｎを第１筐体１０に設けると、第１塗布領域１０ｈの全域では、接着剤の筐体外側へのはみ出しを防止しながらも、イヤホンプラグの挿脱操作力が作用する開口部１０ａ近傍では、表示パネル６との接着面積を大きくしたり、絶壁１０ｋや溝１０ｍを設けずに肉厚を確保することにより、強度を増加させることが可能になる。   When such a region 10n is provided in the first casing 10, an opening in which the earphone plug insertion / removal operation force acts on the entire first application region 10h while preventing the adhesive from protruding to the outside of the casing. In the vicinity of the portion 10a, the strength can be increased by increasing the adhesion area with the display panel 6 or securing the thickness without providing the precipice 10k and the groove 10m.

また、本実施形態では、第１塗布領域に接着剤を塗布する際に、その始点および終点となる位置に領域１０ｎを形成している。つまり、接着剤の塗布工程における始点と終点は、防水性を確保するために、必ずつながるように塗布する必要があるため、接着剤の塗布量が部分的に多くなり、筐体外側へのはみ出しが生じ易いのであるが、多く塗布された接着剤を領域１０ｎに導くことにより、接着剤の筐体外側へのはみ出しを防止しつつ、開口部１０ａ近傍における表示パネル６との接着面積を大きくすることができる。
［第２実施形態］
つぎに、本発明の第２実施形態に係る携帯電子機器について、図６〜図９を参照して説明する。ただし、第１実施形態と共通する部分は、第１実施形態と同じ符号を用いることにより、第１実施形態の説明を援用する。 Moreover, in this embodiment, when apply | coating an adhesive agent to a 1st application area | region, the area | region 10n is formed in the position used as the starting point and an end point. In other words, the start and end points in the adhesive application process must be applied so that they are always connected to ensure waterproofness, so the amount of adhesive applied partially increases and protrudes outside the housing. However, by guiding a large amount of applied adhesive to the region 10n, the adhesive area with the display panel 6 in the vicinity of the opening 10a is increased while preventing the adhesive from protruding to the outside of the housing. be able to.
[Second Embodiment]
Next, a portable electronic device according to a second embodiment of the present invention will be described with reference to FIGS. However, the part which is common with 1st Embodiment uses the same code | symbol as 1st Embodiment, and uses description of 1st Embodiment.

この図に示すように、第２実施形態に係る携帯電子機器１Ｂは、表示パネル６を接着する接着剤が塗布される領域として、第１筐体１０の前面に第２塗布領域１０ｐを備える点が前記第１実施形態と相違している。   As shown in this figure, the portable electronic device 1B according to the second embodiment includes a second application region 10p on the front surface of the first housing 10 as a region to which an adhesive that adheres the display panel 6 is applied. Is different from the first embodiment.

図７は、図６の要部拡大斜視図である。   FIG. 7 is an enlarged perspective view of a main part of FIG.

この図に示すように、第２塗布領域１０ｐは、光センサ１２を囲うように形成される。具体的には、光センサ１２の前方を開放するために第１筐体１０に形成された開口部１０ｄを囲うように第１筐体１０の前面に第２塗布領域１０ｐが形成されている。この開口部１０ｄは、前方が表示パネル６で覆われるため、本来、開口部１０ｄの周囲には防水用の接着が不要であるが、敢えて開口部１０ｄの周囲に第２塗布領域１０ｐを形成している。なお、開口部１０ｄの開口の周囲と第２塗布領域１０ｐの間には、第２塗布領域１０ｐに塗布される接着剤が開口部１０ｄの開口へ流れ込むのを規制するリブ１０ｑが立設されている。   As shown in this figure, the second application region 10 p is formed so as to surround the optical sensor 12. Specifically, a second application region 10p is formed on the front surface of the first housing 10 so as to surround an opening 10d formed in the first housing 10 in order to open the front of the optical sensor 12. Since the front of the opening 10d is covered with the display panel 6, waterproofing is not necessary around the opening 10d, but the second application region 10p is intentionally formed around the opening 10d. ing. A rib 10q is provided between the periphery of the opening of the opening 10d and the second application region 10p so as to restrict the adhesive applied to the second application region 10p from flowing into the opening of the opening 10d. Yes.

このような第２塗布領域１０ｐによれば、第１筐体１０における表示パネル６との接着面積を増加させるので、第１筐体１０の強度を高めることができる。特に、本実施形態の第２塗布領域１０ｐは、イヤホンプラグの挿脱操作力が作用する開口部１０ａ近傍に形成されるので、第１実施形態の領域１０ｎと同様に、開口部１０ａの近傍部位において第１筐体１０の強度が高められるという効果を奏する。なお、第２実施形態では、第１実施形態の領域１０ｎに代えて第２塗布領域１０ｐを備えるが、両方の領域１０ｎ、１０ｐを備えるようにしてもよい。   According to such 2nd application | coating area | region 10p, since the adhesion area with the display panel 6 in the 1st housing | casing 10 is increased, the intensity | strength of the 1st housing | casing 10 can be raised. In particular, since the second application region 10p of the present embodiment is formed in the vicinity of the opening 10a where the insertion / removal operation force of the earphone plug acts, the vicinity of the opening 10a is similar to the region 10n of the first embodiment. In this case, the strength of the first housing 10 is increased. In the second embodiment, the second application region 10p is provided instead of the region 10n of the first embodiment, but both regions 10n and 10p may be provided.

第２塗布領域１０ｐに対する接着剤の塗布は、第１塗布領域１０ｈに対する接着剤の塗布と別の工程で行なうことも可能であるが、第１塗布領域１０ｈに対する接着剤の塗布と同じ工程で行なうことが好ましい。例えば、本実施形態の第２塗布領域１０ｐは、第１塗布領域１０ｈと連続しており、第１塗布領域１０ｈと同じ工程で接着剤を一筆書き状に塗布することができる。   The application of the adhesive to the second application area 10p can be performed in a separate process from the application of the adhesive to the first application area 10h, but is performed in the same process as the application of the adhesive to the first application area 10h. It is preferable. For example, the second application region 10p of the present embodiment is continuous with the first application region 10h, and the adhesive can be applied in a single stroke in the same process as the first application region 10h.

図８は、図７のＢ−Ｂ断面図（表示パネルあり）である。   8 is a cross-sectional view taken along the line BB in FIG. 7 (with a display panel).

この図に示すように、第１筐体１０の前面における開口部１０ｄの周囲と表示パネル６の裏面との間には隙間があり、これを光路として液晶モジュール５の光が光センサ１２に入り込み、光センサ１２の検出精度を低下させる可能性がある。そこで、本実施形態では、第２塗布領域１０ｐに塗布される接着剤として、遮光性を有する遮光性接着剤を用いる。例えば、不透明な有色の接着剤を用いる。このようにすると、前記光路から開口部１０ｄを介して光センサ１２に入り込もうとする光を、第２塗布領域１０ｐに塗布される接着剤で遮光することが可能になる。   As shown in this figure, there is a gap between the periphery of the opening 10d on the front surface of the first housing 10 and the back surface of the display panel 6, and light from the liquid crystal module 5 enters the optical sensor 12 using this as an optical path. The detection accuracy of the optical sensor 12 may be reduced. Therefore, in the present embodiment, a light-shielding adhesive having a light-shielding property is used as the adhesive applied to the second application region 10p. For example, an opaque colored adhesive is used. If it does in this way, it will become possible to shield the light which is going to enter into the optical sensor 12 from the said optical path through the opening part 10d with the adhesive agent apply | coated to the 2nd application | coating area | region 10p.

図９は、図６のＣ−Ｃ断面図（表示パネルあり）である。   9 is a cross-sectional view taken along the line CC in FIG. 6 (with a display panel).

図６および図９に示すように、携帯電子機器１Ｂでは、レシーバ１４の前方を開放するために第１筐体１０に形成された開口部１０ｆを囲うように第１筐体１０の前面に第３塗布領域１０ｒが形成されている。この開口部１０ｆは、表示パネル６に形成されるレシーバ用開口部６ａと連通するので、開口部１０ｄの周囲には防水用の接着が必要となる。なお、第１実施形態の説明では省略したが、第１実施形態の携帯電子機器１Ａにも第３塗布領域１０ｒが設けられる。   As shown in FIGS. 6 and 9, in the portable electronic device 1 </ b> B, the first front side of the first housing 10 is surrounded by an opening 10 f formed in the first housing 10 to open the front of the receiver 14. Three application regions 10r are formed. Since the opening 10f communicates with the receiver opening 6a formed in the display panel 6, waterproofing is required around the opening 10d. Although omitted in the description of the first embodiment, the third application region 10r is also provided in the portable electronic device 1A of the first embodiment.

本実施形態では、開口部１０ｆの周囲に第３塗布領域１０ｒを形成するにあたり、開口部１０ｆの開口の周囲と第３塗布領域１０ｒの間に、第３塗布領域１０ｒに塗布される接着剤が開口部１０ｆへ流れ込むのを規制するリブ１０ｓ（規制部）を立設している。このようにすると、接着剤の流れ込みによるレシーバ１４の機能不全を防止できるだけでなく、リブ１０ｓによる表示パネル６と第１筐体１０との間隔規定により、レシーバ１４の前面容積Ｙを安定させ、音響特性のバラツキを抑制することができる。   In the present embodiment, when the third application region 10r is formed around the opening 10f, the adhesive applied to the third application region 10r is between the periphery of the opening of the opening 10f and the third application region 10r. Ribs 10s (regulating portions) that restrict the flow into the opening 10f are provided upright. This not only prevents malfunction of the receiver 14 due to the inflow of adhesive, but also stabilizes the front volume Y of the receiver 14 by regulating the distance between the display panel 6 and the first housing 10 by the ribs 10s. Variations in characteristics can be suppressed.
